Description

  The disclosed embodiment relates to a water discharge device.

  2. Description of the Related Art Conventionally, as a water discharge device used in, for example, a kitchen or a washroom, there is one that performs shower water discharge. This type of water discharge device includes a water spray plate in which a plurality of water spray holes are formed at the end of the flow channel, and performs shower water discharge by dispersing water discharged from the flow channel to each water spray hole of the water spray plate.

  In such a water discharge device, for example, when the flow rate is reduced, a shower with insufficient momentum may be generated, or water may be dripped without being dispersed in a shower shape. This is because it becomes difficult to obtain a flow rate necessary for forming the shower because the flow rate decreases.

  In view of this, there is known a water discharger in which a packing that can be brought into contact with and separated from the water spray plate is provided in the flow path (see, for example, Patent Documents 1 and 2). This water discharge device moves the packing in the flow channel toward the water spray plate and closes a part of the water spray holes provided in the water spray plate with the packing, thereby reducing the flow rate of water discharged from the remaining water spray holes. Can be increased. Therefore, even if the flow rate is reduced, it is possible to perform appropriate shower water discharge.

  The water outlet includes a first water outlet provided at the center of the tip of the water outlet, and a plurality of second water outlets provided on the outer peripheral side of the first water outlet. The water spray hole is provided at a position facing the second water outlet, and a straight water discharge opening is provided at a position facing the first water outlet. Thereby, shower water discharge and straight water discharge can be switched and used.

Can be prevented.

  Further, the plurality of water spray holes are provided concentrically with respect to the water spray plate, and the packing is annular. Such a configuration is effective, for example, when an opening for straight water discharge is provided at the center of the watering plate.

  The water sprinkling unit 3 is a cap-like member that is detachably attached to the water discharging unit 120 of the water discharging head 6. The water sprinkling unit 3 disperses raw water (normal temperature water, hot water, hot water mixed water) or purified water discharged from the water discharging unit 120 in a shower shape using a watering plate 210 (see FIG. 2) described later.

<2. Configuration of water discharge head and sprinkler>
Next, the structure of the water discharge head 6 and the water sprinkling part 3 is demonstrated with reference to FIG. FIG. 2 is a cross-sectional view of the water discharge head 6 and the water sprinkling unit 3. In the following, raw water (room temperature water, hot water, hot water mixed water) and purified water are collectively referred to simply as “water”. In addition, the water supply source, the hot water supply source, and the water purifier are collectively referred to simply as “water source”.

<2-1. Water discharge head>
First, the configuration of the water discharge head 6 will be described. As shown in FIG. 2, the water discharge head 6 includes a head main body 110 and a water discharge unit 120.

  The head body 110 has, for example, a cylindrical shape (see FIG. 7) and includes a water passage forming member 111 inside. The water flow path forming member 111 is a member that forms a water flow path that guides water supplied from the base portion 4 through the hose to a first water discharge path 123 or a second water discharge path 124 described later of the water discharge section 120.

  The water discharger 120 is provided so as to protrude in the direction substantially orthogonal to the axial direction of the head body 110 with respect to the outer peripheral part of the head body 110. The water discharger 120 has a cylindrical outer peripheral surface, and includes a first water discharge port 121 and a plurality of second water discharge ports 122 at the tip.

  The first water discharge port 121 is provided at the center of the tip of the water discharge unit 120 and discharges the water that has flowed into the first water discharge path 123 toward a straight water discharge opening 211 described later of the water spray unit 3. Moreover, the 2nd water outlet 122 is arranged in the outer periphery side rather than the 1st water outlet 121 at the outer periphery side, and is provided in the outer periphery side. Discharge toward

  Here, the water discharge part 120 which concerns on 1st Embodiment is comprised by the 1st water discharge member 120_1 provided in the water flow path formation member 111 side, and the 2nd water discharge member 120_2 provided in the water sprinkling part 3 side. The first water discharge member 120_1 and the second water discharge member 120_2 are positioned by protrusions or the like so that the positions do not shift when receiving a force in the rotation direction with the water discharge direction as an axis. Further, the first water discharge member 120_1 and the water flow path forming member 111 are provided with a rotation stop fitting structure so that the water discharge portion 120 does not rotate when receiving a force in the rotation direction about the water discharge direction.

  The positions of the first water discharge member 120_1 and the second water discharge member 120_2 are positioned so that the position of the second water discharge path 124 overlaps, and thereby the water from the first water discharge member 120_1 is retained in the second water discharge member 120_2. It can be passed through without water. By reducing the total area of the holes (channels) of the first water discharging member 120_1, the flow rate of the water passing through the holes (channels) of the first water discharging member 120_1 can be increased, and thus the first water discharging member 120_1. When the water that has passed through enters the second water discharge member 120_2, a negative pressure is generated around the water discharge member 120_2, resulting in a water flow involving air. This mixed flow of air and water is discharged from the second water discharge port 122, stirred before being discharged from the water spray holes 212 and 213, and discharged from the water spray holes 212 and 213 as a shower containing bubbles.

