  That is, the opening 8 on the front surface of the refrigerator compartment 6 is opened and closed by two doors, a door 2 and a door 17. Although not shown in detail, the left end of the door 2 is pivotally supported by the refrigerator main body 1. The door 17 is pivotally supported at its right end to the cabinet main body 1 and is provided so as to be openable and closable in a swinging door type and a double door opening type in which each of the doors 17 is pivoted about its respective pivotal support portion. In addition, the left and right partition member 22 is attached to the left door 2 with a movable structure that does not hinder opening of the door 2.

  The doors 2 and 17 have throat portions 23 and 24 on the rear surfaces of the inner plates 14 and 19, which are the rear portions facing the refrigerator compartment 6, respectively. These throat portions 23, 24 are formed so as to protrude in a rectangular frame shape from the peripheral portions of the back surfaces of the inner plates 14, 19, as representatively shown by the throat portion 23 of the door 2 in FIG. And is hollow. As shown in FIGS. 1 to 3, pocket portions 25 and 26 are provided in a plurality of stages in each surrounding space of the throat portions 23 and 24. Lighting devices 27 and 28 are provided at upper and lower intermediate portions of one side portion of the throat portions 23 and 24 that extend in the vertical direction on the side of the shaft support portions.

  FIGS. 5 and 6 show the details of the lighting devices 27 and 28 as a representative of the lighting device 27 of the door 2, and a light source fixture 29 is incorporated in the throat portions 23 and 24. This light source fixture 29 is a container-like member that is entirely provided along the inner surfaces of the throat portions 23 and 24, and has a front-side (lower side in FIG. 6) opening and a tapered shape that becomes thinner toward the rear side (upper side). , The tip is closed.

  Accordingly, both the throat portions 23, 24 and the light source fixture 29 have a slope shape in which both side walls approach the tip, and the outer wall portions, which are the front side portions of the throat portions 23, 24, have a dimension D. (Especially, the thickness of each of the throat portions 23 and 24 is larger than the thickness of the throat portions 23 and 24). It is formed by punching in molding.

  In addition, an opening 31 slightly smaller than the opening 30 of the throat portions 23 and 24 is formed on the outer wall, which is the front side of the light source fixture 29, and is stretched outward from the peripheral edge of the opening 31. A protruding flange (tip flange) 32 is formed, and a holding claw 33 as a light source holding portion is provided inside the opening 31. The base of the light source fixture 29 is also formed with a flange (base flange) 34 that protrudes outward from the periphery thereof.

  With this configuration, the light source fixture 29 is inserted into the throat portions 23, 24, and the light source fixture 29 is attached to the inner surfaces 23a, 24a of the throat portions 23, 24 facing the opening 30 (only 23a is shown in FIG. 6). The rear surface 29a opposing the front side of the abutment is brought into contact with the light source, and the light sources are attached to the inner surfaces 23b and 24b (only 23b is shown in FIG. 6) of the throats 23 and 24 outside the periphery of the opening 30. The outer surface 32a of the front flange 32 of the tool 29 is abutted.

  A connector housing 35 is incorporated inside the outer plates 13 and 18 of the doors 2 and 17. In this connector housing 35, a lead wire insertion hole 36 is formed substantially at the center of the rear wall portion.

  Thereafter, the lead wires 39 of the circuit board 38 on which the LEDs 37 as the light sources of the lighting devices 27 and 28 are mounted are led out of the light source fixture 29 into the connector housing 35 through the lead wire insertion holes 36 of the connector housing 35, The output side connector 40 of the lead wire 39 at the distal end is connected to the input side connector 42 of the external lead 41 at the distal end. Thereafter, the connection portions are returned from the lead wire insertion hole 36 into the light source fixture 29, and a seal 43 integrated in advance in a portion of the external lead wire 41 near the connector 42 is pressed into the lead wire insertion hole 36 and the lead is inserted. The wire insertion hole 36 is sealed. The external lead wire 41 supplies power to the LED 37 from the housing main body 1 through the shaft support portion of the door 2.

  Then, the foamed heat insulating materials 16 and 21 are poured 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 join. At this time, a seal (for example, a soft tape) 44 is attached to the front surface of the base flange 34 of the light source mounting fixture 29 in advance, and the rear surface of the connector housing 35 (the lead wire insertion hole 36) is attached to the seal 44. Of the light source fixture 29 is sealed from the inside of the outer plates 13 and 18 (the space filled with the foamed heat insulating materials 16 and 21). As a result, the foamed heat insulating materials 16 and 21 injected into the outer plates 13 and 18 do not enter the inside of the light source fixture 29 and are located between the outer plate 13 and the inner plate 14 in the door 2 and in the door 17. The space between the outer plate 18 and the inner plate 19 is filled.

