  The present invention incorporates a drying unit using a heat pump device in a heat source for drying clothes or the like, or a drying apparatus for storing an object to be dried such as clothes in a predetermined space and drying the space. The present invention relates to a washing / drying machine having a washing function for clothes and the like.

  As an example of the prior art, a laundry dryer for washing and drying clothes will be described.

  Conventionally, this type of washing and drying machine has a configuration as shown in FIG. Hereinafter, the configuration will be described.

  As shown in FIG. 17, the conventional washer / dryer is provided with a cylindrical water tank 103 elastically supported by a plurality of suspensions 102 inside a casing 101, and vibrations during washing and dehydration are caused by the suspensions 102. It is configured to absorb.

  In addition, a cylindrical, horizontal axis type rotating tank 105 that accommodates a so-called dry object 104 (hereinafter referred to as clothing 104) that is a target of washing or drying of clothes or the like is rotatably provided inside the water tank 103. Then, the rotation shaft 106a is rotated by the drive motor 106 to be rotated.

  A plurality of baffles (not shown) for stirring the clothes 104 are provided on the inner wall of the rotating tub 105, and a plurality of small holes 105 a are provided on the peripheral wall of the rotating tub 105.

  On the front surface of the housing 101, there are provided an opening 101a through which clothes 104 are taken in and out and a door 107 for opening and closing the opening. In addition, similar openings 103a and 105b are provided on the front side of the water tank 103 and the rotating tank 105, respectively, and the opening 103a of the water tank 103 is water-tightly connected to the opening 101a of the housing 101 by the bellows 108. ing.

  Further, the bottom of the water tank 103 has a drainage port 109 for discharging washing water, and the drainage port 109 is connected to a drainage hose 111 via a drainage valve 110, and its tip end is outside the washing and drying machine. Has been derived.

  The blower 112 blows and supplies the hot air heated by the heater 113 from the air supply port 114 into the rotary tank 105.

  The circulation duct 115 passes through the rotary tank 105 and the water tank 103 and dehumidifies the damp drying air. One end of the circulation duct 115 is connected to the exhaust port 116 at the bottom of the water tank 103 and the other end is connected to the blower 112. Yes.

  The water supply valve 117 controls water supply from a water supply hose 118 connected to a water tap (not shown) or the like.

  The operation of the conventional washing and drying machine configured as described above is as follows.

  When performing the washing operation, the door 107 is opened, the clothes 104 and the detergent are put into the rotating tub 105, and the operation is started.

In operation, first, the water supply valve 117 opens a water supply opening (not shown) on the washing water side, and the water tank 103 is opened.
When a predetermined amount of water is supplied into the rotary tank 105, the drive motor 106 is operated, and the rotary tank 105 is rotationally driven to perform a cleaning operation.

  After a predetermined time, the drive motor 106 is stopped, the drain valve 110 is opened, and dirty water is drained from the rotary tank 105 and the water tank 103 and drained to a drainage place outside the washing / drying machine via the drain hose 111.

  Next, water is supplied to the water tank 103 and the rotating tank 105 in the same manner as described above, and a rinsing operation is performed.

  When the rinsing is completed, the drain valve 110 is opened and drained, and then the rotating tub 105 is rotationally driven at a high speed by the drive motor 106, whereby the clothes 104 are dehydrated.

  When the washing / rinsing operation is completed as described above, the drying operation is started.

  In the drying process, the rotary tub 5 is driven to rotate at a low speed by the drive motor 106, and the hot air heated by the heater 113 is blown in the direction of arrow a by the blower 112 while stirring the clothes 104, and passes through the blower passage 120. The air is fed into the rotary tank 105 from the air supply port 114 as indicated by an arrow b.

  This hot air takes away moisture from the clothes 104, passes through the water tank 103 through the small hole 105 a of the rotary tank 105, and reaches the circulation duct 115 through the exhaust port 116.

  At this time, the water supply valve 117 opens a water supply port (not shown) on the cooling water side, and as a result, cooling water is poured into the circulation duct 115.

  Therefore, when the warm air containing moisture from the clothing 104 deprives moisture passes through the circulation duct 115, it is cooled by the cooling water to cause condensation of the moisture, and the wet warm air is dehumidified by the condensation, and the arrow c As shown in FIG.

  The cooling water and dew condensation water are drained out of the washing / drying machine via the drain valve 110.

