Description

Embodiments of the present invention relate to storage.

Conventionally, in a storage such as a refrigerator, a freezer, or a hot storage, an internal light for illuminating the storage room in the refrigerator is provided. This interior light is provided on the wall surface of the room such as the side surface and the back surface of the storage room, and the storage room is illuminated from the wall surface of the room.

However, in such a case where the storage room is illuminated from the wall surface of the storage room, the storage item may be placed in the vicinity of the interior light, in which case the lighting is blocked by the storage item and the illuminance to the storage room is increased. The drop will be greater. In addition, in the case where the interior light is provided in the back of the storage room, the irradiation light directly enters the eyes of the user who opens the door and looks into the storage room, and it feels dazzling.
On the other hand, there is a throat portion provided on the back surface of the door facing the storage chamber with an internal light (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 11-83306

In the case where the interior light is provided in the throat of the door as described above, the stored items are not placed in the vicinity of the internal light when the door is opened, and therefore the lighting is not obstructed by the stored items. , The decrease in illuminance for the storage room does not increase significantly. In addition, the irradiation light does not directly enter the eyes of the user who opens the door and looks into the storage room, and it is less likely to be dazzled.

However, when the door is opened, the irradiation light of the interior light is reflected by illuminating the glossy leading edge decoration of the shelf existing in the storage room, which is dazzling to the user's eyes. This is a problem that arises because the interior light is installed in the throat of the door to illuminate the storage room from the front side when the door is opened. This is a problem that does not occur if the storage room is illuminated from the side or the back side.

Therefore, by installing a lighting device in the throat part of the door, even if the irradiation light is reflected by the leading edge decoration of the shelf of the storage room, it provides a storage that does not get in the eyes of the user and feel dazzling. do.

The storage of the present embodiment has a storage chamber inside, a storage body having an opening leading to the storage room in the front, and a back surface facing the storage room, which is provided so as to open and close the opening of the storage body. A door having a throat part in the part, a lighting device provided in the throat part of this door to illuminate the storage room when the door is opened, and a front edge decoration provided in the storage room to reflect light to the front edge part. The lighting device is composed of an LED and a shade covering the LED, and the light emitted from the LED is tilted in the vertical direction by passing through the shade.

The foam insulating material 19 is filled between the 17 and the inner plate 18.

That is, the opening 8 on the front surface of the refrigerating chamber 6 is opened and closed by two doors, the door 2 and the door 16, and although not shown in detail, the left end of the door 2 is pivotally supported by the storage body 1. The door 16 has a right end portion pivotally supported on the main body 1 and is provided so as to be openable and closable in a hinged door type and a double door type that rotates around each of the shaft support portions. A partition member 20 between the left and right sides 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 back surfaces of the inner plates 14 and 18, which are the back surface portions facing the refrigerating chamber 6, respectively. As represented by the throat portion 21 of the door 2, these throat portions 21 and 22 project from the peripheral portions of the back surfaces of the inner plates 14 and 18 in a rectangular frame shape, and are hollow. be. Further, pocket portions 23 and 24 are provided in a plurality of stages in each surrounding space of these throat portions 21 and 22 (pocket portions 24 are shown in FIG. 2). Lighting devices 25 and 26 are provided in the upper and lower intermediate portions of one side portion extending in the vertical direction on each of the shaft support portions of the throat portions 21 and 22, respectively.

FIG. 4 shows the details of the lighting devices 25 and 26 represented by the lighting device 25 of the door 2, and the substrate holder 27 is incorporated in the throat portions 21 and 22. The substrate holder 27 has a shape that follows the inner surface of the throat portions 21 and 22 as a whole, and forms a container shape in which the front side (lower side in FIG. 4) is open and the rear side (same upper side) is closed. It is fixed to the inner surface of the throat portions 21 and 22. Further, the substrate holder 27 is gray and has a light-shielding property as a whole, and has an opening 28 on the outer surface portion facing the outside of the throat portions 21 and 22 (the side opposite to the pocket portions 23 and 24 sides). An opening 29 having almost the same size and shape is formed on the outer side of the throat portions 21 and 22 corresponding to the opening 28. 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 surface of the outer plates 13 and 17, and the base portion 31a is fixed and fixed to the inner surface 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 (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 the 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, foamed polyurethane) 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 seal 35 is attached to the opening edge portion on the front side 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 (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 pressure-contacting 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 refrigerating chamber 6 is tilted in the vertical direction, and in particular, it 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 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 detecting 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 microswitches. 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 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 the stored items are not placed in the vicinity of the lighting device when the 16 is opened, the lighting is not obstructed by the stored items, and therefore, the decrease in the 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, the lighting devices 25 and 26 are provided in the throat portions 21 and 22 of the doors 2 and 16 as described above, and the refrigerating chamber 6 is illuminated from the front side when the doors 2 and 16 are opened. You can solve the problem.

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 on the pocket portions 23 and 24 sides, 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 section 21 and 22, the interior light must be made smaller, and this small interior light has low brightness and is sufficient. 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 also becomes strong, but in the refrigerator having the above configuration, it is irradiated to the refrigerating chambers 6 of the lighting devices 25 and 26. 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.

If the lighting devices 25 and 26 in the refrigerator (storage) having the above configuration have a camera for taking a picture of the inside of the refrigerator, the lighting by the lighting can be taken when the inside of the refrigerator is taken by interlocking the lighting devices 25 and 26 when the camera is operated. It is good to help with.
