Here, the mounting frame 7 will be described. The mounting frame 7 is a series in which three embedded wiring mechanisms having standardized unit module dimensions (one module dimension) can be mounted side by side in the long side direction (Z-axis direction in FIG. 1). In each of the two side pieces 71 and 71 surrounding the window hole 70 of the mounting frame 7, three pairs of mechanism mounting holes 72 ... for mounting the wiring mechanism are formed. By attaching the mounting claw 214 of the cover 21 to such a mechanism mounting hole 72..., The base 2 is fixed to the mounting frame 7. When attaching the base 2 to the mounting frame 7, the mounting claw (not shown) provided on the left wall of the cover 21 is inserted into the mechanism mounting hole 72 of the mounting frame 7, and the right side is inserted. If the mounting claws 214 and 214 provided in the wall 213 are retracted from the side surface of the cover 21, and the front portion of the base 2 is inserted into the window hole 70 of the mounting frame 7, the right wall Mounting claws 214 and 214 of 213 are inserted into the instrument mounting holes 72 so that the base 2 is held in the mounting frame 7.

It can be pulled out and the base 2 can be isolate | separated from the mounting frame 7.

Moreover, each of the upper and lower frame pieces 73 and 73 of the mounting frame 7 is provided with one long hole 74 and 74 for penetrating the box screws 740 and 740. The box frame 740 inserted through each of the long holes 74 is screwed into a screw portion (not shown) of a buried box embedded in an imaging surface such as a wall surface, so that the mounting frame 7 is made of a contrast material (not shown). And the rear part of the base 2 held by the mounting frame 7 is embedded in the contrast medium. Further, each frame piece 73 is provided with a pair of screw holes 75... For plate screws. The mounting frame 7 is screwed on the front face side using a plate frame (not shown) and a plate screw (not shown) formed in a rectangular frame shape by a synthetic resin. The makeup plate 76 is detachably attached to the front face side of this plate frame. The plate frame and the makeup plate 76 are each formed with a window hole 760 that is longer and wider than the window hole 70 of the mounting frame 7, and has a hot wire sensor through the window hole 760. The front face of the automatic switch 1 is exposed.

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. Moreover, the front surface of the cover 21 is provided with the protrusion 223 which protrudes forward. An opening 226 is formed in the front surface of the protrusion 223. Half-moon-shaped protrusions 227 and 228 are provided above and below the opening 226.

In addition, the cover 21 includes a pair of shaft portions 231 and 231 integrally provided to protrude forward from the left end of the front face 230 in order to pivotally mount the operation handle 3. The front end part of each shaft part 231 is formed in the column shape along the long side direction of the cover 21. As shown in FIG.

The left and right directions of the operation handle 3 are substantially the same as the left and right direction (short side direction) of the window hole 760 of the makeup plate 76, and the up and down direction is the up and down direction (long side of the window hole 760). It is formed in the shape of a rectangular plate by synthetic resin so that it may become a dimension of almost two thirds of directions). This operation handle 3 is provided with the bearing part (not shown) provided in the back surface of the left part 30. As shown in FIG. The bearing part pivotally supports the shaft portions 231 and 231 of the cover 21 so that the operation handle 3 covers the upper half of the front surface 230 of the body 2. It is pivotally supported on the side 230.

Moreover, the operation handle 3 is equipped with the pressing protrusion 31 provided in the site | part which opposes the operator 610 mentioned later exposed to the front surface 230 of the cover 21 on the back surface. When the right part 32 of the operation handle 3 is pushed in operation, the operation handle 3 rotates with the shaft parts 231 and 231 as the point, and is pressed against the pressing projection 31 of the operation handle 3. By this, the operator 610 is pressed and the operation switch 61 is turned on. On the other hand, when the pressing force is removed from the operation handle 3, the operation handle 3 returns to the return position in response to the reaction force of the operator 610, and the operation switch 61 is turned off. Moreover, since the operation handle 3 makes surface contact with the front surface of the mounting frame 7 by the left edge pivotally supported by the shaft parts 231 and 231, even if the left handle 30 of the operation handle 3 is pressed down, , The operation handle 3 can be prevented from inclining.

