Description

Washing and drying machine

Technical field

The invention relates to a washer-dryer.

Background technique

In the so-called pulsator type washing machine (automatic washing machine) which washes clothes by generating a water flow in the washing and dewatering tank by the pulsator disposed at the bottom of the washing and dewatering tub, the washing function of the drying function of the laundry is known. Clothes machine. For example, Patent Document 1 describes an example of such a washer-dryer.

In the washer-dryer of Patent Document 1, a circulation duct that circulates warm air with an outer tub (bucket) is provided, and a blower and a heater are disposed in the circulation duct. An external air introduction duct that takes in outside air through the opening is provided upstream of the air blower of the circulation duct. The opening is opened and closed by the opening and closing member. Moreover, in order to discharge warm air from the outer tub to the outside of the body, an exhaust duct is provided.

During the drying process, there is an internal air circulation period and an external air introduction period. During the internal air circulation, the opening is closed by the opening and closing member, and the outside air is not introduced into the circulation duct. Therefore, exhaust air from the outer tub through the exhaust duct is hardly performed, and since the warm air circulates between the drying duct and the outer tub, the temperature in the washing and dewatering tub (dehydration tub) rises rapidly. When the temperature in the washing and dewatering bucket continues to rise and the moisture evaporates from the laundry to cause a large amount of moisture in the warm air, it is switched to the outside air introduction period. The opening is opened by the opening and closing member, and the outside air is introduced into the circulation duct. The outside air is heated by the heater to become a warm air, and is supplied to the outer tub together with the circulating warm air. As a result, a part of the warm air containing a large amount of moisture in the outer tub is discharged to the outside of the body through the exhaust duct, so that the water evaporated from the laundry is efficiently discharged from the outer tub to the outside of the body.

In the above-described washing and drying machine, foreign matter such as lint coming out of the washings in the washing and dewatering tub can be taken into the circulation duct together with the warm air. In addition, foreign matter such as dust can be taken into the circulation duct together with the outside air. Therefore, it is necessary to collect the foreign matter through the filter on the upstream side of the heater so that the foreign matter does not adhere to the heater. Moreover, foreign matter such as cotton linters can be taken into the exhaust duct together with the warm air coming out of the outer tub. Therefore, it is necessary to pass the filtration before the warm air flowing through the exhaust duct is discharged to the outside of the body. To capture the foreign matter contained in the warm air.

In this case, if the air inlet filter that traps the foreign matter in the wind heated by the heater and the exhaust filter that traps the foreign matter in the wind discharged from the outer tub to the outside of the body can be processed into one filter The device is not as convenient as the filter, and is convenient for the user.

Problems to be solved by the invention

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a washer-dryer capable of processing an air inlet filter and an exhaust filter into a filter, which is highly convenient for the user.

Solution to solve the problem

The washing and drying machine of the main aspect of the present invention comprises: an outer tub elastically supported in the casing; a washing and dewatering tub rotatably disposed in the outer tub; and a warm air supply unit including a heater and a blower fan. Supplying warm air generated by operation of the heater and the blower fan into the outer tub; exhausting portion for discharging warm air from the outer tub to the outside of the body; and a filter chamber including An air inlet filter chamber and an exhaust filter chamber, the inlet air filter chamber is configured to pass air to the warm air supply portion, and the exhaust air filter chamber is connected to the air inlet filter chamber and is provided a wind that is discharged to the exhaust portion; and a filter portion that is detachably mounted in the filter chamber, and includes: an air inlet filter, is received in the air inlet filter chamber; and an air exhaust filter, and The air inlet filter is integrally formed and received in the exhaust filter chamber; and a partition is disposed between the air inlet filter and the exhaust filter and the air inlet filter chamber and the exhaust air The filter chambers are separated from each other.

According to the above configuration, the inlet air filter and the exhaust air filter can be processed into one filter, and the user's convenience is high. Further, when the filter portion is installed in the filter chamber, the communication between the inlet air filter chamber and the exhaust filter chamber is blocked by the filter side partition portion, so that the air inlet filter chamber and the row are less likely to occur during the drying operation. Air leakage between the air filter chambers.

