Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a method for temperature control of a wine cabinet and a wine cabinet. Background Technology

[0002] The ideal temperature range for long-term wine storage is 8-15℃. Home wine cabinets are designed with a target temperature range of 5-18℃ to meet the storage needs of wine.

[0003] When the ambient temperature is higher than the target temperature set for the wine cabinet, the cabinet uses its cooling system to lower the temperature. When the user places in food that is too cold, the compensating heating function is activated. When the ambient temperature is lower than the target temperature set for the wine cabinet, the cabinet primarily relies on compensating heating to raise the temperature, while using the cooling function to assist when the user places in food that is too hot.

[0004] Throughout the temperature control process, the control of cooling and compensating heating is constantly switched according to the ambient temperature and the temperature of the items inside the chamber. However, because the cooling and compensating heating frequently alternate and repeat, the start-up and switching are accompanied by energy consumption, resulting in low energy utilization efficiency.

[0053] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0054] During the storage of wine, several situations may occur, such as the ambient temperature being higher than the wine cabinet temperature, or the ambient temperature being lower than the wine cabinet temperature.

[0055] When the ambient temperature is higher than the target temperature of the wine cooler, the difference in ambient temperature varies significantly across different seasons and regions. For example, in hot summer areas, the ambient temperature may reach 35°C or even higher, while the target temperature of the wine cooler is only 18°C. In this case, the refrigeration system needs to overcome the large temperature difference to quickly lower the temperature inside the wine cooler. Furthermore, the higher the ambient temperature, the faster the heat conduction occurs on the walls and other parts of the wine cooler. The refrigeration system needs to work continuously at a high intensity to maintain the low temperature, which poses a significant challenge to the performance and stability of the refrigeration system.

[0056] Meanwhile, in high-temperature environments, the cooling system itself becomes difficult to dissipate heat. Refrigeration components such as compressors generate a lot of heat during operation. If heat cannot be dissipated in a timely and effective manner, the component temperature will rise, affecting the cooling efficiency, and may even be damaged due to overheating. The high temperature of the surrounding environment will also make the temperature of the heat dissipation medium, such as air or coolant, higher, further increasing the difficulty of heat dissipation.

[0057] When the ambient temperature is lower than the wine cabinet temperature, for example, it may reach below 0°C in a cold winter, while the wine cabinet needs to maintain the temperature above 5°C, it is necessary to accurately calculate the power of the compensating heating. The lower the ambient temperature, the greater the heating power required. However, if the heating power is too high, the temperature may rise too quickly and exceed the target temperature. If the power is too low, the temperature cannot be raised in time and it will be difficult to meet the temperature control requirements.

[0058] Furthermore, during the compensation heating process, it is important to ensure that the temperature inside the wine cabinet rises evenly to avoid localized overheating. Because the inside of a wine cabinet has different areas and structures, the position of the heating elements and the way heat is transferred will affect the temperature distribution. If the heating is uneven, some wines may be placed in an excessively high temperature environment, which will affect the quality.

[0059] During the temperature detection process inside the wine cabinet, a temperature sensor is used. The temperature sensor is a key component for controlling cooling and heating, and its accuracy affects the accuracy of temperature control. If the sensor is not accurate enough, for example, the measurement error is around ±2℃, it may cause the system to judge that cooling or heating is still needed when the actual temperature is close to the target temperature, thus 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. This may cause the cooling or heating operation to continue even when the temperature has reached near the target value. By the time the sensor detects the temperature change and issues a stop signal, the temperature has already deviated significantly from the target value, which may trigger the reverse cooling or heating operation, resulting in energy waste.

[0061] A refrigeration system takes time to reach a stable cooling effect after startup, which means there is a response speed issue. When the ambient temperature suddenly rises, the temperature inside the wine cabinet may continue to rise before the cooling capacity is sufficient to balance the heat input. At this time, the cooling power may be continuously increased. However, when the cooling capacity begins to exceed the heat input, the temperature will drop too quickly, requiring frequent adjustments to the cooling power or even compensating with heating to balance the temperature, increasing energy consumption and operating burden.

[0062] The heating system also has issues with response speed and inertia. When heating compensation is needed, after the heating element starts working, it takes time for the heat to transfer and the temperature inside the wine cabinet to rise, which may lead to overheating. Then, cooling is needed to regulate the temperature, resulting in energy waste and unstable operation.

