Description

Technical Field

[0001] This application belongs to the field of washing technology and relates to a dishwasher, specifically an electrolyzed water sterilization dishwasher that utilizes electrolyzed water to achieve efficient and convenient sterilization. Background Technology

[0002] With economic development and technological advancements, dishwashers have gradually become one of the core appliances in family kitchens. Dishwashers replace traditional hand washing, freeing up hands, improving cleaning efficiency, and saving time and water. However, the washing chamber inside a dishwasher, being in a humid environment for extended periods, is highly susceptible to bacterial growth. During the washing process, these bacteria can splash onto the dishes with the water, causing secondary contamination. Therefore, sterilization is an essential function of dishwashers. Currently, dishwashers generally rely on high-temperature water (70°C or higher) or chemical disinfectants such as ozone for sterilization. High-temperature water sterilization requires heating the water, resulting in higher energy consumption and is unsuitable for washing fruits and vegetables, as well as heat-sensitive tableware such as plastic and silicone. Ozone sterilization, on the other hand, poses potential safety hazards because excessive ozone concentrations can be harmful to humans.

[0003] The anode products generated during water electrolysis have high oxidation-reduction potentials and are promising for disinfection and sterilization. However, existing electrolysis devices often have the following two problems: (1) When the output is mixed, that is, when the cathode products and anode products are mixed together, the oxidation-reduction potential of the actual output electrolysis products often fails to meet expectations as the cathode products consume the anode products, and the sterilization and disinfection effects cannot meet the requirements; (2) When the output is split, that is, when the cathode products and anode products are output separately, the oxidation-reduction potential of the output anode products is guaranteed to avoid the consumption of the anode products by the cathode products; however, the cathode products are waste products, which will lead to serious water waste for dishwashers with large water consumption. Admittedly, the electrolysis of brine does not have the aforementioned two problems, but users need to constantly replenish the brine in the electrolysis chamber, which is complicated and reduces the user experience.

[0004] Therefore, how to achieve thorough disinfection while minimizing user steps is a technical problem that dishwashers urgently need to solve. Utility Model Content

[0005] To address the problems existing in the prior art, this application first provides an electrolyzed water sterilization dishwasher. The electrolyzed water sterilization dishwasher uses an electrolysis module independently developed by the inventor, which can achieve the sterilization requirements of the dishwasher with just regular water intake, eliminating the need for adding salt water and making full use of water resources. Furthermore, the electrolysis products output by the electrolysis module can also emulsify edible oils, reducing detergent usage to a certain extent and making it more environmentally friendly.

[0006] This application provides the following technical solution:

[0007] An electrolyzed water sterilization dishwasher includes an inlet pipe, a washing chamber and a drain pipe connected in sequence, and a circulation pipe connected to the washing chamber, one end of which is a spray arm disposed in the washing chamber.

[0008] It also includes an electrolysis module disposed at least once in the water inlet pipe, the washing chamber, and the circulation pipe. The electrolysis space of the electrolysis module is divided into a cathode chamber with a cathode and an anode chamber with an anode by a first partition. The water inlet and outlet of the electrolysis space are both disposed in the anode chamber. The first partition is an ion channel for cations.

[0009] In this application, by setting up an electrolysis module, the water flow used by the dishwasher is changed from ordinary tap water to water flow carrying electrolysis products and having bactericidal ability. This achieves disinfection treatment of the dishes while washing them, saving the time of additional sterilization process in the prior art.

[0010] In existing electrolysis modules, the anode and cathode chambers are separated by an ion exchange membrane when outputting cathode and anode products respectively. To prevent electrode dry-burning, inlets and outlets are provided at both chambers. However, due to the selectivity of ion exchange membranes, taking cation exchange membranes as an example, even if the raw water entering the cathode chamber participates in electrolysis at the cathode, the generated hydroxide ions cannot pass through the cation exchange membrane. Therefore, in this structure, some of the raw water entering the electrolysis space does not participate in electrolysis; it only dissolves the electrolysis products and prevents electrode dry-burning, resulting in a low conversion ratio between the electrolysis products and the actual influent volume.

[0011] The electrolysis module described in this application has its water inlet located only on one side of the anode chamber. Because the electrolysis module required for the electrolyzed water sterilization dishwasher is relatively small, the amount of water carried by ions during their migration from the anode chamber to the cathode chamber is sufficient to prevent the electrodes from drying out, thus overcoming the technical biases of the prior art.

[0012] Based on this, compared with the traditional diversion method, most of the raw water entering the electrolysis space in this application can participate in electrolysis at the anode chamber, resulting in a higher conversion ratio between the required electrolysis products and the actual influent volume. Furthermore, the separation effect of the first separator reduces the consumption of anode products by cathode products. Therefore, the water flow used to rinse tableware in this application carries a higher concentration of electrolysis products, achieving the disinfection effect expected by the user.

[0013] On the other hand, the inventors discovered that the water output from the electrolysis module of this application also has an emulsifying effect on edible oil and can participate in the process of washing tableware. In this regard, the inventors speculate that the reason why the electrolysis product has the function of emulsifying oil is because: (1) The electrolysis product of this application has strong oxidizing properties, and the main component of edible oil is triglycerides. The electrolysis product preferentially oxidizes unsaturated fatty acids such as oleic acid and linoleic acid, resulting in the breakage of ester bonds and the generation of hydrophilic products such as glycerol, fatty acid fragments and peroxides, which can be carried away with the water flow. (2) During the process of the ozone contained in the electrolysis product decomposing into oxygen, the formed microbubbles adhere to the surface of the oil, thereby achieving the effect of emulsifying oil.

