Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a water diversion valve, a water diversion device and a dishwasher. Background Art

[0002] Most existing dishwashers lack a water diverter valve. Those that do have a complex water diverter valve structure require a position detection device to monitor the position of the diverter plate to achieve water diversion. Because the detection device needs to provide feedback to the main control board before the motor can stop, there's a delay, which can cause the diverter plate to deviate from its stop position and affect water diversion. A malfunctioning detection device can lead to water diversion failure, seriously impacting the dishwasher's performance. Summary of the Invention

[0003] The purpose of the present invention is to provide a water diversion valve, a water diversion device and a dishwasher, which can ensure the accuracy of the stop position of the water diversion plate, reduce the phenomenon of the water diversion valve being stuck or blocked, and avoid water leakage problems.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] In a first aspect, the present invention provides a water diverter valve, comprising a water diverter valve body, a paddle, a water diverter plate, a magnetic assembly, and an electromagnetic assembly;

[0006] The paddle and the water diverter are both rotatably disposed in the water diverter valve body, and the paddle and the water diverter are spaced apart from each other.

[0008] The electromagnetic component is installed on the water diversion valve body and the water diversion plate to stop the water diversion plate. The magnetic force of the electromagnetic component is greater than the magnetic force of the magnetic attraction component.

[0009] Furthermore, the electromagnetic assembly includes a metal block mounted on the water diversion plate and a plurality of electromagnets correspondingly mounted on the valve body of the water diversion valve;

[0010] When the water dividing plate stops rotating, the metal block is attracted to one of the electromagnets.

[0011] Furthermore, the magnetic attraction assembly includes a first magnet installed on the paddle and a second magnet correspondingly installed on the water diversion plate.

[0012] Furthermore, the water diversion plate includes a linkage disk, a water diversion disk and a connecting shaft, and the linkage disk is connected to the water diversion disk via the connecting shaft;

[0013] The magnetic attraction component is installed on the linkage disk, and the linkage disk is rotatably matched with the valve body of the water diversion valve;

[0014] The electromagnetic assembly is installed on the water diversion plate, and the water diversion plate has a water diversion hole group.

[0015] Furthermore, the water diversion hole group includes a water diversion hole, and when the water diversion plate stops rotating, the water diversion hole is used to guide the water flow in the valve body of the water diversion valve into at least one water channel;

[0016] Alternatively, the water diversion hole group includes a plurality of water diversion holes, and when the water diversion plate stops rotating, each of the water diversion holes is used to direct the water flow in the valve body of the water diversion valve into a waterway.

[0017] Furthermore, the water diversion hole group includes one water diversion hole, which is in a waist-shaped structure. When the water diversion plate stops rotating, the water diversion hole is used to simultaneously guide the water flow in the water diversion valve body into multiple water channels.

[0018] Furthermore, the water diversion valve body has a first installation cavity and a second installation cavity which are separately arranged;

[0019] The paddle is rotatably disposed in the first installation cavity, and the water-dividing piece is rotatably disposed in the second installation cavity.

[0020] Furthermore, the first mounting cavity has a first annular groove, and the bottom of the paddle is rotatably disposed in the first annular groove;

[0021] The second installation cavity has a second annular groove, and the top of the water dividing plate is rotatably arranged in the second annular groove.

[0022] Furthermore, the water diversion valve also includes a main control board connected to the multiple electromagnets, and the main control board is used to control the power supply status of the multiple electromagnets so that the water diversion holes on the water diversion plate are connected to the water channels corresponding to the energized electromagnets.

[0023] Furthermore, the water diversion valve further includes a driving mechanism installed on the valve body of the water diversion valve, and the driving mechanism is connected to the paddle to drive the paddle to rotate.

[0024] In a second aspect, the present invention further provides a water diversion device, comprising a water tank and the water diversion valve described in the above solution;

[0025] The water tank has a plurality of water diversion ports, each of which corresponds to a waterway;

[0026] The water diversion valve body is installed on the water tank, and the water diversion valve body is provided with a water inlet;

[0027] The water dividing plate is rotatably connected to the water trough, and the water inlet is communicated with any one of the water dividing ports through the water dividing plate.

