Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a control method and a control device for a catalyst component of a refrigeration device. Background Art

[0002] At present, users are paying more and more attention to the sanitation of refrigeration equipment. Taking refrigerators as an example, the freezer compartment and ice-making compartment of refrigerators usually share a large freezing space and air duct. The freezer compartment usually contains ingredients with odor properties such as seafood, meat, etc., while the ice box is used to store ice cubes. Since the freezer compartment and the ice box share an air duct, it is easy to cause ice cubes to have a cross-flavor phenomenon; at the same time, if the cold storage compartment, the freezer compartment and the ice-making compartment also share an air duct, the odor molecules generated by the odor ingredients such as durian, onion, kimchi, leftovers, etc. placed in the cold storage compartment will enter the freezer compartment and then enter the ice-making compartment, thereby causing the odor of ice cubes and easily breeding bacteria. It is necessary to sterilize and disinfect the refrigeration equipment and purify the taste. However, the surface of the existing catalyst assembly used for sterilization, disinfection and purification of refrigeration equipment is prone to ice or frost, and ice or frost will block the adsorption site of the catalyst assembly, greatly reducing the adsorption effect of the catalyst assembly.

[0070] A refrigeration device is a device for cooling or lowering temperature. The refrigeration device may be a refrigerator or freezer for storing and preserving food and other perishable items, and the present invention is not particularly limited thereto. In order to more specifically describe the control method of the catalyst assembly 100 of the refrigeration device of the present invention, the following description will be based on the use scenario of the refrigeration device being a refrigerator.

[0071] According to the control method of the catalyst assembly 100 of the refrigeration equipment of the first embodiment of the present invention, please refer to Figure 1 (The catalyst assembly 100 and the heating element 400 can refer to Figures 8 to 10 , the containing chamber 301 and the ozone sensor 340 can refer to Fig.16 ), the control method of the catalyst assembly 100 of the refrigeration equipment includes:

[0072] Step 10: Determine that the catalyst assembly 100 is started, and obtain the ozone concentration in the receiving chamber 301 , wherein the receiving chamber 301 is formed inside the refrigeration equipment, and the catalyst assembly 100 is disposed in the receiving chamber 301 .

[0073] Step 20 : 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 used to heat the catalyst block 1200 of the catalyst assembly 100 .

[0074] According to the control method of the catalyst assembly 100 of the refrigeration equipment of the embodiment of the present invention, the catalyst block 1200 is heated by the heating element 400, so that the ice or frost attached to the catalyst block 1200 can be turned into water or steam and leave the catalyst block 1200, thereby releasing the adsorption sites on the catalyst block 1200 again. The adsorption sites on the catalyst block 1200 will not be blocked by ice or frost, so that the catalyst block 1200 can maintain a high catalytic effect.

[0075] In step 10, the ozone concentration of the receiving chamber 301 can be obtained by the ozone sensor 340. The ozone sensor 340 can be set at multiple locations of the receiving chamber 301, and can fully monitor the ozone level of the entire receiving chamber 301 to ensure that the obtained ozone concentration is more accurate.

[0076] In step 20, the first set concentration value can be set to 50ppb (parts per billion). It is understandable that ozone is a highly oxidizing gas that can have an adverse effect on food at high concentrations. When food is exposed to a high concentration of ozone, ozone may react with nutrients and odor molecules in the food, causing the food to deteriorate and deteriorate in quality. When the catalyst assembly 100 is started, it is detected whether the ozone concentration exceeds 50ppb. When the ozone concentration is greater than 50ppb, the catalyst assembly 100 is controlled to stop to prevent the ozone concentration from becoming a new source of odor in the containing chamber 301. Of course, the first set concentration value can also be other, and the present invention is not limited to the embodiments herein.

[0077] In step 20, the catalyst block 1200 is used to adsorb odor molecules in the accommodation space, and the odor molecules here also include ozone generated by the catalyst assembly 100 ionizing the air. When the catalyst assembly 100 is arranged in the refrigeration equipment, especially when the catalyst assembly 100 is arranged in the accommodation space of the refrigerator, each operation of the refrigerator will generate water vapor, and the water vapor will continue to adhere to the catalyst assembly 100. As the refrigerator is refrigerated, the water vapor will condense into frost, which will cause the catalyst block 1200 to continuously accumulate frost, blocking the adsorption position of the catalyst block 1200 to the odor molecules, and affecting the adsorption of the catalyst block 1200 to the odor molecules. The heating element 400 can heat and heat the catalyst block 1200, melt the ice attached to the catalyst block 1200, release the adsorption position on the catalyst block 1200, and thus restore the catalytic effect of the catalyst assembly 100. The heating element 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 invention, please refer to Figure 2 (The heating element 400 can refer to Figure 8 ), the step 20 of controlling the heating element 400 of the catalyst assembly 100 to start, comprises:

[0079] Step 21: Obtain the working status of the refrigeration circuit of the refrigeration equipment;

[0080] Step 22: Determine that the refrigeration circuit is not in a refrigeration state, and control the heating element 400 to operate.

