Abstract

PROBLEM TO BE SOLVED: To suspend part of a power source to decrease power consumption when a water heater is not operating, by connecting a communication circuit respectively to a water heater control circuit and a remote control circuit, and supplying power source to the water heater control circuit and the communication circuit connected thereto respectively from a communication power source and a water heater power source. SOLUTION: In the case where the operation state of a water heater main body is operated into a waiting state (operation off state) by a remote controller 2, the operation off command is transmitted to a water heater communication circuit 4 of a water heater control circuit 1 incorporated in the water heater main body from a remote control circuit 7 of the remote controller 2 by means of a remote control communication circuit 8. A water heater power source 6 is controlled into a stopped state by a water heater control circuit 3, and the consumption of electric power is maintained to the minimum requirement. In the case of igniting and operating the water heater only when the hot water stopcock is opened, the water heater power source 6 is controlled into the operation state only when the water current is detected by a water current detection part 9 to maintain the water heater control circuit 3 in the operation state, thereby reducing the consumption of electric power in the operation on state.

A communication circuit for supplying power to the communication circuit connected to the water heater control circuit, and a water heater power supply for supplying power to the water heater control circuit.

[0006] When the main body of the water heater is set to the standby state by the remote control circuit, the power supply of the water heater is stopped, so that the power consumption of the power supply of the water heater can be reduced.

A water heater control circuit for controlling the water heater body, a remote control circuit for remotely controlling the water heater body,
It has a communication circuit respectively connected to the water heater control circuit and the remote control circuit.

[0008] When the remote control circuit sets the water heater main body in a standby state, the communication circuit is set to an intermittent operation state, so that power consumed by the communication circuit can be reduced.

Further, a water heater control circuit for controlling the water heater body, a remote control circuit for remotely controlling the water heater body, a communication circuit respectively connected to the water heater control circuit and the remote control circuit, A communication power supply that supplies power to the communication circuit connected to the water heater control circuit, a water heater power supply that supplies power to the water heater control circuit, and a water flow detection unit that detects water flowing through the water heater. is there.

When the water heater is turned on by the remote control circuit, the water heater is turned on when the water flow detector detects a water flow. However, since the water heater power supply is stopped until the water flow detector detects the water flow, the power consumption of the water heater power supply can be reduced.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a control device for a water heater according to an embodiment of the present invention. In the figure, 1 is a water heater main body control device built in a water heater main body (not shown), 2 is a remote control device for remotely controlling the device main body 1, 3 is a water heater control circuit, and 4 is A hot water heater main body communication circuit for communicating between the hot water heater control circuit 3 and the remote control device 2, a communication power supply 5 for supplying power to the hot water heater main body communication circuit 4, and a hot water supply 6 for supplying power to the hot water heater control circuit 3 A power supply 7, a remote control circuit for controlling the remote control device 2, a remote control communication circuit 8 for communicating between the remote control circuit 7 and the water heater control device 1, and a sensor 9 for detecting water flowing in the water heater main body. It is a water flow detection unit.

Next, the operation and the operation will be described. When the operation state of the water heater main body is set to the standby state (operation-off state) by the remote control device 2, the "operation-off" command from the remote control circuit 7 receives the remote control communication. It is transmitted to the hot water heater main body communication circuit 4 of the hot water heater main body control device 1 via the circuit 8. The hot water heater main body communication circuit 4 informs the hot water heater control circuit 3 that the operation is to be turned off, and the hot water heater control circuit 3 performs the process of “off operation” to turn off the water heater power supply 6. . Here, the hot water heater power supply 6 may be stopped by the hot water heater main body communication circuit 4. Further, if it is not necessary for the water heater control circuit 3 to perform the "operation off" process, the water heater power supply 6 may be stopped when the "operation off" command is transmitted from the remote control device 2. . Thereafter, when the operation state of the water heater main body is changed to the operation state (operating state) by the remote control device 2, the “operation start” command from the remote control circuit 7 is transmitted via the remote control communication circuit 8 to the water heater main body control device. 1 is transmitted to the water heater main body communication circuit 4. The hot water heater main body communication circuit 4 turns on the hot water heater power supply 6, activates the hot water heater control circuit 3, and operates the hot water heater main body according to signals from the remote control circuit 7 and various sensors in the equipment. It can be so. Further, in order to further reduce the power consumption when the operation state of the water heater main body is changed to the operation state (operating state) by the remote control device 2, the command from the remote control device 2 is issued only when the hot water tap is opened. In the mode in which the water heater only needs to perform the combustion operation, the water heater main body communication circuit 4 monitors the water flow detection unit 9 and when the water flow detection unit 9 detects the water flow, the water heater power supply 6 is turned on, and the water heater control is performed. The combustion operation is performed with the circuit 3 operating. Further, the communication between the water heater main body communication circuit 4 and the remote control communication circuit 8 is continuously operated in order to quickly display the remote control device 2 and quickly operate the water heater main body when the operation is in a running state. In the standby state (run-out state), communication is intermittently operated to reduce power consumption. The intermittent interval of the intermittent operation of the communication may be set to infinity, and the operation may be performed only when the remote control device 2 is operated. The information cannot be transmitted to the remote control device, and the usability is somewhat deteriorated.

[0014]

As described above, according to the present invention, when the water heater is in the standby state (operation cutoff state), only the minimum necessary power supply can be operated, so that power consumption can be reduced. .
