[0046] like Figure 1-Figure 8 As shown, an embodiment of the present application provides an ion sterilization device for providing negative ions into a compartment 71, and an air duct mask 1 is provided on the rear wall of the compartment 71; the ion sterilization device is connected to the air duct mask 1, and the ion sterilization device includes: a shell 2, an ion generating assembly 3 and a fan assembly 4.

[0047] The shell 2 has a cavity 21 and an air inlet 22 and an air outlet 23 connected to the cavity 21. The shell 2 includes a first part located in the compartment 71 and a second part located on the side of the air duct mask 1 away from the compartment 71. The air inlet 22 and the air outlet 23 are arranged in the first part.

[0048] The ion generating assembly 3 is disposed in the cavity 21 and is used for generating negative ions.

[0049] The fan assembly 4 is disposed in the cavity 21 and is used to drive the gas in the compartment 71 to enter the cavity 21 through the air inlet 22 and be sent out through the air outlet 23 .

[0050] In the present application, by hiding the second part of the shell 2 to the side of the air duct mask 1 away from the compartment 71, the space inside the compartment 71 is no longer occupied, the utilization rate of the storage space inside the refrigerator is improved, the structure is compact, and it is easy to install and maintain; by arranging both the air inlet 22 and the air outlet 23 in the first part, the gas squeezed in the compartment 71 can enter the cavity 21 of the shell 2 through the air inlet 22 driven by the fan assembly 4, and the negative ions generated by the ion generating assembly 3 are sent out through the air outlet 23, so that the interior of the compartment 71 is sterilized and deodorized, thereby realizing efficient circulation and distribution of negative ions.

[0051] In the related art, the current ion sterilization devices are mostly arranged on the top of the refrigerating compartment 71, adopting a protruding design, which occupies a large space in both the thickness direction and the width direction, and occupies a large space inside the refrigerating compartment 71, affecting the utilization rate of the storage space inside the refrigerator.

[0052] In the embodiment of the present application, the second part of the housing 2 is hidden behind the air duct mask 1, which solves the problem of the traditional protruding design occupying the storage space and improves the utilization rate of the refrigerator storage space. The coordinated work of the ion generating assembly 3 and the fan assembly 4 ensures the effective diffusion of negative ions, and the reasonable arrangement of the air inlet 22 and the air outlet 23 ensures the air circulation effect, meeting the market demand for sterilization and deodorization functions.

[0053] Specifically, the fan assembly 4 can be an axial flow fan or a centrifugal fan; the housing 2 can be made of different materials (such as ABS, PP, etc.) to meet different cost requirements.

[0054] In some embodiments, the ion sterilization device is disposed on the top of the air duct mask 1 and extends along the width direction of the compartment 71 .

[0055] In the present application, by setting the ion sterilization device at the top of the air duct mask 1, the ion sterilization device is just located at the corner behind the top of the compartment 71, which can further reduce the occupation of the internal space of the compartment 71 by the ion sterilization device. The ion sterilization device extends in the width direction to form a linear arrangement. The top installation position facilitates the downward diffusion of negative ions, and cooperates with the fan assembly 4 to achieve a better circulation effect. By extending the ion sterilization device in the width direction, a larger area of ​​negative ion coverage is achieved. The design located at the top utilizes the natural law of hot air rising and improves the uniformity of negative ion distribution.

[0056] In some embodiments, the air inlet direction of the air inlet 22 and the air outlet direction of the air outlet 23 are arranged to intersect.

[0057] In the related art, the current ion sterilization device generally adopts the form of left and right air intake and rearward air outlet, and the air inlet 22 and the air outlet 23 are located in the same plane, which occupies a large space.

[0058] In the present application, the air inlet direction and the air outlet direction are arranged to intersect each other, so that the air inlet 22 and the air outlet 23 are not located in the same plane, thereby saving structural space.

[0059] Specifically, the air inlet 22 is located at the bottom of the shell 2, and the air outlet 23 is located at the front side of the shell 2. The gas in the chamber 71 enters the cavity 21 through the air inlet 22, and then flows in the cavity 21. After carrying the generated negative ions, it is sent to the chamber 71 through the air outlet 23 on the front side, and the interior of the chamber 71 is sterilized and purified by the gas carrying negative ions.

[0060] Moreover, the angle design of the air inlet and outlet 23 forms an air flow intersection, and the vortex generated by the intersection of the air flow promotes the diffusion of negative ions, and the intersection of the air flow can increase the contact time between air and negative ions. The intersecting air flow direction design forms an eddy effect, which enhances the air circulation effect in the compartment 71, improves the dispersion and coverage of negative ions, and reduces air flow dead angles.

