Description

  The present invention relates to an automatic faucet device that controls opening and closing of a water injection valve in a non-contact manner by sensing an object such as a human body, and a faucet control method.

  In a washroom or shower room, an automatic faucet device is widely used that senses the presence of an object such as a human body with a sensor, and controls water for washing, hot water discharge, and water discharge stoppage. For example, an automatic faucet device configured to stop water flow when a user extends his hand toward a faucet serving as a spout in a toilet basin of a toilet, etc. It is well known (for example, see Patent Document 1).

  The specific operation of such an automatic water faucet device is based on the signal from the sensor, as the user senses this by placing a hand in front of the sensor provided near the water outlet such as a faucet. The actuator is operated to open the water injection valve and start water discharge. At this time, the water injection valve is kept open as long as the sensor continues to sense an object such as a hand. When the sensor no longer senses the object, the actuator operates again based on the signal, and closes the water injection valve to stop water discharge. It can be said that the automatic faucet device according to such a configuration is a device assembled with the simplest logic.

When the automatic faucet device configured as described above is compared with a faucet device that manually operates a conventional faucet, the following advantages arise.
1. Water discharge and water discharge stop operation can all be operated in a non-contact manner, and it is hygienic without bothering human hands.
2. When you do not need water, such as when using soap, you can easily stop water discharge by removing your hand from the sensor, and a water-saving effect can be obtained.
3. There is no need to manually adjust the opening of the valve, and an appropriate amount of water can always be obtained.

On the other hand, the following are cited as disadvantages.
1. The sensing distance of the sensor can be selected arbitrarily, but if this is too short, water discharge stops each time the object leaves the sensor, and a groping action is required to sense it again. It ’s not easy to use.
2. On the other hand, when the sensing distance of the sensor becomes long, water discharge continues even when unnecessary, and a wasteful amount of water flows.
3. Especially in the water discharge at the kitchen, it may be bothersome to detect the sensor one by one, the use of such an automatic faucet device will be avoided and will be used, and the water is continuously discharged with the faucet open. The water was wasted.

  As described above, with respect to a simple automatic water faucet device using a single sensor, a device has been proposed in which a plurality of sensors are arranged to improve the drawbacks of using the above-described single sensor (for example, (See “Patent Document 2”.) According to the device described in Patent Document 2, the first sensor that is directed toward the lower region of the water outlet and mainly senses the human hand, and the human body that is directed toward the upper region of the water outlet and mainly senses the human body. A second sensor, and even if the second sensor senses a human body, if the first sensor does not sense a hand, water will not be discharged, and conversely, the first sensor will not sense a hand during water discharge. However, as long as the second sensor senses the human body, it is configured to continue water discharge. By configuring in this way, even if the first sensor no longer senses the hand with any time signature, the water discharge is interrupted each time as when using a single sensor, and the hand is moved again. There is no need to search for water, and it is improved so that water discharge continues while a person is at a certain distance of the faucet device.

  However, there is also a problem with the apparatus according to Patent Document 2. For example, when the user uses soap and water is unnecessary, even if the first sensor no longer senses the hand, the second sensor still senses the human body, so the water discharge does not stop and is wasted. Water will be wasted. The same applies to the case where the user tries to use the kitchen knife without moving the standing position after cooking vegetables and fruits during cooking. At this time, in order to stop water discharge, the user needs to move to a position outside the sensing area of the second sensor and then return to the original standing position to work again. There was a problem in usability.

  In the prior art, in order to further improve the above-described drawbacks, there has been proposed a faucet device that is provided with two modes, an automatic water discharge mode and a continuous water discharge mode, which can be arbitrarily switched (for example, “Patent Document 3”). "reference.). However, this means complicates the device including the control system, such as providing a changeover switch for switching between the two modes, and also requires a changeover switch to be operated by hand, resulting in a sanitary problem. Obtained.

  As described above, the present invention solves the problems of the automatic faucet device and faucet control method in the prior art as described above, and is simple in operation with a simple structure, but also has excellent hygiene and water saving effect. It is an object to provide an automatic faucet device and a faucet control method.

