Description

  The present invention relates to an air conditioning unit that is mounted on a device such as a drum-type washing and drying machine and air-conditions circulating air.

  Such an air conditioning unit is already known to be mounted on a drum-type washing / drying machine (see, for example, Patent Document 1). Referring to the drum type washing and drying machine 1 according to the embodiment of the present invention schematically shown in FIG. 14, the air conditioning unit 39 includes a dead space in the back of the water tank 3 in the drum type washing and drying machine 1. Etc., and is connected in the middle of the circulation air passage 5 having the air blowing fan 15. Thereby, the circulation air flow path 5 sucks and exhausts the air in the water tank 3 by driving the blower fan 15, introduces the air into the air conditioning unit 39 from the suction introduction port 391, dehumidifies by the evaporator 31, and by the condenser 32. After heating to dry high-temperature air, it is discharged from the suction outlet 392, blown toward the water tank 3 and returned to the water tank 3, and the laundry in the rotating drum 2 is repeatedly dried to facilitate the washing process. A drying step after the rinsing step is performed.

  For this purpose, an air passage 393 from the suction inlet 391 to the suction outlet 392 is formed between the front and rear opposing walls of the air conditioning case 38 in the air conditioning case 38 having the air suction inlet 391 and the suction outlet 392. Then, the evaporator 31 and the condenser 32 for dehumidifying and heating the air in the middle of the ventilation path 393 are sucked and discharged from the suction introduction side facing one rear wall of the front and rear opposing walls and the other front wall. The suction inlet 391 is provided upward toward the rear wall of the ceiling wall of the air conditioning case 38 and communicates with the suction inlet side from above, and the suction outlet 392 is provided in the air conditioning case 38. It is provided in the lower part of the end wall of this, and it leads to the said suction discharge side from a side.

  On the other hand, in the heat exchanging area, there is provided a storage unit 63 for storing condensed water generated due to the dehumidifying function of the evaporator or water that may enter for some reason, and the water stored in the storage unit 63 is drained by a drain pump 64. However, if foreign matter such as lint accompanying the circulating air flows in, the drainage pump 64 may be clogged or malfunctioned. Therefore, as shown in FIG. A filter 62 is provided.

JP 2008-79861 A

  However, if the lint is received by the filter, it accumulates there and hinders drainage performance. Therefore, it is necessary to periodically remove and clean it, which is inconvenient in use of the washing / drying machine.

  An object of the present invention is to provide a filter and an air conditioning unit that eliminates the need for maintenance by draining water generated or collected in a heat exchange zone through a drainage channel designed to prevent foreign matter such as lint from flowing forward. There is.

In order to achieve the above object, an air conditioning unit according to the present invention has an air conditioning case having an air suction inlet and a suction outlet, and has air in a heat exchange area of a ventilation path from the suction inlet to the suction outlet. In the air conditioning unit in which the dehumidifying heat exchanger that dehumidifies and heats and the heating heat exchanger are divided into the suction introduction side heat exchange area and the suction discharge side heat exchange area, the heat exchange area is provided at the bottom of the heat exchange area water acids, so as to discharge from the projections and drain outlet via a drain passage provided with a throttle portion of the baffle portion for receiving so as not to flow the foreign matter such as lint to previously occurring position in the vicinity of the front Symbol throttle portion One feature is that the protrusions are provided on the upstream side and the downstream side of the throttle portion .

  In such a configuration, the dehumidifying heat exchanger disposed in the heat exchange area formed between the suction air inlet and the suction outlet of the air conditioning case and the heating heat exchanger dehumidify and heat and dry the high temperature. It can be sent out continuously as air. In particular, in the heat exchange area of the ventilation channel, water that has been separated from the moisture in the air that exchanges heat with the dehumidification heat exchanger as condensed water is repeatedly drained to the outside through the drainage channel. Since the foreign matter such as lint is received and captured by the projection provided as a part and the throttle part so that it does not flow first, foreign matter can be prevented from entering the drain pump without a filter, and the drainage channel The foreign material captured on the way remains, but does not cause clogging like the filter eyes.

  The air conditioning unit of the present invention dehumidifies and heats the air in the heat exchange area of the ventilation path from the suction inlet to the suction outlet in an air conditioning case having an air inlet and outlet. In the air conditioning unit in which the heat exchanger for dehumidification and the heat exchanger for heating are divided into a suction introduction side heat exchange area and a suction discharge side heat exchange area, the dehumidification heat exchanger is provided at the bottom of the heat exchange area. A dew condensation water drain tray provided to receive and drain the dew condensation water flowing down, a water collecting part for collecting and collecting water dripping or flowing down on the suction introduction side heat exchange area of the heat exchanger for dehumidification, and An auxiliary drainage tray that bypasses the outside of the dew condensation water drainage tray from a part of the water collection unit, passes through the dew condensation water drainage tray, leads the water collected in the water collection unit to the dew condensation water tray, and is drained This auxiliary drain pan and the condensed water drain Is another characterized in that a projection or stop portion of the baffle portion for receiving the foreign matter such as lint so as not to flow onward at least drainage aid drainage dish.

  In such a configuration, the suction introduction side heat exchange area and the suction discharge side heat are provided in the heat exchange area of the ventilation path formed between the opposed side walls of the air conditioning case between the suction air introduction port and the suction discharge port of the air conditioning case. Suction air can be dehumidified and heated by a dehumidifying heat exchanger and a heating heat exchanger that are partitioned into an exchange zone and continuously sent out as dry high-temperature air. In particular, the water in the air that exchanges heat with the dehumidification heat exchanger can be drained to the outside through the drainage channel by accepting the water separated as dew condensation water, and heat exchange on the suction side of the dehumidification heat exchanger Water that drops or flows down on the side of the basin is collected and collected in a water collection section, and a part of this water collection section leads to the condensation water drainage tray through an auxiliary drainage tray that bypasses the outside of the condensation water drainage tray. It can be drained without a drainage system, and in particular, it is attached to the intake side of the heat exchanger for dehumidification on the side of the heat exchange area on the suction introduction side, and it is easy to flow down with the condensed water. Since the foreign matter such as lint is received and captured so that it does not flow forward by projections or throttling parts provided as obstacles in the drainage channel of at least the auxiliary drainage tray, the foreign matter can enter the drainage pump without a filter. Prevent It can bets, but would still remains is the way contaminate trapped drainage channels, the maintenance-free not enough to cause clogging as the eyes of the filter. In the drainage channel of the condensed water drainage tray, a similar function can be obtained by providing a baffle if necessary.

  In the above, the auxiliary drainage tray may be characterized in that it is connected to the dew condensation water drainage tray at the throttle portion.

