Description

Refrigerator with a refrigerator body
Technical Field
The present invention relates to a refrigerator having an LED lighting in a room.
Background
The refrigerator has a storage room provided with illumination for brightening the inside of the refrigerator. For example, japanese patent application laid-open No. 2009-47360 discloses a refrigerator in which an in-box lighting device 80 is provided on a top plate of a refrigerating compartment 2.
In this refrigerator, a cooling plate 70 is mounted on the front side inner wall of the refrigerating chamber 2. The metal surface of the cooling plate 70 is mirror finished, and the cooling plate 70 reflects light emitted from the in-box lighting device 80.
Disclosure of Invention
The invention aims to solve the technical problems
In recent years, LEDs have been increasingly used as light sources for lighting devices in a refrigerator from the viewpoint of energy saving and the like. In general, light emitted from an LED has higher directivity than light from a fluorescent lamp or the like. Therefore, when a plurality of LEDs are arranged on the inner wall of the storage chamber, the optical paths from the LEDs are clearly visually checked. Further, since the LED is a point light source composed of a small light emitting element, there is a tendency that a difference in light emission intensity between the light emitting portion and the surrounding becomes large.
In this way, if the LED is used in the illumination in the interior of the refrigerator, the brightness is liable to be uneven according to the position of the storage chamber. Further, a specific area emits light strongly according to the arrangement position of the LEDs, and thus a user who opens the refrigerator door is also dazzled.
In one aspect of the present invention, an object is to provide a refrigerator capable of reducing uneven brightness when an inside of the refrigerator is illuminated by an LED.
Technical scheme for solving technical problems
A refrigerator according to an aspect of the present invention includes: an inner case forming an inner wall of the storage space; a duct forming member provided on a rear surface portion in the storage space and forming a cold air duct; and an LED disposed on a rear side of the side surface of the duct forming member. In this refrigerator, the light emitted from the LED is reflected by the inner case and irradiated into the storage space.
Advantageous effects
According to one aspect of the present invention, a refrigerator is provided that can reduce uneven brightness when an inside of the refrigerator is illuminated with LEDs.

The storage space formed by the heat insulating box 50 is divided into a plurality of storage compartments by a plurality of partitions extending in the horizontal direction. For example, the storage space of the refrigerator 1 is divided into a refrigerating chamber 11, a vegetable chamber, an ice making chamber, a second freezing chamber, and a freezing chamber in this order from the upper stage.
The refrigerating chamber 11 is provided with a split refrigerating chamber door (not shown) divided in left and right. The vegetable room is provided with a drawer-type vegetable room door 12a. A drawer type freezing chamber door 13a is provided in the freezing chamber. The ice making compartment is provided with a drawer type ice making compartment door 14a. A drawer type freezing chamber door 15a is provided in the second freezing chamber.
As described above, the refrigerator 1 according to the present embodiment is divided into a plurality of storage chambers, and the refrigerating chamber 11, the vegetable chamber 12, and the like are provided. However, the arrangement position of each storage space is not limited thereto. The arrangement of the doors in each storage space is not limited to the above configuration.
In the present embodiment, the face provided with the door is referred to as a front face or a front surface of the refrigerator. The front surface is used as a reference, and each surface of the refrigerator 1 is set as an upper surface, a side surface, a back surface, and a bottom surface based on a position existing when the refrigerator 1 is installed in a normal state. In addition, in a state where the refrigerator 1 is placed on the installation surface, the direction of the refrigerator 1 in the up-down direction is referred to as the up-down direction of the refrigerator 1. In addition, in a state where the refrigerator 1 is placed on the installation surface, the front-rear direction when the refrigerator 1 is viewed from the front is referred to as the front-rear direction of the refrigerator 1. The side located on the left side when viewed from the front side of the refrigerator 1 is referred to as the left side of the refrigerator 1 or the like, and the side located on the right side when viewed from the front side of the refrigerator 1 is referred to as the right side of the refrigerator 1 or the like.
Next, the structure of the refrigerating chamber 11 will be described. A shower forming member 30 is provided on the rear surface of the refrigerator compartment 11. The shower pipe forming member 30 is formed with a shower pipe 31 (see fig. 3, etc.) as a passage of cool air. The shower pipe 31 communicates with a cooling chamber in which a cooler is disposed, and sends cool air cooled by the cooler to the refrigerating chamber 11. The shower forming member 30 is provided with a plurality of air outlets (for example, a front air outlet 32, a side air outlet 33, and the like) for blowing cool air into the refrigerator compartment 11.
