In the present embodiment, as shown in fig. 5, the inclination angle θ4 of the light emission direction of the light source 83 with respect to the vertical direction is larger than the inclination angle θ3 of the emission surface 90 with respect to the horizontal direction, but the inclination angle θ4 may be the same as the inclination angle θ3 of the emission surface 90 with respect to the horizontal direction, or the inclination angle θ4 may be smaller than the inclination angle θ3. In the present embodiment, the light source 83 is disposed on the heat insulating space 5 side (upper side) than the bottom surface of the mounting recess 4c3 of the upper surface 4c of the inner case, but the light source 83 may be disposed on the lower side than the bottom surface of the mounting recess 4c 3.
(4) Effects of
In the present embodiment as described above, the emission surface 90 of the illumination cover 82 disposed opposite to the light source 83 is inclined so as to be more upward as it goes rearward at an angle θ3 larger than the angle θ2 of the inner box upper surface rear portion 4c2 with respect to the horizontal direction. Thus, when the user views the inside of the refrigerator compartment 6 from the front, the emitting surface 90 is less likely to be conspicuous, and the user is less likely to feel a glare, so that the aesthetic feeling of the inside of the refrigerator compartment is not impaired.
In the present embodiment, when the light emission direction of the light source 83 is inclined rearward than vertically downward, the light emitted from the light source 83 is less likely to radiate toward the front of the refrigerator compartment 6, and thus the user is less likely to feel a glare. In addition, when the concave-convex surface is provided on the upper surface (the illumination storage portion 81 side) of the emission surface 90, the light from the light source 83 can be irradiated at an angle close to perpendicular to the emission surface 90, and therefore, the light is easily scattered on the concave-convex surface, and the interior of the refrigerator compartment 6 can be uniformly illuminated.
In the present embodiment, when the front projection surface 91 provided on the front side of the emission surface 90 projects downward from the front portion 4c1 of the upper surface of the inner case, the front projection surface 91 is substantially visible as the illumination device 80 when the user views the inside of the refrigerator compartment 6 from the front, and the appearance of the inside of the refrigerator compartment 6 can be improved.
In particular, in the case where the shielding portion 88 covering the rear side of the front protruding surface 91 is provided between the front protruding surface 91 and the light source 83, it does not occur: the light from the light source 83 is transmitted through the front protruding surface 91 and through the inside of the illumination storage 81, and the aesthetic sense is impaired. At this time, in the case where the shielding portion 88 and the illumination housing portion 81 are provided integrally, the illumination cover 82 is attached to the illumination housing portion 81, and the shielding portion 88 is provided behind the front protruding surface 91, so that the assembling workability becomes excellent.
In addition, in the case where the coloring layer 91a is provided on the front projection surface 91, light from the light source 83 is less likely to pass through the front projection surface 91, and the front projection surface 91 can be decorated to improve the appearance of the interior of the refrigerator compartment 6.
In the present embodiment, when the illumination storage portion 81 is fitted into the heat insulating space 5 side of the mounting recess 4c3 provided in the upper surface 4c of the inner case and is provided on the upper surface 4c of the inner case, the illumination storage portion 81 is positioned by the mounting recess 4c3 at the time of assembling the refrigerator main body 2, and therefore, the illumination storage portion 81 can be easily arranged at a predetermined position, and misalignment of the illumination storage portion 81 due to the foamed heat insulating material filled in the heat insulating space 5 can be suppressed. In this case, the storage opening 84 of the illumination storage portion 81 communicates with the mounting opening 4c4 of the mounting recess 4c3, and the locking claw 93 is inserted from below through the mounting opening 4c4 and is locked with the locking portion 94 of the illumination storage portion 81. That is, since the locking claw 93 is inserted into the inner case 4 at the bottom surface of the mounting recess 4c3 recessed upward from the inner case upper surface 4c, the insertion portion of the locking claw 93 is difficult to see from the front, and the light from the light source 83 can be blocked by the mounting recess 4c3 even if the light leaks from the insertion portion of the locking claw 93, so that the appearance of the inside of the refrigerating chamber 6 can be improved.
