Description

shower equipment

The present disclosure relates to a shower device in which a shower head is formed with a shower surface and a water discharge surface that discharges water in a direction different from the direction of water discharge from the shower surface.

Conventionally, shower heads that are capable of sprinkling and discharging multiple types of water have been proposed. The device disclosed in Patent Document 1 is a multifunctional shower device in which a shower head is provided with two types of water discharge holes having different flow paths.

By providing different types of water sprinkling holes on the shower head in this way, the shower can be used for various purposes. For example, if there are two water jetting surfaces with different directions of water spraying, one can be used for body showering and the other can be used for other purposes, such as cleaning the bathroom.

In recent years, many such shower devices with multiple water spouting surfaces have been tried and proposed, and by providing a lever for switching settings (setting operation section), it is possible to switch between two types of water jetting by operating the lever. It can be done easily.

Patent No. 6222610

However, even if it is possible to easily switch between a body shower and water for other purposes, those who are not familiar with such shower devices may find it difficult to predict the location, direction, and force of the water for other purposes. There is a possibility that you may be surprised by the spouting water.

In other words, when installing a shower head with a water spouting surface that is different from the shower surface, it is important to have a configuration in which the user does not panic due to unexpected water spewing from the water spouting surface, that is, the specific specifications and usage of the water spouting surface. There is a need for a structure that can be easily understood by users.

The present disclosure has been proposed in consideration of such circumstances, and an object of the present disclosure is to provide a shower device that allows a user to easily understand the specifications and usage patterns of water spouted from a water spouting surface that has a different water spouting direction from the shower surface. It is in.

In order to achieve the above object, a shower device of the present disclosure is a shower device in which a shower head is formed with a shower surface and a water spouting surface that spews water in a direction different from the water spouting direction from the shower surface, The mode of water spouting from the water spouting surface includes a mode of water spouting for other purposes different from body use by a predetermined water force, and can be set to be switched between water spouting from the shower surface and water spouting from the water spouting surface. a setting operation section; and a water spouting operation section for operating the water faucet to perform the water spouting for other purposes when the setting operation section is configured to spout water from the water spouting surface, and the water faucet is opened. and when the settings for discharging water from the water spouting surface are made by the setting operation section, when the water discharging operation section is not operated, water is discharged with a weaker force than the water force of the water for other purposes. It is characterized by

The shower device according to the present disclosure may further include two or more configurations selected from the following configurations (1) to (3) in a combinable manner.
Configuration (1): The water discharging operation section is a momentary switch.
Configuration (2): The water spouting surface is provided at the tip of the shower head, and water is spouted in a direction perpendicular to the direction of water spouting from the shower surface.
Configuration (3): The flow path inside the shower head up to the water spouting surface is divided into a normal flow path for strong water spouting and a drain flow path for weak water spouting.

Since the shower device of the present disclosure has the above-described configuration, the user can easily understand the specifications and usage of the water discharge surface, which is different from the shower surface.

FIG.

Embodiments of the present disclosure will be described below with reference to the accompanying drawings. First, the basic configuration of the shower device 1 according to this embodiment will be described. Note that in this specification and claims, the water jet from the shower surface s1 is a type of water spouting, but is described as "water sprinkling" to distinguish it from the water spouting from the water spouting surface s2.

In the present shower device 1, a shower head 2 is formed with a shower surface s1 and a water spouting surface s2 that spouts water in a direction different from the water sprinkling direction from the shower surface s1. The mode of water spouting from the water spouting surface s2 includes a mode of discharging water for other purposes different from that for the body using a predetermined water force.

The shower device 1 includes a setting operation section 8 that can be set to switch between sprinkling water from the shower surface s1 and spouting water from the water spouting surface s2. The shower device 1 also includes a water spouting operation section 10 that is operated to perform water spouting for other purposes when the setting operation section 8 is configured to spout water from the water spouting surface s2.

In the shower device 1, when the faucet is open and the settings for discharging water from the spouting surface s2 are made using the setting operation section 8, when the water discharging operation section 10 is not operated, the water force of the water discharging for other purposes is set. Water is spouted with a weaker force.

Here, the predetermined water force is not defined as a numerical value, but if the other application is for cleaning a bathroom as described later, it is desirable that the water force is stronger than that of the shower surface s1. Moreover, if the purpose is other than bathroom cleaning, it is desirable to set the water force accordingly.

