Description

  The present invention relates to a jet nozzle part, a nozzle, and a bathtub with a jet nozzle part attached to a bathtub.

  Conventionally, jet nozzles for jet baths that generate a jet jet by jetting a mixed jet of water and air into water inside a bathtub are known. The ejection nozzle has a tapered tubular portion formed in a tapered shape, and a bubble mixed jet is ejected from the tip of the tapered tubular portion into the water in the bathtub (for example, Patent Document 1). ).

Japanese Patent No. 3108691

  However, in the conventional ejection nozzle, since the bubble mixed jet is ejected from the tip of the tapered tubular portion having a tapered shape, the jet jet strikes the human body in a narrow range. For this reason, the stimulation by the jet jet is too strong to continue to hit the jet jet for a long time. If the water flow of the jet jet is weakened without changing the configuration of the jet nozzle, it feels tickling when it hits the human body and cannot continue to hit the jet jet for a long time. The above publication discloses a configuration in which the jet main body does not hit one specific part of the human body due to the configuration in which the nozzle body is rotated by the water flow, but the flow path is still tapered. In addition, the number of parts increases and the manufacturing process becomes complicated.

  The present invention has been made in view of the above, and an object of the present invention is to provide a jet nozzle unit, a nozzle, and a bathtub with a jet nozzle unit that have a simple configuration that can apply a jetted liquid to a human body in a wide range. Is to provide.

  In order to achieve the above object, the present invention is directed to an ejection nozzle portion (for example, an ejection nozzle portion 60 to be described later) disposed on a wall of the bathtub in order to eject liquid into the interior of the bathtub (for example, an after-mentioned bathtub 10). A tubular portion (for example, a tubular portion 62 to be described later) having one end opening toward the inside of the bathtub, and a center that closes a central portion of the opening at one end of the tubular portion. A wall (for example, a central wall 63 described later) and a peripheral opening (for example, a peripheral opening 641 described later) formed around the central wall and opening from the inside of the tubular portion toward the inside of the bathtub are formed. There is provided an ejection nozzle portion having a surrounding opening forming portion (for example, a surrounding opening forming portion 64 described later).

  The peripheral opening forming portion includes a peripheral portion (for example, a peripheral portion 630 described later) of the central wall and an edge portion of the tubular portion forming the opening of the tubular portion, and the tubular portion is a cylinder. The peripheral edge of the central wall is formed in a circular shape, the peripheral opening is formed in an annular shape, and the peripheral edge of the central wall is inward of the bathtub rather than the opening at one end of the tubular part. Preferably it is located.

  A tubular portion facing surface (for example, a tubular portion facing surface 634 described later) of the central wall facing the inside of the tubular portion has a conical shape that approaches the inner side of the bathtub as it approaches the peripheral edge from the center of the central wall. It is preferable to be formed. Moreover, it is preferable that the internal diameter of the said tubular part is constant along the axial direction of the said tubular part. Moreover, it is preferable that the internal diameter of the said tubular part is larger than the diameter of the peripheral part of the said center wall.

FIG. 4 is a cross-sectional view showing an ejection nozzle portion 60 according to an embodiment of the present invention. FIG. 5 is a cross-sectional view showing a state in which the axial direction X of the tubular portion 62 of the ejection nozzle portion 60 according to the embodiment of the present invention is changed.

The bathtub 100 with an ejection nozzle part has the bathtub 10 (refer FIG. 1), the pump 20, the two nozzles 50 (refer FIG. 2), and the hose 71, as shown in FIG. 1, FIG. Yes. For convenience of explanation, illustration of the bathtub 10 is omitted in FIG.
The bathtub 10 can store water (hot water) inside. The two nozzles 50 are disposed in two through holes formed in the wall surface of the bathtub 10, and eject water (hot water) that is a liquid into the bathtub 10.

