Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply chamber structure of a flush urinal made of ceramics.

[0002]

2. Description of the Related Art Conventionally, as one form of a water supply chamber structure of a flush urinal, there has been one disclosed in Japanese Utility Model Laid-Open No. 56-130083.

That is, as shown in FIG. 5, the flush water supply chamber X is provided at the upper part of the urinal body Y, and is divided by a partition wall 53 into a first water supply chamber 51 and a second water supply chamber. It consists of 52 and.

Further, a water supply port 55 is provided on the upper surface 54 of the urinal body Y.
A plurality of water spray holes 57 are provided in the lower wall portion of the second water supply chamber 52 along the shape of the ball wall surface 56 so as to wash the ball wall surface 56.

Numeral 58 designates the wash water from the first water supply chamber 51 to the second water supply chamber
The cleaning water supplied from the water supply port 55 is supplied to the second water supply chamber 52 through the communication hole 58, and flows out from the plurality of water spray ports 57 along the ball wall surface 56. The ball wall surface 56 can be washed.

Further, a part of the wash water supplied to the first water supply chamber 51 is supplied to a rim water passage 59 which communicates with a rim water guide hole (not shown) formed at the tip of the first water supply chamber 51. The ball portion 60 is supplied and is configured to clean the ball portion 60 formed in the lower portion of the urinal body Y.

Thus, the first water supply chamber 51 and the second water supply chamber 52
By partitioning and, it is possible to appropriately distribute the amount of wash water flowing out from the water spray hole 57 and the amount of wash water flowing out to the ball portion under the urinal through the rim water passage 59. The cleaning water is made to uniformly flow out from the plurality of water spray holes 57.

When the water supply chamber X having the above structure is formed, the first water supply chamber 51 is usually cast integrally with the urinal body Y, but the second water supply chamber 52 is a lower wall portion. The wall constituent member 61 is separately formed, and the lower wall constituent member 61 is manually joined to the partition wall 53 and the ball wall surface 56, which form the lower surface of the first water supply chamber 51, by using an adhesive slurry. There is.

[0009]

However, in the water supply chamber structure described above, there is a problem that the molding cost becomes high because the lower wall constituting member 61 has to be formed separately.

Further, the operation of joining the lower wall constituent member 61 to the urinal body Y requires skill, and after the joining, the sticking-out sludge sticking out of the joining portion is removed or the sticking-out sludge is used. When the water spray hole 57 is blocked, it is necessary to perform a manual work such as opening the water spray hole 57 using a jig, resulting in poor molding work efficiency.

Further, since the lower wall constituting member 61 is joined in the state of the green body which is easily deformed after molding, the washing water is not deformed at the time of joining so that the washing water does not flow out uniformly from the respective water spray holes 57, and the ball wall surface.
There were 56 cleaning failures.

Further, water spray holes are provided in the portions near both ends of the rim.
57 could not be formed and the cleaning of both ends was insufficient.

Further, unless the water content of the urinal body Y and the water content of the lower wall constituting member 61 are made substantially the same at the time of bonding, the joining portion is not formed in the drying step and the firing step which are the next steps after molding. Cracks are likely to occur and product quality cannot be stabilized. Moreover, it takes a lot of time to manage the water content.

It is an object of the present invention to provide a water supply chamber structure of a flush urinal which can solve the above problems.

[0015]

According to the present invention, there is provided a flush water supply chamber which is located at an upper portion of a urinal body and which forms a space having a water supply opening on an upper surface thereof, and a rim which is opened on a wall surface of the water supply chamber. A water spray hole for cleaning the ball wall surface provided at the boundary between the water guide hole and the ball wall surface formed by extending the rear wall of the water supply chamber downward, and the water supply port and the water spray hole inside the cleaning water water supply chamber. The present invention relates to the structure of a water supply chamber of a flush urinal, which comprises a urinal body and a projecting portion which is integrally molded with the urinal body so as to project forward between the urinal and the urinal.

The present invention is also characterized in that the above-mentioned protrusion is made to protrude from the ball wall surface of the urinal body.
