Description
CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to and the benefit of Korean Patent Application No. 10-2022-0172409, filed on Dec. 12, 2022, the disclosure of which is incorporated herein by reference in its entirety.


TECHNICAL FIELD

The present disclosure relates to a refrigerator, and in particular, a refrigerator that comprises a lighting part radiating light around a handle part.


BACKGROUND

Refrigerators supply cold air, generated based on a heat exchange with refrigerants circulating in a cooling cycle, to a storage compartment, and keep various types of storage items fresh in the storage compartment for a long period of time.


Lighting is installed in a storage compartment, to allow a user to check storage items in the storage compartment as the user opens the door of the storage compartment.


However, since additional lighting is not provided outside a refrigerator, a user needs another light source in the case where the user uses the refrigerator in the night, and inconvenience is caused to the user.


In particular, a pocket-type handle drawn inside the door of the refrigerator is hardly recognized by the user from the outside, making it hard for the user to recognize the position of the handle part in the night.


Additionally, a sensor part can be disposed at the door of the refrigerator and senses an approach of the user.


The sensor part cannot sense an approach of the user in a blind spot based on the position and angle of the sensor part, making it difficult for the sensor part to play its role properly.


For example, the sensor part senses a space formed by the user making a specific motion, such as a space between the open legs of the user, and wrongly senses that the user does not approach, although the user approaches to the sensor part.


Further, even in the case where a companion pet rather than the user approaches to the sensor part, the sensor part is likely to operate wrongly.


SUMMARY

The objective of the present disclosure is to provide a refrigerator comprising a lighting part that radiates light around a handle part, such that a user can readily find the position of the handle part even in the night.


The objective of the present disclosure is to provide a refrigerator that can reduce a blind spot as a sensor part operates.


The objective of the present disclosure is to provide a refrigerator that can reduce a sensing error of a sensor part, caused by a specific behavior of a user, or an operational error of the sensor part, caused by an approach of a companion pet.


The objective of the present disclosure is to provide a refrigerator that can reduce a sense of difference felt by a user toward a handle part, caused by heat generated by a lighting part.


The objective of the present disclosure is to provide a refrigerator that can allow a user to readily find the position of a handle part of a lower door as well as the position of a handle part of an upper door, by using a lighting part disposed at the upper door.

In another aspect, the upper door may comprise a hinge part rotating around one side of the cabinet, the hinge part may be disposed further rearward than the upper handle part, and the hinge part and the lighting part may be disposed to overlap each other with respect to an extension line extending in a left-right direction of the upper door.


In another aspect, a sensor part may be disposed at a slant on the lower surface of the upper door, to face a central line with respect to a left-right direction of the cabinet.


In another aspect, the sensor part may be a proximity sensor sensing an approach of a user.


In another aspect, a sensing line extending from the sensor part to a sensible point of the sensor part may cross the central line.


In another aspect, a maximum sensible point of the sensor part may be on the central line.


In another aspect, the sensor part may be disposed horizontally with respect to an up-down direction of the cabinet.


In another aspect, the upper door may comprise a hinge part rotating around one side of the cabinet, and the sensor part may be disposed in a way that the sensor part is eccentric to the hinge part with respect to a left-right direction of the upper door.


In another aspect, the sensor part may protrude further downward than the lower surface of the upper door.

In the refrigerator of the present disclosure, the sensor part sensing an approach of a user is disposed on the lower surface of the upper door at a slant, toward the central line with respect to the left-right direction of the cabinet, such that one sensor part reduces a blind spot that cannot be sensed by the sensor part, with no need to install an additional sensor part respectively on the lower surface of the pair of upper doors.


In the refrigerator of the present disclosure, since the sensor part is disposed horizontally with respect to the up-down direction of the cabinet, the sensor part targets and senses an area near the upper ends of the legs of an ordinary user, thereby reducing a sensing error of the sensor part in a blind spot that is created in the case where the user opens the legs, or an operational error of the sensor part, caused by an approach of a companion pet.


In the refrigerator of the present disclosure, since the lighting part disposed at the rear of the handle part that is disposed on the lower surface of the pair of upper doors is inserted into and disposed in the protrusion part protruding downward, the handle part and the lighting part are spaced a predetermined distance apart from each other in the up-down direction as well as the front-rear direction, thereby reducing a sense of difference toward the handle part, which is felt by the user as the lighting part generates heat.


