Oven, also known as oven, oven, baked oven, refers to the use of hot air cooking food a device, generally closed or semi-closed structure. Hot air heated in open form is called a barbecue. Ovens can also be used to refer to heat-gas treatment of high temperature devices.
In the West, ovens are the common equipment of traditional family kitchens, generally horizontal. In the central plains of China, it is traditionally used in catering trade rather than household, mostly vertical. China's ancient ovens are not widespread, possibly caused by insufficient fuel. Traditional ovens use wood and coal to burn. Modern ovens use more electrothermal or natural gas, and have an automatic thermostat system.
