[0083] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0084] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0085] The hydrogen peroxide generator and its applications will be described in detail below through specific embodiments:

[0086] Reference Figures 1 to 5 ,as well as Figures 13 to 19 As shown in some embodiments of this disclosure, a hydrogen peroxide generator 10 is provided, including a housing 11 and an inlet 17 and an outlet 18 disposed on the housing 11. The inlet 17 is used to connect to a water supply component. The housing 11 is provided with a cathode plate 12 and an anode plate 13 for electrolyzing water to generate hydrogen peroxide solution. The outlet 18 is used to discharge the generated hydrogen peroxide solution.

[0087] In other words, water from the water supply component enters the housing 11 through the inlet 17, and is electrolyzed into hydrogen peroxide by the cathode plate 12 and anode plate 13 inside the housing 11. The hydrogen peroxide solution produced by electrolysis is discharged from the housing 11 through the outlet 18. Hydrogen peroxide solution has good cleaning, deodorizing, disinfecting, and sterilizing functions. Therefore, when this hydrogen peroxide generator 10 is applied to household appliances (such as laundry equipment, clothing processing equipment, dishwashers, refrigerators, air conditioners, dehumidifiers, etc.), it can play a good role in cleaning, deodorizing, disinfecting, and sterilizing.

[0088] Specifically, when the hydrogen peroxide generator 10 is applied to washing equipment (such as washing machines and dishwashers), it can clean the clothes to be washed with reduced or even no detergent, enhance the washing effect, reduce detergent usage, achieve low carbon and environmental protection, and eliminate the need for users to frequently add detergent to the washing chamber. When the hydrogen peroxide generator 10 is applied to other household appliances (such as dryers, clothes care cabinets, refrigerators, air conditioners, dehumidifiers, etc.), it can effectively remove odors, ensure air cleanliness, and thus improve the user experience.

[0089] In specific implementation, the hydrogen peroxide generator 10 is installed in a household appliance. The inlet 17 and outlet 18 of the hydrogen peroxide generator 10 can be connected to the liquid pipeline already present in the household appliance, or to a liquid pipeline additionally installed in the household appliance for connecting the hydrogen peroxide generator 10. The inlet 17 of the hydrogen peroxide generator 10 can also be at least partially immersed in the washing water, thereby realizing the generation of hydrogen peroxide solution by electrolyzing water using the hydrogen peroxide generator 10. This achieves the purpose of using the hydrogen peroxide solution to enhance the cleaning ability of household appliances such as washing equipment, as well as the deodorizing, disinfecting, sterilizing, and purifying effects on household appliances such as dryers, care cabinets, refrigerators, air conditioners, and humidifiers.

[0090] In some embodiments, refer to Figures 1 to 5 As shown, the housing 11 includes a first housing portion 111 and a second housing portion 113 connected to each other. An electrolysis chamber is formed between the first housing portion 111 and the second housing portion 113. A housing frame 114 is disposed in the electrolysis chamber. The cathode plate 12 is disposed between the first housing portion 111 and the housing frame 114, and the anode plate 13 is disposed between the second housing portion 113 and the housing frame 114. That is, the housing frame 114 is disposed between the cathode plate 12 and the anode plate 13, so that there is a certain distance between the cathode plate 12 and the anode plate 13. This arrangement allows water to enter between the cathode plate 12 and the anode plate 13, thereby ensuring that both the cathode plate 12 and the anode plate 13 can contact water, thus ensuring the electrolysis effect of the hydrogen peroxide generator 10.

[0091] In some embodiments, refer to Figures 1 to 4 As shown, the first housing part 111 and the second housing part 113 are fixed together by a snap-fit ​​mechanism to form an electrolytic cavity between them. Of course, the fixing method between the first housing part 111 and the second housing part 113 can also be a threaded connection, magnetic fixation, etc. This disclosure does not limit this, as long as it can fix the first housing part 111 and the second housing part 113 together and form an electrolytic cavity between them.

[0092] In some embodiments, refer to Figure 5 As shown, in order to ensure the sealing of the electrolytic cavity formed between the first housing part 111 and the second housing part 113, a sealing ring 19 is provided at the periphery where the first housing part 111 and the second housing part 113 are connected, so as to achieve a sealed connection between the first housing part 111 and the second housing part 113 through the sealing ring 19.

[0093] For ease of installation, please refer to... Figure 5As shown, the first housing portion 111 can be a housing structure with a cavity, that is, the first housing portion 111 can include a bottom wall and a surrounding wall connected to the periphery of the bottom wall, the bottom wall and the surrounding wall together forming a housing structure with one open end; correspondingly, the second housing portion 113 can be a cover structure, that is, the second housing portion 113 is a cover structure covering the open end of the first housing portion 111, and the surrounding wall of the first housing portion 111 and the periphery of the first housing portion 111 are provided with a snap-fit ​​structure to achieve a fixed connection between the first housing portion 111 and the second housing portion 113. Of course, the first housing portion 111 and the second housing portion 113 can both be housing structures with cavities, the openings of the cavities of the first housing portion 111 and the second housing portion 113 facing each other, together forming an electrolytic chamber for holding liquid.

[0094] In some embodiments, refer to Figure 5 As shown, both the inlet 17 and the outlet 18 are located on the inner frame 114 of the housing, with an inlet pipe connected to the inlet 17 and an outlet pipe connected to the outlet 18. Specifically, the inlet pipe can be connected to a water supply component to supply water required for electrolysis to the housing 11, and the outlet pipe can be connected to a desired location such as the chamber of a household appliance to supply hydrogen peroxide solution generated by electrolysis to the desired location such as the chamber of the household appliance. In some embodiments, one of the first housing portion 111 and the second housing portion 113 is provided with a first clearance hole for the inlet pipe to extend out, and the other of the first housing portion 111 and the second housing portion 113 is provided with a second clearance hole for the outlet pipe to extend out, so that the inlet pipe and the outlet pipe can extend from the electrolysis chamber of the hydrogen peroxide generator 10 to communicate with external components.

[0095] In specific implementations, the inlet 17 and outlet 18 can be located on two opposite sidewalls of the housing frame 114. In some embodiments, the inlet 17 and outlet 18 can be located diagonally on two opposite sidewalls of the housing frame 114 to ensure sufficient distance between them, allowing water entering through the inlet 17 to be fully electrolyzed in the electrolysis chamber before being discharged through the outlet 18. Of course, the inlet 17 and outlet 18 can also be located on the same sidewall of the housing frame 114 as needed. The inlet 17 and outlet 18 can also be located on the first housing portion 111 or the second housing portion 113 as needed, as long as they can supply water to the electrolysis chamber and discharge the hydrogen peroxide solution generated in the electrolysis chamber.

