本発明は、バーナへ燃焼用空気を供給するなめに送風機
を備えた燃焼制御装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a combustion control device equipped with a blower for supplying combustion air to a burner.
［従来の技術］
送風機を備えた燃焼制御装置では、送風機の作動を確認

の回転数を検出し、回転軸の回転数が所定回転数以上に
なったときに、送風機は正常に作動したものとしてバー
ナへの燃料供給を開始するとともに、点火装置を作動し
て点火を行っている。[Conventional technology] In order to confirm the operation of the blower, a combustion control device equipped with a blower detects the rotation speed of an electric motor with blower blades fixed to the rotating shaft, and detects when the rotation speed of the rotating shaft reaches a predetermined rotation speed. When the number exceeds the number, the blower assumes that it is operating normally and starts supplying fuel to the burner, and also operates the ignition device to ignite the burner.
［発明が解決しようとする課題］

うため、大変危険な場合がある。[Problem to be solved by the invention] However, in the past, the operation of the blower was confirmed simply by checking whether the rotation speed of the rotating shaft of the electric motor was equal to or higher than a predetermined rotation speed. This is because it is determined that the fan is operating properly even when the rotation speed greatly exceeds the specified number, such as when the load on the blower is reduced due to blockage, or when the blade is loosely fixed to the rotating shaft. , can be very dangerous.
本発明は、送風機の回転数が異常に多くなるような場合
には、危険防止のために点火を行わない安全な燃焼制御
装置を提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a safe combustion control device that does not ignite in order to prevent danger when the number of revolutions of a blower becomes abnormally high.
［課題を解決するための手段］
本発明は、バーナへ燃焼用空気を供給する送風機を備え

記点火作動を開始することを技術的手段とする。[Means for Solving the Problems] The present invention includes a blower that supplies combustion air to a burner, and an ignition control means that operates an ignition device and starts supplying fuel to the burner to automatically operate the ignition. In the combustion control device, the ignition control means includes a rotation speed detection means for detecting the rotation speed of the blower, and starts the ignition operation when the rotation speed of the blower is detected within a predetermined rotation speed range. technical means to do so.
［作用および発明の効果］
本発明では、回転数検出手段によって検出される送風機
の回転数が、所定の回転数幅内のときにのみ、点火制御
手段による点火作動が開始される。[Operation and Effects of the Invention] In the present invention, the ignition control means starts the ignition operation only when the rotation speed of the blower detected by the rotation speed detection means is within a predetermined rotation speed range.
従って、送風機の回転数が所定の回転数に満たない場合
には、バーナへ燃料が供給されないため、燃料がバーナ
に供給されてバーナ付近に充満することがない、また、
給気口や排気口が塞がれたり、あるいは羽根が回転軸に
緩く止められたために回転軸が空回りして、所定の回転
数以上になった場合にも、燃料供給が行われないため、
燃料ガスが燃焼機器に充満したり、燃焼用空気が不足し
たまま燃焼が開始されることがないため安全である。Therefore, when the rotational speed of the blower is less than a predetermined rotational speed, fuel is not supplied to the burner, so fuel is not supplied to the burner and fills the vicinity of the burner.
Even if the rotating shaft idles due to the air intake or exhaust port being blocked, or the blades are loosely attached to the rotating shaft, and the rotation speed exceeds the specified speed, fuel will not be supplied.
It is safe because the combustion equipment will not be filled with fuel gas or combustion will not start with insufficient combustion air.

にしている。The control device 30 starts combustion in a predetermined sequence and controls the blower 17 and the proportional valve 22 to control the amount of combustion. In the combustion amount control, the required combustion amount is determined based on the outlet hot water temperature set by the controller 31 and detection signals from a water flow sensor (not shown), an inlet water temperature thermistor, and an outlet hot water temperature thermistor, and the blower 17 is controlled according to the amount of combustion.
In order to drive the blower 17 and supply fuel according to the operating state of the blower 17, the Hall element 17a drives the blower 17.
The rotational speed of the rotating shaft is detected, and the proportional valve 22 is energized according to the detected rotational speed, so that combustion is performed at an appropriate air-fuel ratio.

に点火をしないようにするためである。In this control, ignition is performed only when the rotation speed of the blower 17 is within a certain range with respect to a predetermined rotation speed determined for slow ignition, and ignition is not performed otherwise. This is because in the gas water heater 10, the blower 17 does not rotate, or even if it rotates, the air supply port that takes in combustion air or the exhaust port that discharges combustion gas may be blocked for some reason. This is to prevent ignition in such cases, since proper air will not be supplied and combustion will not occur properly, which could be dangerous.

The rotation speed N changes accordingly. In addition, since there are some differences in the rotation speed due to variations in the gas water heater 10, the rotation speed for slow ignition is 1000 [r, p, m, upper and lower 100 [r, I], respectively. 9 within m,]

要燃焼量に応じて変更されるため、点火時の回転数を特
定できない。In the above, an embodiment in which slow ignition is performed has been described, but a combustor may also be used in which ignition is performed at the required combustion amount calculated based on hot water temperature setting means, etc., without particularly performing slow ignition control at the time of ignition. In this case, the rotation speed of the blower is changed at the time of ignition depending on the required combustion amount, so the rotation speed at the time of ignition cannot be determined.
従って、必要燃焼量に基づいて決定される回転数を基準
回転数とし、検出される回転数が基準回転数に対してそ
の上下の一定幅内にあるときを許容回転数として、この
ときに点火を行うようにすればよい。Therefore, the rotation speed determined based on the required combustion amount is the reference rotation speed, and when the detected rotation speed is within a certain range above and below the reference rotation speed, the allowable rotation speed is set. All you have to do is do this.
また、緩点火を行わない燃焼器の場合には、必要燃焼量
に応じて基準回転数を変更しないで、許容回転数をあら
かじめ広い幅で固定して設定してもよい。Furthermore, in the case of a combustor that does not perform slow ignition, the allowable rotation speed may be fixed and set in advance within a wide range without changing the reference rotation speed according to the required combustion amount.
以上のとおり、本発明によれば、送風機の回転数が所定
の回転数幅内にない時には、点火されないため、安全を
確保することができる。As described above, according to the present invention, when the rotation speed of the blower is not within a predetermined rotation speed range, the ignition is not performed, so safety can be ensured.
また、送風のための羽根が回転軸に正しく固定されてい
なくて緩んでしまった場合などにも、所定回転数以上に
なった回転数が検出されるため、点火を停止することが
できる。したがって、送風機の組み付けの経時変化に対
する安全確保にも有効である。Furthermore, even if the blade for blowing air is not properly fixed to the rotating shaft and becomes loose, the ignition can be stopped because the rotation speed is detected to be equal to or higher than the predetermined rotation speed. Therefore, it is also effective in ensuring safety against changes in the assembly of the blower over time.