[0014] Existing dishwashers typically include a heating module. This module heats the water to a set temperature, enabling it to disinfect the dishes. It also requires a relatively high water temperature to activate the detergent and ensure effective cleaning. However, the electrolyzed water sterilization dishwasher of this application, equipped with an electrolysis module, achieves washing and sterilization effects using room temperature water. This saves both the time and energy required for heating the water, resulting in significant advantages.

[0015] Furthermore, a water collection area is provided at the bottom of the washing chamber, and the water collection area is connected to the circulation pipeline through a first outlet;

[0016] The electrolysis module is located at least once in the water collection area or in the circulation pipeline connected to the water collection area.

[0017] Furthermore, the circulation pipeline includes a main pipeline, at least two spray arms, and several branch pipelines connected to the main pipeline, wherein the branch pipelines are connected to the spray arms.

[0018] The electrolysis module is located on the main road.

[0019] The electrolysis module installed on the water inlet pipe can no longer electrolyze the water after it enters the washing chamber. However, the electrolysis modules installed in the water collection area and circulation pipe can circulate and electrolyze the water, fully ensuring its ability to disinfect and emulsify grease.

[0020] However, for the electrolysis module located in the water collection area, it can only electrolyze the water flow around it. For water flow farther away, it is necessary to wait for the electrolysis products to diffuse over. Therefore, the electrolysis module is preferably located near the first outlet to ensure that the water flow entering the circulation pipeline carries a high concentration of electrolysis products. Alternatively, the electrolysis module can be directly installed on the main line of the circulation pipeline to ensure that the water flow sprayed onto the tableware by the spray arm carries a high concentration of electrolysis products and has the ability to disinfect and emulsify grease, thereby fully ensuring the cleaning and disinfection effect of the tableware.

[0021] Furthermore, the cathode chamber is provided with a hydrogen outlet, which connects the cathode chamber to the outside of the anode chamber.

[0022] The first separator is equipped with a gas check structure.

[0023] By setting up a gas check valve structure, hydrogen generated in the cathode chamber is prevented from diffusing into the anode chamber, reducing the consumption of anode products by cathode products and ensuring the required amount of electrolytic products output from the electrolysis module outlet. This, in turn, ensures the disinfection and cleaning capabilities of the water sprayed from the spray arm for the tableware.

[0024] Furthermore, a first gap is provided between the first separator and the peripheral wall of the electrolysis space, and the cathode chamber and the anode chamber are connected through the first gap;

[0025] The first separator is equipped with a water-blocking structure.

[0026] By incorporating a water-blocking structure and placing the water inlet of the electrolysis module solely on one side of the anode chamber, the amount of water entering the cathode chamber is reduced. Due to the limited water volume, less hydrogen dissolves in the water within the cathode chamber, and the probability of gaseous hydrogen reacting with the liquid anode products when diffusing into the anode chamber through the first gap is low. Therefore, although this structure outputs electrolysis products in a mixed-flow manner, it still reduces the unnecessary consumption of anode products, ensuring a sufficient amount of the required electrolysis products output, thereby guaranteeing the disinfection and cleaning capabilities of the water sprayed from the spray arm for the tableware.

[0027] Furthermore, the anode is disposed adjacent to the first separator, and the area of ​​the anode is smaller than the area of ​​the first separator;

[0028] A third gap is provided between the anode and the peripheral wall of the anode chamber, and / or a third gap is provided between the anode and the first partition;

[0029] The third gap is connected to the first gap.

[0030] Considering that the continuous accumulation of hydrogen in the cathode chamber may cause a significant impact on the first separator, causing it to expand towards the anode chamber, this application positions the anode and the first separator relatively close to each other to support the first separator and limit its expansion towards the anode chamber. Furthermore, it is necessary to ensure that the area of ​​the anode is smaller than the area of ​​the first separator so that hydrogen ions generated at the anode can pass through the first separator via the shortest path to the cathode to continue participating in electrolysis, reducing the electrolysis voltage required for ion migration. On the other hand, a third gap can also be provided between the anode and the first separator, and / or between the anode and the peripheral wall of the anode chamber, to achieve communication between the cathode chamber and the anode chamber, ensuring the smooth discharge of hydrogen generated at the cathode.

[0031] Furthermore, a second gap is provided between the cathode and the first partition, the area of ​​the cathode is smaller than the area of ​​the first partition, and / or a second gap is provided between the cathode and the peripheral wall of the cathode chamber;

[0032] The second gap is connected to the first gap.

[0033] The presence of a second gap between the cathode and the first separator indicates that the distance between them is close. Hydrogen ions generated at the anode enter the cathode chamber through the first separator and can directly participate in electrolysis at the cathode. Therefore, the electrolysis required to drive ion migration in this application requires a smaller voltage. On the other hand, when second gaps are provided between the cathode and the peripheral wall of the cathode chamber, and between the cathode and the first separator, the rate at which hydrogen diffuses into the anode chamber increases, reducing the impact on the first separator as its volume increases, and extending the service life of the first separator.

[0034] When the area of ​​the cathode is equal to the area of ​​the first separator, the water flowing into the cathode chamber cannot diffuse to the cathode chamber on the other side due to the obstruction of the cathode. In this case, only one side of the cathode participates in electrolysis, resulting in low utilization. Alternatively, when a second gap is provided between the cathode and the peripheral wall of the cathode chamber, although the cathode chambers on both sides of the cathode can be connected through the second gap, allowing water to participate in electrolysis at the cathode on the side away from the first separator, the diffusion rate of hydrogen to the cathode chamber on the other side is slow due to the size limitation of the second gap. Most of the hydrogen generated during electrolysis still accumulates between the first separator and the cathode, causing a significant impact on the first separator. In this application, the area of ​​the cathode is smaller than the area of ​​the first separator, allowing the water flowing into the cathode chamber to diffuse to the cathode chamber on the other side, improving the utilization rate of the cathode. At the same time, the increased space reduces the impact of hydrogen on the first separator, extending its service life.

