[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cleaning nozzle that performs cleaning by discharging cleaning water.
[0002]
[Prior art]
Conventionally, a swirl chamber to which cleaning water is supplied along a circumferential surface of a chamber formed in a cylindrical shape, one end protrudes from a through hole of the swirl chamber, and the other end can freely rotate in the swirl chamber. A cleaning nozzle having a swirling member provided with a water discharge channel, wherein the swirling member swirls by a force directly received from the kinetic energy of the cleaning water supplied to the swirl chamber, and lift and centrifugal force generated by the kinetic energy The technique for inclining the swivel member from the central axis of rotation and starting the swing is inclined by the force directly received from the kinetic energy of the washing water and the lift and centrifugal force generated by the kinetic energy.
Lift refers to the pressure difference that occurs because the flow rate of the wash water is not uniform near the swivel member.
In addition, as a technique for inclining the swivel member from the central axis of rotation and starting the swing, there is a technique in which a main body support portion is provided at the lower end of the swivel member and the swivel member is forcibly inclined from the central axis of rotation. .
[0003]
[Problems to be solved by the invention]
However, in the technology of starting the swing by tilting the swirling member directly from the kinetic energy of the washing water and the lift and centrifugal force generated by the kinetic energy, the swirling member is surrounded by the swirl chamber through the through hole. It is pressed against the sliding part which is a contact part with the center part of the swirl chamber, and is fixed by the force in the direction of water discharge at the central part on the central axis of the swirl chamber. In order to swing the swivel member in a state where the swivel member is pressed against the sliding portion that is a contact portion with the periphery of the through hole of the swirl chamber due to the pressure in the swirl chamber, A force directly received from the kinetic energy of the washing water, which is more eccentric, and a lift force and a centrifugal force generated by the kinetic energy are necessary, and there is a possibility that the oscillation does not occur reliably depending on conditions.
[0004]
  Specifically, referring to the drawings, conventionally, as shown in FIG. 26, the swiveling member 102 is pressed against the sliding portion 109 with the cleaning nozzle 101 by the force F1 by the pressure P in the swirling chamber 105. Further, the force directly received from the kinetic energy of the washing water and the lift and centrifugal force F2 generated by the kinetic energy also affect the swivel member 102. This is schematically depicted in FIG.
  In FIG. 27, forces F1 and F2 are applied to the object 111, and the point Q is fixed to the plane 112.
  This thingPoints of the body 111 shown in FIG.Rotation around QFigure 26Conditions where the turning member 102 is eccentric from the center of the swirl chamber 105Is the point in FIG.F2 × A−F1 × B / 2> 0 when the clockwise direction is positive from the balance of rotational moments around Q.. Here, as shown in FIG.Working in the middleLet's say. ThenThe greater the distance B, the greater the force F2 that moves the object.
  In FIG. 26, even in the technique in which the contact portion 108 of the swivel member 102 with the cleaning nozzle 108 is conventionally provided with a sliding surface, the contact portion 109 of the swivel member and the cleaning nozzle is in contact with a plane and a curve. Depending on the processing accuracy of the R portion, the contact portion 109 may be close to the contact between the flat surfaces.
  for that reasonIn FIG.The force that is directly received from the kinetic energy of washing water and the lift and centrifugal force generated by the kinetic energyIs the object 111 (the rotation of FIG.Rotating member 102)There was a possibility that it would not swing.
  In addition, once cleaning water is passed and the swirling chamber is full, when the cleaning water is started again, pressure propagation in the swirling chamber is directly affected by the kinetic energy of the cleaning water due to the viscosity of the cleaning water. Since the swivel member is affected more quickly than the lift force and centrifugal force generated by the force and the kinetic energy, it is impossible to expect the eccentricity of the swivel member in the initial stage, and it is difficult to reliably start the swing.
[0005]
In addition, the main body support portion is provided at the lower end of the swivel member, and the technique for forcibly tilting the swivel member from the central axis of rotation, tilting the swivel member from the central axis of rotation, and starting swinging is the lower end of the swivel member. The tilt angle from the central axis of rotation of the swivel member is completely regulated by the main body support portion provided on the main body support portion, and the swinging rotational speed decreases due to the sliding resistance in the main body support portion. There was a possibility that could not be started.
[0006]
In addition, the present invention has been made to solve the above-described problem, and a swirl chamber to which cleaning water is supplied along a circumferential surface of a chamber formed in a cylindrical shape, and one end from a through hole of the swirl chamber. And a swirling member provided with a water discharge channel whose other end is freely rotatable in the swirl chamber, and a force directly received from the kinetic energy of the washing water supplied to the swirl chamber and the motion In the cleaning nozzle in which the swivel member swivels due to the lift and centrifugal force generated by energy, it can be easily produced, and it was realized that the swinging of the swivel member was started reliably and the sliding resistance of the swivel member was reduced. A cleaning nozzle is provided.