[0028] Furthermore, one of the water trough and the water dividing plate is provided with a concave point, and the other of the water dividing plate and the water trough is provided with a convex point that rotates with the concave point.

[0029] Furthermore, the water diversion device also includes a first tube body, a washing pump and a second tube body, the water inlet end of the washing pump is connected to the second tube body, the water outlet end of the washing pump is connected to the first tube body, and the end of the first tube body away from the washing pump is connected to the water inlet of the water diversion valve body.

[0030] In a third aspect, the present invention further provides a dishwasher comprising the water separation device described in the above solution.

[0031] The water diversion valve, water diversion device, and dishwasher provided by the present invention can produce the following beneficial effects:

[0032] When using the above-mentioned water diverter valve, the paddle rotates relative to the water diverter valve body. Under the action of the magnetic component, the water diverter plate rotates synchronously with the paddle. When the electromagnetic component is energized, the electromagnetic component generates magnetic force. Since the magnetic force of the electromagnetic component is greater than the magnetic force of the magnetic component, the water diverter valve body attracts the rotating water diverter plate, and the water diverter plate stops rotating and will not continue to rotate with the paddle, so that the water diverter plate stops accurately at the set position.

[0033] Compared with the existing technology, on the one hand, the water diversion valve provided by the first aspect of the present invention eliminates the position detection device of the water diversion plate, and stops the water diversion plate at the set position through the electromagnetic component. The stopping of the water diversion plate is not affected by the driving mechanism, which fundamentally solves the problem of position deviation of the water diversion plate caused by the need for the position detection device to communicate with the mainboard control and the failure of the driving mechanism, and ensures the accuracy of the stopping position of the water diversion plate; on the other hand, the water diversion valve provided by the second aspect of the present invention uses magnetic force to realize the linkage between the paddle and the water diversion plate, eliminating the mechanical connection structure between the two, and will not cause the water diversion valve to get stuck or stalled due to assembly interference caused by the size deviation of the transmission mechanism. At the same time, the sealing design of the connection is reduced, which fundamentally solves the problem of water leakage caused by insufficient sealing at the connection in the traditional structure.

[0034] Compared to the prior art, the water diversion device provided in the second aspect of the present invention comprises a water tank and the aforementioned water diversion valve. By controlling the power supply status of an electromagnetic assembly, the communication between the water inlet and each water diversion port is controlled, eliminating the traditional method of controlling the rotation and stopping of the water diversion plate through a drive mechanism. This water diversion device fundamentally addresses the problem of positional deviation of the water diversion plate caused by the position detection device's need to communicate with the main control board and failure of the drive mechanism. The water diversion valve is immune to jamming and stalling, and exhibits excellent sealing properties.

[0035] Compared with the prior art, the dishwasher provided in the third aspect of the present invention has the water separation device provided in the second aspect of the present invention, and thus has all the beneficial effects of the water separation device provided in the second aspect of the present invention.

DETAILED DESCRIPTION

[0054] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0056] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0058] The embodiment of the first aspect of the present invention is to provide a water diverter valve, such as Figure 1 As shown, it includes a water diverter valve body 1, a paddle 3, a water diverter plate 4, a magnetic assembly 5 and an electromagnetic assembly 6; the paddle 3 and the water diverter plate 4 are both rotatably arranged in the water diverter valve body 1, and the paddle 3 and the water diverter plate 4 are relatively spaced apart; the magnetic assembly 5 is installed on the paddle 3 and the water diverter plate 4 to realize the linkage between the paddle 3 and the water diverter plate 4; the electromagnetic assembly 6 is installed on the water diverter valve body 1 and the water diverter plate 4 to realize the stoppage of the water diverter plate 4, and the magnetic force of the electromagnetic assembly 6 is greater than the magnetic force of the magnetic assembly 5.

[0059] When in use, under the action of the magnetic component 5, the water-dividing piece 4 rotates synchronously with the paddle 3. Figure 2 As shown, when the electromagnetic component 6 is energized, the electromagnetic component 6 generates magnetic force. Since the magnetic force of the electromagnetic component 6 is greater than the magnetic force of the magnetic attraction component 5, the water diversion valve body 1 attracts the rotating water diversion plate 4, and the water diversion plate 4 stops rotating and no longer rotates with the paddle 3, so that the water diversion plate 4 stops accurately at the set position.

