Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning structures, in particular to a hanging type air-conditioning indoor unit. Background Art

[0002] The air outlet of the indoor unit of the air conditioner is composed of the shell and the base, so that the air conditioner can discharge air. The shell of the indoor unit of the air conditioner is usually fixed to the base by two or three screws. The specific fixing structure is to set an installation pit on the shell, and a screw through hole is opened at the bottom of the pit. The screw passes through the screw through hole at the bottom of the shell pit and is fixed to the base to achieve the locking and fixing of the shell and the base. After fixing the screws, it is necessary to install 3 screw covers on the pit of the shell to fill the pit on the shell and restore the original shape and structure of the shell. There are two purposes for installing the screw cover. The first is for decoration to avoid the unsightly exposed screws. The second is because the pit is at the air outlet. If it is not filled, it will affect the air volume and direction of the air outlet. Even in special environments, condensation will occur, so that water will accumulate in this pit, affecting the user experience.

[0003] However, there are many problems and shortcomings in the traditional fixation between the shell and the base. The first is that during mass production, it cannot be guaranteed that the color of the shell and the screw cover is exactly the same, so there will be visual color difference, affecting the overall appearance. The second is that it will reduce the production efficiency of the air conditioner. On the production line, the screws need to be fixed first, and then the screw covers can be installed. The process of installing the screw covers reduces production efficiency. The third is that additional costs are added, including the material cost of the screw cover itself, the mold cost of the screw cover, and the labor cost and time cost of installing the production screw cover and installing the screw cover. The fourth is that there is a risk of the screw cover falling off and being lost. During the transportation and installation of the air conditioner, there is a risk of the screw cover falling off the shell. The position of the missing screw cover will directly expose the screws and the shell pits, affecting the overall appearance of the product and causing risks such as user complaints. Summary of the invention

[0004] The purpose of the present invention is to provide a wall-mounted air conditioner indoor unit, aiming to solve the technical problems in the prior art that the screw head is located outside the shell, the installation of a screw cover affects the appearance, reduces production efficiency, increases costs, and the screw cover is easy to fall off.
