Why do you have to open the window when you turn on the range hood in the kitchen to cook? What are

When cooking in the kitchen, the range hood is usually turned on.

to prevent the spread of oil fumes. However, when cooking, do you want to open the window? Because some people say turn on the range hood while cooking.

There is no need to open the window, while others say that the window needs to be opened when the range hood is turned on.

After cooking and turning on the range hood, it is best not to close the windows! Try to leave a seam. Why don't you close the window after you turn on the range hood.

The main purpose of not closing the window is to achieve two purposes: not to affect the smoke exhaust effect. After closing the window, the kitchen is a relatively closed environment, and the air cannot be convection, which can easily lead to the idleness of the range hood, which not only consumes electricity, but also affects the smoke exhaust effect; Opening a gap to allow outdoor air to flow in and form a negative pressure helps to increase the exhaust volume of the range hood and better and quickly discharge the oil smoke.

Comfortable and safe. When cooking, you have to be in a high temperature environment.

Middle. If you don't open the window to breathe, the space is too closed and will give people a feeling of suffocation. For a long time, it was uncomfortable! In addition, cooking is basically gas nowadays. If you don't pay attention in a closed environment, it is easy to form a safety hazard.

Therefore, when cooking in the kitchen on weekdays, it is best not to close the doors and windows! Leave a little gap in the timing of ventilation and convection to ensure the safety and comfort of the kitchen.

What else should you pay attention to when using the kitchen every day: When you are not cooking in the kitchen, you can open the windows appropriately to allow air convection. The residual oil smoke and peculiar smell generated by cooking are discharged, so that the air is fresh and the environment is comfortable; Allow unburned gases to diffuse and avoid build-up and hidden dangers.

Do not turn off the range hood immediately after frying. Let the range hood stay for 2-3 minutes, completely suck off the indoor range hood, reduce the adhesion of the range hood, and maintain hygiene in the future. Clean the range hood in a timely manner.

Clean the ventilator regularly and keep it clean and tidy; Avoid excessive oil contamination, which can affect the smoking ability of the range hood.

I think it's best to open the window when turning on the range hood in the kitchen for cooking, so that the air can be discharged as soon as possible and the life of the range hood will increase; If it is not turned on, it will prolong the use time of the range hood, affect the service life of the range hood, and the impact on the body is also very great if it is in the state of oil smoke for a long time.

Because the kitchen cooks, it is inevitable that the temperature is high, and opening the window can allow air circulation and be more comfortable. If you don't open it, it is easy to consume electricity and suffocate it. Because the window is closed, the air cannot be convection, which is easy to cause the range hood to idle; And if the air is not circulated, people are stuffy.

This is because it can be better ventilated, avoid damage and have no taste; If you don't open it, there are no obvious consequences, but it's more troublesome to clean up.

Turn on the hood with the door closed, not the window. When using a range hood, if the kitchen door and window are opened, a convection flow between the air will be formed, which will cause the cooking fumes to run around, and it is difficult for the range hood to suck all the fumes clean. If all the doors and windows are closed, the kitchen area can easily form a negative pressure area, and the range hood will not be able to smoke normally.

Therefore, the scientific approach is to close the kitchen door and open the kitchen window, so as to keep the air in the kitchen flowing normally, so that the range hood can suck the kitchen fumes as clean as possible. Loose oranges

Precautions for the use of range hoods:

1. The range hood should use a reliable grounding socket, and do not connect the ground wire to the gas pipe, water pipe, lightning rod and ** wire.

2. If there is loud noise and weak suction during use, please clean the range hood regularly.

3. Do not use hard objects to clean the surface of the range hood, please use neutral detergent to clean the range hood, and pay attention to the control part of the front panel to avoid water ingress when cleaning the machine.

4. When cleaning the range hood, the power must be unplugged.

5. The surrounding environment should avoid air convection caused by excessive opening or closing of doors and windows, which will affect the smoke exhaust effect.

