Detailed Implementation

[0052] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0053] As shown in Figure 1, the dishwasher 100 according to an embodiment of this application includes a water circuit assembly 40. The dishwasher 100 includes an inner tub 10, a water cup (not shown in the figure), a salt chamber module 30, and a consumable dispensing module 20. The inner tub 10 can hold tableware and other items, and can perform functions such as washing, drying, and / or storing the tableware and other items. The water cup is connected to the bottom of the inner tub. The salt chamber module 30 is used to store salt (store regenerated salt). When the medium in the resin chamber needs to be regenerated, the regenerated salt in the salt chamber can be passed to the resin chamber 42 for medium regeneration. The consumable dispensing module 20 is used for storing and dispensing consumables. The consumable dispensing module 20 is adapted to install or place consumables and is configured to dispense consumables into the inner tub 10 to assist in the cleaning of tableware and other items.

[0054] Specifically, the water circuit assembly 40 has a water inlet channel 41, a brine chamber channel 45, a resin chamber 42, a dispensing channel 43, and a dispensing port 441. The water inlet channel 41 is used for water intake, the brine chamber channel 45 is used to connect to the brine chamber module 30, the resin chamber 42 is used to soften the water, the dispensing channel 43 is used to connect to the consumable dispensing module 20, and the dispensing port 441 is used to dispense the medium.

[0055] In addition, the water circuit assembly 40 includes a switching component 48, which is connected to the water inlet channel 41, the brine chamber channel 45, the resin chamber 42, the dispensing channel 43, and the dispensing port 441. The switching component 48 is used to guide fluid from the water inlet channel 41 into the brine chamber channel 45, wherein the brine chamber channel 45 can deliver fluid to the brine chamber module 30; the switching component 48 is also used to guide the fluid of the brine chamber module 30 into the resin chamber 42 via the brine chamber channel 45; the switching component 48 is also used to guide the fluid from the resin chamber 42 into the dispensing channel 43 to be delivered to the consumable dispensing module 20; the switching component 48 is also used to deliver the fluid of the consumable dispensing module 20 to the dispensing port 441 via the dispensing channel 43.

[0056] When resin regeneration is required, the water entering through the inlet channel 41 can be sent to the salt chamber module 30 through the salt chamber channel 45. The regeneration salt stored in the salt chamber module 30 dissolves in the water after soaking. The switching component 48 is also used to connect the salt chamber channel 45 and the resin chamber 42. The brine in the salt chamber module 30 can flow into the resin chamber 42 through the salt chamber channel 45 to realize the regeneration of the resin in the resin chamber 42. The dispensing channel 43 can guide fluid into the consumable dispensing module 20 to flush or dissolve the consumables in the consumable dispensing module 20. The dispensing channel 43 can also guide fluid from the consumable dispensing module 20 to the dispensing port 441, and finally dispensing it into the inner tank 10 through the dispensing port 441 to complete the dispensing of consumables.

[0057] According to an embodiment of this application, the water circuit assembly 40 of the dishwasher 100 has a salt chamber channel 45, which can be used to connect to the salt chamber module 30. Water can be passed through the water circuit assembly 40 to the salt chamber module 30 to dissolve the salt within the module. The salt solution containing dissolved salt in the salt chamber module 30 can also be passed to the resin chamber 42 for resin regeneration. This simplifies the structure of the water circuit assembly 40, improves its integration, and separates the salt chamber module 30 from the water circuit assembly 40, allowing for convenient placement of the salt chamber module 30 in a suitable salt-adding position and simplifying the user's salt-adding procedure.

[0058] The water circuit assembly 40 in this application can have multiple operating modes. For example, the water circuit assembly 40 can have a first washing water supply mode, a second washing water supply mode, a brine chamber water supply mode, and / or a resin regeneration mode, etc.

[0059] In the first washing water supply mode, the water inlet channel 41, resin chamber 42, and dispensing port 441 are connected. Water flows through the water inlet channel 41 into the resin chamber 42, where it is softened before entering the dispensing port 441, thus supplying the softened water to the inner tank 10. Water enters the water inlet channel 41 through the water inlet 413, then enters the resin chamber 42 for softening, and after softening, it flows to the dispensing port 441 or the consumable dispensing module 20, and is then sent to the inner tank 10 for washing.

