It has been proposed to provide a contact for displacement control.

JP, 2011-89289, A

  According to the verification by the inventor of the present invention, it has been confirmed that, in the configuration disclosed in Patent Document 1, the displacement control by the contact portion does not function sufficiently, and a problem such as water leakage may occur due to the displacement by the water supply pressure.

  Specifically, it is a water discharger attached to the wall side on the rear side, and includes a water discharge port for shower opening downward, and an elbow flow path for guiding water from a water supply source in the wall surface to the shower water discharge port. In the water spouting device, when water spouting from the shower spout is instantaneously stopped, a strong force called a so-called water hammer acts on the elbow flow path. In particular, it is known that when the shower head connected to the shower spout is provided with a click shower function and when the water spouting is stopped instantaneously by the function, this force is greater.

  In the configuration disclosed in Patent Document 1, such a strong force can not be sufficiently countered, and the elbow flow path is displaced in the vertical direction, and as a result, problems such as water leakage occur. Sometimes.

  The present invention has been made based on the above findings. An object of the present invention is a water discharger mounted on the wall side on the rear side, comprising: a water discharge port opening downward, and an elbow flow path for guiding water from a water supply source in the wall surface to the water discharge port; An object of the present invention is to provide a water discharger capable of reliably preventing displacement of the flow path in the vertical direction.

  The present invention is a water discharge apparatus mounted on a wall surface on the rear side, and includes a water discharge port opening downward, a flow path for guiding water from a water supply source in the wall surface to the water discharge port, and an upper side of the flow path. An upper plate member disposed in the housing, the flow path having a horizontal flow path extending in the horizontal direction, and an elbow flow path connecting the horizontal flow path and the water discharge port, The upper plate member is a water discharge device characterized in that it has a hardened portion formed of a bent portion on the rear side of the elbow flow passage.

  In the water discharge device according to the present invention, when water discharge from the water discharge port is stopped instantaneously, a strong force called a so-called water hammer acts on the elbow flow path, and the elbow flow path tends to be displaced in the vertical direction. However, in the water discharger according to the present invention, the upper plate member disposed on the upper side of the elbow flow passage has a hardened portion formed of a bent portion to sufficiently receive the force acting on the elbow flow passage. Can.

  In addition, since the hardened portion including the bent portion is disposed rearward of the elbow flow path, the degree of freedom in the design of the arrangement position of the water discharge port is not hindered. For example, when the water outlet is a shower water outlet, there is no problem in the arrangement of the shower hose.

  Generally, the upper plate member has a substantially rectangular shape in a plan view. The substantially rectangular shape also includes a partially missing rectangular shape and the like.

  Preferably, the hardened portion is formed along the longitudinal direction of the upper plate member. Such an arrangement of the cured portion can effectively increase the strength of the upper plate member.

  Specifically, the hardening portion may be configured of a first bending portion bending downward from the horizontal direction, and a second bending portion bending so as to return from the first bending portion in the horizontal direction. These bent portions are generated by bending, and the effect of work hardening can be obtained by the bending. Moreover, it is avoided that the thickness of the whole water discharging apparatus becomes thick by bending a 1st bending part below.

  A stopcock may be provided in the flow path. In this case, the hardened portion is preferably located rearward of the front end edge of the water stop valve. According to this, since the hardened portion formed by the bent portion of the upper plate member is disposed in the dead space above the water blocking valve, the entire water discharger can be miniaturized (space saving).

  In addition, a temperature control function unit may be provided in the flow path. Since the temperature control functional unit may include large element members, the upper plate member may be provided with a recess for housing at least a part of the temperature control functional unit in order to effectively store them. preferable. In this case, it is preferable that a relief portion be provided in a region where the extending direction of the curing portion intersects with the extending direction of the recess so that the processing of the curing portion and the processing of the recess do not interfere. The escape portion can be formed, for example, by punching a hole in the upper plate member.

  According to the present invention, since the upper plate member disposed on the upper side of the elbow flow passage has the hardened portion formed of the bent portion, the force acting on the elbow flow passage can be sufficiently received. In addition, since the hardened portion including the bent portion is disposed rearward of the elbow flow path, the degree of freedom in the design of the arrangement position of the water discharge port is not hindered. For example, when the water outlet is a shower water outlet, there is no problem in the arrangement of the shower hose.