[0081] In step 22, the refrigeration circuit is not in the refrigeration state, which means that the refrigeration circuit needs to be switched to a state in order to maintain and optimize the performance of the equipment except that the refrigeration circuit is in the refrigeration state. For example, not being in the refrigeration state includes:

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

[0083] Defrosting state: In some cases, ice will accumulate on the surface of the evaporator, affecting its normal operation. In order to remove the ice, the refrigeration equipment will enter the defrosting state. In this state, the compressor may stop running, and other components (such as heaters) will provide heat to melt the ice. For example, when the refrigeration equipment is a direct cooling refrigerator, the refrigeration cycle system directly delivers the refrigerant to the surface of the evaporator in the refrigerator. When the moisture in the air contacts the evaporator, it condenses into water droplets and freezes to form an ice layer, which requires regular defrosting operations to maintain its normal working effect. Therefore, when the refrigerator is in the defrosting state, the heating element 400 is also turned on to defrost the catalyst block 1200 to avoid unnecessary energy consumption.

[0084] According to an embodiment of the present invention, please refer to Figure 3 (The odor sensor 350 and the receiving chamber 301 can refer to Fig.16 ), the control method of the catalyst assembly 100 of the refrigeration equipment further includes:

[0085] Step 30: Obtaining the concentration of odor molecules in the containing chamber 301;

[0086] Step 40: Determine that the concentration of odor molecules 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 time.

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

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

[0089] If it is determined that the concentration value of odor molecules is less than 10ppb but the ozone concentration is greater than the first set concentration value, it means that the catalytic purification efficiency of the catalyst assembly 100 is weak. There may be a layer of ice or frost on the catalyst block 1200 that blocks the adsorption position of the catalyst block 1200. The catalyst block 1200 needs to be heated by the heating element 400 to release the adsorption position of the catalyst block 1200 and restore the original catalytic purification efficiency. Before starting the heating element 400, it is necessary to first determine that the refrigeration circuit is not 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 continues to heat for 10 minutes to restore the original adsorption effect of the catalyst assembly 100. If the refrigeration circuit is in a refrigeration state, stop the operation of the catalyst assembly 100 to prevent the catalyst assembly 100 from continuing to produce ozone, causing ozone to become a new source of odor.

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

[0091] Step 30: Obtaining the concentration of odor molecules in the containing chamber 301;

[0092] Step 50: Determine that the concentration of odor molecules is greater than the second set concentration value, determine that the ozone concentration is less than the first set concentration value, and control the catalyst assembly 100 to continue working.

[0093] In step 50, the second set concentration value can be set to 10ppb. For example, if it is determined that the odor molecule concentration value is greater than 10ppb and the ozone concentration is less than the first set concentration value, it means 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, and the catalyst assembly 100 is controlled to continue working until the odor molecule concentration value is less than 10ppb 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 minutes.

[0094] According to an embodiment of the present invention, please refer to Figure 5Before determining that the catalyst assembly 100 is started and obtaining the ozone concentration in the containing chamber 301, the steps include:

[0095] Step 01: Obtain the humidity of the receiving chamber 301;

[0096] Step 02: Determine that the humidity is less than the set humidity value, and control the catalyst assembly 100 to start.

[0097] It is understandable that a high humidity environment will cause abnormal discharge of the catalyst assembly 100 and increase the amount of byproducts produced. By setting a humidity sensor 330 to control the start of the catalyst assembly 100, the catalyst assembly 100 can be prevented from operating in a high humidity environment. For example, the humidity value can be set to 90%, and the catalyst assembly 100 will not start when the humidity is higher than 90%.

