[0002] At present, in order to improve space utilization and increase the beauty of the overall layout of the room, built-in refrigerators have developed rapidly and have become the mainstream of the market and are popular among users. Built-in refrigerators place the external condenser in the compressor compartment. The compressor and condenser are in a relatively closed environment, with poor heat dissipation conditions, which affects the refrigeration of the refrigerator and even causes safety hazards.

[0003] Currently, a cooling fan is installed in the compressor compartment to dissipate heat from the compressor. When a thermal control abnormality occurs in the compressor compartment, the compressor is first shut down and then the abnormality is reported to notify the staff for maintenance. However, while waiting for maintenance, the compressor is in a shutdown state and the user's cooling needs cannot be guaranteed.

[0004] With regard to the problem in the prior art that when a heat control anomaly occurs in the compressor compartment of a refrigerator, the compressor is in a running state while waiting for maintenance, and the user's cooling needs cannot be met, no effective solution has been proposed so far.

[0016] If the cooling rate is less than the second threshold, the compartment with the highest priority among the refrigerating compartment, the freezing compartment and the variable temperature compartment is determined, the compartment with the highest priority is controlled to operate intermittently according to the set temperature, and the remaining compartments are controlled to stop operating.

[0017] Further, determining the compartment with the highest priority among the refrigerating compartment, the freezing compartment, and the variable temperature compartment includes:

[0018] Obtaining the accumulated door opening time of the refrigerated compartment, the frozen compartment, and the variable temperature compartment;

[0019] The compartment with the shortest cumulative door opening time among the refrigerating compartment, the freezing compartment and the temperature-changing compartment is determined as the compartment with the highest priority.

[0020] Furthermore, the preset conditions include:

[0021] The temperature of the compressor compartment is greater than a preset temperature, or the heating rate of the compressor compartment is greater than a preset rate.

[0022] Furthermore, after the temperature of the compressor compartment meets a preset condition, the method further includes:

[0023] Determining whether the speed of the heat dissipation fan reaches the maximum speed;

[0024] If yes, a high temperature alarm is triggered;

[0025] If not, the speed of the cooling fan is controlled to increase, and then it is determined whether the preset condition is still met; if it is met, the speed of the cooling fan is controlled to continue to increase until it reaches the maximum speed and still meets the preset condition, triggering a high temperature alarm; if it is not met, the cooling fan is controlled to maintain the current speed.

If the cooling rate of the compressor compartment is fast, it indicates that the temperature rise in the compressor compartment is within a controllable range, and priority can be given to satisfying the user's refrigeration needs; if the cooling rate of the compressor compartment is slow, priority should be given to operational reliability, sacrificing part of the refrigeration demand to avoid the temperature in the compressor compartment from getting out of control.

[0047] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] Example 1

[0049] Built-in refrigerators place the external condenser in the compressor compartment. The compressor and condenser are in a relatively closed environment with poor heat dissipation conditions, which affects the refrigeration of the refrigerator and may even cause safety hazards.

[0050] Currently, a cooling fan is installed in the compressor compartment to dissipate heat from the compressor. When a thermal control abnormality occurs in the compressor compartment, the compressor is first shut down and then the abnormality is reported to notify the staff for maintenance. However, while waiting for maintenance, the compressor is in a shutdown state and the user's cooling needs cannot be guaranteed.

[0051] In view of the problem in the prior art that after a heat control anomaly occurs in a compressor compartment of a refrigerator, the compressor is in a running state while waiting for maintenance, and the user's refrigeration needs cannot be met, this embodiment provides a heat control method applied to an embedded refrigerator, the embedded refrigerator comprising a refrigerating compartment, a freezing compartment, a variable temperature compartment, and a compressor, the compressor being arranged in the compressor compartment, and a heat dissipation fan being further arranged in the compressor compartment. Figure 1 is a flow chart of a thermal control method according to an embodiment of the present invention. Figure 1 As shown, the thermal control method includes:

[0052] S101, obtaining the temperature of the compressor compartment of the built-in refrigerator.

[0053] In a specific implementation, a temperature sensor is arranged in the compressor compartment to detect the temperature of the compressor compartment, and then transmits the temperature to the control end.

