Abstract

PURPOSE:To prevent deterioration of characteristics of hot-water delivery by a method wherein a water amount correcting unit, correcting a control water amount so as to have a given water amount difference with respect to minimum operating water amount and preset cock closing deciding water amount, is provided. CONSTITUTION:A water amount operating unit 161 operates a signal from a water amount detector 6 into water amount. Water amount signal is outputted into a water amount deciding unit 162 and servomotor drive circuit 17. The water amount deciding unit 162 outputs a combustion starting signal for a combustion control circuit 22 when the water amount is 2l/min or more and outputs a combustion stopping signal when the second set water amount Q2 is 1.5l/min or less. The water amount correcting unit 164 corrects the control water amount QO' operated in a controlled water amount operating unit 163. When the control water amount QO' is less than the second set water amount Q2 added with a given amount, the control water amount QO' is outputted into the servomotor drive circuit 17 as the fourth set water amount Q4, however, when the control water amount QO' is less than the third set water amount Q1, the same amount as the third set water amount Q2 is outputted into the servomotor drive circuit 17 while the control water amount QO itself is outputted into the servomotor drive circuit 17 in case the control water amount is except above cases.

This detected water W (Q) is a certain amount (for example, 2/m i

Then, the control water quantity (QO) is QO: 25XW/ (Tse

The water flow is adjusted by outputting a signal 1 (Q) and controlling the opening degree of the water control valve (9) via the servo motor (18).

By the way, in this type of instantaneous water heater that adjusts the amount of water to obtain hot water at a set temperature, the minimum operating water jJ1 (hereinafter referred to as the first set water h1 (Ql)) is determined and detected in consideration of safety. When the water ffl (Q) becomes less than the first set water value, it is necessary to stop combustion. Also, this first set water volume (Ql)
varies depending on the setting capacity (W) and the water supply temperature (Tin), and therefore needs to be determined by the following formula.

Q) may be less than the above water amount (Ql), so even if the amount of water is less than the water amount (Ql), it is not necessary to extinguish the fire immediately, but to wait for the water amount to recover for a certain period of time and then judge whether or not the fire can be extinguished.

However, if we wait for the amount of water to recover in this way, even if the hot water tap (10) is closed, combustion will continue for a certain period of time. j!/m1n) second set water volume (Q2)

In addition, in order to stabilize the control, the third set water volume (Q3) is set by multiplying the first set water volume (Ql), which is the minimum operating water volume, by a certain ratio (however, 1), and within the above certain period of time. If the water volume does not recover to the third set water volume (Q3), it is necessary to extinguish the fire.

As described above, in this type of instant water heater, as follows: (1) The first setting water 111 (Qll, the third setting water !I'< (Q3) is set by varying it according to the setting capacity, etc.).

■ Even if the detected water amount (Q) becomes less than the first set water amount (Ql), combustion continues for a certain period of time, and if the water amount (Q) does not recover to the third set water amount (Q3) or more, the fire is extinguished.

■ 検出水ffl (Q)が第2設定水量以下になれば

However, when the above control is performed, if the setting capacity (W) is set to a relatively high temperature on the small side, for example, W = 3.3, T
When setting in = 15'C5Tset = 65°C, the control water flow (QO) is 1.65 J! Therefore, the opening degree of the water control valve (9) is adjusted so that the water flow becomes 1.65 rpm, but as shown in Figure 3, due to overrun of the servo motor (18), etc. Control to open the water control valve (9) when the water volume temporarily falls below the second set water fit (Q2), which is the water level for determining open valves, and the fire is extinguished, making it impossible to release hot water, or when the fire is extinguished. Even if you do this, you will have to repeatedly extinguish the fire by igniting it.

If the control water is not restored to the 3 setting water tit (Q 3 ), the fire will be extinguished even if the control water is adjusted to (QO), which poses a problem in use.

FIG. 5 is a block circuit diagram of the arithmetic control section (16) in the present invention. The water amount signal is output to the water amount determining section [62] and the servo motor drive circuit (17). Water (111 constant parts (162
), the water 111 is, for example, 2. g/min or more, a signal to start combustion is output to the combustion control circuit (22), and if it is less than 1.51/min, which is the second setting water t11 (Q2), a signal to stop combustion is output. . Furthermore, when compared with the first set water volume (Ql) and the first set water volume (Ql) calculated together with the control water volume (QO) by the control water volume calculation unit (163), the water volume becomes less than or equal to the first set water volume (Ql). If the counter is activated, the water volume reaches the third set water volume (Ql) within a certain period of time.
If it does not recover, a combustion stop signal is output at the same time as the counter is increased. The water amount correction section (164) corrects the control water amount (QO) calculated by the control water amount calculation section (163) under certain conditions, and the control water amount (Q6) is
A certain amount (for example, 1.2 J/win) to the set water claw (Q2)
If the added water volume is less than the added water volume (for example, 2.71/min, this is referred to as the 4th setting water u (04)), the open side water volume (QO
) to the fourth setting water standard (Ql), and the above control water amount (qo)
If the above water 1-it is less than the third set water volume (ql), the water volume is equal to or more than the third set water volume (Ql),
In other cases, the control water ht (QO) is directly outputted to the servo motor drive circuit (17). For example, the feed water temperature (Tin) is 10°C, the setting capacity (W) is 6.6, and the set temperature (Tset) is 75°C.
℃, the control water (QO) is the third setting water + Xk

Therefore, according to this configuration, the controlled water amount (QO) is constant fi at the second setting water jTt (02) which is the open water determination water 11.
The water added by t is 11'L or more and the third setting water: A (Q
l) Since the water control valve (9), such as a servo motor, is set to the above value, it will not be judged as open due to an overrun during the design of the water control valve (9), and the water flow will be less than or equal to the first set water volume (Ql). There is no longer a situation in which the water does not recover to the third set water amount (Ql) or higher, and therefore, there is no possibility that rt' is unexpectedly changed to the hole 4S1, and the hot water supply characteristics do not deteriorate.
