The water discharging apparatus disclosed in Patent Document 1 can discharge water over a wide range with a small amount of water by discharging water while swinging and revolving the nozzle.
However, a gap is required between the inflow chamber and the nozzle to swing and revolve the nozzle, and a slight amount of leakage water is generated from the gap. Get out. Further, when the head is attached to the tip of the nozzle, leaked water travels through the nozzle, and fine water droplets are scattered on the circumference along the inclination of the head. Because of the fine water droplets, it is easy to dissipate heat, and when it touches the human body, it becomes cold water discharge and gives an unpleasant feeling.

  This invention is made in view of the above-mentioned problem, and provides the water discharging apparatus which can prevent scattering of the fine water droplet by rotation of a nozzle.

  According to one aspect of the present invention, there is provided a guide member having an inflow chamber into which cleaning water flows, an opening that communicates the inside and the outside of the inflow chamber, and a reduced diameter portion that is smaller in diameter than the opening. The reduced diameter portion is provided inside the inflow chamber in a state in which the tip of the reduced diameter portion protrudes from the opening to the outside of the guide member, and the washing water that has flowed into the inflow chamber flows out from the front end of the reduced diameter portion. A cylindrical body having a possible water outlet, and the cylindrical body is inclined with respect to a central axis of the inflow chamber in a state where at least a part of the reduced diameter portion is in contact with the opening. Characterized in that it swings and revolves around a central axis, and the cylindrical body rotates around its own central axis and has a rib portion extending radially and at the opening side at the tip of the reduced diameter portion. A water discharge device is provided.

  ADVANTAGE OF THE INVENTION According to this invention, when discharging water while swinging and revolving a nozzle, or rotating, a water discharging apparatus which can prevent scattering of the fine water droplet by rotation of a nozzle is provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1: shows the schematic cross section of the water discharging apparatus which concerns on embodiment of this invention.
The water discharge device according to the present embodiment mainly includes a guide member 1, a cylindrical body 20, and a rib portion 26.

  The guide member 1 has a structure in which a through hole is formed inside the sphere 2. An inflow chamber 3 extending in the diameter direction of the sphere 2 is formed inside the sphere 2. At one end in the axial direction of the inflow chamber 3, an opening 4 is provided that communicates with the inside and the outside of the inflow chamber 3. The inner diameter of the opening 4 is smaller than the inner diameter of the inflow chamber 3, and the center of the opening 4 is aligned with the central axis of the inflow chamber 3. An inflow hole 5 is formed outside the diameter of the inflow chamber 3 on the other end side in the axial direction. The inflow hole 5 communicates with the inside of the inflow chamber 3 and the outside of the sphere 2. The washing water introduced from the outside of the guide member 1 to the inflow hole 5 flows in the tangential direction with respect to the inflow chamber 3 through the inflow hole 5, and a swirling flow of the cleaning water is formed inside the inflow chamber 3. The The opening 4 is open to the outside of the guide member 1, and the opening on the other end side of the inflow chamber 3 is closed by a sealing member 6.

  The cylindrical body 20 is formed in a substantially bottle shape having a reduced diameter portion 21 and a large diameter portion 22, and the outer diameter size of the large diameter portion 22 is smaller than the inner diameter size of the inflow chamber 3. Housed inside the chamber 3. The outer diameter dimension of the reduced diameter part 21 provided integrally with the large diameter part 22 is smaller than the inner diameter dimension of the opening part 4, and the reduced diameter part 21 penetrates the opening part 4, and the tip thereof is outside the spherical part 2. Protruding. The diameter-reduced portion 21 is provided with a water outlet 25 that is inclined and communicated with the central axis C1 of the cylinder, and a rib portion 26 is provided at the distal end of the diameter-reduced portion 21 so as to extend radially and toward the opening. It has been.

