Description

Technical Field

[0001] This invention relates to the field of ozone-generating equipment for water electrolysis, specifically to a household appliance-based ozone-generating equipment for water electrolysis. Background Technology

[0002] Household water electrolysis ozone generators (such as those used for fruit and vegetable disinfection and tableware cleaning) typically require an ion exchange resin filter before the electrolysis unit to remove scale-forming ions like calcium and magnesium from the water in order to achieve efficient and stable ozone production. However, this filter is a disposable component and must be replaced by the user once it becomes saturated.

[0003] Existing technical solutions suffer from the following significant drawbacks: First, poor economic efficiency: dedicated replacement filter cartridges are expensive due to their integrated packaging, becoming a continuous cost burden for users. Second, low convenience: replacement requires interrupting equipment use, and because household appliances have limited internal space, filter modules are typically installed in small locations with high structural integration, making disassembly and replacement cumbersome. This presents a high technical barrier and poor user experience for ordinary users, and can easily damage surrounding components. These drawbacks directly lead to low user willingness to proactively maintain the equipment, resulting in many devices operating for extended periods in a resin-ineffective state, causing irreversible degradation of electrolysis efficiency and a significant shortening of equipment lifespan.

[0004] Therefore, there is an urgent need in this field for an improved solution suitable for home use, in order to fundamentally solve the problems of high maintenance costs and low convenience caused by disposable filter cartridges under limited cost and space constraints. Summary of the Invention

[0005] The purpose of this invention is to provide a household appliance-based ozone generator for electrolyzing water, which facilitates the improvement of water deionization efficiency and utilization efficiency, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ozone-generating device for water electrolysis in household appliances, comprising a water storage tank and an ozone generating module. The ozone generating module includes an electrolysis unit, a deionization unit, a switching drive unit, and a regeneration and cleaning unit. The electrolysis unit is used to electrolyze water to generate ozone-containing gas. The deionization unit is located upstream of the electrolysis unit and is used to deionize the water entering the electrolysis unit. The deionization unit has at least two independently operable deionization components. The switching drive unit can respond after the ozone concentration output by the ozone generating module has been continuously lower than a set threshold for a set time, driving one of the at least two deionization components to exit the working position and enter the regeneration position, while simultaneously driving the other deionization component that has completed regeneration to enter the working position, so as to realize continuous deionization treatment. The regeneration and cleaning unit is used to perform regeneration and cleaning operations on the deionization component in the regeneration position, which facilitates the improvement of water deionization efficiency and utilization efficiency.

An exhaust pipe is connected to the connecting pipe, and the exhaust pipe passes through the tank cover. The exhaust pipe is used to output the gas generated by electrolysis, and a detection element for detecting the ozone output concentration is provided in the exhaust pipe. This facilitates the deionization operation by exchanging anions and cations in the water body through the deionization component, and controls the rotating cylinder to rotate and switch when the output ozone concentration is lower than a set value. The deionization component is self-cleaned by the regeneration and cleaning unit, and the cleaned deionization component is switched to the working state to continue the deionization operation.

The side of the fixed cylinder away from the connecting pipe is connected to a first drain pipe and a second drain pipe. The first water supply pipe and the first drain pipe can be connected to both ends of the storage cylinder at the same time. The second water supply pipe and the second drain pipe can be connected to both ends of the storage cylinder at the same time. The water tank is provided with a conveying component for storing and conveying fluid, which facilitates self-cleaning of the deionization component during the rotation and switching of the rotating cylinder.

[0010] Preferably, the conveying component includes a first solution box and a second solution box fixedly installed inside the water storage tank. The top end of the first pipe is connected to the first solution box, and the top end of the second pipe is connected to the second solution box.

A bend is fixedly connected inside the collection box. The height of both ends of the bend is lower than the height of the middle position, and the height of the middle position of the bend is lower than the height of the outlet positions of the first drain pipe and the second drain pipe, so as to facilitate the neutralization and output of sewage.

[0012] Preferably, the electrolysis unit includes two sets of copper terminals fixedly installed inside the housing. A proton exchange membrane is fixedly connected to the copper terminals. Electrode plates are fixedly connected to both the upper and lower sides of the proton exchange membrane. A power supply plate is fixedly connected to the sides of each of the two sets of electrode plates. The copper terminals on both sides are electrically connected to different electrode plates. Multiple sets of interconnected slots are formed on the electrode plates to facilitate the electrolysis of water to generate ozone.

[0013] Preferably, the electrolysis unit further includes wires fixedly connected to the two sets of copper terminals. The wires pass through the box cover. A glue-applying groove is provided on the box body. The box cover is inserted into the glue-applying groove. Resin glue is fixedly connected inside the box cover. The wires pass through the resin glue and are fixedly connected to the resin glue to ensure the sealing of the box body.

