[0051] And a water path commutation structure, which is adapted to open or close the breathing water path and the electrolysis water path so that the breathing water path and the electrolysis water path flow alternately.

[0052] The dishwasher provided by the present invention further includes:

[0053] A water cup, which is arranged in the inner container, and a disinfectant discharge port is arranged on the water tank, and the disinfectant discharge port is communicated with the water cup through an electromagnetic valve.

[0054] For the dishwasher provided by the present invention, the plane where the disinfectant discharge port is located is higher than the upper surface of the water cup.

[0055] The technical solution of the present invention has the following advantages:

[0056] 1. The dishwasher provided by the present invention includes: a chamber structure with a water tank chamber disposed inside; a brine generating device connected to the water tank chamber and adapted to introduce brine into the water tank chamber; an electrolysis assembly disposed inside the water tank chamber and adapted to perform electrolysis on the brine generated by the brine generating device; a cabinet, on which the chamber structure acts, the cabinet including an inner container and a door body adapted to enclose the inner container, the inner container being adapted to place tableware to be cleaned, and the chamber structure being adapted to act on at least one of the inner container and the door body; substances located in the chamber structure being adapted to flow out of the water tank chamber and into the inner container.

[0057] Brine for electrolysis is generated by the brine generating device. The chamber structure itself is used to hold the brine generated by the brine generating device. The brine can be electrolyzed in the chamber structure to form hypochlorite ions with high valence. The disinfectant with high oxidizing property will enter the inner container and perform cleaning operations on the tableware, the bowl basket, the side walls, etc. in the inner container, and the fruits and vegetables in the inner container, thereby realizing a comprehensive disinfection operation on the inner container.

[0058] 2. In the dishwasher provided by the present invention, when the water volume inside the water tank is excessive, the excess water can be drained from the water tank through the overflow port. In addition, the highly oxidizing disinfectant generated in the water tank is clean water, while the water in the inner container is turbid water mixed with a large amount of oil stains. At this time, it is necessary to prevent the water in the inner container from flowing back into the water tank and polluting the water in the water tank. By setting an overflow and exhaust structure, a one-way flow of the clean water in the water tank into the inner container can be achieved. At the same time, when an electrolysis reaction occurs inside the water tank through the overflow and exhaust structure, flammable gases such as hydrogen will be generated inside. By setting the overflow port, the hydrogen can be quickly led out of the water tank to the outside, ensuring the safety of the water tank itself.

[0059] 3. The overflow and exhaust structure of the dishwasher provided by the present invention includes: a water and gas inlet penetrating through the first side of the overflow and exhaust structure; a water blocking end cover disposed on the second side of the overflow and exhaust structure and arranged along the extending direction of the water and gas inlet, adapted to block the extending direction of the water and gas inlet. By setting the water blocking end cover, a one-way flow of the clean water in the water tank into the inner container can be achieved.

[0060] 4. The dishwasher provided by the present invention, the anti-backflow rib is arranged in the overflow port of the water tank, specifically arranged on the conduction path between the overflow port and the overflow exhaust port, and preferably arranged at a position in the overflow port corresponding to the overflow exhaust port. Thus, the liquid or gas at a specific angle from the second side of the overflow exhaust structure not only has to be blocked by the water-blocking end cover, but also has to be blocked by the anti-backflow rib again after a small amount of liquid or gas enters the overflow exhaust port, reducing the situation of entering the overflow exhaust structure due to splashing.

[0061] The cooperation between the anti-backflow rib and the water-blocking end cover makes the diversion channel inside the overflow exhaust structure form a meandering structure, increasing the blockage of the liquid or gas at a specific angle from the second side of the overflow exhaust structure, and increasing the difficulty of the liquid or gas at a specific angle from the second side of the overflow exhaust structure entering the overflow exhaust structure.

[0062] 5. The water tank provided in this embodiment, the lowest point position of the anti-backflow rib in the vertical direction is higher than the lowest point position of the overflow exhaust port. Thus, after the water overflowing in the water tank enters the water and gas inlet, it will be blocked by the anti-backflow rib to avoid backflow; and when the external water enters from the overflow exhaust port and flows towards the water tank, it will also be blocked by the anti-backflow rib, thereby reducing the probability of external water entering the water tank.

