Infrawave+Oven

=My Device= skern toc



Purpose
The purpose of the infrawave oven is to transform electricity into infrared radiation in order to heat and cook food faster than a confection oven, but have the food crisper and a better quality than a microwave//.// It is also designed to be an efficient method of cooking food. All infrawave ovens are nearly 100% efficient because only the electrical infrared is directed at the food, and none of the energy is absorbed by the air.

Energy
Electricity is sent through the wire, and it is converted into infrawaves and visible light in a filament. The filament lights up like a lightbulb, and it sends the infrared raditation into the food. Because of the wave length of the infrawaves, there is no need for a medium between the filament and the food. The air cannot absorb the infrawaves, so the air around the food does not get hot. The food absorbing the infrared is how the food gets heated. The food then gets cooked from the outside in because the outside absorbs the infrawaves first, and the heat gradually transfers to the inside of the food. This slows down the cooking process, but it makes the outside of the food crisp, but the inside ia still hot, but softer. The filament converts the electricity into both visible light and infrared. Most of the energy is converted into infrared, but just enough is converted into visible light to cause the light to turn on and off as inrared is reflected into the food. The light will turn on and off periodically through the cooking process because in order to cook the food correctly, infrawaves can not be fired constanly. Each blast of infrared needs time to be absorbed into the food so the inside will be cooked as well as the outside. [|source]

Controls
There is a touch pad on the front of the oven. The touchpad is connected to a circuit board, and when you press down on a button two pieces of metal are connected, and electricity is sent to the light at a certain frequency. The control panel consists of many unique settings. There are buttons for specific foods which send signals to the oven to cook the food for a certain time and at a certain intensity.

Materials
The filament is essential to this device. It is made of metal, usually tungsten wire, and it is surrounded by a quartz tube. It is encased in the same manner as a standard lightbulb because the filament converts the electricity into visible light as well as infrared. This lightbulb set up is why a light turns on and off periodically during the cooking. There is gold on the outside of the quartz tube on the filament that reflects the infrared and directs it toward the food. [|source]

EM radiation is a scientific principles involved in the infrawave oven. The wavelength of the radiation is a key element in the ovens efficiency and speed. Infrared radiation is very close on the spectrum to visible light. The fact that they are this close on the spectrum allows the filament to convert electricity into visible light and infrared.

Design
The typical microwave oven is a stainless steel rectangular miniature oven, slightly bigger than a toaster. The front is a clear glass door that allows one to see inside the oven when the food is cooking. There is a metal rack inside the oven, like a standard oven, that you put the food on. There is a light on the top inside the oven that turns on and off periodically throughout the cooking process, allowing you to see the food as it cooks. There is a control panel on the front with specific settings to cook certain foods, but you can also type in your own cook time on the timer in the center.

Evolution
Although the infrawave oven is very efficient, it could be made more efficient in the future by making the filament able to convert all of the electricity into infrared raditation instead of wasting energy by converting it into light. The oven could also be made faster by increasing the amount of infrared that is reflected into the food.