  Note that the air drawn into the second water discharge member 120_2 is sucked from a gap provided in the fitting portion between the first water discharge member 120_1 and the second water discharge member 120_2. By adopting such a configuration, a bubble mixed shower that discharges bubble mixed water in which air and water are mixed is realized without leaking water from the gap between the first water discharge member 120_1 and the second water discharge member 120_2. can do.

  In addition, although the example in case the water discharging part 120 is comprised from a some member is shown here, the water discharging part 120 may be comprised by a single member.

  A switching valve 112 is provided in the water passage formed by the water passage forming member 111. The switching valve 112 is a valve body that switches the outflow destination of the water that has flowed into the water passage to the first water discharge passage 123 or the second water discharge passage 124 of the water discharge unit 120. The switching valve 112 is moved along the axial direction of the water discharge head 6 in accordance with the rotation of the operation unit 113 when the operation unit 113 provided at the tip of the head body 110 is rotated, and the water discharge destination is changed. Switch.

  As described above, the water discharge head 6 draws water supplied from the base portion 4 through the hose from the first water discharge port 121 toward the straight water discharge opening 211 of the sprinkling unit 3 or the second water discharge port 122. To the water spray holes 212 and 213 of the water spray unit 3.

<2-2. Sprinkler>
It continues and the structure of the water sprinkling part 3 is demonstrated. The water sprinkling unit 3 is a member that is detachably attached to the water discharging unit 120, and includes a watering plate 210, an outer tube unit 220, and an inner tube unit 230. The water sprinkling part 3 has a cap shape (see FIG. 1), and the water sprinkling plate 210 corresponds to the ceiling part of the cap, and an outer cylinder part 220 is provided on the outer peripheral part of the watering board 210, and the outer cylinder part 220. Further, the inner cylinder portion 230 is provided on the inner peripheral side. The outer cylinder part 220 and the inner cylinder part 230 are provided integrally with the water spray plate 210.

  The watering plate 210 is disposed to face the first water outlet 121 and the second water outlet 122 of the water discharger 120 with a predetermined interval. The water spray plate 210 has a straight water discharge opening 211 at a position facing the first water discharge port 121, and a plurality of water spray holes 212 and 213 at a position facing the second water discharge port 122. Here, the configuration of the watering plate 210 will be specifically described with reference to FIG. FIG. 3 is a view of the watering plate 210 as viewed from below.

  As shown in FIG. 3, the watering plate 210 has a substantially annular shape, and the central opening is a straight water discharge opening 211. The plurality of water spray holes 212 and 213 are arranged concentrically on the outer peripheral side of the straight water discharge opening 211. Specifically, a plurality of water spray holes 212 are arranged in a circle on the outer peripheral side of the straight water discharge opening 211, and a plurality of water spray holes 213 are arranged in a circle on the outer peripheral side.

  A water discharge cap 214 is attached to the straight water discharge opening 211. In addition, a knob portion 215 operated by the user is provided on the outer peripheral portion of the watering plate 210.

  Returning to FIG. 2, the outer cylinder part 220 will be described. The outer cylinder part 220 is integrally provided on the outer peripheral part of the watering plate 210. The outer cylinder portion 220 has a substantially cylindrical shape that protrudes from the outer peripheral portion of the water spray plate 210 toward the water discharge portion 120, and is fitted coaxially to the second water discharge member 120 </ b> _ <b> 2 of the water discharge portion 120. Is done. A seal member 300 is provided between the outer tube portion 220 and the water discharge portion 120, and the water tightness between the outer tube portion 220 and the water discharge portion 120 is ensured by the seal member 300. Further, for example, a metal cover body 240 is attached to the outer peripheral portion of the outer cylindrical portion 220.

  The inner cylinder portion 230 is integrally provided on the inner peripheral portion of the water spray plate 210, specifically, on the opening edge portion of the straight water discharge opening 211. The inner cylinder part 230 has a cylindrical shape that protrudes toward the water discharge part 120, and passes through the flow path from the water discharge part 120 to the water spray plate 210 to the straight water discharge opening 211. The flow path is divided into a flow path from the second water outlet 122 to the water spray holes 212 and 213.

  The water discharged from the first water discharge port 121 of the water discharge unit 120 reaches the straight water discharge opening 211 through the flow path on the inner side of the inner cylinder 230, and is discharged straight from the straight water discharge opening 211. . Further, the water discharged from the second water discharge port 122 of the water discharge unit 120 reaches the plurality of water spray holes 212 and 213 through the flow path outside the inner cylinder part 230, and is formed by the plurality of water spray holes 212 and 213. It is dispersed and shower water is discharged.

