I have a hood over my stove.

It has a fan to pull smoke and steam up out of the cooking space.

It blows the fan output right in my face, rather than outdoors.

This does not contribute anything useful to the cooking process.

It's fairly common in America. It's so common it appears it doesn't even cross your mind to consider it as something that might be desirable or useful.

(For those who say "well fix it then", I've looked, but unfortunately if you just put a hole in the wall behind the fan you end up in another exterior wall that meets up with the house there. It's not an easy cheap fix.)
