To solve this problem, we also need to start with the analysis of smoke exhaust pipes. In China's residential areas, there are generally two types of flues, the main flue runs through the whole building and has been designed by developers for a long time; The secondary flue is relatively independent and "hidden" on the ceiling or wall of the kitchen according to the different kitchen design of each household. In theory, the lampblack in the ordinary household will first go to the secondary flue, and then enter the main flue through the hole on the partition, which can ensure that the lampblack in each household is isolated.

但是裝修時(shí)不合理的布局使副煙道拉的過長(zhǎng)、使煙道內(nèi)部環(huán)境曲折復(fù)雜，屬于不合理的煙道設(shè)計(jì)，從一開始裝修規(guī)劃的時(shí)候就該避免。針對(duì)這一問題，用戶可以在排煙管道中加裝一個(gè)鼓風(fēng)機(jī)，以加強(qiáng)排煙的力度，不過鼓風(fēng)機(jī)與油煙機(jī)無法做到同時(shí)啟動(dòng)，需要手動(dòng)進(jìn)行開關(guān)。而面對(duì)公共煙道的油煙倒灌現(xiàn)象，解決方案就是在自家煙機(jī)的煙道口裝一個(gè)止回閥，可使防止倒煙的效果更好。煙機(jī)工作時(shí)會(huì)打開，不工作時(shí)會(huì)自動(dòng)會(huì)關(guān)閉，這樣一來公共煙道里的油煙就不會(huì)進(jìn)到自家的廚房。但在家庭裝修中，不少家庭可能忽視了煙道出風(fēng)口的位置和設(shè)計(jì)的失誤導(dǎo)致了煙道過長(zhǎng)，它們?cè)诩抑凶蠊沼页?，重要的是排煙受阻，油煙倒灌等現(xiàn)象，當(dāng)然出問題的可能性也大大增加，給生活帶來更多的不便。

However, the unreasonable layout during decoration makes the auxiliary flue too long and the internal environment of the flue tortuous and complicated. It is an unreasonable flue design, which should be avoided from the beginning of decoration planning. To solve this problem, the user can install a blower in the smoke exhaust pipe to strengthen the smoke exhaust. However, the blower and the range hood cannot be started at the same time and need to be switched on and off manually. The solution is to install a check valve at the outlet of the flue of your cigarette machine to prevent the backflow of oil smoke in the public flue. The smoke machine will open when it is working, and will automatically close when it is not working, so that the lampblack in the public flue will not enter the kitchen. However, in the family decoration, many families may have neglected the position and design error of the flue outlet, resulting in the flue being too long. They turn left and right at home. The important thing is that the smoke exhaust is blocked and the lampblack pours back. Of course, the possibility of problems is also greatly increased, bringing more inconvenience to life.

在初的設(shè)計(jì)中用戶設(shè)計(jì)導(dǎo)致廚房煙道過長(zhǎng)的主要原因是采用了開放式廚房的設(shè)計(jì)，因此在裝修時(shí)為了精致美觀起見，讓室內(nèi)設(shè)計(jì)師將灶臺(tái)設(shè)計(jì)到了原客廳靠墻的一面。這樣就會(huì)導(dǎo)致煙道有很多拐角、折彎，長(zhǎng)期使用當(dāng)然會(huì)積聚很多油煙殘留物，排煙自然就有問題了，那么遇到這種情況應(yīng)該怎們辦呢？

In the initial design, the main reason why the kitchen flue is too long due to the user design is that the design of the open kitchen is adopted. Therefore, in order to be exquisite and beautiful during the decoration, the interior designer has designed the kitchen to the wall side of the original living room. This will lead to many corners and bends in the flue. Of course, there will be a lot of oil smoke residues accumulated after long-term use, so there will be a problem in smoke exhaust. What should we do in this case?

要解決這一問題，我們還需要先從排煙管道入手分析。在我國(guó)的居民小區(qū)中，煙道一般有主副之分，主煙道貫穿整個(gè)樓體，是由開發(fā)商早就設(shè)計(jì)好的；副煙道是相對(duì)獨(dú)立的，根據(jù)每家戶廚房設(shè)計(jì)的不同而“潛藏”在廚房天花板上或墻壁內(nèi)。理論上來說，普通戶型的家里的油煙會(huì)先到副煙道里，然后再通過隔板上的孔進(jìn)入主煙道，這樣可保證每戶的油煙是隔離開來的。

However, pay attention to the regular replacement of the check valve. Generally, it needs to be replaced once every two years, and regular cleaning should be done, otherwise the check valve will lose its effect.

當(dāng)然還有其他的一些措施，例如購(gòu)買功率更大、吸力更大、無死角的油煙機(jī)可以很好的解決這一問題，但是也增加了油煙機(jī)的負(fù)擔(dān)，造成一定程度的浪費(fèi)。好了，煙道很長(zhǎng)不要緊，為了你設(shè)計(jì)的美觀做一些犧牲也是應(yīng)該的，現(xiàn)在你該知道怎么做了吧。

Of course, there are other measures, such as purchasing a range hood with higher power, greater suction and no dead angle, which can solve this problem well, but also increases the burden of the range hood and causes a certain degree of waste. Well, it doesn't matter that the flue is long. It's also right to make some sacrifices for the beauty of your design. Now you should know how to do it.