[0063] The ambient temperature is constantly changing and the changes are uncertain. There may be large temperature fluctuations in a short period of time. For example, the temperature is high during the day and low at night. Frequent temperature changes require wine cabinets to constantly adjust their cooling and heating strategies. If these changes cannot be accurately predicted and adapted to, it will lead to frequent alternation of cooling and heating.

[0064] Other factors, such as ambient humidity, can also affect heat exchange and temperature control inside a wine cabinet. 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 inside the wine cabinet to be dry, affecting the storage conditions of the wine, and may also have an indirect impact on temperature control, making the control of refrigeration and heating more complex and increasing the difficulty of avoiding alternating operation.

[0065] In some embodiments, a high-precision temperature sensor and control system can be employed, such as a platinum resistance temperature sensor with an accuracy of ±0.1℃, which can more accurately monitor the temperature inside the chamber. Simultaneously, algorithms such as fuzzy control and PID control are used to precisely adjust the operation of the refrigeration and heating equipment based on the temperature information fed back from the sensor.

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

[0067] In other embodiments, ambient temperature and humidity monitoring sensors can be installed on the outside of the wine cabinet to acquire real-time information about the external environment. Combined with weather data or ambient temperature prediction models, this information can be used to predict trends in ambient temperature and adjust cooling or heating strategies in advance. For example, if a significant increase in the outside temperature is predicted, the internal temperature can be lowered or the operating power of the cooling system can be increased.

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

[0069] In some embodiments, the cooling and cooling start-up temperature point and the cooling and cooling end temperature point of the refrigeration system can be set separately, and the compensation heating start-up temperature point and the compensation heating end temperature point of the compensation heating system can also be set. The compensation heating start-up temperature point is equal to the cooling and cooling end temperature point, and the compensation heating end temperature point is equal to the cooling and cooling start-up temperature point. This allows for timely and lag-free response to cooling and cooling and compensation heating, and precise temperature control. However, the compensation heating starts immediately after cooling and cooling ends, and cooling and cooling also start immediately after compensation heating ends, resulting in repeated alternating operation of cooling and cooling and compensation heating, leading to significant energy waste.

[0070] In other embodiments, a wine cabinet includes a refrigeration unit and a heating unit. The temperature control method includes: acquiring 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, controlling the refrigeration unit to turn on or off, and disallowing the heating unit to turn 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, controlling the heating unit to turn on or off, and disallowing the refrigeration unit to turn on; wherein the first preset value is a positive number and the second preset value is a negative number. The advantage of this embodiment is that it solves the technical problem of simultaneous cyclic operation of refrigeration and heating in wine cabinets, resulting in energy savings. The disadvantage of this embodiment is that when the ambient temperature is high, the compensating heater is forcibly shut down; when the ambient temperature is low, the refrigeration unit is forcibly shut down. In complex user scenarios, this is not conducive to quickly achieving the target set temperature, resulting in delayed temperature control and poor temperature control accuracy.

[0071] In summary, it is impossible to precisely control cooling and compensating heating to achieve accurate temperature control. Furthermore, the alternating and repeated operation of cooling and compensating heating results in low energy efficiency.

[0072] To address the aforementioned issues, some embodiments of this application provide a wine cabinet temperature control method. This method compares the target temperature with the ambient temperature and sets different heating or cooling rules based on the comparison results. It can respond promptly and accurately to the cooling and compensating heating needs of the wine cabinet under different ambient temperatures, achieving precise temperature control. It can also solve the problem of low energy utilization efficiency caused by repeated alternation of cooling and compensating heating, i.e., the immediate activation of compensating heating after cooling or heating, or even the simultaneous operation of cooling and heating.

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

[0074] S100: Acquires power-on temperature, power-off temperature, target temperature, room temperature, and 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 for wine, for example, 8-15°C.

[0076] In some embodiments, a target temperature, a first parameter, and a second parameter are preset, and then a power-on temperature point is calculated based on the target temperature and the first parameter. The power-on temperature point is the sum of the first parameter and the target temperature. A power-off temperature point is calculated based on the target temperature and the second parameter. The power-off temperature point is the difference between the second parameter and the power-on temperature point.

[0077] The first parameter can be a positive or negative number and is used to calculate the starting temperature. It is a specific temperature difference value added to the target temperature to determine the starting temperature of the cooling or heating equipment, ensuring the wine cabinet starts at the appropriate temperature and adjusts its internal temperature towards the target temperature in a timely manner.

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

[0079] The second parameter is a positive number, used to calculate the shutdown temperature point. This second parameter ensures the wine cabinet stops operating at the preset temperature, mitigating over-adjustment and achieving energy savings and precise temperature control.

