Description

Technical Field

[0001] This utility model relates to the field of home appliances, and in particular to a dishwasher liquid supply component and a dishwasher. Background Technology

[0002] In modern kitchen appliances, dishwashers, with their efficient and convenient dishwashing capabilities, are gradually becoming a powerful assistant in family life. Currently, dishwashers store some water in a tank, which is then transferred to a water cup during operation. This water cup then provides the necessary cleaning water to the dishwashing area inside the drum, thus completing the dishwashing process. However, current dishwashers lack a simple and controllable water supply between the water tank, water cup, and drum. Utility Model Content

[0003] Therefore, it is necessary to provide a dishwasher liquid supply component and a dishwasher to address the problem of complex water supply processes.

[0004] A dishwasher liquid supply assembly includes: a valve body assembly having a liquid passage chamber, the valve body assembly having a first opening, a second opening, and a third opening communicating with the liquid passage chamber, the first opening being for communicating with an external liquid source; a water tank assembly communicating with the second opening; a water cup assembly communicating with the third opening; and an inner liner abutting against the water tank assembly and capable of heat exchange between the inner liner and the water tank assembly; the valve body assembly having a first connected state and a second connected state, the first opening communicating with the second opening when the valve body assembly is in the first connected state, and the passage between the third opening and the first and second openings being blocked when the valve body assembly is in the second connected state.

[0005] This application discloses a dishwasher liquid supply assembly. The liquid passage chamber, set within the valve body assembly, has a rationally designed internal space to efficiently accommodate and guide liquid flow. A first opening, a second opening, and a third opening communicate with the liquid passage chamber, providing the valve body assembly with strong connectivity flexibility. In the first communication state, the first opening connects to the second opening, allowing for convenient and efficient introduction of liquid from an external source into the water tank assembly. For example, when the liquid level in the dishwasher's water tank is low, this communication state allows for rapid replenishment from an external water source, ensuring timely replenishment of the water tank assembly and maintaining the dishwasher's normal operation. This prevents interruption of operation due to water tank shortage, significantly improving the continuity and reliability of the dishwasher's operation. In the second communication state, the passage between the third opening and the first and second openings is blocked. This design plays a crucial role in ensuring precise liquid supply during different operating stages. It effectively prevents liquid from flowing into the water cup assembly when not needed, avoiding unnecessary liquid waste. The inner liner abuts against the water tank assembly and allows for heat exchange, a design that significantly improves energy efficiency. During dishwasher operation, heat from the inner tub is transferred to the liquid in the water tank assembly, raising its temperature. This heat exchange reduces the energy consumption required for additional liquid heating, lowering operating costs. Traditional dishwashers consume significant amounts of electricity to heat cold water to the appropriate washing temperature, while heat exchange utilizes the residual heat generated during the inner tub's operation to heat the liquid, saving energy.

[0006] In one embodiment, the valve body assembly further has a third connected state, in which the first opening is connected to the third opening, and the passage between the second opening and the first and third openings is blocked. When the valve body assembly is in the third connected state, the first opening is connected to the third opening, and the passage between the second opening and the first and third openings is blocked. This connection method creates a unique liquid delivery path, directly connecting an external liquid source to the water cup assembly through the first opening, making operation more convenient.

[0007] In one embodiment, a one-way valve is also included, which connects an external liquid source to the first opening. The one-way valve reduces the structural complexity of the valve body assembly. During use, the one-way valve controls the reverse flow of water without requiring operation of the valve body assembly. This simplifies the structural design and reduces the complexity of the valve body assembly, making operation easier.