  As shown in FIG. 4 and the like, the nozzle 50 includes a nozzle body 51, a suction port portion 52, and an ejection nozzle portion 60. The ejection nozzle unit 60 ejects water (hot water) toward the inside of the bathtub 10. The nozzle body 51 supports the ejection nozzle portion 60 so as to be rotatable. The suction port portion 52 is disposed so as to surround the periphery of the nozzle body 51 and sucks water in the bathtub 10. A part of the nozzle body 51 and the suction port 52 are disposed inside the bathtub 10, and the other part of the nozzle body 51 is disposed outside the bathtub 10.

  The portions of the two nozzle main bodies 51 arranged outside the bathtub 10 are, respectively, a water injection port 511 for supplying water (hot water) to be ejected from the ejection nozzle portion 60 into the bathtub 10, and a water injection port 511. An air supply port 512 is formed in a portion between the jet nozzle portion 60 and air is mixed with water (hot water) flowing through this portion, and the inside of the bathtub 10 that flows into the nozzle 50 through the suction port portion 52. And a discharge port 513 for discharging water (hot water) from the nozzle 50 toward the pump 20. In the present embodiment, the air supply port 512 is sealed by a sealing cap 515, and air (bubbles) is not mixed with water (hot water). Accordingly, only the liquid inside the bathtub 10 is ejected from the peripheral opening 641 of the ejection nozzle portion 60 described later. For this reason, the water (hot water) ejected from the peripheral opening 641 of the ejection nozzle portion 60 does not include bubbles intentionally mixed with the water (hot water) inside the bathtub 10. The bubbles that existed in the water (hot water) are included.

  The two nozzles 50 are connected by a hose 71 to the pump 20 disposed in the vicinity of the bathtub 10 and covered with a soundproof cover 210. The pump 20 is supported by a pump mount 212 supported by a vibration isolation mount 211. The pump 20 includes a suction port 201 and a discharge port 202. The suction port portions 52 of the two nozzles 50 communicate with each other via a relay hose 72, and the suction port 201 of the pump 20 communicates with the discharge port 513 of the nozzle 50 via the hose 71 and the relay hose 72. The discharge port 202 is connected to the water injection port 511 of the nozzle body 51 via the three-way valve 221 and the hose 71. The three-way valve 221 is supported by a three-way valve mount 222 fixed on the pump mount 212.

When the pump 20 is driven, water (hot water) inside the bathtub 10 sucked from the suction port portion 52 of the nozzle 50 flows to the pump 20 via the hose 71 and the relay hose 72. Then, water (hot water) is discharged from the pump 20 to the hose 71, and the hose 71 is branched into two on the way, and the water (hot water) is supplied to the nozzle body 51 of the nozzle 50 through each branched hose 71. To the water injection port 511, passes through the inside of the nozzle body 51, flows into the ejection nozzle portion 60, and is ejected from the ejection nozzle portion 60 into the bathtub 10.
A shoulder bath hose 73 is connected to the pump 20 via a three-way valve 221, and water (hot water) discharged from the pump 20 flows to the shoulder bath hose 73 via the three-way valve 221. It is ejected to the shoulder of the user of the bathtub 100 with the ejection nozzle part.

Next, the ejection nozzle part 60 will be described with reference to FIGS.
In the following description, a direction from a spherical base 61 (described later) toward the central wall 63 is defined as a front direction, a reverse direction thereof is defined as a rear direction, and these are defined as front and rear directions.

  As shown in FIG. 4, the ejection nozzle portion 60 has a spherical base portion 61, a tubular portion 62, a central wall 63, and a surrounding opening forming portion 64. The spherical base 61 has an outer diameter that is substantially spherical. The spherical base 61 is a spherical support 516 provided in the nozzle body 51, and the outer surface of the spherical base 61 is added to the spherical support 516 having a part of a spherical surface having the same diameter as the spherical base 61. It is supported by abutting on the surface and is rotatably supported with respect to the nozzle body 51. Thereby, the axial direction X of the tubular part 62 can be made variable, that is, the direction of the ejection nozzle part 60 can be changed, and thereby the direction of water (hot water) ejected from the ejection nozzle part 60 can be changed. Can be changed.

