The present application discloses a water tank 1000, and the water tank 1000 will be described in detail with reference to a dishwasher.

As shown in conjunction with fig. 1, 2 and 3, 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 a liner port 1600, the first cavity 1100 is communicated with a liner of a dishwasher through the liner port 1600, water higher than a preset water level of the first cavity 1100 can flow out of the first cavity 1100 through the liner port 1600 and then flow into the liner of the dishwasher, the ventilation flow channel 1500 is communicated with the outside and the first cavity 1100 to achieve air pressure balance, at least part of the ventilation flow channel 1500 extends to two sides of the liner port 1600 beyond the liner port 1600, the ventilation flow channel 1500 includes a first air port 1511, and the first air port 1511 is arranged at one side of the liner port 1600 and is communicated with the first cavity 1100. Through the arrangement of the liner interface 1600, in the process of injecting water into the first cavity 1100, water can be injected into the liner of the dish washer through the liner interface 1600, so that water can be fed into the liner of the dish washer, and meanwhile, the first cavity 1100 can store a certain amount of water, so that heat emitted by the dish washer during operation can be absorbed, and energy consumption is saved; by arranging the ventilation flow channel 1500, at least part of the ventilation flow channel 1500 extends to two sides of the liner interface 1600 beyond the liner interface 1600, water in the first cavity 1100 can be prevented from overflowing to the outside through the ventilation flow channel 1500 when the water tank 1000 is poured, water in the first cavity 1100 can only be injected into the liner of the dish washer through the liner interface 1600, and the situation that the dish washer is soaked due to overflow of water is avoided, so that the water tank 1000 achieves the pouring and water overflowing preventing function.

Specifically, dish washer has the inner bag, sets up bowl basket and spray arm in the inner bag, and the bowl basket can realize loading to the tableware, and the spray arm is used for spouting the rivers in order to wash the tableware. The dish washer is provided with a washing pump, an inlet of the washing pump is communicated with the inner container, an outlet of the washing pump is communicated with the spray arm, a certain amount of water is injected into the inner container when the dish washer works, the washing pump pumps the water in the inner container and conveys the water to the spray arm, the spray arm sprays water flow to clean tableware, and the water flow sprayed by the spray arm falls back into the inner container and is continuously pumped by the washing pump, so that circulation is formed. In order to improve the cleaning effect on the tableware, the water in the inner container is heated, for example, the washing pump is integrated with a heating element, and the water is synchronously heated in the process of pumping the water by the washing pump. Generally, the inner container is made of metal sheet metal or plastic, and even if the inner container is not made of metal sheet metal or plastic, the inner container is difficult to form heat insulation, so that heat can be emitted outwards, and in the embodiment, the water tank 1000 is arranged to absorb the emitted heat so as to save energy consumption.

The water tank 1000 can be installed on the inner bag, hugs closely the inner bag setting, and first cavity 1100 can temporarily store a certain amount of water, and at the in-process of dish washer work, the heat that gives off can be absorbed by the water in the first cavity 1100, avoids thermal dissipation to play the heat retaining effect to the inner bag. The water in the first cavity 1100 is also used to supply the washing water to the inner container, and since the water in the water tank 1000 absorbs the heat emitted from the inner container and has a higher temperature than municipal water, if the water in the first cavity 1100 is input into the inner container, the amount of electricity required for heating during washing is reduced relative to heating only municipal water, thereby reducing power consumption.

For example, when the dishwasher is used for washing (assuming the dishwasher is used for the first time), there are typically a plurality of washing cycles, in which water is filled into the first cavity 1100 first, and water is also introduced into the inner container, during which washing cycle the water in the inner container is heated, and the heat emitted from the inner container is absorbed by the water in the first cavity 1100. When the second washing cycle is entered, the water in the first cavity 1100 can be introduced into the inner container, 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 introduced into the inner container but insufficient for the washing cycle, the municipal water needs to be continuously introduced into the inner container, and the water in the first cavity 1100 absorbs the heat emitted by the inner container during the first washing cycle, so that the electric quantity consumed for heating the water in the inner container during the second washing cycle is reduced. In addition, after the dish washing machine finishes washing dishes, the first cavity 1100 can be filled with water, and the water absorbs environmental heat, so that the temperature of the water in the first cavity 1100 is higher than municipal water when the dish washing machine is used next time, and the energy consumption can be reduced.

