Description

The present invention relates to a water discharge device installed along a wall surface.

Conventionally, there is a water discharge device installed along the wall surface. This water discharge device is provided, for example, in a shower device in which the shower head is supported via a support column or the like extending in the vertical direction along the wall surface, and includes an adjustment mechanism for adjusting the water discharge flow rate and the water temperature. When such a water discharge device is attached to a wall surface, an adapter (water supply leg) for connecting to a water supply joint inside the water discharge device is attached to a pipe (water supply pipe, hot water supply pipe) embedded in the wall surface. There is a need.

Regarding the adapter of the water discharge device, for example, a technique has been proposed in which a bag nut is screwed into a male screw formed in the middle of each adapter (water supply adapter, hot water supply adapter) to fix each adapter and the water supply joint. (See, for example, Patent Document 1).

In the above-mentioned conventional technique, the inter-core adjustment can be performed by adjusting the rotation position of each adapter. However, there is a possibility that an error may occur in the piping inside the wall surface depending not only on the distance between the cores but also on the buried amount (or protruding amount) in the wall surface direction and the product tolerance to be installed.

In this way, if the installation position of each adapter varies, the connection position between the adapter and the water supply joint inside the water discharge device varies with respect to the wall surface direction. At this time, if the distance between the water discharge device and the wall surface becomes too close, there is a risk that they will interfere and cannot be attached. However, if the water spouting device is installed so that it can be installed without fail, a gap may be generated between the water spouting device and the wall surface, which may deteriorate the design.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a water discharge device capable of suppressing the occurrence of a gap between the wall surface and the wall surface and improving the design. ..

Specifically, the water supply leg or the water supply joint is fixed by fixing the other of the water supply leg or the water supply joint to the flanged nut provided so as to be relatively movable with respect to either the water supply leg or the water supply joint. By fixing the water supply joint and the water supply joint, the relative position of the water discharge device with respect to the water supply leg (wall surface) can be adjusted.

In another aspect of the water spouting device according to the present invention, in the water spouting device, the water supply leg and the water supply joint communicate with each other in a state where one end of the water supply leg and the water supply joint is inserted into the other.

In addition, it becomes easy to secure the flow path area in the water supply joint and the water supply leg. The water supply joint provided inside the water discharge device has size restrictions and cannot be formed too large. Therefore, if the water supply leg is inserted into the water supply joint side, it is necessary to form the water supply leg side to be thinner, and as a result, the cross-sectional area of the flow path becomes smaller. On the contrary, by adopting a structure in which the water supply joint is inserted into the water supply leg, the shaft can be sealed while securing the cross-sectional area of the flow path of the water supply joint.

Another aspect of the water spouting device according to the present invention is that in the water spouting device, the fixing means is a quick fastener.

According to the water discharge device having such a configuration, the water supply leg and the water supply joint can be easily fixed.

According to the present invention, the generation of a gap between the wall surface and the wall surface can be suppressed, and the design can be improved.

Since the configurations of the water supply legs 250, the water supply joint 350, and the quick fastener 450 are substantially the same as the configurations of the water supply legs 200, the water supply joint 300, and the quick fastener 400, some of the illustrations and explanations thereof are omitted here. To do.

First, the water supply legs 200 are attached to the hot water supply pipe (not shown) embedded in the wall surface on which the shower device 100 is installed, and the water supply pipe (not shown) embedded in the wall surface W on which the shower device 100 is installed. Attach the water supply leg 250 to. For example, a female screw portion is provided at each opening (water supply leg connection portion) of the water supply pipe and the hot water supply pipe. Then, the male screw portion 211 provided at the upstream end portion 210 of the water supply leg 200 is screwed into the female screw portion of the hot water supply pipe, and the water supply leg 200 is attached to the hot water supply pipe. Similarly, the male screw portion provided at the upstream end of the water supply leg 250 is screwed into the female screw portion of the water supply pipe, and the water supply leg 250 is attached to the water supply pipe.

Next, by adjusting the rotational positions of the water supply legs 200 and 250 using a mounting jig (not shown), the central axis A2 of the downstream end portion 230 of the water supply leg 200 and the downstream end portion of the water supply leg 250 Adjust the distance from the central axis of the jig to a predetermined distance.

Here, the mounting jig (not shown) is configured so that two columnar portions project from the elongated flat plate portion. The two cylindrical portions are formed to have a thickness that allows them to be inserted into the downstream end portion 230 of the water supply leg 200 and the downstream end portion of the water supply leg 250 without any gap. Further, the distance between the two cylindrical portions (the distance between the central axes) is the same as the distance between the central axes of the water supply joints 300 and 350 installed inside the water discharge device 110. Therefore, the rotational positions of the water supply legs 200 and 250 are adjusted so that the two cylindrical portions of the mounting jig are simultaneously inserted into the downstream end portion 230 of the water supply leg 200 and the downstream end portion of the water supply leg 250. As a result, the distance between the downstream end 230 of the water supply leg 200 and the downstream end of the water supply leg 250 can be adjusted to a predetermined distance. Further, by adjusting the rotation positions of the water supply legs 200 and 250 so that the flat plate portion of the mounting jig is directed in the vertical direction, the downstream end portion 230 of the water supply leg 200 and the downstream end portion of the water supply leg 250 As the interval becomes a predetermined interval, the downstream end portion 230 of the water supply leg 200 and the downstream end portion of the water supply leg 250 are aligned in the vertical direction.

