Thank you very much for your link.
My dryer is on 2nd floor, the piple should be go outside from the roof. Now it is too cold to get there. I will check later.
I think this is not a good idea to let the dryer hot moist air vents inside the house. You will have moisture built up inside the house. Perhaps mole will grow inside your house

I saw those before. They have some chemical to remove the moisture but of course venting outside the house is better. Their idea is to help warming the house to save some energy.