  As shown in FIG. 1, in a state where the cylindrical body 20 and the inflow chamber 3 are aligned with each other in the center axis, a gap is formed between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening portion 4. Further, a gap is also formed between the outer peripheral surface of the large diameter portion 22 and the inner wall surface of the inflow chamber 3. The cylindrical body 20 is not fixed to the guide member 1 and can swing and revolve freely so as to rotate and swing freely.

  Both ends of the cylindrical body 20 in the axial direction are opened, and the cleaning water flowing into the cylindrical body 20 from the opening 24 on the large diameter portion 22 side flows in the cylindrical body 20 in the axial direction and communicates with the reduced diameter portion 21. The water can be discharged from the water outlet 25 to the outside of the cylindrical body 20. In addition, a plurality of through holes 23 that are intermittently arranged at equal intervals in the circumferential direction are formed on the circumferential surface (side surface) of the large-diameter portion 22 of the cylindrical body 20, and the washing water that has flowed into the inflow chamber 3 Even through the through holes 23, the water can be discharged from the water discharge port 25 that is guided into the cylindrical body 20 and communicates with the reduced diameter portion 21.

  The water discharge port 25 is inclined not in parallel with the central axis C <b> 1 of the cylindrical body 20 in the axial direction. Therefore, the water discharge port 25 is inclined in an asymmetric relationship with respect to the central axis C <b> 1 of the cylindrical body 20. That is, the inclination direction of the water discharge port 25 does not coincide between when the cylinder 20 is rotated 180 degrees around the central axis C1 around the central axis C1 and before it is rotated 180 degrees.

  Next, the operation of the water discharge device according to the present embodiment and the movement (trajectory) of the water discharge flow will be described.

  FIG. 2 is a schematic view of the above-described inflow chamber 3 and the cylindrical body 20 (the large diameter portion 22) accommodated therein, as viewed from the plane direction, and corresponds to the AA-AA cross section in FIG.

  Wash water (including hot water) guided from a pipe or the like (not shown) flows into the inflow chamber 3 having a substantially circular cross section from the tangential direction through the inflow hole 5 formed in the guide member 1. Thus, a flow of cleaning water swirling around the central axis C <b> 2 of the inflow chamber 3 is formed inside the inflow chamber 3.

  The cylindrical body 20 (the large-diameter portion 22) housed in the inflow chamber 3 receives the swirling flow force, and as shown in FIG. 3, is tilted with respect to the central axis C2 of the inflow chamber 3, For example, it revolves around the central axis C2 of the inflow chamber 3 in the direction indicated by the arrow A in FIG. As shown in FIG. 3, a part of the reduced diameter portion 21 of the cylindrical body 20 contacts the opening 4, and a part of the side surface (circumferential surface) of the large diameter portion 22 contacts the guide surface 3 a of the inflow chamber 3. By doing so, further inclination of the cylinder 20 with respect to the central axis C2 of the inflow chamber 3 is regulated.

  In the present specification, the revolving around the central axis C2 while the cylindrical body 20 is inclined with respect to the central axis C2 of the inflow chamber 3 is referred to as “swing swing revolution”. That is, when the cylindrical body 20 revolves around the central axis C2 while tilting with respect to the central axis C2 of the inflow chamber 3, the cylindrical body 20 is contracted around the vicinity of the portion where the reduced diameter portion 21 contacts the opening 4. It swings so that the tip of the diameter portion 21 swings its head.

  When the tubular body 20 swings and revolves, a part of the outer peripheral surface of the reduced diameter portion 21 is in contact with the inner wall surface of the opening 4 and a part of the side surface (peripheral surface) of the large diameter portion 22 is an inflow chamber. Since the three guide surfaces 3 a are in contact with each other, the dynamic friction force generated in the contact portions acts on the cylindrical body 20. Due to this dynamic frictional force, the cylinder 20 does not slide and move in the inflow chamber 3 in the state where it is in contact with the opening 4 and the guide surface 3a without changing the contact portion. And swing around the guide surface 3a. The fact that the cylindrical body 20 rolls on the inner wall surface of the opening 4 or the guide surface 3a means that the cylindrical body 20 rotates around its own central axis C1.