The first cavity 1100 is provided with a liner interface 1600, the liner interface 1600 is communicated with the first cavity 1100, the liner interface 1600 is connected to the liner of the dish washer, the liner of the dish washer is provided with a corresponding opening, the liner interface 1600 is connected to the opening on the liner, communication between the first cavity 1100 and the liner of the dish washer is achieved, in the process of injecting water into the first cavity 1100, the water level in the first cavity 1100 is gradually increased until the water level in the first cavity 1100 reaches a preset height (preset water level), when the water level continues to be increased, water higher than the preset water level in the first cavity 1100 flows into the liner of the dish washer through the liner interface 1600 until the water level in the liner reaches the preset height, so that water inflow is stopped, circulating washing water is arranged in the liner at the moment, and the first cavity 1100 of the water tank 1000 stores corresponding water.

Before the first cavity 1100 is filled with water, the first cavity 1100 contains air, and it is difficult to fill the first cavity 1100 with water without exhausting the air. Thus, by providing the ventilation flow channel 1500, the ventilation flow channel 1500 communicates with the outside and the first cavity 1100 for maintaining the balance of the internal and external air pressure of the water tank 1000, where the outside refers to the external atmosphere, for example, one end of the ventilation flow channel 1500 is formed with the first air port 1511, the first air port 1511 communicates with the first cavity 1100, it is understood that since the first air port 1511 needs to communicate with the first cavity 1100 and the outside, meaning that the first air port 1511 needs to be designed to be higher than the liner port 1600 or a preset water level (with the normal placement of the water tank 1000 as a reference), the other end of the ventilation flow channel 1500 is formed with the second air port 1521, and the second air port 1521 communicates with the outside, so that the liner communicates with the outside since the liner port 1600 communicates with the first cavity 1100 and the liner, respectively. When water is injected into the first cavity 1100, air in the first cavity 1100 may pass through the ventilation flow channel 1500 through the first air port 1511 and then be discharged to the outside from the second air port 1521. Because the dish washer needs heating water in the in-process of work, can form certain vapor in the inner bag, the atmospheric pressure in the inner bag is great, because the inner bag passes through ventilation runner 1500 and external intercommunication, consequently can ensure the atmospheric pressure balance of inner bag and external, ensures the normal clear of washing.

Since the ventilation flow channel 1500 is provided to communicate the first cavity 1100 with the outside, when the water tank 1000 is dumped with the dishwasher, water in the first cavity 1100 easily overflows to the outside through the ventilation flow channel 1500, and wets the installation environment of the dishwasher, so that the ventilation flow channel 1500 is particularly important. In this embodiment, the water in the first cavity 1100 is prevented from overflowing, and at least part of the ventilation channel 1500 extends over the liner port 1600 and to opposite sides of the liner port 1600, and it should be noted that, specifically, the opposite sides herein are vertical lines passing through about the center of the liner port 1600 in conjunction with the orientation shown in fig. 2, the front side and the rear side of the vertical lines are opposite sides of the liner port 1600, and at least part of the ventilation channel 1500 extends from the front side (one side) to the rear side (the other side), and it is understood that one side may be regarded as the rear side, and the other side may be regarded as the front side. For example, at least a portion of the vent flow path 1500 is located above the liner port 1600 and extends to the rear and front sides of the liner port 1600, and the first air port 1511 is located at the front side of the liner port 1600, so that when water is stored in the first cavity 1100 and topples over following the dishwasher, a large amount of water is prevented from overflowing outside through the vent flow path 1500.

