Description

Clothing treatment device and control method of clothing treatment device {Laundry Treatment Apparatus And Control Method Thereof}

The present invention relates to an apparatus for treating clothes having a function of drying clothes or bedding.

The clothing processing device refers to all devices that manage or process clothing, such as washing, drying, or removing wrinkles, such as laundry or bedding in a home or a laundry place. The clothes processing apparatus includes a washing machine, a dryer, a washing machine and a dryer, and the like.

A washing machine is a device for washing clothes or bedding, and a dryer is a device for removing moisture such as clothes or bedding and drying it. The washing machine and dryer is a device that combines the washing and drying functions.

In particular, the dryer evaporates moisture contained in the object to be treated by supplying hot air to the object to be treated, such as clothes or bedding, which is introduced into a drum (or tub). The water to be evaporated from the drum to be evaporated and the air exiting the drum retains moisture from the object to be subjected to high temperature and high humidity. At this time, the type of the dryer is classified into a condensation type and an exhaust type according to a method of treating this high temperature and humid air.

The condensation dryer does not discharge hot and humid air to the outside, and condenses moisture contained in the hot and humid air through heat exchange while circulating. On the other hand, the exhaust-type dryer directly discharges hot and humid air to the outside. The condensation type dryer has a structure for treating condensed water, and the exhaust type dryer has a structural difference from each other in that it has a structure for exhausting air.

The condensation dryer is provided with the duct to remove moisture from the air discharged from the drum and then heat it to flow into the drum. Conventionally, a circulation fan is disposed on the duct perpendicular to the evaporator in front of the evaporator, and thus a large flow resistance occurs, and there is a problem in that heat exchange efficiency is low because flow does not flow uniformly into the evaporator. To solve this, it is necessary to simplify the duct, and it is necessary to optimize the layout of various parts on the base cabinet.

In addition, in the case of a condensation dryer using a heat pump, as the amount of laundry to be dried increases, the amount of heat exchange between the condenser and the evaporator corresponding to the first heat exchanger and the second heat exchanger is also important, but the refrigerant is compressed and sent out. The capacity of the compressor is also important. In order to efficiently use the space inside the cabinet, the capacity of the compressor should not be increased largely depending on the amount of laundry to be dried, but the temperature of the compressor should not be too high in order to derive maximum performance from the limited compressor capacity. This is because the increase in the internal temperature of the compressor decreases the refrigerant compression efficiency of the compressor. Therefore, there is a need for a method for cooling the temperature of the compressor when it rises more than necessary.

The first object of the present invention is an apparatus for cooling a compressor and a control method of the apparatus in order to maximize the performance of the compressor. That is, if there is a lot of laundry to be dried, the load on the compressor increases, so the compressor temperature rises, and when the compression efficiency of the refrigerant decreases, the performance of the compressor deteriorates. Therefore, a cooling device and a control method for maintaining the compressor temperature at a certain level To provide.

Hot dry air is supplied to the interior of the drum 1030 through the inlet 1050a.

Since the drum 1030 and the connecting duct 1230 are spaced apart from each other along the vertical direction, the inlet duct 1220 is the drum from the connecting duct 1230 disposed below the drum 1030 ( 1030). The inlet duct 1220 may be extended in the vertical direction like the outlet duct 1210, but due to the connection structure, the length of the inlet duct 1220 extending in the vertical direction is longer than that of the outlet duct 1210.

FIG. 3 is a perspective view showing the base cabinet 1310 and main parts mounted on the base cabinet 1310 shown in FIG. 1, and FIG. 4 is a plan view of the base cabinet 1310 shown in FIG. 3.

3 to 4, the base cabinet 1310 is provided under the drum 1030 to provide a space in which various components are mounted, including the heat pump cycle devices 1100. The bottom surface of the base cabinet 1310 may form the bottom surface of the clothing processing apparatus 1000.