Moreover, the operation handle 3 has a thin part 33, and the operation | movement mentioned later to the site | part corresponding to the window hole 220, 221 of the cover 21 in this thin part 33 is carried out. Opening window 34 at a portion facing the operation holding time setting part 62 and the brightness sensor adjusting part 63 so as to penetrate the holding time setting part (setting operation part) 62 and the brightness sensor adjusting part 63, respectively. , 35) are formed. Moreover, in the operation handle 3, the perforation hole 36 in which the light guide member (not shown) is inserted is formed in the substantially center part in the up-down direction (Z-axis direction of FIG. 1) of the left part 30. It is. The light guide member is formed of a synthetic resin having light transmittance and is attached to the back side of the operation handle 3 in a state of being fitted into the transmission hole 36. Thereby, the irradiation light of the light emitting diode LD accommodated in the base | substrate 2 is radiate | emitted forward from the transmission hole 36 of the operation handle 3 via the light guide member hold | maintained at the operation handle 3.

The light emitting diode LD displays an operation mode according to, for example, color or lighting state. For example, in the case of the display by color, the lighting load L is lit red continuously, the lamp is lit green when auto lit, and the light load L is unlit. On the other hand, in the case of the display by the lighting state, for example, when the lighting load L is continuously lighted, it lights continuously, it flashes when it is automatic lighting, and turns off when the light load L is forcibly turned off.

While the operation handle 3 is mounted on the upper side of the cover 21, the makeup cover 37 is attached to the lower side of the cover 21. In the makeup cover 37, a through insertion hole 370 is formed at a position opposite to the center of the cover insertion hole 225 in the left and right direction (Y-axis direction in FIG. 1), and the opening ( An opening 371 is formed at a position opposite to 226.

The handle cover 4 is pivotally mounted on the front surface of the operation handle 3 so as to cover the thin portion 33 of the operation handle 3. The dimension of the left-right direction and up-down direction of the handle cover 4 is substantially the same as the left-right direction and the up-down direction of the thin part 33, respectively. Moreover, the arms 40 and 40 which protrude laterally are provided from the upper and lower ends of the side part of the handle cover 4, and the shaft provided in the upper and lower sides of the operation handle 3 in the front-end | tip part of each arm 40 is provided. The pivot shafts 41 and 41 which are pivotally supported by the hole 38 protrude. By pivotally supporting the pivot shaft 41 of the arm 40 in the shaft hole 38 of the operating handle 3 in this way, the handle cover 4 exposes the opening windows 34 and 35 and the opening window. It is rotatably mounted on the front face of the operation handle 3 so as to select a position covering the 34 and 35. By using such a handle cover 4, since most of the thin part 33 can be hidden when the handle cover 4 is closed, a neat design can be achieved.

The heat ray sensor 5 is provided with sensor elements, such as a superconducting element, and detects the heat ray from a human body which exists in the preset area | region, and is mounted in the circuit board 60 of the circuit part 6 mentioned later. This heat ray sensor 5 is integrally comprised with the brightness sensor 50, such as CdS and a photodiode, for example, and it is also possible to distinguish the surrounding brightness by this brightness sensor 50. FIG.

The hot wire sensor 5 covers the front surface side with the sensor cover 51. The sensor cover 51 is provided with a detection window 510 for exposing the hot wire sensor 5. Through this detection window 510, the heating wire sensor 5 detects a heating wire from the human body from the outside. The sensor cover 51 is accommodated in the base 2 so as to be sandwiched between the cover 21 and the circuit portion 6.

A pair of shutters 52 and 52 are provided between the sensor cover 51 and the cover 21. Each shutter 52 is integrally provided with the half-moon-shaped base 520 and the handle part 521 extended at an angle from one end of the base 520. 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 hot wire sensor 5. That is, the base 520 is moved by the operation using the handle part 521 by a 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, optimization of the detection area can be performed.

The circuit part 6 is an operation switch 61 which has a circuit board 60, such as a printed wiring board, the operator 610 which is push-driven by the operation handle 3, and the illumination load L (refer FIG. 2). The operation holding time setting part 62 for setting the lighting time of (), and the brightness sensor adjustment part 63 for setting the brightness detection level of the brightness sensor 50 are accommodated in the base body 2. The heat sink 64 is provided in the back surface side of this circuit part 6.

