Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an intercom system capable of mutual communication with a remote controller on the side of a hot water supply device.
[0002]
[Prior art]
The conventional intercom system is generally not connected to the control system of the hot water supply device, and is independent from the control system of the hot water supply device. On the other hand, when a visitor operates the entrance cordless handset while cooking in the kitchen, the remote controller of the hot water supply device has a function as a handset for the interphone so that it can respond without moving to the indoor handset location of the interphone. What was added is known (for example, refer patent document 1).
[0003]
[Patent Document 1]
JP 2000-292001 A (FIG. 1)
[0004]
[Problems to be solved by the invention]
In the above-mentioned Patent Document 1, for example, if the bathtub is forgotten to be closed when automatic hot water filling is performed by a hot water supply device, the water level does not rise even after a certain period of time. It is judged that it has occurred, and that fact is notified from the kitchen remote control. However, if the housekeeper moves to a room other than the kitchen, the housekeeper cannot know the occurrence of this error.
[0005]
Note that the interphone described in Patent Document 1 is an interphone system that includes only two slave units, that is, an entrance slave unit and an indoor slave unit. An intercom system in which an indoor cordless handset and a plurality of indoor cordless handsets are connected to an interphone master phone is known.
[0006]
However, what is described in the above-mentioned Patent Document 1 is the one in which the function of the indoor child device is simply added to the kitchen remote controller, and only the entrance child device is connected to the indoor child device. Even if information such as the occurrence of an error in the control system is transmitted to the interphone system, the information such as the occurrence of an error will be notified from the entrance unit, and such a configuration cannot actually be adopted. .
[0007]
Then, this invention makes it a subject to provide the bath remote control which does not produce the above malfunctions in view of said problem.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, an intercom system according to the present invention includes a bathroom remote unit capable of communicating with an interphone base unit installed outside the bathroom, and a bath remote controller and a bathroom having a function of monitoring the operation status of the hot water supply device. In the intercom system that can communicate with the slave unit, when an error occurs on the hot water supply side, an error signal is sent to the bathroom slave unit, and at least the occurrence of the error is reported by the interphone master unit. It is characterized by that.
[0009]
According to the above configuration, when an error occurs on the hot water supply device side, in addition to each remote controller connected to the hot water supply device, at least the occurrence of the error is notified by the intercom master unit, and the householder moves from the installation location of the remote control. Even if this is the case, the opportunity to know the occurrence of the error increases.
[0010]
In addition, the interphone master unit can communicate with an external monitoring device via a communication line, and if the error occurrence is transmitted to the monitoring device, the monitoring device detects the occurrence of the error. From this monitoring device, it is possible to issue a prompt and appropriate instruction to a maintenance company or the like.
[0011]
In addition, if the monitoring device relays when diagnosing the operating condition of the hot water supply device, the occurrence of an error can be detected in advance and appropriate processing can be performed before the error occurs.
[0012]