  The present invention is arranged in a direction different from the first sensor arranged to face the front side from the vicinity of the water outlet and the first sensor such as the side or the rear side near the water outlet. The above-described problem is solved by using a second sensor that senses the movement of a human hand and a control device that controls the water injection valve according to the sensing results of both sensors. Includes the following:

  That is, one aspect of the present invention is an automatic water faucet device that is connected to a faucet such as a faucet, and is disposed toward a front surface of the control unit that controls the operation of the entire device, and the faucet. A first sensor configured to sense a user entering a predetermined detection area on the front surface of the water outlet and transmit the detection signal to the control unit; and a substantially side surface or back surface of the water outlet, A second sensor arranged in a different direction from the first sensor, configured to sense a moving body that moves in front of the first sensor without contact and to transmit a detection signal to the control unit; A water injection valve disposed between the water outlet and the water supply pipe on the upstream side thereof, and configured to allow and block the flow of fluid based on a command of the control unit, and the control unit includes 1st, 2nd When detection signals are received from both sensors, a command is sent to the water injection valve to allow the flow of fluid, and when a second detection signal is received from the second sensor, or from the first sensor The present invention relates to an automatic water faucet device configured to transmit a command to the water injection valve so as to cut off a flow of fluid when no signal is received.

  When the water outlet is also connected to the second water supply pipe, the automatic faucet device is further arranged on a substantially side surface or back surface of the water outlet and directed in a different direction from the second sensor, A third sensor configured to sense a moving body moving on its front surface by contact and transmit a detection signal to the control unit; and the water outlet and the second water supply pipe on the upstream side thereof. And a second water injection valve arranged between and configured to allow or block a flow of fluid flowing through the second water supply pipe based on a command of the control unit. In this case, when the control unit receives detection signals from both the first and third sensors, the control unit transmits a command to the second water injection valve to allow the flow of fluid, and the third sensor When the detection signal is received again from the first sensor or when the detection signal is not received from the first sensor, a command is transmitted to the second water injection valve to cut off the flow of the fluid. .

  In any of the above cases, a water storage switch can be further provided in the automatic faucet device. In this case, a timer function is added to the control unit, so that, when the water storage switch is pressed, the control unit has a time set in advance in the timer function after the previous water storage switch is pressed. When the detection signal is received from the second or third sensor before or during the period before the detection signal is received, a command is sent to the second water injection valve to allow the flow of fluid. Can be configured to.

  The automatic faucet device has a pilot lamp that lights while the device is energized, a water injection lamp that lights when the water injection valve is open and water is discharged, and lights when the water storage switch is pressed and water is discharged An optional storage lamp can be provided.

  Another aspect according to the present invention is a faucet control method for controlling the flow of fluid from a water outlet in a non-contact manner, which is disposed toward the front surface of the water outlet and enters a predetermined detection region on the front surface of the water outlet. A first sensor that senses a user is provided, and a second sensor that senses a moving body that is arranged in a different direction from the first sensor of the water outlet and moves on the front surface without contact is provided. When the detection signal is received from both the first and second sensors, the flow of fluid from the water outlet is allowed and when the detection signal is received again from the second sensor, or the first sensor The present invention relates to a faucet control method characterized in that control is performed so as to block a flow of fluid from a water outlet when no detection signal is received from a sensor.

  By implementing the present invention, it is possible to provide an automatic faucet device that has a simple structure, is easy to use, and is hygienic and has a water-saving effect in general homes, schools, hospitals, various nursing homes, and even cooking workshops. It will be a thing.

1 is a perspective view showing an automatic faucet device according to an embodiment of the present invention. It is a plane block diagram of the automatic water faucet device shown in FIG. It is a flowchart which shows operation | movement of the automatic water faucet apparatus shown in FIG. It is a plane block diagram which shows the automatic water tap apparatus which concerns on other embodiment of this invention. It is a flowchart which shows operation | movement of the automatic water faucet apparatus concerning further another embodiment of this invention.

  An automatic faucet device according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view of an automatic faucet device 1 according to the present embodiment, and FIG. In both figures, the automatic faucet device 1 is arranged toward the front of a faucet 11 (hereinafter also referred to as “faucet 11”) that is a faucet in the illustrated example, and senses the user's human body and the like. A sensor (first sensor) 13, a motion sensor (second sensor) 12 that is arranged toward the substantially side surface of the water outlet 11 and senses the movement of a human hand, etc., and a water supply pipe upstream of the water outlet 11. It is comprised from the control unit 15 arrange | positioned at 16 and the water injection valve 14 which opens and closes a water channel, and the automatic faucet device.

  The motion sensor 12 is a sensor that senses and transmits a detection signal each time a moving object passes through the front surface of the sensor. In the present embodiment, the motion sensor 12 is 5 cm on the front surface (side surface toward the faucet 11) of the motion sensor 12. It is configured to sense the passage of moving objects within. For example, a user who faces the faucet 11 passes the front of the motion sensor 12 from the top to the bottom so that the detection signal can be transmitted to the control unit 15 via the motion sensor 12. The moving body to be detected is not limited to a human hand, and for example, a knife held in the hand may be passed during cooking. Since the motion sensor 12 is arranged toward substantially the side of the faucet 11, the user's movement on the front side is not sensed, and can be sensed only by reaching up and down. Is very good.

