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

FIG. 1 is a schematic cross-sectional view of a shower device according to an embodiment of the present invention.
The shower device according to the present embodiment mainly includes a guide member 1, a rotating body 20, and a water discharge body 40. The flow of water in the present specification is defined as the water discharge side of the shower device as the downstream and the water supply side from the outside to the shower device as the upstream.

  The guide member 1 has a structure in which a through hole is formed inside the sphere 2. A swirl chamber (accommodating portion) 3 extending in the diameter direction of the sphere 2 is formed inside the sphere 2. An opening 4 that communicates with the inside and the outside of the swirl chamber (accommodating portion) 3 is provided at one end of the swirl chamber (accommodating portion) 3 in the axial direction. The inner diameter dimension of the opening 4 is smaller than the inner diameter dimension of the swirl chamber (accommodating portion) 3, and the opening 4 has its central axis aligned with the central axis of the swirl chamber (accommodating portion) 3. An inflow hole 5 is formed on the outer diameter side of the swirl chamber (accommodating portion) 3 on the other end side in the axial direction. The inflow hole 5 communicates with the inside of the swirl chamber (accommodating portion) 3 and the outside of the spherical body portion 2. The water guided from the outside of the guide member 1 to the inflow hole 5 flows into the swirl chamber (accommodating portion) 3 from the tangential direction via the inflow hole 5, so The swirling flow is formed. The opening 4 is open to the outside of the guide member 1, and the opening on the other end side of the swirl chamber (accommodating portion) 3 is closed by a sealing member 6.

  The rotating body 20 is formed in a substantially bottle shape having a reduced diameter portion 21 and a large diameter portion 22. The distal end side of the reduced diameter portion 21 serves as a connecting portion 25 to which a connecting portion formed at the inlet 42 in the water discharge body upstream of the water discharge body 40 is connected. The outer diameter dimension of the large diameter portion 22 is smaller than the inner diameter dimension of the swirl chamber (accommodating portion) 3, and the large diameter portion 22 is accommodated inside the swirl chamber (accommodating portion) 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. Since the outer diameter of the large-diameter portion 22 is larger than the inner diameter of the opening 4, the entire rotating body 20 protrudes from the guide member 1 as long as the guide member 1 is closed by the sealing member 6. There is no.

  As shown in FIG. 1, in the state where the rotating body 20 and the swirl chamber (accommodating portion) 3 are aligned with each other, the gap between the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening portion 4. Furthermore, a gap is also formed between the outer peripheral surface of the large-diameter portion 22 of the rotating body 20 and the inner wall surface of the swirl chamber (accommodating portion) 3. The rotating body 20 is not fixed with respect to the guide member 1 and can swing and revolve freely to rotate and swing.

  Both ends of the rotating body 20 in the axial direction are opened, and the water that has flowed into the rotating body 20 from the opening 24 on the large diameter portion 22 side flows in the axial direction inside the rotating body 20 and from the opening on the reduced diameter portion 21 side. It can flow out of the rotating 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 peripheral surface (side surface) of the large-diameter portion 22 of the rotating body 20 and flow into the swirl chamber (accommodating portion) 3. The water thus introduced can be guided to the inside of the rotating body 20 through the through holes 23 and can flow out from the tip of the reduced diameter portion 21.

  The water spouting body 40 is formed in a flat shape having a larger dimension in the radial direction than the rotating body 20, and the center in the radial direction is made to coincide with the central axis C <b> 1 of the rotating body 20. The water spouting body 40 includes an inlet 42 in the water spouting body whose area is larger than the outer diameter cross-sectional area of the distal end portion of the reduced diameter portion 21, a funnel-shaped storage chamber member 41, and a water spray plate 44. The tip of the reduced diameter portion 21 of the rotator 20 is fitted and fixed inside the inflow port 42 in the water spouting body, so that the rotator 20 and the water spouting body 40 rotate and swing together. Revolve.

  A speed reduction part (reservoir chamber) 43 is formed inside the water spouting body 40, and the opening at the tip of the reduced diameter part 21 of the rotating body 20 faces the speed reduction part (reservoir chamber) 43. The radial dimension of the speed reduction part (reservoir chamber) 43 is larger than the radial dimension of the rotating body 20, and the water flowing out from the tip of the reduced diameter part 21 can be temporarily stored in the speed reduction part (reservoir chamber) 43. Yes.

