Halogen oven

From Wikipedia, the free encyclopedia

A halogen oven, halogen convection oven, or halogen cooking pot is a type of oven that utilizes a halogen lamp as its heating element. It is used primarily for cooking. Halogen ovens are often noted for being more energy-efficient than a conventional oven due to their use of a halogen lamp[1][2][3] reducing the cooking time usually needed in a conventional oven, and for also producing healthier lower-fat preparations of food.[4] They tend to be comparable in size, portability, and price to toaster ovens.[2]

Design

A common halogen oven features a heating chamber consisting of a clear glass bowl with a removable glass lid to which the heating assembly is secured.[2][5] Inside the heating chamber, multi-level metal racks are used to elevate the contents during the cooking process.[2] Within the heating assembly are the halogen lamp, a fan,[5] and the controls for the oven which frequently include an automatic shut-off timer and a temperature control interface.[2][6] A handle is also commonly a part of the heating assembly allowing users to lift the lid off the unit. This also serves as a safety shut-off switch that turns off the unit if the lid is removed during operation. The glass bowl is positioned atop a stand for table-top use. The stand raises the bowl off the table-top and decreases the transfer of heat from the heating chamber to the surfaces that surround the oven. Handles are often incorporated into the stand to allow for users to move the unit, providing safety especially during or after operation.[2]

Operation

The halogen lamp generates waves of infrared light to heat the air within the heating chamber.[2] The fan then circulates this heated air throughout the chamber to evenly cook the contents of the bowl through convective heat transfer, or convection.[1][5]

Efficiency

Reports often claim halogen ovens have shorter cooking times than conventional ovens, with one report stating a figure of up to 40% faster,[2] but 20% faster on average.[4] Another report claims a halogen oven cooks food up to 60% faster than a conventional oven.[1] In terms of energy use, one source claims that a halogen oven uses about "half the electricity of a conventional oven and about the same as a microwave oven".[3]

Easy-Bake Oven

In an effort to comply with the Energy Independence and Security Act of 2007, Hasbro redesigned its Easy-Bake Oven to utilize a halogen lamp for the oven's heating element in place of its less efficient conventional incandescent heating element.[7]