[0007]
[Means for solving the problems and actions / effects]
[0008]
  The cleaning nozzle of the present invention made to achieve the above object is
  A swirl chamber in which cleaning water is supplied along the circumferential surface of the cylindrically formed room;
  Through this swirl chamberOne end with a smaller diameter than the hole is turned from the through hole.Projecting outside the chamberOther than a diameter larger than the through holeA swirl member disposed in the swirl chamber such that an end thereof is positioned in the swirl chamber, provided with a water discharge passage for the wash water, and for discharging the wash water from the water discharge passage;
  In the washing nozzle that swirls the swivel member by the force directly received from the kinetic energy of the washing water supplied to the swirl chamber and the lift and centrifugal force generated by the kinetic energy,
  The swivel member is movable in the axial direction of the swivel member central axis.The shaft during the swiveling accompanying the supply of cleaning water to the swirling chamberMove in the line directionWhen the swirl chamber member central axis is inclined with respect to the swirl chamber central axis, the small-diameter swivel member portion protruding from the through hole and the large-diameter swivel portion located in the swirl chamber are swung. Front of the connection with the member partPoint contact around the through holeTouchIn addition, the swirl chamber member central axis is swiveled by causing the swing chamber member central axis to swing with respect to the swirl chamber central axis.
  In the present invention, the point contact between the swivel member and the periphery of the through hole refers to contact between acute angles or between an acute angle and a plane.
  With such a configuration, when the cleaning water is supplied to the swirl chamber and the swivel member moves in the axial direction of the swivel member central axis and contacts the through hole of the swirl chamber,A connecting portion between the small-diameter turning member portion on the one end side protruding from the through hole and the large-diameter turning member portion on the other end side located in the turning chamber penetrates.Since it is in an unstable state in which point contact is made around the through-hole, it receives a force directly received from the kinetic energy of the washing water and a lift and centrifugal force generated by the kinetic energy, thereby starting the swinging of the swivel member more reliably. It becomes possible.
[0009]
  The above-described present invention can take the following aspects. That is, the swirl chamber is provided with a maximum angle restriction guide portion for restricting the maximum inclination angle of the swirl member in which the swirl chamber member central axis is inclined with respect to the swirl chamber central axis. Even in contact with the maximum angle regulation guide until the maximum inclination angle is reached.The connecting portion between the swivel member part on the one end side and the swivel member part on the other end sideAround the through holeTouchCan be.
  With this configuration, when the swivel member is tilted so that the swivel member central axis is tilted with respect to the swirl chamber central axis, the swivel member slides during point contact while reaching the maximum tilt angle. Because of the contact area, rotation is performed smoothly, sliding resistance is reduced, and wear is reduced.
[0010]
  In this way, the swiveling member makes point contact with the periphery of the through hole.The connecting portion that makes point contact with the enclosure has an inclined surface shape.can do. This way, Inclined surface shape andWith this very simple structure, the contact with the periphery of the through hole of the swirl chamber can be reliably made point contact.
[0011]
  In this case, the swivel partThe inclination of the connecting part of the material with respect to the central axis of the swirl chamber memberThe swivel member can be made larger than the maximum tilt angle at which the swirl member tilts in the swirl chamber. In this way, the swivel member receives the force of the washing water, and the swivel member central axis is tilted with respect to the swirl chamber central axis and the swivel member reaches the maximum inclination angle.The connecting part of the materialAlthough sliding while contacting the periphery of the through hole of the swirl chamber, this sliding can be caused in a point contact state.
[0012]
Moreover, it can also be made to have the protrusion surrounding a through-hole around the through-hole of a turning chamber. This is preferable because the contact between the swivel member and the periphery of the through hole can be more reliably brought into a point contact state.
[0013]
Such protrusions can be formed over a partial range around the through hole. In this way, when cleaning water is supplied to the swirl chamber and the swivel member moves in the direction of the through hole and contacts the periphery of the through hole of the swirl chamber, one side of the swirl member comes into contact with the protrusion, and the other has no protrusion. It will come into contact with the periphery of the hole. Therefore, the swiveling member swings so that its central axis is tilted from the central axis of the swirling chamber. Compared to the case where there is no such tilt, the swirling member has a force directly received from the kinetic energy of washing water and the kinetic energy. Largely receives the lift and centrifugal force generated. For this reason, it becomes possible to start rocking | fluctuation in a turning member more reliably.
[0014]
In this case, this protrusion in a partial range around the through hole can have an inclined structure that is smoothly inclined along the circumferential direction of the through hole. In this way, it becomes possible to ensure that the swivel member central axis is inclined with respect to the central axis of the swirl chamber, and that the swivel member is smoothly rotated.