[0098] According to an embodiment of the present invention, please refer to Figure 6 (For fan 320, please refer to Fig.16 ), before determining that the catalyst assembly 100 is started and obtaining the ozone concentration in the containing chamber 301, including:

[0099] Step 03: Obtain the status of the fan 320 of the refrigeration equipment;

[0100] Step 04: Determine that the fan 320 is in the on state, and control the catalyst assembly 100 to start.

[0101] It is understandable that the fan 320 can accelerate air circulation, increase the contact probability between odor molecules and the catalyst assembly 100, help improve the efficiency of the catalyst, and promote the reaction. In some embodiments, the fan 320 can supply cooling airflow or hot air to the catalyst assembly 100 when necessary to maintain an appropriate temperature to ensure that the catalytic reaction is carried out under optimal temperature conditions.

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

[0103] It should be noted that, unless specifically described or steps must occur in sequence, the order of the above steps is not limited to that listed above 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 of the second embodiment of the present invention, please refer to Figure 7 , the catalyst assembly 100 comprises:

[0105] The detection module 500 is used to determine whether the catalyst assembly 100 is started and obtain the ozone concentration in the receiving chamber 301, wherein the receiving chamber 301 is formed inside the refrigeration equipment and the catalyst assembly 100 is disposed in the receiving chamber 301;

[0106] The control module 600 is used 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 used to heat the catalyst block 1200 of the catalyst assembly 100.

[0107] In one embodiment, please refer to Fig. 9 and Fig.10 The catalyst assembly 100 includes: an electrode 1100 and a catalyst block 1200. The electrode 1100 includes a first electrode sheet 1110 and a second electrode sheet 1120 arranged at intervals. The first electrode sheet 1110 includes an electrode tip 1111 arranged toward the second electrode sheet 1120. The catalyst block 1200 is arranged between the first electrode sheet 1110 and the second electrode sheet 1120. The electric field between the electrode tip 1111 and the conductive portion 1122 of the second electrode sheet 1120 is less than 1 kV / mm.

[0108] According to the catalyst assembly 100 of the present invention, the distance between the electrode tip 1111 and the conductive portion 1122 of the second electrode sheet 1120, and the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120 satisfy that the ratio of the voltage difference value to the distance between the electrode tip 1111 and the conductive portion 1122 of the second electrode sheet 1120 is less than 1 kV / mm, thereby effectively avoiding the defect of abnormal discharge of the catalyst assembly 100 in a humid environment, and the catalyst assembly 100 can meet the requirements of disinfection and deodorization in a humid environment.

[0109] It should be noted that the electric field between the electrode tip 1111 and the conductive portion 1122 of the second electrode sheet 1120 is less than 1 kilovolt / millimeter. In other words, the ratio of the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120 to the distance between the electrode tip 1111 and the conductive portion 1122 of the second electrode sheet 1120 is less than 1, where 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 conductivity of the first electrode sheet 1110 and the second electrode sheet 1120 will increase, resulting in abnormal current flow, which may cause abnormal discharge and arcing. 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-pressure plasma synergistic catalysis, the active substances generated by the ionization of the electrode tip 1111 can purify odors in the air and can also sterilize and disinfect. The catalyst in the catalyst block 1200 can be a manganese catalyst, such as an iron-manganese alloy catalyst, a copper-manganese alloy catalyst, etc., or a rare earth catalyst and a precious metal catalyst, or an adsorption material. Of course, the catalyst in the catalyst block 1200 can be one or a combination of the above, as long as it can adsorb impurities and odor molecules in the air.

[0112] A tip discharge effect is formed between the electrode tip 1111 and the second electrode sheet 1120, which ionizes the air to produce active substances such as plasma, ozone, and negative ions. Active substances such as plasma, ozone, and negative ions can kill bacteria, and the catalyst block 1200 can adsorb and decompose odor molecules, and then ozone can oxidize the odor molecules adsorbed on the catalyst block 1200, thereby releasing the active sites of the catalyst block 1200. 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 gases, and then the catalyst block 1200 can be recycled without the user frequently replacing the catalyst. In addition, the catalyst block 1200 can also degrade excess ozone to avoid ozone diffusion and affect the normal use of the user. The catalyst assembly 100 only needs to use the electrode 1100 and the catalyst block 1200, without the need to set up an ozone generator or ultraviolet lamp, and has a good sterilization effect while occupying a small space.

