Filter screen cleaning device and indoor air conditioning unit

Abstract

The invention discloses a filter screen cleaning device and an indoor air conditioning unit. The filter screen cleaning device comprises a filter screen, a movable filter screen mechanism and a dust absorption mechanism, wherein the movable filter screen mechanism supports the filter screen and drives the same to move horizontally, and the dust absorption mechanism is fixedly connected with the movable filter screen mechanism and used for cleaning the filter screen. By controlling the movable filter screen mechanism and the dust absorption mechanism to move oppositely, contact absorption plane for the dust absorption is reduced, adsorptive power of a dust absorption chamber is centralized to absorb dust on the surface of the filter screen, and due to a dust absorption groove formed on a dust absorption box holder, the problems that mounting space is limited and dust absorption power is reduced and the like since a conventional dust absorption head is externally connected with a long dust absorption hose and moves back and forth are solved. The filter screen cleaning device is simple in structure, easy to control, low in cost, good in dust absorption reliability, free of influence on appearance of an existing air conditioner, and meanwhile capable of serving as an accessory to be mounted on a conventional air conditioner without a cleaning device, and accordingly more selections can be brought to users.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a filter screen cleaning device for an indoor unit of a cabinet type air conditioner and an air conditioner indoor unit provided with the filter screen cleaning device. Background technique [0002] Usually, a household cabinet air conditioner is composed of a split indoor unit and an outdoor unit. The indoor unit is installed in the user's room and runs for a long time, causing various dust and impurities to accumulate in the air filter on the air inlet side of the air conditioner. The performance has a negative impact, and it also affects the user's healthy use environment. [0003] Conventional air conditioners usually need to manually disassemble the filter screen for cleaning, which brings great inconvenience to users due to various conditions such as installation location. Thereby the air conditioner with automatic cleaning filter screen device arises at the histo...

AI Technical Summary

Problems solved by technology

[0008] The first type of electrostatic dust removal, due to the limitation of the internal installation space of the air conditioner, it is often impossible to install this type of device. In addition, the indoor unit using this type of device generally has a high cost

[0009] The second type of dust removal device is the most widely used, but due to the poor reliability of this type of device for long-term use, especially for special impurities such as fluff, hair and other impurities that cannot be completely and effectively removed

[0010] The third type of water washing cleaning device, on the one hand, needs to increase the water pump, on the other hand, the structure of the whole device is relatively complicated, and the corresponding control method is also relatively cumbersome.