  The rear end portion of the spherical base 61 is formed in a shape in which a part of the spherical surface is cut out in a virtual plane, and the portion in the cutout shape is orthogonal to the virtual plane. In addition, a through channel 611 that penetrates the spherical base 61 is formed. Water (hot water) from the pump 20 connected to the water injection port 511 of the nozzle body 51 via the hose 71 flows through the through flow path 611. The inner diameter of the through channel 611 is constant along the axial direction of the through channel 611 in the portion of the through channel 611 from the front end of the spherical base 61 to the center of the spherical base 61. In the portion of the through flow path 611 from the center to the rear end of the spherical base 61, the diameter gradually increases along the rear direction. By making the through flow passage 611 into such a shape, the thickness of the spherical base 61 is maintained at a predetermined value, and the strength of the spherical base 61 is maintained.

  The tubular portion 62 is formed in a cylindrical shape, and the rear end portion of the tubular portion 62 is connected to the front end portion of the spherical base portion 61 by being integrally formed. A front end portion of the tubular portion 62 opens toward the inside of the bathtub 10 (toward the front). The tubular portion 62 has a coaxial positional relationship with the through flow path 611 that penetrates the spherical base portion 61. The internal space 621 of the tubular portion 62 communicates with the through flow path 611 of the spherical base 61 and constitutes a flow path of water (hot water) that is a liquid. Except for the front end portion of the tubular portion 62, the inner diameter and the outer diameter of the tubular portion 62 are constant along the axial direction of the tubular portion 62. Further, the inner diameter of the tubular portion 62 is the same as the inner diameter of the portion of the through flow path 611 from the front end of the spherical base portion 61 to the center of the spherical base portion 61 (the portion that is not expanded in the through flow passage 611). The inner diameter of the front end portion of the tubular portion 62 is slightly increased toward the front end edge of the tubular portion 62.

  The central wall 63 has a positional relationship that closes the central portion of the opening at the front end of the tubular portion 62, has a coaxial positional relationship with the tubular portion 62, and is a hollow substantially cone formed in a shape that tapers backward. It is formed into a shape. Accordingly, the peripheral edge 630 of the central wall 63 is formed in a circular shape, and is recessed outward (rearward) of the bathtub 10 in the bathtub internal facing surface 631 which is the front surface of the central wall 63 facing the inside of the bathtub 10. A conical recess 632 is formed. Further, the tubular portion facing surface 634 which is the rear surface of the central wall 63 facing the inside of the tubular portion 62 approaches the inner side (front) of the bathtub 10 as it approaches the peripheral portion 630 of the central wall 63 from the center of the central wall 63. It is formed in a tapered shape. The inner diameter of the tubular portion 62 is larger than the diameter of the peripheral edge portion 630 of the central wall 63. Further, as shown in FIG. 4, the peripheral edge 630 of the central wall 63 is located inward (front) of the bathtub 10 with respect to the front end of the tubular portion 62.

  As shown in FIG. 3, the central wall 63 is integrally formed and connected to the front end portion of the tubular portion 62 by four ribs 636. The ribs 636 are provided at 90 ° intervals in the circumferential direction of the peripheral edge 630 of the central wall 63. The space formed around the central wall 63 and surrounded by the ribs 636, the peripheral edge portion 630 of the central wall 63, and the front end portion of the tubular portion 62 is thinly painted as shown in FIG. The peripheral opening 641 that opens from the inside of the tubular portion 62 toward the inside of the bathtub 10 is configured. As described above, the peripheral edge 630 of the central wall 63 is formed in a circular shape, and since the tubular portion 62 is formed in a cylindrical shape, the opening at the front end portion of the tubular portion 62 is also formed in a circular shape. The peripheral opening 641 is also formed in an annular shape. Here, the annular shape does not mean a complete annular shape, but means a substantially annular shape divided into four in the circumferential direction of the peripheral edge portion 630 of the central wall 63 by the rib 636.

