DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot / water mixer tap having a horizontal branch port, and more particularly to a single tap having a horizontal branch port (also referred to as a branch tap) using an existing hot / water mixer tap as it is. The present invention relates to a lever type hot / water mixer tap.

[0002]

2. Description of the Related Art Recently, a single lever type hot / water mixer tap (hereinafter simply referred to as a mixer tap) using two ceramic disks has been widely used.

[0003] The mixing stopper has a built-in bottomed cartridge body (cartridge method means a method of easily replacing consumables or built-in materials for each container), and a bottom plate of the cartridge body. A fixed disk and a movable disk are slidably joined and mounted on a barrel seat plate. On these disks, an operating disk integrated with the movable disk and having a mixing chamber on the lower surface. Is mounted on the operating disk, and the operating shaft is engaged with the operating disk, and the base of the single lever is engaged with the operating shaft.

[0004] The cartridge body is placed on a mixer tap body to which a long spout (approximately 30 cm) is attached, covered with a makeup cap (also called a makeup cover) from above, and fixed. I have.

[0005] A hose connected to a water purifier, a dishwasher or the like is taken out of the mixing tap, and when branching tap water or hot water, a branch cock is provided at an opening of the spout, and a hose is provided on the spout. Are connected.

Further, in order to connect a hose to such a mixing tap, there has been an apparatus in which the mixing tap main body is formed as a special body having a branch port, and a hose is connected to the main body with the branch port (for example, Japanese Patent Laid-Open Publication No. HEI 9-157556). And JP-A-63-66676).

However, in the case where the spout is connected to the hose, the spout swings in a range of about 180 °, so that the spout simultaneously expands and contracts, which is not preferable.

Further, a special main body with a branch port cannot be applied to an existing mixing tap.

Therefore, the inventor of the present invention has been keen to simply add a branch port to the mixing tap, and as a result, the mixing tap has no car.
Focusing on the fact that the mixing spout attached to the spout and the makeup cap covering the cartridge body are separated because the cartridge body is built in, a branch port is provided between the mixing spout body and the makeup cap. It was conceived to interpose a branch body with a separate body.

In order to fix the cartridge body to the mixer tap body, the cartridge body is placed on the mixer tap body, and then a decorative cap is screwed onto the mixer tap body and pressed and fixed from above. And a flange is provided on the upper surface of the cartridge body, and three (plural) long bolts are inserted through the flange from above, and the tips of the long bolts are screwed into the mixer tap body to form a car. At present, the method of fixing the cartridge body
Is being done.

The applicant of the present invention has disclosed a method of mounting a branch body having a branch port in the former method.

A proposal is made in Japanese Patent No. 3026769 and the like.

The present applicant has proposed the following with respect to a main body with a branch port having a branch port in a system similar to the latter (see Japanese Patent No. 2546893).

That is, this will be described with reference to FIG.
A fixed ceramic disk 2 having water holes and a movable ceramic disk 3 having water holes are slidably joined to a bottomed cartridge body 1 having a flange 10 on an upper surface (or an upper portion). The base of an operating lever (single lever) 5 is engaged via an operating shaft 20 with an operating disk 4 integrated on the movable ceramic disk 3 and having a mixing chamber on the lower surface. The operation of the operation lever 5 is for water discharge, mixing and water stoppage, and the water discharge is performed by a long spout 6 having a water discharge port at an obliquely upper position. The long branch body 8A in the axial direction is placed on the mixing stopper body 7A that has been placed so far, and the cartridge body 1 is placed again on the branch body 8A, and screwed through the flange 10 from above. With long bolt 9 Body 8A and mosquitoes - cartridge by joining a body 1 is fixed to the mixing valve body 7A, in the branch body 8A, water-in communication with the fixed and movable ceramic disk 2
In addition to penetrating through holes 13 and 14 for water and mixed water, a branch port hub (a hub is a portion close to a rotary fitting portion) 15 and a spout hub 16 are rotatably fitted to the outside, respectively. A branch joint 17 protrudes laterally from the branch port hub 15, and the branch joint 17 is connected to the through hole 1 for water.
3. The spout hub 16 communicates with the lateral hole 18 communicating with the spout hub 3.
A so-called stand-mounted type (also referred to as a deck type) single lever type hot and cold water mixing tap is proposed, in which the spout 6 is provided at the bottom and the spout 6 is communicated with the through hole 14 for mixed water through a horizontal hole 19. ing.

