られる。As described above, the hot water supply device has an advantage that it is not necessary to prepare the control devices (6) of different types depending on the presence or absence of the remote control operating device (7). In the hot water supply device, when a power failure occurs during the hot water supply operation, the source gas valve (13) is de-energized and closed, and the combustion of the gas burner (10) is stopped. However, since the hot water tap (5) is still open and unheated water is being released, the main gas valve (13) is energized to open and open the gas burner (1
It is necessary to prevent abrupt combustion of (0) and secure a safe condition. Therefore, the following measures may be taken.

In the usage mode in which (7) is connected, the remote control operating device (7) and the microcomputer storing the operation signal of the operation switch (72) are naturally turned off after the power failure is recovered, so that the tap water faucet (5) is Even if it is in the open state, the main gas valve (13) is not energized, and although there is no concern that the gas burner (10) will suddenly burn, the hot water tap (5 ) Need to be cut off. That is, in the usage mode in which the remote control operating device (7) is connected, the remote control operating device is temporarily shut off after the tap water tap (5) is shut off after the power is restored.
Operate the operation switch (72) of (7) and then tap the tap again.
If (5) is not opened, hot water cannot be taken out, which complicates the operation.

Instead of), a water flow switch that turns ON / OFF depending on the presence / absence of water flow may be provided, and the ON / OFF signal of the water flow switch may be used to determine the open / closed state of the hot water tap (5) after a power failure recovery. In this case, when the hot water temperature sensor is arranged on the downstream side of the heat exchanger (4) and the hot water tap (5) is opened, the output of the hot water temperature sensor is used to feedback control the gas burner (10). Control the amount of combustion of and take out hot water at the set temperature.

号が出力される。The above technical means operates as follows. When the power failure occurred during the hot water supply operation (when the hot water tap is opened), the output of the remote control detection means is determined to determine whether or not the remote control operating device (7) is connected.
In addition, the output of the water flow detector that checks for the presence of water flow in the water passage (1) is judged to see if the inside of the water passage (1) is in a water-flowing state and the tap water tap (5) is left open. Determine whether or not. And, the remote control operation device (7) is not connected (the remote control detection means outputs a remote control absence signal) and the water flow detector outputs a water flow detection signal (the tap water faucet (5) is in an open state). If it is determined that the above), the AND circuit to which both of these signals are applied outputs an abnormal signal.

In the case of the usage mode in which the remote control operating device (7) is connected: When the remote control operating device (7) is connected, the "remote control no signal" is output from the remote control detection means when the power is restored.
Is not output, the abnormal signal is not output from the AND circuit that outputs the abnormal signal under the condition that the signal is generated. On the other hand, since the remote control operating device (7) returns to the initial state (state when the power supply is connected) when the power is restored, the hot water supply device does not come out unless the operation required for hot water supply operation is performed again by the remote control operating device (7). Not possible. That is, when the remote control operating device (7) is connected, the remote control operating device (7) is operated even if the tap water faucet (5) is open and the water flow detector outputs a water flow detection signal. Unless it is done, the gas burner (10) for hot water supply does not burn.

In the case of usage without connecting the remote controller (7) In the usage without connecting the remote controller (7), the "remote controller no signal" is output from the remote controller when the power is restored, and under such conditions the water flow detector If the water flow detection signal is output from the AND circuit, an abnormal signal is output from the AND circuit. When the abnormal signal is output, the gas burner (10) is kept in the combustion prohibited state, so in this state the hot water tap (5) is closed so that the water flow detector does not output the water flow detection signal. To Then, the abnormal signal from the AND circuit disappears and the hot water supply control is enabled. That is, once close the hot water tap (5) and then tap the hot water tap again.
When (5) is opened, the hot water discharge operation starts, and the gas burner for hot water supply burns only at this time.

When the hot water supply device is connected to an electric outlet to supply electricity, it is determined whether or not the remote control operating device (7) is connected (see step (80) in the drawing). (I). Next, when the remote control operating device (7) is connected, it is monitored that the operation switch (72) arranged in the remote control operating device (7) is turned on (step of reference numeral (81)). When the operation switch (72) is turned on, the set temperature set by the temperature setting button (71) of the remote control operating device (7) is stored in the microcomputer as a tap water temperature (T) (reference numeral (82)). See step). (C). Next, the measured flow rate (flow rate per unit time) of the flow rate counter (2) is monitored (see the step of drawing code (83)), and the measured flow rate of the flow rate counter (2) is not "0" and the tap ( If the 5) is judged to have been opened, the original gas valve
Energize (13) and keep it open to keep the gas burner (1
0) (see step (84)). (D). Hot water temperature (T) read in the microcomputer in the step of the drawing code (82), water temperature of the water passage (1) detected by the temperature sensor (3), and further the heat exchanger (4) Based on the heat exchange efficiency, etc., the feed-forward control of the combustion amount of the gas burner (10) is performed so that the hot water at the outlet temperature (T) is boiled in the heat exchanger (4) part (see the step of the drawing code (85)). ..
That is, in order that the hot water at the tapping temperature (T) is boiled in the heat exchanger (4), the gas circuit (1) to the gas burner (10)
The opening of the proportional valve (12) inserted in (1) is controlled. (E). During the hot water supply operation, the output of the flow rate counter (2) is continuously monitored (see the step of drawing code (86)), and when the measured flow rate of the flow rate counter (2) is "0", the tap water faucet (5 ) Is closed, the main gas valve (13) upstream of the proportional valve (12) is de-energized and closed to maintain the gas burner (10) in a fire extinguishing state ( Drawing code (8
See step 7)).

ることとなる。Now, while the hot water supply operation is being continued while monitoring whether or not the measured water amount of the flow rate counter (2) is "0", that is, the steps of the reference numerals (85) (86) are repeatedly executed. If a power failure occurs during the operation, the electric power supply to the control device (6) and the remote control operation device (7) is stopped. Therefore,
The power supply to the main gas valve (13) is also stopped and the gas burner (10) is put into a fire extinguishing state. At this time, the tap water tap (5) remains open. Then, when the power failure is restored, the control device (6)
Also, the power supply to the remote control operation device (7) is restarted, and the control operation starts again from the step of the reference numeral (80), until the operation switch (72) of the remote control operation device (7) is turned on. 72) Monitor the input. That is, after the power failure is restored, unless the operation switch (72) is turned on, the main gas valve (13) is not energized and the gas burner (10) is not ignited even if the hot water tap (5) is open ( Drawing number (84)
Step is not executed). This can prevent the risk of sudden combustion of the gas burner (10) when the power is restored.