[0060] The water diversion valve provided in the embodiment of the first aspect of the present invention uses the electromagnetic component 6 to stop the water diversion plate 4 at the set position, which is not affected by the driving mechanism. It fundamentally solves the problem of position deviation of the water diversion plate 4 caused by the need for the position detection device to communicate with the main board control and the failure of the driving mechanism 2, thereby ensuring the accuracy of the stopping position of the water diversion plate; in addition, by utilizing the non-direct contact characteristics of the magnetic force, the mechanical connection structure between the paddle 3 and the water diversion plate 4 is eliminated, and there will be no jamming, blocking and leakage caused by the mechanical connection.

[0061] It should be noted that any structure that can stop the water-dividing plate 4 can be the electromagnetic assembly 6 mentioned in the above embodiment. For example, the electromagnetic assembly 6 can include an electromagnet and an iron block, or an electromagnet and a nickel-cobalt alloy block, etc.

[0062] In some embodiments, as Figure 2 As shown, the electromagnetic assembly 6 includes a metal block 61 mounted on the water diversion plate 4 and a plurality of electromagnets 62 correspondingly mounted on the water diversion valve body 1; when the water diversion plate 4 stops rotating, the metal block is attracted to an electromagnet.

[0063] When a particular electromagnet 62 is energized, it attracts the metal block 61 on the water diverter plate 4 in the transmission state. This suction force causes the water diverter plate 4 to remain stationary at a fixed position, directing the water flow within the water diverter valve body 1 to the corresponding waterway. Therefore, the user can control the energization state of each electromagnet 62 to change the position where the water diverter plate 4 is suspended, thereby switching the connection between the water diverter plate 4 and the various waterways.

[0064] It should be noted that, in each switching, only one electromagnet 62 is in the energized state, so that the position where the water dividing plate 4 is paused is uniquely determined.

[0065] The number of electromagnets 62 is related to the number of water diversion ports 71 on the water tank 7. Specifically, the number of electromagnets 62 and the number of water diversion ports 71 on the water tank 7 are in a one-to-one correspondence, that is, one electromagnet 62 corresponds to one water diversion port 71. When the metal block 61 is attracted to a certain electromagnet 62, the water diversion plate 4 can guide the water flow in the water diversion valve body 1 to the water diversion port 71 corresponding to the electromagnet 62. Figure 1 As shown, when the number of the water diversion ports 71 is three, the number of the electromagnets 62 is three.

[0066] There are many ways to install the electromagnet 62 and the water diversion valve body 1, and to install the metal block 61 and the water diversion plate 4, specifically, bonding, embedding, etc.

[0067] In at least one embodiment, Figure 1 and Figure 2 As shown, the electromagnet 62 is embedded in the water diversion valve body 1; the metal block 61 is embedded in the water diversion plate 4. The above arrangement can prevent the electromagnet 62 and the metal block 61 from protruding from the surface of the water diversion valve body 1 and the water diversion plate 4, and the installation of the electromagnetic assembly 6 is more secure.

[0068] Specifically, if Figure 3 As shown, the water diverter valve body 1 is provided with a plurality of slots 14, which are recessed in the outer surface of the water diverter valve body 1, and the center of the circle formed by the center line of the plurality of slots 14 passes through the axis of the water diverter valve body 1. Figure 3 In the direction of the card slot 14, the card slot 14 has a mounting opening opening upward, and each electromagnet 62 is installed in a card slot 14 through the mounting opening.

[0069] In addition, the plurality of slots 14 may be evenly distributed around the axis of the water diversion valve body 1 , or may be unevenly distributed around the axis of the water diversion valve body 1 according to the distribution of the water channels.

[0070] Specifically, if Figure 4 As shown, the water diverter plate 4 is provided with a third mounting groove 423 , in which the metal block 61 can be embedded. After assembly, the metal block 61 can be attracted by any electromagnet 62 to stop the water diverter plate 4 .

