Description

  The present invention relates to a faucet device, and more particularly, to a faucet device provided on a wall surface that rises upward from a bowl, and a vanity equipped with the faucet device.

  At present, a faucet device provided on a wall surface rising upward from a bowl is widely used. In such a faucet device, since the faucet device is not installed on the upper surface of the bowl, the bowl can be designed to be clean.

In the faucet device provided on the wall surface that rises from such a bowl, as in Patent Document 1, a shelf portion that is formed to project forward from the wall surface, and is provided below the shelf portion, above the water discharge portion A water faucet device is also known that includes a storage portion that covers at least a part of the front.
Such a faucet device does not allow the entire water discharger to be seen by the user, and has a better design.
Also, since small items can be placed on the top surface of the shelf, for example, when washing the face, the user places small items such as glasses and cosmetics, using the so-called “slow placement operation” using the top surface of the shelf. It can be performed and is convenient for the user.

  However, the faucet device as in Patent Document 1 is fixed in a state where the water discharge portion is accommodated in the storage portion, and the direction of tap water discharged from the water discharge port cannot be changed. When cleaning the bowl, there was a problem of poor cleanability.

In order to solve the problem, like the faucet device disclosed in Patent Document 2, it is conceivable to make the water discharge part a pull-out type to improve the cleanability of the bowl.
A conventional pull-out faucet device will be described with reference to FIGS. FIG. 8 is a side view showing a conventional pull-out faucet device. FIG. 9 is a side view showing a state in which the water discharge head is pulled out in the faucet device of FIG. 8.

  As shown in FIGS. 8 and 9, a conventional water faucet device 100 includes a main body portion 102 that is installed on an installation surface S such as a sink or a vanity, and a water discharge head formed with a water discharge port 104 that discharges tap water. 106 (water discharger) and a predetermined connection axis P from this water discharger head 106, pass through the inside of the main body 102, the other end is connected to a water supply source (not shown), and the main body together with the water discharge head 106 And a flexible hose 108 drawn from the portion 102.

At the tip 102a of the main body portion 102, an annular connecting portion 110 is projected in a state of surrounding the flexible hose 108, and the cylindrical connecting portion 112 formed on the water discharge head 106 receives the annular connecting portion 110. The water discharge head 106 is held by the main body 102.
When removing the water discharge head 106 from the main body portion 102, the water discharge head 106 is moved in the direction of the connection axis P by the fitting distance D in which the tubular connection portion 112 of the water discharge head 106 receives the annular connection portion 110 of the main body portion 102. By pulling out, the water discharge head 102 can be removed from the main body 102.

JP 2003-184139 A JP 2007-85142 A

Here, in order to improve the cleaning performance of the faucet device described in Patent Literature 1, when the pull-out faucet device described in Patent Literature 2 is combined with the faucet device of Patent Literature 1, the opening formed on the wall surface An annular coupling portion is formed in the cylindrical coupling portion, and a tubular coupling portion formed at the rear end portion of the water discharging head is fitted into the annular coupling portion, whereby the water discharging head is held on the wall surface.
However, in the faucet device described in Patent Document 2, when the water discharge head stored in the storage portion is pulled out, the water discharge head is connected by the fitting distance D into which the cylindrical coupling portion of the water discharge head is fitted. It is necessary to pull it out forward in the direction of the axis P and remove it, resulting in poor workability and poor usability.

  In addition, in order to draw out the water discharge head that is fitted and held in the annular coupling portion of the opening in the direction of the connection axis P, a space is required to draw the water discharge head further forward from the held position. Therefore, it is necessary to enlarge the shelf forward to avoid interference between the water discharge head and the storage portion. For this reason, the above-mentioned shelf becomes large and the design becomes worse. Furthermore, since the shelf portion is increased in size, the cleaning area of the wash bowl that can be visually observed for the user to perform face washing and the like is also increased, resulting in a problem that the user's usability is deteriorated.

  Therefore, the present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a faucet device that has good design and is user-friendly.