<3 types of shower water discharge>
The water discharge device 1 according to the first embodiment can switch between shower water discharge and straight water discharge as described above, and further, “normal shower water discharge” and “high-speed shower water discharge having a higher flow rate than normal shower water discharge”. 2 types of shower water discharge. Below, the structure for implement | achieving these two types of shower water discharge forms is demonstrated.

  As shown in FIG. 2, the water discharge device 1 includes a packing 400 between the water discharge unit 120 and the water spray plate 210. The packing 400 is fixed to the tip of a fixing member 410 attached to the water discharger 120. Further, as shown in FIG. 3, the packing 400 has an annular shape, and is disposed so as to face the watering holes 212 arranged on the inner peripheral side among the plurality of watering holes 212 and 213.

  The water spouting device 1 moves the water sprinkling unit 3 using a displacement mechanism, which will be described later, and causes the water sprinkling plate 210 provided in the water sprinkling unit 3 to abut against or separate from the packing 400, thereby “normal shower water spout”. Switch to "High-speed shower water discharge". This operation will be described with reference to FIGS. FIG. 4 is a diagram illustrating the flow of water during normal shower water discharge. Moreover, FIG. 5 is a figure which shows the flow of the water at the time of high-speed shower water discharge.

  4 and 5 show cross-sectional views when the water discharger 120 and the water sprayer 3 are viewed from a direction different from that in FIG. Specifically, FIGS. 4 and 5 are cross-sectional views cut so that a side cross-section of the regulating member 500 shown in FIG. 2 can be seen.

  As shown in FIG. 4, the water spray plate 210 is separated from the packing 400 during normal shower water discharge. For this reason, the water discharged from the second water discharge port 122 through the second water discharge path 124 is dispersed and discharged into all of the plurality of water spray holes 212 and 213.

  On the other hand, by moving the sprinkling unit 3 using a displacement mechanism described later and displacing the sprinkling plate 210 to the abutting position where it abuts against the packing 400, the shower water discharge mode is switched from the normal shower water discharge mode to the high-speed shower water discharge mode.

  As shown in FIG. 5, the water spray plate 210 is in contact with the packing 400 during high-speed shower water discharge. As described above, the packing 400 is disposed so as to face the water spray hole 212 on the inner peripheral side among the water spray holes 212 and 213 (see FIG. 3). For this reason, when the water spray plate 210 abuts on the packing 400, the water spray hole 212 on the inner peripheral side of the plurality of water spray holes 212 and 213 is closed with the packing 400. As a result, the water discharged from the second water discharge port 122 through the second water discharge passage 124 is dispersed only in the outer peripheral water spray holes 213 and discharged in the shower.

  Thus, the water spray holes 212 and 213 are partially blocked by the packing 400, so that the number of the water spray holes 212 and 213 through which water can flow is reduced, that is, the total value of the channel cross-sectional areas is reduced. The flow rate of water discharged from each of the water spray holes 212 and 213 increases as the total value of the channel cross-sectional areas decreases. Therefore, the shower water discharged from the outer side sprinkling holes 213 that are not blocked by the packing 400 is high-speed shower water discharged at a higher flow rate than that during normal shower water discharge.

  As described above, the water discharge device 1 according to the first embodiment can switch between normal shower water discharge and high-speed shower water discharge. For this reason, the user can continue shower water discharge by switching from normal shower water discharge to high-speed shower water discharge even when the flow rate drops during normal shower water discharge and the shower water discharge cannot be performed properly. it can.

  Here, an example in which the inner peripheral watering hole 212 is closed with the packing 400 is shown, but the outer peripheral watering hole 213 may be closed with the packing 400. In this case, the packing 400 should just be arrange | positioned in the position facing the water spray hole 213 of an outer peripheral side.

  Moreover, as a cause of the flow rate decreasing, for example, a decrease in the original pressure when water is discharged at a plurality of locations at the same time can be mentioned. As another cause, a pressure loss due to the water purifier is also conceivable. That is, when the raw water / purified water switching lever 8 (see FIG. 1) is operated to switch from the raw water to the purified water, the flow rate decreases due to the pressure loss caused by the water purifier, and the shower water discharge can be appropriately performed. It may not be possible. Even in such a case, the user can perform shower water discharge with purified water at a sufficient flow rate by switching from normal shower water discharge to high-speed shower water discharge.

<4. Displacement mechanism>
As described above, switching between “normal shower water discharge” and “high-speed shower water discharge” is performed by bringing the water spray plate 210 into contact with and separating from the packing 400. The water discharge device 1 includes a displacement mechanism that displaces the water spray plate 210 between a “separation position” separated from the packing 400 and a “contact position” that contacts the packing 400.

  An example of the configuration of the displacement mechanism will be described with reference to FIG. 6 is a schematic enlarged view of a portion H shown in FIG.

