Description

  The present invention relates to a shower apparatus.

  Conventionally, as a shower device, fine bubbles generated by a fine bubble generator are contained in the shower water, and by taking this shower water, the adsorption action of the fine bubbles acts on the skin surface to improve the dirt removal effect For example, Japanese Patent Application Laid-Open No. H10-228473 is known. Specifically, the fine bubble generating device of this shower device is a gas mixing unit that obtains gas mixed water by mixing gas into water flowing in the water supply channel from the upstream side to the water supply channel connected to the water pipe and reaching the shower head. In addition, a fine bubble generating section for obtaining fine bubbles by applying a shearing force to the bubbles of the gas mixture water to subdivide the bubbles to form fine bubbles is configured.

However, in the said microbubble generator, there existed a possibility that the bubble diameter of the microbubble contained in the shower water discharged from a shower head may become uneven, or a bubble diameter may become comparatively large. In other words, it is difficult to apply a shearing force evenly to the entire gas mixture water in the fine bubble generating part, and the bubble diameter of the fine bubbles becomes uneven due to uneven shearing force. The water supply path leading to the shower head is composed of a flexible hose, and many fine bubbles generated in the fine bubble generating section are arbitrarily united in the flexible hose before moving to the shower head. It was promoted that the bubble diameters were not uniform, and the bubble diameters of the fine bubbles contained in the shower water were larger than the fine bubbles at the time of occurrence. If the bubble diameters of the fine bubbles contained in the shower water are not uniform, the shower water may become cloudy, making it impossible to ensure a good appearance of the shower water, and if the bubble diameter of the fine bubbles contained in the shower water is large Fine bubbles come out from the water, and a large amount of fine bubbles cannot be applied to the skin, so that it is impossible to efficiently obtain the dirt removal effect. It should be noted that, by applying a shear force to the gas mixture water bubbles to subdivide the bubbles to obtain fine bubbles, the bubble diameter is relatively small if the shear force is applied many times to the gas mixture water bubbles. In addition, although it can be made uniform, as a result, the size of the fine bubble generating unit and the size of the fine bubble generating device is increased.

Can be applied to the skin surface to obtain an efficient dirt removal effect.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The shower apparatus 1 of the present invention connects the tip of a water supply pipe to which water or hot water is supplied to the shower head 2, and supplies water supplied to the shower head 2 through the water supply pipe from the shower discharge hole 35 of the shower head 2. This is an apparatus provided with a fine bubble generating device 3 that allows water to be discharged to the outside as shower water and contains 0.1 to 1000 μm fine bubbles in the shower water. Specifically, the water supply path of the water supplied to the shower head 2 includes hot water mixing with a hot water supply pipe 13 extending from a hot water supply section such as a water heater and a water supply pipe 14 extending from a tap water supply section such as a water pipe. A water supply passage 4 connected to the inlet of the valve 15 and connected to the shower head 2 is connected to the outlet of the hot water mixing valve 15, and a water supply flow rate valve 16 constituted by an electromagnetic valve for controlling the amount of discharged water is arranged in the water supply passage 4. And a fine bubble generator 3 is provided.

  The fine bubble generating device 3 includes a gas mixing unit 5 that obtains gas mixed water by mixing gas into water flowing through the water supply channel 4 from the upstream side, a pump 6 that pumps water into the water supply channel 4, and gas A dissolution tank 7a that constitutes a dissolution unit 7 for obtaining gas dissolved water by dissolving bubbles in the mixed water in water under a high-pressure environment, depositing the gas in the gas dissolved water to generate fine bubbles, and containing fine bubbles The fine bubble generating nozzle 8a constituting the precipitation unit 8 for obtaining water is provided in order, and the water supply flow rate valve 16 of the water supply flow rate valve 16 is connected via the control unit 17 by a switch SW interlocked with the operation of the water discharge operation unit (not shown). The fine bubble generating device 3 is driven by opening / closing control and drive control of the pump 6. The driving of the fine bubble generating device 3 is not limited to this, and the user directly operates the switch SW provided at an appropriate position of the vanity 1 to open the water supply flow rate valve 16 via the control unit 17 and the pump 6. May be driven.

