Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting mechanism for a hot and cold water mixing faucet. 2. Description of the Related Art FIG. 4 shows an example of a conventional mounting mechanism for installing a hot and cold water mixing tap on a wall surface. In FIG. 4, hot water supply / water supply pipes (not shown) are provided in a state where pipe removal fittings 71, 71 are embedded in hot water supply / water supply outlets a, b formed on a tiled wall 72, for example. , And each extraction fitting 71, 71 and a hot-water mixing tap 73.
A hot and cold water mixing tap 73 is arranged via adapters 76 and 77 mounted between the eccentric pipes 74 and 75.
One end of each of the adapters 76 and 77 has an eccentric tube 7.
4, 75, which are inserted into water holes K provided in
On the other hand, the other end is screwed to the take-out fittings 71, 71 by sealing the threads 81, 82 with seal tape S together with the washers 79, 80 fixedly arranged on the adapters 76, 77. Is done. In addition,
83 is a faucet. However, the hot and cold water mixing tap 7
In the case of 3, unlike a single faucet, a hot and cold mixing faucet 7
It is necessary to separately attach the pipe 3 to the outlet a and the outlet b separately, which increases the number of work steps and labor. [0004] In addition, a large number of joint parts such as extraction fittings 71 and 71, adapters 76 and 77, and connecting parts necessary for mounting the eccentric tubes 74 and 75 are required. In addition, the cost increases. Further, since the hot and cold water mixing tap 73 is installed between the wall 72 and the eccentric tubes 74 and 75, the length of the outlet is increased by that amount, and there is a problem in downsizing. Moreover, the hot / water mixer tap 3 is taken out and the metal fittings 71, 7 are taken out.
When detaching from the bracket 1, it is necessary to release the screw from the metal fittings 71, 71, so that there is a problem that workability is not easy depending on a special environment or an installation place. In addition, the sealing tape S must be used to prevent leakage, which is troublesome and increases costs. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to easily and easily attach a hot and cold water mixing tap body to each of hot and cold water supply pipes and to reduce the number of components.

Open and close the water passage 10 of the
1 normally biases the lever 4 side. Reference numeral 12 denotes a partition wall for partitioning the hot water chamber 6 and the water chamber 7, and one end thereof also serves as a valve seat 13 of the regulating valve 8. The other end of the partition wall 12 is located at the center of the hot water inlet 14 and functions as a receiving base 16 of a first fitting member 15 described later. The hot water inlet 14 is formed on the rear surface side of the central part opposite to the lever 3 so as to protrude from the rear wall 1a, and the partition wall 12 is located at the center. Next, the components on the pipe joint 19 side including the hot water supply pipes 17 and 18 attached to the hot and cold water mixing tap main body 1 will be described. Reference numeral 19 denotes a pipe joint installed in a wall hole 21 formed in the surface of the wall 20, and a hot water outlet path 24 and a hot water outlet path 24 by a second insertion member 23, which will be described later, which is inserted into an oval hot / water outlet 31 in a front view. A water extraction channel 26 is formed.
The hot water inlet 22 is connected to the hot water supply pipe 17 by, for example, screwing using a cap nut 27.
Reference numeral 5 is connected to the water supply pipe 18 by screwing using a cap nut 28. On the other hand, the hot water discharge path 24 and the water discharge path 26
Is formed by a pair of tubular adapters 29 and 30 constituting the second fitting member 23. This tubular adapter 2
Reference numerals 9 and 30 are made of a material having a heat insulating function. The tubular adapter 29 comprises a tubular portion 29a and a flange portion 29b. Similarly, the tubular adapter 30 comprises a tubular portion 30a and a flange portion 30b. The notches formed in the flange portions 29b, 30b are fitted from the outlet 31 as the contact surfaces A. 32, 32 are O-rings. In addition, the partition wall 5 is located inside the outlet 31.
0 is formed, and portions of the tubular adapters 29 and 30 excluding the contact surface A are partitioned by the partition wall 50 and positioned. Next, the first fitting member 15 will be described. Similar to the tubular adapters 29 and 30, the first fitting member 15 is made of a material having a heat insulating function, and is connected to the hot water introduction path M communicating with the hot water chamber 6 and to the water chamber 7. The water introduction paths N communicating with each other are provided side by side. Finally, a connection mechanism between the pipe joint 19 and the hot and cold water mixing tap main body 1 will be described. Hot water outlet 3 of fitting 19
A screw 34 is formed on the outer periphery of the joint portion 33 forming the screw 1, and a screw 36 is also formed on the outer periphery of the inlet portion 35 forming the water inlet 14 of the mixer tap body 1.
Then, the pipe fitting 19 in which the tubular adapters 29 and 30 are fitted is installed in the wall hole 21, and the first fitting member 15 is fitted in the hot / water mixer tap main body 1 with the first fitting member 15 fitted. Flange portions 29b, 30 of tubular adapters 29, 30
b, and the cap nut 38 serving as a connecting member is screwed into the screw 3.
By screwing to the hot water supply pipes 4 and 36, the hot and cold water mixing tap main body 1 can be attached to each of the hot water supply and water supply pipes 17 and 18.
Reference numeral 40 denotes a support for the pipe joint 19, which is screwed to a mounting portion 41 formed on the pipe joint 19 so as to be supported by the support 40.
Fixed on top. Reference numeral 42 denotes a metal ring stopper for fixing the pipe joint 19 to the wall hole 21 via the annular surface 19a of the pipe joint 19. In the above embodiment, the cylindrical adapters 29 and 30 fitted into the outlet 31 are provided with the notch forming the contact surface A and the partition wall 5 formed in the outlet 31.
0 prevents rotation, so that the pipe joint 19
The hot water discharge path 24 and the water discharge path 26 can be reliably positioned. Therefore, by screwing the cap nut 38 onto the screws 34, 36, the hot water discharge path 24 and the hot water introduction path M can be reliably communicated, and at the same time, the water discharge path 26 and the water introduction path N can also be reliably connected. Further, since the first and second fitting members 15 and 23 are formed of a material having a heat insulating function, it is possible to prevent the water temperature from rising due to the hot water temperature and also prevent the pressure from expanding. As described above, according to the present invention,
Hot water supply and water supply outlets by connecting hot water supply, water supply piping and hot water mixer tap body to one fitting fixed to the wall hole,
Hot and cold water mixing valve body of the hot water chamber, hot water into the water chamber and a water inlet channel were formed, respectively, hot water the hot and cold water mixing valve body, so attached to the water supply the pipes, the effect shown below. 1. With one pipe joint, hot water can be supplied from hot water supply and water supply pipes and taken out to the hot water mixing tap main body, so that the number of work steps can be reduced, and the labor for installation can be saved. 2. The eccentric tube conventionally used can be eliminated, and the number of connection parts required for mounting can be reduced. Also, the cost is reduced. 3. Since the eccentric tube is not required, the protruding portion can be reduced and the size can be reduced, and the mounting space accompanying the size reduction can be reduced. [0019] In addition, according to the present invention, the hot and cold water mixing valve body of the hot water
Since the first fitting member is fitted into the water inlet and the second fitting member is fitted into the hot water outlet of the pipe joint, if the first and second fitting members are formed of a material having a heat insulating function, leakage is prevented. In addition to this, there is an advantage that the water temperature can be prevented from rising due to the hot water temperature and the pressure can be prevented from expanding.
