Description

Shower

The present disclosure relates to a shower device having a shower surface and a water spraying surface formed on a shower head for spraying water in a direction different from the direction in which water is sprayed from the shower surface.

In the past, shower heads capable of performing multiple types of water sprinkling and spraying have been proposed. Patent document 1 discloses a multifunctional shower device in which a shower head is provided with two types of water spray holes having different flow paths.

Thus, by providing different types of water sprinkling holes in the shower head, the shower can be used for various purposes. For example, if there are two water spouting surfaces with different water sprinkling directions, one surface can be used for body showering, and the other surface can be used for other purposes such as bathroom washing.

In recent years, many shower devices with multiple water spraying surfaces have been tried and proposed. By providing a switch setting lever (setting operation unit), two types of water spraying can be easily switched by operating the lever. [Prior technical literature] [Patent literature]

[Problems to be solved by the invention]

However, even if the body shower and other-purpose water jets can be easily switched, for people who are not familiar with such shower devices, it may be difficult to predict the spraying location, spraying direction, and spraying water strength of the other-purpose water jets, and they may be frightened by unexpected water jets.

In summary, when a shower head is provided with a water spraying surface different from the shower surface, it is required that the user does not feel panicked by unexpected water spraying from the water spraying surface, that is, the user can easily understand the specific specifications and usage of the water spraying surface.

This disclosure is made in consideration of this situation, and aims to provide a shower device that allows users to easily understand the specifications and usage of spraying water from a spray surface that is different from the shower surface. [Means for solving the problem]

To achieve the above-mentioned purpose, the shower device disclosed in the present invention has a shower surface and a water spraying surface on the shower head that sprays water in a direction different from the direction of water spraying from the shower surface. The water spraying from the water spraying surface includes the water spraying for other purposes other than body use according to a predetermined water level. The shower device has a setting operation unit and a water spraying operation unit. The setting operation unit can be switched to spray water from the shower surface. The bathing surface is sprayed with water and the water is sprayed from the spraying surface; the spraying operation part is operated to perform the other purpose spraying when the setting operation part is used to set the water spraying from the spraying surface; when the faucet is turned on and the setting operation part is used to set the water spraying from the spraying surface, when the water spraying operation part is not operated, the water is sprayed with a water force weaker than the water force of the other purpose spraying.

The shower device disclosed in the present invention may also be equipped with two or more structures that can be selected from the following structures (1) to (3) and can be combined. Structure (1): The water spraying operation part is a momentary switch. Structure (2): The water spraying surface is provided at the front end of the shower head and can spray water in a direction orthogonal to the direction of water spraying from the shower surface. Structure (3): The flow path inside the shower head to the water spraying surface is divided into a general flow path for strong water spraying and a drainage flow path for weak water spraying. [Effect of the invention]

Since the shower device disclosed in the present invention has the aforementioned structure, the user can easily understand the specifications and usage of the water spraying surface which is different from the shower surface.

[Form used to implement the invention]

The following is a description of the embodiment of the present disclosure with reference to the attached drawings. First, the basic structure of the shower device 1 of the present embodiment is described. In addition, in this specification and the scope of the present patent application, spraying water from the shower surface s1 is a type of water spraying, and in order to distinguish it from spraying water from the water spraying surface s2, it is described as "sprinkling water".

The shower device 1 has a shower surface s1 and a water spray surface s2 that sprays water in a direction different from the direction of water sprayed from the shower surface s1 formed on a shower head 2. The water spraying from the water spray surface s2 includes the water spraying for other purposes other than body spraying according to a predetermined water level.

The shower device 1 has a setting operation unit 8 that can switch between spraying water from the shower surface s1 and spraying water from the spray surface s2. In addition, the shower device 1 has a water spraying operation unit 10 that can be operated to spray water for other purposes when the setting operation unit 8 is set to spray water from the spray surface s2.

