In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] This embodiment provides a water separation structure that can be used in a dishwasher. On the basis of improving the utilization space of the inner barrel 400, the pressure loss can be small and the cleaning effect is better. Figures 1 to 6 As shown, the water diversion structure includes a water cup 100 and a water diversion valve assembly 200 .

[0038] One end of the water cup 100 in the axial direction is connected to the inner barrel 400 of the dishwasher. In some optional embodiments, the water cup 100 can be installed at the bottom of the inner barrel 400, and the top of the water cup 100 is connected to the bottom of the inner barrel 400 of the dishwasher, and the bottom of the water cup 100 is located outside the inner barrel 400.

[0039] The water diverter valve assembly 200 includes a valve housing 210. In this embodiment, part of the valve housing 210 is composed of part of the water cup 100, that is, part of the valve housing 210 and the water cup 100 are an integrated structure, which realizes the integration of the water diverter valve assembly 200 on the water cup 100, improves the utilization rate of the water cup 100, and is conducive to the miniaturization of the water diverter structure. In this embodiment, part of the valve housing 210 is composed of the part of the water cup 100 located outside the inner barrel 400, so that the valve housing 210 does not occupy the internal space of the inner barrel 400.

[0040] Furthermore, the valve housing 210 is provided with a water inlet 211, a first water outlet 201 and a second water outlet 212. Figure 4As shown, the first water outlet 201 and the second water outlet 212 are respectively located on both sides of the axial direction of the water cup 100, so that the top and bottom of the water cup 100 are provided with water outlets. The water outlet located at the top of the water cup 100 can be connected to the lower spray arm of the dishwasher to supply water to the lower spray arm; the water outlet located at the bottom of the water cup 100 can be connected to the upper spray arm of the dishwasher to supply water to the upper spray arm. In this embodiment, the first water outlet is located at the top of the water cup 100, and the second water outlet 212 is located at the bottom of the water cup 100.

[0041] The water inlet 211 is selectively connected to the first water diversion port 201 or the second water diversion port 212 , so that the water inlet 211 can form a channel with the first water diversion port 201 and the second water diversion port 212 .

[0042] In the water diversion structure provided in this embodiment, the valve housing 210 of the water diversion valve assembly 200 is composed of a part of the water cup 100, realizing the integrated design of the water cup 100 and the water diversion valve assembly 200, the valve housing 210 is provided with a water inlet 211, a first water diversion port 201 and a second water diversion port 212, the water inlet 211 is selectively connected to the first water diversion port 201 or the second water diversion port 212, one of the first water diversion port 201 and the second water diversion port 212 is located on one side of the axial direction of the water cup 100, and the other is located on the other side of the axial direction of the water cup 100, and one end of the axial direction of the water cup 100 is connected to The inner barrel 400 allows one of the first water outlet 201 and the second water outlet 212 to be located outside the inner barrel 400, and the water outlet located outside the inner barrel 400 can be connected to the upper spray arm through a pipeline, so that the water pipe connected to the upper spray arm can be located outside the inner barrel 400, preventing the pipeline from occupying the tableware placement space in the inner barrel 400, thereby improving the space utilization rate of the dishwasher; and the second water outlet 212 is located outside the inner barrel 400, reducing the number of times the pipeline connecting the second water outlet 212 and the upper spray arm needs to be bent, thereby reducing the pressure loss of the pipeline, ensuring the water pressure to the upper spray arm, and thus ensuring the cleaning effect.

[0043] In addition, the second water outlet 212 is directly disposed on the valve housing 210, and there is no need to open an additional hole on the bottom wall of the inner barrel 400, thereby preventing sealing failure and leakage, and ensuring the sealing performance of the dishwasher.

[0044] In some optional embodiments, the second water outlet 212 is located outside the inner barrel 400, and the second water outlet 212 is connected to the upper spray arm through the first pipeline 500. The first pipeline 500 is an integrated structure or a split structure. When the first pipeline 500 is an integrated structure, it can be a hose; when the first pipeline 500 is a split structure, two adjacent pipe sections are arranged at an obtuse angle, and part of the first pipeline 500 can extend along the edges and corners of the inner barrel 400.

[0045] Alternatively, if Figure 2 As shown, the angle between the axial direction of the water inlet 211 and the axial direction of the second water diversion port 212 is a, a>90°, that is, the axial direction of the water inlet 211 and the axial direction of the second water diversion port 212 present a large obtuse angle to reduce the pressure loss caused by factors such as water flow turning and wall collision, so that the pressure of water reaching the upper spray arm can be relatively large, which is conducive to improving the cleaning rate. For example, the angle between the axial direction of the water inlet 211 and the axial direction of the second water diversion port 212 is 120°, 130°, 140°, etc.

