Lifting and hidden easy-to-clean self-cleaning range hood

Abstract

The invention discloses a lifting and hidden easy-to-clean self-cleaning range hood. The range hood comprises a range hood body, a first gas outlet pipe, a second gas outlet pipe and a third gas outlet pipe. The first gas outlet pipe is located at the top end of the range hood body, and the bottom end of the first gas outlet pipe communicates with the range hood body; a control valve is arranged above the first gas outlet pipe, one end of the control valve is in communication with the first gas outlet pipe, and the other end of the control valve is in communication with the second gas outlet pipe and the third gas outlet pipe separately; and the range hood further includes a self-cleaning device used for range hood cleaning. According to the scheme, the self-cleaning of the range hood is effectively realized, the staying time of oil fume in the range hood is short, and the cleaning difficulty is relatively low; and the efficiency of the range hood can be greatly improved during the subsequent range hood operation. The structure of the control valve is further improved, the sealing performance of the control valve is improved, and the situation of oil fume backflow is avoided.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a self-cleaning range hood with a lifting and lowering type and easy cleaning.
