Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and relates to washing machines, specifically to a washing machine that utilizes water electrolysis. Background Technology

[0002] As people's living standards continue to improve, consumers are paying increasing attention to a healthy home environment. As an important component of home appliances, users have higher and higher demands for washing machines; in addition to basic clothes cleaning functions, the need for efficient sterilization and disinfection functions is becoming increasingly prominent. Therefore, integrating a sterilization device into washing machines has become one of the standard features in current product designs.

[0003] Common sterilization methods for washing machines in the prior art mainly include high-temperature sterilization, ultraviolet sterilization, and anion sterilization, but all of them have certain limitations. Among them, (1) high-temperature sterilization achieves sterilization by heating water, which consumes a lot of energy and is not suitable for clothing materials that are not resistant to high temperatures, such as silk and chemical fibers; (2) ultraviolet (UV) sterilization has blind spots and is difficult to cover all areas inside the drum, resulting in incomplete sterilization; (3) silver ion sterilization has broad-spectrum antibacterial properties, but there is a risk of heavy metal residue, and long-term use may have potential impacts on human health and the environment.

[0004] In recent years, water electrolysis technology has shown great promise in the washing machine field due to the high oxidation-reduction potential of its anode products, which exhibit strong, broad-spectrum, and residue-free bactericidal performance. Compared with the aforementioned sterilization methods, water electrolysis undoubtedly has advantages such as low energy consumption, environmental friendliness, and comprehensive sterilization, but it still has certain problems. (1) Scale is easily formed during water electrolysis. With the accumulation of scale, not only does it reduce the electrolysis efficiency and lead to a worse sterilization effect, but it also shortens the service life of the electrolysis electrodes, requiring users to frequently replace the electrolysis module, resulting in high maintenance costs and a poor user experience. (2) The existing electrolysis module structure faces the following technical contradictions: (a) In the mixed output mode of anode and cathode products, the anode products in the output liquid will be neutralized by the cathode products, resulting in the oxidation-reduction potential still not reaching the expected level, and the sterilization effect will be affected; (b) In the separate output mode of cathode and anode products, although a higher oxidation-reduction potential can be achieved to ensure the sterilization effect, the cathode will produce waste liquid, which not only causes serious waste of water resources, but also significantly increases the amount of sewage generated, increasing the cleaning burden on users.

[0005] Although existing technologies propose descaling through "polarity reversal" (i.e., polarity reversal), there are no reports on how to achieve self-cleaning of the electrolysis module without generating waste liquid and high redox potential. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a washing machine that utilizes electrolyzed water to solve the technical problem that existing washing machines using electrolyzed water for sterilization cannot simultaneously achieve reverse descaling, efficient sterilization, and zero waste liquid discharge.

[0007] To achieve the above-mentioned technical objectives, according to one aspect of the present invention: a washing machine utilizing water electrolysis is provided, comprising a washing drum, at least one water supply passage connected to the washing drum, and an electrolysis module disposed on the water supply passage. The electrolysis module has an electrolysis space within its housing, and the electrolysis space is divided into a first chamber provided with a first electrode and a second chamber provided with a second electrode by a first separator. The first electrode and the second electrode have opposite polarities and their polarities can be switched.

[0008] The first separator is an ion channel for cations;

[0009] The first chamber is provided with a first water inlet pipe and a first water outlet pipe, and the second chamber is provided with a second water inlet pipe and a second water outlet pipe, with the first water inlet pipe and the second water inlet pipe arranged in parallel;

[0010] When the electrode of any chamber is the anode, the water inlet and outlet pipes of the current chamber are connected, and the water inlet pipes of the adjacent chambers are shut off.

[0011] By installing an electrolysis module in the water supply path, the raw water entering the module is transformed into electrolyzed water with highly efficient sterilization capabilities through an electrochemical reaction during its flow. This electrolyzed water possesses strong oxidizing properties and broad-spectrum bactericidal activity, enabling in-situ disinfection of the water supply path and the interior of the washing drum and other wet flow paths, effectively inhibiting the growth of bacteria, mold, and other microorganisms. This fundamentally solves the problems of pipe contamination, drum odor, and secondary contamination of clothes caused by long-term humid environments in existing technologies. Simultaneously, during the washing process, this electrolyzed water can also be used as the main washing medium to directly participate in washing clothes, achieving simultaneous cleaning and sterilization.

[0012] When either the first or second electrode is the anode, the inlet and outlet water pipes of that chamber are open, while the inlet water pipes of adjacent chambers are closed. Through this design, external water enters the anode chamber and participates in electrolysis at the anode, generating hydrogen ions and other cations. Simultaneously, the hydrogen ions and other cations generated on the anode side migrate to the cathode chamber under the influence of the electric field through the ion channels. Since ion migration requires water molecules as carriers (i.e., accompanied by the diffusion of hydrated ions), a small amount of water enters the cathode chamber, sufficient to maintain the humid environment required for the cathode reaction, preventing "dry burning" and ensuring stable hydrogen evolution at the cathode. By switching the polarity of the first and second electrodes, the original cathode chamber can be transformed into the anode chamber, its internal environment becoming acidic. This allows deposited scale to dissolve under acidic conditions and be discharged with the water flow. This process achieves self-cleaning of the electrolysis module, effectively preventing scale accumulation, restoring and maintaining electrolysis efficiency, and extending the service life of the electrolysis module.

[0013] More importantly, since the vast majority of the raw water is supplied only to the anode chamber for electrolysis, the generation efficiency of electrolytic products per unit volume of water is significantly improved, meaning the conversion ratio of the electrolyzed raw water is greatly increased. Furthermore, because the cathode chamber is not directly fed with raw water, no large amount of waste liquid is generated, fundamentally avoiding the burden of manually emptying the waste liquid for users, thus improving ease of use and hygiene safety. Therefore, the washing machine utilizing electrolyzed water described in this application effectively solves the technical problem in existing electrolyzed washing machines that cannot simultaneously achieve reverse electrode descaling, efficient sterilization, and zero waste liquid discharge.

[0014] Furthermore, the water supply path is a water supply pipeline connecting an external water source and a washing drum, and the electrolysis module is installed on the water supply pipeline.

[0015] Furthermore, the water supply passage includes a water supply pipe connecting an external water source to the washing drum and an internal circulation pipe connected to the washing drum. The outlet of the internal circulation pipe is located above its inlet, which is used to draw water from the bottom of the drum up and spray it back onto the clothes, instead of letting the water just stay at the bottom and soak the clothes.

[0016] The electrolysis module is installed on the water supply pipeline and / or the internal circulation pipeline.

[0017] When the electrolysis module is installed in the water supply line, it can electrolyze the raw water during the inlet stage to generate electrolyzed water with cleaning, sterilization, and stain removal functions. This significantly enhances the rinsing effect and sterilization function during the rinsing stage. When the electrolysis module is installed in the internal circulation line, it can continuously electrolyze the circulating water during the washing process. This design helps to further enhance the antibacterial and deodorizing effects.

[0018] Furthermore, it also includes a commutation circuit, which is electrically connected to the electrolysis module to switch the polarity of the first electrode and the second electrode.

