Description

The present invention relates to a washer/dryer.

Conventionally, a pulsator placed at the bottom of the washing/dehydrating tub creates a water flow in the washing/dehydrating tub to wash clothes, which is a so-called spiral washing machine (fully automatic washing machine) equipped with a clothes drying function. Dryers are known. An example of such a washer/dryer is described in Patent Document 1, for example.

In the washer/dryer of Patent Document 1, a circulation duct that circulates warm air between itself and an outer tub (water tub) is provided, and a blower and a heater are arranged in the circulation duct. An outside air introduction duct that takes in outside air through an opening is provided upstream of the blower in the circulation duct. The opening is opened and closed by the opening/closing member. Further, an exhaust duct is provided in order to discharge hot air from the outer tank to the outside of the machine.

An internal air circulation period and an external air introduction period are provided in the drying process. During the inside air circulation period, the opening is closed by the opening/closing member, and the outside air is not introduced into the circulation duct. For this reason, almost no air is exhausted from the inside of the outer tub through the exhaust duct, and the temperature in the washing/dehydrating tub (dehydrating tub) rises quickly due to the circulation of warm air between the drying duct and the outer tub. When the temperature inside the washing/dehydrating tank rises and the moisture evaporates from the laundry and the warm air contains a large amount of moisture, the outside air introduction period is switched to. The opening is opened by the opening/closing member, and the outside air is introduced into the circulation duct. The outside air is heated by the heater to become warm air and is supplied into the outer tank together with the circulating warm air. As a result, a part of the warm air containing a large amount of water in the outer tub is discharged to the outside of the machine through the exhaust duct, so that the water evaporated from the laundry is effectively removed from the inside of the outer tub to the outside of the machine. Is discharged.

JP, 2012-075546, A

In the above-mentioned washing/drying machine, foreign matter such as lint discharged from the laundry in the washing/dehydrating tub can be taken into the circulation duct together with warm air. Further, foreign matter such as dust may be taken into the circulation duct together with the outside air. Therefore, it is necessary to collect these foreign substances with a filter so that these foreign substances do not adhere to the heater.

However, when a filter for collecting foreign matter contained in the outside air and a filter for collecting foreign matter contained in warm air are separately provided, a space for arranging each filter is required in the housing, and the housing is required. There is concern that the size of the body will increase.

Therefore, the present invention satisfactorily collects foreign matter contained in warm air introduced into the circulation air passage from the outer tub and foreign matter contained in the outside air taken into the circulation air passage while suppressing an increase in the size of the housing. An object is to provide a washing and drying machine that can be used.

A washer/dryer according to a main aspect of the present invention has an outer tub elastically supported in a housing, a washing/dehydrating tub rotatably arranged in the outer tub, a heater, and a fan. A circulation air passage in which warm air generated by the operation of the heater and the blower fan circulates with the outer tub, an outside air intake for taking in outside air into the circulation air passage, and a temperature from the outer tub An exhaust port for discharging air to the outside of the outer tub and the circulation air passage; and an intake filter chamber provided in the circulation air passage on the upstream side of the flow of warm air with respect to the heater and the blower fan. An intake filter housed in the intake filter chamber. Here, the intake filter is obliquely arranged in the intake filter chamber so that one end side is higher and the other end side is lower. Then, in the intake filter chamber, an outside air introduction port into which the outside air taken in from the outside air intake port is introduced into one of two spaces in the intake filter divided by the intake filter and the outside air. An inside air inlet for introducing warm air from the tank is formed, and an outlet for discharging the warm air and the outside air passing through the intake filter is formed on the other space side.

According to the above configuration, the foreign matter contained in the outside air and the foreign matter contained in the circulating warm air can be collected by one intake filter. Therefore, as compared with the case where these foreign substances are collected by separate filters, the space in the housing required for the filters can be reduced, and the size of the housing is less likely to increase. Moreover, since the intake filter is obliquely arranged so that one end side is high and the other end side is low in the intake filter chamber, a large foreign matter collecting area can be secured without raising the intake filter chamber. Therefore, even if a large amount of foreign matter is collected in the intake filter by collecting foreign matter contained in the outside air and warm air with only one intake filter, the intake filter is less likely to be clogged. It is possible to suppress an increase in the frequency of. Further, it is possible to prevent the height of the housing from increasing.

In the washer/dryer according to the present aspect, the intake filter chamber intersects with a first surface on which the outside air inlet is formed and a second surface on which the inside air inlet is formed. And a third surface that faces the first surface or the second surface and in which the lead-out port is formed.

