Description

Technical Field

[0001] This application relates to the field of wine cabinet technology, and in particular to an over-temperature alarm method for wine cabinets and a wine cabinet using the over-temperature alarm method. Background Technology

[0002] The taste of wines and other alcoholic beverages varies depending on storage temperature and humidity. To maintain optimal storage conditions, wines are typically stored in wine cabinets. As electrical appliances, wine cabinets use a refrigeration system to generate cool air and deliver it to the storage compartment, thus keeping the wines at a suitable temperature. However, when using a wine cabinet, malfunctions in the refrigeration system can lead to abnormal temperatures within the storage compartment. Excessively high temperatures can negatively impact the quality of the wine and even cause financial loss. Therefore, monitoring and controlling the temperature within the wine cabinet's storage compartment is crucial.

[0003] In related technologies, wine cabinets are equipped with over-temperature alarm functions. When the actual temperature of the storage compartment exceeds a certain target temperature set by the user, and the time exceeding the target temperature reaches a set time threshold, the over-temperature alarm is activated to remind the user to take appropriate action. However, when using a wine cabinet, users may leave the cabinet door open for extended periods to retrieve or store wine, or store a large quantity of room-temperature wine at once. These external factors may cause a short-term rise in the temperature of the storage compartment, resulting in false alarms.

[0004] Therefore, there is an urgent need to provide a highly accurate over-temperature alarm method to prevent false alarms caused by excessively high storage room temperature due to external factors other than abnormal cooling performance of the wine cabinet. Summary of the Invention

[0018] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:

[0019] The over-temperature alarm method in the first embodiment and the wine cabinet in the tenth embodiment of this application obtain the opening time of the wine cabinet, the temperature difference between the temperature of the wine placed in the storage room and the target temperature of the storage room during the opening time, and the increase in the amount of wine in the storage room during the opening time. Based on the opening time, the increase in the amount of wine, and the temperature difference, an invalid time is determined. The actual over-temperature duration is obtained by subtracting the invalid time from the over-temperature maintenance duration. When the actual over-temperature duration reaches or exceeds the duration threshold, an over-temperature alarm signal is output. This application considers the short-term temperature rise in the storage room caused by users opening the cabinet door for a long time or storing a large amount of room temperature wine at one time. It eliminates the influence of external factors on the storage room temperature to prevent false alarms caused by excessively high storage room temperature due to external factors other than abnormal cooling performance of the wine cabinet, thus improving the authenticity of the wine cabinet over-temperature alarm.

[0020] The over-temperature alarm method in the second embodiment of this application determines the invalid time in accordance with the actual situation of the wine cabinet, and the resulting invalid time is more reasonable, which helps to improve the authenticity of the over-temperature alarm of the wine cabinet.

[0021] The over-temperature alarm method in the third embodiment of this application further considers the influence of the ambient temperature of the wine cabinet on the temperature of the compartment. The determination of the invalid time is consistent with the actual situation of the wine cabinet, and the resulting invalid time is more reasonable, which helps to improve the authenticity of the over-temperature alarm of the wine cabinet.

[0022] The over-temperature alarm method in the fourth embodiment of this application obtains the temperature of the wine placed in the storage room by detecting the wine temperature sensor, and the obtained wine temperature is highly accurate.

[0023] The over-temperature alarm method in the sixth embodiment of this application makes the determination of regional wine temperature more reasonable and helps to obtain a more accurate temperature of wine placed in the storage room.

[0024] The over-temperature alarm method in the seventh embodiment of this application further considers the impact on the storage room temperature when the wine cabinet is only opened but no new wine is put in, thus further improving the authenticity of the wine cabinet over-temperature alarm.

Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0046] In related technologies, wine cabinets have a technical problem of false alarms due to over-temperature. The reason is that when users use wine cabinets, they may keep the cabinet door open for a long time to take out and put in wine, or store a large amount of room temperature wine in one go. These external factors may cause the temperature of the storage room to rise for a short time. The control of over-temperature alarms does not take into account the influence of these external factors, so false alarms are caused by external factors other than the abnormal cooling performance of the wine cabinet.

[0047] In view of this, the wine cabinet in this application embodiment is equipped with a weighing sensor and a wine temperature sensor. The weighing sensor is used to obtain the increase in the amount of wine in the storage room during the time the wine cabinet is opened, and the wine temperature sensor is used to obtain the temperature difference between the temperature of the wine placed in the storage room and the target temperature of the storage room during the time the door is opened. The invalid time is determined based on the opening time, the increase in the amount of wine, and the temperature difference, thereby eliminating the influence of external factors on the temperature of the storage room and preventing false alarms caused by excessively high storage room temperature due to external factors other than abnormal cooling performance of the wine cabinet. This improves the authenticity of the wine cabinet over-temperature alarm.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Figure 1 A perspective view of the exterior of a wine cabinet according to one embodiment of this application is shown. Figure 2 This application shows a schematic diagram of the concealed cabinet door of a wine cabinet according to one embodiment. Figure 3 A schematic diagram of the back of a wine cabinet according to one embodiment of this application is shown.