  In order to achieve the above-described object, the present invention is a water faucet device provided on a wall surface that rises upward from a bowl, wherein a water discharge port for discharging tap water is formed, and a water discharge head that can be drawn out from the wall surface. The other end is connected to the water supply source through the opening formed in the wall surface, extending in the direction of the predetermined connection axis from the water discharge head, and is formed to protrude forward from the wall surface with the water supply hose drawn from the wall surface together with the water discharge head In the state where the water discharge head is stored in the storage portion, the storage portion is provided on the lower surface of the shelf, and stores the water discharge head so as to cover at least a part of the upper and front of the water discharge head. And a water discharge head having an outer peripheral surface formed around the connection axis, and the holding device has an outer peripheral surface of the water discharge head different from the connection axis. It is characterized by being configured to hold the that direction.

  In the present invention configured as described above, the water discharge head has an outer peripheral surface formed around the connection axis extending from the water supply hose, and in the state of being accommodated in the storage portion, the outer peripheral surface is connected to the connection axis. Is held by the holding device from a different direction. For this reason, when pulling out the water discharge head from the storage section, it is not necessary to once pull out the water discharge head in the direction of the connection axis to release the holding by the holding device, improving workability and convenience.

  Moreover, in the conventional water discharging apparatus, the water discharging head was hold | maintained at the base end part of the water supply hose, and the water discharging head was removed by pulling out the water discharging head in the direction of the connection axis which the water supply hose extends. Thus, in the conventional water discharge head supported at the base end portion of the water supply hose, the front of the water discharge head is covered by the storage portion because the water discharge head is pulled out in the direction of the connection axis when removing the head. If so, the water discharge head drawn out interferes with the storage section. In order to avoid this interference, a large gap is required between the tip of the water discharge head and the storage portion covering the front of the water discharge head, so that the storage portion of the water discharge head is enlarged. On the other hand, in the water faucet device of the present invention, since the outer peripheral surface of the water discharge head is held from a direction different from the connection axis, a large space for drawing the water discharge head from the holding position in the direction of the connection axis is unnecessary. Thus, there is no need to enlarge the storage part forward. Therefore, the above-mentioned dimensions of the shelf can be suppressed, and the design is good. Furthermore, since the above-mentioned dimensions of the shelf can be suppressed, a cleaning area of the bowl that can be visually observed for the user to perform cleaning can be secured widely, and the convenience of the user is good.

  In this invention, Preferably, a holding | maintenance apparatus is comprised so that it may assist pulling up a water discharge head toward a storage part, when a water discharge head is brought close to predetermined distance.

  In the present invention, the storage unit that stores the water discharge head is provided below the shelf, but when the water discharge head is stored in the storage unit, the storage unit is not visible to the user and is held by the water discharge head. There was a problem that the position was difficult to understand and the storage property was poor. In order to solve such a problem, in the present invention, the holding device is configured to assist the pulling-up head to be lifted toward the storage portion when the discharging head is brought close to a predetermined distance. Thus, when the water discharge head is brought close to the storage portion to a predetermined distance, the water discharge head is pulled up to the storage portion and guided to a predetermined holding position, and the outer peripheral surface thereof is supported by the holding device from a direction different from the connection axis. Thereby, storability improves and usability can be improved.

  In the present invention, preferably, further, an electromagnetic valve that switches water discharged from the water outlet, a human body detection sensor that detects the presence or absence of an object to be detected below the water outlet, and a manual operation device operated by a user The presence or absence of detection of an object to be detected by a human body detection sensor, or a control device that controls opening and closing of a solenoid valve based on an operation of a manual operation device, and whether or not a water discharge head has been removed from a storage unit. A holding detection sensor, and the control device does not open or close the electromagnetic valve based on the detection of the human body detection sensor when the holding detection sensor detects that the water discharge head is removed from the storage unit. .

  In the present invention, for example, when a user performs a face washing operation by placing glasses on the top plate of the shelf, it is difficult for the user who has removed the glasses to manually operate the water stoppage because the hand is difficult to see. There was a problem that it was not easy to use.

  Therefore, furthermore, based on the presence or absence of the detected object detected by the human body detection sensor, the human body detection sensor that detects the presence or absence of the detection object below the discharge port, the solenoid valve that switches the discharge water from the discharge port And a controller that controls the opening and closing of the solenoid valve, so that automatic water discharge is performed based on detection by the human body detection sensor. Thereby, since the user can start water discharge only by holding a hand over the water discharge head, the user-friendliness can be improved.

