However, in this conventional device, the remote control and the main body are each provided with clock timing means, and the time on the main body side is changed by unilaterally sending the time from the remote control side to the main body side. Because it was
It had the following problems.

That is, when the time on the remote controller side is not normal, even if the time on the main body side is normal, both times are automatically incorrect, so that the time is set normally by the user's time setting operation. I had to bring it back. Further, in this conventional device, the time setting operation by the user can be performed only from the remote controller side, and not from the main body side.

The present invention includes a plurality of time generation units and a time display unit, and in a device control system for performing a predetermined timer control at a preset time, the time at which the timer control is performed and the display time. It is an object of the present invention to prevent the user from being confused due to the disagreement and to improve the operability of the user when the occurrence time of the time generating unit is not normal.

[0006]

Means for Solving the Problem and Its Action / Effect The control system for a device according to the present invention is provided with time selecting means for selecting an effective time from among the times generated by a plurality of time generating sections. If the time is not normal and the other is normal, the time on the normal side is not lost by the time on the abnormal side and is retained as a valid time, eliminating unnecessary time adjustment operations by the user. . Furthermore, by providing a time control means for using this effective time for the display time of the time display unit and the timer control, it is possible to prevent the user from being confused due to the discrepancy between the display time and the timer control time.

Further, in the equipment control system according to the present invention, a plurality of operating parts and time display parts are provided corresponding to the time generating parts, and the time selecting means is operated when the operating parts are operated. By configuring the time of occurrence of a valid time to be set, the time of that time generating section can be set by any operation section, and the time of other time generating sections can be automatically adjusted. The operability when setting the time is improved.

Further, in a device control system in which a time generation unit, a time display unit, and an operation unit are respectively provided in a plurality of remote operation units for remotely operating the device body, the remote operation units are arranged at a distance from each other. Therefore, if it is possible to set the time only from one of the remote operation units, it is necessary to move to the remote operation unit every time the time is set. Since the time can be set even from, such a problem is solved.

In the device control system according to the present invention, when the selected time is reset due to a power failure or the like and is not normal, if the time of the other time generating unit is normal, this time is set. By newly selecting, the time setting operation by the user can be omitted. still,
Regarding whether or not the occurrence time is normal, whether or not a power failure has occurred, whether or not the time has been reset (ex. In the case of the specification that it is 00:00 when reset), and whether or not there is time data (ex After the power failure, in addition to the judgment based on (in case of the specification of: ---), etc., when there are three or more time generation units, it may be decided by a decision such as a majority vote.

Further, in the device control system according to the present invention, the time of the remaining time generator is the same as the valid time even when the valid time generator is disconnected from the system. , The timer control will not be disabled and the display time will not change suddenly.

BEST MODE FOR CARRYING OUT THE INVENTION A hot water supply apparatus will be described below as an embodiment of an apparatus control system to which the present invention is applied.

[00012] FIG. 1 is an overall configuration diagram of a hot water supply apparatus, which includes a water heater main body 1 and a water supply pipe 2 for supplying water to the water heater main body 1.
, A hot water supply pipe 3 for drawing hot water from the water heater main body 1, a bathroom shower faucet 4 and a kitchen faucet 5 respectively branched from the hot water supply pipe 3.
And a signal between the bathroom remote controller 6 provided near the bathroom shower faucet 4, the kitchen remote controller 7 provided near the kitchen faucet 5, the bathroom remote controller 6 and the kitchen remote controller 7, and the water heater body 1. A remote control line 8 for transmission is shown.

Each of the remote controllers 6 and 7 has a control SW (not shown) for transmitting a control signal such as a set temperature to the water heater main body 1, an ON / OFF switching SW 9 for a time setting mode, and a time setting. SW10, a display unit 11 for displaying various information,
And a microcomputer 12 having a built-in time generator, and the time setting SW 10 is an up SW 1
0a and the down switch 10b, and the display unit 11 includes a temperature display unit 11a that displays the set temperature and a time display unit 11b. Further, each of the remote controllers 6 and 7 is provided with a time reservation SW for timer control (not shown), and is configured to transmit the reservation time by the time reservation SW operation to the water heater main body 1.

In the water heater main body 1, various loads are controlled according to control signals transmitted from the remote controllers 6 and 7, and various loads are controlled in accordance with reservation time and time information transmitted from the remote controllers 6 and 7. Control device 13 for timer control
Is provided.

The control regarding the time of the hot water supply device having the above configuration will be described step by step.

FIG. 2 shows a flow relating to time display of the bathroom remote controller 6 and transmission of the time information. First, whether the kitchen remote controller is connected (S1), or the connected kitchen remote controller 7 has a time generator. It is confirmed (S2), and if the kitchen remote controller 7 having the time generation unit is not connected, the operation of the ON / OFF switching SW 9 and the time setting SW 10 in the time setting mode (hereinafter referred to as the time setting operation). ), The occurrence time is changed according to the operation content (S
3) After transmitting the occurrence time to the control device 13 of the water heater main body 1 (S4), the occurrence time is displayed (S5), and the process ends. On the other hand, when the kitchen remote controller 7 having the time generator is connected, a subroutine described later is executed (S6), and the process proceeds to S5.

The reason for performing such processing is that when both the bathroom remote controller 6 and the kitchen remote controller 7 have a time generation unit, it is necessary to determine which generation time should be used based on various conditions. This is not necessary when 7 is not connected or when the kitchen remote controller 7 having no time generator is connected.