  The water spray plate 44 is provided in a lid shape that closes the opening opposite to the inlet 42 in the water spouting body in the speed reduction portion (reservoir chamber) 43. The water spray plate 44 is formed in a disk shape having a radial dimension larger than that of the rotating body 20, and the water spray plate 44 has a plurality of water discharge ports 45 penetrating in the thickness direction. One end of the water discharge port 45 communicates with the speed reducing portion (storage chamber) 43, and the other end faces the outside of the water discharge body 40.

  The plurality of water outlets 45 are formed along the circumferential direction at least on the outer peripheral side portion of the water spray plate 44. Each spout 45 has an axial direction that is not parallel to the central axis C <b> 1 of the rotating body 20 but is inclined. In the present embodiment, all the water discharge ports 45 are inclined in the same direction. Accordingly, each water discharge port 45 is inclined in an asymmetric relationship with respect to the central axis C <b> 1 of the rotating body 20. That is, the direction in which the water discharge port 45 is inclined when the water spray plate 44 is rotated (rotated) by 180 degrees around the central axis C1 around the central axis C1 of the rotating body 20 and before it is rotated (rotated) by 180 degrees. Are inconsistent.

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

  FIG. 2 is a schematic view of the swirl chamber (accommodating portion) 3 and the rotating body 20 (the large-diameter portion 22) accommodated therein as seen from the plane direction, corresponding to the AA-AA cross section in FIG. To do.

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

  The rotating body 20 (the large-diameter portion 22) housed inside the swirl chamber (accommodating portion) 3 receives the force of the swirling flow, and thus the center of the swirl chamber (accommodating portion) 3 as shown in FIG. While tilting with respect to the axis C2, for example, it revolves around the central axis C2 of the swirl chamber (accommodating portion) 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 rotating body 20 contacts the opening 4, and a part of the side surface (circumferential surface) of the large diameter portion 22 is a guide for the swirl chamber (accommodating portion) 3. By contacting the surface 3 a, the inclination of the rotating body 20 with respect to the central axis C <b> 2 of the swirl chamber (accommodating portion) 3 is restricted.

  In this specification, when the rotating body 20 revolves around the central axis C2 while being inclined with respect to the central axis C2 of the swirl chamber (accommodating portion) 3, it is referred to as “swing swing”. That is, when the rotating body 20 revolves around the central axis C2 while tilting with respect to the central axis C2 of the swirl chamber (accommodating section) 3, the rotating body 20 is located in the vicinity of the portion where the reduced diameter portion 21 contacts the opening 4. It swings so that the tip of the reduced diameter portion 21 swings its head around the center. Accordingly, the water discharge body 40 fixed to the tip of the reduced diameter portion 21 also swings and revolves around the central axis C <b> 2 of the swirling chamber (accommodating portion) 3 together with the rotating body 20. In this embodiment, the inflow hole 5 that creates a swirling flow in the swirling chamber (accommodating portion) 3 is a drive mechanism.

  When the rotating body 20 swings and revolves, a part of the outer peripheral surface of the reduced diameter portion 21 contacts the inner wall surface of the opening 4 and a part of the side surface (peripheral surface) of the large diameter portion 22 is a swirl chamber. Since it is in contact with the guide surface 3 a of the (accommodating portion) 3, the dynamic friction force generated at these contact portions acts on the rotating body 20. By this dynamic friction force, the rotating body 20 does not slide and move in the swirl chamber (accommodating portion) 3 in a state where it is in contact without changing the contact portion with the opening 4 or the guide surface 3a. Swing and revolve while rolling the inner wall surface of 4 and the guide surface 3a. The fact that the rotating body 20 rolls on the inner wall surface of the opening 4 or the guide surface 3a means that the rotating body 20 rotates around its own central axis C1.

