Description

Technical Field

[0001] The present invention relates to an insulator. The present invention relates to a refrigerator having an insulator.Background Art

[0002] A refrigerator is configured to include a refrigerator main body in which a storage chamber for storing food is provided, and a door for opening and closing the storage chamber. The Refrigerator main body includes a cold supply device capable of supplying cold air to the storage chamber. The refrigerator main body includes an outer case forming an exterior, an inner case spaced apart on one side of the outer case, and a heat-insulating part charged between the outer case and the inner case. In conventional refrigerators, there is a problem that a heat-insulating part including a wall of a storage chamber of the refrigerator has a relatively large thickness, so that the storage chamber becomes relatively small compared to a size of an exterior appearance.Disclosure Technical Problem

[0003] Therefore, an object of the present invention is to provide a refrigerator having a vacuum insulator that may reduce a wall thickness and loss of cold air of a storage chamber and may smoothly support a drawer.

[0004] Another object of the present invention is to provide a refrigerator having a vacuum insulator, which may prevent interference between internal components when installing the drawer.Technical Solution

[0005] An insulator of the present invention may be provided as at least one insulator. As an example, the insulator may provide a first wall extending in one direction; and a second wall extending in a direction different from the one direction. As another example, the insulator may include a first insulator and a second insulator. The second insulator may be provided as a separate component separated from the first insulator. The second insulator may include a part extending in the same direction as the first insulator. The second insulator may include a part extending in a different direction from the first insulator. The insulator may be provided in the form of a panel.

[0006] A refrigerator of the present invention may include at least one panel. The plurality of panels may be connected by joints. The present invention may include a first panel forming a first surface (e.g., side surface) of the refrigerator. Optionally, the present invention may include a second panel forming a second surface (e.g., rear surface) of the refrigerator. Optionally, the present invention may include a third panel forming a third surface (e.g., top surface) of the refrigerator. Optionally, the present invention may include a fourth panel forming a fourth surface (e.g., bottom surface) of the refrigerator. Each of the first, second, third, and fourth panels may be provided in plurality. The panel may be an insulator or a vacuum insulator. The first panel may include one of the first panels forming one of the first surfaces of the refrigerator, and the other one of the first panels forming the other one of the second surfaces of the refrigerator. At least one of the first, second, third, and fourth panels may provide at least a part of a wall forming a storage chamber of the refrigerator. At least one of the first, second, third, and fourth panels may provide at least a part of a wall forming a main body of the refrigerator.

[0007] Optionally, the present invention may be provided with joints provided at corners forming boundaries of the at least two panels. The first panel may include a first plate disposed to face the storage chamber; a second plate forming a vacuum space part with the first plate; and a vacuum space part provided between the first plate and the second plate. Accordingly, since the storage chamber is formed by assembly of at least two panels, relatively small facilities may be required when manufacturing the refrigerator main body and manufacturing can be easily accomplished. By providing the joints at the corners of at least two panels that are assembled to each other, cold air leakage through the corners of the storage chamber can be inhibited. Since the first panels provided on both sides of the storage chamber are configured as vacuum insulators, a wall thickness of the storage chamber can be reduced. Here, when the refrigerator main body has the same exterior size, a storage capacity of the storage chamber can be increased by an amount of the wall thickness which is reduced.

[0008] Optionally, the present invention may be provided with a drawer guide for guiding a drawer in the panel. By providing the drawer guide for slidably guiding the drawer in the panel, the wall thickness of the storage chamber can be reduced, cold air leakage through the corners of the storage chamber can be inhibited, and sliding of the drawer can be performed smoothly.

[0009] Optionally, a coupling plate part that is coupled to the first panel may be provided in the drawer guide. The drawer guide may include a drawer support part that protrudes from the coupling plate part and supports the drawer. Accordingly, a contact area between the drawer guide and the first panel may be increased so that a load of the drawer may be distributed and supported. The coupling plate part may include a plate body. The coupling plate part may include a support rib that protrudes from the body and extends to one side. The support rib may be implemented in plurality. Accordingly, a thickness of the body can be reduced, and a strength of the body can be increased.

[0010] Optionally, a component coupler coupling the drawer guide may be provided in the first panel. The component coupler may include a plate that is coupled to the first panel. The component coupler may include a bolt that protrudes from the plate. The drawer guide is provided with a bolt-receiving part configured to receive the bolt. Accordingly, coupling between the first panel and the drawer guide can be smoothly achieved. Here, a first plate of the first panel is configured as a thin plate, and the plate of the component coupler may be connected to the first plate of the first panel. Accordingly, occurrence of damage to the first panel can be inhibited.

