  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described.

  1 to 5 show a first embodiment of the present invention, FIG. 1 is a proximity switch device, (a) is a front view, (b) is a side view, and FIG. 2 is arranged on a construction. FIG. 3 is a block diagram showing a three-wire illumination control system using the proximity switch device, FIG. 4 is a flowchart showing control of the load of the proximity switch device, and FIG. It is explanatory drawing which shows the operation | movement of inversion control of the load on-on by a switch apparatus.

  In FIG. 1, the proximity switch device 1 is formed to have a container body 2 that is formed in a substantially box shape and stores electronic components and the like, and a mounting frame 3 that fixes the container body 2. The container body 2 is provided with a rectangular plate 4 on the front surface, a translucent plate 5 through which infrared radiation and reflected light pass and a translucent plate 6 through which display light passes. Are arranged respectively.

  The proximity switch device 1 is disposed in the building by the mounting frame 3 being screwed to a switch box provided inside the building such as a wall. As shown in FIG. 2, a decorative cover 7 is attached so as to cover the attachment frame 3.

  FIG. 3 shows a three-wire illumination control system 8 using the proximity switch device 1. The illumination control system 8 includes the proximity switch device 1 and the illumination device 9. The illuminating device 9 has an illumination load 10 as a load and an appliance body 11 in which the illumination load 10 is disposed. The illumination load 10 is connected in parallel to the AC power source Vs and is controlled to be turned on / off by the proximity switch device 1.

  The proximity switch device 1 includes a power supply unit 12 connected to an AC power supply Vs, a main control unit 13 that performs various controls, and an infrared LED light emitting unit 15 having an infrared light emitting diode (hereinafter referred to as infrared LED) 14. , An infrared light receiving detector 17 having a phototransistor 16 for receiving infrared light, the translucent plate 6 and the display / SW operation unit 18 disposed therein, and a load control interface (I / F) It has the part 19 and is comprised.

  The power supply unit 12 converts the AC voltage of the AC power supply Vs into a predetermined DC voltage to generate a circuit drive power supply. The main control unit 13 includes a microcomputer that is driven by a circuit drive power supply from the power supply unit 12, and is configured to perform various controls described below. In the software, the microcomputer has a clocking means 13a for measuring the detection time of the reflected infrared rays, which will be described later, and a holding time timer 13b for delaying and turning off (turning off) the illumination load 10.

  The infrared LED light emitting unit 15 radiates infrared rays from the infrared LED 14 at a predetermined timing based on the control of the main control unit 13. For example, infrared rays are radiated from the infrared LED 14 at a time interval of 100 ms for 10 ms. Infrared rays emitted from the infrared LED 14 are emitted forward from the translucent plate 5. The infrared LED 14 and the infrared LED light emitting unit 15 form infrared transmission means.

  The infrared light receiving detector 17 is configured to detect a reflected infrared ray in which an infrared ray emitted from the infrared LED 14 is reflected by an object among infrared rays received by the phototransistor 16. The detection of the reflected infrared light is performed, for example, when the timing of the infrared light emitted from the infrared LED 14 and the timing of the infrared light received by the phototransistor 16 are synchronized, the infrared light received by the phototransistor 16 is transmitted from the infrared LED 14. It is determined that the emitted infrared ray is a reflected infrared ray reflected by an object. The object is usually a human hand or finger held close to the front of the translucent plate 5. Infrared light received by the phototransistor 16 enters from the translucent plate 5. The phototransistor 16 and the infrared light receiving detector 17 form an infrared receiving means for detecting the reflected infrared light. In addition, detection means for detecting the presence or movement of a human body such as a finger or a hand in the vicinity of the translucent plate 5 is formed.

