Embodiment Construction

[0050] figure 1 with 2 is a schematic diagram of a refrigerator 100 with a double door structure according to an embodiment of the present invention. The refrigerator 100 with a double-layer door structure in the embodiment of the present invention is a side-by-side refrigerator, and may generally include: a box body 10 , a first door body 20 , a second door body 30 , a lighting device, and a lighting switch 60 .

[0051] There are multiple storage compartments inside the box body 10 . Storage compartments are used to store food. The plurality of storage compartments in the embodiment of the present invention may include a refrigerating room, a freezing room where vegetables are often stored, and may also include a temperature-changing room and the like.

[0052] The first door body 20 and the second door body 30 are respectively openably and closably disposed on the front side of the box body 10 to open and close the storage compartment of the box body 10 . For example, t...

Abstract

The present invention provides a refrigerator with a double-layer door structure, comprising: a box body defining a storage compartment inside; an inner layer door that is openably and closably connected to the box body, and opens at a position close to the edge of the box body; There are through holes; the outer door is openably and closably connected to the outside of the inner door, and the inner door and the outer door can be opened and closed independently or together; the lighting device is used to The lighting of the storage compartment; the lighting switch is arranged on the part of the box body in contact with the inner door, and its contact position is opposite to the through hole; the transition piece is integrally installed in the through hole Inside, the length of which is greater than the length of the through hole, so that the two ends can be interfered by the contacts of the outer door and the light switch respectively. The refrigerator with the double-layer door structure of the present invention uses a mechanical structure to close or break the light switch, has a simple structure, reduces switch control components, and simplifies the control program of the circuit.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing equipment, in particular to a refrigerator with a double-layer door structure. Background technique [0002] A lighting device is usually installed in a refrigerator compartment or a freezer compartment to improve the performance of the refrigerator. The lighting switch of the existing refrigerator with a double-layer door structure is to install a Hall switch on the box body and the inner door respectively, pre-install magnets on the corresponding positions on the inner door and the outer door, and pass the electric switch. Magnetically sense the opening and closing of the inner door and the outer door to achieve the switch control of the lighting device. Using two Hall switches, the design of the control circuit is complicated, the wiring is complicated, and the design cost is high. Contents of the invention [0003] The object of the present invention is to provide a refr...
