Description

Technical Field

[0001] This invention relates to the field of wine cabinets, and in particular to a wine cabinet with a concealed noise-reducing fan structure. Background Technology

[0002] Traditional wine cabinets generally suffer from structural design flaws. The fans and protective mesh covers are directly exposed inside the storage cavity without any concealed storage structure. Over time, dust easily accumulates in the gaps of the exposed mesh covers, and the complex structure and narrow gaps make thorough cleaning difficult. Furthermore, the exposed layout results in a cluttered and unsightly interior, with various fan components and mesh covers directly exposed, completely ruining the overall neatness and aesthetics of the storage space and significantly lowering the product's premium feel, failing to meet the display and usage requirements of high-end wine cabinets. Moreover, traditional wine cabinet fans lack sound insulation and noise reduction structures. The mechanical noise and airflow noise generated during operation radiate directly outwards into the storage cavity and the external space without any buffering or obstruction. The overall operating noise is relatively high, easily disturbing the tranquility of the indoor environment and seriously affecting the user's daily experience. Summary of the Invention

[0003] Therefore, it is necessary to address the problem of unreasonable fan structure design in wine cabinets by providing a wine cabinet with a concealed noise-reducing fan structure.

[0004] A wine cabinet with a concealed noise-reducing fan structure includes: a cabinet assembly having a receiving cavity; at least one partition, which is detachable from the cabinet assembly and can divide the receiving cavity into at least two storage spaces; and at least two air duct structures disposed on the cabinet assembly and located on its inner sidewall, with each air duct structure corresponding to the other. In at least two of the storage spaces; the air duct structure includes an air guide plate, a fan assembly, an evaporator, and noise reduction components. The air guide plate is disposed on the housing assembly. The fan assembly is disposed on the air guide plate and located on the side of the air guide plate away from the storage space. The fan assembly is located between the air guide plate and the housing assembly. The evaporator is disposed on the housing assembly. There are multiple noise reduction components, some of which are sandwiched between the air guide plate and the fan assembly, and the remaining noise reduction components are sandwiched between the air guide plate and the evaporator.

[0005] The aforementioned disclosure describes a wine cabinet with a concealed noise-reducing fan structure. By optimizing the air duct layout, selecting a specific fan, and adding noise-reducing components, it comprehensively addresses the core pain points of traditional wine cabinets, such as high noise levels, cluttered appearance, inconvenient cleaning, and temperature cross-contamination, significantly improving the user experience and premium quality. Compared to traditional wine cabinets that use axial flow fans, where noise radiates directly into the cabinet without buffering or blocking structures, resulting in high overall noise levels that easily disturb the indoor environment and are unsuitable for high-end home settings, this air duct structure uses a centrifugal fan. Combined with multiple noise-reducing components and a concealed air duct layout, the centrifugal fan itself operates at a lower noise level. Furthermore, the fan component is positioned between the air guide plate and the cabinet assembly, and with multiple noise-reducing components sandwiched between the air guide plate, the fan component, and the evaporator, noise is effectively blocked from being transmitted outward, significantly reducing overall operating noise and achieving quiet operation to meet the needs of quiet wine storage. Addressing the issue of traditional wine cabinets where the fan components are directly exposed inside the cabinet cavity, resulting in a cluttered internal structure, compromising the overall aesthetics of the product, lowering the image of a high-end product and the display effect of wine, and making it easy for dust and wine stains to accumulate on the exposed fan cover, making subsequent cleaning and maintenance difficult and cumbersome; this air duct structure is entirely hidden on the inner wall of the cabinet components, with the fan components completely housed behind the air guide plate, without taking up storage space. The internal layout is neat and simple, showcasing a high-end feel, while eliminating exposed dust accumulation corners and making daily cleaning more convenient. Furthermore, traditional dual-temperature zone wine cabinets lack independent air ducts, making them prone to temperature cross-contamination between the upper and lower temperature zones. This results in poor temperature control accuracy and fails to meet the zoned, constant-temperature storage requirements for different types of wine, such as red and white wine. This design, however, features at least two independent air duct structures for each of the at least two storage spaces. Each air duct structure independently supplies air and controls temperature for one temperature zone, eliminating interference and preventing temperature cross-contamination at its source. This achieves independent and precise temperature control for both zones, perfectly adapting to the differentiated storage requirements of high-end wines while balancing practicality and product prestige. When the two storage spaces are not needed, the partition can be removed, making the wine cabinet's interior a single unit. In this case, only one air duct structure is required, enabling various usage scenarios.

