Description

[Brief explanation of the drawing]

Fig. 1 is a block diagram showing the overall configuration of a preferred embodiment of the present invention, Fig. 2 is a diagram showing changes in temperature inside the drum during the drying period, and Fig. 3A shows a large object to be dried in the drum. A diagram showing the change in drying efficiency when drying by rotating in one direction, Figure 3B is a diagram showing the drying efficiency when drying an ordinary-sized object by rotating in one direction of the drum, Figure 3 C is a diagram showing changes in drying efficiency when a large object to be dried is dried only by forward and reverse rotation of the drum. 10 is a drum, 12 is a reversible motor, 1
4 is a motor driver, 16 is a motor controller, 18 is a temperature sensor, 20 is a computing unit, and 22 is a mode selector. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.

Claims (1)

[Claim for Utility Model Registration] Includes a drum for storing objects to be dried such as clothes, a drum drive means for rotating the drum, and a heating means for blowing warm air into the drum, and includes a drum for storing objects to be dried such as clothes, and a heating means for blowing warm air into the drum. A drum dryer that dries clothes, etc. by rotating the drum has a temperature detection section that detects the temperature inside the drum, and a temperature detection section that controls the temperature inside the drum to a predetermined temperature from the start of the drying operation based on the detection result of the temperature detection section. A drive control unit that controls the drum driving means so that the drum rotates in one direction during a preheating period until the drum rises, and rotates in forward and reverse directions during a constant rate period and a decreasing rate period thereafter. Characteristic drum dryer.
