[0052] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 the present invention, and should not be construed as limiting the present invention.

[0053] As shown in Figure 1, the dishwasher 100 according to an embodiment of the present invention includes a water circuit assembly 40. The dishwasher 100 includes an inner tub 10 and a consumable dispensing module 20. The inner tub 10 can hold tableware, etc., and is used to perform functions such as washing, drying and / or storing tableware, etc. The consumable dispensing module 20 is used for 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, etc.

[0054] Specifically, the water circuit assembly 40 includes an integrated water circuit component 402 and a resin chamber 401. The integrated water circuit component 402 is provided with a water inlet channel 41, a dispensing channel 43, and an inner tank interface 42. The water inlet channel 41 is used for water intake. The resin chamber 401 can be filled with resin or other materials to soften the water. The dispensing channel 43 is used to connect to the consumable dispensing module 20. The inner tank interface 42 is used to dispense media into the inner tank 10. Water, consumables, and other media for washing can be dispensed into the inner tank 10 through the inner tank interface 42. The dispensing channel 43 is connected to both the resin chamber 401 and the inner tank interface 42. The dispensing channel 43 can guide fluid from the water inlet channel 41 through the resin chamber 401 and the dispensing channel 43, and then into the consumable dispensing module 20 to flush or dissolve the consumables inside the consumable dispensing module 20. The dispensing channel 43 can also guide fluid from the consumable dispensing module 20 through the dispensing channel 43 to the inner tank interface 42, and finally into the inner tank 10 through the inner tank interface 42 to complete the dispensing of consumables.

[0055] According to an embodiment of the present invention, the water circuit assembly 40 of the dishwasher 100 connects the consumable dispensing module 20 and the inner tank 10, guides the water flow to flush the consumables in the consumable dispensing module 20 and dispense them into the inner tank 10, thereby achieving effective dispensing of consumables.

[0056] This invention features a water circuit assembly 40, which supplies water to the inner tank 10 and the consumable dispensing module 20. This integrates the water supply lines to the inner tank 10 and the consumable dispensing module 20, 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.

[0057] The dispensing channel 43 in this invention can be a single channel, through which water is introduced into the consumable dispensing module 20, and then the water carrying the consumables flows back through the channel to complete the dispensing. It can also be two or more channels. This invention is mainly described using the dispensing channel 43, including the first channel 431 and the second channel 432, as an example. This is not a limitation on the scope of protection of this invention.

[0058] As shown in Figure 1, in some embodiments, the dispensing channel 43 includes a first channel 431, one end of which is connected to the resin cavity 401, and the other end is connected to the consumable dispensing module. The dispensing channel 43 also includes a second channel 432, one end of which is connected to the consumable dispensing module, and the other end of which is connected to the inner liner interface 42. The first channel 431 can be configured to extend vertically in the integrated water circuit assembly, and the second channel 432 can also be configured to extend vertically in the integrated water circuit assembly, thereby facilitating fluid flow.

[0059] The integrated water circuit component 402 has a first interface and a second interface at its upper end. The first channel 431 is connected to the consumable dispensing module via the first interface 433; the second channel 432 is connected to the consumable dispensing module 20 via the second interface 434. The lower end of the first channel is connected to the resin cavity 401, and the lower end of the second channel is connected to the inner liner interface.

[0060] Specifically, the water inlet channel 41 may have a water inlet 413, through which water can enter the water inlet channel 41. After passing through the water inlet channel 41, the water flows through the resin cavity 401 into the first channel 431, and then through the first channel 431 into the consumable dispensing module 20 from the first interface 433. This flushes the media dispensed in the consumable dispensing module 20. After flushing, the water will carry the media from the second interface 434 through the second channel 432 and dispense it from the inner tank interface 42. By setting the first channel 431 and the second channel 432, the consumables can be dispensed quickly, improving the efficiency of consumable dispensing and facilitating the improvement of the operating efficiency of the dishwasher 100.

[0061] In this invention, the water cup interface 44 can be an interface on the water circuit assembly 40 for connecting a water cup; the inner liner interface 42 can be an interface on the water circuit assembly 40 for connecting an inner liner 10.

[0062] In some embodiments of the present invention, the inner liner interface 42 is used to connect the inner liner 10, and consumables can be introduced into the inner liner 10, so that the second channel 432 can introduce consumables into the inner liner 10 nearby, shortening the pipeline and improving the stability of the dishwasher 100 operation.

[0063] In this invention, the first channel 431 can be configured to extend vertically, with its lower end connected to the resin cavity 401; the second channel 432 can also be configured to extend vertically, with its lower end connected to the inner liner interface 42. Furthermore, the first interface 433 and the second interface 434 are located at the upper end of the water circuit assembly 40, and can be arranged side-by-side to facilitate pipe connection and maintenance.

[0064] The water circuit assembly 40 has a resin chamber 401, an inlet channel 41 connected to the resin chamber 401, and a dispensing channel 43 connected to the resin chamber 401. After the water flows into the resin chamber 401, it will be softened by the soft water medium (resin, etc.) in the resin chamber 401 to remove hard water minerals in the water flow, and then sent out through the dispensing channel 43, thereby optimizing the water quality and facilitating the cleaning of tableware, etc.

