[0002] During refrigerator use, overcrowding can clog the temperature sensor, preventing airflow from reaching it. This food blockage alters the sensor's sensitivity. When food obstructs the sensor, it becomes less sensitive, leading to a greater difference between the average internal temperature and the sensor's readings. This causes the internal temperature to deviate significantly from the set range, resulting in abnormal temperature control in the refrigerator. Summary of the Invention

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0018] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0019] This application provides a method for controlling the compartment temperature of a refrigerator device. Furthermore, the refrigerator device in this application includes a top temperature sensor located on the top of the refrigerator device and compartment temperature sensors located in the compartments of the refrigerator device, with the number of compartment temperature sensors being greater than or equal to 2.
[0020] In a specific example, the number of compartment temperature sensors in this application embodiment can be determined according to the number of compartments in the refrigerator. For example, if the refrigerator has three compartments, one temperature sensor can be set in each compartment, and the number of compartment temperature sensors is 3; if the refrigerator has four compartments, one temperature sensor can be set in each compartment, and the number of compartment temperature sensors is 4.
[0021] like Figure 1 As shown, the steps of the method in this application embodiment include:
[0022] Step 101: Detect the first temperature sensor in the compartment temperature sensor, wherein the first temperature sensor is the sensor used in the compartment temperature sensor when the refrigerator is running normally.
[0023] It should be noted that in this embodiment of the application, only one temperature sensor is needed to control the temperature of the compartment when the refrigerator is running normally. Therefore, even if multiple temperature sensors are installed in the refrigerator, usually only one temperature sensor is running to detect the temperature of the refrigerator.
[0024] Step 102: If the first temperature sensor in the compartment temperature sensor is detected to be abnormal, the second temperature sensor in the compartment temperature sensor is activated sequentially, and after each second temperature sensor is activated, it is checked whether the activated second temperature sensor is abnormal.
[0025] It should be noted that the first temperature sensor malfunction in this embodiment refers to a change in the sensitivity of the temperature sensor to receive temperature, making it unable to obtain the correct temperature value inside the refrigerator in a timely manner.
[0026] Step 103: If a normal second temperature sensor is detected, the room temperature is controlled based on the normal second temperature sensor.
[0027] Through steps 101 to 103 above, multiple temperature sensors are set in the refrigerator. If the currently operating temperature sensor malfunctions (such as being blocked by food in the refrigerator), it is necessary to activate other compartment temperature sensors in the refrigerator to ensure that the detection of the refrigerator compartment temperature is timely and accurate, and to avoid the refrigerator compartment temperature deviating significantly from the original set temperature range.
[0028] In an optional embodiment of this application, the method of detecting the first temperature sensor in the compartment temperature sensor involved in step 101 above may further include:
[0029] Step 11: Obtain the first temperature difference and the second temperature difference, wherein the first temperature difference is the difference between the temperature detected by the top temperature sensor and the temperature detected by the first temperature sensor when the refrigerator is running normally, and the second temperature difference is the difference between the temperature detected by the top temperature sensor and the temperature detected by the first temperature sensor when the refrigerator is empty.
[0030] Step 12: If the absolute value of the difference between the first temperature difference and the second temperature difference is greater than the first preset threshold, determine that the first temperature sensor is abnormal.
[0031] Step 13: If the absolute value of the difference between the first temperature difference and the second temperature difference is less than or equal to the first preset threshold, the first temperature sensor is determined to be normal.
[0032] For steps 11 to 13 above, in a specific example, the temperature difference ΔT1 (first temperature difference) between the top temperature sensor and temperature sensor P1 (first temperature sensor) after the refrigerator is running normally, and the temperature difference ΔT0 (second temperature difference) when the refrigerator is empty, are obtained. Based on this, ΔTP1 = ΔT1 - ΔT0 is the difference between the temperature sensor P1 and the top temperature sensor Pt when the refrigerator is empty and when it is running normally. ΔT0 is the temperature data when the refrigerator is empty, and its value is fixed and will not change depending on the food placement. ΔT1, however, changes depending on the placement. The change is greater when temperature sensor P1 is blocked, that is, ΔTP1 increases when blocked. Further, it is determined whether ΔTP1 is greater than the preset threshold T1. If it is, it indicates that temperature sensor P1 is malfunctioning (such as being blocked by food in the refrigerator). In the specific example, the preset threshold T can be 2.5℃, that is, the first preset threshold can be 2.5℃.
