Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood which is installed above a cooking device to remove oil fumes generated during cooking and exhaust odors to the outside of a room.

[0002]

2. Description of the Related Art In recent years, a range hood that is exposed to oil smoke directly and is easily soiled must be frequently cleaned. Therefore, there has been a demand for a range hood that is not easily soiled and is easy to clean.

A conventional range hood will be described below with reference to FIG. As shown in the figure, the hood body 1 is provided above the cooking device 101 and has front and bottom surfaces opened.
In the inside of 02, a grease filter 103 was provided in front of the suction port, a blower 104 having an exhaust duct was provided, and a front hood 105 covering a front opening was provided at the front part of the hood main body 102.

With the above structure, the blower 104 is used during cooking.
The oil smoke sucked by is passed through the grease filter 103, is sucked by the blower 104, and is exhausted to the outside through the exhaust duct 106. The grease filter 103 contaminated with oil smoke was removed during cleaning, and at the same time, the oil content not collected by the grease filter 103 and adhering to the inside of the hood body 102 was disassembled and cleaned.

[0005]

In such a conventional range hood structure, the dirt in the hood body 102 is hard to be removed by simply removing the grease filter 103 to clean the dirty portion. There was a problem that the range hood had to be disassembled.

SUMMARY OF THE INVENTION The first object of the present invention is to provide a range hood that solves the above-mentioned problems and reduces the amount of oil adhered to the inside of the hood body and improves the efficiency of cleaning.

A second object is to spray mist-like water to wash away dirt so that the range hood is always kept clean without disassembling.

[0008]

In order to achieve the above first object, the range hood of the present invention has a hood body having a lower surface and a front surface opened, and a suction port inside the hood body. An air blower that is opened so that the exhaust port communicates with the outside through a duct, a two-layer filter provided opposite to the suction port of the blower, and a front hood that covers the front opening of the hood body. The two-layer filter has a structure in which two filter plates formed by cutting and raising a plurality of openings on the surface are provided so as to face each other with the openings being offset.

Further, in order to achieve the second object, the second
Means comprises a water supply pipe provided with a nozzle for spraying cleaning water between the layers of the two-layer structure filter, a tray provided below the two-layer structure filter, and a drain pipe provided in the tray. .

[0010]

According to the present invention, by the structure of the above-mentioned first means, the oil smoke generated during cooking is sucked into the main body by the blower, and the openings formed by cutting and raising the surface are shifted in position. Since it is absorbed by the two-layer structure filter, the amount of oil adhered to the inside of the hood body can be reduced.

Further, by the constitution of the above-mentioned second means,
The mist-like cleaning water ejected from the spray nozzle cleans the space between the two filter plates of the two-layer structure filter, and prevents the leakage from the opening to the outside of the two-layer structure filter by blocking and raising the sewage. As a result, it will flow down the inside of the two-layer filter, collect in the pan, and then be discharged from the drain pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, a suction port 3 is opened inside the hood body 2 inside the hood body 2 which is opened above the cooking device 1 at the front and bottom surfaces, and an exhaust port 4 is provided at the exhaust duct 5. A blower 6 to be connected is provided, and a plurality of openings 7 are cut and raised on the surface so as to face the suction port 3 of the blower 6.
A pair of grease filter plates 9A and 9 formed by
A front hood 10 that covers the front opening of the hood body 2 is provided by providing a two-layer structure filter 9 in which B is made to face each other by shifting the position of the opening portion 7 with a gap therebetween.
Is provided.

In the above structure, when the range hood is operated during cooking, oil smoke generated from the cooker 1 is sucked into the hood body 2 through the front and bottom openings of the hood body 2 together with air, and the two-layer filter 9 is used. And is sucked into the suction port 3 of the blower 6. And 2
When passing through the layered filter 9, the oil smoke passing through the opening 7 of the grease filter plate 9A of the two-layered filter 9 once collides with the inner surface of the other grease filter plate 9B, and then the other grease filter 9B. Since most of the oil contained in the oil smoke adheres to the inner surface of the grease filter plate 9B which has collided and the inner surface of the grease filter plate 9A which has rebounded and collided, the oil content is The air in the reduced state is sucked into the blower 6 and discharged through the exhaust duct 5 to the outside of the room.

As described above, according to the range hood of the first embodiment of the present invention, most of the oil contained in the oil smoke generated during cooking is collected in the two-layer filter 9, and the air in the state where the oil is reduced is collected. To the blower 6, the amount of oil adhered to the inside of the hood body 2 including the blower 6 is greatly reduced, and the inside of the hood body 2 can always be kept clean simply by cleaning the two-layer filter 9. The cleaning efficiency can be improved.

The second embodiment of the present invention will be described below with reference to FIG. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in the figure, this embodiment is different from the first embodiment in that a water supply pipe 2 for supplying cleaning water into the hood body 2 is provided.
0, and a nozzle 21 for spraying cleaning water between the layers of the two-layer filter 9 is provided at the tip of the water supply pipe 20,
A saucer 2 for receiving dirty water below the two-layer filter 9
3 and the drain pipe 22 for discharging the waste water collected in the tray 23 to the outside.

In the above structure, the two-layer structure filter 9
When a large amount of oil adheres between the layers of No. 1 and the exhaust efficiency of the range hood is reduced, when the cleaning water is sprayed from the nozzle 21, the cleaning water becomes mist and adheres to the inner wall surface of the two-layer filter 9. While efficiently cleaning the collected oil and turning it into sewage, it flows down the inner wall surface of the two-layer filter 9 and is received by the tray 23 and then discharged from the drain pipe 22. .

Further, the mist-like cleaning water sprayed between the layers of the two-layer structure filter 9 and the dirty water at the time of cleaning are discharged from the openings (not shown) formed in the two-layer structure filter 9 into the two-layer structure filter 9. Leakage to the outside can be prevented by a cut-and-raised part (not shown).

As described above, according to the range hood of the second embodiment of the present invention, the oil collected in the two-layer filter 9 can be washed with the washing water, so that the two-layer filter 9 can be removed. The two-layer filter 9 and the inside of the hood body 2 can always be kept clean even if they are not washed.
It is possible to prevent leakage from the layers of the layered structure filter 9 to the outside and stain the cooking device 1 and the like.

[0021]

As is apparent from the above-described embodiments, according to the present invention, the hood body is provided with the blower and the two-layer structure filter in which the opening portion of the surface of the grease filter is cut and raised. It is possible to provide a range hood in which the amount of oily smoke adhering to the inside of the range hood is reduced and the efficiency of cleaning can be improved.

Further, by spraying the cleaning water between the layers of the two-layer structure filter and discharging the cleaning water from the layers of the two-layer structure filter without leaking to the outside, it is always clean without disassembling the range hood. Can be left in a state.
