Perception circuit 80 is connected node N1, N2 separately, and its effect is to judge to comprise whether the DC circuit of heater 30 is paths, promptly judges whether to heater 30 input power supplys.In order to reach above-mentioned judgement, perception circuit 80 uses connecting line 80a, 80b to be connected separately on node N1, the N2.Be assemblied on the control panel 9 that microcomputer 90 is installed because of perception circuit 80, this connecting line 80a, 80b need to carry out winding displacement along the inner space between cylinder 10 and the fuselage cover 3 or the medial surface of fuselage cover 3.
Be described in detail as follows more, perception circuit 80 judges according to ON/OFF (on/off) action of the 1st and the 2nd thermostat TS1, the TS2 that move along with the temperature of heater 30 or air whether power supply is input to heater 30.Though, also can control to the input of the power supply of heater 30 according to switch SW, but this switch SW is moved under the control of microcomputer 90, so when microcomputer 90 is in the state of " opening (on) " in switch SW, confirm the power supply input state according to the signal that obtains from perception circuit 80.When this switch SW was in the state of " close (off) " by the control of microcomputer 90, microcomputer 90 was not considered the signal that obtains from perception circuit 80.
Perception circuit 80 inputs to microcomputer 90 to different separately signals according to this power supply input state, makes microcomputer 90 can confirm the power supply input state of heater 30.The input of this perception circuit 80 is different with Fig. 5, can be connected between the 1st thermostat TS1 and the conventional power supply separately, between heater 30 and the switch SW.In the series circuit that forms by conventional power supply, the 1st and the 2nd thermostat TS1, TS2, heater 30 and switch SW, input along with conventional power supply, perception circuit 80 can more clearly be discerned the potential difference at heater 30 two ends, so it always is connected the position that can perception comprises the potential difference of heater 30 parts.
Microcomputer 90 is as above narration basically, according to instruction control heater 30, switch SW, the motor 72 such as use by input part 9a input, controls blowing fan 43 by control motor 72, carries out the oven dry action with this.In addition, microcomputer 90 possesses the function of the storage part (not shown) of storage control algorithm, and this storage part can use for example EEPROM.
Microcomputer 90 and perception circuit 80 are assemblied in the back of above-mentioned control panel 9.
In addition, microcomputer 90 is judged the power supply input of the 1st and the 2nd thermostat TS1, TS2 and the information of cutting off according to the perceptual signal that obtains from perception circuit 80.
Fig. 5 is the case study on implementation of the perception circuit of Fig. 4.As shown in Figure 5, perception circuit 80 be by input from the input voltage of node N1 just+the diode D1 of voltage; The input voltage of node N1 is carried out the resistance R 1 of step-down; Diode D2 and capacitor C1, they are used to prevent to be input to the interference of input voltage of input I1, the I2 of photoelectrical coupler PC; Resistance R 2 and capacitor C2 carry out the photoelectrical coupler PC of ON/OFF (on/off) along with input voltage; Voltage waveform, they are connected the output 01 of photoelectrical coupler PC, and according to the ON/OFF (on/off) of photoelectrical coupler PC, provide DC voltage to microcomputer 90, the mutual difference that reference voltage V ref is following.These reference voltage V ref is equipped with in the circuit of microcomputer 90, the driving voltage of the microcomputer 90 that uses, omitted the explanation of the voltage input part of this reference voltage V of relevant generation ref, for the generation of relevant these reference voltage V ref, the people that know this TECHNICAL FIELD OF THE INVENTION are very simple technology.
Particularly, conventional power supply is the situation of AC240V for example, and the potential difference between node N1 and the N2 is about 240V, so when this voltage directly inputs to photoelectrical coupler PC, photoelectrical coupler PC may damage, so resistance R 1 can be depressured to input voltage in tens of volts.