[0065] The water circuit assembly of the present invention also has a water cup interface for connecting a water cup, and the water circuit assembly 40 of the present invention has multiple water circuit modes.

[0066] In the first water path mode, the water inlet channel 41, resin chamber 401, dispensing channel 43, and inner tank interface 42 are sequentially connected. Water flows from the water inlet channel 41 into the resin chamber 401, then into the dispensing channel 43, carrying the consumables from the consumable dispensing module 20 to the inner tank interface 42 to complete the dispensing. This achieves water softening and consumable dispensing, facilitating the operation of the dishwasher 100.

[0067] In the second water path mode, the water inlet channel 41 and the water cup interface 44 are connected, wherein the water cup interface 44 is used to supply water to the water cup. Specifically, the water inlet channel 41 can be switched to connect to the resin chamber 401 or the water cup interface 44. In other words, the water path assembly 40 has a first water path mode and a second water path mode. In the first water path mode, the water inlet channel 41 is connected to the resin chamber 401, and the water flows in the manner described above. In the second water path mode, the water inlet channel 41 is connected to the water cup interface 44, and the water flowing from the water inlet channel 41 flows to the water cup interface 44 and enters the inner tank 10. This allows the water flowing from the water inlet 413 to be sent to the inner tank 10, thereby enabling different water flow methods to be used in different operating cycles of the dishwasher 100 to meet the rinsing needs of consumables under different washing water path modes.

[0068] In addition, the integrated water circuit assembly 402 also has a brine cavity channel 45 for connecting the brine cavity module 30. The integrated water circuit assembly 402 also has a regeneration inlet water circuit mode and a regeneration return water circuit mode. In the regeneration inlet water circuit mode, the inlet channel, the resin cavity 401, and the brine cavity module are connected in sequence. In the regeneration return water circuit mode, the brine in the brine cavity module flows back to the resin cavity 401 through the brine cavity channel. Specifically, the resin cavity 401 can be switched to be connected to the dosing channel 43 or the brine cavity channel 45. The integrated water circuit assembly 402 has a first water circuit mode, a regeneration inlet water circuit mode, and a regeneration return water circuit mode.

[0069] For example, the water circuit assembly 40 may further include a first reversing member 481, which is connected to the water inlet channel 41, the resin chamber 401, and the water cup interface 44, and configured to allow the water inlet channel 41 to switchably connect to either the resin chamber 401 or the water cup interface 44. The flow path of the water can be adjusted by the first reversing member 481. In the first water circuit mode, the water inlet channel is connected to the resin chamber 401, and in the second water circuit mode, the water inlet channel is connected to the water cup interface.

[0070] Additionally, the water circuit assembly 40 may further include a second reversing component 482. The second reversing component 482 is connected to both the resin chamber 401 and the brine chamber channel 45, and is configured to allow the resin chamber 401 to be switchably connected to either the dispensing channel 43 or the brine chamber channel 45. In both the regeneration inlet water circuit mode and the regeneration return water circuit mode, the second reversing component is switched to connect the resin chamber 401 and the brine chamber channel. The second reversing component 482 allows switching the channel connected to the resin chamber 401. The second reversing component 482 can be a solenoid valve, and the first reversing component 481 can also be a solenoid valve.

[0071] Optionally, the water inlet channel is located on one side of the integrated water circuit component 402, the dispensing channel 43 is located on the opposite side of the integrated water circuit component 402, and the salt chamber channel is located between the water inlet channel and the dispensing channel 43.

[0072] Optionally, the upper end of the salt cavity channel is located at the upper end of the integrated water circuit assembly 402, and the lower end is located at the lower end of the integrated water circuit assembly 402. The lower end of the salt cavity channel can be positioned above the resin cavity 401. Furthermore, the salt cavity channel in the integrated water circuit assembly is configured to extend vertically to facilitate fluid flow.

[0073] In addition, the water inlet channel may include a first branch and a second branch arranged side by side. The lower end of the first branch is located below the resin cavity 401, and the upper end is located above the integrated water circuit assembly 402. The upper end of the second branch is connected to the upper end of the first branch, and the lower end is located at the lower end of the integrated water circuit assembly 402 and above the resin cavity 401.

[0074] In conjunction with the foregoing, in some embodiments of the present invention, the water inlet channel 41 can be switched to connect to the resin chamber 401 or the water cup interface 44 (refer to Figure 1, switched using the first reversing member 481), and the resin chamber 401 can be switched to connect to the dispensing channel 43 or the salt chamber channel 45 (refer to Figure 1, switched using the second reversing member 482).

[0075] Waterway assembly 40 includes the following operating modes:

[0076] As shown in Figure 2, during the pre-wash water inlet stage: the first reversing component 481 switches to the water inlet channel 41 to connect to the water cup interface 44, and the water flows to the water cup interface 44.