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

[0081] Understandably, the first and second parameters can be adjusted in a timely manner according to seasonal changes and changes in external conditions, thereby adjusting parameters such as the machine temperature point and the shutdown temperature point to adapt to different environmental requirements.

[0082] The compartment temperature refers to the actual, real-time temperature of the wine storage space inside the wine cabinet. This temperature is monitored in real-time by a temperature sensor installed inside the wine cabinet, providing feedback on the current temperature within the cabinet. The ambient temperature refers to the temperature of the external environment surrounding the wine cabinet, which can be obtained through an ambient temperature sensor located outside the wine cabinet.

[0083] Since changes in ambient temperature can affect the internal temperature of a wine cabinet, this embodiment uses separate control based on ambient temperature. This allows for precise temperature control under different ambient temperatures, while also preventing increased power consumption and improving resource utilization.

[0084] S200: When the target temperature is lower than the ambient temperature, the first cooling rule and the first heating rule are set by the room temperature, the start-up 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. In other words, when the wine cabinet is in a warmer environment, it tends to use the cooling function to maintain a low temperature, while the heating rule will also be in place to prevent the temperature from getting too low.

[0086] To ensure that the internal temperature of the wine cabinet does not exceed the set target temperature and thus maintain storage conditions, in some embodiments, if the compartment temperature is greater than or equal to the start-up temperature, a first cooling rule is set, wherein the first cooling rule is to start cooling.

[0087] After the introduction of the first cooling rule, it can respond to temperature changes more accurately. In high-temperature environments, the internal temperature of the wine cabinet will not be too high, which helps to reduce frequent start-ups and shutdowns caused by temperature fluctuations, extend the equipment life, and improve stability and reliability.

[0088] It is understandable that after the cooling system is started, the room temperature is reduced by controlling components such as the compressor, condenser, and evaporator to work in a cycle.

[0089] like Figure 2 As shown, in some embodiments, if the room temperature is greater than the shutdown temperature point but 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, including whether it is on or 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] The first duration is the time during which the room temperature is higher than the shutdown temperature but lower than the startup temperature. This is used to determine whether to activate the compensating heating or cooling mechanism to mitigate energy waste caused by frequent switching. The first time is a preset time threshold used to determine whether to activate the compensating heater or cooling mechanism. By setting the first time, it is possible to determine whether to activate the cooling mechanism when the room temperature fluctuates between the startup and shutdown temperatures.

[0091] Compensating heaters are used to regulate temperature in conjunction with refrigeration systems to maintain the compartment temperature within a set target range. When the compartment temperature falls below the target temperature, the compensating heater generates heat to raise the temperature and prevent overcooling. Furthermore, in certain situations, such as when the ambient temperature is low or the refrigeration system is overworking, compensating heaters can balance temperature fluctuations, preventing excessively low temperatures from affecting the quality of stored items.

[0092] Monitoring the status of the compensating heater ensures the temperature remains stable within the target range and avoids unnecessary energy consumption. If the compensating heater is on and the compartment temperature is close to the start-up temperature, activating the cooling mechanism will cause the wine cabinet to frequently switch between heating and cooling, resulting in energy waste and shortening the equipment's lifespan. Checking the status of the compensating heater can mitigate this situation.

[0093] The cooling system responds and controls the start and stop of cooling based on the start and stop temperatures corresponding to the target temperature, without lag or delay, achieving precise temperature control. In addition, when the temperature inside the wine cabinet is between the stop and start temperatures, the cooling system is activated based on the duration, further ensuring timely cooling and improving temperature control accuracy under higher ambient temperatures.

[0094] In some cases, even if the room temperature is higher than the shutdown temperature but not the startup temperature, if the compensation heater is already working and slowly increasing the temperature, the existing heating resources can be utilized more efficiently, reducing unnecessary energy consumption.

[0095] In some embodiments, if the compartment temperature is less than or equal to the shutdown temperature, a first cooling rule is set, in which case the first cooling rule is to stop cooling. This first cooling rule allows cooling to stop when the compartment temperature reaches or falls below the shutdown temperature, thereby reducing the impact of excessively low temperatures on stored items and minimizing unnecessary energy consumption.

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

[0097] The second duration is the time during which the chamber temperature remains below or equal to the shutdown temperature. This is used to determine whether the heating mechanism needs to be activated, especially when the chamber temperature is close to or below the shutdown temperature. The second time is a preset time threshold 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 activated. The third parameter is a positive number.