[0113] Among them, the plasma produced by ionized air is a high-temperature, high-energy ionized gas with strong oxidizing and bactericidal capabilities. It can release a large number of free radicals and electrons to destroy the bacterial cell walls and cell membranes, thereby killing the bacteria. The ozone produced by ionized air is a highly oxidizing gas that can further destroy the bacterial cell walls and cell membranes and inhibit the growth and reproduction of bacteria. The negative ions produced by ionized air are negatively charged air particles that can adsorb and neutralize harmful particles such as bacteria and viruses in the air and make them inactive.

[0114] Active substances such as plasma, ozone, and negative ions can be adsorbed by the catalyst block 1200. Among them, 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 produce colorless gases such as sulfur dioxide (SO2) and carbon dioxide (CO2). Ozone can also oxidize ammonia (NH3) to produce 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 produced by ionized air can effectively reduce the concentration of odor substances and reduce the intensity of odors, thereby improving air quality.

[0115] The first electrode sheet 1110 can be a positive electrode or a negative electrode. In a specific application scenario, the polarity of the first electrode sheet 1110 and the second electrode sheet 1120 may be reversed. For example, the surface of the electrode 1100 may be affected by contamination, corrosion or accumulation, affecting its performance and effect. 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 an embodiment of the present invention, please refer to Fig. 9 , the distance between the electrode tip 1111 and the conductive part 1122 of the second electrode sheet 1120 is a first spacing 1130, and the distance between the catalyst block 1200 and the conductive part 1122 of the second electrode sheet 1120 is a second spacing 1140; the first spacing 1130 is smaller than the second spacing 1140. It can be understood that the catalyst block 1200 and the second electrode sheet 1120 are close to each other in order to increase the contact opportunity between the active species generated during the ionization process and the catalyst block 1200, thereby promoting catalytic oxidation or reduction reactions 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 spacing 1130 is greater than the second spacing 1140, then the catalyst block 1200 will be too close to the second electrode sheet 1120, which is prone to arcing. Especially when the catalyst assembly 100 is located in a humid environment, arc discharge is particularly likely to cause the catalyst assembly 100 and the environment in which the catalyst assembly 100 is located to be in a dangerous state. By setting the first spacing 1130 to be smaller than the second spacing 1140, it is possible to ensure that the second electrode sheet 1120 and the nearest electrode tip 1111 are 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, and the heating element 400 is used to heat the catalyst block 1200 that is iced or frosted. It is understandable that ice or frosting on 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. The heating element 400 heats the catalyst block 1200 to release the adsorption sites on the catalyst block 1200, allowing the catalyst block 1200 to maintain an efficient catalytic effect.

[0118] In one embodiment, the end surface of the catalyst block 1200 facing the second electrode sheet 1120 may be flat or uneven, and the second interval 1140 may be understood as the shortest distance between the catalyst block 1200 and the plane where the conductive portion 1122 of the second electrode sheet 1120 is located.

[0119] According to one embodiment of the present invention, the voltage difference between the first electrode sheet 1110 and the second electrode sheet 1120 is 2 kV-10 kV, and the first spacing 1130 is 2 mm-15 mm. For example, when the voltage difference is 2 kV, the first spacing 1130 is greater than 2 mm and arcs will not be generated in a humid environment. When the voltage is 10 kV, the first spacing 1130 is greater than 10 mm and arcs will not be generated in a humid environment.

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

[0121] According to an embodiment of the present invention, 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 arranged opposite to each other. The catalyst block 1200 is provided with a first ventilation hole 1210. The first ventilation hole 1210 is suitable for guiding the airflow flowing through the first electrode sheet 1110 to the second electrode sheet 1120 through the catalyst block 1200.

[0122] It is understandable that the first electrode plate 1112 and the second electrode plate 1121 are arranged relative to each other to form a high-voltage electric field. When the high-voltage electric field is applied to the catalyst block 1200, air entering the high-voltage electric field will be ionized to generate active substances. In addition, the high-voltage electric field and the electric field of the electrode tip 1111 can form a synergistic catalysis, so that the air fluid flowing through the catalyst has a good ionization effect.

[0123] It is understandable that the shape of the first ventilation hole 1210 can be any shape. For example, the shape of the first ventilation hole 1210 can be circular, triangular, quadrilateral, pentagonal, hexagonal or other special-shaped structures.

