  Hereinafter, the water discharging apparatus according to the present embodiment will be specifically described with reference to the drawings.

  Drawing 1 is an explanatory view showing the shower room provided with the water discharging apparatus concerning this embodiment. As shown in FIG. 1, the wall W of the shower room includes an upper shower 1 provided above the head of the user P and a hand shower provided at a position substantially at the height of the chest of the user P. 2 and.

  Moreover, the control panel 3 is arrange | positioned by the wall W, and the user P takes out and stops water and warm water from the upper shower 1 or the hand shower 2 by operating this control panel 3. It is configured to be able to.

  As a characteristic configuration of the present embodiment, the wall body W is provided with two water discharge devices A at the positions of the chest height and the waist height of the user P. By appropriately adjusting the water discharge device A, the hot water is jetted in a desired direction such as the chest and waist of the user P.

  The water discharge device A is also configured to be capable of discharging and stopping hot water and adjusting the temperature of hot water by the control panel 3.

  As shown in FIG. 2, the water discharge device A includes a chamber 11 having a water supply port 10, a spherical member 13 accommodated in the chamber 11, a base portion in the spherical member 13, and a plurality of water discharge ports 15. The hot water supplied from the water supply port 10 is supplied from the chamber 11 to the self-revolving nozzle 12 via the spherical member 13, and formed at the tip of the self-revolving nozzle 12. Water can be discharged from a plurality of water outlets 15.

  Further, as one of the features of the water discharge device A, the spherical member 13 having a self-revolving nozzle 12 built therein, such as a so-called ball joint, can be swung in all directions with respect to the chamber 11. By appropriately adjusting the angle of the self-revolving nozzle 12 via the spherical member 13 in advance, water can be discharged in a desired direction.

  Further, as another feature of the water discharger A, the self-revolving nozzle 12 is supported in a freely rotating state in a free end state inside the spherical member 13, and hot water is supplied from the water supply port 10. At this time, the revolving nozzle 12 performs a revolving motion and a revolving motion with a midway abutting engagement portion as a fulcrum so that a spiral water flow can be discharged toward the user P.

  Next, the water discharge device A of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 3 and 4, the water discharger A stores the spherical member 13 in the internal space of the chamber 11 composed of the upper chamber 18 and the lower chamber 19, and the swirl chamber 20 formed inside the spherical member 13. In this case, the lower half of the cylindrical self-revolving nozzle 12 provided with a water supply passage 48 is accommodated, and a water discharge part 21 is connected to the tip of the self-revolution nozzle 12 to provide the water discharge part 21. Hot water can be discharged from the water outlet 15.

  In addition, the self-revolving nozzle 12 is rotated around the axis of the self-revolving nozzle 12 by the flow of hot water flowing into the swirl chamber 20 inside the spherical member 13, and the axis is back and forth, right and left, and By displacing in the circumferential direction and revolving the self-revolving nozzle 12, the spray water is automatically discharged from the spout 15 into the peripheral surface of the virtual conical shape and the inside thereof, and it is dense over a wide area. It is configured to enable proper jet water discharge.

  As shown in FIGS. 2 and 4, the chamber 11 includes a cylindrical upper chamber 18 that is open downward and a cylindrical lower chamber 19 that is open upward, and the upper and lower chambers 18 and 19 are screwed together on the peripheral wall surface. Thus, an integral hollow chamber 11 is formed.

  In addition, a water supply port communicating with the water supply pipe is formed at the center of the bottom surface of the lower chamber 19, and a receiving portion 23 for holding a pressing member 22 described later is formed on the inner bottom surface.

  An annular pressing member 22 is placed on the inner bottom surface of the lower chamber 19 via a coil spring 24 as a biasing means for biasing the chamber 11 toward the opening 32.

  As shown in FIG. 5, the pressing member 22 forms a receiving surface 31 having a curved upper end surface having a water passage hole 25 in the center, and is brought into contact with a spherical member 13 described later as a contact portion. It is formed so as to function, and a receiving surface flange 26 is provided on the outer periphery thereof, and a base peripheral wall 27 is provided below it.

  In addition, the receiving surface flange 26 and the base peripheral wall 27 are formed with a flange notch 28 and a base notch 29 that are notched at regular intervals, and these notches 28 and 29 are used for supplying water to the lower chamber 19. A water passage 30 is formed to guide hot water flowing from the port 10 into the chamber 11.

  The water flow portion 30 is formed with a plurality of grooves in the radial direction on the receiving surface 31 of the annular pressing member 22, and the hot water in the water flow hole 25 portion passes through the grooves described above to receive surface flange 26. You may comprise so that it may flow above.

