Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system for equipment remotely controlled by a remote controller, and more particularly to a remote communication system for hot water heat sources such as water heaters, bath heaters and heaters.

[0002]

2. Description of the Related Art Conventionally, equipment bodies such as hot water heat sources are
It is installed indoors or outdoors. A remote control device connected to the device body by wire or wirelessly is installed in the room to remotely control the device body. When there are a plurality of remote control devices such as a bathroom and a kitchen, they are connected to the main body of the device by wire or wirelessly.

[0003]

However, a plurality of remote control devices may be required in the same room such as a bathroom. For example, there are a remote operation device for setting the hot water refilling and reheating temperature for the bathtub, the amount of the hot water filling water, or the water level, and a remote operation device for setting the temperature and the water amount of the hot water tap or shower hot water. Of these, those mentioned above are conveniently placed near the bathtub, and those mentioned below are conveniently placed near the hot water tap or shower. Therefore, the location is limited and inconvenient to install a single remote control device having both functions.

On the other hand, in order to install them independently, if they are wired, they must be connected by wire to the main body of the equipment.
The workability was not good. In the case of a wireless remote control device, the same wireless output is required, which increases the cost burden.

An object of the present invention is to solve the above-mentioned conventional problems and to provide an inexpensive remote control system capable of remote control from a plurality of locations by a single wireless connection with a device body.

[0006]

In order to achieve the above-mentioned object, a remote communication system of the present invention comprises a main remote operation device for remotely operating a device main body by wireless communication, and a main remote operation device for wireless communication. A sub-remote control device having a transmission / reception circuit for transmitting and receiving and remotely controlling the device main body through the main remote control device is provided.

[0007]

Operation: The sub remote operation device having a transmitting / receiving circuit for transmitting / receiving to / from the main remote operation device by wireless communication sends the control information of the device main body to the main remote operation device, and the main remote operation device sends a wireless signal to the device main body Control the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A telecommunications system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a bathroom, which is provided with a bathtub 2 and a hot water tap 3. Reference numeral 4 is a wall, and a device body 5 of a bath kettle with a water heater is installed outdoors. The device body 5 and the bathtub 2 are connected by a reheating pipe 6, and the device body 5
The hot water supply tap 3 and the hot water supply tap 3 are connected by a hot water supply pipe 7. 8 is wall 4
The main remote control device is detachably attached to the wireless communication unit 9 of the device body 5 by radio (radio waves). The main remote control device 8 is provided with a switch 8a so that various kinds of settings (temperature, water amount, water level, etc.) can be set. A sub-remote control device 12 is detachably installed near the bathtub 2. This sub remote control device 1
2 is also provided with a switch 12a for setting various types (temperature,
Water volume, water level, etc.) can be controlled. The main remote control device 8 and the sub remote control device 12 are respectively provided with a wireless communication circuit 11 and a wireless communication circuit 13 for transmitting and receiving signals wirelessly (such as infrared rays).

FIG. 2 shows the relationship between the communication circuits. Figure 2
In the figure, 8 is a main remote control device, and a wireless communication circuit 11 for exchanging signals with a wireless communication unit 9 and a sub remote control device 12 mounted on the main body of the device, and a main remote control device 8
And a wireless communication I / I for exchanging signals between the sub remote operation device 12 or the main remote operation device 8 and the wireless communication unit 9.
It is composed of an F circuit 17. Reference numeral 12 denotes a sub-remote control device, a wireless communication circuit 13 for transmitting and receiving signals to and from the main remote control device 8, and wireless communication I for decoding signals from the main remote control device 8.
The / F circuit 18 is used. The wireless communication unit 9 includes a wireless communication circuit 14 that sends and receives signals to and from the main remote controller 8, and a wired communication I / F circuit 15 that sends a signal to the device body 5 and receives device information. . Reference numeral 10 is a control device mounted on the device body 5 for controlling the device, and a wireless communication unit 9
It is composed of a wired communication I / F circuit 15a for exchanging signals with and.

Next, the operation of the above configuration will be described. When using hot water in the shower or washroom, the main remote control device 8
To set the hot water temperature and hot water amount. The signal is transmitted by radio waves to the wireless communication circuit 14 of the wireless communication unit 9 by the wireless communication circuit 11 of the main remote controller 8. The transmitted signal is sent to the wired communication I / F circuit 15a of the control device 10 via the wired communication I / F circuit 15 of the wireless communication unit 9, and the device control circuit 16 controls the device body. The state of the device body 5 is the wired communication I / F circuit 15a of the control device 10 and the wired communication I / F circuit 1 of the wireless communication unit 9.
5, sent to the wireless communication circuit 11 of the main remote controller 8 via the wireless communication circuit 14 for display, and to the wireless communication circuit 13 of the sub remote controller 12 via the wireless communication circuit 17 of the main remote controller 8. Sent to display the control status of the device.

Next, the case of automatically filling and reheating the bathtub 2 will be described. The set value set by the sub remote operation device 12 and the operation signal of the switch 12a are transmitted to the wireless communication circuit 13 via the wireless communication I / F circuit 18. The transmitted signal is the infrared remote control device 8
To the wireless communication circuit 14 of the wireless communication unit 9 by radio waves. Then, the equipment main body 5 is controlled according to the flow described above, and the state of the equipment is returned to the sub remote control device 12 according to the flow described above. Further, since the main remote operation device 8 and the sub remote operation device 12 are detachable, they can be installed anywhere and various operations can be conveniently performed. Further, the main remote control device 8 and the sub remote control device 1
2 is a wireless communication method other than radio waves such as infrared rays, so that a simple and inexpensive communication system can be made.

[0013]

As is apparent from the above description, according to the remote communication system of the present invention, there is no need for the wiring work between the main body of the equipment and the remote control device, and where the main remote control device and the sub remote control device are located. However, since it can be installed, the workability is improved compared to the past. Further, since the main remote control device and the sub remote control device perform wireless communication by means other than radio waves such as infrared rays, a simple and inexpensive communication system can be made, and usability is improved.
