Description

  The present invention relates to a shower head for discharging shower water in a bathroom or a washstand.

  As for shower water used in bathrooms and washstands, carbon dioxide gas is bubbled and mixed with air to stimulate the scalp in order to warm the body, and only hot water is used. Various attempts have been made to increase the functionality as compared with those that discharge the liquid. Various shower heads for enhancing such functionality have been proposed in, for example, Patent Document 1 and the like.

  The “shower head” proposed in Patent Document 1 “suppresses the generation of vortex flow of bubble-containing water in the watering chamber and can discharge the bubble-containing water as a relatively clean linear flow. For the purpose of providing a shower head, as shown in FIG. 6, “the water supply unit 6 and the water supplied from the water supply unit 6 are accelerated and radially spaced apart from each other around the injection center point C”. A throttle channel 14a for spraying the water, an air mixing part 16 that is provided downstream of the throttle channel 14a to generate bubble-mixed water, a water spray surface side part 12 in which water spray holes 12c are formed, and a water spray surface side part 12 and the back side part 20 which forms the water sprinkling chamber 18, and the back side part 20 is on the water spray surface side part from the back side part 20 on the traveling direction straight line of the bubble mixed water ejected from the throttle channel 14a. Extending in the direction of 12, One itself and includes a first wall portion 20c that forms a flow path 18a that can flow along the nozzle face side 12 between the nozzle face side 12 "is intended.

  In addition, in the “shower head” proposed in Patent Document 1, as described in paragraph 0005 of “Document 1”, “(Conventional) shower heads direct water to a water spray plate (jet disk)”. Air is sucked in while accelerating and jetting, and the air mixed with this air flows radially after colliding with the water spray plate. "There was a problem that it was not possible to mix water with high efficiency," he said, "Because the mixed water in the air flows radially after colliding with the water spray plate, the air collides and the bubbles are large The problem is "becoming."

Japanese Unexamined Patent Application Publication No. 2014-133443, Abstract, Paragraph 0005

  By the way, for example, in order to mix air into shower water and to stimulate the scalp during hair washing, larger air bubbles should be better. This is because it is the impact of the “shower water” itself that gives physical stimulation. After the shower water flow is interrupted by the mixed air, the next shower water discharges intermittently. It is because it is thought that irritation is given. On the other hand, when using “carbon dioxide” to warm the body, it seems better to make the bubbles of carbon dioxide as small as possible so that the carbon dioxide itself contacts the body surface. Gas must be prepared separately.

Therefore, the present inventor should use the air filled around the shower head so that the physical stimulation by the shower water containing air bubbles is sufficient, and for that reason. As a result of various investigations regarding the desire to make the structure of the system as simple as possible, the following conclusion was obtained.
(B) Physical stimulation (massage effect) caused by “bubbles” in shower water is higher for large bubbles. (B) Pressure from tap water and hot water mixing tap connected to this ( ^{2 to 4} kgf / cm ² ) Make sure that it works well with the Venturi effect generated by the degree.
(C) The bubbles once generated in the water flow are crushed (become fine), as the inventor of the above-mentioned Patent Document 1 has noticed, “swirl flow” occurs.
(D) What is the water flow containing bubbles (for example, “in the invention described in Patent Document 1,“ extends from the back side 20 toward the water spray side 12, and itself and the water spray side 12 ” Even if it collides with the first wall portion 20c ") that forms the flow path 18a that can flow along the water sprinkling surface side portion 12), the bubbles become fine.
(E) To ensure sufficient physical stimulation by shower water containing air bubbles, shower water should be discharged as perpendicularly to the body surface as possible.

  Therefore, the present inventors have made various studies on how to make this type of shower head as simple as possible with sufficient physical stimulation by shower water containing air bubbles. As a result of overlapping, the present invention has been completed.

  That is, the object of the present invention is to make the physical stimulation by the shower water containing air bubbles sufficiently by making the structure that the air bubbles taken in the venturi part are not crushed as much as possible. It is in providing the shower head which can be performed with a simple structure.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“It is a shower head 100 connected to a water supply hose from a water pipe or a hot and cold water mixing tap and discharging shower water 40 mixed with air into the source water from this water supply hose from the water spray plate 30,
The shower body 11 that allows the shower water 40 to pass therethrough is formed, and the passage body 10 that does not have protrusions that obstruct the flow of the shower water 40 in the shower passage 11, and the passage body 10 and the water supply hose are liquidated. A water supply member 20 having a venturi section 21 that is tightly connected and generates a temporary negative pressure in the source water,
The outer shape of the water supply member 20 is an ellipse, and a first air hole 22 for introducing the air is formed in a portion of the venturi portion 21 located at the long axis end of the ellipse,
The shower head 100 ″ is characterized in that the air bubbles 50 flow in a portion farthest from the center of the shower passage 11 so as not to be crushed in the shower passage 11.