Next, the detailed configuration of the present shower device 1 will be explained with reference to FIGS. 1 to 6. The water spout for other purposes is for cleaning the bathroom in this embodiment, but it may also be used for purposes other than cleaning the bathroom.

This cleaning water spouting surface s2 is provided at the tip of the shower head 2, and water is spouted from the water spouting surface s2 in a direction substantially perpendicular to the direction of water spouting from the shower surface s1. In addition, the cleaning water is water for cleaning the walls, floors, drains, and door sashes of the bathroom, and the force of the water is used to remove dirt, so it is less powerful than the water spray from the shower surface s1. Strong is desirable.

As shown in FIG. 1, the shower device 1 includes a shower head 2 having a head portion 2a and a handle portion 2b. A shower hose (not shown) is connected to the open end 2c of the handle portion 2b (hose attachment port 48a of the inflow portion 48, which will be described later).

Note that in this specification, directions such as up and down are defined based on the front view of FIG. 1(a). Further, the tip (open end) side of the shower head 2 is defined as the front side, and the shower hose side is defined as the back side.

As shown in FIGS. 1(a) and 1(c), a shower surface s1 is formed on the lower surface of the head portion 2a of the shower head 2, in which a plurality of water sprinkling holes 77 are formed so as to spray water mainly toward the human body. has been done.

Further, a water spouting surface s2 is formed on the side end surface of the head section 2a opposite to the handle section 2b (the side end surface on the tip side of the head section 2a). A plurality of spout holes 45a (see FIG. 2, etc.) are provided in the water spouting surface s2, and the faucet water flowing through the shower head 2 is directed toward the tip of the shower head 2 (in the direction of water sprinkling from the shower surface s1). (direction approximately perpendicular to the direction). This discharged water is mainly used for cleaning the bathroom (removing limescale and slime). Since the water spouting direction of the water spouting surface s2 is a direction extending along the longitudinal direction from the tip of the shower head 2, the user can easily aim at the cleaning target when grasping the handle portion 2b, which is convenient to use.

Further, as shown in FIGS. 1(a) and 1(c), a setting operation section 8 that can be rotated along the circumferential direction of the head section 2a is provided near the handle section 2b on the lower surface of the head section 2a. be. This setting operation section 8 is a switching lever 8 for setting any of three modes regarding water sprinkling and water spouting.

The setting of the A position where the switching lever 8 is on the longitudinal extension line of the handle part 2b (the state illustrated in FIG. 1(c)) is the setting where water is sprinkled from the center part s11 of the shower surface s1 (normal setting). ). The setting of the switching lever 8 at position B in FIG. 1(c) is such that water is sprinkled from the central portion s11 and the outer peripheral portion s12 of the shower surface s1 (full surface setting). The setting of the switching lever 8 at the C position in FIG. 1(c) is such that water is spouted from the water spouting surface s2. Switching of the switching lever 8 is performed by rotating the switching lever 8 in the direction of the white arrow in FIG. 1(c).

As shown in FIGS. 1(a) and 1(b), a water discharging operation section (slide lever) 10 that can be slid is provided on the upper surface of the head section 2a. This slide lever 10 is an operation lever for turning on/off the cleaning water discharge. When the faucet is open and the switching lever 8 is set to discharge water from the water discharging surface s2, when the slide lever 10 is slid (operated in the direction of the white arrow), the cleaning Water is spouted. In addition, when the faucet is open and the switching lever 8 is set to spout water from the water spouting surface s2, and the slide operation is not performed, water is spouted with a weaker force than the water force of the cleaning water spout. will be done.

In this embodiment, "the slide operation is being performed" means that the slide lever 10 is in the on position (the left limit position in FIG. 1(a)). The fact that the slide operation is not performed means that the slide lever is in the off position (a position other than the left limit position in FIG. 1(a)). The limit position on the right side in FIG. 1(a) is the standby position of the slide lever, and when the slide lever is located at this position or at a position up to the limit position on the left side, it cannot be said that a slide operation is being performed. The cleaning water spout is turned off.

In this way, when the slide lever 10 is not in the on position, water is not spouted from the water spouting surface s2 at all, but only a small amount of water (trickling water) that can be seen by a person is spouted. In other words, the on/off operation of the slide lever 10 can be said to be an operation to increase or decrease water spouting.

