[0073] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0075] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0077] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0078] The first aspect of this application discloses a flow divider valve 100, combined with... Figures 1 to 7 As shown, in some embodiments, the diversion valve 100 includes a valve housing 1000 and a valve core 2000. The valve housing 1000 is provided with an inlet 1100, an outlet 1300, and an outlet 1400. The valve core 2000 is installed inside the valve housing 1000 and includes a fixed valve core 2100 and a movable valve core 2200. The fixed valve core 2100 is provided with a flow passage 2130. The outlet 2132 of the flow passage 2130 communicates with the outlet 1400. The movable valve core 2200 is adapted to be connected to the drive mechanism 700 so as to be rotatable relative to the fixed valve core 2100. The movable valve core 2200 is adapted to open and close the outlet 1300 when rotating, and is also adapted to open and close the inlet 2131 of the flow passage 2130 when rotating.

[0079] The valve housing 1000 is hollow inside, and the valve core 2000 is installed inside the valve housing 1000 and thus supported by the valve housing 1000. The valve housing 1000 can be a one-piece molded structure or a split component connected and fixed by a connecting means. The valve housing 1000 can be a separate component or molded together with other components; this embodiment is not limited. The valve housing 1000 is provided with an inlet 1100, an outlet 1300, and an outlet 1400. The inlet 1100, outlet 1300, and outlet 1400 are respectively connected to the interior of the valve housing 1000. When the valve core 2000 is installed inside the valve housing 1000, the inlet 1100, outlet 1300, and outlet 1400 can cooperate with the valve core 2000.

[0080] The valve core 2000 includes a fixed valve core 2100 and a movable valve core 2200. The fixed valve core 2100 is fixed relative to the valve housing 1000 when the valve core 2000 is installed inside the valve housing 1000. The movable valve core 2200 is movable relative to both the valve housing 1000 and the fixed valve core 2100 when the valve core 2000 is installed inside the valve housing 1000. For example, when the fixed valve core 2100 is installed inside the valve housing 1000, it is fixedly connected to the valve housing 1000 by screws, while the movable valve core 2200 is rotatable relative to both the fixed valve core 2100 and the valve housing 1000.

[0081] The movable valve core 2200 is used to connect with the drive mechanism 700, which is a component for outputting mechanical energy. The movable valve core 2200 and the drive mechanism 700 can be directly or indirectly connected. Driven by the drive mechanism 700, the movable valve core 2200 can rotate inside the valve housing 1000. Through the rotation of the movable valve core 2200, the drain port 1300 can be opened and closed. The opening and closing of the drain port 1300 when the movable valve core 2200 rotates means that the movable valve core 2200 has... The valve core 2200 has the function of opening the drain port 1300 when rotating, and also has the function of closing the drain port 1300 (as described in other parts of this document regarding opening and closing). When the movable valve core 2200 opens the drain port 1300, fluid can enter the interior of the valve body 1000 from the inlet port 1100 and be discharged through the drain port 1300 to the target object. When the movable valve core 2200 closes the drain port 1300, fluid can enter the interior of the valve body 1000 from the inlet port 1100 but cannot be discharged through the drain port 1300.

[0082] Since the movable valve core 2200 is rotatable and needs to open and close the drain port 1300, the drain port 1300 needs to be located in the circumferential direction of the movable valve core 2200's rotation. That is, the drain port 1300 needs to be located in the valve housing 1000 and in the circumferential direction of the movable valve core 2200's rotation. This restricts the arrangement of the drain port 1300, and the drain port 1300 cannot be arranged in other positions of the valve housing 1000. This also affects the arrangement of the target object. The same applies to related technologies, which include the valve housing and the valve core rotatably disposed in the valve housing. The outlet on the valve housing needs to be set in the circumferential direction of the valve core's rotation.

