Description

[Detailed explanation of the invention] This invention relates to a ventilation fan that is installed buried in the wall.
In particular, the installation is characterized by the attachment mechanism of the front decorative cover, which gives a beautiful appearance.

When installing a ventilation fan that is mounted on a wall and uses an electric motor to force intake or exhaust air, the ventilation fan body is inserted and fixed into a mounting hole drilled in the wall, and then a front decoration is installed to cover up any irregularities on the edges of the mounting hole. When installing the cover, if the periphery of this front decorative cover does not fit tightly to the wall surface, the decorative effect will be impaired and the installation will not be able to create a clean appearance. Air leaks from the gap between the air conditioner and the wall surface, and dust in the airflow leaking from this gap causes problems such as dirt on the wall surface during use over time.

Therefore, the present invention proposes an effective attachment mechanism for improving the adhesion of the front decorative cover to the wall surface of such a wall-mounted ventilation fan.

Hereinafter, the gist of the device of the present invention will be explained in more detail with reference to the illustrated embodiments.

Fig. 1 is a front view showing how the ventilation fan of the present invention is installed, and Fig. 2 is a partially longitudinal side view showing an embodiment of the ventilation fan of the present invention, showing the ventilation fan main body 3 equipped with an electric motor 1, a fan 2, etc. The front end edge is fitted with a flange edge 5 that comes into contact with the wall surface of the wall 4.

An inner edge 6 is provided inside the main body 3 at a position lower than the flange edge 5, and a side edge of a filter 8 removably fixed to a support 7 in the center of the main body 3 is attached thereto. be.

Small holes are bored in several places on this inner edge 6, and nuts 9 with washers are mounted on the back side of the holes with screws 10.

A long leg screw 12 inserted from a predetermined position of the front decorative cover 11 is screwed into a nut 9 with a washer provided on the inner edge 6.

According to the ventilation fan of the present invention having such a configuration, after the ventilation fan main body 3 is fitted and fixed into the wall hole, the front decorative cover 11 is attached to the inner edge 6 with the long leg screws 12.

In order to install this front decorative cover 11, the inner edge 6 is installed at a position lower than the flange edge 5 that contacts the wall surface, the filter 8 is attached to this depressed step, and the long leg screw is inserted through this inner edge 6. 12 is not tightened so that it can be inserted, so the front decorative cover 11 can be sufficiently pressed against the ventilation fan main body 3 side, that is, the wall surface for installation. Even if the contact surface of the front decorative cover 11 lacks smoothness due to disturbance or waving of the wall surface itself, the front decorative cover 110 can be prevented from touching the wall surface by tightening the long leg screws 12 at the tip. can be kept secret.

Therefore, the ventilation fan of the present invention can be brought into close contact with the wall surface by fully pulling the front decorative cover toward the ventilation fan body, making it possible to create a clean finished appearance when installing the ventilation fan, and also to make the installation work on the wall surface. The ventilation fan of the present invention has outstanding effects, such as being able to prevent gap air flow and preventing wall stains.
