Description

Technical Field

[0001] This invention relates to the field of beverage storage, and in particular to a wine cabinet with switchable temperature zones and a control method thereof. Background Technology

[0002] In existing technology, once the temperature zones of a wine cabinet are set, they cannot be changed. When a user wants to change the type of wine stored (e.g., initially storing sparkling wine at 5-12℃ in the lower temperature zone, and later needing to store red wine at 12-18℃, and the upper temperature zone for sparkling wine), because the temperature zones cannot be switched, it is impossible to adapt to the new needs by adjusting the temperature. Instead, the user must manually remove the bottles of sparkling wine from the lower temperature zone one by one, then place the bottles of red wine to be stored into the lower temperature zone one by one, and then place the removed sparkling wines into the upper temperature zone one by one. The whole process is cumbersome and time-consuming, especially when storing a large number of wines, the operational burden increases significantly. In addition, frequent opening of the door to take out and put in wines will cause a large amount of cold air to be lost from the inside of the wine cabinet, which will disrupt the original stable temperature environment. This may not only affect the quality of the wines that have not been moved, but also increase the operating load of the refrigeration components and consume additional energy. Summary of the Invention

[0003] Therefore, it is necessary to provide a wine cabinet with switchable temperature zones and a control method to address the issue that the temperature zones of wine cabinets are fixed and cannot be changed.

[0004] A wine cabinet with switchable temperature zones includes: a cabinet assembly having a storage space and a cooling space; a cooling assembly disposed on the cabinet assembly, with a portion of the cooling assembly located in the cooling space and the remainder located in the storage space; a fan disposed on the cabinet assembly and located in the cooling space, the fan being adjacent to the cooling assembly; and a partition disposed on the cabinet assembly and located in the storage space, the partition dividing the storage space into a first temperature control zone and a second temperature control zone. The partition plate has a circulation space; the fan can rotate in a first direction or a second direction. When the fan rotates in the first direction, the cooling space, the first temperature control zone, the circulation space, the second temperature control zone, and the cooling space are sequentially and cyclically connected. The temperature of the first temperature control zone is less than or equal to the temperature of the second temperature control zone. When the fan rotates in the second direction, the cooling space, the second temperature control zone, the circulation space, the first temperature control zone, and the cooling space are sequentially and cyclically connected. The temperature of the first temperature control zone is greater than or equal to the temperature of the second temperature control zone. The first direction and the second direction are opposite.

[0005] The aforementioned design discloses a wine cabinet with switchable temperature zones. Existing wide-range temperature-controlled dual-zone wine cabinets require two independent refrigeration systems, while non-wide-range temperature-controlled solutions require at least two fan motors, both of which suffer from high costs and energy consumption. This wine cabinet, however, relies on only one refrigeration unit and a single fan, achieving temperature zone switching by changing the fan's direction. It eliminates the need for additional evaporators and motor loads, significantly reducing equipment manufacturing costs and minimizing energy consumption from motor operation. Furthermore, existing solutions, due to their multi-component layout, occupy a large amount of internal space, limiting the actual wine storage capacity. This wine cabinet simplifies the internal structure, eliminating unnecessary evaporators and motors, and using only a central partition for space division. The partition's flow space design does not affect the overall storage layout, maximizing the utilization of the cabinet's component space. Furthermore, this wine cabinet overcomes the limitations of existing non-wide-range temperature control solutions with fixed temperature zone functions. Existing solutions, once designed, cannot change the temperature range of the two zones, failing to meet users' flexible wine storage needs. For example, it's impossible to change the original 5-12℃ first temperature control zone to 12-18℃ for storing red wine, while simultaneously storing sparkling wine in the second temperature zone. This wine cabinet, however, controls the airflow circulation direction by rotating a fan in either the first or second direction. When the fan rotates in the first direction, the cooling space, the first temperature control zone, the circulation space, the second temperature control zone, and the cooling space are sequentially and continuously connected, ensuring that the temperature in the first temperature control zone is less than or equal to that in the second temperature control zone. Temperature: When the fan rotates in the second direction, the cooling space, the second temperature control zone, the circulation space, the first temperature control zone, and the cooling space are sequentially and circulated. The temperature of the first temperature control zone is greater than or equal to the temperature of the second temperature control zone. This allows for flexible switching between the temperature ranges of the first and second temperature control zones. It can meet the basic requirement of 5-12℃ in one temperature zone and 12-18℃ in another temperature zone. It can also adjust the temperature range of the two temperature zones at any time according to the changes in wine storage. It perfectly adapts to the storage temperature requirements of different types of wine such as red wine, white wine, and sparkling wine, truly realizing multi-purpose use of one cabinet and greatly improving the functional flexibility of the equipment and the user experience.

[0006] In one embodiment, the refrigeration assembly includes an evaporator and a compressor. The evaporator is mounted on the housing assembly and located within the refrigeration space. The fan is disposed adjacent to the evaporator, and the compressor is mounted on the housing assembly and located within the first temperature control zone. By placing the evaporator near the fan in the refrigeration space, the fan can more efficiently deliver cooling capacity to each temperature zone, reducing cooling capacity loss and improving refrigeration efficiency. The compressor is placed in the first temperature control zone, eliminating the need for additional refrigeration space or other areas, thus optimizing the internal space layout. Combined with the reasonable partitioning of the central partition, this allows for higher utilization of the storage space. Simultaneously, this layout clearly defines the functions of each component of the refrigeration assembly. In conjunction with the fan-driven temperature control mechanism, it enables more precise temperature adjustment of the first and second temperature control zones, achieving both low energy consumption and low cost advantages for a single system while enhancing temperature control stability.

