Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a sterilization and purification device. Background Technology

[0002] As society develops and people's living standards improve, the pace of life becomes faster and faster. As a result, people are more willing to buy a lot of food and store it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily lives.

[0003] However, due to the long-term storage of various foods in the refrigerator, bacteria can easily grow inside. At the same time, the reproduction of bacteria and other microorganisms and the long-term placement of different foods in a closed space can produce odors. In addition, a large number of large particulate pollutants such as dust are suspended in the air inside and outside the refrigerator, which can provide a relatively safe hiding place for bacteria, viruses and other microorganisms, and can also absorb odor particles, reducing the refrigerator's purification function.

[0004] In existing technologies, most refrigerators are equipped with sterilization components to sterilize the air inside the refrigerator, thus solving the problems of bacterial growth and odor. However, current active sterilization and purification technologies for refrigerators typically employ a single sterilization and purification technology, such as ion sterilization, ultraviolet sterilization, ozone sterilization, or photocatalytic sterilization. This results in limited sterilization and purification effectiveness and leaves considerable room for improvement.

[0005] Therefore, it is necessary to propose a sterilization and purification device to solve or at least alleviate the above-mentioned defects. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0036] Please see the attached Figures 1 to 7 A sterilization and purification device 1 according to one embodiment of the present invention includes a base 10, a sterilization and purification component 20, and a housing 30 with an open top.

[0037] The base 10 is connected to the top of the housing 30 and is used to connect the refrigerator liner. For example, a snap-fit ​​groove can be provided in the refrigerator liner and a snap-fit ​​connector can be provided in the corresponding position of the base 10, and the connection can be achieved by snapping the two together.

[0038] A receiving cavity 310 is formed between the housing 30 and the base 10. A baffle 340 is provided on the inner wall of the bottom plate of the housing 30, which divides the receiving cavity 310 into a first chamber 311 and a second chamber 312. An air inlet 320 communicating with the first chamber 311 is opened on the side wall of the housing 30, and an air outlet 330 communicating with the second chamber 312 is opened on the bottom of the housing 30. The baffle 340 can effectively divide the receiving cavity 310, so that after the air enters from the air inlet 320, it will not be directly discharged through the air outlet 330, but will pass through the sterilization and purification component 20 of this application in sequence and then be discharged through the air outlet 330.

[0039] The sterilization and purification component 20 is disposed in the first chamber 311. The sterilization and purification component 20 includes a pre-filter component 210, a disinfection and sterilization component 220, a pollutant particle filter component 230 and a circulating fan 240 arranged sequentially along the air flow direction. The pre-filter component 210 is disposed near the air inlet 320, and the circulating fan 240 is disposed away from the air inlet 320. The circulating fan 240 includes an air inlet end (not shown in the figure) and an air outlet end 241. The air inlet end is disposed near the pollutant particle filter component 230. The enclosure 340 has an air passage hole 341 that matches the air outlet end 241 so that air from the air outlet end 241 enters the refrigerator compartment 50 through the air outlet 330.

[0040] Specifically, air enters the first chamber 311 through the air inlet 320 on the side wall of the housing 30. In the first chamber 311, the air passes sequentially through the pre-filter assembly 210, the disinfection and sterilization assembly 220, and the pollutant particle filter assembly 230. After filtration and sterilization, the air is drawn in through the air inlet of the circulating fan 240 and discharged through the air outlet 241 of the circulating fan 240. The air outlet 241 of the circulating fan 240 is connected to the second chamber 312 through the air passage 341 on the enclosure 340. Air enters the second chamber 312 through this air inlet and then enters the refrigerator compartment 50 through the air outlet 330 at the bottom of the housing 30, thereby achieving air circulation, sterilization, and purification in the refrigerator compartment 50.

[0041] The pre-filter component 210 is used to initially filter large particulate pollutants in the air. It can be a common pre-filter component 210 in the prior art, such as an activated carbon pre-filter component 210. The disinfection and sterilization component 220 preferably uses a composite layer of granular activated carbon and silver ion filter, which has a better disinfection and sterilization function. The pollutant particle filter component 230 is used to further filter fine particulate pollutants in the air. It preferably uses a HEAP layer (a high-efficiency air filter, mainly used to filter small particulate matter in the air). The circulating fan 240 provides power to circulate the air in the device and delivers the treated air into the refrigerator compartment 50.

[0042] This application effectively removes harmful substances such as bacteria, viruses, and particulate matter from the air through multiple processes including pre-filtration, disinfection and sterilization, and filtration of pollutants, thus significantly improving the air quality inside the refrigerator compartment 50. A circulating fan 240 ensures continuous air circulation within the device, and the treated air is then reintroduced into the refrigerator compartment 50, guaranteeing effective purification of the air throughout the entire compartment. This application features a compact structure, making it easy to install and disassemble. The sterilization and purification device 1 is not only suitable for the refrigerator compartment 50 but can also be applied to other scenarios requiring air purification and sterilization.

