Control method for reducing integral vibration of double-drum washing machine

Abstract

The invention provides a control method for reducing integral vibration of a double-drum washing machine. The washing machine comprises two washing buckets which are of up-down array structures. The control method has the advantages that a certain quantity of water is fed into one washing bucket to increase the weight of an integral outer drum assembly if only the other washing bucket runs, so that the integral gravity center of the double-drum washing machine can decline, and the amplitude of the integral vibration of the double-drum washing machine can be reduced; loads on the washing buckets are detected to determine the washing bucket with the quantity of loads if the two washing buckets are drained simultaneously, the washing bucket with the low quantity of loads is drained at first while the other washing bucket stalls, and the other washing bucket is used as a counterweight of the first washing bucket to reduce the integral vibration of the double-drum washing machine, and only starts to be drained after the first washing bucket is completely drained; the second washing bucket has the large quantity of loads, the gravity center of the second washing bucket is low, eccentricity of the loads of the second washing bucket can be adjusted easily, and accordingly excessive vibration can be prevented.

Description

technical field [0001] The invention relates to the technical field of washing machine control, in particular to a control method for reducing the overall vibration of a double-drum washing machine. [0002] Background technique [0003] With the progress of the times and the improvement of living standards, people's awareness of hygiene has gradually strengthened, and they have paid more attention to their own health. Many users have separated their clothes into different categories when washing clothes, washing inner and outer clothes separately, and washing baby and adult clothes separately. , Wash clothes with different levels of dirt and colors separately, etc. The resulting problem is that the amount of clothes washed each time is small, and the capacity of the washing machine cannot be fully utilized, resulting in waste of energy and water, which does not meet the requirements of environmental protection and energy saving. requirements, a double-drum washing machine...

Problems solved by technology

[0003] With the progress of the times and the improvement of living standards, people's awareness of hygiene has gradually strengthened, and they have paid more attention to their own health. Many users have washed their clothes Washing by classification, washing inner and outer clothes separately, washing baby and adult clothes separately, washing clothes with different degrees of dirt separately, washing clothes with different colors separately, etc. The problem brought about is that the amount of clothes washed each time is small, and the capacity of the washing machine cannot be fully utilized. Capacity, resulting in waste of energy and water, does not meet the requirements of environmental protection and energy saving. Double-drum washing machines can be used to meet the above requirements. At present, the double-drum washing machines commonly used in the market are upper and lower structures, and each layer is equipped with a washing bucket. The outer cylinders of the two washing tubs are fixedly connected as a box body, which protects the electronic components and mechanical components in the washing machine from physical impact, and prevents mechanical components from being damaged and impacted by users

However, due to the two drums arranged up and down, the height of the whole machine is much higher than that of a single-drum washing machine, and the amplitude increases accordingly, and resonance will be formed between the two drums, resulting in an increase in the amplitude of the whole machine, especially when the washing machine is running. During the dehydration process, there will be large vibration and noise, which will affect the service life of the machine for a long time
