Embodiment Construction
[0050] figure 1 and 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, th...

Abstract
The invention provides a refrigerator with a double-layer door structure. The refrigerator comprises a refrigerator body, an inner-layer door, an outer-layer door, a lighting device, a lighting switchand a transition piece, wherein a storage compartment is defined in the refrigerator body, the inner-layer door is connected to the refrigerator body in an open and closed mode, a through hole is formed in the position, close to the edge, of the inner-layer door, the outer-layer door is connected to the outer side of the inner-layer door in an open and closed mode, the inner-layer door and the outer-layer door can be opened and closed independently or together, the lighting device is used for lighting the storage compartment, the lighting switch is arranged on the part, making contact with the inner-layer door, of the refrigerator body, the contact point position of the lighting switch is opposite to the through hole, the transition piece is integrally arranged in the through hole in a penetrating mode, and the length of the transition piece is larger than the length of the through hole, so that the two ends of the transition piece can abut against contact points of the outer-layer door and the lighting switch correspondingly. According to the refrigerator with the double-layer door structure, the lighting switch is closed or opened by using a mechanical structure, the structure is simple, switch control components are reduced, and the control program of a circuit is simplified.
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...
