ーが無駄になるという欠点があった。To solve this problem, increase the amount of water to the maximum before heating, and after a certain period of heating, if the input to the heater is at the maximum and the hot water temperature drops relative to the set temperature, it is already possible to reduce the amount of water. Although this is known, the above method has the drawback that the appropriate temperature cannot be obtained until a certain period of time has passed after heating, which is not only inconvenient for the user, but also that the heating energy during that time is wasted.

以下その実施例を添付図面によって説明する。In order to achieve this object, the present invention detects the inlet water temperature and outlet temperature of a heat exchanger heated by a heating device using temperature detectors, and calculates a signal from a hot water outlet temperature setting section and a hot water outlet temperature signal.

直ちに出湯温度が設定温度と等しく制御される。The curve has a characteristic that matches a capacity curve determined by the heating device 26, which will be described later. Figure 3 shows the change in the water volume setting with respect to the temperature difference between the hot water outlet temperature and the inlet water temperature (hot water temperature rise value), and the curve E shows the change in the water volume setting with respect to the temperature difference between the hot water temperature setting and the water inlet temperature (hot water temperature rise value).
The characteristics of the water flow controller 1 correspond to the curve DK71 in FIG. 3a. Curve F shows the relationship between the temperature difference between the outlet hot water setting temperature and the inlet water temperature (hot water temperature increase value) and the water amount in the case of the present invention, and the curve G and curve H indicate the relationship between the water inlet temperature detector in addition to the water flow controller 1. The curve F9 curve G9 curve H corresponds to the curve M9 curve B1 curve C of FIG. 3 &, respectively. For example, if the hot water temperature rise value is relatively lower than the set hot water outlet temperature and the inlet water temperature and is at T1 in FIG. 3, the water amount is normally set to Ql. After that, when water flow is started by the user, the amount of water Q111 flows, the heating device 26 starts combustion, and the hot water temperature rise value becomes T1, which matches the setting and also matches the capacity curve y. Therefore, hot water is supplied at full capacity. When the water amount is set to Q2 due to variations, the hot water temperature increase value becomes T2. In this case, the deviation of the hot water outlet temperature with respect to the hot water outlet temperature setting is calculated by the water amount resetting control unit 32 using the respective signals of the hot water outlet temperature setting unit 28 and the outlet hot water temperature detector 22 shown in FIG. 2 via the timer 31. The timing device 31 connects the heating device 26 to the heat exchanger 1.
4. Set the length of the heating time delay. The water amount resetting control unit 32 drives the drive device 21 if the temperature difference between the set hot water tap temperature and the actual hot water tap temperature is greater than or equal to a certain set range. Therefore, since the actual hot water temperature rise value is T2 with respect to the set hot water temperature rise value T1, the drive device 21 is driven for a certain period of time or according to the temperature deviation by the signal from the water amount resetting control section 32, and the water amount is reduced to a small amount. is corrected and reset to Ql, and as a result, the hot water temperature increase value matches T1. In this case, the change in water amount is small, so the response is quick in terms of time. Furthermore, if the water flow rate is set to Q3 due to variations even though the hot water outlet temperature is set to T1, the hot water temperature increase value becomes T3. In this case, the hot water temperature setting section 28
The deviation from the signal from the hot water temperature detector 23 is determined by the heating control unit 2.
9, the heating amount is adjusted by the heating controller 26,
The hot water temperature is immediately controlled to be equal to the set temperature.

・Q6はいずれも能力曲線Fよりも水量が大きい。この
ため必要以上に水量が制限されて加熱装置26の加熱量
が制限されるということがなく、能力全開で給湯する。In this way, when the hot water temperature rise value is low, if the standard value of the water flow rate setting is on the capacity curve F, even if there is variation, the time until the hot water temperature reaches the set temperature is short. Next, if the hot water temperature rise value is set to a relatively high temperature and is at T4 in Figure 3, the water volume is set to Q4, Q6, and Q6, respectively, depending on the standard value or variation, and the hot water temperature rise value is T4.
It becomes 5, T6, T7. In this case, as described above, the deviation of the hot water outlet temperature with respect to the hot water outlet temperature setting is calculated by the water amount resetting control section 32 via the timer 31, and the one drive device 21 is driven to reset the water amount to Q7, thereby increasing the hot water temperature. value T4
match. Water volume setting values Q4 and Q6 including variations
・Q6 has a larger water volume than capacity curve F in all cases. Therefore, the amount of water heated by the heating device 26 is not restricted more than necessary, and hot water is supplied at full capacity.

る。In order to limit the amount of water by the user, it is necessary to adjust the capacity of the heating device 26 in order to control the temperature of the hot water. In this case, the heating controller 29 calculates the deviation between the signals of the hot water outlet temperature setting unit 28 and the hot water outlet temperature detector 23, and the heating amount is adjusted by the heating controller 26, so that the hot water outlet temperature is controlled to be equal to the set temperature.

When the hot water outlet temperature setting is relatively low, the water amount is set near the theoretical water amount, and when the hot water outlet temperature setting is relatively high, the water amount is set above the theoretical water amount, so the water amount can be adjusted in advance without waiting for the hot water temperature to rise by the heating device. The time required for stabilizing the amount of water, that is, stabilizing the temperature of the water, is short. The response time is particularly short when accurate temperature control is required, such as at low temperature settings, such as in the shower. Furthermore, in high-temperature settings such as when reheating a bath, which requires hot water to be supplied at full capacity, hot water can be supplied at full capacity even if there are variations in the amount of water.
また水量初期設定後に出湯温度と設定温度とを演算し、

ある。In addition, after the initial setting of the water amount, the hot water temperature and the set temperature are calculated,
Since the water amount is finely adjusted by the water amount resetting control section via the timer, highly accurate hot water temperature control is possible.

A heating controller of the heating device, an inlet water temperature detector and an outlet temperature detector provided at the inlet and outlet of the heat exchanger, an outlet temperature setting section, a heating control section of the heating controller, and a water amount initial setting. a hot water supply controller consisting of a control section, and the water amount initial setting section calculates the theoretical water amount - (heating capacity of the heating device)/(temperature difference between the set temperature and the incoming water temperature) and controls the drive device. The hot water heating control device sets the amount of water to be approximately equal to the theoretical water amount when the hot water tap temperature is low and is larger than the theoretical water amount when the hot water tap temperature is high.
求の範囲第1項記載の給湯加熱制御装置。(2) The hot water heating control device according to claim 1, wherein the drive device is activated before the heating device is activated.
信号を時限装置を介して演算する水量再設定制御部を有
し、前記水量再設定制御部によって駆動装置を制御する
特許請求の範囲第1項記載の給湯加熱制御装置。(3) The hot water supply controller has a hot water supply temperature setting section and a water volume resetting control section that calculates the signal of the hot water temperature detector via a timer, and the water flow rate resetting control section controls the drive device. The hot water heating control device according to scope 1.