[0063] 6. The dishwasher provided by the present invention, by setting the opening direction of the overflow exhaust port at an angle with the spraying direction of the spray arm, the specific value range is 90°≤β2≤180°, that is, the opening direction of the overflow exhaust port is set in a direction approximately opposite to the spraying direction of the spray arm, which can reduce the spray water flow of the spray arm from entering the overflow exhaust structure, and further reduce the spray water flow of the spray arm from entering the water tank.

[0064] 7. The dishwasher provided by the present invention, the drain port is arranged at the top position of the water tank chamber and extends towards the inside of the water tank chamber. Through the above setting method, it can effectively prevent the disinfectant prepared inside the water tank from overflowing to the outside through the water channel during the water injection of the water tank and causing pollution to the outside.

[0065] By arranging the drain port at the top position of the water tank chamber, when the water tank is storing water, the brine introduced into the water tank will not flow out from the drain port located around the middle of the water tank.

[0066] 8. The dishwasher provided by the present invention, the chamber structure further includes: a respirator, and the water tank is arranged inside the respirator; the respirator includes: a water inlet and the water outlet, and the electrolysis component is communicated with the water inlet and the water outlet; a breathing water path and an electrolysis water path separated from the breathing water path are arranged inside the electrolysis component, and the electrolysis component is arranged on the electrolysis water path; and a water path commutation structure, which is adapted to open or close the breathing water path and the electrolysis water path so that the breathing water path and the electrolysis water path circulate alternately.

[0067] An electrolysis component is arranged inside the traditional respirator, and the electrolysis component realizes the preparation of disinfectant inside the respirator by adopting the method of electrolyzing brine. The prepared disinfectant can enter the inside of the dishwasher to realize the comprehensive disinfection and sterilization of the dishwasher. Moreover, further, under the action of the water path commutation structure, the respirator can execute different functions according to the requirements of the dishwasher. When the dishwasher needs to be disinfected, the electrolysis water path is opened, and in other states, the breathing water path is used.

[0068] Through the above setting method, the preparation of the disinfectant itself can be realized through the respirator, which helps to reduce the structure involved in the whole machine and improve the compactness of the whole machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] Embodiment 1

[0092] This embodiment provides a dishwasher, including:

[0093] A chamber structure with a water tank chamber provided inside;

[0094] In this embodiment, the chamber structure itself is not overly limited: as an implementation manner, the chamber structure itself can adopt a water tank; as another implementation manner, the chamber structure itself adopts an integrated structure of a breather and a water tank;

[0095] A brine generating device, connected to the water tank chamber, adapted to introduce brine into the water tank chamber;

[0096] Correspondingly, when the chamber structure itself is a water tank, the brine generated by the brine generating device will enter the water tank; when the chamber structure adopts an integrated structure of a breather and a water tank, the brine generated by the brine generating device will enter the water tank inside the breather;

[0097] An electrolysis assembly 17 is disposed inside the water tank chamber and is adapted to perform electrolysis on the brine generated by the brine generating device;

[0098] The structure of the electrolysis assembly 17 itself is not limited, as long as it can achieve the electrolysis operation of the brine itself. At the same time, the installation method of the electrolysis assembly 17 in the water tank or the respirator is not overly limited, as long as stable installation can be achieved;

[0099] A box body, on which the chamber structure acts. The box body includes an inner container 1 and a door body adapted to enclose the inner container 1. The inner container 1 is adapted to place tableware 2 to be cleaned, and the chamber structure is adapted to act on at least one of the inner container 1 and the door body;

[0100] Specifically, as an implementation manner, the water tank can be directly disposed on the inner container 1, or the water tank is disposed on the door body; as other implementation manners, the respirator is disposed on the inner container 1, or the respirator is disposed on the door body. In this embodiment, regardless of which setting method is adopted, a water path connecting the box body and the chamber structure needs to be set;

[0101] The substance located in the chamber structure is adapted to flow out of the water tank chamber and enter the inner container 1.