[0096] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the first housing portion 111 is provided with a perforated hole 112 communicating with the outside air. The perforated hole 112 is located on the side of the first housing portion 111 facing away from the housing frame 114. The side of the cathode plate 12 facing away from the housing frame 114 is in contact with the outside air through the perforated hole 112. This arrangement allows one surface of the cathode plate 12 to be in contact with air, while the other surface is in contact with water in the electrolysis chamber, thereby ensuring the electrolysis effect. In some embodiments, a first sealing gasket 15 is provided between the side of the cathode plate 12 facing away from the housing frame 114 and the inner wall surface of the first housing portion 111. The first sealing gasket 15 is located in the peripheral area of ​​the perforated hole 112. This arrangement isolates the outside air from the electrolysis chamber, preventing the liquid in the electrolysis chamber from leaking out through the perforated hole 112 provided on the first housing portion 111.

[0097] In specific implementations, the cathode plate 12 can adopt a flat plate structure, that is, a non-perforated or non-opening plate structure, so as to isolate the liquid in the electrolysis chamber from the outside air through the cathode plate 12. Of course, in specific implementations, the cathode plate 12 may not be in direct contact with the outside air. In this case, the perforated hole 112 may not be provided on the first housing part 111. Correspondingly, the cathode plate 12 may also adopt a mesh or porous structure.

[0098] In some embodiments, refer to Figure 5 As shown, the hydrogen peroxide generator 10 also includes an ion exchange membrane 14, which is disposed between the cathode plate 12 and the anode plate 13, and divides the internal space of the housing 11 into a cathode cavity and an anode cavity. In other words, the ion exchange membrane 14 separates the electrolysis chamber formed within the housing 11 into a cathode cavity and an anode cavity. The ion exchange membrane 14 is used to accelerate the exchange rate of ions generated during electrolysis, thereby improving electrolysis efficiency. Simultaneously, the ion exchange membrane 14 can separate the hydrogen peroxide generated by the cathode plate 12 from the anode plate 13, preventing the hydrogen peroxide from being oxidized by the anode plate 13 and affecting the electrolysis efficiency.

[0099] In some embodiments, refer to Figure 5 As shown, second sealing gaskets 16 are provided between the outer periphery of the ion exchange membrane 14 facing the cathode plate 12 and the cathode plate 12, and between the outer periphery of the ion exchange membrane 14 facing the anode plate 13 and the anode plate 13. The second sealing gaskets 16 improve the sealing performance of the cathode cavity and the anode cavity to ensure the electrolysis effect.

[0100] In one specific embodiment, refer to Figure 5As shown, a housing frame 114 is also provided between the cathode plate 12 and the anode plate 13. In order to ensure the sealing effect, a second sealing gasket 16 can be provided between the outer area of ​​the anode plate 13 and the second housing part 113, between the outer area of ​​the ion exchange membrane 14 and the housing frame 114, and between the outer area of ​​the cathode plate 12 and the housing frame 114.

[0101] For example, refer to Figure 5 As shown, the hydrogen peroxide generator 10 includes a first housing portion 111 and a second housing portion 113 connected to each other. An electrolysis chamber is formed between the first housing portion 111 and the second housing portion 113, and a sealing ring 19 is provided at the periphery connection of the first housing portion 111 and the second housing portion 113. Along the direction from the first housing portion 111 to the second housing portion 113, a first sealing gasket 15, a cathode plate 12, a second sealing gasket 16, a housing frame 114, a second sealing gasket 16, an ion exchange membrane 14, a second sealing gasket 16, an anode plate 13, and a second sealing gasket 16 are sequentially arranged in the electrolysis chamber.

[0102] In some embodiments, the first housing portion 111 has a cavity with an opening facing the second housing portion 113, and positioning posts extending toward the second housing portion 113 are respectively provided at the four corners of the cavity of the first housing portion 111. The first sealing gasket 15, cathode plate 12, second sealing gasket 16, housing frame 114, second sealing gasket 16, ion exchange membrane 14, second sealing gasket 16, anode plate 13 and second sealing gasket 16 are sequentially passed through the positioning posts.

[0103] In some embodiments, to simultaneously supply water to the cathode and anode chambers via the inlet pipe, a distributor pipe communicating with the inlet pipe can be provided on the housing frame 114. The distributor pipe passes through the ion exchange membrane 14 to supply water to the anode chamber. Correspondingly, to simultaneously discharge liquid from the cathode and anode chambers via the outlet pipe, a manifold pipe communicating with the outlet pipe can be provided on the housing frame 114. The manifold pipe passes through the ion exchange membrane 14 to collect liquid from the anode chamber and channel it to the outlet pipe.

[0104] In some embodiments, refer to Figure 5 As shown, the cathode plate 12 has a flat plate structure to isolate the external air and the electrolytic chamber. Specifically, the cathode plate 12 includes a first metal substrate and a conductive carbon substrate layer coated on the surface of the first metal substrate. The first metal substrate can be selected from any one or a combination of at least two of platinum mesh, nickel mesh, or stainless steel mesh, and the conductive carbon substrate layer is composed of carbon materials, preferably carbon black or carbon-doped materials.

[0105] In a practical implementation, a conductive carbon-based material can be coated onto the surface of a first metal substrate and pressed to form a three-phase gas diffusion electrode. The gas diffusion electrode possesses highly efficient gas molecule transport channels and abundant hydrogen peroxide reaction sites. Oxygen molecules in the air pass through the electrode and gain electrons on the other side to produce hydrogen peroxide. Specifically, the cathode chemical reaction is: O2 + 2H2O + 4e- → 2H2O2. Therefore, the cathode 12 needs to be in contact with air on one side and with the electrolyte on the other.

