It is provided with the first compartment 2, second compartment 3.First compartment 2 and second compartment 3 side by side and are spaced apart.On cabinet body 1 or it is arranged
Have for the refrigeration system 6 to 3 cooling supply of the first compartment 2 and second compartment.It is provided on the front face of cabinet body 1 for being set for user
Determine the first temperature-controlled member 4 of 2 operating temperature of the first compartment and the second temperature control for setting 3 operating temperature of second compartment for user
Component 5.
As shown in Fig. 2, refrigeration system 6 includes the first temperature sensor 61, second temperature sensor 62, the first evaporator
64, control device 63, the first capillary 65, the second evaporator 66, the second capillary 67, condenser 68, filter 69, compressor
610。
First temperature sensor 61 is used to detect the temperature inside the first compartment 2, and second temperature sensor 62 is for detecting
Temperature inside second compartment 3.First temperature sensor 61 and second temperature sensor 62 connect with 63 phase signals of control device
It connects and the first temperature sensor 61 and second temperature sensor 62 is enabled to be detected that temperature signal is transferred to control device
63.First temperature-controlled member 4, the second temperature-controlled member 5 also connect with signal with control device 63 respectively, i.e. 4 He of the first temperature-controlled member
The selected each room temperature angle value adjusted of user can be fed back to control device 63 by the second temperature-controlled member 5, and control device 63 can
It is worked according to this temperature controlled refrigerating system.
Compressor 610, condenser 68, filter 69, the first capillary 65 and the first evaporator 64 are sequentially communicated composition
First refrigeration cycle is provided in the first refrigeration cycle and controls the first refrigeration cycle access and open circuit
First solenoid valve 611, the first solenoid valve 611 are located between filter 69 and the first capillary 65.Compressor 610, condenser 68,
Filter 69, the second capillary 67 and the second evaporator 66, which are sequentially communicated, constitutes the second refrigeration cycle, in the second refrigeration
The second solenoid valve 612 for controlling the second refrigeration cycle access and open circuit, second solenoid valve 612 are provided in circulation loop
Between filter 69 and the second capillary 65.First solenoid valve 611 and second solenoid valve 612 are phased with control device 63
System connection control device 63 to control the first solenoid valve 611 and second solenoid valve 612 to open and close, to realize the
One, the access of two refrigeration cycles and open circuit.
In order to facilitate the work of control device 63, it is provided in control device 63 for the first refrigeration cycle and
Two refrigeration cycles are continuously in the timing module 613 that channel status carries out timing, this timing module 613 enables to control
Device 631 requires to control each refrigeration cycle work according to setting time.2 He of the first compartment should be preset in control device 63
Between second 3 Room initializations sequences and it is initial when the first and second refrigeration cycle in each circuit single when continuing working longest
Between；As in this example, can preset the first compartment 2 in control device 63 is the compartment preferably to freeze, between the first compartment 2 and second
It is 0.5 hour that 3 single of room, which continues working maximum time, and control device 63 requires to work according to the default control.
The process of refrigerastion of the refrigerator is described below:
Before refrigerator 100 brings into operation, the first compartment 2 and second is set separately using the first and second temperature-controlled member 4 and 5 in user
The operating temperature of compartment 3, control device 63 control each component according to preset operating temperature requirements and work；First compartment 2 is preferential
Start to be freezed, i.e., control device 63 controls the first solenoid valve 611 opening, second solenoid valve 612 is closed, in the first capillary 65
Refrigerant be switched on to carry out refrigerant conversion, the perforation of the first refrigeration cycle freezes to the first compartment 2, first
Actual temperature information in first compartment 2 is transferred to control device 63 in real time by temperature sensor 61, when in control device 63
When timing module 631 show that the lasting cooling time of the first refrigeration cycle reaches 0.5h, first electricity of the control of control device 63
Magnet valve 611 is closed, and the stopping of the first compartment 2 is freezed, and at the same time, control device 63 controls second solenoid valve 612 and opens, and second
The channel of capillary 67 penetrates through, and the refrigerant in the second capillary 67 is switched on to carry out refrigerant conversion, and the second refrigeration is followed
Loop back path starts to carry out refrigeration work, and the beginning of second compartment 3 is freezed, and when the timing module 631 in control device 63 obtains
When the lasting cooling time of the second refrigeration cycle reaches 0.5h out, refrigerant flow direction is converted again, the first solenoid valve 611
Be opened, second solenoid valve 612 is closed, and returns to the situation that the first refrigeration cycle freezes, the first compartment 2 continues quilt
Refrigeration, when the timing module 631 in control device 63 show that the lasting cooling time of the first refrigeration cycle reaches 0.5h,
Alternately freeze again；In the first and second compartment, if wherein a room temperature reaches the operating temperature of setting, first,
Two solenoid valves will not reconvert, refrigerant, which fully enters, not to freeze up to another compartment of set temperature, the temperature to the compartment
When degree also reaches set temperature, compressor is then shut down into standby mode；With the operation of refrigerator, when a compartment in refrigerator
Temperature recovery feeds back to control dress to the operating temperature upper limit of setting, i.e. the first temperature sensor 61 or second temperature sensor 62
Set 63 corresponding compartment temperature be higher than setting operating temperature when, compressor restarts work, and the solenoid valve of corresponding compartment is opened
So that corresponding capillary perforation is to carry out refrigerant conversion until the compartment temperature is restored within the scope of set temperature；With
The operation of refrigerator, when two compartment temperatures in refrigerator go back up to the upper limit of set temperature, i.e. the first temperature sensor 61 simultaneously
When the corresponding compartment temperature for feeding back to control device 63 with second temperature sensor 62 is above corresponding set temperature, compressor
Restart work, freezes according to another compartment is transformed into after the first compartment 2 preferentially refrigeration, continuous operation 0.5h until two room temperatures
Degree is all satisfied condition.
This case solves in existing refrigerator, and refrigeration system is different with Leng Dong, volume of refrigerating chamber due to the difference of environment temperature
Caused cooling capacity distribution is unbalanced.Any conversion of freezing and refrigeration may be implemented in the double temperature double control refrigerator of this programme completely, different
Temperature in compartment can be adjusted freely.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by spirit, should be covered by the protection scope of the present invention.
