Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, from the perspective of energy conservation and the like, LED has been increasingly used as a light source for the lighting device inside the cabinet of a refrigerator. Generally, the light emitted from an LED has higher directivity compared to the light from a fluorescent lamp or the like. Therefore, when a plurality of LEDs are arranged on the inner wall of the storage compartment, the optical paths from the individual LEDs can be clearly visually recognized. In addition, since an LED is a point light source composed of small light-emitting elements, there is a tendency for the difference in light-emitting intensity to be large between the light-emitting part and its surroundings.

[0005] Thus, when LEDs are used for the lighting inside the cabinet of a refrigerator, uneven brightness is likely to occur depending on the location in the storage compartment. Also, depending on the location where the LEDs are arranged, a specific area may emit strong light, causing the user who opens the refrigerator door to feel dazzled.

[0006] The present invention aims to provide a refrigerator that can reduce unevenness in brightness when illuminating the interior using LEDs. [Means for solving the problem]

[0007] A refrigerator according to one aspect of the present invention comprises an inner box forming the inner wall of a storage space, a duct forming member provided at the rear of the storage space and forming a cold air passage, and an LED positioned on the rear side of the side surface of the duct forming member. In this refrigerator, light emitted from the LED is reflected by the inner box and irradiated into the storage space. [Effects of the Invention]

[0008] According to one aspect of the present invention, it is possible to provide a refrigerator that can reduce unevenness in brightness when illuminating the interior using LEDs. [Brief explanation of the drawing]

[0010] The embodiments of the present invention will be described below with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0011] <First Embodiment> (Overall configuration of the refrigerator) First, the overall configuration of the refrigerator 1 according to the first embodiment will be described. Figure 1 shows the external appearance of the refrigerator 1 and the configuration inside the refrigerator compartment 11. In Figure 1, the door of the refrigerator compartment 11 is not shown.

[0012] The exterior of refrigerator 1 is mainly composed of an insulated box 50. The insulated box 50 is mainly composed of an inner box 52, an outer box 51, and an insulating layer (not shown) formed between the inner box 52 and the outer box 51. This insulated box 50 forms the storage space of refrigerator 1. The inner box 52 forms the inner wall of the storage space. The inner box 52 is also called a food liner.

[0013] The storage space formed by the insulated box 50 is divided into multiple storage compartments by multiple partitions extending horizontally. For example, the storage space of refrigerator 1 is divided, from top to bottom, into a refrigerator compartment 11, a vegetable compartment, an ice-making compartment and a second freezer compartment, and a freezer compartment.

[0014] The refrigerator compartment 11 is provided with a pair of swing doors (not shown) divided into left and right sections. The vegetable compartment is provided with a drawer-type vegetable compartment door 12a. The freezer compartment is provided with a drawer-type freezer compartment door 13a. The ice-making compartment is provided with a drawer-type ice-making compartment door 14a. The second freezer compartment is provided with a drawer-type freezer compartment door 15a.

[0015] As described above, the refrigerator 1 according to the present embodiment is divided into a plurality of storage compartments, and a refrigerator compartment 11, a vegetable compartment, etc. are provided. However, the arrangement positions of the respective storage spaces are not limited thereto. Also, the configuration of the doors provided in each storage space is not limited to the above.

[0016] In the present embodiment, the surface on which the door is provided is referred to as the front or the front face of the refrigerator. And, based on the position that exists when the refrigerator 1 is installed in a normal state with the front face as a reference, each surface of the refrigerator 1 is defined as the upper surface, the side surface, the rear surface, and the bottom surface. Also, in the state where the refrigerator 1 is placed on the installation surface, the up-and-down direction of the refrigerator 1 is referred to as the vertical direction of the refrigerator 1. Also, in the state where the refrigerator 1 is placed on the installation surface, the front-and-back direction when the refrigerator 1 is viewed from the front is referred to as the front-and-back direction of the refrigerator 1. Further, the side located on the left when viewed from the front side of the refrigerator 1 is referred to as the left side of the refrigerator 1, and the side located on the right when viewed from the front side of the refrigerator 1 is referred to as the right side of the refrigerator 1.