[0083] Therefore, in this embodiment, the valve core 2000 also includes a fixed valve core 2100 that cooperates with the movable valve core 2200. The fixed valve core 2100 is provided with a flow channel 2130. The outlet 2132 of the flow channel 2130 is connected to the outlet 1400. By rotating the movable valve core 2200, the movable valve core 2200 can open and close the inlet 2131 of the flow channel 2130. The movable valve core 2200 opening and closing the inlet 2131 of the flow channel 2130 when rotating means that the movable valve core 2200 has the function of opening the inlet 2131 of the flow channel 2130 when rotating, and also has the function of closing the inlet 2131 of the flow channel 2130. When the movable valve core 2200 opens the inlet 2131 of the flow passage 2130, fluid can enter the interior of the valve body 1000 from the inlet 1100 and flow through the flow passage 2130 to the outlet 1400, ultimately reaching the target object from the outlet 1400. When the movable valve core 2200 closes the inlet 2131 of the flow passage 2130, fluid can enter the interior of the valve body 1000 from the inlet 1100 but cannot enter the flow passage 2130. Through the arrangement of the flow passage 2130, the outlet 1400 can be located at multiple positions on the valve body 1000, not limited to the circumferential direction of the valve core 2000's rotation, reducing restrictions on structural layout.

[0084] In some embodiments, continue to combine Figures 1 to 7 As shown, the fixed valve core 2100 and the valve housing 1000 define a flow divider chamber 1200. The movable valve core 2200 is disposed in the flow divider chamber 1200. The inlet 1100 is connected to the flow divider chamber 1200. The flow divider chamber 1200 is adapted to be connected to the outlet 1300 when the movable valve core 2200 opens the outlet 1300. The flow divider chamber 1200 is also adapted to be connected to the outlet 1400 when the movable valve core 2200 opens the inlet 2131 of the flow passage 2130.

[0085] The valve core 2000 and the valve housing 1000 can be assembled in the following manner: the valve housing 1000 is provided with an installation port 1500 that communicates with its interior; the valve core 2000 is inserted into the interior of the valve housing 1000 through the installation port 1500; when the valve core 2000 is installed in place, the valve core 2100 and the valve housing 1000 are fixed to define the flow divider chamber 1200.

[0086] The design of the flow divider 1200 and the placement of the movable valve core 2200 within it facilitates fluid flow control. When fluid needs to be discharged through the drain port 1300, the movable valve core 2200 rotates to open the drain port 1300, allowing fluid to enter the flow divider 1200 from the inlet 1100 and exit through the drain port 1300. When fluid does not need to be discharged through the drain port 1300, the movable valve core 2200 rotates to close the drain port 1300, allowing fluid to enter the flow divider 1200 from the inlet 1100 but not exit through the drain port 1300. When fluid needs to be discharged through the outlet port 1400, the movable valve core 2200 rotates to open the inlet 2131 of the flow passage 2130, allowing fluid to enter the flow divider 1200 from the inlet 1100, flow through the flow passage 2130 from the flow divider 1200, and exit through the outlet port 1400. When fluid does not need to be discharged through outlet 1400, the movable valve core 2200 rotates to close the inlet 2131 of the flow passage 2130, and the fluid enters the diversion chamber 1200 from inlet 1100 but cannot enter the flow passage 2130.

[0087] In some embodiments, combined with Figure 5 , Figure 6 as well as Figures 13 to 18 As shown, the fixed valve core 2100 is provided with a shaft hole 2140, and the diverter valve 100 also includes a drive shaft 3000. The drive shaft 3000 passes through the shaft hole 2140, and one end of the drive shaft 3000 is connected to the movable valve core 2200. The other end of the drive shaft 3000 is adapted to be connected to the drive mechanism 700.

[0088] Since the valve housing 1000 and the fixed valve core 2100 define the flow divider chamber 1200, and the movable valve core 2200 is disposed in the flow divider chamber 1200, and the movable valve core 2200 needs to be connected to the drive mechanism 700, in this embodiment, the fixed valve core 2100 is provided with a shaft hole 2140. The flow divider valve 100 is adapted to be connected to the drive mechanism 700 via a drive shaft 3000, which passes through the shaft hole 2140. This arrangement enables the drive of the movable valve core 2200. Given that the fixed valve core 2100 is provided with a shaft hole 2140, the flow passage 2130 can be disposed around the shaft hole 2140. Furthermore, since the drive shaft 3000 passes through the shaft hole 2140 and is connected to the movable valve core 2200, a sealing ring can be provided between the drive shaft 3000 and the hole wall of the shaft hole 2140 to prevent fluid leakage through the shaft hole 2140.