[0007] In one embodiment, the evaporator includes an evaporator body and a defrost sensor. The evaporator body is mounted on the housing assembly and located within the refrigeration space. The defrost sensor is mounted on the evaporator body and located within the refrigeration space, with the defrost sensor positioned on the side of the evaporator body closest to the fan. The evaporator body, acting as the core for generating cooling capacity, is stably positioned within the refrigeration space to ensure a continuous supply of cooling. The defrost sensor's proximity to the fan allows for more sensitive detection of frost formation on the evaporator body surface. Since airflow is active near the fan, frost formation can easily disrupt airflow circulation. The defrost sensor can detect frost thickness in advance, preventing frost accumulation from clogging the air ducts. This design triggers the defrost mechanism promptly, preventing obstruction of cooling capacity delivery. It maintains the fan's efficient cooling advantage while preventing the evaporator body from reducing cooling efficiency due to frost formation, ensuring temperature stability in both the first and second temperature control zones.

[0008] In one embodiment, the housing assembly includes a main housing, a door, and a refrigeration cover. The door is mounted on the main housing and can rotate relative to it. Rotating the door relative to the main housing allows for opening or closing of the accommodating space. The refrigeration cover is mounted on the main housing and cooperates with it to form the refrigeration space. The refrigeration assembly is mounted on the main housing, the fan is mounted on the main housing, and the partition is mounted on the main housing and / or the refrigeration cover. By using the main housing as the core load-bearing structure, a stable installation foundation is provided for the refrigeration assembly and fan. Simultaneously, the rotational cooperation with the door allows for flexible opening or closing of the accommodating space, facilitating user access to wine and minimizing cold loss within the accommodating space, ensuring temperature control stability. The refrigeration cover, in conjunction with the main housing, forms an independent refrigeration space, providing a sealed and suitable working environment for the evaporator, preventing cold leakage. Combined with precise defrosting control by a defrosting sensor, this further improves refrigeration efficiency. The partition plate, installed on the main housing and / or the cooling cover, precisely divides the space into a first temperature control zone and a second temperature control zone. This partition design is the core foundation for achieving independent temperature control in both zones. It effectively blocks the free flow of air between the two zones, preventing the disorderly diffusion of cold energy between zones and temperature cross-contamination. It also provides structural support for the subsequent fan to adjust the airflow circulation direction by reversing the direction of rotation and achieve temperature difference switching between the two zones.

[0009] In one embodiment, the cooling space includes a cooling cavity, a first air outlet, and a second air outlet. A portion of the cooling component is located in the cooling cavity. The fan is located in the cooling cavity and is positioned opposite to the second air outlet. When the fan rotates in the first direction, the cooling cavity, the first air outlet, the first temperature control zone, the circulation space, the second temperature control zone, the second air outlet, and the cooling cavity are cyclically connected. When the fan rotates in the second direction, the cooling cavity, the second air outlet, the second temperature control zone, the circulation space, the first temperature control zone, the first air outlet, and the cooling cavity are cyclically connected. By utilizing the cooling chamber, an independent and enclosed working environment is provided for the cooling components and the fan, reducing the loss of cold energy within the cooling space and ensuring centralized generation and delivery of cold energy. The first and second air vents serve as precise channels for airflow into and out of the cooling chamber. Combined with fan rotation control, a clear circulation path is constructed. When the fan rotates in the first direction, cold energy enters the first temperature control zone through the first air vent, then flows through the circulation space and the second temperature control zone before returning through the second air vent, ensuring a lower temperature in the first temperature control zone. When rotating in the second direction, the circulation reverses, resulting in a lower temperature in the second temperature control zone. This structured airflow path design avoids disordered diffusion of cold energy within the storage space, making the temperature difference between the two temperature control zones more stable. Combined with the temperature zone separation function of the partition, it not only maintains the low energy consumption advantage of a single system but also makes the switching between dual temperature zones more efficient and the temperature control more precise. This reliably meets the specific storage temperature requirements of different types of wine, such as red wine and sparkling wine, significantly improving wine storage performance and user experience.

[0010] In one embodiment, the fan is a centrifugal fan. By setting the fan as a centrifugal fan, a stronger and more stable airflow can be formed in the cooling chamber. Combined with the layout opposite to the second air outlet, the cooling capacity generated by the cooling components can be efficiently delivered to the first or second air outlet, reducing the attenuation of the airflow in the circulation path and ensuring that the cooling capacity quickly and evenly covers the first and second temperature control zones.

[0011] In one embodiment, the fan is an axial flow fan. By setting the fan as an axial flow fan, it has the advantages of large airflow, moderate air delivery distance and low operating noise. Combined with its layout opposite the second air outlet, it can form a stable and wide-coverage airflow in the cooling cavity, efficiently delivering the cold energy generated by the cooling components to the first or second air outlet, avoiding local cold energy accumulation, and ensuring temperature uniformity between the first and second temperature control zones.

[0012] In one embodiment, the door is a glass door. By making the door a glass door, the user can clearly observe the storage status of the wine in the first and second temperature control zones within the storage space without opening the door, avoiding the loss of cold air due to frequent door opening. This ensures the temperature stability of the dual temperature zones and reduces the additional energy consumption of the refrigeration components, which aligns with the low energy consumption advantage of a single system.

[0013] In one embodiment, the door is a foamed door. By using a foamed door, heat exchange between the storage space and the outside environment can be significantly reduced, preventing external high or low temperatures from interfering with the temperatures of the first and second temperature control zones. This effectively maintains a constant temperature in both zones, providing a more stable storage environment for wines such as red wine and sparkling wine. Simultaneously, the excellent insulation reduces the operating load on the refrigeration components, decreasing the start-stop frequency of the compressor and fan, further saving energy consumption while maintaining the low energy consumption advantage of a single system.

