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 modulate in coffee process, 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, at present the reliability control system of foam maker on the market, stability is not enough so that there is power consumption height in machine, the problem that the life-span is short.

Detailed description of the invention
Specific embodiment 1:
Fig. 1 and Fig. 2 constitutes specific embodiments of the invention 1.
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 is connected with the input of power set 3, resistive heater 4 respectively; The input of described microcomputerized controller 5 is connected with the outfan of power control chip 2, power set 4 respectively.
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 worked for relay, and another kind is available to the 12v voltage of MCU, it is ensured 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, 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, two-way optocoupler is controlled, and two-way optocoupler controls controllable silicon, and then controllable silicon realizes motor is inputted the control of break-make again. This module is designed by the characteristic of linear transformer, namely the output voltage of transformator is linear with load, when motor is absent from, the approximate zero load of linear transformer, voltage is at more than 24v, Zener diode will reverse-conducting, On current makes the optocoupler in this module turn on, produce 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 and 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 and 5v voltage stabilizing obtained is turned on by Q4, owing to power pack provides constant current, lessens system power dissipation when dropping under voltage. 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. Having U2 in N/R situation to produce the different MCU that feeds back signal at motor and realize the detection to motor, when detecting motor exception, LED glimmers 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 namely during revolution, heat-generating disc does not work.
Above disclosed it is 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 without departing from the scope of technical scheme, when available above-mentioned disclosed technology contents makes the Equivalent embodiments changing or being modified to equivalent variations a little, according to the equivalent variations that the present patent application the scope of the claims is made, still belong to the scope that the present invention contains.
