(Embodiment 1)
The structure of the ventilation drying apparatus concerning Embodiment 1 of this invention is shown in FIG.1 and FIG.2.

  FIG. 1 shows a schematic configuration of the ventilation drying apparatus. As shown in FIG. 1, the outdoor unit 101 promotes the heat absorption of the refrigerant by forcibly supplying the external air to the heat absorber 103, the compressor 102 that compresses the refrigerant, the heat absorber 103 that absorbs heat from the outside air. An outdoor blower 104 and an expansion mechanism 001 that expands the refrigerant by decompressing it are provided. The indoor unit 105 also includes a radiator 002 in which the refrigerant radiates heat to the room air, and an indoor fan 108 that forcibly supplies the room air to the radiator 002 and promotes heat dissipation of the refrigerant. The outdoor unit 101 and the indoor unit 105 are connected by a first refrigerant pipe 109 and a second refrigerant pipe 110, and the refrigerant is a compressor 102, a first refrigerant pipe 109, a radiator, a second refrigerant pipe 110, an expansion mechanism 001, A refrigerant circuit 111 that circulates in the order of the heat absorber 103 is configured. Thereby, the refrigerant | coolant which absorbed heat from external air can thermally radiate to indoor air, and can heat a room. In addition, since the compressor 102 that generates generally large noise and vibration and the expansion mechanism 001 that generally generates large noise are arranged in the outdoor unit 101, the room can be kept quiet. Further, a ventilation device 112 is connected to the outdoor side wall surface of the wall body 113 separating the inside and outside of the room, and a ventilation air passage 116 communicating with the outside of the room is connected to exhaust a part of the indoor air to the outside. As a result, the object to be dried 003 is placed in the room, and the indoor circuit is heated by the refrigerant circuit 111 described above to reduce the water vapor partial pressure of the room air, thereby transferring moisture from the object to be dried 003 to the room air. If a part of room air is exhausted outside by the ventilator 112 while promoting, drying of the to-be-dried object 003 can be promoted. In order to penetrate the wall body 113 through the above-described ventilation air passage 116 and the refrigerant circuit passage 114 through which the first refrigerant pipe 109 and the second refrigerant pipe 110 are passed, a single unit that communicates with the wall body 113 indoors and outdoors. A hole 004 is opened.

  FIG. 2 shows a configuration in the vicinity of a single hole that communicates indoors and outdoors. As shown in FIG. 2A, the indoor mounting plate 005 for fixing the indoor unit 105 to the wall body 113 includes a ventilation air passage indoor side opening 006 for connecting the ventilation air passage 116, and a first refrigerant pipe. 109 and the second refrigerant pipe 110 are provided with a refrigerant circuit passage indoor side opening 007. A single hole 004 that communicates indoors and outdoors with a size that can simultaneously include the ventilation air passage indoor side opening 006 and the refrigerant circuit passage indoor side opening 007 is formed in the wall body 113, and the indoors and outdoors communicate with each other. If the indoor mounting plate 005 is fixed to the indoor side opening 008 of this hole, all of the ventilation air passage 116, the first refrigerant pipe 109, and the second refrigerant pipe 110 are connected even if there is a single hole communicating with the outside of the room. The wall body 113 can be penetrated. Further, by fixing the indoor unit 105 to the wall surface with the above-described indoor mounting plate 005, the indoor side opening 008 of a single hole that communicates indoors and outdoors can be concealed.

  It should be noted that the indoor mounting plate 005 has a ventilation air passage indoor side opening 006 and a refrigerant circuit passage indoor side opening 007 of about 180 mm square which is a general size of a natural ventilation port found in a general conventional construction bathroom or the like. If it prepares so that it can be included by this square hole, it will be able to install using the existing square hole, and also can reduce construction man-hours.

  In this embodiment, the relative positional relationship between the refrigerant circuit passage and the ventilation air passage 116 is determined by using an indoor attachment plate 005 for fixing the indoor unit 105 to the wall body 113, and the ventilation air passage on the indoor attachment plate 005. The indoor side opening 006 and the refrigerant circuit passage indoor side opening 007 are defined to be close to each other, and the ventilation device 116 is fixed to the outdoor side wall surface of the wall body 113. The indoor mounting plate 005 is not essential as long as it is configured not to be built in 105 so that the penetration position of the ventilation air passage 116 can be set in the vicinity of the refrigerant pipe protruding from the indoor unit 105.

  Further, as shown in FIG. 2 (b), the single hole 004 that communicates indoors and outdoors is sufficiently thicker than the combined thickness of the first refrigerant pipe 109 and the second refrigerant pipe 110, and is relatively constructed than the square hole. If an easy round hole is formed, and the ventilation air passage 116 having almost the same size as the round hole is passed through the round hole, and the first refrigerant pipe 109 and the second refrigerant pipe 110 are passed through the ventilation air passage 116, the ventilation air passage 116 is obtained. Will also serve as a refrigerant circuit passage.