[0014] In one embodiment, the circulation space includes a first air inlet, a circulation channel, and a second air inlet. When the fan rotates in the first direction, the cooling space, the first temperature control zone, the first air inlet, the circulation channel, the second air inlet, the second temperature control zone, and the cooling space are sequentially and cyclically connected. When the fan rotates in the second direction, the cooling space, the second temperature control zone, the second air inlet, the circulation channel, the first air inlet, the first temperature control zone, and the cooling space are sequentially and cyclically connected. By refining the circulation space into a first air inlet, a circulation channel, and a second air inlet, the airflow within the accommodating space becomes more directional. When the fan rotates in the first direction, the cooling energy enters the first temperature control zone from the cooling space. It then precisely enters the circulation channel through the first air vent, flows smoothly into the second temperature control zone through the second air vent, and finally returns to the cooling space. This avoids temperature disturbances caused by disordered airflow diffusion, ensuring that the temperature in the first temperature control zone is lower than that in the second temperature control zone. When the fan rotates in the second direction, the airflow reverses, passing through the second air vent, the circulation channel, and the first air vent, consistently achieving an even lower temperature in the second temperature control zone. Simultaneously, the circulation channel reduces cooling energy loss during zone transitions. Combined with the partition's separation function and the cooling supply from the refrigeration components, this maintains the low energy consumption and low cost advantages of a single system while ensuring a more stable temperature difference and more precise temperature regulation between the two temperature control zones. Furthermore, the first and second air vents can be designed with structures such as grilles or perforated panels to improve airflow efficiency.

[0015] In one embodiment, a sensor assembly is further included, comprising a first sensor and a second sensor. The first sensor is disposed on the housing assembly and located on its side wall, within the first temperature control zone. The second sensor is disposed on the housing assembly and located on its side wall, within the second temperature control zone. By disposing the first and second sensors on the side wall of the housing assembly and correspondingly located in the first and second temperature control zones, respectively, the two sensors can independently and in real-time collect temperature data for their respective temperature control zones. This avoids misjudgments due to regional temperature differences caused by single-sensor temperature measurement. When the temperature in either the first or second temperature control zone deviates from the set value, it can be quickly fed back to the control system, allowing for timely adjustment of the fan direction and the operating status of the refrigeration components.

[0016] The second aspect of this application discloses a control method for a wine cabinet with switchable temperature zones. The control method for the wine cabinet with switchable temperature zones includes the following steps: S1. Set the temperature of the first temperature control zone T1 and the temperature of the second temperature control zone T2, and calculate the set temperature difference Δt between the first temperature control zone and the second temperature control zone. Δt = T2 - T1. The wine cabinet with switchable temperature zones has at least a first working mode and a second working mode. When the wine cabinet with switchable temperature zones is in the first working mode, Δt ≥ 0℃. When the wine cabinet with switchable temperature zones is in the second working mode, Δt ≤ 0℃. S2. Start the cooling unit to circulate the cold energy released by the cooling unit within the wine cabinet with switchable temperature zones. According to the working mode set by the wine cabinet with switchable temperature zones, start the fan and adjust the rotation direction of the fan. When the wine cabinet with switchable temperature zones is set to the first working mode, set the rotation direction of the fan to the first direction. When the wine cabinet with switchable temperature zones is set to the second working mode, set the rotation direction of the fan to the second direction. S3. Based on the working mode of the wine cabinet with switchable temperature zones, set the preset temperature difference, compare the magnitude of the set temperature difference Δt with the preset temperature difference, and adjust the rotation speed of the fan.

[0017] The second aspect disclosed above discloses a control method for a wine cabinet with switchable temperature zones. First, by setting T1 and T2 and calculating Δt, combined with the division of Δt ≥ 0℃ or ≤ 0℃ for the first and second working modes, the method accurately matches the dual-temperature zone switching requirements of the wine cabinet, solving the problem of fixed temperature zone functions in existing wine cabinets. Users can flexibly define the temperature relationship between the upper and lower temperature zones according to the storage needs of different types of wine, such as red wine and sparkling wine, resulting in stronger adaptability. Second, the fan direction is adjusted according to the working mode, coordinating with the air outlet layout of the wine cabinet's cooling space and the airflow structure of the circulation space to ensure that the cold air circulates along a preset path, avoiding disorderly loss of cold air, and improving cooling efficiency in conjunction with the efficient cooling components. Finally, a preset temperature difference is set according to the mode, and the fan speed is adjusted in stages by comparing Δt with the preset temperature difference. This avoids the problem of low temperature difference control accuracy caused by single-speed operation, and can quickly uniformly heat the temperature at a higher speed when the temperature difference is small, and accurately control the temperature at a lower speed when the temperature difference is large, reducing the ineffective energy consumption of the fan and continuing the low energy consumption advantage of a single system.

[0018] In one embodiment, S3 includes the following steps: S31. When the wine cabinet with switchable temperature zones is in the first working mode, a first preset temperature difference △t1 and a second preset temperature difference △t2 are set. The magnitude relationship between the set temperature difference △t and the first preset temperature difference △t1 and the second preset temperature difference △t2 is compared, and the rotation speed of the fan is adjusted, wherein △t1>△t2>℃. S32. When the wine cabinet with switchable temperature zones is in the second working mode, set the third preset temperature difference △t3 and the fourth preset temperature difference △t4, compare the magnitude relationship between the set temperature difference △t and the third preset temperature difference △t3 and the fourth preset temperature difference △t4, and adjust the rotation speed of the fan, wherein 0℃>△t3>△t4.

