Description

  The present invention relates to a faucet device, and more particularly to a faucet device capable of adjusting the flow rate of hot water discharged.

  At present, a faucet device capable of adjusting the flow rate of hot water discharged as described in Japanese Patent Application Laid-Open No. 2006-144329 (Patent Document 1) is widely used. In the automatic water faucet (water faucet device) described in Patent Document 1, the supplied hot water and water are respectively sent to the mixing valve via the electromagnetic valve, and the mixing ratio of the hot water and water is adjusted in this mixing valve. In addition, the flow rate of hot water discharged from the water outlet is set.

  In such a faucet device, if the flow rate of the water discharged from the water outlet is set in advance by operating the flow control operation part of the mixing valve, the user only holds his / her finger near the water outlet during use. Thus, water discharge can be performed at a preset flow rate, which is convenient for the user. Moreover, by switching the mixing valve (flow rate adjusting valve) to the water stop state, water is not accidentally discharged from the water outlet at the time of cleaning or the like, and user convenience is good. Moreover, when the electromagnetic valve (discharge water valve) is damaged, water discharge from the water discharge port can be stopped urgently.

  The bowl 2 is a generally rectangular bowl arranged to receive hot water discharged from the water discharge port 22 of the water faucet device 4, and a drain port (not shown) is provided on the bottom surface thereof.

  The faucet device 4 is attached to a wall surface 10 that rises from the bowl 2, and a water discharge port 22 that discharges hot water from the lower surface toward the bowl 2 is formed. The detailed function and structure of the faucet device 4 will be described later.

The lower cabinet 6 is a cabinet that is disposed below the bowl 2 and supports the bowl 2, and is provided with two stages of drawers. Further, inside the lower cabinet 6 are housed devices such as a solenoid valve for switching tap water discharge and stop. Details of the equipment stored in the lower cabinet 6 will be described later.
The upper cabinet 8 is a thin cabinet provided on the wall surface 10 above the faucet device 4, and a mirror is attached to the front surface thereof.

Next, with reference to FIG.2 and FIG.3, the basic structure of the faucet device 4 with which the vanity 1 is equipped is demonstrated.
As shown in FIG. 2, the faucet device 4 includes a shelf portion 12, a water discharge portion 14, a human body detection sensor 16, and an operation handle 20.

  The shelf 12 is formed in a rectangular parallelepiped shape that protrudes forward from the wall surface 10, and the upper surface thereof is formed in a flat shape so that small items can be placed thereon. Therefore, for example, when the face is washed, the user can perform a so-called “slow placement operation” by placing small items such as glasses and cosmetics using the upper surface of the shelf portion 12, which is convenient for the user.

  The water discharger 14 is disposed on the lower surface of the shelf 12. This water discharge part 14 is a faucet device main body, and is formed with a water discharge port 22 for discharging hot water used for washing face, hand washing and the like toward the bowl 2.

  The human body detection sensor 16 is provided on the lower surface of the front end portion of the shelf portion 12 and is configured to detect the approach of a detection object such as a finger to the water discharge portion 14. Automatic water discharge can be performed based on the presence or absence of the object to be detected below. In the first embodiment, the human body detection sensor 16 is an infrared sensor, and is configured to detect an infrared ray reflected by a finger or the like approaching the water discharge unit 14 and detect the approach of the finger or the like. ing. As the proximity sensor, any non-contact type sensor such as an infrared type or a microwave type can be used. In the first embodiment, the human body detection sensor 16 functions as a spout water operation means.

The operation handle 20 is a lever handle that protrudes downward from the lower surface of the shelf 12. The operation handle 20 is connected to a flow control / temperature control valve 24 built in the shelf 12. The operation handle 20 is a flow control operation unit, and can adjust the flow rate of hot water discharged from the water discharge unit 14 by rotating in the front-rear direction and can reduce the flow rate to stop water.
The operation handle 20 can adjust the temperature of the hot water by rotating in the left-right direction.
Note that the operation handle 20 is configured such that the movement of the operation handle 20 is restricted when the flow rate is reduced to the water stoppage. The detailed structure of the operation handle 20 will be described later.

