As shown in FIG. 5, in the first embodiment, the illumination device 18 (in other words, the LED 15) is arranged so that the optical axis faces the side wall portion on the side of the left and right side wall portions 2c that are close to each other. After the light emitted from the LED 15 is reflected by the left and right side wall portions 2c, the light proceeds to the front surface of the refrigerator compartment 2. For this reason, compared with the case where the illuminating device 18 is arrange | positioned toward the refrigerator compartment 2 front surface, the optical path until it goes out of the refrigerator compartment 2 from LED15 extends, and the irradiation range of light can be expanded. Further, since the convex portion is formed on the surface of the cover 14, diffuse reflection can be performed in a wider range.
In addition, since the light emitted from the LED 15 is reflected by the left and right side wall portions 2c, the left and right side wall portions 2c appear to emit light, so that a wide area in the refrigerator compartment 2 can be illuminated uniformly. .

  Therefore, even if food is placed in the refrigerator compartment 2, there is an effect that it does not become dark.

  Further, since the light emitted from the LED 15 is reflected by the left and right side wall portions 2c, the light amount is suppressed by the reflectance of the material used for the left and right side wall portions 2c, so that the amount of light reaching the user 24 can be suppressed. This has the effect that the user 24 does not feel dazzling.

  Moreover, since the wide range of the refrigerator compartment 2 looks bright, the visibility in the refrigerator compartment 2 of the user 24 can be improved, and the user 24 can be made to feel the cleanliness in the refrigerator compartment 2. Have.

  Further, the number of reflections at the left and right side wall portions 2c is not limited, and may be reflected a plurality of times. As the number of reflections increases, the optical path can be extended, so that the irradiation range can be widened. Further, since the number of reflections is large, it is possible to further reduce glare.

  In the first embodiment, the example in which the number of LEDs 15 used in the lighting device 18 on one side is four is given, but the number of LEDs 15 may be changed as shown in FIG. If the number of LEDs 15 is reduced, the material cost of the lighting device 18 can be reduced, and the cost of the entire lighting device 18 can be reduced.

  In the first embodiment, the example in which the optical axis 19 of the LED 15 is not tilted in the height direction as shown in FIGS. 1 to 3 has been given. However, as shown in FIG. It may be inclined in the direction. By tilting the optical axis 19 of the LED 15, the optical path can be further extended compared to when the LED 15 is not tilted, so that the irradiation range can be further widened.

As shown in FIG. 11, the illuminating device 18 according to the second embodiment is arranged such that the optical axis 19 faces the rear side wall portion 2 d excluding the cold air blowing duct 13. For this reason, after the light irradiated from LED15 is reflected by the back side wall part 2d, it reflects directly or right and left side wall part 2c, and advances to the front surface of the refrigerator compartment 2. Therefore, compared with the case where the illuminating device 18 is arranged toward the front surface of the refrigerator compartment 2, the optical path from the LED 15 to the outside of the refrigerator compartment 2 extends, and the light irradiation range can be expanded. Further, since the light emitted from the LED 15 is reflected by the rear side wall portion 2d, the rear side wall portion 2d (including the left and right side wall portions 2c when reflected by the left and right side wall portions 2c) is surface emitting. Therefore, the wide area in the refrigerator compartment 2 can be illuminated uniformly.

  Further, since the optical axis 19 of the LED 15 faces the rear side wall portion 2d, not only the rear side wall portion 2d and the left and right side wall portions 2c but also the edge of the rear side side wall portion 2d, which has been particularly dark conventionally, emits light. That is, the number of reflections can be increased as compared with the first embodiment, and the irradiation range can be expanded by further extending the optical path as compared with the first embodiment.

  Further, the rear side wall 2d and / or the left and right side walls 2c appear to emit light, and the cover 14 is formed with a convex portion so that it diffuses over a wide area in the refrigerator compartment 2. Since it can reflect, even if food is placed in the vicinity of the LED 15, light is not completely blocked, so it is difficult to darken.

  Further, the light emitted from the LED 15 is reflected by the back side wall portion 2d and / or the left and right side wall portions 2c, so that the light amount is suppressed by the reflectance of the material used for the side wall portion. This has the effect that the user 24 does not feel dazzling. In addition, since the number of reflections is larger than that in the first embodiment and the amount of light is suppressed by reflection at the side wall, the amount of light reaching the user 24 can be suppressed, and the user 24 does not feel more dazzling.

  Moreover, since the wide range of the refrigerator compartment 2 looks bright, the visibility in the refrigerator compartment 2 of the user 24 can be improved, and the user 24 can be made to feel the cleanliness in the refrigerator compartment 2. Have. Furthermore, since the wide range of the refrigerator compartment 2 is wider and brighter than that of the first embodiment, the visibility and the cleanliness of the user 24 are further enhanced.

For this reason, compared with the case where the illuminating device 18 is arrange | positioned toward the refrigerator compartment 2 front surface, the optical path until it goes out of the refrigerator compartment 2 from LED15 extends, and the irradiation range of light can be expanded. Further, since it is reflected by the cold air blowing duct 13, the cold air blowing duct 13 and the cover 14 itself appear to be shining and seem to emit surface light. A wide area inside can be illuminated uniformly.

  Further, for example, since light is reflected by the cover 14 having a rounded cool air blow duct 13 and a convex portion formed on the surface, the light can be diffusely reflected in a wider range.

  In addition, since the cold air duct 13 and the cover 14 themselves appear to shine, there is an effect that the back side of the refrigerator compartment 2 looks bright.

  In addition, even if food is placed near the LED 15 by uniformly illuminating a wide area in the refrigerator compartment 2 with the cold air blowing duct 13 and the cover 14 appearing to emit light, the light is completely blocked. Therefore, it is difficult to darken.

  In addition, since the light emitted from the LED 15 is reflected by the cold air duct 13 and the cover 14, the amount of light reaching the user 24 can be reduced because the amount of light is suppressed by the reflectance of the material used for these. The effect is that the person 24 does not feel dazzling.

  Moreover, since the wide range of the refrigerator compartment 2 looks bright, the visibility in the refrigerator compartment 2 of the user 24 can be improved, and the user 24 can be made to feel the cleanliness in the refrigerator compartment 2. Have.