[0019] By classifying △t1 and △t2 in the first working mode △t≥0℃, the fan speed can be flexibly matched according to the actual temperature difference requirements: when △t is large (such as approaching the maximum temperature difference limit of the wine cabinet), the speed is adjusted to a low speed according to △t1 to accurately control the distribution of cooling capacity and maintain a stable temperature difference; when △t is small (such as when the first and second temperature control zones need to be close), the speed is switched to a higher speed according to △t2 to quickly achieve uniform temperature and avoid temperature control lag or energy waste caused by a single-level preset temperature difference. In the second working mode △t≤0℃, the classification of △t3 and △t4 is similar, adapting to the temperature difference control requirements under reverse airflow circulation, ensuring that the fan speed adjustment is deeply coordinated with the cooling capacity circulation path and the airflow efficiency of the middle partition space. This refined setting not only realizes the core advantage of adjusting the speed according to the temperature difference, but also makes the speed adjustment more in line with the needs of different temperature zones through patterned and differentiated presets. Combined with the efficient cooling of the refrigeration components and the real-time temperature measurement of the sensor components, it further reduces ineffective energy consumption, improves the stability of dual-temperature zone temperature control, better meets the temperature accuracy requirements of diverse wine storage such as red wine, white wine, and sparkling wine, and enhances the user's professional wine storage experience.

[0020] In one embodiment, S31 includes the following steps: S311. When Δt < Δt2, adjust the fan speed to reach the first rotational speed P1. S312. When △t2≤△t<△t1, adjust the rotation speed of the fan to reach the second rotation speed P2. S313. When △t1≤△t, adjust the rotation speed of the fan to reach the third rotation speed P3, where P1>P2>P3.

[0021] The above steps enable the wine cabinet with switchable temperature zones to adjust the temperature difference between the temperature control zones in the first operating mode. When Δt < Δt2 (when the temperature difference is small, such as when the second temperature control zone is 12℃ and the first temperature control zone is 12℃), the control fan can operate at a high speed P1 of 1800RPM, which can quickly circulate the cold energy generated by the evaporator through the cooling space, the first temperature control zone, the circulation space, the second temperature control zone, and the cooling space, reducing the stagnation of cold energy in the circulation path and achieving rapid and uniform temperature in the two temperature control zones, avoiding the problem of slow temperature equalization caused by insufficient speed; when Δt2 ≤ Δt < Δt1, the temperature difference is moderate, such as when the second temperature control zone is 12℃. With the temperature control zone at 14℃ and the first temperature control zone at 10℃, the fan can be switched to a speed of 1500RPM (P2). While ensuring effective delivery of cooling capacity, the fan can adjust the cooling capacity distribution ratio by appropriately reducing the speed, preventing the temperature difference from further shrinking or widening, and maintaining the temperature stability of the temperature zone. When Δt1≤Δt (when the temperature difference is large, such as 18℃ in the second temperature control zone and 5℃ in the first temperature control zone), the fan can be reduced to a low speed of 800RPM (P3). This can reduce the excessive delivery of cooling capacity to the higher temperature zone and avoid the extra energy consumption caused by high speed.

[0022] In one embodiment, S32 includes the following steps: S321. When Δt3 < Δt, adjust the fan speed to reach the fourth rotational speed P4. S322. When △t4<△t≤△t3, adjust the rotation speed of the fan to reach the fifth rotation speed P5; S323. When △t≤△t4, adjust the rotation speed of the fan to reach the sixth rotation speed P6, where P4>P5>P6.

[0023] The above steps enable the wine cabinet with switchable temperature zones to adjust the temperature difference between the temperature control zones in the second operating mode. When Δt3 < Δt (when the temperature difference is small, such as 12℃ for both the second and first temperature control zones), the control fan operates at a high speed of 1800RPM P4, which, in conjunction with the reverse airflow circulation between the cooling space, the second temperature control zone, the circulation space, the first temperature control zone, and the cooling space, quickly and evenly distributes the cooling capacity of the evaporator to the two temperature control zones, avoiding uneven distribution of cooling capacity due to changes in airflow direction, and enabling the two temperature control zones to quickly approach the set temperature; when Δt4 < Δt ≤ Δt3 (when the temperature difference is moderate, such as 10℃ for both the second and first temperature control zones), the temperature difference is adjusted accordingly. When the fan switches to speed P5 at 1500 RPM, it ensures effective circulation of cooling capacity while balancing the distribution of cooling capacity between the two temperature control zones by appropriately reducing the speed, preventing abnormal temperature fluctuations. This forms a closed-loop control with the real-time temperature measurement of the sensor components to maintain temperature stability. When Δt≤Δt4 (when the temperature difference is large, such as 5℃ in the second temperature control zone and 18℃ in the first temperature control zone), the fan drops to a low speed P6 of 800 RPM. This reduces the excessive transfer of cooling capacity to the lower temperature zone, ensuring the low temperature stability of the upper temperature zone, and also reduces the energy consumption of the fan, avoiding energy waste caused by high speed.

[0025] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a wine cabinet with switchable temperature zones and a control method thereof. Example

[0028] like Figures 1 to 6As shown, this embodiment discloses a wine cabinet with switchable temperature zones, including: a cabinet assembly 1, which has a receiving space 101 and a cooling space 102; a cooling assembly 2, which is disposed on the cabinet assembly 1, with a portion of the cooling assembly 2 located in the cooling space 102 and the remaining portion of the cooling assembly 2 located in the receiving space 101; a fan 3, which is disposed on the cabinet assembly 1 and located in the cooling space 102, and is arranged adjacent to the cooling assembly 2; and a partition 4, which is disposed on the cabinet assembly 1 and located in the receiving space 101, dividing the receiving space 101 into a first temperature control zone 1011 and a second temperature control zone 1012. A circulation space 401 is provided; the fan 3 can rotate in a first direction or a second direction. When the fan 3 rotates in the first direction, the cooling space 102, the first temperature control zone 1011, the circulation space 401, the second temperature control zone 1012 and the cooling space 102 are sequentially and cyclically connected. The temperature of the first temperature control zone 1011 is less than or equal to the temperature of the second temperature control zone 1012. When the fan 3 rotates in the second direction, the cooling space 102, the second temperature control zone 1012, the circulation space 401, the first temperature control zone 1011 and the cooling space 102 are sequentially and cyclically connected. The temperature of the first temperature control zone 1011 is greater than or equal to the temperature of the second temperature control zone 1012. The first direction and the second direction are opposite.

