The refrigeration temperature is used to control the refrigeration system of the refrigerator to stop running; in response to the refrigeration system stopping time being longer than the first stop time, the refrigeration system is controlled to start running to reduce the temperature of the freezer compartment of the refrigerator.

In order to solve the above technical problems, another technical solution adopted by this application is to provide a single temperature controlled air-cooled refrigerator. The air-cooled refrigerator includes a refrigerator compartment, a freezer compartment, a refrigeration system, a first temperature sensor, and a second temperature sensor. and drive control system; the refrigeration system provides refrigeration for the refrigerator and freezer compartments; first The temperature sensor is used to detect the current temperature of the refrigerator compartment; the second temperature sensor is used to detect the current ambient temperature outside the refrigerator; the drive control system is connected to the refrigeration system, the first temperature sensor, and the second temperature sensor, and the drive control system is used to execute to achieve the above control method.

Through the above method, when the refrigerating compartment stops or reduces the refrigeration request of the refrigerator because the current refrigerating compartment temperature is lower than the preset refrigeration temperature, it is judged whether the refrigeration system stops running for longer than the first stop duration, thereby predicting the freezer compartment of the refrigerator. Whether the current freezer temperature is within the required freezing temperature range of the freezer. And in response to the time when the refrigeration system stops running longer than the first stop time, that is, when the current freezing chamber temperature of the freezing chamber does not meet the freezing requirements or is about to rise to the maximum allowable temperature of the freezing chamber, the refrigeration system is controlled to start running, thereby reducing the temperature of the freezing chamber. temperature to ensure the effectiveness of the freezer compartment of the refrigerator; further, there is no need to install a temperature sensor in the freezer compartment of the refrigerator, which reduces the complexity and cost of refrigerator technology.

This application provides a method for controlling the temperature of a refrigerator and a single-temperature-controlled air-cooled refrigerator. The control method can control the temperature of a refrigerator according to the length of time the refrigeration system stops operating and the first stop when the current temperature of the refrigerator compartment is less than the preset refrigeration temperature. time, predict the current freezer temperature of the refrigerator freezer, and then control the opening and closing of the refrigeration system according to the predicted current freezer temperature to reduce the temperature of the freezer, thereby ensuring the effectiveness of the freezer; further, the refrigerator freezer The current freezer temperature does not require a temperature sensor to detect, reducing the complexity of the refrigerator design and reducing the cost of the refrigerator.

Referring to Figure 1, Figure 1 is a schematic structural diagram of an embodiment of a single temperature controlled air-cooled refrigerator provided by the present application. As shown in FIG. 1 , the single temperature controlled air-cooled refrigerator 10 includes a refrigerator compartment 110 , a freezer compartment 120 , a refrigeration system 130 , a first temperature sensor 140 , a second temperature sensor 150 and a drive control system 160 integrated on a circuit board. Among them, the refrigeration system 130 mainly includes a fan 131, a compressor 132, an evaporator (not labeled in the figure) and a condenser (not labeled in the figure). When the refrigeration system 130 is working, the compressor 132 works on the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas; the refrigerant gas enters the condenser along the pipeline, and the condenser converts the high-temperature and high-pressure refrigerant gas into liquid. Refrigerant; the refrigerant enters the electronic expansion valve to regulate and discharge the refrigerant to the evaporator; the refrigerant evaporates in the evaporator and absorbs a large amount of heat, rapidly reducing the temperature around the evaporator. When the air-cooled refrigerator 10 controls the compressor 132 and the fan 131 to run at the same time, it can reduce the temperature of the refrigerator compartment 110 and the freezer compartment 120 of the air-cooled refrigerator 10; when the air-cooled refrigerator 10 controls the compressor 132 to work, and the fan 131 stops working, it can only The temperature of the freezer compartment 120 is lowered.

The first temperature sensor 140 may be used to detect the current refrigerating compartment temperature of the refrigerating compartment 110 . The second temperature sensor 150 is used to detect the current ambient temperature outside the air-cooled refrigerator 10 . The drive control system 160 is connected to the refrigeration system 130, the first temperature sensor 140 and the second temperature sensor 150, and is used to perform a control method for realizing the temperature of the refrigerator.

