Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a method, device, electronic device, and storage medium for adjusting the temperature of a refrigerator compartment. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common appliance used to preserve food or other items at low temperatures and is widely used in daily life and industry. In the process of food preservation, the temperature stability of the refrigerator compartment is very important. Large temperature fluctuations will have an adverse effect on the preservation of food. The temperature inside each refrigeration compartment of existing refrigerators is generally affected by external environmental factors. If the fluctuation range of the compartment temperature change is too large, it will affect the refrigeration effect of refrigerated food. If the temperature inside the refrigeration compartment is not adjusted accordingly in time, it is easy for the refrigeration compartment temperature to be too low in low ambient temperatures, causing food to freeze, or the refrigeration compartment temperature to be too high in high ambient temperatures, causing food to spoil.

[0047] In this embodiment, a method for adjusting the temperature of a refrigerator compartment is provided. Figure 2 FIG. 1 is a flow chart of the refrigerator compartment temperature adjustment method of this embodiment. Figure 2 As shown, the process includes the following steps:

[0048] Step S201: During the refrigeration stop period, the temperature of each position of the refrigerator compartment is detected in real time by a plurality of preset temperature sensors.

[0049] Specifically, existing refrigerators offer three cooling methods: air cooling, direct cooling, and air-direct cooling. Air cooling involves blowing the cooling energy from the evaporator into the refrigerator compartment via a fan, while direct cooling involves transferring the cooling energy from the evaporator to the refrigerator compartment via natural convection. Direct cooling uses direct cooling in the refrigerator compartment and air cooling in the freezer compartment. Air cooling, due to the forced convection of the fan, offers higher temperature control accuracy than direct cooling. However, regardless of the cooling method used (air cooling, direct cooling, or air-direct cooling), the refrigerator compartment temperature fluctuates significantly. The main reasons for this are as follows:

[0050] 1. The direct cooling method will cause inaccurate temperature control due to the temperature gradient of natural convection of air;

[0051] 2. Although the air-cooling method uses a fan to blow cold air, when the cooling is stopped, the fan stops running and the cold air sinks, resulting in a temperature difference between the upper and lower parts of the room;

[0052] 3. Due to the natural defrosting of the evaporator of the direct cooling refrigerator or the heating defrosting of the evaporator of the air cooling refrigerator, no cold energy is supplied to the compartment during the defrosting period, causing the compartment temperature to rise and cause the compartment temperature to fluctuate.

[0053] To solve the above problem, in this embodiment, a multi-sensor distributed temperature measurement is adopted. Sensors are arranged in different areas of the compartment. When the refrigerator stops refrigerating, multiple different temperature sensors are used to detect temperature changes at different locations inside the compartment in real time. Specifically, in order to comprehensively detect the temperature of the refrigerator compartment, multiple sensors are distributed as evenly as possible in the compartment to ensure that the temperature at each location in the compartment is detected. Figure 3 Schematic diagram of the dual refrigeration system structure of this embodiment. Figure 3 As shown, the dual refrigeration system in this embodiment includes two refrigeration units and two compartments. The two refrigeration units are located in two independent compartments. One of the two compartments is a refrigeration compartment, and the other can be a refrigeration compartment, a freezer compartment, or a temperature-controlled room. If both are refrigeration compartments, two refrigeration units are installed in the refrigeration compartment. However, for energy saving, the optimal installation solution is to install them in a compartment other than the refrigeration compartment. This allows the refrigeration function of the two compartments to be shared through the installed pipes, and also reduces the layout of the air duct, thereby reducing the air duct space occupied by the refrigerator. The two compartments are connected to each other by the air duct.

[0054] The first refrigeration unit 311 and the plurality of temperature sensors 33 are located in the first chamber 31. The first refrigeration unit 311 includes a first evaporator 312, a first defrost heater 313, a first air outlet 314, a second air outlet 315, a first return air outlet 316, a second return air outlet 317, a first air outlet electric damper 3141, a second air outlet electric damper 3151, a first return air outlet electric damper 3161, a second return air outlet electric damper 3171, and a first refrigeration fan 310.

