【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、出湯温度と設定温度との偏差量を積分制御手
段を用いて補正する給湯器の制御装置に関する。Description: TECHNICAL FIELD The present invention relates to a water heater controller that corrects a deviation amount between a hot water outlet temperature and a set temperature by using integral control means.
［従来の技術］ 給湯器には、加熱量（燃焼量）を制御装置によって制御
するものがある。制御装置による燃焼量の制御は、水
量、設定温度、入水温度などによって燃焼量を決定する
フィードフォワード制御と、結果から燃焼量を補正する
フィードバック制御とを組み合わせて行うものが考えら
れる。[Prior Art] Some water heaters control a heating amount (combustion amount) by a control device. The control of the combustion amount by the control device may be performed by combining feedforward control that determines the combustion amount based on the water amount, the set temperature, the water inlet temperature, and the like, and feedback control that corrects the combustion amount from the result.
このフィードバック制御には、設定温度と出湯温度との
偏差量を補正する積分制御が考えられる。For this feedback control, integration control for correcting the deviation amount between the set temperature and the hot water temperature can be considered.
［発明が解決しようとする課題］ 一方、給湯器は、燃焼によって得られた熱と水との熱交
換を行う熱交換器を備える。そして、制御装置が、燃焼
量を変化させてから、実際に燃焼量が変化したのを検出
する時間は、熱交換器を流れる水の流速に対応してい
る。つまり、流速の変化に応じて、応答速度が変化す
る。[Problems to be Solved by the Invention] On the other hand, the water heater includes a heat exchanger that exchanges heat between the heat obtained by combustion and water. Then, the time when the control device changes the combustion amount and then detects that the combustion amount actually changes corresponds to the flow velocity of the water flowing through the heat exchanger. That is, the response speed changes according to the change in the flow velocity.
このため、水量を考慮せずに積分制御を行った場合、水
量が増加すると、流速が早くなり、積分補正量が水量に
比較して相対的に少なくなる。逆に水量が減少すると、
流速が遅くなり、積分補正量が水量に比較して相対的に
多くなってしまう。Therefore, when the integral control is performed without considering the water amount, when the water amount increases, the flow velocity becomes faster, and the integral correction amount becomes relatively smaller than the water amount. On the contrary, when the amount of water decreases,
The flow velocity becomes slow, and the integral correction amount becomes relatively large compared to the water amount.
つまり、従来の積分制御は、水量が変化すると、適正な
積分補正量が得られない問題点を備えていた。That is, the conventional integral control has a problem that an appropriate integral correction amount cannot be obtained when the amount of water changes.
本発明は、上記事情に鑑みてなされたもので、その目的

Is provided with a water amount detection sensor 4 for detecting the amount of water, and an integral control means 5 for correcting the deviation amount between the hot water temperature and the set temperature by integral control, and the change amount of the integral correction amount by the integral control means 5 is The technical means is to make the amount of water detected by the water amount detection sensor 4 proportional.
［作用］ 本発明は、積分制御手段による積分補正量の変化量を、
水量に比例させた。これにより、水量が増加すると積分
補正量が増加し、水量が減少すると積分補正量が減少す
る。[Operation] In the present invention, the change amount of the integral correction amount by the integral control means is
It was made proportional to the amount of water. As a result, when the water amount increases, the integral correction amount increases, and when the water amount decreases, the integral correction amount decreases.
この結果、水量の増減によるフィードバックの時間遅れ
を修正し、積分補正量を全水量に亘って均一に評価する
ことができる。As a result, it is possible to correct the time delay of feedback due to the increase / decrease in the amount of water and to evaluate the integral correction amount uniformly over the entire amount of water.
［発明の効果］ 本発明によれば、水量に応じた積分補正量を得ることが

Therefore, even if the amount of water changes, an appropriate amount of integral correction can always be obtained. In other words, the deviation amount between the set temperature and the hot water temperature is corrected without being affected by the water amount, so that the hot water temperature can be set as the set temperature.