[0008] In one embodiment, the valve body assembly includes a valve shell and a valve core assembly. The valve shell has the liquid passage chamber and has a first opening, a second opening, and a third opening. The valve core assembly is disposed on the valve shell, with a portion of the valve core assembly located within the liquid passage chamber and capable of movement within it. When the valve core assembly moves relative to the liquid passage chamber, it has a first position and a second position. When the valve core assembly is in the first position, the first opening communicates with the second opening, and the third opening blocks the passage between the first and second openings. When the valve core assembly is in the second position, the first opening, the second opening, and the third opening are respectively connected to the liquid passage chamber. By assuming different positions as the valve core assembly moves within the liquid passage chamber, multiple communication states can be achieved. When the valve core assembly is in the first position, the first opening communicates with the second opening, and the third opening is blocked. This communication state allows for efficient delivery of liquid from an external liquid source to the water tank assembly, ensuring that the water tank can be replenished with sufficient cleaning fluid in a timely manner. Precise movement of the valve core assembly within the liquid passage chamber enables precise control of the liquid flow direction. In the first position, the system ensures that liquid flows only between the first and second openings, effectively preventing liquid from flowing into the third opening and making the amount of liquid entering the tank controllable during the water intake phase. When the valve core assembly is in the second position, the first, second, and third openings are connected to the liquid passage chamber, allowing liquid to be supplied to the water cup assembly via the tank assembly. This enables precise control of the liquid flow direction, meeting the needs of complex cleaning scenarios. The valve body, as the main support for the liquid passage chamber and the carrier for the openings of the first, second, and third openings, provides a solid and stable structural foundation for the entire valve body assembly. The valve core assembly is mounted on the valve body and partially located within the liquid passage chamber, ensuring smooth and stable movement of the valve core assembly within the liquid passage chamber.

[0009] In one embodiment, the valve core assembly further includes a third position when moving relative to the liquid passage chamber. When the valve core assembly is in the third position, the first opening communicates with the third opening, and the second opening is blocked from the passage between the first and third openings. When the valve core assembly is in the third position, the first and third openings are connected, and the second opening is blocked. The movement of the valve core assembly allows for the supply of water from an external liquid source to the water cup assembly, resulting in more diverse water supply methods, a simple and reliable control process, and an increase in the water supply options for the water cup assembly.

[0010] In one embodiment, the liquid-passing chamber includes a first channel, a second channel, a third channel, and a buffer chamber. The first channel communicates with the second channel, and the first and second channels are connected to the buffer chamber via a liquid-passing port. The third channel is connected to the buffer chamber. The valve core assembly can open or close the liquid-passing port. The first channel has a first opening, the second channel has a second opening, and the third channel has a third opening. The liquid-passing chamber, composed of the first, second, and third channels and the buffer chamber, and with the first and second channels connected, constructs an efficient and orderly liquid transport network. When the dishwasher is in normal operating condition, such as when adding liquid to the water tank assembly, the liquid enters the first channel through the first opening. Since the first and second channels are connected, the liquid can flow smoothly to the water tank assembly through the second opening in the second channel. The first and second channels are connected to the buffer chamber via liquid-passing ports, and the third channel is also connected to the buffer chamber. The buffer chamber can buffer and distribute the high-speed flowing liquid. The valve core assembly's ability to open or close the liquid-passing port enables precise control of the liquid flow direction. By controlling the position of the valve core assembly, the flow direction of the liquid can be flexibly switched in different operating states of the dishwasher.

[0011] In one embodiment, the valve core assembly includes a driving component and a sealing component. The driving component is disposed on the valve housing, and the sealing component is disposed on the driving component and extends into the buffer chamber. The driving component can drive the sealing component to move. When the driving component drives the sealing component to move, it has at least a first position and a second position. When the sealing component is in the first position, it is spaced apart from the liquid outlet. When the sealing component is in the second position, it abuts against the wall of the liquid outlet and seals the liquid outlet. Through the coordinated design of the driving component and the sealing component, precise control of the liquid outlet is achieved, thereby accurately controlling the liquid flow direction. Under the drive of the driving component, the sealing component can reliably and tightly abut against the wall of the liquid outlet, effectively sealing the liquid outlet. Through the precise control of the sealing component position by the driving component, more cleaning functions and application scenarios are expanded for the dishwasher. When the sealing component is in the first position, it is spaced apart from the liquid outlet, and the liquid passage between the first channel, the second channel, and the buffer chamber remains unobstructed. The cleaning fluid can smoothly enter the second channel from the water tank assembly and flow through the buffer chamber to the third channel. When the sealing assembly is in the second position, it abuts against the wall of the liquid outlet and seals the outlet, allowing for rapid water supply to the water tank assembly.

