Next, the structure of the illumination device 80 will be described mainly with reference to fig. 4 to 6.

The illumination device 80 includes: an illumination housing section 81 provided on the side (upper side) of the heat insulating space 5 of the mounting recess 4c3 on the inner box upper surface 4 c; a lighting cover 82 provided below the mounting recess 4c 3; and a light source 83 such as an LED.

The illumination storage portion 81 is formed of a vertically flat disk-shaped member provided with a storage opening portion 84 at a lower side, and a flange portion 85 protrudes outward from a peripheral edge of the storage opening portion 84. The mounting recess 4c3 provided in the inner box upper surface 4c is inserted into the storage opening 84 from below, and the illumination storage section 81 is mounted on the inner box upper surface 4c so as to be fitted into the heat insulation space 5 side of the mounting recess 4c 3.

When the illumination storage section 81 is attached to the inner box upper surface 4c in this way, as shown in fig. 5, the flange portion 85 contacts the heat insulation space 5 side of the peripheral edge portion of the attachment concave portion 4c3, the storage opening portion 84 vertically communicates with the attachment opening portion 4c4 of the attachment concave portion 4c3, and the lower portion of the illumination storage section 81 is opened.

The shielding portion 88 is provided along the width direction of the refrigerator 1 substantially over the entire illumination storage portion 81, and can shield at least a part of forward light of light emitted from the light source 83.

The lighting cover 82 is a molded body of acrylic resin or the like having high transparency, and the lighting cover 82 is attached to the attachment concave portion 4c3 of the inner box upper surface 4c, and is used for closing the storage opening portion 84 of the lighting storage portion 81, diffusing light from the light source 83, and irradiating the light into the refrigerating compartment 6.

The lighting cover 82 includes: a peripheral wall protruding upward from a peripheral edge portion of the emission surface 90 facing the light source 83 in the vertical direction is formed in a vertically flat plate shape and opens upward.

Specifically, the lower side (the refrigerating compartment 6 side) of the emission surface 90 is inclined so as to be directed upward as it goes rearward, and thus is formed as an inclined surface having an angle θ 3 with respect to the horizontal direction larger than the angles θ 1 and θ 2 with respect to the horizontal direction of the inner box upper surface front portion 4c1 and the inner box upper surface rear portion 4c 2. The upper surface (illumination housing 81 side) of the emission surface 90 is formed as a concave-convex surface in which a plurality of ridges extending in the width direction are arranged in the front-rear direction, thereby diffusing the light emitted from the light source 83.

The upper ends of the front projection surface 91 and the rear projection surface 92 projecting from the front end and the rear end of the projection surface 90 are provided with: and a locking claw 93 projecting upward. The locking claw 93 is inserted from below into the mounting opening 4c4 of the mounting recess 4c3 provided in the inner box upper surface 4c, and is locked to the locking portion 94 provided in the illumination storage portion 81. Accordingly, the lighting cover 82 is fixed to the inner box upper surface 4c so as to close the mounting opening 4c4 of the mounting recess 4c 3.

In a state where the lighting cover 82 is attached to the attachment recess 4c3 of the inner box upper surface 4c, the front projection surface 91 projects downward from the inner box upper surface front portion 4c 1. The front protruding surface 91 may be provided with a colored layer 91a, and the colored layer 91a may be colored by: the front projection surface 91 may be inclined to be directed forward as it goes upward, for example, a metallic color such as silver or the same color as the inner box 4. The colored layer 91a may be formed on the front projection surface 91 by any method, for example: by attaching separate sheets, by heat bonding or coating, by plating or vapor deposition, or the like.

In a state where the lighting cover 82 is fixed to the attachment recess 4c3 of the inner box upper surface 4c, the shielding portion 88 is disposed between the lighting board 86 held by the holding portion 87 and the front protruding surface 91, and the shielding portion 88 covers the rear side of the front protruding surface 91 substantially in the entire width direction.

In a state where the lighting cover 82 is attached to the attachment recess 4c3 of the inner box upper surface 4c, the rear protruding surface 92 protrudes downward from the inner box upper surface rear portion 4c 2. In addition, it is preferable that the amount of projection from the inner box upper surface rear portion 4c2 (the rear end of the mounting recess 4c 3) to the lower end of the rear projection surface 92 is smaller than: the amount of projection from the inner box upper surface front portion 4c1 (the front end of the mounting recess 4c 3) to the lower end of the front projection surface 91.

