Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot and cold water mixing faucet for mixing and discharging hot water and water, and more particularly to the technical field of hot and cold water mixing faucet in which the mixing is performed by a single lever.

[0002]

2. Description of the Related Art A hot and cold water mixing faucet is a convenient one that can mix hot water and water and discharge hot water having an appropriate temperature.
In recent years, various types have been proposed. In particular, in recent years, a single handle (lever) is used to set the temperature of hot water and adjust the discharge amount of hot water.
A single-lever type hot and cold water mixing faucet that has become extremely simple has also been proposed. Such a single-lever type hot and cold water mixing faucet is operated by a single handle and has a control valve plate having a flow passage on the lower surface, and a hot water on the faucet body side that is arranged below the control valve plate. It is common to have a cartridge that incorporates a hot water supply port, a water supply port, and a fixed valve plate having a mixing outflow port, which are connected to a water supply port, a water supply port, and a hot water discharge port, respectively, and is built in the stopper body. The cartridge used in this case is a "side-out" in which the mixing outlet is opened laterally (see, for example, FIG. 6).
2) of the type shown in FIG. 7), and “downward return” (for example of the type shown in FIG. 7) in which the mixing outlet is opened downward.

In a hot and cold water mixing faucet attached to a top plate of a vanity or the like, its discharge pipe (faucet) projects toward the inside of the bowl of the vanity or the like so that hot water can be directly discharged from the pipe. In general, the discharge pipe is directly attached to the hot and cold water mixing faucet. In the following, such a type will be referred to as a discharge pipe integrated type.

On the other hand, a hot and cold water mixing faucet attached for washing hair on a dressing table or the like should be discharged from a separately prepared shower nozzle or other discharge pipe at a place relatively far from the hot and cold water mixing faucet. In general, the shower nozzle and the like are attached to the hot and cold water mixing faucet side through a long discharge pipe and a hose. In the following, such a type will be referred to as a separate type of discharge pipe.

As shown in, for example, Japanese Utility Model Laid-Open No. 2-144065 and FIG. 6, a single lever type hot and cold water mixing faucet with an integrated discharge pipe is used as a main body of a stopper fixed on a top plate of a vanity or the like. A discharge pipe is integrally formed on the side surface, and a cartridge incorporating a fixed valve plate and a control valve plate for appropriately mixing hot water is attached to the inside of the stopper body. This hot and cold water mixing faucet supplies water from the lower part of the stopper body and water and hot water supplied through the hot water supply pipe to the cartridge side, and an appropriate temperature is obtained from the discharge pipe below the cartridge. The adjusted hot water is discharged.

In the discharge pipe integrated hot and cold water mixing faucet shown in FIG. 6, if the discharge pipe is to be arranged above the cartridge, the drainage path from the discharge port of the cartridge to the discharge pipe becomes complicated. , It must be constructed so that the discharge pipe is located below the cartridge. Therefore, in the hot and cold water mixing faucet integrated with the discharge pipe, as shown in FIG.
As shown in Fig. 6, when using the lower return type cartridge, the cartridge has to be largely projected above the stopper body, and the appearance design is also limited. ing. Therefore, a "side-out" type cartridge is suitable for the hot and cold water mixing faucet integrated with the discharge pipe.

On the other hand, in the hot and cold water mixing faucet of the separate discharge pipe type,
As shown in Japanese Utility Model Laid-Open No. 2-71177 and FIGS. 7 and 8, a cartridge that discharges mixed water to the side is used, and hot water and water are supplied to the cartridge from below the top plate. The mixed hot and cold water is made to flow back to the inside of the stopper body, and is guided to a hose or the like to which a shower nozzle (not shown) is attached. That is, in the case of the above-described discharge pipe integrated type hot and cold water mixing tap, it suffices to discharge the mixed hot and cold water directly from the discharge pipe directly attached to the stopper body. A passage through which hot water flows down must be separately formed in the plug body. Therefore, in the hot and cold water mixing faucet using the “sideways” type cartridge, in order to guide the mixed hot and cold water to the lower part of the stopper body, as shown in FIG. 8, a part of the stopper body is swollen. Therefore, it is necessary to use this as a passage, and not only the defect at the time of casting is likely to occur, but also the appearance is not preferable. Therefore, as the discharge pipe separate body type hot and cold water mixing faucet, the "downward return" type cartridge is suitable.

