However, in the above-mentioned conventional faucet device, since the casing member inserted inside the outer shell member is made of a resin material, the size and shape of the outer shell member can be adjusted according to the type of the faucet device. Therefore, it is necessary to prepare a mold for injection molding, which causes a problem that manufacturing cost is high.
Further, the resin casing member of the conventional faucet device has a problem that the strength is lower than that of the metal casing member and the durability due to aging or the like is also low. As a result, in order to ensure long-term safety, there is a problem that maintenance such as inspection and parts replacement is costly.

There is also a problem that the size of the casing member itself becomes large, or that it is easily affected by fluctuations in the copper price.
Further, in consideration of the circumstances of the faucet device that is constantly exposed to hot water, when a stainless steel material having high corrosion resistance is used as the casing member, there is a problem that it is difficult to process the stainless steel material with high processing accuracy.
Therefore, we have realized decopper alloys and decasts, utilized materials other than copper alloys, and have a degree of freedom in design while controlling manufacturing costs for various specifications depending on the type of faucet device. How to raise it has become an issue requested in recent years.

Further, in the case where the spout side flow path forming member is provided in the spout portion of the outer shell member in order to give the spout portion various functions, the outer shell member has conventionally supported the spout side flow path forming member.

Thereby, it is possible to effectively prevent the spout side flow path forming member 68 from coming out of the secondary side adapter member 64.
Further, since the locking member 62 is supported (for example, fixed) by the secondary side adapter member 64, the force at the time of locking is also supported by the casing member 40 via the secondary side adapter member 64, and the outer shell No undesired load is generated on the member 8.

The shape of the protruding portion 68f is preferably a flange shape because it is easy to manufacture, but at the time of filing the present application, other forms are not excluded.

When the locking member 62 is composed of a tubular member along the outer peripheral surface of the secondary adapter member 64 or a wall-shaped member having an arc-shaped cross section (for example, a C-shaped cross section), the faucet device 1 is downsized. Is not hindered (the faucet device 1 is prevented from increasing in diameter).

Further, as shown in FIG. 2, the fitting groove 62g of the locking member 62 of the present embodiment has a semicircular upper side and a rectangular lower side when viewed from the front of the groove, but the spout side flow path forming member 68 Other forms are not excluded as long as the shape or size allows the fitting of the portion adjacent to the spout side with respect to the protruding portion 68f and does not allow the passage of the protruding portion 68f.

The rib portion 68r is provided in the rib portion 68r, and the lower region of the rib portion 68r extends toward the secondary side adapter member 64 (the end of the spout side flow path forming member 68 on the secondary side adapter member 64 side). It extends toward the portion) and is in contact with the secondary side adapter member 64.
As a result, the rib portion 68r that comes into contact with the secondary side adapter member 64 functions like a "replacement rod", and the spout side flow path forming member 68 bends downward ("bows"). The occurrence of events can be effectively suppressed.

Further, according to the faucet device 1 according to the present embodiment, even if the lower casing member 72 is formed in a substantially cylindrical shape by a metal plate material or a pipe material and is initially in a smooth state without unevenness, it is mechanical. As the engaging means, the lower pin engaging hole 72a and the upper pin engaging hole 72b can be formed, respectively, by bending or drilling the side portion of the lower casing member 72.
Further, as shown in FIGS. 12 and 13, each of the engaging holes 72a and 72b of the lower casing member 72 has an inner peripheral surface thereof with respect to the axial direction of the lower casing member 72 (direction of the central axis A1). The projection surfaces S1 to S4 can be formed by projecting onto the vertical surface S0, and the pedestal member 16 and the primary side adapter member 50 are axially oriented with respect to the lower casing member 72 (in the direction of the central axis A1). It is possible to form a surface capable of mechanically engaging with the pedestal member 16 and the primary side adapter member 50 when the relative movement is attempted.
That is, as shown in FIGS. 12 and 13, the engaging holes 72a and 72b of the lower casing member 72 are projected onto the plane S0 perpendicular to the axial direction (the direction of the central axis A1) of the lower casing member 72. The fact that the projection surfaces S1 to S4 can be formed by causing the projection surfaces S1 to S4 means that the pedestal member 16 and the primary side adapter member 50 move relative to the lower casing member 72 in the axial direction (direction of the central axis A1). When attempted, the engaging holes 72a and 72b of the lower casing member 72 can be mechanically engaged with the pedestal member 16 and the primary side adapter member 50 via the mechanical engaging pins 58 and 60. It will also be possible to form a casing.
Therefore, the lower casing member 72 can hold the pedestal member 16 and the primary side adapter member 50 by the engaging holes 72a and 72b of the lower casing member 72 capable of forming such projection surfaces S1 to S4. Will be.
As a result, the lower casing member 72 is mechanically engaged in the lower pin engaging hole 72a of the lower casing member 72, the mechanical engaging pin 58 for holding the pedestal member, and the engaging hole 16e of the pedestal member 16. Together, it functions as a mechanical engaging means that makes it possible to hold the pedestal member 16.
Further, in the upper pin engaging hole 72b of the lower casing member 72, the mechanical engaging pin 60 for holding the primary adapter member, and the engaging hole 50e of the primary adapter member 50, the lower casing member 72 is a machine. It functions as a mechanical engagement means that makes it possible to hold the primary side adapter member 50 by target engagement.
As a result, even if the casing member 40 is formed in a substantially cylindrical shape by a metal plate material or a pipe material, the casing member 40 can surely hold the pedestal member 16 and the primary side adapter member 50.

