[0013]
Reference numeral 5 denotes a temperature control unit that can be connected to the temperature control handle 3, and is inserted into the faucet body 1 through the opening 1b so as to be coaxial with the axis A of the faucet body 1.
[0014]
The temperature control unit 5 has a cylindrical case 40, and the inner end 5 a of the case 40 is configured to be connectable to the inner end 4 a of the case 15 of the switching unit 4 via the O-ring 6. . In this embodiment, the inner end 5a is detachably fitted into the inner end 4a. A thermo element (not shown) containing thermo wax is fixedly installed inside the case 40 of the temperature control unit 5. And case 40 has the single hot water intake hole 40a located in the trunk | drum directly downstream of the hot water connection port 8 so that it may communicate with the hot water connection port 8. In FIG. 4, H denotes a hot water supply side passage from the hot water connection port 8 to the hot water intake hole 40 a formed in the case 40. On the other hand, a plurality of water intake holes 40 b communicating with the water connection port 10 are formed around the body portion of the case 40. The plurality of water intake holes 40 b communicate with the water connection port 10 via a substantially annular channel formed between the faucet body 1 and both cases 40 and 15. In FIG. 4, R indicates a water supply side passage that extends from the water connection port 10 to the plurality of water intake holes 40 b formed in the case 40 through the substantially annular flow path.
[0015]
Then, the hot water in the hot water supply side passage H and the water in the water supply side passage R are mixed in the case 40, and as shown in FIG. 4, a mixed flow path i is formed and the connection portion between the inner end 5a and the inner end 4a. The inner space S (see FIG. 2) formed by the rotation member 50 (described later) of the valve mechanism 99 built in the case 15 passes through the inside.
[0016]
The valve mechanism 99 is switched by the switching handle 2 and supplies water, hot water, or mixed water from the inner space S to the water discharge pipe connection port 14, the shower hose connection port 12, or the third connection port 60. And has the function of stopping supply.
[0017]
Reference numeral 16 denotes a communication hole provided on the back side of the body portion of the case 15 of the switching unit 4, which communicates with the shower hose connection port 12. 16 a is a communication hole provided on the lower surface side of the body portion of the case 15 of the switching unit 4 and communicates with the water discharge pipe connection port 14.

The communication hole 16 and the communication hole 16b are provided in the body portion with a central angle of 90 °.
[0018]
Although not shown, the temperature control unit 5 includes a thermo element and a piston. When the thermo element senses the temperature of the mixed water, the thermo wax expands to push out the piston and change the position of the thermo valve body. As a result, the clearance of the hot water intake hole 40a (the clearance of the hot water supply side passage H passing through the case 40) and the clearance of the water intake hole 40b (the clearance of the water supply side passage R passing through the case 40) are adjusted. The temperature of the mixed water can be arbitrarily set by the temperature control handle 3.
[0019]
The automatic temperature control operation of the temperature control unit 5 is as follows.
When the temperature control handle 3 is rotated around the axis A of the faucet body 1 and set to a predetermined temperature, the mixed water having a predetermined temperature passing through the mixing channel i is connected to the water discharge pipe 63 and the shower head 65. It flows to the hose 69 connected to the shower hose 64 or the watering device 66.
[0020]
When the temperature of the mixed water rises above a predetermined temperature, the thermo element senses the temperature and the thermo wax in the thermo element expands to move the thermo element to the temperature control handle 3 side. While narrowing the hot water supply side passage H into the case 40, the water supply side passage R into the case 40 is widened. Thereby, the temperature of mixed water falls and it can adjust to predetermined temperature. On the other hand, when the temperature of the mixed water falls below a predetermined temperature, the thermo element senses the temperature, and the thermo wax in the thermo element contracts to move the thermo element to the switching handle 2 side, so that the thermo valve body is the case 40. While expanding the hot water supply side passage H, the water supply side passage R into the case 40 is narrowed. Thereby, the temperature of mixed water rises and it can adjust to predetermined temperature.

[0023]
Hereinafter, the valve mechanism 99 will be described.