[0050] like Figure 1 As shown in the figure, the wine cabinet of this application embodiment includes a cabinet body 10 and a cabinet door 20.

[0051] The cabinet 10 serves as the supporting structure of the wine cabinet, and its internal structure includes a storage compartment 11 with an access opening, such as... Figure 2 As shown. Wines can be retrieved or stored in storage compartment 11 through the access port. For example, there may be one or more storage compartments 11.

[0052] The storage room 11 is equipped with wine racks 12, which are configured to hold wines. Exemplarily, there may be one or more wine racks 12. Exemplarily, when there are multiple wine racks 12, the multiple racks 12 are spaced apart vertically, dividing the storage room 11 into multiple storage areas, such as... Figure 2 As shown. Wines can be retrieved and stored in various storage areas of storage room 11 through the access ports.

[0053] The cabinet door 20 is connected to the cabinet body 10 and can move relative to the cabinet body 10. It is used to open or close the access opening of the storage compartment 11. Exemplarily, the cabinet door 20 is hinged to the cabinet body 10 and can rotate relative to the cabinet body 10. Exemplarily, there can be multiple cabinet doors 20. Each storage compartment 11 can be provided with one cabinet door 20, or multiple storage compartments 11 can be provided with one cabinet door 20. This application embodiment does not specifically limit this.

[0054] The wine cabinet in this embodiment may further include a refrigeration system installed inside the cabinet body 10. The refrigeration system includes a compressor, evaporator, condenser, capillary tube, dryer filter, connecting pipes, and a fan. The compressor, evaporator, and condenser are connected via connecting pipes, and the capillary tube and dryer filter are sequentially arranged between the evaporator and condenser.

[0055] The compressor contains refrigerant and powers the refrigeration cycle of the wine cabinet. Low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure superheated gas within the compressor and discharged into the condenser. The superheated gas then dissipates heat through the condenser, its temperature continuously decreasing until it is cooled into a high-temperature, high-pressure saturated vapor, and further cooled into a saturated liquid. The saturated liquid, after passing through a dryer filter to remove moisture and impurities, flows into a capillary tube. Through the capillary tube, it undergoes throttling and pressure reduction, transforming the refrigerant into a low-pressure, room-temperature gas. This low-pressure refrigerant gas begins to absorb heat and vaporize in the evaporator, lowering the temperature of the evaporator and its surroundings, producing low-temperature cold air, and further reducing the refrigerant's pressure. The refrigerant exiting the evaporator returns to the compressor, repeating the process to transfer heat from inside the wine cabinet to the outside air, thus achieving refrigeration in the storage compartment 11.

[0056] The fan is used to draw air into the evaporator for heat exchange, thereby producing low-temperature cold air, which is then delivered to the storage compartment of the wine cabinet to supply cold air and lower the temperature of the storage compartment. Meanwhile, the high temperature generated by the condenser is conducted into the room.

[0057] Figure 4 A block diagram illustrating a portion of the structure of a wine cabinet according to one embodiment of this application is shown.

[0058] like Figure 4 As shown, the wine cabinet in this embodiment may further include a detection device 31, which is configured to detect the open or closed state of the cabinet door 20. When the cabinet door 20 is open, the detection device 31 outputs an open signal; when the cabinet door 20 is closed, the detection device 31 outputs a closed signal.

[0059] The detection device 31 may be installed on the cabinet 10, for example, on the front side of the cabinet 10. The detection device 31 may also be installed on the cabinet door 20. This application does not specifically limit this embodiment.

[0060] like Figure 4 As shown, the wine cabinet in this embodiment may further include an alarm device 32, which is configured to trigger an alarm based on an over-temperature alarm signal. Upon receiving an over-temperature alarm signal, the alarm device 32 will sound an alarm to remind the user to take appropriate action.

[0061] For example, the alarm device 32 can be an audible alarm device, which emits an audible alarm upon receiving an over-temperature alarm signal. The alarm device 32 can also be a visual alarm device, emitting a preset visual alarm upon receiving an over-temperature alarm signal. Furthermore, the alarm device 32 can be an audible and visual alarm device, emitting an audible alarm and flashing a light upon receiving an over-temperature alarm signal. Finally, the alarm device 32 can be a display device, displaying an alarm code upon receiving an over-temperature alarm signal. This application does not specifically limit the scope of the alarm device 32.

[0062] The alarm device 32 is installed on the exterior of the wine cabinet. Exemplarily, the alarm device 32 may be installed on the cabinet body 10, for example, on the top of the cabinet body 10, or on the front side of the cabinet body 10. The alarm device 32 may also be installed on the cabinet door 20, for example, on the front side of the cabinet door 20. This application embodiment does not specifically limit this.