  Here, the gas mixing section 5 may employ a forced mixing mechanism that pumps gas to water by an air pump. However, in this example, since no power is required, the structure can be simplified. Ejector mechanism is adopted that naturally draws gas into the water flowing through 4 by the ejector effect. Specifically, it is configured by connecting a gas supply flow path 9 that opens to a room to a negative pressure generating part that is formed by providing a throttle part in the water supply path 4 so that indoor air can be mixed into water. The gas supply passage 9 is provided with a check valve 9a for preventing a back flow of water. Here, in this example, the volume ratio with respect to the water which flows into the said water supply path 4 of the amount of intake air by the said gas mixing part 5 is 0.1 to 10%. Thereby, since a small amount of mixed gas is required, the configuration of the fine bubble generating device 3 can be simplified without requiring an excessive device for gas intake, and the mixed gas can be efficiently dissolved in water. , The density of the bubbles in the gas mixture water is small, the gap between adjacent bubbles is increased to avoid coalescence of adjacent bubbles as much as possible, and contribute to the miniaturization of the bubbles, and the pump through which the gas mixture water passes 6 is intended to reduce the burden placed on it.

  The dissolution tank 7a is divided into a primary tank 20 (a bubbling tank) and a secondary tank 21 (a water level detection tank) by a partition wall 22 as shown in FIG. The side tank 21 has a structure in which the gas circulation part 23 at the upper part of the partition wall 22 and the water passage part 24 at the lower part of the partition wall 22 communicate with each other. An upstream water supply channel 4 is connected to the upper part of the primary tank 20 and a spray nozzle 25 is arranged. A downstream water supply channel 4 is connected to the bottom of the secondary tank 21 and a tank outlet 26 is arranged. An air vent valve 27 is provided on the side wall of the secondary tank 21. In the primary side tank 20, the gas mixture water pumped by the pump 6 is jetted at high speed by the spray nozzle 25 to be bubbled in the tank, and the gas is dissolved in water under a high pressure environment by the pump 6 pumping. The secondary tank 21 is a tank for obtaining gas-dissolved water. The secondary tank 21 raises bubbles that could not be dissolved up to the tank outlet 26 to the gas recirculation part 23, and removed excess gas by the air vent valve 27. It is a tank for stabilizing the water level in 7a and achieving stable operation of the dissolution tank 7a.

  Further, as shown in FIG. 1B, the fine bubble generating nozzle 8a includes a nozzle inlet 28 from the upstream side of the water supply channel 4, a small diameter path 29 that communicates radially from the nozzle inlet 28, and a vortex section 30 that communicates with the small diameter path 29. A nozzle outlet 31 communicating with the vortex portion 30 is provided in order. Here, in the small-diameter path 29, the pressure of the flowing water is abruptly reduced and the dissolved gas in the gas-dissolved water starts boiling under reduced pressure. Have That is, the precipitation part 8 is substantially constituted by the small diameter path 29. Further, the vortex section 30 has a function of generating a vortex flow of water inside and flowing only uniform fine bubbles having a relatively small bubble diameter to the nozzle outlet 31. Specifically, a vortex as indicated by an arrow A is generated in the vortex section 30. Since the central portion of the vortex has a lower flow velocity than the outer peripheral portion of the vortex, the pressure is reduced, and bubbles having a large diameter are formed in the central portion of the vortex due to collision of fine bubbles generated in the small diameter path 29. Since the shear force acts on the vortex due to the velocity gradient generated in the radial direction of the vortex, when a large bubble at the center of the vortex moves to the outer periphery of the vortex by centrifugal force, it is divided by the vortex shear force. It turns into a small bubble. The outer periphery of the vortex is preferentially discharged to the nozzle outlet 31 by the centrifugal force due to the rotation of the vortex as indicated by the arrow B. As described above, a predetermined diameter from which bubbles having a large diameter are removed is removed from the outer periphery of the vortex. Since the following microbubbles are present, microbubbles having a predetermined diameter or less are continuously discharged from the outer periphery of the vortex together with water. That is, according to this vortex part 30, the bubble whose bubble diameter became large for some reason after microbubble generation | occurrence | production can be excluded, and only a microbubble with a bubble diameter of 0.1-1000 micrometers (preferably bubble diameter 150 micrometers or less) at least. It is possible to stably obtain water containing homogeneous fine bubbles composed of The size of the fine bubbles discharged through the vortex section 30 is determined by the angular velocity of the vortex of the vortex section 30. The larger the angular velocity, the smaller bubbles can be discharged, and this vortex angular velocity flows into the vortex section 30. Since it is variable depending on the flow velocity to be generated, desired fine bubbles having a bubble diameter of 150 μm or less can be generated by changing the flow velocity into the vortex section 30.

