In order to understand just how far dishwashers have come along, one has to take a trip back to when the first records of dishwashing devices were made known. The time was around 1850 when inventor Joel Houghton was able to patent his hand-powered device. Many people today can scarcely imagine having to actually hand propel their dishwasher yet this was an improvement to the old fashioned methods that had been used prior to the creation. Although this early dishwasher is now seen as slow and laborious, it was a huge step in the right direction of getting away from manual dishwashing.
It would be more than 30 years before another hand propelled dishwasher could come onto the scene and another seven years before it would be officially unveiled. Although this particular model did not have permanent plumbing, it was the result of inventor Josephine Cochrane's desire to have servants stop chipping the china. The first permanent plumbing models came along during 1924. Inventor William Livens created a small dishwasher with a rotating sprayer, wire rack inside and a front door. Although only designed for use in the home, it did not have an electronic drying feature, which was not incorporated into dishwashers until 1940.
By the 1970's dishwashers were like a household word and had become commonplace in the United States with most homes having one. From these original hand-moved units, the dishwasher designs were developed with capacities to include standard place settings for dishes and plates of regular sizes to fit properly into the cleaning compartment of the dishwasher. Likewise, standards were developed for dishwashers that are installed into a kitchen cabinet. These standards were devised so that the European hole should be a minimum 86 centimeters and the US equivalent is 34 inches in height for the opening.
From the original settings, features and sizes, dishwashers have come a long way to the deluxe features available today. Many models have drop-down front panels, several pull-out racks with baskets for silverware and small items, constructions of varying materials such as plastic and stainless steel, high energy efficiency ratings to save electricity and water, automatic hard food disposal units and built-in water softeners. With additional features on some models such as low noise, the modern dishwashers are designed with virtually every consideration in mind. Portability for those who need to have a dishwasher in a special space to dishwashers that can be hooked up in the sink, dishwashers started out very rudimentary but have continued to develop.
