The joint 102 inserted through the insertion hole 326 is fixed to the bracket 104 with screws 324 (see FIGS. 9, 17, and 18).
As shown in these figures, the faucet mechanism portion 76, the body shower water discharge portion 20, the joint 102 for the overhead shower water discharge portion 18, and the internal function portion 78 including a number of pipes connecting them to each other include a bracket 98. , 100, 104 are fixed to the rear surface side (wall W side), and the brackets 98, 100, 104 are mounted in a state in which the internal function part 78 is inserted into the case body 14 from the open part of the front surface of the case body 14. Are fixed to the front side portion of the case body 14, that is, the open side portion.

That is, by fastening and fixing the brackets 98, 100, and 104 to the case main body 14 in this way, the entire internal function unit 78 including internal pipes to be described later is preliminarily assembled, that is, the case main body 14 in a unit state. It is fixed to.
As shown in FIG. 11, the upper wall 14C of the case body 14 is configured separately from the rear wall 14A and the side wall 14B, and is fixed to the rear wall 14A and the side wall 14B with screws 112.
Specifically, as shown in FIG. 11, the upper ends of the reinforcing ribs 116 in which the screws 112 are inserted downward into the fastening holes 114 of the upper wall 14C and are provided vertically along the rear wall 14A and the side wall 14B. The upper wall 14C is fastened and fixed to the rear wall 14A and the side wall 14B.

FIG. 4 shows the configuration of the internal function section 78 as a systematic diagram together with the body shower water discharge section 20, the overhead shower water discharge section 18, the hand shower water discharge section 24, the water discharge pipe 22, and the like.
In the figure, A1 and A2 are pipes for internal water supply and hot water supply connected to the water supply main pipe P1 and hot water supply main pipe P2 on the back of the wall through a stop cock 118, and the ends are connected to a mixing valve 88 for hot water. Water and hot water are supplied to the mixing valve 88 through the pipes A1 and A2, respectively.

The mixing valve 88 mixes the supplied water and hot water at a predetermined ratio in accordance with the operation of the operation unit 48 of FIG. 1 to obtain temperature-controlled water (temperature-controlled hot water) at an appropriate temperature.
The temperature control water from the mixing valve 88 is sent to the overhead shower water discharger 18 via the pipe B, the switching valve 90 for the overhead shower water discharger 18 and the pipe J, and is discharged from the shower hole 32.

In this embodiment, when the switching valve 90 is in the shower water discharge position, the pipe B and the pipe J are in communication with each other, and the temperature-controlled water from the mixing valve 88 is sent to the shower head water discharge unit 18 and from there. Shower water is discharged.
On the other hand, when the switching valve 90 is in the water stop position, the pipe B and the pipe J are cut off, and the temperature-controlled water from the mixing valve 88 is not supplied to the overhead shower water discharger 18.

On the other hand, when the indicator 52 of FIG. 1 in the switching valve 90 is in the upward position, that is, in the temperature confirmation position, the pipe B is disconnected from the pipe J, while being in communication with the pipe E, the mixing valve Water from 88 is branched into pipe E.
The water branched into the pipe E is sent to the water discharge pipe 22 through the cold water drain valve 96 and discharged from the water discharge pipe 22 downward.
At this time, the water in the pipe J is also drained from the cold water drain valve 96 to the pipe D side through the pipe C, and is discharged downward from the water outlet 34 of the water discharge pipe 22 via the pipe D.

In this embodiment, the pipe E, the pipe C, and the cold water drain valve 96 have the following meanings.
When the shower apparatus 10 is used without being used for a certain period of time, the water in the hot water supply main pipe P2 extending from the hot water supply source such as a hot water heater is in a cooled state, that is, a cold water state.
Further, the water in the pipe J on the overhead shower water discharger 18 side is also in a cold water state due to cooling by being left for a long time.
Therefore, when the switching valve 90 is operated in this state and water discharge is started from the overhead shower water discharger 18, cold water in the pipe J (residual water in the pipe) and cold water in the pipe P2 (cold water in the pipe) are showered. End up.

Therefore, in this embodiment, the operation unit 44 is positioned at the temperature confirmation position, whereby the pipe B and the pipe E are first brought into a communication state.
In this state, the water from the mixing valve 88 branches and flows from the pipe B to the pipe E, and the chilled water drain valve 96 is opened by the flow from the pipe E, and the chilled water flowing through the pipe E is supplied to the pipe F. , It is discharged outside through the water discharge pipe 22.
When the cold water drain valve 96 is opened, the pipe C and the pipe D are in communication with each other at the same time, and the cold residual water remaining in the pipe J on the overhead shower water discharge unit 18 side is the pipe C and the cold water drain valve 96. , Flows through the pipe D and is discharged from the water discharge pipe 22 to the outside.
Then, when the cold water and the residual water in the pipe in the cold water state are discharged and the warm temperature-controlled water is sent out from the mixing valve 88, the temperature is adjusted from the overhead shower water discharge unit 18 by switching the switching valve 90 to the shower water discharge position. Water can be discharged from the shower.

