Description

refrigerator

[0001] The present disclosure relates to a refrigerator.

[0002] A refrigerator is a home appliance that keeps food fresh by having a main body with a storage compartment, a cooling air supply device that supplies cooling air to the storage compartment, and a door that opens and closes the storage compartment.

[0003] Typically, storage rooms are designed with an open front for food entry and exit, and the open front is closed by a door. When the door is opened, cold air from inside the storage room escapes to the outside, and warm air from outside the storage room enters, potentially raising the temperature inside the storage room.

[0004] The temperature of a storage room must be maintained within a certain range to keep food fresh. If the temperature of the storage room rises, problems may arise in keeping food fresh, and additional energy may be consumed to lower the temperature of the storage room to normal.

[0005] Meanwhile, a French Door Refrigerator (hereinafter, FDR refrigerator) may include a rotating bar that is rotatably connected to the left door or the right door to prevent cold air from leaking through the gap between the left door and the right door.

[0006] One aspect of the present disclosure provides a refrigerator capable of reducing the operating rate of a heater of a rotating bar by applying a material having low thermal conductivity to the rotating bar.

Specifically, the plurality of storage rooms (21, 22, 23) can be divided into a first storage room (21), which is an upper storage room, and a second storage room (22) and a third storage room (23), which are lower storage rooms, by horizontal partitions, and the lower storage room can be divided into a second storage room (22) and a third storage room (23) by vertical partitions.

[0080] The first storage compartment (21) can be used as a refrigerator. The second storage compartment (22) and the third storage compartment (23) can be used as freezers. Although the second storage compartment (22) and the second storage compartment (23) can be used as freezers, the second storage compartment (22) can also be used as a freezer and the third storage compartment (23) can also be used as a refrigerator, or the second storage compartment (22) can be used as a freezer and the third storage compartment (23) can be used as both a freezer and a refrigerator. However, the division of use of the multiple storage compartments (21, 22, 23) is only one example and is not limited thereto.

[0081] The cold air supply device can generate cold air by using a cooling cycle of compressing, condensing, expanding, and evaporating a refrigerant, and supply the generated cold air to a plurality of storage chambers (21, 22, 23).

[0082] The plurality of storage compartments (21, 22, 23) can be opened and closed by a plurality of doors (31, 32, 33, 34). The plurality of doors (31, 32, 33, 34) can include a first door (31) and a second door (32) for opening and closing the upper storage compartment (20), and a pair of third doors (33) and a fourth door (34) for opening and closing the lower storage compartment (20). As an example, the first door (31) and the second door (32) can open and close the first storage compartment (21), the third door (33) can open and close the second storage compartment (22), and the fourth door (34) can open and close the third storage compartment (23).

[0083] Hereinafter, for the sake of convenience of explanation, only one first door (31) will be described, and the description of the remaining second doors will be omitted. However, the second door (32), whose description has been omitted, may have approximately the same configuration as the first door (31) described below, except that it is provided in a mirror-symmetrical manner. Furthermore, the second door (32) may also have the same configuration as the first door (31), and a detailed description thereof may be omitted.

[0084] The first storage compartment (21) can be opened and closed by a first door (31) that is rotatably connected to the main body (10). The first door (31) can include a door shelf (35) for storing food. The first door (31) can include shelf supports (36) provided on both sides of the door shelf (35) to support the door shelf (35).

[0086] When the first door (31) and the second door (32) are closed, a gap may be formed between the first door (31) and the second door (32). The gap formed between the first door (31) and the second door (32) may cause cold air inside the refrigerator (1) to leak out, thereby reducing thermal efficiency.

[0087] To solve this problem, a refrigerator (1) according to one embodiment may include a rotating bar (100) coupled to at least one of a first door (31) and a second door (32). The rotating bar (100) may cover a gap created between the first door (31) and the second door (32). For convenience of explanation, the rotating bar (100) will be described below based on the case where it is coupled to the first door (31).

[0088] The rotating bar (100) is arranged as shown in FIG. 2 when the first door (31) is open, and can rotate to cover the gap between the first door (31) and the second door (32) when the first door (31) is closed.

[0089] FIG. 3 is an exploded perspective view showing a first door (31) of a refrigerator (1) according to one embodiment and a rotating bar (100) coupled to the first door (31).

