Described casing 10 be further arranged below Machine Room 50, include compressor 51 in described Machine Room 50, described compressor 51 circulates in cold-producing medium pipeline inside and outside described refrigerator 1 in order to controlling。Described refrigerator 1 also includes maintaining the refrigeration system of temperature constant in refrigerator 1, described refrigeration system includes described compressor 51, be embedded in described foaming layer 12 vaporizer 13 and be arranged on the air door 14 on freezing inner bag 40 rear wall, thus the cold air through described vaporizer 13 can enter described freezing compartment 41 by described air door 14, to reduce the temperature in described freezing compartment 41。
Fig. 1 has indicated air door 14 and has been opened on freezing inner bag 40, it is not limited to be positioned only on freezing inner bag 40, the rear wall of described cold preservation inner bag 20 and alternating temperature inner bag 30 is also equipped with described air door (not shown), thus the cold air through described vaporizer 13 can pass through the described air door described refrigerator room 21 of entrance and temperature-changing chamber 31, to reduce the temperature in described refrigerator room 21 and temperature-changing chamber 31。It is also respectively provided with temperature sensor 15, respectively the temperature in described refrigerator room 21, temperature-changing chamber 31 and freezing compartment 41 to be monitored in real time in described refrigerator room 21, temperature-changing chamber 31 and freezing compartment 41。
Described refrigerator 1 farther includes the cold compensation device (not shown) being separately positioned in described refrigerator room 21, temperature-changing chamber 31 and freezing compartment 41, certainly, described cold compensation device is provided separately within one of them indoor also dependent on needs, may also be arranged between two of which indoor, in this not restriction。Described cold compensation device includes detection system, computing system and control system。Described detection system is for detecting volume and/or the quality of high temperature load when refrigerator 1 is stored in high temperature load (such as high temperature food)；Described computing system carries out heat Calculation for volume and/or the quality according to high temperature load；Described control system is predicted the cold required for reducing load temperature for the result of calculation according to computing system and controls the working time of refrigeration system (mainly compressor 51) in advance, to compensation and the control carrying out cold indoor between refrigerator 1, to reach to reduce the purpose of temperature fluctuation。The volume of load and/or quality are more big, and the working time of refrigeration system is more long, and it is more many that cold supplements；The volume of load and/or quality are more little, and the working time of refrigeration system is more short, and it is more few that cold supplements。Described detection system, computing system, control system omnidistance action be all automatically performed, it is not necessary to manual operation。
Described detection system include being placed on 1 room of refrigerator (can be refrigerator room 21, can be temperature-changing chamber 31, be alternatively freezing compartment 41, not restriction herein, directly be referred to as with a room) in pattern recognition device, automatically the volume of high temperature load and/or quality are identified detection, the type of high temperature load can also be identified by described pattern recognition device simultaneously automatically, using as controlling the auxiliary reference that system controls the working time of refrigeration system。Certainly, described detection system may also comprise other Intelligent Recognition means that volume of high temperature load and/or quality can be identified detection automatically, it is not limited in pattern recognition device, such as: gravity sensor or light transmittance identification or bar code or RF identification (RFID, RadioFrequencyIDentification) or direct labor's input quality。
Deposit the temperature of the high temperature load in refrigerator to be reduced to temperature value indoor between refrigerator 1, it is necessary to discharge heat, thus described computing system just seems extremely important。Heat Calculation formula in described computing system is Q=c m (t1-t2), and wherein c is the specific heat capacity of load, and m is the quality of load, and t1 is the temperature value of food, and t2 is temperature value indoor between refrigerator 1。For high temperature food, in actual mechanical process, the value mode of the specific heat capacity c of food is: for certain value after being averaged by the food often picked and placeed, replace all food being stored in refrigerator 1；The quality m of food is by detecting the detection of system Intelligent Recognition；The temperature value t1 of food can be replaced by room temperature (according to the ambient temperature value surveyed, or constant certain value as: 25 DEG C) or be possible with temperature when food is stored in refrigerator 1 by infrared temperature sensor and accurately measure；Temperature value t2 indoor between refrigerator 1 is drawn by described temperature sensor 15 detection。
The cold compensation device of the present invention includes two kinds of embodiments, it is distinctive in that between two kinds of embodiments: the temperature when temperature value t1 of the food in embodiment one is utilize infrared temperature sensor that food is stored in refrigerator 1 is accurately measured from out, accurately calculate with the heat to high temperature load, thus being accurately controlled the working time of compressor 51, cold consumption is less；And the temperature value t1 of the food in embodiment two is replaced by room temperature, it is not necessary to through accurately measuring, thus controlling roughly the working time of compressor 51。
The operation principle of described compressor 51 is prior art, no longer illustrates in this。
The cold compensation method being applied to refrigerator 1 of the present invention, mainly comprises the steps that
S1, provide a detection system, detect with the volume and/or quality to high temperature load when refrigerator 1 is stored in high temperature load；
S2, provide a computing system, carry out heat Calculation with the volume according to high temperature load and/or quality；
S3, offer one control system, predict the cold required for reducing load temperature with the result of calculation according to computing system and control the working time of refrigerator 1 refrigeration system。
As in figure 2 it is shown, when being the cold compensation device of application prior art and the present invention, the curve of cyclical fluctuations comparison diagram of temperature indoor between refrigerator 1。As can be seen from this figure, after depositing high temperature load, temperature fluctuation indoor between the refrigerator 1 of the cold compensation device of the application present invention is less than temperature fluctuation indoor between the refrigerator 1 of application prior art, the mean temperature of vaporizer 13 is again smaller than the mean temperature of the vaporizer 13 of existing general refrigerator simultaneously, thus decreasing energy consumption。
In sum, the refrigerator 1 of the present invention is by being provided with cold compensation device in an indoor, thus after putting into high temperature load, this cold compensation device can according to the volume of high temperature load and/or quality, dope the cold reduced required for high temperature load, and control the working time of refrigeration system in advance, thus the fluctuation of 1 indoor temperature of refrigerator not only can be reduced, the mean temperature of vaporizer 13 can also be reduced simultaneously, reduce energy consumption。
Above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from the spirit and scope of technical solution of the present invention。
