Abstract

A water discharging device (10) includes a raw water discharging part (14) and a reformed water discharging part (12). The raw water discharging part (14) is capable of discharging raw water supplied from a water supply source by switching a water discharging form between a spray form and a stream form. The reformed water discharging part (12) discharges reformed water obtained by reforming the raw water. The raw water discharging part (14) is disposed around the reformed water discharging part (12) so as to surround the reformed water discharging part (12).

First claim

1 . A water discharging device comprising:
a raw water discharging part capable of discharging raw water supplied from a water supply source by switching a water discharging form between a spray form and a stream form; and a reformed water discharging part that discharges reformed water obtained by reforming the raw water, wherein the raw water discharging part is disposed around the reformed water discharging part so as to surround the reformed water discharging part.

2 . The water discharging device of claim 1 , wherein
the raw water discharging part includes a spray water discharging part that discharges the raw water when the water discharging form is the spray form, and a stream water discharging part that discharges the raw water when the water discharging form is the stream form, and the stream water discharging part is disposed around the spray water discharging part so as to surround the spray water discharging part.

3 . The water discharging device of claim 2 , wherein
the spray water discharging part forms a water spraying surface in which a plurality of water spraying holes is formed, the water spraying surface is a surface exposed in a discharging direction of the raw water of the raw water discharging part, the water spraying surface being inclined forward in the discharging direction from an outer peripheral side toward a center, and the stream water discharging part is provided on an outer peripheral side of the spray water discharging part and forms a flow of the raw water going toward the center of the raw water discharging part along the water spraying surface.

4 . The water discharging device of claim 2 , further comprising an opening/closing part configured to open and/or close a stream flow path communicating with the stream water discharging part, wherein
in a state where the opening/closing part closes the stream flow path, the raw water discharging part discharges the raw water only from the spray water discharging part, thereby forming spray water discharge, and in a state where the opening/closing part opens the stream flow path, the raw water discharging part forms stream water discharge consisting of the raw water discharged from the stream water discharging part and the raw water discharged from the spray water discharging part joined together.

5 . The water discharging device of claim 4 , further comprising:
a water spraying member in which a plurality of water spraying holes are formed and that constitutes the spray water discharging part; and a pipe member having a tubular shape provided to extend through the water spraying member, the pipe member including the reformed water discharging part provided at a distal end of the pipe member, wherein the water spraying member is provided to move freely along an axial direction of the pipe member, the stream water discharging part is a first stream water discharging part provided on an outer peripheral side of the water spraying member, the raw water discharging part includes a second stream water discharging part formed between the water spraying member and the pipe member, the second stream water discharging part discharging the raw water when the water discharging form is the stream form, and the opening/closing part is a first opening/closing part that is configured to open and/or close a first stream flow path serving as the stream flow path, the water discharging device comprises a second opening/closing part that is configured to open and/or close a second stream flow path communicating with the second stream water discharging part, and the first opening/closing part and the second opening/closing part open the first stream flow path and the second stream flow path, respectively, when the water spraying member moves to a downstream side in the axial direction and close the first stream flow path and the second stream flow path, respectively, when the water spraying member moves to an upstream side in the axial direction.

6 . The water discharging device of claim 5 , wherein
the second opening/closing part closes the second stream flow path before the first opening/closing part closes the first stream flow path.

7 . The water discharging device of claim 5 , wherein
the pipe member moves freely along the axial direction, an elastic force toward the downstream side in the axial direction being applied to the pipe member, and the second opening/closing part closes the second stream flow path when the water spraying member moves to the upstream side in the axial direction so as to push back the pipe member to the upstream side in the axial direction against the elastic force.

8 . The water discharging device of claim 4 , further comprising a guide part that guides the raw water to the stream flow path.
