The plug 17 a is fixedly connected to the other end 15 c of the on-off valve 15, and the socket 17 b is fixedly connected to one end of the curl hose 19. 3 and 4, the on-off valve 15 and the curl hose 19 are connected in communication by connecting the plug 17a and the socket 17b. The plug 17a and the socket 17b can be connected by inserting the plug 17a into the socket 17b in a straight line (in the present embodiment, along a straight line parallel to the axis P direction). Further, by pulling out the socket 17b from the plug 17a in a straight line (in the present embodiment, along a straight line parallel to the axis P direction), the both are separated and the on-off valve 15 and the curl hose 19 are separated from each other. Can do.

  Further, as shown in FIG. 3, the branch pipe portion 13 and the on-off valve 15 including the joint member 17 are sandwiched between both ends 12 a and 12 b of the main pipe portion 12 with respect to the axial center P direction of the main pipe portion 12. They are arranged so as to be within the range C.

  The curl hose 19 is a flexible resin pipe and is wound in a coil shape. For this reason, it is hard to get entangled and is excellent in elasticity. Further, the outer diameter of the curl hose 19 is smaller than the outer diameter of the branch pipe portion 13, and the curl hose 19 is easier to handle when it is expanded and contracted. The total length of the curl hose 19 is preferably about 5 m to 7 m, for example. The curl hose 19 corresponds to the flexible tube in this invention.

  The plug 21 and the socket 22 are provided between the other end side (primary side) of the curl hose 19 and the flow meter with valve 23. Each of the plug 21 and the socket 22 has the same structure as the plug 17a and the socket 17b described above. The curl hose 19 and the flowmeter with valve 23 are detachably connected by a plug 21 and a socket 22.

  The flow meter with valve 23 is configured by combining an area type flow meter and a needle type valve, and can measure the flow rate of carbon dioxide gas and finely adjust the flow rate. The flow rate of the carbon dioxide gas adjusted by the valved flow meter 23 is preferably in the range of 10 liters / min to 15 liters / min. The flow meter with valve 23 corresponds to a flow meter in the present invention and also corresponds to a flow control valve.

  The decompressor 25 is connected in communication with the primary side of the valve-equipped flow meter 23. A pressure gauge 27 is attached to the decompressor 25. The decompressor 25 reduces the carbon dioxide gas to a desired pressure. The pressure at which the pressure is reduced by the pressure reducer 25 is preferably a value within a range from 0.2 MPa to 0.3 MPa. The pressure gauge 27 measures the pressure on the primary side of the decompressor 25 (that is, the internal pressure of the cylinder 29).

  The cylinder 29 is connected in communication with the primary side of the decompressor 25. The cylinder 29 stores compressed carbon dioxide gas. Examples of the size of the cylinder 29 include 1 kg to 5 kg.

  Next, operation | movement of the mixed water production | generation apparatus 1 which concerns on an Example is demonstrated. Here, the pressure reducing device 25 and the needle type valve of the flow meter with valve 23 are set in advance so that the pressure and flow rate of the carbon dioxide gas become desired values, and the on-off valve 15 is closed. To do.

  First, the lever 4 a of the water tap 4 is operated to feed water to the pipe 6. Thereby, water supply flows from the one end 12a of the main pipe part 12 to the other end 12b. Water supplied from the other end 12b is discharged from the shower head 5 through the shower hose 7 as it is.

  Here, when it is desired to discharge the mixed water, the on-off valve 15 is opened by operating the handle portion 15a. As a result, carbon dioxide gas is mixed into the main pipe section 12 at a predetermined pressure and a predetermined flow rate. The mixer 11 mixes carbon dioxide with feed water to generate mixed water, and sends the generated mixed water to the shower hose 7. The mixed water sent to the shower hose 7 is discharged through the shower head 5. In addition to the effect of promoting blood circulation, the discharged mixed water has a higher effect of cleaning sebum and the like, and a bactericidal effect compared to the water supply itself. For this reason, work, such as favorable hair washing, can be performed efficiently.