[0106] In some embodiments, refer to Figure 5 As shown, the anode plate 13 has a flat plate structure, a mesh structure, or a porous structure. Specifically, the anode plate 13 includes a second metal substrate and a transition metal coating with catalytic activity coated on the surface of the second metal substrate. The second metal substrate is made of any one or a combination of at least two of titanium, nickel, or platinum, and the transition metal coating is composed of any one or a combination of at least two of ruthenium, iridium, tantalum, palladium, or their oxides. For example, refer to... Figure 5 As shown, the anode plate 13 has a porous structure, wherein the shape of the pores can be any shape, such as circular, square, or irregular, and the number can be specifically set according to actual needs; this disclosure does not limit this. Specifically, the thickness of the anode plate 13 is not less than 0.5 mm. The anode chemical reaction formula is: 4OH-→O2+2H2O+4e-.

[0107] It is understandable that when the anode plate 13 is a flat plate structure, the electrolysis chamber is a cavity structure formed between the cathode plate 12 and the anode plate 13. When the anode plate 13 is a mesh plate structure or a porous structure, the electrolysis chamber is a cavity structure formed between the cathode plate 12 and the second housing part 113. Water can pass through the anode plate 13 and flow in the electrolysis chamber, thereby ensuring that the shape of the anode plate 13 can be specifically set according to actual needs.

[0108] It should be noted that, in specific implementation, both the anode plate 13 and the cathode plate 12 need to be connected to a DC power supply. The DC power supply is placed outside the housing 11 of the hydrogen peroxide generator 10 so as to provide electron supply to the anode plate 13 and the cathode plate 12 through the DC power supply, and the current is controlled between 0-10A.

[0109] In other embodiments, reference is made to Figures 13 to 19As shown, the housing 11 includes a first housing portion 111 and a second housing portion 113 connected to each other. An electrolysis chamber is formed between the first housing portion 111 and the second housing portion 113. A first cathode plate 121, an anode plate 13, and a second cathode plate 122 are sequentially and spaced apart in the electrolysis chamber along the direction from the first housing portion 111 to the second housing portion 113. Both the liquid inlet 17 and the liquid outlet 18 are connected to the electrolysis chamber. This arrangement ensures that there is a certain distance between the first cathode plate 121 and the anode plate 13, and a certain distance between the second cathode plate 122 and the anode plate 13, guaranteeing that the first cathode plate 121, the second cathode plate 122, and the anode plate 13 can all contact the water entering the electrolysis chamber, thereby ensuring the electrolysis effect of the hydrogen peroxide generator 10. Furthermore, by providing two cathode plates and one anode plate, the electrolysis efficiency of the hydrogen peroxide generator 10 can be better guaranteed compared to providing only one cathode plate and one anode plate.

[0110] It should be noted that the number of cathode and anode plates disposed within the housing 11 is not limited to one; two, three, or more can be disposed as needed. For example, in... Figures 1 to 5 In the illustrated embodiment, a cathode plate 12 and an anode plate 13 are disposed within the housing 11 of the hydrogen peroxide generator 10; in such a way... Figures 13 to 19 In the embodiment shown, the housing 11 of the hydrogen peroxide generator 10 is provided with two cathode plates and one anode plate 13, and the two cathode plates are the first cathode plate 121 and the second cathode plate 122, respectively.

[0111] In some embodiments, refer to Figure 14 , Figure 15 , Figure 16 and Figure 19 As shown, the first housing portion 111 is provided with a first perforation 1111 communicating with the outside air. The side of the first cathode plate 121 facing away from the anode plate 13 is in contact with the outside air through the first perforation 1111. A first sealing gasket 191 is provided between the side of the first cathode plate 121 facing away from the anode plate 13 and the inner wall surface of the first housing portion 111. The first sealing gasket 191 is located in the outer area of ​​the first perforation 1111. This arrangement allows one side of the first cathode plate 121 to be in contact with air, while the other side is in contact with the water in the electrolysis chamber, thereby ensuring the electrolysis effect. Furthermore, by providing the first sealing gasket 191, the outside air is isolated from the electrolysis chamber, preventing the liquid in the electrolysis chamber from leaking out through the first perforation 1111 provided on the first housing portion 111.

[0112] In some embodiments, refer to Figure 13 , Figure 16 and Figure 19As shown, the second housing portion 113 is provided with a second perforation 1131 communicating with the outside air. The side of the second cathode plate 122 facing away from the anode plate 13 is in contact with the outside air through the second perforation 1131. A second sealing gasket 192 is provided between the side of the second cathode plate 122 facing away from the anode plate 13 and the inner wall surface of the second housing portion 113. The second sealing gasket 192 is located in the outer area of ​​the second perforation 1131. This arrangement allows one side of the second cathode plate 122 to be in contact with air, while the other side is in contact with the water in the electrolysis chamber, thereby ensuring the electrolysis effect. Furthermore, by providing the second sealing gasket 192, the outside air is isolated from the electrolysis chamber, preventing the liquid in the electrolysis chamber from leaking out through the second perforation 1131 provided on the second housing portion 113.

[0113] In some embodiments, refer to Figure 16 and Figure 19 As shown, a first spacer 193 is provided between the first cathode plate 121 and the anode plate 13 to separate them. A second spacer 194 is provided between the second cathode plate 122 and the anode plate 13 to separate them. This arrangement ensures that the first cathode plate 121, the second cathode plate 122, and the anode plate 13 can all come into contact with the water entering the electrolysis chamber, thereby ensuring the electrolysis effect of the hydrogen peroxide generator 10.

[0114] Specifically, refer to Figure 19 As shown, the first spacer 193 may include two first spacer strips, both located between the first cathode plate 121 and the anode plate 13, and disposed opposite to each other at their edges; the second spacer 194 may include two second spacer strips, both located between the second cathode plate 122 and the anode plate 13, and disposed opposite to each other at their edges. Of course, both the first spacer 193 and the second spacer 194 may also be rectangular structures, as long as they can effectively separate the cathode plate and the anode plate 13.

[0115] In some embodiments, refer to Figure 16 and Figure 19As shown, a receiving groove 1112 is formed on the first housing portion 111, with its opening facing the second housing portion 113. The first cathode plate 121, the anode plate 13, and the second cathode plate 122 are sequentially arranged in the receiving groove 1112. The second housing portion 113 covers the opening of the receiving groove 1112 to form an electrolysis chamber. A mounting groove 1113 is provided on the first housing portion 111, surrounding the receiving groove 1112. A third sealing gasket 195 is provided in the mounting groove 1113. The side of the second housing portion 113 facing the first housing portion 111 abuts against the third sealing gasket 195. This arrangement facilitates the installation of the first cathode plate 121, the anode plate 13, and the second cathode plate 122 in the electrolysis chamber and ensures the sealing of the electrolysis chamber.