[0015]
Thus, when the swivel member is tilted by the protrusions around the through hole, the swivel member comes into contact with the protrusion, and the swivel member central axis is inclined with respect to the swirl chamber central axis so that the swivel member abuts the swirl chamber and tilts. It can be made smaller than the maximum inclination angle obtained. In this way, the swivel member tilted in contact with the protrusion can be further tilted to the maximum tilt angle. In other words, the protrusions do not regulate the maximum tilt angle of the swivel member, and therefore, the projections regulate the motion of the swivel member until the initial tilt angle and the maximum tilt angle after swinging are reached. Therefore, the swinging can be performed smoothly, the sliding resistance is reduced, and the swinging can be performed efficiently.
[0016]
In addition, a protrusion that interferes with the swivel member in the swirl chamber central axis may be provided on the swirl chamber bottom surface facing the through hole. In this way, when the swivel member swings so that the swivel member central axis is tilted from the swirl chamber central axis, the swivel member central axis is already tilted from the swirl chamber central axis in the initial swing state. Therefore, compared to the case where the central axis of the swivel member is not tilted in this way, the swivel member receives the force directly received from the kinetic energy of the washing water and the lift and centrifugal force generated by the kinetic energy. Thus, it becomes possible to start swinging of the turning member.
[0017]
In this case, the angle at which the swivel member interferes with the protrusion and the swivel member central axis tilts with respect to the swirl chamber central axis can be made smaller than the maximum inclination angle at which the swivel member can incline with the swirl chamber. If it carries out like this, the turning member leaning by contact | abutting with the processus | protrusion of the turning chamber bottom face can further incline to the maximum inclination angle. In other words, since the protrusion on the bottom surface of the swirl chamber does not regulate the maximum tilt angle of the swivel member, the movement of the swivel member is not reached until the initial tilt angle and the maximum tilt angle after the swing are reached. There is no restriction, and it is possible to swing smoothly, reducing sliding resistance, and efficiently swinging.
[0018]
In addition, the swiveling member can be formed so that the center of gravity of the swirling member comes to a position eccentric from the central axis in the one end side portion protruding from the through hole to the outside of the swirling chamber. If it carries out like this, the load distribution in the sliding part used as the part which a turning member contacts the circumference | surroundings of the through-hole of a turning chamber will become non-uniform, and a turning member will incline beforehand. Therefore, compared with the case where such inclination does not occur, the swivel member receives a large amount of force directly received from the kinetic energy of washing water and lift and centrifugal force generated by the kinetic energy, and starts swinging in the swivel member. Becomes easy.
[0019]
In this case, the pressure receiving portion of the swirl member receives the force of the washing water flowing into the swirl chamber, the center of gravity is decentered from the central axis by the pressure receiving portion, and the shape of the pressure receiving portion is centered. It can be non-uniform around the axis. If it carries out like this, it will become possible to receive the force of washing water largely in this pressure receiving part, and it will become possible to start swinging in a turning member more certainly.
[0020]
Another cleaning nozzle of the present invention made to achieve the above object is as follows:
A swirl chamber in which cleaning water is supplied along the circumferential surface of the cylindrically formed room;
One end of the swirl chamber is provided in the swirl chamber so that one end protrudes outside the swirl chamber and the other end is positioned in the swirl chamber. A swivel member for discharging wash water from the water flow path,
In the washing nozzle that swirls the swivel member by the force directly received from the kinetic energy of the washing water supplied to the swirl chamber and the lift and centrifugal force generated by the kinetic energy,
The swirl chamber bottom surface facing the through hole has a protrusion that interferes with the swirl member in the swirl chamber center axis.
Even in this case, the swing of the swivel member can be started by the inclination of the central axis of the swivel member in the initial swing state of the swivel member due to the protrusion on the bottom surface of the swirl chamber.
Even in this case, the angle at which the swivel member interferes with the protrusion on the bottom surface of the swirl chamber and the swivel member central axis tilts with respect to the swirl chamber central axis is the maximum at which the swivel member can tilt by contacting the swirl chamber. It can be made smaller than the inclination angle.
[0021]
Another cleaning nozzle of the present invention made to achieve the above object is as follows:
A swirl chamber in which cleaning water is supplied along the circumferential surface of the cylindrically formed room;
One end of the swirl chamber is provided in the swirl chamber so that one end protrudes outside the swirl chamber and the other end is positioned in the swirl chamber. A swivel member for discharging wash water from the water flow path,
In the washing nozzle that swirls the swivel member by the force directly received from the kinetic energy of the washing water supplied to the swirl chamber and the lift and centrifugal force generated by the kinetic energy,
The swivel member is characterized in that the center of gravity is formed at a position deviated from a central axis in a portion of the one end side projecting from the through hole to the outside of the swirl chamber.
