Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described.
As shown in Figure 1, the low-power consumption temperature control system of portable refrigerator comprises that single-chip microcomputer 4, temperature and status display circuit 5, temperature collecting device 6, temperature arrange device 7, MOSFET pipe switch 8, semiconductor cooler 9, lithium battery 3, solar panel 1 and lithium cell charging control circuit 2; Single-chip microcomputer arranges device 7 with temperature collecting device 6, temperature respectively and is connected with MOSFET pipe switch 8; MOSFET pipe switch 8 is connected with semiconductor cooler 9; MOSFET pipe switch 8, single-chip microcomputer 4 are connected with lithium battery 2 respectively.Lithium cell charging control circuit one end is connected with solar panel, and the other end is connected with lithium battery.Temperature collecting device is for being arranged on respectively four 1-wire temperature sensors of refrigerator surrounding.Lithium battery is the poly-lithium battery of high power capacity, and single-chip microcomputer is 8 pin single-chip microcomputers of super low-power consumption.
Its operation principle is: solar panel 1 gives lithium battery 2 chargings, lithium battery 2 is given semiconductor cooler 9, single-chip microcomputer 4 power supplies, single-chip microcomputer is by controlling the Push And Release that cut-offs to control semiconductor cooler of MOSFET pipe, to control refrigeration, the heat insulation work of semiconductor cooler, reach the super low-power consumption requirement.Single-chip microcomputer 4 is controlled the temperature that temperature collecting device gathers portable refrigerator, in order to know more accurately the actual temperature of portable mini-bar, temperature collecting device 6 adopts the intelligent temperature sensor of 4 monobus, the intelligent temperature sensor of 4 monobus is arranged on respectively the surrounding of mini-bar casing, four tunnel temperature that temperature collecting device will gather send to super low power consuming single chip processor 4, after four road temperature values that super low power consuming single chip processor 4 will receive are averaged, obtain actual temperature; By temperature, device 7 is set stopping cryogenic temperature TL and beginning cryogenic temperature TH of portable mini-bar is set; When actual temperature during greater than TH, super low power consuming single chip processor 4 is controlled MOSFET pipe switch 8, make its conducting to semiconductor cooler 9 power supplies, portable mini-bar begins refrigeration, and when temperature was reduced to TL, super low power consuming single chip processor 4 was controlled 8 cut-offs of MOSFET pipe switch, stop to semiconductor cooler 9 power supplies, portable mini-bar begins insulation, until temperature continues refrigeration when rising to TH again, and so periodic duty; Super low power consuming single chip processor 4 controls temperature and status display circuit 5 shows actual temperature, duty and the TL of portable mini-bar and the value of TH in real time.
This low-power consumption temperature control system, simple in structure, reliable and stable, can well solve portable energy-saving mini-bar power problems, make mini-bar reach the refrigeration of expection, the effect that heats or be incubated with minimum power consumption.