In the refrigerator of the present disclosure, since the rear surface of the lower handle part inclines rearward from the lower portion of the lower handle part to the upper portion thereof, a light radiation angle may be formed to radiate light of the lighting part disposed on the lower surface of the upper door to the inside of the lower handle part, thereby allowing the user to readily find the position of the handle part of the lower door as well as the position of the handle part of the upper door by using the lighting part disposed at the upper door.


Specific effects are described along with the above-described effects in the section of detailed description.

Hereafter, a refrigerator in several embodiments is described.


A refrigerator 1 of one embodiment, and main components constituting the refrigerator 1 are described with reference to FIGS. 1 to 12.


Unless described otherwise, an up-down direction, a left-right direction and a front-rear direction in the present disclosure are defined with respect to a direction where the user in front of the refrigerator 1 sees the refrigerator 1.


The exterior of the refrigerator 1 may be formed by a cabinet 2 comprising one or more storage compartments 3, 4, as a storage space of an item, therein, and a plurality of doors 10, 20, 30 opening and closing an open front surface of the cabinet 2.


The cabinet 2 may be shaped into a box the front surface of which is open, and may be divided into one or more storage spaces and comprise a refrigerator compartment and/or a freezer compartment.


The cabinet 2 may comprise an upper storage compartment 3 and a lower storage compartment 4 that are disposed respectively vertically.


For example, the upper storage compartment 3 may be a refrigerator compartment, and the lower storage compartment 4 may be a freezer compartment, but not limited.


A first upper door 10 and a second upper door 20 that are a pair of upper doors opening and closing the front surface of the upper storage compartment 3 may be disposed on the front surface of the cabinet 2, corresponding to the upper storage compartment 3.


The first upper door 10 and the second upper door 20 may be a rotating door and respectively rotate through a first hinge part 150 and a second hinge part 250 that rotates around one side and the other side of the cabinet 2 as a rotation axis.


A lower door 30 may be disposed on the front surface of the cabinet 2, corresponding to the lower storage compartment 4, and open and close the front surface of the lower storage comportment 4.


The lower door 30 may be a drawer-type door that is inserted and drawn by a rail in the font-rear direction, but not limited. The lower door 30 may be a rotating door.


Additionally, one lower door 30 is illustrated in the present disclosure, but the number of lower doors is not limited. A plurality of lower doors 30 may be provided to open and close the lower storage compartment 4 in a segmented manner.


A dispenser part 5 for taking out driving water and ice may be disposed on the front surface of the first upper door 10.


The first upper door 10 may comprise a first upper outer door 11 being disposed on the front surface 10a of the first upper door 10, a first upper door liner 13 being disposed on the rear surface 10c of the first upper door 10, and a first upper door cap deco 12 being disposed on the lower surface 10b of the first upper door 10.


At this time, a side frame may be disposed on a lateral surface of the first upper door 10, and a cap deco may be disposed on the upper surface of the first upper door 10, to form the exterior of the first upper door 10.


Hereafter, the lower surface 10b of the first upper door 10 as a first upper door cap deco 12 is described, for example.


A first upper handle part 110, a first lighting part 130, a sensor part 140, and a first hinge part 150 may sit at the first upper door cap deco 12.


According to the present disclosure, since the first upper door cap deco 12 finishes the lower area of the first upper door 10 and has a structure in which the first upper handle part 110, the first lighting part 130, the sensor part 140 and the first hinge part 150 can be mounted, the spatial availability of the first upper door 10 may improve.


Additionally, in the state where the first upper handle part 110, the first lighting part 130, the sensor part 140 and the first hinge part 150 sit at the first upper door cap deco 12, the first upper door cap deco 12 may be fastened to the first upper door liner 13 and the first upper outer door 11, improving efficiency in assembly processing.


A pocket-type first upper handle part 110 may be disposed on the lower surface 10b of the first upper door 10 in a way that the pocket-type first upper handle part 110 is drawn upward inside the first upper door 10.