[0006] In one embodiment, the air guide plate and the housing assembly cooperate to form a condensation space. The fan assembly and the evaporator are located in the condensation space. The air guide plate has an air inlet space and an air outlet space, and the fan assembly has a flow guiding space. The storage space, the air inlet space, the condensation space, the flow guiding space, the air outlet space, and the storage space are sequentially and cyclically connected. By completely housing the fan assembly and the evaporator within the sealed condensation space, the core heat exchange components are prevented from being exposed. This prevents dust and moisture from directly adhering to and corroding the components, extending the service life of the fan assembly and the evaporator. It also blocks the noise from spreading outward during heat exchange operation. Combined with the overall concealed layout, the quietness effect is further enhanced. The design utilizes a sequentially interconnected storage space, air intake space, condensation space, air diversion space, air outlet space, and return airflow space to form a stable and orderly closed-loop airflow path with upper air outlet and lower air return. Cool air is evenly delivered from the air outlet space to the upper part of the storage space, flows smoothly from top to bottom, and then returns from the lower air intake space to the condensation space to complete heat exchange. The entire process is free of turbulence and dead zones, ensuring highly uniform temperature throughout the storage space and preventing excessive local temperature differences. For dual-temperature zone storage design, this independent closed-loop airflow allows each temperature zone to circulate independently, fundamentally preventing cross-flow of hot and cold air between the upper and lower temperature zones. This ensures precise and controllable temperature control in each storage space, perfectly adapting to the differentiated storage needs of various wines. Simultaneously, the closed-loop heat exchange efficiency is higher, effectively reducing overall energy consumption.

[0007] In one embodiment, there are multiple air inlet spaces, arrayed on the air guide plate and located on the side of the air guide plate away from the top of the housing assembly. These multiple air inlet spaces are positioned opposite the evaporator. By concentrating the multiple air inlet spaces on the bottom side of the air guide plate away from the top of the housing assembly and precisely positioning them opposite the evaporator, a closed-loop airflow path of upper air outlet and lower air return is achieved. This ensures that the cold air in the storage space flows evenly from top to bottom and then quickly and unobstructedly returns in all directions, avoiding the problem of large local temperature differences caused by airflow stagnation and poor return airflow at the bottom. This ensures a uniform temperature throughout the storage space, meeting the stringent temperature and humidity requirements for high-end wines. Furthermore, the arrayed multi-air inlet space design significantly increases the return air contact area compared to a single air inlet. After entering the condensation space, the airflow can directly and evenly cover the evaporator surface, allowing for more thorough and balanced heat exchange. This prevents excessive or insufficient heat exchange in certain areas, effectively improving cooling efficiency and reducing overall energy consumption. Meanwhile, the multi-air intake array disperses the return air pressure, avoiding the vortex noise generated by the concentrated impact of airflow in a single air intake space. Combined with the hidden condensation space and noise reduction components, it further reduces the overall operating noise of the unit, achieving silent return air.

[0008] In one embodiment, the air inlet space extends along the length of the air guide plate. By utilizing the elongated design of the air inlet space, it maximizes the fit to the overall size of the air guide plate, achieving full-length coverage of the bottom return air area. This completely eliminates dead air corners on both sides of the bottom of the storage space, allowing the cold air flowing from top to bottom inside the box to evenly converge into the condensation space. This avoids temperature deviations caused by insufficient local return air, further ensuring uniform temperature and humidity throughout the box. Simultaneously, the elongated air inlet space can be coordinated with the overall length of the evaporator to achieve full-width airflow alignment, ensuring that the return airflow evenly covers the entire heat exchange surface of the evaporator, eliminating local heat exchange blind spots, improving overall cooling and heat exchange efficiency, and reducing energy consumption.

[0009] In one embodiment, there are multiple air outlet spaces, distributed on both sides of the air guide plate, with the air outlet spaces located on the side of the air guide plate closest to the top of the cabinet assembly. Through multiple sets of top air outlet spaces on both sides, cold air can be simultaneously and evenly delivered from the upper left and right sides of the storage space, avoiding localized cold air accumulation and large temperature differences on the other side caused by single-sided airflow. This allows cold air to smoothly cover the entire storage space from top to bottom, completely eliminating dead zones in the airflow within the cabinet and ensuring a high degree of temperature and humidity uniformity in every storage area, meeting the stringent requirements for constant temperature storage of high-end wines and other beverages. Combined with the long, extended air inlet space at the bottom, the cold air can smoothly return in all directions after heat exchange. The long, extended air inlet space can be aligned with the overall length of the evaporator to achieve full-width airflow connection, allowing the return airflow to evenly cover the entire heat exchange surface of the evaporator, eliminating localized heat exchange blind spots, improving overall cooling and heat exchange efficiency, and reducing energy consumption.