  The coil spring 24 is mounted so as to surround the outer periphery of the base peripheral wall 27 so as to be interposed between the lower surface of the receiving surface flange 26 of the pressing member 22 and the inner bottom surface of the lower chamber 19, and the pressing member 22 is attached upward. It is fast.

  A spherical member 13 having a spherical surface is slidably accommodated in the space in the chamber 11, and the lower half spherical surface of the spherical member 13 is in contact with the receiving surface 31 in surface contact. The upper hemispherical surface 13 is loosely fitted into an opening 32 formed in the ceiling wall of the upper chamber 18.

  In the opening 32, a receiving surface 33 that is in surface contact with the spherical surface of the spherical member 13 is formed in a concave spherical shape at the center of the ceiling wall of the upper chamber 18.

  Therefore, the spherical member 13 is loosely fitted and held between the receiving surface 31 of the holding member 22 biased upward by the coil spring 24 and the receiving surface 33 of the opening 32 of the upper chamber 18, and is incorporated in the swirl chamber 20. It is in the state.

  As shown in FIG. 6 (a), a pair of right and left water inlets 34 are pivoted on the substantially central peripheral surface of the spherical member 13 symmetrically about the central axis passing through the center point Q of the lower hemisphere 37 in the vertical direction. The chamber 20 and the outside of the spherical member 13 are formed so as to communicate with each other, and a rectangular recess-shaped counterbore 35 is formed as a communication path around the water inlet 34 in the chamber 11. The fluid supplied to the inside swirl chamber 20 is guided so as to be easily guided to the water inlet 34, and functions to increase the flow force.

  In addition, the counterbore part 35 is close to the water passage part 30 described above, and hot water flowing into the chamber 11 through the water passage part 30 can be efficiently guided into the spherical member 13.

  The counterbore part 35 formed along the circumferential surface of the spherical member 13 is formed longer than the width D of the receiving surface 31 of the pressing member 22 shown in FIG. 5, and the user P turns the spherical member 13 around. The counterbore part 35 is exposed from above the water passage hole 25 and the receiving surface flange 26 even when the operation is performed, so that hot water can be guided to the water inlet 34.

  The spherical member 13 is configured as an integral spherical shape by screwing the upper and lower hemispherical upper and lower hemispheres 36 and 37 together. Further, the upper hemisphere 36 is made of metal in order to maintain watertightness with the O-ring 53 disposed above the inside of the chamber 11, and is specifically made of stainless steel. This makes it possible to form an accurate spherical surface, and to keep the spherical surface as accurate as possible for a long time, thereby preventing water leakage.

  As shown in FIGS. 4, 7, and 8, the spherical member 13 is hollow and forms a swirl chamber 20. The swirl chamber 20 is a substantially cylindrical space, and the upper end of the swirl chamber 13 is a spherical member 13. A cylindrical nozzle guide 39 is provided in the upper half of the swirl chamber 20 to form an inner peripheral wall of the upper half of the swirl chamber 20.

  The nozzle guide 39 is formed of a resin having good slipperiness, specifically, a fluororesin. As shown in FIG. 8, a circular hole 40 is formed in the ceiling wall, and the periphery of the circular hole 40 is engaged. In addition to the flange 41, the lower end of the nozzle guide 39 is open, and a base flange 42 projects from the periphery.

  The base flange 42 can be fixed to the upper half of the swirl chamber 20 by placing the base flange 42 on a step 43 formed in the middle of the swirl chamber 20 of the spherical member 13.

  In the swirl chamber 20 of the spherical member 13, a self-revolving nozzle 12 having a water supply passage 48 serving as a water supply conduit is housed so as to rotate and revolve freely.

  That is, the self-revolving nozzle 12 includes a cylindrical nozzle body 44 that is open downward, a reduced diameter portion 45 that has a reduced diameter at the upper portion thereof, and a disc-shaped water discharge portion 21 that is continuously provided at the tip thereof.

  The reduced diameter portion 45 is made of metal, specifically stainless steel, and improves the strength of the relatively thin reduced diameter portion 45 that always contacts the nozzle guide 39 by rotating and revolving during water discharge. I am doing so. Further, as will be described later, even when the self-revolving nozzle 12 is pressed by mischief or the like, the thin reduced diameter portion 45 can be protected. If the nozzle guide 39 described above is made of metal, there is a problem that relatively large vibrations occur due to contact with the reduced diameter portion 45 made of metal. Such a problem can be avoided because it is formed by molding with resin.

  The nozzle main body 44 is opened at the lower side to serve as a water supply section 47, and a large number of hot water inlets 46 are provided at regular intervals on the midway surface thereof, so that the hot water flowing into the swirl chamber 20 of the spherical member 13 is formed. Is configured to flow into the self-revolving nozzle 12 from the water supply section 47 at the lower end and the inlet 46 on the peripheral surface.

