Specific embodiment
To describe technology contents, structural features, institute's reached purpose and effect of utility model in detail, below in conjunction with enforcement
Example simultaneously coordinates accompanying drawing to be described in detail.
Refrigerator 100 as shown in Figure 1, the refrigerator be separate room reach in freezer, the cabinet 1 with a tetragonal body shape, cabinet 1
On be provided with a refrigerating chamber 2 and for the refrigeration system 3 of the cooling of refrigerating chamber 2.It is provided with the front face of cabinet 1 for supplying
User sets the temperature-controlled member 4 of the operating temperature of refrigerating chamber 2.
As shown in Fig. 2 being provided with the temperature sensor 5 for detecting the temperature of refrigerating chamber 2, temperature sensor 5 in refrigerating chamber 2
Connect with signal with control device 6, temperature-controlled member 4 also connects with signal with control device 6.A use is provided with control device 6
In the design temperature for judging refrigerating chamber（The temperature that i.e. user sets in temperature-controlled member 4）With actual temperature（That is temperature sensor 5 again
The real time temperature of transmission）The temperature difference judge module 7 of difference.
Refrigeration system 3 includes vaporizer 8, the first capillary tube 9, the second capillary tube 10, condenser 11, filter 12, compression
Machine 13 and shunt valve 14, the capillary tube 9 of shunt valve 14 and first is in parallel setting, the first capillary tube 9 and the phase of the second capillary tube 10
It is arranged in series, an electromagnetic valve 15 is provided with shunt valve 14, electromagnetic valve 15 connects with signal with control device 6.Electromagnetic valve 6 has
Open working condition and close working condition；Working condition is opened when electromagnetic valve 15 is located at, the first capillary tube 9 and shunt valve 14 are equal
It is connected with the second capillary tube 10；When electromagnetic valve 15 is located at closed mode, the first capillary tube 9 is connected with the second capillary tube 10
Logical, shunt valve 14 is cut off and not insertion by electromagnetic valve 15.
The process of refrigerastion of the refrigerator 100 is described below：Before refrigerator 100 brings into operation, user is set using temperature-controlled member 4
Determine the cryogenic temperature of refrigerating chamber 2, control device 6 requires each component working of control, temperature sensor 5 according to default cryogenic temperature
The actual temperature of the refrigerating chamber 2 for being detected is transferred to control device 6, and control device 6 is using temperature difference judge module 7 thereon
Judge the difference of the actual temperature in refrigerating chamber 2 and the freezing of setting, control device 6 determines electromagnetic valve 15 according to this difference
Switch, fiducial temperature threshold value in control device 6, when the temperature difference that temperature difference judge module 7 judges is more than temperature difference threshold, control device
6 control electromagnetic valves 15 are opened, the insertion of shunt valve 14, now, the shunt valve 14 that most cold-producing mediums are located by electromagnetic valve 15
With the second capillary tube 10（Pressure reduction is less）, only fraction cold-producing medium passes sequentially through the first capillary tube 9, and current refrigerator 100 is entered
The cryogenic temperature of load meeting fast approaching setting in fast-refrigerating pattern, cabinet.When temperature difference judge module 7 judge the temperature difference less than etc.
When temperature difference threshold, refrigerating chamber is now illustrated already close to design temperature, the control electromagnetic valve 15 of control device 6 is closed, shunt valve
14 are cut off, and now cold-producing medium all passes sequentially through the first capillary tube 9 and the second capillary tube 10, pressure reduction increase, evaporating temperature drop
Low, after refrigeration duty is also reduced, now refrigeration system 3 is needed into normal Deep-Frozen kind of refrigeration cycle with the refrigeration for maintaining refrigerating chamber
Ask.
Therefore, the refrigerator of this case, in start substantial amounts of load is put into（Frozen food）When, refrigeration system can be using inspection automatically
The difference of the temperature inside the box and design temperature is surveyed, ordering about refrigeration system will be cold so as to substantially increase into " quick cooling " state
The rate of cooling of jelly food；And when the temperature difference is less than given threshold, refrigeration system is ordered about again and is followed into normal Deep-Frozen refrigeration
The ring temperature recovery speed indoor to slow down freezing so that refrigerating chamber remains cryogenic temperature.The refrigeration system of this programme refrigerator
System, can reduce the on-off frequency of compressor, save energy consumption.
The refrigerator of this case both can be used on the common refrigerator of AC-powered, it is also possible to used in by battery-driven straight
On stream refrigerator, and by battery-driven refrigerator, after once charging the longer working time can be obtained.
