[0002] As the functions of refrigerators increase, more and more refrigerators are equipped with variable temperature chambers. Users can set different storage temperatures for different ingredients in the variable temperature chamber to maximize the freshness and nutrition of the ingredients.

[0003] Since the adjustable temperature range of the variable temperature chamber is large, when the temperature is set to the temperature range of the refrigerator, the variable temperature chamber can be used as a refrigerator, and when the temperature is set to the temperature range of the freezer, the variable temperature chamber can also be used as a freezer.

[0004] However, if the current temperature of the variable temperature chamber is low, for example, when the temperature of the variable temperature chamber is the temperature of the freezer, when the user adjusts the temperature of the variable temperature chamber to a higher temperature, for example, to the temperature of the refrigerator, the temperature of the refrigerator rises slowly, so that the temperature rise takes a long time, which is inconvenient for users. Summary of the invention

[0005] The embodiments of the present application provide a refrigerator, a refrigerator temperature control method and a storage medium, which can be used to solve the problem in the related art that when a user adjusts the temperature of the variable temperature chamber to a higher temperature, the temperature of the refrigerator rises slowly, so that it takes a long time to raise the temperature.

Then, the first gear of the variable temperature chamber corresponding to the first temperature and the second gear of the variable temperature chamber corresponding to the second temperature are determined, and then, according to one or more of the first gear, the second gear, the first temperature and the second temperature, it is determined whether to turn on the first defrost heater to provide heat for the variable temperature chamber.

[0074] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0075] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0076] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0077] At present, the adjustable temperature range of the variable temperature chamber is relatively large, for example, -20℃~5℃. When the temperature is set to the temperature range of the refrigerator, for example, 0℃~5℃, the variable temperature chamber can be used as a refrigerator. When the temperature is set to the temperature range of the freezer, for example, -20℃~-5℃, the variable temperature chamber can also be used as a freezer.

[0078] However, if the current temperature of the variable temperature chamber is low, and the user adjusts the temperature of the variable temperature chamber to a higher temperature, the temperature of the refrigerator rises slowly, so that it takes a long time to raise the temperature, which is inconvenient for the user.

[0079] Moreover, the variable temperature chamber is generally close to the freezer, and the set temperature of the freezer and the thickness of the foam layer around the variable temperature chamber have a great influence on the temperature of the variable temperature chamber. When the variable temperature chamber is used as a cold storage room, the food is easily frozen in the variable temperature chamber because it is affected by factors such as the ambient temperature of the refrigerator.

[0080] Therefore, the present application provides a refrigerator, which detects whether the gear position of the variable temperature chamber is adjusted from a low gear to a high gear, and determines whether the compartment temperature of the variable temperature chamber is too low when the variable temperature chamber is used as a refrigeration chamber. If so, the defrost heater of the evaporator of the variable temperature chamber provides heat to the variable temperature chamber, thereby increasing the heating speed of the variable temperature chamber and shortening the time it takes for the variable temperature chamber to heat up from a low temperature to a high temperature.

[0081] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0082] First, the specific structure of a refrigerator provided in an embodiment of the present application is described. For example, Figure 1 A schematic diagram of a refrigerator provided in an embodiment of the present application, Figure 2 A schematic diagram of another refrigerator provided in an embodiment of the present application, such as Figure 1 and Figure 2 As shown, the refrigerator 10 includes a body 101, a door 102 and a storage chamber arranged in the body 101, and the storage chamber includes a refrigerating chamber 11, a temperature-changing chamber 12 and a freezing chamber 13. Figure 1 The refrigerating chamber 11, the temperature-changing chamber 12 and the freezing chamber 13 are arranged in an upper-middle-lower structure in the refrigerator. Figure 2 The upper chamber is a refrigerating chamber 11, and the lower chamber is divided into a temperature-changing chamber 12 and a freezing chamber 13. Figure 1 and Figure 2 This is only a schematic diagram of a refrigerator applicable to the present application. It may also be a refrigerator with other structures, and the present application does not impose any limitation on this.

[0083] Figure 3 A schematic diagram of the structure of a refrigerator provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the refrigerator 10 includes a compressor (not shown in the figure), a first evaporator 14 , a first defrosting heater 15 , a first temperature sensor 16 and a control component 103 .

