Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a ventilation fan used in a kitchen or the like, and relates to a ventilation fan in which an oil pan for collecting oil dripping from a front cover can be easily attached and detached.

[Background of the idea]

The oil receiver of conventional ventilation fans was attached to a cover using elasticity, so when it was removed, a shock was applied to the oil receiver, causing the oil accumulated in the oil receiver to scatter.

[Purpose of invention]

The purpose of this invention is to make it possible to install the oil receiver by simply inserting the hook of the oil receiver into the protruding parts provided on the main body and cover.
To provide a ventilation fan with an oil pan that does not apply impact when removing the oil pan and can prevent oil from scattering.

[Summary of the idea]

In order to improve the handling of the oil pan, it is impossible to attach the oil pan using elasticity, so we recommend using a hooking method that does not use elasticity (by forming a protrusion on the main body or cover). (A corresponding hook is provided on the oil receiving part.) This prevents oil from scattering by preventing shock from being applied when removing the oil receiving part. Furthermore, with the above-described configuration, the oil receiver can be easily attached and removed.

[An example of the idea]

An embodiment of the present invention will be described below with reference to the drawings.
Reference numeral 1 denotes a ventilation fan main body, and a filter frame 3 holding a filter 2 on the front surface and a filter frame 4 sandwiching the filter 2 between the filter frame 3 are each attached to a cover 5 of the ventilation fan main body 1 by elasticity. A protrusion 6 is provided on the lower side of the filter frame 3.
is provided, and the hook part 8 of the oil receiver 7 engages with the oil receiver 7.
can be installed. Furthermore, protruding guide portions 9 and 10 are provided on the lower side surfaces of each filter frame 3 and 4, and serve as sliding guides when the oil receiver portion 7 is attached.

The protruding guide portions 9 and 10 are provided approximately parallel to the installation guide portion 11 provided on the upper surface of the hook portion 8 of the oil receiver portion 7, so that the oil receiver portion 7 is tilted when the oil receiver portion 7 is attached or removed. You will be able to do it without any problems.

Since the protrusion 6 and the hook part 8 of the oil receiver 7 have the same non-circular shape, the oil receiver 7 can be attached and held without tilting. Further, since the protrusion 6 is provided with a collar 12 to receive the side wall 13 of the oil receiver 7, the oil receiver 7 is prevented from falling off to the outside. When removing the oil pan 7, the guide portion 11 of the oil pan 7 and the protruding guide portions 9 and 10 first come into contact, and after that, all you have to do is pull the oil pan 7 forward, so it can be easily removed and the protrusions 6, the inclination when removing the oil receiver 7 can be minimized.

As described above, according to this embodiment, by using the hook type for the oil receiver, the oil receiver can be easily attached and removed, and no impact is applied to the oil receiver, preventing oil from scattering. There are effects such as

[Effect of idea]

As described above, the present invention includes a protrusion 6 which is integrally formed on the lower end of the side surface of the filter frame 3 and has a flange 12 that protrudes forward; is,
and a protruding guide portion 9 located above the protrusion 6; and a protruding guide portion 10 integrally formed on the side surface of the filter frame 4 at the same horizontal position as the protruding guide portion 9. A key-shaped hook part 8 that engages with the root part of the protrusion 6 is integrally formed at the rear of the upper part of the oil receiver part 7, and the protruding guide parts 9 and 10 continuously connect to the oil receiver part 7. Since it is configured to be slidably guided with the upper guide part 11, the oil receiver part 7 can be easily attached and removed by the guide parts 9, 10, etc., and since it is attached by mere engagement, Since the operating force is very small and uniform compared to an engagement device, it is possible to provide a ventilation fan that does not cause oil to scatter during removal.