A drum motor mounting portion 1314, a compressor mounting portion 1315, a base flow path portion 1310a, and a condensate recovery portion 1316 are formed in the base cabinet 1310. The drum motor mounting portion 1314 and the compressor mounting portion 1315 are disposed on one side of the base flow path portion 1310a.

In this embodiment, the drum motor It is shown that the mounting portion 1314 and the compressor mounting portion 1315 are respectively disposed at the left front and rear sides of the base flow path portion 1310a. A drum motor 1800 that generates a driving force for rotation of the drum 1030 is mounted on the drum motor mounting unit 1314. A belt (not shown) for transmitting the driving force of the drum motor 1800 to the drum 1030 may be connected to the drum motor 1800. The belt is arranged to surround the outer periphery of the drum 1030.

A pulley 1810 and a spring (not shown) may be used to adjust the tension applied to the belt. The pulley 1810 may be configured to apply a certain tension to the belt. The pulley 1810 is configured to be rotatable on a bracket (not shown) mounted on the drum motor mounting portion 1314 or the drum motor mounting portion 1314.

In order to adjust the tension of the belt, the drum motor 1800 may be configured to be rotated within a certain angular range about one axis, and then reverted to the initial position by the elastic force of the spring. To this end, the drum motor 1800 is configured to be rotatable about one axis on the drum motor mounting portion 1314, and the spring may be connected to the drum motor mounting portion 1314 and the drum motor 1800, respectively. . A blower fan 1820 may be mounted on the shaft of the drum motor 1800.

In this embodiment, it is shown that the belt is connected to the shaft provided on one side of the drum motor 1800, and the blowing fan 1820 is mounted on the shaft provided on the other side of the drum motor 1800.

The shafts provided on both sides of the drum motor 1800 are rotated in the same direction and at the same speed. If two shafts are provided in one driving motor, it has many advantages in terms of improving power consumption of the clothing processing apparatus 1000. Basically, compared to the case where the driving motor for rotating the drum 1030 and the driving motor for rotating the blower fan 1820 are respectively provided, power consumption is reduced by half.

In particular, the time point at which the blowing fan 1820 needs to rotate is the same as the time point at which the drum 1030 rotates. This is because hot and dry air is supplied to the drum 1030 while the drum 1030 is rotating, and hot and humid air may leak from the drum 1030. Accordingly, a state in which rotation of any one of the drum 1030 and the blower fan 1820 is unnecessary does not occur.

In this embodiment, the blowing fan 1820 is composed of an axial flow fan, showing that it is configured to blow air toward the front of the cabinet 1010. However, the present invention is not necessarily limited thereto. For example, the blower fan 1820 may be configured as a sirocco fan. The blowing fan 1820 is rotated according to the driving of the drum motor 1800, and is configured to blow air in an interior space between the cabinet 1010 and the drum 1030. Therefore, the air leaked into the gap between the drum 1030 and the front supporter 1040, and the gap between the drum 1030 and the rear supporter 1050 is fine by the blowing fan 1820. The inner space flows. Therefore, the occurrence of condensation caused by stagnant air can be reduced.

Meanwhile, a heat radiating fan (not shown) may be mounted on the circuit board constituting the control unit. The heat dissipation fan forms a circulating flow that circulates air in an interior space between the cabinet 1010 and the drum 1030 together with the blower fan 1820 while dissipating elements mounted on the circuit board. The heat dissipation fan is located above the base flow path portion 1310a, and may be configured to blow air downward, that is, toward the base flow path portion 1310a.

The heat dissipation fan is disposed on the opposite side of the blower fan 1820 based on the center of the drum 1030 to form a circulation flow surrounding the drum 1030 together with the blower fan 1820. For example, the blowing fan 1820 may be disposed in the lower left of the drum 1030, and an exhaust fan 1730 may be disposed in the upper right of the drum 1030. The heat dissipation fan is installed in the cabinet 1010, and is configured to discharge air in a space between the cabinet 1010 and the drum 1030 to the outside. That is, the air leaked from the drum 1030 is exhausted to the outside while continuously flowing by the blowing fan 1820 and the heat dissipation fan (not shown). The exhaust fan 1730 may be located behind the heat radiation fan. In this embodiment, it is shown that the exhaust fan 1730 is installed on the rear wall of the cabinet 1010 located behind the heat radiation fan.