6. The exhaust gas discharged is not allowed to be discharged into the hot flue.

When cooking at home, if the range hood has been turned on, do not open the window, which will allow the smoke to continue to run into the house, and close the window when using the range hood.

Of course, it is good to open the window, because oil smoke is harmful to the body, so it is a good choice to have a good ventilation.

A: It's good to open the window. When cooking, the range hood is turned on to exhaust the smoke, and the heat generated during cooking, opening the window can better assist in the smoke exhaust and heat dissipation.

It's better to keep the windows closed, so that the oil can be drained away and the wind won't affect it.

When people decorate their kitchens, they will equip the kitchen with a range hood, so that when they are cooking, they will not be troubled by oil smoke. But after many people turn on the range hood, some choose to leave the windows open, and some choose to close the windows. The choice should be made on a case-by-case basis.

If you are in a relatively closed environment, you should open the window, if the position of the window and the range hood are relatively close, then you should close the window at this time. <>

In a relatively closed environment, the range hood cannot completely absorb the oil smoke, and it will be filled with some oil smoke in the air. It will be very choking, and it will also affect human health, plus the kitchen itself is very airtight, and the air circulation is not particularly good. It is easy to have trouble breathing, so you should open the window at this time.

In the summer, the temperature itself is relatively high, and it is not possible to install air conditioning in the kitchen. <>

In this way, when people are cooking, the temperature is relatively high, and heat stroke is likely to occur. At this time, the windows should also be opened appropriately. However, the area of the kitchen is relatively large, not particularly airtight, and the oil absorption rate of the range hood is particularly strong, so in this case, the windows should be closed.

If the location of the window is relatively close to the range hood, the window should also be closed. <>

If the window is opened, the oil smoke generated will not be efficiently sucked up by the range hood, and may blow out the stove fire, which is also particularly dangerous. The weather is not particularly good, and it is windy and rainy, in this case, you should not open the windows when cooking. Otherwise, the wind and rain will be too strong, and the fire will be extinguished.

Not only can it not effectively remove oil smoke, but it will affect normal cooking. However, when closing the windows, it is not necessary to close them all, you can leave some gaps appropriately, as long as the air can flow in small amounts, it will not affect the effect of smoke exhaust.

When cooking, it is best to turn on the hood with the window open a little bit. Because the window is opened too much to accelerate the air circulation in the kitchen, the range hood is not effective in absorbing oil smoke, and opening it a little can balance the indoor and outdoor air pressure.

Keep the windows closed. You can also suck the fumes away, otherwise it may directly enter your mouth and affect your respiratory tract. The range hood has a new mode of self-modeling.

It should be closed, because closing the window can prevent harmful substances from polluting the outside environment, and it can also assist the range hood to work, otherwise the smoke will spread from the window to the outside.

I think the windows should be left open, because then all the fumes can escape. It will not affect the house, resulting in the smell in the house.

I think it's best to open the window when turning on the hood when cooking; This keeps the oil absorbed, prevents some messing around, and keeps the kitchen clean.

When the window should be closed and the range hood is turned on, he will follow the direction of the range hood, and if the window is open, it may not work very well.

I think it's because the windows are open, because although the range hood can absorb oil smoke, it is still necessary to keep the kitchen ventilated.

Range hoods are an electrical appliance that many people can't do without when cooking. When cooking, in order to reduce the absorption of oil smoke, it is necessary to turn on the range hood. After turning on the hood, it is okay if the window is not opened.

But generally speaking, opening the window is more conducive to dissipating the fumes, so when turning on the range hood, it is okay to open and close the window.

Turn on the hood. First of all, you can close the window。Whether or not to open the window will not affect the working of the range hood, and the window can be closed when the range hood is turned on.

