Subregion is that the arranged distribution position of heater element is divided into several regions; That whole heat drying process is cut into several periods at times.
Now take timing 4h, three regions, three periods is example explanation:
Decontaminating apparatus start by set date is started working and is limited to the temperature rise period to being warmed up on interior design temperature, and this temperature-rise period takes 20 minutes.Thereafter to being the first period of insulation between timing working 1 hour; After the first insulation period, to timing working, it was the second insulation period between 2 hours; After the second insulation period, to regularly ending up being the 3rd, be incubated the period.Fig. 2 is the division schematic diagram in three regions of the present embodiment: there are 5 heater element Rfz1 a-quadrant, and there are 8 heater element Rfz2 in B region, and there are 12 heater element Rfz3 in C region.More than arranging is, generate heat uniform principle uniform based on heater element.The heater element of a-quadrant is minimum is that waste heat is maximum because a-quadrant is operated in the first period of insulation.
Subregion, replace at times, the heating of intersection, superposition is a kind of brand-new Intelligent heating.The more detailed rules and regulations heating-up temperature that region, period divide is more constant, and meanwhile, the combination of region, period optionally can combination in any.
Ultraviolet light pipe 10, electric ballast AP1, audion VT form sterilisation circuit 30, are controlled by the PC3 mouth of single-chip microcomputer U1.During PC3 mouth high level, electric ballast AP1 lights ultraviolet light pipe 10, sends the direct sterilizing of ultraviolet light.Safety switch 13 outputs signal to the PD3 mouth of single-chip microcomputer U1 by inverter ic, realize the conducting of the power supply of ultraviolet light pipe 10 or cut-out.
In addition, for the ease of knowing the electric weight of dry timing and detection sonifer, display circuit 32 and battery detection circuit 34 can also be set.
Display circuit 32 adopts lattice lcd modular LCDs, can display text, symbol and figure.A, time showing: timing setting time, minute 2h, 4h, 6h; Start by set date constantly, is made for 24 hours; The instant time, 24 hours systems, by increasing progressively second.B, temperature show: real-time temperature.C, electric weight show: when battery figure is space, word shows battery failure; When battery figure has lattice, word shows owes electricity; When battery figure has two lattice, word shows that electric weight is not enough; When battery electric quantity is the full lattice of three lattice, word shows that electric weight is sufficient;
The height that battery detection circuit 34 utilizes the analog-digital converter ADC of ATmega8 single-chip microcomputer U1 inside to detect cell voltage judges the quality of battery.Single chip computer AT mega8 provides the ADC of 6 road successive approximations, and wherein, these 4 passages of ADC0-ADC3 provide the conversion accuracy of 10, and ADC4, two passages of ADC5 only provide the conversion accuracy of 8.This circuit utilizes ADC0 to detect the height of voltage.During test, as long as battery is placed in the detecting groove 36 of housing 2, push-tight makes it to contact well with the pole piece (not shown) in detecting groove 36, pole piece has positive pole, negative pole, the positive pole of pole piece is connected with the PC0 mouth of single-chip microcomputer U1, minus earth, the i.e. quality of known battery.Testing result is shown with figure and word by LCD, minute 4 kinds of states: when battery figure is space, word shows battery failure; When battery figure has lattice, word shows owes electricity; When battery figure has two lattice, word shows that electric weight is not enough; When battery electric quantity is the full lattice of three lattice, word shows that electric weight is sufficient.
Work process:
Sonifer is placed on printing opacity dividing plate 8, switches on power, and system powers on and automatically resets, and initializes.Press continuously SB1 timing and select button 2 times, start by set date, LCD Displaying timer time 4h, start by set date moment xx:xx and instant time xx:xx are by increasing progressively second.Simultaneously, DS18B20 temperature sensor collecting temperature data also send data to single-chip microcomputer U1 from bus and process through single-chip microcomputer U1, with preset temperature comparison, result is well below lower threshold, start priority routine, single-chip microcomputer PB1 mouth, PB2 mouth, PB3 output low level, drive all thermals treatment zone of drying circuit 26 heat temperature raising simultaneously, until the temperature data that DS18B20 collects has reached while presetting temperature upper limit threshold value, single-chip microcomputer U1 sends instruction, the B thermal treatment zone and the C thermal treatment zone that PB2 mouth, PB3 mouth output high level turn-off drying circuit 26.Complete machine entered for the first insulation period, only by the A thermal treatment zone, compensated heating, to keep temperature constant.Enter insulation the second period single-chip microcomputer PB1 mouth output high level and turn-off the A thermal treatment zone, PB3 mouth output low level is opened C thermal treatment zone heating and thermal insulation.Enter insulation the 3rd period single-chip microcomputer PB3 mouth output high level and turn-off the C thermal treatment zone, PB1 mouth, PB2 mouth output low level open the A thermal treatment zone and the supplementary heating of the B thermal treatment zone until regularly 4h finish.Simultaneously, set in heating overall process and carry out re-pasteurization sterilization, entering the first insulation period and second insulation automatic startup work during the period respectively, ultraviolet light pipe 10 sends the ultraviolet light that wavelength is 200-280nm, the ultraviolet light producing can and reflex to sonifer through the direct radiation of specular layer 12, irradiation intensity and irradiation range are large, thorough in sterilization, automatic distinguishing after each ten minutes.In addition, when opening cap 4, safety switch 13 can be passed to single-chip microcomputer U1 by signal, and single-chip microcomputer U1 proceeds to the power supply that urgent interrupt routine cuts off ultraviolet light pipe 10, and ultraviolet light pipe 10 extinguishes, thus the safety of the user that adequately protects.
If detected in heat drying process when presetting temperature, can automatically interrupt original insulation program and preferentially enter supplementary heating program, until be warming up to while presetting temperature, automatically exit preferential supplementary heating program recovery and continue insulation program.When detecting when presetting temperature, can interrupt insulation program and preferentially enter the emergency procedure that cuts off heater element power supply, until temperature, be down to and can automatically exit emergency procedure while presetting temperature and recover to continue insulation program.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content in description, must determine technical scope according to claim scope.
