Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drum-type clothes dryer that supplies heated air into the drum to dry clothes.

In general, in clothes dryers that use P, T, or C heaters as the heat source, the air guiding structure that guides heated air into the drum is such that the heat source part, which is composed of the heater, electrode plate, insulating plate, etc., is It was fixed using.

Therefore, the conventional air guide structure has a complicated shape as an assembly part.

Furthermore, in order to stabilize the amount of heat generated and the temperature of the hot air during the installation work to the dryer main body, the work efficiency was poor because the installation had to be done securely without any gaps.

In addition, similar points were pointed out in terms of services such as when replacing heaters, as mentioned above.

The present invention has been devised to eliminate the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is an outer box of the dryer, 2 is a rotary drum rotatably supported in the outer box 1, and has an opening 3 in the center of the front surface for inserting the material to be dried. is provided with a large number of exhaust ports 4.

5 is a motor that connects the rotating drum 2 and the ventilation fan 6.
are rotated via belts 7 and 7', respectively.

Reference numeral 8 denotes a cylindrical protective frame with one end positioned within the front opening 3 of the rotating drum 2 and the other end fixed to the main body 1, and a supply port 9 for supplying hot air is formed between it and the opening 3 of the drum 2. are doing.

Reference numeral 10 denotes a cylindrical bearing holder located between the outer box 1 and the drum 2 at appropriate intervals on the outside of the periphery of the protective frame 8, and has a mounting portion formed at the side end of the outer box 1. It is attached to the outer box 1 by fixing it with screws.

The bearing holder 10 has a through hole 11 that communicates with the supply port 9 and an air guide tube 17 described later, and has a felt 12 attached thereto to ensure airtightness with the drum 2, and further allows the drum 2 to rotate freely. A plurality of drum supports 13 are arranged to support the drum.

Reference numeral 14 denotes a hollow heater mounting base located below the bearing holder 10 and fixed to the bottom of the outer box 1;
4 has a bulge having a flat surface and a hanging wall as shown in FIGS. 1 and 2 at the edge of the upper opening, and also introduces the outside air introduced into the outer box 1 into the inside. It has a ventilation port 15.

The ventilation hole 15 is preferably provided on the rear wall surface of the heater mount 14.

Reference numeral 16 denotes a heater disposed on the insulating plate 25. The heater 16 is fixed to the heater mount 14 by placing and fixing the insulating plate 25 on the bulge of the heater mount 14.

The insulating plate 25 is preferably fixed to the heater mount 14 by sandwiching the edge of the insulating plate 25 between the lower end of the air guide tube 17 described later and the flat surface of the heater mount 14.

Reference numeral 17 denotes a cylindrical air guide tube 17 that is disposed between the heater mount 14 and the bearing holder 10 and serves to guide the hot air generated from the heater 16 into the drum 1 through the through hole 11 of the bearing holder 10. The air guide tube 17 is made of a heat-resistant synthetic resin, for example, a polycarbonate resin,
The lower end is fitted into the bulge of the heater mount 14 covering the opening, and the upper end is fitted into the through hole 11 of the bearing holder 10.
It is attached against the felt 12 attached around the periphery for airtightness.

There is an external wall surface 17 between the wind guide tube 17 and the heater mounting base 14.
The airtightness is maintained by the contact between A and the inner wall surface 14A.

Further, a rib 17B for positioning is integrally molded on the introduction port 24 at the upper end of the wind guide tube 17 with the main body of the wind guide tube 17, and by inserting and engaging the rib 17B into the through hole 11 of the bearing holder 10. The bearing holder 10 and the wind guide tube 17 are reliably connected.

The procedure for assembling the above configuration is as follows:
4, an insulating plate 25 on which a heater 16 is mounted is placed on the heater mounting base 14, and a heater 16 is mounted on the insulating plate 25 on which the heater 16 is mounted.
The air guide tube 17 is fitted to cover the outer case 1, and the inlet 24 of the air guide tube 17 is engaged with the periphery of the through hole 11 of the bearing holder 10, and then the bearing holder 10 is fixed to the front surface of the outer box 1 with screws. This completes the process.

When replacing a heater, etc., remove it by reversing this procedure.

In the figure, 18 is a drum 2 in which the fan 6 is installed.
A casing arranged at the rear, 19 an exhaust port, 20 a drum shaft fixed to the casing 18, 21 a bearing arranged on the drum 2, 22 a filter cover, 23 a lint filter, and 26 an outside air inlet It is.

In the above configuration, the outside air introduced into the outer box from the outside air inlet by the fan enters the heater mount from the ventilation hole provided in the heater mount, and the air guide tube heated by the heater and the bearing holder are heated by the heater. It is guided into the drum from the supply port through the through hole, dries the clothes in the drum, and is discharged to the outside from the exhaust port.

As described above, according to the present invention, by being equipped with a wind guide tube,
The connection between the heat source part and the heated air supply port to the drum, which requires airtightness, and the connection between the heat source part and the main body in this state can be easily and reliably performed, thereby preventing carelessness during assembly work. It is possible to prevent performance deterioration caused by this process, reduce man-hours, stabilize quality, and reduce costs.

Furthermore, in terms of service, heater replacement etc. can be performed easily and quickly.