[0077] As shown in Figure 3, during the main wash and rinsing water inlet stages: the first reversing component 481 switches to the water inlet channel 41 to connect with the resin chamber 401, and the second reversing component 482 switches to the resin chamber 401 to connect with the dispensing channel 43. The water flows into the resin chamber 401, and after passing through the resin chamber 401, it flows into the consumable dispensing module 20, and after passing through the consumable dispensing module 20, it flows into the dispensing channel 43, and then flows into the inner tank interface 42.

[0078] As shown in Figure 4, during the regeneration water intake stage: the first reversing component 481 switches to the water intake channel 41 to connect with the resin chamber 401, and the second reversing component 482 switches to the resin chamber 401 to connect with the salt chamber channel 45. The water flows into the resin chamber 401, and after passing through the resin chamber 401, it flows into the salt chamber channel 45, and after passing through the salt chamber channel 45, it flows into the salt chamber module 30.

[0079] As shown in Figure 5, during the regeneration and return water stage, the first reversing component 481 switches to the resin chamber 401 to connect to the water cup interface 44, and the second reversing component 482 switches to the resin chamber 401 to connect to the salt chamber channel 45. The fluid in the salt chamber module 30 flows back to the salt chamber channel 45, and after passing through the salt chamber channel 45, it flows to the resin chamber 401, and after passing through the resin chamber 401, it flows to the water cup interface 44.

[0080] As shown in Figure 6, overflow return: At this time, the water circuit assembly 40 may be in a fault state. The first commutator 481 and the second commutator 482 may have water flow or no water flow. The fluid in the salt cavity module 30 flows back to the overflow channel 46 and then flows to the inner liner interface 42 after passing through the overflow channel 46.

[0081] As mentioned above, in some embodiments of the present invention, the dishwasher also includes a salt chamber module 30 for adding regenerated salt, thereby facilitating resin regeneration. Additionally, when water flows into the salt chamber module 30 to dissolve salt, a malfunction may cause excessive water flow, requiring the water in the salt chamber module 30 to be drained. Therefore, the water circuit assembly 40 of the present invention also has an overflow channel 46 for connecting to the salt chamber module. The water circuit assembly 40 also has an overflow interface; one end of the overflow channel 46 can be connected to the salt chamber module 30 via the overflow interface 461, and the other end can be connected to the inner tank interface. Excess water in the salt chamber module 30 will flow into the overflow channel 46 through the overflow interface 461, and subsequently into the inner tank interface 42 through the overflow channel 46, thus diverting excess water into the inner tank 10 and allowing it to be drained through the drainage structure of the inner tank 10, thereby maintaining the stability of the water circuit assembly 40 and the dishwasher 100. This avoids problems such as unstable operation of the dishwasher 100 or fluid overflow in the dishwasher 100 caused by excessive fluid level and flow rate in the salt chamber module 30.

[0082] In other embodiments of the present invention, the overflow channel 46 is connected to the inner liner interface 42, which is used to connect to the inner liner 10 of the inner liner 10. The overflow channel 46 is connected to the inner liner interface 42. Fluid overflowing from the salt chamber module 30 can be introduced into the inner liner 10. This allows the overflow channel 46 to conveniently introduce the fluid overflowing from the salt chamber module 30 into the inner liner 10, shortening the pipeline and improving the operational stability of the dishwasher 100.

[0083] During the operation of the dishwasher 100, inconsistencies in internal and external pressure can easily occur. For example, the air pressure inside the water circuit assembly 40 may differ from the external air pressure; or the air pressure inside the inner tub 10 may differ from the external air pressure. To address this, the present invention includes a water inlet air chamber 471, which connects to the outside of the dishwasher 100 to balance the air pressure. This prevents excessive pressure in the washing chamber 101 during the washing process and also avoids siphoning in the drain pipe and water inlet pipe.

[0084] The anti-siphon structure in this invention includes, but is not limited to, the following embodiments.

[0085] In one embodiment, the water circuit assembly 40 also includes a water inlet air chamber 471, which is connected to the outside of the dishwasher and to the water inlet channel 41 and / or the dispensing channel 43. That is, the water inlet air chamber 471 can be configured to connect to the water inlet channel 41, or to the dispensing channel 43; it can also be configured to connect to both the water inlet channel 41 and the dispensing channel 43. By connecting the water inlet channel 41 and the dispensing channel 43 to the outside of the dishwasher 100, the air pressure inside and outside the dishwasher 100 can be balanced. During fluid flow, the problem of increased flow resistance due to inconsistent internal and external air pressure can be avoided, maintaining the stable operation of the water circuit assembly 40.

[0086] In some examples, the air inlet cavity 471 is connected to the water inlet channel 41, which can balance the air pressure in the water inlet channel 41 and prevent siphoning in the water inlet channel 41. For example, the water inlet channel 41 includes a first branch 411 and a second branch 412. When the first branch 411 generates a negative pressure relative to the second branch 412, it is connected to the outside atmosphere through the air inlet cavity, so that the air pressure of the first branch 411 is balanced, avoiding the siphoning phenomenon of water flowing back from the first branch through the second branch, and ensuring the stability of the water inlet volume.