Even in this case, it becomes easy to start swinging of the turning member due to non-uniform load distribution due to eccentricity of the center of gravity.
Even in this case, the pressure receiving portion of the swirling member receives the force of the cleaning water flowing into the swirl chamber, and the pressure receiving portion causes the center of gravity to be decentered from the central axis. Can have a non-uniform shape around the central axis.
[0022]
Moreover, in these washing nozzles, the swirl chamber may have a water leakage portion that causes water leakage from around the through hole. In this way, it becomes possible to reduce the pressure in the swirl chamber as compared with the case where water is not leaked, and the frictional resistance of the sliding portion that is a contact portion between the swirl member and the periphery of the through hole of the swirl chamber is reduced. The swinging member can be started more reliably.
Moreover, this water leak part can have a water leak port formed in a part around the through hole of the swirl chamber. If it carries out like this, it will become possible to let water leak from the sliding part which is a contact part of the turning member and the circumference | surroundings of the through-hole of a turning chamber by simple structure, and not only can reduce frictional resistance, but also a water leakage part The swivel member can be tilted by the force in the leakage of water.
Further, in the water leakage portion, at least one of the through hole of the swirl chamber and the swirl member located in the through hole can have a substantially elliptical or oval structure. In this way, with a simple configuration, it is possible to cause water leakage from the sliding portion that is the contact portion between the swirling member and the periphery of the through hole of the swirling chamber, and the central axis of the swirling member becomes the central axis of the swirling chamber. Even if it is inclined, it can be rotated smoothly.
[0023]

  The present inventionShower equipmentIn the cleaning nozzle that swings the swivel member, the cleaning nozzle and a part of the swivel member are slid in direct contact with each other, and since there is no seal portion, a slight water leak occurs from the sliding portion. Therefore, when the cleaning nozzle of the present invention is used in a shower device used in a bathroom or the like, the water cleaning nozzle of the present invention is particularly suitable because a slight water leak at the sliding portion is not a concern. Further, when the sliding portion is slightly leaked, a lubricating action of the sliding portion by the cleaning water is expected, the sliding resistance is lowered, and the wear is reduced.
  Further, by causing the washing water to oscillate and discharge, a wide range of washing can be performed with a low flow of washing water, and a comfortable stimulation can be obtained by oscillating and discharging the washing water.
  Moreover, when the shower apparatus of this invention is used as a scalp washing | cleaning apparatus, since the washing water rocks and discharges, it becomes possible to remove efficiently the sebum with which the pores were clogged.
  In addition, the apparatus can be simplified by being able to be used with direct water pressure.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are configuration diagrams of a cleaning nozzle used in the first embodiment of the present invention, FIG. 1 is a perspective view from above of the cleaning nozzle, and FIG. 2 is a transparent sectional view from the side of the cleaning nozzle. . When the cleaning water supplied from a water supply source (not shown) is supplied to the cleaning nozzle 1, it is supplied in the order of the water flow path 3, the swirl chamber inflow path 4, and the swirl chamber 5 provided in the cleaning nozzle 1. The swirl chamber inflow channel 4 is configured to have a smaller water flow cross-sectional area than the water flow channel 3, and is configured to be supplied with cleaning water from a tangential direction with respect to the center of the swirl chamber 5.
[0026]
In the swirl chamber 5, a projection 9, a through hole 8 and a maximum angle restriction guide 12 are provided on the central axis 14 of the swirl chamber.
[0027]
A swirl member 2 is provided inside the swirl chamber 5 with one end protruding into the through hole 8, and the swivel member 2 interferes with the protrusion 9 at the interference portion 10.
With the above configuration, the central axis 13 of the portion protruding into the through hole 8 of the swivel member 2 is inclined with respect to the central axis 14 of the swirl chamber.
[0028]
Further, the swivel member 2 is provided with a water supply port 6 through which the cleaning water is supplied and a water discharge port 7 through which the cleaning water is finally discharged through the water supply port 6. Since the contact portion 11 with the periphery of the through hole 8 has a tapered structure, the periphery of the through hole 8 of the swirl chamber 5 and the swivel member 2 are configured to be in point contact.
[0029]
  The case where the cleaning water is discharged in the configuration of FIG. 1 will be described with reference to FIG. 3. The cleaning water supplied to the cleaning nozzle 1 has a flow velocity due to the swirl chamber inflow passage 4 having a smaller water passage area than the water passage 3. It flows into the swirl chamber 5 in a state where the kinetic energy is increased by being accelerated. Further, since the swirl chamber inflow passage 4 is configured to flow wash water from the tangential direction to the swirl chamber 5, the wash water flowing into the swirl chamber 5 swirls inside the swirl chamber 5.