And, when photoelectrical coupler PC has potential difference between node N1 and N2, promptly in order to import power supplys to heater 30, when the 1st and the 2nd thermostat TS1, TS2 are converted to " opening (on) ", the voltage of corresponding this potential difference is imported into input, so voltage is alternating voltage, and inner photodiode is along with the cycle of this voltage is luminous, this moment, the transistor of light absorbing part carried out ON/OFF (on/off) thereupon, imported square wave in the microcomputer 90.When not having potential difference between node N1 and the N2, promptly in order not import power supplys to heater 30, when the 1st or the 2nd thermostat TS1, TS2 are in " closing (off) ", the input of perception circuit 80 is idiostatic, inner photodiode can be not luminous, the transistor of light absorbing part is converted to (off) state of closing, and continues the DC voltage waveform of input near reference voltage V ref this moment in the microcomputer 90.
Fig. 6 and Fig. 7 are the output waveform charts of perception circuit.As shown in Figure 6, the the 1st and the 2nd thermostat TS1, TS2 are when the state of " opening (on) ", the conventional AC power of input in the heater 30, therefore after node N1 and N2 go up the voltage difference of corresponding this conventional power supply size of input, cause that according to this voltage difference photoelectrical coupler PC is converted to " opening (on) ", because of the cycle of alternating voltage matching convention power supply, photoelectrical coupler PC carries out ON/OFF (on/off) repeatedly, the input square wave littler than reference voltage V ref in the microcomputer 90.
As shown in Figure 7, when the 1st or the 2nd thermostat TS1, TS2 are in the state of " closing (off) ", not to heater 30 supply powers, node N1 and N2 are in same potential, make photoelectrical coupler PC continue to be in the state of " closing (off) ", have this moment near the DC voltage of reference voltage V ref for example the high signal be input in the microcomputer 90.
Thereupon, microcomputer 90 waveforms according to the DC voltage of being imported can be calculated closing the 30 power supply times of (off) cut-out heater that state caused by the 1st and the 2nd thermostat TS1, TS2.
Fig. 8 is ON/OFF (on/off) chart of microcomputer identification.Fig. 8 is ON/OFF (on/off) chart of discerning in the microcomputer of Fig. 5.Among Fig. 8, R is meant the diameter of blast pipe 50, and its digital unit is an inch (inch).Promptly, when diameter is R (2.0), R (2.3), R (2.625), R (2.88), R (3.0), according to signal, show the ON/OFF (on/off) of the power supply input state that inputs to heater 30 that microcomputer 90 is discerned as Fig. 6 and Fig. 7 perception circuit 80.Diameter is wide more, and the state chocking-up degree of gas channel is weak more, and diameter is narrow more, and the state blocked state of gas channel is strong more.
In order to determine the blocked state of gas channel, adopt to begin to calculate and confirm the method for ON/OFF (on/off) duty ratio of power supply input.In this case study on implementation, can use " opening (on) " duty ratio x '/y ' and " closing (off) " duty ratio z '/y ' simultaneously, also only to use one of them.Describe closing (off) duty ratio z '/y ' below.
At first, pass (off) duty ratio of R (2.0) is that 0.48 to open (on) duty ratio be 0.52, pass (off) duty ratio of R (2.3) is that 0.32 to open (on) duty ratio be 0.68, pass (off) duty ratio of R (2.625) is that 0.26 pass (off) duty ratio is 0.74, pass (off) duty ratio of R (2.88) is that 0.13 to open (on) duty ratio be 0.87, and pass (off) duty ratio of R (3.0) is that 0 to open (on) duty ratio be 1.That is, can judge diameter and reduce more, closing (off) duty ratio increases more, opens (on) duty ratio comparatively speaking and reduces more.So microcomputer 90 closes (off) duty ratio by calculating, the chocking-up degree that can judge present gas channel is the obstruction of cotton linters filter 41 or the blocked state of blast pipe 50 particularly.These experimental results can be organized into as following table 1.