Next, with reference to FIG. 3, the water supply flow path in the vanity 1 by 1st Embodiment of this invention is demonstrated.
As shown in FIG. 3, a water supply channel from a water supply source (not shown) to the water discharge port 22 of the water discharge unit 14 includes a water supply pipe 26 a, a hot water supply pipe 26 b, a stop cock 28 a, a stop cock 28 b, A solenoid valve 30a, a hot water solenoid valve 30b, and a flow control / temperature control valve 24 are provided.

  Specifically, the water supply system of the water supply channel includes, in order from the upstream side, a water supply pipe 26a for supplying tap water from a water supply source, a stop cock 28a for blocking tap water, And a water electromagnetic valve 30a for switching between discharging and stopping from the section 14. Similarly, the hot water supply system of the water supply flow path includes, in order from the upstream side, a hot water supply pipe 26b for supplying hot water from a water heater (not shown) as a water supply source, and a water stop cock 28b for shutting off the hot water. And a hot water solenoid valve 30b for switching between discharge and stop of hot water from the water discharge section 14. In the first embodiment, the water solenoid valve 30a and the hot water solenoid valve 30b function as discharge water valves.

The water and hot water respectively supplied through these water supply system and hot water supply system pass through the flow control / temperature control valve 24 and are discharged from the water discharge port 22 of the water discharge unit 14.
Therefore, in the first embodiment, hot water passes from the water supply source to the water discharge port 22 through the water electromagnetic valve 30a or the hot water electromagnetic valve 30b provided in the water supply flow path and the flow / temperature control valve 24. Water is passed through.

  As described above, the flow control / temperature control valve 24 is a so-called “single lever faucet” connected to the operation handle 20. The flow control / temperature control valve 24 can mix hot water and water supplied through the water supply system and the hot water supply system at a predetermined ratio by operating the operation handle 20. The flow control / temperature control valve 24 is a flow rate adjusting valve, and can adjust the flow rate of the mixed hot and cold water by operating the operation handle 20 and can reduce the flow rate to a water stop state. Thus, when the flow control / temperature control valve 24 is throttled to the water stop state, tap water is not discharged from the spout 22 even if the water solenoid valve 30a or the hot water solenoid valve 30b is opened.

  The water solenoid valve 30a and the hot water solenoid valve 30b are configured such that the controller 32 controls the opening and closing of the valve. Further, the human body detection sensor 16 is connected to the controller 32, and the water electromagnetic valve 30 a and the hot water electromagnetic valve 30 b are controlled to open and close based on the presence or absence of the detected object detected by the human body detection sensor 16.

  In the first embodiment, the controller 32 includes a microprocessor, a memory, an interface circuit, a drive circuit for an electromagnetic valve, software for operating these, and the like (not shown). The controller 32 is operated by electric power supplied from an AC power source (not shown).

Next, with reference to FIG.4 and FIG.5 newly, the detail of the flow control / temperature control of the flow control / temperature control valve 24 by the operation handle 20 of 1st Embodiment of this invention is demonstrated.
FIG. 4 is a side view of the operation handle connected to the flow control / temperature control valve in the first embodiment of the present invention. FIG. 5 is a front view of the operation handle connected to the flow control / temperature control valve in the first embodiment of the present invention.

As shown in FIGS. 4 and 5, the flow control / temperature control valve 24 includes a valve case 34 and a valve lever 36. An operation handle 20 is attached to the valve lever 36.
The valve case 34 is a substantially cylindrical case, and a fixed valve body (not shown) and a movable valve body (not shown) sliding on the fixed valve body are provided inside the valve case. Has been placed. The flow control / temperature control valve 24 is a so-called single that can adjust the mixing ratio of supplied hot water and water and the flow rate of hot water to flow out by sliding the movable valve body relative to the fixed valve body. It is a lever valve.

  The valve lever 36 is a rod-like member disposed so as to protrude forward from the valve case 34, and a built-in movable valve body (not shown) can be slid by rotating the valve lever 36. . Further, the valve lever 36 is connected to the operation handle 20, and the temperature and flow rate of the flowing hot water can be adjusted by sliding the movable valve body in conjunction with the movement of the operation handle 20.

