1. An apparatus for drying an object, the apparatus comprising:
a housing configured to provide an airflow channel having an airflow inlet and an airflow outlet;
one or more radiation energy sources configured to generate infrared radiation and direct the infrared radiation toward an exterior of the housing, the energy of the infrared radiation being directly transferred to the object in a radiation heat transfer manner;
an airflow generating element contained in the housing and configured to generate an airflow through the airflow channel to blow the object for decreasing the temperature of the object irradiated by the infrared radiation; and
a device controller configured to control operation of the airflow generating element and the one or more radiation energy sources, wherein
when the device controller detects an abnormity of the airflow generating element, the device controller is configured to turn off both the airflow generating element and the one or more radiation energy sources, wherein the device controller is configured with an analog to digital converter (ADC) module, the ADC module is operated to sample a drive current to a motor of the airflow generating element, the abnormity of the airflow generating element is detected when the ADC module detects an abnormal current value of the drive current.
