Abstract

The invention discloses a self-suction type range hood. The self-suction type range hood comprises a tapered cover with an opening in a lower end, wherein a ring-shaped slot is formed in the side wallof the tapered cover in the peripheral direction; a heat insulating plate is arranged in the ring-shaped slot; a plurality of cylindrical cavities are arranged in peripheral side walls of the taperedcover; inner walls of upper and low openings of each cylindrical cavity are fixedly connected with dustproof nets; cavities of the cylindrical cavities penetrate through the heat insulating plate andextend towards two side walls of the ring-shaped slot; and one side, close to the inner part of a circular table shaped cover, of each cylindrical cavity is fixedly equipped with a heat conducting plate. The self-suction type range hood is novel in idea, and reflects heat generated during dish frying and cooking onto the inner wall of the tapered cover through an infrared reflecting film, so thatcircular-arc-shaped heat dissipation sheets of the heat conduction plates are heated quickly, the control period of a temperature-control sheet is relatively short, an intermittent rotation period ofa rotary barrel is short, and speed is high, and therefore, fan blades are driven to rotate for sucking oil smoke; besides, a rotary mechanism does not need to be driven by a motor, so that obvious noises appear in a working process. The self-suction type range hood does not need external power to drive, so that energy is saved.

Description

Technical field [0001] The invention relates to the technical field of range hoods, in particular to a self-priming range hood. Background technique [0002] Range hoods, also known as range hoods, are kitchen appliances that purify the kitchen environment. It is installed above the kitchen stove, can quickly remove the waste burned by the stove and the harmful fumes generated in the cooking process, and exhaust it outside, reduce pollution, purify the air, and have the safety protection effect of anti-virus and explosion-proof. [0003] Existing household range hoods are all driven by electricity, and the range hood needs to be turned on and off manually every time you cook, which consumes too much energy; in addition, during use, the fan generates a lot of noise, which affects the use experience. Summary of the invention [0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and proposes a self-priming range hood. [0005] In order to...