  In such a configuration, in addition to the above, in addition to the above, the auxiliary drainage tray also becomes a hindrance even in the throttle part that leads to the dew condensation water drainage tray and receives foreign matter such as lint and enters the dew condensation water drainage tray side that leads to the drainage system. Can be prevented.

  In the above, the heat exchanger for dehumidification and the heat exchanger for heating constitute a heat exchange section in which the fins are arranged in parallel, the heat exchanger for dehumidification is on the dew condensation water drain tray, and the heat exchanger for heating is an auxiliary. It can be characterized by being placed directly on a drain tray.

  In such a configuration, in addition to the above, the dehumidifying heat exchanger and the heating heat exchanger have the fins arranged side by side in parallel, and are wasteful in space between them, and the suction exhaust port for the flow of the circulating air The heat exchanger for dehumidification is placed directly on the dew condensation water drain tray and covered with debris, etc. or from the surroundings while avoiding the creation of an isolation space that causes bypass to the side. The auxiliary drainage tray can be operated using the lower space of the heating heat exchanger placed directly on it.

  In the above, the auxiliary drainage tray may be characterized in that it communicates with the bottom of the suction / discharge side heat exchange area of the heat exchange area.

  In such a configuration, in addition to the above, the auxiliary drainage tray leads to the bottom of the suction / discharge side heat exchange area of the heat exchange area, so that water enters the suction / discharge side heat exchange area for some reason. Even if there is, it can drain through the auxiliary drainage tray and the dew condensation water drainage tray.

  According to one feature of the air-conditioning unit of the present invention, water that has separated moisture in the air as condensed water at the time of dehumidification in the heat exchange area of the ventilation path is repeatedly drained to the outside through the drainage path. The protrusions and constrictions provided in this drainage channel catch and capture foreign matter such as lint so that it does not flow forward, and prevent foreign matter from entering the drainage pump without a filter. The failure can be avoided, and the foreign matter trapped in the middle of the drainage channel remains, but does not become clogged like the filter eyes.

  Further, according to another feature of the air conditioning unit of the present invention, water obtained by separating moisture in the air as dew condensation water by a dehumidifying heat exchanger is received in a dew condensation water drain tray and drained to the outside through the drainage channel. The water that drops or flows down to the suction-induction-side heat exchange area of the heat exchanger for dehumidification can be collected and collected in the water collection section, bypassing the outside of the condensed water drainage tray from a part of this water collection section. It can be led to the dew condensation water drainage tray through the auxiliary drain pan, and it can be drained without a dedicated drainage system.In particular, it adheres to the intake surface side of the heat exchanger for dehumidification and flows down along with the dew condensation water on the suction introduction side heat exchange area side. Corresponding to the easy thing, it catches and captures foreign matter such as lint so that it does not flow forward by the projection or throttle part as a baffle provided at least in the drainage channel of the auxiliary drainage tray and the dew condensation drainage tray. I repeat that Since the foreign matter such as lint is prevented from flowing forward by the projection or the restricting portion provided as a baffle in the drainage channel, it is possible to prevent the foreign matter from entering the drainage pump without a filter. However, although the foreign matter captured in the middle of the drainage channel remains, it does not cause clogging like the eyes of the filter and becomes maintenance-free. In the drainage channel of the condensed water drainage tray, a similar function can be obtained by providing a baffle if necessary.

  The water and foreign substances mentioned above include components of detergents and softeners that are separated by centrifugal action when air is sucked and introduced into the suction introduction side heat exchange area, and protrudes due to high viscosity. However, when diluted with water during drainage, the viscosity decreases and flows away with the drainage, so it does not continue to collect and the drainage pump is clogged or malfunctions. There is no cause.

  In addition to the above, the auxiliary drainage tray also prevents the foreign matter such as lint from getting into the condensate drainage tray side that leads to the drainage system by becoming a baffle even in the throttle part leading to the condensation drainage tray. be able to.

  In addition to the above, the heat exchanger for dehumidification and the heat exchanger for heating are wasteful in space between the fins arranged in parallel with each other, causing the bypass of the circulating air flow to the suction outlet side This contributes to space saving and high performance by avoiding the formation of an isolated space, and directly covers the dehumidifying heat exchanger on the dew condensation water drainage tray to cover the dew condensation water with lint etc. The auxiliary drainage tray can be operated without any special space by using the lower space of the heating heat exchanger placed directly on it.

  In addition to the above, if the auxiliary drainage tray communicates with the bottom of the suction / discharge side heat exchange area of the heat exchange area, even if water enters the suction / discharge side heat exchange area for some reason, Since drainage is performed through drainage trays and dew condensation drainage trays, the entire heat exchanging area can be used as a reservoir for drainage so that a large amount of water pools can be prevented from overflowing accidentally.

  The air conditioning / fan unit according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 15 for understanding of the present invention. The following description is a specific example of the present invention and does not limit the content of the claims.

  The air conditioning / fan unit 39 according to the embodiment of the present invention is an example when applied to the drum type washer / dryer 1 as shown in FIGS. 14 and 15, and is not limited thereto. The drum-type washing / drying machine 1 has a water tank 3 in a floating state in a washing / drying machine main body 44 by a suspension structure (not shown), and a rotating drum 2 formed in a bottomed cylindrical shape in the water tank 3 has an axial direction. Is inclined downward from the front side toward the back side. A clothing doorway 11 leading to the opening end of the rotary drum 2 is formed on the front side of the water tank 3, and a door 9 that closes the opening provided on the upward inclined surface formed on the front side of the washing and drying machine main body 44 so as to be openable and closable. The laundry can be taken in and out of the rotary drum 2 through the clothing entrance 11. Since the door 9 is provided on the upward inclined surface, the work for putting in and out the laundry can be performed without bending the waist.

  The rotating drum 2 is formed with a large number of through holes 8 communicating with the water tank 3 on its peripheral surface, and provided with stirring protrusions (not shown) at a plurality of circumferential positions on the inner peripheral surface. The rotating drum 2 is rotationally driven in the forward and reverse directions by a motor 7 attached to the back side of the water tank 3. Further, a water injection pipe 12 and a drain pipe 13 are connected to the water tank 3, and water is poured into and drained into the water tank 3 by control of a water injection valve and a drain valve (not shown).

