The present invention relates to a laundry dryer having a hot air supply device in a top cover.

Recently, a laundry dryer capable of washing and dewatering laundry as well as drying has been provided. In the laundry dryer, a washing tank provided for washing and dehydrating laundry is provided to dry, and the inside of the washing tank is configured to supply hot air by a hot air supply device during drying.

Japanese Patent Laid-Open No. 2000-279681 discloses it, and in particular, in the above-described Fig. 3, the hot air supply device is provided in the top cover mounted on the upper part of the outer box accommodating the washing tank described above.

In this case, the hot air supply device has an intake port at the rear portion, and sucks air outside the washing machine from the intake port to generate warm air, and supplies the warm air to the inside of the washing tank.

However, in this case, rain water may invade the hot air supply device from the intake port, and there is a possibility of foreign matter intrusion. For this reason, it is common to cover the intake port with a cover which is integral with the top cover or separately attached thereto.

In the above configuration, when the hot air supply device sucks air outside the washing machine from the intake port, dust floating in the air is also sucked up. For this reason, the suctioned dust adheres to the peripheral edge of the intake port and the inner surface of the cover which covers it, and it is piled up repeatedly. It is also conceivable that the accumulated dust is sometimes sucked into the hot air supply device and spouted with the warm air to contaminate the laundry during drying.

For this reason, it is necessary to clean the peripheral edge of the intake port to which the dust is attached and the inner surface of the cover covering the intake port from time to time. There was a problem that it was necessary to put and carry out, and the work was difficult and sufficient cleaning was not possible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a laundry dryer which can easily and sufficiently clean a portion to which dust is attached.

In order to achieve the above object, the laundry dryer of the present invention includes a top cover on an upper side of an outer box for accommodating a laundry provided for washing and dehydration and drying of laundry, and insulates the top cover from the outside of the washing machine through an intake vent to warm air. And a hot air supply device for supplying the warm air to the inside of the washing tank, wherein the external air intake port communicates with the air flow passage and has a side wall that forms an air passage facing the intake port of the hot air supply device. It is characterized in that the formed inlet cover is detachably provided.

According to the above, when the hot air supply device sucks air outside the washing machine from the intake port, dust floating in the air is attached to the periphery of the intake port and the inner surface of the intake cover covering the intake port, but the dust is attached. Are all exposed by removing the inlet cover, and in the exposed state, cleaning of the dust-attached portion can be easily and sufficiently performed.

In this case, a dust removal filter may be provided in the air passage of the inlet cover.

In this case, the dust removal in the air is prevented by the dust removal filter from being sucked into the hot air supply device. Thereby, dust adheres to the dust removing filter, but the dust removing filter is also exposed by removing the inlet cover, so that the cleaning of the dust removing filter together with the circumferential edge of the inlet or the inner surface of the inlet cover is performed in the exposed state. It can be done easily and sufficiently.

The dust removing filter may be detachable.

In this case, by removing the dust removal filter, cleaning thereof and cleaning of the inner surface of the inlet cover can be made easier and more sufficient.

In addition, the dust removing filter may be provided on the inlet cover so as to be opened and closed by a self-hinge mechanism.

In this case, opening of the dust removal filter facilitates its cleaning and cleaning of the inner surface of the inlet cover, thus making their cleaning easier and even more sufficient. In this case, even when the dust removal filter is opened, the dust removal filter is not lost because it is integrally formed by the inlet cover and the self-hinge mechanism.

In addition, the external air intake port may be formed on the lower surface of the intake port cover. Further, the external air intake port may be formed on the side wall of the intake port cover at a position offset from the position opposite to the intake port of the warm air supply device.

In this case, the air outside the washing machine is bent from the outside air intake port of the intake port cover and sucked into the intake port. Since the intake port and the external air intake port do not overlap, invasion of rainwater and foreign matters can be avoided thereby.