[0012] In one embodiment, the sealing assembly includes a sealing head and an elastic element. The driving assembly has a movable channel, and a portion of the sealing head is movably disposed within the movable channel. One end of the elastic element abuts against the sealing head, and the other end of the elastic element abuts against the driving assembly. The driving assembly can drive the sealing head to move. When the driving assembly drives the sealing head to move, it has at least a third position and a fourth position. When the sealing head is in the third position, it is spaced apart from the liquid outlet. When the sealing head is in the fourth position, it abuts against the wall of the liquid outlet and blocks the liquid outlet. The elastic element in the sealing assembly greatly enhances the stability and reliability of the sealing head in blocking the liquid outlet. When the sealing head is in the fourth position under the action of the driving assembly, one end of the elastic element abuts against the sealing head, and the other end abuts against the driving assembly. This puts the elastic element in a compressed state, thereby generating a continuous elastic force acting on the sealing head. This elasticity ensures a tighter seal between the sealing head and the wall of the liquid inlet, effectively preventing liquid leakage during dishwasher operation regardless of pressure changes. The elastic element provides excellent cushioning as the drive assembly moves the sealing head from position three to position four, or vice versa. Furthermore, the elastic element allows the sealing head to approach or move away from the liquid inlet more slowly, gradually reducing the liquid flow rate and minimizing the impact caused by changes in liquid flow direction. This protects the internal structure of the equipment and extends its lifespan.

[0013] In one embodiment, the drive component is an electromagnetic component, and at least a portion of the sealing head is a magnetic element. This combination of an electromagnetic drive component and a magnetic sealing head achieves a rapid-response drive effect. When the dishwasher's control system issues a command to change the liquid flow direction, the electromagnetic component is energized to generate a magnetic field, which quickly attracts the magnetic sealing head.

[0014] In one embodiment, the valve body assembly further includes a bracket assembly on which the valve housing is disposed, the bracket assembly being designed for mounting on the dishwasher base. The bracket assembly greatly simplifies the installation of the valve body assembly. The valve housing is mounted on the bracket assembly, which is specifically designed for mounting on the dishwasher housing. This design eliminates the need for complex positioning and securing operations when installing the valve body assembly onto the dishwasher.

[0015] In one embodiment, the valve core assembly includes a motor, a rotating shaft, and a plug. The motor is mounted on the valve housing and is drively connected to the rotating shaft. The plug is mounted on the rotating shaft, and the motor drives the rotating shaft to rotate, thereby moving the plug to open or close the liquid passage. Precise opening and closing control of the liquid passage can be achieved through motor drive. The motor can precisely control the rotation angle of the rotating shaft by accurately adjusting its output power and speed, thus accurately controlling the degree of plugging of the liquid passage. The direct drive connection between the motor and the rotating shaft makes power transmission efficient and stable. Compared to some complex mechanical transmission structures, this reduces energy loss and the probability of mechanical failure.

[0016] The second aspect of this application discloses a dishwasher, including: the dishwasher liquid supply assembly described above.

[0017] The second aspect of this application provides a dishwasher that allows for more flexible control of the internal liquid supply process by using a liquid supply component. When different water supply methods need to be switched, the state of the valve assembly can be controlled. The operation process is simple, and the use of water in the water tank assembly can reduce the energy consumption of the dishwasher, which is beneficial for energy saving.

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The following describes some embodiments of the dishwasher liquid supply assembly and dishwasher according to the present invention with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 1 to 13As shown, this embodiment discloses a dishwasher liquid supply assembly, including: a valve body assembly 1 with a liquid passage chamber 101, the valve body assembly 1 having a first opening 102, a second opening 103 and a third opening 104 communicating with the liquid passage chamber 101, the first opening 102 being used to communicate with an external liquid source; a water tank assembly 2, the water tank assembly 2 communicating with the second opening 103; a water cup assembly 3, the water cup assembly 3 communicating with the third opening 104; an inner liner 4, the inner liner 4 abutting against the water tank assembly 2 and capable of heat exchange between the inner liner 4 and the water tank assembly 2; the valve body assembly 1 having a first connected state and a second connected state, the valve body assembly 1 being in the first connected state with the first opening 102 communicating with the second opening 103, and the valve body assembly 1 being in the second connected state with the third opening 104 blocking the channel between the first opening 102 and the second opening 103.

