The indoor unit of the central air conditioner is generally installed in the ceiling. For the user, the installation position is high, and it is usually difficult for the user to clean it in time. As a result, some dust and impurities will accumulate on the surface of the coil of the indoor heat exchanger, which will affect both. The heat exchange efficiency of the indoor heat exchanger is easy to breed bacteria on the surface of the filter screen and the indoor heat exchanger, causing the air conditioner to produce odor, affecting the air quality of the indoor environment, and even affecting the health of users. During the operation of the air conditioner, the bacteria will have a secondary impact on the user's health after being blown out by the air deflector.

At this time, even if the main box body 2 does not move up and down, it can also cooperate with the shaking device 3 to achieve static electricity protection. Automatic cleaning of dust collection module 1. In addition, since a primary filter structure is usually provided at the air return port of the air conditioner, the main box 2 may be provided with a lift-type structure 7 or not along the side away from the indoor heat exchanger.

Example 2

This embodiment is one of the optimizations made on the structural layout of the shaking device 3 on the basis of the first embodiment.

As shown in FIGS. 3-4 , as one of the preferred embodiments of the present invention, on the lower housing 11 of the electrostatic precipitator module 1 , the first slots 111 and the first filter holes 112 are arranged in parallel and staggered.

Specifically, the high voltage electrode plate 201 in the dust collection area and the ground electrode plate 202 in the dust collection area are arranged at intervals of a second different pole distance, and can be inserted into the first slot 111; furthermore, at least in the dust collection area ground electrode plate On both sides of the 202, the first filter holes 112 will be distributed.

Preferably, the electrostatic dust collection module 1 is suspended and connected to the main box body 2 through a tension spring 8, and/or is clamped on a support frame 22, wherein the support frame 22 is arranged on the main box body 2 inside.

Specifically, the electrostatic precipitator module 1 can have various setting forms in the main box 2, and more detailed and optimized settings can be made according to the structural layout of the shaking device 3 and the collection method after the dust is shaken. In this embodiment, the tension spring 8 can suspend the electrostatic precipitator module 1 and the inner wall surface of the main box 2 in the horizontal direction; and the support frame 22 only needs to form a clamping arrangement for the electrostatic precipitator module 1 . No matter which setting form is adopted, the lower casing 11 will be suspended and exposed above the dust collecting funnel 5, which is conducive to blowing the dust after shaking to the dust collecting funnel 5 through the first filter hole 112.

Specifically, the electrostatic precipitator module 1 may have various arrangement forms in the main casing 2, and the lower casing 11 is not necessarily provided with the first filter holes 112. After being shaken by the shaking device 3, the dust adsorbed on the grounding plate 202 in the dust collecting area can also be directionally blown into the dust collecting funnel 5 through the second filter hole opened on the support plate 9 under the blowing action of the blower 4. This will further enrich the setting form of the electrostatic precipitator structure. Of course, the setting of the support plate 9 is only for supporting the shaking device 3, and it is not necessarily provided with a second filter hole, or more precisely, the size of the support plate 9 can only occupy the main A very small part of the box body 2 or the dust collecting funnel 5, at this time, the support plate 9 can be reinforced and connected to the main box body 2 and/or the dust collector according to any arrangement method in the prior art, such as a column, a rib plate, etc. On the funnel 5, and the dust after shaking can also be directionally blown into the dust collecting funnel 5, avoiding the position of the support plate 9.