  However, when performing automatic water discharge based on the detection of the human body detection sensor, when the user pulls out the water discharge head and uses it, water discharge starts at a timing not intended by the user, and the water is discharged outside the bowl. There is a risk of tap water being accidentally discharged.

  In order to solve this problem, in the present invention, the control device does not open or close the electromagnetic valve based on the detection of the human body detection sensor when the holding detection sensor detects that the water discharge head has been removed from the storage unit. . Thereby, in a state where the water discharge head is pulled out from the storage unit, the control device controls the opening and closing of the electromagnetic valve based only on the operation of the manual operation device, so water discharge is performed at a timing not intended by the user. Can be prevented. Thereby, it is possible to prevent water from being accidentally discharged outside the bowl, and to improve the user-friendliness.

  In the present invention, preferably, the holding device is a metal plate provided in the shelf or the storage unit, and a holding unit that is provided in the water discharge head and exerts magnetism on the metal plate so as to lift the water discharge head toward the storage unit. The holding detection sensor is a magnetic sensor provided on the shelf or the storage unit for detecting magnetism from the holding magnet, and the magnetic sensor is a magnetic sensor from the holding magnet. Based on the detection, it is detected whether or not the water discharge head is removed from the holding magnet.

  In the present invention configured as described above, the holding device is provided on the metal plate provided on the shelf or the storage unit, and on the water discharge head, and is magnetically applied to the metal plate so as to lift the water discharge head toward the storage unit. The holding detection sensor is a magnetic sensor provided in the shelf or storage section that detects magnetism from the holding magnet, and the magnetic sensor is a magnetic sensor from the holding magnet. Based on the above, it is detected whether or not the water discharge head is removed from the storage unit. For this reason, the holding magnet of the holding device can also be used as a magnet for detection by the magnetic sensor, and it is not necessary to newly provide a magnet to detect the state in which the water discharge head is pulled out from the storage portion, and the structure is simplified. be able to.

  The present invention is also a bathroom vanity provided with the faucet device of the present invention and a bowl from which tap water is discharged from the faucet device.

FIG. 5 is a side cross-sectional view showing a state in which the water discharge head of the faucet device provided in the vanity of the present embodiment is pulled out from the storage unit. FIG. 6 is a diagram illustrating a state in which the water discharge head of the faucet device provided in the vanity of the present embodiment is being stored in the storage unit.

As shown in FIGS. 2 and 4, the shelf portion 12 includes a structural plate 12 a made of a metal plate, a decorative plate 12 b that covers the top surface of the shelf portion 12, and a shelf cover that is disposed below the structural plate 12 a. 12c.
The structural plate 12 a is a steel plate bent into an L shape, and its short side is fixed to the wall surface 10, thereby giving rigidity to the shelf portion 12. Note that the flexible hose 36 extending from the water discharge head 14 extends to the back side of the wall surface 10 through the short side portion of the structural plate 12a.

The decorative plate 12b is a flat plate member that forms the appearance of the top surface of the shelf portion 12.
The shelf cover 12 c is a substantially rectangular parallelepiped member that configures the appearance of the front surface and the lower surface of the shelf portion 12. Housed in the shelf cover 12c are a human body detection sensor 22 disposed on the lower surface side of the shelf 12, the flow control / temperature control valve 30, and the like. Moreover, the center part of the shelf cover 12c is notched, and the water discharge head 14 is accommodated in this notch.

  The water discharge head 14 includes an appearance member 38, a first water passage member 40 a, a second water passage member 40 b, a third water passage member 40 c, and a holding magnet 42. In addition, a flexible hose 36 that is a water supply hose is connected to the water discharge head 14, and the flexible hose 36 extends in the direction of the connection axis P from the rear end portion of the water discharge head 14.

  The appearance member 38 is a substantially cylindrical resin member, and extends so as to surround the connection axis P. The outer appearance member 38 has a distal end portion bent downward, and the water discharge port 20 of the water discharge head 14 is provided at the bent distal end.

  The first water passage member 40a is a resin member disposed inside the appearance member 38, and has a water passage that extends in the direction of the connection axis P and is bent downward. Moreover, the flexible hose 36 is connected to the rear-end part of the 1st water flow path member 40a, and the hot water supplied from the flexible hose 36 flows into the water flow path inside the 1st water flow path member 40a. That is, one end of the flexible hose 36 is connected to the first water passage member 40 a of the water discharge head 14, extends from the first water passage member 40 a in the direction of the connection axis P, and passes through an opening formed in the wall surface 10. The other end is connected to the flow / temperature control valve 30 (FIG. 3).

