Description

Laundry treating apparatus and control method of the same

Technical Field

The present invention relates to a laundry treating apparatus and a control method of the laundry treating apparatus. More specifically, the laundry treatment apparatus and the control method of the laundry treatment apparatus are capable of performing deodorization, drying, wrinkle removal, and the like of laundry by injecting steam to the laundry.

Background

Generally, the concept of a laundry treatment apparatus includes a washing machine that removes foreign matters by a chemical action of a laundry detergent, a physical action of a drum rotation, etc., after wet laundry is made by wetting the laundry with water, and a dryer that dries the laundry in a wet laundry state by using hot wind and steam.

However, in recent years, there has been a growing advent of a laundry machine that keeps clothes comfortable and clean in a state of not being wetted with water for clothes in a dry state. Such a laundry care machine may deodorize laundry by supplying steam or hot air in a state that the laundry is hung, or perform a care (refresh) course of drying or sterilizing the laundry.

Such laundry care machines can selectively add fragrance even to the laundry, and in recent years, such laundry care machines have taken up an important weight in laundry treatment apparatuses in addition to washing machines and dryers.

Since the laundry care machine performing the care course of the laundry accommodates the laundry in a dry laundry state, a steam supply part supplying steam to the laundry is necessary.

Fig. 1 is a view showing a conventional laundry treating apparatus provided with a steam supply part.

Referring to korean laid-open patent publication No. 10-2020-0057545, a conventional laundry treating apparatus includes: a case 1 forming an external appearance; and an inner case 2 provided inside the case 1, and laundry placed in the inner case 2.

The laundry treating apparatus may be provided with: a circulation duct 13 provided at a lower portion of the inner casing 2 to circulate air of the inner casing 2; a heat exchanger 15 provided in the circulation duct 13 and configured to exchange heat with the air; and a compressor 14 for supplying a high-temperature refrigerant to the heat exchanger 15. When the compressor 14 is driven, hot air may be supplied to the inner case 2, thereby enabling the temperature inside the inner case 2 to rise, and the laundry may be dried or sterilized.

In addition, the laundry treating apparatus may include: a steam tank 16 provided outside the circulation pipe 13 and configured to store water; and a heater 17 accommodated in the steam tank 16, for heating water to generate steam. If the heater 17 is driven, steam is supplied to the inside of the inner case 2, thereby deodorizing or removing wrinkles of the laundry.

On the other hand, the laundry accommodated inside the inner case 2 is placed in a dry state. Therefore, in order to effectively care (Refresh) the laundry, sufficient moisture required for caring the laundry needs to be supplied to the inside of the inner case 2.

Accordingly, the heater 17 may be provided in a relatively large capacity so that the laundry placed in the inner case 2 can contain a sufficient amount of moisture. For example, the heater 17 may be set to have a rated capacity (RATED CAPACITY) larger than that of a heater applied to a washing machine or dryer for supplying steam to laundry in a wet laundry state.

As a result, the conventional laundry machine has a fundamental limitation that the heater 17 and the compressor 14 cannot be driven at the same time so as not to exceed the allowable rated capacity.

Therefore, there is a problem in that hot wind cannot be supplied into the inside of the inner case 2 when steam is supplied into the inside of the inner case 2 by driving the heater 17. That is, although the moisture content of the laundry can be increased by the steam supply to raise the temperature inside the inner case 2 by a predetermined level, there is a problem that the temperature inside the inner case 2 cannot be maintained at a minimum temperature or higher required for deodorization, sterilization and drying.

As a result, there is a limit that deodorizing and sterilizing performance of the laundry cannot be ensured when the steam 2 is supplied into the inside of the inner case 2.

Further, in the conventional laundry treating apparatus, sufficient moisture supply is required to care for laundry as compared with hot wind, and since it is required to dry all of the supplied moisture, the compressor 17 is required to be driven after the driving of the heater 17 is completed.

As a result, in the conventional laundry treatment apparatus, the temperature inside the inner case 2 cannot be kept at the minimum temperature before the compressor 17 is driven, and thus there is a problem that the effect of the progress of care cannot be exerted.

Therefore, in the progress of care, only at a point of time after the compressor 17 is driven, the temperature inside the inner housing 2 can be raised to the lowest temperature and maintained, and thus there is a fundamental limitation that the progress of care of the laundry can only be severely prolonged.

In addition, at an initial time point of driving the compressor 17, steam is not supplied to the inside of the inner case 2, and thus air in contact with the heat exchanger 15 corresponds to air having a relatively low temperature. As a result, the air discharged from the inner case 2 cannot secure sufficient heat quantity to exchange heat with the refrigerant flowing through the heat exchanger 15, and therefore, there is a problem that the coefficient of performance (COP: coefficient of Performance) of the heat pump system cannot be secured.

In addition, as described above, since the heater 6 is provided with a large capacity to increase the moisture content of the laundry inside the inner case 2, the humidity inside the inner case 2 increases sharply when the heater 6 is operated.

Therefore, the conventional laundry treatment apparatus has a problem that laundry such as silk or cashmere, which is susceptible to moisture, cannot be managed.

On the other hand, there has been a laundry treating apparatus having a steam supply part that supplies steam to a drum in which laundry is accommodated in the washing machine or the dryer.

Fig. 2 is a diagram illustrating a conventional laundry treating apparatus provided with a steam supply part that can perform drying.

Referring to korean patent laid-open publication No. 10-1448632, the existing laundry treating apparatus may include: a laundry accommodating portion 2 for accommodating laundry in the case 1; a water supply pipe 5 for supplying water to the inside of the clothes accommodating part 2; and a steam supply part 4 for receiving water by being connected to the water supply pipe 5 and supplying steam to the laundry accommodating part 2.

A heater 6 for generating steam by heating water may be provided inside the steam supply part 4. In this way, in the conventional laundry treatment apparatus, the steam is injected into the laundry accommodating portion 2 by the steam supply portion 4 during a washing course or a drying course, and thereby the washing efficiency or the drying efficiency, or wrinkles of the laundry are removed or sterilization is performed by increasing the temperature inside the laundry accommodating portion 2.

However, since the conventional laundry treatment apparatus such as the washing machine or dryer is premised on the treatment of laundry in a wet state, a large amount of steam is required to be generated in order to increase the moisture content of dry laundry inside the laundry accommodation portion 2 like a laundry care machine.

Therefore, the conventional laundry treating apparatus shown in fig. 2 does not need to provide a large capacity heater 6 like the laundry care machine.

Of course, in the existing laundry treating apparatus, the heater 6 may also have a first heater 61 and a second heater 62 that can be driven independently of the first heater 61, and be provided to adjust the steam supply amount.

However, existing laundry treatment apparatuses such as washing machines, dryers perform a dehydration course or a drying course of removing moisture from the laundry in the wet laundry state. Therefore, there is a fundamental limitation in that the heater 6 cannot be operated when a heat pump system including a compressor or a heating system including an air heater (hereinafter, referred to as a heating part) is driven while the laundry accommodating part 2 is rotated or a drying course is performed.

As a result, there is a fundamental limitation that even if laundry in a dry laundry state is put into the washing machine and dryer, the heater 6 and the heating part or motor cannot be simultaneously driven for caring for the laundry.

Further, in the case of performing a drying course in the laundry treatment apparatus such as the washing machine and the dryer, since laundry whose purpose is a wet laundry state is finally dried, even if the heater 6 is heated to supply steam during the drying course, it is not interrupted until the end once the heating part starts to drive. This is because, in this case, not only the drying performance is drastically reduced, but also the drying progress is greatly prolonged

Therefore, the washing machine and dryer have limitations in that not only a technique of simultaneously driving the steam generating heater and the compressor is not given, but also a possibility or a suggestion regarding a technique of driving the steam generating heater and interrupting the driving of the compressor after starting the driving of the compressor is not found at all.

As a result, the conventional laundry treatment apparatus has a limitation in that it is impossible to provide a technology for simultaneously driving a heater generating steam and a compressor generating hot air in the laundry treatment machine, or a technical content of how to control and apply the dual heater in the laundry treatment machine for treating laundry in a dry laundry state in the case that the heater is the dual heater.

The base part 310 may be provided with a control part setting part 312, and the control part setting part 312 forms a space in which the control part 700 can be inserted at a lower portion of the circulation duct 320.

The control unit 700 may be configured to control all the components that can be electronically controlled, for example, the compressor 342, the steam supply unit 800, the blower fan 353, and the like.

Since the control part 700 is inserted into and supported by the base part 310, vibration or impact applied to the control part 700 can be buffered. In addition, since the control unit 700 is disposed close to all the electronic components, occurrence of control errors such as noise can be minimized.

A steam supply unit is disposed above the circulation duct 320, and a control unit 700 is disposed below the circulation duct 320. Thereby, the circulation pipe 320 may be disposed in a straight pipe shape between the steam supply part 800 and the control part 700. Accordingly, the flow path resistance of the air passing through the circulation duct 320 can be minimized.

The circulation duct 320, the external air duct 370, the steam supply part 800, the control part 700, and the heat supply part 340 may be provided at the base part 310 in a module form.

Thus, the base portion 310 is introduced forward or backward to be led out of the machine room 300, so that installation and maintenance can be easily performed.

Fig. 5 (a) is a perspective view of the base portion 310 from the front, and fig. 5 (b) and 5 (c) are perspective views of the base portion 9310 from the rear.

The seating part 310 may be disposed above a seating plate forming a lower face of the laundry treating device. The seating part 310 itself may form a lower face of the laundry treating device.

The base portion 310 may include a base bottom 311 that forms a support surface. The base bottom 311 may form a lower face of the laundry treating device. In addition, the base bottom 311 may be provided at an upper surface of the cabinet 100 forming a bottom surface of a lower surface of the laundry treating apparatus.

The base portion 310 may be integrally provided with the circulation duct 320, and the circulation duct 320 may form at least a part of a flow path for air movement. The circulation duct 320 may be formed to extend upward from the base bottom 311.

