[0002] Smart appliances are those that can replace household chores, improve living conditions, and enhance material well-being. Washing machines are one of the most common smart appliances. Currently, smart washing machines only require users to place clothes in the machine, while the laundry detergent, softener, and other detergents are added automatically.

[0003] Currently, smart washing machines automatically add detergent by using a pump to extract detergent from a dispenser and feed it into a water inlet channel. Water flowing through the inlet channel then carries the detergent into the washing drum. In commercially available smart washing machines, the pumps in the detergent dispenser typically correspond to the type of detergent to be added. Consequently, the detergent dispenser typically requires multiple pumps, resulting in a bulky and costly system that reduces the size of the smart washing machine. Furthermore, maintenance of the washing machine requires the inspection of each pump, resulting in high maintenance costs.

[0057] like Figure 4 As shown, the fluid switching mechanism includes a fluid switching component 6, a driving component 4 and a transmission component 5.

[0058] like Figure 5 As shown, two groups of fluid switching components 6 are respectively arranged in the liquid path switching chamber 16 and the water path switching chamber 19 , and each group of switching components 6 includes a main shaft 61 , a moving plate 62 and a static plate 63 .

[0059] The main shaft 61 includes a support plate 611 and a transmission shaft 612. The transmission shaft 612 is disposed on the bottom surface of the support plate 611. A liquid storage tank 613 is disposed on the top surface of the support plate 611. The side and top surfaces of the liquid storage tank 613 are open. The lower end of the transmission shaft 612 is connected to the drive assembly 4 via the transmission assembly 5. A protruding shaft 614 and a stopper protrusion 615 are disposed on the top surface of the support plate 611.

[0060] The bottom surface of the movable plate 62 is provided with an axis groove 621 and a limiting groove 622. The axis groove 621 and the limiting groove 622 are respectively adapted to the protruding shaft 614 and the limiting protrusion 615. The movable plate 62 is fixed to the top surface of the main shaft 6 by the protruding shaft 614 and the axis groove 621, and the limiting protrusion 615 and the limiting groove 622. The movable plate 7 is provided with a lower switching port 623 that communicates with the liquid storage tank 613. The lower switching port 623 is set through the movable plate 62.

[0061] The static piece 63 is arranged opposite to the moving piece 62, and a smooth static sealing surface is provided on the opposite end surfaces of the moving piece 62 and the static piece 63. The static piece 63 is provided with a plurality of upper switching ports 631, which are arranged one-to-one with the detergent inlet hole 15 or the water outlet hole 18.

[0062] A spring 64 is sleeved between the main shaft 61 and the movable plate 62. The two ends of the spring 64 are respectively against the movable plate 62 and the support plate 611. The spring 64 presses the movable plate 62 and the static plate 63 to improve the sealing performance of the static sealing surface of the movable plate 62 and the static plate 63.

[0063] A sealing gasket 7 is provided between the static piece 63 and the base 1. A limiting hole 71 is provided on the sealing gasket 7. A limiting ridge 632 that matches the limiting hole 71 is provided on the top surface of the static piece 63. The sealing gasket 7 is sleeved on the static piece 63 through the limiting hole 71 and the limiting ridge 632.

[0064] The drive assembly 4 is connected to the switching assembly 6, driving the switching assembly 6 to rotate until the lower switching port 623 aligns with different upper switching ports 631, thereby connecting the liquid storage tank 722 to different detergent inlet holes 15 or water outlet holes 18. The drive assembly 4 includes a drive motor 41 and a drive gear 42 mounted on the motor shaft of the drive motor 41.

[0065] The transmission assembly 5 is a transmission gear or a transmission gear set, which meshes with the driving gear 42 to transmit the rotation of the driving gear 43 to the transmission shaft 721 .

[0066] The fluid switching mechanism also includes a switching state indicator mechanism 8, comprising a switching wheel 81 and a microswitch 82. The switching wheel 81 is mounted coaxially with the drive gear 42. The switching wheel 81 is provided with a plurality of claws 83, each corresponding to the fluid outlets 61 on the switching plate 6. The claws 83 protrude outward from the outer surface of the drive wheel 81. The microswitch 82 is mounted on one side of the switching wheel 81. As the switching wheel 81 rotates, the claws 83 actuate the microswitch 82. The microswitch 82 is connected to a switching state signal circuit. The rotation of the switching wheel 81 causes the claws 83 to actuate the microswitch 82, switching it on or off, thereby outputting a state switching signal. The microswitch 82 is provided with a lever 84, which is rotatably mounted on the microswitch 82. As the drive gear 42 rotates, the lever 84 abuts the claws 83 or falls into the gap between the claws 83, switching the microswitch 82 on or off.

[0067] The working process of the present invention is as follows:

[0068] The various detergent containers and water inlet pipes are connected to a plurality of liquid inlet nozzles 21. The main water inlet pipe is connected to the main water inlet nozzle 110. A plurality of water outlet nozzles 22 are connected to the respective water outlets of the main unit. The liquid inlet nozzles 21 include, but are not limited to, detergent dispensers, softener dispensers, and water inlet nozzles. The water inlet nozzles can be used to flush out residual detergent in the liquid collection channel 11, preventing residual detergent from affecting the washing effect. The water outlet nozzles 22 include, but are not limited to, main outlet, spray outlet, and condensation outlet, which are used to implement different washing modes of the washing machine.

