〔effect〕
As described above, the toilet hand-washing device system of the present embodiment includes the toilet bowl 1 and the hand-washing machine 6. The toilet bowl 1 has a power supply unit 5 built in the toilet bowl main body 2 and an electric device 3 that operates by receiving electric power from the power supply unit 5. The hand-washing device 6 is provided with a faucet 62 connected to a water supply channel (hand-washing side water supply channel 69) and an electric drive valve provided in the water supply channel (hand-washing side water supply channel 69) that can switch between water stoppage and water flow. It has 63 and. The electric drive valve 63 is configured to operate by receiving electric power from the power supply unit 5 built in the toilet bowl main body 2.

According to this configuration, the power supply unit 5 required for the electric drive valve 63 of the hand-washing device 6 can be shared with the power supply unit 5 of the toilet bowl 1, and conventionally, it is required for each of the hand-washing device 6 and the toilet bowl 1. The number of power supply units 5 that was used can be reduced. As a result, the number of parts can be reduced and the cost can be reduced.

Moreover, since power can be supplied to the hand-washing device 6 by using the power supply unit 5 built in the toilet bowl main body 2, it is possible to additionally install the hand-washing device 6 in addition to the existing toilet bowl 1. Is.

In addition, in the conventional hand-washing device 6, it is necessary to newly install a power outlet in the toilet room in order to obtain the electric power of the commercial power source, and a separate electrical work is required to install the hand-washing device 6. However, according to the toilet hand-washing system of the present embodiment, this work man-hour can also be reduced. As a result, the toilet bowl 1 and the hand-washing bowl 6 can be installed without any work by an electrician.

In addition, the toilet hand-washing system of the present embodiment includes the following additional configurations. That is, in the toilet hand-washing device system of the present embodiment, the hand-washing machine 6 has a valve control device 64 that controls the electric drive valve 63. The valve control device 64 is configured to receive electric power from the power supply unit 5 of the toilet bowl 1.

According to this configuration, even if either one of the control unit 4 installed in the toilet bowl 1 and the valve control device 64 installed in the hand-washing device 6 fails, the other can be prevented from being affected.

[Modification example]
In the above embodiment, the hand-washing device 6 includes a valve control device 64 that controls the electrically driven valve 63, but the hand-washing device 6 may have an embodiment as shown in FIG.

In the modified toilet hand-washing system, the control unit 4 of the toilet bowl 1 includes a toilet bowl control unit 41 and a hand-washing device control unit 42. Since the toilet control unit 41 has the same function as the control unit 4 of the first embodiment, the description thereof will be omitted.

The hand-washing device control unit 42 is electrically connected to the electric drive valve 63 of the hand-washing device 6 and controls the electric drive valve 63 of the hand-washing device 6. The hand-washing device 6 of this modification does not have the valve control device 64 in the above embodiment.

As described above, in the toilet hand-washing device system of this modified example, the toilet bowl 1 includes a control unit 4 for controlling the electric device 3. The control unit 4 has a hand-washing device control unit 42 that controls the electric drive valve 63 of the hand-washing device 6.

According to this configuration, the control unit 4 that controls the electric device 3 can include the control unit 42 for the hand washer that controls the electric drive valve 63, so that the parts constituting the control unit 4 can be standardized. And the number of parts can be reduced. Further, since the number of parts of the hand-washing device 6 can be reduced, it is possible to reduce the size of the hand-washing device 6.