  A control board provided on the inside of the rotary drum 2 by opening the door 9 and putting laundry and detergent into the rotary drum 2 and operating the operation panel 66 provided in the upper part of the front surface of the drum type washing and drying machine 1, for example. When the operation is started through control by 67 or the like, a predetermined amount of water is injected from the water injection pipe 12 into the water tank 3, and the rotary drum 2 is rotationally driven by the motor 7 to start the washing process. By the rotation of the rotating drum 2, the laundry accommodated in the rotating drum 2 is lifted in the rotating direction by the stirring protrusion provided on the inner peripheral wall of the rotating drum 2, and the stirring operation of dropping from the lifted appropriate height position Is repeated, so that the laundry has the effect of tapping and washing. After the required washing time, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation that rotates the rotating drum 2 at a high speed. Rinsing is performed by pouring water from the passage 12. Also in this rinsing step, the laundry stored in the rotary drum 2 is rinsed by repeating the stirring operation in which the laundry is lifted by the stirring protrusion by the rotation of the rotary drum 2 and dropped.

  The drum-type washing / drying machine 1 has a function of drying laundry stored in the rotary drum 2. Therefore, as described above, the drum-type washing / drying machine 1 sucks and exhausts the air in the air conditioning / fan unit 39 and the water tank 3 and introduces the air into the air conditioning / fan unit 39 to be dehumidified and heated. A circulation air passage 5 for blowing air again into the water tank 3 is built in, and a blower fan 15 is provided downstream of the air conditioning / fan unit 39 in the circulation air passage 5.

  When the blower fan 15 is rotationally driven, air flows in the circulation blower path 5 so that the damp air in the rotary drum 2 containing the laundry is circulated from the water tank 3 to the blower fan 15 through the through holes 8. The air is sucked and exhausted through the introduction pipe line 16. The exhausted moist air is introduced from the suction inlet 391 into the ventilation path 393 of the air conditioning / fan unit 39 located directly connected to the upstream side of the blower fan 15 and evaporated in the middle thereof. By dehumidifying the moisture in the air by condensing the water in the vessel 31 and heating by exchanging heat with the condenser 32, the air is always dry and hot. The dried high-temperature air is sucked into the blower fan 15 through the suction / discharge port 392 and then sent out to the blower conduit 33 to the water tank 3 to be blown into the water tank 3. The high-temperature dry air blown into the water tank 3 enters the rotary drum 2 through the through holes 8 and escapes to the water tank 3 while being exposed to laundry such as clothes, and is again introduced into the circulating air introduction pipe line 16. A drying process is implemented by the repetition of the circulation of the air in the above circulation ventilation path 5.

  In the drying process using the circulation air passage 5, foreign matter such as lint generated from laundry such as clothes is circulated in the air circulated through the circulation air passage 5, and the evaporator 31 and the condensation are circulated. It is difficult to carry out a drying process such as clogging of the vessel 32, biting into the rotating part of the blower fan 15, and accumulation on the inner surface of the blower fan 15, and frequent troublesome maintenance is required. In the middle of the circulation air flow path 5, specifically, the upstream side of the evaporator 31, the condenser 32, and the blower fan 15, and thus in the middle of the circulation air introduction pipe line 16, foreign matters in the circulation air are removed. It is common to provide a filter chamber 36 that houses the filter 35. Thus, even if foreign matter is mixed into the air after the laundry is dried and introduced into the circulating air introduction pipe 16 side on the evaporator 31 side, it is collected by the filter 35 when passing through the filter chamber 36. , It will not be mixed into the circulating air downstream. Therefore, the functions of the evaporator 31, the condenser 32, and the blower fan 15 are maintained for a long time. However, on the other hand, the collected foreign matter accumulates on the filter 35 in the filter chamber 36, and there is a problem that the passage resistance of the circulating air gradually increases and the drying function is deteriorated. It is provided so as to be detachable as in the case of. In addition, the air conditioning / fan unit 39 constitutes an air conditioning / fan unit 81 capable of handling them alone by being directly connected to the blower fan 15, but is not limited thereto.

  Here, the evaporator 31 in which condensed water is generated constitutes a heat exchanging unit 395 together with the condenser 32, and a condensed water storage unit 63 is provided in a range corresponding to a dehumidifying region at the bottom of the air conditioning case 38, and a drain pump 64. A drainage pipe 65 having a water level is connected, and drainage without excess or deficiency is performed based on detection of a water level by a water level sensor (not shown). However, if the water level rises abnormally due to some drainage abnormality, the stored dew condensation water may reach the other part of the circulation air flow path 5. For these reasons, the heat exchanging part 395 is provided so as to be positioned at the lowest part of the circulation air flow path 5.

  As described above, the air-conditioning / fan unit 39 mounted on various devices affects the increase in the size of the mounted devices, product price, maintenance effort, and running costs. Therefore, the size and the number of parts and the number of assembly steps are reduced. Reduction of replacement parts is desired. Corresponding to these, the air-conditioning / fan unit 39 of the present embodiment has a suction inlet port in an air-conditioning case 38 having a suction inlet port 391 and a suction outlet port 392, as shown in FIGS. A heat exchanging unit 395 including an evaporator 31 and a condenser 32 that dehumidifies and heats the circulating air and is located in the ventilation path 393 from the suction port 392 to the suction exhaust port 392, and a compressor that circulates refrigerant through the heat exchanging unit 395. 37, the air conditioning case 38 is composed of a plurality of, specifically, two upper and lower divided members 381 and 382, and the divided members 381 and 382 face each other on the outer surface of the air conditioning case 38. A sealing member 384 is continuously sandwiched between the dividing lines 383 to air-tighten the inside and outside of the air conditioning case 38 and collect on the outer wall of the water reservoir portion represented by the storage portion 63 described above of the air conditioning case 38. Although thereby draining are in stagnant water opened is provided to FIGS. 2, 3, drainage mechanism 101 as shown in FIG. 7 to prevent outside air sucked by.

  As described above, the air conditioning case 38 is composed of a plurality of divided members 381 and 382. The air conditioning case 38 is sandwiched between the dividing lines 383 formed by the divided members 381 and 382 facing the outer surface of the air conditioning case 38. With a simple seal structure that airtights the inside and outside of the case 38, the suction action is positive even if the ventilation path 393 from the suction inlet 391 to the suction outlet 392 communicates with the housing area 394 side of the compressor 37, for example. The functions of circulation, dehumidification, and heating of the suction air can be ensured without being affected by the accommodation area 394 that becomes an air reservoir. In addition, the drainage mechanism provided in the storage portion 63 of the air conditioning case 38 for a sudden water pool in the unlikely event of using the mutual communication between the ventilation path 393 and the accommodation area 394, regardless of the accommodation area 394 and the ventilation path 393. While 101 responds by being opened by the accumulated water and draining the accumulated water, it is possible to prevent the outside air from being sucked and to secure the function of introducing the circulating air and exchanging and discharging the heat.

