Description

  The present invention relates to a washing / drying machine.

  Conventionally, a washing machine equipped with a clothes drying function in a so-called spiral washing machine (fully automatic washing machine) that uses a pulsator placed at the bottom of a laundry dewatering tank to generate a water flow in the laundry dewatering tank and wash clothes. Dryers are known. An example of such a washing / drying machine is described in Patent Document 1, for example.

  In the washing / drying machine of Patent Document 1, a circulation duct for circulating hot air between the outer tub (water tank) is provided, and a blower and a heater are arranged in the circulation duct. An outside air introduction duct through which outside air is taken in through the opening is provided upstream of the blower of the circulation duct. The opening is opened and closed by an opening / closing member. Further, an exhaust duct is provided to discharge the hot air from the outer tank to the outside of the apparatus.

  In the drying process, an inside air circulation period and an outside air introduction period are provided. In 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, exhaust through the exhaust duct from the outer tub is hardly performed, and the temperature in the washing dewatering tub (dehydration tub) rises quickly due to the circulation of warm air between the drying duct and the outer tub. When the temperature rises in the laundry dewatering tub and the water evaporates from the laundry and the hot air contains a lot of water, the outside air introduction period is switched. The opening is opened by the opening / closing member, and 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 tub together with the circulating warm air. As a result, a part of the hot air containing a lot of moisture in the outer tub is discharged to the outside of the machine through the exhaust duct, so that the moisture evaporated from the laundry is effectively transferred from the outer tub to the outside of the machine. Discharged.

  In the above-described washing and drying machine, foreign matters such as lint out of the laundry in the laundry dewatering tub can be taken into the circulation duct together with warm air. Moreover, foreign substances such as dust can be taken into the circulation duct along 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 that collects foreign matter contained in the outside air and a filter that collects foreign matter contained in the hot air are provided separately, a space for arranging each filter in the housing is required. There is a concern that the size of the body will increase.

  Therefore, the present invention can satisfactorily collect the foreign matter contained in the warm air introduced from the outer tank into the circulation air passage and the 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 of the present invention is to provide a washing and drying machine that can be used.

  In the washing and drying machine according to the main aspect of the present invention, an outer tub elastically supported in a housing, a laundry dewatering tub disposed rotatably in the outer tub, a heater, and a blower fan are disposed. A circulation air passage through which the warm air generated by the operation of the heater and the blower fan circulates between the outer tub, an outside air intake port for taking outside air into the circulation air passage, and a temperature from the outer tub An exhaust port for discharging the wind out of the outer tub and the circulation air passage; and an intake filter chamber provided on the upstream side of the flow of warm air from the heater and the blower fan in the circulation air passage; And an intake filter housed in the intake filter chamber. Here, the intake filter is disposed obliquely in the intake filter chamber so that one end side is high and the other end side is low. The intake filter chamber has an outside air introduction port through which outside air taken in from the outside air intake port is introduced into one of the two spaces in the intake filter divided by the intake filter. An inside air introduction port through which hot air from the tank is introduced is formed, and an outlet port through which the warm air and the outside air that have passed through the intake filter are led out is formed on the other space side.

  According to said structure, the foreign material contained in external air and the foreign material contained in the warm air which circulates can be collected with one intake filter. Therefore, compared with the case where these foreign substances are collected by separate filters, the space in the casing required for the filter can be reduced, and the size of the casing is not easily increased. In addition, since the intake filter is disposed obliquely in the intake filter chamber so that one end side is high and the other end side is low, a large collection area of foreign matter can be secured without increasing the intake filter chamber. Therefore, by collecting the foreign matter contained in the outside air and warm air with one intake filter, the intake filter is less likely to be clogged even if the amount of foreign matter collected by the intake filter increases. It is possible to suppress an increase in frequency. Moreover, it can suppress that the height of a housing | casing becomes large.

