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, particularly night, affect easily people's sleep.
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 with speed-regulating function, include power supply, electric heating assembly, fan and connection fan and be connected motor, described electric heating assembly includes the first electric heating assembly and the second electric heating assembly, 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 input of motor, the four tunnel input by electric capacity connection motor.
As preferably, the input of the motor indicator lamp that is connected in parallel.
As preferably, 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 an adjustable temp. controller, 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, the five tunnel unsettled setting of described rotary switch.
Rotary switch has six pins, input connects power supply, the first via, the second tunnel, Third Road and the four tunnel connect respectively the first electric heating assembly, the second electric heating assembly, input end of motor, input end of motor, and then the four the tunnel access the input of motor by connecting first an electric capacity, the five the tunnel is unsettled setting.Rotary switch arranges 0 grade, fan, and 1,2 fourth gear all disconnects during 0 gear, and during the fan gear, Third Road is connected, and then motor is opened, the fan quick rotation, blowing cold air, and indicator lamp lights.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, the 4th route be in the setting of electric capacity, the Rational choice capacitance, be equivalent to a voltage impedance, reduce voltage, namely the motor input current reduces, and motor speed is slack-off, at this moment wind speed reduces, 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 current direction is preferably the path of no-voltage impedance, i.e. preferred Third Road, this moment, wind speed was larger, then blew out warm braw, and heating effect is better.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 with speed-regulating function, include power supply, electric heating assembly, fan and connection fan and be connected motor 5, power supply connects a rotary switch 1, and 1 input of rotary switch connects power supply, and the output of rotary switch includes four the tunnel at least, the first via of output connects the first electric heating assembly 3, the second the tunnel connects the second electric heating assembly 4, and Third Road connects the input of motor 5, the four tunnel input by electric capacity 2 connection motors 5.The input of the motor indicator lamp 6 that is connected in parallel.Rotary switch, the first electric heating assembly or the second heating component are connected in series with overheating protective element; the input of rotary switch is connected in series an adjustable temp. controller 7; electric heating assembly is connected in series with the first thermal circuit beraker 8 and thermal cut-off 9, and motor is connected in series with the second thermal circuit beraker 10.
Rotary switch has six pins, input connects power supply, the first via, the second tunnel, Third Road and the four tunnel connect respectively the first electric heating assembly 3, the second electric heating assembly 4, motor 5 inputs, input end of motor, and then the four the tunnel access the input of motor by connecting first an electric capacity, the five the tunnel is unsettled setting.Rotary switch arranges 0 grade, fan, and 1,2 fourth gear all disconnects during 0 gear, and during the fan gear, Third Road is connected, and then motor 5 is opened, the fan quick rotation, blowing cold air, and indicator lamp 6 lights.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, the 4th route be in the setting of electric capacity, the Rational choice capacitance, be equivalent to a voltage impedance, reduce voltage, namely the motor input current reduces, and motor speed is slack-off, at this moment wind speed reduces, 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 current direction is preferably the little path of voltage impedance, i.e. preferred Third Road, this moment, wind speed was larger, then blew out warm braw, and heating effect is better.In addition, also access overheating protective element in the circuit, damage device when avoiding overheated.
