Abstract

A dryer and control method thereof are disclosed, by which energy saving and optimal temperature maintenance within a drying drum are enabled in a manner of diversifying a heater temperature by varying a rotational speed of a blowing fan used for the dryer. The present invention includes a drying drum for accommodating an object to be dried therein, a blowing fan provided to enable an air to pass through the drying drum, a heater heating an air supplied to the drying drum, a temperature sensor sensing a temperature within the drying drum, a driving motor generating a driving force to rotate the drying drum and the blowing fan, and a control unit controlling an RPM (revolutions per minute) of the driving motor to be varied according to a sensing result of the temperature sensor.

Description

technical field [0001] The present invention relates to a dryer for drying washed laundry, etc., and more particularly, to a dryer and a control method thereof. Although the invention is suitable for a wide range of applications, it is particularly suitable for maintaining an optimum temperature inside the drying drum by varying the speed of the fan used in the dryer. Background technique [0002] Generally, the dryer is used to dry wet objects (such as wet clothes, sheets, etc.) that need to be dried automatically. Dryers are divided into exhaust-type dryers and condensation-type dryers. Among them, exhaust-type dryers dry clothes by introducing external air, while condensation-type dryers remove moisture by circulating internal air, and the removed The moisture is condensed into water droplets and discharged, thus drying the clothes. [0003] Hereinafter, the configuration of an exhaust type dryer according to the related art will be schematically explained with referenc...
