Description

TECHNICAL FIELD

[0002] At present, users pay more and more attention to the hygiene problem of the refrigeration device. Taking a refrigerator as an example, at present, the freezing compartment and the ice-making compartment of the refrigerator usually share a large freezing space and an air duct. The freezing compartment usually has food with odor properties such as seafood and meat, and the ice-making box is used to store ice. Since the freezing compartment and the ice-making box share an air duct, the ice is prone to odor transfer. At the same time, if the refrigerating compartment, the freezing compartment and the ice-making compartment also share an air duct, the odor molecules generated by the odor food such as durian, onion, pickles, leftovers and the like in the refrigerating compartment will enter the freezing compartment and then enter the ice-making compartment, thereby causing the ice to have odor and being prone to bacterial growth. It is necessary to sterilize and disinfect and purify the odor of the refrigeration device. However, the surface of the existing catalyst assembly for sterilizing and disinfecting and purifying the refrigeration device is prone to icing or frosting, and the ice or frost will block the adsorption sites of the catalyst assembly, greatly reducing the adsorption effect of the catalyst assembly.

[0070] The refrigeration equipment is a device for cooling or reducing temperature, which can be a refrigerator or a freezer for storing and preserving food and other perishable items, and the present application is not particularly limited herein. In order to more specifically describe the control method of the catalyst assembly 100 of the refrigeration equipment of the present application, the following will be described as a refrigerator as a use scenario.

[0071] According to the control method of the catalyst assembly 100 of the refrigeration equipment according to the first aspect of the present application, please refer to Figure 1 (Catalyst assembly 100 and heating member 400 can refer to Figures 8 to 10 , accommodating chamber 301 and ozone sensor 340 can refer to Figure 16 ), the control method of the catalyst assembly 100 of the refrigeration equipment comprises:

[0072] Step 10: determining that the catalyst assembly 100 is started, and obtaining the ozone concentration of the accommodating chamber 301, wherein the refrigeration equipment is internally formed with the accommodating chamber 301, and the catalyst assembly 100 is arranged in the accommodating chamber 301.

[0073] Step 20: determining that the ozone concentration is greater than the first set concentration value, controlling the catalyst assembly 100 to stop, and controlling the heating member 400 of the catalyst assembly 100 to start, wherein the heating member 400 is used for heating the catalyst block 1200 of the catalyst assembly 100.

[0074] According to the control method of the catalyst assembly 100 of the refrigeration equipment according to the present application, by heating the catalyst block 1200 through the heating member 400, the ice or frost attached to the catalyst block 1200 can be changed into water or vapor to leave the catalyst block 1200, and the adsorption sites on the catalyst block 1200 are re-released, so that the adsorption sites on the catalyst block 1200 are not blocked by ice or frost, and the catalyst block 1200 can maintain high-efficiency catalytic effect.

[0075] In step 10, the ozone concentration of the accommodating chamber 301 can be obtained through the ozone sensor 340. The ozone sensor 340 can be arranged at multiple positions of the accommodating chamber 301, so as to comprehensively monitor the ozone level of the whole accommodating chamber 301, and ensure that the obtained ozone concentration is more accurate.

[0076] In step 20, the first set concentration value can be set as 50 ppb (parts per billion). It can be understood that ozone is a gas with strong oxidizing property, and at high concentration, it can have adverse effects on food. When food is exposed to an environment with high concentration of ozone, ozone can react with nutrients and odor molecules in the food, causing deterioration and quality decline of the food. When the catalyst assembly 100 is activated, it detects whether the ozone concentration exceeds 50 ppb, and when the ozone concentration is greater than 50 ppb, the catalyst assembly 100 is controlled to stop, so as to avoid the ozone concentration in the containing chamber 301 becoming a new source of odor. Of course, the first set concentration value can also be other, and the present application is not limited by the embodiment.

[0077] In step 20, the catalyst block 1200 is used to adsorb odor molecules in the containing space, and the odor molecules herein also include ozone generated by the catalyst assembly 100 ionizing air. When the catalyst assembly 100 is arranged in the refrigeration equipment, especially when the catalyst assembly 100 is arranged in the containing space of the refrigerator, every operation of the refrigerator will produce water vapor, which will continuously adhere to the catalyst assembly 100, and with the refrigeration of the refrigerator, the water vapor will condense into frost, which will cause the catalyst block 1200 to continuously accumulate frost, blocking the adsorption sites of the catalyst block 1200 for odor molecules, affecting the adsorption of the catalyst block 1200 for odor molecules. The heating member 400 can heat and warm the catalyst block 1200, melt the ice adhering to the catalyst block 1200, release the adsorption sites on the catalyst block 1200, and thus restore the catalytic effect of the catalyst assembly 100. The heating member 400 can wrap the outer surface of the catalyst block 1200 or part of the outer surface of the catalyst block 1200, so as to achieve better heating efficiency.

[0078] According to an embodiment of the present application, please refer to Figure 2 (the heating member 400 can refer to Figure 8 ), the step 20 of controlling the heating member 400 of the catalyst assembly 100 to start, comprising:

[0079] Step 21: obtaining the working state of the refrigeration circuit of the refrigeration equipment;

[0080] Step 22: determining that the refrigeration circuit is not in a refrigeration state, and controlling the heating member 400 to operate.