[0102] Brine for electrolysis is generated by the brine generating device. The brine can achieve electrolysis of itself in the water tank and form highly-valent hypochlorite ions. The highly-oxidizing brine will enter the inner container 1 through the overflow port 233 and the through hole 101, and perform cleaning operations on the tableware 2 in the inner container 1, the bowl basket in the inner container 1, the side walls, etc., and the fruits and vegetables in the inner container 1, so as to achieve a full-range disinfection operation on the inner container 1.

[0103] In this embodiment, the working principle of the dishwasher is as follows:

[0104] Cathode: 2Cl - - 2e = Cl2

[0105] Anode: 2H2O + 2e - = H2 + 2OH -

[0106] Total reaction: 2Cl - + 2H2O = H2 + Cl2 + 2OH -

[0107] A disproportionation reaction will occur between chlorine and water: Cl2 + H2O = HCl + HClO. The generated HClO has certain oxidizing properties itself, thereby achieving the killing effect on bacteria and viruses.

[0108] In this embodiment, the salt used is NaCl, which is non-toxic and stable in nature, not prone to deterioration, and convenient for storage and electrolytic disinfection operations. For other chlorates, such as KCl, CaCl2, etc., since they will cause certain harm to the human body, they are not recommended for use.

[0109] In this embodiment, the structure of the brine generating device itself is not limited, as long as it is a device capable of generating brine. As an alternative embodiment, the brine generating device itself can be a structure that can simultaneously hold sodium chloride and fresh water. As a preferred embodiment, the brine generating device includes: a water softener 12, connected to the water tank chamber; a water inlet pipe 6, connected to the water softener 12, suitable for supplying water to the water softener 12. Correspondingly, a brine source needs to be connected at the water inlet pipe 6, and the brine is directly introduced into the water softener 12, and then enters the chamber structure again through the water softener 12, so as to realize the electrolysis operation. At the same time, a water inlet pipe solenoid valve 7 is provided on the water inlet pipe 6 to control the on-off of the water in the water inlet pipe 6.

[0110] Furthermore, in order to enable the water softener 12 to form a certain concentration of brine by itself and avoid setting a separate brine source, the water softener 12 includes a saturated brine chamber 9, and the water inlet pipe 6 is at least connected to the saturated brine chamber 9 of the water softener 12 and the chamber structure.

[0111] By setting the saturated brine chamber 9 in the water softener 12, the self-cleaning function of the water softener 12 can be realized through the saturated brine chamber 9. At the same time, by setting the saturated brine chamber 9, the brine inside the saturated brine chamber 9 can be fully utilized, so that the brine can be electrolyzed later and further form a disinfectant.

[0112] In this embodiment, the water softener 12 includes: a resin water softening chamber 8, and a resin water softening chamber inlet pipe 11 is provided between the resin water softening chamber 8 and the water inlet pipe 6; the saturated brine chamber 9, and a saturated brine chamber inlet pipe 20 is provided between the saturated brine chamber 9 and the water inlet pipe 6.

[0113] Specifically, the softening operation of the external water source can be realized through the resin water softening chamber 8. Through the saturated brine chamber 9, the self-cleaning operation of the resin water softening chamber 8 can be realized, and at the same time, the function of the brine source can be realized. At the same time, in order to realize the connection between the water inlet pipe 6 and the water softener 12, a three-way valve 10 is provided on the water inlet pipe 6. One end of the three-way valve 10 is connected to the water inlet pipe 6, and the other two ends are respectively connected to the resin water softening chamber inlet pipe 11 and the saturated brine chamber inlet pipe 20.

[0114] In this embodiment, the water inlet pipe 6 includes: a water tank soft water inlet pipe 18, connecting the resin water softening chamber 8 and the chamber structure; and a water tank saturated brine inlet pipe 19, connecting the saturated brine chamber 9 and the chamber structure.

[0115] Further, a flow meter 14 is provided on the soft water inlet pipe 18 of the water tank, and a metering pump 13 is provided on the saturated brine inlet pipe 19 of the water tank. Through the combination of the flow meter 14 and the metering pump 13, the flow rates of the water flowing out of the resin soft water chamber 8 and the saturated brine chamber 9 can be measured respectively.