Further, after that, the circuit board 38 is attached by being engaged with the holding claws 33 from the opening 31 of the light source fixture 29, and thereafter, the opening of the light source fixture 29 is opened through the openings 30 of the throat parts 23 and 24. Shades 45 are attached to the part 31 by a plurality of mounting claws 45a, and the openings 30, 31 are closed. The shade 45 diffuses the light emitted from the LED 37 and is larger than the opening 31 of the light source fixture 29, but is a rectangle sized to fit in the opening 30 of the throat portions 23 and 24. 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 in a structure symmetrical to the lighting device 27 of the door 2.

FIG. 1 shows the doors 2 and 17 incorporating the lighting devices 27 and 28 in the fully opened state as described above. As is apparent from FIG. 1, the shades 45 from the LEDs 37 of the lighting devices 27 and 28 are used. The irradiation ranges L ₁ , L ₂ of the light illuminating the refrigerator compartment 6 through the refrigeration chamber 6 do not cover the doors 2, 17 (especially, the edges on their pivotal support sides). 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 tried not to make shadows by 2,17.

  In addition, FIGS. 1 to 3 show switches 46 and 47 which are door opening / closing detecting means provided in the heat insulating wall of the cabinet main body 1 corresponding to the lighting devices 27 and 28, and these are, for example, tact switches. Although not shown in detail, a protrusion protruding into the storage body 1 is pressed by the throat portions 23 and 24 (one side of each shaft support portion) by closing the doors 2 and 17. Thus, the closing of the doors 2 and 17 is detected, and the opening of the doors 2 and 17 is detected by releasing the pressing of the protrusion by opening the doors 2 and 17. 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 emit the LED 37 when the switches 46 and 47 detect the opening of the doors 2 and 17, and turn off the LED 37 when detecting the closing of the doors 2 and 17.

  FIGS. 5 and 6 show grooves 48 formed in the inner plates 14 and 19 near the outer sides of the throat portions 23 and 24 of the doors 2 and 17, and the grooves 48 close the doors 2 and 17. Sometimes, a gasket (not shown) for sealing the opening 8 of the cabinet main body 1 is attached by insertion, and has projections 48b on both sides of the gasket insertion opening 48a to prevent the gasket from being removed. ing.

Next, the operation of the refrigerator having the above configuration will be described.
In the refrigerator having the above structure, when opening the door 2, 17, by the switch 46, 47 for detecting the opening of the door 2, 17 causes the light LED37 of the lighting device 27, illumination range _{L 1} in FIG. 1 , as indicated by L _2, illuminates the refrigerating compartment 6.

  In this case, when only one of the doors 2 and 17 is opened, one of the switches 46 and 47 on the side of the opened door detects the opening of the door, so that one of the lighting devices 27 and 28 is opened. The LED 37 of the illuminating device on the door side is lit 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. As a result, power consumption is reduced.

  In the refrigerator having the above-described configuration, the lighting devices 27 and 28 are provided on the throat portions 23 and 24 of the doors 2 and 17, respectively. Since the storage items are not placed near the lighting devices 27 and 28 when the door 17 is opened, the illumination is not obstructed by the storage items, and therefore, the illuminance of the refrigerator 6 does not greatly decrease. In addition, the irradiation light does not directly enter the eyes of the user who opens the doors 2 and 17 and looks into the refrigerating room 6, so that the user is less likely to feel dazzling.

In addition, in the refrigerator having the above-described configuration, even when the lighting devices 27 and 28 are provided in the throat portions 23 and 24 of the doors 2 and 17, the light emitted from the lighting devices 27 and 28 casts the shadows of the doors 2 and 17. In this case, no shadow is produced by the doors 2 and 17 in each of the irradiation ranges L ₁ and L _2, and there is no lack of the illumination range 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 the LED 37 as a light source and the light source fixture 29 for mounting the LED 37, and the light source 29 diffuses the irradiation light of the LED 37. An opening 31 for mounting a shade 45 to be mounted and a front flange 32 projecting outward from the peripheral edge of the opening 31 are provided on the front side, and the inner space of the throat portions 23 and 24 of the doors 2 and 17 is closed by a door. A base flange 34 is provided at the base for sealing from the foamed and heat-insulating material filling space 2, 17, and an opening 30 for accommodating the shade 45 is formed in the throats 23, 24 of the doors 2, 17. The back surface 29a facing the front side of the light source fixture 29 is brought into contact with the inner surfaces 23a, 24a of the throats 23, 24 facing the opening 30, and the openings of the throats 23, 24 are brought into contact. The inner surface 23b of the outer portion of the periphery of the 0 to 24b, is made to contact the outer surface 32a of the front portion flange 32 of the light source fixture 29.

