Detailed Description

Embodiments are described based on the drawings. The following embodiments are examples, and the scope of the invention is not limited thereto. The following embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. The following embodiments and modifications thereof are included in the scope of the invention described in the claims and equivalents thereof.

In the following description, the door side for opening and closing the storage room is referred to as front, and the opposite side is referred to as rear. In addition, left and right refer to left and right as viewed by a user standing in front of the refrigerator.

First, the overall configuration of the refrigerator 10 will be explained. Fig. 1 shows a refrigerator 10 according to an embodiment. The casing 11 of the refrigerator 10 is formed by combining an outer box 12 forming an outer contour of the refrigerator 10 and an inner box 13 forming a storage chamber, and filling a heat insulating material 14 between the outer box 12 and the inner box 13.

The inside of the frame 11 is partitioned vertically by a heat insulating partition wall 15. The upper side of the heat insulating partition wall 15 is a refrigerating space. The refrigerating space is maintained at a temperature suitable for refrigerated preservation, i.e., a refrigerating temperature. Further, the lower side of the heat insulating partition wall 15 is a freezing space. The freezing space is maintained at a freezing temperature suitable for cryopreservation. The refrigerating space and the freezing space are respectively provided with a plurality of storage chambers for storing food. Each storage chamber has an opening at the front, and a user can take out and put in food from the opening.

A refrigerating chamber 20 and a vegetable chamber 22, which are storage chambers, are provided in this order from top to bottom in the refrigerating space. The temperature in the refrigerating chamber 20 is maintained within a range of refrigerating temperature, for example, 2 to 5 ℃, and the temperature in the vegetable chamber 22 is maintained within a range of refrigerating temperature, for example, 4 to 7 ℃. The refrigerating compartment 20 is provided with a plurality of placement shelves 24. A fresh air compartment 39, which is maintained at a particularly low temperature even in the lower refrigerating compartment 20, is formed below the lowermost placement shelf 24. In the vegetable compartment 22, a drawer type container 40 and an upper container 41 placed thereon are housed.

The front opening of the refrigerating compartment 20 is opened and closed by a pair of right and left French (split) refrigerating compartment doors 21. Although not shown, the operation panel 45 (see fig. 2) is provided on the refrigerating compartment door 21. Further, a door sensor 44 (see fig. 2) is provided to sense opening and closing of the refrigerating chamber door 21.

The front opening of vegetable room 22 is opened and closed by a drawer-type vegetable room door 23. The drawer-type container 40 is fixed to the surface of the vegetable compartment door 23 on the inside of the compartment. Therefore, when the user opens the vegetable compartment door 23, the drawer type container 40 and the upper side container 41 placed on the drawer type container 40 are integrally pulled out.

An ice making compartment and a small freezing compartment 26 are provided as storage compartments at an upper portion of the freezing space, and a freezing compartment 28 is provided as a storage compartment at a lower portion of the freezing space. The interior of ice making chamber and freezing chamber 28 is maintained at a temperature in the range of freezing temperature, for example, 20 ℃ to 18 ℃. The inside of small freezing room 26 is maintained at a temperature in the range of freezing temperature, for example, -18 to-16 ℃. Drawer type storage containers 18 and 19 are stored in small freezing chamber 26 and freezing chamber 28, respectively.

The front opening of small freezing chamber 26 is opened and closed by drawer-type storage chamber door 27. The storage container 18 is fixed to the surface of the storage chamber door 27 on the inner side of the case. The front opening of freezing chamber 28 is opened and closed by drawer-type freezing chamber door 29. The storage container 19 is fixed to the inner surface of the freezer door 29. The front opening of the ice making chamber is opened and closed by a drawer-type ice making chamber door (not shown).

A first cooler 30 for generating cool air and a first fan 32 for circulating the generated cool air are provided at the rear of the refrigerating space. The cold air generated by first cooler 30 is blown out from a plurality of blow-out openings 36 to the refrigerating space via duct 34 extending upward from first cooler 30. The cold air circulating in the refrigerating space is sucked from the suction port 38 toward the first cooler 30.

