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 foaming seat, a first liquid guide pipe, a driving part, a second liquid guide pipe, a gas guide pipe and a third liquid guide pipe, wherein the foaming seat is provided with a mixing chamber; the first liquid guide pipe is provided with a first end opening allowing water to be input, and a second end opening of the first liquid guide pipe communicates with the mixing cavity of the foaming seat; the second liquid guide pipe is provided with a first end opening allowing a detergent toinput, a second end opening of the second liquid guide pipe communicates with the mixing cavity of the foaming seat, and the gas guide pipe communicates with the mixing cavity; and a first end opening of the third liquid guide pipe is connected with an output opening of the mixing cavity, and a second end opening of the third liquid guide pipe extends into the fan. A water flow is sprayed into the mixing cavity of the foaming seat through the first liquid guide pipe, meanwhile, the detergent enters the mixing cavity through the second liquid guide pipe and air enters the mixing cavity throughthe third liquid guide pipe to be mixed with the water flow to form a cleaning medium with foam, the foam can prolong the contact time between the foam and the inner surface of the fan and can emulsify oil contamination, so that the cleaning effect is improved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with self-cleaning function. Background technique [0002] During the use of the range hood, a large amount of oil will accumulate on the impeller and the filter, which will easily cause blockage, increase the load, etc., and affect the use effect of the range hood. With the continuous advancement of range hood self-cleaning technology, steam cleaning has been widely used in the self-cleaning field of range hoods. The basic principle of steam cleaning is to generate steam from a steam generator, and then deliver the steam to the nozzle at the end of the spray pipe. The steam is quickly ejected from the nozzle to wash the impeller and the volute for cleaning. [0003] For example, the Chinese invention patent application "hood cleaning assembly and hood" (application number: 201610563284.4) with the application publication number of CN 106180036 A discloses a structure in ...

Problems solved by technology

[0004] The above-mentioned structure can realize the function of cleaning the range hood, but it can only clean the range hood with a single medium, and the contact time between water and the solution of the cleaning medium added to the surface to be cleaned is extremely short, and the cleaning effect is poor. , and if the cleaning time is prolonged, the cleaning cost will increase