  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 are in contact with the filling pressure of the foam insulation materials 16 and 21 of the doors 2 and 17, respectively. (The inner surfaces 23a and 24a facing the openings 30 of the throat portions 23 and 24, and the inner surfaces 23b and 24b of the portions outside the peripheral edge of the opening 30 of the throat portions 23 and 24). Is fixed in the throat portions 23, 24, that is, the seal 44 is fixed by the rear surface of the case portion 37 of the connector housing 35 in a state where the light source fixture 29 does not escape due to the filling pressure of the foam heat insulating materials 16, 21. Since it is pressed against the front surface of the base flange 34 of the 29, the inside of the light source fixture 29, that is, the portion where the LED 37 is located, is more reliably sealed when the foam insulation materials 16 and 21 are filled. Can so as not to impair the lighting effect LED37 with foam insulation 16 and 21.

  Further, in the refrigerator having the above-described 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. Thereby, the opening 30 can be easily formed. In particular, near the outside of the throat portions 23 and 24 of the doors 2 and 17, a gasket mounting groove 48 is formed in the inner plates 14 and 19, and the groove 48 is a projection for preventing the gasket from being removed. Although 48b is provided on both sides of the gasket insertion opening 48a, it is formed by forcibly releasing the mold back and forth (up and down in FIG. 6).

  On the other hand, the opening portions 30 of the throat portions 23 and 24 are provided in a left-right direction that intersects (particularly orthogonally) with the opening portion 48a of the groove 48, and the opening portion 30 is die-cut according to the direction. If it is attempted to form it by (mold release), it interferes with the release structure of the inner plates 14, 19 in which the groove 48 for mounting the gasket is formed, and cannot be formed, or the mold structure is extremely complicated and expensive. It will be.

However, in the refrigerator having the above-described structure, 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. The opening 30 can be easily and inexpensively formed by a simple mold in which the opening 30 is separated only in the front and rear directions.
In this case, instead of the step D, the throat portions 23 and 24 of the doors 2 and 17 may be provided with a gradient having a similar gradient.

  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 substantially flush with the surface portion. As a result, the shade 45 hardly protrudes outside the throat portions 23, 24 of the doors 2, 17, and the shade 45 is minimized to prevent cold air from leaking and to secure the width of the pockets 25, 26. The shade 45 can be accommodated in the gap between the throat portions 23, 24 of the cabinet main body 1 and the inner surface of the cabinet main body 1, and the throat portions 23, 24 of the doors 2, 17 and the inner surface of the cabinet main body 1 can be accommodated. It is possible to eliminate the need to increase the gap size between the pocket portions 25 and 26, and to prevent the leakage of the cool air and to secure the width of the pocket portions 25 and 26.

  On the other hand, FIGS. 7 and 8 show the second and third embodiments, and the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Only the part will be described.

[Second embodiment]
In the second embodiment shown in FIG. 7, a circuit board in which an LED 37 is mounted on the holding claw 51 using a light source fixing tool 52 having a holding claw 51 at an open distal end portion instead of the light source fixing tool 29 described above. 38 are engaged and mounted. In this case, the front ends of the doors 2, 17 and the throat portions 23, 24 are also open from the outer side surface to the inner side surface, and a shade 53 in place of the above-described shade 45 is attached to the opening. Thus, the open end portions of the throat portions 23 and 24 are closed. Thus, in this case, the shade 53 is provided at the tip of the throat portions 23 and 24 of the doors 2 and 17.

  By doing so, the irradiation range of the light radiated from the LEDs 37 of the lighting devices 27 and 28 to the refrigerator compartment 6 through the shade 53 can be further increased. There is an effect that it is possible to easily irradiate the refrigerator compartment 6 even when is opened at a small angle.

[Third Embodiment]
In the third embodiment shown in FIG. 8, the LED (light source) 37 has a wide-angle specification for irradiating light at a wide angle. Specifically, the irradiation ranges L ₃ and L ₄ of the light irradiated from the LED 37 to the refrigerator compartment 6 through the shade 45 are replaced with the above-described irradiation ranges L ₁ and L _2, and are larger than, for example, 90. The angle is in degrees.

  By doing so, it is easy for the user to understand that the light irradiation range changes with a change in the opening angle of the doors 2 and 17 when the light irradiation range is small. The change of the light irradiation range becomes difficult for the user to understand, and the usability can be improved.