  As a result, the compressor of the ventilation path 393 has a simple sealing structure in which the plurality of dividing members 381 and 382 constituting the air conditioning case 38 are sealed between the split lines 383 formed facing the outer surface of the air conditioning case 38 and the inside and outside of the unit are airtight. 37, while maintaining the functions of suction air circulation, dehumidification, and heating without the influence of communication with the storage area 394 side of the storage area 394, the storage section 63 can be configured without using the communication area 394 and the ventilation path 393. The drainage mechanism provided in the water reservoir represented by the storage portion 63 of the air conditioning case 38 is not limited to the normal drainage system mainly composed of condensed condensed water in the heat exchanging portion 395, but in the event of a sudden water pool. With 101, it is possible to cope with ensuring the function of introducing circulating air and exchanging and discharging heat, and the number of parts, the number of assembly steps, and the number of parts to be replaced are reduced by the number of seal points less than before. Because, product cost and running cost can be reduced both.

  In particular, when the air conditioning case 38 is configured by two divided members 381 and 382 as in the present embodiment, the number of members, the number of assembly steps, and the seal structure portion are further reduced.

  Also in the present embodiment, the housing area 394 and the ventilation path 393 are partitioned by the partitioning portion 386, but the seal structure is omitted. Because there is no seal structure in this way, even if the ventilation path 393 communicates with the accommodation area 394 side in both of the compartments, this compartment effect is combined and the accommodation area 394 has almost no suction action, The function of the suction air circulation, dehumidification and heating can be ensured more reliably and the performance can be improved. The partition portion 386 is formed by a butting structure of upper and lower partition walls 386a and 386b integrally formed on both the upper and lower divided members 381 and 382, and the air conditioning case 38 has a housing space 394 and a ventilation path 393 and has a complicated space. The shape body is realized with a simple configuration of two members. Moreover, instead of the upper and lower partition walls 386a and 386b, the partition portion 386 can be formed as a single partition wall integrally formed with one of the upper and lower split members 381 and 382.

  As shown in FIGS. 2, 3, and 7, the valve mechanism 101 has a drain port 101 a provided on the outer wall of a water pool portion such as the reservoir portion 63, and the drain port 101 a is externally exposed by a pulling pressure in the air conditioning case 38. The check valve 101b is provided on the outer wall of the water reservoir portion such as the storage portion 63 and closes the drain port 101a by the pulling pressure only when the pulling pressure is applied to the air conditioning case 38. While maintaining the function of the air-conditioning / fan unit 39 by shutting out the outside air with good airtightness, a large amount of water in case of emergency should be pushed open by its own weight and drained. It can be realized with a simple flap-type valve piece without closing behavior. Specifically, as a check valve 101b made of a rubber piece, a hook portion 101c integrally formed at the upper end thereof can be easily mounted by elastically engaging with a mounting hole 101d provided in the upper portion of the drain port 101a, and suction, Even when closing and releasing corresponding to suction release are frequent, the operation stroke is very small and does not promote fatigue, and it is extremely rare to become a replacement part for maintenance.

  In the present embodiment, in association with the communication structure of the ventilation path 393 and the accommodation area 394, a sudden water pool may reach the side of the accommodation area 394. Similar to the reservoir 63, the valve mechanism 101 is provided with the bottom of the accommodation area 394 as the water reservoir 396. As a result, even if the water pool once reaching the storage area 394 due to the height relationship between the ventilation path 393 and the storage area 394 is not eliminated on the storage section 63 side on the ventilation path 393 side, the water can be drained on the storage area 394 side. It becomes like this.

  Further, as shown in FIGS. 1, 4, 5, 11, and 12, the air conditioning case 38 has a suction inlet 391 at the rear of the ceiling wall at one end in the longitudinal direction and a suction exhaust at the end wall at the other end. It has a substantially rectangular parallelepiped shape provided with an outlet 392. As shown in FIG. 5, the compressor 37 is housed in a housing area 394 near the front portion on one end side in the air conditioning case 38, and the housing area 394, the rear side in the air conditioning case 38 with respect to the housing area 394 and others The upper and lower partition walls 386a and 386b extending from both the ventilation path 393 extending to the end side and the dividing members 381 and 382 forming the air conditioning case 38 and the partition wall extending from one side are partitioned. . Further, the evaporator 31 and the condenser 32 partition the heat exchange area 393a between the partition wall 386 and the end wall facing each other in the longitudinal direction of the air conditioning case 38 into the front and rear suction introduction sides and the suction discharge side. Is provided. Further, the suction inlet 391 opens upward higher than the ceiling wall of the heat exchange area 393a of the air conditioning case 38, and overhangs on the rear side of the accommodation area 394 in plan view as shown in FIGS. From the wrapping position to the size of the heat exchange area 393a in the ventilation path 393 and the one end side rear area 393b extended to the rear part of the accommodation area 394 on one end side of the air conditioning case 38, and without being bulky outward of the air conditioning case 38 Is provided. The ventilation path 393 further includes a longitudinally curved region 393c that smoothly connects from the base opening of the suction inlet 391 to the rear region 393b on one end side to guide the circulating air downward, and a rear suction introduction side of the heat exchange region 393a. A rear upward expansion region 393d extending upward from the suction introduction port 391 to the other end side of the air conditioning case 38 at a height less than the suction introduction port 391 is provided.

  Thereby, the front part of the one end of the air-conditioning case 38 between the suction inlet 391 provided in the rear part of the ceiling wall of the longitudinal direction one end of the air-conditioning case 38, and the suction discharge port 392 provided in the end-part wall of the other end The compressor 37 is accommodated at the side and the storage area 394 partitioned by the partitioning section 386 is excluded, and the circulating air is sucked from the suction inlet 391 without difficulty by the ventilation path 393 that is used almost fully in the longitudinal direction of the air conditioning case 38. It can be introduced and smoothly subjected to heat exchange in the heat exchanging unit 395 so as to be sucked and discharged to the suction / discharge port 392. At this time, the ventilation path 393 is configured so that the circulating air introduced from the suction inlet 391 is located at one end on the rear side of the air conditioning case 38 from the heat exchanging area 393a next to the housing area 394 as indicated by an arrow in FIG. Heat exchange installed in the heat exchange area 393a while being received by the suction introduction side, which is the rear part of the heat exchange area 393a, while being received by the heat transfer area 393a and the rear upward expansion part 393d that is deviated upward from the rear part of the heat exchange area 393a The heat exchange flow that passes almost evenly from the rear part to the front part of the evaporator 31 and the condenser 32 through the entire region of the evaporator 31 and the condenser 32 with the help of the filling effect by the uniform passage resistance by the evaporator 31 and the condenser 32 of the part 395. Can be generated. Therefore, the heat exchange efficiency is improved and the air conditioning function can be enhanced.