  The nozzle body 44 is positioned at the upper end of the nozzle body 44 because its upper half is inserted into the nozzle guide 39 and its lower half is housed in the swirl chamber 20. The reduced diameter portion 45 is in a state of being inserted and projected into the circular hole 40 of the nozzle guide 39.

  In addition, since the reduced diameter portion 45 is in a contact engagement state with a certain gap held in the engagement flange 41 at the periphery of the circular hole 40, when the nozzle body 44 swings, that is, rotates and revolves, With the abutting engagement portion between the engagement flange 41 and the reduced diameter portion 45 as a substantial fulcrum, the water discharger 21 at the tip is swung in a revolution form.

  Moreover, since the lower half of the nozzle body 44 has a peripheral surface facing the water inlet 34 in the swirl chamber 20 of the spherical member 13, a pair of water inlets 34 of the lower hemisphere 37 as shown in FIG. When hot water flows from the swirl chamber 20 into the swirl chamber 20, a swirl flow is generated and becomes a swirl, and the nozzle body 44 rolls along the inner cylinder wall of the inner tube swirl chamber 20, and simultaneously rotates. The movement of the nozzle body 44 due to the inflow of hot water from the water inlet 34 causes the rotation and revolution of the rotation / revolution nozzle 12 to occur.

  Moreover, the hot water from the water inlet 34 that has been rotated and revolved on the nozzle body 44 of the revolution nozzle 12 flows from the water supply section 47 of the nozzle body 44 and the inlet 46 on the peripheral surface of the nozzle body 44, and rotates and revolves. It flows out to the water discharge part 21 through the water supply channel 48 of the nozzle 12.

  The terminal end of the water supply path 48 of the self-revolving nozzle 12 is communicated with the water discharge port 15 of the water discharge unit 21. That is, the water discharger 21 is threadedly connected to the upper end of the self-revolving nozzle 12, and a large number of rectifying plates 49 are erected radially at regular intervals from the center in the hollow interior of the water discharger 21. The space between the plates 49 is communicated with a large number of water discharge ports 15 so that the fluid fed from the water feed passage 48 of the revolution nozzle 12 does not deviate regardless of the revolution operation of the revolution nozzle 12. It is configured so that water is ejected from each water outlet 15 evenly.

  That is, the rectifying plate 49 has a role of eliminating the swirling component of the swirling flow generated in the swirling chamber 20 of the hot water flowing through the water supply channel 48 toward the water discharger 21.

  In addition, as shown in FIG. 9, the water discharge path 52 which reaches the water discharge port 15 formed in the water discharge section 21 is not perpendicular to the disk surface of the disk-shaped water discharge section 21, and any of the water discharge paths 52 are directed in a predetermined direction. In addition, the inclined spout 15 is formed with a constant inclination angle α, and the substantially conical fountain form by the revolution of the fountain portion 21 is further expanded by the inclined fountain 15 so that the conical fountain has a wide range. Can be obtained.

  In other words, each of the water discharge channels 52 is formed in the same direction with a constant inclination angle α with respect to the nozzle central axis of the self-revolving nozzle 12 so that, for example, hot water is discharged like a searchlight. Thus, the water can be discharged over a wide range, and the density of the discharged water can be made dense to give the user P an image of being bathed with hot water throughout the body. Moreover, it has the effect of aligning the flux of hot water to be discharged and increasing the reaction to promote the rotation operation.

  The embodiment of the present invention is configured as described above, and its operation will be described. First, when hot water is supplied from the water supply pipe to the water supply port, it flows into the chamber 11.

  In the chamber 11, first of all, it interferes with the pressing member 22 at the start end in the chamber 11, but as shown in FIGS. 4 and 7, the water is passed from the water passing portion 30 of the pressing member 22, and the chamber 11 flows into the inner space, and flows into the water inlet 34 on the circumferential surface of the spherical member 13 using this inflow pressure.

  As shown in FIGS. 6 and 7, the water inlet 34 is formed symmetrically with a pair of left and right axes, and thus swirls into the swirl chamber 20 of the spherical member 13 by the flow of hot water flowing from the respective water inlets 34. Generate a flow.

  The revolving motion of the self-revolving nozzle 12 is given by the swirling flow pushing the lower end portion of the nozzle body 44, and the revolving nozzle 12 is centered around the reduced diameter portion 45 as shown in FIGS. As described above, the spherical member 13 rotates while being inclined with respect to the central axis. At this time, since the guide surface 55 of the nozzle guide 39 and the contact surface 56 of the nozzle body 44 rotate in contact with each other, the inclination angle of the self-revolving nozzle 12 depends on the inclination angle of the guide surface 55 of the nozzle guide 39, An angle β is formed. Therefore, the inclination angle of the self-revolving nozzle 12 can be controlled by setting the inclination angle of the guide surface 55 of the nozzle guide 39.

