Description

The present invention relates to a faucet, and in particular to a faucet having a cover.

Automatic faucets have been known as water faucets for some time. These automatic faucets are equipped with a power source (battery), a detection sensor, an electromagnetic valve, water passage members, etc., and further equipped with a cover to house these components inside.

In addition, since automatic faucets are used by connecting them to a water supply pipe placed on a wall or the like, a connection part is formed in the water-passing member, and the water supply pipe must be connected to this connection part. Specifically, the water supply pipe is formed with a female thread, and the connection part of the water-passing member of the automatic faucet is formed with a male thread, and the two are connected by screwing them together.

Here, the work of connecting the water supply pipe and the connection part is performed using a tool (e.g., an adjustable wrench), so the water-passing member of the automatic faucet is formed with a tool hook for hanging the tool during work. This tool hook protrudes outward in the width direction from the cover, so that when the tool is hung on the tool hook, it does not hit the cover, preventing contact between the tool and the cover (water discharge part 5 shown in Figure 4 of Patent Document 1, however, the tool hook is not assigned a part number).

JP 2013-11150 A

As shown in FIG. 8(a), the tool is U-shaped, and when the tool is hung on the tool hanging part, there is a part where the tool is located opposite the top of the cover. In addition, since the connection work of an automatic faucet involves a rotational movement, the direction of the force applied to the tool is not constant, and when the tool is hung on the tool hanging part, the tool and the faucet may unintentionally move relative to each other. Specifically, if the tool moves downward (in the direction of the arrow) from the state shown in FIG. 8(a) relative to the cover, it will come into contact with the cover as shown in FIG. 8(b). In particular, the force applied to the tool becomes greater toward the end of the connection work, so the force with which the tool comes into contact with the cover becomes stronger, and the impact may cause the cover to deform. If this happens, the deformed cover may interfere with the member stored inside, making it difficult to attach or remove the cover. Note that this is not limited to automatic faucets, but applies to faucets equipped with a cover that stores a water-permeable member inside.

In view of the above problems, the present invention aims to provide a faucet that prevents unintended contact between tools and the cover when connecting a water supply pipe to a connector.

The faucet for solving the above problem comprises a water passage member having an internal water passage that connects the connection part to the water supply pipe with the water outlet, and a cover that houses the water passage member, the water passage member having a tool hanging part for hanging a tool when connecting the connection part to the water supply pipe, an end of the tool hanging part being located widthwise outboard of the cover when the tool hanging part is oriented in the width direction, and a cover protection part having an end located above or below the cover in at least one of the vertical directions when the tool hanging part is oriented in the width direction.

In the faucet, the cover protection portion is formed at a position that overlaps with the tool hanging portion in the axial direction.
In the faucet, the end of the cover protection portion has a flat surface.

In the faucet, the flat surface is an inclined surface that is inclined with respect to the width direction.
In the faucet, the cover protection portion is formed separately from the water-passing member.

This invention makes it possible to prevent unintended contact between tools and the cover when connecting the water supply pipe and the connector.

One embodiment of an automatic faucet 1 embodying the present invention will now be described with reference to Figs. 1 to 7. Fig. 1 shows a perspective view of the automatic faucet 1 attached to a wall, viewed diagonally from below and from the front. The automatic faucet 1 is connected to a water supply pipe (not shown) installed in the wall of a washbasin or sink, and discharges clean water (hereinafter simply referred to as "water") from a water supply source. In addition, a washbasin, sink, etc. (not shown) is located below the automatic faucet 1 to receive the discharged water.

As shown in Figure 1, when the automatic faucet 1 is attached to a wall, it is almost entirely covered by a cylindrical cover 2, with a detection sensor 41 and a water outlet 532 located below the tip side. A roughly conical decorative sleeve 3 is fitted onto the cover 2 to cover the base end of the cover 2. The automatic faucet 1 is a sensor detection type, and when the detection sensor 41 detects a hand or the like positioned below the water outlet 532, water is discharged, and when it no longer detects it, water discharge is stopped.

For the automatic faucet 1 and each of the components that make up the automatic faucet 1, Figs. 1 and 2 respectively specify the tip (side) and base (side), top (side) and bottom (side), and width directions. Specifically, the tip (side) and base (side) are the directions in which the cylindrical cover 2 extends, and this direction is also called the axial direction. The direction of the central axis 511s of the connection screw part 511, which will be described later, is parallel to the axial direction. Also, the direction perpendicular to the axial direction and the up-down direction (the left-right direction in Figs. 4(c), 5(c), and 6(c)) is called the width direction.