[0035] Furthermore, the anode is at least part of the peripheral wall of the anode chamber, and the anode forms a semi-closed or closed enclosure around the electrolyzed raw water in the anode chamber;

[0036] The cathode chamber is fitted outside the anode chamber.

[0037] This application configures the peripheral wall of the anode chamber as the anode, which fully guarantees the electrolysis area when the volume of the electrolysis module is limited. On the other hand, under the inlet flow rate of daily water use, the water enters the electrolysis module in the form of turbulence. Under the action of the turbulent and irregular flow field, the water will continuously hit the anode surrounding it and participate in electrolysis. Therefore, the electrolysis efficiency of this application can also be guaranteed.

[0038] Furthermore, the anode chamber is provided with at least one water-blocking component to divide the initial water path between the inlet and the outlet into several interconnected second flow paths, wherein the width ratio of the second flow path to the initial water path is less than or equal to 0.5.

[0039] To improve electrode utilization, this application limits the width of the second flow path within the anode chamber using a water-blocking element. The water-blocking element guides the water flow, extending its path and ensuring sufficient coverage of the electrodes within the second flow path, thus improving electrode utilization. Consequently, the improved electrode utilization leads to higher output electrolysis product parameters, overcoming the technical deficiency of insufficient electrode utilization in existing technologies.

[0040] Furthermore, it also includes a humidity-sensitive element, which controls the control circuit of the electrolysis module to conduct when the electrolysis module is filled with water.

[0041] By setting a humidity-sensitive element, the control circuit of the electrolysis module is automatically turned on when water is flowing through the electrolysis module, and automatically turned off when water is not flowing through the electrolysis module. This not only avoids the electrolysis module from burning dry, but also ensures the starting efficiency of the electrolysis module, thereby ensuring the disinfection and cleaning ability of the water sprayed by the spray arm on the tableware.

[0042] After adopting the above technical solution, this application has the following beneficial effects:

[0043] 1. The electrolyzed water sterilization dishwasher described in this application uses an electrolysis module independently developed by the inventor, which can meet the user's expectations for the sterilization of tableware under normal water intake conditions; it avoids the cumbersome operation of constantly replenishing salt water when using an electrolyzed salt water device, solves the pain point of consumers, and has important practical application value.

[0044] 2. The water output from the electrolysis module described in this application, in addition to achieving basic disinfection, also has the function of emulsifying grease, and can clean and disinfect tableware at room temperature; compared with the high-temperature disinfection often used in the prior art, it saves energy.

[0045] 3. Compared with existing electrolysis devices, the electrolysis module described in this application improves the conversion ratio of electrolysis products to influent water, ensuring the concentration of electrolysis products carried by the washing water flow, thereby ensuring disinfection and cleaning capabilities. On the other hand, the electrolysis module is small in size and can be installed in multiple locations such as influent pipes, circulation pipes, and water collection areas, meeting diverse consumer needs and expanding the target audience.

[0059] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0061] For dishwashers, the washing chamber is a highly humid environment that easily breeds bacteria. During the washing process, these bacteria can splash onto the dishes with the water, contaminating them. Therefore, dishwashers have a high requirement for sterilization and disinfection.

[0062] When water is used as the electrolysis raw material, the anode product generated by electrolysis has a high redox potential, meaning it has strong oxidizing properties and can be used in sterilization applications. Furthermore, since the reaction product is water, it also offers the advantages of being environmentally friendly and residue-free. Therefore, it is particularly suitable for sterilization applications in dishwashers.

[0063] In view of this, such as Figure 1-9As shown, this utility model provides an electrolyzed water sterilization dishwasher. The electrolyzed water sterilization dishwasher includes a water inlet pipe 2, a washing chamber 1 and a drain pipe 5 connected in sequence. It also includes a circulation pipe 3 connected to the washing chamber 1. One end of the circulation pipe 3 is connected to the washing chamber 1, and the other end is a spray arm 301 installed in the washing chamber 1.

[0064] It should be noted that the water inlet pipe 2 can be directly connected to the washing chamber 1 to independently realize the water inlet function; or, as... Figure 1 and Figure 2 As shown, the water inlet pipe 2 realizes the water inlet function through the circulation pipe 3, and delivers water to the washing chamber 1. At this time, the water inlet pipe 2 is connected to the washing chamber 1 and the drain pipe 5 in sequence through the circulation pipe 3.

[0065] To achieve the sterilization requirement, this invention includes an electrolysis module 4 at least at one of the following: the water inlet pipe 2, the washing chamber 1, and the circulation pipe 3. The water flow output from the electrolysis module 4 carries electrolysis products and thus possesses sterilization capabilities. This water flow can disinfect the flow path, preventing bacteria from spreading to the tableware and contaminating it. Furthermore, it can directly disinfect the tableware during the washing process, saving the time required for additional sterilization steps such as ultraviolet sterilization and ozone sterilization in existing technologies.

[0066] In the existing technology, some manufacturers use high-temperature water of 70°C or higher to disinfect tableware. Although this method can also achieve sterilization while washing, it consumes a lot of energy because it requires heating the water. In addition, it takes a certain amount of time to raise the water temperature to the temperature required for sterilization, so the time saved in washing and disinfecting tableware is limited.

[0067] Regarding electrolysis module 4, if the cathode and anolyte products are mixed together for output, i.e., a mixed-flow structure is adopted, the actual oxidation-reduction potential of the output electrolytic product often fails to meet expectations due to the consumption of the anolyte by the cathode product, resulting in insufficient sterilization and disinfection effects. Given these drawbacks, to avoid the consumption of the anolyte by the cathode product, existing technologies often output the cathode and anolyte products separately. While this structure can guarantee the oxidation-reduction potential of the output anolyte, it still requires additional operations such as discarding and storing the cathode product, leading to water waste.

