Abstract
The utility model relates to a fan heater control circuit comprising a power source, electrical heating assemblies, a fan and a motor which is connected with the fan. The motor comprises two outlet ends and an inlet end. The two inlet ends are a first inlet end and a second inlet end. The number of turns of winding between the first inlet end and the outlet end is smaller than that between the second inlet end and the outlet end. A rotating switch is connected with the power source. The power source is connected with an inlet end of the rotating switch. An outlet end of the rotating switch comprises at least four circuits. A first circuit of the outlet end is connected with a first electric heating assembly. A second circuit is connected with a second electrical heating assembly. A third circuit is connected with the first inlet end of the motor. A fourth circuit is connected with the second inlet end of the motor. The fan heater control circuit is capable of adjusting not only heating watt level, but also speed of the fan. Therefore design is more humanized.
Description
Technical field
The utility model relates to a kind of control circuit of warm-air drier.
Background technology
Warm-air drier includes electric heating assembly and fan, by electric heating assembly then air heat is blown out by fan, generally regulate heating power by rotary switch in the prior art, and fan electromotor generally not having speed-regulating function, namely all is a speed running in the lower or higher situation of heating power, like this, when winter, when heating power is lower, because fan speed is larger, actual blow out for cold wind, so low-grade heating is not often used in fact.And fan speed large the time noise also larger.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides also adjustable warm-air drier control circuit of a kind of fan speed.
The technical scheme in the invention for solving the technical problem is:
A kind of warm-air drier control circuit, include power supply, electric heating assembly, fan and the motor that is connected fan, electric heating assembly includes the first electric heating assembly and the second electric heating assembly, described motor comprises two inputs and an output, described two inputs are respectively first input end and the second input, umber of turn between described first input end and the output is less than the umber of turn between the second input and the output, described power supply connects a rotary switch, the input of described rotary switch connects power supply, the output of rotary switch includes four the tunnel at least, the first via of output connects the first electric heating assembly, the second the tunnel connects the second electric heating assembly, Third Road connects the first input end of motor, and the four the tunnel connects the second input of motor.
As preferably, the first input end of the motor indicator lamp that is connected in parallel.
As preferably, described rotary switch, electric heating assembly, motor are connected in series with overheating protective element respectively.
As preferably, the input of described rotary switch is connected in series a thermostat, and described electric heating assembly is connected in series with the first thermal circuit beraker and thermal cut-off, and described motor is connected in series with the second thermal circuit beraker.
As preferably, rotary switch comprises six pins.
Motor is arranged two inputs, because umber of turn is different between two inputs and the output, then be equivalent to the resistance that accesses different, the number of turn is more, and resistance is larger, and then motor speed is slower, and the fan that then connects motor is slower.Rotary switch has six pins, and input connects power supply, and the first via, the second tunnel, Third Road and the four tunnel connect respectively the first electric heating assembly, the second electric heating assembly, motor first input end, motor the second input, the five the tunnel is unsettled setting, arranges 0 grade, fan, 1,2 fourth gear all disconnect during 0 gear, during the fan gear, Third Road is connected, then motor is opened, fan quick rotation, blowing cold air.This moment, the function of warm-air drier was equivalent to electric fan, only had blowing function, without heating function.In the time of 1 grade, the first via, the four tunnel is connected, and the second the tunnel, Third Road disconnects, then the first electrical heating elements heating, motor speed is slack-off, and at this moment wind speed reduces, and what produce by boasting is to be comparatively gentle warm wind, and noise is little, comparative comfort.In the time of 2 grades, all be communicated with, then electric heating assembly is all opened, and heating power is larger, and motor is preferably the little path of resistance, and namely wind speed is larger, then blows out warm braw, and heating effect is better.The first input end of the motor indicator lamp that also is connected in parallel, when then inputting by first input end, indicator lamp lights.In addition, also access overheating protective element in the circuit, damage device when avoiding overheated.
The beneficial effects of the utility model are: the utility model not only can be regulated the heating power size but also can regulate the wind speed size, designs more hommization.
Description of drawings
Fig. 1 is electrical block diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of warm-air drier control circuit, include power supply, electric heating assembly, fan and the motor 3 that is connected fan, motor comprises two inputs and an output, two inputs are respectively first input end 5 and the second input 4, umber of turn between first input end 5 and the output is less than the umber of turn between the second input 4 and the output, power supply connects a rotary switch 1, the input of rotary switch connects power supply, the output of rotary switch includes four the tunnel at least, the first via of output connects the first electric heating assembly 2, the second the tunnel connects the second electric heating assembly 7, Third Road connects the second input 4 of first input end 5, the four tunnel connection motors of motor.The first input end 5 of the motor indicator lamp 6 that is connected in parallel.In addition; rotary switch, electric heating assembly all are connected in series with overheating protective element; the input of rotary switch is connected in series a thermostat 7, and described electric heating assembly is connected in series with the first thermal circuit beraker 8 and thermal cut-off 9, and described motor is connected in series with the second thermal circuit beraker 10.
Motor is arranged two inputs, because umber of turn is different between two inputs and the output, then be equivalent to the resistance that accesses different, the number of turn is more, and resistance is larger, and then motor speed is slower, and the fan that then connects motor is slower.Rotary switch 1 has six pins, and input connects power supply, and the first via, the second tunnel, Third Road and the four tunnel connect respectively the first electric heating assembly, the second electric heating assembly, motor first input end 5, motor the second input 4, the five the tunnel is unsettled setting, arranges 0 grade, fan, 1,2 fourth gear all disconnects during 0 gear, during the fan gear, Third Road is connected, and then motor 3 is opened the fan quick rotation, blowing cold air, indicator lamp 6 lights simultaneously.This moment, the function of warm-air drier was equivalent to electric fan, only had blowing function, without heating function.In the time of 1 grade, the first via, the four tunnel is connected, and the second the tunnel, Third Road disconnects, then the first electrical heating elements heating, motor 3 rotating speeds are slack-off, and at this moment wind speed reduces, and what produce by boasting is to be comparatively gentle warm wind, and noise is little, comparative comfort.In the time of 2 grades, all be communicated with, then electric heating assembly is all opened, and heating power is larger, and motor is preferably the little path of resistance, and namely wind speed is larger, and indicator lamp 6 lights simultaneously, then blows out warm braw, and heating effect is better.In addition, also access overheating protective element in the circuit, damage device when avoiding overheated.