[0089] In some embodiments, combined with Figure 5 and Figure 6As shown, the drive shaft 3000 is rotatably configured, and the movable valve core 2200 and the fixed valve core 2100 are arranged sequentially along the rotation axis of the drive shaft 3000. By arranging the movable valve core 2200 and the fixed valve core 2100 sequentially along the rotation axis of the drive shaft 3000, the structure of the valve core 2000 is more compact. Optionally, the rotation axis of the movable valve core 2200 and the rotation axis of the drive shaft 3000 can be coaxially configured.

[0090] In some embodiments, one end of the drive shaft 3000 is plugged into the movable valve core 2200 to facilitate the assembly of the drive shaft 3000 and the movable valve core 2200. For example, one end of the drive shaft 3000 and the movable valve core 2200 are connected by a spline, so that the rotation of the drive shaft 3000 can drive the movable valve core 2200 to rotate. Furthermore, the end of the movable valve core 2200 facing away from the drive shaft 3000 can abut against the end wall of the valve housing 1000, thus axially limiting the movable valve core 2200 and preventing it from detaching from the drive shaft 3000.

[0091] In some embodiments, combined with Figures 5 to 7 As shown, the valve housing 1000 is provided with a horizontally open mounting port 1500, which can be understood as the horizontal direction. The valve core 2000 is adapted to be inserted into the interior of the valve housing 1000 through the mounting port 1500. The rotation axis of the drive shaft 3000 is arranged horizontally, so that the drain port 1300 and the outlet port 1400 are more suitable for the arrangement of the dishwasher's spray arms.

[0092] In some embodiments, combined with Figure 5 as well as Figures 13 to 17 As shown, a first sealing ring 2151 and a second sealing ring 2152 are provided between the fixed valve core 2100 and the valve body 1000, and the outlet 2132 of the flow passage 2130 is located between the first sealing ring 2151 and the second sealing ring 2152. The first sealing ring 2151 prevents fluid from flowing from the gap between the fixed valve core 2100 and the valve body 1000 to the outlet 1400, and the second sealing ring 2152 prevents fluid flowing from the flow passage 2130 to the outlet 1400 from leaking from the gap between the fixed valve core 2100 and the valve body 1000 to the outside of the diverter valve 100.

[0093] For example, the valve housing 1000 is provided with an installation port 1500 communicating with its interior. The valve core 2000 is inserted into the interior of the valve housing 1000 through the installation port 1500. When the valve core 2000 is installed in place, the fixed valve core 2100 and the valve housing 1000 define a flow divider chamber 1200. The movable valve core 2200 is located in the flow divider chamber 1200. A first sealing ring 2151 and a second sealing ring 2152 are provided between the fixed valve core 2100 and the valve housing 1000. That is, the inner sides of the first sealing ring 2151 and the second sealing ring 2152 abut against the fixed valve core 2100, and the outer sides abut against the valve housing 1000. Along the axial direction of the fixed valve core 2100, the first sealing ring 2151 and the second sealing ring 2152 abut against the fixed valve core 2100. The second sealing rings 2152 are arranged alternately, and the first sealing ring 2151 is closer to the movable valve core 2200 relative to the second sealing rings 2152. The outlet 2132 of the flow passage 2130 is located between the first sealing ring 2151 and the second sealing ring 2152, that is, the outlet 1400 is located between the first sealing ring 2151 and the second sealing ring 2152. In this way, the fluid in the diversion chamber 1200 cannot flow to the outlet 1400 through the gap between the fixed valve core 2100 and the valve shell 1000, and the fluid discharged from the outlet 2132 of the flow passage 2130 cannot leak to the outside of the diversion valve 100 through the gap between the fixed valve core 2100 and the valve shell 1000.

[0094] In some embodiments, combined with Figures 5 to 11 As shown, the movable valve core 2200 includes a support portion 2220 and a blocking portion 2210. The movable valve core 2200 is adapted to be connected to the drive mechanism 700 through the support portion 2220. The support portion 2220 is adapted to open and close the inlet 2131 of the flow passage 2130 when the movable valve core 2200 rotates. The blocking portion 2210 is adapted to open and close the drain port 1300 when the movable valve core 2200 rotates.

