Electrostatic cooking fume purification device and range hood with same

Abstract

The invention relates to an electrostatic cooking fume purification device and a range hood with the same. The electrostatic cooking fume purification device comprises a shell, a dust collection electrode, an ionization electrode and an adjusting structure. The dust collection electrode comprises at least two dust collection plates which are parallelly arranged at intervals; the ionization electrode comprises polar plates and polar filaments, closed frames are formed by the polar plates, and at least two of the polar filaments are arranged in each frame at intervals; each polar plate is arranged between the two corresponding adjacent dust collection plates, and the distances from the polar plates to the adjacent dust collection plates are equal to one another; the distances between the adjacent dust collection plates can be adjusted by the adjusting structure. The electrostatic cooking fume purification device and the range hood has the advantages that the distances between the dust collection plates can be reduced by the adjusting structure when cooking fume is high in concentration, accordingly, the field intensity at identical voltages can be increased, and the cooking fume particle adsorption capacity can be improved; the distances between the dust collection plates can be increased when the cooking fume is low in concentration, accordingly, the field intensity at the identical voltages can be reduced, energy can be saved, and the service cost can be lowered.

Description

technical field [0001] The invention relates to an electrostatic oil fume purification device and a range hood applied with the device. Background technique [0002] In order to reduce the pollution of oil fume to the indoor and outdoor environment, and reduce the rejection of catering enterprises by the public, especially the public around the area, it is necessary to use oil fume purification devices. The oil fume purification devices commonly used in the prior art include: mechanical oil fume purification devices, water mist spray Shower type oil fume purification device and electrostatic oil fume purification device. [0003] Among them, the working principle of the electrostatic oil fume purification device is: use a high-voltage electrostatic field to ionize the gas passing through the electrodes, and then adsorb it on the electrodes to achieve the purpose of purifying the oil fume. Commonly used electrostatic devices are divided into two types: the modular design of ...

Problems solved by technology

[0004] In the above-mentioned existing electrostatic oil fume purification device, when the oil fume flow rate of the range hood changes, the electric field strength can only be changed by changing the voltage of the dust collecting electrode to adapt to the change in flow rate, thereby improving the efficiency of electrostatic oil fume removal, and changing The voltage of the dust collector requires a high-cost power supply circuit board, resulting in high cost of use; and the general power supply can only realize step-by-step voltage regulation, which will cause energy waste to a certain extent and affect the purification effect
