Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, and specifically refers to a range hood that can be opened and cleaned internally. Background Art

[0002] A range hood is a kitchen appliance, which simply means a device for extracting oil fumes. Its function is to purify the air environment in the kitchen and is an indispensable appliance in modern kitchens. The side suction range hood is a machine that uses the technology of sucking air from the side and separating oil fumes to effectively separate the oil fumes, achieving the effect of completely extracting the oil fumes. Its air inlet is closer to the oil fume source, can lock the generated oil fumes in the first time, and can effectively shorten the moving distance of the oil fumes rising, and the smoke exhaust effect is more ideal.

[0003] During the use of the existing range hoods (including side suction range hoods) on the market, the oil fume separation net will accumulate residual oil stains, causing the oil fume separation net to be blocked, and the oil stains will flow to other components of the range hood, polluting the range hood, reducing the air suction efficiency of the range hood, and prone to breeding bacteria, destroying the good sanitary environment, and even affecting people's physical health. However, most of the existing range hoods have a fixed structure. To clean the inside, it is necessary to disassemble the range hood first, which is very troublesome. Summary of the Utility Model

[0024] The present invention will be further described in detail below with reference to the drawings.

[0025] A smoke extractor that can be opened and cleaned internally, as Figure 1 , 2 , shown in Figure 3, includes:

[0026] A smoke extractor housing 1, a smoke extraction duct 5 and an oil tank 11; the smoke extractor housing 1 is the housing of a side suction type smoke extractor. As Figure 4 shown, its inner frame has a certain curvature (as Figure 4 shown, the left and right side plates are bent and recessed inward), and the rear side wall is fixed to the wall. A smoke extraction duct 5 is provided above the smoke extractor housing 1 (the smoke extraction duct 5 includes equipment and structures such as the exhaust fan and check valve of the smoke extractor), and a control panel 4 is also provided at the front top of the smoke extractor housing 1 (to control lighting and the start and stop of the smoke extractor, and the lighting lamp is provided below the control panel 4). An oil tank placement groove 12 is formed at the bottom. The oil tank placement groove 12 is a U-shaped plate structure with an upward opening, and the oil tank 11 is a box body that cooperates with the oil tank placement groove 12 and has an open top, and is placed in the oil tank placement groove 12 in a matching manner.

[0027] An oil fume separation net 7 and a flipping and fixing structure; as Figure 5As shown, the oil fume separation net 7 is an arc-shaped plate structure with a certain curvature, and oil fume separation slots are reserved on the plate surface. The flip fixing structure includes a rotary handle 9 and a C-shaped buckle 10. The rotating shaft 8 is arranged below the top wall of the range hood housing 1, and both ends are respectively rotatably connected to the left and right side walls of the range hood housing 1. The right end of the rotating shaft 8 penetrates through the side wall of the range hood housing 1. A sleeve structure 13 is formed at the top of the oil fume separation net 7, and the sleeve structure 13 is sleeved and fixed on the rotating shaft 8. The C-shaped buckle 10 is an elastic structure fixed on the side wall of the range hood housing 1 and is horizontally arranged with the rotating shaft 8. One end of the rotary handle 9 is hinged to the right end of the rotating shaft 8, and after the other end is engaged in the C-shaped buckle 10, the oil fume separation net 7 is fixed in the range hood housing 1 and covers the inside of the range hood housing 1 (at this time, the bottom end of the oil fume separation net 7 is directly above the oil tank 11).

[0028] The flip-up air suction cover plate includes a front cover plate 2 and an electric telescopic rod 3. The front cover plate 2 is an arc-shaped plate structure with an air suction port 6 reserved and a certain curvature, and the upper end is hinged to the range hood housing 1. An electric telescopic rod 3 is arranged on the left side of the range hood housing 1, and both ends are respectively hinged to the front cover plate 2 and the range hood housing 1. After the electric telescopic rod 3 extends, the front cover plate 2 flips forward, and after the electric telescopic rod 3 contracts, the front cover plate 2 covers and has a clearance fit with the range hood housing 1 to cover the oil fume separation net 7 (after the front cover plate 2 covers, the bottom of the front cover plate 2 is above the oil tank 11).

[0029] The usage method and installation method of the electric telescopic rod 3 are both existing mature technologies.

[0030] In the specific implementation of this embodiment:

[0031] During use, close the flip-up air suction cover plate and turn on the exhaust fan in the smoke exhaust duct 5. Under the action of negative pressure, the oil fume is captured by the range hood and enters the range hood housing 1 through the air suction port 6. When passing through the oil fume separation net 7, the waste oil in the oil fume is filtered and left behind, and flows along the oil fume separation net 7 into the oil tank 11. The flue gas is discharged through the smoke exhaust duct 5. During this process, some oil stains will remain on the inner wall of the oil fume separation net 7, the inner wall of the range hood housing 1, and the inner side wall of the front cover plate 2.

[0032] During cleaning, extend the electric telescopic rod 3 to make the front cover plate 2 flip forward to expose the outer surface of the oil fume separation net 7 and the inner side wall of the front cover plate 2, and clean the two. After cleaning, lift the rotary handle 9 of the flip fixing structure to release its engagement with the C-shaped buckle 10, and then control the oil fume separation net 7 to flip forward through the rotary handle 9 to expose the inner surface of the oil fume separation net 7 and the inner wall of the range hood housing 1, and clean the two. Finally, take out the oil tank 11 for cleaning, and restore the positions of the various components of the range hood after cleaning.

[0033] The above description is made on the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural modes and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
