DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer for drying clothes and the like.

[0002]

2. Description of the Related Art A clothes dryer proposed in Japanese Patent Application No. 3-245925 is equipped with a heat exchange type double-sided fan and blows dry air into a drying chamber in which a drying object storage drum is arranged. While circulating, external air is introduced as cooling air, heat is exchanged between the drying air and the cooling air by the double-sided fan to remove moisture from the drying air, and then the drying air is reheated by a heater to be dried. To the room.

The drum is rotatably supported by a rotary shaft, and the rotary shaft is supported by a metal support plate provided between both side walls of the dryer frame.

[0004]

In such a clothes dryer, the metal support plate is relatively strong, and the relatively strong metal support plate is provided on both side walls of the dryer frame. The strength has been strengthened by the presence. However, the upper wall of the dryer frame is easily deformed when a heavy and weak material is put thereon because the metal supporting plate is not installed.
