Description

Technical Field

[0001] The present invention relates to the field of household appliances, and particularly to a dishwasher. Background Art

[0002] In the current field of household appliances, dishwashers have gradually become a standard in many family kitchens, bringing people a convenient and efficient tableware cleaning experience. However, in actual use, a relatively significant problem has emerged with dishwashers, that is, the long water inlet time. The heating process is relatively long, consuming a large amount of energy and time. From the perspective of long-term use, this not only increases the electricity cost of the family, but also goes against the current concept of energy conservation and environmental protection. In the context of increasingly tight energy and growing emphasis on energy conservation and emission reduction by people, the problem of long water inlet time and high energy consumption of dishwashers needs to be solved urgently to improve the overall performance and market competitiveness of dishwasher products. Summary of the Invention

[0003] Based on this, it is necessary to provide a dishwasher aiming at the problems of long heating process and high energy consumption.

[0004] A dishwasher includes: a cabinet assembly, the cabinet assembly is provided with an installation cavity; an inner container assembly, the inner container assembly is arranged on the cabinet assembly and located in the installation cavity, and an installation space is formed between the inner container assembly and the inner wall of the cabinet assembly; a water tank assembly, the water tank assembly is arranged on the inner container assembly and located at the installation space, the water tank assembly abuts against the inner container assembly, the water tank assembly is provided with a receiving cavity, and the water tank assembly is provided with a liquid outlet communicated with the receiving cavity; a breather, the breather is arranged on the inner container assembly and located at the installation space; a water cup, the water cup is arranged on the inner container assembly; a valve body assembly, the valve body assembly is respectively communicated with the liquid outlet of the water tank assembly, the breather and the water cup; the valve body assembly has at least a first state and a second state. When the valve body assembly is in the first state, the cabinet assembly is communicated with the breather. When the valve body assembly is in the second state, the water tank assembly is communicated with the water cup.

[0005] The present application discloses a dishwasher. The installation cavity provided in the cabinet assembly builds a stable infrastructure for the entire dishwasher, provides a safe protection space for internal components, and prevents external factors from damaging internal precision components. At the same time, the installation cavity enables precise installation of other components such as the inner tank assembly, ensuring the relative position accuracy between components. The installation space formed after the inner tank assembly is installed in the installation cavity of the cabinet assembly cleverly reserves installation positions for components such as the water tank assembly and the breather, realizing efficient utilization of space and avoiding layout conflicts of components in a limited space. The water tank assembly is arranged on the inner tank assembly and is located at the installation space and abuts against it, enabling better heat exchange with the inner tank assembly. Its accommodating cavity is specifically used for storing water or liquid, providing a continuous liquid source for the cleaning work of the dishwasher. The liquid outlet is communicated with the accommodating cavity, capable of precisely controlling the output volume and output direction of the liquid. When the dishwasher is working, the water tank assembly can timely and stably deliver an appropriate amount of water to the cleaning area according to a preset program, ensuring the coherence and efficiency of the cleaning process. Moreover, since the water tank assembly is closely connected to the inner tank assembly, the energy loss and leakage risk during the liquid transportation process are reduced, and the reliability of the water supply and liquid supply system of the entire dishwasher is improved. The breather is installed on the inner tank assembly and is located at the installation space, playing a key role in balancing air pressure during the operation of the dishwasher. During the cleaning process of the dishwasher, especially during the drainage and water inlet stages, the internal air pressure changes violently. The breather can timely adjust the air pressure inside the inner tank assembly to ensure that the air pressure is always within a suitable range. The valve body assembly is communicated with the cabinet assembly, the breather, and the water cup, and has at least two working states, greatly enriching the functions of the dishwasher. In the first state, the water tank assembly 3 is communicated with the breather. In this state, external water can be transported into the water tank assembly after passing through the breather. When the valve body assembly is in the second state, the water tank assembly is communicated with the water cup. At this time, the water in the water tank assembly enters the water cup through the valve body assembly for use, realizing simplification of control.

