Embodiment Construction

[0036] The unbalance amount mentioned in the present invention corresponds to the unbalanced weight generated when the load distribution in the bucket is not completely uniform.

[0037] like Figure 5 As shown, it is a schematic diagram of the drum speed control curve. Its purpose is to make the clothes evenly distributed before drying. The drum speed control is implemented in the following four stages:

[0038] The first stage is the drainage stage S1. During the drainage process, the drum of the washing machine rotates clockwise and counterclockwise at a speed between 40 and 60 revolutions per minute. During this process, any rotation-to-stop ratio is used. The rotation speed needs to be determined according to the model. An optimal value (corresponding to Figure 5 in a speed);

[0039] The second stage, the counterclockwise rapid rise stage S2, the speed increases from the low speed drainage speed to 73 revolutions per minute. The speed increase at this stage must be re...

Abstract

The invention discloses a method for distribution control of a drum type washing machine before drying clothes, which comprises a speed at the beginning of water drainage stage, a low rotating speed of clockwise and anticlockwise rotation in the water drainage stage, a medium rotating speed after a rapid rising state through high-speed rotation in one direction and a high rotating speed after a slow rising stage in the direction identical to the direction of the previous stage. The amount of unbalance is judged after the high rotating speed is stable. When the amount of unbalance is larger than or equal to the amount of weight unbalance set in a program, the rotating speed is reduced to the low rotating speed in the water drainage stage, and the distribution is performed again from the second stage 5-6 seconds later, and if the pulse conditions can not satisfied after continuous distribution for three times, the distribution is performed again from the first stage. If the amount of unbalance is smaller than the amount of weight unbalance, the pre-hydrating and drying can be directly performed. The control method of the invention not only can achieve the best clothes distribution effect, thereby reducing the damage to the drum caused by displacement and centrifugal force resulting from uneven distribution, but also can greatly reduce the time before main drying and simultaneously save the electric energy.

Description

technical field [0001] The invention relates to a dehydration method of a washing machine, in particular to a method for controlling the distribution of clothes on the peripheral wall of an inner barrel of a drum washing machine before drying. Background technique [0002] Most of the distribution curves used by the existing drum washing machines cannot achieve the best distribution effect, especially for those objects that absorb a lot of water and have a small surface area, it is more difficult to distribute them well, such as bath towels, woolen sweaters and other clothes, and sometimes even after a long The distribution of time can't be evenly distributed at the end, and it can't be dried normally (see figure 1 and figure 2 ), or even use for a long time, causing abnormal vibration or displacement of the drum, which brings inconvenience to the user and wastes electric energy. In order to solve the above problems well, many manufacturers mostly adopt the scheme of impr...
