Abstract

PURPOSE:To increase the degrees of freedom of the installing place of a bathroom interphone, and to control switching of channel in case of multi-channel interphones by conducting calling of a second place such as a kitchen or the like from a first place such as a bathroom or the like by a hot water supplying apparatus remote controller, and eliminating the operation by the bathroom interphone. CONSTITUTION:When a calling switch 81 provided in an interphone slave unit 8 is operated, a calling discriminator 91 is operated, a relay coil 92 is controlled, and a speech channel switching contact 93 is switched to the unit 8. When a calling switch 41 of a first hot water supplying apparatus remote controller 2 is operated, calling detecting means 5 is provided in a second hot water supplying apparatus remote controller 3, an external unit control signal is output to an external unit control output terminal 6, the discriminator 91, the coil 92 are operated, and the contact 93 is switched to an interphone slave unit 7. A speech signal selected by the contact 93 is connected to a transceiver 95 through a transceiver circuit 94, and a speech from the unit 7 or 8 can be conducted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote control device that remotely controls a water heater and external devices other than the water heater.

Conventional technology Large water heaters that can simultaneously supply hot water to baths, kitchens, etc. have become increasingly electronically controlled in recent years, making it possible to remotely control the amount and temperature of hot water at a location away from where the water heater itself is installed. Yes, this is becoming more and more common, but it only controls the water heater, and there has been no attempt to control external equipment other than the water heater.

Problems to be Solved by the Invention During bathing, it is often necessary to communicate from inside the bathroom to the outside, such as when a towel or soap is needed, or when a signal is given to pick up a child. For this reason, there has recently been an increase in the number of intercoms being installed in bathrooms and kitchens, but ink-pons installed in bathrooms have poor installation conditions as they can get wet with hot water, and for aesthetic reasons, it is recommended to install them on the ceiling. However, the problem arises that the call switch cannot be operated.

In order to solve the above problems, the present invention provides a remote control device that can call an intercom using the remote control of a water heater, and can also control line switching in the case of a multi-station intercom. purpose.

Means for Solving the Problems The present invention provides a main body of a water heater that supplies hot water to baths, kitchens, etc., and a first system located away from the installation location of the main body of the water heater to control the amount, temperature, etc. of the island sent from the main body of the water heater. A first water heater remote control that is remotely operated at a location, and a second water heater remote controller that is remotely operated in the same way as the first water heater remote controller at a second location separate from the first location. The first water heater remote control includes a call means for calling the second water heater remote control, and the second water heater remote control includes a call detection means for detecting a call from the first water heater remote control and a call. The configuration includes an external device control output terminal that controls external devices in conjunction with detection.

Function The present invention has the above-described configuration, and a water heater remote control is used to call from a first location such as a bathroom to a second location such as a kitchen, thereby eliminating the need for operations using a bathroom intercom. This makes it possible to increase the degree of freedom in the installation location of the intercom, and for multi-station intercoms where the intercom is installed in a third location such as the entrance, the line can be switched using the external device control output terminal. It also makes it possible to do both at the same time.

The embodiment diagram is a configuration diagram showing an embodiment of the present invention. 1 is the main body of the water heater, 2 is the first water heater remote control, and 3 is the second water heater remote control. When the operation switch 21 of the first water heater remote control 2 is operated, a remote control signal is transmitted from the remote control transmitter 22 and transmitted to the water heater main body 1 via the path A in the figure.
Control this. The same goes for the second water heater remote controller 3, and when the operation switch 31 is operated, the remote controller transmitter 3
A control signal from 2 to 1 is transmitted to the main body 1 of the water heater through the path A in the figure, and is then controlled.

A calling means 4 is provided in the first water heater remote controller 2, and when the calling switch 41 is operated, a calling signal is generated and sent to the second water heater remote controller 3 via the remote control transmitter 22 along the route shown in the middle of the figure. transmitted. A call detection means 5 is provided in the second water heater remote controller 3, and when a call signal is input, it sounds a buzzer 51 and at the same time outputs an external device control signal to the external device control output terminal 6.

Reference numeral 9 is an intercom base unit installed at the second location, 7 is an intercom slave unit installed at the first location, and 8 is an intercom slave unit installed at the third location. When the call switch 81 provided on the intercom handset 8 is operated, the call determination circuit 91 operates, controls the relay coil 92, and switches the call line switching contact 93 to the intercom handset 8.
Switch to the side. When the call switch 41 of the first hot water heater remote control 2 is operated, an external device control signal is outputted from the external device control output terminal 6 as described above, which activates the call determination circuit 91 and relay coil 92, and connects the call line switching contact. 93 to the intercom handset 7 side. The call signal selected by the call line switching contact 93 is connected to a handset 95 via a transmitter/receiver circuit 94, thereby making it possible to talk to the intercom handset 7 or 8.

Effects of the Invention As is clear from the above embodiments, the present invention allows a call from a first location to a second location to be made using the water heater remote control installed for the water heater. There is no need to install a call switch on the intercom to be installed, so the intercom in the first location can be installed in places that cannot be reached, such as on the ceiling, and you can freely choose a location with good installation conditions that does not require pumping of water. It has the excellent effect of being able to In addition, the second water heater remote control is equipped with an external device control output terminal, so if you have a multi-station intercom that also has an intercom at a third location, you can automatically switch the call line at the same time. It has this excellent effect.
