Description

  The present invention relates to a shower apparatus installed in a bathroom or the like, and more particularly to a technique for discharging a cloudy shower mixed with fine bubbles from a shower head.

  Conventionally, a pressurized air-dissolved hot water obtained by pressurizing and dissolving air in hot water is passed through a pressure reducing valve, and fine bubble mixed hot water generated by the pressure reduction is discharged from the outlet of the shower head to the outside. A shower device is known (see, for example, Patent Document 1). The above conventional shower device includes a pressurized pump for generating pressurized air-dissolved hot water and a fine bubble mixed hot water generation device incorporating a dissolution tank and a decompression means, and a shower is provided from the fine bubble mixed hot water generation device through a hose. It is a mechanism that feeds fine bubble mixed hot water into the head.

However, the conventional shower apparatus has the following problems. That is, since pressure loss occurs when passing through a path in a hose or shower head, it is difficult to rapidly reduce the pressure to near atmospheric pressure with a pressure reducing valve upstream of this, and therefore a sufficient amount of fine bubbles There is a problem that it is difficult to become a cloudy shower containing. In the above conventional shower apparatus, since the discharge port of the shower head is as small as 1 mm or less, the pressure loss when passing through this discharge port becomes large and it is difficult to become a cloudy shower, Since the linear flow sprinkled through the discharge port is thin, it is difficult to confirm the cloudiness, and there is also a problem that it is difficult for the user to realize the effect.

  The present invention has been invented in view of the above problems, and can easily generate and discharge a fine bubble-mixed hot water containing a sufficient amount of fine bubbles. It is an object of the present invention to provide a shower device that can be easily felt visually.

  In order to solve the above-mentioned problems, the present invention provides a fine bubble mixed hot water produced by passing a pressurized air-dissolved hot water obtained by pressurizing and dissolving air in hot water through a pressure reducing means from a water outlet of the shower head 13. It is a shower device that discharges to the outside, and the pressure reducing means is provided in the shower head 13.

  By using such a shower device, the pressurized air-dissolved hot water is rapidly depressurized to near atmospheric pressure immediately before being discharged from the shower head 13 into the atmosphere, and the cloudy fine bubble mixed hot water having a large amount of fine bubbles is obtained. Can be generated. This fine bubble mixed hot water is sprayed to the outside as a cloudy shower S containing a sufficient amount of fine bubbles and having a thick white color. By applying the cloudy shower S to the skin or hair, it becomes possible to lift the dirt by the action of the fine bubbles, or to remove the dirt by the impact when the fine bubbles that have penetrated into the pores are flipped. In other words, it is possible to clean the skin without using soap or shampoo, and to make the skin smooth. This is particularly effective for those who have an allergic constitution such as atopy and can be cleaned gently on the skin. In addition, there is an effect that the effect of the cloudy shower bath is visually felt by looking at the shower that is thickly clouded.

  In the shower device, it is preferable that the pressurized air dissolving means for generating pressurized air-dissolved hot water from the supplied hot water and air is connected to the shower head 13 via the flexible hose 12. . By doing so, it is possible to prevent the shower head 13 from increasing in size and weight while only providing the decompression means in the shower head 13.

  Moreover, in the said shower apparatus, it is suitable that the water outlet of the shower head 13 is a 3-10 mm aperture. By doing in this way, the pressure loss at the time of passing through a discharge outlet can be suppressed, the sudden pressure reduction by a pressure reduction means can be ensured, and the thick cloudy shower S can be implement | achieved. Further, since the linear flow sprinkled through the discharge port becomes thick, the cloudiness can be easily visually recognized, and the effect can be more easily realized.

  In the above shower device, it is also preferable that a transparent portion that allows the inside to be visually recognized is provided at least in a region downstream from the pressure reducing means of the shower head 13. By doing in this way, it will come to be visually recognized easily from the exterior that the cloudy fine bubble mixed hot water is produced in the shower head 13, and it becomes easier to realize the effect.

  Each configuration described above can be appropriately combined without departing from the gist of the present invention.

  The invention according to claim 1 can easily generate and discharge a fine bubble-mixed hot water containing a sufficient amount of fine bubbles, and can also visually sense the white-bubbled fine bubble-mixed hot water visually. There is an effect that it becomes easy.

  In addition to the effect of the invention according to claim 1, the invention according to claim 2 can prevent the shower head from becoming larger and heavier only by providing decompression means in the shower head. There is an effect that can be done.

  In addition to the effect of the invention according to claim 1 or 2, the invention according to claim 3 suppresses pressure loss when passing through the discharge port, and secures a sudden pressure reduction in the pressure reducing means, thereby providing thick cloudiness. There is an effect that it is possible to realize a shower and an effect that the cloudiness can be easily visually recognized because the linear flow sprinkled through the discharge port becomes thick, and the effect can be more easily realized.

  In addition to the effect of the invention according to any one of claims 1 to 3, the invention according to claim 4 can easily visually recognize from the outside how white cloudy fine bubble mixed hot water is generated in the shower head. As a result, the effect is more easily realized.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In FIG. 1, the structure of the shower apparatus of an example in embodiment of this invention is shown roughly. The shower apparatus of this example is installed in a bathroom space. A hot water / water mixing device 2 for temperature adjustment is provided on the inner wall surface (that is, the washroom side) of the bathroom wall 1 or a counter (not shown) fixed to the inner wall surface, and the hot water / water mixing device 2 includes a bathroom. A water supply pipe 3 communicating with the water path outside the wall 1 and a hot water supply pipe 4 communicating with a water heater (not shown) installed outside the bathroom wall 1 are connected to each other.