[0116] Specifically, to ensure the reliability of the seal, refer to Figure 16 As shown, a protrusion corresponding to the mounting groove 1113 can be provided on the side of the second housing portion 113 facing the first housing portion 111. When the second housing portion 113 is installed on the first housing portion 111, the protrusion applies a compressive force to the third sealing gasket 195 in the mounting groove 1113, thereby ensuring the firmness of the seal between the first housing portion 111 and the second housing portion 113.

[0117] In some embodiments, refer to Figures 13 to 15 , Figure 17 and Figure 18 As shown, the first housing portion 111 has two opposing sidewalls, with an inlet 17 and an outlet 18 respectively disposed on the two opposing sidewalls of the first housing portion 111. This arrangement ensures sufficient distance between the inlet 17 and the outlet 18, allowing water entering through the inlet 17 to be fully electrolyzed in the electrolysis chamber before being discharged through the outlet 18. Of course, the inlet 17 and the outlet 18 can also be disposed on the same sidewall of the first housing portion 111 as needed, as long as it enables the supply of water to the electrolysis chamber and the discharge of the hydrogen peroxide solution generated in the electrolysis chamber.

[0118] In some embodiments, refer to Figure 17 and Figure 18As shown, with the direction from the first housing portion 111 towards the second housing portion 113 as the height direction, the height of the outlet 18 is higher than that of the inlet 17 in the vertical direction shown in the figure. That is, by setting the inlet 17 at a relatively low position and the outlet 18 at a relatively high position, water can smoothly enter the electrolysis chamber through the inlet 17 while preventing the water entering the electrolysis chamber from being quickly discharged through the outlet 18. This ensures that the water entering the electrolysis chamber can stay in the electrolysis chamber for a longer period of time and that the water can fully contact the first cathode plate 121 and the second cathode plate 122 to ensure the electrolysis effect. Of course, the relative height of the inlet 17 and the outlet 18 is not limited to the above limitation and can be reasonably set according to actual needs.

[0119] In some embodiments, refer to Figure 19 As shown, an inlet chamber 1114 and an outlet chamber 1115 are formed between the first housing portion 111 and the second housing portion 113. The inlet chamber 1114 and the outlet chamber 1115 are located on both sides of the electrolysis chamber. The inlet port 17 is connected to the electrolysis chamber through the inlet chamber 1114, and the electrolysis chamber is connected to the outlet port 18 through the outlet chamber 1115. That is, water first enters the inlet chamber 1114 through the inlet port 17, and then enters the electrolysis chamber through the inlet chamber 1114. By setting the inlet chamber 1114, a certain amount of water can be stored, thereby ensuring the efficiency of water supply to the electrolysis chamber. The hydrogen peroxide solution generated by electrolysis in the electrolysis chamber first enters the outlet chamber 1115, and then is discharged through the outlet port 18.

[0120] In some embodiments, refer to Figure 13 and Figure 19 As shown, each of the first cathode plate 121, the anode plate 13, and the second cathode plate 122 is provided with an electrical connection piece 131. The housing has an installation port, and a sealing cover 196 is installed at the installation port. The sealing cover 196 has an installation socket through which the power supply connection piece 131 passes. It should be understood that the first cathode plate 121, the second cathode plate 122, and the anode plate 13 all need to be connected to a DC power supply. The DC power supply is located outside the housing of the hydrogen peroxide generator 10. This arrangement connects the first cathode plate 121, the second cathode plate 122, and the anode plate 13 to an external power supply, providing an electron supply to them via DC power. Specifically, the current can be controlled between 0-10A.

[0121] In a specific implementation, an installation notch communicating with the groove of the receiving groove 1112 can be opened on the side wall of the first housing part 111. After the second housing part 113 is placed on the first housing part 111, the installation notch is sealed, so that the first housing part 111 and the second housing part 113 together form an installation opening. In specific installation, the sealing cap 196 can be installed at the installation notch first, and then the second housing part 113 can be placed on the first housing part 111.

[0122] In some embodiments, refer to Figures 13 to 16 , Figure 19 As shown, a first mounting portion is provided around the periphery of the first housing portion 111, and a second mounting portion corresponding to the first mounting portion is provided around the periphery of the second housing portion 113. The first housing portion 111 and the second housing portion 113 are fixedly connected by fasteners 197 passing through the first mounting portion and the second mounting portion. Specifically, both the first mounting portion and the second mounting portion can be screw posts, and the fasteners 197 can be screws, so that the installation and fixation between the first housing portion 111 and the second housing portion 113 can be achieved by screws. The structure is simple and the assembly is convenient.

[0123] In some embodiments, refer to Figure 13 , Figure 14 , Figure 19 As shown, at least one of the first housing portion 111 and the second housing portion 113 is provided with a third mounting portion 1116 on the side facing away from the other, so as to fix the hydrogen peroxide generator 10 to the electrical appliance by fasteners passing through the third mounting portion 1116.

[0124] Specifically, the third mounting part 1116 may be provided on only one of the first housing part 111 and the second housing part 113, or the third mounting part 1116 may be provided on both of them, so as to ensure the reliability of the fixation between the hydrogen peroxide generator 10 and the electrical components.

[0125] It should be noted that the fixing method between the first housing part 111 and the second housing part 113 is not limited to screw connection, but can also be achieved by means of snap fasteners; the fixing method between the hydrogen peroxide generator 10 and the electrical appliance is not limited to screw connection, but can also be achieved by means of snap fasteners.

[0126] Other embodiments of this disclosure provide a laundry washing device 20, including a laundry treatment chamber 21, a water inlet passage 22, and a hydrogen peroxide generator 10. The water inlet passage 22 is connected to the laundry treatment chamber 21 and can supply washing water to the laundry treatment chamber 21 through the water inlet passage 22. The hydrogen peroxide generator 10 is disposed on the water inlet passage 22 or in the laundry treatment chamber 21. The hydrogen peroxide generator 10 is used to electrolyze water to generate a hydrogen peroxide solution to supply the hydrogen peroxide solution to the laundry treatment chamber 21.

