2 is a schematic structural view of the split air supply device 20 in the refrigerator 100 of FIG. 1. The split air supply device 20 may generally include a housing 21 and an adjusting member (not shown in the figure due to being disposed inside the housing 21). Shown in it). The housing 21 may have at least one air inlet 221 and a plurality of air outlets 22 to allow airflow into the housing 21 via the at least one air inlet 221 and out of the housing 21 from the plurality of air outlets 22.

3 is a schematic diagram of a refrigeration control method of a refrigerator in accordance with one embodiment of the present invention. The refrigeration control method of the refrigerator can be applied to the refrigerator 100 of any of the above embodiments. As shown in FIG. 3, the food-based refrigerator temperature control method can perform the following steps:

Step S302, detecting the actual temperature of the refrigerating space 11 and the freezing space;

Step S304, setting a freezing parameter of the freezing space according to an actual temperature of the freezing space, and setting a refrigeration parameter of the refrigerating space 11 according to an actual temperature of the refrigerating space 11 when an actual temperature of the at least one freezing space is greater than a preset freezing starting temperature;

In step S306, the compressor, the fan 23, the refrigerating damper, and the split air supply device 20 are operated according to a preset state corresponding to the set according to the set of the refrigerating parameter and the freezing parameter.

In step S302, the actual temperatures of the refrigerating space 11 and the freezing space can be detected by temperature sensors provided in the refrigerating space 11 and the freezing space. The type, size and installation position of the temperature sensor can be set according to actual needs and conditions. The refrigerator 100 of the present embodiment is provided with a refrigerating space 11, a first freezing space 12, and a second freezing space 13, and temperature sensors may be respectively disposed in the three storage spaces to detect the actual temperatures of the three storage spaces.

The refrigerating parameter and the freezing parameter in step S302 and step S304 each include: a first parameter and a second parameter. The values of the first parameter and the second parameter are different. For example, the first parameter may be 0, and the second parameter may be 1. The first parameter and the second parameter may indicate whether refrigeration is required for each storage space, for example, the first parameter 0 indicates that refrigeration is not required, and the second parameter 1 indicates that refrigeration is required. The specific values of the above two parameters are merely examples, and are not intended to limit the present invention. In other embodiments, the first parameter and the second parameter may be other different values.

Since the refrigerator 100 of the present embodiment is provided with the refrigerating space 11, the first freezing space 12, and the second freezing space 13, the freezing parameter may include the first freezing parameter of the first freezing space 12 and the second freezing of the second freezing space 13 parameter. That is, the set of parameters in step S306 is a set of three values. In other embodiments, when the refrigerator 100 is provided with only one refrigerated space and one freezer space, the set of parameters may be a set of two values.

In step S304, the freezing parameter of the freezing space is set according to the actual temperature of the freezing space. Since the freezing space of the refrigerator 100 of the present embodiment may include: the first freezing space 12 and the second freezing space 13, the freezing parameter may include the first freezing parameter. And the second freezing parameter. Specifically, the step of setting the first freezing parameter of the first freezing space 12 includes: determining whether the actual temperature of the first freezing space is greater than a preset first freezing start temperature; and if so, setting the first freezing parameter to the second parameter, If not, setting the first freezing parameter to the first parameter; and setting the second freezing parameter of the second freezing space 13 comprises: determining whether the actual temperature of the second freezing space 13 is greater than a preset second freezing starting temperature; and if And setting the second freezing parameter to the second parameter, and if not, setting the second freezing parameter to the first parameter.

The actual temperature of the at least one freezing space in step S304 is greater than the preset freezing start temperature, that is, the actual temperature of the first freezing space 12 is greater than the first freezing starting temperature or the actual temperature of the second freezing space 13 is greater than the second freezing starting temperature. When the refrigeration temperature of the refrigerating space 11 is set according to the actual temperature of the refrigerating space 11, specifically, it can be determined whether the actual temperature of the refrigerating space 11 is greater than a preset refrigerating temperature; and if so, the refrigerating parameter is set to the second parameter, if not Set the refrigerating parameter to the first parameter.

When the actual temperature of the at least one freezing space is greater than the preset freezing start temperature, the refrigeration parameter of the refrigerating space 11 may be set according to the actual temperature of the refrigerating space 11, if the actual temperature in the first freezing space 12 is less than or equal to the first freezing start When the temperature and the actual temperature of the second freezing space 13 are less than or equal to the second freezing start temperature, the refrigeration parameter may be directly set as the first parameter. That is to say, when neither the first freezing space 12 nor the second freezing space 13 needs to be cooled, the direct default refrigerating space 11 does not need to be cooled, and the actual temperature condition of the refrigerating space 11 is no longer judged, and the compressor, etc. can be lowered. The frequency of opening the device effectively reduces energy consumption.

