Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings describe the air quantity control method of the refrigerator of the embodiment of the present invention, device and there is the refrigerator of this air quantity controller.
Fig. 1 is the flow chart of the air quantity control method of refrigerator according to an embodiment of the invention.It should be noted that, in an embodiment of the present invention, refrigerator can be wind cooling refrigerator.
As shown in Figure 1, the air quantity control method of this refrigerator can comprise:
S101, obtains the available machine time of compressor and the opening time of air door.
Particularly, after refrigerator is in refrigerating state, can obtain compressor in refrigerator available machine time (namely from start startup optimization to the current time) and air door from being opened to current opening time.
S102, according to the available machine time of compressor and the opening time of air door, the dampers angular to air door controls.
Wherein, in an embodiment of the present invention, dampers angular can be understood is air door open angle.
Specifically, in an embodiment of the present invention, the time difference between the available machine time of compressor and the opening time of air door can first be obtained.Afterwards, can control according to the dampers angular of this time difference to air door.More specifically, first can deduct the opening time of air door with the available machine time of compressor, obtain the time difference between both, can judge the time difference and according to judged result, different control be carried out to the dampers angular of air door afterwards.
In an embodiment of the present invention, according to the specific implementation that the dampers angular of time difference to air door controls be: if the time difference is less than very first time threshold value, then keep the dampers angular of air door constant; If the time difference is more than or equal to very first time threshold value and be less than the second time threshold, then the dampers angular of air door is closed 15%; If the time difference is more than or equal to the second time threshold and be less than the 3rd time threshold, then the dampers angular of air door is closed 30%; And if the time difference is more than or equal to the 3rd time threshold and is less than the 4th time threshold, then the dampers angular of air door is closed 45%.Wherein, in an embodiment of the present invention, very first time threshold value can be 0.1H, and the second time threshold can be 0.3H, and the 3rd time threshold can be 0.5H, and the 4th time threshold can be 0.7H, and wherein, H is the available machine time of compressor.
Such as, time difference between the available machine time and the opening time of air door of compressor is less than very first time threshold values, when being less than available machine time value (i.e. the 0.1H) of the compressor of 0.1 times as the time difference, can run according to current state, namely keep the dampers angular of air door constant, maintain current dampers angular and carry out work; When the time difference is more than or equal to very first time threshold values and is less than the second time threshold values, the dampers angular of air door can be closed 15% on the basis of upper once dampers angular; When the time difference is more than or equal to the second time threshold values and is less than the 3rd time threshold values, dampers angular can be closed 15% again on the basis of upper once dampers angular; When the time difference is more than or equal to the 3rd time threshold values and is less than the 4th time threshold values, dampers angular can be closed 15% more again on the basis of upper once dampers angular.In an embodiment of the present invention, if the time difference is more than or equal to the 4th time threshold values, then the dampers angular of air door can be maintained 10 degree.Thus, according to the corresponding open angle adjusting air door of time extent between available machine time of compressor and the opening time of air door, as difference is larger, open angle is less, thus ensure that energy consumption of refrigerator is minimum.
Further, in order to ensure that refrigerator can fast cooling, in one embodiment of the invention, this air quantity control method also can comprise: obtain accumulated running time after the defrost of refrigerator; If accumulated running time is less than or equal to pre-set threshold value after defrost, then dampers angular is opened to maximum.Wherein, in an embodiment of the present invention, pre-set threshold value can be 2h.Thus, Temperature drop in refrigerator speed can be ensured.
Particularly, after refrigerator is in refrigerating state, first can obtain accumulated running time after the defrost of refrigerator, can judge accumulated running time after this defrost afterwards, if accumulated running time is less than or equal to 2h hour after defrost, then the air door of controlled ice making case is opened completely, to ensure Temperature drop in refrigerator speed.
Be to be understood that, in an embodiment of the present invention, if accumulated running time is greater than 2h hour after defrost, then can think that now the temperature of refrigerator has been reduced to certain threshold values, now can start to control according to the dampers angular of time difference to air door between available machine time of compressor and the opening time of air door, to make refrigerator load drop to floor level, ensure that energy consumption is minimum.