  Here, in this example, the fine bubble generating nozzle 8 a is provided in the shower head 2, that is, provided in the water supply path 4 inside the shower head 2. Therefore, the fine bubbles immediately after the precipitation can be contained in the water discharge, that is, the fine bubbles having a small and uniform bubble diameter from the shower head 2 before the large number of generated fine bubbles are united and the bubble diameter is increased. It can be contained in the water discharge. Moreover, it is suitable for the hand shower which uses the shower head 2 by hand as the shower apparatus 1 by comprising the flexible water hose 18 which comprises the water supply path 4 downstream from the melt | dissolution part 7 comprised with the melt | dissolution tank 7a. It has a structure. Specifically, in this example, a portion of the water supply path 4 from the melting portion 7 to the shower head 2 is configured by a flexible hose 18. As described above, the shower head 2 is provided with the fine bubble generating nozzle 8a, and the gas dissolved water flows through the water supply path 4 from the dissolving portion 7 constituted by the flexible hose 18 to the shower head 2. In the portion of the water supply channel 4 constituted by the flexible hose 18, the bubbles are dissolved in the water, and the phenomenon that the bubbles are united does not occur. The flexible hose 18 can be used as a shower head regardless of its length. 2 is not affected. Therefore, the shower apparatus 1 of this example can be suitably applied to the hand shower type shower apparatus 1 in which the shower head 2 is attached to the tip of a relatively long flexible hose 18 provided in a bathroom or the like.

  As described above, in the shower device 1 of the present example, the fine bubble inclusion device 3 having the above-described configuration includes fine bubbles containing only fine bubbles having a bubble diameter of 0.1 to 1000 μm (preferably a bubble diameter of 150 μm or less). Shower water can be constituted by water. In particular, the fine bubbles contained in the shower water are those immediately after being generated at the precipitation portion 8 provided in the shower head 2, and before the large number of generated fine bubbles are combined to increase the bubble diameter. The bubble diameter is as small as possible and is extremely uniform. These fine bubbles with a small bubble diameter and extremely uniform are high in specific surface area and internal pressure, so that they do not come out of the shower water immediately and are dispersed throughout the shower water. In addition, the shower water has a uniform appearance that is uniformly clouded without any bias, and a large amount of fine bubbles can be efficiently applied to the skin surface.

  Here, most of the dirt that adheres to the skin surface of the human body is sebum that comes out of the body. This sebum is so-called hydrophobic dirt. When hydrophobic bubbles (fine bubbles) are applied to this hydrophobic dirt. The dirt adheres to the surface of the bubbles and can be peeled off from the skin surface, that is, the dirt can be effectively removed from the skin surface. Therefore, in the shower apparatus 1 of the present example that can efficiently apply a large amount of fine bubbles to the skin surface, the effect of removing dirt can be effectively applied to the skin surface. In particular, hydrophobic dirt such as cosmetics remaining in addition to sebum is also attached to the skin surface of the face, and effective washing of the face can be performed with the shower water of the shower apparatus 1 of this example. . In addition, shower water containing fine bubbles can reduce the frictional resistance between the shower water and the skin surface due to the fine bubbles, so that the impact of the shower water hitting the skin surface can be weakened and the skin contact can be improved. However, microbubbles burst when they collide with the skin surface, and there is an effect that the attached dirt can be peeled off and removed by the ultrasonic waves generated when the microbubbles collapse, improving the dirt removal effect It contributes to. Needless to say, the shower water containing fine bubbles can also have a dirt removing effect on the surface of the bathroom wash area, etc., when it does not hit the human body.

