Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0034] Please see Figure 1 , Figure 2 and Figure 6This application provides a sterilization and deodorization device 100, including a photocatalytic module 20, a light converging element 31, and a light source 32. The light converging element 31 is disposed between the photocatalytic module 20 and the light source 32. The light emitted by the light source 32 is converged after passing through the light converging element 31, and the converged light irradiates the photocatalytic module 20.

[0035] For example, the light source 32 can be a lamp bead or a lamp tube, and the light emitted by the light source 32 is ultraviolet light. For example, the wavelength of the ultraviolet light is 100-400nm, such as 254nm.

[0036] For example, the number of light sources 32 can be one or more. When the number of light sources 32 is multiple, the multiple light sources 32 can be arranged in a row, a column or an array.

[0037] For example, the photocatalytic module 20 is made of carbon nanotube-doped molecular sieve catalyst. For example, the molecular sieve catalyst comprises a multi-metal combination, mainly composed of manganese copper oxide (Mn-Cu) and platinum (Pt), with added cerium oxide (Ce), silver (Ag), and TiO2 as the substrate. Simultaneously, the molecular sieve catalyst has dual supports, using cordierite ceramic and silica-alumina molecular sieves as supports. The molecular sieve and ceramic serve as dual supports for the active metals, enhancing the physical bonding and dispersion of the catalyst and increasing the reaction rate. The carbon nanotubes can be considered as graphene sheets rolled up. The p electrons of the carbon atoms on the carbon nanotubes form a large-scale delocalized π bond, exhibiting a significant conjugation effect, giving the carbon nanotubes excellent electronic conductivity. This significantly enhances the oxidation activity of the catalyst under photo-electric effects. Furthermore, due to the barrel-shaped structure of the carbon nanotubes, compared to sheet-like graphene, it is more conducive to the diffusion and adsorption / desorption of odor gas molecules.

[0038] In other embodiments, the material of the photocatalytic module 20 can be carbon-based material, porous mineral material, polymer composite material or nanocatalytic material, etc., wherein the carbon-based material can be activated carbon, the porous mineral material can be maifanite, and the polymer composite material can be plant fiber composite material.

[0039] The sterilization and deodorization device 100 provided in this application embodiment has a photocatalytic module 20 that can generate strong oxidation-reduction capabilities under light conditions. Through a series of chemical reactions, it decomposes and destroys bacteria, viruses, and odor molecules, thereby achieving the effect of sterilization and deodorization. The light converging element 31 can converge the light emitted by the light source 32 and make the converged light irradiate the photocatalytic module 20, thereby improving the photocatalytic efficiency and thus improving the sterilization and deodorization effect. When the sterilization and deodorization device 100 is applied in the storage room of refrigeration equipment, it can reduce the generation of odors and inhibit the growth of microorganisms, thereby improving the user experience and enhancing food safety.

[0040] For example, the light converging element 31 includes one or more combinations of Fresnel lenses, biconvex lenses, plano-convex lenses, and concave-convex lenses. It is understood that "multiple" refers to two or more types of lenses, and when the light converging element 31 includes a combination of multiple lenses, the optical axes of the multiple lenses are located on the same straight line.

[0041] A Fresnel lens is a thin lens that achieves optical focusing through a stepped surface design. Its core principle is to "compress" the continuous curved surface of a traditional lens into a concentric ring prism structure, significantly reducing thickness and weight while maintaining optical performance. Please refer to [link / reference]. Figure 5 In some embodiments, the light converging element 31 is a Fresnel lens. The Fresnel lens can convert light rays from multiple different angles into parallel emitted light rays. The parallel emitted light rays can be perpendicularly irradiated onto the photocatalytic module 20, thereby achieving a high light utilization rate and thus a high sterilization and deodorization efficiency.

[0042] It is understandable that the biconvex lens, plano-convex lens, and concave-convex lens are all converging lenses with light-convexity function. The diverging light emitted from the light source 32 is converted into converging light after entering the biconvex lens / plano-convex lens / concave-convex lens and then emitted. The converging light shines on the photocatalytic module 20, which can achieve a high light utilization rate and thus a high sterilization and deodorization efficiency.

[0043] Please see Figures 1 to 4 Or, see Figures 6 to 7 The sterilization and deodorization device 100 also includes a housing 40, and the photocatalytic module 20, the light converging element 31 and the light source 32 are each disposed inside the housing 40 and / or connected to the housing 40.