In addition, a configuration may be adopted in which an air inlet port for introducing air from the outside of the body and an air for introducing air from the outer tub are formed in the air inlet filter chamber. The inlet, the wind introduced from the outside air introduction port and the internal air introduction port passes through the air inlet filter.

In this way, the foreign matter contained in the wind taken in from the outside of the body and the foreign matter contained in the wind discharged from the outer tub can be collected by one air inlet filter. Thereby, compared with the case where these foreign materials are collected by the filter provided separately, the space in the casing required for a filter can be narrowed, and it is difficult to enlarge the size of a casing.

In the washer-dryer of the present aspect, a filter chamber side partition portion that protrudes inward may be provided in the filter chamber. In this case, the filter-side partition portion is in contact with the filter chamber-side partition portion along the direction in which the air inlet filter chamber and the exhaust filter chamber are arranged.

According to the above configuration, the air inlet filter chamber and the exhaust filter chamber can be reliably shielded.

In the case where the above configuration is employed, a partition gasket may be provided on the filter chamber side partition portion on a surface that is in contact with the filter side partition portion.

When such a structure is employed, the air inlet filter chamber and the exhaust filter chamber can be shielded more reliably.

As described above, in the case where the filter chamber side partition portion is provided with the partitioning gasket, the filter chamber side partition portion may further include a partition member provided separately from the filter chamber. In this case, the partitioning gasket includes: an abutting portion provided on a surface of the partitioning member facing the filter-side partitioning portion, and abutting against the filter-side partitioning portion; and a fixing portion Extending from the abutting portion and covering an outer peripheral surface of the partitioning member, the fixing portion being constituted by the partitioning member and the filter chamber when the partitioning member is mounted on an inner surface of the filter chamber The inner surface is clamped.

When such a configuration is adopted, the partitioning gasket can be firmly fixed to the filter chamber, and when the filter-side partition portion of the filter portion is brought into contact with the partitioning gasket, the partitioning gasket is less likely to be displaced or deviated.

As described above, in the case where the filter chamber side partition portion is provided with the partitioning gasket, the air inlet filter chamber and the exhaust air filter chamber may be employed along the filter portion. The structure in which the filter chambers are inserted in the direction of arrangement.

When this structure is adopted, the filter side is not separated from the filter side when it is inserted into the filter chamber. The portion is rubbed against the separation gasket, and it is unlikely that the filter portion is hard to be inserted into the filter chamber or the separation gasket is broken.

In addition, a configuration may be adopted between the peripheral edge portion of the insertion port of the filter chamber into which the filter portion is inserted and the abutting surface of the filter portion abutting the peripheral portion. An insertion port gasket is provided.

In this way, the gap between the abutting surface of the filter portion and the insertion port of the filter chamber can be reliably sealed.

Effect of the invention

According to the present invention, it is possible to provide a washer-dryer capable of processing the air inlet filter and the exhaust filter into a filter, which is highly convenient for the user.

For example, the shaft portion 341 of the hinge portion 340 is formed on the side of the air inlet filter 311, and the bearing portion 342 of the hinge portion 340 is formed on the side of the air inlet holding frame 321 . As shown by the broken line in FIG. 8(a), the filter main body 310 can be rotated with the hinge portion 340 as a fulcrum and opened rearward with respect to the filter holder 320.

The insertion opening 221 of the filter chamber 220 faces the outer insertion opening 14 of the upper panel 12, and the filter sheet The element 53 is inserted into the filter chamber 220 through the insertion port 221 in the outer insertion port 14. When the filter unit 53 is inserted into the filter chamber 220, the inlet air filter 311 and the intake air holding frame 321 are inserted into the air inlet filter chamber 250 through the insertion port 270a. The bottom wall surface 321b of the intake air holding frame 321 is inclined obliquely upward from the inner side of the inner air flow port 324, whereby the filter unit 53 has a shape in which the distal end portion is tapered in the vertical direction (see FIG. 9). Therefore, when the user inserts the filter unit 53 into the filter chamber 220, the air inlet filter 311 and the air intake holding frame 321 easily pass through the insertion port 270a. Further, in the partition frame 270, the partition seal 272 is not present on the inner peripheral side of the insertion port 270a, so that the air inlet filter 311 and the air inlet holding frame 321 are not caught by the partition seal 272, and it is easier to smoothly Through the insertion port 270a.