Next, the bathroom remote controller 6 which is executed when the kitchen remote controller 7 having a time generator is connected.
The subroutine (S6) will be described with reference to FIG.

First, it is confirmed whether or not it is within a predetermined time after the time setting operation on the bathroom remote control 6 side is performed (S7), and if it is not within the predetermined time, it is confirmed whether or not there is a transmission time from the kitchen remote control 7 ( S8) If there is no transmission time, it is confirmed whether the time is set after the power is turned on (S9). If the time is set, the occurrence time is transmitted to the kitchen remote controller 7 and the controller 13 of the water heater main body 1 ( S10), if the time has not been set, the process ends.

In the above process, when the bathroom remote controller 6 has already set the time, but the kitchen remote controller 7 has not set the time, the kitchen remote controller 7 sets the generation time according to the transmission time from the bathroom remote controller 6, and the bathroom remote controller 7 6 and the kitchen remote controller 7 have no time set, it means that the time is not adjusted by transmitting the occurrence time. And the bathroom remote control 6,
If the kitchen remote control 7 is not set to the time, the above-mentioned S
5, meaningless contents such as "---:" are displayed.

On the other hand, if it is confirmed in S8 that there is a transmission time from the kitchen remote controller 7, the generation time of itself is set in accordance with this transmission time (S11), and the process is terminated. This means that regardless of whether or not the bathroom remote controller 6 has already set the time, if the kitchen remote controller 7 has already set the time,
This shows that the generation time on the bathroom remote control 6 side is set in accordance with the transmission time from the kitchen remote control 7.

If it is confirmed in S7 that the time is within the predetermined time after the time setting operation, the time of occurrence is set according to the operation contents (S12), and the kitchen remote controller 7 indicates that the time setting operation is in progress. After sending to (S13), S10
Go to to send the time of occurrence. As will be described later, when the kitchen remote controller 7 receives the fact that the bathroom remote controller 6 is in the time setting operation, it sets the occurrence time according to the transmission time from the bathroom remote controller 6.

This process sets the generation time of the kitchen remote controller 7 in accordance with the transmission time from the bathroom remote controller 6 during the time setting operation of the bathroom remote controller 6 regardless of whether the kitchen remote controller 7 has already set the time. It is shown that. That is, by performing such processing, it is possible to prevent the time setting performed by the bathroom remote controller 6 from being lost due to the occurrence time transmitted from the kitchen remote controller 7.

Next, FIG. 4 shows a flow relating to time display of the kitchen remote controller 7 and transmission of time information. First, it is confirmed whether or not a time setting operation has been performed (S14). Is in the time setting operation (S15), and if it is not in the time setting operation, it is confirmed whether the time is set after the power is turned on (S16). If there is no time after the power is turned on, the bathroom remote control 6 (S17), and if there is a transmission time, set its own generation time according to this transmission time (S17).
18), the generation time is displayed (S19), the process is terminated, and if there is no transmission time from the bathroom remote controller 6, S19
Go to and display the time of occurrence.

In the above process, when the bathroom remote controller 6 has already set the time, but the kitchen remote controller 7 has not set the time, the kitchen remote controller 7 sets the generation time according to the transmission time from the bathroom remote controller 6, and the bathroom remote controller is set. 6 and the kitchen remote controller 7 have no time set, it means that the time is not adjusted by transmitting the occurrence time. The display content of S19 in the latter case is similar to that described in the process after S9 of the bathroom remote controller 6.

On the other hand, if there is a time setting after the power is turned on in S16, after the generation time is transmitted to the bathroom remote controller 6 and the controller 13 of the water heater main body 1 (S20),
Proceed to S19 to display the time of occurrence. This means that when the kitchen remote controller 7 has already set the time, regardless of whether or not the bathroom remote controller 6 has already set the time, the generation time on the bathroom remote controller 6 side is set in accordance with the transmission time from the kitchen remote controller 7. That is, in the steady state, the generation time of the kitchen remote controller 7 is prioritized over the bathroom remote controller 6.

Further, in S15, the bathroom remote controller 6
Is in the process of setting the time, the process proceeds to S18 and sets its own occurrence time according to the transmission time of the bathroom remote controller. The reason for doing this is that S13 of the bathroom remote controller 6 is used.
This is the same as described above.

If there is a time setting operation in S14, the generation time is set according to the operation contents (S21), and the process proceeds to S20 to control the bathroom remote control 6 and the water heater body 1. It is transmitted to the device 13.

Next, the flow of the control device 13 of the water heater main body 1 will be described with reference to FIG.

First, it is confirmed whether or not there is a transmission time from the kitchen remote controller 7 (S22). If there is a transmission time, the timer is controlled in accordance with this transmission time (S23), and the transmission time from the kitchen remote controller 7 must be reached. For example, check whether there is a transmission time from the bathroom remote controller 6 (S24), and if there is a transmission time,
Timer control is performed according to this transmission time (S25).
On the other hand, if there is no transmission time from either the bathroom remote controller 6 or the kitchen remote controller 7, the timer control cannot be performed, and the process ends.

Although the bathroom remote control 6 and the kitchen remote control 7 each have a time generation unit, the bathroom remote control 6 and the kitchen remote control 7 each have a time generation unit and a hot water supply. It goes without saying that the invention can also be applied to a device having a time generation unit in the main body.
