[0003] In the existing sterilization and deodorization devices, the receiving electrodes of the discharge structure are mostly mesh structures. However, the mesh structure is not conducive to saving material costs, and its vertical ribs will hinder the flow of ion wind, so it needs to be improved.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0007] Another further object of the first aspect of the present invention is to ensure the discharge effect of the exciting electrode.

[0008] A further object of the first aspect of the present invention is to optimize the shape of the receiving electrode.

[0009] In particular, according to a first aspect of the present invention, the present invention provides a sterilization and deodorization device, comprising:

[0010] a housing defining a cavity therein; and

[0011] An electrode group is arranged in the cavity, comprising an excitation electrode and a receiving electrode, wherein the excitation electrode and the receiving electrode are arranged at intervals; wherein,

[0012] The excitation electrode has at least one discharge portion facing the receiving electrode, and the receiving electrode has a plurality of transverse segments arranged at intervals from top to bottom and configured to generate a potential difference between the excitation electrode and the receiving electrode.

[0014] The exciting electrode extends transversely in the cavity in a horizontal posture, and the receiving electrode extends transversely in the cavity in a vertical posture.

[0015] Optionally, the receiving electrodes are arranged vertically symmetrically with respect to a horizontal plane where the exciting electrodes are located.

[0016] Optionally, the discharge portion is in the shape of an isosceles triangle, and the angle between its two sides is 10° to 80°.

[0017] Optionally, the discharge portion has a discharge tip, and a curvature radius of the discharge tip is less than 900 um.

[0018] Optionally, the distance between the discharge tip and the receiving electrode is 5 mm to 20 mm.

[0019] Optionally, the receiving electrode includes four transverse segments and three connecting segments, the four transverse segments are arranged at intervals from top to bottom, the three connecting segments are arranged alternately at both ends of the four transverse segments, and each connecting segment connects two adjacent upper and lower transverse segments.

[0020] Optionally, the vertical spacings between adjacent transverse segments are equal.

[0021] Optionally, a connector is provided at the end of the receiving electrode, the connector is connected to a high-voltage wire harness, and a protective tube is sleeved on the high-voltage wire harness.

[0022] According to a second aspect of the present invention, the present invention provides a refrigerator comprising a sterilization and deodorization device as described in any one of the above.

[0023] The sterilization and deodorization device of the present invention has a cavity defined inside its shell, and an electrode group is arranged in the cavity. The electrode group includes an excitation electrode and a receiving electrode, and the excitation electrode and the receiving electrode are arranged at intervals. The excitation electrode has at least one discharge portion facing the receiving electrode, and the receiving electrode has a plurality of transverse segments arranged at intervals from top to bottom, configured to generate a potential difference with the excitation electrode. Compared with a mesh receiving electrode, the receiving electrode of the present invention can omit the vertical ribs, thereby increasing the outlet speed of the ion wind and optimizing the sterilization and deodorization effect.

[0024] Furthermore, in the sterilization and deodorization device of the present invention, the receiving electrodes are arranged symmetrically up and down with respect to the horizontal plane where the exciting electrodes are located.

DETAILED DESCRIPTION

[0040] Reference will now be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the accompanying drawings. The various embodiments provided are intended to explain the present invention, not to limit the present invention. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the present invention without departing from the scope or spirit of the present invention. For example, a feature illustrated or described as a part of one embodiment may be used together with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover such modifications and variations within the scope of the appended claims and their equivalents.

[0041] Refer to the following Figures 1 to 10 The refrigerator 1 and the sterilization and deodorization device 30 of the embodiment of the present invention are described. The directions or positional relationships indicated by "outside", "upper", "lower", "top", "bottom", "horizontal", and longitudinal directions are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. To facilitate the illustration of the structure of the device, some of the drawings of the present invention are illustrated in perspective.