[0019] By setting up a reversing circuit, the polarity of the electrodes can be actively reversed during the electrolysis process, thereby triggering the reverse electrode descaling mechanism: when scale accumulates to a certain extent in the original cathode chamber, the polarity is switched to make the chamber become the anode chamber, and its internal environment becomes acidic, which promotes the dissolution of scale such as calcium hydroxide and magnesium hydroxide under acidic conditions and discharges it with the electrolyte, thus realizing the self-cleaning of the electrolysis module.

[0020] Furthermore, both the first and second water outlet pipes are in a conductive state; the first partition is equipped with a gas check valve structure.

[0021] Furthermore, the first electrode, the first separator, and the second electrode are stacked, and the area of ​​the first separator is larger than the area of ​​any one of the electrodes.

[0022] In this structural configuration, the outlet pipe on one side can be used to output the anode products, while the outlet pipe on the other side outputs the hydrogen generated at the cathode, thereby ensuring the smooth progress of the electrolysis reaction.

[0023] Furthermore, the first chamber and the second chamber are connected, and the first partition is equipped with a water-blocking structure; the inlet and outlet water pipes of either chamber can be simultaneously opened or simultaneously closed.

[0024] By simultaneously opening or closing the water inlet pipes of any chamber, a relatively closed chamber is formed. Due to the water-blocking structure on the first partition, the amount of water in the closed chamber is relatively small. Because of this limited water volume, less hydrogen generated at the cathode dissolves in the water, and the probability of gaseous hydrogen reacting with the liquid anode products when diffusing to adjacent chambers 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 certain quantity of output electrolysis products.

[0025] Furthermore, a first gap is provided between the first partition and the peripheral wall of the electrolysis space, and the first chamber and the second chamber are connected through the first gap; and / or, the area of ​​the first partition is larger than the area of ​​any electrode, and at least two through holes are provided on the first partition to connect the first chamber and the second chamber.

[0026] Furthermore, a second gap is provided between the first electrode and the peripheral wall of the first chamber, and / or a second gap is provided between the first electrode and the first partition, wherein the area of ​​the first electrode is smaller than the area of ​​the first partition;

[0027] The first chamber is connected to the second chamber through a second gap.

[0028] Furthermore, a third gap is provided between the second electrode and the peripheral wall of the second chamber, and / or a third gap is provided between the second electrode and the first partition, wherein the area of ​​the second electrode is smaller than the area of ​​the first partition;

[0029] The second chamber is connected to the first chamber through a third gap.

[0030] Furthermore, both the first electrode and the second electrode are provided with a plurality of diffusion holes, and the diffusion holes of the first electrode and the diffusion holes of the second electrode are symmetrically arranged on both sides of the first separator.

[0031] Considering that ions require water as a medium to migrate from the anode to the cathode, the first separator will swell during its transmembrane diffusion. This application addresses this by symmetrically arranging diffusion holes on both sides of the first separator. When the first separator swells, the ions can symmetrically expand into the diffusion holes on both sides, thereby reducing the extent of unilateral expansion and extending its service life.

[0032] After adopting the above technical solution, this application has the following beneficial effects:

[0033] 1. The washing machine utilizing water electrolysis in this application employs an electrolysis module independently developed by the inventor. It can output electrolysis products with high oxidation-reduction potential without increasing user operation steps and generating wastewater. It can also achieve self-cleaning of scale in the chamber by switching electrode polarity. It not only has good sterilization effect and saves water resources, but also extends the service life of the electrodes. It overcomes the defects in the prior art and has important practical application value.

[0034] 2. The washing machine utilizing water electrolysis of this application has the electrolysis module installed in the water supply pipeline and / or internal circulation pipeline. While meeting the user's needs for cleaning and sterilizing clothes, it can also clean and sterilize the washing machine's water inlet system, internal circulation pipeline and drum, achieving comprehensive disinfection of the entire machine's internal flow path, effectively solving the biggest pain point of "dirt and grime accumulation" in washing machines.

[0035] 3. The electrolysis module used in the washing machine using water electrolysis described in this application, by symmetrically arranging the diffusion holes of the first electrode and the second electrode on both sides of the first separator, allows the first separator to expand to both sides during the electrolysis process, reducing the extent of its expansion on one side and thus extending the service life of the first separator.

[0049] 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 of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0050] In existing washing machines, the water inlet pipes and drum are constantly in a humid environment during operation, making them highly susceptible to the growth of bacteria and mold, thus becoming a source of microbial contamination. These microorganisms may spread with the washing water or adhere to the surface of clothing, causing secondary contamination of already cleaned clothes during the washing process, seriously affecting washing performance and user health.

[0051] In view of this, this utility model provides a washing machine utilizing water electrolysis. While fully inheriting the advantages of electrolytic sterilization technology, such as environmental friendliness, high efficiency, and no residue, it innovatively solves the technical problem in existing electrolytic washing machines that it is difficult to simultaneously achieve reverse-polarity descaling, efficient sterilization, and zero waste liquid discharge. The technical solution of this utility model will be described in detail below:

[0052] Please see Figures 1 to 11 According to an embodiment of the present invention, a washing machine utilizing water electrolysis is provided, including a washing drum 12, at least one water supply passage 11 connected to the washing drum 12, and an electrolysis module 100 disposed on the water supply passage 11. The housing 1 of the electrolysis module 100 is provided with an electrolysis space, which is divided into a first chamber 2 provided with a first electrode 21 and a second chamber 3 provided with a second electrode 31 by a first separator 4. The polarities of the first electrode 21 and the second electrode 31 are opposite and can be switched.

[0053] The first separator 4 is an ion channel for cations;

[0054] The first chamber 2 is provided with a first water inlet pipe 22 and a first water outlet pipe 23, and the second chamber 3 is provided with a second water inlet pipe 32 and a second water outlet pipe 33. The first water inlet pipe 22 and the second water inlet pipe 32 are arranged in parallel.

[0055] When the electrode of any chamber is the anode, the water inlet and outlet pipes of the current chamber are connected, and the water inlet pipes of the adjacent chambers are shut off.

[0056] This invention relates to a washing machine utilizing electrolyzed water. An electrolysis module 100 is installed in the water supply passage 11, allowing the raw water entering the module to be converted into electrolyzed water with highly efficient sterilization capabilities through an electrochemical reaction during its flow. This electrolyzed water possesses strong oxidizing properties and broad-spectrum bactericidal activity. It can not only perform in-situ disinfection of the wet flow path, including the water supply passage 11 and the washing drum 12, effectively inhibiting the growth of bacteria, mold, and other microorganisms, but also fundamentally solves problems such as pipe contamination, drum odor, and secondary contamination of clothes caused by long-term humid environments in existing technologies. Furthermore, during the washing process, this electrolyzed water can also directly participate in washing clothes as the main washing medium, achieving simultaneous cleaning and sterilization.