[0081] In step 22, the refrigeration circuit not being in a refrigeration state means that in addition to the refrigeration circuit being in a refrigeration state, the refrigeration circuit needs to be switched for maintenance and optimization of equipment performance. For example, not being in a refrigeration state includes:

[0082] Stop state: When the refrigeration device is in a closed or stopped state, the compressor is in a stop state. In this state, the compressor does not run or produce a refrigeration effect. For example, when the refrigeration device is a refrigerator, the refrigerator can be a compressor type refrigerator, which uses a compressor to circulate refrigerant to achieve refrigeration. When the temperature of the refrigeration chamber or freezing chamber rises to the set upper limit, the compressor starts to suck refrigerant from the evaporator, releases heat to the external environment through compression and condensation, thereby reducing the temperature of the refrigeration chamber or freezing chamber. Once the temperature drops to the set lower limit, the compressor will stop working until the temperature rises again. This can avoid unnecessary energy consumption and reduce the risk of wear and tear and failure of the compressor.

[0083] Defrosting state: In some cases, ice layers may accumulate on the surface of the evaporator, affecting its normal operation. To remove the ice layer, the refrigeration device enters a defrosting state. In this state, the compressor may stop running, while other elements such as heaters provide heat to melt the ice layer. For example, when the refrigeration device is a direct-cooling refrigerator, the refrigeration cycle system directly sends refrigerant to the evaporator surface of the refrigeration chamber. When the air moisture contacts the evaporator, it condenses into water droplets and freezes, forming an ice layer that needs to be defrosted regularly to maintain its normal working effect. Therefore, when the refrigerator is in a defrosting state, the heating element 400 is also turned on to defrost the catalyst block 1200, avoiding unnecessary energy consumption.

[0084] According to one embodiment of the present application, please refer to Figure 3 (Odor sensor 350 and containing chamber 301 can refer to Figure 16 ), the control method of the catalyst assembly 100 of the refrigeration device further comprises:

[0085] Step 30: Obtain the odor molecule concentration of the containing chamber 301;

[0086] Step 40: Determine that the odor molecule concentration is less than the second set concentration value, and determine that the ozone concentration is less than the first set concentration value, and control the catalyst assembly 100 to stop working after running for a set period of time.

[0087] In step 30, the odor molecule concentration of the containing chamber 301 can be obtained by the odor sensor 350. The odor sensor 350 can be arranged at multiple positions of the containing chamber 301, which can comprehensively monitor the odor molecule concentration level of the entire containing chamber 301, ensuring that the obtained odor molecule concentration data is more accurate.

[0088] In step 40, the second set concentration value can be set as 10 ppb. The catalyst assembly 100 can completely catalytically purify the odor molecules with a concentration less than 10 ppb in a set time length. For example, in some embodiments, the set time length can be 15 min. When the odor molecule concentration value is determined to be less than 10 ppb and the ozone concentration is determined to be less than the first set concentration value, the catalyst assembly 100 can be controlled to stop running after 15 min. It should be noted that the set time length of 15 min is only an example, and the present application does not limit the specific value of the set time length.

[0089] If the odor molecule concentration value is determined to be less than 10 ppb but the ozone concentration is greater than the first set concentration value, it indicates that the catalytic purification efficiency of the catalyst assembly 100 is weak, and it can be that a layer of ice or frost is deposited on the catalyst block 1200, blocking the adsorption sites of the catalyst block 1200. The catalyst block 1200 needs to be heated by the heating element 400 to release the adsorption sites of the catalyst block 1200 and restore the original catalytic purification efficiency. Before the heating element 400 is started, it is necessary to determine whether the refrigeration circuit is in a refrigeration state. If the refrigeration circuit is not in a refrigeration state, the heating element 400 can be heated for a period of time, for example, the heating element 400 can be heated for 10 min, and the original adsorption effect of the catalyst assembly 100 can be restored. If the refrigeration circuit is in a refrigeration state, the operation of the catalyst assembly 100 is stopped to avoid the continuous generation of ozone by the catalyst assembly 100, which causes the ozone to become a new odor source.

[0090] According to an embodiment of the present application, please refer to Figure 4 The control method of the catalyst assembly 100 of the refrigeration equipment further comprises:

[0091] Step 30: obtaining the odor molecule concentration of the containing chamber 301;

[0092] Step 50: determining that the odor molecule concentration is greater than the second set concentration value and determining that the ozone concentration is less than the first set concentration value, and controlling the catalyst assembly 100 to continue to work.

[0093] In step 50, the second set concentration value can be set as 10 ppb. For example, if the odor molecule concentration value is determined to be greater than 10 ppb and the ozone concentration is determined to be less than the first set concentration value, it indicates that the catalytic purification effect of the catalyst assembly 100 is good, but the odor molecule concentration is high, so more time is needed to catalytically purify the odor molecules in the containing chamber 301. The catalyst assembly 100 is controlled to continue to work until the odor molecule concentration value is less than 10 ppb and the ozone concentration is determined to be less than the first set concentration value, and the catalyst assembly 100 is controlled to stop running after 15 min.

[0094] According to an embodiment of the present application, please refer to Figure 5, before determining the catalyst assembly 100 to start, obtaining the ozone concentration of the containing chamber 301, comprising:

[0095] Step 01: obtaining the humidity of the containing chamber 301;

[0096] Step 02: determining the humidity is less than the set humidity value, controlling the catalyst assembly 100 to start.

[0097] It can be understood that high humidity environment will cause the catalyst assembly 100 to discharge abnormally, and the by-products generated will increase. By setting the humidity sensor 330 to control the catalyst assembly 100 to start, the catalyst assembly 100 can be prevented from running in a high humidity environment. For example, the set humidity value can be 90%, and when the humidity is higher than 90%, the catalyst assembly 100 does not start.

