Description

TECHNICAL FIELD The present invention relates to a water faucet device, and more specifically to a water faucet device having an external appearance that defines a cross-sectional longitudinal direction and a cross-sectional width direction.

The shape of the spout of a faucet device greatly affects the appearance of the faucet device and determines the quality of the design. , a flat shape that defines the longitudinal direction of the cross section and the transverse direction of the cross section has been developed.

A faucet device having such a shape has a problem peculiar to a spout having a flat cross-sectional shape that the spout is easily deformed and easily damaged when a force is applied in the lateral direction of the cross-section. On the other hand, when the shape of the spout is considered to ensure the required strength, the shape of the spout is restricted, making it difficult to design thinner faucet devices with various designs.

As a water faucet device capable of ensuring necessary strength even when it has a cross-sectional appearance that defines the cross-sectional longitudinal direction and the cross-sectional width direction, there is a structure described in Patent Document 1, for example. In the water faucet device described in Patent Document 1, as shown in FIG. 13 (corresponding to FIG. 1 of Patent Document 1), the external appearance of the water faucet device having a cross-sectional longitudinal direction and a cross-sectional lateral direction constitutes the appearance of the water faucet device. Members 126 and 128, a spout 134 from which water is spouted, two water passage members 136 communicating the spout 134 and a water supply source that supplies water to the spout 134, and external members 126 and 128. and reinforcing members 138 and 140 that are provided inside to reinforce the appearance member.

As shown in FIGS. 1 to 10, the water faucet device 1 of the present embodiment is a water faucet device 1 that is used by being fixed to an installation surface on which a water supply section 51 and an electrical wiring connection section 71 are prepared. Specifically, for example, a cylindrical hole (generally φ25 or φ35) is opened (exposed) on the counter surface, which is an example of the installation surface, and the water supply portion 51 and the electric wiring connection portion 71 are provided in the hole. is accommodated, and the faucet device 1 of this embodiment is installed on the counter surface so as to cover the hole.

In this embodiment, it is assumed that the counter surface is a horizontal surface, and the upper side in FIG. 1, the direction in which the tip side of the faucet main body member 4 protrudes (the left front direction in FIG. 1) is the front side of the faucet device 1, and the opposite side (the right back direction in FIG. 1) is the rear side of the faucet device 1. described as a side. The counter surface is not limited to a horizontal surface, and can be set in any direction.

In the faucet device 1 of this embodiment, the faucet main body member 4 constitutes an appearance member. As particularly shown in FIG. 9, the faucet main body member 4 includes a pedestal portion 30 fixed on the counter surface so as to cover the hole, and a first thin portion defining the longitudinal direction and the lateral direction of the cross section. A spout 16 and a second spout 18 are provided.

The first spout 16 extends upward from the pedestal portion 30, and the second spout 18 extends in the front-rear direction while being bent substantially at right angles to the first spout 16. The two spouts as a whole extend substantially L when viewed from the side. A character-shaped thin portion is formed.

On the other hand, as particularly shown in FIGS. 1 and 9, the faucet body member 4 of the present embodiment includes an inner cover 26, an outer cover 28 attached to face the inner cover 26, a spout inner housing 33, and a spout outer housing 34 .

The inner cover 26 has a front surface portion 26A that forms the front surface of the first spout 16 and a lower surface portion 26B that forms the lower surface of the second spout 18 . The base end side (lower end side) of the front face portion 26A is connected to the pedestal portion 30 .

The pedestal portion 30 of the present embodiment has a substantially rectangular shape in plan view, and the pedestal portion 30 is fixed by welding or the like to a base plate or the like installed on the counter surface, for example.

The front surface portion 26A of the inner cover 26 has a curved surface 26AC that curves in a direction away from the surface of the outer cover 28 at the central portion in the longitudinal direction of the cross section, and rising portions 26AS that protrude toward the outer cover 28 on both sides of the curved surface 26AC. have. The curved surface 26AC is curved but extends along the longitudinal direction of the cross section as a whole.

The lower surface portion 26B of the inner cover 26 also has a curved surface 26BC that curves away from the surface of the outer cover 28 at the central portion in the longitudinal direction of the cross section, and raised portions 26BS that protrude toward the outer cover 28 on both sides of the curved surface 26BC. have. The curved surface 26BC is curved but extends along the longitudinal direction of the cross section as a whole. In particular, as shown in FIG. 1, the curved surface 26AC and the curved surface 26BC are curved smoothly and continuously, and the rising portion 26AS and the rising portion 26BS are also curved smoothly and continuously. The front end portion of the lower surface portion 26B of the inner cover 26 is connected to the rear end portion of the spout outer housing 34, as shown particularly in FIG.