  In the washer / dryer according to this aspect, the intake filter chamber has a first surface on which the outside air introduction port is formed and a second surface on which the first surface is intersected and the inside air introduction port is formed. And a third surface facing the first surface or the second surface and having the outlet opening formed thereon.

  When it is set as such a structure, the structure further provided with the holding frame which hold | maintains the said intake filter and is accommodated in the said intake filter chamber with an intake filter may be taken. 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 an outside air circulation port through which the outside air passes through the first wall surface. An inside air circulation port through which warm air passes is formed in the second wall surface.

  According to the above configuration, since the intake filter is reinforced by the holding frame, the intake filter is not easily deformed or damaged when the intake filter is attached to or detached from the filter chamber. Moreover, the outside air and the warm air can be smoothly flowed to the intake filter by the outside air circulation port and the inside air circulation port formed in the holding frame.

  In the case of the above configuration, the intake filter and the intake filter are provided by a hinge portion provided between an end portion of the intake filter and an end portion of the holding frame in a direction along the first surface and the second surface. A configuration in which the holding frame is connected so as to be separable may be employed.

  With such a configuration, the intake filter can be easily cleaned by simply rotating it by about 90 degrees without opening the intake filter with respect to the holding frame.

  As described above, when the outside air introduction port is formed on the first surface, the inside air introduction port is formed on the second surface, and the outlet port is formed on the third surface, the first surface and 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 intersecting 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 in the fourth surface where the outside air introduction port, the inside air introduction port and the outlet port are not formed. Can be placed.

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

  With such a configuration, the intake filter and the exhaust filter can be handled as one filter, which is highly convenient for the user. In addition, when the intake filter and the exhaust filter are accommodated in the intake filter chamber and the exhaust filter chamber, respectively, the communication between the intake filter chamber and the exhaust filter chamber is blocked by the partition portion. Wind leakage between the exhaust filter chamber and the exhaust filter chamber is difficult.

  When the exhaust filter is provided integrally with the intake filter, a configuration in which the collection area of the intake filter is made larger than the collection area of the exhaust filter may be employed.

  In this way, 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 is smaller than the amount of foreign matter collected by the intake filter, the intake air It is difficult for an extreme difference in the degree of foreign matter accumulation between the filter and the exhaust filter. For this reason, it is unlikely that the exhaust filter is clogged even though the intake filter is severely clogged, and it is possible to effectively remove foreign matter from the intake filter and the exhaust filter with a single cleaning. it can.

  As described above, when the exhaust filter is provided integrally with the intake filter, the exhaust filter may be disposed obliquely 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 term “same direction” in claim 7 includes “substantially the same direction”.

  According to the present invention, the foreign matter contained in the warm air introduced from the outer tub to the circulation air passage and the foreign matter contained in the outside air taken into the circulation air passage are satisfactorily collected while suppressing an increase in the size of the housing. A washing and drying machine that can be provided can be provided.

For example, the shaft part 341 of the hinge part 340 is formed on the intake filter 311 side, and the bearing part 342 of the hinge part 340 is formed on the intake holding frame 321 side. As shown by a broken line in FIG. 8A, the filter main body 310 can be pivoted about the hinge portion 340 and opened rearward with respect to the filter holder 320.

  The insertion port 221 of the filter chamber 220 faces 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 outer 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 holding frame 321 is gently inclined upward on the back side from the inside air circulation port 324, so that the filter unit 53 has a shape in which the tip end is tapered in the vertical direction (see FIG. 9). ). For this reason, when the user inserts the filter unit 53 into the filter chamber 220, the intake filter 311 and the intake holding frame 321 tend to smoothly pass through the insertion port 270a. In addition, since the partition frame 270 does not have the partition packing 272 on the inner peripheral side of the insertion port 270a, the intake filter 311 and the intake holding frame 321 are not caught by the partition packing 272, and the insertion port 270a. Is easier to pass through.

