First embodiment, referring to Fig. 2, real-time timepiece chip is the time clock feature element circuit, is used to produce 24 hours clock signals, and clock signal is sent into microprocessor.The utility model be set by the user one weak running time section be first period, for example: time period of user's sleep at 20 (for example from evening to point in evenings 24) or high electricity price time period (for example 22 points from the 6:00 AM to the evening) are set at the weak operational mode time period.Computer operation of the present utility model draws the second period L2, and L2 is the period of a strong operation, defrost period Lx that it comprises and the strong operation period Ly after the defrost period.The time segment length of Lx and Ly be one basic time length the basis on according to weak running time parameter such as segment length, environment temperature, the temperature inside the box carry out corresponding adjusting, factor such as short as weak running time, that environment temperature is low, the temperature inside the box is low will cause the shortening of cold-storage defrost mode time section and strong operational mode time period; Otherwise lengthening.The operation control of L2 period comprises defrost control module and strong operation control module, under the defrost pattern, the energising of cold-storage heater, compressor is out of service, finishes when the data of clock unit show the Lx period, does not perhaps also finish but after cold-storage temperature-sensitive head temperature is higher than certain specific temperature T x to the Lx period, for example Tx=4 ℃, cold-storage defrost pattern finishes, and carries out strong operational mode, finishes to the L2 period.
Refrigerator of the present utility model is operation control system at times, and the period sum of its first, second, third period is 24h.
The idiographic flow of first embodiment of the present utility model is as follows:
Energising brings into operation on the refrigerator, the user sets weak running time of interval, and calculator calculates determines all the other periods, and comparator compares the current time data of real-time clock, judging whether to carry out the L2 period controls (strong operational mode), that is is operation cold-storage defrost pattern earlier; If, start this pattern, at this moment, whether the temperature parameter of microprocessor judges cold-storage temperature-sensitive head is higher than temperature T x (Tx can be set at 4 ℃), is then to finish the defrost step to carry out strong operating procedure, finishes to carry out strong operating procedure otherwise continue to move to the Lx period again.Get back to the step of determining the weak operation period after executing strong operating procedure.
If relatively the result of real-time clock is not a cold-storage defrost pattern, then more whether be in weak operation period L1 again, if, move to the L1 period by weak operational mode and finishes, get back to and determine the weak step of moving the period; If not, then move to the L3 period and finish, return the step of determining the weak operation period by general mode.Carry out the 3rd o'clock paragraph controller in the L3 period and control, specifically control according to the following steps: the detecting sensor temperature is also pressed the start-stop that temperature is controlled compressor; Wherein the compressor turn-on temperature is: the temperature parameter of refrigeration sensor is higher than t31+ Δ t0, and freezing sensor temperature parameter is higher than t32+ Δ t0; The compressor shutdown temperature is: the temperature parameter of refrigeration sensor is lower than t31, and freezing sensor temperature parameter is lower than t32.
In carrying out the defrost step, temperature of refrigerating chamber is higher than design temperature T1 and the regenerator temperature is lower than design temperature T1 if detect, then fan operation (if be provided with air door then air door is also opened), otherwise fan is out of service.
Under strong operational mode, can control by following rule: compressor a period of time L01 that starts shooting continuously, stop a period of time L02, wherein L01 is greater than L02.Also can control according to the following steps: disconnect the cold-storage defrosting device, start compressor, the detecting sensor temperature is also pressed the start-stop that temperature is controlled compressor; Wherein the compressor shutdown temperature is: the temperature parameter of refrigeration sensor is lower than t21 (specifically can be than low 2 ℃ of refrigeration set temperature value T1), and freezing sensor temperature parameter is lower than t22 (specifically can be than low 6 ℃ of freezing set temperature value T2), and cold-storage sensor temperature parameter is lower than T23 (for example T23=-24 ℃); Compressor turn-on temperature condition is: the temperature parameter of refrigeration sensor is higher than t21+ Δ t0, and freezing sensor temperature parameter is higher than t22+ Δ t0.2 ℃ of Δ t0 values.
In carrying out strong operating procedure, be higher than design temperature T1 and cold-storage sensor temperature near desired value T23 (for example T23=-24 ℃) if detect temperature of refrigerating chamber, the fan that then blows in to the refrigerating chamber released cold quantity, otherwise is closed fan.
Under the weak operational mode, (t11 is higher 2 ℃ than refrigerating chamber design temperature when the refrigerated storage temperature parameter is higher than t11+ Δ t0,2 ℃ of Δ t0 values) and the temperature parameter of cold-storage sensor be higher than T13 (can value 0 ℃), compressor start when perhaps freezing sensor temperature parameter is higher than t12+ Δ t0 (t12 is specifically high 6 ℃ than freezing set temperature value T2); When temperature of refrigerating chamber is lower than t11, and freezer temperature compressor shutdown when being lower than t12.
Be higher than T1+ Δ t1 if detect temperature of refrigerating chamber, the fan that then blows in (having air door will open air door) is lower than T1-Δ t1 if detect temperature of refrigerating chamber, then closes fan (or air door), but 1 ℃ of the concrete value of Δ t1.
In the value of each temperature parameter, must satisfy t11>T1 〉=t31>t21; T12>T2 〉=t32>t22; Tx>T13>T23.
