Hair dryer wiring diagram - I took apart a hair dryer and made a circuit diagram (beneath). I am a great deal more routinely willing than electrically, however would really like to have a primary knowledge of what's occurring on this circuit.
Sw1 is a 3 role rocker switch, model sr-seventy one, feature type "k". Its 3 positions are off(open circuit) - fan low(proper side handiest) - fan excessive(each right and left sides connected to common).
Request for help: does every body understand how to put off the heating detail from a hair dryer to have it most effective blow cold/cool air?? i've opened it up and there are plenty greater wires than i expected.? i have just sufficient electric expertise to be a touch bit above risky, so i concept it might be excellent to invite for help.? thanks!.
For decrease velocity or heater level the ac mains voltage is fed via a diode to every of the hundreds. The diode has the feature in that it best conducts present day in one direction so simplest the advantageous parts of the ac voltage waveform makes it to the motor or heater. The bad parts of the ac voltage waveform are reduce off via the diode and so for this reason do now not deliver electricity to the load. The net impact of that is that the motor or heater get approximately half of the strength and as a result the motor turns slower or the heater does now not emit as much warmness.
I found your schematic specifically perplexing, so i redrew it. In wellknown, strive do draw high voltage factors at the top and occasional voltage ones on the lowest facet of the schematic. In this specific case the tool is ac powered, so pick an orientation as you desire however stay with it. Indicators (not present here) should commonly flow from left to proper.
