If you want to change the position of the kitchen flue at home, how should you change it better?

The crossing is reserved by the developer when building a house, and its function is to discharge the kitchen fumes. Some owners don't know the location of the smoke crossing in their kitchen, so where is the flue in the kitchen? Can I change the position of the kitchen smoke outlet? Some owners also want to put tiles on the smoke crossing, so can the kitchen flue be directly put with tiles? Let's take a look with Bian Xiao.

1. Where is the kitchen flue?

The kitchen is where we cook, but every time we enter the kitchen, there is a smell of oil smoke in the kitchen, which is probably the smell of kitchen flue. First you need to know the location of the kitchen flue, so where is the kitchen flue?

The residential smoke exhaust pipe is a chimney installed in the kitchen and bathroom of the residence, which sends the smoke to the external space. It is a nonmetallic pipeline product, which is used to remove kitchen fume or polluted air in bathroom. Also known as residential exhaust duct, residential ventilation duct and residential smoke exhaust duct. The structural forms of residential exhaust ducts can be divided into four types: single-channel exhaust duct, mother-child exhaust duct, variable pressure exhaust duct and variable cross-section exhaust duct.

The single flue exhaust duct is the earliest vertical centralized smoke exhaust system in residential buildings. The structure of this exhaust duct is too simple, the air inlet has no parts to prevent the smoke from flowing backwards, and the air outlet of the hood has no windproof measures, so the phenomenon of smoke flowing backwards is very serious. At present, this kind of exhaust duct still exists in many old houses.

Of course, there is no auxiliary flue at the bottom of some high-rise residential buildings, only the main flue, and there will be main and auxiliary flue after the floor is high, which should be dealt with according to the actual situation.

2. Can the position of the kitchen smoke outlet be changed?

The kitchen smoke crossing is equivalent to the former chimney. Now there are few chimneys, but there will still be one. It just appeared in a different form, that is, it was replaced by a smoke machine. Many people want to change the position of the smoke outlet when installing the range hood, so can the position of the smoke outlet in the kitchen be changed?

1. Can the position of the smoke crossing be changed? Generally, smoke crossings cannot be changed, except for villas. The flue is not straight, but has partitions on each floor to prevent the oil smoke from downstairs from escaping into the kitchen upstairs. If the opening direction of the flue is changed, then this interlayer will not work, and the oil smoke may not be discharged, which may also lead to the oil smoke scurrying around. If the residents upstairs change the flue, it may lead to the blockage of the flue downstairs.

2. Is there a load-bearing wall flue that can be replaced? The flue of the load-bearing wall cannot be replaced. The load-bearing wall is the wall responsible for supporting the floor. Starting from the basement, each family's load-bearing wall supports the upstairs floor. In addition to the outdoor walls, there are several walls in the house to help support and ensure the firmness of the building, which cannot be changed at will.

Otherwise, there will be unexpected cracks in the upper floor or outdoor wall, and with the increase of cracks, the floor will slowly collapse; Even if it does not collapse, it will shorten its building life and accelerate the possibility of becoming a dangerous building. The principle is very simple, just like the original reinforced bar supporting the whole building to form a balanced state. When you disassemble and modify the support, the uniform stress will be broken, and it will deform, crack or even collapse after a long time.

3. Can the kitchen flue be directly tiled?

Because the kitchen fume is large, the walls are generally tiled, because it is more convenient to wipe the tiles. Even if there are oil stains attached to them, they will be cleaned with a rag dipped in some detergent.

However, due to the heat around the flue and serious water absorption, a big problem will be encountered when sticking tiles, that is, tiles will crack or even fall off before long.

Can the kitchen flue be directly tiled? Obviously, it is not possible, and it needs thickening treatment. Thicken the flue and build a brick wall around the flue with sand bricks. First, it can avoid the tiles falling off easily after a long time, and second, it can enhance the adhesion between the tiles and the flue.

At present, the operators of the original flue are mostly mineral wool boards, which are very thin, with high thermal conductivity and low adhesion. If the tile is attached to the surface, it will expand when heated and contract when cooled, and it will easily fall off.

There are also some ways to use the method of batch swing, which uses cement mortar to batch swing the surface, thicken the thickness of the flue surface and keep warm, but it may also cause delamination.
