[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] 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 the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. 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.

[0031] Please see Figure 1 and Figure 2 This application provides a sterilization and deodorization device 100, which includes a box 20. The box 20 is provided with an ultraviolet lamp 81, an ultrasonic device 82 and an adsorbent material (not shown). The ultraviolet lamp 81 and the ultrasonic device 82 are used for sterilization, and the adsorbent material is used for adsorbing odors.

[0032] It is understandable that ultraviolet sterilization mainly works by destroying the nucleic acid (DNA or RNA) structure of microorganisms, thereby affecting their growth, reproduction and metabolism, ultimately leading to their death and achieving the purpose of sterilization.

[0033] Understandably, ultrasound can accelerate the movement and combination of photogenerated electrons, water vapor molecules, and oxygen molecules in the air, generating strong oxidizing substances. These substances can attack the cell walls and cell membranes of bacteria, damaging their structure and causing the cell contents to leak out, thus depriving bacteria of their basis for survival and achieving efficient and rapid elimination of bacteria. On the other hand, ultrasound can generate cavitation and mechanical effects when it propagates in the air, enabling efficient sterilization of hard-to-clean corners and crevices inside the refrigerator.

[0034] It should be noted that the vibration of ultrasound can also accelerate the movement of odor molecules, causing them to migrate to the surface of the adsorbent material (activated carbon) more quickly, thus accelerating the absorption rate of odor molecules by the adsorbent material (activated carbon).

[0035] It should be noted that after the activated carbon has fully adsorbed odor molecules, it can be placed under an ultraviolet lamp for a period of time to decompose and activate the odor molecules using ultraviolet light, thus enabling the activated carbon to be reused quickly and efficiently.

[0036] For example, the adsorbent material is a porous adsorbent material, and in some embodiments, the porous adsorbent material is activated carbon.

[0037] The sterilization and deodorization device 100 provided in this application embodiment can be applied to refrigeration equipment such as refrigerators. By setting an ultraviolet lamp 81 and an ultrasonic device 82 inside the box 20, ultraviolet light and ultrasonic waves can be used to kill bacteria and other microorganisms in the environment. By setting an adsorbent material inside the box 20, the adsorbent material can be used to adsorb odors in the environment, thereby achieving sterilization and deodorization effects, and thus extending the shelf life and safe consumption period of food in the refrigerator.

[0038] Please see Figure 3 and Figure 4 The inner surface of the box 20 is provided with a photoresponsive antibacterial coating 83, which includes a photocatalytic coating and / or a metallic silver coating.

[0039] For example, the material of the photocatalytic coating includes titanium dioxide.

[0040] Understandably, by applying a photocatalytic coating to the inner surface of the housing 20, when the coating is irradiated with ultraviolet light, electrons in the valence band of the photocatalytic material are excited and jump to the conduction band, forming electron-hole pairs. These holes have strong oxidizing properties and can react with water or hydroxide ions adsorbed on the photocatalyst surface to generate highly oxidizing hydroxyl radicals. Simultaneously, electrons in the conduction band can react with oxygen adsorbed on the photocatalyst surface to generate superoxide anion radicals. These reactive oxygen species have extremely high reactivity and can rapidly react with various biomolecules within microbial cells, destroying the structure and physiological functions of bacteria, viruses, and other microorganisms, thereby achieving an antibacterial effect.

[0041] It is understandable that by setting a metallic silver coating on the inner surface of the box 20, when the metallic silver coating is irradiated by ultraviolet light, the metallic silver coating can act as a photocatalyst, causing oxygen and water in the surrounding environment to react and produce a variety of reactive oxygen species (ROS), such as superoxide anion free radicals, hydroxyl free radicals and singlet oxygen. These reactive oxygen species have extremely strong oxidizing properties and can attack the biomacromolecules in microbial cells, destroying the structure and physiological functions of bacteria, viruses and other microorganisms, thereby achieving the effect of inhibiting bacteria.

[0042] In some embodiments, the photocatalytic coating is disposed on the inner surface of the housing 20, and the metallic silver coating is disposed on the inner surface of the photocatalytic coating (i.e., the side of the photocatalytic coating facing away from the housing 20).