[0014] Preferably, the switching drive unit includes a drive motor fixedly installed on the side wall of the water storage tank.

The end of the drive shaft away from the drive motor is coaxially fixedly connected to the side of the rotating cylinder, which facilitates driving the rotating cylinder to rotate and switch.

[0015] A method for continuously producing ozone using a household appliance-based water electrolysis ozone generator includes the following steps: S1: The water is sequentially deionized by passing through the deionization component in the working position, and then enters the electrolysis unit to be electrolyzed to generate ozone. S2: Real-time monitoring and output of ozone concentration; S3: When the ozone concentration remains below the set threshold for a set period of time, control the switching drive unit to switch the current deionization component to the regeneration station and switch the deionization component that has completed regeneration to the working station. S4: At the regeneration station, the deionization unit is sequentially subjected to acid regeneration, rinsing, alkali regeneration, and rinsing operations; S5: Repeat steps S1-S4 to achieve uninterrupted ozone production.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a water electrolysis ozone generator for household appliances, solving the problems of inconvenience and inefficiency in the use and maintenance of existing water electrolysis ozone generators for household appliances. It generates ozone by electrolyzing water through an electrolysis unit, and deionizes the anions and cations in the water through a deionization component. When the output ozone concentration continuously falls below a set threshold, a switching drive unit controls the switching of the deionization component. A regeneration and cleaning unit performs self-cleaning of the deionization component, and simultaneously switches the cleaned deionization component back to working state to continue deionization. This makes operation more convenient and efficient, eliminating the need for power outages and shutdowns. Electrolysis can continue during the switching process while the deionization component self-cleanses, significantly improving efficiency. Attached Figure Description

[0024] Please see Figures 1-12 This invention provides a method for continuous ozone production using a household appliance-based water electrolysis ozone generator, comprising the following steps: S1: The water is sequentially deionized by passing through the deionization component 7 in the working position, and then enters the electrolysis unit to be electrolyzed to produce ozone. S2: Real-time monitoring and output of ozone concentration; S3: When the ozone concentration remains below the set threshold for a set time, control the switching drive unit 15 to switch the current deionization component 7 to the regeneration station and switch the deionization component 7 that has completed regeneration to the working station. S4: At the regeneration station, acid regeneration, rinsing, alkali regeneration, and rinsing are performed sequentially on the deionization unit 7. S5: Repeat steps S1-S4 to achieve uninterrupted ozone production.

[0025] Working principle: Water is filled into the water tank 1. When the water enters the box 2, it first passes through the inlet pipe 12, storage cylinder 9, connecting pipe 13, and delivery pipe 3 before reaching the area around the electrode plate 31 inside the box 2. By connecting the electrode plate 31 with the wire 34 and energizing it, the electrode plate 31 can complete the electrolysis of the water. The connecting groove 33 provides a channel for the proton exchange membrane 30 to enter the water, providing more active sites. The water entering the box 2 undergoes ion exchange with the ion exchange resin 11 inside the storage cylinder 9 to obtain deionized water, which is then transported to the connecting pipe 13. This ensures that the water around the electrode plate 31 is in a deionized state, effectively improving the electrolysis efficiency and extending the service life of the electrode plate 31. The ozone and other gases generated by electrolysis will overflow through the exhaust pipe 14 above the connecting pipe 13, realizing the ozone output function. At the same time, the filter screens 10 at both ends of the storage cylinder 9 can block larger particles in the water, preventing them from entering the box 2.

