The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figure 1 According to the water circuit assembly 40 of the dishwasher 100 of the embodiment of the utility model, the dishwasher 100 includes an inner tank 10, a water cup (not shown in the figure), a salt chamber module 30 and a consumables delivery module 20, wherein tableware and the like can be placed in the inner tank 10, and functions such as washing, drying and / or storing the tableware and the like can be realized; the water cup is connected to the bottom of the inner tank; the salt chamber module 30 is used for storing salt (storing regeneration salt), and when the medium in the resin chamber needs to be regenerated, the regeneration salt in the salt chamber can be passed to the resin chamber 42 for medium regeneration. The consumables delivery module 20 is used for storing and delivering consumables, and the consumables delivery module 20 is suitable for installing or placing consumables, and is configured to be used for delivering consumables into the inner tank 10 to assist in the cleaning of tableware and the like.

[0044] Specifically, the water channel assembly 40 has a water inlet channel 41, a salt chamber channel 45, a resin chamber 42, a delivery channel 43 and a delivery port 441.

[0045] In addition, the water channel assembly 40 includes a switching component 48, which is respectively connected to the water inlet channel 41, the salt chamber channel 45, the resin chamber 42, the delivery channel 43 and the delivery port 441. The switching component 48 is used to guide the fluid from the water inlet channel 41 into the salt chamber channel 45, wherein the salt chamber channel 45 can deliver the fluid to the salt chamber module 30; the switching component 48 is also used to guide the fluid of the salt chamber module 30 into the resin chamber 42 through the salt chamber channel 45; the switching component 48 is also used to guide the fluid from the resin chamber 42 into the delivery channel 43 to be delivered to the consumable delivery module 20; the switching component 48 is also used to deliver the fluid of the consumable delivery module 20 to the delivery port 441 through the delivery channel 43.

[0046] When resin regeneration is required, the water flow entering through the water 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 is dissolved in water after soaking. The switching component 48 is also used to connect the salt chamber channel 45 with the resin chamber 42. The salt water in the salt chamber module 30 can flow into the resin chamber 42 through the salt chamber channel 45 to achieve resin regeneration in the resin chamber 42. The delivery channel 43 can guide the fluid to pass into the consumable delivery module 20 to flush or dissolve the consumables in the consumable delivery module 20; the delivery channel 43 can also guide the fluid from the consumable delivery module 20 to the delivery port 441, and finally delivered into the inner liner 10 through the delivery port 441 to complete the delivery of consumables.

[0047] The water circuit assembly 40 of the dishwasher 100 according to the embodiment of the utility model has a salt chamber channel 45, which can be used to connect the salt chamber module 30, so that water can be passed to the salt chamber module 30 through the water circuit assembly 40 to dissolve the salt in the salt chamber module 30, and the salt water dissolved in the salt chamber module 30 can also be passed to the resin chamber 42 for regeneration of the resin in the resin chamber 42. The structure of the water circuit assembly 40 is simplified, the integration of the water circuit assembly 40 is improved, and the salt chamber module 30 is separated from the water circuit assembly 40, so that the salt chamber module 30 can be conveniently placed in a position suitable for adding salt, simplifying the operation steps of adding salt for users.

[0048] The water circuit assembly 40 in the present invention can have multiple working modes. For example, the water circuit assembly 40 can have a first washing water supply mode, a second washing water supply mode, a salt chamber water supply mode and / or a resin regeneration mode.

[0049] In the first washing water supply mode, the water inlet channel 41, the resin chamber 42 and the delivery port 441 are connected. The water flows into the resin chamber 42 through the water inlet channel 41, and enters the delivery port 441 after being softened by the resin chamber 42, so that the softened water is passed into the inner tank 10. The water enters the water inlet channel 41 through the water inlet 413, and then enters the resin chamber 42 for softening treatment, and after softening treatment, it flows to the delivery port 441 or the consumable delivery module 20, and is sent to the inner tank 10 for washing;

[0050] In the second washing water supply mode, the water inlet channel 41, the resin chamber 42, the delivery channel 43 and the delivery port 441 are connected. The water flows into the resin chamber 42 through the water inlet channel 41, and enters the delivery channel 43 after being softened by the resin chamber 42, and flows into the consumable delivery module 20 through the delivery channel 43, and flows into the delivery port 441 after passing through the consumable delivery module 20, so that the softened water flows into the inner tank 10.

