A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating .
BEE Star Label is a program run by the Indian government's Bureau of Energy Efficiency under Ministry of Power that promotes energy efficiency. The program provides information on the energy consumption of products and devices using different standardized methods. The program for rating electrical appliances started in May, 2006.
A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...
Refrigerator, toaster, kettle, microwave, blender A home appliance , also referred to as a domestic appliance , an electric appliance or a household appliance , [ 1 ] is a machine which assists in household functions [ 2 ] such as cooking , cleaning and food preservation .
A microwave oven uses dielectric heating to cook food.. Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
Small appliances in a kitchen: a food processor, a waffle iron, a coffee maker, and an electric kettle Glowing filaments of a modern 2-slice toaster. A small domestic appliance, also known as a small electric appliance or minor appliance or simply a small appliance, small domestic or small electric, [1] is a portable or semi-portable machine, generally used on table-tops, counter-tops or other ...
Convection ovens are built with a fan placed in the back of the oven. When you turn on the convection setting, the fan blows warm air all around the inside of the oven, promoting rapid and even ...
The modern magnetron is a fairly efficient device. In a microwave oven, for instance, a 1.1-kilowatt input will generally create about 700 watts of microwave power, an efficiency of around 65%. (The high-voltage and the properties of the cathode determine the power of a magnetron.)