[0029] This application discloses a wine cabinet with switchable temperature zones. Existing wide-range temperature-controlled dual-temperature-zone wine cabinets require two independent refrigeration systems, and non-wide-range temperature-controlled solutions also require at least two fan motors, both of which suffer from high cost and high energy consumption. In contrast, this wine cabinet relies on only one set of refrigeration components 2 and a single fan 3. Temperature zone switching is achieved by changing the direction of the fan 3, eliminating the need for additional evaporators and motor loads, significantly reducing equipment manufacturing costs and energy consumption from motor operation. Furthermore, existing solutions occupy a large amount of internal space due to the layout of multiple components, resulting in limited actual wine storage capacity. This wine cabinet simplifies the internal structure, eliminating redundant evaporators and motors, and achieving space division only through a middle partition 4. Moreover, the design of the circulation space 401 of the middle partition 4 does not affect the overall storage layout, maximizing the utilization of the storage space 101 of the cabinet component 1. Furthermore, this wine cabinet overcomes the limitations of existing non-wide-range temperature control solutions with fixed temperature zone functions. Existing solutions, once designed, cannot change the temperature range of the two zones, failing to meet users' flexible wine storage needs. For example, it's impossible to change the original 5-12℃ setting of the first temperature control zone 1011 to 12-18℃ for storing red wine, while simultaneously storing sparkling wine in the second temperature zone 1012. This wine cabinet, however, controls the airflow circulation direction by rotating the fan 3 in either the first or second direction. When the fan 3 rotates in the first direction, the cooling space 102, the first temperature control zone 1011, the circulation space 401, the second temperature control zone 1012, and the cooling space 102 are sequentially and cyclically connected, ensuring that the temperature of the first temperature control zone 1011 is less than or equal to that of the second temperature control zone 1012. When the fan 3 rotates in the second direction, the cooling space 102, the second temperature control zone 1012, the circulation space 401, the first temperature control zone 1011, and the cooling space 102 are sequentially and cyclically connected. The temperature of the first temperature control zone 1011 is greater than or equal to the temperature of the second temperature control zone 1012, so that the temperature range of the first temperature control zone 1011 and the second temperature control zone 1012 can be flexibly switched. It can not only meet the basic requirement of 5-12℃ in one temperature zone and 12-18℃ in another temperature zone, but also adjust the temperature range of the two temperature zones at any time according to the changes in wine storage. It perfectly adapts to the storage temperature requirements of different types of wine such as red wine, white wine, and sparkling wine, truly realizing multi-purpose use of one cabinet and greatly improving the functional flexibility of the equipment and the user experience.

[0030] like Figure 1 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the refrigeration component 2 includes an evaporator 21 and a compressor 22. The evaporator 21 is disposed on the housing component 1 and located in the refrigeration space 102. The fan 3 is disposed adjacent to the evaporator 21. The compressor 22 is disposed on the housing component 1 and located in the first temperature control zone 1011. By placing the evaporator 21 adjacent to the fan 3 in the refrigeration space 102, the fan 3 can more efficiently deliver cold energy to each temperature zone, reducing cold energy loss and improving refrigeration efficiency. The compressor 22 is placed in the first temperature control zone 1011, without needing to occupy additional refrigeration space 102 or other areas, optimizing the internal space layout. Combined with the reasonable division of the partition 4, the utilization rate of the storage space 101 is higher. At the same time, this layout makes the division of labor of each component of the refrigeration component 2 clear. In coordination with the fan 3's temperature control mechanism, it can more accurately adjust the temperature of the first temperature control zone 1011 and the second temperature control zone 1012, achieving the advantages of low energy consumption and low cost of a single system, and enhancing temperature control stability.

[0031] like Figure 1 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the evaporator 21 includes an evaporator body 211 and a defrost sensor 212. The evaporator body 211 is disposed on the housing assembly 1 and located in the cooling space 102. The defrost sensor 212 is disposed on the evaporator body 211 and located in the cooling space 102. The defrost sensor 212 is located on the side of the evaporator body 211 closer to the fan 3. By using the evaporator body 211 as the core of cold energy generation, it is stably placed in the cooling space 102 to ensure a continuous supply of cold energy. The defrost sensor 212 is positioned close to the fan 3, which allows for more sensitive detection of frost formation on the surface of the evaporator body 211. Because the airflow is active near the fan 3, frost formation can easily affect airflow circulation. The defrost sensor 212 can detect the thickness of the frost layer in advance to avoid frost accumulation blocking the air duct. This design can trigger the defrosting mechanism in a timely manner to prevent the cold energy delivery from being blocked. It maintains the advantage of efficient cold transfer of the fan 3 and avoids the evaporator body 211 from reducing its cooling efficiency due to frost, thus ensuring the temperature stability of the first temperature control zone 1011 and the second temperature control zone 1012.

