In use, the rear refrigeration outlet 33 is used to supply air to the rear side of the refrigeration space 20, and the side refrigeration outlet 33 is used to supply air to the side of the refrigeration space 20. The first refrigerating air path a and the second refrigerating air path B operate simultaneously, so that air can be supplied to the rear side and the side surface of the refrigerating space 20 at the same time, and the cooling speed of the refrigerating space 20 is increased.

When the temperatures of the refrigerating space 20 and the freezing space 10 both reach the temperature requirement rapidly, the circulating refrigeration mode can be operated, and under the circulating refrigeration mode, the first refrigerating air valve A1, the second refrigerating air valve B1 and the freezing air valve C1 are closed, and the circulating air valve D1 is opened.

in the quick-cooling freezing space mode, the first cold-storage air valve A1, the second cold-storage air valve B1 and the circulating air valve D1 are closed, and the freezing air valve C1 is opened.
When the refrigerator works, the cold storage space quick cooling mode is operated firstly, then the freezing space quick cooling mode is operated, the cold energy is supplied to the cold storage space 20 firstly and then is supplied to the freezing space 10 specially, the whole temperature of the refrigerator is favorably and quickly reduced, and meanwhile, the working time of the compressor can be shortened, so that the frosting amount on the evaporator is reduced. Therefore, the problem of large frosting amount of the evaporator on the existing air-cooled refrigerator can be effectively improved. In the quick cooling mode of the freezing space, the circulation duct D1 is closed to prevent the air flow from entering the refrigerating space 20 through the circulation duct D.
More preferably, the control method further includes: and a circulation cooling mode in which the first refrigerating air valve A1, the second refrigerating air valve B1 and the freezing air valve C1 are closed and the circulation air valve D1 is opened. When the temperatures of the refrigerating space 20 and the freezing space 10 both reach the temperature requirement rapidly, the circulating refrigeration mode can be operated, and under the circulating refrigeration mode, the first refrigerating air valve A1, the second refrigerating air valve B1 and the freezing air valve C1 are closed, and the circulating air valve D1 is opened. At this time, the cool air in the freezing space 10 is returned to the refrigerating space 20 through the circulation air duct D, and then returned to the freezing space 10 through the cooling device via the circuit.
Specifically, the refrigerator is started to operate, the refrigerating space quick-cooling mode is operated firstly, and the freezing space quick-cooling mode is operated after the temperature of the refrigerating space 20 meets the requirement; when the temperature of the space for freezing 10 reaches a requirement, the circulation cooling mode is finally operated. The above-mentioned switching of the operation mode can be performed by means of sensor recognition. The operation of the compressor is controlled by the refrigerating space 20, and two temperature sensors are disposed in the refrigerating space 20, respectively at the upper and lower portions of the refrigerating space 20. When the compressor is started, the cold air in the refrigerating space 20 is supplied mainly, and when the temperature in the refrigerating space 20 reaches the requirement, the temperature of the freezing space 10 is completely and independently supplied. When the temperature of the freezing space 10 reaches the requirement, whether the temperature of the refrigerating space 20 reaches the requirement is judged, if so, the operation of the compressor is stopped, otherwise, the compressor does not stop working.
As shown in fig. 7, in the technical solution of the present invention, the automatic operation in the above three modes can be realized by reasonably arranging a sensor in the refrigerator. Specifically, sensors may be provided in the freezing space 10 and the refrigerating space 20, so that the conversion of the three modes is realized through the temperature measurement program of the sensors.
Here, the sensor a is arranged in the freezing space 10 and measures the temperature of the freezing space 10; the sensors b and c are arranged in the refrigerating space 20 and distributed in a step mode, and mainly measure the temperature of the upper portion and the lower portion of the refrigerating space 20.
"the temperature difference between the sensors b and c is less than or equal to t1" is used for judging whether the temperature equalization of the refrigerating space 20 meets the requirement that the temperature equalization is lower than t1, if yes, the temperature of the sensor a of the refrigerating space 10 is judged in the next step, and if not, the refrigerating space 20 is continuously cooled in the previous step;
"the temperature of the sensor a is less than or equal to t2" is to determine whether the temperature of the freezing space 10 meets the requirement of t2, if yes, it is indicated that the temperature of the freezing space 10 at this time meets the requirement, but because the temperature of the refrigerating space 20 may rise when the refrigerator is dedicated for the cooling capacity of the freezing space 10, the temperature of the refrigerating space 20 needs to be determined at this time, the flow jumps to determine "whether the temperatures of the sensors b and c are both less than t3", where t3 is a value slightly higher than t1, so that the temperature equalization of the refrigerating space 20 is required to be less than t3, and the difference between the sensors b and c is not determined. If not, the temperature of the refrigerating space 10 does not reach the standard at the moment, and the next step is carried out to specially cool the refrigerating space 10;
3. after the last step of cooling the freezing space 10, the temperature of the freezing space 10 needs to be determined continuously, i.e., "is the temperature of the sensor a less than or equal to t2? If not, return to the previous step to continue cooling the refrigerated space 10, if so, the reason for the special purpose of the refrigerated space 10 will result in an increase in the temperature of the refrigerated space 20, as explained by the same "2", and therefore further determination of the temperature of the refrigerated space 20 will be required, if the refrigerated space 20 does not meet the requirements "sensors b and c
Is the temperature less than t3? "the refrigerating space 20 needs to be cooled again at this time,
otherwise, the next step is carried out.
"the second refrigerating air valve B1 and the freezing air valve C1 are closed, and the first refrigerating air valve A1 and the circulating air valve D1 are opened", at this time, the air passage circulation cooling is realized in the freezing space 10 and the refrigerating space 20. The circulating air path at this time is: the air passage into the refrigerating space 20 is only the opening of the circulation air passage D in fig. 5, and the air passages returning to the refrigerating space 20 are included.
"are sensors b and c both less than t6? If the temperature of the refrigerating space 20 satisfies the requirement at this time, it may be determined that the temperature of the refrigerating space 10 also satisfies the requirement. If the requirement is met, the evaporator of the refrigerator can not be used for refrigerating. The temperature t6 satisfies: t1 is more than or equal to t6 and less than or equal to t3.
Note: the circulation damper D1 is used to close the circulation duct D in fig. 5, so that the requirement of "cooling capacity dedicated to the refrigerating space 10" is satisfied, and the air volume does not enter the refrigerating space 20.
In the air duct design of the refrigerator, the refrigeration multi-air duct works mainly when the refrigerator is just started and works in a defrosting recovery period, and the refrigerator still works in a single-air duct circulating air supply mode during final normal refrigeration.
Two air ducts are arranged in the refrigerating space 20, that is, double air ducts are used for supplying air into the refrigerating space 20, so that the refrigerating space 20 can be cooled at the highest speed. Theoretically, the greater the temperature drop rate of the refrigerating space 20, the shorter the operating time of the compressor is actually, the shorter the operating time of the evaporator is, and thus the amount of frost formation of the evaporator is reduced.
In theory, the advantage of the patent setting to supply air to the refrigerating space 20 first and then to the freezing space 10 is that the negative effect of the reduction in air flow circulation efficiency due to the air path short circuit caused by the simultaneous supply of mixed air to the freezing space 10 and the refrigerating space 20 can be reduced. Therefore, the cooling efficiency of the refrigerating space 20 and the freezing space 10 can be increased.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the embodiment of the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