  At this time, the swirling member 2 receives a force in the water discharge direction of the washing water along the central axis of the swirling chamber due to the pressure in the swirling chamber 5, and the central axis 13 of the portion protruding from the through hole of the swirling member is: Protrusion 9 and interference portion trying to be parallel to center axis 14 of swirl chamberTo 10Lean more.
  The tilted swivel member 2 receives a force directly received from the washing water and a lift and centrifugal force generated by the kinetic energy, as compared with a case where the tilted swivel member 2 is not tilted. Oscillation is caused by further tilting with respect to the central axis 14 of the swirl chamber.
  Further, the contact portion 11 of the swirl member 2 with the periphery of the through hole 8 of the swirl chamber 5 has a taper structure, and the periphery of the through hole 8 of the swirl chamber 5 and the swirl member 2 are in point contact with each other. The swivel member 2 is easily inclined with respect to the central axis of the swirl chamber 5 by the force directly received from the shaft and the lift and centrifugal force generated by the kinetic energy.
  Further, the swivel member 2 is configured such that the maximum inclination angle is restricted by a maximum angle restriction guide 12 provided at the upper part of the swirl chamber 5. Since the inclination angle is larger than the inclination angle due to the movement, the turning member 2 is in point contact until reaching the maximum inclination angle due to the oscillation.
  Therefore, there is nothing that regulates the movement of the swivel member 2 from the initial inclination to the maximum inclination angle, and it is possible to perform the swinging smoothly, and the swinging is performed efficiently with little sliding resistance.
[0030]
The trajectory of the cleaning water discharged in the above configuration will be described. The cleaning water swirls in the swirl chamber 5 and swings the swivel member 2, so that the spout 7 provided on the swivel member 2 The water to be sprayed and spouted is spouted while drawing a trajectory that expands spirally, as the spout 7 swings while changing the water discharge direction as the swivel member 2 swings. Accordingly, the water discharge can be swung along a trajectory much larger than the trajectory of the water discharge port 7 provided in the swivel member 2.
[0031]
A second embodiment will be described with reference to the drawings. 4 to 10 are configuration diagrams of the cleaning nozzle used in the second embodiment of the present invention, FIG. 4 is a perspective view from above of the cleaning nozzle, and FIG. 5 is a perspective sectional view from the side of the cleaning nozzle. .
When the cleaning water supplied from a water supply source (not shown) is supplied to the cleaning nozzle 21, it is supplied in the order of a water passage 23, a swirl chamber inflow passage 24, and a swirl chamber 25 provided in the cleaning nozzle 21.
The swirl chamber inflow passage 24 is configured to have a smaller water flow cross-sectional area than the water flow passage 23, and is configured to be supplied with wash water from a tangential direction with respect to the center of the swirl chamber 25.
[0032]
Inside the swirl chamber 25, a swirl member 22 is provided in a state of projecting into a through hole 33 provided in the swirl chamber, and is configured to be movable in the axial direction of the central axis 31 of the swirl chamber. .
[0033]
Further, the swivel member 22 is provided with a water supply port 26 to which cleaning water is supplied and a water discharge port 27 through which the cleaning water is finally discharged in communication with the water supply port 26.
[0034]
The swirl chamber 25 is provided with a guide 29 that regulates the movement of the swivel member 22. The guide 29 will be described in detail with reference to the drawings. 7 is a perspective view of the guide 29 from below, FIG. 6 is a cross-sectional view taken along line AA in FIG. 7, and FIG. 6 is seen from the same direction as the cross-sectional view from the side of the cleaning nozzle 21 in FIG.
The guide 29 has a maximum angle regulation guide portion 30 that regulates the swing angle of the through hole 33 and the turning member 22, and a contact portion between the turning member 22 and the through hole 33 around the through hole of the turning member 22. A protrusion 28 is provided to incline the central axis 32 of the portion protruding to 33 with respect to the central axis of the swirl chamber 25. The protrusion 28 has a smooth inclined structure. The inclined structure will be described in detail. The shaded portion in FIG.
As shown in FIG. 7, the distance in the circumferential direction of the protrusion 28 is X, and the upper point of the end of the protrusion is 0 and the lower point is 1. Further, as shown in FIG. 6, when the Y axis is provided in the height direction of the protrusion 28, the lowest point of the protrusion is 0, and the highest point is 1, the relationship between X and Y is as shown in FIG. It is like that. As can be seen from the above, the protrusion 28 has the lowest height when it is X0, and gradually increases in the circumferential direction, increases the height on the axis of the AA section, and gradually increases the height. It is the lowest point when X1 is lowered. That is, the protrusion 28 has a smooth inclined structure in the circumferential direction of rotation.