  As shown in FIG. 9, the partition plate 350 of the filter unit 53 and the partition packing 272 of the partition frame 270 come into contact with each other in the insertion direction in a state where the filter main body 310 and the filter holder 320 are accommodated in the filter chamber 220. . Accordingly, the intake 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 intake filter chamber 250 and the exhaust filter chamber 260 is blocked. 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 contacts the peripheral edge of the insertion port 221 in the insertion direction.

  As shown in FIG. 10, the intake filter 311 is located between the outside air inlet 251 and the inside air inlet 252 and the outlet 253 so as to block the space between the left side surface 250 a and the right side surface 250 c in the intake filter chamber 250. Are arranged diagonally. Further, the outside air circulation port 323 and the inside air circulation port 324 of the intake 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 block the space between the left side 260a and the right side 260c in the exhaust filter chamber 260. It is arranged 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 constitute a circulation air passage 50a through which hot air circulates between the outer tub 20 and the casing 100 of the hot air generation unit 51.

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

  Referring 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 constitute a water supply path 60a through which water supplied into the outer tub 20 flows.

  The water supply case 410 includes a water channel 411 at the upper portion, and the water supply valve 62 and the bath water pump 63 are connected to the water channel 411. 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 detergent and softening agent. The detergent container 420 is put in and out of the water supply case 410 in the outer charging port 14.

  A branch port 431 is formed on the inner surface on the right side 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 inlet 261 of the exhaust filter chamber 260. The water supply pipe 430 is formed with a bowl-shaped protruding portion 432 that protrudes inwardly above the branch port 431, that is, upstream of the flow of water from the branch port 431.

  A check valve unit 450 is provided in the water supply port 412 of the water supply case 410 that is upstream of the water flow from the branch port 431 of the water supply pipe 430 and downstream 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 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 foot valve 453 is maintained at a position that closes the water passage 451 by its elastic force, and when force due to water flow is applied, the foot valve 453 opens so as to hang obliquely with the fixing 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 formed of an elastic material such as rubber, and has a bellows portion 64a at an intermediate portion. An upper end portion 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 a lower end portion of the water supply duct 64 is connected to the water supply port 22d.

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

  The drying device 50 is connected to the outer tub 20 by flexible intake ducts 54 and exhaust ducts 55, and the water supply device 60 is connected to the outer tub 20 by flexible water supply ducts 64. Therefore, when the outer tub 20 is shaken, the intake duct 54, the exhaust duct 55, and the water supply duct 64 absorb the shake, and the hot air generating unit 51, the air path unit 52, the filter unit 53, and the water supply of the drying device 50 are absorbed. It is difficult for the water supply unit 61, the water supply valve 62, and the bath water pump 63 of the apparatus 60 to be subjected to shaking.

  In the fully automatic washing / drying machine 1, washing operation, washing / drying operation or drying operation of various operation courses is performed. The washing operation is an operation in which only washing is performed, and a washing process, an intermediate dehydration process, a rinsing process, and a final dehydration process are sequentially performed. The washing and drying operation is an operation in which washing to drying is continuously performed, and the drying step is executed following 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 step and the rinsing step, the pulsator 26 rotates rightward and leftward with water stored in the washing / dehydrating tub 24. As the pulsator 26 rotates, a water flow is generated in the laundry dewatering tub 24. In the washing step, the laundry is washed with the generated water flow and the detergent contained in the water. In the rinsing process, the laundry is rinsed by the generated water flow.

  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. Thereby, 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 passes through the detergent container 420 and is mixed with the detergent and the softening agent, and reaches the water supply port 412 of the water supply case 410.

