Fig. 1 shows a schematic structure of an outer tub 1 of a washing machine according to an embodiment of the present utility model. Fig. 2 shows a schematic structural diagram of an installation position of a water bar 121 according to an embodiment of the present utility model. As shown in fig. 1-2, the present embodiment provides a washing machine, which includes an outer tub 1 and an inner tub 2, wherein a drain chamber is provided at the bottom of the outer tub 1, the inner tub 2 is rotatably provided in the outer tub 1, laundry to be washed can be contained in the inner tub 2, and a dehydration hole is provided on a sidewall of the inner tub 2. The washing machine of the present embodiment is mainly referred to as a drum washing machine.

When clothes are washed, the outer cylinder 1 is used for containing water, the inner cylinder 2 is used for containing the clothes, and the inner cylinder 2 can rotate relative to the outer cylinder 1 so as to perform beating washing on the clothes; meanwhile, the dewatering holes arranged on the inner cylinder 2 can enable water in the outer cylinder 1 to flow into the inner cylinder 2 through the dewatering holes so as to soak and wash clothes in the inner cylinder 2; the water in the inner cylinder 2 can flow out to the outer cylinder 1 through the dewatering holes and is discharged through the drainage cavity, thereby realizing the effects of washing and dewatering clothes. However, when the inner tub 2 rotates at a high speed with respect to the outer tub 1, a high-speed air flow is generated between the inner tub 2 and the outer tub 1, and water flowing out of the inner tub 2 to the outer tub 1 through the dehydrating holes rotates in synchronization with the air flow, so that it cannot smoothly flow into the drain chamber, affecting the dehydrating effect of the washing machine on laundry.

In order to solve the above problem, in the washing machine provided in this embodiment, the water blocking rib 121 is disposed on the inner wall of the outer tub 1, the water blocking rib 121 includes a water blocking surface 1211, and the extending direction of the water blocking surface 1211 is disposed at an angle with the tangential direction of the outer tub 1 where the water blocking rib 121 is disposed. When the washing machine performs a dewatering operation on clothes, water in the inner cylinder 2 can flow into the outer cylinder 1 through the dewatering holes, and water blocking ribs 121 arranged on the inner wall of the outer cylinder 1 can enable water flowing out of the dewatering holes to get rid of the influence of air flow so as to flow into the water draining cavity along the inclined water blocking surface 1211, thereby improving the water draining efficiency and ensuring the dewatering effect of the clothes; in addition, the air flow or the air-liquid mixed flow generated along with the high-speed rotation of the inner cylinder 2 can generate vortex at the position of the water blocking rib 121, and has the effect of flushing the cylinder wall near the water blocking rib 121, thereby realizing self-cleaning of the inner wall of the outer cylinder 1.

Alternatively, the angle between the extending direction of the water blocking surface 1211 and the tangential direction of the outer cylinder 1 where the water blocking ribs 121 are provided is 15 ° to 45 °. This design allows the water flow in contact with the water blocking surface 1211 to flow into the drainage chamber by the way. Illustratively, the angle between the extending direction of the water blocking surface 1211 and the tangential direction of the outer cylinder 1 where the water blocking ribs 121 are provided may be 18 °, 20 °, 25 °, 30 °, 42 °, or the like.

For convenience of description, taking the placing state of the washing machine in the home of the user as a reference, the user stands facing the switch door of the washing machine, at this time, one side close to the user is the front, one side far away from the user is the rear, the overhead direction of the user is the upper, the sole direction of the user is the lower, the left hand direction of the user is the left, and the right hand direction of the user is the right.

Further, the outer cylinder 1 comprises an upper cylinder 11 and a lower cylinder 12 which are connected, the upper cylinder 11 and the lower cylinder 12 are arranged symmetrically up and down relative to a horizontal plane passing through the axis of the outer cylinder 1, and water blocking ribs 121 are arranged on the lower cylinder 12. When the water in the inner cylinder 2 flows into the outer cylinder 1 from the dehydration holes, the water contacts with the water blocking ribs 121 and then flows into the drainage cavity along the water blocking surface 1211. The water blocking ribs 121 are arranged on the lower cylinder 12, so that the path between the water blocking ribs 121 and the drainage cavity can be shortened, and the drainage efficiency can be further improved.

Fig. 3 shows a schematic structural view of the outer cylinder 1 in an expanded state according to the embodiment of the present utility model. As shown in fig. 3, the number of the water blocking ribs 121 is plural, and the water blocking ribs 121 are spaced apart in the front-rear direction of the outer cylinder 1 so that water flowing into the outer cylinder 1 from each position of the inner cylinder 2 can be released from the action of the air flow and smoothly flow into the drainage chamber.

Alternatively, the inclination directions of each adjacent two of the water blocking ribs 121 are opposite in the front-rear direction of the outer tub 1. With this arrangement, a channel having a wide upper part and a narrow lower part can be formed between two adjacent water blocking ribs 121, thereby realizing the function of guiding water flow.

When the washing machine dehydrates clothes, the front flange connected to the inner cylinder 2 rotates at a high speed along with the inner cylinder 2, so that annular water flow is generated on the front flange and cannot be discharged from the dehydration holes, and after the dehydration operation is finished, water attached to the front flange falls back into the inner cylinder 2 again and is absorbed by the clothes, so that the phenomenon of water return is caused, and the dehydration effect of the clothes is affected. To solve this problem, in the present embodiment, the interval between adjacent two water blocking ribs 121 gradually increases in the front-rear direction of the outer cylinder 1. In this arrangement, the closely spaced water deflector bars 121 adjacent the front flange disrupt the annular flow of water, causing it to fall back into the inner drum 2 and be discharged from the dewatering holes. The distance between two adjacent water blocking ribs 121 specifically refers to the distance between the center positions of the two adjacent water blocking ribs 121.

Fig. 4 shows a second schematic structural view of the outer cylinder 1 in an expanded state according to the embodiment of the present utility model. As shown in fig. 4, the number of the water blocking ribs 121 is plural, and the plural water blocking ribs 121 are spaced apart along the circumferential direction of the outer cylinder 1 to prevent water flow from being carried away again by air flow during the process of flowing from the water blocking ribs 121 to the water discharge chamber. Alternatively, in the circumferential direction of the outer tub 1, the inclination directions of the adjacent two water blocking ribs 121 are the same or opposite.

In the present embodiment, two sets of water blocking ribs 121 are provided on the inner wall of the outer cylinder 1 in total along the circumferential direction of the outer cylinder 1, at three-point positions and nine-point positions of the outer cylinder 1, respectively (see fig. 2); each set of water blocking ribs 121 includes a plurality of water blocking ribs 121 spaced apart in the front-rear direction of the outer tub 1. Of course, the number of the water blocking ribs 121 is not limited in this embodiment, and the designer may adaptively adjust the number of the water blocking ribs 121 according to the length, the volume, and the like of the outer cylinder 1.

As shown in fig. 3 and 4, the water blocking rib 121 is in a long strip shape, and has a simple structure and is convenient to process.

Fig. 5 shows a third schematic structural view of the outer cylinder 1 in an expanded state according to the embodiment of the present utility model. As shown in fig. 5, the shape of the water blocking rib 121 may be a combination structure of various patterns, so long as the water between the inner cylinder 2 and the outer cylinder 1 can be removed from the action of the air flow to be smoothly guided into the drainage cavity, and the design can increase the aesthetic property of the outer cylinder 1.

Further, the water retaining rib 121 and the outer cylinder 1 are integrally formed, so that the processing is convenient, the time for mutually assembling a plurality of parts can be saved, and the processing efficiency is improved.
