The utility model proposes an electrostatic dedusting module, which ionizes particles in the air by means of electrostatic dust removal through electric purification technology, and then collects the ionized particles through a bias electric field to achieve the purpose of purifying the air. It can be understood that the electrostatic precipitator module can be applied to air-conditioning devices such as air purifiers and air conditioners, and can also exist alone as a purification device. The following takes the air conditioning device as an air conditioner as an example to make a specific explanation of the electrostatic precipitator module.

In an embodiment of the utility model, referring to Fig. 1 to Fig. 4, the electrostatic dust removal module 1 includes a plurality of dust removal units, and any of the dust removal units includes:

The ionization electrode 40 and the repelling electrode 30 arranged in sequence along the wind inlet direction;

The dust collecting electrode 20 is arranged on the same side of the ionizing electrode 40 and the repelling electrode 30 , and at least part of the dust collecting electrode 20 is bent.

Specifically, the electrostatic dust removal module 1 is arranged at the air inlet end of the indoor unit of the air conditioner, and uses the principle of electrostatic dust removal to collect and filter particulate pollutants in the air entering the housing of the indoor unit. The indoor air first passes through the electrostatic precipitator module 1 for dust removal operation, and then flows into the heat exchange system of the indoor unit. For the electrostatic precipitator module 1, the dust-collecting pole 20 is connected with a voltage of a preset voltage value, the ionization pole 40 is connected with a high voltage opposite to the voltage of the dust-collecting pole 20, and the repelling pole 30 is connected with the voltage of the dust-collecting pole 20. Opposite voltage, like this, ionization pole 40 forms ionization channel 510 with dust collection pole 20, repels pole 30 and dust collection pole 20 and is arranged in parallel, and repels pole 30 and dust collection pole 20 to form dust collection channel 520, and the ionization channel 510 The air outlet end communicates with the air inlet end of the dust collection channel 520 . At this time, the ionization channel 510 and the dust collection channel 520 jointly form the air flow channel 50 of the electrostatic precipitator 1 . The airflow channel 50 has an air outlet 50b and an air inlet 50a. When the air enters the airflow channel 50 from the air inlet 50a, the ionization electrode 40 ionizes the particles in the air through its own high-voltage electric field, and the air mixed with the ionized particles then enters the dust collector. In the channel 520, under the action of the bias electric field formed by the repelling electrode 30 and the dust collecting electrode 20, the ionized particles are biased toward the surface of the dust collecting electrode 20, and then are adsorbed on the surface of the dust collecting electrode 20, so as to realize the whole Dust removal process.

Referring to Fig. 4, the dust collecting pole 20 comprises an exciting part 230 facing the ionizing pole 40, and a collecting part 240 facing the repelling pole 30, wherein the ionizing pole 40 and the exciting part 230 form an ionization channel 510, and the repelling pole 30 and the The collecting part 240 is arranged in parallel, and the repelling electrode 30 and the collecting part 240 form a dust collecting channel 520 .

However, while the electrostatic precipitator module 1 is miniaturized, the length of the airflow channel 50 of the electrostatic precipitator module 1 is reduced, and the dust collection area of the dust collecting pole 20 (the area of the part of the surface of the dust collecting pole 20 facing the repelling pole 30) is also reduced. As a result, the probability of particles in the air being adsorbed and collected by the dust collecting pole 20 is reduced, which in turn leads to a serious decline in the purification effect of the entire electrostatic precipitator module 1 . In order to solve the above problems, in this embodiment, at least part of the dust collecting pole 20 is bent. At this time, the length and specific surface area of the dust collecting pole 20 are also effectively increased compared with the flat common pole piece. In this way, under the condition that the overall volume of the electrostatic precipitator module 1 remains unchanged, the length of the airflow channel 50 or the surface area of the inner wall can be effectively increased to realize the increase of the dust collection area of the dust collection pole 20 and increase the collection of particulate matter in the air.

When the air passes through the ionization channel 510, the air particles entrained in it are ionized. When the air passes through the dust collection channel 520, the ionized air particles are collected by the dust collecting electrode 20 Adsorption and collection, because at least part of the dust collecting pole 20 is bent, the length or specific surface area of the dust collecting pole 20 is effectively increased. At this time, the length or The surface area of the inner wall increases, and the purification treatment time of the air in the airflow channel 50 is effectively extended, and at the same time, the dust collection area of the dust collection pole 20 is also increased, so that the particles in the air are adsorbed and collected on the dust collection surface of the dust collection pole 20 The probability of the electrostatic precipitator is greatly improved, and then the purification efficiency of the electrostatic precipitator module 1 is improved without increasing the external volume of the electrostatic precipitator module 1 .
