Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to dishwasher water tank and dishwasher. 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 require a drinking water pipe to store and utilize acidic water. When the dishwasher is not used in conjunction with the drinking water pipe, the acidic water is usually discharged into the sewer, resulting in waste. In addition, since the acidic water outlet is connected to the water tank through an acidic water pipe, and the water tank is connected to the wastewater pipe through a pipeline, it can be seen that the existing solution requires a lot of pipelines, which is inconvenient for layout and connection, especially for built-in dishwashers, and is not conducive to later assembly. Utility Model Content

[0014] Preferably, the water tank further includes a second control valve installed on the tank body, the tank body is also provided with a second communication port communicating with the washing chamber, the third flow channel is connected to the second communication port, and the second control valve is used to control the opening and closing of the third flow channel.

[0015] This utility model also discloses a dishwasher, including a water tank, an inner tank with a washing chamber, and an electrolysis device for electrolyzing water to obtain acidic water and alkaline water. The electrolysis device includes a water inlet, an acidic water outlet, and an alkaline water outlet. The water inlet is connected to a water source. The water tank adopts the water tank described in any of the above technical solutions. The alkaline water outlet is connected to the washing chamber, and the acidic water outlet is connected to a second flow channel.

[0016] By adopting the above technical solution, this utility model has the following advantages: 1. The box of this utility model has a second flow channel and a water storage cavity connected to the second flow channel. A third flow channel that can be switched on and off is connected between the water storage cavity and the washing cavity. The alkaline water outlet is connected to the washing cavity, and the acidic water outlet is connected to the second flow channel so that the acidic water flows into the water storage cavity through the second flow channel. During the dishwasher's washing process, alkaline water can be used to rinse the dishes in the washing chamber. Because alkaline water has excellent oil and dirt removal capabilities, it effectively improves the cleaning effect on the dishes. Furthermore, when acidic water is not needed, the third flow channel can be disconnected to temporarily store acidic water in the storage chamber. When the program requires it, the third flow channel can be connected to allow the acidic water in the storage chamber to flow into the washing chamber, for example, during the hot rinsing stage, to sterilize and disinfect the dishes and remove scale from the washing chamber. Thus, this invention's water tank, by separating alkaline and acidic water, avoids the problem of neutralization failure within the tank, allowing both types of water to exert their maximum effectiveness at their most suitable stages. Alkaline water can be produced and used immediately as needed, while acidic water can be stored and utilized when needed, thereby improving resource utilization. Finally, by integrating the second flow channel, third flow channel, and storage chamber all onto the tank body, the need for multiple separate pipelines is eliminated, making the dishwasher more compact and the overall size smaller.

[0017] 2. The interior of the cabinet also defines a first flow channel. The alkaline water outlet connects to the washing chamber through the first flow channel. Both the first and second flow channels extend from the bottom to the top of the cabinet. The top of the first flow channel has a first water outlet, and the top of the second flow channel has a second water outlet. This design, by integrating the first flow channel into the cabinet, eliminates the need for separate piping, making the dishwasher more compact and smaller in overall size. Furthermore, the water inlets of the first and second flow channels can be positioned near the bottom of the cabinet, allowing the electrolysis device to be installed below the water tank. For example, the space between the inner tub and the dishwasher frame can accommodate the electrolysis device, avoiding the problem of mounting the electrolysis device on the side of the water tank, which would increase the overall lateral size of the dishwasher and prevent future installation. Additionally, if the first water outlet is located at the bottom of the first flow channel, it would be close to the bottom of the cabinet, making it easier for water in the washing chamber to flow back into the first flow channel and contaminate it. If the second water outlet is located at... The bottom of the second flow channel is close to the bottom of the tank. As the water volume and pressure in the water storage chamber increase, the difficulty of water storage will increase, causing fluctuations in the water output ratio of the first and second water outlets, which in turn affects the pH value of the electrolyzed water. Therefore, placing the first water 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, thereby preventing the first flow channel from being contaminated. The anti-fouling effect is even better when the first water outlet is close to the top of the tank. Placing the second water outlet at the top of the second flow channel, since the second flow channel is a narrow water channel, has low water flow resistance, which is conducive to water storage in the water storage chamber. In addition, the top placement of the two water outlets creates conditions for the adjustable water output ratio of the two water outlets.