  In this case, in particular, the ventilation path 393 substantially overlaps the one end side rear area 393b of the ventilation path 393 from the position where the suction inlet 391 overlaps the rear side of the accommodation area 394 of the compressor 37 in plan view. Although the flow to the one end side rear region 393b having a smaller front-rear width than the suction introduction port 391 is reduced while increasing the introduction air volume of the circulating air due to the size, the turbulence and pressure loss are guided by the longitudinal curved path 393c. In addition to being introduced smoothly and directed toward the rear suction introduction side of the heat exchange area 393a, the rear upward expansion area where the introduced air extends from the suction inlet 391 to the other end of the air conditioning case 38 by the amount of the restriction. It can be made easier to flow into the 393d side. As a result, the uniform expansion of the circulating air introduced into the ventilation path 393 to the backward suction surface 395a of the heat exchange section 395 can be further promoted, and the heat exchange efficiency can be further enhanced. Further, as shown in FIG. 2, in the longitudinally curved path 393c, the flow of the suction-introducing air is bent, so that moisture removed from the accompanying laundry, detergent components and softener components that may have been mixed in Can be centrifuged, and the relief shape portion 393c1 shown by the phantom line that avoids interference with the upper end of the compressor 37 also receives a collision separation action.

  Here, as shown in FIGS. 2, 3, 4, and 5, the above-described storage unit 63 substantially coincides with the rectangular shape in plan view of the heat exchange unit 395 in the heat exchange region 393 a and is a heat exchange unit. It is formed as a dish-shaped heat exchange section receiving tray 393a1 that opens upward to receive 395. The heat exchanging unit 395 installed and received on the heat exchanging unit receiving tray 393a1 has a minute thermal separation gap (not shown) between the evaporator 31 and the condenser 32 by the fins 395c. The unit is formed as an integral unit, and heat transfer from the condenser 32 side to the evaporator 31 side is suppressed by the thermal separation gap, so that the growth of frost and ice in the evaporator 31 is suppressed. As the temperature rises, frost is melted so that high drying efficiency can be secured. Thereby, the isolation space previously provided between the evaporator 31 and the condenser 32 is omitted, so that the installation space is reduced, so that the size of the device can be increased and the performance can be improved without increasing the overall size. Moreover, bypass passage caused by play in the isolation space toward the suction / discharge port 392 side is suppressed, the effective area is kept large, dehumidification efficiency, heating efficiency, and drying efficiency are increased, and drying noise can be reduced. Here, even if the thermal separation gap is configured to be a space of a degree of separation that allows the evaporator 31 and the condenser 32 to be individually handled, the performance does not deteriorate significantly.

  Moreover, the heat exchanging portion 395 has one end where the facing distance between the suction surface 395a facing backward and the suction introduction side rear wall of the heat exchange area 393a of the air conditioning case 38 facing the suction surface 395a is connected to the suction introduction port 391. It arrange | positions in the diagonal direction as shown in FIG. 4, FIG. 5 with respect to the longitudinal direction of the air-conditioning case 38 so that it may become small toward the other end part side of the air-conditioning case 38 from the side rear part area | region 393b side. Thereby, the inclination angle of the direction of the fins 395c of the heat exchanging portion 395 with respect to the direction A shown in FIG. 4 in which the heat exchanging region 393a is inclined from the one end side rear region 393b side toward the suction / discharge port 392 is the shortest. Since θ is smaller than that in the case where the heat exchanging portion 395 is arranged in the longitudinal direction of the air conditioning case 38, the airflow resistance is further reduced by the smaller amount and the airflow distribution passing through the heat exchanging portion 395 is further increased. Since it is made uniform, both dehumidification efficiency and heating efficiency are further improved, and air conditioning performance, drying efficiency when installed in a washing dryer, and drying performance can be improved, and it is more silent.

  Here, the installation direction of the heat exchanging portion 395 is best matched with the heat exchanging region 393a as much as possible in the oblique direction A that is the shortest from the one end side rear region 393b toward the suction / discharge port 392.

  Further, as shown in FIG. 6, the heat exchanging area 393a is low on the suction discharge side of the heat exchanging part receiving tray 393a1 and the heat exchanging part 395 installed therein as the storage part 63, and on the suction air introduction side of the heat exchanging part 395 is high. The air conditioning case 38 is formed to have a bottom shape, and the storage area 394 is formed to have the bottom shape of the air conditioning case 38 so as to be lower than the storage portion 63 as shown in FIG. Thereby, the installation height of the compressor 37 in the air conditioning case 38 can be suppressed, and the center of gravity can be lowered.

  The heat exchanging part receiving tray 393a1 receives the heat exchanging part 395 by directly placing it without interposing a filter as shown in FIG. The portion of the heat exchanger 395 that receives the condenser 32 is partitioned from the portion that receives the evaporator 32, and the moisture and circulation system removed from the laundry accompanying the circulating air. The components of the detergent and softener that may get into the separation water drain tray 23 for separating and receiving and draining before passing through the heat exchanging section 395 are partitioned by a partition wall 28 that partitions each other. However, the drain port 22 is provided in the condensed water drain tray 21, and the separated water drain tray 23 is discharged through the condensed water drain tray 21.

  This is because the water in the circulating air is removed as condensed water by passing through the evaporator 31 and discharged from the condensed water drain tray 21, but there is no problem, but a detergent or softener with high viscosity that may enter the circulating air. When the component enters the heat exchanging part 395 or the blower fan 15, it adheres and narrows or clogs the air passage, or increases the rotational resistance of the blower fan 15. The purpose is to perform gas-liquid separation and drain water from the separated water drain tray 23 through the condensed water drain tray 21 without imposing a burden on the drain pump 64. Naturally, this gas-liquid separation also includes the water accompanying the circulating air, and the components of the highly viscous detergent and softener separated by gas-liquid are washed away with water that has been gas-liquid separated at the same time, diluted and drained. The pump 64 is advantageously not burdened.

  For this gas-liquid separation, the suction air introduction side of the heat exchange area 393a exchanges heat with the lower dividing member 382 of the air conditioning case 38 from the suction inlet 391 including the rear end area 393b on the one end side and the rear upward extension 393d. The air flowing downward between the rearward suction surface 395a of the part 395 and the rear wall of the air conditioning case 38 is temporarily received at the midway position in the height direction as shown in FIGS. 2, 3, and 5 of the heat exchange part 395. A shelf 24 extending substantially horizontally from the rear wall of the air conditioning case 38 to the front side so as to guide to the heat exchange unit 395 side, and inclined obliquely downward from the shelf 24 to the heat exchange unit receiving tray 393a1 Inclined portion that guides the suction-introduced air that passes through the shelf portion 24 through the entire rearward suction surface 395a of the heat exchange portion 395 that is installed on the heat exchange portion receiving tray 393a1 5 to form a.