The single-temperature-controlled air-cooled refrigerator 10 provided by this application can ensure the effectiveness of the freezer compartment 120 of the air-cooled refrigerator 10 when the current refrigeration temperature of the refrigerator refrigeration compartment 110 is lower than the preset refrigeration temperature.

Refer to FIG. 2 , which is a schematic flowchart of an embodiment of a refrigerator temperature control method provided by the present application. The execution subject of the refrigerator temperature control method provided by the present application may be the single-temperature-controlled air-cooled refrigerator 10 in the above embodiment. As shown in Figure 2, the refrigerator temperature control method includes the following steps:

Step S100: Obtain the current refrigerator compartment temperature of the refrigerator compartment.

The current refrigerating room temperature of the refrigerator refrigerating room 110 is obtained, and whether the refrigerating room 110 needs to request cooling is determined based on the current refrigerating room temperature, and the temperature of the refrigerating room 110 is lowered. Among them, the refrigerator compartment 110 is provided with a temperature sensor or a temperature measurement module that can measure the temperature of the refrigerator compartment 110. The refrigerator can monitor the current refrigerator compartment temperature of the refrigerator compartment 110 by obtaining the current refrigerator compartment temperature of the refrigerator compartment 110 in real time. The refrigerator controls the operation of the refrigeration system 130 of the refrigerator based on the current refrigeration temperature of the refrigeration compartment 110 and the required refrigeration temperature of the refrigeration compartment 110, thereby ensuring that the temperature of the refrigeration compartment 110 is within the refrigeration temperature range to ensure the refrigeration effect of the refrigeration compartment 110. The refrigeration temperature required by the refrigeration compartment 110 can be adjusted according to the current ambient temperature outside the refrigerator or the required temperature of the refrigerated items.

Step S110: In response to the current refrigerator compartment temperature being less than the preset refrigeration temperature, control the refrigeration system of the refrigerator to stop operating.

The current refrigeration temperature of the refrigerator 110 is obtained and compared with the preset refrigeration temperature. When the current refrigeration temperature of the refrigerator 110 is less than the preset refrigeration temperature, the refrigeration system 130 of the refrigerator is controlled to stop operating. The preset refrigeration temperature can be understood as the refrigeration temperature required by the refrigeration room 110 , or the maximum refrigeration temperature allowed by the refrigeration room 110 within the refrigeration temperature range required by the refrigeration room 110 , for example, the refrigeration temperature required by the refrigeration room 110 The range is 4℃-7℃, the preset cooling temperature can be 4℃, and the preset cooling temperature can also be 7℃.

Step S120: In response to the stop time of the refrigeration system being longer than the first stop time, control the refrigeration system to start operating to reduce the temperature of the freezer compartment of the refrigerator.

In some cases, the current ambient temperature outside the refrigerator is close to the current refrigerating compartment temperature of the refrigerating compartment 110, or the current ambient temperature outside the refrigerator is lower than the current refrigerating compartment temperature of the refrigerating compartment 110, then the current refrigerating compartment temperature may be lower than the current refrigerating compartment temperature for a long time. The preset refrigeration temperature means that the refrigeration compartment 110 does not need to be refrigerated by the refrigeration system 130 of the refrigerator or the refrigeration compartment 110 does not need to frequently request refrigeration from the refrigeration system 130 of the refrigerator to maintain the refrigeration temperature of the refrigeration compartment 110 . At this time, the refrigeration system 130 will continue to be shut down. However, the freezing temperature required by the freezing chamber 120 is much lower than the refrigeration temperature required by the refrigerating chamber 110, and when the refrigerating chamber 110 does not request cooling, the temperature in the freezing chamber 120 becomes too high as the refrigeration system 130 stops working for a long time. lead to The freezing chamber 120 loses its freezing effect.