[0124] In one embodiment, please refer to Figure 8The catalyst block 1200 is provided with a plurality of first ventilation holes 1210, which can be evenly distributed in the catalyst block 1200, for example, a honeycomb structure can be formed, and 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 one embodiment, the aperture of the first ventilation hole 1210 near the electrode tip 1111 is smaller than the aperture of the first ventilation hole 1210 far from the electrode tip 1111. It is understandable that the active substances formed by the ionization of air by the electrode tip 1111 will gather in large quantities near the electrode tip 1111. The smaller the aperture, the more first ventilation holes 1210 with the same opening area, that is, the density of the first ventilation holes 1210 is higher. In this way, the pore wall area of ​​the first ventilation holes 1210 is large, and the active substances and odor molecules are more easily adsorbed onto the pore wall, which has a better adsorption effect on ozone. Therefore, the reasonable distribution of the density of the first ventilation holes 1210 can allow the catalyst block 1200 to effectively adsorb excess ozone and avoid excessive ozone (spatial ozone concentration <50ppb).

[0126] In one 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 has a uniform field strength. The first ventilation hole 1210 is perpendicular to the second electrode plate 1121 .

[0127] According to one embodiment of the present invention, there are multiple first ventilation holes 1210, and the conductive part 1122 of the second electrode plate 1121 is provided with multiple conductive holes 1123, and the closest distance between the electrode tip 1111 and the conductive hole 1123 is the first spacing 1130. The electrode tip 1111 points to the conductive hole 1123, and ionization is generated between the electrode tip 1111 and the hole wall of the conductive hole 1123. The conductive part 1122 is provided with multiple conductive holes 1123 to allow air to pass through the electrode 1100 more evenly, reducing the problem of dead corners and local airflow problems. When air flows through the conductive holes 1123, the electric field and ionization area around the conductive holes 1123 will produce more active substances, which can react with odor molecules to enhance the purification effect. In addition, the electrode 1100 with the conductive hole 1123 is usually lighter, because the conductive hole 1123 reduces the actual mass of the electrode 1100, which helps to simplify the design and assembly of the device and reduce the overall weight of the device. In addition, the conductive holes 1123 can more conveniently pass cleaning agents or gases through the electrode 1100 for cleaning and flushing. In addition, the conductive holes 1123 can also reduce the accumulation of pollutants on the surface of the electrode 1100, reducing the difficulty and frequency of cleaning.

[0128] In one embodiment, the conductive hole 1123 is arranged corresponding to the first ventilation hole 1210, and the shape of the conductive hole 1123 matches the shape of the first ventilation hole 1210. The matching shapes can reduce air resistance and turbulence, ensuring that the air flows more smoothly and evenly inside the catalyst assembly 100, thereby improving the purification effect. In addition, the air flows more smoothly, and the impact force on the second electrode sheet 1120 is smaller, thereby improving the reliability of the second electrode sheet 1120.

[0129] According to one embodiment of the present invention, the conductive portion 1122 of the second electrode plate 1121 is a solid structure, and the vertical distance between the electrode tip 1111 and the plane where the solid structure is located is a first spacing 1130. The conductive portion 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 portion 1122 of the solid structure can better conduct heat. During the discharge process, the electrode 1100 may generate heat, and the solid structure can conduct heat more effectively, reduce the formation of hot spots and improve the dispersion of heat, help prevent local overheating and thermal damage, and enhance the durability of the device. Compared with the complex conductive hole 1123 structure, the conductive portion 1122 of the solid structure may be easier to manufacture and assemble. The manufacturing process of the conductive portion 1122 is relatively simple, and the difficulty of component handling and installation during assembly is also reduced, which can reduce manufacturing costs and improve production efficiency.

[0130] According to one embodiment of the present invention, the electrode tip 1111 is inserted into the first ventilation hole 1210. It is understandable that by inserting the electrode tip 1111 into the ventilation 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 and accelerate the catalytic oxidation or reduction process of odor molecules.

[0131] According to an embodiment of the present invention, please refer to Fig.11 , the electrode tip 1111 is arranged outside the catalyst block 1200, and the electrode tip 1111 extends along the channel direction of the first ventilation hole 1210. It is understandable that the catalyst assembly 100 is easily in a humid environment, and the electrode tip 1111 is arranged outside the catalyst to prevent condensed water from flowing along the electrode tip 1111 into the catalyst block 1200. Taking the catalyst assembly 100 in a refrigerator as an example, the catalyst block 1200 is arranged in the air duct 310, and each operation of the refrigerator will generate water vapor, which will continuously adhere to the catalyst assembly 100, and as the refrigerator cools, the water vapor will condense into frost. If the electrode tip 1111 is inserted into the catalyst block 1200, it will cause the catalyst block 1200 to continuously accumulate frost, affecting the adsorption of odor molecules by the catalyst block 1200.