The compressor 1120 that generates compressed air for heat exchange is mounted on the compressor mounting unit 1315. The compressor 1120 is an element constituting the heat pump cycle devices 1100, but does not need to be installed in the base flow path portion 1310a because it does not directly exchange heat with air. Rather, if the compressor 1120 is installed in the base flow path portion 1310a, air flow may be prevented, so the compressor 1120 is preferably installed outside the base flow path portion 1310a.

A gas-liquid separator 1140 is installed on the upstream side of the compressor 1120. The gas-liquid separator 1140 separates the refrigerant flowing into the compressor 1120 into a gas phase and a liquid phase, so that only the gas phase refrigerant flows into the compressor 1120. According to this, a problem in which a liquid refrigerant flows into the compressor 1120 and causes a malfunction or a decrease in efficiency may be prevented.

The compressor mounting portion 1315 is provided with at least three fixing ribs 1315a for fixing the compressor 1120. To reduce vibration, the fixed rib 1315a may be formed to extend through the compressor mounting portion 1315 to the rear surface. The fixed rib 1315a formed to extend to the rear surface is configured not to contact the bottom surface. The compressor mounting portion 1315 may be provided with a support rib 1315b for supporting the compressor 1120. The support rib 1315b may be formed of a combination of a portion extending radially from the center of a virtual polygon formed by connecting a plurality of fixed ribs 1315a and concentric circles with respect to the center.

The compressor cooling fan 1720 may be installed adjacent to the compressor 1120. The compressor cooling fan 1720 is configured to generate wind or blow air around the compressor 1120 toward the compressor 1120. The temperature of the compressor 1120 may be lowered by the compressor cooling fan 1720, and as a result, compression efficiency may be improved. In this embodiment, it is shown that the compressor cooling fan 1720 is installed on the rear wall of the cabinet 1010 located at the rear of the compressor 1120.

The compressor cooling fan 1720 is used to cool the compressor temperature so that the compressor 1120 can be operated at an appropriate temperature. However, when the temperature rises due to the heated air inside the cabinet 1010, the compressor cooling fan 1720 has a limitation in cooling the compressor, so the compressor cooling fan is operated to cool the compressor for relatively cold external air. An opening 1070b penetrating the cabinet and the rear cover may be provided at a position corresponding to a virtual projection surface projected on the cover.

The cabinet opening is generally provided in the rear cover behind the drum 1030 so that external air can be introduced through the rear cover. The size of the opening 1070b is provided in a rectangular shape larger than the shape of the compressor cooling fan 1720 so that the compressor cooling fan 1720 can be pulled out when separated, and one edge may be provided in a concave rounded rectangular shape. have. Specifically, the height of the compressor cooling fan 1720 and the width of the cap cover 1090 are larger than the width of the compressor cooling fan 1720, and one of the upper corners of the rectangle is of the rear supporter 1150. In order to prevent interference due to the round shape, it may be provided in a shape that is concavely rounded inward. The control method of the compressor cooling fan 1720 will be described later.

The base flow path part 1310a forms a part of the duct 1200. Based on the flow of air, the base flow path portion 1310a is divided into the guide portion 1311, the heat exchange portion 1312, and the circulation fan accommodating portion 1313. The evaporator 1110 and the condenser 1130 are disposed in the heat exchange part 1312, and the circulation fan 1710 is disposed to face the condenser 1130 in the circulation fan accommodating part 1313.

