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, and there is a problem that the 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.

On the other hand, if the casing member of a conventional faucet device is cast using a metal such as a copper alloy different from the resin material, it is necessary to take measures to regulate the elution of lead components from the copper alloy. 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 a requested issue in recent years.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art and the problems requested in recent years, and can improve the degree of freedom in design and suppress the manufacturing cost. It is an object of the present invention to provide a plug device and a method for manufacturing the same.

In order to solve the above-mentioned problems, the present invention is a faucet device capable of discharging and stopping hot water obtained by mixing hot water supplied from a hot water supply source and water supplied from a water supply source. A pedestal member fixed to the installation surface on which the device is installed, an outer shell member having a substantially tubular support portion attached to the pedestal member, and an outer shell member inserted into the support portion of the outer shell member, one end side thereof is described above. A metal casing member fixed to the pedestal member and a hot water supply flow path provided inside the casing member and extending downstream from the pedestal member to form a primary side flow path for supplying hot water and water, respectively. And a single lever cartridge provided inside the water supply flow path and the other end side of the casing member, and adjusts the mixing ratio and flow rate of the hot water supply flow path and the hot water supplied from the water supply flow path. The single lever cartridge provided with the on-off valve and the single lever that enables the on-off valve to be opened and closed, and the hot water supply flow path and the water supply flow path provided inside the casing member. It has a connecting member for connecting each downstream end of the single lever cartridge and a fixing member for fixing the single lever cartridge to the connecting member, and the casing member is inside the support column of the outer shell member. It is formed of a metal plate or pipe material with insertable dimensions, and the casing member includes a casing member on the other side, a casing member on one side provided on one side of the casing member on the other side, and a casing on the other side. It has a casing shelf portion interposed between the member and the one-side casing member, and the connection member is a valve seat member on the other side of the casing shelf portion and one side of the casing shelf portion. The valve seat member and the primary adapter member have a primary side adapter member, and the valve seat member and the primary side adapter member are downstream ends of the hot water supply flow path and the water supply flow path while sandwiching the casing shelf portion between them. And the single lever cartridge are watertightly connected to each other, and an elastic surface sealing member on the other side is provided to seal the surface between the other side surface of the casing shelf and the valve seat member. The water faucet device is characterized in that a one-side elastic surface sealing member is provided for surface-sealing between one side surface of the casing shelf portion and the primary-side adapter member.

In the present invention configured as described above, when assembling the faucet device, the inside of the substantially tubular strut portion of the outer shell member formed into a shape corresponding to the type of the faucet device is generally at least semi-cylindrical. The metal casing member of the above is inserted. At that time, by using a metal casing member in advance, it is possible to determine the axial space and distance dimension in the strut portion according to the shape of the outer shell member according to the type of the faucet device, and to insert it into the support portion. It is possible to increase the strength of the internal structure.
Further, the metal casing member can be formed into a substantially semi-cylindrical shape by a metal plate material or a pipe material so as to be inserted into a support column of an outer shell member having a shape corresponding to the type of the faucet device. As a result, compared to the case where the casing member is injection-molded with a resin material or cast-molded with a metal material, a mold for molding the casing member can be obtained for each shape of the outer shell member according to the type of the faucet device. Since it is not necessary to prepare the casing member, the dimensions and shape of the casing member can be easily adjusted by a relatively inexpensive processing method.
Further, since the casing member is formed of a metal plate material or a pipe material into a substantially semi-cylindrical shape, the casing member can be formed thin while maintaining the required strength. As a result, the internal dimensions of the faucet device can be suppressed.
Furthermore, if a casing member that is common to some extent is prepared for the outer shell members having various shapes according to the type of the faucet device, it is only necessary to cut a part of the casing member. The dimensions can be adjusted to the desired axial dimensions by a relatively inexpensive processing method. Thereby, for example, the axial dimensional distance of the casing member between the pedestal member and the connecting member can be freely set according to the axial dimension of the casing member. Further, it can be easily assembled by simply inserting the casing member in a state where the dimensions in the axial direction are adjusted into the support column portion of the outer shell member.
As a result, the degree of freedom in designing the faucet device can be improved, and the manufacturing cost can be suppressed.

