[0053] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0054] During the wine preservation process, there may be various situations, for example, the external environment temperature is higher than the wine cabinet temperature; for another example, the external environment temperature is lower than the wine cabinet temperature.

[0055] When the outside environment temperature is higher than the target temperature of the wine cabinet, the ambient temperature in different seasons and regions varies significantly. For example, in high temperature areas in summer, the ambient temperature may reach 35°C or even higher, while the target temperature of the wine cabinet is up to 18°C. At this time, the refrigeration system needs to overcome the large temperature difference and quickly reduce the temperature in the wine cabinet. The higher the ambient temperature, the faster the heat conduction of the wine cabinet wall and other parts. The refrigeration system needs to continue to work at a high intensity to maintain a low temperature, which is a great test for the performance and stability of the refrigeration system.

[0056] At the same time, in a high temperature environment, it becomes difficult for the refrigeration system to dissipate heat itself. The compressor and other refrigeration components will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the temperature of the components will rise, affecting the refrigeration efficiency and may even be damaged due to overheating. The surrounding high temperature environment will make the temperature of the heat dissipation medium, such as air or coolant, also higher, further increasing the difficulty of heat dissipation.

[0057] When the outside ambient temperature is lower than the temperature of the wine cabinet, for example, it may reach below 0°C in the cold winter, and the wine cabinet needs to maintain the temperature above 5°C. At this time, the compensatory heating power needs to be accurately calculated. The lower the ambient temperature, the greater the required heating power. However, if the heating power is too large, the temperature may rise too quickly and exceed the target temperature. If the power is too small, the temperature cannot be raised in time, making it difficult to meet the temperature control requirements.

[0058] And during the compensatory heating process, the temperature inside the wine cabinet must rise evenly to avoid local overheating. Because there are different areas and structures inside the wine cabinet, the position of the heating element and the way heat is transmitted will affect the temperature distribution. If the heating is uneven, some wines may be in an overly high temperature environment, affecting the quality.

[0059] In the process of detecting the temperature in the wine cabinet, the temperature sensor is used for detection. The temperature sensor is a key component for controlling refrigeration and heating. Its accuracy affects the accuracy of temperature control. If the sensor accuracy is not enough, for example, the measurement error is around ±2°C, it may cause the actual temperature to be close to the target temperature. It may still be judged that cooling or heating is needed, thereby triggering unnecessary cooling or heating operations and increasing the possibility of alternating operation.

[0060] When the temperature inside the wine cabinet changes due to cooling or heating, the temperature sensor cannot immediately reflect the actual temperature, which may cause cooling or heating operations to continue when the temperature has reached near the target value. By the time the sensor detects the temperature change and sends a stop signal, the temperature has deviated a lot from the target value, triggering reverse cooling or heating operations, resulting in energy waste.

[0061] It takes a certain amount of time for the refrigeration system to start up and achieve a stable cooling effect, that is, there is a response speed problem. When the ambient temperature rises suddenly, after the refrigeration is started, the temperature inside the wine cabinet may still rise when the cooling capacity has not yet reached enough to balance the heat input. At this time, the refrigeration power may continue to increase. When the cooling capacity begins to exceed the heat input, the temperature will drop too quickly, resulting in the need to frequently adjust the refrigeration power or even compensatory heating to balance, increasing energy consumption and operating burden.

[0062] The heating system also has problems with response speed and inertia. When compensatory heating is needed, after the heating element starts working, it takes time for the heat to be transferred and the temperature in the wine cabinet to rise. Overheating may occur, and cooling is required to adjust the temperature, resulting in energy waste and unstable operation.

[0063] The external ambient temperature is constantly changing, and the changes are uncertain. Large temperature fluctuations may occur in a short period of time. For example, the temperature is higher during the day and lower at night. Frequent temperature changes require the wine cabinet to constantly adjust the cooling and heating strategies. If such changes cannot be accurately predicted and adapted, frequent alternations between cooling and heating will result.

