JP 2007-68801 A

  In the conventional drum-type washing machine, the detergent charging unit 164 is provided in the gap between the water tank 163 and the upper plate 180a of the housing 180 in order to realize a compact product. In particular, in order to make the washing machine more compact in the height direction, a water injection path 166a that is formed on the top of the detergent charging unit 164 and for injecting water from above the detergent container 168 is provided on the upper plate 180a of the housing 180. It is provided close to the back side. In addition, the upper plate 180a of the housing 180 is provided with a water supply receiving port 167 connected to a water faucet or the like by a hose or the like, and a water supply valve 169 is provided below the water supply receiving port 167 inside the housing 180. ing.

  Here, the relative positional relationship between the water injection path 166a and the water supply valve 169 is such that the water injection path 166a provided closer to the back surface of the upper plate 180a of the housing 180 is closer to the water supply valve 169, as shown in FIGS. The relationship exists in a position higher than the water supply valve 169 provided slightly entering the inside of the housing 180. In this case, after completion of the water supply process (after the operation of the washing machine), when the water supply valve 169 is stopped, as shown in FIG. 19, residual water is connected to the connecting water channel 165a that connects the water supply valve 169 and the water injection channel 166a. Is likely to occur. When the remaining water is left for a long period of time, moisture always exists around the water supply valve 169, the connecting water channel 165a, and the water injection channel 166a, which causes mold. When the periphery of such a water channel is contaminated with mold or the like, there is a problem that it becomes impossible to wash with clean water, resulting in a decrease in the washing performance of the washing machine.

  The present invention has been made to solve the above-described problems, and provides a washing machine and a washing dryer that can effectively prevent mold around the water supply valve and maintain the washing performance of the washing machine. It is intended to provide.

  A washing machine according to one aspect of the present invention includes a housing, a water tank supported in the housing, a detergent charging section provided above the water tank, and water supply that communicates the detergent charging section and the water tank. A water supply valve that performs water supply control, and a water supply passage forming member that is connected to the water supply valve and forms a water supply passage for supplying water to the detergent charging unit, and is located at a position lower than the water supply valve. The water injection channel is formed.

  According to the above configuration, when detergent is introduced into the detergent introduction part and the water supply valve is opened, water is poured into the detergent introduction part through the water injection path formed by the water injection path forming member, It is mixed with water and supplied to the inside of the water tank through the water supply path. Here, in the present invention, the relative positional relationship between the water injection channel and the water supply valve is a relationship in which the water injection channel exists at a position lower than the water supply valve. Thereby, at the end of the water supply, water around the water supply valve is drained, and there is no residual water around the water supply valve. Therefore, generation of mold around the water supply valve can be effectively prevented. Therefore, it is possible to provide a washing machine that can supply clean water from the water supply valve and can maintain the washing performance of the washing machine.

  In the above-described configuration, it is preferable that the washing machine further includes a control board that controls the operation, and the control board is disposed in a space above the detergent charging unit in the housing.

  According to said structure, a control board is arrange | positioned using the space in the housing | casing formed above a detergent injection | throwing-in part effectively. That is, by forming the water injection path at a position lower than the water supply valve, the height position of the detergent charging part is lowered, and a space is formed between the detergent charging part and the upper plate of the housing. By arranging the substrate, a limited space in the housing can be effectively used. As a result, a compact design is possible without changing the overall size of the washing machine.

  In addition, since the control board is arranged further above the detergent charging part provided above the water tank, when maintenance is performed on the control board, a service person can easily perform maintenance while standing by opening the top of the housing. Operation is possible, and maintenance can be improved.

  Said structure WHEREIN: It is preferable that the said control board contains a thermal radiation part, and the said thermal radiation part is distribute | arranged close to the water injection path formation member which forms the said water injection path.

  In this case, since the water injection path forming member that forms the water injection path is cooled by the water that passes through the water injection path during water supply, by disposing the heat radiating portion of the control board close to the water injection path forming member, Heat generated on the control board can be effectively radiated. This facilitates the design of the control board in consideration of heat dissipation.

  Said structure WHEREIN: While the said thermal radiation part is provided in contact with the said water injection channel formation member, the said water injection channel formation member penetrates to the said thermal radiation part so that the water which passes the said water injection channel may contact the said thermal radiation part It is preferable that a hole is formed.

  According to this configuration, since the water passing through the water injection channel is in direct contact with the heat radiating portion of the control board, the heat generated on the control board can be radiated more effectively. In addition, since the temperature of the water injection passing through the water injection path rises and is injected into the water tank during the washing process, washing in a state where the liquid temperature of the cleaning liquid is increased is realized, and the cleaning performance is improved.

  In the above configuration, the washing machine further includes a check valve that allows a forward water flow from the detergent charging unit to the water tank, but prevents the reverse flow, and the check valve includes the water tank and the water supply. It is preferable to be provided at a connection portion with the path.

  According to said structure, since the non-return valve is provided in the connection part of a water tank and a water supply path (in other words, since the non-return valve is provided in the water tank side instead of the detergent injection part side), Even if the height of the detergent charging part is lower than before, a forward water flow from the detergent charging part to the water tank can be secured. That is, in the case where the check valve is provided on the side of the detergent inlet as in the prior art, there is a check valve at the outlet of the detergent inlet, so that the water (detergent mixed water) in the detergent inlet is non-returnable. A certain high head pressure is required to pass through the valve. Therefore, conventionally, in order to obtain this head pressure, the dimension in the height direction of the detergent charging portion could not be reduced. On the other hand, in the present invention, the check valve is not provided at the outlet of the detergent charging part, but the check valve is provided on the water tank side as described above. Even if the size is made smaller than before, the water flow in the forward direction from the detergent charging part to the water tank can be reliably ensured. The washing machine can be compactly designed by downsizing the detergent charging section.

