Description

The present invention relates to a fine bubble water generator that contains fine bubbles in water, and more particularly to a shower hose with a fine bubble water generator that can be easily attached to a household shower facility.

Microbubbles are microbubbles or nanobubbles (diameter about 50 to 500 nm) whose diameter is about 100 μm or less, and small water bubbles smaller than pores are used for dirt on pores and sweat glands, gaps between fiber tissues, etc. It can effectively remove invading stains and has been rapidly used in recent years, especially in the fields of beauty and health.

High-speed shearing method, pressure crushing method, cavitation method, etc. are known to generate water containing a large amount of such fine bubbles, but most of them use the aspirator method, etc. to suck air from the outside. ing. Alternatively, it is forcibly injected. As one of them, a mixed fluid consisting of a liquid accelerated by the accelerating means and a gas (bubbles having a diameter of about several millimeters) introduced into the casing by the gas-liquid mixing means is cavitationized in the casing to cause micro-bubbles. Microbubble generators that generate bubbles are known (see, for example, Patent Document 1).

In addition, as a method of generating microbubbles from the so-called dissolved air melted in water by the cavitation method without sucking air from the outside, the cross-sectional area perpendicular to the central axis from the inlet to the outlet is used. A first nozzle on the inlet side for water flow that gradually decreases, and a disconnection that is continuously arranged via a communication passage provided through communication from the outlet of the first nozzle and orthogonal to the central axis from the inlet to the outlet. A microbubble generator having a second nozzle on the water outlet side that gradually increases the area and a gap or a side chamber opened only in the communication passage is known (see, for example, Patent Document 2).

A shower head is known as an application of a microbubble generator of a method of generating microbubbles from dissolved air in water by a cavitation method to effects on beauty and health (for example, patent documents). See 3).

However, the micro-bubble generator according to Patent Document 1 is not suitable for household shower equipment directly connected to the water supply because the gas-liquid mixing device for accelerating the water stored in the tank becomes large in size.

Further, the micro-bubble generator according to Patent Document 2 may not be able to supply a sufficient amount of water to be used because the water flow rapidly expanded in the communication passage provided with the concubine is depressurized by the second nozzle. .. Therefore, the width size in the axial flow direction of the concubine must be adjusted according to the situation of the water pressure at that time, and it cannot be easily attached to the shower equipment of the home bath.

Patent Document 3 is a household shower head that generates microbubbles, but the microbubble generator is preliminarily incorporated in the shower head, and is configured to attach the microbubble generator to the existing household shower equipment. It was not done.

By the way, when it is possible to attach a fine bubble water generator to an existing shower facility later, there are the following problems. FIG. 1 shows an example of a household shower facility. Connection fittings 13 are attached to both ends of the shower hose 10. A male screw is formed on the outer circumference of the water supply port 11a of the cylinder of the shower head 11, and a female screw is formed on the inner circumference of the connection fitting 13 into which the water supply port 11a is fitted. And the shower head are connected. Further, a male screw is formed on the outer circumference of the water discharge port 12a of the cylinder of the water tap 12 that mixes and supplies water and hot water, and a female screw is formed on the inner circumference of the connection fitting 13 into which the water discharge port 12a is fitted. The shower hose 10 and the water tap 12 are connected by screwing the two.

When the fine bubble water generator 14 is to be attached to such an existing shower facility, the fine bubble water generator 14 is located between the shower hose 10 and the shower head 11, or between the faucet 12 and the shower hose 10. Will be attached to. However, since the connection fittings 13 at both ends of the shower hose 10 have a receiving port structure in which the water supply port 11a and the water discharge port 12a are fitted, the fine bubble water generator 14 is interposed between the shower hose 10 and the shower head 11. The end of the shower hose 10 side of the fine bubble water generator 14 (referred to as "A side" for ease of explanation) has a mounting structure in which a male screw is formed on the outer circumference like the water supply port 11a, and is a shower head. The end portion on the 11 side (referred to as the "B side" for the sake of easy explanation) needs to have a socket structure in which a female screw is formed on the inner circumference like the connection fitting 13.

On the other hand, in order to interpose the fine bubble water generator 14 between the water discharge port 12a and the shower hose 10, the B side is connected to the water discharge port 12a and the A side is attached to the water supply port 11a. The bubble water generator 14 has to be attached in the opposite direction, and the flow direction of tap water in the fine bubble water generator 14 is opposite, and even if the connection can be made, the fine bubble water generator 14 does not function.

