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 on the upper portion of the partition that can connect the first cavity with the second cavity;

[0010] a baffle rotatably disposed on the partition and always maintaining a tendency to cover the opening;

[0011] a sealing member disposed in the second cavity so as to be movable up and down, wherein when the sealing member rises to the top of the second cavity, the second water outlet is sealed and the baffle is flipped up to open the opening; and when the sealing member descends to the bottom of the second cavity, the second water outlet is opened and the baffle seals the opening, thereby isolating the fluids of the first cavity from the second cavity; and

[0012] The driving assembly is used to drive the sealing member to move up and down.

[0013] In the above solution, the baffle is located in the second cavity and its upper end is rotatably connected above the opening.

[0014] Preferably, a torsion spring is provided at the connection between the baffle and the partition so as to keep the baffle in a downward flipping trend.

[0015] Preferably, the side portion of the sealing member extends outward to form a lever arm which can flip the baffle upwards as the sealing member rises and can be separated from the baffle as the sealing member descends.

[0016] As an improvement, the baffle is provided with a paddle extending toward the second cavity, and the paddle has a first part extending vertically from the edge of the baffle and a second part extending outward from the edge of the first part. The first part is a triangular structure with a small upper end and a large lower end. The second part and the first part together form a concave cavity that can cooperate with the paddle arm guide during the process of the baffle flipping upward, and the lower end of the concave cavity is arranged corresponding to the upper end of the paddle arm.

[0017] With such a structure, as the seal initially moves upward and rotates, the lever arm on the seal gradually inserts into the concave cavity. When the seal is about to seal the second water outlet, the lever arm gives the baffle an upward flipping force to flip the baffle open until the opening is fully opened. At this time, the second water outlet is sealed and the flow channel is switched. The above structure is conducive to improving the accuracy of water distribution.

[0018] Preferably, the upper end of the lever arm is formed into an inverted V-shaped guide portion, and a V-shaped groove is formed on the upper end surface of the lever arm near the inner edge of the guide portion. The upper end of the second portion is partially missing to form a notch. When the baffle is fully opened, the guide portion is arranged through the notch, and the second portion is supported in the V-shaped groove. This structure facilitates the complete support of the baffle above the lever arm when the opening is fully opened, thereby preventing the baffle from disturbing the water flow.

[0019] Preferably, a sealing ring is provided on the upper end surface of the sealing member so as to abut against the top wall of the water diversion cavity outside the second water outlet when the second water outlet is sealed. This structure is conducive to improving the sealing performance of the second water outlet when it is closed.

[0020] In the present invention, the drive assembly includes a screw, a screw sleeve, and a drive member. The screw is rotatably mounted at the bottom of the housing and located within the second cavity. The screw sleeve rotatably engages the screw and has its upper end connected to a sealing member. The drive member is located below the housing, with its output shaft connected to the lower end of the screw. The drive member is a motor. This structure facilitates driving the sealing member up and down to switch the water flow channel.

[0021] As an improvement, the outer walls of the seal and the screw sleeve are provided with transversely and vertically extending baffles. These baffles, together with the inner wall of the second cavity, enclose a compartment that concentrates the water in the second cavity in the upper region. When the second water outlet is open, the compartment is located in the lower portion of the second cavity. When the second water outlet is closed, the compartment is located in the upper portion of the second cavity and communicates with the opening. This structure helps shorten the travel of water in the water diverter valve and reduce water flow capacity loss.

[0022] The water diversion valve of the present invention also includes a control component that can control whether the driving member is in operation, and the control component is linked to the screw rod and the screw rod sleeve. This structure facilitates the control of the water diversion state and improves the stability of use in a certain water diversion state.

[0023] Preferably, a first microswitch is provided at the bottom of the shell, and an extension arm is provided at the lower end of the screw rod, which extends radially and can close the first microswitch when the first water outlet is open and the second water outlet is closed; a second microswitch is provided on the side wall of the shell corresponding to the second water outlet, and the triggering part of the second microswitch passes through the shell and is located in the second cavity, and a protrusion is provided on the outer peripheral wall of the sealing component, which can close the second microswitch when the first water outlet is closed and the second water outlet is open.

[0024] A cleaning machine employing the aforementioned water diversion valve comprises a housing and a water cup located at the bottom of the housing. The bottom wall of the water cup has a recessed bottom cavity. A water pump mechanism corresponding to the bottom cavity is mounted on the bottom of the housing. The water outlet is located on the side of the bottom cavity, and the water diversion valve is located on the outer bottom wall of the water cup. In this cleaning machine, the water outlet of the water cup is directly located on the side of the bottom cavity, thereby directly connecting the water outlet of the water cup with the water inlet of the water diversion valve. This eliminates the need for a separate pipe connecting the water cup to the water diversion cavity as in the prior art. This not only makes assembly more convenient, but also helps improve sealing, prevents water leakage, and enhances the water diversion effect.

[0025] Preferably, the upper portion of the water diversion valve housing is integrally formed with the water cup, with the first and second water outlets located on the bottom wall of the water cup and adjacent to the bottom cavity. The upper portion of the housing is integrally formed with the cleaning machine, meaning the cleaning machine's water outlet and the diversion cavity are also integrally formed, eliminating the need for a separate connection. This improves the sealing of the diversion cavity.

