A space is formed on the back surface side of the bending piece 216 in the cover 21, and the pair of mounting claws 214 and 214 provided on the bending piece 216 are formed by bending the bending piece 216 to the inside of the cover 21. The cover 21 can be elastically retracted from the side surface.

  Here, the attachment frame 7 will be described. The mounting frame 7 is a single unit that can mount three embedded wiring devices having standardized unit module dimensions (one module size) in the longitudinal direction (Z-axis direction in FIG. 1). Three pairs of instrument mounting holes 72 for mounting a wiring instrument are formed on both side pieces 71, 71 surrounding the window hole 70 of the mounting frame 7. The body 2 is fixed to the mounting frame 7 by engaging the mounting claws 214 of the cover 21 with the instrument mounting holes 72. When attaching the container 2 to the attachment frame 7, an attachment claw (not shown) provided on the left side wall of the cover 21 is inserted into the instrument attachment hole 72 of the attachment frame 7 and provided on the right side wall 213. If the front part of the container 2 is inserted into the window hole 70 of the attachment frame 7 so that the attachment claws 214 and 214 are retracted from the side surface of the cover 21, the attachment claws 214 and 214 of the right side wall 213 are attached to the instrument attachment hole 72. And the body 2 is held by the mounting frame 7. On the other hand, when removing the body 2, if the bending piece 216 is pushed into the inside of the cover 21, the mounting claws 214, 214 provided on the bending piece 216 come out of the device mounting hole 72 and come out of the mounting frame 7. The body 2 can be removed.

  Each of the upper and lower frame pieces 73, 73 of the attachment frame 7 is formed with one long hole 74, 74 for inserting the box screws 740, 740. The box screw 740 inserted through each of the long holes 74 is screwed into a screw portion (not shown) of an embedded box embedded in a construction surface such as a wall surface, so that the mounting frame 7 is constructed with a construction material ( The rear portion of the container 2 fixed to the mounting frame 7 is buried in the construction material. Furthermore, each frame piece 73 is formed with a pair of screw holes 75 for plate screws. The mounting frame 7 is screwed using a plate frame (not shown) and a plate screw (not shown) formed in a rectangular frame shape with synthetic resin on the front side. A decorative plate 76 is detachably attached to the front side of the plate frame. Each of the plate frame and the decorative plate 76 is formed with a window hole 760 that is longer and wider than the window hole 70 of the mounting frame 7 so that the front surface of the automatic switch 1 with a heat ray sensor is exposed through the window hole 760. It has become.

  Two circular window holes 220 and 221 are formed in the cover 21, and one circular window hole 222 smaller than these window holes 220 and 221 is formed. Further, on the front surface of the cover 21, a projecting portion 223 that protrudes forward is provided. An opening 226 is formed in the front surface of the protruding portion 223. Arc-shaped protrusions 227 and 228 are provided above and below the opening 226.

  Further, the cover 21 includes a pair of shaft portions 231 and 231 that are integrally provided so as to protrude forward from the left end portion of the front surface 230 in order to pivotally mount the operation handle 3. The front end portion of each shaft portion 231 is formed in a columnar shape along the longitudinal direction of the cover 21.

  The operation handle 3 has a dimension in which the left-right direction is substantially the same as the left-right direction (short direction) of the window hole 760 of the decorative plate 76, and the vertical direction is approximately two-thirds of the vertical direction (longitudinal direction) of the window hole 760. It is formed in the shape of a rectangular plate with a synthetic resin. The operation handle 3 includes a bearing portion (not shown) provided on the back surface of the left side portion 30. The bearing handle is pivotally supported by the shaft portions 231 and 231 of the cover 21 so that the operation handle 3 is rotated to the front surface 230 of the body body 2 so as to cover the upper half of the front surface 230 of the body body 2. It is supported freely.

  Further, the operation handle 3 includes a push projection 31 provided on a back surface provided at a portion facing a later-described operation element 610 exposed on the front surface 230 of the cover 21. When the right side portion 32 of the operation handle 3 is pushed, the operation handle 3 rotates about the shaft portions 231 and 231, the operation element 610 is pushed by the push protrusion 31 of the operation handle 3, and the operation switch 61 is turned on. Turn on. On the other hand, when the pressing force disappears from the operation handle 3, the operation handle 3 receives the reaction force of the operation element 610 and returns to the return position, and the operation switch 61 is turned off. Since the operation handle 3 has the left edge pivotally supported by the shaft portions 231 and 231 in surface contact with the front surface of the mounting frame 7, even if the left side portion 30 of the operation handle 3 is pressed, the operation handle 3 It can be prevented from tilting.

