[0045] The present application discloses a water tank 1000 , which will be described in detail below in conjunction with a dishwasher.

[0046] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present application, the water tank 1000 includes a first cavity 1100 and a ventilation flow channel 1500, the first cavity 1100 is provided with an inner tank interface 1600, the first cavity 1100 is connected to the inner tank of the dishwasher through the inner tank interface 1600, water above the preset water level of the first cavity 1100 can flow out of the first cavity 1100 through the inner tank interface 1600, and then flow into the inner tank of the dishwasher, the ventilation flow channel 1500 is connected with the outside and the first cavity 1100 to achieve air pressure balance, at least a portion of the ventilation flow channel 1500 passes over the inner tank interface 1600 and extends to both sides of the inner tank interface 1600, the ventilation flow channel 1500 includes a first air port 1511, the first air port 1511 is provided on one side of the inner tank interface 1600, and is connected to the first cavity 1100. By providing the inner tank interface 1600, during the process of injecting water into the first cavity 1100, water can be injected into the inner tank of the dishwasher through the inner tank interface 1600, thereby achieving water inflow into the inner tank of the dishwasher. At the same time, the first cavity 1100 can store a certain amount of water, thereby absorbing the heat emitted when the dishwasher is working, thereby saving energy consumption. By providing the ventilation flow channel 1500, at least a part of the ventilation flow channel 1500 passes over the inner tank interface 1600 and extends to both sides of the inner tank interface 1600, thereby preventing the water in the first cavity 1100 from overflowing to the outside through the ventilation flow channel 1500 when the water tank 1000 is tipped over. The water in the first cavity 1100 can only be injected into the inner tank of the dishwasher through the inner tank interface 1600, thereby avoiding water overflow and soaking the surrounding environment of the dishwasher, thereby enabling the water tank 1000 to achieve a tipping anti-overflow function.

[0047] Specifically, the dishwasher has an inner tank, in which a bowl basket and a spray arm are arranged. The bowl basket can be used to load tableware, and the spray arm is used to spray water to wash the tableware. The dishwasher has a washing pump, the inlet of the washing pump is connected to the inner tank, and the outlet of the washing pump is connected to the spray arm. When the dishwasher is working, a certain amount of water will be injected into the inner tank, and the washing pump will suck the water in the inner tank and transport it to the spray arm. The spray arm sprays water to wash the tableware, and the water sprayed by the spray arm will fall back into the inner tank and continue to be sucked by the washing pump, thus forming a cycle. In order to improve the washing effect of the tableware, the water in the inner tank will be heated. For example, the washing pump is integrated with a heating element, and the water will be heated synchronously during the process of the washing pump sucking water. Generally speaking, the inner tank is made of metal sheet metal or plastic. Even if it is not made of metal sheet metal or plastic, it is difficult for the inner tank to form heat insulation, so it will dissipate heat to the outside. In this embodiment, a water tank 1000 is provided to absorb the dissipated heat to save energy.

[0048] The water tank 1000 will be installed on the inner tank and set close to the inner tank. The first cavity 1100 will temporarily store a certain amount of water. During the operation of the dishwasher, the heat emitted will be absorbed by the water in the first cavity 1100 to avoid heat loss, thereby keeping the inner tank warm. The water in the first cavity 1100 is also used to supply the inner tank to provide washing water. Since the water in the water tank 1000 absorbs the heat emitted by the inner tank, it has a higher temperature than municipal water. Therefore, if the water in the first cavity 1100 is input into the inner tank, the amount of electricity required for heating during the washing process will be reduced compared to heating only municipal water, thereby reducing energy consumption.

