The machine 20 is accommodated in the heat exchange air passage 26 along with the heat absorber 23 and the radiator 21. The inlet side of the heat exchange air passage 26 communicates with the upstream circulation air passage outlet 16, and the outlet side communicates with the downstream circulation air passage inlet 18.

  As shown by an arrow 27 in FIG. 3, the drying air blown by the blower 12 passes through the upstream circulation air passage 14, passes through the heat absorber 23 and the radiator 21 in the heat exchange air passage 26, and then downstream. After passing through the side circulation air passage 17 and entering the outer tub 3 and the inner tub 5 from the outlet 19 and passing through the clothing 4 in the inner tub 5, it returns to the blower 12 again through the outer tub outlet 13 and circulates. It is supposed to be. That is, the outer tub 3, the upstream circulation air passage 14, the heat exchange air passage 26, and the downstream circulation air passage 17 form a circulation air passage for drying air.

  The upstream circulation air passage 14 from the outer tub 3 to the heat absorber 23 is provided with an exhaust port 28 on the upper surface of the main body 1 for exhausting the air flowing therethrough to the outside of the main body 1.

  A filter 33 made of a synthetic fiber net or the like is detachably provided as a filter means for removing foreign substances in the air in the middle of the exhaust port 28 and the intake port 31 of the upstream circulation air passage 14.

  The downstream circulation air passage inlet 18 and the heat exchange air passage outlet 26a communicate with each other via an air supply hose 34 made of a bellows-like stretchable flexible material, and the outer tank outlet 13 and the upstream circulation air passage inlet. Similarly, 15 communicates via an exhaust hose 35 made of a bellows-like stretchable flexible material to prevent the vibration of the outer tub 3 from being transmitted to the heat pump device 25. Further, a drain water container 36 for storing dehumidified water from the heat absorber 23 is provided at the lower part of the heat exchange air passage 26, and the water stored in the drain water container 36 is discharged from the drainage pump 37 to the outside of the machine body. The

  As shown in FIG. 3, the heat pump device 25 includes a compressor 20, a radiator 21 that radiates the heat of the compressed refrigerant, and a pressure reducing means that includes a throttle valve, a capillary tube, and the like for reducing the pressure of the high-pressure refrigerant. 22 and a refrigerant that has been depressurized to a low pressure are connected by a pipe 24 so that the refrigerant circulates through a heat absorber 23 that takes heat away from the surroundings, and the refrigerant flows in the direction of the arrow 38 and circulates. Realize the cycle. The control means 39 controls the washing, dehydrating and drying processes by driving the drive motor 6, the drain valve 10, the blower 12, the compressor 20, the intake valve 32, and the like.

  In the above configuration, this operation will be described next. In the washing process, water is supplied until the water level reaches a predetermined water level in the outer tub 3 with the drain valve 10 closed, and the garment 4 and the inner tub 5 containing the washing water are rotated by the drive motor 6 to wash the clothing 4. I do. In the rinsing step after washing, water is supplied into the outer tub 3 as in the washing step, and the garment 4 is rinsed by rotating the inner tub 5. In the dehydration step, the drain valve 10 is opened to drain water 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.

  In the drying process, when the compressor 20 of the heat pump device 25 is operated, the refrigerant is compressed, and this pressure circulates through the radiator 21, the decompression means 22, and the heat absorber 23. The heat of the refrigerant compression is released in the radiator 21, and the heat is absorbed in the heat absorber 23 by the refrigerant that has been decompressed by the decompression means 22 to a low pressure. At this time, the blower 12 is activated, and the warm air heated by the heat radiation of the radiator 21 is blown into the outer tub 3 and the inner tub 5 from the outlet 19 through the downstream circulation air passage 17. The inner tub 5 is rotationally driven by the drive motor 6 and the clothes 4 are agitated.

  The warm air blown into the inner tub 5 deprives moisture when passing through the gaps in the clothing 4, passes through the outer circulator exhaust port 13 of the outer tub 3 through the upstream circulation air passage 14 in a wet state, The exchange air path 26 is reached. When the wet warm air passes through the heat absorber 23, sensible heat and latent heat are taken away and dehumidified, and separated into low-temperature air and dehumidified water. This low-temperature air is heated again by the radiator 21 and becomes warm air with low relative humidity. At this time, the intake valve 32 is controlled to be closed, the intake port 31 is closed, and the drying air circulates through the inner tank 5, the downstream circulation air passage 17, the upstream circulation air passage 14, and the heat pump device 25. The dehumidified water condensed by the heat absorber 23 is stored in the drain water container 36 and discharged from the drain pump 37 to the outside of the main body 1. By repeating the above operation, drying of the garment 4 proceeds.

