(2.2) Structure Next, the structure and operation of each part of the load control device 1 will be described.

(2.2.1) Body section The body section 2 includes a switch body 4 and a switch panel 5.

The switch body 4 includes a box-shaped body 41. The main body 41 includes a rear body 42 and a front cover 43. The body 42 and the cover 43 are molded articles of synthetic resin, respectively. The main body 41 is formed by combining the main body 42 and the cover 43.

A pair of assembling claws 45 are provided on the cover 43 at the upper and lower sides of the left side, and a pair of assembling claws 45 are provided at the central part in the up and down direction of the right side. To the mounting frame 8; the mounting frame 8 is used to fix the embedded wiring device on the construction surface. Thereby, the switch body 4 can be mounted on the mounting frame 8 by engaging the assembly claws 45 with the assembly holes 81 of the mounting frame 8, and the switch body 4 can be fixed to the wall surface by using the mounting frame 8. And other construction surfaces 100 (see FIG. 3). A cover plate 9 is mounted on the front surface of the mounting frame 8, and the front surface of the load control device 1 (for example, the front surface of the switch panel 5 or the transmitter 3) is exposed through the opening portion 91 of the cover plate 9.

The movable lever 44 is provided on the front surface of the cover 43 on the right side of the central portion in the vertical direction. A front surface of the cover 43 is connected to the right side of the movable rod 44, and a penetrating portion is provided, and a display portion 47 is disposed in the penetrating portion. The display portion 47 is constituted by a light-transmitting lens formed of a transparent synthetic resin (for example, acrylic resin). The shape of the front surface of the display portion 47 is an elliptical shape having a long vertical direction. In addition, the display portion 47 only needs to be translucent, and may be a translucent translucent member or a colored translucent member. The display portion 47 is not limited to a synthetic resin, and may be formed of glass or the like.

A shaft portion 46 is provided on the front surface of the cover 43 at the left end of the central portion in the vertical direction, and supports the switch panel 5 in a rotatable state. An elastic piece 48 for pushing the switch panel 5 forward is integrally provided at the upper and lower portions of the front face of the cover 43.

A through hole 49 is provided on the lower side of the shaft portion 46 in front of the cover 43. The through hole 49 penetrates the front wall of the cover 43 in the front-rear direction. Inside the main body 41, a photodiode of the body-side communication portion 62 is disposed, and faces the through-hole 49.

The switch panel 5 is formed of a synthetic resin, and has a rectangular shape when viewed from the front. A bearing portion 51 is provided on the rear surface of the left side portion of the switch panel 5, and a shaft portion 46 is supported in a rotatable state (see FIG. 2). A protrusion 52 is provided on the back surface of the switch panel 5 at a portion facing the movable lever 44. In a state where the switch panel 5 is assembled to the main body 41, the switch panel 5 can be rotated about the shaft portion 46 as a center.

At the switch panel 5, at one end (the right side) opposite to the support side of the shaft portion 46, if the user presses the switch panel 5, the switch panel 5 rotates around the shaft portion 46 as a center. When the movable lever 44 is pressed by the protrusion 52 of the switch panel 5 as the switch panel 5 rotates, the on / off of the button switch built into the main body 41 changes. After that, when the user's hand leaves the switch panel 5 and loses the force to press the switch panel 5, the switch panel 5 will bear the elastic force of the elastic piece 48 and move forward. As a result, the movable lever 44 returns to its original position, and the on / off of the button switch built into the main body 41 changes.

A projection 53 is formed on the left end of the front of the switch panel 5 so as to protrude toward the front side. The projection portion 53 is provided at a portion corresponding to the through hole 49 of the cover 43 with a penetration portion 55 (see FIG. 2) penetrating the projection portion 53 in the front-rear direction. A light receiving cover 54 having an elongated, elongated plate shape is attached to the projection portion 53 in the vertical direction. The light-receiving cover 54 is formed of a synthetic resin that is transparent to infrared rays and light-shielding to visible light. The light-receiving cover 54 covers the penetration portion 55. Therefore, the main body side communication unit 62 can receive the optical signal (control signal) sent from the transmitter 3, and when viewed from the outside, the main body side communication unit 62 can be made unobtrusive. Furthermore, protrusions 531 are provided on the upper and lower sides of the right side surface of the projection portion 53, respectively.

