Urinal apparatus and urinal unit

A urinal apparatus comprising:

• a water supplying device configured to supply water to a bowl surface of a bowl section of a urinal, and to remove urine attached to the bowl surface of the urinal;
• a water sprinkling device including a sprinkling hole configured to sprinkle water to a space inside the bowl section;
• and
• a human body sensing device configured to sense use of the urinal, the human body sensing device performing urinal standing sensing and urinal surrounding sensing, the human body sensing device sensing presence or absence of a human body within a first sensing distance by the urinal standing sensing, the human body sensing device sensing presence or absence of a human body within a second sensing distance by the urinal surrounding sensing, the second sensing distance being longer than the first sensing distance,
• the water supplying device supplying the water when the human body sensing device has transitioned from a human body sensing state to a human body non-sensing state by the urinal standing sensing,
• the water sprinkling device being prohibited from sprinkling the water from the sprinkling hole while the human body sensing device, performing the urinal surrounding sensing, is in a human body sensing state, and
• an amount of water supplied to the bowl section in one operation by the water supplying device is larger than an amount of water sprinkled to the space in one operation by the water sprinkling device.