[0024]
The valve mechanism 99 is built in the case 15 of the switching unit 4. The valve mechanism 99 rotates around the axis A of the faucet body 1 to flow water, hot water, or mixed water from the hot water mixing chamber S to the water discharge pipe connection port 14, the shower hose connection port 12, or the third.

In FIG. 3, F denotes the communication holes 16, 16 a. The area | region between the position of the end side of 16b and the end surface position of the said inner side edge part 4a is shown. That is, the region F indicates a region between the position of the cutout hole 57 of the rotating member 50 and the end surface position of the inner end portion 4a in the case 15.
[0025]
Further, the fixing member 51 is fixed to the inner peripheral surface side of the case 15 with holes 53, 53a, 53b communicating with the communication holes 16, 16a, 16b provided in the case 15, respectively.
[0026]
The cutout hole 57 communicates with the communication holes 16, 16 a, and 16 b through the holes 53, 53 a, and 53 b by the switching operation of the switching handle 2. FIG. 2 shows a state in which the notch hole 57 communicates with the shower hose connection port 12 through the hole 53 and the communication hole 16, while FIG. 2 shows the mixing flow path in the inner space S. It is shown that i becomes the flow path T ₁ from the shower hose connection port 12 to the shower hose 64 via the valve mechanism 99. Further, in FIG. 4, the mixing flow path i of the inner space S becomes a flow path T ₂ from the water discharge pipe connection port 14 through the water discharge pipe joint 13 to the water discharge pipe 63 via the valve mechanism 99. It is shown. Further, in FIG. 4, the mixing flow path i of the inner space S is a flow path T from the third connection port 60 through the joints 70 and 74 (described later) to the watering device 66 via the valve mechanism 99. It is shown to be ₃ .
[0027]
Next, a connection mechanism for connecting the water supply hose 69 connected to the watering device 66 to the third connection port 60 will be described.
[0028]
Reference numeral 70 denotes a joint having a simple attachment / detachment mechanism, which is attached to the third connection port 60 by screw connection. The joint 70 has a cylindrical case 71 having a spindle 73 as an on-off valve body biased upward in the axial direction by a spring 72 and an annular valve seat 80 provided at an inlet 71 a of the case 71. That is, the third connection port 60 is always closed by the spindle 73 coming into contact with the valve seat 80 by the urging force of the spring 72. Even if the switching handle 2 is switched, the third connection port 60 is mistakenly changed. Even if the connection ports 60 communicate with each other, a water stoppage state can be secured. A cap 84 is configured to be opened and closed by a hinge 84 a provided on the upper surface side of the faucet body 1 and has a function of covering the joint 70. The cap 84 is in an open state with its lower opening L directed obliquely upward. The joint 70 has an external thread m formed at the lower part of the case 71, while the third connection port 60 has an internal thread n at the upper part to be screwed with the external thread m.
[0029]
Reference numeral 74 denotes a joint provided at the upstream end of the water supply hose 69 connected to the watering device 66, and the joint 74 is detachably attached to the joint 70. In this embodiment, the joint 74 is provided with an internal thread that is screwed into an external thread 81 formed on the surface on the inlet side of the case 71. That is, the joint 74 has a pressing body (not shown) for separating the spindle 73 from the valve seat 80 at a position corresponding to the spindle 73. Then, from the state shown in FIG. 2, after opening the cap 84, the joint 73 is screwed into the joint 70 to move the spindle 73 downward in the axial direction against the urging force of the spring 72. The joint 74 has a pressing body for separating the spindle 73.
[0030]
Thus, when washing the bathroom B with hot water, the watering nozzle 66 having a jet watering pattern can be easily connected to the faucet body 1. Then, by simply switching the switching handle 2 to the third connection port 60 side and setting the temperature control handle 3 to a predetermined temperature, the mixed water can be ejected from the watering nozzle 66 almost straightly and vigorously.
[0031]
Further, when the shower head 65 connected to the shower hose 64 does not have, for example, a massage shower spray pattern, the shower hose with the joint 74 connected to the shower head with the massage shower is detachable from the joint 70. The massage shower can be performed without replacing the shower head 65 simply by attaching to the shower head.