  A washing / drying machine according to another aspect of the present invention includes a washing machine having any one of the above-described configurations, a drum rotatably mounted in the water tank, and drying air supplied to the drum. A drying mechanism for drying the clothes.

  According to said structure, it has a washing function and a drying function, and can implement | achieve the washing machine which can maintain washing | cleaning performance (washing performance) by preventing generation | occurrence | production of mold | fungi around a water supply valve effectively. .

  According to the present invention, generation of mold around the water supply valve and the water channel can be effectively prevented, and high cleaning performance can be maintained over a long period of time.

In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  FIG. 2 is a side sectional view of the drum type washing and drying machine according to the embodiment of the present invention.

  In FIG. 2, a cylindrical drum 3 having a bottom surface with a front opening that accommodates laundry is supported in a housing 1 and contained in a cylindrical water tank 2 that stores washing water. A drum drive motor 7 is attached to the rear surface of the water tank 2 to rotate the rotation axis of the drum 3 while tilting it forward. The water tank 2 is connected to a water supply pipe provided with a water supply valve (not shown) and a drain pipe provided with a drain valve.

  Further, the discharge port 11 is disposed on the upper side of the drum 3 so that the drying air after contacting the clothes can be effectively discharged upward. The discharge port 11 can be provided at a place other than the upper part of the drum 3, but is preferably provided above the water level of the washing water because it is affected by the washing water.

  Below the aquarium 2 is an illustration for supporting the aquarium 2 and attenuating vibration of the aquarium 2 when the drum 3 is rotated in a weight unbalanced state caused by uneven clothing in the drum 3 during dehydration or the like. There is no damper.

  As shown in FIG. 14, the front plate 1 e of the housing 1 is provided with a door body 5 so as to face the opening end side of the drum 3, and the user opens the door body 5 to open the drum 3. The laundry (clothing) can be taken in and out of the machine. In addition, an operation panel 4 that is elongated to the left and right and is provided with various operation keys and a display unit is provided on the upper portion of the front plate 1e of the housing 1, and a front drawer type detergent is placed below the side plate 1b. Part 10 is installed.

  As shown in FIGS. 6, 7 </ b> A, 10, and the like, a water supply receiving port 20 connected to a faucet or the like of a water supply by a hose or the like is provided at the upper rear of the washing / drying machine. Further, a water supply valve 14 connected to the water supply receiving port 20 and performing water supply control (control for stopping or supplying water from the water supply receiving port 20) is provided below the water supply receiving port 20 inside the housing 1. It has been.

  As shown in FIG. 1, the detergent charging part 10 is provided in the internal space of the housing 1 formed above the water tank 1 and can be pulled out to the detergent charging part frame 12 and the detergent charging part frame 12. And a detergent storage container 13 to be stored. The detergent container 13 is a substantially U-shaped box with a bottom having an opening at the top, a powder detergent container for housing powder detergent, and a liquid detergent container for storing liquid detergent. A three-compartment structure having a liquid finishing agent storage portion for storing the liquid finishing agent is provided. The detergent container 13 is not limited to the three-compartment structure as long as the detergent container 13 can store detergent.

  In addition, a water injection path forming member 16 that is connected to the water supply valve 14 and forms a water injection path 15 for supplying water to the detergent storage container 13 is provided above the detergent charging unit 10. In the present embodiment, the water injection path forming member 16 is disposed so that the water injection path 15 is formed at a position lower than the water supply valve 14. Thereby, the water around the water supply valve 14 is effectively drained at the end of the water supply, and a water supply structure in which no water remains around the water supply valve 14 is realized.

  The water injection path forming member 16 can form the water injection path 15 therein by thermally welding two resin molded plates made of, for example, polypropylene resin or the like. The water injection path forming member 16 includes a first water injection path for supplying water to the powder detergent container and the liquid detergent container, and a second water channel for supplying water to the liquid finish container. It can be set as the structure which forms. In this case, a water supply valve 14 for the first water supply channel and a water supply valve 14 for the second water supply channel are provided, respectively, and in the washing process, the powder detergent container is provided from the first water supply channel of the water injection channel forming member 16. While the water is supplied to the liquid detergent container, the rinsing process is configured to supply water from the second water injection channel of the water injection channel forming member 16 to the liquid finish agent container. Note that the material of the water injection channel forming member 16 and the configuration of the water injection channel are not limited to this, and any material can be selected in consideration of the ease of processing, etc., and it matches the compartment structure of the detergent container 13. Therefore, it is possible to design an appropriate irrigation channel.

  A plurality of water injection holes 19 are formed on the lower surface of the water injection path forming member 16 to move the water flowing through the water injection path 15 to the detergent container 13, and the water supplied from the water supply valve 14 passes through the water injection path 15. Then, water is poured from the water pouring hole 19 into the detergent container 13. Further, the water injected into the detergent container 13 is mixed with the detergent charged in the detergent container 13 and moves to the detergent charging unit frame 12.

  One end of a water supply hose 17 constituting a water supply path is connected to the bottom of the detergent charging unit frame 12, and the other end of the water supply hose 17 is connected to the water tank 2. Thereby, the water in the detergent charging unit frame 12 (water in which the detergent is mixed) is supplied to the water tank 2 through the water supply hose 17. In addition, a forward water flow from the detergent charging unit 10 to the water tank 2 is permitted at the connection portion between the water tank 2 and the water supply hose 17 (water supply path), while water and air are prevented from flowing in the reverse direction (reverse flow). A check valve 18 is provided. Thereby, in the washing process, it is possible to prevent the backflow of the washing water in the water tub 2 to the detergent charging unit 10, and it is possible to prevent the drying air from leaking from the water tank 2 through the water supply hose 17 in the drying process.

