Description

  Embodiments of the present invention relate to a refrigerator.

  Conventionally, in a refrigerator, it has been considered to provide a lighting device at an end portion of a shelf that divides the inside of a storage (see, for example, Patent Document 1). However, in this case, sufficient light can not reach the area facing the end where the lighting device is disposed, and the visibility of stored products such as food and food stored in the storage is sufficiently enhanced. Is difficult. In order to improve visibility, it may be conceivable to arrange the lighting device at the center of the shelf or the like, but this reduces the storage height of the storage at the location where the lighting device is arranged, and the storage performance of the storage decreases. Another problem arises.

  Subsequently, specific configurations of the lighting device 14 and the shelf board 11 d will be described with reference to FIGS. 3 and 4. As shown in FIGS. 3 and 4, the lighting device 14 includes a plurality of LEDs 31, an LED substrate 32 on which the LEDs 31 are mounted, an LED substrate fixture 33, a substrate fixing tape (not shown), and a bundle of wires (not shown) Are configured as an LED unit equipped with the In addition, as shown to FIG. 3 and FIG. 4, the illuminating device 14 is comprised separately from the shelf board 11d.

  The LED substrate fixture 33 and the above-mentioned substrate securing tape are for securing the LED substrate 32 to the back wall of the refrigerator compartment 3. The LED substrate fixture 33 is made of metal in order to take measures against the heat generated from the LED 31. In this case, the LED substrate fixture 33 is formed by bending a metal plate so that the cross section becomes a U-shape.

  As shown in FIG. 4, in the lighting device 14 of this embodiment, a plurality of, specifically, six LEDs 31 are arranged in one line at equal intervals. The number, arrangement, and the like of the LEDs 31 may be set optimally in accordance with the specifications of the illumination device 14 such as the irradiation distance and the irradiation angle of the LEDs 31 and the desired illumination range.

  In this case, the lighting device 14 is configured to turn on (on) and turn off (off) the plurality of LEDs 31 collectively. The lighting device 14 may selectively turn on / off the plurality of LEDs 31. In this way, it becomes possible to select and illuminate only a desired part of the illumination range of the illumination device 14.

  As shown in FIGS. 3 and 4, the lighting device 14 emits light toward the inside of the shelf 11 d from the side of the shelf 11 d, specifically, the side on the rear side of the cold storage room 3 (main body 2). It is arranged as. Further, in this case, on the upper surface of the shelf plate 11d, a irregular reflection area 34 for irregularly reflecting light is formed in the vicinity of the center of the refrigerator 1 in the front-rear direction (left and right direction in FIG. 3). The irregular reflection area 34 is formed by asperities representing characters (for example, "COOL"), and the interval between the asperities is wider as the distance from the lighting device 14 is longer.

  The irregular reflection area 34 can be formed by affixing the seal or the sheet having the unevenness to the shelf board 11 d. The irregular reflection area 34 can also be formed by subjecting the shelf plate 11 d to a process (for example, embossing) to impart the above-mentioned unevenness. The irregular reflection area 34 may be formed on the lower surface of the shelf 11 d instead of or in addition to the upper surface of the shelf 11 d. In addition, the irregular reflection area 34 may be formed by an unevenness representing a figure instead of or in addition to the unevenness representing a character.

  In this case, as shown in FIG. 3 and FIG. 4, among the four side surfaces of the shelf board 11 d, the reflecting members 35 for reflecting light are disposed on the three side surfaces except the side surface on which the lighting device 14 is disposed. It is done. The reflecting member 35 is, for example, an aluminum tape or the like, and is attached so as to cover only the three side surfaces of the shelf board 11 d.

Next, illumination by the illumination device 14 configured as described above will be described.
According to the above configuration, the light emitted from the illumination device 14 is guided (guided) to the inside of the shelf 11 d which is a transparent member. Then, the light guided to the inside of the shelf board 11d is irregularly reflected in the irregular reflection area. In this case, since the irregular reflection area 34 is formed on the upper surface of the shelf plate 11d, the entire reflected material placed above the shelf plate 11d, ie, the entire storage material placed on the shelf plate 11d, is uniformly illuminated by the irregularly reflected light. Can. In the case where the irregular reflection area 34 is formed on the lower surface of the shelf 11 d, the light reflected irregularly can illuminate the lower side of the shelf 11 d, that is, the inside of the chilled chamber 12 uniformly over a wide range.

  As described above, the irregular reflection area 34 is formed, for example, by the unevenness representing the character "COOL". Therefore, in a state where light is emitted from the lighting device 14, as shown in FIG. 5, the character “COOL” is floated by the light irregularly reflected in the irregular reflection area 34, and the user can recognize the character. .

  On the other hand, in the state where light is not emitted from the lighting device 14, as shown in FIG. 6, the characters “COOL” do not appear. FIGS. 5 and 6 and later-described FIGS. 8 and 9 are views for explaining the display mode to the last, and do not accurately represent the actual display mode. In this case, in FIG. 5 and the like, the part that is particularly emitting light is expressed in black, and the other parts are expressed in white.