  Next, the front sensor 13 is arranged substantially in front of the faucet 11, senses the human body of the user approaching the faucet 11, and the like exists as long as the target exists in a predetermined detection area. Then, the “detection ON” signal is continuously transmitted to the control unit 15, and the “detection OFF” signal is also transmitted to the control unit 15 when it goes out of the detection area. In the present embodiment, the detection area is set to cover 80 cm ahead of the faucet 11, but this can be set to a desired distance and area by changing the specifications of the front sensor 13.

  In this embodiment, the water injection valve 14 uses a solenoid valve that operates by energization based on a command from the control unit 15, and this operation is known to those skilled in the art. However, the water injection valve 14 may be of any other type as long as the flow of water or the like flowing through the water supply pipe 16 can be switched between acceptable and blocked by other types of actuators.

  The control unit 15 receives detection signals from the motion sensor 12 and the front sensor 13 by the CPU, and transmits a signal for permitting or blocking necessary water discharge to the water injection valve 14 in accordance with this. In the example shown in FIG. 1, the control unit 15 is further connected to a power switch 17, a pilot lamp 18, and a water injection lamp 19. Of these, the pilot lamp 18 and the water injection lamp 19 are optional.

  The operation of the automatic faucet device 1 according to the present embodiment configured as described above will be described with reference to the flowchart shown in FIG. The operation shown in the figure is also a control flow by the control unit 15. In FIG. 3, when the power source is energized in Step 1, the pilot lamp 18 is turned “ON” in Step 2 and is lit. In Step 3, the water injection valve 14 is “closed”. In a state where the automatic water faucet device 1 is not energized, the water injection valve 14 is always “closed”, and the water injection valve 14 is operated to be “open” only at the time of water discharge.

  Subsequently, when the user approaches the faucet 11, first, the front sensor 13 senses this in step 4 and becomes “ON”, and a detection signal is transmitted to the control unit 15. However, water discharge is not started only by “ON” of the front sensor 13. Subsequently, in step 5, when a person puts his hand in front of the motion sensor 12 (abbreviated as “M sensor” in the flow in the figure), the motion sensor 12 senses this and becomes “ON”, which is also detected. A signal is transmitted to the control unit 15. When both the motion sensor 12 and the front sensor 13 have sensed, the control unit 15 operates the water injection valve 14 to “open” the water injection valve in step 6 and starts water discharge from the faucet 11. At the same time, in step 7, the water injection lamp 19 is turned “ON” and lights up, indicating that the water is being discharged. In this state, the user can perform the necessary operation of washing his / her hands using the flowing water. During this time, even if the user releases his / her hand from the vicinity of the faucet 11, the front sensor 13 is kept “ON” as long as the user stays in the detection area of the front sensor 13, so water discharge continues.

  Next, when the user finishes using the water, or when the user desires to stop the water discharge temporarily, in step 8, the user again places his hand in front of the motion sensor 12 so that the motion sensor 12 A second detection signal is sent to the control unit 15. Also in this case, since the motion sensor 12 senses the contactlessly, the hand being cleaned can be kept in a good sanitary state. In response to the command of the control unit 15 that has input this signal, the flow proceeds to the right and the water injection lamp 19 is turned off in step 9 and turned off. At the same time, the flow returns to the water injection valve “closed” in step 3, and Stop. That is, in this operation, even if the front sensor 13 continues to sense a person in step 4, the detection of the motion sensor 12 by the person's intentional operation in step 8 is given priority and the water discharge stops, so that the person Even if you are standing in front of you, you can prevent wasteful water flow. In addition, since the user can stop water discharge without touching the user just by holding his hand in front of the motion sensor 12 on the spot, the usability is extremely good.

  In this state, since the motion sensor 12 is sensing twice, it returns to the initial state (a state where the first sensing is possible). Therefore, when the user wishes to discharge water again, the motion sensor 12 generates a first detection signal by holding the hand once again on the motion sensor 12 in step 5, so that the water injection valve 14 is again turned on in step 6. Can be opened. The following operations are the same as the previous flow.

