Definitions
- the invention relates to an electrical circuit arrangement for an electrical consumer, in particular for an electric hair dryer, fan heater or the like, with two first and second resistors arranged in parallel to one another, at least one of which is a second heating resistor and the other in particular a first heating resistor, with a switch , with an AC voltage source being connectable to the resistors, and with a DC fan motor which is connected to one of the resistors via a rectifier circuit.
- blower motor is connected to the middle branch of a diode bridge, which is connected on the one hand to taps of the two heating resistors and on the other hand to a pole of the supplying AC voltage source.
- the two heating resistors are connected to the other pole of the AC voltage source via switch contacts. If only one switching contact is closed, one of the two heating resistors is flowed through by both half-waves of the alternating current, while only one half-wave is applied to the blower motor.
- the rectifier circuit has only two rectifiers arranged antiparallel, to the connection point of which one of the connection points of the direct current blower motor is connected.
- the rectifier circuit according to the invention has only two rectifiers. This represents a reduction in the number of electrical components required, which leads to significant cost savings in particular in the case of a mass-produced product such as a hairdryer or a fan heater. However, the function of the circuit arrangement has not changed. Furthermore, by closing the switch mentioned, the total heating power and the total blower power is achieved.
- the two rectifiers are connected to two tapping points of the first heating resistor.
- the two tapping points on the first heating resistor can be chosen freely.
- the voltage present at the direct current blower motor can thus be influenced by an appropriate choice of the tapping points.
- the two tapping points or the one tapping point are arranged symmetrically with respect to the base points of the first heating resistor. In this way it is achieved that the first heating resistor in both Half waves of the alternating current is loaded equally.
- the voltage drop across the DC fan motor 1 1 can be set by the tapping points 1 2, 1 3. The greater the distance from the base points 14, 1 5 to the respective tapping points 1 2, 1 3, the smaller the voltage applied to the DC fan motor 1 1. This can be used in particular when using low-voltage blower motors to set the required operating voltage.
- these are interchangeable with resistors such that a total of at least one heating resistor remains in the circuit arrangement.
- the respective heating resistor in FIGS. 1-3 can be replaced in whole or in part by a corresponding resistance component.
- the resistance component is designed as a single resistor or as a plurality of resistors connected in series.
- the electrical connection points to the direct current blower motor (1 1) or to the rectifier diodes (8,9) are to be defined between the series connected resistors, so that the electrical components do not have too much power for all operating modes is present. This is achieved, inter alia, by selecting the resistance values according to the positions of the electrical connection points (12, 13, 16, 19, 20) in FIGS. 1-3.