[0057] Compared to traditional washing machines that rely on electrolyzed water and depend on high-temperature sterilization (high energy consumption, damaging to clothes), ultraviolet irradiation (with blind spots, incomplete sterilization), or silver ion release (potential heavy metal residue), which require additional time or chemical additives for sterilization, this invention achieves an integrated intelligent cleaning mode of "washing and disinfecting simultaneously" through electrolyzed water technology. It efficiently inactivates bacteria, viruses, and other harmful microorganisms without additional energy consumption or additives, significantly improving sterilization efficiency and hygiene safety during the washing process. Furthermore, electrolyzed water leaves no chemical residue after its action, making it environmentally friendly and safe, aligning with the trend of green home appliances. By integrating the electrolytic sterilization function into the water supply path, the system can operate automatically and continuously without user intervention, enhancing the overall intelligence and ease of use of the machine. It also effectively improves the dual sterilization capability of the washing machine using electrolyzed water for clothes and internal flow paths, reducing the risk of cross-infection and achieving an efficient, environmentally friendly, and sustainable cleaning experience.

[0058] Furthermore, the first water inlet pipe 22 and the second water inlet pipe 32, as well as the first water outlet pipe 23 and the second water outlet pipe 33 in the electrolysis module 100, are all connected to the water supply passage 11 in a way that can be switched on and off.

[0059] Optionally, the self-cleaning process of the electrolysis module 100 is as follows:

[0060] When the first electrode 21 is set as the anode, the second electrode 31 is set as the cathode accordingly. At this time, the first chamber 2 is the anode chamber and the second chamber 3 is the cathode chamber. After the outside water enters the anode chamber, it participates in electrolysis at the first electrode 21, i.e., the anode, to generate cations such as hydrogen ions. Then, the cations such as hydrogen ions, calcium ions, and magnesium ions pass through the first separator 4 and enter the cathode chamber on the adjacent side. The hydrogen ions continue to participate in electrolysis at the second electrode 31, i.e., the cathode, to generate hydrogen gas. The calcium ions and magnesium ions react in the cathode chamber to form scale precipitates such as calcium hydroxide and magnesium hydroxide.

[0061] Its reaction formula is:

[0062] First electrode 21, i.e., the anode: 4H₂O - 4e- →O2↑+2H2O+4H + ;

[0063] Second electrode 31, i.e., at the cathode: H2O → H + +OH - ;

[0064] Mg 2+ +2OH - =Mg(OH)2; Ca 2+ +2OH - =Ca(OH)2;

[0065] 2H + +2e - →H2↑;

[0066] After the polarity reversal operation, i.e., the first electrode 21 is adjusted to be the cathode and the second electrode 31 is adjusted to be the anode, the first chamber 2 becomes the cathode chamber and the second chamber 3 becomes the anode chamber. The scale deposits such as calcium hydroxide and magnesium hydroxide that were originally in the second chamber 3 are now in an acidic environment and react with the hydrogen ions generated during electrolysis. The specific reaction formula is as follows:

[0067] Second electrode 31, i.e., the anode: 4H₂O - 4e - →O2↑+2H2O+4H + ;

[0068] Mg(OH)2 + 2H + = 2H₂O + Mg 2+ ;Ca(OH)2+2H + = 2H₂O + Ca 2+ ;

[0069] At the first electrode 21, i.e., the cathode: H2O → H + +OH - ;

[0070] Mg 2+ +OH - =Mg(OH)2; Ca 2+ +OH - =Ca(OH)2;

[0071] 2H + +2e - →H2↑;

[0072] As can be seen from the above reaction formula, the original scale deposits such as calcium hydroxide and magnesium hydroxide in the second chamber 3 react and disappear in the acidic environment, and the calcium and magnesium ions flow out with the water flow. At this time, the environment in the second chamber 3 returns to the initial environment, and the electrolysis efficiency is thus guaranteed.

[0073] It is worth noting that in existing technologies, to avoid the consumption of anode products by cathode products in anode applications, ion exchange membranes are often used to separate the cathode and anode chambers. However, in this structure, taking cation exchange membranes as an example, even if the raw water in the cathode chamber participates in electrolysis, the generated hydroxide ions cannot diffuse across the cation exchange membrane to the anode chamber to continue participating in electrolysis. Therefore, in this structure, the raw water in the cathode chamber only serves to prevent the cathode from drying out and to dissolve hydrogen; it does not participate in electrolysis, and this water flow requires additional disposal and storage by the user. This application, however, fundamentally avoids the input of large amounts of raw water to the cathode side through a selective water supply mechanism—that is, supplying water only to the current anode chamber and closing the water inlet to the cathode chamber—thus preventing the generation of waste liquid requiring manual treatment. Simultaneously, the small amount of hydrated water carried during cation migration maintains the cathode reaction environment, which is sufficient to prevent dry burning and ensure the safe operation of the system. Therefore, this solution not only breaks through the technical prejudice of "simultaneous water supply from both chambers", but also achieves multiple goals such as efficient electrolysis, automatic descaling, and zero waste liquid discharge, significantly improving the practicality, reliability and user experience of the electrolysis module 100.

[0074] Furthermore, the washing drum 12 has a twin-drum structure. The washing drum 12 includes an inner drum (washing drum) and an outer drum (water holding drum): the inner drum is used to hold clothes and rotates during washing and spin-drying; the outer drum is used to hold washing water, support the inner drum's rotating shaft and shock absorption system; liquid can flow between the inner and outer drums to ensure that the washing water circulates between the inner and outer drums.

[0075] The washing machine of this application also includes a drain pipe and a drain valve. One end of the drain pipe is connected to the washing tub 12 for draining wastewater after washing; the drain valve is provided on the drain pipe for controlling the opening and closing of the drain passage.

[0076] Specifically, one embodiment of the washing machine utilizing water electrolysis provided by this utility model is as follows:

[0077] The electrolysis module 100 is installed on the water supply pipe 111 of the water supply passage 11. The water supply pipe 111 connects the external water source to the water inlet of the washing drum 12 so as to introduce the external water source into the washing drum 12 and realize the normal water inlet function.

[0078] When the electrolysis module 100 is installed on the water supply pipeline 111, the first inlet pipeline 22 and the second inlet pipeline 32, as well as the first outlet pipeline 23 and the second outlet pipeline 33 in the electrolysis module 100, are all connected to the water supply pipeline 111 in a way that allows for switching. This enables raw water to enter the corresponding electrolysis chamber through the water supply pipeline 111 via the inlet pipeline currently serving as the anode chamber (i.e., the first inlet pipeline 22 or the second inlet pipeline 32), achieving dynamic switching and flexible control of the water supply path. At the same time, the first outlet pipeline 23 and the second outlet pipeline 33 are also connected to the main pipeline in a way that allows for switching. The electrolyzed water generated by electrolysis can flow into the water supply pipeline 111 through the corresponding outlet pipeline, and then be transported to the washing drum 12 through the water supply pipeline 111 in sequence, achieving efficient sterilization and cleaning of the drum and clothes. During this process, thanks to the strong oxidizing power of the anode products, odor molecules adhering to clothing can also be decomposed, thereby achieving the technical effect of removing odors such as sweat and smoke.