[0010] In one embodiment, the air outlet space extends along the width direction of the air guide plate. By utilizing the design of the air outlet space extending along the width direction of the air guide plate, compared with point-like or narrow-width air outlet structures, the wide-width extended air outlet can expand the coverage range of a single air outlet. Combined with the distribution layout on both sides of the air guide plate, it achieves wide-width air supply throughout the top of the box. After the cold air is delivered, it is easier to spread evenly, avoiding the problems of local cold air concentration and surrounding temperature lag caused by narrow-width air outlets, and completely eliminating dead zones in the upper air supply.

[0011] In one embodiment, the fan assembly includes a mounting plate, a fixing plate, and a fan body. The mounting plate is disposed on the air guide plate and located on the side away from the storage space. The fixing plate is disposed on the air guide plate and / or the mounting plate. The mounting plate and the fixing plate cooperate to form a flow guide space. The fan body is disposed on the fixing plate and located between the mounting plate and the fixing plate. The fan body is located in the flow guide space. Some of the noise reduction components are disposed on both sides of the mounting plate and sandwiched between the mounting plate and the air guide plate. By completely housing the centrifugal fan body within the flow guide space formed by the mounting plate and the fixing plate, and placing the entire assembly on the side of the air guide plate away from the storage space, a fully concealed layout of the fan assembly is achieved. No fan components are exposed in the storage space, resulting in a neat and simple internal space that showcases the exquisite texture and aesthetics of a high-end wine cabinet. This does not disrupt the overall visual effect of the wine display and meets the needs of high-end home and commercial wine storage scenarios. Meanwhile, the entire fan assembly is housed within the condensation space, eliminating the protective mesh structure of traditional exposed fans. This fundamentally avoids the problems of dust accumulation and wine stains in the mesh gaps, preventing mesh blockage and difficult-to-clean dirt. Daily cleaning of the wine cabinet's interior requires no additional attention to the fan area, significantly simplifying the cleaning and maintenance process and saving time and effort. Furthermore, the fan body is enclosed within the airflow guide space, forming a double noise barrier with noise reduction components located on both sides of the mounting plate and sandwiched between the mounting plate and the airflow guide plate. This effectively blocks the motor vibration noise during fan operation and reduces airflow noise within the duct, preventing noise from spreading into the storage space and to the outside. Compared to traditional exposed fans, the overall airflow noise and motor noise are significantly reduced.

[0012] In one embodiment, the fan assembly further includes multiple seals sandwiched between the mounting plate and the air guide plate. By tightly filling the assembly gap between the mounting plate and the air guide plate with multiple sets of seals, and because the seals are made of foam, a sealing barrier can be achieved at the side of the air guide space, completely preventing airflow leakage and turbulence from the assembly gap. This ensures that all airflow delivered by the fan body is directed into the top air outlet space, avoiding airflow loss, significantly improving cooling and heat exchange efficiency, and maintaining a stable closed-loop airflow of upper air outlet and bottom return. Furthermore, the foam seals further reduce noise emissions.

[0013] In one embodiment, the fan assembly further includes multiple seals sandwiched between the mounting plate and the fixing plate. By tightly filling the assembly gap between the mounting plate and the fixing plate with multiple sets of seals, the seals, being made of foam, can seal the sides of the enclosed airflow space, preventing airflow leakage from the joints during centrifugal fan operation. This ensures efficient and directional airflow delivery, avoids airflow loss, significantly improves airflow delivery efficiency, stabilizes the closed-loop circulation system of upper air outlet and bottom air return, and guarantees uniform and accurate temperature control within the enclosure. Furthermore, the foam seals can block vibration and noise from being transmitted and diffused outwards through the rigid plate joints.

[0014] In one embodiment, the fan assembly further includes multiple seals sandwiched between the fixed plate and the air guide plate. By tightly fitting multiple sets of seals to the mating surfaces of the fixed plate and the air guide plate, the seals, being made of foam, possess flexible vibration damping and porous sound absorption characteristics. On the one hand, they tightly seal the assembly gaps of the plates, preventing eddy noise generated by airflow through the gaps. On the other hand, they effectively buffer the mechanical vibrations caused by the operation of the centrifugal fan, blocking the transmission and diffusion of vibration noise through the rigid plate joints. Combined with the original noise reduction components, this forms a triple noise reduction barrier of sound absorption, vibration damping, and sealing, resulting in a more prominent quieting effect than ordinary rigid seals, significantly reducing motor operating noise and airflow turbulence noise.