By inserting the two cylindrical portions protruding from the mounting jig into the pipes of the downstream end portion 230 of the water supply leg 200 and the downstream end portion of the water supply leg 250 in this way, the water supply legs 200 and 250 Adjust the rotation position.

Next, each part of the shower device 100 is fixed at a predetermined position on the wall surface W with screws 11 to 14 (see FIG. 2) or the like. In this case, the bottom cover 114 (see FIG. 2) of the water discharge device 110 is removed from the water discharge device 110. Further, the shaft seal portion 311 of the upstream end portion 310 of the water supply joint 300 is inserted into the opening 233 of the downstream end portion 230 of the water supply leg 200, and the upstream end of the water supply joint 350 is inserted into the opening of the downstream end portion of the water supply leg 250. Arrange so that the shaft seal part at the end is inserted.

Next, from the lower side of the water discharge device 110, the flanged nut 330 of the water supply joint 300 is rotated to move the flanged nut 330 in the axial direction, and the end face 332 of the flanged nut 330 and the downstream end of the water supply leg 200 are moved. Adjust so that the end surface 232 of the portion 230 comes into contact with the end surface 232. Similarly, by rotating the flanged nut of the water supply joint 350, the flanged nut is moved in the axial direction, and the end face of the flanged nut of the water supply joint 350 comes into contact with the end face of the downstream end of the water supply leg 250. Adjust so that.

Next, from the lower side of the water discharge device 110, the end surface 332 of the flanged nut 330 and the end surface 232 of the downstream end portion 230 of the water supply leg 200 are in contact with each other, and the flange portion 331 of the flanged nut 330 is contacted. The quick fastener 400 is inserted so as to sandwich the flange portion 231 of the water supply leg 200. In this case, make sure to insert the Quick Fastener 400 until it clicks. By inserting the quick fastener 400, the flange portion 331 of the flanged nut 330 and the flange portion 231 of the water supply leg 200 are fixed by the engagement grooves 441 and 442 of the quick fastener 400. Then, the quick fastener 400 is rotated about 90 degrees with the shaft of the downstream end 230 of the water supply leg 200 (the shaft of the water supply joint 300) as a rotation shaft. Here, since the nut 330 with a flange and the water supply joint 300 are fixed with screws, the water supply leg 200 and the water supply joint 300 are connected by fixing the water supply leg 200 and the nut 330 with a flange with the quick fastener 400. It will be relatively fixed. For example, as shown in FIGS. 12 to 14, the water supply leg 200 and the water supply joint 300 are fixed by the quick fastener 400.

Similarly, from the lower side of the water discharge device 110, the collar portion of the flanged nut of the water supply joint 350 is in contact with the end face of the flanged nut of the water supply joint 350 and the end face of the downstream end portion of the water supply leg 250. And the quick fastener 450 is inserted so as to sandwich the flange of the water supply leg 250. In this case, make sure to insert the Quick Fastener 450 until you hear a click. By inserting the quick fastener 450, the flange portion of the flanged nut of the water supply joint 350 and the flange portion of the water supply leg 250 are fixed by the engagement groove portion of the quick fastener 450. Then, the quick fastener 450 is rotated about 90 degrees with the shaft at the downstream end of the water supply leg 250 (the shaft of the water supply joint 350) as a rotation shaft. In this case, the quick fastener 400 is rotated in the direction opposite to the rotation direction. That is, in the water discharge device 110, the quick fastener 400 and the quick fastener 450 are arranged so that the opening 420 of the quick fastener 400 and the opening of the quick fastener 450 face each other (to face each other inward). In other words, in the water discharge device 110, the quick fastener 400 and the quick fastener 450 are arranged so that the recess 410 of the quick fastener 400 and the recess of the quick fastener 450 face opposite to each other (to face each other outward). To. For example, as shown in FIG. 2, the water supply leg 250 and the water supply joint 350 are fixed by the quick fastener 450.

Next, the lower surface cover 114 is attached to the lower portion of the water discharge device 110. By attaching the lower surface cover 114 to the lower portion of the water discharge device 110 in this way, the space in which the quick fasteners 400 and 450 can move is limited around the quick fasteners 400 and 450. Therefore, it is possible to prevent the quick fasteners 400 and 450 from rotating or coming off. In this way, when the water discharge device 110 has a substantially flat plate shape like a box, there are upper and lower restrictions on the water discharge device 110, and these restrictions should be used to prevent rotation and detachment of the quick fasteners 400 and 450. Can be done.