[0079] In addition, the hydrogen produced during the cathode reaction can also be transported to the washing drum 12 through the water supply pipe 111 and discharged to the external environment through the drum body, effectively avoiding gas accumulation and ensuring the safe and stable operation of the system.

[0080] On the other hand, the washing machine utilizing electrolyzed water in this application also includes a water inlet valve, which is installed on the water supply pipe 111. By installing the water inlet valve on the water supply pipe 111, precise control of the water inlet process can be achieved, ensuring that the valve is only opened when water is needed, thus avoiding waste of water resources and abnormal leakage of the pipe.

[0081] The positional relationship between the electrolysis module 100 and the water inlet valve can be adjusted according to the actual situation.

[0082] The washing machine utilizing electrolyzed water also includes a control unit. The control unit is communicatively connected to both the water inlet valve and the electrolysis module 100, controlling their operational status. With this structure, the control unit can precisely control the opening timing and duration of the water inlet valve according to the washing program requirements, and simultaneously start or stop the electrolysis module 100, ensuring that the water flow is in an optimal electrolysis state when passing through the module, improving electrolysis efficiency and sterilization consistency. Simultaneously, the control unit can dynamically adjust the electrolysis time and intensity based on the load of clothes, the degree of soiling, or the user-selected washing mode, avoiding over-treatment of lightly soiled clothes and achieving "on-demand sterilization," effectively reducing energy consumption and water waste. Through the coordinated management of the water inlet and electrolysis processes by the control unit, the washing machine utilizing electrolyzed water can achieve an integrated cleaning process of "water inlet, electrolysis, and sterilization simultaneously," eliminating the need for additional chemical agents and truly realizing a highly efficient, environmentally friendly, and intelligent healthy washing experience.

[0083] Furthermore, the control unit controls the operation of the water inlet valve and the electrolysis module 100 according to the user's instructions.

[0084] It should be understood that washing machines utilizing water electrolysis have multiple preset washing modes, such as antibacterial washing mode, quick wash mode, drying mode, down wash mode, and self-cleaning mode. The control panel has corresponding operation options, allowing users to select the appropriate washing program based on their needs. The control unit automatically invokes the corresponding preset control program and executes the appropriate action logic based on the user's selected mode.

[0085] Specifically, after the washing program is started, the control unit first controls the water inlet valve to open and start supplying water; at the same time, it decides whether to start the electrolysis module 100 depending on whether the selected mode requires sterilization function.

[0086] For example, when a user selects the sterilization washing mode or the self-cleaning mode, the control unit automatically activates the electrolysis module 100 during the water intake stage or the subsequent rinsing stage to generate electrolyzed water with a high oxidation-reduction potential, thereby achieving efficient cleaning and sterilization of clothes, water supply pipes, and the inside of the drum. In programs with lower sterilization requirements, such as the quick wash mode, if deep sterilization is not required, the control unit can choose not to activate the electrolysis function to save energy and extend the service life of the electrolysis module 100.

[0087] In addition, the control unit monitors the water supply in real time (by obtaining signals from a water level sensor or flow meter). When the water supply reaches the preset value corresponding to the washing mode, it immediately controls the water inlet valve to close, completing the water inlet stage.

[0088] Furthermore, the washing machine utilizing water electrolysis also includes a display, which can be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display. The specific type, size, and resolution of the display are not limited, and those skilled in the art will understand that the display can be modified in terms of performance and configuration as needed. The display can be used to show the control panel of the water electrolysis washing machine or other image information. For example, the water electrolysis washing machine can display current operating information such as the type of washing program, the duration and remaining duration of the washing program, and the amount of water used.

[0089] The washing machine utilizing water electrolysis also includes a heating element, which is located upstream of the water inlet pipe of the electrolysis module 100 or on the washing drum 12. This heating element is used to heat the water. With this structural arrangement, the heating element heats the water, significantly improving the dissolution rate and dispersion performance of the detergent, preventing detergent residue, and activating its surface-active components to enhance cleaning efficiency, especially for grease and protein stains. Furthermore, warm water washing helps fibers expand, promoting the removal of dirt from clothes; simultaneously, during the rinsing stage, appropriate heating also helps dissolve and rinse away residual detergent, reducing residue and improving rinsing efficiency.

[0090] If the heating element is placed downstream of the outlet pipe of the electrolysis module 100, considering that the output anode products are more active and are more easily consumed under heating, the output electrolysis products under this structure cannot meet the user's disinfection needs. Therefore, the heating element is preferably placed upstream of the inlet pipe of the electrolysis module 100.

[0091] When the heating element is installed on the washing drum 12, it can directly heat the washing or rinsing water inside the drum 12, achieving precise control of the washing environment temperature. This heating element can take the form of an external heating jacket, an integrated heating layer within the drum, or an embedded heating element on the bottom / side wall, directly connected to the outer structure of the inner or outer drum of the washing drum 12 to ensure efficient heat transfer to the water flow inside. Since the washing drum 12 is the main container for washing water and has a relatively large volume, installing the heating element on the drum 12 allows for continuous and stable heating of the entire drum of washing or rinsing water, ensuring uniform water temperature distribution, avoiding uneven washing or fiber damage caused by localized temperature differences, and improving the consistency of washing results.

[0092] The control unit communicates with the heating element to control its operating status. When water needs to be heated, the control unit activates the heating element.

[0093] Furthermore, the control unit is communicatively connected to the drain valve and can automatically control the opening or closing of the drain valve according to the running status of the washing program (such as the end of the washing, rinsing, or spin-drying stage). When the system determines that the current washing or rinsing process is complete, the control unit issues a command to open the drain valve, discharging the wastewater in the washing drum 12 through the drain pipe; after drainage is completed, the control unit can further control the drain valve to close, preparing for subsequent water intake.

[0094] Another embodiment of the washing machine utilizing water electrolysis provided by this utility model is as follows:

[0095] like Figure 2As shown, the water supply passage 11 includes a water supply pipe 111 and an internal circulation pipe 112. The water supply pipe 111 is connected to both an external water source and the water inlet of the washing tub 12. The water supply pipe 111 is used to introduce water from the external water source into the washing tub 12 to achieve the normal water intake function. The outlet of the internal circulation pipe 112 is located above its water inlet and is used to draw water from the bottom of the tub up and re-spray it onto the clothes, instead of letting the water just stay at the bottom and soak the clothes. Correspondingly, its outlet is connected to the spray section. The water flowing out of the washing tub 12 enters the spray section through the internal circulation pipe 112, so that the water flow is re-sprayed out in an atomized, jet or other optimized form to rinse the clothes and / or the inner wall and / or door ring (door seal) of the washing tub 12 to remove foam, dirt and residue, and prevent dirt accumulation and mold. Furthermore, this circulation structure not only enables the reuse of washing liquid but also enhances the rinsing and penetration of water on clothes, improving washing uniformity and efficiency. The electrolysis module 100 can also be installed on the internal circulation pipeline 112.

[0096] When the electrolysis module 100 is installed in the water supply pipeline 111, it can electrolyze the raw water during the water intake stage to generate electrolyzed water with cleaning, sterilization, and decontamination functions. When the electrolysis module 100 is installed in the internal circulation pipeline 112, it can continuously electrolyze the circulating water. This design helps to further enhance the antibacterial and deodorizing effects.