  That is, the cylindrical body 20 swings and revolves around the central axis C2 of the inflow chamber 3 while rotating about the central axis C1 thereof. The revolution direction (in the direction of arrow A in FIG. 2) of the cylinder 20 around the central axis C2 of the inflow chamber 3 is the same as the swirl direction of the swirl flow formed in the inflow chamber 3, and the cylinder 20 itself The direction of rotation around the central axis C1 (the direction of arrow B in FIG. 2) is opposite to the direction of revolution A. Regarding this rotation, the dynamic friction coefficient of the contact surface, the material and shape of the large-diameter portion 22 of the cylindrical body 20, the inflow speed from the inflow hole 5, the gap between the inflow chamber 3 and the large-diameter portion 22, etc. The rotation direction and the number of rotations can be controlled.

  A part of the washing water that has flowed into the inflow chamber 3 flows into the inside of the cylinder 20 from the opening 24 at the end of the cylinder 20 on the side of the large diameter portion 22 and the through-hole 23 formed on the side surface. 20 flows in the axial direction toward the tip of the reduced diameter portion 21 and is discharged to the outside.

  Since the cylindrical body 20 moves in combination with swinging revolution and rotation as described above, the water discharge trajectory of the water discharge flow obtained by the water discharge device according to the present embodiment (for example, the human body at the collision site of the water discharge flow with respect to the human body etc. The movement trajectory on the surface) is a combination of a trajectory due to rotation and a trajectory due to swing swing.

  The water discharge locus is schematically shown in FIG. In FIG. 4, the water discharger shows only the cylindrical body 20 that is a movable part, and the guide member 1 in which the inflow chamber 3 is formed is omitted from the illustration.

  The cylindrical body 20 and the head 40 rotate together with each other around their own central axis C1, and move in the same b direction as the rotation direction while drawing a circular locus as shown by a solid line in FIG. A water stream is formed. Here, since the water discharge port 25 is inclined with respect to the central axis C1 of the cylindrical body 20, the water discharge flow moves so as to draw a circle larger than the diameter of the cylindrical body 20 in which the water discharge port 25 is formed.

  Here, as a comparative example, when the water discharge port 25 is parallel to the central axis C1 of the cylindrical body 20, a discharged water flow having a symmetric spread with respect to the central axis C1 is discharged, and the cylindrical body 20 and the head Even if 40 rotates around the central axis C1, the water discharge continues to hit the same part of the human body or the like.

  On the other hand, in the present embodiment, since the plurality of water discharge ports 25 are inclined in an asymmetric relationship with respect to the central axis C1, a water discharge flow having an asymmetrical spread with respect to the central axis C1 is discharged. Along with the rotation of the body 20 and the head 40 around the central axis C1, a portion where the water discharge hits the human body or the like moves around the central axis C1 so that a shower flow can be taken over a relatively wide range. It has become.

  FIG. 6 is a schematic cross-sectional view of a water discharger according to another embodiment of the present invention. FIG. 5 is a schematic cross-sectional view of a water discharge device according to a comparative example. In addition, the same code | symbol is attached | subjected to the same component as embodiment mentioned above, and the detailed description is abbreviate | omitted.

  Here, as described above, a gap is formed between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4 in a state where the cylindrical body 20 and the inflow chamber 3 are aligned with each other. ing. Thereby, the cylindrical body 20 can freely swing and revolve with respect to the guide member 1 to freely rotate or swing. Therefore, the cleaning water that has flowed into the inflow chamber 3 from the inflow hole 54 and has not been able to flow into the cylinder 20 is the outer periphery of the reduced diameter portion 21 as indicated by arrows F and G shown in FIG. In some cases, the air leaks out from the gap between the surface and the inner wall surface of the opening 4.

