The output-side connector 40 of the lead wire 39 at the tip is connected to the input-side connector 42 of the external lead wire 41 at the tip. After that, those connection portions are returned from the lead wire insertion hole 36 into the light source fitting 29, and the seal 43 pre-integrated in the portion of the external lead wire 41 near the connector 42 is press-fitted into the lead wire insertion hole 36 to lead. The wire insertion hole 36 is sealed. The external lead wire 41 supplies power to the LED 37 from the main body 1 through the shaft support portion of the door 2.

After that, the foamed heat insulating materials 16 and 21 are injected into the outer plates 13 and 18 of the doors 2 and 17, and the inner plates 14 and 19 are assembled to the outer plates 13 and 18 by the peripheral frames 15 and 20, respectively. Combine and combine. At this time, a seal (for example, soft tape) 44 is attached to the front surface of the base flange 34 of the light source attachment 29 in advance, and the rear surface (lead wire insertion hole 36) of the connector housing 35 is attached to the seal 44. The inside of the light source connector 29 is sealed from the inside of the outer plates 13 and 18 (filling space of the foamed heat insulating materials 16 and 21) by pressure-welding the surrounding portion of the light source. As a result, the foamed heat insulating materials 16 and 21 injected into the outer plates 13 and 18 do not invade the inside of the light source fixture 29, and are between the outer plate 13 and the inner plate 14 in the door 2 and in the door 17. It is filled between the outer plate 18 and the inner plate 19, respectively.

The shade 45 is attached to the portion 31 by a plurality of attachment claws 45a to close the openings 30 and 31. The shade 45 diffuses the light emitted by the LED 37, and although it is larger than the opening 31 of the light source fixture 29, it is a rectangle having a size that fits in the openings 30 of the throat portions 23 and 24, and the surface portion is in the mounted state. It is located almost flush with the surface of the throat portions 23 and 24.
The lighting device 28 of the door 17 is provided with a structure symmetrical to that of the lighting device 27 of the door 2.

FIG. 1 shows the doors 2 and 17 in which the lighting devices 27 and 28 are incorporated as described above in a fully open state, and as is clear from FIG. 1, the LED 37 to the shade 45 of the lighting devices 27 and 28 are shown. _{The irradiation ranges L 1} and L ₂ of the light radiated to the refrigerating chamber 6 through the doors 2 and 17 (particularly, the edge portions on the shaft support side thereof) are not exposed to the doors 2 and 17, respectively, that is, the light. irradiation range L ₁ door 2 during the door 17 in the irradiation range L ₁ of the light, have as not to position respectively, whereby the door irradiating light of the lighting device 27, 28 I try not to cast shadows by 2 and 17.

In addition, FIGS. 1 to 3 show switches 46 and 47 which are door open / close detection means provided in the heat insulating wall of the refrigerator body 1 corresponding to the lighting devices 27 and 28, and these are, for example, tact switches. And microswitches, which are not shown in detail, but both of which have protrusions protruding inside the main body 1 are pressed by the throat portions 23 and 24 (one side of each shaft support portion) due to the closing of the doors 2 and 17. As a result, the closing of the doors 2 and 17 is detected, and the pressing of the protrusion is released by the opening of the doors 2 and 17, so that the opening of the doors 2 and 17 is detected. As shown in FIG. 2, the switches 46 and 47 are installed at positions where they do not come into direct contact with the lighting devices 27 and 28. The lighting devices 27 and 28 cause the LED 37 to emit light when the switches 46 and 47 detect the opening of the doors 2 and 17, and extinguish the LED 37 when the switches 46 and 47 detect the closing of the doors 2 and 17.

Further, FIGS. 5 and 6 show grooves 48 formed in the inner plates 14 and 19 in the vicinity of the outer side of the throat portions 23 and 24 of the doors 2 and 17, and the grooves 48 close the doors 2 and 17. It is for attaching a gasket (not shown) that seals the opening 8 of the refrigerator body 1 by insertion, and has protrusions 48b for retaining the gasket on both sides of the opening 48a for inserting the gasket. ing.

Next, the operation of the refrigerator having the above configuration will be described.
In the refrigerator having the above configuration, when the doors 2 and 17 are opened, the switches 46 and 47 detect the opening of the doors 2 and 17 to cause the LED 37 of the lighting devices 27 and 28 to emit light, and the irradiation range L _{1 is shown in FIG.} , L ₂ illuminates the refrigerator compartment 6.

Further, in this case, when only one of the doors 2 and 17 is opened, the opened door-side switch of the switches 46 and 47 detects the opening of the door, so that the lighting devices 27 and 28 are opened. The LED 37 of the lighting device on the door side is made to emit light to illuminate the refrigerator compartment 6. That is, in this case, only the LED 37 of the lighting device on the open door side of the doors 2 and 17 is made to emit light, and the LED 37 of the lighting device on the door side that is not opened is not made to emit light. This saves power consumption.

In the refrigerator having the above configuration, the lighting devices 27 and 28 are provided in the throat portions 23 and 24 of the doors 2 and 17, and the doors 2 and 2 are similar to those in which the interior light is provided on the wall surface of the refrigerator compartment 6. Since no stored items are placed in the vicinity of the lighting devices 27 and 28 when the 17 is opened, the lighting is not obstructed by the stored items, and therefore the decrease in illuminance with respect to the refrigerating room 6 is not large. Moreover, since the irradiation light does not directly enter the eyes of the user who opens the doors 2 and 17 and looks into the refrigerator compartment 6, the user is less likely to feel dazzling.

