Description

Technical Field

[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 in life and is widely used in 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 in 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 in the refrigeration compartment is not adjusted accordingly in time, it is easy for the refrigeration compartment temperature to be too low in low ambient temperature, causing the food to freeze, or the refrigeration compartment temperature to be too high in high ambient temperature, causing the 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 through a plurality of preset temperature sensors.

[0049] Specifically, the existing refrigerators have three cooling methods: air cooling, direct cooling, and air direct cooling. Air cooling is when the cold energy of the evaporator is blown into the compartment by a fan, and direct cooling is when the cold energy of the evaporator is transferred to the compartment by natural convection of the air. Air direct cooling is when the refrigerator compartment adopts direct cooling, and the freezer compartment adopts air cooling. Air cooling has higher temperature control accuracy than direct cooling due to the forced convection of the fan. However, no matter which cooling method is adopted (air cooling, direct cooling, air direct cooling), there is a problem of large temperature fluctuation in the refrigerator compartment. The main reasons 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 positions in 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 air is supplied to the compartment during the defrosting period, causing the compartment temperature to rise and cause the compartment temperature to fluctuate.

[0053] In order to solve the above problem, in this embodiment, multi-sensor distributed temperature measurement is adopted, and sensors are arranged in different areas of the compartment. When the refrigerator stops refrigerating, temperature changes at different positions inside the compartment are detected in real time by multiple different temperature sensors. In order to comprehensively detect the temperature of the refrigerator compartment, multiple sensors are distributed in the compartment as evenly as possible to ensure that the temperature at each position of 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 compartments respectively and are independent of each other. One of the two compartments is a refrigeration compartment, and the other can be a refrigeration compartment, a freezing compartment, or a temperature-changing compartment. If both are refrigeration compartments, two refrigeration units are set in the refrigeration compartment. However, from the perspective of energy saving, the optimal setting scheme is to set them in other compartments except the refrigeration compartment, so that the refrigeration functions between the compartments can be used interchangeably through the set pipes, and the arrangement of the air duct can also be reduced, thereby reducing the occupied space of the air duct in the refrigerator. The two compartments are connected to each other through the air duct.

[0054] The first refrigeration unit 311 and the plurality of temperature sensors 33 are located in the first room 31. The first refrigeration unit 311 includes a first evaporator 312, a first defrosting 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 comprises a second evaporator 322, a second defrosting 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, and 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, and 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, and 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 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 positions 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 specifically limit 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 the detected temperatures are all 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, which will affect the preservation of food in the compartment. Therefore, on the basis that the detected temperatures are all greater than the preset shutdown temperature of 4°C, start the refrigeration unit and the refrigeration fan to cool the compartment. Among them, starting the refrigeration unit refrigeration is mainly through starting the compressor to operate, switching the solenoid valve to the refrigeration pipeline, so that the evaporator of the target refrigeration unit has refrigerant flowing, and heat exchange refrigeration is performed. Figure 3 As shown, if one or more of the temperatures detected by the multiple temperature sensors 33 in the first compartment 31 is greater than the preset startup temperature of 6°C, and the temperatures at all other locations are greater than the preset shutdown temperature of 4°C, if the first refrigeration unit 311 is not in the defrosting stage at this time, the first air outlet electric damper 3141 and the first return air outlet electric damper 3161 are opened, the first refrigeration fan 310 is turned on, the first refrigeration unit 311 is controlled to refrigerate, and the first refrigeration fan 310 is used to accelerate the cold air to enter the first compartment 31 through the first air outlet 314 and the air outlet 318 of the first compartment 31, and then the cold air is circulated and refrigerated 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 defrosting stage, all dampers in the first refrigeration unit are kept closed, the second refrigeration unit can be turned on for refrigeration, and the electric damper and air outlet of the second refrigeration unit leading to the first compartment and the second refrigeration fan of the second refrigeration unit are turned on, and the first compartment is cooled and cooled by the second refrigeration unit.

[0063] Step S203, when there is one or more temperatures less than the preset shutdown temperature among the temperatures detected at various positions, and when the temperature difference between the maximum and minimum temperatures at various positions in 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 operate to cool the compartment.

[0064] Specifically, if one or more of the temperatures detected at various locations are lower than the preset shutdown temperature of 4°C, it is not appropriate to turn on the refrigeration unit for cooling and cooling. Starting the refrigeration unit for cooling will cause individual temperatures to be too low and freeze, affecting the storage temperature of the cold room. Starting the refrigeration unit is mainly through the operation of the compressor, and switching the solenoid valve to the refrigeration pipeline, so that the evaporator of the target refrigeration unit has refrigerant flowing, thereby performing heat exchange refrigeration; not starting the refrigeration unit mainly means: by stopping the operation of the compressor, or switching the refrigeration pipeline through the solenoid valve, the evaporator of the target refrigeration unit is controlled without refrigerant flowing for heat exchange. At this time, the temperature difference between the maximum value and the minimum value of the temperature at each position detected is further determined, and it is determined whether the calculated temperature difference is greater than a preset temperature difference, wherein the preset temperature difference can be set according to actual needs, and the temperature difference for balancing the air in the compartment is set, for example, the temperature difference is set to 0.5°C. When the temperature difference between the maximum value and the minimum value of the temperature at each position detected 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, the refrigeration of the first refrigeration unit 311 is stopped, and the first refrigeration fan 310 is controlled to run, and the first refrigeration fan 310 drives the air to circulate 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 balance the temperatures at different positions, achieve temperature balance in the compartment, and solve 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 keep the refrigeration stopped, the second refrigeration fan in the second refrigeration unit and the air door of the second refrigeration unit to the first compartment are opened, and the temperature of each position in the first compartment is balanced by the second refrigeration fan, so as to solve the problem of uneven temperature distribution in the compartment during the refrigeration stop period.