[0044] Please see Figure 2 and Figure 5 Or, see Figure 6 and Figure 8 The housing 40 is provided with a groove 401, the light source 32 is installed in the groove 401, and the inner wall of the groove 401 is provided with a reflective film layer 61.

[0045] For example, the reflective film layer 61 has a reflectivity of 80% or greater to ultraviolet light.

[0046] It is understandable that the reflective film layer 61 on the inner wall of the groove 401 can reflect the light that shines on the inner wall of the groove 401, causing this part of the light to change direction and finally be emitted from the outlet of the groove 401. That is to say, by setting the reflective film layer 61 in the groove 401, the light emission rate can be increased, and more light can reach the photocatalytic module 20 to trigger the photocatalytic reaction, thereby improving the photocatalytic efficiency and thus improving the sterilization and deodorization effect.

[0047] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the inner wall of the groove 401 is a curved surface, such as a parabola, a spherical surface, or an ellipsoidal surface.

[0048] For example, when the inner wall of the groove 401 is curved, the housing 40 is provided with a plurality of grooves 401 arranged in parallel, and the light source 32 is installed in each groove 401.

[0049] Please see Figure 4 The cross-sectional area of ​​the groove 401 gradually increases in the direction from the bottom of the groove to the opening.

[0050] It should be noted that the cross-section of the groove 401 refers to the closed area formed by the intersection of an imaginary cutting plane perpendicular to the extension direction (or axis) of the groove 401 and the inner wall of the groove 401, and the cross-sectional area of ​​the groove 401 refers to the area of ​​the closed area.

[0051] It is understandable that by setting the cross-sectional area of ​​the groove 401 to gradually increase in the direction from the bottom of the groove 401 to the opening, the groove 401 can have a larger opening, thereby allowing more light to be emitted and improving the light utilization rate.

[0052] Please see Figure 2 and Figure 3 The opening and cross-section of the groove 401 are elliptical or circular. It can be understood that by setting the opening and cross-section of the groove 401 to be elliptical or circular, the inner wall of the groove 401 can be made smoother, thereby improving the light reflectivity of the inner wall and thus improving the light emission rate.

[0053] Please see Figure 4 The longitudinal section of the groove 401 is a portion of a circle or an ellipse. For example, the longitudinal section of the groove 401 is an axisymmetric figure.

[0054] It should be noted that the longitudinal section of the groove 401 refers to the cross-sectional profile formed by the intersection of an imaginary cutting plane along the extension direction (or axis) of the groove 401 and the inner wall of the groove 401. The longitudinal section is parallel to the length direction of the groove 401.

[0055] It is understandable that by setting the longitudinal section of the groove 401 to a part of a circle or ellipse, the angle of the tangent at different points on the inner wall of the groove 401 in the direction from the bottom of the groove 401 to the opening is different, thereby achieving different reflection effects, so that the light emitted from the groove 401 has a variety of different emission angles, thus achieving a more uniform light emission effect.

[0056] Please see Figure 6 and Figure 7 In some other embodiments, the inner wall of the groove 401 includes a side wall and a bottom, and a prism structure 62 is provided on the bottom of the groove, and the reflective film layer 61 is disposed on the surface of the prism structure 62.

[0057] Please see Figure 6 For example, when the bottom of the groove 401 is provided with a prism structure 62, a groove 401 can be provided on the housing 40, and a plurality of light sources 32 are arranged in parallel in the groove 401.

[0058] For example, when a prism structure 62 is provided on the bottom surface of the groove 401, the prism structure 62 includes and is provided with a plurality of prisms, which are arranged sequentially on the bottom surface of the groove 401. The prisms can be triangular prisms, quadrangular prisms, pentagonal prisms, etc.

[0059] In some embodiments, the prism is a triangular prism with a triangular cross-section, and one vertex of the triangle is oriented toward the inner cavity of the groove 401.

[0060] For example, when a prism structure 62 is provided on the bottom surface of the groove 401, the bottom of the groove 401 can be planar, and the groove 401 can be cuboid or cube-shaped.

[0061] For example, the reflective film layer 61 includes a reflective layer, a protective layer and a self-cleaning coating stacked in sequence, wherein the reflective layer is disposed in conform to the inner wall of the groove 401.