In the case of such a configuration, a configuration may be adopted in which a holding frame that holds the intake filter and that is housed in the intake filter chamber together with the intake filter is further provided. In this case, the holding frame includes a first wall surface along the first surface and a second wall surface along the second surface, and the outside air circulation port through which the outside air passes through the first wall surface. An inside air circulation port is formed on the second wall surface through which warm air passes.

According to the above configuration, since the intake filter is reinforced by the holding frame, when the intake filter is attached to or detached from the filter chamber, the intake filter is unlikely to be deformed or damaged. Further, the outside air and the inside air passage formed in the holding frame allow the outside air and the warm air to flow smoothly to the intake filter.

In the case of the above configuration, the hinge portion provided between the end portion of the intake filter and the end portion of the holding frame in the direction along the first surface and the second surface causes the intake filter to A configuration may be adopted in which the holding frame and the holding frame are separably connected to each other.

With such a configuration, the intake filter can be easily cleaned by rotating the intake filter about 90 degrees without opening the intake filter wide.

As described above, when the outside air inlet is formed on the first surface, the inside air inlet is formed on the second surface, and the outlet is formed on the third surface, the first surface and the A configuration may be adopted in which an insertion port for inserting the intake filter into the intake filter chamber is formed on a fourth surface that intersects the second surface.

According to the above configuration, the intake filter is easily inserted into the intake filter chamber by inserting the intake filter from the insertion port formed on the fourth surface where the outside air introduction port, the inside air introduction port, and the discharge port are not formed. Can be placed.

In the washer/dryer according to this aspect, an exhaust air passage through which warm air discharged from the exhaust port flows, an exhaust filter chamber provided in the exhaust air passage, and an exhaust filter housed in the exhaust filter chamber are provided. The structure further provided can be taken. In this case, the exhaust filter chamber is formed so as to be continuous with the intake filter chamber in the insertion direction of the intake filter, and is connected to the intake filter chamber. The exhaust filter is integrally formed with the intake filter so as to be continuous in the insertion direction of the intake filter. When the intake filter is housed in the intake filter chamber, it is housed in the exhaust filter chamber. A partition is provided between the intake filter and the exhaust filter to partition the intake filter chamber and the exhaust filter chamber.

With such a configuration, the intake filter and the exhaust filter can be treated as one filter, which is highly convenient for the user. Moreover, when the intake filter and the exhaust filter are housed in the intake filter chamber and the exhaust filter chamber, respectively, the partition blocks the communication between the intake filter chamber and the exhaust filter chamber. Air leakage is unlikely to occur between the exhaust filter chamber and the exhaust filter chamber.

When the exhaust filter is provided integrally with the intake filter, the collecting area of the intake filter may be larger than the collecting area of the exhaust filter.

With this configuration, since the amount of air passing through the exhaust filter is smaller than the amount of air passing through the intake filter, even if the amount of foreign matter collected by the exhaust filter becomes smaller than the amount of foreign matter collected by the intake filter, An extreme difference in the degree of accumulation of foreign matter is unlikely to occur between the filter and the exhaust filter. For this reason, it is unlikely that the intake filter is severely clogged, but the exhaust filter is hardly clogged, and it is possible to effectively remove foreign matter from the intake filter and the exhaust filter with a single cleaning. it can.

When the exhaust filter is provided integrally with the intake filter as described above, the exhaust filter may be obliquely arranged in the exhaust filter chamber so as to face the same direction as the intake filter.

With such a configuration, the exhaust filter can have the same shape as the intake filter, and the exhaust filter can be easily formed integrally with the intake filter.

The wording "same direction" in claim 7 includes "almost the same direction".

According to the present invention, while suppressing an increase in the size of the housing, foreign matter contained in the warm air introduced into the circulation air passage from the outer tub and foreign matter contained in the outside air taken into the circulation air passage are well collected. A washer/dryer capable of being provided can be provided.

Since the intake air holding frame 321 holds the inclined intake air filter 311 on its upper surface, the cross-sectional shape when viewed from the front constitutes a substantially right triangle. In the intake air holding frame 321, an outside air circulation port 323 having a plurality of openings is formed on the left side wall surface 321a, and an inside air circulation port 324 having a plurality of openings is formed on the bottom wall surface 321b. The left wall surface 321a and the bottom wall surface 321b correspond to the first wall surface and the second wall surface of the present invention, respectively.

