[Rear housing]
Next, the rear housing 60 will be described. The rear housing 60 is a substantially rectangular box-shaped member that covers the substrate 20 from the second main surface side and has an open front side. The rear housing 60 is specifically formed of an ABS resin, but may be formed of another resin such as a PBT resin, or may be formed of a metal.

  The overall shape of the rear housing 60 is symmetrical to the front housing 50 and the XY plane, but the rear housing 60 attaches the control device 10 to a structure (for example, a wall). Is different from the front casing 50 in that the rear casing 65a has a mounting structure for the rear panel 65a and a plurality of buttons and the like described above are not arranged. FIG. 6 is a view of the housing 30 as viewed from the rear. FIG. 7 is a diagram for explaining how the control device 10 is attached to a wall. In addition, FIG. 6 is a view of the housing 30 in a state where the metal fitting 80 is attached to the rear surface 65a as viewed from the back in more detail.

  FIGS. 6 and 7 show a substantially flat metal fitting 80 for attaching the control device 10 to the wall 85. In mounting control device 10 on wall 85, first, metal fitting 80 is mounted on wall 85 with screws. Specifically, a metal screw is inserted into the screw insertion hole 81 from the side opposite to the wall 85, so that the metal fitting 80 is screwed to the wall 85.

  Next, the housing 30 is attached to the metal fitting 80. Specifically, an upper end portion 82 bent at the upper end side of the metal fitting 80 and projected forward is fitted into the concave portion 61 provided above the rear surface 65 a of the rear housing 60. In addition, it is provided below the rear surface 65a of the rear housing 60 in the gap between the wall 85 and the mounting portion 83 that is provided at the lower end portion of the metal fitting 80 and protrudes in an arch shape toward the front. The protruding protrusion 62 is inserted from above. Thus, the housing 30 is attached to the wall 85. The concave portion 61 and the convex portion 62 are examples of a mounting structure.

  As shown in FIG. 7, when the control device 10 is mounted without being embedded in the wall 85, the outer surface of the housing 30 becomes visible from the outside, and the front housing 50 and the rear housing 60 are aligned. The eyes (boundaries) are visible to the user from the side, and the appearance is poor. Therefore, the control device 10 includes a decorative cover 40 that covers the front and outer surfaces of the housing 30.

[Cosmetic cover]
Next, the decorative cover 40 will be described with reference to FIGS. 2 and 3 described above. The decorative cover 40 covers the housing 30 from the front. The decorative cover 40 is, specifically, a substantially rectangular parallelepiped box-shaped member that substantially covers all surfaces except the rear surface 65a of the housing 30 and that is open at the rear.

Each of the cover portions is a substantially rectangular flat plate having a size corresponding to the surface to be covered, and is arranged substantially parallel to the surface to be covered.

  The front cover 48 is provided with an opening 47 for exposing the schedule button 71, the light control button 72, the OFF / ON button 73, the display unit 70, and the light emitting unit 75.

[Mounting structure for makeup cover]
The mounting structure of the decorative cover 40 in the control device 10 will be described with reference to FIGS.

  As shown in FIG. 2, on the upper side surface 33 a of the housing 30, the first protrusion 31 is provided on the rear housing 60 along the boundary with the front housing 50. That is, the first projection 31 is disposed at an end of the rear housing 60 that forms the above-described boundary. Here, the boundary means a joint between the front housing 50 and the rear housing 60. In the first embodiment, the boundary line indicating the boundary extends in the X-axis direction, and the first protrusion 31 is a protrusion that is long in the X-axis direction along the boundary line. Used. The cross-sectional shape when the first projection 31 is cut along the YZ plane is a substantially semicircular shape in which a part on the near side is an inclined surface (illustrated in FIG. 10 described later).

  Further, in the first embodiment, the first protrusion 31 is formed integrally with the rear housing 60, but may be formed integrally with the front housing 50. That is, on the upper side surface 33 a of the housing 30, the first protrusion 31 may be provided on the front housing 50 along the boundary with the rear housing 60. In other words, the first protrusion 31 may be disposed at an end of the front housing 50 that forms the boundary.

  In addition, one first protrusion 31 may be formed by combining a protrusion arranged at an end of the rear housing 60 forming the boundary with the protrusion formed with the seam. Note that two first projections 31 are provided at intervals in the X-axis direction, which is a direction intersecting the front-rear direction (Z-axis direction).

  Similarly, as shown in FIG. 3, on the lower surface 35 a of the housing 30, the first protrusion 32 is provided on the rear housing 60 along the boundary with the front housing 50. The first projection 32 is a projection having a long shape in the X-axis direction along the boundary line, and is used for attaching the decorative cover 40. The cross-sectional shape when the first protrusion 32 is cut along the YZ plane is a substantially semicircular shape in which a part on the near side is an inclined surface, like the first protrusion 31.

  The first projection 32 is also formed integrally with the rear housing 60, but may be formed integrally with the front housing 50. That is, on the upper side surface 33 a of the housing 30, the first protrusion 32 may be provided on the front housing 50 along the boundary with the rear housing 60. In other words, the first protrusion 32 may be disposed at an end of the front housing 50 that forms the boundary.

  In addition, one first protrusion 32 may be formed by combining the convex portion provided at the end of the rear housing 60 forming the boundary with the convex portion formed with the seam. The two first protrusions 32 are also provided at intervals in the X-axis direction. The distance between the two first protrusions 31 in the X-axis direction and the distance between the two first protrusions 32 in the X-axis direction are also provided. And different.

