Description

Technical Field

[0001] The invention relates to a water diversion valve and a cleaning machine using the water diversion valve. Background Art

[0002] To achieve optimal washing results, tabletop and cabinet dishwashers, with their large wash chamber, are typically designed with three spray arms: top, middle, and bottom. During operation, a wash pump delivers water through pipes to the top, middle, and bottom spray arms. The water sprays out from these arms, rinses the dishes, and then falls back into a water cup at the bottom of the dishwasher. The wash pump then delivers the returned water back to the top, middle, and bottom spray arms, completing a cycle. Because there are numerous pipes leading to each spray arm, if all pipes are open, a larger amount of water is required to maintain the system's circulation.

[0003] To achieve water conservation, current dishwashers are generally designed with water diverter valves. These control the connection or disconnection of pipes leading to the various spray arms, thereby adjusting the spraying state of each spray arm as needed and conserving water. Applications CN201220433127.9, "Water Diverter Valve and Dishwasher Having the Same," CN201220591683.9, "Dishwasher, Water Diverter Valve, and Water Blocking Structure Thereof," and CN201220462476.3, "Dishwasher and Water Diverter Valve Thereof," respectively disclose water diverter valve structures for dishwashers.

[0004] Existing water diverter valves are typically connected to the outside of the dishwasher. The water inlet of the diverter valve is located outside the dishwasher and needs to be connected to the dishwasher via a connecting pipe. This requires joints at both ends of the pipe. Commonly used joints, such as clamps and clamps, pose a high risk of water leakage at the connection. Furthermore, existing diverter valves rely primarily on water pressure to squeeze the movable mechanism within the water flow channel to form a sealing surface. This sealing method cannot achieve absolute sealing, resulting in poor sealing performance, which directly affects the water diversion effect of the diverter valve. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a water diverter valve with improved sealing performance by directly connecting the inner cavity of the water diverter valve with the dishwasher in response to the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a water diversion valve that can absolutely seal the water outlet to improve the sealing performance and water diversion effect in response to the current status of the existing technology.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning machine using the above-mentioned water diversion valve in response to the current status of the existing technology.

[0008] The technical solution adopted by the present invention to solve at least one of the above technical problems is: a water diverter valve, characterized in that it includes:

[0009] The housing has a hollow water diversion chamber, a water inlet on the side of the water diversion chamber for docking with the water outlet of the cleaning machine, a first water outlet and a second water outlet on the top of the water diversion chamber, a partition vertically arranged in the water diversion chamber that can separate it into a first cavity corresponding to the first water outlet and a second cavity corresponding to the second water outlet, the water inlet is arranged corresponding to the second cavity, and an opening is provided at the bottom of the partition that can connect the first cavity with the second cavity;

[0010] A fixing seat is provided below the water diversion chamber, and the fixing seat is provided with a mounting hole corresponding to the arrangement of the second water outlet;

[0011] a movable column, capable of moving up and down through the mounting hole and constrained on the fixed seat, the top of the movable column being provided with a sealing plug capable of closing the second water outlet when the movable column rises to the top of the second cavity and closing the opening when the movable column descends to the bottom of the second cavity; and

[0012] The driving assembly is arranged below the fixing seat and is used for driving the movable column to move up and down.

[0013] Preferably, the fixing base has a first water-conducting cavity corresponding to the first cavity and a second water-conducting cavity corresponding to the second cavity, and the opening is formed on the fixing base and located between the first and second water-conducting cavities. This structure facilitates communication between the first and second cavities, allowing water to be discharged through the first water outlet when the second water outlet is closed.

[0014] Preferably, a first plug-in portion protrudes from the top wall of the fixing base, corresponding to the second water-conducting cavity, and is insertable into the second cavity. When the movable column is lowered into the second water-conducting cavity, the sealing plug abuts against the upper edge of the first plug-in portion, isolating the second cavity from the fluid in the second water-conducting cavity. This structure facilitates assembly of the fixing base with the housing and facilitates sealing the opening and the first water outlet by isolating the second cavity from the second water-conducting cavity, allowing water to be discharged through the second cavity and the second water outlet. The sealing plug abuts against the upper end surface of the first plug-in portion to achieve a seal, resulting in a simple, reliable, and low-cost production.

[0015] Preferably, a first convex ring arranged around the periphery of the first plug-in portion is provided on the top wall of the fixing seat, a first sealing groove is formed between the first convex ring and the first plug-in portion, a first sealing ring is embedded in the bottom of the first sealing groove, and the lower edge of the corresponding second cavity on the shell is inserted into the first sealing groove and abuts against the first sealing ring.

The above structure is conducive to achieving sealing between the fixing seat and the shell, thereby avoiding liquid leakage at the connection between the two.