In the present embodiment, the slide lever 10 is a momentary switch, and cleaning water is spouted from the water spouting surface s2 only while the tip of the head portion 2a is pressed with a finger to the leftmost limit position. When the slide lever 10 is released, a trickle of water is spouted.

In this way, since the cleaning water spout is performed in two steps: the operation of the setting operation section 8 and the operation of the water spout operation section 10, there is no risk that the user will be surprised by the powerful force of the cleaning water spout. rare.

If water is spouted simply by setting the switching lever 8 to spout water from the water spouting surface s2, users may be surprised by a strong force of water spouting from a location different from the shower surface s1, or by water spouting in an unexpected direction. There is a risk that you may be However, this shower device 1 can avoid such a situation as much as possible. In other words, according to the present shower device 1, the user can easily understand the specifications and usage of the water spouted from the water spouting surface s2, which has a different water spouting direction from the shower surface s1, by looking at the slight amount of water spouted from the water spouting surface s2. Can be done. Note that the water sprinkling from the shower surface s1 is performed immediately if the switching lever 8 is set to spout water from the shower surface s1 and the faucet is open.

Furthermore, the slide lever 10 may be fixed (locked) in the on position without being released. If the faucet is locked in the on position, it is desirable to close the faucet without releasing the lock and then open the faucet to prevent a strong cleaning water from being ejected. In other words, it is desirable to have a mechanism in which the lock is released, for example, when the faucet is closed or when the switching lever 8 is set to spray water from the shower surface s1.

FIG. 2 is an exploded perspective view of this shower head 2. FIG. 3 is a longitudinal cross-sectional view of a main part of the slide lever 10 of the shower head 2 in an off position (standby state). 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 (direction in which the inside is visible ). The components inside the shower head 2 will be explained based on these figures.

This shower head 2 includes a water spouting operation section 10, a head case 3, a channel block 20, a channel cover 15, a cleaning water discharging section 45, an inflow section 48, a branch section 50, and a branch section installation plate. 60, a water passage plate 70, and a water sprinkling plate 75.

The head case 3 is a case body in which a storage main body portion 4 and a handle outer shell portion 5 are integrally formed. The storage main body part 4 is open on the shower surface s1 side, and the handle outer shell part 5 is a cylindrical body (see FIGS. 1(c) and 2).

A concave lever arrangement part 4a for installing the slide lever 10 is formed on the upper surface of the storage main body 4, and a water spouting opening 4c for forming a water spouting surface s2 is formed on the side surface of the tip of the storage main body 4. ing. The lever arrangement portion 4a is formed to be longer than the slide lever 10 so that the slide lever 10 can be slid between the off position and the on position. A rod holder 12 protruding downward from the slide lever 10 is inserted into the lever arrangement part 4a in the longitudinal direction, and a slide opening 4b for the rod holder 12 to slide is provided.

The slide lever 10 has a plate-shaped base, an operating protrusion 11 on the upper surface of the base, and the aforementioned rod-shaped rod holding section 12 on the lower surface. The rod holding portion 12 has a bifurcated lower end so that it can grip a neck portion 35a of a switching rod 35, which will be described later.

On the top side of the head case 3, there are provided a flow path block 20, a flow path cover 15 disposed on the upper surface side of the flow path block 20, and a cleaning water spout 45 attached to the tip side of the flow path block 20. , and an inlet portion 48 attached to the rear end side of the flow path block 20. The inflow portion 48 is provided with a hose attachment port 48a. The passage cover 15 is provided with an insertion opening 15a through which the rod holding portion 12 of the slide lever 10 is inserted.

The flow path block 20 includes a disk-shaped substrate portion 26 and a flow path portion 21 integrally provided thereon. The flow path portion 21 has an inlet path 21b partitioned by a U-shaped wall portion into which faucet water received through the inflow portion 48 flows. Faucet water enters from the inlet 21a through the cylindrical inflow part 48 and the end opening 21d, flows to the branch part entrance 21c, and flows out to the branch part 50 described later.

In addition, the flow path portion 21 is formed with a rod arrangement portion 23 and a water discharge outlet 22 that serves as a flow path for water discharged from the water discharge surface s2. As shown in FIG. 4(a), the rod arrangement portion 23 is arranged between the bifurcated branch paths of the U-shaped entrance path 21b, and includes a space in which the switching rod 35 is installed horizontally. The outer shell portion 23a is formed so as to be. The lower part of the outer shell part 23a is constituted by a base plate part 26. Further, a round hole 23b (see FIG. 3) is formed at the rear end of the outer shell 23a so that the switching rod 35 can slide therein.