[0097] When the electrolysis module 100 is installed on the internal circulation pipeline 112, the first water inlet pipeline 22 and the second water inlet pipeline 32, as well as the first water outlet pipeline 23 and the second water outlet pipeline 33 in the electrolysis module 100 are all connected to the internal circulation pipeline 112 in a way that can be switched on and off.

[0098] Optionally, the inlet of the internal circulation pipe 112 is connected to a separate outlet of the washing tub 12. Alternatively, the inlet of the internal circulation pipe 112 is connected to the drain outlet of the washing tub 12. The inlet of the internal circulation pipe 112 is located to one side of the inlet of the drain valve.

[0099] Furthermore, the washing machine utilizing electrolyzed water also includes a circulation pump 93, which is installed on the internal circulation pipe 112. The circulation pump 93 is used to provide power to ensure that washing water or rinsing water can be effectively drawn from the washing drum 12 and delivered to the spray section through the internal circulation pipe 112, thereby realizing the recycling of water.

[0100] Furthermore, the washing machine that utilizes electrolyzed water also includes a filter element, which is installed at the water inlet of the internal circulation pipe 112 to filter impurities such as fiber lint, dirt particles, and residual detergent.

[0101] The washing machine utilizing water electrolysis also includes: a water inlet valve, a first control valve, and a control unit. The water inlet valve is located on the water supply pipe 111; the first control valve is located on the internal circulation pipe 112; and the control unit is communicatively connected to the water inlet valve, the first control valve, and the electrolysis module 100, respectively, and is used to control the operating status of the water inlet valve, the first control valve, and the electrolysis module 100. With this structural arrangement, by setting the water inlet valve on the water supply pipe 111, precise control of the water inlet process can be achieved, ensuring that the valve is only opened when water is needed, avoiding water waste and abnormal pipe leakage. Simultaneously, the first control valve on the internal circulation pipe 112 allows for independent regulation of the water flow towards the spray section. This first control valve can open during spray or circulating washing programs, allowing water to enter the internal circulation pipe and be sprayed into the washing drum via the spray section; while it closes during non-spray stages, blocking the water flow path and preventing unnecessary water circulation or backflow, further optimizing system operating efficiency.

[0102] Furthermore, the control unit can precisely control the opening timing and duration of the water inlet valve and the first control valve according to the washing program requirements. Simultaneously, it synchronously starts or stops the electrolysis module 100, ensuring that the water flow is in the optimal electrolysis state when passing through the module, improving electrolysis efficiency and sterilization consistency. At the same time, the control unit can dynamically adjust the electrolysis time and intensity according to the load of clothes, the degree of soiling, or the user-selected washing mode, avoiding over-treatment of lightly soiled clothes and achieving "on-demand sterilization," effectively reducing energy consumption and water waste. Through the coordinated management of the water inlet and electrolysis processes by the control unit, washing machines utilizing electrolyzed water can achieve an integrated cleaning process of "water inlet, electrolysis, and sterilization simultaneously," eliminating the need for additional chemical agents and truly realizing a highly efficient, environmentally friendly, and intelligent healthy washing experience.

[0103] When the electrolysis module 100 is installed on the internal circulation pipeline 112, the electrolysis module 100, the circulation pump 93 and the first control valve are spaced apart, and the positions of the electrolysis module 100, the circulation pump 93 and the first control valve can be adjusted according to the actual situation.

[0104] Furthermore, the control unit is communicatively connected to the circulation pump 93 to control the operating status of the circulation pump 93.

[0105] Furthermore, the control unit controls the operating status of the water inlet valve, the first control valve, the circulating pump 93, and the electrolysis module 100 according to the user's instructions or preset programs.

[0106] It should be understood that washing machines utilizing water electrolysis have multiple preset washing modes, such as antibacterial washing mode, quick wash mode, drying mode, down wash mode, and self-cleaning mode. The control panel has corresponding operation options, allowing users to select the appropriate washing program based on their needs. The control unit automatically invokes the corresponding preset control program and executes the appropriate action logic based on the user's selected mode.

[0107] Specifically, when the electrolysis module 100 is installed on the internal circulation pipe 112, after the washing program is started, the control unit first controls the water inlet valve to open and inject external water into the washing drum to complete the initial water inlet stage.

[0108] Once the washing process begins, the system intelligently determines whether to open the first control valve, the circulation pump 93, and start the electrolysis module 100 based on the preset program or actual washing needs to execute the spraying process.

[0109] When spraying or intensive washing is required, the control unit activates the first control valve and the circulation pump 93, allowing the washing water in the washing tub 12 to enter the spray section through the internal circulation pipe 112. Simultaneously, the control unit determines whether to activate the electrolysis module 100 to electrolyze the circulating water flow according to the program settings. This control method achieves on-demand linkage between the electrolysis function and the spraying process, improving the efficiency of water and electricity utilization and enhancing the intelligence and adaptability of the washing process.

[0110] Optionally, when it is a pulsator washing machine, the spray section includes an annular water chamber provided at the loading and unloading port of the washing drum 12. The water inlet of the annular water chamber is connected to the internal circulation pipe 112. The annular water chamber is provided with multiple spray nozzles or spray holes, and each spray nozzle or spray hole is spaced apart and all face the inside of the washing drum 12.

[0111] Optionally, when it is a drum washing machine, the spray section includes a spray head. The spray head is disposed on a sealing ring located at the loading / unloading port of the washing drum 12 and extends through the sealing ring into the interior of the washing drum 12 to achieve directional spraying of clothes or drum walls. By placing the spray head on the sealing ring near the loading / unloading port, the front area of ​​the drum (i.e., near the door seal) can be directly rinsed, effectively removing residual foam, dirt, and detergent, preventing mold growth, and improving the cleanliness of the drum. Furthermore, during the initial washing or rinsing stage, the spray head can pre-wet the clothes or directly spray detergent solution, helping the detergent to dissolve quickly and distribute evenly, thus improving the washing efficiency.

[0112] Specifically, such as Figure 10 and Figure 11As shown, the washing machine utilizing water electrolysis also includes a reversing circuit 6, which is electrically connected to the electrolysis module 100 and switches the polarity of the first electrode 21 and the second electrode 31. With this structural arrangement, the reversing circuit 6 can actively control the reversal of electrode polarity during electrolysis, thereby triggering a reverse-polarity descaling mechanism: when scale accumulates to a certain extent in the original cathode chamber, the polarity is switched, transforming the chamber into an anode chamber, making its internal environment acidic. This causes scale such as calcium hydroxide and magnesium hydroxide to dissolve under acidic conditions and be discharged with the electrolyte, achieving self-cleaning of the electrolysis module 100.

[0113] Furthermore, the washing machine utilizing water electrolysis also includes second control valves corresponding to the first water inlet pipe 22, the first water outlet pipe 23, the second water inlet pipe 32, and the second water outlet pipe 33, respectively, to control the opening and closing of the first water inlet pipe 22, the first water outlet pipe 23, the second water inlet pipe 32, and the second water outlet pipe 33.

