Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a range hood that is installed, for example, above a microwave oven in a kitchen.

[Background of the invention]

In this type of range hood, attempts have been made to install a grease filter inside the main body cabinet in order to collect oil smoke. This grease filter becomes contaminated with oil smoke, so it must be cleaned regularly. In the kitchen, it is best to use the sink to clean the grease filter. Furthermore, there is an extremely high risk that the grease filter will be damaged if its central portion is bent during cleaning.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a range hood in which the grease filter can be easily washed in a sink without bending.

[Summary of the invention]

The gist of the present invention is to house a fan device in a fan chamber formed within the main body cabinet,
In this range hood that guides the air discharged by the impeller of the fan device from the fan chamber to the duct and exhausts it outdoors, a grease filter is detachably provided at the suction port of the fan chamber, and this grease filter is divided into a plurality of parts. The point lies in the structure.

[Embodiment of the Invention] 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. At the rear of this main body cabinet 1 is a partition plate 5.
A fan chamber 6 is constituted by the partition plate 5, the rear plate part 4, and the upper plate part 3. 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 suction port of a fan formed in the partition plate 5.
Reference numerals 11a and 11b are two grease filters provided between the two opposing side plates 2 of the main body cabinet 1, and provided on the support fittings 12 provided on the partition plate 5 and the horizontal partition plate 13, and from the leaf springs etc. It is removably attached using an elastic support fitting 14 such that the upper part thereof is tilted toward the front. When removing the grease filters 11a, 11b, use the handle 1 provided at the lower end of the grease filters 11a, 11b.
5 and grease filters 11a and 11b.
This can be easily done by pulling up in the direction of the arrow and rotating it as shown by the two-dot chain line. Reference numeral 16 denotes a front cover rotatably attached to the front end of the upper plate 3 by a hinge 17. An operation box 18 is provided at the lower end of the front cover 16, and an auxiliary intake hole 1 is provided at the upper part.
9 is provided. Reference numeral 20 indicates a plurality of switches disposed within the operation box 18 for switching the rotational speed of the motor 7 between high, medium, and low speeds. When the front cover 16 is attached, the front cover 16 should be in contact with the packing 21 provided at the front end of the horizontal partition plate 13 as shown in the figure, and in this state, the lower part of the horizontal partition plate 13 is the main intake part 22, and the upper part is the The auxiliary intake chamber 23 is configured. Kono Packing 2
1 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.
Reference numeral 25 designates an electrical component such as a transformer located at the rear of the auxiliary intake chamber 23 and mounted on the horizontal partition plate 13. This transformer 25 is provided to open a gas stove (not shown) connected to a gas stove when the range hood is turned on. Reference numeral 26 indicates a hole for connecting a duct provided in each side plate 2, and reference numeral 27 indicates a duct hole attached to the upper plate 3 for connecting an exhaust duct (not shown). Reference numeral 28 denotes a recess provided over the entire width L at the upper end of the rear plate 4, and a mounting bracket 29 for the main body is provided over the entire width L 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 is depression 2
Indicates the depth of 8. 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 has an inclined part 31 that slopes downward as it approaches 4, and the grease filter 1
The oil droplets dripping from 1a and 11b fall onto this inclined part 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 the 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, into which the cord 35 connecting the transformer 25 and the switch 20 is inserted and held. 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. It is something to do. 38 is a felt pasted over the entire circumference of this holding groove 34;
Reference numeral 9 indicates a cord drawn out from the transformer 25 and connected to external radio waves, 40 indicates a support rod of the front cover 16 on the front panel 41 of the operation box 18, and 42 indicates a cord holding fitting inserted into the cord holding groove 34. When the switch 20 is operated to operate the motor 7, the oil smoke etc. coming out of the gas range rises and reaches the vicinity of the main intake chamber 22 of the range hood. The air containing oil smoke that has reached the vicinity of the main intake chamber 22 is sucked by the impeller 9 through the grease filters 11a, 11b, the oil smoke is collected by the grease filters 11a, 11b, and the clean air is passed through the impeller 9, for example, through the duct hole. The air is exhausted from a duct etc. attached to 27. On the other hand, the air containing dilute oil smoke that leaves the air passage sucked into the main intake chamber 22 rises to the ceiling, and the air stagnant on the ceiling is sucked in through the auxiliary intake holes 19, and the air vents opened in the horizontal partition plate 13. 2
4 and reaches the fan chamber 6, where it is similarly exhausted to the outside by the impeller 9. This dilute oil smoke is very dilute and there is no problem even if it is directly exhausted without passing through the grease filters 11a and 11b.

After using the range hood for a certain period of time, open the front cover 16 and remove the grease filters 11a, 1.
1b from the main cabinet 1,
Pour it into the kitchen sink. Grease filter 11
Since a and 11b have a two-layer structure instead of a single-layer structure, the overall size is smaller and it is easier to put them into the sink, so they can be easily washed in the sink. Further, since the grease filters 11a and 11b are configured with two sheets, the overall size is reduced and the strength is increased. Therefore, the grease filters 11a, 11b
has a small deflection in the center and is hardly damaged during cleaning.

In the above embodiment, the grease filters 11a, 1
Although the configuration has been described in which the grease filter 1b is divided into two parts, there is no problem even if the grease filters 11a and 11b are divided into three or more parts.

As described above, according to the present invention, there is provided a range hood in which the grease filter can be easily washed in the sink without bending.
