下面为大家整理一篇优秀的essay代写范文- The application of fully automatic washing machine，供大家参考学习，这篇论文讨论了全自动洗衣机的运用。智能化电器的多样性，如洗衣机的形式和功能也是多样化，给人们带来方便，节省在洗衣上的精力。对于全自动洗衣机的核心控制系统部件，PLC控制技术的引用，给洗衣机智能化带来巨大的优化，使其运行更加稳定，功能更加完善。

The diversity of intelligent electrical appliances, such as the forms and functions of washing machines are also diversified, bringing convenience to people and saving energy on laundry. For the core control system components of fully automatic washing machine, the introduction of PLC control technology brings great optimization to the intelligence of washing machine, making its operation more stable and function more perfect.

Based on the development of domestic PLC, touch screen, inverter and other technologies, the trend of home appliances to automation. Washing machine is used as one of several common everybody to use electric appliance, by half automation develops toward full automation step by step. PLC technology has high reliability, low energy consumption, strong adaptability, fast running speed, long life and other characteristics, combined with the sensor, the configuration software control, inverter and other technology design of fully automatic washing machine will bring people to the use of different feeling, fully automatic washing machine will replace semi-automatic washing machine washing waste water, electricity, man-machine interface unfriendly, prone to failure, the noise big defects.

In ancient times, people basically washed their clothes by beating them with wooden sticks or rubbing them with their hands. Why? For as long as it is an object is made up of certain substances, and material it is made up of molecules, there is gap between molecules, so the stain was on the clothes is really exists in between molecules on clothing or clothing within the pores, while the ancient clothing in tow or artificial + machine woven where, so the washing agent with simple knock, under the dual role of besmirch can become detached from the clothing, in the water and then taken away. And the working principle of fully automatic washing machine is on such a basis, a series of needs to be completed by human to the machine to operate, so that the machine can fully control the process of laundry action. Fully automatic washing machine is mainly completed by four steps.

The water inflow is controlled by the washing machine itself. When the washing machine receives an indication that it needs water, the water supply system is activated. At this time, the inlet pipe connected to the washing machine will start to supply water to the washing machine bucket until the set amount of water is reached. Then the next step is to replace the artificial water supply and save a lot of labor and trouble.

After the start of washing, cleaning agent and clothes will start to contact with a large area through the action of water in the high-speed rotating bucket, resulting in mechanical action such as drainage, erosion and the wetting and dispersing action of detergent, pulling dirt into the water. Under the high speed washing drum rotating, the washing drum will produce a rotating vortex. Under the action of eddy current, the clothes and detergent begin to make spiral forward and reverse rotation, start to rub with the washing water in contact with the bucket and the wall of the bucket, and then keep repeating this process until the set strength and time.

Fully automatic washing machine drainage principle is actually very similar to the water principle, are in the washing machine issued drainage instructions after the start of the drainage system. When the drainage system is activated, the filtered sewage begins to drain through the drainage pipes of the system until the tank is empty.

During dehydration, high speed rotation will occur, and the clothes will be screwed together. Under the action of high speed rotation, the wrung water will fly to the wall of the barrel. At this time, the holes of the inner and outer barrels will be opened, and the water will slowly drain out of the barrel like drainage.

The completion of the above four steps is self-controlled, precisely because of its full automaticity, there are also some deficiencies in some aspects. For example, the power of laundry cannot be controlled accurately, there are errors in the grasp of the amount of laundry water, facing different materials of clothing is a routine set of procedures, so that many special materials of clothing can not be cleaned by fully automatic washing machine, and so on.

For washing machines in such a complex environment, the selection of control system requirements are very high. PLC control system, is for mechanical work complex environment, can adapt to its environment, and achieve the goal of the control system, has higher reliability, and environmental adaptability. In its PLC hardware design, its circuit structure and the manufacture technology have used the related optimization design and processing. The photoelectric isolation technique is used effectively in the circuit of both the input end and the output end of the electric energy system. With more accurate digital filtering; Electromagnetic shielding is used inside the system to prevent interference from external or electromagnetic radiation in the system. The more advanced power supply circuit in the market is used to prevent the electrical interference signals flowing in from the power supply circuit. The use of scientific and effective circuit procedures, the module can be implemented online plug and plug operations, debugging will not affect the normal operation of the machine. Control, timing, counting.

Washing machine is the indispensable civil electric appliance in family life. For the complex environment, choose to use PLC control system, maximize the reliability of system operation, to achieve effective cleaning, long-term use. Bring the greatest convenience to family life and save time spent washing clothes.
