Among the four line segments that make up the above trapezoid, the line segment perpendicular to the above two line segments represents the first surface 31. The remaining one hypotenuse among the four line segments represents the second surface 32. The second surface 32 has an inclination and forms an upward slope toward the side opposite to the side of the flange 15.

FIG. 9 is a diagram showing a state where the bathroom dryer 1 shown in FIG. 1 is fixed to the frame material 16. FIG. 9 shows the cross section of the frame material 16 and the planar configuration of the bathroom dryer 1. In the installed state, the lower surface 23 is in contact with the lower edge 17a of the opening 17, whereby the frame material 16 bears the weight of the bathroom dryer 1. In the installed state shown in FIG. 9, the surface 16a and the lower surface 23 are perpendicular to each other. The first surface 31 is parallel to the surface 16a.

The bathroom dryer 1 is fixed to the frame 16 after passing the sheet metal frame 8 from the bathroom to the outside through the opening 17. In the bathroom dryer 1, the sheet metal frame 8 is placed on the edge 17a, and the lower surface 23 is slid in the edge 17a to pass through the opening 17. In a state where the lower surface 23 is in contact with the edge 17a, a slight gap is formed between the upper edge 17b of the opening 17 and the upper surface 36 of the sheet metal frame 8.

The lower surface 23 is slid in the rim 17a. When the protrusion 27 reaches the rim 17a, the second surface 32 is slid in the rim 17a, thereby causing the protrusion 27 to go over the rim 17a. Since the second surface 32 is inclined, the protrusion 27 can easily go over the edge 17a.

After the protrusion 27 passes over the edge 17 a, the portion between the protrusion 27 and the flange 15 in the lower surface 23 slides in the edge 17 a, so that the flange 15 reaches the frame material 16. In a state where the flange 15 is in contact with the frame material 16, the flange 15 is fixed to the frame material 16 to fix the bathroom dryer 1 to the frame material 16.

Before the work for fixing the flange 15 to the frame material 16 is started, the bathroom dryer 1 is in an unstable state against external forces. Since the external force is unstable, the bathroom dryer 1 will return to the bathroom side due to the wind outside. In this case, the bathroom dryer 1 loads the sheet metal frame 8 on the edge 17a by the weight of the bathroom dryer 1, and receives wind force and moves to the bathroom side.

FIG. 10 is a diagram showing a state when the bathroom dryer 1 shown in FIG. 1 is fixed to the frame 16 before the bathroom dryer 1 is moved to the bathroom side. When the bathroom dryer 1 moves to the bathroom side, the lower surface 23 slides in the edge 17a, and the first surface 31 of the protrusion 27 reaches the edge 17a. Since the first surface 31 is perpendicular to the lower surface 23, the protrusion 27 is prevented from passing over the edge 17a. Because the protrusion 27 cannot go over the edge 17a, the movement of the bathroom dryer 1 is stopped when the first surface 31 is in contact with the edge 17a. This prevents the bathroom dryer 1 from falling down before the bathroom dryer 1 is fixed.

In a state where the first surface 31 is in contact with the edge 17a, the bathroom dryer 1 receives wind from outside, and the entire bathroom dryer 1 rotates with the contact point of the first surface 31 and the edge 17a as a fulcrum. Fig. 10 shows a state where the bathroom dryer 1 is inclined so that the bathroom side faces downward. In the above state, because the first surface 31 is in contact with the edge 17a, and the upper surface 36 is in contact with the edge 17b, the bathroom dryer 1 is prevented from rotating further. Thereby, the bathroom dryer 1 is prevented from falling due to rotation. Furthermore, when the bathroom dryer 1 is inclined so that the bathroom side faces upward, the bathroom dryer 1 moves to the outside of the house, thereby preventing the bathroom dryer 1 from falling.

In the first embodiment, the so-called first surface 31 is perpendicular to the lower surface 23, in addition to the case where the first surface 31 is completely perpendicular to the lower surface 23, it also includes the perpendicularity of the first surface 31 to a surface that is completely perpendicular to the lower surface 23. The surface is slightly inclined. The so-called slightly inclined case is that the first surface 31 is a surface close to the vertical surface, which is to prevent protrusions when the bathroom dryer 1 moves to the bathroom side with the sheet metal frame 8 placed on the edge 17a. The extent to which the portion 27 crosses the edge 17a.

In the first embodiment, the so-called first surface 31 is parallel to the surface 16a, in addition to the case where the first surface 31 and the surface 16a are completely parallel, it also includes the first surface 31 with respect to the surface which is completely parallel to the surface 16a. The parallel mask is slightly tilted. The so-called slightly inclined case is that the first surface 31 is a surface close to the parallel surface, which is to prevent protrusions when the bathroom dryer 1 moves to the bathroom side with the sheet metal frame 8 placed on the edge 17a. The extent to which the portion 27 crosses the edge 17a.

Fig. 11 is an exploded view of the sheet metal frame 8 shown in Fig. 6. The sheet metal frame 8 has a lower surface 23, an upper surface 36, and three side surfaces 37, 38, and 39. The side surface 37 is a surface parallel to the surface 16a in the installed state. The side surface 38 and the side surface 39 are surfaces perpendicular to the surface 16a in the installed state.

The sheet metal frame 8 is formed by combining the first plate 33, the second plate 34, and the third plate 35. The lower surface 23, the upper surface 36, and the side surface 37 are included in the first plate 33. The side surface 38 is included in the second plate 34. The side surface 39 is included in the third plate 35.

The grid 25, the protruding portion 27, the inclined portion 28, and the drain hole 26 are collectively formed on the lower surface 23 as one surface. Compared with the case where the parts are scattered on multiple surfaces, the bathroom dryer 1 gathers the parts that need to be formed on the bottom surface 23, thereby reducing the manufacturing cost.

According to the first embodiment, the bathroom dryer 1 is provided on the lower surface 23 with the protrusion 27 having the first surface 31 perpendicular to the lower surface 23, so that even if no work is added to the work to prevent the bathroom dryer 1 from falling, It can be prevented from falling from the frame material 16 provided in the opening 20. Thereby, the bathroom dryer 1 exerts the effect described below: it is possible to prevent the bathroom dryer from falling from the opening 20 without making the work of installing it in the opening 20 provided in the building material cumbersome.

The configuration shown in the above embodiment is an example of the content of the present invention, which can be combined with other known technologies, and part of the configuration can be omitted or changed without departing from the gist of the present invention.
