Description

TECHNICAL FIELD

[0001] The present invention relates to the field of refrigerator doors, and specifically relates to a refrigerator door having a see-through window.

BACKGROUND

[0002] A refrigerator is a refrigeration apparatus that maintains a constant low temperature. It reduces the temperature inside the refrigerator by discharging cold air generated by a compressor, a condenser, an expansion valve and an evaporator in refrigeration cycles, so that food stored in the refrigerator is in a frozen or refrigerated state. The refrigerator is divided into a freezer compartment and a refrigerator compartment according to a freezing function and a refrigerating function. In the structure of both the freezer compartment and the refrigerator compartment, a refrigerator door is included. The refrigerator door serves as an insulating wall to ensures that the freezer compartment and the refrigerator compartment are isolated from the external environment.

[0003] Generally, the refrigerator doors for opening or closing the freezer compartments and the refrigerator compartments are opaque. To take the food in the freezer compartment or the refrigerator compartment, a user needs to first open the door of the freezer compartment or the refrigerator compartment, and then looks around the freezer compartment and the refrigerator compartment in the open state to find the specific desired food, which takes a certain time.

[0004] Especially for refrigerators with wine cabinets, in order to ensure the quality of the wine in the wine cabinets, the temperature inside the refrigerators needs to be strictly controlled to keep constant. However, when it is necessary to access the wine cabinet, such as opening the door for search, the temperature inside the wine cabinet will change, and such change may even lead to imbalance in serious cases.

[0005] In order to solve the above-mentioned problems, existing refrigerators are provided with see-through windows on the doors. Users can observe articles inside the refrigerators through the see-through windows. However, due to the split design of the see-through window and the door, that is, a mounting opening is provided on the door, and then the see-through window is embedded in the door, it is urgent to solve the problem of undesirable fixing reliability of the see-through window and unsatisfactory sealing performance at the connection point. The existing refrigerator door having the see-through window has poor sealing performance between the door and the see-through window, resulting in obvious heat exchange between the inside of the refrigerator and the outside world, that is, resulting in poor insulation effect and increased energy consumption.
