【０００３】 給湯熱交換器５の入側には給水管14が接続され、この給水管14には給水温度セ ンサ15と給水電磁弁16が設けられている。給湯熱交換器５の出側には給湯管17が 接続され、その先端側は台所等の所望の場所に導かれている。給湯管17には給湯 温度を検出する給湯温度センサ18と給湯量を検出する水量センサ20とが設けられ ている。A water supply pipe 14 is connected to the inlet side of the hot water supply heat exchanger 5, and the water supply pipe 14 is provided with a water supply temperature sensor 15 and a water supply solenoid valve 16.

The hot water supply pipe 17 is provided with a hot water supply temperature sensor 18 for detecting the hot water supply temperature and a water amount sensor 20 for detecting the hot water supply amount.
【０００４】 風呂熱交換器７には往管23と戻り管24とからなる追い焚き循環管路22が接続さ れており、この追い焚き循環管路22には循環ポンプ25と循環湯水の温度を検出す る風呂湯温検出センサ26と浴槽21の水位を検出する圧力センサ27が設けられてい る。そして、追い焚き循環管路22と給湯管17は連通管19を介して接続されており 、この連通管19には注湯切替弁29が設けられている。The bath heat exchanger 7 is connected to a reheating circulation line 22 composed of a forward pipe 23 and a return pipe 24.

【０００５】 前記各センサ15，18，20，26，27の検出信号は制御装置28に加えられており、 この制御装置28はリモコン30で設定される給湯温度と風呂温度との設定情報を受 けて、ファン８の回転制御と比例弁12，13の開弁量制御と、循環ポンプ25の動作 制御を行い給湯運転と追い焚き運転を行う。なお、図中９はガス遮断を行う電磁 弁である。Detection signals of the sensors 15, 18, 20, 26, 27 are applied to a control device 28, which receives setting information of hot water supply temperature and bath temperature set by a remote controller 30.

【０００６】[0006]
この種の給湯付風呂釜では、給湯側から広い温度範囲の湯が出せるように、最 大燃焼能力と最小燃焼能力間の範囲を広く設定している関係上、給湯側の燃焼能 力に合わせてファン８の回転制御が行われている。 In this type of bath kettle with hot water supply, the range between the maximum combustion capacity and the minimum combustion capacity is set wide so that hot water in a wide temperature range can be discharged from the hot water supply side. Rotation control of the fan 8 is performed.
【０００７】 このため、給湯側から温度の低い湯を出すときには給湯比例弁12の開度が絞ら れる結果、これに合わせてファン８の回転数が低下する方向に制御されるので、 図４の特性図から明らかなように、ファン８から給湯バーナ４に供給される空気 量は小さくなり、同時に風呂バーナ６に供給される空気量も小さくなる。このと き、風呂バーナ６を良好な燃焼状態を保つためには風呂比例弁13の開弁量を絞ら なければならず、そうすると、必然的に風呂バーナ６の燃焼熱量が小さくなり、 風呂の追い焚き時間が長く掛かってしまうという問題が生じる。Therefore, when hot water having a low temperature is discharged from the hot water supply side, the opening degree of the hot water supply proportional valve 12 is narrowed, and as a result, the rotational speed of the fan 8 is controlled in a direction in which it decreases. As is clear from the characteristic diagram, the amount of air supplied from the fan 8 to the hot water supply burner 4 becomes small, and at the same time, the amount of air supplied to the bath burner 6 also becomes small. In this case, in order to keep the bath burner 6 in a good combustion state, the opening amount of the bath proportional valve 13 must be reduced, which inevitably reduces the combustion heat amount of the bath burner 6 and causes the bath to burn. There is a problem that the burning time is long.
【０００８】 このような問題を解消するためには、給湯比例弁の開弁量が絞られた場合にお いても風呂バーナ６には十分な空気量を供給し、最大能力でもって燃焼できるこ とが望ましい。そうすれば、風呂比例弁13は常に全開状態でよく、開弁量を絞る 必要もなくなるので、風呂比例弁13は不用となり、省略できることになる。In order to solve such a problem, it is necessary to supply a sufficient amount of air to the bath burner 6 even if the opening amount of the hot water supply proportional valve is throttled so that combustion can be performed with the maximum capacity. And is desirable. In that case, the bath proportional valve 13 may be in a fully open state at all times, and it is not necessary to reduce the opening amount, so that the bath proportional valve 13 is unnecessary and can be omitted.