[0046] In some optional embodiments, such as Figure 4 As shown, the water diversion structure also includes a driving member 300. The water diversion valve assembly 200 also includes a water diversion disk assembly (not shown) arranged in the valve housing 210. The driving member 300 is transmission-connected to the water diversion disk assembly and is used to drive the water diversion disk assembly to operate. The water diversion disk assembly can adjust the water flow state of the channel formed when the water inlet 211 is connected to the first water diversion port 201, and can adjust the water flow state of the channel formed when the water inlet 211 is connected to the second water diversion port 212. It should be noted that the water flow state includes conduction or closure. When the channel formed when the water inlet 211 is connected to the first water diversion port 201 is in a water flow state of conduction, water can flow to the lower spray arm 700 through the first water diversion port 201; when the channel formed when the water inlet 211 is connected to the second water diversion port 212 is in a water flow state of conduction, water can flow to the upper spray arm through the second water diversion port 212. By providing the driving member 300 and the water distribution plate assembly, the upper spray arm and the lower spray arm 700 can be individually controlled and automatically controlled, the function of the water distribution structure is enriched, and the accuracy of the control of the upper spray arm and the lower spray arm 700 is ensured.

[0047] In this embodiment, the driving member 300 and the water diversion plate assembly are arranged along the axial direction of the water cup 100, so that the driving member 300 and the water diversion plate assembly can be arranged using the space on one side of the axial direction of the water cup 100, thereby making the radial dimension of the water diversion structure smaller, which is conducive to the miniaturization of the water diversion structure and the dishwasher using the water diversion structure.

[0048] Optionally, the water cup 100 includes a cup top 110 and a convex portion (not shown) and a cup body 120, both of which are connected to one side of the cup top 110 in the axial direction. The convex portion and the cup body 120 are arranged radially along the cup top 110, and the convex portion and the cup body 120 are eccentrically arranged relative to the cup top 110. The cup body 120 constitutes part of the valve housing 210, and at least part of the water diversion plate assembly is arranged in the cup body 120. By arranging at least part of the water diversion plate assembly in the convex portion, and arranging the water diversion plate assembly and the driving member 300 in the axial direction of the water cup 100, the driving member 300 and the water diversion plate assembly make full use of the space located on one side of the cup body 120 in the space below the cup top 110, so that the axial dimension of the water diversion structure can also be smaller, which is further conducive to the miniaturization of the water diversion structure and the dishwasher using the water diversion structure.

[0049] Further optionally, if Figure 2 or Figure 5 As shown, the water diversion valve includes a first water diversion tray 220 and a second water diversion tray 230. The first water diversion tray 220 and the second water diversion tray 230 are both provided with water adjustment holes. For the convenience of description, the water adjustment hole on the first water diversion tray 220 is referred to as the first water adjustment hole 221, and the water adjustment hole on the second water diversion tray 230 is referred to as the second water adjustment hole 231. In this embodiment, the first water adjustment hole 221 and the second water adjustment hole 231 can be provided with one or more.

[0050] The driving member 300 can drive the first water diversion plate 220 and the second water diversion plate 230 to rotate synchronously relative to the valve housing 210 to adjust the relative position between the first water diversion port 201 and the water regulating hole and the relative position between the second water diversion port 212 and the water regulating hole, so that the water inlet 211 is selectively connected to the first water diversion port 201 or the second water diversion port 212. By adjusting the relative position between the first water diversion port 201 and the water regulating hole, the water flow state of the channel formed when the water inlet 211, the water regulating hole and the first water diversion port 201 are connected can be adjusted; by adjusting the relative position between the second water diversion port 212 and the water regulating hole, the water flow state of the channel formed when the water inlet 211, the water regulating hole and the second water diversion port 212 are connected can be adjusted.

[0051] By arranging the first water diversion plate 220 and the second water diversion plate 230 to rotate synchronously, the number of driving members 300 required to be arranged is reduced, the water diversion structure is simplified, and the water diversion structure is miniaturized. For example, the driving member 300 is a component capable of outputting torque, such as a motor.

