[0010] 1. Only a single motor and a wind wheel are arranged in the shell, and three wind duct branches are arranged on the wind duct, namely, the first air outlet duct, the second air outlet duct and the ventilation duct, which are respectively connected with two air outlets and ventilation outlets. A single wind wheel is used to realize the functions of blowing and ventilation, which greatly reduces the volume of the heater and completes the transformation to lightweight and miniaturization.
