  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 head 40.

  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. The outer diameter of the large diameter portion 22 is smaller than the inner diameter of the inflow chamber 3, and the large diameter portion 22 is accommodated in the inflow 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.

  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 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 and opens on the reduced diameter portion 21 side. It is possible to flow out from the cylinder 20 to the outside. 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 gas can be guided into the cylindrical body 20 and flow out from the tip of the reduced diameter portion 21.

  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 an 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,
The axial dimension of the opening of the buffer chamber 43 on the side opposite to the thin tube portion 42 is formed so that the other end is larger than the other end. In the buffer chamber 43, the wash water that has flowed out from the tip of the reduced diameter portion 21 can be temporarily stored.

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. As described above, since the axial dimension of the opening of the buffer chamber 43 on the side opposite to the thin tube portion 42 is formed to be larger at the other end than at one end, the water spray plate 44 is disposed with respect to the central axis of the cylindrical body 20. Inclined.
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 formed in a direction perpendicular to the inclination of the water spray plate 44. 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. That is, the inclination direction of the water discharge hole 45 does not match when the water spray plate 44 is rotated 180 degrees around the central axis C1 of the cylindrical body 20 and before it is rotated 180 degrees. ing.

  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. Therefore, the head 40 fixed to the tip of the reduced diameter portion 21 also swings and revolves around the central axis C <b> 2 of the inflow chamber 3 together with the cylindrical body 20.

  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. 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. The washing water rectified in this way in the buffer chamber 43 communicates with the buffer chamber 43 and is discharged outside in the form of a shower from a plurality of water discharge holes 45 on the water spray plate 44 inclined with respect to the central axis C1. . In the present embodiment, since the plurality of water discharge holes 45 are formed perpendicular to the water spray plate 44, the wash water is discharged along the inclination angle of the water spray plate 44 when the water is discharged.

  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. 4, 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 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 spray plate 44 is inclined with respect to the central axis C1, the water discharge flow moves so as to draw a circle larger than the diameter of the water spray plate 44 in which the water discharge holes 45 are formed.

  Here, as a comparative example, when the water spray plate 44 is not inclined with respect to the central axis C1, a water discharge flow having a symmetrical spread with respect to the central axis C1 is discharged, and the cylinder 20 and the head 40 are discharged. Even if it 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 water spray plate 44 inclines with respect to the central axis C1, and the some water discharge hole 45 is formed in the orthogonal | vertical direction with respect to the inclination of the water spray plate 44, it is with respect to the central axis C1. The water discharge flow having an asymmetrical spread is discharged, and the part where the water discharge hits the human body or the like moves around the central axis C1 as the cylinder 20 and the head 40 rotate around the central axis C1. Can be showered over a relatively wide area.

  The expression that each of them is inclined with respect to the central axis of the cylindrical body is not limited to that all the water discharge holes 45 are inclined in the same direction, and at least one water discharge hole 45 is another water discharge hole. A structure inclined in a direction different from 45 is also included. However, if the inclination directions are different among the plurality of water discharge holes 45, the arrival points of the water discharge flow are likely to be dispersed, and it is difficult to obtain a feeling that the water discharge flows uniformly within a certain surface (a feeling of unity of the water discharge flow).

  On the other hand, if all the water discharge holes 45 are formed in a direction perpendicular to the inclination of the water spray plate 44, the water discharge flow from each water discharge hole 45 proceeds along the inclination angle of the water spray plate 44. By optimally setting the inclination angle, the water discharge flow having a uniform in-plane distribution and a sense of unity can be taken without being dispersed, and the portion receiving the water discharge flow can be washed and heated 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.

  Further, in the present embodiment, the swirling revolution of the cylindrical body 20 and the head 40 around the central axis C2 of the inflow chamber 3 forms a water discharge flow that moves in a relatively narrow range as shown by a dotted line in FIG. The The rotation angle determined by the inclination angle of the water spray plate 44 is set to be larger than the revolution angle regulated by the cylindrical 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 rotation rotates in a direction opposite to the moving direction b of the discharged water flow formed by 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 water discharge devices according to the present embodiment, for example, attached to the wall of a bathroom or a shower booth, and if the water discharge from each of the water discharge devices is bathed, the entire body area in a freehand state can be obtained at once. It can be warmed, and a sufficient bathing feeling can be obtained only by the shower 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.