[0043] In a preferred embodiment, the inner wall of the bottom plate of the housing 30 is provided with an upwardly protruding connecting post 350. The connecting post 350 has a first vertical connecting hole 351 for screw 120 connection. The base has a second vertical connecting hole 110 corresponding to the first vertical connecting hole 351. The housing 30 is connected to the base 10 by screw 120 passing through the second vertical connecting hole 110, the first vertical connecting hole 351, and the base 10. The connection method of this embodiment simplifies the installation process, improves installation efficiency, and facilitates subsequent disassembly and maintenance.

[0044] In a preferred embodiment, a first space 360 ​​is formed between the disinfection and sterilization component 220 and the pollution particle filtration component 230, and a second space 370 is formed between the pollution particle filtration component 230 and the circulating fan 240. An ultraviolet sterilization component 361 is disposed in the first space 360, and a negative ion sterilization and purification component is disposed in the second space 370.

[0045] Specifically, the UV sterilization component 361 utilizes the high-energy characteristics of ultraviolet light to achieve efficient sterilization and disinfection, and can employ existing, mature UV sterilization devices. The negative ion sterilization and purification component releases negative ions, which can be used for sterilization and deodorization, and can also employ existing, mature UV sterilization devices. This example further enhances the sterilization and purification effect.

[0046] Therefore, in conjunction with the above embodiments, air enters the sterilization and purification device 1 through the air inlet 320, and is initially removed from the refrigerator by the pre-filter component 210 to remove large particulate pollutants. Then, it enters the disinfection and sterilization component 220, where the air undergoes preliminary sterilization (e.g., sterilization by the silver ion filter in the disinfection and sterilization component 220) and preliminary deodorization (e.g., deodorization by the granular activated carbon in the disinfection and sterilization component 220). Finally, it enters the first space 360 ​​formed by the disinfection and sterilization component 220 and the pollutant particle filter component 230 for ultraviolet sterilization and disinfection, while simultaneously removing pollutant particles. The filter component 230 (e.g., a HEAP layer) can effectively prevent large particulate pollutants such as dust from passing through, allowing bacteria and viruses adsorbed on its surface to be fully killed by ultraviolet light. After being fully filtered by the pollutant particle filter component 230, the air in the second space 370 formed by the pollutant particle filter component 230 and the circulating fan 240 undergoes negative ion sterilization, purification, and deodorization treatment. Furthermore, the negative ions generated by the negative ion sterilization and purification component are returned to the refrigerator compartment 50 through the air outlet 330 under the action of the circulating fan 240, further sterilizing and deodorizing the air inside the refrigerator.

[0047] Furthermore, the housing 30 is in the shape of a frustum, which is larger at the top and smaller at the bottom, and the top of the housing 30 is open.

[0048] As a preferred embodiment, such as Figure 4-5As shown, the inner wall of the enclosure 340 has a first vertical insertion slot 342 for the pre-filtration component 210 to be inserted, a second vertical insertion slot 343 for the disinfection and sterilization component 220 to be inserted, and a third vertical insertion slot 344 for the contaminant particle filter component 230 to be inserted. The pre-filtration component 210 is inserted into the first vertical insertion slot 342, the disinfection and sterilization component 220 is inserted into the second vertical insertion slot 343, and the contaminant particle filter component 230 is inserted into the third vertical insertion slot 344. This embodiment, through the insertion slots and component insertion method, greatly simplifies the installation and disassembly process.

[0049] As a preferred example, there are multiple air inlets 320, which are evenly spaced and arranged on the side wall of the housing 30. It is understood that the number and size of the air inlets 320 can be set according to actual needs; as a specific example, the number of air inlets 320 is set to 13.

[0050] In another preferred embodiment, a decorative cover assembly 40 is also included at the bottom of the housing 30. The decorative cover assembly 40 includes an outer decorative cover 410 and an inner decorative cover 420. The inner decorative cover 420 is detachably connected to the housing 30, while the outer decorative cover 410 and the inner decorative cover 420 are fixedly connected. The bottom of the outer decorative cover 410 and the bottom of the housing 30 form an air supply channel 430. Specifically, the outer decorative cover 410, as the visible part of the bottom of the housing 30, is often designed with aesthetics in mind. The inner decorative cover 420 is located between the housing 30 and the outer decorative cover 410, serving to protect the internal structure and components of the housing 30. The air supply channel 430 formed between the outer decorative cover 410 and the bottom of the housing 30 allows air to flow from inside the housing 30 through the air outlet 330 and then into the refrigerator compartment 50 through the nearly horizontal air supply channel 430.

[0051] Furthermore, the outer wall of the bottom plate of the housing 30 is provided with a buckle (not shown in the figure), and the inner decorative cover 420 has a third connecting hole (not shown in the figure) that matches the buckle. The buckle is engaged with the third connecting hole to make the housing 30 and the inner decorative cover 420 detachably connected. By adopting a buckle connection method, the installation and disassembly process is simple and quick.

[0052] Furthermore, the diameter of the air inlet 320 is larger than the diameter of the air outlet 330.

[0053] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