  The flow (spread) of water (hot water) ejected from the ejection nozzle portion 60 in the bathtub 100 with the ejection nozzle portion having the above configuration will be described. FIG. 6 is a schematic diagram illustrating the direction of liquid ejected from the ejection nozzle unit 60 according to an embodiment of the present invention. FIG. 7 is a schematic diagram showing the direction of liquid ejected from the conventional ejection nozzle section 60.

  The water (hot water) that has flowed into the ejection nozzle portion 60 flows along the inner peripheral surface of the tubular portion 62 having a constant inner diameter along the axial center of the tubular portion 62, as indicated by an arrow A in FIG. Flows in the inner space of the tubular portion 62 in parallel to the axial center of the tube. And it collides with the tubular part opposing surface 634 of the central wall 63, and flows inward (front) of the bathtub 10 along the tubular part opposing surface 634 as shown by an arrow B in FIG. It flows out of the part 62 and into the bathtub 10. At this time, since the peripheral opening 641 is configured to open in a direction that forms a predetermined angle with respect to the axial center of the tubular portion 62, water (hot water) is directed toward the opening, respectively. Erupted. For this reason, as shown in FIG. 6, water (hot water) is expelled toward the inside of the bathtub 10 with a spread.

  Therefore, for example, as shown in FIG. 6, when water (hot water) is ejected from the ejection nozzle portion 60 toward the lower portion (waist) of the back H of the user bathing in the bathtub 100 with the ejection nozzle portion. When the sprayed water (hot water) hits the waist, the surface of the waist is slightly reddish. In the case of this embodiment, the redness spreads over the entire waist of the user.

  On the other hand, in the structure which does not have the center wall 63 as in the prior art, as shown in FIG. 7, water (hot water) is ejected vigorously in a direction close to a straight line. For example, when water (hot water) is jetted from the jet nozzle portion 60 toward the waist of a user bathing in a conventional bathtub 100 with a jet nozzle portion, the water (hot water) is vigorous in a narrow range at the waist. Because it often hits the human body, it is locally rounded and reddish in areas where it is exposed to water (hot water), and it feels intensely stimulated.

According to the ejection nozzle part 60 and the bathtub 100 with an ejection nozzle part by embodiment of the said structure, the following effects can be acquired.
In order to eject liquid to the inside of the bathtub 10, the ejection nozzle part 60 of the nozzle 50 disposed on the wall part of the bathtub 10 forms a liquid flow path, and one end opens toward the inside of the bathtub 10. A central wall 63 that closes the central portion of the opening at one end of the tubular portion 62, and a peripheral opening 641 that is formed around the central wall 63 and opens from the inside of the tubular portion 62 toward the inside of the bathtub 10. And a peripheral opening forming portion 64.

  With this configuration, the central portion of the opening of one end (front end) of the tubular portion 62 is blocked by the central wall 63, and water (hot water) is prevented from being ejected vigorously toward the axial direction X of the tubular portion 62. be able to. Further, since water (hot water) can be ejected from the peripheral opening 641, the water (hot water) ejected from the ejection nozzle portion 60 can be diffused in the bathtub 10. As a result, the water (hot water) ejected from the ejection nozzle portion 60 can be applied to the human body in a wide range, and further, the user can enjoy a feeling of being wrapped in the water flow when hitting the human body. Thereby, since the water (hot water) ejected from the ejection nozzle part 60 can be gently applied to a human body, bathing for a long time is possible. Further, since the central wall 63 may be disposed so as to block the central portion of the opening at one end (front end) of the tubular portion 62, the water (hot water) ejected from the ejection nozzle portion 60 can be made with a relatively simple configuration. Can be applied gently to the human body.

  The peripheral opening forming portion 64 has a peripheral edge portion 630 of the central wall 63 and an edge portion of the tubular portion 62 forming the opening of the tubular portion 62, and the tubular portion 62 is formed in a cylindrical shape, The peripheral edge portion 630 of the wall 63 is formed in a circular shape, the peripheral opening 641 is formed in an annular shape, and the peripheral edge portion 630 of the central wall 63 is positioned inward (front) of the bathtub 10 with respect to the opening at one end of the tubular portion 62. doing.