When the faucet is turned on and the setting operation unit 8 is set to spray water from the water spray surface s2, the shower device 1 sprays water at a water force weaker than that of other purpose sprays when the water spray operation unit 10 is not operated.

Here, the predetermined water level does not refer to a specified value. If other uses are such as bathroom cleaning described later, a water level stronger than the shower surface s1 is ideal. Also, if it is used for purposes other than bathroom cleaning, a water level corresponding to such purpose is ideal.

Next, the detailed structure of the shower device 1 will be described with reference to Fig. 1 to Fig. 6. The water jet for other purposes is a water jet for cleaning the bathroom in this embodiment, but it can also be used for purposes other than cleaning the bathroom.

The spray surface s2 of the cleaning water jet is provided at the front end of the shower head 2, and water is sprayed from the spray surface s2 in a direction approximately perpendicular to the direction of the water sprayed from the shower surface s1. In addition, the cleaning water jet is used to clean the walls or floors, drains, doors and window frames of the bathroom. Since the water force of the spray water removes dirt, it is preferably stronger than the water force of the water sprayed from the shower surface s1.

As shown in Fig. 1, the shower device 1 is formed by a shower head 2 having a head portion 2a and a handle portion 2b. A shower water pipe (not shown) is connected to an open end portion 2c of the handle portion 2b (a water pipe installation port 48a of an inflow portion 48 described later).

In addition, in this specification, the up and down directions are defined based on the front view of Fig. 1 (a). In addition, the front end (open end) side of the shower head 2 is defined as the front side, and the shower water pipe side is defined as the rear side.

As shown in Fig. 1 (a) (c), a shower surface s1 is formed on the lower surface of the head portion 2a of the shower head 2 and has a plurality of water sprinkling holes 77 therein for mainly sprinkling water toward the human body.

In addition, a water spraying surface s2 is formed on the side end surface of the head 2a opposite to the grip portion 2b (the side end surface on the front end side of the head 2a). A plurality of spraying holes 45a (see FIG. 2, etc.) are provided on the water spraying surface s2, and the faucet water flowing into the shower head 2 is sprayed toward the front end of the shower head 2 (in a direction approximately orthogonal to the direction of water spraying from the shower surface s1). This water spraying is mainly used for cleaning in the bathroom (removal of scale and mucus). Since the water spraying direction of the water spraying surface s2 is the direction extending along the longitudinal direction from the front end of the shower head 2, it is easy for the user to aim at the cleaning target when holding the grip portion 2b, and it is convenient to use.

1 (a) (c), a setting operation portion 8 that can be rotated along the circumference of the head 2a is provided near the grip portion 2b below the head 2a. The setting operation portion 8 is used to set a switching lever 8 for any one of the three modes of watering and spraying.

The setting of the switching lever 8 at the A position on the extension line of the grip portion 2b in the longitudinal direction (the state illustrated in FIG. 1(c)) is a setting for spraying water from the central portion s11 of the shower surface s1 (standard setting). The setting of the switching lever 8 at the B position in FIG. 1(c) is a setting for spraying water from the central portion s11 and the peripheral portion s12 of the shower surface s1 (full setting). The setting of the switching lever 8 at the C position in FIG. 1(c) is a setting for spraying water from the water spraying surface s2. The switching of the switching lever 8 is performed by rotating the switching lever 8 in the direction of the hollow arrow in FIG. 1(c).

As shown in Fig. 1 (a) (b), a slidable water spraying operating part (sliding rod) 10 is provided on the head 2a. The sliding rod 10 is an operating rod for turning on/off the water spraying for cleaning. When the faucet is turned on and the switching rod 8 is set to spray water from the water spraying surface s2, the water spraying for cleaning is performed when the sliding operation of the sliding rod 10 is performed (operation in the direction of the hollow arrow). Furthermore, when the faucet is turned on and the switching rod 8 is set to spray water from the water spraying surface s2, when the sliding operation is not performed, the water spraying is performed with a water force weaker than the water force of the water spraying for cleaning.

