Problems solved by technology

However, different areas of the refrigeration and freezing device have different cooling requirements. If the air outlets of all the air ducts are opened at the same time, it may cause waste of cooling capacity.
[0003] Although there are already some refrigerating and freezing devices with split air supply function, this kind of refrigerating and freezing devices has relatively high requirements for air path design, which may easily lead to the loss of air volume.

Abstract

The invention discloses a refrigerating and freezing device which comprises an air way panel. Multiple air ways are formed on the air way panel. Each air way is provided with an air outlet, and an airdoor is arranged at the position of each air outlet. In addition, the refrigerating and freezing device further comprises a linking device connected to the multiple air doors so that the multiple airdoors can move, and the respective air discharging area of the multiple air outlets is adjusted. By means of the refrigerating and freezing device, the respective air discharging area of the multipleair outlets can be adjusted according to user needs, supply of the cooling capacity at the position of each air outlet is reduced or increased, food in the refrigerating and freezing device can be better preserved, energy is saved, and the refrigerating and freezing device is more intelligent.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration and freezing device. Background technique [0002] At present, the tuyere openings of all the air ducts of the refrigerating and freezing devices appearing on the market are opened or closed simultaneously. However, different regions of the refrigerating and freezing device have different cooling requirements. If the air outlets of all the air ducts are opened at the same time, cooling capacity may be wasted. [0003] Although there have been some refrigerating and freezing devices with split air supply function, such refrigerating and freezing devices have relatively high requirements for air path design, which may easily lead to loss of air volume. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a storage device that solves the above problems or at least partially solves the above ...