  The operation handle 20 is an inverted L-shaped member bent downward, and includes a short side portion and a plate-like long side portion formed so as to extend downward from the tip of the short side portion. A valve lever 36 of the flow control / temperature control valve 24 is connected to the rear end of the short side.

  As shown in FIG. 4, the operation handle 20 can be turned up and down around the operation axis A1 extending in the direction perpendicular to the paper surface of FIG. 4 by the user's operation. The flow rate can be adjusted. That is, in the state where the operation handle 20 is at the position shown in FIG. 4, the flow rate of discharged hot water is minimal, and the operation handle 20 is rotated forward from this position (the tip of the operation handle 20 is raised upward). As a result, the flow rate increases, and the flow rate can be adjusted. Further, when the operation handle 20 is slightly rotated backward from the state shown in FIG. 4 (the tip of the operation handle 20 is lowered), the water is stopped. In this way, the operation handle 20 can rotate between the flow rate adjustment area R2 above the position shown in FIG. 4 and the water stop area R1 below the position shown in FIG.

  Specifically, the operation handle 20 can be rotated up to 13 degrees upward from the position shown in FIG. 4 and up to 10 degrees downward. Thus, the range of 10 degrees downward from the position shown in FIG. 4 is the water stop area R1, and the flow control / temperature control valve 24 is in a water stop state in this area. Further, the range up to 13 degrees upward from the position shown in FIG. 4 is the flow rate adjustment area R2, and the flow control / temperature control valve 24 is in the flow rate adjustment state, and rotates upward from the position shown in FIG. The larger the angle, the larger the flow rate of discharged hot water.

  On the other hand, as shown in FIG. 5, the operation handle 20 can be rotated within a predetermined range in the left-right direction around the operation axis A2 in the direction perpendicular to the paper surface of FIG. Accordingly, the temperature of hot water discharged from the water outlet 22 can be adjusted.

  Specifically, the operation handle 20 can be rotated in the range of 100 degrees in the left-right direction around the operation axis A2, and the temperature of the hot water discharged from the water outlet 22 is controlled by rotating in the right direction. It becomes low temperature, and the temperature of the hot water discharged from the spout 22 becomes high by turning leftward.

Next, with reference to FIG. 4, the movement restriction | limiting of rotation of the operation handle 20 is demonstrated. The movement restriction of the operation handle 20 is realized by an operation restriction mechanism 40 provided on the operation handle 20.
As shown in FIG. 4, the operation restriction mechanism 40 is disposed on the lower surface of the short side portion of the operation handle 20. Further, the operation restricting mechanism 40 is invisible to the user located in front due to the long side portion of the operation handle 20. The operation restriction mechanism 40 includes a base portion 42, a pressing portion 44, and a stopper 46.

The base portion 42 is a columnar member that protrudes downward from the lower surface of the short side portion of the operation handle 20.
The pressing portion 44 is a cylindrical member that covers the circumferential direction and the lower side of the base portion 42. A spring (not shown) that urges the pressing portion 44 in the axial direction of the base portion 42 is provided between the base portion 42 and the pressing portion 44, and the pressing portion 44 is a base portion that is pressed by a user. It moves in the axial direction of 42, and when the pressure from the user is lost, it returns to its original position by the bias of the spring.

  The stopper 46 is a protrusion formed to protrude rearward from the outer peripheral surface of the pressing portion 44. The stopper 46 moves in the axial direction of the base portion 42 together with the pressing portion 44 when the user presses the pressing portion 44.

  On the other hand, the valve case 34 is provided with a stopper receiver 38. The stopper receiver 38 includes a concave ring-shaped portion 38 a attached to the front end surface of the valve case 34, and a protrusion 38 b extending from the ring-shaped portion 38 a toward the operation restricting mechanism 40. Further, the stopper receiver 38 is configured to rotate in accordance with the rotation of the operation handle 20 in the left-right direction. For this reason, the protrusion 38 b of the stopper receiver 38 is always at a position facing the stopper 46 of the operation restriction mechanism 40.