[0049] For example, when the dishwasher is washing (assuming that the dishwasher is used for the first time), it generally has multiple washing cycles. In the first washing cycle, the first cavity 1100 is first filled with water, and the water is also introduced into the inner tank. During this washing cycle, the water in the inner tank will be heated, and the heat emitted by the inner tank will be absorbed by the water in the first cavity 1100. When entering the second washing cycle, the water in the first cavity 1100 can be introduced into the inner tank, and then the water in the first cavity 1100 is replenished. It can be understood that if the water in the first cavity 1100 is not enough to carry out the washing cycle after being introduced into the inner tank, it is necessary to continue to introduce municipal water into the inner tank. Since the water in the first cavity 1100 has absorbed the heat emitted by the inner tank during the first washing cycle, the power consumed for heating the water in the inner tank during the second washing cycle will be reduced. In addition, after the dishwasher finishes washing the dishes, the first cavity 1100 may also be filled with water, which will absorb ambient heat. When the dishwasher is used next time, the temperature of the water in the first cavity 1100 will also be higher than municipal water, which can also reduce energy consumption.

[0050] The first cavity 1100 has an inner tank interface 1600, which is in communication with the first cavity 1100. The inner tank interface 1600 is connected to the inner tank of the dishwasher. The inner tank of the dishwasher is provided with a corresponding opening, and the inner tank interface 1600 is connected to the opening on the inner tank, so that the first cavity 1100 and the inner tank of the dishwasher are connected. In the process of filling water into the first cavity 1100, the water level in the first cavity 1100 gradually rises until the water level in the first cavity 1100 reaches a preset height (preset water level). When the water level continues to rise, the water in the first cavity 1100 that is higher than the preset water level flows into the inner tank of the dishwasher through the inner tank interface 1600 until the water level in the inner tank reaches the preset height, thereby stopping water inflow. At this time, the inner tank has circulating washing water, and the first cavity 1100 of the water tank 1000 stores corresponding water.

[0051] Before the first cavity 1100 is filled with water, the first cavity 1100 contains air. If the air is not exhausted, it will be difficult to inject water into the first cavity 1100. Therefore, by setting up the ventilation flow channel 1500, the ventilation flow channel 1500 is connected with the outside world and the first cavity 1100, so as to maintain the internal and external air pressure balance of the water tank 1000. The outside world here refers to the external atmosphere. For example, a first air port 1511 is formed at one end of the ventilation flow channel 1500, and the first air port 1511 is connected with the first cavity 1100. It can be understood that since the first air port 1511 needs to connect the first cavity 1100 with the outside world, it means that the first air port 1511 needs to be designed to be higher than the inner tank interface 1600 or the preset water level (with the normal placement of the water tank 1000 as a reference), and a second air port 1521 is formed at the other end of the ventilation flow channel 1500, and the second air port 1521 is connected with the outside world. Since the inner tank interface 1600 is respectively connected with the first cavity 1100 and the inner tank, the inner tank is connected with the outside world. When water is injected into the first cavity 1100, the air in the first cavity 1100 can be discharged to the outside through the first air port 1511 and the ventilation channel 1500, and then discharged to the outside through the second air port 1521. Since the dishwasher needs to heat water during operation, a certain amount of water vapor will be formed in the inner tank, and the air pressure in the inner tank is relatively high. Since the inner tank is connected to the outside through the ventilation channel 1500, the air pressure in the inner tank and the outside can be balanced, ensuring normal washing.

[0052] Since the ventilation channel 1500 is provided to connect the first cavity 1100 with the outside, when the water tank 1000 is tilted with the dishwasher, the water in the first cavity 1100 is easy to overflow to the outside through the ventilation channel 1500 and wet the installation environment of the dishwasher. Therefore, the provision of the ventilation channel 1500 is particularly important. In this embodiment, the following provision is made to avoid the overflow of water in the first cavity 1100. At least part of the ventilation channel 1500 passes over the inner tank interface 1600 and extends to the opposite sides of the inner tank interface 1600. It should be noted that the opposite sides here are specifically, combined with Figure 2 In the orientation shown, a vertical line is drawn through the approximate center of the inner tank interface 1600, and the front and rear sides of the vertical line are the opposite sides of the inner tank interface 1600. At least part of the ventilation channel 1500 extends from the front side (one side) to the rear side (the other side). It can be understood that one side can also be regarded as the rear side and the other side can be regarded as the front side. For example, at least part of the ventilation channel 1500 is located above the inner tank interface 1600 and extends to the rear and front sides of the inner tank interface 1600. The first air port 1511 is located at the front side of the inner tank interface 1600. In this way, when water is stored in the first cavity 1100 and the dishwasher is overturned, a large amount of water can be prevented from overflowing to the outside through the ventilation channel 1500.