As shown in FIG. 9, in a state in which the filter main body 310 and the filter holder 320 are housed in the filter chamber 220, the partitioning plate 350 of the filter unit 53 and the partitioning gasket 272 of the partition frame 270 are in the insertion direction. Abut on. Thereby, the inlet filter chamber 250 and the exhaust filter chamber 260 are partitioned by the partition plate 350 and the partition frame 270, and the communication between the inlet air filter chamber 250 and the exhaust filter chamber 260 is blocked. Moreover, the filter chamber 220, ie, the exhaust filter chamber 260, is closed by the front surface panel 330. In this state, the insertion port gasket 333 abuts against the peripheral edge portion of the insertion opening 221 in the insertion direction.

As shown in FIG. 10, the air inlet filter 311 is disposed obliquely in the air inlet filter chamber 250 so as to block between the left side surface 250a and the right side surface 250c, and is disposed in the external air introduction port 251 and the internal air introduction port 252. Between the outlets 253. Further, the outside air circulation port 323 and the internal air flow port 324 of the intake air holding frame 321 are opposed to the external air introduction port 251 and the internal air introduction port 252, respectively.

As shown in FIG. 11 and FIG. 12, the exhaust filter 312 is disposed in the exhaust filter chamber 260 so as to be obliquely disposed between the left side surface 260a and the right side surface 260c in the exhaust air introduction port 261 and the exhaust air guide. Between exits 262. Further, the exhaust air flow port 325 of the air discharge holding frame 322 is opposed to the air discharge introduction port 261.

It should be noted that the air inlet path 210 and the air inlet filter chamber 250 of the air passage unit 52 together with the casing 100 of the warm air generating unit 51 constitute a circulation air passage 50a through which the heating air circulates between the air and the outer tub 20.

The air inlet duct 54 is a flexible duct formed of an elastic material such as rubber, and the intermediate portion has a snake abdomen 54a. Similarly, the exhaust duct 55 is also a flexible duct formed of an elastic material such as rubber, and the middle portion has a snake abdomen 55a. As shown in Fig. 2, in the outer tub cover 20b, an air inlet 22b and an air outlet 22c are formed behind the inner inlet port 22a, and the lower end portion of the air inlet duct 54 is connected to the air inlet 22b, and the lower end portion of the air duct 55 is connected. At the exhaust port 22c.

Referring to FIGS. 3, 11, and 12, the water supply device 60 includes a water supply unit 61, a water supply valve 62, a bath water pump 63, and a water supply pipe 64. The water supply unit 61 includes a water supply tank 410, a detergent container 420 that can enter and exit the water supply tank 410, and a water supply pipe 430 through which water discharged from the water supply tank 410 passes. It should be noted that the water supply path 60a through which the water supplied to the outer tub 20 flows is constituted by the water supply unit 61 and the water supply pipe 64.

The water supply tank 410 is provided with a water passage 411 at the upper portion, and a water supply valve 62 and a bath water pump 63 are connected to the water passage 411. Further, a water supply port 412 is formed on the bottom surface of the water supply tank 410, and a water supply pipe 430 is connected to the water supply port 412. A detergent and a softener are contained in the detergent container 420. The detergent container 420 enters and exits the water supply tank 410 in the outside inlet port 14.

In the water supply pipe 430, a branch port 431 is formed on the inner surface on the right side, and a branch pipe 440 extending obliquely upward is integrally formed with the water supply pipe 430 so as to branch from the branch port 431. The branch pipe 440 is connected to the exhaust air introduction port 261 of the exhaust filter chamber 260. In the water supply pipe 430, on the upstream side of the branch port 431, that is, on the upstream side of the water flow of the branch port 431, a flange-like projecting portion 432 that protrudes inward is formed.

