Abstract

The present invention relates to an attached block structure for an inner barrel of a washing machine. The attached block structure is of a thin wall structure, which is installed on an inner wall of the inner barrel of the washing machine, a series of bulge structures ( 1 ) are arranged on one side of the thin wall structure facing interior of the inner barrel of the washing machine, and the bulge structures ( 1 ) are distributed along curves. The attached block structure for the inner barrel of the washing machine increases the rolling strength of washing water; and meanwhile, the bulge structures ( 1 ) additionally arranged on the attached block structure can not only realize a better rubbing and kneading effect on clothes, but also realize a certain three-dimensional water flow effect, thereby improving the washing cleanness, and having better user experience.

First claim

What is claimed:

1. An attached block structure for an inner barrel of a washing machine, comprising: a thin wall structure, which is installed on an inner wall of the inner barrel of the washing machine; a series of bulge structures arranged on one side of the thin wall structure facing an interior of the inner barrel of the washing machine, the bulge structures being distributed along curves;
wherein the bulge structures are symmetrically distributed about a center of the thin wall structure;
wherein distribution curves of the bulge structures comprise a hyperbolic curve and a sine curve, and the hyperbolic curve is disposed at two sides of the sine curve;
wherein the sine curve is arranged along a diagonal line of the thin wall structure; a focal point of the hyperbolic curve is disposed on an X axis, one branch of the hyperbolic curve in −X axis direction is arranged at a left side of the sine curve, the other branch of the hyperbolic curve in +X axis direction is arranged at a right side of the sine curve, and an asymptotic line of the hyperbolic curve is the diagonal line of the thin wall structure provided with the sine curve, so that when the water flow rotates in the clockwise direction and in the counterclockwise direction, different directions of the acting force of the bulge structures are applied on the water flow to form a three-dimensional water flow.

2. The attached block structure for the inner barrel of the washing machine according to claim 1 , wherein an upper part of the thin wall structure is installed near a top of the inner barrel, and a lower part of the thin wall structure is installed near a junction between a bottom of the inner barrel and a drum body.

3. The attached block structure for the inner barrel of the washing machine according to claim 2 , wherein the thin wall structure is in a rectangular shape as a whole, a width is ⅕-⅔ of a length of the thin wall structure, and a thickness is 1/20-⅕ of the length of the thin wall structure; and a cross section of the thin wall structure is in an arc shape, and a lengthwise section of the thin wall structure is in a streamline shape.

4. The attached block structure for the inner barrel of the washing machine according to claim 1 , wherein the bulge structures and the thin wall structure are integrally injection-molded, and each bulge structure is in a hemispherical shape.

5. The attached block structure for the inner barrel of the washing machine according to claim 1 , wherein the quantity of the bulge structures is 10 to 30; and the bulge structures are respectively distributed along the hyperbolic curve and the sine curve.

6. The attached block structure for the inner barrel of the washing machine according to claim 5 , wherein the quantity of the bulge structures is 15 to 20.

7. The attached block structure for the inner barrel of the washing machine according to claim 1 , wherein the bulge structures are installed on the inner wall of the inner barrel of the washing machine by screws, a back of the thin wall structure is provided with screw studs for installing the screws, and an anti-shrinkage structure of each screw stud is concealed in the corresponding bulge structure.

8. The attached block structure for the inner barrel of the washing machine according to claim 1 , wherein the thin wall structure and the inner barrel of the washing machine are seamlessly installed.