  As a result, the suction air introduced into the ventilation path 393 collides with the shelf 24 while flowing downward from the suction introduction port 391 and the rear upward expansion portion 393d toward the heat exchange portion 395 and is guided to the heat exchange portion 395 side. However, the moisture removed from the laundry accompanying the suction air and the components of the detergent and softening agent that may enter the circulation system by the collision can be separated from the suction air. The components of the separated water, detergent and softening agent that have been separated move the shelf 24 toward the inclined portion 25 due to the flow of suction air, and flow down the inclined portion 25. Specifically, while the separated water is actively washed away to the inclined portion 25 side, the components of the highly viscous detergent and softener are washed away to reach the inclined portion 25 side, and then the gravity air is added to the flow of the suction air. As a result of the action of the above, it moves down the inclined portion 25. Separation water or the like flowing down the inclined portion 25 is blocked by the rib 26 shown in FIGS. 3 and 7 at the lower portion of the inclined portion 25, and one end side, in the illustrated example, the accommodation area 394 side leads to the separated water drainage tray 23. It escapes to the communication path 27 shown in FIGS. 1 and 7 and flows into the separated water drain tray 23.

  On the other hand, the bottoms of the heat exchanger receiving tray 393a1 and the entire storage portion 63 formed on the suction / discharge side are lowered toward the drain port 22 provided in the condensed water drain tray 21. In addition to this, the separated water drainage tray 23 has a minute communication portion 29 a on the partition wall 29 with the suction / discharge side, and has a minute communication portion 28 a on the partition wall 28 with the condensed water drainage plate 21. As a result, the separated water or the like that has flowed into the separated water drain tray 23 flows into the condensed water drain tray 21 through the communication portion 28 a, and then flows into the drain port 22 in the condensed water drain tray 21. In addition, water that may overflow or accumulate on the suction / exhaust side due to malfunction of the drain pump 64 connected to the drain port 22 flows into the separated water drain tray 23 through the communication portion 29a, and then communicates with the communication portion 28a. Flows to the dew condensation water drain tray 22 and reaches the drain outlet 22.

  Corresponding to the fact that the heat exchanging portion 395 is installed on the heat exchanging portion receiving tray 393a1 without providing the filter, the communicating portions 28a and 29a pass smoothly, but are mixed into yarn waste and circulating air. The components of detergents and softeners with high viscosity that may have passed are set so as not to pass through. Similarly, in the middle of the flow path of the condensed water drainage tray 22 and the separated water drainage tray 23, a throttle-type communication portion 41 and baffle protrusions 42 that do not allow the components of lint, detergent or softener to pass through are provided. Even if the thread waste is received by the communication portions 28a, 29a, 41 and the baffle protrusions 42, the total amount thereof is small, and normal drainage is not affected. On the contrary, the yarn waste that is received serves to receive the detergent components. Receiving the detergent component obstructs the passage of water, but the disturbed water accumulates and dilutes the detergent. Eventually, the diluted detergent is washed away to the drain port 22. Here, the components of the detergent and softening agent that may favor the circulating air are effectively separated before passing through the heat exchanging portion 395, together with the moisture removed from the laundry accompanying the circulating air, Since the water is drained after being diluted, the drain pump 64 is not burdened or stopped. Moreover, the communication part 41 is formed by cutting the middle part of the partition wall 41a crossing the flow path into a V shape, and reliably restricts the passage of the components of the thread waste, the detergent and the softening agent that are swept along the bottom part. However, even if the yarn waste restricted in the street is slightly bulky and restricts the passage of water, the communication portion 41 is said that the water restricted in the street becomes bulkier than the yarn waste. Since the degree of restriction of spreading upward is reduced, it can easily flow forward together with components such as a diluted detergent, so that it is not a problem.

  Further, the shelf 24 and the inclined portion 25 work effectively by narrowing the internal space of the rear half of the lower half of the air conditioning case 38. As a result, the rear wall of the lower half of the air conditioning case 38 is inwardly connected. 2 and FIG. 5 is provided, and the empty space S opened rearward and downward is formed below the shelf 24. When the air conditioning / fan unit 39 and the air conditioning / fan unit 81 are installed along the rear wall on the bottom of the washing machine main body 44 as shown in FIG. 1, the empty space S is as shown in FIGS. In addition, it can be effectively used as a wiring connection space outside the air conditioner / fan unit 39 and the air conditioner / fan unit 81, and a space for installing external devices such as sensors.

  The shelf 24 and the inclined portion 25 are integrally formed on the lower divided member 382 side so as to ensure the continuity, and the shelf 24 is located between the lower divided member 382 and the upper divided member 381. And formed at a position slightly below the joining flange 382a to be joined by forming a dividing line 383. The joining flange 382a accommodates an annular seal member 384 in a recess on the entire circumference thereof, and the seal member 384 is sandwiched by an uneven fitting in which the projection of the joining flange 381a of the upper split member 381 fits into the recess. The gap between the dividing lines 383 is sealed with a joining structure. The joining and sealing are firmly held by joining screws 381a and 382a by screw fastening portions 68 as shown in FIG. 3 using a number of fastening holes provided in the circumferential direction as shown in FIG.

  Here, the heat exchanging part 395 is arranged in the opening 51 formed between the upper and lower divided members 381 and 382 by the partition 386 between the ventilation path 393 and the containing area 394 on the side of the containing area 394 as shown in FIGS. 2, 4, and 5, a metal plate projecting back and forth as shown in FIGS. 2, 4, and 5, for example, an aluminum-based partition wall 52 with high corrosion resistance, is provided. By being inserted from above into a guide groove 51a formed in the mouth edge, in particular, a vertically-facing mouth edge, the end of the housing area 394 is positioned, and at the opening 51 portion of the ventilation path 393 and the housing area 394 It has a rough seal structure that suppresses airflow. The opposite end of the heat exchanging portion 395, that is, the end on the suction discharge port 392 side is the suction discharge port 392 side of the heat exchanging portion receiving tray 393a1 of the lower divided member 382 as shown in FIGS. Between the guides 53a and 53b integrally formed upward at the front and rear corner portions of the end portion of the end portion, the guide portions 53a and 53b are roughly fitted and positioned from above. By positioning these both end portions, the heat exchanging portion 395 is positioned at a predetermined position on the heat exchanging portion receiving tray 393a1. The heat exchanging portion 395 is also provided with a rib-like partition wall 54 as shown in FIG. 8 formed downward from the partition wall 386a to the other end portion wall facing the partition wall 386a on the back surface of the ceiling wall of the upper dividing member 381. The contact prevents the heat exchange part 395 from floating from the heat exchange part receiving tray 393a1 in cooperation with the upper edge of the opening 51 of the partition part 386. At the same time, the suction introduction air on the suction introduction side is prevented from bypassing from around the heat exchange section 395 to the suction discharge side in the heat exchange area 393a.