[0018] 3. The tank also includes a drainage channel. The lower part of the tank has a first connection port to the washing chamber, and the first water outlet is positioned higher than this connection port. The first water outlet connects to the first connection port via the drainage channel. This design ensures that alkaline water flows smoothly from the higher first water outlet into the lower first connection port and then into the washing chamber. Simultaneously, water in the washing chamber cannot flow backwards beyond the height of the first water outlet, effectively maintaining the anti-contamination characteristics of the first flow channel.

[0019] 4. The tank also includes a drainage channel. The lower part of the tank has a first connection port to the washing chamber, and the water storage chamber has an overflow port connected to the drainage channel. This allows water discharged from the overflow port to flow into the washing chamber through the drainage channel and the first connection port. With this design, if the electrolysis device continuously injects acidic water into the water storage chamber due to control malfunction or calculation error, and the third flow channel fails to open in time, the water storage chamber may become full. If full, the continuous flow of acidic water could cause the tank to burst and leak into the dishwasher, causing serious malfunctions such as short circuits and structural corrosion. Therefore, the overflow port and drainage channel ensure that excess water in the water storage chamber is safely and promptly guided into the washing chamber, preventing the tank from bursting. Simultaneously, the acidic water flowing into the washing chamber can descale, sterilize, and disinfect the washing chamber, achieving waste utilization.

[0020] 5. The overflow port is located at the top of the water storage chamber, and the second outlet is connected to the overflow port so that the water discharged from the second outlet enters the water storage chamber through the overflow port. This design allows acidic water to flow directly into the water storage chamber after exiting the second outlet, thus eliminating the need for an additional flow channel connecting the second outlet and the water storage chamber inside the tank. This simplifies the internal structure of the tank and facilitates the injection molding process of the tank.

[0021] 6. The water storage chamber is located between the first flow channel and the second flow channel. The overflow port is located at the top of the water storage chamber near the second flow channel. The first outlet is located above the top of the water storage chamber near the first flow channel. The diversion channel includes a vertically extending diversion section and a horizontally extending guide section located above the water storage chamber. The lower end of the diversion section is connected to the first connecting port. The upper end of the diversion section is connected to the first outlet and one end of the guide section. The other end of the guide section extends obliquely upward and is connected to the overflow port. This design, since the existing first connecting port is located in the lower middle part of one side of the tank, allows the water storage chamber to be located between the first and second flow channels. This allows the first flow channel to be located on the side of the water storage chamber closer to the first connecting port without changing the existing first connecting port, while the second flow channel is located on the other side of the water storage chamber away from the first connecting port. This avoids the problem of one flow channel having a longer path and the problem of water mixing between the two channels if the first and second flow channels are distributed on the same side of the water storage chamber. The design of the drainage channel ensures that both normal alkaline water and overflowing acidic water ultimately enter the washing chamber through the same first connecting port, 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. Finally, the other end of the guide section extends obliquely upward and connects to the overflow port. This allows the water discharged through the overflow port to flow quickly to the drainage section under the action of gravity within the guide section, effectively preventing water in the guide section from flowing back into the water storage chamber.

[0022] 7. The water tank also includes a first control valve installed on the tank body. The first control valve is used to control the opening and closing of the first flow channel, and a second flow meter is installed in the first flow channel. When only alkaline water is needed to enter the washing chamber, the first control valve opens, the third flow channel is closed, the electrolysis device starts to produce alkaline water and acidic water. The alkaline water enters the first flow channel and flows through the second flow meter before flowing into the washing chamber. The second flow meter monitors the water volume in real time. After reaching the preset value, it notifies the control system to shut down the electrolysis device and the first control valve. When acidic water is needed to enter the washing chamber, the first control valve is closed to prevent alkaline water from entering the washing chamber. At the same time, the third flow channel opens, allowing acidic water in the water storage chamber to enter the washing chamber. Thus, by setting the first control valve and controlling its opening and closing with the third flow channel, the two types of functional water can be allowed to enter the washing chamber as needed.

