Kitchen range hood

Abstract

The invention relates to the technical field of household appliances, and discloses a kitchen range hood. The kitchen range hood comprises a machine shell, an air duct shell, an air collection cover and a draught fan. The air duct shell is fixedly connected into an inner cavity of the machine shell in a sleeved mode, the air collection cover is fixedly connected to one ends of the machine shell and the air duct shell, the draught fan is located in the machine shell and an air opening of the draught fan communicates with the inner cavity of the air duct shell, a mesh enclosure is arranged in the inner cavity of the air duct shell, and an impeller is connected to the bottom surface of the mesh enclosure through a connecting rod. According to the kitchen range hood, the impeller and a permanent magnet on the impeller are driven to rotate through the flowing of lampblack, so that the changing of the coil magnetic flux is caused, a current is generated in a coil, and the current is stored in a storage battery for use; and meanwhile, a magnetic patch in a scraping stripe rotates under the action of magnetic field force of the permanent magnet, so that the purpose of scraping oil dirt onthe air duct shell and the mesh enclosure is achieved, the cleanness degree of the interior of the range hood is improved, and the disassembly and cleaning frequency of the range hood is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a kitchen range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. The range hood can purify the harmful oil fumes generated during the cooking process and provide protection for people's physical safety. Therefore, the range hood is more and more widely used. [0003] The range hood is mainly composed of an organic shell, air duct, fan, check valve, oil collection and discharge device, lighting device, power switch and power cord. The fan rotates to form a negative pressure area, and the air outside the range hood is under negative pressure. Under the action, it flows to the inside of the range hood, and separates the oil fume inside the range hood, so as to achieve the purpose of purifying the air. [0004] At present, in order to protect the fan and separate the oil fume, the existing range hoods will ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the use of the existing range hoods proposed in the background technology, the present invention provides a kitchen range hood, which can slow down the temperature rise of the grille, improve the condensation effect of the grille on the oil fume, and at the same time can Reduce the grease on the screen cover, ensure the flow of harmless smoke, effectively reduce the flow velocity of the air carrying the oil fume at the screen cover, improve the oil fume separation performance of the screen cover, and solve the temperature problem of the screen cover proposed in the above background technology The problem that the condensing effect on the oil droplets is reduced due to the increase, the oil dirt clogs the holes of the mesh cover hinders the flow of the flue gas, and the oil fume separation performance of the mesh cover is reduced due to the excessive flow velocity of the oil fume at the mesh cover