Further, according to the faucet device 1 according to the present embodiment, as shown in FIG. 8, in particular, depending on the amount of heat of the hot water flowing in the hot water supply pipe 44, the hot water supply pipe 44 or the water supply pipe 46 around it, or , Each connected portion 44a, 44b of the hot water supply pipe 44 and each connected portion 46a, 46b of the water supply pipe 46 may move in the axial direction due to thermal expansion.
On the other hand, in the faucet device 1 of the present embodiment, as shown in FIG. 8, the connected portions 44a and 44b of the hot water supply pipe 44 and the connected portions 46a and 46b of the water supply pipe 46 are pedestal members. The connection receiving portions 16c and 16d of 16 and the connection receiving portions 50c and 50d of the primary side adapter member 50 can move within the range of the clearances d1 to d4 while maintaining a watertight state. As a result, it is possible to absorb the movement of the connected portions 44a and 44b of the hot water supply pipe 44 and the connected portions 46a and 46b of the water supply pipe 46 due to thermal expansion.

Further, according to the faucet device 1 according to the present embodiment, as shown in FIG. 9, the single lever cartridge 54 can be arranged on the bottom portion 74a of the upper casing member 74. As a result, the single lever cartridge 54 can be reliably held by the bottomed upper casing member 74.

Further, according to the faucet device 1 according to the present embodiment, as shown in FIG. 7, for example, when a single lever cartridge 54 having a relatively small plane cross-sectional size is used, the single lever cartridge 54 is used. Even when the size of the plane cross section (outer diameter D2) of the valve seat member 52 to which the 54 is connected is set to be relatively small, the outer diameter D1 of the primary side adapter member 50 is set to the outer diameter of the valve seat member 52. It can be set larger than D2 (D1> D2).
Therefore, in the primary side adapter member 50, it is possible to sufficiently secure a space in which each of the hot water supply pipe 44 and the water supply pipe 46 is connected in the axial direction.

Further, according to the faucet device 1 according to the present embodiment, the primary side adapter member 50 and the valve seat member 52, which are connecting members, are made of a resin material. Thereby, the primary side adapter member 50 and the valve seat member 52 which are inexpensive and lightweight can be provided, and the leaching performance can be ensured.

Further, according to the faucet device 1 according to the present embodiment, when the bottomed upper casing member 74 is formed, the metal plate material is drawn, so that there is no seam due to welding or the like. , Can be integrally formed in a bottomed cup shape.

Further, according to the faucet device 1 according to the present embodiment, the rotary engaging recess 8r provided on the inner peripheral surface of the lower end portion of the support column portion 8a of the outer shell member 8 and the flange portion of the secondary side adapter member 64. The rotationally engaging convex portion 64p provided on the outer peripheral surface above the 64f is engaged with the functional portion unit 19 in the rotational direction.
As a result, the outer shell member 8 and the secondary side adapter member 64 can rotate integrally with the functional unit unit 19. By rotating the outer shell member 8 and the secondary side adapter member 64 with respect to the functional unit unit 19, the direction of water discharge can be appropriately adjusted. As a result, the convenience of the faucet device 1 is enhanced.
Here, since the secondary side flow path 78 is shaft-sealed by the lower seal member 22 and the upper seal member 28, the outer shell member 8 and the secondary side adapter member 64 are rotated with respect to the functional unit unit 19. Does not interfere with anything.
Further, since the rotational force is directly transmitted between the rotational engagement recess 8r of the outer shell member 8 and the rotational engagement convex portion 64p of the secondary side adapter member 64, the transmission of the rotational force is transmitted to the spout side flow path. The occurrence of rattling is remarkably suppressed as compared with the case where it is performed via the forming member 68. A rotating engaging convex portion may be provided on the inner peripheral surface of the support column portion 8a of the outer shell member 8, and a rotating engaging concave portion may be provided on the outer peripheral surface of the secondary side adapter member 64.