  That is, the rotating body 20 swings and revolves around the central axis C <b> 2 of the swirl chamber (accommodating portion) 3 while rotating about its own central axis C <b> 1. The revolution direction (the direction of arrow A in FIG. 2) of the rotating body 20 around the central axis C2 of the swirl chamber (accommodating portion) 3 is the same direction as the swirl direction of the swirl flow formed in the swirl chamber (accommodating portion) 3. In addition, the direction of rotation around the central axis C1 of the rotating body 20 (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 rotating body 20, the inflow speed from the inflow hole 5, the swirl chamber (accommodating portion) 3 and the large-diameter portion 22 The rotation direction and the number of rotations can be controlled by a gap of

  Part of the water that has flowed into the swirl chamber (accommodating portion) 3 flows into the inside of the rotating body 20 from the opening 24 at the end on the large diameter portion 22 side of the rotating body 20 and the through hole 23 formed in the side surface. The axial direction of the rotating body 20 flows toward the tip of the reduced diameter portion 21. And the water which flowed out from the front-end | tip of the diameter reducing part 21 flows in into the deceleration part (reservoir chamber) 43 inside the water discharging body 40. FIG. When water in the swirl chamber (accommodating portion) 3 flows into the rotating body 20 and flows through the rotating body 20, it still has a swirling component. Further, when flowing through a relatively narrow flow path called the reduced diameter portion 21, the flow velocity becomes faster.

Since the deceleration part (storage chamber) 43 is formed in the space in the flat storage chamber member 41 having a larger radial dimension than the swirl chamber (accommodating part) 3 and the rotating body 20, the cross-sectional area of the connecting part Further, the area is enlarged, and the momentum of water flowing from the tip of the reduced diameter portion 21 can be reduced. Further, the momentum of water flowing from the tip of the reduced diameter portion 21 is reduced by making the cross-sectional area of the connecting portion 25 smaller than the cross-sectional area of the inlet 42 in the water discharge body upstream of the speed reducing portion (reservoir chamber) 43. Can be reliably reduced. That is, only by temporarily storing water in the speed reduction part (storage chamber) 43 without adding a special mechanism or parts, the flow rate of water can be greatly reduced, and the swirling component can be lost. .
In this way, the water rectified in the speed reduction part (storage chamber) 43 is discharged to the outside in a shower form from a plurality of water discharge ports 45 communicating with the speed reduction part (storage chamber) 43. Furthermore, since the plurality of water discharge ports 45 have a total cross-sectional area smaller than that of the speed reduction part (reservoir chamber) 43, the water is decelerated by the speed reduction part (reservoir chamber) 43 and accelerates the water whose swirl component is lost. Water can be discharged. Furthermore, since the water discharge port 45 is inclined with respect to the central axis C <b> 1 of the rotating body 20, water having no swirl component can be discharged in the inclined direction.

  As described above, the rotating body 20 and the water spouting body 40 move in combination with swinging revolution and rotation, and therefore, the water discharge trajectory of the shower-like water discharge flow obtained by the shower device according to the present embodiment (for example, with respect to a human body or the like). The movement locus on the surface of the human body of the collision part of the water discharge 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. 4, the shower device shows only the rotating body 20 and the water discharge body 40 which are movable parts, and the guide member 1 in which the swirl chamber (accommodating portion) 3 is formed is not shown.

  Due to the rotation of the rotating body 20 and the water discharge body 40 around the central axis C1 thereof, the rotating body 20 and the water discharge body 40 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 discharge flow is formed. Here, since the water discharge port 45 is inclined with respect to the central axis C <b> 1 of the rotating body 20, the water discharge flow moves so as to draw a circle larger than the diameter of the water spray plate 44 on which the water discharge port 45 is formed.

  Here, as a comparative example, when a plurality of water outlets 45 are inclined in a symmetrical relationship with respect to the central axis C1, or when all the water outlets 45 are parallel to the central axis C1 of the rotator 20, the central axis Even if the water discharge flow having a symmetrical spread with respect to C1 is discharged, and the rotating body 20 and the water discharge body 40 rotate around the central axis C1, the water discharge flow 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 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 and rotated. As the body 20 and the water spouting body 40 rotate around the central axis C1, a portion where the water discharge hits the human body or the like moves around the central axis C1, and the water discharge can be exposed to a relatively wide range.

  The expression that the plurality of water discharge ports 45 are inclined in an asymmetric relationship with respect to the central axis C1 is not limited to the fact that all the water discharge ports 45 are inclined in the same direction, and at least one water discharge hole 45 is provided. The structure inclined in the direction different from the other spout 45 is also included. However, if the inclination directions are different among the plurality of water discharge ports 45, the arrival points of the water discharge flow are easily dispersed, and it is difficult to obtain a feeling that the water discharge flow is uniformly applied within a certain surface (a feeling of unity of the water discharge flow).

