By definition, a dishwasher is a mechanical device that is used for cleaning dishes and cutlery. The act of manually washing dishes involves a lot of physical scrubbing and rinsing to remove the dirt, grease, and food remnants on the dishes. On the other hand, an automated dishwasher cleans the dishes by spraying hot water, that is generally of the temperature range 45°- 75°C. The temperature can be altered, based on the level of the delicacy on the dishes and glassware.

Workings of a dishwasher

The basic principle behind the mechanical device’s workings is automation of the physical act. A mixture of water at the set temperature is mixed with the detergent and pumped into one or more numbers of the spraying arms, blasting the dirty dishes. This step is called washing. Once the above step is complete, the water is drained. More hot water then fills the cistern to rinse the washed dishes. This is called the rinse cycle. After being rinsed, the dishes are dried using any one of the many drying methods. In most cases, a rinse-aid, which is a chemical–based substance, is used to reduce the surface tension of the warm water.

Types of dishwashers

Domestic dishwashers

These are designed for usage in a domestic household. Standard units that are installed in the kitchen cabinets have dimensions around 18 and 24 inches. These have countertops attached to them to easily fit into the kitchen. Domestic units come in standard and tall tub designs. The only difference between the two is the capacity. The tall tub units have 20% extra in comparison to the standard units.

Commercial dishwashers

These are specially designed to use in restaurants or hotels. Washing occurs with higher temperatures between 65 and 71°C. The large-scale cleanliness is achieved by using a booster heater or through a chemical sanitizer. Although dishwashers might not be an absolute necessity in the household, they have become a part and parcel of the lives here, in our country.