  The shower head 100 according to claim 1 is connected to a water supply hose from a water pipe or a hot and cold water mixing tap (not shown), and before the source water from the water supply hose is discharged from the water spray plate 30, The shower water 40 is obtained by mixing air.

The pressure of the source water from the water pipe or hot water mixing tap is generally about ² to 4 Kgf / cm ² , but if this pressure is used, the venturi effect is sufficiently generated. That is, in the venturi section 21 provided in the shower head 100, as shown in FIG. 2B, a water passage having a diameter gradually increasing from the bottom to the top is formed. Negative pressure is sequentially generated in the source water flowing at a pressure of ² to 4 Kgf / cm ² . A first air hole 22 is formed at a location where the negative pressure is generated, and the first air hole 22 communicates with the outside air as shown in FIG. The outside air, that is, the air is supplied into the passage main body 10 of the shower head 100 through the.

The fluid flowing through the pipe flows faster in the central part of the pipe without the pipe (river bank) resistance than the outer part affected by the pipe resistance or the influence thereof, like the flow of the river. Here, in the shower head 100 according to the present invention, as shown in FIG. 2A, the outer shape of the water supply member 20 is an ellipse, and the portion of the venturi portion 21 that is located at the major axis end of the ellipse In addition, since the first air hole 22 for introducing air is formed, the air introduced from the first air hole 22 flows quickly in the central portion of the pipe line as shown in FIG. Enter the source water while avoiding the source water flow.

The fact that the air introduced from the first air hole 22 does not enter the fast flow in the center means that it is replaced by a vortex created around the fast flow, and “cross-stress ”Is zero (0), the air introduced from the first air hole 22 is relatively long, as shown in FIG. 2 (b). There will be no continuous rod-like bubbles 50. That is, the outer shape of the water supply member 20 is an ellipse, and the first air hole 22 for introducing air is formed in the portion of the venturi portion 21 located at the long axis end portion of the ellipse, whereby the first air hole The air introduced from 22 is not crushed finely, but becomes a continuous rod-like bubble 50 that is relatively long or unbroken.

A relatively long or unbroken continuous rod-shaped bubble 50 coming out of the venturi section 21 is provided with the source water in the passage main body 10 that does not have a projection that obstructs the flow of the shower water 40 in the shower passage 11. Since it flows, it will not be crushed finely even in this passage main body 10, and will reach the back side of the water spray plate 30 while maintaining the state as it is.

  On the back side of the water spray plate 30, as shown in FIG. 3 (a), FIG. 4 and FIG. 5, there is almost no obstruction to the flow of the shower water 40. Although it is divided for each watering hole 31 for the first time when it goes to many watering holes 31 formed in the board 30, it does not become so fine.

  The shower water 40 including the bubbles 50 is discharged from the water spray holes 31 of the water spray plate 30. FIG. 5 shows this state. In FIG. 5, the shower water 40 discharged from one water spray hole 31 of the water spray plate 30 is shown. However, the shower water 40 has a bubble 50 that has not been made fine so far as the air portion 42 shown in the figure. The remaining source water is the hot water portion 41. The hot water portions 41 and the air portions 42 are alternately discharged from the water sprinkling holes 31, and a physical stimulus is given particularly when the front end portion of the hot water portion 41 hits the body. I don't feel that much.

  In other words, the hot water portions 41 and the air portions 42 are alternately discharged from the water spray holes 31 of the water spray plate 30, and physical stimulation is given to the body as “tonton” when the tip of the hot water portion 41 hits the body. Therefore, the physical stimulation by the shower water 40 is sufficient.

  Therefore, the shower head 100 according to the first aspect of the present invention is such that the air bubbles 50 taken in by the venturi portion 21 are not crushed as much as possible, and the physical stimulation by the shower water 40 including the bubbles 50 is sufficient, and the shower head 100 is simple. It is also a structure.

Further, in order to solve the above problems, the means adopted the invention according to claim 2 is explained with reference numeral used in the description of the best mode described below, the shower head according to the claim 1 About 100
“The passage body 10 is bent so that the shower passage 11 bends in the range of 20 ° to 40 ° in the portion of the passage body 10 closer to the water spray plate 30 than the portion gripped by the user's hand. ”
It is.

  The shower head 100 according to claim 2 has almost the same configuration as that according to claim 1 described above, but the point different from that of claim 1 is that the user of the passage body 10 is grasped by the hand. In the portion closer to the water spray plate 30 than the portion, as shown in FIG. 4, the passage body 10 is bent so that the shower passage 11 is bent in a range of 20 ° to 40 °. In other words, the passage main body 10 other than the bent portion is maintained in a substantially straight shape so that the shower passage 11 hardly bends. In the shower head 100 according to an embodiment to be described later, this bending angle is 30 °.