[0060] In the second washing water supply mode, the water inlet channel 41, resin chamber 42, dispensing channel 43, and dispensing port 441 are connected. Water flows through the water inlet channel 41 into the resin chamber 42, is softened in the resin chamber 42, enters the dispensing channel 43, and then flows through the dispensing channel 43 into the consumable dispensing module 20. After passing through the consumable dispensing module 20, it enters the dispensing port 441, thus introducing the softened water into the inner tank 10.

[0061] In the water supply mode of the brine chamber module 30, the water inlet channel 41, the resin chamber, and the brine chamber channel 45 are connected. Water can flow through the water inlet channel 41 into the brine chamber channel 45 and then into the brine chamber module 30, facilitating the dissolution of the salt within the module in preparation for resin regeneration. Water enters the water inlet channel 41 through the water inlet 413 and then passes through the brine chamber channel 45 into the brine chamber module 30 to dissolve the salt stored within it.

[0062] In the resin regeneration mode, the brine chamber channel 45 is connected to the resin chamber 42. The brine in the brine chamber module 30 flows into the resin chamber 42 through the brine chamber channel 45, thereby regenerating the resin in the resin chamber 42. After resin regeneration is complete, the water quality can be softened better in the first working mode, improving the washing effect. The brine in the brine chamber module 30 flows into the brine chamber channel 45 through the brine chamber interface 451 and is then sent to the resin chamber 42 through the brine chamber channel 45 to achieve resin regeneration.

[0063] Of course, the water system assembly 40 in this application can implement one or more of the above-mentioned working modes.

[0064] To enable the switching component 48 to switch between different working modes, this application provides some implementation methods.

[0065] In some embodiments, the water inlet channel 41 is kept in communication with the resin chamber 42, and the switching component 48 is configured to control the water inlet channel 41 and the salt chamber channel 45 to be connected or disconnected, and to control the resin chamber 42 and the dispensing port 441 to be connected or disconnected.

[0066] Specifically, when the switching component 48 is configured such that the water inlet channel 41 is disconnected from the salt chamber channel 45 and the resin chamber 42 is connected to the dispensing port 441, water can flow from the water inlet channel 41 into the resin chamber 42 and then into the dispensing port 441 after passing through the resin chamber 42, and the switching component 48 is in the first washing water supply mode.

[0067] When the switching component 48 is configured to connect the water inlet channel 41 and the brine chamber channel 45 and disconnect the resin chamber 42 from the dispensing port 441, water can flow from the water inlet channel 41 into the resin chamber 42 and the brine chamber channel 45. Since the resin chamber 42 is disconnected from the dispensing port 441, the water flow into the resin chamber 42 will be cut off. Therefore, the water flow from the water inlet channel 41 can only flow to the brine chamber channel 45 and then into the brine chamber module 30 after passing through the brine chamber channel 45. The switching component 48 is in the brine chamber water supply mode.

[0068] When the switching component 48 is configured such that the salt chamber channel 45 is connected to the resin chamber 42 and the resin chamber 42 is connected to the inlet 441, the brine in the salt chamber module 30 will flow into the resin chamber 42 through the salt chamber channel 45, thereby realizing the regeneration of the resin in the resin chamber 42, and the switching component 48 is in the resin regeneration mode.

[0069] In other embodiments, the water inlet channel 41 is kept in communication with the resin chamber 42, the return port 435 of the dispensing channel 43 is kept in communication with the dispensing port 441, and the switching component 48 is configured to control the water inlet channel 41 and the salt chamber channel 45 to be connected or disconnected, the resin chamber 42 and the dispensing port 441 to be connected or disconnected, and the resin chamber 42 and the water inlet 432 of the dispensing channel 43 to be connected or disconnected.

[0070] As shown in Figure 2, when the switching component 48 is configured to: disconnect the water inlet channel 41 from the salt chamber channel 45, connect the resin chamber 42 to the dispensing port 441, and disconnect the water inlet 432 of the resin chamber 42 and the dispensing channel 43, water can flow from the water inlet channel 41 into the resin chamber 42, and then into the dispensing port 441 after passing through the resin chamber 42. The switching component 48 is in the first washing water supply mode.

[0071] As shown in Figure 4, when the switching component 48 is configured to connect the water inlet channel 41 to the brine chamber channel 45, disconnect the resin chamber 42 from the injection port 441, and disconnect the resin chamber 42 from the water inlet 432 of the injection channel 43, water can flow from the water inlet channel 41 into the resin chamber 42 and the brine chamber channel 45. However, since the resin chamber 42 is disconnected from the injection port 441 and the injection channel 43, the water flow into the resin chamber 42 will be cut off. Therefore, the water flow from the water inlet channel 41 can only flow to the brine chamber channel 45 and then into the brine chamber module 30. The switching component 48 is in the brine chamber water supply mode.

