Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a self-closing type mixing faucet that supplies mixed water having a desired temperature to a shower head and a discharge pipe side.

(Prior Art) FIG. 2 of Japanese Utility Model Publication No. 61-31229 (FIG. 4 of the present application) which is a conventional automatic valve closing type hot and cold water mixing faucet.
There is one. Briefly referring to FIG. 4 above,
The main body 50 of the self-closing type hot and cold water mixing valve has a branch chamber 51 for supplying the mixed water to either of two directions to a pipe joint 53 for supplying water to a shower head through a valve seat port 52 and the other side to a self-closing valve mechanism 52a. It is arranged so as to supply water to the discharge pipe 54 via the valve seat port, and to supply water to the discharge pipe 54, a predetermined flow rate is supplied by tilting the lever 55 downward, and to supply water to the shower head, the valve seat port is used. This is performed by pulling up the valve body 56 that closes the valve 52 by operating the screw feed of the handle 57.

In the case of the above, when the water is supplied to the shower head, the water does not pass through the self-closing valve mechanism, so that there is a disadvantage that the set amount of water cannot be supplied by operating one movement of the lever.

(Problems to be Solved by the Invention) A problem to be solved by the invention is that the mixed water supplied from the discharge pipe and the shower head can pass through the self-closing valve mechanism and the discharge water from both sides is discharged. The purpose is to be able to set different amounts of water.

(Technical Means for Solving Problems) The technical means taken by the present invention to solve the above problems are a hot water supply source, a hot water supply passage leading to the water supply source, and a water supply passage and a hot water mixing valve mechanism for communication. A branch plug chamber is provided, and a branch valve chamber leading to the shower head and a branch valve chamber leading to the discharge pipe are arranged above and below the branch plug portion to form a mixing plug body, and the branch valve chamber is self-closed. By mounting a valve mechanism and a self-closing valve unit consisting of a handle unit having a flow rate adjusting unit, the amount of water discharged from the shower head and the discharge pipe can be set to different flow rates.

(Function) To supply the mixed water to the shower head, press the upper handle to supply the mixed water waiting in the branch chamber. When the valve is closed, the valve is closed slowly due to the spring pressure and the fluid pressure. When the lower handle is operated in the same way to supply to the discharge pipe side, the mixed water in the branch chamber is supplied to the discharge pipe side and stopped slowly through the above procedure, and the discharge from the shower head and the discharge pipe is performed. The amount of water is set by the flow control unit of each self-closing valve unit.

22a has snap rings 34, 34a for preventing them from coming off from the insertion holes 25b, 25c to form handle units 36, 36a having the same structure, respectively.
The distance T between the inner end surface of the adjusting screw 27 of the handle unit 36 and the facing end surface of the bush 33 is set to a distance different from the same distance T ′ of the handle unit 36a, so that the flow rate supplied from the shower head can be adjusted. It can be adjusted to be different from the flow rate supplied from the discharge pipe 10.
Further, when the pressure of the mixed water supplied from the shower head is high, the flow rate of the valve seat port 9b arranged in the middle of the mixed water flow path 37 of the self-closing valve mechanism 19 can be adjusted by the adjusting valve body 38. It is arranged.

The branch plug portion 6 has an annular valve body 40, which controls the flow rate of the hot water valve seat 39 of the hot water supply chamber 4 and the water valve seat 39a of the water supply chamber 5, on one side. A movable case 42, which is in communication with the temperature sensitive medium 41, is provided inside, and the temperature sensitive medium 41 has at one end a working end 43 that senses the hot water temperature and expands and contracts, and has a connector 44 and a spring of the fixed case 42a. 1
7d is connected to a valve rod 45 for opening and closing the valve, and by operating the handle 20b attached to the valve rod 45 in the valve closing direction, the spring 17d, the connector 44, and the working end 43 are connected.
In the order of arrow P, the movable case 42 together with the temperature-sensitive medium 41 and the annular valve body 40 linked to the movable case 42 are displaced in the same direction to close the hot water valve seat 39. When the handle 20b is operated in the valve opening direction, each of them operates in the reverse direction of the arrow P in the opposite direction to open the hot water valve seat 39 to supply hot water, and the hot water communicates with the hot water valve seat 39. While passing through the case 42 and flowing out from the outlet 46 to the branch chamber 7, the temperature sensitive medium 41 senses the temperature of the hot water and the sensitive action thereof extends the working end 43, and the action thereof causes a sense. Heating medium 41
At the same time, the movable case 42 and the annular valve body 40 linked to the movable case 42 are displaced in the same direction, and the opening amount of the hot water valve seat 39 is reduced by this operation, while the water valve seat 39a is slightly moved. An appropriate amount of cold water is introduced into the movable case 42 from an inlet 47 which is opened and communicates with the water valve seat 39a, and the inside of the movable case 42 is mixed with hot water flowing to obtain an appropriate temperature from the outlet 46 to the branch chamber 7. A hot and cold water mixing valve mechanism c for supplying the mixed water of

