Further, in this case, when only one of the doors 2 and 17 is opened, the switch on the side of the opened door among the switches 46 and 47 detects the opening of the door, thereby opening the lighting devices 27 and 28. Then, the LED 37 of the lighting device on the side of the door is made to emit light to illuminate the refrigerator compartment 6. - 特許庁That is, in this case, only the LED 37 of the lighting device on the opened door side of the doors 2 and 17 is made to emit light, and the LED 37 of the lighting device on the opened door side is not made to emit light. This is intended to reduce power consumption.

In the refrigerator constructed as described above, the illumination devices 27 and 28 are provided at the throat portions 23 and 24 of the doors 2 and 17, and the doors 2 and 2 are provided with internal lights on the wall surfaces of the refrigerator compartment 6. Since no stored goods are placed in the vicinity of the lighting devices 27 and 28 when the door 17 is opened, the lighting is not blocked by the stored goods, so that the illuminance for the refrigerator compartment 6 does not decrease significantly. In addition, the user who opens the doors 2 and 17 and looks into the refrigerator compartment 6 does not see the light directly, so that the user does not feel dazzling.

In addition, in the above-configured refrigerator, even if the lighting devices 27 and 28 are provided at the throat portions 23 and 24 of the doors 2 and 17, the light emitted from the lighting devices 27 and 28 casts shadows from the doors 2 and 17.

You can get lighting effects.

In the refrigerator having the above configuration, the illumination devices 27 and 28 are configured to have the LED 37 as a light source and the light source fixture 29 for mounting the LED 37. The light source fixture 29 diffuses the light emitted from the LED 37. An opening 31 to which a shade 45 is mounted, and a tip flange 32 projecting outward from the peripheral edge of the opening 31 are provided on the front side, and the internal spaces of the throats 23 and 24 of the doors 2 and 17 are provided as door openings. A base flange 34 is provided at the base for sealing from the foam insulation filling space of the doors 2, 17, and the throats 23, 24 of the doors 2, 17 are formed with an opening 30 for accommodating the shade 45, The inner surfaces 23a and 24a of the throat portions 23 and 24 facing the opening 30 are brought into contact with the rear surface portion 29a facing the front side portion of the light source fixture 29, and the peripheral edge portion of the opening portion 30 of the throat portions 23 and 24 is pressed. The outer surface 32a of the tip flange 32 of the light source fixture 29 is brought into contact with the inner surfaces 23b, 24b of the outer portions.

As a result, the rear portion 29a of the light source fixture 29 and the outer surface 32a of the front flange 32 of the light source fixture 29 are brought into contact with each other against the filling pressure of the foamed heat insulating materials 16 and 21 of the doors 2 and 17. (Inner surfaces 23a and 24a of the throat portions 23 and 24 facing the opening 30, and inner surfaces 23b and 24b of the throat portions 23 and 24 outside the peripheral portion of the opening 30). is fixed in the throat portions 23 and 24, that is, in a state where the light source fixture 29 does not escape due to the filling pressure of the foamed heat insulating materials 16 and 21, the seal 44 is secured to the light source fixture by the rear surface of the case portion 37 of the connector housing 35. 29 is pressed against the front surface of the base flange 34, the inside of the light source fixture 29, i.e., the portion where the LED 37 is positioned, can be more reliably sealed when the foam insulation materials 16, 21 are filled, and the lighting effect of the LED 37 is enhanced. The heat insulating materials 16 and 21 can prevent damage.

Further, in the refrigerator constructed as described above, the throat portions 23 and 24 of the doors 2 and 17 are provided with a step D for forming the opening portion 30 for accommodating the shade 45 by die-cutting. This facilitates formation of the opening 30 . In particular, grooves 48 for attaching gaskets are formed in the inner plates 14, 19 in the vicinity of the outer sides of the throat portions 23, 24 of the doors 2, 17, and the grooves 48 are projections for preventing the gaskets from coming off. 48b are provided on both sides of the opening 48a for inserting the gasket, but are formed by forcibly releasing the mold in the front and rear directions (up and down in FIG. 6).

On the other hand, the openings 30 of the throats 23 and 24 are provided in the left-right direction crossing (especially perpendicular to) the opening 48a of the groove 48, and the openings 30 are punched in the same direction. If it is attempted to form by (mold release), it interferes with the release structure for forming the groove 48 for mounting the gasket of the inner plates 14, 19, so that it cannot be formed, or the mold structure is extremely complicated and expensive. become a thing.

However, in the refrigerator configured as described above, a step D is provided in the throat portions 23 and 24 of the doors 2 and 17 for forming the opening portion 30 by die-cutting. Since the opening 30 can be formed by the same front and rear mold release as the gasket mounting groove 48, the opening 30 can be formed easily and inexpensively with a simple mold that is only front and rear released.
In this case, instead of the step D, the throat portions 23 and 24 of the doors 2 and 17 may be provided with an inclination having a similar gradient.

In addition, in the refrigerator constructed as described above, the shades 45 are provided on the throat portions 23 and 24 of the doors 2 and 17 so as to be substantially flush with the surface portions. As a result, the shade 45 hardly protrudes outward from the throat parts 23, 24 of the doors 2, 17, and the door 2 is kept to the minimum required for preventing leakage of cold air and securing the width dimension of the pocket parts 25, 26. , 17 and the inner side surface of the main body 1, the shade 45 can be accommodated within the gap dimension between the throats 23, 24 of the doors 2, 17 and the inner side surface of the main body 1. It is possible to eliminate the necessity of enlarging the gap between and prevent leakage of cold air and secure the lateral width of the pocket portions 25 and 26 without hindrance.