  With this configuration, the direction of water (hot water) ejected from the ejection nozzle portion 60 can be a direction that forms a predetermined angle with respect to the axial direction X of the tubular portion 62 and is ejected from the peripheral opening 641. Water (hot water) can be more diffused in the bathtub 10.

  Further, the tubular portion facing surface 634 of the central wall 63 facing the inside of the tubular portion 62 is formed in a conical shape that approaches the inside of the bathtub 10 as it approaches the peripheral portion 630 from the center of the central wall 63. With this configuration, the flow of water (hot water) flowing through the inside of the tubular portion 62 can be changed along the tubular portion facing surface 634 so as to be separated from the axial center of the tubular portion 62.

  Further, the inner diameter of the tubular portion 62 is constant along the axial direction of the tubular portion 62. With this configuration, the flow of water (hot water) inside the tubular portion 62 can be corrected to a linear flow along the axial center of the tubular portion 62. In this manner, water (hot water) corrected to a linear flow can be ejected into the bathtub 10 along the tubular portion facing surface 634 of the central wall 63.

  Further, the inner diameter of the tubular portion 62 is larger than the diameter of the peripheral edge portion 630 of the central wall 63. With this configuration, water (hot water) can be ejected from the ejection nozzle portion 60 by two flows, a linear flow along the axial center of the tubular portion 62 and a flow along the central wall 63. Water (hot water) can be ejected so as not to spread too far away from the axis of the tubular portion 62.

  Further, the central wall 63 is fixed to the tubular portion 62. A recessed portion 632 that is recessed outward from the bathtub 10 is formed on the bathtub interior facing surface 631 of the central wall 63 that faces the interior of the bathtub 10. And the nozzle 50 is provided with the nozzle main body 51 which supports such an ejection nozzle part 60 in the axial center direction of the tubular part 62 variably. With this configuration, when the direction in which the water (hot water) ejected from the ejection nozzle portion 60 is to be ejected is changed, for example, the user of the bathtub 100 with the ejection nozzle portion puts his finger into the recess portion 632 and the center wall By changing the direction of 63, the spherical base 61 is rotated with respect to the spherical support portion 516 provided in the nozzle body 51, and the direction of the ejection nozzle portion 60, that is, the axial direction X of the tubular portion 62 is easily achieved. Can be changed.

In the bathtub 100 with an ejection nozzle part, the surrounding opening 641 of the ejection nozzle part 60 circulates and ejects only the liquid inside the bathtub 10 as it is.
With this configuration, the entire flow rate of water (hot water) ejected from the ejection nozzle portion 60 can be reduced, and the water (hot water) ejected from the ejection nozzle portion 60 can be softly applied to the human body. Furthermore, since air having a temperature lower than that of water (hot water) is not mixed, a decrease in the temperature of water (hot water) can be suppressed, and the heat retaining effect of water (hot water) can be improved. Moreover, the flowing sound at the time of ejecting water (hot water) from the ejection nozzle part 60 can be made small, and the relaxation effect in the user of the bathtub 100 with an ejection nozzle part can be heightened. Moreover, since downstairs noise can be reduced, the bathtub 100 with a jet nozzle part can be installed also in apartment houses, such as an apartment, and the choice of an installation environment can be expanded.

The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, the structure of each part of the ejection nozzle part, the nozzle, and the bathtub with the ejection nozzle part is not limited to the structure of each part of the ejection nozzle part 60, the nozzle 50, and the bathtub 100 with the ejection nozzle part in the embodiment. For example, the configuration of the tubular portion, the central wall, the peripheral opening, and the like is not limited to the configuration of the tubular portion 62, the central wall 63, the peripheral opening 641, and the like in the present embodiment. Moreover, although the hollow part 632 and the tubular part opposing surface 634 were formed in the cone shape, it is not limited to a cone shape, For example, a triangular pyramid shape etc. may be sufficient. In addition, the central wall 63 is integrally formed and connected to the front end portion of the tubular portion 62 by the four ribs 636, but is not limited to this configuration.