The most important problem is that in these hot and cold water mixing faucets of the discharge pipe integrated type or discharge pipe separate type, in order to solve the above problems, a dedicated cartridge must be used for each of the discharge pipes. The manufacturing, product management, and installation of the cartridge for the integrated type or the separate type for the discharge tube had to be carried out individually.

Therefore, the present inventor has
Various ways to make a cartridge that can be shared as a part of the above-described discharge pipe integrated type and discharge pipe separate type hot and cold water mixing faucet, and can also simplify the casting work of the main body As a result of repeated examinations,
The present invention has been completed.

The above is the structure of the cartridge main body 100a, but the cartridge 100 of the present invention is such that the flow path conversion plate 60 is attached to the lower portion of the cartridge main body 100a by the outer housing 40. As shown in FIGS. 1 to 5, the flow path conversion plate 60 is a substantially disc-shaped member having an outer circumference substantially the same as the outer circumference of the housing 30, and as shown in FIG. It has a hot water flow path 61 and a water flow path 62 having the shape of, and a mixing flow path 63 having the shape of a substantially half circle. As shown in FIG. 1, the hot water flow path 61, the water flow path 62, and the mixing flow path 63 have an opening area that increases toward the bottom, and the discharge pipe integrated plug body 200a. Alternatively, it can communicate with the hot water supply port 211, the water supply port 212, and the hot and cold water discharge port 213 on the side of the discharge tube separate body plug body 200b. As shown in FIG. 4 or 5, packing 64a or 64b is arranged on the lower surface of the flow path conversion plate 60.
a and 64b seal between the flow path conversion plate 60 and the partition plate in the assembly part 220.

As shown in FIG. 1, the flow path conversion plate 60 and the cartridge body 100a described above are integrated with each other by assembling the discharge tube integrated plug body 200a or the discharge tube separate body plug body 200b. It is made by the outer housing 40 which is to be stored as it is in the attachment part 220.
That is, the outer housing 40 encloses the flow path conversion plate 60 and the cartridge main body 100a at the same time, and the outer peripheral surface of the outer housing 40 can be easily inserted into the assembly portion 220. In addition, the flow path conversion plate 6 of the present embodiment
In No. 0, as shown in FIG. 1, a positioning protrusion 70 projecting from this is integrally formed on the lower surface thereof,
This positioning projection 70 is provided with the discharge pipe integrated plug body 200a.
Alternatively, the discharge pipe-integrated plug body 200a or the discharge pipe-independent body plug body 2 is engaged with an engaging hole formed in a partition plate or the like in the assembly portion 220 of the discharge pipe-independent body plug body 200b.
Positioning with respect to 00b is possible.

Further, as shown in FIG. 2B, the flow path conversion plate 60 extends the lower end of the housing 30 of the cartridge body 100a below the fixed valve plate 20, and the housing 30 You may implement so that it may be provided in the lower part so that attachment or detachment is possible. In this case, the outer housing 40 is unnecessary, and the housing 30 has a diameter that fits into the housing portion 220.

At the lower end edge of the outer housing 40, as shown in FIG. 1, an opening 42 is formed so that a part of the mixing flow passage 63 on the flow passage converting plate 60 side faces. The opening 42 exhibits a substantial action when the cartridge 100 is applied to the discharge pipe integrated plug body 200a, and the discharge pipe 214, which is the hot and cold water discharge port 213 on the discharge pipe integrated plug body 200a side. The hot and cold water flowing through the mixing flow channel 63 of the flow channel conversion plate 60 is guided toward the hot and cold water discharge port 213 so as to "laterally eject" the hot and cold water from the discharge pipe 214 so as to face the inner end side of the hot water. . In this case, the flow path conversion plate 60
The lower end opening of the mixing flow channel 63 is a discharge pipe integrated plug body 20.
It is easily closed by the partition plate arranged in 0a, and no special member for closing is required. The outer housing 40 having the opening 42 is attached to the assembly portion 220 on the side of the discharge tube separate body main body 200b.
Since there is no opening on the side surface of the assembly portion 220 when assembled inside, the opening 42 of the outer housing 40 is closed by the inner surface of the side wall of the discharge pipe separate plug body 200b, and the flow passage conversion. The lower end of the mixing flow passage 63 on the plate 60 side is communicated only with the hot and cold water discharge port 213 to be connected to the shower nozzle 215.

