Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a clothes dryer, and more particularly to a yarn waste collecting device for collecting dust such as yarn waste generated from clothes.

[0002]

2. Description of the Related Art A conventional yarn dust collecting device for a clothes dryer includes a net filter using a polyester mesh or the like and a synthetic fiber or the like having an appropriate thickness for collecting fine dust passing through the net filter. The non-woven cloth filter has a double structure, and is composed of a filter guard that covers the net cloth and the non-woven cloth cloth so that clothes do not directly touch the filter surface. In addition, the main body is installed immediately before the hot air exhaust port in the drum, and the warm air exhaust port of the drum has a filter support that has the same dust collecting function as the net filter, a net filter, a non-woven filter, A lint collecting device consisting of a filter guard was attached and detached. This configuration is shown in Japanese Utility Model Laid-Open No. 4-108097.

[0003]

In the case of the conventional yarn waste collecting device having such a structure, it is necessary to remove the yarn waste collecting device from the inside of the drum every time maintenance such as cleaning is performed. In the case of clothes dryers, most of them are mounted on the washing machine with a dedicated stand, and the thread waste collection device that is usually installed in the back of the drum becomes deeper in the depth of the drum as the capacity increases. Even just doing it was a tedious task.
Further, when performing cleaning, it is necessary to separate the filter guard and the net filter to remove dust such as lint, but at that time, there is an unsanitary aspect such as dust scattering and direct contact with hands.

Further, if the clothes dryer is continuously used without cleaning the lint collecting device, not only the hot air flow will be deteriorated but the clothes dryer will not be able to exhibit its full performance, but also from the gap of the bearing portion of the drum or the like. It is important for the clothes dryer to simplify the cleaning of the lint collecting device, as lint debris leaks into the main body and accumulates on the motor part, etc., causing temperature rise and unexpected accidents. It was a challenge.

An object of the present invention is to provide a yarn waste collecting device for a clothes dryer, which has good operability and is considered in terms of hygiene.

[0006]

In order to achieve the above object, the yarn waste collecting apparatus of the present invention comprises a partition wall having an opening to the inside of the drum and being substantially parallel to the direction of the exhaust air of the air inside the drum. A plurality of dust collecting chambers are formed by covering the leeward side of the air in the drum opposite to the opening with a net filter such as polyester mesh, and the partition wall and the net filter forming the dust collecting chamber are insert-molded and heat welded. Alternatively, they are fixed to each other by adhesion or the like without any gap. Further, in consideration of fine dust that blows through the net filter, a double filter configuration is adopted in which a nonwoven fabric filter such as a synthetic fiber having an appropriate thickness is further stacked on the leeward side thereof.

[0007]

That is, since dust such as lint is separated and collected in each dust collecting chamber, it can be easily cleaned by only bringing the suction port of the cleaner close to and sucking it from the front face of the lint collecting device. Therefore, it is possible to clean without removing the lint collecting device from the inside of the drum, and it is not necessary to separate the lint collecting device for cleaning. It is also possible to prevent scattering. Further, the filter guard and the net filter can be integrally formed as compared with the conventional case, and the number of parts can be reduced, so that the productivity is improved.