The first upper handle part 110 may be disposed in a way that the first upper handle part 110 is eccentric to the other side of the first upper door 10, which is opposite to one side of the first upper door 10 at which the first hinge part 150 is disposed, out of both lateral surfaces of the first upper door 10.


The first hinge part 150 may be disposed further rearward than the first upper handle part 110, and the first hinge part 150 and the first lighting part 130 may be disposed to overlap each other, with respect to an extension line that extends in the left-right direction of the first upper door 10.


The first upper handle part 110 may be formed in a way that the first upper handle part 110 extends in the left-right direction to have a predetermined length.


The first upper handle part 110 may be disposed at the front of the lower surface 10b of the first upper door 10, such that the user puts a hand into the first upper handle part 110 and opens and closes the first upper door 10 readily and rapidly.


However, since the first upper handle part 110 is drawn upward inside the first upper door 10, not to be seen by the user from the front surface of the refrigerator 1, the first lighting part 130 may be disposed at the rear of the first upper handle part 110 such that the user may find the position of the first upper handle part 110 easily.


The first lighting part 130 is turned on, to easily guide the position of the first upper handle part 110 for the user, as the user approaches to the refrigerator 1.


The first lighting part 130 may extend in the left-right direction to have a predetermined length, and a left-right length of the first lighting part 130 may be greater than a left-right length of the first upper handle part 110.


Since the first upper handle part 110 and the first lighting part 130 may be disposed to overlap each other with respect to the front-rear direction of the refrigerator 1, in the case where the first lighting part 130 is turned on, the first light part 130 may guide the position of the first upper handle part 110 more accurately for the user.


The first lighting part 130 may be formed at a first protrusion part 120 formed on the lower surface 10b of the first upper door 10.


Specifically, the first protrusion part 120 may protrude further downward than the first upper handle part 110 to have a predetermined height.


The first protrusion part 120 may be disposed further rearward than the first upper handle part 110.


A first insertion groove 121 may be formed at the first protrusion part 120 and drawn upward inside the first protrusion part 120, and the first lighting part 130 may be inserted into and fixed to the first insertion groove 121.


Accordingly, the first insertion groove 121 may extend in the left-right direction to have a predetermined length, and may have a left-right length greater than a left-right length of the first upper handle part 110.


Further, the first upper handle part 110 and the first insertion groove 121 may be disposed to overlap each other with respect to the front-rear direction of the refrigerator 1.


Since the first lighting part 130 is inserted into and fixed to the first insertion groove 121, the first lighting part 130 may radiate light toward the lower portion of the first upper door 10.


Thus, even in the case where the first lighting part 130 is turned on, light is not directly radiated to the user, and the possibility that the user is affected by glare may be reduced.


In the case where the first lighting part 130 is closely adjacent to the first upper handle part 110, heat that is generated as the first lighting part 130 is turned on is transferred to the first upper handle part 110, such that the user feels a sense of difference due to a difference in temperatures of the first upper handle part 110, in the case where the user puts a hand into the first upper handle part 110 and contacts the first upper handle part 110.


In the present disclosure, the first lighting part 130 is disposed further rearward than the first upper handle part 110, and inserted and disposed in the first protrusion part 120 protruding downward, such that the first upper handle part 110 and the first lighting part 130 may be spaced a certain distance apart from each other in the up-down direction as well as the front-rear direction.


Thus, even in the case where the first lighting part 130 is turned on, the transfer of heat from lighting to the first upper handle part 110 may decrease significantly, to reduce a sense of difference that may be felt by the user as the user puts a hand into the first upper handle part 110 and contacts the first upper handle part 110.


In the present disclosure, the first protrusion part 120 may provide a space into which the user puts a hand, at the first upper handle part 110.


The first upper handle part 110 is shaped into a pocket that is drawn from the lower surface 10b of the first upper door 10 to the inside of the first upper door 10 upward, and needs an enough space in which the user puts a hand.


Accordingly, a sufficient space that at least corresponds to the height of the first protrusion part 120 may be provided for the user to put a hand in to the first upper handle part 110, thereby enhancing user convenience.