  On the other hand, if all the spouts 45 are inclined in the same direction, the spout flow from each spout 45 proceeds in the same direction, so that the in-plane distribution is uniform and has a sense of unity without being dispersed. The water discharge can be bathed, and the portion that receives the water discharge can be washed and warmed evenly. Further, suppressing the dispersion of the water discharge flow also suppresses the heat of the water discharge flow from escaping into the air, thereby suppressing the temperature drop during the flight of the water discharge flow.

  The water that has flowed into the swirl chamber (accommodating section) 3 not only rotates to rotate and rotate the rotator 20 and swing, but the water itself passes through the rotator 20 and the water discharge body 40 to discharge water. It becomes a discharged water flow discharged from 45. Here, if the water reaches the water outlet 45 with a swirling component, the water is dispersed and discharged in directions other than the inclination direction of the water outlet 45, and the in-plane distribution is not sensed as a unity. It tends to be a water discharge.

  Therefore, in the present embodiment, a speed reduction unit (reservoir chamber) 43 is provided between the rotating body 20 and the water spray plate 44, and water is temporarily stored in the speed reduction unit (reservoir chamber) 43, whereby the flow rate of water is increased. Can be greatly reduced, and the swirl component can be lost. The water passing through the spout 45 loses the swirling component, so that the spout 45 can be reliably discharged in the inclined direction, the dispersion of the spout flow is suppressed, and the in-plane distribution is uniform and a sense of unity. Is obtained.

  For example, if the water discharge port 45 is formed near the center of the water spray plate 44, the water flowing out from the tip of the rotating body 20 does not receive a sufficient rectifying action in the speed reduction part (reservoir chamber) 43 and has a swirling component. There is a concern that the water will flow into the spout 45 as it is. Therefore, it is desirable to form the water outlet 45 in the outer peripheral side portion of the water spray plate 44 as much as possible. Moreover, when the water discharge port 45 is formed in the outer peripheral side part of the water spray plate 44, the water discharge flow can be discharged in a wider range by the centrifugal force generated by the above-described rotation and swing revolution.

  Further, in the present embodiment, the rotating body 20 and the water spouting body 40 move in a relatively narrow range as shown by a dotted line in FIG. 4 by swinging and revolving around the central axis C2 of the swirling chamber (accommodating portion) 3. A water discharge flow is formed. The rotation angle determined by the inclination of the water discharge port 45 is set to be larger than the revolution angle regulated by the rotating body 20 and the guide surface 3a, whereby the water discharge flow formed by this swing revolution is A range narrower than the moving range of the discharged water flow formed by the rotation moves in the direction a opposite to the moving direction b of the discharged water flow formed by the rotation at a higher speed than the movement in the b direction. Therefore, as a whole, the discharged water flow moves in a relatively narrow range at a high speed in the direction of arrow a in FIG. 4 and slowly moves in a range larger than the moving range in the b direction opposite to the a direction.

  The water discharge flow formed by swinging and revolving can cover the inner area that cannot be covered by the water discharge flow formed by rotation alone. Can be obtained. Thus, according to this embodiment, it is possible to realize a shower-like water discharge flow that covers a wider area in a planar shape without hollowing out. A plurality of such shower devices according to the present embodiment, for example, attached to the wall of a bathroom or a shower booth, and showered with water discharged from each of these shower devices, the entire body in a freehand state without unevenness at once. It can be warmed, and a sufficient bathing feeling can be obtained only by the water discharge flow. Unlike bathing in a bathtub, such a shower bath is safe for small children and the elderly, especially without feeling the pressure of water pressure on the body (burden on the cardiopulmonary) or drowning.

When swinging and revolving the rotating body 20 and the water spouting body 40, the rotating body 20 and the water spouting body 40 swing (oscillate) around the contact portion between the reduced diameter portion 21 and the opening 4. In this case, in order to reduce the moment of inertia and make the swinging (swinging) of the rotating body 20 and the water spouting body 40 efficiently and reliably, the center of gravity when the rotating body 20 and the water spouting body 40 are considered as one body. However, it is desirable that it is in the vicinity of the contact portion between the reduced diameter portion 21 and the opening portion 4 which is the center of swinging (swinging). Further, the rotating body 20 rotates by dynamic friction caused by the centrifugal force of swinging (revolution). Therefore, it is desirable that the center of gravity when the rotator 20 and the water discharger 40 are considered as one body is in the air outside the opening 4 that is not easily affected by buoyancy. Thereby, it becomes easy to rotate with a small flow rate, and a comfortable water discharge flow can be bathed with a small flow rate.
Further, the water spouting body 40 is formed in a flat shape in order to discharge water in a wider range, and the rotating body 20 is formed long in the direction of the central axis C1 in order to receive the swirl force.