[0116] In this embodiment, as a preferred implementation manner, as Figures 1 - 3 shown, the chamber structure includes: a water tank, and a water tank chamber is formed inside the water tank.

[0117] Further, in this embodiment, the water tank includes:

[0118] A confluence area 231, where the soft water inlet pipe 18 of the water tank and the saturated brine inlet pipe 19 of the water tank converge in the confluence area 231; by providing the confluence area 231, the clear water and brine flowing out of the water softener 12 can be mixed, thus facilitating the subsequent electrolysis operation. The shape of the confluence area 231 is not overly limited as long as the confluence operation can be achieved;

[0119] A disinfectant discharge port 232, to which a disinfectant discharge pipe 15 is connected, and a disinfectant discharge pipe solenoid valve 16 is provided on the disinfectant discharge pipe 15, which is adapted to discharge the disinfectant 22 in the water tank chamber into the inner tank 1, thereby realizing the subsequent disinfection and cleaning operations of the inner tank 1.

[0120] In this embodiment, correspondingly, the water tank includes: a soft water inlet 235, which is connected to the soft water inlet pipe 18 of the water tank; a brine inlet 234, which is connected to the saturated brine inlet pipe 19 of the water tank.

[0121] Specifically, the water tank includes: a first water tank side wall; a second water tank side wall, which is disposed opposite to the first water tank side wall, and the second water tank side wall is adjacent to the inner wall of the inner tank 1; a thick wall, which is clamped between the first water tank side wall and the second water tank side wall;

[0122] In this embodiment, the wall thickness refers to the side wall along the thickness direction of the water tank itself, and the wall thickness is annularly arranged. Correspondingly, one of the soft water inlet 235 and the brine inlet 234 is disposed on the second water tank side wall, and the other of the soft water inlet 235 and the brine inlet 234 is disposed on the thick wall.

[0123] In this embodiment, in order to achieve better drainage of the water entering the water tank, the water tank further includes a water channel 24, as Figure 6As shown in the figure, the water channel 24 refers to the part where the water diversion operation can be realized. Specifically, the water channel 24 includes a diversion section 241 and a rectification section 242. The rectification section 242 is arranged downstream of the diversion section 241, and the diversion section 241 is communicated with the confluence area 231; the drainage port 2421 is formed on at least one of the rectification section 242 and the diversion section 241.

[0124] Specifically, there are not too many restrictions on the shape and inner diameter of the water channel 24 itself. The shape of the water channel 24 itself can be limited according to the shape of the water tank. At the same time, the water channel 24 itself can be arranged at the edge position inside the water tank or at the position close to the center of the water tank. As a preferred implementation method, the water channel 24 itself is arranged at a position close to the wall thickness of the water tank, which helps to improve the overall neatness of the space inside the water tank.

[0125] In this embodiment, there are not too many restrictions on the position of the drainage port 2421 itself. It can be arranged on the rectification section 242 or on the diversion section 241. As a preferred implementation method, the drainage port 2421 is arranged on the rectification section 242. Through the above setting method, the height of the drainage port 2421 itself inside the water tank can be increased, and it can be avoided that when the water tank is filled with water, the disinfectant 22 prepared inside the water tank flows back into the water channel 24 through the drainage port 2421.

[0126] As a preferred implementation method, the drainage port 2421 is arranged at the top position of the water tank chamber and extends towards the inside of the water tank chamber.

[0127] Through the above setting method, it can be effectively avoided that the disinfectant prepared inside the water tank overflows from the water tank to the outside through the water channel 24 and causes pollution to the outside. There is no limit on the extension angle of the drainage port 2421 itself. Specifically, the included angle between the diversion section 241 and the rectification section 242 is less than 180°. As a preferred implementation method, the drainage port 2421 itself can extend towards the inside of the water tank chamber perpendicular to the horizontal direction.

[0128] In this embodiment, as Figures 4 - 9 shown, an overflow port 233 is arranged on the water tank, a through hole 101 is arranged on the inner liner 1 at a position corresponding to the overflow port 233, and an overflow exhaust structure is arranged between the overflow port 233 and the through hole 101. The overflow exhaust structure is suitable for restricting the substances in the water tank from flowing into the through hole 101 unidirectionally from the overflow port 233.

[0129] The overflow port 233 can achieve the following functions: when the water volume inside the water tank is excessive, the excess water can be drained from the water tank through the overflow port 233. At the same time, by setting the overflow port 233, the water volume inside the water tank can be detected, and then the water inlet b1 of the water tank can be controlled to stop the water inlet operation. Further, when an electrolytic reaction occurs inside the water tank, flammable gases such as hydrogen will be generated inside it. By setting the overflow port 233, the hydrogen can be quickly led out from inside the water tank to the outside, ensuring the safety of the water tank itself.

[0130] Further, the highly oxidizing disinfectant generated in the water tank itself is clean water, while the water in the inner tank 1 itself is turbid water, and a large amount of oil stains are mixed in the turbid water. At this time, it is necessary to prevent the water in the inner tank 1 from flowing back into the water tank and polluting the water in the water tank. Specifically, the through hole 101 can be integrally formed on the side wall of the inner tank 1, or can be set on the side wall of the inner tank 1 by means of post-processing. The through hole 101 is circularly arranged.

[0131] In this embodiment, the overflow and exhaust structure itself can be a one-way valve or a structure that realizes the one-way movement of fluid. As a preferred implementation manner, the overflow and exhaust structure includes:

[0132] The water and gas inlet a1, which is penetrated and arranged on the first side of the overflow and exhaust structure;

[0133] The water blocking end cover a2, which is arranged on the second side of the overflow and exhaust structure and is arranged along the extending direction of the water and gas inlet a1, and is suitable for blocking the extending direction of the water and gas inlet a1; specifically, the water blocking end cover a2 is arranged in the inner tank 1, and a cavity is arranged between the water blocking end cover a2 and the water and gas inlet a1, and

[0134] The overflow and exhaust port a3, which penetrates the overflow and exhaust structure along a direction parallel to the water blocking end cover a2 and is at least partially communicated with the water and gas inlet a1.

[0135] By setting the overflow and exhaust port a3, the gas or liquid acting on the water blocking end cover a2 can be guided, so that the gas or liquid finally enters the inner tank 1 at a certain angle.

[0136] In this embodiment, the liquid from the first side of the overflow exhaust structure overflows in a submerged manner, and the liquid from the second side of the overflow exhaust structure is ejected. After the water-blocking end cover a2 blocks the extending direction of the water-vapor inlet a1, an overflow exhaust port a3 is further formed on the second side of the overflow exhaust structure. At least a part of the overflow exhaust port a3 communicates with the water-vapor inlet a1, thereby internally penetrating and conducting the overflow exhaust structure, facilitating the liquid or gas entering the water-vapor inlet a1 from the first side of the overflow exhaust structure to be discharged from the overflow exhaust port a3 located on the second side of the overflow exhaust structure.

[0137] In the specific implementation process, the liquid or gas enters from the water-vapor inlet a1 on the first side of the overflow exhaust structure, passes through the internal channel of the overflow exhaust structure, and changes direction due to being blocked by the water-blocking end cover a2 on the second side of the overflow exhaust structure in the flow path of the liquid or gas. Finally, the liquid or gas is discharged from the overflow exhaust port a3. For the liquid or gas from the second side of the overflow exhaust structure, if it wants to enter the overflow exhaust structure, it must enter from the overflow exhaust port a3. The extending direction of the overflow exhaust port a3 is set at an angle with the extending direction of the water-vapor inlet a1. In this embodiment, the two are perpendicularly arranged, so that the liquid or gas from the second side of the overflow exhaust structure cannot enter the overflow exhaust structure in the parallel direction of the extending direction of the water-vapor inlet a1, thereby blocking the liquid or gas at a specific angle from the second side of the overflow exhaust structure.

