Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a main unit attached to a building frame at a location behind a ceiling of a bathroom, and an air intake / exhaust device arranged on the inner surface of the bathroom corresponding to a bathroom side opening of the main unit. The present invention relates to a seal structure in a bathroom heater comprising:

[0002]

2. Description of the Related Art Such a bathroom heater is usually hung from a ceiling slab or the like, which is a frame of a building, at a location behind the ceiling of the bathroom by hanging bolts. Is a humid bathroom,
A seal structure for preventing the air in the bathroom containing much moisture and the humid air flowing through the main unit from leaking to the ceiling is indispensable, and the structure shown in FIG. 10 is conventionally used. It had been.

That is, conventionally, the bathroom A of the main unit 1 is
A flange F protruding outward is provided around the bathroom-side opening facing the bathroom, and at the time of initial installation in which a bathroom heater is installed at the time of bathroom installation, as shown in FIG.
A sealing material FS is adhered to the lower surface of the flange F, and the length of the suspension bolt 16 is adjusted so that the sealing material FS is provided between the flange F and the back surface of the ceiling plate 13a of the ceiling 13.
In this state, the flange F is applied to the back surface of the ceiling plate 13a for sealing.

[0004] In addition, at the time of retrofit installation in which a bathroom heater is installed in an existing bathroom, a sealing material FS is stuck on the upper surface of the flange F as shown in FIG. By adjusting the length of the suspension bolt 16, the flange F is applied to the inner surface of the ceiling plate 13a for sealing while the sealing material FS is interposed between the flange F and the inner surface of the ceiling plate 13a.

[0005]

However, in the case of the pre-installation shown in FIG. 10A, the sealing material FS is applied to the back surface of the ceiling plate 13a. Not only is it necessary to partially remove the gypsum board 13b on the back surface of the ceiling plate 13a, but also it is difficult to adjust the length of the suspension bolts 16. For example, if it is too short, the space between the flange F and the ceiling plate 13a is sealed as desired. On the contrary, if the length is too long, the load of the main body device 1 acts on the ceiling plate 13a, causing a problem that the ceiling 13 is deformed. Similarly, FIG.
In the case of retrofitting as shown in (b) of FIG.
6 is difficult to adjust the length, if too long, the space between the flange F and the ceiling plate 13a is not sealed as desired, and if too short,
The main device 1 lifts the ceiling plate 13a upward, and
There is a disadvantage that the deformation of No. 3 is caused.

As described above, in the conventional sealing structure, it is difficult to adjust the length of the suspension bolt both in the case of initial installation and in the case of retrofitting, and the suspension bolt is located behind the ceiling of the bathroom. It is difficult to adjust the length, and in some cases, the ceiling may be deformed, which leaves room for improvement.

[0007] The present invention focuses on such conventional problems, and its object is to enable installation from the bathroom side regardless of pre-installation or post-installation, and to accompany the deformation of the ceiling. Another object of the present invention is to provide a seal structure for a bathroom heater that can easily and surely seal the main unit of the heater and the bathroom ceiling.

[0008]

In order to achieve this object, according to the first aspect of the present invention, a main unit attached to a building frame at a location behind a ceiling of a bathroom, and a bathroom side opening of the main unit. A sealing structure in a bathroom heater including an intake / exhaust surface body disposed on the bathroom surface side in a position corresponding to the part, and sealed with a sealing material with respect to a bathroom-side opening of the main unit. In a state where the cylindrical part is fitted so that the position can be adjusted and fixed in the thickness direction of the bathroom ceiling,
A flange that is applied to the inner surface of the bathroom while being sealed with a sealing material is provided on the front body.

[0009] That is, a covering body disposed on the surface side of the bathroom in a position corresponding to the opening on the bathroom side of the main body device, a tubular portion sealed with a sealing material with respect to the opening on the bathroom side, A flange portion is provided to be applied to the inner surface portion while being sealed with a sealing material, and the cylindrical portion is configured to be adjustable in position in the thickness direction of the ceiling. The cover is moved in the thickness direction to adjust the position, the flange is applied to the surface of the bathroom so that the inner surface of the bathroom is sealed with a sealing material, and the cover is fixed at that position. By doing so, sealing work can be performed as desired. Therefore,
Unlike the past, there is no need to adjust the length of the suspension bolts delicately behind the ceiling of the bathroom, and it is possible to perform sealing work from the bathroom side regardless of whether it is installed first or retrofitted. Sealing can be performed easily and reliably without deformation of the ceiling.

[0010] According to the second aspect of the present invention, the main body device is attached to the frame of the building at a location behind the ceiling of the bathroom, and the main body device is disposed on the inner side of the bathroom so as to correspond to the opening on the bathroom side. A sealing structure in a bathroom heater including an intake / exhaust body and a position adjustment fixed in a thickness direction of a bathroom ceiling in a state of being sealed with a sealing material with respect to a bathroom side opening of the main body device. A relay frame body provided with a tubular portion that is freely fitted and a flange portion that is applied to the inner surface of the bathroom while being sealed with a sealing material is provided, and the cover body is provided with the relay frame. Attached to the body.

[0011] That is, there is provided a cylindrical portion which is sealed by a sealing material with respect to the bathroom side opening of the main body device, and a flange portion which is affixed to the inner surface of the bathroom while being sealed by the sealing material. Since the relay frame body is provided, and the cylindrical portion is configured to be position-adjustable and fixed in the thickness direction of the ceiling, the relay frame body is moved from the bathroom side in the thickness direction of the bathroom ceiling to adjust the position. Then, the flange is applied to the interior of the bathroom so that the inner surface of the bathroom is sealed with a sealing material, and the relay frame is fixed at that position. By attaching the body,
Sealing work can be performed as desired. Therefore, there is no need to adjust the length of the suspension bolts delicately above the ceiling of the bathroom, as in the past, and it is possible to perform sealing work from the bathroom side regardless of whether it is pre-installed or retrofitted, Construction is easy, and sealing can be reliably performed without deformation of the ceiling.

According to the third aspect of the present invention, the ventilation portion forming body of the front body is detachably configured, and the adjusting opening is formed in a state where the ventilation portion forming body is detached. It is configured as follows.

Therefore, at the time of the above-mentioned sealing work, the ventilation part forming body can be detached from the front body, the hand can be inserted through the adjustment opening, and the sealing work can be easily performed. Also, the maintenance work can be easily performed from the bathroom side using the adjustment opening.