In this embodiment, "sliding operation is performed" means that the slide bar 10 is in the open position (the limit position on the left side of Figure 1 (a)). No sliding operation is performed means that the slide bar is in the closed position (a position other than the limit position on the left side of Figure 1 (a)). The limit position on the right side of Figure 1 (a) is the pre-position of the slide bar. When the slide bar is in this position or before reaching the limit position on the left side, it cannot be said that the sliding operation is performed, and the cleaning water spray is in the closed state.

Thus, when the slide lever 10 is not in the open position, water does not stop spraying from the water spraying surface for 2s, but a small amount of water (thin stream of water) is sprayed so that people can see the extent of the spraying. That is, the on/off operation of the slide lever 10 can also be called the strength operation of the water spraying.

In this embodiment, the slide rod 10 is a momentary switch, and only when the front end of the head 2a is pressed by a finger to the left limit position, water is sprayed from the water spray surface s2 for cleaning. When the hand leaves the slide rod 10, a thin stream of water is sprayed.

In this way, since the cleaning water jet is performed by the two-stage operation of the setting operation part 8 and the operation of the water jet operation part 10, there is almost no risk that the user will be frightened by the strong water force of the cleaning water jet.

If the switching lever 8 is set to spray water from the water spraying surface s2, the user may be startled by strong water from a place different from the shower surface s1, or by water spraying in an unexpected direction. However, the shower device 1 can avoid such a situation as much as possible. That is, according to the shower device 1, the user can easily understand the specification and usage of the water spraying from the water spraying surface s2 which is different from the shower surface s1 by seeing a small amount of water spraying from the water spraying surface s2. In addition, if the switching lever 8 is set to spray water from the shower surface s1 and the faucet is turned on, water will be sprayed from the shower surface s1 immediately.

In addition, the slide rod 10 can be fixed (locked) in the open position when the hand is released. In addition, the lock in the open position is preferably to temporarily close the faucet without unlocking it, and then open the faucet without spraying water with strong water force for cleaning. That is, it is ideal to have a mechanism that unlocks the faucet at the time of closing the faucet or setting the switching rod 8 to spray water from the shower surface s1.

FIG. 2 is an exploded perspective view of the shower head 2. FIG. 3 is a longitudinal cross-sectional view of the main part of the shower head 2 in the closed position (prepared state) of the sliding rod 10. FIG. 4 (a) is an exploded plan view of the parts (flow path block 20) inside the shower head 2, and FIG. 4 (b) is a perspective view (the direction in which the inside can be seen) of the parts (cleaning spray part 45) inside the shower head 2. Based on these figures, the parts inside the shower head 2 are explained.

The shower head 2 is roughly divided into a water spray operation part 10, a head housing 3, a flow channel block 20, a flow channel cover 15, a cleaning water spray part 45, an inflow part 48, a branch part 50, a branch part setting plate 60, a water passing plate 70, and a water sprinkling plate 75.

The head housing 3 is a housing that integrates the main body 4 and the handle peripheral portion 5. The shower surface s1 side that accommodates the main body 4 is open, and the handle peripheral portion 5 is a cylindrical body (refer to Figure 1 (c) and Figure 2).

A rod arrangement portion 4a in the form of a recess for arranging the sliding rod 10 is formed on the upper surface of the storage body 4, and a water spray opening 4c for forming a water spray surface s2 is opened on the side surface of the front end of the storage body 4. The rod arrangement portion 4a is formed to be longer than the sliding rod 10 so that the sliding rod 10 can slide between the closed position and the open position. A sliding opening 4b is opened in the middle of the length direction of the rod arrangement portion 4a, into which a rod holding portion 12 protruding from the bottom of the sliding rod 10 can be inserted and for which the rod holding portion 12 can slide.

