Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a mixed faucet capable of switching the fluid in the mixing chamber to a discharge chamber and a shower chamber by moving a switching valve arranged in the mixing chamber of the faucet body. Regarding

(Prior Art) Conventionally, there is a mixing faucet shown in FIG. 3 as a mixing faucet capable of switching a fluid in a mixing chamber to a discharge chamber side and a shower chamber side by operating a switching valve.

Briefly referring to FIG. 3, the main body 40 of the mixing faucet has an internal mixing chamber 41 provided with a switching valve 42 which can be moved forward and backward by operating a handle 43.
4 is rotatably mounted by a mounting pipe 45 and a blind nut 45a, and when the switching valve 42 is seated on the shower valve seat 46, the fluid in the mixing chamber 41 flows from the discharge pipe 44 through the water discharge chamber 47. When the switching valve 42 is supplied and the switching valve 42 is seated on the discharge valve seat 48, the fluid is supplied to the shower head through the elbow 51 and the shower hose which are screwed into the opening 50 communicating with the shower valve port 49. Is supplied to.

Since the above-mentioned mixing faucet has a function to switch to the shower side, it is necessary to form an opening for mounting the elbow, which makes it impossible to make the main body compact and imposes restrictions on the design, and When assembling the faucet, the step of attaching the elbow is added, which causes a problem that productivity is deteriorated.

(Problems to be solved by the invention) The problems to be solved by the invention are to make the shape of the mixing faucet having a flow path switching function between the water discharge chamber and the shower chamber compact and reduce the number of parts. The purpose is to facilitate the assembly.

(Technical Means for Solving Problems) The technical means taken by the present invention to solve the above problems is to provide a fluid passage to a water discharge chamber and a shower chamber in a mixing chamber of a main body by operating a handle. In a mixed water faucet that has a switching valve for switching and a discharge pipe is attached to the bottom of the main body, the mounting pipe that rotatably supports the discharge pipe on the main body has both ends open and a shower channel inside. And a connecting portion for connecting a shower hose and a flange for press-contacting a step portion of the discharge pipe via an O-ring at the other end. is there.

(Function) When the switching valve closes the shower valve, the fluid in the mixing chamber is supplied from the discharge pipe through the water discharge valve and the water discharge chamber, and when the handle is operated in the valve opening direction, the switching valve opens the water discharge valve. And the fluid in the mixing chamber reaches the shower channel of the mounting pipe for supporting the discharge pipe on the main body through the shower valve port and the shower chamber, and supplies it to the shower hose connected to this mounting pipe.

(Embodiment) An embodiment of the present invention will be described below in detail with reference to the drawings.

In the embodiment of the present invention, as shown in FIG. 1, the main body 1 of the mixing faucet has a fitting portion 2 projecting in an annular shape at a lower portion thereof, and an annular receiving seat 3 is formed on an outer periphery of the fitting portion 2. There is. The discharge pipe 4 penetrates near the mouth end on a vertical line to open an upper insertion hole 5 and a lower insertion hole 6 having a diameter smaller than that of the upper insertion hole 5.
And an annular groove 7 for fitting an O-ring on the outer periphery of the lower insertion hole 6,
7a are formed respectively. The cylindrical mounting tube 8 has both ends open and has a shower channel 9 through which a fluid passes, and one end of the cylindrical mounting tube 8 is connected to a screw port 22a provided in a shower chamber 22 of the main body 1, which will be described later. An annular groove 7b for fitting an O-ring is formed, and at the other end, a connecting portion 1 for connecting a shower hose (not shown) leading to a shower head.
1 and an annular flange 12 are formed.

The attachment tube 8 may be a combination of two articles.

The discharge pipe 4 is fitted into the fitting portion 2 of the main body 1 after the O-ring 13 and the washer 14 are fitted into the annular groove 7 of the upper insertion hole 5, and the O-ring 13a is fitted to the upper portion of the annular groove 7b and the flange 12, respectively. , 8b into which the mounting tube 8 is inserted
Is inserted from the lower insertion hole 6 of the discharge pipe 4, the screwing portion 10 is coupled to the screw opening 22a of the shower chamber 22, and the flange 12 is pressed against the step portion 15 of the discharge pipe 4 via the O-ring 13b. As a result, it is rotatably attached to the main body 1.

The main body 1 is provided with an opening 17 in a mixing chamber 16 provided with a mixing valve A for mixing hot water and water therein, and a valve cylinder 18 is fitted into the opening 17 and the valve cylinder 18 has a water discharge chamber. A water discharge valve port 20 communicating with 19 is formed, and the attachment pipe 8 is provided on a partition wall 21 of the main body 1.
A shower valve port 23 communicating with the shower channel 9 and the shower chamber 22 is formed, and the both valve ports 20 and 23 are arranged at positions opposite to each other, and the water discharge chamber is provided between the both valve ports 20 and 23. A switching valve 24 for switching a flow path to the valve 19 or the shower chamber 22 is interposed, and the switching valve 24 is connected to a handle 26 via a spindle 25 screwed into the valve cylinder 18 and is movably supported.

Now, when the flow rate adjusting handle (not shown) of the mixed faucet is operated in the valve opening direction, the shower valve port 23 is closed by the switching valve 24 as shown in FIG. 1 and FIG. The fluid in the mixing chamber 16 reaches the discharge pipe 4 through the water discharge valve port 20 and the water discharge chamber 19, and is supplied to the outside from the water discharge port 27 of the discharge pipe 4. Next, when it is desired to switch the fluid supply to the shower side, when the handle 26 is operated in the valve opening direction, the switching valve 24 linked to the spindle 25 rises and the discharge valve port 20 is opened as shown in FIG. While closing and opening the shower valve port 23, the fluid in the mixing chamber 16 is supplied through the shower chamber 22 from the shower channel 9 of the mounting pipe 8 to the shower hose connected to the connecting portion 11.

(Effect) Since the present invention is configured as described above, it has the following advantages.

(1) A mounting pipe that rotatably supports the discharge pipe on the main body has both ends opened to form a shower channel inside, and a screwing portion that is coupled to a screw mouth of the shower chamber is provided at one end, and the other end is provided. Since the flange for pressing the step portion of the discharge pipe through the O-ring and the connecting portion for connecting the shower hose are provided, the connecting portion for connecting the discharge pipe to the main body and attaching the shower hose with a single connecting pipe. Can be installed at the same time, and the cost of the assembly can be reduced by reducing the number of parts compared to the conventional method of connecting the discharge pipe and installing the elbow for connecting the shower hose with another article. Can be shortened and productivity can be significantly improved.

(2) Since it is not necessary to provide an opening for mounting the elbow to connect the shower hose to the main body of the mixed faucet, the degree of freedom in design is greatly expanded and the mixed faucet can be made extremely compact, and the bath It can be installed without being restricted by the installation position when it is installed in a room.
