[0041] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] In order to solve the technical problem in the background technology that the cleaning branch arranged at the pump outlet of the dishwasher occupies a part of the flow output by the pump body, thereby affecting the washing efficiency, the present application provides a flow regulating valve, a flow regulating device and a dishwasher to automatically and dynamically adjust the output flow of the pump body to avoid affecting the washing efficiency.

[0043] Figure 1 The structure diagram of the flow control valve in one or more embodiments of the present application is shown. Figure 2 Shows Figure 1 The flow control valve is shown in another state. Figure 3 Shows Figure 1 The exploded diagram of the flow control valve is shown. Figure 1-Figure 3 The flow regulating valve provided in the present application includes a valve body 11 and a valve core 12. A medium interface 111 is provided at the end of the valve body 11. A first connecting portion 112 and a second connecting portion 113 are provided on the circumferential surface of the valve body 11. One end of the valve core 12 can block the medium interface 111. A reset member 13 is provided between the other end of the valve core 12 and the valve body 11. The valve core 12 is provided with a connecting portion 121. The medium injected into the valve body 1 through the medium interface 111 can push the valve core 12 to reciprocate in the valve body 1, so that the connecting portion 121 is connected to or disconnected from the first connecting portion 112 and the second connecting portion 113.

[0044] The flow regulating valve provided in the present application is provided with a medium interface 111 at the end of the valve body 11 of the flow regulating valve, so that the medium can be transported into the valve body 11 through the medium interface 111; since the first connecting portion 112 and the second connecting portion 113 are provided on the circumferential surface of the valve body 11, and the valve core 12 is provided with a connecting portion 121, the valve core 12 is movably arranged in the valve body 11, and during the movement of the valve core 12 in the valve body 11, the connecting portion 121 can be connected with the first connecting portion 112 and the second connecting portion 113, so that the medium can be output through the first connecting portion 112, the connecting portion 121 and the second connecting portion 113; since one end of the valve core 12 can block the medium interface 111, and a reset member 13 is provided between the other end of the valve core 12 and the valve body 11, the position of the valve core 12 can be automatically adjusted according to the flow rate of the medium transported into the valve body 11 by the medium interface 111, so as to control whether the medium is output through the second connecting portion 113. When the flow regulating valve is applied to the cleaning branch arranged at the outlet of the pump body 2, the flushing flow used to flush the filter element 6 can be automatically and dynamically adjusted according to the output flow of the pump body 2, so as to ensure the output flow of the pump body 2 to a certain extent to avoid affecting the washing efficiency, and has good practicality.

[0045] In the flow control valve provided in the present application, in the initial state, the valve core 12 blocks the medium interface 111 of the valve body 11, and the connecting portion 121 connects the first connection portion 112 and the second connection portion 113; when the flow rate of the medium transported from the medium interface 111 to the valve body 11 is large, the medium entering the valve body 11 through the medium interface 111 drives the valve core 12 to move in the direction of the reset member 13, the first connection portion 112 and the second connection portion 113 are disconnected, and the reset member 13 is compressed and deformed, such as Figure 1 As shown; when the flow rate of the medium transported from the medium interface 111 to the valve body 11 is small, the reset member 13 recovers its deformation and drives the valve core 12 to move toward the medium interface 111 until the valve core 12 blocks the medium interface 111 of the valve body 11, and the connecting portion 121 connects the first connecting portion 112 and the second connecting portion 113, as shown Figure 2 As shown, the output flow of the second connection portion 113 can be automatically and dynamically adjusted.

[0046] Combination Figure 1-Figure 3 In some embodiments, the valve body 11 may be roughly columnar, and the valve body 11 has a first end and a second end opposite to each other. The medium interface 111 is arranged at the first end of the valve body 11. A first connecting joint 14 may be arranged at the medium interface 111 for connecting a pipeline.

Under this condition, the connecting portion 121 on the valve core 12 penetrates the valve core 12 in the radial direction of the valve core 12 to connect the first connection portion 112 and the second connection portion 113.

