Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes an existing faucet and attaches it to the cylindrical rising portion downstream of the valve seat of the faucet body, thereby improving the water flow path of the faucet body. This invention relates to an improved technology for branch faucets for configuring a separate flow channel.

As a technique for configuring another flow channel by using an existing faucet main body as it is, as seen in British Patent No. 1501161, the valve is attached to a cylindrical rising portion downstream of the valve seat of the faucet main body. A branch faucet block is screwed in contact with the valve seat, and the block has a water guide channel that communicates with the upstream flow channel via the valve seat channel, and an upper space of the channel that connects to the valve seat. The branch faucet has a water discharging channel that communicates with a downstream water channel, a valve seat is provided around the upper end of the water guiding channel, and a valve body that can freely come into contact with and separate from the valve seat. It is attached to the block so that the flow channel on the upstream side of the valve seat and the flow channel on the downstream side of the valve seat can be freely switched between a communicating state and a non-communicating state. When a branch pipe is connected for communication and a water stop valve is attached to this branch pipe, or when the water introduction channel and the water discharge channel of the block are configured to be closable with the valve body, the water stop valve connection A branch pipe is provided in communication with the upper space of the block, so that the branch pipe constitutes a flow channel separate from the flow channel of the faucet body itself that bypasses the flow channels of the water introduction and water discharge.

The conventional structure described above had the following drawbacks.

That is, when constructing a branch faucet, the branch faucet block is screwed onto the cylindrical rising portion of the faucet body in order to bring the gasket on the block side into close contact with the valve seat of the faucet body. However, the screwing relationship between the male screw on the block side and the external screw on the faucet body side is unstable, and therefore, the relative phase of the branch pipe with respect to the faucet body cannot be set arbitrarily. ,
In other words, there was a drawback that the branch pipe could not be attached to the faucet main body at an arbitrary phase.

The present invention has been devised in view of the above-mentioned circumstances, and the branch faucet according to the present invention has a hollow portion on the upper side of the side wall of a bag-shaped spindle shaft that is hollow inside and has an opening at the lower end. A water outflow hole communicating with the spindle shaft is provided, an annular packing is attached to the periphery of the opening of the spindle shaft, and the spindle shaft is screwed onto the cylindrical rising portion so as to be movable in the axial direction. The annular packing is configured to come into contact with and separate from the valve seat in the faucet body as it moves in the axial direction, while the nut member that covers the outside of the water outflow hole of the spindle shaft in a watertight state is attached to the cylinder. A joint member that is screwed onto the raised portion and covers the outside of the nut member in a water-tight manner is attached so as to be rotatable relative to the front nut member, and the water outflow hole of the spindle shaft is connected to the joint member. The nut member is characterized in that a hole is provided in the nut member to communicate with the wooden barrel outlet pipe.

According to the above configuration, in addition to the flow channel of the faucet body itself, the flow channel is communicated with the upstream side of the valve seat of the faucet body through the spindle shaft, the nut member, and the joint member, regardless of whether the flow channel is opened or closed. The flow channel can be formed into branches, and the screwing phase of the nut member with respect to the faucet body is indefinite, but since the joint member is provided so as to be freely rotatable relative to the nut member, the joint with respect to the faucet body is fixed. The mounting of the members allows the phase, that is, the water outlet direction of the branch faucet to be changed and set arbitrarily, and as a whole, the conventional drawbacks can be overcome with a simple technique.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is the existing faucet body, and the inner surface of the rising part 2 has a female screw 3.
However, a male thread 4 is provided on the outer surface, and the existing handle and spindle shaft can be removed to form a branch faucet according to the present invention.

Reference numeral 5 denotes a bag-shaped spindle shaft that is hollow inside (indicated by number 6) and has an opening 7 at the lower end, and the upper side wall 8 of the spindle shaft has a plurality of water outflow holes 9 communicating with the hollow portion 6. is the provision.

Reference numeral 10 denotes a male screw provided on a part of the side wall 8, which is screwed into the female screw 3 of the faucet main body 1.