[0015] In one embodiment, the air guide plate includes a main air guide plate and connecting foam. The main air guide plate is disposed on the housing assembly and located on the inner wall of the housing assembly. Multiple connecting foams are sandwiched between the main air guide plate and the housing assembly. The fan assembly is disposed on the main air guide plate. By utilizing the connecting foam, which is a flexible cushioning material, it effectively blocks the mechanical vibration generated by the fan assembly, preventing the vibration from being directly transmitted to the housing assembly and causing resonance noise. This weakens noise transmission at the source of vibration. Combined with the foam seals and noise reduction components in the fan area, it forms a full-link sound absorption and vibration reduction barrier, significantly reducing the overall operating noise and creating a quieter wine storage environment. Furthermore, multiple sets of connecting foam tightly fill the assembly gap between the main air guide plate and the housing assembly, achieving a complete seal at the edge of the air duct. This prevents airflow leakage from the side gaps in the condensation space, ensuring stable closed-loop airflow with air outlet at the top and return at the bottom, avoiding airflow loss, and improving the uniformity of cooling and heat exchange and temperature control.

[0016] In one embodiment, the air guide plate further includes multiple decorative covers, which are positioned at the connection between the main air guide plate and the housing assembly. By completely covering the seams between the main air guide plate and the housing assembly with multiple sets of decorative covers, internal seam marks are eliminated, resulting in a smoother and cleaner inner wall of the housing assembly, free of exposed seams, connectors, or assembly defects. This maintains a neat and uniform visual effect inside the housing, maximizing the display of the product's high-end and refined attributes without compromising the aesthetics of the wine storage space.

[0017] In one embodiment, the air duct structure further includes a liquid receiving housing, which is disposed on the housing assembly and opposite to the evaporator. The air guide plate also includes a guide plate, which is disposed on the main air guide plate and extends towards the liquid receiving housing. By providing a liquid receiving housing opposite to the evaporator, combined with the guide plate extending towards the liquid receiving housing on the main air guide plate, the problem of condensate accumulation and leakage during the evaporator cooling process in the wine cabinet is specifically solved. The condensate generated by the evaporator cooling can be smoothly guided along the directional slope of the guide plate to the corresponding liquid receiving housing, preventing condensate from dripping randomly and eliminating problems such as component corrosion and mold growth caused by water accumulation. At the same time, it prevents water from seeping into the air duct gaps and damaging the foam sealing and noise reduction structure, ensuring the long-term sealing and noise reduction effect of the air duct. The liquid receiving housing centrally collects condensate, preventing condensate from dripping onto internal electrical components and ensuring the normal operation of the wine cabinet.

[0018] In one embodiment, the air duct structure further includes a temperature detection element disposed on the air guide plate. The temperature detection element is used to detect the temperature of the storage space. By directly installing the temperature detection element on the air guide plate, close to the core temperature sensing area of ​​the storage space, and avoiding local temperature interference from heat exchange and air supply components such as the evaporator and fan assembly, the true and stable real-time temperature inside the box can be accurately collected, eliminating temperature measurement deviations. Combined with the dual-temperature zone independent air duct design, independent temperature measurement and individual temperature adjustment can be achieved for each storage space, fundamentally avoiding the drawbacks of temperature cross-contamination between upper and lower temperature zones and temperature control lag. This ensures that the temperature and humidity of each storage area remain constant and meet standards, adapting to the differentiated storage temperature requirements of different wines such as red wine and white wine. Simultaneously, real-time accurate temperature measurement can intelligently start and stop the fan and refrigeration system, avoiding continuous high-load operation, reducing unnecessary energy consumption, and balancing energy saving and temperature control stability.

Detailed Implementation

[0021] 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.

