[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet provided with a functional part for, for example, local cleaning, and more particularly to a structure for connecting a ground wire of a controller of the functional part to an external ground wire.

[0002]

2. Description of the Related Art A sanitary washing apparatus for local washing, in which a casing is fixed to a toilet body, has been conventionally used. This sanitary washing device is provided with a nozzle device for local washing in a casing, and a hot water tank and a valve unit for supplying washing water to the nozzle device are provided. It incorporates equipment. A controller for controlling the operation of these devices and adjusting the temperature and flow rate of the washing water and the hot air is also housed in the casing.

[0003] Since such a sanitary washing apparatus uses water and is provided in a flush-type toilet, it must be grounded to prevent electric leakage and electric shock. For this reason, it is common practice to connect a ground wire to the controller and connect it to an external water supply pipe provided in a building, for example.

[0004] Since the sanitary washing device is attached to the toilet body, there are many independent products as products. And
For installation work on site, the terminal part of the ground wire connected to the controller is fixed so as to face the outside of the casing, and an external ground wire is connected to this terminal.

[0005]

In the case where such a ground wire is provided, since the sanitary washing device is a plumbing device, the lead wire of the ground wire that is exposed at the connection terminal portion should not be covered with water. Need to be done. For this reason, in the related art, for example, a structure has been adopted in which a connection fitting for a terminal is fixed to a casing so as to stand up and a lead wire is connected to an upper end thereof. With such a raised fitting, even if the covering of the ground wire gets wet due to condensation, etc., it can be dropped by draining water,
The lead wire is prevented from being wet.

However, since the shape of the connection fitting is considerably complicated, not only is the processing complicated, but also the workability in assembling the casing is greatly affected. In the conventional connection fitting, the ground wire from the controller and the ground wire to the outside are fixed with screws, and the connection fitting itself is fixed to the casing with another screw. For this reason, there is a limit in reducing the number of assembly steps and the number of parts.

The problem to be solved in the present invention is that the connection fitting can be easily fixed to the casing without requiring the connection fitting to have a complicated shape, and the lead wire is reliably prevented from being wet by the lead wire.

[0008]

According to the present invention, a casing containing an electrically controlled functional unit is fixed to a toilet body,
A toilet provided with a controller for controlling the functional unit in the casing, wherein a grounding wire of the controller is connected to an external grounding wire by a fitting provided on an outer peripheral portion of the casing, wherein the fitting is a base; The fixed seat has an inverted L-shaped vertical cross section that rests on a fixed seat formed on an edge and abuts against an outer peripheral surface. The fixed seat includes a holding wall that wraps around a peripheral surface of a portion where the connection fitting rests on the fixed seat, and the holding wall. A drain groove formed by being depressed outside the wall, wherein a screw connected to the ground wire is passed through the connection fitting and fixed to the fixing seat.

[0009]

The connection fitting having an inverted L-shaped vertical cross section is fixed by placing the horizontal portion on a fixed seat and inserting a screw connected to a ground wire passing through the fixed seat into the fixed seat. For this reason, the screw for connecting the ground wire to the connection fitting is used not only for connection with the external ground wire, but also for attaching the connection fitting to the fixed seat. Also,
If the end of the coating of the ground wire is positioned on the drain groove provided recessed around the holding wall of the fixed seat, water droplets traveling down this coating are dropped on the drain groove. For this reason, the lead wire on the connection fitting side is prevented from getting wet by water droplets.