【０００９】 本考案は上記事情に基づいてなされたものであり、その目的は、給湯器側の燃 焼能力を低くした場合においても風呂側は最大能力で燃焼することができ、しか も、従来の風呂比例弁を省略して装置構成の簡易化を図ることができる給湯付風 呂釜の燃焼制御装置を提供することにある。The present invention has been made based on the above circumstances, and an object thereof is to allow the bath side to burn at the maximum capacity even when the burning capacity of the water heater side is lowered, but only in the conventional case. Another object of the present invention is to provide a combustion control device for a stove with a hot water supply, which can simplify the device configuration by omitting the bath proportional valve.
【００１０】[0010]
本考案は上記目的を達成するために、次のように構成されている。すなわち、 本考案は、共有の一個のファンから取り込まれる空気が分岐通路を介して給湯バ ーナと風呂バーナとに供給される給湯付風呂釜であって、給湯バーナの燃焼に必 要な空気量と風呂バーナの燃焼に必要な空気量との総空気量を取り込むようにフ ァンの回転制御を行うファン回転制御部と、前記分岐通路の分岐部から給湯バー ナに至る通路間に設けられ給湯バーナの燃焼量に応じて給湯バーナへ導かれる空 気量を調整する空気流量分配調整手段とを備えたことを特徴として構成されてい る。 The present invention is configured as follows to achieve the above object. That is, the present invention is a bath kettle with hot water supplied to a hot water supply burner and a bath burner through a branch passage, and the air taken in from one shared fan is the air required for combustion of the hot water supply burner. Installed between the fan rotation control unit that controls the rotation of the fan so as to take in the total amount of air required for combustion of the bath burner and the passage from the branch portion of the branch passage to the hot water supply burner. The air flow distribution adjusting means for adjusting the amount of air introduced into the hot water supply burner according to the combustion amount of the hot water supply burner is provided.
【００１１】[0011]
上記構成の本考案において、給湯側と風呂側とが同時に運転されているときに は、ファンから給湯バーナと風呂バーナに必要な空気を取り込むようにファンの 回転制御が行われる。この状態で、給湯側の燃焼能力を小さくする方向に変更す ると、給湯側の能力が小さくなる分だけファンの回転が低下する方向に制御され るので、ファンから供給される空気量は減少する。このとき、空気流量分配調整 手段は給湯バーナ側に供給される空気量を給湯側の能力に合わせて小さくする方 向に絞る結果、ファンの空気取り込み量が小さくなるにも拘わらず、風呂バーナ 側には空気量が変化なく分配供給されることとなり、風呂側の能力を落とすこと なく風呂バーナの燃焼運転が行われる。 In the present invention having the above configuration, when the hot water supply side and the bath side are operated at the same time, the rotation control of the fan is performed so as to take in the necessary air from the fan to the hot water supply burner and the bath burner. If the combustion capacity of the hot water supply side is changed in this state, the rotation of the fan will be controlled to decrease as the capacity of the hot water supply side becomes smaller, and the amount of air supplied from the fan will decrease. To do. At this time, the air flow distribution adjusting means narrows the amount of air supplied to the hot water supply burner side in accordance with the capacity of the hot water supply side, and as a result, the air intake amount of the fan becomes small, but the bath burner side becomes smaller. The air quantity is distributed and supplied to the bath burner, and the combustion operation of the bath burner is performed without deteriorating the capacity of the bath side.