The set of different refrigeration parameters and freezing parameters in step S306, the preset states of the corresponding compressor, fan 23, refrigerating damper and split air supply device 20 are also different. Specifically, a state information table may be pre-configured, and the preset state corresponding to different parameter sets is pre-stored in the state information table, and after determining the parameter set, the corresponding preset state may be matched. The preset state includes: the rotation speed of the compressor and the fan 23; the opening and closing state of the refrigerating damper; the opening and closing state of the refrigerating air outlet 222, the first freezing air outlet 223, and the second freezing air outlet 224 of the branch air blowing device 20. .

The following describes a specific example of a status information table:

When the refrigerating parameter, the first freezing parameter and the second freezing parameter are all the first parameters, the corresponding preset state is: the compressor and the fan 23 are shut down, the refrigerating damper is closed, and the refrigerating air outlet 222 of the shunting air supply device 20 is closed. The first freezing air outlet 223 and the second freezing air outlet 224 are both closed.

When the refrigerating parameter and the first freezing parameter are the first parameter, and the second freezing parameter is the second parameter, the corresponding preset state is: the compressor operates at a preset first compressor speed, and the fan 23 is preset. When the fan speed is operated, the refrigerating damper is closed, the refrigerating air outlet 222 of the branch air supply device 20 and the first refrigerating air outlet 223 are closed, and the second refrigerating air outlet 224 is opened.

When the refrigerating parameter and the second freezing parameter are the first parameter, and the first freezing parameter is the second parameter, the corresponding preset state is: the compressor operates at the first compressor speed, and the fan 23 operates at the first fan speed, and refrigerates When the damper is closed, the refrigerating air outlet 222 and the second freezing air outlet 224 of the branch air blowing device 20 are closed, and the first freezing air outlet 223 is opened.

When the refrigerating parameter is the first parameter, the first freezing parameter and the second freezing parameter are the second parameter, the corresponding preset state is: the compressor operates at a second compressor speed greater than or equal to the first compressor speed, and the fan 23 The second fan speed is equal to or higher than the first fan speed, the refrigerating damper is closed, the refrigerating air outlet 222 of the split air supply device 20 is closed, and the first refrigerating air outlet 223 and the second refrigerating air outlet 224 are opened.

When the refrigerating parameter and the second freezing parameter are the second parameter, when the first freezing parameter is the first parameter, the corresponding preset state is: the compressor operates at a third compressor speed greater than or equal to the second compressor speed, and the fan 23 The third fan speed is greater than or equal to the second fan speed, the refrigerating damper is opened, the refrigerating air outlet 222 and the second refrigerating air outlet 224 of the shunt air supply device 20 are opened, and the first refrigerating air outlet 223 is closed.

When the refrigerating parameter and the first freezing parameter are the second parameter, and the second freezing parameter is the first parameter, the corresponding preset state is: the compressor operates at the third compressor speed, and the fan 23 operates at the third fan speed, and refrigerates When the damper is opened, the refrigerating air outlet 222 and the first freezing air outlet 223 of the branch air blowing device 20 are opened, and the second freezing air outlet 224 is closed.

When the refrigerating parameter, the first freezing parameter and the second freezing parameter are both the second parameter, the corresponding preset state is: the compressor operates at a fourth compressor speed greater than or equal to the third compressor speed, and the fan 23 is greater than or equal to The fourth fan speed of the third fan speed is operated, the refrigerating damper is opened, and the refrigerating air outlet 222, the first refrigerating air outlet 223, and the second refrigerating air outlet 224 of the branch air supply device 20 are all turned on.

It should be noted that, in step S306, the compressor, the fan 23, the refrigerating damper, and the split air supply device 20 can operate for a preset period according to a preset state corresponding to the set to meet the cooling demand of each storage space. In the process of setting the duration, the process of detecting the temperature and setting the parameters is no longer performed, and it can be determined that the actual temperature of the storage space is slightly lowered to determine that it does not require refrigeration, thereby causing the working state of the compressor and the like to frequently change. After the preset duration of work, the above steps can be re-executed for a new cooling control.