[0051] In the water supply mode of the salt chamber module 30, the water inlet channel 41, the resin chamber and the salt chamber channel 45 are connected. The water flow can enter the salt chamber channel 45 through the water inlet channel 41, and can be introduced into the salt chamber module 30 through the salt chamber channel 45, so as to dissolve the salt in the salt chamber module 30 in water and prepare for resin regeneration. Water enters the water inlet channel 41 through the water inlet 413, and enters the salt chamber module 30 through the salt chamber channel 45, so as to dissolve the salt stored in the salt chamber module 30;

[0052] In the resin regeneration mode, the salt chamber channel 45 is connected to the resin chamber 42. The salt water in the salt chamber module 30 can flow into the resin chamber 42 through the salt chamber channel 45, thereby achieving resin regeneration in the resin chamber 42. After the resin regeneration is completed, the water quality can be better softened in the first working mode to improve the washing effect. The salt water in the salt chamber module 30 flows into the salt chamber channel 45 through the salt chamber interface 451, and is sent to the resin chamber 42 through the salt chamber channel 45 to achieve resin regeneration.

[0053] Of course, the waterway assembly 40 in the present invention can realize one or more of the above-mentioned working modes.

[0054] In order to implement the switching of the switching component 48 between different working modes, the present utility model provides some implementation methods.

[0055] In some embodiments, the water inlet channel 41 is connected to the resin chamber 42 , and the switching assembly 48 is configured to control the water inlet channel 41 and the salt chamber channel 45 to be connected or disconnected, and control the resin chamber 42 and the injection port 441 to be connected or disconnected.

[0056] Specifically, when the switching component 48 is configured to control the water inlet channel 41 to be disconnected from the salt chamber channel 45 and the resin chamber 42 to be connected to the delivery port 441, water can flow from the water inlet channel 41 to the resin chamber 42, and then flow to the delivery port 441 after passing through the resin chamber 42, and the switching component 48 is in the first washing water supply mode;

[0057] When the switching component 48 is configured to control the water inlet channel 41 to be connected with the salt chamber channel 45 and the resin chamber 42 to be disconnected from the delivery port 441, water can flow from the water inlet channel 41 into the resin chamber 42 and the salt chamber channel 45, wherein, since the resin chamber 42 is disconnected from the delivery port 441, the water flow entering the resin chamber 42 will be cut off, so the water flow of the water inlet channel 41 can only flow to the salt chamber channel 45, and then flow into the salt chamber module 30 after passing through the salt chamber channel 45, and the switching component 48 is in the salt chamber water supply mode;

[0058] When the switching component 48 is configured as follows: the salt chamber channel 45 is connected to the resin chamber 42, and the resin chamber 42 is connected to the injection port 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 resin regeneration in the resin chamber 42, and the switching component 48 is in the resin regeneration mode.

[0059] In still other embodiments, the water inlet channel 41 is connected to the resin chamber 42, the reflux port 435 of the delivery channel 43 is connected to the delivery port 441, and the switching component 48 is configured to control the connection or disconnection of the water inlet channel 41 and the salt chamber channel 45, the connection or disconnection of the resin chamber 42 and the delivery port 441, and the connection or disconnection of the resin chamber 42 and the water injection port 432 of the delivery channel 43.