At the same time, in the refrigerator having the above configuration, even if the lighting devices 27 and 28 are provided on the throat portions 23 and 24 of the doors 2 and 17, the light emitted by the lighting devices 27 and 28 casts a shadow by the doors 2 and 17. and to avoid creating, thereby, can not shadow by the door 2, 17 thereof to the respective illumination range L _1, L _2, without the illumination range of the refrigerator is lack partially, sufficient in the refrigerator A lighting effect can be obtained.

Further, in the refrigerator having the above configuration, the lighting devices 27 and 28 are configured to include an LED 37 as a light source and a light source attachment 29 for attaching the LED 37, and the irradiation light of the LED 37 is diffused to the light source attachment 29. An opening 31 for mounting the shade 45 and a flange 32 at the tip protruding outward from the peripheral edge of the opening 31 are provided on the front side portion, and the internal space of the throat portions 23 and 24 of the doors 2 and 17 is opened. A base flange 34 for sealing from the foamed heat insulating material filling space of 2 and 17 is provided at the base, and an opening 30 for accommodating the shade 45 is formed in the throat portions 23 and 24 of the doors 2 and 17. The inner surfaces 23a and 24a of the throat portions 23 and 24 facing the openings 30 are brought into contact with the back surface portion 29a facing the front side portion of the light source attachment 29, and the peripheral edges of the openings 30 of the throat portions 23 and 24 are brought into contact with each other. The outer surface 32a of the tip flange 32 of the light source fixture 29 is brought into contact with the inner surfaces 23b and 24b of the outer portion.

As a result, the back surface 29a of the light source fixture 29 and the outer surface 32a of the front flange 32 of the light source fixture 29 come into contact with each other with respect to the filling pressure of the foamed heat insulating materials 16 and 21 of the doors 2 and 17, respectively. (Inner surfaces 23a, 24a facing the openings 30 of the throat portions 23, 24, inner surfaces 23b, 24b of the portion outside the peripheral edge of the openings 30 of the throat portions 23, 24), and the light source fixture 29 Is fixed in the throat portions 23 and 24, that is, the seal 44 is attached to the light source attachment by the rear surface of the case portion 37 of the connector housing 35 in a state where the light source attachment 29 does not escape due to the filling pressure of the foamed heat insulating materials 16 and 21. Since it is pressed against the front surface of the base flange 34 of 29, the inside of the light source fixture 29 when the foamed heat insulating materials 16 and 21 are filled, that is, the part where the LED 37 is located can be more reliably sealed, and the lighting effect of the LED 37 is foamed. The heat insulating materials 16 and 21 can be used so as not to damage the material.

Further, in the refrigerator having the above configuration, the throat portions 23 and 24 of the doors 2 and 17 are provided with a step D for forming the opening 30 for accommodating the shade 45 by die cutting. As a result, the opening 30 can be easily formed. In particular, in the vicinity of the outer side of the throat portions 23 and 24 of the doors 2 and 17, a groove 48 for attaching a gasket is formed in the inner plates 14 and 19, and this groove 48 is a protrusion for retaining the gasket. Although 48b is provided on both sides of the gasket insertion opening 48a, it is formed by forcibly releasing the mold in the front-rear direction (upper and lower in FIG. 6).

On the other hand, the openings 30 of the throat portions 23 and 24 are provided in the left-right direction intersecting (particularly orthogonal to) the openings 48a of the grooves 48, and the openings 30 are die-cut according to the orientation. If it is attempted to be formed by (remove), it interferes with the release structure of the groove 48 for mounting the gaskets of the inner plates 14 and 19, and cannot be formed, or those mold structures are extremely complicated and expensive. It becomes a thing.

However, in the refrigerator having the above configuration, the throat portions 23 and 24 of the doors 2 and 17 are provided with a step D for forming the opening 30 by die cutting, whereby the opening 30 is formed on the inner plates 14 and 19. Since it can be formed by the same front and rear mold release as the gasket mounting groove 48, the opening 30 can be easily and inexpensively formed with a simple mold that can be released only in the front and rear.
In this case, the throat portions 23 and 24 of the doors 2 and 17 may be provided with an inclination having a slope similar to that of the step D instead of the step D.

In addition, in the refrigerator having the above configuration, the shade 45 is provided on the throat portions 23 and 24 of the doors 2 and 17 so as to be almost flush with the surface portion. As a result, the shade 45 hardly protrudes outward from the throat portions 23 and 24 of the doors 2 and 17, and is suppressed to the minimum necessary to prevent leakage of cold air and secure the width dimension of the pocket portions 25 and 26. The shade 45 can be accommodated within the gap between the throat portions 23, 24 of the doors 2, 17 and the inner side surface portion of the storage body 1, and the throat portions 23, 24 of the doors 2, 17 and the inner side surface portion of the storage body 1 can be accommodated. It is possible to eliminate the need to increase the size of the gap between the door and the door, so as not to hinder the prevention of leakage of cold air and the securing of the width dimension of the pocket portions 25 and 26.

With respect to the above, FIGS. 7 and 8 show the second and third embodiments, and the same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Only the part will be described.