[0054] S102, after the temperature of the compressor compartment meets the preset conditions, a high temperature alarm is triggered.

[0055] The above preset conditions are used to determine whether the compressor compartment is in a state of thermal control failure. If it is determined that the compressor compartment is in a state of thermal control failure, a high temperature alarm is triggered, and maintenance personnel can remotely receive the high temperature alarm information of the compressor compartment at the monitoring port.

[0056] S103, after the high temperature alarm is triggered, the operating states of the refrigeration compartment, the freezing compartment, and the variable temperature compartment are controlled according to the cooling rate of the compressor compartment, thereby adjusting the heat load in the compressor compartment.

[0057] After the high temperature alarm is triggered, the cooling fan in the compressor compartment is turned on to dissipate heat for the compressor and condenser in the compressor compartment.

[0058] The cooling rate of the compressor compartment can reflect whether the thermal control of the compressor compartment has failed and the severity of the thermal control failure. The compressor compartment includes a condenser and a compressor. If the refrigeration compartment, the freezer compartment, and the variable temperature compartment are not operated, the user's refrigeration needs will not be met. However, the more compartments are in operation, the higher the operating load of the condenser and the compressor, and the more heat is generated, which will increase the heat load in the compressor compartment. Therefore, it is necessary to control the operating status of the refrigeration compartment, the freezer compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment, and then adjust the heat load in the compressor compartment, so as to meet the user's refrigeration needs to a certain extent and avoid excessive temperature in the compressor compartment.

[0059] It should be noted that the steps of controlling the operating status of the refrigerated compartment, the frozen compartment and the variable temperature compartment according to the cooling rate of the compressor compartment, and then adjusting the heat load in the compressor compartment, can be written into the controller of the refrigerator, automatically triggered after the high temperature alarm is triggered, or triggered by maintenance personnel through corresponding operations in the port interface.

[0060] The thermal control method of this embodiment controls the cooling fan in the compressor compartment to remain on after the compressor compartment is in a state of thermal control failure and triggers a high temperature alarm, and then controls the operating states of the refrigerated compartment, the frozen compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment, thereby adjusting the heat load in the compressor compartment. If the cooling rate of the compressor compartment is fast, it indicates that the temperature rise in the compressor compartment is within a controllable range, and priority can be given to satisfying the user's cooling needs; if the cooling rate of the compressor compartment is slow, priority should be given to operational reliability, sacrificing part of the cooling demand to avoid the temperature in the compressor compartment from getting out of control. The thermal control method of this embodiment balances cooling demand and reliability, and can meet the user's cooling demand to a certain extent while avoiding excessive temperatures in the compressor compartment, which could cause safety hazards.

[0061] After the heat dissipation fan is turned on, it will not work immediately. It is necessary to collect temperature data over a period of time to truly reflect the temperature changes in the compressor compartment, and then accurately control the operating states of the refrigerated compartment, the freezer compartment, and the variable temperature compartment. Therefore, the operating states of the refrigerated compartment, the freezer compartment, and the variable temperature compartment are controlled according to the cooling rate of the compressor compartment, including: after controlling the heat dissipation fan to be turned on for a preset time, calculating the cooling rate of the compressor compartment within the preset time; controlling the operating states of the refrigerated compartment, the freezer compartment, and the variable temperature compartment according to the interval in which the above cooling rate is located.

[0062] In order to accurately adjust the heat load in the compressor compartment based on the temperature change, the operating states of the refrigerated compartment, the freezer compartment and the variable temperature compartment are controlled according to the interval in which the cooling rate is located, including: if the cooling rate is greater than the first threshold, the refrigerated compartment, the freezer compartment and the variable temperature compartment are controlled to operate normally according to the set temperature; if the cooling rate is less than or equal to the first threshold, and greater than or equal to the second threshold, the compartment with the highest priority among the refrigerated compartment, the freezer compartment and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate continuously according to the set temperature, and the remaining compartments are controlled to stop operating; if the cooling rate is less than the second threshold, the compartment with the highest priority among the refrigerated compartment, the freezer compartment and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate intermittently according to the set temperature, and the remaining compartments are controlled to stop operating.