[0127] Specifically, when the hydrogen peroxide generator 10 is installed on the water inlet channel 22, the hydrogen peroxide generator 10 can directly utilize the water in the water inlet channel 22 to perform electrolysis, and the hydrogen peroxide solution generated by electrolysis is transported to the clothes processing chamber 21 through the water inlet channel 22, thereby improving the cleaning ability of the clothes washing equipment 20 without the need for multiple additions of detergent; when the hydrogen peroxide generator 10 is installed inside the clothes processing chamber 21, the hydrogen peroxide generator 10 can directly utilize the water in the clothes processing chamber 21 to perform electrolysis and generate a hydrogen peroxide solution for washing clothes. Specifically, the clothes washing equipment 20 can be a drum washing machine, see reference. Figure 6 As shown; the laundry equipment 20 can also be a top-loading washing machine, see reference. Figure 7 As shown; of course, the laundry washing device 20 can also be other devices for washing clothes, and this disclosure does not limit it.

[0128] It should be noted that the clothes handling chamber refers to the cavity used to handle clothes. In a washing machine, taking a front-loading washing machine as an example, the space enclosed by the clothes handling tub, the door, and the door seal ring forms the clothes handling chamber; in a dryer, the dryer's drum assembly forms the clothes handling chamber.

[0129] In some embodiments, the hydrogen peroxide generator 10 includes a housing 11 and an inlet 17 and an outlet 18 disposed on the housing 11. The housing 11 contains a cathode plate 12 and an anode plate 13 for electrolyzing water to generate a hydrogen peroxide solution. When the hydrogen peroxide generator 10 is disposed on the water inlet channel 22, the inlet 17 is connected to the inlet of the water inlet channel 22, and the outlet 18 is connected to the outlet of the water inlet channel 22; alternatively, the inlet 17 is connected to the water inlet channel 22, and the outlet 18 is connected to the laundry processing chamber 21. This configuration improves the cleaning capacity of the laundry equipment 20 without requiring multiple additions of detergent. Specifically, the water inlet channel 22 may include a first water inlet pipe section and a second water inlet pipe section, with the hydrogen peroxide generator 10 connected between the first and second water inlet pipe sections. Alternatively, the water inlet channel 22 may consist of only one water inlet section, with the hydrogen peroxide generator 10 connected to either the inlet or outlet of the water inlet channel 22.

[0130] In some embodiments, refer to Figures 20 to 25 As shown, the water inlet path 22 includes a first water inlet branch 221 and a second water inlet branch 222. Both the first water inlet branch 221 and the second water inlet branch 222 are connected to the laundry processing chamber 21. The hydrogen peroxide generator 10 is installed on one of the first water inlet branch 221 and the second water inlet branch 222. That is, the laundry washing equipment 20 has at least two water inlet branches that supply water to the laundry processing chamber 21 respectively, and the hydrogen peroxide generator 10 is installed on one of the water inlet branches.

[0131] With this configuration, when the hydrogen peroxide generator 10 is needed, one of the water inlet branches equipped with the hydrogen peroxide generator 10 can be controlled to supply water to the laundry treatment chamber 21. The hydrogen peroxide generator 10 then electrolyzes the water supplied by the inlet branch to generate a hydrogen peroxide solution, which enters the laundry treatment chamber 21 to clean, deodorize, disinfect, and sterilize the clothes inside. When the hydrogen peroxide generator 10 is not needed, one of the water inlet branches without the hydrogen peroxide generator 10 can be controlled to supply water to the laundry treatment chamber 21, maintaining the original washing function of the laundry equipment. Of course, it is also feasible to only set up one water inlet branch 22 and install the hydrogen peroxide generator 10 on the water inlet branch 22.

[0132] It should be noted that the water inlet path 22 is not limited to including two water inlet branches. It can also be set with three or more water inlet branches as needed, and the hydrogen peroxide generator 10 is set on one of the water inlet branches.

[0133] For example, refer to Figures 20 to 22 As shown, the water inlet path 22 includes three water inlet branches, namely the first water inlet branch 221, the second water inlet branch 222 and the third water inlet branch 223. The first water inlet branch 221, the second water inlet branch 222 and the third water inlet branch 223 are all connected to the inner cavity of the clothing processing chamber 21. The hydrogen peroxide generator 10 is installed on the second water inlet branch 222.

[0134] In some embodiments, refer to Figures 23 to 25 As shown, the laundry equipment includes a dispensing component 23, which is connected between the water inlet channel 22 and the laundry processing chamber 21. A hydrogen peroxide generator 10 is disposed outside the dispensing component 23 and connected to it.

[0135] Specifically, the dispensing component 23 has a detergent dispensing port and is connected between the water inlet channel 22 and the laundry processing chamber 21. Detergent is dispensed into the dispensing component 23 through the detergent dispensing port, and water is supplied to the dispensing component 23 through the water inlet channel 22 to rinse the detergent in the dispensing component 23, thus dispensing the detergent from the dispensing component 23 into the laundry processing chamber 21. By placing the hydrogen peroxide generator 10 outside the dispensing component 23 and connecting it to the dispensing component 23, compared to installing the hydrogen peroxide generator 10 inside the laundry processing chamber 21, on the one hand, it makes the installation and fixation of the hydrogen peroxide generator 10 more convenient, and on the other hand, it facilitates the connection of the hydrogen peroxide generator 10 to the water inlet channel 22.

[0136] Taking a drum washing machine as an example, a drum washing machine typically includes a cabinet and a drum assembly 24 disposed inside the cabinet. The drum assembly 24 may specifically include an outer drum and an inner drum disposed inside the outer drum. The dispensing component 23 may be disposed in the area between the cabinet and the drum assembly 24, specifically in the area between the cabinet and the outer drum. The hydrogen peroxide generator 10 is disposed outside the dispensing component 23 and connected to the dispensing component 23.

[0137] Of course, it is also feasible to install the hydrogen peroxide generator 10 in other locations within the laundry equipment. For example, the hydrogen peroxide generator 10 can be placed in any suitable installation area between the cabinet and the outer drum, such as by directly fixing the hydrogen peroxide generator 10 to the cabinet, or by placing the hydrogen peroxide generator 10 side by side with the dispensing component 23, etc.

[0138] In some embodiments, refer to Figure 20 , Figure 21 and Figure 22 As shown, the hydrogen peroxide generator 10 includes a housing and an inlet 17 and an outlet 18 disposed on the housing. The housing 11 is provided with a cathode plate and an anode plate for electrolyzing water to generate hydrogen peroxide solution. The inlet 17 of the hydrogen peroxide generator 10 is connected to the water inlet channel 22, and the outlet 18 of the hydrogen peroxide generator 10 is connected to the dispensing component 23.

