Description

Technical Field

[0001] The utility model 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 air conditioner's indoor unit is formed by the housing and the base, allowing the air to flow out. The housing of a wall-mounted indoor unit is typically secured to the base with two or three screws. The specific fixing structure is a mounting recess in the housing with a screw hole at the bottom. The screw passes through the screw hole at the bottom of the housing recess and is secured to the base, locking the housing and base. After securing the screws, three screw covers need to be installed in the recess of the housing to fill the recess and restore the original shape and structure of the housing. The screw covers serve two purposes. The first is for decorative purposes, to avoid the unsightly appearance of exposed screws. The second is because the recess is located at the air outlet. If it is not filled, it will affect the air volume and direction of the air. In certain environments, condensation may even form, leading to water accumulation in the recess, affecting the user experience.

[0003] However, the traditional fixation between the shell and the base has many problems and shortcomings. 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 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 that the screw cover will fall off the shell. The position where the screw cover is missing will directly expose the screws and the shell pits, affecting the overall appearance of the product and causing risks such as user complaints.
