Since it moves in the direction approaching the portion 26, the ceiling material is sandwiched between the clamping piece 27c and the flange portion 26, so that the body 25 can be attached to the ceiling material.

  Moreover, Fig.3 (a) has shown the state which attached the control mode changeover switch 3 and the absence mode setting switch 4 used with the thermal automatic switch 1 to the attachment frame 30 standardized for the embedded wiring apparatus, These switches 3 and 4 are embedded in a wall near the entrance inside the building, for example, using an attachment frame 30. The body of the control mode changeover switch 3 has a size (two module dimensions) corresponding to two wiring appliances of unit dimensions (one module dimension) that can be attached to the mounting frame 30 in the short width direction and can be attached up to three. The container of the answering mode setting switch 4 is formed to have the one module size described above.

  The control mode changeover switch 3 is provided with a rotary dial 32 for switching the built-in contact portion 31 so as to be rotatable on the front surface of the body. The switching state of the contact portion 31 is changed according to the rotational position of the rotary dial 32. When the mark 32a of the rotary dial 32 is adjusted to the positions of “OFF”, “AUTO”, and “CONTINUOUS ON” displayed on the front surface of the body, the contact portion 31 is set to “OFF mode”, “AUTO mode”, “ It is possible to switch to the “continuous mode” switching position.

  The answering mode setting switch 4 is a push-on / push-off type push button switch, and the push button of the push button switch is exposed on the front surface of the body. Further, an operation handle 33 is pivotally supported on the front surface of the body, and when one end side (right side portion) of the operation handle 33 is pushed, the operation handle 33 is rotated and the push button is pushed on the back surface. It comes to push. In addition, the operation handle 33 is provided with a transparent portion 33b at the center in the vertical direction on the right side, and the operation handle 33 displays a name card attached to the back side (for example, “absence mode” character indicating the use of the switch). It is formed so as to be visible from the front surface of. In addition, a window hole 33a is formed on the left side of the operation handle 33, and on the back side of the operation handle 33, a portion corresponding to the window hole 33a is alternately turned upward or downward depending on the pressing operation of the operation handle 33. The display member 34 in which the part exposed from the window hole 33a is switched by moving to is arranged. In addition, in the state where the answering mode setting switch 4 is switched to the answering mode setting position according to the pressing operation of the operation handle 33, the position of the display member 34 exposed from the window hole 33a is changed to yellow or fluorescent. As a conspicuous color such as a color, for example, a character such as “absence mode” is displayed, and the switching state of the operation mode can be easily determined from the display on the display member 34.

  Next, the operation when the rotary dial 32 of the control mode changeover switch 3 is switched to the “automatic” position will be described. In this case, the lighting automatic switch 1 controls the lighting load 2 to be turned on / off. First, the operation mode of the thermal automatic switch 1 (that is, the signal processing unit 13) is determined by the mode setting signal input from the absence mode setting switch 4. The operation when is set to the normal mode will be described.

  In the normal mode, the signal processing unit 13 controls the lighting load 2 to be turned on only when the ambient illuminance detected by the brightness sensor 12 is darker than a predetermined reference value and the human sensor 11 detects a human body. When the control signal is input from the signal processing unit 13, the output driving unit 14 turns on the lighting load 2 for a predetermined time by turning on the above-described switch element. When the detected illuminance of the brightness sensor 12 is brighter than the reference value or when the human sensor 11 does not detect a human body, the signal processing unit 13 outputs a control signal for turning off the illumination load 2. The output driving unit 14 turns off the switch element and turns off the illumination load 2.

  On the other hand, when the operation mode of the signal processing unit 13 is set to the absence mode by the mode setting signal input from the absence mode setting switch 4, the human body sensor 11 detects the human body detection signal regardless of the detected illuminance of the brightness sensor 12. Is input, the signal processing unit 13 outputs a control signal for blinking the switch element at a predetermined cycle to the output drive unit 14, and the output drive unit 14 periodically turns the switch element on and off, The lighting load 2 blinks, the no-voltage contact 15 is closed, a contact signal is output to a threatening device such as the security camera 8 or the speaker 7 provided in the room, and an alarm sound is output from the speaker 7. The operation is performed and the security camera 8 is operated (see FIG. 4). Further, the signal processing unit 13 blinks the operation indicator lamp 16 provided in the thermal automatic switch 1 itself when detecting a human body, and outputs an alarm sound from the alarm sound generation unit 17.

