Electrostatic purification device and range hood provided with same

Abstract

The invention provides an electrostatic purification device. The device comprises an outer frame, positive plates, negative plates, an electrode wire, a positive wire, a negative wire, and a polar plate connecting frame, wherein the polar plate connecting frame is arranged inside the outer frame and divides the interior of the outer frame into an upper-layer space and a lower-layer space; and thenegative plates comprise the first negative plates and the second negative plates, the first negative plates and the second negative plates are connected to the polar plate connecting frame, the firstnegative plates and the electrode wire are distributed in the lower-layer space at intervals to form a charged region, the electrode wire communicates with the positive plates, and the second negative plates and the positive plates are distributed in the upper-layer space at intervals to form a dust collecting region. The invention further discloses a range hood provided with the electrostatic purification device. The electrostatic purification device is divided into the dust collecting region and the charged region through the polar plate connecting frame, so that the electrostatic purification device is simple in mounting structure and convenient to assemble; and in addition, after the electrostatic purification device is arranged at the front end of a fan system, the emission of oil smoke can be reduced, the oil smoke can be effectively purified before entering the fan system, so that fan impellers can be kept clean for a long time, and after-sale maintenance is convenient.

Description

Technical field [0001] The invention relates to a range hood, in particular to an electrostatic purification device and a range hood equipped with the device. Background technique [0002] At present, in order to prevent oil fume from polluting the environment, people usually install special oil fume purification devices on the flue to eliminate oil fume pollutants. Existing oil fume purification devices have a variety of structures, such as filter membrane type, water curtain type, centrifugal type and so on. Among them, although the filter membrane type purification device can effectively remove oil fume, it is easy to be blocked and must be replaced frequently, which is more troublesome to use. The water curtain type purification device uses water to remove oil fume, which not only easily causes secondary pollution, but also wastes a large amount of water, which is costly. The centrifugal purification device not only produces a lot of noise when working, but also has a relat...

AI Technical Summary

Problems solved by technology

Although the electrostatic purification device has the advantages of low energy consumption, low noise, and no secondary pollution, it adopts a simple positive and negative plate staggered structure, the positive and negative plates are not staggered from each other, and the positive and negative plates are installed on the On the same support frame, when oil stains are accumulated on the support frame, the surface is prone to creepage, and the current discharges on the surface, resulting in the reduction of moving charged particles between the plates, so that the positive and negative plates are easily conducted, and then the electrostatic purification device fail

[0004] In addition, in order to purify the oil fume in the oil fume passage, the prior art has disclosed a range hood in which an electrostatic purification device is installed in the oil suction passage. However, the existing electrostatic purification devices are all installed at the rear end of the fan system , although it can also effectively purify the oil fume, but because it is located at the rear end of the fan system, the oil fume cannot be purified before it enters the fan system, so it cannot clean the impeller, and cannot keep the inside of the hood clean and prolong the cleaning of the range hood maintenance time requirements