On the right side of the front face of the switch panel 5, a through hole 56 penetrating the switch panel 5 in the front-rear direction is provided at a portion facing the display portion 47 of the main body 41. A translucent lens 57 (body-side light guide portion) is mounted on the back of the switch panel 5. The light-transmitting lens 57 is formed of a molded product of a transparent synthetic resin (for example, acrylic resin or the like). The light-transmitting lens 57 includes an elliptical protrusion 571, and the shape of the protrusion 571 is long when viewed from the front. The light-transmitting lens 57 is fixed to the back surface of the switch panel 5 in a state where the protruding portion 571 is inserted into the through-hole 56. Thereby, in a state where the switch panel 5 is mounted on the main body 41, the light emitted from the display portion 47 is irradiated to the front side through the light transmitting lens 57. That is, the switch panel 5 as the movable portion includes a light transmitting lens 57 (body-side light guide portion), and guides light from the display portion 47 to the light guide portion 35. Therefore, by providing the light-transmitting lens 57 on the switch panel 5, the display portion 47 can be provided on the switch body 4; the structure of the switch panel 5 can be simplified compared with the case where the display portion 47 is provided on the switch panel 5.

Furthermore, in this embodiment, the switch panel 5 serving as a movable portion has one end (left end) in a certain direction (the short side direction of the switch panel 5 in this embodiment is a direction parallel to the horizontal direction). It is rotatably supported with respect to the switch body 4 as a fixed portion. Then, the switch panel 5 is at the other end (right end) in the above direction, and has a light-transmitting lens 57 as a body-side light guide portion. Thereby, the light of the display portion 47 is output through the light-transmitting lens 57 which is located at one end opposite to the one end rotatably supported by the switch panel 5. Therefore, the user can determine the end on which the switch panel 5 is pressed based on the light output through the light transmitting lens 57 or the light guide 35.

In addition, the body-side light guide portion is not limited to a transparent light-transmitting lens 57, and may be a translucent light-transmitting member, or may be a colored light-transmitting member. In addition, the main-body-side light guide is not limited to a synthetic resin transparent lens 57 and may be formed of glass or the like.

Further, an iron piece 58 (attracted member) is attached to the back of the right side of the switch panel 5 and is attracted by the magnetic force of the magnet 34 (see FIG. 6) built in the transmitter 3. Since the transmitter 3 has a magnet 34, the transmitter 3 can also be used by being mounted on a portion formed by a ferromagnetic body such as iron.

In the present embodiment, although the attracted member made of an iron piece is attached to the switch panel 5, the attracted member is not limited to an iron member, and may be a ferromagnetic metal such as iron or the like. Its alloys are formed.

(2.2.2) Transmitter Next, the configuration of the transmitter 3 will be described with reference to FIGS. 1 to 3 and 5 to 7.

The transmitter 3 includes a transmitter body 30 made of a synthetic resin molded article. The transmitter 3 is attachable and detachable to a switch panel 5 as a movable portion. By holding the transmitter 3 on the switch panel 5, the size of the front face of the load control device 1 can be reduced compared to a case where the transmitter 3 is held on a portion other than the switch panel 5.