Therefore, when the fine bubble water generator 14 is attached to the shower equipment, it is limited to either between the shower hose 10 and the shower head 11 or between the water tap 12 and the shower hose 10. However, although the shower hose 10 of the shower facility shown in FIG. 1 can be attached to and detached from both the water discharge port 12a and the water supply port 11a, there are some that can be attached and detached only on one side. The bubble water generator will not be able to be installed later.

From the above points, it is an object of the present invention to provide a shower hose with a fine bubble water generator that can be attached between a shower hose and a shower head or between a water tap and a shower hose.

In order to solve the above problems, the shower hose with a fine bubble water generator of the present invention has fine bubbles that can be attached to a shower facility in which at least one end of the shower hose is detachable from a shower head or a water faucet via a connection fitting. A shower hose with a water generator, a fine bubble generator, a shower head attachment portion provided at one end of the fine bubble generator and detachably connected to a water supply port of the shower head, and the fine bubble generator. It has a water tap attachment part that is provided at the other end of the water tap and can be detachably connected to the water outlet of the water tap, and a first connection part that can be connected to either the shower head mounting part or the connection fitting at one end. In a shower facility in which the shower head and the shower hose are detachable, the shower head is provided with a mounting tool having a second connecting portion that can be connected to any of the water faucet mounting portion and the connecting fitting at the other end. Is connected to the connection fitting at the first connection portion and connected to the water faucet mounting portion at the second connection portion, and the shower head mounting portion is connected to the water supply port to connect the shower head and the water supply port. In a shower facility that can be attached between the shower hose and the water faucet and the shower hose are detachable, the first connection portion connects to the shower head attachment portion and the second connection portion. By connecting to the connection fitting and connecting the water tap attachment portion to the water outlet, the water tap can be attached between the water tap and the shower hose.

In this case, by arranging the fine bubble generator in a flexible hose portion provided with the shower head mounting portion at one end and the faucet mounting portion at the other end, it is convenient to use the shower. Improves sex.

The fine bubble generator is provided with a first water passage whose diameter gradually decreases along the flow direction of water and a plurality of intake holes provided on the inlet side of the first water passage. It has an intake plate and a second water passage that communicates with the outlet side of the first water passage and gradually increases in diameter along the flow direction of water.

Further, in the intake hole, the central axis from the inlet side to the outlet side is inclined with respect to the central axis of the intake plate, so that the water discharged obliquely from the intake hole is the inner wall of the first water passage. Cavitation-derived fine bubbles are effectively generated from the dissolved air in the water under normal tap water pressure because it goes downstream while increasing the flow velocity by swirling. ..

The first waterway and the second waterway have the largest diameter of the first waterway, and the length of each of the first waterway and the second waterway along the flow direction of tap water is the second waterway. By providing the water so as to be large, tap water is rapidly squeezed in the first water passage and blown out to the second water passage at a high pressure, so that a large pressure difference is generated and cavitation bubbles are effectively generated.

By setting the intake plate thickness dimension of the intake plate to at least 1/4 or more of the diameter dimension, water vigorously flows out to the first water passage, and a swirling flow having a high turnover rate is formed in the first water passage. , It is possible to effectively generate a large number of fine bubbles. At this time, by bending the intake hole from the inlet side to the outlet side, the intake hole is twisted, so that the water becomes a swirling flow having a higher rotation rate and is introduced into the first water passage. To. Further, it is preferable to provide a plurality of the intake holes in a circular shape at equal intervals.

Further, a large number of fine bubbles can be effectively generated by forming an uneven surface for generating turbulent flow on the inner surface of the intake hole.

The shower hose with a fine bubble water generator according to the present invention can be used between the shower head and the shower hose by connecting the fixture to either the shower head mounting portion or the water tap mounting portion. It can be attached to any of the spaces between. Therefore, in the existing shower equipment, if the shower hose is detachable from at least one of the shower head and the water tap, a fine bubble water generator can be attached.

The configuration diagram of a general household shower facility is shown. The external view of the shower hose with a fine bubble water generator which concerns on this invention is shown. An explanatory diagram of a state in which a shower hose with a fine bubble water generator according to the present invention is attached between a shower head and a shower hose is shown. An explanatory diagram for attaching a fixture to a shower head mounting portion in a shower hose with a fine bubble water generator is shown. An explanatory diagram of a state in which a shower hose with a fine bubble water generator according to the present invention is attached between a water tap and a shower hose is shown. The side sectional view of the fine bubble generator is shown. The plan view and the side view of the intake plate are shown. A schematic diagram illustrating the generation of cavitation bubbles in a fine bubble generator is shown. A modified example of the intake hole is shown.