[0023] 8. The tank also includes a water inlet channel, comprising an inlet section extending from the bottom to the top of the tank and an outlet section. An anti-siphon structure is installed between the upper ends of the inlet and outlet sections, with a first vent. A first flow meter is installed within the water inlet channel. This design ensures that when water supply to the inlet channel stops, a negative pressure is created upstream, causing water stagnant downstream to tend to flow back due to siphoning. Since the first vent is open to the atmosphere, air can enter the water inlet channel to balance the pressure difference, preventing siphoning and thus avoiding non-potable water flowing back into the channel and contaminating the water source connected to the inlet end. Furthermore, the first flow meter directly and accurately measures the total water volume, allowing control of the amount of alkaline water entering the washing chamber based on the total water volume and electrolysis ratio.

[0024] 9. The water tank also includes a second control valve installed on the tank body. The tank body also has a second connection port that communicates with the washing chamber. The third flow channel is connected to the second connection port. The second control valve is used to control the opening and closing of the third flow channel. With this design, the opening and closing of the third flow channel can be controlled by opening and closing the second control valve, and the structure is simple. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. 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

[0027] Combination Figures 1 to 6The dishwasher provided in this embodiment includes a water tank, an inner tub with a washing chamber, and an electrolysis device for electrolyzing water to obtain acidic water and alkaline water. The electrolysis device includes a water inlet, an acidic water outlet, and an alkaline water outlet. The water inlet is connected to a water source. The water tank includes a tank body 100. The alkaline water outlet is connected to the washing chamber. The tank body 100 internally defines a second flow channel 120 and a water storage chamber 130 connected to the second flow channel 120. A third flow channel 140 that can be switched on and off is connected between the water storage chamber 130 and the washing chamber. The acidic water outlet is connected to the second flow channel 120 so that acidic water flows into the water storage chamber 130 through the second flow channel 120.

[0028] With the water tank in this embodiment, alkaline water can be used to rinse the dishes in the washing chamber during the dishwasher's washing process. Since alkaline water has excellent oil and dirt removal capabilities, it effectively improves the cleaning effect on the dishes. Furthermore, when acidic water is not needed, the third flow channel 140 can be disconnected to temporarily store acidic water in the water storage chamber 130. When the program requires it, the third flow channel 140 can be connected to allow the acidic water in the water storage chamber 130 to flow into the washing chamber, for example, during the hot rinsing stage, to achieve sterilization and disinfection of the dishes and cleaning of the washing chamber. Scale, etc., it can be seen that the water tank in this embodiment separates alkaline water and acidic water, avoiding the problem of neutralization failure inside the tank. It allows the two types of functional water to exert their maximum effect at their most suitable stage. Alkaline water can be produced and used as needed, while acidic water can be stored and used when needed, thereby improving resource utilization. Finally, by integrating the second flow channel 120, the third flow channel 140 and the water storage chamber 130 into the tank 100, the setting of multiple separate pipes can be eliminated, making the dishwasher more compact and the overall size smaller.

[0029] In this embodiment, the box 100 is formed by sealing two half-shells together through hot-melt welding. The box 100 has multiple partition ribs inside, which divide the interior of the box 100 into multiple spaces. Each of these multiple spaces includes at least the aforementioned second flow channel 120, water storage chamber 130, and third flow channel 140. Figure 2 This shows a schematic diagram of the internal structure of one of the half-shells.