[0098] According to one embodiment of the present application, please refer to Figure 6 (Fan 320 can refer to Figure 16 ), before determining the catalyst assembly 100 to start, obtaining the ozone concentration of the containing chamber 301, comprising:

[0099] Step 03: obtaining the state of the fan 320 of the refrigeration equipment;

[0100] Step 04: determining that the fan 320 is in an open state, controlling the catalyst assembly 100 to start.

[0101] It can be understood that the fan 320 can accelerate air circulation, increase the contact probability of odor molecules and the catalyst assembly 100, help to improve the efficiency of the catalyst, and promote the reaction to proceed. In some embodiments, the fan 320 can supply cooling air flow or hot air to the catalyst assembly 100 when needed to maintain the appropriate temperature and ensure that the catalytic reaction proceeds under optimal temperature conditions.

[0102] In one embodiment, before determining the catalyst assembly 100 to start, obtaining the ozone concentration of the containing chamber 301, the humidity of the containing chamber 301 and the state of the fan 320 of the refrigeration equipment can be obtained. When the humidity is less than the set humidity value and the fan is in an open state, the catalyst assembly 100 is controlled to start.

[0103] It should be noted that the order of the above steps is not limited to the above list unless specifically described or the steps must occur in sequence, and can be changed or rearranged according to the desired design.

[0104] According to the control device of the catalyst assembly 100 of the refrigeration equipment according to the second embodiment of the present application, please refer to Figure 7 , the catalyst assembly 100 comprises:

[0105] The detection module 500 is configured to determine that the catalyst assembly 100 is started, and obtain an ozone concentration of the containing chamber 301, wherein the containing chamber 301 is formed in the refrigeration equipment, and the catalyst assembly 100 is arranged in the containing chamber 301.

[0106] The control module 600 is configured to determine that the ozone concentration is greater than a first set concentration value, control the catalyst assembly 100 to stop, and control the heating element 400 of the catalyst assembly 100 to start, wherein the heating element 400 is configured to heat the catalyst block 1200 of the catalyst assembly 100.

[0107] In one embodiment, please refer to Figure 9 and Figure 10 The catalyst assembly 100 comprises an electrode 1100 and a catalyst block 1200, the electrode 1100 comprises a first electrode sheet 1110 and a second electrode sheet 1120 arranged at intervals, and the first electrode sheet 1110 comprises an electrode tip 1111 arranged towards the second electrode sheet 1120. The catalyst block 1200 is arranged between the first electrode sheet 1110 and the second electrode sheet 1120. An electric field between the electrode tip 1111 and the conductive part 1122 of the second electrode sheet 1120 is less than 1 kilovolt per millimeter.

[0108] According to the catalyst assembly 100 of the present application, the ratio of the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120 and the distance between the electrode tip 1111 and the conductive part 1122 of the second electrode sheet 1120 is less than 1 kilovolt per millimeter, thereby effectively avoiding the discharge abnormality of the catalyst assembly 100 in a humid environment, and the catalyst assembly 100 can meet the disinfection and odor removal requirements in a humid environment.

[0109] It should be noted that the electric field between the electrode tip 1111 and the conductive part 1122 of the second electrode sheet 1120 is less than 1 kilovolt per millimeter, in other words, the ratio of the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120 and the distance between the electrode tip 1111 and the conductive part 1122 of the second electrode sheet 1120 is less than 1 kilovolt per millimeter, wherein the unit of the voltage difference is kilovolt, and the unit of the distance is millimeter.

[0110] It should be noted that in a humid environment, the electrical conductivity of the first electrode sheet 1110 and the second electrode sheet 1120 will increase, causing abnormal flow of current, which may cause problems such as arc discharge. By controlling the distance between the electrode tip 1111 and the second electrode sheet 1120 and the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120, the discharge effect of the catalyst assembly 100 can be controlled.

[0111] It should be noted that based on the principle of high-voltage plasma cooperating with catalysis, the active substances ionized by the electrode tip 1111 can purify the odor in the air, and can also sterilize and disinfect. The catalyst in the catalyst block 1200 can be a manganese-based catalyst, such as an iron-manganese alloy catalyst, a copper-manganese alloy catalyst, etc., or a rare earth catalyst and a noble metal catalyst, or an adsorbent material. Of course, the catalyst in the catalyst block 1200 can be one or a combination of several of the above, as long as it can adsorb impurities and odor molecules in the air.

[0112] The electrode tip 1111 and the second electrode sheet 1120 form a tip discharge effect, and active substances such as plasma, ozone, and negative ions are generated by ionizing the air. The active substances such as plasma, ozone, and negative ions can kill bacteria, and the catalyst block 1200 can adsorb and decompose odor molecules. Then, the ozone can oxidize the odor molecules adsorbed on the catalyst block 1200, so that the active sites of the catalyst block 1200 are released. In other words, the electric field of the electrode tip 1111 can provide active substances for the catalyst block 1200, promote the catalyst to react the odor molecules to generate odorless and harmless gas, and then the catalyst block 1200 can be recycled without the user frequently replacing the catalyst. Moreover, the catalyst block 1200 can also degrade excess ozone to avoid ozone diffusion and affect normal use of the user. The catalyst assembly 100 only needs to use the electrode 1100 and the catalyst block 1200, without the need for additional ozone generators or ultraviolet lamp tubes, which occupies less space while having good sterilization effect.

[0113] Among them, the plasma generated by ionizing the air is a high-temperature, high-energy ionized gas with strong oxidizing and sterilizing ability. It can release a large number of free radicals and electrons to destroy the cell wall and cell membrane of bacteria, thereby killing bacteria. The ozone generated by ionizing the air is a gas with strong oxidizing property, which can further destroy the cell wall and cell membrane of bacteria and inhibit the growth and reproduction of bacteria. The negative ions generated by ionizing the air are air particles with negative charge, which can adsorb and neutralize harmful particles such as bacteria and viruses in the air and make them lose activity.

