Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning indoor unit installation, in particular to an air-conditioning indoor unit installation structure which is convenient for maintenance. Background Art

[0002] When installing the indoor unit of a central air conditioner, it is usually installed on the floor via a hanger. Specifically, a hole is drilled in the floor, an expansion sleeve is installed on the upper end of the hanger and then inserted into the floor. The hanger is short, and the lower end of the hanger matches the installation hole on the upper surface of the indoor unit.

[0003] However, there are problems as follows: a gypsum board is laid as a ceiling through a hanger and a keel below the indoor unit, an air vent is installed on the ceiling, and an air vent component is installed at the air vent; there is a certain height distance from the air vent to the indoor unit and the hanger installation location. When the indoor unit is damaged and needs to be repaired, it is difficult to remove the indoor unit.

[0004] Based on customer feedback, the installation structure inside the central air conditioner is improved by lowering the height of the locking point so that workers can remove the air conditioner at the air outlet. In addition, after the locking height is lowered, the distance between the locking point and the floor slab is increased. In order to ensure the reliability of the installation, other structures have been improved. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide an air conditioner indoor unit installation structure which can be disassembled for maintenance without damaging the gypsum board and is convenient for disassembly and maintenance.