[0063] like Figure 2 and Figure 4 As shown, the wine cabinet in this embodiment may also include a display device 33, which is configured to display information, such as the real-time temperature, target temperature, ambient temperature, alarm information, etc. of the storage room 11.

[0064] The display device 33 can be a touch display device, which receives user input through touch operations to set information such as target temperature. The display device 33 may also have buttons, which receive user input through the buttons to set information such as target temperature.

[0065] The display device 33 is disposed on the exterior of the wine cabinet. Exemplarily, the display device 33 may be disposed on the cabinet body 10, for example, on the upper front side of the cabinet body 10. The display device 33 may also be disposed on the cabinet door 20, for example, on the front side of the cabinet door 20. This application does not specifically limit the scope of the embodiments in this regard.

[0066] For example, in some embodiments, the display device 33 may integrate alarm and detection functions, that is, it includes an alarm device 32 and a detection device 31.

[0067] like Figure 2 and Figure 4 As shown, the wine cabinet in this embodiment may further include a compartment temperature sensor 34, which is disposed within the storage compartment 11 and configured to detect the compartment temperature of the storage compartment 11. There may be one or more compartment temperature sensors 34. When there are multiple compartment temperature sensors 34, the compartment temperature can be obtained based on the temperature information detected by the multiple compartment temperature sensors 34. For example, the average temperature of the temperature values ​​detected by the multiple compartment temperature sensors 34 is calculated, and the calculated average temperature is used as the compartment temperature.

[0068] The compartment temperature sensor 34 can be located anywhere in the storage compartment 11. For example, the compartment temperature sensor 34 is located on the front side of the storage compartment 11; or, the compartment temperature sensor 34 is located on the right side of the storage compartment 11, such as... Figure 2 As shown; or, the compartment temperature sensor 34 is located on the left side of the storage compartment 11; or, the compartment temperature sensor 34 is located on the top of the storage compartment 11, etc. This application does not specifically limit this aspect.

[0069] like Figure 2 and Figure 4 As shown, the wine cabinet in this embodiment may further include a weighing sensor 35, which is disposed on the wine rack 12 and configured to detect the weight of the wines on the wine rack 12. When there are multiple wine racks 12, a weighing sensor 35 is disposed on each wine rack 12. The number of weighing sensors 35 disposed on each wine rack 12 may be one or more. When there are multiple weighing sensors 35 disposed on each wine rack 12, the weight of the wines on the wine rack 12 can be obtained based on the weight information detected by multiple weighing sensors 35. For example, the average weight detected by multiple weighing sensors 35 is calculated, and the calculated average weight is used as the weight of the wines on that wine rack 12.

[0070] like Figure 4 As shown, the wine cabinet in this embodiment may also include a wine temperature sensor 36, which is disposed in the storage chamber 11 and configured to detect the temperature of the wine on the wine rack 12.

[0071] For example, the wine temperature sensor 36 is an infrared temperature sensor.

[0072] There can be one or more wine temperature sensors 36. When there are multiple wine temperature sensors 36, the wine temperature can be obtained based on the temperature information detected by the multiple wine temperature sensors 36. For example, the average temperature of the temperature values ​​detected by the multiple wine temperature sensors 36 is calculated, and the calculated average temperature is used as the wine temperature.

[0073] For example, the wine cabinet includes multiple wine temperature sensors 36, and the highest temperature among the wine temperatures detected by the multiple wine temperature sensors 36 is used as the wine temperature placed in the storage compartment 11 within the time the door is open. By setting multiple wine temperature sensors 36, the accuracy of wine temperature detection can be improved.

[0074] For example, the wine cabinet includes multiple wine temperature sensors 36, with multiple wine temperature sensors 36 disposed between each pair of adjacent wine shelves 12. The highest temperature among the wine temperatures detected by the multiple wine temperature sensors 36 between adjacent wine shelves 12 is taken as the zone wine temperature, and the wine temperature of the storage compartment 11 can be obtained based on the wine temperatures of each zone, for example, taking the highest temperature among all zone wine temperatures as the wine temperature. By placing multiple wine temperature sensors 36 between each pair of adjacent wine shelves 12, the accuracy of wine temperature detection can be improved.

[0075] In one embodiment, three wine temperature sensors 36 are provided between every two adjacent wine racks 12, with one wine temperature sensor 36 located on the left side of the cabinet 10, one on the right side of the cabinet 10, and one in the middle of the cabinet 10. By placing the wine temperature sensors 36 at different positions between adjacent wine racks 12, the accuracy of regional wine temperature detection can be improved.

[0076] It should be noted that the wine temperature in this embodiment refers to the temperature of the wine placed in the storage room 11 within the time the door is open.

[0077] Figure 5 A partial block diagram of the wine cabinet structure of a variant of this application is shown.

