Description

[Technical field]

[0001] The present invention relates to a water faucet device. [Background technology]

[0002] A touchless faucet device is known that combines a first human body detection sensor whose sensing area faces the front direction of the spout with a second human body detection sensor adjacent to the first human body detection sensor whose sensing area also faces the front direction of the spout (Patent Document 1). For example, the first human body detection sensor is used to control the discharge and stop of raw water, and the second human body detection sensor is used to control the discharge and stop of purified water.

[0003] Also known is a touchless faucet device that combines a pair of first human body detection sensors whose sensing areas are oriented to the left and right of the spout and a second human body detection sensor whose sensing area is oriented downward of the spout (Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2007-154512 A [Patent Document 2] JP 2012-127155 A Summary of the Invention [Problem to be solved by the invention]

[0005] In commercializing a touchless faucet device capable of independently performing two types of water discharge and stop operations, the present inventors have repeatedly studied the optimization of the layout of the sensing area of ​​the human body detection sensor.

[0006] In the layout described in Patent Document 1, the sensing areas of both human body detection sensors are directed directly in front of the spout, making it difficult to distinguish between the two, meaning that it is easy to erroneously operate the unintended water discharge stop operation.

[0007] In the layout described in Patent Document 2, the sensing area of ​​the second human body detection sensor is directed downward from the spout, which makes it easy for accidental operation to occur, such as unintentionally turning the water on and off, when performing tasks such as washing dishes.

[0008] The present invention was invented based on the above findings. The object of the present invention is to provide a touchless faucet device that can independently perform two types of water discharge and stop operations and is less likely to cause operational errors. [Means for solving the problem]

[0009] The present invention is a faucet device comprising a first object detection sensor capable of detecting objects without contact, a second object detection sensor capable of detecting objects without contact, a spout to which the first object detection sensor and the second object detection sensor are attached, and a control device that controls the stopping and spouting of water from the spout, wherein the control device switches between a first mode of water spouting and water stoppage based on the detection state by the first object detection sensor, and switches between a second mode of water spouting and water stoppage different from the first mode based on the detection state by the second object detection sensor, wherein the first object detection sensor is positioned so that its detection area is formed toward one of the left and right sides from the spout, and the second object detection sensor is positioned so that its detection area is formed from the spout toward the upper side of the spout and within the area on the other left or right side of the spout.

[0010] According to the present invention, the first object detection sensor is disposed so that its detection area is formed toward one of the left and right sides from the spout, and the second object detection sensor is disposed so that its detection area is formed from the spout toward the upper side of the spout and toward the other of the left and right sides of the spout, so that the detection areas of the first object detection sensor and the second object detection sensor can be reliably distinguished from each other. In other words, erroneous operation in which water discharge / stop control is performed in an unintended mode is unlikely to occur.

[0011] For example, the first object detection sensor is capable of detecting an object by transmitting and receiving a first signal through a first sensor window, the second object detection sensor is capable of detecting an object by transmitting and receiving a second signal through a second sensor window, the first sensor window is arranged on a surface facing one of the left and right sides of the spout, the first signal is transmitted from the first sensor window toward an area on the one side, the second sensor window is arranged on a surface facing the upper side of the spout, the second signal is transmitted from the second sensor window toward an area on the other of the left and right sides of the spout, and the second sensor window is arranged at a lower position than the first sensor window.

[0012] In this case, the first sensor window is arranged on the surface facing one of the left and right sides of the spout, and the first signal is transmitted from the first sensor window toward the area on the one side, and the second sensor window is arranged on the surface facing the upper side of the spout, and the second signal is transmitted from the second sensor window toward the area on the other of the left and right sides of the spout, so that the act of placing a hand over the first sensor window and the act of placing a hand over the second sensor window can be reliably distinguished and detected. In other words, erroneous operation in which water discharge and stop control is performed in an unintended mode is unlikely to occur.

[0013] The second sensor window is preferably disposed at a lower position than the first sensor window.

[0014] In this case, it is easy to adopt a design layout in which the height position of the hand when held over the first sensor window is different from the height position of the hand when held over the second sensor window, making it even less likely that an erroneous operation such as executing water discharge and stop control in an unintended mode will occur.

