Technical Field

[0001] The utility model relates to the technical field of manufacturing parts of cleaning equipment, and particularly relates to a water dividing device and a cleaning equipment. Background Art

[0002] With the increasing development of technology and the improvement of living standards, especially the rapid development of household appliance technology, there are specialized dishwashing devices for tableware cleaning. A multifunctional dishwasher generally has functions such as spraying, drying, and sterilizing. Users only need to put tableware such as bowls and chopsticks into the dishwasher, and the dishwasher can automatically complete a series of cleaning tasks according to the user's settings, which is convenient to use and fully automated, effectively reducing the user's operation. Therefore, dishwashers are becoming more and more popular among thousands of households and are deeply loved by users.

[0003] For the spraying function of the dishwasher, there are generally an upper spray arm and a lower spray arm driven by water flow above or below the bowl basket, or both above and below. The upper and lower spray arms rotate and spray water at the same time to clean the tableware on the bowl basket. In the internal circulation water system of the dishwasher, in order to accurately control the water flow to the upper spray arm or the lower spray arm, a water dividing valve is generally provided in the dishwasher. The water dividing valve has two water outlets respectively communicating with the upper spray arm and the lower spray arm. A water dividing piece is provided in the water dividing valve, and the motor is used to drive the movement of the water dividing piece so that the water dividing piece blocks the corresponding water outlet, thereby realizing the control of the water output to the upper spray arm and the lower spray arm.

[0004] In the prior art, such as a water dividing valve assembly and a dishwasher with the patent number CN106151592A, which relates to the technical field of cleaning appliances. The water dividing valve assembly includes a valve seat and a valve cover buckled on the valve seat. An inlet is opened on the valve cover, and at least three outlets are opened on the valve seat. A water dividing baffle is arranged between the valve seat and the valve cover. The water dividing baffle is a disc-shaped structure with at least one through hole opened thereon. Rotating the water dividing baffle can align the through hole with different outlets on the valve seat to realize the conduction of any one or several of the at least three outlets with the inlet. At the same time, a dishwasher with the above water dividing valve assembly is proposed. The water dividing valve assembly provided by the present invention realizes the conduction and closing of any one or at least two outlets with the inlet through the rotation of the water dividing baffle, thereby realizing the functions of single-outlet water output and combined water output of multiple outlets. The structure is simple, and since the water dividing baffle adopts a disc-shaped structure, the thickness of the water dividing valve assembly is greatly reduced, and the occupied space is more saved.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0035] The embodiment of this application provides a water distribution device and a cleaning device, which can solve the problem in the prior art that the water distribution valve assembly and the dishwasher are provided with upper spray water outlets, middle spray water outlets and lower spray water outlets. The shape of the first through hole matches the outer contour formed by the upper spray water outlet and the middle spray water outlet, and the shape of the second through hole matches the shape of the lower spray water outlet. It is difficult to realize the conduction between the water outlet and the water inlet except for the upper spray water outlet at its installation position, and it is difficult to realize the conduction between any water outlet and the water inlet by rotation, thereby reducing the water outlet coverage area.

[0036] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown in, on the one hand, this application provides a water distribution device, which includes a water distribution base 1, a water distribution plate 2 and a driving mechanism 3. Among them, an accommodating cavity 13 is provided in the water distribution base 1. One end of the water distribution base 1 is provided with three water outlet holes 11 evenly spaced along the circumferential direction of the water distribution base 1. A water inlet hole 12 is provided on the side surface of the water distribution base 1. Both the water outlet hole 11 and the water inlet hole 12 are communicated with the accommodating cavity 13; the water distribution plate 2 is matched with one end of the accommodating cavity 13 close to the water outlet hole 11 and is located between the water outlet hole 11 and the water inlet hole 12.

[0037] When using the device for water distribution, the water distribution plate 2 is matched with one end of the accommodation cavity 13 close to the water outlet hole 11 and is arranged between the water outlet hole 11 and the water inlet hole 12. The driving mechanism 3 is used to drive the water distribution plate 2 to rotate so as to align any one or any two of at least three water outlet holes 11 with the through-flow holes 21, and make the other through-flow holes 21 located in the area between adjacent water outlet holes 11. Since one end of the water distribution seat 1 is provided with three water outlet holes 11 evenly spaced along the circumferential direction of the water distribution seat 1, and the water distribution plate 2 is provided with three through-flow holes 21, the driving mechanism 3 drives the water distribution plate 2 to rotate so as to align any one or any two of the three water outlet holes 11 with the through-flow holes 21, and make the other through-flow holes 21 located in the area between adjacent water outlet holes 11, which can ensure that any one or any two of the three water outlet holes 11 are aligned with the through-flow holes 21, with a more stable structure and a larger water outlet coverage area, solving the problem in the prior art that for the water distribution valve assembly and the dishwasher with an upper spray water outlet, a middle spray water outlet and a lower spray water outlet, the shape of the first through-hole matches the outer contour formed by the upper spray water outlet and the middle spray water outlet, the shape of the second through-hole matches the shape of the lower spray water outlet, and it is difficult to realize the conduction between the water inlet and the water outlet other than the upper spray water outlet, and it is difficult to realize the conduction between any water outlet and the water inlet by rotation, thus reducing the water outlet coverage area.