The exhaust holding frame 322 is formed in a box shape whose upper surface is open. Since the exhaust holding frame 322 holds the inclined exhaust filter 312 on its upper surface, the exhaust holding frame 322 has a substantially right-angled triangular cross-section when viewed from the front. The front and rear dimensions of the exhaust holding frame 322 are smaller than the front and rear dimensions of the intake holding frame 321, and the vertical and horizontal dimensions are larger than the vertical and horizontal dimensions of the intake holding frame 321. In the exhaust holding frame 322, an exhaust flow port 325 having a plurality of openings is formed on the left side wall surface 322a. The rear wall surface 322b of the exhaust holding frame 322, which also serves as the front wall surface 321c of the intake air holding frame 321, is combined with the partition 313 of the filter body 310 to form a partition plate 350. The partition plate 350 corresponds to the partition section of the present invention.

The front panel 330 is formed integrally with the exhaust holding frame 322 in front of the exhaust holding frame 322 and has a rectangular shape that is long in the left-right direction. On the front panel 330, a handle 331 is formed on the front surface, and a mounting plate 332 for mounting the insertion port packing 333 is formed on the rear surface. The insertion port packing 333 is formed in a rectangular ring shape that is long in the left-right direction, and is attached to the outer peripheral edge of the attachment plate 332. The insertion port packing 333 is formed with a tongue-shaped piece 333a that expands rearward in a trumpet shape.

The hinge portion 340 is provided between the rear end portion of the intake filter 311 and the rear end portion of the intake holding frame 321, that is, the upper edge portion of the rear wall surface 321d. For example, the shaft portion 341 of the hinge portion 340 is formed on the intake filter 311 side, and the bearing portion 342 of the hinge portion 340 is formed on the intake holding frame 321 side. As shown by the broken line in FIG. 8A, the filter body 310 can be rotated rearward with respect to the filter holder 320 by rotating about the hinge 340 as a fulcrum.

The insertion port 221 of the filter chamber 220 faces the inside of the outer insertion port 14 of the top plate 12, and the filter unit 53 is inserted into and removed from the filter chamber 220 through the insertion port 221 in the outside insertion port 14. When the filter unit 53 is inserted into the filter chamber 220, the intake filter 311 and the intake holding frame 321 are inserted into the intake filter chamber 250 through the insertion port 270a. The bottom wall surface 321b of the intake air holding frame 321 is gently inclined upward from the inside air circulation port 324, so that the filter unit 53 has a shape in which the tip portion is vertically tapered (see FIG. 9). ). Therefore, when the user inserts the filter unit 53 into the filter chamber 220, the intake filter 311 and the intake holding frame 321 can easily pass through the insertion opening 270a. Further, since the partition frame 270 does not have the partition packing 272 on the inner peripheral edge side of the insertion port 270a, the intake filter 311 and the intake holding frame 321 do not get caught on the partition packing 272, and the insertion port 270a does not get caught. It is easier to pass through.

As shown in FIG. 9, when the filter body 310 and the filter holder 320 are housed in the filter chamber 220, the partition plate 350 of the filter unit 53 and the partition packing 272 of the partition frame 270 abut in the insertion direction. .. As a result, the space between the intake filter chamber 250 and the exhaust filter chamber 260 is partitioned by the partition plate 350 and the partition frame 270, and the communication between the intake filter chamber 250 and the exhaust filter chamber 260 is cut off. Further, the filter chamber 220, that is, the exhaust filter chamber 260 is closed by the front panel 330. In this state, the insertion port packing 333 comes into contact with the peripheral edge of the insertion port 221 in the insertion direction.

As shown in FIG. 10, the intake filter 311 is provided between the outside air inlet 251, the inside air inlet 252, and the outlet 253 so as to close the space between the left side surface 250a and the right side surface 250c in the intake filter chamber 250. It is placed diagonally. Further, the outside air circulation port 323 and the inside air circulation port 324 of the intake air holding frame 321 face the outside air introduction port 251 and the inside air introduction port 252, respectively.

As shown in FIGS. 11 and 12, the exhaust filter 312 is provided between the exhaust inlet 261 and the exhaust outlet 262 so as to close the left side surface 260a and the right side surface 260c in the exhaust filter chamber 260. It is placed diagonally. Further, the exhaust circulation port 325 of the exhaust holding frame 322 faces the exhaust introduction port 261.

The intake air passage 210 and the intake filter chamber 250 of the air passage unit 52, together with the casing 100 of the warm air generation unit 51, form a circulation air passage 50a through which hot air circulates between the outer tub 20 and the casing.