In the embodiment of the present application, the refrigerator controls the refrigeration system 130 to stop operating when the current refrigerating compartment temperature of the refrigerating compartment 110 is lower than the preset refrigeration temperature. In order to ensure the effectiveness of the freezing compartment 120, the refrigerator obtains the duration of the refrigeration system 130 stopping operation, The current freezing temperature of the freezing chamber 120 is predicted, and when the refrigeration system 130 stops operating for longer than the first stopping time, that is, when the predicted current freezing temperature of the freezing chamber 120 cannot meet the freezing requirements, the refrigeration system 130 is controlled. Start the operation to lower the temperature of the freezing chamber 120 and ensure that the temperature of the freezing chamber 120 is lower than or equal to the freezing temperature, thereby ensuring the effectiveness of the freezing chamber 120.

Optionally, the first stop duration is associated with the current ambient temperature of the refrigerator, and corresponds to the duration of the freezer temperature being too high due to the refrigeration system 130 stopping operating at the current ambient temperature outside the refrigerator. Optionally, the lower the current ambient temperature outside the refrigerator, the longer the first stop duration.

The refrigerator temperature control method provided by this application obtains the current refrigerator temperature of the refrigerator chamber 110, and controls the refrigeration system 130 to stop operating in response to the current refrigerator temperature being less than the preset refrigeration temperature, and responds to the length of time the refrigeration system 130 stops operating. When the time period is longer than the first stop time, the refrigeration system 130 is controlled to start operating to lower the temperature of the freezer compartment 120 of the refrigerator. Through the above method, when the refrigerating compartment 110 stops or reduces the refrigeration request of the refrigerator because the current refrigerating compartment temperature is lower than the preset refrigeration temperature, it is determined whether the refrigeration system 130 stops operating for longer than the first stop duration, thereby predicting the refrigerator's Whether the current freezing temperature of the freezing chamber 120 is within the required freezing temperature range of the freezing chamber 120 . In response to the stop time of the refrigeration system 130 being longer than the first stop time, the refrigeration system 130 is controlled to start operation, that is, when the current freezing temperature of the freezing chamber 120 does not meet the freezing requirements or is about to rise to the maximum temperature allowed by the freezing chamber 120, the refrigeration system is controlled. The system 130 is started to operate, thereby reducing the temperature of the freezer compartment 120 and ensuring the effectiveness of the refrigerator freezer 120; further, there is no need to install a temperature sensor in the freezer compartment 120 of the refrigerator, which reduces the complexity and cost of the refrigerator technology.

Optionally, the refrigeration system 130 of the refrigerator includes a compressor 132 and a fan 131. When the compressor 132 of the refrigeration system 130 is controlled to start running, the refrigeration system 130 can provide refrigeration. Among them, when the compressor 132 and the fan 131 are controlled to start running at the same time, the refrigerator compartment 110 and the freezing compartment 120 can be cooled down; when the compressor 132 is controlled to start running, the fan 131 is controlled to stop running, and only the freezing compartment 120 is cooled. The refrigerator-based refrigeration system 130 includes a compressor 132 and a fan 131. In step S110, in response to the current refrigerator temperature of the refrigerator chamber 110 being less than the preset refrigeration temperature, the refrigerator-based refrigeration system 130 is controlled to stop operating, including:

Step S111: In response to the current refrigerator temperature being less than the preset refrigeration temperature, control the fan and compression The machine stops running.

In response to the current refrigerator temperature of the refrigerator compartment 110 being less than the preset refrigeration temperature, the refrigerator controls the compressor 132 and the fan 131 in the refrigeration system 130 to stop operating, that is, the compressor 132 and the fan 131 stop cooling the refrigerator compartment 110 and the freezer compartment 120 .

In step S120, in response to the stop time of the compressor 132 in the refrigeration system 130 being greater than the first stop time under the current ambient temperature, the refrigeration system 130 is controlled to start operation, including:

Step S121: In response to the compressor stopping time being longer than the first stopping time, control the compressor to start running.

The refrigerator determines whether the stop time of compressor 132 is greater than the first stop time, and the first stop time corresponds to the time period when the freezer temperature is too high due to the stop of compressor 132. Therefore, the refrigerator can determine whether compressor 132 stops. Whether the running duration is greater than the first stopping duration, thereby predicting whether the current temperature of the refrigerator freezer 120 is within the required freezing temperature range of the freezer 120 . Then, in response to the stop time of the compressor 132 being longer than the first stop time, the compressor 132 is controlled to start to reduce the temperature of the freezing chamber 120, thereby ensuring the effectiveness of the freezing chamber 120.