[0099] The compensation heating start temperature is lower than the target temperature corresponding to the shutdown temperature or there is a time delay. The compensation heating end temperature is lower than the target temperature corresponding to the start temperature. This avoids the disadvantages of immediately compensating for heating after cooling or immediately cooling after compensation heating, thus avoiding temperature fluctuations and energy waste.

[0100] By setting two conditions—a second time and a first temperature point—the temperature changes inside the wine cabinet can be considered more comprehensively, alleviating the problem of untimely or excessively frequent heating starts caused by temperature point judgments. This improves the timeliness of temperature control and reduces energy waste.

[0101] For example, in summer when the ambient temperature is high, if the temperature in the storage room remains below the shutdown temperature for an extended period due to frequent opening of the door to retrieve wine, and this condition persists for a long time, or if the temperature in the storage room further drops below the first temperature point, the compensatory heating will be activated to prevent the wine from being damaged by the excessively low temperature.

[0102] In some embodiments, parameters such as the second duration and the first temperature point can be combined with monitoring data such as ambient temperature and humidity. For example, when the ambient humidity is high, the impact of low temperature on wine may be more pronounced in high humidity environments. Shortening the second duration allows for more timely initiation of heating, thus protecting the quality of the wine.

[0103] In some embodiments, a second temperature point is preset, which is the difference between the start-up temperature point and the fourth parameter, where the fourth parameter is a positive number. If the room temperature is greater than or equal to the second temperature point, a first heating rule is set, which is to stop heating.

[0104] The wine cabinet continuously monitors the compartment temperature. When the compartment temperature rises and reaches or exceeds a second temperature point, the first heating rule is set to stop heating. This prevents overheating and ensures the wine remains within the appropriate storage temperature range, while also reducing unnecessary energy consumption. For example, when the ambient temperature is high, after the wine cabinet starts heating, it will gradually rise and then stop heating promptly when the second temperature point is reached, preventing damage to the wine from excessive heat.

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

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

[0107] For example, when the humidity is low, below a preset range, such as below 60%, the humidity control device will activate the humidification function. Through ultrasonic atomization, steam humidification, or other methods, an appropriate amount of water vapor is released into the wine cabinet to increase humidity, preventing the cork from drying out and cracking, ensuring the wine's airtightness, and maintaining its quality stability.

[0108] S300: When the target temperature is greater than or equal to the ambient temperature, the second cooling rule and the second heating rule are set by the room temperature, the start-up 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 in the compartment rises due to the placement of hot food or other reasons, and exceeds the target temperature by a certain difference, such as 1.5°C, the refrigeration equipment is activated, and the refrigeration is stopped when the temperature drops to near the target temperature to prevent the temperature from being too high and affecting the quality of the wine.

[0110] When the room temperature is less than or equal to the shutdown temperature, the heating equipment is started. After the temperature rises, the heating equipment is stopped when the startup temperature is reached. When the ambient temperature is low, timely heating is provided to compensate for the temperature drop, while avoiding overheating.

[0111] In some embodiments, for the second heating rule, if the compartment temperature is less than or equal to the shutdown temperature, a second heating rule is set to initiate heating. By setting the second heating rule, heating can be initiated promptly when the compartment temperature reaches or falls below the shutdown temperature, thereby preventing energy waste and potential damage to stored items due to excessively low temperatures.

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

[0113] The third duration is the duration during which the room temperature is greater than the shutdown temperature but less than the startup temperature. The timer starts when the room temperature enters this range and continues until the set third time threshold is reached. This is used to determine whether the heating mechanism needs to be activated, especially when the room temperature is close to or lower than the startup temperature and no cooling request has been received.

[0114] The third time is a preset time threshold, such as 1 hour or 2 hours, used to determine whether the heating mechanism needs to be activated. If the third duration exceeds this threshold and no cooling request instruction is received, the corresponding control logic is triggered.

[0115] A cooling request command is issued by the user or the wine cabinet's control system, requesting the wine cabinet to activate its cooling system. For example, the user may manually select a cooling mode on the wine cabinet's control panel, or the control system may automatically generate one based on preset conditions such as excessively high ambient temperature or the compartment temperature exceeding a certain range. By analyzing cooling request commands, other potential temperature adjustment needs of the wine cabinet can be considered, preventing the erroneous activation of heating when cooling is required. This ensures a suitable wine storage environment while improving energy efficiency.

[0116] If the heating start rule is determined solely based on the temperature point, it may not fully consider the actual operating conditions of the wine cabinet. By adding a time dimension, namely comparing the third duration with the third time, the continuity of temperature changes can be taken into account, thus avoiding frequent activation of the heating equipment due to short-term temperature fluctuations.