[0090] Referring to FIG. 3, the rotating bar (100) can be coupled or separated from the first door (31). The rotating bar (100) includes a cam device (200) coupled with the first door (31) and hinge members (110, 120), and may include a rotating bar body (300) forming the exterior of the rotating bar (100). The cam device (200) and the hinge members (110, 120) can be coupled and rotated so that a portion thereof is fixed to the first door (31). In the drawing, a case in which the cam device (200) and the hinge members (110, 120) are included is illustrated, but only the cam device (200) may be included, and the number of hinge members (110, 120) may be different from this. In addition, the position of the cam device (200) and the arrangement of the cam device (200) and the hinge member (110, 120) are only shown as examples in the drawing and can be arranged in various ways.

[0091] A first door (31) connecting portion may be provided on the upper portion of the first door (31) to be connected to the main body (10) and to allow the first door (31) to rotate. Although not shown, a connecting portion may also be provided on the lower portion of the first door (31) for connection to the main body (10).

[0092] The rotating bar (100) may be formed in a long bar shape in a vertical direction. The rotating bar body (300) may include a plurality of grooves for coupling the cam device (200) and the hinge members (110, 120). The cam device (200) and the hinge members (110, 120) may be coupled to the plurality of grooves.

[0093] Figures 4 and 5 are partial cross-sectional views of a refrigerator (1) according to one embodiment. Specifically, Figure 4 is an enlarged cross-sectional view of a portion where a first door (31) and a second door (32) face each other when the doors (31, 32) are closed, and Figure 5 is an enlarged cross-sectional view of a portion where a first door (31) and a second door (32) face each other when the first door (31) is open or is opened.

[0094] Referring to FIGS. 4 and 5, the plurality of doors (31, 32, 33, 34) may include a first door (31) and a second door (32). The first door (31) may include a first door gasket (31a) and a first gasket magnet (31b) provided inside the first door gasket (31a), and the second door (32) may include a second door gasket (32a) and a second gasket magnet (32b) provided inside the second door gasket (32a). The rotating bar (100) may include a rotating bar magnet (310) that magnetically interacts with the first door gasket (31a) magnet and the second gasket magnet (32b).

[0095] The first door gasket (31a) and the second door gasket (32a) are in close contact with the main body (10) and the rotating bar (100) to prevent cold air inside the first storage chamber (21) from leaking out to the outside.

[0096] The first gasket magnet (31b) and the second gasket magnet (32b) may be arranged so that their magnetic poles are identical with respect to the rotating bar (100). That is, the first gasket magnet (31b) and the second gasket magnet (32b) may be arranged so that the same magnetic poles face the main body (10). Among the rotating bar magnets (310), the portions corresponding to the first gasket magnet (31b) and the second gasket magnet (32b) may have magnetic poles opposite to the magnetic poles of the first gasket magnet (31b) and the second gasket magnet (32b). That is, the rotating bar magnet (310) can strengthen the adhesion between the rotating bar (100) and the first door (31) and between the rotating bar (100) and the second door (32) through the force of attraction with the first gasket magnet (31b) and the second gasket magnet (32b).

[0097] In order to exert an attractive force between the rotating bar magnet (310) and the first gasket magnet (31b) and between the rotating bar magnet (310) and the second gasket magnet (32b), the rotating bar magnet (310) may be a three-pole magnet. For example, if the portion of the first gasket magnet (31b) and the second gasket magnet (32b) facing the main body (10) is the N pole, the rotating bar magnet (310) may be a three-pole magnet arranged in the order of the S pole, the N pole, and the S pole.

[0098] The cam device (200) may include a hinge projection (210) that can be coupled with the first door (31), a fixed cam (220) connected to the hinge projection (210), a rotating cam (230) that is provided to be rotatable with respect to the fixed cam (220), and an elastic member (250) that is provided to elastically contact the fixed cam (220) and the rotating cam (230).

[0099] The fixed cam (220) is connected to the hinge protrusion (210) and can be fixed without rotating relative to the first door (31). The fixed cam (220) can be formed in an approximately cylindrical shape. The rotating cam (230) can rotate relative to the fixed cam (220).