[0087] In some examples, the water inlet air cavity 471 is connected to the dispensing channel 43, which can balance the air pressure in the dispensing channel 43 and prevent siphoning in the dispensing channel 43. In conjunction with the aforementioned embodiments, the water circuit assembly 40 has a water inlet air cavity 471, which can balance the internal and external air pressure. Specifically, the water inlet air cavity 471 is connected to the outside of the dishwasher 100 and to the first channel 431 and / or the second channel 432. For example, the water inlet air cavity 471 can be connected to the first channel 431; the water inlet air cavity 471 can be connected to the second channel 432; or the water inlet air cavity 471 can also be connected to both the first channel 431 and the second channel 432. Thus, the water inlet air cavity 471 can balance the air pressure inside and outside the water circuit assembly 40, facilitating fluid flow between the consumable dispensing module 20 and the water circuit assembly 40, reducing fluid resistance, and saving energy and protecting the environment.

[0088] In some examples, the outer wall of the water passage assembly 40 is provided with a vent 474 for the water inlet air cavity 471 to connect to the external space of the water passage assembly 40.

[0089] In the second embodiment, the integrated water circuit assembly 402 further includes a water inlet air chamber 471, which is externally connected to the water circuit assembly 40 and also connected to the water inlet channel 41. The integrated water circuit assembly 402 further includes a first one-way valve 476, which is configured to allow one-way air intake from the water inlet air chamber 471 to the water inlet channel 41. This can prevent water inlet siphoning.

[0090] The water inlet air chamber 471 is equipped with a rib 478, which blocks the first one-way valve 476 and leaves a gap between itself and the wall of the water inlet channel 41, allowing airflow from the external space to bypass the rib 478 and reach the first one-way valve 476. This prevents water from flowing out of the water inlet channel 41. Optionally, the rib 478 is located between the first one-way valve 476 and the vent 474.

[0091] In the third embodiment, the water circuit assembly 40 also has a water inlet air cavity 471, which is connected to the outside of the water circuit assembly 40, and a return cavity 472, which connects the water inlet air cavity 471 and the inner liner interface 42. The return cavity 472 is used to achieve air pressure balance in the inner liner interface 42 and the dispensing channel 43. In addition, in conjunction with the above, there is also an overflow channel 46, which connects to the inner liner interface 42 and can also achieve air pressure balance in the salt chamber module 30.

[0092] In addition, the integrated water circuit assembly 402 also has a salt cavity channel 45 for connecting the salt cavity module 30. The return cavity 472 and the water inlet air cavity 471 are respectively disposed on opposite sides of the salt cavity channel 45. A connecting channel is provided between the return cavity 472 and the water inlet air cavity 471. The connecting channel and the salt cavity channel 45 are staggered along the thickness direction of the water circuit assembly 40. Optionally, the return cavity 472 is disposed between the delivery channel 43 and the salt cavity channel 45; optionally, the water inlet air cavity 471 is disposed between the water inlet channel 41 and the salt cavity channel 45.

[0093] In the fourth embodiment, the integrated water circuit assembly 402 also has a water inlet air cavity 471, which is connected to the outside of the water circuit assembly 40. The integrated water circuit assembly 402 also has a drainage channel 49 for drainage and a drainage air cavity 473 connected to the drainage channel 49. A second one-way valve 477 is provided between the drainage air cavity 473 and the water inlet air cavity 471, and is configured to be unidirectionally conductive from the water inlet air cavity 471 to the drainage air cavity 473.

[0094] When negative pressure is generated in the upstream and downstream sections of the drain channel 49, the second one-way valve 477 opens under the suction of the negative pressure. The drain channel 49 is connected to the outside atmosphere, so that the air pressure in the drain channel 49 is balanced, preventing water from flowing back from the downstream section to the upstream section. Alternatively, without the drain pump, the water in the dishwasher 100 is discharged involuntarily from the drain pipe to the external drain pipe, avoiding abnormal water shortage inside the dishwasher 100. When the air pressure in the upstream section of the drain is higher than that in the downstream section, or when water flows into the exhaust air chamber during drainage, the second one-way valve 477 can be used to restrict the flow of water from the drain channel 49 into the water inlet air chamber 471.

[0095] In some embodiments of the present invention, the outlet of the dispensing channel 43 (or the outlet of the second channel 432) may be connected to the outlet of the overflow channel 46 and connected to the inner liner interface 42.

[0096] In conjunction with the foregoing, in some embodiments, the water circuit assembly 40 also has a brine chamber channel 45 and a resin chamber 401. The brine chamber channel 45 is connected to the resin chamber 401 and has a brine chamber interface 451 for connecting the brine chamber module 30. The brine chamber module 30 is suitable for installing or placing regeneration media such as salt, and is configured to release regeneration media such as brine into the resin chamber 401 and other structures to assist in the regeneration of the media in the resin chamber 401 and other structures, thereby facilitating the continuous softening of water quality using the resin chamber 401 and other structures.

