How does coin-operated washing machine work?

At present, coin-operated washing machine is used in many public places, such as our schools and factories. Because they don't need to be looked after by people, which reduces our labor management cost, they have become more and more widely used. Today, Xiaoruo will introduce coin-operated washing machine's principles and related knowledge.

With the continuous progress of science and technology, the pace of our life is getting faster and faster, and many products have appeared accordingly. Our coin-operated washing machine is also widely used in our public property, because it doesn't need people to watch, and it uses higher quality motors and corrosion-resistant raw materials.

Coin-operated automatic washing machines are very easy to operate. Its function is realized because it uses comparison coil, AD, detecting optical eye and coin feeding motor. When we put coins in it, the coins will pass through the sample, making the comparison coil respond to the comparison voltage, and the corresponding detection after shaping will be transmitted to the AD converter, and then enter the CPU after passing through the AD converter. The realization of the function of coin-operated washing machine mainly consists of four parts: oscillating circuit, electric door, photoelectric sensor and centralized control unit.

1, square oscillator circuit

The most important part of this module is the coil that can form high-frequency signals. When there is no iron in this coil, the transmission frequency of the high-frequency square wave oscillation circuit is quite stable, which is the same high-frequency signal. When iron exists, the inductance of the coil will change accordingly, thus changing the high-frequency information transmitted by the oscillator circuit. Only by passing these tests can we investigate the value of change, and we can distinguish real money from counterfeit money.

2, electric door drive

The electric door is a switching device controlled by a simple DC motor. Its function is to drive the small motor to run forward when it is recognized that the coin is real, so that the real coin slides into it. If it is not true, it will reverse the entrance of the coin and let the fake coin exit.

3. Photoelectric sensor

It is used to distinguish whether coins enter according to the set process, and consists of a plurality of photodiodes. It is also used to check whether there is a coin jam in the slot machine. , so that the coin dispenser can work according to the routine, to prevent abnormal work or someone stealing money due to other things being damaged. When all the double optical eyes work normally and the front and back programs can be aligned, the single chip microcomputer will send out control information to make the coin feeding motor work and make coins enter the coin channel. When entering, the coin feeding port will be closed. When the coin detection standard is inconsistent with the sample coin, the coin entrance will not be opened and the coin insertion will not succeed.

market positioning

Traditional laundry methods are time-consuming and inconvenient. With the improvement of the pace and quality of life, people in cities need an efficient, convenient and hygienic way of laundry more and more. Take the school as an example. It takes about 30 minutes to clean 5 kilograms of clothes at a time, and the ozone generator sterilizes them. The washing process is completely environment-friendly, achieving the real efficacy of high efficiency, cleanliness and sterilization, and the price is low. This kind of self-service washing machine has been popular in developed countries for a long time and is deeply loved by students.

Nowadays, schools are more inclined to humanized learning and living environment and excellent service. Adding this hardware configuration can improve the grade and taste of running a school, thus improving the visibility, influence and competitiveness of the school; The demand for self-help laundry is more prominent, which can give students more time to study. Coupled with the heat wave of China's internationalization, self-help laundry came into being, gradually forming a new consumption trend!

Functional characteristics

1, small size? Like ordinary household washing machines, the installation is simple.

2. Fully enclosed panel? The control panel of the washing machine is fully enclosed, and the card washing module exchanges data with the card reading module through electromagnetic waves.

3. Low failure rate? The washing machine and card washing adopt non-contact control technology, which has the functions of dustproof, waterproof, antimagnetic and antistatic, and can maintain good reading and writing performance in wet and dusty environment.

4. Simple operation? When the washing machine is in use, you don't need to make any choices after pressing the power switch. Just wave the washing card or coin in the induction area to start the washing machine to work normally.

5. According to the use characteristics of public washing machines, an ozone disinfection and sterilization device is added. Through the specially designed air pump and ozone generator, ozone bubbles are generated in the washing process and dissolved in water to form hydrogen peroxide, which achieves good disinfection and sterilization effect and prevents cross infection of bacteria.

The above is about coin-operated washing machine's principle, and I hope it will help you!