  As shown in FIG. 6, the external thread part 120a is formed in the outer peripheral surface of the 1st water discharging member 120_1 with which the water discharging part 120 is provided. Specifically, the external thread part 120a is formed in the outer peripheral surface of the cylinder part which forms the 1st water discharge port 121 among the 1st water discharge members 120_1. Moreover, the internal thread part 230a screwed together with the said external thread part 120a is formed in the internal peripheral surface of the inner cylinder part 230 with which the water sprinkling part 3 is provided. By screwing the female screw portion 230a of the inner cylinder portion 230 into the male screw portion 120a of the first water discharge member 120_1, the inner cylinder portion 230 is screwed into the first water discharge member 120_1, and the water spray portion 3 is attached to the water discharge portion 120. It will be attached.

  Thus, the water discharging apparatus 1 which concerns on 1st Embodiment is provided with the external thread part 120a and the internal thread part 230a as a displacement mechanism, and rotates the water sprinkling part 3 to the rotation direction centering on a water discharge direction. As a result, the sprinkler 3 rotates and moves spirally. Thereby, the water spray plate 210 can be displaced between a “separation position” separated from the packing 400 and a “contact position” contacting the packing 400.

  For example, in the state where the watering plate 210 is in the “separated position”, that is, in the “normal shower water discharge” state, when the user rotates the watering part 3 clockwise, the watering part 3 rises while spirally rotating. Then, the water spray plate 210 is displaced to the “contact position”. That is, switching to “high-speed shower water discharge”. In addition, in the state where the watering plate 210 is in the “contact position”, that is, in the “high-speed shower water discharge” state, when the user rotates the watering unit 3 counterclockwise, the watering unit 3 rotates in a spiral shape. Then, the water spray plate 210 is moved downward to the “separated position”. That is, it switches to “normal shower water discharge”.

  As described above, the water discharge device 1 according to the first embodiment displaces the water spray plate 210 provided outside the water discharge device 1 to switch between “normal shower water discharge” and “high-speed shower water discharge”. For this reason, complication of an internal structure can be suppressed compared with the structure which displaces the packing provided in the inside of a water discharging apparatus like the conventional water discharging apparatus. Therefore, according to the water discharging apparatus 1 which concerns on 1st Embodiment, the flow rate of shower water discharge can be switched, suppressing complication of an internal structure. Moreover, the structure (the 1st water discharge port 121, the 1st water discharge path 123, the opening part 211 for straight water discharge, etc.) for performing with straight water discharge is arrange | positioned freely with respect to the water discharge apparatus 1 by suppressing complication of an internal structure. can do.

  Moreover, the water discharging apparatus 1 which concerns on 1st Embodiment decided to provide the external thread part 120a and the internal thread part 230a as a displacement mechanism. Therefore, according to the water discharging apparatus 1 which concerns on 1st Embodiment, the watering board 210 can be displaced with a simple structure. In addition, when the user wants to switch the form of shower water discharge, the user only needs to grasp and rotate the water spray unit 3 and can operate with one hand, so the switching operation is easy. It is also possible to perform switching with a small operation amount. For example, in the water discharging apparatus 1, the watering part 210 can be displaced about 1.5 mm by rotating the watering part 3 by 30 degrees.

  Moreover, in the water discharging apparatus 1 which concerns on 1st Embodiment, it is set as the structure which makes the outer cylinder part 220 of the water sprinkling part 3 fit in the 2nd water discharging member 120_2 of the water discharging part 120. FIG. Thereby, since it becomes difficult to produce inclination etc. in the watering board 210, it is easy to ensure the sealing performance between the watering board 210 and the packing 400. FIG.

  In addition, knob parts 215 and 222 are provided on the outer peripheral parts of the watering plate 210 and the outer cylinder part 220 (see FIG. 7). Providing such knobs 215 and 222 makes it easier for the user to apply force to the sprinkler 3, so switching between “normal shower water discharge” and “high-speed shower water discharge” is performed with a smaller force. Can do.

  Here, an example in which the male screw portion 120a is formed on the outer peripheral surface of the first water discharge member 120_1 and the female screw portion 230a is formed on the inner peripheral surface of the inner cylinder portion 230 is shown. The place where the female screw portion 230a is formed is not limited to the above example. For example, the male screw portion 120a may be formed on the outer peripheral surface of the second water discharge member 120_2 provided in the water discharge portion 120, and the female screw portion 230a may be formed on the inner peripheral surface of the outer cylinder portion 220 provided in the water sprinkling portion 3.

  Moreover, although the example in which the external thread part 120a is formed in the water discharge part 120 and the internal thread part 230a is formed in the water spray part 3 was shown here, conversely, the internal thread part is formed in the water discharge part 120. 230a may be formed and the male screw part 120a may be formed in the water sprinkling part 3. For example, the female screw portion 230a may be formed on the inner peripheral surface of the second water discharge member 120_2 included in the water discharge portion 120, and the male screw portion 120a may be formed on the outer peripheral surface of the inner cylinder portion 230 included in the water sprinkling portion 3.

