[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system for adjusting a combustion device such as a hot air heater or a hot water heater.
[0002]
[Prior art]
In a combustion apparatus such as a hot-air heater, the rotation speed of a fan that supplies combustion air to a burner is determined by applying a reference current related to data stored in data storage means such as an EEPROM to the fan. It is controlled to become. However, even if currents of the same value are energized according to the characteristics of the fans, the rotational speed differs for each fan. In this case, even if the reference current is supplied to the fan, the rotation speed does not reach the reference rotation speed, and there is a risk of causing a burner failure due to shortage of combustion air.
[0003]
Therefore, as disclosed in Japanese Patent Application Laid-Open No. 7-35348, a method of correcting the data related to the reference current stored in the data storage means in the hot air heater is considered. According to this method, after the reference current is supplied to the fan, the reference current to be supplied is corrected so that the rotation speed matches the reference rotation speed, and the data relating to the correction is stored in the data storage means. Retained. Thus, the data related to the reference current is corrected based on the correction data stored and held by the data storage means, and the fan is controlled to the reference rotation speed by energizing the corrected reference current. Since the variation in the fan characteristics is corrected in this way, it is possible to prevent the adverse effects such as the above-described combustion control failure such as the combustion failure of the burner.
[0004]
However, the inventor of the present application has found that the rotation speed of the fan varies not only due to the energized current but also due to the change in the ambient temperature of the fan during the correction. This is presumably because the fluid density around the fan changes in accordance with the ambient temperature, thereby changing the rotational load of the fan. Therefore, if only the individual characteristics of the fan are taken into account when correcting the reference current, the fan speed does not reach the reference speed even when the corrected reference current is applied, and burner combustion failure or the like is still caused. There was a risk of it occurring.
[0005]
[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide a system capable of adjusting the combustion device so as to eliminate the variation in the rotational speed due to the change in the ambient temperature of the fan in the combustion device.

Create The correction data created by the correction data creation means 6 is transmitted to the data communication means 26 of the hot air heater x by the adjustment side data communication means 1.
[0025]
The function of the system having the above-described configuration will be described with reference to FIGS. First, when the operation of the hot air heater x is turned on (FIG. 2 STEP 1), the burner 21 starts to burn and the fan 22 also starts to operate. The current supplied to the fan motor 22b at this time relates to the data stored and held in the EEPROM 24 corresponding to the minimum rotation speed (first speed) of the fan 22. Further, "ON data" is transmitted from the data communication means 26 to the adjustment-side data communication means 1 (left arrow (1) in FIG. 2), and thereby the timer 2 starts measuring the operating time of the hot air heater x (FIG. 2). 2 STEP2). When the measurement time of the timer 2 reaches the first predetermined time (YES in STEP 3 in FIG. 2), “request data” is transmitted from the adjustment-side data communication unit 1 to the data communication unit 26 to prompt the data transmission described below (FIG. 2). 2 right arrow (2)). Further, the rotational speed of the fan 22 is measured by the rotational speed measuring means 4 (STEP 4 in FIG. 2).
[0026]
In response to the request data, the data communication means 26 transmits data relating to the temperature measured by the thermistor 29 to the adjustment-side data communication means 1 (left arrow (3) in FIG. 2). Next, the computing means 5 computes the rotational speed difference between the minimum rotational speed and the measured rotational speed, and the temperature difference between the measured temperature and the predetermined temperature relating to the data stored and held in the adjustment-side data storage means 3 (FIG. 2 STEP5).
[0027]
Subsequently, the correction data creating means 6 creates correction data for correcting the data relating to the reference current stored in the EEPROM 24 of the hot air heater x based on the calculation result of the calculating means 5 (FIG. 2 STEP 6). ). The basic concept of creating the correction data will be described with reference to FIG. The adjustment-side data storage means 3 is an ideal fan 22 having no characteristic unevenness. The data relating to the current I-rotational speed R characteristic curve indicated by the dotted line in FIG.(Data related to the reference current according to the ambient temperature T of the fan 22)Is retained. According to this curve, the ambient temperature T is a predetermined temperature T₀The reference current I according to the minimum speed₀₁Is supplied to the fan motor 22b, the rotational speed R of the fan 22 is the minimum rotational speed (1st speed) R.₀₁(See point o in FIG. 3). Also, the ambient temperature T is a predetermined temperature T₀If the temperature is higher by δT than the reference current I₀₁If the fan motor 22b is energized, the rotational speed R of the fan 22 is the minimum rotational speed R.₀₁Is larger by δR '(see point p' in FIG. 3).
