Air Filters and Their Uses

Abstract

The invention relates to an air filter device which comprises an outer shell 1, a cover plate 2, net winding and unwinding mechanisms 3a and 3b, a transfer mechanism 4, a gear 14 and a filter net component 6. The net winding and unwinding mechanism 3a or 3b is connected with the gear 14, and the filter net component 6 is led out from the net winding and unwinding mechanism 3a or 3b, covers an air inlet face, then covers an air outlet face after passing through the transfer mechanism 4, and then returns to the net winding and unwinding mechanism 3b or 3a. The filter net component 6 is synchronous with the net winding and unwinding mechanisms 3a and 3b through the gear 14, the filter net component 6 circulates in the net winding and unwinding mechanism 3a or 3b through the transfer mechanism 4 to be collected by the net winding and unwinding mechanism 3a or 3b, and the other net winding and unwinding mechanism 3b or 3a synchronously releases the filter net component 6. The air filter device can be applied to filter devices or components in air conditioners, and is used for filtering out and adsorbing PM particles in air.

Description

technical field [0001] The present invention relates to an air filter device and its application, in particular to an air filter device or components used in household air conditioners. [0002] technical background [0003] At present, the air conditioner generally adopts two-side or three-side air intake, and the air filter is placed on the air intake grille. When the air conditioner is working, the air enters through the air intake grille, is purified by the air filter, passes through the heat exchanger, and then comes out from the air outlet, so that the indoor air is conditioned by circulation. [0004] At present, some air-conditioning filters adopt a structure that is fully removable and easy to clean or automatically cleaned, among which: [0005] (1) The fully dismantled, washable and easy-to-clean structure is as follows: the filter screen is a separate component, which can be taken out or inserted from the air inlet grille of the air conditioner by opening the pan...

AI Technical Summary

Problems solved by technology

[0008] ①Easy to accumulate dust, affecting the cooling and heating effect;

[0009] ②The accumulated dust on the filter screen will enter the room with the air flow, affecting the indoor air quality; and

[0010] ③Regularly open the air intake grille and remove the filter for cleaning. It is often difficult to open the panel. You need to use tools such as tables and chairs to operate. The operation is cumbersome and dangerous

[0012] ①When cleaning, some filters need to stick out of the machine, affecting the beauty of home decoration;

[0013] ②The filter screen is rolled up inside the machine, adopting free extension or meandering, which increases the volume and cost of the indoor unit; and

[0014] ③The filter screen is not cleaned cleanly and needs to be cleaned manually again

[0015] Due to the above-mentioned technical problems still exist in the prior art, there is an urgent need for a new filter device, especially a filter device or component used in a household air conditioner, thereby providing a filter that not only solves the impact of dust accumulation on the air filter screen Cooling and heating effect problems, troubles caused by manual cleaning of the filter, automatic dust removal that affects the appearance of home decoration, and the filter is not cleaned cleanly; and the dusty filter can be automatically collected multiple times according to user settings.