  As described above, in this embodiment, the answering mode setting switch 4 is connected to the mode switching terminals T5 and T6, and the mode switching signal is input in accordance with the switching operation of the answering mode setting switch 4, whereby the signal processing unit 13 ( The operation mode of the thermal automatic switch 1) can be switched to either the normal mode or the absence mode. In the normal mode, the illumination load 2 is lit for a predetermined time based on the human body detection signal of the human sensor 11, and in the absence mode, the human body is switched on. Since the threatening operation by light and sound is performed based on the detection signal, either the lighting control of the lighting load 2 or the threatening operation by the threatening means is performed by switching the operation mode of one thermal automatic switch 1. Can be performed. When the human sensor 11 detects a human body in the absence mode, the signal processing unit 13 blinks the operation indicator lamp 16 provided in the illumination load 2 or the thermal automatic switch 1 and generates an alarm sound from the alarm sound generation unit 17. In addition, by using a non-voltage contact 15 to send a contact signal to the outside, a threatening operation by an external threatening device is performed, and by performing a combination of a plurality of threatening operations, the ambient brightness is lost. Even if the blinking of the lighting load 2 is not conspicuous, the effect of threatening a suspicious person can be enhanced.

  In the absence mode, a predetermined delay time (for example, 1 minute) may be provided between when the human body detection signal of the human sensor 11 is input and when the signal processing unit 13 performs a threatening operation. When going out or returning home, prevent the threatening action by locking out the entrance door before the above delay time elapses, or opening the entrance door and entering the house. It is possible to perform a threatening operation only on a suspicious person who has remained in the detection area of the human sensor 11 for a long time exceeding the delay time.

  For example, in a period (daytime) when the detected illuminance of the brightness sensor 12 is brighter than a predetermined reference value, the signal processing unit 13 performs a threatening operation until the above delay time elapses after the human body detection signal is input. If the human body detection signal from the human sensor 11 is input for the delay time or longer, the threatening operation may be performed, and the threatening operation can be prevented from being performed on the householder. Further, in a period (nighttime) when the detected illuminance of the brightness sensor 12 is darker than a predetermined reference value, the signal processing unit 13 is in the normal mode until the delay time elapses after the human body detection signal is input. The lighting load 2 is controlled in the same manner as described above, and if the human body detection signal from the human sensor 11 is continuously input for the delay time or longer, the above threatening operation may be performed. When the person goes home or goes out, the lighting load 2 is lit until the delay time elapses, thereby ensuring the light necessary for unlocking or locking the key, and when the delay time elapses. If the suspicious person stays for a long time exceeding the delay time before the entrance, the threatening action can be performed to threaten the suspicious person.

  Further, in this embodiment, the operation handle 33 of the absence mode setting switch 4 is provided with a transparent portion 33b so that the characters on the name card can be visually recognized through the transparent portion 33b. Can be confirmed. Further, when the operation handle 33 of the answering mode setting switch 4 is pushed to change the operation mode of the thermal automatic switch 1 to the answering mode, the display of the display member 34 exposed from the window hole 33a of the operation handle 33 is switched, Since the character “absence mode” can be visually recognized through the window 33a, it can be easily recognized that the mode has been switched to the absence mode. Here, a display means indicating that the mode is the switching of the absence mode is configured from the name card, the display member 34, and the like arranged on the back side of the transparent portion 33b.

  By the way, recently, a person who intends to enter the house may enter the house pretending to be a visiting salesperson or the like, and at that time, from the display of the operation handle 33 of the absence mode setting switch 4, Since there is a possibility that the threatening action using the lighting load 2 or the like is set, the display of the operation handle 33 is not displayed as shown in FIG. 3B, and the color of the operation handle 33 is changed. By setting the color different from the color used for general wiring equipment (for example, white, gray, etc.) (for example, yellow, red, orange, etc.) You may make it distinguishable. In this case, the operation handle 33 itself serves as a display means for indicating that the absence mode is switched. Further, if the characters “ON” and “OFF” are displayed on the portion of the display member 34 exposed from the window hole 33a of the operation handle 33 when the absence mode or the normal mode is set, it is not understood by an outside person. The family member can easily grasp from the display on the display member 34 whether the current operation mode is the normal mode or the absence mode.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. In the thermal automatic switch 1 of the first embodiment described above, the absence mode setting switch 4 is connected between the mode switching terminals T5 and T6, whereas in this embodiment, as shown in FIG. A commercial power source AC is connected between the mode switching terminals T5 and T6 via the absence mode setting switch 4. In addition, since it is the same as that of Embodiment 1 except the connection form of the absence mode setting switch 4, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

