Problems solved by technology

However, according to the method described in the patent, when the unbalanced amount is less than the severe unbalanced amount set by the program during the distribution process, it immediately enters the pre-dehydration and drying stage, which has a certain degree of randomness, and does not consider the influence of the rotational speed on the unbalanced amount.

Embodiment 1

[0063] Such as figure 2 As shown, the method for controlling the distribution curve of the washing machine before dehydration includes the following steps:

[0064] Set N and M to represent the flag code in the program, N represents the corresponding number of times to change the acceleration value in a single distribution, M represents the corresponding number of times to change the set eccentric value in the distribution, that is, N is the number of times to return to the second stage, and M It is the number of times through the second stage in a distribution, initial value: N=0; M=0, return to step (1), return N to zero, and M value remains unchanged, the maximum value of N can be set to 3, and the maximum value of M can be set It is set for the system, and the system sets the eccentric value corresponding to the M value.

Embodiment 2

[0075] Such as figure 1 As shown, the washing machine dehydration curve control method includes the following steps (see figure 1 S2 paragraph in):

[0076] (1) Control the inner cylinder to rotate at a speed of 400 revolutions per minute for 45 seconds (see figure 1 The S21 section in the corresponding F speed);

[0077] (2) Control the inner barrel to rotate at a speed of 93 revolutions per minute for 6 seconds (see figure 1 The S22 section in S22 corresponds to the C speed), at this time, the eccentric value is detected, and the detected eccentric value must be less than or equal to the system preset eccentric value, and the highest dehydration speed is determined according to the detected eccentric value;

[0078] (3) Gradually increase to the highest dehydration speed: maintain the speed of 600 rpm for 45 seconds (corresponding to figure 1 Middle G speed), maintain the speed of 800 revolutions per minute for 45 seconds (corresponding figure 1 Medium H speed), maintai...

Embodiment 3

[0082] The above pre-dehydration distribution is a random process, and the required time cannot be accurately predicted. In the process table of the washing machine, the time is usually not pre-allocated, that is, the time is stopped when the allocation is made. However, in order to prevent the distribution from being successful and the process from running downwards, you can limit the time without timing. In principle, this time is set at 5 minutes (it can be adjusted according to different programs and the highest set speed), that is, when the distribution time exceeds 5 minutes If it still fails, the timing will be forced to start, and then it will take up the inherent dehydration time until the dehydration time is also exhausted, then the pre-dehydration distribution fails this time, and it will transfer to the next washing process.

Abstract

The invention discloses a dehydration distribution control method of a washing machine. Before the washing machine is switched to a hydration function, the speed of an inner cylinder is controlled to be increased to a set rotating speed and stabilized at the set rotating speed, next, a process of repeatedly confirming an eccentric value of the load is added; the eccentric value of the load is repeatedly conformed before and after the rotating speed of the inner cylinder is controlled to be increased, and the eccentric value of the load is corrected after conforming that the eccentric value of the load satisfies a set condition; after hydration is began, the eccentric value is detected to determine the maximum dehydration rotating speed, the rotating speed is gradually increased to the hydration rotating speed and the hydration rotating speed is maintained for certain time for dehydration, next, the rotating speed is reduced to a certain rotating speed and maintained at the certain rotating speed for certain time, and then the rotating speed is increased to the hydration rotating speed again; by use of the method, the effects of steady dehydration, low vibration, low noise, low energy consumption and dehydration rate are achieved, and furthermore, the service life of a bearing, a speed reducer and the like of the washing machine is increased.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine control method, especially a washing machine dehydration distribution control method. Background technique [0002] Most of the distribution curves used by existing 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 loads, and sometimes even after a long time The distribution of the drum can not be evenly distributed in the end, and it cannot be dried normally, and even the use time is long, resulting in 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 improving the structure of the washing machine to obtain the effect of u...
