Problems solved by technology

During the dehydration process of the washing machine, the material and amount of clothes dehydrated each time are often different. In order to ensure that the clothes of various materials and different amounts of clothes have a better dehydration effect, the control chip of the washing machine needs to be installed before the washing machine leaves the factory. The dehydration speed and dehydration time are fixed by uploading the control program, and the dehydration speed and dehydration time are obtained through experiments, which can make the dehydration of the most difficult clothi

Example Embodiment

[0039] Example 1

[0040] See figure 2 , The flow chart of the dehydration control method provides further details on increasing the motor speed in stages. After the dehydration starts, the control system first detects the current and speed of the motor in real time, and then keeps the motor speed constant. Calculate the change of the motor current. When the change of the motor current tends to zero, the motor speed is increased quantitatively to enter the next stage, in which whether the set laundry dehydration rate is reached is used as the dehydration end condition. In the case of ensuring the dehydration effect, the dehydration end condition can be one of the following conditions: the set total dehydration time, the set moisture content of the clothes, the set number of increments of the motor current, and the set motor speed. Number of increments. Among the listed dehydration end conditions, setting the moisture content of the laundry can most directly ensure that the dehy...

Example Embodiment

[0044] Example 2

[0045] Compared with Embodiment 1, the principle adopted in this embodiment is the same. Also during the dehydration process, the control system detects the current and speed of the motor in real time, and also adopts a stepwise increment method. Image 6 As shown, in this embodiment, in the same stage, the motor current remains constant, and the condition for the increase of the motor current is that the change in the rotation speed of the motor in the same stage tends to zero. Formula 1 and Formula 2 are also applicable to this embodiment, according to Formula 1 and Formula 2, and see Figure 7 with Figure 8 , The motor speed always increases during the whole dehydration process. Since the motor current remains constant in the same stage, it means that the motor output power is also constant. Therefore, when the motor speed reaches a certain value under the motor current, the amount of change will tend to At zero, it means that the dehydration effect is alre...

Abstract

The invention discloses an intelligent drying control method for a washing machine, and relates to the intelligent control technology for the washing machine. With adoption of the method, the problems in the present washing machine that the rotating speed of a motor is not matched with clothes during drying, the drying time is long and the loss of a motor is great are solved. According to the method, the drying process is divided into multiple stages by a control system; during one stage, a motor is controlled to operate at constant rotating speed or constant electric current; when the motor operates to achieve preset conditions of the stage, the control system improves the rotating speed or the electric current of the motor through quantitative control, so the motor comes to the next stage and operates; when drying completion conditions preset by the control system are met, the drying process is completed. The electric current or the rotating speed of the motor is adjusted in a staged quantitative manner, so that the rotating speed of the motor can be prevented from being overhigh after the drying operation starts; the motor can be adjusted timely when the drying degree of the clothes achieves the limit, so unnecessary operation time can be reduced, overhigh drying rotating speed can be avoided, drying time and motor loss can be reduced, electric consumption is saved.

Description

technical field [0001] The invention relates to a washing machine dehydration technology, in particular to a control method for intelligently adjusting the motor speed and dehydration time according to the torque of the washing machine motor. Background technique [0002] The dehydration method of the washing machine utilizes the centrifugal force generated when the drum rotates at high speed to separate and throw out the water from the clothes. During the dehydration process of the washing machine, the material and amount of clothes dehydrated each time are often different. In order to ensure that the clothes of various materials and different amounts of clothes have a better dehydration effect, the control chip of the washing machine needs to be installed before the washing machine leaves the factory. The dehydration speed and dehydration time are fixed by uploading the control program, and the dehydration speed and dehydration time are obtained through experiments, which ...