Now, a case will be described in which the handle 20b shown in FIGS. 2 and 3 is preliminarily operated, and then the appropriate temperature of the mixed water is supplied to the discharge pipe 10 side. First, the handle 20a is operated in the pressing direction. Along with this, the operating shaft 22a moves in the same direction, and the valve body 11a standing by in the moving direction.
Since the driven shaft 14a is pressed, the valve body 11a integral with the driven shaft 14a is displaced in the same direction against the accumulated force of the spring 17a to open the valve seat opening 9a. In this case, the handle 20a is released from the pressing force when the inner end of the adjusting screw 27a feels the collision with the bush 33a.
The valve body 11a tries to return to the fixed position by the elastic return of the spring 17a. The hot water introduced from the gap between the hot water valve seat 39 and the annular valve body 40 by opening the valve seat opening 9a first wash the peripheral surface of the temperature sensitive medium 41 shown in FIG. It flows to 7. During this time, the temperature sensitive medium 41 sensitive to the hot water is activated to extend the working end 43, and the extending operation causes the temperature sensitive medium 41 to move.
Since it is displaced in the direction of arrow P together with 2, the gap between the hot water valve seat 39 and the annular valve body 40 is reduced by the amount of displacement, and at the same time, the gap between the water valve seat 39a and the annular valve body 40 is opened to allow cold water to enter the inlet 4
7 is introduced into the movable case 42. By introducing this cold water, the hot water passing through the movable case 42 is lowered to an appropriate temperature and flows out to the branch chamber 7 through the outlet 46 and reaches the discharge pipe 10 from the branch chamber 7 through the valve seat port 9a shown in FIG. It is released to the outside as it is. In the meantime, the valve body 11a receives the elastic pressure due to the elastic return of the spring 17a to rapidly return to the valve closing direction so that the pressure of the fluid passing through the valve seat opening 9a brakes. Since the valve body 11a gradually returns to the valve closed position in order to operate, the water is stopped after supplying a predetermined amount of the mixed water set by the preliminary flow rate adjusting unit B1. Next, when the handle 20 is operated in the above-described manner to make a shower bath and the valve body 11 is pressed to open the valve seat opening 9, the mixed water is mixed with the valve seat opening 9 and the valve seat of the mixed water flow path 37. It is supplied to the shower head through the mouth 9b. In this case, the flow rate is set such that the distance T between the inner end surface of the adjusting screw 27 and the end surface of the bush 33 is the handle unit 3 described above.
Since the distance T'is larger than the interval T'of 6a, the discharge amount per discharge is large due to the larger distance. Therefore, the delay time for the valve seat opening 9 to return to the closed state becomes long, and during this time, the dirt and soap adhered to the body can be sufficiently washed out, and when a predetermined amount is released, the water is stopped, so that other body Apply soap to the part,
Since dust can be rubbed, the mixed water is not wasted by stopping the water during this period. Further, the adjustment of the flow rate adjusting parts B, B1 is performed by screwing back the small screws 29, 29a and adjusting the adjusting screws 27, 27a by adjusting the adjusting screws 27, 27a from the outside of the handles 20, 20a and the caps 32, 32a with a screw driver. When finished, the machine screws 29, 29a may be tightened.

(Effects) The present invention has the following advantages because of the above-described configuration.

(1) Since the branch valve chamber leading to the shower head of the mixer tap body and the branch valve chamber leading to the discharge pipe are equipped with a self-closing valve mechanism and a self-closing valve unit consisting of a handle unit equipped with a flow rate control unit, It is possible to discharge water at a set flow rate from the head and the discharge pipe, and to discharge different set amounts of water from the discharge pipe or the shower head as needed.

(2) Since the self-closing valve units installed in both branch valve chambers are both equipped with a flow rate control unit, the amount of water discharged from the shower head and the discharge pipe can be set arbitrarily with different flow rates according to the application, The mixed water can be economically used without being discharged.
