DETAILED DESCRIPTION

[0039] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The utility model provides a water diversion valve assembly and a dishwasher. A plurality of embodiments are given below to describe the water diversion valve assembly and the dishwasher provided by the utility model in detail.

[0041] Example 1

[0042] The water diversion valve assembly provided in this embodiment is as follows: Figures 1 to 15 As shown, it includes a water diversion groove 307 and a water diversion member 6; the side wall of the water diversion groove 307 is provided with a first water outlet 306, and the bottom wall of the water diversion groove 307 is provided with a second water outlet 302 and a third water outlet; the water diversion member 6 is arranged in the water diversion groove 307, and the water diversion member 6 can block the second water outlet 302 and the third water outlet; the water diversion member 6 is provided with a through hole, and the water diversion member 6 can rotate around the axis of the water diversion groove 307 to drive the through hole to connect with any one of the second water outlet 302 and the third water outlet; the side of the water diversion member 6 is provided with a water blocking structure 601, and the water blocking structure 601 can block the first water outlet 306; when the through hole is connected with the second water outlet 302, the first water outlet 306 is in an open state; when the through hole is connected with the third water outlet, the water blocking structure 601 blocks the first water outlet 306.

[0043] When the water diverter 6 rotates to the position where the through hole is connected to the second water port 302, the water blocking structure 601 does not block the first water port 306, the first water port 306 is in an open state, and the first water port 306 and the second water port 302 can cooperate to connect to achieve a waterway switching; when the water diverter 6 rotates to the position where the through hole is connected to the third water port, the water blocking structure 601 blocks the first water port 306, the first water port 306 is in a closed state, and the third water port can achieve another waterway switching. The water diverter valve assembly provided in this embodiment, because the first water port 306 is set on the side wall of the water diverter tank 307, the first water port 306 does not occupy the bottom wall space of the water diverter tank 307, and more waterway control can be achieved in the same space of the water diverter valve assembly.

[0044] In an optional embodiment, the first water outlet 306 is used to communicate with an external water source, the second water outlet 302 is used to communicate with the inlet of the water collecting tank 3 of the water diversion valve assembly, and the third water outlet is used to communicate with the water channel inlet of the water collecting tank 3 of the water diversion valve assembly.

[0045] When the water diversion member 6 rotates, the water blocking structure 601 will also rotate accordingly. When the water diversion member 6 rotates to the point where the through hole is connected to the second water outlet 302, the water blocking structure 601 leaves the position of the first water outlet 306, and the first water outlet 306 is in an open state. At this time, the external water source flows into the water diversion tank 307 through the first water outlet 306, and then flows into the water collection tank 3 through the second water outlet 302; when the water diversion member 6 rotates to the point where the through hole is connected to the third water outlet, the water blocking structure 601 blocks the first water outlet 306, and the first water outlet 306 is in a closed state, so that the external water source no longer flows into the water diversion tank 307, the water inlet is completed, and the water circuit is switched to another mode.

[0046] When the dishwasher is not in operation, the through hole stays at the position connected to the third water outlet, and the water blocking structure 601 keeps blocking the first water outlet 306, thereby closing the external water source in turn. The water diversion valve assembly can control the on and off of the external water source, and can also switch between different waterways, and the two functions do not affect each other. The dishwasher using the water diversion valve assembly provided in this embodiment does not need to be provided with a water inlet solenoid valve, which can reduce the cost of parts and installation costs, and increase the base space of the dishwasher.

[0047] In another embodiment, the first water outlet 306 is used to communicate with the water spray structure of the enhanced washing area, the second water outlet 302 is used to communicate with the water channel inlet of the lower spray arm, and the third water outlet is used to communicate with the water channel inlet of the upper spray arm or the water channel inlet of the middle spray arm. When the second water outlet 302 is opened, the first water outlet 306 is opened, and the water spray structure of the enhanced washing area and the lower spray arm spray water. When the third water outlet is opened, the first water outlet 306 is blocked by the water blocking structure 601, and the water spray structure of the enhanced washing area is closed to realize the water channel control of the enhanced washing area to prevent the water spray structure of the enhanced washing area from dividing the pressure when the middle spray arm or the upper spray arm rotates.