[0053] Take the example of a dishwasher tipping forward. Figure 2 In the orientation shown, when the water tank 1000 is in a state of tilting forward with the dishwasher, the inner tank interface 1600 is at a higher position relative to the first air port 1511, and the water in the water tank 1000 will flow into the inner tank through the inner tank interface 1600. At the same time, the water will also enter the ventilation flow channel 1500 through the first air port 1511 until the water level in the ventilation flow channel 1500 is equal to the water level in the first cavity 1100. In this process, a large amount of water in the first cavity 1100 has entered the inner tank of the dishwasher through the inner tank interface 1600, so only a small amount of water enters the ventilation flow channel 1500. In particular, the inner tank interface 1600 is usually designed to be larger than the first air port 1511, and the water entering the ventilation flow channel 1500 will be less. Since at least part of the ventilation channel 1500 extends to opposite sides of the inner tank, the part of the ventilation channel 1500 located at the rear side of the inner tank interface 1600 is higher than the inner tank interface 1600 in this state, and even if water enters the ventilation channel 1500, it will not quickly overflow to the outside. During the process of resetting the dishwasher, the ventilation channel 1500 is inclined at a certain stage, so that the water entering the ventilation channel 1500 can fall back to the first cavity 1100 under the action of gravity, preventing the water entering the ventilation channel 1500 from being discharged to the outside after the dishwasher is reset.

[0054] Take the example of a dishwasher tipping over backwards. Figure 2In the position shown, the water tank 1000 is in a state of following the dishwasher to tilt backwards, at which time the first air port 1511 is at a higher position relative to the inner tank interface 1600, and the water in the water tank 1000 will flow into the inner tank through the inner tank interface 1600 until the water level in the first cavity 1100 is lower than the inner tank interface 1600. During this tilting process, the water in the first cavity 1100 has already quickly entered the inner tank through the inner tank interface 1600, so that the water in the first cavity 1100 is lower than the first air port 1511, thus preventing water from entering the ventilation flow channel 1500. In particular, the inner tank interface 1600 is usually designed to be larger than the first air port 1511, and at this time, it is difficult for the water in the first cavity 1100 to enter the ventilation flow channel 1500 through the first air port 1511 during the process of the water tank 1000 tilting backwards.

[0055] In some embodiments of the present application, the ventilation flow channel 1500 includes a second flow segment 1520 and a first flow segment 1510, the second flow segment 1520 is connected to the first flow segment 1510, and the first flow segment 1510 is arranged on one side (front side) of the inner liner interface 1600, and the second flow segment 1520 extends from the first flow segment 1510 to the other side (rear side) of the inner liner interface 1600, the second flow segment 1520 is connected to the first flow segment 1510, and a part of the second flow segment 1520 and the first flow segment 1510 form a U-shaped flow channel 1530, and the first air port 1511 is arranged in the first flow segment 1510 and is open to the other side (rear side).