[0030] In this embodiment, the cabinet 100 is further defined with a first flow channel 110. The alkaline water outlet is connected to the washing chamber through the first flow channel 110. With this design, by integrating the first flow channel 110 into the cabinet 100, the separate pipeline can be eliminated, making the dishwasher more compact and the overall size smaller. The first flow channel 110 and the second flow channel 120 both extend from the bottom of the cabinet 100 toward the top of the cabinet 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 positioned close to the bottom of the cabinet 100. This allows the electrolysis device to be installed below the water tank, for example, utilizing the space between the inner tub and the dishwasher frame. This avoids the problem of the electrolysis device being mounted 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 111 is located at the bottom of the first flow channel 110, it would be close to the bottom of the cabinet, making it easy for water in the washing chamber to flow back into the first flow channel 110 and contaminate it. Similarly, if the second water outlet 121 is located at the bottom of the second flow channel 120, it would be close to the bottom of the cabinet, preventing water from flowing back into the water storage chamber 130 as the water volume increases. Increased pressure leads to increased difficulty in water storage, causing fluctuations in the water output ratio of the first outlet 111 and the second outlet 121, which in turn affects 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 tank. Placing the second outlet 121 at the top of the second flow channel 120 is beneficial because the second flow channel 120 is usually a narrow and long water channel with low water flow resistance, which is conducive to water storage in the water storage chamber 130. Furthermore, placing the two outlets at the top creates conditions for adjustable water output ratio between the two outlets.

[0031] Preferably, in this embodiment, both the first flow channel 110 and the second flow channel 120 extend from the bottom of the housing 100 to the top of the housing 100. This allows the first water outlet 111 and the second water outlet 121 to be positioned upwards. The upward positioning of the first water 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 water outlet 121 facilitates water storage in the water storage chamber 130. In this embodiment, the heights of the first water outlet 111 and the second water outlet 121 are the same. At this time, the ratio of alkaline water discharged through the first water outlet 111 to acidic water discharged through the second water outlet 121 is a fixed value, thereby making the amount of alkaline water produced moderate, which in turn makes the alkaline water preparation time moderate, the pH value of the electrolyzed water moderate, and the service life of the electrolysis device moderate, suitable for removing general pollution.

[0032] 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.

[0033] 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, reducing the pH value of the electrolyzed water, and increasing the service life of the electrolysis device. However, the cleaning effect is reduced, making it suitable for removing light pollution.

[0034] Preferably, the water tank also includes a first control valve 200 installed on the tank body 100. The first control valve 200 is used to control the opening and closing of the first flow channel 110, that is, 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 200 is located at the connection 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, that is, to control the opening and closing of the first flow channel 110. A second flow meter 300 is also provided in the first flow channel 110. Preferably, the second flow meter 300 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 200 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 starts to produce alkaline water and acidic water. The alkaline water enters the first flow section 112, passes through the opened first control valve 200, enters the second flow section 113, and finally flows into the washing chamber. The second flow meter 300 monitors the water volume in real time. After reaching the preset value, it notifies the control system to shut down the electrolysis device and the first control valve 200, 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 200 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 200 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.

[0035] Furthermore, in this embodiment, the housing 100 also includes a drainage channel 150, meaning that one drainage channel 150 is included among multiple spaces. The lower part of the housing 100 facing the inner liner has a first communication port 101 connecting to the washing chamber. The first water outlet 111 is positioned higher than the first communication port 101, and the first water outlet 111 is connected to the first communication port 101 through the drainage channel 150. This design ensures that alkaline water can smoothly flow 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.

[0036] In this embodiment, the water storage chamber 130 is equipped with an overflow port 131, which is connected to the drainage channel 150 so that water discharged from the overflow port 131 flows into the washing chamber through the drainage channel 150 and the first connecting port 101. With this design, if the electrolysis device continuously injects acidic water into the water storage chamber 130 due to control failure or calculation error, and the third flow channel 140 is not opened in time, the water storage chamber 130 may become full. If it is full and acidic water continues to flow in, the tank will burst and leak into the dishwasher body, causing serious malfunctions such as short circuits and structural corrosion. Therefore, by connecting the overflow port 131 and the drainage channel 150, excess water in the water storage chamber 130 can be safely and promptly guided into the washing chamber through the overflow port 131 and the drainage channel 150 to prevent the water tank from bursting. Simultaneously, the acidic water flowing into the washing chamber can also descale, sterilize, and disinfect the washing chamber, enabling reuse.

[0037] 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.