[0138] In this embodiment, the overflow exhaust structure further includes: an anti-backflow rib a4, which is arranged on the conduction path between the overflow port 233 and the overflow exhaust port a3, and the anti-backflow rib a4 is adapted to at least partially block the overflow port 233. Thus, the liquid or gas at a specific angle from the second side of the overflow exhaust structure not only has to be blocked by the water-blocking end cover a2, but also has to be blocked again by the anti-backflow rib a4 after a small part of the liquid or gas enters the overflow exhaust port a3, reducing the occurrence of the situation where the liquid or gas enters the overflow exhaust structure due to splashing.

[0139] Specifically, as Figure 7 shown, the anti-backflow rib a4 is arranged at the lower edge position of the overflow port 233, and the lowest point position of the anti-backflow rib a4 in the up-down direction is higher than the lowest point position of the overflow exhaust port a3. In this embodiment, the anti-backflow rib a4 is arranged parallel to the water-blocking end cover a2.

[0140] Specifically, at least one notch is formed on the path where the diversion rib a5 surrounds the water and gas inlet a1. By forming at least one notch on the path where the diversion rib a5b612 surrounds the water and gas inlet a1, the connection between the notch of the diversion rib a5b612 and the water blocking end cover a2 can be disconnected, thus facilitating the formation of the water and gas inlet a1.

[0141] Specifically, the notch of the diversion rib a5 and the water blocking end cover a2 jointly enclose the overflow exhaust port a3. As Figures 7 - 8 shown, the exhaust path S2 and the overflow path S3 inside the overflow exhaust structure both enter from the water and gas inlet a1 and finally discharge from the overflow exhaust port a3.

[0142] In this embodiment, a spray arm 3 is provided in the inner tank 1, and the spray arm 3 is used to wash the dish basket and the tableware 2, fruits and vegetables placed on the dish basket. At the same time, the overflow exhaust structure itself is provided with a notch. Since the inner tank 1 is itself in the water spraying environment of the spray arm 3, it is very likely that the water in the spray arm 3 acts on the overflow exhaust structure through the notch. To prevent the above situation from occurring, in this embodiment, as Figure 10 shown, the included angle β1 between the exhaust and overflow direction S4 of the overflow exhaust port a3 and the horizontal plane is such that 0° ≤ β1 ≤ 180°. Preferably, 0° < β1 < 180°, so that the exhaust and overflow direction S4 of the overflow exhaust port a3 is arranged as much as possible downward, facilitating overflow and at the same time reducing the entry of liquid on the second side. The best range is 120° < β1 < 150°.

[0143] Through the above setting method, the water sprayed from the spray arm 3 cannot directly enter the overflow exhaust structure through the notch, thus avoiding the pollution of the overflow exhaust structure by the water in the inner tank 1.

[0144] Specifically, the dishwasher further includes:

[0145] A spray arm 3 adapted to spray water flow;

[0146] An overflow exhaust port a3 is provided on the overflow exhaust structure, and the value range of the included angle β2 between the opening direction of the overflow exhaust port a3 and the spraying direction of the spray arm 3 is 90° ≤ β2 ≤ 180°.

[0147] Preferably, at least a part of the spray arm 3 is arranged inside the inner tank 1. In this embodiment, the spray arm 3 is located at the middle position of the inner tank 1, and the water tank is installed on the side wall of the inner tank 1, so that the overflow exhaust structure is also located on the side wall of the water tank. The spray arm 3 sprays water by rotation, and the water spray direction S1 is as shown in the figure. In this embodiment, taking the clockwise rotation of the spray arm 3 as an example, that is, the high-pressure water column sprayed by the spray arm 3 is washed in the counterclockwise direction. At this time, the opening direction of the overflow exhaust port a3 is set in a direction substantially opposite to the spray direction of the spray arm 3, which can reduce the entry of the water flow sprayed by the spray arm 3 into the overflow exhaust structure, and further reduce the entry of the water flow sprayed by the spray arm 3 into the water tank.

[0148] In the dishwasher provided in this embodiment, by setting the opening direction of the overflow exhaust port a3 at an angle with the spray direction of the spray arm 3, and the specific value range is 90°≤β2≤180°, that is, the opening direction of the overflow exhaust port a3 is set in a direction substantially opposite to the spray direction of the spray arm 3, which can reduce the entry of the water flow sprayed by the spray arm 3 into the overflow exhaust structure, and further reduce the entry of the water flow sprayed by the spray arm 3 into the water tank.

