The present invention relates to a tumble dryer.

The rotary dryer generally used is as follows.

1 is a schematic cross-sectional view of a conventional general hot air dryer.

Referring to FIG. 1, in the conventional hot air dryer, a blower 3 is installed on an upper portion of the body 1, and the blower 3 serves to blow external air into the dryer.

In addition, the coil heater 2 is provided inside one of the early stages.

The blower 3 sends heat generated by the coil heater 2 to a drying chamber to dry the dry matter placed on the drying rack.

Hot air is supplied into the drying chamber through the porous plate 4 having a plurality of holes provided on the side of the dryer.

In addition, all the drying racks 5 are fixed by the drawer type drying rack.

Since the hot air of such a conventional hot air dryer is transmitted more strongly from the upper side and the side inside the dryer, the temperature of the side portion is higher than the temperature of the central portion, and the temperature of the upper portion is higher than the temperature of the lower portion.

Accordingly, there is a disadvantage in that the hot air is not evenly transmitted and the drying is not even and the drying is biased to one side.

In addition, there is a disadvantage in that the time is excessively consumed to dry the whole because it is not evenly dried, and accordingly the cost is excessively consumed.

The present invention has been made to solve the problems of the prior art, an object of the present invention to provide a rotary dryer that can dry the drying evenly dried inside the enclosure.

Another object of the present invention to provide a rotary dryer that can be rotated stably so that the building does not fall.

The present invention for realizing the object of the present invention is a rotary dryer which is composed of a housing, a rotating unit installed inside the housing to rotate the building, a heating unit for applying heat to the rotating unit, and a driving unit for driving the rotating unit. The rotating unit may include a rotating frame rotated by the driving unit and a channel mounted on the rotating frame, and a speed adjusting unit adjusting the speed of the driving unit; A position adjusting unit for adjusting a position of the rotating unit; A temperature controller for controlling an internal temperature of the enclosure; And a control unit having a control switch to control the rotating unit, the heating unit, the driving unit, the speed adjusting unit, the position adjusting unit, and the temperature adjusting unit.

As such, the present invention spreads the dry evenly on the tray, and then dry while rotating the tray, the drying can be easily dried.

Hereinafter, embodiments of the present invention will be described based on the drawings.