  Further, in order to perform rotation when the rotating body 20 is tilted, at least the outer peripheral surface of the reduced diameter portion 21 and the inner wall surface of the opening 4 need to contact each other, but in order to perform rotation more reliably. The large-diameter portion 22 is also in contact with the inner wall surface (guide surface 3a) of the swirl chamber (accommodating portion) 3 so that the frictional force of the contact portion between the rotating body 20 and the guide member 1 is increased. desirable.

  FIG. 5 is a schematic cross-sectional view of a shower device according to an embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same component as one Embodiment of this invention 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 it is possible to adjust the water discharge direction of the water discharge flow discharged from the water discharge port 45 formed in the water spray plate 44. Become.

  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. In the inflow hole 54 formed in the sealing member 6, the downstream side leading to the swirl chamber (accommodating portion) 3 is inclined with respect to the central axis of the swirl chamber (accommodating portion) 3, and thus passed through the inflow hole 54. Water flows from the tangential direction into the swirl chamber (accommodating portion) 3 and turns into the swirl chamber (accommodating portion) 3.

  In the present embodiment, a buffer plate 61 (rectifying mechanism) is provided on the back side of the water spray plate 44 in the speed reduction portion (storage chamber) 43 so as to be separated from the water spray plate 44. That is, a gap is formed between the water spray plate 44 and the buffer plate 61. A through hole 62 is formed in the buffer plate 61 corresponding to the water outlet 45 formed in the water spray plate 44. Each through hole 62 has its opening position substantially coincided with the upstream side of the water discharge port 45. The axial direction of the through hole 62 is not inclined and is substantially parallel to the central axis of the rotating body 20.

  The water that has flowed into the speed reduction unit (reservoir chamber) 43 from the tip of the rotating body 20 passes through the through hole 62 formed in the buffer plate 61 before reaching the water discharge port 45. For this reason, it has a structure in which the resistance for water flowing out from the tip of the rotator 20 toward the water outlet 45 is increased, and even when the flow rate is large, the swirl component is lost, and the water outlet 45 Water can be discharged neatly and smoothly along the tilt direction. That is, the rectifying mechanism unit has a function of blocking the flow of water having the swirl component that has flowed into the speed reduction unit and losing the swirl component.

FIG. 6 is a schematic cross-sectional view of a shower device according to an embodiment of the present invention.
In the present embodiment, a convex annular wall 301 (rectifying mechanism portion) extending to the upstream side of water is provided on the back side of the water spray plate 44 in the speed reduction portion (storage chamber) 43. Further, the outer wall 51 of the annular wall 301 is provided smaller in the circumferential direction than the arrangement of the water outlet 45. Further, the axial direction of the annular wall 301 is not inclined and is substantially parallel to the central axis of the rotating body 20.

  The water that has flowed into the speed reduction unit (reservoir chamber) 43 from the tip of the rotating body 20 passes through the inside of the annular wall 301 before reaching the water discharge port 45. For this reason, the water that flows out from the tip of the rotating body 20 and travels toward the spout 45 is directed to the spout 45 after receiving the resistance of the annular wall 301. Therefore, even when the flow rate is particularly high, the swirl component can be lost and water can be discharged neatly and without any disturbance along the inclination direction of the water discharge port 45.

FIG. 7 is a schematic cross-sectional view of a shower device according to an embodiment of the present invention.
In the present embodiment, a recessed portion 302 (rectifying mechanism portion) that is recessed on the downstream side of water is provided on the back side of the water spray plate 44 in the deceleration portion (reservoir chamber) 43. Further, the inner wall 52 of the concave portion 302 is provided smaller in the circumferential direction than the arrangement of the water discharge port 45. Further, the axial direction of the concave portion 302 is not inclined and is substantially parallel to the central axis of the rotating body 20.
The water that has flowed into the speed reduction portion (reservoir chamber) 43 from the tip of the rotating body 20 passes through the inside of the concave portion 302 before reaching the water discharge port 45. For this reason, the water which flows out from the front-end | tip of the rotary body 20 and goes to the water discharge port 45 goes to the water discharge port 45, after receiving resistance inside a concave part. Therefore, even when the flow rate is particularly high, the swirl component can be lost and water can be discharged neatly and without any disturbance along the inclination direction of the water discharge port 45.