The water supply port 412 of the water supply tank 410 is provided with a check valve unit 450 whose water supply port 412 is the upstream side of the water flow of the branch port 431 of the water supply pipe 430 and is the downstream side of the water flow of the detergent container 420.

The check valve unit 450 includes a ring portion 452 having a water outlet 451, and a bottom valve 453 that blocks the water outlet 451 from below. The bottom valve 453 is formed of an elastic material such as rubber, and a fixing portion 453a at one end thereof is fixed to the ring portion 452. The bottom valve 453 is maintained at a position where the water discharge port 451 is blocked by the elastic force thereof, and when the force of the water flow increases, the fixed portion 453a is tilted and sag as a fulcrum to open. The branch port 431 of the water supply pipe 430 is provided on the side of the fixing portion 453a of the bottom valve 453.

The water supply pipe 64 is a flexible pipe formed of an elastic material such as rubber, and the intermediate portion has a snake abdomen 64a. The upper end portion of the water supply pipe 64 is connected to the water supply pipe 430. As shown in Fig. 2, in the outer tub cover 20b, a water supply port 22d is formed behind the inner inlet port 22a, and a lower end portion of the water supply conduit 64 is connected to the water supply port 22d.

It should be noted that the branch pipe 440 constitutes an exhaust passage 50b for discharging warm air to the outside of the fully automatic washer-dryer 1 together with the exhaust filter chamber 260 of the air passage unit 52 and the warm air discharge passage 240.

The drying device 50 is connected to the outer tub 20 through a flexible air inlet duct 54 and an air exhaust duct 55, and the water supply device 60 is connected to the outer tub 20 through a flexible water supply conduit 64. Therefore, when the outer tub 20 is shaken, the air inlet duct 54. The exhaust duct 55 and the water supply duct 64 absorb the shaking, and the force generated by the shaking is difficult to apply to the warm air generating unit 51 of the drying apparatus 50, the air duct unit 52 and the filter unit 53, and the water supply unit of the water supply unit 60. 61. Water supply valve 62 and bath water pump 63.

In the fully automatic washer-dryer 1, the washing operation, the washing and drying operation, or the drying operation of various operation modes are performed. The washing operation is an operation in which only washing is performed, and the washing process, the intermediate dehydration process, the rinsing process, and the final dehydration process are sequentially performed. The washing and drying operation is a continuous washing to drying operation, followed by a drying process after the final dewatering process. The drying operation is a drying operation only, and only the drying process is performed.

In the washing process and the rinsing process, the pulsator 26 is rotated to the right and to the left in a state where water is stored in the washing and dewatering tub 24. A flow of water is generated in the washing and dewatering tub 24 by the rotation of the pulsator 26. During the washing process, the laundry is washed by the generated water stream and the detergent contained in the water. During the rinsing process, the laundry is rinsed through the resulting water stream.

The water supply valve 62 is opened during the water supply process of the washing process and the rinsing process. Alternatively, in the case of using bath water, the bath water pump 63 operates. Thereby, tap water or bath water is supplied to the water path 411 of the water supply tank 410. The water supplied to the water path 411 is mixed with the detergent and the softener through the detergent container 420, and reaches the water supply port 412 of the water supply tank 410.

As shown in Fig. 11, in the water supply port 412, the bottom valve 453 is opened by being pushed by the water flow, and the water flowing out from the water discharge port 451 is supplied from the water supply port 22d of the outer tub cover 20b to the outer tub through the water supply pipe 430 and the water supply pipe 64. 20 inside. Here, as shown by the arrow in FIG. 11, a part of the water flowing through the water supply pipe 430 flows through the bottom valve 453. The water flowing through the bottom valve 453 is hard to go to the branch port 431 located on the side of the fixed portion 453a in the water supply pipe 430 on the opposite side to the side of the fixed portion 453a. Therefore, it is difficult for water to penetrate into the branch pipe 440 at the time of water supply. Further, the water flowing through the side of the fixing portion 453a is also rebounded by the protruding portion 432 away from the branch opening 431, so that it is more difficult for water to penetrate into the branch pipe 440. Moreover, even if water penetrates into the branch pipe 440, the water that has penetrated easily returns to the water supply pipe 430 by the inclination of the branch pipe 440.

