Reference numeral 27 denotes a protective body that covers the cover body 20 except for the base part b of the discharge pipe 2. This protector 27
Is composed of a cylindrical body 29 and a holding piece 30 that sandwich the periphery of the discharge pipe rear end b. That is, in the lower part of the cylindrical body 29, a vertical portion 28 b, 28 b having an inverted U-shape in side view and capable of sandwiching the discharge pipe 2 from the left and right and having a width interval L is provided, and a round portion capable of sandwiching the discharge pipe 2 from above. 28a
Is formed. The vertical portion 28
b, 28b function as guide rails, and the recesses 30a, 30a formed at both ends of the holding piece 30 are engaged with the vertical portions 28b, 28b, so that the holding piece 30
Are guided in the notches 28.

Further, the protective body 27 includes a protective pipe 2.
4 is provided with a locking means B. That is, the locking means B serves to prevent the protection pipe 24 from turning when the protection pipe 24 is inserted into the discharge pipe 2 through the insertion hole 24a. 24, a plurality of projections 3 provided on the rear end face m.
1 and a recess 32 in which the protrusion 31 is fitted.

In this embodiment, both the outer shape of the vertical section of the discharge pipe 2 and the water outlet 23 of the discharge pipe 2 are circular, and the protection pipe 2
The insertion hole 24a of No. 4 is circular, and the outer shape of the protection pipe 24 in a vertical section is elliptical. The insertion hole 26a of the cap 26 into the discharge pipe tip 2a is circular, and the outer shape of the vertical cross section of the cap 26 is elliptical.

The cap 26 is provided at the bottom portion n and the discharge pipe tip 2a with a stopper / seal means C for preventing the cap 26 from being detached from the discharge pipe tip 2a and for sealingly attaching the cap 26 to the discharge pipe tip 2a. This retaining / sealing means C
Is a stepped hole 40 formed in the bottom n of the cap 26.
The water screw in the insertion hole 26a is prevented from leaking from the hole 40 by contacting the wood screw 41 screwed into the hole 40 and the neck portion 41a of the wood screw 41 while being fitted in the step portion 40a of the hole 40. Ring-shaped sealing member 4
2 and a hole 43 provided at the discharge pipe distal end 2a where the distal end portion 41b of the wood screw 41 is located.

Further, a sealing means D is provided at the tip 2a of the discharge pipe.
Is provided. The sealing means D includes a ring-shaped groove 45 provided near the hole 43 and a sealing member 46 fitted in the groove 45.

After covering the cover body 20 with the protection body 27, the protection pipe 24 is formed on the discharge pipe 2 by the projection 31.
2 and then insert the insertion hole 26a of the cap 26 into the exposed end portion 2a of the discharge pipe and attach the wood screw 41 and the seal member 42, so that the protection pipe 24 and the cap 26 are attached. At the same time, the cover body 20 and the discharge pipe 2 are completely covered with the protection body 27, the protection pipe 24, and the cap 26. In this embodiment, a resin molded product is used as the protection body 27, the protection pipe 24, and the cap 26.

Thus, the cover 20 and the discharge pipe 2 can be covered with a simple operation.

Further, since the cover body 20 and the discharge pipe 2 can be completely covered, it is not necessary to perform expensive buffing and plating on the cover body 20 and the discharge pipe 2, and the cost can be reduced accordingly.

Further, the cover 20 and the discharge pipe 2 are
7. Since the product is transported while being covered with the protective pipe 24 and the cap 26, even if the surface of the protective body 27, the protective pipe 24 and the cap 26 is damaged, the protective body 27 can be mass-produced at low cost. It is only necessary to replace the pipe 24 and the cap 26.

Moreover, in this embodiment, the cover 20
Then, the discharge tube 2 becomes hot and the user can be reliably prevented from directly touching and getting burned.

FIG. 5 shows two discharge pipes 2 and 2 communicating with an annular flow path 22 (see FIG. 1), while a protective pipe 24 is provided.
And the cap have a corresponding number of discharge tube insertion holes 24a, 2
4 shows a second embodiment of the present invention provided with 4a.

In this case, since two discharge pipes 2 and 2 are provided, the strength for supporting the protection pipe 24 and the cap 26 can be improved as compared with the case of one discharge pipe, and the discharge pipes 2 and 2 are frequently connected. You can hardly break even if you move left and right.

In each of the above embodiments, the protection body 27,
Although a resin molded product is used as the protection pipe 24 and the cap 26, a metal molded product may be used in the present invention. In this case, the protection body 27, the protection pipe 24, and the cap 26 can be mass-produced, and there is an advantage that no harmful components are mixed in the hot and cold water as compared with a resin molded product.

[0030]

As described above, according to the present invention, the cover and the discharge pipe can be covered with a simple operation.

Further, since the cover body and the discharge pipe can be completely covered, it is not necessary to perform expensive buffing and plating on the cover body and the discharge pipe, and the cost can be reduced accordingly.

Further, since the product is transported in a state where the cover body and the discharge pipe are covered with the protective body, the protective pipe and the cap, even if the surface of the protective body, the protective pipe and the cap is damaged, a large amount can be produced at low cost. It only requires changing the protective body, protective pipes and caps that can be produced, and solves product management problems.

Moreover, when a resin molded product is used as the protective body, the protective pipe and the cap, for example, the cover body and the discharge pipe become hot, and it is possible to reliably prevent the user from directly touching and burning. In addition, as a protective body, a protective pipe, and a cap, for example, when a metal molded product is used,
It has the advantage that no harmful components are mixed in the water.