  Therefore, when the operation handle 20 is rotated backward (the tip of the operation handle 20 is lowered) in order to reduce the discharge flow rate, the stopper 46 and the stopper of the operation restriction mechanism 40 are stopped at the temporary stop position shown in FIG. The protrusion 38b of the receiver 38 comes into contact, and the operation handle 20 can no longer be rotated downward. That is, when the operation handle 20 is at the temporary stop position (position shown in FIG. 4) that is the boundary between the flow rate adjustment area R2 and the water stop area R1, the stopper 46 and the tip of the protrusion 38b come into contact with each other. As a result, when the operation handle 20 rotates from the flow rate adjustment area R2 to the water stop area R1, the operation handle 20 is restricted in movement so that the rotation is temporarily stopped at the temporary stop position.

  When the operation handle 20 is rotated from the flow rate adjustment area R2 to the water stop area R1, the operation handle 20 is rotated backward while pressing the pressing portion 44 of the operation restriction mechanism 40. When the pressing portion 44 is pressed and slides in the axial direction of the base portion 42, the stopper 46 also slides in the axial direction of the base portion 42 together with the pressing portion 44, so that the stopper 46 does not come into contact with the protruding portion 38 b of the stopper receiver 38. As a result, the operating handle 20 can be rotated beyond the temporary stop position shown in FIG. 4 to the water stop area R1 as indicated by an imaginary line in FIG. In the first embodiment, the pressing unit 44 functions as a release operation unit.

  Thus, the operation handle 20 cannot be rotated to the water stop area R1 unless an operation different from a normal operation for adjusting the flow rate (an operation for pressing the pressing portion 44) is not performed. Thereby, when a user does not know the operation method of a faucet device, it can control moving a flow control operation part to water stop area R1 accidentally.

  In a state where the operation handle 20 is in the water stop area R1, the stopper 46 is engaged with the upper surface of the protrusion 38b, and the pressing portion 44 remains pushed in the axial direction of the base portion 42. When the operation handle 20 is moved from the water stop area R1 to the flow rate adjustment area R2, the stopper 46 and the protrusion 38b are automatically disengaged, and the pressing part 44 is moved to its original position by the biasing force of a spring (not shown). Return to. As a result, when moving from the water stop area R1 to the flow rate adjustment area R2, the operation handle 20 smoothly rotates to the flow rate adjustment area R2 without being temporarily stopped at the pause position shown in FIG. Can do. That is, when returning the operation handle 20 from the water stop area R1 to the flow rate adjustment area R2, the user can smoothly perform the rotation by a normal operation, which is convenient.

  Further, when the operation handle 20 rotates in the flow rate adjustment area R2 beyond the temporary stop position, the pressing portion 44 is returned to the original position by the spring, and accordingly, the stopper 46 is also returned to the original position. Therefore, when the user next turns the operation handle 20 from the flow rate adjustment area R2 to the water stop area R1, the stopper 46 and the tip of the projection 38b come into contact with each other, and the operation handle 20 is rotated at the temporary stop position. Movement is restricted.

Next, the operation of the faucet device 4 according to the first embodiment of the present invention described above will be described.
First, according to the faucet device 4 according to the first embodiment of the present invention, based on the user's operation, the flow adjustment / temperature adjustment valve is changed from the flow adjustment area R2 where the flow adjustment / temperature adjustment valve 24 is in the flow adjustment state. An operation handle 20 that can be turned to a water stop area R1 in which the water stop state 24 is stopped, and an operation restriction that temporarily stops the operation handle 20 when the operation handle 20 is turned from the flow rate adjustment area R2 to the water stop area R1. A mechanism 40 is provided. For this reason, when the user does not know the operation method of the faucet device 4, the operation handle 20 is erroneously moved to the water stop area R1, and is used for the human body detection sensor 16 to discharge water at the next use. Even if it detects a person's finger etc., the inconvenience that water discharge is not made can be eliminated.

  Further, when the operation handle 20 moves from the flow rate adjustment area R2 to the water stop area R1, the movement of the operation handle 20 is restricted so that the operation by the user is temporarily stopped. It is possible to make it aware that the regulating / temperature regulating valve 24 has been throttled to the water stop state. For this reason, it is possible to remember to return the operation handle 20 from the water stop area R1 to the flow rate adjustment area R2 after the flow control / temperature control valve 24 is used in the water stop state.