  In addition, the outer cylinder part 220 and the inner cylinder part 230 with which the water sprinkling part 3 is provided correspond to an example of a “cylindrical part” that is screwed into the water discharge part 120.

<5. Regulatory member that regulates the displacement of the watering plate>
In the water discharging apparatus 1 according to the first embodiment, for example, when the water spraying unit 3 is rotated in a direction in which the water spraying plate 210 is further separated from the packing 400 than the “separation position” due to an erroneous operation of the user, for example, On the other hand, there is a possibility that the water sprinkling part 3 may come off from the water discharge part 120.

  For this reason, the water discharging apparatus 1 according to the first embodiment includes the regulating member 500 that regulates the displacement of the water spray plate 210 when the water spray plate 210 is further separated from the packing 400 than the “separation position” described above. Provide (see FIG. 2).

  Specifically, as shown in FIG. 2, the inner peripheral surface of the inner cylinder part 230 provided in the water spray part 3 is a large diameter part provided on the water spray plate 210 side, and on the water discharge part 120 side from this large diameter part. The provided small diameter portion has a shape that continues through the step surface 231.

  The regulating member 500 is a thin plate-like member (see FIG. 4), and is fixed to the water discharger 120 by inserting the tip 510 into the first water discharger 121. A locking portion 520 that is wider than the distal end portion 510 is provided at the proximal end portion of the regulating member 500.

  The locking portion 520 is disposed to face the step surface 231 of the inner cylinder portion 230 in a state where the distal end portion 510 is inserted into the first water discharge passage 123. Specifically, when the water spray plate 210 is in the “separated position”, the locking portion 520 is disposed at a position where it comes into contact with the stepped surface 231 of the inner cylinder portion 230 or at a position farther from the packing 400 than this position. The Rukoto. Accordingly, when the water spray plate 210 is further separated from the packing 400 than the “separation position”, the step surface 231 of the inner cylindrical portion 230 abuts on the locking portion 520 and the displacement of the water spray plate 210 is restricted.

  Thus, in the water discharging apparatus 1 which concerns on 1st Embodiment, when the water spray plate 210 tends to separate from the packing 400 rather than "separation position", the displacement of the water spray plate 210 is controlled by the control member 500. . For this reason, it can prevent that the water sprinkling part 3 remove | deviates from the water discharging part 120 by a user's misoperation etc.

  As described above, the water discharging device 1 according to the first embodiment includes the water discharging device main body 2, the water spray plate 210, the packing 400, the male screw portion 120a and the female screw portion 230a as a displacement mechanism. The water discharge device main body 2 has a water discharge portion 120 provided with a first water discharge port 121 and a second water discharge port 122 at a distal end portion, and distributes water supplied from a water source to the first water discharge port 121 or the second water discharge port. It discharges from the spout 122. The water spray plate 210 has a plurality of water spray holes 212 and 213 and is disposed to face the first water outlet 121 and the second water outlet 122 with a predetermined interval. The packing 400 is disposed between the water spray plate 210 and the first water outlet 121 and the second water outlet 122, and faces a part of the water holes 212 among the plurality of water holes 212 and 213. The displacement mechanism displaces the water spray plate 210 between a separation position separated from the packing 400 and a contact position that contacts the packing 400.

  Therefore, according to the water discharging apparatus 1 which concerns on 1st Embodiment, the flow rate of shower water discharge can be switched, suppressing complication of an internal structure.

(Second Embodiment)
Next, a second embodiment will be described. In the second embodiment, a modified example of the displacement mechanism will be described with reference to FIGS. 7-9 is a figure which shows the 1st modification-3rd modification of a displacement mechanism. 7 to 9, the cover body 240 is omitted. Moreover, in the following description, about the part similar to the already demonstrated part, the code | symbol same as the already demonstrated part is attached | subjected, and the overlapping description is abbreviate | omitted.

  First, a first modification will be described with reference to FIG. As shown in FIG. 7, the outer cylinder part 220A provided in the water sprinkling part 3A is provided with an inclined groove 221 that is inclined at a predetermined angle with respect to the axial direction of the outer cylinder part 220A. The inclined groove 221 extends to the upper end edge of the outer cylindrical portion 220A. A plurality of the inclined grooves 221 are provided at predetermined intervals along the circumferential direction of the outer cylindrical portion 220A. Here, the inclined groove 221 has a shape penetrating the outer peripheral surface and the inner peripheral surface of the outer cylindrical portion 220A, but the inclined groove 221 is provided at least on the inner peripheral surface side of the outer cylindrical portion 220A. That's fine.

  A protrusion 125 that is locked to the inclined groove 221 is provided on the outer peripheral surface of the water discharger 120A. A plurality of protrusions 125 are provided along the circumferential direction of the water discharger 120 </ b> A at the same interval as the inclined grooves 221.