[0022] 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.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the wine cabinet with a concealed noise-reducing fan structure. Example

[0024] like Figures 1 to 10 As shown, this embodiment discloses a wine cabinet with a concealed noise-reducing fan structure, including: a cabinet assembly 1, the cabinet assembly 1 having a receiving cavity 101; a partition 2, the number of partitions 2 being at least one, the at least one partition 2 being detachable from the cabinet assembly 1, the at least one partition 2 being able to divide the receiving cavity 101 into at least two storage spaces 1011; and an air duct structure 100, the number of air duct structures 100 being at least two, the at least two air duct structures 100 being disposed on the cabinet assembly 1 and located on the inner side wall of the cabinet assembly 1, the at least two air duct structures 100 corresponding one-to-one. It is placed in at least two storage spaces 1011; the air duct structure 100 includes an air guide plate 3, a fan assembly 4, an evaporator 5 and a noise reduction component 6. The air guide plate 3 is disposed on the housing assembly 1. The fan assembly 4 is disposed on the air guide plate 3 and located on the side of the air guide plate 3 away from the storage space 1011. The fan assembly 4 is located between the air guide plate 3 and the housing assembly 1. The evaporator 5 is disposed on the housing assembly 1. There are multiple noise reduction components 6. Some noise reduction components 6 are sandwiched between the air guide plate 3 and the fan assembly 4, and the remaining noise reduction components 6 are sandwiched between the air guide plate 3 and the evaporator 5.

[0025] This application discloses a wine cabinet with a concealed noise-reducing fan structure. By optimizing the air duct layout, selecting a specific fan, and adding noise-reducing components, it comprehensively solves the core pain points of traditional wine cabinets, such as high noise, cluttered appearance, inconvenient cleaning, and temperature cross-contamination, significantly improving the user experience and high-end quality of the product. Compared to the traditional wine cabinet design using axial flow fans, where noise radiates directly into the cabinet without buffering or blocking structures, resulting in high overall operating noise that easily disturbs the indoor environment and is unsuitable for high-end home settings, the fan component 4 of this air duct structure 100 uses a centrifugal fan. Combined with multiple sets of noise-reducing components 6 and the concealed air duct layout, the centrifugal fan itself operates at a lower noise level. Furthermore, the fan component 4 is located between the air guide plate 3 and the cabinet component 1. With the multiple sets of noise-reducing components 6 sandwiched between the air guide plate 3, the fan component 4, and the evaporator 5, noise is effectively blocked from being transmitted outward, significantly reducing the overall operating noise and achieving quiet operation to meet the needs of quiet wine storage. Addressing the issue of traditional wine cabinets where the fan components are directly exposed within the housing cavity 101, resulting in a cluttered internal structure, compromising the overall aesthetics of the product, lowering the image of a high-end product and the display effect of wine, and making it easy for dust and wine stains to accumulate on the exposed fan cover, making subsequent cleaning and maintenance difficult and cumbersome; this air duct structure is entirely concealed within the inner wall of the cabinet component 1, with the fan component 4 completely housed behind the air guide plate 3, without occupying storage space. The internal layout is neat and simple, showcasing a high-end feel, while eliminating exposed dust accumulation dead corners and making daily cleaning more convenient. Furthermore, traditional dual-temperature zone wine cabinets lack independent air ducts, making them prone to temperature cross-contamination between the upper and lower temperature zones. This results in poor temperature control accuracy and fails to meet the zoned constant temperature storage requirements for different types of wine, such as red and white wine. This design, however, features at least two independent air duct structures 100 corresponding to at least two storage spaces 1011. Each air duct structure 100 independently supplies air to and controls the temperature of one temperature zone, eliminating interference and preventing temperature cross-contamination at its source. This achieves independent and precise temperature control for both zones, perfectly adapting to the differentiated storage requirements of high-end wines while balancing practicality and product quality. When the two storage spaces 1011 are not needed, the partition 2 can be removed, making the wine cabinet's storage cavity 101 a single unit. In this case, only one air duct structure 100 is required, enabling various usage scenarios.

[0026] like Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air guide plate 3 and the housing assembly 1 cooperate to form a condensation space 102, the fan assembly 4 and the evaporator 5 are located in the condensation space 102, the air guide plate 3 is provided with an air inlet space 301 and an air outlet space 302, the fan assembly 4 is provided with a flow guiding space 401, and the storage space 1011, the air inlet space 301, the condensation space 102, the flow guiding space 401, the air outlet space 302 and the storage space 1011 are sequentially and cyclically connected. By completely housing the fan assembly 4 and the evaporator 5 in the sealed condensation space 102, the core heat exchange components are prevented from being exposed, which not only prevents dust and water vapor from directly adhering to and corroding the components, extending the service life of the fan assembly 4 and the evaporator 5, but also blocks the noise from spreading outward during heat exchange operation, and further enhances the quietness effect with the overall hidden layout. The design utilizes a sequential connection of storage space 1011, air inlet space 301, condensation space 102, air guide space 401, and air outlet space 302, forming a stable and orderly closed-loop airflow path with upper air outlet and lower air return. Cool air is evenly delivered from the air outlet space 302 into the upper part of storage space 1011, flows smoothly downwards, and then returns from the lower air inlet space 301 to the condensation space 102 to complete heat exchange. The entire process is free of turbulence and dead zones, ensuring highly uniform temperature throughout storage space 1011 and preventing excessive local temperature differences. For dual-temperature zone storage design, this independent closed-loop airflow allows for separate circulation in each temperature zone, fundamentally preventing cross-flow of hot and cold air between the upper and lower temperature zones. This ensures precise and controllable constant temperature in each storage space 1011, perfectly adapting to the differentiated storage needs of various wines. Simultaneously, the closed-loop heat exchange efficiency is higher, effectively reducing overall energy consumption.