FIG. 8 is a schematic diagram illustrating a rotating body included in the shower device according to the embodiment of the present invention. FIG. 8A is a schematic side view of the rotating body of the shower device according to the embodiment of the present invention as viewed from the side, and FIG. 8B shows the rotating body in FIG. It is the plane schematic diagram seen in the direction of arrow X, and the plane schematic diagram of a modification.

  In the present embodiment, the same effect can be obtained even if a rectifying mechanism is provided in the flow path of the rotating body 20 on the upstream side of the end of the connecting portion without providing the rectifying mechanism in the speed reducing portion (storage chamber) 43. It is done. The rectifying mechanism portion in the flow path of the rotator 20 upstream from the tip of the connecting portion is provided with a slit-like plate 303 in the flow path. The slit-like plate 303 is provided so as to extend from the wall surface of the flow path of the rotating body 20.

  The water flowing into the rotating body 20 flows into the revolving rotating body and has a swirling component. Further, water having a swirl component passes through a slit-like plate 303 provided in the flow path of the rotating body 20 having a small diameter. For this reason, the water that flows out from the tip of the connecting portion and travels toward the spout 45 passes through the speed reduction portion (reservoir chamber) 43 in a state where the swirl component is lost due to the resistance of the slit-shaped plate 303, and the spout is discharged. Head to the water mouth 45. Therefore, even when the flow rate is particularly high, the swirl component can be lost, and the water can be discharged cleanly and undisturbed along the inclination direction of the water discharge port 45. Further, as shown in the modified example of FIG. 8B, the slit-like plate 303 has the same effect even if it is arranged in a plurality or in a crossing manner.

Next, an embodiment of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same component as embodiment mentioned above, and the detailed description is abbreviate | omitted.
FIG. 1 is a schematic view illustrating a shower device according to an embodiment of the invention.
FIG. 9 is a schematic diagram illustrating a rotating body included in the shower device according to the present embodiment. 10A is a schematic side view of the rotating body of the shower device according to the present embodiment as viewed from the side, and FIG. 10B is a view of the cylindrical body in FIG. It is the plane schematic diagram looked at in the direction.

  The shower device according to the present embodiment directly applies energy that causes the swing and revolution and rotation of the rotating body from the fluid (water) to the rotating body. The water flows into the inside of the guide member 101 through the inflow hole 109 formed in the sealing member 106 and into the rotating chamber (accommodating portion) 103 formed in a cylindrical shape into which water flows. Therefore, the inflow hole 5 is not formed in the rotation chamber (accommodating portion) 103 unlike the swirl chamber (accommodating portion) 3 shown in FIG. The inflow hole 109 is connected to the center of the rotation chamber (accommodating portion) 103. The passage sectional area of the inflow hole 109 is smaller than the passage sectional area of the passage 108 that guides the fluid to the rotating chamber (accommodating portion) 103. Therefore, the flow velocity of the water flowing into the rotation chamber (accommodating portion) 103 can be increased.

  As shown in FIG. 10, the rotating body 120 included in the shower device according to the present embodiment is formed in a substantially bottle shape having a reduced diameter portion 21 and a large diameter portion 22 like the rotating body 20 shown in FIG. 1. Has been. The large diameter portion 22 side of the rotating body 120 is not opened. Therefore, in the present embodiment, the water that has flowed into the rotating chamber (accommodating portion) 103 can be guided to the inside of the rotating body 120 through the through hole 23 and flow out from the tip of the reduced diameter portion 21.

  And the water which flowed out from the front-end | tip of the diameter reducing part 21 flows in into the deceleration part (reservoir chamber) 43 inside the water discharging body 40. FIG. Since the speed reduction part (storage chamber) 43 is a flat space having a larger radial dimension than the rotation chamber (accommodation part) 103 and the rotating body 120, the area is larger than the cross-sectional area of the connection part. The momentum of water flowing from the tip of the reduced diameter portion 21 can be reduced. That is, only by temporarily storing water in the speed reduction part (storage chamber) 43 without adding a special mechanism or parts, the flow rate of water can be greatly reduced, and the swirling component can be lost. . In this way, the water rectified in the speed reduction part (storage chamber) 43 is discharged to the outside in a shower form from a plurality of water discharge holes 45 communicating with the speed reduction part (storage room) 43. Furthermore, since the plurality of water discharge ports 45 have a total cross-sectional area smaller than that of the speed reduction part (reservoir chamber) 43, the water is decelerated by the speed reduction part (reservoir chamber) 43 and accelerates the water whose swirl component is lost. Water can be discharged. Furthermore, since the water discharge port 45 is inclined with respect to the central axis C <b> 1 of the rotating body 20, water having no swirl component can be discharged in the inclined direction.