Optionally, after executing step S121, refer to FIG. 3, which is a schematic flowchart of another embodiment of a refrigerator temperature control method according to the present application. As shown in Figure 3, the refrigerator temperature control method can also include the following steps:

Step S130: Obtain the first operating duration of the compressor after it is started.

When the compressor 132 stops running for longer than the first stopping time, the refrigerator controls the compressor 132 to start running. After the compressor 132 has been running for a period of time, the refrigerator obtains the duration of continuous operation of the compressor 132 during this period, that is, the refrigerator obtains the first operation duration of the compressor 132 after it is turned on.

Step S140: In response to the first operating duration being greater than the first operating duration, control the compressor to stop operating.

In response to the first operating time of the compressor 132 being greater than the first operating time, the refrigerator controls the compressor 132 to stop operating. That is, the refrigerator compares the first operating time of the compressor 132 with the first operating time, and then predicts the relationship between the compressor 132 and the first operating time of the compressor 132 . After the freezing chamber 120 cools down, the current temperature of the freezing chamber 120 is determined. When the current freezing chamber temperature of the freezing chamber 120 is within the required freezing temperature range of the freezing chamber 120, the refrigerator controls the compressor 132 to stop running. Wherein, the first working time is associated with the current ambient temperature outside the refrigerator, that is, the first working time under the current ambient temperature corresponds to the current freezing temperature of the freezing compartment 120 that meets the requirement of freezing due to the compressor 132 starting to run under the current ambient temperature. Required duration. For example, when the current ambient temperature outside the refrigerator is 5°C, the first working time is 1 hour; when the current ambient temperature outside the refrigerator is 10°C, the first working time is 1 hour. One working hour is 2 hours, etc. The refrigerator adjusts the first working time based on the current ambient temperature outside the refrigerator.

The method of controlling the temperature of the refrigerator in this embodiment obtains the first operating duration of continuous operation of the compressor 132 after it is turned on, and controls the compressor 132 to stop operating in response to the first operating duration being greater than the first operating duration. Through the above method, after the compressor 132 has been continuously operated for a period of time, the refrigerator responds to the first operating time being greater than the first working time, that is, based on the first operating time and the first working time of the compressor 132, the refrigerator determines the current freezing level of the freezing chamber 120. When the room temperature meets the freezing requirements, the compressor 132 is controlled to stop working, and the power consumption of the refrigerator is reduced while ensuring the normal operation of the freezing chamber 120 to improve the energy efficiency of the refrigerator.

Optionally, in response to the stop time of the compressor 132 being longer than the first stop time, the compressor 132 is controlled to start running and the fan 131 is controlled to continue to stop running. In response to the compressor 132 stopping for longer than the first stopping time, the refrigerator controls the compressor 132 to start running, and while cooling the freezer compartment 120, the fan 131 is controlled to keep running. That is, the refrigeration system 130 of the refrigerator only lowers the temperature of the freezer compartment 120 and does not lower the temperature of the refrigerating compartment 110, so that the temperature of the refrigerating compartment 110 is not affected by the startup of the compressor 132, thereby maintaining a stable refrigeration temperature, thereby ensuring refrigerated items. not be damaged.

The refrigerator temperature control method in this embodiment controls the operation of the compressor 132 when the current refrigerator temperature of the refrigerator compartment 110 is less than the preset refrigeration temperature, and when the predicted current freezer temperature of the freezer compartment 120 does not meet the freezing requirements. At the same time, the fan 131 is kept stopped, thereby ensuring that the current refrigerator temperature of the refrigerator chamber 110 is maintained within the refrigeration temperature range, thereby ensuring that the refrigerated items are not damaged; further, the power consumption of the refrigerator can be reduced.