11 is a handle fixed to the upper end of the spindle shaft 5 by a set screw 12; 13 is a rubber annular gasket fixed to the periphery of the opening 7 by, for example, baking; when the handle 11 is rotated, the female screw 3 male screw 10
The spindle shaft 5 moves in the direction of its axis by the screw engagement of the
A valve seat 14 provided in the faucet body 1 by the annular packing 13
However, it is possible to switch between the contact state and the separated state.

As the annular packing 13 is separated from the valve seat 14 due to the upward movement of the spindle shaft 5, the water guide channel on the upstream side of the valve seat and the water discharge channel on the downstream side of the valve seat communicate with each other, and the water discharge port 37 is connected to the water supply channel on the upstream side of the valve seat. A continuous flow channel of the faucet body 1 itself is formed.

Next, 15 is a nut member that covers the outside of the water outflow hole 9 of the spindle shaft 5 in a watertight state, and between the nut member 15 and the spindle shaft 5 and in the upper and lower parts of the water outflow hole 9, O-ring 35.3 for maintaining the watertight state
2, and a communication hole 17 is provided in a wall portion corresponding to between the upper and lower O-rings 35 and 32.

This nut member 15 is screwed onto the male screw 4 of the faucet body 1 via a packing 31.

A joint member 16 covers the outside of the communication hole 17 of the nut member 15 in a watertight state, and maintains the watertight state between the joint member 16 and the nut member 15 and also in the upper and lower portions of the communication hole 17. O-ring 34 for
, 33 are provided, and a hole 18 is provided in order to communicate the water outlet pipe portion 29 connected to the lateral side of the joint member 16 with the watertight portion formed by the upper and lower O-rings 34 and 33. , are formed on the wall 16a.

Thus, the hollow portion 6 of the spindle shaft 5, the water outflow hole 9, the communication holes 17, 1B of the nut member 15 and the joint member 16, and the pipe portion 29 connected to the joint member 16, A branched flow channel (separate from the flow channel connected to the spout 37 of the faucet body 1) is formed which communicates with the water guide channel on the upstream side of the valve seat.

In addition, in the case of a configuration in which the wall 16a is not provided, the communication hole 17 directly communicates with the pipe portion 29.

Now, the joint member 16 is rotatable relative to the nut member 15, and therefore, the direction in which water is led out by the pipe portion 29 of the branch waterway can be arbitrarily changed and set.

Incidentally, 36' is a retaining ring that prevents the joint member 16 from being withdrawn.

19, a water faucet body 20, a valve seat 21, a spindle shaft 22,
This is a conventionally well-known faucet having a gasket 23 and a handle 24, and its water inlet 25 is connected to the pipe portion 29 of the joint member 16 via a gasket 26.0 ring 27 and a nut 28.
The water outlet 30 is connected to a water pipe of a water heater, washing machine, etc. (not shown).

Therefore, in the illustrated state, the annular packing 13 and the packing 23 are in contact with the valve seats 14 and 21, respectively, so that water is not sent to any of the discharge holes 37 and the water outlet 30.

Next, when the nozzle 11 is rotated and the spindle shaft 5 is moved upward, the annular packing 13 is separated from the valve seat 14.
Water is discharged from the discharge port 37, and when the handle 24 is rotated in the opposite direction, the gasket 23 is separated from the valve seat 21, and the water is sent to the water transport port 30 and sent to a water heater, washing machine, etc. (not shown). .

Also, by rotating both handles 11 and 24, the annular gasket 13 and gasket 23 are moved to the valve seat 14, respectively.

21, water is sent to both the discharge port 37 and the water transport port 300.

In the above embodiment, as is clear from the drawings, the joint member 16 is provided with one pipe section 29, but according to the present invention, this pipe section is extended in two directions to form a so-called three-way discharge valve. (in the illustrated embodiment, a two-way discharge valve).

Since the present invention has the above-described configuration, the handle, spindle shaft, etc. are removed from the existing faucet main body, and the bag-shaped spindle shaft as described above is installed inside the faucet main body by using the faucet main body as it is. You can easily create a branch faucet by simply attaching the following.

Therefore, it has the advantage that replacing the branch faucet with a branch faucet is easy and can be done easily by a housewife, and is inexpensive since there are few replacement parts.In addition, the direction of the wooden barrel of the branch faucet can be changed at will. New and remarkable effects that can be set can also be achieved.