[0132] According to one embodiment of the present invention, 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 and assembling the first electrode plate 1112 and the electrode tip 1111 separately, the integrally formed design reduces the joining process and steps between the components, and improves the manufacturing efficiency and consistency. It is understandable 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 being integrally formed, and the first electrode plate 1112 may also be manufactured separately and assembled together (for details, please refer to Fig.14 and Fig.15 ), when the first electrode plates 1112 are manufactured and assembled separately, the number of electrode tips 1111 can be set as needed in the sterilizer, without considering the strength of the electrode tips 1111, and the electrode tips 1111 can be structures of different shapes to meet different needs of actual use. For example, a mounting hole 1114 can be set 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 number of mounting holes 1114 can be set according to the actual needs of the first electrode plate 1112.

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

[0135] Of course, there may be multiple electrode tips 1111 , and the present invention does not limit the number of electrode tips 1111 .

[0136] According to one embodiment of the present invention, the electrode tip 1111 is a triangle. It is understandable that the triangle can provide a tip shape and a stable bottom, thereby ensuring the strength of the electrode tip 1111 and facilitating the integrated forming of the electrode tip 1111 by stamping and bending.

[0137] According to an embodiment of the present invention, a deodorizer 200 is provided. Fig.12 and Fig.13 The deodorizer 200 includes: the above-mentioned catalyst assembly 100 and a shell 210; a first accommodating chamber 2140 is formed inside the shell 210, and the catalyst assembly 100 is arranged in the first accommodating chamber 2140; the shell 210 includes a first shell 2110 and a second shell 2120 that are interlocked, and the first shell 2110 and the second shell 2120 form a first accommodating chamber 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 is understandable that the first housing 2110 and the second housing 2120 can be arranged along the distribution direction of the catalyst assembly 100, and the first housing 2110 and the second housing 2120 can be buckled left and right. It can also be arranged perpendicular to the distribution direction of the catalyst assembly 100, and the first housing 2110 and the second housing 2120 can be buckled front and back.

[0139] It should be noted that, since the deodorizer 200 includes the above-mentioned catalyst assembly 100, the contents of the first embodiment of the present invention can be used to explain the deodorizer 200 of the second embodiment, and therefore the same contents will not be repeated.

[0140] In one embodiment, the position of the first electrode sheet 1110 connected to the first housing 2110 is insulated; the second electrode sheet 1120 is connected to the housing 210, and the position of the second electrode sheet 1120 connected to the second housing 2120 is insulated. It is understandable that in a humid environment, the insulation performance of the first housing 2110 and the connected first electrode sheet 1110 is reduced, or the insulation performance between the second housing 2120 and the second electrode sheet 1120 is reduced. If the conductive part of the first electrode sheet 1110 contacts the first housing 2110, the disinfection and deodorization device 200 will continue to work and it will be easy to cause abnormal discharge problems such as arcing. By insulating the position where the first electrode sheet 1110 is connected to the first shell 2110, and insulating the position where the second electrode sheet 1120 is connected to the second shell 2120, the conductive parts of the first electrode sheet 1110 and the second electrode sheet 1120 are completely out of contact with the shell 210. Even if the shell and the first electrode sheet 1110 or the second electrode sheet 1120 are stained with water or ice, the insulation performance of the disinfection and deodorization device 200 will not be reduced, and the creepage distance of the voltage is effectively increased, so that the disinfection and deodorization device 200 can work in a freezing or humid environment without abnormal discharge.

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

[0142] The first electrode plate 1112 is an insulated electrode plate, and by setting a preset distance 1115, the conductive region 1113 of the first electrode plate 1112 will not contact the housing 210. The conductive region 1113 is provided 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 insulated end surfaces, thereby reducing the risk of abnormal discharge caused by the conductive region 1113 contacting the outside world.

[0143] In one embodiment, the conductive region 1113 is formed by printing a conductive silver paste. Of course, the present invention is not limited to the example given here, and the conductive region 1113 can also be formed by other methods.

[0144] According to an embodiment of the present invention, please refer to Fig.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, that is, when it is less than 6mm, the creepage distance of the voltage is not large enough and arc discharge may occur. By setting the preset distance 1115 within 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, to achieve the same ionization effect, the area of ​​the first electrode plate 1112 is larger, which will produce greater resistance to air circulation.