  Further, in the present embodiment, as shown in FIGS. 7 and 10 and the like, electrical and electronic parts (various circuits) necessary for controlling the washing / drying machine are provided above the detergent charging unit 10 in the housing 1. A mounted control board 50 is provided. For this reason, compared with the structure which provided the control board 50 in the lower part in the housing | casing 1, the lead wire which electrically connects the control board 50 and each member can be shortened. In addition, by providing the control board 50 at an easy-to-operate position on the upper front side in this way, the service person can perform the maintenance operation while standing from the front plate 1e side of the housing 1 during maintenance of the control board 50. And maintainability can be improved.

  The operation of the washing process and the like in the washing process (washing process, rinsing process, dehydration process) will be described below for the washing / drying machine configured as described above.

  When the washing process is started, the amount of laundry in the drum 3 is measured, and a necessary amount of detergent is displayed on the display unit of the operation panel 4. Thereafter, the user pulls out the detergent container 13 from the front plate 1 e of the housing 1 and puts the applied detergent (powder detergent or liquid detergent) or liquid finish into the detergent container 13. The type of detergent or the like introduced here is appropriately selected by the user, and may be one or all of them.

  Thereafter, the water supply valve 14 is opened and water supply is started. The water supplied from the water supply valve 14 passes through the water injection path 15 shown in FIG. 1, is injected into the detergent container 13 through the water injection hole 19, and is mixed with the detergent put in the detergent container 13. It becomes mixed water. In addition, the detergent mixture water flows from the detergent container 13 into the detergent inlet frame 12 and is finally supplied to the water tank 2 through the water supply hose 17 (water supply path). Then, after the supply of a predetermined amount of water corresponding to the amount of laundry is completed, the water supply valve 14 is closed, and a washing operation in which the drum 3 is driven to rotate is executed.

  Also in the rinsing process, the water supply valve 14 is opened, and the liquid finishing agent charged into the detergent container 13 is supplied to the water tank 2 at a predetermined timing. However, since it is similar to the washing process, the description thereof is omitted.

  After the washing process as described above, in the conventional configuration, residual water is generated around the water supply valve as shown in FIG. On the other hand, in the washing machine (washing and drying machine) according to the present embodiment, as shown in FIG. 1, the relative positional relationship between the water injection path 15 and the water supply valve 14 is such that the water supply path 15 supplies water. Since the relationship exists at a position lower than the valve 14, the water around the water supply valve 14 is drained at the end of the water supply, and there is no residual water around the water supply valve 14. Thereby, generation | occurrence | production of the mold | fungi around the water supply valve 14 can be prevented effectively. Therefore, it is possible to realize a washing machine that can always supply clean water from the water supply valve 14 and can maintain high cleaning performance over a long period of time.

  In addition, by forming the water injection path 15 at a position lower than the water supply valve 14, the height position of the detergent charging unit 10 is lowered, and a space is formed between the detergent charging unit 10 and the upper plate 1 e of the housing 1. However, the limited space in the housing 1 can be effectively used by arranging the control board 50 in the space. As a result, a compact design is possible without changing the overall size of the washing machine.

  In the washing and drying machine of the present embodiment, the check valve 18 is provided not on the detergent charging unit 10 side but on the water tank 2 side (connecting part between the water tank 2 and the water supply hose 17). The water flow in the forward direction from the detergent charging unit 10 to the water tank 2 can be secured even if the height of the water is lower than the conventional height. That is, in the conventional configuration, as shown in FIG. 18, the check valve 171 is provided on the detergent charging part 164 side (the connecting part between the detergent charging part frame 165 and the water supply hose 170). The check valve 171 is present at the discharge port 164. For this reason, in the conventional configuration, a certain amount of head pressure is required for the water (detergent mixed water) in the detergent charging unit 164 to pass through the check valve 171. Therefore, conventionally, in order to obtain this head pressure, there is a limit to reducing the dimension in the height direction of the detergent charging portion 164. On the other hand, in the washing and drying machine of the present embodiment, as shown in FIG. 1, the check valve 18 is not provided at the discharge port of the detergent charging unit 10, but the check valve 18 is disposed on the water tank 2 side as described above. Therefore, even if the size of the detergent charging unit 10 in the height direction is smaller than the conventional size, the water flow from the detergent charging unit 10 to the water supply hose 170 can be surely ensured. Moreover, the head pressure for water (detergent mixed water) to pass through the check valve 18 can be easily secured in the water supply hose 170. As described above, by reducing the size of the detergent charging unit 10 in the height direction and reducing the size of the detergent charging unit 10, a compact design of the washing and drying machine can be achieved. In addition, by reducing the height dimension of the detergent charging unit 10, there is a sufficient space for arranging the control board 50 and the like between the detergent charging unit 10 and the upper plate 1 e of the housing 1. The degree of freedom in design can be increased.

  Further, as shown in FIG. 15, the control board 50 includes a heat sink 50a (heat radiating portion) for radiating the heat generated in the board and lowering the board temperature. The heat sink 50a of the control board 50 is disposed close to the water injection path forming member 16 that forms the water injection path 15 (desirably, the heat sink 50a of the control board 50 is provided in contact with the water injection path forming member 16). Is). Since the water injection path forming member 16 is cooled by the water passing through the water injection path 15 during the water supply, the heat sink 50a of the control board 50 is disposed in the vicinity of the water injection path forming member 16 so that the control board 50 The generated heat can be effectively dissipated. Thereby, design of the control board 50 in consideration of heat dissipation becomes easy.

  Alternatively, as shown in FIG. 16, the heat sink 50a of the control board 50 is provided in contact with the water injection path forming member 16, and the water injection path forming member 16 is provided so that water passing through the water injection path 15 contacts the heat sink 50a. Is formed with a through hole 16a leading to the heat sink 50a. Thereby, since the water passing through the water injection path 15 directly contacts the heat sink 50a of the control board 50, the heat generated in the control board 50 can be radiated more effectively. In order to prevent water from leaking from the through hole 16a, it is desirable to seal between the water injection path forming member 16 and the heat sink 50a with a sealing material.

