Description

  The present invention relates to a water discharge switching structure of a shower head for switching between two or more types of water discharge.

  Conventional shower heads are known to be capable of discharging various types of showers, such as massage showers with slightly large water droplets, and soft showers with fine water droplets, in addition to normal shower water discharge. Yes. Such a shower head incorporates therein a water discharge switching structure for switching these water discharge modes. Such a conventional water discharge switching structure will be described with reference to FIG. 9, FIG. 10, and FIG.

  As shown in FIG. 9, the shower head 82 using the water discharge switching structure 80 performs three forms of water discharge, such as concentrated water discharge, straight water spray, and diffused shower water spray. Are provided with three operation sections A, B, and C for switching the above-described three types of water discharge. Further, as shown in FIG. 11, the shower head 82 is provided with valve openings 84a, 84b, 84c provided for the respective water discharge modes, and also opens and closes the valve openings 84a, 84b, 84c. Two valve devices 86 are provided. The valve device 86 includes an arm 92 pivotably mounted in the inflow path 88 via a pin 90 and a valve body provided at the tip of the arm 92 and biased in the direction of the valve seat 96 by a spring 94. And a valve case 100 that accommodates 98. Further, the support arm 102 is configured to be swung inward of the shower head 82 with the pin 90 as a fulcrum when the operation portions A and C are pushed. Further, the engaging arm 104 is configured to swing in the direction of the valve seat 96 with the pin 90 as a fulcrum through the protrusions 106 and 108 by the pushing operation of the operation portion B.

  Then, when the operation portion B is pushed in, the engagement arm 104 is pressed against the inner wall surface on the proximal end side of the protruding portion 112 in the elongated hole 110 and swings, and the valve device 86 swings around the pin 90 as a fulcrum. The valve port 84a is closed by the valve device 86 on the operation unit A side, the valve port 84c is closed by the valve device 86 on the operation unit C side, and the valve port 84b is opened. Thereby, the operation parts A and C connected by the pin 114 move in the protruding direction. When the operation part C is pushed in, the valve device 86 on the operation part C side attached to the insertion part 116 is swung to open the valve port 84c and close the valve port 84b. At this time, the projecting portion 112 of the operation portion B is pushed by the engagement arm 104 of the valve device 86 on the operation portion C side, and the operation portion B moves toward the distal end of the shower head 82. When the operation unit A is pushed in from the state in which the operation unit C is pushed in, the valve device 86 on the operation unit A side is swung through the insertion portion 116 to open the valve port 84a and open the valve port 84b. Is blocked. At this time, the valve case 100 of the valve device 86 on the operation unit C side is pushed by the valve case 100 of the valve device 86 on the operation unit A side, and the valve device 86 on the operation unit C side closes the valve port 84c. Rocks. As a result, the operation unit C moves in the protruding direction via the insertion unit 116. In this way, any one of the valve ports 84a, 84b, and 84c is opened by the push operation of each operation unit, and each water discharge form is selected.

  Further, as shown in FIG. 10, the valve body 98 accommodated in the valve case 100 is urged toward the valve port 84 by a spring 94 so that each valve port 84 can be reliably closed. Moved. Therefore, in order to enable smooth movement on the valve seat 96, the valve body 98 is formed in a spherical shape, and is provided so as to be smoothly moved on the valve seat 96 when the valve body 98 rolls appropriately. Yes. Further, since the valve body 98 is formed in a spherical shape, and thus the valve body 98 rolls with movement, a certain part of the valve body 98 does not always become a seal portion that closes the valve port 84. Therefore, it is necessary to be able to remove burrs or the like by polishing over the entire outer peripheral surface so that the valve port 84 can be reliably sealed regardless of the part where the valve body 98 closes the valve port 84. there were. Further, although the spring 94 is attached to the valve body 98, since the valve body 98 is provided to roll as described above, the portion of the valve body 98 that contacts the spring 94 is not constant. Therefore, the spring 94 may be damaged over the entire outer peripheral surface of the valve body 98. Therefore, a metal ball valve such as SUS is used as the valve body 98 in order to easily remove burrs and the like on the entire outer peripheral surface and prevent the entire outer peripheral surface from being easily damaged (for example, (See Patent Document 1).