  As described above, the conventional washing / drying machine circulates the hot air in the circulation path of the heater 113, the blower 112, the air supply port 114, the rotary tank 105, the water tank 103, the exhaust port 116, and the circulation duct 115, thereby rotating the rotary tank The garment 104 in 105 can be dried.

  However, in the configuration of the above conventional washer-dryer, the heat used for drying the clothes 104 is all discarded to the outside by the cooling water of the circulation duct 115 or the heat radiation from the housing 101, and is reused. It never happened.

  Therefore, a compressor that compresses the refrigerant, a radiator that dissipates the heat of the compressed refrigerant, a throttle means for reducing the pressure of the high-pressure refrigerant, and heat from the surroundings by the reduced-pressure and low-pressure refrigerant. It has been proposed that a heat pump device configured by connecting a depriving heat absorber with a pipe line so as to circulate the refrigerant is provided in the washing / drying machine (see, for example, Patent Document 1).

  According to this configuration, the moisture evaporated from the clothing is condensed on the heat absorber, so that the clothing can be efficiently dried, and the heat of the warm air containing moisture from the clothing is absorbed by the heat absorber. The heat of the refrigerant sent to the compressor via the refrigerant and warmed by the compressor is dissipated by the radiator, and the hot air can be reheated. Therefore, heat can be used effectively.

  In the dehydration step, the drain valve 10 is opened to drain the water in the outer tub 3 to the outside of the machine, and then the inner tub 5 containing the clothing 4 is rotated at high speed by the drive motor 6 to dehydrate.

Further, in the drying process, the inner tub 5 is rotated at a low speed by the drive motor 6 and the compressor 15 of the heat pump device 11 is operated. As a result, the clothes in the inner tub 5 are stirred up and down with the rotation of the inner tub 5, and the refrigerant in the refrigerant circulation circuit is compressed by the compressor 15, and this pressure causes the radiator 13 and the throttling. The valve 16 and the heat absorber 12 are circulated. In the radiator 13, heat is released from the high-pressure refrigerant, and in the heat absorber 12, the heat is absorbed by the refrigerant that is decompressed by the throttle valve 16 and becomes low pressure.

  When the wet warm air flowing into the heat absorber air passage 19 passes through the heat absorber 12, sensible heat and latent heat are taken away and dehumidified, and separated into dry air and dehumidified water. This dry air is heated again when passing through the radiator 13, flows as warm air to the blower 26, and circulates in the order described above.

  Further, the dehumidified water condensed by the heat absorber 12 is stored in the drain water container 22 and discharged from the discharge port to the outside of the apparatus.

  By repeating the above operation, drying of the garment 4 is advanced, and is appropriately terminated after a lapse of time.

  As described above, the heat absorbed by the heat absorber 12 using the heat pump device 11 is recovered by the refrigerant and is radiated again by the radiator 13, so that the clothing 4 can be given more heat than the energy input to the compressor 15.

The flow is from the discharge side air passage 25b to the discharge port 20b of the radiator air passage 20.

  By configuring the inside of the heat pump device 11 so that such an air flow is formed, a configuration that keeps the openings of the heat absorber 12 and the radiator 13 large can be obtained. In addition, the heat absorption side upper air passage 23a of the suction chamber 23 can be configured compactly without extending the air circuit portion of the heat pump device 11 more than necessary, for example, by extending it beyond the front width of the heat absorber 12.

The exhaust duct 29 is connected to the inlet 19 a of the heat sink air passage 19, and the air supply duct 27 is connected to the outlet 26 b of the blower 26. Are disposed on the side surfaces facing each other on the left and right sides of the casing 1, so that the components of the refrigerant circuit 18 and the air path components in the heat pump device 11 are arranged in the empty space at the lower rear of the casing 1. , Exhaust duct 29 and air supply duct The connection structure of bets 27, it is possible to minimize storage in the longitudinal direction.

  Further, if the suction side air passage 23b continuous with the suction chamber 23 and the discharge side air passage 25b continuous with the discharge chamber 25 communicate with each other, the substantially opposite directions of the heat absorber 12 and the radiator 13 that are substantially facing each other ( The airflow can be passed in the direction of arrow I in FIG. 3, and the airflow can flow over the entire width of the heat absorber 12 and the heat radiator 13 in the lateral direction without the airflow being deviated to one of the side surfaces. it can.