[0027] like Figure 3 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of air inlet spaces 301 is multiple, and the multiple air inlet spaces 301 are arrayed on the air guide plate 3 and located on the side of the air guide plate 3 away from the top of the housing assembly 1. The multiple air inlet spaces 301 are arranged opposite to the evaporator 5. By concentrating the multiple air inlet spaces 301 on the bottom side of the air guide plate 3 away from the top of the housing assembly 1, and precisely aligning them with the evaporator 5, on the one hand, it conforms to the closed-loop airflow path of upper side air outlet and bottom side air return, so that after the cold air in the storage space 1011 flows evenly from top to bottom, it can quickly return in all directions without obstruction. This avoids the problem of large local temperature differences caused by bottom airflow stagnation and poor return air, ensuring that the temperature in the entire storage space 1011 is uniform and consistent, meeting the stringent storage requirements of high-end wines for constant temperature and humidity. On the other hand, the array-distributed multi-inlet space 301 design significantly expands the return air contact area compared to a single air inlet. After the airflow enters the condensing space 102, it can directly and evenly cover the surface of the evaporator 5, allowing the evaporator 5 to exchange heat more fully and evenly, eliminating local over- or under-heat exchange, effectively improving cooling efficiency and reducing overall energy consumption. At the same time, the distributed air intake of the multi-inlet space 301 array can disperse the return airflow pressure, avoiding the vortex noise generated by the concentrated impact of airflow in a single air intake space 301. Combined with the hidden condensing space 102 and noise reduction components 6, it further reduces the overall operating noise of the unit, achieving silent return air.

[0028] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines that the air inlet space 301 extends along the length of the air guide plate 3. By utilizing the elongated design of the air inlet space 301, it can maximize the fit with the overall size of the air guide plate 3, achieving full-length coverage of the bottom return air area, completely eliminating the return air dead corners on both sides of the bottom of the storage space 1011, allowing the cold air flowing from top to bottom in the box to evenly converge into the condensation space, avoiding temperature deviations caused by insufficient local return air, and further ensuring uniform temperature and humidity throughout the box. At the same time, the elongated extended air inlet can be matched with the overall length of the evaporator 5 to achieve full-width airflow connection, allowing the return airflow to evenly cover the entire heat exchange surface of the evaporator 5, eliminating local heat exchange blind spots, improving overall cooling and heat exchange efficiency, and reducing energy consumption.

[0029] like Figure 3 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of air outlet spaces 302 is multiple, and the multiple air outlet spaces 302 are respectively arranged on both sides of the air guide plate 3, and the multiple air outlet spaces 302 are located on the side of the air guide plate 3 near the top of the cabinet assembly 1. Through the multiple sets of top air outlet spaces 302 arranged on both sides, cold air can be synchronously and evenly delivered from the upper left and right sides of the storage space 1011, avoiding the situation of local cold air accumulation and large temperature difference on the other side caused by single-sided air outlet, allowing cold air to gently cover the entire storage space 1011 from top to bottom, completely eliminating dead corners in the air supply inside the cabinet, ensuring that the temperature and humidity of each storage area are highly consistent, and meeting the stringent requirements of constant temperature storage for high-end red wine and other wines. With the bottom elongated air inlet space 301, the cold air can flow back smoothly in all directions after being sent out for heat exchange. The elongated air inlet can be matched with the overall length of the evaporator to achieve full airflow connection, so that the return airflow can evenly cover the entire heat exchange surface of the evaporator, eliminating local heat exchange blind spots, improving the overall cooling and heat exchange efficiency, and reducing energy consumption.