In the present disclosure, the first lighting part 130 inserted and disposed in the first protrusion part 120 may be disposed further rearward and downward than the first upper handle part 110, the first lighting part 130 may not be interfered with by a hand of the user and radiate light constantly and reliably, even when the user puts a hand into the first upper handle part 110.


The first lighting part 130 may comprise a first lighting member cover 132 that protects a first lighting member 131, and the first lighting member 131 radiating light and finishes the lower surface of the first insertion groove 121.


For example, the first lighting member 131 may be provided in a way that a plurality of LED light-emitting elements is disposed on a substrate extending in one direction.


At this time, each of the LED light-emitting elements may radiate light in one color, but not be limited. Each of the LED light-emitting elements may radiate light to embody different colors such as red, green, blue (RGB).


The first lighting member cover 132 may extend in one direction in a way that the first lighting member cover 132 surrounds the front surface and the lateral surfaces of the first lighting member 131.


The first lighting member cover 132 may be hook-fastened to the first insertion groove 121 in a way that the first lighting member cover 132 is readily detachable from the first insertion groove 121 formed on the lower surface 10b of the first upper door 10.


The first lighting member cover 132 may comprise a light guide plate, or be formed to provide a function as a light guide plate, helping light radiated from the first lighting member 131 to be released far away and uniformly.


For example, the first lighting member cover 132 may be made of a translucent material, to prevent the creation of a spot where light concentrates, or further comprise a diffusion agent.


A first hinge insertion groove 151 may be formed at one side of the lower surface 10b of the first upper door 10, and the first hinge part 150 may be fixed to the first hinge insertion groove 151 and allow the first upper door 10 to swivel.


The first hinge insertion groove 151 may be formed at the first protrusion part 120.


A sensor insertion groove 122 that is drawn upward may be formed at the first protrusion part 120, and the sensor part 140 may be inserted into and fixed to the sensor insertion groove 122.


For example, since the sensor insertion groove 122 is eccentric to the first hinge part 150 with respect to the left-right direction of the first upper door 10, the sensor part 140 may also be eccentric to the first hinge part 150 with respect to the left-right direction of the first upper door 10.


The sensor part 140 may comprise a sensor 141 sensing an approach of the user, and a sensor cover 142 protecting the sensor 141 and finishing the lower surface of the sensor insertion groove 122.


The sensor 141 may be a proximity sensor that senses the user approaching to an area within a sensible point, based on a set sensible point.


The sensor 141 may sense an approach and an escape of the user within the set sensible point, and communicate with the controller of the refrigerator 1 to turn on and off the first lighting part 130 of the first upper door 10 and the second lighting part 230 of the second upper door 20.


In the present disclosure, the handle part 110, 210, and the lighting part 130, 230 disposed at the rear of the handle part 110, 210 may be disposed respectively on the lower surface of the pair of upper doors 10, 20, and the sensor part 140 may sense an approach of the user, enabling the user to easily find the position of the handle part 110, 210 without an additional external light source even in the night.


Thus, user convenience may improve, and thanks to high-end exterior design, aesthetic qualities may be provided.


The sensor cover 142 may comprise another area into which an additional component such as a printed circuit board for removing noise is inserted and fixed, in addition to an area into which the sensor 141 is inserted and fixed.


At this time, a partial area of the sensor cover 142 protecting the sensor 141 may protrude further downward than the first protrusion part 120.


Since the sensor 141 is accommodated in a partial area of the sensor cover 142, protruding further downward than the first protrusion part 120, the sensor 141 may be disposed to protrude further downward than the first protrusion part 120.


Referring to FIGS. 8 and 10, since the sensor 141 is disposed further downward than the lower surface 10b of the first upper door 10, the sensing line SL of the sensor 141 may face toward the front surface of the refrigerator 1 without being interfered with by the lower surface 10b of the first upper door 10.


Accordingly, when viewing the refrigerator 1 from the front surface of the refrigerator 1, the user may recognize the sensor 141 and a portion of the sensor cover 142 protecting the sensor 142.


The sensor part 140, as described above, may be disposed horizontally with respect to the up-down direction of the cabinet 2, and the sensing line (SL) may extend in parallel.


Thus, the extension line of the sensing line (SL) may sense near the upper ends of the legs of an ordinary user 6.