[0071] The working principle of the electromagnetic component 6 is described in detail below:

[0072] by Figures 5 to 8 For example, there are three electromagnets 62 on the water diverter valve body 1. Figure 5 In the counterclockwise direction, three electromagnets 62 are set as the first electromagnet, the second electromagnet and the third electromagnet. The first electromagnet is the electromagnet on the far left. When the first electromagnet is energized, the metal block 61 is attracted by the first electromagnet due to the magnetic force, and the water-dividing plate 4 is stationary. Figure 6 When the second electromagnet is energized, the metal block 61 is attracted by the second electromagnet due to the magnetic force, and the water-dividing plate 4 is stationary. Figure 7 When the third electromagnet is energized, the metal block 61 is attracted by the third electromagnet due to the magnetic force, and the water-dividing plate 4 is stationary. Figure 8 , the water flows out from the water diversion port 71 corresponding to the water diversion hole 421.

[0073] In some embodiments, as Figure 1 As shown, the magnetic component 5 includes a first magnet 51 installed on the paddle 3 and a second magnet 52 correspondingly installed on the water-dividing plate 4. When in use, the first magnet 51 and the second magnet 52 attract each other to achieve the linkage between the paddle 3 and the water-dividing plate 4. Among them, the size relationship between the first magnet 51 and the second magnet 52 is not specifically limited, and can be adaptively adjusted according to different situations. Preferably, the cross-sectional diameter of the first magnet 51 is equal to the cross-sectional diameter of the second magnet 52. In addition, the shape of the magnetic component 5 is not specifically limited, for example, circular, elliptical, triangular and other shapes are applicable.

[0074] The first magnet 51 and the second magnet 52 can be installed in various ways, specifically by bonding, embedding, etc. In at least one embodiment, the first magnet 51 is embedded in the paddle 3 ; the second magnet 52 is embedded in the water-dividing plate 4 .

[0075] Specifically, if Figure 9 As shown, the pick 3 is provided with a first placement groove 32, and the first magnet 51 can be embedded in the first placement groove 32. Figure 10As shown, a second placement groove 411 is provided at a corresponding position of the water dividing plate 4, and the second magnet 52 can be embedded in the second placement groove 411. After assembly, the first magnet 51 and the second magnet 52 are positioned correspondingly and play a role of attraction.

[0076] In addition, if Figure 9 As shown, the paddle 3 is disc-shaped, and its circumferential outer surface extends in an arc shape. One side of the paddle 3 is provided with a motor fixing groove 31 for plugging with the power output shaft 21 of the driving mechanism 2 and a first placement groove 32 for installing the first magnet 51.

[0077] In some embodiments, as Figure 10 and Figure 11 As shown, in order to prevent the magnetic component 5 and the electromagnetic component 6 on the water diversion plate 4 from interfering with each other, the water diversion plate 4 includes a linkage disk 41, a water diversion disk 42 and a connecting shaft 43, and the linkage disk 41 is connected to the water diversion disk 42 through the connecting shaft 43; the magnetic component 5 is installed on the linkage disk 41, and the linkage disk 41 rotates with the water diversion valve body 1; the electromagnetic component 6 is installed on the water diversion disk 42, and the water diversion disk 42 has a water diversion hole group, which is used to guide the water flow in the second installation cavity 12 to at least one waterway.

[0078] Specifically, if Figure 10 As shown, the linkage disk 41 is provided with a second placement groove 411 for mounting the magnet in the second magnet 52 ; the water separation disk 42 is provided with a third mounting groove 423 for mounting the metal block 61 .

[0079] Preferably, the opening of the second placement groove 411 is located on the side of the linkage disk 41 away from the paddle 3, and the opening of the third installation groove 423 is located on the side of the water diversion disk 42 away from the paddle 3. Under the action of magnetic force, the second magnet 52 in the second placement groove 411 and the metal block 61 in the third installation groove 423 can be more firmly embedded in the water diversion plate 4, that is, the second magnet 52 and the metal block 61 will not have a tendency to separate from the water diversion plate 4.

[0080] In some other embodiments, the second placement groove 411 and the third installation groove 423 can also be through grooves with openings at both ends, or the opening of the second placement groove 411 is located on the side of the linkage disk 41 facing the paddle 3, and the opening of the third installation groove 423 is located on the side of the water diversion disk 42 facing the paddle 3.

