DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal branch opening which is added to 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, and a fixed ceramic disk and a movable ceramic disk are slidably joined and mounted on the valve seat. 2. Description of the Related Art A single lever type hot / water mixer tap which operates a movable ceramic disk with a single lever provided substantially horizontally above via a swingable operating shaft has become widespread.

In such a single lever type hot / water mixer tap,
The cartridge is housed in a cylindrical stopper body with a bottom, and a water and hot water conduit extends downward from the stopper body, and a hub having a spout is freely rotatable around the stopper body. The spout is configured to be long,
Hot water, water or hot water is spouted.

[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-out type (wall fixed type) water / 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, such additional devices include 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 (for example, And Japanese Patent Application Laid-Open No. 8-14421) are considered and implemented. The method 1) is not preferable because the appearance is impaired and the spout cannot rotate freely. The method 2) is extremely difficult when the water conduit is buried in the wall. Yes, and even when 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 method of 3) while leaving the existing mixer tap parts as much as possible, making it possible for an amateur to perform additional work, and easily restore the original mixer tap. A possible lateral branch opening addition device (branch entrance) has been intensively researched and developed, 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 above-mentioned Japanese Patent Application Laid-Open No. H8-14421, which was filed later by the present applicant,
Only the tap body and spout of the existing hot and cold mixing tap are used as they are, and a new branch port is added to this with a new cartridge and single lever.
Since a new cartridge or single lever adds a finished product that can be used alone, there is a problem that the cost is doubled.

However, such a problem does not exist in Japanese Utility Model Publication No. 4-44944 proposed by the present applicant.

That is, as shown in FIG. 5, a cylindrical rising portion 51 is integrally protruded from the center of the plug body 50, and a hub of a spout 52 is rotatably inserted into the cylindrical rising portion 51. ing. A male screw 53 is engraved on the outer periphery at the upper end of the cylindrical rising portion 51. In the original single lever type hot / water mixer tap, the male screw 53 is screwed with a cap body 55 covering a cartridge 54. It is a female screw.

Reference numeral 56 denotes an operating pin protruding from the cartridge 54, to which the base of the single lever 57 is connected.

In particular, the male screw 5 of the cylindrical rising portion 51
3 and a female thread engraved on the inner periphery of the lower end of the cylinder 58 are screwed, and a male screw engraved on the outer periphery of the upper end of the cylinder 58 and a female thread 59 on the inner periphery of the lower end of the cap body 55 are screwed. It is screwed.

A hub 61 of a joint 60 serving as a branch port, which can be connected to a hose or the like, is rotatably inserted into the outer periphery of the cylinder 58. A branch path body 62 is closely fitted in the cylinder -58.

The branch path body 62 includes a cartridge 54.
The tap water inlet 63, the hot water inlet 64, and the hot water outlet (not shown) are axially penetrated at the same position as the water holes formed in the fixed disk to form a lotus root hole. . That is, hot water, hot water and hot water vertical through holes are respectively formed.

The tap water inlet 63 and the hot water inlet 6
4, a lateral hole 65 is formed, a plug 66 is screwed into one lateral hole 65 and closed, and the other lateral hole 65 is
Through a hole 67 and an annular groove 68 of the cylinder 58, it communicates with the joint 60 serving as a branch port.

Therefore, according to the present invention, the plug body 5
Branching body 62 having a branching opening between 0 and cap body 55
Therefore, the branch path body 62 having the branch port can be added without any modification of the existing single lever-type hot and cold water mixing tap.

As a result, the apparatus becomes an inexpensive additional apparatus as a whole, and can be easily added by a layman as needed.

[0019]

However, the water / water mixer tap with a branch port added by such a proposal has been put to practical use and widely used at present, but the following new request has been made.

That is, for example, the added hot water mixer tap with a branch port as described above generally has the branch port communicated with the tap water inlet 63 and the plug 66 without the hot water inlet 64. I used it without thinking of changing the screw,
In a dishwasher or the like for disinfecting bacteria at 75 ° C. or higher, a new necessity of hot water flow is newly generated, and a necessity of switching from a tap water inlet 63 to a hot water inlet 64 is newly generated at home.

However, since the screw replacement of the plug 66 requires a small screw driver, the switching operation is troublesome.

In particular, the drill hole forming the lateral hole 65 is
Since the open positions of the tap water inlet 63 and the hot water inlet 64 are restricted by the positions of the water holes of the fixed disk of the cartridge 54, these inlets 63 and 64 may be used depending on the model.
In some cases, the drill hole cannot be drilled horizontally toward the center of the pipe, that is, the drill hole may be formed diagonally.
4) Even if it is flush with the inner surface, the other inlet (6)
3) There is a problem that the protrusion protrudes from the inner surface of the through hole without being flush with the through hole and disturbs the flow of the flow-through water.

The plug 66 has its head, O
When a plug 66 which requires a ring and a screw portion and which requires an axial length of this length is screwed, the thickness of the branch path body 62 between the outer peripheral surface thereof and the inlets 63 and 64 becomes insufficient. In some models, the plug 66 could not be screwed.

[0024]
