Abstract

The invention discloses an ultrasonic self-cleaned extractor hood and a method thereof. The ultrasonic self-cleaned extractor hood comprises a controller, a machine shell and a centrifugal fan arranged in the machine shell. A cleaning liquid sucking and discharging pump and a cleaning liquid sucking and discharging port are formed in the machine shell. One connector of the cleaning liquid sucking and discharging pump communicates with the cleaning liquid sucking and discharging port through a pipeline. The other connector of the cleaning liquid sucking and discharging pump directly communicates with the bottom of a volute through a pipeline. At least two through holes are formed in the bottom of the volute. Ultrasonic transducers are fixed to the lower sides of the through holes. The fan, the cleaning liquid sucking and discharging pump and the ultrasonic transducers are connected with the controller. The problem that an extractor hood in the prior art is hard to clean or the cleaning effect is not ideal is effectively solved. The ultrasonic self-cleaned extractor hood is high in automation degree, automation cleaning of the extractor hood is truly achieved, and very high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an ultrasonic self-cleaning range hood which uses ultrasonic waves to self-clean the range hood and a method thereof. Background technique [0002] The range hood has become an indispensable kitchen tool in modern home cooking, but due to the objective use environment and product structure limitations, after the range hood has been used for a period of time, the impeller and the inside of the volute in the suction and exhaust system will be damaged due to wear and tear during use. Oil fume contact will absorb a lot of oil stains. The longer the time, the more difficult it is to clean up the formed oil stains. This requires regular dismantling and comprehensive cleaning. Otherwise, the load on the suction and exhaust system of the whole machine will easily increase, and the performance indicators will decline. Specifically reflected in the decline in suction, increased noise a...