Figure 2 shows an exploded perspective view of the automatic faucet 1. The automatic faucet 1 is mainly composed of a cover 2, a decorative sleeve 3, a valve drive unit 4, a water-passing member 5, and a support member 6. The cover 2 is composed of a cover body 21 and a lid cover 22, and the valve drive unit 4, the water-passing member 5, and the support member 6 can be stored inside the cover 2. The cover body 21 is made of a metal such as stainless steel, and is cylindrical with both ends open. The lid cover 22 is disc-shaped with the same diameter as the outer diameter of the cover body 21, and is detachable from the tip opening of the cover body 21.

As shown in Figures 3(a) to (c), multiple openings (including notches) are formed on the circumferential surface of the cover body 21. First, as shown in Figure 3(a), a rectangular sensor opening 211 and a circular water outlet opening 212 are formed on the lower tip side of the cover body 21 in that order from the tip. Furthermore, multiple openings are formed around the circumferential direction on the base end side of the cover body 21.

As shown in FIG. 3(a), a water stop valve opening 213 is formed in the lower part of the base end side of the cover body 21. The water stop valve opening 213 is U-shaped and cut from the base end edge 214 of the cover body 21 toward the tip. As shown in FIG. 3(b), two protective part openings 215 are formed in the upper part of the base end side of the cover body 21. The two protective part openings 215 are rectangular and elongated in the width direction and cut from the base end edge 214 of the cover body 21 toward the tip, and are formed symmetrically with respect to a line (shown by a dashed line in FIG. 3(a) and FIG. 3(b)) that divides the cover body 21 in the width direction in a plan view (rear view). An upper through hole 216 is formed on the tip side of the cover body 21 between the two protective part openings 215.

As shown in FIG. 3(c), hanging openings 217 are formed on both sides of the base end of the cover body 21. The two hanging openings 217 are generally square-shaped and cut away from the base end edge 214 of the cover body 21 toward the tip, and are formed symmetrically with respect to a line (shown by a dashed line in FIG. 3(a) and FIG. 3(b)) that divides the cover body 21 in the width direction in a plan view (rear view). A side through-hole 218 is formed on the tip side of each hanging opening 217 in the cover body 21. As shown in FIG. 1 and FIG. 2, a resin protective cover 219 is attached to the opening edge of the sensor opening 211 of the cover body 21.

The valve drive unit 4 is a unit structure consisting of a detection sensor 41, a control board 42 with a control unit, a power supply (not shown), etc., and controls the water discharge of the automatic faucet 1. The valve drive unit 4 has a semi-cylindrical upper part because it is stored inside the cover body 21. The detection sensor 41 detects hands, etc., and is located below the tip of the valve drive unit 4. When stored in the cover 2, it is located opposite the sensor opening 211 as shown in Figure 1. The control board 42 with the control unit controls the opening and closing of the valve of the valve unit 52 based on the detection result of the detection sensor 41. The power supply supplies driving power to the detection sensor 41, etc., and is composed of a dry cell.

The water passage member 5 forms a water passage through which water is discharged from the water supply pipe in the automatic faucet 1. From the base end, the water passage member 5 is composed of a connection member 51, a valve unit 52, and a water discharge member 53.

Figure 4(a) shows a plan view of the connection member 51, Figure 4(b) shows a side view, and Figure 4(c) shows a rear view. Note that the cover 2 is shown in dashed lines in each figure. The connection member 51 is a member that connects the automatic water faucet 1 to the water supply pipe and has a water passage that sends water from the water supply pipe to the valve unit 52, and is made of a metal such as brass. From the base end side, the connection member 51 has a connection screw portion 511, a connection member main body 512, and an attachment portion 513 that are integrally formed.

The connection threaded portion 511 is cylindrical with a male thread 514 on the outer periphery, and has a water passage inside. The center of rotation when the male thread 514 of the connection threaded portion 511 is screwed into the water supply pipe is called the central axis 511s, and is shown by a long dashed line in Figures 4(a) and 4(b) and by a dot in Figure 4(c). The connection member main body 512, which has a water passage inside, is located at the tip of the connection threaded portion 511. The connection member main body 512 is formed with a tool hook 515 on which a tool, such as both jaws of a monkey wrench, can be hooked when connecting the automatic faucet 1 to the water supply pipe.

As shown in FIG. 4(a), the tool hanging portion 515 is configured to protrude outward on both sides in the width direction in a plan view, and is formed line-symmetrically with respect to the central axis 511s in the plan view. Also, as shown in FIG. 4(b), both ends of the tool hanging portion 515 in the width direction form flat hanging surfaces 515a. The distance between the hanging surfaces 515a is longer than the width of the cover body 21, more specifically, the width of the cover 2 at a position overlapping with the tool hanging portion 515 in the axial direction. The hanging surfaces 515a are formed line-symmetrically with respect to the central axis 511s in the side view shown in FIG. 4(b).