[0068] Therefore, to ensure the disinfection capability of the output electrolysis products, the electrolysis space of the electrolysis module 4 in this application is divided into a cathode chamber 404 with a cathode 403 and an anode chamber 402 with an anode 401 by a first separator 405. The inlet 411 and outlet 412 of the electrolysis space are both located on the anode chamber 402 side. After the raw water enters the electrolysis space through the inlet 411, it first participates in electrolysis at the anode 401, and then the generated hydrogen ions and other cations cross the first separator 405 into the cathode chamber 404, where they continue to participate in electrolysis at the cathode 403. Therefore, the first separator 405 needs to be configured as an ion channel for cations to achieve transmembrane transport of hydrogen ions and other cations.

[0069] Example 1: Optimize the structure of electrolysis module 4 to improve the redox potential of the anode product.

[0070] like Figure 6-9 As shown, in this embodiment, the electrolysis space of the electrolysis module 4 includes a cathode chamber 404 with a cathode 403 and an anode chamber 402 with an anode 401. The cathode chamber 404 and the anode chamber 402 are separated by a first partition 405, and a water-blocking structure is provided on the first partition 405.

[0071] The inlet 411 and outlet 412 of the electrolysis space are both located on one side of the anode chamber 402.

[0072] During the electrolysis process, water flows through the inlet 411 into the anode chamber 402 and participates in electrolysis at the anode 401. The generated hydrogen ions and other cations then enter the cathode chamber 404 through the first separator 405 and continue to participate in electrolysis at the cathode 403, generating cathode products such as hydrogen gas.

[0073] The specific reaction formula is as follows:

[0074] At anode 401: 4H₂O - 4e - →O2↑+2H2O+4H + ;

[0075] Cathode 403: 2H + +2e - →H2↑;

[0076] Since no additional water inlet 411 is provided at the cathode chamber 404, and the cathode chamber 404 and the anode chamber 402 are separated by the first partition 405, the water volume in the cathode chamber 404 is limited during the electrolysis process. To prevent the cathode 403 from burning dry during the electrolysis process, a first gap 407 is provided between the first partition 405 and the peripheral wall of the electrolysis space in this application. The cathode chamber 404 and the anode chamber 402 are connected through the first gap 407, so that the water flow in the anode chamber 402 can enter the cathode chamber 404 through the first gap 407. This part of the water flow can prevent the cathode 403 from burning dry.

[0077] The inventors unexpectedly discovered that although the cathode chamber 404 and the anode chamber 402 are connected through the first gap 407, and the cathode products can diffuse into the anode chamber 402 through the first gap 407, causing consumption of the anode products, the actual output oxidation-reduction potential of the electrolytic products of this invention is still improved compared with the mixed flow structure.

[0078] The inventors speculate that because the electrolysis module 4 of this invention does not have an additional water inlet 411 in the cathode chamber 404, and the cathode chamber 404 and the anode chamber 402 are separated by the first separator 405, the amount of water in the cathode chamber 404 is limited during electrolysis. Due to the limited water volume, only a small portion of the hydrogen generated at the cathode 403 dissolves in the water and diffuses into the anode chamber 402 through the first gap 407 with the water flow, causing unnecessary consumption of the anode product; the majority of the remaining hydrogen diffuses into the anode chamber 402 in a gaseous state through the first gap 407. Compared with hydrogen dissolved in water, the probability of gaseous hydrogen reacting with the liquid anode product is smaller. Therefore, most of this hydrogen is directly discharged through the water outlet 412, thus resulting in a significant increase in the redox potential of the output electrolysis product even though this invention outputs the electrolysis product in a similar mixed-flow manner. In the mixed-flow structure, since the amount of water in the cathode chamber 404 is relatively large or can be replenished in time, most of the hydrogen generated at the cathode 403 is dissolved in the water. The dissolved hydrogen has a high probability of contacting the anode products, thus causing more consumption of the anode products and limiting the redox potential of the output electrolysis products.

[0079] On the other hand, after the gaseous hydrogen is discharged through the outlet 412 of the electrolysis module 4, it can diffuse into the external environment on its own without any additional treatment. Therefore, this invention greatly improves the redox potential of the output electrolysis product without adding any steps to the process, achieving unexpected technical results.

[0080] Furthermore, it should be noted that the first partition 405 with a water-blocking structure in this utility model can limit most of the water flow in the anode chamber 402 from diffusing into the cathode chamber 404. However, since the hydrogen ions and other cations generated at the anode 401 need to pass through the first partition 405 to enter the cathode chamber 404 and continue to participate in electrolysis, and water is required as a medium during the migration of ions, the first partition 405 can allow ions to carry some water through during the migration process. This water can also prevent the cathode 403 from burning dry during the electrolysis process.

[0081] The first separator 405 can function as a water barrier and allow cations to pass through. If the first separator 405 allows hydrogen to diffuse across the membrane, since the hydrogen generated during the electrolysis process exists in the form of hydrogen negative ions, and since hydrogen negative ions have an extra electron, they are more active and have a higher probability of diffusing into the anode chamber 402 and reacting with the anode products. Therefore, it may still cause unnecessary consumption of the anode products.

[0082] Therefore, in this embodiment, the first partition 405 is preferably also provided with a gas check structure to restrict hydrogen from directly diffusing through the first partition 405 into the anode chamber 402.

[0083] Because of the gas check valve structure, the hydrogen anions generated during electrolysis in this embodiment can only diffuse into the anode chamber 402 through the first gap 407. Since hydrogen anions are relatively active, they lose excess electrons during diffusion into the first gap 407, transforming into inactive hydrogen gas. Even if this hydrogen gas diffuses into the anode chamber 402, the probability of it reacting with the anode products is low. Therefore, by providing a gas check valve structure on the first separator 405, the unnecessary consumption of anode products can be further reduced, thereby further improving the redox potential of the output electrolytic products.

