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 alkaline water outlet is connected to the water inlet of the dishwasher body through an alkaline water pipe, and 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

[0006] To achieve the above-mentioned technical objectives, the present invention provides a dishwasher water tank.

Preferably, the guide rib includes a guide section and a stop section, the stop section extending upward from the top of the guide section and inclined or curved in a direction away from the fourth flow channel.

[0009] Preferably, the upper end of the fourth flow channel is provided with a second exhaust port, which is directly connected to the breathing channel.

An anti-siphon structure is provided between the upper end of the inlet section and the upper end of the outlet section. The anti-siphon structure is provided with a first vent. A first flow meter is provided in the water inlet channel.

[0013] Preferably, the tank body further defines a soft water channel, which is located at the bottom of the tank body and extends laterally, and is situated between the lower end of the water outlet section and the first flow channel.

[0014] 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 a first flow channel, and the acidic water outlet is connected to a fourth flow channel.

[0015] By adopting the above technical solution, this utility model has the following advantages:

[0016] 1. The internal enclosure of this utility model includes a water storage chamber, a first flow channel, a third flow channel located between the water storage chamber and the washing chamber and capable of being switched on and off, a breathing channel connected to the washing chamber, and a fourth flow channel connected to the breathing channel. An alkaline water outlet is connected to the first flow channel, the first flow channel is kept in communication with the washing chamber, an acidic 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 the gas is discharged into the breathing channel through the fourth 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. 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 descale the washing chamber. Therefore, this utility model'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 respective most suitable stages. Alkaline water can be produced and used as needed, while acidic water can be stored and used when needed, thereby improving resource utilization. In addition, by integrating multiple flow channels and the storage chamber into the tank body, the need for multiple separate pipelines is eliminated, making the dishwasher more compact and the overall size smaller. Moreover, since the electrolysis device generates gas during water electrolysis... Therefore, acidic water flowing into the storage chamber through the fourth channel carries some gas into the storage chamber, causing bubbles to form and producing abnormal noise. This solution connects the fourth channel to the breathing channel, allowing gas to be expelled into the breathing channel as acidic water flows through the fourth channel, thus reducing the amount of gas entering the storage chamber, thereby reducing bubble formation and preventing abnormal noise. Finally, in dishwashers using water softeners, when it is necessary to discharge the ultra-hard water from the softener, the electrolysis device is turned off, the third channel is opened, and the ultra-hard water passes through the electrolysis device. Then it enters the fourth flow channel and flows into the washing chamber through 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, the hard water in the water storage chamber 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 to avoid the generation of bubbles in the water storage chamber and the occurrence of abnormal noise.

[0017] 2. The water storage chamber is equipped with an overflow port connected to the breathing channel. The fourth flow channel and the water storage chamber share a vertically extending common wall. The common wall has multiple first vent holes, which are connected to the breathing channel through the overflow port. With this design, after acidic water carrying gas enters the fourth flow channel, due to gravity, the acidic water flows downwards to the bottom of the water storage chamber for storage, while the gas moves upwards, entering the upper space of the water storage chamber through the first vent holes on the common wall, and then entering the breathing channel through the overflow port, finally being discharged into the washing chamber. This prevents gas from accumulating in the water storage chamber or pipes, thus ensuring stable water flow and normal system operation. Furthermore, the multiple first vent holes increase the venting area of ​​the fourth flow channel, allowing more gas in the acidic water to be discharged, improving the venting effect. Finally, if due to… If a control malfunction or calculation error occurs, the electrolysis device may continuously inject acidic water into the water storage chamber. If the third flow channel is not opened in time, the water storage chamber may become full. If it is full and acidic water continues to flow in, the tank may burst and leak into the dishwasher, causing serious malfunctions such as short circuits and structural corrosion. Therefore, an overflow port and a vent are provided to allow excess water in the water storage chamber to be safely and promptly guided into the washing chamber through the overflow port and vent, preventing 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.

[0018] 3. The common wall includes multiple vertically spaced guide ribs, with a first vent hole formed between two adjacent guide ribs. Compared to setting multiple first vent holes on the common wall, which requires a complex core-pulling structure in the mold, this solution eliminates the need for a core-pulling structure, thus simplifying mold complexity and reducing manufacturing costs.

[0019] 4. The guide ribs include a guide section and a stop section. The stop section extends upward from the top of the guide section and slopes or bends away from the fourth flow channel. This design enhances the structural strength of the guide ribs, preventing deformation, and also blocks upward splashing water flow through the stop section, guiding the water flow downward along its surface and ultimately back into the fourth flow channel. This allows gas to pass through the first vent and reduces liquid flow through the first vent, achieving more thorough gas-liquid separation. Especially in dishwashers using softened water, when it is necessary to discharge the ultra-hard water from the softener, the electrolysis device is closed, the third flow channel is open, and the ultra-hard water enters the fourth flow channel after passing through the electrolysis device, flowing into the washing chamber through the bottom of the storage chamber. As the ultra-hard water flows downward through the fourth flow channel, the stop section effectively prevents it from entering the storage chamber through the first vent, thereby reducing the contamination of the inner wall of the storage chamber by ultra-hard water and effectively preventing white water stains from appearing after the dishes are washed and dried.