[0114] Furthermore, the first embodiment of the commutation circuit 6 provided by this utility model is as follows: Figure 10 As shown, the commutation circuit 6 is used to output the signal current for switching the electrodes of the electrolytic module 100. It includes a first relay KR1, a second relay KR2, a diode D3, a double-control switch 61, a transistor Q1, a first inductor, and a second inductor. The first relay KR1 and the second relay KR2 are respectively connected to the double-control switch 61, which controls the switching of the electrodes. One end of the first relay KR1 and the second relay KR2 are connected in series, and the other end of the first relay KR1 is connected to the power supply. The other end of the second relay KR2 is connected to the collector of the transistor Q1. One end of the first inductor is connected to the relay unit, and the other end is connected to the transistor Q1. The emitter of the transistor Q1 is grounded. One end of the second inductor is connected to the other end of the first inductor, and the other end is grounded to the emitter of the transistor Q1. The diode D3 is connected in parallel with the circuit formed by the first relay KR1 and the second relay KR2. The diode D3 is used to prevent backflow of current from the power supply or the relay unit, which could damage the components in the commutation circuit.

[0115] The signal current output by the relay unit enters the base of transistor Q1 through the first inductor, making transistor Q1 open-circuited. At this time, the first relay KR1 and the second relay KR2 are energized, opening the double-control switch 61. The current changes smoothly through the first inductor. After the relay unit stops outputting the signal current, the second inductor outputs current in reverse to the base of transistor Q1, making the current decrease smoothly. The double-control switch 61 smoothly transitions to the switching output current of the electrolytic module 100.

[0116] The dual-control switch 61 includes a first single-pole double-throw switch JK1, a second single-pole double-throw switch JK2, and an electrode power supply. One end of the first single-pole double-throw switch JK1 is connected to one end of the filter unit, and the other end can switch between the positive and negative terminals of the electrode power supply. One end of the second single-pole double-throw switch JK2 is connected to the other end of the filter unit, and the other end can switch between the positive and negative terminals of the electrode power supply. A first relay KR1 controls the first single-pole double-throw switch JK1, and a second relay KR2 controls the second single-pole double-throw switch JK2. The output current switching is stable and reliable through the combination of the two single-pole double-throw switches.

[0117] Furthermore, a second embodiment of the commutation circuit 6 provided by this utility model is as follows: Figure 11 As shown, the commutation circuit 6 is used to output the signal current for switching the electrodes of the electrolytic module 100. It includes a contactor KM1, a diode D3, a double-control switch 61, a transistor Q1, a first inductor, and a second inductor. The first contactor KM1 is connected to the double-control switch 61, which controls the switching of the electrodes. One end of the contactor KM1 is connected to the power supply, and the other end is connected to the transistor Q1. The emitter of the transistor Q1 is grounded. One end of the second inductor is connected to the other end of the first inductor, and the other end is grounded to the emitter of the transistor Q1. The circuit formed by the diode D3 and the contactor KM1 is connected in parallel. The diode D3 is used to prevent backflow of current from the power supply or from the relay unit, which could damage the components in the commutation circuit.

[0118] When it is necessary to switch electrodes, the controller 62 outputs a signal, and the current enters the base of the transistor Q1 through the first inductor, making the transistor Q1 open. At this time, the contactor KM1 is energized and the double-control switch 61 is opened. The current changes smoothly through the first inductor. After the relay unit stops the signal current output, the second inductor outputs current in reverse to the base of the transistor Q1, so that the current decreases smoothly. The double-control switch 61 smoothly transitions to the switching output current of the electrolysis module 100.

[0119] The dual-control switch 61 includes a first single-pole double-throw switch JK1, a second single-pole double-throw switch JK2, and an electrode power supply. One end of the first single-pole double-throw switch JK1 is connected to one end of the power supply of the electrolysis module 100, and the other end can switch between the positive and negative poles of the electrode power supply. One end of the second single-pole double-throw switch JK2 is connected to the other end of the power supply of the electrolysis module 100, and the other end can switch between the positive and negative poles of the electrode power supply. The contactor KM1 controls the first single-pole double-throw switch JK1 and the second single-pole double-throw switch JK2. The output current switching is stable and reliable through the combination of the two single-pole double-throw switches.

[0120] The first embodiment of the electrolysis module 100 provided by this utility model is as follows:

[0121] like Figure 3 and Figure 4 As shown, the first chamber 2 and the second chamber 3 are separated by the first partition 4. In this structure, in order to facilitate the smooth discharge of hydrogen, both the first water outlet pipe 23 and the second water outlet pipe 33 are in a conductive state.

[0122] Specifically, when the first inlet pipe 22 is open, the first outlet pipe 23 is used to output electrolysis products, and the second outlet pipe 33 is used to output hydrogen.

[0123] When the second water inlet pipe 32 is turned on, the first water outlet pipe 23 is used to output hydrogen gas, and the second water outlet pipe 33 is used to output electrolysis products.

[0124] To prevent hydrogen from diffusing across the membrane into adjacent chambers via the first separator 4 and consuming the anode products, a gas check structure is provided on the first separator 4, which can effectively prevent hydrogen from passing through while allowing cation migration.

[0125] Optionally, the first separator 4 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 flow while permitting the passage of cations, and simultaneously blocks the diffusion of hydrogen gas generated at the cathode across the membrane.

[0126] Hydrophilic cation membranes adsorb 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.

[0127] Negatively charged nanofiltration membranes have a negatively charged surface. Their pore size can block gases, while cations and water can pass through. By incorporating hydrophilic groups, a dynamic hydration layer can be formed, enhancing water transport. Gases are trapped due to their hydrophobicity, nonpolarity, and low solubility, thus achieving a gas anti-reverse function.

[0128] 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.

[0129] Furthermore, in order to prevent the reducing substances in the cathode chamber from diffusing into the anode chamber with the water flow and causing consumption of the anode products, a water-blocking structure is preferably added to the first partition 4 in this embodiment.

[0130] It should be noted that although the first separator 4 in this invention can limit most of the water flow in the anode chamber to diffuse into the cathode chamber, since the hydrogen ions and other cations generated at the anode need to pass through the first separator 4 to enter the cathode chamber and continue to participate in electrolysis, and water is required as a medium during the migration of ions, the first separator 4 can allow ions to carry some water through during the migration process. This water can also prevent the cathode from burning dry during the electrolysis process.

[0131] Therefore, the first separator 4 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.

[0132] This structural design allows hydrogen ions to carry some water into the cathode chamber, preventing the cathode from burning dry, while also preventing the cathode products from consuming the anode products. The cation exchange membrane is preferably a proton exchange membrane.

[0133] 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.

[0134] 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.

[0135] Experimental data show that, under the premise that other electrolysis conditions are the same, the oxidation-reduction potential (ORP) of the electrolysis product output in this embodiment can be increased from 820mV in the previous embodiment to more than 1000mV, which significantly enhances the bactericidal ability of electrolyzed water.