[0064] Other factors such as ambient humidity can also affect heat exchange and temperature control in wine cabinets. For example, in a high humidity environment, condensation will occur on the walls of the wine cabinet, affecting the efficiency of heat transfer. A low humidity environment will cause the air in the wine cabinet to be dry, affecting the storage conditions of the wine. It may also have an indirect impact on temperature control, making the control of cooling and heating more complicated and increasing the difficulty of avoiding alternating operation.

[0065] In some embodiments, a high-precision temperature sensor and control system may be used. For example, a platinum resistance temperature sensor may be used, and its accuracy may reach ±0.1°C, which can more accurately monitor the temperature inside the box. At the same time, algorithms such as fuzzy control and PID control may be used to accurately adjust the operation of the refrigeration and heating equipment according to the temperature information fed back by the sensor.

[0066] However, even with high-precision sensors, it is difficult to completely eliminate the impact of environmental factors, such as uneven temperature fields and humidity changes, on temperature measurement. Temperature control deviations may still occur in extreme environments.

[0067] In other embodiments, monitoring sensors for ambient temperature, humidity, etc. may be installed outside the wine cabinet to obtain real-time external environmental information, and combined with weather data or ambient temperature prediction models, predict the trend of ambient temperature changes, so as to adjust the cooling or heating strategy in advance. For example, when it is predicted that the external temperature is about to rise sharply, the temperature inside the cabinet is lowered in advance or the operating power of the refrigeration system is increased.

[0068] However, there are certain errors in environmental monitoring data and prediction models. For example, short-term extreme weather changes are difficult to accurately predict. Moreover, even if the ambient temperature changes can be accurately predicted, the thermal inertia and complex heat exchange process inside the wine cabinet also limit the effectiveness of the advance adjustment strategy, making it difficult to accurately match the actual temperature change requirements.

[0069] In some embodiments, the refrigeration system can be set to start the refrigeration and cooling temperature points and the refrigeration and cooling end temperature points, and the compensation heating start temperature point and the compensation heating end temperature point of the compensation heating system can also be set, wherein the compensation heating start temperature point is equal to the refrigeration and cooling end temperature point, and the compensation heating end temperature point is equal to the refrigeration and cooling start temperature point. The refrigeration and cooling and compensation heating responses can be timely and without lag, and the temperature control can be accurate. However, after the refrigeration and cooling are completed, the compensation heating will be immediately turned on, and after the compensation heating is completed, the refrigeration and cooling will also be immediately turned on. The alternating and repeated operation of refrigeration and cooling and compensation heating will lead to serious energy waste.

[0070] In other embodiments, a wine cabinet includes a refrigeration device and a heating device, and the temperature control method includes: obtaining the external ambient temperature of the wine cabinet; when the difference between the external ambient temperature and the set temperature of the wine cabinet is greater than or equal to a first preset value, the refrigeration device is controlled to be turned on or off, and the heating device is not allowed to be turned on; when the difference between the external ambient temperature and the set temperature of the wine cabinet is less than or equal to a second preset value, the heating device is controlled to be turned on or off, and the refrigeration device is not allowed to be turned on; wherein the first preset value is a positive number, and the second preset value is a negative number. The advantage of this embodiment of the invention is that it solves the technical problem of the phenomenon that the temperature control refrigeration and heating of the wine cabinet are turned on synchronously, and has an energy-saving effect. The disadvantage of the implementation scheme of the invention is that when the ambient temperature is high, the compensation heater is forced to turn off, and when the ambient temperature is low, the refrigeration device is forced to turn off. In complex user scenarios, it is not conducive to quickly achieving the target set temperature, and the temperature control is correspondingly delayed, and the temperature control accuracy is poor.

[0071] In summary, it is impossible to accurately control refrigeration and cooling and compensating heating to achieve precise temperature control, and refrigeration and cooling and compensating heating are operated alternately and repeatedly, resulting in low energy utilization efficiency.

