The effectiveness of the air purifier largely depends on the correct use of it. And if with classic models everything is more or less clear, then how many people do not know how to use an inclined hood. In fact, both those and other varieties of the device work the same way. There are no significant differences in management, with the exception of the ability to use new functions.
A range hood is a very important appliance in the kitchen. It absorbs unwanted odors and fumes, which, in addition to irritating the sense of smell, openly harm the health of the cook. Hazardous compounds such as formaldehyde, benzopyrene, ammonia, acrolein, perylene, chrysene and others are released during cooking. And if the stove is gas, then the toxic cocktail additionally contains carbon monoxide, carbon dioxide, nitrogen and sulfur, radon, soot.
General rules for using hoods
How to use a cooker hood? There are 4 main rules:
- No need to wait until the kitchen is filled with caustic smoke and steam. The hood is switched on immediately, as soon as the cooking process is started, or a few minutes before. So she copes with her task as efficiently as possible.
- Increase power gradually. It is not recommended to turn on the device immediately at full power. This creates an additional load on the electric motor. To extend its service life, a soft start is carried out. Start at the lowest power and then adjust it to your needs.
- Turn off the appliance when the air is completely clean and fresh. After cooking, the hood is left to work for another 5-15 minutes. Firstly, steam is still coming from freshly cooked food. Secondly, particles of compounds and smells are carried throughout the room by a draft created by movement in the kitchen, open windows, doors. It takes time to completely clean the room.
- Do not cook under the hood using an open flame. Flaming and grilling over an open fire creates a fire hazard - grease deposits on the exhaust filter can easily ignite.
The operation of circulation, exhaust and combined hoods
There are two main types of devices.
- Bypass.
The device is connected by a sleeve to the ventilation duct. The air entering the duct is discharged outside the house.
- Circulating.
The polluted air is passed through the filters and returned to the room when it is cleaned. A carbon filter is required for operation.
Most modern hoods are combined and can work both in air intake and recirculation modes. The first is highly random (30–35% higher). It is recommended to use it when frying, cooking dishes with a large number of fumes (for example, stewing cabbage). The recirculation mode is considered universal and can be used both during cooking and to improve air exchange in the kitchen.
An extractor hood mounted above a gas stove must not be used in air circulation mode, since air currents can extinguish a fire. When using an inclined type of equipment, the fire hazard is less. But still, the possibility of enabling recirculation requires consultation with a gas service specialist.
How to use an inclined hood?
Inclined type hoods have many advantages over classic models:
- The modern device has high power and is characterized by quiet operation of the electric motor.
- Inclined hoods work on the principle of perimeter suction. Unlike conventional devices, which absorb pollution over the entire area of the working panel, in these models the air flow passes through narrow slots located around the perimeter. In this way, powerful vortex flows are created (Coanda effect). Contaminated air goes directly to the filter elements and does not disperse in the room.
How to use the inclined cooker hood:
- Turn on the device and select the desired mode.
- If you decide to use manual settings, select the minimum power.
- For large vapors, add power.
- After cooking, turn off the appliance (the residual stroke should work).
The inclined arrangement of the hood allows you to free 70% of the space above the stove. Such devices are small-sized, concise and absolutely not bulky. On some models, you can adjust the incline level to increase productivity.
Automatic operation
Inclined hoods are modern and functional. Sensors are built into the device that determine the level of humidity, the presence of smoke, steam. It also responds to fever.
You can not only adjust the traction and air circulation speed according to your needs, but also fully automate the air purification process. In other words, the hood automatically turns on as soon as you start cooking. The device selects the optimal power and other operating parameters in accordance with the degree of air pollution. When the room is completely clean, it goes into standby mode.
The program is activated in different models of hoods in different ways: "R", by pressing "+" and "-" together.
Interval ventilation
Another useful hood operation mode. When activated, the appliance will periodically turn on automatically and clean the air in the kitchen.
Many do not even suspect that even when nothing is being prepared, the room is filled with undesirable connections. In addition to the stove, detergents and cleaning products, furniture, especially new ones, are a source of air pollution.
Hood Care and Filter Change
As it becomes soiled, the efficiency of the hood decreases. Grease and soot clog filters and allow less air to pass through. It is very important to clean them in a timely manner and replace them.
How to care for the device?
- The external surfaces of the hood must be washed 1-2 times a week with a soft cloth using detergent for dishes. The use of abrasive products, caustic alkalis and acids is prohibited.
- Carbon filters are replaceable and must be replaced every 2–4 months.
- Grease filters are removed and washed with the use of fat dissolving agents about once every 2 months.
During the change of filters, the device must be de-energized by disconnecting it from the mains.
Do I need to turn on the hood while cooking?
Yes, if the automatic mode is not activated or for some reason the hood did not work.
Can doors and windows be opened during hood operation?
Doors are not necessary, but it is recommended to open the windows for ventilation (in vertical position). A moderate flow of air increases the efficiency of the hood. But it is important to eliminate the draft. He will carry all the smells and fumes throughout the apartment.
What is the residual stroke of the hood?
To remove residual contamination, modern devices after shutdown work in the residual stroke mode. That is, the fans automatically spin for a while, after which they completely stop. The residual stroke time can be manually adjusted by setting 5, 10 minutes or more.
Why is the hood making a lot of noise?
The most common causes of noise are loose sleeves, damaged joints, and air congestion.
Odor and smoke are not removed well, what could be the reason?
Ineffective hood operation may be due to improper positioning. Above the gas hob, it is placed at a height of 0.7–0.8 m, above the electric - 0.6–0.7 m. It is equally important that the dimensions of the appliance correspond to the dimensions of the hob, and the power - the area of the room.
If the air cleaner is a bypass type, it is worth checking the traction in the ventilation duct of the kitchen. Its clogging is one of the most common causes of smoke retention in the kitchen. It is possible that you just need to change or clean the filters. Also, a malfunction of the device cannot be ruled out. If replacing the filter does not help, it is best to call a specialist.
So, inclined hoods have improved functionality. You can use them in manual mode exactly the same as classic models. And you can turn on the automatic