[0028]
Here, the rotation speed difference calculated by the calculation means 5 is δR (0 <δR <δR ′), the temperature difference is δT (> 0), that is, the rotation speed R of the fan 22 is the minimum rotation speed R.₀₁Is larger by δR and the ambient temperature T is a predetermined temperature T₀Suppose that the temperature is higher by δT. First, based on the rotational speed difference δR and the δR ′,Stored and held in the adjustment-side data storage means 3IR characteristic curve corresponding to the ambient temperature T indicated by a dotted line in FIG.Data related toIR characteristic curve indicated by a solid lineData related to(See the down arrow a in FIG. 3).ThisBased on the rotational speed difference δR and the corrected RI relationship, the rotational speed R of the fan 22 is the minimum rotational speed R.₀₁The current I to be supplied to the fan motor 22b to be equal to₁It is decreased by (> 0) (see the left downward arrow b in FIG. 3). The correction represented by arrows a and b in FIG. 3 is for eliminating variations in the characteristics of the fans 22.
[0029]
Subsequently, the ambient temperature T is T₀Predetermined temperature T instead of + δT₀Based on the temperature difference δT to appropriately control the rotation speed of the fan 22 when the temperature is isothermal.The corrected data stored and held in the adjustment-side data storage means 3T = T₀IR characteristic curve at + δTData related toT = T₀I-R characteristic curveData related to(See the down arrow c in FIG. 3).ThisBased on the corrected IR characteristic curve, the rotational speed R of the fan 22 is the minimum rotational speed R.₀₁The current I to be supplied to the fan motor 22b so as to agree with δI is δI₂It is increased by (> 0) (see the upward arrow d in FIG. 3). The correction represented by the arrows c and d in FIG. 3 is for eliminating the variation in the ambient temperature of the fan 22 at the time of the correction. According to the knowledge obtained by the inventors of the present application, the correction amount represented by the length of the down arrow c in FIG. 3 is the ambient temperature T and the predetermined temperature T.₀It is optimal that the temperature difference δT is substantially linear.
[0030]
As described above, the ambient temperature T of the fan 22 is the predetermined temperature T.₀Rotation speed R is set to minimum rotation speed R₀₁Therefore, the current I to be supplied to the fan motor 22b is the initial reference current I₀₁Is -δI₁+ ΔI₂Only the corrected value is obtained. According to an algorithm based on such a procedure, the correction data creating means 6 makes this correction amount −δI.₁+ ΔI₂“Correction data” is created (see STEP 6 in FIG. 2).
[0031]
Here, the adjustment-side data communication means 1 communicates the correction data to the data communication means 26 of the hot air heater x (right arrow (4) in FIG. 2), and the data correction means 27 stores and holds it in the EEPROM 24 based on this correction data. Reference current I corresponding to the minimum rotational speed₀₁The data relating to (1) is corrected (FIG. 2 STEP 7).
[0032]
Subsequently, the maximum rotational speed (7-speed) R of the fan 22₀₇The same correction is performed for. Specifically, when the measured time of the timer 2 reaches a second predetermined time longer than the first predetermined time (see STEP 3 in FIG. 2) (YES in STEP 8), request data is transmitted (right arrow in FIG. 2).(2)reference). In response to this, the burner 21 is set to the maximum combustion amount by the combustion amount control means 25a, and the maximum rotational speed (seventh speed) R is applied to the fan motor 22b by the rotational speed control means 25b.₀₇Reference current I corresponding to₀₇Is energized. Then, the correction process is performed according to the rotation speed measurement (STEP 4), the calculation of the rotation speed difference (STEP 5), the generation of correction data (STEP 6), and the data correction (STEP 7). Further, when creating correction data (STEP 6), based on the difference between the first predetermined time and the second predetermined time,Stored and held in the adjustment-side data storage means 3As the IR characteristic curve of the ideal fan 22 indicated by a dotted line in FIG. 3, the rotation speed R is increased by a predetermined value as a whole. Therefore, when correcting the characteristic variation of the fan 22 represented by the arrow a in FIG. 3, the correction amount represented by the length of the arrow a is slightly increased. This is because the number of revolutions of the ideal fan 22 is increased by the above-mentioned predetermined value by the amount that the operating time of the hot air heater x measured by the timer 2 is increased. Therefore, this correction can eliminate variations in the rotational speed of the fan 22 due to differences in the operating time of the hot air heater x.
[0033]
Thus, the reference current I corresponding to the minimum rotation speed (1st speed) and the maximum rotation speed (7th speed) of the fan 22₀₁, I₀₇After the data related to is corrected, the intermediate speed (2nd to 6th speed) R is further increased by the data correction means 27.₀₂~ R₀₆Corresponding to the reference current I stored and held in the EEPROM 24.₀₂~ I₀₆The data relating to is corrected. Specifically, the data related to the reference current corresponding to the intermediate rotational speed is also corrected based on the difference ratio between the intermediate rotational speed and the minimum / maximum rotational speed. For example, the reference rotational speed R corresponding to 1st to 7th speeds₀₁~ R₀₇Are set in order at regular intervals, the reference current I corresponding to the second speed₀₂And the reference current I corresponding to the first speed and the seventh speed₀₁, I₀₇The reference current I corresponding to the second speed so that the ratio of the respective differences to 1 is 5₀₂The data relating to is corrected.