[0017] Subsequently, the configuration inside the refrigerator compartment 11 will be described. A shower duct forming member 30 is provided at the back portion of the refrigerator compartment 11. The shower duct forming member 30 forms a shower duct 31 (see FIG. 3 etc.), which is a passage for cold air. The shower duct 31 communicates with the cooling chamber in which the cooler is arranged, and sends out the cold air cooled by the cooler to the refrigerator compartment 11. The shower duct forming member 30 is provided with a plurality of outlets for blowing cold air into the refrigerator compartment 11 (for example, a front outlet 32, a side outlet 33, etc.).

[0018] The refrigerator compartment 11 is equipped with lighting to illuminate the interior. In this embodiment, two types of lighting are provided: a ceiling light 58 and a rear light 40. The ceiling light 58 is located on the upper surface of the inner wall of the refrigerator compartment 11. The ceiling light 58 is composed of, for example, one or more LEDs. In another example, the ceiling light 58 may be composed of other lighting fixtures such as fluorescent lamps.

[0019] The rear light 40 is provided on the shower duct forming member 30. The rear light 40 has multiple LEDs 44 as light sources. The multiple LEDs 44 are arranged on the rear side (rear portion 52a side) of the side surface of the shower duct forming member 30. The detailed configuration of the rear light 40 will be described later.

[0020] One or more storage cases 55 are provided at the bottom of the refrigerator compartment 11.

[0021] (Regarding shower duct forming components) Next, we will describe the more detailed configuration of the shower duct forming member 30.

[0022] Figure 2 shows the external appearance of the shower duct forming member 30. Figure 3 shows the configuration of the rear side (the side on which the shower duct 31 is provided) of the shower duct forming member 30. Figure 4 shows the configuration of the side side (the side on which the rear light 40 is provided) of the shower duct forming member 30. Figure 5 shows the components of the shower duct forming member 30 in a disassembled state. Figure 6 shows the shower duct forming member 30 with the LED cover 43 removed.

[0023] The shower duct forming member 30 is positioned along the rear portion 52a of the inner box 52, which forms the inner wall on the rear side of the refrigerator compartment 11 (see Figure 4).

[0024] Multiple front outlets 32 are provided on the front portion 30a of the shower duct forming member 30, arranged vertically. The front outlets 32 communicate with the shower duct 31 and blow the cold air passing through the shower duct 31 towards the refrigerator compartment 11.

[0025] Multiple side outlets 33 are provided on the side portion 30b of the shower duct forming member 30, arranged vertically. In this embodiment, two side outlets 33 are provided on the left side portion 30b when viewed from the front, and two side outlets 33 are provided on the right side portion 30b when viewed from the front. The side outlets 33 are in communication with the shower duct 31 and blow the cold air passing through the shower duct 31 towards the refrigerator compartment 11.

[0026] Furthermore, a rear light 40 equipped with an LED 44 is provided on the rear side (rear side 52a side) of the side portion 30b of the shower duct forming member 30.

[0027] The shower duct forming member 30 mainly consists of a shower duct cover 21, an insulating member 22, a louver member 23, and a rear light 40 (see Figure 5).

[0028] The shower duct cover 21 forms the outer shape of the front side of the shower duct forming member 30. Here, the front side refers to the side located on the inside of the refrigerator compartment 11. In other words, the shower duct cover 21 forms the front portion 30a and the side portion 30b of the shower duct forming member 30.

[0029] The heat insulating member 22 is made of a highly heat insulating material, such as expanded polystyrene. The heat insulating member 22 is located on the back side (back side 52a side) of the shower duct cover 21. A concave groove extending in the vertical direction is formed on the back side of the heat insulating member 22. This groove is the shower duct 31 (see Figure 3). In addition, the heat insulating member 22 has holes or grooves that communicate with the shower duct 31 at positions corresponding to each front outlet 32 ​​and each side outlet 33.