[0100] The elastic member (250) can transmit elastic force to the rotary cam (230) by having one end of the elastic member (250) fixed to a part of the cam device (200) and the other end of the elastic member (250) contacting the rotary cam (230). The rotary cam (230) can convert the linear motion of the rotary cam (230) into the rotary motion of the rotary cam (230) by interacting with the fixed cam (220) through the elastic force transmitted from the elastic member (250). More specifically, the elastic member (250) can be configured to elastically contact the fixed cam (220) and the rotary cam (230) so that the linear motion of the rotary cam (230) is converted into the rotary motion of the rotary cam (230) due to the contact between the fixed cam (220) and the rotary cam (230). The rotational force formed by the interaction between the fixed cam (220) and the rotational cam (230) can be transmitted to the rotational bar body (300) to rotate the rotational bar (100). That is, the rotational force formed by the rotational movement of the rotational cam (230) can be transmitted to the rotational bar body (300) to rotate the rotational bar (100).

[0101] The rotating bar (100) may include an insulating material filled inside the rotating bar body (300) and a heating material (320) that prevents condensation caused by a temperature difference between the inside and outside of the refrigerator (1).

[0102] From the rear of the main body (10) toward the front of the main body (10), the insulating member, the rotating bar magnet (310), the heating member (320), the first gasket magnet (31b) and the second gasket magnet (32b) can be arranged in that order.

[0103] The angle between the rotating bar body (300, see FIG. 4) when the first door (31) is closed and the rotating bar body (300, see FIG. 5) when the first door (31) is opened may be approximately vertical. That is, when the first door (31) is opened, the rotating bar body (300) rotates counterclockwise with respect to the drawing, and when the first door (31) is closed, the rotating bar body (300) rotates clockwise so as to be positioned in the positions shown in FIGS. 4 and 5.

[0104] FIG. 6 is a perspective view of a rotating bar (100) of a refrigerator (1) according to one embodiment, and FIGS. 7 and 8 are exploded perspective views of a rotating bar (100) of a refrigerator (1) according to one embodiment.

[0105] Referring to FIG. 6, only the hinge at the top of the rotating bar is a cam device (200), and the other hinge members (110, 120) are not provided with cam devices (200), but this is only an example, and all hinge members (110, 120) may be cam devices (200).

[0106] The cam device (200) and hinge member (110, 120) can be attached to the first door (31) and detached from the first door (31) by means of a hook or the like.

[0107] Referring to FIGS. 7 and 8, the cam device (200) may include a rotating bar front body (330) partially exposed to the outside of the refrigerator (1) when the first door (31) is closed, a rotating bar rear body (340) facing the main body (10), a heating member (320), a rotating bar magnet (310), a cam device (200), and hinge members (110, 120). In a direction from the front to the rear of the refrigerator (1), the rotating bar front body (330), the heating member (320), the rotating bar magnet (310), and the rotating bar rear body may be arranged in this order. The cam device (200) and the hinge members (110, 120) may be coupled between the rotating bar front body (330) and the rotating bar rear body (340). Some of the hinge members (110, 120) may serve to supply power to the heating member (320) of the rotating bar (100).

[0108] The front body (330) of the rotating bar may include a plastic material in the portion exposed to the exterior of the refrigerator (1) when the first door (31) is closed. By including a plastic material with relatively low thermal conductivity, a decrease in thermal efficiency can be prevented. However, the use of a plastic material is not mandatory; including a material with sufficiently low thermal conductivity is sufficient.

[0109] In the drawing, the front body of the rotating bar (330) and the rear body of the rotating bar (340) are shown to be connected by screws, but the connection method is not limited to this, and it is sufficient to use a method that can stably connect the rotating bar body (300), the cam device (200), and the hinge member (110, 120).

[0110] FIG. 9 is a perspective view of a cam device (200) of a rotating bar (100) of a refrigerator (1) according to one embodiment, and FIG. 10 is an exploded perspective view of a cam device (200) of a rotating bar (100) of a refrigerator (1) according to one embodiment.