[0095] When the movable valve core 2200 rotates, the support part 2220 and the shielding part 2210 rotate synchronously. Based on the rotatable setting of the movable valve core 2200, the support part 2220 is provided to facilitate the opening and closing of the inlet 2131 of the flow passage 2130. For example, the support part 2220 is provided with a flow port 2221. The flow port 2221 is suitable for opening the inlet 2131 of the flow passage 2130 when it is opposite to the inlet 2131 of the flow passage 2130, and is suitable for closing the inlet 2131 of the flow passage 2130 when it is offset from the inlet 2131 of the flow passage 2130. By providing the shielding part 2210, it is convenient to open and close the drain port 1300. For example, the movable valve core 2200 opens the drain port 1300 when it rotates to the point where the shielding part 2210 and the drain port 1300 are misaligned, and closes the drain port 1300 when it rotates to the point where the shielding part 2210 and the drain port 1300 are opposite each other.

[0096] Since the drain port 1300 is located in the circumferential direction of the rotating movable valve core 2200, the shielding part 2210 can extend along the circumferential direction of the movable valve core 2200, thus facilitating the cooperation between the shielding part 2210 and the drain port 1300. The fixed valve core 2100 is fixed inside the valve housing 1000. Since the support part 2220 needs to be connected to the drive mechanism 700, the support part 2220 can be positioned at one end of the movable valve core 2200 adjacent to the axial direction of the fixed valve core 1000, facilitating its cooperation with the inlet 2131 of the flow channel 2130. For example, the shielding part 2210 and the support part 2220 can be configured to be perpendicular to each other. To reduce the manufacturing difficulty of the movable valve core 2200, the shielding part 2210 and the support part 2220 are assembled together by a snap-fit ​​connection.

[0097] In some embodiments, combined with Figures 13 to 17 As shown, the fixed valve core 2100 includes a first housing portion 2110 and a second housing portion 2120. The first housing portion 2110 and the second housing portion 2120 are connected to enclose a flow passage 2130. In this way, the shape of the flow passage 2130 can be designed according to actual needs. Especially when the flow passage 2130 extends in a tortuous manner, the connection between the first housing portion 2110 and the second housing portion 2120 makes it easier to form the flow passage 2130.

[0098] Optionally, the first housing portion 2110 is provided with an inlet 2131 of a flow channel 2130, the inlet 2131 of which is located on the end face of the first housing portion 2110. The support portion 2220 is rotatably mounted on the first housing portion 2110 to open and close the inlet 2131 of the flow channel 2130. The inlet 2131 of the flow channel 2130 is located on the end face of the first housing portion 2110, facilitating its engagement with the movable valve core 2200.

[0099] The first shell portion 2110 has an outlet 2132 of a flow channel 2130 on its circumferential sidewall. The outlet 1400 is located in the circumferential direction of the first shell portion 2110. The second shell portion 2120 has a groove 2121. The first shell portion 2110 is covered by the enclosing groove 2121 to form a flow channel 2130. That is, at this time, the inlet 2131 of the flow channel 2130 is connected to the groove 2121, and the outlet 2132 of the flow channel 2130 is connected to the groove 2121. The outlet 2132 of the flow channel 2130 is located on the circumferential sidewall of the first shell portion 2110, which is convenient for cooperation with the spray arm of the dishwasher. Alternatively, the circumferential sidewall of the second shell 2120 may be provided with an outlet 2132 of the overflow channel 2130, the outlet 1400 being located in the circumferential direction of the second shell 2110, the second shell 2120 being provided with a groove 2121, and the first shell 2110 being covered by an enclosing groove 2121 to form an overflow channel 2130.

[0100] In some embodiments, combined with Figures 13 to 17 As shown, the second shell portion 2120 is provided with at least two grooves 2121 that extend and are alternately arranged along the circumference of the second shell portion 2120. In this way, in conjunction with the first shell portion 2110, at least two flow channels 2130 (corresponding to the first flow channel 2133 and the second flow channel 2134 in the following text) can be formed in a limited space, and the structure is more compact.

[0101] In some embodiments, combined with Figures 1 to 18 As shown, the diversion valve 100 includes at least two drain ports 1300, namely a first drain port 1310 and a second drain port 1320, that is, one of the two drain ports 1300 is defined as the first drain port 1310 and the other is defined as the second drain port 1320; the diversion valve 100 includes a first outlet port 1410, that is, one of the outlet ports 1400 is defined as the first outlet port 1410; the fixed valve core 2100 includes a first flow passage 2133, that is, one of the flow passages 2130 is defined as the first flow passage 2133, and the outlet 2132 of the first flow passage 2133 is connected to the first outlet port 1410; the movable valve core 2200 is adapted to open at least one of the first drain port 1310, the second drain port 1320 and the inlet 2131 of the first flow passage 2133 when rotating.

