Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a hot and cold water mixing faucet with a structure in which the temperature of the discharged hot water and the flow of N can be adjusted at a separate location. It is something. (Prior art) Some recent faucet appliances automatically discharge water by simply extending a hand toward the spout, and then discharging water automatically after a predetermined period of time or by withdrawing the hand from the spout. There were so-called automatic faucets that automatically stopped discharging water. Furthermore, some automatic faucets of this type were capable of discharging not only water but also hot water.
Automatic faucets capable of discharging hot water needed to maintain the temperature of the discharged hot water within a predetermined range at all times, without being affected by changes in ambient temperature.
Conventionally, hot and cold water mixing faucets, which are commonly used in bathrooms, have been used as the temperature control mechanism for automatic faucets, except for those equipped with water heaters or hot water heaters that are located separately. Ta. Figure 5 shows a front cross-section of the most typical conventional hot water mixing faucet 1. The hot water mixing faucet 1 has a temperature adjustment handle 2.
, a temperature control unit 3, a hot water mixing chamber 4, and a flow rate adjustment handle 5 are arranged in a horizontal ring shape, and hot water is supplied from a hot water supply path 1b recessed in the inner peripheral surface of the faucet body 1a. The relative inflow of water and water from the water supply path 1c is adjusted by sliding the sliding valve body 8 driven by the temperature-sensitive elastic body 7, and is discharged when the temperature reaches a predetermined temperature in the hot water mixing chamber 4. It was designed to be sent to pipe 6. When this hot water mixing faucet 1 is used for the above-mentioned automatic faucet, the faucet main body 1
After removing the flow rate adjustment handle 5 and its valve part 5a from a, close that part and connect the flow path from the hot water mixing chamber 4 to the discharge pipe 6 to the solenoid valve or electric valve of the automatic faucet. I was doing it. FIG. 6 is a front view showing a situation in which an automatic water faucet IO is attached to the washbasin 9. The automatic faucet 10 is configured such that a temperature control system using the hot water mixing faucet 1 is arranged at the lower part of the washbasin B9, and only the discharge faucet 11 is attached to the upper surface of the washbasin 9. It had become. The hot and cold water mixing faucet l shown in the figure is one in which the temperature adjustment handle 2 is placed on the right end side of the faucet body 1a (the arrangement is reversed from that shown in Fig. 5). things) are shown. In addition, a solenoid valve or an electric valve is housed in a box 12 connected to the lower part of the faucet body 1a, and this valve receives a signal from a sensor 13 provided at the tip of the discharge faucet l1. It was designed to operate according to the signal. (Problem to be Solved by the Invention) As described above, the hot water mixing faucet l was designed to be attached to the lower part of the washbasin 9, but the lower part of the washbasin 9 was dimly lit. Since it is normal, the scale indicating the degree of rotation of the temperature adjustment handle 2 is difficult to see, making it difficult to check the degree of adjustment. In addition, when adjusting the set temperature in this way, it is necessary to operate the temperature adjustment handle 2 while bending down each time.
In addition, it was extremely troublesome to make fine adjustments to the temperature of the discharged hot water while measuring it by hand. The present invention has been made in view of the above circumstances, and it is possible to adjust the temperature and flow rate of hot water discharged even when the faucet body is attached to the lower part of a washbasin, for example. A new remote operation structure for hot and cold water mixing faucets that allows easy operation on the top side of the washbasin (hereinafter referred to as the "Structure")
The purpose is to provide the following. ``Inventive Precepts'' (Means for Solving the Problems) The gist of the structure is a faucet body with a built-in temperature control unit, a wash basin, and a counter. It consists of an adjustment handle attached to the upper surface of a wash basin or the like, and an operation cable that connects the faucet body and the adjustment handle. A sliding valve body that relatively adjusts the opening degree of the hot water supply path and the water supply path leading to the mixing chamber, and a sliding limiter that restricts the sliding area of the sliding valve body are provided, and the adjustment handle is provided with a sliding valve body that restricts the sliding area of the sliding valve body. A rotary power output end or a linear power output end connected to the rotary power output end via a motion converter is provided, and one end of the operating cable is connected to the output end of the adjustment handle, and the other end is connected to the output end of the adjustment handle. The main feature is that the faucet is connected directly or indirectly to a sliding limiter or a discharge amount regulating valve provided within the faucet body. (Function) In order to be able to adjust the temperature and flow rate of the hot water discharged from the top of the washbasin, the adjustment handle and the faucet body are separated and an operating cable is used to connect the two. It is set as. The operating cable transmits rotational or linear motion when the adjustment handle is operated to the faucet body, and the temperature is controlled in the faucet body by a mechanism similar to that of a conventional hot water mixing faucet. Adjustment or flow rate adjustment will now take place. (Example) The present invention will be described below based on drawings showing examples of the invention. FIG. 3 is a front view showing the attached state.