  The reflected infrared light detected by the infrared light receiving detector 17 is timed by a time measuring means (timer) 13 a of the main control portion 13. The time measuring means 13a measures the detection time during which the phototransistor 16 continuously receives the reflected infrared rays at the predetermined timing. When the hand or finger is not held in front of the translucent plate 5 and the continuous reception of the reflected infrared light by the phototransistor 16 is interrupted, the timing of the detection time is terminated. Then, when the infrared light receiving detection unit 17 detects the reflected infrared light again, the detection time of the previous stage is reset, and the continuous detection time of the reflected infrared light is counted again. That is, the time measuring means (timer) 13a constitutes an integrating means, and measures the detection time during which the detecting means continuously detects the presence or movement of a human body such as a finger or a hand.

  The display / SW operation unit 18 displays a control state by the main control unit 13 and has a switch (not shown) for operation input by the user. In the display, the display color passing through the translucent plate 6 and the intensity of transmitted light are changed according to the on / off control of the illumination load 10.

  The load control I / F unit 19 includes a relay, for example, and reversely controls on / off of the illumination load 10 under the control of the main control unit 13. That is, the main control unit 13 controls the load control I / F unit 19 so that the on / off of the illumination load 10 is reversed and controlled according to the detection and detection time of the reflected infrared light of the infrared light reception detection unit 17. The main control unit 13 and the load control I / F unit 19 form load control means for controlling the operation of the illumination load 10 according to the detection time.

  Next, control by the main control unit 13 will be described with reference to FIGS. 4 and 5.

  When the illumination load 10 is in an OFF state, an object such as a hand or a finger is held close to the light transmission plate 5 of the proximity switch device 1 (ON operation), and the infrared light receiving detection unit 17 is connected to the infrared LED 14. When the reflected infrared ray from the infrared object radiated from is detected, the main control unit 13 performs load control I so as to immediately turn on the illumination load 10 regardless of the detection time of the reflected infrared ray timed by the time measuring means 13a. / F unit 19 is controlled. As a result, the illumination load 10 is immediately turned on (lighted) as shown in FIGS. 5 (a) to 5 (c).

  When the illumination load 10 is in an on state (lighted state), an object such as a hand or a finger is held close to the front of the translucent plate 5 of the proximity switch device 1 (OFF operation), and infrared detection is performed. When the unit 17 detects the reflected infrared ray from the infrared object emitted from the infrared LED 14, the main control unit 13 operates the holding time timer 13b. When the holding time timer 13b times up to a predetermined delay time T1, for example, 3 minutes, the main control unit 13 controls the load control I / F unit 19 as shown in FIG. The illumination load 10 is turned off (extinguishes). That is, when the lighting load 10 is turned off (OFF), the lighting load 10 is turned off from the lighting state after the delay time T1 (for example, 3 minutes) has elapsed.

  Then, it is determined whether or not the infrared light receiving detection unit 17 detects the reflected infrared ray over the period of the slow operation in which the holding time timer 13b is operating (FIG. 4, step S1). If the reflected infrared ray is not detected, the holding time timer 13b keeps counting (step S2).

  The holding time timer 13b keeps counting until the reflected infrared ray is detected by the infrared light receiving detector 17 (step S3). When the holding time timer 13b measures a predetermined delay time T1 (for example, 3 minutes) and time is up, the main control unit 13 switches the load control I / F unit 19 as shown in FIG. The lighting load 10 is turned off (extinguished) by controlling (step S4). That is, when the lighting load 10 that is lit is turned off (OFF), the lighting load 10 is turned off after the delay time T1 (for example, 3 minutes) has elapsed.

  When the reflected light is detected by the infrared light receiving detector 17 during the delaying operation of the holding time timer 13b (period in which the illumination load 10 is delayed and turned off) (step S1), the main controller 13 Stops and resets the time of the holding time timer 13b (step S5). As a result, the control to delay (turn off) the illumination load 10 with respect to the load control I / F unit 19 is released. Thereafter, the main control unit 13 performs a measurement process of the continuous detection time of the reflected infrared rays timed by the time measuring means 13a (step S6). Then, it is determined whether the detection time is within a set time T2 (for example, 2 seconds) set or exceeds the set time T2 (step S7).

