Washing machinesThe washing machine from invention to now bas experienced more than a century, through the following stages of development:The world’s first washing machine is the United States in 1874 by Bill Blackstone successfully developed. Around 1910, a first horizontal shaft drum type electric washing machine, marking the housework automatic start. Nineteen twenties, the first vertical shaft stirring type washing machine to the United States of America trial-produce is successful, the washing machine, started the “vertical” and “horizontal” cent. The mid 50's, Japan’s Sanyo Company launched Dan Tongbo wheel type washing machine. Starts with the identification of a drum type, mixing type and the wave wheel three working modes. In 60, the Japanese launched with flings the dry barrel semi-automatic washing machine, and a large number of applications of plastic, so that the washing machine’s development into a new stage. In 70, the Japanese launched a wave wheel sets of barrels of fully automatic washing machine, began with “automatic” washing machine concept. In the late 70, the Japanese launched a microcomputer controlled full automatic washing machine. Completed by the mechanical and electric program control computer control transition, started the computer control era. Then, the washing machine in the developed countries have entered the period of saturation, while in Asia Pacific developing countries began to enter the period of popularization. The late 80's, “fuzzy control washing machine” began to appear, to achieve the home electric appliance control method on the high automation. “White goods” concept. In 90’s, with the development of inverter technology, Japan launched the first of up motor direct driven washing machine washing machine driving mode, realized the revolution.The washing machine will be of high reliability，perfect function, water saving and power saving, time saving and noise reduction of specifications varieties diversification for the direction of development.The reason why a washing machine like this can wash and get the water out of the clothes at the same time is because it has a double layer drum. When washing and rinsing, the pulsator spins and makes the water swirl... To get the water out of the clothes, the inner wall of the drum spins and the water goes through the holes.These days, the “centrifugal force washing machines” are quite popular. This type of machine does not use a pulsator. Instead, the inner wall spins really quickly. When the drum spins, the dirty clothes get stuck to the wall. The water and detergent also try to escape through the holes of the wall but before they do so, they are forced to escape through the clothes. When this happens, the power of the water and detergent removes the dirt form the clothes. Another good thing about this type of machine is that clothes don’t get tangled up so you don’t have to worry about your clothes getting ripped or damaged.Next, let’s look at some different types of washing machines!Many of you probably think that the water inside washing machines goes round and round. Actually, different washing machines make water flow in different ways.Whirlpool type:This type of washing machine uses a pulsator to force the water to move like a whirlpool inside the Drum. The spinning water forces the dirt out form the clothes inside the machine. Some of the newer models of this type also make the whirlpool move up and down to make it clean clothes even better!Agitator stirring type:This type of washing machine has something that looks like a propeller at the bottom of the tub. This Propeller spins around and stirs the water. The water then forces the dirt out from the clothes in the machine. The good thing about this type of machine is that clothes do not get tangled up and clothes get evenly washed.Drum type:This type of machine has a drum with many holes in it. There are also protrusions bumps on the wall of the drum. As the drum turns, the clothes are picked up by the protrusions. When the clothes fall down from the top of the drum through the water, the movement removes dirt from the clothes.Centrifugal force type:As we have said before, the spinning drum pushes the water and detergent out through the wall of the inner drum. The power that comes from spinning the drum is called centrifugal force, which is where the name comes from. The water is forced through the clothes and then the holes in the inner wall. After one cycle, the water is recycled back into the tank and the process starts again. This cycle is what cleans the clothes!In Japan, people first started using machines in 1930. But then the price of a washing machine was so high that most average persons could not buy one for their homes. Looking back now, there was something strange and funny on some of the first versions of the washing machine .The machine had two rollers that were used to sandwich each shirt and other clothes to squeeze the water out of them. The rol。