[0043] Please see Figure 1 , Figure 2 and Figure 3 The sterilization and deodorization device 100 also includes an odor sensor 91 and a display 92. The odor sensor 91 and the display 92 are both installed on the outer surface of the housing 20. The odor sensor 91 is used to detect the concentration of odor gases in the environment, and the display 92 is used to display the concentration of odor gases captured by the odor sensor 91.

[0044] For example, the odor sensor 91 and the display 92 are either communicatively or electrically connected.

[0045] Understandably, by setting an odor sensor 91 to detect the concentration of odor gases in the environment, and a display 92 to display the concentration of odor gases captured by the odor sensor 91, the user can be reminded to perform corresponding operations (such as replacing the adsorption material, turning on the ultraviolet lamp 81, turning on the ultrasonic device 82, etc.) by displaying the concentration value of the odor gas on the display 92. For example, when the concentration of odor gas in the refrigerator exceeds the set value, the display 92 can display the concentration value in red to attract the user's attention.

[0046] Please seeFigure 1 and Figure 4 The box body 20 includes a lid assembly 31 and a first frame 51. The lid assembly 31 and the first frame 51 enclose a first inner cavity 11. The ultraviolet lamp 81 and the ultrasonic device 82 are both located in the first inner cavity 11.

[0047] For example, the lid assembly 31 and the first frame 51 can be detachably connected, or the lid assembly 31 can be attached to the first frame 51 to facilitate opening the first inner cavity 11 to replace or repair the ultraviolet lamp 81 and / or the ultrasonic device 82.

[0048] Please see Figure 2 and Figure 4 The first inner cavity 11 is provided with a first partition 511. The two ends of the first partition 511 are respectively connected to the opposite sides of the first frame 51. The first partition 511 divides the first inner cavity 11 into a first chamber 111 and a second chamber 112. The ultraviolet lamp 81 is disposed in the first chamber 111 and the ultrasound device 82 is disposed in the second chamber 112.

[0049] For example, the lid assembly 31 can be a single unit, or the lid assembly 31 can include a first lid 31 and a second lid 31, the first lid 31 covering the opening of the first chamber 111 and the second lid 31 covering the opening of the second chamber 112.

[0050] Please see Figure 2 and Figure 4 The ultraviolet lamp 81 is mounted on the first frame 51 and / or the first partition 511, and the ultrasonic device 82 is mounted on the first frame 51 and / or the first partition 511.

[0051] Please see Figure 1 and Figure 4 The box body 20 also includes a first top plate 41 and a second frame 52. One end of the first frame 51 away from the box cover assembly 31 and one end of the second frame 52 are both connected to the first top plate 41. The second frame 52 and the first top plate 41 together enclose a second inner cavity 12, which is connected to the first inner cavity 11.

[0052] The inner surface of the second frame 52 is provided with a photoresponsive antibacterial coating 83, which includes a photocatalytic coating and / or a metallic silver coating.

[0053] It should be noted that by connecting the first inner cavity 11 and the second inner cavity 12, ultraviolet light can enter the second inner cavity 12 from the first inner cavity 11, thereby irradiating the photoresponsive antibacterial coating 83 on the inner surface of the second frame 52, so as to promote a photocatalytic reaction in the box 20, thereby producing strong oxidizing substances (active oxygen, etc.) with antibacterial effect.

[0054] In some embodiments, the photocatalytic coating is disposed on the inner surface of the housing 20, and the metallic silver coating is disposed on the inner surface of the photocatalytic coating (i.e., the side of the photocatalytic coating facing away from the housing 20).

[0055] Please see Figure 4 For example, the first top plate 41 has a first inner edge and a first outer edge disposed opposite to each other. The first inner edge of the first top plate 41 is connected to one end of the first frame 51 away from the lid assembly 31, and the first outer edge of the first top plate 41 is connected to one end of the second frame 52.

[0056] Please see Figure 1 The first frame 51 has a first outlet 61 on the part corresponding to the first chamber 111, and a second outlet 62 on the part corresponding to the second chamber 112; the second frame 52 has a third outlet 63.

[0057] Please see Figure 1 and Figure 4 The sterilization and deodorization device 100 also includes a first control button 71, which is installed on the outer surface of the box 20. The first control button 71 is used to turn on the ultraviolet lamp 81 and close the first outlet 61, the second outlet 62 and the third outlet 63.

[0058] In some embodiments, the first control button 71 is mounted on the portion of the first frame 51 corresponding to the first chamber 111.