Japanese Patent Laid-Open No. 2002-21132 (FIGS. 1, 4, 6, and 7)

  However, the above-described conventional water discharge switching structure 80 has the following problems. In this water discharge switching structure 80, since the total area of the water discharge ports and water spray holes corresponding to each water discharge form is different for each water discharge form, and the water discharge flow rate is different depending on the water discharge form, the valve device 86 in the flow path is different for each water discharge form. The water pressure applied to is different. For example, the water pressure in the shower head 82 is low when water is discharged from a concentrated water outlet with a large flow rate, and is high when shower water is sprayed at a small flow rate. On the other hand, in the conventional water discharge switching structure 80, since the valve device 86 is shared to close each valve port 84, the same spring 94 is used for a plurality of valve ports 84 corresponding to different water discharge forms. Thus, the valve body 98 is biased to the plurality of valve openings 84 with the same load. Therefore, the weight of the operation feeling of the operation units A, B, and C when switching from one water discharge form to another is different depending on the type of water discharge form, and the operation feeling of the operation parts A, B, and C is the same. It was difficult to make. Further, in the conventional water discharge switching structure 80 described above, since the two valve bodies 98 must be moved at the same time, the operational feeling becomes heavy and the operability is deteriorated. In particular, since a metal ball valve is used as the valve body 98 in order to secure the seal portion, the water discharge mode switching operation which is performed by moving the valve body 98 becomes heavier.

  The present invention eliminates the problems of the conventional showerhead water discharge switching structure described above, reduces the operability of the operation unit, and does not change the operational feeling of the operation unit depending on the water discharge mode in the switching operation. An object is to improve the operability of the operation unit. Further, in the water discharge switching structure according to the second aspect of the present invention, it is also an object to make the operation feeling lighter by making the valve body made of resin.

  In order to solve the above problems, means taken by the present invention will be described below. The shower head water discharge switching structure of the present invention is “a shower head water discharge form switching structure capable of discharging water in two or more water discharge forms by operation of the operation portion, and a number of valve bodies corresponding to the number of water discharge forms. And a valve port, the valve body being pressure-bonded to the valve port and closing the valve port, and an inclined outer peripheral part connected to the inclined outer peripheral part and held on the shower head main body side And a water discharge switching structure for a shower head, wherein the inclined outer peripheral portion is provided so as to reciprocate in a substantially vertical direction with respect to the valve port to open and close the valve port. Item 1).

In the present invention, as described above, as many valve bodies and valve openings as the number of water discharge forms are provided.
Therefore, it is only necessary to open and close the valve opening by the valve body provided for each valve opening, and it is not necessary to provide a plurality of valve openings to be opened and closed by the same valve body. Therefore, since it is only necessary to operate one valve body in the operation at the time of selection of each water discharge form, the operation feeling of an operation part can be made light. Moreover, since it is only necessary to move the valve body corresponding to each water discharge form and open the valve opening for each water discharge form, even if the water pressure in the shower head is different for each water discharge form, it is different. If a different load is set on each valve body and it is energized by a spring, etc., such as using springs with different elasticity depending on water pressure, the weight of operation at the time of switching the water discharge mode can be made the same it can.

