Description

Technical Field

[0001] The invention relates to the technical field of oil fume removal equipment, and in particular to an oil fume, gas and dust removal device. Background Art

[0002] In the prior art, a one-way paddle is provided between the smoke outlet of the range hood and the flue, and the paddle is blown open by the gas exhausted from the range hood. When the range hood is turned off, the paddle is flipped and closed under the action of gravity because the range hood is not working. However, due to long-term use, viscous substances composed of oil smoke adhere to the inside of the flue, causing the paddle to be poorly sealed or unable to be closed. Even if it is closed, the paddle closes automatically under the influence of gravity, resulting in a loose seal, resulting in the smell of food being smelled upstairs while cooking downstairs. Summary of the invention

[0003] The purpose of the present invention is to provide a device for removing oil smoke, gas and dust in view of the problems and shortcomings described in the background technology.

[0004] A device for removing oil smoke, gas and dust, comprising a shell, a hinge shaft, a louver, a baffle, a U-shaped sealing strip, a bellows, a switch, a fixing part, a flue opening, a bellows bottom edge, a shell bottom edge and a sealing part;

[0005] The upper end of the shell is rotatably connected with the lower end of the bellows by a hinge shaft, an arc-shaped bellows lower edge is provided on the smoke inlet side of the bellows, and an arc-shaped shell lower edge is provided on the smoke exhaust side of the shell. The lower edge of the bellows is sealed and overlapped with the lower edge of the shell, and a baffle that can seal the inner wall of the bellows is vertically provided on the upper end of the smoke exhaust side of the shell, and a U-shaped sealing strip is provided on the edge of the baffle. The height of the baffle plus the thickness of the U-shaped sealing strip is slightly larger than the side length of the inner wall of the baffle. A flue port connected to the flue is provided on the bellows, a switch for controlling the operation of the suction fan is provided on the bellows, a suction fan is provided in the flue or the bellows, and a venetian blind is provided at the smoke inlet of the shell. When the shell is in a vertical state, a single blind in the venetian blind is arranged vertically downward. When the bellows and the shell are overlapped, the suction fan rotates, and when the bellows are separated from the shell, the suction fan stops rotating.

[0006] Beneficial effects of the present invention:
