Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and more particularly to dishwashers. Background Technology

[0002] With consumers becoming increasingly health-conscious and environmentally conscious, dishwashers using water electrolysis technology have emerged. These dishwashers use an electrolysis device to electrolyze ordinary tap water into alkaline and acidic water. The alkaline water has a strong ability to saponify and decompose grease, and can be used in the main washing process, replacing or reducing the use of traditional chemical dishwashing powder; while the acidic water has a better descaling function and can be used for removing scale.

[0003] For example, a device combining warm water acquisition and dishwashing functions, as described in patent number CN 216293978 U, includes a filtration module, an electrolysis device, a water tank, a heating element, and a dishwasher body. The aforementioned filtration module has a water inlet and a purified water outlet. The aforementioned electrolysis device has a water inlet connected to the purified water outlet of the aforementioned filtration module, an alkaline water outlet, and an acidic water outlet. The water inlet of the aforementioned water tank is connected to the aforementioned acidic water outlet. The aforementioned heating element is connected to the water tank through an acidic water pipe. Furthermore, the water outlet of the aforementioned heating element is connected to a drinking water pipe and a wastewater pipe. The aforementioned drinking water pipe and wastewater pipe are respectively equipped with a first solenoid valve and a second solenoid valve. The water inlet of the aforementioned dishwasher body is connected to the alkaline water outlet through an alkaline water pipe. When the electrolysis device is working, it electrolyzes ordinary tap water to produce alkaline water and acidic water. Alkaline water has a strong ability to saponify and decompose greases, so using alkaline water to clean dishes in a dishwasher can improve the cleaning effect. Acidic water has a good sterilization, disinfection and descaling function, so using acidic water can effectively remove scale from the heating element and some drinking water pipes.

[0004] Therefore, it can be seen that existing dishwashers need to be used with drinking water pipes to store and utilize acidic water. When dishwashers are not used with drinking water pipes, acidic water is usually discharged into the sewer, resulting in waste. Utility Model Content

[0005] To address the shortcomings and deficiencies in the existing technology, this invention provides a dishwasher that can store acidic water in a water storage compartment by controlling the second water circuit to disconnect, and discharge the acidic water in the water storage compartment into the washing chamber when needed, thereby achieving temporary storage and reuse of acidic water and reducing waste of acidic water.

[0006] To achieve the above-mentioned technical objectives, the dishwasher provided by this utility model includes a water inlet system and an inner tub with a washing chamber. The water inlet system includes a water storage section, a water supply path, a first water path, a second water path that can be switched on and off, and an electrolysis device for electrolyzing water to obtain acidic water and alkaline water. The water supply path is provided with an inlet valve. The electrolysis device includes a water inlet, an acidic water outlet, and an alkaline water outlet. The water inlet is connected to the outlet end of the water supply path. The alkaline water outlet is connected to the washing chamber through the first water path. The acidic water outlet is kept in communication with the water storage section. The water storage section is connected to the washing chamber through the second water path.

[0007] Preferably, the water inlet system further includes a first control valve and a second control valve, wherein the first control valve is disposed on the first water line to control the opening and closing of the first water line, and the second control valve is disposed on the second water line to control the opening and closing of the second water line.

[0008] Preferably, the water inlet system further includes a first flow meter, which is located on the water supply line and downstream of the water inlet valve.

[0009] Preferably, the water inlet system further includes a second flow meter, which is located on the first water path; or, the dishwasher further includes a water level sensor, which is located in the washing chamber to detect the water level in the washing chamber.

[0010] Preferably, the water inlet system further includes a water tank, the interior of which defines a first flow channel, a second flow channel, a third flow channel, and a water storage cavity. The first flow channel forms the first water path, the third flow channel forms the second water path, and the water storage cavity forms the water storage section. The second flow channel connects the water storage cavity with an acidic water outlet, so that acidic water flows into the water storage cavity through the second flow channel.

[0011] Preferably, both the first flow channel and the second flow channel extend from the bottom of the water tank toward the top of the water tank, with a first outlet at the top of the first flow channel and a second outlet at the top of the second flow channel.

[0012] Preferably, the water tank further defines a breathing channel communicating with the washing chamber and a fourth flow channel communicating with the breathing channel. The second water outlet is connected to the fourth flow channel, and the fourth flow channel is connected to the bottom of the water storage chamber so that acidic water flows downward into the water storage chamber through the fourth flow channel and discharges gas into the breathing channel through the fourth flow channel. The water storage chamber is provided with an overflow port communicating with the breathing channel.

[0013] Preferably, the dishwasher further includes a base, the inner tub is mounted on the base, a receiving cavity is provided between the inner tub and the base, and the electrolysis device is installed in the receiving cavity.

[0014] Preferably, the electrolysis device includes a pipe connector assembly and an electrolytic cell. The electrolytic cell is provided with a water inlet, an acidic water outlet, and an alkaline water outlet. The pipe connector assembly includes an acidic water pipe connector that is sleeved with the acidic water outlet, an alkaline water pipe connector that is sleeved with the alkaline water outlet, and a water inlet pipe connector that is sleeved with the water inlet. The acidic water pipe connector and the alkaline water pipe connector are rotatably fitted with the acidic water outlet and the alkaline water outlet, respectively.

[0015] Preferably, the electrolysis device further includes a protective shell fixed to the outside of the electrolysis cell. The protective shell is connected to the pipe connector assembly to prevent the acid water pipe connector from detaching from the acid water outlet, the alkaline water pipe connector from detaching from the alkaline water outlet, and the water inlet pipe connector from detaching from the water inlet.

[0016] By adopting the above technical solution, this utility model has the following advantages: 1. During the washing and water intake process of the dishwasher of this utility model, the water inlet valve is opened, allowing water to flow to the electrolysis device through the water supply path. By opening the electrolysis device, water is electrolyzed to produce acidic and alkaline water. The alkaline water then flows into the washing chamber through the first water path, thus rinsing the dishes inside the washing chamber. Because alkaline water has excellent degreasing and stain-removing capabilities, it effectively improves the cleaning effect on the dishes. Furthermore, when acidic water is not needed, the second water path can be disconnected to temporarily store the acidic water in the water storage section. When needed, the second water path can be connected to allow acidic water in the water storage section to flow into the washing chamber, for example, for the hot rinsing stage, to sterilize and disinfect tableware and remove scale from the washing chamber. Thus, the water inlet system of this utility model forms the physical basis for simultaneously generating and separating alkaline and acidic water. This allows the two types of water to exert their maximum effectiveness at their most suitable stages. Alkaline water can be produced and used as needed, while acidic water can be stored and reused when needed, thereby improving resource utilization.

[0017] 2. The water inlet system also includes a first control valve and a second control valve. The first control valve is located on the first water path to control the opening and closing of the first water path, and the second control valve is located on the second water path to control the opening and closing of the second water path. This design allows the first control valve to control the opening and closing of the first water path. When alkaline water washing is needed, opening the first control valve opens the first water path, allowing the generated alkaline water to flow into the washing chamber. When alkaline water is not needed, closing the second control valve prevents water in the washing chamber from flowing back into the electrolysis device through the first water path. The second control valve controls the opening and closing of the second water path. Especially when both the first and second control valves are solenoid valves connected to the control unit, manual operation is unnecessary, achieving intelligent control of the water inlet system.

[0018] 3. The water inlet system also includes a first flow meter, which is located on the water supply line and downstream of the inlet valve. This design allows the first flow meter to detect the water flow rate in the water supply line, thus enabling real-time monitoring of the water entering the washing chamber. When the incoming water volume reaches a preset standard, the control system will close the inlet valve to ensure accurate water flow. Furthermore, based on the first flow meter's readings and the ratio of acidic to alkaline water, the system can calculate the amount of acidic water to be stored in the water storage compartment. When the calculated value approaches the storage compartment's capacity, the system can proactively stop water intake and electrolysis to prevent overflow. Finally, if the first flow meter still detects a water flow signal after the inlet valve is closed, it indicates a malfunction in the inlet valve or a leak in the water supply line, alerting the user for timely repairs.

[0019] 4. The water inlet system also includes a second flow meter, which is located on the first water line; alternatively, the dishwasher also includes a water level sensor, located inside the washing chamber to detect the water level. With this design, when using alkaline water for washing, the amount of alkaline water entering the washing chamber can be determined by the second flow meter or the water level sensor, ensuring that the amount of alkaline water entering the washing chamber meets the preset amount, thus avoiding insufficient alkaline water reducing the washing effect or excessive alkaline water leading to waste.

[0020] 5. The water inlet system also includes a water tank, which internally defines a first flow channel, a second flow channel, a third flow channel, and a water storage chamber. The first flow channel forms the first water path, the third flow channel forms the second water path, and the water storage chamber forms a water storage section. The second flow channel connects the water storage chamber to the acidic water outlet, allowing acidic water to flow into the water storage chamber via the second flow channel. By integrating the first water path, the second water path, and the water storage section into the water tank, the need for multiple separate piping systems can be eliminated, making the dishwasher more compact and reducing the overall size of the machine.

[0021] 6. Both the first and second flow channels extend from the bottom to the top of the water tank. The first flow channel has a first water outlet at its top, and the second flow channel has a second water outlet at its top. This design allows the water inlets of the first and second flow channels to be positioned close to the bottom of the water tank. This allows the electrolysis device to be installed below the water tank, for example, utilizing the space between the inner tub and the dishwasher base. This avoids the problem of mounting the electrolysis device on the side of the water tank, which would increase the overall lateral dimensions of the dishwasher and prevent it from being installed laterally. Furthermore, if the first water outlet were located at the bottom of the first flow channel, it would be close to the bottom of the water tank, making it easy for water in the washing chamber to flow back into the first flow channel and contaminate it. If the second water outlet were located at the bottom of the second flow channel, it would be close to the bottom of the water tank, allowing for better water flow as the water level in the storage chamber increases. Increasing water pressure leads to greater difficulty in water storage, causing fluctuations in the water output ratio between the first and second outlets, which in turn affects the pH value of the electrolyzed water. Therefore, placing the first outlet at the top of the first flow channel can effectively prevent water in the washing chamber from flowing back into the first flow channel, thus avoiding contamination of the first flow channel. This anti-contamination effect is even stronger when the first outlet is close to the top of the water tank. Placing the second outlet at the top of the second flow channel, since the second flow channel is a narrow and long water channel, has low water flow resistance, which is conducive to water storage in the storage chamber. Furthermore, placing the two outlets at the top creates conditions for adjusting the water output ratio between the two outlets.

[0022] 7. The water tank also includes a breathing channel connected to the washing chamber and a fourth flow channel connected to the breathing channel. The second outlet is connected to the fourth flow channel, which is connected to the bottom of the water storage chamber. This allows acidic water to flow downwards into the water storage chamber through the fourth flow channel and discharge gas into the breathing channel. The water storage chamber has an overflow port connected to the breathing channel. Because the electrolysis device generates gas during water electrolysis, acidic water flowing into the water storage chamber through the fourth flow channel carries some gas into the chamber, causing bubbles and abnormal noise. This solution connects the fourth flow channel to the breathing channel, allowing gas to be discharged into the breathing channel as acidic water flows through the fourth flow channel, thus reducing the amount of gas entering the water storage chamber, reducing bubble generation, and preventing abnormal noise. Furthermore, in dishwashers using a water softener, when it is necessary to discharge the hard water from the softener, the electrolysis device is closed, the third flow channel is opened, and the hard water enters the fourth flow channel after passing through the electrolysis device. The water flows into the washing chamber from the bottom of the water storage chamber. Therefore, the fourth flow channel is connected to the bottom of the water storage chamber, which can reduce the contamination of the water storage chamber by hard water. This is because when tap water is sent to the washing chamber for the washing process, the tap water will flow through the water storage chamber. If too much hard water remains in the water storage chamber, it will enter the washing chamber with the tap water, resulting in white water stains on the dishes after they dry. At the same time, the gas in the hard water can also be discharged into the washing chamber through the breathing channel, avoiding the formation of bubbles in the water storage chamber and causing abnormal noises. Finally, the water storage chamber is equipped with an overflow port connected to the breathing channel, which allows the water discharged from the overflow port to flow into the washing chamber through the drainage channel. If, due to control malfunction or calculation error, the electrolysis device continuously injects acidic water into the water storage chamber, and the third flow channel fails to open in time, the water storage chamber may become full. If it is full and acidic water continues to flow in, the tank will burst and leak into the dishwasher, causing serious malfunctions such as short circuits and structural corrosion. Therefore, an overflow port and a drainage channel are connected to allow excess water in the water storage chamber to be safely and promptly guided into the washing chamber through the overflow port and drainage channel to prevent the water tank from bursting. At the same time, the acidic water flowing into the washing chamber can also descale, sterilize, and disinfect the washing chamber, enabling reuse.

[0023] 8. The dishwasher also includes a base, with the inner tub mounted on the base. A receiving cavity is provided between the inner tub and the base, and the electrolysis device is installed in the receiving cavity. Compared to the prior art where the electrolysis device is installed on the outer wall of the inner tub, utilizing the receiving cavity between the base and the inner tub to house the electrolysis device does not increase the overall size of the dishwasher in the horizontal length direction. This allows it to fit into standard cabinet installation spaces, increasing the dishwasher's applicability and versatility, and meeting the needs of more diverse households.

[0024] 9. The electrolysis device includes a pipe fitting assembly and an electrolytic cell. The electrolytic cell is equipped with a water inlet, an acidic water outlet, and an alkaline water outlet. The pipe fitting assembly includes an acidic water pipe fitting that connects to the acidic water outlet, an alkaline water pipe fitting that connects to the alkaline water outlet, and a water inlet pipe fitting that connects to the water inlet. The acidic water pipe fitting and the alkaline water pipe fitting are rotatably fitted to the acidic water outlet and the alkaline water outlet, respectively. This design addresses the potential space constraints during actual installation of the electrolysis device. The rotatable fit between the acidic water pipe fitting and the alkaline water outlet allows for flexible adjustment of their angles based on the available space when connecting the pipes. This avoids situations where installation is impossible due to space limitations or the need for additional modifications, simplifies the piping layout and installation process, eliminates complex wiring, and improves installation efficiency.

[0025] 10. The electrolysis unit also includes a protective shell fixed to the outside of the electrolytic cell. The protective shell is connected to the pipe fitting assembly to prevent the acid water pipe fitting from detaching from the acid water outlet, the alkaline water pipe fitting from detaching from the alkaline water outlet, and the water inlet pipe fitting from detaching from the water inlet. This design, through the connection between the protective shell and the pipe fitting assembly, ensures that when the pipe fitting assembly is subjected to external force, the force applied to the pipe fitting assembly is transmitted to the protective shell, which bears and disperses part of the external force. Furthermore, since the electrolytic cell is installed within the receiving cavity, the protective shell further restricts the relative displacement between the pipe fitting assembly and the acid water outlet, alkaline water outlet, and water inlet of the electrolytic cell. This significantly improves the connection stability and reliability between the acid water outlet and the acid water pipe fitting, the alkaline water outlet and the alkaline water pipe fitting, and the water inlet and the water inlet pipe fitting, fundamentally reducing the risk of the pipe fitting assembly being pulled out and reducing safety hazards such as equipment corrosion and electrical short circuits caused by acid or alkaline water leakage.

It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Example 1

[0029] Combination Figures 1 to 13 The dishwasher provided in this embodiment includes a water inlet system and an inner tank 200 with a washing chamber. The water inlet system includes a water storage section 130, a water supply path 300, a first water path 110, a second water path 140 that can be switched on and off, and an electrolysis device 400 for electrolyzing water to obtain acidic water and alkaline water. The water supply path 300 is provided with a water inlet valve 310. The electrolysis device 400 includes a water inlet 401, an acidic water outlet 402, and an alkaline water outlet 403. The water inlet 401 is connected to the water outlet of the water supply path 300. The alkaline water outlet 403 is connected to the washing chamber through the first water path 110. The acidic water outlet 402 is kept in communication with the water storage section 130. The water storage section 130 is connected to the washing chamber through the second water path 140.

[0030] During the dishwasher's washing and water intake process, the water inlet valve 310 is opened, allowing water to flow through the water supply path 300 to the electrolysis device 400. The electrolysis device 400 electrolyzes the water to produce acidic and alkaline water. The alkaline water then flows into the washing chamber through the first water path 110, rinsing the dishes inside the washing chamber. Because alkaline water has excellent degreasing and stain-removing capabilities, it effectively improves the cleaning effect on the dishes. Furthermore, when acidic water is not needed, the second water path 140 can be disconnected, allowing the acidic water to be temporarily stored in the water storage section 130. When the program requires it, the second water path 140 can be connected to allow acidic water in the water storage section 130 to flow into the washing chamber, for example, for the hot rinsing stage, to achieve sterilization and disinfection of tableware and descaling of the washing chamber. Thus, the water inlet system in this embodiment forms the physical basis for simultaneously generating and separating alkaline water and acidic water. This allows the two types of functional water to exert their maximum effectiveness at their most suitable stages. Alkaline water can be produced and used as needed, while acidic water can be stored and reused when needed, thereby improving resource utilization.

[0031] The water inlet system in this embodiment also includes a first control valve 114 and a second control valve 141. The first control valve 114 is located on the first water passage 110 to control the opening and closing of the first water passage 110, and the second control valve 141 is located on the second water passage 140 to control the opening and closing of the second water passage 140. With this design, the first control valve 114 can control the opening and closing of the first water passage 110. When alkaline water washing is needed, opening the first control valve 114 connects the first water passage 110, allowing the generated alkaline water to flow into the washing chamber through the first water passage 110. When alkaline water is not needed, closing the second control valve 141 prevents water in the washing chamber from flowing back into the electrolysis device 400 through the first water passage 110. The second control valve 141 controls the opening and closing of the second water passage 140. Especially when both the first control valve 114 and the second control valve 141 are solenoid valves connected to the control unit, no manual operation is required, achieving intelligent control of the water inlet system.

[0032] In addition, the water inlet system also includes a first flow meter 320 and a second flow meter 115. The first flow meter 320 is located on the water supply path 300 and downstream of the inlet valve 310. This design allows the first flow meter 320 to detect the water flow rate in the water supply path 300, thus enabling real-time monitoring of the water entering the washing chamber. When the incoming water volume reaches a preset standard, the control system closes the inlet valve 310 to ensure accurate water flow. Furthermore, based on the detection results of the first flow meter 320, the system can calculate the amount of acidic water to be stored in the water storage section 130 according to the ratio of acidic to alkaline water. When the calculated value approaches the capacity of the water storage section 130, the system can actively stop water intake and water electrolysis to prevent overflow. Finally, if the first flow meter 320 still detects a water flow signal after the inlet valve 310 is closed, it indicates a malfunction in the inlet valve 310 or a leak in the water supply path 300, prompting the user to request timely repair. The second flow meter 115 is located on the first water path 110. With this design, when using alkaline water for washing, the amount of alkaline water entering the washing chamber can be obtained from the second flow meter 115, so as to ensure that the amount of alkaline water entering the washing chamber meets the preset amount, and avoid the washing effect being reduced due to insufficient alkaline water or the waste caused by excessive alkaline water.

[0033] It is understood that in other embodiments of this utility model, the dishwasher also includes a water level sensor, which is located in the washing chamber to detect the water level in the washing chamber. In this way, the amount of alkaline water entering the washing chamber can be known from the water level sensor, so as to control the amount of water entering the washing chamber.

[0034] Furthermore, the water inlet system of this embodiment also includes a water softener 500, which is located between the upstream of the electrolysis device 400 and the downstream of the inlet valve 310. Preferably, the water softener 500 is located between the first flow meter 320 and the electrolysis device 400. Since the water source contains mineral ions such as calcium and magnesium, these ions will form scale (calcium carbonate, magnesium hydroxide) when the electrolysis device 400 is working, which will quickly adhere to the electrode plates of the electrolysis device 400. This will result in the concentration (pH value) of the acidic and alkaline water produced not meeting the standards, thus greatly reducing the washing and sterilization effect. In addition, the accumulation of scale will permanently damage the electrode plates, causing the electrolysis device 400 to malfunction. Premature failure of the electrolysis unit 400 leads to high repair or replacement costs. However, the addition of a water softener 500 can remove calcium and magnesium ions from the water beforehand, supplying softened water to the electrolysis unit 400. This effectively reduces scale formation on the electrode plates, ensures long-term stability of electrolysis efficiency, and significantly extends the service life of the electrolysis unit 400. Furthermore, using softened water for electrolysis allows the electrolysis unit 400 to produce functional electrolyzed water with higher purity and more stable performance. The cleaning power of alkaline water and the bactericidal power of acidic water can both reach the optimal design level. Finally, even when the electrolysis unit 400 is turned off, washing with softened water can prevent scale from forming in the heating element, spray arm, water pipe, and washing chamber inside the dishwasher.

[0035] like Figures 2 to 8 As shown, the water inlet system in this embodiment also includes a water tank 100. The water tank 100 internally defines a first flow channel, a second flow channel 120, a third flow channel, and a water storage chamber. The first flow channel forms a first water path 110, the third flow channel forms a second water path 140, and the water storage chamber forms a water storage section 130. The second flow channel 120 connects the water storage chamber to the acidic water outlet 402, allowing acidic water to flow into the water storage chamber via the second flow channel 120. By integrating the first water path 110, the second flow channel 120, the second water path 140, and the water storage section 130 onto the water tank 100, the need for multiple separate pipes can be eliminated, making the dishwasher more compact and reducing the overall size of the machine.

[0036] In this embodiment, the water tank 100 is formed by sealing two half-shells together through hot-melt welding. Multiple partition ribs are formed inside the water tank 100, dividing the interior into multiple spaces. These multiple spaces include at least the aforementioned first flow channel, water storage chamber, and third flow channel. Figure 4 This shows a schematic diagram of the internal structure of one of the half-shells.

[0037] For clarity in the following description, the first flow channel and the first water path are both numbered 110, the third flow channel and the third water path are both numbered 140, and the water storage chamber and the water storage section are both numbered 130.

[0038] Better, such as Figure 4As shown, in this embodiment, both the first flow channel 110 and the second flow channel 120 extend from the bottom of the water tank 100 towards the top of the water tank 100. The top of the first flow channel 110 is provided with a first water outlet 111, and the top of the second flow channel 120 is provided with a second water outlet 121. This design allows the water inlet ends of the first flow channel 110 and the second flow channel 120 to be located close to the bottom of the water tank 100. This allows the electrolysis device 400 to be installed in the lower part of the water tank. For example, the space between the inner tank 200 and the dishwasher base 600 can be used to accommodate the electrolysis device 400, avoiding the situation where the electrolysis device 400 is mounted on the side of the water tank, which would increase the overall lateral size of the dishwasher and make it impossible to embed it later. In addition, if the first water outlet 111 is located at the bottom of the first flow channel 110, it will be close to the bottom of the water tank 100, and the water in the washing chamber will easily flow back into the first flow channel 110. The first flow channel 110 is contaminated. If the second outlet 121 is located at the bottom of the second flow channel 120, it will be close to the bottom of the water tank 100. As the water volume and water pressure in the water storage chamber 130 increase, the difficulty of water storage will increase, causing fluctuations in the water output ratio of the first outlet 111 and the second outlet 121, which will affect the pH value of the electrolyzed water. Therefore, placing the first outlet 111 at the top of the first flow channel 110 can effectively prevent water in the washing chamber from flowing back into the first flow channel 110, thereby preventing the first flow channel 110 from being contaminated. The anti-fouling effect is even better when the first outlet 111 is close to the top of the water tank 100. Placing the second outlet 121 at the top of the second flow channel 120 is beneficial because the second flow channel 120 is a narrow and long water channel with low water flow resistance, which is conducive to water storage in the water storage chamber 130. The top placement of the two outlets also creates conditions for the adjustable water output ratio of the two outlets.

[0039] Preferably, in this embodiment, both the first flow channel 110 and the second flow channel 120 extend from the bottom of the water tank 100 to the top of the water tank 100. This allows the first outlet 111 and the second outlet 121 to be positioned upwards. The upward positioning of the first outlet 111 increases the difficulty of water backflow from the washing chamber to the first flow channel 110, thereby effectively preventing the first flow channel 110 from being contaminated. The upward positioning of the second outlet 121 facilitates water storage in the water storage chamber 130. In this embodiment, the first outlet 111 and the second outlet 121 are at the same height. At this time, the ratio of alkaline water discharged through the first outlet 111 to acidic water discharged through the second outlet 121 is a fixed value, thereby making the amount of alkaline water produced moderate, and thus making the alkaline water preparation time moderate, the pH value of the electrolyzed water moderate, and the service life of the electrolysis device 400 moderate, which is suitable for removing general pollution.

[0040] It is understood that in other embodiments of this utility model, the first water outlet is higher than the second water outlet, which reduces the amount of alkaline water output, thereby increasing the alkaline water preparation time and the pH value of the electrolyzed water. Although the service life of the electrolysis module is reduced, the pH value of the produced alkaline water is increased, the cleaning effect is improved, and it is suitable for removing heavily polluted situations.

[0041] It is understood that in other embodiments of this utility model, the first water outlet is lower than the second water outlet, which increases the output of alkaline water, thereby shortening the alkaline water preparation time and reducing the pH value of the electrolyzed water, increasing the service life of the electrolysis device 400, but reducing the cleaning effect, which is suitable for removing light pollution.

[0042] The first control valve 114 is installed on the water tank 100. The first flow channel 110 includes a first flow section 112 and a second flow section 113. The first flow section 112 is connected to the alkaline water outlet, and the second flow section 113 is connected to the washing chamber. The first control valve 114 is located between the first flow section 112 and the second flow section 113 to control the opening and closing of the first flow section 112 and the second flow section 113. The second flow meter 115 is located in the first flow channel 110. Preferably, the second flow meter 115 is located in the second flow section 113 to improve its measurement accuracy. When only alkaline water is needed to enter the washing chamber, the first control valve 114 opens to connect the first flow section 112 and the second flow section 113, and the third flow channel 140 is disconnected. The electrolysis device 400 starts to produce alkaline water and acidic water. The alkaline water enters the first flow section 112, passes through the opened first control valve 114, enters the second flow section 113, and finally flows into the washing chamber. The second flow meter 115 monitors the water volume in real time. After reaching the preset value, it notifies the control system to close the electrolysis device 400 and the first control valve 114, while the acidic water is stored in the water storage chamber 130. When acidic water is needed to enter the washing chamber, the first control valve 114 is closed to prevent alkaline water from entering the washing chamber. At the same time, the third flow channel 140 opens, allowing the acidic water in the water storage chamber 130 to enter the washing chamber. Thus, by setting the first control valve 114 and controlling its opening and closing with the third flow channel 140, the two types of functional water can be allowed to enter the washing chamber as needed.

[0043] In addition, the water tank 100 is also defined by a breathing channel 150 and a fourth flow channel 160, that is, a breathing channel 150 and a fourth flow channel 160 are included in the multiple spaces. Breathing channel 150 is connected to washing chamber, and fourth flow channel 160 is connected to breathing channel 150. Fourth flow channel 160 is located on the side near water storage chamber 130. Second flow channel 120 and fourth flow channel 160 are located on the same side of water storage chamber 130, and second flow channel 120 is located on the side of fourth flow channel 160 away from water storage chamber 130. Second flow channel 120 and fourth flow channel 160 are connected to form an inverted U-shaped flow channel. The lower end of second flow channel 120 is connected to acidic water outlet. Second water outlet 121 is connected to fourth flow channel 160. Fourth flow channel 160 is connected to the bottom of water storage chamber 130 so that acidic water flows downward into water storage chamber 130 through fourth flow channel 160 and exhausts gas into breathing channel 150 through fourth flow channel 160. Water storage chamber 130 is provided with overflow port 131 connected to breathing channel 150. Because the electrolysis device 400 generates gas during water electrolysis, acidic water flowing into the water storage chamber 130 through the fourth flow channel 160 carries some gas into the water storage chamber 130, causing bubbles to form and resulting in abnormal noise. In this embodiment, by connecting the fourth flow channel 160 to the breathing channel 150, the gas flowing through the fourth flow channel 160 is discharged into the breathing channel 150, thereby reducing the amount of gas entering the water storage chamber 130, thus reducing bubble formation and preventing abnormal noise. Furthermore, in a dishwasher using a water softener 500 to soften water, when it is necessary to discharge the ultra-hard water from the water softener 500, the electrolysis device 400 is closed, the third flow channel 140 is opened, and the ultra-hard water enters the fourth flow channel 160 after passing through the electrolysis device 400. The water flows into the washing chamber through the bottom of the water storage chamber 130. Therefore, the fourth flow channel 160 is connected to the bottom of the water storage chamber 130, which can reduce the contamination of the water storage chamber 130 by hard water. This is because when tap water is sent to the washing chamber for the washing process, the tap water will flow through the water storage chamber 130. If too much hard water remains in the water storage chamber 130, the hard water in the water storage chamber 130 will enter the washing chamber with the tap water, resulting in white water stains on the dishes after they are dried. At the same time, the gas in the hard water can also be discharged into the washing chamber through the breathing channel 150, avoiding the generation of bubbles in the water storage chamber 130 and causing abnormal noise. Finally, the water storage chamber 130 is provided with an overflow port 131 connected to the breathing channel 150, which allows the water discharged from the overflow port 131 to flow into the washing chamber through the breathing channel 150.With this design, if the electrolysis device 400 continuously injects acidic water into the water storage chamber 130 due to control failure or calculation error, and the third flow channel 140 fails to open in time, the water storage chamber 130 may become full. If it is full and acidic water continues to flow in, it will cause the tank to burst and leak into the dishwasher body, causing serious malfunctions such as short circuits and structural corrosion. Therefore, the overflow port 131 and the breathing channel 150 are connected to allow excess water in the water storage chamber 130 to be safely and promptly guided into the washing chamber through the overflow port 131 and the breathing channel 150 to prevent the water tank from bursting. At the same time, the acidic water flowing into the washing chamber can also descale, sterilize and disinfect the washing chamber, enabling reuse.

[0044] Specifically, the fourth flow channel 160 and the water storage chamber 130 share a vertically extending common wall. This common wall is equipped with multiple first vent holes 161, which connect to the breathing channel 150 via overflow ports 131, thus establishing communication between the fourth flow channel 160 and the breathing channel 150. With this design, when acidic water carrying gas enters the fourth flow channel 160, it flows downwards into the bottom of the water storage chamber 130 due to gravity, while the gas moves upwards, entering the upper space of the water storage chamber 130 through the first vent holes 161 on the common wall. Then, it enters the breathing channel 150 via the overflow ports 131 and is finally discharged into the washing chamber. This prevents gas from accumulating in the water storage chamber 130 or pipes, ensuring stable water flow and normal system operation. Furthermore, the multiple first vent holes 161 increase the venting area of ​​the fourth flow channel 160, allowing more gas in the acidic water to be discharged, thus improving the venting effect.

[0045] In this embodiment, the overflow port 131 is located at the top of the water storage cavity 130 and is open upwards. Since the height of the overflow port 131 determines the highest water level in the water storage cavity 130, setting the overflow port 131 at the top of the water storage cavity 130 and opening it upwards can maximize the water level in the water storage cavity 130, thereby increasing the amount of acidic water that can be stored in the water storage cavity 130.

[0046] In this embodiment, the common wall includes a plurality of vertically spaced guide ribs 162, and a first vent hole 161 is formed between two adjacent guide ribs 162. Compared with setting multiple first vent holes on the common wall, which requires a complex core-pulling structure in the mold, this solution can eliminate the core-pulling structure, thereby simplifying the mold complexity and reducing manufacturing costs.

[0047] The guide rib 162 includes a guide section 1621 and a stop section 1622. The stop section 1622 extends upward from the top of the guide section 1621 and in a direction away from the fourth flow channel 160, or extends in a curved manner. This design not only enhances the structural strength of the guide rib 162, preventing deformation, but also blocks the upward splashing water flow through the stop section 1622, guiding the water flow downwards along its surface and ultimately falling back into the fourth flow channel 160. This allows gas to pass through the first vent 161 while reducing liquid flow through it, achieving more thorough gas-liquid separation. Especially in dishwashers using water softening device 500, when it is necessary to discharge the ultra-hard water from the water softening device 500, the electrolysis device 400 is closed, and the third flow channel 140 is opened. The ultra-hard water enters the fourth flow channel 160 after passing through the electrolysis device 400 and flows into the washing chamber through the bottom of the water storage chamber 130. During the downward flow of the ultra-hard water through the fourth flow channel 160, the stop section 1622 effectively prevents the ultra-hard water from entering the water storage chamber 130 through the first vent 161, thereby reducing the contamination of the inner wall of the water storage chamber 130 by the ultra-hard water and preventing the ultra-hard water from entering the washing chamber and causing white water stains on the dishes after drying.

[0048] It is understood that in other embodiments of this utility model, the common wall is a continuously arranged structure without a first exhaust port, while the upper end of the fourth flow channel is provided with a second exhaust port, which is directly connected to the right end of the breathing channel. This allows the gas in the fourth flow channel to be discharged into the washing chamber through the second exhaust port and the breathing channel. The structure is simple and can more effectively prevent hard water from entering the water storage chamber, thereby reducing the contamination of the water storage chamber by hard water.

[0049] In this embodiment, the water storage chamber 130 is located between the first flow channel 110 and the fourth flow channel 160. The lower part of the water tank 100, facing the inner liner, has a first communication port 101 with the washing chamber. The first water outlet 111 is positioned higher than the first communication port 101. The first water outlet 111 is connected to the first communication port 101 through a breathing channel 150, i.e., the breathing channel 150 is located between the first flow channel 110 and the water storage chamber 130. This design ensures that alkaline water can flow smoothly from the higher first water outlet 111 into the lower first communication port 101 and then into the washing chamber. At the same time, the water in the washing chamber cannot flow backwards beyond the height of the first water outlet 111, effectively maintaining the anti-pollution characteristics of the first flow channel 110. In addition, it also allows both normal alkaline water and overflowing acidic water to ultimately enter the washing chamber through the same first communication port 101, eliminating the need to design separate flow channels for the two water paths and greatly simplifying the interface design between the water tank and the washing chamber.

[0050] like Figure 4 and 5As shown, in this embodiment, the overflow port 131 is located at the top of the water storage cavity 130 near the end of the second flow channel 120, that is, the overflow port 131 is located at the top right end of the water storage cavity 130. The first outlet 111 is located above the top of the water storage cavity 130 near the end of the first flow channel 110, that is, the first outlet 111 is located above the top left end of the water storage cavity 130. The breathing channel 150 includes a vertically extending drainage section 151 and a horizontally extending guide section 152 located above the water storage cavity 130. The diversion section 151 is located between the first flow channel 110 and the water storage chamber 130. Its vertical extension refers to its extension from the top of the water tank 100 towards the bottom of the water tank 100. It can extend in a curved or straight manner. In this embodiment, the diversion section 151 extends in a curved manner. The lower end of the diversion section 151 is connected to the first connecting port 101, and the upper end of the diversion section 151 is connected to the first outlet 111 and one end of the guide section 152. The other end of the guide section 152 extends obliquely upward and is connected to the overflow port 131. This design allows the water discharged through the overflow port 131 to flow quickly to the diversion section 151 under the action of gravity within the guide section 152, and effectively prevents the water in the guide section 152 from flowing back into the water storage chamber 130.

[0051] In this embodiment, the top wall of the guide section 152 extends horizontally, while part of the top wall of the water storage cavity 130 arches upward to form the bottom wall of the guide section 152. The bottom wall of the guide section 152 gradually slopes downward from the overflow port 131 in a direction away from the overflow port 131. Specifically, the bottom wall of the guide section 152 includes a first inclined rib 1521 and a second inclined rib 1522 connected sequentially in a direction away from the overflow port 131. Both the first inclined rib 1521 and the second inclined rib 1522 are inclined downward in a direction away from the overflow port 131. The inclination angle of the first inclined rib 1521 is greater than that of the second inclined rib 1522, so that the first inclined rib 1521 is steeper than the second inclined rib 1522. This allows the flow area of ​​the guide section 152 to gradually increase in a direction away from the overflow port 131, guiding water to flow to the guide section 151 in a timely manner, and also increasing the difficulty of water flowing back into the water storage cavity 130.

[0052] In this embodiment, the end of the second inclined rib 1522 away from the first inclined rib 1521 extends below the first water outlet 111. The upper end of the guide section 151 is defined between the left side of the top wall of the water storage cavity 130 and the top of the first flow channel 110. The size of the upper end of the guide section 151 is larger than the size of the left end of the guide section 152, so that water can quickly enter the guide section 151 and be discharged into the washing cavity in a timely manner. It should be noted that in this embodiment, the opening of the first water outlet 111 faces downward, so as to effectively prevent water flowing from the guide section 152 to the guide section 151 from entering the first water outlet 111.

[0053] Furthermore, in this embodiment, the water tank 100 is provided with a second connecting port 102 on the wall facing the inner liner. The second connecting port 102 is located below the water storage chamber 130. The third flow channel 140 is configured in the form of a tunnel, that is, the third flow channel 140 does not pass through the second flow channel 120, but is formed in the form of a tunnel in the half shell of the tank body near the inner liner, and bypasses the second flow channel 120, so as to avoid the third flow channel 140 affecting the flow of water in the second flow channel 120. The lower end of the third flow channel 140 is provided with a flow hole connected to the second connecting port 102. The second control valve 141 is installed on the water tank 100. The second control valve 141 is used to control the opening and closing of the third flow channel 140, that is, the second control valve 141 is used to control the opening and closing of the flow hole to control the opening and closing of the third flow channel 140, thereby controlling whether the water in the water storage chamber 130 is discharged into the washing chamber. The opening and closing of the third flow channel 140 is controlled by opening and closing the second control valve 141, which is a simple structure.

[0054] In addition, the water tank 100 in this embodiment also includes a water inlet channel 170, meaning that one water inlet channel 170 is included among multiple spaces. The water inlet channel 170 is located on the side of the first flow channel 110 away from the water storage cavity 130, and the water inlet channel 170 forms part of the water supply path 300. The water inlet channel 170 includes an inlet section 171 extending from the bottom to the top of the water tank and an outlet section 172. The upper ends of the inlet section 171 and the outlet section 172 extend above the overflow port 131. The outlet section 172 is located between the inlet section 171 and the first flow channel 110. The portion of the outlet section 172 above the water storage cavity 130 is spaced apart from the portion of the top wall of the water storage cavity 130 that arches upwards, and defines the aforementioned guide section 152. An anti-siphon structure is provided between the upper end of the inlet section 171 and the upper end of the outlet section 172. The anti-siphon structure includes an upwardly arched outer arc-shaped flow channel and an inner arc-shaped flow channel. The outer arc-shaped flow channel is located outside the inner arc-shaped flow channel. One end of the outer arc-shaped flow channel is connected to the upper end of the inlet section 171, and the other end is connected to one end of the inner arc-shaped flow channel. The other end of the inner arc-shaped flow channel is connected to the upper end of the outlet section 172. The anti-siphon structure is provided with a first vent 170a (e.g., ...). Figure 7As shown in the diagram, the first vent 170a connects the breathing channel 150 and the inner arc-shaped flow channel. Since the breathing channel 150 is connected to the washing chamber, the first vent 170a can be connected to the atmosphere. With this design, when water supply to the water inlet channel 170 stops, a negative pressure will be formed upstream of the water inlet channel, causing the water stagnant downstream of the water inlet channel to tend to flow back due to siphon. Since the first vent 170a is connected to the atmosphere, air in the atmosphere can enter the water inlet channel 170 through the first vent 170a to balance the pressure difference in the water inlet channel 170, prevent siphoning in the water inlet channel 170, and thus avoid non-potable water flowing back into the water inlet channel and contaminating the water source connected to the water inlet end of the water inlet channel 170. In addition, the design of the inner arc-shaped flow channel can generate centrifugal force in the flowing water to reduce the leakage of water through the first vent 170a. Finally, in this embodiment, the first flow meter 320 is installed inside the water inlet channel 170.

[0055] Furthermore, in this embodiment, the water tank 100 also defines a drainage channel 180 and a soft water channel 190, meaning that multiple spaces include a drainage channel 180 and a soft water channel 190. The drainage channel 180 is located on the side of the water inlet channel 170 away from the water storage chamber 130. The drainage channel 180 is formed in the lower part of the water tank 100 and has a sewage inlet 181, a sewage outlet 182, and a drainage vent 183 located between the sewage inlet 181 and the sewage outlet 182. The sewage inlet 181 communicates with the washing chamber, and the sewage outlet 182 communicates with the drainage pipe. The drainage channel 180 includes an inverted U-shaped section and an extension section extending from the top of the U-shaped section to the top of the tank. The two ends of the inverted U-shaped section form the sewage inlet 181 and the sewage outlet 182, and the extension section... The top of the chamber is provided with a drain vent 183. The drain vent 183 is connected to the breathing channel 150 through a vertically extending air passage 103. The air passage 103 passes through the water inlet channel 170 and the first flow channel 110 in the form of a tunnel, without affecting the flow of water in the water inlet channel 170 and the first flow channel 110. The top of the chamber is hinged with a baffle that can open and close the drain vent 183. The baffle is located in the extension section. When the drain channel 180 generates negative pressure, the baffle opens the drain vent 183 under the action of pressure difference, so that the gas in the washing chamber enters the drain channel 180 through the breathing channel 150 and the air passage 103 to balance the pressure difference in the drain channel 180 and prevent sewage in the drain channel 180 from flowing back into the washing chamber. The soft water channel 190 is located at the bottom of the water tank and extends laterally. The soft water channel 190 is located between the lower end of the outlet section 172 and the first flow channel 110. The lower end of the outlet section 172 is connected to the inlet end of the soft water device 500. The soft water channel 190 is connected between the outlet end of the soft water device 500 and the inlet 401 of the electrolysis device 400.

