DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer of an air circulation type and dehumidification type, and more particularly to a clothes dryer having a compact structure and improved drying efficiency.

[0002]

2. Description of the Related Art Generally, as a clothes dryer, an air circulation type / dehumidification type, a rotary drum type, and a bathroom clothes dryer are known.

[0003] Of these, bathroom clothes dryers have a long drying time and require a large amount of power consumption and the like, and are therefore disadvantageous in drying efficiency and economic efficiency as compared with dehumidification type and rotary drum types.

In addition, the air circulation type / dehumidification type and the rotary drum type have a problem that the rotary drum type generates a large amount of noise during operation and abnormally raises the indoor humidity. .

[0005]

As described above, in the conventional various clothes dryers, the noise during operation is lower in the air circulation type / dehumidification type dryer than in the bathroom clothes dryer or the rotary drum type dryer. Although it is small and can suppress an increase in indoor humidity, it has a drawback that it is expensive and its structure cannot be made compact because a heat pump system is used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides an inexpensive, compact structure and significantly improved drying efficiency in an air circulation / dehumidification type clothes dryer. It is intended to provide a dryer.

[0007]

In order to achieve the above object, the present invention relates to a clothes dryer which is installed in a closed drying chamber and circulates air in the drying chamber to dry clothes by dehumidification. The clothes dryer has a dry air outlet, a warm air outlet, and a humid air inlet formed on the front side of the housing, and a dry air intake formed on the back side thereof. A passage is defined, and a dew condensation plate is provided facing the humid air passage side, a radiating fin connected to the dew condensation plate and facing the dry air passage side, and a hot air blast fan installed in the humid air passage. It is characterized by comprising a fan, a fan for dry air installed in the dry air passage, and a drain portion installed in the wet air passage and removing moisture condensed by the condensation plate to the outside.

[0008] A cross flow fan is preferable as the fan for hot air and the fan for dry air.

It is preferable that a thermostat for preventing the temperature in the drying chamber from excessively rising is installed near the hot air outlet from the viewpoint of safe operation, and the PTC which requires almost no waiting time at the start of operation as a heater. A ceramic heater is good.

[0010]

As is apparent from the above constitution, the clothes dryer according to the present invention sucks the humid air in the drying chamber from the humid air suction port into the inside of the machine, and causes the dew condensation plate to cause dew condensation to perform dehumidification. Therefore, the size can be reduced as compared with the conventional heat pump type dryer.

Furthermore, by employing two circulation systems, a warm air circulation system and a dry air circulation system, it has become possible to quickly remove clothes in the drying room.

Further, the dry air introduced from the outside is blown out from the dry air outlet by driving the dry air fan. However, since the radiating fins are set so as to face the dry air passage, the radiating fins are provided. The condensation plate can be quickly cooled through the fins, thereby increasing the condensation efficiency and shortening the drying time.

Further, the temperature inside the drying chamber does not exceed the upper limit value due to the thermostat for preventing the temperature from excessively rising in the drying chamber installed near the hot air outlet.

Further, if a PTC ceramic heater is used as the heater, warm air heated to a predetermined temperature from the start of the operation of the dryer can be circulated in the drying chamber.
