When the clock time is set by the clock time setting means 4, the clock count is started by the clock time counting means 5.

Next, in order to set the reservation time, the reservation time setting switch 6 in the remote controller 2a is operated, the setting contents are detected by the reservation time setting means 7, and the reservation time is set.

When the reservation time is set by the reservation time setting means 7, the clock time counting means 5 and the reservation time of the reservation time setting means 7 are compared with each other, and it is determined whether or not a predetermined time before the reservation time has elapsed. Means 8 starts the determination.

Until the clock time becomes a predetermined time before the reserved time, the reserved driving standby mode is set, and the standby state of the reserved driving operation is set.

During this time, the operation switch 10 in the remote controller 2a
Is turned off, the OFF information of the operation switch is sent to the reserved operation holding means 11 and the combustion control means 9 to hold the reserved operation standby mode, and the operation of the combustion control means 9 is stopped.

When the count of the clock / time counting means 5 reaches a predetermined time before the reservation time, the reservation operation start means 8 sends the combustion control means 9 an ON signal of the operation switch and a reservation signal. Output the operation start signal,
The combustion control means 9 performs a predetermined combustion operation (for example, a warming operation of the hot water supply side heat exchanger).

As described above, the reserved operation holding means 11
Since the reserved operation standby mode is maintained even when the operation switch 10 is turned off, the reserved operation can be continued.

During this time, even if the operation switch 10 is turned on again, the reserved operation standby mode is maintained and the reserved operation can be continued.

(Embodiment 2) FIG. 2 is a block diagram relating to a reservation operation control device for a water heater according to Embodiment 2 of the present invention.

Referring to FIG. 2, only the differences from the first embodiment will be described. Reference numeral 1b denotes a reserved operation control device, and 12 denotes an operation for storing the start of the reserved operation from the OFF state of the operation switch 10 at the start of the reserved operation. The off storage means 13 is a timer means for counting a predetermined time starting from the storage time of the operation off storage means 12 and judging the elapse of the predetermined time, and 1 is the operation off storage means when the predetermined time of the timer means 13 has elapsed. Operation stop means for automatically turning off the operation switch based on the memory indicating that the operation has been turned off.

As for the operation, only the differences from the first embodiment will be described. When the operation switch 10 is turned off during the reserved operation standby mode by the reserved operation start means 8, the reserved operation standby mode is held by the reserved operation holding means 11,
Wait for the start of reserved driving.

Next, the reserved operation start means 8 outputs the reserved operation start signal and the ON signal of the operation switch, and stores the fact that the operation switch 10 is in the OFF state in the operation OFF storage means 12.

Starting from the time stored by the operation-off storage means 12, the timer means 13 starts counting a predetermined time. The timer means 13 counts a predetermined time (exceeding the time when the reserved operation has been completed, for example, 24 hours), and when the predetermined time has elapsed, notifies the operation-off storage means 12 that the time has elapsed.

The operation-off storage means 12 includes a timer means 13
When the predetermined time elapses, an instruction is output to the operation stopping means 14 to automatically turn off the operation switch.
Then, the operation stopping means 14 informs the combustion control means 9 that the operation switch is turned off, and the water heater is brought into an operation stopped state.

As described above, even when the reserved operation is started from the off state of the operation switch 10, the operation switch can be automatically turned off a predetermined time after the start of the reserved operation.

Here, an example is given as the predetermined time,
The operation of turning off the operation switch and the like at the time when the reserved operation starts and the reserved time comes and the reserved operation ends, that is, without a predetermined time, can be easily realized by a program such as a microcomputer.

(Embodiment 3) FIG. 3 is a block diagram relating to a reservation operation control device for a water heater according to Embodiment 3 of the present invention.

In FIG. 3, only the differences from the second embodiment will be described. 1c is a reserved operation control device, 15 is a switch operation detecting means for detecting a switch operation of a remote controller 2a such as a clock time setting switch 3, and 16 is a hot water supply. A flow sensor configured to detect a flow rate inside the vessel, a hot water tap detecting means 17 for detecting a flow rate equal to or more than a predetermined amount of the flow sensor 16, a detection signal C1 of a switch operation of the switch operation detecting means 15, or a hot water supply Detection signal C of plug use detection means
2 is an operation stop canceling unit that clears the memory of the operation-off storage unit 12 and does not turn off the operation switch after a predetermined time of the timer unit 13 has elapsed.

As for the operation, only the differences from the second embodiment will be described. When the timer unit 13 counts a predetermined time when the reserved operation is started from the OFF state by the reserved operation holding unit 11 and the reserved operation start unit 8, the switch operation detecting unit 15 detects all the contents in the remote controller 2a. (For example, a set temperature changeover switch, a priority switch, etc. (not shown)) are monitored. When the switch operation detecting means 15 detects that any switch of the remote control 2a has been operated, the detection result C1 is sent to the operation stop canceling means 18, and the operation stop canceling means 18 reads "operating switch of the operation off storage means 12 The reserved operation has been started from the OFF state. "

When the memory in the operation-off storage means 12 is cleared, the operation-off storage means 12 instructs the operation stop means 14 to turn off the operation switch even if a predetermined time has elapsed by the timer means 13. The operation of automatically turning off the operation switch without outputting a signal to perform the operation becomes invalid.