[0056] Specifically, since the second flow segment 1520 and the first flow segment 1510 form a U-shaped flow channel 1530 , that is, the flow channel wall of the first flow segment 1510 will block the sloshing water, thereby preventing the water from directly rushing into the ventilation flow channel 1500 . For example, when the water tank 1000 is in the process of following the dishwasher to tip backwards, if the water tank 1000 is tipped backwards at a fast speed, the water in the first cavity 1100 will shake quickly, and the water may overflow to the outside through the first air port 1511 before it has time to flow into the inner tank through the inner tank interface 1600. By setting the structure of the U-shaped flow channel 1530, the U-shaped flow channel 1530 is in a downward inverted U-shape during the tipping process, and the water in the first cavity 1100 will impact the flow channel wall of the first flow segment 1510. The flow direction of this part of the water roughly intersects with the first flow segment 1510 and is blocked by the first flow segment 1510. In this way, when the water tank 1000 is tipped backwards quickly, the water in the first cavity 1100 can be prevented from entering the ventilation flow channel 1500.

[0057] Assuming that a small amount of water enters the ventilation channel 1500 under certain circumstances, in order to prompt this part of water to flow back to the first cavity 1100 more quickly, combined with Figure 2 and Figure 3As shown, at least part of the second flow segment 1520 is arranged to be inclined downward. Taking the ventilation flow channel 1500 including the first flow segment 1510 and the second flow segment 1520 as an example, the second flow segment 1520 is inclined upward from the first flow segment 1510 (from another angle, it is inclined downward). When the dishwasher is tilted forward, the water in the first cavity 1100 flows into the inner tank through the inner tank interface 1600 until the water level is lower than the inner tank interface 1600. At this time, a part of the water enters the first flow segment 1510 and the second flow segment 1520. When the water tank 1000 is straightened (reset), the water in the second flow segment 1520 and the first flow segment 1510 can quickly flow out of the ventilation flow channel 1500 through the first air port 1511 under the action of the inclined part of the second flow segment 1520, and then flow back to the first cavity 1100 or the inner tank.

[0058] Furthermore, combined with Figure 2 As shown, in some embodiments of the present application, at least a portion of the second flow segment 1520 may also be designed to be arched upward, so that the water in the second flow segment 1520 can be prevented from being discharged to the outside. When the dishwasher is tilted forward, the water in the first cavity 1100 flows into the inner tank through the inner tank interface 1600 until the water level is lower than the inner tank interface 1600. At this time, a portion of the water enters the first flow segment 1510 and the second flow segment 1520. When the water tank 1000 is straightened, the water in the second flow segment 1520 may not have time to flow back to the first cavity 1100 due to the rapid straightening of the water tank 1000. By arching at least a portion of the second flow segment 1520, the aforementioned portion of water can be prevented from flowing to the outside through the ventilation channel 1500. In particular, when at least a portion of the second flow segment 1520 is tilted downward, the water can be guided to flow back to the first cavity 1100.

[0059] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present application, the first flow segment 1510 is designed below the second flow segment 1520, so as to simplify the structure. Since the first flow segment 1510 is formed with a first gas port 1511, and the first gas port 1511 needs to be connected to the first cavity 1100, the liner interface 1600 and the liner, and the first gas port 1511 is designed to be higher than the liner interface 1600, based on the need for the second flow segment 1520 to extend from one side of the liner interface 1600 to the other side, the second flow segment 1520 is designed to be higher than the first flow segment 1510, so that the communication path between the first gas port 1511 and the first cavity 1100, the liner interface 1600 and the liner is shorter, and the gas flow is smoother.

[0060] Combination Figure 2As shown, in some embodiments of the present application, the ventilation channel 1500 is designed to extend along the periphery of the water tank 1000, so as to avoid occupying the space of the first cavity 1100 and facilitate the arrangement of various structures.

[0061] Specifically, the ventilation channel 1500 is arranged around the water tank 1000, so that the ventilation channel 1500 can surround the first cavity 1100, so as not to occupy the space of the first cavity 1100. If the ventilation channel 1500 is arranged in the middle of the first cavity 1100, then the first cavity 1100 must avoid the ventilation channel 1500, which increases the complexity of the structure. In addition, generally speaking, the water tank 1000 not only includes the first cavity 1100, but also may include other structures, such as the water inlet channel 1310, the drainage channel 1320, etc., and the ventilation channel 1500 is arranged around the first cavity 1100, which can also avoid other structures, making it easier to arrange each structure.

