Electronically-controlled type buffer door closer, refrigeration equipment and door body switch control method

Abstract

The invention discloses an electronically-controlled type buffer door closer, refrigeration equipment and a door body switch control method. The electronically-controlled type buffer door closer comprises a guide rail, a slide block, a crank, a hydraulic buffer, a first connecting rod and a second connecting rod. The slide block is arranged on the guide rail in a sliding manner. One end of the first connecting rod is hinged to the guide rail. The crank is hinged to the position between the slide block and the first connecting rod. The second connecting rod is hinged to the first connecting rod. The hydraulic buffer is mounted on the guide rail and connected with the slide block. A first electromagnet is arranged on the first connecting rod, and a second electromagnet is arranged on the second connecting rod, wherein the second electromagnet is matched with the first electromagnet. By means of the electronically-controlled type buffer door closer, the refrigeration equipment and the door body switch control method, use reliability and user experience of the electronically-controlled type buffer door closer are improved.

Description

technical field [0001] The invention relates to buffer door closers, in particular to an electric-controlled buffer door closer, a refrigeration device and a door body switch control method. Background technique [0002] At present, electronically controlled buffer door closers are widely used in people's daily life. Electrically controlled buffer door closers are usually used for doors in house construction. With the continuous development of home appliance related technologies, some high-end Household appliances are also equipped with electronically controlled buffer door closers. Take refrigeration equipment (refrigerators, freezers or wine cabinets) as an example. The electric control buffer door closer is equipped with a return spring on the hinge to realize the function of automatic door closing, while the electric control buffer door closer is usually equipped with a damper to realize the buffer function, and the damper used generally adopts friction or The way of th...

[0002] At present, electronically controlled cushioning door closers are widely used in people's daily life. Electrically controlled cushioning door closers are usually used for doors in house construction. With the continuous development of home appliance related technologies, some high-end Household appliances are also equipped with electronically controlled buffer door closers. Take refrigeration equipment (refrigerators, freezers or wine cabinets) as an example. The electric control buffer door closer is equipped with a return spring on the hinge to realize the function of automatic door closing, while the electric control buffer door closer is usually equipped with a damper to realize the buffer function, and the damper used generally adopts friction or The way of the spring, which has the following problems in the actual use process: when the user closes the door with insufficient force, the return spring cannot completely overcome the resistance of the damper, and the door body cannot be completely closed; when the user closes the door too hard, If the movement speed of the door body is too high, the buffer effect of the damper will be weakened, and it will have a greater impact on the cabinet body under the action of the return spring.