[0060] like Figure 2 , when the switching component 48 is configured to: control the water inlet channel 41 to be disconnected from the salt chamber channel 45, the resin chamber 42 to be connected to the delivery port 441, and the resin chamber 42 and the water injection port 432 of the delivery channel 43 to be disconnected, water can flow from the water inlet channel 41 to the resin chamber 42, and then flow into the delivery port 441 after passing through the resin chamber 42, and the switching component 48 is in the first washing water supply mode;

[0061] like Figure 4 , when the switching component 48 is configured to: control the water inlet channel 41 to be connected with the salt chamber channel 45, the resin chamber 42 to be disconnected from the delivery port 441, and the resin chamber 42 to be disconnected from the water injection port 432 of the delivery channel 43, water can flow from the water inlet channel 41 to the resin chamber 42 and the salt chamber channel 45, wherein, since the resin chamber 42 is disconnected from the delivery port 441 and the resin chamber 42 is disconnected from the delivery channel 43, the water flow entering the resin chamber 42 will be cut off, so the water flow of the water inlet channel 41 can only flow to the salt chamber channel 45, and after passing through the salt chamber channel 45, it is passed into the salt chamber module 30, and the switching component 48 is in the salt chamber water supply mode;

[0062] like Figure 5 , the switch component 48 is configured to: control the salt chamber channel 45 to be connected to the resin chamber 42, and the resin chamber 42 to be connected to the delivery port 441, the salt water in the salt chamber module 30 will flow into the resin chamber 42 through the salt chamber channel 45, so as to achieve the resin regeneration in the resin chamber 42, the switch component 48 is in the resin regeneration mode, after the salt water fills the resin chamber 42, the resin chamber 42 is disconnected from the delivery port 441, so that the salt water and the resin are fully soaked and replaced, and then the resin chamber 42 is connected to the delivery port 441, so that the waste water after the regeneration is discharged from the resin chamber. Thereafter, it can be switched to the first washing water supply mode, and the resin chamber can be flushed and discharged by passing water through the resin chamber 42.

[0063] like Figure 3 When the switching component 48 is configured as follows: controlling the water inlet channel 41 to be disconnected from the salt chamber channel 45, the resin chamber 42 to be disconnected from the delivery port, and the resin chamber 42 to be connected to the delivery channel 43, water can flow from the water inlet channel 41 to the resin chamber 42, wherein, since the resin chamber 42 is disconnected from the delivery port 441 and the resin chamber 42 is connected to the delivery channel 43, the water flow entering the resin chamber 42 will flow into the delivery channel 43, so the water flow of the water inlet channel 41 will flow to the delivery channel 43, and after passing through the delivery channel 43, it will be passed into the consumable delivery module 20, and then the consumables in the consumable delivery module 20 will be dissolved or flushed, at this time, the reflux port 435 of the delivery channel 43 is connected with the delivery ports 441441, and the consumables in the consumable delivery module 20 are passed into the delivery port 441 and delivered into the inner tank 10, and the switching component 48 is in the second washing water supply mode.

[0064] In the above-mentioned embodiment, the switching component 48 can control the connection or disconnection of the resin chamber 42 and the water injection port 432 of the delivery channel 43. Therefore, the switching component 48 can be configured to be unidirectionally connected from the resin chamber 42 to the water injection port 432 of the delivery channel 43, and the opening pressure is not less than a predetermined threshold. In this way, when the water inlet channel 41 and the salt chamber channel 45 are connected and / or the resin chamber 42 and the delivery port 441 are connected, since the water flow can flow into the salt chamber channel 45 or the delivery port 441, the opening pressure will not be reached between the resin chamber 42 and the delivery channel 43, and the resin chamber 42 and the delivery channel 43 are disconnected; when the water inlet channel 41 and the salt chamber channel 45 are disconnected, and the resin chamber 42 and the delivery port 441 are disconnected, the water flow can only flow to the delivery channel 43, the opening pressure will be reached between the resin chamber 42 and the delivery channel 43, and the resin chamber 42 and the water injection port 432 of the delivery channel 43 are connected.

[0065] In some embodiments, the switching assembly 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 salt 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 unidirectionally conduct the water injection port 432 from the resin chamber 42 to the delivery channel 43, and the opening pressure is not less than a predetermined threshold. Among them, any one of the first control valve 481, the second control valve 482, and the third control valve 483 can be set as a solenoid valve.

