The space between the outer plate 18 and the inner plate 19 is filled.

After that, the circuit board 38 is mounted by being engaged with the holding claw 33 from the opening 31 of the light source fixture 29, and thereafter the opening of the light source fixture 29 is opened from the opening 30 of the throat portions 23, 24. The shade 45 is attached to the portion 31 by a plurality of mounting claws 45a to close the openings 30 and 31. The shade 45 diffuses the light emitted from the LED 37 and is a rectangle that is larger than the opening 31 of the light source fixture 29 but fits in the opening 30 of the throat portions 23 and 24. It is located substantially flush with the surface portions of the throat portions 23 and 24.
Note that the lighting device 28 of the door 17 is provided in a symmetrical structure with the lighting device 27 of the door 2.

FIG. 1 shows the doors 2 and 17 incorporating the lighting devices 27 and 28 as described above in the fully opened state. As is apparent 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 irradiated to the refrigerating chamber 6 through the doors are not applied to the doors 2 and 17 (especially, the end portions on the shaft support side thereof), that is, 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 The shadows 2 and 17 are not made.

  In addition, FIGS. 1 to 3 show switches 46 and 47 which are door opening / closing detection means provided in the heat insulating wall of the cabinet body 1 corresponding to the lighting devices 27 and 28. These are, for example, tact switches. Although not shown in detail, the protrusions projecting inside the cabinet body 1 are pressed by the throat portions 23 and 24 (one side portion of each shaft support portion side) when the doors 2 and 17 are closed. Accordingly, 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 protrusions by the opening of the doors 2 and 17. As shown in FIG. 2, the switches 46 and 47 are installed at positions where they do not directly contact the lighting devices 27 and 28. The illuminating devices 27 and 28 are configured to cause the LED 37 to emit light when the switches 46 and 47 detect the opening of the doors 2 and 17 and to extinguish the LED 37 when the closing of the doors 2 and 17 is detected.

  Further, FIGS. 5 and 6 show a groove 48 formed in the inner plates 14 and 19 in the vicinity of the outside of the throat portions 23 and 24 of the doors 2 and 17, and this groove 48 closes the doors 2 and 17. It is sometimes used to attach a gasket (not shown) for sealing the opening 8 of the main 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.

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

  And in the refrigerator of the said structure, the illuminating devices 27 and 28 are provided in the throat parts 23 and 24 of the doors 2 and 17, and the door 2 like what provided the interior lamp in the room wall surface of the refrigerator compartment 6 is provided. Since the stored items are not placed near the lighting devices 27 and 28 when the door 17 is opened, the lighting is not blocked by the stored items, and therefore the decrease in illuminance with respect to the refrigerator compartment 6 is not increased. In addition, 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.

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 is shaded by the doors 2 and 17. Therefore, shadows by the doors 2 and 17 are not formed on the respective irradiation ranges L ₁ and L _2, and a part of the illumination range in the storage is not lost. Lighting effect can be obtained.

  Moreover, in the refrigerator of the said structure, the illuminating devices 27 and 28 are set as the structure which has LED37 which is a light source, and the light source fixture 29 which attaches this LED37, and the irradiation light of LED37 is diffused in the light source fixture 29 An opening 31 for mounting the 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 interior spaces of the throat portions 23 and 24 of the doors 2 and 17 are provided as doors. The base flange 34 for sealing from the space filled with the foam insulation material 2 and 17 is provided at the base, and the opening portion 30 for accommodating the shade 45 is formed in the throat portions 23 and 24 of the doors 2 and 17. A back surface portion 29a facing the front side portion of the light source fixture 29 is brought into contact with the inner surfaces 23a, 24a of the throat portions 23, 24 facing the opening portion 30, and the opening portions of the throat portions 23, 24 are brought into contact with each other. 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 portion 29a of the light source fixture 29 and the outer surface 32a of the front flange 32 of the light source fixture 29 abut against each other against the filling pressure of the foam heat insulating materials 16 and 21 of the doors 2 and 17. (The inner surfaces 23a, 24a facing the opening 30 of the throat portions 23, 24, the inner surfaces 23b, 24b of the outer portions of the throat portions 23, 24). Is fixed in the throat portions 23, 24, that is, the seal 44 is secured to the light source fixture 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. 29 is pressed against the front surface of the base flange 34, so that the interior of the light source fixture 29, that is, the portion where the LED 37 is located can be 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 housing the shade 45 by die cutting. Thereby, the opening 30 can be easily formed. In particular, in the vicinity of the outside 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 that prevents the gasket from being removed. Although 48b is provided on both sides of the opening 48a for inserting the gasket, it is formed by forcibly releasing in the front-rear direction (up and down in FIG. 6).

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

However, 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 by die cutting, whereby the opening 30 is formed in the inner plates 14 and 19. Therefore, the opening 30 can be formed easily and inexpensively with a simple mold in which the opening 30 is released only in the front-rear direction.
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 the same degree of gradient.

  In addition, in the refrigerator having the above-described 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. Thereby, the shade 45 hardly protrudes outward from the throat portions 23 and 24 of the doors 2 and 17, and can be suppressed to the minimum necessary for preventing the leakage of cold air and ensuring the width of the pocket portions 25 and 26. , 17 can be accommodated in the gap between the throat portions 23, 24 and the inner side surface of the main body 1, and the throat portions 23, 24 of the doors 2, 17 and the inner side surface of the main body 1 can be accommodated. Therefore, it is possible to eliminate the need to increase the gap between the pockets 25 and 26 and prevent the cold air from leaking and securing the lateral width of the pocket portions 25 and 26.

  7 and 8 show the second and third embodiments. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only the part is described.
