[0038] Combination Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application provides a sterilization and deodorization device 10, comprising:

[0039] The housing 300 has an airflow channel S1; the airflow channel S1 is connected to the external environment.

[0040] A light source 100 is disposed within the airflow channel S1;

[0041] A reflective structure 200 is disposed in the airflow channel S1 and is positioned opposite to the light source 100. It is used to reflect the light emitted by the light source 100 back to the light source 100 so as to form a sterilization light curtain in the airflow channel S1.

[0042] In the technical solution of this application embodiment, the light source 100 and the reflective structure 200 are both disposed within the airflow channel S1 and are arranged opposite to each other. The light emitted by the light source 100 is directed towards the reflective structure 200, and the reflective structure 200 reflects the light back to the light source 100, thus forming a sterilization light curtain within the airflow channel, improving the utilization rate of light and thereby improving sterilization efficiency. When the gas in the external environment passes through the airflow channel S1, the microorganisms in the gas are disinfected under the action of the sterilization light curtain, achieving the purpose of sterilization and deodorization.

[0043] In some embodiments, the light source 100 may include a plurality of spaced-apart LEDs or a lamp tube. In some embodiments, to improve the sterilization effect, the light source 100 uses ultraviolet light with a typical wavelength of 254 nm. Ultraviolet light has a good sterilization effect. Furthermore, the parallel ultraviolet light beams form an ultraviolet light curtain, which significantly improves the sterilization effect. The light source 100 may use other ultraviolet bands such as 100-400 nm, including UVA / UVB / UVC.

[0044] In some embodiments, the light source 100 and the reflective structure 200 can be arranged vertically, horizontally, or front-to-back. In some embodiments, the relative directions of the light source 100 and the reflective structure 200 are perpendicular to the direction of the gas in the airflow channel; for example, if the gas direction is vertical, then the light source 100 and the reflective structure 200 are arranged front-to-back or horizontally.

[0045] In this embodiment, the light source 100 and the reflective structure 200 can be connected and fixed to the housing 300 by threaded parts, snap fasteners, adhesive parts, etc.

[0046] In an embodiment, the sterilization and deodorization device 10 further includes a power supply 700 or an energy conversion device (not illustrated). The power supply 700 is configured to provide electrical energy to the light source 100; or the energy conversion device is configured to convert the electrical energy from the external power supply 700 into electrical energy usable by the light source 100.

[0047] In this embodiment, the reflective structure 200 includes a first reflective surface for reflecting light. From the inside out, the first reflective surface is provided with a reflective layer, a protective layer, and a cleaning layer. The reflective layer, protective layer, and cleaning layer are, respectively, a reflective coating, a protective coating, and a cleaning coating. The reflective coating is selected based on the emission wavelength of the light source 100. For example, if the light source 100 emits ultraviolet light with a wavelength of 254nm, an aluminum (or aluminum alloy) coating is selected for the reflective coating to improve reflectivity. The protective coating is used to prevent the reflective coating from aging due to light. For example, a silicon oxide coating, such as silicon dioxide (SiO2), can be selected, which has high ultraviolet transmittance and does not affect the reflective properties of the reflective coating, while protecting the reflective structure 200 from ultraviolet aging. The preferred cleaning coating is a transparent TiO2 coating, which can trigger a photocatalytic reaction under ultraviolet light, thereby generating free electrons and holes for sterilization and deodorization. In addition, TiO2 has self-cleaning properties. Its self-cleaning principle is based on hydrophilicity. When water droplets fall on the surface, they will quickly spread into a thin film instead of forming water droplets. When dust, oil, etc. adhere to the TiO2 coating surface, the water film will carry away these contaminants, and the surface will be cleaned.

[0048] As an optional implementation of the above embodiments, the reflective structure 200 includes a reflective prism; the reflective prism is disposed on the wall surface 330 of the housing 300. In some embodiments, the reflective prism can be adhered to the wall surface 330. In some embodiments, the reflective structure 200 includes a wall surface, and the reflective prism is fixed to the wall surface, such as by snap-fit ​​or fastening; the wall surface is fixed to the wall surface 330 by threaded parts.

[0049] like Figure 3 As shown, the reflective prism has a first side surface 210 and a second side surface 220; both the first side surface 210 and the second side surface 220 intersect the wall surface 330 on the side towards the light source 100, and the angles formed by the first side surface 210 and the second side surface 220 with the wall surface 330 are equal; both the first side surface 210 and the second side surface 220 extend toward the light source 100 and are arranged to intersect each other.

