The hood consists of a skirt positioned over this surface at a height that is comfortable for the average user. The skirt surrounds grease filters backed by a fan that sucks air into the unit. Fans may feature several speed options. Most fans have at least two speed settings, one designed for operation during cooking, and one that is much quieter to be used during meals. Some advanced models have an automatic fan feature that turns the fan on when temperatures get too high. This feature is a signal to the fan that steam or smoke might be present in the air and the fan should be operating. Range hoods can also feature automatic shut-off timer options. Under-cabinet hoods. A very common type of range hood is an under-cabinet hood, which is installed beneath a cabinet above a stovetop. These hoods generally require piping and tubing to exhaust fumes, smoke and gas outside of the building. Wall-chimney hoods. These hanging hoods attach to the ceiling or wall and then exhaust air outside.
A range hood is a mechanical installation designed to filter air of airborne particles related to cooking. These particles include airborne grease, combustion products, smoke, odors, heat and steam. They are also called extractor hoods or ventilation hoods, are used in kitchens to provide cooks with clean air, while also preventing greasy buildups from forming on walls and other surfaces. Types of Range Hoods Because domestic and commercial kitchens have varying layouts, there are a number of hood types for different situations and setups. Additionally, range hoods use different operating principles to filter kitchen air, with certain designs more suited to domestic over commercial uses, and vice versa. A typical range hood maintains a similar position directly above a cooking surface, most often the stove. Range hoods should be wide enough to cover this surface entirely.
The hot, moist, greasy effluent stream produced by cooking is suctioned in and exhausted outside, instead of letting it blow right in your face. Any chef who spends a significant amount of time in the kitchen environment will attest to the difference between cooking in comfort, and having to endure a steam bath for several hours. While were on the subject of comfortable cooking, it is worth noting that an overhead range hood provides additional lighting, right where you need it the most. One of the considerations for selecting a range hood should be the amount of light it provides, as well as the type of lighting - halogen, fluorescent, incandescent, or a combination. Keep in mind that the bulb wattage does not need to be high, since the hood will be much closer to the cooktop than the room lights. In addition to work lights, some high-end designer range hoods offer spectacular lighting effects, and some hoods also include warming lights.
It is easy to replace the hood but you should know which model and style to choose before replacing it. Basically range hoods are of two types. The ducted range hood draws the heat, smoke, fumes, odor and moisture from the cooking range and suck it up a vent and release it out side of the house. The ductless range hoods on the other hand filter out the odors from the air. The other components like smoke and fumes are just blown around the kitchen. They are not physically removed. Features-wise there is not much to choose from. They work on very simple system of using a fan to suck out the air away from the cooking area and filter it out through the duct or send it out of the house. What you need to look for is a system that works with little noise and provides sufficient lighting to allow you to cook with ease.
