Description
Technical Field
The invention belongs to the technical field of washing machines, and particularly relates to a washing machine with a control rod not easy to frequently collide.
Background
The present washing machines are various, such as a pulsator full-automatic washing machine, a twin-tub washing machine, a drum washing machine, and a pulsator washing machine, wherein the pulsator washing machine is more widely used.
Based on the operating principle of the impeller type full-automatic washing machine, the inner barrel and the impeller need to rotate in the washing or dewatering process, the clothes are washed or the moisture in the clothes is dried, the clothes in the inner barrel can rotate along with the rotation of the inner barrel or the impeller, the clothes easily deviate from the position of the central shaft of the inner barrel in the rotating process and are distributed on one side of the inner barrel, so that the gravity center of the inner barrel deviates, the inner barrel rotating at high speed violently shakes or vibrates due to the action of centrifugal force, and then the whole washing machine including the outer barrel vibrates, the outer barrel easily collides with a control rod or a box body, not only can generate great noise, but also can possibly damage the washing machine, and the service life of the washing machine is.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 3, three distribution states of the top of the inner tub clothes after washing in the full load state of the prior art washing machine are shown, wherein fig. 1 shows a second distribution state in which the top of the inner tub clothes 3 ' are biased to be close to the side of the tub wall of the inner tub 1 ', fig. 2 shows a second distribution state in which the top of the inner tub clothes 3 ' are biased to be distributed between the center of the inner tub 1 ' and the tub wall of the inner tub 1 ', and fig. 3 shows a third distribution state in which the top of the inner tub clothes 3 ' are distributed at the center of the inner tub 1 '. For the above three distribution states after washing, the possibility that the washing machine collides with the control lever is as follows: the first distribution state > the second distribution state > the third distribution state, when the clothes on the top of the inner tub 1 are farther away from the center of the inner tub 1, the larger the swing amplitude of the inner tub 1 is, the larger the amplitude of shaking or vibration is, and the higher the possibility of colliding with the control lever is, therefore, in a fully loaded state, the clothes after washing should be avoided from being in the state shown in fig. 1.
In order to solve the above problems, the present invention provides a washing machine which is not likely to frequently collide a control lever in a full load state, as shown in fig. 4 to 6, the washing machine including: an inner barrel 1; the wave wheel 4 is arranged at the bottom of the inner barrel 1; the limiting structure 5 is arranged at the position of the opening of the inner barrel 1, and the limiting structure 5 is provided with a convex part protruding towards the center of the inner barrel 1 to drive the clothes 3 on the top of the inner barrel 1 to be far away from the barrel wall of the inner barrel 1 and to be uniformly distributed towards the center of the inner barrel 1. The limiting structure effectively avoids the phenomenon that clothes are easy to deviate from the center of the inner barrel and lean against the barrel wall of the inner barrel to be distributed or gather at one side of the barrel wall of the inner barrel in the working process of the traditional washing machine, so that the inner barrel generates violent shaking or vibration in the rotating process, and even the phenomena of barrel beating, collision of the outer barrel against the box body and collision of a control rod are caused.

Or, the limiting structure 5 is an annular structure, the limiting structure 5 has an annular convex part protruding towards the center of the inner barrel 1 as a whole, the whole annular convex part enables the clothes 3 to be better and more uniformly distributed in the central area of the inner barrel 1, and the condition that the clothes 3 are gathered and attached to the local position of the barrel wall of the inner barrel 1 can be avoided, so that the swinging amplitude of the inner barrel 1 is smaller, the vibration or shaking amplitude is smaller, the barrel beating occurs, the probability that the outer barrel collides with the box body and the control rod is smaller, and the use experience of customers is improved.
The invention ensures that the washing machine runs more stably, the vibration or shaking amplitude is smaller, the noise is low, the probability that the outer barrel collides with the box body and the control rod is smaller when the barrel is beaten, and the service life of the washing machine is longer by arranging the limiting structure 5 at the opening of the inner barrel 1.