  The second water passage member 40b is an annular resin member that is disposed inside the appearance member 38 and attached to the tip of the first water passage member 40a. Further, the third water passage member 40c is an annular resin member that is disposed inside the appearance member 38 and is attached to the downstream side of the second water passage member 40b, and the downstream end thereof becomes the water discharge port 20. ing. Accordingly, the hot water adjusted in temperature by the flow control / temperature control valve 30 passes through the flexible hose 36, passes through the first water passage member 40 a, and is discharged from the water discharge port 20 of the water discharge head 14. In the present embodiment, the connection axis P is oriented in the front-rear direction perpendicular to the wall surface 10.

  The holding magnet 42 is a substantially rectangular parallelepiped magnet, and is disposed between the appearance member 38 and the first water passage member 40 a and above the connection axis P. Two holding magnets 42 are arranged in the direction of the connection axis P.

  As described above, the shelf cover 12c disposed on the lower surface of the shelf portion 12 is cut out at the center, and the water discharge head 14 is accommodated in this portion. Therefore, the part where the shelf cover 12c is cut out on the lower surface of the shelf portion 12 functions as the storage portion 44 (FIG. 5) of the water discharge head 14. The water discharge head 14 that is not pulled out from the wall surface 10 is stored in the storage portion 44, and in this state, at least a part above and in front of the water discharge head 14 is covered. Therefore, the entire water discharge head 14 is not visible to the user by the storage portion 44, and the design of the faucet device 4 is good.

  In addition, in this embodiment, although the storage part 44 is formed in the part by which the shelf cover 12c is notched on the lower surface of the shelf part 12, it covers so that at least one part above and the front of the water discharge head 14 may be covered. The shelf 12 may be provided on the lower surface of the shelf 12 separately from the shelf 12.

  By cutting out the shelf cover 12 c of the shelf portion 12, the metal structural plate 12 a is exposed downward in the storage portion 44. In a state where the water discharge head 14 is stored in the storage portion 44, the water discharge head 14 is attracted and held on the lower surface of the horizontal portion of the metal structural plate 12a by the magnetism of the two built-in holding magnets 42. Yes. Therefore, the holding magnet 42 and the metal structural plate 12a function as a holding device. The holding magnet 42 provided on the water discharge head 14 applies magnetism to the structural plate 12 a, so that the outer peripheral surface of the water discharge head 14 is moved from the direction different from the connection axis P to the storage portion 44 from the direction different from the connection axis P. Retained. That is, in the present embodiment, the water discharge head 14 is held in the storage portion 42 while the outer peripheral surface thereof is held from the direction perpendicular to the connection axis P.

  As shown in FIG. 5, when the water discharge head 14 is pulled out from the storage portion 44, the water discharge head 14 is pulled downward from the storage portion 44 so as to keep the holding magnet 42 away from the structural plate 12a. The holding by the plate 12 a is released, and the water discharge head 14 is pulled out from the storage portion 44. Thus, by holding the outer peripheral surface of the water discharge head 14 from above or from the side of the water discharge head 14, which is different from the direction of the connection axis P, the water discharge head 14 is moved from the storage portion 44 in the direction of the connection axis P. Can be pulled out generally in a different direction. As a result, even if the front of the water discharge head 14 is covered with the human body detection sensor 22 or the like, the water discharge head 14 can be pulled out without interfering with these. Moreover, since it becomes possible to pull out the water discharge head 14 without providing a big space between the human body detection sensor 22 grade | etc., Ahead of the water discharge head 14, the protrusion dimension of the shelf part 12 can be made small.

  Further, as shown in FIG. 6, when the water discharge head 14 is stored in the storage portion 44, the holding magnet 42 exerts magnetism on the structural plate 12 a so as to lift the water discharge head 14 toward the storage portion 42. (Arrows in FIG. 6). For this reason, the water discharge head 14 is assisted to be pulled up toward the storage portion 44 when approaching the storage portion 44 to a predetermined distance, and the water discharge head 14 is easily guided to a predetermined holding position by this assist. Accordingly, the holding magnet 42 and the structural plate 12a function as assisting means for assisting in housing the water discharge head 14. In the holding position, the water discharge head 14 is supported from the direction in which the outer peripheral surface is perpendicular to the direction of the connection axis P.