This outer shell part 23a opens upward in the middle of the longitudinal direction, and is L-shaped by this midway opening 24 and the adjacent path (separated by the wall of one branch entrance of the entrance path 21b). A water discharge outlet 22 is configured. Further, on the upstream side (inflow portion 48) of the midway opening 24 where the outer shell portion 23a of the rod arrangement portion 23 is interrupted, a drain hole 25 is provided which opens on the top surface of the outer shell portion 23a.

The inner space of the outer shell part 23a of the rod arrangement part 23 communicates with the opening of the return port 52, which is fitted into the fitting port 27 provided in the lower base plate part 26 at approximately the center. The return port 52 serves as a passage for the cleaning water to return to the water spouting outlet 22 when the switching lever 8 is set to spout water from the water spouting surface s2.

As shown in FIGS. 3 and 4(a), a rod-shaped switching rod 35 with a coil spring 36 disposed on the tip side is disposed inside the rod arrangement portion 23. A neck portion 35a is formed at the rear of the switching rod 35, and the rod holding portion 12 of the slide lever 10 arranged on the upper surface side of the storage main body portion 4 grips the neck portion 35a, so that both members are connected. There is. A coil spring 36 is attached to the tip side of the switching rod 35, and the other end of the coil spring 36 on the tip side is fixed to a coil spring fixing part 41 of a fixing plate 40 attached to the tip of the flow path block 20. ing.

Further, the switching rod 35 has a large diameter portion 35c on the downstream side and a small diameter portion 35b on the upstream side thereof. At the upstream end of the large diameter portion 35c, a weir portion 35d is formed which includes a packing 35e and has a larger diameter than the large diameter portion 35c. A rear weir portion 35f with a packing 35g is also 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 moves forward in the rod arrangement portion 23 while the coil spring 36 is compressed by pushing the slide lever 10 forward, and when the slide lever 10 is released, the coil spring 36 is moved forward. By elastically returning, it moves back to its original position.

Furthermore, an outlet 42 for cleaning running water flowing out from the water outlet 22 of the flow path section 21 is formed at a position adjacent to the coil spring fixing part 41 of the fixing plate 40. A cleaning water spouting section 45 is connected to the front part of the fixed plate 40.

As shown in FIGS. 2, 3, and 4(b), the cleaning water spouting section 45 constitutes a cap-like spouting section for spouting cleaning water. The inlet side of the cleaning water spouting section 45 has an opening for housing the fixing plate 40, and the outlet side has a plurality of (five in the illustrated example) spout holes 45a (see FIG. 2) for spouting cleaning water. has been established. Further, inside the cleaning water spouting section 45, a rectifying path 45c partitioned by a rib plate 45b is formed so as to communicate with each of the five jetting holes 45a. It is preferable that the diameter of the ejection holes 45a is 0.7 mm to 1.4 mm, and the interval is about 1 mm to 3 mm.

Furthermore, the flow of the cleaning water in the flow path section 21 will be explained in detail. It should be noted that whether the water flowing into the shower head 2 is to be flowed as water sprinkling from the shower surface s1 (normal water sprinkling or full surface water sprinkling) or as water spouting from the water spouting surface s2 is determined below the flow path block 20. It is controlled by a branching section 50. The branching control of faucet water by the branching section 50 will be described later together with a description of the branching section 50.

As shown in FIGS. 2 to 4, the cleaning water in the flow path section 21 is such that water that has passed through the inflow section 48 and flowed into the inlet 21b of the flow path section 21 passes through the two branch entrances 21c and flows downward. This is generated by flowing into the branch portion 50 and then returning to the upper flow path portion 21 from the return port 52. A detailed explanation will be given below with reference to FIGS. 3 to 5.

The cleaning water that has returned from the return port 52 heads toward the water discharge outlet 22 (see FIG. 4), but its path differs depending on the state of the switching rod 35. In other words, there are two flows as follows.

(1) When the faucet is open, the switching lever 8 is set to discharge water from the water discharging surface s2, and the slide lever 10 is not operated. In this case, the switching rod 35 is in the return state (Fig. 3 and FIG. 5(a)). At this time, the weir part 35d and the rear weir part 35f of the switching rod 35 are in contact with the inner surface of the outer shell part 23a of the rod installation part 23. Therefore, in the front-rear direction, the space of the outer shell 23a where the small diameter portion 35b is located is closed on both sides along the longitudinal direction of the switching rod 35 by the weir portion 35d and the rear weir portion 35f. On the other hand, in the vertical direction, the opening of the return port 52 and the drain hole 25 form a communication state.

