What is a cooker hood? Structure and working principle of the cooker hood

The cooker hood not only effectively removes food odors but also enhances the interior beauty of the kitchen. Let’s read more about what a cooker hood is. Structure and working principle of the cooker hood through the information below!

1. What is a cooker hood? Structure and working principle of the cooker hood

The cooker hood is a device capable of removing food odors during the cooking process, minimizing the appearance of fishy smells in the kitchen space. The structure and working principle of the cooker hood are not too complicated. As follows:

2. Structure of the cooker hood

The cooker hood consists of 4 main parts:

  • Body: The outer shell is made of a metal compound with electrostatic paint, which is durable and contributes to the product’s aesthetics.
  • Fan motor: As the main part inside the cooker hood, there are usually two forms: a single (or double) turbine and a single fan.
  • The circuit boards on the control panel: The system that takes care of the functions on the machine and helps the user control the cooker hood. For example, when the filter needs cleaning, the smoke sensor system and the warning system.
  • Grease filter: A part made of aluminum to prevent rust and has the function of filtering grease smell. In addition, the cooker hood also has a filter element such as activated carbon that contributes to eliminating odors during the cooking process.


3. Working principle of the cooker hood

When power is supplied to the cooker hood, the internal fan motor system will suck the air, including smoke, grease, fishy odors, and gas, out of the cooking area by a pipe mounted on the ceiling or wall. During that process, the grease filter will do the job of absorbing the smell of grease, and there may be additional activated carbon that has the function of removing fishy odors.

For some cooker hoods, if there is no pipe, the air after being sucked will pass through the filter and then be treated and filtered before returning clean air to the kitchen space.

4. Types of cooker hoods

Here are some types of cooker hoods that you can find in the market such as:

4.1 Cabinet cooker hood

The under-cabinet cooker hood is a type of machine recessed into the kitchen cabinet, so it has a compact design and a delicate look. The common size of this machine is usually 60 – 70cm, has low noise, and does not cause discomfort to the user.

Moreover, the material of the cabinet cooker hood is usually made of high-quality stainless steel, which is not rusty and always shiny and resistant to fingerprints. For small kitchen spaces such as in apartments and dormitories, a built-in cooker hood is one of the ideal cooker hood choices.


4.2 Wall mounted cooker hood (wall mounted)

The wall-mounted range cooker hood is a model designed like a TV screen mounted on the wall, so it is also called a wall-mounted range cooker hood. Unique design, with high aesthetics such as tilting screen, curved glass to flat glass, the shape of the vacuum cleaner can be T-shaped, L-shaped or conical, etc., to create a highlight in the kitchen space.

The wall-mounted range cooker hood works based on suction. It pushes through the air duct to remove odors during the cooking process. In particular, this type of machine can absorb odors on a wide range and far from the cooker hood. It can even be fitted with an activated carbon deodorizing system to treat the gas before it is discharged into the environment.


4.3 Island cooker hood

The island cooker hood is a machine with a 2-way suction-reverse mechanism and is installed independently and hung from the ceiling in the middle of the kitchen. Most of these machines absorb odors directly through activated carbon – which is built into the machine’s internals.

Due to its characteristic design and rather large size, the island cooker hood is suitable for installation in large kitchen spaces, bar kitchens, and European-style kitchens.


4.4 Under-table cooker hood

The under-table cooker hood is a model installed under the kitchen table and can be controlled to raise – lower depending on users’ needs. The under-table cooker hood is similar to the above cooker hoods such as absorbing fishy odors, toxic fumes (such as CO2 and N2), and heat from the cooking process.


5. Benefits of a cooker hood

As we shared about the basic information above, the cooker hood is considered an indispensable interior in the kitchen space that you are worth considering:

5.1 Eliminate food blindness and contribute to clean air

During the cooking process, the appearance of many odors such as fishy smell from seafood, fried oil smell, burnt smell, … and even moldy smell from food will make the cook feel uncomfortable. Moreover, they also tend to stick to kitchen items, creating conditions for mold and bacteria to grow. Therefore, a cooker hood can help you prevent these phenomena from happening in the kitchen space.

5.2 Contributing to optimal health protection for the family

Using gas stoves often produces NO2 gas that is harmful to health, while the cooker hood is capable of sucking and handling this gas to contribute to better health protection for your family.

5.3 Adding a modern part, creating a highlight for the kitchen

Each type of cooker hood has its own advantages in terms of design and product material. This has made the kitchen space more modern and sophisticated and created the highlight that the cooker hood brings.