[0066] In combination with the above embodiments, Figure 2 , when the first control valve 481 is closed, the second control valve 482 is opened, and the third control valve 483 has not reached the opening pressure, the switching component 48 is in the first washing water supply mode; 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 the opening pressure, the switching component 48 is in the salt chamber water supply mode; Figure 5 , when the first control valve 481 is opened, the second control valve 482 is opened, the third control valve 483 has not reached the opening pressure, and the water inlet 413 of the water inlet channel 41 is no longer flowing with water, the switching component 48 is in the resin regeneration mode; Figure 3 When 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.

[0067] In some embodiments of the present invention, the delivery port 441 includes a water cup interface, and the water cup interface is used to connect the water cup of the inner liner 10.

[0068] like Figure 1 and Figure 6In some embodiments of the present invention, the water channel 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 will flow into the overflow channel 46 through the overflow interface 461, and then flow into the delivery port 441 through the overflow channel 46, thereby sending out the excess fluid in the salt chamber module 30. Among them, the overflowing fluid can be discharged into the inner tank 10 through the delivery port 441, and the fluid entering the inner tank 10 is discharged through the drainage channel 403, thereby avoiding the problem that the fluid water level and flow rate in the salt chamber module 30 are too large, resulting in unstable operation of the dishwasher 100 or fluid overflow in the dishwasher 100. The overflow channel 46 is connected to the water cup interface, and the fluid overflowing from the salt chamber module 30 can be passed into the water cup, which is convenient for the discharge of the overflow fluid and avoids the generation of erosion marks on the inner wall of the inner tank, thereby extending the service life of the inner tank and facilitating the cleaning of the dishwasher 100.

[0069] In combination with the above embodiments, Figure 1 The delivery channel 43 may include a first channel 431, a second channel 434 and a third channel. The upper end of the waterway 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 or disconnected with the resin chamber 42, and the upper end 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 is connected to the lower end of the third channel. The lower end of the third channel is connected to the water cup interface, and the lower end of the overflow channel 46 is connected to the third channel and connected to the water cup interface through the third channel. Therefore, water can be supplied to the consumable delivery module 20 through the first channel 431, and the water and consumables in the consumable delivery module 20 are passed to the delivery port 441 through the second channel 434, so that the delivery of consumables can be facilitated. As mentioned above, the water introduced into the water inlet 413 can be introduced into the salt chamber module 30 for dissolving the salt, and the salt can be brought 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 amount of water introduced, an overflow structure is also provided in the utility model, so that when the amount of water introduced into the salt chamber module 30 is too high, overflow can be achieved through the overflow structure.

[0070] The upper end of the water channel 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 is selectively connected or disconnected with the resin chamber 42. In some embodiments of the utility model, the channel in the salt chamber channel 45 for supplying water to the salt chamber module 30 and the channel for supplying water from the salt chamber module 30 to the resin chamber 42 can be one channel or two channels.

[0071] In combination with the above, the salt chamber interface 451, the overflow interface 461, the first interface 433 and the 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 material delivery module 20, simplifies the structure of the water circuit assembly 40, facilitates the connection of the water circuit assembly 40 with other components, and improves the stability of the dishwasher 100.

[0072] The utility model is provided with a water channel assembly 40, and water can be supplied to the inner tank 10, the consumables delivery module 20 and the salt chamber module 30 through the water channel assembly 40, so that the water channel supplying water to the inner tank, the water channel supplying water to the consumables delivery module 20 and the water channel supplying water to the salt chamber module 30 are integrated together, realizing the modular design of the dishwasher 100, which can effectively improve the assembly efficiency of the dishwasher 100. In addition, the water channel is integrated into the water channel assembly 40, which can reduce the water channel joints in the dishwasher 100 and reduce the possibility of joint leakage, thereby optimizing the stability of the dishwasher 100. At the same time, through the modular design, faults can be discovered and repaired in a timely manner, so that the maintenance of the dishwasher 100 can be facilitated.