  Further, the operation handle 3 has a thin portion 33, and a portion corresponding to the window holes 220 and 221 of the cover 21 in the thin portion 33 has an operation holding time setting portion (setting operation portion) 62 and a brightness sensor described later. Opening windows 34 and 35 are formed at portions facing the operation holding time setting unit 62 and the brightness sensor adjustment unit 63 in order to allow the adjustment unit 63 to be inserted therethrough. In the operation handle 3, a through hole 36 into which a light guide member (not shown) is fitted is formed at a substantially central portion in the vertical direction (Z-axis direction in FIG. 1) of the left side portion 30. The light guide member is formed of a light-transmitting synthetic resin, and is attached to the back side of the operation handle 3 in a state of being fitted into the through hole 36. Thereby, the irradiation light of the light emitting diode LD accommodated in the container 2 is emitted forward from the through hole 36 of the operation handle 3 through the light guide member held by the operation handle 3.

  The light emitting diode LD displays an operation mode by, for example, a color or a lighting state. For example, in the case of display by color, when the illumination load L is continuously lit, it is lit red, when it is automatically lit, it is lit green, and when the illumination load L is forcibly turned off, it is turned off. On the other hand, for example, in the case of display by lighting state, when the lighting load L is continuously lit, it is continuously lit, blinking when it is automatically lit, and turned off when the lighting load L is forcibly turned off. .

The operation handle 3 is attached to the upper side of the cover 21, while the decorative cover 37 is attached to the lower side of the cover 21. The decorative cover 37 has an opening 371 is formed at a position opposed to the apertures 226.

  The handle cover 4 is pivotally attached to the front surface of the operation handle 3 so as to cover the thin portion 33 of the operation handle 3. The horizontal and vertical dimensions of the handle cover 4 are substantially the same as the horizontal and vertical directions of the thin portion 33, respectively. Further, arms 40, 40 projecting sideways project from both upper and lower end portions of the side portion of the handle cover 4, and shafts provided on both upper and lower side surfaces of the operation handle 3 are provided at the tip portions of the arms 40. Rotating shafts 41 and 41 that are pivotally supported by the hole 38 are provided so as to project. As described above, the pivot cover 41 of the arm 40 is pivotally supported in the shaft hole 38 of the operation handle 3, whereby the handle cover 4 has a position where the opening windows 34, 35 are exposed and a position where the opening windows 34, 35 are covered. Is freely attachable to the front surface of the operation handle 3. By using such a handle cover 4, most of the thin portion 33 can be hidden when the handle cover 4 is closed, so that a clean design can be achieved.

  The heat ray sensor 5 includes a sensor element such as a pyroelectric element, and detects a heat ray from a human body existing in a preset region, and is mounted on a circuit board 60 of the circuit unit 6 described later. The heat ray sensor 5 is configured integrally with a brightness sensor 50 such as CdS or a photodiode, and the brightness of the surroundings can be identified by the brightness sensor 50.

  Such a heat ray sensor 5 is covered with a sensor cover 51 on the front side. The sensor cover 51 is formed with a detection window 510 that exposes the heat ray sensor 5. Through this detection window 510, the heat ray sensor 5 detects heat rays from the human body from the outside. The sensor cover 51 is accommodated in the container 2 so as to be sandwiched between the cover 21 and the circuit unit 6.

  A pair of shutters 52, 52 are provided between the sensor cover 51 and the cover 21. Each shutter 52 is integrally provided with an arcuate base 520 and a handle 521 extending from one end of the base 520 with an angle. Each shutter 52 provided between the cover 21 and the sensor cover 51 is movable in the left-right direction and covers a part of the heat ray sensor 5. That is, the base portion 520 is moved by an operation using the handle portion 521 by the user, and the opening / closing state of the detection window 510 of the sensor cover 51 is adjusted. Thereby, since the detection area of the heat ray sensor 5 can be adjusted, a detection area can be optimized.

  The circuit unit 6 is for setting, for example, a circuit board 60 such as a printed wiring board, an operation switch 61 having an operation element 610 that is pushed and driven by the operation handle 3, and a lighting time of an illumination load L (see FIG. 2). An operation holding time setting unit 62 and a brightness sensor adjustment unit 63 for setting the brightness detection level of the brightness sensor 50 are provided and housed in the container 2. A heat sink 64 is provided on the back side of the circuit unit 6.