The outer cover 28 has a rear surface portion 28A forming the rear surface of the first spout 16 and an upper surface portion 28B forming the upper surface of the second spout 18 . The base end side (lower end side) of the rear surface portion 28A is also connected to the pedestal portion 30 .

A rear surface portion 28A of the outer cover 28 is a flat surface extending linearly along the longitudinal direction of the cross section.

The upper surface portion 28B of the outer cover 28 is similarly formed of a flat surface extending linearly along the longitudinal direction of the cross section. The rear surface portion 28A and the upper surface portion 28B are continuously curved smoothly.

An internal space is defined between the inner cover 26 and the outer cover 28 by bonding the rising portions 26AS and 26BS of the inner cover 26 and the outer cover 28 to each other.

In particular, as shown in FIG. 9, the spout inner housing 33 and the spout outer housing 34 are overlapped vertically to form the spout 32 that spouts water downward. The spout inner housing 33 has a cross-sectional shape that follows the central region of the curved surface 26BC of the lower surface portion 26B of the inner cover 26. The spout outer housing 34 has a region corresponding to the spout inner housing 33. 2 It has a cross-sectional shape following the rest of the area of the spout 18 (lower surface portion 26B of inner cover 26 + upper surface portion 28B of outer cover 28) (see particularly FIGS. 2, 3 and 9). A region of the spout outer housing 34 that does not correspond to the spout inner housing 33 has a cross-sectional shape following the second spout 18 (see particularly FIGS. 2, 3 and 9).

Two metal water-permeable members 36 are inserted into the internal space defined by the inner cover 26 and the outer cover 28 . The water-conducting member 36 is generally made of a copper pipe material that has sufficient strength and durability and is easy to work. A temporary water storage area 34s reaching the water outlet 32 is formed in the spout outer housing 34, and the upper end of each water conducting member 36 communicates with the temporary water storage area 34s. In this embodiment, the temporary water storage area 34s is defined by a resin inner housing, and two water passage members 36 are watertightly connected or inserted at the rear side of the resin inner housing. A main water flow path 34c extends.

2 and 3, each water-permeable member 36 is bent so as to follow the bent portion between the second spout 18 and the first spout 16, and the first spout 16 and the pedestal portion 30 so as to follow the bent portion. That is, each water-permeable member 36 is formed by performing two bending processes.

As shown in FIGS. 2 and 3, the two water-permeable members 36 extend parallel to each other in the first spout 16 and the second spout 18. Inside, it extends radially around a branch connection member 60, which will be described later.

In the faucet device 1 of this embodiment, the branch connection member 60 is connected to the water supply section 51 installed in the cylindrical hole of the counter surface. The branch connection member 60 of the present embodiment includes a branch element that is connected to the water supply section 51 on one side and branches into two water supply flow paths 62 and 63 on the other side, and two water supply flow paths 62 and 63. and a connecting element connecting each to each of the two water-permeable members 36 are integrally constructed members.

More specifically, as particularly shown in FIGS. 4 to 7 , the branch connection member 60 provides a vertically extending channel 61 connected to the water supply portion 51 at its lower end, and the upper end of the channel 61 . It changes its direction in the horizontal direction at the side and branches in a V shape to provide two water supply channels 62 and 63 (function as a branching element). Further, the branch connection member 60 extends along the extension of the two water supply flow paths 62, 63 so that the two water flow members 36 can extend over the extension of the two water supply flow paths 62, 63. Connection spaces 64, 65 are provided (function as connection elements). As a result, the connecting spaces 64 and 65 extend radially from the flow path 61 in plan view, and the water-permeable members 36 extending in the same direction are inserted and welded.

Unlike the conventional connection adapter 160 (see FIG. 14), the branch connection member 60 is not large enough to block the cylindrical hole of the counter surface. Therefore, the electrical wiring 72 (feed line and signal output line) from the electrical wiring connection portion 71 installed in the cylindrical hole of the counter surface to the human body detection sensor 73 installed in the second spout 18 is connected to the counter surface. It can easily pass through the cylindrical hole and the pedestal 30 (see FIGS. 8 and 9).

