Description

  The present invention relates to a bubble shower that jets and disperses a gas-water mixed flow.

  In detail, the present invention provides, for example, tap water in the tangential direction of the swirl tube from the outside to the inside of the swirl tube through one or more pressurized water inflow holes formed in the tubular wall of the swirl tube. By making the pressurized water flow in, a swirling water flow is formed inside the swirl tube, and a low pressure part generated hydrodynamically at the center of the swirl water flow and the outside of the swirl tube penetrate through the bottom of the swirl tube. The swirl tube communicates with the air tube projecting inside the swirl tube, and the air outside the swirl tube sucked through the air tube is entrained in the swirl water flow to generate bubbles, thereby generating a gas-water mixed flow. In addition to forming an opening in the upper part of the swirl tube, the upper opening of the swirl tube is narrowed so that the cross-sectional area of the opening becomes smaller toward the upper side of the swirl tube, thereby preventing backflow of water or air from the upper part of the swirl tube to the low pressure part By preventing the pressure rise in the low pressure part Place the air-water dispersion means on the upper side of the upper opening of the swirl tube, relates to distributed foam shower water-air mixture flow through the gap between the top of the lower end and the pivot tube of the steam-water dispersing means.

  More specifically, the present invention relates to a bubble shower that promotes the miniaturization of bubbles in a gas-water mixed flow and can be dispersed as a gas-water dispersed flow.

  Conventionally, an air-water mixed flow dispersion device (liquid atomization dispersion device) configured to disperse an air-water mixed flow is known. As an example of this kind of air-water mixed flow dispersion device (fluid atomization dispersion device), for example, there is one described in Utility Model No. 3162867.

  In the air-water mixed flow dispersion device (fluid atomization dispersion device) described in Japanese Utility Model No. 3162867, one or a plurality of pressurized water flow holes (fluid supply holes, water outlets) are formed in the cylindrical wall of the swivel tube. ) Is formed. Furthermore, pressurized water is caused to flow in the tangential direction of the swirl tube from the outside to the inside of the swirl tube through the pressurized water inflow hole (fluid supply hole, water jet port), thereby forming a swirl water flow inside the swirl tube. The

  More specifically, in the air / water mixed flow dispersion device (fluid atomization dispersion device) described in Utility Model No. 3162867, a low pressure portion hydrodynamically generated at the center of the swirling water flow, and the outside of the swirl tube Are communicated with each other by an air pipe (fluid ejection pipe) that penetrates the bottom of the swivel cylinder and protrudes into the swivel cylinder.

  Next, in the air-water mixed flow dispersion device (fluid atomization dispersion device) described in Utility Model No. 3162867, the external air of the swirl cylinder sucked through the air pipe (fluid jet pipe) It is caught in and is made to bubble. As a result, an air-water mixed flow is generated.

  In detail, in the air / water mixed flow dispersion generating apparatus (fluid atomization dispersing apparatus) described in Utility Model No. 3162867, an opening (fluid outlet) is formed in the upper part of the swivel cylinder. Further, the upper opening (fluid outlet) of the swirl tube is narrowed so that the cross-sectional area of the opening (fluid outlet) becomes smaller toward the upper side of the upper portion of the swirl tube.

  Further, in the gas-water mixed flow dispersion device (liquid atomization dispersion device) described in Utility Model No. 3162867, the backflow of water or air from the upper opening (fluid outlet) of the swirl tube to the low pressure portion is prevented. Thus, the air / water dispersion means (fluid dispersion plate, air / water dispersion plate) for preventing an increase in pressure in the low-pressure portion is disposed above the opening (fluid outlet) at the top of the swivel tube.

  Next, in the air-water mixed flow dispersion device (fluid atomization dispersion device) described in Utility Model No. 3162867, the lower end of the air-water dispersion means (fluid dispersion plate, air-water dispersion plate) and the upper part of the swivel cylinder The air-water mixed flow is ejected and dispersed through the gap between the two.

  Utility model No. 3162867

  By the way, in the air / water mixed flow dispersion apparatus described in Utility Model No. 3162867, the volume in the outer cylinder is large, and therefore the pressure in the swivel cylinder 1 cannot be sufficiently obtained by the amount of water flowing in and the water pressure. Insufficient air intake is introduced.

  Therefore, in the air / water mixing / dispersing device described in Utility Model No. 3162867, the dispersion of the air / water mixed flow is remarkably hindered, the water flow when dispersed outside becomes weak, the effect becomes weak, and the effect is reduced.

  As a result, when the supplied water flow rate is small, a sufficient shower effect as bubble water cannot be obtained.

  Therefore, as a result of diligent research, the present inventor has found that the inflow water channel 11 described in Utility Model No. 3162867 is additionally installed in the cylindrical chamber 7 to increase the number of rotations of the water flow, even when the water flow rate is small. It has been found that the amount of air intake can be increased as the pressure in the low pressure part increases.

Further, the rotational speed of the water flow flowing into the inflow water channels 11 and 12 in the previous period is rotated twice in the circumferential direction in the cylindrical chamber 7, and further rotated in the swivel cylinder 1, thereby generating a total of three rotations of water flow. Even if the amount is small, a sufficient effect can be obtained.

  Further, the utility model No. 3162867 has a drawback that the rotational flow speed cannot be sufficiently obtained because the rotational speed in the cylindrical chamber 7 and the swivel cylinder 1 is twice. It has been found that by rotating this three times, the rotational speed gradually increases, and eventually the flow velocity of the gas-water mixed flow F3 is increased.

  That is, an object of the present invention is to provide a bubble shower that can stably maintain the amount of bubbles in the gas-water mixed flow even when the amount of supply water or the supply water pressure is small and has a wide supply water amount.