[0030] With the above configuration, the insulating material 22 is positioned between the shower duct 31 and the refrigerator compartment 11, thereby improving the thermal insulation between the shower duct 31 and the refrigerator compartment 11.

[0031] The louver member 23 is installed to cover the upper of the multiple front outlets 32 provided in the shower duct cover 21. By installing the louver member 23, the direction of the air blown out from the front outlets 32 into the refrigerator compartment 11 can be restricted to a predetermined direction.

[0032] The rear lights 40 are provided along the left and right side portions 30b of the shower duct forming member 30. Each rear light 40 mainly consists of an LED substrate 41, an LED holding member (reflective member) 42, and an LED cover (diffusing member) 43.

[0033] The LED substrate 41 has an elongated, plate-like shape that extends in the vertical direction. Multiple LEDs 44 are arranged on one surface of the LED substrate 41 at predetermined intervals. In this embodiment, two LEDs 44 are scattered at three locations on one LED substrate 41 (i.e., the top, center, and bottom). That is, six LEDs 44 are provided on the left rear light 40 when viewed from the front, and six LEDs 44 are provided on the right rear light 40 when viewed from the front.

[0034] LED44 is the light source for the rear light 40. Each LED44 has a light-emitting diode element and is designed to emit light at a predetermined wavelength. The color of the LED44 can be changed as appropriate.

[0035] The LED holding member 42 holds the LED substrate 41. Figure 6 shows the state in which the LED substrate 41 is attached to the LED holding members 42 on both the left and right sides. With the LED substrate 41 attached to the LED holding member 42, the mounting surface of the LEDs 44 on the LED substrate 41 faces the front side (towards the refrigerator compartment 11).

[0036] The LED holding member 42 is formed of, for example, a resin material having light-shielding and light-reflecting properties. As a result, as will be described later, the light emitted from the LED 44 can be reflected by the LED holding member 42 and directed toward the rear part 52a of the inner box 52. For this reason, the LED holding member 42 is also called a reflective member. For example, the LED holding member 42 is formed of a white resin material.

[0037] The LED cover 43 is mounted so as to cover the LED substrate 41 attached to the LED holding member 42. The LED cover 43 is made of, for example, a resin material having light transmittance and light diffusion properties. This allows the light emitted from the LED 44 to be diffused and irradiated to the outside of the LED cover 43 (i.e., the refrigerator compartment 11 side), as will be described later. For this reason, the LED cover 43 is also called a diffusion member. For example, the LED cover 43 is made of a colorless, transparent resin material.

[0038] (Regarding the rear lights) Next, we will describe the configuration of the rear light 40 in more detail.

[0039] Figure 7 shows the external appearance of the LED holding member 42. Figure 7 shows the configuration of the LED holding member 42 on the side to which the LED substrate 41 is attached. Figures 8 and 9 show the external appearance of the LED cover 43. Figure 8 shows the configuration of the inside of the LED cover 43 (the side where the LED substrate 41 is located). Figure 9 shows the configuration of the outside of the LED cover 43 (the side facing the refrigerator compartment 11).

[0040] Figures 10, 11, and 12 show the cross-sectional configuration of the inner box 52 and the shower duct forming member 30. Figure 10 is a cross-sectional view of the shower duct forming member 30 shown in Figure 3 along line AA (i.e., the position where the LED 44 is located). Figure 11 is a cross-sectional view of the shower duct forming member 30 shown in Figure 3 along line BB (i.e., the position where the side outlet 33 is located). Figure 12 is an enlarged view of the right side (left side when viewed from the front) of the cross-sectional view in Figure 10.

[0041] The LED holding member 42 is a member that extends longitudinally along the left and right sides of the shower duct forming member 30. Here, with reference to the position of the LED holding member 42 when it is attached to the shower duct forming member 30, the longitudinal ends of the LED holding member 42 are referred to as the inner end 42a and the outer end 42b.

