[0041] This application provides a water distribution valve 100, a dispenser of a dishwasher and a dishwasher, which will be described in detail below. It should be noted that the description order of the following embodiments does not serve as a limitation on the preferred order of the embodiments of this application. And in the following embodiments, each embodiment is described with its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0042] The following details the embodiments of the present invention, such as Figure 1As shown, the water distribution valve 100 according to an embodiment of the present invention includes a valve body 110, a valve core 120, and a driving member 130. The valve body 110 is used to accommodate the valve core 120. The valve body 110 has an inlet 111 and a plurality of outlets 112 for controlling the flow of liquid. The valve core 120 is disposed within the valve body 110 and enables the plurality of outlets 112 to be selectively connected to the inlet 111 to control the on / off or flow rate of the fluid at the plurality of outlets 112. Among them, the number of the outlets 112 can be more than two. For example, the number of the outlets 112 is two, three, four, five, etc. Taking three outlets as an example, the three outlets on the valve body 110 can be respectively connected to the lower spray arm, the upper spray arm, and the top spray arm of the dishwasher. Water enters the water distribution valve 100 through the inlet 111 of the water distribution valve 100. The valve core 120 controls the three outlets to be selectively connected to the inlet 111. When the valve core 120 controls one outlet 112 to be connected to the inlet 111, the lower spray arm or the upper spray arm or the top spray arm of the dishwasher sprays water and operates accordingly. When the valve core 120 controls two outlets 112 to be connected 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 correspondingly controlled to spray water and operate. When the valve core 120 controls the three outlets to be connected to the inlet 111, the lower spray arm, the upper spray arm, and the top spray arm can be correspondingly controlled to spray water and operate together. The driving member 130 is in transmission connection with the valve core 120, and the movement of the valve core 120 is controlled by the movement of the driving member 130. Moreover, the driving member 130 is offset 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. Among them, the driving member 130 includes, but is not limited to, an electric, pneumatic, or hydraulic driving device, which converts electric power, pneumatic force, or hydraulic pressure into force or torque to enable the valve core 120 to move freely or be controlled to move.

[0043] According to the water distribution valve 100 in the embodiment of the present invention, by setting that a plurality of outlets 112 are selectively connected to the inlet 111 of the valve body 110, various water outlet combinations can be realized to meet more cleaning methods and improve the user experience; by setting the driving member 130 in transmission connection with the valve core 120, the valve core 120 can rotate to control the flow rate and on / off of the fluid; by setting the driving member 130 to be offset from the inlet 111 in the axial direction of the inlet 111, the driving member 130 is not directly placed at the axial corresponding position of the inlet 111, avoiding the driving member 130 from affecting the connection between the inlet 111 and the water pump 200, and reserving a position directly below the water distribution valve 100 for the installation of the water pump 200.

[0044] Optionally, please refer to Figure 1In the projection of the axis direction of the inlet 111, the driving member 130 and the inlet 111 are arranged side by side and staggered. The central axis of the inlet 111 is parallel to the central axis of the driving member 130, but in the direction of the central axis, the projections of the driving member 130 and the inlet 111 do not overlap, that is, the position of the driving member 130 is staggered with the position of the inlet 111. The advantage of such an arrangement is that the space can be effectively utilized and it is more convenient in installation and operation.

[0045] Optionally, see Figure 1 The valve body 110 has a first side and a second side opposite to each other. Figure 1 , the first side of the valve body 110 is the lower side of the valve body 110 in the figure, the second side of the valve body 110 is the upper side of the valve body 110 in the figure, the inlet 111 is provided on the first side of the valve body 110, and the driving member 130 is installed on the first side of the valve body 110. By providing the inlet 111 on the first side of the valve body 110, it is convenient to input fluid from this side. By installing the driving member 130 on the first side of the valve body 110, it can be directly connected to the valve core 120, and the movement of the valve core 120 can be controlled by the operation of the driving member 130. In addition, by installing the inlet 111 and the driving member 130 on the same side, the number of pipeline connections can be reduced, simplifying the installation and maintenance process.

[0046] In addition, the inlet 111 can be used to connect the water pump 200. By arranging the inlet 111 and the driving member 130 on the same side, the driving member 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 the present invention can be integrated with the water cup 300. At this time, the upper side of the valve body 110 can be the inner tank, and the lower side can be a accommodating space for the water pump 200, etc. By installing the inlet 111 and the driving member 130 on the same side, the space utilization rate can be improved, and wiring can be convenient.

[0047] It should also be noted that the first side of the valve body 110 in the present invention 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 invention, and does not limit the scope of protection of the present invention.

[0048] Optionally, see Figure 1, a plurality of outlets 112 are provided on the second side of the valve body 110, and the valve core 120 is disposed 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 guided 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, playing 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 driving member 130, independent control and cross-control of the plurality of outlets 112 can be achieved, flexibly adjusting the flow direction and flow rate to meet different application requirements.

