Abstract
An electric iron control circuit belongs to the technical field of electric appliances. The electric iron control circuit comprises a power supply, a switch, a microprocessor, a thermistor, a temperature sensor and an indicator lamp. The control end of the switch is connected with the signal output end of the microprocessor, one end of the power supply is connected with the switch, the other end of the power supply is connected with the thermistor connected with the switch, the temperature sensor is fixed on the thermistor, the output end of the sensor is connected with the input end of the microprocessor, and the input end of the indicator lamp is connected with the output end of the microprocessor. The electric iron control circuit has the advantage that a steam spraying type electric iron has the functions of adjusting temperature and producing steam. A spraying device is arranged on some electric irons, the trouble of manual water spraying is removed, medical wetting is even, and ironing effect is better.
Description
Technical field
The invention belongs to technical field of electric appliances, particularly a kind of electric iron control circuit.
Background technology
Electric iron is the instrument of smooth clothes and cloth, and power is generally between 300-1000W.Its type can be divided into: plain edition, temperature-adjusting type, steam spray type etc.The plain edition electric iron structure is simple, low price, manufacturing and easy to maintenance.Temperature-regulated iron can be mixed and automatically be regulated temperature in 60-250 ℃ of scopes, can automatic cut-off power, and can adopt the temperature that is fit to press according to different dress materials, come to get power saving than plain edition.
Summary of the invention
Deficiency for prior art exists the invention provides a kind of electric iron control circuit.
Technical scheme of the present invention is achieved in that this electric iron control circuit comprises that power supply, switch, microprocessor, thermistor, temperature sensor and indicator lamp form, wherein the control end of switch is connected with the signal output part of microprocessor, one end of power supply is connected with switch, the other end is connected with thermistor, thermistor was connected with the beginning, temperature sensor is fixed on the thermistor, the output of sensor is connected with the input of microprocessor, and the input of indicator lamp is connected with the output of microprocessor.During device work, by thermistor, temperature sensor detects the temperature of thermistor and outputs to microprocessor the switch closure electric current, when temperature reaches setting value through switch, microprocessor sends the cut-off signals driving switch and opens, the duty of indicator lamp real-time displaying device.
Advantage of the present invention: the existing temperature adjustment function of steam spray type electric iron, can produce steam again, what have goes back the fit on sprayer unit, the trouble of having exempted artificial water spray, and medical treatment is wetting more even, ironing effect is better.
Description of drawings
Fig. 1 is electric iron control circuit schematic diagram.
The specific embodiment
Detailed structure of the present invention is illustrated in conjunction with the embodiments.
This electric iron control circuit as shown in Figure 1, it is 87C51 that microcontroller is chosen model, temperature sensor is selected AT590, thermistor is selected MZ21-N8R0RMJ.
This electric iron control circuit comprises that power supply, switch, microprocessor, thermistor, temperature sensor and indicator lamp form, wherein the control end of switch is connected with the signal output part of microprocessor, one end of power supply is connected with switch, the other end is connected with thermistor, thermistor was connected with the beginning, temperature sensor is fixed on the thermistor, the output of sensor is connected with the input of microprocessor, and the input of indicator lamp is connected with the output of microprocessor.During device work, switch closure, electric current passes through thermistor through switch, temperature sensor detects the temperature of thermistor and outputs to microprocessor, when temperature reaches setting value, microprocessor sends the cut-off signals driving switch and opens, the duty of indicator lamp real-time displaying device.