Further, according to the faucet device 1 according to the present embodiment, the flange portion 64f is formed at the lower end portion of the secondary side adapter member 64, the flange portion 64f is placed on the pedestal member 16, and the flange portion 64f is placed on the flange portion 64f. The lower end of the support column 8a of the outer shell member 8 is placed on the outer shell member 8.
This prevents the strut portion 8a of the outer shell member 8 and the pedestal member 16 from directly rubbing against each other. Therefore, even if the support column portion 8a of the outer shell member 8 or the pedestal member 16 is plated or the like, there is no possibility that the plating will peel off.

Next, the faucet device according to the second embodiment of the present invention will be described with reference to FIGS. 18 and 19.
FIG. 18 is a central side sectional view of the faucet device according to the second embodiment of the present invention, and FIG. 19 is a perspective view of the secondary side adapter member of FIG.

A rotating engaging recess may be provided at the lower end of the upper secondary adapter member 164a, and a rotating engaging convex may be provided at the upper end of the lower secondary adapter member 164b.

Further, as shown in FIG. 18, the lower secondary side adapter member 164b is not involved in the secondary side flow path 78, that is, even if the lower secondary side adapter member 164b is replaced, a special adjustment work is performed. Not needed. Therefore, the height of the secondary side adapter member 164 can be easily changed by preparing the lower secondary side adapter member 164b having a different height and replacing them as appropriate.

The idea of changing the height in this way can also be applied to changing the height of the casing member. Here, a modified example in which the casing member is divided will be described with reference to FIGS. 20 and 21.

FIG. 20 is an exploded perspective view of the casing member of the modified example. 21 is a cross-sectional view taken along the line XXI-XXI of FIG. 20.
Here, in the casing member 140 according to the modification shown in FIGS. 20 and 21, the same parts as those of the casing member 40 of the faucet device 1 according to the first embodiment of the present invention shown in FIGS. 8 and 9 have the same reference numerals. , And these explanations will be omitted.

First, the casing member 140 shown in FIGS. 20 and 21 includes a lower casing member 172, an intermediate casing member 174, an upper casing member 74, and an upper annular member 76, respectively, from the lower side to the upper side.
That is, in the casing member 140 shown in FIGS. 20 and 21, the member corresponding to the lower casing member 72 of the casing member 40 of the faucet devices 1 and 100 described above is the substantially cylindrical lower casing member 172 and the lower casing member 172. The structure is different in that the intermediate casing member 174 is made of two metals.
Further, as the metal material of the lower casing member 172 and the intermediate casing member 174, a stainless steel material (for example, SUS304 or the like) having relatively high corrosion resistance and relatively high durability and strength is used. However, the metal material used for the casing member 140 may be another metal material of the stainless steel material 15 as long as it has a relatively high corrosion resistance and a relatively high durability and strength.
Then, as shown in FIGS. 20 and 21, the outer peripheral surface of the upper edge portion 172a of the lower casing member 172 and the inner peripheral surface of the lower opening end portion 174a of the intermediate casing member 174 are integrated with each other by welding or the like. It is connected to the.

It is connected to the.

Here, as shown in FIG. 20, in the lower casing member 172 before being welded to the intermediate casing member 174, a metal plate material or a pipe material having a size that can be inserted into the support column portion 8a of the outer shell member 8 is used. , The shape in cross-sectional view is formed in a substantially C shape. As a result, both side edge portions 172b and 172c of the lower casing member 172 are formed so as to have a predetermined distance d101 [mm] in the circumferential direction.
For example, when molding the metal lower casing member 172, the metal thin plate material is formed into a curved shape by bending such as roll molding, and finally, the outer shell member 8 is formed. It has a size that can be inserted into the support column 8a, and its cross-sectional view is formed into a substantially C-shape.
Alternatively, a metal pipe material having a diameter that can be inserted into the support column portion 8a of the outer shell member 8 is prepared in advance, and the pipe material is cut or cut to be formed in the support column portion 8a of the outer shell member 8.

