Below with reference to accompanying drawing, describe in detail according to the control method of the air door of the refrigerator of the embodiment of the present invention.
As shown in Figure 1-2, the control method according to the air door of the refrigerator of the embodiment of the present invention, comprises the following steps:
A: judge between the refrigeration of described refrigerator, whether chamber needs refrigeration.
B: when need to freeze in chamber between described refrigeration, start described air door and open from complete closed position and detect the first temperature T 1 indoor between described refrigeration simultaneously.Make and open air door this when action, indoor temperature between refrigeration.
C: detect the second temperature T 2 indoor between described refrigeration after very first time section M1, and described the first temperature T 1 is compared with described the second temperature T 2.For example, open this action of air door and time rise after 10 minutes making, detect temperature indoor between described refrigeration, and by this temperature the temperature comparison when starting to freeze to obtain a temperature difference.
D: when T1-T2 < X1, make described air door reset to complete closed position and return to steps A, wherein X1 is the first preset temperature, and for example, the first preset temperature X1 can be 1 degree Celsius.
That is to say, between the refrigeration of refrigerator, the signal that needs refrigeration is sent in chamber, and air door is opened from the position of closing completely.Detect respectively air door when making opening action to making the temperature on 10 minutes these two points opening action, obtain a temperature difference.By this temperature difference and the first preset temperature, be for example 1 degree Celsius, compare.If the temperature difference is less than 1 degree Celsius, illustrate that air door does not have to be transformed into fully open position from complete closed position because being subject to external interference.Now, air door reset to the position of closing completely and repeat above step.Until the temperature difference detecting is more than or equal to 1 degree Celsius, illustrate that air door is transformed into fully open position from complete closed position.
Thus, when between the refrigeration of refrigerator, need to freeze in chamber, can, by comparing to make air door to get rid of interference the temperature difference and the first preset temperature, so that air door is transformed into fully open position from complete closed position as early as possible after adjusting, thereby can improves refrigerating efficiency and save energy consumption.
According to one embodiment of present invention, as shown in Figure 2, the control method of the air door of described refrigerator also comprises:
E: judge between the refrigeration of described refrigerator, whether chamber needs to stop refrigeration.
F: when chamber need to stop freezing between described refrigeration, start described air door and close from fully open position and detect the 3rd temperature T 3 indoor between described refrigeration simultaneously.Make and close air door this when action, indoor temperature between refrigeration.
G: detect the 4th temperature T 4 indoor between described refrigeration after the second time period M2, and described the 4th temperature T 4 is compared with described the 3rd temperature T 3.For example, close this action of air door and time rise after 10 minutes making, detect temperature indoor between described refrigeration, and by this temperature the temperature comparison when starting to freeze to obtain another temperature difference.
H: when T4 < T3 or T4-T3 < X2, make described air door reset to fully open position and return to step e, wherein X2 is the second preset temperature, and for example, the second preset temperature X2 can be 1 degree Celsius.
In other words, between the refrigeration of refrigerator, the signal that need to stop refrigeration being sent in chamber, and air door is closed from the position of opening completely.Detect respectively air door when making closing motion to making the temperature on 10 minutes these two points closing motion, obtain a temperature difference.By this temperature difference and the second preset temperature, be for example 1 degree Celsius, compare.If the temperature difference be less than 1 degree Celsius or make closing motion after the temperature of 10 minutes be less than the temperature while making closing motion, illustrate that air door does not have to be transformed into from fully open position complete closed position because being subject to external interference, cold wind continues to blow to chamber between the refrigeration of refrigerator.Now, air door reset to fully open position and repeat above step.Until the temperature difference detecting be more than or equal to 1 degree Celsius or make closing motion after the temperature of 10 minutes be more than or equal to the temperature while making closing motion, illustrate that air door has been transformed into complete closed position from fully open position.
Thus, when between the refrigeration of refrigerator, chamber need to stop freezing, can be by by the temperature difference and the second preset temperature compares or temperature that the second time period M2 initial sum is stopped on two points compares, air door is got rid of to be disturbed, so that air door is transformed into as early as possible complete closed position after adjusting from fully open position, thereby can further save energy consumption.
Further, according to some embodiments of the present invention, judge between the refrigeration of described refrigerator that whether chamber needs refrigeration is by temperature indoor between described refrigeration and the first temperature threshold are compared and carried out, and judge between the refrigeration of described refrigerator that whether chamber needs to stop refrigeration is by temperature interior between described cool room and the second temperature threshold are compared and carried out.That is to say, when temperature indoor between the refrigeration of refrigerator is during higher than the first temperature threshold, refrigerator sends the signal that needs refrigeration; When temperature indoor between the refrigeration of refrigerator is during lower than the second temperature threshold, refrigerator sends the signal that stops refrigeration.Thus, can make the temperature in indoor between the refrigeration of refrigerator keep relative stability, to improve the reliability of refrigerator.
