Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter device for a clothes dryer that dries clothes by sending hot air into a rotating drum into which clothes and the like are loaded.

A conventional filter device of this kind has a configuration as shown in FIGS. 5 and 6, where a is a filter cover, b is a recess provided in the rear wall of the rotating drum, and c is a protrusion formed at the center of the bottom of the recess b. The holding material has the largest diameter near the tip.

d is a filter part interposed between the filter cover a and the recessed part b, the central part of which competes with the surface of the boss part e provided at the center of the filter cover d, and the outer peripheral part of the filter part that competes with the surface of the boss part e provided at the center of the filter cover d. There is a sheep inside. Here, the boss part e has a cylindrical shape, and a plurality of notches f that are long in the length direction of the boss part e are formed in the circumferential wall of the boss part e, thereby imparting elasticity to the circumferential wall of the boss part e. The above holding material c is attached to the boss part e.
This makes it easy to insert it inward.

Further, an IJ ring-shaped spring member g is disposed on the outer circumferential surface of the boss portion e, and the biasing force of this spring g ensures that the competitive state between the boss portion e and the holding member c is maintained. In the above configuration, the exhaust gas containing lint and the like reaches the filter portion d through the hole in the filter cover a, and the lint and the like are captured by the filter portion d, and exits to the outside through the exhaust hole h in the recess portion b.

However, according to the above-mentioned slow growth, some of the lint does not reach the filter part d, and is discharged to the outside as it is, and is discharged into the room.

That is, according to the mounting configuration of the filter cover a,
An exhaust flow i is formed from the hole in the filter cover a through the notch f to the inside of the recess b, resulting in a situation in which lint and the like cannot be captured by the filter part d. An exhaust flow j is generated from the gap between the green circumferential portion of the filter cover a and the green circumferential portion of the recess b, which reaches the inside of the recess b without passing through the filter portion d.

Although the generation of this exhaust flow i can be prevented to some extent by considering the shape, size, etc. of the filter cover a or the filter portion d, the generation of the above-mentioned exhaust flow i cannot be prevented. The present invention eliminates the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a rotating drum, which is rotatably supported within the dryer main body 2, and is rotated by receiving the rotational force of a motor 4 via a belt 3.
Reference numeral 5 denotes an opening/closing door, which opens and closes the clothes input port 6.

A suction bag 7 is installed on the side opposite to the opening/closing door 6 of the main body 2, and guides the air inside the drum 1 to the exhaust port 9 by the rotation of a fan 8 linked to the motor 4.

Also, the air is turned into hot air by the heater 10 before entering the rotating drum 1. Reference numeral 11 denotes a filter device, which is fitted with iron in a recess la formed on the back surface of the rotating drum 1 so as to be detachable from the clothes input port 6 side.

Next, the mounting structure and the like of the filter mounting 11 will be described.

The filter device 11 includes a filter cover 12 and a dish-shaped filter 13 that is detachable from the filter cover 12.
Both are made of resin material with high heat resistance. Reference numeral 13a denotes a filter section provided on the dish-shaped filter 13 and having an appropriate mesh.

The filter cover 12 has a plurality of ventilation rows 4 having a size that does not allow clothing to pass through between the center and the periphery, and the recess l in the periphery.
A concave portion 12a is formed for iron-bonding the outer peripheral frame 13b of the filter 13 located between the filter cover 12 and the filter cover 12. 15 is a rotating drum 1 at the center of the recess la.
A retaining member 16 projecting inward is a woven boss integrally formed in the center of the filter cover 13, and the outer circumferential surface of the retaining member 15 is filled with iron inside the boss.

Reference numeral 17 denotes a hollow portion formed by cutting the inner central portion of the boss portion 16 in the thickness direction;
The cross-sectional shape perpendicular to the length direction is approximately arc-shaped.

Reference numeral 18 denotes a protrusion provided on the inner circumferential surface of the post section 16 near the tip side, corresponding to the hollow section 17, and is engaged with a mating groove 19 formed in the circumferential direction of the circumferential surface of the holding member 15.

The center portion of the filter 13 is iron-fitted to the outer peripheral surface of the boss portion 16. Further, the outer peripheral frame 13b of the filter 13
The drum drum part 13c and the recess l which are aligned with the inner circumferential surface of the recess la
It has a contact bale portion 13d that airtightly abuts on the opening circumferential portion of a. That is, the outer peripheral frame 13b has a substantially L-shaped cross section. In addition. lb is an exhaust hole formed on the bottom surface of the recess la, and a handle portion iron-fitted to the boss portion 16, which is provided in the center of the filter 13. According to the above structure, the filter cover 1
A retaining member 15 provided in the recess la is filled with iron in the boss portion 16 of No. 2, and the projection 18 is fixed to the engagement register 19 due to the elasticity of the inner peripheral portion of the boss portion 16 due to the formation of the hollow portion 17. become.

With this configuration, the vent 14 of the filter cover 12
The exhaust flow that has passed through will necessarily pass through the filter section 13a. That is, in order to facilitate competition with the retaining material 15, a hollow part 17 is formed by inserting the inside of the boss part 16 in the thickness direction into the peripheral wall of the boss part 16, and unlike the conventional filter 13. A notch is not formed between the hub portion 16 and the boss portion 16, and no exhaust flow that does not pass through the filter portion 13a occurs in the vicinity of the post portion 16. Further, there is no need to tighten the boss portion with a spring material as in the past, the number of parts can be reduced, and there are no inconveniences such as the need for time and effort to attach the spring material.

As described above, according to the present invention, the boss portion of the filter cover does not have a notch that discharges the exhaust flow to the outside of the machine without passing through the filter, thereby preventing lint and the like from being discharged to the outside of the machine. Furthermore, since the filter cover and filter can be attached without requiring press-fitting of spring material, the number of parts can be reduced and work efficiency can be improved.