[0048] The water-dividing puller 6 may be in a block shape or in a plate shape. In the present embodiment, the water-dividing puller 6 is in a plate shape.

[0049] When the first water outlet 306 is used to connect with the water spray structure of the enhanced washing area, the second water outlet 302 is used to connect with the water channel inlet of the lower spray arm, and the third water outlet is used to connect with the water channel inlet of the upper spray arm or the water channel inlet of the middle spray arm, the water blocking structure 601 can be an arc-shaped water blocking plate, and the water blocking plate can fit with the side wall of the water diversion trough 307, so that the water blocking plate blocks the first water outlet 306.

[0050] The first water outlet 306 is used to communicate with an external water source, the second water outlet 302 is used to communicate with the inlet of the water collecting tank 3 of the water diversion valve assembly, and the third water outlet is used to communicate with the water channel inlet of the water collecting tank 3 of the water diversion valve assembly. In order to improve the sealing of the first water outlet 306, the following scheme can be adopted: a first water passage 303 is provided on the outside of the first water outlet 306; a bead 2 is provided in the first water passage 303, one end of the bead 2 extends out of the first water outlet 306, and the bead 2 can move axially along the first water passage 303; the inner side wall of the first water passage 303 has an annular protrusion, and a first sealing ring 5 is provided on the side of the annular protrusion facing the bead 2; the water blocking structure 601 can drive the bead 2 to move toward the first sealing ring 5 so that the bead 2 squeezes the first sealing ring 5.

[0051] When the water diversion member 6 rotates to the position where the through hole is connected to the third water outlet, the water blocking structure 601 is at the position of the bead 2. At this time, the water blocking structure 601 squeezes the bead 2 into the first water passage 303. The bead 2 and the annular protrusion compress the first sealing ring 5, thereby closing the first water passage 303 and then closing the first water outlet 306.

[0052] The annular protrusion may be integrally formed with the first water passage 303 , or the annular protrusion may be fixed inside the first water passage 303 .

[0053] Preferably, the water diversion valve assembly further comprises a sleeve 4; one end of the sleeve 4 extends into the first water passage 303, and a second sealing ring 1 is provided between the sleeve 4 and the first water passage 303; one end of the sleeve 4 extending into the first water passage 303 forms an annular protrusion.

[0054] The sleeve 4 is fixed to the first water passage 303, the sleeve 4 is communicated with the first water passage 303, and one end of the sleeve 4 extending into the first water passage 303 forms an annular protrusion, which is easy to install, simple in structure, and convenient for disassembly and assembly.

[0055] The connection between the sleeve 4 and the first water passage 303 may be a fixed connection, such as bonding or welding, or a detachable connection, such as a snap connection or a threaded connection.

[0056] The water diverter 6 can be driven to rotate manually or by the driving device 14 .

[0057] Furthermore, the water diversion valve assembly also includes a cover plate 11 and a driving device 14 ; the cover plate 11 covers the opening of the water diversion tank 307 , and a driving shaft of the driving device 14 passes through the cover plate 11 and is connected to the water diversion member 6 .

[0058] The driving device 14 may be an electric motor or a hydraulic motor.

[0059] The driving shaft of the driving device 14 is fixedly connected to the water diversion paddle 6 to drive the water diversion paddle to rotate around the axis of the water diversion groove 307 .

[0060] The cover plate 11 covers the opening of the water dividing tank 307 to isolate the motor outside the water dividing tank 307 .

[0061] Furthermore, an elastic member 7 is provided between the cover plate 11 and the water diversion member 6 , and the elastic member 7 is in a compressed state so that the water diversion member 6 fits against the bottom wall of the water diversion groove 307 .