[0072] To solve the above-mentioned problem, some embodiments of the present application provide a method for controlling the temperature of a wine cabinet. The method compares the target temperature with the ambient temperature and sets different heating or cooling rules based on the comparison results. The method can promptly and accurately respond to the cooling demand and compensatory heating demand of the wine cabinet under different ambient temperatures, thereby achieving precise temperature control. It can also solve the problem of low energy utilization efficiency caused by repeated alternation of cooling and cooling and compensatory heating, that is, the compensatory heating is immediately turned on after the cooling and cooling is completed, or the cooling and cooling is immediately turned on after the compensatory heating is completed, or even cooling and heating are performed simultaneously.

[0073] like Figure 1 As shown, the control method includes:

[0074] S100: Obtain a startup temperature point, a shutdown temperature point, a target temperature, a compartment temperature, and an ambient temperature.

[0075] The target temperature is the temperature that is expected to be reached and maintained in the wine cabinet, which can be based on the optimal storage temperature range of wine, for example, 8-15°C.

[0076] In some embodiments, a target temperature, a first parameter, and a second parameter are preset, and a startup temperature point is calculated based on the target temperature and the first parameter, where the startup temperature point is the sum of the first parameter and the target temperature. A shutdown temperature point is calculated based on the target temperature and the second parameter, where the shutdown temperature point is the difference between the second parameter and the startup temperature point.

[0077] The first parameter is a positive or negative number, and is used to calculate the value of the startup temperature point. The first parameter is a specific temperature difference, which is added to the target temperature to determine the startup temperature point of the refrigeration or heating equipment, so that the wine cabinet can be started at the appropriate temperature, and the temperature in the wine cabinet can be adjusted towards the target temperature in time.

[0078] For example, if the first parameter is set to 2°C and the target temperature is set to 10°C, then the start-up temperature point is 12°C. When the temperature of the wine cabinet compartment reaches 12°C, the refrigeration or heating equipment will start working.

[0079] The second parameter is a positive number, which is used to calculate the positive number of the shutdown temperature point. The second parameter is used to stop the wine cabinet at the preset temperature, alleviate the situation of over-temperature adjustment, and achieve energy saving and precise temperature control.

[0080] For example, if the second parameter is set to 0.5°C, the start-up temperature point is 10°C, and the shutdown temperature point is 9.5°C. When the compartment temperature drops to 9.5°C, the refrigeration equipment will stop working.

[0081] It is understandable that the first parameter and the second parameter can be adjusted in time according to seasonal changes and changes in external conditions, and then the machine temperature point, the shutdown temperature point and other parameters can be adjusted to adapt to different environmental requirements.

[0082] The compartment temperature is the actual real-time temperature of the wine storage space inside the wine cabinet. It is obtained through real-time monitoring by the temperature sensor installed in the wine cabinet compartment, which can feedback the current temperature inside the wine cabinet. The ambient temperature is the temperature of the external environment of the wine cabinet, which can be obtained through the ambient temperature sensor installed outside the wine cabinet.

[0083] Because changes in ambient temperature will affect the internal temperature of the wine cabinet, in this embodiment, the ambient temperature is controlled separately. Under different outer ambient temperatures, accurate temperature control can be achieved, and increased power consumption can be avoided, thereby improving resource utilization.

[0084] S200: When the target temperature is lower than the ambient temperature, a first cooling rule and a first heating rule are set according to the compartment temperature, the startup temperature point and the shutdown temperature point.

[0085] When the target temperature is lower than the ambient temperature, the first cooling rule and the first heating rule are used. That is, when the wine cabinet is in a warmer environment, the cooling function is more likely to be used to maintain a low temperature, and there will also be heating rules to prevent the temperature from being too low.

[0086] In order to prevent the internal temperature of the wine cabinet from exceeding the set target temperature and thus maintain storage conditions, in some embodiments, if the compartment temperature is greater than or equal to the power-on temperature point, a first refrigeration rule is set, wherein the first refrigeration rule is to start refrigeration.

