Detailed description of the invention
By describing technology contents, the structural feature of invention in detail, being reached purpose and effect, below in conjunction with embodiment also
Accompanying drawing is coordinated to be described in detail.
Refrigerator 100 as shown in Figure 1, this refrigerator be double between room refrigerator, there is the cabinet 1 of a tetragonal body shape, on cabinet 1
It is provided with first room 2, second compartment 3.First room 2 and second compartment 3 side by side and are spaced apart.Still arrange on cabinet 1
Have for first room 2 and the refrigeration system 6 of second compartment 3 cooling.It is provided with on the front face of cabinet 1 for setting for user
Determine the first temperature-controlled member 4 of first room 2 operating temperature and for setting the second temperature control of second compartment 3 operating temperature for user
Parts 5.
As in figure 2 it is shown, refrigeration system 6 includes first temperature sensor the 61, second temperature sensor the 62, first vaporizer
64, device the 63, first capillary tube the 65, second vaporizer the 66, second capillary tube 67, condenser 68, filter 69, compressor are controlled
610。
First temperature sensor 61 is for detecting the temperature within first room 2, and the second temperature sensor 62 is used for detecting
Temperature within second compartment 3.First temperature sensor 61 and the second temperature sensor 62 are all with control device 63 phase signals even
Connect so that the first temperature sensor 61 and the second temperature sensor 62 can be detected that temperature signal is transferred to control device
63.First temperature-controlled member the 4, second temperature-controlled member 5 connects with signal with control device 63 the most respectively, the i.e. first temperature-controlled member 4 He
User can be selected each room temperature angle value of regulation and feed back to control device 63 by the second temperature-controlled member 5, and controlling device 63 can
Work according to this temperature controlled refrigerating system.
Compressor 610, condenser 68, filter the 69, first capillary tube 65 and the first vaporizer 64 are sequentially communicated composition
First refrigeration cycle, is provided with in the first refrigeration cycle and controls this first refrigeration cycle path and open circuit
First electromagnetic valve 611, the first electromagnetic valve 611 is between filter 69 and the first capillary tube 65.Compressor 610, condenser 68,
Filter the 69, second capillary tube 67 and the second vaporizer 66 are sequentially communicated composition the second refrigeration cycle, in the second refrigeration
Closed circuit is provided with the second electromagnetic valve 612 controlling this second refrigeration cycle path with open circuit, the second electromagnetic valve 612
Between filter 69 and the second capillary tube 65.First electromagnetic valve 611 and the second electromagnetic valve 612 are all phased with control device 63
Connection processed makes to control device 63 can control the first electromagnetic valve 611 and the second electromagnetic valve 612 opens and closes, thus realizes the
One, the path of two refrigeration cycles and open circuit.
Control the work of device 63 for convenience, control to be provided with in device 63 for the first refrigeration cycle and the
Two refrigeration cycles are continuously in channel status and carry out the timing module 613 of timing, and this timing module 613 enables to control
Device 631 controls the work of each refrigeration cycle according to setting time requirement.Control device 63 should preset first room 2 He
Between second 3 Room initializations orders and initial time first and second refrigeration cycle in each loop single continuous firing the longest time
Between；As in this example, first room 2 can be preset for room between preferably freezing, between first room 2 and second controlling device 63
Room 3 single continuous firing maximum time is 0.5 hour, controls device 63 and requires to be operated according to this default control.
The process of refrigerastion of this refrigerator once described below:
Before refrigerator 100 brings into operation, user utilizes first and second temperature-controlled member 4 and 5 to set room 2 and second compartment 3 between first respectively
Operating temperature, control device 63 and control each component working according to default operating temperature requirements；First room 2 preferentially start by
Refrigeration, i.e. controls device 63 and controls that the first electromagnetic valve 611 is opened, the second electromagnetic valve 612 cuts out, the refrigeration in the first capillary tube 65
Agent is switched on thus carries out cold-producing medium conversion, and the first refrigeration cycle is through to freeze to first room 2, and the first temperature passes
Sensor 61 is transferred to the actual temperature information in first room 2 to control device 63 in real time, when the timing mould controlled in device 63
Block 631 draws when the lasting cooling time of the first refrigeration cycle reaches 0.5h, controls device 63 and controls the first electromagnetic valve 611
Closing, first room 2 stops being freezed, and meanwhile, control device 63 controls the second electromagnetic valve 612 and opens, the second capillary tube
The passage of 67 is through, and the cold-producing medium in the second capillary tube 67 is switched on thus carries out cold-producing medium conversion, the second refrigeration cycle
Proceeding by refrigeration work, second compartment 3 starts to be freezed, and when the timing module 631 controlled in device 63 draws second
When the lasting cooling time of refrigeration cycle reaches 0.5h, again being changed by refrigerant flow direction, the first electromagnetic valve 611 is beaten
Open, the second electromagnetic valve 612 is closed, and returns to the situation that the first refrigeration cycle carries out freezing, and first room 2 continues to be made
Cold, when the timing module 631 controlled in device 63 show that the lasting cooling time of the first refrigeration cycle reaches 0.5h, then
Secondary alternately freeze；In first and second room, if wherein an indoor temperature reaches the operating temperature set, first and second
Electromagnetic valve will not reconvert, cold-producing medium fully enters and does not reaches another room of design temperature and freeze, treats the temperature of this room
When also reaching design temperature, entrance holding state then shut down by compressor；Along with the operation of refrigerator, when a room temperature in refrigerator
Degree goes back up to the operating temperature upper limit set, and the i.e. first temperature sensor 61 or the second temperature sensor 62 feed back to control device
When the corresponding compartment temperature of 63 is higher than the operating temperature set, compressor restarts work, corresponding between the electromagnetic valve of room be opened and make
Corresponding capillary tube is through thus carry out cold-producing medium conversion until in the range of this compartment temperature returns to design temperature；Along with cold
The operation of cabinet, when two compartment temperatures in refrigerator go back up to the upper limit of design temperature, the i.e. first temperature sensor 61 He simultaneously
Second temperature sensor 62 feeds back to and controls the corresponding compartment temperature of device 63 when being above corresponding design temperature, weight of compressor
Open work, preferentially freeze according to first room 2, continuously run 0.5h after be transformed into another room refrigeration until two compartment temperatures
It is satisfied by condition.
This case, solves in existing refrigerator, refrigeration system due to ambient temperature difference with freezing, volume of refrigerating chamber is different
The cold distribution caused is unbalanced.The double temperature double control refrigerator of this programme can realize any conversion of freezing and refrigeration completely, different
Between temperature in room can freely regulate.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