  If the detection time exceeds the set time T2, the main control unit 13 controls the load control I / F unit 19 to immediately turn off the illumination load 10 as shown in FIG. It is turned off (step S4). That is, the illumination load 10 is immediately turned off from the lighting state when an infrared reflection operation (immediate cutting operation) exceeding the set time T2 is performed during the delay operation of the holding time timer 13b.

  In step S7, if the detection time is within the set time T2, the main control unit 13 continues to stop the holding time timer 13b. Thereby, as shown to the middle stage of FIG.5 (c), the illumination load 10 continues an ON state (lighting state). As described above, when the infrared reflection operation (continuous ON operation) is performed within the set time T2 during the period in which the illumination load 10 is delayed and turned off (extinguishes), the illumination load 10 continues the lighting state.

  In addition, when the illumination load 10 is in an on state (lighted state), the main control unit 13 determines that the holding time timer 13b is in the set time T2 (for example, 2 seconds) when the detection time measured by the time measuring unit 13a is within the set time T2 (for example, 2 seconds). Is operated to control the load control I / F unit 19 to delay the illumination load 10 and turn it off (extinguish). That is, the illumination load 10 is turned off after the lapse of the delay time T1 (for example, 3 minutes) as shown in the subsequent stage of FIG.

  Further, when the illumination load 10 is in an on state (lighted state), the main control unit 13 immediately turns off the illumination load 10 when the detection time counted by the timing unit 13a exceeds the set time T2 ( The load control I / F unit 19 is controlled so as to be turned off. That is, the illumination load 10 is turned off immediately.

  As described above, in the proximity switch device 1, an object such as a hand or a finger is held close to the front of the translucent plate 5, and the reflected infrared ray reflected from the object is detected by the infrared light receiving detection unit 17. The lighting load 10 is turned on and off in reverse. When the illumination load 10 is in the on state (lighted state), the main control unit 13 and the load control I / F unit 19 (load control unit) detect the continuous reflected infrared rays detected by the time measuring unit 13a. Accordingly, the lighting load 10 is controlled to be delayed (turned off) with delay, or the lighting load 10 is turned off (turned off) immediately. That is, the proximity switch device 1 changes the detection time of continuous reflected infrared rays according to the time for which an object such as a hand or a finger is held in front of the translucent plate 5, and selectively selects the illumination load 10 according to the detection time. It is formed so that it can be turned off (extinguished) with a delay, or can be turned off (extinguished) immediately. Therefore, since the proximity switch device 1 can diversify the off control of the lighting load 10, it can be appropriately used for lighting control of a toilet or a room.

  Next, a second embodiment of the present invention will be described.

  6 and 7 show a second embodiment of the present invention, FIG. 6 is a flowchart showing control of a load of the proximity switch device, and FIG. 7 shows an operation of inversion control of on / off of the load by the proximity switch device. It is explanatory drawing.

  The proximity switch device of the present embodiment is configured in the same manner as the proximity switch device 1 shown in FIGS. 1 to 3, and the control of the main control unit 13 is different. Hereinafter, control by the main control unit 13 will be described with reference to FIGS. 6 and 7.

  When the illumination load 10 is in an off state, an object such as a hand or a finger is placed close to the front of the translucent plate 5 (ON operation), and the infrared light received by the infrared light receiving detector 17 from the infrared LED 14 When the reflected infrared ray reflected from the object is detected, the main control unit 13 causes the load control I / F unit to immediately turn on the illumination load regardless of the detection time of the reflected infrared ray counted by the time measuring means 13a. 19 is controlled. As a result, the illumination load 10 is immediately turned on (lighted) as shown in FIGS. 7 (a) to 7 (c).

