I tried to look for a poser model of a hair dryer (appliance) in the site but I can't find it.

Can I request a poser model for it, or is there a link to one?

Max format Hair Dryer

You can  download the demo of studio max and convert the .max file to .obj which can be used in Poser.

Ockham has a 50's style one here:

Those are the only ones that I know of.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