  As shown in FIG. 11, the foot valve 453 is opened by the water flow in the water supply port 412 and the water flowing out from the water flow port 451 passes through the water supply pipe 430 and the water supply duct 64, and the water supply port 22 d of the outer tub cover 20 b. To the outer tub 20. Here, as shown by the arrow in FIG. 11, a part of the water flowing in the water supply pipe 430 flows so as to travel through the foot valve 453. The water transmitted through the foot valve 453 is directed to the opposite side to the fixed portion 453a side in the water supply pipe 430, and hardly reaches the branch port 431 on the fixed portion 453a side. Therefore, it is difficult for water to enter the branch pipe 440 during water supply. In addition, since the water flowing on the fixed portion 453a side hits the overhanging portion 432 and moves away from the branch port 431, water does not easily enter the branch pipe 440. Furthermore, even if water enters the branch pipe 440, the water that has entered easily returns 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 dewatering tub 24 and the pulsator 26 rotate as a unit at a high speed. The laundry is dehydrated by the action of centrifugal force generated in the laundry dewatering tub 24.

  In the drying process, an inside air circulation drying process is first performed, and subsequently, an outside air introduction drying process 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 indicated by the solid line in FIG. 10), and the blower fan 110 and the heater 120 operate in a state where outside air is not introduced into the outside air introduction path 230. When the blower fan 110 operates and the blower 111 rotates, as shown in FIG. 4B, 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, 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 in the washing / dehydrating tub 24 is discharged from the outer tub 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 to the casing 100. It is sucked in.

  In the inside air circulation drying step, outside air is not taken in, and therefore, there is little exhaust from the inside of the outer tub 20 through the water supply duct 64, and the circulation air passage 50 a composed of the casing 100, the intake air passage 210 and the intake filter chamber 250 and the outside. Hot air circulates between the tank 20 and the temperature in the washing / dehydrating tank 24 rises quickly.

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

  When the temperature rise in the laundry dewatering tub 24 progresses and the moisture evaporates from the laundry and the warm air contains a lot of moisture, the process is switched to the outside air introduction drying process. Switching to the outside air introduction drying process may be performed based on the passage of time from the start of the drying process, or the temperature in the outer tank 20 detected by the temperature sensor and the outer tank detected by the humidity sensor. 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 broken flap 281 in FIG. 10), and the blower fan 110 and the heater 120 are operated while the outside air is introduced into the outside air introduction path 230. Operate. As shown in FIG. 10, the outside air introduced into the outside air introduction passage 230 passes through the intake filter chamber 250 and flows into the intake air passage 210 while being mixed with the warm air flowing from the exhaust duct 55, and the outside air is mixed. The warm 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 matter such as dust contained in the outside air is collected by the intake filter 311.

  In the outside air introduction drying process, the flow rate of the warm air supplied into the outer tub 20 is increased by the amount of outside air taken in, so a part of the warm air containing a large amount of water in the outer tub 20 is partly supplied to the water supply channel 60a and the exhaust. The air is discharged out 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 hot air discharge path 240. The gas is discharged from the exhaust hole 12 a of the top plate 12. At this time, the warm air flowing into the water supply pipe 430 strikes the overhanging portion 432 inclined upward toward the branch port 431 and is guided to the branch port 431 side. It becomes easy to enter. Further, since the foot valve 453 is in a state of closing the water inlet 451, 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 matters such as lint contained in the warm air are collected by the exhaust filter 312.

  By performing the outside air introduction drying process in this way, moisture 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. Drying of is promoted. 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 continuously maintained at a high level. When the outside air introduction drying process ends, the drying process ends.

  In addition, since the space between the intake filter chamber 250 and the exhaust filter chamber 260 is shielded by the partition plate 350 and the partition frame 270, the warm air flowing through the exhaust air passage 50b in the filter chamber 220 is on the circulating air passage 50a side. To prevent leakage.

  While the washing and drying operation and the drying operation are repeatedly performed, foreign matters are accumulated in the filter material 316 of the intake filter 311 and the filter material 319 of the exhaust filter 312. When the air filter 311 and the exhaust filter 312 are clogged with foreign matter, the filter unit 53 is pulled out from the filter chamber 220 in order to clean the filters 311 and 312. Then, the filter main body 310 is opened with respect to the filter holder 320, and the intake surface side of the filter material 316 of the intake filter 311 and the filter material 319 of the exhaust filter 312 is cleaned, and foreign matter attached to the intake surface side is removed. .

