TECHNICAL FIELD OF THE INVENTION
The present invention relates to a flush water supply device for a toilet that controls the supply of flush water to a toilet, and in particular, normally performs a water supply operation using a main power supply such as a commercial power supply, and shuts off power supply from the main power supply in a power outage or the like. The present invention relates to a washing and water supply device in which a water supply operation is performed by a backup power supply when the power supply becomes.
[0002]
[Prior art]
For a long time, a flush valve for performing a flush operation for flushing flush water into a toilet bowl and draining filth in a toilet bowl to a drain pipe has been used, but in recent years, a warm water flushing device (human buttock) has been used. With the widespread use of a device for cleaning the same with hot water, an electric flash valve mechanism that can be operated by a remote controller has been increasingly used.
[0003]
Since the electric flash valve mechanism uses a commercial power supply as a main power supply, it does not operate during a power failure. Therefore, the valve device is often configured so that the valve can be manually opened. However, a user who is accustomed to the flash operation by operating the switch of the remote control may not know how to use the flash.
[0004]
JP-A-3-224919 discloses that a backup power supply is provided so that the electric flash valve mechanism can be operated even during a power failure.
[0005]
[Problems to be solved by the invention]
In recent years, the power situation has been significantly improved, and no power outage will occur unless a small accident occurs. Mounting a backup power supply for such a rare case only increases the cost of the toilet equipment. In addition, arranging a backup power supply that is rarely used in a casing such as a toilet seat box at the rear of the toilet also hinders downsizing of the toilet seat box.
[0006]
The present invention solves such a problem, and uses a battery of a remote controller to provide a flush water supply device that can flush toilet flush water by operating a switch of the remote controller even when power supply from the main power supply is cut off. It is intended to provide.
[0007]
[Means for Solving the Problems]
The flush water supply apparatus of the present invention is a toilet flush water supply apparatus provided with a backup power supply that supplies power when power supply from a main power supply is cut off, wherein the backup power supply is a remote control battery.

[0008]
According to the flush water supply device of the present invention, even during a power outage, the toilet can be flushed by operating the switch of the remote controller using the battery of the remote controller.
[0009]
In the present invention, it is not necessary to provide a dedicated backup power supply for a power failure in a toilet seat box or the like, so that the cost of the washing water supply device can be reduced, and the casing of the toilet seat box or the like can be reduced in size. It is also possible.
[0010]
In the present invention, it is preferable that a connection terminal for energization is provided in each of the main body unit installed on the toilet and the remote controller, and power is supplied to the main body unit from the remote controller via the connection terminals. In the case of such a configuration, for example, by removing the remote control from the wall surface and connecting the connection terminal of the remote control to the connection terminal of the main body, the cleaning water supply device can operate even during a power failure.
[0011]
In addition, a dry battery with a small capacity of about AA is often used as a battery of the remote controller. Therefore, when a control circuit for controlling the hot water cleaning device and the cleaning water supply device is provided, when the power supply from the main power supply is cut off, only the cleaning and water supply operation to the toilet bowl is performed by the power from the battery. Is preferred.