Optionally, the first stop duration and the first working duration of the compressor 132 are set based on the current ambient temperature outside the refrigerator. Among them, the refrigerator can calculate the first stop time and the first working time of the compressor 132 in real time based on the current ambient temperature using empirical formulas and other methods; or the refrigerator can set the first stop time corresponding to the environment based on the current ambient temperature and based on experience values. The gradient range of duration and first working duration, select the corresponding first stopping duration and first working duration according to the current environment.

Optionally, after controlling the fan 131 and the compressor 132 to stop running, the control method further includes the following steps:

Step S240: Obtain the duration of the fan stopping operation.

When the current refrigerating compartment temperature of the refrigerating compartment 110 is lower than the preset refrigeration temperature, the refrigerator controls the compressor 132 and the fan 131 to stop running. When the current ambient temperature outside the refrigerator is close to or lower than the refrigeration temperature required by the refrigeration room 110, the temperature in the refrigeration room 110 can be maintained within the refrigeration temperature range required by the refrigeration room 110 for a long time. The frequency of the refrigeration room 110 requesting cooling decreases, the fan 131 may remain out of service for a while. When the fan 131 remains stopped for a long time, the cooling capacity of the refrigerator compartment 110 is unevenly distributed. In order to improve the refrigeration quality of the refrigerator compartment 110, the refrigerator obtains the duration of the fan 131 shutdown.

Step S250: In response to the fan stopping time being longer than the second stopping time, control the fan to start running.

In response to the stop time of the fan 131 being longer than the second stop time, the refrigerator controls the fan 131 to start running to evenly distribute the cooling capacity of the refrigerator compartment 110 .

The refrigerator temperature control method of this embodiment obtains the stop time of the fan 131 and controls the fan 131 to start running in response to the stop time of the fan 131 being greater than the second stop time. Through the above method, when the stop time of the fan 131 is longer than the second stop time, the fan 131 is controlled to start running, thereby uniformly distributing the cooling capacity of the refrigerating room 110 and improving the refrigeration quality of the refrigerating room 110 .

Optionally, after the step of controlling the fan 131 to start running, the method for controlling the temperature of the refrigerator also includes:

Step S260: Obtain the second working time of the fan that continues to work after it is turned on.

After the refrigerator controls the fan 131 to start running, in order to avoid the impact of the long-term operation of the fan 131 on the refrigerated items, the refrigerator obtains the second working time of the continuous operation of the fan 131 after the fan 131 is started.

Step S270: In response to the second operating time being greater than the second operating time, control the fan to stop running.

In response to the second operating time of the fan 131 being longer than the second operating time, the fan 131 is controlled to stop operating.

In the refrigerator temperature control method of this embodiment, after the step of controlling the fan 131 to start running, the second running time period of the fan 131 that continues to work after the fan 131 is started is obtained. In response to the second running time being greater than the second working time, the fan 131 is controlled to stop running. Through the above method, when the second operating time of the refrigerator control fan 131 is longer than the second operating time, the control fan 131 stops operating to prevent the refrigerated items from being affected by the cold wind and reduce the refrigeration quality of the refrigerator compartment 110; further, the performance of the refrigerator is reduced. Consumption.

Optionally, the second stop duration and the second working duration of the fan 131 are set based on the current ambient temperature outside the refrigerator. Among them, the refrigerator can calculate the second stop time and the second working time of the fan 131 in real time based on the current ambient temperature outside the refrigerator using empirical formulas and other methods; or the refrigerator can set the second stop time and the second working time corresponding to the environment based on the current ambient temperature and based on experience values. The gradient range of the stop duration and the second working duration is selected according to the current environment.

Optionally, before performing the step of obtaining the current refrigerating chamber temperature of the refrigerating chamber 110 of the refrigerator, the method for controlling the temperature of the refrigerator may further include the following steps:

Step S160: Obtain the current ambient temperature outside the refrigerator and the preset cooling temperature corresponding to the current ambient temperature.

The refrigerator can also obtain the current ambient temperature of the refrigerator and the preset cooling temperature corresponding to the current ambient temperature. The refrigerator can adjust the preset cooling temperature according to the current ambient temperature, or the refrigerator is set with different preset cooling temperature gradients based on the current ambient temperature. When the current ambient temperature of the refrigerator changes, the preset cooling temperature also changes with the current ambient temperature. Adjustment.

