Referring to fig. 5, the circulating part 50 is located at one end where the barrel 201 and the barrel bottom 202 are combined, and extends along the barrel 201 toward the barrel bottom 202. The circulation part 50 and the inner tub 20 are integrally formed, so that the manufacturing process can be simplified and the production efficiency can be improved.

The circulation portion 50 includes a circulation base 501 and circulation beads 502.

The circulation base 501 is located at the junction of the bowl 201 and the bottom 202. The circulation base 501 is arc-shaped, the axial section of the circulation base is approximately trapezoidal, and the distance between the inner surface of the circulation base and the axis of the inner barrel 20 is gradually decreased, that is, the circulation base 501 has a taper, so that a slope or an arc is used between the barrel body 201 and the barrel bottom 202 of the inner barrel 20. When the inner barrel 20 rotates at a high speed, water in the inner barrel 20 ascends through the inner surface of the circulating base body 501, falls down when the water in the inner barrel 20 climbs to a certain height, and sequentially circulates back and forth, so that the water in the inner barrel 20 continuously circulates, the water in the inner barrel 20 can be uniformly stirred, a detergent and the water can be fully mixed, meanwhile, the water in the inner barrel 20 continuously circulates and flows, foam generated in the washing process can be crushed, and the phenomenon that the excessive foam generated in the inner barrel 20 influences the washing can be avoided.

The circulation ribs 502 are provided on the inner surface of the circulation base 501 facing away from the tub 201. The plurality of circulation ribs 502 are provided, the plurality of circulation ribs 502 are arranged along the circumferential direction of the inner barrel 20 at intervals, and each circulation rib 502 is arranged along the height direction of the circulation base 501. The circulation ribs 502 protrude toward the inside of the inner tub 20, and facilitate water in the inner tub 20 to be attached to the sidewall of the inner tub 20 while climbing upward under the high-speed rotation of the inner tub 20.

The guide rib 40 is located on the inner wall of the tub 201, and protrudes toward the inside of the tub 201 in the radial direction of the inner tub 20. The guide rib 40 is provided in the axial direction of the tub 201 and below the drain hole 2011. When the inner tub 20 is drained to the outside, it is rotated at a high speed, and the guide ribs 40 guide the water in the inner tub 20 to ascend upward and be drained to the outside through the drain holes 2011. The guide ribs 40 are arranged in a plurality of numbers, and the guide ribs 40 are arranged at intervals along the circumferential direction of the barrel body 201, so that the guide ribs 40 are densely distributed in the circumferential direction of the barrel body 201, and the drainage speed can be increased. The guide rib 40 and the barrel body 201 are integrally formed, so that the production steps can be reduced, and the processing efficiency is improved.

The guiding ribs 40 are distributed on two sides of each drainage hole 2011, so that water between two adjacent guiding ribs 40 can be conveniently drained outwards through the drainage holes 2011 on the tops of the two guiding ribs.

The balance ring 60 is ring-shaped and has a contour that fits the top of the inner barrel 20. The balance ring 60 is fixedly installed at the top of the inner tub 20. The balance ring 60 is provided inside with a damping chamber (not shown) filled with high-density brine, and the high-density brine can flow in the damping chamber. When the inner tub 20 rotates at a high speed, the laundry in the inner tub 20 is accumulated at one side of the inner tub 20, and a large centrifugal force is generated, which causes the inner tub 20 to generate a large vibration. When the inner tub 20 rotates at a high speed, the liquid in the balance ring 60 rotates at a high speed with the inner tub 20 and generates a centripetal force to offset a portion of the centrifugal force of the inner tub 20, thereby reducing vibration of the inner tub 20. The freezing point of the high-density brine is lower than that of tap water, so that the probability of freezing of the high-density brine in winter is relatively low, and therefore, the high-density brine in the balance ring 60 can still flow in the damping cavity in winter, so that the balance ring 60 can still normally function in cold weather.

In summary, the present invention provides a pulsator washing machine 100, wherein the barrel body 201 and the barrel bottom 202 of the inner barrel 20 of the pulsator washing machine 100 are integrally formed, and the inner barrel 20 can be manufactured at one time, so that the inner barrel 20 can be manufactured by one set of equipment, and the manufacturing cost can be reduced. Compared with the prior art, the manufactured inner barrel 20 does not need to be assembled in a complex way, and the production efficiency of the inner barrel 20 can be improved.