  As a result, the flow control / temperature control valve 24 is in a water-stopped state after use, and avoids the problem that water is not discharged even if the next user uses the human body detection sensor 16 to detect the user's fingers or the like. It is possible to improve the usability of the user.

  Further, according to the faucet device 4 according to the first embodiment of the present invention, the operation restriction mechanism 40 is configured so that the movement restriction is released by an operation different from the normal operation when the flow rate is adjusted by the operation handle 20. The operation handle 20 can be moved to the water stop area R1 by the release of the movement restriction. For this reason, only a user who intends to release the movement restriction by an operation different from the normal operation when adjusting the flow rate with the operation handle 20 releases the movement restriction and moves the operation handle 20 to the water stop area R1. I can't. Therefore, when the user does not know the operation method of the faucet device 4, it is possible to prevent the movement control from being canceled by mistake and moving the operation handle 20 to the water stop area R1.

  Further, according to the faucet device 4 according to the first embodiment of the present invention, the operation restriction mechanism 40 has the pressing portion 44 for releasing the movement restriction, and the movement restriction is released by operating the pressing portion 44. Therefore, the operation handle 20 is moved to the water stop area R1 only when the user recognizes the operation method of the faucet device 4 and intends to release the movement restriction. In the case where the user does not know the operation method of the faucet device 4, it is possible to further prevent the movement restriction from being erroneously canceled and the operation handle 20 to be moved to the water stop area R1.

  In addition, when the operation handle 20 moves from the flow rate adjustment area R2 to the water stop area R1, the movement restriction is released by the operation of the pressing portion 44 by the user. It can be made aware that the flow control / temperature control valve 24 has been throttled to the water stop state. For this reason, it is possible to remember to return the operation handle 20 from the water stop area R1 to the flow rate adjustment area R2 after the flow control / temperature control valve 24 is used in the water stop state.

Further, according to the faucet device 4 according to the first embodiment of the present invention, the operation restricting mechanism 40 rotates when the operation handle 20 is rotated from the water stop area R1 to the flow rate adjustment area R2. Since it is configured so as not to be restricted, the user can smoothly rotate the operation handle 20 from the water stop area R1 to the flow rate adjustment area R2 by a normal operation. Good.
In addition, since the load due to the temporary stop of the operation handle 20 can be reduced, the durability of the operation handle 20 can be improved.

  Moreover, according to the faucet device 4 according to the first embodiment of the present invention, the operation handle 20 is a lever handle that is rotated by a user, and the pressing portion 44 is provided on the back surface of the lever handle. Therefore, the pressing part 44 is difficult to visually recognize from the user, and when the user does not know the operation method of the faucet device 4, the movement restriction is erroneously canceled and the operation handle 20 is moved to the water stop area R1. Can be suppressed.

  Further, since the operation handle 20 is provided with the pressing portion 44, for the user who wants to move the operation handle 20 to the water stop area R1, the movement restriction is released and the operation handle 20 is moved to the water stop area R1. Easy and convenient to use.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a side view of the operation handle in the second embodiment of the present invention. In this 2nd Embodiment, the same code | symbol is attached | subjected to the same part as 1st Embodiment mentioned above, and those description is abbreviate | omitted.

  As shown in FIG. 6, the faucet device according to the second embodiment of the present invention is provided with an operation handle 50. The operation handle 50 includes an operation restricting mechanism 52 for restricting movement thereof, and a release operation portion. An operation button 56 is provided.

  The operation restriction mechanism 52 is disposed on the lower surface of the short side portion of the operation handle 50. The operation restriction mechanism 52 includes a base 53, a moving member 54, and a stopper 46. The moving member 54 is a cylindrical member that covers the circumferential direction of the base 53. A spring (not shown) that urges the moving member 54 in the axial direction of the base 53 is provided between the base 53 and the moving member 54. The stopper 46 is a protrusion formed to protrude rearward from the moving member 54. The stopper 46 comes into contact with the protrusion 38b of the stopper receiver 38 when the operation handle 50 is positioned at the temporary stop position shown in FIG. 6 which is the boundary between the flow rate adjustment area R2 and the water stop area R1. The rotation of the is regulated.