During the intermediate dewatering process and the final dewatering process, the washing and dewatering tub 24 and the pulsator 26 are integrally rotated at a high speed. The laundry is dehydrated by the action of centrifugal force generated by washing the dewatering tub 24.

In the drying process, the internal air circulation drying process is first performed, followed by the external air introduction drying process. During the internal air circulation drying process, the external air intake port 231 is closed by the wind deflector 281 When the outside air is not introduced into the outside air introduction path 230, the blower fan 110 and the heater 120 operate in a state where the outside air is not introduced into the outside air introduction path 230. When the blower fan 110 is operated to rotate the blower 111, as shown in FIG. 4(b), air is sucked from the suction port 103 and wind is generated in the casing 100. The generated wind is heated by the heater 120, and the warm air is discharged from the discharge port 104, and is supplied into the outer tub 20 through the air inlet duct 54.

The warm air supplied into the outer tub 20 flows through the washing and dewatering tub 24. In the washing and dewatering tub 24, the pulsator 26 performs right rotation and left rotation for a fixed time. The laundry in the washing and dewatering tub 24 is in contact with the warm air flowing through the washing and dewatering tub 24 while being stirred by the pulsator 26. As shown in FIG. 10, the warm air flowing through the washing and dewatering tub 24 is discharged from the outer tub 20 through the exhaust duct 55, and is again sucked into the casing 100 from the suction port 103 through the air inlet filter chamber 250 and the air inlet duct 210. Inside.

During the internal air circulation drying process, since the outside air is not taken in, the exhaust air from the warm air in the outer tub 20 is hardly passed through the water supply pipe 64, and the warm air includes the casing 100, the intake duct 210, and The circulation air passage 50a of the intake air filter chamber 250 circulates with the outer tub 20, whereby the temperature inside the washing and dewatering tub 24 rises rapidly.

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

When the temperature in the washing and dewatering tub 24 continues to rise and the moisture evaporates from the laundry to cause a large amount of moisture in the warm air, the external air is switched to the drying process. The switching to the external air introduction drying process may be performed based on the elapsed time after the start of the drying process, or based on the temperature in the outer tub 20 detected by the temperature sensor, and the inside of the outer tub 20 detected by the humidity sensor. Humidity is carried out.

In the outside air introduction and drying process, the windshield 281 is opened to open the outside air intake port 231 (refer to the broken windshield 281 of FIG. 10), and the outside air is introduced into the outside air introduction path 230. Next, the blower fan 110 and the heater 120 operate. As shown in FIG. 10, the outside air introduced into the outside air introduction path 230 passes through the air inlet filter chamber 250, mixes with the warm air flowing from the exhaust duct 55, and simultaneously flows to the intake duct 210, and is mixed with the outside air. The warm air is drawn into the housing 100. At this time, the outside air passes through the air inlet filter 311 in the air inlet filter chamber 250, and foreign matter such as dust contained in the outside air is collected by the air inlet filter 311.

In the external air introduction and drying process, the ingested outside air increases the flow rate of the warm air supplied into the outer tub 20, so that a part of the warm air containing a large amount of moisture in the outer tub 20 is passed through the water supply path 60a. And the exhaust passage 50b is discharged to the outside of the casing 10. 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 pipe 64, and sequentially flows through the branch pipe 440, the exhaust filter chamber 260, and the warm air discharge path 240 from the upper panel. The exhaust hole 12a of 12 is discharged. At this time, the warm air flowing into the water supply pipe 430 is rebounded by the protruding portion 432 that is inclined upward toward the branch port 431, and is guided to the branch port 431 side, thereby facilitating entry into the branch pipe 440 from the branch port 431. Further, since the bottom valve 453 is in a state of blocking the water outlet 451, the warm air in the water supply pipe 430 is prevented from flowing into the water supply tank 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.