  Conventionally, the compressor 37 has legs that protrude laterally at three places around the bottom of the compressor, and is installed by fastening these legs to the bottom of the receiving area 394 with screws. Instead of the installation structure that has been made to absorb vibration by interposing an elastic vibration-absorbing material in the fastening portion, such a leg portion is omitted and seated via the elastic seat 43 in the recess 394a of the bottom 394c of the receiving area 394. It is elastically supported so that it can be buffered and absorbed. By omitting the legs, the compressor 37 itself can be reduced in size, weight, and cost. On the other hand, the omission of the leg portion makes it difficult to fix the compressor 37, and the compressor 37 resonates due to external vibration, particularly lateral vibration during dehydration, and excessive force is applied to the refrigerant pipe. As a result, the phenomenon that the pipe breaks or cracks are caused, and the elastic support by the seating on the recess 394a via the elastic seat body 43 exerts a vibration absorbing action against the vibration of the compressor 37. In addition, it exhibits a high buffering effect against lateral external vibration during dehydration. For example, the compressor 37, which has been bulky about 140 mm in plan view in the past, is reduced to about 90 mm, and the required space for the accommodation area 394 is reduced, so that the air conditioning case 38 has a conventional size and a ventilation path. It is possible to increase the heat exchanging efficiency by increasing the heat exchanging portion 395 and the heat exchanging portion 395 installed therein, thereby improving the air conditioning performance.

  Specifically, the storage area 394 is a water reservoir 396 as shown in FIGS. 1 and 2 for handling the overflow water described above, which is formed by the bottom of the lower division member 382 of the air conditioning case 38, or the like. In addition, the compressor 37 is seated in the recess 394a, which is a part of the recess 394a, as shown in FIG. As shown in FIGS. 1 and 8, a protrusion 145 protruding downward from the upper part of the upper dividing member 381 is opposed to the upper end of the compressor 37 with a predetermined gap 46 as shown in FIG. It is intended to prevent the excess from the recess 394a from exceeding the allowable amount. Specifically, the gap 45 is about 0.5 mm, for example, and the gap 46 is about 5 mm, for example. Here, the allowable amount of omission is a range in which the vibration absorption and buffering action for the compressor 37 is not impaired.

  As a result, the compressor 37 compresses the elastic seat 43 until it balances with the elastic supporting force of the elastic seat 43 by its own weight, settles in the recess 394a, and has some play in the radial direction and the vertical direction in the accommodation area 394. Have floating support. As shown in FIGS. 1, 3, and 9, the elastic seat body 43 has an annular leg portion 43 a that elastically supports the outer peripheral area of the lower surface of the compressor 37. Improves vibration absorption. Further, the leg portion 43a is restricted in its radial movement by fitting the lower end thereof into the concentric and shallow second concave portion 394b in the concave portion 394a, and the radial support force to the compressor 37 at the lower end portion. While increasing, the swing around the leg portion 43a of the compressor 37 is allowed to be somewhat allowed by the gap 45. The elastic seat body 43 further includes a cap portion 43b which is connected to the upper end of the leg portion 43a as shown in FIGS. Even if the vibration of the compressor 37 exceeds the gap 45 in any specific radial direction, the cap portion 43b is compressed in the specific radial direction corresponding to the inner periphery of the recess 394a, so that vibration absorption for vibrational vibration is performed. The effect is exerted, and a collision sound when vibration is transmitted to the air conditioning case 38 can be reduced. In addition, since the cap portion 43b is provided with axial ribs 43c on the outer periphery thereof, the cap portion 43b performs vibration absorption by compression with the inner periphery of the concave portion 394a flexibly and comfortably. The machine 37 is elastically supported so as to be positioned within a predetermined range in the recess 394a. Further, the cap portion 43b may be formed with an engaging recess as shown by an imaginary line in FIGS. 9 and 11 that engages with a part of the pipe protruding from the compressor 37 to the side of the body portion on the peripheral wall. Thus, the elastic seat 43 and the compressor 37 are prevented from rotating. Further, a non-rotating engaging portion or a fitting portion can also be provided between the elastic seat body 43 and the concave portion 394a. Further, the leg portion 43a and the cap portion 43b of the elastic seat 43 may be partially separated. In short, the basic condition is that the space between the recess 394a and the lower end of the compressor 37 is filled with an elastic member.

  As shown in FIG. 1, the storage area 394 is set so that the bottom 394c forming the recess 394a is slightly higher than the bottoms of the heat exchanger receiving tray 393a1 and the suction / discharge side 393a2. And the ventilation path 393 side are partitioned around the opening 51 sandwiching the heat exchanging part 395 by the partitioning part 386, and a recess is provided at the lower part of the lip of the opening 51 to separate the separated water on the ventilation path 393 side. A communication passage 47 connected to the drainage tray 23, specifically, the communication passage 27, is formed under the heat exchanging portion 395 of the bottom portion 394c. At the same time, a substantially annular rib 48 as shown in FIGS. 1, 2, 4, and 6 is formed on the bottom 394c by extending the inner peripheral wall of the recess 394a upward. Further, a part of the bottom portion 394c corresponds to the dew condensation water dropping portion from the low temperature pipe 37a around the compressor 37 so as to receive the dew condensation water. As a result, the condensed water that steadily drops from the low temperature pipe 37a during operation is received by the bottom 394c around the recess 394a, and at the same level as the bottom 394c at the lower portion of the opening edge of the opening 51 of the partition 386. By flowing down to the separated water drain tray 23 lower than the bottom portion 394a through the formed communication passage 47, it is naturally drained together with the separated water, and does not flow into the recess portion 394a by being obstructed by the rib 48. Therefore, in a conventional compressor with legs, it is essential that the portion facing the lower end of the compressor has a recess for floating the lower end of the compressor, relative to the portion where the leg is fastened through the elastic member. The condensate that is constantly dripping from the low-temperature piping of the compressor has been provided with a drain hole in the recess, but when the blower fan 15 is operated, suction from the ventilation path 393 side is accommodated. If it reaches the area 394, external air will be introduced through this hole, and there is a problem that the drying efficiency is deteriorated particularly at a low temperature, and it is necessary to improve the sealing performance between the ventilation path 393 and the accommodation area 394. A separate drainage system for guiding drainage from the constantly dripping hole to the normal drainage system is required. However, as described above, the dewatered water that drops on the bottom portion 394c of the storage area 394 is exclusively separated through the communication passage 47 provided by utilizing the fact that the seal between the ventilation path 393 and the storage area 394 is unnecessary. By draining to 23, there is no need for a drainage hole in the recess 394a on which the compressor 37 is seated, and the drainage path can be reduced, and since no outside air is sucked in, there is a problem of reducing the drying efficiency at low temperatures. Absent.