  In addition, since the valve body does not need to move between the valve ports, it is not necessary to use a spherical valve body. Therefore, in the present invention, a valve body including an “inclined outer peripheral portion” that is crimped to the valve opening and a “held portion” that is held on the shower head main body side is used. Only the `` inclined outer periphery '' is used as a seal part so as to securely close the mouth. On the other hand, a spring is attached to the part of the `` held part '' to urge the valve body or As a configuration such as support, a “held part” that is not used as a seal part is provided on the valve body. In addition, the “inclined outer peripheral portion” is configured to reciprocate in a substantially vertical direction with respect to the opening of the valve opening to open and close the valve opening. By configuring in this way, it is only necessary to perform processing such as molding and polishing so as to ensure sealing performance only at the `` inclined outer peripheral part '', and it is not necessary to ensure sealing performance at the `` held part '', Ensuring the sealing performance of the valve body used in such a switching structure can be facilitated. In addition, since it is not necessary to secure a seal part over the entire outer peripheral surface, it is easy to make a valve body made of resin, etc. by extrusion molding, etc. The feeling can be lightened. The “inclined outer peripheral portion” can be exemplified by a portion where an inclined surface inclined toward the center of the valve port is provided in a circumferential shape, a portion which is inclined while being gently curved in a slightly arc shape, and the like. The “held part” includes all parts supported on the shower head main body side. For example, a cylindrical part, a columnar part, a prismatic part, or a plate connected to the “inclined outer peripheral part” described above. Various shapes such as a shape portion are included.

  Further, in the water discharge switching structure, the inclined outer peripheral portion of the valve body may be a spherical portion, and the held portion may be a cylindrical portion (Claim 2).

  Such a cylindrical held portion can be accommodated and held in a cylindrical holding portion or the like provided on the shower head main body side, and the valve port can be closed by a spherical portion on the tip side thereof, so that a simple shape can be obtained. The valve body can be moved stably and easily by the substantially bullet-shaped valve body.

  In any one of the water discharge switching structures, the valve body may be made of resin.

  As described above, since the seal portion only needs to be provided on a part of the valve body, the seal portion can be easily secured even as a resin valve body by extrusion molding or the like. And by making a valve body resin, the operation feeling of the operation part which moves this can be made lighter than the case of metal valve bodies. The resin includes various resins such as a synthetic resin such as POM and ABS, and a natural resin.

  Since the present invention is configured as described above, it is possible to improve the operability of the operation unit by reducing the operability of the operation unit and making the operation feeling of the operation unit different depending on the water discharge form in the switching operation. Can do.

  Next, an embodiment of the water discharge switching structure for a shower head according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the shower head water discharge switching structure 12 of the present invention is provided in the head portion 3 of the shower head 1 into which hot water and water flow from a hose (not shown), and is attached to the lower surface of the head portion 3. The water discharged from each of the water spraying portions 7, 9, 11 of the water spray plate 5 is switched. A first watering part 7 is provided at the center of the watering plate 5, a second watering part 9 is provided on the outer side, and a third watering part 11 is provided on the outer side, and large water droplets are discharged from the first watering part 7. The massage shower is a slightly larger hard shower from the second sprinkler 9 and a soft shower of fine water droplets is discharged from the third sprinkler 11. In the present shower head 1, the handle 57 is swung around the water spray plate 5, and when a hard shower is swung to the left in a plan view when viewed from the front end of the shower head 1, a soft shower is performed. When a swing operation is performed on the right side in a plan view when viewed from the front end direction of the shower head 1, a massage shower is discharged. FIG. 1 shows a state in which a massage shower is discharged from the first watering part 7.

  As shown in FIGS. 2 and 3, a connection portion 13 protrudes from the inside of the grip portion 4 into the head portion 3, and hot water / water flows from the connection portion 13. The connection portion 13 is inserted into a connection port 16 formed in the main body 15 in the head portion 3. The main body 15 is formed in a bottomed cylindrical shape having a bottom portion 17 on the upper side of the head portion 3, and the bottom portion 17 is positioned above each valve port 53 a, 53 b, 53 c on a switching plate 51 described later. Three bottomed cylindrical valve body accommodating portions 19a, 19b, and 19c are formed in each of the portions to be performed. In the valve body accommodating portion 19, a notch 21 into which an arm portion 33 of later-described valve bodies 27a, 27b, and 27c can be inserted is formed at an opposing position across the axis, and each valve body 27 is The arm portion 33 is inserted into the notch 21 and is held and held in each valve body storage portion 19 in a state where the arm portion 33 can reciprocate up and down. In addition, an annular circumferential groove 23 is recessed in the bottom of the valve body housing portion 19, and springs 25 a, 25 b, 25 c held in the annular circumferential groove 23 urge the valve body 27 toward the valve port 53. Yes.