[0006] In one embodiment, the horizontal height of the water tank assembly is higher than the horizontal height of the water cup, and the horizontal height of the breather is higher than the horizontal height of the water cup. By having the horizontal height of the water tank assembly higher than that of the water cup, a natural power advantage is provided. When the dishwasher is working, based on the principle of gravity, the water or liquid in the water tank assembly can flow smoothly through the liquid outlet to the water cup without the need for an additional power pump, simplifying the internal structure of the dishwasher and reducing the energy consumption and failure risk brought by the power pump. At the same time, since the water tank is at a higher position, it can effectively prevent water from flowing back into the water tank, preventing water pollution and ensuring the cleanliness of the water for the next use, thereby ensuring the consistency of the cleaning effect. The fact that the horizontal height of the breather is higher than that of the water cup can make the water in the water tank assembly more easily enter the water cup.

[0007] In one embodiment, it further includes a water softener, which is respectively communicated with the respirator and the water cup. The water softener is respectively communicated with the respirator and the water cup, reducing the generation of water scale in the inner tank and related components, ensuring the cleanliness of the internal environment of the dishwasher and the stability of air pressure regulation. Softening the liquid flowing into the water cup reduces the difficulty of equipment maintenance and extends the service life of the equipment.

[0008] In one embodiment, the first part of the water tank assembly is located between the top wall of the inner tank assembly and the top wall of the cabinet assembly, the second part of the water tank assembly is located between the side wall of the inner tank assembly and the side wall of the cabinet assembly, and the liquid outlet of the water tank assembly is located on the second part of the cabinet assembly. With the first part of the water tank assembly between the top wall of the inner tank assembly and the top wall of the cabinet assembly, and the second part located between the side wall of the inner tank assembly and the side wall of the cabinet assembly, this layout makes the overall dishwasher more compact and can increase the capacity of the water tank assembly. The water tank assembly reasonably distributed on the top and side walls enhances the structural stability of the entire dishwasher. The water tank part on the top increases the weight distribution on the top, making the machine more stable when placed and less likely to shake or tip over. The water tank part on the side wall fits closely with the inner tank assembly and the cabinet assembly, like a reinforced frame, further enhancing the structural strength of the whole machine, reducing the possibility of damage to the machine caused by external collision or vibration during daily use, and extending the service life of the dishwasher.

[0009] In one of the embodiments, the water tank assembly includes a water tank body, an overflow pipe, a liquid passing member, and a locking member. The water tank body is provided with the accommodation cavity, and the water tank body is provided with the liquid outlet. The overflow pipe is disposed on the water tank body and located within the accommodation cavity. The overflow pipe extends along the height direction of the water tank body. A part of the locking member passes through the liquid passing member and then is connected to the overflow pipe. The inner tank assembly is clamped between the water tank body and the liquid passing member. The inner tank assembly is provided with an overflow hole, and the overflow hole is disposed opposite to the overflow pipe. The liquid passing member is provided with an overflow port, and the accommodation cavity, the overflow pipe, the overflow hole, and the overflow port are communicated in sequence. The water tank body is used to store water, providing sufficient liquid reserve for the cleaning work of the dishwasher. The overflow pipe is disposed on the water tank body and located within the accommodation cavity, and extends along the height direction of the water tank body. This design can effectively prevent the liquid in the water tank body from damaging the internal structure due to overfilling or abnormal pressure during operation. When the liquid level exceeds the height of the overflow pipe, the excess liquid can be drained through the overflow pipe, providing a reliable guarantee for the safe and stable operation of the dishwasher. The overflow port provided on the liquid passing member cooperates with the overflow pipe and the overflow hole to form a smooth overflow path. When an overflow occurs, the liquid can be drained through the accommodation cavity, the overflow pipe, the overflow hole, and the overflow port in sequence, ensuring the efficiency and stability of the overflow process. In addition, the inner tank assembly is clamped between the water tank body and the liquid passing member, and the liquid passing member plays a role in strengthening the connection and fixing. It not only makes the connection between the water tank assembly and the inner tank assembly closer, but also can disperse the vibration and pressure generated during the operation of the dishwasher, enhancing the stability of the entire structure, and further ensuring the reliability of the connection between the components during the long-term use of the dishwasher. A part of the locking member passes through the liquid passing member and then is connected to the overflow pipe, and this connection method greatly enhances the connection strength between the overflow pipe and the liquid passing member.