The sliding lever 10 has a plate-like base, an operation protrusion 11 on the upper surface of the base, and the rod-shaped lever holding portion 12 on the lower surface. The lower end of the lever holding portion 12 is formed into a double fork shape so that it can hold the neck 35a of the switching lever 35 described later.

On the top surface side of the head housing 3, there are arranged a flow path block 20, a flow path cover 15 arranged on the upper surface side of the flow path block 20, a water spraying part 45 installed on the front end side of the flow path block 20, and an inflow part 48 installed on the rear end side of the flow path block 20. A water pipe installation port 48a is provided in the inflow part 48. The flow path cover 15 is provided with an insertion opening 15a through which the rod holding part 12 of the sliding rod 10 can be inserted.

The flow path block 20 is formed by a disc-shaped substrate portion 26 and a flow path portion 21 integrally provided thereon. The flow path portion 21 has an inflow path 21b separated by a U-shaped wall portion for the faucet water received through the inflow portion 48 to flow in. The faucet water enters from the inflow port 21a through the cylindrical inflow portion 48 and the end opening 21d, flows to the branch portion inlet 21c, and then flows out to the branch portion 50 described later.

In addition, the flow path portion 21 is formed with a rod arrangement portion 23 and a water spraying outflow path 22 as a flow path for water spraying from the water spraying surface s2. As shown in FIG4(a), the rod arrangement portion 23 is arranged between the bifurcated branch paths of the U-shaped inflow path 21b, and the outer peripheral portion 23a is formed to surround a space in which the switching rod 35 can be horizontally arranged. The lower part of the outer peripheral portion 23a is formed by the base plate portion 26. In addition, a circular hole 23b (see FIG3) is opened at the rear end of the outer peripheral portion 23a so that the switching rod 35 can slide.

The outer peripheral portion 23a opens upward in the middle of the length direction, and the middle opening 24 and its adjacent path (partitioned by one of the branching entrance walls of the inflow path 21b) form an L-shaped water spraying outflow path 22. In addition, a drainage hole 25 opened on the top surface of the outer peripheral portion 23a is provided on the upstream side (inflow portion 48) of the middle opening 24 interrupted by the outer peripheral portion 23a of the rod installation portion 23.

The inner space of the outer peripheral portion 23a of the rod arrangement portion 23 communicates with the opening of the return port 52 which is embedded in the embedding port 27 opened approximately in the center of the lower substrate portion 26. This return port 52 is a passage for the cleaning water to return to the water spraying outflow path 22 when the switching rod 8 is set to spray water from the water spraying surface s2.

As shown in FIG. 3 and FIG. 4( a ), a rod-shaped switching rod 35 with a coil spring 36 disposed on the front end side is disposed inside the rod arrangement portion 23. A neck portion 35a is formed at the rear portion of the switching rod 35, and the rod holding portion 12 of the slide rod 10 disposed on the upper side of the storage body portion 4 holds the neck portion 35a, thereby connecting the two components. A coil spring 36 is mounted on the front end side of the switching rod 35, and the other end of the front end side of the coil spring 36 is fixed to a coil spring fixing portion 41 of a fixing plate 40 mounted on the front end of the flow path block 20.

The switching rod 35 has a large diameter portion 35c on the downstream side and a small diameter portion 35b on the upstream side. A weir portion 35d having a gasket 35e and a larger diameter than the large diameter portion 35c is formed at the upstream end of the large diameter portion 35c. A rear weir portion 35f having a gasket 35g is formed on the upstream side of the small diameter portion 35b, and a rear end small diameter portion 35h having the neck portion 35a in the middle is formed behind it.

The switching rod 35 is in the rod installation portion 23. When the sliding rod 10 is pushed forward, the coil spring 36 is compressed and the switching rod 35 moves forward. When the sliding rod 10 is released by hand, the coil spring 36 elastically returns and the switching rod 35 moves to its original position at the rear.