[0032] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a main housing 11, a door 12 and a cooling cover 13. The door 12 is disposed on the main housing 11 and can rotate relative to the main housing 11. When the door 12 rotates relative to the main housing 11, it can open or close the accommodating space 101. The cooling cover 13 is disposed on the main housing 11 and cooperates with the main housing 11 to form a cooling space 102. The cooling assembly 2 is disposed on the main housing 11. The fan 3 is disposed on the main housing 11. The partition 4 is disposed on the main housing 11 and / or the cooling cover 13. By using the main housing 11 as the core load-bearing structure, a stable installation foundation is provided for the refrigeration components 2 and the fan 3. At the same time, through the rotational cooperation with the door 12, the door 12 can be flexibly opened or closed to accommodate the space 101, which not only facilitates users to take out and put in wine, but also reduces the loss of cold air in the space 101 and ensures temperature control stability. The refrigeration cover 13 cooperates with the main housing 11 to form an independent refrigeration space 102, providing a closed and suitable working environment for the evaporator body 211, preventing cold air leakage. With the precise defrosting control of the defrosting sensor 212, the refrigeration efficiency is further improved. The partition 4, installed on the main housing 11 and / or the cooling cover 13, precisely divides the accommodating space 101 into a first temperature control zone 1011 and a second temperature control zone 1012. This partition design is the core foundation for achieving independent temperature control in both zones. It can effectively block the random flow of air between the two zones and prevent the cold energy from spreading disorderly between the zones and causing temperature cross-contamination. This provides structural support for the subsequent fan 3 to adjust the airflow circulation direction by reversing the direction of rotation and achieve temperature difference switching between the two zones.

[0033] like Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines that: the cooling space 102 includes a cooling cavity 1021, a first air outlet 1022 and a second air outlet 1023, a portion of the cooling component 2 is located in the cooling cavity 1021, and the fan 3 is located in the cooling cavity 1021 and is arranged opposite to the second air outlet 1023. When the fan 3 rotates in the first direction, the cooling cavity 1021, the first air outlet 1022, the first temperature control zone 1011, the circulation space 401, the second temperature control zone 1012, the second air outlet 1023 and the cooling cavity 1021 are cyclically connected. When the fan 3 rotates in the second direction, the cooling cavity 1021, the second air outlet 1023, the second temperature control zone 1012, the circulation space 401, the first temperature control zone 1011, the first air outlet 1022 and the cooling cavity 1021 are cyclically connected. By utilizing the cooling chamber 1021, an independent and enclosed working environment is provided for the structure of the cooling component 2 and the fan 3, which can reduce the loss of cold energy in the cooling space and ensure the centralized generation and delivery of cold energy. The first air outlet 1022 and the second air outlet 1023 serve as precise channels for airflow to enter and exit the cooling chamber 1021. With the direction control of the fan 3, a clear circulation path is constructed. When the fan 3 rotates in the first direction, the cold energy enters the first temperature control zone 1011 through the first air outlet 1022, and then flows back through the circulation space 401 and the second temperature control zone 1012 from the second air outlet 1023, ensuring that the temperature of the first temperature control zone is lower. When rotating in the second direction, the circulation is reversed, making the temperature of the second temperature control zone even lower. This structured airflow path design avoids the disorderly diffusion of cold energy within the containment space 101, making the temperature difference between the two temperature control zones more stable. At the same time, in conjunction with the temperature zone separation function of the partition 4, it not only continues the low energy consumption advantage of the single system, but also makes the switching between the two temperature zones more efficient and the temperature control more precise. It can more reliably meet the exclusive storage temperature requirements of different types of wine, such as red wine and sparkling wine, and greatly improve the wine storage effect and user experience.

[0034] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the fan 3 is a centrifugal fan. By setting the fan 3 as a centrifugal fan, a stronger and more stable airflow can be formed in the cooling chamber 1021. With the arrangement opposite to the second air outlet 1023, the cold energy generated by the cooling component 2 can be efficiently delivered to the first air outlet 1022 or the second air outlet 1023, reducing the attenuation of the airflow in the circulation path and ensuring that the cold energy quickly and evenly covers the first temperature control zone 1011 and the second temperature control zone 1012.

[0035] like Figure 1As shown, in addition to the features of the above embodiments, this embodiment further specifies that the fan 3 is an axial flow fan. By setting the fan 3 as an axial flow fan, it has the advantages of large airflow, moderate air delivery distance and low operating noise. Combined with its layout opposite to the second air outlet 1023, it can form a stable and wide-coverage airflow in the cooling chamber 1021, efficiently delivering the cold energy generated by the cooling component 2 to the first air outlet 1022 or the second air outlet 1023, avoiding local cold energy accumulation, and ensuring the temperature uniformity between the first temperature control zone 1011 and the second temperature control zone 1012.

[0036] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the door 12 is a glass door. By making the door 12 a glass door, the user can clearly observe the storage status of the wine in the first temperature control zone 1011 and the second temperature control zone 1012 within the storage space 101 without opening the door, avoiding the loss of cold air due to frequent door opening. This ensures the temperature stability of the dual temperature zones and reduces the additional energy consumption of the refrigeration component 2, which is consistent with the low energy consumption advantage of the single system.

[0037] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the door 12 is a foamed door. By making the door 12 a foamed door, the heat exchange between the storage space 101 and the outside world can be significantly reduced, avoiding interference from external high or low temperatures on the temperatures of the first temperature control zone 1011 and the second temperature control zone 1012, effectively maintaining a constant temperature in both temperature zones, and providing a more stable storage environment for wines such as red wine and sparkling wine. At the same time, the excellent thermal insulation can reduce the operating load of the refrigeration component 2, reduce the start-stop frequency of the compressor 22 and the fan 3, and further save energy consumption while continuing the low energy consumption advantage of the single system.