The washing water 76 leaked to the outside may be scattered in the circumferential direction of the cylinder 20 as shown in FIG. 5 due to the centrifugal force caused by the swing or revolution of the cylinder 20.
The sprayed washing water 76 is subjected to centrifugal force to become fine particles and scatters. Therefore, the temperature is likely to be lowered, and the temperature is lower than the washing water discharged from the water outlet 25. Therefore, when the user bathes the scattered cleaning water 76, the user may feel cold with respect to the cleaning water.
On the other hand, in the water discharging apparatus according to the present embodiment, the cylindrical body 20 has the rib portion 26 as described above. Therefore, even if the cleaning water leaks to the outside as indicated by arrows D and E shown in FIG. 6 through the gap between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4, The water discharge device of this embodiment can suppress the amount of washing water that is scattered by being subjected to centrifugal force to become fine particles.
Therefore, there is little possibility that a user will feel cold with respect to washing water. Therefore, the water discharging apparatus of this embodiment can warm a human body etc., without giving a user discomfort.

Next, a second embodiment of the present invention will be described.
FIG. 7: shows the schematic cross section of the water discharging apparatus which concerns on embodiment of this invention.
The water discharge device according to the present embodiment mainly includes a guide member 1, a cylindrical body 20, a rib portion 26, and a head.

  The configuration in which the cylindrical body 20 is housed inside the guide member 1 and the rib portion 26 extending in the radial direction and toward the opening 4 side of the guide member 1 is provided at the tip of the cylindrical body 20 is the first embodiment. As described above.

  A head 40 is formed at the tip of the reduced neck portion 21 of the cylindrical body 20 described above. The head 40 is formed in a flat shape having a larger radial dimension than the cylinder 20, and the center in the radial direction coincides with the central axis C <b> 1 of the cylinder 20. The head 40 includes a funnel-shaped buffer member 41 and a water spray plate 44. The distal end of the reduced diameter portion 21 of the cylindrical body 20 is fitted and fixed inside the narrow tube portion 42 of the buffer member 41, whereby the cylindrical body 20 and the head 40 are swung together to rotate or swing together. Revolve.

  A buffer chamber 43 is formed inside the buffer member 41, and the opening at the tip of the reduced diameter portion 21 of the cylindrical body 20 faces the buffer chamber 43. The radial dimension of the buffer chamber 43 is larger than the radial dimension of the cylindrical body 20, and the wash water flowing out from the tip of the reduced diameter portion 21 can be temporarily stored in the buffer chamber 43.

  The water spray plate 44 is provided in a lid shape that closes the opening of the buffer chamber 43 on the side opposite to the narrow tube portion 42. The water spray plate 44 is formed in a disk shape having a larger radial dimension than the cylindrical body 20, and the water spray plate 44 has a plurality of water discharge holes 45 penetrating in the thickness direction. One end of the water discharge hole 45 communicates with the buffer chamber 43, and the other end faces the outside of the head 40.

  The plurality of water discharge holes 45 are formed in the circumferential direction in at least the outer peripheral side portion of the water spray plate 44. Each water discharge hole 45 is not parallel to the central axis C <b> 1 of the cylindrical body 20, but is inclined. In this embodiment, all the water discharge holes 45 are inclined in the same direction. Accordingly, each water discharge hole 45 is inclined in an asymmetric relationship with respect to the central axis C <b> 1 of the cylindrical body 20.

  Next, the operation of the water discharge device according to the present embodiment and the movement (trajectory) of the water discharge flow will be described.

  The operation of swinging and revolving around the central axis C2 of the inflow chamber 3 while rotating about the central axis C1 of the cylinder 20 by the action received from the discharged water flow is the same as that of the first embodiment.

  A part of the washing water that has flowed into the inflow chamber 3 flows into the inside of the cylinder 20 from the opening 24 at the end of the cylinder 20 on the side of the large diameter portion 22 and the through-hole 23 formed on the side surface. 20 flows in the axial direction toward the tip of the reduced diameter portion 21 and is discharged to the outside. Then, the washing water that has flowed out from the tip of the reduced diameter portion 21 flows into the buffer chamber 43 inside the head 40. When the cleaning water in the inflow chamber 3 flows into the cylinder 20 and flows through the cylinder 20, it still has a swirl component. Further, when flowing through a relatively narrow flow path called the reduced diameter portion 21, the flow velocity becomes faster.