The circulation pipe 320 may include: a pipe body 321 extending from the base bottom 311 to form a flow path; a heat exchanger installation portion 3212 that provides a space for installing the evaporator 341 or the condenser 343 inside the duct body 321; and an air discharge unit 323 provided at the rear of the duct body 321 and discharging air of the duct body 321.

The air discharge portion 323 may be provided in a pipe shape formed to extend rearward from the duct body 321. The diameter of the air discharge portion 323 may be smaller than the width of the duct body 321.

The air discharge portion 323 may be connected to the fan housing 350. The air discharged from the air discharge portion 323 may pass through the fan housing 350 and be guided to the inside of the inner case 200.

The circulation duct 320 may include an external air suction portion 322, and the external air suction portion 322 is formed through the front surface of the duct body 321.

The outside air suction part 322 may be provided to communicate with the outside air duct 370. The outside air duct 370 may be disposed and supported in front of the outside air suction part 322.

The circulation duct 320 may be provided with a damper for opening and closing the outside air suction portion 322. By opening and closing the damper, the inflow of the external air into the circulation duct 320 can be allowed or blocked.

The base portion 310 may include a compressor setting portion 312, the compressor setting portion 312 providing a space for setting the compressor 342. The compressor installation part 312 may be formed at one side of the base bottom 311 and integrally formed with the base bottom 311.

The compressor installation part 312 may be formed with a protrusion capable of supporting the compressor 342. The compressor installation part 312 may be disposed at a position biased to the rear of the base part 310. The compressor installation part 312 may be configured such that at least a portion overlaps with the air discharge part 323 in the width direction.

The compressor installation part 312 may be provided with a buffer member that reduces vibration transmitted from the compressor 342. The buffer member may be fixed to the protrusion.

The base portion 310 may include a control portion setting portion 313 that sets the control portion 700. The control portion setting portion 313 may be formed between the base bottom 311 and the circulation duct 320. The control part setting part 313 may be disposed between the base bottom 311 and the bottom surface of the circulation duct 320. The control unit setting unit 313 may be provided in a duct shape that is opened at either one of the front and rear sides in the lower portion of the circulation duct 320.

The structure of the control portion setting portion 313 will be described later.

The circulation duct 320 may extend from the bottom of the base to the upper portion to form a flow path for air flow. The circulation duct 320 may include a heat exchanger installation portion 3212, and the heat exchanger installation portion 3212 provides a space in which the evaporator 341 and the condenser 342 are installed. The heat exchanger installation part 3212 may be provided inside the duct main body 321.

The duct body 321 may be provided to be open at an upper face. The condenser 343 and the evaporator 341 can be put into and installed through the opening portion of the duct body 321.

The opening of the duct body 321 may be shielded by the base cover 360, and the base cover 360 and the duct body 321 may form a flow path of the circulation flow path 320.

The front surface of the duct body 321 may be spaced rearward from the front end of the base bottom 311.

Thus, the base bottom 311 may secure a support surface 3111 on which at least one of the water supply tub 30 or the water discharge tub 40 and the external air pipe 370 is mounted and supported.

On the other hand, the heating part 340 may include: an evaporator 341 provided inside the circulation duct 320 as a heat exchanger for dehumidifying by cooling the air flowing into the circulation duct 320; a condenser 343 provided as a heat exchanger for forming hot air by heating the air passing through the evaporator 341; a compressor 342 configured to supply the refrigerant, which exchanges heat with the air, to the condenser 343, and to be disposed outside the circulation pipe 320; and an expansion valve 344 for cooling the refrigerant having passed through the condenser 343 by expanding the refrigerant.

On the other hand, as the pipe body 32 is integrally formed with the base portion 310, the height of the heat exchanger installation portion 3212 can be secured more, and the heights of the condenser 343 and the evaporator 341 can be increased.

As a result, the width of the condenser 343 and the evaporator 341 in the front-rear direction can be reduced, and the number of refrigerant pipes passing through the condenser and the evaporator can be reduced. This has the effect of reducing the flow loss of air passing through the condenser and the evaporator.

On the other hand, the sum of the length of the evaporator 341 and the length of the condenser 343 may be smaller than the length of the heat exchanger arrangement portion 3212. Thus, the length of the heat exchanger installation portion 3212 in the front-rear direction may be equal to or less than half the length of the duct main body 321.

Therefore, the heat exchanger installation portion 3212 can be sufficiently spaced from the outside air suction portion 322, so that a sufficient space can be secured in which the outside air and the air inside the inner case 200 can flow into the circulation duct 320.

On the other hand, the inside of the duct body 321 may include a disposition partition wall 3211 dividing the heat exchanger disposition portion 3212 and the outside of the heat exchanger disposition portion 3212. The disposing partition wall 3211 may protrude from a side of the duct body 321 and support a front of the evaporator 341.

The duct body 321 may extend rearward with a width that is widened with respect to the installation partition wall 3211.

As a result, the width of the heat exchanger installation portion 3212 may be greater than half the width of the base portion 310. In addition, the circulation duct 320 may have a width greater than half of the width of the base portion 310.

The width of the condenser 343 and the width of the evaporator 341 can also be set to be greater than half the entire width of the base portion 310.

As described above, if the widths of the condenser 343 and the evaporator 341 are ensured, there is an effect that the heat exchange capacity can be sufficiently ensured.

In addition, the fan housing 350 may be configured to overlap with the condenser 343 or the evaporator 341 in the front-rear direction. Thus, the air having passed through the evaporator 341 and the condenser 343 can flow into the fan housing 350 without bending the flow path. That is, the air flowing into the circulation duct 320 has no flow path bending in the course of moving to the fan housing, so that there is an effect that the flow loss can be minimized.

The base portion 310 may be integrally formed with the circulation flow path 320 by injection molding the base portion 310 with a mold.

The mold forming the inner surface of the duct body 321 may be drawn out from the inside of the duct body 321 toward the upper direction and removed. At this time, the wall surface of the duct body 321 may be provided to be inclined at a prescribed angle with respect to the removal direction of the mold to facilitate drawing out of the mold.

The width of the lower face 321a of the duct body 321 may be greater than the width of the upper face 321b of the duct body 321.

Specifically, the distance between the wall surfaces of the duct body 321 facing each other may increase as it goes away from the base bottom 311. The distance between the left and right sides of the circulation flow path facing each other may increase along the drawing direction of the die. Thereby, the removal of the mold can be made easy.

On the other hand, the air discharging part 323 may include: an air extension pipe 3231 which is extended from the rear of the duct body 321 to have a smaller diameter or width; and an air outlet pipe 3232 extending from the air extension pipe 3231 in a pipe shape having a uniform diameter, and having a hollow 3233 formed therein. The air extension pipe 3231 may perform a nozzle function, thereby enabling an increase in the velocity of the discharged air.

In addition, the mold for molding the air discharge portion 323 may be removed as in the above figures. The air can be drawn forward from the inside of the air discharge portion 323 toward the inside of the circulation flow path 320, and then removed toward the upper open surface of the circulation flow path 320. In the process described above, the mold can be formed in a structure that facilitates drawing out of the mold.

Fig. 8 is a cross-sectional view of the circulation duct.

The disposing partition wall 3211 may be formed to protrude inward from the inner wall of the duct body 321 or to be recessed inward from the outer wall of the circulation duct.

The heat exchanger installation portion 3212 may be formed between the heat exchanger installation partition wall 3211 and the air discharge portion 323.

The mold forming the air discharge portion 323 may be removed by being drawn out to the upper portion after being drawn out to the front of the air discharge portion 323. When the mold forming the air discharge portion 323 is drawn forward from the inside of the air discharge portion 323, it is necessary to prevent interference with the heat exchanger-provided partition wall. For this reason, it is necessary to adjust the design value of the air discharge portion 323.

Specifically, when forming the air discharge portion 323, a mold on the molding front side and a mold on the molding rear side may be separately provided with reference to the parting line 3233 of the air discharge portion 323 in the drawing. Thereby, the removal directions of the molds may also be different from each other. The mold for molding the portion located at the front with reference to the parting line of the air discharge portion 323 may be drawn forward, and the mold for molding the portion located at the rear with reference to the parting line of the air discharge portion 323 may be drawn rearward.

That is, in order to prevent the mold drawn forward from interfering with the heat exchanger-provided partition wall during drawing, the first distance 323a in the drawing may be smaller than the second distance 321c. The first distance 323a may refer to a distance between a parting line of the air discharge portion 323 and a front end of the air discharge portion 323. In addition, the first distance 323a may refer to a distance between a parting line of the air discharge portion 323 and a rear opening portion of the circulation duct. The second distance 321c may refer to a distance between the front end of the air discharge portion 323 and the heat exchanger disposing partition wall. The second distance 323a may be a distance between the rear opening of the circulation duct and the heat exchanger installation partition wall 3211.

In the laundry treating apparatus of the present invention, if the compressor 342 and the blower fan 352 are driven, air supplied from the outside of the cabinet 100 and air supplied from the inner case 200 are cooled while passing through the evaporator 341, and water vapor contained in the air is condensed.

The water condensed at the evaporator 341 may be accumulated at the lower surface of the circulation duct 320.

The laundry treating apparatus of the present invention may include a water storage part 326, the water storage part 326 being formed by a depression of a portion of the bottom surface of the pipe body 321 to collect condensed water condensed at the evaporator 341.

The water storage part 326 is a space formed by being recessed in the bottom surface of the duct body 321, and may be formed as one side surface of the control part installation part 313.

The water storage part 326 may be formed to be recessed from the bottom surface of the circulation duct 320 toward the lower portion.

The water storage part 326 may be integrally formed with the circulation duct 320. The water storage part 326 may be formed by forming a portion of the bottom surface of the circulation duct 320 to be concave when the base part 310 is injection-molded with the circulation duct 320.

At least a portion of the top surface of the water storage part 326 may be disposed side by side with the heat exchanger disposing part 313.

The base part 310 may include a drain pipe 3263 to drain the water collected in the water storage part 326 to the outside.

The drain pipe 3263 may be provided to protrude from a lower portion of the water storage part 362 to an outside of the circulation pipe 320. The drain 32634 may drain the water stored in the water storage portion to the outside of the base portion. This prevents the water collected in the water storage unit 326 from being spoiled or from flowing back again to the bottom surface of the circulation pipe 320.

