Example one
The embodiment provides a method for adjusting the optimal rotation speed in the washing machine as shown in fig. 1, so that the washing machine can determine the rotation speed which is most suitable for the weight according to the weight of the clothes, the clothes can fall from the highest position, the optimal washing effect is achieved, and the washing time is saved.
Description of measurement of the rotating speed of the washing machine:
the rotation of the inner cylinder lifts the clothes to a certain height through the lifting ribs and the friction force on the inner cylinder wall, and along with the increase of the rotating speed, the centrifugal force of the inner cylinder increases, and the acting force on the inner cylinder wall also increases. In the washing process, the clothes can cling to the inner cylinder wall at an excessively high speed, so that a good washing effect cannot be achieved.
The method comprises the following steps:
the washing machine is powered on and started;
putting clothes and detecting the weight;
the weight of the washings in the revolving drum before water is not injected is detected, and whether the weight meets the maximum washing capacity of the washing machine or not is judged. If not: reducing the washings until the weight of the washings without soaking meets the machine standard;
if the following are met: selecting the material of the washings, injecting water into the rotary drum, soaking the washings to 80-95% of the water absorption weight according to the water absorption of the washings made of different materials, and starting the motor to rotate the rotary drum after the water absorption weight is reached;
measuring the pressure value of the rotating drum washings falling to the bottom of the rotating drum at the rotating speed V; judging whether the pressure value is the maximum pressure value N or notmax(ii) a If yes, the maximum pressure value N is usedmaxThe lower rotating speed is the optimal rotating speed; if not, increasing the rotating speed, and measuring the pressure value of the rotating drum washings falling to the bottom of the rotating drum again until the pressure value reaches the maximum pressure value Nmax。
The maximum pressure value NmaxThe determination method comprises the following steps: at a rotational speed VmThe pressure value of the washings falling to the bottom of the rotary drum of the lower measuring rotary drum is Nm(ii) a Increasing the rotational speed to Vm+1Measuring the pressure value N of the drum washings falling to the bottom of the drum at the rotating speedm+1(ii) a Judgment of NmAnd Nm+1The relationship of (1); if N is satisfiedm<Nm+1Continuously increasing the rotating speed, re-measuring the pressure value of the rotating drum washings falling to the bottom of the rotating drum and comparing the pressure value with the previous pressure value; if N is satisfiedm>Nm+1Then determine NmIs the maximum pressure value Nmax。
The specific operation process of the optimal rotating speed regulation method is as follows:
firstly, weighing clothes to determine whether the clothes meet the maximum washing capacity, then supplying water, stopping supplying water when the clothes absorb water to 80% -95%, and taking the weight of the state as the weight for measuring the optimal rotating speed of the washing machine. Assuming that the maximum washing capacity of the washing machine is 7KG, the weight of the washing machine when water is injected to 80% -95% is about 12.6 KG-13.65 KG according to different clothes materials.
Secondly, pre-rotation is carried out for a certain time by the weight after water injection to measure the optimal rotating speed. The inner cylinder is made to run for 30-80 circles at the initial rotating speed of 40-70/min, and the average value on the pressure sensor is measured; the range of the number of running turns and the starting rotational speed and the magnitude of the increase in the rotational speed are determined by different clothes materials.
Then, the rotating speed is increased by 10-50 r/min, the operation is carried out for 30-80 circles in the same way, whether the pressure value is the maximum value of different rotating speeds or not is judged, if the pressure value is the maximum value, the rotating speed at the moment is recorded, and if not, the step is repeated; the number of running turns at different rotational speeds must be the same.
And finally, when the rotating speed runs to the maximum value in the weight state, recording the pressure value, and stopping the operation of the inner cylinder. The rotating speed with the maximum pressure is taken as the optimal rotating speed, namely the rotating speed of the inner cylinder of the washing machine under the weight state. And determining whether water needs to be continuously injected according to the washing effect of different clothes under different water injection amounts. The motor is then restarted to run at the optimum speed.
The pressure value is preferably measured using a pressure sensor. The pressure sensor is used for measuring the pressure value when the clothes fall from a high place under a certain rotating speed to judge whether the rotating speed is the maximum acting force of falling. The pressure sensor is placed at the bottom of the roller body, a plurality of sampling accuracy increasing devices can be placed, the pressure value of the pressure sensor changes to a certain extent when the clothes fall at a certain rotating speed, and the pressure value of the pressure sensor is in the maximum state at the optimal rotating speed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