  Since the buffer chamber 43 is a flat space having a larger radial dimension than the inflow chamber 3 and the cylindrical body 20, the momentum of the cleaning water flowing from the tip of the reduced diameter portion 21 can be reduced. That is, only by temporarily storing the cleaning water in the buffer chamber 43 without adding a special mechanism or parts, the flow rate of the cleaning water can be greatly reduced, and the swirling component can be lost. Since the washing water is rectified in the buffer chamber 43 in this manner, when the water is discharged from the plurality of water discharge holes 45 communicating with the buffer chamber 43 to the outside, the water is discharged in a clean shower shape.

  Since the cylindrical body 20 and the head 40 move in a combination of swinging revolution and rotation as described above, the water discharge trajectory of the shower-like water discharge flow obtained by the water discharge device according to the present embodiment (for example, discharge to the human body or the like). The movement locus on the surface of the human body at the collision site of the water flow) is a combination of a locus caused by rotation and a locus caused by swinging revolution.

  The water discharge locus is schematically shown in FIG. In FIG. 8, the water discharging device shows only the cylindrical body 20 and the head 40 which are movable parts, and the guide member 1 in which the inflow chamber 3 is formed is not shown.

  The cylindrical body 20 and the head 40 rotate together with each other around the central axis C1 of the cylinder 20 and move in the same b direction as the rotation direction in a circular locus as indicated by a solid line in FIG. A water stream is formed. Here, since the water discharge hole 45 inclines with respect to the central axis C1 of the cylinder 20, the water discharge flow moves so as to draw a circle larger than the diameter of the cylinder 20 in which the water discharge hole 45 is formed.

  Here, as a comparative example, when the water discharge hole 45 is parallel to the central axis C1 of the cylinder 20, a water discharge flow having a symmetric spread with respect to the central axis C1 is discharged, and the cylinder 20 and the head Even if 40 rotates around the central axis C1, the water discharge continues to hit the same part of the human body or the like.

  On the other hand, in this embodiment, since the plurality of water discharge holes 45 are inclined with respect to the central axis C1, the water discharge flow having an asymmetrical spread with respect to the central axis C1 is discharged. Along with the rotation of the body 20 and the head 40 around the central axis C1, a portion where the water discharge hits the human body or the like moves around the central axis C1 so that a shower flow can be taken over a relatively wide range. It has become.

  FIG. 9 is a schematic cross-sectional view of a water discharger according to another embodiment of the present invention. FIG. 9 is a schematic cross-sectional view of a water discharge device according to a comparative example. In addition, the same code | symbol is attached | subjected to the same component as embodiment mentioned above, and the detailed description is abbreviate | omitted.

  In this embodiment, the spherical body part 2 is held with respect to the wall 50 of a bathroom or a shower booth through the holding members 51 and 52, for example. A seal ring 55 is interposed between the outer peripheral surface of the spherical portion 2 and the holding member 52, and a seal ring 56 is interposed between the outer peripheral surface of the spherical portion 2 and the holding member 51, and the spherical portion 2 is the holding member. 51, 52 can be rotated in a liquid-tight manner in the vertical direction, the horizontal direction, or the oblique direction. By rotating the sphere 2, the direction in which the surface portion of the water spray plate 44 faces can be changed, and the water discharge direction of the water discharge discharged from the water discharge holes 45 formed in the water spray plate 44 can be adjusted. Become.

  Washing water guided through a pipe (not shown) flows into the holding member 51 from an inflow hole 53 formed in the holding member 51 and then flows into an inflow hole 54 formed in the sealing member 6. Since the downstream side leading to the inflow chamber 3 in the inflow hole 54 formed in the sealing member 6 is inclined with respect to the central axis of the inflow chamber 3, the wash water that has passed through the inflow hole 54 enters the inflow chamber 3. On the other hand, it flows in from the tangential direction and turns in the inflow chamber 3.

