As shown in FIGS. 2 and 3, the water discharging pipe 10 extends from the proximal end, which is the lower end, to the distal end, which is the upper end, of the water discharging device 1 in the installed state, along the linear central axis C. It is formed to extend in a straight line. The water discharge pipes 10 have substantially the same width in a direction perpendicular to the central axis C (hereinafter referred to as the vertical direction) when viewed from the side. Specifically, the vertical width of the water discharge pipe 10 is slightly larger on the distal end side than on the proximal end side. The left-right width of the water discharge pipe 10, that is, the width in the direction perpendicular to the central axis C direction and the longitudinal direction, tapers from the proximal end to the distal end, as shown in FIGS. 4 and 5. It has become.

A proximal end surface 10A, which is an end surface on the proximal side of the water discharge pipe 10, is formed as a surface inclined at a predetermined angle (approximately 45 degrees in the case of this embodiment) with respect to the central axis C. The base end surface 10A faces the mounting surface 110A substantially parallel to the water discharging device 1 in the installed state. That is, in the water discharging device 1 in the installed state, the water discharging pipe 10 has its base end surface 10A facing the attached surface 110A, and extends obliquely upward at a predetermined angle from the base end side toward the distal end side. As shown in FIG. 6, the proximal end surface 10A has a substantially circular shape when viewed from the bottom. As shown in FIG. 7, the distal end surface 10B, which is the end surface on the upper end side of the water discharge pipe 10, is formed of a surface that is substantially perpendicular to the central axis C, which is a surface that extends in the vertical and horizontal directions.

The water discharge pipe 10 forms a water passage inside. Specifically, the water discharge pipe 10 is formed into a tubular shape having a peripheral wall 11. As shown in FIG. 2, the water discharge pipe 10 accommodates a water supply hose 70 forming a water passage in an internal space. The base end side of the water supply hose 70 extends downward through the attached portion 110 and is connected to a solenoid valve (not shown). The distal end side of the water supply hose 70 is connected to a water spout member 21 of a water spouting section 20, which will be described later.

As shown in FIG. 7, the inside of the water discharge pipe 10 has a plurality of spaces arranged in the direction of the central axis C in the order of a first space R1, a second space R2, and a third space R3 from the proximal end toward the distal end. divided into spaces. The first space R1 communicates with the external space through an opening R1A that opens in the base end surface 10A of the water discharge pipe 10. A mounting portion 40, which will be described later, is inserted into the opening R1A. The edge of the opening R1A forms the above-mentioned base end surface 10A. The second space R2 communicates with the external space through an opening R2A that opens on the lower surface side of the outer peripheral surface of the peripheral wall 11. The opening R2A is an opening in which the water spouting part 20 is provided. A water spout member 21 of a water spout section 20, which will be described later, is inserted into the opening R2A. The third space R3 communicates with the external space through an opening R3A that opens at the distal end surface 10B of the water discharge pipe 10. A water discharge operation section 30, which will be described later, is inserted into the opening R3A. The edge of the opening R3A forms the above-mentioned tip surface 10B.

The water discharge pipe 10 is provided so that, in a cross section orthogonal to the direction of the central axis C, which is the extending direction, the ratio of the width in the vertical direction in the aspect ratio increases toward the upper end. In a cross section perpendicular to the central axis C, the water discharge pipe 10 is wide in the left-right direction at the base end side, as shown in FIG. In a cross section orthogonal to the center axis C, the water discharge pipe 10 has a circular cross section with substantially the same aspect ratio at the middle portion in the direction of the center axis C, as shown in FIG. In a cross section perpendicular to the central axis C, the water discharge pipe 10 is wide in the vertical direction at the upper end side, as shown in FIG. In this manner, the cross-sectional shape of the water discharge pipe 10 changes in a cross section orthogonal to the central axis C, with the horizontal width becoming smaller and the ratio of the vertical width to the horizontal width increasing toward the top end side. . As described above, the width of the water discharge pipe 10 in the vertical direction is approximately the same from the base end side to the distal end side, and the width in the left and right direction tapers toward the distal end side. Therefore, in the cross-sectional shape of the water discharge pipe 10 in the direction of the central axis C, the width in the left-right direction changes more than the width in the vertical direction.

As mentioned above, the water discharge pipe 10 is formed by die-casting. In the water discharge pipe 10, each of the internal spaces R1, R2, and R3 corresponds to a portion into which a slide mold was inserted during molding. The slide mold forming the first space R1 and the third space R3 slides along a direction corresponding to the direction of the central axis C of the water discharge pipe 10. The slide mold forming the second space R2 slides in a direction orthogonal to a direction corresponding to the direction of the central axis C of the water discharge pipe 10. In the water discharge pipe 10 manufactured in this manner, the peripheral wall 11 in the portion forming the first space R1 has a relatively small change in wall thickness in the direction along the central axis C, although the so-called draft angle is taken into consideration. becomes possible. That is, since the slide mold forming the first space R1 is configured to slide only in the direction of the central axis C, the thickness of the peripheral wall 11 above the opening R1A in the direction of the central axis C is equal to the thickness of the peripheral wall 11 at the opening R1A.

