[0001] The present invention relates to the technical field of cleaning equipment, and particularly relates to a water tank and a dishwasher. Background Art

[0002] With the improvement of living standards, dishwashers have gradually entered ordinary families, improving our quality of life.

[0003] Generally, the main core components of existing dishwashers usually include: an inner tank assembly, a water cup assembly, a spray arm assembly, a filter assembly, a washing pump, a drainage pump, and pipelines, etc. Currently, dishwashers on the market generally perform main cleaning and tableware disinfection through high temperature (usually about 70°C), and some also configure UVC ultraviolet lamp disinfection, add silver ions to inhibit bacteria in the part materials, steam high-temperature disinfection, hot air drying, etc. Summary of the Invention

[0004] The present invention provides a water tank and a dishwasher.

[0005] A water tank, comprising:

[0006] A water tank chamber, including a water tank inlet and a water tank outlet communicating with the water tank chamber, and the water tank chamber further includes:

[0007] A kettle mouth part, the cross-sectional area of the water tank chamber becomes smaller at the kettle mouth part, and the water tank outlet is arranged inside the kettle mouth part.

[0008] The kettle mouth part is located at the bottom of the water tank chamber.

[0009] The kettle mouth part includes:

[0010] A kettle mouth inclined surface, arranged at one end of the kettle mouth part away from the water tank outlet, and the width of the kettle mouth part gradually becomes smaller along the extending direction of the kettle mouth inclined surface.

[0011] On the kettle mouth inclined surface, there is arranged:

[0012] A kettle mouth convex part, arranged on the kettle mouth inclined surface and protruding into the kettle mouth part.

[0013] The kettle mouth part includes:

[0014] A kettle mouth reinforcing rib structure, the kettle mouth reinforcing rib structure at least includes a first kettle mouth reinforcing rib and a second kettle mouth reinforcing rib, and a kettle mouth channel is formed between the first kettle mouth reinforcing rib and the second kettle mouth reinforcing rib.

[0015] The first kettle mouth reinforcing rib is in a broken line shape, and a triangular reinforcing structure is formed between the first kettle mouth reinforcing rib and a side of the kettle mouth part.

[0016] The first spout reinforcing rib is provided on the spout inclined surface.

[0017] One end of the spout channel close to the water outlet of the water tank is provided with a spout diameter-changing part, and the width of the spout channel gradually increases in the direction of the water outlet of the water tank at the spout diameter-changing part.

[0018] It further includes:

[0019] The first rib is provided inside the spout part, and there is at least one gap for water flow between the first rib and the side wall of the spout part.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. The present invention provides a water tank, including: a water tank chamber, including a water tank inlet and a water tank outlet communicating with the water tank chamber. The water tank chamber further includes: a spout part, the cross-sectional area of the water tank chamber becomes smaller at the spout part, and the water tank outlet is provided inside the spout part.

[0022] The water tank chamber is used to store or temporarily store water and / or disinfected water for use in a dishwasher, and the disinfected water can be dissolved and prepared in the water tank. When the water tank chamber drains water, the cross-sectional area of the spout part is smaller than the cross-sectional area inside the water tank, which plays a guiding role and a guiding and converging role before passing through the water tank outlet, so that the water or disinfected water passes through the spout part before flowing out of the water tank outlet. If filtration or other functions need to be performed on the water or disinfected water, it can be carried out in the spout part area.

[0023] 2. In the water tank provided by the present invention, the spout part is located at the bottom of the water tank chamber.

[0024] When the spout part is located at the bottom of the water tank chamber, no external force needs to be applied when the water tank chamber drains water. When the water tank outlet is opened, the water or disinfected water can drain by itself under gravity.

[0025] 3. In the water tank provided by the present invention, the spout part includes: a spout inclined surface provided at one end of the spout part away from the water tank outlet, and the width of the spout part gradually becomes smaller along the extending direction of the spout inclined surface.

[0026] The spout inclined surface plays a guiding role and can guide the water or disinfected water on both sides of the opening area of the spout part to flow into the spout part.

[0027] 4. In the water tank provided by the present invention, the spout inclined surface is provided with: a spout convex part provided on the spout inclined surface and protruding into the spout part.

[0028] Due to the guiding function of the spout inclined plane, water or disinfectant water first impacts on the spout inclined plane and then flows along the inclined surface of the spout inclined plane. Therefore, the spout convex part can fully impact with the water flow or disinfectant water flowing along the spout inclined plane. When there are undissolved salt blocks in the water or disinfectant water, the salt blocks are scattered by the impact on the spout convex part and thus fully dissolved, preventing the salt blocks in the solution from entering the spout part and blocking the water outlet of the water tank. On the other hand, the part adjacent to the spout part is the local structure where the water inlet of the water tank is located. A flow meter is arranged at the water inlet of the water tank to monitor the water inflow of the water tank chamber. When the installation structure of the flow meter is a structure such as a groove, it can be correspondingly arranged on the back of the spout convex part. The part where the spout convex part is located is relatively thick and has good mechanical strength, which can improve the installation reliability of other components such as the flow meter. In addition to guiding the water flow, the inclined plane can also provide an installation foundation for other components of the whole machine, improving the compactness of the overall mechanical structure.