[0042] In the description of this embodiment, it should be understood that the term "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. When a feature "includes or contains" one or some of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0043] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "some examples", "an example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0044] In one aspect, the present invention provides a sterilization and deodorization device 30. Figure 1 is a schematic front and side view of a sterilization and deodorization device 30 according to an embodiment of the present invention, Figure 2 is a schematic rear side view of a sterilization and deodorization device 30 according to an embodiment of the present invention, Figure 3 is a schematic exploded view of a sterilization and deodorization device 30 according to an embodiment of the present invention. Figure 4 is a schematic projection diagram of the excitation electrode 340 toward the receiving electrode 350 according to an embodiment of the present invention, Figure 5 is a schematic structural diagram of an excitation electrode 340 according to an embodiment of the present invention.

[0045] like Figures 1 to 5 As shown, the sterilization and deodorization device 30 of the embodiment of the present invention may include a housing 300 and an electrode group, wherein a cavity 301 is defined inside the housing 300, the electrode group is disposed in the cavity 301, and the electrode group includes an excitation electrode 340 and a receiving electrode 350, and the excitation electrode 340 and the receiving electrode 350 are arranged at intervals. The excitation electrode 340 can generate high-energy electrons, which move in a directional manner under the action of the electric field, collide with air molecules, and move the air molecules, thereby generating an ion wind blowing toward the side of the receiving electrode 350. While moving in a directional manner, the electrons break down the odor molecules, excite oxygen to produce ozone, and the high-voltage ionization discharge of the excitation electrode 340 breaks down the cells of the suspended organisms to sterilize.

[0046] It should be noted that corona discharge can be divided into positive polarity and negative polarity according to the polarity of the power supply voltage used. Regardless of the positive polarity or the negative polarity, the direction of the ion wind is from the high voltage electrode to the ground electrode. The excitation electrode 340 in this embodiment can be a high voltage electrode, and the receiving electrode 350 can be a ground electrode. In other words, the ion wind is blown from the excitation electrode 340 to the receiving electrode 350.

[0047] In an optional embodiment, the front side of the housing 300 defines an air inlet 302, the rear side of the housing 300 defines an air outlet 303, and the excitation electrode 340 and the receiving electrode 350 are sequentially arranged from the air inlet 302 to the air outlet 303. In addition, the excitation electrode 340 extends horizontally in the cavity 301, and the receiving electrode 350 extends horizontally in the cavity 301 in a vertical posture.

[0048] By adopting the above structure, the ion wind generated after the electrode group passes can be blown outward through the air outlet 303, so that a negative pressure is formed in the cavity 301, and the air in the external environment can be sucked into the cavity 301 through the air inlet 302, and after being sterilized and deodorized in the cavity 301, it is blown outward from the air outlet 303. In this way, the external environment in which it is located can be purified by the sterilization and deodorization device 30.

[0049] In one example, the housing 300 may include an upper cover 310 and a base 320, and the upper cover 310 and the base 320 are buckled together to form a cavity 301 therebetween. The air inlet 302 may be a narrow and long opening extending in the lateral direction of the housing 300, and an air outlet grille 330 may be provided at the air outlet 303. Since the air inlet 302 is a narrow and long opening, the wind pressure near it is relatively large, and the air inlet speed is relatively fast, so that the sterilization and deodorization device 30 can more fully process the gas flowing through, which is conducive to improving the sterilization and deodorization effect.

[0050] In an optional embodiment, the exciting electrode 340 has at least one discharge portion 342 facing the receiving electrode 350 , the receiving electrode 350 has a plurality of transverse segments 351 spaced from top to bottom, and the receiving electrode 350 is configured to generate a potential difference with the exciting electrode 340 .

[0051] By adopting the above structure, compared with the mesh receiving electrode 350, the receiving electrode 350 of the present invention can omit the vertical ribs, thereby increasing the outlet speed of the ion wind and optimizing the sterilization and deodorization effect.