Furthermore, as shown in FIG. 4(c), the tool hanging portion 515 is configured to protrude outward in both width directions at intervals of 180 degrees with respect to the central axis 511s in rear view. Therefore, when the connection member 51 is stored in the cover 2, the tool hanging portion 515 faces outward in both width directions, and both hanging surfaces 515a are positioned protruding from the hanging portion opening 217 of the cover 2. In addition, the base end surface 515b of the tool hanging portion 515 is approximately flush with the base end edge 214 of the cover 2.

As shown in FIGS. 4( b ) and 4 ( c ), a water stop valve 516 is attached below the connection member body 512 , and can open and close the water passage within the connection member 51 .
As shown in FIG. 4(a), an upper screw hole 517 is formed facing upward on the top surface of the connecting member main body 512, and as shown in FIG. 4(b), a side screw hole 518 is formed facing outward in the width direction on the tip side of the tool hanging portion 515 of both side surfaces of the connecting member main body 512.

A roughly cylindrical attachment portion 513 is formed at the tip of the connection member body 512 so as to protrude in the axial direction, and a water passage is formed inside that communicates with the connection screw portion 511 and the connection member body 512.

The valve unit 52 shown in FIG. 2 has a water passage (not shown) inside, and an on-off valve (not shown) is arranged in the flow path. The on-off valve is composed of an electromagnetic valve, and is controlled to open and close by the valve drive unit 4. The water discharge member 53 has an elbow-shaped water discharge pipe 531 made of synthetic resin, and a water discharge port 532 made of metal. The water discharge pipe 531 has a water passage formed inside, and the base end of the water discharge pipe 531 is connected to the tip of the valve unit 52, and the cylindrical water discharge port 532 is detachable from the tip of the water discharge pipe 531.

Figure 5(a) shows a plan view of the support member 6, Figure 5(b) shows a side view, and Figure 5(c) shows a rear view. Note that the cover 2 is shown in dashed lines in each figure. The support member 6 serves as a support for the valve drive unit 4 and the water passage member 5, and can be stored within the cover 2 with the valve drive unit 4 and the water passage member 5 supported or attached, respectively. The support member 6 is integrally molded from thermoplastic resin.

The support member 6 is formed with a support frame 61, which is rectangular in plan view, on the tip side, and the valve drive unit 4 can be installed on this support frame 61 from above. The base end side of the support member 6 is formed with a semi-cylindrical shape that forms an upward arc as a whole, and a mounting part 62 is formed with a hollow lower part, and the water-passing member 5 can be mounted from below as shown in FIG. 2. The upper outer periphery of the base end side of the mounting part 62 is formed in an upward semicircular shape that follows the inner circumferential surface shape of the cover body 21, and a cover protection part 63 is integrally formed on the upper surface of the base end, which can be contacted with a tool when connecting the automatic faucet 1 to a water supply pipe.

The cover protection part 63 has a rectangular parallelepiped shape extending upward from the upper surface of the base end of the mounting part 62. The cover protection part 63 has two protrusions that are symmetrical with respect to a center line (shown by a dashed line in Figs. 5(a) and (c)) that divides the support member 6 in half in the width direction, and these are formed as a pair. Each protrusion of the cover protection part 63 has a rectangular shape that is long in the width direction in a plan view, and the upper protective surfaces 63a that form the ends of the cover protection part 63 are each flat surfaces. However, the two protective surfaces 63a are not parallel surfaces, but are inclined surfaces that are higher the closer they are to each other.

In addition, when the support member 6 is stored in the cover 2, the lowest part (the outer part in the width direction) of the protective surface 63a of the cover protection part 63 protrudes upward from the protective part opening 215 of the cover 2. The lowest part (the outer part in the width direction) of the protective surface 63a is located above the upper end of the outer peripheral surface of the cover 2, more specifically, above the upper end of the cover 2 at a position overlapping with the tool hanging part 515 in the axial direction. Here, above the cover 2 means above a virtual surface (see the dashed line in FIG. 6(c)) that is perpendicular to the hanging surface 515a of the tool hanging part 515 and in contact with the outer peripheral surface of the cover 2. In addition, the base end surface 63b of the cover protection part 63 is approximately flush with the base end edge 214 of the cover 2. A through hole 64 is formed on the tip side between the cover protection parts 63 on the upper surface of the support member 6.

