Refrigerating chamber is divided into multiple storage spaces by rack component 320.One of which preferred structure is：Rack component 320 include at least one horizontally disposed dividing plate, and refrigerating chamber is vertically divided into multiple storage spaces.In fig. 2, Refrigerating chamber is divided into the first storage space 341, the second storage space 342, the 3rd storage space 343 by rack component 320. In other embodiments of the present invention, the quantity of dividing plate quantity and storage space in rack component 320 can be according to ice The volume and requirement of case are configured in advance.

Device for measuring volume 330 includes at least one detection components.Detection components are arranged in refrigerating chamber, for sending light Signal and detection optical signal.These optical signals include visible ray and infrared light.Each detection components comprise at least：Visible ray Source, infrared light supply, light sensitive device.Visible light source is configured to send visible ray to cooling compartment.Infrared light supply is configured to storage Infrared light is sent inside thing compartment.Light sensitive device is configured to detect the visual intensity of detection components position and infrared light intensity Degree.The quantity of detection components can be determined according to the volume and structure of refrigerating chamber.In fig. 2 it is shown that volume measurement Device 330 is respectively arranged with a detection group in the first storage space 341, the second storage space 342, the 3rd storage space 343 Part.

With the change using size using volume of refrigerating chamber, it is seen that the reflection of light and infrared light in storage space Changed with situation about blocking, and the propagation characteristic of visible ray and infrared light is there is also difference, by the summary of inventor And test, the rule that visual intensity and infrared luminous intensity change with the change using volume is summed up, so as to utilize optics Principle realizes the detection of refrigerator volume.

Other visible above light source can also substitute using the lighting source of refrigerating chamber, thus the lighting source except for User provides the light source that the visible ray needed for volume calculations is also used as outside illumination.In the case, lighting source Brightness needs the requirement for reaching volume measurement.

When detection components are multiple, multiple detection components are distributed on the inside of the perisporium of refrigerating chamber, and require to be placed in week The line of the central point of any two detection components on wall same plane and the folder of other planes intersected in perisporium with plane Angle is not 0 degree or 90 degree；The line of the central point for any two detection components being arranged in perisporium Different Plane and level The angle of face or perpendicular is not 0 degree or 90 degree.

Step S1308, the required fast-refrigerating run time of each storage space is subtracted to the time consumed, obtained The remaining fast-refrigerating run time of each storage space.Because above control flow is that circulation performs, therefore, the above has disappeared The time of consumption is generally the cycle of secondary program execution.So as to which calculation process can be：TH1=TH1-T；TH2=TH2-T；TH3 =TH3-T, wherein T are the cycles of the program execution flow of the whole refrigerating chamber control refrigerating chamber control shown in Fig. 6, it is possible to understand that Perform step S1308 twice to be adjacent, between time for consuming.

Step S1310, judge whether to meet RT<R-off, if performing step S1312, step S1322 is performed if not, with Ensure quick reduction refrigerating chamber bulk temperature.

Step S1312, judges whether RT<(R-off-n), if performing step S1312 after air door is closed, perform if not Step S1314, that is, judge that refrigeration room environmental mean temperature RT reaches n degrees Celsius already below R-off, wherein n is default Constant, the step is performed to prevent that temperature of refrigerating chamber is too low, the second refrigeration closing temperature threshold value of (R-off-n) i.e. above.

Step S1314, determines the refrigeration mark of the first storage space, can specifically include judging that TH1 is less than or equal to 0, If so, gate1 is set off, and TH1 is reset；If it is not, gate1 is arranged to start；

Step S1316, determines the refrigeration mark of the second storage space, can specifically include judging that TH2 is less than or equal to 0, If so, gate2 is set off, and TH2 is reset；If it is not, gate2 is arranged to start；

Step S1318, determines the refrigeration mark of the 3rd storage space, can specifically include judging that TH3 is less than or equal to 0, If so, gate3 is set off, and TH3 is reset；If it is not, gate3 is arranged to start.

Above step S1314 to step S1318 execution sequence can overturn, that is, when performing, each storage space The determination order for mark of freezing can be with unrestricted；

Step S1320, the running status of branch air-supply arrangement is determined according to gate1, gate2, gate3 state；

Step S1322, return to refrigerating chamber refrigeration control flow.
