As shown in fig. 1 to 3, a tub of a washing machine according to the present invention includes an overflow passage 2 disposed outside the tub 1; a first opening 3 disposed in a wall of the tub 1; the first opening 3 is communicated with the overflow channel 2, the water-saving bucket further comprises a water baffle 4, the water baffle 4 and the wall of the water containing bucket 1 have a certain distance to form an overflow water path communicated with the first opening 3, and the overflow water path is arranged along the circumferential direction of the water containing bucket; the water baffle 4 comprises a first baffle 5 and a second baffle 6; preferably, the first baffle 5 and the second baffle 6 are smooth arc-shaped structures extending along the circumferential direction of the water barrel, and the arc-shaped structures ensure that the overflow water flow passes through effectively; further, the first baffle 5 and the second baffle 6 have a height difference along the radial direction of the water barrel, the height difference forms a second opening 7, and the second opening 7 ensures normal overflow of the water flow; furthermore, the second opening 7 is completely shielded by the projection of the tub wall of the water tub on the water baffle 4, so that the water flow cannot overflow from the second opening 7 during operation, and water source waste and insufficient washing effect are caused.

When the water level reaches the overflow water level, the excess water in the bucket can form an overflow drainage area from the overflow channel 2 from the overflow port to the drain pipe, the second opening 7 is completely shielded by the projection of the water containing bucket 1 on the water baffle 4, the second opening 7 is an opening for connecting the inside of the water containing bucket and the overflow channel 2, and when the overflow condition occurs, the excess water can flow to the overflow channel 2 from the second opening 7.

Further, the second opening 7 forms an opening connecting the overflow passage 2 with the inside of the tub, the second opening 7 communicating the first opening 3 with the overflow passage 2; the projection of the second baffle 6 on the wall of the water containing barrel is more than or equal to the width of the first opening 3, so that water flow cannot overflow from the second opening 7 during working, and water source waste and insufficient washing effect are caused; the first baffle 5 is equal to the overflow water level in height, and the second baffle 6 is higher than the overflow water level.

Due to the arrangement of the two-section type water baffle 4, when the new water flow washing machine works, waterfall type water flow is sprayed into the barrel from the outer barrel cover, the inner barrel rotates at high speed, the water flow continuously impacts the barrel wall of the water containing barrel, and when the waterfall water flow impacts the first opening 3, the water baffle 4 blocks the first opening 3, so that the sprayed water flow is blocked outside the overflow channel 2 and flows back to the inside of the water containing barrel from the new water flow.

When the water level is higher than the overflow water level, the excess water flows into the space between the water baffle 4 and the wall of the water barrel from the first opening 3, and when the water level exceeds the second opening 7, the water flows into the overflow channel 2 through the water baffle 4.

The invention adopts the structure of the two-section type water baffle 4 with staggered layout, thereby effectively avoiding the defects of water loss, low washing efficiency, large energy consumption and the like caused by the direct overflow of waterfall washing water flow from the first opening 3 in the working process of a new water flow washing machine; the water baffle 4 adopts a height difference structure to form the overflow channel 2, so that the overflow function is ensured while the overflow of water flow is further effectively avoided.

Example one

As shown in fig. 1 to 3, the tub of the present washing machine according to the present embodiment includes an overflow passage 2 disposed outside the tub 1; a first opening 3 disposed in a wall of the tub 1; the first opening 3 is communicated with the overflow channel 2, the water-saving bucket further comprises a water baffle 4, the water baffle 4 and the wall of the water containing bucket 1 have a certain distance to form an overflow water path communicated with the first opening 3, and the overflow water path is arranged along the circumferential direction of the water containing bucket; the water baffle 4 comprises a first baffle 5 and a second baffle 6; preferably, the first baffle 5 and the second baffle 6 are smooth arc-shaped structures extending along the circumferential direction of the water barrel, and the arc-shaped structures ensure that the overflow water flow passes through effectively; further, the first baffle 5 and the second baffle 6 have a height difference along the radial direction of the water tub, the height difference forms a second opening 7, and the second opening 7 ensures normal overflow of the water flow; furthermore, the second opening 7 is completely shielded by the projection of the tub wall of the water tub on the water baffle 4, so that the water flow cannot overflow from the second opening 7 during operation, and water source waste and insufficient washing effect are caused.

Further, the second opening 7 forms an opening connecting the overflow passage 2 with the inside of the tub, the second opening 7 communicating the first opening 3 with the overflow passage 2; the projection of the second baffle 6 on the wall of the water containing barrel is more than or equal to the width of the first opening 3, so that the water flow can not overflow from the second opening 7 during working, and the water source waste and the washing effect are not enough; the first baffle 5 has the same height as the overflow water level, and the second baffle 6 is higher than the overflow water level.

When the water level is higher than the overflow water level, the excess water flows into the space between the water baffle 4 and the wall of the water barrel from the first opening 3, and when the water level exceeds the second opening 7, the water flows into the overflow channel 2 beyond the water baffle 4.

Example two

As shown in fig. 1 to 3, in this embodiment, which is a further limitation of the first embodiment, the projection of the water baffle 4 on the tub wall of the tub in this embodiment is that the second baffle 6 is larger than the distance between the first openings 3.

EXAMPLE seven

In this embodiment, the water tub is mounted in a washing machine having a new water flow washing program, the new water flow washing program is configured to drive the inner tub to rotate unidirectionally at a higher rotation speed than that of the normal washing program, so that the water flow spirally rises along the outer tub and the inner tub to the outer tub cover, and is jetted from the outer tub cover to the inner tub, and therefore, the unidirectional rotation direction of the inner tub is opposite to the overflow direction of the overflow water path when the new water flow washing program is running.

When the water flow of the new water flow washing is collided with the first opening 3, the water flow is prevented from entering the overflow path 2 because the water baffle 4 blocks the first opening 3.

The water baffle does not affect the normal overflow protection function, when the water level is higher than the overflow water level, the redundant water flows into the space between the water baffle 4 and the wall of the water barrel from the first opening 3, and when the water level exceeds the second opening 7, the water flows into the overflow channel 2 by passing over the water baffle 4.