  Here, as described above, a gap is formed between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4 in a state where the cylindrical body 20 and the inflow chamber 3 are aligned with each other. ing. Thereby, the cylindrical body 20 and the head 40 can swing and revolve with respect to the guide member 1 freely rotating and swinging. Therefore, the wash water that has flowed into the inflow chamber 3 from the inflow hole 5 and could not flow into the cylinder 20 is the outer periphery of the reduced diameter portion 21 as indicated by the arrows H and I shown in FIG. In some cases, it may be transmitted to the outer peripheral surface of the head 40 through a gap between the surface and the inner wall surface of the opening 4.

The washing water 76 transmitted to the head 40 may be scattered in the circumferential direction of the head 40 as shown in FIG. 9 due to the centrifugal force due to the swinging revolution or rotation of the head 40. Furthermore, even if the cleaning water does not scatter in the circumferential direction of the head 40, the cleaning water 78 collected on the outer peripheral surface of the head 40 may droop as shown in FIG.
The scattered cleaning water 76 and the dripping cleaning water 78 are not the cleaning water temporarily stored in the buffer chamber 43 but the cleaning water transmitted through the outer peripheral surface of the head 40, so that water is discharged from the water discharge hole 45. The temperature is lower than the washed water. Therefore, when the user bathes the scattered cleaning water 76 or the dripping cleaning water 78, the user may feel cold with respect to the cleaning water.

  On the other hand, in the water discharging apparatus according to the present embodiment, the cylindrical body 20 has the rib portion 26 as described above. Therefore, the cleaning water is transmitted to the outer peripheral surface of the head 40 as indicated by the arrow A or the arrow B shown in FIG. 10 through the gap between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4. Even so, the water discharge device of the present embodiment can suppress the amount of cleaning water that scatters in the circumferential direction of the head 40 and the amount of cleaning water that hangs down.

  Thereby, the user can bathe much washing water temporarily stored in the buffer chamber 43 and discharged from the water discharge hole 45. Therefore, there is little possibility that a user will feel cold with respect to washing water. Therefore, the water discharging apparatus of the present embodiment can efficiently warm a wide area such as a human body without giving the user unpleasant feeling.

FIG. 11: shows the schematic cross section of the water discharging apparatus which concerns on the 3rd Embodiment of this invention.
The water discharge device according to the present embodiment mainly includes a guide member 1, a cylindrical body 20, a head 40, and a rib portion 27. The configuration of the guide member 1 is the same as that of the first or second embodiment.

  The cylindrical body 20 is formed in a substantially bottle shape having a reduced diameter portion 21 and a large diameter portion 22, and the outer diameter size of the large diameter portion 22 is smaller than the inner diameter size of the inflow chamber 3. Housed inside the chamber 3. The outer diameter dimension of the reduced diameter part 21 provided integrally with the large diameter part 22 is smaller than the inner diameter dimension of the opening part 4, and the reduced diameter part 21 penetrates the opening part 4, and the tip thereof is outside the spherical part 2. Protruding.

  Both ends of the cylindrical body 20 in the axial direction are opened, and the washing water that has flowed into the cylindrical body 20 from the opening 24 on the large diameter portion 22 side flows in the cylindrical body 20 in the axial direction, from the tip of the reduced diameter portion 21. It can flow out of the cylindrical body 20.

  The head 40 is formed in a flat shape having a larger radial dimension than the cylinder 20, and the center in the radial direction coincides with the central axis C <b> 1 of the cylinder 20. The head 40 includes a funnel-shaped buffer member 41 and a water spray plate 44, and has a rib portion 27 extending on the lower surface of the buffer member 41 in the direction of the opening 4 of the guide member 1. The distal end of the reduced diameter portion 21 of the cylindrical body 20 is fitted and fixed inside the narrow tube portion 42 of the buffer member 41, whereby the cylindrical body 20 and the head 40 are swung together to rotate or swing together. Revolve.