[0081] In some embodiments, as Figures 10 to 12As shown, in order to enable the water diversion hole group to direct the water flow in the second installation cavity 12 into one or more waterways, the water diversion hole group may include a water diversion hole 421. When the water diversion plate 4 stops rotating, the water diversion hole 421 is used to direct the water flow in the water diversion valve body 1 into at least one waterway; the water diversion hole group may also include multiple water diversion holes 421. When the water diversion plate 4 stops rotating, each water diversion hole 421 is used to direct the water flow in the water diversion valve body 1 into one waterway.

[0082] According to the structural type of the water diversion hole group, it can be divided into the following three embodiments.

[0083] Example 1:

[0084] like Figure 10 As shown, the water diversion hole group includes two water diversion holes 421. When the water diversion plate 4 stops rotating, each water diversion hole 421 is connected to only one water channel to simultaneously guide the water flow in the second installation cavity 12 into the two corresponding water channels. The shape of the water diversion hole 421 can be a circle corresponding to the water diversion port 71 on the water tank 7.

[0085] Example 2:

[0086] like Figure 11 As shown, the water diversion hole group includes a water diversion hole 421. When the water diversion plate 4 stops rotating, the water diversion hole 421 is only connected to one water channel to guide the water flow in the second installation cavity 12 into a corresponding water channel. The shape of the water diversion hole 421 can be a circle corresponding to the water diversion port 71 on the water tank 7.

[0087] Example 3:

[0088] like Figure 12 As shown, the water diversion hole group includes a water diversion hole 421, which has a waist-shaped structure. When the water diversion plate 4 stops rotating, the water diversion hole 421 is connected to multiple water channels to simultaneously guide the water flow in the second installation cavity 12 into the corresponding multiple water channels.

[0089] Of course, the structural types of the water diversion hole group are not limited to the above three types, and a combination of any two or all of the above embodiments can be adopted according to actual needs.

[0090] In some embodiments, as Figure 2 As shown, the water diverter valve body 1 has a first mounting cavity 11 and a second mounting cavity 12, which are separated. The paddle 3 is rotatably disposed in the first mounting cavity 11, and the water diverter 4 is rotatably disposed in the second mounting cavity 12. The first and second mounting cavities 11 and 12 separate the paddle 3 and the water diverter 4. The paddle 3 and the water diverter 4 are not mechanically connected, eliminating the need for a seal at the connection and preventing insufficient sealing.

[0091] Specifically, if Figure 13As shown, the water diverter valve body 1 has a partition plate 15 , which divides the water diverter valve body 1 into a first installation cavity 11 and a second installation cavity 12 .

[0092] like Figure 3 As shown, the first mounting cavity 11 has a first annular groove 111, and the bottom of the paddle 3 is rotatably disposed in the first annular groove 111; Figure 13 As shown, the second mounting cavity 12 has a second annular groove 121, and the top of the water diverter plate 4 is rotatably disposed in the second annular groove 121. The above arrangement allows the paddle 3 and the water diverter plate 4 to rotate more stably relative to the water diverter valve body 1.

[0093] During assembly, the bottom of the paddle 3 extends into the first annular groove 111 and is rotatably connected thereto. The bottom of the linkage disk 41 in the water diverter 4 extends into the second annular groove 121 and is rotatably connected thereto. The first annular groove 111 and the second annular groove 121 reduce the contact area between the paddle 3 and the water diverter valve body 1, and between the water diverter 4 and the water diverter valve body 1. This not only reduces friction but also acts as a limiter, ensuring that the paddle 3 and the water diverter 4 do not tilt during rotation.

[0094] like Figure 14 As shown, a rib 33 is provided at the bottom of the paddle 3 for extending into the first annular groove 111 .

[0095] Specifically, the first annular groove 111 and the second annular groove 121 are respectively located on both sides of the partition plate 15 on the water diversion valve body 1 .

[0096] In some embodiments, the water diverter valve further includes a driving mechanism 2 mounted on the water diverter valve body 1 , and the driving mechanism 2 is connected to the paddle 3 for driving the paddle 3 to rotate.

[0097] It should be noted that any structure capable of driving the paddle 3 to rotate can be the driving mechanism 2 mentioned in the above embodiment. For example, the driving mechanism 2 includes a motor, or the driving mechanism 2 includes an impeller, etc.