[0149] In this embodiment, in order to realize the quick loading and unloading operation of the overflow exhaust structure itself, a tooling rib a6 is also provided on the overflow exhaust structure, and the tooling rib a6 is suitable for adjusting the orientation of the overflow exhaust port a3. Specifically, the tooling ribs are arranged radially on the overflow exhaust structure, and the number of the tooling ribs is not overly limited. As a preferred implementation manner, the tooling ribs are set to two, and the included angle between the tooling ribs and the overflow exhaust port a3 is 120°.

[0150] In this embodiment, an overflow port flange a7 is circumferentially arranged around the overflow port 233, and a screwing portion a8 is arranged at a position corresponding to the overflow port flange a7 on the overflow exhaust structure; an internal thread or an external thread is arranged on the overflow port flange a7, and a corresponding external thread or internal thread is arranged on the screwing portion a8.

[0151] Through the cooperation of the overflow port flange a7 and the screwing portion a8, the overflow exhaust structure can be installed on the water tank. Preferably, the overflow port flange a7 is arranged outside the water tank. As a variation, the overflow port flange a7 can also be arranged inside the water tank or on both sides of the first water tank side wall along the thickness direction. Correspondingly, the screwing portion a8 is located on the first side of the overflow exhaust structure, preferably at the circumferential position outside the water and gas inlet a1, which is convenient for directly connecting the water and gas inlet a1 with the overflow port 233.

[0152] Further, to prevent water from flowing out of the overflow exhaust structure, an overflow port seal ring a9 is also provided between the water tank and the inner tank 1, and the overflow port seal ring a9 surrounds the overflow port 233.

[0153] In this embodiment, the water in the water inlet pipe 6 will enter the inner tank 1 and the water tank 23 respectively. To achieve the water diversion operation, a water inlet three-way valve (not shown in the figure) is first provided on the water inlet pipe 6. The water flowing out through the water inlet three-way valve will be divided into two paths. One path is connected to the inner tank, and the other path is connected to the water softener. The water path leading to the water softener will enter the three-way valve 10, and then through the three-way valve 10, it will be divided into a resin water softening chamber water inlet pipe 11 and a saturated brine chamber water inlet pipe 20.

[0154] In this embodiment, as an implementation manner, the chamber structure itself can directly adopt a water tank structure. As another implementation manner, as Figure 11 and Figure 12 shown, the chamber structure further includes:

[0155] A respirator, the water tank is arranged inside the respirator. Specifically, the water tank is set separately in the respirator as a part of the respirator. At this time, the respirator itself can realize its own inherent functions. The respirator itself is connected to an external water source through a respirator water inlet pipe 6. The external water source can be a water tank or a tap water pipe. An inlet solenoid valve is provided on the respirator water inlet pipe 6. By controlling the on-off of the inlet solenoid valve, the water flow into the respirator can be controlled. At the same time, by placing the water tank, a functional component, inside the respirator, the electrolysis operation of the brine entering the respirator can also be realized. Therefore, by setting the respirator, the structure of separately setting a water tank in the dishwasher can be avoided, thereby effectively reducing the space occupied by the dishwasher itself and improving the structural compactness of the dishwasher.

[0156] In this embodiment, the respirator includes:

[0157] An inlet b1 and an outlet b2, and the electrolysis component 17 communicates with the inlet b1 and the outlet b2;

[0158] A breathing water path b4 is arranged inside the electrolysis component 17 and an electrolysis water path b3 is arranged separately from the breathing water path b4. The electrolysis component 17 is arranged on the electrolysis water path b3;

[0159] And a water path commutation structure b5, the water path commutation structure is adapted to open or close the breathing water path b4 and the electrolysis water path b3 so that the breathing water path b4 and the electrolysis water path b3 flow alternately.