  The washing machine of the present embodiment is a washing / drying machine having not only a washing function but also a clothes drying function. Below, the drum type washing-drying machine which performs clothes drying of a heat pump system is demonstrated.

  As shown in FIGS. 3 to 6, the drum type washing and drying machine includes a heat pump device 30 that performs heat pump dehumidification and heating. FIG. 3 is a perspective view showing a cross section of a main part of the drum type washing and drying machine. FIG. 4 is a top view of an essential part of the drum type washing and drying machine. 5 is a vertical cross-sectional view taken along the line AA in FIG.

  As will be described in detail below, the drum-type washing and drying machine is configured such that the components forming the circulation path of the drying air centered on the heat pump device 30 are in a narrow space above the water tank 2 in the housing 1. It has a characteristic configuration that is centrally arranged. That is, as shown in FIG. 2 and FIG. 13, components such as the heat pump device 30 that are heavy objects are arranged in the upper space in the housing 1. And it has the support structure which supports components, such as the heat pump apparatus 30 which is heavy, in the upper space in the housing | casing 1, and has taken the countermeasure against a movement of a product (washing / drying machine) and a fall countermeasure. Details of the component support structure according to the present embodiment will be described later.

  As shown in FIGS. 3 to 5, the heat pump device 30 includes a compression unit 31 that compresses the refrigerant, a heat exchanger 80, an expansion valve that reduces the pressure of the high-pressure refrigerant, or a decompression unit that includes a capillary tube. Part 33. The heat exchanger 80 includes a heating unit 32 (heat radiation unit) that radiates heat of the refrigerant that has been compressed by the compression unit 31 to a high temperature and a high pressure, and a dehumidification unit 34 that takes heat from the surroundings by the refrigerant that has been decompressed and has a low pressure. (Endothermic part). The compression unit 31, the heating unit 32 and the dehumidifying unit 34 that constitute the heat exchanger 80, and the decompression unit 33 are connected by a pipe line 39 (FIG. 3), and are configured so that the refrigerant circulates through the pipe line 39. ing.

  The compression part 31 is arranged above the cylindrical outer peripheral surface of the water tank 2. And the compression part 31 is arrange | positioned so that the position of the bottom face 31a may become lower than the top part 2a of the bottom face of the water tank 2, as shown in FIG. Thus, the space formed in the upper part of the cylindrical outer peripheral surface of the water tank 2 is effectively used as the installation space for the compression unit 31 so that the heat pump device 30 including the compression unit 31 can be stored in a compact housing height. Can do. Thereby, even if the heat pump device 30 is installed in the upper part of the housing 1, it is possible to avoid an increase in the size of the clothes drying and washing machine in the height direction and to reduce the size of the device.

  The refrigerant compressed to a high temperature and high pressure by the compression unit 31 enters the heating unit 32, and heat is exchanged with the surrounding air (drying air passing through the circulation air path 8) to heat the air, and the refrigerant is cooled. To liquefy. The liquefied high-pressure refrigerant is decompressed by the decompression unit 33 to become a low-temperature and low-pressure liquid refrigerant, and then enters the dehumidifying unit 34 to exchange heat with the surrounding air to dehumidify and cool the air, and the refrigerant is heated. Then, the refrigerant returns to the compression unit 31 as a vapor refrigerant.

  On the other hand, the drying air sent out by the blower unit 9 enters the drum 3 through the water tank 2, dries the clothes in the drum 3 and enters the heat pump device 30 as humid air. In the heat pump device 30, the drying air is first dehumidified and cooled in the dehumidifying unit 34. Next, the drying air flows into the heating unit 32 and is heated to become high-temperature and low-humidity air, and returns to the blower unit 9.

  In the present embodiment, as shown in FIGS. 4 and 6, the air blowing unit 9 is fastened to the heat pump device 30 by the fastening member 38, and the air blowing unit 9 is arranged close to the side of the compression unit 31. It is installed. Thus, by effectively using the space formed on the side of the compression unit 31 in the housing 1 as the installation space for the air blowing unit 9, the air blowing unit 9 can be housed in a compact housing height. Thereby, even if the heat pump device 30 and the air blowing unit 9 are installed in the upper part of the housing 1, it is possible to avoid an increase in the size of the clothes washer / dryer in the height direction and to reduce the size of the device. .

  Further, in the washing / drying machine, lint generated in the laundry drying process adheres to the heat exchanger 80 and accumulates, resulting in clogging and a decrease in the heat exchange rate. Therefore, as shown in FIGS. 5 and 6, a filter unit 40 is provided on the upstream side of the heat exchanger 80 in the circulation air passage 8. The filter unit 40 collects foreign matters such as lint, dust and pollen mixed in the drying air when passing through the drum 3 before the drying air passes through the heat exchanger 80. This prevents the dust from entering the heat exchanger 80.

  As shown in FIG. 5, the filter unit 40 is provided on the downstream side of the first filter unit 40A and the first filter unit 40A that collects and collects dust having a predetermined size or more, and the first filter unit 40A. And a second filter portion 40B that collects and collects the fine lint and dust in the drying air that has passed through.

  As shown in FIG. 14, a filter opening 40c for attaching / detaching the first filter portion 40A is formed on the front surface side of the upper plate 1c of the housing 1, and the first filter portion 40A is a circulating air passage. 8 is configured to be detachable. For this reason, since a user or a service person can attach and detach the first filter unit 40A with respect to the casing 1 while standing from the front plate 1e side of the casing 1, the operability at the time of filter replacement is improved. be able to.