There is an engaging portion 65 on the side of the flow channel conversion plate 60 in the engaging portion 41.
By engaging with each other, the flow path conversion plate 60 is integrated with the cartridge 100. That is, the flow path conversion plate 60 may be fixedly integrated with the lower portion of the outer housing 40 like the flow path conversion portion of the cartridge 100 according to the second aspect. In the cartridge 100 of the embodiment, the flow channel conversion plate 60 is detachable from the outer housing 40. This is made possible by the engagement portion 65 on the flow path conversion plate 60 side and the engagement portion 41 on the outer housing 40 side. Of course, these engaging portions 41 and 65 are only required to allow the passage conversion plate 60 to be freely attached to and detached from the outer housing 40. Therefore, the engaging portions 41 are shown in FIGS. 4 and 5. Such an engaging recess may be used, and the engaging portion 65 may be implemented as a protrusion that engages with the engaging portion 41. Conversely, on the contrary, the engaging portion 41 may be a protrusion that protrudes inward. Joint part 6
Of course, 5 may be embodied as an engagement groove for engaging this projection.

The cartridge 100 constructed as described above

According to the cartridge 100 assembled to the discharge pipe integrated plug main body 200a shown in FIG. 4, the hot water supply pipe 211a to the cartridge main body 100a is maintained while keeping the shape of the assembly portion 220 as it is.
It is possible to easily connect the water supply pipe 212a and the mixing outlet 23 on the fixed valve body 20 side to the discharge pipe 214. Further, according to the cartridge 100 assembled in the discharge tube separate body main body 200b shown in FIG.
Only by storing and assembling this in the assembly portion 220 of the separate plug body 200b of the discharge pipe, the hot water inlet 21, the water inlet 22 and the mixed outlet 23 on the cartridge body 100a side,
The hot water supply port 211, the water supply port 212, and the hot water drainage port 213 on the side of the discharge tube separate body plug body 200b can be easily connected, and the hot water drainage port 213 on the side of the discharge tube separate body plug body 200b is assembled. It is only necessary to form it on the partition plate located below the attachment part 220.

That is, the cartridge 10 according to the present invention.
What is important in 0 is, first of all, the septum-separated plug body 2
This means that the shape of the assembling portion 220 on the 00b side may be exactly the same as that on the side of the discharge pipe integrated plug body 200a, as shown in FIG. That is, according to the cartridge 100 of the present invention, it is not necessary to specially form a portion for sending hot water to the shower nozzle 215, unlike the conventional separate discharge tube type plug body shown in FIG. As shown in FIG. 5, the discharge tube separate body type plug body 200b can be made into a simple shape, and therefore, it is possible to prevent the occurrence of defects during casting of the discharge tube body type separate body 200b. is there.

Secondly, the cartridge 1
Since the flow path conversion plate 60 in 00 is removable from the outer housing 40 or the housing 30, if the hot water supply port 2 on the side of the discharge pipe separate body plug body 200b is used.
11, even if the positional relationship between the water supply port 212 and the hot and cold water discharge port 213 is different from that on the discharge pipe integrated plug body 200a side, each hot water flow path 6 having a shape corresponding thereto
1. Channel conversion plate 6 having water channel 62 and mixing channel 63
The cartridge 1 which can be easily converted to 0
This means that the cartridge main body 100a, which is the majority of the No. 00, or this and the outer housing 40 can be used as they are. That is, this cartridge 10
If 0 is applied to both the discharge pipe integrated plug main body 200a and the discharge pipe separate plug main body 200b, only the flow path conversion plate 60 needs to be replaced, and the above first important point. Therefore, the cartridge 100 is very useful.

The second important point is that, also in the cartridge 100 according to claim 2 in which the flow path converting portion is integrated with the lower portion of the outer housing 40, the outer housing 40 may be replaced. , The same can be said.