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. It is connected to the attached faucet main body 15 by an operating cable 17.
The operating cable 17 is a wire cable inserted into a flexible tube, and is connected to the faucet main body 1.
5, the operating force of the adjustment handle 16 can be transmitted to a temperature control unit (not shown) housed therein. Therefore, the user
You can adjust the temperature of the hot water while directly receiving it in your hands, and you can easily adjust the temperature in a very natural posture. In addition, in the figure, illustration of the supply pipe and wiring connecting the faucet main body 15 and the discharge tap body 1l is omitted. Next, the connection status of the operation cable 17 to the adjustment handle 16 will be explained. Figure 2 is a partially cutaway front view of the main part of the structure. The adjustment handle 16 is
A motion converter 18 is housed inside, and when the lever part 16a is rotated, a linear motion is transmitted at its output side. That is, the motion converter l
Reference numeral 8 indicates that a socket portion 20 that is externally screwed onto the rotation shaft 19 of the lever portion 16a is fitted into the inner circumferential surface of the housing 21 so as to remain unrotatable. I warn you. Therefore, when the lever part 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 2l, the rotation force does not allow linear sliding movement in the axial direction. The output will be changed. The input 6tAl7a of the operating cable 17 is connected and fixed to the socket portion 20 of the motion converter 18 at its lower end. Next, the connection status of the operation cable 17 to the faucet main body 15 will be explained. In addition, in the faucet main body 15,
The basic operating principle for mixing hot water and discharging hot water at an appropriate temperature is almost the same as that of the hot water mixing faucet 1 shown in FIG. The fact that the temperature control part 3 is housed, and that the flow rate adjustment handle and its valve part are not provided is almost the same as the conventional hot water mixing faucet l shown in FIG. However, in the faucet body l5 used in this example, the arrangement of the hot water supply passage 15b, the water supply passage 15c, the hot water mixing chamber 4, etc. recessed in the inner peripheral surface of the faucet body 15 is as shown in FIG. There are some differences from the hot water mixing faucet 1.

In FIG. 2, the temperature control unit 3 protrudes from the left end side of the temperature control unit 3 housed within the faucet body 15. things (indicated by code 7a)
is a piston portion of the temperature-sensitive expandable body 7.

The piston portion 7a has a stepped cylindrical sliding limiter 2.
2 is brought into contact with the operating cable 1.
The output end 17b of 7 is directly connected and fixed to this sliding limiter 22. Therefore, when the adjustment handle 16 is rotated as described above, the sliding limiter 22 moves to the faucet body 1.
