Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a rotating drum that is rotatably disposed inside the main body, the front wall side of the rotating drum is divided into a rotating part and a fixed part, and hot air is introduced into the rotating drum from the fixed part side. A heater having a positive resistance temperature characteristic is housed in the hot air cylinder,
The hot air cylinder is made of resin.

FIG. 3 shows an enlarged view of the main parts of a conventional clothes dryer, in which a is a main body, b is a front plate of main body a, and C is a rotary drum rotatably disposed within main body a.

The front wall of the rotating drum C is a rotating drum. The front wall 1 rotation part β is connected to the peripheral wall of the arm C, and the front wall fixed part e is rotatably supported by the outer periphery of the inner peripheral edge of the front wall rotation part. The front wall fixing part e is fixed to the front plate via a mounting member, and the peripheral flange part g of the opening f of the front plate and the periphery 7 flange part of the clothing slot of the front wall fixing part e i
A para-yang j is attached to the peripheral flange part g so that a para-yang j made of rubber is interposed between.

In addition, a hot air intake hole k is formed in the front wall fixed part e,
A hot air cylinder m containing a heater 1 having a positive resistance temperature characteristic is connected to this, and hot air enters the rotating drum C via the heater 1 by the blowing operation of the fan.

Here, if a heater 1 having a positive resistance-temperature characteristic is used as a heating element, the maximum temperature of this heater 1 is 200°C.
Since the hot air cylinder m.

The mounting member (not shown) for attaching the front plate to the front wall fixing portion e, and the cover member n at the inlet may be made of resin.

However, these resin members were all attached to the front wall fixing part e with screws and nuts, which resulted in poor workability and increased cost due to the large number of parts. In addition to the above-mentioned resin members, it is necessary to attach members such as a bearing member O and felt to the front wall fixing portion, and there has been a strong demand for a reduction in the number of assembly steps.

The present invention solves the above-mentioned conventional problems, and embodiments thereof will be described below. In FIGS. 1 and 2, 1 is a main body, on which a rotating metal drum 2 is rotatably arranged. The front wall portion of the rotating drum 2 includes a substantially donut-shaped front wall rotating portion 3 connected to the peripheral wall of the drum, and an inner circumferential edge of the front wall rotating portion 3 rotatably supported by the outer circumferential edge via a bearing 4. It is divided into a substantially donut-shaped front wall fixing part 5. Reference numeral 6 denotes a clothing inlet formed at the center of the front wall fixing part 6; 7 refers to the front of the main body to which the front wall fixing part 5 is attached via a resin attachment member 8;
The face plate has an opening 9 which corresponds to the input port 6. 1Q and 11 indicate peripheral flange portions at the input port 6 and opening 9; 012 is a ring-shaped cover member;
It is made of resin and has grooves 12a and 12b into which the peripheral flange portion 10.11 is fitted over the entire circumference.

Reference numeral 13 indicates an intake port formed on the main body front plate 7; 14 indicates a hot air intake hole provided in the front wall fixing portion 5 so as to communicate with the intake port 13 through the inside of the hot air cylinder 16 made of resin; and 16 indicates a hot air intake port. The heating element supported by the body 15 is a semiconductor heater having positive resistance temperature characteristics.

Here, the mounting member 8. Cover part 12. Hot air cylinder 1
5 are all made of resin, and these members are integrated with the front wall fixing part 5 by outsert molding without using screws, nuts, etc.

A lid 17 opens and closes the opening 9, and has an outside air intake port 18 facing the intake port 13. 19 is a filter.

The rotating drum 2 has a large number of ventilation holes 21 in an inner recess 20 formed by protruding the center of the rear wall outward, and a filter 22 and a filter cover 23 can be detachably attached to the recess 20. It is installed. Further, a fan case 26 containing a fan 24 is provided behind the rotating drum 2, and the fan 24 is connected to a rotating shaft 27 of a motor 26 via a belt. 28 is an exhaust air cylinder communicating with the fan case 26. In addition, the rotation shaft 27 of the motor 26
is equipped with a drum boot IJ30 that connects the rotating drum 2 via a drum belt 29. 31 is door knocking.

According to the above configuration, the rotation of the motor 26 causes the rotating drum 2 and the fan 24 to rotate, thereby causing the outside air intake port 18. Hot air enters the 5-rotation drum 2 via the filter 199 heating element 16 and the hot air intake hole 14,
Furthermore, - this hot air is subjected to a clothes drying operation. As a result, the air containing moisture passes through the filter 22,
The fan 24° exits the aircraft via the exhaust wind body 28.

Here, a cover member 12 that covers the peripheral flange portion 11 of the opening 9 of the main body front plate 70 and the peripheral flange portion 10 of the input port 6 is shown. Both the mounting member 8 and the hot air cylinder 15 are made of resin, and these members are integrally molded with the front wall fixing part 6 by outsert, that is, the front wall fixing part 5 which is the basic structure.
It is inserted into a mold for resin molding and molded into one piece.

The airtightness of the joint surface between the front wall fixing part 6 and the hot air cylinder 15 can be improved, and the mounting accuracy between the main body front plate 7 and the front wall fixing part 6 can be improved, and the number of screws and nuts used can be extremely reduced. However, the workability is good, and the cost can be reduced by reducing the number of parts per assembly man-hour. In particular, in the cover member 12, there is no loosening of screws due to vibration, and concentricity between the input port 6 and the opening 9 can be ensured.

As described above, according to the present invention, in a configuration in which a heater with a positive resistance temperature characteristic is used as a heating element, a hot air cylinder for accommodating the heater, a cover member covering an inlet and an opening, and a front wall fixing part are attached to the main body. The three mounting parts that are attached to the front panel are made of resin, and these parts are integrated into the front wall fixing part by outsert molding, making it possible to significantly reduce the number of assembly steps and parts, and also prevent burns. It is possible to prevent this from occurring, and furthermore, it is possible to improve the mounting accuracy between the front wall fixing part and the main body front plate, and to stabilize the concentricity between the opening and the input port.
