The specific embodiment
Example to forced-air heating device of the present invention describes in conjunction with drawing below.Fig. 1 is the formation schematic diagram of the forced-air heating device of this example.Fig. 2 be this example the forced-air heating device report function declaration figure.
Forced-air heating device as shown in Figure 1 has burner 10, combustion fans 20, room air the 1st conveyance conduit 31 that the work by combustion fans 20 is inhaled into from air entry 311 as combustion air, the work of room air by identical combustion fans 20 is inhaled into and mixes mutually from air outlet 322 with the burning and gas-exhausting of burner 0 from air entry 321 delivers to the 2nd outside conveyance conduit 32 as warm braw, can set the control module 50 of the operation panel 40 of heating temperature etc. and 10 burnings of control burner etc.
Be provided with at air entry 311,321 places of the 1st, the 2nd conveyance conduit 31,32 and prevent that dust etc. from entering the filter 330 of the 1st, the 2nd conveyance conduit 31,32.Near the air entry 321 of the 2nd conveyance conduit 32, be provided with temperature sensor 34.Be provided with by gear motor 35 drive and movable shutters 36 that can regulate air outlet 322 switching degree at air outlet 322 places of the 2nd conveyance conduit 32.
Rising degree Δ Θ/Δ t (＞0) of the room temperature Θ that the 1st determinator 51 is measured according to temperature sensor 34 and careat size A is measured.The 2nd determinator 52 is according to the switching degree of gas control valve 113 and the accumulation quantity combusted Q of burner 10 is measured.Decline degree Δ Θ/Δ t (＜0) of the room temperature Θ that the 3rd determinator 53 is measured according to temperature sensor 34 and indoor ventilation volume v is measured.Memory storage 54 is made of RAM, ROM etc., the careat size A that the 1st determinator is measured or described later give decide critical value c and remember preservation in, the accumulation quantity combusted Q by the measured burner 10 of the 2nd determinator 52 is upgraded gradually and is remembered preservation.
Device for informing 56 comprise as inscape report lamp 43, the judgement parameter k that is calculated by calculation element 55 is in by giving of preserving of memory save set 54 memories and decides critical value c when above, makes to report lamp 43 and light and make reporting of must taking a breath.
Function with regard to the forced-air heating device describes in conjunction with Fig. 2 below.
At first, when with the running button 41 of operation panel 40 when OFF is set as ON, combustion fans 20 is started working by control module 50, ignitor 12 is lighted a fire, and opens gas solenoid valve 112, the switching degree of adjustments of gas control valve 113.Thus, in the 1st conveyance conduit 31, make supply with road 11 gas supplied and room air from air entry 311 inspirations mix mutually from gas after, supplied burner 10 confessions its take fire (s1).Then in the 2nd conveyance conduit 32, the room air that sucks from air entry 321 is mixed mutually with the burning and gas-exhausting of burner 10 be sent to indoor from air outlet 322 as warm braw.In addition, room temperature Θ is in rising gradually, and is consistent for the temperature that makes the room temperature Θ that measured by temperature sensor 34 and setting button 42 by operation panel 40 set, and controls the switching degree of gas control valves 113 and the rotating speed of combustion fans 20 by control module 50.
After the burning from burner 10 begins through 1 minute, rising degree Δ Θ/Δ t of the room temperature Θ that in 3 minutes, records according to temperature sensor 34, and memory is stored in set algorithm in the memory storage 54 or the corresponding relation tables of data of rising degree Δ Θ/Δ t and careat A etc., and the careat A that is placed with the forced-air heating device by 51 pairs of determinators measures (s2).A is big more for rising degree Δ Θ/more little then careat of Δ t.At this moment, 54 pairs of careats of being measured of memory storage are remembered preservation.
Then, after burner 10 burning beginning, the 2nd determinator 52 begins to measure (s3) according to the switching degree of gas control valve 113 to accumulation quantity combusted Q.At this moment, the accumulation quantity combusted Q that measured of 54 pairs the 2nd determinators 52 of memory storage upgrades gradually and remembers preservation.
Then, calculation element 55 by memory is stored in the memory storage 54 accumulation quantity combusted Q divided by careat A calculate (s4) judge parameter k (=Q/A).
Then, whether the 3rd determinator 53 is to bear to judge and have or not indoor air-changing (s5) according to change degree Δ Θ/Δ t of room temperature Θ.
When being judged as indoor the ventilation (YES of s5), the 1st correcting device 551 carries out the 1st minimizing correction (s6) according to decline degree Δ Θ/Δ t (＜0) of room temperature Θ to judging parameter k.For example, decline degree Δ Θ/Δ t less than-3.0 (℃/min) under the situation, look indoor quilt and fully take a breath and unnecessaryly fully take a breath again, k is reduced being modified to 0.In addition, decline degree Δ Θ/Δ t-3.0 (℃/min) more than-2.0 (℃/min) less than situation under, look indoor taken a breath, the necessity of ventilation weakens, and k is reduced correction with 0.5 times of ground.In addition, decline degree Δ Θ/Δ t-2.0 (℃/min) more than 0 (℃/min) less than situation under, it is insufficient to look indoor air-changing, is necessary the processing of taking a breath again, and k is not reduced correction.This 1st reduces correction is, when room temperature Θ descends big more judgement parameter k also more by minimizing correction significantly.