[0055] The second refrigeration unit 321 and the plurality of temperature sensors 33 are located in the second chamber 32. The second refrigeration unit includes a second evaporator 322, a second defrost heater 323, a third air outlet 324, a fourth air outlet 325, a third return air outlet 326, a fourth return air outlet 327, a third air outlet electric damper 3241, a fourth air outlet electric damper 3251, a third return air outlet electric damper 3261, a fourth return air outlet electric damper 3271, and a second refrigeration fan 320.

[0056] The first air outlet electric damper 3141, the first air outlet 314, the third air outlet 324 and the third air outlet electric damper 3241 are connected in sequence. The first air outlet 314 and the third air outlet 324 are also connected to the air outlet 318 of the first chamber 31.

[0057] The second air outlet electric damper 3151, the second air outlet 315, the fourth air outlet 325 and the fourth air outlet electric damper 3251 are connected in sequence; the second air outlet 315 and the fourth air outlet 325 are also connected to the air outlet 328 of the second chamber 32;

[0058] The first return air outlet electric damper 3161, the first return air outlet 316, the third return air outlet 326 and the third return air outlet electric damper 3261 are connected in sequence. The first return air outlet 316 and the third return air outlet 326 are also connected to the return air outlet 319 of the first chamber 31;

[0059] The second return air outlet electric damper 3171 , the second return air outlet 317 , the fourth return air outlet 327 and the fourth return air outlet electric damper 3271 are connected in sequence. The second return air outlet 317 and the fourth return air outlet 327 are also connected to the return air outlet 329 of the second chamber 32 .

[0060] In addition, the air outlet of the refrigerator compartment air duct is arranged at the upper position of the compartment, or is arranged at the upper position and left and right sides of the compartment at the same time, and the return air outlet of the compartment air duct is arranged at the lower position of the compartment, which is conducive to the circulation of duct air, and the cold air is blown from the upper position or left and right sides of the compartment to the lower position of the compartment.

[0061] Step S202, determining whether there is a temperature greater than or equal to a preset startup temperature among the temperatures at various locations in the compartment; if so, when all temperatures are greater than a preset shutdown temperature, starting the refrigeration unit and the refrigeration fan to cool the compartment.

[0062] Specifically, the start-up temperature and shutdown temperature of a refrigerator refrigeration can be pre-set according to the ambient temperature. For example, the start-up temperature can be set to 6°C and the shutdown temperature can be set to 4°C. The specific settings can be based on actual needs, and this embodiment does not impose specific limitations on this. Determine whether there is a temperature greater than or equal to the preset start-up temperature of 6°C among the temperatures detected by multiple temperature sensors. If so, it means that the temperature of some positions in the compartment is too high and needs to be treated. Then determine whether all the detected temperatures are greater than the preset shutdown temperature of 4°C. If there is a temperature less than the shutdown temperature, it means that the temperature of some positions is still too low. If the refrigeration is turned on at this time, it will cause the position to freeze due to the low temperature, thereby affecting the preservation of food in the compartment. Therefore, on the basis that the detected temperatures are greater than the preset shutdown temperature of 4°C, the refrigeration unit and the refrigeration fan are started to cool the compartment. Among them, starting the refrigeration unit refrigeration is mainly achieved by starting the compressor and switching the solenoid valve to the refrigeration pipeline so that the evaporator of the target refrigeration unit has refrigerant flowing for heat exchange refrigeration. Figure 3 As shown, if one or more of the temperatures detected by the multiple temperature sensors 33 in the first compartment 31 exceeds the preset startup temperature of 6°C, while the temperatures at all other locations are above the preset shutdown temperature of 4°C, if the first refrigeration unit 311 is not in the defrost phase, the first air outlet electric damper 3141 and the first return air outlet electric damper 3161 are opened, and the first refrigeration fan 310 is turned on to control the first refrigeration unit 311 to cool. The first refrigeration fan 310 accelerates the flow of cold air into the first compartment 31 through the first air outlet 314 and the air outlet 318 of the first compartment 31, and then circulates the cold air through the return air outlet 319 and the first return air outlet 316 of the first compartment 31. If the first refrigeration unit is in the defrost phase, all dampers in the first refrigeration unit remain closed, and the second refrigeration unit can be turned on for cooling. The electric damper and air outlet of the second refrigeration unit leading to the first compartment, as well as the second refrigeration fan of the second refrigeration unit, are turned on to cool the first compartment.