The protrusion 28 is provided only in one place in the circumferential direction of the rotational movement of the turning member 22 and is provided unevenly in the circumferential direction of the rotational movement.
[0035]
  The case where the cleaning water is discharged in the configuration of FIG. 4 will be described with reference to FIGS. 9 and 10. The swirl chamber inflow passage in which the cleaning water supplied to the cleaning nozzle 21 has a smaller water passage area than the water passage 23. The flow velocity is increased by 24 and flows into the swirl chamber 25 with the kinetic energy increased. Since the swirl chamber inflow passage 24 is configured to flow cleaning water into the swirl chamber 25 from a tangential direction, the wash water flowing into the swirl chamber 25 swirls inside the swirl chamber 25. When the swirl chamber 25 is filled with cleaning water and the pressure P in the swirl chamber rises, the swirl member 22 moves in the axial direction of the central axis 31 of the swirl chamber and is pressed against the guide 29 as shown in FIG. The central axis 32 of the portion protruding from the through hole 33 of the revolving member 22 by the portion 28 is in a state having a certain inclination angle from the central axis 31 of the revolving chamber.
  The tilted swivel member 22 receives a large amount of force directly received from the washing water and lift and centrifugal force generated by the kinetic energy as compared with the case where the tilt member 22 is not tilted. Oscillation is caused by further tilting with respect to the central axis 31 of the swirl chamber.
  By the protrusion 28, the angle at which the turning member 22 is inclined is set to be smaller than the maximum inclination angle of the turning member 22 by the maximum angle restriction guide portion 30. Therefore, the swivel member from the initial tilt to the maximum tilt angle22There is nothing that regulates the movement, and it is possible to swing smoothly, and the swinging is performed efficiently with little sliding resistance.
  Further, since the protrusion 28 has a smooth inclined structure, the swinging member 22 is smoothly swung.
[0036]
The trajectory of the cleaning water discharged with the above configuration will be described. As shown in FIG. 10, the cleaning water is provided in the turning member 22 by turning in the turning chamber 25 and swinging the turning member 22. The cleaning water sprayed and discharged from the water discharge port 27 is discharged while drawing the spirally expanded trajectory as the water discharge port 27 swings while changing the water discharge direction as the turning member 22 swings. Therefore, the water discharge can be swung along a trajectory far larger than the trajectory of the water discharge port 27 provided in the turning member 22.

The case where the cleaning water is discharged in the configuration of FIG. 11 will be described with reference to FIG. 17. The cleaning water supplied to the cleaning nozzle 41 is flowed by the swirl chamber inflow passage 44 whose water passage area is narrower than the water passage 43. When the kinetic energy is increased, the kinetic energy flows into the swirl chamber 45. Since the swirl chamber inflow passage 44 is configured to allow the wash water to flow into the swirl chamber 45 from a tangential direction, the wash water flowing into the swirl chamber 45 swirls inside the swirl chamber 45.
When the swirl chamber 45 is filled with wash water and the pressure P in the swirl chamber rises, the swivel member 42 is pressed against the guide 49, but the wash water leaks through the through hole 48, so the pressure in the swirl chamber 45 is not leaked. Lower than when not. Therefore, since the force with which the swiveling member 42 is pressed against the guide 49 is reduced, the center of the portion of the swiveling member 42 that protrudes into the through hole 48 by receiving the force directly received from the washing water and the lift and centrifugal force generated by the kinetic energy. The shaft 53 is easily inclined with respect to the central shaft 51 of the swirl chamber.
Further, since the through hole 48 is elliptical, the swinging motion of the turning member 42 is smoothly performed.
[0043]
Further, since the swivel member 42 and the contact portion around the through hole 48 are in point contact by the protrusion 54, the swivel member 42 receives the force directly received from the purified water and the lift and centrifugal force generated by the kinetic energy. The central axis 53 of the portion protruding into the through hole 48 of the receiving and turning member 42 is easily inclined with respect to the central axis 51 of the turning chamber.
[0044]
Further, since the swivel member 42 has a pressure receiving portion 52 provided with a center of gravity at a position deviated from the central axis 53 of the portion projecting into the through hole 48 of the swivel member 42, the swivel member 42 is disposed in the swirl chamber 45. Since the load distribution at the sliding part, which is the contact part with the periphery of the through hole, becomes uneven and the swivel member 42 is tilted in advance, it swings by receiving the force directly received from the purified water and the lift and centrifugal force generated by the kinetic energy. It becomes easy to start.