[0136] On the other hand, in order to reduce the voltage required for electrolysis in this embodiment, the first electrode 21, the first separator 4 and the second electrode 31 are preferably stacked, and the area of ​​the first separator 4 is larger than the area of ​​any electrode. That is, a number of diffusion holes 5 are provided on the first electrode 21 and the second electrode 31 to further shorten the migration path of hydrogen ions.

[0137] Furthermore, in order to extend the service life of the first separator 4, the diffusion holes 5 of the first electrode 21 and the diffusion holes 5 of the second electrode 31 are preferably symmetrically arranged on both sides of the first separator 4 to reduce the unilateral swelling amplitude of the first separator 4.

[0138] The second embodiment of the electrolysis module 100 provided by this utility model is as follows:

[0139] Although the electrolysis space is divided into a first chamber 2 and a second chamber 3 by the first separator 4, the first chamber 2 and the second chamber 3 are connected, and the water flow in one chamber can diffuse to the other chamber. In order to prevent the water from flowing directly out through the outlet pipe on the other side, the outlet pipe needs to be shut off. That is, in this embodiment, the inlet pipe and outlet pipe of any chamber need to be opened or closed at the same time.

[0140] Furthermore, a water-blocking structure is provided on the first partition 4.

[0141] Through the above structural design, the inventors unexpectedly discovered that although the interconnection between the first chamber 2 and the second chamber 3 causes the cathode products to diffuse into the anode chamber, resulting in some consumption of the anode products, the electrolysis module 100 of this application can still significantly improve the redox potential of the actual output electrolysis products compared with the traditional mixed flow structure, thereby ensuring the sterilization capability of the output electrolysis products.

[0142] In response, the inventors speculate that although the electrolysis module 100 of this application only connects the water inlet pipe on the anode chamber side, and the first chamber 2 and the second chamber 3 are separated by the first partition 4, limiting the amount of water in the cathode chamber during electrolysis, due to the limited water volume, only a small portion of the hydrogen generated at the cathode dissolves in the water and diffuses into the anode chamber with the water flow, causing unnecessary consumption of the anode products; the majority of the remaining hydrogen diffuses into the anode chamber in a gaseous state. Compared with hydrogen dissolved in water, gaseous hydrogen has a lower probability of reacting with liquid electrolysis products. Therefore, most of this hydrogen is directly discharged through the water outlet pipe of the anode chamber, thus ensuring that even if the electrolysis module 100 outputs electrolysis products in a mixed-flow manner, the redox potential of the output electrolysis products is still significantly improved. In contrast, in the traditional mixed-flow structure, since there is a large amount of water in the cathode chamber or it can be replenished in time, most of the hydrogen generated at the cathode dissolves in the water. The hydrogen dissolved in the water has a high probability of coming into contact with the anode products, thus causing more consumption of the anode products and resulting in a greater limitation on the redox potential of the output electrolytic products.

[0143] On the other hand, the gaseous hydrogen gas, after being discharged through the water outlet pipe, can diffuse on its own without requiring additional treatment. Therefore, this invention significantly improves the redox potential of the output electrolysis products without adding any steps to the process, achieving unexpected technical results.

[0144] Furthermore, it should be noted that the first partition 4 with a water-blocking structure in this invention can limit most of the water flow in the anode chamber to diffuse into the cathode chamber. However, since the hydrogen ions and other cations generated at the anode need to pass through the first partition 4 to enter the cathode chamber and continue to participate in electrolysis, and water is required as a medium during the migration of ions, the first partition 4 can allow ions to carry some water through during the migration process. This water can also prevent the cathode from burning dry during the electrolysis process.

[0145] Furthermore, since the first separator 4 has a water-blocking function while allowing cations to pass through, if its structure allows hydrogen to diffuse across the membrane in gaseous form, it may bring new problems. Specifically, the hydrogen generated during electrolysis exists in the form of hydrogen anions. These ions have high chemical activity due to carrying extra electrons, and can easily pass through the first separator 4 into the anode chamber, where they react with the anode products, resulting in the ineffective consumption of the anode products.

[0146] To address the aforementioned issues, this embodiment preferably incorporates a gas check valve structure on the first separator 4 to restrict the direct diffusion of hydrogen across the membrane into the anode chamber. This structural design ensures that the hydrogen generated during electrolysis can only diffuse directionally, rather than permeate randomly. During this process, hydrogen anions lose excess electrons and transform into inactive hydrogen molecules. Even if this hydrogen enters the anode chamber, it is less likely to react with the anode products, further reducing unnecessary losses of the anode products and increasing the redox potential of the output electrolysis products.

[0147] Experimental data show that, under the premise that other electrolysis conditions are the same, the redox potential of the electrolysis product output by the present invention can be increased from about 700mV in the traditional mixed flow mode to more than 820mV, which significantly enhances the bactericidal ability of electrolyzed water.

[0148] As an optional solution, the first separator 4 can be implemented using a cation exchange membrane, a polytetrafluoroethylene (PTFE) composite membrane, a multilayer hydrophobic coating membrane, or other structural materials. Wherein:

[0149] Polytetrafluoroethylene composite membranes effectively block the penetration of various gases, including hydrogen, by dispersing perfluorosulfonic acid membranes within a porous PTFE framework and utilizing its excellent hydrophobicity and density.

[0150] Multilayer hydrophobic coating membranes are made by coating an ultrathin polyvinylidene fluoride (PVDF) coating on the surface of the cation exchange layer, forming a dual barrier against liquid water and gas.

[0151] Regarding the connection method between the first chamber 2 and the second chamber 3, as follows: Figure 5-9As shown, the first chamber 2 and the second chamber 3 can be connected by setting a first gap 41 between the first separator 4 and the peripheral wall of the electrolysis space;

[0152] Alternatively, if the area of ​​the first partition 4 is larger than the area of ​​any electrode, the first chamber 2 and the second chamber 3 can be connected by directly providing a through hole on the first partition 4. In this connection method, the through hole is preferably provided along the edge of the first partition 4, avoiding its placement between the first electrode 21 and the second electrode 31, so as to smoothly connect the first chamber 2 and the second chamber 3. On the other hand, the number of through holes is at least two, so as to achieve the effect of one inlet and one outlet.

[0153] Since the electrode polarity of the electrolysis module 100 of this application can be switched, the first chamber 2 can be either an anode chamber or a cathode chamber.

[0154] When the first chamber 2 is the anode chamber, the second chamber 3 is the cathode chamber. Hydrogen gas in the cathode chamber needs to diffuse into the anode chamber and is eventually discharged through the outlet pipe at the anode chamber. Due to the limited diffusion rate, hydrogen gas in the cathode chamber may gradually accumulate, its volume continuously increasing, eventually impacting the first separator 4 and causing it to bulge towards the anode chamber. Therefore, the first electrode 21 is preferably disposed close to the first separator 4 to limit the bulging tendency of the first separator 4 and extend its service life.

[0155] When the first chamber 2 is the cathode chamber and the second chamber 3 is the anode chamber, the second electrode 31 in the second chamber 3 is preferably disposed close to the first partition 4 to limit the tendency of the first partition 4 to expand into the second chamber 3 and extend its service life.