  As described above, the water discharge device 1 may include the inclined groove 221 and the protrusion 125 instead of the male screw portion 120a and the female screw portion 230a described above as a displacement mechanism. In such a case, the water discharge device 1 can bring the water spray plate 210 into contact with and away from the packing 400 by using this displacement mechanism and converting the rotational force applied to the outer cylindrical portion 220 </ b> A into a helical rotation.

  Specifically, when the user rotates the water sprinkling part 3A, a rotational force along the circumferential direction is applied to the outer cylindrical part 220A of the water sprinkling part 3A. The displacement mechanism converts the direction of this force into the inclination direction of the inclined groove 221 to spirally rotate the outer cylindrical portion 220 </ b> A along the inclined groove 221. Thus, the water spray plate 210 is displaced to the “contact position” or “separation position” by moving along the axial direction of the outer cylinder part 220A together with the outer cylinder part 220A.

  For example, FIG. 7 shows a state where the watering plate 210 is in the “contact position”, that is, a “high-speed shower water discharge” state. In this state, when the user rotates the sprinkling part 3A counterclockwise, the sprinkling part 3A descends while rotating spirally, and the sprinkling plate 210 is displaced to the “separation position”. That is, it switches to “normal shower water discharge”. Further, when the water sprinkling plate 210 is in the “separated position”, that is, in the “normal shower water discharge” state, when the user rotates the water sprinkling part 3A clockwise, the water sprinkling part 3A rotates while spirally rising. Then, the water spray plate 210 is displaced to the “contact position”. That is, switching to “high-speed shower water discharge”.

  Thus, according to the displacement mechanism which concerns on a 1st modification, the water spray board 210 is displaced by simple structure similarly to the displacement mechanism (male screw part 120a and female screw part 230a) which concerns on 1st Embodiment. Can do. In addition, the shower water discharge mode can be easily switched.

  In addition, the water discharging apparatus 1 is provided with the control member 500 (refer FIG. 2). Therefore, when the sprinkler plate 210 is further separated from the packing 400 than the “separation position”, the displacement of the sprinkler plate 210 is restricted by the restricting member 500. It can prevent coming off from 120A.

  The inclined groove 221 and the protrusion 125 as a displacement mechanism are provided above (on the head body 110 side) above the seal member 300 (see FIG. 2). That is, the inclined groove 221 and the protrusion 125 are provided on the outer space side of the inner space and the outer space that are separated by the seal member 300. For this reason, this displacement mechanism is unlikely to affect the water tightness between the outer tube portion 220A and the water discharge portion 120A. Here, an example in which the inclined groove 221 is provided in the outer cylindrical portion 220A and the protrusion 125 is provided in the water discharging portion 120A is shown, but the present invention is not limited thereto, and the inclined groove 221 is provided in the water discharging portion 120A. The protruding portion 125 may be provided on the cylindrical portion 220A.

  In the first modification, a displacement mechanism is provided between the water discharger 120A and the outer cylinder 220A. Thus, since the displacement mechanism is provided outside the water discharge device main body 2, the internal structure of the water discharge device main body 2 does not become complicated. Further, by providing a displacement mechanism between the water discharger 120A and the outer cylinder part 220A so that the displacement mechanism is not exposed to the outside, it is possible to obtain a high design appearance.

  Next, a displacement mechanism according to a second modification will be described with reference to FIG. As shown in FIG. 8, the outer cylinder part 220B with which the water sprinkling part 3B is provided is provided with the inclination groove | channel 223 instead of the inclination groove | channel 221 shown in FIG. Other configurations are the same as those shown in FIG.

  Unlike the above-described inclined groove 221, the inclined groove 223 does not extend to the upper end edge of the outer cylindrical portion 220 </ b> B and has a shape in which both ends are closed. As a result, when the water spray plate 210 is further separated from the packing 400 than the “separation position”, the protrusion 125 abuts against the end of the inclined groove 223, thereby further restricting the displacement of the water spray plate 210. .

  Thus, by making the shape of the inclined groove 223 into a shape in which both ends are closed, it is possible to prevent the water sprinkling part 3B from being detached from the water discharging part 120A. Therefore, when the displacement mechanism (the inclined groove 223 and the protrusion 125) according to the second modification is employed, the regulating member 500 illustrated in FIG. 2 is not necessary.

  Next, a displacement mechanism according to a third modification will be described with reference to FIG. In addition, in FIG. 9, in order to understand easily, the structure of the water discharging part 120C and the water sprinkling part 3C is simplified and shown.

  As shown in FIG. 9, the water discharger 120 </ b> C according to the third modification includes a stepped locking part 150 as a displacement mechanism. The stepped locking portion 150 is provided, for example, inside a groove 160 formed over the entire circumference in the circumferential direction with respect to the outer peripheral surface of the water discharger 120C.