[0062] For example, the reflective layer has a reflectivity of 90% or greater for ultraviolet light.

[0063] For example, the material of the reflective layer includes metals, such as aluminum. It is understood that metals have a high reflectivity, thus providing a better reflective effect.

[0064] It should be noted that the protective layer can protect the reflective layer while having a high ultraviolet transmittance (over 90%), meaning that the protective layer will not affect the reflective performance of the reflective film layer 61. For example, the material of the protective layer includes silicon dioxide.

[0065] It should be noted that the self-cleaning layer is located on the outermost layer of the reflective film layer 61, and it can directly contact environmental pollutants. The self-cleaning layer has hydrophobic properties, which can prevent water stains and dust from adhering, thus maintaining the surface cleanliness of the reflective film layer 61 and achieving a maximum self-cleaning effect. Furthermore, the self-cleaning coating has a high ultraviolet transmittance (over 90%), so it will not affect the reflective performance of the reflective film layer 61. For example, the material of the self-cleaning coating includes fluorosilane.

[0066] For example, a dielectric film may be disposed between the reflective layer and the protective layer to further enhance the reflectivity of the reflective film layer 61. The material of the dielectric film is an optically transparent medium, such as silicon dioxide, magnesium fluoride, barium titanate, etc.

[0067] Please see Figure 1 , Figure 2 and Figure 6 The housing 40 is provided with an air inlet 71 and an air outlet 72. The photocatalytic module 20 is disposed inside the housing 40. The photocatalytic module 20 is disposed between the air inlet 71 and the air outlet 72 in the gas flow path. The photocatalytic module 20 is provided with multiple hollow parts 21. The housing 40 is also provided with a fan 51, which is disposed close to the air outlet 72.

[0068] It is understandable that by setting an air inlet 71 and an air outlet 72 on the housing 40, and installing a fan 51 inside the housing 40, with the fan 51 positioned close to the air outlet 72, the exhaust effect of the fan 51 can be used to promote the exchange of air inside the sterilization and deodorization device 100 with the air in the external environment (such as the storage room of a refrigeration unit), bringing the active substances generated by photocatalysis to the external environment, thereby expanding the range of action of the active substances and achieving a better sterilization and deodorization effect on the external environment.

[0069] Please see Figure 1 The sterilization and deodorization device 100 also includes an ion catalysis module 52, which is installed on the housing 40 and located at the air outlet 72.

[0070] It should be noted that the ion catalysis module 52 can generate a large number of ions (such as positive ions and negative ions) and active particles (such as oxygen ions and hydroxyl radicals) through high-voltage discharge or corona discharge. These particles have high reactivity and can undergo forced oxidation-reduction reactions with microorganisms and organic pollutants in the air, destroying their molecular structure and thus achieving sterilization and deodorization effects. In this embodiment, by placing the ion catalysis module 52 at the air outlet 72, the active substances generated by ion catalysis can be carried to the external environment (such as the storage compartment of a refrigeration unit) by the flow of air, thereby expanding the range of action of the active substances and achieving better sterilization and deodorization effects on the external environment.

[0071] Please see Figure 1 The ion catalysis module 52 includes a discharge electrode 521, and the surface of the discharge electrode 521 is provided with a catalytic coating.

[0072] It should be noted that when a high voltage is applied to the discharge electrode 521, a high-voltage electric field is formed near the discharge electrode 521. This high-voltage electric field can interact with water molecules and oxygen molecules in the air to form and release a series of active particles, such as electrons, positive ions, negative ions, hydrated ions, active oxygen, and active nitrogen, thereby achieving sterilization and deodorization effects. Furthermore, by providing a catalytic coating on the surface of the discharge electrode 521, an ion catalytic reaction can be triggered in the catalytic coating simultaneously with the generation of ions by the discharge electrode 521, further enhancing the sterilization and deodorization effects. For example, the catalytic coating may include TiO2-based noble metal materials, ZnO / Al2O3 / SiO2, etc.

[0073] For example, the ion catalysis module 52 also includes a counter electrode.

[0074] For example, the discharge mode of the ion catalysis module 52 can be needle tip discharge, needle plate discharge or carbon brush discharge.

[0075] When the discharge mode of the ion catalysis module 52 is needle tip discharge, the discharge electrode 521 is a single needle-shaped electrode (or a small number of isolated needle-shaped electrodes), and the counter electrode is a flat plate electrode or a curved electrode. The curvature of the needle-shaped electrode is extremely large, and it is concentrated in a "point" shape.