  Moreover, when switching from mixed water to water supply, the handle part 15a is operated and the on-off valve 15 is closed. Thereby, carbon dioxide gas does not mix in the main pipe part 12, and the mixer 11 sends out water supply to the shower hose 7 as it is. The water supplied to the shower hose 7 is discharged through the shower head 5.

  Here, when the shower head 5 is appropriately pulled out from the ball 3, the shower hose 7 appropriately follows the movement of the shower head 5. However, the mixer 11 and the on-off valve 1 are fixed to the pipe 6 and do not move.

  Thus, according to the mixed water production | generation apparatus 1 which concerns on an Example, while the mixer 11 has a simple structure, since other structures, such as the on-off valve 15 etc., can employ | adopt general-purpose products, the mixed water production | generation apparatus 1 whole Can have a simple structure. For this reason, the manufacturing cost of the mixed water production | generation apparatus 1 can be reduced. Moreover, since the mixed water production | generation apparatus 1 can be installed only by interrupting the both ends 12a and 12b of the main pipe part 12 between water supply systems, the mixed water production | generation apparatus of a present Example is used later with respect to the existing water supply equipment etc. 1 can be easily added.

  Moreover, since the one end 13a of the branch pipe part 13 is inserted into the main pipe part 12, the bent part 13b of the branch pipe part 13 can be suitably brought close to the side part 12c of the main pipe part 12. And thereby, the other end 13c side of the branch pipe part 13 and the main pipe part 12 can be made to adjoin suitably. Since the other end side 13c of the branch pipe part 13 is substantially parallel to the main pipe part 12, the mixer 11 and the on-off valve 15 are installed in a narrow place such as near the bottom of the ball 3 as shown in FIG. In addition, the handle portion 15a of the on-off valve 15 can be easily operated directly.

  Further, the internal thread part 12d formed on the inner wall of the through hole B of the main pipe part 12 and the external thread part 13d formed on the branch pipe part 13 are screwed together, so that the main pipe part 12 and the branch pipe part 13 are connected. It is connected. Thus, since the simple structure is employ | adopted, size reduction of the branch pipe part 13 can be achieved further.

  Further, the branch pipe part 13 is connected to a position biased to one end 12 a of the main pipe part 12, and the other end 13 c of the branch pipe part 13 extends toward the other end 12 b side of the main pipe part 12. 11 can be prevented from being longer than the main pipe portion 12 in the axial center P direction.

  Moreover, since the on-off valve 15 is arrange | positioned in the range C between the both ends 12a and 12b of the main pipe part 12 with respect to the axial center P direction, the mixer 11 and the on-off valve 15 can be made compact. Similarly, since the joint member 17 is also disposed in the range C between both ends 12a and 12b of the main pipe portion 12 with respect to the direction of the axis P, the pipe 6 is connected to one end 12a or the other end 12b of the main pipe portion 12. When the work for attaching or detaching the shower hose 7 is performed, the joint member 17 or the like does not hinder the work. Since the curl hose 19 connected to the joint member 17 is freely bendable, it can be moved to a position where it does not interfere with the above operation. Furthermore, since the joint member 17 is composed of a plug 17a and a socket 17b that can be inserted and removed linearly, the on-off valve 15 and the curl hose 19 can be easily attached and detached even when the main pipe portion 12 is close. it can.

  Moreover, since the decompressor 25 is provided, the carbon dioxide gas can be supplied to the mixer 11 at an appropriate pressure. Moreover, since the flowmeter 23 with a valve is provided, the measurement of the flow rate of carbon dioxide gas and the fine adjustment of the flow rate can be easily performed. In the case where the mixer 11 and the flowmeter 23 with a valve are set in advance, the carbon dioxide gas having a desired pressure can be supplied to the mixer 11 at a desired flow rate simply by opening the on-off valve 15.