The transmitter body 30 is formed in a flat rectangular parallelepiped shape, and an opening 301 is provided on the rear surface of the transmitter body 30. The shape and size of the front surface of the transmitter body 30 are formed to be almost the same as the shape and size of the portion except the projection 53 in the front surface of the switch panel 5. A battery such as a printed circuit board 32 (refer to FIGS. 6 and 7) and a button battery is housed inside the transmitter body 30 as a power source for a circuit formed on the printed circuit board 32. On the printed circuit board 32, circuits such as a transmitter-side communication section 71, an operation receiving section 72, a transmitter-side control section 73, and the like are formed. The light-emitting diode of the transmitter-side communication portion 71 is mounted on the upper portion of the printed circuit board 32; a through-hole 303 is provided on the upper side of the transmitter body 30 to expose the light-emitting diode. The printed circuit board 32 is fixed to the transmitter body 30 using, for example, a flat head screw. Therefore, since the step difference between the surface of the printed substrate 32 and the head of the grub screw can be reduced, it has the advantage that the distance between the diaphragm (MEMBRANE SHEET) 33 disposed on the rear side of the printed substrate 32 and the printed substrate 32 can be reduced. gap.

A diaphragm 33 is adhered to the rear of the transmitter body 30, and the opening 33 of the rear of the transmitter body 30 is covered by the diaphragm 33. The diaphragm 33 is formed in a plate shape from a transparent synthetic resin and has flexibility.

In the film 33, the light-transmitting area 332 is transparent, and the light-transmitting area 332 corresponds to the protruding portion 571 of the light-transmitting lens 57 of the switch panel 5. Moreover, all parts of the film 33 except for the light-transmitting area 332 are white. Therefore, the inside of the transmitter body 30 can be hidden by the diaphragm 33.

On the surface of the diaphragm 33, five operating portions 331 protruding in a dome shape are provided. A circular movable contact is formed on the diaphragm 33, and the conductive ink is applied to the back surfaces of the five operation portions 331, respectively. On the other hand, on the printed circuit board 32, portions corresponding to the five operation portions 331 are printed by, for example, carbon paste to form a pair of fixed contacts. Here, the switch is constituted by a pair of fixed contacts and movable contacts.

When the user presses the operation portion 331 and the movable contact formed on the back side of the operation portion 331 contacts a pair of fixed contacts, the pair of fixed contacts are electrically connected via the movable contact, so Turn on the switch. On the other hand, when the operation portion 331 is not pressed, the pair of fixed contacts is electrically opened, and the switch is turned off. The operation receiving section 72 of the transmitter 3 monitors the on / off states of the five switches. When the switches are turned on, an operation signal is output to the transmitter-side control section 73. When the transmitter-side control unit 73 receives an operation signal from the operation receiving unit 72, it sends a control signal corresponding to the user's operation to the switch body 4 from the transmitter-side communication unit 71. As such, since in this embodiment, a pair of fixed contacts formed on the printed circuit board 32 and movable contacts formed on the diaphragm 33 constitute a switch, the existing switch is used in comparison with the use of a touch switch and the like. In the case of a switch, the thickness of the transmitter 3 can be further reduced.

In addition, a decorative plate 31 is installed in front of the transmitter body 30 by bonding, ultrasonic welding, or the like. The decorative plate 31 is made of a translucent synthetic resin (such as an acrylic resin or the like). form. The transmitter body 30 is provided with a through hole 303 penetrating the transmitter body 30 in the front-rear direction at a portion corresponding to the protruding portion 571 of the switch panel 5. The rear surface of the decorative plate 31 is integrally provided with a lens portion 312 inserted into the through hole 303. The lens portion 312 has a columnar shape, is formed in an oval shape when viewed from the rear, and projects from the rear surface of the decorative plate 31 toward the rear. In addition, on the front surface of the decorative plate 31, a protruding portion 311 protruding forward is provided at a portion corresponding to the lens portion 312. Here, the light guide section 35 is constituted by the lens section 312 and the protruding section 311, and the light from the display section 47 is guided to the front side of the transmitter 3. The light guide 35 guides light from the rear side of the transmitter 3 to the front side, and can output the light incident on the rear side of the transmitter 3 from the front side.