[0010] In one embodiment, the valve body assembly includes a valve housing and a valve core assembly. The valve housing is provided with a liquid passage chamber. The valve housing is provided with a first opening, a second opening, and a third opening that communicate with the liquid passage chamber. The first opening communicates with the breather, the second opening communicates with the water tank assembly, and the third opening communicates with the water cup. The valve core assembly is disposed on the valve housing, and a part of the valve core assembly is located in the liquid passage chamber and can move within the liquid passage chamber. 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 opening and the second opening; when the valve core assembly is in the second position, the first opening, the second opening, and the third opening respectively communicate with the liquid passage chamber. By providing a liquid passage chamber in the valve housing, a key passage for the internal circulation of the dishwasher is provided. The provided first opening, second opening, and third opening respectively communicate with the breather, the water tank assembly, and the water cup, enabling the flow between different components. When the valve core assembly is in the first position, the first opening communicates with the second opening, while the third opening blocks the passage between the first two. At this time, the water in the breather can enter the water tank assembly through the second opening. When the valve core assembly is in the second position, the first opening, the second opening, and the third opening respectively communicate with the liquid passage chamber. After the water enters the liquid passage chamber from the water tank assembly through the second opening, it can flow to the water cup, and the water flowing through the first opening to the breather will be blocked by the breather. The valve core assembly can move within the liquid passage chamber to achieve the switching of different positions, providing a flexible control method for the dishwasher.

[0011] In one embodiment, the liquid passage cavity includes a first channel, a second channel, a third channel, and a buffer cavity. The first channel communicates with the second channel. The first channel and the second channel communicate with the buffer cavity through liquid passing ports. The third channel communicates with the buffer cavity. The valve core assembly can open or close the liquid passing ports. The first channel is provided with the first opening, the second channel is provided with the second opening, and the third channel is provided with the third opening. The complex structure composed of the first channel, the second channel, the third channel, and the buffer cavity provides a highly refined control mechanism for the flow of liquid and gas inside the dishwasher. It makes the material exchange between different components more orderly and efficient, greatly improving the overall performance of the dishwasher. The first channel communicates with the second channel, and the first opening and the second opening are respectively provided, which are respectively connected to the breather and the water tank assembly. When the dishwasher is working, when the valve core assembly is in a specific position, the water in the breather can flow into the first channel through the first opening, then enter the second channel through the connection, and flow to the water tank assembly through the second opening. It can control the delivery path and flow rate of the water. Since the first channel and the second channel communicate with the buffer cavity through the liquid passing ports, the buffer cavity can balance the pressure in the two channels to a certain extent. The third channel is provided with the third opening connected to the water cup and communicates with the buffer cavity, and the water in the water tank assembly can enter the water cup for use.

[0012] In one embodiment, the valve core assembly includes a driving component and a blocking component. The driving component is arranged on the valve housing, and the blocking component is arranged on the driving component and extends into the buffer cavity. The driving component can drive the blocking component to move. When the driving component drives the blocking component to move, it at least has a first position and a second position. When the blocking component is in the first position, the blocking component is spaced from the liquid passing port. When the blocking component is in the second position, the blocking component abuts against the pore wall of the liquid passing port and the blocking component blocks the liquid passing port. The driving component provides power support for the operation of the entire valve core assembly. It can accurately drive the blocking component to move, enabling the blocking component to switch between different positions, and can accurately control the opening and closing states of the liquid passing port according to the preset program. The blocking component is arranged on the driving component and extends into the buffer cavity. When it is in the second position, it can closely abut against the pore wall of the liquid passing port to effectively block the liquid passing port. Its good sealing performance ensures that when the liquid passing port needs to be blocked, there will be no liquid leakage, guaranteeing the precise control of the liquid flow direction inside the dishwasher. The close cooperation between the driving component and the blocking component greatly optimizes the working process of the dishwasher.

[0013] In one embodiment, the plugging assembly includes a plugging head and an elastic member. The driving assembly is provided with an active channel. A part of the plugging head is movably arranged in the active channel. One end of the elastic member abuts against the plugging head, and the other end of the elastic member abuts against the driving assembly. The driving assembly can drive the plugging head to move. When the driving assembly drives the plugging head to move, it has at least a third position and a fourth position. When the plugging head is in the third position, the plugging head is spaced from the liquid passing port. When the plugging head is in the fourth position, the plugging head abuts against the pore wall of the liquid passing port and the plugging head plugs the liquid passing port. By movably arranging a part of the plugging head in the active channel of the driving assembly, it is allowed to move precisely between the third position and the fourth position under the action of the driving assembly. When in the third position, the plugging head is spaced from the liquid passing port, and the liquid passing port is opened to ensure that water can flow smoothly between the channels. When the plugging head is in the fourth position, it closely abuts against the pore wall of the liquid passing port to effectively plug the liquid passing port. One end of the elastic member abuts against the plugging head, and the other end abuts against the driving assembly, providing a buffering and automatic reset function for the work of the plugging assembly. The elastic member can automatically adjust the plugging force of the plugging head on the liquid passing port according to the pressure change.