[0042] This application discloses a dishwasher liquid supply assembly. A liquid passage chamber 101, located within a valve body assembly 1, has a rationally designed internal space to efficiently accommodate and guide liquid flow. A first opening 102, a second opening 103, and a third opening 104 communicate with the liquid passage chamber 101. This multi-opening design provides the valve body assembly 1 with strong communication flexibility. In the first communication state, the first opening 102 and the second opening 103 are connected. This communication method allows for convenient and efficient introduction of liquid from an external liquid source into the water tank assembly 2. For example, when the liquid level in the dishwasher's water tank is insufficient, this communication state allows for rapid replenishment from an external water source, ensuring timely replenishment of the water tank assembly 2 and maintaining the dishwasher's normal operation. This prevents interruption of operation due to insufficient water in the tank, significantly improving the continuity and reliability of the dishwasher's operation. In the second communication state, the passage between the third opening 104 and the first and second openings 102 and 103 is blocked. This design plays a crucial role in ensuring accurate liquid supply during different operating stages of the liquid supply system. It effectively prevents liquid from flowing into the water cup assembly 3 when not needed, avoiding unnecessary liquid waste. The inner tank 4 abuts against the water tank assembly 2 and can exchange heat, a design that significantly improves energy efficiency. During dishwasher operation, heat from the inner tank 4 can be transferred to the liquid in the water tank assembly 2, raising the liquid's temperature. This heat exchange reduces the energy consumption required for additional liquid heating, lowering operating costs. Traditional dishwashers consume a significant amount of electricity to heat cold water to the appropriate washing temperature; however, through heat exchange, the waste heat generated by the inner tank 4 during operation can be used to heat the liquid, saving energy.

[0043] like Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the valve body assembly 1 also has a third connected state. When the valve body assembly 1 is in the third connected state, the first opening 102 is connected to the third opening 104, and the passage between the second opening 103 and the first opening 102 and the third opening 104 is blocked. When the valve body assembly 1 is in the third connected state, the first opening 102 is connected to the third opening 104, and the passage between the second opening 103 and the first opening 102 and the third opening 104 is blocked. This connection method opens up a unique liquid delivery path, directly connecting the external liquid source to the water cup assembly 3 through the first opening 102, making operation more convenient.

[0044] like Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further includes a one-way valve 5, which is used to connect an external liquid source and the first opening 102. The one-way valve 5 reduces the structural complexity of the valve body assembly 1. During use, the one-way valve 5 controls the reverse flow of water without requiring operation of the valve body assembly 1. This reduces the complexity of the valve body assembly 1 during structural design and facilitates operation.

[0045] like Figures 1 to 3As shown, in addition to the features of the above embodiments, this embodiment further defines: the valve body assembly 1 includes a valve shell 11 and a valve core assembly 12. The valve shell 11 is provided with a liquid passage chamber 101, and the valve shell 11 has a first opening 102, a second opening 103, and a third opening 104. The valve core assembly 12 is disposed on the valve shell 11, and a portion of the valve core assembly 12 is located within the liquid passage chamber 101 and can move within the liquid passage chamber 101. When the valve core assembly 12 moves relative to the liquid passage chamber 101, it has a first position and a second position: when the valve core assembly 12 is in the first position, the first opening 102 communicates with the second opening 103, and the passage between the third opening 104 and the first opening 102 and the second opening 103 is blocked; when the valve core assembly 12 is in the second position, the first opening 102, the second opening 103, and the third opening 104 are respectively connected to the liquid passage chamber 101. By the valve core assembly 12 moving within the liquid passage chamber 101, it can present different positions, thereby realizing multiple communication states. When the valve core assembly 12 is in the first position, the first opening 102 is connected to the second opening 103, while the third opening 104 is blocked. This connection allows for efficient delivery of liquid from an external source to the water tank assembly 2, ensuring that the water tank can be replenished with sufficient cleaning fluid in a timely manner. The precise movement of the valve core assembly 12 within the liquid passage chamber 101 allows for precise control of the liquid flow direction. In the first position, liquid flows only between the first opening 102 and the second opening 103, effectively preventing liquid from flowing into the third opening 104, thus making the amount of liquid entering the water tank controllable during the water intake phase. When the valve core assembly 12 is in the second position, the first opening 102, the second opening 103, and the third opening 104 are connected to the liquid passage chamber 101, allowing the water tank assembly 2 to supply liquid to the water cup assembly 3, achieving fine control of the liquid flow direction and meeting the needs of complex cleaning scenarios. The valve housing 11 serves as the main support for the liquid passage chamber 101 and the opening carrier for the first opening 102, the second opening 103, and the third opening 104, providing a solid and stable structural foundation for the entire valve body assembly 1. The valve core assembly 12 is mounted on the valve housing 11 and partially located within the liquid passage chamber 101, ensuring the smoothness and stability of the valve core assembly 12's movement within the liquid passage chamber 101.

