Technical Field

[0004] The present application relates to the technical field of dishwashers, and in particular to a water diversion valve, a dishwasher dispenser, and a dishwasher. Background Art

[0005] In the related technology, the water diverter valve structure is to directly drive the water diverter valve paddle to rotate by the motor. Since the motor is directly below the water diverter valve paddle, the water pump cannot be placed directly below the water diverter valve. The water pump can only be placed next to the water diverter valve. This will increase the distance from the water pump to the water diverter valve and increase the water flow loss. At the same time, the water coming out of the water pump needs to be diverted 90 degrees before it can flow out of the water diverter valve paddle, which increases the water flow loss for the second time.

[0045] This application provides a water diverter valve 100, a dishwasher dispenser, and a dishwasher, each of which is described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment below have their own specific focus. For details not provided in one embodiment, please refer to the relevant descriptions of other embodiments.

[0046] The following describes an embodiment of the present application in detail. As shown in FIG1 , a water diverter valve 100 according to an embodiment of the present application includes a valve body 110, a valve core 120, and a driver 130. The valve body 110 is used to accommodate the valve core 120. The valve body 110 has an inlet 111 and multiple outlets 112 for controlling the flow of liquid. The valve core 120 is disposed within the valve body 110 and enables the multiple outlets 112 to switchably connect to the inlet 111, thereby controlling the on-off or flow rate of the fluid at the multiple outlets 112. Among them, the number of outlets 112 can be more than two, for example, the number of outlets 112 is two, three, four or five, etc. Taking three outlets as an example, the three outlets on the valve body 110 can be connected to the lower spray arm, upper spray arm and top spray arm of the dishwasher respectively, and water enters the water diverter valve 100 through the inlet 111 of the water diverter valve 100, and the valve core 120 controls the three outlets to switchably connect to the inlet 111. When the valve core 120 controls one outlet 112 to connect to the inlet 111, the lower spray arm or the upper spray arm or the top spray arm of the dishwasher will spray water accordingly. When the valve core 120 controls two outlets 112 to connect to the inlet 111, the lower spray arm and the upper spray arm or the upper spray arm and the top spray arm or the lower spray arm and the top spray arm can be controlled to spray water accordingly. When the valve core 120 controls the three outlets to connect to the inlet 111, the lower spray arm, the upper spray arm and the top spray arm can be controlled to spray water together accordingly. The driving member 130 is in transmission connection with the valve core 120. The movement of the driving member 130 controls the movement of the valve core 120. The driving member 130 is staggered from the inlet 111 in the axial direction of the inlet 111, that is, the driving member 130 is not coaxial with the inlet 111 of the valve body 110, and the driving member 130 is not directly connected to the inlet 111 of the valve body 110. The driving member 130 includes but is not limited to an electric, pneumatic, or hydraulic driving device that converts electricity, air, or hydraulic pressure into force or torque to enable the valve core 120 to move freely or in a controlled manner.

[0047] According to the water diverter valve 100 in the embodiment of the present application, by setting multiple outlets 112 to switchably connect to the valve body 110 inlet 111, a variety of water outlet combinations can be achieved to meet more cleaning methods and improve user experience; by setting a driving member 130 to transmit and connect the valve core 120, the valve core 120 can be rotated to control the flow and on-off of the fluid; by setting the driving member 130 and the inlet 111 to be staggered in the axial direction of the inlet 111, so that the driving member 130 is not directly placed in the axial corresponding position of the inlet 111, it is avoided that the driving member 130 affects the connection between the inlet 111 and the water pump 200, and a position directly below the water diverter valve 100 is reserved for the installation of the water pump 200.

[0048] Alternatively, referring to Figure 1 , in the projection along the axis of inlet 111, driver 130 and inlet 111 are arranged side by side and offset. The central axis of inlet 111 is parallel to the central axis of driver 130, but the projections of driver 130 and inlet 111 in the direction of the central axis do not overlap, meaning the position of driver 130 is offset from that of inlet 111. This arrangement offers the advantage of efficient space utilization and greater ease of installation and operation.