Furthermore, an outflow port 42 for the cleaning water flowing out from the water spraying outflow path 22 of the flow path portion 21 is formed at a position adjacent to the coil spring fixing portion 41 of the fixing plate 40. A cleaning water spraying portion 45 is connected to the front portion of the fixing plate 40.

As shown in Fig. 2, Fig. 3 and Fig. 4(b), the cleaning water spraying part 45 is formed as a cover-shaped spraying part for spraying the cleaning water. The inlet side of the cleaning water spraying part 45 has an opening for installing the fixing plate 40 therein, and the outlet side is provided with a plurality of (five in the example) spraying holes 45a (refer to Fig. 2) for spraying the cleaning water. In addition, inside the cleaning water spraying part 45, a rectifying path 45c separated by a rib plate 45b is formed to lead to five spraying holes 45a individually. The diameter of the spraying hole 45a is preferably 0.7 mm to 1.4 mm, and the interval is preferably about 1 mm to 3 mm.

Furthermore, the flow of the cleaning water in the flow path section 21 is described in detail. In addition, the water flowing into the shower head 2 is controlled by the branch section 50 disposed below the flow path block 20 to flow as a shower surface s1 (standard shower or full shower) or as a spray surface s2. The branch control of the faucet water performed by this branch section 50 will be described later together with the description of the branch section 50.

As shown in FIGS. 2 to 4 , the cleaning water of the flow path portion 21 is generated by the water flowing into the inflow path 21b of the flow path portion 21 through the inflow portion 48, flowing to the lower branch portion 50 through the two branch portion inlets 21c, and then returning to the upper flow path portion 21 from the return port 52. This will be described in detail below with reference to FIGS. 3 to 5 .

The cleaning water returned from the return port 52 goes to the water spraying outflow path 22 (refer to FIG. 4 ), and the path is different depending on the state of the switching rod 35. That is, there are the following two flow paths.

(1) When the faucet is turned on, the switching lever 8 is set to spray water from the water spraying surface s2, and the sliding lever 10 is not operated. At this time, the switching lever 35 is in a restored state (refer to Figures 3 and 5 (a)). At this time, the weir 35d and the rear weir 35f of the switching lever 35 are in a state of contacting the inner surface of the outer peripheral portion 23a of the lever installation portion 23. Therefore, the space of the outer peripheral portion 23a where the small diameter portion 35b is located is closed by the weir 35d and the rear weir 35f along the two sides of the long direction of the switching lever 35 in the front-to-back direction. On the other hand, in the up-down direction, the opening of the return port 52 is connected to the drain hole 25.

Therefore, the water returned from the return port 52 passes through the drain hole 25, reaches the midway opening 24, and flows to the water spraying outflow path 22. At this time, the water flowing through the water spraying outflow path 22 is a small amount, and the water sprayed from the spray port 45a of the cleaning water spraying part 45 is a thin stream of water.

(2) When the faucet is turned on, the switching rod 8 is set to spray water from the spray surface s2, and the sliding rod 10 is operated. At this time, the coil spring 36 is compressed, and the switching rod 35 is moved to the limit of movement (refer to Figure 5 (b)). At this time, the weir portion 35d and a part of the small diameter portion 35b of the switching rod 35 move to the position of the midway opening 24. Therefore, the opening of the return port 52 and the midway opening 24 are formed in a state of spatial communication along the length of the switching rod 35.

Therefore, the water returned to the return port 52 reaches the midway opening 24 along the length of the switching rod 35 and flows to the water jetting outflow path 22. At this time, since the weir 35d that blocks the water flow does not play the function of blocking the weir, a sufficient amount of cleaning water flows through the water jetting outflow path 22, and the water jetted from the ejection hole 45a of the cleaning jetting part 45 can be formed into a strong water jet for cleaning.

Thus, the flow path inside the shower head 2 that ends at the water spraying surface s2 is divided into a general flow path for strong water spraying and a drainage flow path for weak water spraying. In particular, the flow path that ends at the water spraying outflow path 22 of the flow path portion 21 of the flow path block 20 is divided.