[0046] In addition to the features of the above embodiments, this embodiment further specifies that: when the valve core assembly 12 moves relative to the liquid passage chamber 101, it also includes a third position. When the valve core assembly 12 is in the third position, the first opening 102 and the third opening 104 are connected, and the second opening 103 is blocked from the channel between the first opening 102 and the third opening 104. When the valve core assembly 12 is in the third position, the first opening 102 and the third opening 104 are connected, and the second opening 103 is blocked. The movement of the valve core assembly 12 can realize the supply of water from an external liquid source to the water cup assembly 3, making the water supply method more diverse, the control process simple and reliable, and increasing the water supply methods for the water cup assembly 3.

[0047] like Figure 4 , Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: the liquid passage chamber 101 includes a first channel 1011, a second channel 1012, a third channel 1013, and a buffer chamber 1014. The first channel 1011 is connected to the second channel 1012, and the first channel 1011, the second channel 1012, and the buffer chamber 1014 are connected through a liquid passage port 1015. The third channel 1013 is connected to the buffer chamber 1014. The valve core assembly 12 can open or close the liquid passage port 1015. The first channel 1011 has a first opening 102, the second channel 1012 has a second opening 103, and the third channel 1013 has a third opening 104. The liquid passage chamber 101 is formed by the first channel 1011, the second channel 1012, the third channel 1013, and the buffer chamber 1014, and the first channel 1011 is connected to the second channel 1012, thus constructing an efficient and orderly liquid transfer network. When the dishwasher is in normal operating condition, such as when adding liquid to the water tank assembly 2, the liquid enters the first channel 1011 through the first opening 102. Since the first channel 1011 is connected to the second channel 1012, the liquid can flow smoothly through the second opening 103 on the second channel 1012 to the water tank assembly 2. The first channel 1011 and the second channel 1012 are connected to the buffer chamber 1014 through the liquid outlet 1015, and the third channel 1013 is also connected to the buffer chamber 1014. The buffer chamber 1014 can buffer and distribute the high-speed flowing liquid. The valve core assembly 12 can open or close the liquid outlet 1015, a design that achieves precise control of the liquid flow direction. In different operating states of the dishwasher, the liquid flow direction can be flexibly switched by controlling the position of the valve core assembly 12.

[0048] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines that: the valve core assembly 12 includes a driving assembly 121 and a blocking assembly 122. The driving assembly 121 is disposed on the valve housing 11, and the blocking assembly 122 is disposed on the driving assembly 121 and extends into the buffer cavity 1014. The driving assembly 121 can drive the blocking assembly 122 to move. When the driving assembly 121 drives the blocking assembly 122 to move, it has at least a first position and a second position. When the blocking assembly 122 is in the first position, the blocking assembly 122 is spaced apart from the liquid outlet 1015. When the blocking assembly 122 is in the second position, the blocking assembly 122 abuts against the hole wall of the liquid outlet 1015 and the blocking assembly 122 blocks the liquid outlet 1015. Through the coordinated design of the drive component 121 and the sealing component 122, precise control of the liquid outlet 1015 is achieved, thereby accurately controlling the liquid flow direction. Driven by the drive component 121, the sealing component 122 can reliably and tightly abut against the wall of the liquid outlet 1015, effectively sealing the liquid outlet 1015. The precise control of the sealing component 122's position by the drive component 121 expands the dishwasher's cleaning functions and application scenarios. When the sealing component 122 is in the first position, it is spaced apart from the liquid outlet 1015, keeping the liquid passages between the first channel 1011, the second channel 1012, and the buffer chamber 1014 unobstructed. The cleaning fluid can smoothly enter the second channel 1012 from the water tank assembly, flow through the buffer chamber 1014, and then to the third channel 1013. When the sealing component 122 is in the second position, it abuts against the wall of the liquid outlet 1015 and seals it, allowing for rapid water supply to the water tank assembly 2.