[0078] like Figure 5 As shown, the wine cabinet in this embodiment may further include an ambient temperature sensor 37, which is configured to detect the ambient temperature of the wine cabinet.

[0079] There can be one or more ambient temperature sensors 37. When there are multiple ambient temperature sensors 37, the ambient temperature of the wine cabinet can be obtained based on the temperature information detected by the multiple ambient temperature sensors 37. For example, the average temperature of the temperature values ​​detected by the multiple ambient temperature sensors 37 is calculated, and the calculated average temperature is used as the ambient temperature of the wine cabinet.

[0080] An ambient temperature sensor 37 is disposed on the exterior of the wine cabinet. Exemplarily, the ambient temperature sensor 37 may be disposed on the cabinet body 10, for example, on the top of the cabinet body 10. The ambient temperature sensor 37 may also be disposed on the cabinet door 20, for example, on the front side of the cabinet door 20. This application embodiment does not specifically limit this.

[0081] like Figure 4 and Figure 5 As shown, the wine cabinet in this embodiment may further include a controller 38. The controller 38 can be communicatively connected to the detection device 31 and can receive the door opening signal and door closing signal output by the detection device 31. The controller 38 can also be communicatively connected to the compartment temperature sensor 34 and can receive the compartment temperature information detected by the compartment temperature sensor 34. The controller 38 can also be communicatively connected to the weighing sensor 35 and can receive the weight information detected by the weighing sensor 35. The controller 38 can also be communicatively connected to the wine temperature sensor 36 and can receive the wine temperature information detected by the wine temperature sensor 36. The controller 38 can also be communicatively connected to the ambient temperature sensor 37 and can receive the ambient temperature information detected by the ambient temperature sensor 37. The controller 38 can also be communicatively connected to the display device 33 and can send signals to the display device 33 to display relevant information, or receive signals sent by the display device 33 to obtain user-inputted settings information. The controller 38 can also be communicatively connected to the alarm device 32 and can send an over-temperature alarm signal to the alarm device 32 to trigger an alarm based on the over-temperature alarm signal. In addition, the controller 38 can also control the refrigeration system, such as controlling the operation of the compressor, fan, etc. of the refrigeration system, so as to control the wine cabinet to cool according to the target temperature set by the user.

[0082] Controller 38 is configured to execute an over-temperature alarm method. Figure 6 A flowchart of the over-temperature alarm method according to the first embodiment of this application is shown, as follows: Figure 6 As shown, the over-temperature alarm method includes at least steps S610 to S6110, which are described in detail below:

[0083] In step S610, the door opening signal output by the detection device is acquired. When the door opening signal output by the detection device is acquired, it indicates that the user has opened the cabinet door, and the process proceeds to step S620.

[0084] In step S620, the timer starts, and the process proceeds to step S630.

[0085] In step S630, the weight information of the wine detected by the weighing sensor is obtained, and the weight difference between the weight of the wine and the initial weight of the wine on the wine rack is calculated. Then, the process proceeds to step S640.

[0086] The initial weight of the wines on the wine rack can also be obtained by a weighing sensor. The controller records the initial weight, and the recorded initial weight can be retrieved directly in step S630 to calculate the weight difference.

[0087] Understandably, the initial weight of the wines on the wine rack is the weight of the wines on the rack detected by the weighing sensor before the user opened the cabinet door.

[0088] In step S640, it is determined whether the weight difference between the wine and the initial weight is greater than zero. If so, it is determined that the user has put the wine into the storage room, and the weight difference is determined as the wine increment.

[0089] When the difference between the weight of the wine and its initial weight is greater than zero, it means that the amount of wine on the shelf has increased, that is, the user has added wine to the storage room; conversely, when the difference between the weight of the wine and its initial weight is equal to or less than zero, it means that the amount of wine on the shelf has not increased.

[0090] When a door closing signal is received from the detection device, it indicates that the user has closed the cabinet door, and the process proceeds to step S650.

[0091] In step S650, the timing ends, and the door opening time spanning from the door opening signal to the door closing signal is obtained. Then proceed to step S660.

[0092] In step S660, the temperature of the wine placed in the storage room is obtained, and the temperature difference between the temperature of the wine placed in the storage room and the target temperature of the storage room is obtained.

[0093] The target temperature of the storage room can be set by the user through the display device. The controller records the target temperature and controls the operation of the refrigeration system based on the target temperature to keep the temperature of the storage room near the target temperature. In step S660, the controller can directly retrieve the recorded target temperature to calculate the temperature difference.

[0094] For example, the temperature of the wine placed in the storage room can be obtained by detecting it using a wine temperature sensor, which provides high accuracy. In one embodiment, in step S660, the wine temperature detected by the wine temperature sensor during the door opening time is obtained, thus obtaining the wine temperature of the wine placed in the storage room during the door opening time; the wine temperature of the wine placed in the storage room during the door opening time is subtracted from the target temperature of the storage room to obtain the temperature difference between the wine temperature of the wine placed in the storage room during the door opening time and the target temperature of the storage room.