[0111] Referring to FIGS. 9 and 10, the cam device (200) may include a hinge protrusion (210) coupled to the first door (31), a fixed cam (220) connected to the hinge protrusion (210), a rotation cam (230) connected to the fixed cam (220), a rotation cam housing (240) covering a portion of the fixed cam (220) and the rotation cam (230) and an elastic member (250), a connecting rib (260) protruding from the outer surface of the rotation cam housing (240), and a cam coupling body (270) that fixes the rotation cam housing (240) and the fixed cam (220). As illustrated in FIGS. 9 and 10, the fixed cam (220) and the elastic member (250) may be centered on the rotation axis of the rotation bar (100), and the rotation cam (230) may rotate about the rotation axis of the rotation bar (100).

[0112] The fixed cam (220) may include a fixed cam body (221) connected to a hinge protrusion (210), and a fixed cam protrusion (222) protruding from an end of the fixed cam body (221). The fixed cam protrusion (222) may form a fixed cam mountain (2221) that is positioned farther away from the fixed cam body (221), and a fixed cam valley (2222) that is positioned closer to the fixed cam body (221). That is, the fixed cam mountain (2221) and the fixed cam valley (2222) may be positioned along the rotational direction of the cam device (200) with respect to the rotational axis of the rotation bar (100). The fixed cam protrusion (222) may form a shape in which the fixed cam mountain (2221) and the fixed cam valley (2222) are repeated, thereby allowing the fixed cam (220) to function as a cam.

[0113] The fixed cam (220) may include a rotating shaft (223) formed to protrude from the fixed cam body (221). The rotating shaft (223) may serve to prevent the fixed cam (220), the rotating cam (230), the elastic member (250), and the rotating cam housing (240) from departing from their original positions with respect to the rotational axis of the rotating bar (100). In the present disclosure, the rotating shaft (223) is illustrated as being included in the fixed cam (220), but the rotating shaft (223) may be formed in the rotating cam (230) or may be included in the cam device (200) as a separate member.

[0114] The rotary cam (230) may include a rotary cam body (231) forming an outer appearance, and a rotary cam protrusion (232) formed along the inner surface of the rotary cam body (231) along the circumferential direction of the cam device (200). The rotary cam protrusion (232) may form a rotary cam mountain (2321) and a rotary cam valley (2322), similar to the fixed cam (220).

[0115] The rotary cam (230) can be arranged at a first position (P1) where the rotary cam mount (2321) and the fixed cam valley (2222) correspond to each other when the first door (31) is closed. The rotary cam (230) can be rotated to a second position (P2) where the rotary cam mount (2321) is arranged at another fixed cam valley (2222) adjacent to the fixed cam valley (2222) when the first door (31) is closed when the first door (31) is opened. The rotary cam (230) can also be arranged at a critical position (C) where the rotary cam mount (2321) and the fixed cam valley (2221) correspond to each other between the first position (P1) and the second position (P2) and where the elastic force of the elastic member (250) is maximized.

[0116] The rotary cam (230) may include a guide protrusion (233) protruding from the outer surface of the rotary cam body (231). The guide protrusion (233) may transmit the rotary force of the rotary cam (230) to the rotary bar body (300) through the rotary cam housing (240).

[0117] The elastic member (250) may be a coil spring. However, it is not necessarily limited thereto, and it is sufficient for the elastic member (250) to be able to provide elastic force to the rotary cam (230) so that the rotary cam (230) can rotate smoothly between the first position (P1) and the second position (P2).

[0118] The rotating cam housing (240) may be formed in a hollow cylindrical shape. The rotating cam housing (240) may cover a portion of the fixed cam (220), the rotating cam (230), and the elastic member (250). The rotating cam housing (240) may include a guide groove (243) that is concavely formed to correspond to the guide protrusion (233) in order to transmit the rotational force of the rotating cam (230).

[0119] The connecting rib (260) can transmit the rotational force formed by the interaction of the fixed cam (220) and the rotating cam (230) to the rotating bar body (300). That is, the rotational force of the rotating cam (230) formed by using the elastic force of the elastic member (250) based on the fixed cam (220) can be transmitted to the rotating bar body (300) through the connecting rib (260) formed integrally with the rotating cam housing (240).

[0120] The connecting rib (260) may include a screw hole formed to be fixed to the rotating bar body (300). However, the method of coupling between the connecting rib (260) and the rotating bar body (300) is not limited thereto, and various methods such as a protrusion and groove coupling method may be applied.

