Excuse me, is the intelligent shared clothes rack placed in the hotel hygienic? Can it really dry clothes?

Hello! I saw this smart clothes rack when I was staying in a hotel. It looks like an ordinary clothes hanger, but there is a vent in it. The blowing wind can dry clothes. Just hang the clothes on the hanger. At that time, I dried a close-fitting dress and it dried in less than three hours. It seems to be a * * * hanger called "Bake". I hope it can be adopted.