  On the other hand, as shown in FIG. 5, the second filter part 40 </ b> B is fixed in the circulation air path 8. That is, in the present embodiment, the first filter unit 40A is configured to be able to collect and collect almost all dust of a predetermined size or more, so the second filter unit 40B is configured as described above. It can be fixed to the circulation air passage 8. A heat exchanger 80 is disposed immediately upstream of the second filter portion 40B. The heat exchanger 80 is preferably configured so that it cannot be easily touched by a user or a service person. Therefore, in the present embodiment, the second filter unit 40B provided in front (upstream side) of the heat exchanger 80 is fixed in the circulation air passage 8 so that a user or a serviceman can attach to the heat exchanger 80. The structure cannot be easily touched. Furthermore, by fixing the second filter part 40B without making it detachable, it is possible to prevent lint leakage to the heat exchanger 80 due to misalignment of the second filter part 40B.

  Moreover, the filter part 40 which concerns on this Embodiment is provided in the upstream immediately before the heat exchanger 80, as shown in FIG.4 and FIG.5. Therefore, the velocity distribution of the drying air is smoothed and rectified by the pressure loss that the drying air receives when passing through the filter unit 40. By rectifying the drying air in the filter unit 40, the air path for guiding the drying air to the inlet of the heat exchanger 80 and rectifying it can be shortened. Since the rectified drying air is introduced into the heat exchanger 80, the heat exchange efficiency can be improved without causing large local unevenness in the heat exchange. Usually, when the circulation air passage is shortened and made compact, it is difficult to install a straightening mechanism such as a straight portion in the circulation air passage. However, in the present embodiment, by providing the filter unit 40 on the upstream side of the heat exchanger 80 as described above, the drying air is rectified without providing a straightening unit or the like in the circulation air passage. It has realized and shortened the circulation air path.

  Further, as shown in FIGS. 2 and 5, the filter unit 40 is provided in the vicinity of the air introduction surface side in the dehumidifying unit 34 of the heat exchanger 80. Therefore, since the drying air rectified by the filter unit 40 is sent substantially linearly to the dehumidifying unit 34 provided immediately upstream of the filter unit 40 through a short air passage, the dehumidified water splashes in the dehumidifying unit 34. Can be prevented. That is, the flow velocity of the drying air is suppressed by the air rectifying action of the filter unit 40, and immediately after that, the drying air flows into the dehumidifying unit 34 substantially linearly (without causing a drift due to the bending of the flow path). For this reason, since the situation where the flow of the drying air passing through the dehumidifying unit 34 locally has a high wind speed can be avoided, the splash of dehumidified water generated in the dehumidifying unit 34 can be effectively prevented. As a result, as shown in FIG. 5, the dehumidified water scattering prevention structure 35 provided in the lower part of the dehumidifying part 34 can be reduced in size, so that the size of the washing and drying machine can be reduced.

  The dehumidified water scattering prevention structure 35 includes a concave portion that is generated in the dehumidifying portion 34 and receives water droplets of dehumidified water that falls along the surface of the dehumidifying portion 34, and the concave portion is blown away by the wind pressure of the drying air. It is formed in a range that can catch the water droplets of dehumidified water. As described above, it is possible to effectively prevent the dehumidified water from splashing by the air rectifying action of the filter unit 40, so that it is possible to reduce the formation range of the recessed portion that receives the water droplets of the dehumidified water. Become.

  Further, when the dehumidified water collected in a state in which splashing is prevented by the dehumidified water splash preventing structure 35 is drained to the outside of the washing / drying machine (for example, in a drain port for washing liquid or the like provided below the housing 1) When draining), since the heat exchanger 80 is provided in the space above the water tank 2 in the housing 1, it is possible to easily drain using potential energy without using drainage means such as a pump. In this respect as well, the size of the washing / drying machine can be reduced.

  Moreover, the filter part 40 is provided in the upstream immediately before the heat exchanger 80, and it is possible to effectively prevent dust such as lint from flowing into the heat exchanger 80. Even if dust such as lint adheres to the heat exchanger 80 or accumulates in the heat exchanger 80 due to long-term use, the heat exchanger 80 is provided in the upper part in the housing 1, so that the accumulated lint, etc. During the maintenance for removing the dust, the service person can perform the maintenance operation while standing from the front plate 1 e side of the housing 1, so that the maintainability can be improved.

  Next, a configuration example of the filter unit 40 will be described in more detail with reference to FIG. The first filter portion 40A (filter) of the filter portion 40 has a substantially cylindrical shape, and the cylindrical peripheral surface is made of a mesh-like filter member having a predetermined roughness. A part of the cylindrical peripheral surface of the first filter portion 40A is opened as an inflow portion 41 for drying air, and the drying air discharged through the drum 3 passes from the inflow portion 41 to the first filter portion 40A. Flows into. On the other hand, the second filter portion 40B fixed downstream of the first filter portion 40A has a flat plate shape.

  A lid part 42 is provided on the upper part of the first filter part 40A. When the first filter part 40A is set in the washing and drying machine, the lid part 42 is formed on the upper plate 1c of the housing 1. The filter opening 40c is fitted. The lid portion 42 also functions as a handle member when the user attaches the first filter portion 40A.

Since the first filter portion 40A has a substantially cylindrical shape as described above, the flow passing through the filter portion is along the radial direction of the substantially cylindrical shape. That is, the pressure loss of the filter portion is such that the portion in which the flow direction of the drying air flowing into the filter portion matches the radial direction of the substantially cylindrical shape is relatively small, and thus the drying air that has flowed into the first filter portion 40A. The pressure loss distribution of the first filter portion 40A is relatively large in the upper and lower portions (region indicated by L _L in FIG. 5), and the central portion of the first filter portion 40A (in FIG. 5). L pressure loss than in the region) indicated by _S is reduced. When the drying air that has passed through the first filter part 40A having such a pressure loss distribution flows into the heat exchanger 80, the lower part of the dehumidifying part 34 has a relatively lower flow rate than the upper part. It has become so. As described above, the first filter portion 40A has a substantially cylindrical shape so that the lower part of the dehumidifying part 34 has a relatively lower flow rate than the upper part thereof, and this is provided in the vicinity of the air introduction surface of the dehumidifying part 34. It is preferable. Thereby, scattering of the dehumidification water which generate | occur | produces in the dehumidification part 34 can be suppressed more effectively. That is, the water droplets of the dehumidified water generated in the dehumidifying unit 34 are relatively small at the top of the dehumidifying unit 34, but the water droplets combine to drop gradually while falling down the surface of the dehumidifying unit 34, The lower part of the dehumidifying part 34 has larger droplets of water droplets adhering to the upper part. Since the lower part of the dehumidifying part 34 has a relatively slower flow rate of drying air than the upper part of the distribution of the size of the water droplets, the water droplet scattering range can be reduced as a result. is there. Therefore, the dehumidified water scattering prevention structure 35 provided below the dehumidifying part 34 can be made more compact.

