Electrostatic devices and range hoods

Abstract

The invention discloses an electrostatic device and a kitchen ventilator. The electrostatic device (4) comprises a collecting needle electrode module (1), a honeycomb electrode module (2) and an ionizing needle electrode module (3) which are stacked in sequence. According to the electrostatic device, three module structures of the collecting needle electrode module, the honeycomb electrode module and the ionizing needle electrode module which are stacked and interpenetrated in sequence are included, compared with a common electrostatic device with opposite plate electrodes, the composition structure is more simplified and compact and saves more space, and the convenience of production, manufacture and assembly are enhanced. The electrostatic device is of a honeycomb type structure, the collecting needle electrode module and the ionizing needle electrode module use a honeycomb electrode module in common, and a plurality of collecting needle electrodes and a plurality of electro-discharging needle electrodes are respectively inserted into a plurality of honeycomb column holes from the two sides in a one to one correspondence mode; and the honeycomb type structure enables an electric field of the electrostatic device to be more even and stable, so electriferous oil fume particles are captured and collected more easily, and therefore, a better oil fume collecting and cleaning effect is achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electrostatic device and a range hood. Background technique [0002] At present, it is common to use electrostatic oil filtering for range hoods on the market, and the oil separation degree of range hoods is relatively high. However, due to long-term use, a large amount of grease will accumulate inside the range hood, especially in the fan and pipeline, thereby reducing the performance and smoking effect of the range hood and increasing the noise of the range hood. The method of removing the oil fume in the range hood by absorbing the oil fume with an electrostatic device has gained certain approval in terms of application. [0003] Currently commonly used electrostatic devices include plate-plate type, needle-plate type, and even honeycomb structure. However, the structure of the needle pole and electrode plate of these electrostatic devices is relatively complicated, and...

Problems solved by technology

[0003] Currently commonly used electrostatic devices include plate-plate type, needle-plate type, and even honeycomb structure. However, the structure of the needle pole and electrode plate of these electrostatic devices is relatively complicated, and the overall structure of the electrostatic device is huge, there are many parts, and installation is time-consuming. Many problems, and the effect of oil fume collection and purification is not good, there is still a lot of room for improvement