The operator 610 of the operation switch 61 is exposed to the front surface 230 of the base 2 and is push driven by the operation handle 3.

The operation holding time setting part 62 is a rotary switch etc., for example, and is provided in the front surface 230 of the base 2, and sets operation holding time T1 by user's operation. As shown in Fig. 3, the operation holding time can be set within a range of 10 seconds to 30 minutes. Thereby, optimization of the lighting time of illumination load L can be aimed at. In addition, the brightness sensor adjustment part 63 is a rotary switch etc., for example, and the brightness detection level of the brightness sensor 50 is changed from "dark" (for example, 5Lx or less) to "bright" (for example, 100Lx or more) by user's operation. It is set in the range of. In addition, when it is set to "OFF", the function of the brightness sensor 50 is stopped. As a result, it is possible to prevent the lighting load L2 of the home from being turned on when the surroundings are bright, and energy saving can be achieved.

Here, the circuit structure of the circuit part 6 is demonstrated using FIG. The circuit part 6 inputs the output from the heat ray sensor 5 and the brightness sensor 50 to the control part (microcomputer) 65. As shown in FIG. The control part 65 A / D-converts the output of the hot wire sensor 5 and the brightness sensor 50, and further judges the presence or absence of a person in the preset detection area based on the output value of the hot wire sensor 5. When the inside of the control part 65 determines that a person exists in a detection area based on the output of the heat ray sensor 5, a human body detection signal is generated.

The control part 65 has a function which turns on / off the switching element 651, such as a triac, via the drive part 650. FIG. The switching element 651 is connected between a power supply terminal 652 for connecting a commercial power supply (AC) and a load terminal 655 for connecting an illumination load (L), and the conduction angle is controlled by the control unit 65. ) Is controlled to adjust the power supply to the lighting load L, thereby lighting the lighting load L by the desired light output. The power supply terminals 652 and 653 are connected to a DC stabilized power supply 656 that receives a commercial power source AC and generates a DC constant voltage, and the operating power is supplied to the internal circuit by the DC stabilized power supply 656.

The basic operation of the control unit 65 detects a person 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 threshold value of the preset brightness ( When the human body detection signal is generated), the lighting load L is turned on, and the time when the lighting load L is turned on (this time is referred to as "operation holding time") is a timer configured by the controller 65. Limited by means.

As the operation mode of the control unit 65, the first control mode in which the lighting load L is turned on when the hot wire sensor 5 detects the hot wire, regardless of whether or not the hot wire is detected by the hot wire sensor 5 , The second control mode for controlling the switched state so that the lighting load L continues, when the lighting load L is turned off, the lighting load L is turned on until the operation holding time T1 elapses, There is a third control mode in which the lighting load L is turned off until the operation holding time T1 elapses when the lighting load L is turned on.

When the operator 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 first control mode to the illumination load ( L) is switched on and off to switch to the second control mode. In addition, when the operator 610 of the operation switch 61 is pressed by the operation handle 3 for less than the said fixed time T2 in the 1st control mode or the 2nd control mode, the control part 65 will be made. The first control mode or the second control mode is switched to the third control mode, and when the predetermined time T2 elapses, the control mode is switched to the first control mode (see FIG. 5).

Next, the operation of the automatic switch 1 having the heat ray sensor according to the first embodiment will be described with reference to FIGS. 6 and 7. First, Fig. 7 (a) will be described. First, when the hot wire sensor 5 detects the hot wire at time t1, the lighting load L is turned on until the operation holding time T1 elapses. After the operation holding time T1 has elapsed and the lighting load L is turned off, the right side of the handle cover 4 (operation handle 3) is closed for a predetermined time (with the handle cover 4 closed at time t2). When the operation is pushed for a shorter time (t3-t2) than T2, the operation handle 3 is rotated, and the operator 610 of the operation switch 61 is pressed by the rear surface of the operation handle 3, and the operation switch ( The operation signal from 61 is input to the control unit 65. At this time, since the illumination load L is turned off, the control part 65 turns on the switching element 651 via the drive part 650, supplies electric power to the illumination load L, and supplies the illumination load L to it. The lamp is turned on until the operation holding time T1 elapses (“Auto On” in FIG. 6). After the operation holding time T1 has elapsed and the lighting load L is turned off, the operation handle 3 is pressed again for a shorter time t5-t4 than the predetermined time T2 at the time t4. )). Thereafter, when the operation handle 3 is pressed and operated for a time t7-t6 longer than the predetermined time T2 at the time t6, the illumination load L is turned off ("forced off" in Fig. 6). While the lighting load L is turned off by being pressed for a time longer than the predetermined time T2 (t7-t6), the lighting load L is turned off even if the heating wire sensor 5 detects the heating wire at time t8. Continue. After that, when the operation handle 3 is pressed and operated for a shorter time t10-t9 than the predetermined time T2 at time t9, the lighting load L is turned on until the operation holding time T1 elapses (Fig. "Auto on" of 6). After that, when the lighting load L turns off and the heating wire sensor 5 detects the heating wire at time t11, the lighting load L is turned on until the operation holding time T1 elapses.