[0048] In other embodiments, the first connection portion 112 and the second connection portion 113 may also be arranged at an angle on the circumference of the valve body 11, that is, the first connection portion 112 and the second connection portion 113 may be located at both ends of a certain sector-shaped circumference on the radial cross section of the valve body 11, and the angle may be 45°, 60°, 90° or 180° to adapt to different use conditions. Under this condition, the connecting portion 121 on the valve core 12 may be a straight pipe, which is offset from the central axis of the valve core 12, and its two ends are directly connected to the first connection portion 112 and the second connection portion 113 to connect the first connection portion 112 and the second connection portion 113.

[0049] It should be noted that, in other embodiments, the first connection portion 112 and the second connection portion 113 may also be located on different radial cross-sections of the valve body 11, as long as the first connection portion 112 and the second connection portion 113 of the valve body 11 can be connected by the connecting portion 121 of the valve core 12, and no limitation is made here.

[0050] In some embodiments, the first connection portion 112 and the second connection portion 113 each include more than one connection hole. When the first connection portion 112 and the second connection portion 113 are each provided with one connection hole, a pipeline can be output from the second connection portion 113. When the first connection portion 112 and the second connection portion 113 are each provided with multiple connection holes, the corresponding connection holes are connected to output multiple corresponding pipelines.

[0051] Combination Figure 1-Figure 3 In some embodiments, a second connecting joint 15 is disposed in the connecting holes of the first connecting portion 112 and the second connecting portion 113 for connecting pipelines.

[0052] Combination Figure 1-Figure 3 In some embodiments, a first guide member 114 may be provided on the inner wall of the valve body 11, and a second guide member 122 slidably matched with the first guide member 114 may be provided on the periphery of the valve core 12 to limit the moving direction of the valve core 12. One of the first guide member 114 and the second guide member 122 is a guide groove, and the other is a guide protrusion, and the guide protrusion is slidably provided in the guide groove to guide the movement of the valve core 12.

[0053] Combination Figure 1-Figure 3 In some embodiments, the first guide member 114 can be a guide groove arranged on the inner wall of the valve body 11 , and the second guide member 122 can be slidably arranged in the first guide member 114 to guide the movement of the valve core 12 .

[0054] In some embodiments, a plurality of first guide members 114 and second guide members 122 may be spaced apart around the central axis of the valve body 11, and the second guide member 122 may be slidably disposed in the corresponding first guide member 114 to guide the movement of the valve core 12 and prevent the valve core 12 from rotating when moving in the valve body 11.

[0055] In other embodiments, the guide groove provided on the inner wall of the valve body 11 may also be annular, the second guide member 122 may be a guide protrusion provided on the peripheral surface of the valve core 12, and the guide protrusion may also be annular, and the first guide member 114 is stationary, which is not limited here.

[0056] In addition, the first guide member 114 can also be a guide protrusion arranged on the inner wall of the valve body 11, and the second guide member 122 can be a guide groove arranged on the peripheral surface of the valve core 12. The first guide member 114 can be slidably arranged in the second guide member 122 to guide the movement of the valve core 12, and there is no limitation here.

[0057] It should be noted that, in the initial state, the second guide member 122 presses against the side of the first guide member 114 close to the medium interface 111 to limit the movement of the valve core 12; when the second guide member 122 presses against the side of the first guide member 114 away from the medium interface 111, the first connection part 112 and the second connection part 113 are completely offset from the connecting parts to cut off the connection between the first connection part 112 and the second connection part 113.

[0058] Combination Figure 1-Figure 2 In some embodiments, a third guide member 123 is provided at the other end of the valve core 12, and a portion of the reset member 13 is sleeved on the third guide member 123. The third guide member 123 may be columnar or block-shaped, and the reset member 13 may be a spring, which is sleeved on the third guide member 123 to guide the compression deformation of the reset member 13.

[0059] Combination Figure 1-Figure 2 In some embodiments, a first groove 124 may be provided at the other end of the valve core 12, and the third guide member 123 is gap-connected in the first groove 124, and the reset member 13 is disposed between the third guide member 123 and the side wall of the first groove 124, so that the reset member 13 has sufficient elastic deformation space to improve the deformation recovery force.