  In the present embodiment, the filter unit 40 is exemplified by a two-stage filter including the first filter unit 40A and the second filter unit 40B. However, the filter unit 40 may be a one-stage filter or a three-stage or more filter. May be. Moreover, although the filter structure of the substantially cylindrical mesh was shown as the filter part 40, it is not limited to this, A flat plate shape or another shape filter may be sufficient.

  As described above, in the washing and drying machine of the present embodiment, both the filter unit 40 and the heat exchanger 80 of the heat pump device 30 are provided in the space above the water tank 2 in the housing 1, so Can be arranged. The filter unit 40, the heat exchanger 80, and the air blowing unit 9 are arranged in this order from the upstream side of the circulation air path 8, and heat the rectified drying air after passing through the filter unit 40. The drying air introduced into the exchanger 80 and dehumidified and heated by the heat exchanger 80 is blown to the drum 3 by the blower 9. Therefore, the washing and drying machine of the present embodiment has a conventional configuration (a heat pump device is provided in the space below the outer tub in the housing, while a filter is provided in the space above the outer tub in the housing, Compared to a configuration in which the filter, the air blower, and the heat exchanger are arranged in this order from the upstream side of the circulation air passage), the circulation air passage 8 through which the drying air is circulated can be shortened. As a result, a low pressure loss air passage can be formed, the power consumption of the blower 9 that blows the drying air in the circulation air passage 8 can be reduced, and the circulation air volume of the drying air is increased. It is possible. And even in the shortened circulation air passage, since the rectification of the drying air is realized and the heat exchange efficiency is increased, the heat exchange amount per unit time is significantly increased compared to the conventional configuration, In addition, power saving and drying time can be shortened.

  Moreover, the washing / drying machine of this Embodiment is provided with the 1st temperature sensor 36 and the 2nd temperature sensor 37 which detect the temperature of the air for drying in the circulation air path 8, as shown in FIG. The first temperature sensor 36 detects the drying air temperature before passing through the drum 3 and flowing into the heat exchanger 80. On the other hand, the second temperature sensor 37 detects the temperature of the drying air before being dehumidified and heated by the heat exchanger 80 and flowing into the drum 3. The detection outputs of the first and second temperature sensors 36 and 37 are used for controlling the heat pump device 30 and the like.

Here, the first temperature sensor 36 is provided between the filter unit 40 and the heat exchanger 80, and in particular, a region L _L (first filter unit) having a large pressure loss in the substantially cylindrical first filter unit 40A. It is provided in the vicinity of the upper part or the lower part of 40A. The region L _{L with} a large pressure loss in the first filter part 40A is less likely to be clogged with lint or the like than the region L _{S with} a smaller pressure loss. Thus, the first temperature sensor 36 provided in the vicinity of the area L _L is capable accurately detect the temperature of the dry air for a long period of time. In addition, when the filter unit 40 is clogged due to lint or the like, the detection temperature of the first temperature sensor 36 changes, and therefore the presence or absence of the filter unit 40 can be detected by the output of the first temperature sensor 36. Then, by providing the first temperature sensor 36 in the vicinity of the area L _L, the clogging of the filter unit 40, a long period of time, it is precisely detectable.

  The second temperature sensor 37 is provided on the downstream side of the air blowing unit 9. In the present embodiment, the first temperature sensor 36 and the second temperature sensor 37 can be compactly integrated in the circulation air passage 8 shortened as described above. And by shortening the circulation air path 8, temperature detection error factors, such as leak air, also reduce. Therefore, the first temperature sensor 36 and the second temperature sensor 37 provided in an integrated manner enable more accurate temperature detection with less influence of leaked air or the like.

  Next, a support mechanism for supporting the heat pump device 30 of the drum type washing / drying machine on the housing 1 will be described with reference to FIGS.

  The drum type washing and drying machine includes a first support member 61 and a second support member 62 that support the heat pump device 30 on both side plates 1 a and 1 b of the housing 1. As shown in FIGS. 8 and 9, the first support member 61 is installed between the side plates 1 a and 1 b so as to support the upstream end of the compression unit 31 in the heat pump device 30 from below. . On the other hand, the second support member 62 has a portion separated from the compression unit 31 in the heat pump device 30 from above through the filter unit 40 located at the upstream end of the component member that forms the circulation path of the drying air. It is constructed between both side plates 1a and 1b so as to support it.

  As shown in FIG. 7A, the heat pump device 30 is fixed to the first support member 61 by a screw 70 (fixing member) and a boss (not shown) that engages with the screw 70. The filter unit 40 and the control board 50 are fixed to the second support member 62 by screws 71 (see FIG. 6) and bosses 72 (see FIG. 7B) that engage with the screws 71.

