Description

Technical Field

[0001] The utility model relates to the technical field of central air conditioners, in particular to a grille plate used for an indoor unit of a central air conditioner. Background Art

[0002] The central air conditioning system is composed of one or more cold and heat source systems and multiple air conditioning systems. This system is different from the traditional refrigerant air conditioner, which centrally processes air to meet the comfort requirements. In the prior art, the announcement number CN220287702U discloses a high-strength central air conditioning grille plate. When installing this grille plate, the installer places the entire grille plate at the air outlet of the central air conditioner, and then uses bolts to pass through the installation holes and then screw them with the air outlet of the central air conditioner to achieve the installation of the entire grille plate. When installing this grille plate, the staff needs to use external tools to continuously tighten multiple groups of bolts, and the steps are relatively cumbersome. In addition, when the customer wants to clean the grille plate by himself, there may be a long disassembly time or a lack of wrenches, which to a certain extent reduces the convenience of disassembly of the grille plate.