  Further, the opening width dimension h of the suction side air passage 23b continuous with the suction chamber 23 is made larger than approximately half of the height dimension W of the heat absorber 12, so that the heat absorber air path 19 above the compressor 15 is increased. As shown by the arrow II in FIG. 5 from the inflow port 19a, when the air flow is sucked into the suction chamber 23 in an obliquely upward direction, the air flow can also reach the lower part of the heat absorber 12 by the formation of the suction chamber 23. As a result, the airflow from the heat absorber air passage 19 can be effectively flowed.

  Therefore, the airflow facing from the entire height direction of the heat absorber 12 can be passed diagonally through the heat absorber 12 and the radiator 13 to the discharge side air passage 25b continuous with the discharge chamber 25. The radiator 13 can also exhibit predetermined dehumidifying performance and heating performance based on the opening area.

  Furthermore, by making the opening width dimension w of the heat absorption side upper air passage 23a continuous with the suction chamber 23 larger than substantially half of the width dimension W of the heat absorption element 12, as shown by the arrow II in FIG. When an airflow is sucked upwardly into the suction chamber 23 from the inlet 19 a of the airflow path 19, the airflow is generated in the suction chamber 23 due to the expansion of the volume by the heat absorption side upper airflow path 23 a and the suction chamber 23. Thus, the flow velocity is sufficiently decelerated, and the heat absorber 12 can pass through the heat absorber 12 in a substantially uniform state over the entire suction opening of the heat absorber 12.

  In other words, on the upstream side of the heat absorber 12, by providing the suction chamber 23 continuous with the suction side air passage 23 b and the heat absorption side upper air passage 23 a of the heat absorber 12, not from the front (front) of the heat absorber 12. Even if the airflow flows in from an offset direction (a direction substantially parallel to the suction side opening surface 12a) such as the heat absorption side upper air passage 23a and the suction side air passage 23b continuous with the suction chamber 23, the air Can flow in substantially uniformly. As a result, the pressure loss due to the collision of the airflow at the fin tips of the heat absorber 12 can be reduced, and the ventilation resistance of the heat absorber 12 can be kept low.

  As described above, according to the configuration of the first embodiment, the airflow flowing in from the inlet 19a of the heat absorber air passage 19 located in the left direction when viewed from the back side of the housing 1 shown in FIG. The heat absorption side upper air passage 23a and the suction side air passage 23b continuous with the chamber 23 communicate with large openings, sequentially pass through the heat absorber 12 and the heat radiator 13, and the rear side of the housing 1 shown in FIG. From the inlet 19a to the discharge side air passage 25b of the discharge chamber 25 communicating with the outlet 20b of the radiator air passage 20 located in the right direction opposite to the inlet 19a.

  The air flow can reduce the flow velocity while keeping the effective flow path cross-sectional areas of the heat absorber 12 and the heat radiator 13 in the heat exchange chamber 14 from the heat absorber air passage 19, and can be reduced in the heat absorber air passage 19. And the increase in the ventilation resistance of the heat absorber 12 can be suppressed.

Therefore, even when a small heat pump device 11 that can be accommodated in an empty space narrow in the front-rear direction at the rear lower portion of the casing 1 of the washing / drying machine 1x is configured to suppress an increase in ventilation resistance of the air passage in the heat pump device 11. It is possible to maintain a predetermined drying performance and suppress an increase in drying noise.

  Further, the connection between the blower 26 and the air supply duct 27 and the connection between the heat sink air passage 19 and the exhaust duct 29 are performed via the air supply hose 28 and the exhaust hose 30 which are elastic bodies. The flexibility of the mouth hose 28 and the outlet hose 30 can suppress the propagation of vibration to the outer tub 3 side during the drying operation of the heat pump device 11 including the compressor 15 and the blower 26.

  Accordingly, it is possible to prevent the installation floor from generating vibration and noise due to vibration propagation of the housing 1.

  Further, the clothes 4 move in the outer tub 3 during the drying operation or the like, and the outer tub 3 may be greatly displaced due to this movement. The large displacement is also caused by the air supply hose 28 and the exhaust hose 30 ( It can be absorbed by the elastic part).

  Therefore, the compressor 15 and piping supported by the vibration isolator (not shown) in the heat pump device 11 and the impeller (not shown) constituting the blower 26 come into contact with other structures. Therefore, it is possible to prevent abnormal noise from being generated or to be damaged by contact impact, and to improve reliability and durability.

