A temperature sensor (not shown in the figure) is arranged in the cold storage box 4, and a pressure sensor (not shown in the figure) is arranged on the floating bottom plate 6.
The working process is as follows:
firstly, when fresh products are not put in the storage space 11, the pressure sensor does not detect a heavy object, and the semiconductor refrigeration plate 2 is in a state of stopping working.
Secondly, when putting into the fresh produce in the parking space 11, pressure sensor detect the heavy object and send out the signal, this moment, electro-magnet 7 and refrigeration board 2 according to temperature sensor's feedback signal and action.
2.1 when the temperature that temperature sensor detected reaches the settlement temperature, electro-magnet 7 lose the electricity, floating bottom plate 6 compresses tightly under the effect of spring 611 on the lower terminal surface of cold-storage box 4, and semiconductor refrigeration board 2 is in the state of stopping working. At this time, the transition plate is in a state as shown in fig. 10, that is, the heat transfer plate 52 and the second fin 422 are in a dislocated state, and the cooling capacity in the cold storage tank 4 is blocked therein, so that the cooling capacity is not lost by the heat transfer through the second fin 422. At this time, the cold storage box 4 releases cold energy into the storage space 11 through the second heat dissipation fins, so as to maintain the temperature in the storage space 11 and ensure that the fresh products in the storage space are in a low-temperature state.
2.2 when the temperature detected by the temperature sensor does not reach the set temperature (namely is higher than the set temperature by a certain temperature range), the electromagnet 7 is electrified, and meanwhile, the semiconductor refrigeration plate 2 starts to work. At this time, the spring 611 is compressed, and the floating bottom plate 6 is in the lower limit position, i.e., the state shown in fig. 11. The cold energy sent by the semiconductor refrigeration plate 2 is transmitted to the second heat dissipation plate through the heat transfer plate 52, one part of the cold energy in the second heat dissipation plate directly enters the storage space 11, the other part of the cold energy enters the cold storage box 4 to be stored, the temperature in the cold storage box 4 is reduced until the temperature detected by the temperature sensor reaches the set temperature, the electromagnet 7 is de-energized, the floating bottom plate 6 is tightly pressed on the lower end surface of the cold storage box 4 under the action of the spring 611, and the semiconductor refrigeration plate 2 stops working.