The circulation duct 320 is provided with the partition wall 3211 extending from an inner surface of the duct body 321. The partition wall 3211 may be protruded inward from the inner wall of the circulation duct 320 or may be formed by recessing the outer wall of the circulation duct 320 inward so as to be protruded inward. The partition wall 3211 may guide the position where the heat exchangers 341, 343 are disposed and prevent air entering the heat exchangers from bypassing the heat exchangers.

The partition wall 3211 may be provided at the water storage part 326.

The water storage part 326 may include: a bottom surface 3261, water accumulating on the bottom surface 3261; and a recess portion 3262 provided to be further recessed from the bottom surface 3261 toward a lower portion. The drain pipe 3263 may be disposed at a position corresponding to the recess 3262 in the outer surface of the circulation pipe 320. As a result, the drain pipe 3263 may be disposed at a portion of the water storage portion 326 having a lowest water level. The water collected in the water storage part 326 may move toward the water discharge pipe 3263 by its own weight.

Fig. 11 (a) is a view showing a vertical cross section parallel to the width direction of the base portion, and fig. 11 (b) is a view showing a vertical cross section parallel to the front-rear direction of the base portion.

The bottom surface of the circulation pipe 320 and the bottom surface of the water storage part 326 may be provided to have a predetermined inclination.

In particular, the bottom surface 325 of the circulation pipe may be disposed to be inclined toward the water storage part 326, and the bottom surface 3261 of the water storage part may be disposed to be inclined toward the drain pipe 3263.

The bottom surface 325 of the circulation pipe may be inclined toward the water storage part 326 by an angle corresponding to the first angle a with reference to the ground or the bottom surface of the base part 310.

In addition, the bottom surface 325 of the circulation duct may be disposed to be inclined downward toward the drain pipe 3263 in a direction from the rear toward the front. The bottom surface 325 of the circulation duct may be inclined at an angle corresponding to the second angle b with respect to the bottom surface of the base portion 310 in the rear-front direction.

As a result, the water condensed on the bottom surface of the circulation pipe can move toward the water storage part 326 while moving forward.

On the other hand, the bottom surface 3261 of the water storage portion may be provided to have a predetermined inclination.

The drain pipe 3263 may be disposed at an incline to the inner surface of the water storage part 326 instead of the outer surface.

The bottom surface 3261 of the water storage part may be provided to have an inclination that becomes lower toward the inside of the circulation pipe 320 with reference to the bottom surface of the base part 310.

The bottom surface 3261 of the water storage part may be inclined at an angle corresponding to the third angle c with reference to the bottom surface of the base part 310, and the inclination direction of the bottom surface 3261 of the water storage part may be opposite to the inclination direction of the bottom surface 325 of the circulation pipe.

The third angle c may be an angle inclined downward in a direction away from the partition wall 3211.

The bottom surface 3261 of the water storage part may be disposed at a lower inclination toward the drain pipe 3263.

The bottom surface of the water storage portion 3261 may be inclined with respect to the base portion 310 by a fourth angle d corresponding to a downward movement from the rear to the front.

The first to fourth angles described above may be formed by a mold during the molding of the base portion 310. The first to fourth angles may be formed during the molding of the circulation duct 320 or the water storage part 326. The second angle b and the fourth angle d may form inclinations in the same direction.

The mold for molding the water storage part 326 may be removed by being drawn out toward the upper part. At this time, in order to facilitate removal of the mold, the sidewall of the water storage part 326 may be provided to be tapered. Specifically, it may be configured that the sectional area along the drawing direction of the die increases. In other words, the periphery of the upper face of the water storage part 326 may be set to be larger than the periphery of the bottom face of the water storage part 326.

The front face of the water storage part 326 may be disposed to be inclined forward as approaching the upper side. The rear aspect of the water storage part 326 may be disposed to be inclined rearward as approaching the upper side. The left side surface of the water storage part 326 may be disposed to be inclined to the left as approaching the upper side, and the right side surface of the water storage part 326 may be disposed to be inclined to the right as approaching the upper side.

Fig. 12 (a) is a front-rear sectional view of the water storage unit, and fig. 12 (b) is a view showing a front lower surface of the circulation duct 320.

The water storage part 326 may be configured such that the bottom surface 3261 is inclined downward toward the front, and the bottom surface 325 of the circulation duct 320 may be configured such that it is inclined downward toward the front.

A filter 3264 may be provided at the recess portion 3262, thereby preventing foreign materials from being discharged to the outside of the drain pipe 3263.

The laundry treating apparatus of the present invention may include a residual water treating part 330, and the residual water treating part 330 may collect the water collected in the water storage part 326 to the drain tub 40.

The residual water treatment part 330 may include a drain pump 331, and the drain pump 331 discharges the water collected in the water storage part 326 to the drain tub 40. The drain pipe 3263 and the drain pump 331 may be connected using a first drain hose 3351, and water discharged from the drain pump 331 may move along the second drain hose 3352.

The drain pipe 3263 may be disposed at an upper portion of the drain pump 331. Thereby, the water collected in the water storage part 326 may be collected in the drain pump 331 by its own weight.

Since the condensed water collected in the water storage part 326 needs to be collected in the drain tub 40, the laundry treating apparatus of the present invention may be provided with a residual water treating part 330 collecting the condensed water in the drain tub 40.

On the other hand, since the drain tank 40 is provided in front of the duct body 321, it may be advantageous that the residual water treatment unit 330 is provided in front of the duct body 321.

On the other hand, a part of the residual water treatment part 330 connecting the drain pump 331 and the drain tub 40 may be provided at the base part 310. Thus, when the drain tank 40 is full or the condensed water flows back from the drain tank 40, the condensed water can be transferred again into the base portion 310 and circulated to the water storage portion 326. Thereby, the condensed water can be prevented from flowing outside the base portion 310.

The water storage part 326 may include a drain pipe 3263 to drain the condensed water to the outside of the water storage part 326. The drain pipe 3263 may be provided to extend forward from the base portion 310.

The residual water treatment part 330 may include a drain pump 331, the drain pump 331 providing power to transfer water discharged to the drain pipe 3263 to the drain tub 40.

The residual water treatment part 330 may include an inflow pipe 332, and the inflow pipe 332 extends from one side of the circulation pipe and communicates with the drain pump 331.

The residual water treatment part 330 may include a drain pipe 334, the drain pipe 334 communicating with the inflow pipe 332 and transferring the condensed water to the drain tub 40, and the drain pipe 334 may be integrally provided with the base part 310.

The residual water treatment part 330 may further include a guide pipe 333 provided at a lower side of the discharge pipe. The guide pipe 333 may be provided to communicate the drain tub 40 with the circulation pipe 320. In case that the water level of the drain tub 40 is above a preset water level, the guide pipe 333 may guide the water inside the drain tub to the inside of the circulation duct 320 again.

The water guided to the circulation pipe 320 may be again recovered to the water storage part 326 and guided to the drain tub 40 again through the residual water treatment part 330.

As a result, even when the drain tank 40 is in a full water level state, the condensed water can flow into the circulation pipe 320 through the guide pipe 333, and thus water overflow (overflow) of the drain tank 40 can be prevented.

The drawing of the recovery flow path structure is deleted.

Fig. 14 is a diagram showing an embodiment of a water cap.

The laundry treating apparatus of the present invention may further include a water cover 327 disposed at the bottom surface of the circulation duct 320. The water cover 327 may be provided to support at least one of the evaporator 341 and the condenser 343, and to guide water condensed at the evaporator 341 to move toward the water storage part 326 while blocking the movement toward the condenser 343.

The water cover can prevent the bottom surface of the circulation pipe from being exposed to the outside. In addition, the water cover may form a support surface for supporting the evaporator and the condenser. The water cover may support the evaporator and the condenser to be spaced apart from the bottom surface of the circulation duct. The water cover may be provided to shield the top surface of the water storage part. That is, the water cap may perform a cap function of the water storage part.

The water cover 327 may be provided to cover the upper portion of the water storage part 326. This can prevent the air flowing into the circulation duct 320 from being subjected to resistance by the step between the water storage unit 326 and the circulation duct 320.

The water cap 327 may include: a water cover body 3271 having a plate shape and supporting at least one of the evaporator 341 and the condenser 343; and a support rib 3276 extending downward from the water cap body 3271, so that the height or inclination of the water cap body 3271 is maintained.

Any one of the support ribs 3276 may be supported at the recess 3262 or the filter 3264. Thus, the support rib 3276 can guide water flowing along the water cap body 3271 directly to the drain pipe 3263.

The water cover 327 may be provided in a plate shape shielding at least a portion of the bottom surface of the circulation duct 320.

The water cover 327 may block the water storage part 326 from being exposed to a region facing the inflow part 362 or a region into which the external air flows.

The water cover 327 may be provided to support lower ends of the evaporator 341 and the condenser 343. Even if the bottom surface of the circulation duct 320 is inclined by the water cover 327, the evaporator 341 and the condenser 343 may be disposed at the same height.

In addition, the water cover 327 may prevent the positions of the evaporator 341 and the condenser 343 from being changed.

The water cap body 3271 of the water cap 327 may be disposed at an inclination parallel to the base part 310. This can prevent the air flowing into the evaporator 341 from receiving unnecessary inclination resistance.

Fig. 16 is a view showing a detailed structure of the water cap.

The water cover may include a water cover body 3271, and the water cover body 3271 is located at an upper side than a bottom surface of the circulation pipe or a bottom surface of the water storage part. The water cover body 3271 may prevent the bottom surface 325 of the circulation pipe or the bottom surface 3261 of the water storage part from being exposed to the outside.

The water cap 327 may include a seating rib 3274 protruding upward from the water cap body 3271. The disposition rib 3274 may be provided to fix at least one of the evaporator 341 and the condenser 343, and may maintain a space between the evaporator 341 and the condenser 343.

The water cap 327 may include a through hole 3272 penetrating the water cap body 3271. The through hole 3272 may be formed between the evaporator 341 and the condenser 343. Thereby, the water condensed at the evaporator 341 can be guided to the lower portion of the water cover.