[0073] During the process of adding consumables and operating the dishwasher 100, the problem of inconsistent internal and external pressure differences is prone to occur. For example, the air pressure in the water circuit assembly 40 is inconsistent with the external air pressure; or the air pressure in the inner tank 10 is inconsistent with the external air pressure, etc. For this reason, an air cavity 47 is provided in the utility model, which is connected to the outside of the dishwasher 100 to balance the air pressure.

[0074] like Figure 1 , Figure 7 and Figure 8 In some embodiments of the present invention, the waterway assembly 40 further has an air cavity 47, which is in communication with the outside of the dishwasher 100. The air cavity 47 may have a water inlet vent 4705 and a delivery vent 4706. The water inlet vent 4705 is in communication with the water inlet channel 41, and the delivery vent 4706 is in communication with the delivery channel 43. In other words, the air cavity 47 may be arranged to be in communication with the water inlet channel 41; it may also be arranged to be in communication with the delivery channel 43; it may also be arranged to be in communication with both the water inlet channel 41 and the delivery channel 43, and so on. The air pressure inside and outside the dishwasher 100 can be balanced, and during the fluid circulation process, the problem of increased flow resistance caused by inconsistent air pressure inside and outside can be avoided, thereby maintaining the stable operation of the waterway assembly 40.

[0075] In combination with the above-mentioned embodiment, the water circuit assembly 40 has an air cavity 47, and the air pressure inside and outside can be balanced through the air cavity 47. 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 cavity vent connected to the salt cavity channel 45. Therefore, the air pressure inside and outside the water circuit assembly 40 can be balanced through the air cavity 47, which facilitates the water flow from the water inlet 413 to the resin cavity 42, and facilitates the water flow from the resin cavity 42 to the first interface 433, etc., thereby reducing fluid resistance and saving energy and protecting the environment.

[0076] like Figure 1 , Figure 7 and Figure 8 In some embodiments of the present invention, the air cavity 47 includes a first cavity 4701 and a second cavity 4702, the first cavity 4701 and the second cavity 4702 are respectively arranged on opposite sides of the salt cavity channel 45, the first cavity 4701 has an inner tank interface 442, the water inlet channel 41 has a water inlet vent 4705 that can communicate with the second cavity 4702, a connecting channel 4708 is arranged 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 channel assembly 40. In this way, the air pressure balance between the water inlet channel 41 and the inner tank can be achieved, and the stability of the operation of the dishwasher 100 can be improved.

[0077] Alternatively, if Figure 1 , Figure 7 and Figure 8 The water channel assembly 40 also has a delivery channel 43 for connecting the consumable delivery module 20. The first cavity 4701 is provided between the delivery channel 43 and the salt cavity channel 45. The delivery channel 43 has a delivery vent 4706 connected to the first cavity 4701. Thus, the air pressure balance of the delivery channel 43 can be achieved, and the delivery channel 43 can be used to balance the air pressure in the inner tank, thereby improving the operating stability of the dishwasher 100.

[0078] Alternatively, if Figure 1 , Figure 7 and Figure 8 The air cavity 47 also includes a third cavity 4703, a water inlet vent 4705 is connected to the third cavity 4703, a water inlet check valve 471 is provided between the second cavity 4702 and the third cavity 4703, and is configured to be unidirectionally connected from the second cavity 4702 to the third cavity 4703. Through the cooperation of the second cavity 4702 and the third cavity 4703, the air pressure balance of the water inlet channel 41 can be achieved. When the air pressure of the water inlet channel 41 is low, air can be introduced into the water inlet channel 41 from the inner tank, the delivery channel 43, etc. to balance the air pressure of the water inlet channel 41; when the air pressure of the water inlet channel 41 is high or water flows into the third cavity 4703, the water inlet check valve 471 can be used to limit the water flow into the second cavity 4702.