[0032]
In this way, since the watering device such as the watering nozzle 66 and the showerhead with a massage shower can be easily attached to the faucet body 1 in addition to the showerhead 65 and the water discharge pipe 63, the purpose of using hot water in the bathroom B Can be widened.
[0033]
5 and 6 show that the water, hot water, or mixed water is supplied to and stopped from the third connection port 60 regardless of the switching operation of the switching handle 2. 2nd Embodiment is shown. 5 and 6, the same reference numerals as those shown in FIGS. 1 to 4 are the same or equivalent. The second embodiment will be described below with reference to FIG. 3 used in the description of the first embodiment.
[0034]
The case 15 has a communication hole 16 and a communication hole 16a on the back surface and the bottom surface, respectively, as in the first embodiment, while communicating with the third connection port 60 as shown by a two-dot chain line in FIG. A hole 16d is provided in the region F. That is, in the first embodiment, the communication holes 16b communicating with the third connection port 60 and the communication holes 16 and 16a are arranged in a row, but in the second embodiment, the case is connected to the case from the communication holes 16b. A communication hole 16 d that communicates with the third connection port 60 is formed at the upper surface position displaced toward the inner end 4 a side of 15. Therefore, the fixing member 51 has only the holes 53 and 53a communicating with the communication holes 16 and 16a, respectively, so that the mixing channel i does not communicate with the communication hole 16d from the inner space S of the rotating member 50. The fixing member 51 is formed with a partition wall portion 51d.
[0035]
And the hot water of the hot water supply side passage H and the water of the water supply side passage R are mixed in the case 40, and as shown in FIG. 6, it becomes a mixing flow path i and is connected to the inner end portion 5a and the inner end portion 4a. When passing through the interior space S formed by the rotating member 50 of the valve mechanism 99 built in the case 15, the mixing flow path i of the inner space S is connected to the shower hose via the valve mechanism 99. The flow path T ₁ extends from the connection port 12 to the shower hose 64, or the mixing flow channel i of the inner space S passes through the water discharge pipe joint 13 from the water discharge pipe connection port 14 via the valve mechanism 99. The flow path T ₂ reaches 63.
[0036]
On the other hand, the hot water in the hot water supply side passage H and the water in the water supply side passage R are mixed in the case 40 and pass through the connecting portion between the inner end portion 5a of the case 40 and the inner end portion 4a of the case 15, and the communication hole. The mixing flow path i ′ that has passed through 16 d communicates with the third connection port 60. The flow path T ₃ in FIG. 6 is a flow path in which the mixing flow path i ′ not passing through the valve mechanism 99 but passing through the communication hole 16d passes from the third connection port 60 through the joints 70 and 74 to the watering device 66. Indicates.
[0037]
In each of the above embodiments, the water supply hose 69 connected to the watering device 66 is connected to the third connection port 60. However, the present invention also includes other water supply hoses different from the water supply hose 69. Available.
[0038]
For example, a water supply hose connected to a mist sprayer used when a bathroom is used as a sauna can be connected to the third connection port 60. In other words, the mist sprayer for spraying mist is placed in a bathroom washing place, but conventionally, hot water is supplied from a water discharge pipe of a thermo-type hot and cold water mixing faucet installed in the bathroom to supply water to the mist sprayer. In contrast to the introduction to the mist sprayer through the hose, in the first embodiment of the present invention, the switching handle 2 is switched to the third connection port 60 side, so that the third discharge port 63 is not used. Hot water can be introduced into the mist sprayer from the connection port 60.
[0039]
In the second embodiment of the present invention, hot water is supplied from the third connection port 60 to the mist sprayer while discharging water, hot water, or mixed water from the water discharge pipe 63 or the shower head 65. Can be introduced.
[0040]
Furthermore, it goes without saying that the present invention can be applied to a case where a valve body made of a ceramic disk is used in place of the valve mechanism 99.
[0041]
【The invention's effect】
As described above, in the present invention, an existing shower head can be used so that a shower with a different watering pattern can be used without replacing an existing shower head in the bathroom, and the bathroom can be washed with a spray nozzle. It is possible to provide a thermo-type hot and cold water mixing faucet that can be used immediately for watering devices having different purposes, and that can also use other watering hoses different from the watering hoses connected to the watering devices.