The water cap 327 may further include a water outlet 3275, the water outlet 3275 extending through the water cap body 3271 and being spaced apart from the through hole 3272. The water outlet 3275 may be disposed in an area facing the water storage portion 326.

The water outlet 3275 may discharge water flowing along an upper face of the water cap body 3271 toward the water storage part 326.

The water outlet 3275 may guide water overflowed from the water discharge tub 40 to the water storage part 326.

The water cover 327 may include a separation rib 3273, and the separation rib 3273 is provided to the water cover body 3271 and is supported at the bottom surface of the circulation duct 320. The separation rib 3273 is provided to correspond to the inclination of the bottom surface of the circulation duct 320 and to be in contact with the bottom surface of the circulation duct 320, thereby blocking the air from moving between the water cap body 3271 and the bottom surface of the circulation duct 320.

On the other hand, the separation rib 3273 may be provided along the circumference of the water cap body 3271.

On the other hand, the water cover 3273 may further include an avoidance portion 3277, and the avoidance portion 3277 may prevent interference with the partition wall 3211 of the circulation pipe. The avoidance portion 3277 may be recessed from a side surface of the water cap body 3271. The avoidance portion 3277 may be provided to correspond to the shape of the partition wall.

The water cap 327 may include a drain rib 3276 supported at the water storage portion 326. The drain bar 3276 may be provided in a shape not to shield the drain pipe 3263.

Fig. 17 (a) is a diagram showing a mode in which the control unit 700 is provided in the control unit providing unit 313.

The control part 700 may be configured to control all devices required when the laundry treating apparatus of the present invention performs any program for performing a care course on laundry. The control unit 700 may be provided as a PCB substrate, but is not limited thereto, and may be provided as various means for control.

The control part 700 may be inserted into and disposed at the control part setting part 313.

The control unit setting unit 313 may be disposed at a lower portion of the circulation duct 320.

The bottom surface of the circulation duct 320 may form the top surface of the control portion setting portion 313. The control unit setting unit 313 may be disposed below the air discharge unit 323.

The control portion setting portion 313 may be integrally formed with the base bottom 311. The control part setting part 313 may be formed as a space recessed at a lower portion of the circulation pipe in the process of molding the circulation pipe 320 to the base part 310.

The control unit 700 may be slidably introduced from the rear to the front in the control unit setting unit 313.

Fig. 17 (b) is a diagram of a state in which the control unit is provided in the control unit setting unit.

As shown, the control part 700 may be disposed to form a prescribed angle with the base bottom 311.

For example, the control part 700 may be disposed obliquely toward the water storage part 326. Thus, in case that water flows to the upper portion of the control part 700, the water may be rapidly separated from the control part 700, and the bottom surface of the circulation duct 320 may be formed to be inclined toward the water storage part 326.

The control part 700 may include a supporter 3132 formed to protrude sideways.

The ribs 3134 may be integrally formed with the base portion 310. The ribs 3134 may be integrally formed with the base bottom 311, the circulation duct 320, and the like when the base portion 310 is injection molded.

A protrusion 3133 formed to protrude may be provided at the front of the control part 700. Further, a guide protruding rearward may be provided on the inner surface of the control unit installation portion 313. The protrusion may be combined with the guide. The protrusion may be inserted into the guide. When the control portion is introduced into the control portion setting portion, the control portion can be aligned to a prescribed position by bonding the projection to the guide.

In addition, as described above, the positions of both side surfaces of the control part may be determined in such a manner that the support member is mounted to the rib. By the bonding process as described above, the control portion can be bonded to the prescribed position of the control portion setting portion without an additional fastening member.

The base portion 310 may include an air discharge portion 323 that discharges the processed air toward the fan housing.

The air discharge portion 323 may be provided to communicate the inside of the circulation duct 320 or the duct body 321 and the fan housing 350. The air discharge portion 323 may be provided in a bell mouth shape. By providing in a bell-mouth shape, the flow loss of air can be reduced and the air circulation efficiency can be improved.

The air outlet pipe 3232 of the air outlet portion 323 may be provided in a pipe shape, and a mold disposed in front of the parting line 3233 may be drawn forward and a mold disposed in rear of the parting line 3233 may be drawn backward during the mold removal process based on the parting line 3233.

The fan housing 351 may include a discharge duct 352, and the discharge duct 352 may extend from an outer circumferential surface or an outer side of the blower fan 353 toward the discharge hole 232.

A flow path which accommodates the blower fan 353 and through which air can move may be formed inside the fan housing 351 and the exhaust duct 352.

A motor for rotating the blower fan 353 may be coupled to the outside of the fan housing 351 and supported.

The base cover 360 may be combined with an upper surface of the circulation duct 320 and configured to prevent the inside of the circulation duct 320 from being exposed.

The base cover 360 may include: an inflow body 361 coupled to an upper surface of the circulation duct 320 to communicate the inner case 200 and the circulation duct 320; and a shielding body 363 extending from the inflow body 361 to shield the circulation pipe 320.

The inflow body 361 may have a pipe shape and be provided to communicate the inflow hole 231 of the inner case and the inside of the circulation pipe 320. The inflow body 361 may protrude more upward than the shielding body 363.

The inflow body 361 may be disposed at a position forward of the evaporator 341 so as not to face the evaporator 341 and the condenser 343, and may be disposed at a position forward of the partition wall 3211.

The inflow body 361 may function as an inflow duct that moves the air of the inner case 200 toward the circulation duct 320.

An inflow portion 362 through which air of the inner case 200 can pass may be provided inside the inflow body 361.

Specifically, the base cover 360 may include: the first rib 362a extending along the width direction of the inflow body 361; and a second rib 362b spaced rearward from the first rib 362a and extending along the width direction of the inflow body 361.

The second inlet 3622 may be provided with a blocking filter 366, and the blocking filter 366 may allow air to pass through, but may be capable of filtering foreign substances such as fine dust and fluff.

The blocking filter 366 may be configured to divide the first inlet 3621 and the third inlet 3623 by being inserted into the second inlet 3622. The blocking filter 366 may be extended from the second inlet 3622 to be in contact with the bottom surface of the circulation pipe 320.

The blocking filter 366 may be provided as a filter that is capable of filtering even the moisture. For example, the blocking filter 366 may be provided as a HEPA filter or the like.

On the other hand, the second inflow port 3622 may further incorporate a shielding member that shields the second inflow port 3622 if the blocking filter 366 is inserted.

The driving part 365 may include: a motor that provides power capable of selectively rotating the first damper part 364 and the second damper part 365; and a plurality of gear members capable of selectively rotating the first damper part 364 and the second damper part 365 as they are rotated by engagement with the motor.

The first inlet 3611 and the third inlet 3623 can be selectively opened by the driving unit 365.

The air contained in the inner case 200 can flow into the circulation duct 320 along the first inlet 3621 and can flow into the circulation duct 320 along the third inlet 3623 by the driving unit 365.

Of course, the driving unit 365 may control the first damper 3641 and the second damper 3642 to open the first inlet 3611 and the third inlet 3623, and may control the first damper 3641 and the second damper 3642 to block the first inlet 3611 and the third inlet 3623.

The driving unit 365 may be provided in any configuration as long as the first damper 3641 and the second damper 3642 can be rotated.

The circulation duct 320 may be provided with a coupling portion detachably coupled to the inflow hook 3612.

Fig. 20 is a view showing the structure of an external gas pipe.

Referring to fig. 20 (a), the external air duct 370 may be combined with the base part 310.

The outside air duct 370 may be provided to communicate with the outside air suction part 322.

The external gas pipe 370 may include: an outside air damper 373 for opening and closing the outside air suction portion 322; and an outside air driving part 374 selectively opening the outside air suction part 322 by rotating the outside air damper 373.

The outside air damper 373 may be provided in a plate shape capable of sealing the outside air suction portion 322, and may be rotatably coupled to both side surfaces of the outside air suction portion 322.

The outside air driving part 374 may be provided as an actuator that is coupled to the outside air duct 370 or the circulation duct 320 and rotates the outside air damper 373.

The external gas pipe 370 may include: an extension duct 372 extending forward from the outside air suction portion 322 in front of the outside air suction portion 322; and an intake duct 371 extending forward from the extension duct 372, into which external air can flow.

The suction pipe 371 may be extended at a lower portion of the extension pipe 372, and the water supply tub 30 and the drain tub 40 may be disposed at an upper portion of the suction pipe 371. The water supply tub 30 and the water discharge tub 40 may be combined with or installed at the suction pipe 371.

The suction pipe 371 may include: an external air port 3711, through which external air is sucked from one end or free end of the external air port 3711; and dividing ribs 3712 provided to divide the outside air port 3711.

The external air port 3711 may be disposed at a lower position than the door 400 and not to shield the door 400.

The dividing rib 3712 may be provided to divide the inside of the outside air port 3711 and block foreign objects or the user's body from being thrown in.

In fig. 20 (b), if the outside air driving part 374 rotates the outside air damper 373 to open the outside air suction part 322, the suction pipe 371 and the circulation pipe 320 may be communicated.

At this time, if the blower fan 352 is driven, the air outside the case may flow into the circulation duct 320. If the compressor 342 is driven, the external air may be dehumidified and supplied to the inside of the inner case 200 while passing through the circulation duct 320.

The door 400 may further include: a discharge port for discharging air inside the inner case 200 to the outside; and a discharge damper selectively opening and closing the discharge port. The discharge port may be provided to face the receiving space of the inner case 200.

Thereby, the dehumidified air may be discharged from the discharge port.

In addition, the external air may be filtered and discharged again to the outside of the case 100 while passing through the blocking filter 366.

Fig. 21 is a view showing an air flow flowing through the circulation duct.

Referring to fig. 21 (a), the outside air damper 373 may be controlled to block the outside air intake portion 322, the first damper 3641 may open the first inflow port 3621, and the second damper 3642 may be controlled to block the third inflow port 3623.

If the blower fan 352 is driven, air inside the inner case 200 may flow in from the first inlet 3621 and be filtered while passing through the filter 366.