[0049] Alternatively, referring to FIG. 1 , the valve body 110 has a first side and a second side that are opposed to each other. Referring to FIG. 1 , the first side of the valve body 110 is the lower side of the valve body 110 as shown, and the second side of the valve body 110 is the upper side of the valve body 110 as shown. An inlet 111 is provided on the first side of the valve body 110, and an actuator 130 is mounted on the first side of the valve body 110. Locating the inlet 111 on the first side of the valve body 110 facilitates fluid input from that side. Mounting the actuator 130 on the first side of the valve body 110 allows for direct connection to the valve core 120, allowing operation of the actuator 130 to control the movement of the valve core 120. Furthermore, mounting the inlet 111 and actuator 130 on the same side reduces the number of piping connections, simplifying installation and maintenance.

[0050] In addition, the inlet 111 can be used to connect to the water pump 200. By arranging the inlet 111 and the driver 130 on the same side, the driver 130 and the water pump 200 can be arranged on the same side of the valve body 110, which can facilitate assembly, wiring, and maintenance. The dishwasher has an inner tank and a water cup 300, and the water cup 300 is connected to the bottom of the inner tank. The valve body 110 in this application can be integrated with the water cup 300. In this case, the upper side of the valve body 110 can be the inner tank, and the lower side can be a storage space for the water pump 200, etc. By installing the inlet 111 and the driver 130 on the same side, space utilization can be improved and wiring can be facilitated.

[0051] It should also be noted that the first side of the valve body 110 in this application is the lower side of the valve body 110 in the figure, and the second side of the valve body 110 is the upper side of the valve body 110 in the figure. The driving member 130 and the water pump 200 can be arranged on the lower side of the valve body 110, which can lower the center of gravity of the dishwasher and improve the stability of the dishwasher. Of course, the above description is only some specific embodiments of the present application and does not limit the scope of protection of this application.

[0052] Optionally, referring to FIG1 , a plurality of outlets 112 are provided on the second side of the valve body 110, and a valve core 120 is provided between the inlet 111 and the plurality of outlets 112. By providing a plurality of outlets 112 on the second side of the valve body 110, the fluid can be directed to a plurality of different pipes or systems. At the same time, according to the movement or adjustment of the valve core 120, the distribution or closing of the fluid between different outlets 112 can be controlled. The valve core 120 is located between the inlet 111 and the plurality of outlets 112, and plays a role in controlling and regulating the flow direction, flow rate and on-off of the fluid. By controlling the movement of the valve core 120 through the drive member 130, independent control and cross-control of the plurality of outlets 112 can be achieved, and the flow direction and flow rate can be flexibly adjusted to meet different application requirements.

[0053] Optionally, referring to FIG. 1 , the water diverter valve 100 further includes a first gear 140 , and the valve core 120 includes a second gear 121 . The second gear 121 meshes with the first gear 140 , and the first gear 140 is in transmission connection with the driver 130 . Through the transmission connection between the first gear 140 and the driver 130 , when the driver 130 rotates or operates, the first gear 140 also rotates. The meshing of the first gear 140 and the second gear 121 causes the valve core 120 to generate corresponding movement as the first gear 140 rotates. Through this gear transmission mechanism, the movement of the driver 130 can be converted into the movement of the valve core 120, thereby achieving control of the water diverter valve 100 . Furthermore, the gear transmission mechanism has high transmission efficiency and precision, and can provide stable and reliable operational control.

[0054] Optionally, the axis of the first gear 140 is parallel to the axis of the second gear 121, allowing the first gear 140 and the second gear 121 to move on parallel axes, achieving effective transmission while also providing high transmission efficiency and load capacity. When the axis of the first gear 140 and the axis of the second gear 121 are parallel, the first gear 140 and the second gear 121 can achieve transmission through gear meshing, transmitting the movement of the driving member 130 to the valve core 120, thereby controlling the opening or closing of the water diverter valve 100.

