Eight spouts 12 are arranged in a substantially straight line in the direction. An operation switch 5 is connected to a wall 3 near the right side of the mist shower device 10 and connected to an electromagnetic valve device 24 built in the mist shower device 10 to be described later to open and close the valve body of the electromagnetic valve device 24. And an operation switch 6 for adjusting the hot water temperature of the mist shower.

  As shown in FIGS. 2 and 3, the mist shower device 10 is screwed and fixed to the wall surface 3, and a vertical rectangular cover 14 is attached to cover substantially the whole. Further, an opening 20 through which the connection port 18 of the water stop cock 16 accommodated in the cover 14 is exposed is provided in the upper part on the back side of the cover 14. A pipe 4 inserted through the opening 20 and routed from the back side of the wall surface 3 is connected to a connection port 18 of the water stop cock 16. In this example, the connection port 18 of the water stop cock 16 corresponds to a “connection port” of the mist shower apparatus according to claim 1.

  The main body of the mist shower device 10 is provided with a stop cock 16, a solenoid valve device 24, and eight ejection devices 26 that are arranged in a substantially straight line in the vertical direction and fixed to the mounting base 11. On the upper part of the mist shower device 10, a water stop cock 16 connected to the pipe 4 as described above and supplied with hot water from the pipe 4 is screwed and fixed. The operation of the stop cock 16 temporarily stops the flow of hot water from the stop cock 16 to the secondary side, and performs maintenance work for each faucet part on the secondary side of the stop cock 16, Furthermore, the solenoid valve device 24 can be opened to drain water for preventing freezing on the secondary side of the stop cock 16 in cold weather. In addition, the operation unit cover body 22 of the cover 14 that covers the stop cock 16 is provided so as to be removable from the cover 14 main body, so that the operation unit cover can be removed without removing the cover 14 main body from the mounting base 11. The hydrant 16 can be operated simply by removing the body 22, and the convenience of the hydrant 16 operation is achieved.

  A solenoid valve device 24 connected to the stop cock 16 is disposed below the stop cock 16. The electromagnetic valve device 24 is driven to open and close by an electric signal generated by the operation of the operation switch 5 described above, and supplies / stops hot water to the ejection device 26 on the secondary side of the electromagnetic valve device 24. The connecting portion 25 of the electromagnetic valve device 24 is fixed to a plate-like stay 23 that is substantially L-shaped when viewed from the side, and this stay 23 is fixed to the mounting base 11 by a fixing bracket 37 and is fixed to the mounting base 11. ing. In addition, a copper pipe 28 to which an ejection device 26 is attached is connected to the secondary side of the electromagnetic valve device 24.

  As shown in FIG. 2 and FIG. 4, the copper pipe 28 is substantially suspended below and connected to the electromagnetic valve device 24. More specifically, the copper tube 28 is gradually lowered toward the rear side of the mist shower device 10 from the connecting portion 25 of the electromagnetic valve device 24 disposed near the front side of the mist shower device 10 toward the lower side of the mist shower device 10. And a straight portion 30 that extends linearly downward along the front side of the mounting base 11. In the straight portion 30, eight ejection devices 26 are arranged in a substantially straight line along the vertical direction of the mist shower device 10, that is, along the axial center of the straight portion 30, toward the front side of the mist shower device 10. . Each of the ejection devices 26 is connected in communication with a copper tube 28. A nozzle holder 32 and a nozzle 34 that is freely supported on the front side of the nozzle holder 32 so that its tip direction can be freely changed with respect to the nozzle holder 32 are provided. Furthermore, a small-diameter jet port 12 for jetting mist-like mist is provided at the tip of these nozzles 34. And it is comprised so that the direction of the mist ejected from the jet nozzle 12 can be changed within the predetermined range by changing the direction of the nozzle 34. Moreover, since this mist shower apparatus 10 has many ejection apparatuses 26 arrange | positioned up and down, the user can fully take mist to the whole body. The copper tube 28 is fixed to the mounting base 11 by fixing brackets 36 at three locations of the straight portion 30.

  As shown in FIG. 5, the copper tube 28 has a substantially circular cross section, and is fixed by a fixing metal fitting 36 having an arc portion 40 adapted to match the outer peripheral surface of the copper tube 28. ing. The fixing bracket 36 includes a holding member 42 provided with the arc portion 40 and a base member 44 that is fixed to the mounting base 11 and to which the holding member 42 is screwed. As described above, the copper tube 28 having a substantially circular cross section is held in the arc portion 40. However, as described above, the upper end portion of the copper tube 28 is eccentric from the axis of the straight portion 30. The bent portion 29 is positioned and fixed and connected to the connecting portion 25 of the electromagnetic valve device 24 fixed by the stay 23. Therefore, the ejection device 26 attached to the straight portion 30 of the copper tube 28 eccentric in this way is straight depending on the positional relationship between the attachment position of the copper tube 28 to the stay 23 and the attachment position to the fixing bracket 36. The direction around the axis of the portion 30 is determined in advance. Note that a plastic tape or the like may be wound around the copper tube 28 where the fixing bracket 36 is attached in order to prevent rattling or displacement of the copper tube 28 after the attachment.