[0034]
According to this adjustment system,Reference current I corresponding to the ambient temperature T of the fan 22 stored in the adjustment side data storage means 3 ₀₁ And I ₀₇ According to the data, the rotation speed R of the fan 22 is the minimum rotation speed R. ₀₁ And maximum rotation speed R ₀₇ (See arrows a and b in FIG. 3). Further, the reference current I corresponding to the ambient temperature T of the fan 22 after the correction is applied. ₀₁ And I ₀₇ On the basis of the data related to ₀ The rotation speed of the fan 22 is the minimum rotation speed R. ₀₁ And maximum rotation speed R ₀₇ To match the reference current I ₀₁ And I ₀₇ (See FIG. 2 STEP6, arrows a and b in FIG. 3). Based on the correction data, the reference current I stored in the EEPROM 24 of the hot air heater x is stored. ₀₁ And I ₀₇ Is corrected (see STEP 7 in FIG. 2).
[0035]
In this way, the data relating to the reference current stored and held in the EEPROM 24 is corrected, whereby the ambient temperature T is changed to the predetermined temperature T. ₀ At the same temperature, minimum rotation speed R ₀₁ And maximum rotation speed R ₀₇ Corresponding to the data stored and held in the EEPROM 24 corresponding to the reference current I ₀₁ And I ₀₇ When the fan 22 is energized, the rotational speed of the fan 22 is the minimum rotational speed R. ₀₁ And maximum rotation speed R ₀₇ Each is controlled accurately. That is, the rotation speed of the fan 22 is reduced to the minimum rotation speed R due to variations in characteristics of the fan 22 and variations in the ambient temperature T of the fan 22. ₀₁ Can be prevented from shifting. Moreover, the combustion air supplied to the burner 21 by the fan 22 is insufficient, and the inconvenience such as the burner 21 causing a combustion failure can be reliably solved.
[0036]
Also, the maximum rotational speed R of the fan 22₀₇about,Data storage means 3Reference current I stored in memory₀₇Data related to hot air heatersxThe rotational speed of the fan 22 that changes according to the operating time of the motor is the maximum rotational speed R₀₇(The increase in the length of the arrow a due to the overall bottom-up of the IR characteristic curve in FIG. 3 is shown. Refer to STEP 5 after STEP 7 in FIG. 2).Then, the correction data related to the reference current is created as described above (see STEP 6 in FIG. 2), and the data related to the reference current stored in the EEPROM 24 is corrected based on this correction data (FIG. 2 STEP 7). ThisThe rotational speed R of the fan 22 is the maximum rotational speed R depending on the operating time of the hot air heater x.₀₇Can be prevented from shifting.
[0037]
Thus, minimum speed (1st speed) R₀₁And maximum speed (7-speed) R₀₇InThe data relating to the reference current stored and held in the EEPROM 24The above correction is made. As a result, the ambient temperature T becomes the predetermined temperature T.₀The reference current I relating to the data stored and held in the EEPROM 24 corresponding to the respective rotational speeds at the same temperature.₀₁, I₀₇When the fan motor 22b is energized, the rotational speed of the fan 22 is set to the minimum rotational speed.R ₀₁ And maximum speedR ₀₇ Can be controlled accurately. Intermediate speed (2nd to 6th) R₀₂~ R₀₆And minimum / maximum speed R₀₁, R₀₇And the reference current I corresponding to the intermediate rotational speed₀₂~ I₀₆The data related to is also corrected. Accordingly, similarly, the rotation speed of the fan 22 is set to the intermediate rotation speed (2nd to 6th speed) R.₀₂~ R₀₆Can be controlled accurately. Accordingly, it is possible to surely eliminate the disadvantage that the combustion air supplied to the burner 21 by the fan 22 is insufficient and the burner 21 causes a combustion failure.
[0038]
Furthermore, the reference current I stored and held in the EEPROM 24 of the hot air heater x by data communication between the adjustment system and the hot air heater x via the adjustment side data communication means 1 and the data communication means 26._0iThe data related to can be easily corrected (see arrows (1) to (4) in FIG. 2). For this reason, compared with the case where a calculation means is provided in each warm air heater x, the structure of the warm air heater x can be simplified and manufacturing cost can be saved.
[0039]
Further, the existing thermistor 29 is used in the hot air heater x as “temperature measuring means” for measuring the ambient temperature of the fan 22, and the existing thermistor 29 is originally used for data communication with the remote controller 28 as data communication means.
