Abstract

The invention discloses a junction box for an air-conditioning unit, which is a square structure, the bottom and the back of which are open, and other surfaces are closed; When it is not in use, hang it on the inside of the cabinet door of the control cabinet. When it needs to be used, the junction box is installed at the wire inlet hole, and the opening on the back is aligned with the wire inlet hole. . In the present invention, by adding a junction box, it is installed on the inner side of the cabinet door of the control cabinet when not in use, and will not occupy space and affect the normal use of the air conditioning unit; and it is removed from the cabinet door and installed on the control cabinet when it needs to be used. The wire inlet can prevent rain and dust, protect the components inside the control cabinet, and make the appearance of the control cabinet more beautiful.

Description

technical field [0001] The invention relates to the technical field of air-conditioning unit equipment, in particular to the structure at the line inlet of the control cabinet of the air-conditioning unit. Background technique [0002] Central air-conditioning units are widely used in various large buildings because of their environmental protection, energy saving, excellent performance, stability and reliability. The central air conditioner is controlled by the control cabinet on the side of the unit. The control switch of each component is set in the control cabinet, which is the central nervous system of the air conditioning unit. The power lines of each component in the unit must be connected to the control cabinet. At present, the general practice is to open a wire inlet hole on the side of the control cabinet, and the power cord is connected through the wire inlet hole, and the wire inlet hole is not closed. However, the central air conditioner is often installed outd...