[0052] In one example, the receiving electrodes 350 are arranged symmetrically about the horizontal plane where the exciting electrodes 340 are located. In this layout, the effect between the receiving electrodes 350 and the exciting electrodes 340 can be improved, so that the output of ion wind is higher, and the sterilization and deodorization efficiency of the sterilization and deodorization device 30 is effectively improved.

[0053] In an optional embodiment, the excitation electrode 340 may include a main body 341 and a plurality of discharge portions 342, wherein the main body 341 is in the shape of an elongated strip, and the plurality of discharge portions 342 are formed on one side of the main body 341 adjacent to the receiving electrode 350, for simultaneous discharge, thereby improving discharge efficiency. Each discharge portion 342 may be in the shape of an isosceles triangle, and the angle between its two waists is 10° to 80°, for example, 10°, 30°, 45°, 60°, 80°, etc. In other words, the discharge portion 342 is an acute triangle, which is more conducive to the concentration of high-energy electrons to the discharge portion 342.

[0054] Furthermore, the discharge portion 342 has a discharge tip 343, and the curvature radius of the discharge tip 343 may be less than 900um, such as 50um, 100um, 200um, 500um, 800um, 90um, etc. Since the smaller the curvature radius, the sharper the tip, the higher the surface charge density, and the stronger the field strength near it, it is easier to produce a tip effect and discharge more easily by controlling the curvature radius of the discharge tip 343 to be less than 900um, which can effectively ensure the discharge effect.

[0055] Furthermore, the distance between the discharge tip 343 and the receiving electrode 350 may be 5 mm to 20 mm, such as 5 mm, 8 mm, 10 mm, 15 mm, 20 mm, etc. Thus, the distance between the discharge tip 343 and the receiving electrode 350 may be limited to ensure the effect of the interaction between the two.

[0056] In an optional embodiment, a connector is provided at the end of the receiving electrode 350, the connector is connected to a high-voltage wire harness 360, and a protective tube 361 is sleeved on the high-voltage wire harness 360. Specifically, the high-voltage wire harness 360 and the connector can be welded and fixed to provide a voltage of -3kv for the receiving electrode 350, while the exciting electrode 340 can hold a voltage of +3kv. The protective tube 361 can be made of insulating materials, such as plastic, rubber, etc. The protective tube 361 mainly isolates the high-voltage wire harness 360 to prevent the rest of the high-voltage wire harness 360 from contacting the receiving electrode 350 again and causing a short circuit problem, so that the sterilization and deodorization device 30 is safer and more reliable during use.

[0057] In one example, the receiving electrode 350 may include four transverse segments 351 and three connecting segments 352, wherein the four transverse segments 351 are arranged at intervals from top to bottom, and the three connecting segments 352 are arranged alternately at both ends of the four transverse segments 351, and each connecting segment 352 connects two adjacent upper and lower transverse segments 351. In this way, the receiving electrode 350 can be arched as a whole, and the receiving electrode 350 forms a continuous structure through the four transverse segments 351 and the three connecting segments 352, so that the electrical connection of the receiving electrode 350 can be easily achieved.

[0058] It can be understood that if the receiving electrode 350 includes only four transverse sections 351, a connector needs to be provided at the end of each transverse section 351, and the four transverse sections 351 are connected in series through three connecting sections 352, and only a connector needs to be provided at the end of the topmost or bottommost transverse section 351, and connected to the high-voltage harness 360. This method can reduce the number of connectors, thereby reducing the high-voltage harness 360, and avoiding excessive high-voltage harness 360 and tangling together.

[0059] Furthermore, the vertical spacings between adjacent transverse segments 351 are equal. Thus, the effect of the action between the exciting electrode 340 and the receiving electrode 350 can be improved, and the ion wind can be uniformly generated.