[0052] In this embodiment, Figure 5As shown, the first water distribution tray 220 and the second water distribution tray 230 are arranged opposite to each other in the axial direction of the valve housing 210. It should be noted that the axial direction of the valve housing 210 is the same as the axial direction of the water cup 100. The water inlet 211 is located between the first water distribution tray 220 and the second water distribution tray 230 in the axial direction of the valve housing 210. The water flowing into the valve housing 210 through the water inlet 211 enters the accommodation space formed by the first water distribution tray 220, the second water distribution tray 230 and the side wall of the valve housing 210, so as to facilitate the distribution of water through the first water distribution tray 220 and the second water distribution tray 230.

[0053] Optionally, the first water diversion tray 220 is closer to the water cup 100 than the second water diversion tray 230, and the water inlet 211, the first water regulating hole 221 and the first water diversion outlet 201 can form a first channel. When the first water diversion tray 220 rotates until the orthographic projection of the first water diversion outlet 201 on the first water diversion tray 220 at least partially overlaps with the first water regulating hole 221, the first channel is in a conducting state and can supply water to the lower spray arm 700; when the first water diversion tray 220 rotates until the orthographic projection of the first water diversion outlet 201 on the first water diversion tray 220 is offset from the first water regulating hole 221, the first channel is in a closed state.

[0054] In this embodiment, the water inlet 211, the second water regulating hole 231 and the second water diversion port 212 can form a second channel. When the second water diversion plate 230 rotates to the point where the orthographic projection of the second water diversion port 212 on the second water diversion plate 230 at least partially overlaps with the second water regulating hole 231, the second channel is in a conducting state and can supply water to the upper spray arm; when the second water diversion plate 230 rotates to the point where the orthographic projection of the second water diversion port 212 on the second water diversion plate 230 is offset from the second water regulating hole 231, the second channel is in a closed state.

[0055] Optionally, see Figure 5 or Figure 6 The water diversion valve further includes a transmission assembly 240 and a micro switch 260. The first water diversion plate 220 and the second water diversion plate 230 are connected via the transmission assembly 240. The driving member 300 is in transmission connection with the transmission assembly 240, so that the driving member 300 drives the first water diversion plate 220 and the second water diversion plate 230 by driving the transmission assembly 240 to rotate. The transmission assembly 240 is provided with a convex portion 241 in the circumferential direction. In some optional embodiments, the transmission assembly 240 includes a disc body and a column coaxially connected to the disc body. The first water diversion plate 220 and the second water diversion plate 230 are both connected to the column body, and the convex portion 241 is circumferentially arranged on the disc body.

[0056] In this embodiment, the micro switch 260 is arranged on the valve housing 210, and the contact part of the micro switch 260 is located in the valve housing 210. When the transmission assembly 240 rotates, the convex part 241 can contact the contact part of the micro switch 260 to control the start and stop of the driving member 300. For example, three convex parts 241 are provided, and the three convex parts 241 are evenly and spacedly arranged along the circumference of the disk. The specific structure and working principle of the micro switch 260 can refer to the micro switch 260 structure in the prior art, and this embodiment will not be described in detail here.

[0057] Optionally, the driving member 300 is disposed on the motor cover 310 , and the motor cover 310 is connected to the end of the valve housing 210 away from the water cup 100 , and the micro switch 260 is pressed and fixed by the motor cover 310 and the valve housing 210 to improve the connection reliability of the micro switch 260 .

[0058] When the water-dividing structure is working, the driving member 300 is driven to drive the transmission assembly 240 to rotate, and the transmission assembly 240 drives the first water-dividing plate 220 and the second water-dividing plate 230 to rotate in the same direction. When a convex portion 241 contacts the contact portion of the micro switch 260, the driving member 300 is controlled to start and stop, thereby realizing positioning control of the conduction and closing of the first channel and the second channel, with high control accuracy, so that the first channel and the second channel have a larger flow area, further ensuring the pressure of the water flow at the upper spray arm and the lower spray arm 700.

[0059] As mentioned above, Figure 6 As shown, the water diversion valve further includes an elastic member 250. The elastic member 250 is disposed between the first water diversion tray 220 and the second water diversion tray 230. In some optional embodiments, the elastic member 250 is sleeved on the portion of the transmission assembly 240 located between the first water diversion tray 220 and the second water diversion tray 230, and abuts between the first water diversion tray 220 and the second water diversion tray 230. The elastic member 250 always has a tendency to drive the first water diversion tray 220 and the second water diversion tray 230 away from each other, so that the first water diversion tray 220 and the second water diversion tray 230 are always in contact with each other, thereby improving the sealing performance.