以下、本考案の実施例を図面に基づいて説明する。なお、本実施例の説明にお いて、従来例と同一の部分には同一符号を付し、その詳細な重複説明は省略する 。図１には本考案の燃焼制御装置を装備した給湯付風呂釜のシステムが示され、 また、図２には本考案に係る燃焼制御装置の一実施例を示すブロック構成が示さ れている。本実施例において特徴的なことは、従来例の風呂比例弁13を省略する とともに、給湯側の燃焼能力と風呂側の燃焼能力とに必要な総空気量を取り込む ようにファンの回転を制御するファン回転制御部と、ファン８から供給される空 気量を給湯側の能力と風呂側の能力に応じて分配供給する空気流量分配調整手段 を設けたことであり、それ以外の構成は従来例と同様である。前記空気流量分配 調整手段は分岐通路10の分岐部に設けられた空気分配機構部31を有している。こ の空気分配機構部31はダンパモータ32と、このダンパモータ32の回転出力軸に連 動して、給湯バーナ４側に通じる通路の通路面積を可変調整するダンパ33とによ って構成されている。 Embodiments of the present invention will be described below with reference to the drawings. In the description of the present embodiment, the same parts as those in the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 1 shows a system of a bathtub with hot water supply equipped with the combustion control device of the present invention, and FIG. 2 shows a block configuration showing an embodiment of the combustion control device according to the present invention. The characteristic of this embodiment is that the bath proportional valve 13 of the conventional example is omitted, and the rotation of the fan is controlled so as to take in the total amount of air required for the combustion capacity on the hot water supply side and the combustion capacity on the bath side. The fan rotation control section and the air flow rate distribution adjusting means for distributing and supplying the amount of air supplied from the fan 8 according to the capacity of the hot water supply side and the capacity of the bath side are provided. Is the same as. The air flow rate distribution adjusting means has an air distribution mechanism section 31 provided at a branch portion of the branch passage 10. The air distribution mechanism section 31 is composed of a damper motor 32 and a damper 33 that is operatively connected to a rotation output shaft of the damper motor 32 and variably adjusts a passage area of a passage leading to the hot water supply burner 4 side. ..
【００１３】 この実施例の燃焼制御装置は、図２に示す如く、信号入力部34と、燃焼量制御 部35と、ファン回転制御部36と、空気量演算部38と、空気分配量制御部37とを有 して構成されており、この空気分配量制御部37と、前記空気分配機構部31は空気 流量分配調整手段を構成している。As shown in FIG. 2, the combustion control device of this embodiment includes a signal input unit 34, a combustion amount control unit 35, a fan rotation control unit 36, an air amount calculation unit 38, and an air distribution amount control unit. 37, and the air distribution amount control section 37 and the air distribution mechanism section 31 constitute an air flow rate distribution adjusting means.
【００１４】 前記信号入力部34は、水量センサ20と、給湯温度センサ18と、給水温度センサ 15との各検出信号を取り込むとともにリモコン30からの信号を取り込み、これら の各信号を燃焼量制御部35に加える。燃焼量制御部35は風呂燃焼量制御部35ａと 給湯燃焼量制御部35ｂとを有しており、風呂燃焼量制御部35ａはリモコン30から 加えられる追い焚き設定温度と風呂湯温検出センサ26の浴槽湯水の検出湯温とを 比較し、検出湯温が追い焚き設定温度に至るまで風呂バーナ６を最大燃焼能力で 燃焼制御する。給湯燃焼量制御部35ｂは給湯温度センサ18から加えられる給湯温 度と、給水温度センサ15から加えられる給水温度と、水量センサ20から加えられ る給湯量とに基づき、給湯温度がリモコン30で設定された給湯設定温度になるよ うに給湯比例弁12の開弁量を制御して給湯バーナ４の燃焼運転を行う。The signal input unit 34 takes in each detection signal of the water amount sensor 20, the hot water supply temperature sensor 18, and the water supply temperature sensor 15, and also takes in a signal from the remote controller 30, and outputs each of these signals to the combustion amount control unit. Add to 35. The combustion amount control unit 35 has a bath combustion amount control unit 35a and a hot water supply combustion amount control unit 35b. The bath combustion amount control unit 35a includes a reheating setting temperature and a bath water temperature detection sensor 26 added from the remote controller 30. Combustion control of the bath burner 6 is performed with the maximum combustion capacity by comparing with the detected hot water temperature of the bath water. The hot water supply combustion amount control unit 35b sets the hot water supply temperature with the remote controller 30 based on the hot water supply temperature added from the hot water supply temperature sensor 18, the water supply temperature added from the water supply temperature sensor 15, and the hot water supply amount added from the water amount sensor 20. The opening amount of the hot water supply proportional valve 12 is controlled so that the set hot water temperature is reached, and the hot water supply burner 4 is burned.