[0061] In some embodiments, an air inlet space 211, an air supply space 212 and an air outlet space 213 are provided in the cavity 21. The air supply space 212 is connected to the air inlet space 211 through a first connecting hole, and the air outlet space 213 is connected to the air supply space 212 through a second connecting hole. The air inlet 22 is connected to the air inlet space 211, and the air outlet 23 is connected to the air outlet space 213. The fan assembly 4 is provided in the air supply space 212, and is used to drive the gas in the air inlet space 211 into the air outlet space 213.

[0062] In the present application, the airflow channel is controlled by the first connecting hole and the second connecting hole, and the arrangement of the fan assembly 4 in the air supply space 212 optimizes the airflow organization, and the series design of the three spaces forms a complete airflow channel. The orderly flow of airflow is achieved through the three-stage space design, which reduces airflow noise, improves air processing efficiency, and facilitates the reasonable arrangement of various functional components.

[0063] Specifically, the gas in the compartment 71 enters the air intake space through the air inlet 22, and then enters the air supply space 212 through the first connecting hole. At this time, the gas moves backward to the second part of the shell 2, utilizes the second part of the shell 2, and then enters the air outlet space 213 through the second connecting hole, and finally is discharged through the air outlet 23. The problem of chaotic airflow in the traditional single-cavity design is solved, and a better component installation space is provided, which is conducive to the precise control of airflow. Compared with the traditional single-space design, the partition design is more conducive to airflow organization and function realization.

[0064] Optionally, connecting holes of different shapes and sizes may be designed, and the layout may be optimized by adjusting the relative positions of the three spaces.

[0065] In some embodiments, the ion generating assembly 3 includes an ion generator 31 and a discharge member 32 electrically connected to the ion generator 31 . The discharge member 32 is located in the air outlet space 213 . The ion generating assembly 3 forms negative ions at the discharge member 32 .

[0066] In the present application, the ion generator 31 provides a high voltage power supply, and the discharge element 32 generates negative ions in the air outlet space 213, and the negative ions are directly output into the compartment 71 along with the air flow. The discharge element 32 is located in the air outlet space 213, ensuring that the negative ions can be directly output along with the air flow, reducing the loss of negative ions during the transmission process, improving the concentration and utilization rate of negative ions, and avoiding the interference of discharge with other components.

[0067] Specifically, the discharge element 32 is arranged in the air outlet space 213 because the negative ions generated in the air will decrease over time. In order to improve the sterilization effect, the present application arranges the discharge element 32 in the air outlet space 213, adjacent to the air outlet 23, so that the newly generated negative ions are sent into the compartment 71 with the air flow for sterilization, thus solving the problem of the easy attenuation of traditional negative ions, improving the sterilization and deodorization efficiency, and reducing energy consumption.

[0068] In some embodiments, the discharge member 32 includes at least one of a carbon brush and a needle electrode.

[0069] In this application, carbon brushes and needle electrodes are both mature and reliable discharge elements, which can be flexibly selected or used in combination according to needs. The optimal solution can be selected for different usage environments, and maintenance and replacement are convenient.

[0070] Specifically, carbon brush discharge: large contact area, stable discharge, long life, low maintenance cost, suitable for large-area discharge needs. Needle electrode discharge: concentrated electric field, high discharge efficiency, simple structure, low cost, suitable for precise control occasions.

[0071] Optionally, a combination design of carbon brushes and needle-shaped electrodes may be adopted, and different numbers of discharge units may be selected according to actual needs.

[0072] Among them, the carbon brush is a brush-shaped discharge element made of carbon material; the needle electrode is a metal electrode with a tip discharge. According to experimental tests, the distance d between the carbon brushes will affect the concentration of negative ions generated. When the horizontal distance is in the range of 18-20mm, the negative ion concentration is the highest; in addition, negative ions generally have a short survival time in the air. Therefore, by placing the negative ion generator behind the air outlet, the negative ions generated can be quickly and directly blown to the cold storage room, reducing the occurrence of premature inactivation of negative ions due to too long air path, and improving the sterilization efficiency and effect.

[0073] In the related technology, all refrigerator brands on the market basically have sterilization and odor removal functions, but most products discharge through the tip of a high-voltage needle electrode to generate charged negative ions, which adsorb dust in the air to achieve the effect of purifying the air and preserving freshness; but the negative ions generally generated in this way often form harmful substances such as ozone in the process, and ozone will affect the health of users; another method of generating negative ions through discharge of a brush-shaped negative ion generator 31 can solve this problem. In the process of generating negative ions through discharge of the brush-shaped negative ion generator 31, the ozone concentration can be controlled at a low level, but because the brush-shaped negative ion generator 31 occupies a large space.

