The outer tub 2 is connected with a drain pipe 82 for discharging water in the outer tub 2 to the outside of the washing machine; the master drain valve 83 is connected to the drain pipe 82, and when the master drain valve 83 is closed, the water flow in the outer cylinder 2 cannot be discharged, and when the master drain valve 83 is opened, the water flow in the outer cylinder 2 is discharged along the drain pipe 82.

When the washing machine drains water, both the drain valve 81 and the main drain valve 83 are opened, and the washing water in the drum 3 flows into the outer tub 2 from the drain valve 81 and is drained through the drain pipe 82. Compared with the prior art that the water flow is discharged by the centrifugal force generated by the rotation of the drum 3, the washing machine has the advantages that the drum 3 does not need to rotate during water discharging, and the energy consumption of the washing machine can be reduced.

In some embodiments, the washing machine may include a lifting rib 9 provided in the drum 3 for continuously lifting the fall-hit laundry to wash the laundry, and a drain valve 81 is installed in the lifting rib 9.

Specifically, a through hole may be formed in the lifting rib 9 and the drum 3, and when the drain valve 81 is opened at the through hole where the drain valve 81 is installed, the washing water in the drum 3 flows from the drain valve 81 to the outer tub 2 and is discharged.

In some embodiments, referring to fig. 4 and 5, the drum 3 is provided with a water outlet 32 at a position corresponding to the water discharge valve 81, the lifting rib 9 is provided with a through hole communicated with the water outlet 32, and the washing water in the drum 3 can flow to the water outlet 32 through the through hole and then flow out of the water outlet 32; the drain valve 81 may be a push-type rebounding structure, and an existing rebounder structure may be adopted, and the structure of the drain valve 81 is not described in detail herein, the drain valve 81 has an extended state (the drain valve 81 is closed) and a retracted state (the drain valve 81 is opened), and once pressed, the drain valve 81 can be extended to block the drain opening 32 (shown in fig. 4); once more pressed, the drain valve 81 is retracted to open the drain port 32 (shown in fig. 5), and the washing water can smoothly pass through.

The drain opening 32 of the drum 5 can be closed by pressing the primary drain valve 81, and the drain opening 32 can be opened by pressing the primary drain valve 81 again, so that the washing water in the drum 5 can be discharged, and the reliability is high.

In some embodiments of the washing machine of the present disclosure, with continued reference to fig. 3, the opening or closing of the drain valve 81 may be controlled by the switching motor 10, and the switching motor 10 is fixedly connected to the tub 2. The switching motor 10 has a retractable shaft, and the shaft can extend toward the drain valve 81 to perform an operation of pressing the drain valve 81, thereby opening or closing the drain valve 81.

The washing machine of the present disclosure does not occupy the space of the drum 3 by disposing the drain valve 81 in the lifting rib 9, and can achieve the purposes of compact structure of the drum 3 and maximized volume of the drum 3. In addition, the lifting rib 9 can be detached, and cleaning operation is convenient.

Specifically, the lifting ribs 9 provided in the drum 3 are provided in plurality and are uniformly distributed along the circumference of the drum 3, and each lifting rib 9 is connected with a drain valve 81. When draining, one of the lifting ribs 9 is located at the bottom end of the drum 3, which may facilitate draining of the washing water in the drum 3.