[0072] As shown in Figure 5, the switching component 48 is configured to connect the salt chamber channel 45 to the resin chamber 42 and the resin chamber 42 to the inlet 441. The brine in the salt chamber module 30 flows into the resin chamber 42 through the salt chamber channel 45, thereby regenerating the resin in the resin chamber 42. When the switching component 48 is in resin regeneration mode, after the resin chamber 42 is filled with brine, the resin chamber 42 is disconnected from the inlet 441 to allow the brine to fully soak and replace the resin. Then, the resin chamber 42 is reconnected to the inlet 441, allowing the regenerated wastewater to be discharged from the resin chamber. Afterward, the system can switch to the first washing water supply mode, where water is supplied to the resin chamber 42 to flush and drain the resin.

[0073] As shown in Figure 3, when the switching component 48 is configured to disconnect the water inlet channel 41 from the salt chamber channel 45, disconnect the resin chamber 42 from the dispensing port, and connect the resin chamber 42 to the dispensing channel 43, water can flow from the water inlet channel 41 into the resin chamber 42. Since the resin chamber 42 is disconnected from the dispensing port 441 and connected to the dispensing channel 43, the water flowing into the resin chamber 42 will flow into the dispensing channel 43. Therefore, the water flowing from the water inlet channel 41 will flow to the dispensing channel 43 and then into the consumable dispensing module 20 after passing through the dispensing channel 43. Subsequently, the consumables in the consumable dispensing module 20 will be dissolved or flushed. At this time, the return port 435 of the dispensing channel 43 is connected to the dispensing port 441. The consumables in the consumable dispensing module 20 are fed into the inner tank 10 through the dispensing port 441. The switching component 48 is in the second washing water supply mode.

[0074] In the foregoing embodiments, the switching component 48 can control the connection or disconnection of the water inlet 432 of the resin chamber 42 and the dispensing channel 43. Therefore, the switching component 48 can be configured to allow unidirectional flow from the resin chamber 42 to the water inlet 432 of the dispensing channel 43, and the opening pressure is not less than a predetermined threshold. Thus, when the water inlet channel 41 and the brine chamber channel 45 are connected and / or the resin chamber 42 and the dispensing port 441 are connected, the opening pressure will not be reached between the resin chamber 42 and the dispensing channel 43 because water can flow into the brine chamber channel 45 or the dispensing port 441, and the connection between the resin chamber 42 and the dispensing channel 43 is disconnected. When the water inlet channel 41 and the brine chamber channel 45 are disconnected, and the resin chamber 42 and the dispensing port 441 are disconnected, water can only flow to the dispensing channel 43, the opening pressure will be reached between the resin chamber 42 and the dispensing channel 43, and the connection between the water inlet 432 of the resin chamber 42 and the dispensing channel 43 is established.

[0075] In some embodiments, the switching component 48 may include: a first control valve 481, a second control valve 482, and a third control valve 483. The first control valve 481 is configured to control the connection or disconnection of the water inlet channel 41 and the brine chamber channel 45; the second control valve 482 is configured to control the connection or disconnection of the resin chamber 42 and the water cup interface; the third control valve 483 is configured to provide unidirectional flow from the resin chamber 42 to the water inlet 432 of the dispensing channel 43, and the opening pressure is not less than a predetermined threshold. Any one of the first control valve 481, the second control valve 482, and the third control valve 483 may be a solenoid valve.

[0076] In conjunction with the aforementioned embodiments, as shown in Figure 2, when the first control valve 481 is closed, the second control valve 482 is open, and the third control valve 483 has not reached its opening pressure, the switching component 48 is in the first washing water supply mode; as shown in Figure 4, when the first control valve 481 is open, the second control valve 482 is closed, and the third control valve 483 has not reached its opening pressure, the switching component 48 is in the brine chamber water supply mode; as shown in Figure 5, when the first control valve 481 is open, the second control valve 482 is open, the third control valve 483 has not reached its opening pressure, and the water inlet 413 of the water inlet channel 41 no longer receives water, the switching component 48 is in the resin regeneration mode; as shown in Figure 3, when the first control valve 481 is closed, the second control valve 482 is closed, and the third control valve 483 reaches its opening pressure, the switching component 48 is in the second washing water supply mode.