  A hot water supply pipe 5 is connected to the downstream side from the hot water mixing apparatus 2, and an ejector section 6, a pressure pump 7, and a dissolution tank 8, which will be described later, are directed downstream in the middle of the flow path of the hot water supply pipe 5. They are interposed in this order. The ejector portion 6 is connected to an air supply pipe 9, and a check valve 10 is interposed in the air supply pipe 9. The pressurizing pump 7 pressurizes and sends hot water mixed with air by the negative pressure in the ejector section 6 into the dissolution tank 8 on the downstream side. The dissolution tank 8 has a structure in which the inflowing air and hot water are agitated while being pressurized inside. The agitation tank 8 generates pressurized air-dissolved hot water in which the air is sufficiently pressurized and dissolved in the hot water and remains undissolved. The air thus discharged is discharged to the outside through an air vent valve 11 provided in the dissolution tank 8.

  A flexible hose 12 is extended from the downstream end of the dissolution tank 8, and a shower head 13 is connected to the downstream end of the flexible hose 12. The shower head 13 is a hand shower type comprising a long gripping portion 13a connected to the flexible hose 12, and a trunk portion 13b extending in an L shape from the downstream side of the gripping portion 13a. Hot water sent to the shower head 13 is discharged from each water outlet (not shown) of the water spray plate 14 attached to the downstream end of the body portion 13b toward the outside.

  Here, the flow path in the trunk portion 13b of the shower head 13 has a minute diameter portion in the middle of the passage as a decompression means for rapidly decompressing the pressurized air-dissolved hot water fed through the grip portion 13a. A pressure reducing valve 15 is interposed. That is, the pressurized air-dissolved hot and cold water fed into the shower head 13 is rapidly depressurized to near atmospheric pressure when it reaches the pressure reducing valve 15 in the body portion 13b, and immediately before being discharged from the water spray plate 14. It is a mechanism that generates cloudy fine bubbles mixed hot and cold water.

  The housing forming the body portion 13b of the shower head 13 is formed using a transparent material, and the cloudiness of the fine bubble mixed hot water generated through the pressure reducing valve 15 can be easily visually recognized from the outside. The fine bubble mixed hot water is discharged to the outside as a linear flow from a plurality of water outlets, and becomes a cloudy shower S sufficiently containing fine bubbles. It should be noted that the transparent portion for allowing the hot water flowing in the shower head 13 to be visible is only required to be provided at least in a region downstream of the pressure reducing valve 15 in the housing, and only a part of the trunk portion 13b is transparent. Alternatively, the entire shower head 13 may be transparent.

  Furthermore, each discharge port provided in the shower device of the present example has a large diameter of 3 to 10 mm, and the number is suppressed. As a result, the pressure loss is reduced to increase the generation amount of fine bubbles, and a linear flow sprinkled through the discharge port is provided thick so that the cloudiness can be easily visually confirmed.

  Thus, when the user operates the hot / cold water mixing device 2 to supply hot / cold water at a desired temperature to the hot / cold water supply pipe 5, the negative pressure generated in the ejector section 6 sucks the air from the intake port 9 a at the upstream end of the supply pipe 9. The air is supplied to the ejector section 6 through the check valve 10, and is sent to the dissolution tank 8 through the pressurizing pump 7 and stirred while being mixed with hot water. Here, a sufficient amount of air is pressure-dissolved in hot water to generate pressurized air-dissolved hot water, and the pressurized air-dissolved hot water suddenly passes through the pressure reducing valve 15 in the shower head 13 fed through the flexible hose 12. A large amount of fine bubbles are generated by cavitation under reduced pressure. The cloudy fine bubble mixed hot water containing a large amount of fine bubbles generated by the shower head 13 is sprinkled to the outside immediately after generation through a large-diameter discharge port, and becomes a cloudy shower S having a large amount of fine bubbles.

  If this white cloudy shower S is taken, a large amount of fine bubbles wrap around the skin surface of the whole body, so that dirt is attached to the surroundings of the fine bubbles and floats up. The effect that a shock wave lifts the dirt of the body is obtained. Therefore, the body and hair can be washed without using soap or shampoo, and skin-friendly washing is possible. Also, no soap or shampoo is left unwashed, and safe and harmless cleaning is realized for those who have an allergy such as atopy and pay attention to skin care.

  In addition, the user sees how the white cloudy fine bubble mixed hot water having a large amount of fine bubbles is generated in the shower head 13 and how the white cloudy shower S having a thick white color is discharged from the shower head 13. There is also an effect that the effect of the cloudy shower bath can be visually recognized.

  In addition, in the conventional fine bubble bath enjoyed in the bathtub, the dirt that floated from the body due to the action of the fine bubbles remains in the bathtub, and there was a problem that it took time to care for the subsequent bathtub. In the case of the above-described cloudy shower bath, the dirt that has been lifted by the fine bubbles is washed away as it is in the washing place, so that troublesome care after bathing becomes unnecessary.

  The shower device of the present example described above may be installed in a place other than the bathroom, and can be applied to various uses such as a pet washing device, a car washing device, and a clothes washing device. is there. Further, the pressurized air dissolving means for generating the pressurized air-dissolved hot water from the supplied hot water and air is not limited to the configuration using the dissolution tank 8 or the like as in this example, and the air is pressurized into the hot water. Other configurations may be used as long as they can be dissolved.

It is explanatory drawing which shows the basic composition of the shower apparatus of an example in embodiment of this invention.