[0114] The active substances such as plasma, ozone, and negative ions can be adsorbed by the catalyst block 1200. Among them, the ozone and the odor molecules adsorbed by the catalyst block 1200 produce an oxidation reaction, which can oxidize the odor molecules into odorless and harmless compounds. For example, ozone can oxidize sulfides to generate colorless gases such as sulfur dioxide (SO2) and carbon dioxide (CO2). Ozone can also oxidize ammonia (NH3) to generate nitrogen (N2) and water (H2O). Of course, odor molecules are not limited to the above-mentioned sulfides and ammonia, and ozone can also oxidize other odor molecules. Therefore, the active substances generated by ionizing the air can effectively reduce the concentration of odor substances and reduce the intensity of odor, thereby improving air quality.

[0115] The first electrode sheet 1110 can be a positive electrode or a negative electrode. In some applications, the polarity of the first electrode sheet 1110 and the second electrode sheet 1120 can be reversed. For example, the surface of the electrode 1100 can be affected by contamination, corrosion or accumulation, affecting its performance and effectiveness. By reversing the polarity, the electrochemical reaction on the surface of the electrode 1100 can be changed, thereby removing contaminants, corrosion products or repairing the surface of the electrode 1100.

[0116] According to one embodiment of the present application, please refer to Figure 9 The distance between the electrode tip 1111 and the conductive part 1122 of the second electrode sheet 1120 is a first distance 1130, and the distance between the catalyst block 1200 and the conductive part 1122 of the second electrode sheet 1120 is a second distance 1140; the first distance 1130 is less than the second distance 1140. It can be understood that the catalyst block 1200 and the second electrode sheet 1120 are close to increase the contact opportunity of active species generated in the ionization process with the catalyst block 1200, thereby promoting the catalytic oxidation or reduction of pollutants in the air, thereby purifying the air. When ionizing the air, the electrode tip 1111 and the second electrode sheet 1120 are in a high-voltage discharge process, and a plasma channel is formed between the electrode tip 1111 and the second electrode sheet 1120, accompanied by high temperature and strong energy release. If the first distance 1130 is greater than the second distance 1140, the catalyst block 1200 will be too close to the second electrode sheet 1120, which is easy to produce arc. Especially when the catalyst assembly 100 is located in a humid environment, arc discharge is particularly prone to cause the catalyst assembly 100 and the environment where the catalyst assembly 100 is located to be in a dangerous state. By setting the first distance 1130 to be less than the second distance 1140, the second electrode sheet 1120 and the nearest electrode tip 1111 can be ionized, effectively preventing the second electrode sheet 1120 from discharging to the catalyst block 1200.

[0117] In one embodiment, please refer to Figures 8 to 10 The catalyst block 1200 is provided with a heating element 400 for heating the catalyst block 1200 that is frozen or frosted. It can be understood that the freezing or frosting of the catalyst block 1200 will cause the adsorption sites on the catalyst block 1200 to be blocked by ice or frost, resulting in a significant reduction in the catalytic effect of the catalyst block 1200. Heating the catalyst block 1200 with the heating element 400 can release the adsorption sites on the catalyst block 1200, allowing the catalyst block 1200 to maintain high-efficiency catalytic effect.

[0118] In one embodiment, the end surface of the catalyst block 1200 facing the second electrode sheet 1120 can be flat or uneven, in which case the second spacing 1140 can be understood as the shortest distance between the catalyst block 1200 and the plane on which the conductive part 1122 of the second electrode sheet 1120 is located.

[0119] According to one embodiment of the present application, the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120 is 2-10 kilovolts, and the first spacing 1130 is 2-15 mm. For example, when the voltage difference is 2 kilovolts, the first spacing 1130 greater than 2 mm will not cause an electric arc in a humid environment. When the voltage is 10 kilovolts, the first spacing 1130 greater than 10 mm will not cause an electric arc in a humid environment.

[0120] It should be noted that the first spacing 1130 will affect the ionization effect of the catalyst assembly 100 as a whole, and when the first spacing 1130 is much greater than the voltage difference, it will instead result in poor ionization effect. Therefore, when the voltage difference is determined, the first spacing 1130 can be adjusted to be within a suitable range to achieve the best power effect and ensure safety. For example, when the voltage difference is 2 kilovolts, the first spacing 1130 greater than 2 mm and less than 4 mm can achieve a better ionization effect. Of course, the embodiments herein are only examples, and the present application is not limited by the examples herein.

[0121] According to one embodiment of the present application, please refer to Figures 8 to 10 , the first electrode sheet 1110 includes a first electrode plate 1112, and the second electrode sheet 1120 includes a second electrode plate 1121, the first electrode plate 1112 and the second electrode plate 1121 are oppositely arranged; the catalyst block 1200 is provided with a first air hole 1210, the first air hole 1210 is adapted to guide the air flow through the first electrode sheet 1110 to the second electrode sheet 1120 through the catalyst block 1200.

[0122] It can be understood that the oppositely arranged first electrode plate 1112 and second electrode plate 1121 can form a high-voltage electric field, which is applied to the catalyst block 1200. When air enters the high-voltage electric field, it will be ionized to produce active substances. Moreover, the high-voltage electric field and the electric field of the electrode tip 1111 can form a synergistic catalysis to ionize the air flow through the catalyst well.

