Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ventilation fan that exhausts oily smoke and the like generated during cooking to the outside.

Conventional technology In general, ventilation fans in the kitchen that exhaust oil smoke generated during cooking and prevent the indoor air from becoming polluted are heavily contaminated due to the adhesion of oil and dust.
It is necessary to clean frequently. In order to save this cleaning effort, conventional ventilation fans of this type have a fan guide section installed on the intake side of a frame 32 inserted into an opening in a kitchen wall 31, as shown in FIG. A filter 3 is placed on the front surface of the cover 33 having
A filter frame 34 housing the filter 4a is detachably provided. Furthermore, since this type of ventilation fan is installed at a high place, an arm 35 is provided at the lower end of the filter frame 34 that extends downward, so that when the filter frame 34 is attached or detached for cleaning, it can be installed on the floor without using a step stool. It was made so that it could be handled from the front.

Problems to be Solved by the Invention In such a conventional configuration, the filter frame 34 is in a position protruding from the wall 31, and therefore the arm 35 is in a position away from the wall 31. Therefore, it is difficult to attach the filter frame 34 to the cover 33. However, as shown in FIG. 4, if too much force is applied to the arm by mistake, the arm may be bent or the filter frame 34 may be damaged. Also, the filter frame 34
Pots and other items were often placed on gas stoves below the stove, which could be dangerous if the person handling them lost their balance by applying too much force.

This invention solves these problems, and even if too much force is applied to the arm, it will not deform,
The purpose is to allow the filter frame to be attached and detached safely without damaging the filter frame.

Means for Solving the Problems In order to achieve the above object, the present invention has a frame body that is installed by inserting an opening in a wall surface and has a motor and blades inside, and a shutter provided on the exhaust side of this frame body. a cover having a fan guide section provided on the intake side of the frame; a filter frame detachably provided on the front surface of the cover; an arm extending downward and having a lower end bent toward the wall surface so as to be movable up and down; the filter frame is detachably attached by operating the arm; and the filter frame is attached. At this point, the bent end of the arm is brought close to the wall surface.

Function The present invention has the above-mentioned configuration, so that the vicinity of the lower end of the arm held to attach and detach the filter frame while standing on the floor is bent toward the wall surface, and the bent end is bent at the point when the filter frame is attached. Since the arm is close to the wall surface, even if too much force is applied to the arm when attaching the filter frame, the arm will not be bent or the filter frame will be damaged.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in the figure, a frame 1 installed by being inserted into an opening in a kitchen wall 11 includes a motor 3 supported horizontally by a support arm 2 and a blade 4 fixed to the motor 3. and a cover 6 having a shutter 5 on the exhaust side and a fan guide section on the intake side.
It is equipped with The cover 6 is provided with locking holes 7 at the upper and lower parts thereof, has locking claws 8 that lock into the locking holes 7, and has a filter frame 9 in which a filter 9a is housed on the front surface thereof. This filter frame 9 is removably provided at its lower end, extends downward as far as it can be reached by standing on the floor, and is bent near the lower end toward the wall 11, with the bent end 10a When the filter frame 9 is attached to the cover 6, it is configured to be detachable by operating an arm 10 that is brought close to a wall 11.

With this configuration, oil smoke generated during cooking is discharged outdoors through the filter 9a, and most of the oil dust is attached to the filter 9a. When the filter 9a becomes very dirty and you want to remove the filter frame 9 for cleaning, pull the arm 10 toward you to remove the locking claw 8 of the filter frame 9 from the locking hole 7 at the bottom of the cover 6, and then It can be removed by lifting 10 upward and releasing the engagement between the upper engagement hole 7 and the engagement claw 8. On the other hand, when the filter frame 9 is to be attached to the cover 6 after cleaning, it is sufficient to carry out the procedure in the reverse order of the above-mentioned removal process. It is difficult to apply enough force. However, the bent end 10a of the lower part of the arm 10
is close to the wall 11, so even if too much force is applied, the arm 10 will hit the wall 11 and will not move any further, and the arm 10 will not bend or the filter frame 9 will be damaged.

As described above, according to this embodiment, the filter frame 9
Even if you apply too much force to the arm 10 when attaching the holder or accidentally push the arm 10 too hard during cooking, the arm 10 will not be bent or the filter frame 9 will be damaged, and the arm 10 is necessary. As described above, it is safe for the person who handles the food by moving toward the wall 11 side without losing his/her balance, and furthermore, since the lower end of the arm 10 near the cooking table is closer to the wall 11 side, there is less dirt caused by oil smoke.

Effects of the Invention As is clear from the above embodiments, according to the present invention, when attaching a filter frame to a cover by holding the lower part of the arm provided at the lower end and extending downward while standing on the floor, etc. Even if too much force is applied to the lower part of the arm in the direction of the wall, the bent end will not hit the wall and deform the arm or damage the filter frame, and it can be handled safely. You can get the effect of