Further, a second cooler 31 for generating cold air and a second fan 33 for circulating the generated cold air are provided behind the freezing space. The cold air generated by second cooler 31 is blown out to the freezing space from blow-out port 35 formed in the rear surface of the freezing space, circulated in the freezing space, and then sucked into second cooler 31 from suction port 37 formed in the rear surface of the freezing space.

A machine chamber 16 is provided at the rear of the lower portion of the refrigerator 10. The machine room 16 houses a compressor 17, a condenser (not shown), and the like.

An interior lighting device 50 is provided on the ceiling 42 of the refrigerating compartment 20. Although not shown, an interior lighting device is also provided in the refrigerating compartment 20 at a location such as a rear surface (rear surface) 25. In addition, an interior lighting device is also provided in the storage room other than the refrigerating room 20.

The compressor 17, the condenser, the first cooler 30, the second cooler 31, and the like constitute a known refrigeration cycle apparatus. The refrigerant compressed by the compressor 17 alternately flows through the first cooler 30 and the second cooler 31, and when the refrigerant flows through the first cooler and the second cooler, cold air is generated in the respective coolers.

As shown in fig. 2, the refrigerator 10 is provided with a control unit 43. The control unit 43 is connected to various sensors such as a door sensor 44, various devices such as the interior lighting device 50, the compressor 17, the first fan 32, and the second fan 33, in addition to the operation panel 45. The control unit 43 controls various devices based on instructions from the operation panel 45 and detection signals from various sensors. The control part 43 lights the in-box illumination device 50 when the door sensor 44 senses that the refrigerating compartment door 21 is opened, and lights the in-box illumination device 50 when the door sensor 44 senses that the refrigerating compartment door 21 is closed.

Next, the in-box illumination device 50 will be explained. The in-box illumination device 50 is provided on the ceiling 42 which is one of the inner walls of the refrigerating compartment 20. As shown in fig. 3, the in-box illumination device 50 includes a housing portion 51 provided on the ceiling 42, a substrate 54 provided inside the housing portion 51, an LED55 connected to the substrate 54, and a globe 56 covering the housing portion 51.

As shown in fig. 3, the storage portion 51 is formed as a portion recessed from the inner surface of the refrigerating compartment 20, i.e., the surface of the ceiling 42. The housing 51 is formed of a recessed surface 52 and a side surface 53, the recessed surface 52 is located higher than the ceiling 42, and the side surface 53 extends from the recessed surface 52 to the opening of the housing 51 in the vertical direction. The recessed surface 52 may be regarded as a ceiling surface in the housing 51. The ceiling 42 and the recessed surface 52 are horizontal surfaces.

The concave surface 52 has a higher reflectance than the inner surface of the other portion of the refrigerating compartment 20 (the inner surface of the inner case 13). For example, the concave surface 52 is adhered with a metal foil, colored in a color close to white than the inner surface of the other portion of the refrigerating compartment 20, or finished to be smooth than the inner surface of the other portion of the refrigerating compartment 20, so that the reflectance is higher than the inner surface of the other portion of the refrigerating compartment 20.

The side surface 53 may have a higher reflectance as in the case of the depressed surface 52. The surface of the ceiling 42 of the refrigerating compartment 20 may have a higher reflectance as in the case of the recessed surface 52.

As shown in fig. 4, when the housing portion 51 is viewed from below, the side surface 53 includes: planar portions 53a and 53b extending in the left-right direction at two front and rear positions; a curved surface portion 53c connecting left and right end portions of the planar portion 53a and the planar portion 53 b; and a curved surface portion 53d connecting the left and right ends of the flat surface portion 53a and the flat surface portion 53b to each other. The curved surface portions 53c, 53d are semicircular when viewed from below.

A substrate 54 on which a circuit pattern is formed is vertically fixed to the front flat surface portion 53a by screws or the like, not shown. The substrate 54 is parallel to the flat surface portion 53 a. An LED55 as a light emitting member is provided on a rear surface of the substrate 54 (a surface on the center side of the housing portion 51). The number of the LEDs 55 provided on the substrate 54 is plural, and they are arranged in the left-right direction. The LED55 is connected to the control unit 43 via a circuit of the board 54, and is turned on and off under the control of the control unit 43.

