Dryer and the control method of the same

Abstract

An object of the present invention is to provide a dryer and a method for controlling the same, in which a rotation speed of a drying drum is made to reach to a preset rotation speed regardless of a load of the drying object held in the drying drum. For this, the dryer includes a drying drum rotatably mounted in a body, a driving unit mounted to enable to vary a rotation speed of the drying drum, sensing means for sensing a load of the drying object in the drying drum, and a control unit for controlling the driving unit to vary a rotation speed of the driving unit proper to the load with reference to a sensing signal from the sensing means. For this, the method includes the steps of applying a drying course to start drying, sensing a load of a drying object with an electrode sensor after starting the drying course, and varying a rotation speed of the driving motor with the load sensed thus.

Description

technical field [0001] The present invention relates to a dryer for drying washed laundry, and more particularly, to a dryer in which the rotation speed of a drying drum is varied according to the load of drying objects to improve drying performance. Background technique [0002] Dryers for automatically drying wet objects after washing, such as clothes, generally have two types: exhaust type dryers and condensation type dryers. Among them, the exhaust type dryer draws in external air to dry clothes, while the condensation type dryer dries clothes through the circulation of internal air, and the moisture inside the dryer is removed, condensed into water droplets, and then discharged from the dryer. [0003] Referring to the accompanying drawings, briefly introduce the exhaust type dryer of the related art. [0004] Referring to FIG. 1 , a related art exhaust type dryer is provided with a drying drum 20 , a drying drum support 60 and a driving unit. Wherein, the drum 20 is ...

Problems solved by technology

[0015] For this reason, when the load of the drying object is less, the rotation speed of the drying drum 20 is increased to be higher than the preset rotation speed, which will cause the clothes in the drying drum 20 to stick to the inner peripheral surface of the drying drum due to the centrifugal force, so that the clothes Incomplete drying of laundry that is damaged and in contact with the inner peripheral surface of the drying drum

[0016] On the contrary, in the case of a heavy load of drying objects, the rotation speed of the drying drum 20 is lowered than the preset rotation speed, which reduces the rotation speed of the fan which rotates with the drying drum 20, so that it cannot provide enough hot air into the drying drum 20, thereby reducing drying performance

[0017] Therefore, thinner fabrics are more likely to be damaged, while thicker fabrics may not dry well and dry less efficiently