Subsequently, Fig. 7 (b) will be described. When the lighting load L is turned on, if the operation handle 3 is operated by a time t22-t21 shorter than a predetermined time T2 at time t21, the lighting load L is turned off (" Auto off ''). After that, when the operation handle 3 is pressed and operated for a shorter time t24-t23 than the predetermined time T2 at time t23, the illumination load L is turned on until the operation holding time T1 elapses ( "Auto On" in Fig. 6). After the lighting load L is turned off, when the operation handle 3 is operated by a time t26-t25 longer than a predetermined time T2 at time t25, the lighting load L is continuously turned on (Fig. 6). "Forced on"). After that, when the operation handle 3 is pressed and operated for a shorter time t28-t27 than the predetermined time T2 at time t27, the illumination load L is turned off (“auto-off” in FIG. 6). After that, when the hot wire sensor 5 detects the hot wire at time t29, the illumination load L is turned on until the operation holding time T1 elapses.

Finally, Fig. 7 (c) will be described. When the lighting load L is turned on, if the operation handle 3 is operated for a time t32-t31 longer than the predetermined time T1 at time t31, the lighting load L is turned off (Fig. 6). `` Forced off ''). While the lighting load L is extinguished, even if the heating wire sensor 5 detects the heating wire at time t33, the lighting load L is extinguished. After that, when the operation handle 3 is pressed and operated for a time longer than the predetermined time T2 (t35-t34) at time t34, the illumination load L is continuously turned on (“forced on” in FIG. 6).

Next, the automatic switch 1 having the hot wire sensor of Embodiment 1 is compared with the automatic switch 1a having the hot wire sensor according to the first comparative example shown in FIG. 9. The automatic switch 1a having a hot wire sensor is provided with a switching switch 80 for switching the continuous on / off of the lighting load L, and the operation handle 3 like the automatic switch 1 having a hot wire sensor. Is not switched by pressing for a time longer than the predetermined time T2. As shown in FIG. 10, the changeover switch 80 is provided so that switching is possible in order of "off", "automatic", and "continuous on".

Next, the automatic switch 1 having the hot wire sensor according to the second comparative example differs in appearance from the automatic switch 1 having the hot wire sensor of the first embodiment, but the means for switching continuous on / off of the lighting load L is different. Explain. As shown in FIG. 11, the automatic switch which has a heat ray sensor of a 2nd comparative example is made into the operation holding time setting part 62a, "off" and lighting load L which turn off lighting load L continuously. We offer "continuous on" to turn on continuously. In the automatic switch having the hot wire sensor of the second comparative example, in order to continuously turn on / off the lighting load L, the handle cover 4 must be opened to operate the operation holding time setting unit 62a, and the hot wire sensor Like the automatic switch 1 having the same, the operation handle 3 is not switched by pressing and operating for a longer time than the predetermined time T2.

As described above, according to the first embodiment, it is possible to switch the on / off of the lighting load L and to sustain the switched state for a long time regardless of the presence or absence of the detection by the heat ray sensor 5 to the operation handle 3. By pressing operation, it is easy and malfunction can be reduced and switched.

Moreover, even when the heating wire sensor 5 is effective, even when the lighting load L is extinguished by the short time pressing operation to the operation handle 3, it can turn on temporarily, and the lighting load L lights up. Since it is possible to temporarily turn off the light, the useless power supply to the lighting load L can be reduced.