The LED55 emits light in a direction toward the rear, i.e., toward the rear flat surface portion 53b of the housing 51. Here, the irradiation direction refers to the direction of the optical axis of the light emitted from the LED55, and is the traveling direction of the light. Light of the LED55 is vertically irradiated to the flat surface portion 53 b. In fig. 3 and 4, the irradiation direction of light from the LED55 is shown by a dotted arrow. As shown in fig. 3, the light of the LED55 is irradiated in parallel with the concave surface 52 of the housing 51.

As shown in fig. 3, a downward opening of the storage portion 51 is closed by a cover 56 serving as a cover. The globe 56 has a shape and a size fitted into the housing 51. The globe 56 is attached to the housing 51 by fitting the edge 57 thereof into the side surface 53 of the housing 51. By providing the globe 56, the housing portion 51, which is a space in which the LEDs 55 are provided, becomes a closed space.

The lamp housing 56 has a uniform thickness as a whole, and has a curved surface protruding downward from the lower surface thereof. The lamp housing 56 is transparent or translucent throughout. Therefore, the light of the LED55 is reflected and diffused in the sealed storage portion 51, and then passes through the lamp cover 56 to illuminate the inside of the refrigerating compartment 20.

Minute irregularities are formed on one of the upper and lower surfaces of the globe 56. Examples of the irregularities include irregularities formed by arranging linear ridges at predetermined intervals, and irregularities formed by regularly or irregularly distributing point-like protrusions. Further, the unevenness may be formed by surface processing such as rubbing processing or texturing processing.

In the in-box illumination device 50, when the LED55 emits light, the light travels rearward and is irradiated to the rear flat surface portion 53b of the housing portion 51, and is reflected by the rear flat surface portion 53b and travels forward. During this time, the light is diffused in a direction different from the optical axis of the light from the LED55, for example, upward and downward. The light diffused upward is reflected by the concave surface 52 of the housing 51 and travels downward. As a result of the light being reflected and diffused in the housing 51, the light is substantially uniformly transmitted through the entire globe 56.

In this way, since light is transmitted substantially uniformly through the entire globe 56, when the user views the in-box illumination device 50, the entire globe 56 can be seen to be uniformly bright. The light transmitted through the lamp housing 56 illuminates the placement shelf 24 and the like located below the in-box illumination device 50.

Next, the effects of the present embodiment will be explained. In the refrigerator 10 of the present embodiment, the flat surface portion 53b as a wall portion is provided at a position in the light irradiation direction of the LED55 as a light emitting member. Therefore, the light from the LED55 does not directly reach the user's eyes, and when the user views the interior illumination device 50, the location of only the LED55 does not appear bright. Then, the light of the LED55 is reflected by the flat surface portion 53b as a wall portion and diffused. Accordingly, when the user views the in-box illumination device 50, the user can see a wide range of the area to emit light uniformly, and the in-box illumination device 50 has good appearance.

In particular, since the LED55 is provided in the housing 51 and the flat surface portion 53b as a wall portion of the housing 51 is provided at a position in the light irradiation direction of the LED55, the light of the LED55 is reflected and diffused by the flat surface portion 53 b. Therefore, the entire storage portion 51 can be seen to emit light uniformly and to have good appearance.

Further, since the globe 56 covers the housing 51 in which the LEDs 55 are housed, and the light reflected and diffused inside the housing 51 uniformly transmits through the entire globe 56, the entire globe 56 is uniformly brightened, and the appearance of the in-box illumination device 50 is improved.

Further, since the irregularities are formed on the globe 56, even if the light from the LED55 is not sufficiently irradiated to a part of the globe 56, the irregularities diffuse the light, and the entire globe 56 is uniformly brightened.

Further, since the reflectance of the concave surface 52 of the housing 51 and the like is high, the globe 56 becomes brighter, and the inside of the case can be brightly illuminated.

Further, since the light of the LED55 is emitted rearward, there is no risk that the LED55 is visually observed by the user through the globe 56, and poor appearance due to the LED55 being visually observed can be avoided.

Next, a modified example will be explained.