[0050] In this embodiment, the first side surface 210 and the second side surface 220 are the incident and exit surfaces of the reflective prism, respectively. For example, light enters the reflective prism from the first side surface 210 and exits from the exit surface, and is reflected back to the light source 100 by the reflective prism. Since the angles (α1 and α2) formed by the first side surface 210 and the second side surface 220 with the wall surface 330 are equal, the reflected light and the incident light are basically parallel; thus, the light from the sterilization light curtain is basically uniform within the airflow channel.

[0051] As an optional implementation of the above embodiments, such as Figure 3 As shown, both the first side surface 210 and the second side surface 220 form an angle of 45° with the wall surface 330 and intersect each other perpendicularly. Figure 3 As shown, the cross-section of the prism is an isosceles right triangle, with the hypotenuse located on or parallel to the wall 330. The two right-angled sides are the first side 210 and the side of the prism. This allows light to undergo total internal reflection through the isosceles right-angled triangular prism, further improving light utilization. The two 45° angles of the isosceles right-angled triangle cause the incident light to undergo two total internal reflections inside the prism, ultimately returning along the original path to the source 100.

[0052] As an optional implementation of the above embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, the reflective prism has multiple components, which are arranged sequentially at intervals. In this embodiment, the multiple reflective prisms are arranged sequentially at intervals to increase the reflective coverage area of ​​the reflective structure 200, forming a larger light curtain to improve the sterilization effect.

[0053] As an optional implementation of the above embodiments, such as Figure 3 , Figure 4 As shown, two adjacent reflecting prisms intersect each other on the wall surface 330. (Combined) Figure 2 and 3 As shown, two adjacent reflective prisms intersect each other, meaning that the reflective prisms are continuously arranged on the wall 330, so that almost all the light can be reflected back to the light source 100, thus improving the light utilization rate.

[0054] As an optional implementation of the above embodiments, such as Figure 3 As shown, the light source 100 extends along a preset direction, or the light source 100 includes a plurality of LEDs arranged at intervals along the preset direction; the plurality of reflecting prisms are arranged at intervals along the preset direction. For example, in an embodiment, the light source 100 extends along the width direction, or includes a plurality of LEDs arranged at intervals along the width direction; the plurality of reflecting prisms are arranged at intervals along the width direction. The reflecting prisms can extend along the length direction. With this configuration, the reflecting prisms can reflect almost all the light back to the light source 100, improving light utilization.

[0055] As an optional implementation of the above embodiments, such as Figure 5 As shown, the sterilization and deodorization device 10 further includes a reflective structure 800, which forms a receiving cavity and a light outlet facing the reflective structure 200; the light source 100 is disposed within the receiving cavity; the reflective structure 800 is used to reflect and focus the light emitted by the light source 100 onto the reflective structure 200. In an embodiment, the reflective structure 800 is used to converge the light emitted by the light source 100 in all directions and focus it from the light outlet onto the reflective structure 200, making the light emission directional and improving light utilization. Figure 3 As shown, some light rays are directed toward the reflective structure 800, and after being reflected by the reflective structure 800, they are directed toward the reflective structure 200 through the light outlet. The reflective structure 200 then processes the light rays and directs them toward the light source 100, thereby forming a sterilization light curtain.

[0056] Specifically, the reflective structure 800 has a curved shape, such as an elliptical surface, a parabolic surface, or a hyperboloid. Further, in this embodiment, the light source 100 is located at the focal point of the reflective structure 800, further improving light efficiency. In this embodiment, the reflective structure 800 includes a second reflective surface for reflecting light, on which a reflective layer, a protective layer, and a cleaning layer are sequentially arranged from the inside to the outside. The reflective layer, protective layer, and cleaning layer are, in sequence, a reflective coating, a protective coating, and a cleaning coating. The reflective coating is selected according to the emission wavelength of the light source 100. For example, if the light source 100 emits ultraviolet light with a wavelength of 254nm, an aluminum (or aluminum alloy) coating is selected for the reflective coating to improve reflectivity. The protective coating is used to prevent the reflective coating from aging due to light. For example, a silicon oxide coating, such as silicon dioxide (SiO2), can be selected, which has high ultraviolet transmittance and does not affect the reflective properties of the reflective coating, while protecting the reflective structure 800 from ultraviolet aging. The preferred cleaning coating is a transparent TiO2 coating, which can trigger a photocatalytic reaction under ultraviolet light, thereby generating free electrons and holes for sterilization and deodorization. In addition, TiO2 has self-cleaning properties. Its self-cleaning principle is based on hydrophilicity. When water droplets fall on the surface, they will quickly spread into a thin film instead of forming water droplets. When dust, oil, etc. adhere to the TiO2 coating surface, the water film will carry away these contaminants, and the surface will be cleaned.

[0057] In the embodiment, the reflective structure 800 is disposed on the housing 300, for example, by threaded parts or snap fasteners fixed to the housing 300.

