Abstract

To provide a urinal apparatus, including: a water supplying device configured to supply water to a bowl section of a urinal; a trap section provided in a lower part of the bowl section and configured so that urine and water flow into the trap section; and a water sprinkling device configured to sprinkle water droplets to a region inside the bowl section, the region being located between the trap section and position of a nose of a user facing the bowl section, wherein the timing of sprinkling the water droplets by the water sprinkling device being different from timing of supplying water by the water supplying device.

First claim

What is claimed is:

1. A urinal apparatus comprising:
a water supplying device configured to supply water to a back surface of a bowl section of a urinal for removing urine attached to the back surface of the bowl section of the urinal including a portion of the back surface in an upper part of the bowl section of the urinal configured to face a user; and
a water sprinkling device configured to sprinkle water droplets downward from the upper part of the bowl section through a space between the upper part of the bowl section and a lower part of the bowl section, each of the water droplets having a diameter of 10 micrometers or more and 1200 micrometers or less,
wherein the bowl section includes a front surface in the lower part of the bowl section and the back surface, the back surface including a portion in the lower part of the bowl section and the portion in the upper part of the bowl section, the front surface opposing the portion of the back surface in the lower part of the bowl section and the lower part including a region of the bowl section that includes an imaginary plane intersecting a lip section and the back surface.

2. The apparatus according to claim 1 , wherein
the water sprinkling device includes a sprinkling section provided in the upper part,
the water sprinkled by the sprinkling section is shaped like a cone or a sector, and
the water sprinkled by the sprinkling section ranges inside the bowl section.

3. The apparatus according to claim 2 , wherein the cone or the sector has an axis directed behind the urinal.

4. The apparatus according to claim 1 , wherein the water sprinkled by the water sprinkling device is functional water capable of decomposing ammonia.

5. A urinal apparatus comprising:
a first water supplying device configured to supply water to a back surface of a bowl section of a urinal for removing urine attached to the back surface of the bowl section of the urinal including a portion of the back surface in an upper part of the bowl section of the urinal configured to face a user; and
a second water supplying device configured to sprinkle water in a smaller amount than the water supplied by the first water supplying device, the second water supplying device sprinkling the water through a space above a lower part of the bowl section and to at least part of a first region of the bowl section not flushed with the water supplied by the first water supplying device,
wherein the bowl section includes a front surface in the lower part of the bowl section and the back surface, the back surface including a portion in the lower part of the bowl section and a portion above the lower part of the bowl section, the portion of the back surface in the lower part of the bowl section opposing the front surface and the lower part including a second region of the bowl section that includes an imaginary plane intersecting a lip section and the back surface.

6. The apparatus according to claim 5 , wherein
the first region includes a lateral side of a spreader.

7. The apparatus according to claim 5 , wherein the first region includes a tip part of the lip section of the urinal.

8. The apparatus according to claim 5 , wherein the water supplied from the second water supplying device and moving on one surface of the bowl section has a slower speed than the water supplied from the first water supplying device and moving on another surface of the bowl section.

9. The apparatus according to claim 5 , wherein the second water supplying device supplies water droplets to the bowl section.