  And the main control part 13 operates the holding | maintenance time timer 13b simultaneously with the lighting load 10 being ON-controlled. When the holding time timer 13b times up to a predetermined holding time T3, for example, 3 minutes, the main control unit 13 controls the load control I / F unit 19 as shown in FIG. The load 10 is turned off (extinguished). That is, when the reflected infrared ray is detected by the infrared light receiving detector 17, the illumination load 10 is on-controlled (lighting control) for a predetermined holding time T3 (for example, 3 minutes). The main control unit 13 and the load control I / F unit 19 turn on the illumination load 10 for a predetermined holding time T3 (for example, 3 minutes) when the reflected infrared ray is detected by the infrared light receiving detection unit 17. A load control means is formed.

  Then, it is determined whether or not the infrared light receiving detection unit 17 has detected the reflected infrared ray over the period of the holding time operation in which the holding time timer 13b is operating (FIG. 6, step S11). If the reflected infrared ray is not detected, the holding time timer 13b continues to count (step S12). The measurement of the holding time timer 13b is continued until the reflected infrared ray is detected by the infrared light receiving detector 17 or until a predetermined holding time T3 (3 minutes) is measured (step S13).

  In step S13, when the holding time timer 13b measures the predetermined holding time T3 (3 minutes) and the time is up, the main control unit 13 sets the load control I / F unit 19 as shown in FIG. The lighting load 10 is turned off (extinguished) by controlling (step S14). That is, when the lighting load 10 is turned on (ON), it is turned on for a predetermined holding time T3 (3 minutes) and then automatically turned off.

  Then, when the reflected infrared ray is detected by the infrared light receiving detector 17 during the holding time operation of the holding time timer 13b (step S11), the main controller 13 detects the continuous reflected infrared rays timed by the time measuring means 13a. Detection time measurement processing is executed (step S15). Then, it is determined whether the detection time is within a set time T2 (for example, 2 seconds) set or exceeds the set time T2 (step S16).

  If the detection time exceeds the set time T2, the main control unit 13 controls the load control I / F unit 19 to immediately turn off the illumination load 10 as shown in FIG. 7B. It is turned off (step S14). That is, the illumination load 10 is subjected to an infrared reflection operation (immediate cutting operation) exceeding a set time T2 in which an object such as a hand or a finger approaches the front of the translucent plate 5 during the holding time operation of the holding time timer 13b. And immediately turn off the light.

  In step S16, if the detection time is within the set time T2, the main control unit 13 resets the time of the holding time timer 13b and re-measures time (step S17). That is, the illumination load 10 is turned on again (lighting control) for a predetermined holding time T3 (3 minutes) from the detection time point when the reflected infrared ray is detected by the infrared light receiving detector 17. As shown in FIG. 7C, the illumination load 10 continues to be lit for a predetermined holding time T3 (3 minutes) from the detection time point, and then automatically turns off. In this way, the illumination load 10 performs the infrared reflection operation (restart operation) within the set time T2 during the holding time operation in which the holding time timer 13b measures the predetermined holding time T3 (3 minutes). Then, the lighting state is continued for a predetermined holding time T3 (3 minutes).

  As described above, the proximity switch device according to the present embodiment holds an object such as a hand or a finger in front of the translucent plate 5, and when the reflected infrared ray reflected from the object is detected by the infrared light receiving detection unit 17. The lighting load 10 is on-controlled (lighting control) for a predetermined holding time T3 (3 minutes). When the reflected infrared light is detected by the infrared light receiving detection unit 17 when the illumination load 10 is in the on state (lighting state), the main control unit 13 and the load control I / F unit 19 (load control means) Depending on the detection time of the continuous reflected infrared rays timed by the time measuring means 13a, the illumination load 10 is turned on again (lighting control) over the holding time T3 (3 minutes) from the detection time point, or the illumination load 10 Is controlled to be turned off (turned off) immediately. That is, in the proximity switch device, the detection time of the continuous reflected infrared rays changes depending on the time of holding an object such as a hand or a finger in front of the translucent plate 5, and the lighting load 10 is turned on (ON) according to the detection time. Control from the state) to extinguishing (off) is selectively delayed or immediately moved. Therefore, since the off control of the lighting load 10 is diversified, the proximity switch device can be appropriately used for the lighting control of the toilet or the room.

