The specific embodiment
As shown in Figure 1, cold accumulation refrigerator of the present utility model comprises refrigeration system, holds electric power system, cold accumulation system and casing, and casing comprises inner container of icebox, refrigerating chamber and refrigerating chamber, and refrigeration system includes direct current compressor 6.
Holding electric power system comprises power input plug 1, rectifier 20, switch controller 5 and is serially connected in charging device 2, change-over switch 3 and the electrical storage device 4 that holds electric supply installation successively.Be connected power input plug 1 after the input parallel connection of the input of charging device 2 as the input that holds electric supply installation and rectifier 20, the output that holds electric supply installation is electrically connected with switch controller 5 respectively with the output of rectifier 20, and the output of switch controller 5 is electrically connected with the input of direct current compressor 6.Hold electric power system and be arranged on the top of refrigerator, the control panel that holds electric power system is positioned at the positive front portion of holding electric power system.Wherein, described change-over switch 3 is a time switch, and described switch controller 5 is the temperature control selector switch.
Cold accumulation system comprises refrigerating chamber cold storage box and refrigerating chamber cold storage box, as shown in Figure 2, refrigerating chamber cold storage box 12,13,14,15,16 be arranged at the corresponding inner container of icebox in refrigerator evaporator position on.As shown in Figure 3, refrigerating chamber cold storage box 17,18,19,20,21 is arranged on the freezer evaporator.The refrigerating chamber cold storage box can be arranged on and corresponding inner container of icebox surface, refrigerator evaporator position, also can be arranged on the back side of this inner container of icebox.
Refrigeration system comprises that direct current compressor 6, condenser 7, capillary 8, freezer evaporator 9, refrigerator evaporator 10, vapour divide device 11 and refrigeration pipe etc.The suction of direct current compressor 6, exhaust outlet divide device 11 and condenser 7 to be connected by refrigeration pipe with vapour respectively, vapour divides device 11 to connect with refrigerator evaporator 10 and freezer evaporator 9 by refrigeration pipe again, is being connected capillary 8 between freezer evaporator 9 and condenser 7.The refrigeration working medium of described refrigeration pipe becomes the HTHP gaseous working medium and flows to condenser 7 after direct current compressor 6 compressions, in condenser 7, be cooled to liquid state, the throttling step-down becomes the low-temp low-pressure damp steam in capillary 8, in freezer evaporator and refrigerator evaporator, become superheated vapor after the heat absorption and suck direct current compressor, thereby finish a kind of refrigeration cycle.
In the low power consumption period, switch controller 5 keeps the off-state of electrical storage device 4 and direct current compressor 6.When the temperature in the refrigerator was higher than setting value, switch controller 5 was communicated with rectifier 20 and direct current compressor 6, directly supplies with the refrigerator electricity consumption by electrical network, thus the refrigeration of realization, and cold storage box 12 to 21 is accumulated cold simultaneously.When the temperature in the refrigerator reached or be lower than setting value, switch controller 5 stopped to direct current compressor 6 power supplies.Certainly in the low power consumption period, hold electric supply installation and also work simultaneously, the electrical network electricity is stored in the electrical storage device 4.
In the peak of power consumption period, switch controller 5 eliminating rectifiers 20 are connected with direct current compressor 6, just stop with the electrical network electricity directly for the refrigerator power supply, by cold storage box 12 to 21 released cold quantities.When the cold of cold storage box 12 to 21 releases was not enough to satisfy the temperature requirement of refrigerator, promptly when the temperature in the refrigerator was higher than setting value, switch controller 5 was communicated with electrical storage device 4 and direct current compressors 6, was the refrigerator power supply by electrical storage device 4.When the temperature in the refrigerator reached or be lower than setting value, switch controller 5 stopped to direct current compressor 6 power supplies.
Certainly, the utility model includes but not limited to present embodiment, also can be wholely set with refrigerator evaporator as the refrigerating chamber cold storage box, and refrigerating chamber also can be wholely set with freezer evaporator with cold storage box.Such conversion all drops within the protection domain of the present utility model.