[0097] As shown in Figures 7 and 8, in some embodiments of the present invention, the water channel assembly 40 includes a resin cavity 401 and a water channel integration component 402. The water channel integration component 402 has a first end and a second end opposite to each other, and the resin cavity 401 is connected to the first end of the water channel integration component 402. This allows the resin cavity 401 and each channel to be integrated together, and by placing the relatively large resin cavity 401 at one end of the water channel integration component 402, space utilization can be improved, facilitating the assembly of the water channel assembly 40.

[0098] Referring to Figures 1 and 7, in some embodiments, the dispensing channel 43 includes a first channel 431 and a second channel 432. One end of the first channel 431 extends to the resin cavity 401, and the other end extends to the second end of the water channel integrated assembly 402 and has a first interface 433. One end of the second channel 432 is connected to the inner liner interface 42, and the other end extends to the second end of the water channel integrated assembly 402 and has a second interface 434. By placing the first interface 433 and the second interface 434 in the same section of the water channel integrated assembly 402 and extending the first channel 431 and the second channel 432 to the resin cavity 401, the structure of the water channel assembly 40 can be further simplified, and it is convenient to connect the water channel assembly 40 to the consumable dispensing module 20, simplifying the structure of the dishwasher 100, reducing the space occupied by the water channel assembly 40, and improving space utilization.

[0099] Referring to Figures 1 and 7, in some embodiments, the water circuit assembly 40 further includes a salt cavity channel 45 for connecting the salt cavity module 30. One end of the salt cavity channel 45 extends to the resin cavity 401, and the other end extends to the second end of the water circuit integration assembly 402 and has a salt cavity interface 451. This facilitates connection to the salt cavity module 30 and allows for easy introduction of water flow from the resin cavity 401 into the salt cavity module 30, as well as backflow of water flow from the salt cavity module 30 back to the resin cavity 401, thereby facilitating resin regeneration and improving the stability of the water circuit assembly 40.

[0100] In addition, as described above, the water circuit assembly 40 also has an overflow channel 46 for connecting the salt chamber module 30. One end of the overflow channel 46 extends to the second end of the water circuit integration assembly 402 and has an overflow interface 461, while the other end connects to the inner tank interface 42. The overflow channel 46 facilitates the overflow of the salt chamber module 30, preventing water from overflowing from the dishwasher 100 and maintaining the stability of the water circuit assembly 40 and the dishwasher 100.

[0101] Referring to Figures 1 and 7, in some embodiments of the present invention, the water inlet channel 41 includes a first branch 411 and a second branch 412. The resin cavity 401 is provided with a water inlet 413. One end of the first branch 411 extends to the resin cavity 401 and connects to the water inlet 413, and the other end extends to the second end near the water channel integrated assembly 402. One end of the second branch 412 extends to the resin cavity 401, and the other end extends to the second end near the water channel integrated assembly 402 and connects to the first branch 411.

[0102] In conjunction with the foregoing, the inner liner interface 42 of this invention can be used for dispensing consumables into the inner liner 10 to complete the cleaning of tableware. Additionally, the inner liner interface 42 can also be used to handle excess water overflow from the salt chamber module 30. Furthermore, in conjunction with the aforementioned embodiments, the water inlet air chamber 471 can also be connected to the inner liner interface 42. This connection facilitates balancing the air pressure within the inner liner 10 and also allows for smooth water flow, preventing water overflow from the water system assembly 40 or the dishwasher 100.

[0103] A schematic diagram of a waterway assembly 40 according to an embodiment of the present invention is described below with reference to Figures 1 to 7.

[0104] As shown in Figures 1 to 7, the water system assembly 40 includes a water inlet channel 41, a dispensing channel 43, a brine chamber channel 45, an overflow channel 46, a drainage channel 49, a water inlet air chamber 471, and a resin chamber 401. It also includes a water inlet 413, an inner liner interface 42, a first interface 433, a second interface 434, a brine chamber interface 451, and an overflow interface 461. The resin chamber 401 is located at the lower part of the water system assembly 40, and the water inlet 413 is located at the bottom of the resin chamber 401. The water inlet channel 41 includes a first branch and a second branch. The lower end of the first branch is connected to the water inlet 413, and the upper end of the second branch is connected to the upper end of the first branch. The lower end of the second branch is not higher than the resin chamber 401 and is connected to the first reversing component 481. The water cup interface 44 is not higher than the resin chamber 401 and is connected to the first reversing component 481. The resin chamber 401 connects to the first reversing element 481 and the second reversing element 482. The dispensing channel 43 connects the second reversing element 482 and the first interface 433. The salt chamber channel 45 connects the salt chamber interface 451 and the second reversing element 482. The dispensing channel 43 connects to the second interface 434 and the inner liner interface 42. The overflow channel 46 connects to the overflow interface 461 and the inner liner interface 42. The water inlet air chamber 471 connects to the drain channel 49 and / or the inner liner interface 42. The water circuit assembly 40 is connected to a flow meter, which is used to detect the flow rate of the first branch channel.