[0016] The water diverter valve of the present invention also includes a telescopic sleeve, the upper end of which is connected to the bottom edge of the sealing plug, and the lower end of which is constrained to a fixed seat below the opening. The mounting hole is arranged corresponding to the inner cavity of the telescopic sleeve, and the movable column passes through the telescopic sleeve and its upper end is connected to the sealing plug. The installation of the telescopic sleeve encloses the assembly structure between the movable column and the sealing plug within the inner cavity of the telescopic sleeve, thereby preventing the intrusion of water and food residue. At the same time, the telescopic sleeve surrounds the mounting hole, which helps to improve the sealing of the mounting hole and prevent leakage.

[0017] Preferably, the telescopic sleeve is a bellows integrally formed with the sealing plug. A circumferentially arranged slot is formed between the bellows and the sealing plug. Accordingly, a collar is provided at the outer edge of the upper end of the movable column, which fits within the slot.

This elastic member is positioned around the outer periphery of the movable column, with its upper end abutting against the inner edge of the upper end of the telescopic sleeve and its lower end abutting against the fixed seat. After extended use, if the drive assembly experiences slight deviations in the displacement of the movable column due to signal transmission or other issues, the upper structure ensures that the sealing plug maintains a good seal and prevents leakage.

This structure promptly drains the accumulated water and residue in the water-dividing cavity.

[0020] In order to facilitate production and assembly, the shell has a first water guide sleeve extending downward along the edge of the first water outlet and a second water guide sleeve extending downward along the edge of the second water outlet, the first water guide sleeve, the second water guide sleeve and the portion between the two together form the partition plate, the fixing seat is arranged at the lower end of the first water guide sleeve and the second water guide sleeve, and the opening is arranged on the fixing seat.

[0021] Preferably, the shell is integrally formed with the bottom of the washing machine. The shell is integrally formed with the washing machine, i.e. the water outlet and the water distribution cavity of the washing machine are also integrally formed without the need for separate connection, which is beneficial to improve the sealing performance of the water distribution cavity.

[0022] In the present application, the driving assembly includes a driving wheel and a driving member, the driving wheel is rotatably arranged below the fixing seat, the driving wheel is provided with guide columns arranged along the axial direction and perpendicular to the movable column, correspondingly, the lower end of the movable column is provided with a transversely or longitudinally extending guide groove, and the guide columns of the driving wheel are reciprocatingly constrained in the guide groove. The driving member rotates the driving wheel, so that the guide columns pull the movable column up and down through the guide groove to realize the alternating opening and closing of the first water outlet and the second water outlet.

[0023] In the above-mentioned solutions, a control assembly capable of controlling the operation of the driving member is further arranged below the fixing seat, and the control assembly is linked with the driving wheel. This structure facilitates the control of the water distribution state and improves the use stability in a certain determined water distribution state.

[0024] Preferably, the outer peripheral wall of the driving wheel is provided with first and second protrusions arranged along the axial direction, and the first and second protrusions are respectively arranged on the opposite sidewalls of the driving wheel. Correspondingly, a first micro switch capable of being closed under the driving of the first protrusion and a second micro switch capable of being closed under the driving of the second protrusion are arranged below the driving wheel. In the closed state of the first micro switch, the first water outlet is opened and the second water outlet is closed. In the closed state of the second micro switch, the first water outlet is closed and the second water outlet is opened.

[0049] The fixed seat 2 of the embodiment is locked with the shell 1 by screws.

[0050] The water distribution valve structure and the cooperating installation structure with the water cup 5 of the embodiment not only have good sealing performance and strong dismounting performance, but also have low cost and convenient installation and maintenance. The cooperating mode of the movable column 6, the telescopic sleeve 7 and the fixed seat 2 and the structure of the water outlet reduce the problem of water storage and residue in the water distribution cavity 11.

[0051] When the driving member 32 drives the driving wheel 31 to rotate to the position where the guide column 311 is located at the upper edge of the driving wheel 31, the movable column 6 rises to the position where the sealing plug 61 closes the second water outlet 112. The opening 21 is in the open state. Water enters the first cavity 101 through the second cavity 102 and the opening 21 and is then output through the first water outlet 111. At this time, the first micro switch is closed. The driving member 32 stops running and remains in this state. When the driving member 32 is operated again, the driving member 32 drives the driving wheel 31 to rotate to the position where the guide column 311 is located at the lower edge of the driving wheel 31. The movable column 6 descends to the position where the sealing plug 61 abuts against the upper end surface of the first plug-in part. The second water guide cavity 104 is fluidically disconnected from the second cavity 102. Water enters the second cavity and is then directly output through the second water outlet 112. At this time, the second micro switch is closed. The driving member 32 stops running and remains in this state.