[0074] Preferably, the ion generating assembly 3 in the present application adopts a carbon brush ion generator 31, which can effectively control the ozone concentration, and by hiding a part of the shell 2, the problem of occupying a large space is solved at the same time.

[0075] In some embodiments, the ion sterilization device further includes a filter element 5 disposed between the air inlet space 211 and the air supply space 212 , and the filter element 5 is used to filter the gas entering the air supply space 212 from the air inlet space 211 .

[0076] In the present application, a filter 5 is arranged in the air flow channel to intercept particulate matter in the air through the filter material, and work in conjunction with the negative ion generating device to filter dust and impurities in the air, protect the internal components from pollution, improve the air purification effect, and extend the service life of the device.

[0077] Specifically, it solves the air quality problem in the refrigerator, reduces odor, and reduces maintenance frequency. It combines the filtering function with negative ion sterilization to form a multiple purification effect.

[0078] Optionally, a multi-layer filter structure may be used, and filter materials of different materials (such as activated carbon, HEPA, etc.) may be used.

[0079] In a specific embodiment, the filter element 5 in the present application adopts a deodorizing block to circulate and deodorize the gas in the compartment 71 .

[0080] In some embodiments, the ion sterilization device further includes a spacing component 6 connected to the housing 2 , and the air inlet 22 and the air outlet 23 are respectively located on two sides of the spacing component 6 .

[0081] In the present application, the spacer assembly 6 forms a physical partition, optimizes the airflow by rationally designing the partition structure, and provides independent installation space for each functional component. The spacer assembly 6 realizes effective separation of space, optimizes the guidance of the airflow path, reduces airflow crosstalk, and improves space utilization efficiency.

[0082] Specifically, it solves the problem of chaotic spatial layout, improves airflow organization efficiency, and facilitates the installation and positioning of various functional components. Compared with the traditional overall cavity 21 design, the partitioned layout is more conducive to function realization and efficiency improvement.

[0083] In some embodiments, the spacer assembly 6 includes: a transparent decorative plate 61 detachably connected to the housing 2 ; and a light bar 62 disposed between the transparent decorative plate 61 and the housing 2 .

[0084] In the present application, a detachable transparent decorative panel 61 is designed, which is easy to disassemble and has a floating three-dimensional cursor display, thereby enhancing the technological sense of the interior space.

[0085] Specifically, the transparent decorative plate 61 is detachable for easy maintenance, the light bar 62 is arranged inside to provide lighting effects, and the transparent material allows light to pass through. This achieves a perfect combination of beauty and function, provides lighting and indication functions, is easy to maintain and clean, and increases the grade of the product.

[0086] Optionally, transparent plates of different materials may be used, and light strips 62 of different color temperatures may be used.

[0087] In some embodiments, the housing 2 includes a bottom shell 24 and an upper cover 25 , and the upper cover 25 is detachably connected to the bottom shell 24 .

[0088] In this application, a detachable connection method such as a buckle or a screw is adopted, and the upper and lower parts are split into a design and a modular structure, which is convenient for assembly and maintenance, reduces production costs, and improves maintenance efficiency.

[0089] Specifically, the upper cover 25 and the bottom shell 24 are detachably connected by snap-fitting, so that the filter element 5 inside the shell 2 can be easily replaced.

[0090] An ion sterilization device provided in an embodiment of the present application hides the second part of the shell 2 to the side of the air duct mask 1 away from the compartment 71, so that the space inside the compartment 71 is no longer occupied, thereby improving the utilization rate of the storage space inside the refrigerator, and having a compact structure and being easy to install and maintain; by arranging both the air inlet 22 and the air outlet 23 in the first part, the gas squeezed in the compartment 71 can enter the cavity 21 of the shell 2 through the air inlet 22 driven by the fan assembly 4, and the negative ions generated by the ion generating assembly 3 are sent out through the air outlet 23, so as to sterilize and deodorize the interior of the compartment 71, thereby realizing efficient circulation and distribution of negative ions.

[0091] In the related art, the current ion sterilization devices are mostly arranged on the top of the refrigerating compartment 71, adopting a protruding design, which occupies a large space in both the thickness direction and the width direction, and occupies a large space inside the refrigerating compartment 71, affecting the utilization rate of the storage space inside the refrigerator.

[0092] In the embodiment of the present application, the second part of the housing 2 is hidden behind the air duct mask 1, which solves the problem of the traditional protruding design occupying the storage space and improves the utilization rate of the refrigerator storage space. The coordinated work of the ion generating assembly 3 and the fan assembly 4 ensures the effective diffusion of negative ions, and the reasonable arrangement of the air inlet 22 and the air outlet 23 ensures the air circulation effect, meeting the market demand for sterilization and deodorization functions.