[0038] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the circulation space 401 includes a first air outlet 4011, a circulation channel 4012, and a second air outlet 4013. When the fan 3 rotates in the first direction, the cooling space 102, the first temperature control zone 1011, the first air outlet 4011, the circulation channel 4012, the second air outlet 4013, the second temperature control zone 1012, and the cooling space 102 are sequentially and cyclically connected. When the fan 3 rotates in the second direction, the cooling space 102, the second temperature control zone 1012, the second air outlet 4013, the circulation channel 4012, the first air outlet 4011, the first temperature control zone 1011, and the cooling space 102 are sequentially and cyclically connected. By refining the circulation space 401 into the first air outlet 4011, the circulation channel 4012, and the second air outlet 4013, the airflow within the accommodating space 101 becomes more directional. When the fan 3 rotates in the first direction, the cooling energy enters the first temperature control zone 1011 from the cooling space 102, and then precisely enters the circulation channel 4012 through the first air vent 4011. It then flows smoothly into the second temperature control zone 1012 through the second air vent 4013, and finally returns to the cooling space 102. This avoids temperature disturbances caused by disordered airflow diffusion, ensuring that the temperature of the first temperature control zone 1011 is lower than that of the second temperature control zone 1012. When the fan 3 rotates in the second direction, the airflow reverses, passing through the second air vent 4013, the circulation channel 4012, and the first air vent 4011, stabilizing the effect of a lower temperature in the second temperature control zone 1012. Simultaneously, the circulation channel 4012 reduces cooling energy loss during zone transitions. Combined with the partition 4 and the cooling energy supply from the cooling component 2, this maintains the advantages of low energy consumption and low cost of a single system, while also making the temperature difference between the two temperature control zones more stable and the temperature regulation more precise. Furthermore, the first air vent 4011 and the second air vent 4013 can be designed as a grille structure or a perforated plate structure to improve airflow efficiency.

[0039] like Figure 1 , Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further includes a sensor assembly 5, which comprises a first sensor 51 and a second sensor 52. The first sensor 51 is disposed on the housing assembly 1 and located on the side wall of the housing assembly 1, in the first temperature control zone 1011. The second sensor 52 is disposed on the housing assembly 1 and located on the side wall of the housing assembly 1, in the second temperature control zone 1012. By disposing the first sensor 51 and the second sensor 52 on the side wall of the housing assembly 1 and correspondingly located in the first temperature control zone 1011 and the second temperature control zone 1012, the two sensors can collect temperature data of their respective temperature control zones in real time and independently, avoiding misjudgments of regional temperature differences caused by single-sensor temperature measurement. When the temperature of the first temperature control zone 1011 or the second temperature control zone 1012 deviates from the set value, it can be quickly fed back to the control system to adjust the direction of the fan 3 and the operating status of the cooling component 2 in a timely manner. Example

[0040] like Figures 1 to 10 As shown, this embodiment discloses a control method for a wine cabinet with switchable temperature zones. The control method for the wine cabinet with switchable temperature zones includes the following steps: S1. Set the temperature of the first temperature control zone T1 and the temperature of the second temperature control zone T2, and calculate the set temperature difference Δt between the first temperature control zone and the second temperature control zone. Δt = T2 - T1. The wine cabinet with switchable temperature zones has at least a first working mode and a second working mode. When the wine cabinet with switchable temperature zones is in the first working mode, Δt ≥ 0℃. When the wine cabinet with switchable temperature zones is in the second working mode, Δt ≤ 0℃. S2. Start the cooling component 2 so that the cold energy released by the cooling component 2 circulates in the wine cabinet with switchable temperature zones. According to the working mode set by the wine cabinet with switchable temperature zones, start the fan 3 and adjust the rotation direction of the fan 3. When the wine cabinet with switchable temperature zones is set to the first working mode, set the rotation direction of the fan 3 to the first direction. When the wine cabinet with switchable temperature zones is set to the second working mode, set the rotation direction of the fan 3 to the second direction. S3. Based on the working mode of the wine cabinet with switchable temperature zones, set the preset temperature difference, compare the magnitude of the set temperature difference Δt with the preset temperature difference, and adjust the rotation speed of the fan 3.

[0041] The second aspect of this application discloses a control method for a wine cabinet with switchable temperature zones. First, by setting T1 and T2 and calculating Δt, combined with the division of the first and second working modes (Δt≥0℃ or ≤0℃), the method accurately matches the dual-temperature zone switching requirements of the wine cabinet, solving the problem of fixed temperature zone functions in existing wine cabinets. Users can flexibly define the temperature relationship between the upper and lower temperature zones according to the storage needs of different types of wine, such as red wine and sparkling wine, resulting in stronger adaptability. Second, the direction of the fan 3 is adjusted according to the working mode, coordinating with the air outlet layout of the wine cabinet's cooling space 102 and the airflow structure of the circulation space 401 to ensure that the cold air circulates along a preset path, avoiding disordered loss of cold air. This, combined with the efficient cooling supply of the cooling component 2, improves the cooling efficiency. Finally, based on the preset temperature difference set according to the mode, the fan speed of 3 is adjusted in stages by comparing Δt with the preset temperature difference. This avoids the problem of low temperature difference control accuracy caused by single-speed operation, and allows for rapid temperature uniformity at a higher speed when the temperature difference is small, and precise temperature control at a lower speed when the temperature difference is large, reducing ineffective energy consumption of the fan and continuing the low energy consumption advantage of a single system.