  According to the support mechanism of the heat pump device 30 described above, the gravity of the compression portion 31 that is a heavy object is exerted on the side plates 1a and 1b via the first support member 61 that supports the vicinity of the compression portion 31 in the heat pump device 30. It will act in the vertically downward direction from above. As a result, the effect of suppressing the vibration amplitude by pressing the swing of the upper ends of the side plates 1a and 1b due to vibration with the gravity of the heat pump device 30 is generated. Further, since the weight of the heat pump device 30 is added to the vibration system including the side plates 1a and 1b, the weight of the vibration system including the side plates 1a and 1b is increased, and the vibration amplitude with respect to the same excitation force is suppressed. In this way, as a result of a large force acting vertically on the both side plates 1a and 1b of the housing 1 from above, vibrations of the side plates 1a and 1b of the housing 1 caused by rotation of the drum 3 and the like are suppressed. be able to. Thereby, the vibration of the whole housing | casing 1 can be reduced.

  According to the above support mechanism including the first support member 61, the casing generated by the rotation of the drum 3 or the like by pressing the both side plates 1 a and 1 b from above using the gravity of the heat pump device 30 including the compression unit 31. The vibration of the side plates 1a and 1b of the body 1 can be effectively suppressed.

  In addition, although the 1st support member 61 of this Embodiment is constructed between the both-sides plates 1a and 1b of the housing | casing 1, the gravity of the compression part 31 which is a heavy article is the 1st support member of this invention. If it is the structure which supports the heat pump apparatus 30 so that it may act on a perpendicular | vertical downward direction with respect to a side plate, it will not be limited to said structure. For example, as shown in FIGS. 11 and 12, as the first support member, a first support member 63 erected between the side plate 1a on the side where the compression portion 31 of the housing 1 is provided and the back plate 1d. May be used. That is, the first support member 63 is a corner formed by one side plate 1 a and the back plate 1 d of the housing 1, and is configured to support the vicinity of the compression unit 31 that is a heavy object in the heat pump device 30 from below. There may be. In this manner, if the heat pump device is supported by the corners of the strong side plate 1a and the back plate 1d, a support mechanism that can withstand an impact such as dropping or falling can be realized.

  Moreover, in this Embodiment, as above-mentioned, the ventilation part 9 is fastened with the heat pump apparatus 30 by the fastening member 38, and is arrange | positioned close to the side part of the compression part 31 (FIG. 4 or FIG. 6). reference). For this reason, in addition to the heat pump device 30, the side plate is pressed from above using the gravity of the air blowing unit 9, so that the vibration of the side plate of the housing 1 caused by the rotation of the drum can be effectively suppressed. In addition, since the compression unit 31 that is a heavy object and the blower unit 9 that is a heavy object are disposed in proximity to each other because it also includes a blower motor, the structure for supporting the compression unit 31 that is a heavy object Since the structure for supporting the air blowing unit 9 can be shared by the first support member 61 and the heavy object support structure can be simplified, the number of structural members can be reduced, the weight of the body can be reduced, and the cost can be reduced. Become.

  Furthermore, in the heat pump device 30, a portion of the heat pump device 30 that is separated from the compression unit 31 is also supported from above by the second support member 62.

  As described above, in the configuration in which the compression portion 31 that is a heavy object is provided at the rear end portion, the front side (such as the heat exchanger 80) other than the compression portion 31 in the heat pump device 30 is provided ( On the other hand, the upstream side will rise. Therefore, in the present embodiment, as described above, the heat pump device 30 is provided by the second support member 62 installed between the side plates 1a and 1b so as to suppress the lifting of the front side (upstream side) of the heat pump device 30. The front side (part of the heat pump device 30 separated from the compression unit 31) is supported via the filter unit 40. That is, the filter unit 40 is fastened to a front portion of the heat pump device 30 that is separated from the compression unit 31, and the second support member 62 is supported by supporting the filter unit 40 with the second support member 62. The front side of the heat pump device 30 is substantially supported from above via the filter unit 40. Thereby, the structure for supporting the lightweight part of the heat pump device 30 separated from the compression part 31 that is a heavy object and the structure for supporting the relatively light filter part 40 are shared by the second support member 62. It becomes possible to do. Therefore, the lightweight object support structure in the upper space in the housing 1 can be simplified, and the number of constituent members can be reduced, the body weight can be reduced, and the cost can be reduced.

  Furthermore, the structure which the 2nd support member 62 supports the heat pump apparatus 30 via the filter part 40 can support the site | part further spaced apart from the compression part 31 from upper direction. The greater the distance from the compression unit 31 that is a heavy object, the greater the force that acts in the direction of lifting, but the structure in which the second support member 62 supports from above in the region where the greater force acts in the direction of lifting more reliably. The heat pump device 30 can be supported.

  Of course, the front side of the heat pump device 30 may be directly supported by the second support member 62 from above without using the filter unit 40.

  With the support mechanism as described above, constituent members such as the heat pump device 30 provided in the upper space of the housing 1 are supported from below by the first support member 61 and supported from above by the second support member 62. Therefore, it can support stably with respect to the vibration of an up-down direction. Thereby, the vibration of the whole housing | casing 1 by rotation of the drum 3 can be reduced.

  In addition, the above-described support mechanism by the first support member 61 (or the support mechanism by the first support member 61 and the second support member 62) allows the washing / drying machine to be shipped as a product, transported, and installed in the process of being installed. Even when the product is accidentally dropped during movement, the supported member such as the heat pump device 30 can be reliably held without causing damage to the fixing member such as the screw 70. Hereinafter, this point will be described.

  As described above, in general, when a component is arranged in the upper space in the casing of the washing / drying machine, a support structure in which the upper surface of the component is supported by the support member is generally used. In this case, when a product is accidentally dropped, a fixing member (such as a screw) that fastens the component and the support member receives a tensile force due to the gravity of the component. For this reason, fixing members (such as screws or bosses tightened with screws) are easily damaged. In particular, as the weight of the part increases, the tensile force acting on the fixing member also increases, so that the fixing member is easily damaged.