[0084] Specifically, when all other electrolysis conditions are the same, the redox potential of the output electrolysis product of this invention can be increased from 700mV in mixed-flow mode to 820mV.

[0085] The first separator 405 may be a cation exchange membrane, a polytetrafluoroethylene (PTFE) composite membrane, a multilayer hydrophobic coating membrane, or other structural forms.

[0086] The working principle of the polytetrafluoroethylene composite membrane is to disperse the perfluorosulfonic acid membrane in the porous polytetrafluoroethylene framework, and to use the hydrophobicity and density of polytetrafluoroethylene to block various gases, including hydrogen.

[0087] The working principle of the multilayer hydrophobic coating membrane is to coat the surface of the cation exchange layer with an ultrathin polyvinylidene fluoride layer to block liquid water and gas from passing through.

[0088] Considering that cations such as hydrogen ions enter the cathode chamber 404 through the first separator 405 and continue to participate in electrolysis at the cathode 403, the closer the cathode 403 is to the first separator 405, the smaller the voltage required to drive ion migration. Therefore, the cathode 403 is preferably disposed in close contact with the first separator 405.

[0089] When the cathode 403 is installed in close contact with the first partition 405, a second gap 408 needs to be provided between the cathode 403 and the peripheral wall of the cathode chamber 404. The second gap 408 is connected to the first gap 407 to ensure that the hydrogen generated at the cathode 403 can enter the anode chamber 402 through the second gap 408 and the first gap 407, and be discharged through the outlet 412.

[0090] Alternatively, with the cathode 403 and the first separator 405 in close contact, the cathode 403 and the first separator 405 can be adjusted to be in a gap configuration, that is, a second gap 408 is still left between the cathode 403 and the first separator 405. In this case, the hydrogen gas generated at the cathode 403 can enter the anode chamber 402 through the second gap 408 and the first gap 407 between the cathode 403 and the first separator 405.

[0091] It should be noted that in this embodiment, there is a difference between gap setting and interval setting. Gap setting leaves a gap between the two while keeping them in close contact, and the size of the gap is small. Interval setting, on the other hand, makes the distance between the two more obvious.

[0092] Due to the limited size of the second gap 408, the rate at which hydrogen diffuses from the cathode chamber 404 to the anode chamber 402 is relatively slow. Hydrogen accumulates continuously in the cathode chamber 404, its volume increasing until it impacts the first partition 405, causing it to bulge out towards the anode chamber 402. Therefore, in this embodiment, it is preferable to provide second gaps 408 between the cathode 403 and the peripheral wall of the cathode chamber 404, and between the cathode 403 and the first partition 405, to ensure the diffusion rate of hydrogen and reduce its impact on the first partition 405.

[0093] Since hydrogen ions enter the cathode chamber 404 through the first separator 405, if the area of ​​the cathode 403 is equal to the area of ​​the first separator 405, the hydrogen ions only contact the cathode 403 on the side facing the first separator 405 and cannot be utilized on the other side of the cathode 403, resulting in low utilization of the cathode 403. Alternatively, if a second gap 408 is provided between the cathode 403 and the peripheral wall of the cathode chamber 404, although the cathode chambers 404 on both sides of the cathode 403 can be connected through the second gap 408, allowing water flow to participate in electrolysis at the cathode 403 on the side away from the first separator 405, the diffusion rate of hydrogen to the cathode chamber 404 on the other side of the cathode 403 is slow due to the size limitation of the second gap 408. Most of the hydrogen generated during electrolysis still accumulates between the first separator 405 and the cathode 403, causing a greater impact on the first separator 405.

[0094] Therefore, in this embodiment, the area of ​​the cathode 403 is preferably smaller than the area of ​​the first separator 405. For example, multiple cathodes 403 are spaced apart, or at least one first diffusion hole is provided through the cathode 403. In this case, hydrogen ions entering the cathode chamber 404 through the first separator 405 can enter the cathode chamber 404 on the other side of the cathode 403 through the gap between adjacent cathodes 403 or the first diffusion hole, and participate in electrolysis at the cathode 403 on the side away from the first separator 405, thus utilizing the cathode 403 at this location. On the other hand, the cathode chamber 404 at this location can also be used to contain hydrogen gas that has not yet diffused into the anode chamber 402, so as to reduce the impact of hydrogen gas on the first separator 405 and extend the service life of the first separator 405.

[0095] Furthermore, compared to cathodes 403 with multiple spaced intervals, providing a first diffusion hole on cathode 403 allows cathode 403 to remain as a single unit, resulting in better stability and easier assembly.

[0096] Furthermore, to limit the cathode 403 and create a gap between it and the first separator 405, a conductive element 413 is provided in the cathode chamber 404 in this embodiment. The conductive element 413 has a hollow frame structure to provide space for hydrogen gas. One side of the conductive element 413 is attached to the cathode 403, and the opposite side is attached to the inner wall of the cathode chamber 404 to support the cathode 403. For easy connection, the conductive element 413 extends outward through the peripheral wall of the cathode chamber 404, with a conductive end.

[0097] In the above embodiment, the hydrogen generated at the cathode 403 can be output to the anode chamber 402 due to the second gap 408. However, due to the size limitations of the second gap 408 and the first gap 407, the output efficiency of the hydrogen is slow. Therefore, the hydrogen in the cathode chamber 404 will cause greater pressure on the first partition 405.

[0098] In this embodiment, the anode 401 needs to be closely attached to the first partition 405 so that the anode 401 can limit the first partition 405 from another direction. At this time, a third gap 409 needs to be provided between the anode 401 and the peripheral wall of the anode chamber 402, and the third gap 409 is connected to the first gap 407 so that the hydrogen in the cathode chamber 404 can diffuse into the anode chamber 402 and finally be discharged through the outlet 412.

