The multiple air doors and the air door heater can also increase the power consumption of the whole refrigerator, so that the energy efficiency of the refrigerator is reduced.

As shown in fig. 2, for the embodiment of the centralized air supply device for a multi-temperature-zone refrigerator provided by the present invention, a refrigerator with three chambers (three temperature zones) is taken as an example, that is, the refrigerator has three temperature zones: warm zone 1, warm zone 2, warm zone 3. The air supply device comprises: the refrigerator comprises a refrigerator shell 100, three

compartments

1, 2 and 3, a heat exchange chamber 200, an evaporator 13, an electric heater 12, and air inlet and return ducts of the compartments. The

air inlets

7, 8, 10 of the three chambers are independently communicated with a subarea air supply outlet 5 on the left side wall body of the heat exchange cavity 200, namely, the air inlet channels of the chambers are not communicated with each other and respectively supply air. In this embodiment, as can be seen from fig. 2, on the basis of the existing air supply structure of the refrigerator, the

partition plates

31 and 32 are used to independently communicate the

air inlets

7, 8 and 10 of the three compartments with the partitioned air supply outlet 5 of the heat exchange chamber 200, and simultaneously, air inlet dampers and corresponding electric heaters of the compartments are eliminated. According to the requirement, the air inlets of the chambers can be independently communicated with the subarea air supply outlets of the heat exchange chamber by adopting a pipeline structure. The subarea air supply outlet 5 is internally provided with a subarea air supply mechanism which can selectively open or close the air inlet of the compartment according to the requirement of the refrigerator.

When a control motor (not shown in the figure) drives the rotary baffle plate 24 to rotate relative to the fixed temperature zone air inlet plate 20, the air inlet of the related compartment can be opened or closed. A blower fan 4 (shown in fig. 2) may be further provided in the intake duct 25 for forcibly circulating cool air inside the refrigerator.

As shown in fig. 5, fig. 6, and fig. 7, the rotary damper 24 in the zoned air supply mechanism opens the air inlet 21 of the compartment 1, or opens the air inlet 23 of the compartment 2, or opens the air inlet 24 of the compartment 3, respectively; namely, the rotary baffle plate 24 only opens the air inlet of one chamber, and simultaneously closes the air inlets of the other two chambers.

As shown in fig. 8, the rotary damper 24 in the zoned air delivery mechanism opens the air intakes of all compartments.

For example, any two or three air inlets on the temperature zone air inlet plate 20 are opened.

Referring to fig. 2, the utility model also provides a multi-temperature-zone refrigerator, which comprises a multi-temperature-zone refrigerator centralized air supply device. When the unit is in operation, if the temperature zone 1 has a refrigeration demand, the rotary baffle 24 is controlled to open the air inlet 21 of the temperature zone 1, as shown in fig. 5. Cold air cooled by the evaporator 13 is sucked into an air inlet duct of the temperature zone 1 through an air inlet 21 and then enters the temperature zone 1, the cold air returns to the air inlet of the heat exchange chamber 200 through a return air duct formed by the

return air inlets

6 and 101 and the shell 100 after heat exchange, is cooled by the evaporator 13 and then is input into the temperature zone 1 again until the temperature of the temperature zone 1 meets the set requirement, and then the air inlet 21 is closed. Similarly, when the temperature zone 2 has a refrigeration request, the motor is controlled to drive the rotary baffle plate 24 to rotate to the position shown in fig. 6, cold air is sucked into the air inlet duct of the temperature zone 2 through the air inlet 22 and then enters the temperature zone 2, and after heat exchange, the cold air passes through the air return opening 9 of the cold air inlet duct and forms a return air duct with the shell to return to the air inlet of the heat exchange chamber 200; or when the temperature zone 3 has a refrigeration request, controlling the motor to drive the rotary baffle plate 24 to rotate to the position shown in fig. 7, sucking cold air into the air inlet duct of the temperature zone 3 through the air inlet 23 and then entering the temperature zone 3, forming a return air duct through the return air inlet 11 and the shell after heat exchange and returning to the air inlet of the heat exchange chamber 200, and circulating the steps until the temperature of the temperature zone meets the set requirement, and then closing the corresponding air inlet hole.