[0029] 5. The water tank provided by the present invention, wherein the spout part includes: a spout reinforcing rib structure, and the spout reinforcing rib structure at least includes a first spout reinforcing rib and a second spout reinforcing rib, and a spout channel is formed between the first spout reinforcing rib and the second spout reinforcing rib.

[0030] The spout channel can further narrow the cross-sectional area through which water or disinfectant water flows, and rectify in advance before the water or disinfectant water enters the water outlet of the water tank. On the other hand, the spout reinforcing rib has a certain height, and the spout reinforcing rib can support between the first water tank side wall and the second water tank side wall of the water tank, improving the strength of the water tank chamber.

[0031] 6. The water tank provided by the present invention, wherein the first spout reinforcing rib is in a zigzag shape, and a triangular reinforcing structure is formed between the first spout reinforcing rib and a side edge of the spout part.

[0032] The triangular reinforcing structure can improve the mechanical strength of the spout part.

[0033] 7. The water tank provided by the present invention, wherein the first spout reinforcing rib is arranged on the spout inclined plane.

[0034] The triangular reinforcing structure can further improve the mechanical strength of the spout inclined plane. Description of the Drawings

[0048] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Embodiment 1

[0050] This embodiment provides a dishwasher, as Figure 1 shown, including:

[0051] A water tank b0, which is internally provided with a water tank chamber b901. A salt inlet b10 is provided on the water tank chamber b901. Specifically, the salt inlet b10 is used to add salt or brine into the water tank chamber b901. In one embodiment, the salt inlet b10 can be used to connect the water tank chamber b901 with a brine generating device. The brine generating device can deliver salt or brine into the water tank chamber b901 through the salt inlet b10. When the brine generating device delivers brine into the water tank chamber b901 through the salt inlet b10, the brine can be prepared inside the brine generating device or directly put the pre-prepared salt solution into the brine generating device.

[0052] Specifically, in this embodiment, an electrolysis assembly c0 is further provided in the water tank b0, which is arranged inside the water tank chamber b901 and is adapted to perform electrolysis operation on the brine generated by the brine generating device.

[0053] Based on the above embodiments, as a further limited embodiment, the dishwasher further includes an inner container d5. The water tank b0 is communicated with the inner container d5, and the water tank b0 can supply cleaning liquid to the inner container d5. The inner container d5 is suitable for placing tableware to be cleaned. The inner container d5 is provided with an open mouth by itself, and a door body is arranged on the open mouth to close the inner container through the door body. In order to facilitate the placement of tableware, several layers of bowl baskets distributed along the height direction can also be arranged in the inner container d5. As an alternative embodiment, the bowl baskets can either be detachably installed in the inner container d5 in various specifications or integrally formed in the inner container d5.

[0054] For the water tank b0 itself, in order to facilitate water inlet and outlet, a water tank inlet b7 and a water tank outlet b8 are usually provided. In this embodiment, the water tank inlet b7, the water tank outlet b8, and the salt inlet b10 form three openings on the water tank body b9. As an alternative embodiment, the salt inlet b10 can share the same opening on the water tank body b9 with the water tank inlet b7. At this time, water can be injected into the water tank chamber b901 through the water tank inlet b7, brine can be injected into the water tank chamber b901 through the water tank inlet b7, and salt can also be replenished into the water tank chamber b901 through the water tank inlet b7.

[0055] There is no excessive limitation on the positional relationship between the water tank b0 and the inner container d5. For example Figure 1 as shown, the water tank can be directly arranged outside the inner container. In one embodiment, the water tank b0 is arranged at the side wall position of the inner container. In other embodiments, the water tank b0 can also be arranged at the top wall position of the inner container. Further, the water tank b0 can also be arranged on the door body. As a preferred embodiment, the water tank is correspondingly arranged at the side wall position of the inner container, that is Figure 1 as shown, the water tank is arranged at the left side wall position of the inner container. Correspondingly, the water tank can also be arranged at the right side wall position of the inner container. As another alternative embodiment, the water tank b0 can also be arranged inside the inner container.

[0056] There is no specific limitation on the shape of the water tank b0. Based on the above embodiments, as a further limited embodiment, Figure 1 as shown, the upper part of the water tank b0 is rectangular, and the position corresponding to the top of the water tank is arc-shaped. As an alternative embodiment, Figure 1 from the perspective shown in Figure 1 , that is, looking directly at the water tank from the left side of the inner container d5, the water tank b0 is rectangular. As another alternative embodiment, the water tank b0 can also be circular, oval, diamond-shaped or other irregular shapes

[0057] in the perspective of Figure 1As shown, the width of the bottom of the water tank b0 is relatively small. On the one hand, it is to facilitate the water outlet of the water tank, that is, the water in the water tank can flow downward by its own gravity, and the narrowing of the bottom width of the water tank can play a guiding role. On the other hand, the narrowing of the bottom can reserve more space on the side wall of the inner tank, which is convenient for installing other structures. For the water tank of a dishwasher, it usually can include a water softening mechanism. In this embodiment, the narrowing of the bottom of the water tank b0 reserves more space for the installation of other components such as a water softener, a respirator, and a flow meter i. As an alternative implementation, the bottom width of the water tank b0 is relatively increased, or the width of the water tank b0 is the same in the height direction.