[0015] For example, the spout has a base end extending in a vertical or approximately vertical direction, and an extension portion disposed above the base end and extending in a horizontal or approximately horizontal direction, the first sensor window being attached to the extension portion, and the second sensor window being attached to the base end.

[0016] This allows the second sensor window to be disposed at a lower position than the first sensor window with a simple configuration.

[0017] It is also preferable that the spout is provided with a protruding portion protruding to the other side, the second sensor window is attached to the protruding portion, and the second signal is transmitted from the second sensor window obliquely toward the upper front side. Here, "forward" refers to a direction perpendicular or substantially perpendicular to the left-right direction, toward the user.

[0018] By providing the protrusion, it becomes easy to arrange the second sensor window at a desired design position. Also, by transmitting the second signal from the second sensor window diagonally forward and upward, when a hand is placed over the second sensor window, water dripping from the hand and wetting the protrusion is prevented.

[0019] In this case, it is further preferable that the protrusion is arranged at the base end so as to protrude toward the other side, a water outlet is provided in the extension, and the second signal is transmitted toward the rear side of the water outlet.

[0020] According to this, the detection area based on the second signal is located behind the area where the water is discharged from the water outlet, so that erroneous operation of unintentionally controlling the water discharge and stopping during operations such as washing dishes is unlikely to occur. In addition, water from the washing operation is effectively prevented from wetting the protruding part.

[0021] It is also preferable that an operating unit for adjusting the water flow rate from the water outlet is arranged on one of the left and right sides of the spout, and the second sensor window is arranged on the other of the left and right sides of the spout.

[0022] This prevents the second object detection sensor from malfunctioning (making a false detection) when operating the operating portion that adjusts the amount of water discharged from the water outlet.

[0023] In addition, the spout has an exterior member, a water discharge head that can be pulled out from the exterior member, a water supply hose inserted into the exterior member and connected to the water discharge head, and a first sensor case that holds the first object detection sensor, and it is preferable that the first sensor case is fixed within the exterior member so that the first object detection sensor is located below the water supply hose.

[0024] By using the first sensor case, it becomes easy to position the first object detection sensor closer to the lower side within the exterior component and the water supply hose closer to the upper side within the exterior component, so even when a pull-out water spout head is used, there is no need to increase the inner diameter of the exterior component.

[0025] In this case, it is preferable that the first sensor case further includes a water intrusion prevention wall portion that slopes downward toward an intrusion water discharge port provided in the spout.

[0026] This allows water that has entered the spout to be more reliably discharged. Effect of the Invention

[0027] According to the present invention, the first object detection sensor is disposed so that its detection area is formed toward one of the left and right sides from the spout, and the second object detection sensor is disposed so that its detection area is formed from the spout toward the upper side of the spout and toward the other of the left and right sides of the spout, so that the detection areas of the first object detection sensor and the second object detection sensor can be reliably distinguished from each other. In other words, erroneous operation in which water discharge / stop control is performed in an unintended mode is unlikely to occur. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings, in which: Fig. 1 is a schematic front view of a water faucet device 1 according to an embodiment of the present invention.

[0030] The faucet device 1 of this embodiment is a hot and cold water mixing faucet that can adjust the flow and temperature of raw water, and can also selectively use purified water instead of raw water (hot and cold water), and is positioned, for example, at the rear (back) of a kitchen sink.

[0031] A hot water inlet 2, a water inlet 3, and a purified water inlet 61 are provided on the lower wall of the kitchen sink, and the hot water inlet 2 is connected to a hot water mixing valve 21 in the base end 10 of the faucet device 1 via a hot water supply solenoid valve 52 and a hot water supply pipe 22, the water inlet 3 is connected to the same hot water mixing valve 21 via a water supply solenoid valve 53 and a water supply pipe 23, and the purified water inlet 61 is connected to the water inlet of the purified water cartridge 63 via a purified water supply solenoid valve 54 and a purified water supply pipe 62.

