Cleaning device for range hood, fan cleaning device and range hood

Abstract

The invention discloses a cleaning device for a range hood, the cleaning device comprises a cleaning medium supply piece (3), the cleaning medium supply piece (3) comprises a moving part and an outlet (302) which is arranged on the moving part and is used for ejecting a cleaning medium, and the cleaning device is characterized in that the moving part is arc-shaped; the cleaning device further comprises a driving device (4), the power output end of the driving device is in transmission connection with the moving part, and the driving device is used for driving the whole moving part to swing. The invention further discloses a fan cleaning device applying the cleaning device and an extractor hood. Compared with the prior art, the cleaning device is small in occupied space and wide in cleaning range.

Description

technical field [0001] The invention relates to the technical field of kitchen equipment, in particular to a cleaning device for a range hood, a blower cleaning device and a range hood. Background technique [0002] With the continuous improvement of range hood self-cleaning technology, steam cleaning or water cleaning has been widely used in the self-cleaning field of range hoods. The basic principle is to generate steam by a steam generator or pump water to transport steam or water To the nozzle at the end of the spray pipe, steam or water is sprayed quickly from the nozzle to wash the impeller and volute for cleaning. [0003] At present, there are generally fixed holes on the spray pipe, and the number of holes is generally more than 3, but this cleaning method has the following disadvantages: First, when cleaning, steam or water is sprayed from the fixed nozzles, because there are limited Nozzles, so the flushing force at the interval between the nozzles is very weak, ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are generally fixed holes on the spray pipe, and the number of holes is generally more than 3, but this cleaning method has the following disadvantages: First, when cleaning, steam or water is sprayed from the fixed nozzles, because there are limited Nozzles, so the flushing force at the interval between the nozzles is very weak, and the cleaning effect is not good; second, due to the large number of holes, the power of the steam generator or pump is constant, so the steam pressure or water pressure coming out of the nozzles is low. Correspondingly low and unstable, resulting in poor cleaning effect

[0005] However, first, for the above-mentioned first solution, it is necessary to set a long strip-shaped relief hole extending along the moving direction of the cleaning medium supply part on the volute, which will greatly modify the original structure of the fan, which will easily affect the performance of the fan. If the shielding part is set, there will be a problem that the viscous grease will stick to the shielding part after a long time, so that it cannot be opened or closed tightly; secondly, for the above-mentioned second scheme, the horizontal feeding type cleaning medium supply part requires an occupation of There is a lot of space, and the size of the current existing products is difficult to support such a large space; third, for the impeller, the oil stains in some parts are relatively stubborn, and often the oil stains in other positions cannot be completely removed. However, if the cleaning time is increased, it will cause a great waste of power consumption.