[0102] The first drain port 1310, the second drain port 1320, and the first outlet port 1410 correspond to three target objects. The movable valve core 2200 opens at least one of the first drain port 1310, the second drain port 1320, and the inlet 2131 of the first flow passage 2133, which means closing the remaining parts of the first drain port 1310, the second drain port 1320, and the inlet 2131 of the first flow passage 2133. This allows the diversion valve 100 to have multiple diversion states. By rotating the movable valve core 2200, the fluid is directed to the corresponding target object, satisfying multiple diversion requirements.

[0103] For example, combining Figure 19 As shown, the valve core 2000 can be rotated to the first position. When the valve core 2000 is rotated to the first position, the valve core 2000 closes the first drain port 1310 and the second drain port 1320, and opens the inlet 2131 of the first flow passage 2133. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged from the first outlet port 1410 through the first flow passage 2133.

[0104] Combination Figure 20As shown, the valve core 2000 can be rotated to the second position. When the valve core 2000 is rotated to the second position, the valve core 2000 closes the first drain port 1310 and the inlet 2131 of the first flow passage 2133, and opens the second drain port 1320. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the second drain port 1320.

[0105] Combination Figure 21 As shown, the valve core 2000 can be rotated to the third position. When the valve core 2000 is rotated to the third position, the valve core 2000 closes the second drain port 1320 and the inlet 2131 of the first flow passage 2133, and opens the first drain port 1310. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the first drain port 1310.

[0106] Combination Figure 22 As shown, the valve core 2000 can be rotated to the fourth position. When the valve core 2000 is rotated to the fourth position, the valve core 2000 closes the second drain port 1320 and opens the first drain port 1310 and the inlet 2131 of the first flow passage 2133. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the first drain port 1310 and the first outlet port 1410.

[0107] Specifically, in some embodiments, the movable valve core 2200 includes a support portion 2220 and a blocking portion 2210. The movable valve core 2200 is adapted to be connected to the drive mechanism 700 through the support portion 2220. The support portion 2220 is provided with a flow port 2221. The flow port 2221 is adapted to open the inlet 2131 of the flow channel 2130 when it is opposite to the inlet 2131 of the flow channel 2130, and is adapted to close the inlet 2131 of the flow channel 2130 when it is misaligned with the inlet 2131 of the flow channel 2130. The blocking portion 2210 is adapted to close the drain port 1300 when it is opposite to the drain port 1300, and is adapted to open the drain port 1300 when it is misaligned with the drain port 1300.

[0108] The movable valve core 2200 includes two blocking portions 2210 arranged alternately along its circumferential direction, namely a first blocking portion 2211 and a second blocking portion 2212, that is, one of the two blocking portions 2210 is defined as the first blocking portion 2211 and the other is defined as the second blocking portion 2212; the first blocking portion 2211 has a circumferential arc length along the movable valve core 2200 that is greater than the circumferential arc length of the second blocking portion 2212 along the movable valve core 2200; the first blocking portion 2211 is adapted to open and close at least one of the first drain port 1310 and the second drain port 1320; the second blocking portion 2212 is adapted to open and close the first drain port 1310, or the second blocking portion 2212 is adapted to open and close the second drain port 1420.

[0109] The support part 2220 is provided with a first flow port 2222, that is, one of the flow ports 2221 is defined as the first flow port 2222. The flow diversion valve 100 can achieve multiple flow diversion modes through the cooperation of the first blocking part 2211, the second blocking part 2212 and the first flow port 2222.

[0110] In some embodiments of this application, combined with Figure 1 As shown, the diverter valve 100 also includes a second outlet 1420, the fixed valve core 2100 also includes a second flow passage 2134, the outlet 2132 of the second flow passage 2134 is connected to the second outlet 1420, and the movable valve core 2200 is also adapted to open and close the inlet 2131 of the second flow passage 2134 when rotating.

