Most of the time I use a clothes line. It's cheap! But when it's humid in summer, you can hang your wet clothes out for days and it will never dry it will however sour and mildew! In Winter your wet clothes will freeze I have had this happen, it's really funny when you can stand your pants up in the corner. LoL. So that means a clothes dryer comes in handy. This is the set I purchased in the 90's so they are kinda old. For the most part, still working. Except the dryer got soooo hot I couldn't even touch it. Needless to say I couldn't use it. (tumble drum---->)
A dryer is a very simple machine. It has a control center at top...mine has 3 switches the temperature selector, the start button, and the cycle timer switch. Then the cabinet on mine is like one piece of metal bent to a 3 sided configuration, then the front with the door attached, and the top...inside you have the drum it simply sits in there is turned by a motor and a belt much like in your car only smaller.

This is the control center from the back (top photo) showing the 3 electrical components, I had to replace the one on the end the shaft was broken off the temperature selector knob, I accidentally broke if off when I was moving the dryer out of the house...I got a used one at the appliance store downtown for $10.