[0062] For example, in addition to the first flow segment 1510 and the second flow segment 1520 mentioned above, the ventilation flow channel 1500 also includes a third flow segment 1540. The third flow segment 1540 is connected to the second flow segment 1520. The second flow segment 1520 and the first flow segment 1510 are arranged on the upper part of the water tank 1000 and extend in the front-to-back direction. The third flow segment is arranged on the rear side of the water tank 1000 and extends in the up-down direction.

[0063] Combination Figure 2 As shown, in some embodiments of the present application, the water tank 1000 includes a condensation flow channel 1700. By setting the condensation flow channel 1700, condensation of steam overflowing from the inner tank is achieved, preventing the steam from reaching the first cavity 1100 and then being discharged to the outside through the ventilation flow channel 1500.

[0064] Specifically, the condensation channel 1700 extends from the inner liner interface 1600, that is, one end of the condensation channel 1700 is connected to the inner liner interface 1600, so that the condensation channel 1700 and the inner liner interface 1600 are connected, and the condensation channel 1700 extends upward, so that the other end of the condensation channel 1700 is at a higher position relative to the inner liner interface 1600, and the other end of the condensation channel 1700 forms an overflow port 1720. It can be understood that the overflow port 1720 is higher than the inner liner interface 1600, but needs to be lower than the first air port 1511. The overflow port 1720 needs to be connected to the inner liner interface 1600 and the first air port 1511, so that when the water level in the first cavity 1100 continues to rise, the water overflows the overflow port 1720 and can enter the condensation channel 1700 and then flow into the inner liner through the inner liner interface 1600. Since the first air inlet 1511 is higher, the water level will not reach the first air inlet 1511 during normal water inlet, and water will not overflow to the outside through the first air inlet 1511 .

[0065] The dishwasher heats the water in the inner tank when washing, so the steam in the inner tank will enter the condensation channel 1700 through the inner tank interface 1600. The so-called condensation channel 1700 is provided with a plurality of condensation ribs 1710, which increases the condensation area, thereby condensing the steam and preventing the steam from overflowing to the outside.

[0066] Combination Figure 2 , Figure 4 and Figure 6 As shown, the water tank 1000 has a water inlet channel 1310, on which a flow meter 1800 is arranged, and the water inlet channel 1310 is connected to an external water source, the so-called external water source being the water used to provide the dishwasher, such as municipal water, and the water inlet channel 1310 can be connected to a faucet through a pipeline, or the water inlet channel 1310 can be connected to a water storage tank to receive an external water source. The water transported through the water inlet channel 1310 needs to be measured by a flow meter 1800, which is convenient for counting the amount of water injected, for example, the flow meter 1800 is embedded in the water tank 1000. In order to prevent back suction from occurring in the water inlet channel 1310 when receiving an external water source, for example, if a negative pressure occurs in the pipeline corresponding to the faucet, back suction will occur, a pressure relief port 1311 will be arranged on the water inlet channel 1310, and the pressure relief port 1311 needs to be connected to the outside world, so that the phenomenon of back suction can be avoided. Generally speaking, part of the water inlet channel 1310 needs to be designed to be curved to form an upwardly arched structure, and a pressure relief port 1311 is arranged at the lower part of this part of the water inlet channel 1310. The water transported by the water inlet channel 1310 passes over the pressure relief port 1311 under the action of inertia and continues to flow and be transported, while being able to achieve communication with the outside world. Of course, the structure of the pressure relief port 1311 is not limited to this, and the pressure relief port of the dishwasher in the related technology also adopts other structures.