[0077] In some embodiments of this application, the dispensing port 441 includes a water cup interface for connecting a water cup to the inner liner 10.

[0078] As shown in Figures 1 and 6, in some embodiments of this application, the water circuit assembly 40 further includes an overflow channel 46 and an overflow interface 461 for connecting the salt chamber module 30. The upper end of the overflow channel 46 is connected to the overflow interface 461, and the lower end is connected to the water cup interface. Specifically, during the use of the dishwasher 100, when the salt chamber module 30 overflows, the overflowing fluid flows into the overflow channel 46 through the overflow interface 461, and then flows into the discharge port 441 through the overflow channel 46, thereby sending out the excess fluid in the salt chamber module 30. The overflowing fluid can be discharged into the inner tank 10 through the discharge port 441, and the fluid entering the inner tank 10 is discharged through the drain channel 403, thereby avoiding problems such as excessive fluid level and flow rate in the salt chamber module 30, which could lead to unstable operation of the dishwasher 100 or fluid overflow in the dishwasher 100. The overflow channel 46 connects to the water cup interface, allowing the fluid overflowing from the salt chamber module 30 to be channeled into the water cup. This facilitates the discharge of the overflowing fluid, prevents corrosion on the inner wall of the inner liner, extends the service life of the inner liner, and makes it easier for the dishwasher 100 to clean it.

[0079] Referring to the aforementioned embodiments, as shown in Figure 1, the dispensing channel 43 may include a first channel 431, a second channel 434, and a third channel. The upper end of the water assembly 40 is provided with a first interface 433 and a second interface 436. The lower end of the first channel 431 is selectively connected to or disconnected from the resin cavity 42, and the upper end of the first channel 431 is connected to the first interface 433. The upper end of the second channel 434 is connected to the second interface 436, and the lower end of the second channel 434 is connected to the lower end of the third channel. The lower end of the third channel is connected to the water cup interface. The lower end of the overflow channel 46 is connected to the third channel and is connected to the water cup interface via the third channel. Therefore, water can be supplied to the consumable dispensing module 20 through the first channel 431, and water and consumables in the consumable dispensing module 20 can be introduced into the dispensing port 441 through the second channel 434, thereby facilitating the dispensing of consumables. As mentioned above, water introduced through inlet 413 can be introduced into the salt chamber module 30 for salt dissolution and carried to the resin chamber 42 for resin regeneration. In order to effectively control the amount of salt added during the resin regeneration process and avoid affecting the stability of the salt chamber module 30 due to excessive water, an overflow structure is also provided in this application. When the amount of water introduced into the salt chamber module 30 is too high, it can overflow through the overflow structure.

[0080] The upper end of the water assembly 40 is also provided with a salt chamber interface 451. The upper end of the salt chamber channel 45 is connected to the salt chamber interface 451, and the lower end of the salt chamber channel 45 is selectively connected to or disconnected from the resin chamber 42. In some embodiments of this application, the channels in the salt chamber channel 45 that supply water to the salt chamber module 30 and the channels in the salt chamber module 30 that supply water to the resin chamber 42 can be one channel or two channels.

[0081] In conjunction with the foregoing, the salt chamber interface 451, overflow interface 461, first interface 433, and second interface 436 are arranged side by side at the upper end of the water circuit assembly 40. This facilitates the connection of the water circuit assembly 40 to the salt chamber module 30 and the consumable dispensing module 20, simplifies the structure of the water circuit assembly 40, facilitates the connection of the water circuit assembly 40 to other components, and improves the stability of the dishwasher 100.

[0082] This application includes a water circuit assembly 40, which supplies water to the inner tank 10, the consumable dispensing module 20, and the brine chamber module 30. This integrates the water circuits supplying the inner tank, the consumable dispensing module 20, and the brine chamber module 30, achieving a modular design for the dishwasher 100 and effectively improving assembly efficiency. Furthermore, integrating the water circuits into the water circuit assembly 40 reduces the number of water circuit joints in the dishwasher 100, lowering the possibility of leaks and optimizing stability. The modular design also allows for timely fault detection and repair, facilitating maintenance of the dishwasher 100.

