Abstract

There is provided a bathtub, including: a bottom surface part; a side surface part surrounding the bottom surface part, extending upward from the bottom surface part, and including a backrest part; a pillow part provided to be movable vertically over a prescribed range along the backrest part; and a water discharger mounted to the pillow part, the water discharger being provided to be movable vertically along the backrest part with the pillow part.

First claim

The invention claimed is:

1. A bathtub, comprising:
a bottom surface part;
a side surface part surrounding the bottom surface part, extending upward from the bottom surface part, and including a backrest part inclined downward and toward a front of the bathtub;
an axial part extending in the vertical direction along the backrest part;
a supporter supporting the axial part to be movable, the supporter being provided at the backrest part;
a pillow part being mounted to the axial part, the pillow part provided to be movable vertically over a prescribed range along the backrest part; and
a water discharger mounted to the pillow part, the water discharger being provided to be movable vertically along the backrest part with the pillow part, and
the pillow part being moved with the axial part over the prescribed range along the backrest part in the state of covering the supporter, the axial part, and the water discharger.

2. The bathtub according to claim 1 , comprising:
a water supplier provided in the backrest part; and
a water supply functional part supplying, to the water discharger, hot water supplied from the water supplier,
the water supply functional part being capable of supplying the hot water supplied from the water supplier even when the water discharger is moving vertically along the backrest part with the pillow part.

3. The bathtub according to claim 1 , comprising:
a water supplier provided in the backrest part; and
a supply pipe connecting the water discharger and the water supplier and supplying, to the water discharger, hot water supplied from the water supplier,
the supply pipe having flexibility in which a shape of the supply pipe changes according to movement of the water discharger.

4. The bathtub according to claim 3 , wherein the pillow part covers the supply pipe so that a load from a front does not act on the supply pipe when the pillow part is at any height within the prescribed range.

5. The bathtub according to claim 3 or 4 , wherein
the water discharger has a laterally-long configuration extending in a left/right direction, and includes a connector to the supply pipe at least at one end in the left/right direction, and
the connector extends in the left/right direction from the one end.

6. The bathtub according to claim 5 , wherein
the water discharger has a water discharge port extending in the left/right direction and performing a broad water discharge, and
the connector is provided at two ends in the left/right direction.

7. The bathtub according to claim 6 , wherein
the water discharger further includes:
an internal flow channel feeding, to the water discharge port, hot water supplied from a pair of the connectors provided at two ends of the internal flow channel; and
a pair of decelerators provided in the internal flow channel to correspond respectively to the pair of connectors, the pair of decelerators decelerating a force of the hot water flowing into the internal flow channel from the pair of connectors.