[0095] For example, when a wine cabinet is equipped with multiple wine temperature sensors, the temperature of the wine placed in the storage room can be obtained based on the detection of multiple wine temperature sensors.

[0096] Figure 7 A detailed flowchart illustrating an embodiment of this application for obtaining the temperature of wine placed in a storage room is shown. Figure 7 As shown, the steps for obtaining the temperature of the wine placed in the storage room include steps S710 to S720, which are described in detail below:

[0097] In step S710, the wine temperature detected by multiple wine temperature sensors during the door opening time is obtained.

[0098] In step S720, the highest temperature among the wine temperatures detected by multiple wine temperature sensors is taken as the wine temperature of the wine placed in the storage room within the time limit of opening the door.

[0099] For example, when the storage room is equipped with multiple wine racks, each wine rack is equipped with a weighing sensor, and multiple wine temperature sensors are installed between two adjacent wine racks, the temperature of the wine placed in the storage room can be obtained based on the detection of multiple wine temperature sensors.

[0100] Figure 8 A detailed flowchart illustrating the process of obtaining the temperature of wine placed in a storage room is shown in a variation of this application. Figure 8 As shown, the steps for obtaining the temperature of the wine placed in the storage room include steps S810 to S850, which are described in detail below:

[0101] In step S810, it is determined whether the weighing sensor on the wine rack detected an increase in the weight of the wine during the time the door is open. If so, proceed to step S820.

[0102] In step S820, the wine temperature detected by multiple wine temperature sensors corresponding to the wine rack with increased wine weight is obtained. Then, the process proceeds to step S830.

[0103] In step S830, the highest temperature among the wine temperatures detected by multiple wine temperature sensors corresponding to the wine rack with increased wine weight is taken as the regional wine temperature.

[0104] In step S840, it is determined whether the weighing sensors on multiple wine racks have detected an increase in the weight of the wines during the door opening time. If the weighing sensors on multiple wine racks have detected an increase in the weight of the wines during the door opening time, proceed to step S850a; otherwise, proceed to step S850b.

[0105] In step S850a, the highest temperature among all the wine temperatures in all areas is taken as the wine temperature of the wine placed in the storage room within the time limit of opening the door.

[0106] In step S850b, the temperature of the wine in the area corresponding to the wine rack where the weight of the wine increases is taken as the temperature of the wine placed in the storage room during the time the door is open.

[0107] exist Figure 8 In the embodiment shown, the highest temperature among the wine temperatures detected by multiple wine temperature sensors corresponding to the wine rack with increased wine weight is taken as the regional wine temperature. The determination of the regional wine temperature is more reasonable and helps to obtain a more accurate temperature for wine placed in the storage room.

[0108] Of course, the temperature of the wine placed in the storage room can also be obtained through other means. For example, if the wine cabinet does not have a wine temperature sensor, in step S660, the ambient temperature detected by the ambient temperature sensor during the time the door is open is obtained, and this ambient temperature is used as the wine temperature of the wine placed in the storage room during that time. Since there is no need to install a wine temperature sensor, the hardware cost of the wine cabinet can be saved, and the over-temperature alarm program of the controller is also simpler to set.

[0109] In step S670, invalid time is determined based on the door opening time, the amount of wine added, and the temperature difference.

[0110] For example, step S670 specifically involves determining the invalid time based on the relationship T1 = n * Δt * M * Tc. Here, T1 represents the invalid time, Δt represents the temperature difference, M represents the increase in wine volume, Tc represents the opening time, and n is a coefficient less than 1 and greater than 0.

[0111] The longer the door is open, the more cold air escapes from the storage room, and the more hot air from the environment enters, resulting in a greater impact on the storage room temperature and a longer time required for the temperature to drop. Similarly, when wine is placed in the storage room, the wine cabinet needs time to cool down; the more wine placed in, the longer it takes for the temperature to drop. Likewise, the greater the temperature difference between the wine placed in the storage room and the target temperature of the storage room, the longer it takes for the temperature to drop and the longer the impact on the storage room temperature lasts. The invalid time is determined based on the relationship T1 = n * Δt * M * Tc. This determination of the invalid time reflects the actual situation of the wine cabinet, making the resulting invalid time more reasonable and helping to improve the accuracy of the wine cabinet's over-temperature alarm.

[0112] For example, n can be any value between 0.01 and 0.03, such as n = 0.01; or n = 0.02; or n = 0.03, etc. This application does not specifically limit this value.

[0113] The temperature difference can be expressed as: Δt=tj-ta, where tj represents the temperature of the wine placed in the storage room and ta represents the target temperature of the storage room. That is, in step S670, the invalid time is determined based on the relationship T1=n*(tj-ta)*M*Tc.