The method of controlling the temperature of the refrigerator in this embodiment obtains the current ambient temperature outside the refrigerator, obtains the corresponding preset refrigeration temperature based on the current ambient temperature, and adjusts the preset refrigeration temperature at any time to maintain the refrigeration temperature of the refrigerator compartment 110 It adapts to changes in the ambient temperature outside the refrigerator, thereby achieving precise control of the refrigeration temperature of the refrigerator compartment 110 by the refrigerator.

Optionally, the refrigerator is provided with a heating element in the refrigerator compartment 110, and the method for controlling the temperature of the refrigerator further includes the following steps:

Step S370: In response to the current ambient temperature being less than the preset ambient temperature, control the operation of the heating element to increase the temperature of the refrigerator compartment.

When the current ambient temperature outside the refrigerator is lower than or close to the required refrigeration temperature of the refrigeration compartment 110, the temperature in the refrigeration compartment 110 of the refrigerator can be maintained within the refrigeration temperature range for a long time, so that the refrigeration compartment 110 does not require cooling. Since the temperature of the freezing chamber 120 is much lower than the refrigeration temperature, in order to ensure the effectiveness of the freezing chamber 120, when the current ambient temperature is lower than the preset ambient temperature, the refrigerator controls the heating element to work to increase the temperature of the refrigeration chamber 110, thereby improving refrigeration. The frequency with which the chamber 110 requests cooling, thereby lowering the temperature of the freezing chamber 120, ensures the effectiveness of the freezing chamber 120.

The method for controlling the temperature of the refrigerator in this embodiment is to set a heating element in the refrigerator compartment 110, and when the current ambient temperature outside the refrigerator is lower than the preset ambient temperature, the heating element is controlled to increase the temperature of the refrigerator compartment 110, thereby increasing the temperature of the refrigerator compartment 110. The frequency with which the refrigerator compartment 110 requests cooling is increased, thereby lowering the temperature of the freezing compartment 120 and ensuring the effectiveness of the freezing compartment 120.

Optionally, the refrigerator temperature control method also includes the following steps:

Step S170: In response to the current refrigerator compartment temperature being greater than or equal to the preset refrigeration temperature, control the compressor and the fan to start running.

In response to the current refrigerator temperature of the refrigerator compartment 110 being greater than or equal to the preset refrigeration temperature, the refrigerator controls the fan 131 and the compressor 132 to start operating to reduce the temperatures of the refrigerator compartment 110 and the freezer compartment 120 to ensure normal operation of the refrigerator.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of another embodiment of a method for controlling the temperature of a refrigerator according to the present application. As shown in Figure 4, after the refrigerator is powered on, when the refrigeration temperature range is 4-7°C, it can be considered that 7°C is the preset cooling temperature and 4°C is the stop cooling temperature. Obtain the current ambient temperature outside the refrigerator and the current temperature of the refrigerator compartment 110 Refrigerator temperature, in response to the current refrigerator temperature being lower than the preset refrigeration temperature corresponding to the current ambient temperature, the compressor 132 and the fan 131 are controlled to stop running; after the compressor 132 and the fan 131 are controlled to stop running, the information that the compressor 132 stops running is obtained. duration, and in response to the stop time of compressor 132 being greater than the first stop time, the compressor 132 is controlled to start running while keeping the fan 131 in a stopped state; after the refrigerator controls the operation of compressor 132, it obtains the first running time of compressor 132 , and in response to the first operating time being greater than the first operating time, the compressor 132 is controlled to stop operating, the fan 131 is controlled to maintain the stopped operating state, and finally returns to the step of obtaining the current ambient temperature and the current temperature of the refrigerator compartment 110 . Also in response to the current refrigerating room temperature being greater than or equal to the preset refrigeration temperature, the compressor 132 and the fan 131 are controlled to start running, and the current refrigerating room temperature of the refrigerating room 110 is obtained in real time. When the current refrigerating room temperature is less than the preset refrigeration temperature , the compressor 132 and the fan 131 are controlled to stop running.