[0049] Optionally, please refer to Figure 1 , the water distribution valve 100 further includes a first gear 140, 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 driving member 130. Through the transmission connection between the first gear 140 and the driving member 130, when the driving member 130 rotates or operates, the first gear 140 will also rotate accordingly. The meshing of the first gear 140 and the second gear 121 causes the valve core 120 to move correspondingly as the first gear 140 rotates. Through this gear transmission mechanism, the movement of the driving member 130 can be converted into the movement of the valve core 120 to achieve the control of the water distribution valve 100. In addition, the gear transmission mechanism has high transmission efficiency and accuracy, and can provide stable and reliable operation control.

[0050] Optionally, the axis of the first gear 140 and the axis of the second gear 121 are parallel, enabling the first gear 140 and the second gear 121 to move on parallel axes, achieving effective transmission, and at the same time 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 be transmitted through gear meshing, transferring the movement of the driving member 130 to the valve core 120, thereby controlling the opening or closing of the water distribution valve 100.

[0051] Optionally, the tooth number ratio of the first gear 140 to the second gear 121 is less than 1, that is, the number of teeth of the first gear 140 is less than the number of teeth of 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 not to complete a full rotation when the first gear 140 has completed one full rotation, and the second gear 121 rotates slower than the first gear 140, thereby achieving a speed reduction transmission. The purpose of such a setting is to provide a more stable rotational output by reducing the rotational speed of the driving member 130.

[0052] Optionally, please refer to Figure 1, the first gear 140 includes a tooth profile portion 141, a hub 142, and a connecting portion 143. The tooth profile portion 141 surrounds the hub 142 and functions to engage and transmit force. The hub 142 is the central axis of the gear. It is connected to the tooth profile portion 141 through the connecting portion 143 and bears the force and torque transmitted by the gear. The connecting portion 143 is connected between the hub 142 and the tooth profile portion 141 and functions to fix and support. A positioning cylinder 113 is provided in the valve body 110. The positioning cylinder 113 surrounds the hub 142 and is disposed between the hub 142 and the tooth profile portion 141. The positioning cylinder 113 ensures the relative position of the tooth profile portion 141 with respect to the hub 142 is fixed to guarantee the accuracy and stability of gear transmission.

[0053] Optionally, the valve core 120 is rotatably disposed in the valve body 110, and the valve core 120 can perform a rotational movement inside the valve body 110. Please refer to Figure 1 , a communication hole 122 is provided on the valve core 120. The communication hole 122 communicates with the inlet 111 and is selectively connected to a plurality of outlets 112. Specifically, by rotating the valve core 120, the connection situation between the communication hole 122 and the inlet 111 and the outlets 112 can be adjusted, thereby controlling the distribution and guiding of the fluid. Different positions of the valve core 120 and the opening states of the communication hole 122 can achieve different flow rate and flow direction controls, can switch the fluid path, and can achieve multi-way shunting and confluence.

[0054] Optionally, please refer to Figure 1 , the plurality of outlets 112 are arranged in a circumferential pattern centered on the rotation center axis of the valve core 120. By rotating the valve core 120, the communication hole 122 can be aligned with different outlets 112, thereby controlling the flow direction of the fluid. The advantage of such a setting is that different outlets 112 can be selectively connected by rotating the valve core 120 to achieve the control of multiple fluid paths. At the same time, it also provides flexibility and can realize the layout of a plurality of outlets 112 in a smaller volume.

[0055] Optionally, the passage areas of the plurality of outlets 112 are different. The channel sizes or pore diameters of different outlets 112 are different. The difference in passage area can be used to control the flow rate distribution or variation of the fluid. Generally, the outlet 112 with a larger passage area will have a larger flow rate, while the outlet 112 with a smaller passage area will have a smaller flow rate, and the flow rate can be adjusted and controlled as needed.

[0056] Optionally, the communication holes 122 are configured to extend circumferentially along the valve core 120. In the circumferential direction of the valve core 120, the size of the communication holes 122 is greater than the minimum distance between two adjacent outlets 112, that is, the length or extension distance of the communication holes 122 exceeds the minimum distance between two adjacent outlets 112. In this way, it is ensured that when the valve core 120 rotates, the communication holes 122 are always connected to at least one outlet 112 to maintain the connectivity and stability of the fluid. By ensuring that the size of the communication holes 122 is greater than the minimum distance, it is possible to prevent the interruption or truncation of the fluid flow between the communication holes 122 and the adjacent outlets 112 during rotation, thereby ensuring the continuous smoothness of the fluid.