Incidentally, a cover of the cosmetic cover 21 which covers the cartridge body 1 and has an operating shaft 20 protruding therefrom.
The spout hub 16 is prevented from being pulled out by the spout portion. Reference numeral 22 denotes a water conduit.

[0015]

However, it has been found that the single lever type hot / water mixer tap having such a lateral branch port has the following problems.

A spout hub 16 is provided on the branch body 8A.
Therefore, the mixing spout main body having the existing spout hub fitted outside cannot be used.

Since the spout hub 16 and the branch port hub 15 are vertically adjacent to each other and externally fitted to the branch body 8,
A long spout 6 that is elongated in the axial direction, the height of the single lever-type hot and cold water mixing tap increases, and the head swings upward.
There is a possibility that the water spouts may scatter, and if there is a shelf or the like above, operation of the operation lever 5 in the vertical direction may be hindered.

In view of the above, according to the present invention, on the occasion of solving such a problem, the branch main body is made as simple and compact as possible.
It is an object of the present invention to reduce the cost of an attached branch faucet and to make it more versatile so as not to hinder its spread.

[0019]

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is a perspective view of the entire embodiment of the present invention, FIG. 2 is a main part view of FIG. 1, (A) is a plan view,
3B is a longitudinal sectional view, and the same or equivalent parts in the longitudinal sectional view of FIG. 3 showing a conventional example are denoted by the same reference numerals, and the description thereof will be simplified or omitted.

First, an outline of an embodiment of the present invention will be described.

In FIG. 1, a single lever type hot / water mixer tap 30 of the present embodiment with a stand is shown in FIG.
A fixed ceramic disk having a water passage hole and a movable ceramic disk having a water passage hole are slidably joined and housed in a cylindrical cartridge body having a flange at the upper side. Integrated on the top,
Further, the base of the operation lever is engaged with the operation disk having the mixing chamber formed on the lower surface via the operation shaft, and the operation lever performs spouting, mixing, and stopping water. Mixing stopper (3) with a long spout 6 located at
0), the mixer tap body 7 of the mixer tap (30);
The makeup cap 21 is separated, the cartridge body is removed, and the branch body 32 (see FIG. 2) is placed on the mixer tap body 7 together with the cartridge body, and a new, longer-sized cartridge is inserted. It is fixed with bolts 33.

That is, the tip of the existing long bolt having the flange inserted therein is screwed into the mixer tap body 7 using the screw hole which is newly inserted into the cartridge main body 7 with the other long bolt 33. The branch main body 32 is joined and fixed to the mixer tap main body 7.

Accordingly, since the long bolt 33 is formed as a bolt having a length penetrating both the axial length of the cartridge body and the axial length of the branch body 32, a new other long bolt is formed. Bolts.

Next, the decorative cap 21 made of synthetic resin is attached.

A thick ring-shaped branch port hub 15 is rotatably fitted to the branch body 32.
A branch port joint 17 screwed laterally to 5 allows its direction to be changed by 360 °.

The branch opening joint 17 is provided with a ceramic branch cock having a knob handle 34 (see Japanese Unexamined Utility Model Publication No.
The hose 37 is connected via a one-touch type joint (so-called click joint) 36 directly connected to the ceramic branch cock 35.

Therefore, according to the single lever type hot / water mixer tap 30 of this type with a base, the operation of discharging the hot water can be carried out in the same manner as the ordinary mixer tap (30).
Tap cock or tap water that leads to the cartridge body 35
Can be branched and guided to a water treatment device or the like via the hose 37 by the opening / closing operation of the mixer, and the existing mixing tap (30) can be used as it is without changing the mounting position or replacing parts. Diversification of applications can be achieved.

Here, the branch main body 32 of the embodiment of the present invention has the following size.

In FIG. 2, the branch body 32 and the branch port hub 15 fitted to the outside thereof are both made of metal. The former is a hollow cylindrical body formed by machining a free-cutting brass rod, and the latter is made of six types of bronze castings. It is a processed thick-walled ring body with a horizontal hole 1
8 synthetic rubber O-rings 38, 3
8 are interposed, and these are integrated so that they can be marketed and provided as attachment parts.