[0076] When the discharge mode of the ion catalysis module 52 is needle-plate discharge, the discharge electrode 521 includes multiple needle-shaped electrodes (needle-shaped electrodes arranged in an array, or needle-shaped electrodes arranged in multiple rows or columns), and the counter electrode is a flat electrode or a curved electrode, with the needle tips arranged in an orderly manner to form a "multiple needle tips → flat plate" layout.

[0077] When the discharge mode of the ion catalysis module 52 is carbon brush discharge, the discharge electrode 521 includes multiple densely arranged brush-shaped fine conductors (carbon wires / metal wires), and the counter electrode is a flat plate electrode or a cylindrical electrode, with a "volume / surface" distributed structure and no obvious sharp single point.

[0078] Please see Figures 1 to 4 as well as Figures 6 to 7 The housing 40 includes a top plate 41, a bottom plate 42, a transverse partition 45, a first side plate 43, and a second side plate 44. The transverse partition 45 is disposed between the top plate 41 and the bottom plate 42. One end of the first side plate 43 is connected to the top plate 41, and the other end is connected to the bottom plate 42. The periphery of the transverse partition 45 is connected to the first side plate 43. The second side plate 44 is disposed between the top plate 41 and the transverse partition 45 and is disposed inside the first side plate 43. Both ends of the second side plate 44 are respectively connected to the top plate 41 and the transverse partition 45. The top plate 41, the transverse partition 45, and the second side plate 44 together enclose a fan chamber 403. The fan 51 is located in the fan chamber 403. The transverse partition 45 is provided with an air inlet 451, which is provided on the air inlet side of the fan 51.

[0079] For example, the first side panel 43 may include one or more connected side panels, and the second side panel 44 may include one or more connected side panels.

[0080] For example, the first side plate 43 is in a closed loop shape.

[0081] Please see Figures 1 to 4 as well as Figures 6 to 7 The photocatalytic module 20 is disposed on the inner side of the first side plate 43.

[0082] For example, the photocatalytic module 20 is connected to at least one of the first side plate 43, the second side plate 44, the top plate 41, and the bottom plate 42.

[0083] For example, at least one of the first side plate 43, the top plate 41, and the bottom plate 42 is connected to the light converging element 31.

[0084] Please see Figure 1 For example, the ion catalysis module 52 is mounted on the diaphragm 45, and the fan 51 is mounted on the top plate 41.

[0085] Please see Figures 2 to 4 as well as Figures 6 to 7For example, the housing 40 further includes a power module 63, and the discharge electrodes 521 of the light source 32 and the ion catalysis module 52 are both connected to the power module 63. In some embodiments, the power module 63 is disposed inside the housing 40 and on the inner side of the first side plate 43. For example, the groove 401 is disposed on the power module 63.

[0086] It is understood that the power module 63 can provide power to the light source 32 and the discharge electrode 521 of the ion catalysis module 52.

[0087] Please see Figures 2 to 4 as well as Figures 6 to 7 For example, the light source 32 can be mounted on the power module 63.

[0088] For example, at least one of the top plate 41, the bottom plate 42, and the first side plate 43 is connected to the power module 63.

[0089] This application embodiment also provides a refrigeration device, including the sterilization and deodorization device 100 as described above.

[0090] For example, the refrigeration equipment can be a refrigerator, freezer, beverage cooler, wine cooler, freezer box, ice cream machine, ice maker, etc.

[0091] For example, the refrigeration equipment includes a cabinet 40, a storage room is provided inside the cabinet 40, and the sterilization and deodorization device 100 is provided inside the storage room.

[0092] For example, the storage room includes a refrigerator compartment and a freezer compartment, the refrigerator compartment is provided with the sterilization and deodorization device 100, and / or the freezer compartment is provided with the sterilization and deodorization device 100.

[0093] For example, the temperature of the refrigerator compartment is 2℃ to 8℃, such as 2℃, 3℃, 4℃, 5℃, 6℃, 7℃, 8℃, etc.

[0094] For example, the temperature of the freezer compartment is -18℃ to -25℃, such as -18℃, -19℃, -20℃, -21℃, -22℃, -23℃, -24℃, -25℃, etc.