[0123] It can be understood that the shape of the first air hole 1210 can be any shape, for example, the shape of the first air hole 1210 can be circular, triangular, quadrilateral, pentagonal, hexagonal, or other irregular structures.

[0124] In one embodiment, please refer to Figure 8The first vent holes 1210 are arranged on the catalyst block 1200. The first vent holes 1210 can be uniformly distributed on the catalyst block 1200, for example, a honeycomb structure can be formed. The honeycomb structure has good stability, and thus the catalyst block 1200 has high strength. Of course, the catalyst block 1200 is not limited to the honeycomb structure, and can also be other structures.

[0125] In an embodiment, the first vent holes 1210 close to the electrode tip 1111 have a smaller aperture than the first vent holes 1210 away from the electrode tip 1111. It can be understood that the active substances formed by the electrode tip 1111 ionizing the air will gather near the electrode tip 1111. The smaller the aperture, the more the number of first vent holes 1210 with the same opening area, that is, the higher the density of the first vent holes 1210. In this way, the first vent holes 1210 have a large wall area, and the active substances and odor molecules are more easily adsorbed on the wall, and the adsorption effect of ozone is better. Therefore, a reasonable distribution of the density of the first vent holes 1210 can enable the catalyst block 1200 to effectively adsorb excess ozone, avoiding ozone exceeding the standard (space ozone concentration < 50 ppb).

[0126] In an embodiment, the first electrode plate 1112 and the second electrode plate 1121 are parallel, and the high-voltage electric field formed by the first electrode plate 1112 and the second electrode plate 1121 is uniform. The direction of the hole channel of the first vent hole 1210 is perpendicular to the second electrode plate 1121.

[0127] According to an embodiment of the present application, the first vent holes 1210 are a plurality of, and the conductive part 1122 of the second electrode plate 1121 is provided with a plurality of conductive holes 1123. The closest distance between the electrode tip 1111 and the conductive hole 1123 is the first distance 1130. The electrode tip 1111 points to the conductive hole 1123, and ionization occurs between the electrode tip 1111 and the wall of the conductive hole 1123. The conductive part 1122 provided with a plurality of conductive holes 1123 can make the air pass through the electrode 1100 sheet more uniformly, reducing the problem of dead angle and local airflow. When the air flows through the conductive hole 1123, the electric field and ionization area around the conductive hole 1123 will generate more active substances, which can react with odor molecules to enhance the purification effect. In addition, the electrode 1100 sheet with the conductive hole 1123 is generally lighter, because the conductive hole 1123 reduces the actual mass of the electrode 1100 sheet, which helps to simplify the design and assembly of the device, and reduces the overall weight of the device. In addition, through the conductive hole 1123, it is more convenient to clean and flush the electrode 1100 sheet with cleaning agent or gas. In addition, the conductive hole 1123 can also reduce the accumulation of pollutants on the surface of the electrode 1100, and reduce the difficulty and frequency of cleaning.

[0128] In one embodiment, the conductive hole 1123 is arranged corresponding to the first vent hole 1210, and the shape of the conductive hole 1123 matches the shape of the first vent hole 1210. The matched shape can reduce air resistance and turbulence, and ensure smoother and more uniform air flow inside the catalyst assembly 100, thereby improving the purification effect. In addition, the smoother air flow has less impact on the second electrode sheet 1120, thereby improving the reliability of the second electrode sheet 1120.

[0129] According to one embodiment of the present application, the conductive part 1122 of the second electrode plate 1121 is in a solid structure, and the vertical distance between the electrode tip 1111 and the plane where the solid structure is located is the first spacing 1130. The conductive part 1122 of the solid structure is more solid and stable, reducing the risk of deformation or damage, and helping to ensure the stability and reliability of the catalyst assembly 100 during long-term operation. In addition, the conductive part 1122 of the solid structure can better conduct heat. During discharging, the electrode 1100 sheet can generate heat, and the solid structure can more effectively conduct heat, reducing the formation of hot spots and improving the dispersion of heat, helping to prevent local overheating and thermal damage, and enhancing the durability of the device. Compared with the complex conductive hole 1123 structure, the conductive part 1122 of the solid structure can be easier to manufacture and assemble. The manufacturing process of the conductive part 1122 is relatively simple, and also reduces the difficulty of component handling and installation during assembly, which can reduce manufacturing costs and improve production efficiency.

[0130] According to one embodiment of the present application, the electrode tip 1111 is arranged through the first vent hole 1210. It can be understood that by arranging the electrode tip 1111 through the vent hole of the catalyst block 1200, the contact area between the active substance generated by the electrode tip 1111 and the catalyst can be increased, which can promote more chemical reactions to occur and accelerate the catalytic oxidation or reduction process of odor molecules.

[0131] According to one embodiment of the present application, please refer to Figure 11 , the electrode tip 1111 is arranged outside the catalyst block 1200, and the electrode tip 1111 extends along the hole direction of the first vent hole 1210. It can be understood that the catalyst assembly 100 is easy to be in a humid environment, and arranging the electrode tip 1111 outside the catalyst can avoid condensed water flowing along the electrode tip 1111 into the catalyst block 1200. Taking the case that the catalyst assembly 100 is located in a refrigerator as an example, the catalyst block 1200 is arranged in the air duct 310, and water vapor is generated with each operation of the refrigerator, which will continuously adhere to the catalyst assembly 100. With the refrigeration of the refrigerator, the water vapor will condense into frost, and if the electrode tip 1111 is arranged through the catalyst block 1200, frost will continuously accumulate in the catalyst block 1200, affecting the adsorption of odor molecules by the catalyst block 1200.

