Description

refrigerator

The present invention relates to a refrigerator having a lighting device in a storage compartment.

In the past, the illuminating device for the storage compartment of the refrigerator is proposed to be installed in the ceiling of the storage room, and is provided to illuminate the light in a direction slightly inclined toward the deep side (for example, see Patent Document 1).

[Prior patent documents] [Patent Literature]

[Patent Document 1] JP-A-2007-3037 (Page 3, Figure 2)

In the conventional lighting device of the refrigerator, the irradiation direction is substantially right or slightly inclined toward the depth side. Therefore, for example, when the food to be taken out is selected from the storage compartment, the light is not slightly taken out from the shelf of the storage compartment to the front side, and the indication of the food or the like is not seen. Therefore, in order to confirm the label, the user must take out the food from the storage room and expose it to the indoor lighting, and it is desirable to improve the convenience when the food is selected and taken out.

Moreover, the storage compartment of the conventional refrigerator is divided into upper by transparent shelves. Next, when a lot of food is placed on the transparent frame, the light from the lighting device disposed on the ceiling of the storage room is covered by the food, and the storage room is darkened, and the food is unclear.

The present invention has been developed in order to solve the problems as described above, and provides a refrigerator that can also illuminate food that is pulled out from the storage compartment to or from the front side. Further, a refrigerator is provided which can make the storage compartment brighter.

The refrigerator of the present invention comprises: a storage compartment; one or more frames are made of a material having light transmissivity, and the storage compartment is partitioned into upper and lower sides; the first lighting device is in the depth direction of the ceiling of the storage compartment. Provided on a front side of the center and irradiated with light directed in a direction earlier than the storage chamber; and a second illumination device disposed on a lower side than any one of the one or more frames and irradiated The light pointed in the direction before the storage compartment.

Since the present invention has the first illuminating device, the illuminating device is disposed on the front side of the ceiling in the depth direction of the storage compartment, and illuminates the light directed in the direction before the storage compartment is directly below, so the user When the food in the storage compartment is pulled out to the front side, at least a portion of the first lighting device illuminates the food. Therefore, the visibility when the food is taken out from the storage compartment can be improved.

Further, since the present invention has the second illuminating device, the illuminating device is disposed on the lower side than any one of the one or more frames, and illuminates the light pointed in the direction before the storage room, so the storage room is borrowed from the first illuminating device. The light from above is illuminated by light from below from the second illumination device. Since the storage compartment can be made bright, the visibility of the food in the storage compartment can be improved. also, For example, even if the light from the first illumination device is covered by the food placed on the shelf in the storage compartment, the lower side of the shelf can be illuminated by the second illumination device.

Further, the second illuminating device 40A is provided in a range of about 50% to about 90% of the width in the refrigerating compartment 5.

The second illuminating device 40A includes: an assembly substrate 45a, 45b (hereinafter referred to as an assembly substrate 45), a plurality of LED elements 41 that emit white light, a holding portion 43 that holds the plurality of assembly substrates 45, and a cover assembly The cover 44 of the substrate 45. Each of the assembly substrates 45 has a shape that is long in the width direction, and the plurality of assembly substrates 45 are arranged in series in the longitudinal direction in the holding portion 43. The plurality of assembled substrates 45 are disposed in a direction in which the longitudinal direction thereof coincides with the width direction of the refrigerator compartment 5. A wire for energization (not shown) is attached to the assembled substrate 45, and the state of energization of the assembled substrate 45 is controlled by a control device (not shown).

Since the second illuminating device 40A is attached to the lower side of the refrigerating chamber 5, the light from the second illuminating device 40A is irradiated upward from the lower portion of the back surface of the refrigerating chamber 5, and is irradiated into the refrigerating chamber 5.

[action]

Hereinafter, the operation of the refrigerator 1 of the second embodiment configured as described above will be described.

In the refrigerator compartment 5, a door opening/closing sensor (not shown) that detects the opening and closing state of the refrigerator compartment door 7 is provided, and when the refrigerator compartment door 7 is closed, the assembled substrates 35 and 45 are not energized, and the light is not irradiated. In the refrigerator compartment 5. When the refrigerating compartment door 7 is opened, the forward current flows to the assembly substrates 35, 45, and white light is emitted from the LED elements 31, 41. The white light emitted from the LED elements 31 and 41 passes through the covers 34 and 44 and is irradiated into the refrigerator compartment 5. The light that has passed through the refrigerating compartment 5 passes through the translucent transparent frame 20, and then the food placed on the transparent frame 20 is irradiated. Since the first illuminating device 30A and the second illuminating device 40A are disposed in a wide range of about 50% to about 90% of the width in the refrigerating chamber 5, the side wall side light of the left and right sides of the refrigerating chamber 5 is easily accessible. Further, the inside of the refrigerating compartment 5 is made brighter.

The light from the first illuminating device 30A is irradiated on the front side from the front side of the first illuminating device 30A in a direction from 1° to 5° (for example, 1°). Therefore, when the user pulls the food in the refrigerating compartment 5 from the transparent frame 20 to or from the front side, since at least a part of the light from the first illuminating device 30A illuminates the food that is pulled or pulled, the transparent frame The visibility of the 20 foods that are pulled out or pulled closer is improved. Therefore, in order to confirm the labeling of the food, it is easy to confirm even if the user does not completely take out the food from the refrigerating compartment 5 and shines indoor lighting. Food labeling, etc., and easy to use.

Moreover, the light from the second illuminating device 40A is irradiated into the refrigerator compartment 5 from the lower side of the back side in the refrigerator compartment 5 upward. Therefore, the inside of the refrigerating compartment 5 is irradiated with light from above by the first illuminating device 30A and light from below by the second illuminating device 40A. Thus, for example, a plurality of food products are placed on the upper transparent frame 20, and light from the first illumination device 30A is covered by the food product, and the lower side of the transparent frame 20 is also borrowed from the second illumination device 40A. Illuminated by light.