[0042] The LED substrate 41 is attached to the side of the LED holding member 42 that is closer to the inner end 42a (see Figure 6). As described above, with the LED substrate 41 attached to the LED holding member 42, the mounting surface of the LED 44 on the LED substrate 41 faces the front side (refrigerator compartment 11 side). The part of the LED holding member 42 that faces the LED 44 is called the LED-facing surface portion 42c (or reflective surface 42c). Most of the light emitted from the LED 44 is first irradiated onto the LED-facing surface portion 42c (see Figure 12).

[0043] The area around the surface portion 42c facing the LED is the arrangement space for the LED 44. In this embodiment, two groups of LEDs 44 are scattered at three locations (i.e., the top, center, and bottom) on a single LED substrate 41. Accordingly, the LED holding member 42 is provided with three arrangement spaces for the LEDs 44. The arrangement spaces for the LEDs 44 in the LED holding member 42 are provided with a convex curved surface shape 61 and a light diffusion portion 62.

[0044] The convex curved surface shape 61 has a curved shape in which the width in the vertical direction expands from the inner end 42a side where the LED 44 is located toward the outer end 42b side. This allows the light emitted from the LED 44 to be diffused vertically toward the side end of the shower duct forming member 30.

[0045] The light diffusion section 62 is located near the LED 44. The surface of the light diffusion section 62 is provided with numerous circular recesses or protrusions, which allow it to diffuse and reflect the light irradiated onto it.

[0046] The LED cover 43 is provided so as to cover the LED holding member 42 to which the LED substrate 41 is attached. In other words, the LED holding member 42 and the LED cover 43 form the space for the LED substrate 41.

[0047] Here, the LED cover 43 is referred to as the rear portion 43a and the side portion 43b, with reference to its position when attached to the shower duct forming member 30. The rear portion 43a is positioned approximately parallel to the rear portion 52a of the inner box 52 (see Figure 10, etc.). The side portion 43b is positioned approximately parallel to the side portion 30b of the shower duct forming member 30 (see Figure 10, etc.).

[0048] The LED cover 43 is made of a highly light-transmitting material, such as a colorless, transparent resin, and has the property of transmitting light. As a result, the light emitted from the LED 44 mainly passes through the LED cover 43 and is irradiated into the refrigerator compartment 11.

[0049] The side portion 43b of the LED cover 43 is processed to diffuse the light from the LED 44 over a wider area. Specifically, a light diffusion portion 71 is provided on the inner surface of the side portion 43b of the LED cover 43. The light diffusion portion 71 is formed by a number of circular recesses or protrusions. In this embodiment, the light diffusion portion 71 is provided at three locations on the side portion 43b to correspond to the placement positions of the LED 44.

[0050] The back portion 43a of the LED cover 43 is processed to more efficiently direct the light from the LED 44 towards the back portion 52a of the inner box 52. Specifically, a light guide portion 72 is provided on the inner surface of the back portion 43a of the LED cover 43. The light guide portion 72 is formed by a number of slit-shaped grooves extending in the vertical direction. In this embodiment, the light guide portions 72 are provided at three locations on the back portion 43a to correspond to the placement positions of the LEDs 44.

[0051] The following describes the path of light from the LED 44 when the refrigerator compartment 11 is illuminated by the rear light 40, with reference to Figure 12. In Figure 12, the path of light emitted from the LED 44 is indicated by arrows.

[0052] The light emitted from the LED 44 is directional in the vertical direction from the light-emitting surface. Therefore, as shown by the white arrows in Figure 12, the light emitted from the LED 44 is mainly directed toward the surface 42c of the LED holding member 42 that faces the LED. Since the LED holding member 42 has light-reflecting properties, much of the light directed toward the surface 42c is reflected and travels toward the back surface 43a of the LED cover 43.

[0053] The light that travels to the back portion 43a of the LED cover 43 is guided to the back portion 52a of the inner box 52, passing through the light guide portion 72 as shown by the solid arrow in Figure 12. The light then travels to the back portion 52a, where it is reflected and proceeds towards the inside of the refrigerator (refrigerated compartment 11).

