The present invention proposes an electrostatic dust removal 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 present invention, referring to Fig. 1 to Fig. 4, the electrostatic precipitator module 1 includes:

The support 10, the opposite sides of the support 10 are respectively provided with an air inlet 710 and an air outlet 720, and the support 10 has an air flow channel 70 communicating with the air inlet 710 and the air outlet 720, the An electrostatic dust removal element is arranged in the airflow channel 70;

Negative ion generator 60 is arranged on the support 10 and is arranged near the air outlet 720; and

The conductive filter 50 is installed on the support 10 , and the conductive filter 50 covers the air inlet 710 , and the conductive filter 50 is connected with a positive voltage of a preset voltage.

Specifically, the electrostatic precipitator module 1 is arranged at the air inlet end of the indoor unit of the air conditioner, and the indoor air first passes through the airflow channel 70 of 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 airflow passage 70 is provided with an electric purification element. When the air passes through the airflow passage 70, the air is first ionized, and then the ionized particles in the air are adsorbed by the airflow passage 70, thereby realizing electrostatic dust removal, The purpose of air filtration and purification.

In order to improve the purification efficiency of the electrostatic precipitator module 1, in this embodiment, an anion generator 60 is provided at the air outlet 720 of the support 10, and a conductive filter 50 is provided at the air inlet 710 of the support 10, wherein the conductive The filter screen 50 covers the air inlet 710, and the conductive filter screen 50 is connected with a positive voltage. When the electrostatic precipitator module 1 was energized and worked, the negative ion generator 60 produced a large amount of negative ions near the air outlet 720, and the air outlet of the electrostatic precipitator module 1 was discharged from the air outlet 720, and then the air at the air outlet 720 was driven to make the air with negative ions Diffusion to various positions in the indoor environment, so that when the air with negative ions enters the air inlet 710 again through indoor air circulation, the conductive filter screen 50 has a positive charge, which can remove negatively charged particles, negative ions, etc. in the surrounding air. Filtering and adsorption are performed to realize preliminary filtering of the air before the air enters the airflow channel 70 from the air inlet 710 for electrostatic dust removal. Through the secondary purification and filtration of the air, the purification efficiency of the electrostatic precipitator module 1 is obviously improved.

When the indoor air has negative ions, the quality of the indoor air is significantly improved. Helps improve human immunity. At the same time, the negative ions in the room settle with the positively charged particles in the room, which can supplement and purify the air pollutants that are not fully purified by the electrostatic precipitator module 1, and further improve the indoor air quality. Of course, the above-mentioned conductive filter 50 can also preliminarily filter large particles in the air, and can also filter and adsorb volatile organic compounds, decoration odors and toxic gases in the air.

In this embodiment, the conductive filter 50 has conductivity and is connected with a positive voltage of a preset voltage value. In this way, when the negative ions in the air circulate through the filter 50 through the indoor air, since the filter 50 itself is positively charged, the charged particles in the air can be treated, adsorbed and filtered by electrostatic adsorption, so as to improve the purification effect. When the air passes through the positively charged filter screen 50, the filter screen 50 can ionize part of the particles in the air, and then when the air flows into the airflow channel 70, when the ionization electrode 30 ionizes the air, the particles in the air are more easily ionized Electrode 30 is ionized, and then the voltage of ionization electrode 30 can be reduced to reduce the probability of ozone generation while ensuring that the ionization effect of ionization electrode 30 remains unchanged.

It is worth noting that the airflow channel 70 in the electrostatic precipitator module 1 mainly adopts the dust removal method of electric purification, and an ionization device is usually arranged in the airflow channel 70. Since the ionization device has a high discharge voltage, while ionizing the surrounding air, It also produces ozone, which pollutes the environment. When the negative ion generator 60 is set at the air outlet 720 of the electrostatic precipitator module 1, there are still a large amount of negative ions in the indoor air. Ionization, and then can effectively reduce the voltage of the ionization device under the condition that the ionization effect remains unchanged. In this way, on the one hand, the probability of the ionization device generating ozone during the ionization process is reduced. The power consumption of the electrostatic precipitator module 1 is also reduced.