  As explained above, in the refrigerator 1 of this embodiment, the shelf board 11d which comprises the ceiling of the chilled chamber 12 is comprised by the permeation | transmission member, and it is provided in a store | warehouse and open | releases at least one side among the door 3a and the door 3b. The illumination device 14 that lights up occasionally is provided to emit light toward the inside of the shelf 11 d from the side surface of the shelf 11 d. And the irregular reflection area | region 34 which diffusely reflects light is formed in the shelf 11d.

  According to such a configuration, when the irregular reflection area 34 is formed on the upper surface of the shelf board 11d, the whole of the irregular reflection area 34 is evenly distributed regardless of the arrangement of the stored products placed on the shelf board 11d. It can be illuminated. Further, according to the above configuration, when the irregular reflection area 34 is formed on the lower surface of the shelf board 11 d, the inside of the chilled chamber 12 can be illuminated uniformly over a wide range. And, in this case, since the lighting device 14 is provided on the back side of the shelf board 11 d, the storage height of the storage of the shelf board 11 d is not reduced by the lighting device 14. Therefore, according to the present embodiment, the excellent effect of being able to enhance the visibility of the stored matter can be obtained while maintaining the storage property of the stored matter well without reducing it.

  The irregular reflection area 34 can be formed by asperities representing one or both of characters and figures. Here, if a character to be notified to the user is adopted as the above character, when the user opens the doors 3a and 3b, the control unit 20 does not perform a dedicated processing for notification as in the conventional lighting device. The character or figure can be easily notified to the user simply by executing the process for lighting 14.

  In the present embodiment, the shelf board 11 including the shelf board 11 d and the lighting device 14 are separately configured. According to such a configuration, as in the conventional refrigerator, the shelf board 11 can be easily removed. Therefore, according to the configuration of the present embodiment, the user can easily perform the cleaning operation of the shelf board 11.

  In the present embodiment, among the four side surfaces of the shelf board 11d, the reflecting members 35 for reflecting light are disposed on the three side surfaces other than the side surface on which the lighting device 14 is disposed. According to such a configuration, among the light irradiated from the illumination device 14, the light transmitted without irregular reflection in the irregular reflection area 34, the light irradiated in a direction different from the irregular reflection area 34, etc. It is possible to reflect light, and the reflected light can be diffusely reflected by the diffuse reflection area 34. Therefore, according to the present embodiment, it is possible to suppress the output (input) of the illumination device 14 to a low level while maintaining the same degree of illumination effect as compared with the configuration in which the reflection member 35 is not disposed. Power consumption of 1 can be reduced.

  The reflecting member 35 is provided to cover only the side surface of the shelf board 11 d. In other words, the reflecting member 35 is not provided to cover the upper surface and the lower surface of the shelf board 11d. According to such a configuration, when light is emitted from the lighting device 14, light emission is generated along the outer shapes (squares) of the upper surface and the lower surface of the shelf board 11d, so that an effect of improving the appearance can be obtained. .

  In the present embodiment, the interval (rough / dense) of the unevenness (shrinking) of the irregular reflection area 34 changes in accordance with the distance from the illumination device 14. Specifically, the shorter the distance from the lighting device 14 is, the narrower the spacing of the concavities (dense), and the longer the distance from the lighting device 14, the wider the spacing of the concavities (rough). In this way, the intensity of the diffusely reflected light becomes uniform in the diffuse reflection area 34 independently of the distance from the lighting device 14, and the brightness of the character that is floated up by the diffusely reflected light is made uniform. it can.

  The reflecting member 35 in the first and second embodiments may be disposed on at least one of the four side surfaces of the shelf board 11 d except the side surface on which the lighting device 14 is disposed. Even with such a configuration, at least a part of the light emitted from the lighting device 14 can be reflected, so that the effect of suppressing the output of the lighting device 14 can be obtained. Further, the reflecting member 35 may be arranged to cover one or both of the upper surface and the lower surface in addition to the side surface of the shelf board 11d. According to this configuration, although the effect of improving the aesthetic appearance described above can not be obtained, the effect obtained by reflecting light is not impaired. Furthermore, the reflecting member 35 may be provided as needed, and can be omitted.

As LED31 of the illuminating devices 14 and 53, you may use what can change the luminescent color. In this way, it is possible to change the color of the illumination according to the temperature of the place illuminated by the illumination devices 14 and 53. For example, depending on the temperature in the refrigerator compartment 3, the color of the illumination can be changed stepwise or continuously as described below.
Temperature in the refrigerator compartment 3: 20 ° C or more ... Luminous color: Red Temperature in the refrigerator compartment 3: 10 ° C or more and less than 20 ° C ... Luminescent color: orange Temperature in the refrigerator compartment 3: 7 ° C or more and less than 10 ° C ... Luminescent color: Yellow Temperature in cold storage room 3: less than 6 ° C. ... Luminescent color: white In this way, the user intuitively recognizes the difference in temperature of the illuminated part from the difference in color of illumination be able to.
