Door-in-door structure of fridge

Abstract

The invention discloses a door-in-door structure of a fridge. The door-in-door structure comprises a fridge door, an interior casing and a bar counter, wherein the interior casing is embedded in the fridge door, and the bar counter is located on one frame of the interior casing and arranged in the interior casing in a connected mode through hinges. The frame, provided with no hinge, of the interior casing is at least provided with a locking mechanism. The locking mechanism comprises an electromagnetic coil and a lock catch which is located on the side, close to the bar counter, of the electromagnetic coil and connected with the bar counter in an inserted mode. The lock catch comprises a body part and an inserting-connecting part connected with the body part. The lock catch is made of metal materials or magnetic materials. The position of the lock catch is controlled through power on-off of the electromagnetic coil, in this way, the bar counter can be opened and closed, the door opening force of the bar counter is reduced, the influence on the appearance of the fridge by the locking mechanism is reduced, and the bar counter can be automatically opened.

Description

technical field [0001] The invention relates to the technical field of door-in-door refrigerators, in particular to a door-in-door structure of a refrigerator door based on electromagnetic switches. Background technique [0002] With the continuous improvement of people's living standards and the deepening of low-carbon concepts, some high-end refrigerators on the market have added refrigerator bars and door-in-doors to improve appearance and quality and reduce energy consumption in order to attract consumers. The locking mechanism of the existing bar counter or the door-in-door is generally a mechanical push switch. However, mechanical push switches have two major disadvantages: [0003] 1. Due to the use of mechanical push switches, it is necessary to press a certain stroke when opening the door. This stroke needs to overcome the deformation force of the bar table and the elastic force of the mechanical switch. However, the door seal of the bar table is relatively hard wh...

Problems solved by technology

[0003] 1. Due to the use of mechanical push switches, it is necessary to press a certain stroke when opening the door. This stroke needs to overcome the deformation force of the bar table and the elastic force of the mechanical switch. However, the door seal of the bar table is relatively hard when it is in a low temperature state, and it is processed by the corner of the door seal. The impact of the state, resulting in the need to provide a larger door opening force

Generally, the door opening force ranges from 3 to 6kgf, which seriously affects the user experience

[0004] 2. Since the mechanical push switch is installed on the front of the inner frame, there is a protrusion or a cover on the front of the inner frame to hide the push switch, which affects the overall appearance quality of the refrigerator bar