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

[0146] According to one embodiment of the present invention, an insulating part is provided at the connection between the first shell 2110 and the first electrode sheet 1110, and an insulating part is provided 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 parts and insulating glue can form an insulating isolation layer between the electrode 1100 sheet (including the first electrode sheet 1110 and the second electrode sheet 1120) and the outer shell (including the first outer shell 2110 and the second outer shell 2120), blocking the passage of current, helping to prevent the formation of arcs between the electrode 1100 sheet and the outer shell, and avoiding potential safety risks and equipment failures.

[0148] It is understood that the insulating member can also provide mechanical support and fixed connection, which can enhance the stability and tightness between the first electrode sheet 1110 and the housing, prevent loosening or movement between them, and ensure the reliability and performance of the device.

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

[0150] According to one embodiment of the present invention, the first housing 2110 is provided with a first mounting groove 2111, and the first mounting groove 2111 is suitable for connecting the first electrode sheet 1110, and / or, the second housing 2120 is provided with a second mounting groove 2121, and the second mounting groove 2121 is suitable for connecting the second electrode sheet 1120. It is understood that the mounting groove (including the first mounting groove 2111 and the second mounting groove 2121) can provide a stable fixed position, which can ensure that the electrode 1100 sheets (including the first electrode sheet 1110 and the second electrode sheet 1120) are properly installed and remain stable, and the first electrode sheet 1110 and the second electrode sheet 1120 can maintain a set spacing through the mounting groove. The electrode 1100 sheets are installed in the groove to prevent them from loosening or offset. If the electrode 1100 sheets need to be replaced, only the original electrode 1100 sheets need to be removed from the groove and a new electrode 1100 sheets need to be inserted, without large-scale disassembly of the entire device, and the operator can replace different electrodes 1100 sheets as needed.

[0151] According to one embodiment of the present invention, the second housing 2120 includes an insulating end plate 2122. When the second electrode sheet 1120 is provided with a conductive hole 1123, the insulating end plate 2122 is provided with a second vent 2123 corresponding to the conductive hole 1123. It is understandable that the second vent 2123 corresponds to the shape of the conductive hole 1123, and the shape of the second vent 2123 and the conductive hole 1123 match. The matching shape can reduce air resistance and turbulence, ensuring that the air flows more smoothly and evenly inside the catalyst assembly 100, thereby improving the purification effect. In addition, the air flows more smoothly, and the impact force on the second electrode sheet 1120 is smaller, which improves the reliability of the second electrode sheet 1120. In addition, the insulating end plate 2122 can provide insulation protection to prevent arcing between the electrode 1100 sheet and the housing.

[0152] According to one embodiment of the present invention, both the first housing 2110 and the second housing 2120 are provided with a boss 2124, and the boss 2124 is suitable for limiting the catalyst block 1200. It is understandable that by limiting the catalyst block 1200, the catalyst block 1200 can be prevented from moving, swinging or deviating from the predetermined position, thereby ensuring that the catalyst block 1200 remains stable during the operation of the catalyst assembly 100, and the catalyst block 1200 and the first housing 2110 and the second housing 2120 maintain a set distance, which can ensure the effective reaction of the catalyst block 1200, help improve the efficiency and catalytic effect of the catalyst block 1200, and enhance the performance and purification effect of the device.

[0153] According to one embodiment of the present invention, the boss 2124 of at least one of the first shell 2110 and the second shell 2120 is configured to be serrated. It is understandable that the serrated boss 2124 can increase the contact area between the shell (including the first shell 2110 and the second shell 2120) and the catalyst block 1200, making the contact between the limit block and the catalyst block 1200 more compact and stable, thereby increasing the limit effect.

[0154] In one embodiment, the sawtooth-shaped boss 2124 may be inserted into the first ventilation hole 1210 of the catalyst block 1200 , further enhancing the limiting effect on the catalyst block 1200 .

[0155] According to one embodiment of the present invention, the deodorizer 200 includes a power supply 220, which is electrically connected to the first electrode sheet 1110 and the second electrode sheet 1120; the housing 210 includes a third housing 2130, which is connected to the first housing 2110 and the second housing 2120 that are buckled together, and forms a second accommodating cavity 2150, and the power supply 220 is disposed 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 operating voltage range of the high-voltage power supply 220 used in this embodiment is 2 kilovolts to 10 kilovolts.