[0105] As shown in Figure 9, the present invention also provides a dishwasher 100. According to an embodiment of the present invention, the dishwasher 100 has a washing chamber 101, in which tableware and the like can be placed, and can realize the functions of washing, drying and / or storing tableware and the like.

[0106] It also includes a consumable dispensing module 20, which is connected to the inner liner 10. The consumable dispensing module 20 is used for dispensing consumables. The consumable dispensing module 20 is suitable for installing or placing consumables and is configured to dispense consumables into the inner liner 10 to assist in the cleaning of tableware, etc.

[0107] In addition, the dishwasher 100 also includes a water circuit assembly 40 as described above. The water circuit assembly 40 is disposed on the inner tub 10. The first interface 433 and the second interface 434 are connected to the consumable dispensing module 20, and the inner tub interface 42 is connected to the internal space of the washing chamber 101. The dishwasher 100 of the present invention uses the water circuit assembly 40 to connect the consumable dispensing module 20 and the inner tub 10, so that the consumables are dissolved in water in the consumable dispensing module 20 and then dispensed into the inner tub 10. This facilitates the complete dispensing of consumables to be dispensed in the consumable dispensing module 20, avoids the consumables from condensing on the inner wall of the washing chamber 101 of the dishwasher 100, which would cause the actual amount of consumables dispensed to be inconsistent with the expected amount, and facilitates the cleaning of the dishwasher 100.

[0108] The water circuit assembly 40 is located on the inner tank 10 and is connected to the inner tank 10, the consumable dispensing module 20 and the salt chamber module 30 respectively. Water can be supplied to the inner tank 10 through the water circuit assembly 40, or water can be used to assist the consumable dispensing module 20 in dispensing consumables, or water can be used to assist the salt chamber module 30 in dispensing regeneration media, etc. The integration of the water circuit can facilitate the integration of various modules of the dishwasher 100.

[0109] In some embodiments, the water cup is connected to the bottom of the inner liner 10, and the inner liner interface 42 serves as a dispensing port connecting to the inner liner 10. This allows fluid to be dispensed into the inner liner 10 via the inner liner interface 42. Connecting the inner liner interface 42 to the inner liner 10 facilitates fluid dispensing, shortens the fluid dispensing path, and avoids energy loss during fluid flow, thus saving energy and protecting the environment. It also allows the water circuit assembly 40 to conveniently supply fluid to the inner liner 10, shortening the piping and improving the operational stability of the dishwasher 100.

[0110] The consumable dispensing module 20 and the salt chamber module 30 of this invention can be disposed in different positions within the dishwasher 100. For example, one of the consumable dispensing module 20 and the 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 the salt chamber module 30 can be adjusted according to actual needs. In addition, this invention provides some specific placement positions for the consumable dispensing module 20 and the salt chamber module 30, but this is not a limitation on the scope of protection of this invention.

[0111] In some embodiments of the present invention, the consumable dispensing module 20 is disposed outside the washing chamber 101, and at least partially disposed above the washing chamber 101. Consumables or a container for storing consumables (hereinafter referred to as a consumable box) can be placed inside the consumable dispensing module 20. When the dishwasher 100 is operating, the consumable dispensing module 20 can dispense consumables into the washing chamber 101, which are used for cleaning dishes within the dishwasher 100. To facilitate the addition of consumables or consumable boxes to the consumable dispensing module 20 and to improve the durability of consumable storage, the consumable dispensing module 20 can be disposed outside the washing chamber 101, with at least a portion of the consumable dispensing module 20 located above the washing chamber 101. Specifically, a portion of the consumable dispensing module 20 can be disposed above the washing chamber 101; alternatively, the entire consumable dispensing module 20 can be disposed above the washing chamber 101. In addition, at least a portion of the consumable dispensing module 20 is located above the washing chamber 101, which may include any point of the consumable dispensing module 20 above the washing chamber 101; or the consumable dispensing module 20 may be located above the portion of the washing chamber 101 that is vertically opposite to the consumable dispensing module 20.

[0112] In addition, the integrated water circuit assembly has multiple interfaces at its upper end, and the dishwasher also includes multiple water guide pipes corresponding to each of the multiple interfaces. The water guide pipes extend in the vertical direction and their lower ends are connected to the corresponding interfaces.

[0113] The upper end of a portion of the multiple water pipes is connected to the consumable dispensing module; and / or, the dishwasher also includes a salt chamber module, the upper end of another portion of the multiple water pipes being connected to the salt chamber module.

[0114] Specifically, in addition to the foregoing, the upper end of the integrated water circuit component in this invention is provided with a brine cavity interface 451, an overflow interface 461, a first interface 433, and a second interface 434. The brine cavity interface 451, overflow interface 461, first interface 433, and second interface 434 can be located at the upper end of the integrated water circuit component. Above the inner liner 10, a consumable dispensing module and a brine cavity module are provided. A first water guide pipe extending in the vertical direction is provided between the first interface 433 and the consumable dispensing module. A second water guide pipe extending in the vertical direction is provided between the second interface 434 and the consumable dispensing module. A third water guide pipe extending in the vertical direction is provided between the overflow interface 461 and the brine cavity module. A fourth water guide pipe extending in the vertical direction is provided between the brine cavity interface 451 and the brine cavity module. The first water guide pipe, the second water guide pipe, the third water guide pipe, and the fourth water guide pipe can be arranged side by side.