[0060] In an optional embodiment, at least one fixing plate 321 is disposed in the housing 300, and the fixing plate 321 is located between the excitation electrode 340 and the receiving electrode 350, and the receiving electrode 350 is fixed to a side of the fixing plate 321 away from the excitation electrode 340. When the excitation electrode 340 or the receiving electrode 350 falls off, the fixing plate 321 can play a certain stopping role between the two, and can prevent the excitation electrode 340 and the receiving electrode 350 from contacting each other and causing a short circuit or other dangers.

[0061] It is found in actual applications that if ordinary screws are used to fix the receiving electrode 350, due to the small space of the base 320 and the long screw of the screwdriver, the base 320 will hinder the screw when screwing the screw, making the screwing operation very inconvenient, and the screwing depth of each screw is difficult to control, which can easily cause the receiving electrode 350 to be unevenly stressed and deformed.

[0062] In an optional embodiment, a hot melt head 323 may be provided on one side of the fixing plate 321 away from the exciting electrode 340, and a hot melt hole 353 is provided at the corresponding position of the receiving electrode 350 and the hot melt head 323, and the hot melt head 323 passes through the hot melt hole 353 to hot-melt the receiving electrode 350 and the fixing plate 321. In this way, the installation of the receiving electrode 350 is more convenient, the receiving electrode 350 is not easily deformed, and the fixation after hot melting is more secure.

[0063] Furthermore, there may be two fixing plates 321, which may be respectively disposed at both ends of the length direction of the receiving electrode 350. Thus, not only the fixing effect of the receiving electrode 350 can be improved, but also the fixing plates 321 can be prevented from obstructing the normal flow of the ion wind.

[0064] In one example, the end of the transverse section 351 can be designed to be an ear plate, and the hot melt hole 353 is opened on the ear plate. In this way, the size of the hot melt hole 353 can be enlarged, and the size of the hot melt column can be enlarged accordingly, thereby increasing the hot melt area of ​​the hot melt column and the receiving electrode 350, so that the receiving electrode 350 is fixed more firmly after hot melting.

[0065] In an optional embodiment, at least one fixing column 322 is further provided in the housing 300, the fixing column 322 is provided with a bottom hole 324 and equipped with a self-tapping screw 344, the excitation electrode 340 is provided with a through hole 345 corresponding to the bottom hole 324, and the self-tapping screw 344 passes through the bottom hole 324 and the through hole 345 to thread the excitation electrode 340 and the fixing column 322. The self-tapping screw 344 is not easy to loosen during transportation, which can improve the connection stability of the excitation electrode 340.

[0066] It should be noted that the diameter of the bottom hole 324 should be smaller than the diameter of the self-tapping screw 344. It mainly plays a force-relieving role to prevent the fixing column 322 from cracking during the process of screwing the self-tapping screw 344. The surrounding wall of the bottom hole 324 itself does not have threads. During the process of screwing the self-tapping screw 344, self-tapping teeth are formed on the surrounding wall of the bottom hole 324.

[0067] Furthermore, the number of the fixing posts 322 may be two, and the two fixing posts 322 may be respectively disposed at both ends of the length direction of the excitation electrode 340. Thus, the fixing effect of the excitation electrode 340 may be improved, and the excitation electrode 340 may be fixed more firmly.

[0068] In one example, the outer periphery of the self-tapping screw 344 may be coated with anti-falling glue. Anti-falling glue is also called anaerobic glue, thread fastening glue, thread locking agent, etc., and can be applied on the self-tapping screw 344 to prevent oxidation corrosion of the self-tapping screw 344, limit the circumferential rotation of the self-tapping screw 344, and ensure that the self-tapping screw 344 does not loosen under long-term vibration conditions.

[0069] In some examples, ribs may be provided around the fixing column 322 or the fixing plate 321, one side of the ribs being connected to the peripheral wall of the fixing column 322 or the fixing plate 321, and the bottom of the ribs being connected to the bottom wall of the base 320. Thus, the connection stability between the fixing column 322 or the fixing plate 321 and the base 320 may be improved, and fracture at the connection may be prevented.

