To with reference to accompanying drawing the present invention be described in more detail only by the mode of example below, accompanying drawing is the circuit diagram according to the embodiment of a kind of hair treatment device of the present invention.
Referring to accompanying drawing, be depicted as the circuit of implementing a kind of hair dryers of the present invention, this hair dryers comprises the casing of airduct (not shown) in it, a direct current motor M and driven in order to drive the fan (not shown) of air by this airduct by this motor M.This hair dryers also comprises 4 heating element heater R that are arranged in the airduct 1To R 4When operation, motor M energising drive fan or screw etc. form the analog of a blowing device, promote air through being in the heating element heater R in the airduct 1To R 4, thereby the hot-air of dry hair is provided.This circuit design becomes can control motor M and heating R 1To R 4Operation, and this circuit also comprises the first and second electric switch SW 1And SW 2, 4 diode D 1To D 4, a resistance R 5With a constant temperature switch T.
Motor M has a pair of choking-winding L 1And L 2, be connected with the two-terminal of armature, form motor circuit jointly.A filter capacitor C is in parallel with motor circuit.Heating element heater R 3And R 4And diode D 2And D 3Become bridge connection around motor M, the motor circuit diagonal angle is connected across between circuit node A and another circuit node K, and circuit node A is formed on diode D 2And D 3Negative pole between, and circuit node K is formed on heating R 3And R 4Between.Be noted that diode D 2And D 3In parallel with motor M respectively to realize the full-wave rectification effect.For making direct current generator operation, diode D 2And D 3Constitute a diode rectifier, flow through motor M with the electric current of the half cycle that alternately makes the AC power opposed polarity by equidirectional, and capacitor C keeps current of electric stable as much as possible by the elimination pulsation of current from node A to K.
Heating element heater R 1And R 2Be connected in series on the node Q, node Q is at heating element heater R 3With diode D 2Between form.Therefore, as shown in, heating element heater R 1To R 4Be actually and be cascaded.Thermostatic switch is connected to heating element heater R 1Far-end.Resistance R 5With diode D 4Link together, form a series connection circuit, its negative pole links to each other with node A.
Hair dryers passes through switch SW 1Adjustment, both can be connected on 230V/50Hz, also can be connected on the power supply of 120V/60Hz and move.Voltage switch SW 1Be a single switching mechanism, it comprises four anchor tip T 1To T 4, can be at first on off state (joint T 1-T 2) and second switch state (joint T 1-T 3/ T 2-T 4) between switch, first state is used for the 230V/50Hz operation, by a movable bridge contact (being represented by dotted lines) joint T 1And T 2Short circuit, second switch state are used for 120V/60Hz operation, by movable bridge contact (being represented by dotted lines) respectively with joint T 1And T 3And T 2And T 4Short circuit.Joint T 3With heating element heater R 2Adjacent to heating element heater R 1An end be connected and joint T 4With heating element heater R 1The other end adjacent to thermostatic switch T is connected.Joint T 2J joins with circuit node, and node J is at heating element heater R 4With diode D 3Between form.
Hair dryers is designed to the operation of three kinds of different operating temperatures or electrical power level, is respectively cold, height and low state, can use switch SW 2Select.Temperature switch SW 2Three selection joint T are arranged 1' to T 3' and a public joint T 4'.Joint T 1' with resistance R 5Free end connect.Joint T 2' and T 3' the two all receives switch SW 1Joint T 1On, T 2' directly connect, and T 3' through diode D 1Connect indirectly.Select termination T 1', T 2' or T 3' be connected to termination T 4' determined cold, high or low attitude working method respectively.Supply voltage is to be connected across public terminal T 4' and thermostatic switch T apply, the effect of the two is equivalent to two power ends of circuit.