(Action effect)
In the water faucet device 1 (water discharge device) according to the present embodiment as described above, when water discharge from the water discharge ports 41 and 42 is stopped instantaneously, a strong force called a so-called water hammer acts on the elbow flow passage 46e, The elbow flow passage 46 e tends to be displaced in the vertical direction. However, in the water faucet device 1 according to the present embodiment, the upper plate member 50 disposed on the upper side of the elbow flow passage 46e has the hardened portion 51 including the bending portions 51a and 51b, whereby the elbow flow passage 46e is formed. Can be well received.

  Moreover, since the hardening part 51 of this embodiment is arrange | positioned behind the elbow flow path 46e, the freedom degree of design of the arrangement position of the water discharge port 41, 42 is not inhibited. Accordingly, no problem occurs in the arrangement of the shower hose 43.

  Moreover, since the hardening part 51 of this embodiment is formed along the longitudinal direction of the upper plate member 50, the intensity | strength of the upper plate member 50 can be increased effectively.

  In addition, the cured portion 51 according to the present embodiment includes a first bent portion 51a bent downward from the horizontal direction, and a second bent portion 51b bent so as to return from the first bent portion 51a in the horizontal direction. Although, these bends can be generated by bending. That is, the effect of work hardening by the said bending process can be acquired. Moreover, it is avoided that the thickness of the faucet apparatus 1 whole becomes thick by bending the 1st bending part 51a below.

  And as shown in FIG. 16, the hardening part 51 is located back side rather than the front end edge of water stop plugs 7b and 7e, ie, the upper plate in the dead space of the upper part of water stop plugs 7b and 7e. The hardened portion 51 of the member 50 is disposed. This contributes to the miniaturization (space saving) of the entire faucet device 1.

  Further, the upper plate member 50 and the lower plate member 60 are provided with recesses 52 and 62, respectively, in order to effectively accommodate the temperature control function part 7g including a large-sized element member. Thereby, thickness reduction of the faucet apparatus 1 whole is achieved. In addition, the upper plate member 50 can be easily manufactured (formed) because the processing of the hardened portion 51 and the processing of the concave portion 52 do not interfere with each other due to the presence of the relief portion 53.

  Furthermore, the faucet device 1 (water discharge device) according to the present embodiment also exerts a force acting on the elbow flow passage 46e by fixing the elbow flow passage 46e to both the upper plate member 50 and the lower plate member 60. Can be well received.

  In addition, since the lower plate member 60 is provided with the cutaway portion 63 for allowing the water blocking valves 7b and 7e to penetrate, the degree of freedom in designing the arrangement positions of the water blocking plugs 7b and 7e and the flow paths 7c and 7f is improved. A thin faucet device 1 is realized without being hampered.

  In addition, since the cutaway portion 63 also penetrates the pipe 8 b (flow path for overhead) leading to the first overhead water discharge portion and the pipe 8 d (flow path for overhead) leading to the second overhead water discharge portion Even if a flow path is provided, the faucet device 1 is still thin.

  In addition, the push button mechanisms 10 a and 10 b (operation portion) and the water discharge ports 41 and 42 are disposed at positions not overlapping the cutouts 63 when viewed in the longitudinal direction of the lower plate member 60. , 10b (of the fixing member) can sufficiently receive the operation force, and the spouts 41, 42 can sufficiently receive a force such as a water hammer.

  Further, the lower plate member 60 has bent portions 65, 66 on both outer sides of the push button mechanisms 10a, 10b (operation portion) and the water discharge ports 41, 42 when viewed in the longitudinal direction of the lower plate member 60. Since the fixing members of the push button mechanisms 10a and 10b are fixed to the bent portions 65 and 66, (the fixing members of) the push button mechanisms 10a and 10b can receive the force at the time of operation more sufficiently. And the spouts 41, 42 can receive forces such as water hammer more sufficiently.

  Further, since the upper plate member 50 does not have a notch at a position overlapping the notch 63 of the lower plate member 60 in plan view, the strength of the lower plate member 60 is insufficient due to the presence of the notch 63. Where possible, the upper plate member 50 can be effectively reinforced.
