Description
Technical field
The present invention relates to a kind of insulating box, and in particular to a kind of simple type domestic insulating box.
Background technology
In China Midwest, the custom of sweet wine is all made of glutinous rice to winter every household, can be exactly the bad grasp of temperature in glutinous rice fermentation, be supplied currently without simply and easily Domestic thermostatic case.
Also there is insulating box in the market, but the practical custom of insulating box is external introduction, each manufacturer is all directed to booming income crowd, and prevailing price positioning is higher, is not suitable for numerous urban residents and uses, can not also be popularized in numerous urban residents and ordinarily resident.
The content of the invention
The present invention provides a kind of simple type domestic insulating box, its low cost, simple and convenient, suitable for numerous urban residents and ordinarily resident.
The technology of the present invention solution is：
A kind of simple type domestic insulating box, including container, circuit and working power, it is characterised in that：The circuit includes thermistor, thermoregulator, amplifier, relay, the heater being sequentially connected；Working power includes transformer, rectifier, wave filter, voltage-stablizer, the power indicator being sequentially connected, voltage-stablizer is also connected with amplifier, the equipment has stable work in work, temperature control regulation is simple, temperature control accuracy is high, small volume is easy to use, it is cheap the advantages that, suitably in society generalization.
Preferably, a kind of simple type domestic insulating box, the thermoregulator are adjusted for potentiometer.
Preferably, a kind of simple type domestic insulating box, described amplifier are the compound composition of C9011, C9013 triode.
Preferably, a kind of simple type domestic insulating box, described relay are JQX-13F, and heater strip is electrical blanket silk.
Preferably, a kind of simple type domestic insulating box, described transformer is 3W outputs 15V, rectifier is 4 1N4001 diodes, wave filter is 470 μ F/25V electrochemical capacitors, voltage-stablizer is three terminal regulator 7812, power indicator is red LED diode.
Preferably, a kind of simple type domestic insulating box, described container innner and outer face centre are provided with heat insulation foam.
Preferably, a kind of simple type domestic insulating box, described container are the container that the compacting of glass sheetmetal is made, and can receive high 12 ㎜ of the ㎜ of bore 35 basin body.
Brief description of the drawings
Fig. 1 is electric elements connection diagram of the present invention.
Embodiment
Referring to Fig. 1, a kind of simple type domestic insulating box, including container, circuit and working power, it is characterised in that：The circuit includes thermistor, thermoregulator, amplifier, relay, the heater being sequentially connected；Working power includes transformer, rectifier, wave filter, voltage-stablizer, the power indicator being sequentially connected, voltage-stablizer connection amplifier, and the equipment has stable work in work, temperature control regulation is simple, temperature control accuracy is high, and small volume is easy to use, it is cheap the advantages that.
Element selects, thermoregulator is adjusted from potentiometer, amplifier selects the compound composition of C9011, C9013, relay selects JQX-13F, heater strip selects electrical blanket silk, Transformer Selection 3W outputs 15V, rectifier select red LED diode from 470 μ F/25V electrochemical capacitors, voltage-stablizer from 4 1N4001 diodes, wave filter from three terminal regulator 7812, power indicator, heat insulation foam is provided among the container innner and outer face of insulating box, the container that container is made using the compacting of glass sheetmetal, high 12 ㎜ of the ㎜ of bore 35 basin body can be received.
The present invention basic ideas be：The signal of temperature change in probe acquisition casing is made of thermistor, amplifying the voltage signal of temperature change with compound transistor makes relay work, and to control heater strip to be heated or not heated, working power uses transformer pressure-reducing（220V AC voltage is dropped to the 15V alternating voltages of needs）Bridge rectifier is formed using 4 diodes, alternating current is become direct current, again through capacitor filtering, 7812 three terminal regulator voltage stabilizings turn into stable 12V DC electricity, powered for control element, the operating voltage that compound transistor amplifier access adjuster can be exported with the thermistor inside regulating thermostatic case（Its resistance value is in different size by different temperature for thermistor, and its output-input voltage is just different in circuit）, so as to reach the purpose for setting control constant temperature the temperature inside the box height.
The container of simple type domestic insulating box is made using the compacting of glass sheetmetal, can receive high 12 ㎜ of the ㎜ of bore 35 pottery pot, and 60X60X40 ㎜ square configuration is made in outside, and it is warming to add heat insulation foam among the inside and outside face of container.