Taking the forward tilting of the dishwasher as an example, in conjunction with the orientation shown in fig. 2, when the water tank 1000 is in a state of following the forward tilting of the dishwasher, the liner interface 1600 is at a higher position relative to the first air port 1511, water in the water tank 1000 flows into the liner through the liner interface 1600, and at the same time, water also enters the ventilation channel 1500 through the first air port 1511 until the water level in the ventilation channel 1500 is equal to the water level in the first cavity 1100. In the process, a large amount of water in the first cavity 1100 has entered the dishwasher's inner tub through the inner tub interface 1600, so that only a small amount of water enters the ventilation flow path 1500, and in particular, the inner tub interface 1600 is generally designed to be larger than the first air inlet 1511, at which time less water enters the ventilation flow path 1500. Since at least part of the ventilation flow path 1500 extends to opposite sides of the liner, the portion of the ventilation flow path 1500 located at the rear side of the liner port 1600 is higher than the liner port 1600 in this state, and even if water enters the ventilation flow path 1500, it does not quickly overflow to the outside. In the process of resetting the dishwasher, the ventilation flow channel 1500 is inclined at a certain stage, so that water entering the ventilation flow channel 1500 falls back to the first cavity 1100 under the action of gravity, and water entering the ventilation flow channel 1500 is prevented from being discharged to the outside after the dishwasher is reset.

Taking the backward dumping of the dishwasher as an example, in conjunction with the orientation shown in fig. 2, the water tank 1000 is in a state of following the backward dumping of the dishwasher, at this time, the first air port 1511 is at a higher position relative to the liner port 1600, and water in the water tank 1000 flows into the liner through the liner port 1600 until the water level in the first cavity 1100 is lower than the liner port 1600, and in this dumping process, water in the first cavity 1100 has quickly entered into the liner through the liner port 1600, so that the water in the first cavity 1100 is lower than the first air port 1511, and thus water is prevented from entering into the ventilation flow channel 1500. In particular, bladder interface 1600 is typically designed to be larger than first port 1511, where water in first cavity 1100 is more difficult to enter vent flow path 1500 through first port 1511 during rearward pouring of tank 1000.

In some embodiments of the present application, the ventilation channel 1500 includes a second flow section 1520 and a first flow section 1510, the second flow section 1520 is in communication with the first flow section 1510, and the first flow section 1510 is disposed on one side (front side) of the liner interface 1600, and the second flow section 1520 extends from the first flow section 1510 to the other side (rear side) of the liner interface 1600, the second flow section 1520 is connected to the first flow section 1510, and a portion of the second flow section 1520 and the first flow section 1510 form a U-shaped channel 1530, and the first air port 1511 is disposed on the first flow section 1510 and is open toward the other side (rear side).

Specifically, since the second flow section 1520 and the first flow section 1510 are formed with the U-shaped flow passage 1530, that is, the flow passage wall of the first flow section 1510 may form a barrier to sloshing water, the water is prevented from directly rushing into the ventilation flow passage 1500. For example, if the water tank 1000 is in a state of pouring backward along with the dishwasher, if the water tank 1000 is poured at a high speed, the water in the first cavity 1100 may shake rapidly, and the water may overflow to the outside through the first air inlet 1511 when the water flows into the inner container through the inner container port 1600, and by the structure of the U-shaped runner 1530, the U-shaped runner 1530 is in a downward inverted U-shaped state during pouring, the water in the first cavity 1100 may impact the runner wall of the first flow section 1510, and the flowing direction of the water may substantially intersect the first flow section 1510 and be blocked by the first flow section 1510, so that the water in the first cavity 1100 may be prevented from entering the ventilation runner 1500 when the water tank 1000 is poured backward rapidly.

Assuming that a small amount of water enters the breather flow channel 1500 under certain circumstances, in order to enable this portion of water to flow back into the first cavity 1100 more quickly, as shown in fig. 2 and 3, at least a portion of the second flow section 1520 is inclined downward, for example, the breather flow channel 1500 includes a first flow section 1510 and a second flow section 1520, the second flow section 1520 is inclined upward (from another angle, i.e., inclined downward) from the first flow section 1510, when the dishwasher is poured forward, the water in the first cavity 1100 flows into the liner through the liner interface 1600 until the water level is lower than the liner interface 1600, at which time, a portion of the water enters the first flow section 1510 and the second flow section 1520, and when the water tank 1000 is set (reset), the water in the second flow section 1520 and the first flow section 1520 can flow out of the breather flow channel 1500 through the first air port 1511 and then flow back into the first cavity 1100 or the liner under the action of this inclined portion of the second flow section 1520.