[0055] Optionally, the gear ratio between the first gear 140 and the second gear 121 is less than 1, that is, the first gear 140 has fewer teeth than the second gear 121. When the driving member 130 rotates, the meshing of the first gear 140 and the second gear 121 causes the second gear 121 to rotate less than the first gear 140 before the first gear 140 completes one revolution. As a result, the second gear 121 rotates more slowly than the first gear 140, thereby achieving a reduced speed transmission. This configuration is intended to provide a more stable rotational output by reducing the rotational speed of the driving member 130.

[0056] Alternatively, referring to Figure 1 , the first gear 140 includes a toothed portion 141, a hub 142, and a connecting portion 143. The toothed portion 141 surrounds the hub 142, providing meshing and force transmission. The hub 142 is the central axis of the gear and is connected to the toothed portion 141 via the connecting portion 143, bearing the force and torque transmitted by the gear. The connecting portion 143 connects between the hub 142 and the toothed portion 141, providing fixation and support. A positioning cylinder 113 is provided within the valve body 110. The positioning cylinder 113 surrounds the hub 142 and extends between the hub 142 and the toothed portion 141. The positioning cylinder 113 secures the position of the toothed portion 141 relative to the hub 142, thereby ensuring the accuracy and stability of the gear transmission.

[0057] Optionally, the valve core 120 is rotatably mounted on the valve body 110, and the valve core 120 can rotate within the valve body 110. Referring to FIG1 , the valve core 120 is provided with a connecting hole 122, which is connected to the inlet 111 and selectively connected to multiple outlets 112. Specifically, by rotating the valve core 120, the connection between the connecting hole 122 and the inlet 111 and outlet 112 can be adjusted, thereby controlling the distribution and direction of the fluid. Different positions of the valve core 120 and the opening state of the connecting hole 122 can achieve different flow rate and flow direction control, switching the fluid path and achieving multi-way diversion and confluence.

[0058] Alternatively, referring to Figure 1 , multiple outlets 112 are arranged along a circumference centered on the rotational axis of the valve core 120. By rotating the valve core 120, the communication holes 122 can be aligned with different outlets 112, thereby controlling the flow direction of the fluid. This arrangement offers the advantage of selectively connecting different outlets 112 by rotating the valve core 120, enabling control of multiple fluid paths. It also provides flexibility, allowing for the layout of multiple outlets 112 within a smaller volume.

[0059] Optionally, the plurality of outlets 112 may have different flow areas. The different outlets 112 may have different channel sizes or apertures. The differences in flow areas can be used to control or vary the flow rate of the fluid. Typically, an outlet 112 with a larger flow area will have a higher flow rate, while an outlet 112 with a smaller flow area will have a lower flow rate. The flow rate can be adjusted and controlled as needed.

[0060] Optionally, the communication hole 122 is configured to extend along the circumference of the valve core 120. The size of the communication hole 122 is greater than the minimum spacing between two adjacent outlets 112 along the circumference of the valve core 120, that is, the length or extension distance of the communication hole 122 exceeds the minimum spacing between two adjacent outlets 112. In this manner, the communication hole 122 is ensured to remain connected to at least one outlet 112 during rotation of the valve core 120, thereby maintaining fluid connectivity and stability. By ensuring that the communication hole 122 is larger than the minimum spacing, flow interruption or interruption between the communication hole 122 and adjacent outlets 112 during rotation can be prevented, thereby ensuring continuous fluid flow.

[0061] Optionally, at least two outlets 112 have different diameters. Different outlets 112 have different channel diameters or pore sizes, which can produce different flow rates or flow velocities. Typically, an outlet 112 with a larger diameter will have a larger flow rate or flow rate, while an outlet 112 with a smaller diameter will also have a smaller flow rate or flow rate. Outlets 112 with different diameters can be used to control the flow ratio of the fluid, adjust the flow rate, or achieve appropriate fluid distribution. Such an arrangement can be used to achieve flow distribution or regulation, adjusting the flow rate of different outlets 112 as needed to meet the needs of different modes.