[0063] Step S203: When one or more of the temperatures detected at various locations are lower than the preset shutdown temperature, and the temperature difference between the maximum and minimum temperatures at various locations in the compartment is greater than the preset start-up temperature difference threshold, the refrigeration unit is not started, and only the refrigeration fan is turned on to control the refrigeration fan to operate and cool the compartment.

[0064] Specifically, if one or more of the temperatures detected at various locations is 4°C below the preset shutdown temperature, it is not appropriate to turn on the refrigeration unit for cooling. Turning on the refrigeration unit for cooling will cause individual temperatures to drop too low and form ice, affecting the storage temperature of the refrigerated compartment. Turning on the refrigeration unit primarily involves running the compressor and switching the solenoid valve to the refrigeration pipeline, allowing refrigerant to flow through the evaporator of the target refrigeration unit, thereby performing heat exchange cooling. Turning off the refrigeration unit primarily means stopping the compressor or switching the refrigeration pipeline with a solenoid valve, so that no refrigerant flows through the evaporator of the target refrigeration unit for heat exchange. At this time, the temperature difference between the maximum and minimum values ​​of the detected temperatures at each position is further determined, and it is determined whether the calculated temperature difference is greater than a preset temperature difference. The preset temperature difference can be set according to actual needs to achieve a temperature difference for balancing the air in the compartment. For example, the preset temperature difference is 0.5° C. When the temperature difference between the maximum and minimum values ​​of the detected temperatures at each position is greater than the preset temperature difference of 0.5° C., if the first refrigeration unit 311 is not in the defrosting stage, the first air outlet electric damper 3141 and the first return air outlet electric damper 3161 are opened to stop the refrigeration of the first refrigeration unit 311, and the first refrigeration fan 310 is controlled to operate. The first refrigeration fan 310 drives air through the first air outlet 314, the air outlet 318 of the first compartment 31, the return air outlet 319 of the first compartment 31, and the first return air outlet 316 to circulate gas, thereby balancing the temperatures at different positions, achieving temperature balance in the compartment, and solving the problem of uneven temperature distribution in the compartment during the refrigeration stop period. Similarly, if the first refrigeration unit 311 is in the defrosting stage, the second refrigeration unit is controlled to remain in a refrigeration stop state, and the second refrigeration fan in the second refrigeration unit and the damper of the second refrigeration unit to the first compartment are opened. The second refrigeration fan is used to equalize the temperature at various locations in the first compartment, thereby solving the problem of uneven temperature distribution in the compartments during the refrigeration stop period.

[0065] Through the above steps S201 to S203, during the refrigeration stop period, the temperature of each position of the refrigerator compartment is detected in real time by a preset plurality of temperature sensors; it is determined whether there is a temperature greater than or equal to the preset start-up temperature among the temperatures at each position of the compartment; if so, when all temperatures are greater than the preset stop temperature, the refrigeration unit and the refrigeration fan are started to run to cool the compartment; otherwise, when the temperature difference between the maximum and minimum values ​​of the temperature at each position of the compartment is greater than the preset start-up temperature difference threshold, the refrigeration unit is not started, only the refrigeration fan is turned on, and the refrigeration fan is controlled to run to cool the compartment. Compared with the prior art of cooling the compartment by direct cooling, air cooling and air direct cooling, the present application sets multiple temperature sensors at different positions of the compartment to detect the compartment temperature at each position. During the refrigeration period, if the temperature detected by the sensor at one position is greater than or equal to the start-up temperature of the compartment refrigeration, and the temperature detected by all other sensors is greater than the stop temperature of the compartment refrigeration, the refrigeration unit is started to refrigerate and the refrigeration fan is turned on to cool the compartment. When the temperature is lower than the shutdown temperature and the temperature difference at different locations is greater than the preset temperature difference threshold, the refrigeration unit is controlled to stop refrigeration and only the refrigeration fan is turned on to balance the temperature of the compartment, solving the problem of large temperature fluctuations in the refrigerator.