  On the other hand, the support mechanism according to the present embodiment has a support structure in which the first support member 61 supports the vicinity of the compression unit 31 that is a heavy object in the heat pump device 30 from below. Thereby, even if it is a case where a washing dryer (product) falls accidentally, the heat pump apparatus 30 can be reliably supported by the 1st support member 61. FIG. That is, when the product falls by mistake, a large compressive force is applied to the first support member 61 from above due to the gravity of the heat pump device 30. At this time, a compressive force is also applied to a fixing member such as a screw 70 that fixes the heat pump device 30 to the first support member 61, but since the tensile force does not act, the fixing member is not damaged, and the heat pump device 30 is securely connected. It can be supported. Therefore, even if the heavy heat pump device 30 is arranged in the upper space in the housing 1, it is a highly reliable laundry that does not easily fail (the fixing member such as the screw 70 is broken) due to movement or dropping of the product. A dryer can be realized.

  In addition, since the compression part 31 vicinity which is a heavy article in the heat pump apparatus 30 is supported by the 1st support member 61 from the downward direction, the lightweight part spaced apart from the compression part 31 by using the support part by the 1st support member 61 as a rotating shaft Then the moment works in the direction of lifting. Here, since the second support member 62 supports the heat pump device 30 from above, a compressive force from below is applied to the second support member 62 and no tensile force acts. Therefore, in the second support member 62, the screw 71, the boss 72, and the like are not easily damaged.

  As described above, the vicinity of the compression unit 31 that is a heavy load is supported from below by the first support member 61, and the part of the heat pump device 30 that is separated from the compression unit 31 is supported from above by the second support member 62. Due to the structure, the heat pump device 30 can be more reliably supported in the upper space in the housing 1.

  Normally, when the component is supported from below in the upper space in the casing of the washing / drying machine, the distance between the water tank and the support member becomes closer by the amount of the support member. For this reason, the height of the entire washing and drying machine must be increased. However, in the washing and drying machine of the present embodiment, the drum 3 and the water tank 2 are provided with an inclination, and the space in the casing 1 (the space behind the upper part in the casing 1) generated by the inclination is used. In addition, by arranging the heat pump device 30, the height of the entire clothes dryer is suppressed. That is, in the present embodiment, the water tank 2 is inclined downward toward the rear, and the heat pump device 30 is disposed in a space in the housing 1 formed above the rear side (inclined lower side) of the water tank 2. Is arranged. Since a larger space is formed on the lower side of the water tank 2 than on the upper side of the water tank 2, the heat pump device 30 is arranged in this large space, so that the height of the entire washing and drying machine can be increased. The first support member 61 can be disposed on the lower surface of the heat pump device 30 without increasing the height.

  Further, in the present embodiment, since the heat pump device 30 is disposed above the water tank 2, the washing liquid at the time of washing does not enter the circulation air path 8, and copper, aluminum, or the like having good heat conduction is used. The dehumidifying part 34 and the heating part 32 made of metal can be prevented from being corroded by a detergent, a softener, a bleaching agent or the like in the washing liquid.

  Furthermore, in this Embodiment, it becomes a preferable structure by which the dehumidification part 34 and the heating part 32 which comprise the heat exchanger 80 are arrange | positioned substantially linearly with the ventilation part 9 along the air path of drying air. ing. In this case, it is possible to prevent the occurrence of drift due to the bending of the flow and further reduce the pressure loss of the drying air, and the drying air can be circulated without waste, so the drying air in the circulation air passage is blown. The power consumption of the air blower 9 can be reduced. Further, since it is possible to prevent the occurrence of uneven flow, it is possible to prevent the flow of the drying air passing through the dehumidifying unit 34 from locally becoming a high wind speed, so that the dehumidified water generated in the dehumidifying unit 34 is used for drying at a high wind speed. It is possible to prevent an inconvenient situation that the air scatters on the air, passes through the air blowing unit 9, returns to the drum 3, and wets the clothes.

  In addition, when the air volume of the drying air of the circulation air path 8 falls, the heat exchange amount between the dehumidifying part 34 and the drying air arranged in the circulation air path also falls. In this case, the refrigerant cannot be completely vaporized in the dehumidifying unit 34, so that the liquid refrigerant is compressed by the compression unit 31 in the next stage, and there is a risk of leading to failure of the compression unit 31. In the present embodiment, the above-described configuration can efficiently secure a desired air volume of the drying air in the circulation air passage 8, thereby avoiding the inconvenience that the liquid refrigerant is compressed by the compressor 31 and fails. This improves the reliability of the washer / dryer (or clothes dryer) using the heat pump device 30. And since dehumidification can be performed continuously without stopping the compression part 31 by the improvement in reliability, the drying operation time can be shortened.

  The blower unit 9 includes a blower motor 9a and a blower fan 9b. The blower unit 9 is provided with an inclined rotation shaft so that the blower motor 9a side is above the blower fan 9b. As a result, even if the dehumidified water is scattered to the blower unit 9, the dehumidified water adhering to the rotating shaft is dropped in a direction opposite to the motor 9b due to gravity and positioned above the position where the dehumidified water is scattered. It is possible to prevent moisture from entering the blowing motor 9b.

  In the present embodiment, the washing / drying machine having both the washing function and the clothes drying function has been described. However, the present invention is not limited to this and is also applied to a washing machine not having the clothes drying function. it can. As an example of the configuration of the washing machine, a configuration in which the clothes drying function is removed from the drum-type washing and drying machine illustrated in FIG. 2 (a configuration in which the heat pump device 30 and the like are excluded) can be used. Further, in the present embodiment, a configuration example of a drum type washing machine is shown, but a pulsator type washing machine may of course be used.

  Further, in the present embodiment, the washing / drying machine having the heat pump type heating / dehumidifying function has been described, but the washing / drying machine having a heating type heating function or a water cooling type or air cooling type dehumidifying function may be used. .

  The washing machine and the washing and drying machine according to the present invention can be suitably used for various washing machines such as a drum type and a pulsator system, and various washing and drying machines such as a heat pump system and a heater system.