[0065] Through the above steps S201 to S203, during the period of stopping refrigeration, the temperature of each position of the refrigerator compartment is detected in real time through a plurality of preset temperature sensors; it is determined whether there is a temperature greater than or equal to the preset startup temperature among the temperatures of each position of the compartment; if so, when all temperatures are greater than the preset shutdown temperature, the refrigeration unit and the refrigeration fan are started to cool the compartment; otherwise, when the temperature difference between the maximum value and the minimum value of the temperature at each position of the compartment is greater than the preset startup temperature difference threshold, the refrigeration unit is not started, only the refrigeration fan is turned on, and the refrigeration fan is controlled to operate to cool the compartment. Compared with the prior art that cools the compartment by direct cooling, air cooling and air direct cooling alone, the present application sets a plurality of 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 startup temperature of the compartment refrigeration, and the temperature detected by all other sensors is greater than the shutdown 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 of the 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, only NTC temperature sensors are often used to detect refrigerator temperature. However, NTC temperature sensors have a certain temperature sensing lag when detecting temperature, resulting in untimely temperature detection and failure to make timely temperature control adjustments to the refrigerator. To solve this problem, in this embodiment, NTC temperature sensors and / or infrared temperature sensors are used to simultaneously detect the temperature of the refrigerator compartment, and the temperature sensing lag of NTC temperature sensors is solved by the real-time detection of infrared temperature sensors. In addition, two temperature sensors are placed one by one in different positions to improve the accuracy of temperature detection at the position.

[0068] In another embodiment, the temperature of each position of the refrigerator compartment is detected in real time by using 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, and the temperature at each position of 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 to 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 temperature of the food and there will be deviations. Therefore, in this embodiment, the infrared temperature detected is corrected first. 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] Where 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 It is the corrected infrared temperature at the moment 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 range.

[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 determine 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, and after the compartment is cooled down, 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 of 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 at 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 cooling for a period of time, 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 positions 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 positions 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 down.

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

[0089] In some embodiments, the refrigerator includes a first compartment and a second compartment; when the temperature difference between the maximum value and the minimum value of the temperature at each position of 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, including:

[0090] When the temperature difference between the maximum value and the minimum value of the temperature at each position of the first chamber is less than the preset stop temperature difference threshold, determine whether the temperature difference between the maximum value and the minimum value of the temperature at each position of the second chamber is greater than the 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, Figure 3 As shown, the refrigerator in this embodiment includes a first compartment 31 and a second compartment 32. By setting the air duct between the first compartment and the second compartment, after the first refrigeration fan 310 in the first compartment 31 completes the temperature balance of the first compartment 31, the air door of the first refrigeration unit leading to the first compartment is first closed, and it is determined whether the temperature difference between the maximum value and the minimum value of the temperature at each position in the second compartment is greater than the preset start-up temperature difference threshold. If so, the air door of the first refrigeration unit leading to the second compartment is opened, and the temperature of the second compartment is balanced by the first refrigeration fan in the first refrigeration unit, so as to cool the second compartment. In addition, when the temperature difference between the maximum value and the minimum value of the temperature at each position in the second compartment is greater than the preset start-up temperature difference threshold, the second refrigeration unit in the second compartment is not in the defrosting stage at this time, and the first refrigeration fan can also be closed, and the second refrigeration fan can be opened to cool the second compartment.

[0093] In another embodiment, before determining whether the temperature difference between the maximum value and the minimum value of the temperatures at various positions of 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 balancing 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 temperature balancing, the temperature of the second chamber can be directly balanced by the second refrigeration fan of the second chamber. At this time, the first refrigeration fan can be turned off. Compared with temperature balancing of the second chamber by the first refrigeration fan, directly performing temperature balancing of the second chamber by the second refrigeration fan can reduce the air duct path and speed up the temperature balancing 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 of this embodiment. Figure 4 As shown, the process includes the following steps:

[0097] Step S401, during the refrigeration stop period, the temperature of each position of 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 startup temperature among the temperatures at various positions of 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, starting 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 positions 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 yes, 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 judging the temperature of each position in the second chamber according to the above judgment method, controlling the first refrigeration unit and the first refrigeration fan to cool the second chamber;

[0105] Step S409, shutting down the operation of the first refrigeration unit and the first refrigeration fan, judging the temperature of each position in the second chamber according to the above judgment method, and controlling 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 value and the minimum value of the temperature at each position of the first chamber is greater than a preset start temperature difference threshold, if so, executing step S412, otherwise, executing step S413;

[0108] Step S412: do not start the first refrigeration unit to operate for refrigeration, only turn on the first refrigeration fan to cool the first room; until the temperature difference is less than the preset start temperature difference threshold, stop the operation of the first refrigeration fan; end the cooling;

[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 of the compartment, the compartment temperature at each position is detected in real time. During the refrigeration 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 refrigeration, and the temperature detected by all other sensors is greater than the shutdown temperature of the compartment refrigeration, the refrigeration unit and the refrigeration fan are started to cool the compartment. After refrigeration 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 refrigeration, when the temperature difference at different positions in the compartment exceeds the preset temperature difference threshold, the refrigeration unit is not started to operate the refrigeration, and only the refrigeration fan is turned on to balance the temperature difference at different positions of the compartment. And through the arrangement of the air duct, the refrigeration unit and the refrigeration fan in one compartment can also cool and cool another compartment. The problem of excessive temperature fluctuation in the refrigerator compartment is solved.