[0014] In one embodiment, a part of the inner container assembly protrudes, and a part of the box body assembly is recessed. The protruding part of the inner container assembly is adapted to the recessed part of the box body assembly. By matching the protrusion of the inner container assembly with the groove of the box body assembly, the assembly of the box body assembly can be made more stable. At the same time, the cooperation of the protrusion and the groove can increase the contact area between the two, ensuring heat transfer between the inner container assembly and the box body assembly.

[0015] In one embodiment, the water tank assembly is provided with a notch. By providing the notch in the water tank assembly, components can be assembled at the notch. Description of the Drawings

[0042] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0043] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0044] The following describes some embodiments of the dishwasher of the present invention with reference to the drawings.

[0045] As Figures 1 to 18 shown, this embodiment discloses a dishwasher, including: a cabinet assembly 1, the cabinet assembly 1 is provided with an installation cavity 101; an inner tank assembly 2, the inner tank assembly 2 is arranged on the cabinet assembly 1 and located in the installation cavity 101, and an installation space is formed between the inner tank assembly 2 and the inner wall of the cabinet assembly 1; a water tank assembly 3, the water tank assembly 3 is arranged on the inner tank assembly 2 and located at the installation space, the water tank assembly 3 is in contact with the inner tank assembly 2, the water tank assembly 3 is provided with a receiving cavity 301, and the water tank assembly 3 is provided with a liquid outlet 302 communicating with the receiving cavity 301; a breather 4, the breather 4 is arranged on the inner tank assembly 2 and located at the installation space; a water cup 5, the water cup 5 is arranged on the inner tank assembly 2; a valve body assembly 6, the valve body assembly 6 is respectively communicated with the liquid outlet 302 of the water tank assembly 3, the breather 4 and the water cup 5; the valve body assembly 6 has at least a first state and a second state. When the valve body assembly 6 is in the first state, the water tank assembly 3 is communicated with the breather 4, and when the valve body assembly 6 is in the second state, the water tank assembly 3 is communicated with the water cup 5.

[0046] The present application discloses a dishwasher. The installation cavity 101 provided in the cabinet assembly 1 builds a stable infrastructure for the entire dishwasher, provides a safe protection space for internal components, and prevents external factors from damaging internal precision components. At the same time, the installation cavity 101 enables precise installation of other components such as the inner liner assembly 2, ensuring the relative position accuracy between components. After the inner liner assembly 2 is installed in the installation cavity 101 of the cabinet assembly 1, the formed installation space cleverly reserves installation positions for components such as the water tank assembly 3 and the breather 4, realizing efficient utilization of space and avoiding layout conflicts of components in a limited space. The water tank assembly 3 is arranged on the inner liner assembly 2 and is located at the installation space and abuts against it, enabling better heat exchange with the inner liner assembly 2. Its accommodation cavity 301 is specifically used for storing water or liquid, providing a continuous liquid source for the cleaning work of the dishwasher. The liquid outlet 302 is communicated with the accommodation cavity 301, capable of precisely controlling the output volume and output direction of the liquid. When the dishwasher is working, the water tank assembly 3 can timely and stably convey an appropriate amount of water to the cleaning area according to a preset program, ensuring the coherence and efficiency of the cleaning process. Moreover, since the water tank assembly 3 is closely connected to the inner liner assembly 2, the energy loss and leakage risk during the liquid transportation process are reduced, improving the reliability of the water supply and liquid supply system of the entire dishwasher. The breather 4 is installed on the inner liner assembly 2 and is located at the installation space, playing a key role in balancing air pressure during the operation of the dishwasher. During the cleaning process of the dishwasher, especially during the drainage and water inlet stages, the internal air pressure will change violently. The breather 4 can timely adjust the air pressure inside the inner liner assembly 2 to ensure that the air pressure is always within an appropriate range. The valve body assembly 6 is communicated with the cabinet assembly 1, the breather 4, and the water cup 5, and has at least two working states, greatly enriching the functions of the dishwasher. In the first state, the water tank assembly 3 is communicated with the breather 4. In this state, external water can be conveyed into the water tank assembly 3 after passing through the breather 4. When the valve body assembly 6 is in the second state, the water tank assembly 3 is communicated with the water cup 5. At this time, the water in the water tank assembly 3 enters the water cup 5 through the valve body assembly 6 for use, realizing simplification of control.