  A buffer chamber 43 is formed inside the buffer member 41, and the opening at the tip of the reduced diameter portion 21 of the cylindrical body 20 faces the buffer chamber 43. The radial dimension of the buffer chamber 43 is larger than the radial dimension of the cylindrical body 20, and the wash water flowing out from the tip of the reduced diameter portion 21 can be temporarily stored in the buffer chamber 43.

  The water spray plate 44 is provided in a lid shape that closes the opening of the buffer chamber 43 on the side opposite to the narrow tube portion 42. The water spray plate 44 is formed in a disk shape having a larger radial dimension than the cylindrical body 20, and the water spray plate 44 has a plurality of water discharge holes 45 penetrating in the thickness direction. One end of the water discharge hole 45 communicates with the buffer chamber 43, and the other end faces the outside of the head 40.

  The plurality of water discharge holes 45 are formed in the circumferential direction in at least the outer peripheral side portion of the water spray plate 44. Each water discharge hole 45 is not parallel to the central axis C <b> 1 of the cylindrical body 20, but is inclined. In this embodiment, all the water discharge holes 45 are inclined in the same direction. Accordingly, each water discharge hole 45 is inclined in an asymmetric relationship with respect to the central axis C <b> 1 of the cylindrical body 20.

Next, the operation of the water discharge device according to the present embodiment and the movement (trajectory) of the water discharge flow will be described.
The operation of swinging and revolving around the central axis C2 of the inflow chamber 3 while rotating around the central axis C1 of the cylinder 20 and the head 40 by the action received from the discharged water flow is as described in the second embodiment. Therefore, the detailed description is abbreviate | omitted.

  Here, as described above, a gap is formed between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4 in a state where the cylindrical body 20 and the inflow chamber 3 are aligned with each other. ing. Thereby, the cylindrical body 20 and the head 40 can swing and revolve with respect to the guide member 1 freely rotating and swinging. Therefore, the cleaning water that has flowed into the inflow chamber 3 from the inflow hole 5 but could not flow into the cylinder 20 is the outer periphery of the reduced diameter portion 21 as indicated by the arrows H and I shown in FIG. In some cases, it may be transmitted to the outer peripheral surface of the head 40 through a gap between the surface and the inner wall surface of the opening 4.

The wash water 76 transmitted to the head 40 may be scattered in the circumferential direction of the head 40 as shown in FIG. Furthermore, even if the cleaning water does not scatter in the circumferential direction of the head 40, the cleaning water 78 collected on the outer peripheral surface of the head 40 may droop as shown in FIG.

The temperature is lower than the washed water. Therefore, when the user bathes the scattered cleaning water 76 or the dripping cleaning water 78, the user may feel cold with respect to the cleaning water.

  On the other hand, the water discharge device according to the present embodiment has the rib portion 27 on the lower surface of the buffer chamber 43. Therefore, it is assumed that the cleaning water is transmitted to the outer peripheral surface of the head 40 as indicated by the arrow J or the arrow K shown in FIG. 12 through the gap between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4. In addition, the water discharging device of the present embodiment can suppress the amount of cleaning water that scatters in the circumferential direction of the head 40 and the amount of cleaning water that hangs down. Further, the scattered washing water can be prevented in a wider range than when the rib portion is provided at the tip of the cylindrical body 20 as in the first embodiment or the second embodiment.

Even when the washing water drips, as shown in FIG. 12, the washing water 74 drips substantially along the wall 50, for example, so that the user is less likely to be exposed to the dripping washing water 74.
Thereby, the user can bathe much washing water temporarily stored in the buffer chamber 43 and discharged from the water discharge hole 45. Therefore, there is little possibility that a user will feel cold with respect to washing water. Therefore, the water discharging apparatus of this embodiment can warm a human body etc., without giving a user discomfort.

  In addition, the water discharging apparatus of this invention can be used for the shower apparatus in a bathroom or a shower booth, a toilet bowl with a washing function, etc., for example.