[table 1]
| Close the off duty ratio | Chocking-up degree | Blocking portion |
| 0～0.30 | - | - |
| 0.30～0.45 | Down | Cotton linters filter |
| 0.45～0.60 | Middle moderate | That cotton linters filter stops up is serious/and the blast pipe chocking-up degree is a moderate |
| 0.60～ | Go up serious | Blast pipe |
Microcomputer 90 storages comprise the block information of the gas channel of the chocking-up degree that is formed by above-mentioned ON/OFF (on/off) duty ratio etc.These store the drying work number of times of corresponding dryer.Particularly, dryer 1 is initial when installing or installing owing to reasons such as removals of home again, the final chocking-up degree of microcomputer 90 storage gas channels, after this initial chocking-up degree of more correctly storing blast pipe 50 appends storage along with the relevant chocking-up degree of drying work operation.For example, the initial chocking-up degree of microcomputer 90 storage is D0, chocking-up degree afterwards be with D1, D2 ..., Dn-1, Dn the storage.
Fig. 9 a and 9b are the demonstration embodiment of display unit.
Shown in Fig. 9 a, display part 9a is made up of single gear L1., for example, close duty ratio and be under the 0.45 high situation than single obstruction value in current chocking-up degree, display part 9a gear L1 is bright lamp, and can allow gear L1 flicker.
Shown in Fig. 9 b, display part 9b is made of continuously a plurality of gear L1 '～L3 '.Display part 9b simultaneously or in order gear L1 '～L3 ' is carried out bright lamp and light-off also can make particular gears L1 '～L3 ' flicker.
Among Fig. 9 a and the 9b, the chocking-up degree of gas channel just often, the situation that does not promptly have displayable chocking-up degree, gear L1～L3, L1 '～L3 ' of display part 9b all extinguishes, therefore, the user is difficult to confirm whether this display part 9b runs well, and has shown the chocking-up degree information of gas channel.That is, the particular gears L1 of display part 9b～L3, L1 '～when L3 ' was out of order, the user thought that shown chocking-up degree is the actual blockage degree by mistake.So, need provide display part 9b operate as normal whether information to the user.
Figure 10 is the precedence diagram of display packing of the dryer of this invention.
Be described in detail as follows, in stage S11, after microcomputer 90 judges whether to import conventional power supply, will when the conventional power supply of input, will carry out stage S12.
In stage S12, microcomputer 90 makes gear L1L1 '～L3 ' flicker of display part 9b, allows the user can judge whether display part 9b is in normal operating conditions.All extinguish after these gears L1L1 '～L3 ' flicker.
In stage S13, the chocking-up degree information that microcomputer 90 judges whether the gas channel that stored is the chocking-up degree or the blocked state of cotton linters filter 41 particularly.When if the chocking-up degree information of the gas channel that has stored is arranged, will carry out stage S14, if do not have, will carry out stage S15.
In stage S14, microcomputer 90 shows the chocking-up degree information of the gas channel that has stored by display part 9b.At this moment, display part 9b shows by bright lamp and the pairing gear number of chocking-up degree L1～L3.With stage S12 linkage display chocking-up degree, the user is shown the display part 9b content of stage S14 by after the guiding of stage S12 sense of vision, and therefore, the user can more clearly discern chocking-up degree.
In stage S15, microcomputer 90 by the instruction that input part 9a input drying work begins, when perhaps entering the drying work order of regulation algorithm, will carry out stage S16 the user.
In stage S16, microcomputer 90 is according to the signal of said sensed circuit 80, judge the ON/OFF (on/off) of temperature controlling unit, calculate relevant ON/OFF (on/off) duty ratio thereupon after, judge that degree or blocked state are carried out in the chocking-up degree or the obstruction of gas channel.
In stage S17, when the chocking-up degree of being judged when microcomputer 90 is even more serious than the chocking-up degree of current demonstration, associated chocking-up degree is shown by display part 9b, show that before when not having chocking-up degree, the chocking-up degree of having judged shows by display part 9b.
In stage S18, microcomputer 90 judges whether drying work finishes.If drying work does not finish, will carry out stage S16, continue to judge the chocking-up degree of gas channel.If the end drying work will be carried out stage S19.