[0111] The diverter valve 100 includes at least two outlets 1400, namely a first outlet 1410 and a second outlet 1420, where one of the two outlets 1400 is defined as the first outlet 1410 and the other as the second outlet 1420; the fixed valve core 2100 includes at least two flow channels 2130, namely a first flow channel 2133 and a second flow channel 2134, where one of the two flow channels 2130 is defined as the first flow channel 2133 and the other as the second flow channel 2134. The outlet 2132 of the first outlet 1410 is connected to the outlet 2132 of the second flow passage 2134 and the outlet 2132 of the second flow passage 2134 are connected to the outlet 1420; the movable valve core 2200 is adapted to open at least one of the first outlet 1310, the second outlet 1320, the inlet 2131 of the first flow passage 2133 and the inlet 2131 of the second flow passage 2134 when rotating, and to close the remaining portions of the first outlet 1310, the second outlet 1320, the inlet 2131 of the first flow passage 2133 and the inlet 2131 of the second flow passage 2134.

[0112] For example, combining Figure 19 As shown, the valve core 2000 can be rotated to the first position. When the valve core 2000 is rotated to the first position, the valve core 2000 closes the first drain port 1310, the second drain port 1320, and the inlet 2131 of the second flow passage 2134, and opens the inlet 2131 of the first flow passage 2133. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged from the first outlet port 1410 through the first flow passage 2133.

[0113] Combination Figure 20As shown, the valve core 2000 can be rotated to the second position. When the valve core 2000 is rotated to the second position, the valve core 2000 closes the first drain port 1310, the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134, and opens the second drain port 1320. Fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the second drain port 1320.

[0114] Combination Figure 21 As shown, the valve core 2000 can be rotated to the third position. When the valve core 2000 is rotated to the third position, the valve core 2000 closes the second drain port 1320, the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134, and opens the first drain port 1310. Fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the first drain port 1310.

[0115] Combination Figure 22 As shown, the valve core 2000 can be rotated to the fourth position. When the valve core 2000 is rotated to the fourth position, the valve core 2000 closes the second drain port 1320 and the inlet 2131 of the second flow passage 2134, and opens the first drain port 1310 and the inlet 2131 of the first flow passage 2133. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the first drain port 1310 and the first outlet port 1410.

[0116] Combination Figure 23 As shown, the valve core 2000 can be rotated to the fifth position. When the valve core 2000 is rotated to the fifth position, the valve core 2000 closes the first drain port 1310 and the inlet 2131 of the first flow passage 2133, and opens the second drain port 1320 and the inlet 2131 of the second flow passage 2134. The fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the second drain port 1320 and the second outlet port 1420.

[0117] Combination Figure 24 As shown, the valve core 2000 can be rotated to the sixth position. When the valve core 2000 is rotated to the sixth position, the valve core 2000 closes the inlet 2131 of the first flow passage 2133 and the inlet 2131 of the second flow passage 2134, and opens the first drain port 1310 and the second drain port 1320. Fluid enters the diversion chamber 1200 from the inlet port 1100 and can be discharged through the first drain port 1310 and the second drain port 1320.

[0118] Combination Figure 25As shown, the valve core 2000 can be rotated to the seventh position. When the valve core 2000 is rotated to the seventh position, the valve core 2000 closes the inlet 2131 of the first flow passage 2133 and opens the inlet 2131 of the second flow passage 2134, the first drain port 1310 and the second drain port 1320. The fluid enters the diversion chamber 1200 from the inlet 1100 and can be discharged through the first drain port 1310, the second drain port 1320 and the second outlet port 1420.

[0119] Optionally, having the first drain port 1310 and the second drain port 1320 located in the circumferential direction of the movable valve core 2200 is more conducive to achieving the above-mentioned mode and helps to simplify the structure. Similarly, the first outlet port 1410 and the second outlet port 1420 are located in the circumferential direction of the fixed valve core 2100. In addition, the drain ports 1300 (first drain port 1310, second drain port 1320) and outlet ports 1400 (first outlet port 1410, second outlet port 1420) are arranged along the extension direction of the rotation axis of the movable valve core 2200, which facilitates cooperation with the spray arm.

[0120] When the movable valve core 2200 includes a first blocking part 2211 and a second blocking part 2212, and the support part 2220 is provided with a first flow port 2222 and a second flow port 2223:

[0121] Combination Figure 19 As shown, when the valve core 2000 rotates to the first position, the first blocking part 2211 is opposite to the first drain port 1310 and the second drain port 1320, the second blocking part 2212 is offset from the first drain port 1310 and the second drain port 1320, the first flow port 2222 is opposite to the inlet 2131 of the first flow channel 2133 and offset from the inlet 2131 of the second flow channel 2134, and the second flow port 2223 is offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134. Thus, the first drain port 1310, the second drain port 1320 and the inlet 2131 of the second flow channel 2134 are closed and the inlet 2131 of the first flow channel 2133 is opened.