[0011] Optionally, a coupling plate part that is coupled to the first panel may be provided in the drawer guide. The drawer guide may include a drawer support part protruding from the coupling plate and supporting the drawer. The drawer guide may include a cell having an opened surface facing the first panel in the coupling plate part. Accordingly, when the drawer guide is coupled, the opening of the cell is blocked by the first panel, so that insulation of the first panel is reinforced and cold air leakage can be inhibited. By providing the cell on the surface of the coupling plate part, a supporting strength of the drawer guide can be increased.

[0012] Optionally, a heat-insulating part formed by placing a heat-insulating material on a surface of the coupling plate part facing the first panel may be provided in the drawer guide. Accordingly, when the drawer guide is coupled, the insulation of the first panel may be reinforced by the heat-insulation part. The supporting strength of the drawer guide can be increased by the heat-insulating part. The heat-insulating material may be made of Expanded Polystyrene (EPS). The heat-insulation material may include polyurethane foam foamed by filling with a foaming liquid.

[0013] Optionally, the refrigerator of the present invention may include a partition wall partitioning the storage chamber into a first storage chamber and a second storage chamber. The drawer guide may include a first storage chamber drawer guide provided in the first storage chamber. The first storage chamber drawer guide may include a first plate disposed to correspond to the first panel. The first storage chamber drawer guide may connect a bottom part of the first plate. The first storage chamber drawer guide may include a second plate placed on the partition wall. The first storage chamber drawer guide may include a third plate placed on one end of the first plate. Accordingly, use of a component coupler for coupling the drawer guide and the first panel can be excluded. One end of the first plate may be supported by the third plate. When a drawer provided on one side (e.g., lower side) of the third plate is stored, a part (e.g., upper side) of the drawer may be blocked.

[0014] Optionally, the first storage chamber drawer guide may include a fourth plate disposed between the third plate and the second plate. A drawer support part supporting a drawer stored in at least one of one side (e.g., upper side) and the other side (e.g., lower side) of the fourth plate is formed in the first plate. Accordingly, the drawer can be stored in at least one of a one side (e.g., upper side) space and the other side (e.g., lower side) space partitioned in one direction (e.g., vertically) by the fourth plate.

[0015] Optionally, any one of the third plate and the fourth plate is implemented as a glass panel. Accordingly, observation of an interior of the drawer can be easily accomplished without withdrawing the drawer stored on one side (e.g., lower side) of the glass panel. At least one of the third plate and the fourth plate is implemented as the glass panel. The first plate may include a plate body. The first plate is configured to include a support rib protruding from a surface of the body facing the first panel, and extending to one side. Accordingly, a thickness of the body can be reduced and a support strength of the body can be increased. When the first plate and the first panel are connected, an air layer is formed between the at least two support ribs or movement of air is inhibited, and as a result, heat insulation reinforcement of the first panel can be accomplished.

[0016] In an embodiment of the present invention, the support ribs may be implemented as a first rib and a second rib that cross each other. The first ribs may be provided in plurality and disposed in parallel to each other. The second ribs may be provided in plurality and disposed in parallel to each other. Accordingly, cells may be formed between the first ribs and the second ribs. According to such a configuration, when the first plate and the first panel are connected, openings of the cells are blocked by the first panel, and as a result, the movement of the air can be more effectively inhibited.

[0017] In an embodiment of the present invention, the at least two panels may include a second panel provided on a second surface of the storage chamber.

A return duct coupling part cut out to be coupled to the return duct is provided on the first plate of the first storage chamber drawer guide.

The second storage chamber drawer guide is configured to include a joint part formed of the insulating material and bent from an end portion of the coupling plate part to be connectable to the first plate of the second panel.

[0024] Accordingly, cold air leakage at boundary regions of the second storage chamber drawer guide and the first joint can be inhibited.

[0025] In an embodiment of the present invention, the second storage chamber drawer guide is configured to include a heat-insulation reinforcement part formed by filling with a heat-insulating material on a surface of the coupling plate part facing the first panel.

[0026] Accordingly, a heat-insulation performance of the region of the first panel can be improved.

[0027] In an embodiment of the present invention, the refrigerator includes a second storage chamber door provided in the refrigerator main body, and opening and closing an opening of the second storage chamber, and an inclined part which is inclined is provided at an end portion of the second storage chamber drawer guide.

[0028] Accordingly, connection between the second storage chamber drawer guide and the second storage chamber door can be inhibited.

The fourth panel may include a first protrusion part protruding from the fourth panel body in a first direction.

[0189] The first support rib 24221 has, for example, a closed loop shape corresponding to an corner shape of the body 2421.

[0190] Accordingly, an empty space (cell 24223) having an opening on the first panel (141) side may be formed inside the support rib 2422 (first support rib 24221).

[0191] According to such a configuration, when the first storage chamber drawer guide 241 and the first panel 141 are coupled, an opening of the internal empty space (cell 24223) of the support rib 2422 of the first storage chamber drawer guide 241 may be blocked by the first panel 141.