The refrigeration control method of the refrigerator of the present embodiment detects the actual temperature of the refrigerating space 11 and the freezing space; sets the freezing parameter of the freezing space according to the actual temperature of the freezing space, and the actual temperature of the at least one freezing space is greater than the preset freezing start At the time of temperature, the refrigeration parameter of the refrigerating space 11 is set according to the actual temperature of the refrigerating space 11; and the compressor, the fan 23, the refrigerating damper, and the shunting air supply device 20 are arranged according to the preset corresponding to the collection according to the refrigerating parameter and the set of the freezing parameters. The state work can realize single cooling of a single storage space or simultaneous cooling of a plurality of storage spaces, comprehensively considering the actual temperature conditions of the refrigerating space 11 and the freezing space, and determining whether the refrigerating space 11 needs to be cooled when at least one freezing space needs to be cooled. If all the freezing space does not require cooling, the default refrigerating space does not require cooling, which can reduce the opening frequency of compressors and other equipment, and effectively reduce energy consumption.

Among them, the specific values of compressor speed and fan speed can be set according to actual needs and conditions. And in most cases, the compressor speed and fan speed are proportional to the ambient temperature of the refrigerator 100, that is, the higher the ambient temperature, the greater the compressor speed and fan speed. For example, when the ambient temperature is less than 16 ° C, the first compressor speed is 1380, the second compressor speed is 1800, the third compressor speed is 2160, the fourth compressor speed is 2580; and the ambient temperature is greater than or equal to 16 ° C and When the temperature is less than 28 ° C, the first compressor speed is 1590, the second compressor speed is 1980, the third compressor speed is 2580, the fourth compressor speed is 3000; when the ambient temperature is 28 ° C or more and less than 35 ° C, The first compressor speed is 1800, the second compressor speed is 2160, the third compressor speed is 3000, the fourth compressor speed is 3420; when the ambient temperature is greater than or equal to 35 ° C and less than 43 ° C, the first compressor speed For 1980, the second compressor speed is 2580, the third compressor speed is 3420, the fourth compressor speed is 3840; when the ambient temperature is greater than or equal to 43 °C, the first compressor speed is 3000, and the second compressor speed is At 3420, the third compressor speed is 3840 and the fourth compressor speed is 4200.

The refrigeration control method of the refrigerator of the embodiment, when the actual temperature of the at least one freezing space is greater than the preset freezing start temperature, that is, the actual temperature TF1 of the first freezing space 12 is greater than the first freezing starting temperature tf1 or the second freezing space. When the actual temperature TF2 of 13 is greater than the second refrigerating start temperature tf2, the refrigerating parameter R (State) of the refrigerating space 11 can be set according to the actual temperature TR of the refrigerating space 11, and specifically, whether the actual temperature TR of the refrigerating space 11 is greater than the pre-determination can be determined. Set the refrigerating start temperature tr; and if so, set the refrigerating parameter R (State) to the second parameter 1, and if not, set the refrigerating parameter R (State) to the first parameter 0.

However, if the actual temperature TF1 of the first freezing space 12 is less than or equal to the first freezing start temperature tf1 and the actual temperature TF2 of the second freezing space 13 is less than or equal to the second freezing start temperature tf2, the refrigerating parameter R (State) may be directly set as the first Parameter 0. That is to say, when neither the first freezing space 12 nor the second freezing space 13 needs to be cooled, the direct default refrigerating space 11 does not need to be cooled, and the actual temperature condition of the refrigerating space 11 is no longer judged, and the compressor, etc. can be lowered.

It should be noted that, in step S428, the compressor, the fan 23, the refrigerating damper, and the split air supply device 20 can operate for a preset period according to a preset state corresponding to the set to meet the cooling demand of each storage space. In the process of setting the duration, the process of detecting the temperature and setting the parameters is no longer performed, and it can be determined that the actual temperature of the storage space is slightly lowered to determine that it does not require refrigeration, thereby causing the working state of the compressor and the like to frequently change. After the preset duration of work, the above steps can be re-executed for a new cooling control.

The refrigeration control method of the refrigerator of the embodiment can realize single cooling of a single storage space or simultaneous cooling of a plurality of storage spaces, comprehensively considering the actual temperature conditions of the refrigerating space 11 and the freezing space, and judging when at least one freezing space needs cooling. Whether the refrigerated space needs to be refrigerated, if all the freezing space does not need to be cooled, the default refrigerating space 11 does not need to be cooled, which can reduce the opening frequency of compressors and other equipment, and effectively reduce energy consumption.