[0139] With this configuration, water is supplied to the hydrogen peroxide generator 10 through the water inlet channel 22. The hydrogen peroxide solution generated by the electrolysis of water in the hydrogen peroxide generator 10 is introduced into the dispensing component 23, and then enters the inner cavity of the clothes processing chamber 21 through the dispensing component 23. This realizes the use of the flow channel of the dispensing component 23 to transport the hydrogen peroxide solution into the inner cavity of the clothes processing chamber 21. With this configuration, there is no need to set an additional inlet for the hydrogen peroxide solution to enter the clothes processing chamber 21, which requires little modification to the original clothes washing equipment, is easy to process and manufacture, and has low cost.

[0140] Of course, if manufacturing costs and other factors are not considered, it is also feasible to additionally provide an inlet for introducing hydrogen peroxide solution on the garment processing chamber 21, directly connect the inlet 17 of the hydrogen peroxide generator 10 to the water supply line, and connect the outlet 18 of the hydrogen peroxide generator 10 to this inlet through a connecting pipe. In other words, the hydrogen peroxide solution generated by the hydrogen peroxide generator 10 is not limited to entering the garment processing chamber 21 through the dispensing component 23, but can also directly enter the garment processing chamber 21 through the connecting pipe.

[0141] It should be noted that the number of cathode and anode plates disposed within the housing 11 is not limited to one. For example, in... Figures 1 to 5In the illustrated embodiment, a cathode plate 12 and an anode plate 13 are disposed within the housing 11 of the hydrogen peroxide generator 10; in such a way... Figures 13 to 19 In the embodiment shown, the housing 11 of the hydrogen peroxide generator 10 is provided with two cathode plates and one anode plate 13, and the two cathode plates are the first cathode plate 121 and the second cathode plate 122, respectively.

[0142] In some embodiments, refer to Figure 20 and Figure 21 As shown, the dispensing component 23 includes a dispensing housing 230, a first water inlet channel 232, a second water inlet channel, and a water outlet channel 231. The first water inlet channel 232, the second water inlet channel, and the water outlet channel 231 are all connected to the inner cavity of the dispensing housing 230. The dispensing housing 230 is provided with a detergent dispensing port, and the water outlet channel 231 is connected to the clothing processing chamber 21. This configuration allows detergent to be dispensed into the inner cavity of the dispensing housing 230 of the dispensing component 23 through the detergent dispensing port. The detergent entering the inner cavity of the dispensing housing 230 is then transported to the clothing processing chamber 21 via the water outlet channel 231.

[0143] In some embodiments, refer to Figures 20 to 22 As shown, the outlet of the first water inlet branch 221 is connected to the first water inlet channel 232, the outlet of the second water inlet branch 222 is connected to the liquid inlet 17 of the hydrogen peroxide generator 10, and the liquid outlet 18 of the hydrogen peroxide generator 10 is connected to the second water inlet channel. This arrangement allows water to be supplied to the inner cavity of the dispensing housing 230 of the dispensing component 23 via the first water inlet branch 221, thereby flushing the detergent dispensed in the dispensing housing 230 and ensuring that the detergent enters the inner cavity of the clothing processing chamber 21 via the water outlet channel 231, achieving the purpose of delivering detergent into the inner cavity of the clothing processing chamber 21. It also allows water to be supplied to the hydrogen peroxide generator 10 via the second water inlet branch 222, thereby enabling the hydrogen peroxide generator 10 to electrolyze water to generate hydrogen peroxide solution, which enters the inner cavity of the clothing processing chamber 21 via the water outlet channel 231, achieving the purpose of delivering hydrogen peroxide solution into the inner cavity of the clothing processing chamber 21.

[0144] It should be noted that the water inlet path 22 is not limited to including two water inlet branches. It can also be set with three or more water inlet branches as needed, and the hydrogen peroxide generator 10 is set on one of the water inlet branches.

[0145] For example, refer to Figure 20 and Figure 21As shown, the water inlet path 22 includes three water inlet branches: a first water inlet branch 221, a second water inlet branch 222, and a third water inlet branch 223. The dispensing component 23 includes three water inlet channels: a first water inlet channel 232, a second water inlet channel 222, and a third water inlet channel 233. The outlets of the first water inlet branch 221 and the third water inlet branch 223 are directly connected to the dispensing component 23. Specifically, the outlet of the first water inlet branch 221 is connected to the first water inlet channel 232, and the outlet of the second water inlet branch 222 is connected to the third water inlet channel 223. The outlet of the second water inlet branch 222 is connected to the third water inlet channel 233. The hydrogen peroxide generator 10 is connected between the second water inlet branch 222 and the dispensing component 23. Specifically, the outlet of the second water inlet branch 222 is connected to the liquid inlet 17 of the hydrogen peroxide generator 10, and the liquid outlet 18 of the hydrogen peroxide generator 10 is connected to the second water inlet channel on the dispensing component 23. The hydrogen peroxide solution generated by the electrolysis of water by the hydrogen peroxide generator 10 can be transported to the inner cavity of the clothing treatment chamber 21 through the dispensing component 23.

[0146] It should be understood that the dispensing component 23 is generally provided with at least two dispensing ports for dispensing laundry detergent, fabric softener, etc., respectively. Through the above configuration, the laundry detergent is flushed into the inner cavity of the garment processing chamber 21 by the first water inlet branch 221, the fabric softener is flushed into the inner cavity of the garment processing chamber 21 by the third water inlet branch 223, and the hydrogen peroxide solution is flushed into the inner cavity of the garment processing chamber 21 by the second water inlet branch 222, thereby meeting different washing needs.

[0147] In some embodiments, refer to Figure 21 and Figure 22 As shown, the dispensing casing 230 includes a casing body and a pull-out box that can be pulled out and disposed inside the casing body. The pull-out box is provided with a detergent dispensing port. The casing body is provided with a water outlet channel 231 that communicates with the detergent dispensing port and / or the clothing processing chamber 21. The hydrogen peroxide generator 10 is installed at the rear end of the casing body along the pulling direction.

