DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer for drying clothes in a rotary drum which is rotationally driven by a motor.

[0002]

2. Description of the Related Art Conventionally, this type of clothes dryer has been constructed as shown in FIGS. Hereinafter, the configuration will be described.

As shown in the figure, a body 1 is provided with a rotary drum 2 for stirring clothes therein, and a plurality of baffles 3 are fixed in the rotary drum 2. The double-blade fan (condensing means) 4 is rotatably provided at the rear part of the rotating drum 2 to exchange heat between the cooling air 5 and the circulating air 6, and also to circulate the circulating air in the rotating drum 2 through the heater 7 and the baffle 3 which are heat sources. 6 is circulated. The fan case 8 forms a labyrinth structure with the both-wing fans 4 and is held by the body 1.

The drain port 9 is provided in the fan case 8 and drains water droplets formed by condensing steam generated from clothes in the rotating drum 2 in the fan case 8 by heat exchange by the double-blade fan 4. The motor 10 drives the rotary drum 2 and the double-sided fan 4. The hose holder 11 is inserted and fitted inside the drain hose 12, and holds the drain hose 12 from the outer peripheral direction.
At the same time, the elastic claw portion 13 is fitted to the body 1 to hold the drain hose 12 on the body 1. The packing 14 is formed in a sponge shape and is attached to the outer peripheral portion of the drainage port 9 to seal the hose holder 11 and the drainage port 9.

The operation of the above structure will be described. When the motor 10 rotates and the rotary drum 2 and the double-blade fan 4 rotate, circulating air 6 and cooling air 5 are generated, and the circulating air 6
Is heated by the heater 7 to become hot air, and the rotary drum 2
After being introduced into the inside and exchanging heat with the clothes 15, the circulation of returning to the both-wing fan 4 again is repeated. Furthermore, the circulating air 6 that has become hot and humid is cooled by the blades of the double-bladed fan 4 and is cooled by the cooling air 5.
It is heat-exchanged and condensed, and the condensed water is discharged from the drain port 9.

The hose holder 11 has a structure in which the elastic claw portion 13 is detachably attached to the body 1 by a claw fitting, so that the hose holder 11 has a distance required for the detaching stroke between the hose holder 11 and the drain port 9 of the fan case 8. Reference numeral 14 fills the gap and responds to the movement of the hose holder 11 when the hose holder 11 is attached and detached.

The fan case 8 is fixed to the flange surface of the body 1 with a screw, and the tip of the drainage port 9 is higher than the upper end of the flange on the lower surface of the body 1 for assembling or maintaining, so that pseudo-condensed water flows. , Is set lower than the lower end of the fan case 8 that houses the double-blade fan 4. Therefore, at the height of the body 1 in which space is saved, the distance from the upper end of the flange to the lower end of the fan case 8 is inevitably narrow, and by fitting with the hose holder 11,
It is difficult to configure the tubular portion of the drain port 9 having a sufficient length to absorb vapor leakage and vertical displacement of the fan case 8 with respect to the hose holder 11. In addition, it is difficult to reduce the size of the double-blade fan 4 for forming the tubular portion of the drainage port 9 because the heat exchange performance is deteriorated.

[0008]

In such a conventional dryer, the fan case 8 and the hose holder 11 are attached to the body 1, respectively, and the fan case 8 and the hose holder 11 are directly fitted to each other. Since there is no gap between the drain port 9 and the hose holder 11 in the up-down direction, the center positions may be displaced or they may not be mounted so that they are parallel to each other. Has a problem that the condensate and steam flow out through the gap between the drainage port 9 and the hose holder 11.

The present invention has been made to solve the above problems, and an object of the present invention is to improve the sealing property between the drain port and the hose holder and to improve the quality.

[0010]

In order to achieve the above object, the present invention condenses a rotary drum rotatably disposed in a body and steam generated from clothes in the rotary drum by heat exchange. Means, a drain port communicating with the condensing means for discharging condensed water, and a drain hose connected to the drain port via a hose holder to discharge the condensed water to the outside of the body, the hose holder, An elastic packing is formed at one end so as to face the drain port, and an elastic packing is engaged, and the drain hose is connected to the other end, and the elastic claw portion provided on the hose holder is detachably locked to the body. Then, the packing is watertightly pressed against the drainage port as a means for solving the problem.

[0011]

According to the present invention, the elastic claw portion provided on the hose holder is detachably locked to the body by the above means for solving the problem, and the packing is watertightly pressed against the drain port.
It is possible to secure the sealing property against condensed water and moisture against vertical displacement, center displacement or inclined installation of the drain port of the fan case with respect to the hose holder.

[0012]