[0047] In addition to the features of the above embodiments, this embodiment further defines that: the horizontal height of the water tank assembly 3 is higher than the horizontal height of the water cup 5, and the horizontal height of the respirator 4 is higher than the horizontal height of the water cup 5. By setting the horizontal height of the water tank assembly 3 higher than that of the water cup 5, a natural power advantage is provided. When the dishwasher is working, based on the principle of gravity, the water or liquid in the water tank assembly 3 can flow smoothly through the liquid outlet 302 to the water cup 5 without the need for an additional power pump, simplifying the internal structure of the dishwasher and reducing the energy consumption and failure risk brought by the power pump. At the same time, due to the relatively high position of the water tank, the backflow of water into the water tank can be effectively avoided, preventing water pollution and ensuring the cleanliness of the water for the next use, thereby ensuring the consistency of the cleaning effect. The fact that the horizontal height of the respirator 4 is higher than that of the water cup 5 can make the water in the water tank assembly 3 more easily enter the water cup 5.

[0048] As Figure 3 and Figure 4 shown, in addition to the features of the above embodiments, this embodiment further defines that: it further includes a water softener 7, and the water softener 7 is respectively connected to the respirator 4 and the water cup 5. The water softener 7 is respectively connected to the respirator 4 and the water cup 5, reducing the generation of water scale in the inner tank and related components, ensuring the cleanliness of the internal environment of the dishwasher and the stability of air pressure regulation. Softening the liquid flowing into the water cup 5 reduces the difficulty of equipment maintenance and extends the service life of the equipment.

[0049] As Figure 3 and Figure 4 shown, in addition to the features of the above embodiments, this embodiment further defines that: the first part of the water tank assembly 3 is located between the top wall of the inner tank assembly 2 and the top wall of the cabinet assembly 1, the second part of the water tank assembly 3 is located between the side wall of the inner tank assembly 2 and the side wall of the cabinet assembly 1, and the liquid outlet 302 of the water tank assembly 3 is located on the second part of the cabinet assembly 1. By having the first part of the water tank assembly 3 between the top wall of the inner tank assembly 2 and the top wall of the cabinet assembly 1 and the second part between the side wall of the inner tank assembly 2 and the side wall of the cabinet assembly 1, this layout makes the overall dishwasher more compact and can increase the capacity of the water tank assembly 3. The water tank assembly 3 reasonably distributed on the top and side walls enhances the structural stability of the entire dishwasher. The water tank part at the top increases the weight distribution at the top, making the machine more stable when placed and less likely to shake or tip over. The water tank part on the side wall fits tightly with the inner tank assembly 2 and the cabinet assembly 1, acting like a reinforced frame, further enhancing the structural strength of the whole machine and reducing the possibility of damage to the machine caused by external collisions or vibrations during daily use, thus extending the service life of the dishwasher.

