Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a water channel structure and a dishwasher. Background Technology

[0002] Traditional dishwashers typically consist of a water tank and a water cup. External liquids are transported to these structures via pipes. However, existing dishwashers suffer from the following drawback: liquids within the water tank cannot be directly transferred to the water cup for water intake into the dishwasher's inner tank, resulting in poor efficiency and flexibility in the water system's water supply to the inner tank. Therefore, further improvements are needed to address this shortcoming in dishwashers. Utility Model Content

[0003] Therefore, it is necessary to provide a water system structure and a dishwasher to address the problem that the liquid in the water tank structure cannot be directly transported to the water cup structure to achieve water intake of the dishwasher inner tub, resulting in poor efficiency and flexibility of the water system for water intake of the dishwasher inner tub.

[0004] A waterway structure includes: a first respirator; a first water tank assembly, the first water tank assembly being able to communicate with the first respirator to form a first waterway; a first water cup assembly, the first water cup assembly being able to communicate with the first respirator to form a second waterway, and the first water cup assembly being able to communicate with the first water tank assembly to form a third waterway; and a first valve body assembly, the first valve body assembly being connected to the first respirator, the first water tank assembly, and the first water cup assembly respectively, the first valve body assembly being located at the intersection of the first waterway, the second waterway, and the third waterway, and the first valve body assembly being used to control the opening or closing of the first waterway, the second waterway, and the third waterway.

[0005] The first aspect of this application discloses a water circuit structure in which a third water circuit is formed by connecting a first water cup assembly and a first water tank assembly. This allows liquid in the first water tank assembly to be directly transported to the first water cup assembly, achieving flexible liquid flow and improving the efficiency of water intake to the inner tank assembly, thus enhancing the product's working efficiency. A first valve assembly can control the opening or closing of the first, second, and third water circuits, enabling the system to select different liquid delivery paths according to actual needs. It can separately control water intake to the first water tank assembly and the inner tank assembly, offering good flexibility. The first valve assembly is located at the intersection of the first, second, and third water circuits, allowing one valve to control all three circuits. This design is more rational, simplifies the water circuit system structure, and improves control accuracy and reliability. The first breather can regulate the air pressure balance in the water circuit system, ensuring smooth liquid flow.

[0006] In one embodiment, the first valve assembly has at least a first state and a second state. When the first valve assembly is in the first state, the first water passage and the second water passage are connected while the third water passage is cut off. When the first valve assembly is in the second state, the second water passage and the third water passage are connected. By connecting the first and second water passages and cutting off the third water passage when the first valve assembly is in the first state, an external water source can supply water to the first water tank assembly, thereby replenishing the stored liquid in the first water tank assembly. By connecting the second and third water passages when the first valve assembly is in the second state, the liquid in the first water tank assembly can be used to supply water to the water cup assembly. This design allows the liquid in the first water tank assembly to be directly transported to the first water cup assembly via the third water passage in specific usage scenarios, reducing dependence on an external water source.

[0007] In one embodiment, the first valve body assembly has a third state, in which the first water passage and the third water passage are connected while the second water passage is cut off. By having the first water passage and the third water passage connected while the second water passage is cut off when the first valve body assembly is in the third state, an external water source can directly supply water to the first water cup assembly, directly achieving water intake into the dishwasher's inner tub. This results in more efficient water intake and is suitable for applications where the dishwasher's inner tub requires a large amount of water. Furthermore, the first valve body assembly also has a first state and a second state, allowing it to select different operating states for different application scenarios, thus improving its practicality.

[0008] In one embodiment, the first valve body assembly is a three-way solenoid valve. A three-way solenoid valve is a type of valve that controls the flow of liquid using electromagnetic force. It has the advantages of rapid response, precise control, and compact structure. It can control the opening or closing of the first, second, and third water channels, ensuring that the liquid flows along a set path, thereby achieving different application scenarios and meeting the liquid supply needs of the water system.

[0009] In one embodiment, a first one-way valve is also included, and the first breather, the first one-way valve, and the first valve body assembly are sequentially connected via a pipeline. By sequentially connecting the first breather, the first one-way valve, and the first valve body assembly via a pipeline, backflow of liquid towards the first breather can be prevented, further enhancing the stability and reliability of the water system.

[0010] In one embodiment, a second check valve is also included, and the first valve body assembly, the second check valve, and the first water tank assembly are sequentially connected via a pipeline. This sequential connection of the first valve body assembly, the second check valve, and the first water tank assembly via a pipeline ensures stable and reliable liquid flow in a predetermined direction, preventing backflow of liquid due to pressure changes or system malfunctions that could affect the fluid delivery function of the water system.

[0011] In one embodiment, a third check valve is also included, and the first valve body assembly, the third check valve, and the first water cup assembly are sequentially connected via a pipe. This sequential connection of the first valve body assembly, the third check valve, and the first water cup assembly via a pipe ensures that liquid backflow does not occur, thus preventing instability in the water system caused by liquid backflow.

