g, 7g are inserted into fitting holes 6m, 6m formed in the rear end of the main body heat insulating cover 6.

Thereafter, the main body heat-insulating cover 6 and the main body heat-insulating plate are connected to the hot water supply pipe 21 and the water supply pipe 22 previously attached to the wall surface of the bathroom, etc., via the adapters 23, 23 comprising the joint nut 23a and the tightening nut 23b. The mixer tap main body 1 to which 7 and the like are attached is attached. Thus, the hot water supply pipe 21 and the water supply pipe 22
Is connected. The hot water pipe 21 has the hot water pipe 2
1 to cover the hot water supply pipe heat insulating cover 24 having heat insulating properties.
Is attached. The hot water supply pipe heat insulating cover 24 includes one half of the half body 24a and the other half of the half body 24b, and is attached so as to sandwich the hot water pipe 21 from both sides. Further, on one half body 24a of the hot water supply pipe heat insulating cover 24, projections 24c, 24c are formed at positions facing the other half half body 24b, and the other half of the hot water supply pipe heat insulating cover 24 is provided. The projections 24c, 24c are provided on the split body 24b at positions facing the one half half 24a.
Are formed so as to be fitted by press-fitting. Further, when the hot water pipe heat insulating cover 24 is attached to the hot water pipe 21, the outer peripheral surfaces 21 b and 21 c of the hot water pipe 21 on the inflow side and the outflow side of the hot water and the hot water pipe 21 on the side of the flow rate regulating water shutoff valve unit 21 a, respectively. , 21d
The outer peripheral surfaces 21b and 21 of the hot water pipe heat insulating cover 24
inner peripheral surfaces 24e and 24 corresponding to c and 21d, respectively.
f, 24g fit tightly. Thus, the hot-water supply pipe heat insulating cover 24 is attached to the hot-water supply pipe 21 without play.

A water supply pipe heat insulating cover 25 having the same structure as the hot water pipe heat insulating cover 24 and having heat insulating properties is also attached to the water supply pipe 22. That is, the water pipe insulation cover 25 is

6b, at a position facing one of the half bodies 26a,
A fitting hole 26d into which the projection is fitted by press-fitting;
26d are formed.

The hot water supply pipe heat insulating cover 24, the water supply pipe heat insulating cover 25 and the discharge pipe heat insulating cover 26 are made of, for example, ABS, similarly to the main heat insulating cover 6 and the main heat insulating plate 7.
Although it is made of a synthetic resin material such as resin, in order to unify the appearance, the same heat insulating cover 6, the main body heat insulating plate 7, the hot water supply pipe heat insulating cover 24, the water supply pipe heat insulating cover 25, and the discharge pipe heat insulating cover 26 are used. It is desirable to choose a material.

Next, the operation and effect of the mixing tap having the above-described structure will be described. In this hot / water mixer tap, the heat insulating cover of the main body is 6, and the mixer tap main body 1 has an upper surface 1k, a front surface 1m, a lower surface 1n, one side surface 1e and the other side surface 1h.
From the front of the mixer tap main body 1 so as to cover the Then, the temperature control bonnet 9 and the mixing valve presser 1
0 is inserted so as to fit into the first mounting hole 6h on one side 6d and the second mounting hole 6i on the other side 6e of the heat insulating cover 6 of the main body. And the second
Are detachably attached to the mixing plug main body 1 so as to cover the through holes 1f and 1i. Thus, the main body heat insulating cover 6
The fitting to the temperature control bonnet 9 and the mixing valve retainer 10 attached to the mixing tap main body 1 prevents the mixing tapping main body 1 from coming off and is fixed. Therefore, the temperature control bonnet 9 and the mixing valve retainer 10 ensure that
The main body heat insulating cover 6 can be fixed to the mixer tap main body 1. In addition, the temperature control bonnet 9 is
Since e is compressed and fitted into the first mounting hole 6h of the main body heat insulating cover 6, the main body heat insulating cover 6 can be fixed to the mixer tap main body 1 without play. The main body heat insulating cover 6 allows the user to heat the mixing plug main body 1.
Can be prevented from directly touching the upper surface 1k, the front surface 1m, the lower surface 1n, and both side surfaces 1e, 1h. Further, when the temperature adjusting bonnet 9 and the mixing valve retainer 10 are removed, the first and second through holes 1 penetrating into the mixing plug main body 1 are removed.
f and 1i appear, and the maintenance of the mixing tap main body 1 becomes easy. In addition, the temperature adjusting bonnet 9 functions not only as a fixing member for attaching and fixing the main body heat insulating cover 6 to the mixer tap main body 1 but also as an attaching member for attaching the temperature control handle 5. Further, since the main body heat insulating cover 6 is made of a synthetic resin that is easy to print, the temperature display 6j, which is a display for indicating the temperature of the mixed water, can be easily and clearly printed on the surface of the main body heat insulating cover 6.

Further, the main body heat insulating plate 7 covering the rear surface 1p of the mixer tap main body 1 can prevent a user from directly touching the rear surface 1p of the heated mixer tap main body 1.
Since the main body heat insulating plate 7 is directly screwed to the mixer tap main body 1, it is firmly fixed to the mixer tap main body 1. Further, the hot water supply pipe heat insulating cover 24 that covers the hot water supply pipe 21 and the discharge pipe heat insulating cover 26 that covers the discharge pipe 2 can prevent the user from directly touching the hot water supply pipe 21 and the hot discharge pipe 2. Furthermore, the water supply pipe insulation cover 25 covering the water supply pipe 22 allows the user to cool the cold water supply pipe 22.
Can be prevented from touching directly. The hot water supply pipe heat insulating cover 24, the water supply pipe heat insulating cover 25, and the discharge pipe heat insulating cover 26 are assembled into two parts by fitting the projections and the fitting holes, so that the removal is easy. Since it can be performed, maintenance of the hot water supply pipe 21, the water supply pipe 22, and the discharge pipe 2 is easy.

Further, as shown in this embodiment, the metal parts of the mixing tap (mixing tap main body 1, temperature control bonnet 9, mixing valve retainer 10, hot water supply pipe 21, water supply pipe 22, discharge pipe 2, etc.) If most of the resin is covered with a synthetic resin material, it can be used as a mixer tap installed in a modern bathroom or wash basin where the synthetic resin material is frequently used, so that the material can be unified and the appearance is excellent.

Note that the present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the water / water mixer tap according to the present invention may be applied not only to a thermostatic water / water mixer tap, but also to a two-handle water / water mixer tap or a single lever type water / water mixer tap.
Also, since the lower surface 1n of the mixer tap main body 1 is originally difficult for a user to touch, the lower portion 6c of the main body heat insulating cover 6 may not be provided.
Further, even if the outer peripheral surface of the flange portion 10b of the mixing valve retainer 10 does not fit with the second mounting hole 6i of the main body heat insulating cover 6, the cap 14 fits with the second mounting hole 6i. Is also good. In this case, the mixing valve presser 10 and the cap 14
Both functions as a fixing member for fixing the main body heat insulating cover 6 to the mixer tap main body 1. Also, the main body heat insulating cover 6, the main body heat insulating plate 7, the hot water supply pipe heat insulating cover 2
4. Water supply pipe insulation cover 25 and discharge pipe insulation cover 26
Is not limited to a synthetic resin material as long as it has a heat insulating property.
