Description

  The present invention relates to a drying apparatus that dries clothes and the like by using a heat exchange action of a heat pump unit.

  In recent years, a laundry dryer is known as an example of this type of drying apparatus. And as a drying means of the washing and drying machine, a drying method using heat pump technology has been proposed and attracted attention in place of the conventional electric heater. Drying with a heat pump is performed by dehumidifying high-humidity air circulating from the washing tub with a heat absorber of the heat pump device, and then circulating it again into the tub as high-temperature, low-humidity air with a radiator to dry clothes and the like. It is something to be made. This method has higher energy efficiency, lower temperature, and lower humidity air than conventional electric heaters, and therefore reduces wrinkles of clothing and damage to the fabric after drying. Conventionally, this type of washing and drying machine is integrated with a heat exchanger and a compressor of a heat pump device mounted on a base plate (see, for example, Patent Document 1).

  FIG. 7 shows a conventional washing and drying machine described in Patent Document 1. As shown in FIG. 7, the conventional washing and drying machine has a water tank 102 disposed in an outer box 101, and a heat exchange air passage 103 incorporating a blower 108 is provided in the lower part thereof. A heat absorber 104 and a radiator 105 are arranged in the heat exchange air passage 103, and the heat exchange air passage 103 and the compressor 106 are mounted on a metal base plate 107.

  In the washing and drying machine configured as described above, all the parts forming the refrigeration cycle are stored in the outer box 101, and the heat exchange air passage 103 is discharged from the water tank 102 by driving the blower 108. The wind is cooled by the heat absorber 104 and dehumidified. The dehumidified low-humidity drying air is heated by the radiator 105 and supplied from the heat exchange air passage 103 to the water tank 102. In the heat exchange air passage 103, the compressor 106 is mounted on the base plate 107, and the heat absorber 104 and the heat radiator 105 are installed in the heat exchange air passage 103, and a pipe through which the refrigerant flows through the compressor 106. A refrigeration cycle is formed by connecting the roads.

  Further, a base plate 107 corresponding to the base is fixed in the outer box 101. In forming the refrigeration cycle, the configuration in which the heat exchanger and the compressor 106 are directly mounted in the outer box 101 performs the brazing operation and the vacuuming operation in an environment where necessary parts are assembled as a washing machine. As a result, the assembly work is inefficient.

  For this reason, it is set as the structure which can handle several elements required in order to comprise a refrigerating cycle independently. Therefore, since it can be assembled in a specialized assembling process for handling the refrigeration cycle, not only the assembly is facilitated, but also the equipment and the like can be shared with parts assembly of other products. As a result, capital investment and the like are reduced, and it is possible to manufacture a cheap and good product. In addition, since the test and the like can be performed reliably, the reliability of the product is increased.

However, in the above conventional configuration, the compressor, the radiator, the throttle means (not shown), and the heat absorber are connected by a pipe line such as a copper tube, and the wind flows through the heat absorber and the radiator. However, in order to integrate the heat pump device and the heat exchange air passage, a base plate with the same area as the bottom of the washing machine is required. When assembling the machine, it is necessary to assemble the outer box and the water tank in order. Also, when a failure occurs in the refrigeration cycle section, it is necessary to disassemble the entire washing machine, and even if it becomes possible to take out the refrigeration cycle section by devising the take-out direction etc. However, there is a problem that the disassembly is complicated, the number of parts is large, and the configuration is complicated.

  An object of the present invention is to remove the rotating drum when the back plate and the side plate are removed, so that the rotating drum can be removed while maintaining the framework, so that the restoration can be easily performed and the workability such as maintenance can be improved. is there.
