Problems solved by technology

However, too high rotation speed of the inner drum will not only cause vibration and noise problems, but also excessive centrifugal force will cause water to stay between the inner drum and the outer drum and cannot return to the inner drum again, which is not conducive to the improvement of the cleaning degree.

Abstract

The invention discloses a drum washing machine. The drum washing machine comprises: an outer tub, the inner diameter of which is D; an inner tub, which is rotatably arranged in the outer tub; It is used to open and close the outer barrel; the water guiding structure is used to guide water into the inner barrel; wherein, the inner barrel rotates at a speed not higher than 11sqrt(D) for at least a period of time. According to the drum washing machine of the embodiment of the present invention, by limiting the maximum rotational speed of the inner tub, not only can the vibration and noise be reduced, but also the water guide structure that guides water into the inner tub can prevent water from stagnating between the inner tub and the outer tub , so that the water flow forms a cycle and continuously penetrates the clothes to improve the washing effect.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a drum washing machine. Background technique [0002] As a hands-free laundry equipment, washing machines are becoming more and more popular among consumers. Among the various performances of the washing machine, the washing degree of the clothes and a clean and healthy laundry environment are two particularly important items. [0003] For a drum washing machine, when the inner drum rotates at a higher speed, the water in the inner drum penetrates the clothes and the side wall of the inner drum due to centrifugal force and enters between the inner drum and the outer tub. It is generally believed in the art that the higher the rotation speed of the inner cylinder, the greater the centrifugal force, the better the penetration effect of water, and the higher the washing degree of the clothes. However, too high rotation speed of the inner drum will not only...
