Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a long central axis of rotation in the substantially horizontal direction, and hot air flows in from the rear wall and from the front wall side, which has an opening for putting in clothes, after drying the clothes. This relates to a substantially cylindrical drum for a clothes dryer through which hot air flows out, and its purpose is to efficiently apply hot air to the clothes rolling inside the drum when the drum rotates, thereby increasing drying efficiency.

Conventional drums of this type generally have a configuration in which a large number of holes are bored in the center of the rear wall near the center of rotation, and hot air is sent into the drum through these holes. According to this configuration, the hot air that has entered the drum passes through the center of the drum and is discharged from the front wall, so although the parts of the clothes near the center of the drum are dried, the parts near the outer periphery are dried by the hot air. It has the disadvantage that it is difficult to dry because it is difficult to come into contact with it.

The present invention solves the above-mentioned conventional problems, and provides a configuration in which hot air is sent into the drum from near the outer periphery of the rear wall of the drum.

The present invention will be explained in detail below. In the figure, 1 is the main body,
Reference numeral 2 denotes an intake hole provided at the lower front of the main body 1, which is covered with an intake filter 28. Reference numeral 3 denotes a motor attached to the bottom of the main body 1, and a fan 4 whose suction side corresponds to the intake hole 2 is attached to one end of the rotating shaft, and a drum pump ~96 is provided at the other end of the rotating shaft. .

Reference numeral 6 denotes a drum, which has a substantially cylindrical shape and has a shaft 7 at the center of its disk-shaped rear wall. Reference numeral 8 denotes a heater mounting plate located at the rear of the rear wall of the drum 6, which has a disk shape and is fixed by main body 1Vc mounting means (not shown). Reference numeral 9 denotes a heater such as a nichrome wire heater or a sheathed heater, which is attached to the heater attachment plate 8Vc so as to be located between the heater attachment plate 8 and the rear wall of the drum 6. Reference numeral 10 denotes a bearing member provided on the heater mounting plate 8, which rotatably supports the shaft 7, thereby supporting the drum 6 so that its central axis of rotation lies in a substantially horizontal direction.

A belt 11 is stretched between the outer surface of the peripheral wall of the drum 6 and the drum pulley 5.

Reference numeral 12 denotes a lid that can freely open and close an opening 13 formed on the front surface of the main body 1, and has an exhaust port 14, which is covered from the inside with a filter 14a.

Reference numeral 15 denotes a clothes input port formed in correspondence with the opening 13 at the front of the drum 6, and a flange portion 16 at the peripheral edge thereof is rotatably supported by the main body 1 side via a bearing member 17.

Here, the drum 6 has an uneven portion 6a formed in a substantially corrugated shape in the circumferential direction on the inner surface of its peripheral wall, and a plurality of baffles 6b are integrally formed at appropriate intervals in the middle of the circumferential direction. be. Among the uneven parts 6a, the recessed parts 6C
- A plurality of holes 6 are provided in the outer circumferential portion of the rear wall of the drum 6 corresponding to
d is perforated.

The main body 1 has a structure in which the side, top, bottom, back, and front surfaces are airtightly connected to each other.
It is pressurized within the main body 1, and after contacting the heater 9 and turning into hot air, it enters the drum 6 through the hole 6d, passes through the inside of the drum 0, and is discharged into the atmosphere from the exhaust port 14.

In the above configuration, the hole 6d corresponds to the recess 6C on the inner surface of the peripheral wall of the drum 6, and due to the presence of the uneven portion 6a, a space is always created between the clothing and the peripheral wall of the drum 6. The hot air that enters the drum 6 through the holes 6d acts uniformly on all parts of the clothing inside the drum 6,
As a result, drying time can be shortened. In particular, clothing is pressed against the inner surface of the peripheral wall of the drum 6 when the drum rotates six times, but hot air definitely enters between the clothing and the peripheral wall of the drum 6, and hot air does not reach the clothing near the center of the drum 6. Since it is easy to move, it ensures sufficient contact between clothes and hot air, resulting in stable drying performance.

As described above, according to the present invention, by improving the formation position of the hole for sending hot air into the drum and the shape of the peripheral wall of the drum, it is possible to apply the hot air to the entire clothing, and especially to the clothing and the peripheral wall of the drum. It becomes possible for hot air to enter between the layers, thereby improving drying performance.
