Description

The present invention prevents urine droplets from scattering and contaminating the toilet bowl and its surroundings when a man urinates in a standing posture using a Japanese-style or Western-style toilet bowl. It relates to a urinal for guiding to a toilet bowl.

Urinals are usually designed for men only and are designed so that they can urinate in a standing position without sitting down. There are Japanese-style squatting toilets and Western-style sitting toilets. In homes and public facilities that are not equipped with urinals, the urinals are often shared for defecation and urine, and men normally urinate while standing on such shared urinals. When a person urinates while standing on the toilet bowl, the droplets contaminate the toilet bowl and its surroundings, which is unsanitary and causes a foul odor. In addition, in recent years, there is concern about infectious diseases caused by viruses, and there is a demand for a simple urinal that can be used as a urinal and has a simple anti-scattering function.

Conventionally, various simple urinals have been proposed to prevent droplets from scattering when urinating in a standing urinal, but problems such as residual odors and deposits in the urinal and the complexity of handling remain unresolved. It remains as it is and has not yet spread.

Japanese Patent Application Laid-Open No. 2007-303064 proposes a mechanism for receiving urine with a funnel-shaped urine receiver and guiding it to a toilet bowl, and a method for supplying water from a water supply tank to the urine receiver after urination to wash the urine receiver. It is This method replenished water from the wash basin of the water supply tank, so the water pressure and flow rate were low, and the detergency was low. In addition, since the water in the water supply tank is replenished, sufficient cleaning water cannot be stored in the water supply tank.

Japanese Patent Application No. 2014-169613 proposes a detachable urinal including a urination tube and a storage stand. This method is inconvenient because it does not have a washing device, and it is necessary to pour water with a jug or spray a deodorant every time after urinating. In addition, since it was not possible to continuously wash during urination, urine components precipitated over time, giving off an unpleasant odor.