If the compressor 342 is driven, the air passing through the filter 366 may be dehumidified and heated in passing through the evaporator 341 and the condenser 343.

The air passing through the heat exchanger may be supplied to the inside of the inner case 200 via the fan setting part 350.

This state may be a state in which steam is not supplied to the inner case 200. This is because, if steam is supplied to the inner case 200, the moisture wets the filter 600, so that the performance of the filter 366 cannot be ensured.

As a result, in a state where steam is not supplied to the inner case 200, before steam is supplied to the inside of the inner case 200, or even after steam is supplied to the inside of the inner case 200 but the humidity becomes low, air inside the inner case 200 can be filtered out foreign substances such as fluff through the first inflow port 3641 and in the course of passing through the filter 366.

Referring to fig. 21 (b), the outside air damper 373 may be controlled to block the outside air intake portion 322, the first damper 3641 may block the first inflow port 3621, and the second damper 3642 may be controlled to open the third inflow port 3623.

If the blower fan 352 is driven, air inside the inner case 200 may flow into the third inflow port 3623. Since the third inflow port 3623 is located downstream of the blocking filter 366, the air flowing in from the third inflow port 3623 may not pass through the blocking filter 366.

If the compressor 342 is driven, the air passing through the filter 366 may be dehumidified and heated while passing through the evaporator 341 and the condenser 343.

As a result, in a state where steam is supplied to the inner case 200 or in a state where humidity inside the inner case 200 is very high, air of the inner case 200 can be caused to flow in from the third inflow port 3623 while blocking inflow from the first inflow port 3621, whereby exposure of the blocking filter 366 to moisture can be blocked.

Referring to fig. 21 (c), the outside air damper 373 may be controlled to open the outside air intake portion 322, the first damper 3641 may cover the first inflow port 3621, and the second damper 3642 may cover the third inflow port 3623.

If the blower fan 352 is driven, the inflow of air from the inflow part 362 in the inner case 200 is blocked, and only the external air of the case 100 may flow into the circulation duct 320 and pass through the blocking filter 366. Thus, the blocking filter 366 can filter foreign substances such as fine dust contained in the outside air.

If the compressor 342 is driven, the air passing through the filter 366 may be dehumidified while passing through the evaporator 341 and the condenser 343.

The air passing through the heat exchanger may be supplied to the inside of the inner case 200 via the fan setting part 350, so that fresh hot air can be supplied to the laundry.

At this time, if a means for exhausting the air inside the inner case 200 to the outside is provided at the door 400, the air outside the case may pass through the blocking filter 366 and the heat supply part 340 and be exhausted in a purified and dehumidified state.

As a result, in the laundry treating apparatus of the present invention, the flow direction of the air inside the inner case 200 and the air outside the cabinet can be determined by controlling the outside air driving part 374 and the inflow driving part 365 by the control part 700.

Fig. 22 is a view showing an arrangement structure of the steam supply part.

The steam supply part 800 may be disposed and supported at the base cover 360.

The steam supply part 800 may include a steam housing 810, and the steam housing 810 is disposed at the base cover 360 and stores water generating the steam.

The set bracket 870 may be coupled with the base cover 360 and fix the steam housing 810.

The setting bracket 870 may include: a lower panel 871 supporting a lower face of the steam housing 810; and side panels 872 supporting both sides of the steam case 810 at the lower panel 871.

The setting bracket 870 may also include one or more retaining clips 873 that extend from the side panels 872 and prevent the steam housing 810 from disengaging.

The fixing clip 873 may be detachably provided to an upper portion or a side of the steam housing 810.

The compressor 342 may be disposed at a lower portion than the steam supply part 800.

The setting bracket 870 may be configured to block heat generated at a compressor or heat generated at a refrigerant compressed by the compressor from being transferred to the steam supply part 800.

The set bracket 870 may also block the transmission of a fire to the steam supply 800 in the event of a fire to the compressor 342.

On the other hand, the base cover 360 may include a fastening portion 3631, and the fastening portion 3631 is provided to the shielding body 363 and detachably coupled to the steam supply portion 800. The fastening part 3631 may be provided in a structure to be detachably coupled with a protruding part protruding from a lower portion of the steam case 810.

Thereby, even though a large amount of water is contained inside the steam housing 810, the steam housing 810 can be stably seated on the base cover 360.

In addition, since the steam housing 810 is disposed at an upper portion of the circulation duct 320, a distance from the inner housing 200 is smaller than that of the circulation duct 320, and thus, it is possible to minimize condensation before the steam generated by the steam housing 810 reaches the inner housing 200.

Fig. 23 is a view showing a detailed structure of the steam supply part.

Referring to (a) of fig. 23, the steam supply part 800 may include: a steam housing 810 capable of receiving and storing water for generating steam; and a heating part 840 accommodated in the steam case 810, for heating the water to generate steam.

The steam case 810 may be provided in a case shape of an upper opening, and accommodates the heating part 840.

The steam supply part 800 may further include a case cover 820 coupled to the steam case 810, and preventing the heating part 840 from being exposed to the outside and the water from flowing out.

The housing cover 820 may be provided with: a water level sensor 850 sensing a water level of the steam housing 810; and a steam sensor 860 sensing a temperature inside the steam housing 810 or sensing whether steam is generated inside the steam housing 810.

Referring to (b) of fig. 23, the steam housing 810 may include a housing body 811, the housing body 811 providing a space storing the water and accommodating the heating part 840.

The housing body 811 may be provided in a shape of an upper opening, so that various components can be easily provided inside the housing body 811.

The housing body 811 may include a heater insertion hole 8111, the heater insertion hole 8111 penetrating one side of the housing body 811, and the heater 840 may be inserted into or drawn out of the housing body 811.

The housing body 811 may include a recovery pipe 814, and the recovery pipe 814 may discharge water contained inside the housing body 811 to the outside.

The recovery pipe 814 may be maintained in a state of being blocked by a shielding cover 8141 to be opened only when residual water inside the steam housing 810 is removed, and may include a shielding clip 8142, the shielding clip 8142 maintaining the shielding cover 8141 in a state of being coupled to the recovery pipe 814 to prevent the shielding cover 8141 from being arbitrarily separated.

Thus, when repairing the steam case 800 or preventing frost crack of the steam case 800, etc., water inside the steam case 800 may be discharged through the recovery pipe 814.

On the other hand, a heater fixing portion 830 may be provided inside the housing body 811, and the heater fixing portion 830 may support or fix the heating portion 840. The heater fixing part 830 may include: a fixing clip 831 for fixing the heating portion 840; and a clamping and fixing member 833 for fixing the supporting clip 831 to the housing main body 811.

The retaining clip 831 can be configured to receive or surround at least a portion of the heating portion 840.

On the other hand, the steam supply part 800 may be provided with a water supply pipe 815 receiving water. The water supply pipe 815 may be configured to receive water by communicating with the water supply tub 30.

The water supply pipe 815 may be provided to the housing cover 820 or may be disposed at an upper portion of the steam housing 810. This prevents water from flowing back again through the water supply pipe 815.

The steam supply part 800 may be provided with a steam pipe 813, and the steam pipe 813 discharges the steam generated by the driving of the heating part 840 to the outside. The steam pipe 813 may be provided at an upper portion of the housing cover 820 so as to prevent water from being discharged to the steam pipe 813. The steam pipe 813 may communicate with the steam hole 233 of the inner case 200.

The housing cover 820 may be provided with a water level sensor hole 854 where the water level sensor may be disposed.

The water level sensor 850 may include: one or more contact protrusions 852, the contact protrusions 852 being inserted into the water level sensor hole 854 and sensing a water level by being immersed in water; and a sensor body 851 coupled to the water level sensor hole 854 or supported by the housing cover 820 so that the contact protrusion 852 maintains a floating state inside the steam housing 810.

The sensor body 851 may be coupled with the housing cover 820 using a sensor fastening member 853.

On the other hand, the case cover 820 may be provided with an insertion hole 864, and the steam sensor 860 may be disposed at the insertion hole 864. The steam sensor 860 may include: a sensing device 861 inserted into the insertion hole 864 to sense whether steam is generated inside the steam housing 810; a support table 863 for fixing the sensing device 861 to the housing cover 820; and a coupling member 862 for coupling the support 863 to the housing cover 820.

The sensing device 861 may be provided in a humidity sensor or a temperature sensor, and senses whether steam is generated inside the steam housing 810.

On the other hand, the case cover 820 may be provided with a cover hook 821, and the cover hook 821 may extend forward and be coupled with the base cover 860.

In addition, a fixing protrusion 822 may be further provided at the rear of the case cover 820, and the fixing protrusion 822 may fix the lower portion of the inner case 200 or the additional steam discharge portion 900.

The heating part 840 may be inserted into the heater insertion hole 8111 and received in the steam housing 810, and the heating part 840 may be configured to heat water by receiving electric power.

The heating unit 840 may be provided as a sheath heater or the like, and may be controlled by the control unit 700 to be repeatedly driven and stopped.

The heating part 840 may include: a first heater 841 for heating water by receiving the first power; and a second heater 842 for heating water by receiving power greater than the first power.

As a result, the second heater 842 may be configured to heat more water and generate more steam than the first heater 841.

The first and second heaters 841 and 842 may be configured to share and consume the maximum heater power allowed by the heating part 840 of the laundry treating apparatus. That is, if set to a portion where the first heater 841 consumes the maximum heater power, the second heater 842 consumes the remaining portion of the maximum heater power.

For example, in the case where the normal maximum heater power allowed by the heating part 840 is 1500w, the first heater 841 may be set to consume 600w, and the second heater 842 may be set to consume 880w. In consideration of errors and the like, 20w may be allocated less.

Of course, the heating unit 840 may include three or more heaters. For example, the first, second and third heaters 841, 842, 843 may be included and configured such that the first, second and third heaters 841, 842, 843 share and consume maximum heater power.

Hereinafter, description will be made with reference to a case where the heating unit 340 includes the first heater 841 and the second heater 842.

The first heater 841 and the second heater 842 may be formed of metal pipes in the form of a "u".

