Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a control device that automatically turns on and off combustion appliances such as automatic bathtubs with water heaters and space heaters by setting a timer reservation time.

(Prior Art) Conventionally, control devices for combustion appliances such as automatic bath pots with water heaters and space heaters have been installed not only in the kitchen where the water heater is installed, but also in other places such as bathrooms and shower rooms. Some are equipped with separate remote controllers. In conventional control devices of this kind, one of the plurality of remote controllers has a clock function so that a reserved time can be set, but the other remote controllers do not have a clock function. In other words, in the conventional remote controller, only one remote controller is provided with a clock control unit and a time display (hereinafter, this remote controller will be referred to as the main remote controller), and other remote controllers (hereinafter, this remote controller will be referred to as the main remote controller). The remote controller (hereinafter referred to as a sub-remote controller) was not equipped with a clock control section or the like.
Therefore, conventionally, it was not possible to check or set the current time or reserved time on the sub-remote control side.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to enable a sub-remote controller to check the reserved time set by the main remote controller and also to set the reserved time.

(Means for Solving the Problems) In order to achieve the above object, the present invention adopts the following configuration.

That is, in the combustion appliance control device of the present invention,
A main remote controller and a sub-remote controller are each connected via a signal transmission line to the main controller that controls the combustion of combustion appliances such as bathtubs, and each of the main and sub-remote controllers can operate the time display and timer reservation time setting. Further, the main remote controller has a clock control section, and the main controller controls the timer reservation time setting output signal from one of the main and sub remote controllers to control the main remote controller's clock. The present invention is characterized in that it includes a transmission control section that transmits a reserved time output signal set by the clock control section to the time display section of each remote control as well as to the control section.

(Operation) In the above configuration, the scheduled time is set by operating the scheduled driving time setting means of each remote controller. The data on the set reservation time is transmitted to the transmission control section of the main body controller via the signal transmission line, and further transmitted from the transmission control section to each remote controller via the signal transmission line. As a result, the reserved time is displayed on each time display of the main remote controller and the sub remote controller.

(Example) In this example, a case where an automatic bathtub with a water heater is used as a combustion appliance will be explained. FIG. 1 is a configuration diagram of a control device for an automatic bathtub with a water heater. In the figure, 1 indicates the entire control device,
2 is a main controller for controlling combustion, 4 is a main remote controller, and 6 and 8 are sub remote controllers.

The above-mentioned main body controller 2 includes a sequence control section 9, a transmission control section 10, and each remote control 4, 6,
The combustion control unit 12 includes a combustion control unit 12 that controls combustion of the automatic bath pot based on the signal transmitted from the bath heater 8. A main remote controller 4 and sub remote controllers 6 and 8 are connected to the transmission control unit 10 via signal transmission lines 13, as shown in FIG. In this embodiment, the transmission control unit 10 performs data transmission using a polling method.

Each of the main and sub remote controllers 4, 6, 8 has a time display 20, 2 on each display panel 14, 16, 18.
2, 24, reserved operation mode transition switch 26, 2
8, 30 and reserved operation display lamps 32, 34, 36 indicating that the switch has been operated are provided, respectively, and each display panel 14, 16, 18
Internally there are registers 38 and 4 that store the reservation time.
0.42. Furthermore, each remote control 4,
6 and 8 are respectively provided with a display time changeover switch 43 on the display panel 14 and a reservation time setting switch 44 as operation means for setting the driving reservation time, and only the main remote controller 4 has a built-in clock control section 46. .

In the above configuration, data of the current time measured by the clock control section 46 of the main remote controller 4 is sent to the transmission control section 10 of the main body via the signal transmission line 13, and the transmission control section 10 further receives the current time. The data is output to the time displays 20, 22, 24 of the main remote controller 4 and the sub remote controllers 6, 8 via the signal transmission line 13. As a result, each of the main and sub remote controllers 4,
Time indicators 20, 22, and 24 at 6 and 8 display the current time.

To set a reservation time from this state, first press the display time switch 43 on one of the remote controllers. is received together with the address signal of the remote controller that operated the switch, and the clock control unit 46 receives only the signal of the reserved time setting switch 44 from the remote controller of the same address for a certain period of time or until the ON data of the display time changeover switch 42 is received again. In addition, by transmitting the ON data of the display time changeover switch 43 described above, the clock control section 46 switches from the normal mode to the reserved time setting mode, as shown in FIG. After operating the reservation time setting switch 44 to set the reservation time, when the display changeover switch 43 is pressed again, the reservation time is confirmed and the normal mode is returned to, and at the same time, the main remote controller 4 controls the clock. The reservation time setting data is sent from the section 46 to the transmission control section 10 of the main body controller 2 via the signal transmission line 13.
Upon receiving this data, the transmission control unit 10 transfers the data to each remote controller 4, 6, and 8 via the transmission line 13 again. As a result, each register 38, 40 of the main remote controller 4 and the sub remote controllers 6, 8,
42 stores reservation time data.

Next, when the timer reservation operation mode transition switch 30 is pressed on the sub remote controller 8, for example, the ON data from the sub remote controller 8 is transmitted to the transmission control section 10 via the signal transmission line 13, so the transmission control section 10 transfers this data to the sequence control unit 9, while transmitting the data again via the signal transmission line 13 to the main remote controller 4 and the sub remote controller 6,
8. Therefore, each timer reserved operation display lamp 3 of the main remote controller 4 and the sub remote controllers 6 and 8
2, 34, and 36 light up, and based on the data, each time display 20, 22, 24 shows the following:
The reservation time stored in advance in the registers 38, 40, and 42 is displayed for a certain period of time (for example, 10 seconds).

Further, in any remote controller, for example, the sub remote controller 6, the timer reserved operation transition switch 2 is activated.
8 is turned off, the timer reservation operation mode changes to the normal mode, the off data is input to the transmission control section 10 of the main controller 2, the timer reservation operation state is canceled, and the off data is used for signal transmission. Main remote control 4 via line 13
and is transmitted to the sub remote controllers 6 and 8. Therefore, the timer reservation operation display lamps 32, 34, and 36 of each remote controller 4, 6, and 8 are turned off.

When the current time matches the timer reservation time, a coincidence signal is output from the main remote controller 4, and this coincidence signal is input to the sequence control section 9 via the signal transmission line 13 and the transmission control section 10. In response to this coincidence signal, the sequence control section 9 controls the combustion control section 12.
A combustion start signal is output to start the combustion operation of the bathtub.

Although two sub remote controllers are provided in this embodiment, it is needless to say that the number is not limited to this.

(Effects of the Invention) As described above, according to the present invention, the reserved time of the clock control unit provided in the main remote controller can be changed even on the sub-remote controller side, and excellent effects such as improved usability than in the past can be achieved.