An embodiment of the shower hose 1 with a fine bubble water generator according to the present invention will be described with reference to the drawings. FIG. 2 shows an external perspective view of the shower hose 1 with a fine bubble water generator, and a shower head mounting portion 3 that can be detachably connected to the water supply port 11a of the shower head 11 at both ends of the flexible hose portion 2. , A water tap attachment portion 4 that can be detachably connected to the water discharge port 12a of the water tap 12 is provided, and a fine bubble generator (not shown here) is arranged in the hose portion 2. .. A case where the shower hose 1 with a fine bubble water generator is attached to the shower equipment shown in FIG. 1 will be described.

Each of the shower head mounting portion 3 and the water tap mounting portion 4 is formed with a female screw screwed with a cylindrical water discharge port 12a or a water supply port 11a having a male screw formed on the outer periphery thereof. That is, it has the same structure as the connection fitting 13 of the shower hose 10.

The shower hose 1 with a fine bubble water generator is provided with a mounting tool 6, and the mounting tool 6 has a first connecting portion 6a that can be connected to either the shower head mounting portion 3 or the connecting metal fitting 13 at one end. At the other end, a second connecting portion 6b that can be connected to any of the water tap mounting portion 4 and the connecting fitting 13 is provided. Therefore, the first connection portion 6a is composed of a cylinder having a male screw formed on the outer circumference similar to the water supply port 11a of the shower head 11, and the second connection portion 6b has the same inner circumference as the connection fitting 13 of the shower hose 10. It is composed of a cylinder with a female screw formed on it. In the figure shown, the fixture 6 is screwed to the water tap mounting portion 4 at the first connecting portion 6a.

As shown in FIG. 2, when the fixture 6 is connected to the water supply line attachment portion 4 of the hose portion 2 by the first connection portion 6a, the second connection portion 6b is connected to the connection fitting 13 on the shower head 11 side of the shower hose 10. If the shower head mounting portion 3 is connected to the water supply port 11a, the shower hose 1 with a fine bubble water generator can be mounted between the shower hose 10 and the shower head 11 as shown in FIG. ..

Further, as shown in FIG. 4, when the fixture 6 is connected to the shower head mounting portion 3 of the hose portion 2 by the first connecting portion 6a, the second connecting portion 6b is connected to the connecting metal fitting on the water tap 12 side of the shower hose 10. If the water tap attachment portion 4 is connected to the water discharge port 12a while being connected to 13, the shower hose 1 with a fine bubble water generator can be attached between the water tap 12 and the shower hose 10 as shown in FIG. Can be done.

In this way, by reversing the connection direction of the fixture 6 and replacing it with the faucet mounting portion 4 or the shower head mounting portion 3 of the hose portion 2, the shower hose 1 with a fine bubble water generator is replaced with the shower hose 10 and the shower. Regardless of whether it is attached between the head 11 or between the faucet 12 and the shower hose 10, the direction of tap water flowing through the fine bubble generator 5 arranged in the hose portion 2 does not change. The fine bubble generator 5 can effectively generate fine bubbles.

In a shower facility in which the shower hose 10 can be detached from either the water tap 12 or the shower head 11 in this way, select the side that is easy to attach and place the shower hose 1 with a fine bubble water generator between the shower hose and the shower head. , Or can be arbitrarily attached to either the faucet and the shower hose. This means that if the shower hose 10 can be attached to or detached from either the water tap 12 or the shower head 12, at least one of the shower head 11 and the water tap 12 can be freely attached to the shower hose 10, and fine bubbles can be seen. This means that the shower hose 1 with a water generator can be retrofitted to the shower facility.

Next, the fine bubble generator 5 arranged in the hose portion 2 will be described. FIG. 6 shows the configuration of the fine bubble generator 5 in a side sectional view, and the fine bubble generator 5 is provided with a circular intake plate 17 at the intake side end. The water intake plate 17 is fitted with the outer peripheral side portion screwed into the inner circumference of the fine bubble generator 5. A taper 18 is formed in an annular shape at the peripheral end on the water intake side so that tap water can be easily taken in.