The intake duct 54 is a flexible duct, is made of an elastic material such as rubber, and has a bellows portion 54a at an intermediate portion. Similarly, the exhaust duct 55 is also a flexible duct, is made of an elastic material such as rubber, and has a bellows portion 55a at an intermediate portion. As shown in FIG. 2, in the outer tank cover 20b, an intake port 22b and an exhaust port 22c are formed behind the inner charging port 22a, the lower end of the intake duct 54 is connected to the intake port 22b, and the exhaust duct 55 is provided. The lower end is connected to the exhaust port 22c.

With reference to FIGS. 3, 11 and 12, water supply device 60 includes a water supply unit 61, a water supply valve 62, a bath water pump 63, and a water supply duct 64. The water supply unit 61 includes a water supply case 410, a detergent container 420 that can be taken in and out of the water supply case 410, and a water supply pipe 430 through which water discharged from the water supply case 410 passes. The water supply unit 61 and the water supply duct 64 form a water supply path 60a through which the water supplied into the outer tub 20 flows.

The water supply case 410 is provided with a water channel 411 in the upper part, and the water channel 411 is connected with the water supply valve 62 and the bath water pump 63. A water supply port 412 is formed on the bottom surface of the water supply case 410, and a water supply pipe 430 is connected to the water supply port 412. The detergent container 420 contains a detergent and a softening agent. The detergent container 420 is put into and taken out of the water supply case 410 in the outer charging port 14.

A branch port 431 is formed on the right inner surface of the water supply pipe 430, and a branch pipe 440 extending obliquely upward is formed integrally with the water supply pipe 430 so as to branch from the branch port 431. The branch pipe 440 is connected to the exhaust introduction port 261 of the exhaust filter chamber 260. The water supply pipe 430 is provided with an eave-shaped projecting portion 432 that projects inward, above the branch port 431, that is, on the upstream side of the flow of water with respect to the branch port 431.

A check valve unit 450 is provided at the water supply port 412 of the water supply case 410, which is on the upstream side of the water flow from the branch port 431 of the water supply pipe 430 and on the downstream side of the water flow from the detergent container 420.

The check valve unit 450 includes a ring portion 452 having a water passage 451 and a foot valve 453 that closes the water passage 451 from below. The foot valve 453 is made of an elastic material such as rubber, and a fixed portion 453a at one end thereof is fixed to the ring portion 452. The foot valve 453 is maintained at a position where it blocks the water passage port 451 due to its elastic force, and when a force due to the water flow is applied, the foot valve 453 opens obliquely with the fixed portion 453a as a fulcrum. The branch port 431 of the water supply pipe 430 is provided on the fixed portion 453a side of the foot valve 453.

The water supply duct 64 is a flexible duct, is made of an elastic material such as rubber, and has a bellows portion 64a at an intermediate portion. The upper end of the water supply duct 64 is connected to the water supply pipe 430. As shown in FIG. 2, the outer tank cover 20b has a water supply port 22d formed behind the inner charging port 22a, and the lower end of the water supply duct 64 is connected to the water supply port 22d.

The branch pipe 440 constitutes an exhaust air passage 50b for exhausting warm air to the outside of the fully automatic washing and drying machine 1 together with the exhaust filter chamber 260 of the air passage unit 52 and the hot air exhaust passage 240.

The drying device 50 is connected to the outer tub 20 by a flexible intake duct 54 and an exhaust duct 55, and the water supply device 60 is connected to the outer tub 20 by a flexible water supply duct 64. Therefore, when the outer tub 20 sways, the sway is absorbed by the intake duct 54, the exhaust duct 55, and the water supply duct 64, and the warm air generating unit 51, the air passage unit 52, the filter unit 53, and the water supply of the drying device 50. The water supply unit 61, the water supply valve 62, and the bath water pump 63 of the device 60 are less likely to be subjected to shaking force.

In the fully automatic washer/dryer 1, a washing operation, a washing/drying operation, or a drying operation of various driving courses is performed. The washing operation is an operation for performing only washing, and the washing process, the intermediate dewatering process, the rinsing process, and the final dewatering process are sequentially executed. The washing/drying operation is an operation in which washing and drying are continuously performed, and the drying step is executed subsequent to the final dehydration step. The drying operation is an operation in which only drying is performed, and only the drying process is executed.

