Electromagnetic control stepless speed change door opening and closing refrigerator

Abstract

The invention relates to the technical field of refrigerators, in particular to an electromagnetic control stepless speed change door opening and closing refrigerator which comprises a main cabinet body, two cabinet doors are slidably connected into a cabinet opening in the top end of a cabinet body shell of the main cabinet body, electromagnet sets are arranged in the front side wall and the rear side wall of the cabinet opening of the cabinet body shell, and each electromagnet set comprises a plurality of electromagnets. An electric insulation rubber plate is clamped between every two adjacent electromagnets, armatures are embedded in the side walls of the front side and the rear side of the cabinet door, and a single-chip microcomputer control circuit board is further arranged in the main cabinet body. According to the electromagnetic control stepless speed change door opening and closing refrigerator, the electromagnetic principle is used for driving, no complex mechanical mechanism is needed, the refrigerator is small in size and low in manufacturing cost, the maintenance and management trouble caused by mechanical structure faults is omitted, and the refrigerator door is smooth and free of noise in the opening and closing process; the single chip microcomputer is used for controlling opening and closing of the cabinet door, the automation degree of opening and closing of the cabinet door is improved, the remote control function can be achieved, and the problems existing in the manual and common mechanical structure application process are effectively solved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an electromagnetically controlled infinitely variable speed switch door refrigerator. Background technique [0002] Chest freezer is a common large-capacity refrigeration equipment on the market. The opening and closing doors of the horizontal freezers in the market are mostly realized by manual / manual or mechanical structure (mainly referring to motor drive). Among them, using manual opening and closing of the door is a relatively traditional and old-fashioned way, which cannot be automated or remotely controlled. However, the mechanical structure of the horizontal switch door driven by a motor is too complicated. It must have a driving structure, a transmission structure, a sensing structure, and a reversing structure. During use, not only the noise is large, but the cost is too high, and the mechanical structure is prone to failure. Faults lead to difficulties in maint...

Problems solved by technology

Among them, the use of manual opening and closing of the door is a relatively traditional and old-fashioned way, which cannot be automated or remotely controlled.

However, the mechanical structure of the horizontal switch door driven by a motor is too complicated. It must have a driving structure, a transmission structure, a sensing structure, and a reversing structure. During use, not only the noise is large, but the cost is too high, and the mechanical structure is prone to failure. Faults lead to maintenance difficulties, and also increase the overall volume and weight of the freezer, making it inconvenient to move and take up a lot of space