[0084] Among them, the compressor 103 is arranged in the box body 101 of the refrigerator 10, and the first evaporator 14, the first defrost heater 15 and the first temperature sensor 16 are all arranged in the box body 101. Specifically, the first defrost heater 15 is arranged on one side of the first evaporator 14. The first evaporator 14 can output cold air for the variable temperature chamber 12. The first defrost heater 15 is configured to remove the frost layer on the first evaporator 14 and provide heat for the variable temperature chamber 12. Specifically, the control component 103 can control the first defrost heater 15 to turn on, so as to remove the frost layer on the first evaporator 14, or provide heat for the variable temperature chamber 12.

[0085] The first temperature sensor 16 is disposed in the temperature changing chamber 12 of the refrigerator, and is configured to detect the temperature of the temperature changing chamber 12 .

[0086] The control component 103 is disposed in the box 101, and the control component 103 is connected to the first temperature sensor 16, and specifically, can be electrically connected. Exemplarily, the control component 103 can be a microcontroller unit (MCU).

[0087] The control component 103 is configured to: obtain the first temperature and the second temperature detected by the first temperature sensor 16, then determine the first gear of the variable temperature chamber corresponding to the first temperature and the second gear of the variable temperature chamber corresponding to the second temperature, and determine whether to turn on the first defrost heater 15 to provide heat for the variable temperature chamber 12 according to one or more of the first gear, the second gear, the first temperature and the second temperature. The first temperature and the second temperature are respectively detected by the first temperature sensor 16 at different times, and the detection time of the second temperature is the current time.

[0088] That is to say, the second temperature is detected by the first temperature sensor 16 at the current moment, and the first temperature is detected by the first temperature sensor 16 before the current moment. For example, the first temperature can be detected by the first temperature sensor 16 before a preset time at the current moment. For example, the preset time can be 10 minutes.

[0089] In a possible implementation, the control component 103 may detect the temperature once through the first temperature sensor 16 at a preset time interval, and the detection interval between the first temperature and the second temperature is a preset time interval.

[0090] For example, after the refrigerator 10 is powered on and reaches a stable operating state, the first temperature sensor 16 can detect the temperature of the variable temperature chamber 12 once every preset time. The stable operating state is when the temperature of each compartment reaches the temperature threshold for automatically stopping refrigeration. Specifically, the control component 103 can send a detection instruction to the first temperature sensor 16 every preset time, and the first temperature sensor 16 detects the temperature of the variable temperature chamber 12 after receiving the detection instruction.

[0091] In one possible implementation, Figure 4 A schematic diagram of the structure of another refrigerator provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the refrigerator 10 may further include a fan 17, which is configured to allow air to enter the first evaporator 14 for heat exchange and send the heat-released air to the variable temperature chamber 12, thereby increasing the heating rate of the variable temperature chamber.

[0092] In one possible implementation, Figure 4 As shown, the refrigerator 10 may further include a second temperature sensor 18 , which is disposed on one side of the first defrost heater 15 , that is, the second temperature sensor 18 may be disposed near the first defrost heater 15 , so that the second temperature sensor 18 may detect the temperature of the first defrost heater 15 .

[0093] In one possible implementation, Figure 5 A schematic diagram of the structure of another refrigerator provided in an embodiment of the present application is shown in FIG. Figure 5As shown, the refrigerator 10 may also include a second evaporator 19 arranged in the box body 101 and a second defrost heater 20 arranged on one side of the second evaporator. The second evaporator 19 outputs cold air to the refrigerating chamber 11, and the second defrost heater 20 is configured to remove the frost layer on the second evaporator 19.

[0094] That is to say, an independent evaporator and defrost heater can be separately provided for the variable temperature chamber 12. Then, a separate evaporator and defrost heater need to be provided for the refrigerating chamber 11, which can effectively improve the effect of the heat heated by the variable temperature chamber 12 on the refrigerating chamber 11 without affecting the food storage in other chambers.

[0095] In one possible implementation, Figure 6 A schematic diagram of the structure of another refrigerator provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the refrigerator 10 may also include a third evaporator 21 arranged in the cabinet 101 and a third defrost heater 22 arranged on one side of the third evaporator 21. The third evaporator 21 outputs cold air to the freezer chamber 13, and the third defrost heater 22 is configured to remove frost on the third evaporator.

[0096] That is to say, an independent evaporator and a defrost heater can be separately provided for the variable temperature chamber 12, and a separate evaporator and a defrost heater can be separately provided for the freezing chamber 13, which can effectively improve the effect of the heat heated by the variable temperature chamber 12 on the freezing chamber 13 without affecting the food storage in other chambers.