[0067] A pressure relief channel 1410 is provided in the water tank 1000, and the pressure relief channel 1410 is respectively connected to the condensation channel 1700 and the pressure relief port 1311. That is to say, since the condensation channel 1700 is connected to the outside through the first air port 1511, the pressure relief port 1311 is also connected to the outside, thereby maintaining air pressure balance. The connection between the condensation channel 1700 and the pressure relief channel 1410 needs to be designed to be lower than the overflow port 1720. In this way, when water inflows abnormally, too much water will be injected into the first cavity 1100. At this time, the first cavity 1100 has a relatively high pressure. In this way, the water in the water inlet channel 1310 can directly flow out through the pressure relief port 1311 under the action of the relatively high pressure of the first cavity 1100, that is, the pressure relief port 1311 at this time becomes a leakage port, and the water directly flows into the condensation channel 1700 through the pressure relief channel 1410, and then enters the inner tank interface 1600, and then enters the inner tank. Since the connection between the condensation channel 1700 and the pressure relief channel 1410 intersects at a lower position than the overflow port 1720, this can avoid abnormal water inflow causing a large amount of water to be sprayed out to the outside through the ventilation channel 1500.

[0068] It can be understood that since the condensation ribs 1710 are arranged in the condensation flow channel 1700, and the overflow port 1720 is closer to the first air port 1511, when water enters abnormally, the first cavity 1100 has a large water pressure. If the pressure relief flow channel 1410 is not provided, all the water can only be sprayed out from the overflow port 1720, and due to the obstruction of the condensation ribs 1710, the sprayed water forms splashes, so that a part of the water enters the ventilation flow channel 1500 through the first air port 1511. In addition, it is precisely because of the obstruction of the condensation ribs 1710 that the sprayed water has no time to flow downward through the inner tank interface 1600 into the inner tank, which will cause the water level in the condensation flow channel 1700 to rise, so that a part of the water directly enters the ventilation flow channel 1500 from the first air port 1511, and then overflows to the outside. In the present embodiment, a pressure relief channel 1410 is provided, which is equivalent to forming a diversion for the overflow port 1720 to prevent water from being sprayed at the overflow port 1720. Moreover, since the connection between the condensation channel 1700 and the pressure relief channel 1410 is farther from the first air port 1511 than the overflow port 1720, the path of water flowing through the pressure relief channel 1410 into the inner tank interface 1600 is shorter, thereby being discharged faster.

[0069] In some embodiments of the present application, the pressure relief port 1311 is arranged to be higher than the overflow port 1720 and lower than the first air port 1511, so that the pressure relief port 1311 is extremely close to the overflow port 1720, so that when abnormal water inflow occurs, the pressure relief of the pressure relief port 1311 can respond quickly. This is because, at the moment of abnormal water inflow, the amount of water entering the first cavity 1100 increases and the pressure increases. When the pressure reaches a critical point, the water in the water inlet channel 1310 is discharged through the pressure relief port 1311. The pressure formed by the aforementioned critical point is equivalent to the pressure generated by the existence of an assumed water level that is equal to the height of the pressure relief port 1311. Since the pressure relief port 1311 is close to the overflow port 1720, this assumed water level can be reached quickly, thereby achieving a quick response.

[0070] Combination Figure 2 As shown, in some embodiments of the present application, when the condensation flow channel 1700 is set, the flow channel wall of the condensation flow channel 1700 and the flow channel wall of the ventilation flow channel 1500 (first flow section 1510) jointly enclose an overflow port 1720. In this way, when the water tank 1000 is tilted, the instantaneous large-scale passage of water in the first cavity 1100 can be better restrained. For some dishwashers that are temporarily tilted and straightened, such a setting can more effectively prevent water from shaking and entering the ventilation flow channel 1500.