[0115] The water system assembly 40 is equipped with a dispensing interface, which is connected to the consumable dispensing module 20. Positioning the consumable dispensing module 20 outside the washing chamber 101 avoids the influence of water, steam, and high temperatures within the washing chamber 101 on the consumables stored in the module, ensuring stable storage of the consumables. Furthermore, positioning the consumable dispensing module 20 above the washing chamber 101 facilitates user access to add consumables. Specifically, by placing the consumable dispensing module 20 at the top of the dishwasher 100, its higher position allows users to add consumables without bending over. This also makes adding consumables to the module 20 more convenient than placing it at the front or side of the dishwasher 100.

[0116] The consumable dispensing module 20 may include an automatic dispensing module. For example, by setting up a pumping component and a consumable box, the pumping component pumps the consumables out of the consumable box, thereby achieving automatic dispensing of consumables. The automatic dispensing of consumables can be controlled by the pumping component, thus enabling multiple dispensings from a single addition. The consumable dispensing module 20 may also include a manual dispensing module. For example, a manual dispensing chamber is provided, allowing users to manually add consumables into the chamber. Water flows through the manual dispensing chamber to dissolve the manually dispensed consumables and dispense them into the dishwasher 100. In addition, the consumable dispensing module 20 of this invention can store a certain amount of consumables and dispense them in multiple batches; it can also be set up so that users dispense and use them once. Furthermore, the consumables in this invention can be liquid consumables, solid consumables, granular consumables, etc., and the consumable box is a container containing consumables.

[0117] As shown in Figure 9, the consumable dispensing module 20 is configured as a push-pull drawer structure. Specifically, the inner liner 10 may include a housing with a storage space inside. The consumable dispensing module 20 can be placed in this storage space, which extends front to back, and has a drawer opening at its front end. The consumable dispensing module 20 is inserted into the storage space and can be pushed and pulled in the front-back direction. The consumable dispensing module 20 has a storage space, and the drawer opening can be partially pulled out. Placing the consumable dispensing module 20 inside the housing provides protection for it and facilitates connection between the module and the water system, allowing consumables from the module to be dispensed into the dishwasher 100 for cleaning tableware, etc. The consumable dispensing module 20 can be pushed and pulled into the storage space, and its top is open. In other words, the consumable dispensing module 20 is designed as a drawer-type structure. This allows the opening to be exposed when the module is pulled out, enabling the addition of consumables or consumable boxes (containers containing consumables) to the module through this opening, thus facilitating user operation. The drawer-type structure of the consumable dispensing module 20 allows for easy addition of consumables by pulling it out and pushing it back into the housing. This convenient and quick operation enables rapid installation or replacement of consumables. Furthermore, the fact that the consumable dispensing module 20 is pushed back into the housing during dishwasher 100 operation reduces the space occupied by the dishwasher 100, optimizing space utilization.

[0118] The consumable dispensing module 20 has an inlet and an outlet. A first interface 433 connects to the inlet, and a second interface 434 connects to the outlet. Water can enter the consumable dispensing module 20 through the first interface 433 and the inlet, dissolve the consumables within the module, and then flow back to the water circuit assembly 40 through the outlet and the second interface 434. From there, water enters the inner tank 10 and participates in the dishwashing process of the dishwasher 100. Similarly, the consumable dispensing module 20 can also be configured with an inlet and an outlet, allowing fluid to flow in and out through a single opening.

[0119] As shown in Figure 9, in some embodiments of the present invention, the dishwasher 100 further includes a salt chamber module 30. The salt chamber module 30 is disposed on the inner tub 10, outside the washing chamber 101, and at least partially above the washing chamber 101. Salt can be placed in the salt chamber module 30, and after the resin has been used for a period of time, brine needs to be introduced for regeneration. Brine can be introduced into the resin chamber 401 through the salt chamber module 30. To facilitate the addition of regeneration media such as salt to the salt chamber module 30, the salt chamber module 30 can be disposed outside the washing chamber 101, with at least a portion of the salt chamber module 30 located above the washing chamber 101. Specifically, a portion of the salt chamber module 30 can be located above the washing chamber 101; alternatively, the entire salt chamber module 30 can be located above the washing chamber 101. Additionally, at least a portion of the salt chamber module 30 is located above the washing chamber 101, which may include the salt chamber module 30 being higher than any part of the washing chamber 101; or the salt chamber module 30 being higher than the portion of the washing chamber 101 that is vertically opposite to the salt chamber module 30.