[0026] When the detector shows that the output ozone concentration is lower than the set value (the ozone sensor triggers the subsequent switching operation if the ozone concentration is lower than 70% for 5 minutes), it indicates that the ion exchange resin 11 has a low ion exchange efficiency and needs regeneration. The drive motor 38 is started, driving the drive shaft 39 to rotate the rotating cylinder 5 72° (the attached diagram in the manual shows a switching design with five sets of storage cylinders 9). This completes one switching of the storage cylinder 9 positions, causing the storage cylinder 9 connected to the connecting pipe 13 to rotate to the side position, while the other set of cleaned storage cylinders 9 rotates to the position connected to the connecting pipe 13 for subsequent ion exchange treatment. At this point, no shutdown is required, and the equipment can continue electrolysis. The system improves efficiency and reduces maintenance frequency. The storage cylinder 9, rotated to the side, connects to the first pipe 16. The first pipe 16 feeds 5% hydrochloric acid solution or 8% sodium chloride solution from the first solution box 23 into the storage cylinder 9. The amount fed is calculated based on the volume of the storage cylinder 9. A control valve inside the first pipe 16 controls the supply. After dilution of the original liquid inside the storage cylinder 9, approximately 3% hydrochloric acid solution or 4% sodium chloride solution is obtained. This solution is used to soak the ion exchange resin 11 for at least one hour (or can be continuously soaked). During the soaking process, the hydrochloric acid or sodium chloride solution reacts with alkaline ions, continuously reducing the acidity of the solution, ultimately leading to a more stable solution. The liquid inside cylinder 9 is extremely weakly acidic, so prolonged immersion in the ion exchange resin will not affect it. This reduces the amount of alkaline ions adsorbed inside. Then, the position of cylinder 9 is switched again (the switching time is determined by the ion exchange resin 11 at the bottom; a switching operation is performed when the bottom ion exchange resin 11 needs regeneration). This connects both ends of cylinder 9 to the first water supply pipe 18 and the first drain pipe 20, respectively. The peristaltic pump 25 draws deionized water from the connecting pipe 13 into the first and second water supply pipes 18 and 19, allowing for a slow-flow rinsing of cylinder 9. This reduces the acid concentration inside and also removes impurities blocked by the filter screen 10. The ion exchange resin 11 is cleaned and then discharged into the collection box 27 for storage. A pH meter is installed in the first drain pipe 20 and the second drain pipe 21 to detect the pH of the discharged liquid. When the pH of the discharged liquid is close to 7, the peristaltic pump 25 is turned off. This indicates that the ion exchange resin 11 is in a relatively neutral state and will not introduce acid or alkali residues into the proton exchange membrane 30 to poison it during subsequent use. When backwashing the ion exchange resin after regeneration, it is recommended to control the flow rate of deionized water delivered by the peristaltic pump 25 at 5-15 m / h (the linear velocity of the resin bed cross-section). The volumetric flow rate needs to be calculated in conjunction with the cross-sectional area of ​​the ion exchange resin 11 (volumetric flow rate = linear velocity × cross-sectional area).

[0027] Then, the position of the storage cylinder 9 is switched again, with one end of the storage cylinder 9 connected to the second pipe 17. The second pipe 17 feeds an 8% sodium hydroxide solution or an 8% sodium bicarbonate solution from the second solution box 24 into the storage cylinder 9 to soak the ion exchange resin 11. The amount of solution fed in is calculated based on the volume of the storage cylinder 9. A control valve inside the second pipe 17 controls the supply of liquid. After dilution of the original liquid inside the storage cylinder 9, approximately a 4% sodium hydroxide solution or a 4% sodium bicarbonate solution is obtained. The required soaking time (more than 1 hour, or continuous soaking is also possible, as the sodium hydroxide or sodium bicarbonate solution reacts with acidic ions during soaking, continuously reducing the alkalinity of the solution until the liquid inside the storage cylinder 9 is extremely weakly alkaline, and prolonged soaking of the ion exchange resin 11 will not have any effect) is used to reduce the adsorbed acidic ions. Then, the position of the storage cylinder 9 is switched again, so that both ends of the storage cylinder 9 are connected to the second water supply pipe 19 and the second drain pipe 21, respectively. After rinsing for the set time, the ion exchange resin 11 can be restored. The ion adsorption capacity of the regenerated ion exchange resin 11 is enhanced. The acidic solution and alkaline solution generated during the rinsing process are transported to the collection tank 27 through the first drain pipe 20 and the second drain pipe 21, respectively, for mixing and neutralization. The resulting mixed solution is collected in the collection tank 27 and, after the liquid level reaches the middle of the bend pipe 28, is drawn out into the sewage pipe. The bend pipe 28 is designed to prevent the acid or alkaline wastewater from being discharged directly without neutralization, and to prioritize the discharge of the completely reacted liquid at the bottom. The accumulated water inside the collection tank 27 is gradually discharged using a siphon effect, without the need for manual control of its opening and closing. Afterward, the position of the storage cylinder 9 is switched again to switch the regenerated ion exchange resin 11 to the bottom and connect it to the connecting pipe 13. The device is equipped with five groups of ion exchange resins 11, which can be in different states during the switching process, ensuring that the regeneration and adsorption operations are carried out simultaneously. No machine shutdown is required during the switching process, and ozone can be continuously generated, improving the efficiency of use and greatly reducing manual maintenance time, making it more convenient and efficient to use.

