Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0019] refer to Figure 1-3 , a self-priming range hood, comprising a conical hood 5 with an opening at the lower end, an annular groove is arranged in the side wall of the conical hood 5 along its circumference, a heat insulating plate 7 is arranged in the annular groove, and the surroundings of the conical hood 5 The side walls are provided with a plurality of cylindrical cavities, and the inner walls of the upper and lower openings of the cylindrical cavities are fixedly connected with dust-proof nets 11. The cavities of the cylindrical cavities run through the heat insulating plate 7 and extend to the side walls on both sides of the annular groove for heat insulat...

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-suction range hood. Background technique [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the kitchen stove, which can quickly take away the waste burned by the stove and the harmful oil fume produced during the cooking process, and discharge it outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. [0003] Existing household range hoods are all driven by electricity, and the range hood needs to be manually turned on and off every time cooking, which consumes too much energy; in addition, the fan generates a lot of noise during use, which affects the user experience. Contents of the invention [0004] The object of the present invention is to propose a self-suction range hood in order to solve the shortcomings in th...