  Further, as shown in FIG. 4, the structural plate 12a of the shelf 12 has a part of the horizontal portion cut out, and a magnetic sensor 34 as a holding detection sensor is embedded in the cutout. The magnetic sensor 34 is a Hall element in the present embodiment, and is disposed at a position facing the front holding magnet 42, and detects magnetism from the holding magnet 42. The magnetic sensor 34 detects whether or not the water discharge head 14 is removed from the storage portion 44 based on the magnetism from the holding magnet 40a. Specifically, in a state where the magnetic sensor 34 has not detected the magnetism from the holding magnet 42, the controller 32 determines that the water discharge head 14 has been removed from the storage portion 44.

  Although the magnetic sensor 34 is disposed above the holding magnet 42, it is only necessary to detect that the water discharge head 14 has been removed from the storage unit 44, and is disposed at any position on the shelf 12 or the storage unit 44. can do.

  Next, control of the water solenoid valve 28a and the hot water solenoid valve 28b by the controller will be described with reference to FIG. FIG. 7 is a flowchart of the control executed by the controller 32 and is repeatedly executed while the faucet device 4 is in operation.

  First, in step S1, the faucet device 4 is turned on, and control of the water solenoid valve 28a and the hot water solenoid valve 28b by the controller 32 is started. Next, in step S <b> 2, the controller 32 determines whether or not the water discharge head 14 is removed from the storage unit 44 based on the detection signal from the magnetic sensor 34. Specifically, the controller 32 determines that the water discharge head 14 has been removed from the storage portion 44 when the magnetic sensor 34 has not detected magnetism from the holding magnet 42 incorporated in the water discharge head 14.

  If it is determined in step S2 that the water discharge head 14 has not been removed, the process proceeds to step S3. If it is determined that the water discharge head 14 has been removed from the storage portion 44, the process proceeds to step S7. Proceed to processing. In step S3, based on the human body detection signal from the human body detection sensor 22, the presence or absence of an object to be detected such as a user's finger is determined.

If the object to be detected is not detected in the process of step 3, the process by the controller 32 returns to step S2, and thereafter, until the water discharge head 14 is removed or the object to be detected is detected. The process of S3 is repeated.
If the detected object is detected in the process of step S3, the process of step S4 is executed. In step S <b> 4, the controller 32 sends a signal to the water solenoid valve 28 a and the hot water solenoid valve 28 b, opens them, and discharges hot water from the water discharge head 14. And after performing step S4, the controller 32 moves to the process of step S5, and it is judged whether the to-be-detected object is detected. When the detected object is detected, the process of step S5 is performed again, and the process of step S5 is repeated until the detected object is not detected, and the water discharge state from the water discharge head 14 is maintained.

When the object to be detected is no longer detected in step S5, the process proceeds from step S5 to step S6, and the controller 32 sends a signal to the water electromagnetic valve 28a and the hot water electromagnetic valve 28b to close them. The water discharge from the water discharge head 14 is stopped.
When step S6 is completed, the process in controller 32 returns to step S2.

  On the other hand, if it is determined in step S2 that the water discharge head 14 has been removed from the storage portion 44, the processing in the controller 32 proceeds to step S7. In step S <b> 7, the controller 32 stops the human body detection sensor 22 and ignores the signal from the human body detection sensor 22.

  That is, when the magnetic sensor 34 detects that the water discharge head 14 has been removed from the storage portion 44, the controller 32 uses the water solenoid valve 28 a and the hot water solenoid valve based on the detection by the human body detection sensor 22. 28b is not opened or closed.

  Next, in step S <b> 8, the controller 32 determines whether or not the user has operated the touch switch 18 based on a signal from the touch switch 18. In step S8, when there is no operation by the user, the controller 32 returns to the process of step S2. Thereafter, the process of steps S 2 → S 7 → S 8 → S 2 is repeated until the user operates the touch switch 18 or attaches the water discharge head 14 to the storage unit 44.