[0059] Please see Figure 1 and Figure 4 The sterilization and deodorization device 100 also includes a second control button 72, which is installed on the outer surface of the box 20. The second control button 72 is used to turn on the ultrasonic device 82 and open the first outlet 61, the second outlet 62 and the third outlet 63 when the ultraviolet lamp 81 stops irradiating.

[0060] In some embodiments, the second control button 72 is mounted on the portion of the first frame 51 corresponding to the second chamber 112.

[0061] It should be noted that when the UV lamp 81 is used to irradiate the photoresponsive antibacterial coating 83, in order to prevent the UV light from leaking into the refrigerator storage compartment and affecting the stored food, this embodiment of the application provides a first control button 71, which can close the first outlet 61, the second outlet 62 and the third outlet 63 at the same time as the UV lamp 81 is turned on, thereby sealing the first inner cavity 11 and the second inner cavity 12 to prevent UV leakage.

[0062] It should be noted that when the ultraviolet light irradiation of the photoresponsive antibacterial coating 83 ends, the ultrasonic device 82 can be started by the second control button 72, and the first outlet 61, the second outlet 62 and the third outlet 63 can be opened so that the strong oxidizing substances (active oxygen, etc.) generated in the first inner cavity 11 and the second inner cavity 12 can volatilize and enter the refrigerator to achieve a sterilization effect.

[0063] Understandably, the first outlet 61, the second outlet 62, and the third outlet 63 can all be used to allow the active antibacterial substances generated in the inner cavity of the box to volatilize and diffuse into the refrigerator storage compartment after the photoresponsive antibacterial coating 83 is irradiated with ultraviolet light. The first outlet 61 can also allow ultraviolet light to be emitted to disinfect the refrigerator when necessary, and the second outlet 62 can allow ultrasonic waves to pass through the refrigerator storage compartment to sterilize and disinfect the storage compartment.

[0064] Please see Figure 1 and Figure 4 The box body 20 further includes a second top plate 42, a third frame 53, and a box bottom 32. One end of the second frame 52 facing away from the first top plate 41 and one end of the third frame 53 are both connected to the second top plate 42. The other end of the third frame 53 is connected to the box bottom 32. The second top plate 42, the third frame 53, and the box bottom 32 together enclose a third inner cavity 13. The absorbent material (not shown) is disposed in the second inner cavity 12. The third frame 53 is provided with a fourth outlet 64. The second inner cavity 12 and the third inner cavity 13 are separated by a second partition 522. The second partition 522 is connected to the second frame 52 and / or the second top plate 42.

[0065] It is understandable that by providing a fourth outlet 64 on the third frame 53, odorous gases in the refrigerator compartment can enter the third inner cavity 13 through the fourth outlet 64 and be adsorbed by the adsorption material.

[0066] It should be noted that by using the second partition 522 to separate the second inner cavity 12 and the third inner cavity 13, ultraviolet rays can be prevented from entering the third inner cavity 13 and affecting the adsorbent material (such as activated carbon).

[0067] For example, a reflective layer may be provided on the side of the second partition 522 facing away from the bottom 32 of the box to reflect ultraviolet rays, so that more ultraviolet rays can irradiate the photoresponsive antibacterial coating 83 on the inner wall of the second frame 52. For example, the reflective layer may be made of metal, metal oxide, or a composite optical film.

[0068] Please see Figure 4 For example, the second top plate 42 has a second inner edge and a second outer edge disposed opposite to each other. The second inner edge of the second top plate 42 is connected to one end of the second frame 52 away from the first top plate 41, and the second outer edge of the second top plate 42 is connected to one end of the third frame 53.

[0069] For example, the material of the box body 20 can be metal or plastic, etc.

[0070] For example, the first top plate 41 and the second top plate 42 are parallel to each other, and the first frame 51, the second frame 52 and the third frame 53 are all perpendicular to the first top plate 41 and the second top plate 42.

[0071] This application also provides a refrigeration device, including the sterilization and deodorization device 100 in any of the above embodiments.

[0072] For example, the refrigeration equipment has a storage room inside, and the sterilization and deodorization device 100 is installed in the storage room.

[0073] For example, the refrigeration equipment can be a refrigerator, freezer, beverage cooler, wine cooler, freezer box, ice cream machine, ice maker, etc.

[0074] The sterilization and deodorization device and refrigeration equipment provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