[0132] According to an embodiment of the present application, the first electrode plate 1112 and the electrode tip 1111 are integrally formed. The integrally formed design can provide higher structural stability, and the integrally formed structure can simplify the manufacturing and assembly process. Compared with manufacturing the first electrode plate 1112 and the electrode tip 1111 separately and assembling them together, the integrally formed design reduces the bonding process and steps between components, improves manufacturing efficiency and consistency. It can be understood that the first electrode plate 1112 and the electrode tip 1111 can be integrally formed by stamping and bending, so that the structure of the first electrode sheet 1110 is more stable.

[0133] Of course, the first electrode plate 1112 and the electrode tip 1111 are not limited to integrally formed, and the first electrode plate 1112 can be manufactured and assembled separately (for details, please refer to Figure 14 and Figure 15 ), in the case of manufacturing and assembling the first electrode plate 1112 separately, the sterilization and deodorization device can set the number of electrode tips 1111 as needed, without considering the strength problem of the electrode tip 1111, and the electrode tip 1111 can be of different shapes to meet different actual use requirements. For example, mounting holes 1114 can be provided in the conductive area 1113, and the electrode tip 1111 is fixed to the mounting hole 1114 and faces the second electrode sheet 1120. The first electrode plate 1112 can set the number of mounting holes 1114 according to the actual needs of the mounting hole 1114.

[0134] According to an embodiment of the present application, the number of electrode tips 1111 is two, and they are respectively located at both ends of the first electrode plate 1112. The two electrode tips 1111 are respectively located at both ends of the first electrode plate 1112, which does not affect the wind passing through the middle of the catalyst block 1200, reduces the influence on the original air duct 310, and thus ensures the smoothness of the air duct 310. In addition, the electrode tip 1111 located at both ends of the first electrode plate 1112 can ensure the strength of the first electrode sheet 1110. Moreover, placing the electrode tip 1111 at both ends makes the path of high-voltage electricity from the first electrode plate 1112 to the electrode tip 1111 shorter, which can reduce the risk of loss of the first electrode sheet 1110.

[0135] Of course, the electrode tip 1111 can also be multiple, and the present application does not limit the number of electrode tips 1111.

[0136] According to an embodiment of the present application, the electrode tip 1111 is triangular. It can be understood that the triangle can provide the shape of the tip, and the bottom is stable, which ensures the strength of the electrode tip 1111 and facilitates the integrally formed processing of the electrode tip 1111 by stamping and bending.

[0137] According to one embodiment of the present application, the sterilization and deodorization device 200 is provided with the catalyst assembly 100 and a shell 210. The shell 210 is internally formed with a first accommodating cavity 2140, and the catalyst assembly 100 is arranged in the first accommodating cavity 2140. The shell 210 comprises a first shell 2110 and a second shell 2120 which are mutually buckled, and the first shell 2110 and the second shell 2120 form the first accommodating cavity 2140. The first electrode sheet 1110 is connected to the first shell 2110, and the second electrode sheet 1120 is connected to the second shell 2120. Figure 12 and Figure 13 The shell 210 comprises a first shell 2110 and a second shell 2120 which are mutually buckled, and the first shell 2110 and the second shell 2120 form the first accommodating cavity 2140. The first electrode sheet 1110 is connected to the first shell 2110, and the second electrode sheet 1120 is connected to the second shell 2120.

[0138] It can be understood that the first shell 2110 and the second shell 2120 can be arranged along the distribution direction of the catalyst assembly 100, and the first shell 2110 and the second shell 2120 are buckled left and right. Alternatively, the first shell 2110 and the second shell 2120 can be arranged perpendicular to the distribution direction of the catalyst assembly 100, and the first shell 2110 and the second shell 2120 are buckled front and back.

[0139] It should be noted that, since the sterilization and deodorization device 200 comprises the catalyst assembly 100, the content of the first aspect of the present application can be used to explain the sterilization and deodorization device 200 of the second aspect of the present application, and thus the same content will not be described in detail.

[0140] In one embodiment, the position of the first electrode sheet 1110 connected to the first shell 2110 is insulated, and the position of the second electrode sheet 1120 connected to the second shell 2120 is insulated. It can be understood that, in a humid environment, the insulation performance between the first shell 2110 and the connected first electrode sheet 1110 decreases, or the insulation performance between the second shell 2120 and the second electrode sheet 1120 decreases. If the conductive part of the first electrode sheet 1110 contacts the first shell 2110, the sterilization and deodorization device 200 continues to work and is prone to discharge abnormality such as electric arc. By insulating the position of the first electrode sheet 1110 connected to the first shell 2110 and the position of the second electrode sheet 1120 connected to the second shell 2120, the conductive part of the first electrode sheet 1110 and the second electrode sheet 1120 is completely not in contact with the shell 210. Even if the shell and the first electrode sheet 1110 or the second electrode sheet 1120 are wet or covered with ice, the insulation performance of the sterilization and deodorization device 200 will not be reduced, the creepage distance of the voltage is effectively increased, and the sterilization and deodorization device 200 can work in a refrigeration or humid environment without discharge abnormality.

[0141] In one embodiment, please refer to Figure 14 and Figure 15The first electrode plate 1112 is an insulating electrode plate, and a conductive area 1113 is arranged in the middle of one end surface of the first electrode plate 1112. The end of the first electrode plate 1112 provided with the conductive area 1113 faces the second electrode sheet 1120, and the edge of the conductive area 1113 and the edge of the first electrode plate 1112 are both provided with a preset distance 1115.