[0063] If the cooling rate is greater than the first threshold, it indicates that the cooling effect of the cooling fan is good, the temperature rise in the compressor compartment is within the controllable range, the thermal control is not invalid, and the refrigeration demand can be given priority. Therefore, the refrigerated compartment, the frozen compartment, and the variable temperature compartment are all controlled to operate normally according to the set temperature; if the cooling rate is less than or equal to the first threshold, and greater than or equal to the second threshold, it indicates that the cooling effect of the cooling fan is not good, and the thermal control is slightly invalid. Therefore, it is necessary to consider the problem of operational reliability and sacrifice part of the refrigeration demand. However, in order to avoid the deterioration of stored food, the compartment with the highest priority among the refrigerated compartment, the frozen compartment, and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate continuously according to the set temperature, and the remaining compartments are controlled to stop operating; if the cooling rate is less than the second threshold, it indicates that the cooling effect of the cooling fan is very poor, the thermal control is seriously invalid, and the continuous operation needs of the compartment with the highest priority cannot be fully met. After determining the compartment with the highest priority among the refrigerated compartment, the frozen compartment, and the variable temperature compartment, the compartment with the highest priority is controlled to operate intermittently according to the set temperature, and the remaining compartments are controlled to stop operating.

[0064] If the door of a compartment is often opened, it means that the food stored in the compartment needs to be taken out frequently, which means that the food stored in the compartment is stored for a short time. The temperature of such food rises briefly and will not cause deterioration. Therefore, the priority of this compartment is lower; if the door of a compartment is rarely opened or is opened briefly, it means that the stored things do not need to be taken out frequently, which means that the food stored in the compartment needs to be stored for a long time by the user. Generally, the temperature rise of such food will cause deterioration. Therefore, the priority of this compartment is higher, and its refrigeration operation should be guaranteed first. In summary, determining the compartment with the highest priority among the refrigerated compartment, the frozen compartment and the variable temperature compartment includes: obtaining the cumulative door opening time of the refrigerated compartment, the frozen compartment and the variable temperature compartment, which can reflect the number of door openings and the time of each door opening; determining the compartment with the shortest cumulative door opening time among the refrigerated compartment, the frozen compartment and the variable temperature compartment as the compartment with the highest priority.

[0065] As mentioned above, the above-mentioned preset conditions are used to determine whether the compressor compartment is in a state of thermal control failure. In the state of thermal control failure, the temperature of the compressor compartment will be higher and the temperature rise rate will be faster. Therefore, the above-mentioned preset conditions include: the temperature of the compressor compartment is greater than the preset temperature, or the heating rate of the compressor compartment is greater than the preset rate.

[0066] After the thermal control fails, if the speed of the cooling fan has not reached the maximum, the speed of the cooling fan can be continued to be increased to control the temperature rise. Therefore, in order to exhaust all means to control the temperature rise of the compressor compartment, after the temperature of the compressor compartment meets the preset conditions, the above method also includes: judging whether the speed of the cooling fan has reached the maximum speed, if so, triggering a high temperature alarm, if not, controlling the speed of the cooling fan to increase, and then judging whether the above preset conditions are still met; if satisfied, controlling the speed of the cooling fan to continue to increase until it reaches the maximum speed and still meets the preset conditions, triggering a high temperature alarm; if not, controlling the cooling fan to maintain the current speed.

[0067] Example 2

[0068] This embodiment provides another heat control method. Figure 2 Flow chart of a high temperature warning process according to an embodiment of the present invention. Figure 2 As shown in the figure, the high temperature warning process includes:

[0069] S21, controls the cooling fan of the compressor compartment to turn on, and then detects the temperature of the compressor compartment through a sensor.

[0070] S22, determine whether the temperature of the compressor compartment is greater than a preset temperature, if yes, execute step S23, if not, repeat step S22.

[0071] S23, determining whether the rotation speed of the cooling fan reaches the maximum rotation speed; if yes, executing step S24; if no, executing step S25.

[0072] S24, triggers high temperature alarm.

[0073] S25, controlling the speed of the cooling fan to increase, and then returning to step S22.