[0079] Alternatively, if Figure 1 , Figure 7 and Figure 8 The waterway assembly 40 also has a drainage channel 403 for drainage, the air cavity 47 also includes a fourth cavity 4704, the drainage channel 403 has a drainage vent 4707 connected to the fourth cavity 4704, and a drainage check valve 472 is provided between the second cavity 4702 and the fourth cavity 4704, and is configured to be unidirectional from the second cavity 4702 to the fourth cavity 4704. Through the cooperation of the second cavity 4702 and the fourth cavity 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 tank, the delivery 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 cavity 4704, the drainage check valve 472 can be used to limit the water flow into the second cavity 4702.

[0080] like Figure 1 , Fig.10 as well as Fig.11 In some embodiments of the present invention, the waterway assembly 40 includes a cavity portion 401 and an integrated waterway component 402, the integrated waterway 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 waterway component 402, and a resin cavity 42 is provided in the cavity portion 401. Thus, the resin cavity 42 and each channel can be integrated together, and the cavity portion 401 with a larger volume is provided at one end of the integrated waterway component 402, which can improve the utilization of space and facilitate the assembly of the waterway assembly 40. In addition, the water inlet 413 of the water inlet channel 41, the resin cavity 42, the water cup interface and the switching component 48 are provided on the cavity portion 401.

[0081] Please refer to the attached Figures 1 to 12 A schematic diagram of a waterway assembly 40 according to an embodiment of the present invention is described.

[0082] like Figure 1As shown, the water circuit assembly 40 includes a water inlet channel 41, a delivery 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 arranged at the lower part of the water circuit assembly 40, and the water inlet 413 is arranged 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 one 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 a middle channel, which is connected to the lower end of the resin cavity 42 and extends upward from the other end of the resin cavity 42 along 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 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 extends to connect to the water cup interface. The water cup interface can be set at the upper part of the resin cavity 42.

[0083] like Figure 1 The water channel 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, wherein the second channel 434 includes a first part and a second part, the first part and the overflow channel 46 are arranged above the second part and connected to the second part, and the upper end of the second part has a delivery vent 4706 connected to the air cavity 47.

[0084] In some embodiments of the present invention, the following working methods are included:

[0085] like Figure 2 , pre-wash water inlet stage: when the first control valve 481 is closed, the second control valve 482 is opened, 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 flow from the water inlet channel 41 into the resin chamber 42, and after passing through the resin chamber 42, into the delivery port 441.

[0086] like Figure 3, main wash and rinsing water inlet stage: 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 be passed from the water inlet channel 41 to the resin chamber 42. Among them, since the resin chamber 42 is disconnected from the delivery port 441 and the resin chamber 42 is connected to the delivery channel 43, the water flow entering the resin chamber 42 will flow into the delivery channel 43. Therefore, the water flow of the water inlet channel 41 will pass through the delivery channel 43, and after passing through the delivery channel 43, it will pass into the consumable delivery module 20, and then the consumables in the consumable delivery module 20 will be dissolved or flushed to pass the consumables in the consumable delivery module 20 into the delivery port 441.

[0087] like Figure 4 , salt chamber water inlet stage: when the first control valve 481 is opened, 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 salt chamber water supply mode, and the water flow can flow from the water inlet channel 41 into the resin chamber 42 and the salt chamber channel 45, wherein, since the resin chamber 42 is disconnected from the delivery port 441 and the resin chamber 42 is disconnected from the delivery channel 43, the water flow entering the resin chamber 42 will be intercepted, so the water flow of the water inlet channel 41 can only flow to the salt chamber channel 45, and after passing through the salt chamber channel 45, it is passed into the salt chamber module 30.