[0087] After the introduction of the first cooling rule, it can respond to temperature changes more accurately. In a high temperature environment, the temperature inside the wine cabinet will not be too high, which helps to reduce frequent starts and stops caused by temperature fluctuations, extend equipment life, and improve stability and reliability.

[0088] It is understandable that after the refrigeration is started, the compartment temperature is lowered through cyclic operation by controlling components including the compressor, condenser, evaporator, etc.

[0089] like Figure 2 As shown, in some embodiments, if the compartment temperature is greater than the shutdown temperature point and less than the startup temperature point, a first duration is obtained, if the first duration is greater than or equal to the first time, the state of the compensation heater is obtained, the state includes on and off, if the state of the compensation heater is off, a first cooling rule is set, wherein the first cooling rule is to start cooling.

[0090] Among them, the first duration is the time that the compartment temperature is greater than the shutdown temperature point and less than the startup temperature point, which is used to determine whether it is necessary to start the compensatory heating or cooling mechanism to alleviate the energy waste caused by frequent switching. The first time is a preset time threshold, which is used to determine whether it is necessary to start the compensatory heater or cooling mechanism. By setting the first time, it can be determined whether it is necessary to start the cooling mechanism when the compartment temperature fluctuates between the startup temperature point and the shutdown temperature point.

[0091] The compensating heater is used to adjust the temperature and is used in conjunction with the refrigeration system to maintain the compartment temperature within the set target range. When the compartment temperature is lower than the target temperature, the compensating heater can generate heat to increase the temperature to prevent overcooling. And in some cases, for example, when the ambient temperature is low or the refrigeration system is overworked, the compensating heater can be used to balance temperature fluctuations to prevent the quality of stored items from being affected by low temperatures.

[0092] By obtaining the status of the compensation heater, the temperature can be kept stable within the target temperature range and unnecessary energy consumption can be avoided. If the compensation heater is turned on and the compartment temperature is close to the start-up temperature point, starting the cooling mechanism will cause the wine cabinet to frequently switch between heating and cooling, resulting in energy waste and shortening the life of the equipment. By checking the status of the compensation heater, this situation can be alleviated.

[0093] The start and end of refrigeration are controlled according to the start-up temperature point and the shutdown temperature point corresponding to the target temperature, without lag or delay, to achieve precise temperature control. In addition, when the temperature in the wine cabinet is between the shutdown temperature point and the start-up temperature point, and the refrigeration is turned on according to the duration, it further ensures the timeliness of refrigeration and cooling under high ambient temperature and improves the temperature control accuracy.

[0094] In some cases, even if the compartment temperature is higher than the shutdown temperature point but not yet at the startup temperature point, if the compensating heater is already in operation and is slowly raising the temperature, the existing heating resources can be used more efficiently to reduce unnecessary energy consumption.

[0095] In some embodiments, if the compartment temperature is less than or equal to the shutdown temperature point, a first refrigeration rule is set, and at this time, the first refrigeration rule is to stop refrigeration. Through the first refrigeration rule, the refrigeration operation can be stopped when the compartment temperature reaches or is lower than the shutdown temperature point, thereby reducing the impact of low temperature on stored items and reducing unnecessary energy consumption.

[0096] like Figure 3 As shown, for the first heating rule, in some embodiments, if the compartment temperature is less than or equal to the shutdown temperature point, the second duration is obtained, and then the first temperature point is preset. If the second duration is greater than or equal to the second time, or the compartment temperature is less than or equal to the first temperature point, the first heating rule is set. At this time, the first heating rule is to start heating.

[0097] The second duration is the duration that the compartment temperature is less than or equal to the shutdown temperature point, which is used to determine whether the heating mechanism needs to be activated, especially when the compartment temperature is close to or lower than the shutdown temperature point. The second time is a preset time threshold, which is used to determine whether the heating mechanism needs to be activated.