[0045]
Since the shape of the pressure receiving part 52 is not uniform in the circumferential direction of the rotation, the force directly received from the purified water and the lift and centrifugal force generated by the kinetic energy are more strongly received, so that the oscillation can be easily started.
[0046]
The trajectory of the cleaning water discharged in the above configuration will be described. As shown in FIG. 17, the cleaning water swirls in the swirl chamber 45 to swing the swivel member 42, thereby providing the swirl member 42. The washing water sprayed and discharged from the water discharge port 47 is discharged while drawing the orbit spirally expanded as the water discharge port 47 swings while changing the water discharge direction as the turning member 42 swings. Accordingly, it is possible to swing the water discharge along a trajectory far larger than the trajectory of the water discharge port 47 provided in the turning member 42.
[0047]
A fourth embodiment will be described with reference to the drawings. 18 to 22 are configuration diagrams of the cleaning nozzle used in the fourth embodiment of the present invention. FIG. 18 is a perspective view from above of the cleaning nozzle, and FIG. 19 is a transparent sectional view from the side of the cleaning nozzle. .
When the cleaning water supplied from a water supply source (not shown) is supplied to the cleaning nozzle 61, the water flow path 63, the swirl chamber inflow path 64, and the swirl chamber 65 provided in the cleaning nozzle 61 are sequentially supplied. The swirl chamber inflow passage 64 is configured to have a smaller water flow cross-sectional area than the water flow passage 63, and is configured to be supplied with cleaning water from a tangential direction with respect to the center of the swirl chamber 65.
[0048]
A swirl member 62 is provided inside the swirl chamber 65 in a state of protruding into a through hole 74 provided in the swirl chamber. The swirl member 62 includes a water supply port 66 to which cleaning water is supplied and the water supply port. A water discharge port 67 through which the cleaning water is finally discharged is provided.
[0049]
  Further, the cleaning nozzle 61 has a guide for restricting the movement of the swivel member 62.69It is provided. The guyDo 69This will be described in detail with reference to the drawings.FIG.Is a guyTo 69FIG. 21 is a cross-sectional view taken along line AA in FIG. 20, and FIG. 21 is seen from the same direction as the cross-sectional view from the side of the cleaning nozzle 61 in FIG.
  GuyTo 69Are provided with a water leakage port 68 at the contact portion around the maximum angle restriction guide part 70 and the through hole 74 for restricting the swing angle of the turning member 62 and the through member 74.
[0050]
  Further, the swivel member 62 is provided with a counterweight 72. The counterweight 72 is provided only at one place on the turning member 62 and is not uniform in the circumferential direction of rotation. Therefore counterwayG 72Thus, the center of gravity of the turning member 62 is arranged at a position eccentric from the central axis 73 of the portion protruding into the through hole 74 of the turning member 62.
[0051]
  The case where the cleaning water is discharged in the configuration of FIG. 18 will be described with reference to FIG. 22. The cleaning water supplied to the cleaning nozzle 61 has a flow velocity by the swirl chamber inflow passage 64 whose water passage area is narrower than the water passage 63. When the kinetic energy is increased, the kinetic energy increases and flows into the swirl chamber 65. Since the swirl chamber inflow path 64 is configured to allow the wash water to flow into the swirl chamber 65 from a tangential direction, the wash water flowing into the swirl chamber 65 swirls inside the swirl chamber 65.
  Further, when the swirl chamber 65 is filled with cleaning water and the pressure P in the swirl chamber rises, the swivel member 62 is pressed against the contact portion around the swivel member 62 and the through-hole 74. Since water leaks, the pressure in the swirl chamber 65 becomes lower than when there is no water leak. Therefore, the turning member 62 and the turning member 62 and the penetrating through74 holesSince the force pressed against the contact portion of the enclosure is reduced, the swiveling member 62 is penetrated by receiving the force directly received from the washing water and the lift and centrifugal force generated by the kinetic energy.In hole 74The central axis 73 of the protruding portion is easily inclined from the central axis 71 of the swirl chamber.
  Further, the swivel member 62 is easily tilted by receiving a force of water leakage from the water leakage port 68.
[0052]
  Further, the pivot member 62 has a center of gravity of the pivot member 62 and a through hole of the pivot member 62.74Since there is a counterweight 72 that is eccentric from the central axis 73 of the protruding portion, the load distribution in the sliding portion that is the contact portion between the swivel member 62 and the periphery of the through hole of the swirl chamber 65 becomes non-uniform, and the swivel member 62 Is inclined in advance, it becomes easy to start swinging by strongly receiving the force directly received from the purified water and the lift and centrifugal force generated by the kinetic energy.
[0053]
Further, since the shape of the swivel member becomes non-uniform in the circumferential direction of the rotation due to the counterweight 72, it is easy to start swinging by receiving more strongly the force directly received from the purified water and the lift and centrifugal force generated by the kinetic energy. Become.
