Fan cleaning device and range hood applying same

Abstract

The invention discloses a fan cleaning device and a range hood applying the same. The fan cleaning device comprises a fan system and a cleaning mechanism for cleaning the fan system; the fan system comprises an impeller; the cleaning mechanism comprises a cleaning arm and a cleaning medium supply module for providing a cleaning medium for the cleaning arm; the fan cleaning device is characterized in that the cleaning arm comprises main arms; the main arms are located on the periphery of the impeller and at least corresponds to the part between the two axial ends of the impeller; first spraying holes used for spraying a cleaning medium to the impeller are formed in the main arms; and the main arms can rotate around the periphery of the impeller. Compared with the prior art, the fan cleaning device has the advantages that the main arms of the cleaning arm of the cleaning mechanism is arranged on the periphery of the impeller and can rotate around the periphery of the impeller, so that the whole surface of the impeller can be completely covered; the limitation of an air inlet mode of the fan system is eliminated; and the impeller can be comprehensively cleaned.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a fan cleaning device and a range hood using the fan cleaning device. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Due to the particularity of the kitchen environment, as the range hood is used for a long time, a large amo...

Problems solved by technology

[0007] In this self-cleaning method of the volute, hot melt has a greater effect on the melting of the volute, but the oil on the surface can only be left by gravity to overcome the viscosity, and the effect is not good. For the oil on the impeller, the distance is relatively long, and the middle Separated, the heat can only be transferred through the heat radiation impeller of the volute wall, the heat transfer efficiency is low, and the hot melting effect is poor. Even with the centrifugal force of high-speed oil throwing, the effect is not obvious
