Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a faucet device for mixing hot water and a water-only machine, and more specifically, it describes mixed water and water (hereinafter, for convenience, a faucet device for mixing hot water and water). The present invention relates to an improved technique of a faucet device in which mixed water is spouted by selectively switching between a shower device and a straight water spouting device.

[Conventional technology]

As one of such typical conventional faucet devices, two spouts are provided in the hot and cold water mixing chamber of the faucet body, and a shower device and a straight water spout are connected to each of these spouts. In some cases, a flow path switching valve for switching and supplying mixed water to these is provided close to the hot water mixing chamber and between the mixing chamber and the water discharge port.

[Problems to be solved by the invention] Such a faucet device is used, for example, in a sink or a bathroom of a kitchen, but it requires an expensive flow path switching valve having a complicated structure, which is costly. It had the drawback of being expensive.

Further, after the shower is used, it is essential to operate the switching valve to switch the mixed water to the water discharge form from the water discharger, but it is easy to forget this flow path switching operation. , Next time when using the faucet device,
There is an inconvenience that the mixed water is discharged from the shower device in an unexpected direction.

Furthermore, since this switching valve is close to the hot and cold water mixing chamber and is interposed between the hot and cold water mixing chamber and the spout, after the shower is used, it goes to, for example, the sink where the hot and cold water mixing chamber exists, or if it is in the bathroom. It was a cumbersome task because I had to bend over and switch.

An object of the present invention is to provide a faucet device that simplifies the flow path switching structure and does not require the trouble of switching the flow path after using the shower.

[Means for Solving the Problems]

The faucet device of the present invention is provided with one inflow port at one end,
A first flow path that communicates from the inflow port to the first outflow port and a second outflow port that connects the first outflow port and the second outflow port independently to each other at the other end. A second flow path communicating with the outflow port is formed, and the respective total lengths of the first flow path and the second flow path are made independent of each other, and the respective cross-sectional areas thereof are the inflow port and the first and second outflow ports. The opening of the second flow path is formed on the side of the first flow path formed in the first flow outlet in the radial direction of the opening of the first flow path, and the inlet of the flow path switching member is formed. Is connected to the water outlet of the faucet body, a shower device is connected to the first outlet, and a straight water discharger is connected to the second outlet, and the shower device is manually operated to be normally closed. A type of on-off valve is provided.

[Action]

In the faucet device of the present invention, when the opening / closing valve of the faucet body is opened,
Although water flows out from the water outlet through the inflow port of the flow path switching member to the first outflow port, the cross-sectional area of the first flow path is smaller than the cross-sectional area of the inflow port. Therefore, the flow of water flowing from the water discharge port to the inflow port is somewhat blocked by the first flow path having a small cross-sectional area, and the water is slightly retained in the inflow port. Higher pressure. Therefore, the water flowing from the inflow port through the first flow path is jetted at high pressure to the first outflow port.

Since the opening / closing valve provided in the shower device is a normally closed type, the water ejected at high pressure from the first flow path to the first outlet cannot flow toward the shower device. The water is ejected from the water discharger through the second flow passage formed on the side of the first flow passage to the second outlet.

When the opening / closing valve of the shower device is opened in the above state, the first
The high-pressure water jetted from the flow path to the first outlet flows at high speed toward the shower device due to the jet pressure. Therefore, an air flow is generated at the first outlet along with the water flow that is jetted from the first flow passage and moves at a high speed, and this air flow causes the air in the second flow passage to be absorbed and flow in the first outlet. . Therefore,
An air flow is generated in which the second flow passage becomes a negative pressure and the air at the second outlet flows out through the second flow passage to the first outlet, and the second flow passage is disconnected compared to the second outlet. Since the area is small, the pressure of the air flow ejected from the second flow path to the first outlet is high.

That is, when the opening / closing valve of the shower device is opened, the water ejected from the first flow path flows toward the shower device at a high speed, and the pressure increases in the second flow path opening to the side of the first flow path. Generated air flow, and the flow directions of the water flow and the air flow are the same. Therefore, part of the high-pressure water ejected from the first flow path does not flow out from the first flow outlet toward the second flow outlet against the air flow generated in the second flow path, and the first flow path is prevented. Almost all the water spouted from the shower spouts from the shower device. When the opening / closing valve of the shower device is closed, as described above, the flow of water ejected from the first flow path to the first flow outlet is switched to the second flow outlet via the second flow path.

〔Example〕

An embodiment of the faucet device of the present invention will be described below with reference to the hot and cold water mixing tap shown in FIGS.

In FIGS. 1 and 2, reference numeral 1 in the drawings is a hot water supply valve section with a built-in hot water supply opening / closing valve, 2 is a water supply valve section with a built-in hot water supply opening / closing valve, which are provided on both sides of a communication pipe 3 forming a hot and cold water mixing chamber, In addition, a water spout body 4 is formed by connecting a water discharge port 4 to an intermediate portion of the communication pipe 3.

Reference numeral 5 is a flow path switching member connected to the water discharge port 4.

As shown in FIG. 3, the flow path switching member 5 includes a lateral T-shaped main body 8 having one inflow port 6 and two first and second outflow ports 7a and 7b. 6 to the first outflow port 7a, an L-shaped first flow channel 9, and two L-shaped second flow channels 10a and 10b from the first outflow port 7a to the second outflow port 7b.
Is formed and configured. The cross-sectional areas of the first flow passage 9 and the second flow passages 10a, 10b are considerably smaller than the cross-sectional areas of the flow inlet 6 and the first and second flow outlets 7a, 7b, and the first flow outlet 7a The respective openings of the second flow paths 10a and 10b are arranged side by side on both sides of the opening of the first flow path 9 in the radial direction. The flow path cutting member 5 is connected to the discharge port 4 of the faucet body A at the inflow port 6.