The light source 83 is housed in a space defined by the illumination housing portion 81 and the illumination cover 82, and the light source 83 irradiates light at an angle close to perpendicular to the emission surface 90, and the light source 83 is disposed so as to be inclined such that the emission direction of the light is inclined rearward with respect to the vertical direction, for example, such that the angle formed by the emission direction of the light from the light source 83 and the normal direction of the emission surface 90 is 10 ° or less.

As shown in fig. 5, in the present embodiment, although the inclination angle θ 4 of the light emission direction of the light source 83 with respect to the vertically downward direction is larger than the inclination angle θ 3 of the emission surface 90 with respect to the horizontal direction, the inclination angle θ 4 may be the same as the inclination angle θ 3 of the emission surface 90 with respect to the horizontal direction, and the inclination angle θ 4 may be smaller than the inclination angle θ 3. In the present embodiment, the light source 83 is disposed on the side of the heat insulation space 5 (upper side) with respect to the bottom surface of the mounting recess 4c3 of the inner box upper surface 4c, but the light source 83 may be disposed on the lower side with respect to the bottom surface of the mounting recess 4c 3.

(4) Effect

In the present embodiment described above, the emission surface 90 of the illumination cover 82 disposed to face the light source 83 is inclined at an angle θ 3 larger than the angle θ 2 of the inner box upper surface rear portion 4c2 with respect to the horizontal direction and is inclined upward as going rearward. Thus, when the user views the interior of refrigerating room 6 from the front, emission surface 90 is less conspicuous, and it is less likely to give a dazzling feeling to the user, so that the beauty of the interior of the refrigerating room is not impaired.

In the present embodiment, when the light emission direction of light source 83 is inclined rearward from the vertical lower direction, the light emitted from light source 83 is less likely to be emitted toward the front of refrigerating room 6, and it is more unlikely that the user will feel dazzling. In addition, when the upper surface (illumination housing 81 side) of emission surface 90 is provided with the uneven surface, light from light source 83 can be irradiated at an angle close to perpendicular to emission surface 90, and therefore, light is easily scattered by the uneven surface, and the inside of refrigerating room 6 can be uniformly illuminated.

In the present embodiment, when the front protruding surface 91 provided on the front side of the emitting surface 90 protrudes downward from the inner box upper surface front portion 4c1, when the user views the inside of the refrigerating compartment 6 from the front, substantially only the front protruding surface 91 is visible as the lighting device 80, and the appearance of the inside of the refrigerating compartment 6 can be improved.

In particular, when the shielding portion 88 for covering the rear side of the front projection surface 91 is provided between the front projection surface 91 and the light source 83, the following will not occur: the light from the light source 83 passes through the front protruding surface 91 and passes through the inside of the illumination housing portion 81, and the aesthetic appearance is impaired. At this time, when the shielding portion 88 is provided integrally with the illumination housing portion 81, the illumination cover 82 is attached to the illumination housing portion 81 and the shielding portion 88 is provided on the rear side of the front protruding surface 91, so that the assembling workability becomes excellent.

In addition, when the colored layer 91a is provided on the front projection surface 91, light from the light source 83 is less likely to transmit 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 section 81 is fitted to the heat insulation space 5 side of the mounting recess 4c3 provided in the inner box upper surface 4c and provided in the inner box upper surface 4c, the illumination storage section 81 is positioned by the mounting recess 4c3 at the time of assembling the refrigerator main body 2, the illumination storage section 81 can be easily arranged at a predetermined position, and the displacement of the illumination storage section 81 due to the foamed heat insulating material filled in the heat insulation space 5 can be suppressed. In this case, the housing opening 84 of the illumination housing 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 locked to the locking portion 94 of the illumination housing 81. That is, since the locking claw 93 is inserted into the inner box 4 at the bottom surface of the attachment concave portion 4c3 that is recessed upward from the inner box upper surface 4c, the insertion portion of the locking claw 93 is not easily visible from the front, and light from the light source 83 can be blocked by the attachment concave portion 4c3 even if the light leaks from the insertion portion of the locking claw 93, so that the appearance inside the refrigerating compartment 6 can be improved.
