In order to more clearly show specific heating wire Winding Design of the present utility model, insulating part 1 simplifies in FIG and illustrates.Insulating part 1 is wound with three heating wire winding R1, R2 and R3 spaced apart from each other, wherein two heating wire windings R2, R3 are wrapped on the mid portion of insulating part 1, and another heating wire winding R1 is wrapped on the end of insulating part 1.Heating wire winding R2, R3 play the effect of heater, supply to dry hair after energising for heating to produce heat.And the effect of heating wire winding R1 in fact landing casting die, as shown in Figure 4, R1 connects with direct current machine M, and for reducing the direct voltage being supplied to direct current machine M, and R1 and R2, R3 are in parallel.
According to an embodiment of the present utility model, as shown in Figure 1, heating wire winding R2, R3 are all wrapped on insulating part 1 along equidirectional, in other words, in FIG from the right side to the left time, R2 and R3 is wound around all along clockwise direction.And R2 and R3 comprises contact A1, A2 respectively; B1, B2.When needs produce heat, for R2, from contact A1 input current, from contact A2 output current, as shown by arrows in FIG., electric current direct of travel is forward, according to Ampere's right-handed screw rule, produces the electromagnetic field pointing to the left side in figure; For R3, from contact B2 input current, from contact B1 output current, as shown by arrows in FIG., electric current direct of travel is oppositely, produces the electromagnetic field pointing to the right in figure, because electromagnetic field direction is contrary, cancels out each other, therefore can minimize produced electromagnetic field, even make produced electromagnetic field offset completely.In a word, in this first embodiment, two heating wire windings R2, R3 are wrapped on insulating part 1 along equidirectional, one of them heating wire winding R2 is passed to and the rightabout electric current of all the other heating wire windings R3, electromagnetic field direction is contrary thus, thus minimizes or counteract completely the electromagnetic field of induction.
According to second embodiment of the present utility model, as shown in Figure 2, heating wire winding R2 is wrapped on insulating part 1 along first direction, and heating wire winding R3 is wrapped on insulating part 1 along contrary second direction, in other words, in fig. 2 when from the right side to the left time, R2 is wound around along clockwise direction, and R3 is wound around in the counterclockwise direction.And R2 and R3 comprises contact A1, A2 respectively; B1, B2.When needs produce heat, for R2, from contact A1 input current, from contact A2 output current, as shown by arrows in FIG., electric current direct of travel is forward, according to Ampere's right-handed screw rule, produces the electromagnetic field pointing to the left side in figure; For R3, from contact B1 input current, from contact B2 output current, as shown by arrows in FIG., electric current direct of travel is forward, produces the electromagnetic field pointing to the right in figure, because electromagnetic field direction is contrary, cancels out each other, therefore can minimize produced electromagnetic field, even make produced electromagnetic field offset completely.In a word, two heating wire windings R2, R3 to be wrapped in opposite direction on insulating part 1 and to be passed to the electric current of equidirectional in this second embodiment, and electromagnetic field direction is contrary thus, thus minimizes or counteract completely the electromagnetic field of induction.
Although above-mentioned first and second embodiments, illustrate only two heating wire windings, according to caloric value requirement, the heating wire winding of more than three or three can also be set.When arranging three heating wire windings, in one example in which, three heating wire windings can be wrapped on insulating part along equidirectional, wherein at least one, such as 1 or 2 heating wire windings are passed to and the rightabout electric current of all the other heating wire windings.In another example, at least one in three heating wire windings, such as 1 or 2 edges are wrapped on insulating part 1 with all the other heating wire winding rightabouts, and these three heating wire windings are passed to the electric current of equidirectional.
In addition, as illustrated in fig. 1 and 2, two heating wire windings R2, R3 are formed by wavy heating wire.Compared with conventional spring-like heating wire, avoid under hair-dryer vibration occurs or the situation such as to fall, the short circuit caused due to overlying contact between each spring coil, thus use safer.And in order to save space, heating wire winding R1 can be formed by spring-like heating wire.
Fig. 4 is the schematic circuit of the heating component according to first exemplary embodiment of the present utility model, in order to be illustrated more clearly in the specific arrangements of heating wire winding, and simplifies.As can be seen from Figure, heating wire winding R2, R3 are passed to rightabout 220V alternating current, and heating wire winding R1 and heating wire winding R2, R3 are arranged in parallel, this heating wire winding R1 connects with direct current machine M, be configured to reduce the direct voltage being supplied to direct current machine, also be furnished with in heating wire winding R1 upstream and alternating current be transformed into galvanic device, such as diode etc.
In an embodiment of the present utility model, as shown in Figure 3, insulating part 1 is made up of more than one micarex 11, is made up of in figure 3 three micarexs.These three micarexs are in centrosymmetric mode, and namely longitudinal center's axis of three micarexs overlaps, and mutually arranged in a crossed manner, form an angle between two micarexs, when three micarexs, this angle is preferably 60 degree.In other embodiments, insulating part also can be made up of two or four or multiple micarex.Single micarex 11 U-shaped in general, has multiple little sawtooth for being wound around heating wire winding R2, R3, and has several in both sides, an end for being wound around the large recess of heating wire winding R1 in mid portion both sides.
According to an embodiment of the present utility model, can also provide a kind of hair-dryer (not shown), this hair-dryer comprises aforementioned heating component.
Owing to adopting such heating component, during blower operation, the electromagnetic field responded to is minimized or even eliminates, thus alleviates or avoid the damage of the health to the user using hair-dryer.