Next, the assembly of the automatic faucet 1 will be explained. First, the valve drive unit 4 and the water passage member 5 are assembled to the support member 6. The valve drive unit 4 is assembled from above to the support frame 61 at the tip side of the support member 6, and the water passage member 5 is assembled from below to the mounting part 62 at the base end of the support member 6. The necessary wiring is also performed.

6(a) shows a plan view of the base end side of the cover 2 in which the valve drive unit 4, the water passage member 5, and the support member 6 are assembled and stored, FIG. 6(b) shows a side view, and FIG. 6(c) shows a rear view. The valve drive unit 4 is not shown. As shown in FIG. 6(a) and FIG. 6(c), the tool hanging portion 515 is positioned in a loose fit state in the hanging portion opening 217 of the cover 2. The distance between both hanging surfaces 515a of the tool hanging portion 515 is longer than the width of the outer peripheral surface of the cover 2 that overlaps with the tool hanging portion 515 in the axial direction, so that both hanging surfaces 515a of the tool hanging portion 515 are positioned protruding outward in the width direction from the outer peripheral surface of the cover 2. In addition, the base end surface 515b of the tool hanging portion 515 is approximately flush with the base end edge 214 of the cover 2.

The cover protection part 63 is positioned in a loose fit state in the protection part opening 215 on the upper surface side of the cover 2. Even at their lowest parts (outer parts in the width direction), both protection surfaces 63a of the cover protection part 63 are positioned higher than the upper end of the cover 2, which is at a position overlapping with the tool hanging part 515 in the axial direction. Furthermore, the base end surface 63b of the cover protection part 63 is approximately flush with the base end edge 214 of the cover 2. Therefore, the hanging surface 515a of the tool hanging part 515 and the protection surface 63a of the cover protection part 63 are positioned at the overlapping part in the axial direction.

In other words, at least a part of the protective surface 63a of the cover protection part 63 is located on the imaginary band connecting both hanging surfaces 515a of the tool hanging part 515 in the plan view shown in FIG. 6(a). Therefore, when viewed from the tool, the protective surface 63a of the cover protection part 63 is located at a position facing the tool when the tool is hung on the tool hanging part 515. Furthermore, the connection screw part 511 is located protruding toward the base end side from the base end edge 214 of the cover 2. The water stop valve 516 attached to the connection member 51 is located at the water stop valve opening 213 of the cover 2 and protrudes below the cover 2. In addition, the upper screw hole 517 of the connection member main body 512 faces the upper through hole 216 of the cover 2 and the through hole 64 of the support member 6, and the side screw hole 518 of the connection member main body 512 faces the side through hole 218 of the cover 2. Then, screws 7 are inserted into the upper through-holes 216 and the side through-holes 218 of the cover 2 to secure the cover 2, the water-permeable member 5, and the support member 6.

Next, we will explain the action of connecting the automatic faucet 1 to the water supply pipe. Note that in this state, the water outlet 532 and decorative sleeve 3 have not yet been attached, but for the convenience of explaining the process of connecting to the water supply pipe below, we will refer to it as the automatic faucet 1.

First, as shown in FIG. 7(a), the connection screw portion 511 located at the base end of the automatic faucet 1 is placed against the water supply pipe, and the tool is hooked on the hook surface 515a of the tool hook portion 515. In this state, the automatic faucet 1 is rotated together with the tool to screw the connection screw portion 511 into the water supply pipe. Note that the automatic faucet 1 may be screwed in by hand without using a tool at the beginning, and the tool may be used when the screwing is tight. When the automatic faucet 1 is screwed in with a tool, the force required for screwing increases gradually, so depending on the amount and direction of force applied to the tool, the tool may unintentionally move toward the cover 2. However, the protective surface 63a of the cover protection portion 63 is located above the cover 2 at a position opposite the tool. Therefore, as shown in FIG. 7(b), the tool comes into contact with the protective surface 63a of the cover protection portion 63 before it comes into contact with the cover 2, and even if the tool moves unintentionally with the tool hook portion 515, contact between the tool and the cover 2 is avoided.

Then, once the connection screw portion 511 is screwed into the water supply pipe using a tool, the decorative sleeve 3 is attached, and the water outlet 532 is attached, the installation of the automatic faucet 1 is complete. An abutment portion (not shown) is provided on the inner surface of the decorative sleeve 3. This abutment portion abuts against the side of the cover protection portion 63 when the decorative sleeve 3 is attached, and the decorative sleeve 3 is positioned by restricting rotation about the central axis 511s. The automatic faucet 1 can be removed by reversing the above connection procedure. Even if the tool unintentionally moves toward the cover 2, the tool will come into contact with the protective surface 63a of the cover protection portion 63 before it comes into contact with the cover 2, protecting the cover 2, as described above.

