From the evolution process of air conditioner models, the earliest air conditioner model that appeared was the integrated window-type air conditioner, and the split-type air conditioner has become the mainstream model at present. The floor-standing air conditioner and the wall-mounted air conditioner are two important model branches of current split-type air conditioners. As the name implies, the internal unit structure of a floor-standing air conditioner is column-shaped and placed on the ground in a "floor-standing" manner, while a wall-mounted air conditioner is an air conditioner suspended and mounted on a wall through components such as a back plate hanger. In recent years, air conditioner manufacturers have newly launched a floor-standing air conditioner adopting a bladeless air outlet design on the market, and representative products include the "Sky Cup Air Conditioner" series of products from Haier Group and the like.

The lower connecting rod 18 and the columns 11 form a stable "H"-shaped bottom frame. Install the control board onto the mounting plate 7 of the lower connecting rod 18 and fix it with screws. Then cover it with the cover plate 8 to protect the control board. Finally, the upper connecting rod 17 is fixed to the top of the two columns 11 with screws, so that the frame 1 is in the shape of a "latch". After the upper connecting rod 17 is installed, the controller circuit board is placed in the rectangular mounting box 5 of the upper connecting rod 17. The circuit board is fastened by the internal mounting structure and connected to form a complete frame 1. Then the outer shell assembly will be assembled with the skeleton:
