Water tank and dishwasher

Abstract

The present invention provides a water tank and dishwasher, comprising: a water tank chamber; a water channel, one end of which is connected to the water tank inlet; the water channel comprising a drainage section and a rectifying section. The drainage section and the rectifying section define a functional area, and an overflow port is provided within the functional area. The drainage section directs water from the water inlet into the water tank, while the rectifying section directs and adjusts the direction of the water flow, outputting a columnar water stream. When the water tank includes a structure such as a salt storage tank, the salt is impacted by the water column, allowing it to more fully contact and dissolve in the water. The water in the water tank is electrolyzed within the water tank or fed into an electrolysis assembly to produce disinfectant water. The pipes through which the disinfectant water flows are also disinfected and sterilized. Therefore, even if any residual disinfectant is present, bacteria will not grow. The overflow port prevents the water tank from overfilling and releases gases generated during the electrolysis process, relieving internal pressure in the water tank.

Description

Technical Field

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

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

[0003] Typically, the core components of existing dishwashers include the inner tank assembly, water cup assembly, spray arm assembly, filter assembly, wash pump, drain pump, and piping. Currently, dishwashers on the market typically use high temperatures (usually around 70°C) for both cleaning and dishware disinfection. Some also include UVC lamp disinfection, the addition of silver ions to components for antibacterial properties, steam high-temperature disinfection, and hot air drying. Summary of the Invention

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

[0005] A water tank comprising:

[0006] A water tank chamber, comprising a water tank water inlet and a water tank water outlet communicating with the water tank chamber;

[0007] A water channel, one end of which is connected to the water inlet of the water tank, the water channel includes a diversion section and a rectification section, a functional area is enclosed between the diversion section and the rectification section, and an overflow port is provided in the functional area.

[0008] The functional area is located at a relatively high position in the horizontal direction of the inner space of the water tank chamber.

[0009] A drain outlet is formed on at least one of the diversion section and the rectification section, and the drain outlet is provided on the rectification section.

[0010] The drain port extends into the water tank chamber, and the overflow port is close to the drain port and the overflow port and the drain port are arranged side by side.

[0011] The angle between the diversion section and the rectifying section is less than 180°.

[0012] The rectifying section is in an arc shape.

[0013] The water tank also includes:

[0014] The accommodating tank is arranged in the water tank chamber, and the drain port is arranged toward the open end of the accommodating tank.

[0015] The drain port is located above the accommodating tank.

[0016] The bottom and / or side wall of the accommodating tank are provided with flow holes.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. The present invention provides a water tank, comprising: a water tank chamber, comprising a water tank water inlet and a water tank water outlet connected to the water tank chamber; a water channel, one end of the water channel being connected to the water tank water inlet, the water channel comprising a diversion section and a rectification section, a functional area being enclosed between the diversion section and the rectification section, and an overflow port being provided in the functional area.

[0019] The drainage section directs water from the water inlet into the water tank, while the rectifying section directs and adjusts the direction of the water flow, producing a columnar stream. When the water tank contains a structure such as a salt storage tank, the directional impact of the water column formed by the drainage section or rectifying section allows the salt to more fully contact and dissolve in the water. When water is injected into the water tank to impact the salt to form a salt solution, or when the salt solution is injected directly through the drain, the water in the tank undergoes electrolysis within the tank or into the electrolysis component to form disinfectant water. While the disinfectant water is used to disinfect the dishes in the dishwasher, the pipes through which it flows are also disinfected and sterilized. Therefore, even if there is residual disinfectant, bacteria will not grow. The overflow port prevents the water tank from overfilling and releases gases generated during the electrolysis process, relieving internal pressure.

[0020] 2. In the water tank provided by the present invention, a drain outlet is formed on at least one of the diversion section and the rectifying section, and the drain outlet is provided on the rectifying section.

[0021] The overall shape of the flow section causes water to flow from the direction of higher gravitational potential energy to the direction of lower gravitational potential energy. This not only creates thrust for the water in the diversion section, but also converts gravitational potential energy into kinetic energy, giving the water flowing out of the flow section a stronger ability to impact the salt. When there are clumps of salt in the salt, they are more easily dispersed and dissolved in the water to form a salt solution.

[0022] 3. In the water tank provided by the present invention, the drain outlet extends into the water tank chamber, the overflow outlet is close to the drain outlet, and the overflow outlet and the drain outlet are arranged side by side.

[0023] The side wall of the drain outlet can shield the overflow outlet to prevent liquid from splashing.

[0024] 4. The water tank provided by the present invention further includes: a accommodating tank, which is arranged in the water tank chamber, and the drain outlet is arranged toward the open end of the accommodating tank.

[0025] The storage tank can store salt. When water is introduced into the water tank chamber, the salt in the storage tank contacts the water and can dissolve into the water to form a salt solution.

[0026] 5. In the water tank provided by the present invention, the drain outlet is located above the accommodating tank.

[0027] The drain port is located above the receiving tank and can output a water column toward the receiving tank, so that the salt can be more fully exposed to water and dissolved in water under the impact of the water column. Even if some salt condenses into salt blocks, it can be fully dispersed and dissolved under the impact of the water column.

[0028] 6. The water tank provided herein has flow holes formed in the bottom and / or sidewalls of the storage tank. These holes release a mixture of salt solution and salt particles at the bottom of the storage tank, alleviating the impact pressure within the storage tank and preventing the amount of water overflow from being less than the amount of water column impact input. When the storage tank accumulates a large amount of water, salt blocks can easily overflow directly through the opening at the top of the storage tank. The diversion effect of the flow holes prevents salt blocks from overflowing through the storage tank opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Example 1

[0044] This embodiment provides a dishwasher, such as Figure 1 Shown, including:

[0045] The water tank b0 is provided with a water tank chamber b901 inside, and the water tank chamber b901 is provided with a salt introduction port b10. Specifically, the salt introduction port b10 is used to add salt or brine into the water tank chamber b901. In one embodiment, the salt introduction port b10 can be used to connect the water tank chamber b901 with the brine generating device, and the brine generating device can introduce salt or brine into the water tank chamber b901 through the salt introduction port b10. When the brine generating device transports brine into the water tank chamber b901 through the salt introduction port b10, the brine can be prepared inside the brine generating device, or a pre-configured salt solution can be directly placed into the brine generating device.

[0046] Specifically, in this embodiment, an electrolysis component c0 is further provided in the water tank b0, which is arranged inside the water tank chamber b901 and is suitable for performing electrolysis operations on the brine generated by the brine generating device.

[0047] Based on the above embodiment, as a further limited embodiment, the dishwasher further includes an inner liner d5, and a water tank b0 is connected to the inner liner d5, and the water tank b0 can provide cleaning liquid to the inner liner d5. The inner liner d5 is suitable for placing tableware to be washed. The inner liner d5 itself is provided with an opening, and a door is provided on the opening, which closes the inner liner through the door. To facilitate the placement of tableware, the inner liner d5 can also be provided with several layers of bowl baskets distributed along the height direction. As an alternative embodiment, the bowl baskets can be of various specifications and can be removably installed in the inner liner d5, or they can be integrally formed in the inner liner d5.

[0048] The water tank b0 itself is typically provided with a water inlet b7 and a water outlet b8 for convenient water inlet and outlet. In this embodiment, the water inlet b7, the water outlet b8, and the salt inlet b10 form three openings on the water tank body b9. Alternatively, the salt inlet b10 and the water inlet b7 can share the same opening on the water tank body b9. In this case, water can be injected into the water tank chamber b901 through the water inlet b7, salt water can be injected into the water tank chamber b901 through the water inlet b7, and salt can also be added to the water tank chamber b901 through the water inlet b7.

[0049] There is no excessive limitation on the positional relationship between the water tank b0 and the inner tank d5. Figure 1As shown, the water tank can be directly set on the outside of the inner container. In one embodiment, the water tank b0 is set at the side wall of the inner container. In other embodiments, the water tank b0 can also be set at the top wall of the inner container. Further, the water tank b0 can also be set on the door body. As a preferred embodiment, the water tank is correspondingly set at the side wall of the inner container, that is, Figure 1 As shown, the water tank is arranged on the left side wall of the inner container. Correspondingly, the water tank can also be arranged on the right side wall of the inner container. As another alternative embodiment, the water tank b0 can also be arranged inside the inner container.

[0050] There is no specific limitation on the shape of the water tank b0. Based on the above embodiment, a further limited embodiment is provided. Figure 1 As shown, the upper portion 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 As shown in the middle perspective, that is, looking at the water tank from the left side of the inner tank d5, the water tank b0 is rectangular. As another alternative embodiment, the water tank b0 is Figure 1 The water tank b0 may be in a circular, elliptical, diamond or other irregular shape under the viewing angle. In other embodiments, the water tank b0 may be in a spherical shape.

[0051] Specifically, such as Figure 1 As shown, the width of the bottom of water tank b0 is relatively small. On the one hand, this is to facilitate the discharge of water from the water tank, that is, the water in the water tank can flow downward under its own gravity, and the smaller width of the water tank bottom can serve as a guide. On the other hand, the narrowing of the bottom can reserve more space on the side wall of the inner tank, making it easier to install other structures. For the water tank of a dishwasher, it can usually include a water softening mechanism. In this embodiment, the narrowing of the bottom of water tank b0 reserves more space for the installation of other components such as the water softener, respirator, flow meter i, etc. As an alternative embodiment, the bottom width of water tank b0 is relatively increased, or the width of water tank b0 is consistent in the height direction.

[0052] like Figure 1 As shown, the water tank b0 has a certain thickness to form an internal water tank chamber b901, and the entire water tank b0 is arranged parallel to the outer wall of the inner tank. Figure 1 It can be seen that the thickness of the water tank b0 is uniform in its thickness direction. The thickness direction of the water tank b0 can be understood as Figure 1As shown in the figure, the water tank b0 extends from the surface close to the inner pot side wall to the other surface away from the inner pot side wall d5. As an alternative embodiment, the thickness of the water tank b0 is uneven. Specifically, the side of the water tank b0 close to the inner pot d5 is parallel to the inner pot d5, and the other side is inclined toward the inner pot d5, so that the thickness of the space inside the water tank b0 gradually changes along the height direction of the water tank b0, thereby forming a water tank chamber b901 with varying thickness. The shape and thickness of the water tank chamber b901 are changed, on the one hand, to facilitate the installation and function of the internal components; on the other hand, to form a structural coordination between the installation and connection of the water tank b0 and other mechanisms of the dishwasher, thereby saving space and increasing the compactness of the internal structure.

[0053] Furthermore, the water tank chamber b901 within water tank b0 is used to store and prepare cleaning fluid. The cleaning fluid used in dishwashers can be water, salt water, detergent for decontamination and degreasing, disinfectant, etc. The cleaning fluid is typically transported to the point of use via a pipeline structure, and different cleaning modes may correspond to different cleaning fluid temperatures. Therefore, if the cleaning fluid within water tank b0 needs to be heated, the outer shell of water tank b0 can be provided with recessed structures and / or raised structures, allowing the pipeline structure to pass through the recessed structures and / or raised structures. When the cleaning fluid within water tank b0 is heated, the medium within the pipeline structure can be supplementally heated to save energy.

[0054] In this embodiment, the water tank b0 includes a water tank body b9 and other components arranged in the water tank body b9. The water tank body b9 can be understood as the shell structure of the water tank b0. Figure 1 、 Figure 5 As 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, and the first water tank side wall b904 and the second water tank side wall b905 are both protruded with a stop structure that adapts to each other, as shown in FIG. Figure 5 As shown, the second water tank sidewall b905 snaps onto the first water tank sidewall b904, thereby forming a relatively enclosed water tank chamber b901 within the water tank body b9. As an alternative embodiment of the structure of the water tank body b9, the water tank body b9 can be composed of three or more components. As another alternative embodiment of the structure of the water tank body b9, the outer shell of the water tank body b9 is an integrally formed unit.

[0055] The cleaning liquid inside the dishwasher of this embodiment includes disinfectant water, and the preparation principle of disinfectant water is as follows: cathode: 2Cl--2e=Cl2

[0056] Anode: 2H2O+2e-=H2+2OH-

[0057] Overall reaction: 2Cl-+2H2O=H2+Cl2+2OH-

[0058] A disproportionation reaction will occur between chlorine and water: Cl2+H2O=HCl+HClO. The produced HClO itself has certain oxidizing properties, thereby achieving the killing effect on bacteria and viruses.

[0059] In this embodiment, the salt used is mainly composed of NaCl, which is non-toxic and stable, not easily deteriorated, and convenient for storage and electrolytic disinfection. Other chlorates, such as KCl and CaCl, are not recommended because they can cause certain harm to the human body.

[0060] On the basis of the above embodiment, as a further limited embodiment, the salt water generating device is arranged inside the water tank b0, and the salt water generating device can provide salt water, or provide raw materials for preparing salt water, so as to support the preparation and transportation of salt water. At this time, the user can add salt or salt water to the salt water generating device through the salt delivery port b10. On the basis that the salt delivery port b10 is connected to the salt water generating device, the salt water generating device can be directly arranged on the salt delivery port b10, and can also be arranged downstream of the salt delivery port b10 to receive the salt or salt water delivered through the salt delivery port b10. As an alternative embodiment, the salt water generating device can also be arranged outside the water tank, and the salt water generating device can be connected to the water tank b0 through a pipeline structure. As another alternative embodiment, the salt water generating device is arranged on the outer wall of the water tank, and is connected to the interior of the water tank through structures such as a stopper.

[0061] There is no limitation on the specific structure of the salt water generating device. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the salt water generating device in this embodiment is a salt dispenser. The salt dispenser can dispense salt or brine into the water tank chamber b901 through the salt inlet b10. In this embodiment, the salt dispenser specifically comprises a receiving tank a1, which is positioned above the salt inlet b10 and capable of accommodating salt. After the water tank is filled with water, the water and salt come into contact, dissolving the salt in the water tank chamber b901 to form brine, which is then used by the electrolysis component c0 to prepare disinfectant water. Alternatively, the salt dispenser can be a pipe structure, with one end connected to the water tank b0 and the other end extending to the outside of the dishwasher, allowing the user to dispense salt into the water tank b0 from outside the dishwasher.

[0062] There is no specific limitation on the location of the receiving tank a1. Based on the receiving tank a1 being located inside the water tank b0, as a further limited embodiment, Figure 1As 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.

[0063] In order to facilitate the replenishment of salt into the containing tank a1, based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the receiving tank a1 is detachably connected to the water tank body b9, allowing the user to remove the receiving tank a1 from the water tank b0 and add salt to the receiving tank a1 from outside the dishwasher. Because the first water tank sidewall b904 of the water tank b0 is adjacent to the outer wall of the inner liner d5, an opening is formed through the water tank sidewall and the inner liner d5 to facilitate the passage of the receiving tank a1. The opening forms a salt injection port b10 on the first water tank sidewall b904. A sealing structure is provided between the water tank, the inner liner, and the receiving tank a1 to ensure that the receiving tank a1 enters the water tank from within the inner liner d5, sequentially through the sidewall of the inner liner d5 and the first water tank sidewall b904. When the salt water generator is used to provide salt water, salt water can be directly introduced into the water tank chamber b901 through the salt injection port b10. As an alternative embodiment, the receiving tank a1 can also be located on the second water tank sidewall b905. The dishwasher housing is provided with a passage or opening for the accommodating tank a1, allowing the user to conveniently install the accommodating tank on the water tank body b9 from the outside of the dishwasher, thereby replenishing salt into the water tank chamber b901. Alternatively, the accommodating tank may be located on another sidewall of the water tank chamber b901.

[0064] In order to facilitate the dissolution efficiency of salt and water, the container a1 can be rotated and clamped with the water tank body b9. After the user adds salt to the container a1, the container a1 is inserted into the water tank chamber b901 with the opening facing upwards. When it is plugged into the rotation position, it is rotated and clamped. Figure 2 、 Figure 3 At this point, the upward-opening tank is tilted or facing downward, spreading the salt pile's surface area. When the tilt angle is relatively large, some salt will fall directly into water tank chamber b901. When the opening of tank a1 is completely downward, the majority of the salt falls into water tank chamber b901. When water fills water tank chamber b901 through water inlet b7, water gradually accumulates within the tank. The flowing water comes into contact with the salt that has fallen into water tank chamber b901, dissolving the salt.

[0065] There is no specific limitation on the location of the receiving groove a1. Based on the above embodiment, as a further limited embodiment, Figure 1As shown, the accommodating tank a1 is disposed in the upper half of the water tank chamber b901. As an alternative embodiment, the accommodating tank a1 is disposed in the lower half of the water tank chamber b901, and the accommodating tank a1 can be disposed close to the inner wall of the water tank chamber b901. Furthermore, the accommodating tank a1 can share the same sidewall structure with the water tank chamber b901.

[0066] In this embodiment, the water tank inlet b7 is used to fill the water tank b0, and the water tank outlet b8 is connected to the inner container d5. This embodiment also includes a water cup, which is used to supply water to the inner container d5. The water tank outlet b8 is used to supply water to the cup, and the water tank outlet b8 is connected to the cup via a piping structure. To meet the temperature requirements of various washing modes, a heating device can be installed in the water tank b0, in the cup, or on the piping structure between the water tank and the cup.

[0067] There is no specific limitation on the location of the water outlet b8 of the water tank. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the water tank outlet b8 is located at the bottom of the water tank. This arrangement allows the water in the water tank chamber b901 to drain automatically by gravity after the valve is opened, even without installing a pump. This drain is achieved through the drain pipe d42 connected to the water tank outlet b8. Alternatively, the water tank outlet b8 can be located anywhere on the inner wall of the water tank chamber b901, allowing drainage to be achieved through the drain pipe d42 in conjunction with the pump structure.

[0068] There is no specific limitation on the location of the water tank inlet b7. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the water tank inlet b7 is located at the bottom of the water tank chamber b901. Specifically, the water tank inlet b7 is located adjacent to the water tank outlet b8. Because both the water tank inlet b7 and the water tank outlet b8 require connection to a piping structure, their adjacent placement facilitates uniformly reserving space and installing piping structures at corresponding locations within the dishwasher. As an alternative embodiment, the water tank inlet b7 can be located anywhere on the inner wall of the water tank chamber b901.

[0069] On the basis of the above embodiment, as a further limited embodiment, Figure 1 As shown, since the water tank chamber b901 has a accommodating tank a1, and the accommodating tank a1 has salt to be dissolved, in order to improve the dissolution efficiency of the salt, a water channel b5 is set in the water tank b0. Figure 2 、 Figure 3 As shown, a drain outlet b501 is formed on the water channel b5, and the opening of the drain outlet b501 is set toward the opening of the accommodating groove a1. Figure 1As shown, when water is being filled in tank b0, water is introduced into waterway b5 through tank inlet b7 and then discharged through outlet b501, directly into tank a1. Therefore, during the filling process, tank a1 is constantly flushed, ensuring that the salt is in full contact with the flowing water, thereby accelerating salt dissolution. Furthermore, any salt in tank a1 that has partially clumped into salt can be broken down by the direct impact of the water flow, further accelerating salt dissolution.

[0070] In the above-described embodiment, the water channel b5 may be formed with multiple drain outlets b501. The drain outlets b501 may be open or equipped with valves to switch between opening and closing. The multiple drain outlets b501 may have the same or different inner diameters. Drain outlets with different inner diameters can generate water jets of varying strengths, allowing users to switch between them.

[0071] There is no specific limitation on the shape of the drain outlet b501. In this embodiment, Figure 2 、 Figure 3 As shown, the inner wall of the drain outlet is straight, forming a linear waterway. This can reduce the friction experienced by water flowing along the inner wall of the drain outlet. As the water flows through drain outlet b501, it can continue to be pushed by the subsequent water flow in the waterway, thereby accelerating the water within drain outlet b501 and increasing the impact force of the water flowing out of the drain outlet. As an alternative embodiment, drain outlet b501 is parabolic or arc-shaped, and the inner wall of the drain outlet is smooth. As another alternative embodiment, drain outlet b501 is in the shape of a broken line.

[0072] There is no specific limitation on the shape of the water channel b5. In this embodiment, Figure 1As shown, water channel b5 includes a diversion section b502 and a flow-regulating section b503. The drain outlet b501 is formed on at least one of the diversion section b502 and the flow-regulating section. The diversion section b502 directs water from the water inlet into the water tank chamber b901, while the flow-regulating section b503 directs and adjusts the direction of the water flow, thereby outputting a columnar stream. If the water tank b0 includes a salt storage tank or other structure, the directional impact of the water column formed by the diversion section b502 or the flow-regulating section allows the salt to more fully contact and dissolve in the water. Alternatively, the water tank b0 lacks the storage tank a1. Instead, salt can be directly sprayed into the water tank chamber b901 through the salt inlet b10, where it accumulates at the bottom of the chamber. The drain outlet b501 then sprays water toward the accumulated salt, causing it to dissolve in contact with the water. The impact of the water column causes the water flow to surge locally, accelerating the dissolution of the salt. When water is injected into the water tank b0 to form a salt solution, or when a salt solution is injected directly through the drain port b501, the water in the water tank undergoes electrolysis within the tank or into the electrolysis module to form disinfectant water. While the disinfectant water disinfects the dishes in the dishwasher, the pipes through which it flows are also sterilized. Therefore, even in the presence of disinfectant, bacteria will not grow.

[0073] On the basis of the above embodiment, as a further limited embodiment, Figure 1 As shown, the drain outlet is provided on the rectifying section b503. The overall shape of the rectifying section b503 causes water to flow from the direction of higher gravitational potential energy to the direction of lower gravitational potential energy. On the one hand, the water in the drainage section forms a thrust on the water in the rectifying section b503. On the other hand, the gravitational potential energy is converted into kinetic energy, so that the water flowing out of the rectifying section b503 has a stronger ability to impact the salt. When there are condensed salt blocks in the salt, they can be more easily dispersed and dissolved in the water to form a salt solution. As an alternative embodiment, the drain outlet is provided on the drainage section b502. As another alternative embodiment, when there are multiple drain outlets, they can be distributed respectively on the drainage section b502 and the rectifying section b503.

[0074] There is no specific limitation on the positional relationship between the diversion section b502 and the rectification section b503. Based on the above embodiment, as a further limited embodiment, Figure 1-Figure 3 As shown, the angle between the diversion section b502 and the straightening section b503 is less than 180°, and the diversion section b502 and the straightening section b503 enclose a functional area b903. As an alternative embodiment, the angle between the diversion section b502 and the straightening section b503 is equal to 180°, or greater than 180°.

[0075] There is no specific limitation on the shape of the rectifying section b503. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the rectifying section b503 is arc-shaped. As an alternative embodiment, Figure 2 As shown, the flow section b503 is a straight line or a broken line. The broken line shape can refer to an "M" shape, an "N" shape, a "V" shape, etc., which will not be described in detail in this embodiment. Those skilled in the art can change the shape of the flow section b503 based on the above examples to optimize the water path and improve the water injection efficiency and salt dissolution efficiency. As another alternative embodiment, the flow section b503 is a wave shape.

[0076] Specifically, the functional area b903 is located at a relatively high level within the water tank chamber b901. An overflow port b6 is provided within the functional area b903. When the water level inside the water tank is excessive, the excess water can be drained out through the overflow port b6. The overflow port b6 also detects the water level inside the water tank and controls the water inlet b7 to stop the water inlet. The functional area is positioned relatively high above the water tank chamber b901 to allow for a certain amount of space at the top of the water tank, provided that the water, salt water, and disinfectant can be accommodated within the water tank chamber b901. Once the water, salt water, and disinfectant levels reach the designated capacity, they are positioned below the functional area, allowing the overflow port to fully function as a drain and vent. When electrolysis occurs within the water tank, flammable gases such as hydrogen are generated. The overflow port b6 allows the hydrogen to be quickly drained from the interior of the water tank to the outside, ensuring the tank's safety. For the dishwasher itself, an exhaust structure can be set inside the dishwasher to cooperate with the overflow port to complete the exhaust function.

[0077] Furthermore, in this embodiment, Figure 2 、 Figure 3 As shown, the drain outlet b501 and the overflow outlet b6 are arranged side by side, and the drain outlet b501 can play a role in differentiating the functional area b903 in the water tank chamber b901. The overflow outlet b6 is adjacent to the side wall of the drain outlet b501 and is arranged side by side with the drain outlet b501, so that the horizontal height of the overflow outlet is not lower than the height of the water outlet of the drain outlet b501, thereby preventing the water discharged from the drain outlet b501 from overflowing through the overflow outlet b6.

[0078] Because salt takes time to dissolve, some of the salt carried out of the tank by the water flow forms salt clumps. Salt clumps dissolve more slowly than smaller salt particles, causing them to easily settle at the bottom of the tank. Because the water outlet b8 is located at the bottom of the tank chamber b901, salt clumps can easily accumulate there, causing blockage.

[0079] On the basis of the above embodiment, a rectifying structure is further provided in the water tank b0, such as Figure 1-Figure 3 As shown, a rectifying structure is provided on the inner wall of the water tank chamber b901, specifically the first water tank sidewall b904 in this embodiment. The rectifying structure includes at least one rib located in the salt flow path and upstream of the water tank outlet. Water flow detours around the rectifying structure, forming at least one bypass path. When salt is added to the water tank chamber b901 through the salt inlet b10, the ribs of the rectifying structure form a salt supply and water bypass path. This structure intercepts salt clumps on their way to the outlet, causing them to impact and disperse, or delaying their arrival. The impact and dispersion of salt clumps increases the contact area between the salt clumps and the solution, accelerating their dissolution. This increased time for salt clumps to reach the outlet increases the salt's time in the solution, allowing them to dissolve more fully before reaching the outlet, further resolving the issue of salt clumps easily clogging the outlet.

[0080] Specifically, such as Figure 1 As shown, the rectifying structure includes: a first rib b1, which is arranged near the water outlet b8 of the water tank. The first rib b1 is arranged near the water outlet b8 of the water tank, which can intercept and disperse the salt blocks flowing towards the water outlet and force the salt blocks to bypass and fully dissolve.

[0081] There is no specific limitation on the arrangement of the first rib b1. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the first rib b1 is arranged horizontally. As an alternative embodiment, the first rib b1 is arranged obliquely.

[0082] On the basis of the above embodiment, as a further limited embodiment, Figure 1 As shown, the rectifying structure further includes a second rib b2, positioned between the downstream portion of the salt inlet b10 and the upstream portion of the first rib b1. The second rib b2 can disperse and intercept salt clumps before they reach the first rib b1. As the salt clumps bypass the second rib b2, they can more fully come into contact with the solution and dissolve, further enhancing the rectifying structure's ability to intercept and disperse salt clumps and promote dissolution.

[0083] There is no specific limitation on the number of the second ribs b2. Based on the above embodiment, as a further limited embodiment, Figure 1As shown, there are two second ribs b2, with a spacing between them. This spacing 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 baffle channel while also temporarily intercepting larger salt blocks at the opening of the baffle channel. When a salt block is stuck at the opening of the baffle channel, as water flows in or the salt solution flows out, the solution in the water tank chamber remains in a fluid state, and the impact of the water flow accelerates the dissolution or fragmentation of the salt block.

[0084] There is no specific limitation on the position relationship of the second rib b2. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, at least one of the second ribs b2 is tilted toward the salt inlet. When salt is added through the salt inlet, because the second rib b2 is positioned toward the salt inlet b10, the salt will impact the second rib b2 as it falls within the water tank chamber b901, easily dispersing the salt and preventing it from forming lumps. When salt solution is injected through the salt inlet b10, it falls onto the second rib b2. The second rib b2 provides a diversion and buffering function, preventing the salt solution from directly falling to the bottom of the water tank chamber b901 and causing impact and splashing within the water tank.

[0085] There is no specific limitation on the positional relationship between the second rib b2 and the first rib b1. Based on the above embodiment, as a further limited embodiment, Figure 1 As shown, the second rib b2 at least partially covers the gap upstream between the first rib b1 and the inner wall of the water tank chamber. The second rib b2, at least partially located above the first rib b1, can provide a layered barrier to the falling salt blocks, or the salt blocks falling with the flow of water, further enhancing the rectifier's ability to block the salt blocks and accelerate their dissolution. Furthermore, this layered barrier arrangement can continuously promote the formation of deflections in the direction of the water flow, thereby creating localized turbulence within the water body and further promoting the dissolution of the salt blocks.

[0086] There is no specific limitation on the structure of the ribs in the rectification structure, such as the first rib b1 and the second rib b2. On the basis of the above embodiment, as a further limited embodiment, the ribs are provided with a plurality of protrusion structures. The protrusion structure can increase the pressure on the salt block when it touches the protrusion during the contact with the salt block, thereby promoting the crushing and decomposition of the salt block. At the same time, the protrusion can intercept the salt block, so that the salt block is intercepted in the gap between the protrusions. As an alternative embodiment, the ribs are a strip array structure composed of multiple columnar units. There is a gap between adjacent columnar units to intercept the salt blocks. As another alternative embodiment, the ribs are a mesh structure.

[0087] On the basis of the above embodiment, as a further limited embodiment, the first rib b1 and the second rib b2 can extend from the first water tank side wall b904 to the second water tank side wall b905, so that after the second water tank side wall b905 is installed in conjunction with the first water tank side wall b904, the first rib b1 and the second rib b2 support the first water tank side wall b904 and the second water tank side wall b905, thereby improving the strength of the water tank body b9.

[0088] In this embodiment, to ensure sufficient dissolution of the salt in tank a1, several flow holes a103 are provided at the bottom of tank a1. These holes ensure that the solution produced in tank a1 can flow out completely, preventing residual liquid from remaining in the tank and causing the subsequent disinfectant concentration to substandard.

[0089] The number, arrangement, and shape of the flow holes themselves are not particularly limited. Other arrangements, such as an annular or triangular arrangement, may be employed. As a preferred embodiment, several flow holes a103 are arranged in a straight line at the bottom of the receiving tank a1. Furthermore, the flow holes themselves can be regular, such as rectangular or elliptical, or irregular, as long as leakage can be achieved. As a preferred embodiment, the flow holes themselves are circular. Furthermore, the diameter of the circular holes ranges from 0.5 mm to 5 mm. This sizing prevents salt particles from escaping the receiving tank directly through the flow holes.

[0090] As a preferred embodiment, in this embodiment, Figure 3 As shown, the projection of the drain port 501 coincides with the flow hole a103. Specifically, the drain port 501 is positioned directly above the flow hole. This arrangement allows water flowing out of the drain port b501 to be directly applied to the flow hole a103. At this point, the water has greater kinetic energy due to its weight, so after flushing the salt, the brine can be discharged directly from the flow hole a103, thereby improving the efficiency of brine preparation.

[0091] In order to facilitate the drainage function of the water tank b0 and prevent the water outlet from being blocked, Figure 1 、 Figure 4 As shown, there is a pot mouth portion b902 with a gradually narrowing width at the bottom of the water tank.

[0092] There is no specific restriction on the location of the pot mouth b902. Figure 4As shown, in this embodiment, the mouth of the pot b902 is correspondingly arranged below the salt delivery port b10 and / or the salt dispenser. When water, electrolyte solution, or disinfectant is directly injected into the water tank chamber through the salt delivery port, the water flow will not directly impact the mouth of the pot, but will be buffered by the first rib to prevent the formation of foam during water injection. The first rib b1 can be arranged near the opening of the mouth of the pot or inside the mouth of the pot. There can be multiple first ribs, and the multiple first ribs are distributed in the mouth of the pot and on the part of the water tank chamber b901 near the opening of the mouth of the pot.

[0093] As a preferred embodiment, Figure 4 As shown, the mouth portion b902 includes a bevel b9021, which is located at one end of the mouth portion b902 away from the water tank outlet b8. The width of the mouth portion b902 gradually decreases as the bevel b9021 extends. The bevel b9021 is located at the opening end of the mouth portion and can serve as a guide, directing water or disinfectant on both sides of the opening area of ​​the mouth portion b902 to flow into the mouth portion b902.

[0094] Regarding the structure of the Hukou slope b9021, based on the above embodiment, as a further limited embodiment, Figure 5 As shown, the Hukou inclined surface b9021 is provided with a Hukou convex portion b9022, which is disposed on the Hukou inclined surface b9021 and projects inwardly from the Hukou portion. Because the Hukou inclined surface b9021 serves as a guide, water or disinfectant first impacts the Hukou inclined surface b9021 before flowing along the inclined surface of the Hukou inclined surface b9021. Therefore, the Hukou convex portion b9022 can fully collide with the water or disinfectant flowing along the Hukou inclined surface b9021. If undissolved salt lumps remain in the water or disinfectant, the salt lumps will be dissipated by the impact of the water flow on the Hukou convex portion b9022, thereby being fully dissolved. This prevents the salt lumps from entering the Hukou portion b902 and clogging the water tank outlet b8. On the other hand, adjacent to the pot mouth is the local structure where the water tank inlet b7 is located. A flow meter i is installed at this inlet to monitor the water flow into the tank chamber. The flow meter's mounting structure, such as a trough, can be located on the back of the pot mouth protrusion. The area where the pot mouth protrusion b9022 is located is relatively thick, providing good mechanical strength and enhancing the installation reliability of other components, such as the flow meter. In addition to guiding the flow of water, the inclined surface also provides a mounting base for other components of the entire machine, improving the compactness of the overall mechanical structure.

[0095] Regarding the specific structure of the Hukou slope b9021, based on the above embodiment, as a further limited embodiment, Figure 5As shown, the mouth portion b902 includes a mouth reinforcement rib structure, comprising at least a first mouth reinforcement rib b9023 and a second mouth reinforcement rib b9024. A mouth channel b9025 is formed between the first and second mouth reinforcement ribs. The mouth channel further reduces the cross-sectional area through which water or disinfectant flows, streamlining the flow before it enters the water tank outlet b8. Furthermore, the mouth reinforcement ribs have a certain height, allowing them to be supported between the first and second sidewalls of the water tank, thereby increasing the strength of the water tank chamber.

[0096] On the basis of the above embodiment, as a further limited embodiment, Figure 5 As shown, the first Hukou reinforcement rib b9023 is in a broken line shape, and a triangular reinforcement structure is formed between the first Hukou reinforcement rib b9023 and the Hukou inclined surface, thereby further improving the mechanical strength of the Hukou inclined surface b9021. Figure 5 As shown, the Hukou channel b9025 is provided with a Hukou reducing portion b9026 at one end close to the water tank outlet b8, and the width of the Hukou channel b9025 gradually increases at the Hukou reducing portion b9026 toward the water tank outlet b8.

[0097] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