[0114] In step S680, the room temperature detected by the room temperature sensor is obtained, and it is determined whether the room temperature detected by the room temperature sensor reaches or exceeds the temperature threshold. If so, proceed to step S690.

[0115] The temperature threshold is determined based on the target temperature of the storage room. Each target temperature can correspond to a different temperature threshold, and the corresponding temperature threshold is greater than the target temperature. When the temperature of the storage room detected by the temperature sensor reaches or exceeds the temperature threshold corresponding to the set target temperature, it indicates that the temperature of the storage room is too high, and it is considered that the wine cabinet may have abnormal cooling performance. Therefore, the process proceeds to step S690 for further processing. When the temperature of the storage room detected by the temperature sensor is below the temperature threshold corresponding to the set target temperature, it indicates that the temperature of the storage room is normal, and it is considered that the cooling performance of the wine cabinet is normal. The temperature of the storage room continues to be monitored, and the process does not proceed to step S690.

[0116] When there are multiple compartment temperature sensors, for example, in step S680, it is determined whether the compartment temperature detected by the compartment temperature sensor reaches or exceeds the temperature threshold. This can be done by determining whether the compartment temperature detected by all compartment temperature sensors reaches or exceeds the temperature threshold. If so, it is considered that the wine cabinet may have abnormal cooling performance, so further processing is performed in step S690. If the compartment temperature detected by any compartment temperature sensor is below the temperature threshold, it is considered that the cooling performance of the wine cabinet is normal, and the temperature of the storage room continues to be monitored. Step S690 is not performed for the time being.

[0117] When there are multiple compartment temperature sensors, for example, in step S680, it is determined whether the compartment temperature detected by the compartment temperature sensor reaches or exceeds the temperature threshold. This can be done by determining whether the average temperature value of the compartment temperature detected by all the compartment temperature sensors reaches or exceeds the temperature threshold. If so, it is considered that the wine cabinet may have an abnormal cooling / energy performance, so the process proceeds to step S690 for further processing. If the average temperature value is below the temperature threshold, it is considered that the cooling performance of the wine cabinet is normal, and the temperature of the storage compartment continues to be monitored. Step S690 is not proceeded to at this time.

[0118] In step S690, the time during which the room temperature reaches or exceeds the temperature threshold is calculated to obtain the overheating duration, and the invalid time is subtracted from the overheating duration to obtain the actual overheating duration. Then, proceed to step S6100.

[0119] In step S6100, it is determined whether the actual over-temperature duration has reached or exceeded the duration threshold. If so, proceed to step S6110.

[0120] The duration threshold can be a reference value set based on experience. When the actual over-temperature duration reaches or exceeds the duration threshold, the cooling performance of the wine cabinet is considered abnormal and an alarm needs to be triggered immediately, so the process proceeds to step S6110. Conversely, when the actual over-temperature duration is below the duration threshold, monitoring continues.

[0121] For example, the duration threshold can be 2 hours; the duration threshold can also be 1.5 hours, 2.5 hours, etc., and this application embodiment does not specifically limit it.

[0122] In step S6110, an over-temperature alarm signal is output to the alarm device. This triggers an alarm, alerting the user to take appropriate action.

[0123] exist Figure 6 In the illustrated embodiment, the duration of the wine cabinet door being open is obtained, along with the temperature difference between the wine temperature placed in the storage room and the target temperature of the storage room during that time, and the increase in the amount of wine placed in the storage room during that time. Based on the opening duration, the increase in the amount of wine placed, and the temperature difference, an invalid time is determined. The actual over-temperature duration is obtained by subtracting the invalid time from the over-temperature maintenance duration. When the actual over-temperature duration reaches or exceeds a time threshold, an over-temperature alarm signal is output. This application considers the short-term temperature rise in the storage room caused by users opening the cabinet door for a long time or storing a large amount of room-temperature wine at once. By eliminating the influence of external factors on the storage room temperature, it prevents false alarms caused by excessively high storage room temperature due to external factors other than abnormal cooling performance of the wine cabinet, thus improving the authenticity of the wine cabinet over-temperature alarm.

[0124] See next. Figure 9 , Figure 9 A flowchart of an over-temperature alarm method according to a variation of this application is shown. Figure 9 As shown, the over-temperature alarm method includes at least steps S910 to S9120, which are described in detail below:

[0125] In step S910, the door opening signal output by the detection device is acquired. When the door opening signal output by the detection device is acquired, it indicates that the user has opened the cabinet door, and the process proceeds to step S920.

[0126] In step S920, the timer starts, and the process proceeds to step S930.

[0127] In step S930, the weight information of the wine detected by the weighing sensor is obtained, and the weight difference between the weight of the wine and the initial weight of the wine on the wine rack is calculated. Then, the process proceeds to step S940.