A lighting for lighting the inside of the refrigerator is provided in the refrigerating compartment 11. In the present embodiment, two kinds of illumination, that is, the dome lamp 58 and the back lamp 40 are provided. The dome lamp 58 is disposed on the upper surface of the inner wall of the refrigerating chamber 11. The dome lamp 58 is constituted by, for example, one or more LEDs. In other examples, dome lamp 58 may be formed of other lighting fixtures such as fluorescent lamps.
The back lamp 40 is provided to the shower pipe forming member 30. The back light 40 has a plurality of LEDs 44 as a light source. The plurality of LEDs 44 are arranged on the rear side (rear surface portion 52a side) of the side surface of the shower forming member 30. The detailed configuration of the back light 40 will be described later.
One or more storage cases 55 are provided below the inside of the refrigerator compartment 11.
(for shower pipe formation Member)
Next, a more detailed constitution of the shower pipe forming part 30 will be described.
Fig. 2 shows an external appearance of the shower pipe forming member 30. Fig. 3 shows a structure of the back surface side (side where the shower pipe 31 is provided) of the shower pipe forming member 30. Fig. 4 shows a configuration of the side surface side (side where the back surface lamp 40 is provided) of the shower pipe forming member 30. Fig. 5 shows the state of the components of the shower pipe forming member 30 in an exploded state. Fig. 6 shows a state in which the LED cover 43 is detached from the shower pipe forming member 30.
The shower forming member 30 is disposed along a rear surface portion 52a of the inner box 52 forming the rear surface side inner wall of the refrigerator compartment 11 (see fig. 4).
In the front surface portion 30a of the shower pipe forming member 30, a plurality of front surface air outlets 32 are arranged in a vertical direction. The front air outlet 32 communicates with the shower pipe 31, and blows out cool air passing through the shower pipe 31 to the refrigerator compartment 11.
In the side surface portion 30b of the shower pipe forming member 30, a plurality of side surface outlets 33 are arranged in the vertical direction. In the present embodiment, two side air outlets 33 are provided in the left side surface portion 30b as viewed from the front, and two side air outlets 33 are provided in the right side surface portion 30b as viewed from the front. The side air outlet 33 communicates with the shower pipe 31, and blows out cool air passing through the shower pipe 31 to the refrigerator compartment 11.
A back lamp 40 including an LED44 is provided on the rear side (back surface 52a side) of the side surface 30b of the shower forming member 30.
The shower forming member 30 mainly includes a shower cover 21, a heat insulating member 22, a grill member 23, a back surface lamp 40, and the like (see fig. 5).
The shower cover 21 forms the outer shape of the front surface side of the shower forming member 30. Here, the front surface side means a side located inside the case of the refrigerator compartment 11. That is, the shower cover 21 forms the front surface portion 30a and the side surface portion 30b of the shower forming member 30.
The heat insulating member 22 is made of a material having high heat insulating properties, such as foamed styrene. The heat insulating member 22 is disposed on the rear side (rear surface portion 52a side) of the shower cover 21. A concave groove extending in the up-down direction is formed on the back surface side of the heat insulating member 22. The groove is formed into a shower pipe 31 (see fig. 3). In the heat insulating member 22, holes or grooves communicating with the shower pipe 31 are formed at positions corresponding to the front side outlets 32 and the side outlets 33.
According to the above configuration, the heat insulating member 22 is positioned between the shower pipe 31 and the refrigerator compartment 11, and the heat insulating property between the shower pipe 31 and the refrigerator compartment 11 can be improved.
The grill member 23 is attached so as to cover an upper side outlet among the plurality of front outlets 32 provided in the shower cover 21. By attaching the grill member 23, the direction of the wind blown into the refrigerator compartment 11 from the front air outlet 32 can be restricted to a predetermined direction.
The back lamps 40 are provided along the side surface portions 30b of the left and right sides of the shower pipe forming member 30, respectively. Each back surface lamp 40 mainly includes an LED substrate 41, an LED holding member (reflecting member) 42, an LED cover (diffusing member) 43, and the like.
The LED substrate 41 has an elongated plate shape extending in the up-down direction. On one surface of the LED substrate 41, a plurality of LEDs 44 are arranged with a predetermined interval. In the present embodiment, two LEDs 44 are disposed at three positions (i.e., above, in the middle, and below) on one LED substrate 41. That is, 6 LEDs 44 are provided in the left back light 40 when viewed from the front, and 6 LEDs 44 are provided in the right back light 40 when viewed from the front.