The guide portion 1311 corresponds to a portion through which the air discharged from the front opening 1030a of the drum 1030 flows. An opening opened upward is formed in the guide portion 1311, and the opening communicates with an exhaust port 1040a of the front duct connector 1210. The air flowing downward through the front duct connector 1210 is switched from the guide portion 1311 toward the rear of the base cabinet 1310 and flows into the heat exchange portion 1312.

The heat exchange unit 1312 corresponds to a portion in which the evaporator 1110 for removing moisture from the air introduced from the guide unit 1311 and the condenser 1130 for heating the air from which moisture is removed are installed. The heat exchange part 1312 may extend in a straight line from front to rear of the base cabinet 1310. The refrigerant compressed in the compressor 1120 becomes a high temperature and high pressure state and flows to the condenser 1130. In the condenser 1130, the refrigerant is liquefied while releasing heat. The liquefied high pressure refrigerant is decompressed in an expander (not shown). The low-temperature, low-pressure liquid refrigerant enters the evaporator 1110.

The circulation fan accommodating portion 1313 corresponds to a portion in which the circulation fan 1710 for sucking and blowing air passing through the heat exchange portion 1312 is accommodated. The circulation fan 1710 is disposed such that the rotating shaft faces the condenser 1130 and the evaporator 1110, and is composed of a sirocco fan blowing air in front, that is, the heated air passing through the condenser 1130 to the side. do.

The hot and dry air that has passed through the condenser 1130 is supplied to the drum 1030 through the rear duct connector 1220 through the blowing fan 1820 receiving portion. The high temperature dry air supplied to the drum 1030 evaporates the moisture of the object to be treated and becomes high temperature and high humidity air. The hot and humid air is recovered through the front duct connector 1210, and heat exchanges with the refrigerant in the evaporator 1110 to become low temperature air. At this time, as the temperature of the air decreases, the amount of saturated water vapor in the air decreases, and moisture contained in the air condenses. Subsequently, the low-temperature dry air is heat-exchanged with the refrigerant in the condenser 1130 to become high-temperature dry air and is supplied to the drum 1030 again.

The evaporator 1110, the condenser 1130, and the circulation fan 1710 mounted on the base flow path part 1310a are eccentrically positioned from the center of the base cabinet 1310 to one side. That is, the flow path after the guide portion 1311 in the base flow path portion 1310a extends toward the rear at a position eccentric from the center of the base cabinet 1310 to one side. A condensate recovery part 1316 is provided between the base flow passage part 1310a and the compressor mounting part 1315. The condensate recovery unit 1316 communicates with the base flow path unit 1310a to form a space in which condensate generated in the evaporator 1110 is recovered. In this embodiment, it is shown that the condensate recovery unit 1316 is configured to communicate with the heat exchange unit 1312.

FIG. 5 is a conceptual view showing the structure behind the drum 1030 shown in FIG. 1, and FIG. 6 is a conceptual view showing the main parts behind the drum 1030 shown in FIG. 6 separately. 5 or 6, a support ring 1051 of the drum corresponding to the rear opening 1030b of the drum is protruded on the front surface of the rear supporter 1050 facing the drum 1030. . The support ring 1051 of the drum is inserted into the rear opening 1030b of the drum to support the drum 1030 to rotate.

At least two or more rollers 1060 are rotatably mounted on the rear supporter 1050. The roller 1060 rotatably supports the drum 1030 under the drum 1030.

A sealing pad (not shown) may be disposed to cover the connection portion to prevent air leakage through the gap between the rear opening 1030b of the drum 1030 and the support ring 1051 of the drum. . The sealing pad is formed to cover and cover the rear opening 1030b of the drum and the support ring 1051 of the drum. The sealing pad may be formed of a felt material.

The rear supporter 1050 is formed with an inlet 1050a corresponding to the rear opening 1030b of the drum. The inlet 1050a may be formed at a position eccentric to one side based on a vertical reference line passing through the center of the rear supporter 1050. In addition, the inlet 1050a may be formed above a horizontal reference line passing through the center of the rear supporter 1050.