  The operation element 610 of the operation switch 61 is exposed on the front surface 230 of the container 2 and is pushed and driven by the operation handle 3.

  The operation holding time setting unit 62 is, for example, a rotary switch, and is provided on the front surface 230 of the container 2 and sets the operation holding time T1 by a user operation. As shown in FIG. 3, the operation holding time can be set in a range from 10 seconds to 30 minutes. Thereby, the lighting time of the illumination load L can be optimized. The brightness sensor adjustment unit 63 is a rotary switch, for example, and ranges from “dark” (for example, 5 Lx or less) to “bright” (for example, 100 Lx or more) by the user's operation. This is what you set. Further, when “OFF” is set, the function of the brightness sensor 50 is stopped. Accordingly, it is possible to prevent the lighting load L2 in the house from being turned on when the surroundings are bright, and energy saving can be achieved.

  Here, the circuit configuration of the circuit unit 6 will be described with reference to FIG. The circuit unit 6 inputs outputs from the heat ray sensor 5 and the brightness sensor 50 to a control unit (microcomputer) 65. The control unit 65 performs A / D conversion on the outputs of the heat ray sensor 5 and the brightness sensor 50, and further determines the presence / absence of a person in a preset detection area based on the output value of the heat ray sensor 5. Inside the controller 65, when it is determined that a person is present in the detection area based on the output of the heat ray sensor 5, a human body detection signal is generated.

  The control unit 65 has a function of turning on / off an opening / closing element 651 such as a triac via the drive unit 650. The opening / closing element 651 is connected between a power supply terminal 652 for connecting the commercial power supply AC and a load terminal 655 for connecting the lighting load L, and the conduction angle is controlled by the control unit 65 to adjust the power supplied to the lighting load L. Then, the lighting load L is turned on with a desired light output. The power supply terminals 652 and 653 are connected to a stabilized DC power supply 656 that receives a commercial power supply AC and generates a constant DC voltage. The stabilized DC power supply 656 supplies operating power to the internal circuit.

  The basic operation of the controller 65 is based on a change in the heat dose incident on the heat ray sensor 5 in a state where the brightness detected by the brightness sensor 50 is darker than a preset brightness threshold. Is detected (when a human body detection signal is generated), the operation of turning on the lighting load L, and the time during which the lighting load L is turned on (this time is referred to as the operation holding time) is determined by the timer means configured by the control unit 65. Timed.

  As the operation mode of the control unit 65, a first control mode in which the lighting load L is controlled to be turned on when the heat ray sensor 5 detects a heat ray, regardless of whether or not the heat ray sensor 5 detects the heat ray. Second control mode for controlling the illumination load L to continue, when the illumination load L is turned off, the illumination load L is lit until the operation holding time T1 elapses, and when the illumination load L is turned on There is a third control mode in which the load L is turned off until the operation holding time T1 elapses.

  When the operation element 610 of the operation switch 61 is pressed by the operation handle 3 for a predetermined time (for example, 3 seconds) T2 or more, the control unit 65 switches the lighting load L between lighting and extinguishing. And switch to the second control mode. Further, in the first control mode or the second control mode, when the operation element 610 of the operation switch 61 is pressed by the operation handle 3 for less than the predetermined time T2 in the first control mode or the second control mode, the control unit 65 The second control mode is switched to the third control mode, and when the predetermined time T2 has elapsed, the first control mode is switched (see FIG. 5).