  FIG. 2 shows another example of the embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted. In this example, the melting portion 7 is constituted by a melting tube 7b instead of the melting tank 7a of FIG. For example, the melting tube 7b can be formed of a bellows tube having a continuous resistor 33 for suddenly changing the pressure and flow velocity on the inner surface. The bellows tube is formed by continuously forming an annular recess 33a having an arc cross section in the axial direction of the melting tube 7b, and a connecting portion between the adjacent annular recesses 33a becomes an annular projection 33b protruding into the melting tube 7b. Yes. That is, the melting tube 7b has the smallest diameter at the annular convex portion 33b and the largest diameter at the bottom portion of the annular concave portion 33a, and the diameter gradually changes during that time. When the gas-mixed water pressurized by the pump 16 flows into the tubular body provided with the resistor 33 continuously on the inner surface, the gas-liquid mixed water is greatly disturbed locally by the continuous resistor 33 one after another. The mixture is stirred and mixed in the pressurized state after passing. In this case, in the melting tube 7b formed of a bellows tube, as shown by an arrow C in FIG. 2B, the melting tube 7b hits the continuous annular projection 33b on the inner surface of the melting tube 7b and turns along the inner surface of the annular recess 33a. It is disturbed, and this disturbance is performed one after another over the entire inner circumference of the dissolving tube 7b. Further, as shown in FIG. 2 (c), since the annular convex portion 33b portion has the smallest diameter in the melting tube 7b, the portion including the annular convex portion 33b portion has a high flow velocity and a small pressure, Since the bottom portion of the annular recess 33a has the largest diameter, the portion including the bottom portion of the annular recess 33a has a slow flow rate and a large pressure, whereby the gas-liquid mixed water passing through the dissolution tube 7b has a flow rate and pressure. The sudden change is repeated continuously. By these actions, when the gas mixture water passes through the dissolution tube 7b, it is continuously stirred and mixed, and the dissolution of the gas in the gas mixture water in water is greatly promoted. Further, when the gas-mixed water swirls and disturbs the annular recess 33a of the dissolution tube 7b, the dissolution of the gas in the water is promoted as described above. In this case, the undissolved gas that has not been dissolved 34 accumulates at the bottom of the annular recess 33a. That is, the bottom of the annular recess 33a is a minute gas reservoir in which the undissolved gas 34 is accumulated. And the water which flows while turning the annular recessed part 33a contacts the gas reservoir formed in the pressurized state, and the undissolved gas 34 is effectively dissolved in the water at the interface. This is the same function as that of the previous dissolution tank 7a, and even though the dissolution tube 7b is formed of a tubular body, it is possible to obtain gas dissolved water that effectively dissolves gas in water. Thus, the miniaturized bubble generator 5 can be miniaturized. Furthermore, in this example, the melting tube 7b is configured by the flexible hose 18, and the configuration of the shower device 1 as a hand shower can be simplified.

  FIG. 3 shows still another example of the embodiment. In this example, a high voltage discharge unit 10 that generates ozone is provided in the middle of the gas supply flow path 9. The high voltage discharge unit 10 is driven and controlled via the control unit 17 by the previous switch SW. That is, since the gas mixed in the water flowing through the water supply channel 4 can be composed of ozone, the fine bubble-containing water containing ozone is obtained by generating fine bubbles of ozone through the fine bubble generating device 3, Shower water made of water containing fine bubbles containing ozone can be discharged from the shower head 2. Here, since ozone has a strong oxidizing power, it has a high bactericidal effect and an organic matter decomposing effect. The fine bubbles generated by the fine bubble generating device 3 can be dispersed without having to immediately come out of the water due to the high specific surface area and internal pressure as described above, such as the skin surface. The contact efficiency of the bubble interface with the object to be cleaned is also high. As a result, the synergistic effect of the two can dramatically increase the dirt removal effect and provide a high bactericidal / antibacterial effect.

  FIG. 4 shows still another example of the embodiment. In this example, a hygroscopic portion 11 in which silica gel or the like for dehumidifying gas is loaded in order from the upstream side in the upstream portion of the high-voltage discharge portion 10 in the gas supply flow path 9, oxygen enrichment for imparting oxygen to the gas This is an example in which a film 12 is provided. According to this, the gas dehumidified by the hygroscopic material can be introduced into the high voltage discharge unit 10, and the generation efficiency of ozone in the high voltage discharge unit 10 can be improved. Further, the oxygen enrichment film 12 can increase the oxygen concentration of the gas (when the gas is air, the oxygen concentration is increased to 25 to 40%), and the ozone generation efficiency in the high voltage discharge unit 10 Can be improved. By increasing the ozone generation efficiency in the high-voltage discharge unit 10 in this way, the ozone concentration of the water containing fine bubbles can be increased to further enhance the organic matter decomposition effect and sterilization effect of ozone, and stains on the object to be cleaned The removal effect and the bactericidal / antibacterial effect can be further enhanced.

