range hood

Abstract

The invention discloses an electrostatic device and a kitchen ventilator. The electrostatic device (2) comprises a discharging module assembly and tubular polar plate assemblies. The tubular polar plate assemblies comprise the first tubular polar plate assembly and the second tubular polar plate assembly which are opposite in polarity. The first tubular polar plate assembly comprises a plurality of first tubular polar plates arranged in a concentric mode and nested at intervals in the radial direction. The second tubular polar plate assembly comprises a plurality of second tubular polar platesarranged in a concentric mode and nested at intervals in the radial direction. In the axial direction of the tubular polar plate assemblies, the first axial end of the first tubular polar plate assembly and the first axial end of the second tubular polar plate assembly are aligned, the second axial end of the second tubular polar plate assembly is shorter than the second axial end of the first tubular polar plate assembly, the discharging module assembly of the same polarity as the second tubular polar plate assembly is installed at the second axial end of the first tubular polar plate assembly, and a discharging electrode extends to the position between the adjacent first tubular polar plates. The electrostatic device has the advantages of being compact in structure, convenient to assemble and disassemble and good in fume purification effect.

Description

technical field [0001] The invention relates to the field of household kitchen appliances, in particular to an electrostatic device and a range hood. Background technique [0002] With the increasing awareness of environmental protection, air pollution has become a hot topic among people. During the cooking process, a large amount of harmful substances are produced along with the burning of oil fume and fuel. Some traditional range hoods directly exhaust the oil fume to the outside, causing the oil fume to directly enter the atmosphere and cause air pollution, which affects people's health. [0003] In view of the above-mentioned problem of oil fume polluting the atmosphere, more and more range hoods are currently using electrostatic oil filtering methods to purify the oil fume. In the existing electrostatic devices, electrode plates are usually used for electrode plates or electrode plates for needle plates. The form of this type of range hood has a high degree of grease ...

AI Technical Summary

Problems solved by technology

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. Therefore, it needs to be disassembled and cleaned after pollution to restore the good performance of the electrostatic device to absorb oil fume.

Usually, the electrostatic device is installed inside the range hood, and when disassembling the electrostatic device, it is necessary to disassemble the housing of the frame assembly of the range hood. The electrostatic device is inconvenient to disassemble and clean, and it is difficult to achieve the effect of circulating oil filtration
