JP-A-11-83306

  In the above-described configuration in which the interior light is provided in the throat portion of the door, the storage item is not placed near the interior light when the door is opened, and therefore, the illumination is not blocked by the storage item. However, the decrease in illuminance for the storage room does not increase. Further, the irradiation light does not directly enter the eyes of the user who opens the door and looks into the storage room, so that the user is less likely to feel dazzling.

  However, when the door is opened, the illumination light of the interior light is reflected on the glossy front edge decoration of the shelf existing in the storage room, and the reflected light enters the eyes of the user and is dazzled. This is a problem that arises because the interior light is provided in the throat part of the door and the storage room is illuminated from the front side when the door is opened, and the interior light is installed on the wall surface of the storage room. This is a problem that does not occur when the storage room is provided to illuminate the storage room from the side or the back side.

  Therefore, a lighting device is provided at the throat of the door to provide a storage room in which even if the irradiation light is reflected by the front edge decoration of the shelf in the storage room, it does not enter the eyes of the user and feel dazzling. I do.

  The storage of the present embodiment has a storage room inside, a storage body having an opening communicating with the storage on the front surface, and a rear surface provided to open and close the opening of the storage body and facing the storage room. A door having a throat portion at a portion thereof, a lighting device provided at the throat portion of the door and illuminating the storage room when the door is opened, and a front edge decoration provided at the storage room and reflecting light at a front edge portion The illumination device includes an LED and a shade that covers the LED, and light emitted from the LED is inclined vertically by transmitting the shade.

The outer plate 17 is combined with an inner plate 18. A foam insulating material 19 is filled between the inner plate 17 and the inner plate 18.

  That is, the opening 8 on the front surface of the refrigerating compartment 6 is opened and closed by two doors, a door 2 and a door 16. Although not shown in detail, the left end of the door 2 is pivotally supported by the refrigerator main body 1. The door 16 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, each of which pivots around the respective shaft supporting portion. In addition, the left and right partition member 20 is attached to the left door 2 with a movable structure that does not hinder the opening of the door 2.

  The doors 2 and 16 have throat portions 21 and 22 on the rear surfaces of the inner plates 14 and 18 which are the rear portions facing the refrigerator compartment 6, respectively. These throat portions 21 and 22 protrude in a rectangular frame shape from the peripheral portions of the back surfaces of the inner plates 14 and 18 as shown by the throat portion 21 of the door 2 in FIG. is there. In each surrounding space of the throat portions 21 and 22, pocket portions 23 and 24 are provided in a plurality of stages (the pocket portion 24 is shown in FIG. 2). Lighting devices 25 and 26 are provided at upper and lower middle portions of one side portion of the throat portions 21 and 22 extending in the vertical direction on the side of each shaft support portion.

  FIG. 4 shows the details of the lighting devices 25 and 26 as a representative of the lighting device 25 of the door 2, and a substrate holder 27 is incorporated in the throat portions 21 and 22. The substrate holder 27 has a shape that follows the inner surfaces of the throat portions 21 and 22 as a whole and has a container shape in which the front side (the lower side in FIG. 4) is open, the taper is closed, and the rear side (the upper side) is closed. And is fixedly fixed to the inner surfaces of the throat portions 21 and 22. The substrate holder 27 is, for example, gray and has a light-shielding property as a whole, and has an opening 28 in an outer surface facing the outside of the throat portions 21 and 22 (the side opposite to the pocket portions 23 and 24). An opening 29 having substantially the same size and the same shape as that of the opening 28 is formed on the outside of the throats 21 and 22 corresponding to the opening 28. Further, a substrate holding claw 30 is provided inside the inner side surface of the substrate holder 27 facing the opening 28.

  On the other hand, a connector housing 31 is incorporated inside the outer plates 13 and 17 of the doors 2 and 16. In the connector housing 31, the base 31a is attached to the inner surfaces of the outer plates 13 and 17, and the base 31a is fixedly fixed to the inner surfaces of the outer plates 13 and 17. Further, a rectangular parallelepiped case portion 31b is formed behind the base portion 31a of the connector housing 31 (upward in FIG. 4), and a lead wire is inserted through the rear wall portion of the case portion 31b substantially at the center. A hole 31c is formed, and a lead wire 33 is densely 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 with the lead wire 33 inserted.

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

  In this configuration, the foam insulation 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 with the outer plates 13 and 17 and joined. At this time, a seal 35 is attached to the front opening edge of the substrate holder 27, and the seal 35 is attached to the rear surface of the case portion 31b of the connector housing 31 (a portion around 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. As a result, the foamed heat insulating materials 15 and 19 injected into the outer plates 13 and 17 do not enter the inside of the substrate holder 27, and are located between the outer plate 13 and the inner plate 14 in the door 2 and outside in the door 16. The space between the plate 17 and the inner plate 18 is filled.