Next, when the flow rate sensor 16 and the hot water tap use detecting means detect that a flow rate of a predetermined amount or more has flowed into the water heater, a detection result C2 is sent to the operation stop canceling means 18 and the operation stop canceling means 18 is sent. Reference numeral 18 similarly clears the storage of "the reserved operation has been started from the operation switch OFF state" in the operation-off storage means 12.

The operation after the memory is cleared is the same as that at the time of detection of the switch operation, and will not be described.

As described above, by detecting the operation of any switch of the remote controller 2a or detecting the use of the hot water tap,
By detecting that the user is at home, the operation of automatically turning off the operation switch after a predetermined time can be invalidated.

(Embodiment 4) FIG. 4 is a block diagram relating to a reservation operation control device for a water heater according to Embodiment 4 of the present invention.

Referring to FIG. 4, only the differences from the third embodiment will be described. 1d is a reserved operation control device, 2b is a remote controller of a wireless communication system, 19 is a monitor of the electric energy of the battery, and it is below a operable limit value. A power drop detection means for determining a power drop at the time; a set temperature switching means for switching the set temperature of the water heater to a predetermined setting in response to the power drop detection result of the power drop detection means; Reference numeral 21 denotes a predetermined set switching pattern of the set temperature switching means 20. At this time, a set temperature specific change detecting means for detecting that the user does not perform a switch operation, and 22 is excluded by the set temperature specific change detecting means 21. The operation-off storage unit 1 receives only the user operation detection signal C1
Operation stop cancellation means for clearing the memory of No. 2.

As for the operation, only the differences from the third embodiment will be described. The remote controller 2b of the wireless communication type generally uses a dry battery as a power source, and uses the power amount as a power amount detection unit 1.
9 is constantly monitoring. Then, when the amount of power falls below the operable limit value, a decrease in the amount of power is determined and transmitted to the set temperature switching means 20.

When the set temperature is equal to or higher than the predetermined temperature (for example, when setting a high temperature equal to or higher than 60 ° C.), the set temperature switching means 20 cannot be operated by the remote controller 2b due to a decrease in the power of the dry battery. Is automatically switched to a predetermined temperature (for example, 47 ° C.).

The switching of the set temperature switching means 20 from the high temperature setting to the predetermined set temperature is transmitted to the water heater as a switch operation signal, and is determined by the switch operation detection means 15.

The switching operation of the set temperature detected by the switch operation detecting means 15 is changed by the set temperature specific change detecting means 21 into a change pattern of the set temperature at the time of a decrease in the electric energy (for example, a change from 60 ° C. to 47 ° C.). That is, it is determined that the set temperature is not switched by a user operation.

Therefore, the operation pattern other than the user operation is excluded by the set temperature specific change detecting means 21.
Only the user operation signal C1 is transmitted to the operation stop cancellation means 22.

The operation after the signal C1 is transmitted to the operation stop canceling means 22 is the same as that of the third embodiment, and the description is omitted.

Although the above description has been made of the embodiment in which the specific change in the set temperature is detected and the power amount of the remote controller 2b is judged to be lower, information indicating the lowering of the power amount is separately included in the message of the wireless communication. If it is added, it is sufficient to judge only the power reduction information, not the specific pattern of the switch operation, and the configuration can be further simplified.

As described above, the remote controller 2 of the wireless communication system
The operation of automatically switching the set temperature when the amount of power of the dry battery decreases in b can be distinguished from the user operation, and the OFF function of the operation switch after a predetermined time can be enabled.

[0062]

As described above, according to the present invention, even if the operation switch is turned off, the reserved operation standby mode is maintained, so that even if the operation switch is turned on again, the re-operation of the reserved operation is unnecessary. In addition, even if the operation switch remains off, the operation switch is automatically turned on and the reservation operation is started when the predetermined time before the reservation time is reached, so that the operability of the switch and the usability of the reservation operation function are improved. Can be.

In addition, when the reserved operation is started with the operation switch turned off, the operation switch is automatically turned off after a predetermined time, so that the user's leaving for a short time is unexpectedly extended, and the absence period increases. Also, since the operation switch is turned off, it is possible to provide the user with security and security.

Further, during a period in which the reserved operation is started with the operation switch turned off and the operation switch is turned off after a predetermined time, a user's switch operation and use of a hot water tap are detected, and it is determined that the user is at home. The automatic turning off operation of the operation switch can be disabled, and when the user is at home, for example, when the user tries to use the water heater, the operation switch can be prevented from being automatically turned off, further improving the usability. can do.

Further, even when the battery power of the remote controller of the wireless communication system decreases and the set temperature is automatically switched to a predetermined setting, a change in the set temperature of a specific pattern when the battery power is reduced is detected. Since we do not judge it as user use,
Even if the battery power drops during the absence period of the user and the set temperature is automatically switched, the operation of the operation switch for a predetermined time is not invalidated because it is not determined as a user operation, and after a predetermined time, The operation switch can be turned off without fail, and the user can be provided with more safety and security.