[0066] In some embodiments, the plurality of temperature sensors include an NTC temperature sensor and an infrared temperature sensor, and the NTC temperature sensor and the infrared temperature sensor are placed in a one-to-one correspondence.

[0067] Specifically, in the prior art, refrigerator temperature detection often relies solely on NTC temperature sensors. However, NTC temperature sensors exhibit a certain temperature sensing lag, resulting in delayed temperature detection and an inability to make timely temperature control adjustments. To address this issue, this embodiment employs both an NTC temperature sensor and an infrared temperature sensor to simultaneously detect the refrigerator compartment temperature. The infrared temperature sensor's real-time detection capability mitigates the NTC temperature sensor's temperature sensing lag. Furthermore, the two temperature sensors are placed in corresponding locations to improve the accuracy of temperature detection at those locations.

[0068] In another embodiment, the temperature of each location in the refrigerator compartment is detected in real time by a plurality of preset temperature sensors, including:

[0069] The initial infrared temperature is detected by the infrared temperature sensor; the NTC temperature is detected by the NTC temperature sensor; the initial infrared temperature is corrected according to the NTC temperature to obtain the target infrared temperature. The temperature at each position in the compartment includes the NTC temperature and the target infrared temperature.

[0070] Specifically, although the infrared temperature sensor can detect the temperature of the compartment in real time and solve the problem of temperature lag of the NTC temperature sensor, the infrared temperature sensor has the problem of inaccurate temperature measurement during the detection process. For example, if the position of the food changes, the infrared temperature sensor will detect the food temperature deviation. Therefore, in this embodiment, the detected infrared temperature is first corrected. First, when the temperature of the refrigerator compartment is in a stable state, the initial infrared temperature is detected by the infrared temperature sensor, and the NTC temperature is detected by the NTC temperature sensor. The corresponding relationship between the infrared temperature and the NTC temperature is established. The specific infrared correction calculation method is as follows:

[0071] k=(T ntc_t2 -T ntc_t1 ) / (T r_t2 -T r_t1 );

[0072] T r_cro_ti =T ntc_t1 +k×(T r_ti -T r_t1 );

[0073] Wherein, k is the infrared temperature correction coefficient;

[0074] T ntc_t1 The first NTC temperature in the current temperature stabilization stage;

[0075] T ntc_t2 The second NTC temperature in the current temperature stabilization stage;

[0076] T r_t1 is the first infrared temperature corresponding to the current temperature stabilization stage;

[0077] T r_t2 is the second infrared temperature corresponding to the current temperature stabilization stage;

[0078] T r_ti is the infrared temperature at the i-th moment corresponding to the next temperature stabilization stage;

[0079] T r_cro_ti is the corrected infrared temperature at time ti corresponding to the next temperature stabilization stage.

[0080] The temperature stabilization stage is when the rate of change of the infrared temperature is within a preset rate of change threshold.

[0081] Through the above formula, the initial infrared temperature is corrected by the NTC temperature to obtain the corrected infrared temperature, and the corrected infrared temperature is used to judge the temperature of each position in the compartment. In addition, due to the temperature fluctuation of the compartment, there is a situation where the compartment temperature is not in a stable state. At this time, the correction coefficient of the infrared temperature needs to be recalculated based on the data under the new temperature stable state. When the infrared temperature sensor correction temperature is not obtained, the temperature value detected by the NTC temperature sensor is first used as the temperature data of each position, and the operation of the refrigerator's refrigeration unit and refrigeration fan is controlled according to the NTC temperature. Ensure that the changes in the refrigerator compartment temperature are adjusted in time.

