Range hood self-cleaning device

Abstract

The invention discloses a self-cleaning device of a range hood. The device comprises a heating device which is positioned in a shell of the range hood, and is characterized in that the heating device is positioned at the outer side of a volute of the range hood; an internal recycle channel is formed between the heating device and the volute of the range hood; and the internal recycle channel and a smoke discharge channel of the range hood are separated mutually and are not smooth simultaneously. The self-cleaning device of the range hood provided by the invention not only has a simple structure and low cost, but also the heating device is far away from the volute, the device can be heated efficiently and rapidly, and the cleaning time is shorter; the volute and an impellor can be heated together through the internal recycle wind in the range hood, the self-cleaning effect is improved, and the self-cleaning time is improved; and only when the heating device is cleaned, greasy dirt passes, the accumulation of the greasy dirty on the surface of the heating device is prevented, the safety problem of greasy dirt ignition caused by the overheating of the heating device is prevented, and the safety performance of the self-cleaning device is improved.

Description

technical field [0001] The invention relates to a cleaning device for a range hood, in particular to a self-cleaning device inside the range hood. Background technique [0002] With the advancement of science and technology and the improvement of living standards, various household appliances have become popular rapidly, and range hoods have long become an indispensable appliance in the kitchen. When the range hood sucks the indoor fume gas, a large amount of grease and oil will be adsorbed on the surface of the range hood's impeller and volute. If these greases and oils are not cleaned for a long time, they will be oxidized and air-dried and difficult to clean, and the accumulation of too much grease and oils on the impeller will increase the load, increase the noise, and reduce the effect of oil suction. Therefore, it is necessary to clean the inside of the range hood. The traditional cleaning method is to disassemble the range hood and clean it manually with water or de...

Problems solved by technology

However, this cleaning device requires components such as sprinklers, pumps, and cleaning fluids, which not only has high cost, complex structure, and is prone to various coordination problems that affect performance

Moreover, the cleaning fluid in the container needs to be preheated, which results in long preheating time and a long time for the entire cleaning process. If the heated cleaning fluid is not used up, a large amount of heat energy will be wasted, and the delivery channel of the cleaning fluid will also be shortened. If it is too long, more heat will be emitted during the transportation process, and the temperature will drop significantly, which will affect the cleaning effect