[0083] During the processes of consumable dispensing and dishwasher 100 operation, inconsistencies in internal and external pressure may occur. For example, the air pressure inside the water circuit assembly 40 may be inconsistent with the external air pressure, or the air pressure inside the inner tank 10 may be inconsistent with the external air pressure. To address this, an air cavity 47 is provided in this application, which is connected to the outside of the dishwasher 100 to balance the air pressure.

[0084] As shown in Figures 1, 7, and 8, in some embodiments of this application, the water circuit assembly 40 further includes an air cavity 47, which is connected to the outside of the dishwasher 100. The air cavity 47 may have a water inlet vent 4705 and a dispensing vent 4706. The water inlet vent 4705 is connected to the water inlet channel 41, and the dispensing vent 4706 is connected to the dispensing channel 43. That is, the air cavity 47 can be configured to be connected to the water inlet channel 41; it can also be configured to be connected to the dispensing channel 43; or it can be configured to be connected to both the water inlet channel 41 and the dispensing channel 43, etc. This can balance the air pressure inside and outside the dishwasher 100, and during fluid flow, it can avoid the problem of increased flow resistance caused by inconsistent internal and external air pressure, thus maintaining the stable operation of the water circuit assembly 40.

[0085] In conjunction with the aforementioned embodiments, the water circuit assembly 40 includes an air cavity 47, which can balance the internal and external air pressure. Specifically, the air cavity 47 is connected to the outside of the dishwasher 100 and has a water inlet vent 4705 connected to the water inlet channel 41 and / or a salt chamber vent connected to the salt chamber channel 45. Thus, the air cavity 47 can balance the internal and external air pressure of the water circuit assembly 40, facilitating water flow from the water inlet 413 into the resin chamber 42, and facilitating water flow from the resin chamber 42 into the first interface 433, thereby reducing fluid resistance and promoting energy conservation and environmental protection.

[0086] As shown in Figures 1, 7, and 8, in some embodiments of this application, the air cavity 47 includes a first cavity 4701 and a second cavity 4702, which are respectively located on opposite sides of the salt cavity channel 45. The first cavity 4701 has an inner tank interface 442, and the water inlet channel 41 has a water inlet vent 4705 that can connect to the second cavity 4702. A connecting channel 4708 is provided between the first cavity 4701 and the second cavity 4702, and the connecting channel 4708 and the salt cavity channel 45 are staggered along the thickness direction of the water assembly 40. This allows for pressure balance between the water inlet channel 41 and the inner tank, improving the operational stability of the dishwasher 100.

[0087] Optionally, as shown in Figures 1, 7, and 8, the water circuit assembly 40 also has a dispensing channel 43 for connecting the consumable dispensing module 20. A first cavity 4701 is located between the dispensing channel 43 and the salt cavity channel 45. The dispensing channel 43 has a dispensing vent 4706 that connects to the first cavity 4701. This allows for pressure balance in the dispensing channel 43 and enables the dispensing channel 43 to balance the pressure inside the inner tank, thereby improving the stability of the dishwasher 100's operation.

[0088] Optionally, as shown in Figures 1, 7, and 8, the air chamber 47 further includes a third chamber 4703. A water inlet vent 4705 connects to the third chamber 4703. A water inlet check valve 471 is provided between the second chamber 4702 and the third chamber 4703, configured for unidirectional flow from the second chamber 4702 to the third chamber 4703. Through the cooperation of the second chamber 4702 and the third chamber 4703, air pressure balance in the water inlet channel 41 can be achieved. When the air pressure in the water inlet channel 41 is low, air can be introduced into the water inlet channel 41 from the inner liner, the dispensing channel 43, etc., to balance the air pressure in the water inlet channel 41. When the air pressure in the water inlet channel 41 is high or water flows into the third chamber 4703, the water inlet check valve 471 can be used to restrict water flow into the second chamber 4702.

[0089] Optionally, as shown in Figures 1, 7, and 8, the water assembly 40 further includes a drainage channel 403 for drainage, and the air chamber 47 includes a fourth chamber 4704. The drainage channel 403 has a drainage vent 4707 connecting to the fourth chamber 4704. A drainage check valve 472 is provided between the second chamber 4702 and the fourth chamber 4704, and is configured to allow unidirectional flow from the second chamber 4702 to the fourth chamber 4704. Through the cooperation of the second chamber 4702 and the fourth chamber 4704, the air pressure balance of the drainage channel 403 can be achieved. When the air pressure of the drainage channel 403 is low, air can be introduced into the drainage channel 403 from the inner liner, the dispensing channel 43, etc., to balance the air pressure of the drainage channel 403. When the air pressure of the drainage channel 403 is high or water flows into the fourth chamber 4704, the drainage check valve 472 can be used to restrict the flow of water into the second chamber 4702.