[0156] Therefore, the first electrode 21, the first separator 4, and the second electrode 31 are preferably stacked. In this arrangement, the distance between the first electrode 21 and the second electrode 31 is shorter, requiring a lower voltage for the driving ions to migrate between the two electrodes, thus saving energy. Specifically, conductive elements 7 can be respectively provided in the first chamber 2 and the second chamber 3. The conductive elements 7 can support the electrodes, realizing the stacked structure of the electrodes and the first separator 4. Furthermore, the conductive elements 7 extend outwards through the peripheral wall of the electrolysis space to facilitate electrode connection.

[0157] On the other hand, when the inlet pipe of any chamber is open, the electrolyzed raw water enters the chamber and participates in electrolysis at the anode to generate hydrogen ions. If the anode is a single unit, the hydrogen ions need to bypass the anode under the action of voltage to enter the adjacent chamber and continue to participate in electrolysis at the cathode. In this case, the movement path of the hydrogen ions is longer and the voltage required for electrolysis is larger.

[0158] Therefore, as Figure 8 and Figure 9 As shown, in this embodiment, a plurality of diffusion holes 5 are preferably provided through the anode, so that the electrolyzed hydrogen ions can directly enter the adjacent chamber through the diffusion holes 5 and the first separator 4, and continue to participate in electrolysis at the cathode. Considering that this application is adapted to an electrolysis module 100 with reverse polarity, both the first electrode 21 and the second electrode 31 can be anodes. Therefore, both the first electrode 21 and the second electrode 31 need to be provided with a plurality of diffusion holes 5. After providing diffusion holes 5, the electrode area is reduced, and the area of ​​the first separator 4 is larger than the area of ​​any electrode.

[0159] On the other hand, for the cathode electrode, hydrogen ions are generated into hydrogen gas at the cathode. The hydrogen gas can diffuse through the diffusion hole 5 into the cathode chamber on the side of the cathode away from the first separator 4, thus preventing the accumulated hydrogen gas from continuously impacting the first separator 4 and causing it to expand towards the anode chamber.

[0160] Furthermore, considering that ions require water as a medium during migration, the first separator 4 will swell during its transmembrane diffusion. In this embodiment, by symmetrically arranging the diffusion holes 5 on both sides of the first separator 4, the ions can symmetrically expand into the diffusion holes 5 on both sides when the first separator 4 swells, thereby reducing the extent of unilateral expansion and extending its service life.

[0161] Regarding the connection between the first chamber 2 and the second chamber 3, a second gap 24 may be provided between the first electrode 21 and the peripheral wall of the first chamber 2, and / or a second gap 24 may be provided between the first electrode 21 and the first partition 4, and the second gap 24 may be connected to the chamber space on the side of the electrode away from the first partition 4 through the diffusion hole 5.

[0162] The first chamber 2 is connected to the first gap 41 through the second gap 24, or to the through hole on the first partition 4, and finally to the second chamber 3.

[0163] Correspondingly, a third gap 34 may also be provided between the second electrode 31 and the peripheral wall of the second chamber 3, and / or a third gap 34 may be provided between the second electrode 31 and the second partition, the third gap 34 being connected to the chamber space on the side of the electrode away from the first partition 4 through the diffusion hole 5.

[0164] The second chamber 3 is connected to the first gap 41 through the third gap 34, or to the through hole on the first partition 4, thus achieving communication with the first chamber 2.

[0165] On the other hand, considering that any chamber may be a cathode chamber, in order to ensure the diffusion rate of hydrogen, preferably, a second gap 24 is provided between the first electrode 21 and the peripheral wall of the first chamber 2 and between the first electrode 21 and the first partition 4.

[0166] Furthermore, a third gap 34 is provided between the second electrode 31 and the peripheral wall of the second chamber 3, and between the second electrode 31 and the first partition 4.

[0167] The third embodiment of the electrolysis module 100 provided by this utility model is as follows:

[0168] In existing technologies, electrodes are typically sheet-like structures for ease of processing. With such structures, a straight path often forms between the inlet and outlet, causing water entering the electrolysis space through the inlet to flow directly out through the outlet along the shortest path. For electrodes farther from the inlet and outlet, the water flow often fails to reach them. This results in those electrodes not fully participating in electrolysis, leading to a waste of electrode area. Furthermore, because the water flows out through the outlet along the shortest path, the electrolysis time is correspondingly shorter, and the actual output electrolysis products often fail to meet expected performance indicators.

[0169] Therefore, as Figure 7 As shown, to prevent the electrodes at corners from failing to fully participate in electrolysis, at least one water-blocking element 8 is provided in the first chamber 2 and / or the second chamber 3 in this embodiment. The water-blocking element 8 divides the initial water path between the inlet of the inlet pipe and the outlet of the outlet pipe into several interconnected second flow paths. Since the width of the second flow path is smaller than the width of the initial water path, the water flow is guided through the second flow path, allowing the water flow to cover a larger area of ​​the electrodes, thus significantly improving the utilization rate of the electrodes. On the other hand, the water-blocking element 8 also serves to support the electrodes.

[0170] Optionally, if only one water-blocking element 8 is provided, it is preferable to evenly distribute the second flow path on both sides of it. In this case, the width ratio of the second flow path to the initial water path is 0.5. Therefore, in this embodiment, it is preferable to set the ratio to ≤0.5 to ensure that the water flow fully covers the electrode surface.

[0171] Optionally, if several water-blocking components 8 are provided, adjacent second flow paths are connected by a transition section, which is U-shaped. In this case, the connected second flow paths extend the flow path of the electrolyzed raw water. Under the guidance of the second flow paths, the water flow can fully cover all areas of the electrode, thereby improving the utilization rate of the electrode.

[0172] In addition to limiting the width of the second flow path, in this embodiment, the length of any water-blocking component 8 is greater than or equal to the length of the electrode by 0.5, so as to ensure the extension length of the second flow path, so that it can cover more areas of the electrode, and avoid the second flow path being too short, which would make the width of the transition section too large, causing the water flow to not be able to fully cover the electrode when it flows through the transition section.

[0173] On the other hand, in order to further increase the area of ​​the electrodes covered by the water flow, in this embodiment the water inlet of the water inlet pipe is located at the end of the second flow path away from the transition section, so that the electrolyzed raw water can cover the area of ​​the electrodes from the water inlet to the transition section.

[0174] And / or, in this embodiment, the outlet of the water outlet pipe is located at the end of the second flow path away from the transition section, so that the water flow can cover the area of ​​the electrode from the outlet to the transition section.

[0175] In this invention, the electrode can be made of conductive diamond or other conductive materials, such as one or a combination of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0176] In the prior art, electrodes used for electrolysis often use precious metal electrodes such as platinum and ruthenium-iridium. Considering the limited resources of precious metals, the development prospects of such electrodes are limited. In this invention, conductive diamond electrodes are used, which reduces the dependence on precious metal resources. Considering that carbon resources for preparing conductive diamond are more abundant, this invention has better development prospects.