  Further, the rotation motion of the self-revolving nozzle 12 is given by the frictional resistance when the guide surface 55 of the nozzle guide 39 and the contact surface 56 of the nozzle body 44 come into contact with each other. At this time, the rotation direction of the rotation / revolution nozzle 12 is opposite to the rotation direction of the rotation.

  The rotational speed of the revolution / revolution of the revolution / revolution nozzle 12 depends on the flow velocity of the swirl flow in the swirl chamber 20, but the flow velocity of the swirl flow can be controlled by changing the setting of the opening area of the water inlet 34.

  By the operation of the self-revolving nozzle 12, the water discharger 21 also rotates and revolves, and the jet water is discharged from the water outlet 15.

  In particular, the movement of the water discharger 21 is a revolution with the contact engagement part between the reduced diameter part 45 and the engagement flange 41 as a substantially fulcrum. In addition, since the water discharge part rotates, water is discharged densely inside the substantially conical range, and the density of the discharged water is eliminated within the water discharge range, and the washing efficiency and pressure on the human body by the water discharge shower are eliminated. It is possible to improve the stagnation efficiency.

  When changing the direction of water discharge, as shown in FIGS. 10 and 11, the spherical member 13 is rotated in the chamber 11 while holding the water discharge portion 21 protruding from the wall W by hand. In this case, as shown in FIG. 11, the spherical member 13 is pressed together with the pressing member 22 against the urging force of the coil spring 24 via the water discharger 21 in advance. When the lower end of the base peripheral wall 27 of the member 22 is brought into contact with the receiving portion 23 on the inner bottom surface of the lower chamber 19, the spherical surface of the upper hemisphere 36 of the spherical member 13 and the receiving surface 33 of the opening 32 of the upper chamber 18 are interposed. Since the gap is formed, an operation of easily displacing the direction of the auto-revolution nozzle 12 together with the spherical member 13 is performed.

  Further, even when the water discharger 21 is pressed due to mischief or the like, since the self-revolving nozzle 12 sinks into the chamber 11 together with the spherical member 13, the load applied to the reduced diameter portion 45 is dispersed and the water discharger A Can be hard to break.

  As described above, according to the water discharging device according to the present invention, the cleaning water in the chamber is caused to flow from the chamber to which the cleaning water is supplied from the outside and the water inlet provided on the peripheral surface to generate a swirling flow. A swirl chamber is provided inside, and a circular hole communicating the swirl chamber and the outside is formed in the peripheral surface, and the circular hole is stored in the chamber in a state exposed from an opening formed in the chamber. And a spherical member rotatably supported by the inner peripheral surface of the chamber in a state in which the opening cannot be removed, and a reduced diameter portion inserted through the circular hole, and a tip of the reduced diameter portion A water discharge portion provided on the side protrudes from the circular hole, a water supply portion provided on the rear end side of the reduced diameter portion is accommodated in the swirl chamber in a free end state, and the wash water flowing from the water supply portion is discharged into the water discharge portion. A cylindrical nozzle that can be discharged from a portion, and The cylindrical member can be swung in all directions with respect to the chamber, and the cylindrical nozzle has at least a part of the reduced diameter portion formed by the swirl flow formed in the swirl chamber. Since it revolves around the central axis of the circular hole in contact with the peripheral edge of the nozzle, the direction of the nozzle can be arbitrarily adjusted by the user, and hollows can be prevented, and as little as possible It is possible to provide a water discharger that can spray water over a wide range at a flow rate.

  Finally, the description of each embodiment described above is an example of the present invention, and the present invention is not limited to the above-described embodiment. For this reason, it is a matter of course that various modifications other than the above-described embodiments can be made according to the design and the like as long as they do not depart from the technical idea according to the present invention.

  For example, in this embodiment, the water passage 30 is configured by notching the receiving surface flange 26 and the base peripheral wall 27 of the pressing member 22 and forming the flange notch 28 and the base notch 29. For example, the water passage 30 may be configured by providing a hole penetrating the receiving surface flange 26 and the base peripheral wall 27.

  Specifically, as shown in FIG. 12, the pressing member 50 does not form the flange cutout portion 28 in the receiving surface flange 26, and a large number of small holes are formed at regular intervals to form the flange water holes 51. The flange water passage hole 51 is in communication with the space of the base notch 29 of the base peripheral wall 27.

  Even with this configuration, the hot water supplied from the water supply port 10 can be smoothly allowed to flow into the chamber 11.