[0033] In a specific example, taking a compartment temperature sensor that includes two second temperature sensors, the method described in step 102 above, which involves sequentially controlling the activation of the second temperature sensors in the compartment temperature sensor and detecting whether any abnormalities have occurred in the activated second temperature sensors after each activation, can further include:
[0034] Step 21: Control the first second temperature sensor to start and detect the first second temperature sensor;
[0035] Step 22: When the first temperature sensor malfunctions, the second temperature sensor in the control room temperature sensor is activated and tested.
[0036] In a specific example, if the current compartment temperature sensor includes two second temperature sensors, it means the refrigerator divides the compartment into three parts. When no food obstructs the temperature sensor, the temperature sensor located in the middle (first temperature sensor) typically operates. This is because the temperature varies at different locations within the refrigerator compartment, making the middle sensor relatively accurate for temperature detection. Therefore, the first temperature sensor can be the middle one, and the first and second second temperature sensors can be the temperature sensors for the top and bottom compartments, respectively. The detection order is as follows: first, the first temperature sensor in the middle compartment is detected; then, the temperature sensor (second temperature sensor) in the top compartment is detected; and finally, the temperature sensor (second temperature sensor) in the bottom compartment is detected.
[0037] Based on steps 11 to 13 above, if ΔTP1 corresponding to the first temperature sensor is greater than Tpreset1, then it is further determined whether ΔTP2 corresponding to the second temperature sensor in the upper compartment is greater than Tpreset2. If ΔTP2 is greater than Tpreset2, then it is further determined whether ΔTP3 corresponding to the third temperature sensor in the lower compartment is greater than Tpreset3. It should be noted that since the temperature sensors are at different heights within the refrigerator, i.e., the temperature differences at their locations also differ, the values of Tpreset1, Tpreset2, and Tpreset3 are also different. If the sensors are distributed from top to bottom as the second temperature sensor, the first temperature sensor, and the third temperature sensor, their corresponding preset thresholds should also increase, for example, Tpreset2 is 2℃, Tpreset1 is 2.5℃, and Tpreset3 is 3℃, respectively.
[0038] In an optional embodiment of this application, the method of controlling the room temperature based on a second temperature sensor that has not shown any abnormalities, involved in step 103 above, may further include:
[0039] Step 31: Determine the temperature value of the second temperature sensor at the time corresponding to the power-on point of the first temperature sensor as the power-on point temperature value of the second temperature sensor.
[0040] Step 32: Determine the temperature value of the second temperature sensor at the time corresponding to the stop point of the first temperature sensor as the temperature value of the stop point of the second temperature sensor.
[0041] Step 33: Based on the temperature values at the start and stop points of the second temperature sensor, the second temperature sensor is operated to control the room temperature.
[0042] As can be seen from steps 31 to 33 above, after the first temperature sensor malfunctions, the second temperature sensor needs to be activated. However, the start-up and stop-down temperatures of the second temperature sensor need to be determined based on the first temperature sensor. That is, when all temperature sensors are functioning correctly, the temperature received by the second temperature sensor at the start-up time of the first temperature sensor is determined as the start-up temperature value of the second temperature sensor, and the temperature received by the second temperature sensor at the stop-down time of the first temperature sensor is determined as the stop-down temperature value of the second temperature sensor. It should be noted that because the first and second temperature sensors are located in different positions within the refrigerator, their start-up and stop-down temperatures are different.