Further, as shown in connection with fig. 2, in some embodiments of the present application, at least a portion of the second flow section 1520 may also be designed to be upwardly arched, such that water in the second flow section 1520 is prevented from being discharged to the outside. When the dishwasher is poured forward, water in the first chamber 1100 flows into the inner container through the inner container port 1600 until the water level is lower than the inner container port 1600, at this time, a part of water enters the first flow section 1510 and the second flow section 1520, and when the water tank 1000 is swung, the water in the second flow section 1520 may not flow back to the first chamber 1100 due to the rapid swing of the water tank 1000, and the aforementioned part of water is prevented from flowing to the outside through the ventilation flow channel 1500 by at least partially arching the second flow section 1520, and particularly, when at least a part of the second flow section 1520 is inclined downward, the water is more guided to flow back to the first chamber 1100.

As shown in connection with fig. 2 and 3, in some embodiments of the present application, the first flow section 1510 is designed below the second flow section 1520, thus simplifying the structure. Because the first flow section 1510 is formed with the first air port 1511, and the first air port 1511 needs to be communicated with the first cavity 1100, the liner interface 1600 and the liner, and the first air port 1511 is designed to be higher relative to the liner interface 1600, the second flow section 1520 is designed to be higher relative to the first flow section 1510 based on the second flow section 1520 needing to extend from one side to the other side of the liner interface 1600, so that the communication path between the first air port 1511 and the first cavity 1100, the liner interface 1600 and the liner is shorter, and the air circulation is smoother.

In some embodiments of the application, as shown in connection with fig. 2, the vent flow channel 1500 is designed to extend along the perimeter of the water tank 1000, so as to avoid encroaching on the space of the first cavity 1100, and to facilitate the arrangement of the structures.

Specifically, the ventilation flow channel 1500 is disposed at the periphery of the water tank 1000, so that the ventilation flow channel 1500 can form a surrounding to the first cavity 1100, so that the space of the first cavity 1100 is not occupied, and if the ventilation flow channel 1500 is disposed in the middle of the first cavity 1100, the ventilation flow channel 1500 needs to be avoided by the first cavity 1100, thereby increasing the structural complexity. In addition, in general, the water tank 1000 not only includes the first cavity 1100, but also may include other structures, such as a water inlet channel 1310, a water outlet channel 1320, etc., where the ventilation channel 1500 is disposed around the first cavity 1100, so that other structures can be avoided, and the structures are more convenient to be arranged.

For example, the vent flow path 1500 includes a third flow section 1540 in addition to the first flow section 1510 and the second flow section 1520 mentioned above, the third flow section 1540 communicating with the second flow section 1520, the second flow section 1520 and the first flow section 1510 being provided at an upper portion of the water tank 1000 and extending in the front-rear direction, and the third flow section being provided at a rear side of the water tank 1000 and extending in the up-down direction.

In some embodiments of the present application, as shown in fig. 2, the water tank 1000 includes a condensation channel 1700, and by providing the condensation channel 1700, condensation of the steam overflowed from the liner is achieved, so that the steam is prevented from flowing into the first cavity 1100 and then is discharged to the outside through the ventilation channel 1500.

Specifically, the condensation runner 1700 extends from the liner interface 1600, that is, one end of the condensation runner 1700 is connected with the liner interface 1600, so as to realize communication between the condensation runner 1700 and the liner interface 1600, and the condensation runner 1700 extends upwards, so that the other end of the condensation runner 1700 is located at a higher position relative to the liner interface 1600, and an overflow port 1720 is formed at the other end of the condensation runner 1700. It will be appreciated that the overflow 1720 is higher than the liner port 1600, but needs to be lower than the first air port 1511, and the overflow 1720 needs to communicate with the liner port 1600 and the first air port 1511, so that when the water level in the first cavity 1100 continuously rises, water can enter the condensation channel 1700 through the overflow 1720 and then flow into the liner through the liner port 1600. Since the first air inlet 1511 is higher, water will not overflow to the outside through the first air inlet 1511 when water is normally supplied and the water is not supplied to the first air inlet 1511.