At first referring to the working condition of 230V/50Hz.In the high state pattern, source current, when positive half cycle, sequential flow is crossed heating R 1, R 2, R 3(and through diode D 2Enter motor M) and R 4, and cross heating element heater R in the negative half period sequential flow 4(and through diode D 3Enter motor M), R 3, R 2And R 1In the low state pattern, the positive half cycle of source current is by diode D 1End, thus heating R 1To R 4Rated power reduce approximately half (reducing to 150 watts) from 300 watts, temperature also reduces by half.Diode D 1Can oppositely connect, with the source current of blocking-up negative half period.
Should be noted that in high and low state two-mode heating element heater R 1To R 4In fact all be cascaded.In cold conditions, have only the source current of negative half period can flow through diode D 4This source current can not pass through diode D 2And D 3, but can pass through motor M, and order is by heating element heater R 3, R 2And R 1Because resistance R 5Resistance value ratio heating R 1To R 3Much bigger, the source current amount that can pass through is very limited, and makes heating element heater R 1To R 3Heat effect be very restricted (60 watts).
Below referring to the situation of 120V/60Hz.In the high state pattern, the circulation path of source current negative half period current component I 1And I 2Expression.Current component I 1Only flow through heating element heater R 1, and current component I 2Sequential flow is crossed heating element heater R 2, R 3(and through diode D 2Flow through motor M) and R 4The circulation path direction of the positive half cycle of source current is opposite, is reverse current component I 2Sequential flow is crossed heating element heater R 4(and through diode D 3Flow through motor M), R 3And R 2
Heating element heater R 1Resistance approximately and heating element heater R 2, R 3And R 4The summation of resistance identical.Should note heating element heater R 2To R 4In fact still be cascaded, and heating element heater R 1In fact but in parallel with them.This heating element heater R 1With other heating element heaters R 2To R 4Actual parallel connection makes all heating element heater R 1To R 4Total resistance reduced approximately half.Along with supply voltage is reduced to only about half of 120V from 230V, the source current amount is compared practically identical with the ruuning situation of 230V/50Hz, thus heating element heater R 1To R 4Rated power still is approximately 300W.Therefore, at least in the high state pattern, in fact the performance of hair dryers is not subjected to the influence of the supply voltage that changes between 230V/50Hz and 120V/60Hz.
As the situation in the 230V/50Hz operation, when low state pattern 120V/60Hz operated, the positive half cycle of source current was by diode D 1End, so heating element heater R 1To R 4Rated power reduce to approximately half (from 300W to 150W), thereby temperature also reduces by half.Therefore, the performance of hair dryers in fact also is not subjected to the influence of mains voltage variations in the low state pattern.When cold conditions, supply voltage does not influence operation from the variation of 230V to 120V at all, and this is because electric heater R 1Reality to connect influence more little.But, make an appointment with half because supply voltage has reduced, heating element heater R 1To R 4Rated power also will reduce half and be about 30 watts.
Should be noted that and heating element heater R 1To R 4Compare, motor M is only drawn very little electric current, thereby its existence does not influence the analysis to source current that above provides substantially.When supply voltage when 230V fades to 120V, no matter at high state or low state, R 3, R 4Electric current remain unchanged substantially, same, current of electric is also constant.Therefore, the speed of motor M keeps identical substantially.Have only as heating element heater R 1To R 4Do the time spent in an air heat, motor speed is only critical, because it influences air velocity, thus the temperature of the hot-air of influence output.Therefore, in cold conditions, motor speed is so unimportant relatively.
Though diode only allows the electric current one-way flow, whole associated diodes group can reconnect by opposite direction and not influence interlock circuit total running in ac operation.Therefore, in a slightly different embodiment, diode D 2, D 3And D 4All connect, promptly allow diode D by rightabout 2And D 3Positive pole and diode D 4Positive pole connect, form circuit node A, A leads to a terminal of motor M again, and this does not influence the total operation of above-mentioned hair dryer machine circuit.
It is contemplated that hair treatment device of the present invention can take to be different from other form of hair dryers, for example curler, hair fixing device or air brush.
The present invention only gives out in the mode of example, and those skilled in the art can to described embodiment make various improvement and/or change and do not exceed as claims the special scope of the present invention that limits.
