(Action effect)
In the faucet device 1 (water discharge device) according to the present embodiment as described above, when the 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 path 46e. The elbow flow path 46e tends to be displaced in the vertical direction. However, in the faucet device 1 according to the present embodiment, the upper plate member 50 arranged on the upper side of the elbow flow path 46e has a hardened portion 51 composed of bent portions 51a and 51b, so that the elbow flow path 46e Can fully accept the force acting on.

Further, since the cured portion 51 of the present embodiment is arranged on the rear side of the elbow flow path 46e, the degree of freedom in designing the arrangement positions of the spouts 41 and 42 is not hindered. Therefore, there is no problem in handling the shower hose 43.

Further, since the hardened portion 51 of the present embodiment is formed along the longitudinal direction of the upper plate member 50, the strength of the upper plate member 50 can be effectively increased.

Further, the cured portion 51 of the present embodiment is composed of a first bent portion 51a that bends downward from the horizontal direction and a second bent portion 51b that bends so as to return from the first bent portion 51a in the horizontal direction. However, these bends can be produced by bending. That is, the effect of work hardening by the bending process can be obtained. Further, since the first bent portion 51a is bent downward, it is avoided that the thickness of the entire faucet device 1 becomes thick.

Then, as shown in FIG. 16, the hardened portion 51 is located on the rear side of the front end edge of the water stopcocks 7b and 7e, that is, the upper plate is placed in the dead space above the water stopcocks 7b and 7e. The hardened portion 51 of the member 50 is arranged. 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 store 7 g of the temperature control function portion including a large element member. As a result, the thickness of the entire faucet device 1 is reduced. Further, since the processing of the cured portion 51 and the processing of the recess 52 do not interfere with each other due to the presence of the relief portion 53, the upper plate member 50 can be easily manufactured (molded).

Further, in the faucet device 1 (water discharge device) according to the present embodiment, the force acting on the elbow flow path 46e is also caused by the elbow flow path 46e being fixed to both the upper plate member 50 and the lower plate member 60. Can be fully accepted.

Further, since the lower plate member 60 is provided with a notch 63 for penetrating the water stopcocks 7b and 7e, the degree of freedom in designing the arrangement positions of the water stopcocks 7b and 7e and the flow paths 7c and 7f is increased. A thin faucet device 1 is realized without being hindered.

Further, since the cutout portion 63 also penetrates the pipe 8b (overhead flow path) leading to the first overhead water discharge portion and the pipe 8d (overhead flow path) leading to the second overhead water discharge portion, these overhead passages are used. Even if the flow path is provided, the faucet device 1 is still thin.

Further, since the push button mechanisms 10a and 10b (operation units) and the water discharge ports 41 and 42 are arranged at positions that do not overlap with the notch 63 when viewed in the longitudinal direction of the lower plate member 60, the push button mechanism 10a The 10b (fixing member) can sufficiently receive the force at the time of operation, and the spouts 41 and 42 can sufficiently receive the force like a water hammer.

Further, the lower plate member 60 has bent portions 65 and 66 on both outer sides of the push button mechanisms 10a and 10b (operation portions) and the spouts 41 and 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 push button mechanisms 10a and 10b (fixing members) can receive the force at the time of operation even more sufficiently. , The spouts 41 and 42 can more and more sufficiently receive the force like a water hammer.

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 a plan view, the strength of the lower plate member 60 becomes insufficient due to the presence of the notch 63. The strength can be effectively reinforced by the upper plate member 50 at the obtained portion.
