Fig. 2 is fundamental diagram of the present utility model.
Wherein, 1-power input, 2-power control chip, 3-power set, 4-resistive heater, 5-microcomputerized controller.
Detailed description of the invention
Specific embodiment 1:
Fig. 1 and Fig. 2 constitutes specific embodiment of the utility model 1.
With reference to Fig. 1, the present embodiment comprises power supply 1, power control chip 2, power set 3, resistive heater 4 and microcomputerized controller 5; Described power input 1 is connected with microcomputerized controller 5; The output of described microcomputerized controller 5 is connected with the input of power set 3, resistive heater 4 respectively; The input of described microcomputerized controller 5 is connected with the output of power control chip 2, power set 4 respectively.
In the present embodiment,
With reference to figure 1, after power supply 240vac inputs, after resistance-capacitance depressurization module 1 then rectifying and wave-filtering, whole control system 30 ~ 40mA electric current will be supplied to.
Power input 1, provides two kinds of magnitudes of voltage, and a kind of is the 24v voltage supplying relay work, and another kind is available to the 12v voltage of MCU, ensure that the normal operation of resistive heater 4 and microcomputerized controller 5.
Power control chip 2, for realizing the designing requirement of this circuit standby power consumption < 0.5w, strengthening the stability and reliability of system, extending the life-span of foam maker.
Power set 3, this module for controlling the stirring-head of foam maker, i.e. d.c. motor.The power supply of this motor is provided through rectifying and wave-filtering by a linear transformer, but when receiving the signal of MCU, controls two-way optocoupler, and two-way optocoupler controls controllable silicon, and then controllable silicon realizes the control to motor input break-make again.This module is designed by the characteristic of linear transformer, namely the output voltage of transformer and load linear, when motor does not exist, linear transformer is approximate unloaded, voltage is at more than 24v, Zener diode will reverse-conducting, and On current makes the optocoupler conducting in this module, produces and feeds back signal to microcomputerized controller 5.
Resistive heater 4, this module is controlled by the break-make of break-make control realization to relay of microcomputerized controller 5 pairs of triodes, and relay, as switch, controls conducting and the disconnection of heat-generating disc.
Microcomputerized controller 7, this module is by LED display circuit, and switch detection circuit, temperature controller detection circuit, single-chip microcomputer oscillating circuit and reset circuit composition, complete the detection and control to various external signal.
With reference to Fig. 2, the operation principle of the present embodiment is as follows:
Resistance-capacitance depressurization and rectifying part, power unit.Supply MCU by ZD1 voltage stabilizing to 5v, jointly form voltage stabilizing 19v by ZD2 and ZD1 and supply relay.By MCU control Q2, then control low-power consumption by the break-make of Q2 control Q4.Low-power consumption principle be 19v and 5v that voltage stabilizing is obtained by Q4 conducting, because power unit provides constant current, when falling under voltage, lessen system power dissipation.MCU is to the control realization of two-way optocoupler U1 to the control of controllable silicon Q1, thus the electric power system controlling motor realizes control to motor.Under motor has N/R situation, U2 produces the different detection feeding back signal to MCU and realize motor, and when detecting motor and being abnormal, LED glimmers warning.By MCU by the control of R14 to Q5, realize the control to relay, temperature controller Thermostat is the test side of temperature, carrys out control relay when stop to MCU signal.Other I/O mouths of MCU connect other peripheral circuits of LED, button and single-chip microcomputer.Two LED realize Product Status display, and red light represents hot, i.e. heat-generating disc duty, and blue lamp represents cold conditions, and namely during revolution, heat-generating disc does not work.
Above disclosedly be only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and non-limiting the utility model, any those skilled in the art are not departing from the scope of the technical solution of the utility model, the Equivalent embodiments changing or be modified to equivalent variations is a little made when above-mentioned disclosed technology contents can be utilized, according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