[0098] The first temperature point is the difference between the shutdown temperature point and the third parameter. The first temperature point is used to determine whether the heating mechanism needs to be started, wherein the third parameter is a positive number.

[0099] The start temperature point of the compensatory heating is lower than the shutdown temperature point corresponding to the target temperature or there is a time delay, and the end temperature point of the compensatory heating is lower than the start temperature point corresponding to the target temperature. This can avoid the disadvantages of immediate compensatory heating after the end of cooling and cooling, or immediate cooling and cooling after the end of compensatory heating, and avoid temperature fluctuations and waste of electricity.

[0100] By setting two conditions, namely the second time and the first temperature point judgment, the temperature changes in the wine cabinet can be more comprehensively considered, alleviating the problem of untimely or overly frequent heating start-up caused by the pattern temperature point judgment, thereby improving the timeliness of temperature control and reducing energy waste.

[0101] For example, in the summer when the ambient temperature is high, if the compartment temperature is kept low for a long time and reaches below the shutdown temperature point due to frequent opening of the door to take out the wine, and the second duration is long, or the compartment temperature further drops below the first temperature point, the compensatory heating is started to prevent the wine from being damaged due to the low temperature.

[0102] In some embodiments, the second duration, the first temperature point and other parameters may also be combined with monitoring data such as ambient temperature and humidity. For example, when the ambient humidity is high, the influence of low temperature on wine may be more obvious in a high humidity environment, so the second time may be shortened to start heating in a more timely manner to protect the quality of the wine.

[0103] In some embodiments, a second temperature point is preset, the second temperature point is the difference between the power-on temperature point and a fourth parameter, the fourth parameter is a positive number, if the compartment temperature is greater than or equal to the second temperature point, a first heating rule is set, and the first heating rule is to stop heating.

[0104] The wine cabinet continuously monitors the compartment temperature. When the compartment temperature rises and reaches or exceeds the second temperature point, the first heating rule is set to stop heating, which can avoid overheating and prevent the temperature in the wine cabinet from being too high, so that the wine is always in a suitable storage temperature range, while reducing unnecessary energy consumption. For example, when the ambient temperature is high, after the wine cabinet starts heating, as the compartment temperature gradually rises, when it reaches the second temperature point, it stops heating in time to avoid damage to the wine due to excessive temperature.

[0105] When the heating stops, the working status of the ventilation equipment and humidity control equipment is adjusted according to the real-time humidity and ventilation requirements in the wine cabinet to further optimize the storage environment of the wine.

[0106] For example, when the humidity is high, after the heating stops, the humidity sensor detects that the humidity in the room is higher than the preset range, such as higher than 70%, and increases the operating power of the ventilation equipment to speed up the air circulation. The fast-flowing air can take away the excess moisture in the wine cabinet, reduce the humidity, and prevent problems such as mold growth on the wine bottle and deformation of the cork due to moisture caused by high humidity, ensuring that the storage environment of the wine is dry and hygienic.

[0107] For another example, when the humidity is low, below a preset range, such as below 60%, the humidity regulating device is controlled to start the humidification function. Through ultrasonic atomization, steam humidification, etc., an appropriate amount of water vapor is released into the wine cabinet to increase the humidity, prevent the cork from drying out and cracking, ensure the sealing of the wine, and maintain its stable quality.

[0108] S300: When the target temperature is greater than or equal to the ambient temperature, a second cooling rule and a second heating rule are set according to the compartment temperature, the startup temperature point, and the shutdown temperature point.

[0109] When the target temperature is greater than or equal to the ambient temperature, the second refrigeration rule is an auxiliary operation. When the temperature of the compartment rises due to high-temperature food, for example, when it is higher than the target temperature by a certain difference, such as 1.5°C, the refrigeration equipment is started, and the refrigeration is stopped when the temperature drops to close to the target temperature to prevent the temperature from being too high and affecting the quality of the wine.