[0057] Optionally, the diameters of at least two outlets 112 are different. Different channel diameters or apertures of the outlets 112 can result in different flow rates or velocities. Generally, the outlet 112 with a larger diameter will have a greater flow rate or velocity, while the flow rate or velocity of the outlet 112 with a smaller diameter is also smaller. The outlets 112 with different diameters can be used to control the flow rate ratio of the fluid, adjust the flow velocity, or achieve an appropriate fluid distribution. Such a setting can be used to achieve the distribution or adjustment of the flow rate, and adjust the flow rate of different outlets 112 according to needs to meet the requirements in different modes.

[0058] Optionally, the axes of multiple outlets 112 are located on a circumference centered on the axis of the valve core 120. This layout can ensure that the position of each outlet 112 relative to the axis of the valve core 120 is equal or similar, thereby achieving a more balanced fluid distribution or control. At the same time, combined with the rotating valve core 120, more outlet 112 options can be realized, providing more fluid paths.

[0059] Optionally, please refer to Figure 1 , the valve core 120 includes a plate portion 123. The plate portion 123 is rotatably connected to the valve body 110. Communication holes 122 are provided on the plate portion 123. When a part of the communication holes 122 communicates with a part of multiple outlets 112, the plate portion 123 closes the other part of the multiple outlets 112. Taking the aforementioned three outlets as an example, when the communication holes 122 communicate with partial positions of two of the outlets, the plate portion 123 will close the remaining parts of the two outlets and the third outlet, thereby controlling the flow direction and passage of the fluid.

[0060] Optionally, the valve core 120 is configured to be adapted to simultaneously connect at least two of the multiple outlets 112 to the inlet 111, that is, the valve core 120 can simultaneously direct fluid to at least two outlets 112. Such a setting can be used to simultaneously distribute fluid to multiple spray arms docked with the outlets 112, realizing an application scenario where multiple spray arms operate simultaneously. For example, in combination with the foregoing embodiments, the valve core 120 can simultaneously direct fluid to the outlets 112 docked with the lower spray arm, upper spray arm, and top spray arm of the dishwasher, realizing a parallel process where the lower spray arm, upper spray arm, and top spray arm operate synchronously in pairs or together.

[0061] Optionally, referring to Figure 1 , the valve body 110 includes a valve seat 114 and a valve cover 115. The inlet 111 is provided on the valve seat 114; the valve cover 115 covers the valve seat 114, and multiple outlets 112 are provided on the valve cover 115. The valve core 120 is provided between the valve cover 115 and the valve seat 114. The inlet 111 is arranged on the valve seat 114 to direct fluid into the interior of the valve body 110. The valve cover 115 covers the valve seat 114 to form a sealed space. Multiple outlets 112 are provided on the valve cover 115 for distributing fluid to different pipes or devices. 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 fluid passage and flow direction. Its movement can control the on / off or distribution of fluid by rotation, enabling the valve body 110 to have flexible fluid control capabilities.

[0062] 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 can rotate around the positioning shaft. Through the cooperation of the positioning shaft and the positioning hole 124, it is ensured that the valve core 120 can maintain the correct position and direction during rotation. The positioning shaft plays a role in positioning and guiding the movement of the valve core 120, while the positioning hole 124 provides a space for cooperation with the positioning shaft.

[0063] Optionally, referring to Figure 1 , a plurality of first clamping portions 116 are provided on the periphery of the valve cover 115, and a plurality of second clamping portions 117 are provided on the outer peripheral surface of the valve seat 114. The plurality of first clamping portions 116 are respectively clamped corresponding to the plurality of second clamping portions 117. Through the corresponding clamping of the first clamping portions 116 and the second clamping portions 117, the connection between the valve cover 115 and the valve seat 114 is ensured to be stable and sealed, and at the same time, the stability and reliability of the valve body 110 during operation and use can be ensured.

The plurality of outlets 112 are respectively connected to a plurality of spray arms inside the dishwasher to ensure that the water flow can flow to each spray arm when the dishwasher is working. When the dishwasher starts to work, the water pump 200 directly introduces the water flow from the water outlet 210 of the water pump into the inlet 111 of the water distribution valve 100. At the same time, the driving member 130 operates to drive the first gear 140 of the water distribution valve 100 to rotate. The first gear 140 drives the second gear 121 to rotate. The communication holes 122 and the plate portion 123 on the second gear 121 cooperate to alternately connect or block a plurality of outlets 112 on the valve cover 115. The water flow is sprayed into the inner tank through a plurality of spray arms corresponding to the plurality of outlets 112, thereby completing the rinsing of the tableware and utensils. The design of the spray arms usually includes a rotating or deflecting function to ensure that the water flow can cover all corners of the inner tank.

[0070] According to the dishwasher in the embodiments of the present invention, by applying the water distribution valve 100 described above, the hydraulic efficiency of the entire water circuit system of the dishwasher can be improved.