The LED44 is a light source of the back light 40. Each LED44 has a light emitting diode element, and is designed to emit light at a predetermined wavelength. The emission color of the LED44 can be changed appropriately.
The LED holding member 42 holds the LED substrate 41. Fig. 6 shows a state in which the LED board 41 is mounted on the LED holding members 42 on the left and right sides. In a state where the LED board 41 is mounted on the LED holding member 42, the mounting surface of the LED44 of the LED board 41 faces the front side (the refrigerator 11 side).
The LED holding member 42 is formed of, for example, a resin material having light shielding properties and light reflecting properties. As a result, as will be described later, the light emitted from the LED44 can be reflected by the LED holding member 42 and directed toward the rear surface 52a side of the inner case 52. Thus, the LED holding member 42 is also referred to as a reflecting member. For example, the LED holding member 42 is formed of a white resin material.
The LED cover 43 is attached so as to cover the LED board 41 attached to the LED holding member 42. The LED cover 43 is formed of, for example, a resin material having light transmittance and light diffusion characteristics. As a result, as described later, light emitted from the LED44 can be diffused and irradiated to the outside of the LED cover 43 (i.e., the refrigerator compartment 11 side). Thus, the LED cover 43 is also called a diffusion member. For example, the LED cover 43 is formed of a colorless transparent resin material.
(for back lamps)
Next, a more detailed configuration of the back light 40 will be described.
Fig. 7 shows an appearance of the LED holding member 42. Fig. 7 shows a structure of the LED holding member 42 on the mounting side of the LED board 41. Fig. 8 and 9 show the appearance of the LED cover 43. Fig. 8 shows a structure of the inside of the LED cover 43 (the side on which the LED board 41 is located). Fig. 9 shows a structure of the outside (side facing the refrigerator compartment 11) of the LED cover 43.
Fig. 10, 11 and 12 show a cross-sectional structure of the inner box 52 and the shower pipe forming member 30. Fig. 10 is a cross-sectional view at the A-A line portion (i.e., where the LEDs 44 are arranged) of the shower pipe forming part 30 shown in fig. 3. Fig. 11 is a sectional view of the shower pipe forming member 30 shown in fig. 3 at a line B-B portion (i.e., a position where the side blow-out port 33 is arranged). Fig. 12 is a view showing a part of the right side (left side as viewed from the front) in the cross-sectional view of fig. 10 in an enlarged manner.
The LED holding member 42 is a member extending in the longitudinal direction along the side surfaces of the left and right sides of the shower forming member 30. Here, the longitudinal ends of the LED holding member 42 are referred to as an inner end 42a and an outer end 42b, based on the position of the LED holding member 42 in the state of being attached to the shower forming member 30.
The LED board 41 is mounted on a side close to the inner end 42a of the LED holding member 42 (see fig. 6). As described above, in a state in which the LED substrate 41 is mounted on the LED holding member 42, the mounting surface of the LED44 of the LED substrate 41 faces the front side (the refrigerator 11 side). In the LED holding member 42, a portion facing the LED44 is referred to as a facing surface 42c (or a reflecting surface 42 c) facing the LED. Most of the light emitted from the LED44 is first irradiated to the facing surface 42c facing the LED (see fig. 12).
The periphery of the facing surface 42c facing the LEDs serves as a disposition space for the LEDs 44. In the present embodiment, each group of two LEDs 44 is distributed at three places (i.e., above, in the middle, and below) on one LED substrate 41. Accordingly, three placement spaces for the LEDs 44 are provided in the LED holding member 42. A convex curved surface shape 61 and a light diffusion portion 62 are provided in the arrangement space of the LEDs 44 in the LED holding member 42.
The convex curved surface shape 61 has a curved surface shape such that the width in the up-down direction expands from the inner end 42a side toward the outer end 42b side where the LEDs 44 are arranged. This makes it possible to diffuse the light emitted from the LEDs 44 in the vertical direction toward the side end of the shower forming member 30.
The light diffusion portion 62 is provided in the vicinity of the LED44. A plurality of circular recesses or protrusions are provided on the surface of the light diffusion portion 62, so that light irradiated to the light diffusion portion 62 can be diffused and reflected.