[0122] Combination Figure 20 As shown, when the valve core 2000 rotates to the second position, the first blocking part 2211 is offset from the first drain port 1310 and the second drain port 1320, the second blocking part 2212 is opposite to the first drain port 1310 and offset from the second drain port 1320, and the first flow port 2222 and the second flow port 2223 are both offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134. In this way, the first drain port 1310, the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134 are closed and the second drain port 1320 is opened.

[0123] Combination Figure 21 As shown, when the valve core 2000 rotates to the third position, the first blocking part 2211 is offset from the first drain port 1310 and the second drain port 1320, the second blocking part 2212 is offset from the first drain port 1310 and is opposite to the second drain port 1320, and the first flow port 2222 and the second flow port 2223 are both offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134. In this way, the second drain port 1320, the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134 are closed and the first drain port 1310 is opened.

[0124] Combination Figure 22 As shown, when the valve core 2000 rotates to the fourth position, the first blocking part 2211 is offset from the first drain port 1310 and faces the second drain port 1320. The second blocking part 2212 is offset from the first drain port 1310 and the second drain port 1320. The first flow port 2222 is offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134. The second flow port 2223 faces the inlet 2131 of the first flow channel 2133 and is offset from the inlet 2131 of the second flow channel 2134. Thus, the second drain port 1320 and the inlet 2131 of the second flow channel 2134 are closed, and the first drain port 1310 and the inlet 2131 of the first flow channel 2133 are opened.

[0125] Combination Figure 23 As shown, when the valve core 2000 rotates to the fifth position, the first blocking part 2211 is opposite to the first drain port 1310 and offset from the second drain port 1320, the second blocking part 2212 is offset from the first drain port 1310 and the second drain port 1320, the first flow port 2222 is offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134, the second flow port 2223 is offset from the inlet 2131 of the first flow channel 2133 and opposite to the inlet 2131 of the second flow channel 2134, thus closing the first drain port 1310 and the inlet 2131 of the first flow channel 2133 and opening the second drain port 1320 and the inlet 2131 of the second flow channel 2134.

[0126] Combination Figure 24As shown, when the valve core 2000 is adapted to rotate to the sixth position, the first blocking part 2211 and the second blocking part 2212 are both offset from the first drain port 1310 and the second drain port 1320, and the first flow port 2222 and the second flow port 2223 are both offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134. In this way, the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134 are closed, and the first drain port 1310 and the second drain port 1320 are opened.

[0127] Combination Figure 25 As shown, when the valve core 2000 is adapted to rotate to the seventh position, the first blocking part 2211 and the second blocking part 2212 are both offset from the first drain port 1310 and the second drain port 1320. The first flow port 2222 and the inlet 2131 of the first flow channel 2133 are offset and opposite to the inlet 2131 of the second flow channel 2134. The second flow port 2223 is offset from the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134. Thus, the inlet 2131 of the first flow channel 2133 is closed and the inlet 2131 of the second flow channel 2134, the first drain port 1310 and the second drain port 1320 are opened.

[0128] To facilitate the coordination between the first shielding part 2211, the second shielding part 2212, the first drain port 1310, and the second drain port 1320 to form the aforementioned various diversion modes, combined with Figure 8 and Figure 12As shown, in some embodiments, along the circumferential direction of the movable valve core 2200, the arc length of the first blocking portion 2211 is L1, the arc length of the second blocking portion 2212 is L2, the arc length between the sides of the first blocking portion 2211 and the second blocking portion 2212 that are close to each other is L3, the arc length between the other sides of the first blocking portion 2211 and the second blocking portion 2212 that are close to each other is L4, the arc length of the first drain port 1310 is L5, the arc length of the second drain port 1320 is L6, and the arc length between the sides of the first drain port 1310 and the second drain port 1320 that are far away from each other is L7, satisfying L1 > L7, L2 > L5, L2 > L6, L3 > L5, L3 > L6, L4 > L5, L4 > L6, and L3 < L4. It is understandable that the positions of the first flow port 2222 and the second flow port 2223 relative to the first shielding part 2211 and the second shielding part 2212 remain unchanged, and the inlet 2131 of the first flow channel 2133 and the inlet 2131 of the second flow channel 2134 are fixed relative to the housing. Once the positional relationship between the first shielding part 2211, the second shielding part 2212, the first drain port 1310 and the second drain port 1320 is determined, the positional relationship between the first flow port 2222 and the second flow port 2223 on the support part 2220 is also determined based on the fact that the diversion valve 100 can realize the aforementioned diversion modes.