According to the automatic faucet 1 of the above embodiment, the following effects can be obtained.
(1) In the above embodiment, when the tool hanging portion 515 is oriented in the width direction, the hanging surface 515a, which is the end of the tool hanging portion 515, is located outside the cover 2 in the width direction. In addition, when the tool hanging portion 515 is oriented in the width direction, the cover protection portion 63 has a protective surface 63a, which is the end, located above the cover 2. Therefore, even if the tool hanging portion 515 and the tool move relative to each other during the connection work of the automatic faucet 1, the tool will come into contact with the protective surface 63a of the cover protection portion 63 before the cover 2, and unintended contact between the tool and the cover 2 can be prevented.

(2) The cover protection part 63 is formed at a position that overlaps with the tool hanging part 515 in the axial direction. Therefore, when the tool is hung on the tool hanging part 515, the cover protection part 63 is located in a position facing the tool, so that contact between the tool and the cover 2 can be prevented.

(3) The upper end of the cover protection portion 63 is formed as a protection surface 63a. Therefore, the cover 2 can be protected from tools over a wide area.
(4) The protective surface 63a of the cover protective portion 63 is an inclined surface inclined in the width direction, and in particular, both inner sides of the pair of protective surfaces 63a are higher upward. Therefore, the higher inner side of the two protective surfaces 63a is more likely to come into contact with a tool, and even if the protective surface 63a is deformed, it is more likely to deform toward the lower outer side, so that the cover protective portion 63 is less likely to be crushed. Since the cover protective portion 63 and its protective surface 63a are symmetrical with respect to the center line that divides the support member 6 in half in the width direction, the tool makes line contact with both inner sides of the highest of the pair of protective surfaces 63a parallel to the central axis 511s. Therefore, the torque when tightening the tool is less likely to be transmitted to the protective surface 63a than when the tool makes surface contact with the protective surface 63a, and deformation of the cover protective portion 63 can be suppressed.

(5) The cover protection portion 63 is formed separately from the water-permeable member 5. Therefore, if the cover protection portion 63 comes into contact with a tool and is deformed, it can be replaced separately from the water-permeable member 5.
(6) The cover protection portion 63 is positioned in a loose fit state in the protection portion opening 215 of the cover 2. Therefore, even if the cover protection portion 63 comes into contact with a tool and is deformed, the deformed cover protection portion 63 is unlikely to come into contact with the protection portion opening 215 of the cover 2.

(7) The cover protection part 63 is formed as part of the support member that is integrally molded from thermoplastic resin. Therefore, when a tool comes into contact with the cover protection part 63, the cover protection part 63 deforms to absorb the impact, thereby reducing the impact on the water-permeable member 5.

The above embodiment may be modified as follows.
Although the cover protection portion 63 is formed on the support member 6 , the cover protection portion 63 is not limited to being formed on the support member 6 , but may be formed on the connection member 51 .

- The cover protection part 63 may also be configured as a separate body independent of the connection member 51 and the support member 6. For example, a screw member or bolt member with a high head height may be used in the upper screw hole 517 of the connection member main body 512, and when screwed into the upper screw hole 517, it is made higher than the cover 2, and this screw member or bolt member may serve as the cover protection part 63. In this case, the upper through hole 216 of the cover 2 is made large enough to allow the head of the screw member or bolt member to fit loosely, so that when a tool comes into contact with the screw member or bolt member that is the cover protection part 63, the impact is not transmitted to the cover 2. In this case, since the top surface between the cover 2 and the connection member 51 is no longer present, it is preferable to fix it separately using a screw 7.

- The pair of protective surfaces 63a of the cover protective portion 63 may be parallel surfaces rather than inclined surfaces. Also, the protective surfaces 63a may not be flat but may be curved or uneven. It is sufficient that the tool hits the surface before the cover 2.

Although the two cover protection parts 63 are formed as a pair, a single cover protection part 63 may be used. It is sufficient that the protection surface 63 a of the cover protection part 63 is positioned above the outer circumferential surface of the cover 2 .
Although the cover protection portion 63 is provided above the cover 2 with the tool hook portion 515 facing the width direction, it may be provided below the cover 2 instead of above. In other words, the cover protection portion 63 may be configured to protrude below the lower end of the cover 2.

Next, the technical ideas that can be understood from the above-described embodiment and other examples will be described below together with their effects.
(a) The cover protection part is characterized in that it is made of a thermoplastic resin. Therefore, according to the invention described in (a), when the cover protection part comes into contact with a tool, the cover protection part deforms to absorb the impact, and the impact is less likely to be transmitted to the faucet.