The rear supporter 1050 is equipped with the rear duct connector 1220 that connects the inlet 1050a spaced up and down and the outlet 1313b of the circulation fan receiving portion. The rear duct connector 1220 is formed to extend upward, and is configured to guide air blown by the circulation fan 1710 to the inlet 1050a of the rear supporter 1050.

The rear duct connector 1220 may be screwed or hooked to the rear surface of the rear supporter 1050 and the circulation fan accommodating portion 1313. In this embodiment, it is shown that the rear duct connector 1220 is hooked to the circulation fan accommodating portion 1313, and screwed to the rear of the rear supporter 1050.

In the rear supporter 1050, a rear protrusion 1050b may be formed at a portion where the rear duct connector 1220 is not disposed. Accordingly, the front surface of the rear supporter 1050 may have a relatively recessed shape toward the rear. Therefore, the internal space of the drum 1030 may be further secured. The rear duct connector 1220 is formed with a first opening (not shown) communicating with the outlet 1313b of the circulation fan accommodating part and a second opening 1220a communicating with the inlet 1050a of the rear supporter 1050. do. The first opening is opened downward at the lower end of the rear duct connector 1220 and is disposed to face the outlet 1313b. The second opening 1220a is positioned above the first opening, and is opened to face the inlet 1050a of the rear supporter 1050.

The interior of the rear duct connector 1220 is provided with an internal partition 1221a for reducing vortex and resistance of air flowing inside the rear duct. This will be described later. The rear duct connector 1220 may include a base member 1221 forming a rear portion and a cover member 1222 forming a front portion. The cover member 1222 may be screwed or hooked to the base member 1221.

The first opening may be defined by a combination of the base member 1221 and the cover member 1222. In this embodiment, when the cover member 1222 is coupled to the base member 1221, it is shown that the inner surface of the cover member 1222 defines one side of the first opening. The second opening 1220a may be formed on the front surface of the cover member 1222. The base member 1221 may be provided with an inner partition 1221a, and a portion of the inner partition 1221a may be exposed forward through the second opening 1220a. .

The rear cover 1070 is disposed to cover the rear duct connector 1220. The inner surface of the rear cover 1070 may include a recessed portion 1070a recessed toward the outer surface. The protrusion 1050b and the rear duct connector 1220 of the rear supporter are accommodated in the recess 1070a. The rear supporter 1050 is mounted on the rear cover 1070. Further, at the lower portion of the rear cover 1070, the opening through which the outside air can be introduced through the cabinet to a virtual projection surface generated when the compressor cooling fan is projected to the rear cover 1070 assembled in the cabinet ( 1070b).

The base member 1221 is divided into a first part (not shown) extending upward from the first opening, and a second part (not shown) positioned above the first part and corresponding to the second opening 1220a. Can. Since the second portion is formed to have a wider width than the first portion, vortices may occur when air flows from the narrow first portion to the wider second portion, thereby generating flow resistance. . To solve this, the base member 1221 is formed with the inner partition 1221a that guides the flow of air so that air can flow more naturally from the first portion to the second portion. A part of the inner partition 1221a is exposed forward through the second opening 1220a. When the cover member 1222 is coupled to the base member 1221, the inner partition 1221a contacts the inner surface of the cover member or is disposed adjacent to the inner surface of the cover member.

The inner partition wall 1221a extends upward from one inner wall of the base member 1221. Specifically, since the width of the second portion is wider than the first portion, the inner wall of one side of the base member 1221 extends outward at a point corresponding to the upper end of the first portion. That is, the inner partition wall 1221a extends upward at a position inside or adjacent to the inner wall of the base member 1221 where the shape change occurs.

The inner partition 1221a is formed to be inclined in the same direction as one side inner wall, and guides air to flow naturally from the first portion to the second portion. The inner partition 1221a may be disposed to be inclined upward from one inner wall of the base member 1221 toward the other inner wall.

