Abstract

The utility model relates to an electronic auto-controlled energy-saving one-way blowing machine, belonging to a blowing machine. The electronic auto-controlled energy-saving one-way blowing machine is the improvement of a one-way blowing machine composed of a casing, a wind wheel, a cage rotor, a main shaft, and a stator winding. Two sets of starting windings are opened. A time relay in an electric control box arranged on the casing of the blowing machine is used for controlling the conducting and the breaking of the starting windings. Each opened starting winding can be respectively connected with an indicating lamp. When the blowing machine is started, the two starting windings in a short-circuit condition, which enables the blowing machine to positively rotate; after the blowing machine is started, the time relay enables the two starting windings to break or be in a loading (the indicating lamp) condition and the two starting windings not to heat, so the utility model has the conspicuous effect that saves power and extends the lifetime of the blowing machine.
电子自动控制节能单向吹风机,属于吹风机类, 是对由壳体、风轮、鼠笼转子及主轴、定于绕组组成的 单向吹风机的改进,将两组起动绕组开路,由装在风 机壳体上的电控盒中的定时继电器控制起动绕组的 导通和断路,各开路的起动绕组可分别联接一个指示 灯;风机在起动时两起动绕组呈短路状态使风机正 转,风机起动后,时间继电器使两起动绕组呈断路或 有载(指示灯)状态;使两起动绕组不发热有明显的节 电和延长风机寿命的效果。