[0028] It is worth noting that the electrolysis state can be directly controlled via wire 34. The two sets of electrode plates 31 are the anode plate and the cathode plate, respectively. The proton exchange membrane 30 adopts a zero-gap bonding design with the anode and cathode plates on both sides. Through a specific pressing process and structure, the water gap or air gap between the traditional membrane electrodes is eliminated, forming a tight "sandwich" structure. This structure greatly reduces ohmic loss and improves reaction efficiency and current density, which is the key to achieving high-concentration ozone production. The entire electrolysis module is wrapped with an insulating sleeve, which is preferably made of materials with excellent insulation, corrosion resistance and mechanical properties such as EVA. At the periphery of each reaction unit and at the flow channel interface, a special sealing plate is used for sealing. This sealing plate is preferably made of ozone-resistant, aging-resistant and highly elastic sealing materials such as 6105 sealing silicone plate. The entire stacked structure is pressed together by applying uniform preload through the end plate and multiple long bolts, ensuring that the layers maintain excellent stability under high pressure. The electrolysis unit is designed with standardized dimensions, such as a total length of 78.2 mm and a width of 33.7 mm. It integrates water inlet, water outlet, exhaust, and electrode interfaces. This compact, integrated design facilitates installation and integration into various terminal products. The water tank 1 can be connected to a household water inlet pipe and output ozone through the exhaust pipe 14 to disinfect household appliances such as washing machines and dishwashers. Corrosion-resistant sealing structures are set on both sides of the rotating drum 5 and the opening of the storage cavity 6. During rotation, the two ends of the storage drum 9 are always sealed and connected to only one set of pipes, preventing internal fluid from leaking to the surroundings. This sealing structure can use a rotating lip seal ring, with corrosion-resistant elastic material (fluororubber FKM) as the main body, which is attached to the mating end face / circumferential surface of the rotating drum 5 and the opening of the storage cavity 6. It forms a sealing contact strip by relying on pre-compression force. Fluororubber is resistant to acids, alkalis, and organic solvents and is suitable for harsh working conditions.

[0029] The combination of hydrochloric acid and sodium hydroxide solution has a stronger acid-base relationship, requiring a higher level of overall equipment sealing and posing a relatively higher operational risk. It can be replaced with sodium chloride and sodium bicarbonate solutions. A 5%–10% sodium chloride solution can replace hydrochloric acid. The principle is... Adsorbed on the displacement resin , It is an isocation, the reaction is mild and non-corrosive, no additional protection is required during operation, and a 5%~8% sodium bicarbonate solution can be used instead of sodium hydroxide. Can replace resin , The solution is anionic and weakly alkaline, exhibiting extremely low corrosivity to skin and equipment, significantly enhancing safety. The drawback is that its regeneration efficiency is slightly lower than the combination of hydrochloric acid and sodium hydroxide, potentially requiring a longer soaking time. However, this solution avoids frequent switching of the ion exchange resin position; switching is typically done once every one to two days, with the specific frequency depending on usage. Therefore, after at least 24 hours of soaking, the reduction effect is already relatively good. Furthermore, the slow rinsing time with deionized water can be controlled based on the pH of the output wastewater, potentially extending to 24 hours, effectively preventing residual ions from poisoning the proton exchange membrane. The regeneration function in this solution is "maintenance regeneration," not industrial-grade complete regeneration, designed to assist in extending the ion exchange membrane's lifespan. The overall lifespan of ion exchange resin 11 improves its deionization efficiency during subsequent use to a certain extent. However, due to the limited size of the equipment and the simplification of its structure, its regeneration effect is inevitably far less significant than that of industrial-grade regeneration operations. In particular, the regeneration effect will be weakened when using a combination of sodium chloride and sodium bicarbonate. However, during use, it will inevitably adsorb excess anions and cations inside ion exchange resin 11, thereby improving the deionization efficiency of ion exchange resin 11 during subsequent use. Compared with household equipment without regeneration function, it can achieve better usage results, reduce the frequency of replacement operations, and extend the overall lifespan of the equipment.

[0030] Example 2: A multi-way parallel valve group can also be used to replace the structure of rotating cylinder 5 and storage chamber 6: Multiple independent deionization components 7 (storage cylinder 9 + ion exchange resin 11 + filter screen 10) are set in the water storage tank 1. Each deionization component 7 is connected to the inlet pipe 12, connecting pipe 13, first pipe 16, second pipe 17, first water supply pipe 18, second water supply pipe 19, first drain pipe 20 and second drain pipe 21 at both ends through electromagnetic reversing valves. When the ozone concentration remains below the set threshold for an extended period, the control system switches the electromagnetic reversing valve to disconnect the working circuit of the failed deionization component 7 and connect it to the regeneration circuit of the first pipe 16-first water supply pipe 18-first drain pipe 20-second pipe 17-second water supply pipe 19-second drain pipe 21. The electromagnetic reversing valve is then sequentially controlled to open the required pipes for a certain working time, gradually completing the regeneration operation of the deionization component 7. At the same time, the regenerated deionization component 7 is connected to the working circuit, realizing the online regeneration and continuous working function equivalent to the structure of the rotating cylinder 5. This result requires a larger number of electromagnetic reversing valves, and the connection state of the pipes is more complex than in Embodiment 1, but the overall principle is not much different from Embodiment 1, and will not be elaborated here.