The human body detection sensor 73 is, for example, a substantially rectangular parallelepiped (substantially rectangular in plan view) infrared proximity sensor, and as particularly shown in FIGS. 74b. As shown in FIGS. 1 and 12, the human body detection sensor 73 is arranged between the two water passages 34c of the resin inner housing that partition the temporary water storage area 34s.

The sensor holding member 74 has a pair of hook walls 74w whose upper ends are bent further outward on both sides of the area where the electric wiring 72 extending from the human body detection sensor 73 is placed. It is supported by the two water-permeable members 36 via. The sensor holding member 74 is detachable from the two water passage members 36 using the elasticity of the hook wall 74w.

Each hook wall 74w is located between the water passage member 36 and the electrical wiring 72 over substantially the entire length of the sensor holding member 74 in the front-rear direction, and also functions as a dew condensation prevention rib.

The sensor holding member 74 is also supported by the spout inner housing 33 via a face seal member 75 . The spout inner housing 33 is fixed to the spout outer housing 34 with two front and rear screws 76 .

In this embodiment, by removing the face seal member 75 and the spout inner housing 33, it is possible to access the area in which the sensor holding member 74 and the human body detection sensor 73 are housed and perform various maintenance work. Become. Therefore, it can also be said that the opening to the area (sensor housing area) is covered (covered) by the spout inner housing 33 .

Further, the human body detection sensor 73 of this embodiment defines a sensitive region (a region where a hand is intended to be held up) on the lower side (outside) of the spout inner housing 33. Window openings 75w and 33w, which are substantially rectangular in plan view and correspond to the surface seal member 75 and the spout inner housing 33, respectively, are provided in order to preserve the space up to the sensitive area and achieve higher sensitivity. there is

In addition, a reinforcing member 40 is provided at the bent portion between the first spout 16 and the second spout 18 . The reinforcing member 40 has six reinforcing ribs 44 that reinforce the faucet main body member 4, and a holding member 48 that is welded to the reinforcing ribs 44 and integrally holds the reinforcing ribs 44 (see FIG. 1 shows a state in which the six reinforcing ribs 44 and the holding member 48 are separated). Each reinforcing rib 44 is formed by cutting a plate material having a thickness T into a substantially L shape.

Six reinforcing ribs 44 are arranged along both sides of each of the two water-permeable members 36 . More specifically, two reinforcing ribs 44 extend inside each water conducting member 36 , and one reinforcing rib 44 extends outside each water conducting member 36 . A path for the electrical wiring 72 is secured between the two reinforcing ribs 44 on the central side.

The holding member 48 is formed of a plate material that is bent into a substantially L-shape when viewed from the side, and is arranged so that the bent portion corresponds to the bent portion of the faucet main body member 4 . The holding member 48 is arranged on the side of the outer cover 28 with respect to the reinforcing rib 44 .

The reinforcing member 40 of this embodiment is configured by welding six reinforcing ribs 44 and a holding member 48 . Six reinforcing ribs 44 are welded to the inner cover 26 with the two water-permeable members 36 accommodated therebetween. That is, the water faucet device 1 of the present embodiment separates the electric wiring 72 and the human body detection sensor 73 from the outer cover 28, and separates the other components (the inner cover 26, the two water passage members 36, The branch connection member 60, the reinforcing member 40, the spout outer housing 34, the sensor holding member 74, the face seal member 75, and the spout inner housing 33) are integrally assembled and shipped from the factory. .

When the water faucet device 1 of the present embodiment that has been shipped as described above is installed on a counter surface or the like, for example, an operator manually removes the end portion of the electrical wiring 72 by utilizing the rigidity of the electrical wiring 72 itself. The electrical wiring 72 is inserted between the two reinforcing ribs 44 (guide members) on the central side from the second spout 18 side to the first spout 16 side, with the connector 72c provided at the top. The interval between the two reinforcing ribs 44 on the center side corresponds to the width of the connector 72c, and the two reinforcing ribs 44 function as guide members that guide smooth sliding of the connector 72c. Then, the connector 72c is connected to the electrical wiring connection portion 71 inside the cylindrical hole (φ25 or φ35) opening on the counter surface (see FIG. 9). After that, while the position of the electric wiring 72 is adjusted as necessary, the branch connection member 60 is fitted into the water supply portion 51 in the hole, and the human body detection sensor 73 is positioned at a predetermined position on the sensor holding member 74. . Then, the pedestal portion 30 is fixed on the counter surface, and the outer cover 28 is adhered or the like to the inner cover 26 and the spout outer housing 34 .