[0110] When the compartment temperature is less than or equal to the shutdown temperature point, the heating device is started. After the temperature rises, when it reaches the startup temperature point, the heating device is stopped. When the ambient temperature is low, timely compensation heating is performed to avoid overheating.

[0111] For the second heating rule, in some embodiments, if the compartment temperature is less than or equal to the shutdown temperature point, the second heating rule is set, and the second heating rule is to start heating. By setting the second heating rule, the heating operation can be started in time when the compartment temperature reaches or is lower than the shutdown temperature point, thereby preventing energy waste caused by too low temperature and potential damage to stored items.

[0112] like Figure 4 As shown, in some embodiments, if the compartment temperature is greater than the shutdown temperature point and less than the startup temperature point, a third duration is obtained, and the third duration is the duration during which the compartment temperature is greater than the shutdown temperature point and less than the startup temperature point. If the third duration is greater than or equal to the third time, and no instruction for a cooling request is obtained, a second heating rule is set, and the second heating rule is to start heating.

[0113] The third duration is the duration when the compartment temperature is greater than the shutdown temperature point but less than the startup temperature point. The timing starts from when the compartment temperature enters this interval until the set third time threshold is reached. It is used to determine whether the heating mechanism needs to be started, especially when the compartment temperature is close to or lower than the startup temperature point and no cooling request is received.

[0114] The third time is a preset time threshold, for example, 1 hour, 2 hours, etc., which is used to determine whether the heating mechanism needs to be started. If the third duration exceeds this threshold and no instruction for cooling request is obtained, the corresponding control logic is triggered.

[0115] The cooling request instruction is sent by the user or the control system of the wine cabinet, requesting the wine cabinet to start the cooling system. For example, the user manually selects the cooling mode on the wine cabinet operation panel, and another example is automatically generated by the control system according to the preset conditions that the ambient temperature is too high and the compartment temperature exceeds a certain range. By judging the cooling request instruction, other temperature adjustment requirements that may exist in the wine cabinet can be considered to prevent the heating from being mistakenly started when cooling may be needed, thereby ensuring a suitable wine storage environment while improving energy efficiency.

[0116] If the heating start rule is determined only based on the temperature point, the actual operation of the wine cabinet may not be fully considered. By adding the time dimension, that is, comparing the third duration with the third time, the continuity of the temperature change can be considered to avoid frequent startup of the heating equipment due to short-term temperature fluctuations.

[0117] like Figure 5 As shown, for the second refrigeration rule, in some embodiments, if the compartment temperature is greater than or equal to the power-on temperature point, a fourth duration is obtained, the fourth duration is the duration during which the compartment temperature is greater than or equal to the power-on temperature point, and then a third temperature point is preset, wherein the third temperature point is the sum of the power-on temperature point and the fifth parameter, and the fifth parameter is a positive number. If the fourth duration is greater than or equal to the fourth time, or the compartment temperature is greater than or equal to the third temperature point, the second refrigeration rule is set, and the second refrigeration rule is to start refrigeration.

[0118] The fourth duration is the duration that the temperature of the wine cabinet compartment is greater than or equal to the power-on temperature point. It is obtained by the cooperation between the built-in temperature monitoring system and the timing system of the wine cabinet. When the compartment temperature reaches the power-on temperature point or above, the timing system starts timing. Once the temperature drops below the power-on temperature point, the timing stops, and the recorded duration is the fourth duration. It is used to assist in determining the duration of the over-high temperature state in the wine cabinet.

[0119] The fourth time is a preset time threshold, which is set according to the upper temperature limit requirements for wine storage and the actual operation data of the wine cabinet in different environments. It is pre-set in the control system of the wine cabinet and can be a specific time value, such as 30 minutes, 1 hour, etc. The fourth time is used to compare with the fourth duration. When the fourth duration is greater than or equal to the fourth time, the second cooling rule is triggered to prevent the temperature in the wine cabinet from being too high for a long time and causing adverse effects on the quality of the wine.

