Abstract

According to one embodiment, a sanitary washing device includes a main part, a toilet lid, and a radio wave sensor. The main part includes a toilet lid opening/closing part including a metal. The toilet lid is pivotally supported by the toilet lid opening/closing part to be rotatable with respect to the main part. The radio wave sensor is provided in an interior of the main part and uses a radio wave to detect a user in front of the main part. The radio wave sensor is positioned further frontward than the toilet lid opening/closing part. At least a part of the radio wave sensor overlaps at least a part of the toilet lid opening/closing part in a horizontal direction.

First claim

What is claimed is:

1 . A sanitary washing device, comprising:
a main part including a toilet lid opening/closing part including a metal; a toilet lid pivotally supported by the toilet lid opening/closing part to be rotatable with respect to the main part; and a radio wave sensor provided in an interior of the main part, the radio wave sensor using a radio wave to detect a user in front of the main part, the radio wave sensor being positioned further frontward than the toilet lid opening/closing part, at least a part of the radio wave sensor overlapping at least a part of the toilet lid opening/closing part in a horizontal direction.

2 . The device according to claim 1 , further comprising a toilet seat,
the main part further including a toilet seat opening/closing part including a metal, the toilet seat being pivotally supported by the toilet seat opening/closing part to be rotatable with respect to the main part, the toilet seat opening/closing part being positioned further frontward than the toilet lid opening/closing part, an upper end of the toilet seat opening/closing part being positioned lower than an upper end of the toilet lid opening/closing part.

3 . The device according to claim 1 , wherein at least a part of the radio wave sensor does not overlap the toilet lid opening/closing part in a frontward/rearward direction when viewed from above.

4 . The device according to claim 2 , wherein a distance between the radio wave sensor and the toilet seat opening/closing part is shorter than a distance between the radio wave sensor and the toilet lid opening/closing part.