<Effects of the present embodiment>
As described above, according to the present embodiment, the intake air filter 311 is provided between the outside air introduction port 251 and the inside air introduction port 252 and the outlet port 253, and therefore, the foreign matter contained in the outside air and the foreign matter contained in the circulating hot air. Can be collected by one intake filter 311. Therefore, compared with the case where these foreign substances are collected by separate filters, the space in the housing 10 required for the filter can be reduced, and the size of the housing 10 is not easily increased. Moreover, since the intake filter 311 is arranged obliquely 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 is not increased. A large collection area of foreign matter by the filter material 316 can be secured. Therefore, even if the amount of foreign matter collected by the intake filter 311 increases by collecting the foreign matter contained in the outside air and warm air by one intake filter 311, the intake filter 311 is less likely to be clogged. It can suppress that the frequency of cleaning of the filter 311 increases. Moreover, it can suppress that the height of the housing | casing 10 becomes large.

  Further, according to the present embodiment, the filter chamber 220 in which the intake filter chamber 250 and the exhaust filter chamber 260 communicating with each other are integrally formed is provided, and the intake filter 311 and the exhaust filter 312 are integrally formed. Since the filter unit 53 is attached to and detached from the filter chamber 220, the intake filter 311 and the exhaust filter 312 can be handled as one filter, which is highly convenient for the user. In addition, a partition plate 350 is formed in the filter unit 53 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 exhaust filter 250 and the exhaust filter 3 to be exhausted. Since the communication with the filter chamber 260 is cut off, it is difficult for air leakage between the intake filter chamber 250 and the exhaust filter chamber 260 during the drying operation.

  Furthermore, according to the present embodiment, the 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 connected to the intake filter chamber 250 and the exhaust filter chamber 260. Since the contact is made in the line-up direction, the space between the intake filter chamber 250 and the exhaust filter chamber 260 can be firmly shielded.

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

  Further, according to the present embodiment, the partition frame 270 is configured by the frame main body 271 and the partition packing 272 that are separate from the filter chamber 220, and the frame main body 271 is formed in the fitting groove 222 on the inner surface of the filter chamber 220. When attached, 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. 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 hardly displaced or detached.

  Further, according to the present embodiment, the intake 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, so that the intake filter chamber 250 and the exhaust filter chamber 260 are inserted. Unlike the case in which 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 are rubbed. 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, since the insertion port packing 333 is provided between the front panel 330 of the filter unit 53 and the peripheral edge portion of the insertion port 221 of the filter chamber 220, the front panel 330 and the filter chamber 220 The space between the insertion port 221 can be tightly sealed.

  Furthermore, 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 When the 53 is attached to and detached from the filter chamber 220, the intake filter 311 and the exhaust filter 312 are less likely to be deformed or damaged. Further, when removing the filter unit 53 from the filter chamber 220, even if foreign matter falls from the intake filter 311 or the exhaust filter 312, the fallen foreign matter is received by the bottom wall surface 321 b of the intake holding frame 321 or 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 in the intake holding frame 321 can smoothly flow outside air and warm air to the intake filter 311, and the exhaust circulation port 325 formed in the exhaust holding frame 322 allows the temperature to flow. Wind can flow smoothly to the exhaust filter 312.

  Further, according to the present embodiment, the hinge portion 340 to which the filter main body 310 and the filter holder 320 are detachably connected is 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. Therefore, the intake filter 311 and the exhaust filter 312 can be easily cleaned by simply rotating the filter body 310 with respect to the filter holder 320 by about 90 degrees without opening it. For example, as shown in FIG. 14 (a), 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, the filter main body can be rotated even if the filter main body is rotated about 90 degrees. Since it is in a slightly downward state, it is necessary to further rotate the filter body as shown by the broken line in order to facilitate cleaning. 14B, when the hinge portion is provided between the right end portion of the intake filter and the upper end portion of the right side wall surface of the intake holding frame, the position of the hinge portion is the upper end of the left side wall surface of the intake holding frame. The wall on the left side is easy to get in the way if the filter body is turned slightly upward by turning the filter body about 90 degrees. It is necessary to rotate the filter main body greatly.