  In the first embodiment described above, since the operation mode is switched by short-circuiting or opening the mode switching terminals T5 and T6 by the answering mode setting switch 4, a separate answering function is provided between the terminals T5 and T6 of the individual thermal automatic switches 1. It is necessary to connect the mode setting switch 4, and only one operation mode of the thermal automatic switch 1 can be switched by one absence mode setting switch 4.

  On the other hand, in this embodiment, since the voltage signal (the power supply voltage of the commercial power supply AC) is applied between the mode switching terminals T5 and T6 when the absence mode setting switch 4 is turned on, a plurality of thermal automatic switches are provided. A commercial power supply AC can be connected between one mode switching terminal T5 and T6 via the same answering mode setting switch 4, and the operation mode of the thermosensitive automatic switch 1 at a plurality of locations can be switched by one answering mode setting switch 4. It is possible to reduce the trouble of switching the operation mode.

  Further, in this embodiment, when the operation mode is switched to the absence mode, a current flows through the absence mode setting switch 4, so that the current transformer 42 is connected in series with the contact part 41 of the absence mode setting switch 4 as shown in FIG.

For example, a character “absence mode” is displayed on the transmissive part 35 by a method such as printing, and a lit display lamp serving as a lit display means. When "44" is lit, the "absence mode" character appears and can be seen, and when the lighting display lamp 44 is extinguished, the character in the "absence mode" cannot be seen.

  Accordingly, when the absence mode is set, the lighting display lamp 44 is turned on, and the characters “absence mode” on the transmission portion 35 can be visually recognized. Therefore, it can be easily understood that the absence mode is set, and the absence mode is set. When you cancel (being operating in normal mode), the characters “absence mode” on the transparent part 35 will not be visible, so a suspicious person may call a visiting salesperson when the family member is at home (that is, when the absence mode is released). Even if the user enters and looks inside the house, the absence mode setting switch 4 can make it difficult for an outside person to understand that the absence mode can be set.

And the state in which the lighting load 2 is continuously lit are alternately switched. Further, when an operation (so-called one-to-two operation) for continuously pressing the handle body 70 twice within a predetermined time is performed, an operation input from the push button switch 36 to the contact switching unit 37 is continued twice within the predetermined time. Therefore, the contact switching unit 37 switches the control mode of the illumination load 2 to the “automatic mode” by switching the contact unit 31 to the “automatic mode” switching position. Further, when the handle main body 70 is operated once in a state where the automatic mode is set, an operation input is given from the push button switch 36 to the contact switching unit 37, and the contact switching unit 37 moves the contact unit 31. The switch position is switched to the “OFF mode” switching position, and both the control mode switching operation and the operation mode switching operation in the automatic mode can be performed by one absence mode setting switch 4.

  The order of switching the control mode by pressing the handle body 70 is not limited to the above order. For example, every time the handle body 70 is operated, the control mode is alternately switched between “OFF mode” and “AUTO mode”. May be switched to “continuous mode” by performing the above-described one-two operation.

(Embodiment 6)
A sixth embodiment of the present invention will be described with reference to FIGS. In addition, since the structure of the thermal automatic switch 1 is the same as that of the thermal automatic switch 1 of Embodiment 1 mentioned above, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

  In the thermosensitive automatic switch 1 of each embodiment described above, when the human sensor 11 detects a human body during the setting of the absence mode, the signal processing unit 13 is based on the human body detection signal input from the human sensor 11. The intimidating action described in 1 (blinking of the lighting load 2) is performed, but when operating in the absence mode in the daytime when the surroundings are bright, there are many external noises such as far-infrared rays contained in sunlight. There is a possibility that erroneous detection of the human sensor 11 may occur under the influence of the above. On the other hand, when operating in the normal mode or absence mode at night, it is preferable to turn on the illumination load 2 by detecting a person in the detection area early.

