EP-A-2586919

However, in the conventional water faucet device described above, the casing member inserted inside the outer shell member is made of a resin material. Accordingly, it is necessary to prepare a mold for injection molding, which raises the problem of high manufacturing costs.
Moreover, the resin-made casing member of the conventional water faucet device has a problem that its strength is lower than that of a metal-made casing member, and the durability against aging and the like is also low. As a result, in order to ensure long-term safety, there is a problem that maintenance costs such as inspection and parts replacement are costly.

On the other hand, if the casing member of a conventional water faucet device is cast using a metal such as a copper alloy that is different from the resin material, it will be necessary to take measures to restrict the elution of lead from the copper alloy. There is also a problem that the size of the casing member itself is increased, or a problem that it is easily affected by fluctuations in the copper price.
In addition, considering the fact that the faucet device is constantly exposed to hot water, if a stainless steel material with high corrosion resistance is used as the casing member, there is also the problem that it is difficult to machine the stainless steel material with high machining accuracy.
Therefore, we have realized the elimination of copper alloys and castings, and the utilization of materials other than copper alloys. How to raise it is an issue that has been requested in recent years.
Furthermore, in order to ensure the watertightness of the internal flow path of the casing member, it is necessary to provide a sealing member such as an O-ring inside the casing member. However, when a thin metal plate or pipe is used as the casing member, there is also the problem that it is difficult to form a groove for holding the seal member in the casing member by cutting or the like.

Next, the operation of the water faucet device 1 according to the first embodiment of the present invention described above will be described together with the assembling method and processing method of the water faucet device 1 .
First, according to the water faucet device 1 according to the present embodiment, when assembling the water faucet device 1, the inside of the substantially cylindrical strut portion 8a of the outer shell member 8 formed in a shape corresponding to the type of the water faucet device 1 is A generally cylindrical faucet function unit 18 is inserted against.
At that time, in the casing member 40 of the faucet function unit 18, the pedestal member is preliminarily connected via the mechanical engagement pin 58 for holding the pedestal member and the mechanical engagement pin 60 for holding the primary side adapter member. 16 and primary adapter member 50 can be retained. Thereby, the base member 16 and the primary side adapter member 50 can be axially connected via the casing member 40 .
In addition, the casing member 40 made of metal allows the axial direction between the base member 16 and the primary side adapter member 50 in the support 8a to correspond to the shape of the outer shell member 8 according to the type of the water faucet device 1. In addition, the strength of the internal structure of the faucet function unit 18 and the like inserted into the strut portion 8a of the outer shell member 8 can be increased.
Further, the metal casing member 40 may be formed in a substantially cylindrical shape by a metal plate or pipe so that it can be inserted into the strut portion 8a of the outer shell member 8 having a shape corresponding to the type of the water faucet device 1. can.
As a result, the casing member 40 can be molded for each shape of the outer shell member 8 according to the type of the water faucet device 1 compared to the case where the casing member 40 is injection-molded with a resin material or the case where the casing member 40 is cast-molded with a metal material. Since there is no need to prepare a mold for the casing member 40, the dimensions and shape of the casing member 40 can be easily adjusted by a relatively inexpensive processing method.
Moreover, since the casing member 40 is formed of a metal plate material or pipe material in a substantially cylindrical shape, the casing member 40 can be formed thin while maintaining necessary strength. Thereby, the internal dimensions of the faucet device 1 can be suppressed.
Furthermore, if a casing member 40 that is made common to some extent is prepared for the outer shell member 8 having various shapes according to the type of the water faucet device 1, the casing member 40 can be relatively cut by cutting or the like. It can be adjusted to a desired axial dimension by an inexpensive machining method. Accordingly, the axial dimension distance of the casing member 40 between the base member 16 and the primary side adapter member 50 can also be freely set according to the axial dimension of the casing member 40 . In addition, the casing member 40 can be easily assembled by simply inserting the casing member 40 with its axial dimension adjusted into the strut portion 8a of the outer shell member 8.

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

Furthermore, according to the water faucet device 1 according to the present embodiment, as shown in FIG. Even if the planar cross-sectional size (outer diameter D2) of the valve seat member 52 to which the valve seat member 54 is connected is set relatively small, the outer diameter D1 of the primary side adapter member 50 is equal 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 secure sufficient space for connecting the hot water supply pipe 44 and the water supply pipe 46 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.

Furthermore, according to the water faucet device 1 according to the present embodiment, when the bottomed upper casing member 74 is formed, the metal plate material is subjected to a drawing process, so that there is no seam due to welding or the like. , can be integrally formed in the shape of a bottomed cup.
As a result, there is no possibility that the water around the single lever cartridge 54 held by the upper casing member 74 will come into contact with the seams such as welds of the upper casing member 74 .
Therefore, the risk of the metallic upper casing member 74 being corroded can be reduced.

Furthermore, according to the water faucet device 1 according to the present embodiment, the inner seal member 80 is provided to keep the outer side of the single lever cartridge 54 and the inner side of the casing member 40 watertight, while the outer side of the casing member 40 is provided. and the inner side of the outer shell member 8 (the inner side surface of the secondary flow path forming member 62) and in the same position as the inner sealing member 80 in the axial direction of the casing member 40, the upper sealing member 28, which is an elastic member. Therefore, when the repulsive force of the inner seal member 80 acts on the casing member 40, the repulsive force of the upper seal member 28, which is an elastic member, also acts at the same time, canceling each other out. This effectively suppresses deformation of the casing member 40 even when the thickness of the casing member 40 is thin.
As a result, it is possible to improve the degree of freedom in designing the faucet device 1 while ensuring watertightness, and to suppress the manufacturing cost.

Further, according to the water faucet device 1 according to the present embodiment, the upper sealing member 28, which is an elastic member, is positioned between the outer side of the casing member 40 and the inner side of the outer shell member 8 (the inner surface of the secondary flow path forming member 62). It functions as an outer seal that keeps the space between the watertight. As a result, suppression of deformation of the casing member 40 and securing of watertightness can be achieved with a smaller number of parts.

Further, according to the water faucet device 1 according to the present embodiment, the casing member 40 has the flange portion 74b provided at the axial end thereof and protruding outward. Thereby, the strength in the lateral direction (radial direction) perpendicular to the axial direction of the casing member 40 can be improved, and the deformation of the casing member 40 is further suppressed. Thereby, it is possible to further suppress the occurrence of an adverse effect on the sealing accuracy.

Further, according to the water faucet device 1 according to the present embodiment, a threaded portion (female thread 76a) having a thread groove is formed integrally with the flange portion 74b by welding. As a result, it is possible to make it difficult for the influence of heat due to the welding process to be transmitted to the sealing members 22 , 28 , 80 of the casing member 40 . Therefore, the sealing members 22, 28, and 80 of the casing member 40 are less likely to be thermally deformed such as strain, and the sealing accuracy can be ensured.
