Problems solved by technology

[0005] The pollutants trapped by this traditional high-voltage electrostatic degreasing device are accumulated on the plates in the channel. If the plates and high-voltage discharge corona wires are not cleaned regularly, the degreasing effect of the device will be greatly reduced and may even cause danger.
The problem lies in this, the structure of this high-voltage electrostatic degreasing device is relatively complicated, the cleaning and maintenance during use are very troublesome, and the installation and disassembly are also very inconvenient

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 , figure 2 , image 3 As shown, the electrostatic degreasing type range hood summarized in this embodiment includes a casing 1, a smoke collecting hood 2 arranged at the lower port of the casing 1, a fan 3 arranged in the casing, an anion generator 5, an anion channel 6 and a DC positive high voltage The generator 7 and the front port of the fume collecting hood 2 are provided with a rectifying plate 4 for guiding the smoke, and there is a gap between the rectifying plate 4 and the front end of the fume collecting hood 2 for the oil fume to enter. An oil cup (not shown in the figure) is provided at the inner lower end of the smoke collecting hood 2, and the oil cup can receive the oil dripping from the rectifying plate 4.

[0021] An anion generator 5 and an anion channel 6 are arranged in the fume collecting hood 2...

Abstract

The invention provides an electrostatic oil removal type range hood. The electrostatic oil removal type range hood comprises a shell (1), an exhaust fume collecting hood (2) arranged at a lower end opening of the shell (1) and a draught fan (3) arranged in the shell, wherein a commutation plate (4) for guiding fume is arranged at a front end opening of the exhaust fume collecting hood (2); a gap through which lampblack passes is formed between front end faces of the commutation plate (4) and the exhaust fume collecting hood (2); the electrostatic oil removal type range hood is characterized in that the exhaust fume collecting hood (2) is internally provided with a negative ion generator (5) and a negative ion channel (6); a transmitting end (51) of the negative ion generator (5) is located in the negative ion channel (6); an outlet of the negative ion channel (6) stretches out of the commutation plate (4); the shell (1) is internally provided with a direct-current positive high-voltage generator (7); and an output positive electrode of the direct-current positive high-voltage generator (7) is electrically connected with the commutation plate (4). The commutation plate has the effects of flow guide, oil collection and electrode plates and integrates various functions. The electrode plate does not need to be additionally arranged in the range hood, so that the whole structure is more compact and is very convenient to mount, dismount, wash and maintain.

Description

technical field [0001] The invention relates to a range hood, which belongs to the technical field of kitchen fume air purification. Background technique [0002] Regardless of whether it is a commercial kitchen or a family kitchen, the oily fumes produced during the cooking process and discharged through the range hood are a source of pollution for residents and the air environment. With the improvement of people's awareness of environmental protection, companies that manufacture range hoods are also paying more and more attention to the ability of range hoods to deal with oil fumes, and adopt various technical means to reduce pollutants in the exhausted range hoods. [0003] At present, the methods for dealing with oil fume in range hoods generally include: inertial collision interception method, centrifugal (or rotating) separation method, filtration method, and electrostatic method, among which the first three methods are more common. Although the electrostatic method w...