The LED cover 43 is provided so as to cover the LED holding member 42 on which the LED board 41 is mounted. That is, the LED holding member 42 and the LED cover 43 form an arrangement space for the LED substrate 41.
Here, the respective face portions of the LED cover 43 are referred to as a back face portion 43a and a side face portion 43b, based on the position of the LED cover 43 in a state of being attached to the shower forming member 30. The back surface 43a is disposed in a positional relationship substantially parallel to the back surface 52a of the inner case 52 (see fig. 10, etc.). The side surface portion 43b is disposed in a positional relationship substantially parallel to the side surface portion 30b of the shower forming member 30 (see fig. 10, etc.).
The LED cover 43 is formed of a material having high light transmittance such as a colorless transparent resin material, for example, and has a light transmittance property. Thus, the light emitted from the LED44 is mainly irradiated to the refrigerator compartment 11 through the LED cover 43.
The side surface portion 43b of the LED cover 43 is subjected to a process for diffusing the light of the LED44 in a wider range. That is, the light diffusion portion 71 is provided on the inner surface of the side surface portion 43b of the LED cover 43. The light diffusion portion 71 is formed of a plurality of circular recesses or protrusions. In the present embodiment, the light diffusion portions 71 are provided at three portions of the side surface portion 43b so as to correspond to the arrangement positions of the LEDs 44.
The rear surface portion 43a of the LED cover 43 is subjected to processing for more efficiently emitting the light of the LED44 toward the rear surface portion 52a of the inner case 52. That is, the light guide 72 is provided on the inner surface of the back surface portion 43a of the LED cover 43. The light guide portion 72 is formed of a plurality of slit-shaped grooves extending in the up-down direction. In the present embodiment, the light guide portions 72 are provided at three positions of the back surface portion 43a so as to correspond to the arrangement positions of the LEDs 44.
The following describes a path of light from the LED44 when the refrigerator compartment 11 is illuminated by the back light 40, with reference to fig. 12. In fig. 12, the traveling path of the light emitted from the LED44 is indicated by an arrow.
Light from the LED44 has directivity in a vertical direction from the light emitting surface. Therefore, the light emitted from the LED44 is mainly irradiated toward the facing surface 42c of the LED holding member 42, which faces the LED, as indicated by the white arrow in fig. 12. Since the LED holding member 42 has a light reflection characteristic, most of the light irradiated to the facing surface 42c is reflected and travels toward the rear surface 43a of the LED cover 43.
The light entering the rear surface portion 43a of the LED cover 43 is guided to the rear surface portion 52a of the inner case 52 by the light guide portion 72 as indicated by the solid arrow in fig. 12. Then, the light guided to the back surface 52a is reflected by the back surface 52a and travels toward the inside of the box (the refrigerator compartment 11).
A part of the light reflected by the facing surface 42c travels toward the side surface 43b of the LED cover 43. As indicated by the broken-line arrows in fig. 12, the light entering the side surface portion 43b of the LED cover 43 travels laterally of the refrigerator compartment 11 along the rear surface portion 52a of the inner case 52 by the light diffusion portion 71.
As described above, most of the light emitted from the LED44 is first reflected by the LED holding member 42 and the LED facing surface 42c, and then irradiated into the box (i.e., the refrigerator compartment 11) through the LED cover 43. In order to improve the light use efficiency, the facing surface 42c facing the LED preferably has a high reflection characteristic. This allows more light emitted from the LED44 to be emitted from the LED cover 43 into the box. Further, minute irregularities are preferably formed on the facing surface 42c facing the LED. This causes light from the LED44 to scatter, thereby blurring the light source image of the LED44.
In addition, most of the light reflected by the facing surface 42c is guided to the rear surface 52a of the inner case 52 by the light guide 72, reflected by the rear surface 52a, and irradiated into the inside of the case. In this way, by reflecting the light from the LED44 twice on the facing surface 42c and the back surface 52a of the inner case 52, even when the LED44 having relatively high directivity is used as a light source, the degree of directivity can be reduced as compared with the case where the light emitted from the LED44 is directly irradiated into the case. Therefore, the variation in brightness in the case of illuminating the inside of the box with the LED can be reduced.
In addition, a part of the light reflected by the facing surface 42c is irradiated into the case through the side surface 43b of the LED cover 43. The side surface portion 43b is provided with a light diffusion portion 71, whereby the degree of directivity of light of the LED44 can be reduced. Therefore, the luminance unevenness in the case of illuminating the inside of the box with the LED can be reduced.
