While you’re busy in the kitchen, your wife is in the living room, enjoying the air conditioning, eating sunflower seeds, and watching Korean dramas. You’ve already done all the preparatory work, sweating profusely, waiting only for the hot oil to be added. Of course, as my wife instructed, I should turn on the range hood first at this time. As soon as the range hood was turned on, before the stove fire was lit, my wife suddenly shouted: Why does it smell so bad? What’s going on?
After turning on the range hood, it draws in the bad smells from other people’s homes and sends them into your own home. There is a mesh at the inlet of the range hood, which is meant to ensure that the air flows outward; it seems that this mesh is damaged, causing the air flow to reverse direction.
The air drawn out by the ozone extractor is brought in by the air conditioner:lol:lol
My wife could smell the scent coming from within her own body; P
Then there’s no need for so many descriptions of various scenarios as a form of buildup.
When the range hood is turned on, the indoor pressure decreases, which can allow other odorous air currents to be drawn in. This kind of thing has never happened in my home. Since you have encountered it, it’s likely that the liquid seal in the drainage pipes of the toilet or bathroom in your home is missing, or there are damages to the pipes and ventilation channels, which allows the odor to be drawn out by the range hood.
The range hood creates a negative pressure inside the house, which draws in certain external or other odors into the home.
