Therefore, the apparatus main body 10 stops at a position where it is lowered with respect to the sub suction duct joint 50. Thus, a gap S3 is formed between the main body flange portion 14 of the apparatus main body 10 on the side of the sub suction duct joint 50 and the ceiling 100a.

  Further, on the exhaust duct joint 40 side, the exhaust duct joint 40 is not fixed to the ceiling 100a, and there is a slight gap between the apparatus main body 10 and the ceiling 100a, so the apparatus main body 10 tilts downward. Go down. At this time, since the lower surface of the exhaust duct 12 is caught on the back surface of the ceiling 100a, the apparatus main body 10 stops at a predetermined tilted position.

  Further, since the exhaust duct joint 40 does not have a temporary fixing function, the apparatus main body 10 slightly slides and falls downward with respect to the exhaust duct joint 40 due to its own weight. The main body 10 stops at a predetermined position of the exhaust duct joint 40. As a result, a gap S4 is also formed between the main body flange portion 14 on the exhaust duct joint 40 side of the apparatus main body 10 and the ceiling 100a. The clearance S4 on the exhaust duct joint 40 side is wider than the clearance S3 on the sub suction duct joint 50 side.

  Thereby, the installer can know that the apparatus main body 10 is not being fixed to the ceiling 100a by seeing these clearance gaps S3 and S4. Further, when the front panel 11 is pressed against the apparatus main body 10, the gaps S3 and S4 can be grasped, so that it is possible to know that the apparatus main body 10 is not fixed to the ceiling 100a.

[When using a single room type bathroom ventilation drying and heating system]
In the above-described embodiment, the bathroom ventilation drying and heating apparatus 1A that performs ventilation and the like of a plurality of rooms such as the bathroom 100 and the washroom 102 is used. However, the bathroom ventilation drying and heating that performs ventilation and the like of only one room of the bathroom 100 is used. The temporary fixing function according to the present embodiment can also be applied to the device 1B.

  Here, since the one-room type bathroom ventilation drying / heating apparatus 1B ventilates only the bathroom 100, the auxiliary suction duct joint 50 and the like for ventilating the washroom 102 and the like are not provided. Therefore, the temporary fixing function described above is provided only on one side of the apparatus main body 10 on the exhaust duct joint 40 side. As described above, the exhaust duct joint 40 is slidably attached to a guide portion (not shown) provided on the side surface 10a of the apparatus body 10, and is attached to the ceiling 100a on the bathroom 100 side by a fastening member such as a screw.

  FIG. 15 shows a case where a one-room type bathroom ventilation drying / heating apparatus 1B is used, and the apparatus body 10 is not fixed to the ceiling 100a after the apparatus body 10 is temporarily fixed to the exhaust duct joint 40. The state of the main body 10 is shown. As shown in FIG. 15, when the apparatus main body 10 is temporarily fixed to the exhaust duct joint 40 and then released, on the exhaust duct joint 40 side, the apparatus main body 10 is formed by a long hole provided in the protruding piece of the flange portion 53. Slide downward with respect to the exhaust duct joint 40. Thereby, a gap S5 is formed between the main body flange portion 14 of the apparatus main body 10 and the ceiling 100a.

  Further, even on the side surface 10b opposite to the side surface 10a of the apparatus main body 10 to which the exhaust duct joint 40 is connected, the apparatus main body 10 tilts downward due to a gap provided between the apparatus main body 10 and the ceiling 100a. When the side surface 10b of the apparatus main body 10 hits the opening edge of the ceiling 100a, it stops at a predetermined position. Thereby, a gap S6 is also formed between the main body flange portion 14 of the apparatus main body 10 and the ceiling 100a. The clearance S6 on the exhaust duct joint 40 side is wider than the clearance S5 on the sub suction duct joint 50 side.

  Thereby, the installer can know that the apparatus main body 10 is not being fixed to the ceiling 100a by seeing these clearance gaps S5 and S6. Further, when the front panel 11 is pressed against the apparatus main body 10, the gaps S5 and S6 can be grasped, so that it can be known that the apparatus main body 10 is not fixed to the ceiling 100a.

  As described above, according to the present embodiment, the protruding piece 54 having the hole 55 is provided in the flange portion 53 of the auxiliary suction duct joint 50 necessary for construction, and the temporary fixing member is provided in the main body flange portion 14 of the apparatus main body 10.