(Embodiment 2)
FIG. 3 shows the configuration in the vicinity of the pipe connection portion of the ventilation drying apparatus according to the second embodiment of the present invention. As shown in FIG. 3, the first refrigerant pipe 109 and the second refrigerant pipe 110 pass through the ventilation air passage 116. Moreover, the 1st refrigerant | coolant piping 109 and the 2nd refrigerant | coolant piping 110 have detachable piping connection part 009, such as a flare connection, for example. Compared with the other part of the 1st refrigerant | coolant piping 109 or the 2nd refrigerant | coolant piping 110, the above-mentioned piping connection part 009 has a large cross-sectional area orthogonal to a refrigerant | coolant distribution direction. Further, the first auxiliary refrigerant pipe 010 and the second auxiliary refrigerant pipe 011 extending from the indoor unit 105 to the pipe connection part 009 are configured to be longer than the thickness of the wall body 113 that separates the interior and the exterior. As a result, the pipe connection part 009 is always arranged on the outdoor side, and the resistance of the ventilation air passage 116 is not increased by the pipe connection part 009 having a relatively large cross-sectional area perpendicular to the refrigerant flow direction. In addition, since the pipe connection portion 009 is arranged outside, the pipe connection work can be performed after the indoor unit 105 is fixed, and the construction can be facilitated. In the present embodiment, the pipe connection part 009 is a flare connection, but it may be detachable, and may be a flange connection or the like.

(Embodiment 3)
FIG. 4 shows the configuration in the vicinity of the refrigerant pipe passing through the ventilation air passage of the ventilation drying apparatus according to the third embodiment of the present invention. As shown in FIG. 4, the 1st refrigerant | coolant piping 109 is covered with the heat insulating material 012 for preventing the heat exchange with air. The second refrigerant pipe 110 may not be covered with the heat insulating material 012. However, when the refrigerant pipe generally used in the room air conditioner is used, the first refrigerant pipe 109 and the second refrigerant pipe 110 are used. Both are generally covered with a heat insulating material 012. The heat insulating material 012 covering the refrigerant pipe in the ventilation air passage 116 is thinner than the heat insulating material 012 in other portions. Thereby, while reducing the heat loss caused by the refrigerant pipe radiating heat to the surrounding air, the increase in ventilation resistance of the ventilation air passage 116 can also be reduced, and the ventilation air passage 116 also serves as the refrigerant circuit passage. Can be made easier.

(Embodiment 4)
FIG. 5 shows the configuration in the vicinity of the refrigerant pipe passing through the ventilation air passage of the ventilation drying apparatus according to the fourth embodiment of the present invention.

  FIG. 5 shows a schematic configuration of the ventilation drying apparatus. As shown in FIG. 5, the expansion mechanism 001 is a capillary tube and is disposed in the ventilation air passage 116. Since the capillary tube has a smaller cross-sectional area perpendicular to the refrigerant flow direction than other parts of the refrigerant circuit, the ventilation air passage 116 also serves as the refrigerant circuit passage while suppressing an increase in ventilation resistance of the ventilation air passage 116. Construction can be facilitated.

(Embodiment 5)
The structure of the ventilation drying apparatus concerning Embodiment 5 of this invention is shown in FIG.6 and FIG.7.

  FIG. 6 shows a schematic configuration of the ventilation drying apparatus. As shown in FIG. 6, the outdoor unit 101 includes a refrigerant circuit 111, a first refrigerant flow including a compressor 102, a first refrigerant pipe 109, a radiator 002, a second refrigerant pipe 110, an expansion mechanism 001, and a heat absorber 103. A four-way valve 013 that switches to the second refrigerant flow order of the compressor 102, the heat absorber 103, the expansion mechanism 001, the second refrigerant pipe 110, the radiator 002, and the first refrigerant pipe 109 is provided. When the room is heated, the operation is continued as the first refrigerant circulation order. At this time, if the outdoor temperature is low, frost adheres to the heat absorber 103. If the first refrigerant flow sequence is continued as it is, frost adhering to the heat absorber 103 grows and hinders heat exchange between the heat absorber 103 and the outside air. Therefore, the four-way valve 013 switches the refrigerant flow to the second refrigerant circulation sequence by some trigger, causes the high-temperature and high-pressure refrigerant compressed by the compressor 102 to flow through the heat absorber 103, and dissolves frost. At this time, the heat absorber 103 temporarily functions as a heat radiator, and the heat radiator 002 temporarily functions as a heat absorber. Therefore, the temperature of the radiator 002 is lowered and condensation occurs in the radiator 002. The indoor unit 105 includes a water tray 014 for receiving the condensed water.

  FIG. 7 shows a schematic configuration near the water tray. As shown in FIG. 7, the water tray 014 includes a drain hole 015 at the bottom thereof, and a water conduit 016 is connected to the drain hole. The water conduit 016 passes through the ventilation air passage 116 and protrudes outside the room, but the lowermost part of the water receiving tray 014 is vertically higher than the lowermost part of the indoor side opening 008 of the single hole that communicates indoors and outdoors. The indoor unit 105 is fixed to. As a result, the water conduit 016 naturally has a downward slope toward the outside, and the dew condensation water received by the water tray 014 is discharged to the outside through the water conduit 016 by its own weight.

  The ventilating and drying apparatus according to the present invention provides a ventilating and drying apparatus that can be easily installed by providing the ventilation air passage and the refrigerant circuit passage in a single hole that communicates indoors and outdoors. This is useful when installed in a bathroom of a house or the like to heat or dry.