FIG. 5 shows the configuration of the cold water drain valve 96 along with its operation. As shown in the figure, this cold water drain valve 96 has a valve body 121 inside the valve body 120.
The valve body 121 includes a first valve section 122, a second valve section 124, and a connecting shaft 126 that connects them. The first valve section 122 and the second valve section 121 are moved by the upward movement of the valve body 121 in the drawing. The valve part 124 opens upwardly away from the corresponding first valve seat 128 and second valve seat 130.
When the first valve section 122 is opened, the flow paths 132 and 134 are in communication with each other, and when the second valve section 124 is opened, the flow paths 136 and 138 are in communication with each other.
When the water from the mixing valve 88 flows upward in the drawing into the flow path 132 through the pipe E, the cold water drain valve 96 opens the first valve portion 122 formed of a diaphragm valve by the pressure of the water supply. The cold water that has flowed through is circulated from the channel 132 to the channel 134. The water that has flowed into the flow path 134 then flows into the pipe F.

When the first valve section 122 is opened, the second valve section 130 is also opened, and the flow path 136 and the flow path 138 are brought into communication with each other by opening the second valve section 130.
The communication between the flow paths 136 and 138 causes the cold residual water in the pipe J to flow into the cold water drain valve 96 through the pipe C, and the flowed residual water flows from the flow path 138 to the pipe D. Finally, the water is discharged from the water discharge pipe 22 to the outside.
The valve body 121 is always biased to the closed state by the coil spring 140 and is kept closed when the supply water pressure is not guided to the chilled water drain valve 96 through the pipe E.

The temperature control water from the mixing valve 88 is also led to the pipes I1 and I2 via the switching valve 92 for the pipe B and the body shower water discharger 20 as shown in FIG. From 20A-5 and 20B-1 to 20B-5, shower water is discharged as a mist shower.
Specifically, when the operation unit 46 for the body shower water discharger 20 is positioned at the shower water discharge position, the switching valve 92 brings the pipe B and the pipes I1 and I2 into communication, and the temperature adjustment water from the mixing valve 88 is adjusted. The shower water is discharged from the body shower water discharge portions 20A-1 to 20A-5 and 20B-1 to 20B-5, which are guided to the pipes I1 and I2 and communicate with the pipes I1 and I2.
On the other hand, when the operation unit 46 is switched to the water stop position, the pipe B and the pipes I1 and I2 are cut off, and the shower water discharge from the body shower water discharge unit 20 is stopped.

In this embodiment, as shown in FIG. 1, the operation part 46 for the body shower water discharger 20 can also be switched to the temperature confirmation position, and when the switching operation is performed, the switching valve 92 is shown in FIG. The piping B and the piping K are brought into a communication state.
At this time, the pipe B is in communication with the pipe E through the pipe K. Therefore, in this state, the cold water from the mixing valve 88 flows into the pipe E through the pipe K, and the cold water is the same as described above. It is discharged to the outside through the drain valve 96.

A pipe G communicating with the hand shower water discharger 24 and a pipe H communicating with the water discharge pipe 22 are also connected to the pipe B via the switching valve 94.
Then, the operation valve 50 is operated to switch the switching valve 94 so that the pipe B and the pipe G communicate with each other, whereby the temperature control water from the mixing valve 88 is guided to the hand shower water discharger 24, and the shower hole 40. From the shower.
On the other hand, when the switching valve 94 is switched to a state in which the pipe B and the pipe H are in communication with each other, the temperature adjustment water from the mixing valve 88 flows from the pipe B to the pipe H and is discharged downward from the water outlet 34 of the water discharge pipe 22. The

In this case, the work for positioning the body shower water discharger 20 can be omitted, and the number of man-hours required for the production of the shower device 10 can be reduced.

  In addition, when installing the shower device 10 on the wall surface W at the construction site, it is not necessary to fix the body shower water discharge unit 20 separately from the faucet mechanism unit 76, thereby reducing the labor of the construction. The installation workability can be further improved.

  In particular, in the present embodiment, the entire internal function portion 78 is fixed to the bracket 98 and the brackets 100 and 104 which are separate from the bracket 98, and the entire internal function portion 78 is formed as one unit together with the brackets 98, 100 and 104. Since all of them are fixed to the case 12 in the state of spare assembly, compared to the case where a large number of functional parts and pipes constituting the internal functional unit 78 are individually attached to the case 12, Attachment to the case 12 can be performed very easily.

  Furthermore, in this embodiment, the internal function part 78 including the faucet mechanism part 76 is fixed to the rear surface side of the brackets 98, 100, 104, and is inserted into the case body 14 from the opening part on the front surface. Thus, since the bracket 98 is fixed to the open portion side of the case main body 14, the internal function portion 78 can be easily mounted and fixed in the case 12 in an assembled state.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the above-described embodiment, the front portion of the case 12 having a box shape is used as the front cover 16, and the case main body 14 having a U-shaped rear cross section is separated from the case main body 14. The internal function unit 78 is assembled from the side, but it is also possible to assemble the internal function unit 78 from these parts with the side surface or the rear surface as an open part in some cases.
The faucet mechanism 76 is merely an example, and the faucet mechanism 76 can be configured in various other forms including a hot and cold mixing valve and a switching valve. Then, according to circumstances, it is possible to fix only the faucet mechanism part to the case with a bracket, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