Especially in the cold winter, there is no need to keep the windows open all the time to dispel the fumes; Secondly, the windows can be opened. When turning on the range hood for cooking, you can also open the window, which is more conducive to air circulation and can also reduce the concentration of oil smoke, especially when cooking in summer, it is very hot, it is best to open the window; Finally, it depends on the actual situation. When using the range hood, whether to open the window has no effect on the function of the range hood, whether to open the window mainly depends on your own needs, if it is hot, open it.

Turn it off if it's cold. <>

1. Close the windows. Whether to close the window has little impact on the range hood, if we feel that the outside noise is too loud when cooking, or the temperature is relatively low in winter, we should close the window. After all, the range hood is enough to suck in the cooking fumes. <>

Second, the windows are open. When cooking, you can also leave the window open. If it is a hot summer, in order to ventilate and reduce the odor in the kitchen, you can open the window when cooking.

This is really good for air circulation and will also reduce the emission of oil smoke. <>

3. Decide according to the actual situation. When cooking, whether or not you need to leave the windows open is determined by our actual situation. Whether the windows are open or closed has little effect on the hood.

Therefore, it is okay to choose to leave the windows open or closed. There are no requirements for this.

This time you can. Because the power of the range hood is particularly large now, the range hood can also go out with the window closed at this time.

Yes, because the function of the range hood is very powerful now, and it can absorb all the oil smoke in the house.

Of course, if the power of the range hood is very high, it can perfectly suck away all the fumes without any impact on the kitchen.

It depends on the actual situation of your home: for example, this is an open kitchen, and if you open the window, it will create air convection with the outside, which is the airflow, so it is better not to open it. In the case of good sealing, your home often has a range hood open, and it is difficult to enter a door, this situation occurs because the smoke range hood and range hood accidentally form a negative pressure in the air from indoor to outdoor, and the outdoor is positive pressure, so the indoor air pressure is lower than the outdoor, and it is within the range of indoor and outdoor air pressure, so it is difficult to enter the door, so it points to the open window, just to balance the pressure inside and outside.

<> addition, if this situation does not open a small window, any brand and form of fog machine smoking effect can be greatly discounted. Although you want to know, the range hood will suck up the fume, but it will not suck up all the fumes, there will be a small amount of fumes in order to make the fumes spread faster and suck away many people too late, so the windows or doors will be opened all, this practice is often counterproductive, the wind blows into the kitchen, and the fumes in the kitchen are everywhere, which will also affect the work of the range hood, and the fumes cannot be taken out normally. Nowadays, many friends will close the doors and windows, worrying that the kitchen fumes will float outside, and then cry the baby next door, or run to other parts of the room, this practice is not very correct, because the normal working range hood needs air convection, otherwise it will not be in danger of fumes, it is likely to inhale smoke, and more and more fumes will be produced when cooking, and then they will begin to doubt life.

Because the whole kitchen is closed, the range hood will take away a lot of air when cooking, you can't get fresh air, it's easy to get dizzy when cooking in the kitchen, and you also need some oxygen flame, the open kitchen range hood will only have a negative pressure, the smell of the sewer will be strong, suck out the range hood, it will be a scene that none of us can accept. So what do we do? In fact, it is very simple, with the progress of practice, all doors and windows can not be fully opened, doors and windows are closed, remember to open a small window when cooking, so that the air in the kitchen can form a convection, the indoor air pressure can be balanced, the range hood will work normally, the pollution in the kitchen will be reduced a lot, so if you suspect that the machine at home is not good, so you might as well see that you are not using the range hood correctly.

In addition, for the daily maintenance of the range hood, we should also pay attention to the fact that it is best to install the range hood on the upper part of the gas burner, with a height of not less than 650mm, remember to install the oil suction port on the special socket, there must be grounding, use the range hood, open the range hood 1 minute in advance, so that it is easier to absorb the range hood, clean the range hood regularly, unplug the power supply before cleaning, cut off the power supply, and pour out the oil storage box of the range hood to prevent excessive benefits.

It must have been turned on, because the hood is not able to absorb all the fumes and can be discharged through the window.