Meanwhile, a case where condensed water flows into the rear duct connector 1220 by blowing the circulation fan 1710 may occur. However, unlike air, condensate does not overcome gravity and falls. For smooth drainage of condensate, a drain hole (not shown) for preventing water accumulation may be formed between one inner wall of the base member 1221 and the inner partition 1221a. For example, the lower end of the inner partition wall 1221a may be spaced apart from one inner wall of the base member 1221 to form the drain hole, but the present invention is not limited thereto. That is, the inner partition wall 1221a is branched from one inner wall of the base member 1221. In the form Although extended, a drain hole (not shown) is formed at the bottom of the inner partition wall 1221a to be configured to drain condensate.

Meanwhile, a rounded round portion 1221b may be formed at an upper end of the inner partition wall 1221a toward one side. In FIG. 6, the round portion 1221b is formed to be rounded in a direction opposite to the extending direction of the inner partition 1221a. According to this, the air naturally flows in the opposite direction from the top of the inner partition 1221a, so that vortex and flow resistance can be reduced.

On the inner surface of the cover member 1222 defining the second opening 1220a, ribs (not shown) are arranged to be spaced apart at regular intervals to reinforce the strength around the second opening 1220a. The rib (not shown) may be formed to extend toward the second opening 1220a.

An engaging hook (not shown) is formed on the base member 1221, and an engaging hole (not shown) is formed on the cover member 1222 so that an engaging hook (not shown) can be engaged. May be spaced apart at regular intervals along the circumference of the base member 1221. The cover member 1222 may be coupled to the base member 1221 by engaging hooks between the hook and the hook.

Referring to FIG. 7, the garment processing device prevents foreign substances due to the opening 1070b from entering the cabinet 1010 and blocks noise as much as possible, while detaching and attaching the external air to the rear cover. Possible cap cover 1090 may be included. When the cap cover 1090 is engaged with the rear cover 1070, it protrudes rearward, and extends from the cap cover rear surface 1096 and the cap cover rear surface 1096 forming the rear surface of the cap cover 1090. A cap cover side 1093 which becomes a side surface of the cap cover 1090; And a cap cover flange 1092 that is bent and extended at one end that is not connected to the cap cover rear surface 1096 among both ends of the cap cover side, and the cap cover flange 1092 is coupled to the opening 1070b The opening 1070b may be covered, and air may flow in, but noise may be suppressed and foreign substances may be prevented.

As a specific shape, the height of the cap cover 1090 is the height of the compressor cooling fan 1720 and the width of the cap cover 1090 is larger than the width of the compressor cooling fan 1720, and among the upper corners of the rectangle One may be provided in a round shape inward due to the round shape of the rear supporter 1150.

Especially, The cap cover rear surface 1096 has at least one cap cover communication hole 1095a through the cap cover rear surface 1096 through which external air can be introduced, and the cap cover communication hole 1095a is rectangular in shape Both short sides have a round shape. This is a shape similar to a symbol indicating the end and start of a signal, which is one of the promised symbols in a flow chart. The cap cover communication hole may include a cap cover louver 1097 having a louver shape rather than a simple through shape to prevent rainwater from entering the outside. When the cap cover louver 1097 and the rear cover 1070 are assembled and coupled to the cabinet 1010, the cap cover louver 1097 protrudes forward and faces downward, so that the louver communication hole 1095b is When facing upward, or when the cap cover louver 1097 protrudes rearward, it is directed upward and the louver communication hole 1095b may be directed downward. This is to prevent external rainwater from entering. Preferably, in order to block compressor noise as much as possible, the cap cover louver 1097 protrudes forward and faces downward, that is, the louver communication hole 1095b can face upward. In this case, the outside air is guided upward through the louver shape after passing through the cap cover communication hole 1095a and flows into the cabinet 1010 in an upward direction when passing through the louver communication hole 1095b.

