Extractor hood

Abstract

The invention discloses an extractor hood. An electrostatic device (4) and a cleaning device (3) are arranged in a rack assembly (1) of the extractor hood; the cleaning device comprises a spray head assembly (39) used for spraying and cleaning the electrostatic device and a reciprocating driving mechanism (30) used for driving the spray head assembly to do reciprocating motion; and an oil-proof box (5) is arranged in the extractor hood, and a spray head (395) of the spray head assembly (39) is stored in the oil-proof box at the start position and the final position of the reciprocating motion.According to the extractor hood, the cleaning device capable of achieving automatic cleaning is additionally arranged, and therefore the electrostatic device can be conveniently sprayed and cleaned in time; and when the extractor hood is in the working condition of oil fume extraction, the interior of a cavity is an environment filled with oil fume, the spray head of the spray head assembly of the cleaning device has the function of being capable of resetting into the oil-proof box in time after completing cleaning work, therefore, oil fume environment pollution is avoided, the spray head cannot be plugged, then the using performance of the cleaning device is guaranteed, and the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the field of household kitchen appliances, in particular to a range hood. Background technique [0002] In view of the existing problem of oil fume polluting the atmosphere, more and more range hoods are currently purifying the oil fume by using electrostatic oil filtration. The oil fume method has gained certain approval in terms of application. However, due to long-term use, the electrostatic device of the range hood will accumulate a large amount of grease, which will reduce the performance and smoking effect of the electrostatic device. In addition, the accumulation of grease can easily cause the creepage of the two-pole circuit and cause a short circuit. Therefore, it needs to be disassembled and cleaned regularly after pollution to restore the good oil fume adsorption performance of the electrostatic device. [0003] Since the electrostatic device is often installed inside the range hood, the disassembly steps of the el...

AI Technical Summary

Problems solved by technology

[0003] Since the electrostatic device is often installed inside the range hood, the disassembly steps of the electrostatic device are cumbersome and the workload is heavy, resulting in inconvenient operation

In addition, in some existing range hoods, the method of installing a heating wire in the electrostatic device is used to remove the lampblack covered by the electrostatic device, but this method is not ideal. Not only is there a problem that the installation of the heating wire is difficult, but the removal effect is not obvious
