According to a construction method in which an exhaust path is passed through the first opening and its through hole, and a pipe is passed through the second opening and its through hole, the bathroom wall is provided with two exhaust holes.
Since it is necessary to make two through holes, the labor for drilling the bathroom wall increases, but the drilling tool can be small, so the drilling of the bathroom wall becomes easy, and Exhaust passages can be separately constructed, which simplifies piping work. Since the bathroom heating and drying apparatus of the present invention can select any construction method, it depends on the construction method that is easy for the constructor, or according to the drilling tool owned by the constructor, or in the state of the bathroom wall. Arbitrary construction methods can be selected accordingly.

According to a third aspect of the present invention, in the bathroom heating / drying apparatus according to the first aspect, a joint pipe is detachably connected to an end of a pipe provided in the main body case, and is connected to the heat exchanger. The pipe for circulating the heat medium can be extended between the vicinity of the first opening and the vicinity of the second opening by a joint pipe.

In this embodiment, since the pipe in the main body case can be extended by the joint pipe, the end of the pipe in the main body case is located near the first opening according to the two construction states. Can also be located in the vicinity of the second opening, thereby facilitating the connection work between the pipe passed through the bathroom wall and the pipe in the main body case.

Circulates a high-temperature heat medium to the pipe 13 of the heat exchanger 14, and drives the hot-air blowing fan 15 to discharge relatively low-temperature hot air from the hot-air outlet 19 of the bathroom heating / drying device 11. The bathroom can be heated. Also,
By discharging high-temperature warm air from the warm air outlet 19 of the bathroom heating / drying device 11 while the clothes 52 are suspended in the bathroom, the clothes can be dried, and the bathroom can be converted to a clothes drying room. Becomes possible. Furthermore, the ventilation blower 24
By driving the air conditioner, the air containing moisture in the bathroom can be discharged to the outside to ventilate the bathroom.

(First Construction Method) Next, a construction method of the bathroom heating / drying apparatus 11 will be described with reference to FIG. Bathroom wall 5
The attachment to 1 can be easily performed by using the support plate 44. That is, after the mounting position of the bathroom heating / drying device 11 is determined, only the support plate 44 is screwed to the bathroom wall 51 according to the mounting position. Next, the opening position of the bathroom wall 51 is determined using a pattern or the like, and the opening position is relatively large (for example, the opening 3 of the main body case 12).
(The diameter is set to 120 mm in accordance with Step 2). Alternatively, when the bathroom wall 51 has an existing ventilation port, the existing ventilation port is used as the through hole 54, and the support plate 44 is attached to the bathroom wall 51 in accordance with the through hole 54.

Next, a through hole 54 opened in the bathroom wall 51 is provided.
A pipe 55 made of vinyl chloride (PVC pipe) is fitted to the inner periphery of the container, and an indoor side cap 56 as shown in FIG. The indoor side cap 56 is formed in a substantially cylindrical shape from a soft material such as rubber or soft vinyl chloride resin, and has a flange 57 for closing a gap between the indoor side cap 56 and the through hole 54.
Is provided at one end, and a fitting portion 58 for inserting the end of the PVC pipe 55 without any gap is provided on the inner periphery.

Thereafter, the bathroom heating / drying device 11 is attached to the bathroom wall 51 so as to be hooked on the support plate 44. At this time, the duct 27 protruding from the back surface of the bathroom heating / drying device 11 is inserted into the indoor side cap 56 and located above the through hole 54 and the PVC pipe 55. The flange 57 of the indoor side cap 56 is pressed by the main body case 12 (the edge of the opening 32). Next, the exhaust pipe 59 is inserted into the PVC pipe 55 from the outdoor side, the end of the exhaust pipe 59 is connected to the duct 27 of the ventilation blower 24, and the exhaust pipe 59 is positioned above the through hole 54 and the PVC pipe 55. Let it.