The water in the liner can be heated when the dish washer is washed, so that steam in the liner can enter the condensation flow passage 1700 through the liner interface 1600, and the condensation flow passage 1700 is provided with a plurality of condensation ribs 1710, so that the condensation area is increased, the steam is condensed, and the steam is prevented from overflowing to the outside.

As shown in fig. 2, 4 and 6, the water tank 1000 has a water inlet flow channel 1310, a flow meter 1800 is provided on the water inlet flow channel 1310, the water inlet flow channel 1310 is connected to an external water source, i.e. water for supplying dishwasher operation, such as municipal water, the water inlet flow channel 1310 may be connected to a tap through a pipeline, or the water inlet flow channel 1310 may be connected to a water storage tank to receive the external water source. The water delivered through the water inlet channel 1310 needs to be measured by the flow meter 1800, so that the water injection amount can be conveniently counted, for example, the flow meter 1800 is embedded in the water tank 1000. In order to prevent the back suction from occurring in the water inlet channel 1310 when receiving an external water source, for example, if a negative pressure occurs in a pipeline corresponding to the faucet, the back suction occurs, a pressure relief port 1311 is provided on the water inlet channel 1310, and the pressure relief port 1311 needs to be communicated with the outside, so that the back suction phenomenon can be avoided. Generally, a portion of the water inlet channel 1310 needs to be curved to form an upwardly arched structure, and a pressure relief port 1311 is provided at a lower portion of the water inlet channel 1310, so that water conveyed by the water inlet channel 1310 passes through the pressure relief port 1311 under the action of inertia to continue flowing and conveying, and meanwhile, communication with the outside can be achieved, however, the structure of the pressure relief port 1311 is not limited to this, and other structures are adopted as the pressure relief port of the dish washer in the related art.

The water tank 1000 is provided with the pressure release flow channel 1410, and the pressure release flow channel 1410 is respectively communicated with the condensation flow channel 1700 and the pressure release port 1311, that is, because the condensation flow channel 1700 is communicated with the outside through the first air port 1511, the pressure release port 1311 is also communicated with the outside, so that the air pressure balance can be maintained, and the connection part between the condensation flow channel 1700 and the pressure release flow channel 1410 needs to be designed to be lower than the overflow port 1720. So when unusual intaking, can pour into too much water into in the first cavity 1100, at this moment first cavity 1100 has great pressure, so the water in the intake runner 1310 can directly flow out through pressure release port 1311 under the effect of first cavity 1100 great pressure, pressure release port 1311 at this moment has become the bleeder port promptly, these water directly flow into condensation runner 1700 through pressure release runner 1410 to enter into inner bag interface 1600, then into the inner bag, because condensation runner 1700 and pressure release runner 1410's junction intersects at overflow port 1720 lower, so can avoid unusual intaking to lead to a large amount of water to spout outside through ventilation runner 1500.

It will be appreciated that, since the condensation rib 1710 is disposed in the condensation flow channel 1700, and the water overflow hole 1720 is closer to the first air inlet 1511, when water is abnormally fed, the first cavity 1100 has a larger water pressure, if the pressure release flow channel 1410 is not provided, all water can be sprayed out of the water overflow hole 1720, and due to the blocking of the condensation rib 1710, the sprayed water forms splashes, so that a part of water enters the ventilation flow channel 1500 through the first air inlet 1511, and in addition, due to the blocking of the condensation rib 1710, the sprayed water does not flow down through the liner interface 1600 to enter the liner, which can cause the water level in the condensation flow channel 1700 to rise, so that a part of water directly enters the ventilation flow channel 1500 from the first air inlet 1511 and overflows to the outside. In this embodiment, the pressure release flow channel 1410 is provided, which is equivalent to splitting the overflow hole 1720, so as to avoid water from being sprayed at the overflow hole 1720, and the connection between the condensation flow channel 1700 and the pressure release flow channel 1410 is further away from the first air inlet 1511 than the overflow hole 1720, so that the path of water flowing through the pressure release flow channel 1410 to the liner interface 1600 is shorter, and the water is discharged faster.