< example 1 of variation

As shown in fig. 5, the housing 151 of the present modification is formed of a recessed surface (a portion surrounded by reference numerals 153a and 153b in fig. 5) located higher than the surface of the ceiling 42 and a side surface 153 extending from the recessed surface in the vertical direction to the opening of the housing 151, as in the above-described embodiment.

The side surface 153 includes a flat surface portion 153a extending in the left-right direction at the front end portion of the housing portion 151, and a curved surface portion 153b formed rearward from the flat surface portion 153 a. The curved surface portion 153b is a single curved surface connecting the right end portion and the left end portion of the planar portion 153 a.

The substrate 54 is provided in parallel with the planar portion 153a on the front planar portion 153 a. Further, an LED55 is provided on the rear surface of the substrate 54 (the surface on the center side of the housing 151). A downward opening of the storage 151 is closed by a transparent or translucent lampshade (not shown).

The LED55 emits light in the direction of the rear curved surface 153b in the housing 151. Therefore, the light emitted from the LED55 is reflected not only toward the front but also toward the entire housing 151 including the left and right directions by the curved surface 153 b. As a result, the light reaches the entire housing 151, and the user can see that the entire globe emits light uniformly when viewing the lighting device 50 in the box.

< modification 2 >

The wall portion directly irradiated with the light emitted from the LED55 serving as the light emitting member may be curved or inclined with respect to the irradiation direction. The modification 1 described above is one of such modifications, but another modification is shown in fig. 6 to 10. The shape of the housing portion shown in fig. 6 to 10 when viewed from below is not limited, but is, for example, the same shape as that shown in fig. 4.

In the housing 251 of the modification shown in fig. 6, as in the above-described embodiment, the front planar portion 53a and the rear planar portion 53b face each other, and the substrate 54 and the LED55 are provided on the front planar portion 53 a. In this modification, the upper recessed surface 52 and the rear flat surface portion 53b are connected by a curved surface portion 253 as a wall portion. The curved surface portion 253 is a curved surface having a shape that reflects downward the light of the LED55 that travels backward in parallel with the recessed surface 52. In this modification, part of the light traveling straight from the LED55 is irradiated to the curved surface portion 253 and reflected not only forward but also downward. Therefore, the globe 56 covering the housing 251 is brightened.

In addition, a portion obtained by combining the portion of the curved surface portion 253 and the portion of the flat surface portion 53b in fig. 6 may be a curved surface such as the curved surface portion 253 described above, without the rear flat surface portion 53 b.

In the housing portion 351 of the modification shown in fig. 7, an inclined flat portion 353 is provided instead of the curved portion 253 shown in fig. 6, and the inclined flat portion 353 is a wall portion inclined with respect to the light irradiation direction of the LED 55. The inclined plane portion 353 is inclined in a direction in which light from the LED55 that travels backward in parallel with the recessed surface 52 is reflected downward. In the modification of fig. 7, part of the light traveling straight from the LED55 is irradiated onto the inclined plane portion 353 and reflected not only forward but also downward, and therefore the globe 56 covering the housing portion 351 becomes brighter.

In the housing portion 451 according to the modification shown in fig. 8, the front flat surface portion 53a and the rear flat surface portion 53b face each other as in the case of fig. 3, but unlike the case of fig. 3, the entire recessed surface 452 is inclined with respect to the surface of the ceiling 42. The recessed surface 452 is inclined so as to be higher as it gets closer to the front flat surface portion 53 a. Although the light from the LED55 is weaker as it travels (i.e., as it is farther from the front flat surface portion 53a), the concave surface 452 is inclined as shown in fig. 8, so that the light is reflected by the concave surface 452 before being weakened, and the shade 56 is brightened. Part of the light of the LED55 is reflected by the rear flat surface portion 53b toward the front, and the vicinity of the LED55 in the globe 56 is brightened.

In the storage portion 551 according to the modification shown in fig. 9, the entire recessed surface 552 is inclined with respect to the surface of the ceiling 42. The recessed surface 552 is inclined to be higher as it gets closer to the front flat surface portion 53 a. In this modification, the rear flat surface portion (but a portion into which the globe 56 is fitted) is not present. In this modification, the light from the LED55 is reflected by the concave surface 552 before being attenuated, and the globe 56 is lightened.