[0020] 5. A second vent is provided at the upper end of the fourth flow channel, which is directly connected to the breathing channel. This design is simple in structure 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.

[0021] 6. The cabinet also includes a second flow channel, which connects with the fourth flow channel to form an inverted U-shaped flow channel. The lower end of the second flow channel connects to the acidic water outlet. This design allows the electrolysis device to be installed below the water tank. For example, the space between the inner tank and the dishwasher's bottom frame can be used to 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 make it impossible to install later.

[0022] 7. The first flow channel extends from the bottom to the top of the tank. The lower part of the tank has a first connection port to the washing chamber, and the top of the first flow channel has a first water outlet higher than the first connection port. The first water outlet is connected to the first connection port via a breather channel. The upper end of the second flow channel has a second water outlet connected to the upper end of the fourth flow channel. This design allows the inlet ends of both the first and second flow channels to be located close to the bottom of the tank, thus allowing the electrolysis device to be installed below the water tank. Furthermore, placing the first water outlet at the top of the first flow channel effectively prevents water from the washing chamber from flowing back into the first flow channel, thus preventing contamination of the first flow channel. This anti-contamination effect is even stronger 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 and elongated water channel, results in low water flow resistance, which is beneficial for water storage in the storage chamber. Additionally, the top placement of the two water outlets allows for adjustable water output ratios.

[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 cabinet also includes a soft water channel, located at the bottom and extending laterally. This channel lies between the lower end of the water outlet section and the first flow channel. This design allows for the integration of more flow channels within the cabinet, reducing the need for piping and resulting in a more compact dishwasher structure. Attached Figure Description

[0036] Example 1

[0037] Combination Figures 1 to 6 The 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 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 tank body 100 internally defines a water storage chamber 130, a first flow channel 110, a third flow channel 140 located between the water storage chamber 130 and the washing chamber and which is connectable and disconnectable, a breathing channel 150 communicating with the washing chamber, and a fourth flow channel 160 communicating with the breathing channel 150. The alkaline water outlet is connected to the first flow channel 110, and the first flow channel 110 is kept in communication with the washing chamber. The acidic water outlet is connected to the fourth flow channel 160, and the fourth flow channel 160 is connected to the bottom of the water storage chamber 130 so that acidic water flows downward into the water storage chamber 130 through the fourth flow channel 160 and exhausts gas into the breathing channel 150 through the fourth flow channel 160.

[0038] 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, for the hot rinsing stage, to achieve sterilization and disinfection of the dishes and descaling of the washing chamber. Therefore, this embodiment demonstrates… By separating alkaline and acidic water, the water tank avoids the problem of neutralization failure within the tank, allowing each type of water to exert its maximum effectiveness at its optimal stage. Alkaline water can be produced and used immediately as needed, while acidic water can be stored and utilized when required, thus improving resource utilization. Furthermore, by integrating multiple flow channels and the water storage chamber 130 into the tank body 100, the need for multiple separate piping is eliminated, making the dishwasher more compact and reducing the overall size of the machine. Moreover, since the electrolysis device generates gas during water electrolysis, acidic water flows into the water storage chamber through the fourth flow channel 160. When acidic water flows through the water reservoir 130, some gas may enter the reservoir 130, causing bubbles and abnormal noise. This solution connects the fourth flow channel 160 to the breathing channel 150, allowing gas to be expelled into the breathing channel 150 and flow into the washing chamber as the acidic water passes through the fourth flow channel 160. This reduces the amount of gas entering the reservoir 130, thus reducing bubble formation and preventing abnormal noise. Finally, in dishwashers using water softeners, when it is necessary to discharge the hard water from the softener, the electrolysis function is turned off, the third flow channel 140 is opened, and the hard water enters the fourth flow channel after passing through the electrolysis device. The fourth flow channel 160 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.

[0039] In this embodiment, the box 100 is formed by sealing two half-shells together by hot-melt welding. Multiple partition ribs are formed inside the box 100, dividing the interior into multiple spaces. These multiple spaces include at least the aforementioned first flow channel 110, water storage chamber 130, third flow channel 140, and fourth flow channel 160. Figure 2 This shows a schematic diagram of the internal structure of one of the half-shells.

[0040] Preferably, in this embodiment, the water storage cavity 130 is provided with an overflow port 131 that communicates with the breathing channel 150. The fourth flow channel 160 and the water storage cavity 130 have a vertically extending common wall. The common wall is provided with a plurality of first exhaust holes 161. The first exhaust holes 161 communicate with the breathing channel 150 through the overflow port 131, thereby realizing the communication between the fourth flow channel 160 and the breathing channel 150. With this design, after the acidic water carrying gas enters the fourth flow channel 160, due to gravity, the acidic water flows downwards to the bottom of the storage chamber 130 for storage, while the gas moves upwards, entering the upper space of the storage chamber 130 through the first exhaust port 161 on the common wall, and then entering the breathing channel 150 through the overflow port 131, and finally being discharged into the washing chamber. This avoids the accumulation of gas in the storage chamber 130 or pipes, thereby ensuring stable water flow and normal system operation. In addition, multiple first exhaust ports 161 can increase the exhaust area of ​​the fourth flow channel 160, so that more gas in the acidic water can be discharged, improving the exhaust effect. Finally, if Due to control malfunction or calculation error, the electrolysis device continuously injects acidic water into the water storage chamber 130. If the third flow channel 140 is not opened in time, the water storage chamber 130 may become full. If it is full, the continuous flow of acidic water will cause the tank to burst and leak into the dishwasher body, causing serious malfunctions such as short circuits and structural corrosion. Therefore, an overflow port 131 and a breathing channel 150 are provided so that excess water in the water storage chamber 130 can be safely and timely 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.