  The stepped locking portion 150 includes a first locking surface 151, a slide surface 152 provided closer to the head main body 110 (see FIG. 2) than the first locking surface 151, and the first locking surface 151. And a second locking surface 153 provided on the water spray plate 210 side. The first locking surface 151, the slide surface 152, and the second locking surface 153 are repeatedly arranged in this order over the entire circumference of the groove 160. The first locking surface 151, the slide surface 152, and the second locking surface 153 are inclined at a predetermined angle with respect to the circumferential direction of the water discharger 120C.

  Moreover, the outer cylinder part 220C with which the water sprinkling part 3C which concerns on 2nd Embodiment is provided is provided with the projection part 224 as a displacement mechanism. The protruding portion 224 protrudes from the inner peripheral surface of the outer cylindrical portion 220C into the groove 160, and a step portion between the first locking surface 151 and the slide surface 152 or the second locking surface 153. It is latched by the level | step-difference part between the 1st latching surfaces 151. FIG.

  The displacement mechanism according to the second embodiment is configured as described above. As shown in FIG. 9, the protrusion 224 is disposed between the second locking surface 153 and the first locking surface 151. By engaging with the step portion, the water spray plate 210 can be displaced to a separation position separated from the packing 400 (see FIG. 2). Further, the water spray plate 210 can be displaced to the abutting position where it abuts the packing 400 by engaging the protrusion 224 with the stepped portion between the first engaging surface 151 and the slide surface 152.

  When such a displacement mechanism is employed, the user can switch between “normal shower water discharge” and “high-speed shower water discharge” by pushing up and rotating the water sprinkling portion 3C.

  For example, in FIG. 9, the projecting portion 224 is in a state of being locked to a step portion between the second locking surface 153 and the first locking surface 151. In this state, when the user pushes up the water sprinkling part 3C, the state in which the protruding part 224 is locked to the stepped part is released. Further, when the user rotates the water sprinkling part 3 </ b> C clockwise, the protrusion 224 is locked to the stepped portion between the first locking surface 151 and the slide surface 152. Thereby, the user can switch shower water discharge from normal shower water discharge to high-speed shower water discharge.

  Further, when the user pushes up the water sprinkling part 3 </ b> C at the time of high-speed shower water discharge, the state where the protrusion 224 is locked to the stepped portion between the first locking surface 151 and the slide surface 152 is released. Further, when the user rotates the water sprinkling part 3C clockwise, the protrusion 224 moves along the slide surface 152, and the step portion between the second locking surface 153 and the first locking surface 151 is moved. It will be in the state where it was depressed and stopped. Thereby, the user can switch shower water discharge from high-speed shower water discharge to normal shower water discharge.

  Thus, the water discharging apparatus 1 may be provided with the level | step-shaped latching | locking part 150 and the projection part 224 as a displacement mechanism. In such a case, the protruding portion 224 is locked to the step portion between the first locking surface 151 and the slide surface 152 or the step portion between the second locking surface 153 and the first locking surface 151. Thus, the water spray plate 210 can be displaced.

  In addition, although the example of operation in the case of rotating watering part 3C clockwise here was shown, the user may rotate watering part 3C counterclockwise. In this case, the user rotates the water sprinkling part 3C counterclockwise in a state where the protrusion 224 is locked to the stepped portion between the first locking surface 151 and the slide surface 152, It is possible to switch to “normal shower water discharge”. That is, the operation of pushing up the watering part 3C becomes unnecessary. Further, for example, by providing a radius at a step portion between the slide surface 152 and the second locking surface 153, the protrusion 224 from the second locking surface 153 to the first locking surface 151 is provided. You may comprise so that a movement may be performed only by rotating the water sprinkling part 3C counterclockwise. This eliminates the need to push up the sprinkler 3C even when switching to “high-speed shower water discharge”.

  Although not shown here, a seal member 300 (see FIG. 2) is provided between the water discharge portion 120C and the outer cylinder portion 220C. The seal member 300 allows the outer cylinder portion 220C and the water discharge to be discharged. Watertightness with the part 120C is ensured. Further, the stepped locking portion 150 and the projection 224 as the displacement mechanism are provided above the seal member 300 (on the head main body 110 side). For this reason, the displacement mechanism is unlikely to affect the water tightness between the water discharger 120C and the outer cylinder 220C.

  As the displacement mechanism, a knock cam mechanism used for a knock ballpoint pen or the like can also be used. In such a case, the user can switch between normal shower water discharge and high-speed shower water discharge simply by pushing up the watering part.

(Third embodiment)
Next, a third embodiment will be described. In the third embodiment, a modification of the packing will be described with reference to FIG. FIG. 10 is a view showing a modification of the packing.

  As shown in FIG. 10, the packing 400 </ b> A according to the third embodiment is arranged side by side on the outer peripheral side with a part of the water sprinkling holes 212 arranged side by side on the inner peripheral side among the plurality of water sprinkling holes 212 and 213. Each of the sprinkling holes 213 has a ring shape facing each other. As a result, the sprinkling plate 210 is displaced to the contact position, so that, of the sprinkling holes 212 and 213, a part of the sprinkling hole 212 and a part of the sprinkling hole 213 are blocked by the packing 400A.