Then, the 1st determinator 51 judges according to the output of thermocouple 13 whether the burning of burner 10 stops (s7).
When being judged as burner 10 burning when being stopped (YES of s7), timer 57 picks up counting.And the 2nd correcting device 552 carries out the 2nd minimizing correction (s8) according to the timing of timer 57 to judging parameter k.After the burning of burner 10 stops, though the not reduction of the necessity of ventilation, along with time lapse, indoor CO
2Deng concentration also reduce gradually thereupon, thereby according to the minimizing correction that this qualitative investigation is carried out the 2nd kind that weakens of ventilation necessity.That is, after the burning of burner 10 stops, will judging that parameter k keeps a period of time, reduce correction more gradually through behind the certain hour.
And, that the 56 pairs of calculation elements of device for informing calculate that (s4) go out, whether suitably reduce the parameter k that judges that revises (s6, s8) by the 1st, the 2nd correcting device 551,552 be that memory is stored in giving in the memory storage 54 and decides critical value c above (s9).
When judge judging that parameter k is giving when deciding more than the critical value c (YES of s9), device for informing 56 is lighted and is reported lamp 43, makes report (s10a) of indoor air-changing necessity.On the other hand, judge parameter k less than giving when deciding critical value c (NO of s9) when being judged as, device for informing 56 maintains to be reported state that lamp 43 do not light a lamp or the state of the lighting a lamp lamp of doing to disappear is handled (s10b).
Then, take out the attaching plug (not shown) from socket, as long as the "on" position of forced-air heating device is not disengaged (NO of s11), the processing of above-mentioned s3-s10 will be continued to carry out.
Adopt this forced-air heating device, promptly can obtain (s4 among Fig. 2) with respect to the simple process of the ratio of careat A as the accumulation quantity combusted Q of the judgement parameter k that reports the necessary judgment standard of ventilation by burner 10.Therefore, can be reduced to low spot by the cost that the computing function is required.And, judge that parameter k can reflect the variation of the quantity combusted of burner 10, when reaching to give, this judgements parameter k decides critical value c when above, report (s10a among Fig. 2) of the necessity of taking a breath.Therefore, can necessity of indoor air-changing be reported progressively holding on the indoor situation of change basis.
In addition, because indoor air-changing, the room temperature Θ that temperature sensor 34 records and thereupon descending is to judging that parameter k carries out the 1st and reduces and revise (s6 among Fig. 2).So, hang down the situation of also being reported necessary ventilation even also can avoid judging the necessity that parameter k is crossed calculates ventilation greatly effectively.
And the elapsed time after stopping according to the burning of burner 10 is to judging that parameter k carries out the 2nd and reduces and revise (s8 among Fig. 2).So, can avoid the following state of affairs to take place again, that is: burner k after burning stops, indoor also residual much CO in the regular hour
2, and at O
2The lower state of concentration ratio under, when burner 10 burns again,, do not report the necessary situation of ventilation even be necessary to take a breath owing to judge that parameter k is calculated too smallly yet.
In addition, in this example, though necessary the reporting of ventilation is to light a lamp and visually reported by reporting lamp 43,, in other example, ventilation is necessary reports also and can report by the sense of hearing of buzzer etc.
In this example, though what ventilation was necessary reports only according to judging that parameter k reports, but, in other example, device for informing 56 is not only to judge that parameter k is in to give to decide critical value c when above, and in the output of the thermocouple 13 that the fired state that detects burner 10 is detected less than giving when making the power value, also can make necessary the reporting of ventilation.
Adopt this other example, even do not decide more than the critical value c when judging that parameter k is not in to give, and the output of thermocouple 13 is in to give and makes below the power value, and burner 10 is detected under the burning unfavorable condition, also can be used as O
2Concentration is lower and report necessity of ventilation.Thus, even, also can report necessity of ventilation according to the output valve of thermocouple 13 just in case necessary when reporting cisco unity malfunction under the situation according to judging that parameter k takes a breath.
In this example, though according to room temperature rising degree Δ Θ/Δ t measuring cell inner area A, and according to careat A decision judgement parameter k (Q/A), again according to judging parameter k and giving the necessity of relatively reporting ventilation of deciding critical value c.But, as other example, also can come measuring cell inner volume V according to room temperature degree of rising Δ Θ/Δ t, parameter k is judged in decision according to chamber interior volume V
1(Q/V), again according to judging parameter k
1Decide critical value c with giving
1The necessity of relatively reporting ventilation.In addition, as another example, also can directly judge parameter k according to room temperature rising degree Δ Θ/Δ t decision
2(Q/ (Δ Θ/Δ t)) is again according to judging parameter k
2Decide critical value c with giving
2The necessity of relatively reporting ventilation.
