Referring to Figures 1-5, an embodiment of the dehydration bucket 100 of the present invention is shown.

The dehydration barrel 100 is composed of a cylindrical barrel wall and a barrel bottom. A number of drainage holes 110 are provided on the barrel wall and bottom of the dehydration barrel 100 . A drive motor is connected to the bottom of the dehydration barrel 100, and the drive motor can drive the dehydration barrel 100 to rotate. During the dehydration operation, the water removed from the washed clothes due to centrifugal action can be discharged from the dehydration barrel 100 through the drainage hole 110.

The inner wall of the dehydration barrel 100 is provided with an air guide step 120 on one side close to the drainage hole 110 . The drainage hole 110 is located on the front side of the air guide step 120 along the dehydration rotation direction. The inner surface of the air guide step 120 close to the center of the inner barrel forms a guide surface a. The guide surface a is inclined from the side away from the drainage hole 110 to the side close to the drainage hole 110 so that the air guide step 120 The side close to the drainage hole 110 is higher than the side away from the drainage hole 110 .

As shown in Figure 5, when dehydrating, the drainage hole 110 is regarded as an exhaust hole in the area not covered by clothing. When the dehydration barrel 100 rotates clockwise in the direction of the arrow in Figure 1 for dehydration, a counterclockwise air flow is formed in the barrel, and the drainage hole At 110, an outward airflow perpendicular to the barrel wall is generated. When the air guide step portion 120 is provided, the airflow in the barrel flows along the inclined guide surface of the air guide step portion 120, generating an air flow that is deflected toward the inside of the dehydration barrel 100, which can effectively cut the air flow and slow down the outward air flow at the drainage hole 110. The wind speed thereby reduces the whistle noise generated by the drainage hole 112. In addition, the air guide step portion 120 can also reduce the contact between the clothes and the drainage hole 110, reduce local pressure, and improve the strength of the dehydration bucket 100.

The above-mentioned dehydration barrel 100 can effectively cut the air flow during the dehydration process by arranging the air guide step 120 on the side of the drainage hole 110 of the dehydration barrel 100, slow down the wind speed of the outward air flow at the drainage hole 110, and effectively solve the noise caused by the whistle. , to improve the user experience; at the same time, the air guide step portion 120 can also reduce the contact between the clothes and the location of the drainage hole 110, reduce the local pressure, and improve the strength of the dehydration barrel 100.

In this embodiment, air guide step portions 120 are respectively provided on the left and right sides close to the drainage hole 110 , and the two air guide step portions 120 are arranged symmetrically with respect to the drainage hole 110 . In this way, when the dehydration barrel 100 rotates counterclockwise or clockwise, the air guide step portion 120 can play the role of air guide and deceleration. At the same time, the drainage hole 110 is located between the two opposite air guide step portions 120, which can effectively reduce the contact between the clothes and the position of the drainage hole 110.

Referring to FIG. 1 , the air guide step portion 120 extends axially along the inner wall of the dehydration barrel 100 to form a long structure, and a plurality of drainage holes 110 are spaced between the two opposite air guide step portions 120 .

Referring to Figure 5, the air guide surface of the air guide step portion 120 is an arc-shaped surface, and the airflow follows the arc-shaped guide surface a. The side of the air guide step portion 120 away from the drainage hole 110 can have a certain height difference or two height differences with the inner barrel wall. There is no height difference. In other embodiments, the air guide surface of the air guide step portion 120 may also be an inclined plane.

In this embodiment, the plurality of drainage holes 110 include at least two groups of drainage holes 110 with different diameters, and the drainage holes 110 with different diameters are staggered and arranged on the wall of the dehydration barrel 100 . During the spin dehydration process, the drainage holes 110 with different apertures can produce air columns of different sizes. The air columns of different sizes are less likely to resonate and can further eliminate whistle noise.

Referring to Figure 1, the drainage holes 110 in this embodiment include two groups of drainage holes 110 with different apertures, namely large drainage holes 111 and small drainage holes 112. The large drainage holes 111 and the small drainage holes 112 can be randomly distributed on the barrel wall.

The drainage holes 110 located on the same circumference of the side wall of the dehydration barrel 100 have the same aperture, and the drainage holes 110 on adjacent circumferences have different apertures. That is, in the up and down direction, large drainage holes 111 and small drainage holes 112 are arranged alternately, so that the large air column formed by the large drainage hole 111 and the small air column formed by the small drainage hole 112 can be arranged at intervals to reduce resonance.

Furthermore, the drainage holes 110 on the adjacent circumferences of the side walls of the dehydration barrel 100 are staggered up and down. That is, on adjacent circles (close to the horizontal direction), the large drainage holes 111 and the small drainage holes 112 are disposed in a staggered manner to prevent the upper and lower drainage holes 110 from being in close proximity, thereby improving the strength of the dehydration barrel 100 .

Referring to FIG. 5 , a protrusion 130 is also provided on the outer wall of the dehydration barrel 100 along the circumference of the drainage hole 110 . By providing the protruding portion 130, the local wall thickness at the drainage hole 110 can be made thicker than the wall thickness of the barrel, and the local strength of the dehydration barrel 100 can be improved. It can also effectively extend the air duct and easily form air columns. Air columns of different sizes are not easy to form resonance, which can effectively solve whistle noise.

Further, the drainage hole 110 extends outward along the inner wall of the dehydration barrel 100 to the outer wall of the dehydration barrel 100, and its inner diameter gradually expands from the inside to the outside, that is, an air duct that gradually expands from the inside to the outside is formed. After the airflow passes through the gradually expanding drainage hole 110, the wind speed becomes smaller, further reducing the noise.

The dehydration barrel 100 in this embodiment is formed into an integrated structure through injection molding, which has a simple structure and low manufacturing cost. The bottom of the dehydration bucket 100 can also be provided with drainage holes 110 with different diameters. Drainage holes 110 of different sizes are arranged at intervals on the same circumference of the bottom of the bucket.

The utility model also includes a kind of clothes processing equipment, and the clothes processing device includes the above-mentioned dehydration bucket. Clothes processing equipment includes but is not limited to pulsator washing machines, drum washing machines, clothes dryers, shoe washers, etc.

The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art can still implement the foregoing implementation. The technical solutions described in the examples are modified, or some of the technical features are equivalently replaced; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present utility model.
