Range hood with static lampblack purification plant

Abstract

The invention discloses a range hood with a static lampblack purification plant. The range hood comprises a centrifugal fan, the static lampblack purification plant positioned above the centrifugal fan, and an air outlet housing positioned between the centrifugal fan and the static lampblack purification plant, wherein the static lampblack purification plant comprises an ionization module and a dust collecting module, the dust collecting module comprises multiple dust collecting plates which are arranged at intervals, and the polarities of the two adjacent dust collecting plates are different; the air outlet of the centrifugal fan is positioned below one ends of the dust collecting plates, and the lower edges of the dust collecting plates gradually incline upward so as to form a corner cut from one end positioned above the air outlet of the centrifugal fan to the other end which is far away from the upper side of the air outlet of the centrifugal fan. The lower edges of the dust collecting plates form one corner cut, after being accumulated to a certain extent, oil drops flow automatically, so that a vane wheel of the centrifugal fan is prevented from being polluted, the oil drop is positioned on the location which is far from the air outlet of the centrifugal fan, the ventilated area at the part, which is far away from the air outlet of the centrifugal fan, is increased, and thus the air volume and the wind pressure are further improved.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with an electrostatic oil fume purification 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 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 to use a high-voltage electrostatic field to ionize the gas passing through the electrodes, thereby adsorbing 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...

AI Technical Summary

Problems solved by technology

When this kind of electrostatic field purification device is used in the range hood, it is generally placed on the fan. The problem is that when the electrostatic field purification device works for a long time, a lot of oil will be absorbed on the collection area (dust collection plate) , oil pollution accumulated to a certain extent, it will drip down, and the pollution of the fan will be more serious; and the electrostatic field purification device will increase the wind resistance and reduce the air volume, weakening the suction of the range hood
