Some people consider dishwasher as the numero uno reason for the liberation of the modern women. Some others give this esteemed position to the washing machine. Either way, these machines have been a real help for women of the world. Before the arrival of these machines, women used to spent innumerable hours doing these tedious and repetitive jobs. In many households, the kids were in charge of doing dishes after every meal. Occasionally, there were fights between the kids over getting the responsibility to do dishes way too many times or not. And they used to do the dishes manually! Only with their hands, water and detergent! If you say this to the kids of the present day, they may not even understand the situation correctly. Many of these spoiled brats have never seen any person doing dishes with their hands alone!
Dishwashers were first created towards the end of the 19th century. As women were traditionally responsible for this tedious job, a woman was behind the creation of this useful tool as well. Ironically, Josehine Cochrane, its creator was a rich lady and never did any dishes in her life. She got pissed off with her servants for damaging her expensive china! Hence the device was created to save her china. Any way, this tool has become a time saver for a large number of the US and European population who uses them regularly. Even if this device was created a century earlier, the sales of the dishwashers picked up towards the last quarter of the 20th century only.
In its basic form, a dish washer cleans the dishes through the application of hot water containing detergent on the soiled dishes. But the dishwashers of the present day are a lot more complicated than their predecessors. They have many more fancy features than the old wash, rinse and clean machines.
Now, some brands of dishwashers use water at a much higher temperature than older models and thus the pre-rinsing of the dishes are no more necessary. This is helpful in many ways as the duration of the wash cycle is reduced significantly.
There are certain dishwasher models with the ability to break down and remove food particles along with water. This way, the chances of food particles getting stuck on the dishes again is reduced a lot.
Some people have been complaining about the loud noise created by the dishwasher. Now, there are certain models with better insulation and thus operating at a much lower noise level. In addition to this, there are certain new dishwasher design changes like directing the water better at the dishes so as to reduce the noise levels even further.
Certain newer generation dishwashers have soil sensor technology incorporated so as to keep on constantly measuring the amount of dirt in the water. They will increase or decrease the duration of the wash cycle based on this information. This way, the dishwasher will be operating as per the needs of the particular dishes only. Thus, you are saving on your electric and water bills!