[0128] In step S940, it is determined whether the weight difference between the wine and the initial weight is greater than zero. If so, it is determined that the user has put the wine into the storage room, and the weight difference is determined as the wine increment.

[0129] When a door closing signal is received from the detection device, it indicates that the user has closed the cabinet door, and the process proceeds to step S950.

[0130] In step S950, the timing ends, and the door opening time spanning from the door opening signal to the door closing signal is obtained. Then proceed to step S960.

[0131] In step S960, the temperature of the wine placed in the storage room is obtained, and the temperature difference between the temperature of the wine placed in the storage room and the target temperature of the storage room is obtained.

[0132] In step S970, the ambient temperature detected by the ambient temperature sensor is acquired. Then, the process proceeds to step S980.

[0133] In step S980, invalid time is determined based on the door opening time, the amount of wine added, the temperature difference, and the ambient temperature.

[0134] For example, step S980 specifically involves determining the invalid time based on the relationship T1 = n * Δt * M * Tc * th. Here, T1 represents the invalid time, Δt represents the temperature difference, M represents the increase in wine volume, Tc represents the duration the door is open, th represents the ambient temperature of the wine cabinet, and n is a coefficient less than 1 and greater than 0.

[0135] The longer the door is open, the more cold air escapes from the storage room, and the more hot air from the environment enters, resulting in a greater impact on the storage room temperature and a longer time required for the temperature to drop. Similarly, the higher the ambient temperature, the greater the impact of hot air entering the storage room on the temperature, and the longer it takes for the temperature to drop. Likewise, when wine is placed in the storage room, the cabinet needs time to cool down; the more wine placed in, the longer it takes for the temperature to drop. Similarly, the greater the temperature difference between the wine placed in the storage room and the target temperature of the storage room, the longer it takes for the temperature to drop and the longer its influence on the storage room temperature lasts. Based on the relationship T1 = n * Δt * M * Tc * th, the invalid time is determined. This determination of the invalid time reflects the actual situation of the wine cabinet, making the resulting invalid time more reasonable and helping to improve the accuracy of the wine cabinet's over-temperature alarm.

[0136] For example, n can be any value between 0.01 and 0.03, such as n = 0.01; or n = 0.02; or n = 0.03, etc. This application does not specifically limit this value.

[0137] The temperature difference can be expressed as: Δt=tj-ta, where tj represents the temperature of the wine placed in the storage room and ta represents the target temperature of the storage room. That is, in step S980, the invalid time is determined based on the relationship T1=n*(tj-ta)*M*Tc*th.

[0138] In step S990, the room temperature detected by the room temperature sensor is obtained, and it is determined whether the room temperature detected by the room temperature sensor reaches or exceeds the temperature threshold. If so, proceed to step S9100.

[0139] In step S9100, the time during which the room temperature reaches or exceeds the temperature threshold is calculated to obtain the overheating duration, and the invalid time is subtracted from the overheating duration to obtain the actual overheating duration. Then, proceed to step S9110.

[0140] In step S9110, it is determined whether the actual over-temperature duration has reached or exceeded the duration threshold. If so, proceed to step S9120.

[0141] In step S9120, an over-temperature alarm signal is output to the alarm device. This triggers an alarm, alerting the user to take appropriate action.

[0142] exist Figure 9 In the illustrated embodiment, the duration of the wine cabinet door being open, the temperature difference between the wine temperature placed in the storage room and the target temperature of the storage room during the opening time, the increase in the amount of wine placed in the storage room during the opening time, and the ambient temperature of the wine cabinet are all obtained. Based on the opening time, the increase in the amount of wine placed, the temperature difference, and the ambient temperature, an invalid time is determined. The actual over-temperature duration is obtained by subtracting the invalid time from the over-temperature maintenance duration. When the actual over-temperature duration reaches or exceeds a time threshold, an over-temperature alarm signal is output. This application considers the short-term temperature rise in the storage room caused by users opening the cabinet door for a long time or storing a large amount of room-temperature wine at once. By eliminating the influence of external factors on the storage room temperature, it prevents false alarms caused by excessively high storage room temperature due to external factors other than abnormal cooling performance of the wine cabinet, thus improving the authenticity of the wine cabinet over-temperature alarm.

[0143] See next. Figure 10 , Figure 10 A flowchart of the over-temperature alarm method of Modification 2 of this application is shown. Figure 10 As shown, the over-temperature alarm method includes at least steps S1010 to S10120, which are described in detail below:

[0144] In step S1010, the door opening signal output by the detection device is acquired. When the door opening signal output by the detection device is acquired, it indicates that the user has opened the cabinet door, and the process proceeds to step S1020.

[0145] In step S1020, the timer starts, and the process proceeds to step S1030.

