Further, a substrate holding claw 30 is provided inside the inner side surface portion of the substrate holder 27 facing the opening 28.

On the other hand, the connector housing 31 is incorporated in the outer plates 13 and 17 of the doors 2 and 16. In the connector housing 31, the base portion 31a is attached to the inner surfaces of the outer plates 13 and 17, and the base portion 31a is fixed and fixed to the inner surfaces of the outer plates 13 and 17. A rectangular parallelepiped case portion 31b is formed behind the base portion 31a of the connector housing 31 (upper in FIG. 4), and a lead wire is inserted in the center of the rear wall portion of the case portion 31b. A hole 31c is formed, and the lead wire 33 is tightly inserted into the lead wire insertion hole 31c via a seal 32. That is, the lead wire insertion hole 31c of the case portion 31b is sealed by the seal 32 in a state where the lead wire 33 is inserted.

The lead wire 33 supplies power from the main body 1 through the shaft support portion of the door 2, and has a connector 34 on the input side at a tip portion located outside the case portion 31b (board holder 27 side). ..
The lighting device 26 of the door 16 is provided with a structure symmetrical to that of the lighting device 25 of the door 2.

With this configuration, the foamed heat insulating materials 15 and 19 (for example, polyurethane foam) are injected into the outer plates 13 and 17, and the inner plates 14 and 18 are combined and bonded to the outer plates 13 and 17. At this time, a sticker 35 is attached to the opening edge on the front side of the substrate holder 27, and the sticker 35 is attached to the rear surface of the case portion 31b of the connector housing 31 (the peripheral portion of the lead wire insertion hole 31c). The inside of the substrate holder 27 is tightly sealed from the inside of the outer plates 13 and 17 by being pressed against the substrate holder 27. As a result, the foamed heat insulating materials 15 and 19 injected into the outer plates 13 and 17 do not invade the inside of the substrate holder 27, and are between the outer plate 13 and the inner plate 14 at the door 2 and outside at the door 16. It is filled between the plate 17 and the inner plate 18, respectively.

After that, the output side connector 39 provided at the tip of the lead wire 38 of the circuit board 37 on which the LED 36 which is the light source of the lighting devices 25 and 26 is mounted is connected to the input side connector 34, and the circuit board 37 is connected. Is engaged with the substrate holding claw 30 from the opening 28 of the substrate holder 27 and mounted. Then, a shade 40 is attached to the opening 28 of the substrate holder 27 to close the openings 28 and 29.
The surplus space of the throat portions 21 and 22 is loaded with a heat insulating material 41 such as Styrofoam.

FIG. 1 shows the door 2 in which the lighting device 25 is incorporated as described above in an open state, and as shown by an arrow L in FIG. 1, the shade 40 is passed through the LED 36 of the lighting device 25. The irradiation angle of the light radiated to the refrigerator compartment 6 is tilted in the vertical direction, and in particular, is tilted downward (the same applies to the door 16 side, although not shown).

This irradiation angle L is realized by tilting the circuit board 37 in the same direction and installing the circuit board 37. In addition, the circuit board 37 does not tilt and refracts light in the shade 40 in the same direction. Or by using a bullet-shaped LED 36 with long legs (leads) and bending one of the legs, for example, the LED 36 can be mounted at an angle in the same direction, or it can be mounted on the circuit board 37 in small numbers. It can also be realized by using the separated ones and tilting them in the same direction.

Further, FIG. 2 shows switches 42 and 43 which are door open / close detection means provided in the heat insulating wall of the refrigerator body 1 corresponding to the lighting devices 25 and 26, and these are, for example, tact switches and micro switches. Although not shown in detail, both of the protrusions protruding inside the main body 1 are pressed by the throat portions 21 and 22 (one side of each shaft support portion) due to the closing of the doors 2 and 16. The closing of the doors 2 and 16 is detected, and the pressing of the protrusion is released by the closing of the doors 2 and 16, so that the opening of the doors 2 and 16 is detected. The lighting devices 25 and 26 cause the LED 36 to emit light when the switches 42 and 43 detect the opening of the doors 2 and 16, and extinguish the LED 36 when the switches 42 and 43 detect the closing of the doors 2 and 16.

