Abstract

PURPOSE:To keep a ventilating fan fixed on a wall, in facilitating its cleaning, from being soiled at the part exposed to the room by sooty fumes from kitchen utensils. CONSTITUTION:The orifice 3, which is a part of the main body 2 of a ventilating fan set in a wall and which is exposed to the room, is covered entirely with a filter in order to prevent the fan from being soiled at its orifice 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan with a filter that is attached to a wall of a kitchen and that attaches and removes oily smoke generated during cooking.

0002

BACKGROUND OF THE INVENTION In recent years, most ventilation fans used in kitchens are equipped with a filter on the suction side to prevent the ventilation fan from being contaminated by oily smoke generated during cooking.

A conventional ventilation fan with a filter of this type will be explained with reference to FIGS. 5 and 6.

As shown in the figure, a fan motor 31 is installed inside.
An orifice 33 provided on the suction side of a ventilation fan main body 32 having a main body 32 has a partially opened front and left and right side surfaces, and a substantially U-shaped filter 34 is removably provided in this opening.

[0005]

[Problems to be Solved by the Invention] In the configuration of such a conventional ventilation fan with a filter, the lower and upper parts of the orifice 33 and a portion of the left and right sides are exposed, so that it is difficult to ventilate oily smoke generated during cooking. There are problems in that dirt such as oil adheres to the exposed portion of the orifice 33 and oil adhered to the filter 34 falls onto the cooking table.

[0006] The present invention solves the above-mentioned problems, and its first object is to provide a ventilation fan with a filter that can prevent contamination of the orifice portion on the indoor side of the ventilation fan body attached to the wall. do. A second object is to provide a ventilation fan with a filter that prevents oil adhering to the filter from falling onto the cooking table.

[0007]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the ventilation fan with a filter of the present invention has a first means in which a filter is provided on a wall and has a shape that covers the exposed indoor side of the ventilation fan body, and is detachable. The configuration is as follows.

[0008] The second means includes a removably installed filter that is provided on the wall and covers the exposed indoor side of the ventilation fan main body, and a filter that is removably installed on the ventilation fan main body below the filter. and an oil receiver, and the filter is configured to be reduced in size so that the lower part of the filter is inserted into the oil receiver.

[0009]

[Function] According to the above-mentioned first means, the filter-equipped ventilation fan of the present invention covers all the parts exposed indoors with the filter when ventilating oily smoke, so that the exposed parts of the ventilation fan indoors do not get dirty. There is no.

Furthermore, by the second means, the lower part of the filter is reduced so that oil adhering to the filter flows into the oil pan, thereby preventing oil from falling onto the cooking table.

[0011]

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

As shown in the figure, a fan motor 1 is installed on the suction side of a ventilation fan main body 2 which has a fan motor 1 built therein.
A filter 5 is formed integrally with a filter frame 4 so as to surround the orifice 3, and is detachably attached to the orifice 3.

The ventilation fan main body 2 having the above structure is attached to a ventilation hole (not shown) formed in a wall, the orifice 3 is exposed to the indoor side, and the orifice 3 is surrounded by a filter 5. When the fan motor 1 is operated, when the air containing oily smoke generated from the cooking table etc. passes through the filter 5, the oily smoke is collected by the filter 5, and the purified air is transferred to the ventilation fan body 2.
It passes through the interior and is discharged outside. Therefore, oil smoke does not adhere to the orifice 3 exposed to the indoor side, and the inside of the ventilation fan body 2 is also free from contamination because purified air passes through it. When oil smoke accumulates in the filter 5, cleaning or replacing the filter 5 can prevent the ventilation fan main body 2 including the orifice 3 from becoming dirty.

(Embodiment 2) Embodiment 2 of the present invention will be described below with reference to FIGS. 3 and 4.

As shown in the figure, a fan motor 11 is installed inside.
An orifice 13 serving as the wind barrel of the fan motor 11 is provided on the suction side of a ventilation fan main body 12 having a built-in ventilator, and a filter 15 integrally molded with a filter frame 14 is formed to surround this orifice 13. The lower part of the filter 15 is inclined to form a reduced portion 17 so as to be inserted into an oil receiver 16 detachably provided on the ventilation fan main body 12.

The ventilation fan main body 12 having the above structure is attached to a ventilation hole (not shown) formed in a wall, and the orifice 1
3 is exposed to the indoor side, the orifice 13 is surrounded by a filter 15, and an oil receiver 16 is attached to the ventilation fan body 12 so that the lower reduced part 17 of the filter 15 is inserted.

Then, when the fan motor 11 is operated,
When air containing oily smoke generated from a cooking table or the like passes through the filter 15, the oily smoke is collected by the filter 15, and the purified air passes through the ventilation fan body 12 and is discharged to the outside. Therefore, oil smoke does not adhere to the orifice 13 exposed on the indoor side, and the inside of the ventilation fan body 12 is also free from contamination because purified air passes through it.

The oil smoke collected by the filter 15 eventually moves downward and falls from the reduced portion 17 formed at the bottom of the filter 15 into the oil pan 16, where oil is collected and is directly removed from the filter 15 for cooking. This prevents oil from falling onto the table.

[0019]

[Effects of the Invention] As is clear from the above embodiments, according to the present invention, since the indoor exposed portion of the ventilation fan is covered with a filter, the indoor exposed portion of the ventilation fan is not contaminated with oil, and the filter It is possible to provide a ventilation fan with a filter that can prevent the indoor exposed part of the ventilation fan from getting dirty by cleaning and replacement, and improves cleaning performance.

Furthermore, it is possible to provide a ventilation fan with a filter that can prevent oil from falling from the filter onto the cooking table by guiding the oil to the oil receiver.