[0071] Combination Figure 4 and Figure 7 As shown, in some embodiments of the present application, since a pressure relief channel 1410 is provided, in order to avoid the pressure relief channel 1410 from obstructing the flow of water, the water tank 1000 has a water flow channel 1420, and the water flow channel 1420 and the pressure relief channel 1410 are overlapped. The so-called overlap means in the thickness direction of the water tank 100, which can save space. In the process of gradually rising water level in the first cavity 1100, at least a part of the water passes through the water flow channel 1420 from bottom to top, and then flows into the overflow port 1720.

[0072] Combination Figure 2 , Figure 4 and Figure 5As shown, in some embodiments of the present application, the water tank 1000 further includes a second cavity 1200. The second cavity 1200 in the water tank 1000 is suitable for communicating with the first cavity 1100. A certain amount of water is also stored in the second cavity 1200. Therefore, the water in the second cavity 1200 can also absorb the heat dissipated, thereby keeping the inner tank warm. The water in the second cavity 1200 flows in from the first cavity 1100. By setting a water inlet 1210, during the process of water injection in the first cavity 1100, when the water level in the first cavity 1100 is higher than the water inlet 1210, the water in the first cavity 1100 enters the second cavity 1200 through the water inlet 1210 until the water in the second cavity 1200 reaches a preset water level. The water in the second cavity 1200 is different from the water in the first cavity 1100 in that the water in the second cavity 1200 is not used for providing a washing cycle, but is used for regenerating the water softener 2000 .

[0073] It is understandable that municipal water is generally used as the water required for the operation of the dishwasher. Municipal water contains more soluble calcium and magnesium (not limited to calcium and magnesium, for example). Since the water temperature of the dishwasher is relatively high during the washing cycle, it is easy to form scale in the circulating water circuit of the dishwasher, affecting the water circulation. In addition, excessive calcium and magnesium content will also affect the efficacy of the detergent. Therefore, the dishwasher will be equipped with a water softener 2000, and the water entering the inner tank needs to be softened by the water softener 2000 to remove calcium and magnesium in the water.

[0074] In the related technology, combined Figure 8 As shown, the water softener 2000 has two chambers, namely a soft water chamber 2100 and a regeneration chamber 2200. The soft water chamber 2100 is provided with a soft water resin. Municipal water flows into the soft water chamber 2100 and then flows out of the soft water chamber 2100. The calcium and magnesium ions in the water are absorbed by the soft water resin, thereby reducing the hardness of the water. When the soft water resin adsorbs calcium and magnesium to a saturated state, the water softening ability of the soft water resin decreases. At this time, the soft water resin needs to be reduced. The reduction of the soft water resin needs to utilize the regeneration chamber 2200.

[0075] The regeneration chamber 2200 is filled with regeneration salt. The regeneration chamber 2200 is provided with a regeneration water inlet 2210. Municipal water or softened water is injected into the regeneration chamber 2200 through the regeneration water inlet 2210 to form brine. The brine is controlled to flow from the regeneration chamber 2200 into the soft water chamber 2100. The brine takes away the calcium and magnesium of the soft water resin, thereby restoring the softening performance of the soft water resin. The brine after restoring the soft water resin needs to be discharged from the soft water chamber 2100.

[0076] That is, the water flow in the water softener 2000 has two routes: one route is that the water flows into the soft water chamber 2100, is discharged from the soft water chamber 2100 after being softened and is input into the inner tank; the other route is that the water flows into the regeneration chamber 2200, then flows from the regeneration chamber 2200 into the soft water chamber 2100, restores the water softening ability of the soft water resin, and finally is discharged from the soft water chamber 2100. Since the water softener 2000 is a common component in the field of dishwashers, only a brief description is given above, and the specific structure can be referred to the relevant technology.

[0077] Because the water softener 2000 needs to be regenerated, the second cavity 1200 of the water tank 1000 is connected to the regenerated water inlet 2210. When the water softener 2000 needs to be regenerated, the water in the second cavity 1200 is discharged into the water softener 2000 to restore the soft water resin of the water softener 2000. In this way, the water tank 1000 not only has the functions of heat preservation and energy saving, but also can realize the regeneration of the water softener 2000.