For example, in the case where the extension line of the sensing line (SL) senses near the lower ends of the legs of an ordinary adult user 6, a vacant space formed by the user making a specific motion, such as a vacant space between the open legs of the user, may be a blind spot of the sensor part 140, although the user is positioned within the sensible point.


At this time, the sensor part 140 may wrongly sense that the user escapes from the sensible point.


Additionally, in the case where the extension line of the sensing line (SL) senses near the lower ends of the legs of an ordinary adult user 6, the sensor part 140 may operate unnecessarily in the case where a companion pet passes.


In the present disclosure, the sensor part 140 may be disposed horizontally with respect to the up-down direction of the cabinet 2, to target and sense near the upper ends of the legs of an ordinary user.


Thus, a sensing error of the sensor part 140, caused by a blind spot that is created when the user opens the legs, or an operational error of the sensor part 140 caused by an approach of a companion pet may be reduced.


Referring to FIG. 7, the sensor part 140 disposed on the lower surface 10b of the first upper door 10 may be disposed at a slant, such that the sensor 141 faces a central line (CL) with respect to the left-right direction of the cabinet 2.


Accordingly, the sensing line (SL) extending from the sensor part 140 to the sensible point (SP) of the sensor part 140 may cross the central line (CL).


At this time, the sensible point (SP) may extend further by passing through the point at which the sensing line (SL) crosses the central line (CL), but may be placed on the central line (CL).


Accordingly, the sensible point (SP) placed on the central line (CL) of the sensor part 140 may be a maximum sensible point of the sensor part 140.


For example, the sensible point (SP) may be spaced from the front surfaces of the first upper door 10 and the second upper door 20 by a distance of about 400 mm-800 mm.


Preferably, the sensible point (SP) may be spaced from the front surfaces of the first upper door 10 and the second upper door 20 by a distance of about 600 mm, for example.


The above-described distance between the sensible point (SP) and the front surfaces of the first upper door 10 and the second upper door 20 may correspond to a distance at which the user 6 reaches the first upper door 10 and the second upper door 20 when an ordinary user 6's arm reaches out.


In the present disclosure, since the sensor part 140 sensing an approach of the user is disposed at a slant on the lower surface of the upper door 10, 20, toward the central line (CL), with respect to the left-right direction of the cabinet 2, one sensor part 140 may control the turn on and off of the first lighting part 130 of the first upper door 10 and the second lighting part 230 of the second upper door 20, without disposing an additional sensor part 140 respectively on the lower surface of the pair of upper doors 10, 20.


Further, since the sensible point (SP) of the sensor part 140 crosses the central line (CL) with respect to the left-right direction of the cabinet 2, one sensor part 140 may reduce a blind spot at a time when the sensor part 140 operates.


Referring to FIG. 6, a first penetration hole 121h communicating with the first insertion groove 121, and a second penetration hole 122h communicating with the sensor insertion groove 122 may be formed inside of the upper portion of the first upper door cap deco 12.


A first lighting member harness 133 may connect to the first lighting member 131 through the first penetration hole 121h, and a sensor harness 143 may connect to the sensor 141 through the second penetration hole 122h, such that a variety of signals and a power source are supplied respectively to the first lighting member 131 and the sensor 141.


Further, a second upper handle part 210, a second lighting part 230 and a second hinge part 250 may sit on the lower surface 20b of the second upper door 20.


The second upper handle part 210, the second lighting part 230, and the second hinge part 250 have a substantially similar structure and a substantially similar function to those of the first upper handle part 110, the first lighting part 130 and the first hinge part 150 described above. Accordingly, description in relation to this is omitted.


Further, the second upper handle part 210, the second lighting part 230 and the second hinge part 250 may have a position and a shape that are approximately symmetrical to the position and the shape of the first upper handle part 110, the first lighting part 130 and the first hinge part 150, with respect to the central line (CL) of the refrigerator 1.


The second upper handle part 210 drawn upward inside the second upper door 20, and the second lighting part 230 disposed at the rear of the second upper handle part 210 may be disposed on the lower surface 20b of the second upper door 20.


A second protrusion part 220 protruding further downward than the second upper handle part 210 that comprises an second insertion groove drawn upward inside the second upper door 20 may be disposed on the lower surface 20b of the second upper door 20, and the second lighting part 230 may be inserted into the second insertion groove.