Further, in the present invention, the casing member is between the other side casing member, the one side casing member provided under the other side casing member, and the other side casing member and the one side casing member. The connecting member has a casing shelf portion interposed therebetween, and the connection member has a valve seat member on the other side of the casing shelf portion and a primary side adapter member on one side of the casing shelf portion. In the valve seat member and the primary side adapter member, the downstream ends of the hot water supply flow path and the water supply flow path and the single lever cartridge are made watertight with each other while sandwiching the casing shelf portion between them. It is designed to be connected, and an elastic surface sealing member on the other side is provided to seal the surface between the other side surface of the casing shelf on the other side and the valve seat member, and the casing shelf on the other side is provided. A one-side elastic surface sealing member is provided for surface-sealing between one side surface of the portion and the primary-side adapter member.
That is, in the present invention, the casing shelf portion is interposed between the other side casing member and the one side casing member, and the valve seat member and the primary side adapter member constituting the connecting member sandwich the casing shelf portion in between. Is adopted, the space between the other side surface of the casing shelf and the valve seat member is surface-sealed by the other side elastic surface sealing member, and the space between one side surface of the casing shelf and the primary side adapter member is the one side elastic surface sealing member. The surface is sealed with.
According to the configuration of the present invention, the repulsive force of the other side elastic surface sealing member acts on the other side surface of the casing shelf, and at the same time, the repulsive force of the one side elastic surface sealing member acts on one side surface of the casing shelf. By canceling each other out, even when the thickness of the casing shelf is thin, the deformation of the casing shelf is effectively suppressed.

In the present invention, it is preferable that the other side casing member and the casing shelf portion are integrally configured.
According to this, since it is not necessary to weld the casing member on the other side and the casing shelf portion, it is possible to reduce the risk of corrosion due to the welded portion coming into contact with water.

For example, the casing shelf can be formed by drawing. If drawing is used, it is possible to relatively easily form a bottomed cylindrical form (a bowl-shaped form) using a metal material.

Further, in the present invention, it is preferable that the other-side elastic surface sealing member and the one-side elastic surface sealing member are the same members.
According to this, in addition to being able to reduce the number of parts types, it is easy to adjust the balance between the surface sealing force acting on the other side surface of the casing shelf and the surface sealing force acting on one side surface of the casing shelf. ..

In this case, it is further preferable that the other-side elastic surface sealing member and the one-side elastic surface sealing member are arranged in the same direction in a plan view.
According to this, the surface sealing force acting on the other side surface of the casing shelf portion and the surface sealing force acting on one side surface of the casing shelf portion can be adjusted evenly (symmetrically) with each other.

Further, in the present invention, it is preferable that the valve seat member and the casing shelf portion are positioned with respect to each other, and the primary side adapter member and the casing shelf portion are also positioned with respect to each other.
According to this, the occurrence of misalignment of the other-side elastic surface sealing member with respect to the valve seat member and the casing shelf portion is suppressed, and similarly, the misalignment of the one-side elastic surface sealing member with respect to the primary side adapter member and the casing shelf portion is suppressed. Occurrence can also be suppressed.

Further, in the present invention, the valve seat member is provided with a holding groove for holding the other-side elastic surface sealing member, and the primary-side adapter member holds the one-side elastic surface sealing member. It is preferable that a holding groove is provided for this purpose.

Can be suppressed.

Further, in the present invention, the other-side elastic surface sealing member has an opening for hot water and an opening for water, and the one-side elastic surface sealing member also has an opening for hot water and an opening for water. It is preferable to have.
According to this, since the surface seal for the hot water passage and the surface seal for the water passage can be realized by a common elastic surface seal member, a casing member having a smaller diameter can be realized.

Further, as shown in FIGS. 7 to 9, in the mounting hole 74e of the bottom portion 74a of the upper casing member 74, a protrusion 52c protruding downward from the bottom surface of the valve seat member 52 above the bottom portion 74a is inserted, and then below the protrusion 52c. It is designed to be inserted into the mounting hole 50f of the primary side adapter member 50. As a result, the valve seat member 52 is fixed to the bottom portion 74a of the upper casing member 74.