  5 and 6 show still another example of the embodiment. In this example, as shown in FIG. 5, the bubble diameter adjusting means 19 for adjusting the bubble diameter of the fine bubbles to be included in the shower water is provided in the discharge portion at the tip of the shower head 2 from which the shower water is discharged. . Specifically, as shown in FIG. 6, a water spray plate 36 having a large number of shower discharge holes 35 a is disposed in the discharge portion of the shower head 2. Similarly, an opening having a large number of shower discharge holes 35 b is provided. An area adjustment cover 37 is attached to the tip of the shower head 2 so as to be rotatable and overlapped with the water spray plate 36. By rotating the opening area adjustment cover 37, the shower discharge hole 35a and the opening area adjustment of the water spray plate 36 are adjusted. The size of the overlapping area of the cover 37 with the shower discharge hole 35b (that is, the opening area of each shower discharge hole 35) can be changed. For example, when the opening area of the shower discharge hole 35 is reduced, the width of the pressure fluctuation can be increased, and the shearing force accompanying the pressure fluctuation can be applied to the fine bubbles in the water to promote the refinement of the fine bubbles. The diameter can be adjusted small.

  Thus, in the shower apparatus 1 of this example, the bubble diameter adjusting means 19 can contain in the shower water fine bubbles immediately after being adjusted to a desired bubble diameter that matches the user's purpose, application, and preference. The water containing fine bubbles containing fine bubbles having a desired bubble diameter and high uniformity can be used as shower water, and the usability of the shower device 1 can be improved. For example, if the bubble diameter adjusting means 19 contains fine bubbles having a bubble diameter of 150 μm or less in the shower water, the fine bubbles are spread to the inside of the sweat pores and the pores of the skin surface having a size of about 80 to 150 μm. This is preferable because it can effectively remove even dirt inside the pores and pores.

  As the bubble diameter adjusting means 19, the one shown in FIG. The bubble diameter adjusting means 19 of this example is provided with an opening hole number adjusting cover 38 for freely closing the shower discharge hole 35 of the water spray plate 36 attached to the tip of the shower head 2 so as to be slidable in the circumferential direction. By sliding the cover 38 in the circumferential direction, many shower discharge holes 35 of the water spray plate 36 are gradually closed in the circumferential direction so that the size of the opening area of the entire shower discharge hole 35 can be changed. For example, if the opening area of the entire shower discharge hole 35 is reduced, the width of the pressure fluctuation can be increased, and the shearing force accompanying the pressure fluctuation can be applied to the fine bubbles in the water to promote the refinement of the fine bubbles. The bubble diameter can be adjusted small.

  Moreover, the thing of FIG. 8 is applicable as the bubble diameter adjustment means 19. FIG. The bubble diameter adjusting means 19 of this example is a bubble diameter adjusting unit 39 composed of a plurality of watering plates 36 that can be appropriately attached to the tip of the shower head 2 in a stacked state. Each water spray plate 36 is provided with a shower discharge hole 35. The shower discharge hole 35 is formed in a venturi shape having a throttle portion 40 as shown in FIG. Pressure can be applied to the water passing through the squeezing portion 40 so that the fine bubbles contained in the water can be made fine by applying the shear force due to the pressure fluctuation. And in the bubble diameter adjustment unit 50 of this example, the more the number of the plurality of watering plates 36 that are stacked, the more the shearing force due to pressure fluctuation can be applied to the fine bubbles in a multi-stage, and the miniaturization can be promoted. The bubble diameter can be adjusted small. That is, the user can obtain fine bubbles with a desired bubble diameter by appropriately selecting the number of the water spray plates 36 to be stacked (the number of water spray plates 36 attached to the tip of the shower head 2). Here, although not illustrated in this example, the structure for attaching the water spray plates 36 to each other and the shower head 2 is such that each member can be attached and detached by screwing. It can also be adopted.

  In the above embodiment, the shower device 1 used in the bathroom has been described as an example. Needless to say, the shower device can be applied to, for example, a hand shower type shower device that constitutes a sink of a sink or a kitchen sink. In addition, a uniform good appearance can be obtained in shower water containing fine bubbles, and a good dirt removing effect can be imparted to the skin surface of the hand, the surface of the sink, the surface of the wash bowl, tableware and the like.