[0026] Compared with the prior art, the advantages of the present invention are that the water diversion chamber of the water diversion valve of the present invention is directly connected to the water outlet of the cleaning machine without the need for connection through a separate pipe. Not only is the assembly method simpler and more convenient, but also the sealing performance of the connection is improved by avoiding the use of water pipe joints. At the same time, the present invention alternately opens and closes the first water outlet and the second water outlet through the cooperation of the seal and the baffle, thereby achieving separate and absolute sealing of the first water outlet and the second water outlet, thereby improving the sealing and reliability in the water diversion state, which is conducive to improving the water diversion effect.

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 7 As described above, the water diversion valve of this embodiment includes a housing 1 , a baffle 2 , a sealing member 5 , a driving assembly 3 and a control assembly 4 .

[0036] like Figure 2 As shown, the housing 1 has a hollow water diversion chamber 11 at the top and a mounting chamber 12 at the bottom. The side of the water diversion chamber 11 has a water inlet 113 for docking with the water outlet 71 of the cleaning machine. The top of the water diversion chamber 11 has a first water outlet 111 and a second water outlet 112. Figure 3 As shown, a partition 6 is vertically arranged in the water diversion chamber 11 to separate it into a first cavity 101 corresponding to the first water outlet 111 and a second cavity 102 corresponding to the second water outlet 112. The water inlet 113 is arranged corresponding to the second cavity 102. An opening 61 is opened in the upper portion of the partition 6 to connect the first cavity 101 with the second cavity 102. The installation compartment 12 is used to install the drive assembly 3 and part of the control assembly 4.

[0037] Baffle 2 is rotatably mounted on partition 6, maintaining a tendency to cover opening 61. In this embodiment, baffle 2 is located within second cavity 102, with its upper end rotatably connected to opening 61 via a rotating shaft. A torsion spring 62 is provided at the connection between baffle 2 and partition 6, ensuring that baffle 2 maintains a downward tilting tendency.

[0038] The seal 5 is disc-shaped and is disposed in the second cavity 102 so as to be movable up and down. When the seal 5 rises to the top of the second cavity 102, it seals the second water outlet 112 and flips up the baffle 3, thereby opening the opening 61. When the seal 5 descends to the bottom of the second cavity 102, the second water outlet 112 opens and the baffle 2 seals the opening 61, thereby isolating the fluids in the first cavity 101 from the second cavity 102. An annular groove 52 is provided on the upper end surface of the seal 5 near the edge, in which a sealing ring 53 is retained. When the second water outlet 112 is sealed, the sealing ring 53 abuts against the top wall of the water diversion cavity 11 outside the second water outlet 112. This structure helps to improve the sealing performance of the second water outlet 112 when it is closed.

[0039] The driving assembly 3 is used to drive the sealing member 5 to move up and down. The control assembly 4 is used to control whether the driving assembly 3 is running or not.

[0040] Specifically, such as Figure 3As shown, the side of the seal 5 extends outward to form a lever arm 51 that can lift the baffle 2 upward as it rises and separate from the baffle 2 as it falls. The baffle 2 is provided with a lever 21 extending toward the second cavity 102, as shown in FIG. Figure 7 As shown, the paddle 21 has a first portion 211 extending vertically from the edge of the baffle 2 and a second portion 212 extending outward from the edge of the first portion 211. The first portion 211 is perpendicular to the baffle 2 and has a triangular structure with a small upper end and a large lower end. The second portion 212 is perpendicular to the first portion 211 and is connected to the outer edge of the first portion 211. The second portion 212 and the first portion 211 together form a concave cavity 213 that can guide and cooperate with the paddle arm 51 during the process of the baffle 2 being flipped upward. The lower end of the concave cavity 213 is arranged corresponding to the upper end of the paddle arm 51.

[0041] As the seal 5 initially moves upward and rotates, the lever arm 51 on the seal 5 gradually inserts into the concave cavity 213. When the seal 5 seals the second water outlet 112, the lever arm 51 exerts an upward flipping force on the baffle 2 to flip the baffle 2 open until the opening 61 is fully opened. At this time, the second water outlet 112 is sealed and the flow channel is switched. The above structure is conducive to improving the accuracy of water distribution.

[0042] The upper end of the lever arm 51 is formed into an inverted V-shaped guide portion 511. A V-shaped groove 512 is formed on the upper end surface of the lever arm 51 near the inner edge of the guide portion 511. The upper end of the second portion 212 is partially missing, forming a notch 214. When the baffle 2 is fully opened, the guide portion 511 is placed through the notch 214, and the second portion 212 is supported in the V-shaped groove 512. This structure facilitates the complete support of the baffle 2 above the lever arm 51 when the opening 61 is fully opened, thereby preventing the baffle 2 from disturbing the water flow.