In some embodiments of the present application, the pressure relief port 1311 is disposed higher than the water overflow port 1720 and lower than the first air port 1511, such that the pressure relief port 1311 is very close to the water overflow port 1720, so that the pressure relief of the pressure relief port 1311 can be rapidly responded when abnormal water inflow occurs, because if the water amount entering the first cavity 1100 increases at the moment of abnormal water inflow, the pressure becomes large, and the water in the water inlet flow channel 1310 is discharged through the pressure relief port 1311 when the pressure is large to a critical point, the pressure formed by the critical point corresponds to the pressure generated by the existence of a hypothetical water level equal to the pressure of the pressure relief port 1311, and the hypothetical water level can be rapidly reached due to the close of the pressure relief port 1311 to the water overflow port 1720, so that the rapid response is realized.

In some embodiments of the present application, as shown in fig. 2, when the condensation runner 1700 is provided, the overflow 1720 is enclosed by the runner wall of the condensation runner 1700 and the runner wall of the ventilation runner 1500 (the first flow section 1510), so that when the water tank 1000 is poured, the water in the first cavity 1100 is more restricted from passing through instantaneously, and for some dish washers to be temporarily poured and aligned, the arrangement can more effectively avoid the shaking of the water into the ventilation runner 1500.

In some embodiments of the present application, as a pressure release flow channel 1410 is provided, in order to avoid the obstruction of the pressure release flow channel 1410 to the flow of water, the water tank 1000 has a water flow channel 1420, and the water flow channel 1420 and the pressure release flow channel 1410 are overlapped, that is, in the thickness direction of the water tank 100, the overlapping is that the space is saved, and at least a part of water passes through the water flow channel 1420 from bottom to top and then flows into the overflow port 1720 in the process of gradually increasing the water level in the first cavity 1100.

As shown in fig. 2, 4 and 5, 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 adapted to communicate with the first cavity 1100, and a certain amount of water is stored in the second cavity 1200, so that the water in the second cavity 1200 can absorb heat of heat dissipation, thereby playing a role in insulating the inner container. The water in the second cavity 1200 flows in from the first cavity 1100, and through the water through hole 1210, when the water level of the first cavity 1100 is higher than the water through hole 1210 in the water injection process of the first cavity 1100, the water in the first cavity 1100 enters into the second cavity 1200 through the water through hole 1210 until the water in the second cavity 1200 reaches the preset water level. The water in the second chamber 1200 is different from the water in the first chamber 1100 in that the water in the second chamber 1200 is not used to provide a washing cycle, but is used to provide regeneration of the water softener 2000.

It will be appreciated that municipal water is generally used as the water required for the operation of the dishwasher, which contains more soluble calcium and magnesium (not limited to calcium and magnesium, for example) and is subject to scale formation in the water circulation path of the dishwasher due to the relatively high water temperature of the dishwasher during the washing cycle, which affects the circulation of water. In addition, too high calcium and magnesium content can affect the efficacy of the detergent, so the dishwasher is provided with the water softener 2000, and the water introduced into the inner container needs to be softened by the water softener 2000 to remove calcium and magnesium in the water.

In the related art, as shown in connection with fig. 8, the water softener 2000 has two chambers, a soft water chamber 2100 and a regeneration chamber 2200, respectively, the soft water chamber 2100 is provided with soft water resin, municipal water flows into the soft water chamber 2100, and then flows out of the soft water chamber 2100, calcium and magnesium ions in the water are absorbed by the soft water resin, so that the hardness of the water is reduced, when the soft water resin adsorbs calcium and magnesium to reach a saturated state, the soft water capability of the soft water resin is reduced, at this time, the soft water resin needs to be reduced, and the reduction of the soft water resin needs to be utilized to the regeneration chamber 2200.

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 into the soft water chamber 2100 from the regeneration chamber 2200, the brine takes away calcium and magnesium of the soft water resin, so that the softening performance of the soft water resin can be recovered, and the brine after the soft water resin is reduced needs to be discharged out of the soft water chamber 2100.

