Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer with a rotating drum.

Structure of a conventional example and its problems A conventional rotary drum type clothes dryer will be explained with reference to FIG. In Fig. 1, 1 is a body case with an entrance 2 for clothing on the front and an intake port on the bottom, and 4 is an entrance 2.
5 is a backing provided on the edge of entrance 2,
Reference numeral 6 denotes a rotating drum that is provided within the fuselage case 1 and whose center of rotation is set in the horizontal direction. This drum 4 includes a disk-shaped disk 8 having a disk-like shape at the front and a flange 7 at the center, and a disk-like circular board having a bearing 9 fixed to the center and having a large number of ventilation holes 1o.
11, and a body plate 12 is sandwiched between the two.

In the gap between the drum 4 and the body case 1, a heater plate 15a having an insulator 14 for holding the heater 13 is fixed to the body case 1, and its outer periphery is open to allow air to circulate. The drum reinforcing plate 15b also serves to reinforce the circular substrate 11 and rectify the intake air from the gap between the heater plate 16a and the drum. A shaft 16 for supporting the drum 6 by a bearing 9 is fixed to the body case 1.

On the other hand, a bearing material 17 is attached to the inner surface of a flange 7 provided on a disc 8 constituting the front part of the drum 4, and a front support plate having an outer diameter that can slide on the inner diameter of this bearing material 17. 1
The drum 6 is pivotally supported by 8 and is rotatable within the fuselage case 1. A ventilation hole 19 is provided at the lower part of the disc portion of the front support plate 18 to allow air inside the drum 6 to flow out of the drum 6.
An opening 21 into which the filter 20 is inserted is provided on the lower surface, and a filter cover 22 that holds the filter 2o and has an air passage is fixedly held.

The filter cover 22 contacts the opening 26 of the fan case 25 of the fan 24 directly connected to the motor 23 to connect the air passage to the fan case 25.
is supported and fixed via a buffer rubber 27. The rotation of the drum 6 is driven by a pulley 2 attached to a motor 23.
This is done via a belt 28 that is wrapped around the belt 7.

In the above configuration, the drying of the cloth in the drum is carried out by the motor 23.
The outside air is sucked in through the outer periphery of the heater plate 15a and the drum reinforcing plate 15b by the fan 24, which is driven to rotate continuously, is heated by the heater 13, and enters the drum 6, exchanging heat with the cloth and filling the ventilation holes. 7 inside the fan case through 19
The clothes are dried by being pressurized by the tube 24 and discharged into the fuselage case 1 through the exhaust pipe 29.

However, in the conventional configuration, the gap between the heater plate 15a and the drum reinforcing plate 15b is wide, and the gap at the opening is wider than near the center of the drum, so the amount of air that hits the heater 13 attached to the outer periphery of the heater plate Also, due to the low wind speed, the heater 13 became abnormally red hot, causing phenomena such as burning of clothing and disconnection of the heater 13.

OBJECTS OF THE INVENTION In order to eliminate the conventional drawbacks, the present invention improves the shape of the openings of the heater plate and the drum reinforcing plate, and provides durability.
To provide a clothes dryer that prevents local abnormal heating.

Structure of the Invention In order to achieve the above object, the clothes dryer of the present invention has a rear end of a rotating drum that stores clothes supported by a shaft fixed to the main body, and a front end supported by a front support plate fixed to the main body. , a drum reinforcing plate is provided on the rear surface of the drum, a heater plate holding a heater is provided in the gap between the drum reinforcing plate and the main body, and the outer periphery of the heater plate is pushed toward the drum side, and the heater plate of the drum reinforcing plate is The corresponding part is molded into a circular cross-section, narrowing the space between the heater plate and the drum reinforcing plate, and increasing the speed of the air hitting the heater.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIG. In FIG. 2, the same components as those in the conventional example are designated by the same numbers, and their explanations will be omitted.

In FIG. 2, by providing a recess with a circular cross section in the vicinity of the heater part of the drum reinforcing plate 15b, and further adding a step to the drum side on the circumferential part of the heater plate 15a, the heater plate and the drum reinforcing plate By reducing the gap between the openings 15b and 15b, the speed of air hitting the heater 13 during intake is increased during operation. Thereby, when the heater 13 is energized, the cooling effect of the heater 13 can be increased and abnormal heating of the heater 13 can be prevented.

Effects of the Invention As is clear from the above embodiments, according to the present invention, by narrowing the space between the drum reinforcing plate and the heater plate, the speed of air hitting the heater during intake increases, and heat is removed from the surface of the heater.
It prevents abnormal heating of the heater, prevents partial splinters on clothes and breaks of the heater, and also has the effect of increasing the strength of the parts themselves since the heater plate and drum reinforcing plate are stamped.
