The refrigeration appliance 10 may be a single door refrigeration appliance, a double door refrigeration appliance, a triple door refrigeration appliance, a side-by-side refrigeration appliance, a cross door refrigeration appliance, or the like.

Referring to fig. 1 to 5, the refrigeration apparatus 10 may include a cabinet 100 and a door assembly 200, the cabinet 100 may have a cold space 101, the door assembly 200 may include a transparent door 210 and a transparent display case 220, the transparent display case 220 may be mounted on an inner side 210a (see fig. 6) of the transparent door 210, the transparent door 210 may be rotatably connected to the cabinet 100 to open or close the cold space 101, the transparent display case 220 may have a storage space 221d, the transparent display case 220 may be further provided with a cold guide 220a, and the cold guide 220a is positioned between the cold space 101 and the storage space 221d when the transparent door 210 closes the cold space 101. In this way, when the temperature of the cold space 101 is lower than the temperature of the storage space 221d, the cold guide 220a can transfer the cold energy of the cold space 101 to the storage space 221d when the transparent door 210 closes the cold space 101, thereby increasing the cold energy of the storage space 221d, and further decreasing the temperature of the storage space 221d, and helping the storage space 221d to store the articles.

In addition, when the transparent door 210 closes the case 100, a user can directly see the space condition of the storage space 221d of the transparent showcase 220 through the door assembly 200; when the transparent door 210 opens the case 100, a user can also see the space condition of the storage space 221d of the transparent display case 220 through the transparent display case 220, thereby helping the user to conveniently, rapidly and accurately take or put articles in the transparent display case 220.

In addition, when the transparent door 210 closes the case 100, the user can directly watch the articles placed in the storage space 221d of the transparent display case 220, so that the articles placed in the storage space 221d of the transparent display case 220 have a better viewing effect, which is helpful for improving the user experience.

Referring to fig. 3 to 5, in some embodiments, the cold guide 220a may be a through hole, and when the transparent door 210 closes the cold space 101, the through hole may be communicated with the cold space 101 and the storage space 221d, so that the cold space 101 flows to the storage space 221d with a lower temperature, thereby increasing the cold capacity of the storage space 221d, and further reducing the temperature of the storage space 221d.

In some embodiments, the through holes may include a first sub through hole 220b and a second sub through hole 220c, and the first sub through hole 220b and the second sub through hole 220c may be respectively located at the top and bottom of the transparent display case 220, and when the transparent door 210 closes the cold space 101, the first sub through hole 220b and the second sub through hole 220c are both communicated with the cold space 101 and the storage space 221d.

Specifically, since the density of the air having the higher temperature in the cold space 101 is smaller than that of the air having the lower temperature, the air having the higher temperature in the cold space 101 is located above the air having the lower temperature, that is, the air having the lower temperature in the cold space 101 is sunk, at this time, the air having the lower temperature in the cold space 101 may enter the storage space 221d from the second sub-through hole 220c, and the air having the higher temperature in the storage space 221d may flow from the first sub-through hole 220b to the cold space 101.

In this way, the air with a lower temperature in the cold space 101 may enter the storage space 221d, and at the same time, the air with a higher temperature in the storage space 221d may enter the cold space 101, so that the temperature in the storage space 221d may be rapidly reduced, which is helpful for rapidly reducing the temperature of the storage space 221d.

In some embodiments, the door assembly 200 may further include a wind-guiding grille rotatably mounted to the through-hole to adjust the size of the through-hole. Specifically, the opening and closing angle of the air guide grille is adjusted by rotating the air guide grille, so that the size of the through hole is adjusted, and the cooling capacity of the cooling space 101 transferred to the storage space 221d is controlled more accurately.

In some embodiments, the cold guide 220a may be a cold guide member, which may be a cold guide bar, a cold guide pipe, a cold guide plate, or the like. The heat conducting member may be made of a material having high heat conducting property, for example, the heat conducting member may be made of diamond, and for example, the heat conducting member may be made of a metal having high heat conducting property such as gold, silver, copper, etc., so that the cold conducting member can transfer cold.

When the transparent door 210 closes the cold space 101, the cold guide member is adapted to thermally and conductively contact the air of the cold space 101 and the air of the storage space 221d. In this manner, when the temperature of the cold space 101 is lower than the temperature of the storage space 221d, the cold guide member may transfer the cold of the cold space 101 to the storage space 221d when the transparent door 210 closes the cold space 101, thereby reducing the temperature of the storage space 221d.

The outer contour of the case 100 may be substantially rectangular or square, and the cold space 101 of the case 100 may accommodate various objects. Wherein the refrigerating apparatus 10 may be provided with a refrigerating part, which may reduce the temperature of air, and the refrigerating part may include an evaporator, a compressor, an expansion valve, and the like, thereby reducing the temperature of air of the cold space 101, and thus making the temperature of air of the cold space 101 lower than that of the storage space 221d.