[0097] Alternatively, the same evaporator and defrost heater may be provided for the refrigerating chamber 11 and the freezing chamber 13, and this application does not impose any limitation on this.

[0098] It can be understood that the first defrost heater 15 is only used to defrost the first evaporator 14, that is, the first defrost heater 15 cannot defrost the second evaporator 19 and the third evaporator 21 to avoid affecting the refrigeration of other compartments during defrosting.

[0099] Based on the above refrigerator, Figure 7 A flow chart of a method for controlling the temperature of a refrigerator provided in an embodiment of the present application, the method can be executed by a control component of the refrigerator, such as Figure 7 As shown, the method comprises the following steps:

[0100] S701: Acquire a first temperature and a second temperature detected by a first temperature sensor.

[0101] The control component can obtain the first temperature and the second temperature detected by the first temperature sensor. Exemplarily, the acquisition method can refer to the above embodiment and will not be repeated here.

[0102] S702, determining a first gear of the variable temperature chamber corresponding to the first temperature, and a second gear of the variable temperature chamber corresponding to the second temperature.

[0103] After acquiring the first temperature and the second temperature, the control component may determine a first gear position corresponding to the first temperature and a second gear position corresponding to the second temperature.

[0104] In a possible implementation, the gear of the variable temperature chamber may be set to 0, 1, 2, ..., n gears, for example, where n is an integer greater than 2. When the variable temperature chamber is in different gears, the compartment temperature of the variable temperature chamber is different. For example, the higher the gear, the higher the corresponding temperature, and the lower the gear, the lower the corresponding temperature. The user can adjust the gear of the variable temperature chamber to adjust the temperature of the variable temperature chamber.

[0105] For example, the temperature corresponding to level 0 may be -20 degrees, the temperature corresponding to level 1 may be -19 degrees, and so on.

[0106] For another example, the temperature range corresponding to level 0 may be -20°C (degrees Celsius) to -16°C, the temperature range corresponding to level 1 may be -15°C to -10°C, and so on.

[0107] If the first gear and the second gear are different, it means that the user has adjusted the gear of the temperature-changing chamber.

[0108] It can be understood that the first gear is the gear of the variable temperature room when the first sensor measures the first temperature, and the second gear is the gear of the variable temperature room when the first sensor measures the second temperature.

[0109] S703: Determine whether to turn on the first defrost heater to provide heat for the temperature-changing chamber according to one or more of the first gear position, the second gear position, the first temperature and the second temperature.

[0110] After determining the first temperature, the second temperature, the first gear and the second gear, the control component can determine whether to turn on the first defrost heater according to one or more of the first temperature, the second temperature, the first gear and the second gear.

[0111] In one possible implementation, whether the gear of the variable temperature chamber is adjusted from a low gear to a high gear can be determined based on the first gear, the second gear and the second temperature, wherein the temperature corresponding to the low gear can be lower than the temperature corresponding to the high gear, thereby achieving the provision of heat to the variable temperature chamber through the first defrost heater when the variable temperature chamber is adjusted from a low temperature to a high temperature.

[0112] In another possible implementation, whether the variable temperature chamber is used as a refrigerating chamber when in the first position can be determined based on the first position and the first temperature, thereby providing heat to the variable temperature chamber through the first defrost heater to prevent food in the refrigerating chamber from being frozen.

[0113] In this embodiment, by obtaining the first temperature and the second temperature detected by the first temperature sensor, the first temperature and the second temperature are respectively detected by the first temperature sensor at different times, and the detection time of the second temperature is the current time, then determining the first gear of the variable temperature chamber corresponding to the first temperature and the second gear of the variable temperature chamber corresponding to the second temperature, and then determining whether to turn on the first defrost heater to provide heat for the variable temperature chamber according to one or more of the first gear, the second gear, the first temperature and the second temperature. The present application can shorten the time it takes for the variable temperature chamber to heat up from a low temperature to a high temperature by controlling the defrost heater of the variable temperature chamber.

[0114] Next, the control component will be described as to whether to use the first defrost heater as a refrigerating chamber when the variable temperature chamber is in the first gear position, thereby controlling whether the first defrost heater is turned on.

[0115] Figure 8 A flow chart of another refrigerator temperature control method provided in an embodiment of the present application, which can be executed by a control component, such as Figure 8 As shown, the method includes the following steps.