The heating part 840 may include a heater seal 843, the heater seal 843 may fix the first and second heaters 841 and 842 and seal the heater through hole 8111, and the heating part 840 may include a terminal part 844 supplying current to the first and second heaters 841 and 842.

The terminal portion 844 may include: a first terminal 844a for supplying current to the first heater 841; and a second terminal 844b that supplies current to the second heater 842.

The first heater 841 and the second heater 842 may be configured at the same height. Thus, the first heater 841 and the second heater 842 may be configured to generate steam by heating water of the same water level.

Thereby, the control part 700 can adjust the amount of generated steam and the amount of power consumption by using the first heater 841 and the second heater 842 in whole or selectively.

Fig. 24 is a view showing the inside of the steam housing.

The steam case 810 may have a heating space 817, store water inside the heating space 817, and accommodate the heating part 840.

In addition, the steam housing 810 may receive water for generating steam through a water supply hose 8151 connected to the water supply pipe 815.

On the other hand, in the steam case 810, the steam generated by the driving of the heating part 840 may be discharged to the outside of the steam supply part 800 through the steam discharge pipe 813 and along the steam hose 8131.

The steam hose 8131 may communicate with the steam hole 233 of the inner case 200.

On the other hand, the steam housing 810 may be provided with a partition wall 812 capable of separating the heating space 817 and the water level sensor 850. That is, the partition wall 812 may be provided to separate the heating part 840 and the water level sensor 850, and be disposed to be biased to one side of the housing body 811.

The water level sensor 850 may be disposed between the partition wall 812 and the inner surface of the housing body 811.

This prevents the water vibration generated when the water is boiling from being transmitted to the water level sensor 850, and prevents the heat generated by the heating unit 840 from being directly transmitted to the water level sensor 850.

Fig. 25 is a view showing a steam supply part provided with the heating part.

Referring to fig. 25 (a), the steam sensor 860 may be disposed at an upper portion of the heating part 840, and configured to sense a temperature or the like inside the steam case 810. Thus, when the temperature of the water reaches 100 degrees or a high temperature, the steam sensor 860 may sense that steam is generated.

The heating part 840 is supported by the support clips 832, so that the heating part 840 can be prevented from contacting the bottom surface of the steam case 810, etc.

Further, the upper portion of the heating part 840 is surrounded by the fixing clip 831, so that a change in the water level where the heating part 840 is disposed can be prevented.

Referring to (b) of fig. 26, the heater sealing member 844 of the heating portion 840 may include a first supporting hole 8441, and the first heater 841 penetrates the first supporting hole 8441 and is supported: and a second support hole 8442 through which the second heater 842 penetrates and is supported by the second support hole 8442.

The first length L1 of the first support hole 8441 spaced apart from the bottom surface of the steam housing 810 and the second length L2 of the second support hole 8442 spaced apart from the bottom surface of the steam housing 810 may be identical to each other.

The set height may be the same even if the diameters of the first support hole 8441 and the second support hole 8442 are different from each other.

Thus, the first heater 841 and the second heater 842 may heat the same water level to generate steam.

The allowable power of the laundry treating apparatus of the present invention may be set. For example, the allowable power may be smaller than power consumed when the first heater 841, the second heater 842, and the compressor 342 are simultaneously driven.

In addition, the allowable power may be larger than power consumed when the first heater 841 and the second heater 842 are driven simultaneously.

In addition, the allowable power may be greater than power consumed when the first heater 841 and the compressor 342 are simultaneously driven.

In addition, the allowable power may be greater than power consumed when the second heater 842 and the compressor 342 are simultaneously driven.

As a result, the laundry treating apparatus of the present invention may generate steam by simultaneously driving the first heater 841 and the second heater 842.

In addition, the laundry treating apparatus of the present invention may simultaneously drive either one of the first heater 841 and the second heater 842 and the compressor 342. Thereby, the steam can be supplied into the inner case 200 and the hot air can be supplied into the inner case 200.

The laundry treating apparatus of the present invention may rapidly generate steam by simultaneously driving the first heater 841 and the second heater 842 at an initial stage, and if steam is generated, may maintain steam generation by driving only any one of the first heater 841 and the second heater 842.

In addition, the laundry treating apparatus of the present invention may adjust the steam supply amount by driving only any one of the first heater 841 and the second heater 842. Thus, the care course can be sufficiently performed also for materials such as silk or cashmere which are susceptible to moisture and temperature.

In addition, the laundry treating apparatus of the present invention may reduce the amount of electric power required for the steam supply by using only any one of the first heater 841 and the second heater 842, and the compressors 342 may be driven together when the steam is supplied.

Fig. 26 (a) is a diagram showing a control method of a conventional laundry treatment apparatus.

In the existing laundry treating apparatus, a steam preparing step A1 of heating water by driving a heater is performed if a program of caring for laundry is performed, and a steam spraying step A2 of supplying steam to laundry is performed if water is heated to generate the steam.

In this case, since the conventional laundry treatment apparatus is intended to supply moisture to laundry in a dry state, the steam injection amount is large and the power consumption of the heater is also very large. Therefore, the conventional laundry treating apparatus has a limitation that the heater and the compressor cannot be driven simultaneously.

Therefore, in the steam spraying step A2, the conventional laundry treating apparatus drives only the heater.

After that, a waiting step A3 of providing time such that the laundry contains moisture using the supplied steam is performed. After that, a cooling step A4 of operating only the blower fan to prevent heat loss of the laundry is performed before driving the compressor. If the temperature inside the inner case 200 is lowered and the moisture content of the laundry is sufficient, a drying step A5 of driving the compressor is performed.

A care course of deodorizing, removing wrinkles, etc. of the laundry may be performed while drying the moisture contained in the laundry through the drying step A5. The duration of the drying step A5 is longest compared to all the previous steps.

However, the conventional laundry treating apparatus cannot drive the compressor in the steam spraying step A2, and thus cannot supply hot wind. Accordingly, the internal temperature of the inner case 200 and the temperature of the refrigerant of the heat supply part 400 correspond to relatively low temperatures until the drying step A5.

Therefore, in the conventional laundry treatment apparatus, care performance including any one of complete drying, sterilization, deodorization, wrinkle removal, and the like of laundry can be ensured only when the drying step A5 is continued for a relatively long time.

However, as described above, the laundry treating apparatus of the present invention may simultaneously drive the heater and the compressor. In other words, even though the laundry treating apparatus of the present invention allows the maximum power to be the same and the power consumption amount of the entire heater to be the same or similar as the existing laundry treating apparatus, since the heater is divided into a plurality, it is possible to simultaneously drive a part of the heater and the compressor.

Accordingly, the laundry treating apparatus of the present invention can rapidly raise the temperature inside the inner case 200 before the drying step by simultaneously driving the heater and the compressor before the drying step, thereby enabling to secure absolute time required for complete drying, sterilization, deodorization, and wrinkle removal of laundry. As a result, the duration of the drying step can be shortened. At this time, since the duration of the drying step is set to be the longest, the duration of the entire care course can be greatly reduced by shortening the duration of the drying step. In addition, the energy efficiency can be greatly improved by shortening the driving time of the compressor.

Fig. 26 (B) is a diagram illustrating an embodiment of a control method of the laundry treating apparatus of the present invention.

In the laundry treating apparatus of the present invention, if an arbitrary program capable of caring for or managing laundry is performed, the steam preparing step B1 of driving the heating part 340 may be performed to supply steam to the laundry.

Since the faster the steam is generated, the shorter the care course time can be, all the heaters of the heating part 340 can be driven in the steam preparing step B1.

In other words, in the steam preparing step B1, the water may be heated using the maximum power of the heating part 340.

For example, in the case where the heating unit 340 is configured by the first heater 341 and the second heater 342, the first heater 341 and the second heater 342 may be driven simultaneously to heat water.

In the steam preparing step B1, if it is sensed by the sensing device 860 that steam is generated inside the steam case 810, the laundry treating apparatus of the present invention may perform the preheating step B2 of driving only any one heater of the first heater 341 and the second heater 342.

That is, after the steam housing 810 generates the steam, the steam may be continuously supplied to the inner housing 200 even if only any one of the first heater 341 and the second heater 342 is used.

Accordingly, in the preheating step B2, only any one of the first heater 341 and the second heater 342 may be used to supply steam to the inner case 200, whereby the moisture content of the laundry may be increased while increasing the temperature inside the inner case 200, and further, the usable additional power consumption may be ensured.

In the preheating step B2, the laundry treating apparatus of the present invention may supply hot wind to the inner case 200 by simultaneously driving the compressor 342.

In other words, in the preheating step B2, either one of the first heater 841 and the second heater 842 and the compressor 342 may be driven at the same time. Thereby, steam and hot air can be simultaneously supplied into the inner case 200. Therefore, it is possible to raise the temperature inside the inner case 200 from the initial stage of the care course, and to improve the heat exchange performance of the evaporator 341, and even to improve the coefficient of performance (cop) of the heat supply portion 340.

In addition, since the laundry reaches the optimal temperature or the minimum temperature required for nursing from the preheating step B2, the time of the subsequent drying step can be greatly shortened.

In the preheating step B2, a section in which either one of the first heater 841 and the second heater 842 is driven simultaneously with the compressor 342 and a section in which only the compressor 342 is driven may be included.

That is, in the preheating step B2, there may be a section in which only the compressor 342 is driven, instead of a section in which the heating unit 340 and the compressor 342 are driven at the same time.

However, it is preferable that only the section for driving the compressor 342 is arranged after the section for driving the heating unit 340 and the compressor 342. If the steam is supplied to the inner case 200 through the heating part 340, not only the temperature inside the inner case 200 but also the temperature of the evaporator 341 rises and the evaporator contacts with moisture, so that a large amount of heat exchange with the refrigerant flowing through the evaporator 341 can be performed. Accordingly, the temperature inside the inner case 200 can be rapidly increased by increasing the performance of the heat supply part 340.

For example, the preheating step B2 may include: a first section in which either one of the first heater 841 and the second heater 842 is driven and the compressor 342 is driven; and a second section in which the driving of the first heater 841 and the second heater 842 is interrupted and only the compressor 342 is driven.

