BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer for drying clothes and the like, and more particularly, to a dryer whose capacity varies depending on the amount of the object to be dried.

In general, the clothes drying apparatus is a device for drying a drying object such as clothes by hot air, and is divided into a dryer having only a drying function and a laundry dryer including a washing function.

In addition, the dryer is largely divided into an exhaust type dryer and a condensation type dryer.

The exhaust type dryer forms the air of high temperature and low humidity by the heater while sucking the low temperature air from the open suction duct and then sucks it into the drum. The high temperature and low humidity air sucked into the drum is transformed into medium and high temperature air by material / heat transfer with the cloth in the drum and is exhausted to the atmosphere through the discharge duct.

On the other hand, the condensation type dryer is supplied with the high temperature and low humidity air heated by the heater into the drum, and turns into medium and high temperature air by mass and heat transfer with the cloth in the drum, and the material and heat transfer to the low temperature and low humidity air while passing through the condenser. . The low temperature and low humidity air is reheated by the heater and then circulated inside the drum to change into medium temperature and humid air again, and the cloth is dried while continuing the above cycle.

However, the conventional dryer has a problem that the object to be dried is dispersed in the inner lower part of the drum, and heat generated by the heater is uniformly supplied to the entire interior of the drum, so that energy efficiency is low and drying time is delayed.

The present invention has been made to solve the above-mentioned problems of the prior art, the drying volume and energy efficiency of the drum as the internal volume of the drum is varied according to the amount of the object to be dried and the hot air supplied into the drum is evenly supplied into the drum. The purpose is to provide this high dryer.

The drum is characterized in that the inclined arrangement.

The rotary vane is characterized in that a plurality provided to partition the inside of the drum into a plurality of spaces.

The variable member is disposed in each of the partitioned spaces.

The adjusting means is characterized in that the spring for elastically supporting the variable member to the drum.

The dryer is characterized in that it further comprises an exhaust means for exhausting the air to dry the drying object in the drum to the outside.

On the other hand, when the blowing fan 96 is rotated, ambient air of the heater 32 flows into the heater 32 and is heated by hot air A having high temperature and low humidity, and the hot air supply duct 34 and the tub are heated. Passed through the opening 17 of (12) in order to flow into the opening hole 21 of the drum (20).

The hot air A introduced into the opening hole 21 of the drum 20 is a space between the variable members 70, 71, 72, 73 and the opening hole 21 of the drum 20. In, dry the cloth while in contact with the cloth.

Hereinafter, the drying process of the fabric in more detail as follows.

The hot air (A) and the drying object (m) in each space and evenly distributed into the space partitioned by the rotary blades 40, 41, 42, 43 as the drum 20 is rotated It contacts and dehydrates the dry object m.

In addition, hot air in each of the spaces is blocked by the variable members 70, 71, 72, and 73 so as not to spread deep inside the drum 20, and the rotary vanes 40, 41, 42 ( It passes through the hot-air flow path hole 45 formed in 43, and it moves to the side space, and takes the water of the drying object m in a side space again.

As described above, the air dehydrating the drying object (m) passes through the through hole 22 of the drum 20 and is moved between the drum 20 and the tub 12, and then the exhaust of the tub 12 is exhausted. It is exhausted to the outside of the dryer through the communication port 16 and the exhaust means (90).