[0088] like Figure 5 , regeneration stage; when the first control valve 481 is opened, the second control valve 482 is opened, and the third control valve 483 has not reached the opening pressure, and the water inlet 413 of the water inlet channel 41 is no longer inflowing water, the switching component 48 is in the resin regeneration mode, and the brine in the salt chamber module 30 will flow into the resin chamber 42 through the salt chamber channel 45. After the brine fills the resin chamber 42, the resin chamber 42 is disconnected from the injection port 441, so that the brine and the resin are fully immersed and replaced, thereby realizing the resin regeneration in the resin chamber 42, and then the resin chamber 42 can be connected to the injection port 441 to realize the discharge of the waste water after the regeneration is completed from the resin chamber. After that, it can be switched to the first washing water supply mode, and the resin chamber can be flushed and discharged by passing water through the resin chamber 42.

[0089] like Figure 6 Overflow reflux: At this time, the water circuit assembly 40 may be in a fault state, water may flow through the first control valve 481 and the second control valve 482 or no water may flow through, and the fluid in the salt chamber module 30 flows back to the overflow channel 46 and flows to the water cup interface after passing through the overflow channel 46.

[0090] like Fig.12The utility model also provides a dishwasher 100. The dishwasher 100 according to the embodiment of the utility model includes an inner tank 10, in which tableware and the like can be placed, and the tableware and the like can be washed, dried and / or stored. The dishwasher 100 also includes a salt chamber module 30, which is connected to the inner tank 10. The salt chamber module 30 is used to store regeneration salt. When resin regeneration is required, the regeneration salt in the salt chamber can be passed to the resin chamber 42 for resin regeneration. The dishwasher 100 also includes a waterway assembly 40, which is arranged on the inner tank 10, the salt chamber channel 45 is connected to the salt chamber module 30, and the delivery port 441 is connected to the internal space of the inner tank 10. The dishwasher 100 of the utility model uses the waterway assembly 40 to connect the salt chamber module 30, pass water to the salt chamber module 30, and is used to dissolve the salt in the salt chamber module 30. The salt water dissolved in the salt chamber module 30 can also be passed to the resin chamber 42 for resin regeneration in the resin chamber 42. The structure of the water circuit assembly 40 is simplified, the integration of the water circuit assembly 40 is improved, and the salt chamber module 30 is separated from the water circuit assembly 40, so that the salt chamber module 30 can be conveniently placed in a position suitable for adding salt, simplifying the user's salt adding operation steps.

[0091] like Fig.12 In some embodiments of the utility model, the salt chamber module 30 is arranged outside the inner tank 10, and at least part of it is arranged above the inner tank 10. Salt can be put into the salt chamber module 30, and after the resin has been used for a period of time, it needs to be regenerated by passing salt water, and salt water can be passed into the resin chamber 42 through the salt chamber module 30. It can avoid the influence of water, steam, high temperature, etc. in the inner tank 10 on the regeneration medium stored in the salt chamber module 30, and facilitate the stable storage of the regeneration medium in the salt chamber module 30. The salt chamber module 30 is arranged above the inner tank 10, which can facilitate the user to add salt and other media into the salt chamber module 30. Specifically, the salt chamber module 30 is arranged on the upper part of the dishwasher 100, and the position of the salt chamber module 30 is relatively high. The user does not need to bend down to complete the addition of the regeneration medium to the salt chamber module 30. At the same time, compared with the salt chamber module 30 being arranged in front or on the side of the dishwasher 100, it is more convenient to add the regeneration medium to the salt chamber module 30.

[0092] In combination 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 the 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 the outlet, that is, water flows into the salt chamber module 30 through the inlet and outlet of the salt chamber module 30, and dissolves the salt to form brine, and then flows back to the water circuit assembly 40 and the resin chamber 42 to achieve the regeneration of the resin.

[0093] In order to facilitate the introduction of the regeneration medium into the salt chamber module 30, the salt chamber module 30 also has an overflow port. When the fluid introduced into the salt chamber module 30 is excessive, the fluid can be sent out through the overflow port. The overflow interface 461 is connected to the overflow port. In combination with the above, especially when the salt chamber module 30 realizes the inflow and outflow of fluid only through the inlet and outlet, the overflow port can be set to avoid excessive flow into the salt chamber module 30, which affects the regeneration effect of the resin chamber 42.