As described above, by performing the external air introduction drying process, the moisture evaporated from the laundry is efficiently discharged from the inside of the outer tub 20 to the outside of the casing 10, and the inside of the outer tub 20 is easily dehumidified, so that the drying of the laundry can be promoted. It should be noted that 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, so that the temperature in the outer tub 20 is maintained at a high state. The drying process ends when the external air is introduced into the drying process.

It should be noted that the air inlet filter chamber 250 and the exhaust filter chamber 260 are separated by the partition plate 350 and the partition frame 270, thereby preventing the warm air flowing through the exhaust passage 50b from leaking into the filter chamber 220 to The circulation air passage 50a side.

The foreign matter is accumulated in the filter material 316 of the air inlet filter 311 and the filter material 319 of the air discharge filter 312 while the washing and drying operation and the drying operation are repeated. When the air inlet filter 311 and the exhaust air filter 312 become blocked by foreign matter, the filter unit 53 is taken out from the filter chamber 220 in order to remove the

filters

311 and 312. Then, the filter body 310 is opened with respect to the filter holder 320, and the filter material 316 of the inlet air filter 311 and the air inlet side of the filter material 319 of the exhaust filter 312 are cleaned to remove foreign matter adhering to the air inlet side. .

(Effect of the present embodiment)

As described above, according to the present embodiment, the air inlet filter 311 is provided between the external air introduction port 251 and the internal air introduction port 252 and the outlet port 253, so that it can be trapped in the outside air by the air inlet filter 311. Foreign objects and foreign matter contained in the circulating warm air. Thereby, the space in the casing 10 required for the filter can be reduced as compared with the case where the foreign matter is collected by the filters provided one by one, The size of the casing 10 is difficult to increase. Further, since the air inlet filter 311 is disposed in the air inlet 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, it is not necessary to raise the air inlet filter chamber 250, and the increase can be ensured. The trapping area of the foreign material by the filter material 316. Therefore, even if the foreign air contained in the outside air and the warm air is collected by one air inlet filter 311, the amount of foreign matter collected by the air inlet filter 311 is increased, and the air inlet filter 311 is hard to be clogged. It is possible to suppress an increase in the cleaning frequency of the intake air filter 311. Further, it is possible to suppress the height of the casing 10 from becoming large.

Further, according to the present embodiment, a filter chamber 220 in which the inlet air filter chamber 250 and the exhaust air filter chamber 260 which are mutually connected are integrally formed is provided, and the air inlet filter 311 is integrally formed. The filter unit 53 of the exhaust filter 312 is detached from the filter chamber 220. Therefore, the inlet air filter 311 and the exhaust air filter 312 can be processed into one filter, and the user's convenience is high. Also, in the filter unit 53, a partitioning plate 350 is formed between the inlet air filter 311 and the exhaust air filter 312, and when the filter unit 53 is inserted into the filter chamber 220, the air inlet filter chamber 250 is The communication of the exhaust filter chamber 260 is blocked by the partition plate 350, and therefore, air leakage between the intake air filter chamber 250 and the exhaust filter chamber 260 is less likely to occur during the drying operation.

Moreover, according to the present embodiment, a partition frame 270 that protrudes inward is provided in the filter chamber 220, and the partition frame 270 and the partition plate 350 of the filter unit 53 are along the inlet air filter chamber 250 and the row. Since the arrangement direction of the air filter chambers 260 abuts, the air inlet filter chamber 250 and the exhaust filter chamber 260 can be reliably shielded.

Further, according to the present embodiment, the partitioning gasket 272 is provided in the partition frame 270, and the partitioning plate 350 is brought into contact with the partitioning gasket 272, so that the air inlet filter chamber 250 and the exhaust air filtering can be shielded more reliably. Between chambers 260.

