Description

[Detailed description of the invention] This invention relates to a mounting device for a side plate that closes a side opening of a frame body, for example, an exhaust device that is placed above a cooking range to exhaust contaminated air rising from the range to the outside. This simplifies the installation of a front plate that closes the front opening of a booth type range hood equipped with a fan.

An embodiment of the present invention will be described below, taking as an example the installation of a front plate that closes the front opening of a range hood.

Reference numeral 1 denotes a range hood frame body having the proposed structure, which frame body includes left and right side plates 3, 3 having flanges 2 formed on their peripheries, an L-shaped frame 4 forming the top and back surfaces, and a board 5 on which electrical components are mounted. The frame body 1 is formed by welding the left and right side plates 3, 3 and the substrate 5 to the above-mentioned cross-shaped frame 4.

In the upper part of the frame 1, there is a fan chamber 7 partitioned by a partition plate 6.
A fan motor 8 is housed in the chamber γ.

An exhaust port 9 is formed at the rear of the chamber 7, and an exhaust frame 10 is attached to the exhaust port 9.

Further, the lower opening of the chamber 7 is closed by a lid 12 in which a wind tunnel 11 is formed so as to be openable and closable.

A suction port 13 formed in the lower part of the frame 1 is closed by a filter 14 for removing oily dirt from exhaust smoke.

A switch 15 for controlling the fan motor 8 and an illumination light 16 are mounted on the board 5 constituting the front lower part of the frame 1, and a cover 17 fixed to the board 5 closes the switch 15 and the illumination light. 16 to prevent exhaust smoke from entering.

18 is a front plate that closes the front opening 19 of the frame 1;
Curled portions 20.20 bent into a cylindrical shape are formed near both sides of the upper part of the front plate 18, and a tongue piece 22 in which an engagement hole 21 is formed protrudes from the center portion.

The curled portions 20 are located near both upper sides of the front opening 19.
, 20, and a guide portion 2 that guides the curled portions 20, 20 to the pivot portions 23, 23.
4. A gutter-shaped pivot tongue piece 25 having elasticity consisting of 24,
25 has been established.

Further, when a recess 26 into which the tongue piece 22 fits is formed at the center of the upper part of the opening 19, a locking protrusion 27 that engages with the engagement hole 21 of the tongue piece 22 is inserted into the recess 26. It protrudes inside.

The protrusion 27 is formed with sloped parts 29, 29 that abut against the edges 28, 28 of the engagement hole 21, and the protrusion 27 is formed in the engagement hole 2.
1 and guide the engagement hole 21 to a predetermined position relative to the protrusion 27.

Next, the installation of the front plate will be explained.

With the front plate 18 tilted at a predetermined angle with respect to the opening 19 of the frame 1, the front plate 18 is moved along the guide portion 24 of the tongue piece 25.
The curled portion 20 is fitted, and the curled portion 20 is pivotally supported by the pivot portion 23 of the tongue piece 25.

After that, the front plate 18 is rotated to close the opening 19,
The lower part of the front plate 18 is fixed to the frame 1 with screws 30, 30.

At this time, the tongue piece 22 is fitted into the recess 26 and at the same time, the engagement hole 21 is locked by the protrusion 27, so that it will not come off even if the front plate 18 is pulled forward.

Further, in this embodiment, since the engagement hole 21 is guided to a predetermined position by the slope portion 29 of the protrusion 27, the tongue piece 22 is pulled inward and pivots with the curl portion 20 when the front plate 18 is attached. The tongue pieces 25 are connected without any looseness.

Therefore, the front plate 18 does not shake or generate abnormal noise due to vibrations of the fan motor or the like.

Further, when removing the front plate 18, the front plate 18 cannot be removed unless the screws 30, 30 are removed, the front plate 18 is opened at a certain angle or more, and the curled portion 20 is pulled along the guide portion 24.

Therefore, unless an attempt is made to remove the front plate 18 for cleaning or the like, it will not come off inadvertently, and operations such as removing the screws 30, 30 can be performed safely.

As described above, in the present invention, a gutter-like pivot tongue piece and a locking part are formed at the upper part of the side opening of the frame body, and a curled part pivotally supported by the tongue piece is formed at the upper part of the side plate that closes the opening. In addition, since the side plate is provided with a protruding engaging portion that engages with the locking portion when the opening is closed by rotating the side plate, the locking portion and the retaining portion are connected in the attached state. The side plates are securely attached to the frame.

Furthermore, since the front plate cannot be removed unless the front plate is rotated by a predetermined angle, each step of the removal work can be carried out safely, which has great practical effects.