[0050] As Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines that: the water tank assembly 3 includes a water tank body 31, an overflow pipe 32, a liquid passing member 33, and a locking member 34. The water tank body 31 is provided with a receiving cavity 301, and the water tank body 31 is provided with a liquid outlet 302. The overflow pipe 32 is arranged on the water tank body 31 and is located in the receiving cavity 301. The overflow pipe 32 extends along the height direction of the water tank body 31. A part of the locking member 34 passes through the liquid passing member 33 and then is connected to the overflow pipe 32. The inner tank assembly 2 is clamped between the water tank body 1 and the liquid passing member 33. The inner tank assembly 2 is provided with an overflow hole 201, and the overflow hole 201 is arranged opposite to the overflow pipe 21. The liquid passing member 33 is provided with an overflow port 303. The receiving cavity 301, the overflow pipe 32, the overflow hole 201, and the overflow port 303 are communicated in sequence. The water tank body 31 is used to store water, providing sufficient liquid reserve for the cleaning work of the dishwasher. The overflow pipe 32 is arranged on the water tank body 31 and is located in the receiving cavity 301, and extends along the height direction of the water tank body 31. This design can effectively prevent the liquid in the water tank body 31 from damaging the internal structure due to overfilling or abnormal pressure during operation. When the liquid level exceeds the height of the overflow pipe 32, the excess liquid can be drained through the overflow pipe 32, providing a reliable guarantee for the safe and stable operation of the dishwasher. The overflow port 303 provided on the liquid passing member 33 cooperates with the overflow pipe 32 and the overflow hole 201 to form a smooth overflow path. When an overflow occurs, the liquid can be drained through the receiving cavity 301, the overflow pipe 32, the overflow hole 201, and the overflow port 303 in sequence, ensuring the efficiency and stability of the overflow process. In addition, the inner tank assembly 2 is clamped between the water tank body 31 and the liquid passing member 33, and the liquid passing member 33 plays a role in strengthening the connection and fixation. It not only makes the connection between the water tank assembly 3 and the inner tank assembly 2 more compact, but also can disperse the vibration and pressure generated during the operation of the dishwasher, enhancing the stability of the entire structure, and further ensuring the reliability of the connection between the components during the long-term use of the dishwasher. A part of the locking member 34 passes through the liquid passing member 33 and then is connected to the overflow pipe 32, and this connection method greatly enhances the connection strength between the overflow pipe 32 and the liquid passing member 33.

[0051] As Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further defines that the valve body assembly 6 includes a valve housing 61 and a valve core assembly 62. The valve housing 61 is provided with a liquid passage chamber 601. The valve housing 61 is provided with a first opening 602, a second opening 603, and a third opening 604 that communicate with the liquid passage chamber 601. The first opening 602 communicates with the breather 4, the second opening 603 communicates with the water tank assembly 3, and the third opening 604 communicates with the water cup 5. The valve core assembly 62 is disposed on the valve housing 61, and a part of the valve core assembly 62 is located in the liquid passage chamber 601 and can move within the liquid passage chamber 601. When the valve core assembly 62 moves relative to the liquid passage chamber 601, it has a first position and a second position: when the valve core assembly 62 is in the first position, the first opening 602 communicates with the second opening 603, and the third opening 604 blocks the passage between the first opening 602 and the second opening 603; when the valve core assembly 62 is in the second position, the first opening 602, the second opening 603, and the third opening 604 respectively communicate with the liquid passage chamber 601. By providing the liquid passage chamber 601 in the valve housing 61, a key passage for the circulation inside the dishwasher is provided. The provided first opening 602, second opening 603, and third opening 604 respectively communicate with the breather 4, the water tank assembly 3, and the water cup 5, enabling the flow between different components. When the valve core assembly 62 is in the first position, the first opening 602 communicates with the second opening 603, while the third opening 604 blocks the passage between the former two. At this time, the water in the breather 4 can enter the water tank assembly 3 through the second opening 603. When the valve core assembly 62 is in the second position, the first opening 602, the second opening 603, and the third opening 604 respectively communicate with the liquid passage chamber 601. After the water enters the liquid passage chamber 601 from the water tank assembly 3 through the second opening 603, it can flow to the water cup 5, and the water flowing to the breather 4 through the first opening 602 will be blocked by the breather 4. The valve core assembly 62 can move within the liquid passage chamber 601 to achieve the switching of different positions, providing a flexible control method for the dishwasher.