Further, according to the present embodiment, the frame body 271 and the partitioning gasket 272 which are provided separately from the filter chamber 220 constitute the partition frame 270, and the frame body 271 is attached to the inner surface of the filter chamber 220. At this time, the outer peripheral portion 274 of the partitioning gasket 272 is sandwiched between the frame body 271 and the inner surface of the filter chamber 220 which is the bottom surface of the fitting groove 222. Therefore, the partitioning gasket 272 can be firmly fixed to the filter chamber. 220, when the partition plate 350 of the filter unit 53 is brought into contact with the partitioning gasket 272, the partitioning gasket 272 is less likely to be displaced or deviated.

Moreover, according to the present embodiment, the inlet air filter chamber 250 and the exhaust filter chamber 260 are arranged in the direction in which the filter unit 53 is inserted into the filter chamber 220, and therefore, with the air inlet filter chamber 250 and the exhaust air Unlike the case where the filter chambers 260 are arranged in a direction perpendicular to the insertion direction, in the case where the partitioning gasket 272 is provided, the filter unit 53 does not cause the partition plate 350 to be inserted into the filter chamber 220. The partitioning seal 272 rubs against each other, and it is difficult to cause the filter unit 53 to be inserted into the filter chamber 220 or the partition seal 272 to be broken.

Moreover, according to the present embodiment, the insertion port gasket 333 is provided between the front surface panel 330 of the filter unit 53 and the peripheral edge portion of the insertion opening 221 of the filter chamber 220, and therefore, the front surface panel 330 can be The insertion port 221 of the filter chamber 220 is reliably sealed.

Moreover, according to the present embodiment, the air intake filter 311 is held by the air intake holding frame 321 and the air discharge filter 312 is held by the air discharge holding frame 322, and therefore, the overall strength of the filter unit 53 is improved. When the filter unit 53 is detached from the filter chamber 220, the inlet filter 311 and the exhaust filter 312 are less likely to be deformed or damaged. Further, when the filter unit 53 is detached from the filter chamber 220, even if the foreign matter falls from the air inlet filter 311 and the exhaust air filter 312, it can be maintained by the bottom wall surface 321b of the air inlet holding frame 321 and the exhaust air. The bottom wall of the frame 322 receives the dropped foreign matter. Further, the outside air and the warm air are smoothly flowed to the air inlet filter 311 through the external air flow port 323 and the internal air flow port 324 formed in the air inlet holding frame 321, and the exhaust air formed in the air discharge holding frame 322 is exhausted. The flow port 325 allows the warm air to smoothly flow to the exhaust filter 312.

Further, according to the present embodiment, the hinge portion 340 to which the filter body 310 and the filter holder 320 are detachably coupled is provided at the rear end portion of the air inlet filter 311 and the upper end portion of the rear wall surface 321d of the air inlet holding frame 321 Therefore, even if the filter main body 310 is not opened relatively large with respect to the filter holder 320, the air inlet filter 311 and the exhaust filter 312 can be easily cleaned by merely rotating it by about 90 degrees. For example, as shown in (a) of FIG. 14, in the case where the hinge portion is provided between the left end portion of the air inlet filter and the upper end portion of the left side wall surface of the air intake holding frame, even if the filter body is rotated by 90 degrees Left and right, the filter body is also in a slightly downward state, and therefore, in order to facilitate the removal, as shown by the broken line, it is necessary to further rotate the filter body. Further, as shown in FIG. 14(b), in the case where the hinge portion is provided between the right end portion of the air inlet filter and the upper end portion of the right side wall surface of the air intake holding frame, the left side of the air intake holding frame Since the position of the hinge portion is relatively lower than the upper end portion of the wall surface, the left side wall surface is liable to become an obstacle as long as the filter body is rotated by about 90 degrees so that the filter body is slightly upward, for easy removal. As shown by the dotted line, it is still necessary to rotate the filter body a large amount.

Moreover, according to the present embodiment, the external air introduction port 251 and the internal air introduction port are never formed. The front surface of the air inlet filter chamber 250 of the outlet 253, that is, the insertion port 270a of the partition frame 270 is inserted into the air inlet filter 311, whereby the air inlet filter 311 can be easily disposed in the air inlet filter chamber 250.