[0116] S801. Obtain a first temperature and a first gear position.

[0117] S802: Determine whether the first gear is within the gear range corresponding to the refrigerating chamber.

[0118] For example, the temperature range of the variable temperature room is 9, that is, 0, 1, ..., 8, wherein the temperature range corresponding to 0 can be -20℃ (Celsius) ~ -18℃, the temperature range corresponding to 1 can be -17℃ ~ -15℃, the temperature range corresponding to 2 can be -14℃ ~ -12℃, the temperature range corresponding to 3 can be -11℃ ~ -9℃, the temperature range corresponding to 4 can be -8℃ ~ -6℃, the temperature range corresponding to 5 can be -5℃ ~ -3℃, the temperature range corresponding to 6 is -2℃ ~ 1℃, the temperature range corresponding to 7 is 2℃ ~ 3℃, and the temperature range corresponding to 8 is 4℃ ~ 6℃. Then, the temperature range corresponding to the variable temperature room as a refrigerating room can be 7 or 8, and the control component can determine whether the first gear is any one of 7 and 8. If so, it can be determined that the first gear is within the gear range corresponding to the refrigerating room, and if not, it can be determined that the first gear is not within the gear range corresponding to the refrigerating room.

[0119] It can be understood that the above-mentioned gears and temperatures are only examples and can be set according to actual conditions. This application does not limit this.

[0120] If the first gear is within the gear range corresponding to the refrigerating chamber, execute S502. If the first gear is not within the gear range corresponding to the refrigerating chamber, the control component can determine whether the user adjusts the gear of the variable temperature chamber from a low gear to a high gear based on the first gear and the second gear. For details, please refer to the following embodiments.

[0121] S803: Determine whether the first temperature is above a first preset threshold.

[0122] If the first temperature is not above the first preset threshold, S804 is executed. If the first temperature is above the first preset threshold, the control component can continue to detect the temperature of the variable temperature chamber through the first temperature sensor.

[0123] Exemplarily, the first preset threshold value may be 1°C. If the first temperature is not above the first preset threshold value, it means that the temperature of the variable temperature chamber is low, that is, lower than 1°C, and food may be easily frozen. If the first temperature is above the first preset threshold value, it means that the temperature of the variable temperature chamber is normal, that is, it is at the temperature of a refrigerator.

[0124] S804, turn on the first defrost heater.

[0125] If the first temperature is not above the first preset threshold, the control component can control the first defrost heater to turn on, so as to increase the temperature of the variable temperature chamber and prevent the food from freezing.

[0126] In this embodiment, it can be determined whether the variable temperature chamber is used as a refrigerator when it is in the first gear. If so, it is determined whether the first temperature is low. If so, the first defrost heater is turned on to provide heat to the variable temperature chamber to prevent the variable temperature chamber from freezing food due to the low temperature when used as a refrigerator.

[0127] Next, it is described how to determine whether the gear of the temperature-changing chamber is adjusted from a low gear to a high gear according to the first gear, the second gear and the second temperature, thereby controlling whether the first defrost heater is turned on.

[0128] Fig. 9 A flow chart of another refrigerator temperature control method provided in an embodiment of the present application, which can be executed by a control component, such as Fig. 9 As shown, the method includes the following steps.

[0129] S901. Obtain a first gear position, a second gear position, and a second temperature.

[0130] S902: Determine whether the first gear is within the gear range corresponding to the refrigerating chamber.

[0131] If the first gear is not within the gear range corresponding to the refrigerating chamber, execute S903. If the first gear is within the gear range corresponding to the refrigerating chamber, the control component can control the first defrost heater to turn on based on determining whether the variable temperature chamber is lower. For details, please refer to the above embodiment.

[0132] S903: Determine whether the second gear is greater than the first gear.

[0133] If the second gear is greater than the first gear, execute S904. If the second gear is not greater than the first gear, it means that the user has not adjusted the gear of the variable temperature chamber from a low gear to a high gear. Then the control component can continue to monitor the temperature of the variable temperature chamber through the first temperature sensor.

[0134] S904: Determine a first difference between the second temperature and the startup temperature.