That is, the flow direction of water in the water softener 2000 has two lines: one line is that water flows into the soft water chamber 2100, is softened, and is discharged from the soft water chamber 2100 and input into the liner; another line is that water flows into the regeneration chamber 2200, then flows from the regeneration chamber 2200 into the soft water chamber 2100, reduces the soft water capacity 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 dishwasher field, the above description is only briefly made, and a specific structure can be seen in the related art.

Also, since the water softener 2000 needs to be regenerated, the second cavity 1200 of the water tank 1000 is communicated with the regenerated water inlet 2210, when the water softener 2000 needs to be regenerated, water in the second cavity 1200 is discharged into the water softener 2000 to reduce soft water resin of the water softener 2000, so that the water tank 1000 has the functions of heat preservation and energy consumption saving, and the regeneration of the water softener 2000 can be realized.

The following description of the water tank 1000 with reference to the water softener 2000, continuing to refer to fig. 8, the water softener 2000 includes a soft water inlet 2110, a soft water outlet 2120, a regeneration 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, the regeneration water inlet 2210 is connected to the regeneration chamber 2200 of the water softener 2000, an on-off flow path is provided between the soft water chamber 2100 and the regeneration chamber 2200, the water tank 1000 includes a first inlet 1312, a first outlet 1313, a second inlet 1110, a second outlet 1220 and a third outlet 1120, the first inlet 1312 and the first outlet 1313 are respectively positioned at two ends of the water inlet flow path 1310, and the water inlet flow path 1310 is connected, the first inlet 1312 is connected to an external water source, for example, 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.

The water inlet process of the first washing cycle of the dishwasher is as follows, water is introduced into the water inlet flow channel 1310 through the first inlet 1312, then flows out from the first outlet 1313 and into the soft water chamber 2100 through the soft water inlet 2110, softening of the water is realized in the soft water chamber 2100, then flows out from the soft water outlet 2120, and is continuously injected into the first cavity 1100 through the second inlet 1110, during the process of filling the first cavity 1100, the water in the first cavity 1100 enters into the second cavity 1200 through the water inlet 1210, until the water in the first cavity 1100 reaches a preset water level, flows into the liner through the liner interface 1600, and when the water level in the liner reaches the preset water level, the water inlet is stopped, and the dishwasher performs the first washing cycle by using the water in the liner.

When the dishwasher completes the first washing cycle, water in the inner container needs to be drained away and then enters the second washing cycle, the water inlet process of the second washing cycle is as follows, water in the first cavity 1100 is drained to the inner container through the third outlet 1120, then water supply of an external water source is performed, and the dishwasher performs the second washing cycle by using the water in the inner container, similar to the water inlet process of the first washing cycle, until the water in the first cavity 1100 reaches a preset water level or until the water in the inner container reaches the preset water level, and then water inlet is stopped. Therefore, the liner interface 1600 and the third outlet 1120 are two ways of supplying water to the liner, wherein the liner interface 1600 flows into the liner from the liner interface 1600 when the first cavity 1100 reaches a certain water level, so as to ensure that a certain amount of water is stored in the first cavity 1100 when the dishwasher is in a washing cycle, and the third outlet 1120 is used for discharging the water in the first cavity 1100 to be discharged into the liner, and the energy consumption of the washing cycle can be reduced because the water in the first cavity 1100 absorbs heat.

When the dishwasher finishes washing, the first and second chambers 1100 and 1200 contain softened water for use when the dishwasher is used next time.

When it is required to regenerate the water softener 2000, a flow passage between the soft water chamber 2100 and the regeneration chamber 2200 is controlled to be opened, water in the second chamber 1200 is introduced into the regeneration chamber 2200 through the second outlet 1220, the formed brine is introduced into the soft water chamber 2100, soft water resin of the soft water chamber 2100 is regenerated, and then the soft water chamber 2100 is discharged.

The application also discloses a dish washer, which comprises the water tank 1000 of the embodiment, wherein the water tank 1000 can be closely arranged on the inner container, for example, the water tank 1000 is arranged on the left side or the right side of the inner container, and the heat emitted by the inner container is absorbed by the water in the water tank 1000.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the application, and all equivalent structural changes made by the specification and drawings of the present application or direct/indirect application in other related technical fields are included in the scope of the present application.