[0038] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, in some alternative embodiments, the triangle formed by the axial center connection lines of two adjacent water outlet holes 11 is an equilateral triangle. Among the three through-flow holes 21 on the water distribution plate 2, two through-flow holes 21 are arranged corresponding to the water outlet holes 11, and the other through-flow hole 21 is symmetrically arranged with one of the correspondingly arranged through-flow holes 21 along the perpendicular line passing through the center of the equilateral triangle.

[0039] In this embodiment, the triangle formed by the axial center connection lines of two adjacent water outlet holes 11 is an equilateral triangle. Among the three through-flow holes 21 on the water distribution plate 2, two through-flow holes 21 are arranged corresponding to the water outlet holes 11, and the remaining through-flow hole 21 is symmetrically arranged with one of the correspondingly arranged through-flow holes 21 along the perpendicular line passing through the center of the equilateral triangle, that is, the axial center connection line of the remaining through-flow hole 21 and one of the correspondingly arranged through-flow holes 21 passes through the perpendicular line of the center of the equilateral triangle, which illustrates the specific position of the through-flow holes 21 and ensures that any one or any two of the three water outlet holes 11 are aligned with the through-flow holes 21.

[0040] As Figure 1 , Figure 2 and Figure 3As shown, in some alternative embodiments, the water distribution base 1 includes a water distribution base housing 14 and a water distribution base lower cover 15. Among them, the water distribution base housing 14 is provided with a water outlet hole 11 and a water inlet hole 12; the water distribution base lower cover 15 is detachably connected to the water distribution base housing 14 and cooperates to form a receiving cavity 13, and the water distribution base lower cover 15 is connected to the driving mechanism 3.

[0041] In this embodiment, the specific structure of the water distribution base 1 is specifically described. The water distribution base 1 includes a water distribution base housing 14 and a water distribution base lower cover 15. Among them, the water distribution base housing 14 is provided with a water outlet hole 11 and a water inlet hole 12. The water distribution base lower cover 15 is detachably connected to the water distribution base housing 14 and cooperates to form a receiving cavity 13. The water distribution base lower cover 15 is connected to the driving mechanism 3. The structure is simple and it is convenient to install the water distribution plate 2.

[0042] In this example, the water distribution base housing 14 is a two-color injection molding structure of plastic and rubber parts. When installed, the rubber part on the water outlet hole 11 can play a sealing role, and there is no need to additionally assemble other sealing structural parts, and the assembly is simple.

[0043] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some alternative embodiments, the water distribution base lower cover 15 is provided with a mounting through hole. The driving mechanism 3 includes a transmission shaft 31 and a driving motor 32. Among them, the transmission shaft 31 passes through the mounting through hole and extends into the receiving cavity 13 and is connected to the water distribution plate 2; the driving motor 32 is arranged outside the water distribution base lower cover 15 and is connected to the transmission shaft 31. The driving motor 32 is used to drive the transmission shaft 31 to rotate so as to drive the water distribution plate 2 to rotate.

[0044] In this embodiment, the structure of the driving mechanism 3 is specifically described. The driving mechanism 3 includes a transmission shaft 31 and a driving motor 32. Among them, the transmission shaft 31 passes through the mounting through hole and extends into the receiving cavity 13 and is connected to the middle part of the water distribution plate 2. The connection point is actually located on the perpendicular line of the midpoint of the equilateral triangle formed by the axis connection line of two adjacent water outlet holes 11. The driving motor 32 is arranged outside the water distribution base lower cover 15 and is connected to the transmission shaft 31. The driving motor 32 is used to drive the transmission shaft 31 to rotate so as to drive the water distribution plate 2 to rotate. The structure is simple and it is convenient to manufacture.

[0045] In this example, an X-shaped sealing ring 8 is provided on the transmission shaft 31 for sealing the gap between the transmission shaft 31 and the water distribution base lower cover 15.

[0046] As Figure 3 and Figure 4As shown, in some alternative embodiments, a cam structure 312 is sleeved on the transmission shaft 31. A microswitch 5 is provided on the side of the drive motor 32 close to the transmission shaft 31. The microswitch 5 cooperates with the cam structure 312. When the drive motor 32 drives the transmission shaft 31 to rotate, the transmission shaft 31 drives the cam structure 312 to rotate. The cam structure 312 touches the microswitch 5, and the microswitch 5 is used to record the number of rotations of the cam structure 312.

[0047] In this embodiment, a cam structure 312 is sleeved on the transmission shaft 31. A microswitch 5 is provided on the side of the drive motor 32 close to the transmission shaft 31. The microswitch 5 cooperates with the cam structure 312. When the drive motor 32 drives the transmission shaft 31 to rotate, the transmission shaft 31 drives the cam structure 312 to rotate. The cam structure 312 touches the microswitch 5, and the microswitch 5 is used to record the number of rotations of the cam structure 312. By the initial positions of the three through-flow holes 21 on the water distribution plate 2 and the real-time number of rotations of the cam structure 312, the real-time positions of the three through-flow holes 21 can be determined to determine the connected water outlet holes 11.

