Sensors in the application of the washing machine
Every family has a washing machine, but what you know about it? And the sensor in the washing machine will have what effect? Here we introduce the sensor in the washing machine
Will people get rid of the repeated operation of the washing machine, but followed by another wash rate problem. For a long time, washed by hand machine wash as deeply rooted in many people's mind. To a large extent, is due to the washing machine control chip and can not judge the clean degree of the washing, can according to time, according to the steps, according to methods such as washing, washing strength after perform all the procedures, as ending washing task. Caused the two phenomena, so one is machine clothing is not washed and termination procedures; Second, the clothing has washing clean and to carry out the washing procedure continues.
Now, smart way of washing gradually extended to higher areas, make judgement about washing washing machine can intelligence, thus to open different washing procedure become the subject of many research. Judgment to solve the washing machine, you need to join washing machine sensor system. So the sensor is widely used in a washing machine, thereby increasing the degree of intelligent washing machine.
Sensor is a kind of testing device, it can feel be measured information, and can detect feel the information, will change according to certain rule become electrical signal output, or other form of information needed to satisfy the information transmission, processing, storage, display, record and control requirements. It is the first step of automatic detection and automatic control, and more image is called "features".
For the washing machine, different sensor can realize the real-time monitoring of artificial as. Photosensitive sensor, for example, can detect liquid detergent QingZhuo degree, so as to determine whether clothes wash or rinse, can replace our eyes; The pressure sensor can automatically determine the weight of the clothes, the quantity was calculated detergent, is equivalent to our sense of touch; Humidity sensor can detect the degree of dry wet dry washing machine, so as to determine whether the clothes are dry, and the thermal sensor can sense the temperature inside the cylinder, so as to avoid the high temperature of drying burn clothing and so on.
The addition of sensors, can imitate human senses such as vision, hearing, smell, touch, and to determine the current state, according to the different senses has greatly increased the degree of intelligent washing machine. Now we can already see detergent on the washing machine automatic delivery, clothing clean degree detection, drying and so on intelligence operation, is inseparable from the sensor.
But it is worth mentioning that although sensor close to intelligence, but it is still faced with some problem. Only after all sensor devices, there are some misinformation behavior of false positives. , for example, if the surface is stained with moisture sensor, the sensor will think is very damp in the whole cylinder, so as to make the wrong judgment and wrong operation procedures. So, want to complete intelligent household appliances, there is a way to go.