[0120] By comparing the fourth duration with the fourth time, when the compartment temperature is above the startup temperature point for a long time, the refrigeration mechanism can be started in time to prevent the temperature from rising further. A long period of high temperature may have an adverse effect on the stored items, so timely refrigeration is required.

[0121] The third temperature point is used to determine the temperature threshold for starting refrigeration, which is obtained by subtracting the fifth parameter from the power-on temperature point. The fifth parameter is set based on the optimization requirements for the refrigeration control accuracy of the wine cabinet and is pre-set in the wine cabinet control system. Even if the fourth duration does not reach the fourth time, as long as the temperature rises above the third temperature point, refrigeration will be started immediately to prevent the wine from being damaged by excessive temperature.

[0122] In some embodiments, if the compartment temperature is greater than or equal to the power-on temperature point, a second heating rule is set, and the second heating rule is to stop heating; a fourth temperature point is preset, and the fourth temperature point is the sum of the power-off temperature point and a sixth parameter, and the sixth parameter is a positive number; if the compartment temperature is less than or equal to the fourth temperature point, a second cooling rule is set, and the second cooling rule is to end cooling.

[0123] The fourth temperature point is used to determine whether the cooling mechanism needs to be terminated. The sixth parameter is a positive number. The sixth parameter can respond in advance and terminate the cooling mechanism when the temperature approaches the shutdown temperature point by adjusting the setting of the fourth temperature point.

[0124] By setting the fourth temperature point, it is possible to determine whether the refrigeration mechanism needs to be terminated when the compartment temperature fluctuates above the shutdown temperature point. This not only improves the temperature control accuracy, but also reduces the frequent start and stop caused by slight temperature fluctuations, thereby optimizing energy efficiency.

[0125] It can be understood that in this embodiment, the first parameter and the second parameter do not affect each other, and the multiple durations do not affect each other. They can all be set to 30 minutes, 1 hour, etc., and the time thresholds such as the first time and the second time and the temperature thresholds such as the first temperature point and the second temperature point can also be based on actual settings.

[0126] Based on the above-mentioned wine cabinet temperature control method, some embodiments of the present application further provide a wine cabinet, including:

[0127] Box for storing wine;

[0128] A temperature acquisition unit is used to obtain the startup temperature point, shutdown temperature point, target temperature, compartment temperature and ambient temperature;

[0129] The controller is configured as:

[0130] When the target temperature is lower than the ambient temperature, a first cooling rule and a first heating rule are set according to the compartment temperature, the startup temperature point and the shutdown temperature point;

[0131] When the target temperature is greater than or equal to the ambient temperature, a second cooling rule and a second heating rule are set according to the compartment temperature, the startup temperature point, and the shutdown temperature point.

[0132] It is understandable that in order to achieve the normal operation of the wine cabinet, in some embodiments, a refrigeration system is also included, for example, a compressor and a condenser. The compressor is used to compress and circulate the refrigerant. The condenser is a heat dissipation device used to cool the high-temperature and high-pressure refrigerant gas. The internal temperature of the wine cabinet is reduced by the circulation of the compressor refrigerant. The condenser discharges heat to the external environment to maintain the operation of the wine cabinet.

[0133] The refrigeration system also includes an evaporator, which is located inside the wine cabinet and reduces the temperature by absorbing heat so that the internal temperature reaches the set value and remains constant.

[0134] To prevent the cork from drying out and causing wine leakage or oxidation, in some embodiments, a humidification device is also provided in the wine cabinet. The humidification device is a device for increasing and maintaining the humidity inside the wine cabinet, including a humidifier and a humidity sensor. For example, the humidity range can be set to 50%-70%.

[0135] In order to improve the quality of wine and reduce odor, the wine cabinet also includes a ventilation system, which may include fans and other ventilation equipment to promote internal air circulation.

[0136] The effects of the above-mentioned device embodiment when in operation can refer to the effects of the above-mentioned method embodiment, which will not be described in detail here.

For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