In the washing process and the rinsing process, the pulsator 26 rotates to the right and to the left while water is stored in the washing/dehydrating tank 24. Due to the rotation of the pulsator 26, a water flow is generated in the washing/dehydrating tank 24. In the washing step, the laundry is washed with the generated water flow and the detergent contained in the water. In the rinsing step, the generated water flow rinses the laundry.

In the water supply process in the washing process and the rinsing process, the water supply valve 62 is opened. Alternatively, when bath water is used, the bath water pump 63 operates. As a result, tap water or bath water is supplied to the water channel 411 of the water supply case 410. The water supplied to the water channel 411 is mixed with the detergent and the softening agent through the detergent container 420 and reaches the water supply port 412 of the water supply case 410.

As shown in FIG. 11, within the water supply port 412, the foot valve 453 is opened by being pushed by the water flow, and the water flowing out from the water supply port 451 passes through the water supply pipe 430 and the water supply duct 64 and the water supply port 22d of the outer tub cover 20b. Is supplied from the inside to the outer tub 20. Here, as shown by the arrow in FIG. 11, a part of the water flowing through the water supply pipe 430 flows along the foot valve 453. The water transmitted through the foot valve 453 is directed to the side opposite to the fixed portion 453a side in the water supply pipe 430, and is hard to reach the branch port 431 on the fixed portion 453a side. Therefore, when supplying water, it is difficult for water to enter the branch pipe 440. Further, since water flowing on the fixed portion 453a side also hits the overhanging portion 432 and moves away from the branch port 431, it is more difficult for water to enter the branch pipe 440. Further, even if water should enter the branch pipe 440, the invading water is likely to return to the water supply pipe 430 due to the inclination of the branch pipe 440.

In the intermediate dehydration step and the final dehydration step, the laundry dehydration tub 24 and the pulsator 26 integrally rotate at high speed. The laundry is dehydrated by the action of the centrifugal force generated in the washing/dehydrating tank 24.

In the drying step, the inside air circulation drying step is first performed, and then the outside air introducing drying step is performed. In the inside air circulation drying step, the outside air intake port 231 is closed by the flap 281 (see the flap 281 in the solid line in FIG. 10), and the blower fan 110 and the heater 120 operate in a state where the outside air is not introduced into the outside air introduction passage 230. When the blower fan 110 operates and the blower 111 rotates, as shown in FIG. 4B, air is sucked in from the suction port 103 and wind is generated in the casing 100. The generated wind is heated by the heater 120, becomes warm air, is discharged from the discharge port 104, and is supplied into the outer tub 20 through the intake duct 54.

The warm air supplied into the outer tub 20 flows through the washing/dehydrating tub 24. In the washing/dehydrating tub 24, the pulsator 26 rotates clockwise and counterclockwise at regular intervals. The laundry in the washing/dehydrating tub 24 comes into contact with the warm air flowing in the washing/dehydrating tub 24 while being stirred by the pulsator 26. As shown in FIG. 10, the warm air flowing through the washing/dehydrating tank 24 is discharged from the inside of the outer tank 20 through the exhaust duct 55, passes through the intake filter chamber 250 and the intake air passage 210, and again from the suction port 103 through the casing 100. Is sucked in.

In the inside air circulation drying step, since the outside air is not taken in, the exhaust from the outer tank 20 through the water supply duct 64 is hardly performed, and the circulation air passage 50a including the casing 100, the intake air passage 210, and the intake filter chamber 250 and the outside air. Hot air is circulated between the tank 20 and the tank 20, so that the temperature in the washing/dehydrating tank 24 is rapidly increased.

The warm air discharged from the outer tub 20 is mixed with foreign matter such as lint discharged from the laundry due to stirring by the pulsator 26 or the like. The hot air passes through the intake filter 311 in the intake filter chamber 250, and foreign matter contained in the hot air is collected by the intake filter 311.

When the temperature inside the washing/dehydrating tub 24 rises and the moisture evaporates from the laundry and the warm air contains a large amount of moisture, the process is switched to the outside air introduction drying step. The switching to the outside air introduction drying step may be performed based on the lapse of time after the drying step is started, or the temperature inside the outer tank 20 detected by the temperature sensor and the outer tank detected by the humidity sensor may be changed. It may be performed based on the humidity within 20.

