BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic flushing urinal in which a functional unit such as a valve unit for automatic flushing or a sensor for detecting a user is integrally incorporated into a toilet body.

[0002]

2. Description of the Related Art A flush-type urinal is provided with a flush flush valve for flushing a ball by a manual flush valve, and a sensor for detecting a person is provided so that a certain amount of flush water is flushed after use. Automatic cleaning type is available.

[0003] The automatic flushing urinal has a unit in which a unit such as an electric flash valve is installed in a wall, its piping is connected to a toilet body, and an optical sensor for sensing a person is installed on the wall. Has been widely used in the past. In order to simplify construction and maintenance inspections, and to be able to meet the specifications for ordinary households, toilet units with valve units and sensors built into the toilet itself have already been developed. ing. Such a type is disclosed in Japanese Patent Application No. Hei 3-6278.
(See Japanese Utility Model Laid-Open No. 4-105182).

[0004] In this urinal of the automatic flushing type, a storage space for incorporating a valve unit and a sensor is newly provided at an upper end portion of a toilet body, and a functional part is hidden by covering a lid on the storage space. The functional units include a supply pipe for washing water such as an electromagnetic valve type on-off valve and a flush valve using a piston valve, a sensor for detecting a person, a controller for receiving a signal from the sensor and operating a valve unit, and A battery box or the like containing a battery for power supply is incorporated.

[0005]

The storage space for accommodating the functional unit provided at the upper end of the toilet has a rear surface for connecting the supply pipe for washing water piped in the wall and the internal flow path formed in the toilet body. It is necessary to make the shape open side. For this reason, since the urinal is installed with its back face against the wall, the storage space is closed on the back side by this wall.

[0006] On the other hand, the lid to be put on the storage space can be removed for maintenance and inspection of the functional unit and replacement of the battery. For this reason, if the lid is not properly covered, water may enter the storage space at the time of wiping and cleaning. In addition, when the toilet body and the lid are made of ceramic, the dimensional accuracy is not so high, so that if the joint surface has looseness, the degree of water entry is high.

[0007] As described above, if water enters the storage space, its back is closed by the wall, so that there is no place for water to escape. For this reason, the water remains in the storage space, and it has no choice but to wait for natural drying. As a result, rust is generated in the functional part including the electric parts, and an accident such as electric leakage is caused.

[0008] In addition to the intrusion of water from the outside, the same problem occurs due to dew condensation water generated in cold weather.

A problem to be solved in the present invention is that in a urinal having a functional unit for automatic cleaning integrated with a toilet body, water can be drained from a storage unit containing the functional unit to protect the functional unit. It is to plan.