  Therefore, in the present embodiment, the signal processing unit 13 serving as an erroneous detection suppression unit switches the detection sensitivity of the human sensor 11 between two levels, high and low, according to the surrounding brightness. FIG. 19 shows the detection output of the human sensor 11. When the signal output of the human sensor 11 exceeds a predetermined threshold value, the signal processing unit 13 determines that a human body detection signal has been input. The detection sensitivity of the human sensor 11 is changed by changing the brightness according to the brightness. That is, at night when the detected illuminance of the brightness sensor 12 is darker than the predetermined reference value, the signal processing unit 13 sets the detection output threshold value to th1 and sets the sensitivity of the human sensor 11 to high sensitivity. On the other hand, during the daytime when the detected illuminance of the brightness sensor 12 is brighter than a predetermined reference value, the signal processing unit 13 switches the detection output threshold value to a value th2 that is higher than the nighttime threshold value th1, and the sensitivity of the human sensor 11 Is switched to a lower sensitivity than at night to prevent erroneous detection of the human sensor 11 due to external noise or the like.

  In the present embodiment, when the detected illuminance of the brightness sensor 12 is brighter than a predetermined reference value, the detection sensitivity of the human sensor 11 is reduced compared to the case where the detected illuminance is darker than the reference value. Although the false alarm of the human sensor 11 due to external noise such as light is suppressed, when the detected illuminance of the brightness sensor 12 is brighter than a predetermined reference value in the absence mode, the signal processing unit 13 serving as a false detection suppression unit. However, erroneous detection may be suppressed by causing a threatening operation to be performed when the condition that the human body detection signal is input from the human sensor 11 a predetermined number of times or more is satisfied. FIG. 20A shows the detection output of the human sensor 11, and when the detection output of the human sensor 11 exceeds a predetermined threshold th1, the signal processing unit 13 generates a human body detection signal (FIG. 20B). )reference). Here, FIG. 20C shows a period during which the illumination load 2 is turned on in the normal mode. When the human body detection signal is input once in the signal processing unit 13, the output drive unit 14 immediately causes the illumination load to be illuminated. Since 2 is turned on, the illumination load 2 can be turned on in a short time when illumination is necessary at night. FIG. 20D shows an operation when the detected illuminance of the brightness sensor 12 is brighter than a predetermined reference value in the absence mode, and the signal processing unit 13 outputs the human body detection signal a predetermined number of times (for example, three times). At the time when the input condition is satisfied, a threatening operation is performed by, for example, blinking the illumination load 2 by the output driving unit 14. Thus, when the human body detection signal is not input more than a predetermined number of times, the signal processing unit 13 is prevented from performing a threatening operation by the output driving unit 14, and thus malfunction due to external noise can be suppressed.

  In addition, when the signal processing unit 13 serving as a false detection suppression unit has a detection illuminance of the brightness sensor 12 brighter than a predetermined reference value in the absence mode, the human body detection signal is output from the human sensor 11 within a predetermined time (for example, 5 seconds). It is also possible to suppress false detection by performing a threatening operation when the condition that the number of times is input a predetermined number of times or more is satisfied (see FIG. 21). That is, the signal processing unit 13 performs a threatening operation by the output driving unit 14 when the human body detection signal is input three or more times from the human sensor 11 within the predetermined time TA, for example, at time t11 in FIG. When the human body detection signal is input, since the human body detection signal is not performed three times or more from the time t11 until the predetermined time TA elapses, the signal processing unit 13 does not perform a threatening operation. On the other hand, when the human body detection signal is input at time t12, the human body detection signal is input three or more times from the time t12 until the predetermined time TA elapses. Intimidating actions such as blinking the lighting load 2 are performed. In this way, when the human body detection signal is not input more than a predetermined number of times within a predetermined time, the signal processing unit 13 is prevented from performing a threatening operation by the output driving unit 14, thereby suppressing malfunction due to external noise. it can.

(Embodiment 7)
A seventh embodiment of the present invention will be described with reference to FIGS. In addition, since the structure of the thermal automatic switch 1 is the same as that of the thermal automatic switch 1 of Embodiment 1 mentioned above, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

  In the thermosensitive automatic switch 1 of each embodiment described above, when the human sensor 11 detects a human body during the setting of the absence mode, the signal processing unit 13 is based on the human body detection signal input from the human sensor 11. The intimidating action described in 1 (blinking of the lighting load 2) is performed, but when operating in the absence mode in the daytime when the surroundings are bright, there are many external noises such as far-infrared rays contained in sunlight. There is a possibility that erroneous detection of the human sensor 11 may occur under the influence of the above.