Alternatively, when the human body detection sensor 73 and the electrical wiring 72 are detachable via a connector, the rigidity of the electrical wiring 72 itself can be utilized, for example, manually by an operator when installing on a counter surface or the like. Then, with the connector provided at the end of the electrical wiring 72 on the human body detection sensor 73 side leading, the electrical wiring 72 extends between the two reinforcing ribs 44 (guide members) on the central side to the first spout 16 side. to the second spout 18 side. (After the insertion, the connector at the end of the electrical wiring 72 on the human body detection sensor 73 side is connected to the human body detection sensor 73.)

FIG. 11 is a rear perspective view of the water faucet device 1 of this embodiment with the outer cover 28 cut away. 72c is schematically shown. FIG. 12 is a diagram corresponding to FIG. 11 showing the state after the electrical wiring 72 is inserted.

As shown in FIGS. 11 and 12, six reinforcing ribs 44 extend on the outer cover 28 side of the curved surface 26AC of the front surface 26A of the inner cover 26 of the water faucet device 1 of the present embodiment. A pair of inner ribs 81 (which are also guide members) and a pair of outer ribs 82 are provided. An inner rib 81 extends inside each water-permeable member 36 and an outer rib 82 extends outside each water-permeable member 36 . route of the connector 72) is secured. It is preferable that the reinforcing rib 44 and the inner rib 81 and/or the outer rib 82 are substantially continuous. may have been The inner rib 81 and the outer rib 82 are made of resin, for example, and fixed to the curved surface 26AC by adhesion or the like. Note that the electric wiring 72 may have a form in which a plurality of electric wiring elements are connected in series within the faucet main body member 4 .

According to the water faucet device 1 of the present embodiment installed as described above, since two water passage members 36 are provided, the diameter of each water passage member 36 for ensuring a predetermined flow rate of water is can be made smaller. The water from the water supply portion 51 is branched by the branch connection member 60 and supplied via the two water passage members 36 , joins in the temporary water storage area 34 s and is discharged downward from the water discharge port 32 . As a result, the faucet device 1 can be designed to be thinner while ensuring the necessary amount of water.

Further, according to the water faucet device 1 of the present embodiment, each of the branched water supply flow paths 62 and 63 is connected to each of the water flow members 36 inside the pedestal portion 30 of the water faucet device 1 instead of on the counter side. When the connection spaces 64 and 65 (connection elements) of the branch connection members are arranged to provide a seal member or a sufficient welding margin between each of the water supply flow paths 62 and 63 and each of the water flow members 36 Even so, the path of the electric wiring 72 from the electric wiring connection portion 71 to the thin portions 16 and 18 of the faucet device 1 through the pedestal portion 30 can be secured relatively easily (especially FIG. 8 and FIG. 9). As a result, while effectively presenting a thin appearance in the first spout 16 and the second spout 18 as thin parts, the electrical function is improved (in this embodiment, automatic faucet using the human body detection sensor 73 ) can be realized.

According to the water faucet device 1 of the present embodiment, since the human body detection sensor 73 is arranged between the two water passages 34c that supply water to the spout 32, the degree of freedom in thin design is increased. High convenience can be realized without major restrictions. In particular, in a configuration in which a temporary water storage area 34s is provided adjacent to the water discharge port 32, and each water flow path 34c supplies water to the temporary water storage area 34s, between the two water flow paths 34c and By arranging the human body detection sensor 73 at a position adjacent to or in the vicinity of the temporary water storage area 34s, it is possible to eliminate the need to extend the hand to an undesired extent below the spout 32, thereby enhancing convenience. can be provided (easy to use). Also, the extending direction of the water flow passage 34c is not complicated to an undesired extent. Furthermore, since the electric wiring 72 does not need to extend further to the tip side of the spout 32, the two do not overlap in the vertical direction, and the degree of freedom in thin design is not greatly restricted.

Thereby, the holding function of the human body detecting sensor 73 can be provided to the two tubular water-permeable members 36 through the sensor holding member 74, thereby simplifying the structure. In particular, since the sensor holding member 74 of this embodiment is attached to the water passage member 36 by utilizing the snap-fit coupling of the hook wall 74w, attachment and detachment work is easy. Even if the faucet main body member 4 (specifically, the spout inner housing 33 and the face seal member 75) is removed for maintenance work or the like, the human body detection sensor 73 is maintained in a held state.