  Incidentally, the suction action from the downstream blower fan 15 to the suction / discharge port 392 is also performed on the discharge surface facing the front of the heat exchange unit 395 by the oblique arrangement of the heat exchange unit 395 with respect to the longitudinal direction of the air conditioning case 38 described above. There is no change in acting strongly on the side close to the suction / discharge port 392 with respect to the entire area 395b. For this reason, on the suction / discharge side of the heat exchanging area 393a, the dew condensation water generated when passing through the evaporator 31 from the side near the suction / discharge port 392 of the forward discharge surface 395b of the heat exchange section 395 is moved to the discharge surface 395b side. There is a concern that the air is sucked out and sucked into the blower fan 15 through the suction discharge port 392. To cope with this, in the present embodiment, as shown in FIG. 1, FIG. 4, FIG. 7, and FIG. 10, the front side of the end portion on the suction discharge port 392 side of the heat exchanging portion receiving tray 393a1 A shielding wall 56 that obstructs the suction of condensed water by a strong suction action from the suction / discharge port 392 is formed by using a guide 53a extending upward. In particular, the side of this strong suction action is provided in such a positional relationship that the blower fan 15 connected to the suction / discharge port 392 has a spiral casing 15b as shown in FIG. 13 and the blowing part 15d rises upward at the rear part. The shielding wall 56 corresponds to the corner portion along the lower half of the end edge on the suction discharge port 392 side of the discharge surface 395b of the heat exchange portion 395 and the front side of the lower end edge. 7. As shown in FIG. 11, the discharge surface 395b of the heat exchanging portion 395 can be covered to the minimum necessary with a simple shape including a guide 53a and formed in a stepped shape. Moreover, the stair-shaped shielding wall 56 exerts a strong suction force particularly on the lower end of the condenser 32 on the suction / discharge port 392 side, whereas the lower portion protrudes from the side to the discharge surface 395b side from the upper side. It has a staircase with a large amount. Thus, the suction from the suction / discharge port 392 is strong at the lower end of the discharge surface 395b of the condenser 32 on the suction / discharge port 392 side, and gradually becomes weaker toward the upper portion. Covers the suction discharge port 392 lower part of the condenser 32 larger than the upper part thereof, so that the suction is excessive or insufficient according to the strength of the suction force distribution that extends strongly from the suction discharge port 392 of the discharge surface 395b of the condenser 32. Can be limited without any restrictions.

  Further, the shielding wall 56 has an overhang edge including an inclination, a curve, etc. instead of the stepped shape, and is provided so as to protrude from the lower part or the side part around the discharge surface of the condenser. Projecting from the periphery of the condenser 32 toward the discharge surface 395b and obstructing strong suction from the suction / discharge port 392, the projecting edge has any one of an inclined shape, a curved shape, and a staircase. Thus, it is easy to adjust the amount of protrusion proportional to the degree to which the shielding wall 56 protrudes toward the discharge surface 395b of the condenser 32 and interferes with the strong suction from the suction / discharge port 392 to the strong suction strength distribution, and there is no excess or deficiency. Can be restricted.

  On the other hand, in order to prevent the shielding wall 56 from reducing the ventilation area of the discharge surface 395b as much as possible, the protruding portion 56a from the guide 53a is floated from the discharge surface 395b as shown in FIG. Thus, the shielding wall 56 projects to the discharge surface 395b side of the condenser 32 to cover strong suction from the suction / discharge port 392, and restricts strong suction from the suction / discharge port 392, but between the discharge surface 395b. By having the gap 111, the suction from the suction / discharge port 392 wraps around, so that the ventilation is not blocked in the range where the condenser 32 is covered by the shielding wall 56, and the function does not stop. Therefore, it is possible to avoid a situation where the working area of the condenser 32 is narrowed and the performance is reduced. In particular, the heat exchange in the entire region of the condenser 32 can be made uniform by the balance between the degree of restriction of strong suction by the shielding wall 56 and the degree of wraparound suction by the gap 111.

  At the same time, in the suction / discharge port 392 concentric with the fan 15a of the blower fan 15, the suction restriction side by the shielding wall 56 narrows the circular shape around the axis of the fan 15a of the suction / discharge port 392 as shown in FIG. It has a shape that has a vertical straight edge 392b and protrudes to the axial line side, so that it is easy to prevent the suction of water from the end of the heat exchange unit 395 on the suction / discharge port 392 side. Similarly, the lower edge of the suction / discharge port 392 is also formed as a horizontal straight edge 392c that narrows upward toward the axis up to the same height as the heat exchanging portion receiving tray 393a1, and restricts the suction of moisture from the bottom of the storage portion 63. .

  As shown in FIG. 1, the suction discharge port 392 of the air conditioning case 38 and the blower fan 15 are connected to the inner periphery of the suction discharge port 392 by connecting the connection cylinder 15c1 of the suction port 15c of the spiral casing 15b containing the fan 15a. The tip of the connection tube 15c1 is pressed against the flange wall 392a on the inner periphery of the suction / discharge port 392, and the spiral case 15b and the air conditioning case 38 are connected around the connection portion of the suction / discharge port 392 and the suction port 15c. By connecting portions 62 that are screwed at a plurality of locations, for example, at three or more locations, and maintaining the pressure contact state, the connection portions are simply sealed. Thereby, the seal member which becomes a consumable can be omitted, and both the product cost and the running cost are reduced.

  If the air conditioning case 38 is composed of three divided members, there is an advantage that the volume of each molded product is reduced, and it is easy to cope with a complicated shape. When applied to the illustrated example, with reference to FIG. 11, for example, in the upper divided member 381, the portion below the ceiling wall of the heat exchange region 303 a 1 and the higher portion, that is, the upward expansion region 393 d, suction introduction The upper portion of the mouth 391 and the accommodation area 394 is divided with a split line 61 facing the outer surface of the air-conditioning case 38 on a simple horizontal plane as shown by an imaginary line in FIG. If the inside and outside of the air-conditioning case 38 are sealed with a member interposed therebetween, the features obtained by the configuration of the three divided members can be obtained without impairing the features of the above-described embodiment of the two-divided structure.

  ADVANTAGE OF THE INVENTION According to this invention, the water produced or collected in the heat exchange area in an air-conditioning case can be drained without a filter, and a filter and its maintenance can be made unnecessary.
