Description

Technical Field

[0001] This utility model relates to a range hood. Background Technology

[0002] The existing technology, Chinese patent 202220957777.7, describes a range hood with a cleaning function, including a casing, a fan housing on top of the casing, and a fan inside the fan housing. The fan includes a volute, a centrifugal impeller, and a guide ring on the air inlet of the front volute plate. It also includes an annular light wave tube, located within the guide ring and opposite to the centrifugal impeller. The annular light wave tube allows for direct heating of the volute and centrifugal impeller via light wave irradiation, resulting in rapid heating. This vaporizes the oil or separates the oil from the volute and centrifugal impeller before the centrifugal impeller rotates, achieving rapid cleaning, simplifying the structure, and reducing costs. However, the problem is that the noise generated by the fan's rotation is transmitted into the room through the oil filter in the top smoke collection chamber of the horizontal section, and when stationary, residual oil drips onto the stovetop through the oil filter.