As shown in fig. 10 and 11, the heat insulating member 22 is disposed between the shower cover 21 and the LED holding member 42 provided on the front surface side of the shower forming member 30. This makes it difficult for the heat emitted from the LED44 to be transmitted to the inside of the cabinet (refrigerator 11). Further, the light emitted from the LED44 can be suppressed from leaking to the inside of the box through the shower pipe forming member 30.
As shown in fig. 11, a side surface outlet 33 is provided on the back surface side of the LED substrate 41 having the LEDs 44. That is, a passage for cool air sent from the shower duct 31 into the box is provided on the back surface side of the LED44. Thereby, the LED44 having heat generating property can be cooled by the cool air.
(summary of the first embodiment)
As described above, the refrigerator 1 of the present embodiment includes the inner case 52 forming the inner wall of the refrigerating chamber 11, and the shower forming member 30 provided on the rear surface portion 52a of the inner case 52. The shower pipe forming part 30 forms a cold air path (i.e., a shower pipe 31). An LED44 is disposed on the rear side of the side surface of the shower pipe forming member 30. The light emitted from the LED44 is reflected by the rear surface 52a of the inner case 52 and irradiates the storage space such as the refrigerator 11.
According to the above configuration, even when an LED having relatively high directivity is used as a light source, the degree of directivity can be reduced as compared with a case where light emitted from the LED is directly irradiated into the box. Therefore, the luminance unevenness in the case of illuminating the inside of the box with the LED can be reduced.
In the refrigerator 1 of the present embodiment, a reflecting member that reflects light emitted from the LED44 toward the inner case 52 is provided on the back surface side of the shower cover 21 provided on the front surface side of the shower forming member 30. Specifically, the facing surface 42c of the LED holding member 42 facing the LED serves as a reflecting surface for reflecting the light emitted from the LED44.
According to this configuration, since the optical axis of the light emitted from the LED44 can be directed toward the LED holding member 42, the direct light from the LED44 cannot reach the eyes of the user positioned on the front surface of the refrigerator compartment 11, and only the indirect light can reach. Therefore, the glare caused by the light emitted from the LED44 can be reduced.
In the refrigerator 1 of the present embodiment, an LED cover 43 is provided so as to diffuse and transmit light reflected by the LED holding member 42. This reduces the intensity of light from the back light 40, and therefore, the back side of the refrigerator compartment 11 can be illuminated, glare can be suppressed, and the light utilization efficiency can be improved. In addition, by reducing the intensity of light of the back light 40, the luminance unevenness in the refrigerator compartment 11 can be reduced, and the refrigerator 1 of high quality can be provided.
< second embodiment >
Next, a second embodiment of the present invention will be described. In the first embodiment, the back light 40 including the white reflecting member (LED holding member 42) and the colorless and transparent diffusing member (LED cover 43) is exemplified. However, the colors of the reflecting member and the diffusing member are not limited thereto.
In the refrigerator 1 of the second embodiment, the emission color of the LED44, the color of the reflecting member (LED holding member 42), and the color of the diffusing member (LED cover 43) may be appropriately changed. This allows the color tone of the light emitted from the back lamp 40 into the box to be changed according to the purpose.
In the refrigerator 1 according to the present embodiment, the emission color of the LED44 as the light source of the back light 40 may be different from the emission color of the light source (e.g., LED, fluorescent lamp, etc.) of the dome lamp 58. For example, the emission color of the LED44 of the back light 40 may be a warm color, and the emission color of the light source of the dome lamp 58 may be white. Further, by controlling the irradiation methods of the back light 40 and the dome light 58, the brightness, color tone, atmosphere, and the like in the refrigerator compartment 11 can be appropriately changed according to the purpose.
< third embodiment >
Next, a third embodiment of the present invention will be described. In the first embodiment, the description has been given taking an example of a configuration in which two types of illumination devices (i.e., the dome lamp 58 and the back lamp 40) are used to illuminate the interior of the refrigerator compartment 11. However, the illumination in the refrigerating chamber 11 may be one type.
In the refrigerator 1 of the third embodiment, only the back light 40 is provided as the illumination in the refrigerating chamber 11. The dome lamp 58 is not provided.
In the case of such a configuration, it is preferable to use an LED having a higher emission intensity as the LED44 serving as the light source of the back light 40.
According to the above configuration, the number of components can be reduced as compared with a configuration using 2 kinds of lighting devices. In addition, the power consumed for the illumination in the box can be reduced.