[0041] 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.

[0042] 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.

[0043] 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 enhances the structural strength of the guide rib 162, preventing deformation, and also blocks upward splashing water flow through the stop section 1622, guiding the water flow downward 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 softeners, when it is necessary to discharge the ultra-hard water from the water softener, the electrolysis device 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, 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 thus preventing the ultra-hard water from entering the washing chamber and causing white water stains on the dishes after drying.

[0044] 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.

[0045] Furthermore, the housing of this embodiment also defines a second flow channel 120, that is, a second flow channel 120 is included in multiple spaces. The second flow channel 120 extends from the bottom of the housing 100 toward the top of the housing 100. The second flow channel 120 is located on the side of the fourth flow channel 160 away from the water storage chamber 130. The second flow channel 120 and the fourth flow channel 160 are connected to form an inverted U-shaped flow channel. The lower end of the second flow channel 120 is connected to the acidic water outlet. The upper end of the second flow channel 120 is provided with a second water outlet 121 that is connected to the upper end of the fourth flow channel 160. The lower part of the housing 100 facing the inner liner is provided with a first communication port 101 that is connected to the washing chamber. The first flow channel 110 extends from the bottom of the housing 100 toward the top of the housing 100. The top of the first flow channel 110 is provided with a first water outlet 111. The first water outlet 111 is connected to the first communication port 101 through the breathing channel 150. This design allows the 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, by utilizing the space between the inner tank and the bottom frame of the dishwasher. This avoids the problem of the electrolysis device being mounted on the side of the water tank, which would increase the overall lateral size of the dishwasher and make it impossible to install later. In addition, it ensures that alkaline water can flow smoothly from the high-positioned first outlet 111 into the low-positioned first connecting 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 outlet 111, effectively maintaining the anti-fouling characteristics of the first flow channel 110. The anti-fouling effect is even better when the first outlet 111 is close to the top of the cabinet. The second outlet 121 is located at the top of the second flow channel 120. Since the second flow channel 120 is usually a narrow and long water channel, the water flow resistance is small, which is conducive to water storage in the water storage chamber 130. Furthermore, the top-positioning of the two outlets creates conditions for adjusting the water output ratio of the two outlets.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] Preferably, the water tank also includes a first control valve 200 installed on the tank body 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 200 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. 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, while the third flow channel 140 is disconnected. The electrolysis device starts to produce alkaline 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 is opened to allow acidic water in the water storage chamber 130 to enter the washing chamber. Similarly, when it is necessary to discharge ultra-hard water, the first control valve 200 and the electrolysis device are closed. At the same time, the third flow channel 140 is opened to allow ultra-hard water to enter the bottom of the water storage chamber 130 and flow into the washing chamber through the electrolysis device, the second flow channel 120, and the fourth flow channel 160. Thus, by setting the first control valve 200 and controlling its opening and closing with the third flow channel 140, different types of water can be allowed to enter the washing chamber as needed.

[0050] 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.

[0051] 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 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 drainage section 151 is located between the first flow channel 110 and the water storage cavity 130. Its vertical extension means that it extends 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 drainage section 151 is bent. The lower end of the drainage section 151 is connected to the first connecting port 101, and the upper end of the drainage section 151 is connected to the first connecting port 101. The first outlet 111 is connected to one end of the guide section 152, and the other end of the guide section 152 extends obliquely upward and connects to the overflow port 131. This allows the water storage chamber 130 to connect to the washing chamber through the breathing channel 150 (equivalent to the breathing channel 150 connecting to the atmosphere). In addition, it also ensures that both normal alkaline water and overflowing acidic water eventually enter the washing chamber through the same first connecting 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. Finally, the other end of the guide section 152 extends obliquely upward and connects to the overflow port 131, so that the water discharged through the overflow port 131 can quickly flow to the diversion section 151 under the action of gravity within the guide section 152, and effectively prevent the water in the guide section 152 from flowing back into the water storage chamber 130.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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 5 As 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 inlet channel 170 stops, a negative pressure will form upstream of the inlet channel, causing the water stagnant downstream to tend to flow back due to siphoning. Because the first vent 170a is connected to the atmosphere, air from the atmosphere can enter the 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.

[0056] 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 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 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 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.

[0057] 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.

[0058] It is understood that in other embodiments of this utility model, the electrolysis device is mounted on the water tank, and the acidic outlet is directly connected to the upper end of the fourth flow channel, thereby eliminating the need for the second flow channel.

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. 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.