Here, if the position of the water supply joint is not adjusted with respect to the water supply leg, a gap is generated between the wall surface on which the water discharge device is installed and the water discharge device, which may deteriorate the design. Therefore, in the present embodiment, the position of the water supply leg 200 and the water supply joint 300 can be adjusted by providing the nut 330 with a flange that can move relative to either the water supply leg 200 or the water supply joint 300. .. Since the position can be adjusted in this way, it is possible to suppress the occurrence of a gap between the shower device 100 and the wall surface.

That is, when the box-shaped water discharge device 110 is closely attached to the wall surface, it is possible to realize a mechanism capable of absorbing the error in attaching the water discharge device 110 and the water supply legs 200 and 250 on the water discharge device 110 side. .. In other words, it is possible to realize a fixed structure for preventing the occurrence of a gap between the water discharge device 110 covered with the cover and the wall surface. As a result, it is possible to realize the shower device 100 that fits the bathroom wall surface exactly.

As described above, in the present embodiment, leg members (water supply legs 200, 250) capable of adjusting between the cores are provided, and a collared nut (flammed nut 330, flanged nut of the water supply joint 350) is provided on the water discharge device 110 side. ) Is provided, and the collar part of the collared nut (the collar part 331 of the collared nut 330, the collar part of the collared nut of the water supply joint 350) and the collar part of the leg members (water supply legs 200, 250) (flange portion 231 and water supply). The brim of the leg 250) can be fastened with the quick fasteners 400 and 450.

In the present embodiment, an example is shown in which a shaft seal portion is provided at the end of the water supply joint and the shaft seal portion is inserted into the opening of the water supply leg, but the present invention is not limited to this. For example, a shaft seal portion may be provided at the end of the water supply leg, and the shaft seal portion may be inserted into the opening of the water supply joint.

Further, in the present embodiment, an example is shown in which a nut with a collar is provided on the water supply joint and the collar portion of the nut with a collar and the flange portion of the water supply leg are fixed, but the present invention is not limited thereto. For example, a nut with a collar may be provided on the water supply leg, and a collar may be provided at the end of the water supply joint to fix these flanges to each other. In this way, the present embodiment can be realized by providing a flanged nut that can move relative to the water supply leg and the water supply joint on one of the water supply joint and the water supply leg.

However, according to the configuration in which the nut with a flange is provided on the water supply joint as in the present embodiment, the water supply joint and the water supply leg are connected in communication with the water supply joint side inserted into the water supply leg. Become. This makes it easy to secure the flow path diameter in the water supply joint and the water supply leg. That is, the water supply joint provided inside the casing has a relatively low degree of freedom regarding the pipe diameter from the viewpoint of avoiding interference with other devices and reducing the size of the water discharge device 110, whereas the water supply is provided. As for the legs, the degree of freedom regarding the pipe diameter is relatively high. For this reason, in the case where the water supply leg is inserted into the water supply joint, the pipe diameter of the water supply leg is limited by the pipe diameter of the water supply joint, and a sufficiently large pipe diameter should be secured as a whole. Can be difficult. Therefore, according to the configuration in which the water supply joint is inserted into the water supply leg, it becomes easy to increase the pipe diameter of the water supply leg, and it becomes relatively easy to secure the flow path area in the water supply leg and the water supply joint.

Further, in the present embodiment, an example in which the quick fastener is used as the fixing means for fixing the flange portion on the water supply leg side and the flange portion on the water supply joint side is shown, but other fixing means may be used. For example, bolts and nuts may be used as fixing means for fixing the flange portion of the water supply leg and the flange portion of the water supply joint. However, when fasteners such as bolts and nuts are used as the fixing means, the space inside the casing of the water discharge device 110 is limited from the viewpoint of miniaturization of the device, so that the work space for fastening the fasteners is limited. It becomes difficult to secure. In this respect, according to the configuration using the quick fastener as in the present embodiment, a work space is not particularly required, and the flanged nut can be easily and surely fixed to the water supply leg.

Further, in the present embodiment, an example is shown in which a shaft seal portion is provided at the end of the water supply joint and the shaft seal portion is inserted into the opening of the water supply leg to ensure watertightness between the water supply leg and the water supply joint. However, the present invention is not limited to this. For example, a surface seal is provided between the end face of the collar on the water supply joint side (the collar of the nut with a collar) and the end face of the collar of the water supply leg (for example, a flat packing is sandwiched between those end faces). Therefore, the watertightness between the water supply leg and the water supply joint may be ensured. However, in this case, in order to ensure watertightness, it is preferable to fix the collars with fixing means such as bolts so that the collars do not loosen. Further, in order to ensure watertightness, it is preferable to perform a sealing treatment between the water supply joint and the nut with a flange. Therefore, from the viewpoint of ensuring sufficient watertightness with a simple structure, as in the present embodiment, a configuration in which one end of the water supply leg and the water supply joint is inserted into the other and connected to each other. Is preferable.

Finally, the description of each of the above-described embodiments is an example of the present invention, and the present invention is not limited to the above-mentioned embodiments. Therefore, it goes without saying that various changes can be made according to the design and the like as long as the technical idea of the present invention is not deviated from the above-described embodiments.