[0043] In optional embodiments of this application, such as Figure 2 As shown, the method in this application embodiment may further include:
[0044] Step 201: If the absence of a normal second temperature sensor is detected, obtain the target temperature difference value corresponding to each temperature sensor in the compartment temperature sensor. The target temperature difference value is the absolute value of the difference between the first target temperature difference and the second target temperature difference. The first target temperature difference is the difference between the temperature detected by the top temperature sensor and the temperature detected by each temperature sensor when the refrigerator is running normally. The second target temperature difference is the difference between the temperature detected by the top temperature sensor and the temperature detected by each temperature sensor when the refrigerator is empty.
[0045] Step 202: Select the smallest target temperature difference from multiple target temperature differences, and determine the target temperature sensor in the compartment temperature sensor corresponding to the smallest target temperature difference;
[0046] Step 203: Correct the power-on and power-off points of the target temperature sensor, and run the target temperature sensor based on the modified power-on and power-off points.
[0047] As can be seen from steps 201 to 203 above, if all temperature sensors currently installed in the refrigerator, except for the top temperature sensor, malfunction, and if the malfunction is caused by food obstruction, then it is necessary to select the temperature sensor with the least obstruction from the obstructed temperature sensors, correct its start-up and stop-down points, and then operate the temperature sensor based on the corrected start-up and stop-down points to avoid the refrigerator compartment temperature deviating significantly from the original set temperature range.
[0048] Furthermore, the method for correcting the power-on and power-off points of the target temperature sensor involved in step 203 above may further include:
[0049] Step 41: When the refrigerator is running empty, obtain the first start-up point and the second stop point of the temperature sensor;
[0050] Step 42: When the target temperature sensor is abnormal, obtain the first temperature value of the target temperature sensor at the time corresponding to the power-on point of the top temperature sensor, and obtain the second temperature value of the target temperature sensor at the time corresponding to the power-off point of the top temperature sensor.
[0051] Step 43: Determine the average of the temperature value at the first power-on point and the first temperature value as the power-on point after correction by the target temperature sensor;
[0052] Step 44: The average of the temperature value at the second stop point and the second temperature value is determined as the stop point after correction by the target temperature sensor.
[0053] As can be seen from steps 41 to 44 above, when all the first and second temperature sensors are abnormally blocked, if the difference between the first temperature sensor and the top sensor is the smallest between empty and normal operation, then the start-stop point of the first sensor needs to be corrected for temperature control. Because the top sensor is located on the air outlet track, it will cool down rapidly when the air is ventilated, and heat up rapidly when the air is stopped because it is on the top of the cabinet. Therefore, it is prone to frequent start-stop and short single start-up time. So, the top sensor is not suitable as the temperature control point. When the first temperature sensor is least blocked, it receives temperature slowly due to poor airflow. When the empty cabinet is running, the stop point t11 of the first temperature sensor corresponds to the stop point of the top sensor. The top sensor reaches the stop point, but due to the blockage of the first temperature sensor, the temperature received is slow and has not yet reached t11. The temperature of the first temperature sensor at this time is recorded as t11', and the corrected t11 = (t11 + t11') / 2 is set as the new stop point of the first temperature sensor. When the empty box is running, the power-on point t12 of the first temperature sensor corresponds to the power-on point of the top sensor. The top sensor reaches the power-on point, but the temperature reception is slow due to the blockage of the first temperature sensor and has not yet reached t12. The temperature of the first temperature sensor at this time is recorded as t12', and the corrected t12 = (t12 + t12') / 2 is set as the new power-on point of the first temperature sensor.

The first target temperature difference is the difference between the temperature detected by the top temperature sensor and the temperature detected by each temperature sensor when the refrigerator is running normally. The second target temperature difference is the difference between the temperature detected by the top temperature sensor and the temperature detected by each temperature sensor when the refrigerator is empty. The second processing module is used to select the smallest target temperature difference from multiple target temperature differences and determine the target temperature sensor in the compartment temperature sensor corresponding to the smallest target temperature difference. The third processing module is used to correct the power-on and power-off points of the target temperature sensor and run the target temperature sensor based on the modified power-on and power-off points.