[0082] In some embodiments, when all temperatures are greater than a preset shutdown temperature, the refrigeration unit and the refrigeration fan are started to operate to cool the compartment, and the method further includes:

[0083] Real-time detection of the temperature of each location in the refrigerator compartment;

[0084] When the temperature at each position in the compartment is lower than the preset shutdown temperature, the refrigeration unit and the refrigeration fan are controlled to stop running to stop cooling the compartment.

[0085] Specifically, when it is detected that the temperature of each position is greater than the shutdown point and there is a temperature greater than the startup temperature, the refrigeration unit and the refrigeration fan are turned on to cool the compartment. After a period of cooling, when it is detected that one or more of the temperatures at each position of the compartment are less than the preset shutdown temperature, the refrigeration unit and the refrigeration fan are controlled to stop running and stop cooling the compartment.

[0086] In another embodiment, when the temperature difference between the maximum and minimum values ​​of the temperatures at various locations in the compartment is greater than a preset start-up temperature difference threshold, the refrigeration unit is not started, only the refrigeration fan is turned on, and after the refrigeration fan is controlled to operate to cool the compartment, the method further includes:

[0087] When the temperature difference between the maximum and minimum values ​​of the temperatures at various locations in the compartment is less than a preset stop temperature difference threshold, the refrigeration fan is controlled to stop running and the compartment is stopped from cooling.

[0088] Specifically, when the temperature at each position in the compartment is lower than the preset startup temperature, and the temperature difference between the maximum and minimum values ​​of the temperature at each position in the compartment is greater than the preset startup temperature difference threshold, the refrigeration unit is not started for cooling, only the refrigeration fan and the corresponding damper to the compartment are opened, and the air at different positions is driven by the refrigeration fan to circulate the air and balance the temperature of the compartment until the temperature difference between the maximum and minimum values ​​of the temperature at each position in the compartment is less than the preset stop temperature difference threshold, the refrigeration fan is stopped, and the temperature balancing of the compartment is stopped.

[0089] In some embodiments, the refrigerator includes a first compartment and a second compartment; when the temperature difference between the maximum and minimum values ​​of the temperatures at various locations in the compartment is less than a preset stop temperature difference threshold, controlling the refrigeration fan to stop running and stopping cooling the compartment includes:

[0090] When the temperature difference between the maximum and minimum values ​​of the temperatures at various positions in the first compartment is less than a preset stop temperature difference threshold, determining whether the temperature difference between the maximum and minimum values ​​of the temperatures at various positions in the second compartment is greater than a preset start temperature difference threshold;

[0091] If so, the refrigeration fan is controlled to continue running, the damper of the first chamber is closed, and the damper of the second chamber is opened to cool the second chamber.

[0092] Specifically, such as Figure 3 As shown, the refrigerator in this embodiment includes a first compartment 31 and a second compartment 32. Due to the provision of an air duct between the first and second compartments, after the first refrigeration fan 310 in the first compartment 31 completes temperature equalization in the first compartment 31, the damper of the first refrigeration unit leading to the first compartment is first closed. A determination is then made as to whether the temperature difference between the maximum and minimum values ​​at various locations in the second compartment exceeds a preset start-up temperature difference threshold. If so, the damper of the first refrigeration unit leading to the second compartment is opened, and the first refrigeration fan in the first refrigeration unit equalizes the temperature in the second compartment, thereby cooling the second compartment. Alternatively, if the temperature difference between the maximum and minimum values ​​at various locations in the second compartment exceeds the preset start-up temperature difference threshold, and the second refrigeration unit in the second compartment is not in the defrosting phase, the first refrigeration fan may be turned off and the second refrigeration fan turned on to cool the second compartment.

[0093] In another embodiment, before determining whether the temperature difference between the maximum and minimum values ​​of the temperatures at various locations in the second chamber is greater than a preset start temperature difference threshold, the method further includes:

[0094] Determine whether the refrigeration unit corresponding to the second chamber is in the defrosting stage; if so, control the refrigeration fan to continue running, close the damper of the first chamber, open the damper of the second chamber, and cool the second chamber; otherwise, control the refrigeration fan to stop running, open the refrigeration fan of the second chamber to cool the second chamber.