As a result, the attached portion 110 is sandwiched between the lower end portion of the water discharging device 1 and the fixing washer 80, and the water discharging device 1 is fixed to the attached portion 110.

The effects of the water discharging device 1 having the above configuration will be explained.

The water spouting device 1 automatically spouts water when the sensor 22 detects an object such as a user's hand held out in front of the water spouting unit 20, and operates the press operation unit 35 of the water spouting operation unit 30 by pressing. Water can be spouted in two ways: manual water spouting and manual water spouting. The water spouting device 1 can switch between two water spouting states of water spouting and hot water spouting when discharging both automatic water spouting and manual water spouting by pressing the press operation part 34 of the water spouting operation part 30. It is.

In the water discharging device 1, when water adheres to the distal side of the water discharging portion 20, such as the water discharging operation portion 30 or the upper end of the water discharging pipe 10, water flows toward the proximal end along the outer circumferential surface of the water discharging pipe 10. . The water flowing along the outer circumferential surface of the water spout 10 is separated from the outer peripheral surface of the water spout 10 and falls at a drain section 60 provided on the lower surface side of the water spout 10. Specifically, the water that flows along the outer circumferential surface of the water discharge pipe 10 and reaches the drain section 60 is separated from the outer circumferential surface of the water discharge pipe 10 at the corner 60A and falls onto the bowl surface 100A.

As described above, the water discharging device 1 includes the water discharging pipe 10, the water discharging section 20, and the draining section 60. The water discharge pipe 10 is provided to extend obliquely upward from the base end toward the distal end, and accommodates a water supply hose 70 that forms a water passage therein. The water spouting part 20 is provided on the lower surface side of the water spouting pipe 10, and has a water spout 20A that discharges water via the water supply hose 70. The draining section 60 is a portion of the water discharging pipe 10 that is closer to the tip than the water discharging section 20 and is provided on the lower surface side of the water discharging pipe 10 . The draining portion 60 has a corner portion 60A. The corner portion 60A is provided so as to separate water flowing toward the base end along the outer circumferential surface of the water discharge pipe 10 from the outer circumferential surface of the water discharge pipe 10. In this manner, the water discharging device 1 prevents water flowing along the outer peripheral surface of the water discharging pipe 10 from adhering to the water discharging portion 20 forming the water discharging port 20A, or flowing to the lower end of the water discharging pipe 10 and reaching the attached surface 110A. This can prevent stagnation. Therefore, the water discharging device 1 can maintain good sanitary conditions.

The corner portion 60A is a part of the peripheral edge of the opening R2A, which is an opening formed on the lower surface side of the water spouting pipe 10 and in which the water spouting portion 20 is provided. In this manner, the water spouting device 1 utilizes a part of the opening for providing the water spouting portion 20 in providing the water draining portion 60, so that a configuration including the water draining portion 60 can be easily realized.

The water spouting part 20 is configured by arranging a water spout member 21 in which a water spout 20A is formed in an opening R2A. For this reason, the water spouting device 1 can easily form the water spout compared to the case where the water spout is directly formed in the water spout pipe.

In the upper end portion of the spout member 21, an acute angle is formed between the front surface 23A of the front wall portion 23, which is the front end surface, and the peripheral wall surface 23C of the front wall portion 23, which is the upper end surface. Therefore, even if water flows from the corner 60A to the water spout member 21, the water is separated at the upper end portion of the water spout member 21 and can be prevented from being transmitted to the water spout 20A.

The discharging pipe 10 has a base end surface 10A, which is a lower end surface, having a substantially circular shape, and the aspect ratio in a cross section orthogonal to the direction of the central axis C, which is the extending direction, is such that the ratio in the vertical direction becomes larger toward the upper end. It is provided. Therefore, a water discharge pipe with good design can be realized.

The water discharging device 1 includes a water discharging operation section 30. The water spouting operation unit 30 is provided at the upper end of the water spouting pipe 10, and is used to perform an operation for switching the discharge state of water discharged from the water spout 20A. Therefore, in the water discharging device 1, the water discharging state can be changed more easily than when the water discharging operation section is located on the proximal end side of the water discharging pipe.

The water discharging operation section 30 has a plurality of pressure operation sections 34 and 35, and the plurality of pressure operation sections 34 and 35 are arranged at the upper end of the water discharging device 1 along a central axis that is the extending direction of the water discharging pipe 10 in a side view. A plurality of them are arranged in a direction perpendicular to the C direction, that is, in the vertical direction. In this way, since the plurality of pressure operation parts 34, 35 as water spouting operation parts are arranged vertically at the upper end portion formed vertically, the number of pressure operation parts 34, 35 is smaller than when the pressure operation parts 34, 35 are arranged horizontally. Sufficient space can be secured between them. Therefore, it is possible to improve the operability of the water discharging operation section.
