Abstract
Description
[Technical Field]
[0001] This invention relates to a shower head with a built-in lighting unit that has LEDs or other devices. [Background technology]
[0002] BACKGROUND ART Shower heads for shower devices used in bathrooms and the like are known that incorporate a lighting mechanism such as an LED for illumination, beauty, sterilization, or the like (see, for example, Patent Document 1).
[0003] However, if the volume of the head part where the spray plate is installed in a shower head is small, the amount of water that can be stored will be small, and the water pressure will easily become unstable (unevenness will occur), and water may not be sprayed evenly from the spray plate.
[0004] In particular, if the lighting mechanism is built into the head, the amount of water that can be stored in the head is reduced, making the above phenomenon more pronounced. Also, it is necessary to provide a water channel to the sprinkler plate that avoids the lighting mechanism (for example, by placing the lighting mechanism in the center and providing a water channel on the outside), which also makes it easy for the water to be sprayed unevenly from the sprinkler plate.

[0022] A preferred embodiment of the present invention will now be briefly described with reference to the drawings, illustrating the operation of the present invention.
[0023] When water supplied into the head portion 3 through the water supply hose 4 and the handle portion 5 is guided to the water outlet 1 via the water passage 9, the straight flow that passes through the water passage 9 collides with the straight flow prevention body 11 and does not directly reach the spray plate 2, but is encouraged to remain within the head portion 3, thereby equalizing the water pressure within the head portion 3.
[0024] Therefore, even in a configuration in which lighting unit 7 is provided inside head unit 3, it is possible to spray water as uniformly as possible from spray plate 2 with a simple configuration. [Example]
[0025] Specific embodiments of the present invention will be described with reference to the drawings.
[0026] As shown in Figure 1, this embodiment is a shower head having a head portion 3 with a spray plate 2 with multiple water outlet holes 1, and a handle portion 5 connected to a water supply hose 4 extending from a water source (not shown) such as a bathroom.
[0027] In this embodiment, an illumination section 7 is provided within the head section 3, and water passage holes 9 are provided around this illumination section 7 to guide water supplied into the head section 3 through the water supply hose 4 and the handle section 5 to the water outlet hole 1.
[0028] 2 to 4, the lighting unit 7 is attached to a lighting unit attachment part 8 that is fixed inside the head part 3. In the drawings, reference numeral 20 denotes a fixing screw for fixing the lighting unit attachment part 8 to a mounting part (not shown) inside the head part 3, and reference numeral 21 denotes a flow path forming part that forms a flow path that guides water to the water passage hole 9.
[0029] In addition, a water passage hole 9 is provided in this lighting unit mounting portion 8 at an outer position of the lighting unit 7 (in this embodiment, the 6 o'clock position when viewed from the front) (the part other than the water passage hole 9 is blocked by the lighting unit mounting portion 8).
[0030] The lighting unit 7 includes an LED 6 and is configured to be powered, for example, by a power-generating water wheel and generator (not shown) installed in the flow path, and to light up when water is sprayed (the LED light is emitted to the outside from the water outlet 1). Note that light-emitting means other than the LED 6 may also be used.
[0031] Further, between the outlet 10 of the water passage hole 9 and the water spray plate 2, a straight flow prevention body 11 is provided which faces the outlet 10 and against which the straight flow passing through the water passage hole 9 collides.
[0032] The straight-travel prevention body 11 is a plate-like body with one side facing the outlet 10 and the other side facing the water spray plate 2, and is made of a transparent material.
[0033] Specifically, the straight-travel prevention body 11 is provided on a transparent cover 12 that covers the illumination unit 7 so as to protrude from the outer periphery of the transparent cover 12.
[0034] In this embodiment, the transparent cover 12 is also provided with a protrusion 16 that protrudes from the outer periphery of the transparent cover 12 and has an insertion hole 15 through which a screw body 14 that is screwed into the screw hole 13 of the lighting unit mounting part 8 is inserted, and multiple straight-line prevention bodies 11 and protrusions 16 are provided alternately on the outer periphery of the transparent cover 12.
[0035] The protruding portion 16 is fixed with a screw body 14 so that one of the straight movement prevention bodies 11 faces the outlet 10.
[0036] In this embodiment, there is one water passage hole 9, and three straight-travel prevention bodies 11 and three protrusions 16 are provided at 120° intervals on the outer periphery of the transparent cover 12. Therefore, regardless of the orientation of the transparent cover 12, by fixing the three protrusions 16 with the screw bodies 14, it is possible to position one of the straight-travel prevention bodies 11 so that it faces the outlet 10.
[0037] As shown in Figure 5, the surfaces of the straight-travel prevention bodies 11 facing the outlet 10 are each configured as a dish with a raised peripheral wall. Therefore, the straight-travel flow is forced to flow backward along the peripheral wall, and instead of heading directly toward the sprinkler plate 2, it remains there, equalizing the pressure and allowing water to be sprayed as evenly as possible from each discharge hole 1. In other words, this effectively prevents a situation in which the amount of water sprayed from the vicinity of the 6 o'clock position of the sprinkler plate 2 directly facing the outlet 10 is too high and the amount sprayed elsewhere is too low.
[0038] The shape of the opposing surface is not limited to a dish shape, but may be a wedge shape that protrudes toward the outlet 10 as shown in Fig. 6, or an inclined surface that is inclined relative to the straight flow as shown in Fig. 7. When the opposing surface of each straight flow prevention body 11 is an inclined surface similar to that shown in Fig. 7, a swirling flow is more likely to occur, making it possible to further uniform the pressure inside the head portion 3.
[0039] Furthermore, filter member 17 is provided on the front side of sprinkler plate 2, at a position around lighting unit 7. Filter member 17 is configured to have an annular member (a perforated portion) with a large number of filter holes arranged in a row, and is arranged so as to close the water passage portion around lighting unit 7. An opening is formed in the center of filter member 17, through which lighting unit 7 and transparent cover 12 are inserted.
[0040] Therefore, filter member 17 prevents foreign matter from adhering to sprinkler plate 2. Furthermore, by equalizing the water pressure with straight-line prevention body 11, the water pressure up to filter member 17 is also equalized, which prevents uneven adhesion of foreign matter to filter member 17, reduces the risk of filter clogging, and makes it possible to maintain an appropriate sprinkler condition (high-quality condition) for a long period of time.
[0041] Since this embodiment is configured as described above, when water supplied into the head portion 3 through the water supply hose 4 and the handle portion 5 is guided to the water outlet port 1 through the water passage hole 9, the straight-line flow that passes through the water passage hole 9 collides with the straight-line prevention body 11 and does not reach the spray plate 2 directly, but rather is encouraged to remain within the head portion 3, thereby equalizing the water pressure within the head portion 3.
[0042] Therefore, even if the lighting unit 7 is provided inside the head unit 3, the water pressure inside the head unit can be stabilized, resulting in a shower head with a simple configuration that can spray water as evenly as possible from the spray plate 2. [Explanation of symbols]
