Main control panel box structure for refrigerator mechanical room and assembly method thereof

Abstract

The invention discloses a main control panel box structure for a refrigerator mechanical room and an assembly method thereof, and relates to the technical field of refrigerators. In the invention, a wire outlet port is formed in one end surface of the main control panel box; claws are arranged on the two sides of the wire outlet port; a screw fixing seat is arranged the other end surface of the main control panel box; a rectangular plate is arranged on one end of a box cover; the box cover is fixed on the main control panel box through a tapping screw; a main control panel is installed in themain control panel box; the main control panel is fixed in the main control panel box through self-tapping screws; wire harnesses are inserted into the main control panel; the wire harnesses pass through the wire outlet port; and the main control panel box is fixed to the refrigerator through a foaming leg bracket. The invention adjusts a locking position of the wire harness by adjusting the tapping distance of the self-tapping screw, and avoids the cumbersome and unstable processes; the assembly is simple, and the manufacturing efficiency is improved; during assembly of the main control panelbox, one side of the main control panel box is inserted into the foaming leg bracket through the claws, and the other side of the main control panel box is fixed by screws; and noise caused by vibration of product and vibration of a compressor can be prevented.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a structure of a main control board box used in a refrigerator machine room and an assembly method thereof. Background technique [0002] Refrigerator is a household appliance commonly used in people's daily life. The daily operation of the refrigerator is mainly controlled by the main control board. The main control board will control the normal operation of the refrigerator according to the operating information such as the temperature set by the user; [0003] At present, for refrigerators, the main control board box is fixed inside the mechanical room, and there are the following problems: 1. After the wiring harness terminals are plugged in, they need to be fixed with tension cables, which is a troublesome process; 2. The main control board box has no cover, and the metal fingers can touch it. It cannot meet the IEC safety requirements; 3. The wire harness ...