[0048] As Figure 3 and Figure 4 shown, in some alternative embodiments, a fixing member 6 is provided on the side of the drive motor 32 close to the transmission shaft 31. The fixing member 6 is used to mount the microswitch 5 and the cam structure 312.

[0049] In this embodiment, a fixing member 6 is provided on the side of the drive motor 32 close to the transmission shaft 31. The fixing member 6 is used to mount the microswitch 5 and the cam structure 312, which facilitates connecting the microswitch 5 and determining the positions of the microswitch 5 and the cam structure 312, so that when the transmission shaft 31 drives the cam structure 312 to rotate, the cam structure 312 touches the microswitch 5.

[0050] In this example, an O-ring 7 is provided between the fixing member 6 and the lower cover 15 of the water distribution seat.

[0051] As Figure 3 and Figure 5 shown, in some alternative embodiments, an installation round platform 151 and a water guiding platform 152 arranged around the installation round platform 151 are provided inside the lower cover 15 of the water distribution seat. The installation round platform 151 is used for the transmission shaft 31 to pass through. The lower side of the water guiding platform 152 corresponds to the water inlet hole 12. When water enters from the water inlet hole 12, the water flows along the water guiding platform 152 from the lower side of the water guiding platform 152.

[0052] In this embodiment, an installation round platform 151 and a water guide platform 152 arranged around the installation round platform 151 are provided inside the lower cover 15 of the water separation seat. The installation round platform 151 is used for the transmission shaft 31 to pass through. The lower side of the water guide platform 152 corresponds to the water inlet hole 12. When water enters through the water inlet hole 12, the water flow moves along the water guide platform 152 from the lower side of the water guide platform 152, reducing the flow resistance of the water flow and making the water outlet smoother.

[0053] As Figure 3 , Figure 4 and Figure 5 shown, in some alternative embodiments, a butting round platform 311 is provided on the transmission shaft 31. The butting round platform 311 is used for butting against the installation round platform 151.

[0054] In this embodiment, a butting round platform 311 is provided on the transmission shaft 31. The butting round platform 311 is used for butting against the installation round platform 151, which is convenient for determining the installation position of the transmission shaft 31.

[0055] As Figure 3 and Figure 5 shown, in some alternative embodiments, a spring 4 is provided on the side of the butting round platform 311 away from the installation round platform 151. One end of the spring 4 is connected to the butting round platform 311, and the other end is connected to the water separation plate 2. The spring 4 is used for providing an elastic force to move the water separation plate 2 towards the end of the accommodation cavity 13 close to the water outlet hole 11.

[0056] In this embodiment, a spring 4 is provided on the side of the butting round platform 311 away from the installation round platform 151. One end of the spring 4 is connected to the butting round platform 311, and the other end is connected to the water separation plate 2. The spring 4 is used for providing an elastic force to move the water separation plate 2 towards the end of the accommodation cavity 13 close to the water outlet hole 11. The spring 4 presses the water separation plate 2 against the end of the accommodation cavity 13 close to the water outlet hole 11, enhancing the sealing effect.

[0057] In this example, the transmission shaft 31 and the water separation plate 2 are movable in the axial direction of the transmission shaft 31, and the transmission shaft 31 can drive the water separation plate 2 to rotate.

[0058] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, on the other hand, the present application also provides a cleaning device, which includes the above-mentioned device for water separation.

[0059] When using the device for water diversion, the water diversion plate 2 is matched with one end of the accommodation cavity 13 close to the water outlet hole 11 and is arranged between the water outlet hole 11 and the water inlet hole 12. The driving mechanism 3 is used to drive the water diversion plate 2 to rotate so as to align any one or any two of at least three water outlet holes 11 with the through-flow holes 21, and make the other through-flow holes 21 located in the area between adjacent water outlet holes 11. Since one end of the water diversion base 1 is provided with three water outlet holes 11 evenly spaced along the circumferential direction of the water diversion base 1, and the water diversion plate 2 is provided with three through-flow holes 21, the driving mechanism 3 drives the water diversion plate 2 to rotate so as to align any one or any two of the three water outlet holes 11 with the through-flow holes 21, and make the other through-flow holes 21 located in the area between adjacent water outlet holes 11, which can ensure that any one or any two of the three water outlet holes 11 are aligned with the through-flow holes 21, with a more stable structure and a larger water outlet coverage area, solving the problem in the prior art that the water diversion valve assembly and the dishwasher are provided with an upper spray water outlet, a middle spray water outlet and a lower spray water outlet, the shape of the first through-hole matches the outer contour jointly formed by the upper spray water outlet and the middle spray water outlet, the shape of the second through-hole matches the shape of the lower spray water outlet, and it is difficult to realize the conduction between the water inlet and the water outlet other than the upper spray water outlet at its set position, and it is difficult to realize the conduction between any water outlet and the water inlet by rotation, thereby reducing the water outlet coverage area.