[0056] It is understood that in other embodiments of this utility model, the second outlet and the overflow outlet can be directly connected, so that the water discharged from the second outlet enters the water storage chamber through the overflow outlet. This design allows acidic water to flow directly into the water storage chamber after exiting the second outlet, thus eliminating the need for a fourth flow channel connecting the second outlet and the water storage chamber. This simplifies the internal structure of the water tank and facilitates injection molding. Alternatively, the acidic water outlet can be directly connected to the water storage chamber, eliminating the need for a second and fourth flow channel, further simplifying the internal structure of the water tank.

[0057] It is understood that in other embodiments of this utility model, the water tank may be omitted, in which case the first water path and the second water path are independently set pipeline structures, and the water storage part is an independently set water storage box structure.

[0058] In addition, such as Figures 9 to 13 As shown, the dishwasher in this embodiment also includes a base 600, with the inner tub 200 mounted on the base 600. The bottom wall of the base 600 is recessed downwards to form a groove, creating a receiving cavity 001 between the inner tub 200 and the base 600. The electrolysis device 400 is installed within the receiving cavity 001. Compared to the prior art where the electrolysis device 400 is installed on the outer wall of the inner tub, utilizing the receiving cavity 001 between the base 600 and the bottom wall of the inner tub 200 to accommodate the electrolysis device 400 avoids increasing the overall size of the dishwasher in the horizontal length direction. This allows it to fit into standard cabinet installation spaces, increasing the dishwasher's applicability and versatility, and meeting the needs of more diverse user families.

[0059] The electrolysis device 400 includes a pipe fitting assembly 410 and an electrolytic cell 420. The electrolytic cell 420 is provided with a water inlet 401, an acidic water outlet 402, and an alkaline water outlet 403. The pipe fitting assembly 410 includes a water inlet pipe fitting 411 that is fitted to the water inlet 401, an acidic water pipe fitting 412 that is fitted to the acidic water outlet 402, and an alkaline water pipe fitting 413 that is fitted to the alkaline water outlet 403. The acidic water pipe fitting 412 and the alkaline water pipe fitting 413 are rotatably fitted to the acidic water outlet 402 and the alkaline water outlet 403, respectively. This design addresses the potential space constraints during the actual installation of the electrolysis unit 400. Therefore, the acid water pipe connector 412 and the alkaline water pipe connector 413 are rotatably fitted with the acid water outlet 402 and the alkaline water outlet 403, respectively. This allows for flexible adjustment of the angles of the acid water pipe connector 412 and the alkaline water pipe connector 413 according to the actual space available on site when connecting the pipes. This avoids situations where installation is impossible due to space limitations or the need for additional modifications, simplifies the pipeline layout and installation process, eliminates complex wiring, and improves installation efficiency. Furthermore, when maintenance and repair work is required on the structures surrounding the electrolysis unit 400, the rotatable fit between the acid water pipe connector 412 and the alkaline water pipe connector 413 and the acid water outlet 402 and the alkaline water outlet 403, respectively, allows the pipe connectors to be rotated as needed to adjust the pipeline to a position convenient for operators, providing more space for operation and improving the efficiency and convenience of maintenance and repair.

[0060] Preferably, the water inlet 401 and acidic water outlet 402 of the electrolysis device 400 are located on one side of the electrolysis tank 420 along its length, while the alkaline water outlet 403 is located on the opposite side. The electrolysis tank 420 is horizontally placed within the receiving cavity 001, with the positive electrode for producing acidic water and the negative electrode for producing alkaline water spaced horizontally. This allows the electrolysis device 400 to be horizontally placed within the receiving cavity 001, reducing its vertical height within the cavity and thus decreasing the depth of the recess. This allows for more space inside the dishwasher to increase the capacity of the inner drum 200, resulting in a more compact internal structure and improved practicality. When the electrolysis device 400 is installed within the receiving cavity 001, the water inlet 401 and acidic water outlet 402 are arranged side-by-side vertically on the electrolysis device 400. This installation method can relatively improve the efficiency of the electrolysis device 400 and increase the decomposition rate.

[0061] It is understood that in other embodiments of this utility model, the water inlet and the alkaline water outlet may be located on one side of the length direction of the electrolysis device, and the acidic water outlet may be located on the opposite side. In this case, when the electrolysis device is placed horizontally in the receiving cavity, the water inlet and the alkaline water outlet are arranged side by side in the vertical direction on the electrolysis device.

[0062] In this embodiment, the receiving cavity 001 includes a first receiving area for water circuit components and a second receiving area for circuit components. The first and second receiving areas are arranged side by side along the horizontal direction of the dishwasher, with the first receiving area on the left and the second receiving area on the right. The electrolysis device 400 is installed in the first receiving area to shorten the length of the connecting pipe between the electrolysis device 400 and the water tank 100. On the one hand, water circuit components come into contact with water during operation, and water has a certain degree of conductivity. If water circuit components and circuit components are installed together, water may come into contact with circuit components if a water circuit leaks, leading to safety accidents such as short circuits and leakage. Installing water circuit components and circuit components separately in the first and second receiving areas provides physical isolation, reducing the probability of circuit failure caused by water circuit leakage. On the other hand, water circuit components may generate certain electromagnetic interference to circuit components during operation, leading to signal transmission errors. Therefore, installing water circuit components and circuit components separately can reduce the impact of electromagnetic interference generated by water circuit components on circuit components, improving the stability and reliability of the circuit system. Furthermore, when a fault occurs, since the water system components and the circuit components are installed in the first and second containment areas respectively, maintenance personnel can locate the fault area more quickly, which greatly improves maintenance efficiency and reduces maintenance time and costs.

[0063] Optionally, the first and second accommodating areas are arranged side-by-side along the horizontal direction of the dishwasher.

[0064] Vibration occurs during dishwasher operation. Therefore, to prevent the electrolysis device 400 from shifting or shaking due to vibration within the dishwasher, as follows: Figure 9 and Figure 10 As shown, the bottom wall of the receiving cavity 001 is provided with a first mounting portion 610, and the electrolysis device 400 is provided with a second mounting portion 430. The first mounting portion 610 and the second mounting portion 430 are connected by fasteners, such as screws. This allows the electrolysis device 400 to be securely installed in the dishwasher, ensuring that the electrolysis device 400 remains in the working position during dishwasher operation and will not shift due to vibration, thus enhancing the stability of the installation of the electrolysis device 400.