【００１５】 空気量演算部38は、風呂燃焼量制御部35ａによって制御される燃焼量に必要な 空気量Ｑ1 と、給湯燃焼量制御部35ｂによって制御される燃焼量に必要な空気量 Ｑ2 と、風呂側と給湯側の燃焼に必要な総空気量Ｑ1 ＋Ｑ2 を算出する。ファン 回転制御部36は前記空気量演算部38によって算出された総量の空気量を取り込む ようにファン８の回転制御を行う。空気分配量制御部37は前記空気量演算部38に よって算出された給湯燃焼に必要な空気量Ｑ2 がファン８から分岐通路を経て給 湯バーナ４に供給されるようにダンパモータ32の回転角を制御する。この回転角 の制御に際しては、予め内蔵するメモリにダンパ33の回転角と空気量との関係を 示すグラフデータを与えておき、前記空気量演算部38により給湯バーナ４側への 空気量Ｑ2 が算出されたときに、この算出値に対応するダンパ33の回転角をグラ フデータから読み取り、この回転角となるようにダンパモータ32を回転制御する ことにより給湯バーナ４に必要量の空気が供給されることになり、このとき、風 呂バーナ６側にも必要量の空気量Ｑ1 が供給されることになる。The air amount calculation unit 38 has an air amount Q 1 required for the combustion amount controlled by the bath combustion amount control unit 35 a and an air amount Q 2 required for the combustion amount controlled by the hot water supply combustion amount control unit 35 b. Then, the total air amount Q 1 + Q 2 required for combustion on the bath side and the hot water supply side is calculated. The fan rotation control unit 36 controls the rotation of the fan 8 so as to take in the total amount of air calculated by the air amount calculation unit 38. The air distribution amount control unit 37 controls the rotation angle of the damper motor 32 so that the air amount Q 2 calculated by the air amount calculation unit 38 necessary for hot water supply combustion is supplied from the fan 8 to the hot water supply burner 4 through the branch passage. To control. In controlling the rotation angle, graph data showing the relationship between the rotation angle of the damper 33 and the air amount is given to a built-in memory in advance, and the air amount calculation unit 38 supplies the air amount Q 2 to the hot water supply burner 4 side. Is calculated, the rotation angle of the damper 33 corresponding to this calculated value is read from the graph data, and the damper motor 32 is rotationally controlled so that this rotation angle is obtained, so that the required amount of air is supplied to the hot water supply burner 4. Therefore, at this time, the required amount of air Q 1 is also supplied to the wind burner 6 side.
【００１６】 このように、この実施例では、空気量演算部38により給湯バーナ４と風呂バー ナ６に必要な空気の総量が演算され、この総量の空気を取り入れるようにファン ８の回転が制御されるから、リモコン30で給湯の設定温度が変更された場合でも 、その変更後に給湯バーナ４と風呂バーナ６の両方に必要な空気量が演算されて 取り込まれることとなり、しかも、この給湯設定温度の変更により給湯バーナ４ に供給される空気量が変更されても風呂バーナ６に供給される空気量は影響を受 けない。したがって、たとえ、給湯設定温度が低い温度に変更され、給湯比例弁 12の開弁量が絞られて給湯バーナ４に供給されるガス量が減少し、これに応じて 給湯バーナ４に供給される空気量が減少する方向に制御されても、図３に示すよ うに、風呂バーナ６は最大燃焼能力でもって良好に燃焼運転されるので、浴槽21 の湯水を最大燃焼能力で追い焚きすることができ、給湯器側に影響を受けずに風 呂の追い焚きを短時間のうちに終了させることができる。As described above, in this embodiment, the total amount of air required for the hot water supply burner 4 and the bath burner 6 is calculated by the air amount calculation unit 38, and the rotation of the fan 8 is controlled so as to take in this total amount of air. Therefore, even if the set temperature of hot water supply is changed by the remote control 30, the required air amount for both hot water supply burner 4 and bath burner 6 will be calculated and taken in after the change. Even if the amount of air supplied to the hot water supply burner 4 is changed by changing the above, the amount of air supplied to the bath burner 6 is not affected. Therefore, even if the hot water supply set temperature is changed to a low temperature, the opening amount of the hot water supply proportional valve 12 is throttled, the amount of gas supplied to the hot water supply burner 4 is reduced, and the hot water supply burner 4 is supplied accordingly. Even if the amount of air is controlled to decrease, as shown in FIG. 3, the bath burner 6 is satisfactorily burned with the maximum combustion capacity, so that the hot and cold water in the bathtub 21 can be reheated with the maximum combustion capacity. As a result, the reheating of the wind can be completed in a short time without being affected by the water heater side.