In this example, the intake plate 17 has, for example, a diameter dimension d of 13.5 mm and a thickness dimension t of 5 mm. As shown in FIG. 7A, the water intake plate 17 is formed with four round water intake holes 20 that penetrate in the axial direction at equal intervals on a plane in a circular shape. As shown in the side view of FIG. 7B, the intake hole 20 has a central axis L from the inlet side to the outlet side of tap water at a predetermined angle α with respect to the central axis H of the intake plate 17. For example, it is bored in the intake plate 17 in the form of an oblique cylinder inclined at 15 degrees.

The inclination direction of each intake hole 20 at this time is formed in the counterclockwise direction in the figure as shown by an arrow. As a result, the tap water sent in the horizontal direction is discharged in the inclined direction by passing through each intake hole 20, so that the tap water flow is twisted. Therefore, by screwing the intake plate 17 with the inner circumference of the nozzle portion 7 with a left-hand screw in the same rotation direction as the discharged water flow, the tightening direction of the screw and the rotation direction of the discharged water flow can be matched and loosened. not. In addition, in FIG. 7 (b), only one of the intake holes 20 is shown as a representative.

The headrace of the fine bubble generator 5 is connected to a first water passage 21 whose inner diameter gradually narrows from the intake plate 17 toward the center, a throttle portion 22 connected to the first water passage 21, and a throttle portion 22. A second water passage 23 whose inner diameter gradually increases toward the outlet side is formed.

In this example, the diameter of the inlet side of the first water passage 21 is set to be larger than the diameter of the outlet side of the second water passage 23, and the diameter of the first water passage 21 and the second water passage 23 is axial. The dimensions are set longer than the second channel 23. The diameter and length of the entrance of the first water passage 21 can be various in size depending on the situation in order to control the water pressure and the amount of fine bubbles generated. The throttle portion 22 is provided so as to communicate the ends of the first and second water passages 21 and 23 on the smaller diameter side.

The action of generating fine bubbles in the fine bubble generator 5 having the above configuration will be described. The tap water supplied from the water tap 12 supplied to the hose 2 first passes through each intake hole 20 of the intake plate 17, but the tap water passes through the intake hole 20 in the shape of an oblique cylinder to form the center of the intake plate 17. It deviates from the axial direction and flows out in an oblique direction.

As a result, the tap water after passing through the intake hole 20 abuts diagonally on the inner wall of the first water passage 21, so that the tap water advances to the throttle portion 22 while spirally swirling as schematically shown in FIG. Since the first water passage 21 has a narrowed structure, the speed is increased as it approaches the narrowed portion 22, and the speed is increased from the narrowed portion 22 to the second water passage 23.

The water whose speed has been increased in this way is blown out from the throttle portion 22 at a high pressure and diffused in the second water passage 23. As a result, a sudden drop in pressure occurs, and innumerable fine cavitation bubbles are generated in the second water passage 23 and injected into the tap water due to the boiling phenomenon. Therefore, under normal tap water pressure, fine bubbles derived from cavitation are effectively generated from the dissolved air in the tap water and supplied to the shower head 11.

At this time, the diameter of the inlet side of the first water passage 21 of the nozzle 6 is larger than the diameter of the outlet side of the second water passage 23, and the axial dimension of the first water passage 21 and the second water passage 23 is the first. If it is shorter than the two channel 23, the tap water is suddenly squeezed and blown out at a higher pressure, so that a large pressure difference is generated and cavitation bubbles are effectively generated.

Further, by making the surface of the inner wall of the intake hole 20 an uneven surface 20a as shown in FIG. 9A, water is discharged from the intake hole 20 while increasing the degree of turbulence. In this example, a large number of protrusions are provided to form the uneven surface 20a. When the degree of turbulence is improved in this way, the dissolved air in the tap water can be easily taken out, and cavitation bubbles can be effectively generated in the fine bubble generator 5.

Further, as shown in FIG. 9B, the shape of the water intake hole 20 may be a shape in which a bent portion is provided in a slanted cylinder from the inlet side to the outlet side and twisted. As a result, the flow of tap water passing through the intake hole 20 is twisted, and a swirling flow having a higher rotation rate can be generated in the first water passage 21. As a result, the unevenness of the inner wall of the intake hole 20 can be generated. In combination with the surface 20a, the degree of turbulence is further increased, and the effect of generating cavitation bubbles in the fine bubble generator 5 can be improved.

The present invention is not limited to the above embodiment, and various modifications can be made based on the gist of the present invention. For example, up to about 20 intake holes 20 can be provided depending on the flow rate of the installed tap water pipes and the like. Therefore, when the number of intake holes 20 is large, it is preferable to arrange them uniformly and evenly on the plane of the intake plate 17 rather than arranging them in a circle at equal intervals.