As described above, the cleaning water jet is configured such that the water does not spray out when the switching rod 8 is set to spray water from the water spray surface s2, and sprays out only when the sliding rod 10 is further operated. Therefore, the user can release the high-pressure cleaning water jet with strong water force only by his own intention through the sliding operation.

In addition, since the sliding rod 10 is constructed as a momentary switch, effective cleaning water spraying is performed only during operation, so as long as the pushing operation is stopped, the water spraying will stop immediately. That is, since this shower device 1 sprays powerful water only according to the user's intention and action, it is safe and also helps to save water.

Furthermore, when the faucet is turned on and the switch lever 8 is set to spray water from the water spray surface s2, a thin stream of water is sprayed when the slide lever 10 is not operated. Therefore, even a user who is not familiar with the cleaning water spray function of the shower device 1 can easily understand the specifications of the cleaning water spray function (the position of the water spray opening 4c) and the usage mode. In addition, it can also prevent children from accidentally releasing the strong water force of the cleaning water spray.

Furthermore, the spraying of the thin stream of water also plays a role in preventing the space inside the head housing 3, especially between the weir 35d and the rear weir 35f in the rod installation portion 23, from becoming pressurized due to the water from the return port 52. Therefore, by spraying the thin stream of water, damage to the parts caused by the stress on the parts due to the high pressure inside the head housing 3 can be suppressed. Furthermore, if the inside of the head housing 3 is formed to be high pressure, there is a risk that the water passing plate 70 or the sprinkler plate 75 described later will fall off, but this point can also be suppressed. In addition, when the water pressure (original water pressure) of the trickle water per unit time is about 0.15Mpa, it is ideal to use about 1/10 to 1/3 of the flow rate of the high-pressure cleaning spray water as a high-pressure countermeasure, and preferably about 1/5, but of course it is not limited to this.

Furthermore, the weak water jet when the slide rod 10 is not operated can also be used for weak cleaning in the bathroom by adjusting the size of the drain hole 25. For example, it can also be used to wash away the foam left on the bathroom wall or floor. That is, the shower device 1 can also have two modes of strong water jet and weaker water jet.

In addition, when the sliding rod 10 is not pushed, the method of performing weak water spraying is not limited to using the drainage hole 25 as described above, and other methods (structures) may be adopted. For example, a small gap may be provided between the outer peripheral portion 23a of the rod installation portion 23 and the weir portion 35d of the switching rod 35, and the faucet water flows from this gap to the water spraying outflow path 22. This gap and the drainage hole 25 may also be used together.

Next, the branching control of the faucet water in the branching portion 50 disposed below the flow path block 20 and the water spraying from the shower surface s1 will be further described with reference to FIG6 . FIG6(a) is a bottom view of the flow path block 20, FIG6(b) is a bottom view of the branching portion 50, and FIG6(c) is a schematic cross-sectional view of the main parts showing the relationship between the substrate portion 26 of the flow path portion 21 and the branching portion 50 with respect to the inflow of the faucet water into the branching portion 50.

The branching portion 50 is in the shape of a disk and is provided with a surrounding wall 51 protruding toward the upper side (refer to FIG. 2 and FIG. 3 ), a return port 52 protruding toward the upper side (refer to FIG. 2 and FIG. 3 ), and a plurality of connecting holes 53 (refer to FIG. 2 , FIG. 3 and FIG. 6 (b) ).

On the other hand, as described above, the flow path block 20 is formed such that the branch portion inlet 21c and the insertion port 27 are connected to the back side of the substrate portion 26. In addition, a wall-like blocking portion 28 is formed on the back side of the substrate portion 26 to block water flowing in from the branch portion inlet 21c from flowing out to the side (see FIG. 6(a)).