In the outside air introduction drying step, the flap 281 is opened and the outside air intake port 231 is opened (see the flap 281 of the broken line in FIG. 10), and the blower fan 110 and the heater 120 are operated in a state where the outside air is introduced into the outside air introduction passage 230. Operate. As shown in FIG. 10, the outside air introduced into the outside air introduction passage 230 flows into the intake air passage 210 while being mixed with the warm air flowing from the exhaust duct 55 through the intake filter chamber 250, and the outside air is mixed. The hot air thus drawn is sucked into the casing 100. At this time, the outside air passes through the intake filter 311 in the intake filter chamber 250, and foreign matters such as dust contained in the outside air are collected by the intake filter 311.

In the outside air introducing/drying step, since the flow rate of the warm air supplied into the outer tub 20 increases as the outside air is taken in, a part of the warm air containing a large amount of water in the outer tub 20 is partially discharged to the water supply passage 60a and the exhaust gas. The air is discharged to the outside of the housing 10 through the air passage 50b. That is, as shown in FIG. 12, a part of the warm air in the outer tub 20 is discharged to the water supply pipe 430 through the water supply duct 64 and sequentially flows through the branch pipe 440, the exhaust filter chamber 260, and the warm air discharge path 240, It is discharged from the exhaust hole 12a of the upper plate 12. At this time, the warm air that has flowed into the water supply pipe 430 hits the overhanging portion 432 that is inclined upward toward the branch port 431 and is guided to the branch port 431 side, so that the hot air flows from the branch port 431 into the branch pipe 440. It is easy to enter. Further, since the foot valve 453 is in the state where the water passage port 451 is closed, the warm air in the water supply pipe 430 is prevented from flowing into the water supply case 410. Further, the warm air discharged to the warm air discharge path 240 passes through the exhaust filter 312 in the exhaust filter chamber 260, and foreign matter such as lint contained in the warm air is collected by the exhaust filter 312.

By performing the outside air introduction drying step in this manner, the water evaporated from the laundry is effectively discharged from the outer tub 20 to the outside of the housing 10, and the inside of the outer tub 20 is easily dehumidified, so that the laundry is washed. Drying is accelerated. Since a part of the warm air from the outer tub 20 flows through the circulation air passage 50a and is reheated by the heater 120, the temperature inside the outer tub 20 is continuously maintained high. When the outside air introduction drying step is completed, the drying step is completed.

Since the partition plate 350 and the partition frame 270 shield the space between the intake filter chamber 250 and the exhaust filter chamber 260, the warm air flowing through the exhaust air passage 50b is located inside the filter chamber 220 on the side of the circulation air passage 50a. Is prevented from leaking.

While the washing/drying operation and the drying operation are repeatedly performed, foreign substances are accumulated on the filter material 316 of the intake filter 311 and the filter material 319 of the exhaust filter 312. When the clogging of the intake filter 311 and the exhaust filter 312 due to foreign matter becomes large, the filter unit 53 is pulled out from the filter chamber 220 in order to clean the filters 311 and 312. Then, the filter body 310 is opened with respect to the filter holder 320, the intake surface side of the filter material 316 of the intake filter 311 and the filter material 319 of the exhaust filter 312 are cleaned, and the foreign matter adhering to the intake surface side is removed. ..

<Effects of this embodiment>
As described above, according to the present embodiment, since intake filter 311 is provided between outside air introduction port 251, inside air introduction port 252 and outlet port 253, the foreign matter contained in the outside air and the foreign matter contained in the circulating warm air. And can be collected by one intake filter 311. Therefore, as compared with the case where these foreign matters are collected by separate filters, the space in the housing 10 required for the filters can be reduced, and the size of the housing 10 is less likely to increase. Moreover, since the intake filter 311 is obliquely arranged in the intake filter chamber 250 so that one end side, that is, the left end side is high and the other end side, that is, the right end side is low, the intake filter chamber 250 does not need to be raised. It is possible to secure a large area for collecting foreign matters by the filter material 316. Therefore, even if the amount of foreign matter collected by the intake filter 311 is increased by collecting foreign matter contained in the outside air and warm air with only one intake filter 311, the intake filter 311 is less likely to be clogged. It is possible to suppress an increase in the frequency of cleaning the filter 311. Further, it is possible to prevent the height of the housing 10 from increasing.

Further, according to the present embodiment, the filter chamber 220 in which the intake filter chamber 250 and the exhaust filter chamber 260 that communicate with each other are integrally formed is provided, and the intake filter 311 and the exhaust filter 312 are integrally formed. Since the configured filter unit 53 is configured to be attached to and detached from the filter chamber 220, the intake filter 311 and the exhaust filter 312 can be treated as one filter, which is highly convenient for the user. Moreover, in the filter unit 53, the partition plate 350 is formed between the intake filter 311 and the exhaust filter 312, and when the filter unit 53 is inserted into the filter chamber 220, the partition plate 350 causes the intake filter chamber 250 and the exhaust gas to be exhausted. Since the communication with the filter chamber 260 is blocked, air leakage does not easily occur between the intake filter chamber 250 and the exhaust filter chamber 260 during the dry operation.