[0074] In this embodiment, the temperature data and high temperature alarm information detected by the sensor are sent to the port of the maintenance personnel through the data sending module. The maintenance personnel receive the high temperature alarm information remotely and then process it.

[0075] The refrigerator has a fan for heat dissipation placed in the compressor compartment, and a temperature sensor near the condenser in the compressor compartment. The real-time temperature of the compressor compartment is collected through the temperature sensor, and the fan is turned on to dissipate heat from the compressor compartment. When the temperature of the compressor compartment exceeds the preset temperature, the fan speed is increased. However, if the temperature of the compressor compartment still exceeds the preset temperature after increasing the fan speed for multiple times and remains at a high temperature, the thermal control is determined to be invalid. The voice system of the refrigerator alarms to remind the user to contact the after-sales personnel in time. At the same time, the refrigerator automatically starts the steps of controlling the operating status of the refrigerated compartment, the frozen compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment, thereby adjusting the heat load in the compressor compartment. Alternatively, after receiving the information, the after-sales personnel remotely start the program of controlling the operating status of the refrigerated compartment, the frozen compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment through the operation interface of the port, thereby adjusting the heat load in the compressor compartment.

[0076] Figure 3 is a flow chart of a thermal control process according to an embodiment of the invention, as shown in Figure 3 As shown, the thermal control process includes:

[0077] S31, controlling the cooling fan to continuously run for a preset time period.

[0078] The above preset duration can be set to 1 minute.

[0079] S32, calculating the cooling rate of the compressor compartment.

[0080] The fan is controlled to run for 1 minute. The temperature T2 of the compressor compartment after the preset running time is collected and subtracted from the temperature T1 of the compressor compartment when the cooling fan starts running, and the temperature drop rate V = (T1-T2) / t1 is calculated.

[0081] S33, determine the interval of the cooling rate of the compressor compartment; if V>first threshold value V1, execute step S34; if the second threshold value V2≤V≤first threshold value V1, execute step S35; if V<second threshold value V2, execute step S36.

[0082] S34, controls the refrigeration compartment, the freezing compartment and the variable temperature compartment to operate normally according to the set temperature.

[0083] S35, the compartment with the highest priority continues to operate at the set temperature, and the remaining compartments are controlled to stop operating.

[0084] S36, control the compartment with the highest priority to operate intermittently according to the set temperature, and control the other compartments to stop operating.

[0085] Among them, determining the room with the highest priority among the refrigerated room, the frozen room and the variable temperature room includes: obtaining the cumulative door opening time of the refrigerated room, the frozen room and the variable temperature room, the cumulative door opening time can reflect the number of door openings and the time of each door opening; determining the room with the shortest cumulative door opening time among the refrigerated room, the frozen room and the variable temperature room as the room with the highest priority.

[0086] If the cooling rate is greater than the first threshold, it indicates that the cooling effect of the cooling fan is good, the temperature rise in the compressor compartment is within the controllable range, the thermal control is not invalid, and the refrigeration demand can be given priority. Therefore, the refrigerated compartment, the frozen compartment, and the variable temperature compartment are all controlled to operate normally according to the set temperature; if the cooling rate is less than or equal to the first threshold, and greater than or equal to the second threshold, it indicates that the cooling effect of the cooling fan is not good, and the thermal control is slightly invalid. Therefore, it is necessary to consider the problem of operational reliability and sacrifice part of the refrigeration demand. However, in order to avoid the deterioration of stored food, the compartment with the highest priority among the refrigerated compartment, the frozen compartment, and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate continuously according to the set temperature, and the remaining compartments are controlled to stop operating; if the cooling rate is less than the second threshold, it indicates that the cooling effect of the cooling fan is very poor, the thermal control is seriously invalid, and the continuous operation needs of the compartment with the highest priority cannot be fully met. After determining the compartment with the highest priority among the refrigerated compartment, the frozen compartment, and the variable temperature compartment, the compartment with the highest priority is controlled to operate intermittently according to the set temperature, and the remaining compartments are controlled to stop operating.