  These springs 25 are used in which the load is set according to the water pressure in the main body 15 in each of the three types of water discharge. For example, when a soft shower is discharged in a state in which a predetermined amount of the valve opening of the faucet body is opened by the operation handle of the faucet body and hot water or water is supplied to the shower head 1 side, Since the total area of the water spray holes opened in 11 is relatively large and the amount of water discharged increases, the water pressure in the main body 15 becomes lower. On the other hand, when the hard shower is discharged, the total area of the sprinkling holes of the second sprinkling section 9 is smaller than the total area of the sprinkling holes of the third sprinkling section 11, and the water discharge amount is reduced. Become higher. Therefore, when switching from the soft shower to the hard shower, the water pressure applied to the valve body 27b increases, and a stronger force is required to separate the valve body 27b from the valve port 53b. For this reason, when switching to the hard shower, the load applied to the valve body 27b of the spring 25b attached to the valve body 27b is applied to the valve body 27a of the spring 25a in order to prevent the feeling of operation of the handle 57 from becoming heavy. The load is weaker than the applied load, and the weight of the operation feeling of the handle 57 at the time of switching the water discharge mode is made the same. Similarly, the load is also varied for the spring 25c attached to the valve body 27c moved during the massage shower. In this example, the springs 25a, 25b, and 25c having different elasticity are used for the respective valve bodies 27 in order to make the loads different, but the valve body accommodating portions that accommodate the springs 25a, 25b, and 25c, respectively. The 19 strokes may be different.

  Next, the POM valve body 27 will be described. As shown in FIG. 5, the valve body 27 includes a spherical portion 29 in the lower portion, and a cylindrical portion 31 is continuously provided above the spherical portion 29 so that the entire valve body 27 is formed in a substantially bullet-like shape. A cylindrical arm portion 33 projecting in the radial direction is provided at a position facing the axis of the cylindrical portion 31. The cylindrical portion 31 is provided with an outer diameter slightly smaller than the inner diameter of the valve body housing portion 19, and the cylindrical portion 31 moves up and down along the axial direction in the valve body housing portion 19. Further, as described above, the arm portion 33 is inserted into the notch 21 of the valve body housing portion 19 so as to be reciprocally movable up and down, and the valve body 27 is held in a predetermined direction around the axis of the cylindrical portion 31. It is configured as follows. Further, the arm portion 33 is formed to have a diameter slightly smaller than the width of the notch 21, and is configured so that the valve body 27 can reciprocate smoothly and stably in the notch 21. Further, an annular housing groove 35 in which the spring 25 is housed and held is provided from the upper surface of the cylindrical portion 31 downward. The spherical portion 29 is pressure-bonded to the valve port and used as a seal portion. The cylindrical portion 31 corresponds to the “held portion” referred to in the present invention. In this way, since the valve body 27 is always pressure-bonded to the valve port 53 with the spherical portion 29 of the same part as the seal portion, only the spherical portion 29 is appropriately processed as the seal portion. For example, the cylindrical portion 31 that is the held portion does not cause a problem in the reliable closing of the valve port 53 even if some burr or the like is generated. Further, the valve body 27 is made of resin, and when the water discharge mode is switched, it is only necessary to separate one valve body 27 from the valve port 53, so that the operational feeling can be lightened. The valve body 27 may be made of other resin such as ABS. Moreover, the manufacturing cost of the valve body 27 can also be reduced by using resin.