Thereafter, an output-side connector 39 provided at the end of a lead wire 38 of a circuit board 37 on which an LED 36 as a 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 attached to the substrate holder 27 through the opening 28 of the substrate holder 27. 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 filled with a heat insulating material 41 such as styrene foam.

  FIG. 1 shows the door 2 in which the lighting device 25 is incorporated in an open state as described above, and as shown by an arrow L in FIG. The irradiation angle of the light radiated to the refrigerator compartment 6 is inclined in the up and down direction, and in particular, is inclined downward (the same is applied to the door 16 side, though not shown).

  The irradiation angle L is realized by installing the circuit board 37 in the same direction and tilting the circuit board 37. In addition, the circuit board 37 is not tilted and the light is refracted by the shade 40 in the same direction. The LED 36 can be mounted in a slanted shape with long legs (leads), for example, by bending one of the legs so that the LED 36 is tilted in the same direction. It can also be realized by using divided parts and installing them by tilting them in the same direction.

  FIG. 2 shows switches 42 and 43 which are door opening / closing detecting means provided in the heat insulating wall of the cabinet main body 1 corresponding to the lighting devices 25 and 26. These are, for example, tact switches and micro switches. Although not shown in detail, the protruding members, both of which protrude into the storage body 1, are pressed by the throat portions 21, 22 (one side portion of each pivot portion) by closing the doors 2, 16, The closing of the doors 2 and 16 is detected, and the opening of the doors 2 and 16 is detected by releasing the pressing of the protrusion by the closing of the doors 2 and 16. The lighting devices 25 and 26 emit light when the switches 42 and 43 detect the opening of the doors 2 and 16, and turn off the LED 36 when detecting 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, thereby causing the LEDs 36 of the lighting devices 25 and 26 to emit light. As shown in S2, the refrigerator compartment 6 is illuminated.

  In this case, when only one of the doors 2 and 16 is opened, one of the switches 42 and 43 on the side of the opened door detects the opening of the door, so that one of the lighting devices 25 and 26 is opened. The LED 36 of the lighting device on the door side is turned on to illuminate the refrigerator compartment 6 as representatively shown in FIG. 6 when the door 16 is opened. 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. As a result, power consumption is reduced.

  In the refrigerator having the above-described configuration, the lighting devices 25 and 26 are provided on the throat portions 21 and 22 of the doors 2 and 16, respectively. Since the storage items are not placed near the lighting device when opening 16, the illumination is not obstructed by the storage items, so that the illuminance of the refrigerator compartment 6 does not significantly decrease, and Irradiation light does not enter the eyes of the user who opens the doors 2 and 16 and looks into the refrigerating room 6, and the user is less likely to feel dazzling.

  In addition, in the refrigerator having the above-described configuration, the irradiation angles of the lighting devices 25 and 26 with respect to the refrigerator 6 are inclined in the vertical direction, whereby the irradiation light is reflected by the front edge decoration 10 a of the shelf 10 of the refrigerator 6. Even if it is done, it can be prevented from getting into the eyes of the user and feeling dazzling. That is, the illuminating devices 25 and 26 are provided on the throat portions 21 and 22 of the doors 2 and 16 so that the refrigerator compartment 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 angles of the lighting devices 25 and 26 with respect to the refrigerator compartment 6 are inclined downward in the vertical direction, whereby the stored items placed on the shelf 10 can be moved downward. It is possible to illuminate more effectively from the upper side than to illuminate from above, and the distinction can be made more clearly.

  In addition, the substrate holder 27 on which the circuit board 37 on which the LEDs 36 are mounted is light-shielding as a whole, so that when the LEDs 36 emit light, the light causes the substrate holder 27 in the throat portions 21 and 22 and the connector 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 side walls of the pocket portions 23 and 24, thereby improving the commercial value. The light-shielding properties 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 a light source of the lighting devices 25 and 26. The LED 36 has high brightness and can be bulky and thin. 22 can be easily incorporated. By the way, in the case of a conventional interior light (fluorescent light), in order to incorporate it into the thin throat portions 21 and 22, the interior light has to be reduced, and the small interior light has low luminance and is sufficiently low. Lighting effects cannot be obtained. On the other hand, in the refrigerator having the above-described 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.

  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 refrigerator compartment 6 also becomes strong, but in the refrigerator having the above-described configuration, the light is radiated to the refrigerator compartment 6 by the lighting devices 25 and 26. By tilting the angle in the vertical direction, the reflected light can be prevented from entering the user's eyes so that the user does not feel dazzling.

  In the refrigerator (storage) having the above configuration, the lighting devices 25 and 26 each include a camera for photographing the inside of the refrigerator. When the cameras are operated, the lighting devices 25 and 26 are linked to each other so that the illumination by the lighting is performed during the photographing in the refrigerator. It is good to help.

  The storage described above is not limited only to the above-described embodiment, and can be appropriately changed without departing from the gist, such as being applicable to a storage other than a refrigerator, such as a freezer or a hot storage. Can be implemented.

  In addition, although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The new embodiment can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and their equivalents.