[0117] like Figure 5 As shown, for the second cooling rule, in some embodiments, if the room temperature is greater than or equal to the start-up temperature point, a fourth duration is obtained, which is the duration for which the room temperature is greater than or equal to the start-up temperature point. Then, a third temperature point is preset, where the third temperature point is the sum of the start-up temperature point and a 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 room temperature is greater than or equal to the third temperature point, the second cooling rule is set, and the second cooling rule is to start cooling.

[0118] The fourth duration is the length of time the wine cabinet compartment temperature remains above or equal to the start-up temperature. This is obtained through the combined operation of the wine cabinet's built-in temperature monitoring and timing systems. The timing system starts when the compartment temperature reaches or exceeds the start-up temperature and stops when the temperature drops below it; the recorded duration is the fourth duration. This is used to help determine the persistence of excessively high temperatures within the wine cabinet.

[0119] The fourth time is a preset time threshold, set based on the upper temperature limit requirements for wine storage and combined with actual operating data of the wine cabinet under different environments. It is pre-set in the wine cabinet's control system and can be a specific time value, such as 30 minutes or 1 hour. 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 wine cabinet from being excessively hot for an extended period, which could adversely affect the quality of the wine.

[0120] By comparing the fourth duration with the fourth time, the cooling mechanism can be activated in time when the temperature in the compartment remains above the start-up temperature for an extended period, preventing the temperature from rising further. Prolonged high temperatures may have an adverse effect on stored items, therefore, timely cooling is necessary.

[0121] The third temperature point is the threshold temperature used to determine whether to activate cooling. It is obtained by subtracting the fifth parameter from the start-up temperature. The fifth parameter is set in advance in the wine cabinet control system based on the optimization requirements for the wine cabinet's cooling control precision. Even if the fourth duration has not been reached, as long as the temperature rises above the third temperature point, cooling will be activated immediately to prevent excessively high temperatures from damaging the wine.

[0122] In some embodiments, if the room temperature is greater than or equal to the start-up temperature, a second heating rule is set, which is to stop heating; a fourth temperature point is preset, which is the sum of the shutdown temperature and a sixth parameter, wherein the sixth parameter is a positive number; if the room temperature is less than or equal to the fourth temperature point, a second cooling rule is set, which 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. By adjusting the setting of the fourth temperature point, the sixth parameter can respond in advance and terminate the cooling mechanism when the temperature is close to the shutdown temperature point.

[0124] By setting a fourth temperature point, it is possible to determine whether the cooling mechanism needs to be stopped when the room temperature fluctuates around the shutdown temperature. This not only improves temperature control accuracy but also reduces frequent start-stop cycles caused by minor temperature fluctuations, thereby optimizing energy efficiency.

[0125] It is 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 either. They can all be set to 30 minutes, 1 hour, etc. Furthermore, the time thresholds such as the first time and the second time, as well as the temperature thresholds such as the first temperature point and the second temperature point, can also be set based on actual conditions.

[0126] Based on the above-described wine cabinet temperature control method, some embodiments of this application also provide a wine cabinet, including:

[0127] The container is used to store wine;

[0128] The temperature acquisition unit is used to acquire the power-on temperature point, power-off temperature point, target temperature, room temperature, and ambient temperature.

[0129] The controller is configured as follows:

[0130] When the target temperature is lower than the ambient temperature, a first cooling rule and a first heating rule are set based on the room temperature, the start-up 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 based on the room temperature, the start-up temperature point, and the shutdown temperature point.

[0132] Understandably, to ensure the normal operation of a wine cabinet, some embodiments also include a refrigeration system, such as a compressor and a condenser. The compressor compresses and circulates the refrigerant. The condenser is a heat dissipation device used to cool the high-temperature, high-pressure refrigerant gas. Through the circulation of the refrigerant by the compressor, the internal temperature of the wine cabinet is reduced. The condenser dissipates heat to the external environment, maintaining the operation of the wine cabinet.

[0133] The refrigeration system also includes an evaporator, which is located inside the wine cabinet. The evaporator absorbs heat to lower the temperature, bringing the internal temperature to a set value and maintaining it at a constant level.

[0134] To prevent the cork from drying out and causing wine leakage or oxidation, in some embodiments, a humidification device is also provided inside the wine cabinet. The humidification device is a device used to increase and maintain 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] To improve wine quality and reduce off-odors, wine cabinets also include ventilation systems, which may include fans and other ventilation equipment to promote internal air circulation.
