With reference to Fig. 4, the workflow with dryer of multiple protection functions described in the utility model is:

1. connection power supply, power supply is linked into the power input AC of protection control circuit as shown in Figure 4, by regulator rectifier circuit, the voltage vcc that output is used for the protection control circuit (wherein symbol something in common such as institute's label L 1, TZ and ZE among the figure represent that circuit communicates with each other);

2. press switch key S1, trigger 1 low level signal at the PA1 of main control chip 1 pin, start main control chip 1, main control chip 1 sends signal to display driver chip 6, display driver chip 6 control display floaters 5 show time figure 00:00, finish initial work;

3. press timer button S2, trigger 1 low level signal at the PA2 of main control chip 1 pin, whenever can increase by 15 minutes by the one action time, maximum setting-up time can be 180 minutes, as desire to reset the working time, and continuing to pin timer button S2, the duration can be chosen as for 5 seconds, main control chip 1 recognizes this signal will send signal to display driver chip 6, and display driver chip 6 control display floaters 5 show time figure 00:00 again;

4. by conversion keys S3 is set, trigger 1 low level signal at the PA2 of main control chip 1 pin,

During 1. by one time, the duty with dryer of multiple protection functions is low wind speed, nothing temperature, and the corresponding form that display driver chip 6 control display floaters 5 are shown shown in Fig. 5 a;

During 2. again by one time, the duty with dryer of multiple protection functions is high wind speed, does not have temperature, and the corresponding form that display driver chip 6 control display floaters 5 are shown shown in Fig. 5 b;

During 3. again by one time, the duty with dryer of multiple protection functions is low wind speed, low temperature, and the corresponding form that display driver chip 6 control display floaters 5 are shown shown in Fig. 5 c;

During 4. again by one time, the duty with dryer of multiple protection functions is high wind speed, low temperature, and the corresponding form that display driver chip 6 control display floaters 5 are shown shown in Fig. 5 d;

During 5. again by one time, the duty with dryer of multiple protection functions is high wind speed, high temperature, and the corresponding form that display driver chip 6 control display floaters 5 are shown shown in Fig. 5 e.

Wherein, main control chip 1 is not exported the triggering signal of triggering signal or output certain frequency and dutycycle to the control end 321 of gauge tap element 32 by its PC0 pin, control heater 35 is not worked, or is in the low-temperature working state, or is in the duty of high temperature; Main control chip 1, is controlled motor 43 low speed or is run up low wind speed of generation or high wind speed to the control end 411 output certain frequencies of gauge tap element 41 and the triggering signal of dutycycle by its PC1 pin.Because the selection that described dryer with multiple protection functions has multiple mode of operation; so can select different mode of operations and set the different working times at different linings, dissimilar clothings; protect clothing effectively, reach drying effect preferably.

At first, when the duty of selecting is low temperature, thermostat probe 311 can be when the dryer temperature inside with multiple protection functions reaches uniform temperature (can for about 38 degree), main control chip 1 will be automatically adjusted the power output of heaters 35 by gauge tap element 31, and the dryer temperature inside that keeps having multiple protection functions remains on uniform temperature constant temperature work (can for about 38 degree); When the duty of selecting is high temperature; thermostat probe 311 can be when the dryer temperature inside with multiple protection functions reaches uniform temperature (can for about 50 degree); main control chip 1 will be automatically adjusted the power output of heaters 35 by gauge tap element 31, and the dryer temperature inside that keeps having multiple protection functions remains on uniform temperature constant temperature work (can for about 50 degree).This kind constant temperature function; the dryer temperature inside that assurance has multiple protection functions can not raise always; effectively the protection clothing can be not bad by baking; when if thermostat probe 311 can not be worked; when the dryer temperature inside with multiple protection functions reaches higher temperature (can be 70 degree), limit probe 312 can send signal to main control chip 1 by the PB3 pin of main control chip 1; main control chip 1 will stop ongoing running status, wait for that the user starts shooting again.

Secondly, as shown in Figure 4, because the mode that adopts heater 35 to connect with limit fusing thermal protector 33 and thermostat 34, when motor 43 occur not changeing or the air inlet of body, situation that air outlet is blocked by clothing under, make temperature around the heater 35 reach 120 when spending, thermostat 34 can automatic disconnections, treat that temperature reduces after, thermostat 34 can automatic adhesive; When if thermostat 34 is inoperative, the temperature around the heater 35 reaches 192 when spending, and limit fusing thermal protector 33 will disconnect.

Moreover, as shown in Figure 4 because the mode that adopts motor 43 connect with thermal protector 42, when the temperature rise of motor 43 reaches 120, motor 43 autostops, treat that motor 43 cools off after, thermal protector 42 is understood automatic adhesive.

At last; owing to adopted ball switch S0 as shown in Figure 4; when working, described dryer with multiple protection functions slips; ball switch S0 will disconnect; the I/O pin PA3 of main control chip will produce 1 high level signal, and main control chip 1 will be controlled the duty that termination is moving this moment.

Described heater 35 adopts nonmetal heating unit, and adopts interior the circulation to advance to dry mode of operation fully, with the hot air circulate utilization of working region, has improved the operating efficiency of the dryer with multiple protection functions, has reduced energy consumption.