[0148] Specifically, the outer casing of the dispensing component 23 is typically fixed to the cabinet or drum assembly 24 of the laundry equipment (e.g., a drum washing machine). The outer casing of the dispensing component 23 is a box-shaped structure with an open front end. The pull-out box can be inserted into the outer casing through the front opening and pulled out in the opposite direction of insertion to dispense detergent into the detergent dispensing port. A handle is typically provided at the front end of the pull-out box along the pulling direction for pulling out the box. The hydrogen peroxide generator 10 is installed at the rear end of the outer casing along the pulling direction, for example, by using screws to fix the hydrogen peroxide generator 10 to the outer casing. By making minor structural modifications to the outer casing of the dispensing component 23, the hydrogen peroxide generator 10 can be installed on the dispensing component 23 and can be hidden inside the laundry equipment without affecting its aesthetics.

[0149] In some embodiments, the housing 11 of the hydrogen peroxide generator 10 is provided with a first connecting portion, and the outer shell of the dispensing component 23 is provided with a second connecting portion corresponding to the first connecting portion. The hydrogen peroxide generator 10 is fixed to the outer shell by fasteners passing through the first connecting portion and the second connecting portion. Specifically, the first connecting portion can be the third mounting portion 1116 described in the above embodiments, and the third mounting portion 1116 can specifically be a screw post.

[0150] In practical implementation, to ensure the secure fixation of the hydrogen peroxide generator 10 to the dispensing component 23, screw posts can be provided on both the first and second housing parts of the hydrogen peroxide generator 10, so that both the first and second housing parts are fixed to the dispensing component 23 by screws. Of course, the method of fixing the hydrogen peroxide generator 10 to the dispensing component 23 is not limited to screw fixing; snap-fit, adhesive, or other methods can also be used to fix the hydrogen peroxide generator 10 to the dispensing component 23.

[0151] In other embodiments, the hydrogen peroxide generator 10 is disposed within the garment processing chamber 21, which is used to hold washing water. The inlet 17 of the hydrogen peroxide generator 10 is at least partially submerged in the washing water. That is, the washing water can enter the housing 11 through the inlet 17 and be electrolyzed by the cathode plate 12 and the anode plate 13 to generate a hydrogen peroxide solution.

[0152] Taking a drum washing machine as an example, the laundry equipment includes a drum assembly 24, which specifically includes an outer drum and an inner drum disposed within the outer drum. A washing water circulation chamber is formed between the inner and outer drums, meaning that the washing water can circulate between the inner and outer drums. The hydrogen peroxide generator 10 can be disposed between the inner and outer drums, and the inlet 17 is at least partially immersed in the washing water. This means that the washing water can enter the interior of the housing 11 through the inlet 17 and undergo electrolysis through the cathode plate 12 and anode plate 13 to generate a hydrogen peroxide solution. It is understood that the hydrogen peroxide generator 10 can utilize the washing water in the inner drum for electrolysis and transport the generated hydrogen peroxide solution between the inner and outer drums. The hydrogen peroxide solution can enter the inner drum along with the washing water to clean and disinfect the clothes. It should be noted that the hydrogen peroxide generator 10 can also be disposed in other locations within the laundry equipment 20, as long as it can directly utilize the washing water in the inner drum and electrolyze it to generate hydrogen peroxide. This disclosure does not impose any limitations on this.

[0153] Other embodiments of this disclosure provide a garment processing device 30, including a garment container 31, a water addition line 32, and a hydrogen peroxide generator 10. The hydrogen peroxide generator 10 is disposed on the water addition line 32 and is used to electrolyze water to generate a hydrogen peroxide solution. The garment processing device also includes an atomizer 33 and / or a steam generator. The steam generator and / or atomizer 33 is connected between the water addition line 32 and the garment container 31 and is used to convert the hydrogen peroxide solution into hydrogen peroxide vapor and / or water mist to provide hydrogen peroxide vapor and / or water mist to the garment container 31.

[0154] Specifically, the clothing processing equipment 30 can be a dryer, as shown in the reference. Figure 8 As shown; the garment processing device 30 can also be a care cabinet, see reference. Figure 9 As shown; of course, the garment processing device 30 can also be other devices, and this disclosure does not limit it.

[0155] Understandably, both the dryer and the care cabinet can generate high-temperature water mist through a steam generator and / or atomizer 33. This high-temperature water mist, moving randomly within the garment container 31, can remove residual moisture from the clothes, achieving drying and softening effects. The water required by the steam generator and / or atomizer 33 is supplied through a water supply pipe 32. A hydrogen peroxide generator 10 is installed on the water supply pipe 32. The electrolyzed hydrogen peroxide solution can enter the steam generator and / or atomizer 33 through the water supply pipe 32, where it is converted into water mist and hydrogen peroxide vapor. This water mist and hydrogen peroxide vapor then enter the garment container 31 to dry, deodorize, sterilize, and soften the clothes. Specifically, the atomizer 33 can be an ultrasonic atomizer or a heated atomizer. Since hydrogen peroxide decomposes at 90°C, it can be atomized using either ultrasonic or heated methods. The atomized hydrogen peroxide can diffuse into the gaps between the dryer (or care cabinet) and the fabric for sterilization and deodorization.

[0156] Specifically, the garment processing device 30 includes a housing 34, a garment container 31 housed within the housing 34, a water tank for adding water on the housing 34, and a hydrogen peroxide generator 10 located at the water tank, using the water in the water tank to supply the hydrogen peroxide generator 10 with the water required for electrolysis. In a specific implementation, the hydrogen peroxide generator 10 includes a housing 11 and an inlet 17 and an outlet 18 located on the housing 11. The housing 11 contains a cathode 12 and an anode 13 for electrolyzing water to generate a hydrogen peroxide solution. The inlet 17 is connected to the water tank, and the outlet 18 is connected to the inlet of the water addition pipeline 32. This configuration eliminates the need for an additional water system, allowing the preparation and delivery of hydrogen peroxide directly using the water tank and water addition pipeline 32 already present in the garment processing device 30. This enables simultaneous drying, deodorization, sterilization, and softening of garments, thus improving the performance of the garment processing device 30.

[0157] Other embodiments of this disclosure provide an air conditioner 40, see reference to Figure 10 As shown, the device includes a housing 41, a condensate collection device, and a hydrogen peroxide generator 10. The condensate collection device is installed inside the housing 41 and is used to collect the condensate generated by the air conditioner 40 during operation. The hydrogen peroxide generator 10 is connected to the condensate collection device and is used to electrolyze the condensate to generate a hydrogen peroxide solution. An air outlet is provided on the housing 41 so that the hydrogen peroxide solution can be blown out through the air outlet.