Further, a virtual projection surface projecting the compressor cooling fan 1720 to the rear surface of the cap cover may include a compressor 1120 and a sound insulating portion 1091 for blocking noise of the compressor cooling fan 1720. . The sound insulating portion may be made of a sound insulating material or a sound absorbing material capable of blocking noise. In addition, the cap cover communication hole 1095a and the cap cover louver 1097 may be provided on the cap cover rear surface 1096 in an area other than a virtual projection surface projected on the rear surface of the cap cover. This induces the inflow of air to the compressor cooling fan 1720 for cooling the compressor 1120, and the noise generated by the compressor 1120 and the compressor cooling fan 1720 is immediately followed by the sound insulation portion 1091. It is blocked so as to escape through the cap cover communication hole (1095a) and the louver communication hole (1095b) without sound insulation. This has an effect that can reduce noise than the case where the cap cover communication hole 1095a and the louver communication hole 1095b are placed immediately behind the compressor cooling fan 1720. Preferably, at least one base through hole (not shown) penetrating the base cabinet is provided below the compressor mounting portion 1315 of the base cabinet, and the compressor cooling fan 1720 can be installed in the base through hole. .

In order to facilitate the assembly of the cap cover 1090 with the rear cover 1070, a part of the cap cover flange 1092 is further extended, and the cap cover flange 1092 is provided below the cap cover 1090. At least one cap cover having at least one cap cover fixing tab 1098 having a protruding square shape, or at least one cap cover protruding from the cap cover flange on the upper side of the cap cover and having a circular cap cover screw hole 1099a A skew-like fastening portion 1099 may be provided.

In addition, a partition wall (not shown) for distinguishing between the region provided with the sound insulation portion 1091 and the region provided with the cap cover communication hole may be further included for the above-described noise isolation. The partition wall may be made of a sound insulation material, or may be made of a metal used to make the cap cover 1090 and then affixed to the partition wall.

The material of the cap cover 1090 is metal, which may vary depending on the use environment. Preferably, the shape is completed through press processing and louver processing on one metal plate, and the end of the cap cover flange 1092 can be processed to be folded inside to bend to remove sharp edges during metal processing, in which case it is not folded The cap cover fixing tab 1098 or the cap cover cue fastening portion 1099 may be thinner than a double thickness by folding the cap cover flange.

8 relates to a method for controlling the compressor cooling fan 1720. As shown in Figure 3, after the start of the operation of the compressor 1120 (step S10), the temperature using the temperature sensor 1610 to measure the internal temperature (hereinafter referred to as the compressor temperature) of the compressor 1120 machine Through the measuring step (compressor temperature measuring step, step S20) may transmit a control signal for the measured temperature to the control unit 1600. When receiving the control signal for the temperature, the controller 1600 compares with a preset reference temperature (step S30), and when the temperature of the compressor 1120 is less than the reference temperature, when the operation of the compressor cooling fan 1720 is stopped If the temperature of the kicker (compressor cooling fan termination step, step S32) and the compressor 1120 is higher than the reference temperature, the compressor cooling fan 1720 may be operated (compressor cooling fan operation step, step S31). That is, the control method may be controlled by comparing the preset reference temperature with the measured compressor temperature to turn the compressor cooling fan 1710 on/off. The control method includes the temperature measurement step (step S20) while the compressor 1120 is operating; The compressor cooling fan operation step (step S31) and the compressor termination step (S32) are repeated every time (step S33). If the compressor 1120 does not operate, the compressor cooling fan 1720 is terminated (step S40). The compressor temperature may directly measure the internal temperature of the compressor 1120 or may be compressed and measured by measuring the temperature of the refrigerant immediately after discharge. Preferably, by measuring the temperature when the refrigerant compressed and discharged from the compressor 1120 flows along the refrigerant pipe directly connected to the compressor, the internal temperature of the compressor is estimated and used.