  In the shower head 100 according to this second aspect, the bubble main body 10 is bent in the range of 20 ° to 40 ° as described above, and the other portions are made substantially straight, so that the bubbles 50 are formed in the shower passage 11. It will flow without being crushed. Thereby, the hot water portions 41 and the air portions 42 are alternately discharged from the water spray holes 31 of the water spray plate 30, and physical stimulation is given to the body as “ton ton” when the tip of the hot water portion 41 hits the body. Therefore, physical stimulation by the shower water 40 is sufficient.

The function of not crushing the bubbles 50 is that the outer shape of the water supply member 20 according to claim 1 is made into an ellipse , and air is introduced into a portion of the venturi portion 21 located at the end of the major axis of the ellipse. By adding the configuration of forming the first air holes 22, the height is further increased.

  Moreover, in this shower head 100, since the channel | path main body 10 is bend | folded in the range of 20 degrees-40 degrees, if the channel | path main body 10 is hold | maintained by hand in a natural state and the watering board 30 faces a body, shower water will be shown. 40 is discharged in a substantially right angle state with respect to the body surface. This is particularly noticeable when shower water 40 is used on the shoulders and back. This is because, when a general person uses the shower head 100, it is natural that the hand holding the shower head 100 is slightly separated from the body so that the hand is in close contact with the body. In many cases, the water spray plate 30 is located farther from the body, but by folding the passage body 10 in a range of 20 ° to 40 °, the water spray plate 30 is directed toward the body side. As a result, the shower water 40 is discharged at a substantially right angle to the body surface.

  Therefore, the shower head 100 according to claim 2 is also configured so that the air bubbles 50 taken in by the venturi portion 21 are not crushed as much as possible, and the physical stimulation by the shower water 40 including the bubbles 50 is sufficient and simple. It is also a structure.

Furthermore, in order to solve the above problems, the means adopted the invention according to claim 3 is explained with reference numeral used in the description of the best mode described below, and, above claim 1 or claim For the shower head 100 according to No. 2,
"Shower passage 11 located on the back side of watering plate 30, causes continuous shower passage 11 until then, that the relevant portion of the back surface and the passage body 10 of the sprinkler plate 30 were made parallel"
It is.

  The shower head 100 according to claim 3 has almost the same configuration as that according to claim 1 or claim 2 described above, but the point of difference from that of claims 1 and 2 is that of FIG. As shown to (a) and FIG. 4, while making the shower channel | path 11 located in the back side of the water sprinkling plate 30 continue to the shower channel | path 11 until then, the back surface of the water spray plate 30 and the applicable part of the channel | path main body 10 are parallel. It is to have become.

  That is, in the shower head 100 according to the third aspect, the shower passage 11 located on the back side of the water spray plate 30 is continuous with the shower passage 11 so far, and the back surface of the water spray plate 30 and the corresponding portion of the passage main body 10. Are parallel to each other, the bubbles 50 present in the shower water 40 reach the water spray holes 31 of the water spray plate 30 with almost no obstacles crushing the foam 50 in the way. That is, the bubble 50 flows through the shower passage 11 without being crushed, whereby the hot water portions 41 and the air portions 42 are alternately discharged from the water spray holes 31 of the water spray plate 30, and Since the physical stimulus is given to the body as “ton ton” when the tip hits the body, the physical stimulus by the shower water 40 is sufficient.

The function of not crushing the bubbles 50 is that the outer shape of the water supply member 20 according to claim 1 is made into an ellipse , and air is introduced into a portion of the venturi portion 21 located at the end of the major axis of the ellipse. The structure which forms the 1st air hole 22, or the shower channel | path 11 located in the back side of the water spray plate 30 of Claim 2 is made to follow the shower channel | path 11 until then, and the back surface of the said water spray plate 30 and a channel | path main body By adding a configuration in which 10 corresponding portions are parallel to each other, it is further enhanced.

  Therefore, the shower head 100 according to the third aspect also prevents the air bubbles 50 taken in by the venturi portion 21 from being crushed as much as possible, and the physical stimulation by the shower water 40 including the bubbles 50 is sufficient, which is simple. It is also a structure.

A water supply member 20 having a venturi section 21 that is tightly connected and generates a temporary negative pressure in the source water,
The outer shape of the water supply member 20 is an ellipse, and a first air hole 22 for introducing the air is formed in a portion of the venturi portion 21 located at the long axis end of the ellipse,
The air bubbles 50 flow in the portion farthest from the center of the shower passage 11 so that the air bubbles 50 flow in the shower passage 11 without being crushed.
In the invention according to claim 2,
"The passing path body 10, the portion close to the sprinkler plate 30 than the portion that the user grips with hand, the so shower passage 11 is bent in the range of 20 ° to 40 °, that bending the said passage body 10 "
