The seamer processing for joining the lid and the support lid requires several types of production equipment according to the size of the drum, and it takes time to switch the production equipment, which is inefficient in producing many types. Work is not required, and a rotating drum can be formed by attaching the end cover, cylindrical body, and support cover with screws using a synthetic resin bottomed cylindrical base as a base, and assembling is easy to assemble various types of drums and mass production. Rich in nature.

することができる。Also, to form a compartment between the synthetic resin bottomed cylindrical base and the cylindrical body of the metal plate and between the bottomed portion and the support lid,
This has the effect of covering the rotating drum with a heat insulating layer, and the energy loss due to heat dissipation from the rotating drum surface can be extremely reduced, so that the drying efficiency can be improved and the drying performance can be improved.

可能となる。In addition, it has been clarified that clothes containing oxidized edible oil and the like during drying may generate abnormal heat when left unattended after drying. However, in the case of a conventional rotating drum made of synthetic resin, the rotating drum made of synthetic resin is the same as that described above. Because it melts and opens due to high temperature, new air is supplied and ignites.In this case, however, in such a case, if the ignition mechanism is shut off to prevent the air supply path from being formed, and if there is ignition burning, This is extremely effective also in terms of safety in which it is not squeezed. On the other hand, in the case of a conventional synthetic resin rotary drum, since it is formed by a surface having an inclination in a cylindrical body portion in processing and forming,
In order to rotate the rotating drum, a force is constantly applied outward to the belt suspended on the cylindrical body, so that the belt is easily removed. Alternatively, since a concave portion is formed in the cylindrical body of the rotating drum to form a baffle for stirring the clothes, sound was generated at a discontinuous portion of the cylindrical body due to the concave portion when the drum was rotated by the belt. According to the present invention, an ideal cylindrical body can be easily formed while improving the mass productivity of the assembly, so that it is possible to prevent the belt from coming off and generating abnormal noise.