[0062] Optionally, the axes of the multiple outlets 112 are located on a circle centered on the axis of the valve core 120. This arrangement ensures that each outlet 112 is positioned equally or similarly relative to the axis of the valve core 120, thereby achieving more balanced fluid distribution or control. Furthermore, the combination of the rotating valve core 120 allows for a greater selection of outlets 112 and provides more fluid paths.

[0063] Optionally, referring to FIG. 1 , the valve core 120 includes a plate portion 123 rotatably connected to the valve body 110 . A communication hole 122 is defined in the plate portion 123 . When the communication hole 122 is in communication with a portion of the plurality of outlets 112 , the plate portion 123 blocks another portion of the plurality of outlets 112 . Taking the aforementioned three outlets as an example, when the communication hole 122 is partially in communication with two of the outlets, the plate portion 123 blocks the remaining portions of the two outlets and the third outlet, thereby controlling the flow direction and passage of the fluid.

[0064] Optionally, the valve core 120 is configured to be suitable for at least two of the multiple outlets 112 to be connected to the inlet 111 at the same time, that is, the valve core 120 can simultaneously guide the fluid to at least two outlets 112. Such a configuration can be used to simultaneously distribute fluid to multiple spray arms connected to the outlets 112, realizing an application scenario in which multiple spray arms are working at the same time. For example, in combination with the aforementioned embodiment, the valve core 120 can simultaneously guide the fluid to the outlets 112 connected to the lower spray arm, upper spray arm, and top spray arm of the dishwasher, realizing a parallel process in which the lower spray arm, upper spray arm, and top spray arm are operated synchronously in pairs or the lower spray arm, upper spray arm, and top spray arm are operated together.

[0065] Optionally, referring to FIG1 , the valve body 110 includes a valve seat 114 and a valve cover 115 , an inlet 111 being provided on the valve seat 114 ; the valve cover 115 covering the valve seat 114 ; a plurality of outlets 112 being provided on the valve cover 115 ; and a valve core 120 being provided between the valve cover 115 and the valve seat 114 . The inlet 111 is provided on the valve seat 114 to guide the fluid into the interior of the valve body 110 . The valve cover 115 covers the valve seat 114 to form a sealed space; a plurality of outlets 112 are provided on the valve cover 115 to distribute the fluid to different pipes or equipment. The valve core 120 is located between the valve cover 115 and the valve seat 114 . The position of the valve core 120 determines the passage and flow direction of the fluid. Its movement can control the on / off or distribution of the fluid by rotation, thus providing the valve body 110 with flexible fluid control capabilities.

[0066] Optionally, a positioning shaft is provided on the valve cover 115, and a positioning hole 124 is provided on the valve core 120. The positioning shaft passes through the positioning hole 124, and the valve core 120 is rotatable about the positioning shaft. The cooperation between the positioning shaft and the positioning hole 124 ensures that the valve core 120 maintains the correct position and orientation during rotation. The positioning shaft serves to locate and guide the movement of the valve core 120, while the positioning hole 124 provides space for the positioning shaft to cooperate.

[0067] Optionally, referring to FIG1 , a plurality of first engaging portions 116 are provided on the periphery of the valve cover 115, and a plurality of second engaging portions 117 are provided on the outer circumferential surface of the valve seat 114. The plurality of first engaging portions 116 are respectively engaged with the plurality of second engaging portions 117. The corresponding engagement of the first engaging portions 116 and the second engaging portions 117 ensures a secure and sealed connection between the valve cover 115 and the valve seat 114, thereby ensuring the stability and reliability of the valve body 110 during operation and use, and further reducing the risk of fluid leakage.

[0068] Optionally, referring to FIG1 , a screw column 118 is provided on the valve seat 114, and a matching hole 119 is provided on the valve cover 115. The matching hole 119 matches the screw column 118 and is connected by screws. The screw column 118 can serve as a threaded fixing point, and the matching hole 119 on the valve cover 115 can have a corresponding thread, so that the screw column 118 and the matching hole 119 can be connected by screws. The screw connection ensures the tightness and stability between the valve cover 115 and the valve seat 114, and can resist loosening caused by vibration and pressure generated during the operation of the valve body 110.