The technical scheme of the present invention is provided with a conductive filter 50 at the air inlet 710 of the electrostatic precipitator module 10, and an anion generator 60 is arranged at the air outlet 720. The anion generator 60 makes the indoor air have negative ions, and after the indoor air circulates through the indoor air, When entering the air inlet 710 again, the conductive filter 50 adsorbs negatively charged particles and negative ions in the air, so that before the air enters the airflow channel 70 for electrostatic dust removal, the air is initially filtered and purified, thereby realizing the protection of the air. Multi-stage filtration significantly improves the air purification efficiency.

Further, the electrostatic precipitating element of the air channel 70 can be arranged in a variety of ways. In this embodiment, the electrostatic precipitating element preferably adopts the following structure: the electrostatic precipitating element includes a plurality of dust removing units, any of which includes: an ionizing electrode 30 And the repelling pole 40 is all located in the airflow passage 70, and is arranged in sequence along the airflow direction of the airflow passage 70; and the same side of the repeller 40.

It can be understood that the dust collecting pole 20 is connected with a voltage of a predetermined voltage value, the ionizing pole 30 is connected with a high voltage opposite to the voltage of the dust collecting pole 20, and the repelling pole 40 is connected with a voltage opposite to the voltage of the dust collecting pole 20, In this way, in the airflow channel 70, the ionization electrode 30 and the dust collection electrode 20 form an ionization channel 730, and the repelling electrode 40 and the dust collection electrode 20 form a dust collection channel 740. When air enters the airflow channel 70 from the air inlet 710, the ionization electrode 30 The particles in the air are ionized by its own high-voltage electric field, and the air mixed with the ionized particles then enters the dust collection channel 740. Under the action of the bias electric field formed by the repeller 40 and the dust collection electrode 20, the ionized particles flow toward The surface of the dust collecting pole 20 on the side is biased, and then is adsorbed on the surface of the dust collecting pole 20 to realize the whole dust removal process.

It should be noted that, for the dust collecting pole 20, the air flow passage 70 formed by it is divided into two parts, namely the ionization passage 730 connected with the air inlet 710 and the dust collection passage 740 connected with the air outlet 720, wherein the dust collection The pole 20 includes an exciting part 210 facing the ionizing pole 30, and a collecting part 220 facing the repelling pole 40, wherein the ionizing pole 40 and the exciting part 210 form an ionization channel 730, and the repelling pole 40 and the collecting part 220 are arranged in parallel , the repeller 40 and the collecting part 220 form a dust collection channel 740 . It should be noted that since the exciter 210 and the repelling pole 220 in the dust collecting pole 20 are integrated, the ionization channel 730 and the dust collecting channel 740 are integrated and seamlessly connected, so that better purification efficiency can be maintained. On the premise of the same, the length of the airflow channel 70 is also reduced, thereby reducing the volume of the support 10 and the electrostatic precipitator module 1 , so that the electrostatic precipitator module 1 has the advantage of lightness and compactness.

On the one hand, it also avoids arranging a fixed structure on the conductive filter 50 and causing damage to the structure of the conductive filter 50 itself, improves the height of the conductive filter 50 itself, and prolongs the service life of the conductive filter 50 .

Wherein, the negative ion generator 60 is generally installed and fixed on the frame bar of the support 10, that is, at the edge of the second frame surface 120. 120 connection, the frame bars of the second mounting frame 90 are provided with holes or openings to avoid the negative ion generator 60, so that when the negative ion generator 60 is located in the above-mentioned holes or openings, the second mounting frame 90 is opposite to the negative ion generator 60. It can play a certain protective role to prevent the negative ion generator 60 from being damaged by external force, so as to ensure and improve its working reliability.

The conductive filter 50 is preferably made of a porous conductive material, and the contact area between air particles and the conductive filter 50 is increased through the porous material.
