The purpose is to provide a new control device that can control the temperature of hot water.
ガス湯沸器を例にあげて説明を行う。This will be explained using a gas water heater as an example.

器３としてはＰｉＤ制御器等がよく用いられる。FIG. 1 is a block diagram of a conventional gas water heater, in which combustion heat in a burner 1 and water are exchanged in a heat exchanger 2 to provide hot water. A signal TWO from the hot water temperature detector 4 and a signal TWR from the temperature setting device 6 are input to the temperature controller 3.
A predetermined combustion amount is determined from the difference between and TWRO, and a control signal is output to the supply heat amount controller 6 to control the outlet hot water temperature. Here, as the outlet hot water temperature detector 4, for example, a thermistor is often used, and as the temperature controller 3, a PiD controller or the like is often used.

。FIG. 2 is a diagram showing the relationship between the hot water output amount W of the gas water heater and the temperature rise ΔT. The solid line represents the characteristics at the maximum combustion amount. In other words, if the maximum combustion amount Qq ma, the temperature rise ΔT, and the flow rate W are the combustion efficiency η, η・Q = W・ΔT , , , , ,
(1) qma! So, . Therefore, there is no temperature rise ΔT greater than that indicated by the solid line. For example, when the maximum combustion amount is Qgma, if the hot water output is Wl, the temperature rise ΔT will be ΔT1 as shown in the figure. The temperature controller 3 described above operates effectively when the temperature rise is ΔT - ΔT1 and the hot water output amount W is less than W1. If W > Wl, control becomes impossible and the hot water temperature TWO cannot reach the set temperature TWR.
このように最大燃焼量Ｑ によって出湯温ｍａｘ

If the amount of heat supplied to the water heater is at the maximum even after a certain period of time has passed after the start of use, and the temperature deviation TER remains, the predetermined time expressed by the following formula (3) % formula % (3) with respect to the above TER outputs a control signal to the supply water amount control device 9 to reduce the supply water amount. The relationship expressed by equation (3) is shown in FIG. 4, where the horizontal axis is the temperature deviation TER and the vertical axis is the predetermined time t.

Ｒ＝Ｏの湯温が得られる。In this method, by measuring the temperature deviation TER,
The predetermined time for outputting the control signal is determined by a simple calculation as shown in equation (3), and the deviation TE is determined by the water flow control effect.

手も向上する。Furthermore, if the set temperature is changed during use or the flow rate at a certain load F fluctuates, the predetermined time for outputting the control signal is determined based on the value of the deviation TER in the steady state after the transient period according to equation (3). , the amount of water is controlled by a water supply amount control device. Through this operation, hot water at the set temperature is always obtained, and when the set temperature is lowered during use, the water supply amount control device is initialized.
The amount of water supplied that is limited by the hot water supply port can be reduced, and the usability is improved.
ところで前述した、「使用開始後ある時間」と「過渡時

来る。As described above, according to the water heater control device of the present invention, the amount of hot water W is always limited to a range where the hot water temperature can be controlled.
You can get the excellent effect of getting hot water at the desired temperature. Further, from the temperature deviation TER in the steady state, the predetermined time can be very easily determined in accordance with the relationship of the above-mentioned equation (3), and it can also be limited to the maximum position where the hot water temperature can be controlled.