  The operation button 56 is a cylindrical button and is disposed on the front surface of the operation handle 50. The operation button 56 is not covered with the shelf 12 and is always visible to the user. The operation button 56 is configured to protrude from a position indicated by a solid line in FIG. 6 to a position indicated by an imaginary line once pressed. The operation button 56 is connected to the moving member 54 by a link mechanism (not shown) inside the operation handle 50. As a result, when the operation button 56 is operated and protrudes to the position indicated by the imaginary line in FIG. 6, the moving member 54 slides in conjunction with it, and the stopper 46 also slides to the position indicated by the imaginary line in FIG. As a result, the stopper 46 moves to a position where it does not come into contact with the protrusion 38b of the stopper receiver 38, and the operation handle 50 becomes rotatable to the water stop area R1. That is, the movement restriction of the operation handle 50 is released.

  The operation button 56 has a colored surface 56a in which the rear end of the outer peripheral surface is colored red. In a state where the operation button 56 indicated by a solid line in FIG. 6 is pushed (in this state, the rotation to the water stop area R1 is restricted), the colored surface 56a is retracted into the operation handle 50 and is not visible. . Further, when the operation button 56 is operated and protrudes to a position indicated by an imaginary line in FIG. 6 (in this state, it is possible to rotate to the water stop area R1), the colored surface 56a is inside the operation handle 20. It moves forward and is exposed.

  Therefore, it can be confirmed whether or not the colored surface is exposed when the operation button 56 is pressed and the movement restriction is released. Thus, the colored surface 56a of the operation button 56 functions as a recognition means for recognizing that the operation handle 50 is in the water stop area.

  Accordingly, the user can easily recognize that the operation handle 50 is in the water stop area R1. Moreover, without providing the coloring surface 56a which is a recognition means specially, it can be used also as the operation button 56 which is a cancellation | release operation part, and it can be set as a simple structure.

  As mentioned above, although preferable embodiment of this invention was described, a various change can be added to embodiment mentioned above. In particular, in the first and second embodiments described above, the faucet device of the present invention is applied to a bathroom vanity, but the water of the present invention can be applied to any device such as a faucet device for a kitchen or a bathroom. A plug device can be applied.

  In the first embodiment of the present invention described above, the flow / temperature control valve 24, which is a flow rate adjustment valve, is provided downstream of the water solenoid valve 30a and the hot water solenoid valve 30b. However, the present invention can also be applied to a faucet device in which a discharge valve is connected to the downstream side of the flow rate adjustment valve.

  Furthermore, in the first embodiment described above, the present invention is applied to an automatic faucet, and the water solenoid valve 30a and hot water solenoid valve 30b, which are water discharge valves, are provided by the human body detection sensor 16 which is water discharge operation means. The valve was opened when the user's fingers were detected. However, the present invention can also be applied to a manual faucet device in which the user manually operates the discharge valve. In this case, a button, a lever, a knob and the like for the user to open and close the water stop valve function as the water stop operation means.

  In the first embodiment described above, the operation handle 20 which is a flow adjustment operation unit is configured to be rotatable, and the water stop area R1 and the flow rate adjustment area R2 are divided within a predetermined angle range. The flow control operation unit can be configured by a possible knob or the like. In this case, the water stop area R1 and the flow rate adjustment area R2 are divided within a predetermined translational movement range.

  Furthermore, in 2nd Embodiment mentioned above, although the recognition means to recognize that the operation handle 50 exists in a still water stop area was comprised by the colored surface 56a provided in the operation button 56, a recognition means is comprised by another structure. Can be configured. For example, the recognition means can be configured by a warning lamp that is turned on when the flow control unit is in the water stop area, or a speaker that emits sound or sound.

  In the first embodiment described above, in a state where the operation handle 20 is located at the temporary stop position, the stopper 46 of the operation restriction mechanism 40 and the protrusion 38b of the stopper receiver 38 come into contact with each other, and the operation handle 20 is placed in the water stop area R1. It was in a state where it could not be rotated. However, the flow control operation unit may be temporarily stopped by another configuration. For example, when the flow adjustment operation unit is moved or rotated from the water stop area R1 to the flow rate adjustment area R2, an operation restriction mechanism is configured so that a very large operation force is required. Can also be paused.