  Next, a third embodiment of the present invention will be described.

  8 to 10 show a third embodiment of the present invention, FIG. 8 is a block diagram of a two-wire illumination control system using a proximity switch device, and FIG. 9 shows control of a load of the proximity switch device. FIG. 10 is an explanatory diagram showing a load operation by the proximity switch device. The same parts as those in FIG.

  In FIG. 8, a two-wire illumination control system 21 using the proximity switch device 20 is shown. The illumination control system 21 includes the proximity switch device 20 and the illumination device 9. The illumination load 10 is connected in series to the AC power source Vs, and is controlled to be turned on / off or dimmed by the proximity switch device 20.

  The proximity switch device 20 includes a load control interface (I / F) unit 22 connected in series to the AC power supply Vs via the illumination load 10, and includes, for example, a three-terminal thyristor SCR1. The load control I / F unit 22 performs on / off control of the lighting load 10 under the control of the main control unit 13, or controls the phase of the AC voltage of the AC power supply Vs to dimm the lighting load 10. The configuration is the same as that of the proximity switch device 1 shown in FIG. The control for dimming and lighting the lighting load 10 indicates that the power consumption of the lighting load 10 is adjusted and controlled.

  The main control unit 13 loads so that the on / off of the illumination load 10 is inverted or controlled according to the detection (detection time) of the reflected infrared light of the infrared light reception detection unit 17 or the illumination load 10 is dimmed. The control I / F unit 22 is controlled. The main control unit 13 and the load control I / F unit 22 perform on / off inversion control of the lighting load 10 or dimming control of the lighting load 10 according to the detection time timed by the time measuring unit 13a (the power consumption of the lighting load 10 is controlled). Load control means for adjusting control) is formed.

  Next, control by the main control unit 13 will be described with reference to FIGS. 9 and 10.

  When the illumination load 10 is in an off state, an object such as a hand or a finger is placed close to the front of the translucent plate 5 (ON operation), and the infrared light received by the infrared light receiving detector 17 from the infrared LED 14 When the reflected infrared ray from the object is detected, the main control unit 13 sets the load control I / F unit 22 so as to immediately turn on the illumination load 10 regardless of the detection time of the reflected infrared ray counted by the time measuring means 13a. Control. As a result, the illumination load 10 is immediately turned on (lighted) as shown in FIGS. 10 (a) and 10 (b).

  Then, when an object such as a hand or a finger is held in front of the translucent plate 5 of the proximity switch device 20 again, the infrared light receiving detection unit 17 detects from the infrared object emitted from the infrared LED 14. The reflected infrared ray is detected, and the time measuring means 13a re-measures the continuous detection time of the reflected infrared ray. Then, it is always determined whether or not the infrared light receiving detection unit 17 detects the reflected infrared ray (step S31).

  When the reflected infrared ray is detected by the infrared light receiving detection unit 17, the main control unit 13 executes a process of measuring the continuous detection time of the reflected infrared ray timed by the time measuring means 13a (step S32). Then, it is determined whether the detection time is within a set time T2 (for example, 2 seconds) or exceeds the set time T2 (step S33).

  When the detection time exceeds the set time T2, as shown in FIG. 10A, the main control unit 13 controls the load control I / F unit 22 to light up the illumination load 10 in all light. The dimming is turned on (step S34). In other words, when the infrared load operation (dimming operation) exceeding the set time T2 is performed while all the lights are lit, the illumination load 10 is dimly lit immediately after all the lights are lit.

  When the detection time is within the set time T2, the main control unit 13 controls the load control I / F unit 19 to invert the operation state of the lighting load 10 as shown in FIG. Control (step S35). That is, the illumination load 10 is controlled to be turned off from the lighting state.

