Dishwasher

Dishwasher is a mechanical device used in homes and commercial establishments for cleaning dishes and utensils. Dishwashers are a popular choice due to their efficiency and convenience, saving time and effort compared to manual dishwashing.

History

The first reports of a mechanical device for dishwashing dates back to the 1850s. However, the first practical dishwasher was invented by Josephine Cochrane in 1886. Cochrane's invention was a hand-operated mechanical dishwasher. She later founded the company that eventually became KitchenAid, a popular brand of dishwashers today.

Types of Dishwashers

There are several types of dishwashers available in the market today. These include:

• Built-in Dishwashers: These are the most common type of dishwasher, installed under the kitchen counter.
• Portable Dishwashers: These are standalone units that can be moved around the kitchen.
• Countertop Dishwashers: These are compact units that sit on the kitchen counter.
• Drawer Dishwashers: These are installed in a drawer-like fashion, allowing for washing smaller loads.

How Dishwashers Work

Dishwashers clean dishes by spraying hot water and detergent on the dishes. The water and detergent are then drained, and the dishes are dried using heat.

Environmental Impact

Dishwashers are generally more water-efficient than manual dishwashing. However, they do consume electricity, which can have an environmental impact depending on the source of the electricity.

Health Aspects

Dishwashers can help maintain hygiene in the kitchen by ensuring that dishes are cleaned thoroughly and consistently. However, some studies suggest that dishwashers may contribute to the development of allergies in children by reducing their exposure to microbes.