[0129] The second aspect of this application discloses a dishwasher, combined with Figures 1 to 25 As shown, the dishwasher includes the aforementioned diversion valve 100. The inlet 1100 of the diversion valve 100 is adapted to receive water flow and / or airflow. When water flow is received at the inlet 1100, the diversion valve 100 diverts the water flow to deliver it to the target object for cleaning. When airflow is received at the inlet 1100, the diversion valve 100 diverts the airflow to deliver it to the target object for drying. It is understood that the diversion valve 100 of the dishwasher in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0130] In some embodiments, the dishwasher includes a water cup 200, an upper spray arm, a middle spray arm, and a lower spray arm. The water cup 200, upper spray arm, middle spray arm, and lower spray arm respectively constitute the target objects mentioned above. When the diversion valve 100 includes a first drain port 1310, a second drain port 1320, a first outlet port 1410, and a second outlet port 1420, the first drain port 1310 is connected to the lower spray arm, the second drain port 1320 is connected to the middle spray arm, the first outlet port 1410 is connected to the water cup 200, and the second outlet port 1420 is connected to the upper spray arm. In some embodiments, the valve housing 1000 can be directly formed on the water cup 200, reducing the number of parts and making it easier to cooperate with the water cup 200, upper spray arm, middle spray arm, and lower spray arm. Optionally, the valve housing 1000 and the water cup 200 are integrally formed, which can reduce the number of parts and improve integration.

[0131] In other words, when valve core 2000 rotates to the first position, fluid flows to water cup 200. When valve core 2000 rotates to the second position, fluid flows to the middle spray arm. When valve core 2000 rotates to the third position, fluid flows to the lower spray arm. When valve core 2000 rotates to the fourth position, fluid flows to both the lower spray arm and water cup 200. When valve core 2000 rotates to the fifth position, fluid flows to both the middle spray arm and upper spray arm. When valve core 2000 rotates to the sixth position, fluid flows to both the lower spray arm and middle spray arm. When valve core 2000 rotates to the seventh position, fluid flows to the lower spray arm, middle spray arm, and upper spray arm.

[0132] When the fluid is water, the water can be sprayed from the corresponding upper spray arm, middle spray arm and lower spray arm to rinse the tableware, and can be sprayed onto the water cup 200 to rinse the filter screen of the water cup 200. When the fluid is air, the air can be sprayed from the corresponding upper spray arm, middle spray arm and lower spray arm to dry the pipeline, and can be sprayed onto the water cup 200 to dry the water cup 200.

[0133] The diversion valve 100 can receive water flow and / or air flow through the following scheme, combined with Figure 1 and Figure 2As shown, the dishwasher includes a washing pump 500, an air supply device 600, and a switching device 400. The switching device 400 is connected to the water cup 200. The inlet of the washing pump 500 is connected to the switching device 400. The outlet of the washing pump 500 is connected to the inlet 1100. The outlet of the air supply device 600 is connected to the switching device 400. When water flow is required, the switching device 400 switches to the corresponding flow path, connecting the water cup 200 and the washing pump 500, and isolating it from the air supply device 600. The washing pump 500 operates, and water flows from the water cup 200 through the switching device 400 and is then drawn into the washing pump 500. The washing pump 500 pumps the water flow towards the inlet 1100, and then the flow is diverted by the diversion valve 100 to direct the water flow to the corresponding target objects (upper spray arm, middle spray arm, lower spray arm, water cup 200). When air flow is required, the switching device 400 switches to another flow path to connect the air supply device 600 and the washing pump 500. The airflow provided by the air supply device 600 flows through the switching device 400 and continues to flow through the washing pump 500, entering the diversion chamber 1200 through the inlet 1100. Then, the airflow is diverted by the diversion valve 100 to direct the airflow to the corresponding target objects (upper spray arm, middle spray arm, lower spray arm, water cup 200).