[0052] As Figure 15 , Figure 16 , Figure 17 and Figure 18As shown, in addition to the features of the above embodiments, this embodiment further defines that the liquid passage chamber 601 includes a first channel 6011, a second channel 6012, a third channel 6013, and a buffer chamber 6014. The first channel 6011 communicates with the second channel 6012. The first channel 6011 and the second channel 6012 communicate with the buffer chamber 6014 through a liquid passage port 6015. The third channel 6013 communicates with the buffer chamber 6014. The valve core assembly 62 can open or close the liquid passage port 6015. The first channel 6011 is provided with a first opening 602, the second channel 6012 is provided with a second opening 603, and the third channel 6013 is provided with a third opening 604. Through the complex structure composed of the first channel 6011, the second channel 6012, the third channel 6013, and the buffer chamber 6014, a highly refined control mechanism is provided for the flow of liquid and gas inside the dishwasher. It makes the material exchange between different components more orderly and efficient, greatly improving the overall performance of the dishwasher. The first channel 6011 communicates with the second channel 6012, and is respectively provided with the first opening 602 and the second opening 603, which are respectively connected to the breather 4 and the water tank assembly 3. When the dishwasher is working, when the valve core assembly 62 is in a specific position, the water in the breather 4 can flow into the first channel 6011 through the first opening 602, then enter the second channel 6012 through the connection, and flow to the water tank assembly 3 through the second opening 603. It can control the delivery path and flow rate of the water. Since the first channel 6011 and the second channel 6012 communicate with the buffer chamber 6014 through the liquid passage port 6015, the buffer chamber 6014 can balance the pressure in the two channels to a certain extent. The third channel 6013 is provided with a third opening 604 connected to the water cup 5 and communicates with the buffer chamber 6014, and the water in the water tank assembly 3 can enter the water cup 5 for use.

[0053] As Figure 15 and Figure 16As shown, in addition to the features of the above embodiments, this embodiment further defines that: the valve core assembly 62 includes a driving assembly 621 and a plugging assembly 622. The driving assembly 621 is arranged on the valve housing 61, and the plugging assembly 622 is arranged on the driving assembly 621 and extends into the buffer chamber 6014. The driving assembly 621 can drive the plugging assembly 622 to move. When the driving assembly 621 drives the plugging assembly 622 to move, it has at least a first position and a second position. When the plugging assembly 622 is in the first position, the plugging assembly 622 is spaced from the liquid passing port 6015. When the plugging assembly 622 is in the second position, the plugging assembly 622 abuts against the pore wall of the liquid passing port 6015 and the plugging assembly 622 plugs the liquid passing port 6015. The driving assembly 621 provides power support for the operation of the entire valve core assembly 62. It can accurately drive the plugging assembly 622 to move, enabling the plugging assembly 622 to switch between different positions, and can accurately control the opening and closing states of the liquid passing port 6015 according to a preset program. The plugging assembly 622 is arranged on the driving assembly 621 and extends into the buffer chamber 6014. When it is in the second position, it can tightly abut against the pore wall of the liquid passing port 6015 to effectively plug the liquid passing port 6015. Its good sealing performance ensures that there will be no liquid leakage when the liquid passing port 6015 needs to be plugged, guaranteeing the precise control of the liquid flow direction inside the dishwasher. The close cooperation between the driving assembly 621 and the plugging assembly 622 greatly optimizes the working process of the dishwasher.

[0054] As Figure 15 and Figure 16As shown, in addition to the features of the above embodiments, this embodiment further defines that the plugging assembly 622 includes a plugging head 6221 and an elastic member 6222. The driving assembly 621 is provided with a movable channel. A part of the plugging head 6221 is movably arranged in the movable channel. One end of the elastic member 6222 abuts against the plugging head 6221, and the other end of the elastic member 6222 abuts against the driving assembly 621. The driving assembly 621 can drive the plugging head 6221 to move. When the driving assembly 621 drives the plugging head 6221 to move, it has at least a third position and a fourth position. When the plugging head 6221 is in the third position, the plugging head 6221 is spaced from the liquid passing port 6015. When the plugging head 6221 is in the fourth position, the plugging head 6221 abuts against the pore wall of the liquid passing port 6015 and the plugging head 6221 plugs the liquid passing port 6015. By movably arranging a part of the plugging head 6221 in the movable channel of the driving assembly 621, it is allowed to move precisely between the third position and the fourth position under the action of the driving assembly 621. When in the third position, the plugging head 6221 is spaced from the liquid passing port 6015, and the liquid passing port 6015 is opened to ensure that water can flow smoothly between the channels. When the plugging head 6221 is in the fourth position, it closely abuts against the pore wall of the liquid passing port 6015 to effectively plug the liquid passing port 6015. One end of the elastic member 6222 abuts against the plugging head 6221, and the other end abuts against the driving assembly 621, providing a buffering and automatic reset function for the operation of the plugging assembly 622. The elastic member 6222 can automatically adjust the plugging force of the plugging head 6221 on the liquid passing port 6015 according to the pressure change.
