In general, the dryer includes a drum accommodating the object to be dried, a driving source for driving the drum, heating means for heating air introduced into the drum, and a blower unit for sucking or discharging air in the drum.

 The dryer can be classified into an electric dryer and a gas dryer according to the heating method of heating the air. The electric dryer heats air using electric resistance heat, and the gas dryer heats air using heat generated by combustion of gas. If the dryers are classified differently, they can be classified as condensation dryers and exhaust dryers. In the condensing dryer, the air in the drum is heat exchanged with the laundry, and the air in a highly humid condition circulates without being discharged to the outside of the dryer. In the separate condenser, heat is exchanged with the outside air to generate condensed water. In the exhaust type dryer, the air in the drum is heat-exchanged with the laundry, and the air in a highly humid condition is directly discharged to the outside of the dryer. If the dryer is classified into another method, it may be divided into a top loading method and a front loading method according to a method of inputting a dry matter to the dryer. In the top loading method, the laundry is loaded at the top of the dryer, while in the front loading method, the laundry is loaded at the front of the dryer.

The conventional dryer described above has the following problems.
