Description
Technical field
The present invention relates to a kind of control system, especially a kind of Novel microcomputer controls household electrical appliance.Belong to small household appliances technical field.
Background technology
Raising along with people's living standard, in society, the people of coffee for drinking gets more and more, and during modulating coffee, generally require and make foam milk, in order to enable to be formed in milk easily and quickly milk foam, it is most commonly that use foam maker, owing to milk foam is the milk product that mixes fine and closely woven with air, so the mode making milk foam is to be squeezed in milk by air.But, the reliability control system of foam maker the most on the market, stability are not enough so that it is high that machine exists power consumption, the problem that the life-span is short.
Summary of the invention
The invention aims to solve above-mentioned problem of the prior art, it is provided that a kind of simple in construction, energy-conserving and environment-protective, a kind of Novel microcomputer easy to use, that increase the service life control household electrical appliance.

Fig. 2 is the fundamental diagram of the present invention.
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 the specific embodiment 1 of the present invention.
With reference to Fig. 1, the present embodiment includes 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 outfan of described microcomputerized controller 5 input with power set 3, resistive heater 4 respectively is connected；The input of described microcomputerized controller 5 outfan with power control chip 2, power set 4 respectively is connected.
In the present embodiment,
With reference to Fig. 1, after power supply 240vac inputs, after resistance-capacitance depressurization module 1 then rectifying and wave-filtering, it will thus provide to whole control system 30～40mA electric current.
Power input 1, it is provided that two kinds of magnitudes of voltage, a kind of is the 24v voltage for relay work, and another kind is available to the 12v voltage of MCU, it is ensured that resistive heater 4 and the normal operation of microcomputerized controller 5.
Power control chip 2, for realizing the design requirement of this circuit standby power consumption ＜ 0.5w, strengthens the stability and reliability of system, extends the life-span of foam maker.
Power set 3, this module is 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, is controlled two-way optocoupler, and two-way optocoupler controls controllable silicon, and controllable silicon realizes the control to motor input break-make the most again.This module is designed by the characteristic of linear transformer, the i.e. output voltage of transformator is linear with load, when motor not in the presence of, linear transformer approximation zero load, voltage is at more than 24v, Zener diode will reverse-conducting, conducting electric current make the optocoupler in this module turn on, generation feed back signal to microcomputerized controller 5.
Resistive heater 4, the break-make of relay is controlled by this module by the break-make control realization of audion by microcomputerized controller 5, and relay, as switch, controls conducting and the disconnection of heat-generating disc.
Microcomputerized controller 7, this module, by LED display circuit, switch detection circuit, temperature controller detection circuit, single-chip microcomputer oscillating circuit and reset circuit composition, completes the detection to various external signals and control.
With reference to Fig. 2, the operation principle of the present embodiment is as follows:
Resistance-capacitance depressurization and rectifying part, power pack.Supply MCU by ZD1 voltage stabilizing to 5v, collectively constitute voltage stabilizing 19v by ZD2 Yu ZD1 and supply relay.Controlled Q2 by MCU, then controlled low-power consumption by the break-make of Q2 control Q4.Low-power consumption principle is that 19v with 5v voltage stabilizing obtained is turned on by Q4, owing to power pack provides constant current, lessens system power dissipation under voltage in the case of fall.MCU is to the control to controllable silicon Q1 of the control realization of two-way optocoupler U1, thus the electric power system controlling motor realizes the control to motor.Motor have without exception in the case of U2 produce the different MCU that feeds back signal to and realize the detection to motor, when detecting motor exception, LED flashes warning.By MCU by the R14 control to Q5, it is achieved the control to relay, temperature controller Thermostat is the test side of temperature, controls when relay stops to MCU signal.Other I/O mouths of MCU connect LED, button and other peripheral circuits of single-chip microcomputer.Two LED realize Product Status and show, red light represents hot, i.e. heat-generating disc duty, and blue lamp represents cold conditions, and i.e. during revolution, heat-generating disc does not works.
Above disclosed only presently preferred embodiments of the present invention, not the present invention is done any pro forma restriction, although the present invention is disclosed above with preferred embodiment, but and the non-limiting present invention, any those skilled in the art are in the range of without departing from technical scheme, make when available above-mentioned disclosed technology contents and change or be modified to the Equivalent embodiments of equivalent variations a little, the equivalent variations made according to scope of the present invention patent, still belongs to the scope that the present invention is contained.