  Next, a pendulum member 37 that opens and closes the valve port 53 by reciprocating the valve body 27 in a substantially vertical direction with respect to the valve port 53 will be described. As shown in FIGS. 4 and 6, the pendulum member 37 is attached to a handle 57 which will be described later, and is provided so as to be swingable along the site where the three valve ports 53 are disposed. On one end side of the pendulum member 37, a fitting convex portion 39 is formed so as to project upward, in which a parallel surface to be fitted into the fitting concave portion 65 on the handle 57 side is formed. Further, on the side opposite to the fitting convex portion 39, a cylindrical portion 40 that protrudes and accommodates in a cylindrical accommodating concave portion 52 of the switching plate 51 is projected. A support portion 41 that supports the valve element 27 is provided on the other end side. The support portion 41 is provided with two support pieces 43 that are erected at a distance slightly larger than the outer diameter of the cylindrical portion 31 of the valve body 27. The support piece 43 is erected substantially along a direction orthogonal to the longitudinal direction of the pendulum member 37, and is erected in an arc shape having the fitting convex portion 39 side as a swing axis. In the vicinity of the center of the upper end portion of each support piece 43, a locking recess 45 is provided to lock the arm portion 33 of the valve body 27 that rides on the upper end portion of the support piece 43, and the valve supported by the support piece 43. It is comprised so that the body 27 can be supported stably. Further, the support piece 43 is formed so that both ends thereof are slightly lowered and are configured to smoothly scoop up the arm portion 33 of the valve element 27 onto the support portion 33 by a swinging pendulum member 37. In addition, the main portion 47 of the support portion 41 is provided with an opening 49 that communicates with the valve port 53 when the main portion 47 is positioned on each valve port 53.

  Next, the switching plate 51 will be described. As shown in FIGS. 2 and 3, the switching plate 51 is disposed below the main body 15 and the pendulum member 37, is attached along the inner peripheral surface of the main body 15, and has a substantially cylindrical shape. As described above, the cylindrical portion 40 of the pendulum member 37 is swingably received and held on the upper surface of the switching plate 51, and the receiving recess 52 serving as the swing shaft of the pendulum member 37 is recessed. In addition, three valve ports 53 are opened on an arc on the upper surface of the switching plate 51 with the accommodating recess 52 as an axis. Further, each of these valve ports 53 is provided at a portion located directly below each valve body 27. Each of the valve ports 53a, 53b, and 53c communicates with flow paths 55a, 55b, 55c formed in the switching plate 51 in isolation.

  Next, the handle 57 as an example of the “operation unit” according to the present invention will be described. As shown in FIGS. 4 and 6, the handle 57 is swingably attached between the periphery of the water spray plate 5 and the main body 15 of the head portion 3 and the head cover 4 of the head portion 3. This is a member for swinging the pendulum member 37 along the three valve ports 53 to switch the three water discharge modes. The handle 57 has a cylindrical portion 59 that is mounted around the water spray plate 5 and is slidable within a predetermined range around the water spray plate 5, and an outer periphery of the cylindrical portion 59 so that the user can swing the handle 57. An operation projecting piece 61 projecting from the surface and a swinging projecting piece 63 projecting from a part of the cylindrical portion 59 obliquely upward to the axial center of the cylindrical portion 59 are provided.

  The operating protrusion 61 is mounted on the head portion 3 so as to be swingable, and its tip is positioned on the fitting convex portion 39 of the pendulum member 37. A fitting recess 65 into which the portion 39 is fitted is provided. Then, as shown in FIGS. 4 and 6, by swinging the operation protrusion 61, the cylindrical portion 59 is rotated around the water spray plate 5, and the swing protrusion 63 is swung accordingly. The pendulum member 37 fitted in the fitting recess 65 is swung along the three valve ports 53 on the switching plate 51, and one of the valve bodies 27 is opened by the support piece 43 of the pendulum member 37. And each water discharge form is selected. In this way, the handle 57 integrally constitutes the appearance of the head portion 3 together with the head cover 4 and the water spray plate 5 and only one operation protrusion 61 protrudes from the head portion 3. Compared with a shower head or the like provided with the same number of operation buttons as the number of forms, the shower head 1 can be neatly organized and have a good appearance. In addition, since the water discharge mode can be switched only by operating one operation protrusion 61, the operability is also good. Particularly, in a shower head that has three or more water discharge modes and the selection of the water discharge mode is likely to be complicated. Is preferred.