[0120] The salt chamber interface 451 is connected to the salt chamber module 30. Positioning the salt chamber module 30 outside the washing chamber 101 avoids the influence of water, steam, and high temperatures within the washing chamber 101 on the regeneration medium stored in the salt chamber module 30, facilitating stable storage of the regeneration medium. Positioning the salt chamber module 30 above the washing chamber 101 makes it convenient for users to add salt and other media into it. Specifically, by placing the salt chamber module 30 at the top of the dishwasher 100, its higher position allows users to add regeneration medium without bending over. Furthermore, compared to placing the salt chamber module 30 at the front or side of the dishwasher 100, adding regeneration medium to the salt chamber module 30 is much more convenient.

[0121] As shown in Figure 9, the salt chamber module 30 is configured as a push-pull drawer structure. Specifically, the inner liner 10 may include a shell with a storage space inside. The salt chamber module 30 can be placed in this storage space, which extends front to back, and has a drawer opening at its front end. The salt chamber module 30 is inserted into the storage space and can be pushed and pulled in the front-back direction. The salt chamber module 30 has storage space, and the drawer opening can be partially pulled out. Placing the salt chamber module 30 inside the shell provides protection for it and facilitates connection between the salt chamber module 30 and the water system, allowing consumables inside the salt chamber module 30 to be placed in the dishwasher 100 for cleaning tableware, etc. The salt chamber module 30 can be pushed and pulled into the storage space, and its top is open. In other words, by configuring the salt chamber module 30 as a drawer, the opening is exposed when the salt chamber module 30 is pulled out, allowing the addition of regeneration media through this opening, thus facilitating user operation. The salt chamber module 30 adopts a drawer-type structure. It can be pulled out to add regeneration media and then pushed back into the housing for convenient media dispensing. This convenient and quick operation allows for rapid installation or replacement of consumables. Furthermore, the fact that the salt chamber module 30 is pushed into the housing during dishwasher 100 operation reduces the space occupied by the dishwasher 100, optimizing space utilization. Additionally, the housing accommodating the salt chamber module 30 and the housing accommodating the consumable dispensing module 20 can be the same housing or different housings.

[0122] In conjunction with the foregoing, similar to the consumable dispensing module 20, the brine chamber module 30 may also have an inlet and an outlet. The brine chamber interface 451 may include two interfaces respectively connected to the inlet and outlet of the brine chamber module 30. Furthermore, the brine chamber module 30 has inlets and outlets, and the brine chamber interface 451 is connected to these inlets and outlets. That is, water flows into the brine chamber module 30 through its inlets and outlets, dissolves the salts to form brine, and then flows back into the water circuit assembly 40 and the resin chamber 401 to regenerate the resin.

[0123] 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 401.

[0124] The consumable dispensing module 20 and the salt chamber module 30 can be arranged side-by-side above the washing chamber 101. 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.

[0125] At least a portion of the water circuit assembly 40 is located on the outer side wall of the washing chamber 101, while the dispensing port and salt chamber port 451 are located on the upper part of the water circuit assembly 40, with their axes extending vertically. This design improves the space utilization of the dishwasher 100. The integrated water circuit can cover a large area while being relatively thin. Furthermore, the integrated water circuit can be hidden inside the dishwasher 100, thus minimizing its impact on the overall structure and operation and maintenance of the dishwasher 100, while significantly improving its space utilization. This optimizes the structure and performance of the dishwasher 100.

[0126] In some embodiments, the integrated water channel assembly is a plate-like structure disposed on the side wall of the inner liner 10.

[0127] Optionally, the first interface 433, the second inlet interface, the salt chamber interface 451, and the overflow interface 461 are arranged side by side. This facilitates the connection of the water circuit assembly 40 to the salt chamber module 30 and the consumable dispensing module 20, simplifies the assembly process of the dishwasher 100, and reduces costs.

[0128] In some embodiments, the water circuit assembly 40 includes an integrated water circuit component 402 and a resin chamber 401. The resin chamber 401 and the integrated water circuit component 402 can be connected into a single structure. The integrated water circuit component 402 is installed on the outer side wall of the inner tank. The upper end of the integrated water circuit component 402 has an interface for connecting the consumable dispensing module 20 and the salt chamber module 30, and the lower end is connected to the resin chamber 401, which contains a resin chamber 401. The integrated water circuit component 402 allows fluid to flow into the consumable dispensing module 20 and the salt chamber module 30, while the resin chamber 401 softens the fluid, thereby optimizing the dishwashing effect of the dishwasher 100 and improving the performance of the dishwasher 100.

[0129] Optionally, the consumable dispensing module 20 is at least partially located above the inner tank 10, and is situated above the integrated water system assembly to facilitate the dispensing of consumables.

[0130] In some embodiments, at least a portion of the resin cavity 401 is located below the inner liner 10. By placing the resin cavity 401 below the inner liner 10, the space occupied by the resin cavity 401 can be reduced, the space below the inner liner 10 can be fully utilized, and the space utilization rate can be improved. In addition, the lower placement of the resin cavity 401 can, to some extent, lower the center of gravity of the dishwasher 100, which is beneficial to improving the stability of the dishwasher 100.

[0131] As shown in Figure 9, 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.