[0095] Specifically, after the first refrigeration fan completes temperature equalization of the first chamber, it is determined whether the second refrigeration unit of the second chamber is in the defrosting stage. If the second refrigeration unit of the second chamber is not in the defrosting stage, if the second chamber needs to be temperature equalized, the second refrigeration fan of the second chamber can be directly used to perform temperature equalization on the second chamber. At this time, the first refrigeration fan can be turned off. Compared with performing temperature equalization on the second chamber through the first refrigeration fan, directly performing temperature equalization on the second chamber through the second refrigeration fan can reduce the air duct path and speed up the temperature equalization of the second chamber.

[0096] This embodiment also provides a method for adjusting the temperature of a refrigerator compartment. Figure 4 FIG. 1 is a flow chart of another refrigerator compartment temperature adjustment method according to the present embodiment. Figure 4 As shown, the process includes the following steps:

[0097] Step S401: During the refrigeration stop period, the temperature of each position in the first compartment of the refrigerator is detected in real time by using a plurality of preset NTC temperature sensors and infrared temperature sensors;

[0098] Step S402, determining whether there is a temperature greater than or equal to a preset power-on temperature among the temperatures at various locations in the first chamber; if so, executing step S403; otherwise, executing step S411;

[0099] Step S403, determining whether the temperature at each position of the first chamber is greater than the preset shutdown temperature, if so, executing step S404, otherwise executing step S411;

[0100] Step S404: start the first refrigeration unit and the first refrigeration fan to cool the first room;

[0101] Step S405: When the temperature difference between the maximum and minimum values ​​of the temperatures at various locations in the first compartment is less than a preset start-up temperature difference threshold, closing the damper of the first refrigeration unit leading to the first compartment;

[0102] Step S406, determining whether the second chamber needs to be cooled, if so, executing step S407, otherwise executing step S410;

[0103] Step S407, determining whether the second refrigeration unit is in the defrosting stage, if so, executing step S408, otherwise executing step S409;

[0104] Step S408: After determining the temperature of each position in the second chamber according to the above determination method, the first refrigeration unit and the first refrigeration fan are controlled to cool the second chamber;

[0105] Step S409: shut down the first refrigeration unit and the first refrigeration fan, determine the temperature of each position in the second chamber according to the above determination method, and then control the second refrigeration unit and the second refrigeration fan to cool the second chamber;

[0106] Step S410, turning off the first cooling fan;

[0107] Step S411, determining whether the temperature difference between the maximum and minimum values ​​of the temperatures at various locations in the first compartment is greater than a preset start temperature difference threshold; if so, executing step S412; otherwise, executing step S413;

[0108] Step S412: The first refrigeration unit is not started for refrigeration, and only the first refrigeration fan is turned on to cool the first room; until the temperature difference is less than the preset start temperature difference threshold, the first refrigeration fan is stopped, and the cooling is ended;

[0109] Step S413: No cooling process is performed.

[0110] Through the above steps S401 to S413, by setting multiple NTC temperature sensors and infrared temperature sensors at different positions in the compartment, the compartment temperature at each position is detected in real time. During the cooling period, as long as the temperature detected by the sensor at one position is greater than or equal to the start-up temperature of the compartment cooling, and the temperature detected by all other sensors is greater than the shutdown temperature of the compartment cooling, the refrigeration unit and the refrigeration fan are started to cool the compartment. After cooling for a period of time, when the temperature detected by the sensor is less than the temperature of the shutdown point, the refrigeration is stopped. When the temperature at each position is greater than the start-up temperature of the compartment cooling, when the temperature difference between different positions in the compartment exceeds a preset temperature difference threshold, the refrigeration unit is not started for refrigeration, and only the refrigeration fan is turned on to balance the temperature difference between different positions in the compartment. Moreover, through the arrangement of the air duct, the refrigeration unit and refrigeration fan of one compartment can also cool and cool another compartment. This solves the problem of excessive temperature fluctuations in the refrigerator compartment.