Reference numeral 12 is a shower device in which a shower body 13 is connected to the tip of the hose 11, and the first inlet port of the flow path switching member 5 is provided.
It is connected to 7a.

As shown in FIGS. 4 and 5, a shower fitting 14 having a large number of small holes is provided on the tip side of the shower body 13, and the shower fitting 13 is provided inside the shower body 13 in correspondence with the fitting 14. A valve seat 15 is provided.

16 is a water supply pipe connected to the tip side of the hose 11,
It is slidably provided in the shower body 13. Reference numeral 17 denotes a spring 17 that urges the tip of the water supply pipe 16 against the valve seat 15 to close the pipe flow path.

The water supply pipe communicating with the valve seat 15 and the hose 11.
A so-called normally-closed type on-off valve that constantly closes the shower channel is configured mainly by the spring 17 that urges and abuts the tip of the water supply pipe 16 against the valve seat 15.

18 is an operation tool for sliding the water supply pipe 16,
Operation member that is locked to the projection 22 that is continuous with the water supply pipe 16
21 are connected in series and are pivotally attached to the shower main body 13 via pins 20. Reference numeral 19 is a fitting hole for the operation tool 18.

Reference numeral 23 is a rotatable straight water spouting device connected to the second outlet 7b of the flow path switching member 5, 24 is a hot water supply on / off valve operation handle, 25 is a water supply on / off valve operation handle, and 26 is a hot water supply pipe. , 27 are water supply pipes.

As described above, in this faucet device, the shower device 12 and the water discharger 23, which are connected to the first and second outlets 7a and 7b of the flow path switching member 5, are the second flow path of the flow path switching member 5. Roads 10a, 10b
It is configured to always communicate with. Further, since the end of the water supply pipe 16 of the shower device 12 is constantly in pressure contact with the valve seat 15 and is closed, it is impossible to eject water from the shower device 12.

Therefore, when the on-off valve is opened by operating both or one of the handles 24, 25, the water flowing from the water discharge port 4 is discharged from the first flow passage 9 through the first flow passage 9 in which the cross-sectional area of the flow passage switching member 5 is small. It is jetted at high pressure to 7a, but the water is a shower device.
Since it is impossible to flow toward 12, the flow direction is changed and the water is discharged from the water discharger 23 through the second flow paths 10a and 10b (see FIG. 6).

As described above, with the water discharged from the water discharger 23, the operation tool 18 of the shower device 12 is pushed in, and the water supply pipe 16 is slid against the urging force of the spring 17 to cause the water supply pipe 16 to slide.
The end of the valve is separated and opened from the valve seat 15. Then, the water jetted at high pressure from the first flow passage 9 to the first outlet 7a travels at a high speed almost in the jetting direction and flows into the shower device 12.
Moreover, with the water flow ejected from the first outlet 7a at a high pressure, the air in the first outlet 7a in the peripheral portion thereof is caused to flow, and the air in the second flow paths 10a and 10b is sucked into a negative pressure. Because
From the second outlet 7b through the second flow paths 10a, 10b to the first outlet 7a
An air flow with a high pressure is generated.

As described above, when it is possible to eject water from the shower device 12, the water ejected from the first flow passage 9 to the first outlet 7a has a high pressure, and the water is ejected to the second flow passages 10a and 10b. Since an air flow having a high pressure in the same direction as the flow direction of the water is generated, there is no possibility that a part of the high pressure water ejected from the first flow path 9 against the air flow will flow toward the water discharger 23, and Is ejected from the shower device 12 (see FIG. 7).

When the water supply pipe 16 is brought into contact with and closed by the operation of the shower device 12 and the operating tool 18, the water ejected from the first flow path 9 to the first outlet 7a is discharged from the water discharge tool 23 via the second flow paths 10a and 10b. The flow path is switched as shown. That is, it is possible to change the flow path of water to the shower device 12 and the water discharger 23 only by operating the operation tool 18 of the shower device 12.

In the above embodiment, the faucet for mixing hot and cold water is explained.
It is also possible to implement the tap for water or hot water. Further, although the flow path switching member 5 has a structure separate from the faucet body A, the faucet body A and the flow path switching member 5 may be integrally formed.

[Effect of device]

As described above, in the faucet device of the present invention, the first flow path is independent from the inflow port of the flow path switching member to the first outflow port, and the second flow path is independent from the first outflow port to the second outflow port. The shower device provided with a normally closed on-off valve at the first outlet.
The water discharger is connected to each of the outlets, and the shower device and the water discharger are always in communication with each other through the second flow path.

Therefore, when the opening / closing valve of the faucet body is opened, water flows out from the first flow path to the first outlet and is discharged from the water discharger via the second flow path, but the first flow path and the second flow path are disconnected. The area is the inlet and the first,
Since it is formed smaller than the cross-sectional area of the second outlet,
Water is jetted from the first flow path to the first outlet with high pressure. However, as described above, when the opening / closing valve of the shower device is opened in a state where water is discharged from the water discharger, the water jetted from the first flow path to the first outlet advances toward the shower device, and Then, the second flow path becomes negative pressure, and an air flow flowing from the second outlet to the first outlet is generated.

Therefore, when the on-off valve of the shower device is opened, the first
Almost all of the water jetted from the flow passage to the first outlet is jetted from the shower device, and switching of the water flow passage between the water discharger and the shower device is performed by opening the normally-closed on-off valve of the shower device. It is possible to perform the switching of the flow paths extremely simply because it is possible to perform the switching. Further, since the opening / closing valve of the shower device is normally closed, the shower device can be efficiently used without unnecessarily ejecting water from the shower device.