By supplying hot wind and steam to the inner case 200 in the first interval, the temperature inside the inner case 200 and the heat of the air flowing into the circulation duct 320 can be increased.

By supplying hot air into the inner case 200 in the second section, the minimum temperature condition for performing care such as deodorization, wrinkle removal, sterilization, etc. on the laundry can be satisfied.

In the preheating interval B2, the second heater 842 may be driven without driving the first heater 841. Thereby, a larger amount of steam is supplied to the inside of the inner case 200 than when the first heater 841 is driven, and thus the temperature inside the inner case 200 and the heat of the air flowing into the circulation duct 320 can be further increased.

Of course, in the preheating zone B2, the first heater 841 may be driven without driving the second heater 842. Accordingly, in the preheating zone B2, although the temperature of the inner case 200 is not greatly increased, the laundry may be prevented from being damaged by moisture by injecting a small amount of steam. In addition, even when the time for spraying the steam is longer, the temperature rise is not large, so that the time required for sterilization and the like can be further ensured.

The preheating section B2 may be ended if the temperature inside the inner case 200 reaches a reference temperature, or the temperature of the air discharged from the inner case 200 reaches a reference temperature, or the temperature of the refrigerant discharged from the compressor 342 reaches a set temperature. For this, the laundry treating apparatus of the present invention may include a temperature sensor provided inside the inner case 200 or the circulation duct 320, and sensing the temperature of air or the temperature of the refrigerant discharged from the compressor 342.

Of course, in the preheating zone B2, if the temperature of the inside of the inner case 200 increases sharply or the temperature of the refrigerant discharged from the compressor 342 exceeds a reference temperature, the driving of the heating unit 340 may be interrupted.

That is, in the preheating zone B2, either one of the first heating section 841 and the second heating section 842 may be set to be repeatedly driven and interrupted (ON/OFF). Since the purpose of the preheating section B2 is to quickly raise the internal temperature of the inner case 200, the time for driving the first heating section 841 and the second heating section 842 may be set to be longer than the time for stopping the first heating section 841 and the second heating section 842.

If the preheating interval B2 ends, the laundry treating apparatus of the present invention may perform the steam spraying step B3 of formally supplying steam into the inside of the inner case 200. In the steam spraying step B3, a large amount of steam may be supplied to the inner case 200 by simultaneously driving the first heater 841 and the second heater 842. Thereby, the laundry placed in the inner case 200 can increase the moisture content of the entire area by formally receiving the steam in a state of being heated to a prescribed level by the preheating step B2.

The steam injection step B3 may be performed for a shorter time than the existing steam injection step A2. This is because a prescribed level of steam has been supplied in the preheating step B2.

If the steam spraying step B3 is performed, the drying step B6 of drying the laundry using hot air may be directly performed. However, in order to secure the time for the steam sprayed in the steam spraying step B3 to penetrate the whole laundry, a waiting step B4 of waiting for a prescribed time may be performed first.

The waiting step B4 is a state in which the heating part 340 and the compressor 342 are not driven. By the waiting step B4, it is possible to prevent the laundry from being dried before the laundry is completely exposed to the steam, and to prevent the laundry from being damaged by directly supplying the hot wind in a state that the surface temperature of the laundry is increased by the steam.

On the other hand, the drying step B6 is a step of formally supplying hot air to the inner case 200 by driving the compressor 342. Therefore, if hot air is directly supplied in a state where the temperature inside the inner case 200 does not drop below the safe temperature, the temperature inside the inner case 200 may rise above the limit temperature, resulting in damage to laundry.

Accordingly, the cooling step B5 of driving the blower fan 352 may be performed before the drying step B6 is performed. In the cooling step B5, the blower fan 352 may be driven and the driving of the compressor 342 and the heating part 340 may be interrupted.

In the cooling step B5, air inside the inner case 200 may be cooled while circulating along the circulation duct 200.

The laundry treating apparatus of the present invention may perform the drying step B6 of supplying hot wind to the laundry if the temperature inside the inner case 200 drops below a safe temperature or the cooling step B5 is performed for a required time.

The drying step B6 may be performed until the moisture content of the laundry reaches a prescribed level or less. For example, when the drying step B6 is performed in a case where the moisture contained in the laundry is large, the temperature flowing into the circulation duct 320 may be maintained or may not be sharply increased due to the vaporization heat.

However, in the case where most of the laundry is dried, the temperature of the air flowing into the circulation duct 320 may be sharply increased because the vaporization heat is small. In this way, it is possible to secure the dryness of the laundry and to interrupt the driving of the compressor 342 and end the drying step B6 when the minimum time required for nursing passes.

In addition, the laundry treating apparatus of the present invention may end the drying step B6 if the laundry is configured for a minimum time or more above the minimum temperature condition.

The laundry treating apparatus of the present invention can increase the total time for the temperature inside the inner case 200 to be above the minimum temperature condition by further configuring the preheating step B2 before the drying step B6, thereby enabling to greatly reduce the duration of the drying step B6.

On the other hand, in the laundry treating apparatus of the present invention, the compressor 342 may be driven and interrupted on the way in the preheating section B2, and then the state in which the driving of the compressor 342 is interrupted may be maintained until the drying step B6 is performed.

Fig. 27 (a) is a diagram showing the passage of the most basic standard program that the conventional laundry treatment apparatus performs to care for laundry.

In the conventional laundry treating apparatus, the steam preparing step A1 of generating steam by driving the heater may be performed for approximately 2 minutes, and the steam spraying step A2 of spraying the generated steam to the inner case 200 may be performed for approximately 5 minutes. After that, a waiting step A3 of not driving the heating part 340 and the compressor 342 for approximately 5 minutes may be performed, and a cooling step A4 of driving the blower fan 352 for approximately 1 minute may be performed. Thereafter, a drying step A5 of caring for laundry by formally driving the compressor 342 is performed for approximately 26 minutes.

As a result, the existing laundry treatment apparatus can perform a care session of laundry for a total of 39 minutes.

Referring to fig. 27 (B), the laundry treating apparatus of the present invention may perform the steam preparing step B1 of generating steam by driving the heating part 340 for approximately 2 minutes. The total rated capacity of the heating part 340 of the laundry treating apparatus according to the present invention is not different from the rated capacity of the conventional laundry treating apparatus allocated to the heater, and thus the time for boiling water to generate steam may be the same.

In the laundry treating apparatus of the present invention, however, if steam is generated, a preheating step B2 capable of supplying steam into the inside of the inner case 200 by driving only a portion of the heaters of the heating part 340 for about 5 minutes may be performed.

In the preheating step B2, a part of the heaters and compressors in the heating part 340 may be driven at the same time. For example, in the case where the heating part 340 has two heaters, the first heater 841 and the compressor 342 may be driven at the same time.

If the preheating step B2 is finished, a steam spraying step B3 of supplying steam to the inside of the inner case 200 through the heating part 340 for approximately 3 minutes may be performed. That is, since the steam has been supplied in the preheating step B2, the steam spraying step B3 may be allocated less time than the steam spraying step A2 of the existing laundry treating apparatus. In the steam spraying step A2, all heaters of the heating part 340 may be driven. This makes it possible to quickly supply a sufficient amount of steam into the inner case 200. Of course, only a part of the heaters in the heating section 340 may be driven as needed.

On the other hand, in the laundry treating apparatus of the present invention, since the steam spraying step B3 is performed less, the waiting step B4, in which the compressor 342 and the heating part 340 are not driven, may also be performed less. For example, the waiting step B4 may be performed for 4 minutes.

The laundry treatment apparatus of the present invention can similarly perform the cooling step B5 of driving the blower fan 352 for 1 minute

As a result, since the laundry treating apparatus of the present invention also performs the preheating step B2, the drying step B6 of driving the compressor 342 may be performed 2 minutes later than the existing laundry treating apparatus.

However, the laundry treating apparatus of the present invention ensures that the temperature inside the inner case 200 is maintained for a time equal to or longer than the lowest temperature condition where the care effect can be obtained through the preheating step B2, and thus the duration of the drying step B6 can be greatly reduced.

In addition, in the laundry treating apparatus of the present invention, since the internal temperature of the inner case 200 is maintained to be higher than that of the related art in the preheating step B2, the coefficient of performance (COP) of the heat pump becomes high, so that the duration of the drying step B6 can be reduced.

For example, the drying step B6 may be performed for only about 20 minutes.

As a result, the whole standard program of the laundry treatment apparatus of the present invention is executed for 35 minutes, and the time can be reduced as compared with the program execution time of the conventional laundry treatment apparatus. Therefore, not only the energy efficiency is high, but also the time during which the laundry is affected by moisture is reduced, so that the durability of the laundry can be further ensured.

Fig. 28 (a) is a diagram showing a conventional laundry treatment apparatus performing a sterilization process.

If the conventional laundry treating apparatus performs the sterilization process, the steam preparing step C1, the steam spraying step C3, the waiting step C4, the cooling step C4, and the drying step C5 may be performed as in the standard process.

Microorganisms, bacteria, and the like need to be sterilized for a sterilization time (e.g., 25 minutes or more) at a sterilization temperature (e.g., 55 degrees or more) or more.

On the other hand, although sterilization can be performed by supplying hot air in the drying step c5, the drying step c5 aims at drying laundry, not at maintaining the surface temperature of the laundry at a sterilization temperature or higher, and thus the surface temperature of the laundry cannot be maintained at the sterilization temperature or higher due to the vaporization heat of moisture.

Accordingly, the conventional laundry treating apparatus may perform the sterilization step c2 of sterilizing before the steam spraying step c 3.

In the conventional laundry treating apparatus, in the sterilization step c2, the internal temperature of the inner case 200 may be made to be equal to or higher than the sterilization temperature for a time equal to or longer than the sterilization time by driving the compressor.

However, at the beginning of the process, the temperature inside the inner case 200 is low, and therefore, a sufficient amount of heat exchange cannot be performed in the evaporator, resulting in a decrease in the coefficient of performance of the heat pump. In addition, since the inside of the inner case 200 is in a dried state, the temperature may be rapidly changed by the supply of hot air.