[0156] It should be noted that the first accommodating chamber 2140 is suitable for placing the catalyst assembly 100, and the second accommodating chamber 2150 is suitable for placing the power supply 220; thus, the first housing 2110 and the second housing 2120 are interlocked to form an independent air duct 310 structure, and the power supply 220 is arranged in the second accommodating chamber 2150 without affecting the wind flow of the first accommodating chamber 2140, ensuring that the air can pass through the catalyst assembly 100 with the maximum wind volume, ensuring the catalytic performance and effect. In addition, the catalyst assembly 100 and the power supply 220 are respectively located in different accommodating chambers to prevent the power supply 220 from being affected by the electric field, affecting the performance and life of the power supply 220. It can also prevent the active substances generated by ionization from affecting the normal use of the power supply 220. Therefore, placing the electrolyte solution of the power supply 220 and the gas generated by the discharge separately in different chambers can effectively avoid mutual interference and influence between the two.

[0157] According to one embodiment of the present invention, a limiting protrusion 2151 is provided on the cavity wall of the second accommodating cavity 2150 , 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 is understandable that maintaining a gap between the power supply 220 and the cavity wall of the second accommodating cavity 2150 can reduce the impact of the first shell 2110, the second shell 2120 and the third shell 2130 in a humid or icy environment on the power supply 220, thereby protecting the performance and life of the power supply 220.

[0159] According to an embodiment of the present invention, the limiting protrusion 2151 includes a support bar, a positioning groove is provided on the support bar, a preset distance is provided between the positioning groove and the cavity wall where the support bar is located, and the power supply 220 is connected to the positioning groove.

[0160] It can be understood that there is a preset distance between the side wall of the positioning groove and the side wall of the second accommodating chamber 2150, and there is a preset distance between the bottom of the positioning groove and the bottom wall of the second accommodating chamber 2150, so that the power supply 220 is connected to the positioning groove, and there is a gap between the power supply 220 and the cavity wall of the second accommodating chamber 2150. In addition, the positioning groove can also limit the power supply 220, so as to ensure that the power supply 220 remains stable during the operation of the catalyst assembly 100.

[0161] In one embodiment, the preset spacing is 3 mm. The power supply 220 can maintain an optimal working state during the operation of the sterilizing and purifying device. Of course, the present invention is not limited to the embodiments herein, and the preset spacing can also be other.

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

[0163] The refrigeration equipment according to the third aspect of the present invention includes a body 300, a catalyst assembly 100, an ozone sensor 340 and a controller. A receiving chamber 301 is formed inside the body 300, the catalyst assembly 100 is arranged in the receiving chamber 301, the ozone sensor 340 is used to obtain the ozone concentration in the receiving 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 equipment mentioned above. It should be noted that the contents of the first aspect of the present invention can be used to explain the storage cabinet of the third aspect of the present invention, so the same contents will not be repeated.

[0164] It is understandable that the storage compartment 301 of the refrigerator may include a refrigerating compartment and a freezing compartment, and the refrigerating compartment may be used to keep food fresh, for example, it may be used to store fresh fruits and vegetables. The freezing compartment may be used to freeze food and store meat. Since the freezing compartment and the refrigerating compartment in the storage compartment 301 are interconnected, the gas in the storage compartment 301 can diffuse freely, and the gas includes odor molecules, which may cause the food stored in different positions to have a cross-flavor. Therefore, by setting the catalyst assembly 100, the odor molecules can be purified, the influence of cross-flavor can be reduced, and the user experience can be improved. The air blown into the catalyst assembly 100 can be processed by the wind speed of the air duct 310 or the air outlet of the air duct 310 of the body 300 to ensure that the wind entering the storage compartment 301 has no odor, and the problem of ice hygiene and odor can be solved.

[0165] Through the guiding effect of the fan 320 in the air duct 310, the air flow flows from the second electrode sheet 1120 to the first electrode sheet 1110, and the odor molecules first pass through the electrode tip 1111 of the first electrode sheet 1110. The active substance produced by the electrode tip 1111 can purify a part of the odor molecules and disinfect them, and the remaining odor molecules are adsorbed by the catalyst block 1200. At the same time, the ozone of the active substance produced by the electrode tip 1111 reacts with the adsorbed odor molecules to decompose the odor molecules, which can not only release the adsorption catalytic sites of the catalyst block 1200, but also reduce the concentration of ozone to prevent ozone from exceeding the standard.