[0054] A portion of the light reflected by the opposing surface 42c travels toward the side surface 43b of the LED cover 43. The light that travels toward the side surface 43b of the LED cover 43 passes through the light diffusion section 71 and travels toward the side of the refrigerator compartment 11, along the rear surface 52a of the inner box 52, as shown by the dashed arrow in Figure 12.

[0055] As described above, most of the light emitted from the LED 44 is first reflected by the surface 42c of the LED holding member 42 that faces the LED, and then passes through the LED cover 43 to irradiate the inside of the refrigerator (i.e., the refrigerator compartment 11). To improve the efficiency of light utilization, it is preferable that the surface 42c facing the LED has high reflectivity. This allows more of the light emitted from the LED 44 to be irradiated from the LED cover 43 into the inside of the refrigerator. It is also preferable that minute irregularities are formed on the surface 42c facing the LED. This scatters the light from the LED 44, blurring the light source image of the LED 44.

[0056] Furthermore, much of the light reflected by the opposing surface 42c is guided by the light guide 72 to the back surface 52a of the inner box 52, and is reflected by the back surface 52a, illuminating the inside of the storage compartment. In this way, by reflecting the light from the LED 44 twice, once by the opposing surface 42c and once by the back surface 52a of the inner box 52, even when using an LED 44 with relatively high directivity as a light source, the degree of directivity can be reduced compared to when the light emitted from the LED 44 is directly illuminating the inside of the storage compartment. Therefore, unevenness in brightness when illuminating the inside of the storage compartment with an LED can be reduced.

[0057] Furthermore, some of the light reflected by the opposing surface 42c passes through the side portion 43b of the LED cover 43 and is irradiated into the interior of the storage unit. Since a light diffusion portion 71 is provided on this side portion 43b, the degree of directionality of the light from the LED 44 can be reduced. Therefore, unevenness in brightness when illuminating the interior of the storage unit using LEDs can be reduced.

[0058] Furthermore, as shown in Figures 10 and 11, a heat insulating member 22 is placed between the shower duct cover 21, which is provided on the front side of the shower duct forming member 30, and the LED holding member 42. This makes it difficult for the heat emitted from the LED 44 to be transmitted to the inside of the refrigerator (refrigerator compartment 11). It also prevents the light emitted from the LED 44 from passing through the shower duct forming member 30 and leaking into the inside of the refrigerator.

[0059] Furthermore, as shown in Figure 11, a side air outlet 33 is provided on the back side of the LED substrate 41 having the LED 44. In other words, a passage for cold air sent from the shower duct 31 into the chamber is provided on the back side of the LED 44. This allows the heat-generating LED 44 to be cooled by the cold air.

[0060] (Summary of the first embodiment) As described above, the refrigerator 1 according to this embodiment comprises an inner box 52 that forms the inner wall of the refrigerator compartment 11, and a shower duct forming member 30 provided on the rear portion 52a of the inner box 52. The shower duct forming member 30 forms a cold air passage (i.e., a shower duct 31). An LED 44 is positioned on the rear side of the side surface of the shower duct forming member 30. Light emitted from the LED 44 is reflected by the rear portion 52a of the inner box 52 and irradiated into the storage space such as the refrigerator compartment 11.

[0061] With the above configuration, even when using LEDs with relatively high directivity as the light source, the degree of directivity can be reduced compared to directly illuminating the interior of the storage unit with light emitted from the LEDs. Therefore, unevenness in brightness when illuminating the interior of the storage unit with LEDs can be reduced.

[0062] Furthermore, in the refrigerator 1 according to this embodiment, a reflective member is provided on the back side of the shower duct cover 21, which is provided on the front side of the shower duct forming member 30, to reflect the light emitted from the LED 44 toward the inner box 52. Specifically, the surface 42c of the LED holding member 42 that faces the LED is a reflective surface that reflects the light emitted from the LED 44.

[0063] With this configuration, the optical axis of the light emitted from the LED 44 can be directed towards the LED holding member 42. As a result, direct light from the LED 44 does not reach the eyes of the user positioned in front of the refrigerator compartment 11, and only indirect light reaches them. Therefore, the feeling of glare caused by the light emitted from the LED 44 can be reduced.

