Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a dust suction device for repairing a precision air conditioner. Background Art

[0002] Precision air conditioning, also known as constant temperature and humidity air conditioning (CTAC) or computer room air conditioning (CRAC), is a type of air conditioning system specifically designed to meet stringent temperature and humidity requirements. Compared to standard household or commercial air conditioners, precision air conditioners offer higher control accuracy and stability, making them suitable for data centers, laboratories, medical facilities, museums, and other locations requiring precise environmental control.

[0003] A Chinese utility model patent, publication number CN204227668U, published on March 25, 2015, discloses a dust removal device for an air conditioner and an air conditioner. The dust removal device for the air conditioner includes a dust collection module having a dust collection filter element; and a charging module having a discharge unit and an electrode plate, the discharge unit being positioned between the electrode plate and the dust collection filter element. The charging module and the dust collection module are connected by a snap-fit connection. The dust removal device for the air conditioner provided by this utility model utilizes a snap-fit connection between the charging module and the dust collection module, effectively addressing the issues of low assembly efficiency, high cost, difficult cleaning, and poor reliability associated with existing dust removal devices. The device is also safe, reliable, cost-effective, and highly efficient, further embodying the company's design philosophy for product optimization.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the dust removal device in the prior art is used for one air-conditioning model only, which makes it impossible to adapt to air-conditioning equipment of the same size and shape. The dust accumulated during daily use needs to be cleaned with cleaning items such as towels. However, the air-conditioning grille has many corners and right angles. When the gap in the grille is small, the fingers have to push the towel to insert for cleaning, resulting in incomplete cleaning. Utility Model Content
