1、 The installation method of smoke exhaust pipes should be correct. The owner is concerned about the odor in the flue at home and does not know the reason. Sometimes this is due to errors left during the construction process. So what issues should owners pay attention to during the construction process?
1. It is necessary to retain auxiliary flue. Each kitchen has a flue, and the flue is divided into main flue and auxiliary flue. The main flue runs through the entire building, while the auxiliary flue is relatively independent. Generally, the cooking fumes in a household enter the auxiliary flue and then enter the main flue through the holes on the partition, ensuring that each household's cooking fume is isolated. However, if the auxiliary flue is directly connected to the main flue, there may be smoke inversion or string due to low pressure.
2. Pay attention to the construction details. Firstly, the selection of the installation position for the range hood is very important. The shorter the pipe, the better. For the sake of aesthetics, some homeowners may pull the water pipes longer. In this way, after turning off the range hood, a large amount of oil fumes will accumulate in the pipeline, which cannot be discharged and then return to the room. In addition, in order not to damage the original main and auxiliary flue, the opening direction cannot be changed arbitrarily, and it is necessary to open it inside the auxiliary flue.
3. Pay attention to safety when smoking from windows
In order to avoid smoke issues, some homeowners have abandoned the original Jinan kitchen smoke exhaust pipes and directly opened holes in the windows for smoke exhaust. This is fine, but there are a few points to note.
Firstly, it is necessary to obtain the consent of the property before opening windows or walls; Secondly, pay attention to the issue. The end of a typical smoke exhaust pipe is made of metal. If the hole is too small, metal heat transfer may cause glass breakage and harm pedestrians. Moreover, the smoke pipe leads out of the window, and a strong north wind blows head-on, which can cause oil fumes to flow back. Try to lengthen and nest the pipes as much as possible to prevent rainwater from flowing into the pipes and leaving the windshield outside when it rains.
4. Regularly replace the check valve. If the auxiliary flue has been removed or the smoke control effect is good, use the flue check valve. In general, the check valve of the range hood is not effective, but installing a check valve in the flue can protect the range hood from backflow of smoke into the pipeline and range hood. But the check valve should be cleaned regularly after installation, otherwise it will open and fail. The flue check valve should be replaced every two years or so.