Furthermore, according to the present embodiment, a partition frame 270 that projects inward is provided in the filter chamber 220, and the partition frame 270 and the partition plate 350 of the filter unit 53 are separated by the intake filter chamber 250 and the exhaust filter chamber 260. Since the contact is made in the lined direction, the intake filter chamber 250 and the exhaust filter chamber 260 can be firmly shielded.

Further, according to the present embodiment, since the partition packing 272 is provided in the partition frame 270 and the partition plate 350 is brought into contact with the partition packing 272, the space between the intake filter chamber 250 and the exhaust filter chamber 260 is arranged. It is possible to shield more firmly.

Furthermore, according to the present embodiment, the partition frame 270 is composed of the frame body 271 and the partition packing 272 which are separate from the filter chamber 220, and the frame body 271 is fitted into the fitting groove 222 on the inner surface of the filter chamber 220. Since the outer peripheral portion 274 of the partition packing 272 is sandwiched between the frame body 271 and the bottom surface of the fitting groove 222, that is, the inner surface of the filter chamber 220 when attached, the partition packing 272 is attached to the filter chamber 220. Can be firmly fixed, and when the partition plate 350 of the filter unit 53 is brought into contact with the partition packing 272, the partition packing 272 is unlikely to shift or come off.

Further, according to the present embodiment, since intake filter chamber 250 and exhaust filter chamber 260 are arranged in the direction in which filter unit 53 is inserted into filter chamber 220, intake filter chamber 250 and exhaust filter chamber 260 are inserted. Unlike the case where the partition packing 272 is provided, unlike the case where the partition packing 272 is provided, the filter unit 53 is inserted into the filter chamber 220 while the partition plate 350 and the partition packing 272 rub against each other. Therefore, it is difficult to insert the filter unit 53 into the filter chamber 220, and the partition packing 272 is not easily damaged.

Furthermore, according to the present embodiment, the insertion port packing 333 is provided between the front panel 330 of the filter unit 53 and the peripheral portion of the insertion port 221 of the filter chamber 220, so that the front panel 330 and the filter chamber 220 are separated from each other. It is possible to firmly seal the space with the insertion port 221.

Further, according to the present embodiment, since the intake filter 311 is held by the intake holding frame 321, and the exhaust filter 312 is held by the exhaust holding frame 322, the strength of the filter unit 53 as a whole is increased, and the filter unit 53 is increased. When the 53 is attached to or detached from the filter chamber 220, the intake filter 311 and the exhaust filter 312 are less likely to be deformed or damaged. Further, even when foreign matter falls from the intake filter 311 and the exhaust filter 312 when the filter unit 53 is removed from the filter chamber 220, the fallen foreign matter is received by the bottom wall surface 321b of the intake holding frame 321 and the bottom wall surface of the exhaust holding frame 322. be able to. Furthermore, the outside air circulation port 323 and the inside air circulation port 324 formed on the intake holding frame 321 allow the outside air and warm air to flow smoothly to the intake filter 311, and the exhaust circulation port 325 formed on the exhaust holding frame 322 controls the temperature. The wind can be smoothly flowed to the exhaust filter 312.

Further, according to the present embodiment, the hinge portion 340 that connects the filter body 310 and the filter holding body 320 to each other so as to be separable is such that the rear end portion of the intake filter 311 and the upper end portion of the rear wall surface 321d of the intake holding frame 321. Since the filter main body 310 is provided between the filter main body 310 and the filter holder 320, the intake filter 311 and the exhaust filter 312 can be easily cleaned by rotating the filter main body 310 about 90 degrees. For example, as shown in FIG. 14A, when the hinge portion is provided between the left end portion of the intake filter and the upper end portion of the left wall surface of the intake holding frame, even if the filter main body is rotated about 90 degrees, Since it is in a slightly downward state, it is necessary to rotate the filter body further largely as indicated by the broken line in order to facilitate cleaning. In addition, as shown in FIG. 14B, when the hinge portion is provided between the right end portion of the intake filter and the upper end portion of the right wall surface of the intake holding frame, the position of the hinge portion is located at the upper end of the left wall surface of the intake holding frame. Since it will be much lower than the part, turning the filter body about 90 degrees and making the filter body slightly upward will obstruct the left side wall surface. Again, in order to facilitate cleaning, as shown by the broken line. It is necessary to rotate the filter body largely.

