Range hood with self-cleaning function

Abstract

The invention relates to a range hood with a self-cleaning function. The range hood comprises a shell, a fan, a cleaning medium supply mechanism, a spray pipe, a power mechanism and an air blowing mechanism, wherein a filter screen is arranged at an air inlet of the fan, the water outlet end of the cleaning medium supply mechanism is connected with the first end of the spray pipe, the second end of the spray pipe corresponds to the front side surface of the filter screen, the power mechanism is arranged on the fan and can drive the filter screen to rotate independently of an impeller, the blowing mechanism is used for blowing cleaning medium in a volute, and an opening communicating with an air outlet of the blowing mechanism is formed in the bottom of the volute. Under the oil fume suction state of the range hood, the fan drives the impeller to rotate, and at the moment, the power mechanism does not operate, and the filter screen is in a static state; when the range hood needs to be cleaned, the fan drives the impeller to rotate, and meanwhile, the power mechanism drives the filter screen to rotate; and at the moment, the spray pipe discharges water to wash the filter screen, theimpeller and the volute, so that oil contamination is prevented from accumulating, the self-cleaning effect is achieved, and thus the range hood can keep a good oil removal function.

Description

technical field [0001] The invention relates to a range hood with self-cleaning function. Background technique [0002] In recent years, people's living standards have been continuously improved, and people's awareness of health and environmental protection has been increasing. People are eager to have a healthy, clean and environmentally friendly home kitchen environment. Chinese patent CN200710051289 discloses an air dust centrifugal purification device and a method for manufacturing the rotating filter disk. The rotating filter disk is composed of a mesh disk skeleton and a radially radial filter mesh uniformly wound around the periphery. The above-mentioned filter disc is made of a filter wire wound, the production method is complicated, the filter wire is easily corroded and broken, and the filter wires are densely interlaced in the middle area of ​​the net disc, resulting in large oil fume wind resistance and poor flow of oil fume to block the filter screen , so that ...

AI Technical Summary

Problems solved by technology

[0004] The above two structures can achieve oil fume purification to a certain extent, but during use, the grease adhering to it is naturally removed by centrifugation, and stubborn grease will inevitably adhere to it after long-term use , thereby affecting its filtration performance