Further, according to the present embodiment, the amount of wind passing through the exhaust filter 312 is smaller than the amount of air passing through the inlet filter 311, and therefore, the amount of trapping of the foreign matter by the exhaust filter 312 is smaller than the amount of trapping the foreign matter by the inlet filter 311. However, the collection area of the inlet filter 311 is larger than the collection area of the exhaust filter 312. Therefore, the accumulation of foreign matter between the inlet filter 311 and the exhaust filter 312 is not easily different. Therefore, it is difficult to cause the air inlet filter 311 to be severely clogged and the exhaust air filter 312 to be almost unblocked. By cleaning the filter unit 53 once, the air inlet filter 311 and the exhaust filter 312 can be effectively operated. Foreign matter removal.

Moreover, according to the present embodiment, the exhaust filter 312 is disposed obliquely in the exhaust filter chamber 260 in the same direction as the inlet air filter 311, and therefore, the exhaust filter 312 can be set to the intake air. The filter 311 has the same shape, and the exhaust filter 312 and the inlet air filter 311 are easily formed integrally. Further, it is possible to ensure an increase in the collection area of the exhaust filter 312, and therefore, in the case where the filter unit 53 is set to the same size, the trapping area of the inlet filter 311 and the exhaust filter 312 can be The ratio of the trapping area remains specified, and the size of the exhaust filter 312 can be reduced and the size of the inlet filter 311 can be increased in the direction in which the inlet filter 311 and the exhaust filter 312 are arranged. Thereby, when the filter chamber 220 and the filter unit 53 are set to a predetermined size, it is possible to ensure that the collection area of the inlet filter 311 is further increased.

(change example)

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications other than the above may be made in the embodiments of the present invention.

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

Further, as shown in (a) to (c) of Fig. 15, the inlet air filter chamber 250A may have a shape which is not quadrangular as viewed from the front, and has a substantially vertical inlet filter 31lA on the left and right sides. Parallel

inclined faces

250d, 250e. In this case, for example, as shown in FIGS. 15( a ) and 15 ( b ), the outside air introduction port 25 lA and the internal air introduction port 252A may be formed on one inclined surface 250 d, and the other inclined surface 250 e may be formed on the other inclined surface 250 d. A lead-out port 253A is formed. Alternatively, as shown in FIG. 15(c), one of the external air introduction port 25lA and the internal 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 shape of the inlet air filter chamber 250 may be any shape. In short, an external air introduction port is formed as long as one of the two spaces in the air inlet filter chamber 250 partitioned by the air inlet filter 311 is formed. 251 and the internal air introduction port 252 may be formed with the outlet 253 on the other space side.

Further, a configuration in which the partitioning gasket 272 is not provided in the partition frame 270 may be employed, in which case the inlet air filter chamber 250 and the exhaust air filter chamber 260 may be inserted into the filter chamber 220 along the filter unit 53. The directions are arranged in a vertical direction.

Moreover, the partitioning gasket 272 may be disposed on the partitioning plate 350 instead of the partitioning frame 270. In this case, the partition frame 270 is constituted only by the frame main body 271, but at this time, the frame main body 271 may be integrally formed with the inner surface of the filter chamber 220.

Moreover, the insertion port gasket 333 may be disposed on the side of the filter chamber 220 instead of the side of the front surface panel 330.

Moreover, the exhaust filter 312 can be oriented in a slightly different direction than the inlet filter 311. In short, it is sufficient that the exhaust filter 312 is oriented in substantially the same direction as the inlet filter 311.

Further, the drying device 50 may have a configuration in which the exhaust duct 55 and the internal air introduction port 252 are not provided, and no warm air is circulated with the outer tub 20. In this case, by the operation of the blower fan 110, the outside air taken in from the outside air intake port 231 is heated by the heater 120 to become warm air and supplied into the outer tub 20 through the air inlet duct 54. Further, the warm air that has come into contact with the laundry is discharged to the exhaust passage 50b through the water supply conduit 64 and the water supply pipe 430, and is discharged outside the casing 10 through the exhaust passage 50b.

In addition, the embodiments of the present invention can be variously modified as appropriate within the scope of the technical spirit of the claims.