[0090] As shown in Figures 1, 10, and 11, in some embodiments of this application, the water circuit assembly 40 includes a cavity portion 401 and an integrated water circuit component 402. The integrated water circuit component 402 has a first end and a second end opposite to each other. The cavity portion 401 is connected to the first end of the integrated water circuit component 402, and a resin cavity 42 is provided inside the cavity portion 401. This allows the resin cavity 42 and each channel to be integrated together, and the relatively large cavity portion 401 is located at one end of the integrated water circuit component 402, improving space utilization and facilitating the assembly of the water circuit assembly 40. Furthermore, the water inlet 413 of the water inlet channel 41, the resin cavity 42, the water cup interface, and the switching component 48 are located on the cavity portion 401.

[0091] A schematic diagram of a waterway assembly 40 according to an embodiment of this application is described below with reference to Figures 1 to 12.

[0092] As shown in Figure 1, the water circuit assembly 40 includes a water inlet channel 41, a dispensing channel 43, a salt chamber channel 45, an overflow channel 46, a drainage channel 403, an air chamber 47, and a resin chamber 42, and includes a water inlet 413, a water cup interface, an inner liner interface 442, a first interface 433, a second interface 436, a salt chamber interface 451, and an overflow interface 461. The resin chamber 42 is located at the lower part of the water circuit assembly 40, and the water inlet 413 is located below the resin chamber 42. The water inlet channel 41 includes a first branch 411 and a second branch 412. The lower end of the first branch 411 is connected to the water inlet 413 and extends upward from one side of the resin chamber 42 along the width direction to the upper part of the water circuit assembly 40. The upper end of the second branch 412 is connected to the upper end of the first branch 411, and the lower end extends to the side of the resin chamber 42 and is connected to the first control valve 481. The first control valve 481 has three ports, which are respectively connected to the water inlet channel 41, the upper space of the resin chamber 42, and the lower end of the salt chamber channel 45. The water circuit assembly 40 also includes an intermediate channel, which is connected to the lower end of the resin chamber 42 and extends upward from the other end of the resin chamber 42 in the width direction to connect to the third valve. The lower end of the first channel 431 is connected to the third valve, and the upper end extends to the upper end of the water circuit assembly 40 and connects to the first interface 433. The upper end of the second channel 434 is connected to the second interface 436, and the lower end extends to connect to the water cup interface, which can be located on the upper part of the resin chamber 42.

[0093] As shown in Figure 1, the water system assembly 40 includes a first channel 431, a second channel 434, an overflow channel 46, a salt cavity channel 45, a second branch 412, a first branch 411, and a drainage channel 403 arranged along the width direction. The second channel 434 includes a first part and a second part. The first part and the overflow channel 46 are located above the second part and communicate with the second part. The upper end of the second part has a vent 4706 that connects to the air cavity 47.

[0094] In some embodiments of this application, the following working methods are included:

[0095] As shown in Figure 2, during the pre-wash water intake stage: when the first control valve 481 is closed, the second control valve 482 is open, and the third control valve 483 has not reached the opening pressure, the switching component 48 is in the first washing water supply mode, and the water flow can enter the resin chamber 42 from the water inlet channel 41, and then enter the inlet 441 after passing through the resin chamber 42.

[0096] As shown in Figure 3, during the main wash and rinse water inlet stages: the first control valve 481 is closed, the second control valve 482 is closed, and the third control valve 483 reaches the opening pressure. The switching component 48 is in the second washing water supply mode, and the water flow can enter the resin chamber 42 from the water inlet channel 41. Since the resin chamber 42 is disconnected from the dispensing port 441 and connected to the dispensing channel 43, the water flowing into the resin chamber 42 will flow into the dispensing channel 43. Therefore, the water flow from the water inlet channel 41 will go to the dispensing channel 43 and then enter the consumable dispensing module 20 after passing through the dispensing channel 43. Subsequently, the consumables in the consumable dispensing module 20 are dissolved or flushed to allow the consumables in the consumable dispensing module 20 to be fed into the dispensing port 441.