[0099] And / or, in this embodiment, the anode 401 and the first separator 405 can be adjusted to be spaced apart while being tightly attached. A third gap 409 can be provided between them, and the third gap 409 is connected to the first gap 407. At this time, the anode 401 can still limit the first separator 405 from another direction, thereby offsetting the pressure of hydrogen on the first separator 405.

[0100] If the area of ​​the anode 401 is equal to the area of ​​the first separator 405, considering that the anode 401 needs to limit the first separator 405, the two are set close together or a third gap 409 is left. The water flow in the anode chamber 402 on the side away from the first separator 405 participates in electrolysis at the anode 401 to generate hydrogen ions. However, the generated hydrogen ions cannot pass through the first separator 405 due to the obstruction of the anode 401 and continue to participate in electrolysis at the cathode 403. They can only go around from the first gap 407 to the cathode 403 to continue to participate in electrolysis. As the ion migration path increases, the voltage required for electrolysis increases accordingly.

[0101] Therefore, in this embodiment, the area of ​​the anode 401 is preferably smaller than the area of ​​the first separator 405, so that the hydrogen ions generated at the anode 401 can pass through the first separator 405 and continue to participate in electrolysis at the cathode 403 along a shorter path.

[0102] For example, multiple anodes 401 can be provided, with adjacent anodes 401 spaced apart, or at least one second diffusion hole can be provided through anode 401. Compared with multiple spaced anodes 401, providing a second diffusion hole on anode 401 allows anode 401 to remain a single unit, resulting in better stability and easier installation.

[0103] Furthermore, to limit the position of the anode 401, the electrolysis module 4 in this embodiment has a conductive element 413 with a frame structure on the side of the anode 401 away from the first separator 405. The conductive element 413 is hollow to accommodate the water flow participating in electrolysis. One side of the conductive element 413 abuts against the anode 401, and the opposite side abuts against the inner wall of the anode chamber 402 to support the anode 401. To facilitate electrical connection, the conductive element 413 extends outward through the peripheral wall of the anode chamber 402, with a conductive end.

[0104] Example 2: The structure of electrolysis module 4 is further optimized by setting a hydrogen outlet in the cathode chamber.

[0105] Although the above embodiments reduce the probability of hydrogen reacting with the anode products, some water-soluble hydrogen still diffuses into the anode chamber 402 through the first gap 407, causing consumption of the anode products.

[0106] Therefore, as Figure 3 and Figure 4 As shown, in this embodiment, instead of the first gap 407 for hydrogen evacuation, a hydrogen outlet 406 is provided at the cathode chamber 404, which connects the cathode chamber 404 to the outside of the anode chamber 402. By directly discharging the hydrogen, the consumption of hydrogen for the anode products is further reduced. Correspondingly, to ensure that the hydrogen is discharged through the hydrogen outlet 406 and to prevent its transmembrane diffusion, the first separator 405 also needs to be provided with a gas check structure to block the hydrogen.

[0107] The first separator 405 can be configured as an ultrafiltration membrane, a hydrophilic cation exchange membrane, a negatively charged nanofiltration membrane, or a mixed matrix membrane, etc., which allows water to flow through while blocking the diffusion of hydrogen generated at the cathode 403 across the membrane.

[0108] The hydrophilic cation membrane adsorbs water molecules through hydrophilic groups such as sulfonic acid groups to form a hydration layer, providing a transport channel for cations and water. Non-polar gas molecules are blocked because they cannot form hydrogen bonds or electrostatic interactions with the hydration layer, thus achieving the function of gas anti-reverse flow.

[0109] Negatively charged nanofiltration membranes have a negatively charged surface, and their pore size can block gases while allowing cations and water to pass through. By incorporating hydrophilic groups, a dynamic hydration layer can be formed, enhancing water transport. Gases, due to their hydrophobicity, nonpolarity, and low solubility, are trapped, thus achieving a gas anti-reverse function.

[0110] The hybrid matrix membrane uses organic polymers as the matrix and inorganic nanomaterials such as zeolite and metal-organic frameworks (MOFs) are uniformly dispersed inside. The surface charge and hydrophilicity of the materials can promote the transport of cations and water, and the gas anti-reverse function can be achieved by controlling the pore size distribution.

[0111] Furthermore, to prevent the remaining reducing substances in the cathode products from diffusing into the anode chamber 402 with the water flow, the first separator 405 is preferably provided with a water-blocking structure. It should be noted that while the first separator 405 can limit the diffusion of most of the water flow from the anode chamber 402 into the cathode chamber 404, since cations such as hydrogen ions generated at the anode 401 need to pass through the first separator 405 to enter the cathode chamber 404 and continue participating in electrolysis, and water is required as a medium during ion migration, the first separator 405 can allow ions to carry some water through during migration. This water can also prevent the cathode 403 from drying out during electrolysis.

[0112] Specifically, the first separator 405 can be configured as a cation exchange membrane, a hydrophobic MOF (metal-organic framework) membrane, a hydrophobic COF (covalent organic framework) membrane, or a hydrophobic mixed matrix membrane, etc. This configuration allows hydrogen ions to carry some water into the cathode chamber 404, preventing the cathode 403 from burning dry, while also preventing the cathode products from consuming the anode products. The cation exchange membrane is preferably a proton exchange membrane.

[0113] Hydrophobic MOF and COF membranes form low surface energy interfaces by introducing hydrophobic functional groups such as fluorinated groups, which block the permeation of polar water molecules and gases; their pore surfaces are modified with negatively charged groups to promote cation migration.