  In the first embodiment, the arrangement of the compressor 15 and the blower 26 of the heat pump device 11 is maintained in a state where the configuration relationship between the heat absorber 12 and the suction chamber 23 and the configuration relationship between the radiator 13 and the discharge chamber 25 are maintained. In the same manner, the exhaust duct 29 and the air supply duct 27 can be expected to have the same effect as a configuration in which the exhaust duct 29 and the air supply duct 27 are arranged in the left-right direction as viewed from the back side of the housing 1 shown in FIG.

  That is, in the first embodiment, the heat absorber 12 and the heat radiator 13 are arranged vertically with respect to the horizontal direction of the housing 1, but in the second embodiment, the structure is shown in FIG. Thus, according to the inclination of the outer tub 3, the arrangement heights of the heat absorber 12 and the radiator 13 are made different so that the upper surface of the heat pump device 11 is in the same direction as the rear surface inclination direction of the outer tub 3. is there.

As a result, it is possible to use a heat exchanger that is slightly larger than the configuration shown in the first embodiment.

  Furthermore, the inclination of the heat absorber 12 and the heat radiator 13 can ensure a large volume of the heat absorption side upper air passage 23a particularly in the suction chamber 23. As a result, the heat absorber air passage 19 flowing into the heat pump device 11 can be The wind speed of the airflow can be further reduced. Therefore, the distribution of the airflow flowing through the heat absorber 12 can be made substantially uniform throughout, and improvement in drying efficiency can be expected.

FIG. 13 is a rear view of the washing / drying machine in which the heat pump device and the blower are mounted in different arrangements. Here, the same constituent elements as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Therefore, the following will be described focusing on differences from the first embodiment.

  10 and 11, the difference from the first embodiment is that the blower 26 directly connected to the outlet 20b of the radiator air passage 20 in the first embodiment is separated and the outlet 20b is formed in a duct shape. The outlet 20b is open at the top of the heat pump device 11 in communication with the discharge side air passage 25b of the discharge chamber 25.

  By adopting such a configuration, the blower 26 can be disposed at a position away from the heat pump device 11 as shown in FIG. 12, so that the same effects as those of the first embodiment can be obtained. The degree of freedom is increased in the arrangement of the device 11 and the blower 26, and integration corresponding to the configuration of the washing / drying machine 1x becomes possible.

Note that the same constituent elements as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Therefore, the following will be described focusing on differences from the first embodiment.

  As shown in FIG. 14, the difference from the first embodiment is that the depth dimension of the suction chamber 33 in the front-rear direction of the housing 1 (distance facing the suction side opening surface of the heat absorber 12) The point is that the suction side air passage 33b communicating with the inlet 19a of the passage 19 is made larger toward the side.

With this configuration, the ventilation resistance on the suction side air passage 33b side where the suction chamber 33 is opened in the heat sink air passage 19 is lower than the ventilation resistance on the suction side air passage 33d side in the reverse direction, and as a result, the arrow III As shown, the air flow on the suction side air passage 33b side easily flows, the distribution of the air flow in the lateral direction on the suction side opening surface 12a side is made more uniform, and the dehumidification and heating performance of the heat absorber 12 and the heat radiator 13 are improved.

Note that the same constituent elements as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Therefore, the following will be described focusing on differences from the first embodiment.

  As shown in FIG. 15, the difference from the first embodiment is that the heat absorber 12 is disposed so that the suction side air passage 34 b side continuous with the suction chamber 34 is gradually separated from the substantially forward direction of the housing 1. However, the radiator 13 is also arranged in parallel with this.

  In other words, in this configuration, the heat exchange chamber 14 is inclined so that the distance of the suction chamber 34 facing the suction side opening surface 12a of the heat absorber 12 becomes shorter as the distance from the suction side air passage 34b increases. It is.

  With this configuration, since the airflow flowing diagonally toward the discharge side air passage 35b continuous with the discharge chamber 35 in the radiator air passage 20 is closer to the front side with respect to the heat absorber 12 and the heat radiator 13, the suction chamber 34, the distribution of the airflow in the lateral direction (substantially parallel to the suction side opening surface 12a) on the suction side opening surface 12a is made more uniform without increasing the ventilation resistance from 34 to the discharge chamber 35. 13 dehumidification and heating performance can be improved.