[0043] In this embodiment, if Figure 3 As shown, the drive assembly 3 includes a screw 31, a screw sleeve 32, and a drive member 33. The screw 31 is rotatably disposed at the bottom of the housing 1 and is located in the second cavity 102. The screw sleeve 32 rotatably cooperates with the screw 31 and is connected to the seal 5 at its upper end. In this embodiment, the screw sleeve 32 and the seal 5 are integrally formed, forming a closed cavity with only a lower end. The inner wall of the cavity is provided with a thread that cooperates with the screw. The drive member 33 is a motor, which is disposed below the housing 1 and has an output shaft 331 connected to the lower end of the screw 31. The above structure facilitates driving the seal 5 up and down to switch the water flow channel.

[0044] In this embodiment, the seal 5 and the outer peripheral wall of the screw sleeve 32 are provided with a baffle 100 extending horizontally and vertically. The baffle 100 forms a semi-enclosed chamber, which is open on the side corresponding to the water inlet 113 and the partition 6, and the other side walls are closed. The baffle 100 and the inner wall of the second cavity 102 together enclose a partition 103 that can concentrate the water in the second cavity 102 in the upper area. When the second water outlet 112 is open, the baffle 103 is located in the lower part of the second cavity 102. When the second water outlet 112 is closed, the baffle 103 is located in the upper part of the second cavity 102 and is connected to the opening 61. This structure is conducive to shortening the stroke of water flow in the water diversion valve and reducing the loss of water flow capacity. The lever arm 51 is located above the baffle 100. When the baffle 2 is fully opened, the baffle 2 is also located above the baffle 100.

[0045] like Figure 4 、 6 As shown, the control assembly 4 is linked with the screw rod 31 and the screw rod sleeve 32 to facilitate the control of the water diversion state and improve the stability of use in a certain water diversion state. Specifically, a first micro switch 41 is provided at the bottom of the housing 1, and an extension arm 311 is provided at the lower end of the screw rod 31, which extends radially and can close the first micro switch 41 when the first water outlet 111 is closed and the second water outlet 112 is open; a second micro switch 42 is provided on the side wall of the housing 1 corresponding to the second water outlet 112, and the trigger portion 421 of the second micro switch 42 passes through the housing 1 and is located in the second cavity 102. A protrusion 54 is provided on the outer peripheral wall of the sealing member 5, which can close the second micro switch 42 when the first water outlet 111 is open and the second water outlet 112 is closed. The above-mentioned first micro switch 41 and second micro switch 42 together constitute the control assembly 4.

[0046] In this embodiment, a cleaning machine using the aforementioned water diversion valve includes a housing and a water cup 7 located at the bottom of the housing. The bottom wall of the water cup 7 has a recessed bottom cavity 72. A water pump mechanism corresponding to the bottom cavity 72 is mounted on the bottom of the housing. A water outlet 71 is provided on the side of the bottom cavity 72, and the water diversion valve is provided on the outer bottom wall of the water cup 7. In this cleaning machine, the water outlet 71 of the water cup 7 is directly provided on the side of the bottom cavity 72, thereby directly connecting the water outlet 71 of the water cup 7 with the water inlet 113 of the water diversion valve. This eliminates the need for a separate pipe connecting the water cup and the water diversion cavity as in the prior art. This not only makes assembly more convenient, but also helps improve sealing, prevents water leakage, and enhances the water diversion effect.

[0047] The upper portion of the water diversion valve housing 1 is integrally formed with the water cup 7. The first and second water outlets 111, 112 are located on the bottom wall of the water cup 7, adjacent to the bottom cavity 72. The upper portion of the housing 1 is integrally formed with the cleaning machine, meaning the cleaning machine's water outlet 113 and the water diversion cavity 11 are also integrally formed, eliminating the need for a separate connection. This improves the sealing performance of the water diversion cavity 11.

[0048] The water diverter valve structure of this embodiment and its coordinated installation with the water cup 5 not only ensures excellent sealing and strong disassembly, but also offers low cost and convenient installation and maintenance. The coordinated structure of the seal 5 and the screw sleeve 32, the barrier 100 and the second cavity 102, and the drain outlet structure reduce the problem of water and debris accumulation in the water diverter cavity 11.

[0049] When using the water diverter valve of this embodiment, the driving member 33 causes the screw rod 31 to rotate and drives the screw rod sleeve 32 and the sealing member 5 to rise until the sealing member 5 seals the second water outlet 112. The baffle 2 is flipped upward by the upward moving arm 51, and the opening 61 on the partition 6 is in the open state. Water enters the first cavity 101 through the second cavity 102 and the opening 61 and is discharged through the first water outlet 111. At this time, the second microswitch 42 is closed, and the driving member 33 stops operating and remains in this state; after the driving member 33 is operated again, the screw rod 31 rotates and drives the screw rod sleeve 32 and the sealing member 5 to descend until the sealing member 5 is located below the opening 61, and the second water outlet 112 is opened. The baffle 2 closes the opening 61 under the action of the torsion spring, and the fluid between the first cavity 101 and the second cavity 102 is isolated. After entering the second cavity 102, the water is directly discharged through the second water outlet 112. At this time, the first microswitch 41 is closed, and the driving member 33 stops operating and remains in this state.