  The rotating body 120 has an axial flow blade 122 at the lower end of the large diameter portion 22. This axial flow blade 122 directly receives the flow of water that has entered the rotating chamber (accommodating portion) 103 from the inflow hole 109 and converts this into driving force of the rotating body 120. Since water enters the rotary chamber (accommodating portion) 103 from the small diameter inflow hole 109, it hits the axial flow blade 122 at a high flow rate. Therefore, the rotating body 120 revolves under a large driving force, and rotates around the central axis C <b> 1 of the rotating body 120 itself by the frictional force generated in the rotating body 120. A structure composed of an inflow hole 109 for guiding water into the rotating chamber (accommodating section) 103 and an axial flow blade 122 provided in the rotating body 120 is called a drive mechanism. In addition, about another structure, it is the same as that of the structure of the shower apparatus mentioned regarding FIGS. 1-4.

  The behavior of the rotating body 120 will be described in more detail. When water is supplied from the inflow hole 109 to the rotating chamber (accommodating portion) 103, the internal pressure of the rotating chamber (accommodating portion) 103 increases, and a part of the outer peripheral surface of the reduced diameter portion 21 is pressed against the inner wall surface of the opening 4. In addition, a part of the side surface (circumferential surface) of the large diameter portion 22 is pressed against the guide surface 103 a of the rotating chamber (accommodating portion) 103. The axial flow blade 122 changes the flow of water to the rotating chamber (accommodating portion) 103 into a driving force, so that the rotating body 120 receives the driving force and the rotating body 120 is the center of the rotating chamber (accommodating portion) 103. Oscillate and revolve around axis C2. When such a revolving motion occurs, a frictional force is generated at a contact portion between the reduced diameter portion 21 and the opening 4 and a contact portion between the large diameter portion 22 and the rotating chamber (accommodating portion) 103. The rotating body 120 starts rotating around the central axis C <b> 1 of the rotating body 120 in the rotating chamber (accommodating portion) 103.

  Even when the axial flow blade 122 is not a swirling flow but changes the flow of water to the rotation chamber (accommodating portion) 103 into a driving force as in the shower device according to the present embodiment, it is formed by swinging revolution. The water discharge flow can cover the inner area that cannot be covered by the water discharge flow formed by the rotation alone, and the water discharge flow does not go out so as to obtain a non-uniform surface discharge water flow. be able to. Thus, also in this embodiment, it is possible to realize a shower-like water discharge flow that covers a wider area in a planar shape without hollowing out. Further, since the plurality of water discharge ports 45 are inclined in an asymmetric relationship with respect to the central axis C1, as described above with reference to FIG. 3, a water discharge flow having an asymmetrical spread with respect to the central axis C1 is discharged. As the rotating body 120 and the water spouting body 40 rotate around the central axis C1, the portion where the water discharge hits the human body or the like moves around the central axis C1, and the water discharging flow can be exposed to a relatively wide range. .

FIG. 11 is a schematic view illustrating a shower device according to an embodiment of the invention.
The shower apparatus concerning this embodiment raise | generates the swing revolution and rotation of a rotary body by driving a water wheel and a gearwheel with a water flow. Therefore, the shower device according to the present embodiment directly applies energy that causes the swinging revolution and rotation of the rotating body from the fluid (water) to the rotating body. In the shower device according to the present embodiment, a rotating chamber (accommodating portion) 203 formed in a cylindrical shape into which water flows is formed inside the guide member 201. Water flows into the rotating chamber (accommodating portion) 203 through an inflow hole 205 formed in the rotating chamber (accommodating portion) 203. The inflow hole 205 may be formed to be inclined like the inflow hole 5 shown in FIG.