[0032] The hot and cold water mixing valve 21 is of a known configuration and is capable of controlling (operating) flow and temperature adjustments using a single lever cartridge. Specifically, hot water is supplied through a hot water supply pipe 22, cold water is supplied through a water supply pipe 23, and after being mixed to a desired flow rate and temperature according to the position and attitude of the single lever cartridge, the water is discharged through a water outlet pipe 24 and a water supply hose 25.

[0033] Water supply hose 25 is connected to water outlet pipe 24, and its movement in the space below the kitchen sink is restricted by passing through hose spacer guide 26 fixed to water outlet pipe 24. In addition, a stopper 27 is attached to water supply hose 25 below hose spacer guide 26, which restricts the amount that water supply hose 25 can be pulled out.

[0034] A raw water / purified water branch fitting 65 is provided at the connection between the water outlet pipe 24 and the water supply hose 25 , and is connected to the water outlet of the water purification cartridge 63 via a purified water outlet pipe 64 .

[0035] The spout of the faucet device 1 of this embodiment comprises a substantially "Cross" shaped base end 10 having a right side (one side) protruding portion and a left side (the other side) protruding portion, a flow and temperature adjustment control lever 20 (one example of a flow adjustment control portion) provided on the right side (one side) of the right side (one side) protruding portion of the base end 10, and a rotating portion 30 (including a discharge head 36 described later) provided on the upper surface side of the base end 10 so as to be rotatable relative to the base end 10. The upper portion of the rotating portion 30 is an extension portion 30e that extends horizontally.

[0036] The water faucet device 1 is fixed to the rear side of a kitchen sink at the base end 10. A hot and cold water mixing valve 21 is housed inside a protruding portion on the right side (one side) of the base end 10.

[0037] The hot and cold water mixing valve 21 is a single-lever cartridge valve, and the single lever portion thereof serves as a flow and temperature adjustment control lever 20 (an example of an operation part that adjusts the amount of water discharged from the water outlet).

[0038] (Rotating part 30) A single water outlet 41 for soft water spouting is provided near the tip of the extension part 30e, which is the upper part of the rotating part 30. In addition, multiple water spouting holes 42 for water broom spouting are arranged in a matrix on the base end side of the water outlet 41.

[0039] FIG. 2 is an explanatory diagram showing the first water discharge state (soft water discharge) of the faucet device 1 of this embodiment, and FIG. 3 is an explanatory diagram showing the second water discharge state (water broom water discharge) of the faucet device 1 of this embodiment.

[0040] The first water spouting state (soft water spouting) shown in FIG. 2 and the second water spouting state (water broom spouting) shown in FIG. 3 can be switched between at will by manually rotating the rotary switch 43 at the tip of the extension portion 30e.

[0041] Fig. 4 is an explanatory diagram of the pull-out function of the faucet device 1 of this embodiment. As shown in Fig. 4, the tip side of the extension part 30e of the spout of the faucet device 1 of this embodiment is a water-spouting head 36 that can be pulled out from the exterior member 31 of the rotating part 30. The water supply hose 25 is inserted into the exterior member 31 and connected to the water-spouting head 36.

[0042] (First photoelectric sensor 33) Fig. 5 is a longitudinal cross-sectional view in the front-rear direction near the first sensor case 32 of the water faucet device 1 of this embodiment. As shown in Fig. 5, the first sensor case 32, which holds a first photoelectric sensor 33 (an example of a first object detection sensor), is fixed to an exterior member 31 of the rotating part 30.

[0043] In this embodiment, the first sensor case 32 is fixed within the exterior member 31 so that the first photoelectric sensor 33 is located below the water supply hose 25 (so as to separate the water supply hose 25 and the first photoelectric sensor 33 from each other above and below).

[0044] Further, the first sensor case 32 of this embodiment has a water intrusion prevention wall portion 32w that is inclined downward toward the intrusion water discharge port 31d provided in the exterior member 31 of the rotating portion 30.

[0045] The first photoelectric sensor 33 has a first light-emitting element that emits a first detection light (an example of a first signal) through a first sensor window 33w (see FIGS. 2 and 3), and a first light-receiving element that receives, through the first sensor window 33w, the reflected light of the first detection light emitted by the first light-emitting element. The first light-receiving element is preferably disposed on the rear side of the first light-emitting element.