5 will be operated in the entry and exit directions. The sliding limiter 2
2 will be briefly explained with respect to the conventional hot water mixing faucet 1 shown in FIG. In the conventional hot water mixing faucet 1, the sliding limiter 22 is fitted to the rotation shaft 23 of the temperature adjustment handle 2, and by rotating the temperature adjustment handle 2, the faucet can be opened. The degree of entry and exit from the main body 1a was adjusted. and,
The sliding limiter 22 is positioned within the faucet main body la to restrict the sliding area of the sliding valve body 8 attached to the temperature-sensitive expandable body 7. That is, by positioning the sliding limiter 22 toward the outside of the faucet body 1a to increase the sliding area of the sliding valve body 8, the opening degree of the water supply path 1c becomes larger than that of the hot water supply path 1b. As this condition continues for a long time, the temperature of the discharged hot water begins to drop. On the other hand, if the sliding limiter 22 is positioned closer to the inside of the faucet body 1a to reduce the sliding area of the sliding valve body 8, the temperature of the discharged hot water will rise. The effect of the sliding limiter 22 is the same in the faucet body 15 used in the present structure, and the temperature of the discharged hot water can be adjusted by operating the adjustment handle 16. (Study of Alternative Embodiments) In the above embodiment, the motion converter 18 is housed within the adjustment handle I6. However, the motion converter 18 may be housed within the faucet body 15. That is, in this case, operation cable 1
A motion converter 18 is interposed between the output end 17b of 7 and the sliding limiter 22, and the operation cable 17 is
The rotation of the adjustment handle 16 is directly transmitted to the faucet body 15 as a rotation. Further, the present structure can be implemented not only when adjusting the temperature of discharged hot water but also when adjusting the flow rate of discharged hot water. In this case, the rotation shaft 24 of the flow rate adjustment handle 5 shown in FIG. 5 may be replaced with the output end 17b of the operation cable 17, and the discharge amount adjustment valve 5a may be rotated by the output end 17b. Bye. FIG. 3 is a front view showing a situation in which the present structure is applied to a discharge stopper 26 attached to a wall-embedded washbasin 25. In this embodiment, the adjustment handle l6 is
It is attached to the upper surface of the sleeve portion 25a that bulges out toward the front side of the washbasin 25. Connect the operating cable I7 to the adjustment handle l6.
It is almost the same as the embodiment shown in FIG. It is. In addition, there is a type of hand wash basin other than the one shown in the figure, in which a skirt-like hanging part extends from the lower part of the sleeve part 25a to the front part of the sleeve part 25a. The faucet main body 15 and the like can be stored inside the hanging portion. This will give it a cleaner appearance. By the way, in order to start or stop the discharge of water or hot water from the discharge tap body 26, a human body detector 27 is embedded in the wall surface near the embedding position of the washbasin 25, and this is inserted into the faucet body 1.
It is designed to be electrically connected to a solenoid valve or an electric valve (not shown, but housed in box 12) connected to box 12. However, in the discharge plug body 11 shown in the embodiment of FIG.
was buried. Therefore, the discharge plug 1
It was very convenient to be able to control the discharge of water and hot water by simply inserting or withdrawing your hand directly below the l. Therefore, the discharge plug body 26 used in the hand wash basin 25 shown in FIG. 3 can also have a structure similar to that described above. FIG. 4 is a cross-sectional side view of a discharge plug 30 that is integrally equipped with a human body detector 29. The discharge plug 30
In this case, the discharge port 3l is covered with a flat oval case 32, and the human body detector 29 is housed inside the case 32. Reference numeral 33 in the figure is the central part of the human body detector 29 for transmitting and receiving signals. Furthermore, this structure is not limited to being implemented in automatic faucets, but also in bathrooms and kitchens. This can be applied to all types of hot and cold water mixing faucets used in washrooms, etc. In this way, the configuration and shape of the present structure can be changed as appropriate depending on the implementation mode. "Effects of the Invention" As is clear from the above explanation, according to the separate operation structure of the hot and cold water mixing faucet according to the present invention, it is possible to adjust the temperature and flow rate of discharged hot water, especially in the case of automatic faucets. Be able to do it easily and accurately. In addition, the mounting position of the faucet body is not subject to restrictions related to its operational convenience, so it can be used around the bathroom. Around the kitchen. The main body of the faucet can be hidden from view in areas such as washrooms, making it cleaner. Furthermore, since there is no need to attach a temperature adjustment handle, an operation converter, a flow rate adjustment handle, or its valve body to the faucet body, the structure is simplified and manufacturing is facilitated. It has many excellent advantages, such as lower manufacturing costs and improved appearance.
