[Detailed Description of the Invention] Industrial Application Field The present invention relates to a clothes dryer for drying clothes, and in particular to fixing and holding a capacitor and a lead wire.

BACKGROUND ART The structure of a conventional clothes dryer will be explained with reference to FIG. That is, a rotary drum 2 is rotatably housed in a main body 1 of the clothes dryer, and a belt 4,
The rotational force of the motor 3 is transmitted via the pulley 5. A double-blade heat exchange fan 6 having a heat exchange function and an air blowing function is disposed behind the rotating drum 2, and is generally made of plastic or the like. The double-blade heat exchange fan 6 transmits the rotation of the motor 3 to the fan pulley 9 using a fan belt 7 and a motor pulley 8.
It is fixed to the transmission and rotates. Also, motor 3
A bracket 10 for holding the is attached to the upper part of the main body 1. A cooling ventilation hole 12 is provided in a back plate 11 covering the back surface of the main body 1, and is configured to take in cold air for cooling the double-winged heat exchange fan 6 within the main body 1. A center shaft 14 that pivotally supports the rotating drum 2 is attached to a drum holder 13 provided at the rear of the main body 1 by tightening, and a double-wing heat exchange fan (hereinafter referred to as a fan) 6 is also freely rotatable by the center shaft 14. It is pivoted on. This fan 6 is covered by a fan case 16, and both sides of the fan are separated by a fan seal 17 (felt or the like) provided on the outer periphery of the fan 6 and a partition plate 18 of the fan case. A circulation port 20 provided in a fan case 16 and the rear of the rotating drum 2 are airtightly communicated with each other by a drum seal 24, and the humid air inside the rotating drum 2 is sent to the fan 6. An opening 29 at the front of the rotating drum 2 can be opened and closed by a door 27.
Further, the fan 6 is provided with a circulation path 33 that circulates the circulating air from the fan case 16 to the front part of the drum.
Before leading to the rotating drum 2, the air is passed through a DTC heater 34 and is again sent into the drum together with the warm air.

Furthermore, the conventional configuration will be explained with reference to FIGS. 4 and 5. That is, the motor 3 is provided at a corner of the body 1, and a capacitor 35 for generating electricity in the motor 3 is attached to the motor flange directly to the motor body with a tapping screw 41. The wiring 36 of these electrical components is bundled with a lead wire holder 39 using a lead wire attachment hole 38 of a flange 37 provided in the body 1. Further, a bundle of lead wires from each electrical component is connected by a closed terminal connector 40 or the like. Since these wires 36 are close to the outer circumference of the rotating drum 2, they are tied together with a closed terminal connector 40 along the body flange at a location with sufficient space to prevent the lead wires from coming into contact with the rotating body. I'm here. Furthermore, in order to prevent the lead wires from coming into contact with the edge of the end face of the flange 37 of the body 1, the current situation is to protect the lead wires with vinyl tape or the like.

In addition, as shown in FIG. 5, a lead wire 36 is routed from the controller 32 on the operation panel located at the front of the clothes dryer to the rear along the corner of the body 1 to connect the motor 3 and the capacitor 35. Together with the lead wires, they are tied together with a closed terminal connector 40.

Problems to be Solved by the Invention In such a conventional configuration, it is necessary to route the lead wires 36 along the flange 37 of the body 1 so that the lead wires do not come close to the motor pulley rotating body or the drum rotating body. Flange 3 of body 1
7, it was necessary to attach and hold the lead wire in several places with the lead wire 39. Also, connect the lead wire itself to body 1.
The lead wire itself was covered with a vinyl chloride tube or the like to protect it from the edge of the flange 37. Furthermore, the lead wires from the capacitor attached to the motor bracket were also processed and wired at the same time, resulting in a large number of wires to be processed and an increase in the number of wiring steps.

This invention solves these problems,
The purpose is to reliably protect the lead wire wiring from the rotating body of the drum and the rotating body of the motor pulley, and at the same time protect it from the edges of the body flange end face, and to streamline the installation work of the capacitor.
