The first temperature detection device 400 and the second temperature detection device 500 are preferably temperature sensors, and the controller 600 can know the temperatures of the storage compartment 100 and the dry compartment 200 in real time through the first temperature detection device 400 and the second temperature detection device 500.
FIG. 3 illustrates control logic for a semiconductor refrigeration module 300 in a refrigerator having a dry compartment in accordance with one embodiment of the present inventionAnd editing the schematic diagram. As shown in fig. 3, in step S301, the first temperature detecting device 400 detects that the temperature R of the storage compartment 100 is higher than or equal to a preset first starting temperature RonAt this time, the controller 600 turns on the air supply system 700 to supply the cooling air flow to the storage compartment 100 and the dry compartment 200, and turns on the semiconductor cooling module 300. Wherein the first boot temperature RonThe temperature at which the storage compartment 100 starts to cool is a higher temperature, and the storage compartment 100 reaches the first starting temperature RonMeanwhile, the air supply system 700 is turned on to supply the refrigerating air flow to the storage compartment 100 and the dry compartment 200 to reduce the temperatures of the storage compartment 100 and the dry compartment 200, and the semiconductor refrigerating module 300 is turned on to delay the refrigerating speed of the dry compartment 200, prolong the air blowing time of the dry compartment 200 and reduce the humidity of the dry compartment 200. In addition, the refrigerating speed of the storage compartment 100 can be increased.
In addition, the semiconductor cooling module 300 is powered by the controller 600, and the controller 600 is actually a computer board.
In step S302, after the semiconductor refrigeration module 300 is turned on for a first predetermined period of time, the controller 600 determines whether the temperature R of the storage compartment 100 is lower than or equal to a preset first shutdown temperature RoffIf yes, the air supply system 700 and the semiconductor refrigeration module 300 are turned off. The first predetermined time period is preferably 30-50 seconds, in this embodiment, 30 seconds is selected, and the first shutdown temperature R is setoffThe first shutdown temperature is a lower temperature for the storage compartment 100 to stop cooling. The temperature R of the controller 600 in the storage compartment 100 is lower than or equal to the first shutdown temperature RoffThe reason why the air supply system 700 is turned off is that the temperature of the storage compartment 100 is low enough at this time, the air supply system 700 does not need to be turned on continuously for cooling, and the semiconductor cooling module 300 is turned off correspondingly after the air supply system 700 is turned off. It should be noted that the first predetermined time period is determined according to actual situations, and the present invention is not limited to this.
In step S303, after the semiconductor refrigeration module 300 is turned off for a second predetermined period of time, the controller 600 will determine whether the temperature R of the storage compartment 100 is lower than the predetermined temperature ROr equal to the first shutdown temperature Roff. The second predetermined time period is preferably 3 minutes to 8 minutes, and 3 minutes is selected in the embodiment. It should be noted that the second predetermined time period is determined according to actual situations, and the present invention is not limited to this.
In step S302, if it is determined that the temperature R of the storage compartment 100 is higher than the first shutdown temperature RoffIn step S304, the controller 600 continues to determine whether the temperature S of the dry compartment 200 is higher than or equal to the second starting temperature SonIf yes, the semiconductor refrigeration module 300 is turned off. The second start-up temperature Son is the cooling start temperature of the dry compartment 200, and is a higher temperature. Turning off the semiconductor cooling module 300 when the temperature of the dry compartment 200 is greater than or equal to the second turn-on temperature Son can prevent the thermal load of the dry compartment 200 from being excessively high.
Illustratively, the first boot temperature RonCan be matched with the second starting temperature RonAnd the same or different, and the present invention is not particularly limited thereto.
In step S305, after the semiconductor refrigeration module 300 is turned off for the second predetermined period of time, the controller 600 will determine whether the temperature of the storage compartment 100 is lower than or equal to the first shutdown temperature R againoff。
In step S304, if it is determined that the temperature R of the storage compartment 100 is lower than the second startup temperature, in step S306, the semiconductor refrigeration module 300 continues to be turned on for 30 seconds, and after the 30 seconds, the controller 600 determines whether the temperature R of the storage compartment 100 is lower than the first shutdown temperature R againoff。
