Toilet seat apparatus
According to one embodiment, a toilet seat apparatus that includes a main part mounted at a rear upper part of a toilet, a toilet seat provided rotatably with respect to the main part, and a radio wave sensor being provided in the interior of the main part and using a radio wave to sense a human body; and in the state in which the toilet seat is lowered, the toilet seat covers the radio wave sensor, and the radio wave passes through the toilet seat and is radiated frontward of the radio wave sensor.
1. A toilet seat apparatus, comprising:
a main part mounted at a rear upper part of a toilet;
a toilet seat provided rotatably with respect to the main part, a rear end part of the toilet seat being positioned at a rear part of the main part; and
a radio wave sensor being provided in an interior of the main part and using a radio wave to sense a human body, the rear end part of the toilet seat being positioned rearward of the radio wave sensor,
in a state in which the toilet seat is lowered, the toilet seat covering the radio wave sensor in a vertical direction, and the radio wave passing through the toilet seat and being radiated frontward of the radio wave sensor.
2. The apparatus according to claim 1 , wherein a thickness of a portion of the toilet seat where the radio wave passes through in the state in which the toilet seat is lowered is uniform.
3. The apparatus according to claim 1 , wherein at least a portion of the radio wave sensor is positioned higher than a rear end part of an opening of the toilet seat in the state in which the toilet seat is lowered.
4. The apparatus according to claim 1 , further comprising a heating unit provided in the toilet seat interior and including a metal,
at least a portion of the radio wave sensor being positioned higher than the heating unit in the state in which the toilet seat is lowered.
5. The apparatus according to claim 1 , further comprising a toilet seat rotation part supporting the toilet seat pivotally with respect to the main part,
the toilet seat rotation part being provided rearward of the radio wave sensor.
6. The apparatus according to claim 5 , further comprising a first toilet seat reinforcing part being provided in the interior of the toilet seat above the main part, being positioned frontward of the radio wave sensor, and supporting an upper plate of the toilet seat from below when the upper plate is deformed downward.
7. The apparatus according to claim 6 , further comprising a second toilet seat reinforcing part being provided in the interior of the toilet seat above the main part, being positioned above and rearward of the radio wave sensor, and contacting the upper plate of the toilet seat.
8. The apparatus according to claim 7 , wherein the radio wave sensor radiates the radio wave frontward through a region between the first toilet seat reinforcing part and the second toilet seat reinforcing part.
9. The apparatus according to claim 5 , further comprising:
a toilet lid;
a toilet lid rotation part supporting the toilet lid pivotally with respect to the main part; and
a toilet lid reinforcing part linked to the toilet lid rotation part and the toilet lid,
the toilet lid rotation part being provided rearward of the radio wave sensor,
the toilet lid reinforcing part being provided from the toilet lid rotation part to a region above the radio wave sensor.
10. The apparatus according to claim 1 , further comprising a toilet lid including a light source unit,
at least a portion of the radio wave sensor being positioned higher than the light source unit in a state in which the toilet lid is closed.