  Next, the case where the clothes hung on the place where the washing / drying machine is installed (here, the bathroom including the bathroom) is dried will be described. The blower 12 is operated with the intake valve 32 and the louver 30 opened. Along with the operation of the blower 12, the pressure loss of the filter 33 causes the intake port 31 existing on the suction port side of the blower 12 to have a negative pressure with respect to the atmosphere, and the exhaust port 28 has a positive pressure with respect to the atmosphere. Is taken into the downstream circulating air passage 14 from the air inlet 31, passes through the heat pump device 25, passes through the inner tank 5 and the outer tank 3, and is discharged out of the main body 1 from the exhaust port 28.

  The outside air that has entered the main body 1 from the air inlet 31 flows through the heat pump device 25, is cooled and dehumidified by the heat absorber 23, is heated by the radiator 21, and is discharged from the exhaust port 28 as very dry dry air. Is done. As described above, since the dry air is discharged out of the main body 1 while dehumidifying the air at the place where the washing / drying machine is installed, drying of clothes hung in the bathroom or bathroom is promoted.

  In addition, when clothes are hung near the main body 1, the exhaust port 28 is on the upper surface of the main body 1, so that by adjusting the angle of the louver 30 and directly applying dry air from the exhaust port 28 to the clothing, Furthermore, it can dry in a short time.

  Further, when washing or drying is not performed in the inner tub 5, low-humidity and high-temperature drying air can be passed through the inner tub 5 and the outer tub 3, so that the dehumidification of the bathroom including the bathroom can be performed. In addition to hanging clothes, the inside of the outer tub 3 can be dried, and the occurrence of mold in the outer tub 3 can be suppressed.

(Embodiment 2)
FIG. 4 is a sectional view of the washing / drying machine according to the second embodiment of the present invention, FIG. 5 is a rear view of the washing / drying machine, and FIG. 6 shows the configuration of the heat pump device of the washing / drying machine and the flow of drying air. It is a system conceptual diagram shown. The same constituent elements as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, only the inlet port 31 is provided in the upstream circulation air passage 14, and the exhaust port 28 is provided in the exhaust air passage 40 branched from the heat exchange air passage outlet 26a. A branch valve 41 composed of a two-way valve is provided at the branch point between the exhaust air passage 40 and the downstream circulation air passage 17 so that the air coming out from the heat exchange air passage outlet 26a flows to the downstream circulation air passage 17 side. The flow to the exhaust air passage 40 side can be switched.

  In the above configuration, this operation will be described next. In the normal drying process in which the clothes 4 are put in the inner tub 5, the control means 39 closes the intake valve 32 and switches the branch valve 41 to the downstream circulation air passage 17 side to perform the drying operation. Accordingly, the drying air circulates through the inner tank 5, the downstream circulation air passage 17, the upstream circulation air passage 14, and the heat pump device 25. The dehumidified water condensed by the heat absorber 23 is stored in the drain water container 36 and discharged from the drain pump 37 to the outside of the main body 1. By repeating the above operation, drying of the garment 4 proceeds.

  Next, when drying the clothes hung in the place where the washing and drying machine is installed, when the user selects the hanging drying process, the control means 39 opens the intake valve 32 and opens the branch valve. 41 is switched to the exhaust air passage 40 side to perform the drying operation. As a result, the intake port 31 has a negative pressure with respect to the atmosphere and the exhaust port 28 has a positive pressure with respect to the atmosphere with the operation of the blower 12, so that the outside air enters the downstream circulation air passage 14 from the intake port 31. The air is taken in, passes through the heat pump device 25 and the branch valve 41, and is discharged from the exhaust port 28 to the outside of the main body 1 through the exhaust air passage 40.

  Outside air that has entered the main body 1 from the air inlet 31 flows through the heat pump device 25, is cooled and dehumidified by the heat absorber 23, is then heated by the radiator 21, and is dried dry air to be discharged from the exhaust port 28. . As described above, since the dry air is discharged out of the main body 1 while dehumidifying the air at the place where the washing / drying machine is installed, drying of clothes hung in the bathroom or bathroom is promoted.