[0060] Combination Figure 1-Figure 3In some embodiments, a second groove 161 is provided at the end of the valve body 11 facing the other end of the valve core 12, and the opening sides of the second groove 161 and the first groove 124 can be arranged opposite to each other. The reset member 13 is arranged in the second groove 161 to guide the deformation of the reset member 13.

[0061] Combination Figure 1-Figure 3 In some embodiments, a valve seat 16 may be provided at the second end of the valve body 11. The valve seat 16 may be detachably assembled at the second end of the valve body 11 by means of threads or the like to facilitate the assembly of the valve core 12 and the reset member 13 in the valve body 11. The second groove 161 is arranged on the inner side of the valve seat 16.

[0062] It should be noted that the two ends of the reset member 13 can be set on the bottom of the first groove 124 and the second groove 161 in abutting manner, or can be connected to the bottom of the first groove 124 and the second groove 161 by plugging or welding, which is not limited here.

[0063] Combination Figure 1-Figure 3 In some embodiments, at least one sealing component 17 is disposed between the periphery of the valve core 12 and the inner wall of the valve body 11 to improve the sealing effect between the valve core 12 and the inner wall of the valve body 11 .

[0064] Combination Figure 1-Figure 3 In a specific implementation, two sealing components 17 may be provided around the valve core 12, and the two sealing components 17 are respectively provided on both sides of the connecting portion 121, so that when the first connecting portion 112, the connecting portion 121 and the second connecting portion 113 are connected, the medium leaks from the valve core 12 and the inner wall of the valve body 11. Each sealing component 17 may include at least one first sealing member 171, and a mounting groove 125 may be provided around the valve core 12, and the first sealing member 171 is embedded in the corresponding mounting groove 125, and at least part of the first sealing member 171 protrudes from the mounting groove 125 so as to be squeezed by the inner wall of the valve body 11 to form a seal. In other embodiments, the first sealing member 171 may also be assembled on the inner wall of the valve body 11 in the above-mentioned assembly manner, which will not be described in detail here.

[0065] Based on the above-mentioned flow regulating valve, the present application also provides a flow regulating device. Figure 4 Shows that there is Figure 1 The structural diagram of the flow regulating device shown in FIG. Figure 5 Shows that there is Figure 1 The flow regulating device is shown in the structural diagram of another state. Figure 4 as well as Figure 5The flow regulating device includes a pump body 2, a first tube body 3, a second tube body 4 and the above-mentioned flow regulating valve, wherein the output pressure of the pump body 2 is variable, the first tube body 3 is connected to the output end of the pump body 2, the medium interface 111 and the first connecting part 112 of the flow regulating valve are connected to the circumference of the first tube body 3, and the second tube body 4 is connected to the second connecting part 113 of the flow regulating valve.

[0066] In the flow regulating device provided in the present application, under the condition that the output pressure of the pump body 2 is relatively large, the medium output from the pump body 2 enters the valve body 11 through the medium interface 111 and the first connecting portion 112 in turn, and the medium entering the valve body 11 through the medium interface exerts a force on the valve core 12 to push the valve core 12 to overcome the pressure of the reset member 13 and move in the direction of the reset member 13. The first connecting portion 112 on the valve body 11 and the connecting portion 121 on the valve core 12 are not connected, and the medium is output through the first pipe body 3, as shown in FIG. Figure 4 As shown; under the condition that the output pressure of the pump body 2 is relatively low, the force exerted by the medium entering the valve body 11 through the medium interface on the valve core 12 is reduced, the reset member 13 recovers its deformation, and pushes the valve core 12 to move in the direction of the medium interface until the medium interface is blocked, the first connecting portion 112 on the valve body 11, the connecting portion 121 on the valve core 12, and the second connecting portion 113 on the valve body 11 are connected, and the medium is output through the first tube body 3 while the medium is also output through the second tube body 4, as shown in FIG. Figure 5 shown.

[0067] From the above, it can be seen that the flow regulating device provided in the present application can automatically and dynamically adjust the output of the second tube body 4 according to the delivery pressure of the pump body 2, so as to ensure the output flow of the first tube body 3 to a certain extent, and has good practicality.