[0058] As Figure 1 shown, the water tank b0 has a certain thickness to form an internal water tank chamber b901, and the overall water tank b0 is arranged parallel to the outer side wall of the inner tank. Combining Figure 1 , it can be seen that the thickness of the water tank b0 is uniform in its own thickness direction. The thickness direction of the above-mentioned water tank b0 can be understood as Figure 1 shown in, the direction from the surface of the water tank b0 close to the side wall of the inner tank to the other side far from the side wall of the inner tank d5. As an alternative implementation, the thickness of the water tank b0 is not uniform in its thickness direction. Specifically, it can be that one side of the water tank b0 close to the inner tank d5 is parallel to the inner tank d5, and the other side is inclined towards the inner tank d5, so that the thickness of the space inside the water tank b0 gradually changes in the height direction of the water tank b0, thereby forming a water tank chamber b901 with a changing thickness. The change in the shape and thickness of the water tank chamber b901 is, on the one hand, for the installation of internal components and the exertion of the functions of internal components; on the other hand, it is for the installation and connection of the water tank b0 with other mechanisms of the dishwasher to form a structural cooperation, thereby saving space and increasing the compactness of the internal structure.

[0059] Furthermore, the water tank chamber b901 inside the water tank b0 is used to store and prepare the cleaning liquid. The cleaning liquid for a dishwasher can be water, brine, a cleaning agent for removing dirt and oil, disinfectant water, etc. The cleaning liquid is usually transported to the use location through a pipeline structure, and different cleaning modes may also correspond to different cleaning liquid temperatures. Therefore, if the cleaning liquid inside the water tank b0 needs to be heated, the outer shell of the water tank b0 can be reserved with a groove structure and / or a protrusion structure, so that the pipeline structure can pass through the groove and / or the protrusion. When the cleaning liquid inside the water tank b0 is heated, the medium in the pipeline structure can be assisted in heating to save energy.

[0060] In this embodiment, the water tank b0 includes a water tank body b9 and other components arranged inside the water tank body b9. The water tank body b9 can be understood as the shell structure of the water tank b0. As Figure 1 , Figure 5As shown, the water tank body b9 includes a first water tank side wall b904 and a second water tank side wall b905. The first water tank side wall b904 is arranged parallel to the side wall of the inner tank d5. On both the first water tank side wall b904 and the second water tank side wall b905, there are protruding mating rabbet structures, as Figure 5 shown, the second water tank side wall b905 is buckled on the first water tank side wall b904 to form a relatively enclosed water tank chamber b901 inside the water tank body b9. As an alternative implementation of the structure of the water tank body b9, the water tank body b9 can be composed of three or more components combined. As another alternative implementation of the structure of the water tank body b9, the outer shell of the water tank body b9 is integrally formed as a whole.

[0061] In the dishwasher of this embodiment, the cleaning liquid inside it includes disinfectant water, and the preparation principle of the disinfectant water is as follows: Cathode: 2Cl--2e=Cl2

[0062] Anode: 2H2O + 2e-=H2 + 2OH-

[0063] Total reaction: 2Cl- + 2H2O=H2 + Cl2 + 2OH-

[0064] A disproportionation reaction will occur between chlorine gas and water: Cl2 + H2O=HCl + HClO. The generated HClO has certain oxidizing properties itself, thus achieving the killing effect on bacteria and viruses.

[0065] In this embodiment, the main component of the salt used is NaCl, which is non-toxic and has stable properties by itself, is not prone to deterioration, and is convenient for storage and electrolytic disinfection operations. For other chlorates, such as KCl, CaCl, etc., since they will cause certain harm to the human body, it is not recommended to use them.

[0066] On the basis of the above-mentioned implementation, as a further limited implementation, the brine generating device is arranged inside the water tank b0. The brine generating device can provide brine or be used to provide the raw materials for preparing brine to support the preparation and transportation of brine. At this time, the user can supplement salt or brine into the brine generating device through the salt feeding port b10. On the basis of the salt feeding port b10 being connected to the brine generating device, the brine generating device can be directly arranged on the salt feeding port b10, or can be arranged downstream of the salt feeding port b10 to receive the salt or brine put in through the salt feeding port b10. As an alternative implementation, the brine generating device can also be arranged outside the water tank, and the brine generating device can be connected to the water tank b0 through a pipeline structure. As another alternative implementation, the brine generating device is arranged on the outer wall of the water tank and is connected to the inside of the water tank through structures such as rabbets.

[0067] There is no restriction on the specific structure of the brine generating device. Based on the above embodiments, as a further defined embodiment, as Figure 1 shown, the brine generating device is a salt dispenser in this embodiment. The salt dispenser can dispense salt or brine into the water tank chamber b901 through the salt dispensing port b10. In this embodiment, the specific structure of the salt dispenser is the accommodating groove a1, which is arranged on the salt dispensing port b10. Salt can be accommodated in the accommodating groove a1. After the water tank is filled with water, the water contacts the salt and dissolves the salt in the water tank chamber b901 to form brine for the electrolysis component c0 to prepare disinfected water. As an alternative embodiment, the salt dispenser is a pipeline structure. One end of the pipeline structure is connected to the water tank b0, and the other end extends to the outside of the dishwasher, facilitating the user to dispense salt into the water tank b0 from the outside of the dishwasher.

[0068] There is no specific restriction on the installation position of the accommodating groove a1. Based on the fact that the accommodating groove a1 is located inside the water tank b0, as a further defined embodiment, as Figure 1 shown, the accommodating groove a1 is arranged on the first water tank side wall b904. As an alternative embodiment, the accommodating groove a1 is arranged on the second water tank side wall b905. As another alternative embodiment, the accommodating groove a1 is arranged on other inner walls of the water tank chamber b901.

[0069] To facilitate replenishing salt into the accommodating groove a1, based on the above embodiments, as a further defined embodiment, as Figure 1 shown, the accommodating groove a1 is detachably connected to the water tank body b9, enabling the user to detach the accommodating groove a1 from the water tank b0 and replenish salt into the accommodating groove a1 from the outside of the dishwasher. Since the first water tank side wall b904 on the water tank b0 is close to the outer wall of the inner tank d5, an opening channel is provided through the water tank side wall and the inner tank d5, facilitating the passage of the accommodating groove a1. The opening channel forms the salt dispensing port b10 on the first water tank side wall b904. A sealing structure is provided between the water tank, the inner tank, and the accommodating groove a1 to ensure that the accommodating groove a1 enters the water tank by passing through the side wall of the inner tank d5 and the first water tank side wall b904 in sequence from the inside of the inner tank d5. When the brine generating device is used to provide brine, the brine can be directly introduced into the water tank chamber b901 through the above salt dispensing port b10. As an alternative embodiment, the accommodating groove a1 can also be arranged on the second water tank side wall b905. A corresponding channel or opening structure for the accommodating groove a1 to pass through is provided on the dishwasher housing, facilitating the user to directly install the accommodating groove on the water tank body b9 from the outside of the dishwasher, thereby replenishing salt into the water tank chamber b901. As another alternative embodiment, the accommodating groove can also be arranged on other side walls of the water tank chamber b901.

[0070] To facilitate the dissolution efficiency of salt and water, the accommodating groove a1 can be rotatably clamped to the water tank body b9. After the user adds salt into the accommodating groove a1, the accommodating groove a1 with the opening facing upward is inserted into the water tank chamber b901. When it is inserted to the rotation position, it is rotated and tightened. Combining Figure 2 、 Figure 3 , at this time, the opening direction of the accommodating groove with the opening facing upward is inclined or the opening faces downward, so that the surface of the salt pile in the accommodating groove is spread over a larger area. When the inclination angle is relatively large, part of the salt will directly fall into the water tank chamber b901. When the opening of the accommodating groove a1 is completely downward, most of the salt falls into the water tank chamber b901. When the water tank chamber b901 is filled with water through the water inlet b7 of the water tank, the water gradually accumulates in the water tank, and the flowing water contacts the salt that has fallen into the water tank chamber b901, thereby dissolving the salt.

[0071] There is no specific limitation on the setting position of the accommodating groove a1. On the basis of the above embodiments, as a further limited embodiment, as Figure 1 shown, the accommodating groove a1 is arranged in the upper half of the water tank chamber b901. As an alternative embodiment, the accommodating groove a1 is arranged in the lower half of the water tank chamber b901, and the accommodating groove a1 can be arranged close to the inner wall of the water tank chamber b901. Further, the accommodating groove a1 can share the same side wall structure with the water tank chamber b901.

[0072] In this embodiment, the water inlet b7 of the water tank is used for the water filling function of the water tank b0, and the water outlet b8 of the water tank is used to connect to the inner tank d5. The dishwasher of this embodiment further includes a water cup, and the water cup is used to supply water to the inner tank d5. The water outlet b8 of the water tank is used to supply water to the water cup, and the water outlet b8 of the water tank is connected to the water cup through a pipeline structure. In order to meet the temperature requirements of various washing modes, a heating device can be arranged in the water tank b0, in the water cup, or on the pipeline structure between the water tank and the water cup.

[0073] There is no specific limitation on the setting position of the water outlet b8 of the water tank. On the basis of the above embodiments, as a further limited embodiment, as Figure 1 shown, the water outlet b8 of the water tank is arranged at the bottom of the water tank. With this setting method in this embodiment, even without installing a pump body, the water in the water tank chamber b901 can be automatically discharged by gravity after the valve is opened, and is discharged through the drain pipe d42 connected to the water outlet b8 of the water tank. As an alternative embodiment, the water outlet b8 of the water tank is arranged at any position on the inner wall of the water tank chamber b901, and drainage can be achieved by matching the drain pipe d42 with a pump body structure.

[0074] There is no specific limitation on the setting position of the water inlet b7 of the water tank. On the basis of the above embodiments, as a further limited embodiment, as Figure 1As shown, the water inlet b7 of the water tank is provided at the bottom of the water tank chamber b901. Specifically, the water inlet b7 of the water tank is adjacent to the water outlet b8 of the water tank. Since both the water inlet b7 and the water outlet b8 of the water tank need to be connected to pipeline structures for use, the adjacent water inlet b7 and water outlet b8 of the water tank facilitate the unified reservation of space and the setting of pipeline structures at the corresponding positions of the dishwasher. As an alternative implementation, the water inlet b7 of the water tank is provided at any position on the inner wall of the water tank chamber b901.

[0075] On the basis of the above implementation, as a further limited implementation, as Figure 1 shown, since there is a receiving groove a1 in the water tank chamber b901 and there is salt to be dissolved in the receiving groove a1, in order to improve the dissolution efficiency of the salt, a water channel b5 is provided in the water tank b0. As Figure 2 、 Figure 3 shown, a drain port b501 is formed on the water channel b5, and the opening of the drain port b501 is arranged facing the opening of the receiving groove a1. As Figure 1 shown, when the water tank b0 is filled with water, water is introduced into the water channel b5 from the water inlet b7 of the water tank, and then discharged through the drain port b501, and the water flow directly flushes into the receiving groove a1. Therefore, during the water filling process, the receiving groove a1 is always washed, so that the salt is always in full contact with the flowing water, thereby accelerating the dissolution efficiency of the salt. On the other hand, if part of the salt in the receiving groove a1 condenses into salt lumps, it can be broken under the direct impact of the water flow, thereby further accelerating the dissolution of the salt.

[0076] Among them, multiple drain ports b501 can be formed on the water channel b5 in the above embodiment. The drain port b501 can be open or provided with a valve switch, so as to realize the switching between opening and closing of the drain ports b501. The inner diameters of the multiple drain ports b501 can be the same or different, and drain ports with different inner diameters can correspondingly form water flow columns with different intensities for users to switch and use.

[0077] There is no specific limitation on the shape of the drain port b501. In this embodiment, as Figure 2 、 Figure 3 shown, the inner wall of the drain port is straight to form a linear water channel. It can reduce the friction force received when the water flow flows along the inner wall of the drain port. When the water flow flows in the drain port b501, it can continuously receive the push of the subsequent water flow in the water channel, so that the water is accelerated in the drain port b501 and the impact force of the water discharged from the drain port is improved. As an alternative implementation, the drain port b501 is parabolic or arc-shaped, and the inner wall of the drain port is smooth. As another alternative implementation, the drain port b501 is zigzag.

[0078] There is no specific limitation on the shape of the water channel b5. In this embodiment, as Figure 1As shown in the figure, the water channel b5 includes a diversion section b502 and a rectification section b503, and the drain opening b501 is formed on at least one of the diversion section b502 and the rectification section. The diversion section b502 can introduce water flow from the water inlet into the water tank chamber b901, and the rectification section b503 can guide and adjust the direction of the water flow, so as to output a columnar water flow. When the water tank b0 has a structure such as a receiving groove for accommodating salt, the water column formed by directional impact through the diversion section b502 or the rectification section of the water channel enables the salt to come into contact with water more fully under the impact of the water column and dissolve in the water. As an alternative implementation, the water tank b0 does not have a receiving groove a1, and salt is directly sprinkled into the water tank chamber b901 through the salt inlet b10 and accumulates at the bottom of the water tank chamber b901. At this time, the drain opening b501 sprays water towards the accumulated salt, making the water contact and dissolve the salt, and causing the local water flow to flow violently under the impact, thereby accelerating the dissolution of the salt. When water is injected into the water tank b0 to impact the salt to form a salt solution, or the salt solution is directly injected through the drain opening b501, the water in the water tank is electrolyzed in the water tank or sent into the electrolysis assembly to form disinfected water. While using the disinfected water to disinfect the tableware in the dishwasher, the pipes through which the disinfected water flows are also disinfected and sterilized. Therefore, even if there is disinfectant involved, bacteria will not grow.

[0079] On the basis of the above implementation, as a further limited implementation, as Figure 1 shown, the drain opening is provided on the rectification section b503. The overall shape of the rectification section b503 enables water to flow from a direction with higher gravitational potential energy to a direction with lower gravitational potential energy. On the one hand, the water in the diversion section forms a thrust on the water in the rectification section b503, and on the other hand, the gravitational potential energy is converted into kinetic energy, so that the water flowing out of the rectification section b503 has a stronger ability to impact the salt. When there are agglomerated salt blocks in the salt, they can be more easily dispersed and dissolved in the water to form a salt solution. As an alternative implementation, the drain opening is provided on the diversion section b502. As another alternative implementation, when there are multiple drain openings, they can be respectively distributed on the diversion section b502 and the rectification section b503.

[0080] No specific limitation is imposed on the positional relationship between the diversion section b502 and the rectification section b503. On the basis of the above implementation, as a further limited implementation, as Figures 1 - 3 shown, the included angle between the diversion section b502 and the rectification section b503 is less than 180°, and a functional area b903 is formed between the diversion section b502 and the rectification section b503. As an alternative implementation, the included angle between the diversion section b502 and the rectification section b503 is equal to 180°, or greater than 180°.

[0081] No specific limitation is imposed on the shape of the rectification section b503. On the basis of the above implementation, as a further limited implementation, asFigure 1 As shown, the rectifying section b503 is arc-shaped. As an alternative embodiment, as Figure 2 shown, the rectifying section b503 is straight or zigzag-shaped. The shape of the zigzag can refer to shapes such as "M", "N", "V", etc. This is not elaborated in this embodiment. Those skilled in the art can change the shape of the rectifying section b503 based on the above examples to optimize the water path and improve the water injection efficiency and the salt dissolution efficiency. As another alternative embodiment, the rectifying section b503 is wavy.

[0082] Specifically, the functional area b903 is located at a relatively high horizontal position inside the water tank chamber b901. An overflow port b6 is provided in the functional area b903. When the water volume inside the water tank is too much, the excess water can be drained from the water tank through the overflow port b6. At the same time, by setting the overflow port b6, the water volume inside the water tank can be detected, and then the water inlet b7 of the water tank can be controlled to stop the water inlet operation. The reason for setting the functional area relatively at the top of the water tank chamber b901 is to reserve a part of the space at the top of the water tank on the premise that the water tank chamber b901 can meet the capacities of water, brine, and disinfectant solution. After the liquid levels of water, brine, and disinfectant solution reach the set capacities, they are below the functional area, so that the overflow port can fully play the roles of overflow and exhaust. When an electrolysis reaction occurs inside the water tank, flammable gases such as hydrogen will be generated inside it. By setting the overflow port b6, the hydrogen can be quickly led out from inside the water tank to the outside, ensuring the safety of the water tank itself. For the dishwasher itself, an exhaust structure can be set inside the dishwasher to cooperate with the overflow port to complete the exhaust function.

[0083] Furthermore, in this embodiment, as Figure 2 、 Figure 3 shown, the drain port b501 is arranged side by side with the overflow port b6. The drain port b501 can play a role in dividing the functional area b903 inside the water tank chamber b901. The side wall of the overflow port b6 adjacent to the drain port b501 is arranged side by side with the drain port b501, so that the horizontal height of the overflow port is not lower than the height of the water outlet of the drain port b501, thereby preventing the water discharged from the drain port b501 from overflowing through the overflow port b6.

[0084] Since it takes a certain amount of time for salt to dissolve, some salt carried out by the water flow from the accommodating groove exists in salt lumps. The dissolution speed of salt lumps in water is relatively slower than that of small salt grains, resulting in the salt lumps being prone to sedimentation towards the bottom of the water tank. Since the water outlet b8 of the water tank is located at the bottom of the water tank chamber b901, the salt lumps are prone to accumulate at the water outlet b8 of the water tank, causing the water outlet b8 of the water tank to be blocked.

[0085] Based on the above embodiments, a rectifying structure is also provided in the water tank b0, as Figures 1 - 3As shown, the rectifying structure is provided on the inner wall of the water tank chamber b901, specifically on the first water tank side wall b904 in this embodiment. The rectifying structure includes at least one rib. The rib is located on the flow path of the salt and upstream of the water tank outlet. The water flow bypasses at the rectifying structure and forms at least one bypass path. When the water tank discharges salt into the water tank chamber b901 through the salt inlet b10, the ribs of the rectifying structure form paths for the salt and the water flow to bypass, which can intercept salt blocks on the path of the salt flowing towards the outlet, causing the salt blocks to collide and disperse or extending the time for the salt to reach the outlet. When the salt blocks are collided and dispersed, it is equivalent to increasing the contact area between the salt blocks and the solution, accelerating the dissolution of the salt blocks. When the time for the salt blocks to reach the outlet increases, the flowing time of the salt in the solution is increased, enabling the salt blocks to dissolve more fully before reaching the outlet, thus further solving the problem that the salt blocks are prone to clogging the outlet.

[0086] Specifically, as Figure 1 shown, the rectifying structure includes: the first rib b1, which is arranged close to the water tank outlet b8. The first rib b1 is arranged close to the water tank outlet b8, which can intercept and disperse the salt blocks flowing towards the outlet at the outlet and force the salt blocks to bypass and dissolve fully.

[0087] There is no specific limitation on the setting method of the first rib b1. On the basis of the above embodiment, as a further defined embodiment, as Figure 1 shown, the first rib b1 is arranged horizontally. As an alternative embodiment, the first rib b1 is arranged obliquely.

[0088] On the basis of the above embodiment, as a further defined embodiment, as Figure 1 shown, the rectifying structure further includes: the second rib b2, which is arranged between the downstream of the salt inlet b10 and the upstream of the first rib b1. The second rib b2 can disperse and intercept the salt blocks before the salt blocks reach the first rib b1. When the salt blocks bypass the second rib b2, they can contact and dissolve with the solution more fully, further increasing the function of the rectifying structure to intercept and disperse the salt blocks and promote dissolution.

[0089] There is no specific limitation on the number of the second ribs b2. On the basis of the above embodiment, as a further defined embodiment, as Figure 1As shown, there are two second ribs b2, and there is a gap between the two second ribs b2, and the gap forms a baffle channel between the two second ribs b2. The baffle channel formed by the two second ribs b2 can guide salt blocks into the channel on one hand. On the other hand, for salt blocks with larger sizes, they can be temporarily intercepted at the opening of the baffle channel. When a salt block gets stuck at the opening of the baffle channel, with the inflow of water or the outflow of salt solution, the solution in the water tank chamber is still in a flowing state, and the salt block can be accelerated to dissolve or break under the impact of the water flow.

[0090] There is no specific limitation on the positional relationship of the second rib b2. On the basis of the above-mentioned embodiment, as a further defined embodiment, as Figure 1 shown, at least one of the second ribs b2 is inclined towards the salt inlet. When salt is put through the salt inlet, since the second rib b2 is arranged towards the salt inlet b10, during the falling process of the salt in the water tank chamber b901, the salt will hit the second rib b2, and the salt block is easy to disperse and not easy to form lumps. When salt solution is injected through the salt inlet b10, the salt solution falls on the second rib b2, and the second rib b2 has a guiding and buffering effect, preventing the salt solution from directly falling on the bottom of the water tank chamber b901, and a large drop will form an impact splash in the water tank.

[0091] There is no specific limitation on the positional relationship between the second rib b2 and the first rib b1. On the basis of the above-mentioned embodiment, as a further defined embodiment, as Figure 1 shown, at least a part of the second rib b2 covers the upstream of the gap between the first rib b1 and the inner wall of the water tank chamber. At least a part of the second rib b2 is distributed above the first rib b1, which can play a role of blocking the falling of the salt block or the falling of the salt block with the flow of water layer by layer, further enhancing the blocking and accelerating dissolution effect of the rectifying component on the salt block. On the other hand, the layer-by-layer blocking setting method can continuously promote the formation of a baffle in the water flow direction, thereby forming local turbulence inside the water body and further promoting the dissolution of the salt block.

[0092] There is no specific limitation on the structure of the ribs in the rectifying structure, such as the first rib b1 and the second rib b2. On the basis of the above-mentioned embodiment, as a further defined embodiment, a number of convex structures are provided on the rib. The convex structure can increase the pressure exerted on the salt block when it comes into contact with the salt block during the contact process, promoting the fragmentation and decomposition of the salt block. At the same time, the convex can play a role in intercepting the salt block, so that the salt block is intercepted on the gap between the convexes. As an alternative embodiment, the rib is a strip array structure composed of multiple columnar units. There is a gap for intercepting salt blocks between adjacent columnar units. As another alternative embodiment, the rib is a mesh plate structure.

[0093] Based on the above embodiments, as a further limited embodiment, the first rib b1 and the second rib b2 can extend from the first side wall b904 of the water tank to the second side wall b905 of the water tank. After the second side wall b905 of the water tank is cooperatively installed with the first side wall b904 of the water tank, the first rib b1 and the second rib b2 play a supporting role on the first side wall b904 and the second side wall b905 of the water tank, thereby improving the strength of the water tank body b9.

[0094] In this embodiment, in order to achieve the full dissolution of salt in the accommodating groove a1, a plurality of flow holes a103 are provided at the bottom of the accommodating groove a1. The flow holes are arranged at the bottom of the groove, which can ensure that the solution generated in the accommodating groove a1 can completely flow out, preventing the bottom liquid from remaining in the accommodating groove and causing the subsequent disinfectant solution concentration to not meet the standard.

[0095] There are no excessive limitations on the quantity, arrangement mode and shape of the flow holes themselves. In terms of the arrangement mode, other arrangement modes can be adopted, such as being arranged in a ring shape, a triangle shape, etc. As a preferred embodiment, a plurality of the flow holes a103 are arranged in a side-by-side straight line at the bottom of the accommodating groove a1. At the same time, in terms of the shape, the flow holes themselves can adopt regular shapes, such as rectangles, ellipses, etc., or irregular shapes, as long as the leakage function can be achieved. As a preferred embodiment, the flow holes themselves adopt circular shapes. At the same time, the aperture range of the circular holes is greater than or equal to 0.5 mm and less than or equal to 5 mm. Through the above size setting method, it is prevented that the salt particles directly pass through the flow holes and escape from the accommodating groove.

