A kitchen extractor hood is an electrical device that is installed above the kitchen and is used to extract the stale air that is produced during cooking.

The extractor hood has a fan that draws in the air and directs it through a duct to the outside of the house or filters it and recirculates it into the environment.

Parts of a kitchen extractor hood

The parts of a kitchen range hood are described below:

the casing

The casing is the outer structure of the cooker hood. This part is designed to cover and protect the internal components of the hood.

The filters

The filters are the most important part of the kitchen extractor hood, since they are in charge of trapping the vapors, odors and smoke that are produced during the cooking of food.

The motor

The motor is the heart of the kitchen range hood. This component is the one that provides the necessary energy to operate the hood and create the necessary suction to eliminate the gases.

ventilation ducts

Now that you have knowledge about the components that make up this device, it is time to delve into how a kitchen extractor hood works.

A kitchen extractor hood works through a ventilation system that extracts contaminated air and expels it outside the house. This system consists of several components, including:

Grease filter: This filter is located in the lower part of the hood and its function is to collect the fat and solid particles produced during cooking. It is important to clean the filter regularly to prevent clogging and allow the hood to work efficiently.

Fan: The fan is the motor that moves air through the hood. It can be of different sizes and powers, depending on the size of the kitchen and the use that is given to the hood.

ventilation duct: The vent is the tube that connects the hood to the outside of the house. It is important that this duct is installed correctly and has the proper diameter to allow good air circulation.

Air vent: The air vent is the point in the house where the ventilation duct expels contaminated air. It is important that it is located in a suitable place, to prevent air from returning to the house.

What types of kitchen extractor hoods are there?

There are several types of kitchen range hoods, each with its own characteristics and advantages. Next, we briefly explain the most common ones:

Wall extractor hoods: They are installed directly on the wall and are very effective in removing smoke and odors.

Island Range Hoods: they are suspended from the ceiling and are used in kitchens with a central island.

Integrated extractor hoods: they are installed inside the kitchen furniture, which makes them less visible.

Decorative extractor hoods: In addition to being functional, they are also a decorative element in the kitchen.

What aspects to take into account when choosing a kitchen extractor hood?

If you are thinking of buying a kitchen extractor hood, there are several aspects that you should take into account beyond understanding how a kitchen extractor hood works, all of this in order to choose the best option for you:

Size: the hood must be large enough to cover the entire cooking area.

Extraction capacity: Extraction capacity is measured in cubic meters per hour (m3/h) and is important to ensure that the hood can effectively remove smoke and odors from the kitchen.

Noise level: The noise level is an important aspect to consider if you do not want the hood to be too loud.

Vent Type: You must choose if you want a hood that ventilates to the outside or that recirculates the air inside the kitchen.

Style and design: The style and design of the hood are important if you want it to integrate well with the style of your kitchen.

How do you use a kitchen range hood?

Using a kitchen extractor hood is very simple. Just turn on the power switch or button on the hood and adjust the fan speed according to your needs. Most range hoods have multiple speeds, from the lowest for everyday use to the highest for intense cooking situations.

It is important to remember that the hood must be turned on before you start cooking and must be kept on throughout the cooking process and for a few minutes afterwards, to ensure that all contaminated air is expelled to the outside.

How do you clean and maintain a kitchen range hood?

Regular cleaning and maintenance of the kitchen extractor hood are essential for its correct operation and to avoid obstructions in the ventilation duct. These are the basic steps for cleaning and maintaining the hood:

Clean the surface of the hood: The hood surface should be cleaned regularly with a damp cloth and mild detergent. Avoid using abrasive products that can damage the surface.

Clean the ventilation duct: The ventilation duct must be cleaned regularly, at least once a year, to avoid blockages and ensure good air circulation. You can do it yourself or hire a professional to do it.

Replace the activated carbon filter: If your range hood has an activated carbon filter, it should be replaced regularly, according to the manufacturer's instructions.