  On the other hand, when the motion sensor 12 is not detected for the second time in step 8, the flow proceeds downward and water discharge is continued until “front sensor OFF” is detected in step 10. Therefore, if the user desires, water discharge can be continuously obtained as long as the user continues to stand in the detection area of the front sensor 13 in front of the faucet 11. Next, when the user leaves the detection area of the front sensor 13 and becomes “front sensor OFF” in step 10, this signal is sent to the control unit 15 and switched to “water injection valve closed” in step 11. Then, the water discharge stops, and at the same time, the water injection lamp is turned off at step 12. The operation at this time means that water discharge can be stopped by going out of the detection area of the front sensor 13 without the user having finished the cleaning operation using the motion sensor 12. Even when a person forgets to stop water discharge, water discharge can be stopped in the same manner. If the front sensor 13 is “OFF” in step 10 to stop water discharge, the motion sensor 12 is initialized in step 13. As a result, when the motion sensor 12 next senses the movement of a human hand, this is the first detection in step 5.

  To summarize the above operation, in the automatic faucet device according to the present embodiment, the water injection valve 14 becomes “open” only when there is a detection signal from both the motion sensor 12 and the front sensor 13. Water discharge is performed, and water discharge stops when there is a second detection signal from the motion sensor 12 or when there is an “OFF” detection signal from the front sensor 13.

  The automatic faucet device 1 according to the present embodiment has the following characteristics as compared with the faucet device according to the prior art. That is, with respect to the automatic faucet device having a single sensor described in Patent Document 1, even if the hand is removed from the vicinity of the faucet, the water discharge is not stopped and the usability is improved. For the automatic water faucet device having two sensors described in Patent Document 2, it is possible to stop water discharge based on the detection of one of the two sensors. . For the automatic water faucet device that switches the water discharge mode described in Patent Document 3, the structure is simplified, a complete non-contact operation is realized, and almost the same function can be achieved. In addition, the automatic faucet device according to the present invention as shown in FIGS. 1 and 2 can be retrofitted to an existing faucet with respect to all the examples of the prior art documents. . However, it is of course possible to construct all of these functions as a unit and arrange each unit in a building in advance.

  Next, an automatic faucet device according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 shows an automatic faucet device 1a according to the present embodiment. This automatic faucet device 30 basically has two systems for supplying water to the automatic faucet device shown in the previous embodiment. One is for cold water and the other is for hot water. In the figure, the components shown in the previous embodiment are indicated by the same reference numerals as those for cold water, and the components for hot water that are added to this are shown in the corresponding elements. The symbol is indicated with “a”.

  In FIG. 4, the automatic faucet device 1 a has a second motion sensor 12 a for warm water operation (referred to as “third sensor” in the claims, and is distinguished from the other two sensors). The water injection valve 14a and the water supply pipe 16a are added, and the faucet 11 is configured so that cold water and hot water can be injected from the two pipes 16 and 16a for cold water and hot water. The hot water pipe 16a is connected to a hot water source (not shown). Other elements such as the front sensor 13, the control unit 15, the pilot lamp 18, and the water injection lamp 19 can be used as common elements for cold water and hot water. However, the control unit 15 includes logic that enables the following operation flow. In addition, although it is set as the combination of warm water and cold water here, the combination of two other types of liquid may be sufficient.

  The operation of the automatic faucet device 1a according to this embodiment configured as described above is basically the same as the operation flow of the previous embodiment shown in FIG. That is, when the user wishes to discharge cold water, the user who approaches the faucet 11 and enters the detection area of the front sensor 13 holds his hand over the motion sensor 12 just as in the previous embodiment. Accordingly, cold water is allowed to flow from the faucet 11, and the water discharge can be stopped by again holding the hand in contact with the motion sensor 12 or coming out of the detection area of the front sensor 11. If the user wants hot water, the hot water can be obtained from the faucet 11 by holding the hand over the second motion sensor 12a for hot water displayed on the left side in FIG. . The stopping operation is basically the same as that for the cold water described above.

  When it is desired to obtain cold water and hot water at an appropriate temperature simultaneously, the water injection valves 14 and 14a are opened by holding both hands of the motion sensor 12 and the second motion sensor 12a. And hot water are supplied to the faucet 11 at the same time. The opening degree of the faucet 11 opened in advance serves as a regulator, and the water discharge amount can be kept substantially constant even when both the cold water and hot water injection valves 14 and 14a are opened simultaneously. When it is desired to stop the discharge of either or both of cold water and hot water in the middle of water discharge, it is only necessary to hold the hand in front of the corresponding motion sensors 12 and 12a. Other features are as described in the previous embodiment. In the example shown in FIG. 4, the two systems of the water supply pipes 16 and 16a are used. However, if necessary, the same correspondence is possible even with three or more systems.

