Abstract

PURPOSE:To improve the controllability of a faucet, by unturnably arranging a display plate, which shows the position of displacement of a valve body to be pointed, in the turning center of a rotary handle. CONSTITUTION:A faucet rod 13 is provided longitudinally movable in the axial direction further unturnably in wafer flow casing 12, and a rotary handle 25 is screwed to a threaded shaft part 27 of said faucet rod 13, then a display plate 30, which shows a turning position of said rotary handle 25 to be pointed, is mounted to the outside of the faucet rod 13 by a machine screw 31. In this way, the display plate 30, being consequently arranged unturnably in the turning center of the rotary handle 25 to display the displacement of a valve body, can easily confirm the position of the displacement of the valve body through a turning position of the handle 25 for the display plate 30, and the controllability of a faucet is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to make the displacement position of the valve body of a water faucet clear by displaying the rotational position of the handle, thereby increasing its operability by several times.

Bathroom mixer faucets are generally configured so that by rotating the handle, the output of hot water can be switched from the faucet side to the shower side or from the shower side to the faucet side. Is it in a state?
Alternatively, it may be difficult for people who are not used to using conventional hot and cold mixer faucets to understand whether the water is on the shower side or when the hot water faucet is turned on, the hot water intended to be discharged from the faucet may be discharged from the shower side. There was a difficult side to it.

The present invention has been made in view of the above, and by non-rotatably disposing a display plate indicating the displacement position of the valve body at the rotation center of the rotary handle, the displacement position of the valve body can be determined from the rotation position of the rotary handle. The aim is to make it easier to check and diagnose water faucets, and to improve the ease of use of the water faucet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A flow path switching section of a mixing faucet showing an embodiment of the present invention will be described below.

In Figure 1, Figure 1, the piping that connects to the hot water source,!
is the hot water tap, 3 is the hot water handle, 4 is the pipe that connects to the water supply source, 5 is the water tap, 6 is the water supply handle, and γ is the hot water tap! A hot water mixing pipe connects the secondary side of the water supply faucet 2 with the secondary side of the faucet 2, 8 is a faucet that is rotatably attached with a bag neck (9), and 10 is a shower connection that is connected to a shower water spout (not shown). The port 11 indicates a cap nut to which the shower connection port 10 is attached.

A stopper rod rib is provided in the flowing water casing ν formed at an intermediate position of the hot water mixing pipe 7 so that it can move forward and backward in the axial direction but cannot rotate. That is, a water sealing O-ring 15 is interposed in the opening 14 provided on the front side of the running water housing, and the guide tube 16 is loaded into the running water housing branch, and the valve seat part 17 at the tip of the guide s16 is placed in hot water. It faces into the mixing pipe 7 and faces the valve seat part connected to the shower connection port 10. A water sealing O-ring 19 fitted on the outer periphery of the guide tube 16 near the tip is brought into close contact with the inner periphery of the running water sieve. A conical valve body formed by covering the outer end of the stopper rod 13 with rubber is located inside the hot water mixing pipe 7. The water seal O-ring 4 fitted around the outer periphery of the stopper rod 13 is slidably in close contact with the inner peripheral surface of the guide tube 16. Reference numeral 22 denotes a guide bottle screwed onto the side wall of the guide cylinder 16, and the protruding end of the guide bottle inside the guide cylinder 16 is connected to the plug rod 1.
It loosely fits into a guide groove bored along the axial direction on one side of 3. A communication legend provided on the side wall of the guide tube 16 allows communication between the inside of the guide tube and the inside of the faucet 8.

The passage is a rotary handle in which a threaded part is rotatably fitted into the front protrusion of the guide cylinder 16, and the threaded part is screwed into the threaded shaft part 27 of the stopper rod rib. A locking pin is engaged with nine rows of seven runs formed on the forward protruding end of the guide tube 16 to prevent the rotary handle 5 from coming off.

(Main) is a disc-shaped display plate, which is fixed to the outer end of the stopper rod 13 with a screw and placed in a fitting hole recessed in the center of rotation of the 5-turn handle 5. On the surface P, a mark representing a shower and a mark representing discharge from a faucet are displayed in the upper and lower positions, respectively, and an arrow path is displayed on the surface of the rotating handle portion. The arrow part is now the first
As shown in the figure, when the mark M is pointing, the stopcock rod is in the retracted position as shown in Figure 1, and the valve body is attached to the valve seat 1.
8, the water in the hot water mixing pipe 7 enters the guide tube 16 exclusively through the valve seat 17 which is in an open state, and is discharged directly through the faucet. Therefore, by rotating the rotary handle 1, the rotational motion of the rotary handle is converted into a forward and backward movement of the stopper rod 13 by the threaded engagement between the screw cylinder part holder and the screw shaft part I, and the stopper rod is advanced. The body is moved away from the valve seat part and moved further forward to bring it into close contact with the valve seat part 17, and is switched to the shower connection port 10 side of the hot water mixing pipe 7 where water is flowing.

At this time, since the guide pin η is loosely fitted into the guide groove for the stopper rod, the stopper rod moves forward and backward without turning m1. Therefore, even if the rotating handle 5 is rotated, the display plate located at the center of rotation will not rotate, and the arrow part of the rotating handle will point to the mark on the display plate. become.

The embodiment shown in Figure 1 is constructed so that the movement of the stopper rod is not transmitted to the display plate I, but the same parts or equivalent parts as in the previous embodiment will be given the same reference numerals. A detailed explanation will be omitted, and only the different parts will be explained. A spline shaft y is formed at the outer end of the stopper rod, and the spline shaft W is loosely fitted into the spline hole 38 bored at the center of the back of the display plate (material). Vertical grooves are formed on the inner circumferential surface of the spline shaft to match a large number of spline-shaped longitudinal grooves on the outer circumference of the spline shaft, so that both splines are fitted together.Thereby, the stopper rod 13 can move forward and backward between the two splines. Therefore, even if the rotating handle 5 is twisted to move the stopper bar forward or backward, the display plate (material) will not only rotate but also move forward and backward. do not.

Although the above embodiments are related to the flow path switching section of a hot water mixing faucet, the handle position display device of the present invention can be applied not only to such a flow path switching section, but also to the opening/closing section of running water, the water volume adjustment section, or It can be widely applied to display the operation position of the rotary handle of each part of the water faucet, such as the hot water mixture ratio adjustment part, and FIG. 5 shows an example of the display plate and handle for water volume adjustment.

In short, according to the present invention, since the display plate that non-rotatably displays the displacement of the valve body is disposed at the center of rotation of the rotary handle, the displacement position of the valve body can be easily confirmed by the rotational position of the handle with respect to the display plate. This has the effect of improving the operability of the water faucet and making it easier to use.