[0030] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines that the air outlet space 302 extends along the width direction of the air guide plate 3. By utilizing the design of the air outlet space 302 extending along the width direction of the air guide plate 3, compared with the point-like or narrow-width air outlet structure, the wide-width extended air outlet can expand the coverage range of a single air outlet. Combined with the distribution layout on both sides of the air guide plate 3, it can achieve wide-width air supply throughout the top of the box. After the cold air is delivered, it is easier to spread evenly, avoiding the problems of local cold air concentration and surrounding temperature lag caused by narrow-width air outlet, and completely eliminating the dead corners of upper air supply.

[0031] like Figure 2 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines that: the fan assembly 4 includes a mounting plate 41, a fixing plate 42, and a fan body 43. The mounting plate 41 is disposed on the air guide plate 3 and located on the side away from the storage space 1011. The fixing plate 42 is disposed on the air guide plate 3 and / or the mounting plate 41. The mounting plate 41 and the fixing plate 42 cooperate to form a flow guiding space 401. The fan body 43 is disposed on the fixing plate 42 and is located between the mounting plate 41 and the fixing plate 42. The fan body 43 is located in the flow guiding space 401. Some noise reduction components 6 are disposed on both sides of the mounting plate 41 and sandwiched between the mounting plate 41 and the air guide plate 3. By completely concealing the centrifugal fan body 43 within the airflow guide space 401 formed by the mounting plate 41 and the fixing plate 42, and placing the entire fan assembly 4 on the side of the airflow guide plate 3 away from the storage space 1011, a fully concealed layout is achieved. No fan components are exposed in the storage space 1011, resulting in a neat and simple interior that showcases the exquisite texture and aesthetics of a high-end wine cabinet without compromising the overall visual effect of the wine display. This aligns with the needs of high-end home and commercial wine storage scenarios. Furthermore, the entire fan assembly 4 is completely concealed within the condensation space 102, eliminating the protective mesh structure of traditional exposed fans. This fundamentally avoids the problem of dust accumulation and wine stains in the mesh gaps, preventing mesh blockage and difficult-to-clean dirt. Daily cleaning of the wine cabinet interior requires no additional attention to the fan area, significantly simplifying the cleaning and maintenance process and saving time and effort. In addition, the fan body 43 is enclosed in the airflow space 401. Together with the noise reduction components 6 which are respectively located on both sides of the mounting plate 41 and sandwiched between the mounting plate 41 and the airflow plate 3, a double noise reduction barrier is formed. This can effectively block the motor vibration noise of the fan during operation and weaken the airflow noise in the duct, preventing noise from spreading to the storage space and the outside. Compared with traditional exposed fans, the overall airflow noise and motor noise are greatly reduced.

[0032] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 4 also includes multiple seals, which are sandwiched between the mounting plate 41 and the air guide plate 3. By tightly filling the assembly gap between the mounting plate 41 and the air guide plate 3 with multiple sets of seals, since the seals are made of foam, a sealing barrier can be achieved at the side of the air guide space 401, completely preventing airflow leakage and turbulence from the assembly gap, ensuring that all airflow delivered by the fan body 43 is directed into the top air outlet space 302, avoiding airflow loss, significantly improving cooling and heat exchange efficiency, and maintaining a stable closed-loop airflow of upper air outlet and bottom return. Moreover, the foam material seals can further reduce noise.

[0033] like Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 4 also includes multiple sealing elements, which are sandwiched between the mounting plate 41 and the fixing plate 42. By tightly filling the assembly gap between the mounting plate 41 and the fixing plate 42 with multiple sets of sealing elements, since the sealing elements are made of foam, the sides of the enclosed guiding space 401 can be sealed, preventing airflow from leaking out of the splicing gap during the operation of the centrifugal fan, ensuring that all airflow is transported in a directional and efficient manner, avoiding airflow loss, greatly improving airflow transport efficiency, stabilizing the closed-loop circulation system of upper air outlet and bottom air return, and ensuring uniform and accurate temperature control inside the box. Moreover, the foam material sealing elements can block vibration noise from being transmitted and diffused outward through the splicing of rigid plates.

[0034] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 4 also includes multiple sealing elements, which are sandwiched between the fixed plate 42 and the air guide plate 3. By tightly fitting multiple sets of sealing elements to the mating surfaces of the fixed plate 42 and the air guide plate 3, the sealing elements, being made of foam, possess flexible vibration damping and porous sound absorption characteristics. On the one hand, they tightly seal the assembly gaps of the plates, preventing eddy wind noise generated by airflow through the gaps. On the other hand, they effectively buffer the mechanical vibrations caused by the operation of the centrifugal fan, blocking the transmission and diffusion of vibration noise through the rigid plate splicing joints. Combined with the original noise reduction components, they form a triple noise reduction barrier of sound absorption, vibration damping, and sealing, which has a more prominent quieting effect than ordinary hard sealing elements, significantly weakening the noise of motor operation and airflow turbulence.