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 16 are opened, the switches 42 and 43 detect the opening of the doors 2 and 16 to cause the LED 36 of the lighting devices 25 and 26 to emit light. As shown in S2, the refrigerator compartment 6 is illuminated.

Further, in this case, when only one of the doors 2 and 16 is opened, the opened door-side switch among the switches 42 and 43 detects the opening of the door, so that the lighting devices 25 and 26 are opened. The LED 36 of the lighting device on the door side is made to emit light, and the refrigerating room 6 is illuminated as represented by the case where the door 16 is opened in FIG. That is, in this case, only the LED 36 of the lighting device on the open door side of the doors 2 and 16 is made to emit light, and the LED 36 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 25 and 26 are provided in the throat portions 21 and 22 of the doors 2 and 16, 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 device when 16 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, and Since the irradiation light does not directly enter the eyes of the user who opens the doors 2 and 16 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, the irradiation angle of the lighting devices 25 and 26 with respect to the refrigerating chamber 6 is tilted in the vertical direction, whereby the irradiation light is reflected by the front edge decoration 10a of the shelf 10 of the refrigerating chamber 6. Even if it is done, it can be prevented from being dazzled by the user's eyes. That is, it is because the lighting devices 25 and 26 are provided in the throat portions 21 and 22 of the doors 2 and 16 as described above so that the refrigerating chamber 6 is illuminated from the front side when the doors 2 and 16 are opened. The problem can be solved.

Further, in the refrigerator having the above configuration, the irradiation angle of the lighting devices 25 and 26 with respect to the refrigerating chamber 6 is tilted downward even in the vertical direction, whereby the stored items placed on the shelf 10 are placed on the lower side. It is possible to illuminate more effectively from above than to illuminate from above, and to distinguish it more clearly.

In addition, the board holder 27 on which the circuit board 37 on which the LED 36 is mounted has a light-shielding property as a whole, whereby the board holder 27 and the connector in the throat portions 21 and 22 are generated by the light when the LED 36 emits light. It is possible to prevent parts such as 39 and 34 from being seen through the side walls of the throat portions 21 and 22, particularly the pocket portions 23 and 24, and it is possible to enhance the commercial value. The light-shielding property of the substrate holder 27 may be provided only on the pocket portions 23 and 24, not on the entire substrate holder 27.

In addition, in the refrigerator having the above configuration, the LED 36 is used as the light source of the lighting devices 25 and 26, and the LED 36 has high brightness and can be made thin in bulk, and the thin throat portion 21, It can be easily incorporated into 22. By the way, in the case of a conventional interior light (fluorescent lamp), in order to incorporate it into the thin throat sections 21 and 22, the interior light must be made smaller, and this small interior light is sufficient because the brightness is low. It is not possible to obtain a good lighting effect. In that respect, in the refrigerator having the above configuration using the LED 36 as the light source of the lighting devices 25 and 26, it can be easily incorporated into the thin throat portions 21 and 22, and the brightness is high, so that a sufficient lighting effect can be obtained. Can be done.

Further, due to the high brightness of the LED 36, the reflected light from the front edge decoration 10a of the shelf 10 of the refrigerating chamber 6 becomes strong, but in the refrigerator having the above configuration, the refrigerating chambers 6 of the lighting devices 25 and 26 are irradiated with the reflected light. By tilting the angle in the vertical direction, it is possible to prevent the reflected light from entering the user's eyes and making it feel dazzling.

The lighting devices 25 and 26 in the refrigerator (storage) having the above configuration have a camera for photographing the inside of the refrigerator. It is good to help with.

The storage described above is not limited to the above-described embodiment, and is appropriately changed as long as it does not deviate from the gist, such as being applicable to storages other than refrigerators, such as freezers and warmers. Can be carried out.