[0087] Example 3

[0088] This embodiment provides a heat control device, which is applied to a built-in refrigerator. The built-in refrigerator includes a compressor, a condenser, a refrigerating compartment, a freezing compartment, and a variable temperature compartment. The compressor and the condenser are arranged in a compressor compartment. A heat dissipation fan is also arranged in the compressor compartment. Figure 4 : is a structural block diagram of a thermal control device according to an embodiment of the present invention. Figure 4 As shown, the thermal control device includes: a temperature acquisition module 10, which is used to obtain the temperature of the compressor compartment of the built-in refrigerator. In the specific implementation, a temperature sensor is set in the compressor compartment to detect the temperature of the compressor compartment, and then transmit it to the control end. An alarm module 20 is used to trigger a high temperature alarm after the temperature of the compressor compartment meets a preset condition. The above preset condition is used to determine whether the compressor compartment is in a state of thermal control failure. If the compressor compartment is determined to be in a state of thermal control failure, a high temperature alarm is triggered, and maintenance personnel can remotely receive the high temperature alarm information of the compressor compartment at the monitoring port. A control module 30 is used to control the operating status of the refrigeration compartment, the freezing compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment after the high temperature alarm is triggered, thereby adjusting the heat load in the compressor compartment.

[0089] After the high temperature alarm is triggered, the cooling fan in the compressor compartment is controlled to be turned on to achieve the purpose of cooling the compressor and condenser in the compressor compartment.

[0090] The cooling rate of the compressor compartment can reflect whether the thermal control of the compressor compartment has failed and the severity of the thermal control failure. The compressor compartment includes a condenser and a compressor. If the refrigeration compartment, the freezer compartment, and the variable temperature compartment are not operated, the user's refrigeration needs will not be met. However, the more compartments are in operation, the higher the operating load of the condenser and the compressor, and the more heat is generated, which will increase the heat load in the compressor compartment. Therefore, it is necessary to control the operating status of the refrigeration compartment, the freezer compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment, and then adjust the heat load in the compressor compartment, so as to meet the user's refrigeration needs to a certain extent and avoid excessive temperature in the compressor compartment.

[0091] It should be noted that the steps of controlling the operating status of the refrigerated compartment, the frozen compartment and the variable temperature compartment according to the cooling rate of the compressor compartment, and then adjusting the heat load in the compressor compartment, can be written into the controller of the refrigerator, automatically triggered after the high temperature alarm is triggered, or triggered by maintenance personnel through corresponding operations in the port interface.

[0092] The thermal control device of this embodiment controls the cooling fan in the compressor compartment to turn on after the compressor compartment is in a state of thermal control failure and triggers a high temperature alarm, and then controls the operating states of the refrigeration compartment, the freezing compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment, thereby adjusting the heat load in the compressor compartment. If the cooling rate of the compressor compartment is fast, it indicates that the temperature rise in the compressor compartment is within a controllable range, and priority can be given to satisfying the user's cooling needs; if the cooling rate of the compressor compartment is slow, priority should be given to operational reliability, sacrificing part of the cooling demand to avoid the temperature in the compressor compartment from getting out of control. The above scheme balances cooling demand and reliability, and can meet the user's cooling demand to a certain extent while avoiding excessive temperatures in the compressor compartment, which could cause safety hazards.

[0093] After the cooling fan is turned on, it will not work immediately. It is necessary to collect temperature data over a period of time to truly reflect the temperature changes in the compressor compartment, and then accurately control the operating status of the refrigerated compartment, the freezer compartment, and the variable temperature compartment. Therefore, when the control module 30 controls the operating status of the refrigerated compartment, the freezer compartment, and the variable temperature compartment according to the cooling rate of the compressor compartment, the specific operations performed include: after controlling the cooling fan to be turned on for a preset time, calculating the cooling rate of the compressor compartment within the preset time; controlling the operating status of the refrigerated compartment, the freezer compartment, and the variable temperature compartment according to the interval in which the above cooling rate is located.