[0158] Understandably, when the air conditioner 40 is working, a lot of condensate will be generated in the condensate collection device connection. The condensate needs to be discharged outward along the relevant pipes. The condensate collection device of the air conditioner 40 is connected to the hydrogen peroxide generator 10. The hydrogen peroxide generator 10 can directly use the condensate for electrolysis. The hydrogen peroxide solution generated by electrolysis is connected to the air outlet of the air conditioner 40 and blown into the room under the action of wind, so as to use hydrogen peroxide to remove odors in the indoor air and achieve the effect of freshening the air.

[0159] In a specific implementation, the hydrogen peroxide generator 10 includes a housing 11 and an inlet 17 and an outlet 18 disposed on the housing 11. The housing 11 contains a cathode 12 and an anode 13 for electrolyzing water to generate hydrogen peroxide solution. The inlet 17 is connected to a condensate collection device via a first pipe, and the outlet 18 leads to an air outlet via a second pipe. Both the first and second pipes are located inside the air conditioner 40. The first pipe connects the condensate collection device and the inlet 17, transferring condensate to the hydrogen peroxide generator 10. The second pipe connects the outlet 18 to the air outlet of the air conditioner 40, delivering the hydrogen peroxide solution to the air outlet, where it is blown into the room by the wind. This air conditioner 40 can directly recycle the condensate generated during operation, improving its air purification capabilities.

[0160] Other embodiments of this disclosure provide a dehumidifier (not shown) including a body and a water container, a steam generator, and a hydrogen peroxide generator 10 disposed on the body. The hydrogen peroxide generator 10 is connected between the water container and the steam generator and is used to electrolyze the water in the water container to generate a hydrogen peroxide solution. The steam generator is used to atomize the hydrogen peroxide solution to generate hydrogen peroxide vapor. The body is provided with a steam outlet so that the hydrogen peroxide vapor is blown out through the steam outlet.

[0161] Understandably, a dehumidifier generates high-temperature steam via a steam generator. The water required by the steam generator is provided through a water container. A hydrogen peroxide generator 10 is connected between the water container and the steam generator; that is, the water container is connected to the inlet 17 of the hydrogen peroxide generator 10, and the outlet 18 of the hydrogen peroxide generator 10 is connected to the steam generator. With this configuration, the hydrogen peroxide generator 10 can directly utilize the water in the water container for electrolysis to produce a hydrogen peroxide solution. This solution enters the steam generator and is atomized to form water vapor and hydrogen peroxide vapor. The water vapor and hydrogen peroxide vapor then flow to the steam outlet and are blown into the room, thus improving indoor air quality.

[0162] Other embodiments of this disclosure provide a refrigerator 50, see reference to Figure 11As shown, the device includes a refrigerator compartment 51, a hydrogen peroxide generator 10, and an atomizer 33. The hydrogen peroxide generator 10 is used to electrolyze water to produce a hydrogen peroxide solution. The hydrogen peroxide generator 10 has an inlet 17 for adding water and an outlet 18 for discharging the hydrogen peroxide solution produced by electrolyzing water. The atomizer 33 is connected between the outlet 18 and the refrigerator compartment 51. The atomizer 33 is used to atomize the hydrogen peroxide solution to produce hydrogen peroxide vapor, so as to provide hydrogen peroxide vapor to the refrigerator compartment 51.

[0163] In practice, water required for electrolysis is manually added to the inlet 17 of the refrigerator 50. The hydrogen peroxide solution produced by the electrolysis of water is discharged through the outlet 18 and enters the atomizer 33. The atomizer 33 generates hydrogen peroxide vapor, which can enter the refrigerator compartment 51. Hydrogen peroxide has the ability to sterilize and disinfect, and can remove bacteria and other microorganisms in the refrigerator compartment 51, thereby improving the sterilization and preservation capabilities of the refrigerator 50. Of course, it should be noted that the hydrogen peroxide generator 10 can also be connected to the freezer compartment of the refrigerator 50, and the hydrogen peroxide vapor can enter the freezer compartment to disinfect and sterilize it. This disclosure does not limit this.

[0164] Other embodiments of this disclosure provide a dishwasher 60, see reference to Figure 12 As shown, the device includes a washing chamber, a water inlet channel 22, and a hydrogen peroxide generator 10. The water inlet channel 22 is connected to the washing chamber and can supply washing water to the washing chamber. The hydrogen peroxide generator 10 is installed on the water inlet channel 22 or inside the washing chamber. The hydrogen peroxide generator 10 is used to electrolyze water to generate a hydrogen peroxide solution, which is then supplied to the washing chamber.

[0165] In some embodiments, the hydrogen peroxide generator 10 is installed on the water inlet channel 22. The hydrogen peroxide generator 10 can directly use the water in the water inlet channel 22 to perform electrolysis, and the hydrogen peroxide solution generated by electrolysis is transported to the dishwashing cavity through the water inlet channel 22. This can improve the cleaning ability of the dishwasher 60 without having to add detergent multiple times. When the hydrogen peroxide generator 10 is installed in the dishwashing cavity, it can directly use the washing water in the dishwashing cavity to perform electrolysis and generate hydrogen peroxide solution to wash pots and pans.

[0166] Specifically, the hydrogen peroxide generator 10 includes a housing 11 and an inlet 17 and an outlet 18 disposed on the housing 11. The housing 11 is provided with a cathode plate 12 and an anode plate 13 for electrolyzing water to generate hydrogen peroxide solution. When the hydrogen peroxide generator 10 is disposed on the water inlet channel 22, the inlet 17 is connected to the inlet of the water inlet channel 22, and the outlet 18 is connected to the outlet of the water inlet channel 22. The cleaning ability of the dishwasher 60 can be improved without the need to add detergent multiple times.

[0167] In other embodiments, the hydrogen peroxide generator 10 is disposed in the dishwashing chamber, and the inlet 17 is at least partially immersed in the washing water in the dishwashing chamber. It is understood that the hydrogen peroxide generator 10 can utilize the washing water in the dishwashing chamber for electrolysis and deliver the generated hydrogen peroxide solution to the dishwashing chamber for washing pots, pans, etc.

[0168] It should be noted that the hydrogen peroxide generator 10 is not limited to use in laundry equipment 20, laundry treatment equipment 30, air conditioner 40, dehumidifier, refrigerator 50, and dishwasher 60. It can also be applied to other household appliances as needed.