[0160] Meanwhile, in order to introduce salt into the respirator, a salt inlet b6 is provided on the respirator. Solid salt is put into the respirator through the salt inlet b6. At the same time, the salt inlet b6 is arranged on the electrolysis water path b3, so as to drive the brine obtained by mixing salt and water to the electrolysis component 17, facilitating the electrolysis operation.

[0161] An electrolysis component 17 is arranged inside the traditional ventilator. The electrolysis component 17 realizes the preparation of disinfectant inside the ventilator by electrolyzing brine. The prepared disinfectant can enter the inside of the dishwasher to achieve comprehensive disinfection and sterilization of the dishwasher. Further, under the action of the water path commutation structure, the ventilator can perform different functions according to the needs of the dishwasher. When the dishwasher needs to be disinfected, the electrolysis water path b3 is opened. In other states, the breathing water path b4 is used.

[0162] In this embodiment, the dishwasher further includes:

[0163] A water cup 5 is arranged in the inner container 1. A disinfectant discharge port 232 is provided on the water tank. The disinfectant 22 flowing out of the disinfectant discharge port 232 enters the water cup 5. The water cup 5 is communicated with the spray arm 3. A washing pump 4 is arranged between the water cup 5 and the spray arm 3. By arranging the water cup 5, the disinfectant prepared inside the water tank is transferred to the inner container 1. The disinfectant in the inner container 1 is further transferred to the spray arm 3. The spray arm 3 sprays the disinfectant to various parts of the inner container 1 by rotating, so as to clean the tableware 2 in the inner container 1.

[0164] Further, the plane where the disinfectant discharge port 232 is located is higher than the upper surface of the water cup 5. There is a position difference between the plane of the water tank outlet b2 and the upper surface of the water cup 5, so that the disinfectant in the water tank can flow into the water cup 5 only under the action of gravity. And using the principle of communicating vessels, it can ensure that all the disinfectant in the water tank flows into the water cup 5, which is convenient for diluting the disinfectant in the water cup 5 according to a preset volume of water, avoiding the problem of inaccurate concentration of the effective components of the disinfectant.

[0165] The disinfection process of the dishwasher provided in this embodiment is as follows:

[0166] When the chamber structure is set as a water tank, the water inlet pipe 6 enters the water softener 12. At this time, the water in the resin water softening chamber inlet pipe 11 enters the resin water softening chamber 8, and the water in the saturated brine chamber inlet pipe 20 enters the saturated brine chamber 9. At this time, the water flowing out of the resin water softening chamber 8 is softened to form softened water. The water flowing out through the saturated brine chamber 9 forms brine itself due to mixing with the brine in the saturated brine chamber 9. The water flowing out of the two chambers converges at the confluence of the water tank, thus forming brine with a specific concentration. When the brine is completely mixed, it will further flow into the water channel 24. The brine passes through the drainage section 241 and the rectifying section 242 in sequence, and flows out from the drainage port 2421 of the rectifying section 242 into the interior of the water tank. As the brine in the water tank is continuously injected, the brine will gradually submerge the electrolysis assembly 17. At this time, the electrolysis operation of the brine is started, so that the brine generates disinfectant through the chemical reaction provided in this embodiment. When the preparation of the disinfectant is completed, it leaves the water tank through the disinfectant discharge port 232 and enters the inner tank 1, and the disinfection operation of the tableware 2 is realized through the water cup 5 and the spray arm 3 of the inner tank 1.

[0167] When the chamber structure is a respirator, the external water first enters the breathing water path b4 of the respirator, then leaves the breathing water path b4 and enters the water softener 12. At this time, the water in the resin water softening chamber inlet pipe 11 enters the resin water softening chamber 8, and the water in the saturated brine chamber inlet pipe 20 enters the saturated brine chamber 9. At this time, the water flowing out of the resin water softening chamber 8 is softened to form softened water. The water flowing out through the saturated brine chamber 9 forms brine itself due to mixing with the brine in the saturated brine chamber 9. The brine generated after mixing will enter the electrolysis water path b3 of the respirator again, and the electrolysis operation of the brine is further realized through the electrolysis device in the electrolysis water path b3. Then, the prepared disinfectant is transferred to the inner tank 1 through the water outlet b2.

[0168] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