As the temperature sensor, various methods such as an infrared temperature sensor and a laser temperature sensor can be used, but preferably, a thermistor is installed in the refrigerant pipe to measure the temperature of the discharged refrigerant.

9 is another embodiment for controlling the compressor cooling fan 1720. Apart from such simple on/off control as shown in FIG. 8, an inverter method can be variably changed by using an inverter method for the compressor cooling fan to maintain the optimum compressor temperature. That is, when the internal temperature of the compressor 1120 (hereinafter, referred to as the compressor temperature) is equal to or more than a preset appropriate temperature range, the number of revolutions per minute of the compressor cooling fan 1720 is increased by a predetermined constant deceleration rpm to increase the compressor. When the temperature is lowered and the internal temperature (hereinafter referred to as the compressor temperature) of the compressor 1120 is less than a preset suitable temperature range, the revolutions per minute of the compressor cooling fan 1720 is set to a predetermined constant acceleration rpm. It can be implemented as a control method to increase the lower the compressor temperature.

First, after the operation step of the compressor (step S100), a first temperature measurement step (step S200) of measuring the first temperature until a preset first time elapses may be performed. Here, the preset first time is a time previously input to the controller 1600 and periodically after the elapsed time after the compressor 1120 starts operating or after the elapsed time after the compressor 1120 starts operating, the first temperature is periodically adjusted. It means the first waiting time to wait to recalculate the average. For example, when the first time is set to 30 seconds, the temperature is measured for 30 seconds after the operation of the compressor is started to obtain an average of the first temperature. If the first temperature average is less than the first reference temperature, the first temperature average is obtained again for 30 seconds of waiting time. The first temperature average is repeatedly calculated for a waiting time until the average of the first temperatures exceeds the first reference temperature. Thereafter, a step of comparing the average of the first temperature with a preset first reference temperature (step S300) is performed.

When the average of the first temperatures is greater than or equal to the first reference temperature, a first operation step (step S400) of operating the compressor cooling fan 1720 at a preset first rpm may be included. After the first operation step, a second temperature measurement step (step S500) of measuring a second temperature until a preset second time elapses may be further included. Here, the preset second time is a time previously input to the control unit 1600 to wait to recalculate the average of the second temperature periodically after the first operation step or after the first operation step. Means the second waiting time. After that, the step of comparing the average of the second temperature with the preset first reference temperature (step S501) or the step of comparing with the preset second reference temperature (step S503).

If the second temperature average of the compressor 1120 during the second time is less than a preset first reference temperature, the step of decelerating the revolutions per minute of the compressor cooling fan 1720 by a predetermined deceleration revolutions per minute (rpm) (S502) Step) and an acceleration step (S504) of increasing the revolutions per minute of the compressor cooling fan 1720 by a preset acceleration revolutions per minute (rpm) when the average of the second temperatures of the compressor 1120 is higher than a preset second reference temperature. Step) may be further included. That is, the proper operating temperature of the compressor 1120 should be within a range that is above the first reference temperature and less than the second reference temperature while operating at a preset first rpm, and if the temperature range is not satisfied, the compressor is cooled. This is a method of varying the number of revolutions per minute of the fan 1720 to maintain an appropriate operating temperature. This method includes the purpose of reducing noise of the compressor cooling fan 1720 while maintaining the performance of the compressor 1120 as much as possible.

When the decelerating step and the accelerating step have been performed and the proper operating temperature of the compressor 1120 is maintained, the compressor 1120 is passed through a step of checking whether the compressor 1120 operates (step S600). In case of operation, the second temperature measurement step (S500 step) may be repeated again. When the compressor 1120 does not operate, a step of ending the operation of the compressor cooling fan 1720 (step S700) is performed. That is, the operation of the compressor 1120 is varied from the start to the end of the compressor cooling fan 1720 so that the operation of the compressor 1120 is maintained within an appropriate operating temperature.