In the storage portion 651 according to the modification shown in fig. 10, the entire recessed surface 652 is inclined with respect to the surface of the ceiling 42. The recessed surface 652 is inclined to be higher as it gets closer to the front flat surface portion 53 a. The recessed surface 652 extends to the interior 25 of the fresh food compartment 20 and is joined to the interior 25. That is, the storage portion 651 according to this modification extends to the rear surface 25 of the refrigerating compartment 20. Light from the LED55 is reflected by striking the recessed surface 652. Thus, a wide range of the upper and rear surfaces 25 in the box can be seen brightly. Although fig. 10 shows a mode without a cover, a cover covering the housing 651 from below may be provided.

< example 3 >

Fig. 11 to 13 show modifications of the lamp cover. The shape of the globe of fig. 11 to 13 when viewed from below is not limited, and is, for example, a shape fitting into the housing portion 51 of fig. 4.

A lamp cover 756 of the modification shown in fig. 11 includes a surface portion 756a forming a surface inside the case, and a fitting portion 756b as a portion fitted into the housing 51. The fitting portion 756b is formed upward from the edge of the fitting portion 756 b. Further, the surface portion 756a is planar. The boundary between the surface portion 756a and the fitting portion 756b becomes a corner portion 756 c. The fitting part 756b is fitted inside the side surface 53 of the housing 51 so that the lamp cover 756 is attached to the housing 51.

Since the shade 756 does not bulge downward like the shade 56 of the above embodiment, the storage space can be enlarged, and the user can easily take in and out the storage at the upper portion of the refrigerating compartment 20. Further, although there is a concern that the portion near the LED55 may be darkened without being directly irradiated with light from the LED55, if the corner 756c is formed in the portion near the LED55 as in the globe 756, the portion near the LED55 may not be darkened significantly.

As another modification, the shape of the globe may be different between the front portion and the rear portion.

For example, in the case 856 of the modification shown in fig. 12, a corner 856c is formed only at the front end. Thus, the corner 856c is formed in a portion close to the LED55, and the portion close to the LED55 does not become dark. Further, a portion of the globe 856 behind the corner 856c is uniformly brightened.

In each of the lamp covers shown above, the front portion (e.g., the portion corresponding to the portion below the LED 55) near the LED55 may be thinner than the other portions, thereby allowing light to easily pass therethrough. Thereby, a portion of the globe near the LED55 is also brightened, and the entire globe is uniformly brightened.

In this way, by making the shape (including the thickness in the shape) different between the front portion and the rear portion of the globe, the portion of the globe that is likely to be darkened is made inconspicuous, and the entire globe can be uniformly brightened.

As shown in fig. 13, a non-translucent paint 956a may be applied to a front portion of the globe 956 (e.g., a portion below the LED 55). This prevents the user from seeing even if the light emitted from the LED55 to the front portion of the globe 956 is weak.

In contrast to fig. 13, a light-transmitting paint may be applied to a rear portion of the globe 956 (e.g., a portion other than the paint 956a of fig. 13). This reduces the light transmittance of the coated portion, and therefore, even if the light from the LED55 applied to the front portion of the globe 956 is weak, the entire globe 956 becomes uniformly bright.

< example 4 >

The surface of the LED55 as the light-emitting member may be formed of a material having a high reflectance. For example, a discontinuous deposited metal film having translucency made of metal may be formed on the surface of the LED55, thereby increasing the reflectance of the surface of the LED 55. When the surface of the LED55 has a high reflectance, when light reflected by the wall portion such as the rear flat portion 53b in fig. 3 returns to the position of the LED55, the light is reflected again by the surface of the LED 55. Thereby, the in-box illumination device 50 becomes brighter.

The light emitting member is not limited to an LED, and may be a fluorescent lamp or the like.

< example 5 >

The place where the in-box illumination device of the above embodiment is installed is not limited to the ceiling 42, and may be the surface of the inside of the box of the refrigerating compartment door 21, the back surface 25 of the refrigerating compartment 20, or the like.

The storage room provided in the interior illumination device of the above embodiment is not limited to the refrigerating room 20, and may be a vegetable room 22, a freezing room 28, an ice-making room, and the like.
