[0024] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0025] Please see Figure 1-4 A water inlet switching mechanism for a twin-tub washing machine includes a body 1, within which a washing tub and a spin-drying tub are respectively disposed. A switching mechanism 2 is provided on the body 1. The switching mechanism 2 includes a water tank 21, on which a water inlet 22, a first water outlet 23, and a second water outlet 24 are provided. The first water outlet 23 and the second water outlet 24 are respectively connected to the washing tub and the spin-drying tub. The mechanism also includes a converter 3 slidably connected within the water tank 21. The converter 3 has a first working position and a second working position: in the first working position, the converter 3 closes the second water outlet 24, and the water inlet 22 is connected to the first water outlet 23; in the second working position, the converter 3 closes the first water outlet 23, and the water inlet 22 is connected to the second water outlet 24. The mechanism also includes a control component 4, which is used to switch the converter 3 between the first and second working positions. The inlet 22 is connected to an external water source, and the first outlet 23 and the second outlet 24 can be connected to the washing tub and the spin-drying tub respectively through pipes.

[0026] Furthermore, the converter 3 includes a first slider 31 and a second slider 32 that are slidably connected within the water box 21, and the first slider 31 and the second slider 32 are fixedly connected by a fixing rod 33.

[0027] In the first station, the second slider 32 closes the second outlet 24, and at this time the inlet 22 is connected to the first inlet 22; in the second station, the first slider 31 closes the first outlet 23, and at this time the inlet 22 is connected to the second inlet 22.

[0028] Furthermore, a first sealing sleeve and a second sealing sleeve are respectively provided on the outer surfaces of the first slider 31 and the second slider 32 that contact the inner wall of the water box 21. This enhances the sealing capability of the first slider 31 and the second slider 32 for the first water inlet 22 and the second water inlet 22, and also restricts water movement to the area of ​​the water box 21 between the first slider 31 and the second slider 32.

[0029] Furthermore, the control component 4 includes a transmission plate 41 fixedly connected to the second slider 32, a transmission groove 42 formed on the transmission plate 41, a control rod 43 movably connected to the body 1, one end of the control rod 43 being fixedly connected to a cover plate 44, and the other end extending into the water box 21 and rotatably connected to a support block 45, a transmission rod 46 being fixedly connected to the support block 45, and the transmission rod 46 extending into and slidingly connected to the transmission groove 42. The transmission groove 42 is inclined.

[0030] Pressing the cover plate 44 causes the control rod 43 to slide along the body 1 and the water box 21. The movement of the control rod 43 drives the transmission rod 46 to move through the support block 45. Since the transmission groove 42 is inclined on the transmission plate 41, the movement of the transmission rod 46 will drive the transmission plate 41 to move through the transmission groove 42. The movement of the transmission plate 41 drives the converter 3 to move, so that the converter 3 can switch between the first station and the second station.

[0031] Furthermore, the control lever 43 passes through the support block 45 and is fixedly connected to a locking plate 47. A slot corresponding to the locking plate 47 is provided at the bottom of the water box 21. A compression spring 48 is provided between the cover plate 44 and the body 1, and the compression spring 48 is inserted on the outside of the control lever 43. This structure requires the user to continuously press the cover plate 44 to keep the converter 3 in the corresponding position, which is inconvenient. After pressing the cover plate 44 to move the converter 3 to the corresponding position (at this time, the control lever 43 drives the locking plate 47 to extend out of the slot from the water box 21), rotating the cover plate 44 causes the control lever 43 to rotate. The rotation of the control lever 43 causes the locking plate 47 to rotate. When the user releases the cover plate 44, under the reset action of the compression spring 48, the cover plate 44 moves the control plate to abut against the bottom of the water box 21, thus keeping the converter 3 in the current position for water intake.

[0032] It is worth noting that the movable connection between the control lever 43 and the body 1 is both a sliding connection and a rotating connection. This application provides a structure that can simultaneously realize the above two connection methods. A disc 5 is fixedly provided on the outer surface of the control lever 43. The disc 5 is rotatably connected to the body 1, and a sliding groove adapted to the disc 5 is provided on the body 1, so that the disc 5 can slide with the body 1 while maintaining a rotating connection with the body 1. This is a common technical means used by those skilled in the art. If those skilled in the art achieve this function through other structures without creative effort, it should also be considered within the scope of protection of this application.

[0033] Furthermore, an indicator block 49 is fixedly provided on the top of the cover plate 44, and the indicator block 49 is arranged parallel to the locking plate 47. The indicator block 49 is used to indicate the direction of the locking plate 47, so that the user can know the position of the locking plate 47, thereby facilitating the locking plate 47 to extend out of the water box 21 from the slot.

[0034] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