On the other hand, an outdoor side cap 60 as shown in FIG. 10 is attached to the end of the through hole 54 from the outdoor side. The outdoor side cap 60 is formed of a soft material such as rubber or soft vinyl chloride resin, and a gap is formed between the outdoor side cap 60 and the through-hole 54 around the protrusion 61 inserted into the through-hole 54 from the outdoor side. Is provided. An end of a PVC pipe 55 is inserted into and connected to the inner periphery of the cylindrical projection 61. Further, an exhaust port 63 is opened in the upper part of the protrusion 61, and the exhaust port 6
3, a connecting portion 64 for inserting an end of the exhaust pipe 59 is projected, and a pipe through hole 65 is provided below the connecting portion 64.
Is open.

Thereafter, the front cover 18 of the bathroom heating / drying device 11 is removed to expose the joint pipe 36. And
A heat medium supply pipe 66 is guided from the heat source device along the outer wall of the house or the like, and the space 67 outside the exhaust pipe 59 is inserted through the pipe through hole 65.
Through the pipe 66 and below the ventilation blower 24 to connect the pipe 66 to the joint pipe 36. The wiring (signal line) 31 of the controller 43 is also connected to the heat source device through the through hole 54 (space 67) and the piping through hole 65 together with the piping 66. When the operation is completed, the front cover 18 is attached to the main body case 12 again.

Finally, the pipe passage hole 65 through which the pipe 66 and the wiring 31 pass is appropriately covered with a cover 68, and the pipe 66 and the wiring 31 exposed on the outer wall are covered with a decorative molding 69. Further, an outdoor hood 70 is attached to an outlet portion of the exhaust pipe 59.

As described above, the bathroom heating / drying apparatus 11 of the present invention is used.
Has an opening 32 at the back of the main body case 12 through which the duct 27 and the pipe 66 of the ventilation blower 24 can pass. Therefore, one through hole 54 corresponding to the opening 32 is formed in the bathroom wall 51 as well. With the opening, the exhaust pipe 59 and the pipe 66 of the ventilation blower 24 can be simultaneously disposed in one through hole 54. Therefore, as in the conventional case, the through hole and the pipe 6 for passing the exhaust pipe 59 of the ventilation blower 24 are provided.
There is no need to separately provide a through hole for passing 6 through the bathroom wall 51, and the installation work of the bathroom heating / drying device 11 can be simplified. In addition, since the number of through holes 54 formed in the bathroom wall 51 is reduced, restrictions on the opening of the through holes 54 are reduced, and construction is facilitated.

In addition, despite the fact that the wall openings (through holes 54) for the exhaust and the wiring are shared, the exhaust passage formed by the duct 27 and the exhaust tube 59 has a space 67 through which the pipe 66 passes.
The structure is independent from the above, and it is possible to prevent the exhaust gas from leaking on the way.

In the bathroom heating / drying apparatus 11, an opening 32 is formed in the upper part of the main body case 12, a ventilation blower 24 is installed in a horizontally long form above the opening 32, and a controller 43 is arranged below the ventilation blower 24. Since the opening 32 is exposed between the ventilation blower 24 and the controller 43, when an existing ventilation opening is provided in the bathroom wall 51,
The bathroom heating / drying device 11 can be attached to the bathroom wall 51 so that the opening 32 matches the ventilation port, and the existing ventilation port can be used as the through hole 54. Further, according to such an arrangement, not only the pipe 66 but also the wiring 31 of the controller 43 can be passed through the pipe through hole 65. Therefore, in this case, the bathroom wall 5
It is not necessary to perform opening work on the bathroom heating and drying equipment 1
(1) Installation work can be further simplified. Further, according to such an arrangement, the heat exchanger 14, the ventilation blower 24, the controller 43, and the like can be arranged collectively in a compact manner. Further, since the controller 43 is disposed at a lower position, maintenance and adjustment when the controller 43 fails can be performed easily, and operations such as setting and changing special switches inside the controller 43 also become easier.

(Second Construction Method) In the bathroom heating / drying apparatus 11 of the present invention, the bathroom wall 51 is made to correspond to the opening 32.
A through hole 54 is opened in the bathroom wall 5 corresponding to the opening 35.
1, a through hole 74 may be opened, a pipe 66 and a wiring 31 may be provided in the opening 35 and the corresponding through hole 74, and an exhaust pipe 59 may be provided in the opening 32 and the corresponding through hole 54. If only the exhaust pipe 59 is made to pass through the opening 32 in this manner, the through hole 54 opened in the bathroom wall 51 corresponding to the opening 32 may be small, and the wall opening work may be performed using a small drilling tool. It can be done easily. Further, since only the exhaust pipe 59 needs to be passed through the opening 32 and the through hole 54, piping work can be easily performed. FIG. 11 shows such a construction state. However, in FIG. 11, the bathroom wall 51 and the main body case 12 are cross-sectioned in a stepped manner.

