A refrigeration and freezing device

Abstract

The invention relates to a cold storage refrigerating device which comprises a box. The box is internally provided with a plurality of separated storage spaces, one storage space is provided with a plurality of separation positions and movable partition plates removably arranged at any separation position. Each storage section between every two adjacent separation positions and between the uppermost separation position and the top wall of the storage space is provided with at least one normally open air inlet and a reuse air port for optionally letting air enter or return, and a storage section between the lowermost separation position and the bottom wall of the storage space is internally provided with at least one normally open air inlet and a normally open air return port. The number and size of the normally open air inlets in each storage section and a state of each reuse air port are configured to make a sub-storage space above the movable partition plate and a sub-storage space located below the movable partition plate have at least one air port for air return, and the total area of the air port of each sub-storage space for air inflow is matched with the volume of the sub-storage space.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a refrigeration and freezing device. Background technique [0002] In order to meet people's different demands on the volume of refrigerators in daily life, some existing refrigerators are usually provided with movable partitions in the storage compartment, so as to achieve the purpose of adjusting the volume of the storage compartment by changing the position of the partitions. In order to be able to control the temperature of storage compartments with variable volumes, the following methods are usually adopted in the prior art: first, two sets of independent refrigeration control systems and air circulation loops are used, and the temperature in each storage compartment is used to A temperature sensor controls the temperature in each storage room; the structure of the refrigerator using this method is quite complicated, the cost is high, and the temperature in the storag...

Problems solved by technology

In order to be able to control the temperature of storage compartments with variable volumes, the following methods are usually adopted in the prior art: first, two sets of independent refrigeration control systems and air circulation loops are used, and the temperature in each storage compartment is used to A temperature sensor controls the temperature in each storage room; the structure of the refrigerator using this method is quite complicated, the cost is high, and the temperature in the storage room is not easy to control

The second is to use multiple evaporators and multiple temperature sensors to realize temperature control in each storage room; the mutual influence between multiple evaporators of refrigerators in this way is large, it is difficult to achieve precise control, and the cost is relatively high. high

The third is to use the independent air outlets and temperature compensation heaters in each storage room to adjust the temperature in each storage room; in this way, the number of internal heaters in the refrigerator is large, and each storage room Each requires a temperature sensor, which is not conducive to energy saving and increases the cost of the refrigerator
