Refrigerating and freezing device

Abstract

The invention provides a refrigerating and freezing device. An ice making chamber is defined in the refrigerating and freezing device, and an ice making unit is arranged in the ice making chamber. The ice-making unit comprises an ice-making box, a refrigerating pipe and at least one circulating fan. At least one ice making groove is defined in the ice making box and used for containing water or ice blocks. And the refrigerating pipe is used for providing cold for the ice-making tank. And the circulating fan is arranged to promote air in the ice-making chamber to circularly flow around the ice-making box. According to the refrigerating and freezing device, cold energy is provided for the ice-making box through the refrigerating pipe to make ice, air in the ice-making chamber is promoted to circularly flow around the ice-making box through the circulating fan, the cold energy of the ice-making box is transmitted to all positions of the ice-making chamber, heat preservation and storage of ice blocks are facilitated, the ice-making efficiency is guaranteed, and meanwhile the ice-making efficiency is improved. And the waste of the cooling capacity of the refrigerating pipe passing through the ice-making box is reduced or even avoided.

Description

technical field [0001] The invention relates to the field of refrigeration and freezing, in particular to a refrigeration and freezing device with an ice making unit. Background technique [0002] At present, most refrigerators with an ice-making compartment installed on the door body mainly introduce the cooling capacity of the freezing compartment into the ice-making compartment of the door body through the air duct. Condensation is easy to occur, the ice making time is long, and the ice making room is easy to mix with the freezing room, which affects the cleanliness of the ice cubes. However, if the door body is directly cooled to make ice, not only the transmission distance of the refrigerant pipeline is too long, the connection is complicated and difficult, but also the cold energy of the refrigerant pipeline is not easily spread to the entire ice-making room. [0003] Considering comprehensively, it is necessary to provide a direct-cooling ice-making unit and a refrig...

[0002] At present, most refrigerators with ice-making compartments on the door body lead the cooling capacity of the freezer compartment into the ice-making compartment of the door body through the air duct. Condensation is easy to occur, the ice-making time is long, and the ice-making compartment is easy to mix with the freezing compartment, which affects the cleanliness of the ice cubes

However, if direct cooling is performed on the door body, not only the transmission distance of the refrigerant pipeline is too long, the connection is complicated and difficult, but also the cooling capacity of the refrigerant pipeline is not easy to spread to the entire ice-making room