  Therefore, in the thermal automatic switch 1 of each embodiment described above, only one human sensor 11 is provided, whereas in this embodiment, a highly sensitive human sensor 11a for detecting a human body at night. Apart from that, the detection area is set to the same area as the human sensor 11a, and the human sensor 11b for daytime detection whose detection sensitivity is lower than that of the human sensor 11a is provided. In the absence mode, the brightness sensor 12 is provided. When the ambient illuminance detected by the sensor is brighter than a predetermined reference value, the signal processing unit 13 serving as a false detection suppression means is only output when the two human sensors 11a and 11b generate human body detection signals. 14, threatening operations such as blinking the illumination load 2 are performed.

  FIG. 23A shows the detection outputs of the human sensors 11a and 11b. Since both the sensors have the same detection area, the detection outputs are also substantially the same. Here, since the threshold th2 of the human detection sensor 11b for daytime detection is set higher than the threshold th1 of the human detection sensor 11a for night detection, the human detection sensor 11b is compared with the human detection sensor 11a. Therefore, the sensitivity becomes low (see FIGS. 2B and 2C). Then, in the signal processing unit 13, only when a human body detection signal is input from both human sensors 11a and 11b as shown in FIG. When the human body detection signal is inputted only from the high-sensitivity human sensor 11a, the threatening operation is not performed, so that the malfunction is caused by the external noise such as sunlight. Can be prevented.

  In this embodiment, two human sensors 11a and 11b are used. However, three or more human sensors 11 having different detection sensitivities and having the same detection area are provided, and all human sensors are provided. The threatening operation may be performed only when 11 generates a human body detection signal.

(Embodiment 8)
An eighth embodiment of the present invention will be described with reference to FIG. In addition, since the structure of the thermal automatic switch 1 is the same as that of the thermal automatic switch 1 of Embodiment 1 mentioned above, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

  In the thermosensitive automatic switch 1 of each embodiment described above, when the human sensor 11 detects a human body during the setting of the absence mode, the signal processing unit 13 is based on the human body detection signal input from the human sensor 11. The threatening action described in 1 (such as lighting load 2 blinking) is performed, but when operating in the absence mode in the daytime when the surroundings are bright, there are many external noises such as far-infrared rays contained in sunlight. There is a possibility that erroneous detection of the human sensor 11 may occur due to the influence of noise. Further, when small animals such as dogs and cats enter the detection area of the human sensor 11, there is a possibility that these small animals are erroneously detected as human bodies and a threatening operation is performed.

  Therefore, in the thermal automatic switch 1 of each embodiment described above, only one human sensor 11 is provided, whereas in this embodiment, a highly sensitive human sensor 11a for detecting a human body at night. Apart from that, a human sensor 11b for daytime detection having a detection sensitivity lower than that of the human sensor 11a is provided. As shown in FIG. 24A, these two human sensors 11a and 11b overlap each other at the height position corresponding to the human body A, and more than the human body A as shown in FIG. The detection areas are set so that the detection areas do not overlap each other at the height position corresponding to the short small animal B. In the absence mode, when the ambient illuminance detected by the brightness sensor 12 is brighter than a predetermined reference value, the false detection suppression means is used only when both the human sensors 11a and 11b generate human body detection signals. The signal processing unit 13 causes a threatening operation such as blinking of the illumination load 2 by the output driving unit 14.

  Thus, since the signal processing unit 13 does not perform a threatening operation when a human body detection signal is input only from the highly sensitive human sensor 11a, a malfunction occurs due to external noise such as sunlight. Can be prevented. When human body A enters the detection area, human body detection signals are input from both human sensors 11a and 11b, whereas a small animal shorter than human body A enters the detection area. Since a human body detection signal is input from only one human sensor 11a, the signal processing unit 13 does not perform a threatening operation in this case, thereby preventing a malfunction caused by a false detection of a small animal. Can do.

  In the present embodiment, the two human sensors 11a and 11b are used. However, three or more human sensors 11 having different detection sensitivities and set so that detection areas of humans and small animals do not overlap each other are used. It is also possible to cause the threatening operation to be performed only when all human sensors 11 generate human body detection signals.

  In addition, it is apparent that a wide variety of different embodiments can be configured without departing from the spirit and scope of the present invention, and the present invention is not limited to the specific embodiments.
