Code for installation of kitchen flue

Are you familiar with the public flue in life? In fact, the public flue refers to the vertical flue used by the kitchen to discharge the oil smoke and cooking waste gas in the house. When decorating the kitchen, we will install the kitchen flue, but many people don't know the installation specifications of the kitchen flue. So what is the installation specification of kitchen flue, and what are the cleaning methods of kitchen flue? Let's give you a detailed introduction!

A, kitchen flue installation specification

1, the auxiliary flue must be kept.

Every kitchen has a flue, and at the same time, the flue also has the main and auxiliary points. The main flue runs through the whole building and the auxiliary flue is relatively independent. Generally, the lampblack at home will go to the auxiliary flue first, and then enter the main flue through the hole in the partition, so as to ensure that the lampblack of every household is isolated. However, if the auxiliary flue is directly connected with the main flue, it will lead to the phenomenon of backward smoke or cross smoke due to too low pressure.

2, the details should be paid attention to in the construction

First of all, it is very important to choose the installation position of the range hood. The shorter the pipe, the better. Some owners will pull the pipe longer for the sake of beauty. After turning off the range hood in this way, there will be a lot of oil smoke in the pipeline that can't be discharged and then poured back indoors. In addition, in order not to destroy the original main and auxiliary flue, its opening direction cannot be changed at will, and it must be drilled in the auxiliary flue.

Pay attention to safety when smoking from the window.

In order to avoid the problem of smoke crosstalk, some owners gave up the original flue and directly opened holes in the windows to smoke. This is ok, but there are a few points to pay attention to.

First of all, before opening a hole in a window or wall, it must be approved by the property; Secondly, pay attention to safety issues. Generally, the end of the exhaust pipe is metal. If the hole is too small, the metal heat transfer may cause the glass to burst and hurt pedestrians, and the smoke exhaust pipe will lead out of the window, and the strong north wind blowing head-on will lead to the backflow of oil smoke. In this way, when the pipeline is extended, it can sink, and when it rains, it can also prevent rainwater from flowing into the pipeline and keep the windshield out.

Second, the kitchen flue cleaning method

If the kitchen flue is often not cleaned, it will leave oil stains and other substances in the range hood and flue. After a long time, oil stains will be formed, and the simple flue fume can not be cleaned, which will affect the use of range hoods and flues, and 80% of the reasons for the poor smoke flow are caused by poor smoke exhaust in the kitchen.

Generally speaking, the built-in filter screen of oil fume purifier is not cleaned for a long time, and the oil is blocked in the filter screen, resulting in flue blockage. Generally, high-pressure jet can be used to strengthen oil agent to treat flue oil pollution, so that the oil fume flow can be obviously improved.

A protective film is formed to prevent oil stains from remaining on the flue surface. The cleaning contents include the cleaning of the lampshade, exhaust port, exhaust port and flue on the surface of motor and cooker. The focus of flue cleaning is the flue whose exhaust port is connected with the hood and synchronized with the hood, and the interior of the parallel flue is thoroughly cleaned.

The above is the introduction of the installation specification of kitchen flue and the cleaning method of kitchen flue. Through the content of the article, everyone has a further understanding of the installation method and cleaning method of kitchen flue. You can refer to relevant technologies and construction files for reference. I hope it helps you.
