How does an oven work explanation?

Answer 1

It uses an electric element to generate heat.

Current flows through the wire in the center of the resistance element, where the electrical energy is turned into heat. The heat is conducted through the insulator that surrounds the resistance element, into the metal jacket, then to the surrounding air.

Electric ovens have a thermostat, which is used to control the temperature of the oven. When the temperature goes above the set point of the thermostat the element gets turned off. When it cools off, the element turns on again.

They usually have two elements, a baking element below and a broiling element above. The baking element mostly heats the air to provide a uniform temperature in the oven. The broiling element is used to radiatively cook, from the top.

Answer 2

The function of an electric oven is to provide thermal energy in an enclosed space. This heat that it supplies will bathe whatever is in the oven cavity at a temperature set by the user. Compared to the gas oven, which burns natural gas, propane or the like to provide heat, the electric oven has resistive heating elements in it. There are still some ovens that are wood fired, if you wish to extend the comparison. In any case, the heating elements will become very hot (according to the temperature set by the individual operating it), and they cycle on and off to maintain a set temperature. Note that the elements do not run at the set temperature, but are either "on" or "off" as determined by the electronic circuitry that controls that heating element. There is a thermocouple temperature sensor in the oven cavity, and it communicates with the control where the user inputs or selects an operating temperature. The user also selects a mode of operation for the oven. Electric ovens almost always have a pair of heating elements in them. The "main" one is in the bottom, but there is another element similar to it at the top. This provides a heat source above the items in the cavity, and if you guessed that it is used to broil or brown food items, you'd be correct. Some ovens have a small fan inside that circulates the hot air in the cavity to more evenly and efficiently cook the food, and these are the so-called convection ovens. When replacing a range, it is wise to at least consider these cooking marvels. Any appliance salesperson will be more than happy to step you through the advantages. Control circuits range from a simple "thermostatic" dial to fully automated electronic equipment complete with a microprocesser controlled panel to allow more flexibility in the use of the device. The oven can be set to "come on later" or to "cook and hold" food, depending on the sophistication of the unit. The ovens may also have a self-cleaning feature where the heating element runs wide open for a fixed period to "burn off" anything stuck inside on the surfaces of the oven cavity. Adjustable racks and the little light that comes on when the door is open are pretty much standard. Food items exposed to heat "cook" in the oven. Proteins are changed in food items, and chemical reactions occur in baked goods like breads, cakes, pies and cookies. The oven can be used for a wide variety of things from standard cooking chores to drying herbs and salt that got a bit damp and clumped in the package. The standard cautions apply, and a small fire extinguisher or at least a box of baking soda should be kept handy nearby for an "emergency" that might arise. Note that if there is a fire in the cavity, it might be best to leave the door shut. At least gloss over the manufacturer's instructions, particularly those related to safety. If you don't have them, it might be wise to look at the instructions for a similar unit just to refresh your memory as to the ins and outs. Lastly, it might be wise to master all the operational quirks. That way you can maximize your use of the appliance. Just when you think you're down with everything, you'll find another way to use this vital part of your kitchen. Bon bppétit.

Answer 3

A conventional oven has a heating source; electric ovens have metal heating elements, gas stoves have a pilot flame that turns up with the temperature to heat the oven.
