Description

Technical Field

[0001] The utility model relates to the technical field of smoke hood cleaning, in particular to a variable frequency smoke hood with an automatic cleaning function. Background Art

[0002] The variable frequency hood is a common fume exhaust device in the kitchen. It can absorb and accelerate the exhaust of large amounts of fume generated during cooking, purify the kitchen environment, and prevent the fume from being inhaled by the human body and causing damage. Since the hood absorbs and discharges fume for a long time, the inner wall of the hood will absorb a large amount of oil stains after long-term use.

[0003] After searching, a Chinese patent with publication number CN215765274U discloses a self-cleaning range hood structure, including a hood body and a front plate connected to one side of the hood body, an operation panel is provided on one side of the front plate, a lighting lamp is connected to the bottom of the front plate, and an oil shield is provided at the bottom of the hood body; a liquid spray pipe is provided on one side of the front plate close to the inner cavity of the hood body, an installation cavity for accommodating the liquid spray pipe is provided in the front plate, and a liquid supply mechanism for providing cleaning liquid to the liquid spray pipe is provided in the front plate.

[0004] The device is designed according to existing needs. After the spray pipe provides cleaning liquid through the liquid supply mechanism, the driving mechanism drives the spray pipe to move. The spray pipe can spray cleaning liquid on the oil shielding hood, which is beneficial to the dissolution of oil stains and subsequent cleaning, and avoids the cleaning liquid and oil stains from splashing on personnel when operating the spray operation, which is convenient for cleaning the oil shielding hood. The sealing mechanism can seal the installation cavity to prevent oil smoke from entering the installation cavity when the fume hood is in use, thereby facilitating the use of the fume hood.

[0005] Combining the prior art and the device, it is found that:

[0006] When the device cleans the oil hood, the cleaning liquid can only dissolve on the surface of the oil hood by itself and then flush. In actual use, the hood is prone to residual dirt that is difficult to clean inside, which takes a long time to dissolve, and flushing after dissolution has a poor cleaning effect. Utility Model Content