[0135] In a possible implementation, the second position is configured with a start-up temperature, which is a temperature threshold for automatically starting cooling when the variable temperature chamber is in the second position. That is, after the user adjusts the temperature of the variable temperature chamber to the second position, the temperature of the variable temperature chamber reaches the start-up temperature, and the variable temperature chamber automatically starts cooling, so that the temperature of the variable temperature chamber is maintained at the temperature corresponding to the second position.

[0136] The control component can determine the temperature difference between the second temperature and the startup temperature, that is, the first difference, so as to judge whether the temperature difference is large. If so, the first defrost heater can be turned on to improve the heating efficiency of the variable temperature chamber.

[0137] S905: Determine whether the first difference is above a second preset threshold.

[0138] If the first difference is above the second preset threshold, S906 is executed. If the first difference is not above the second preset threshold, the control component can continue to monitor the temperature of the variable temperature chamber through the first temperature sensor.

[0139] The control component can determine whether the first difference is above a second preset threshold, thereby determining whether the temperature difference between the second temperature and the startup temperature is large. For example, the second preset threshold can be 10°C.

[0140] S906: Turn on the first defrost heater.

[0141] If the first difference is above the second preset threshold, it means that the temperature difference between the second temperature and the start-up temperature is large, then the control component can control the first defrost heater to turn on, so that the temperature of the variable temperature chamber quickly reaches the temperature threshold for automatically starting refrigeration in the second gear.

[0142] In this embodiment, if the variable temperature chamber is not used as a refrigerating chamber, it can be determined whether the second gear is greater than the first gear, that is, whether the user adjusts from a low gear to a high gear. If so, it is determined whether the temperature difference between the second temperature and the power-on temperature is large. If so, the first defrost heater can be turned on to accelerate the temperature recovery of the variable temperature chamber so that the temperature of the variable temperature chamber quickly reaches the temperature threshold of the second gear for automatically starting refrigeration.

[0143] Next, it is explained how the control component further accelerates the temperature rise of the temperature changing chamber after the first defrost heater is turned on.

[0144] Fig.10 The present application provides another refrigerator temperature control method flow chart, the method can be executed by the control component, such as Fig.10 As shown, the method includes the following steps.

[0145] S1001. After the first defrost heater is turned on, obtain a third temperature of the first defrost heater at a preset time interval.

[0146] After the first defrost heater is turned on, the control component can obtain the third temperature of the first defrost heater at a preset time interval. For example, the preset time interval can be 1 minute, that is, the control component can obtain the temperature of the first defrost heater every 1 minute.

[0147] Specifically, the control component may send a detection instruction to the second temperature sensor, and the second temperature sensor may detect the temperature of the first defrost heater after receiving the detection instruction to obtain the third temperature.

[0148] Alternatively, the second temperature sensor may detect the temperature of the first defrost heater in real time, and when the temperature of the first defrost heater changes, the second temperature sensor may send the corresponding temperature to the control component.

[0149] S1002: Determine a second difference between the third temperature and the startup temperature.

[0150] Under normal circumstances, when the heat exchange temperature difference reaches above a certain temperature, the basic heat exchange efficiency can be met, such as heating or cooling.

[0151] The control component can determine the temperature difference between the third temperature and the startup temperature, that is, the second difference.

[0152] S1003: Determine whether the second difference is above a third preset threshold.

[0153] Exemplarily, the third preset threshold value may be 5°C, and the control component may determine whether the second difference is above the third preset threshold value. If so, it indicates that the heat exchange efficiency is relatively high at this time. Then, the control component may control the fan to turn on, so that air enters the first evaporator for heat exchange and sends the heat-released air to the temperature-changing chamber, so that the temperature of the temperature-changing chamber recovers quickly.

[0154] If the second difference is above the third preset threshold, then S1004 is executed. If the second difference is not above the third preset threshold, then S1001 is executed.

[0155] S1004. Turn on the fan.

[0156] In a possible implementation, after the fan is turned on, the control component can obtain the fourth temperature of the first temperature sensor and determine whether the fourth temperature reaches the shutdown temperature. If the fourth temperature reaches the shutdown temperature, the fan and the first defrost heater are controlled to stop running. Exemplarily, the control component can obtain the fourth temperature of the first temperature sensor at a preset time interval.

[0157] In this embodiment, after turning on the defrost heater, when the temperature difference between the start-up temperature and the temperature of the defrost heater is large, the fan can be turned on to improve the heat exchange efficiency so that the temperature of the variable temperature chamber quickly reaches the start-up temperature to start the cooling of the variable temperature chamber in the second gear.