[0054]
The trajectory of the cleaning water discharged in the above configuration will be described. As shown in FIG. 22, the cleaning water is provided in the turning member 62 by turning in the turning chamber 65 and swinging the turning member 62. The washing water sprayed and discharged from the water discharge port 67 is discharged while drawing a spirally expanded trajectory as the water discharge port 67 swings while changing the water discharge direction as the turning member 62 swings. Therefore, the water discharge can be swung along a trajectory far larger than the trajectory of the water discharge port 67 provided in the turning member 62.
[0055]
A fifth embodiment will be described with reference to the drawings. Referring to FIGS. 23 and 24, FIG. 23 is a cross-sectional view from the side of the shower device when the cleaning nozzle shower of the present invention is used as a shower device, and FIG. 24 is a cross-sectional view taken along line AA in FIG. When the cleaning water supplied from a water supply source (not shown) is supplied to the shower device 81, the water passage 82 provided in the shower device 81, the buffer chamber 83 swirl chamber inflow channel 84, and the swirl chamber 85 are sequentially supplied. The
The swirl chamber inflow channel 84 is configured to have a smaller water flow cross-sectional area than the water flow channel 82, and is configured to supply the wash water into the swirl chamber 85 in a state where the kinetic energy of the wash water is increased.
[0056]
A plurality of swirl chamber inflow passages 84, swirl chambers 85, and swirl members 86 are provided inside the buffer chamber 83.
The swirl chamber 85 is provided with a protrusion 90, a through hole 91, and a maximum angle restriction guide 92 on the central axis of the swirl chamber.
[0057]
A swirl member 86 is provided inside the swirl chamber 85 with one end protruding into the through hole 91, and an interference portion 89 of the swirl member 86 interferes with the protrusion 90.
With the above-described configuration, the central axis of the portion protruding into the through hole 91 of the swivel member 86 is configured to be inclined with respect to the central axis of the swirl chamber.
[0058]
  Each swivel member 86 is provided with a water supply port 87 through which cleaning water is supplied and a water discharge port 88 that communicates with the water supply port 87 and jets and discharges the cleaning water.
  FIG. 23 shows a case where cleaning water is discharged in the configuration of FIG.24If it demonstrates based, the wash water supplied to the shower apparatus 81 will be supplied in order of the water flow path 82, the buffer chamber 83 swirl | vortex chamber inflow path 84, and the swirl | vortex chamber 85.
  Further, since the swirl chamber inflow path 84 is configured to allow the wash water to flow into the swirl chamber 85 from the tangential direction, the wash water flowing into the swirl chamber 85 swirls inside the swirl chamber 85.
  At this time, the swivel member 86 receives a force in the direction of water discharge along the central axis of the swirl chamber due to the pressure in the swirl chamber 85, and the central axis of the portion protruding from the through hole of the swirl member is swirled. It tends to be parallel to the central axis of the chamber but is inclined by the protrusion 90 and the interference portion 89.
  The tilted swivel member 86 receives a force directly received from the washing water and a lift and centrifugal force generated by the kinetic energy, compared with a case where the tilted swivel member 86 is not tilted. It swings further with respect to the central axis of the chamber.
[0059]
There is nothing that regulates the movement of the swivel member 86 from the initial inclination to the maximum inclination angle, and it is possible to perform the swinging smoothly, and the swinging is performed efficiently with little sliding resistance.
[0060]
The case where the cleaning water is discharged with the above configuration will be described with reference to FIG. 25. The cleaning water supplied to the shower device 81 is discharged while being swung by a plurality of swiveling members 86 provided in the shower device 81. The Therefore, the trajectory of the discharged cleaning water is discharged as a plurality of independent swing trajectories, and the human body is cleaned. Therefore, even if the amount of washing water is reduced, it is possible to perform water discharge with a wide area of stimulation and washing, which is effective in saving water.
[0061]
In addition, it is possible to obtain a pleasant stimulation feeling by swinging water discharge, which is suitable for the massage effect of the human body, particularly the head.
Moreover, when this shower apparatus is used for the head, not only can the blood circulation promotion effect by the massage effect be obtained by the rocking water discharge, but also the sebum clogged in the pores can be efficiently removed. It becomes possible.
[0062]
Further, the water supply source has a sufficient water discharge capability even under direct water pressure, but it goes without saying that it is more effective to use a washing water pumping means by a pump for the purpose of enhancing the massage effect.
[0063]
In addition, since the shower device 81 and the swivel member 86 are directly contacted and slid, the washing water is expected to cause a slight water leak from the contact portion between the shower device 81 and the swivel member 86. There is no problem as a device.
