What to do if the smoke exhaust hood has a bad odor

　　1、可以在煙(yan)(yan)道位(wei)置加裝一個的止逆閥(fa)(fa)，當油(you)煙(yan)(yan)經過止逆閥(fa)(fa)的時候，止逆閥(fa)(fa)可以讓油(you)煙(yan)(yan)直接(jie)朝，避免朝下流。的止逆閥(fa)(fa)不僅可以保(bao)護油(you)煙(yan)(yan)機，還可以有效防止煙(yan)(yan)道里(li)面(mian)(mian)的油(you)煙(yan)(yan)倒灌(guan)會(hui)油(you)煙(yan)(yan)機里(li)面(mian)(mian)和管道里(li)面(mian)(mian)，使得室內(nei)出現(xian)反味現(xian)象。

1. A high-quality check valve can be installed at the flue position. When the oil fume passes through the check valve, the check valve can allow the oil fume to flow directly upwards, avoiding flowing downwards. A high-quality check valve can not only protect the range hood, but also effectively prevent the backflow of oil fumes from the flue into the range hood and pipes, causing odor reflux indoors.

　　2、還可以在(zai)煙(yan)道口(kou)位置(zhi)直(zhi)接加裝一個密(mi)閉閥，在(zai)密(mi)閉閥和煙(yan)機(ji)閥的共(gong)同運(yun)行下，一般(ban)不是非常(chang)嚴重(zhong)的油煙(yan)都是無法倒灌回管道里面和油煙(yan)機(ji)里的。

2. A sealed valve can also be directly installed at the flue outlet. Under the joint operation of the sealed valve and the range hood valve, generally not very serious oil fumes cannot be poured back into the pipeline and range hood.

　　3、若排(pai)煙罩反味(wei)是因(yin)為排(pai)煙管破(po)裂、連(lian)(lian)接不(bu)良導致的，則(ze)可以將油煙機的排(pai)煙管更換(huan)成新的，或者是重新連(lian)(lian)接排(pai)煙管。

3. If the odor of the smoke exhaust hood is caused by the rupture or poor connection of the smoke exhaust pipe, the smoke exhaust pipe of the range hood can be replaced with a new one, or the smoke exhaust pipe can be reconnected.

　　4、若(ruo)排(pai)煙罩(zhao)反味是(shi)因為排(pai)煙管和公共(gong)煙道之間的(de)連接位(wei)置(zhi)出現了密封不嚴現象導致的(de)，則可(ke)以使用玻璃(li)膠或者(zhe)是(shi)透明膠等將縫隙位(wei)置(zhi)密封嚴實。

4. If the odor of the smoke exhaust hood is caused by poor sealing at the connection between the smoke exhaust pipe and the public flue, glass glue or transparent glue can be used to tightly seal the gap position.
