Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a clothes dryer for drying clothes placed in a rotating drum.

BACKGROUND ART FIG. 4 shows the configuration of a conventional clothes dryer. That is, the rotation of the motor 1 is transmitted to the rotating drum 3 via the belt 2. The clothes placed in the rotating drum 3 are rotated and agitated while being hit by the hot air a that has passed through the heater 4 and are dried. The rotation of the rotary drum 3 requires a large reduction in rotation of the motor 1, and in order to adjust the tension of the belt 2, a tension pulley 6 is provided which is rotatably supported by a tension pulley shaft 5.

Problems that the invention aims to solve However, in the conventional configuration, if some force is applied to the belt 2 due to vibration during transportation, for example, and the position of the belt 2 shifts, the belt 2 hooked on the rotating drum 3 will not rotate. There is a risk that the rotating drum 3 will fall off the drum 3, and there is a problem that the rotating drum 3 will not rotate even if the user turns on the power.

This invention solves these problems,
The purpose is to reduce the risk of the belt falling off the rotating drum.

Means for Solving the Problems In order to achieve the above object, the present invention includes a belt that transmits the rotation of a motor, a rotating drum that rotates via the belt, and a drying object that is attached to the rotating drum and that is attached to the rotating drum. The lifter has a plurality of protrusions on the outside in the radial direction of the rotating drum, and the protrusions protrude from holes provided on the outer peripheral surface of the rotating drum, The protrusions are arranged at substantially the same intervals as the width of the belt, and the belt is positioned between these two protrusions.

Effect: With this configuration, it is possible to prevent the belt from being displaced on the outer peripheral surface of the rotating drum, thereby preventing the belt from falling off.

Embodiment Hereinafter, an embodiment of the present invention will be described in Figures 1 to 3.
This will be explained with reference to the figures.

As shown in FIG. 1, the construction of a clothes dryer according to an embodiment of the present invention is such that the rotation of a motor 11 is transmitted to a rotating drum 13 via a belt 12 at a reduced speed. The clothes put into the rotating drum 13 are
It is rotated and agitated while being hit by the hot air b that has passed through the heater 14 and is dried. In order to adjust the tension of the belt 12, the tension pulley shaft 1
Tension pulley 1 that is pivotally supported by 5 and rotates.
It is equipped with 6. A lifter 17 made of resin for stirring the clothes is provided inside the rotating drum 13, and is fixed to the cylindrical surface of the rotating drum 13 from the outside with a mounting screw 18. The rotating drum 13 is made of metal in consideration of the possibility of ignition and workability, and the lifter 17 is made of resin to have the most effective shape as its shape has a large effect on the drying performance of clothes. It is manufactured by

The relationship among the lifter 17, rotating drum 13, and belt 12 is shown in FIGS. 2 and 3. The protrusion 19 is used for positioning the lifter 17 before it is fixed with the mounting screw 18. The protrusion 20 is also used for positioning, and is configured so that the belt 12 is positioned approximately at the center, thereby preventing the belt 12 from being largely deviated from its normal position. That is, even if the belt 12 becomes twisted due to vibrations during transportation, the protrusions 20 keep the belt 12
can return to its normal position, and the rotating drum 13
The risk of it falling off can be greatly reduced.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the lifter is provided with a plurality of protrusions projecting outward, and the belt is disposed between these protrusions, so that the belt does not fall off from the rotating drum. It is possible to prevent the problem that the rotation stops due to the rotation.