When such a construction method is adopted, two through holes 5 are formed in the bathroom wall 51 so as to correspond to the openings 32 and 35 formed in the main body case 12 of the bathroom heating / drying device 11.
4, 74 are opened. However, the through hole 54 is formed in the duct 27
And the exhaust pipe 59 need only pass through, so that it does not need to be large as in the construction state of FIG.

As the caps used on the indoor side, two kinds of indoor side caps 56 and 71 as shown in FIG. 12 are prepared. One indoor side cap 56 has already been described, and the outer diameter of the flange 57 is larger than the opening 32. The other indoor-side cap 71 is smaller than the indoor-side cap 56, and has a cylindrical portion 72 and a flange 7.
3, and the outer diameter of the flange 73 is larger than the opening 35.

When a through-hole 54 that allows the exhaust pipe 59 and the pipe 66 to pass simultaneously is opened in the bathroom wall 51 (FIG. 8),
On the indoor side, only the indoor side cap 56 is used as described above, and the indoor side cap 71 is not used. On the other hand, in a construction state in which the exhaust pipe 59 and the pipe 66 are passed through the separate through holes 54 and 74, both the indoor side caps 56 and 71 are used, and the indoor side cap 56 is fitted into the through hole 54, and The inner cap 71 is fitted into the through hole 74. However, since the indoor side cap 56 is large because it is adjusted to the construction state as shown in FIG. 8, when it is used in the construction state as shown in FIG. 11, as shown in FIG. A part of 56 is cut, reduced as shown in FIG. 13B, and inserted into the through hole 54. Thus, when the indoor side cap 56 is cut to reduce the diameter, the indoor side cap 56
Since the flange 57 of the ventilator is not held down by the edge of the opening 32 and the indoor cap 56 may rise, the projection 34 is provided on the mounting plate 29 of the ventilation blower 24, and the flange 57 is pressed by the projection 34, and the indoor cap 56 is pressed. To prevent floating.

The exhaust pipe 59 inserted into the through hole 54
Is connected to the duct 27, and in the through hole 74 (the through hole 74
A PVC pipe may be inserted in the inner periphery of the pipe 66), the pipe 66 and the wiring 31.
, Individual outdoor side caps 75 and 76 are fitted to the outdoor side of each through hole 54 and 74.

In the bathroom heating / drying apparatus 11 of the present invention, the exhaust pipe 59 and the pipe 66 are provided in the opening 32 and the through hole 54 thereof.
In the construction method of passing through, the hole made in the bathroom wall 51 may be only one through hole 54, and the labor of the drilling work is reduced,
Since the through hole 54 is large, a large drilling tool is required, making drilling work difficult and piping work complicated. On the other hand, the exhaust pipe 59 passes through the opening 32 and the through hole 54, and the pipe 66 passes through the opening 35 and the through hole 74.
In the construction method of passing through the wiring 31, it is necessary to make two through holes 54 and 74 in the bathroom wall 51, so that the labor for drilling the bathroom wall 51 increases, but a small drilling tool should be used. Therefore, the work of perforating the bathroom wall 51 becomes easy, and the piping 66 and the exhaust pipe 59 can be separately constructed, so that the construction is also simplified. Since the bathroom heating and drying apparatus 11 of the present invention can select any construction method,
An arbitrary construction method can be selected according to an easy construction method of a constructor, a drilling tool owned by the constructor, or according to a state of a bathroom wall.

In the above embodiment, the wall-mounted bathroom heating / drying device has been described. However, the present invention is not limited to the wall-mounted type and may be a ceiling-mounted type. The present invention can also be applied to a ceiling-mounted bathroom heating / drying apparatus in a case where a through hole is made in the bathroom wall behind the ceiling through the space above the ceiling and an exhaust pipe or piping is passed.
