Problems solved by technology

However, since this method does not distinguish the effect of the speed of each stage in the acceleration process, it is difficult to balance the effect of homogenization and the required time: when the acceleration is small, the effect is good but the time is long; when the acceleration is large, the effect is poor if the time is short

Embodiment Construction

[0105] Embodiments are given below in conjunction with the accompanying drawings to further illustrate the roller control method proposed by the present invention.

[0106] Figure 5 It is the preferred embodiment 1 proposed according to the present invention, which includes specific implementation methods of decentralized operation, distributed operation, layered pressing, eccentricity detection, decision-making based on eccentricity detection, and pre-dehydration. In this example, the radius of the drum is 0.25 meters, and the speed curves in the homogenization and detection stages are as follows Figure 5 As shown, the process is as follows:

[0107] (1) The drum rotates at a speed of 42 (rev / min) for 8 seconds, about 5 to 6 circles, to achieve centrifugal dispersion operation.

[0108] (2) The drum rotates at a speed of 53 (rev / min) for 6 seconds, about 5 to 6 circles, in order to realize the impact dispersion operation.

[0109] (3) The drum accelerates to 64 (rev / min)...

Abstract

The present invention provides a uniformization method, eccentricity detection method and dewatering control method which can make the material in the drum washing machine and similar centrifugal dewatering equipment be uniformly distributed so as to reduce vibration and noise due to eccentricity. Said invention adopts a short-periodic power-on and power-off method of motor and collects rotating speed change due to eccentricity of drum which is rotated for a turn at 72-85 RPM to make detection of eccentricity, so that it can obtain good control effect.

Description

Technical field [0001] The invention relates to a dehydration control method of a drum type washing machine and a similar centrifugal dehydration device, especially a control method for uniformly distributing materials in the drum, a method for detecting the eccentricity of materials in the drum, and a method for operating according to different eccentricity degrees . Background technique [0002] Drum type washing machines, dehydrators and similar equipment have a common feature: there is an approximately cylindrical and drum-shaped container that rotates around a horizontal central axis—the drum, and the materials (such as clothing, etc.) inside are rotated at high speed around its axis. Realize functions such as centrifugal dehydration. In some equipment, the rotation axis of the rotating container is not horizontal, and forms a small angle with the horizontal plane, usually less than 30°. This situation is approximately horizontal. There is no difference between it and ...
