Bachelor griller

A bachelor griller, mini oven or mini kitchen is a countertop kitchen appliance about the size of a microwave oven but instead can grill, bake, broil or roast food. It generally incorporates one or two heating elements at the top and bottom of the appliance, has one or two hobs () on the cooktop, or a ceramic hotplate, and may incorporate a rotisserie.
It can be used to fry, bake and grill () foods. It is an alternative to reheating prepackaged meals in a microwave oven.
Modern bachelor grillers have controller knobs to control cooking temperatures. These are steadystates, a combination of a potentiometer and a thermostat, which ensure that the temperature stays stable.
History.
The expression is at least 100 years old, with early versions generally powered by gas. The expression derives from the stereotypical idea that a bachelor will not cook anything properly, if at all. There has never been a brand name for these appliances called "Bachelor"; it has just become common parlance in the United Kingdom.
George Orwell used a bachelor griller in 1935 while sharing a flat with Rayner Heppenstall in Bloomsbury, London.