  As described above, the proximity switch device 20 changes the detection time of continuous reflected infrared rays depending on the time for which an object such as a hand or a finger is held in front of the translucent plate 5, and the illumination load 10 is changed according to the detection time. It is possible to selectively perform on / off control (light on / off control) or dimming / lighting control (power consumption adjustment control). Therefore, the proximity switch device 20 can diversify the control of the lighting load 10, and can be used for various lighting controls such as a toilet or a room.

  Note that power consumption adjustment control (such as dimming / lighting control of the illumination load 10) may be gradually changed (fade) according to the length of detection time of the reflected infrared rays.

  Next, a fourth embodiment of the present invention will be described.

  FIG. 11 is a block diagram of a proximity switch device showing a fourth embodiment of the present invention, and FIG. 12 is a block diagram of another proximity switch device. The same parts as those in FIGS. 3 and 8 are denoted by the same reference numerals, and description thereof is omitted.

  The proximity switch device 23 shown in FIG. 11 is different from the proximity switch device 1 of the illumination control system 8 shown in FIG. 3 in that it has a counting means (counter) 13c instead of the time measuring means 13a and a main control unit 24 is configured. Yes. Further, the proximity switch device 25 shown in FIG. 12 has a main control unit 24 instead of the main control unit 13 in the proximity switch device 20 of the illumination control system 21 shown in FIG.

  The counting means (counter) 13c constitutes an integrating means, and counts (counts) the number of intermittent detections within a predetermined time (for example, 3 seconds) of the reflected infrared light detected by the infrared light receiving detector 17. That is, the number of detections that the infrared light receiving detection unit 17 (detection means) detects by detecting the presence or movement of a human body such as a finger or a hand is counted. And the main control part 24 and load control I / F part 19 (or load control I / F part 22) as a load control means control the illumination load 10 according to the said detection frequency. That is, in the above first embodiment, when the lighting load 10 is in the on state (lighted state), the lighting load 10 is delayed and turned off (turned off) according to the number of detections, or the lighting load 10 is immediately turned on. To turn off (extinguish). For example, when the number of detection times is a predetermined number of times, for example, 2 times or less, the lighting load 10 is turned off (turns off) with a delay, and when the number of detection times exceeds a predetermined number (two times), Off (lights off).

  In the second embodiment described above, when the reflected infrared ray is detected by the infrared light receiving detection unit 17 when the illumination load 10 is in the on state (lighting state), the main control unit 24 and the load control I / F unit 19, the lighting load 10 is turned on (lighting control) again for a predetermined holding time T3 (for example, 3 minutes) from the time of detection, or the lighting load 10 is turned off (turned off immediately) according to the number of times of detection. ) For example, when the number of times of detection is equal to or less than a predetermined number (two times), the illumination load 10 again reaches a predetermined holding time T3 (for example, 3 minutes) from the time when the reflected infrared ray is detected by the infrared light receiving detector 17. When turned on (lighted) and then turned off (lights off), when the number of detections exceeds a predetermined number (twice), the lighting load 10 is immediately turned off (lights off).

  In the third embodiment, the main control unit 24 and the load control I / F unit 22 reversely control on / off of the lighting load 10 or dimming control of the lighting load 10 according to the number of detections. (Power consumption adjustment control) For example, when the number of times of detection is a predetermined number (two times) or less, the lighting load 10 is turned off (lights off) when in an on state (lighted state), and is turned on (lighted) when in an off state (lighted state). When the number of detections exceeds a predetermined number (twice), the illumination load 10 is dimmed (for example, 50% lit).

  As described above, in the proximity switch devices 23 and 25, the off control (light extinction control) of the illumination load 10 is diversified according to the number of detections counted by the counting unit 13c. That is, off control (light-off control) of the illumination load 10 can be diversified according to the number of times a human body such as a finger or hand is intermittently held within a predetermined time (for example, 3 seconds) close to the translucent plate 5. .

  The proximity switch devices 23 and 25 may include both the counting unit 13c and the time measuring unit 13a, and may control the illumination load 10 according to both the number of detections and the detection time.