[0078] The following describes the water tank 1000 in combination with the water softener 2000. Figure 8 As shown, the water softener 2000 includes a soft water inlet 2110, a soft water outlet 2120, and a regenerated water inlet 2210. The soft water inlet 2110 and the soft water outlet 2120 are respectively connected to the soft water chamber 2100 of the water softener 2000, and the regenerated water inlet 2210 is connected to the regeneration chamber 2200 of the water softener 2000. There is a flow channel between the soft water chamber 2100 and the regeneration chamber 2200 that can be switched on and off. The water tank 1000 includes a first inlet 13 12. The first outlet 1313, the second inlet 1110, the second outlet 1220 and the third outlet 1120. The first inlet 1312 and the first outlet 1313 are respectively located at the two ends of the water inlet channel 1310 and are connected to the water inlet channel 1310. The first inlet 1312 is connected to an external water source, for example, through a pipeline to a faucet. The first outlet 1313 is connected to the soft water inlet 2110, and the second inlet 1110 is connected to the soft water outlet 2120.

[0079] The water intake process of the first washing cycle of the dishwasher is as follows: water is taken into the water tank 1000, the water enters the water inlet channel 1310 through the first inlet 1312, then flows out from the first outlet 1313 and enters the soft water chamber 2100 through the soft water inlet 2110, the water is softened in the soft water chamber 2100, then flows out from the soft water outlet 2120, and continues to be injected into the first cavity 1100 through the second inlet 1110. In the process of filling the first cavity 1100, the water in the first cavity 1100 enters the second cavity 1200 through the water port 1210, until the water in the first cavity 1100 reaches a preset water level, and then flows into the inner tank through the inner tank interface 1600. When the water level in the inner tank reaches the preset water level, the water intake is stopped, and the dishwasher uses the water in the inner tank for the first washing cycle.

[0080] After the dishwasher completes the first washing cycle, it needs to drain the water in the inner tank and then enter the second washing cycle. The water intake process of the second washing cycle is as follows: the water in the first cavity 1100 is discharged to the inner tank through the third outlet 1120, and then water is supplied from the external water source, which is similar to the water intake process of the first washing cycle, until the water in the first cavity 1100 reaches the preset water level or until the water in the inner tank reaches the preset water level, and then the water intake is stopped, and the dishwasher uses the water in the inner tank to perform the second washing cycle. It can be seen that the inner tank interface 1600 and the third outlet 1120 are two ways of supplying water to the inner tank, wherein the inner tank interface 1600 allows water to flow into the inner tank from the inner tank interface 1600 when the first cavity 1100 reaches a certain water level, thereby ensuring that when the dishwasher is in a washing cycle, a certain amount of water is stored in the first cavity 1100, and the third outlet 1120 is used to discharge the water in the first cavity 1100 into the inner tank. Since the water in the first cavity 1100 absorbs heat, the energy consumption of the washing cycle can be reduced.

[0081] When the dishwasher completes washing, the first cavity 1100 and the second cavity 1200 contain softened water for use the next time the dishwasher is used.

[0082] When the water softener 2000 needs to be regenerated, the flow channel between the soft water chamber 2100 and the regeneration chamber 2200 is controlled to open, and the water in the second cavity 1200 enters the regeneration chamber 2200 through the second outlet 1220, and the formed brine enters the soft water chamber 2100 to regenerate the soft water resin in the soft water chamber 2100, and then is discharged from the soft water chamber 2100.

[0083] The present application also discloses a dishwasher, which includes the water tank 1000 of the above embodiment. The water tank 1000 can be installed closely on the inner tank, for example, on the left or right side of the inner tank. The heat emitted by the inner tank is absorbed by the water in the water tank 1000. It can be understood that the water tank 1000 of the dishwasher of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0084] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