[0096] As a preferred embodiment, in this embodiment, as Figure 3 shown, the projection of the drain port 501 coincides with the flow hole a103. Specifically, the drain port 501 is arranged directly above the flow hole. Through the above setting method, the water flowing out from the drain port b501 can directly act on the position of the flow hole a103. At this time, the water has a large kinetic energy under the action of gravity. Therefore, after flushing the salt, the brine can be directly discharged from the flow hole a103, thereby improving the preparation efficiency of the brine.

[0097] In order to facilitate the drainage function of the water tank b0 and prevent the water outlet from being blocked, as Figure 1 、 Figure 4 shown, the water tank has a spout portion b902 with a gradually narrowing width at the bottom.

[0098] There is no specific limitation on the setting position of the spout portion b902. As Figure 4As shown, in this embodiment, the kettle mouth part b902 is correspondingly arranged below the salt feeding port b10 and / or the salt feeder. When water, electrolyte solution, or disinfected water is directly injected into the interior of the water tank chamber through the salt feeding port, the water flow will not directly impact the kettle mouth part. Instead, it is buffered by the first rib, preventing the formation of foam during water injection. The first rib b1 can be arranged close to the opening of the kettle mouth part or inside the kettle mouth part. There can be multiple first ribs, and the multiple first ribs are distributed inside the kettle mouth part and at the part of the water tank chamber b901 close to the opening of the kettle mouth part.

[0099] As a preferred embodiment, as Figure 4 shown, the kettle mouth part b902 includes a kettle mouth inclined surface b9021. The kettle mouth inclined surface b9021 is arranged at one end of the kettle mouth part b902 away from the water tank water outlet b8 inside the kettle mouth part b902. The width of the kettle mouth part b902 gradually decreases along the extending direction of the kettle mouth inclined surface b9021. The kettle mouth inclined surface b9021 is located at the opening end of the kettle mouth part and can play a guiding role, guiding the water or disinfected water on both sides of the opening area of the kettle mouth part b902 to flow into the kettle mouth part b902.

[0100] Regarding the structure of the kettle mouth inclined surface b9021, on the basis of the above embodiment, as a further defined embodiment, as Figure 5 shown, the kettle mouth inclined surface b9021 is provided with: a kettle mouth convex part b9022, arranged on the kettle mouth inclined surface b9021, and the kettle mouth convex part b9022 protrudes into the kettle mouth part. Since the kettle mouth inclined surface b9021 plays a guiding role, the water or disinfected water first impacts on the kettle mouth inclined surface b9021 and then flows along the inclined surface of the kettle mouth inclined surface b9021. Therefore, the kettle mouth convex part b9022 can fully impact with the water flow or disinfected water flowing along the kettle mouth inclined surface b9021. When there are undissolved salt blocks in the water or disinfected water, the salt blocks are scattered by hitting on the kettle mouth convex part b9022 and thus fully dissolved, preventing the salt blocks in the solution from entering the kettle mouth part b902 and blocking the water tank water outlet b8. On the other hand, the part adjacent to the kettle mouth part is the local structure where the water tank water inlet b7 is located. A flow meter i is arranged at the water tank water inlet b7 to monitor the water inflow of the water tank chamber. When the installation structure of the flow meter, such as a slot opening structure, etc., it can be correspondingly arranged on the back of the kettle mouth convex part. The part where the kettle mouth convex part b9022 is located is relatively thick and has good mechanical strength, which can improve the installation reliability of other components such as the flow meter. In addition to guiding the water flow, the inclined surface can also provide an installation basis for other components of the whole machine, improving the compactness of the overall mechanical structure.

[0101] Regarding the specific structure of the kettle mouth inclined surface b9021, on the basis of the above embodiment, as a further defined embodiment, as Figure 5As shown, the kettle mouth part b902 includes: a kettle mouth reinforcing rib structure, the kettle mouth reinforcing rib structure at least includes a first kettle mouth reinforcing rib b9023 and a second kettle mouth reinforcing rib b9024, and a kettle mouth channel b9025 is formed between the first kettle mouth reinforcing rib and the second kettle mouth reinforcing rib. The kettle mouth channel can further narrow the cross-sectional area through which water or disinfected water flows, and rectify the water in advance before the water or disinfected water enters the water outlet b8 of the water tank. On the other hand, the kettle mouth reinforcing rib has a certain height, and the kettle mouth reinforcing rib can be supported between the first water tank side wall and the second water tank side wall of the water tank to improve the strength of the water tank chamber.

[0102] On the basis of the above embodiments, as a further limited embodiment, as Figure 5 shown, the first kettle mouth reinforcing rib b9023 is zigzag, and a triangular reinforcing structure is formed between the first kettle mouth reinforcing rib b9023 and the kettle mouth inclined surface, so as to further improve the mechanical strength of the kettle mouth inclined surface b9021. In a preferred embodiment, as Figure 5 shown, the kettle mouth channel b9025 is provided with a kettle mouth diameter-changing part b9026 at one end close to the water outlet b8 of the water tank, and the width of the kettle mouth channel b9025 gradually increases in the direction of the water outlet b8 of the water tank at the kettle mouth diameter-changing part b9026.

[0103] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the embodiments. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the embodiments here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