In an example, the second upper door 20 may comprise a second upper door body part 21 at which the second hinge part 250 rotating around the other side of the cabinet 2 is disposed, and a second upper sub door 22 which is disposed on the front surface of the second upper door body part 21 in a way that the second upper sub door 22 swivels around one side of the second upper door body part 21.


Accordingly, the second upper door 20 may swivel in the state where the second upper door body part 21 and the second upper sub door 22 are coupled, and the second upper sub door 22 may only swivel in the state where the second upper door body part 21 is fixed to the cabinet 2.


At this time, the second protrusion part 220, and the second lighting part 230 inserted into the second protrusion part 220 may be disposed at the second upper door body part 21, and the second upper handle part 210 may be formed at the second upper sub door 22.


Since the second lighting part 230 and the second upper handle part 210 are individually disposed at the second upper door body part 21 and the second upper sub door 22 as described above, the second lighting part 230 and the second upper handle part 210 may be disposed not to be affected by a coupling or a decoupling of the second upper door body part 21 and the second upper sub door 22.


In the drawing of the present disclosure, the sensor part 140 is disposed on the lower surface 10b of the first upper door 10, for example, but not limited. Also, the sensor part 140 may be disposed on the lower surface 20b of the second upper door 20 in a way that the sensor part 140 is eccentric to the second hinge part 250 with respect to the left-right direction of the second upper door 20.


In the case where the sensor part 140 is disposed on the lower surface 20b of the second upper door 20 as described above, the sensor part 140 does not need to be disposed on the lower surface 10b of the first upper door 10, and the sensor part 140 on the lower surface 20b of the second upper door 20 may be disposed at a slant toward the central line CL with respect to the left-right direction of the cabinet 2.



FIG. 9 is a lateral cross-sectional view showing a first upper door 10 at which a first lighting part 130 is disposed and a lower door 30.


The first lighting member 131 of the first lighting part 130 may be disposed to face the lower door 30, and a lower handle part 310 drawn downward inside the lower door 30 may be disposed on the upper surface 30d of the lower door 30.


The upper surface 30d of the lower door 30 may be embodied as a cap deco that finishes the upper surfaces of the front surface 30a of the lower door 30 and the rear surface 30c of the lower door 30, but not limited. The upper surface 30d of the lower door 30 may be embodied as a coupling form having a variety of structures.


The first upper handle part 110 and the lower handle part 310 may be disposed to overlap at least partially, with respect to the up-down direction of the refrigerator 1.


Specifically, the rear surface 310c of the lower handle part 310 may be disposed further rearward than the rear surface 110c of the first upper handle part 110.


At this time, the rear surface 310c of the lower handle part 310 is formed to have an inclination surface that inclines rearward from the lower portion of the lower handle part 310 toward the upper portion thereof.


For example, the uppermost end of the rear surface 310c of the lower handle part 310 may be disposed further rearward than the front surface 120a of the first protrusion part 120.


Additionally, the uppermost end of the rear surface 310c of the lower handle part 310 may be disposed further rearward than the front surface 121a of the first insertion groove 121 into which the first lighting part 130 is inserted, but not limited.


For example, the uppermost end of the rear surface 310c of the lower handle part 310 may be disposed at the same position as the front surface 121a of the first insertion groove 121 in the front-rear direction, or disposed between the front surface 120a of the first protrusion part 120 and the front surface 121a of the first insertion groove 121.


In the present disclosure, since the rear surface 310c of the lower handle part 310 inclines rearward from the lower portion of the lower handle part 310 to the upper portion thereof, a light radiation angle may be formed such that light of the light part 130, 230 on the lower surface of the upper door 10, 20 is radiated toward the inside of the lower handle part 310.


Thus, the user may easily find the position of the handle part 110, 210 of the lower door 30 as well as the position of the handle part 110, 210 of the upper door 10, 20, by using the lighting part 130, 230 disposed at the upper door 10, 20.


Further, in the present disclosure, since the rear surface 310c of the lower handle part 310 inclines rearward from the lower portion of the rear surface 310c of the lower handle part 310 to the upper portion thereof, the viewing angle of the user may be ensured such that the user recognizes the rear surface 310c of the lower handle part 310 on which light is radiated.