[0114] The hydrophobic hybrid matrix membrane uses hydrophobic polymers such as polyvinylidene fluoride as the matrix and embeds hydrophilic inorganic nanoparticles such as zeolite and sulfonated carbon nanotubes. It forms a continuous ion transport channel through hydrophilic fillers, allowing cations and their hydrated ions to pass through, while preventing gas diffusion across the membrane through the hydrophobic matrix.

[0115] When all other electrolysis conditions are the same, the redox potential of the output electrolysis product in this embodiment can be increased from 820mV in the above embodiment to more than 1000mV.

[0116] As hydrogen ions carry water into the cathode chamber 404, to prevent water from overflowing from the hydrogen outlet 406, a gas-liquid separation unit such as a polytetrafluoroethylene membrane can be installed at the hydrogen outlet 406. This ensures that the hydrogen outlet 406 only outputs hydrogen, while the water is trapped in this chamber. Even as the chamber fills with water, the electrolysis reaction can still proceed normally. When hydrogen ions carry water into this chamber, the original water flow within the chamber flows back to the anode 401 to participate in electrolysis. Therefore, in this embodiment, most of the water flow can participate in electrolysis at the anode 401.

[0117] In existing technologies, ion exchange channels such as cation exchange membranes are often installed between the cathode chamber 404 and the anode chamber 402 to prevent the diffusion of cathode products across the membrane and the unnecessary consumption of anode products, thus creating a structure that outputs cathode and anode products separately. However, due to the selectivity of the ion exchange membrane, even if the water flow in the cathode chamber 404 participates in electrolysis, the generated hydroxide ions cannot enter the anode chamber 402. Therefore, in this structure, the water flow entering the cathode chamber 404 does not participate in electrolysis; it only dissolves the cathode products and prevents the electrode from drying out. Because this portion of the water flow does not participate in electrolysis, the conversion ratio between the required electrolysis products and the influent is low. In other words, although this structure avoids the consumption of anode products, the actual amount of anode products generated is relatively small.

[0118] This embodiment overcomes the technical bias in the prior art. Under the premise of avoiding the consumption of anode products by cathode products, most of the raw water for electrolysis can participate in electrolysis at anode 401, which fully improves the conversion ratio of electrolysis products to influent, and ensures the utilization rate of water resources.

[0119] Example 3: Improving electrode utilization by setting up a water-blocking component 410.

[0120] Due to the ease of electrode fabrication, electrodes in existing technologies often employ a sheet-like structure. For sheet-like electrodes, the inlet 411 and outlet 412 typically form a straight line. Water flowing into the electrolysis space through the inlet 411 often flows directly out through the outlet 412 along the shortest path. For portions of the electrode farther from the inlet 411 and outlet 412, the water flow often fails to cover them. This results in these portions of the electrode not fully participating in electrolysis, thus wasting electrode area. Furthermore, because the water flows out through the outlet 412 along the shortest path, the electrolysis time is correspondingly shorter, and the actual output electrolysis product's performance often fails to meet expectations.

[0121] Therefore, as Figure 5 As shown, to prevent the electrodes at the corners from failing to fully participate in electrolysis, at least one water-blocking element 410 is provided in the anode chamber 402 in this embodiment. The water-blocking element 410 divides the initial water path between the inlet 411 and the outlet 412 into several interconnected second flow paths 414. Since the width of the second flow path 414 is smaller than the width of the initial water path, the water flow is guided through the second flow path 414, allowing the water flow to cover a larger area of ​​the anode 401, thus significantly improving the utilization rate of the anode 401.

[0122] If only one water-blocking component 410 is provided, in order to ensure the utilization rate of the anode 401, the second flow paths 414 on both sides of the water-blocking component 410 can be evenly distributed. At this time, the width ratio of the second flow path 414 to the initial water path is 0.5. Therefore, in this embodiment, the width ratio of the second flow path 414 to the initial water path is less than or equal to 0.5.

[0123] When several water-blocking components 410 are provided, adjacent second flow paths 414 are connected by a transition section, which is U-shaped. At this time, the connected second flow paths 414 extend the flow path of the electrolyzed raw water. Under the guidance of the second flow paths 414, the water flow can fully cover all areas of the anode 401, thereby improving the utilization rate of the anode 401.

[0124] In addition to limiting the width of the second flow path 414, in this embodiment, the length ratio of any water-blocking component 410 to the length of the anode 401 is greater than or equal to 0.5, so as to ensure the extension length of the second flow path 414, so that it can cover more area of ​​the anode 401, and avoid the second flow path 414 being too short, resulting in the transition section being too wide, which would prevent the water flow from fully covering the anode 401 when it flows through the transition section.

[0125] On the other hand, in order to further increase the area of ​​the anode 401 covered by the water flow, in this embodiment the water inlet 411 of the electrolysis module 4 is located at the end of the second flow path 414 away from the transition section, so that the electrolyzed raw water can cover the area of ​​the anode 401 from the water inlet 411 to the transition section.

[0126] And / or, in this embodiment, the outlet 412 of the electrolysis module 4 is located at the end of the second flow path 414 away from the transition section, so that the water flow can cover the area of ​​the anode 401 from the outlet 412 to the transition section.

[0127] Alternatively, to increase the utilization rate of the electrode, the anode 401 can be configured as at least part of the peripheral wall of the anode chamber 402, that is, one side of the anode 401 is the anode chamber 402, and the other side is the first partition 405; and the anode 401 can be configured to form a semi-closed or closed enclosure for the electrolyzed raw water in the anode chamber 402. The cathode chamber 404 is correspondingly fitted outside the anode chamber 402.

[0128] When the anode 401 forms a closed enclosure around the electrolyzed raw water in the anode chamber 402, the anode 401 becomes tubular, and its internal hollow area is the anode chamber 402. This structural form fully guarantees the electrolysis area when the volume of the electrolysis module 4 is limited.