Therefore, the water returning from the return port 52 passes through the drain hole 25, reaches the midway opening 24, and flows into the water discharge path 22. In this case, the amount of water flowing through the water spouting outlet 22 is small, and the water spouted from the spout hole 45a of the cleaning water spouting section 45 becomes a trickle of water.

(2) When the faucet is open, the switching lever 8 is set to discharge water from the water discharging surface s2, and the slide lever 10 is operated. In this case, the coil spring 36 is compressed and the switching rod 35 is in a state where it has moved to the movement limit (see FIG. 5(b)). At this time, part of the weir part 35d and small diameter part 35b of the switching rod 35 has moved to the position of the midway opening 24. Therefore, the opening of the return port 52 and the midway opening 24 are in communication along the space in the longitudinal direction of the switching rod 35.

Therefore, the water that has returned from the return port 52 reaches the midway opening 24 along the longitudinal direction of the switching rod 35 and flows into the water discharge path 22. In this case, since the weir part 35d that blocks the flow of water does not function as a cutoff weir, a sufficient amount of cleaning water passes through the water spouting passage 22, and the water spouted from the spout hole 45a of the cleaning water spouting part 45 is powerful. It can be used as a cleaning water spout with a powerful force.

In this way, the flow path inside the shower head 2 up to the water spouting surface s2 is divided into a normal flow path for strong water spouting and a draining flow path for weak water spouting. In particular, the flow path in the flow path portion 21 of the flow path block 20 is divided until it reaches the water discharge outlet 22.

As described above, the cleaning water is not spouted only when the switching lever 8 is set to spout water from the water spouting surface s2, but is configured to be spouted when the slide lever 10 is further operated. Therefore, the user can discharge a strong force of high-pressure cleaning water only by his or her own will by operating the slide.

Furthermore, since the slide lever 10 is configured with a momentary switch so that effective cleaning water is spouted only while it is being operated, water spouting is immediately stopped when the push operation is stopped. In other words, this shower device 1 is safe and contributes to water conservation because powerful water is spouted only based on the user's intention and action.

Further, when the faucet is open and the switching lever 8 is set to spout water from the water spouting surface s2, and the slide lever 10 is not operated, a trickle of water is spouted. Therefore, even a user who is unfamiliar with the cleaning water spouting function of the present shower device 1 can easily understand the specifications (position of the water spouting opening 4c) and usage mode of the cleaning water spouting function. Furthermore, it is possible to prevent children from accidentally releasing powerful cleaning water.

Furthermore, the trickling of water also serves to prevent water from the return port 52 from increasing the pressure in the space between the weir part 35d and the rear weir part 35f inside the head case 3, especially in the rod arrangement part 23. Therefore, by discharging water little by little, it is possible to suppress damage to the parts due to stress on the parts due to the high pressure inside the head case 3. Furthermore, if the pressure inside the head case 3 becomes high, there is a risk that the water passage plate 70 and the water spray plate 75, which will be described later, may come off, but this can also be suppressed. In addition, the flow rate of trickling water per unit time is about 1/10 to 1/3 of the flow rate of high-pressure cleaning water, more preferably about 1/5, when the water pressure (original pressure) is about 0.15 MPa. Although it is desirable to take measures against high pressure, it is of course not limited to this.

In addition, the weak water discharge when the slide lever 10 is not operated can be used for mild cleaning in the bathroom by adjusting the dimensions of the drain hole 25, etc. For example, it can be used to wash away bubbles left on bathroom walls and bathroom floors. In other words, the shower device 1 can have two types of cleaning water spouting: a strong water jet for cleaning and a weaker water jet for light cleaning.

Note that the method of discharging water with a weak force when the slide lever 10 is not pressed is not limited to the method using the drain hole 25 as described above, and other methods (structures) may also be adopted. good. For example, a slight gap may be provided between the outer shell 23a of the rod arrangement portion 23 and the weir portion 35d of the switching rod 35, and faucet water may flow from the gap to the water outlet 22. . This gap and the drain hole 25 may be used together.