[0097] As shown in Figure 4, during the brine chamber water inlet stage: when the first control valve 481 is open, the second control valve 482 is closed, and the third control valve 483 has not reached the opening pressure, the switching component 48 is in the brine chamber water supply mode. Water can flow from the water inlet channel 41 into the resin chamber 42 and the brine chamber channel 45. However, since the resin chamber 42 is disconnected from the inlet 441 and the inlet channel 43, the water flowing into the resin chamber 42 will be intercepted. Therefore, the water flowing from the water inlet channel 41 can only flow to the brine chamber channel 45 and then into the brine chamber module 30 after passing through the brine chamber channel 45.

[0098] As shown in Figure 5, during the regeneration stage; when the first control valve 481 is open, the second control valve 482 is open, and the third control valve 483 has not reached its opening pressure, and water no longer enters through the inlet 413 of the water inlet channel 41, the switching component 48 is in resin regeneration mode. The brine in the brine chamber module 30 will flow into the resin chamber 42 through the brine chamber channel 45. After the resin chamber 42 is filled with brine, it is disconnected from the inlet 441, allowing the brine to fully soak and replace the resin, thus regenerating the resin in the resin chamber 42. Subsequently, the resin chamber 42 can be reconnected to the inlet 441 to discharge the regenerated wastewater from the resin chamber. Afterwards, the system can switch to the first washing water supply mode, flushing and draining the resin chamber 42 by circulating water through it.

[0099] As shown in Figure 6, overflow return: At this time, the water circuit assembly 40 may be in a fault state. The first control valve 481 and the second control valve 482 may have water flow or no water flow. The fluid in the salt chamber module 30 flows back to the overflow channel 46 and then flows to the water cup interface after passing through the overflow channel 46.

[0100] As shown in Figure 12, this application also provides a dishwasher 100. According to an embodiment of this application, the dishwasher 100 includes an inner tub 10, which can hold tableware and other items, and can perform functions such as washing, drying, and / or storing the tableware. The dishwasher 100 also includes a salt chamber module 30, which is connected to the inner tub 10. The salt chamber module 30 is used to store regenerated salt. When resin regeneration is required, the regenerated salt in the salt chamber can be passed to the resin chamber 42 for resin regeneration. The dishwasher 100 also includes a water circuit assembly 40, which is disposed on the inner tub 10. A salt chamber channel 45 is connected to the salt chamber module 30, and a dispensing port 441 communicates with the internal space of the inner tub 10. The dishwasher 100 of this application utilizes the water circuit assembly 40 to connect to the salt chamber module 30, allowing water to be passed to the salt chamber module 30 to dissolve the salt within it. It can also pass the salt solution containing dissolved salt from the salt chamber module 30 to the resin chamber 42 for resin regeneration. The structure of the water circuit assembly 40 has been simplified, the integration of the water circuit assembly 40 has been improved, and the salt chamber module 30 has been separated from the water circuit assembly 40, so that the salt chamber module 30 can be easily placed in a suitable salt-adding position, simplifying the user's salt-adding operation steps.

[0101] As shown in Figure 12, in some embodiments of this application, the salt chamber module 30 is located outside the inner liner 10, and at least partially above the inner liner 10. Salt can be placed inside the salt chamber module 30, and after the resin has been used for a period of time, it needs to be regenerated by introducing brine. Brine can be introduced into the resin chamber 42 through the salt chamber module 30. This avoids the influence of water, steam, high temperature, etc. in the inner liner 10 on the regeneration medium stored in the salt chamber module 30, facilitating the stable storage of the regeneration medium in the salt chamber module 30. Furthermore, placing the salt chamber module 30 above the inner liner 10 makes it convenient for users to add salt and other media into the salt chamber module 30. Specifically, by placing the salt chamber module 30 at the top of the dishwasher 100, its relatively high position allows users to add regeneration medium without bending over. This is also more convenient than placing the salt chamber module 30 at the front or side of the dishwasher 100.

[0102] In conjunction with the foregoing, in some examples, the salt chamber module 30 may also have an inlet and an outlet, and the salt chamber interface 451 may include two interfaces respectively connected to the inlet and outlet of the salt chamber module 30. In other examples, the salt chamber module 30 has an inlet and an outlet, and the salt chamber interface 451 is connected to the inlet and outlet. That is, water flows into the salt chamber module 30 through the inlet and outlet, dissolves the salt to form brine, and then flows back to the water circuit assembly 40 and the resin chamber 42 to achieve resin regeneration.