  Next, an automatic faucet device according to a third embodiment of the present invention will be described. The automatic faucet device according to the present embodiment is structurally the same as that shown in FIGS. 1, 2, or 4 and is characterized in that a “water storage” function is added as an option. For this reason, a water storage switch 21 shown in FIGS. 1, 2 and 4 (shown by a broken line in FIGS. 2 and 4) and a water storage lamp 22 for displaying a water storage state if necessary are added to the automatic faucet device 1, In addition, a timer function (clock function) (not shown) is added to the control unit 15. The water storage lamp 22 may be incorporated in the water storage switch 21. The same applies to the automatic water discharge switch 17 and the water discharge lamp 19. In the automatic faucet device according to the present embodiment, the user can discharge a certain amount of water from the faucet 11 by operating the water storage switch 21.

  FIG. 5 shows an additional operation flow as an option of the automatic faucet device 1 according to the present embodiment configured as described above. In the figure, the operation from the power-on in step 21 to the water injection valve “closed” in step 23 is the same as steps 1 to 3 in the first embodiment shown in FIG. When the water storage switch 24 is operated in step 24, the water injection valve 14 is opened in step 25. At the same time, the water storage lamp 22 is turned on in step 26 and water discharge from the faucet 11 is started. At this time, in step 27, the clock function is operated and the timer count is started. The set time for the clock function can be arbitrarily set in advance according to the amount of water required. In step 28, when a preset time (for example, 20 seconds) elapses, "timer count is completed", the flow proceeds downward and a signal is sent to the control unit 15, and in step 29, the water injection valve 14 is closed and water discharge is stopped. Stop. At this time, at the same time, in step 30, the water storage lamp is turned off.

  On the other hand, in step 28, even when the water storage is in progress before the time set in advance in the clock function, when the user wishes to stop water discharge, the flow proceeds to the right and proceeds to step 31. When the user holds his hand in front of the motion sensor 12, the motion sensor 12 senses this, and the detection signal is sent to the control unit 15, and the water injection valve 16 is turned on in step 29 based on a command from the control unit 15. It is closed and water discharge can be stopped.

  In the control unit 15, logic is set so that the above operation flow is given priority over the operation flow shown in FIG. 3. That is, regardless of whether the motion sensor 12 or the front sensor 13 senses the water storage operation, the water storage operation is given priority when the water storage switch 21 is pressed. Moreover, in the example shown in FIG. 3, although it has shown in the example using the automatic faucet device 1 of the format (1 system) shown in FIG. 2, in the automatic faucet device 1a of the format (2 systems) shown in FIG. The same applies as an option. At this time, when the water storage button 21 is pressed, whether to open the water injection valve 14 for cold water, the water injection valve 14a for hot water, or both of them simultaneously is determined in advance according to the application. Can be set to If necessary, the water storage switch 21 may be provided separately for cold water and hot water, and the user may select and operate as necessary.

  With the addition of the optional water storage function according to the present embodiment, the user needs to leave a certain amount of water (or hot water) in place just by operating the water storage switch 21 with a slight addition to the automatic faucet device. Can be obtained without being convenient.

  The automatic faucet device according to each embodiment of the present invention has been described above. However, the present invention is directed to an automatic faucet device as shown in each embodiment or a faucet by using a control flow. A method of performing control is also included. That is, in the faucet control method for controlling the flow of fluid from the water outlet in a non-contact manner, first, the faucet control method is arranged to face the front surface of the water outlet and sense a user who has entered a predetermined detection area on the front surface of the water outlet. A first sensor is provided, and a second sensor is provided that is arranged in a different direction from the first sensor of the water outlet and senses a moving body that moves in a non-contact manner on the front surface. When a detection signal is received from both the first and second sensors, the flow of fluid from the water outlet is allowed, and when a detection signal is received again from the second sensor, or the first When no detection signal is received from the sensor, the flow of fluid from the water outlet is controlled to be cut off.

  The application of the automatic faucet device and the faucet control method according to the present invention is not limited to the attachment to the water supply or the like exemplified above. For example, the present invention can be similarly applied to an apparatus for taking out a liquid through a spout, such as brewing, fruit juice, and production of a liquid medicine. The front sensor 13 does not necessarily have to be arranged from the faucet 11 directly in front of the front sensor 13, but it is only necessary to arrange the front sensor 13 toward the front substantially in the direction in which the user approaches. In addition, the motion sensors 12 and 12a are not necessarily disposed directly beside the faucet 11, but may be disposed on the side in a substantially lateral direction away from the direction facing the user, and face the user. It suffices if it is arranged in a direction other than the direction, and if necessary, it may be arranged, for example, directly behind the faucet 11, directly above, or directly below.

  The automatic faucet device and faucet control method according to the present invention are useful in general households, facilities such as schools, kitchens, etc., and can be widely used in each industrial field where the device is manufactured, sold, and used. it can.
