Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, this embodiment discloses a dehydration control method for a multi-tubular washing machine. The washing machine of this embodiment includes a first washing tub 1, a second washing tub 2 and a control system. When the first washing tub 1 and the second washing tub 2 run dehydration programs at the same time, the control system adjusts the first washing tub 1 and / or the second washing tub. Second, the rotating speed of the washing drum 2 reduces the overall amplitude when the washing machine dehydrates.

[0040] In this embodiment, each washing drum has a plurality of different speed gears corresponding to different speeds, and these speed gears include 600 rpm, or 800 rpm, or 1200 rpm, or 1500 rpm. rpm.

[0041] Before the first washing tub executes the dehydration program, it is judged whether the second washing tub is performing the dehydration program; if not, the first washing tub controls the washing tub to perform the deh...

Embodiment 2

[0047] This embodiment is a supplement to Embodiment 1. In this embodiment, the second rotating speed is adjusted according to the eccentricity of the clothes to be dehydrated in the washing tub in the first washing tub. The second rotating speed and the eccentricity size is negatively correlated. The second rotation speed in this embodiment is no longer simply a certain rotation speed gear lower than the first rotation speed, but a dynamically changing value adjusted according to the eccentricity of the laundry to be dehydrated in the first washing tub in the washing tub. The change of the second rotational speed here is mainly to adapt to the change of the eccentricity in the washing tub, so that the washing tub can operate at the highest possible rotational speed in the range lower than the first rotational speed under the condition that the sloshing amount of the washing tub meets the application requirements. The dehydration is performed at the second rotational speed, so...

Embodiment 3

[0049] This embodiment is a supplement to the above embodiment. In this embodiment, the second rotational speed is adjusted according to the vibration amplitude of the washing machine, and the second rotational speed is negatively correlated with the vibration amplitude. The control of the second rotational speed in this embodiment no longer focuses on parameters such as the washing tub itself or the properties of the clothes, but on the vibration amplitude of the washing machine as a whole. During the dehydration process of the washing machine, in a certain speed range, the higher the rotation speed, the smaller the shaking produced by the washing tub; at the same time, for the power output, the dehydration of the first washing tub and the second washing tub are operated independently Each of the two dehydration processes will generate corresponding vibrations of a certain frequency during the dehydration process. For the overall vibration amplitude of the washing machine, it...

Abstract

The invention discloses a method for controlling dehydration of a multi-tubular washing machine and the washing machine. The washing machine includes a first washing tub, a second washing tub and a control system. When the first washing tub and the second washing tub run dehydration programs simultaneously, the control system adjusts the The rotation speed of the first washing tub and / or the second washing tub reduces the overall amplitude of the dehydration of the washing machine. The present invention can solve the problem that the vibration amplitude of the existing multi-tubular washing machines is too large when each drum is dehydrated at the same time through the software control system. The present invention can be realized without detecting various counterweights or adding too many auxiliary equipment. The modification work of the existing washing machine is small, which makes it possible to dehydrate multiple cylinders at the same time, reduces the overall processing time of clothes, improves the efficiency of washing, and improves the customer satisfaction rate.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a dehydration control method of a multi-tubular washing machine and the washing machine. Background technique [0002] The drum washing machine is the trend of household applications in the future, and it will wash cleanly without damaging the clothes. At present, the drum washing and drying machines on the market have only one washing bucket. With the improvement of people's quality of life, hygiene consciousness is also gradually improved, especially in household laundry washing, more and more people wash their clothes separately. For example, wash the inner and outer clothes separately, wash the clothes of babies and adults separately, wash the clothes of different colors separately or wash a small amount of clothes in time. Adopting the existing washing machine to meet the above methods will not only waste a large amount of energy and water, but also be difficult...
