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 guiding pipe, a second liquid guiding pipe, a third liquidguiding pipe and a driving part, the interior of the foaming seat is hollow to form a mixing cavity, the first liquid guiding pipe is provided with a first port for allowing water to be input, a second port of the first liquid guiding pipe communicates with the mixing cavity of the foaming seat, the second liquid guiding pipe is provided with a first port for allowing a detergent to be input, a second port of the second liquid guiding pipe communicates with the mixing cavity of the foaming seat, a first port of the third liquid guiding pipe is connected with an output port of the mixing cavity, and a second port of the third liquid guiding pipe extends into the fan. A water flow is sprayed into the mixing cavity of the foaming seat through the first liquid guiding pipe and is atomized to acertain extent to generate a negative pressure in the mixing cavity, the detergent is sucked into the mixing cavity through the second liquid guiding pipe to be mixed with the water flow to form a cleaning medium with foam, the contact time with the inner surface of the fan can be prolonged through the foam, the foam emulsifies oil contamination, and thus 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 ...

AI Technical Summary

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
