The specific embodiment
Below in conjunction with example shown in the present and accompanying drawing, the present invention will be described in more detail.
As shown in Figure 2, of the present inventionly have a thermostatic refrigerator, include the refrigerating chamber that is provided with temperature sensor 2a 2 of store food and be provided with the refrigerating chamber 4 of temperature sensor 4a; Give the cold air generation systems of refrigerating chamber 2 and refrigerating chamber 4 supply cold air; Cold air is fed to the refrigerating chamber service duct of refrigerating chamber 2 by the cold air generation systems; Cold air is fed to the refrigerating chamber service duct 16 of refrigerating chamber 4 by the cold air generation systems; Refrigerating chamber service duct 16 is provided with heater 30.And refrigerating chamber 2 can be kept the freezing state of food, and the relative refrigerating chamber of actual temperature 4 is low.
Be provided with the temperature sensor 4a that detects refrigerating chamber 4 actual temperatures on the refrigerating chamber 4, and be provided with the temperature sensor 2a that detects refrigerating chamber 2 actual temperatures on the refrigerating chamber 2.Refrigerator passes through by temperature sensor 2a, and 4a detects the temperature of refrigerating chamber 2 and refrigerating chamber 4, controls the air conditioning quantity that is supplied to refrigerating chamber 2 and refrigerating chamber 4.
The cold air that is supplied to refrigerating chamber 2 and refrigerating chamber 4 is to be produced by the evaporimeter in the heat exchange case 10 that is arranged on refrigerating chamber 2 rear ends 12.Carry out heat-exchanged air with evaporimeter 12 surfaces that inside has low-temperature low-pressure refrigerant to flow, become cold gas after, a part is wherein directly sent into refrigerating chamber 2 by Air Blast fan 14, another part cold air then is supplied in the refrigerating chamber 4.
Be fed to the cold air in the refrigerating chamber 4, through the refrigerating chamber passage 16 that communicates with heat exchange case 10 lower ends, the a plurality of cold air delivery outlets that formed by refrigerating chamber passage 16 front ends enter in the refrigerating chamber 4 again, then, after being fed to the cold air portion's circulation within it in refrigerating chamber 2 and the refrigerating chamber 4, return in the heat exchange case 10 that evaporimeter 12 is set through returning pipeline 22,24.The air of getting back in the heat exchange case 10 are after refrigerating chamber 2 and refrigerating chamber 4 circulations, the air that temperature has raise relatively, and these high temperature airs carry out heat exchange with evaporimeter 12 once more, become cold air.Then, these cold air carry out cyclic process as above once more repeatedly.
According to the present invention, cold air is being fed in the way of refrigerating chamber passage 16 by heat exchange case 10.Be provided with heater 30.Heater 30 produces heat by the voltage that is added in two ends, in fact is arranged on the cold air service duct of refrigerating chamber 4.Thus, when heater 30 heat releases, the heating installation of generation is supplied in the refrigerating chamber 4.
Below, in aforesaid refrigerator, the cold air method of supplying of controlling refrigerating chamber 2 and refrigerating chamber 4 temperature is described.
When the actual temperature of refrigerating chamber 2 and refrigerating chamber 4 was all high than design temperature, refrigerator started kind of refrigeration cycle and produces cold air, and cold air is supplied to refrigerating chamber 2 and refrigerating chamber 4.When the actual temperature of refrigerating chamber 2 and refrigerating chamber 4 was all hanged down than design temperature, refrigerator stopped to carry out kind of refrigeration cycle, no longer produces cold air afterwards.Again, the temperature of detection refrigerating chamber 2 and refrigerating chamber 4 is that 4a realizes by described temperature sensor 2a.