  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 where the outside air introduction port 251, the inside air introduction port 252 and the outlet port 253 are not formed. Thus, the intake filter 311 can be easily arranged in the intake filter chamber 250.

  Furthermore, according to the present embodiment, the amount of air passing through the exhaust filter 312 is smaller than the amount of air passing through the intake filter 311, so that the amount of foreign matter collected by the exhaust filter 312 is the amount of foreign matter collected by the intake filter 311. Although the amount is smaller than the trapped amount, the trapping area of the intake filter 311 is larger than the trapping area of the exhaust filter 312, so that the amount of foreign matter accumulated between the intake filter 311 and the exhaust filter 312 is extreme. Difference is unlikely to occur. For this reason, it is hard to occur that the exhaust filter 312 is hardly clogged although the intake filter 311 is severely clogged, and the intake filter 311 and the exhaust filter 312 can be effectively cleaned by cleaning the filter unit 53 once. It is possible to remove foreign matters.

  Furthermore, according to the present embodiment, the exhaust filter 312 is disposed obliquely in the exhaust filter chamber 260 so as to face the same direction as the intake filter 311, so that the exhaust filter 312 has the same shape as the intake filter 311. Therefore, the exhaust filter 312 can be easily formed integrally with the intake filter 311. Moreover, since a large collection area of the exhaust filter 312 can be secured, when the filter unit 53 is 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. While maintaining the intake filter 311 and the exhaust filter 312, the size of the exhaust filter 312 can be reduced to increase the size of the intake filter 311. Thereby, while the filter chamber 220 and the filter unit 53 are set to a predetermined size, the collection area of the intake filter 311 can be further ensured.

<Example of change>
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 can be made to the embodiments of the present invention in addition to the above. is there.

  For example, the outside air inlet 251 may be formed not on the left side 250a of the intake filter chamber 250 but on the bottom surface 250b, and the inside air inlet 252 may be formed on the left side 250a instead of the bottom surface 250b of the intake filter chamber 250. Good. Further, a configuration in which the outlet port 253 is formed on the top surface of the intake filter chamber 250 may be adopted. Furthermore, 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 and the bottom surface 250b.

  Further, as shown in FIGS. 15A to 15C, the intake filter chamber 250A is not rectangular when viewed from the front, and has inclined surfaces 250d and 250e substantially parallel to the inclined intake filter 311A on the left and right sides. You may be made into such a shape. In this case, for example, as shown in FIGS. 15A and 15B, the outside air inlet 251A and the inside air inlet 252A are formed on one inclined surface 250d, and the outlet 253A is formed on the other inclined surface 250e. Also 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 shape of the intake filter chamber 250 may be any shape. In short, the outside air introduction port 251 and the inside air introduction are provided on one of the two spaces in the intake filter chamber 250 divided by the intake filter 311. It is only necessary that the opening 252 is formed and the outlet port 253 is formed on the other space side.

  The partition frame 270 may not be provided with the partition packing 272. In this case, the intake filter chamber 250 and the exhaust filter chamber 260 are inserted in the filter chamber 220 into the filter chamber 220. They may be arranged in a 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 configured only by the frame main body 271, but at this time, the frame main body 271 is preferably formed integrally with the inner surface of the filter chamber 220.

  Furthermore, the insertion port packing 333 may be provided not on the front panel 330 side but on the filter chamber 220 side.

  Further, the exhaust filter 312 may face in a slightly different direction from the intake filter 311. In short, the exhaust filter 312 may be directed in substantially the same direction as the intake filter 311.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