Further, according to the faucet device 1 of the present embodiment, each hook wall 74w is positioned between the water conducting member 36 and the electrical wiring 72 over substantially the entire length of the sensor holding member 74 in the front-rear direction. It also functions as a dew condensation prevention rib. The metal water-conducting member 36 may cause condensation due to the temperature difference between the water flowing inside and the surrounding environment. can be reliably prevented from reaching the electrical wiring 72 .

Further, according to the water faucet device 1 of the present embodiment, when the electrical wiring 72 is inserted into the water faucet main body member 4, the two (a pair of) reinforcing ribs 44 on the central side and the pair of inner ribs 81 are aligned. Since both of them function as a pair of guide members and effectively guide the connector 72c at the tip of the electrical wiring 72, workability in assembling the water faucet device 1 is improved.

That is, according to the water faucet device 1 of the present embodiment, the electrical wiring 72 is guided by the reinforcing ribs 44 and the inner ribs 81 functioning as guide members during assembly, so that the water faucet main body member 4 has a longitudinal cross-sectional shape. Even if it has a thin portion that defines the direction and cross-sectional width direction, the electric wiring 72 can be relatively easily inserted so as to pass through the inside of the water faucet device main body 4 from the side of the spout 32. can be done. Further, since the reinforcing ribs 44 and the inner ribs 81 are provided inside the faucet body member 4, they do not adversely affect the design of the appearance.

As a result, the reinforcing ribs 44 can be configured to have a dew condensation prevention function (for example, resin coating: please confirm).

In addition, according to the faucet device 1 of the present embodiment, since the faucet body member 4 is made of metal (for example, it can be manufactured from a SUS plate material), it is possible to adopt a thinner structure without any strength problem. It is possible to realize a much thinner device and a more aesthetically pleasing design.

The metal faucet body member 4 picks up electromagnetic noise from the surroundings of the faucet device 1 and adversely affects the internal human body detection sensor 73 and the electrical wiring 72 compared to the resin-made faucet body member. There is concern that it may affect However, in the faucet device 1 of the present embodiment, the human body detection sensor 73 is arranged between the two water flow paths 34c, and the water passing through the two water flow paths 34c affects the human body detection sensor 73. Electromagnetic noise is effectively shielded, and the electrical wiring 72 is arranged between the two water-permeable members 36 so that the water passing through the two water-permeable members 36c causes electromagnetic interference to the electrical wiring 72. Noise is effectively shielded.

Further, the human body detection sensor 73 has a sensitive area defined on the lower side. In other words, the sensitive area of the human body detection sensor 73 faces downward in the same direction as the water discharge direction from the water discharge port 32 . Therefore, even if the distance between the human body detection sensor 73 and the spout 32 is short, the risk of erroneously determining that the water spouted from the spout 32 is a human body is reduced. In other words, malfunction of the human body detection sensor 73 is suppressed, and the need to extend the hand to an undesired extent below the spout 32 is eliminated, providing high convenience (good usability).

Further, according to the water faucet device 1 of the present embodiment, one end of each of the water passage members 36 may be terminated within the pedestal portion 30 of the water faucet device 1, so compared with the water passage member 136 of Patent Document 1, Therefore, the number of times of bending can be reduced by one (only two times). As a result, the working efficiency of the water-conducting member 36 is improved (required machining accuracy can be relaxed).

Further, according to the faucet device 1 of the present embodiment, since the branch connection member 60 has both the function as a branch element and the function as a connection element, when both functions are realized by separate members (however, At least at the time of filing of the present application, such an aspect is also included in the scope of the present invention). Moreover, since the assembling process is also simplified, the assembling work of the faucet device 1 becomes easier.

Further, according to the water faucet device 1 of the present embodiment, the two water-conducting members 36 are arranged in the connection spaces 64 and 65 of the branch connection member 60 in the vertical direction of the flow path 61 of the branch connection member 60 in plan view. radiating from the center.

By adopting such a layout, the shapes and sizes of insertion margins for inserting each of the water-permeable members 36 into each of the connection spaces 64 and 65 are appropriately adjusted so that the insertion margins can be passed through. It is easy to absorb shape errors after bending the water member 36 .

Further, according to the faucet device 1 of the present embodiment, the water passage member 36 and the branch connection member 60 (the connection spaces 64 and 65 thereof) are fixed by welding (including so-called brazing). As a result, further miniaturization is realized by suppressing the welding margin to a small size.