It is formed into a shape. The large diameter portion 22 side of the rotating body 170 is not opened. Therefore, in the present embodiment, the water that has flowed into the rotating chamber (accommodating portion) 203 can be guided to the inside of the rotating body 170 through the through hole 23 and flow out from the tip of the reduced diameter portion 21.
An impeller 163 is rotatably provided around the central axis C2 of the rotating chamber (accommodating portion) 203 below the rotating chamber (accommodating portion) 203 (upper portion of the sealing member 156). It is directly rotated by the flow of water that has entered the rotation chamber (accommodating portion) 203 from the hole 205. The impeller 163 is provided with a gear 164 that is rotatable about the central axis C <b> 2 via a shaft 163 a, and the gear 164 is driven in synchronization with the rotational drive of the impeller 163. The gear 164 is configured to mesh with gear teeth 165 provided at the lower end of the large diameter portion 22 of the rotating body 170.

  The rotating body 170 is engaged by a gear 164 provided at the lower portion of the rotating chamber (accommodating portion) 203 and a gear tooth 165 provided at the lower end of the large-diameter portion 22 of the rotating body 170. The impeller 163 receives and drives the flow of water that has entered the rotating chamber (accommodating portion) 203 from the rear. Thus, when the impeller 163 rotates, the rotation around the central axis C2 is transmitted to the rotating body 170 by being eccentric from the central axis C2 of the rotating chamber (accommodating portion) 203. At this time, since the rotating body 170 is tilted from the central axis C2 at a predetermined tilt angle, it revolves in a swinging manner at the predetermined tilt angle.

  When such swinging revolution occurs, the rotating body 170 rotates about the central axis C <b> 1 of the rotating body 170 due to the meshing between the gear teeth 165 and the gear 164. Therefore, the shower apparatus according to the present embodiment causes the rotating body 170 to swing around the central axis C2 while rotating around the central axis C1 of the rotating body 170 itself, thereby causing water to flow out from the tip of the reduced diameter portion 21. Can do. An inflow hole 205 that guides water into the rotating chamber (accommodating portion) 203, an impeller 163 provided in the rotating chamber (accommodating portion) 203, a gear 164 connected to the impeller 163, and a gear 164 What is constituted by the gear teeth 165 provided on the rotating body 170 so as to engage with each other is referred to as a drive mechanism. In addition, about another structure, it is the same as that of the structure of the shower apparatus mentioned regarding FIGS. 1-4.

  Like the shower apparatus according to the present embodiment, the driving force of the impeller 163 that directly receives the flow of water that has entered the rotation chamber (accommodating portion) 203 from the inflow hole 205 is transmitted via the gear 164 instead of the swirling flow. Thus, even when the swinging revolution and rotation of the rotating body 170 occur, as described above with reference to FIGS. 9 and 10, only the discharged water flow formed by the rotation by the discharged water flow formed by the swinging revolution. Then, it is possible to cover a more inner range that cannot be covered, so that the water discharge flow is not so-called, and a flat water discharge flow without unevenness can be obtained. Further, since the plurality of water discharge ports 45 are inclined in an asymmetric relationship with respect to the central axis C1, the same effects as those described above with reference to FIGS. 9 and 10 can be obtained.

Therefore, the shower device according to the present embodiment directly applies energy that causes the swinging revolution and rotation of the rotating body from the fluid (water) to the rotating body. In the shower device according to the present embodiment, a rotating chamber (accommodating portion) 203 formed in a cylindrical shape into which water flows is formed inside the guide member 201. Water flows into the rotating chamber (accommodating portion) 203 through an inflow hole 205 formed in the rotating chamber (accommodating portion) 203. The inflow hole 205 may be formed to be inclined like the inflow hole 5 shown in FIG.

The transmission disk 225 is driven by the impeller 263 receiving the flow of water that has entered the rotation chamber (accommodating portion) 203 from the inflow hole 205. Thus, when the impeller 263 rotates, the rotation around the central axis C2 is transmitted to the rotating body 220 by being eccentric from the central axis C2 of the rotation chamber (accommodating portion) 203. At this time, since the rotating body 220 is inclined from the central axis C2 at a predetermined inclination angle, it revolves in a swinging manner at the predetermined inclination angle. When such swinging revolution occurs, the rotating body 220 receives a large driving force, and the central axis of the rotating body 220 itself due to the frictional force generated at the contact portion between the rotating body 220 and the guide member 201. Rotate around C1.