Next, as shown in FIGS. 8 and 9, on the side surface of the upper casing member 74, a plurality of (for example, two) outflow holes 74f are formed adjacent to each other in the circumferential direction by drilling.

As a result, the inner peripheral surface of the lower upper seal holding member 26 is held at a position above the upper lower seal holding member 24 with respect to the outer peripheral surface of the upper casing member 74.
After these drilling processes, as shown in FIGS. 8 and 9, the outer edge and the lower edge portion of the bottom portion 74a of the bottomed cup-shaped upper casing member 74 is inside the upper opening edge portion 72c of the lower casing member 72. The outer edge and lower edge portion of the bottom portion 74a of the upper casing member 74 and the upper opening edge portion 72c of the lower casing member 72 are welded to each other in a state of being inserted into the lower casing member 72. As a result, the upper end of the lower casing member 72 and the lower end of the upper casing member 74 are integrally connected to each other.

Next, as shown in FIGS. 8 and 9, the upper annular member 76 in a state before being welded to the upper casing member 74 is made of metal with dimensions that can be inserted into the support column portion 8a of the outer shell member 8. It is formed in a substantially annular shape by a plate material or a pipe material.
For example, when molding a substantially annular metal upper annular member 76, a metal tubular material having a diameter that can be inserted into the support column 8a of the outer shell member 8 is prepared in advance, and the tubular material is cut. By processing or cutting, the length dimension in the axial direction that can be inserted into the support column portion 8a of the outer shell member 8 is adjusted.
That is, since the casting process using a mold or the like is not adopted when molding the metal upper annulus member 76, the upper annulus is formed for each shape of the outer shell member 8 according to the type of the faucet device 1. It is not necessary to prepare a mold for molding the member 76.

Next, as shown in FIGS. 8 and 9, a female thread 76a is formed on the inner peripheral surface of the upper annulus member 76 by female thread processing.

Further, as shown in FIG. 7, the outer diameter D1 of the substantially columnar primary side adapter member 50 is set to be larger than the outer diameter D2 of the valve seat member 52 (D1> D2).

Next, as shown in FIG. 7, a single lever cartridge 54 is arranged above the valve seat member 52 in the upper casing member 74.
Further, as shown in FIG. 7, above the single lever cartridge 54, the male screw 56a of the cartridge holding member 56 is screwed into the female screw 76a of the upper annular member 76, so that the single lever cartridge 54 becomes the upper casing member 74. It is held in a pressed state above the valve seat member 52 inside. That is, the cartridge holding member 56 is a fixing member for fixing the single lever cartridge 54 to the valve seat member 52.
At this time, as shown in FIGS. 5 and 7, the outlet 54g of the hot water mixing path 54f of the single lever cartridge 54 communicates with the outflow hole 74f of the upper casing member 74.

After flowing out to the road 64a, it flows out to the spout flow path 68a in the spout side flow path forming member 68.