【００１７】 また、従来の風呂比例弁13を省略できるので、装置構成の簡易化を達成するこ とができる。Moreover, since the conventional bath proportional valve 13 can be omitted, the simplification of the device configuration can be achieved.
【００１８】 なお、本考案は上記実施例に限定されることはなく、様々な実施の態様を採り 得る。例えば、上記実施例では、空気分配機構部31を分岐通路10の分岐部に設け たが、この空気分配機構部31は分岐通路10の分岐部から給湯バーナ４に至る任意 の通路位置に設けることができるものである。The present invention is not limited to the above-mentioned embodiment, and various embodiments can be adopted. For example, in the above embodiment, the air distribution mechanism portion 31 is provided at the branch portion of the branch passage 10. However, the air distribution mechanism portion 31 is provided at an arbitrary passage position from the branch portion of the branch passage 10 to the hot water supply burner 4. Can be done.
【００１９】 また、上記実施例ではファン８から給湯バーナ４と風呂バーナ６に供給する空 気量をダンパ33を用いて分配したが、この空気量の分配は給湯側の燃焼能力に合 わせて給湯バーナ４側に供給される空気量を通路面積を可変して制御できるもの であればよく、ダンパ33以外の様々な機構を用いて構成することができるもので ある。Further, in the above embodiment, the air amount supplied from the fan 8 to the hot water supply burner 4 and the bath burner 6 was distributed using the damper 33. However, the distribution of this air amount is made to match the combustion capacity of the hot water supply side. It is sufficient that the amount of air supplied to the hot water supply burner 4 side can be controlled by varying the passage area, and various mechanisms other than the damper 33 can be used.
【００２０】[0020]
本考案は、給湯バーナの燃焼と風呂バーナの燃焼とに必要な空気の総量を取り 込むようにファンの回転制御を行い、空気流量分配調整手段により、給湯バーナ 側に供給される空気量を給湯バーナの燃焼に必要な空気量となるように調整する ように構成したものであるから、必然的に、風呂バーナに供給される空気量も風 呂バーナの燃焼に必要な空気量となる。したがって、給湯側の給湯比例弁の開弁 量が絞られてファンの回転数が減少する方向に制御されても、風呂バーナ側はこ れに影響を受けずに必要量の空気を取り込んで最大能力で燃焼運転することがで きるので、給湯側の運転に影響を受けずに最大燃焼能力でもって追い焚き運転を 行うことができ、給湯運転の如何に拘わらず浴槽湯水を短時間のうちに沸き上げ ることが可能となる。 The present invention controls the rotation of the fan so that the total amount of air required for the combustion of the hot water supply burner and the combustion of the bath burner is taken in, and the amount of air supplied to the hot water supply burner side is supplied by the air flow distribution adjustment means. Since the air burner is configured to be adjusted to the air amount required for combustion, the amount of air supplied to the bath burner is necessarily the air amount required for combustion of the air burner. Therefore, even if the opening amount of the hot water supply proportional valve on the hot water supply side is throttled to control the fan speed to decrease, the bath burner side takes in the required amount of air without being affected by this. Since it is possible to perform combustion operation with the capacity, it is possible to perform the reheating operation with the maximum combustion capacity without being affected by the operation on the hot water supply side. It is possible to boil.
【００２１】 また、従来の風呂比例弁が省略できるので、その分、装置構成の簡易化と装置 コストの低減化を図ることができる。Moreover, since the conventional bath proportional valve can be omitted, the device configuration can be simplified and the device cost can be reduced accordingly.