[0069] The switching assembly 6 operates as follows: the driving motor 41 drives the driving gear 42 to rotate, causing the driving gear 42 to drive the transmission assembly 5, thereby driving the transmission shaft 612 on the main shaft 61 to rotate. As the movable plate 62 rotates with the main shaft 61, the lower switching opening 623 on the top surface of the movable plate 62 aligns with different upper switching openings 631 on the static plate 63. This allows different liquid inlet nozzles 21 to communicate with the liquid storage chamber 613 through the detergent inlet hole 15, the upper switching opening 631, and the lower switching opening 623, or allows different water outlet nozzles 22 to communicate with the liquid storage chamber 613 through the liquid outlet hole 18, the upper switching opening 631, and the lower switching opening 623. This allows the liquid inlet nozzle 21 to communicate with the liquid path switching chamber 16, and the water outlet nozzle 22 to communicate with the water path switching chamber 19.

[0070] When the movable plate 62 in the liquid switching chamber 16 rotates to connect the lower switching port 623 with the upper switching port 631, detergent can enter the liquid inlet channel 14 through the corresponding liquid inlet nozzle 21, and then pass through the detergent inlet hole 15, the upper switching port 631, and the lower switching port 623 in sequence, and enter the liquid storage tank 613. When the liquid pump 3 is working, the detergent in the liquid switching chamber 16 enters the liquid collecting channel 11 through the liquid extraction hole 112 under the suction force of the liquid pump 3, and is then transported by the liquid pump 3 to the liquid outlet channel 12, and then enters the water outlet channel 17 connected to the liquid outlet channel 12.

[0071] The main water inlet enters the liquid storage tank 722 in the water channel switching chamber 19 through the main water inlet nozzle 10, and the movable plate 62 in the water channel switching chamber 19 switches to the lower switching port 623 and the upper switching port 631 to connect with the water channel switching chamber 19. The detergent mixes with the inlet water and is discharged from the corresponding water outlet nozzle 22.

[0072] The liquid collecting channel 11 and the liquid outlet channel 12 are independent of each other and are connected only by the liquid pump 3. Therefore, when the liquid pump 3 is not working, the detergent in the liquid collecting channel 11 cannot enter the liquid outlet channel 12. There is no need to worry about the drive motor 41 driving two sets of fluid switching mechanisms at the same time, causing the detergent to mistakenly enter the liquid outlet channel 12 and cause the detergent to be incorrectly dosed.

[0073] The switching state indicator mechanism 8 is used to indicate the switching state of the switching assembly 6 within the switching mechanism. When the drive motor 41 drives the switching assembly 6 to rotate via the drive gear 42 and the transmission assembly 5, the switching wheel 81 rotates a certain angle along with the drive gear 42, causing the pole claw 83 to abut against the lever 84. The lever 84 triggers the microswitch 82 to the on state. When the drive gear 42 rotates until the lever 84 falls into the gap between two adjacent pole claws 83, the microswitch 82 is disconnected. Based on the on-off state of the microswitch 82, the switching state signal circuit connected to the microswitch 82 can output a pulse signal representing the output state. The washing machine control device controls the drive motor 41, the liquid pump 3, the water outlet valve, and other components of the washing machine based on the output state switching signal, thereby achieving automatic operation of the washing machine.

[0074] Compared to the prior art, the fluid switching device for the liquid dispensing mechanism of an intelligent washing machine provided by the present invention utilizes a motor and a transmission assembly to drive a switching member to rotate, thereby connecting the reversing port on the switching member to different switching ports. This allows different detergents to communicate with the inlet of a liquid pump, enabling automatic addition of different detergents via the liquid pump. This invention eliminates the need for multiple liquid pumps based on the type of detergent, significantly reducing the cost of the detergent dispensing device for intelligent washing machines and reducing the size of the automatic detergent dispensing device, making it suitable for a variety of intelligent washing machine models. This expands the scope of application of the automatic detergent dispensing device and improves the maintenance ease of the detergent dispensing device.

[0075] The present invention realizes the dispensing of different detergents and the switching of different water outlet modes simultaneously through only one set of motors, thereby greatly reducing the production cost of the fluid switching device of the liquid dispensing mechanism of the intelligent washing machine.

[0076] In the present invention, the switching assembly includes a main shaft, a moving plate fixed on the main shaft, and a static plate arranged in the switching cavity. A flat seal is formed by static sealing surfaces on the opposite end faces of the moving plate and the static plate, which effectively avoids the impact or corrosion of the sealing surface by fluid pressure and detergent, causing leakage of detergent or water outlet, and has high sealing reliability.

[0077] In the present invention, a switching device indicating mechanism is provided on the fluid switching mechanism, and the switching state indication includes a switching wheel provided on the driving gear and a micro switch provided on one side of the switching wheel. The pole claw on the switching wheel abuts or separates with the lever of the micro switch, and outputs an indicating pulse signal of the switch state, thereby facilitating the control module of the washing machine to control the driving motor, liquid pump, etc. according to the state of the switch, thereby realizing automatic control of the water inlet and outlet and detergent addition of the washing machine.

[0078] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the scope of protection of the present invention.