First, when the heat ray sensor 5 detects a heat ray at time t1, the illumination load L is turned on until the operation holding time T1 elapses. After the operation holding time T1 elapses and the illumination load L is turned off, the right side of the handle cover 4 (operation handle 3) is shorter than the predetermined time T2 with the handle cover 4 closed at time t2 (t3-t2). When the operation handle 3 is pushed only, the operation handle 3 rotates, the operation element 610 of the operation switch 61 is pressed on the back surface of the operation handle 3, and an operation signal from the operation switch 61 is input to the control unit 65. At this time, since the illumination load L is off, the control unit 65 turns on the opening / closing element 651 via the driving unit 650 to supply power to the illumination load L, and the illumination load L is operated until the operation holding time T1 elapses. Lights up ("Auto ON" in FIG. 6). After the operation holding time T1 elapses and the illumination load L is turned off, the illumination load L is turned on when the operation handle 3 is pushed again at time t4 for a time shorter than the predetermined time T2 (t5-t4). After that, when the operation handle 3 is pushed at time t6 for a time longer than the predetermined time T2 (t7-t6), the illumination load L is turned off (“forced OFF” in FIG. 6). While the lighting load L is extinguished by being pushed for a time longer than the predetermined time T2 (t7-t6), the lighting load L is kept off even if the hot wire sensor 5 detects the heat ray at time t8. Thereafter, when the operation handle 3 is pushed at time t9 for a time shorter than the predetermined time T2 (t10-t9), the illumination load L is turned on until the operation holding time T1 elapses (“automatic ON” in FIG. 6). Thereafter, the illumination load L is turned off, and when the heat ray sensor 5 detects the heat ray at time t11, the illumination load L is turned on until the operation holding time T1 elapses.

  Subsequently, FIG. 7B will be described. When the lighting load L is turned on, the lighting load L is turned off when the operation handle 3 is pushed at time t21 for a time shorter than the predetermined time T2 (t22-t21) ("automatic OFF" in FIG. 6). . Thereafter, when the operation handle 3 is pushed at a time t23 for a time shorter than the predetermined time T2 (t24-t23), the illumination load L is turned on until the operation holding time T1 elapses (“automatic ON” in FIG. 6). . After the illumination load L is extinguished, when the operation handle 3 is pushed at time t25 for a time (t26-t25) longer than the predetermined time T2, the illumination load L is continuously lit (“forced ON” in FIG. 6). ). Thereafter, when the operation handle 3 is pushed at time t27 for a time shorter than the predetermined time T2 (t28-y27), the illumination load L is turned off (“automatic OFF” in FIG. 6). Thereafter, when the heat ray sensor 5 detects the heat ray at time t29, the illumination load L is turned on until the operation holding time T1 elapses.

  Finally, FIG. 7C will be described. If the operation handle 3 is pushed at a time 31 longer than the predetermined time T1 (t32-t31) while the illumination load L is turned on, the illumination load L is turned off (“forced OFF” in FIG. 6). ). While the illumination load L is extinguished, the illumination load L continues to be extinguished even when the hot wire sensor 5 detects the thermal ray at time t33. After that, when the operation handle 3 is pushed at time t34 for a time longer than the predetermined time T2 (t35-t34), the illumination load L is continuously turned on ("forced ON" in FIG. 6).

  Next, the automatic switch 1 with a heat ray sensor of Embodiment 1 and the automatic switch 1a with a heat ray sensor according to the first comparative example shown in FIG. 9 will be compared. The automatic switch with heat ray sensor 1a is provided with a changeover switch 80 for switching on and off the illumination load L continuously. As with the automatic switch with heat ray sensor 1, the operation handle 3 is pushed and switched for a time longer than a predetermined time T2. It is not a thing. As shown in FIG. 10, the changeover switch 80 is provided so as to be able to be switched in the order of “OFF”, “AUTO”, and “CONTINUOUS ON”.

  Next, an automatic switch with a heat ray sensor according to a second comparative example, which has the same appearance as the automatic switch 1 with a heat ray sensor of the first embodiment but has a different means for switching on and off the illumination load L, will be described. As shown in FIG. 11, the automatic switch with a heat ray sensor of the second comparative example has an operation holding time setting unit 62 a in “OFF” for turning off the lighting load L and “continuous” for turning on the lighting load L continuously. "On". In the automatic switch with a heat ray sensor of the second comparative example, in order to continuously turn on and off the illumination load L, the handle cover 4 must be opened and the operation holding time setting unit 62a must be operated. As described above, the operation handle 3 is not switched by being pushed in a time longer than the predetermined time T2.

  As described above, according to the first embodiment, whether or not the lighting load L is switched on and off regardless of whether or not the detection by the heat ray sensor 5 is continued and the switched state is continued for a long time can be easily and erroneously performed by pressing the operation handle 3. Can be switched.

  Further, even when the heat ray sensor 5 is in an effective time, the lighting load L can be temporarily turned on when the lighting load L is turned off by a short pressing operation on the operation handle 3, and the lighting load L is Since the light can be temporarily turned off when the light is on, wasteful power supply to the illumination load L can be reduced.