When a water flow occurs, the rotating body in the water amount detection sensor 54 rotates and combustion is started. The combustion amount after the start of combustion is the amount of water obtained by various sensors, the incoming water temperature, the hot water temperature that has passed through the heat exchanger 31, and the mixing hot water temperature (outlet temperature) so that the set temperature set by the controller 44 is obtained.

算出される。The feedforward amount FF is the difference between the set temperature Ts set by the controller 44 and the incoming water temperature Ti detected by the incoming water temperature sensor 51, the water amount W detected by the water amount detection sensor 54, and the heat of the heat exchanger 31. It is calculated by the exchange efficiency 1 / eff.
これは、FF＝（Ts−Ti）W/effの式で表される。This is expressed by the formula of FF = (Ts−Ti) W / eff.

とのバイパス比に応じた定数ａとから算出される。The heat exchange capacity correction amount K is the set temperature Ts set by the controller 44 and the hot water temperature To detected by the hot water temperature sensor 53.
Difference (deviation amount), a heat capacity M preset according to the heat exchanger 31 used, the heat exchanger 31 and the bypass channel 32.
It is calculated from a constant a according to the bypass ratio of
これは、Ｋ＝ａ（Ts−To）Ｍの式で表される。This is represented by the equation K = a (Ts-To) M.

Is calculated from the difference (deviation amount), the water amount W detected by the water amount detection sensor 54, and the proportional constant E.
これは、Ｐ＝Ｅ（Ts−To）Ｗの式で表される。なお本実
施例ではＥ＝0.8前後が適正である。This is represented by the equation P = E (Ts-To) W. In the present embodiment, E = about 0.8 is appropriate.

今回の算出する積分補正量で、In-1は前回の算出した積
分補正量を示す。The integral correction amount I is the set temperature set by the controller 44.
The difference (deviation amount) between Ts and the hot water temperature To detected by the hot water temperature sensor 53 is corrected by integral control. The integral constant is b × W so that the amount of change in the integral correction amount I is proportional to the water amount W. And Then, the calculation of the integral correction amount I is expressed by the formula: I n = I n-1 + bW n (Ts-To). Note that I n is the integration correction amount calculated this time, and I n−1 is the integration correction amount calculated last time.
次に、積分補正量Ｉの変化量を水量Ｗに比例させた具体
的な例を示す。Next, a specific example in which the amount of change in the integral correction amount I is made proportional to the water amount W will be shown.

正量Ｉの変化量が多い水量Ｗに応じて増加する。つま
り、水量Ｗの増加に応じて積分補正量Ｉが増加する。When the water amount W is large, the flow velocity of the water flowing through the heat exchanger 31 is high, and the feedback time delay is small. Therefore, when a deviation amount occurs between the set temperature Ts and the hot water outlet temperature To in a state where the water amount W is large, the integral constant is set to b × W, so that the amount of change W of the integral correction amount I is large according to To increase. That is, the integral correction amount I increases as the water amount W increases.
また、水量Ｗが少ない場合は、熱交換器31を流れる水の
流速が遅く、フィードバックの時間遅れが大きい。この

で、積分補正量Ｉの変化量が少ない水量Ｗに応じて減少
する。つまり、水量Ｗの減少に応じて積分補正量Ｉが減
少する。Further, when the water amount W is small, the flow velocity of the water flowing through the heat exchanger 31 is low and the feedback time delay is large. Therefore, when the water volume W is small, the set temperature Ts and the hot water outlet temperature To
When a deviation amount occurs in and, by setting the integration constant to b × W, the amount of change in the integral correction amount I decreases in accordance with the small water amount W. That is, the integral correction amount I decreases as the water amount W decreases.

湯温度Toを設定温度Tsに修正することができる。According to the present embodiment, by setting the integration constant to b × W, the time delay of feedback can be corrected and the integral correction amount I can be evaluated almost uniformly over the total amount of water. Further, by setting the integral correction amount I according to the water amount W, the deviation amount between the set temperature Ts and the hot water temperature To can be corrected regardless of the water amount W, and the hot water temperature To can be corrected to the set temperature Ts.
