Description

Fume exhauster Technical Field The utility model relates to the technical field of range hoods, in particular to a range hood. Background The kitchen ventilator is used as kitchen common equipment and mainly comprises a smoke collecting cavity and a box coaming component, and the kitchen ventilator sucks the oil smoke generated in a kitchen through a smoke inlet and then exhausts the oil smoke to the outside through a smoke pipe, so that the air of the kitchen is kept clean. However, in the actual use process, along with the increase of the use time, grease and other components in the oil smoke can be gradually attached to the oil screen at the smoke inlet of the range hood, so that oil dirt accumulation is formed. In order to maintain the normal operation of the range hood, the user needs to frequently clean the oil screen, so that time and energy are consumed, and the use experience of the user is greatly influenced. If the cleaning is not performed for a long time, the greasy dirt components on the surface of the oil screen become more complex, and the conventional cleaning method is difficult to effectively remove, so that the greasy dirt is continuously accumulated, and further the phenomenon that the smoke machine drops oil onto a kitchen table surface occurs, thereby seriously disturbing the kitchen cooking environment. More importantly, the accumulated greasy dirt on the oil screen can block the smoke inlet gap, so that the smoking effect of the smoke ventilator is obviously reduced, the performance of the smoke ventilator is directly influenced, and the smoke purification efficiency of the smoke ventilator is reduced. Therefore, aiming at the technical situations that oil stains on the surface of an oil net are gradually accumulated and difficult to effectively clean in the use process of the existing range hood, and finally the performance of the range hood and the use experience of users are affected, the invention is highly required to be invented for the range hood with the function of automatically cleaning the oil net so as to solve the technical problems.