Accordingly, in the conventional laundry treatment apparatus, the compressor needs to be driven for a longer time in order to reach the sterilization temperature in the sterilization step c2, and the temperature inside the inner case 200 increases sharply when the compressor is driven, so that it is necessary to repeatedly interrupt the driving of the compressor at any time and then to drive again, so as to prevent the laundry from being heated.

As a result, the sterilization step of the conventional laundry treatment apparatus requires a long time, that is, about 45 minutes.

Fig. 28 (b) is a diagram showing an execution mode of a sterilization program of the laundry treatment apparatus of the present invention.

If the laundry treating apparatus of the present invention performs the sterilization process, the steam preparing step D1, the steam spraying step D3, the waiting step D4, the cooling step D5, and the drying step D6 may be performed in the same manner as the operation of the compressor, the heater, and the blower fan as in the standard process.

The laundry treating apparatus of the present invention may also perform the sterilization step D2 before the steam spraying step D3 in order to maintain the surface of the laundry at a sterilization temperature or higher during the sterilization time.

In the sterilization step D2 of the laundry treating apparatus of the present invention, the heating part 340 and the compressor 342 may be driven at the same time.

Specifically, in the sterilization step D2, the laundry treating apparatus of the present invention may simultaneously drive either one of the first heating part 341 and the second heating part 342 and the compressor 342.

Thus, the laundry treating apparatus of the present invention can raise the temperature inside the inner case 200 by supplying a relatively small amount of steam, and can prevent the surface of the laundry from excessively containing moisture. As a result, the surface of the laundry can be easily raised above the sterilization temperature by driving the compressor 342 to supply hot air.

In addition, the rate of temperature increase inside the inner case 200 can be reduced by increasing the specific heat inside the inner case 200 by a small amount of the steam. Therefore, even if the overall average temperature increases when the compressor 342 is driven, the temperature increase rate can be low, and even if the driving of the compressor 342 is interrupted, the temperature decrease rate can be low.

Therefore, the laundry treating apparatus according to the present invention can greatly reduce the time for stopping the driving of the compressor 342 and the number of times of re-driving after stopping the driving of the compressor because it is very easy to maintain the temperature inside the inner case 200 at or above the sterilization temperature.

Further, by the ON/OFF (ON/OFF) of the heating part 340, the internal temperature of the inner case 200 can be finely controlled.

Accordingly, the laundry treating apparatus of the present invention can more quickly reach the sterilization time of maintaining the sterilization temperature or more in the sterilization step B2, so that the duration of the sterilization step B2 can be greatly reduced.

On the other hand, in the sterilization step B2, it may be more advantageous to use the first heating section 841 having a lower power consumption than the second heating section 842. This is because the amount of steam supplied to the inner case 200 when the first heating part 841 is driven is smaller than when the second heating part 842 is driven, so that the temperature inside the inner case 200 can be more slowly increased and the temperature inside the inner case 200 can be more easily maintained.

In addition, since a small amount of steam is supplied when the first heating part 841 is driven, the moisture content of the surface of the laundry may not be greatly increased. Therefore, driving the first heating part 841 can more easily maintain the surface temperature of the laundry to be equal to or higher than the sterilization temperature than driving the second heating part 842, because the heat of vaporization heat-induced loss can be minimized even if hot air is supplied to the laundry.

In addition, in the laundry treating apparatus of the present invention, since it is more important to maintain the sterilization temperature level during the sterilization time than to raise the internal temperature of the inner case 200, it is more advantageous to drive the first heating part 841, which generates less steam, for sterilization conditions.

As a result, in the laundry treating apparatus of the present invention, the heating part 340 may divide the maximum heater capacity to drive the heater, and may also adjust the amount of steam, so that the duration of the sterilization step B2 can be greatly reduced.

For example, in the laundry treating apparatus of the present invention, the sterilization step B2 may be completed in about 28 minutes. As a result, the duration of the entire sterilization process can be reduced, and more energy can be saved.

The clothes are easy to deform or damage due to moisture and high temperature.

In order to care clothes in a dry state, a conventional clothes treating apparatus needs to make the clothes contain moisture at a predetermined level or more. Accordingly, the rated capacity of the heater of the existing laundry treating apparatus is determined to supply a large amount of steam to the heating part 340. As a result, the conventional laundry treatment apparatus has a limitation that such laundry susceptible to moisture and high temperature cannot be treated at all.

However, in the laundry treating apparatus of the present invention, since the heating part 340 has a plurality of heaters sharing the maximum heater power, the amount of supplied steam and the rate of temperature rise inside the inner case 200 at the time of steam injection can be controlled.

Therefore, even such laundry susceptible to moisture and high temperature can be treated by the laundry treatment apparatus of the present invention.

The display panel of the laundry machine according to the present invention may be provided with an input unit for inputting instructions or information to the control unit 700. The input part may be configured to be able to receive fragile information indicating that the laundry received inside the inner case 200 is laundry susceptible to moisture or high temperature.

For example, the input may receive the frangible information through input of the type or material of the garment or selection of the type or material of the garment provided by the manufacturer.

As another example, the input may receive the fragile information by selecting a program such as a cashmere program or a silk program to match with fragile clothing.

The laundry treating apparatus of the present invention may omit a preheating step of simultaneously driving the heating part and the compressor after the steam preparing step if the fragile information is inputted.

Thus, the laundry treating apparatus of the present invention can prevent laundry damage caused by a temperature rise inside the inner case 200 or laundry damage caused by a humidity rise inside the inner case 200 by omitting the preheating step.

In addition, the laundry treating apparatus of the present invention may drive only one heater of the first heater 841 and the second heater 842 in the steam spraying step after the preheating step. Thereby, in the steam spraying step, the laundry may be prevented from being exposed to moisture by minimizing the amount of steam supplied into the inside of the inner case 200.

After that, the waiting step, the cooling step, and the drying step may be performed.

In addition, the laundry treating apparatus of the present invention may perform an additional cooling step of additionally driving only the blower fan 352 after the drying step. Accordingly, even the laundry slightly exposed to the hot wind and the steam can be prevented from being damaged by the residual heat or the residual moisture before the laundry is drawn out from the inside of the inner case 200 by cooling.

For example, the frangible information may comprise cashmere information that includes a cashmere material for at least a portion of the garment.

For example, the cashmere information may correspond to receiving the cashmere program.

If the cashmere program is executed, the laundry treating device of the present invention may perform the steam preparing step E1 of heating water by driving all the heating parts 340.

In the case where the heating unit 340 includes the first heating unit 841 and the second heating unit 842, the first heating unit 841 and the second heating unit 842 may be driven at the same time in the steam preparing step E1.

If the steam preparing step E1 is finished, the laundry treating apparatus of the present invention may omit the preheating step and directly perform the steam spraying step E2. At this time, the steam spraying step E2 may perform the reduced spraying step E2 of driving only any one of the first heating part 841 and the second heating part 842.

Although the cashmere material is easily affected by moisture, a predetermined level of moisture is required during nursing, and thus the reduced spraying step E2 may be equivalent to driving only the second heating portion 842.

Therefore, the steam supply amount in the reduced spraying step E2 may be smaller than that in the spraying step in the standard program or the sterilization program.

Thereafter, if the reduced spraying step E2 is finished, a waiting step E3 of interrupting the driving of the compressor 342 and the heating part 340, a cooling step E4 of driving the blowing fan 352, and a drying step E5 of caring for laundry by driving the compressor 342 may be performed.

At this time, if the drying step E5 is completed, an additional cooling step E6 of driving the blower fan 352 may be performed.

On the other hand, the duration of the reduced spraying step E2 in the cashmere program may be shorter than the duration of the steam spraying step of the standard program, the sterilization program, etc.

In addition, the duration of the drying step E5 in the cashmere process may be shorter than that of the drying step of the standard process, the sterilization process, and the like.

Thereby, the exposure of moisture and heat to the laundry can be minimized, and even the fragile laundry such as cashmere can be performed with care including deodorization, wrinkle removal, foreign matter separation, drying, and the like.

Among fragile clothes, materials such as silk are very susceptible to moisture. Therefore, delicate clothing such as silk needs to be managed more carefully.

The frangible information may comprise silk information that at least a portion of the garment comprises silk material.

For example, the silk information can correspond to receiving the silk procedure.

If the silk process is performed, the laundry treating apparatus of the present invention may perform the steam preparing step F1 of heating water by driving all the heating parts 340.

In the case where the heating unit 340 includes the first heating unit 841 and the second heating unit 842, the first heating unit 841 and the second heating unit 842 may be driven at the same time in the steam preparing step F1.

If the steam preparing step F1 is finished, the laundry treating apparatus of the present invention may omit the preheating step and directly perform the steam spraying step F2. At this time, the steam spraying step F2 may perform the minimum spraying step F2 of driving only any one of the first heating part 841 and the second heating part 842.

Since the silk material is very susceptible to moisture, it is only necessary to maintain a minimum humidity at which wrinkles can be removed. Therefore, the minimum spraying step F2 may correspond to driving only the first heating portion 842.

Therefore, the steam supply amount of the minimum spraying step E2 may be minimum compared to the spraying steps of the standard program or the sterilization program, the cashmere program.

On the other hand, in the silk procedure, the spraying step F2 may also be omitted entirely. That is, the steam may not be supplied to the inside of the inner case 200.

Thereafter, if the minimum spraying step F2 ends, a waiting step F3 of interrupting the driving of the compressor 342 and the heating part 340, a cooling step F4 of driving the blowing fan 352, and a drying step F of caring for laundry by driving the compressor 342 may be performed.

At this time, if the drying step F5 is completed, an additional cooling step F6 of driving the blower fan 352 may be performed.

On the other hand, the duration of the minimum spraying step E2 of the silk process may be shorter than the duration of the steam spraying step of the standard process, the sterilization process, the cashmere process, etc.

In addition, the duration of the drying step E5 of the silk process may be shorter than that of the drying step of a standard process, a sterilization process, etc.

Thus, the exposure of moisture and heat to the laundry can be minimized, and thus even the fragile laundry such as silk can perform care including deodorization, wrinkle removal, foreign matter separation, drying, and the like.