[0058] As an optional implementation of the above embodiments, the housing 300 has an air vent communicating with the airflow channel S1; the air vent is used to connect to the external environment. Figure 1 As shown, the air vent includes an air inlet 310 and an air outlet 320. The air inlet 310 is the vent through which the gas that needs to be sterilized in the external environment enters the housing 300, and the air outlet 320 is the vent through which the gas that has been sterilized and deodorized is discharged to the external environment.

[0059] As shown in Figure 1, the sterilization and deodorization device 10 further includes an electric field sterilization module 500. The electric field sterilization module 500 is located at the air vent and configured to generate a sterilizing electric field to adsorb charged particles in the gas passing through the air vent. In an embodiment, the electric field sterilization module 500 can be located at the air inlet 310 or the air outlet 320; for example, as... Figure 1 As shown, the electric field sterilization module 500 is located at the air inlet 310, and performs electric field sterilization on the incoming air immediately. The charged particles can be charged bacteria and viruses.

[0060] The electric field sterilization module is configured to generate an electric field. When gas flows, charged particles are adsorbed by the electric field as they pass through the module, thus sterilizing and deodorizing the gas. The module includes an air duct for gas to enter or exit the air flow channel S1. In one embodiment, a plate-like hollow microchannel structure, made of materials such as PP or PET, is used. A polymer electrode film with electrode plates is disposed on this structure. The electrodes employ safety barrier technology. The electrode surface has a semiconductor layer to uniformly provide a strong electric field. The strong electric field exerts a strong attraction on charged particles moving in the air, adsorbing these particles, including bacteria and viruses. Microorganisms are continuously inactivated under the continuous strong electric field. In this embodiment, the electric field sterilization module can be fixed to the air vent using a connector. The connector can be a threaded part, a snap-fit ​​part, or other similar connector.

[0061] As shown in Figure 1, in some embodiments, the sterilization and deodorization device 10 further includes an ion catalysis module 600, which is located at the air vent. In embodiments, the electric field sterilization module 500 can be located at the air inlet 310 or the air outlet 320; for example, Figure 1 As shown, the electric field sterilization module 500 is located at the air outlet 320, which sterilizes the gas that is about to be discharged into the external environment again through ion catalytic reaction.

[0062] At the air outlet 320, the ion catalytic component performs one-step ion catalytic treatment on the gas, bringing the active substances generated by ion catalysis into the external environment (such as the storage room of a refrigeration equipment), which can expand the range of action of the active substances and thus achieve a better sterilization and deodorization effect on the external environment.

[0063] Ion catalytic components can generate a large number of ions (such as positive 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 catalytic component at the air outlet 320, the active substances generated by ion catalysis can be carried to the external environment (such as the storage compartment of a refrigerated device) by the flow of air, thereby expanding the effective range of the active substances and achieving better sterilization and deodorization effects on the external environment.

[0064] The ion catalytic assembly includes a discharge electrode. The surface of the discharge electrode is provided with a catalytic coating.

[0065] It should be noted that when a high voltage is applied to the discharge electrode, a high-voltage electric field is formed near the discharge electrode. 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, reactive oxygen species, and reactive nitrogen species, thereby achieving sterilization and deodorization effects. Furthermore, by setting a catalytic coating on the surface of the discharge electrode, an ion catalytic reaction can be triggered by the high-voltage discharge while ions are generated by the discharge electrode, further enhancing the sterilization and deodorization effects. For example, the catalytic coating may include TiO2-based noble metal materials, ZnO / Al2O3 / SiO2, etc.

[0066] In some embodiments, the ion catalysis assembly further includes a counter electrode.

[0067] In some embodiments, the discharge mode of the ion catalytic component can be tip discharge, needle plate discharge, or carbon brush discharge.

[0068] In some embodiments, when the discharge mode of the ion catalytic component is needle tip discharge, the discharge electrode is a single needle electrode (or a small number of isolated needle electrodes), and the counter electrode is a flat plate electrode or a curved electrode. The needle electrodes have extremely high curvature and are concentrated in a "point" shape.

[0069] In some embodiments, when the discharge mode of the ion catalytic component is needle-plate discharge, the discharge electrode 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 plate electrode or a curved surface electrode, with the needle tips arranged in an orderly manner to form a "multiple needle tips → flat plate" layout.

[0070] In some embodiments, when the discharge mode of the ion catalytic component is carbon brush discharge, the discharge electrode 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, exhibiting a "volume / surface" distributed structure without obvious sharp single points.

[0071] In one embodiment, an electric field sterilization module 500 is disposed at the air inlet 310, and an ion catalysis module 600 is disposed at the air outlet 320. In this embodiment, the gas sequentially passes through electric field sterilization, light curtain sterilization, and ion catalysis sterilization.

