Description
Technical field
The present invention relates to a kind of washing machine control panel senile experiment equipment and experimental method.
Background technology
Washing machine control panel senile experiment is identical with washing machine complete machine senile experiment, and exactly washing machine control panel is mounted in and washed
In clothing machine complete machine, the wash cycle experiment of 5000 times is carried out.Wherein, judgement of the washing machine control panel to water level height is to pass through frequency
For rate come what is perceived, height of water level more high water level frequency is lower, otherwise height of water level more low water level frequency is higher.Water level of washing machine passes
Sensor is according to the strong size of hydraulic pressure, produces different induction reactance, and due to the change of induction reactance in stagefrequency shakes loop, and
Produce different frequencies, referred to as stagefrequency.Washing machine control panel to the average value of water frequency by being acquired, Ran Houshi
Now washing control.One standard laundry requirements of process of washing machine enters water washing 1 time, water inlet rinsing 2 times.If 5 kilograms of laundries
Machine full load test, calculated by about 35 liters of each water inlet, the water that a washing machine requirements of process 35*3=105 rises.5000 times,
Then need to use water：5000*105=525000 liter=525 ton water.If to 10 washing machines --- 10 sections of washing machine control panels enter
Row senile experiment, then whole experiment need more than 5000 tons of water, and which results in serious water resource waste.For using water wisely, everybody
Design a lot of ways, water resource recycling system then occur.One kind is being collected into a pond after used water filtration