[0103] To facilitate the addition of regeneration medium to the salt chamber module 30, the salt chamber module 30 also has an overflow port. When excessive fluid is introduced into the salt chamber module 30, the fluid can be discharged through the overflow port. The overflow interface 461 is connected to the overflow port. In conjunction with the foregoing, especially when the salt chamber module 30 only uses inlets and outlets for fluid inflow and outflow, the overflow port helps prevent excessive flow into the salt chamber module 30, which could affect the regeneration effect of the resin chamber 42.

[0104] In addition, the dishwasher 100 also includes a consumables dispensing module 20, which is connected to the inner tub 10. The consumables dispensing module 20 is used for dispensing consumables. The consumables dispensing module 20 is adapted to install or place consumables and is configured to dispense consumables into the inner tub 10 to assist in the cleaning of tableware, etc.

[0105] The consumable dispensing module 20 and salt chamber module 30 in this application can be disposed in different positions within the dishwasher 100. For example, one of the consumable dispensing module 20 and salt chamber module 30 can be disposed in different positions such as the top, bottom, side, back, or door 50 of the dishwasher 100. The positions of the consumable dispensing module 20 and salt chamber module 30 can be adjusted according to actual needs. In addition, this application provides some specific placement positions of the consumable dispensing module 20 and salt chamber module 30, but this is not a limitation on the scope of protection of this application. In some embodiments of this application, the consumable dispensing module 20 is disposed on the outside of the inner liner 10, and at least partially disposed above the inner liner 10.

[0106] The consumable dispensing module 20 and the salt chamber module 30 can be arranged side-by-side above the inner tank 10. This allows the salt chamber module 30 and the consumable dispensing module 20 to be placed together, facilitating the production and maintenance of the dishwasher 100 and further improving the space utilization of the dishwasher 100. Alternatively, other discharge methods can be used for the salt chamber module 30 and the consumable dispensing module 20.

[0107] In some embodiments, the water circuit assembly 40 includes an integrated water circuit component 402 and a cavity portion 401. The cavity portion 401 and the integrated water circuit component 402 are connected. The integrated water circuit component 402 is disposed on the side wall of the inner tank 10, and the cavity portion 401 is connected to the integrated water circuit component 402 and located below the inner tank. The integrated water circuit component 402 enables fluid to flow into the consumable dispensing module 20 and the salt chamber module 30, and the resin chamber 42 softens the fluid, thereby optimizing the dishwashing effect of the dishwasher 100 and improving the performance of the dishwasher 100.

[0108] In addition, in conjunction with the foregoing, the upper end of the water circuit assembly 40 in this application is provided with a salt cavity interface 451, an overflow interface 461, a first interface 433, and a second interface 436. The salt cavity interface 451, overflow interface 461, first interface 433, and second interface 436 can be located at the upper end of the integrated water circuit component 402. Above the inner tank 10, there is a consumable dispensing module and a salt cavity module. A first connecting pipe extending in the vertical direction is provided between the first interface 433 and the consumable dispensing module. A second connecting pipe extending in the vertical direction is provided between the second interface 436 and the consumable dispensing module. A third connecting pipe extending in the vertical direction is provided between the overflow interface 461 and the salt cavity module. A fourth connecting pipe extending in the vertical direction is provided between the salt cavity interface 451 and the salt cavity module. The first connecting pipe, the second connecting pipe, the third connecting pipe, and the fourth connecting pipe can be arranged side by side.

[0109] In some embodiments, at least a portion of the cavity portion 401 is located below the inner tub. By placing the cavity portion 401 below the inner tub, the space occupied by the cavity portion 401 can be reduced, the space below the inner tub can be fully utilized, and the space utilization rate can be improved. In addition, the downward placement of the cavity portion 401 can lower the center of gravity of the dishwasher 100 to a certain extent, which is beneficial to improving the stability of the dishwasher 100.

[0110] As shown in Figure 12, the dishwasher 100 may further include a door 50, which is connected to the inner tub and can open and close the washing chamber 101. When the door 50 is open, the washing chamber 101 can be opened to facilitate the placement of tableware to be washed or stored into the washing chamber 101; when the door 50 is closed, the washing chamber 101 can be closed to facilitate the washing of tableware within the washing chamber 101. The consumables dispensing module 20 is located on the upper part of the dishwasher, which can be covered when the door 50 is closed and exposed when the door 50 is open.