[0072] In one embodiment, an electric field sterilization module 500 is disposed at the air outlet 320, and an ion catalysis module 600 is disposed at the air inlet 310.

[0073] In one embodiment, the electric field sterilization module 500 is disposed at the air inlet 310. In this embodiment, the gas passes through the electric field sterilization and the light curtain sterilization sequentially.

[0074] In one embodiment, the electric field sterilization module 500 is located at the air outlet 320. In this embodiment, the gas passes through the light curtain for sterilization and then through the electric field for sterilization in sequence.

[0075] In one embodiment, the ion catalysis module 600 is located at the air inlet 310. In this embodiment, the gas sequentially passes through light curtain sterilization and ion catalysis sterilization.

[0076] In one embodiment, the ion catalysis module 600 is located at the air outlet 320. In this embodiment, the gas sequentially passes through ion catalysis sterilization and light curtain sterilization.

[0077] In this embodiment, the power supply 700 of the electric field sterilization module 500 and the ion catalysis module 600 can be the same as the power supply 700 of the light source 100. Alternatively, the electric field sterilization module 500 and the ion catalysis module 600 can be the same as the power conversion device of the light source 100. Of course, the electric field sterilization module 500, the ion catalysis module 600, and the light source 100 can also have different power supplies 700 or different power conversion devices.

[0078] In this embodiment, the power supply 700 or the power conversion device is disposed on the housing 300.

[0079] As an optional implementation of the above embodiments, the sterilization and deodorization device 10 further includes a fan 400, which is disposed within the airflow channel and configured to draw gas from the external environment into the airflow channel S1 and discharge it into the external environment. In this embodiment, the fan 400 is rotatably disposed within the airflow channel; when the fan 400 rotates, it performs work on the gas, drawing gas from the external environment into the airflow channel S1 and discharging it into the external environment. The gas undergoes sterilization and deodorization treatment upon entering the airflow channel, achieving a sterilization and deodorization effect.

[0080] In some embodiments, such as Figure 4 As shown, the airflow channel includes a sterilization air duct S11 and an air duct S12; the sterilization air duct S11 and the air duct S12 are connected through an air outlet 340; a sterilization light curtain is formed within the sterilization air duct S11; the sterilization air duct S11 is connected to the external environment through an air inlet 310. The impeller 400 is located within the air duct S12, which is connected to the external environment through an air outlet 320. That is, when the impeller 400 starts, the gas enters the sterilization air duct S11 through the air inlet 310, is treated by the sterilization light curtain, enters the air duct S12 through the air outlet 340, and is then discharged to the external environment through the air outlet 320.

[0081] In some embodiments, the wind turbine 400 may be an axial flow wind turbine 400 or a wind turbine 400.

[0082] In this embodiment, the impeller 400 is driven by an electric motor. The motor is mounted on the housing 300. The power supply 700 or an energy conversion device may also be configured to supply power to the motor.

[0083] This application also proposes a refrigeration device, which includes a sterilization and deodorization device 10. The sterilization and deodorization device 10 can be adopted from some or all of the foregoing embodiments, and therefore the refrigeration device has some or all of the technical advantages of the foregoing embodiments.

[0084] In this embodiment, the refrigeration equipment may be a refrigerator, freezer, beverage cooler, wine cooler, freezer box, ice cream machine, ice maker, air conditioner, etc.

[0085] In one embodiment, the refrigeration equipment includes a refrigerator; the refrigerator includes an inner liner, and the inner liner has a storage compartment, the storage compartment being equipped with the sterilization and deodorization device 10. Optionally, the storage compartment includes a refrigerator compartment and a freezer compartment, the refrigerator compartment being equipped with the sterilization and deodorization device 10, and / or the freezer compartment being equipped with the sterilization and deodorization device 10. In this embodiment, the air in the refrigerator compartment, after being sterilized and deodorized, is discharged back into the refrigerator compartment to sterilize and deodorize the air in the refrigerator compartment.

[0086] For example, the air inlet 310 is connected to the refrigerator compartment, and the air outlet 320 is also connected to the refrigerator compartment. When the fan starts, the gas in the refrigerator compartment is drawn into the air flow channel S1 through the air inlet 310 under the action of the rotating impeller 400. The electric field generated by the electric field sterilization device adsorbs and inactivates some bacteria or viruses. Then, the gas undergoes further sterilization treatment in the sterilization light curtain. Subsequently, the gas is discharged into the refrigerator compartment through the air outlet 320 under the action of the fan. When the gas passes through the air outlet 320, the ion catalysis module 600 further sterilizes and deodorizes the gas, so that the gas in the refrigerator compartment undergoes triple sterilization, including electric field sterilization, light curtain sterilization, and ion catalysis sterilization, thereby improving the sterilization and deodorization effect.