As shown in FIG3 , the base plate 26 and the branching portion 50 of the flow path block 20 are connected by the insertion of the return port 52 into the insertion port 27 and the engagement of the claws 29 and 57. In addition, the gasket 30 (see FIG2 . In FIG3 , it is shown on the branching portion 50 side) is installed between the claw 29 and the surrounding wall 51 on the back side of the base plate 26.

6 (c), the lower end opening of the shielding portion 28 on the back side of the substrate portion 26 is covered with a covering gasket 31 having an insertion hole 31a, and the covering gasket 31 abuts (presses) the upper surface of the divergent portion 50.

The substrate portion 26 and the branch portion 50 of the flow path block 20 are arranged in a mutually connected and abutting relationship as described above. In addition, in order to cover the gasket 31 and maintain the press-fit relationship between the substrate portion 26 and the branch portion 50, a coil spring (not shown) is arranged in the shielding portion 28.

In this abutting state, the insertion hole 31a formed in the covering gasket 31 is connected to a part of the plurality of communication holes 53 provided in the divergent portion 50, so that the divergent portion inlet 21c of the inflow path 21b is connected to the lower side of the divergent portion 50.

The plurality of connecting holes 53 include shower (full) hole 53a, shower (central) hole 53b, and water jet hole 53c. The switching rod 8 is used to rotate the branching portion 50, so that the insertion hole 31a of the cover gasket 31 overlaps with any one of the connecting holes 53, thereby the connecting hole 53 can function as a water outlet.

In the shower device 1 of this embodiment, only one of the three water spraying modes is performed by setting the switching rod 8. Therefore, the cover gasket 31 of the shielding portion 28 mounted on the base portion 26 and the connecting hole 53 form a press-fit relationship as described above, so that water can flow to only one of the three connecting holes 53.

As shown in FIG6(b), a partition wall is formed below the diverging portion 50. The partition wall has an outer wall 54 and an inner wall 55, and a shower (full) hole 53a is provided at a portion spanning the inside and outside of the outer wall 54, a shower (center) hole 53b is provided at a portion of the space surrounded by the outer wall 54 and the inner wall 55, and a water spray hole 53c is provided at a portion inside the inner wall 55.

The back side of the diverging portion 50 is separated by a partition wall (an outer wall 54 and an inner wall 55) to prevent the outer space of the outer wall 54, the space surrounded by the outer wall 54 and the inner wall 55, and the inner space of the inner wall 55 from being connected to each other and the sides.

The diverging portion 50 is fixed to a diverging portion setting plate 60. The diverging portion setting plate 60 is disc-shaped and has a recess 61 (see FIGS. 2 and 3 ) formed on the upper surface thereof for accommodating the diverging portion 50. A plurality of shower water inlets 62 (see FIG. 2 ) leading downward are formed on the bottom surface of the recess 61 .

The branch portion setting plate 60 is a structure that rotates by the rotation of the water passing plate 70 and the sprinkler plate 75 described later. In addition, the branch portion 50 is connected and fixed by the engagement of the fixed receiving portion 56 provided on the outer periphery of the branch portion 50 and the fixed protrusion 63 provided on the inner periphery of the recess 61, and can rotate with the rotation of the branch portion setting plate 60. The water passing port 62 on the bottom surface of the recess 61 of the branch portion setting plate 60 is not provided in the area surrounded by the inner side of the inner wall 55 provided on the lower side of the branch portion 50 when the branch portion 50 is connected.

Furthermore, a disc-shaped water-passing plate 70 is connected to the lower side of the branch portion setting plate 60, and a sprinkler plate 75 arranged on the lower side is fixed to the water-passing plate 70. The connection between the branch portion setting plate 60 and the water-passing plate 70 is performed by the engagement of the engagement protrusion 64 provided on the outer periphery of the branch portion setting plate 60 and the engagement receiving portion 72 provided on the outer periphery of the water-passing plate 70.