[0060] For example, Figure 5 As shown, one end of the valve housing 210 passes through the cup top 110 and extends to the top of the cup top 110 to form the first water diversion port 201. The first water diversion plate 220 is in contact with the cup top 110, which can prevent the water at the first water diversion port 201 or the first water regulating hole 221 from flowing into the gap between the first water diversion plate 220 and the cup top 110 when the first channel is in a closed state, thereby ensuring the sealing performance of the water diversion structure. For example, the elastic member 250 is a structure with elasticity such as a spring.

[0061] Alternatively, if Figure 5 and Figure 6As shown, the valve housing 210 includes a valve cavity 213 and a valve body 214 which are sealed and connected. The valve cavity 213 is composed of a portion of the water cup 100, specifically, the valve cavity 213 is composed of a convex portion. The water inlet 211 and the first water diversion port 201 are both arranged in the valve cavity 213. The second water diversion port 212 is arranged in the valve body 214. By providing the valve cavity 213 and the valve body 214, it is possible to facilitate the disassembly and assembly of the water diversion valve assembly 200, thereby facilitating the maintenance or replacement of the water diversion valve assembly 200.

[0062] Further optionally, a sealing ring 270 is provided at the connection between the valve cavity 213 and the valve body 214 to achieve a sealed connection between the valve cavity 213 and the valve body 214 .

[0063] In this embodiment, the valve cavity 213 and the valve body 214 are surrounded to form a cavity, the first water diversion plate 220 and the second water diversion plate 230 are arranged in the cavity, and the water inlet 211 is connected to the cavity. The valve body 214 is provided with a flow channel, the second water diversion port 212 is connected to the flow channel, and the second water diversion port 212, the flow channel, the second water regulating hole 231 and the water inlet 211 constitute a second channel.

[0064] It should also be noted that one end of the transmission assembly 240 passes through the valve body 214 and is connected to the first water diversion plate 220 and the second water diversion plate 230, and a shaft seal 320 is arranged between the transmission assembly 240 and the valve body 214, so that the water in the cavity will not seep out through the gap between the transmission assembly 240 and the valve body 214, thereby improving the sealing performance of the water diversion valve assembly 200.

[0065] In this embodiment, the valve cavity 213 is composed of a part of the water cup 100, that is, the water cup 100 and the valve cavity 213 are an integrated structure, so that the valve cavity 213 and the water cup 100 can share some materials. Compared with the form of separate connection, the total thickness of the connection between the valve cavity 213 and the water cup 100 is reduced, thereby reducing the overall volume of the water cup 100 and the valve cavity 213, reducing the installation space required for the water cup 100 and the water diversion valve assembly 200, and meeting the use requirements of the dishwasher with limited bottom space. At the same time, the processing method of the valve cavity 213 and the water cup 100 being integrally formed is reliable, and there is no need to assemble the valve cavity 213 and the water cup 100 in the later stage, which simplifies the assembly process and improves the assembly efficiency of the dishwasher.

[0066] In some optional embodiments, please continue to see Figure 6The valve housing 210 is also provided with a third water diversion port 215. Specifically, the third water diversion port 215 is arranged on the valve body 214. Moreover, the third water diversion port 215 is communicated with the second water diversion port 212. The third water diversion port 215 is communicated with the second water diversion port 212 through the internal structure of the valve body 214. For example, the third water diversion port 215 is communicated with the second water diversion port 212 through the flow channel, so that the third water diversion port 215, the flow channel, the second water regulating hole 231 and the water inlet 211 can form a third channel. The state of the third channel is the same as that of the second channel, that is, both are in the on state or the off state at the same time. The third water diversion port 215 is configured to be communicated with the small spray arm 800 of the dishwasher. By setting the third water diversion port 215 outside the inner barrel 400, the second pipeline 600 used to connect the third water diversion port 215 and the small spray arm 800 is located outside the inner barrel 400, which further reduces the space occupied by the inner barrel 400, increases the placement space of the inner barrel 400, and improves the space utilization rate of the dishwasher.

[0067] In this embodiment, the side wall of the inner barrel 400 is provided with an upper spray arm water inlet joint, and the first pipe 500 is sealed and connected to the upper spray arm water inlet joint to prevent water leakage; similarly, the bottom wall of the inner barrel 400 is provided with a small spray arm water inlet joint, and the second pipe 600 is sealed and connected to the small spray arm water inlet joint to prevent water leakage.

[0068] This embodiment further provides a dishwasher, comprising an inner barrel 400 and the above-mentioned water separation structure, wherein one end of the water cup 100 in the axial direction is connected to the inner barrel 400. The dishwasher provided in this embodiment has a high space utilization rate and a good cleaning effect.

[0069] Optionally, the top of the water cup 100 is connected to the bottom of the inner barrel 400 .