After that, the inner end portion thereof engages with the engaging hole 16e on the side surface of the pedestal member 16.
Therefore, the lower casing member 172 is mechanically engaged with the lower engaging hole 172d of the lower casing member 172, the mechanical engaging pin 58 for holding the pedestal member, and the engaging hole 16e of the pedestal member 16. As a result, it functions as a mechanical engaging means that makes it possible to hold the pedestal member 16.

Next, as shown in FIGS. 20 and 21, the intermediate casing member 174 in the state before being welded to the upper casing member 74 is also made of metal with dimensions that can be inserted into the support column portion 8a of the outer shell member 8. It is formed into a substantially cylindrical shape by a plate material or a pipe material.
For example, when forming a substantially cylindrical metal intermediate casing member 174, the metal thin plate material is formed into a curved shape by bending such as roll forming, and finally, an outer shell is formed. It is formed in a substantially cylindrical shape with dimensions that can be inserted into the support column portion 8a of the member 8.
Alternatively, a metal pipe material having a diameter that can be inserted into the support column portion 8a of the outer shell member 8 is prepared in advance, and the pipe material is cut or cut to be formed in the support column portion 8a of the outer shell member 8. Adjust to the axial length dimension that can be inserted into.
That is, since the casting process using a mold or the like is not adopted when molding the metal intermediate casing member 174, the intermediate casing member 174 is used for each shape of the outer shell member 8 according to the type of the faucet device 1. There is no need to prepare a mold for molding.

Next, as shown in FIGS. 20 and 21, a plurality of engaging holes 174c penetrating in the radial direction are also formed on the side surface of the intermediate casing member 174 by drilling or the like.
As a result, as shown in FIGS. 20 and 21, the mechanical engagement pin 60 for holding the primary side adapter member is inserted into the engagement hole 174c from the outside to engage with the engagement hole 174c. After that, the inner end portion thereof engages with the engaging hole 50e on the side surface of the primary side adapter member 50.
Therefore, in the engaging hole 174c of the intermediate casing member 174, the mechanical engaging pin 60 for holding the primary side adapter member, and the engaging hole 50e of the primary side adapter member 50, the lower casing member 172 is mechanical. It functions as a mechanical engagement means that makes it possible to hold the primary side adapter member 50 by engagement.

According to the above-described modification, since the lower casing member 172 is formed in a substantially C-shape in the cross-sectional view thereof, a metal plate material is formed when the lower casing member 172 is formed in a substantially C-shape. It can be easily molded by a relatively inexpensive bending process.
Further, by changing only the lower casing member 172 formed by a relatively inexpensive bending process, it is possible to prepare various types of casing members 140 according to the types of the faucet devices 1 and 100. , It is also possible to realize further cost reduction.
Therefore, the degree of freedom in designing the faucet devices 1 and 100 can be improved, and the manufacturing cost can be suppressed.

In the faucet devices 1 and 100 according to the present embodiment described above, the mode in which the hot water supply pipe 44 and the water supply pipe 46 are separate members from the pedestal member 16 below the hot water supply pipe 44 has been described. Each of the supply pipe 44 and the water supply pipe 46 may be provided integrally with the pedestal member 16.
Further, in the faucet devices 1 and 100 according to the present embodiment, the mode in which the hot water supply pipe 44 and the water supply pipe 46 are separate members from each other has been described, but each flow path in each of the supply pipes 44 and 46 ( As long as the hot water supply flow path and the water supply flow path are independent of each other, the hot water supply pipe 44 and the water supply pipe 46 may be provided integrally with each other.

In the metal casing member 40 used in the faucet device 1 according to the embodiment of the present invention described above, the metal casing member 40 is generally made of a metal plate material or a pipe material having a size that can be inserted into the support column portion 8a of the outer shell member 8. The form formed in a cylindrical shape has been described.
However, in the present embodiment, the shape of the metal casing member is not necessarily limited to a perfect cylindrical shape continuously formed over the entire circumference, and may be a semi-cylindrical shape, or this semi-cylindrical shape. It may have a shape extending in the circumferential direction and less than a perfect cylinder, a shape less than a semi-cylinder, and the like. In short, the shape of the metal casing member may be at least a semi-cylindrical shape or a plate shape smaller than a semi-cylindrical shape.