In this embodiment, the decorative plate 31 constituting the front member of the transmitter 3 and the light guide portion 35 (transmitter-side light guide portion) are integrally formed. Since the light guide 35 is fixed to the transmitter body 30 by fixing the decorative plate 31 to the transmitter body 30, there is no need to provide the transmitter body 30 with the light guide 35 to be fixed to the transmitter body. The structure of 30 can increase the free space inside the transmitter body 30. Furthermore, by integrating the decorative plate 31 and the light guide portion 35 into one piece, the light loss between the decorative plate 31 and the light guide portion 35 can be reduced. Therefore, it is possible to increase the amount of light rays output to the front side of the transmitter 3 via the light guide section 35.

In addition, although a surface treatment is performed in front of the protruding portion 311 to uniformly emit light, such a surface treatment is not necessary. As long as the light guide portion 35 can guide light from the rear side of the transmitter 3 to the front side, its shape can be appropriately changed.

The decorative plate 31 according to this embodiment is manufactured by a technique such as two-color molding. For example, since the lens portion 312 is initially formed, and then a plate-like portion is formed at one end of the lens portion 312, the decorative plate 31 can be integrally formed.

A magnet 34 is housed inside the transmitter body 30 at a position corresponding to the iron piece 58 assembled on the switch panel 5. The magnet 34 is a rare earth magnet such as a neodymium magnet or a cobalt magnet. The transmitter body 30 is provided with a storage recess 304 for storing the magnet 34. In the transmitter body 30, a protrusion provided on a side wall of the receiving recessed portion 304 is deformed by thermal energy or the like to form an engaging portion 305. By pressing one end of the magnet 34 with the engaging portion 305, the magnet 34 is fixed to the transmitter body 30.

Furthermore, grooves 302 are provided on the upper and lower portions of the left side of the transmitter body 30, so that the protrusions 531 provided on the projection portion 53 of the switch panel 5 can be inserted (see FIG. 2).

In this embodiment, the lens portion 312 is provided integrally with the decorative plate 31. When the lens portion 312 is different from the decoration plate 31, a structure for fixing the lens portion 312 to the transmitter body 30 is required; however, in this embodiment, the lens portion 312 and the decoration plate 31 are Since it is integrated, there is no need for a structure for fixing the lens portion 312 to the transmitter body 30. Thereby, a space for accommodating the magnet 34 can be secured inside the transmitter body 30. In the present embodiment, the magnet 34 is built in the transmitter 3. Therefore, the transmitter 3 can be installed on an iron appliance such as a refrigerator or a desk, and the convenience of use of the transmitter 3 can be improved.

(2.2.3) How to use the load control device The load control device 1 of this embodiment is fixed to the construction surface 100 and used. The switch body 4 is fixed to the construction surface 100 using a mounting frame 8, and a cover plate 9 is mounted on the front side of the mounting frame 8. A switch panel 5 is mounted on the switch body 4 in a rotatable state. A transmitter 3 is mounted on the switch panel 5. The transmitter 3 is mounted on the switch panel 5 in a state that the groove 302 on the left side of the transmitter body 30 is aligned with the protrusion 531 of the switch panel 5 and is held on the switch panel 5 by the magnet 34 .

In the state where the transmitter 3 is installed on the switch panel 5, if the right side of the transmitter 3 is pressed, the switch panel 5 will rotate with the transmitter 3 and press the movable lever 44 with the protrusion 52 of the switch panel 5, and then move The back of the lever 44 presses the button switch stored in the main body 41. Thereby, the on / off of the buck switch is changed, and the main body side control section 65 controls the on / off of the semiconductor switch 61 so that the load L1 is turned on or off.

Here, the body-side control unit 65 lights the light-emitting unit 64 when the load L1 is turned off, for example, and outputs the light from the light-emitting unit 64 from the display unit 47 to the front side. Since the transmitter 3 mounted on the switch panel 5 is provided with the light guide portion 35, the light output from the display portion 47 to the front side is guided to the light transmitting portion 57 and the light guide portion 35 of the switch panel 5 to The front side of the transmitter 3 is irradiated from the protrusion 311 to the front of the transmitter 3. Therefore, the user can confirm the light of the display portion 47 (light emitting portion 64) through the protruding portion 311 (light guide portion 35) of the transmitter 3, and the display of the display portion 47 can be confirmed.
