As can be seen from the fact that the connection port 50a is larger than the pipe passage 54, the connection port 50a of the bent cover 58 cannot be inserted into the pipe passage 54 as in the conventional example, and the rib 56 With this, it is positioned on the surface of the mounting board 55. As shown in FIG. 6A, the rib 56 of the mounting board 55 is
Is provided so as to surround a region including the opening 54a of the exhaust passage 53 and excluding the opening 53a of the exhaust passage 53. The bent cover 58 can be attached to the mounting board 55 so that the connection port 50a is sandwiched between the ribs 56.
The bent cover 58 can be attached in three directions so that the exhaust passage 53 does not block the exhaust passage 53. When the bent cover 58 is mounted on the mounting board 55 in these three directions, screw holes 57 are provided at positions opposite to the mounting holes 50c of the bent cover 58, and the screw holes 57 are provided through the mounting holes 50c of the bent cover 58. The bent cover 58 can be fixed to the mounting board 55 by fixing the set screw to the screw hole 57. In the illustrated example, the connection port 50b is also positioned by the rib 56. However, only the connection port 50a may be positioned by the rib 56.

FIGS. 8, 9 and 10 show the drawing direction of the pipe 60 and the mounting angle of the bent cover 58. In each case, the opening 54a of the pipe passage 54 is covered by the connection port 50a of the bent cover 58. Have been done. FIG. 8 shows the mounting direction of the bent cover 58 corresponding to the pipe 60 drawn leftward. This is effective when an obstacle such as a window or an eave exists below the through hole 44. If it is necessary to pipe downward, the pipe 60 is disposed to the heat source device by exiting the pipe 60 to the left and bending the pipe 60 downward to avoid obstacles. FIG.
Shows a state in which the bent cover 58 is attached so as to correspond to the pipe 60 drawn downward. This is a normal construction method.

FIG. 10 shows a construction state when the pipe 60 is to be pulled out to the right. When the pipe 60 is directly pulled out to the right, the exhaust passage 53 is blocked. Therefore, the pipe 60 is drawn up once and then bent rightward above the outdoor hood 63. This is because when the pipe 60 is to be pulled out to the right, there is an obstacle on the left side of the through-hole 44, and the pipe cannot be laid down from the left because it is detoured from the left, and the pipe 60 is laid down from the right side. In this case, the construction is effective.

After the pipe 60 is thus constructed and the bent cover 58 is mounted on the mounting board 55, an outdoor hood 63 for preventing rainwater from entering is mounted on the mounting board 55 so as to cover the bent cover 58. The outdoor hood 63 has a structure as shown in FIG. 11, and has a knockout portion 64 formed on the upper surface and the left side surface so as to have a thin wall around or around the entirety. In the case where the pipe is provided downward as shown in FIG. 9, the pipe is fixed to the mounting board 55 as it is so that only the lower surface is opened. On the other hand, when the pipe 60 is pulled out to the left as shown in FIG. 8, the left knockout portion 64 is cut with a cutter or a cutter to form an opening 64a, and the bent cover 58 or the pipe Pass through the duct 61. Similarly,
When pulling out the pipe 60 as shown in FIG. 10, the knockout portion 64 on the upper surface is cut, and the bent cover 58 or the pipe duct 61 is passed through the opening 64a.

As described above, the bathroom heating / drying apparatus 1 of the present invention.
Then, since the direction in which the pipe is pulled out from the through hole 44 can be changed according to the environment of the installation location, there are few restrictions on the construction, and it can be easily applied to a house where the installation work was conventionally difficult. Can be installed at a high speed, which increases flexibility.

Further, since the connecting pipe 22 passing through the through hole 44 of the bathroom wall 41 is shortened and both ends thereof can be connected to the pipes 3 and 60 near the through hole 44, it can be used indoors or outdoors. The connecting pipe 22 can be passed through the through hole 44, and the connecting work of the connecting pipe 22 can be performed on either the indoor side or the outdoor side, and the order can be arbitrarily selected. Can be adjusted, and the labor for moving indoors and outdoors can be reduced, and the workability can be improved.