Furthermore, according to the present embodiment, the intake filter 311 is inserted from the insertion port 270a of the partition frame 270, which is the front surface of the intake filter chamber 250 in which the outside air inlet 251, the inside air inlet 252, and the outlet 253 are not formed. As a result, the intake filter 311 can be easily arranged in the intake filter chamber 250.

Further, according to the present embodiment, the amount of air passing through exhaust filter 312 is smaller than the amount of air passing through intake filter 311, so the amount of foreign matter collected at exhaust filter 312 is equal to the amount of foreign matter collected at intake filter 311. Although it is smaller than the collection amount, the collection area of the intake filter 311 is larger than the collection area of the exhaust filter 312, so that the degree of accumulation of foreign matter between the intake filter 311 and the exhaust filter 312 is extremely large. Difference is unlikely to occur. For this reason, it is unlikely that the intake filter 311 is severely clogged, but the exhaust filter 312 is hardly clogged, and the intake filter 311 and the exhaust filter 312 are effectively cleaned by cleaning the filter unit 53 once. Foreign matter can be removed.

Further, according to the present embodiment, since exhaust filter 312 is arranged obliquely in exhaust filter chamber 260 so as to face the same direction as intake filter 311, exhaust filter 312 has the same shape as intake filter 311. Therefore, the exhaust filter 312 can be easily formed integrally with the intake filter 311. Moreover, since the large collection area of the exhaust filter 312 can be ensured, when the filter units 53 have the same size, the collection area of the intake filter 311 and the collection area of the exhaust filter 312 are set to a predetermined ratio. It is possible to reduce the size of the exhaust filter 312 and increase the size of the intake filter 311 in the direction in which the intake filter 311 and the exhaust filter 312 are arranged while maintaining the same. As a result, the trap area of the intake filter 311 can be further increased while the filter chamber 220 and the filter unit 53 have the determined dimensions.

<Example of change>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and the like, and the embodiments of the present invention can be modified in various ways other than the above. is there.

For example, even if the outside air inlet 251 is formed on the bottom surface 250b of the intake filter chamber 250 instead of the left side surface 250a, and the inside air inlet 252 is formed on the left side surface 250a of the intake filter chamber 250 instead of the bottom surface 250b. Good. Further, a configuration may be adopted in which the outlet 253 is formed on the top surface of the intake filter chamber 250. Further, both the outside air introduction port 251 and the inside air introduction port 252 may be formed on the same surface of the intake filter chamber 250, for example, the left side surface 250a or the bottom surface 250b.

Further, as shown in FIGS. 15A to 15C, the intake filter chamber 250A is not quadrangular when viewed from the front, and has inclined surfaces 250d and 250e substantially parallel to the inclined intake filter 311A on both left and right sides. It may be shaped like this. In this case, for example, as shown in FIGS. 15A and 15B, the outside air introducing port 251A and the inside air introducing port 252A are formed on one inclined surface 250d, and the outlet port 253A is formed on the other inclined surface 250e. Good. Alternatively, as shown in FIG. 15C, one of the outside air introduction port 251A and the inside air introduction port 252A may be formed on one inclined surface 250d and the other may be formed on the bottom surface 250f. That is, the intake filter chamber 250 may have any shape, in short, the outside air introduction port 251 and the inside air introduction to one space side of the two spaces in the intake filter chamber 250 divided by the intake filter 311. The opening 252 and the outlet 253 may be formed on the other space side.

Further, the partition frame 270 may not be provided with the partition packing 272, and in this case, the intake filter chamber 250 and the exhaust filter chamber 260 are arranged in the insertion direction of the filter unit 53 into the filter chamber 220. They may be arranged in the vertical direction.

Further, the partition packing 272 may be provided on the partition plate 350 instead of the partition frame 270. In this case, the partition frame 270 is composed of only the frame body 271. At this time, the frame body 271 may be integrally formed with the inner surface of the filter chamber 220.

Furthermore, the insertion port packing 333 may be provided on the filter chamber 220 side instead of the front panel 330 side.

Further, the exhaust filter 312 may face a slightly different direction from the intake filter 311. The point is that the exhaust filter 312 should face almost the same direction as the intake filter 311.

In addition, the embodiment of the present invention can be appropriately modified in various ways within the scope of the technical idea shown in the claims.