[0035] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air guide plate 3 includes an air guide main plate 31 and connecting foam 32. The air guide main plate 31 is disposed on the housing assembly 1 and located on the inner side wall of the housing assembly 1. There are multiple connecting foams 32, which are sandwiched between the air guide main plate 31 and the housing assembly 1. The fan assembly 4 is disposed on the air guide main plate 31. By utilizing the connecting foam 32, which is a flexible buffer material, it can effectively block the mechanical vibration generated by the operation of the fan assembly 4, preventing the vibration from being directly transmitted to the housing assembly 1 and causing resonance noise in the housing. It weakens the noise transmission from the source of vibration. Together with the foam seal and noise reduction component 5 of the fan part, it forms a full-link sound absorption and vibration reduction barrier, greatly reducing the overall operating noise of the machine and creating a quieter wine storage environment. On the other hand, multiple sets of connecting foam 32 tightly fill the assembly gap between the air guide main board 31 and the box assembly 1, achieving full sealing of the air duct edge, preventing airflow in the condensation space 102 from leaking out from the side gap, ensuring stable closed-loop airflow with air outlet on the upper side and return air on the lower side, avoiding air volume loss, and improving the uniformity of cooling heat exchange and temperature control.

[0036] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air guide plate 3 also includes decorative covers 33, and there are multiple decorative covers 33, which are placed at the connection between the air guide main plate 31 and the box assembly 1. By completely covering the splicing gap between the air guide main plate 31 and the box assembly 1 with multiple sets of decorative covers 33, the internal splicing marks are completely eliminated, making the inner sidewall of the box assembly 1 smoother and simpler overall, without exposed gaps, connectors or assembly defects, maintaining a neat and uniform visual effect inside the box, maximizing the display attributes of the product's high-end and exquisite nature, and without compromising the aesthetics of the wine storage space.

[0037] like Figure 4 , Figure 5 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air duct structure 100 also includes a liquid receiving shell 7, which is disposed on the cabinet assembly 1 and opposite to the evaporator 5; the air guide plate 3 also includes a guide plate 34, which is disposed on the main air guide plate 31 and extends towards the liquid receiving shell 7. By providing a liquid receiving shell 7 opposite to the evaporator 5, and in conjunction with the guide plate 34 extending towards the liquid receiving shell on the main air guide plate 31, the problem of condensate accumulation and leakage during the cooling process of the wine cabinet evaporator 5 is specifically solved. The condensate generated by the evaporator 5 can be smoothly guided along the directional extension slope of the guide plate 34 to the corresponding liquid receiving shell 7, preventing condensate from dripping randomly and eliminating the problems of component corrosion and mold growth caused by water accumulation. At the same time, it prevents water from seeping into the air duct gaps and damaging the foam sealing and noise reduction structure, ensuring the long-term sealing and noise reduction effect of the air duct. The liquid receiving housing 7 centrally collects condensate, preventing it from dripping onto internal electrical components and ensuring the normal operation of the wine cabinet.

[0038] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the air duct structure 100 also includes a temperature detection element 8, which is disposed on the air guide plate 3 and is used to detect the temperature of the storage space 1011. By directly installing the temperature detection element 8 on the air guide plate 3, close to the core temperature sensing area of ​​the storage space 1011, and avoiding local temperature interference from heat exchange and air supply components such as the evaporator 5 and the fan assembly 4, the true and stable real-time temperature inside the box can be accurately collected, eliminating the problem of temperature measurement deviation. Combined with the dual-temperature zone independent air duct design, independent temperature measurement and individual temperature adjustment can be achieved for each storage space, fundamentally avoiding the drawbacks of temperature cross-contamination between upper and lower temperature zones and temperature control lag, ensuring that the temperature and humidity of each storage area are constant and meet the standards, and adapting to the differentiated storage temperature requirements of different wines such as red wine and white wine. At the same time, real-time accurate temperature measurement can link the intelligent start and stop of the fan and refrigeration system, avoiding continuous high-load operation, reducing unnecessary energy consumption, and taking into account both energy saving and temperature control stability.

[0039] 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.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. 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.