[0070] During the ionization process, oxygen in the air can be oxidized into ozone, and a large amount of ozone can cause discomfort to the user. A small amount of ozone can enhance the sterilization and deodorization effect of the sterilization and deodorization device 30, but if a large amount of ozone is generated during the ionization process, there is a risk of causing "ozone poisoning" to the user.

[0071] In an optional embodiment, the sterilization and deodorization device 30 may further include a catalytic module 370, which is disposed on a side of the receiving electrode 350 away from the excitation electrode 340 and configured to have catalytic activity after being heated. When the ion wind passes through the catalytic module 370, a large amount of ozone and a small amount of odor molecules carried by the ion wind can be eliminated by the catalytic reaction.

[0072] In a preferred embodiment, the catalytic module 370 is a catalytic honeycomb block, which includes a substrate and a catalytic coating, wherein the substrate is ceramic or metal, and the catalytic coating is a precious metal and / or a transition metal oxide. The catalytic module 370 is a catalytic honeycomb block, that is, the catalytic module 370 uses a honeycomb catalyst. The characteristics of the honeycomb catalyst are large area, high activity, small catalyst volume, more catalytic active substances than other types, and catalytic regeneration can maintain activity, which can greatly reduce production costs and can be reused and recycled.

[0073] The substrate of the catalytic honeycomb block is ceramic or metal because it can generate heat when powered and is easy to adhere to the catalytic coating. The catalytic coating is a precious metal and / or transition metal oxide. Transition metals refer to a series of metal elements in the d zone of the periodic table, also known as transition elements. Since copper, silver, and gold also use d electrons when forming +2 and +3 valence compounds; zinc, cadmium, and mercury are similar to traditional transition elements in their ability to form stable coordination compounds, the ds zone where the above elements are located is often included in the transition metals.

[0074] The noble metal and / or transition metal oxide of the catalytic coating may be of nanometer level. For example, in a specific embodiment, the catalytic coating may be of nanometer noble metals: platinum, rhodium, palladium, etc. Of course, the catalytic coating may also be of nanometer MnOx, TiO2, ZnO, CdS, WO3, Fe2O3, PbS, SnO2, ZnS, SrTiO3, SiO2, etc.

[0075] In an optional embodiment, the catalytic module 370 is disposed adjacent to the receiving electrode 350, for example, the distance between the catalytic module 370 and the receiving electrode 350 is 3 mm to 10 mm, so that the receiving electrode 350 is clamped between the catalytic module 370 and the fixing plate 321. In this way, during transportation, even if all the hot melt columns are broken and the receiving electrode 350 is separated from the fixing plate 321, the receiving electrode 350 is clamped by the catalytic module 370 and the fixing plate 321 and will not come into contact with the exciting electrode 340, which can effectively prevent the danger of short circuit caused by the contact between the receiving electrode 350 and the exciting electrode 340.

[0076] In an optional embodiment, the sterilization and deodorization device 30 may further include an ultraviolet lamp 380, which is configured to emit ultraviolet light when turned on to irradiate the side of the catalytic module 370 away from the excitation electrode 340. After the ultraviolet lamp 380 is turned on, heat can be applied to the catalytic module 370, so that the catalytic module 370 has catalytic activity. Of course, the catalytic module 370 can also be configured to generate heat after being powered on, so that it has catalytic activity.

[0077] In an optional embodiment, the receiving electrode 350 may be a titanium electrode, a germanium electrode or a nickel electrode.

[0078] Preferably, the receiving electrode 350 is a titanium electrode. An oxide film will form on the titanium surface. The oxide film is usually not a single structure, and the composition and structure of the oxide vary with the generation conditions. Under normal circumstances, the interface between the oxide film and the environment may be TiO2, and the interface between the oxide film and the metal may be mainly TiO. There may be transition layers of different valence states in the middle, or even non-chemically equivalent oxides. This shows that the titanium oxide film has a multi-layer structure, and its generation process is not a simple direct reaction of titanium and oxygen. The oxide layer formed on the titanium surface has a protective effect on the electrode, which can effectively prevent the receiving electrode 350 from rusting and breaking.