[0121] The cam coupling body (270) can couple the fixed cam (220) and the rotating cam housing (240) to prevent the components inside the rotating cam housing (240) from being disassembled to the outside due to the elastic force of the elastic member (250). Specifically, the cam coupling body (270) can support a part of the fixed cam body (221) and a part of the rotating cam (230) housing and be coupled to the rotating cam housing (240) through a separate member. However, since this is only an example of arranging the components of the cam device (200) so as not to be disassembled, the present disclosure is not limited thereto, and the components of the cam device (200) can be coupled in various coupling methods.

[0122] FIGS. 11 to 13 are cross-sectional views of a cam device (200) of a rotary bar (100) of a refrigerator (1) according to one embodiment. Specifically, FIG. 11 is a drawing showing a first position (P1) state of a rotary cam (230), FIG. 12 is a drawing showing a critical position (C) state of a rotary cam (230), and FIG. 13 is a drawing showing a second position (P2) state of a rotary cam (230).

[0123] The rotary cam housing (240) may include a shaft fixing projection (241) capable of accommodating the rotary shaft (223). The shaft fixing projection (241) may position the rotary shaft (223) approximately in the middle of the rotary cam housing (240) to allow the fixed cam (220) and the rotary cam (230) to interact smoothly.

[0124] The connecting rib (260) can rotate about a rotation axis between a first position (P1) and a second position (P2) and can rotate the rotation bar body (300). When the rotation cam (230) moves a predetermined distance from the critical position (C) toward the first position (P1), it can move to the first position (P1) by elastic force, and when the rotation cam (230) moves a predetermined distance from the critical position (C) toward the second position (P2), it can move to the second position (P2) by elastic force.

[0125] The fixed cam protrusion (222) may include a first anti-friction groove (2223) formed on an inclined surface between the fixed cam mountain (2221) and the fixed cam valley (2222). The first anti-friction groove (2223) may reduce the contact area between the fixed cam protrusion (222) and the rotating cam protrusion (232), thereby facilitating the rotation of the rotating cam (230).

[0126] The rotating cam protrusion (232) may include a second anti-friction groove (2323) formed on an inclined surface between the rotating cam mountain (2321) and the rotating cam valley (2322). The second anti-friction groove (2323) may reduce the contact area between the rotating cam protrusion (232) and the fixed cam protrusion (222), thereby facilitating the rotation of the rotating cam (230).

[0127] Figures 14 and 15 are partial cross-sectional views of a refrigerator (1) according to one embodiment.

[0128] Referring to FIGS. 14 and 15, the plurality of doors (31, 32, 33, 34) may include a first door (31) and a second door (32). The first door (31) may include a first door gasket (31a) and a first gasket magnet (31b) provided inside the first door gasket (31a), and the second door (32) may include a second door gasket (32a) and a second gasket magnet (32b) provided inside the second door gasket (32a). The rotating bar (100) may include a rotating bar magnet (310) that magnetically interacts with the first door gasket (31a) magnet and the second gasket magnet (32b).

[0129] Referring to Fig. 14, the magnetic poles of the first gasket magnet (31b), the second gasket magnet (32b), and the rotary bar magnet (310) may be arranged in the same direction. For example, if the magnetic poles of the first gasket magnet (31b) and the second gasket magnet (32b) in the direction toward the main body (10) are N poles, the magnetic poles of the rotary bar magnet (310) in the direction toward the first gasket magnet (31b) and the second gasket magnet (32b) may be S poles.

[0130] Referring to Fig. 15, the magnetic directions of the first gasket magnet (31b) and the second gasket magnet (32b) and the magnetic direction of the rotary bar magnet (310) may be arranged in opposite directions. For example, when the first gasket magnet (31b) and the second gasket magnet (32b) are arranged in the order of the N pole and the S pole in the direction from the first door (31) toward the second door (32), the rotary bar magnet (310) may be arranged in the order of the S pole and the N pole in the direction from the first door (31) toward the second door (32).

[0131] The types, numbers, and directions of magnetic poles of the first gasket magnet (31b), the second gasket magnet (32b), and the rotary bar magnet illustrated in FIGS. 1 to 15 are merely examples. That is, it is sufficient if the first gasket magnet (31b), the second gasket magnet (32b), and the rotary bar magnet (310) are formed so as to form an attractive force between the rotary bar (100) and the first door (31), and between the rotary bar (100) and the second door (32).