[0012] In one embodiment, the first breather is connected to the first valve body assembly via a first pipe, the first valve body assembly is connected to the first water tank assembly via a second pipe, and the first valve body assembly is connected to the first water cup assembly via a third pipe. Connecting the first breather and the first valve body assembly via the first pipe ensures that water from the first breather can be quickly and smoothly transferred to the first valve body assembly, providing basic support for the normal operation of the water system. Connecting the first valve body assembly and the first water tank assembly via the second pipe enables efficient liquid transport between the two assemblies, ensuring that the first water tank assembly can be replenished or released in a timely manner. Furthermore, only one second pipe is needed for both inlet and outlet functions, reducing consumables. Connecting the first valve body assembly and the first water cup assembly via the third pipe also enables efficient liquid transport between them, ensuring that the first water cup assembly can obtain the necessary washing liquid from an external water source or the first water tank assembly in a timely manner.

[0013] In one embodiment, a flow meter is also included, which is disposed on the first respirator and located inside the first respirator. The flow meter is used to detect the liquid flow rate in the first respirator. The flow meter enables real-time detection of the liquid flow rate within the first respirator, providing accurate flow data and allowing for real-time monitoring of liquid flow to prevent over- or under-supply of liquid, thereby improving the efficiency of liquid management.

[0014] In one embodiment, an inner liner assembly is further included, which is disposed on the first water cup assembly and communicates with the first water tank assembly to form a fourth water passage. By connecting the inner liner assembly to the first water tank assembly to form the fourth water passage, gas and liquid within the first water tank assembly can be transported to the inner liner assembly through the fourth water passage, preventing the first water tank assembly from bursting.

[0015] A dishwasher includes the aforementioned water channel structure.

[0016] The second aspect of this application discloses a dishwasher that can control the opening or closing of the first water path, the second water path and the third water path through the setting of the first valve body assembly. It has three selectable water supply modes: water supply from an external liquid source to the first water tank assembly, water supply from an external liquid source to the first water cup assembly, and water supply from the first water tank assembly to the first water cup assembly. This allows the water system to select different liquid delivery paths according to actual needs, providing good flexibility.

[0018] The third aspect of this application discloses a water circuit structure. By incorporating a water softener, hard water ions such as calcium and magnesium are removed from the water, preventing scale formation and thus improving washing performance and protecting the internal components of the dishwasher. A fifth water circuit is formed by sequentially connecting a second breather, a water softener, and a second water tank assembly. This allows external water to be softened by the water softener before being supplied to the second water tank assembly, ensuring stable water quality and supply within the tank. A sixth water circuit is formed by sequentially connecting a second breather, a water softener, and a second water cup assembly. This allows external water to be softened by the water softener before being directly supplied to the second water cup assembly, meeting the need for softened water during the washing process. A second valve assembly allows control of the opening or closing of the fifth, sixth, and seventh water circuits, enabling the system to select different liquid delivery paths according to actual needs, providing high flexibility.

[0019] A dishwasher includes the aforementioned water channel structure.

[0020] The fourth aspect of this application discloses a dishwasher that effectively removes hard water ions through a water softener, thereby softening the liquid. By freely switching between the fourth, fifth, and sixth states of the second valve assembly, the liquid delivery path can be flexibly selected, ensuring the liquid reaches the designated component, thus offering good flexibility.

[0022] The fifth aspect of this application discloses a water circuit structure in which the opening and closing of the eighth and ninth water circuits can be controlled by the third valve assembly, allowing the system to selectively deliver liquid to the third water tank assembly or the third water cup assembly. The opening and closing of the tenth water circuit can be controlled by the fourth valve assembly, thereby controlling the liquid supply from the third water tank assembly to the third water cup assembly. This design allows the system to freely select different delivery modes to meet various liquid supply needs.

[0023] In one embodiment, the third breather is connected to the third valve body assembly via a fourth pipe, and the third valve body assembly is connected to the third water tank assembly via a fifth pipe. The third water tank assembly, the fourth valve body assembly, and the third water cup assembly are sequentially connected via pipes. The arrangement of the fourth and fifth pipes and the connecting pipes between the third water tank assembly, the fourth valve body assembly, and the third water cup assembly ensures smooth liquid flow. The sequential connection of the third water tank assembly, the fourth valve body assembly, and the third water cup assembly via pipes allows the fourth valve body assembly to better control the opening or closing of the tenth water path, improving the efficiency of liquid transport management.

[0041] The first aspect of this application discloses a water circuit structure in which a third water circuit is formed by connecting a first water cup assembly 13 and a first water tank assembly 12. This allows liquid in the first water tank assembly 12 to be directly transported to the first water cup assembly 13, enabling flexible liquid flow, improving the efficiency of water intake to the inner tank assembly, and enhancing product efficiency. A first valve assembly 14 controls the opening or closing of the first, second, and third water circuits, allowing the system to select different liquid delivery paths according to actual needs.