  As shown in FIGS. 2 and 3, a diversion plate 66 is attached below the switching plate 51, and a watering plate 5 is further attached. In the switching plate 51, as described above, the flow paths 55a, b, and c are provided, respectively, but each of the flow paths 55 constitutes the water spray plate 5 and performs three water discharge modes. The first watering part 7, the second watering part 9, and the third watering part 11 communicate with each other. The water spray plate 5 has a cylindrical first shower face 67 having a cylindrical shape with a first sprinkler 7 in the center and a second sprinkler 9 around the first sprinkler 7. The shower face 67 is mounted in the opening and is assembled to the inside of the handle 57, and is composed of a second shower face 69 provided with the third water sprinkling portion 11.

  In the shower head 1 configured as described above, three water discharge modes can be performed by swinging the handle 57 as described above. FIG. 2 shows a state in which a hard shower from the second water sprinkling unit 9 is selected. The pendulum member 37 is swung below the central valve body 27b, and the support piece 43 resists the urging force of the spring 25b. However, the arm portion 33 of the valve body 27b is lifted to the back side of the valve body housing portion 19, and the spherical portion 29 is separated from the valve port 53b. In this state, the flow path in the main body 15 communicates with the valve port 53 b, and water is discharged from the second water sprinkling unit 9 through the flow path 55 b in the switching plate 51. FIG. 3 shows a state in which a soft shower from the first sprinkler 7 is selected, and the pendulum member 37 is swung below the valve body 27a, and the valve body 27a is lifted in the same manner as described above to obtain a spherical shape. Water is discharged from the first water sprinkling unit 7 by separating the part 29 from the valve port 53a. In addition, although illustration is abbreviate | omitted, also when performing a massage shower, the valve body 27c is similarly lifted by the pendulum member 37, and the water discharge from the 3rd water sprinkling part 11 is performed.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, in the present embodiment, the “held portion” of the valve body 27 is formed in a cylindrical shape, but is not limited to this, for example, it is formed in a prismatic shape or a plate shape, or the arm portion in the present embodiment. As shown in FIG. 33, various members can be formed in such a manner as to be held on the main body 15 side, such as by projecting a member held on the main body 15 side of the shower head 1. In addition, the “inclined outer peripheral portion” referred to in the present invention is a substantially hemispherical spherical surface portion 29 in the above-described embodiment, but is not limited to this, and for example, as shown in FIG. It may be a cut inclined surface 70, or may be a semi-ellipsoid inclined surface 72 as shown in FIG. Furthermore, the inclined outer peripheral portion may be constituted by the cone itself, or may have a shape including only a part of the ellipsoid as well as a half of the ellipsoid. As described above, the “inclined outer peripheral portion” to be pressure-bonded to the valve port 53 can have various shapes. Moreover, in the above-mentioned shower head 1, the three water discharge modes are switched, but another number of water discharge modes may be switched. In addition, the valve body 27 is not limited to the pendulum member 37, and each valve body 27 may be separated from or close to the valve port 53 by other means. For example, the valve body 27 may be electrically driven using a solenoid. it can. The valve body 27 is attached so as to be biased in a direction away from the valve port 53 in the direction opposite to the spring 25, and the valve body 27 is pressed against the valve port 53 against the urging force of the spring. It is good also as a structure which cancels | releases a crimping | compression-bonding state and separates the valve body 27 from a valve opening with a spring.