[0079] In an optional embodiment, the excitation electrode 340 may be a stainless steel electrode, a germanium electrode or a nickel electrode.

[0080] Preferably, the excitation electrode 340 is a stainless steel electrode, such as stainless steel of grade 304 or above. Since the high-energy electrons and oxidative active particles such as ozone generated by the excitation electrode 340 move toward the receiving electrode 350 under the action of the electric field, the oxidation degree of the excitation electrode 340 is relatively low, so the use of stainless steel electrodes for the excitation electrode 340 can well solve the rust problem and reduce material costs.

[0081] Of course, the exciting electrode 340 and the receiving electrode 350 may also be made of germanium electrodes or nickel electrodes, which can also prevent corrosion and fracture. However, the price of germanium electrodes and nickel electrodes is high, and the manufacturing cost is relatively high.

[0082] Another aspect of the present invention provides a refrigerator 1, Fig.10 is a schematic structural diagram of a refrigerator 1 according to an embodiment of the present invention, referring to Fig.10 The refrigerator 1 may include a housing 10, and a storage compartment 20 is formed inside the housing 10. The storage compartment 20 may be configured as a refrigeration compartment, a freezing compartment, and a variable temperature compartment according to the refrigeration temperature. Specifically, the number, function, layout, etc. of the storage compartment 20 may be configured according to actual needs.

[0083] Furthermore, the refrigerator 1 may also include the above-mentioned sterilization and deodorization device 30. The sterilization and deodorization device 30 can be arranged in the storage compartment 20 of the refrigerator 1, or can be arranged on the inside of the door body corresponding to the storage compartment 20, or can be arranged in a specific independent environment of the refrigerator 1, such as a sealed drawer, a sealed bottle holder, etc.

[0084] When the sterilization and deodorization device 30 is arranged in the storage compartment 20, it can be specifically arranged on the top wall, bottom wall, rear wall or side wall of the storage compartment 20. Of course, if a shelf is arranged in the storage compartment 20, the sterilization and deodorization device 30 can also be placed on the shelf.

[0085] The air in the storage room 20 may initially contain air molecules, suspended organisms, and odor molecules. The high-energy motor generated by the tip of the excitation electrode 340 collides with the molecules in the air, causing the gas molecules to move and generate wind blowing toward the receiving electrode 350. The high-voltage ionization discharge breaks down the cells of the suspended organisms, so that the wind passing through the receiving electrode 350 only includes air molecules and odor molecules. The odor substances are then eliminated by the catalytic module 370, and the purified ion wind blown out from the catalytic module 370 only has air molecules, and the cleanliness is very high.

[0086] That is to say, the air inlet 302 and the air outlet 303 of the sterilization and deodorization device 30 of the present invention are connected to the internal space of the storage room 20, and the air in the storage room 20 can circulate through the sterilization and deodorization device 30, thereby being continuously purified by the sterilization and deodorization device 30.

[0087] The refrigerator 1 may also include a compression refrigeration system to provide cold air to the storage compartment 20. The compression refrigeration system provides different cold air to various types of storage compartments 20, so that the temperature in various types of storage compartments 20 is also different. The temperature in the refrigerator compartment is generally between 2°C and 10°C, preferably 4°C to 7°C. The temperature range in the freezer compartment is generally between -22°C and -14°C. The optimal storage temperature for different types of items is not the same, and thus the storage compartments suitable for storage are also different. For example, fruit and vegetable foods are suitable for storage in the refrigerator compartment or the fresh-keeping compartment, while meat foods are suitable for storage in the freezer compartment.

[0088] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