[0049] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the sealing component 122 includes a sealing head 1221 and an elastic member 1222, the driving component 121 is provided with a movable channel, a portion of the sealing head 1221 is movably disposed in the movable channel, one end of the elastic member 1222 abuts against the sealing head 1221, and the other end of the elastic member 1222 abuts against the driving component 121, the driving component 121 can drive the sealing head 1221 to move, and the driving component 121 drives the sealing head 1221 to move, having at least a third position and a fourth position. When the sealing head 1221 is in the third position, the sealing head 1221 is spaced apart from the liquid outlet 1015. When the sealing head 1221 is in the fourth position, the sealing head 1221 abuts against the hole wall of the liquid outlet 1015 and the sealing head 1221 blocks the liquid outlet 1015. The elastic element 1222 in the sealing assembly 122 greatly enhances the stability and reliability of the sealing head 1221 in sealing the liquid outlet 1015. When the sealing head 1221 is in the fourth position under the action of the drive assembly 121, one end of the elastic element 1222 abuts against the sealing head 1221, and the other end abuts against the drive assembly 121. This puts the elastic element 1222 in a compressed state, thereby generating a continuous elastic force acting on the sealing head 1221. This elastic force causes the sealing head 1221 to abut more tightly against the wall of the liquid outlet 1015, ensuring that liquid leakage from the liquid outlet 1015 can be effectively prevented during dishwasher operation, regardless of changes in liquid pressure. During the process of the drive assembly 121 driving the sealing head 1221 to move from the third position to the fourth position, or from the fourth position to the third position, the elastic element 1222 plays a good buffering role. Moreover, the presence of the elastic element 1222 allows the sealing head 1221 to approach or move away from the liquid outlet 1015 relatively slowly, gradually reducing the liquid flow rate and thus reducing the impact caused by the switching of liquid flow direction, protecting the internal structure of the equipment, and extending the service life of the equipment.

[0050] In addition to the features of the above embodiments, this embodiment further specifies that: the drive component 121 is an electromagnetic component, and at least a portion of the sealing head 1221 is a magnetic element. The combination of an electromagnetic drive component 121 and a magnetic element in at least a portion of the sealing head 1221 achieves a rapid-response drive effect. When the dishwasher's control system issues a command to change the liquid flow direction, the electromagnetic component is energized to generate a magnetic field, which can quickly attract the magnetic sealing head 1221.

[0051] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the valve body assembly 1 also includes a bracket assembly 13, the valve housing 12 is disposed on the bracket assembly 13, and the bracket assembly 13 is used for mounting on the dishwasher base. The bracket assembly 13 greatly facilitates the installation of the valve body assembly 1. The valve housing 11 is disposed on the bracket assembly 13, and the bracket assembly 13 is specifically designed for mounting on the dishwasher cabinet. This design eliminates the need for complex positioning and fixing operations when installing the valve body assembly 1 onto the dishwasher.

[0052] In addition to the features of the above embodiments, this embodiment further specifies that: the valve core assembly 12 includes a motor, a rotating shaft, and a plug. The motor is mounted on the valve housing 11 and is driven by the rotating shaft. The plug is mounted on the rotating shaft, and the motor can drive the rotating shaft to rotate, thereby driving the plug to move and open or close the liquid passage 1015. Precise opening and closing control of the liquid passage 1015 can be achieved through motor drive. The motor can precisely control the rotation angle of the rotating shaft by precisely adjusting its output power and speed, thereby accurately controlling the degree of sealing of the liquid passage 1015 by the plug. The direct drive connection between the motor and the rotating shaft makes power transmission efficient and stable. Compared with some complex mechanical transmission structures, this reduces energy loss and the probability of mechanical failure.

[0053] In this embodiment, the water inlet method is as follows: First, an external water source enters the water tank. The valve assembly 1 connects the first opening 102 and the second opening 103, and blocks the channel between the third opening 104 and the first opening 102 and the second opening 103. The external water source flows into the water tank with a rated amount of liquid. Then, the liquid in the water tank enters the inner tank. The valve assembly connects the first opening 102 and the second opening 103, and the second opening 102 and the third opening 103. The liquid in the water tank flows into the inner tank cavity. After the water inlet is completed, the valve assembly 1 blocks the channel between the third opening 104 and the first opening 102 and the second opening 103 to prevent the liquid in the inner tank from flowing back.

[0054] Example 2

[0055] A dishwasher includes: the aforementioned dishwasher liquid supply assembly.

[0056] The second aspect of this application provides a dishwasher that allows for more flexible control of the internal liquid supply process by using a liquid supply component. When different water supply methods need to be switched, the state of the valve body component 1 can be controlled. The operation process is simple, and the use of water in the water tank component 2 can reduce the energy consumption of the dishwasher, which is beneficial for energy saving.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
