(Problems to be Solved by the Invention) As described above, the hot and cold water mixing faucet 1 was designed to be attached to the lower portion of the washbasin 9, but the lower portion of the washbasin 9 is dim. Since it is normal, it is difficult to see the scale indicating the degree of rotation of the temperature control handle 2, and it is difficult to confirm the degree of control. In addition, when adjusting the set temperature in this way, the temperature adjustment handle 2 must be operated with a posture of bending down.
In addition to that, fine adjustment while manually measuring the temperature of the discharged hot water was extremely troublesome.

The present invention has been made in view of the above circumstances, and even when the faucet body is attached to a lower portion of a washbasin, for example, the temperature control and the flow rate control of the hot water discharged can be performed. A new separation operation structure for hot and cold water mixing faucet that can be easily performed on the top side of the washbasin (hereinafter referred to as the structure of this case)
The purpose is to provide.

[Structure of the Invention] (Means for Solving the Problems) The gist of the structure of the present invention is that it is attached to the faucet body with a built-in temperature control unit and to the upper surface of an appropriate place such as a washbasin, counter, and handwasher. The temperature control part in the faucet body is composed of a control handle and an operation cable connected between the faucet body and the control handle. A sliding valve body that relatively adjusts the opening of the passage and a sliding limiter that regulates a sliding area of the sliding valve body are provided, and the adjustment handle has a rotary motion output end or the rotary motion output end. Is provided with a linear motion output end connected via a motion converter, one end of the operation cable is connected to the output end of the adjustment handle, and the other end is provided with a sliding limit provided in the faucet body. For body or discharge control valve In that is adapted to be indirectly or indirectly connected.

(Function) In order to adjust the temperature and flow rate of the discharged hot water on the upper surface of a proper place such as a washbasin, separate the adjustment handle from the faucet body and connect the both with an operation cable. There is. With the operation cable, the rotational movement or the linear movement when the adjustment handle is operated is transmitted to the faucet body as it is. In the faucet body, the temperature is controlled by the same mechanism as the conventional hot and cold water mixing faucet. Adjustment or flow rate adjustment is performed.

(Example) The following will describe the present invention with reference to the drawings illustrating an example thereof.

FIG. 1 is a front view showing a state in which the automatic faucet 14 having the present structure is attached to the washbasin 9. As is clear from the figure, in the present structure, an adjustment handle 16 is attached to the upper surface of the washbasin 9 so as to be adjacent to the discharge plug 11, and the adjustment handle 16 is attached to the lower part of the washbasin 9. An operation cable 17 is connected to the attached faucet body 15. The operation cable 17 is formed by inserting a wire cable into a flexible tube, and with respect to the faucet body 15, to the temperature control section (not shown) housed therein, The operating force of the adjusting handle 16 can be transmitted.
Therefore, the user can adjust the temperature while directly receiving the hot water discharged from the discharge plug body 11, and the adjustment operation can be easily performed in an extremely natural posture. . In the figure, the faucet body 15
The supply pipe and the wiring connecting the discharge plug 11 and the discharge plug 11 are not shown.

Next, the connection status of the operation cable 17 to the adjustment handle 16 will be described. FIG. 2 is a front view showing a partial cutout of the main part of the present structure. The movement handle 18 is housed inside the adjustment handle 16, and when the lever portion 16a is rotated, a linear movement is transmitted on the output side thereof. That is, the motion converter 18 has a lever portion.
Socket part 2 that is screwed onto the rotating shaft 19 of 16a
0 is fitted to the inner peripheral surface of the housing 21 so as to maintain a non-rotatable state. Therefore, when the lever portion 16a is rotated, the socket portion 20 also tries to rotate together with the rotation shaft 19, but since the socket portion 20 is prevented from rotating by the housing 21, the rotation power is increased. Will be output by changing the operation to linear sliding in the axial direction. Then, in the socket portion 20 of the motion converter 18,
The input end 17a of the operation cable 17 is connected and fixed to the lower end side of the.

Next, the connection status of the operation cable 17 to the faucet body 15 will be described. The basic operating principle of the faucet body 15 for discharging hot water by mixing hot water is substantially the same as that of the hot and cold water mixing faucet 1 shown in FIG. Regarding the fact that the temperature control unit 3 is housed inside the faucet body 15 and the flow control handle and its valve unit are not provided, the conventional hot and cold water mixing faucet 1 shown in FIG. Is almost the same as. However, in the faucet body 15 used in the present embodiment, the arrangement of the hot water supply passage 15b, the water supply passage 15c, the hot and cold water mixing chamber 4, etc., which are recessed in the inner peripheral surface, is shown in FIG. It has some differences from the hot and cold water mixing faucet 1.