[0038] Preferably, the water storage chamber 130 is located between the first flow channel 110 and the second flow channel 120, such as... Figure 2As shown, the first flow channel 110 is located on the left side of the water storage cavity 130, and the second flow channel 120 is located on the right side of the water storage cavity 130. Since the existing first connecting port 101 is located in the lower middle part of the left side of the box 100, the water storage cavity 130 is located between the first flow channel 110 and the second flow channel 120. This allows the first flow channel 110 to be located on the side of the water storage cavity 130 close to the first connecting port 101 without changing the existing first connecting port, while the second flow channel 120 is located on the other side of the water storage cavity 130 away from the first connecting port 101. This effectively shortens the path of the first flow channel 110 and the second flow channel 120, and the layout is more reasonable. If the first flow channel 110 and the second flow channel 120 are distributed on the same side of the water storage cavity 130, it will lead to the problem that one of the flow channels has a longer path, the two water channels are prone to cross-contamination, and the layout is not good.

[0039] like Figure 2 and 3 As 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 drainage channel 150 includes a vertically extending drainage section 151 and a horizontally extending guide section 151 located above the water storage cavity 130. 52. The diversion section 151 is located between the first flow channel 110 and the water storage chamber 130. Its vertical extension refers to the extension from the top of the box to the bottom of the box. It can bend or extend in a straight line. In this embodiment, the diversion section 151 extends in a bend. The lower end of the diversion section 151 is connected to the first connecting port 101. The upper end of the diversion section 151 is connected to the first water 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 ensures that both normal alkaline water and overflowing acidic water ultimately enter the washing chamber through the same first connection port 101, eliminating the need for separate flow channels for the two water paths and greatly simplifying the interface design between the water tank and the washing chamber. Finally, the other end of the guide section 152 extends obliquely upward and connects to the overflow port 131, allowing the water discharged through the overflow port 131 to flow quickly to the guide section 151 under gravity within the guide section 152, effectively preventing water in the guide section 152 from flowing back into the water storage chamber 130.

[0040] 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.

[0041] 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.

[0042] Furthermore, in this embodiment, the right side wall of the water storage chamber is spaced apart from the second flow channel 120, so that a fourth flow channel 160 is formed between the right side wall of the water storage chamber and the second flow channel 120. The fourth flow channel 160 is arranged parallel to the second flow channel 120 and extends downward from the top of the box to the bottom of the water storage chamber 130. The fourth flow channel 160 and the second flow channel 120 are connected to form an inverted U-shaped channel, that is, the upper end of the fourth flow channel 160 is connected to the second outlet 121 of the second flow channel 120, and the lower end of the fourth flow channel 160 is connected to the bottom of the water storage chamber 130, so that acidic water flows into the water storage chamber 130 sequentially through the second flow channel 120 and the fourth flow channel 160.

[0043] Because the electrolysis device generates gas during water electrolysis, acidic water flowing into the water storage chamber 130 through the second flow channel 120 and the fourth flow channel 160 will carry some gas into the water storage chamber 130, causing bubbles to form in the water storage chamber 130 and producing abnormal noise. In order to reduce the generation of bubbles, the fourth flow channel 160 in this embodiment is connected to the drainage channel 150. Since the drainage channel 150 is connected to the washing chamber through the first connecting port 101, it is equivalent to the drainage channel 150 being connected to the atmosphere. The fourth flow channel 160 is connected to the drainage channel 150, thereby enabling the fourth flow channel 160 to be connected to the atmosphere. In this way, when acidic water flows downward into the water storage chamber 130 through the fourth flow channel 160, the gas in the acidic water can be discharged into the washing chamber through the drainage channel 150.

[0044] Specifically, the fourth flow channel 160 and the water storage chamber 130 share a vertically extending common wall. The common wall is provided with multiple first vent holes 161, which are connected to the drainage channel 150 through the overflow port 131, thereby enabling the fourth flow channel 160 to communicate with the atmosphere. The common wall includes multiple vertically spaced guide ribs 162, with the first vent holes 161 formed between two adjacent guide ribs 162. This facilitates the processing and forming of the first vent holes 161, thereby reducing the processing difficulty of the housing 100.

