Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter holding structure that is easy to attach and detach.

An embodiment of the present invention will be described below based on the drawings.

In the drawings, reference numeral 1 denotes a main body cabinet, which is composed of two opposing side plates 2, a top plate 3, and a rear plate 4.

The rear part of the main body cabinet 1 is partitioned by a partition plate 5, and the partition plate 5, the rear plate part 4, and the upper plate part 3 constitute a fan chamber 6.

The upper plate 3 and the rear plate 4 are integrally formed by bending a steel plate.

Reference numeral 7 denotes a motor fixed to the rear plate 4 with a mounting leg 8, and a turbo-type impeller 9 is fixed to its rotating shaft.

10 is a fan suction port formed in the partition plate 5.

Reference numeral 11 denotes a support fitting 12 provided on the partition plate 5 with a grease filter.
It is provided on the horizontal partition plate 13 and is removably attached so that the upper part thereof is tilted forward by an elastic support fitting 14 made of a leaf spring or the like.

The grease filter 11 can be easily removed by hooking a finger onto the handle 15 provided at the lower end of the grease filter 11, pulling up the grease filter 11 in the direction of the arrow, and rotating it as shown by the two-dot chain line.

A front cover 16 is rotatably attached to the front end of the upper plate 3 by a hinge 17, and an operation box 18 is provided at the lower end of the front cover 16, and an auxiliary intake hole 19 is provided at the upper part.

Reference numeral 20 indicates a plurality of switches arranged in the operation box 18 for switching the rotation speed of the motor 7 between high, medium, and low speeds.

When the front cover 16 is attached, the front cover 1 is attached to the backing 21 provided at the front end of the horizontal partition plate 13 as shown in the figure.
In this state, the lower part of the horizontal partition plate 13 constitutes the main intake part 22, and the upper part constitutes the auxiliary intake chamber 23.

This backing 21 maintains airtightness between the main intake chamber 22 and the auxiliary intake chamber 23.

Reference numeral 24 designates a vent hole opened at the rear of the elastic support fitting 14 of the horizontal partition plate 13.

25 is located in the rear part of the auxiliary intake chamber 23 and is connected to the horizontal partition plate 1.
It is an electrical component such as a transformer installed on 3.

This transformer 25 is provided to open a gas cock (not shown) connected to a gas staple when the range hood is turned on.

26 are holes for connecting ducts provided in each side plate 2, 27
is the duct hole attached to the upper plate 3, and the exhaust duct (
(not shown).

Reference numeral 28 denotes a recess provided over the entire width at the upper end of the rear plate 4, and a mounting bracket 29 for the main body is provided over the entire width so as to fit within this recess 28 or to protrude slightly.

This mounting bracket 29 is used to attach the range hood to the wall W by engaging with a bracket 30 fixed to the wall W to which the range hood is attached.

D indicates the depth of the depression 28. This recessed portion 28 is formed by integrally bending the rear plate 4 made of a steel plate, and is used to increase the strength of the main body and to mount the range hood as close to the wall W as possible. .

The lower part of the partition plate 5 is a sloped part 31 that slopes downward as it approaches the partition plate 4.

Oil droplets dripping from the grease filter 11 reach this inclined portion 3.
The oil is transmitted from one side to the inner surface of the rear plate 4, and finally accumulates in the oil receiving groove 33 formed at the bent portion 32 of the rear plate 4.

Further, this inclined portion 31 greatly contributes to improving the performance of the fan device composed of the turbo-type impeller 9.

That is, the air discharged to the outer periphery by the impeller 9 disposed close to the suction port 10 is smoothly guided and exhausted to the rear of the fan chamber 6 by this inclined portion 31, so that the air is directly below the impeller 9. This improves the performance of the fan device.

Reference numeral 34 is a cord holding groove formed by bending the outer periphery of the front cover 16, and the cord 35 connecting the transformer 25 and the switch 20 is inserted and held therein.

This cord 35 is particularly held along the upper retaining groove 36 and the side retaining groove 37 to prevent the cord 35 from crossing the auxiliary intake hole 19 through which oil dust passes, and to prevent the cord 35 from wobbling. This is something you should do.

38 is a felt pasted around the entire circumference of this holding groove 34; 39 is a cord pulled out from the transformer 25 and connected to external radio waves; 40 is a front panel 41 of the operation box 18 that supports the front cover 16; The rod 42 is the cord holding groove 34
Shows the cord retaining fitting inserted into the.

According to the present invention configured as described above, a filter holding structure with extremely high practical value is provided, such as easy maintenance because the grease filter can be easily removed not only when cleaning the grease filter itself but also during servicing when a morph malfunctions. can.
