Furthermore, it should be noted that, although the above embodiment describes a piping assembly including three nozzles, this is not a limitation on the number of nozzles of the piping assembly, and the piping assembly may include other numbers of nozzles. For example, the pipeline assembly may have four nozzles, and when the pipeline assembly has four nozzles, switching units may be respectively disposed at intersections of two adjacent nozzles with an included angle, so as to implement intercommunication between the opposite nozzles. It will be appreciated that the number of nozzles of the line assembly and the arrangement of the switching units may be suitably selected and adapted by a person skilled in the art according to the actual circumstances and needs.
With continued reference to fig. 1 and 2, the switching unit includes a connecting shaft 5, the connecting shaft 5 is disposed on a pipeline at the intersection of the first pipe orifice 1 and the second pipe orifice 2, and the connecting shaft 5 has a portion of an extension section extending out of the pipeline, the driving transmission mechanism is fixedly connected with the extension section of the connecting shaft 5, and the valve plug 4 is fixedly connected with a portion of the connecting shaft 5 located in the pipeline.

Since one part of the connecting shaft 5 is located inside the pipe and the other part is located outside the pipe, it is necessary to provide a sealing member at the pivotal connection portion of the connecting shaft 5 and the pipe, avoiding water overflowing from the pivotal connection portion. As a preferred embodiment, an annular groove can be provided along the circumference of the connecting shaft 5, and an annular projection can be provided correspondingly at a corresponding position on the pipeline, and the sealing of the pivotal connection of the connecting shaft 5 and the pipeline can be realized by the mutual clamping of the annular groove and the annular projection, without affecting the pivotal movement of the connecting shaft 5 relative to the pipeline. It will be appreciated that other suitable sealing members may be provided by those skilled in the art as the actual situation and need may dictate.
With continued reference to fig. 1 and 2, the drive transmission mechanism includes a drive mechanism 6 and a transmission mechanism 7, and the drive mechanism 6 is configured to be capable of forward and reverse rotation within a set range. Through the positive and negative rotation of actuating mechanism 6 in the settlement within range, connecting axle 5 drives valve plug 4 and rotates in corresponding angle within range to make the valve plug can rotate fast and accurately shutoff and open first mouth of pipe or second mouth of pipe, guaranteed valve plug pivoted stability and waterway switching's accuracy, improved the reliability of pipeline subassembly operation.
Preferably, the driving mechanism 6 is a rotating electric machine, and the rotating electric machine is provided with a travel switch, for example, the travel switch controls the driving mechanism to stop operating when the two farthest ends corresponding to the set range are located. It will be appreciated that the drive mechanism may also be in other forms, such as a servo motor, stepper motor, etc. It will be appreciated that the servo motor and stepper motor themselves have the function of controlling the range of rotation, so that there is no need to reconfigure the travel switch. Those skilled in the art can reasonably choose according to the actual situation and needs.
With continued reference to fig. 1 and 2, the transmission mechanism 7 is a crank-link mechanism, which includes a rotating member 71, a first link 72 and a second link 73 that are sequentially connected, the rotating member 71 is fixedly connected with an output shaft of the driving mechanism 6, and the second link 73 is fixedly connected with the connecting shaft 5. Taking the connection of the third water inlet 3 of the pipeline assembly with the water outlet of the drain valve of the washing machine as an example, the initial state is set to be the state that the valve plug 4 is in the state of plugging the first pipe orifice 1. When the washing machine needs to drain water into a sewer, the control module of the washing machine controls the driving mechanism 6 to act, the output shaft of the driving mechanism 6 drives the rotary member 71 to rotate, the first connecting rod 72 connected with the rotary member 71 also rotates along with the rotary member, the first connecting rod 72 drives the second connecting rod 73 to move, and the second connecting rod 73 is fixedly connected with the connecting shaft 5, so that the connecting shaft 5 is pivoted on a pipeline arranged at the intersection of the first pipe orifice 1 and the second pipe orifice 2, the second connecting rod 73 drives the connecting shaft 5 to perform pivoting movement relative to the pipeline, the valve plug 4 fixedly connected with the connecting shaft synchronously rotates along with the connecting shaft, and in the state that the valve plug 4 completely opens the first pipe orifice 1 and completely seals the second pipe orifice 2, the control module of the washing machine cuts off the power of the driving mechanism 6 through a travel switch, and at the moment, the drain valve is opened, and water drained from the washing machine can be drained out of the washing machine through the third pipe orifice 3 and the first pipe orifice 1. When the washing machine needs to recycle water, the controller of the washing machine controls the pipeline assembly to open the second pipe orifice 2, the first pipe orifice 1 is completely closed, and the water is led into the water storage device or the inner barrel through the third pipe orifice 3 and the second pipe orifice 2. The operation is similar to the drainage process for connecting the third nozzle 3 and the first nozzle 1, which is described above, and will not be described again.
For example, the rotary member 71 may be a cam or a connecting rod, and when the rotary member 71 is a cam, the first connecting rod 72 is connected to an eccentric shaft of the cam. The arrangement of the cam stabilizes the structure of the transmission mechanism and improves the operation reliability of the transmission mechanism. When the rotary member 72 is a connecting rod, a first end of the connecting rod is connected to the output shaft of the driving mechanism 6, and a second end of the connecting rod is connected to the first connecting rod 72. The connecting rod is light, the cost is lower, and the structure of the transmission mechanism is lighter. Through the arrangement, the rotation of the driving mechanism is converted into the up-and-down displacement of the first connecting rod, so that the second connecting rod is pushed or pulled to enable the connecting shaft to pivot relative to the pipeline, and finally, the valve plug performs fan-shaped movement with the central angle alpha in the pipeline, for example, the alpha can be any angle in the range of 90-180 degrees, for example, 120 degrees.
It should be noted that, although the transmission mechanism described in the above embodiment is a crank-link structure, this is not a limitation on the transmission mechanism. It will be appreciated that a person skilled in the art may provide a reasonable transmission mechanism according to the actual situation and needs, as long as it is possible to transmit the driving force of the driving mechanism to the valve plug, and to switch the functions of opening the second nozzle when the valve plug moves to a state where the first nozzle can be closed and closing the second nozzle when the valve plug moves to a state where the first nozzle can be opened.