[0094] In order to accurately adjust the heat load in the compressor compartment based on the temperature change, the control module 30 controls the operating status of the refrigerated compartment, the freezer compartment and the variable temperature compartment according to the interval in which the cooling rate is located, and specifically performs the following operations: when the cooling rate is greater than the first threshold, the refrigerated compartment, the freezer compartment and the variable temperature compartment are controlled to operate normally according to the set temperature; when the cooling rate is less than or equal to the first threshold, and greater than or equal to the second threshold, the compartment with the highest priority among the refrigerated compartment, the freezer compartment and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate continuously according to the set temperature, and the remaining compartments are controlled to stop operating; when the cooling rate is less than the second threshold, the compartment with the highest priority among the refrigerated compartment, the freezer compartment and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate intermittently according to the set temperature, and the remaining compartments are controlled to stop operating.

[0095] If the cooling rate is greater than the first threshold, it indicates that the cooling effect of the cooling fan is good, the temperature rise in the compressor compartment is within the controllable range, the thermal control is not invalid, and the refrigeration demand can be given priority. Therefore, the refrigerated compartment, the frozen compartment, and the variable temperature compartment are all controlled to operate normally according to the set temperature; if the cooling rate is less than or equal to the first threshold, and greater than or equal to the second threshold, it indicates that the cooling effect of the cooling fan is not good, and the thermal control is slightly invalid. Therefore, it is necessary to consider the problem of operational reliability and sacrifice part of the refrigeration demand. However, in order to avoid the deterioration of stored food, the compartment with the highest priority among the refrigerated compartment, the frozen compartment, and the variable temperature compartment is determined, and the compartment with the highest priority is controlled to operate continuously according to the set temperature, and the remaining compartments are controlled to stop operating; if the cooling rate is less than the second threshold, it indicates that the cooling effect of the cooling fan is very poor, the thermal control is seriously invalid, and the continuous operation needs of the compartment with the highest priority cannot be fully met. After determining the compartment with the highest priority among the refrigerated compartment, the frozen compartment, and the variable temperature compartment, the compartment with the highest priority is controlled to operate intermittently according to the set temperature, and the remaining compartments are controlled to stop operating.

[0096] If the door in a compartment is often opened, it means that the food stored in the compartment needs to be taken out frequently, which further means that the food stored in the compartment is stored for a short time. The temperature of such food rises briefly and will not cause deterioration. Therefore, the priority of this compartment is lower; if the door in a compartment is rarely opened or is opened briefly, it means that the stored things do not need to be taken out frequently, which means that the food stored in the compartment needs to be stored for a long time by the user. Generally, the temperature rise of such food will cause deterioration. Therefore, the priority of this compartment is higher, and its refrigeration operation should be guaranteed first. In summary, when determining the compartment with the highest priority among the refrigerating compartment, the freezing compartment and the variable temperature compartment, the control module 30 specifically performs the following operations: obtaining the cumulative door opening time of the refrigerating compartment, the freezing compartment and the variable temperature compartment, which can reflect the number of door openings and the time of each door opening; determining the compartment with the shortest cumulative door opening time among the refrigerating compartment, the freezing compartment and the variable temperature compartment as the compartment with the highest priority.

[0097] As mentioned above, the above-mentioned preset conditions are used to determine whether the compressor compartment is in a state of thermal control failure. In the state of thermal control failure, the temperature of the compressor compartment will be higher and the temperature rise rate will be faster. Therefore, the above-mentioned preset conditions include: the temperature of the compressor compartment is greater than the preset temperature, or the heating rate of the compressor compartment is greater than the preset rate.

[0098] After the thermal control fails, if the speed of the cooling fan has not reached the maximum, the speed of the cooling fan can be continued to be increased to control the temperature rise. Therefore, in order to exhaust all means to control the temperature rise of the compressor compartment, after the temperature of the compressor compartment meets the preset conditions, the alarm module 20 is also used to: determine whether the speed of the cooling fan has reached the maximum speed, if so, trigger a high temperature alarm, if not, control the speed of the cooling fan to increase, and then determine whether the above-mentioned preset conditions are still met; if satisfied, control the speed of the cooling fan to continue to increase until it reaches the maximum speed and still meets the preset conditions, and then trigger a high temperature alarm; if not, control the cooling fan to maintain the current speed.