  Specifically, in the present invention, by accelerating the water flow before flowing into the swirl tube 1, a sufficient rotational speed can be obtained until it flows into the pressurized water flow hole 2 of the swirl tube 1, and more powerful steam A mixed stream is obtained.

  According to the invention described in Utility Model No. 3162867, since there is only one inflow water channel formed in the outer cylinder 1, a water flow having sufficient pressure in the swivel cylinder 1 when the amount of supplied water or water pressure is small Could not be introduced. For this reason, it becomes difficult to introduce a sufficient pressurized water flow into the swirling cylinder, the pressure of the low pressure part generated hydrodynamically at the center of the swirling water flow cannot be obtained sufficiently, and the amount of air suction is small, There was a defect that the swirling bubble water flow was lowered and the effect of foam shower was lowered. As a means for solving this problem, it is possible to apply a sufficient amount of water pressure flowing into the swivel cylinder by installing one more inflow water channel 11 in the outer cylinder and rotating the rotation of the water flow in the outer cylinder twice. Thus, it is possible to generate a fine air / water mixed flow in which sufficient air is sucked in the air / water mixed flow.

  As a result, according to the bubble shower described in claim 1, for example, as in the air-water mixed flow dispersion device described in Utility Model No. 3162867, an additional water conduit is installed rather than the case where there is only one introduction channel. By using two, the swirling speed of the inflowing water increases, the pressure generated in the low pressure portion increases, the amount of air sucked from the air pipe 3 increases, and a large amount of air-water mixed flow is generated in the cylindrical chamber. .

  In the foam shower according to the second aspect, the axis of the circular fluid dispersion plate as the air / water dispersion means is fixed in alignment with the central axis of the cylindrical chamber.

  Therefore, in the bubble shower according to the first aspect, the rotational speed of the inflowing water is increased by additionally installing one inflowing water channel.

Hereinafter, a first embodiment of the bubble shower of the present invention will be described.
FIG. 1 is a front sectional view of a bubble shower according to the first embodiment, FIG. 2 is a plan view of the bubble shower according to the first embodiment, and FIG. 3 is a sectional view taken along line I-I in FIG.

  In the bubble shower of the first embodiment, as shown in FIGS. 1 and 3, for example, one pressurized water inflow hole 2 is formed in the cylindrical wall of the swivel cylinder 1. In the bubble shower of the second embodiment, a plurality of pressurized water inflow holes 2 can be formed in the cylindrical wall of the swivel cylinder 1 instead.

In the bubble shower of the first embodiment, as shown in FIGS. 1 and 3, the pressurized water F ₁ supplied from the pressurized water inflow hole 2 passes through the pressurized water inflow hole 2 from the outside to the inside of the swivel cylinder 1. The swirl water flow F ₂ is formed inside the swirl tube 1. As a result, hydrodynamic low pressure portion P is generated in the central portion of the turning water flow F _2.

Furthermore, in the bubble shower of the first embodiment, as shown in FIG. 1, the low pressure part P and the outside of the swivel cylinder 1 penetrate the bottom of the swivel cylinder 1 and protrude into the swirl cylinder 1. The air pipe 3 communicates with each other. Therefore, the external air A sucked through the air pipe 3 is entrained in the swirling water flow F ₂ by the low pressure effect of the low pressure portion P and is bubbled. As a result, the steam-water mixture flow F ₃ is made to occur.

Moreover, in the bubble shower of 1st Embodiment, the exit opening 4 is formed in the upper part of the turning cylinder 1, as shown in FIG. Further, the outlet opening 4 at the top of the swivel cylinder 1 is narrowed so that the cross-sectional area of the outlet opening 4 becomes smaller toward the upper side of the upper part of the swirl cylinder 1. Therefore, when the air / water mixed flow F ₂ passes through the outlet opening 4, the flow velocity of the air / water mixed flow F ₃ is increased.

  Furthermore, in the bubble shower of the first embodiment, as shown in FIG. 1, the pressure increase in the low pressure portion P is prevented by preventing the backflow of water or air from the outlet opening 4 at the top of the swivel tube 1 to the low pressure portion P. A fluid dispersion plate 5 is disposed on the upper side of the outlet opening 4 at the top of the swivel cylinder 1.

  Specifically, the circular fluid dispersion plate is fixed to one end on the low pressure portion side of the dispersion shaft 6 that coincides with the central axis of the swivel cylinder, and the other end is fixed to the cylindrical chamber 7.

  The length of the dispersion shaft 6 is set so that the pressure in the low pressure portion is kept lowest and the amount of outside air suction is maximized.

In detail, in the bubble shower of 1st Embodiment, as shown in FIG. 1, the cylindrical chamber 7 which has the ceiling part 9 which provided the air-water mixed flow division | segmentation dispersion | distribution hole 8 in multiple numbers in the circumferential direction and radial direction is provided. It provided the dispersion downstream of the swirl tube 1 and the concentric gas-water mixture flow F _3, allowed the introduction of steam-water mixture flow F ₄ which has ejected dispersed into a cylindrical chamber 7, by successive turning collision with subsequent steam-water mixture flow , Promoting further miniaturization of bubbles in the gas-water mixed flow.

  Next, in the bubble shower of the first embodiment, a plurality of gas-water mixed flow divided dispersion holes 8 are ejected to the outside as a bubble shower flow in a wide range.

Specifically, in the bubble shower of the first embodiment, the water flow that flows in from the pressurized water F ₁ is first introduced into the inflow water channel 11, then introduced into the inflow water channel 12, and finally introduced into the swivel cylinder 1, the rate of increase of the water flow sequentially to the process of being introduced into the revolving tube from the mouth, thereby generating greater the hydrodynamic low pressure portion P to the center of turning water flow F _2.

  The foam shower of the present invention can be applied to body skin cleaning, irritation and the like, for example.