A position relationship between the first upper handle part 110 and the lower handle part 310 is described above. A position relationship between the second upper handle part 210 and the lower handle part 310 may be the same as that between the first upper handle part 110 and the lower handle part 310. Accordingly, detailed description of the position relationship between the second upper handle part 210 and the lower handle part 310 may be omitted.


Referring to FIGS. 11 and 12, a chamfer part 14 may be formed at one side of the lower portion of the rear surface 10c of the first upper door 10.


For example, the chamfer part 14 may be beveled in a way that the edge portion of one side of the lower portion of the first upper door liner 13 forming the rear surface 10c of the first upper door 10 inclines partially.


Accordingly, the area of the rear surface 10c of the first upper door 10 corresponding to the chamfer part 14 may be formed to protrude rearward.


Since the first upper handle part 110 is drawn in the upward direction of the first upper door 10, a thermal insulation foam liquid injected into the first upper door 10 may decrease by the drawn area.


In particular, in the case where a distance between the first upper handle part 110 drawn inward and the first upper door liner 13 forming the rear surface 10c of the first upper door 10 is too short, a thermal insulation effect may deteriorate significantly at the first upper handle part 110.


In the present disclosure, the chamfer part 14 is formed in a way that a minimum distance d1 between the first upper handle part 110 and the first upper door line 13 where the chamfer part 14 is formed is greater than a minimum distance d2 between the first upper outer door 11 and the first upper door liner 13, preventing deterioration in a thermal insulation effect in the area of the first upper handle part 110.



FIG. 13 is a view showing the operation logics of a sensor part, based on various behavior scenarios of a user, and FIG. 14 is a view showing a flow chart of the operations of a sensor part, based on various behavior scenarios of a user.


As the sensor part 140 senses an approach of the user (S20), the first lighting part 130 and the second lighting part 230 may be turned on in first predetermined brightness (S21).


At this time, the first predetermined brightness may be approximate 50% of the maximum brightness of the first lighting part 130 and the second lighting part 230, but not limited.


In the case where one or more of the first upper door 10 and the second upper door 20 is opened, the first lighting part 130 and the second lighting part 230 may be turned off (S22, S24, S26).


Additionally, in the case where the first upper door 10 and the second upper door 20 are closed, in the state where the sensor part 140 senses an approach of the user, the first lighting part 130 and the second lighting part 230 may be turned on in the first predetermined brightness (S23, S25, S27).


Further, in the case where the sensor part 140 senses an approach of the user, the first lighting part 130 and the second lighting part 230 may be turned on in the first predetermined brightness (S21).


In the case where the lower door 30 is opened, the first lighting part 130 and the second lighting part 230 may be turned on in second predetermined brightness that is greater than the first predetermined brightness (S28).


At this time, the second predetermined brightness may be approximately 100% of the maximum brightness of the first lighting part 130 and the second lighting part 230, but not limited.


In the case where the lower door 30 is opened as described above, the brightness of the first lighting part 130 and the second lighting part 230 are adjusted to maximum brightness, such that the first lighting part 130 and the second lighting part 230 serve as an indoor light of the lower storage compartment 4, thereby enhancing user convenience further.


In the case where the lower door 30 is closed in the state where the sensor part 140 senses an approach of the user, the first lighting part 130 and the second lighting part 230 may be turned on in the first predetermined brightness (S29).


Additionally, in the case where the sensor part 140 senses an approach of the user, the first lighting part 130 and the second lighting part 230 are turned on in the first predetermined brightness, and in the case where the user escapes from a sensible point of the sensor part 140 (S30), the first lighting part 130 and the second lighting part 230 may dim off slowly for a certain period of time (S31).


At this time, the first lighting part 130 and the second lighting part 230 dim off after a certain period of time, e.g., approximately three seconds, but not limited.


Further, since the first lighting part 130 and the second lighting part 230 are controlled to dim off slowly as the user escapes from the sensible point, the aesthetic qualities of the refrigerator 1 may improve in terms of design.


The embodiments are described above with reference to a number of illustrative embodiments thereof.