[0045] Preferably, 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. With this design, when the inlet of the electrolysis device is connected to the outlet of the water softener, and the inlet of the water softener is connected to a water source, and it is necessary to discharge the ultra-hard water from the water softener, the first control valve 200 closes, the third flow channel 140 opens, and the electrolysis device closes. At this time, the ultra-hard water passes through the electrolysis device and enters the second flow channel 120, then flows through the fourth flow channel 160 into the bottom of the water storage chamber 130 and into the washing chamber. 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 through the first vent hole 161. The water storage chamber 130 is designed to reduce the amount of hard water remaining in it. This is because when tap water is subsequently introduced into 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, it will enter the washing chamber along 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 first vent 161, the overflow port 131, and the drainage channel 150, preventing the formation of bubbles in the water storage chamber 130 and causing abnormal noises.

[0046] It is understood that in other embodiments of this utility model, the common wall is a continuously arranged structure, without a first exhaust hole, while the upper end of the fourth flow channel is provided with a second exhaust hole, which is directly connected to the right end of the drainage channel. This allows the gas in the fourth flow channel to be discharged into the washing chamber through the second exhaust hole and the drainage channel.

[0047] Furthermore, in this embodiment, the wall of the tank 100 facing the inner liner is also provided with a second connecting port 102. 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 water tank also includes a second control valve 400 installed on the tank 100. The second control valve 400 is used to control the opening and closing of the third flow channel 140, that is, the second control valve 400 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 400, which is a simple structure.

[0048] In addition, the housing 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 chamber 130, and includes an inlet section 171 extending from the bottom of the housing to the top of the housing 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, and is located above the water storage chamber 130. The portion of the inlet section 171 is spaced apart from the upwardly arched portion of the top wall of the water storage chamber 130, thus defining 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 5As shown in the diagram, the first vent 170a connects the drainage channel 150 and the inner arc-shaped flow channel. Since the drainage 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 form upstream of the water inlet channel, causing the water stagnant downstream of the water inlet channel to tend to flow back due to siphon. Because the first vent 170a is connected to the atmosphere, air from the atmosphere can enter the water inlet channel 170 through the first vent 170a to balance the flow. The pressure difference within the water channel 170 prevents siphoning in the water inlet channel 170, thereby avoiding non-potable water from 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, the water inlet channel 170 is equipped with a first flow meter 500. The design of the first flow meter 500 can directly and accurately measure the total water volume, and the amount of alkaline water entering the washing chamber can be controlled according to the total water volume and the electrolysis ratio.

[0049] In this embodiment, the interior of the housing 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 housing 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 housing. 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 is provided with a drain vent 183, which is connected to the drainage 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 box 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 drainage 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.

[0050] The soft water channel 190 is located at the bottom of the tank 100 and extends laterally. The soft water channel 190 is located between the lower end of the water outlet section 172 and the first flow channel 110.

[0051] It is understood that in other embodiments of this utility model, the second outlet and the overflow outlet in this embodiment can also 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 an additional flow channel connecting the second outlet and the water storage chamber within the tank, thereby simplifying the internal structure of the tank and facilitating injection molding.

[0052] It is understood that in other embodiments of this utility model, the alkaline water outlet can also be connected to the washing chamber through a separately provided alkaline pipe, which is independent of the water tank; or the alkaline water outlet can be directly connected to the washing chamber, so as to eliminate the need for an alkaline pipe or a first flow channel. Example 2

[0053] like Figure 7 and Figure 8 As shown, this embodiment also discloses a dishwasher, which includes a water tank, an inner tank 600 with a washing chamber, a bottom frame 700, a water softener 800, and an electrolysis device 900 for electrolyzing water to obtain acidic water and alkaline water. The water tank is the water tank described in Embodiment 1. The electrolysis device 900 is installed on the bottom frame 700 and located below the inner tank 600. The electrolysis device 900 includes a water inlet, an acidic water outlet, and an alkaline water outlet. The water inlet is connected to a water source through the water softener 800. Specifically, the lower end of the water inlet section 171 is connected to the water source, the lower end of the water outlet section 172 is connected to the water inlet of the water softener 800, the water outlet of the water softener 800 is connected to the water inlet of the soft water channel 190, the water outlet of the soft water channel 190 is connected to the water inlet of the electrolysis device 900, and the alkaline water outlet is connected to the lower end of the first flow channel 110, and the acidic water outlet is connected to the lower end of the second flow channel 120.