[0142] The first electrode plate 1112 is an insulating electrode plate, and the conductive area 1113 of the first electrode plate 1112 is prevented from contacting the shell 210 by the preset distance 1115. The conductive area 1113 is arranged in the middle of one end surface of the first electrode plate 1112, and the two end surfaces of the first electrode plate 1112 can be completely insulating end surfaces, thereby reducing the risk of abnormal discharge caused by the contact between the conductive area 1113 and the outside.

[0143] In one embodiment, the conductive area 1113 is formed by printing conductive silver paste. Of course, the present application is not limited by the example, and other methods can also be used to form the conductive area 1113.

[0144] According to one embodiment of the present application, please refer to Figure 15 The preset distance 1115 is 6mm-12mm. It can be understood that when the distance between the conductive area 1113 of the first electrode plate 1112 and the edge of the first electrode plate 1112 is too close, i.e. less than 6mm, the creepage distance of the voltage is not large enough, and arc discharge may occur. By setting the preset distance 1115 in the range of 6mm to 12mm, the risk of arc discharge can be reduced, and the safety and reliability of the circuit can be improved. When the distance between the conductive area 1113 and the first electrode plate 1112 is too far, the same ionization effect is achieved, and the area of the first electrode plate 1112 is larger, which will cause greater resistance to air flow.

[0145] In one embodiment, the preset distance 1115 of the first electrode plate 1112 is provided with 10mm of insulation treatment.

[0146] According to one embodiment of the present application, an insulating member is arranged at the connection between the first shell 2110 and the first electrode sheet 1110, and an insulating member is arranged at the connection between the second shell 2120 and the second electrode sheet 1120, or the contact surface between the first shell 2110 and the first electrode sheet 1110 is sprayed with insulating glue, and the contact surface between the second shell 2120 and the second electrode sheet 1120 is sprayed with insulating glue.

[0147] It can be understood that the insulating member and the insulating glue can form an insulating isolation layer between the electrode 1100 pieces (including the first electrode piece 1110 and the second electrode piece 1120) and the shell (including the first shell 2110 and the second shell 2120), preventing the current from passing through, and helping to prevent the generation of electric arc between the electrode 1100 pieces and the shell, avoiding potential safety risks and equipment failures.

[0148] It can be understood that the insulating member can also provide mechanical support and fixed connection. It can enhance the stability and tightness between the first electrode piece 1110 and the shell, prevent them from loosening or moving, and ensure the reliability and performance of the device.

[0149] In one embodiment, the first electrode piece 1110, the first shell 2110, the second electrode piece 1120, and the second shell 2120 are sprayed with insulating glue or insulating paint at positions where water vapor or ice can contact, to achieve the best insulation effect.

[0150] According to one embodiment of the present application, the first shell 2110 is provided with a first mounting slot 2111 adapted to connect the first electrode piece 1110, and / or the second shell 2120 is provided with a second mounting slot 2121 adapted to connect the second electrode piece 1120. It can be understood that the mounting slots (including the first mounting slot 2111 and the second mounting slot 2121) can provide a stable fixed position, which can ensure that the electrode 1100 pieces (including the first electrode piece 1110 and the second electrode piece 1120) are correctly installed and kept stable, and the first electrode piece 1110 and the second electrode piece 1120 can be kept at a set distance by the mounting slots. The electrode 1100 pieces are installed in the slots, which can prevent them from loosening or shifting. If it is necessary to replace the electrode 1100 pieces, the original electrode 1100 pieces can be removed from the slots and new electrode 1100 pieces can be inserted, without the need for large-scale disassembly of the entire device, and the operator can replace different electrode 1100 pieces as needed.

[0151] According to one embodiment of the present application, the second shell 2120 includes an insulating end plate 2122, and in the case where the second electrode piece 1120 is provided with a conductive hole 1123, the insulating end plate 2122 is provided with a second ventilation hole 2123 corresponding to the conductive hole 1123. It can be understood that the second ventilation hole 2123 is provided in a shape corresponding to the conductive hole 1123, and the second ventilation hole 2123 and the conductive hole 1123 are matched in shape, and the matched shape can reduce air resistance and turbulence, ensuring smoother and more uniform air flow inside the catalyst assembly 100, thereby improving the purification effect. In addition, the smoother air flow has less impact on the second electrode piece 1120, improving the reliability of the second electrode piece 1120. In addition, the insulating end plate 2122 can provide insulation protection to prevent the generation of electric arc between the electrode 1100 pieces and the shell.

[0152] According to an embodiment of the present application, the first shell 2110 and the second shell 2120 are both provided with a protrusion 2124, which is adapted to limit the catalyst block 1200. It can be understood that, by limiting the catalyst block 1200, the movement, swing or deviation of the catalyst block 1200 from a predetermined position can be prevented, so as to ensure that the catalyst block 1200 remains stable during the operation of the catalyst assembly 100, and the catalyst block 1200 and the first shell 2110 and the second shell 2120 can be kept at a set distance, which can ensure the effective reaction of the catalyst block 1200, help to improve the efficiency and catalytic effect of the catalyst block 1200, and enhance the performance and purification effect of the device.

[0153] According to an embodiment of the present application, the protrusion 2124 of at least one of the first shell 2110 and the second shell 2120 is provided in a sawtooth shape. It can be understood that the sawtooth-shaped protrusion 2124 can increase the contact area between the shell (including the first shell 2110 and the second shell 2120) and the catalyst block 1200, so that the contact between the limiting block and the catalyst block 1200 is more close and stable, thereby increasing the limiting effect.