[0098] In at least one embodiment, Figure 15 As shown, the driving mechanism 2 can be a motor having a power output shaft 21 .

[0099] The motor fixing groove 31 adopts the same shape as the power output shaft 21 to prevent incorrect direction assembly.

[0100] Specifically, the linkage disk 41 is disposed near the top of the second installation cavity 12. Figure 11 As shown, a rib 412 for extending into the second annular groove 121 is provided on one side of the linkage disk 41 facing the top of the second mounting cavity 12 .

[0101] In some embodiments, the water diversion valve also includes a main control board connected to the multiple electromagnets 62, which is used to control the power status of the multiple electromagnets 62 so that the water diversion holes 421 on the water diversion plate 4 are connected to the water channels corresponding to the energized electromagnets 62.

[0102] During use, the user can control a certain electromagnet 62 to be energized through the main control panel. The electromagnet 62 attracts the metal block 61, causing the water diverter plate 4 to stop rotating with the paddle 3. At this time, the water diverter hole 421 on the water diverter plate 4 is connected to the water path corresponding to the electromagnet 62.

[0103] The embodiment of the second aspect of the present invention is to provide a water separation device, such as Figure 1 and Figure 2 As shown, the water diversion device provided by the embodiment of the second aspect of the present invention includes a water tank 7 and the above-mentioned water diversion valve; the water tank 7 has multiple water diversion ports 71, and each water diversion port 71 corresponds to a water channel; the water diversion valve body 1 is installed on the water tank 7, and the water diversion valve body 1 is provided with a water inlet 13; the water diversion plate 4 is rotatably connected to the water tank 7, and the water inlet 13 is connected to any one of the water diversion ports 71 through the water diversion plate 4.

[0104] Compared with the prior art, the water diversion device provided in the embodiment of the second aspect of the present invention has a water tank 7 and the above-mentioned water diversion valve. By controlling the power-on state of the electromagnetic component 6, the connection state between the water inlet 13 and each water diversion port 71 is controlled, and the traditional method of controlling the rotation and stop of the water diversion plate 4 by the driving mechanism 2 is broken away. It fundamentally solves the problem of position deviation of the water diversion plate caused by the need for the position detection device to communicate with the mainboard control and the failure of the driving mechanism 2, and there will be no jamming, blocking and leakage caused by mechanical connection.

[0105] The water diverter valve body 1 can be connected to the water tank 7 by threads or by screws or other connecting parts. There are many ways to connect them, which are not specifically limited here. To ensure good sealing, a sealing ring 011 is provided between the water diverter valve body 1 and the water tank 7.

[0106] In at least one embodiment, the water tank 7 has three water diversion ports 71 . The electromagnetic assembly includes the same number of electromagnets 62 as the water diversion ports 71 .

Figure 10As shown, the water diverter plate 4 has a convex point 422 that cooperates with the concave point 72. In other embodiments, the water diverter plate 4 has a concave point, and the water trough 7 has a convex point that cooperates with the concave point. The cooperation between the concave point 72 and the convex point 422 can reduce the contact area between the water trough 7 and the water diverter plate 4, reducing friction during rotation.

[0108] In some embodiments, as Figure 16 As shown, the water diversion device also includes a first tube body 8, a washing pump 9, and a second tube body 10. The water inlet end of the washing pump 9 is connected to the second tube body 10, and the water outlet end of the washing pump 9 is connected to the first tube body 8. The end of the first tube body 8 away from the washing pump 9 is connected to the water inlet 13 of the water diversion valve body 1. Specifically, the water in the second tube body 10 enters the washing pump 9 and is discharged into the second installation cavity 12 of the water diversion valve body 1 through the first tube body 8. Under the water diversion action of the water diversion valve, the water can flow out of the set water diversion port 71, thereby achieving the effect of distributing the water flow to the set waterway branches.

[0109] An embodiment of a third aspect of the present invention provides a dishwasher. The dishwasher provided by the embodiment of the second aspect of the present invention includes the above-mentioned water diversion device.

[0110] Compared with the prior art, the dishwasher provided by the embodiment of the third aspect of the present invention has the water separation device provided by the embodiment of the second aspect of the present invention, and thus has all the beneficial effects of the water separation device provided by the embodiment of the second aspect of the present invention.
