DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention relates to a toilet bowl,
The present invention relates to a main body case structure of a sanitary washing device capable of jetting hot water stored in a hot water tank from a washing nozzle.

[0002]

2. Description of the Related Art Conventionally, as this type of sanitary washing device,
For example, the one shown in FIG. 8 is known. The sanitary washing device 1 fixes the bottom surface side of the main body case 3 provided with the toilet seat 5 and the washing nozzle 2 to the rear of the toilet seat with a mounting plate and bolts (not shown). The main body case forms the exterior of the device, and houses related devices inside.

[0003] On one side of the main body case 3, a hot water tank accommodating portion 4 for accommodating therein a hot water tank for storing hot water for cleaning is integrally formed so as to protrude. A water supply unit composed of a valve unit is provided on the back side of the hot water tank, and a water supply port 6 extending to the outside is provided. A portion 4A for accommodating the water supply port 6 protrudes rearward from the hot water tank housing 4. It was integrally molded.

For maintenance and inspection of the water stop solenoid valve constituting the valve unit, the upper cover 3A of the main body case 3 is removed, and the whole hot water tank is taken out of the hot water tank housing 4.

[0005]

However, in such a conventional sanitary washing device, the valve unit is attached to the hot water tank when performing maintenance or inspection such as removing the clogging of the water stop solenoid valve of the valve unit. The hot water tank is fixed in the hot water tank housing 4 with screws and the related devices are further attached, and the valve unit is also connected to the peripheral device.