Next, the branching control of faucet water by the branching section 50 disposed below the channel block 20 and the sprinkling of water from the shower surface s1 will be further described with reference to FIG. 6. 6(a) is a bottom view of the channel block 20, FIG. 6(b) is a bottom view of the branching portion 50, and FIG. 6(c) is a diagram showing the flow of faucet water into the branching portion 50. FIG. 3 is a schematic vertical cross-sectional view of a main part showing the relationship between the substrate section 26 and the branch section 50. FIG.

The branching part 50 is disk-shaped, and includes an enclosing wall 51 (see FIGS. 2 and 3) projecting toward the top surface, a return port 52 (see FIGS. 2 and 3) projecting toward the top surface, and a plurality of communication holes 53. (See FIGS. 2, 3, and 6(b)).

On the other hand, as described above, the channel block 20 is formed so that the branching part entrance 21c and the fitting opening 27 communicate with the back side of the substrate part 26. Further, a wall-shaped blocking portion 28 (see FIG. 6(a)) is formed on the back side of the substrate portion 26 to block water flowing from the branching portion entrance 21c from flowing out to the side.

As shown in FIG. 3, the base plate portion 26 and the branch portion 50 of the channel block 20 are connected by fitting the return port 52 into the fitting port 27 and by engaging the

claw pieces

29 and 57 with each other. Note that a packing material 30 (see FIG. 2; shown on the branching portion 50 side in FIG. 3) is interposed between the claw piece 29 on the back surface of the substrate portion 26 and the surrounding wall 51.

Further, as shown in FIG. 6(c), a cover gasket 31 having an insertion hole 31a is placed over the lower end opening of the blocking portion 28 on the back surface of the base plate portion 26, and the cover gasket 31 is brought into contact with the upper surface of the branch portion 50. (pressure welding).

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. Note that a coil spring (not shown) is disposed within the blocking portion 28 in order to maintain the press-contact relationship between the base plate portion 26 and the upper surface of the branch portion 50 by the cover packing 31 .

In the abutting state, the insertion hole 31a formed in the cover packing 31 communicates with a part of the plurality of communication holes 53 provided in the branch part 50, so that the branch part entrance 21c of the inlet path 21b is connected to the branch part 50. It communicates with the lower surface side of the section 50.

There are three types of the plurality of communication holes 53: a shower (full surface) hole 53a, a shower (center) hole 53b, and a water discharge hole 53c. By rotating the branch portion 50 using the switching lever 8 and causing either the insertion hole 31a of the cover packing 31 and the communication hole 53 to overlap, the overlapped communication hole 53 will act as a water inlet.

In the shower device 1 of this embodiment, water is spouted (sprayed) in only one of three water spouting (water sprinkling) modes by setting the switching lever 8 . Therefore, the cover packing 31 attached to the blocking part 28 of the base plate part 26 and the communication hole 53 are in a press-contact relationship as described above so that water can flow through only one type of the three types of communication holes 53. It becomes.

As shown in FIG. 6(b), a partition wall is formed on the lower surface of the branch portion 50. The partition wall has an outer wall 54 and an inner wall 55, and a shower (full surface) hole 53a is provided in a portion spanning the inside and outside of the outer wall 54, and a shower (center) hole is provided in a space surrounded by the outer wall 54 and inner wall 55. 53b is provided, and a water discharge hole 53c is provided inside the inner wall 55.

The back side of the branching portion 50 is provided with a partition wall (outer walls 54 and It is partitioned by an inner wall 55).

This branch section 50 is fixed to a branch section installation plate 60. The branch part installation plate 60 is disk-shaped, and a recess 61 (see FIGS. 2 and 3) for accommodating the branch part 50 is formed in the upper surface. A plurality of shower water holes 62 (see FIG. 2) leading downward are formed in the bottom of the recess 61.

The branch installation plate 60 is configured to rotate by the rotation of a water passage plate 70 and a water sprinkling plate 75, which will be described later. The branch part 50 has a fixed receiving part 56 provided on the outer periphery of the branch part 50 and a fixed protrusion 63 provided on the inner periphery of the recess 61 so as to rotate as the branch part installation plate 60 rotates. are connected and fixed by fitting. The water inlet 62 on the bottom surface of the recess 61 of the branch part installation plate 60 is not provided in the area surrounded by the inner side of the inner wall 55 provided on the lower surface of the branch part 50 in the connected state with the branch part 50. do not have.