[0064] Furthermore, the refrigerator 1 according to this embodiment is provided with an LED cover 43 that can transmit light while diffusing the light reflected by the LED holding member 42. As a result, the intensity of the light from the back light 40 is reduced, so that even though there is lighting on the back side of the refrigerator compartment 11, glare is suppressed and the efficiency of light utilization is increased. In addition, by reducing the intensity of the light from the back light 40, unevenness in brightness inside the refrigerator compartment 11 can be reduced, and a high-quality refrigerator 1 can be provided.

[0065] <Second Embodiment> Next, a second embodiment of the present invention will be described. In the first embodiment described above, a rear light 40 composed of a white reflective member (LED holding member 42) and a colorless, transparent diffuser member (LED cover 43) was used as an example. However, the colors of the reflective member and the diffuser member are not limited to these.

[0066] In the refrigerator 1 according to the second embodiment, the light-emitting color of the LED 44, the color of the reflective member (LED holding member 42), and the color of the diffuser member (LED cover 43) may be changed as appropriate. This makes it possible to change the color tone of the light irradiated into the interior from the rear light 40 according to the purpose.

[0067] Furthermore, in the refrigerator 1 according to this embodiment, the light-emitting color of the LED 44, which is the light source of the rear light 40, and the light-emitting color of the light source (e.g., LED, fluorescent lamp, etc.) of the ceiling light 58 may be different. For example, the light-emitting color of the LED 44 of the rear light 40 can be set to a warm color, and the light-emitting color of the light source of the ceiling light 58 can be set to white. By controlling the illumination methods of the rear light 40 and the ceiling light 58 respectively, the brightness, color tone, and atmosphere inside the refrigerator compartment 11 can be appropriately changed according to the purpose.

[0068] <Third Embodiment> Next, a third embodiment of the present invention will be described. In the first embodiment described above, a configuration in which the inside of the refrigerator compartment 11 is illuminated using two types of lighting devices (i.e., a ceiling light 58 and a rear light 40) was described as an example. However, the lighting inside the refrigerator compartment 11 may be of only one type.

[0069] In the refrigerator 1 according to the third embodiment, only a rear light 40 is provided as lighting inside the refrigerator compartment 11. A ceiling light 58 is not provided.

[0070] In such a configuration, it is preferable to use an LED with higher light intensity as the LED 44 that serves as the light source for the rear light 40.

[0071] The above configuration allows for a reduction in the number of components compared to a configuration using two types of lighting devices. Furthermore, it reduces the power consumption required for interior lighting.

[0072] (summary) A refrigerator according to one aspect of the present invention (for example, refrigerator 1) comprises an inner box (for example, inner box 52) that forms the inner wall of a storage space (for example, refrigerator compartment 11), a duct forming member (for example, shower duct forming member 30, shower duct cover 21) provided on the rear part (for example, rear part 52a) of the storage space and forming a cold air passage (for example, shower duct 31), and an LED (for example, LED 44) positioned on the rear side of the side surface of the duct forming member. Light emitted from the LED is reflected by the inner box and irradiated into the storage space.

[0073] In a refrigerator according to one aspect of the present invention described above (for example, refrigerator 1), a reflective member (for example, LED holding member 42) may be provided on the back side of a cover member (for example, shower duct cover 21) provided on the front side of the duct forming member (for example, shower duct forming member 30) to reflect light emitted from the LED (for example, LED 44) toward the inner box (for example, inner box 52).

[0074] In a refrigerator according to one aspect of the present invention described above (for example, refrigerator 1), an insulating material (for example, insulating member 22) may be placed between the cover member (for example, shower duct cover 21) and the reflective member (for example, LED holding member 42).

[0075] In a refrigerator according to one aspect of the present invention described above (for example, refrigerator 1), the reflective member (for example, LED holding member 42) may be provided with a convex curved shape (for example, convex curved shape 61) that diffuses the light emitted from the LED (for example, LED 44) in the vertical direction.