[0094] In addition, the dishwasher 100 also includes a consumables delivery module 20, which is connected to the inner tank 10 and is used for delivering consumables. The consumables delivery module 20 is suitable for installing or placing consumables and is configured to deliver consumables into the inner tank 10 to assist in cleaning tableware, etc.

[0095] The consumables delivery module 20 and the salt chamber module 30 in the utility model can be set at different positions in the dishwasher 100. For example, one of the consumables delivery module 20 and the salt chamber module 30 is set at different positions such as the top, bottom, side, back or door 50 of the dishwasher 100. The positions of the consumables delivery module 20 and the salt chamber module 30 can be adjusted according to actual needs. In addition, the utility model provides some specific placement positions of the consumables delivery module 20 and the salt chamber module 30. Of course, this is not a limitation on the protection scope of the utility model. In some embodiments of the utility model, the consumables delivery module 20 is set outside the inner tank 10, and at least partially above the inner tank 10.

[0096] The consumables delivery module 20 and the salt chamber module 30 can be arranged side by side above the inner tank 10. Thus, the salt chamber module 30 and the consumables delivery module 20 can be arranged together, which is convenient for the production and maintenance of the dishwasher 100, and at the same time, further improves the space utilization of the dishwasher 100. In addition, the salt chamber module 30 and the consumables delivery module 20 can also be discharged in other ways.

[0097] In some embodiments, the waterway assembly 40 includes an integrated waterway component 402 and a cavity portion 401, the cavity portion 401 and the integrated waterway component 402 are connected, the integrated waterway component 402 is arranged on the side wall of the inner tank 10, and the cavity portion 401 is connected to the integrated waterway component 402 and is located below the inner tank. The integrated waterway component 402 can be used to allow fluid to flow into the consumables delivery module 20 and the salt chamber module 30, and the resin chamber 42 can be used to soften the fluid, thereby optimizing the effect of the dishwasher 100 in cleaning dishes and optimizing the performance of the dishwasher 100.

[0098] In addition, in combination with the foregoing, a salt chamber interface 451, an overflow interface 461, a first interface 433 and a second interface 436 are provided at the upper end of the water circuit assembly 40 in the utility model. The salt chamber interface 451, the overflow interface 461, the first interface 433 and the second interface 436 can be arranged at the upper end of the integrated water circuit assembly 402, and a consumable delivery module and a salt chamber module are provided above the inner tank 10, wherein a first connecting tube extending in the up-down direction is provided between the first interface 433 and the consumable delivery module, and a second connecting tube extending in the up-down direction is provided between the second interface 436 and the consumable delivery module; a third connecting tube extending in the up-down direction is provided between the overflow interface 461 and the salt chamber module; a fourth connecting tube extending in the up-down direction is provided between the salt chamber interface 451 and the salt chamber module, and the first connecting tube, the second connecting tube, the third connecting tube and the fourth connecting tube can be arranged side by side.

[0099] In some embodiments, at least a portion of the cavity 401 is disposed below the inner container. By disposing the cavity 401 below the inner container, the space occupied by the cavity 401 can be reduced, the space below the inner container can be fully utilized, and the space utilization rate can be improved. In addition, the lower placement of the cavity 401 can lower the center of gravity of the dishwasher 100 to a certain extent, which is conducive to improving the stability of the dishwasher 100.

[0100] like Fig.12 The dishwasher 100 may further include a door body 50, which is connected to the inner tank and can open and close the washing chamber 101. When the door body 50 is opened, the washing chamber 101 can be opened to facilitate the placement of dishes to be washed or stored in the washing chamber 101; when the door body 50 is closed, the washing chamber 101 can be closed to facilitate the washing of dishes in the washing chamber 101, wherein the consumable material delivery module 20 is arranged on the upper part of the washing machine, and can cover the consumable material delivery module 20 when the door body 50 is closed, and reveal the consumable material delivery module 20 when the door body 50 is opened.