Further, a disc-shaped water passage plate 70 is connected to the lower side of the branch part installation plate 60, and a water sprinkler plate 75 arranged on the lower side is fixed to the water passage plate 70. The connection between the branch part installation plate 60 and the water passage plate 70 is achieved by fitting the fitting protrusion 64 provided on the outer periphery of the branch part installation plate 60 and the fitting receiving part 72 provided on the outer periphery of the water passage plate 70. being done.

A large number of fitting holes 71 are formed in the water passage plate 70, and a lever protrusion 73 is formed on the lower surface. On the other hand, a large number of water pipes 76 are formed on the water sprinkling plate 75, and a lever outer shell 78 with a hollow interior is formed on the lower surface.

The connection between the water passage plate 70 and the water sprinkling plate 75 is achieved by fitting the water passage tube 76 into the fitting hole 71 and fitting the lever protrusion 73 into the lever outer shell 78. The water pipe 76 communicates with a water sprinkling hole 77 on the lower surface of the water sprinkling plate 75 . In this way, by connecting the water passing plate 70 and the water sprinkling plate 75, a water sprinkling path for the shower and the switching lever 8 are formed.

If the switching lever 8 is set to water sprinkling from the shower surface s1 (normal water sprinkling), faucet water flows from the shower (center) hole 53a into the space surrounded by the outer wall 54 and inner wall 55 on the back side. The inflow water flows into the center of the water passage plate 70 through the water passage port 62 of the branch part installation plate 60, and normal watering is performed.

If the switching lever 8 is set to water sprinkling from the shower surface s1 (full surface water sprinkling), faucet water flows from the shower (full surface) hole 53b into the space outside the outer wall 54 and the space surrounded by the outer wall 54 and inner wall 55. It flows in such a way that it branches into the space where it flows. Water that has flowed into the space outside the outer wall 54 flows to the outer periphery of the water passage plate 70 through the water passage hole 62 , and water that has flowed into the space surrounded by the outer wall 54 and the inner wall 55 flows through the water passage hole 62 to the water passage plate 70 . flows into the center of the As a result, the entire area is watered.

When the switching lever 8 is set to discharge water from the water discharging surface s2, the water outlet 62 of the branch part installation plate 60 is not provided in the space within the inner wall 55, so faucet water is provided in the space within the inner wall 55. It flows into the return port 52 at the center of the branch section 50 and returns to the flow path section 21. Since the subsequent flow is as described above, the explanation will be omitted.

In this way, the faucet water that has flowed into the head case 3 is routed by the branching part 50 to any one of the following routes: normal water sprinkling from the shower surface s1, full water sprinkling from the shower surface s1, and spouting water from the water spouting surface s2. is selected and water is sprinkled or spouted.

The shower device 1 of this embodiment employs, as the water spouting surface s2, a row of five jet holes 45a each having a diameter of about 1 mm, as described above, but the present invention is of course not limited to this. .

The present inventors conducted a comparative test of the embodiment with 5 ejection holes 45a and those with 6, 7, and 14 holes, and found that the one with 5 holes can remove dirt the fastest. I was able to confirm. The stain used was that of toothpaste applied to the bathroom surface.

Specifically, in the case of the shower device 1 of this embodiment (with five jet holes 45a), when the water pressure is 0.1 Mpa, the water flow impact force is 0.2 N/mm2, and the dirt removal time is about 3 seconds. there were.
When there were six ejection holes 45a, the water impact force was 0.19 N/mm2 at a water pressure of 0.1 Mpa, and the dirt removal time was about 4 seconds.
When there were seven ejection holes 45a, the water impact force was 0.15 N/mm2 at a water pressure of 0.1 Mpa, and the dirt removal time was about 8 seconds.
When there were 14 ejection holes 45a, the water pressure was 0.1 Mpa, the water flow impact force was 0.1 N/mm2, and the dirt removal time was about 16 seconds.
In addition, when a dirt removal test was conducted with water spraying from the shower surface s1, the water impact force was 0.08 to 0.020 N/mm2 at a water pressure of 0.1 Mpa, and the dirt removal time was approximately 30 seconds or more. there were.

In addition, the means for controlling water sprinkling and spouting water within the shower head 2, and the means for controlling the strength (on/off) of water spouting from the water spouting surface s2 are limited to those shown in this embodiment. I can't. Further, the means for controlling the strength (on/off) of the water spouted from the water spouting surface s2 is not limited to using different flow channels, but may also be a method of using the same flow channel and varying the water force. .