  In this way, the water spray holes 212 arranged side by side on the inner peripheral side and the water sprinkle holes 213 arranged side by side on the outer peripheral side are partially blocked by the packing 400A, respectively, thereby enabling “normal shower water discharge” and “high speed It is possible to prevent the shower water discharge range from changing as much as possible.

  Further, the packing 400A shown in FIG. 10 has a ring shape in which portions facing the plurality of water spray holes 212 and portions facing the plurality of water spray holes 213 are alternately provided. By setting it as such a shape, the water discharge range of a shower can be continued without interruption over the perimeter of the water spray plate 210.

  Here, an example in which the packing 400A is a single member has been shown. However, the packing 400A includes, for example, a part that closes the water spray hole 212 on the inner peripheral side and a part that closes the water spray hole 213 on the outer peripheral side. It may be divided into

(Fourth embodiment)
Next, a fourth embodiment will be described. In the fourth embodiment, a modification of the packing mounting structure will be described with reference to FIGS. FIGS. 11-13 is a figure which shows the 1st modification-3rd modification of the attachment structure of packing, respectively.

  For example, as shown in FIG. 11, the water discharger 120 </ b> D includes a substantially cylindrical fixing portion 126 that protrudes from the peripheral edge of the first water discharge port 121 toward the water spray plate 210. A claw 127 for locking a movable part 420 described later is provided at the tip of the fixed part 126. In addition, the water discharge part 120D, the fixing | fixed part 126, and the nail | claw 127 are integrally formed.

  A substantially cylindrical movable portion 420 and a coil spring 430 as an urging member are loosely fitted to the fixed portion 126. The movable part 420 is disposed closer to the water spray plate 210 than the coil spring 430, and is biased toward the water spray plate 210 by the coil spring 430. In addition, the movable portion 420 is locked to the claw 127 of the fixed portion 126, so that the movement toward the watering plate 210 is restricted. The packing 400 </ b> B is fixed to the distal end surface of the movable portion 420, so that the packing 400 </ b> B is opposed to the water spray hole 212.

  When the water spray plate 210 is displaced to the contact position with the packing 400B by the displacement mechanism, the packing 400B and the movable portion 420 are pushed up to the head main body 110 (see FIG. 2) side by the water spray plate 210, thereby engaging with the claw 127. The stopped state is released. As a result, the packing 400B and the movable portion 420 are pressed against the water spray plate 210 by the biasing force from the coil spring 430.

  In this manner, by attaching the packing 400B to the water discharger 120D via the coil spring 430, the state where the water spray holes 212 are blocked by the packing 400B can be firmly maintained, and the water from the packing 400B to the water spray holes 212 can be maintained. Leakage can be prevented. The mounting structure according to the first modification employs a displacement mechanism that requires an operation to displace the water sprinkling part 3C further to the water discharger part 120C than the contact position, such as the displacement mechanism shown in FIG. It is suitable when doing.

  Moreover, not only the example mentioned above but packing may be directly attached with respect to the water discharging part. For example, as shown in FIG. 12, the packing 400 </ b> C may be attached to the fixing portion 128 that is integrally formed with the water discharge portion 120 </ b> E. The fixing portion 128 is a substantially cylindrical portion that protrudes from the peripheral edge of the first water outlet 121 toward the water spray plate 210.

  12 shows an example in which the fixing portion 128 of the packing 400C is disposed on the inner peripheral side of the packing 400C, the fixing portion of the packing may be disposed on the outer peripheral side of the packing. For example, as shown in FIG. 13, the packing 400 </ b> D may be attached to a fixing portion 129 that is integrally formed with the water discharging portion 120 </ b> F. The fixing portion 129 is a substantially cylindrical portion that protrudes from the outer edge portion of the water discharging portion 120F toward the water spray plate 210 side.

  Thus, the packing may be directly attached to the water discharger. Thereby, the number of parts of the water discharging apparatus main body 2 can be reduced.

(Other embodiments)
In the above-described embodiment, the water discharge device that can adjust the temperature and the flow rate and can switch between the raw water and the purified water has been described as an example. The structure in which only one of switching with purified water is possible may be sufficient.

  Moreover, in embodiment mentioned above, although the water discharging apparatus installed in the counter of a kitchen or a bathroom vanity was mentioned as an example, the water discharging apparatus may be installed in a bathroom, for example.

  Moreover, in embodiment mentioned above, although the water discharging apparatus which can switch between shower water discharging and straight water discharging was mentioned as an example, the water discharging apparatus should just have the structure which can at least shower water discharging.

  In the above-described embodiment, an example in which a plurality of water spray holes are provided concentrically is shown. However, the arrangement of the water spray holes does not necessarily need to be concentric.

  Further effects and modifications can be easily derived by those skilled in the art. Thus, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications can be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