[0046] The first sensor window 33w is located on a surface facing the right side (one example of the left or right side) of the spout extension portion 30e, and the first detection light is transmitted from the first sensor window 33w toward the right side.

[0047] (Second photoelectric sensor 13) Although detailed illustration is omitted, a second sensor case that holds a second photoelectric sensor 13 (an example of a second object detection sensor) is fixed to the exterior member of the base end portion 10.

[0048] The second photoelectric sensor 13 has a second light-emitting element that emits a second detection light (an example of a second signal) through the second sensor window 13w, and a second light-receiving element that receives, through the second sensor window 13w, the reflected light of the second detection light emitted by the second light-emitting element. The second light-receiving element is preferably disposed on the rear side of the second light-emitting element.

[0049] The second sensor window 13w is positioned on the surface facing upward of the left-side protrusion 10p, which protrudes to the left (an example of the other side of the left or right) at the base end 10 of the spout, and the second detection light is transmitted from the second sensor window 13w diagonally forward and upward (for example, at an angle of 60° with respect to the horizontal plane), toward the rear of the water outlet 41 and the water spray holes 42, and toward the area on the left side of the spout.

[0050] (Water discharge / stop control of faucet device 1) The switching from stopped water discharge to raw water discharge (first mode water discharge / stop control) is controlled by the first photoelectric sensor 33 detecting the user's "waving of hand."

[0051] Specifically, a detection signal from first photoelectric sensor 33 is transmitted to a controller box 55 (an example of a control device) via a harness (not shown), and a predetermined drive signal is transmitted from said controller box 55 to hot water supply solenoid valve 52 and water supply solenoid valve 53 via a harness (not shown) (see FIG. 1). In this embodiment, from the viewpoint of preventing a user from getting burned, the opening of water supply solenoid valve 53 precedes the opening of hot water supply solenoid valve 52 by a predetermined time.

[0052] The switch from raw water discharge to water stop (first mode water discharge / water stop control) may be controlled by the first photoelectric sensor 33 detecting the user's "wave of hand" again, or the water may be automatically stopped after a predetermined time or amount of water discharge.

[0053] The flow and temperature of the raw water to be discharged are controlled by the user manually operating the flow and temperature control lever 20 .

[0054] In addition, soft water spouting (see FIG. 2) and water broom water spouting (FIG. 3) can be arbitrarily switched by manually rotating a rotary switch 43 at the tip of the extension portion 30e.

[0055] On the other hand, the switching from stopped water discharge to purified water discharge (second mode water discharge / stop control) is controlled by the second photoelectric sensor 13 detecting the user's "waving of hand."

[0056] Specifically, the detection signal of the second photoelectric sensor 13 is transmitted to a controller box 55 (an example of a control device) via a harness (not shown), and a predetermined drive signal is transmitted from the controller box 55 to the purified water supply solenoid valve 54 via a harness (not shown) (see Figure 1).

[0057] The switch from purified water discharge to water stop (second mode water discharge / stop control) may be controlled by the second photoelectric sensor 13 detecting the user's "hand wave" again, or the water may be automatically stopped after a predetermined time or amount of water discharge.

[0058] The faucet device 1 of this embodiment does not have a flow rate adjustment function or a temperature adjustment function for the purified water that is discharged.

[0059] However, even during purified water spouting, soft water spouting (see FIG. 2) and water broom water spouting (FIG. 3) can be arbitrarily switched by manually rotating rotary switch 43 at the tip of extension portion 30e.

[0060] Although not shown in the figure, a commercial AC power source is connected to the controller box 55. The harness connecting the first photoelectric sensor 33 and the second photoelectric sensor 13 to the controller box 55 includes a signal line and a power supply line. Similarly, the harness (not shown) connecting the controller box 55 to the hot water supply solenoid valve 52, the cold water supply solenoid valve 53, and the purified water supply solenoid valve 54 also includes a signal line and a power supply line.