In the above embodiment, the diameter of the inlet side of the first water passage 21 is made larger than the diameter of the outlet side of the second water passage 23, and the distance in the central axis direction is longer in the second water passage 23. However, the same diameter may be formed so as to be symmetrical with respect to the throttle portion 22. In short, the relationship between the pressure of tap water blown out from the first water passage 21 and the pressure that decreases due to diffusion in the second water passage 23 produces an appropriate amount of high-quality cavitation bubbles as fine bubbles. It is set so that it can be generated.

Then, in order to generate fine bubbles more efficiently, a plurality of fine bubbles are generated in relation to connecting the first water passage 21 of the fine bubble generator 5 in the subsequent stage to the second water passage 23 of the fine bubble generator 5 in the previous stage. It is preferable to arrange the vessels 5 in series so that cavitation generation is repeated.

In this way, when a shower of fine bubble water generated by the fine bubble generator 5 and blown out from the shower head 11 is taken, the fine bubbles permeate into the pores and scrape out sebum stains, which activates hair roots and has a skin-beautifying effect. be.

Although the fine bubble generator 5 according to the present invention according to the above embodiment has been described, the central axis of the intake hole 20 of the intake plate 17 from the inlet side to the outlet side is inclined with respect to the central axis of the intake plate 17. By forming the shape of the slanted cylinder, tap water passes through the first water passage 21 while swirling, so that the intake hole 20 is a true cylinder shaped along the central axis of the intake plate 17. Compared with the case, the speed when blown out to the second water passage 23 is high, and fine cavitation bubbles can be generated in tap water.

Further, when a swirling flow is generated in the first water passage 21, a large number of fine bubbles can be generated in tap water so that an effective swirling flow having a high turnover rate is generated. Therefore, in order to generate an effective swirling flow having a high rotation rate, a thick intake plate 17 is used to sufficiently secure the length dimension of the intake hole 20 in the axial direction. In that case, as a guideline for the thickness, as shown in FIG. 7B, the ratio (t / d) when the thickness dimension of the intake plate 17 is t and the diameter dimension is d is 1/4 or more. It is better to set it to. In this example, the diameter dimension d is 13.5 mm, while the thickness dimension t is 5 mm.

In this way, if the dimension t of the intake plate thickness is set to at least 1/4 or more of the diameter dimension d and the distance of the central axis in the depth direction of the intake hole 11 is lengthened, tap water will flow out vigorously and the turnover rate will be increased. A high swirling flow is formed in the first water passage 21, and a large number of fine bubbles can be effectively generated.

According to the fine bubble generator 5 according to the present invention, fine bubbles can be effectively generated by cavitation by utilizing the air contained in tap water supplied to a general household. In the case of direct connection to water, the lower limit of general tap water pressure is 1.5 kgf / cm ² to 3 kgf / cm ² (0.15 to 0.3 MPa), and the nozzle portion 22 is supplied to general households. The air contained in the existing tap water can be converted into tap water containing bubbles finely divided by cavitation only by this tap water pressure. In this case, the tap water pressure is optimally supplied at 2.0 to 4.0 kgf / cm ² (0.2 to 0.39 MPa).

The present invention is not limited to the above embodiment, and various modifications can be made based on the gist of the present invention. For example, up to about 20 intake holes 11 can be provided depending on the flow rate of the installed tap water pipes and the like. Therefore, when the number of intake holes 11 is large, it is preferable to arrange them uniformly and evenly on the plane of the intake plate 7 rather than arranging them in a circle at equal intervals.

Further, also in the water passage portion 8, in the above embodiment, the diameter of the inlet side of the first water passage 21 is made larger than the diameter of the outlet side of the second water passage 23, and the distance in the central axis direction is the second passage. Although the water channel 23 is longer, it may be configured to have the same diameter and be symmetrical with respect to the throttle portion 22. In short, the relationship between the pressure of tap water blown out from the first water passage 21 and the pressure that decreases due to diffusion in the second water passage 23 produces an appropriate amount of high-quality cavitation bubbles as fine bubbles. It is set so that it can be generated.

Then, in order to generate fine bubbles more efficiently, a plurality of fine bubbles are connected to the second water passage 23 of the fine bubble generator 5 in the previous stage by connecting the first water passage 21 of the fine bubble generator 5 in the rear stage. It is preferable to arrange the generators 5 in series in the hose portion 2 so that cavitation generation is repeated.
