The the 1st and the 2nd thermostat TS1, TS2 are a kind of temperature variant adjusting portions.It is installed in the side of heater 30 or nearby, produce reaction along with the temperature of the air of the temperature of heater 30 or heater 30 heating, the overtemperature that does not reach regulation is kept the state of " opening (on) " before, convert the state of " closing (off) " when surpassing overtemperature to, and cut off the conventional power supply that is input to heater 30.What particularly point out is, in order to protect the 1st thermostat TS1 and the 2nd thermostat TS2, in case when being converted to the state of " closing (off) ", can not return to the state of " holding (on) ".For example, the 1st and the 2nd thermostat TS1, suction passage 20 that TS2 is installed in to be connected with heater 30.
In addition, switch SW is made of the same element of relay, and when " opening (on) " of microcomputer 90, " opening (the on) " state of keeping is carried out in control oven dry, during according to " closing (off) " of microcomputer 90, controls it and keeps " closing (off) " state.
In addition, after the control instruction relevant that input part 9a accepts user input, input to microcomputer 90 with oven dry operation etc.
In addition, display part 9b demonstration is graded by the input of the oven dry operation of user's input, the chocking-up degree of advancing degree, remaining time and gas channel, the choking portion of oven dry operation.This display part can use LED element or LCD element etc. to embody.Wherein gas channel comprises suction passage 20, cylinder 10 inside, passing away 40 and outside blast pipe 50, particularly comprises cotton linters filter 41 and outside blast pipe 50 in the passing away 40.
In addition, display part 9b can be showing after each self-separation of chocking-up degree of the chocking-up degree of cotton linters filter 41 and blast pipe 50.
In order to show these chocking-up degrees, display part 9b is made of a plurality of gears that can show the chocking-up degree more than 2 stages at least, and shows chocking-up degree by the bright lamp and the light-off of a plurality of gears.
Perception loop 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 loop 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 loop 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 loop 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 loop 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 loop 80.
Perception loop 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 in this perception loop 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, the potential difference at heater 30 two ends can be more clearly discerned in perception loop 80, so it always is connected the position that can perception comprises the potential difference of heater 30 parts.
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 loop 80.
Fig. 5 is the embodiment in the perception loop of Fig. 4.As shown in Figure 5, perception loop 80 comprises from the input voltage of node N1 the just diode D1 of (+) voltage of input; 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 voltage waveform of ON/OFF (on/off) photoelectrical coupler PC along with input voltage, 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.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.Photoelectrical coupler PC also comprises earth terminal 02.
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 in perception loop 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 in perception loop.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, the the 1st or the 2nd thermostat TS1, when TS2 is 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 the DC voltage (for example high signal) near reference voltage V ref to be input in the microcomputer 90 this moment.
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).That is, when diameter is R (2.0), R (2.3), R (2.625), R (2.88), R (3.0),, show the ON/OFF (on/off) of the power supply input state that inputs to heater 30 that microcomputer 90 is discerned according to signal as Fig. 6 and Fig. 7 perception loop 80.Diameter is wide more, and the state of gas channel (chocking-up degree) is weak more, and diameter is narrow more, and the state of gas channel (blocked state) 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 embodiment, can use out (on) duty ratio (x '/y ') simultaneously and close (off) duty ratio (z '/y '), 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 0.48 (opening (on) duty ratio is 0.52), pass (off) duty ratio of R (2.3) is 0.32 (opening (on) duty ratio is 0.68), pass (off) duty ratio of R (2.625) is 0.26 (closing (off) duty ratio is 0.74), pass (off) duty ratio of R (2.88) is 0.13 (opening (on) duty ratio is 0.87), and pass (off) duty ratio of R (3.0) is 0 (opening (on) duty ratio is 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, and can judge the chocking-up degree (the particularly blocked state of the obstruction of cotton linters filter 41 or blast pipe 50) of present gas channel.These experimental results can be organized into as following table 1.
[table 1]
| Close (off) duty ratio | Chocking-up degree | Blocking portion |
| 0～0.30 | - | - |
| 0.30～0.45 | (weak) down | Cotton linters filter |
| 0.45～0.60 | In (moderate) | Cotton linters filter (stopping up serious)/blast pipe (chocking-up degree is a moderate) |
| 0.60~ | Go up (seriously) | Blast pipe |
Fig. 9 a and 9b are the demonstration embodiment of display unit.
Illustrated in Fig. 9 a, display part 9b is formed by a plurality of gear L1～L4 of certain intervals distance.Display part 9b simultaneously or in order gear L1～L4 is carried out bright lamp and light-off also can make particular gears L1～L4 glimmer.
Illustrated in Fig. 9 b, display part 9b is disposed by a plurality of gear L1 '～L4 ' to form continuously.Display part 9b simultaneously or in order gear L1 '～L4 ' is carried out bright lamp and light-off also can make particular gears L1 '～L4 ' flicker.
Among Fig. 9 a and the 9b, the chocking-up degree of gas channel does not just often promptly have the situation of displayable chocking-up degree, and gear L1～L4, L1 '～L4 ' of display part 9b all extinguishes, therefore, the user is difficult to confirm whether this display part 9b runs well has shown the chocking-up degree of gas channel.That is, the particular gears L1 of display part 9b～L4, L1 '～when L4 ' 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.
Following Figure 10 to 12 is the situations that are applicable to the display part 9b of Fig. 9 a.