Since the outer diameter of the branch body 32 (for example, 52 mmφ or 50 mmφ) is formed to be the same as the outer diameter of the mixer tap body 7 of the existing mixer tap (30), the branch port hub 15 is branched. The main body 32 and the upper part of the mixer tap main body 7 can be fitted outside.

For this reason, the axial length (length in the axial direction) of the branch port hub 15 is lowered downward while the pair of upper and lower O-rings 38, 38 is formed as a seal holding cover with a minimum interval. It is dimensioned so that it can be extended and fitted over a part of the upper part of the mixer tap body 7.

Therefore, while minimizing the axial length of the branch port hub 15, the branch port hub 15 also comes into contact with the spout hub 16 to prevent it from falling off.

The outer diameter of the upper portion of the branch body 32 is slightly increased (for example, 53.5 mmφ for 50 mmφ) to form a stopper 45 for the branch port hub 15. Of the decorative cap 21 having an axial length of (6 mm) is formed so that the decorative cap 21 can be externally fitted to the decorative cap 21 from above. That is,
The outer diameter of the upper part of the branch body 32 is also made to match the inner diameter of the decorative cap 21. An O-ring 39 for retaining is interposed in the outer fitting.

On the other hand, a branch port joint 17 is screwed to the branch port hub 15.
Is a screw-in type pipe joint, that is, a type of union joint, and is composed of a union brim (bushing) 40 and a hexagonal union nut 41 rotatably fitted and engaged with the union brim 40. , This union brim 40,
It is screwed to a portion of the branch port hub 15 that faces the annular groove 42 formed on the tube axis of the horizontal hole 18 so that it can communicate with the horizontal hole 18.

Therefore, the union brim 40 includes:
A female screw and a male screw having different diameters are cut on the inner and outer surfaces, and are screwed to the branch port hub 15 so that the upstream connecting portion of the branch cock 35 can be screwed.

Therefore, the axial length (for example, 38 mm) of the branch port hub 15 is such that the hexagonal union nut 41 is screwed without rotating the branch cock 35.
What is necessary is just to have the substantially space which a spanner can be hung. Of course,
As the union nut 41, a standard product determined by the inner diameter of the lateral hole 18 is selected.

That is, the branch port joint 17 can use an inexpensive standard product.
8 has the same diameter as the communication hole provided in the union flange 40.

Therefore, the axial length of the branch body 32 is at least as follows: the decorative cap 21 does not fluctuate;
The union nut 41 is formed to have a size that is substantially the same as that of the spanner hook.

This outer fitting white can be formed by shifting the branch port hub 15 to the existing mixing plug main body 7, and thus it is not necessary to specially extend the outer fitting white. Therefore, the length of the branch body 32 in the axial direction can be made smaller than its outer diameter dimension, and as a result, it is flattened.

Therefore, in the branch main body 32 which is configured to be able to rotate the branch port joint 17, the axial length is particularly minimized, and the height of the mixer tap (30) having the branch port is increased. Can be suppressed.

Then, at the branch joint 17,
A water through hole 13, a mixed water through hole 14, and a hot water through hole 4 directly connected to the mixing tap body 7 and the cartridge body, respectively.
3 are provided to penetrate each.

A packing insertion groove is formed in the opening of the through hole on the side of the mixer tap body, and packings 44 and 4 are formed therein.
4 and 44 are fitted to form a seal at the time of joining with the mixer tap body 7.

[0044]

According to the present invention, the cartridge body is
A single lever type hot / water mixer tap which is fixed to the mixer tap body by a long bolt inserted through the flange above it, and the axial length of the branch body simply added to this is miniaturized. In addition, the height of the hot / water mixer tap is not increased in spite of the mounting type, so that it can be easily added to the existing hot / water mixer tap.

In particular, the outer diameter of the branch body having the branch port hub capable of changing the direction of the branch joint by 360 ° is made equal to the outer diameter of the existing mixer tap body, and the skirt portion of the decorative cap ( The lower part has an outer diameter that can be fitted, so
The axial length can be made smaller than the outer diameter, and as a result, the branch body can be minimized in size, and in turn, inexpensive and can be conveniently used as a branch faucet attachment.

Further, since the branch cock is directly connected to the branch joint, there is no fear of water leakage even if it is attached to an existing single lever type hot / water mixer tap as an unused attachment such as a water treatment device to be set in the future. Not at all.