  Since the ejection device 26 can be directed in a predetermined direction as described above, the mist can be ejected from the mist shower device 10 after installation in an appropriate direction. For example, when the pipe to which the ejection device 26 is attached is straight, the pipe can be rotated around the axis even when it is fixed by the fixing bracket 36 or the like, so the direction around the axis is not determined. Therefore, the direction of the ejection device 26 is not limited to an appropriate direction, and complicated work such as fixing the pipe while the direction of the ejection device 26 is directed in an appropriate direction is forced. In this mist shower apparatus 10, since the direction of the ejection device 26 when the copper tube 28 is fixed is fixed as described above, the ejection device 26 is simply fixed to the mounting base 11 or the like. The direction will be determined appropriately.

  Moreover, as shown in FIG. 6, about the jet nozzle 12a located in the uppermost part among these jet nozzles 12, it is arrange | positioned so that the height from the floor surface 2 may be set to 1200 millimeters. The mist from the spout 12a can be ejected at an appropriate height toward the vicinity of the user's shoulder in a standing state, and the mist is not directly applied to the user's face and hair. Moreover, since the seven spouts 12 other than the spout 12a are arranged downward, it is possible to effectively obtain a healing effect and a relaxation effect by taking a mist from the shoulder to the crotch area. The body can be fully exposed to mist. The interval between these jets 12 is provided at 50 mm, and the lowermost jet 12 b is provided at a height of 850 mm from the floor surface 2. Moreover, when the inside of the bathroom 1 is made into a sauna using the mist shower device 10, or when hot water is jetted out to warm the bathroom 1 in advance when the temperature is low, it is provided at an appropriate height. The inside of the bathroom 1 can be quickly warmed up and down the bathroom 1 by the jet nozzle 12.

  As described above, the mist shower apparatus 10 is provided with the connection port 18 to which hot water is supplied from the pipe 4 at the upper portion thereof, and below the connection port 18, the jet port 12 communicated with the connection port 18 is arranged. Therefore, after the mist shower is stopped by closing the flow path by the electromagnetic valve device 24, the lower residual water is naturally discharged from the lower outlet 12 from the electromagnetic valve device 24. Since the residual water is discharged in this way, it is possible to suppress the propagation of germs such as Legionella bacteria in the flow path below the solenoid valve device 24, particularly in the vicinity of the spout 12 that is easily exposed to the atmosphere. In addition, when it is desired to discharge residual water on the secondary side from the stop cock 16 in order to prevent freezing in the cold and to maintain the solenoid valve device 24, the stop cock 16 is closed by operating the stop cock 16. If the solenoid valve device 24 is opened, the remaining water below the stop cock 16 is naturally discharged from the ejection device 26, and it is not necessary to separately operate the drain plug, and the draining operation can be performed very easily. Can do.

  Although the present embodiment is configured as described above, the present invention is not limited to this, and various modifications can be made within the scope of the gist of the present invention. For example, the mist shower device 10 is not limited to the mist shower device 10 attached to the wall surface 3, and if the spout 12 is disposed below the connection port 18, the mist shower device installed directly on the floor surface 2 or suspended from the ceiling surface. It can also be applied to a mist shower device that can be lowered. Further, the mist shower apparatus 10 is provided with eight spouts 12 but may be changed to other numbers. However, in order to discharge the remaining water more smoothly, it is preferable to provide as many jet outlets 12 as possible. Moreover, it is also possible to change the space | interval of each jet nozzle 12. FIG. Moreover, it is not restricted to the aspect in which the stop cock 16 is provided in the mist shower apparatus 10, A stop cock is provided in the middle of the piping 4, It can also apply to the mist shower apparatus in which a stop cock is not incorporated. Further, the present invention can be applied to a mist shower device that does not incorporate a valve device. In this case, the valve device is disposed on the primary side of the mist shower device, and the mist shower is ejected and stopped. From the valve device outside the mist shower device to the connection port 18 of the mist shower device. The remaining water on the secondary side from the uppermost part of the flow path leading to is naturally discharged from the jet outlet after the mist shower is stopped. For example, in the mist shower device 10 of FIG. 6, when a valve device is provided near the primary side of the pipe 4, the residual water is discharged from the portion bent downward near the primary side of the pipe 4 to the primary side. The remaining water on the secondary side is discharged from the spout 12 from the vicinity of the connection port 18.

  Further, the material is not limited to the copper tube 28, but other materials such as piping made of synthetic resin can be used. However, by using the copper tube 28 as in this example, a sterilizing effect by copper ions is also obtained. Therefore, propagation of miscellaneous bacteria can be further suppressed. Further, in the mist shower apparatus 10, the water faucet 16 is aligned and directly connected to the pipe 4 drawn into the bathroom 1 from the back side of the wall surface 3, and the height of the mist shower apparatus 10 is positioned and fixed to the spout 12 a. Although the height from the floor surface is 1200 millimeters, if the pipe 4 is not drawn into such a position, the connection from the opening of the pipe 4 to the stop cock 16 is connected using another connecting pipe. And you may make it the height of the jet nozzle 12a become 1200-1250 millimeters. Moreover, it is good also as providing the height of the jet nozzle 12a itself with respect to the mist shower apparatus 10 main body so that adjustment is possible, and adjusting the height of the jet nozzle 12a suitably.
