Document Type and Number:
WIPO Patent Application WO/2022/188450
Kind Code:
A1
Abstract:
Provided are an electrical appliance box structure, an air conditioner indoor unit and an air conditioner outdoor unit. The electrical appliance box structure comprises: a PA alloy box and a cover plate, wherein the top of the PA alloy box is provided with an opening, and the cover plate is detachably mounted at the opening; and a mounting chamber for mounting a transformer is provided in the PA alloy box, and several mounting interfaces in communication with the mounting chamber are provided on the PA alloy box at positions corresponding to the mounting chamber. According to the electrical appliance box structure provided in the present application, the box is made of a PA alloy, which is a new flame-retardant material, such that the whole structure does not need to be riveted to an iron sheet on the outside, thereby greatly improving the overall production efficiency. Since the mounting interfaces on the PA alloy box are in communication with the mounting chamber, the transformer can be fixed in the mounting chamber by means of connectors at the mounting interfaces, such that the opening area of the box is greatly reduced, so as to effectively improve the sealing performance of the whole electrical appliance box structure, thereby improving the safety and stability of the electrical appliance box structure during normal operation.