[0068] Combination Figure 4-Figure 5 In some embodiments, the medium interface 111 and the first connection part 112 of the flow control valve are sequentially connected to the circumference of the first tube body 3 along the medium flow direction of the first tube body 3, that is, the medium interface 111 is located upstream of the first connection part 112. In other embodiments, the first connection part 112 may also be located upstream of the first connection part 112, which is not limited here.

[0069] Combination Figure 4 as well as Figure 5 In a specific implementation, the first tube body 3 can be connected to the first connecting joint 14 on the medium interface of the valve body 11 through the first branch pipe 31, the first tube body 3 can be connected to the second connecting joint 15 on the first connecting part 112 of the valve body 11 through the second branch pipe 32, and the second tube body 4 can be directly connected to the second connecting joint 15 on the first connecting part 112.

[0070] Based on the above flow regulating device, the present application also provides a dishwasher. Figure 6 A schematic diagram of the structure of a dishwasher in one or more embodiments of the present application is shown. Figure 7 Shows Figure 6 The structural diagram of the dishwasher shown in another state. Figure 6 as well as Figure 7 The dishwasher includes a water cup 5, a filter 6, a cleaning component 7, a spray arm assembly 9 and the above-mentioned flow regulating device, wherein the water cup 5 is used to receive clean water, the filter 6 is arranged in the water cup 5 to filter the clean water received by the water cup 5, the cleaning component 7 is arranged in the water cup 5 to clean the filter 6, the input end of the pump body 2 of the flow regulating device is connected to the water cup 5, the first pipe body 3 is connected to the spray arm assembly 9, and the second pipe body 4 is connected to the cleaning component 7.

[0071] Combination Figure 6 When the dishwasher provided by the present application is working, the clean water in the water cup 5 is filtered by the filter element 6 and then enters the pump body 2. After being pressurized by the pump body 2, the clean water enters the spray arm assembly 9 through the first pipe body 3 to wash the tableware. After being pressurized by the pump body 2, the clean water enters the valve body 11 through the medium interface 111 and the first connecting portion 112 respectively. The clean water entering the pump body 2 through the medium interface 111 pushes the valve core 12 to overcome the pressure of the reset member 13 and move in the direction of the reset member 13. The first connecting portion 112 on the valve body 11 and the connecting portion 121 on the valve core 12 are not connected, and the water flow of the clean water to the second pipe body 4 is cut off. All the clean water output by the pump body 2 enters the spray arm assembly 9 to ensure the washing effect of the tableware.

[0072] Combination Figure 7 As the contaminants on the dishes are washed off, when the clean water in the dishwasher circulates through the filter element 6, the contaminants adhere to the filter element 6, causing the water permeability of the filter element 6 to decrease, and the water intake of the pump body 2 decreases accordingly. As a result, the water pressure output by the pump body 2 decreases, and the force exerted on the valve core 12 by the clean water entering the valve body 11 through the medium interface decreases. The reset member 13 restores its deformation and pushes the valve core 12 to move toward the medium interface until the medium interface is blocked. The first connecting portion 112 on the valve body 11, the connecting portion 121 on the valve core 12, and the second connecting portion 113 on the valve body 11 are connected. While the clean water is output through the first tube body 3, it is also output to the cleaning member 7 through the second tube body 4 to clean the filter element 6.

[0073] After the pollutants on the filter element 6 are cleaned away, the water permeability of the filter element 6 increases, and the pressure output by the pump body 2 increases accordingly. Under the action of high-pressure clean water, the valve core 12 overcomes the pressure of the reset element 13 and moves again in the direction of the reset element 13. The first connecting portion 112 on the valve body 11 and the connecting portion 121 on the valve core 12 are not connected, and the flow of clean water to the second tube body 4 is cut off. All the clean water output by the pump body 2 enters the spray arm assembly 9 to ensure the washing effect of the tableware.

[0074] From the above, it can be seen that the dishwasher provided by the present application can automatically adjust the position of the valve core 12 according to the output flow of the output end of the pump body 2, and then automatically and dynamically adjust the flushing flow used to flush the filter 6. Under the condition of ensuring the cleaning effect of the filter 6, the output flow of the pump body 2 can also be guaranteed to a certain extent to avoid affecting the washing efficiency, and has good practicality.
