DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral branch opening attachment used for an existing single lever type hot / water mixer tap.

[0002]

2. Description of the Related Art At present, a valve seat having a water passage hole is provided in a cartridge body, and a fixed ceramic disk and a movable ceramic disk are slidably joined and mounted on the valve seat. A single lever type hot / water mixer tap which operates the movable ceramic disk by a single lever provided substantially horizontally above via a swingable operating shaft has become widespread (for example, Japanese Utility Model No. 1). No. 25818).

[0003] The car of such a single lever type hot / water mixer tap is used.
The cartridge body is housed in a bottomed cylindrical stopper body, and a water and hot water conduit extends downward from the stopper body.
A spout-equipped hub having a spout is fitted around the outer periphery of the stopper body so as to be freely rotatable, and the spout is configured to be long and discharges water and hot water.

[0004] The plug body is attached to a top plate or the like of a home sink, and is referred to as a deck type as distinguished from a wall-mounted type hot / water mixer tap attached to a wall surface.

[0005] By the way, a branch port is added to the existing single lever type hot / water mixer tap of this deck type so that water is supplied to, for example, a water purifier.

Conventionally, as the additional device, 1) a method of providing a branch port at the tip of a spout, 2) a method of providing a branch port in the middle of a water conduit, and 3) a method of providing a branch port in a plug body. Has been done. The method 1) is not preferable because the appearance is impaired and the spout cannot rotate freely, and the method 2) is extremely difficult if the water conduit is buried in the wall. Also, even if the water conduit is suspended in a sink cabinet etc.
Not only is it impossible for a layman to do the work, but for rental apartments, it is even more difficult due to unchanged contracts.

[0007] Therefore, the applicant of the present invention can use the existing mixing tap parts as much as possible in the method 3), making it possible for even a layman to perform the work, and easily restore the original mixing tap. The research and development of a lateral branch opening addition device (branch opening attachment) has been eagerly studied and proposed in Japanese Utility Model Publication No. 4-44944 and Japanese Utility Model Publication No. 7-5332.

In the former proposal disclosed in Japanese Utility Model Publication No. 4-44944, existing parts such as a cartridge body, a cosmetic cover, a hub with a spout, and a mounting base are used as they are.

In the existing single lever type hot / water mixer tap, a system is adopted in which the cartridge body is fixed by pressing with a decorative cover, that is, a cartridge holding cover. After the cartridge body is placed on the mounting base in a fixed position, the cartridge holding cover is screwed to the mounting base to fix the cartridge main body.

In order to add a lateral branch port, a new long branch main body, a cylinder externally fitted to the branch main body, and lightly rotatable externally fitted to the cylinder. Prepare a hub with a branch port, disassemble the mounting base and the cartridge holding cover, screw a cylinder into the mounting base, and place a long branch port body in this cylinder in place. After the existing cartridge body is placed at a predetermined position on the branch opening body, the cartridge holding cover is screwed to the cylinder to fix the cartridge body.

However, in the proposed cartridge body, the mixed water that has passed through the fixed ceramic disk and the movable ceramic disk once goes downward from the bottom of the cartridge body and passes through a water passage hole in the mounting base. Since the water is discharged through the spout, the mounting pedestal becomes thicker in the vertical direction. For example, if the mounting base is made of a bronze casting, the weight becomes large, and furthermore, it becomes bulky in the vertical direction.

For this reason, the bottom of the cartridge body is stopped from being integrated, and the mixed water is discharged from the peripheral surface of the cartridge body, and the mounting pedestal is formed in a thin plate shape. It is possible to improve the size and cost of the cartridge body. Such a car
When the cartridge body is configured as a cartridge, when the cartridge body is put into a hub with a spout, the entire cartridge body is included, and as a result, the hot and cold water mixing tap can be made slimmer.

[0013]

However, in the single lever-type hot / water mixer tap based on the above-mentioned idea, the outer ring is pivotally fitted to a newly prepared cylinder as disclosed in Japanese Utility Model Publication No. 4-44944. Even if the hub with branch port cannot be added as it is and can be changed to the structure to be added temporarily, the branch port is always fixed if the installation location of the water purifier etc. is decided, but the hub with branch port is always 3
It turned out to be a new problem that the connection part was not stable when the branch port was connected to a water purifier or the like by turning 60 ° lightly.

The present invention has as its main object to solve such a problem, and has an additional object to provide a component as light as possible which can be marketed as a single unit.

[0015]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to accommodate a fixed ceramic disk and a movable ceramic disk in a cartridge body, A long mixing spout with spout for operating a ceramic disc by a single lever via an operating shaft. After the cartridge body is accommodated in the stopper body, the cartridge holding cover is attached to the stopper body. The hot water mixer tap is screwed onto a cover male screw to form a fixed hot water mixer tap. When a horizontal branch port is added to the hot water mixer tap, the plug main body and the cartridge holding cover are disassembled.
In the one that provides a branch attachment in the meantime,
The branch port attachment, a thin branch port body,
The cover is formed integrally with the branch port main body,
A male screw similar to the male screw is formed on the upper outer periphery, and
A hub with a branch port provided laterally with a branch port, a ring-shaped nut provided below the hub with the branch port and screwed to the male screw for the cover, and suspended from the main body for the branch port. An existing mixing tap, wherein a mixing water chamber as large as possible is formed between the branch port main body and the spout inlet by being configured as a single component from hot water and a water connection pipe. It is in the branch opening attachment.

[0035]

According to the present invention, when a branch port attachment used for an existing single lever type hot / water mixer tap is set in the plug body, the branch port is fixed, so that a water purifier connected to the branch port is unnecessary. There is no unusual movement, and the water purifiers etc. are stabilized.

Since the branch opening body is made thinner and is integrally formed with the hub with the branch opening by casting, the weight can be reduced while the number of parts is reduced, and the finished part can be formed.

Since the connecting pipe of hot water and water is suspended from the main body for the branch port, the entire metal branch attachment is made as described above, while maintaining the outer diameter of the main body for the branch port and extending downward as it is. In addition to this, not only the weight can be extremely reduced, but also when using a normal hot and cold water mixing tap using a spout, the mixing water chamber can be enlarged, and the spout is now longer (for example, 25 cm). Because of the large capacity, once the hot and cold water is collected in this mixed water chamber, water is spouted out, and the mixing temperature becomes uniform, the sound of the valve opening becomes low and quiet, and In addition, the erosion of the member can be prevented by the high flow velocity flowing out of the mixed water passage 21.