The water-passing plate 70 is formed with a plurality of fitting holes 71 and a rod protrusion 73 is formed on the bottom surface. On the other hand, the water-sprinkling plate 75 is formed with a plurality of water-passing cylinders 76 and a rod outer peripheral portion 78 having a hollow interior is formed on the bottom surface.

The connection between the water-passing plate 70 and the sprinkler plate 75 is performed by inserting the water-passing cylinder 76 into the fitting hole 71 and installing the rod protrusion 73 into the rod outer peripheral portion 78. The water-passing cylinder 76 leads to the sprinkler hole 77 on the lower surface of the sprinkler plate 75. In this way, the shower sprinkler path and the switching rod 8 are formed by connecting the water-passing plate 70 and the sprinkler plate 75.

If the switching lever 8 is set to sprinkle water from the shower surface s1 (standard sprinkle), the faucet water will flow from the shower (center) hole 53a into the space surrounded by the back outer wall 54 and the inner wall 55. The inflowing water passes through the water opening 62 of the branching portion setting plate 60 and flows to the central part of the water passing plate 70, and standard sprinkle is performed.

If the switching lever 8 is set to sprinkle water from the shower surface s1 (full sprinkle), the faucet water will flow from the shower (full) hole 53b to branch into the space outside the outer wall 54 and the space surrounded by the outer wall 54 and the inner wall 55. The water flowing into the space outside the outer wall 54 flows through the water opening 62 to the outer periphery of the water passing plate 70, and the water flowing into the space surrounded by the outer wall 54 and the inner wall 55 flows through the water opening 62 to the center of the water passing plate 70. As a result, full sprinkle is performed.

When the switching lever 8 is set to spray water from the spray surface s2, since there is no water passage 62 of the diverging portion setting plate 60 in the space inside the inner wall 55, the faucet water flows into the return port 52 in the center of the diverging portion 50 set in the space inside the inner wall 55 and flows back to the flow path portion 21. Since the subsequent flow is as described above, the description is omitted.

In this way, the faucet water flowing into the head housing 3 selects any path of standard sprinkling on the shower surface s1, full sprinkling on the shower surface s1, and spraying on the spray surface s2 through the branching portion 50 to perform sprinkling or spraying.

The water spray surface s2 of the shower device 1 of this embodiment adopts the structure of five spray holes 45a with a diameter of about 1 mm arranged side by side as mentioned above, but it is certainly not limited to this structure.

The inventors of this case conducted a comparative test of the spray holes 45a of the above-mentioned embodiment with five holes, six holes, seven holes, and fourteen holes, and the result confirmed that the one with five holes can remove dirt the fastest. The dirt is the dirt caused by toothpaste applied on the bathroom surface.

Specifically, for the shower device 1 of this embodiment (with five ejection holes 45a), at a water pressure of 0.1Mpa, the water flow impact force is 0.2N/mm2, and the time to remove dirt is about 3sec. When there are six ejection holes 45a, at a water pressure of 0.1Mpa, the water flow impact force is 0.19N/mm2, and the time to remove dirt is about 4sec. When there are seven ejection holes 45a, at a water pressure of 0.1Mpa, the water flow impact force is 0.15N/mm2, and the time to remove dirt is about 8sec. When there are fourteen ejection holes 45a, at a water pressure of 0.1Mpa, the water flow impact force is 0.1N/mm2, and the time to remove dirt is about 16sec. In addition, the test of removing dirt by spraying water from the shower surface s1 was also carried out. The results showed that under the water pressure of 0.1Mpa, the water flow impact force was 0.08~0.020N/mm2, and the dirt removal time was about 30 seconds or more.

Furthermore, the means for controlling the divergence of the water flow for sprinkling and spraying water inside the shower head 2, the means for adjusting the strength (on/off) of the spraying water from the spraying surface s2, etc. are not limited to the means shown in the present embodiment. Furthermore, the means for adjusting the strength (on/off) of the spraying water from the spraying surface s2 is not limited to making the flow path different, and may be a method of using the same flow path and making the water level different.