  On the other hand, protrusions corresponding to the first protrusion 31 and the first protrusion 32 are provided inside the decorative cover 40. FIG. 8 is a diagram of the inside of the decorative cover 40 viewed from above, and FIG. 9 is a diagram of the inside of the decorative cover 40 viewed from below.

  As shown in FIG. 8, two second protrusions corresponding to the two first protrusions 32 are provided on an inner surface 45 a of the lower surface cover portion 45 facing the lower surface 35 a of the decorative cover 40. 42 are provided. As shown in FIG. 9, of the upper surface cover portion 43 of the decorative cover 40, two inner surfaces 43 a facing the upper surface 33 a correspond to the two first protrusions 31 and have two second protrusions 31. Are provided. The cross-sectional shape when the second protrusion 41 and the second protrusion 42 are cut along the YZ plane is substantially semicircular.

  When attaching the decorative cover 40, the user pushes the decorative cover 40 into the housing 30 from the front. Then, as shown in FIG. 10, the second protrusion 41 gets over the first protrusion 31 and is hooked on the inner side (the Z-axis direction − side) of the first protrusion 31. FIG. 10 is a cross-sectional view showing an engagement portion between the first projection 31 and the second projection 41. FIG. 10 also shows the metal fitting 80, the wall 85, the substrate 20, and the like.

  Similarly, when the user pushes the decorative cover 40 into the housing 30 from the front, the second protrusion 42 gets over the first protrusion 32 and is caught on the inner side of the first protrusion 32.

  Thus, the decorative cover 40 is attached to the housing 30 by the engagement of the first projection and the second projection.

[Effects]
Conventionally, a structure in which a nail of a decorative cover is engaged with a rear surface of a housing is known. However, with such a structure, there are cases where the decorative cover is difficult to remove. For example, in some cases, the decorative cover cannot be removed unless the housing is removed from the wall.

  On the other hand, in the control device 10, the decorative cover 40 is engaged with the first protrusion 31 and the first protrusion 32 provided on the side surface of the housing 30 instead of the rear surface of the housing. For this reason, removal of the decorative cover 40 is easy. For example, the control device 10 is capable of attaching and detaching the decorative cover 40 without removing the housing 30 from the wall, and removing the decorative cover 40 from the structure in which the nail of the decorative cover is engaged with the rear surface of the housing. Is easy.

  In addition, when the housing is composed of the front housing and the rear housing, the boundary between the front housing and the rear housing may have a step due to a variation in manufacturing dimensions of the front housing and the rear housing. There is. In the above-described structure in which the nail of the decorative cover is engaged with the rear surface of the housing, such a step interferes with the inner surface of the decorative cover, and thus it may be difficult to attach and remove the decorative cover.

  On the other hand, in the control device 10, the first protrusion 31 and the first protrusion 32 are provided near the boundary between the front case 50 and the rear case 60, and the size of the decorative cover 40 is the first size. It is determined in consideration of the protrusion of the projection 31 and the first projection 32. For this reason, the above-mentioned steps are prevented from interfering with the inner surface 43a of the decorative cover 40, and attachment and detachment of the decorative cover 40 are facilitated.

  Further, as shown in FIG. 2, a groove 31 a having a width corresponding to the second protrusion 41 and extending in the front-rear direction (Z-axis direction) is provided on the upper side surface 33 a of the housing 30. The groove portion 31a is a portion that is recessed downward (inside of the housing 30) on the upper side surface 33a of the housing 30, and the first protrusion 31 is formed between the front housing 50 and the rear side of the groove portion 31a. It is provided near the boundary with the housing 60.

  Thereby, the interference between the second protrusion 41 and the upper side surface 33a is suppressed, so that attachment and detachment of the decorative cover 40 can be further facilitated. The groove 31a also functions as a guide for the second protrusion 41. As shown in FIG. 3, the first protrusion 32 is also provided near the boundary between the front housing 50 and the rear housing 60 in the groove 32a of the lower surface 35a.

  Further, the front housing 50 and the rear housing 60 are specifically formed by injection molding using a mold. When the first projection 31 is disposed at the end of the rear housing 60 forming the boundary as in the control device 10, the first projection 31 is molded at the end of the mold of the rear housing 60. Since the rear housing 60 can be easily removed from the mold, injection molding of the rear housing 60 is facilitated. The same applies to the case where the first protrusion 31 is arranged at the end of the front housing 50 forming the boundary, and the injection molding of the front housing 50 is facilitated.

  In addition, as shown in FIG. 11, the upper side surface 33a is inclined in the front-rear direction (Z-axis direction) so as to be located outward (Y-axis direction + side) as approaching the boundary portion. FIG. 11 is a cross-sectional view for explaining the inclination of the upper side surface 33a. As illustrated in FIG. 11, on the back side of the first protrusion 31, the upper side surface 33 a is inclined by θ1, and on the front side of the first protrusion 31, the upper side surface 33 a is only θ2. It is inclined. The groove 31a is also inclined. Although not shown in detail, the lower side surface 35a is also inclined in the front-rear direction (Z-axis direction) such that the lower side surface 35a is positioned more outward (Y-axis direction-side) as approaching the boundary portion. The same applies to the groove 32a provided.

  Accordingly, when the decorative cover 40 is removed, when the second protrusion 41 gets over the first protrusion 31 toward the near side, the second protrusion 41 and the upper side surface 33a (the groove 31a) become closer as the decorative cover 40 comes to the near side. Gap becomes large. Similarly, when the second protrusion 42 gets over the first protrusion 32 toward the near side, the gap between the second protrusion 42 and the lower side surface 35a (the groove 32a) increases as the decorative cover 40 comes closer to the near side. For this reason, removal of the decorative cover 40 becomes easy.