[0065] Specifically, in this embodiment, the first mounting part 610 is a mounting post extending upward from the bottom wall of the receiving cavity 001; the second mounting part 430 is a lug extending outward from the electrolysis device 400. Fasteners pass through the lugs and are tightened onto the mounting post to fix the electrolysis device 400 in the receiving cavity 001. Two second mounting parts 430 are provided, located on opposite sides of the electrolysis device 400 in the width direction, and two corresponding first mounting parts 610 are also provided. This installation method is relatively simple and intuitive, requiring no complex tools or professional skills. During installation, simply place the electrolysis device 400 in a suitable position within the receiving cavity 001, aligning the lug with the mounting post, and then use fasteners to pass through the lugs and tighten them onto the mounting post to complete the installation. This installation method not only significantly shortens installation time and improves installation efficiency and production benefits but also ensures the stable installation of the electrolysis device 400. Furthermore, when the electrolysis device 400 needs maintenance or replacement, this installation method makes disassembly very convenient; simply loosening the fasteners is sufficient. The entire process is simple and quick, improving maintenance efficiency.

[0066] Alternatively, to facilitate the assembly and disassembly of the electrolysis device 400, the first mounting part 610 and the second mounting part 430 can be connected by snap-fit, which can also enhance the installation stability of the electrolysis device 400.

[0067] To quickly determine the installation position of the electrolysis device 400 and improve installation efficiency, a positioning element 620 is provided on the bottom wall of the receiving cavity 001. The positioning element 620 cooperates with the corresponding structure on the electrolysis device 400 to limit the installation position of the electrolysis device 400 within the receiving cavity 001.

[0068] Specifically, the positioning element 620 complements one of the corners of the electrolysis device 400. This complementary fit provides clear guidance for the installation of the electrolysis device 400 within the receiving cavity 001. During installation, the operator only needs to align the structure on the electrolysis device 400 that mates with the positioning element 620.

[0069] Finally, the electrolysis device 400 also includes a protective shell 440 fixed to the outside of the electrolysis cell 420. The protective shell 440 is connected to the pipe connector assembly 410 to prevent the acid water pipe connector 412 from detaching from the acid water outlet 402, the alkaline water pipe connector 413 from detaching from the alkaline water outlet 403, and the water inlet pipe connector 411 from detaching from the water inlet 401. This design, with the protective shell 440 connected to the pipe fitting assembly 410, ensures that when the pipe fitting assembly 410 is subjected to external force, the force applied to the pipe fitting assembly 410 is transmitted to the protective shell 440, which bears and disperses part of the external force. Furthermore, the electrolytic cell 420 is installed inside the protective shell 440, which further restricts the relative displacement between the pipe fitting assembly 410 and the acid water outlet 402, alkaline water outlet 403, and inlet 401. This significantly improves the stability and reliability of the connection between the acid water outlet 402 and the acid water pipe fitting 412, the alkaline water outlet 403 and the alkaline water pipe fitting 413, and the inlet 401 and the inlet pipe fitting 411. This fundamentally reduces the risk of the pipe fitting assembly 410 being pulled out and reduces safety hazards such as equipment corrosion and electrical short circuits caused by acid and alkaline water leakage.

[0070] In this embodiment, the protective shell 440 includes a first half-shell 441 and a second half-shell 442. The first half-shell 441 and the second half-shell 442 are aligned along the width direction of the electrolytic cell 420 and are detachably connected by a snap-fit. When the first half-shell 441 and the second half-shell 442 are aligned, a through hole 443 is formed for the acid water supply pipe connector 412, the alkaline water supply pipe connector 413, and the water inlet pipe connector 411. The through hole 443 is interference-fitted with the acid water supply pipe connector 412, the alkaline water supply pipe connector 413, and the water inlet pipe connector 411. This results in a large frictional force between the pipe connector assembly 410 and the through hole 443, which can effectively reduce the possibility of the pipe connector assembly 410 loosening or detaching during use, thereby increasing the connection stability between the pipe connector assembly 410 and the acid water outlet 402, the alkaline water outlet 403, and the water inlet 401.

[0071] In addition, the acid water pipe joint 412 and the alkaline water pipe joint 413 are also rotated with the through hole 443.

[0072] It should be explained that the water inlet 401 is actually located on one side of the electrolytic cell 420 in the height direction. After the water inlet pipe connector 411 is inserted into the water inlet 401, the water outlet end of the water inlet pipe connector 411 extends to one side of the electrolytic cell 420 in the length direction, and protrudes from the corresponding through hole 443 after the first half shell 441 and the second half shell 442 are engaged.

[0073] In this embodiment, the axes of the acidic water outlet 402 and the alkaline water outlet 403 extend along the length of the electrolytic cell 420. The corresponding acidic water pipe connector 412 and alkaline water pipe connector 413 are sleeved on the corresponding outlets along the length of the electrolytic cell 420. In order to prevent the acidic water pipe connector 412 and the alkaline water pipe connector 413 from moving outward and detaching from the corresponding outlets, in this embodiment, the portion of the acidic water pipe connector 412 and the alkaline water pipe connector 413 located inside the protective shell 440 is provided with a radially protruding limiting rib 414. The limiting rib 414 is an annular rib, and its outer diameter is larger than the diameter of the through hole 443. The limiting rib 414 abuts against the inner sidewall of the protective shell 440, so as to prevent the acidic water pipe connector 412 and the alkaline water pipe connector 413 from moving axially outward and detaching from the corresponding outlets.

[0074] The axis of the inlet 401 extends along the vertical direction of the electrolytic cell 420, and the axis of the inlet pipe connector 411 extends along the length direction of the electrolytic cell 420. The inlet pipe connector 411 is provided with a plug sleeve extending along the vertical direction of the electrolytic cell 420. Therefore, by connecting the plug sleeve with the inlet 401, the inlet pipe connector 411 can be prevented from moving radially along the inlet 401 and detaching from the inlet.

[0075] When assembling the electrolysis device 400, first connect the acid water pipe connector 412 to the acid water outlet 402, the alkaline water pipe connector 413 to the alkaline water outlet 403, and the water inlet pipe connector 411 to the water inlet 401, and then align and snap the first half shell 441 and the second half shell 442 together.

[0076] Finally, to enable a single pipe fitting to accommodate various pipe diameters, the acid water fitting 412, the alkaline water fitting 413, and the inlet water fitting 411 each have three connecting sections, with the diameter of the three connecting sections decreasing in the direction away from the electrolytic cell 420. This increases the versatility and adaptability of the pipe fittings and reduces usage costs.

[0077] It is understood that in other embodiments of this utility model, various pipe diameters can be adapted by replacing the acid water pipe joint, the alkaline water pipe joint, and the water inlet pipe joint.

[0078] In addition to the preferred embodiments described above, this utility model has other implementation methods. Those skilled in the art can make various changes and modifications based on this utility model, and all such changes and modifications, as long as they do not depart from the spirit of this utility model, should fall within the scope defined in the claims of this utility model.
