2a, a part of the water supplied from the supply pipe 31 is led to the hot water supply pipe 31a via the heat exchanger 32, and the remaining part is led to the hot water supply pipe 31a via the bypass pipe 32a. A bypass valve 33 is provided at the downstream confluence section, and mixes the water heated by the heat exchanger 32 and the water directly guided through the bypass pipe 32a by appropriately adjusting the ratio thereof.

On the other hand, a water flow control valve 34, a water flow sensor 35, and an inlet water temperature thermistor 36 are installed in the supply pipe 31 from the upstream side, a heat exchange thermistor 37 is installed downstream of the heat exchanger 32, and an outlet water temperature thermistor 38 is installed in the hot water supply pipe 31a. are provided for each.

The bypass valve 33 and the water flow control valve 34 are each driven by a geared motor provided therein, and their positions are detected by a potentiometer (not shown).

Further, the water flow sensor 35 outputs a number of pulses corresponding to the number of revolutions of an impeller (not shown) that is rotated by the water flow passing through the supply pipe 31 .

The control device 40 mainly includes a microcomputer with a custom IC equipped with a storage device containing programs and data necessary for its operation, an interface for signal exchange with each of the above parts, a safety circuit, and a power supply circuit. The system starts the operation of the gas water heater in a predetermined sequence, and also controls the combustion amount and water amount based on the signals from each controller 50.60, each thermistor 36, 37, 38, and water flow sensor 35. conduct.

These controls include an inlet water temperature thermistor 36, a heat exchange thermistor 37, each controller 50, 60, and a water flow sensor 3.
Feedforward control is performed to preliminarily control the combustion amount and water amount using the signal from 5, and feedback control is performed to correct the combustion amount and water amount control using the outlet hot water temperature thermistor 38 when predetermined conditions are met.

Further, the control device 40 is a control means of the present invention, and controls the gas water heater based on the operation signal from the controller that is operated first among the controllers 50 and 60, and further controls the operation of the gas water heater. A display signal is sent to each controller 5o, 6o to indicate the inside.

This display signal is such that different signals are sent to the operated controller and the non-operated controller, indicating whether or not the gas water heater is being operated by the controller at hand. This makes it easy for users to identify.

Furthermore, even if an abnormality occurs in the operation of the gas water heater, a predetermined signal is sent to notify the user of the abnormality, and each controller 50, 60 displays a predetermined display.

The main controller 50 and the sub-controller 60 are for setting and operating the operating state of the gas water heater, and are operated by operation switches 51, 61, . A water temperature setting volume 52.62 and a combustion lamp 53.63 indicating that the gas water heater is in operation are provided. Each of the combustion lamps 53 and 63 is designed to turn on at different times depending on the operating state of the gas water heater.

In this example, when the gas water heater is operating normally, the combustion lamp of the operated controller lights up continuously as shown by line A in Figure 2, and the combustion lamp of the unoperated controller lights up continuously as shown in line A in Figure 2. As shown in B, the light blinks intermittently. Further, in the event of an abnormality, all combustion lamps flash at shorter intermittent intervals than line B, as shown by line C.

Therefore, the user can easily know the operating state of the gas water heater by the lighting state of the combustion lamp.

The gas water heater of this embodiment having the above configuration operates as follows.

When the user turns on the operation switch of one of the controllers, sets the hot water temperature, and operates a faucet (not shown), the combustion fan 12 starts rotating, and
Water supplied by the supply pipe 31 is supplied through a water flow control valve 34,
The water passes through the water flow sensor 35, flows into the heat exchanger 32 and the bypass pipe 32a, the outflow amount of which is adjusted by the bypass valve 33, and flows out from the hot water supply port (not shown) via the hot water supply pipe 31a.

Then, the pulse signal transmitted from the water flow sensor 35 is transmitted to the control device 40.

When a predetermined number or more of transmitted pulse signals are detected, the control device 40 activates the sparker 1 to ignite the combustor 10.
4. Perform spark discharge.

When a spark discharge from the sparker 14 is detected by an operation detection section (not shown), the control device 40 changes the original solenoid valve 21 and the main solenoid valve 22, which have been in the closed state, to the open state.

Then, the fuel gas passes through the main solenoid valve 21, the main solenoid valve 22, and the proportional valve 23, is ejected from the nozzle 13, is mixed with combustion air, and is supplied to the burner group 11, where it is supplied to the already operating sparker. ignited by 14.

When ignition is detected by the flame rod 15 and a flame detection signal is sent out, detection signals from the inlet water temperature thermistor 36, heat exchange thermistor 37, exit hot water temperature thermistor 38, and water flow sensor 35 and the operation The required combustion amount is calculated based on a setting signal from the controller, and the combustion fan 12, proportional valve 23, switching valve 24, bypass valve 33, and water flow control valve 34 are controlled based on the calculation result. Further, after ignition, correction control of the air-fuel ratio is also performed based on a signal from the thermocute 16.

Thereafter, if there is a change in the amount of hot water or the set temperature, the ratio of the flow rate passing between the heat exchanger 32 and the bypass pipe 32a and the combustion amount by the bypass valve 33 are changed in accordance with the change.

At this time, the combustion lamp of the operated controller lights up continuously as shown by line A in Fig. 2, and the combustion lamp of the non-operated controller lights up continuously as shown by line B in Fig. 2. Blinking lighting is performed at large intermittent intervals.

Therefore, when another person attempts to operate the gas water heater using a controller that is not being operated, it can be easily determined that the gas water heater is already operating by operating another controller.

Also, if these controllers are installed in the bathroom and kitchen, for example, when you go to check the hot water heater 1 in the bathroom, you can see at a glance which controller is operating the gas water heater, so try operating it. This eliminates the inconvenience caused by misunderstandings such as not being able to operate the system.

In the above embodiments, the operation display device of the present invention was shown as an example provided for operating and driving equipment; however, it does not necessarily have to directly operate equipment; for example, In the operating lamp etc. indicating the connection with the outside line on the home telephone, the telephone connected to the outside line,
It can also be used as a display device to distinguish between unconnected telephones.

In addition, in the case where the operation of the 8!1 device is displayed on a display panel such as a liquid crystal display panel, it is possible to indicate the operating section operated more specifically.

Further, the number of operating means is not necessarily limited to two.