  If the operation by the user is confirmed in the process of step S8, the process of step S9 is executed. In step S <b> 9, the controller 32 sends signals to the water electromagnetic valve 28 a and the hot water electromagnetic valve 28 b, opens them, and discharges hot water from the water discharge head 14. Next, the controller 32 proceeds to the process of step S10, and it is determined whether or not the user has operated the touch switch 18. In step S10, when the touch switch 18 is not operated, the process of step S10 is executed again. Thereafter, the process of step S10 is repeated until the user operates the touch switch 18, and the hot water is discharged. Repeated.

  Next, when the operation of the touch switch 18 is detected, the controller 32 proceeds to the processing from step S10 to step S11, and sends a signal to the water solenoid valve 28a and the hot water solenoid valve 28b to close them. The water discharge from the water discharge head 14 is stopped. When the process of step S11 ends, the process of the flowchart returns to step S2.

Below, the effect | action in the vanity 1 by embodiment of this invention mentioned above is demonstrated.
First, according to the bathroom vanity 1 according to the embodiment of the present invention, the water discharge head 14 of the faucet device 4 has an outer peripheral surface formed around the connection axis P from which the flexible hose 36 extends, and includes a storage portion. In the state accommodated in 44, the outer peripheral surface is held by the holding magnet 42 and the metal structural plate 12 a from the direction perpendicular to the connection axis P. For this reason, when pulling out the water discharge head 14 from the storage part 44 of the shelf 12, it is not necessary to pull out the water discharge head 14 in the direction of the connection axis P and release the holding by the holding magnet 42 and the structural plate 12a. Improved and easy to use.

  Moreover, since the outer peripheral surface of the water discharge head 14 is held from the direction perpendicular to the connection axis P, the water discharge head 14 can be pulled out in a direction different from the connection axis P when being removed. As a result, a large space for drawing out from the holding position in the direction of the connection axis P is not required, and the human body detection sensor 22 and the like can be provided adjacent to the front of the water discharge head 14 (FIG. 4). Moreover, it is not necessary to enlarge the accommodating part 44 ahead by this, the protrusion dimension of the shelf part 12 can be suppressed, and design property is good. Furthermore, since the above-mentioned dimension of the shelf portion 12 can be suppressed, a wide cleaning area of the bowl 2 that can be visually observed by the user for cleaning can be ensured, and the convenience of the user is good.

  Further, according to the bathroom vanity 1 according to the embodiment of the present invention, the holding magnet 42 magnetizes the structural plate 12a so that the water discharge head 14 is pulled up toward the storage portion 44 when the water discharge head 14 is brought close to a predetermined distance. It is configured to work and assist. Thus, when the water discharge head 14 is brought close to a predetermined distance, the water discharge head 14 is pulled up to the storage portion 44 and guided to a predetermined holding position, and the outer peripheral surface thereof is supported by the holding magnet 42 from the direction perpendicular to the connection axis P. The Therefore, the storage property is improved and the usability can be improved.

  Further, according to the vanity table 1 according to the embodiment of the present invention, the controller 32 detects the human body detection sensor 22 when the magnetic sensor 34 detects that the water discharge head 14 is removed from the storage unit 44. The water solenoid valve 28a and the hot water solenoid valve 28b are not opened or closed based on this detection (step S7 in FIG. 7). Thereby, in the state where the water discharge head 14 is pulled out from the storage portion 44, the controller 32 controls the opening and closing of the water solenoid valve 28a and the hot water solenoid valve 28b based only on the operation of the touch switch 18 (FIG. 7 and subsequent steps S8), it is possible to prevent water discharge at a timing not intended by the user. Thereby, it is possible to prevent water from being accidentally discharged to the outside of the bowl 2 and to improve the user-friendliness.

  Further, according to the bathroom vanity 1 according to the embodiment of the present invention, the holding magnet 42 and the metal structural plate 12a constitute a holding device, and the magnetic sensor 34 is configured to generate magnetism from the holding magnet 42. Based on this, it is detected whether or not the water discharge head 14 is removed from the storage unit 44. For this reason, the holding magnet 42 of the holding device can also be used as a magnet for detection by the magnetic sensor 34, and it is not necessary to provide a new magnet to detect the state in which the water discharge head 14 is pulled out from the storage portion 42. Can be configured.