Next, the operation of the faucet device 1 according to the first embodiment of the present invention described above will be described with reference to the assembly method and the processing method of the faucet device 1.
First, according to the faucet device 1 according to the present embodiment, when the faucet device 1 is assembled, the inside of the substantially cylindrical support column portion 8a of the outer shell member 8 formed into a shape corresponding to the type of the faucet device 1. On the other hand, a substantially cylindrical faucet function unit 18 is inserted.
At that time, in the casing member 40 of the faucet function unit 18, the pedestal member is previously interposed via the mechanical engagement pin 58 for holding the pedestal member and the mechanical engagement pin 60 for holding the primary side adapter member. Each of 16 and the primary side adapter member 50 can be held. As a result, the pedestal member 16 and the primary side adapter member 50 can be connected in the axial direction via the casing member 40.
Further, the metal casing member 40 is used in the axial direction between the pedestal member 16 and the primary side adapter member 50 in the support column portion 8a according to the outer shell member 8 having a shape corresponding to the type of the faucet device 1. In addition to being able to determine the space and distance dimensions of the outer shell member 8, it is possible to increase the strength of the internal structure of the faucet function unit 18 or the like inserted in the support column portion 8a of the outer shell member 8.
Further, the metal casing member 40 can be formed into a substantially cylindrical shape by a metal plate material or a pipe material so as to be inserted into the support column portion 8a of the outer shell member 8 having a shape corresponding to the type of the faucet device 1. can.
As a result, the casing member 40 is molded for each shape of the outer shell member 8 according to the type of the faucet device 1, as compared with the case where the casing member 40 is injection-molded with a resin material or cast-molded with a metal material. Since it is not necessary to prepare a mold for the casing member 40, the size and shape of the casing member 40 can be easily adjusted by a relatively inexpensive processing method.
Further, since 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 be formed thin while maintaining the required strength. As a result, the internal dimensions of the faucet device 1 can be suppressed.
Further, 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 faucet device 1, the casing member 40 can be relatively cut. It can be adjusted to a desired axial dimension by an inexpensive processing method. Thereby, the axial dimensional distance of the casing member 40 between the pedestal member 16 and the primary side adapter member 50 can also be freely set according to the axial dimension of the casing member 40. Further, the casing member 40 in a state where the dimensions in the axial direction are adjusted can be easily assembled by simply inserting the casing member 40 into the support column portion 8a of the outer shell member 8.
As a result, the degree of freedom in the design of the faucet device 1 can be improved, and the manufacturing cost can be suppressed.

Further, it is assumed that the lower casing member 72, which is the mechanical engagement means of the faucet device 1 of the present embodiment, is not provided with the pin engagement holes 72a, 72b and the mechanical engagement pins 58, 60. In this case, for example, when the casing member 40 is formed of a metal plate material or a pipe material in a substantially semi-cylindrical shape, particularly, the side portion of the lower casing member 72 is in a smooth state without unevenness. Will be. This causes a problem that it is difficult for the lower casing member 72 to hold the pedestal member 16 and the primary side adapter member 50.
Therefore, it is necessary to provide a surface or an engaging portion on the side portion of the casing member 40 by some means so that the pedestal member 16 and the primary side adapter member 50 can be mechanically engaged and held.
Therefore, 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, the lower casing member can be used as a mechanical engagement means. By bending or drilling the side portions of the 72, the lower pin engaging hole 72a and the upper pin engaging hole 72b can be formed, respectively.
Further, as shown in FIGS. 10 and 11, 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). By projecting onto the vertical surface S0, the projection surfaces S1 to S4 can be formed respectively, and the pedestal member 16 and the primary side adapter member 50 are axially oriented with respect to the lower casing member 72 (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 relatively moving.
That is, as shown in FIGS. 10 and 11, the engaging holes 72a and 72b of the lower casing member 72 are projected onto the plane S0 perpendicular to the axial direction (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 pedestal member 16 and the primary side adapter member 50 to move relative to the lower casing member 72 in the axial direction (direction of the central axis A1). When attempting to do so, 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. It will be like.
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 reliably 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. 6, 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. 6, 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. It is possible to move while maintaining a watertight state within the range of each clearance d1 to d4 in each connection receiving portion 16c, 16d of 16 and each connection receiving portion 50c, 50d of the primary side adapter member 50. 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. 7, 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, it is possible to provide the primary side adapter member 50 and the valve seat member 52 which are inexpensive and lightweight, and can also secure the leaching performance.

Further, according to the faucet device 1 according to the present embodiment, the metal casing member 40 has a lower casing member 72, a lower casing member 74, and an upper casing member 74a having a bottom portion (an example of a shelf portion) 74a, from the lower side to the upper side. Further, a lower elastic surface sealing member 81 having an upper annular member 76 and surface-sealing between the lower surface of the bottom portion 74a of the upper casing member 74 and the primary side adapter member 50, and a bottom portion of the upper casing member 74. An upper (other side) elastic surface sealing member 82 that surface-seals between the upper surface of the 74a and the valve seat member 52 is provided.
That is, in the present embodiment, the bottom portion 74a is interposed between the upper casing member 74 and the lower casing member 72, and the valve seat member 52 and the primary side adapter member 50 sandwich the bottom portion 74a in between.