[0129] At the normal inlet flow rate for daily water use, the raw water for electrolysis enters the anode chamber 402 in a turbulent manner. Under the influence of the turbulent and irregular flow field, the raw water for electrolysis continuously impacts the anode 401 surrounding it and participates in electrolysis. Therefore, under this structural configuration, the utilization rate of the anode 401 and the electrolysis efficiency can still be guaranteed.

[0130] Furthermore, the electrolyzed water sterilization dishwasher in this embodiment is also equipped with a humidity-sensitive element to control the start and stop of the electrolysis module 4.

[0131] Specifically, when water passes through the electrolysis module 4, as the humidity increases, the humidity-sensitive element automatically controls the control circuit of the electrolysis module 4 to conduct electrolysis on the water flowing through it; when water does not pass through the electrolysis module 4, as the humidity decreases, the humidity-sensitive element automatically controls the control circuit of the electrolysis module 4 to turn off to prevent the electrodes inside from drying out.

[0132] By incorporating a humidity-sensitive element, the starting efficiency of the electrolysis module 4 can be fully guaranteed while avoiding dry burning, thus ensuring thorough disinfection of the tableware in the washing chamber 1.

[0133] Example 4: Optimize the position of the electrolysis module 4 to ensure the disinfection effect of the spray arm 301 on the tableware.

[0134] The electrolysis module 4 uses water as the electrolysis raw material, so it needs to be placed in the water flow path. In this embodiment, the electrolysis module 4 can be placed at least one location on the water inlet pipe 2, the washing chamber 1, or the circulation pipe 3.

[0135] When only one electrolysis module 4 is installed, if it is placed on the water inlet pipe 2, the water will no longer participate in electrolysis after entering the washing chamber 1. If there are many bacteria in the washing chamber 1, a significant amount of the electrolysis products will be consumed, and the remaining products may not be sufficient to disinfect the tableware. Therefore, the electrolysis module 4 is preferably installed on the washing chamber 1 or the circulation pipe 3, so that it is electrolyzed multiple times during water circulation to fully ensure the disinfection ability of the washing water.

[0136] In this embodiment, to achieve water recycling, a water collection area 101 is provided at the bottom of the washing chamber 1. One end of the circulation pipe 3 is connected to the water collection area 101 through the first outlet 102, and the other end is a spray arm 301 installed in the washing chamber 1. When the electrolysis module 4 is installed in the washing chamber 1, it is preferably installed in the water collection area 101.

[0137] Under the action of water pump 302 in the circulating water line, the water in the water collection area 101 is drawn into the circulating pipe 3 through the first outlet 102, and then pumped onto the tableware through the spray arm 301 to rinse, wash and disinfect the tableware. Then the washing water flows back into the water collection area 101, and enters the circulating pipe 3 under the action of water pump 302 for the next cycle.

[0138] Considering that the electrolysis module 4 can electrolyze the water flow around it, and the electrolysis products diffuse with the water flow to water flows farther away from the electrolysis module 4, the electrolysis module 4 is preferably located in the water collection area 101, near the first outlet 102, to avoid the water pump 302 drawing water from the water collection area 101 that has not yet participated in electrolysis, thus ensuring that the tableware is thoroughly disinfected.

[0139] Alternatively, the electrolysis module 4 can be directly installed on the circulation pipeline 3.

[0140] Specifically, to ensure thorough washing of the tableware, the circulation pipe 3 in this embodiment is equipped with at least two spray arms 301 to rinse the tableware from different directions. Correspondingly, to enable communication between the water collection area 101 and the multiple spray arms 301, the circulation pipe 3 includes a main pipe 303 connected to the water collection area 101 and several branch pipes 304 corresponding to the spray arms 301.

[0141] When the electrolysis module 4 is installed on branch line 304, to ensure that the water flow from any spray arm 301 can rinse and disinfect the tableware, an electrolysis module 4 needs to be installed on each branch line 304, which increases the manufacturer's production cost. Therefore, the electrolysis module 4 is preferably installed on the main line 303. After the washing water in the collection area 101 enters the circulation pipe 3, it must enter any branch line 304 through the main line 303. That is, the water flow sprayed by the spray arm 301 is water that has participated in electrolysis and carries electrolysis products, which can thoroughly rinse and disinfect the tableware. After the washing process is completed, the washing wastewater is discharged through the drain pipe 5. During the drainage process, if the water flow still carries electrolysis products, it can also disinfect the floor drain and prevent bacteria growing there from contaminating the kitchen environment.

[0142] On the other hand, the inventors discovered that with the electrolysis module 4 of this invention, the water sprayed from the spray arm 301 can not only rinse and clean the tableware, but also emulsify the oil stains attached to it. That is, by using the electrolysis module 4 of this invention, the process of using high-temperature water to disinfect the tableware is saved; the process of using high-temperature water to activate the detergent is also saved. Therefore, by using the electrolysis module 4 of this invention, while ensuring the cleaning and disinfection effect on the tableware, the process of heating the washing water is also saved, greatly shortening the washing time and saving the energy consumption corresponding to heating the washing water.

[0143] The inventors speculate that the reason why the electrolytic products with high redox potential have the function of emulsifying oils is because: (1) The electrolytic products of this application have strong oxidizing properties, and the main component of edible oil is triglycerides. The electrolytic products preferentially oxidize unsaturated fatty acids such as oleic acid and linoleic acid, resulting in the breakage of ester bonds and the generation of hydrophilic products such as glycerol, fatty acid fragments and peroxides, which can be carried away with the water flow. (2) During the process of ozone in the electrolytic products decomposing into oxygen, the formed microbubbles adhere to the surface of the oil, thereby achieving the effect of emulsifying oils.

[0144] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