[0154] In an embodiment, the sawtooth-shaped protrusion 2124 can be inserted into the first ventilation hole 1210 of the catalyst block 1200, further enhancing the limiting effect of the catalyst block 1200.

[0155] According to an embodiment of the present application, the sterilization and deodorization device 200 comprises a power supply 220, which is electrically connected with the first electrode sheet 1110 and the second electrode sheet 1120; the shell 210 comprises a third shell 2130, which is connected with the buckled first shell 2110 and the second shell 2120, and forms a second accommodating cavity 2150, and the power supply 220 is arranged in the second accommodating cavity 2150. It can be understood that the power supply 220 is used to supply power to the first electrode sheet 1110 and the second electrode sheet 1120. As an example, the working voltage range of the high-voltage power supply 220 used in the present embodiment is 2-10 kilovolts.

[0156] It should be noted that the first accommodating cavity 2140 is suitable for placing the catalyst assembly 100, and the second accommodating cavity 2150 is suitable for placing the power supply 220; thus, the first shell 2110 and the second shell 2120 are buckled to each other to form an independent air duct 310 structure, and the power supply 220 arranged in the second accommodating cavity 2150 will not affect the air flow of the first accommodating cavity 2140, so that the air can pass through the catalyst assembly 100 with the maximum air volume, and the catalytic performance and effect are ensured. In addition, the catalyst assembly 100 and the power supply 220 are arranged in different accommodating cavities, so that the power supply 220 can be prevented from being affected by an electric field, and the performance and service life of the power supply 220 are affected. The active substances generated by ionization can also be prevented from affecting the normal use of the power supply 220. Therefore, the electrolyte solution of the power supply 220 and the gas generated by discharging are arranged in different cavities, so that the mutual interference and influence of the two can be effectively avoided.

[0157] According to one embodiment of the present application, a limiting protrusion 2151 is arranged on the cavity wall of the second accommodating cavity 2150, and the power supply 220 is connected to the limiting protrusion 2151, and the limiting protrusion 2151 is suitable for maintaining a gap between the power supply 220 and the cavity wall of the second accommodating cavity 2150.

[0158] It can be understood that the gap between the power supply 220 and the cavity wall of the second accommodating cavity 2150 can reduce the influence of the humid or icy environment on the first shell 2110, the second shell 2120 and the third shell 2130 on the power supply 220, and the performance and service life of the power supply 220 are protected.

[0159] According to one embodiment of the present application, the limiting protrusion 2151 comprises a support strip, a positioning groove is arranged on the support strip, the positioning groove has a preset interval with the cavity wall where the support strip is located, and the power supply 220 is connected to the positioning groove.

[0160] It can be understood that the side wall of the positioning groove and the side wall of the second accommodating cavity 2150 have a preset interval, and the bottom of the positioning groove and the bottom wall of the second accommodating cavity 2150 have a preset interval, so that the power supply 220 is connected to the positioning groove, and the gap between the power supply 220 and the cavity wall of the second accommodating cavity 2150 is maintained. In addition, the positioning groove can also limit the power supply 220, so that the power supply 220 can be kept stable during the working process of the catalyst assembly 100.

[0161] In one embodiment, the preset interval is 3 mm. The power supply 220 can maintain the best working state during the working process of the sterilizing and deodorizing device. Of course, the present application is not limited to the embodiment, and the preset interval can also be other.

[0162] It should be noted that the present application does not limit the shape of the positioning groove, as long as the power supply 220 can maintain a gap with the cavity wall of the second accommodating cavity 2150.

[0163] The refrigeration device according to the third aspect of the present application comprises a body 300, a catalyst assembly 100, an ozone sensor 340 and a controller. The body 300 is internally formed with a containing chamber 301, the catalyst assembly 100 is arranged in the containing chamber 301, the ozone sensor 340 is used to obtain the ozone concentration of the containing chamber 301, and the controller is connected to the ozone sensor 340 and the catalyst assembly 100 and is used to execute the control method of the catalyst assembly 100 of the refrigeration device as described above. It should be noted that the content of the first aspect of the present application can be used to explain the storage cabinet of the third aspect, and thus the same content will not be described in detail.

[0164] It can be understood that the containing chamber 301 of the refrigerator can comprise a refrigeration chamber and a freezing chamber. The refrigeration chamber can be used to preserve food materials, for example, fresh vegetables and fruits. The freezing chamber can be used to freeze and store food materials, such as meat. Since the freezing chamber and the refrigeration chamber in the containing chamber 301 are in communication with each other, the gas in the containing chamber 301 can freely diffuse, and the gas comprises odor molecules which can cause odor cross-contamination between food materials stored at different positions. Therefore, by arranging the catalyst assembly 100, the odor molecules can be purified, the influence of odor cross-contamination can be reduced, and the user experience can be improved. The air blown into the catalyst assembly 100 can be treated by means of the air duct 310 of the body 300 or the air speed of the air outlet of the air duct 310, so as to ensure that the air entering the containing chamber 301 is odorless and solve the ice hygiene and odor problems.

[0165] Under the guidance of the fan 320 in the air duct 310, the airflow flows from the second electrode sheet 1120 to the first electrode sheet 1110. The odor molecules first pass through the electrode tip 1111 of the first electrode sheet 1110. The active substances generated by the electrode tip 1111 can purify and disinfect a part of the odor molecules. The remaining odor molecules are adsorbed by the catalyst block 1200. At the same time, the active substances generated by the electrode tip 1111 react with the adsorbed odor molecules to decompose the odor molecules. Not only can the adsorption catalyst sites of the catalyst block 1200 be released, but also the concentration of ozone can be reduced to prevent ozone from exceeding the standard.