[0146] In step S1030, the weight information of the wine detected by the weighing sensor is obtained, and the weight difference between the weight of the wine and the initial weight of the wine on the wine rack is calculated. Then, the process proceeds to step S1040.

[0147] In step S1040, it is determined whether the weight difference between the wine and the initial weight is greater than zero. If so, it is determined that the user has put the wine into the storage room, and the weight difference is determined as the wine increment.

[0148] When the door closing signal is received from the detection device, it indicates that the user has closed the cabinet door, and the process proceeds to step S1050.

[0149] In step S1050, the timing ends, and the door opening time spanning from the door opening signal to the door closing signal is obtained.

[0150] If the weight difference between the wine and the initial weight is greater than zero in step S1040, proceed to step S1060b; otherwise, proceed to step S1060a.

[0151] In step S1060a, the delay duration is determined based on the door opening duration and the adjustment coefficient, and the invalid time is determined based on the door opening duration and the delay duration. Then, proceed to step S1090.

[0152] For example, in step S1060a, the delay duration is determined based on the door opening time and the adjustment coefficient. Specifically, the delay duration is determined based on the relationship Td = Tc * m. Wherein, Td represents the delay duration, Tc represents the door opening time, and m represents the adjustment coefficient, which is greater than 0.

[0153] The adjustment coefficient m can be a constant coefficient. For example, m can be any value between 10 and 30, such as m = 10, m = 20, or m = 30. This application does not specifically limit this.

[0154] Of course, the adjustment coefficient m can also be calculated based on the actual situation of the wine cabinet. For example, m is calculated based on the temperature difference between the ambient temperature of the wine cabinet and the temperature of the storage room during the time the door is open. For example, m = constant * (ambient temperature - room temperature).

[0155] For example, in step S1060a, the invalid time is determined based on the door opening time and the delay time, specifically by summing the door opening time and the delay time to obtain the invalid time.

[0156] In step S1060b, the temperature of the wine placed in the storage room is obtained, and the temperature difference between the temperature of the wine placed in the storage room and the target temperature of the storage room is obtained. Then, proceed to step S1070.

[0157] In step S1070, the ambient temperature detected by the ambient temperature sensor is acquired. Then, proceed to step S1080.

[0158] In step S1080, invalid time is determined based on the door opening time, the amount of wine added, the temperature difference, and the ambient temperature. Then, proceed to step S1090.

[0159] For example, step S1080 specifically involves determining the invalid time based on the relationship Ti = n * Δt * M * Tc * th. Where T1 represents the invalid time, Δt represents the temperature difference, M represents the increase in wine volume, Tc represents the duration the door is open, th represents the ambient temperature of the wine cabinet, and n is a coefficient less than 1 and greater than 0.

[0160] In step S1090, the room temperature detected by the room temperature sensor is obtained, and it is determined whether the room temperature detected by the room temperature sensor reaches or exceeds the temperature threshold. If so, proceed to step S10100.

[0161] In step S10100, the time during which the room temperature reaches or exceeds the temperature threshold is calculated to obtain the overheating duration, and the invalid time is subtracted from the overheating duration to obtain the actual overheating duration. Then, proceed to step S10110.

[0162] In step S10110, it is determined whether the actual over-temperature duration has reached or exceeded the duration threshold. If so, proceed to step S10120.

[0163] In step S10120, an over-temperature alarm signal is output to the alarm device. This triggers an alarm, alerting the user to take appropriate action.

[0164] exist Figure 10 In the embodiment shown, the impact on the storage room temperature when the wine cabinet is only opened but no new wine is placed inside is further considered. By setting an adjustment coefficient and determining the delay time based on the opening time and the adjustment coefficient, the invalid time for the case where the wine cabinet is only opened but no new wine is placed inside is determined based on the opening time and the delay time, which further improves the authenticity of the wine cabinet over-temperature alarm.

[0165] In one embodiment, it is also considered that when the wine cabinet is first powered on, the temperature of the storage compartment is high and it needs to be cooled for a period of time to lower the temperature of the storage compartment to below the temperature threshold corresponding to the target temperature. Therefore, a period of time after the wine cabinet is powered on is set as invalid time and no over-temperature alarm is triggered, which can improve the authenticity of the wine cabinet over-temperature alarm.

[0166] For example, when the wine cabinet is powered on, the power-on time is obtained, and a preset time is added forward from the power-on time to obtain the over-temperature calculation start time. The time interval between the power-on time and the over-temperature calculation start time is considered invalid time. The invalid time is subtracted from the over-temperature duration to obtain the actual over-temperature duration. When the actual over-temperature duration is determined to exceed the duration threshold, an over-temperature alarm signal is output to the alarm device, thereby triggering an alarm and reminding the user to take appropriate action.

[0167] For example, the preset duration can be 6 hours; the preset duration can also be 5 hours, 7 hours, etc., and this application embodiment does not specifically limit it.

[0168] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