  Next, after finishing the washing process and the dehydrating process, a case will be described in which some clothes are dried in the inner tub 5 and some clothes are hung in a bathroom or bathroom for drying. This is the case when, for example, underwear that is not worried about dry wrinkles and a cutter shirt that is worried about dry wrinkles are washed at the same time. Etc. corresponds to the case of taking out and hanging it off.

  The washing and drying machine of the present embodiment has three drying control modes corresponding to the case where the drying in the inner tub 5 and the hanging drying are performed simultaneously.

  In the first drying control mode, the control means 39 opens the intake valve 32, the branch valve 41 adjusts the control position, and the dry air flows to both the downstream circulation air passage 17 and the exhaust air passage 40 side. Perform the drying operation in the state. As a result, a part of the drying air flows through the circulation air passage, and a part of the air is exhausted out of the main body 1 through the exhaust port 28, so that the clothes hung in the bathroom and bathroom and the inner tub 5 The clothes 4 can be simultaneously dried. However, in this mode, the air volume of the drying air flowing through the circulation air passage and the drying air discharged to the outside of the main body 1 is smaller than that in the single drying step described above, so that the inside of the inner tub 5 and the suspended clothing There is a disadvantage that both drying times are long.

  In the second drying control mode, first, the control means 39 closes the intake valve 32, switches the branch valve 41 to the downstream circulation air passage 17 side, performs the drying operation, and supplies the drying air to the inner tank 5 and downstream. The side circulation air passage 17, the upstream circulation air passage 14, and the heat pump device 25 are circulated to dry the clothes 4 in the inner tub 5. Next, when drying of the clothes 4 in the inner tub 5 is completed, the control means 39 opens the intake valve 32, switches the branch valve 41 to the exhaust air passage 40 side, and continues the drying operation. As a result, the outside air that has entered the main body 1 from the air inlet 31 flows through the heat pump device 25, is cooled and dehumidified by the heat absorber 23, is then heated by the radiator 21, and becomes dry dry air from the exhaust port 28. The clothes discharged and hung outside the main body 1 are dried. In this mode, the clothes 4 in the inner tub 5 can finish drying in the same drying time as the single drying step, and the clothes hung outside the main body 1 during this time are naturally dry and dry. After the garment 4 is dried, it is dried at once with the dry air discharged from the exhaust port 28, so that efficient drying can be performed.

  In the third drying control mode, priority is given to the drying of clothes hung outside the main body 1. First, the control means 39 opens the intake valve 32 and switches the branch valve 41 to the exhaust air passage 40 side. And dry. The outside air that has entered the main body 1 from the air inlet 31 flows through the heat pump device 25, is cooled and dehumidified by the heat absorber 23, is then heated by the radiator 21, is exhausted from the exhaust port 28 as dry dry air, The clothes hung outside the main body 1 are dried.

  Next, when drying of the clothes hung outside the main body 1 is completed, the control means 39 closes the intake valve 32, switches the branch valve 41 to the downstream circulation air passage 17 side, performs a drying operation, and dries. The working air is circulated through the inner tank 5, the downstream circulation air path 17, the upstream circulation air path 14, and the heat pump device 25 to dry the clothes 4 in the inner tank 5. In this mode, the clothes hung outside the main body 1 can finish drying in the same drying time as the single drying process. During this time, in order to promote natural drying and drying of the clothing 4 in the inner tub 5, the inner tub 5 is rotationally driven by the drive motor 6 to stir the clothing 4.

  As described above, the washing and drying machine of the present embodiment has a plurality of drying control modes in which the drying in the inner tub 5 and the hanging drying are performed at the same time, so that the drying priority order can be arbitrarily selected according to the use scene. It is easy to use.

  Furthermore, the washing and drying machine of the present embodiment has a drying process corresponding to another use scene. It is for when you want to do the next wash during hanging drying. This is a control mode in which the drying time is prolonged when hanging and drying in large quantities, but the washing and drying are performed simultaneously without stopping the drying operation.

  In this washing / drying simultaneous control mode, the control means 39 opens the intake valve 32 and switches the branch valve 41 to the exhaust air passage 40 side to perform the drying operation, and at the same time, the washing process operation and the dehydration process operation. The operation of the drying process can be continued in an arbitrary drying mode after the dehydration process is completed.

  As described above, by having a plurality of drying control modes and a simultaneous washing / drying control mode, it is possible to realize a laundry dryer that is very easy to use according to various usage situations.