In FIG. 2, what protrudes to the left end side of the temperature control section 3 housed in the faucet body 15 (indicated by reference numeral 7 a) is the piston section of the temperature-sensitive expandable body 7. The piston portion 7a includes
A stepped cylindrical slide limiting body 22 is brought into contact with the slide limiting body 22, and the output end 17b of the operation cable 17 is directly connected and fixed to the slide limiting body 22. Therefore, when the adjusting handle 16 is rotated as described above, the slide limiting body 22 slides in the faucet body 15 in the direction of insertion and removal. The operation of the sliding restrictor 22 will be briefly described with reference to the conventional hot and cold water mixing faucet 1 shown in FIG. In the conventional hot and cold water mixing faucet 1, the sliding restrictor 22 is adapted to be screwed onto the rotating shaft 23 of the temperature adjusting handle 2, and by rotating the temperature adjusting handle 2, the faucet The degree of access to the main body 1a was adjusted. The sliding restrictor 22 is positioned within the faucet body 1a to regulate the sliding area of the sliding valve body 8 attached to the temperature-sensitive stretchable body 7. That is, if the sliding restrictor 22 is positioned outside the faucet body 1a to increase the sliding area of the sliding valve body 8, the opening degree of the water supply passage 1c becomes larger than that of the hot water supply passage 1b. Since the state continues for a long time, the temperature of the discharged hot water is lowered. On the contrary, if the sliding restrictor 22 is positioned inward of the faucet body 1a and the sliding area of the sliding valve body 8 is reduced, the temperature of the discharged hot water rises. The action of the sliding restrictor 22 is similar to that of the faucet body 15 used in the structure of the present invention, and consequently, the temperature of the discharged hot water can be adjusted by operating the adjusting handle 16.

(Consideration of Another Mode) In the above embodiment, the motion converter is provided in the adjusting handle 16.
Shown is the one that 18 can now be stowed. However, the motion converter 18 may be housed in the faucet body 15. That is, in this case, the output end of the operation cable 17
The motion converter 18 is interposed between the slide limiter 17b and the sliding limiter 22, and the operation cable 17 transmits the rotation of the adjustment handle 16 to the faucet body 15 as a rotational movement as it is. Further, the present structure can be implemented not only when adjusting the temperature of the discharged hot water but also when adjusting the flow rate of the discharged hot water. In this case, the rotating shaft 24 of the flow rate adjusting handle 5 shown in FIG. 5 is replaced with the output end 17b of the operation cable 17, and the output end 17b is used to rotate the discharge amount adjusting valve 5a. Good.

FIG. 3 is a front view showing a situation in which the structure of the present case is applied to the discharge plug 26 attached to the wall-embedded hand washing device 25. In the present embodiment, the adjusting handle 16 is a hand washing device.
It is attached to the upper surface of the sleeve portion 25a that bulges to the front side of 25. The operation cable 17 is connected to the adjustment handle 16, and the other end of the operation cable 17 is connected to the faucet body 15 arranged at the bottom of the handwasher 25. It is substantially similar to the embodiment shown. In addition to the illustrated hand washing device, there is a type in which a skirt-shaped hanging portion extends from the lower part of the sleeve portion 25a to the front surface thereof, but in this type of hand washing device, The faucet body 15 and the like can be housed inside the hanging portion. By doing so, the appearance becomes neat.

By the way, when starting or stopping the discharge of water or hot water in the discharge plug body 26, the human body detector 27 is embedded in the wall surface near the embedded position of the hand washing device 25, and this is connected to the faucet body 15. Solenoid valve or motorized valve (not shown, box 12
It is stored inside) and is electrically connected. However, in the discharge plug body 11 shown in the embodiment of FIG. 1, the human body detector 28 is embedded on the tip side of the discharge port. Therefore, it is very convenient because the discharge condition of water or hot water can be controlled only by inserting or retracting the hand directly below the discharge plug 11. Therefore, the discharge plug 26 used in the hand washing device 25 as shown in FIG. 3 can have the same structure as the above. Figure 4 shows the human body detector
FIG. 3 is a side sectional view showing a discharge plug body 30 integrally including 29. The discharge plug 30 has a discharge port portion 31 covered with a flat egg-shaped case 32, and the human body detector 29 is housed inside the case 32. Reference numeral 33 in the figure denotes a central portion of transmission and reception in the human body detector 29.

Further, the structure of the present invention is not limited to being applied to an automatic faucet, but can be applied to all hot and cold water mixing faucets used in bathrooms, kitchens, washrooms and the like. As described above, the configuration and shape of the present structure can be appropriately changed according to the embodiment.

[Effects of the Invention] As is clear from the above description, according to the separating operation structure of the hot and cold water mixing faucet according to the present invention, particularly in the case of an automatic faucet or the like, temperature control and flow rate control of discharged hot water can be performed. You can do it easily and accurately. In addition, since the installation position of the faucet body is not restricted by the convenience of its operation, the faucet body can be made invisible around the bathroom, kitchen, washroom, etc. Clean Further, in the faucet body, since it is not necessary to attach a temperature control handle, a motion converter, a flow rate control handle or its valve body, the structure is simplified, the manufacturing is facilitated, the manufacturing cost is reduced, It has many excellent advantages such as improvement in appearance.