[0062] The elastic member 7 can be a spring or an elastic pad in any suitable form. The elastic member 7 makes the water diverter 6 fit the bottom wall of the water diverter groove 307 so that the water diverter 6 has good blocking performance for the second water outlet 302 and the third water outlet.

[0063] In this embodiment, the elastic member 7 is sleeved on the outside of the linkage shaft 9 , one end of the elastic member 7 abuts against the cover plate 11 , and the other end of the elastic member 7 abuts against the water diversion member 6 .

[0064] Furthermore, the driving shaft of the driving device 14 is connected to the water diversion member 6 via the linkage shaft 9 , a third sealing ring 8 is provided between the linkage shaft 9 and the cover plate 11 ; a fourth sealing ring 10 is provided between the cover plate 11 and the water diversion groove 307 .

[0065] One end of the linkage shaft 9 is fixedly mounted on the driving shaft of the driving device 14, and the other end of the linkage shaft 9 is connected to the water diversion member 6. The driving device 14 drives the linkage shaft 9 to rotate around the axis of the water diversion groove 307, and the linkage shaft 9 drives the water diversion member 6 to rotate around the axis of the water diversion groove 307.

[0066] The other end of the linkage shaft 9 and the water diverter member 6 may be fixedly connected, for example, by bonding or welding, or detachably connected, for example, by snap-fitting or threading.

[0067] In this embodiment, the water diverter 6 is provided with a clamping groove, and the other end of the linkage shaft 9 is provided with a clamping boss 901 , and the clamping boss 901 is clamped with the clamping groove.

[0068] By providing the third sealing ring 8 and the fourth sealing ring 10 , the sealing performance inside the water dividing groove 307 can be improved.

[0069] Furthermore, the driving shaft of the driving device 14 is connected to the water diversion member 6 through the linkage shaft 9, and the linkage shaft 9 is provided with a positioning member 902, and the positioning member 902 is located on the side of the cover plate 11 away from the water diversion groove 307; a positioning detector 12 is provided on the outer side of the positioning member 902, and the positioning detector 12 can detect the position information of the positioning member 902.

[0070] The positioning detector 12 may be a micro switch or a photoelectric sensor.

[0071] Specifically, the driving device 14 and the positioning detector 12 are installed on the motor fixing member 13 , the click fixing member is installed on the cover plate 11 , and the cover plate 11 covers the opening of the water distribution tank 307 .

[0072] When the water diverter 6 rotates, the linkage shaft 9 rotates synchronously with the water diverter 6 , the positioning member 902 on the linkage shaft 9 rotates synchronously with the water diverter 6 , and the position detector detects the position information of the positioning member 902 , thereby realizing the positioning of the water diverter 6 .

[0073] In this embodiment, the positioning member 902 is a boss, and the positioning detector 12 is a micro switch. The boss can trigger the micro switch to achieve the positioning of the water diverter blade.

[0074] Furthermore, there are multiple third water outlets 305, and the multiple third water outlets 305 are arranged at intervals along the circumference of the water dividing groove 307; when the through hole rotates from a position connected to any third water outlet 305 to a position connected to another third water outlet 305, the water blocking structure 601 always blocks the first water outlet 306.

[0075] The number of the third water outlets 305 can be any suitable number such as two, three or four.

[0076] Taking the example that the number of the third water outlets 305 is two, one of the third water outlets 305 is the third water outlet A301, and the other third water outlet 305 is the third water outlet B304. The through hole switches between the third water outlet A301 and the third water outlet B304, so as to realize the switching of different water paths. When switching, the driving device 14 switches between forward rotation and reverse rotation, so that the water blocking structure 601 will not leave the position of the bead 2, so that the first water outlet 306 always remains in a closed state.

[0077] Furthermore, there are multiple first water outlets 306, which are arranged at intervals along the circumference of the water diversion groove 307; there are multiple water blocking structures 601, which are arranged at intervals along the circumference of the water diversion member 6; the multiple water blocking structures 601 can be blocked one by one with the multiple first water outlets 306.
