Referring to Fig. 1, traditional computer temperature control refrigerator control system generally has with the lower part: the temperature sensor that detects refrigerating chamber, refrigerating chamber, evaporimeter, environment temperature, the magnetic valve even load parts of compressor, defrosting heater, control refrigerant flow direction, memory, with the temperature-sensitive head main control unit that communication is connected with load component, main control unit generally has element circuits such as microprocessor and power supply conversion.Refrigerator of the present invention is provided with regenerator, and between regenerator and refrigerating chamber, the air channel is set, and fan or other air circulation device are set on the air channel, make in needs, the cold that stores up on regenerator can take refrigerating chamber to by the fan operation, to keep the storage temperature of refrigerating chamber.Can establish air door switch on the air channel, also can not establish.Heater or other defrosting device are set on the regenerator, and purpose is the heat-transfer effect that guarantees regenerator.Except to refrigerating chamber refrigerating chamber refrigeration, simultaneously regenerator is freezed during the freezer compressor operation.The cold-storage temperature-sensitive head is experienced the temperature of regenerator, the cold-storage heater is then when needed to regenerator heating defrost, the present invention increased clock unit (that is being real-time timepiece chip) on the basis of traditional computer temperature control refrigerator, corresponding to the control circuits of different periods with corresponding to the operation display interface of functions expanding, the operation display interface comprises input unit, display unit, but functional parameters such as input period setting, storage temperature setting on the user interface.Importantly: control system of the present invention also comprises the calculator that first a period L1 who presets according to user input or producer and temperature sensor data operation go out the second period L2, the 3rd period L3; In described three periods, carry out first, second, third o'clock paragraph controller of different operational modes; One of them of paragraph controller carried out the comparator of refrigerator operation control when being used for described clock unit data and period relatively and by described three.Launch to illustrate two implementation methods of the present invention in detail below in conjunction with Fig. 2 and Fig. 3.
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 present invention 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 invention 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 invention 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 invention 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.
Second implementation method is to change on first implementation method, sometimes electric network fault takes place in the daily life and cause power failure, if constantly drop in real time the weak operation period when sending a telegram here, then refrigerator is by weak operational mode control again, so, will have influence on depositing of food.Second implementation method can address the above problem.Referring to Fig. 3, energising brings into operation on the refrigerator, and 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, judges whether to carry out the L2 period control (operational mode by force); If not, then press the general mode operation, enter the L1 period, should enter cold-storage defrost pattern up to real-time clock.System operation this moment cold-storage defrost pattern, defrost pattern finish the back and move to the L2 period by strong operational mode and finish.The L2 period finishes the back at once by weak operational mode control.All the other control steps are identical with first implementation method, are not described in detail in this.
