Description

Technical Field

[0002] The outdoor unit of the modular air-conditioning unit is generally installed outdoors, and an electric control module is provided in the outdoor unit, which is used to realize the connection and control with the indoor unit. The electric control module is an important module for the operation of the air conditioner. Once damaged, the unit will not be able to start. If rainwater penetrates into the unit on rainy days, it will seriously affect the life and safety of the air conditioner. Therefore, the electric control module is generally integrated in an electric control box, and a detachable box cover is provided to facilitate the maintenance and repair of the electric control module. The existing electric control box and the box cover are usually connected together via a snap-on structure or screws.