According to the air quantity control method of the refrigerator of the embodiment of the present invention, the available machine time of compressor and the opening time of air door can be obtained, and according to the available machine time of compressor and the opening time of air door, the dampers angular to air door controls, namely according between the size of room load, as the time extent between available machine time of compressor and the opening time of air door, judge the open angle of air door, as difference is larger, open angle is less, refrigerator load is dropped to minimum, and reduce the energy consumption of refrigerator.
In order to make those skilled in the art to more clearly understand the present invention, can illustrate below.
For example, as shown in Figure 2, after refrigerator is in refrigerating state, can first judge accumulated running time after defrost, as whether accumulated running time after judging defrost is greater than pre-set threshold value (as 2h) (S201).When judging that after defrost, accumulated running time is less than or equal to reservation threshold, work (S202) opened completely by the air door in controlled ice making case; When judging that after defrost, accumulated running time is greater than pre-set threshold value, first can obtain the available machine time H of compressor and the opening time Y of air door, time difference X between the available machine time H of compressor and the opening time Y of air door can be calculated according to H and Y afterwards, and this time difference X is judged (S203).First time difference X and very first time threshold values (as 0.1H) can be compared, namely judge whether time difference X is less than 0.1H (S204), if so, then continue to run (S205) according to current state; If not, then judge whether time difference X is more than or equal to very first time threshold values and is less than second time threshold values (as 0.3H) (S206) further, if so, then dampers angular is closed 15% (S207) on the basis of upper once dampers angular; If not, judging whether time difference X is more than or equal to the second time threshold values and is less than the 3rd time threshold values (as 0.5H) (S208) if then closed 15% (S209) on the basis of upper once dampers angular by dampers angular again further; If not, then judge whether time difference X is more than or equal to the 3rd time threshold values and is less than the 4th time threshold values (as 0.7H) (S210) further, if so, then dampers angular is closed 15% (S211) more again on the basis of upper once dampers angular; If not, then air door is maintained open angle 10 degree to run (S212).Thus, can find out, the difference between the available machine time of compressor and the opening time of air door is larger, and the open angle of air door is less, refrigerator load is dropped to minimum, and reduces the energy consumption of refrigerator.

In an embodiment of the present invention, the specific implementation that airdoor control module 20 controls according to the dampers angular of time difference to air door is: if the time difference is less than very first time threshold value, then keep the dampers angular of air door constant; If the time difference is more than or equal to very first time threshold value and be less than the second time threshold, then the dampers angular of air door is closed 15%; If the time difference is more than or equal to the second time threshold and be less than the 3rd time threshold, then the dampers angular of air door is closed 30%; And if the time difference is more than or equal to the 3rd time threshold and is less than the 4th time threshold, then the dampers angular of air door is closed 45%.Wherein, in an embodiment of the present invention, very first time threshold value can be 0.1H, and the second time threshold can be 0.3H, and the 3rd time threshold can be 0.5H, and the 4th time threshold can be 0.7H, and wherein, H is the available machine time of compressor.
Further, in order to ensure that refrigerator can fast cooling, in one embodiment of the invention, airdoor control module 20 also can be used for obtaining accumulated running time after the defrost of refrigerator, and when after defrost, accumulated running time is less than or equal to pre-set threshold value, dampers angular is opened to maximum.Wherein, in an embodiment of the present invention, pre-set threshold value can be 2h.More specifically, after refrigerator is in refrigerating state, airdoor control module 20 first can obtain accumulated running time after the defrost of refrigerator, can judge accumulated running time after this defrost afterwards, if accumulated running time is less than or equal to 2h hour after defrost, then the air door of controlled ice making case is opened completely, to ensure Temperature drop in refrigerator speed.
Be to be understood that, in an embodiment of the present invention, if accumulated running time is greater than 2h hour after defrost, then can think that now the temperature of refrigerator has been reduced to certain threshold values, now airdoor control module 20 can start to control according to the dampers angular of time difference to air door between available machine time of compressor and the opening time of air door, to make refrigerator load drop to floor level, ensure that energy consumption is minimum.
