Abstract

PURPOSE:To prevent reboiling during suspension by providing a timer which is dapted to start action after having received a stop hot-water supply signal from a remote control device and output a close signal to an electric open/close means after specified time. CONSTITUTION:When a switch 7 is turned OFF in order to stop the supply of hot water, this signal forces a hot-water supply device 1 to stop combustion immediately and put the device into stop status. An indicator 8 puts out light, thereby indicating the stop of combustion. On the other hand, an OFF delay timer 10 receives a signal to stop the supply of hot water from a switch 7, starts action, and outputs a close signal to a motor-driven valve 5 after a specified time. Therefore, the motor-driven valve 5 turns into a closed status after the lapse of a specified time since the hot-water supply device 1 comes to a halt. Having received a closed signal from the OFF delay timer 10, a second indicator 9 puts out light, then indicates that the motor-driven valve 5 is under closed state. During the suspension of hot-water supply, hot water is supplied by the OFF delay timer 10 as described above. In other words, under the condition where water is flowing into the hot-water supply device 1, the hot-water supply device 1 stops the operation, thereby eliminating the reboiling observed in the prior art devices, that is, the rise in the temperature of hot water.

Here, the instantaneous gas water heater 1 will be explained in more detail below. This type of water heater detects the flow of water to start and stop combustion, but especially when stopped, it detects that the amount of water has reached the amount of extinguishing water and stops combustion. When the water heater is stopped, the temperature of the hot water rises due to a delay in detection by the water amount detection means that detects the amount of water, the heat capacity of the heat exchanger in the water heater, etc., which is called after-boiling. This rise in the temperature of the water, or post-boiling, depends on the speed at which the water volume stops, and the temperature rises rapidly.
, - becomes larger when the opening/closing means is closed. This after-boiling will appear as a large rise in water temperature the next time the opening/closing means is opened, making it inconvenient to use and posing a risk of burns.

Operation With the above configuration, when the user inputs a hot water supply stop signal using the input means of the remote controller to stop hot water supply, the water heater immediately stops combustion upon receiving the hot water supply stop signal from the input means. Further, the timer starts operating upon receiving the hot water supply stop signal, and outputs a close signal after a predetermined time. The electric opening/closing means operates upon receiving this closing signal and enters the closed state. In other words, the timer delays the closing operation of the electric opening/closing means, causing the water heater to stop combustion while water is flowing, and prevents the after-boiling that occurs when conventional water heaters stop. .

To the electric opening/closing means 5 which performs opening/closing operations based on electrical signals.
2 is an electric valve. Reference numeral 6 denotes a remote control, which is operated by the user, and includes a switch 7 as an input means whose on/off corresponds to the start/stop of hot water supply, and a display 8 as a notification means that responds to the on/off of the switch 7 and notifies the outside of the state of the switch. , a second indicator 9 is provided as a second notification means for notifying the state of the electric valve 5 to the outside. A timer 1o is an off-delay timer that starts operating upon receiving an off signal from the switch 7 of the remote controller 6, that is, a hot water supply stop signal, and outputs a closing signal to the electric valve 5 and the second display 9 after a predetermined time. The off-delay timer 10 delays only the hot water supply stop signal from the switch 7, and immediately outputs an open signal to the electric valve 5 and the second display 9 without delay when the hot water supply start signal is input from the switch 7. The water heater 1 is configured to receive hot water supply start and stop signals from a switch 7.