[0061] (Action and effect of the faucet device 1) According to the water faucet device 1 of the present embodiment configured as described above, the first sensor window 33w is arranged on the surface facing the right side of the horizontally extending extension 30e of the rotating part 30 of the spout, and the first detection light is transmitted from the first sensor window 33w toward the right side, and the second sensor window 13w is arranged on the surface facing the upper side of the left side protrusion 10p that protrudes to the left side at the base end 10 of the spout, and the second detection light is transmitted from the second sensor window 13w toward the left side area of ​​the spout, so that the act of holding a hand over the first sensor window 33w and the act of holding a hand over the second sensor window 13w can be reliably distinguished and detected. This makes it difficult for an erroneous operation in which the water discharge stop control of the unintended mode is executed to occur.

[0062] Furthermore, according to the faucet device 1 of this embodiment, the second sensor window 13w is positioned lower than the first sensor window 33w. This allows for a design layout in which the height position of the hand when the hand is held over the first sensor window 33w differs from the height position of the hand when the hand is held over the second sensor window 13w, making it even less likely that an erroneous operation such as the water discharge / stop control of an unintended mode will be executed.

[0063] Furthermore, according to the faucet device 1 of this embodiment, the spout has a base end 10 that extends vertically or approximately vertically, and an extension portion 30e (part of rotating portion 30) that is provided above base end 10 and extends horizontally, with first sensor window 33w attached to extension portion 30e and second sensor window 13w attached to base end 10. This allows, with a simple configuration, second sensor window 13w to be positioned lower than first sensor window 33w.

[0064] In addition, according to the water faucet device 1 of this embodiment, a left-side protrusion 10p is provided that protrudes to the left side of the spout, and a second sensor window 13w is disposed on a surface portion facing the upper side of the protrusion 10p, and the second detection light is projected from the second sensor window 13w diagonally forward and upward. By providing the protrusion 10p, it is easy to arrange the second sensor window 13w in a desired design position. In addition, by transmitting the second detection light from the second sensor window 13w diagonally forward and upward, when a hand is held over the second sensor window 13w, water dripping from the hand and wetting the protrusion 10p is prevented.

[0065] Furthermore, according to the faucet device 1 of this embodiment, the protruding portion 10p is provided so as to protrude to the left side at the base end portion 10, the water outlet 41 and the water sprinkler holes 42 are provided at the extension portion 30e, and the second detection light is projected toward the rear side of the water outlet 41 and the water sprinkler holes 42. As a result, the detection area by the second detection light is located rearward of the water outlet area from the water outlet 41 or the water sprinkler holes 42, so that erroneous operation of unintentionally controlling water outlet and water stop during work such as washing dishes is unlikely to occur. In addition, water during washing work is effectively prevented from wetting the protruding portion 10p.

[0066] Furthermore, according to the faucet device 1 of this embodiment, the flow and temperature adjustment lever 20 is disposed on the right side of the spout, and the second sensor window 13w is disposed on the left side of the spout. This prevents the second photoelectric sensor 13 from malfunctioning (false detection) when the flow and temperature adjustment lever 20 is operated.

[0067] Furthermore, according to the faucet device 1 of this embodiment, the spout has an exterior member 31 of the rotating part 30, a water discharge head 36 that can be pulled out from the exterior member 31, a water supply hose 25 inserted into the exterior member 31 and connected to the water discharge head 36, and a first sensor case 32 that holds a first photoelectric sensor 33, and the first sensor case 32 is fixed in the exterior member 31 so that the first photoelectric sensor 33 is located on the lower side of the water supply hose 25. By using such a first sensor case 32, it is easy to position the first photoelectric sensor 33 closer to the lower side in the exterior member 31 and the water supply hose 25 closer to the upper side in the exterior member 31, and even if a pull-out water discharge head 36 is used, there is no need to increase the inner diameter of the exterior member 31.

[0068] Moreover, the first sensor case 32 of this embodiment has a water intrusion prevention wall portion 32w that is inclined downward toward the intrusion water discharge port 31d provided in the exterior member 31 of the rotating part 30 of the spout. This makes it possible to more reliably discharge the intrusion water that has invaded the spout.

[0069] In this embodiment, a photoelectric sensor is used as the object detection sensor, but the object detection sensor may be of another type as long as it can detect an object without contact. For example, a method using electromagnetic waves such as microwaves, a method using a change in capacitance when a human body approaches, or a method using a camera and image recognition can be considered.