[0042] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: S3 includes the following steps: S31. When the wine cabinet with switchable temperature zones is in the first working mode, a first preset temperature difference △t1 and a second preset temperature difference △t2 are set. The magnitude relationship between the set temperature difference △t and the first preset temperature difference △t1 and the second preset temperature difference △t2 is compared, and the rotation speed of the fan 3 is adjusted, wherein △t1>△t2>0℃. S32. When the wine cabinet with switchable temperature zones is in the second working mode, set the third preset temperature difference △t3 and the fourth preset temperature difference △t4, compare the magnitude relationship between the set temperature difference △t and the third preset temperature difference △t3 and the fourth preset temperature difference △t4, and adjust the rotation speed of the fan 3, wherein 0℃>△t3>△t4.

[0043] By classifying △t1 and △t2 in the first working mode △t≥0℃, the speed can be flexibly matched according to the actual temperature difference requirements: when △t is large (such as close to the upper limit of the maximum temperature difference of the wine cabinet), the speed is adjusted to a low speed according to △t1 to accurately control the distribution of cooling capacity and maintain a stable temperature difference; when △t is small (such as when the first and second temperature control zones need to be close), the speed is switched to a higher speed according to △t2 to quickly achieve uniform temperature and avoid temperature control lag or energy waste caused by a single-level preset temperature difference. In the second working mode △t≤0℃, the classification of △t3 and △t4 is similar to adapt to the temperature difference control requirements under reverse airflow circulation, ensuring that the speed adjustment of fan 3 is deeply coordinated with the cooling capacity circulation path and the airflow efficiency of the middle partition flow space 401. This refined setting not only realizes the core advantage of adjusting the speed according to the temperature difference, but also makes the speed adjustment more in line with the needs of different temperature zones through patterned and differentiated presets. Combined with the efficient cooling of the refrigeration component 2 and the real-time temperature measurement of the sensor component 5, it further reduces ineffective energy consumption, improves the stability of dual-temperature zone temperature control, better meets the temperature accuracy requirements of diverse wine storage such as red wine, white wine, and sparkling wine, and enhances the user's professional wine storage experience.

[0044] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines: S31 includes the following steps: S311. When Δt < Δt2, adjust the rotation speed of fan 3 to reach the first rotation speed P1; S312. When △t2≤△t<△t1, adjust the rotation speed of fan 3 to reach the second rotation speed P2; S313. When △t1≤△t, adjust the rotation speed of fan 3 to reach the third rotation speed P3, where P1>P2>P3.

[0045] The above steps enable the wine cabinet with switchable temperature zones to adjust the temperature difference between the temperature control zones in the first working mode. When Δt < Δt2 (when the temperature difference is small, such as the second temperature control zone 1012 being 12℃ and the first temperature control zone 1011 being 12℃), the fan 3 is controlled to run at a high speed P1 of 1800RPM, which can quickly circulate the cold energy generated by the evaporator 21 through the cooling space 102, the first temperature control zone 1011, the circulation space 401, the second temperature control zone 1012, and the cooling space 102, reducing the stagnation of cold energy in the circulation path and achieving rapid and uniform temperature in the two temperature control zones, avoiding the problem of slow temperature equalization caused by insufficient speed; when Δt2 ≤ Δt < When the temperature difference is moderate (e.g., 14℃ in the second temperature control zone and 10℃ in the first temperature control zone), the fan 3 switches to speed P2 at 1500 RPM. While ensuring effective delivery of cooling capacity, the fan adjusts the cooling capacity distribution ratio by appropriately reducing the speed to prevent the temperature difference from further shrinking or expanding, thus maintaining a stable temperature in the temperature zone. When the temperature difference is large (e.g., 18℃ in the second temperature control zone and 5℃ in the first temperature control zone), the fan 3 drops to a low speed P3 of 800 RPM. This reduces the excessive delivery of cooling capacity to the higher temperature zone and avoids the extra energy consumption caused by high speed.

[0046] like Figure 8 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further defines: S32 includes the following steps: S321. When Δt3 < Δt, adjust the rotation speed of fan 3 to reach the fourth rotation speed P4. S322. When △t4<△t≤△t3, adjust the rotation speed of fan 3 to reach the fifth rotation speed P5; S323. When △t≤△t4, adjust the rotation speed of fan 3 to reach the sixth rotation speed P6, where P4>P5>P6.

[0047] The above steps enable the wine cabinet with switchable temperature zones to adjust the temperature difference between the temperature control zones in the second working mode. When Δt3 < Δt (when the temperature difference is small, such as the second temperature control zone 1012 being 12℃ and the first temperature control zone 1011 being 12℃), the control fan 3 operates at a high speed P4 of 1800RPM, which can cooperate with the reverse airflow to circulate the cooling space 102, the second temperature control zone 1012, the circulation space 401, the first temperature control zone 1011, and the cooling space 102, quickly and evenly delivering the cooling capacity of the evaporator 21 to the two temperature control zones, avoiding uneven distribution of cooling capacity due to changes in airflow direction, and enabling the two temperature control zones to quickly approach the set temperature; when Δt4 < Δt ≤ Δt3 (when the temperature difference is moderate, such as the second temperature control zone 1012 being 10 ... cooling space 1012, the second temperature control (Control zone 1011 is 14℃), the fan 3 switches to speed P5 of 1500RPM. While ensuring effective circulation of cooling capacity, it balances the distribution of cooling capacity between the two temperature control zones by appropriately reducing the speed, preventing abnormal temperature fluctuations. This forms a closed-loop control with the real-time temperature measurement of sensor component 5 to maintain temperature stability. When Δt≤Δt4 (when the temperature difference is large, such as when the second temperature control zone 1012 is 5℃ and the first temperature control zone 1011 is 18℃), the fan 3 can be reduced to a low speed P6 of 800RPM. This can reduce the excessive transfer of cooling capacity to the lower temperature zone, ensuring the low temperature stability of the upper temperature zone, and also reduce the energy consumption of the fan operation, avoiding energy waste caused by high speed.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