[0192] Accordingly, air movement of the internal empty spaces (cells 24223) of the support rib 2422 may be inhibited and heat-insulating performance may be improved.

[0193] The empty space formed by the first support rib 24221 may be partitioned into a plurality of empty spaces (cells) by the second support rib 24222.

[0214] A unidirectional length (e.g., front-to-rear width) of the first coupling plate part 24121 is formed smaller than a unidirectional length (e.g., front-to-rear width) of the second coupling plate part 24111.

[0215] The first coupling plate part 24121 may be formed to have a relatively thinner thickness than the second coupling plate part 24111.

[0216] The second coupling plate part 24111 may have a thicker thickness than the first coupling plate part 24121.

[0217] Accordingly, a support strength of the second region of the first storage chamber drawer guide 241 is increased, and the second sub chamber drawer 2012, the second glass panel 2052, the first sub chamber drawer 2011, and the first glass panel 2051 may be stably supported.

Technical Field

[0001] The present invention relates to an insulator. The present invention relates to a refrigerator having an insulator.Background Art

[0002] A refrigerator is configured to include a refrigerator main body in which a storage chamber for storing food is provided, and a door for opening and closing the storage chamber. The Refrigerator main body includes a cold supply device capable of supplying cold air to the storage chamber. The refrigerator main body includes an outer case forming an exterior, an inner case spaced apart on one side of the outer case, and a heat-insulating part charged between the outer case and the inner case. In conventional refrigerators, there is a problem that a heat-insulating part including a wall of a storage chamber of the refrigerator has a relatively large thickness, so that the storage chamber becomes relatively small compared to a size of an exterior appearance.Disclosure Technical Problem

[0003] Therefore, an object of the present invention is to provide a refrigerator having a vacuum insulator that may reduce a wall thickness and loss of cold air of a storage chamber and may smoothly support a drawer.

[0004] Another object of the present invention is to provide a refrigerator having a vacuum insulator, which may prevent interference between internal components when installing the drawer.Technical Solution

[0005] An insulator of the present invention may be provided as at least one insulator. As an example, the insulator may provide a first wall extending in one direction; and a second wall extending in a direction different from the one direction. As another example, the insulator may include a first insulator and a second insulator. The second insulator may be provided as a separate component separated from the first insulator. The second insulator may include a part extending in the same direction as the first insulator. The second insulator may include a part extending in a different direction from the first insulator. The insulator may be provided in the form of a panel.

[0006] A refrigerator of the present invention may include at least one panel. The plurality of panels may be connected by joints. The present invention may include a first panel forming a first surface (e.g., side surface) of the refrigerator. Optionally, the present invention may include a second panel forming a second surface (e.g., rear surface) of the refrigerator. Optionally, the present invention may include a third panel forming a third surface (e.g., top surface) of the refrigerator. Optionally, the present invention may include a fourth panel forming a fourth surface (e.g., bottom surface) of the refrigerator. Each of the first, second, third, and fourth panels may be provided in plurality. The panel may be an insulator or a vacuum insulator. The first panel may include one of the first panels forming one of the first surfaces of the refrigerator, and the other one of the first panels forming the other one of the second surfaces of the refrigerator. At least one of the first, second, third, and fourth panels may provide at least a part of a wall forming a storage chamber of the refrigerator. At least one of the first, second, third, and fourth panels may provide at least a part of a wall forming a main body of the refrigerator.

[0007] Optionally, the present invention may be provided with joints provided at corners forming boundaries of the at least two panels. The first panel may include a first plate disposed to face the storage chamber; a second plate forming a vacuum space part with the first plate; and a vacuum space part provided between the first plate and the second plate. Accordingly, since the storage chamber is formed by assembly of at least two panels, relatively small facilities may be required when manufacturing the refrigerator main body and manufacturing can be easily accomplished. By providing the joints at the corners of at least two panels that are assembled to each other, cold air leakage through the corners of the storage chamber can be inhibited. Since the first panels provided on both sides of the storage chamber are configured as vacuum insulators, a wall thickness of the storage chamber can be reduced. Here, when the refrigerator main body has the same exterior size, a storage capacity of the storage chamber can be increased by an amount of the wall thickness which is reduced.

[0008] Optionally, the present invention may be provided with a drawer guide for guiding a drawer in the panel. By providing the drawer guide for slidably guiding the drawer in the panel, the wall thickness of the storage chamber can be reduced, cold air leakage through the corners of the storage chamber can be inhibited, and sliding of the drawer can be performed smoothly.

[0009] Optionally, a coupling plate part that is coupled to the first panel may be provided in the drawer guide. The drawer guide may include a drawer support part that protrudes from the coupling plate part and supports the drawer. Accordingly, a contact area between the drawer guide and the first panel may be increased so that a load of the drawer may be distributed and supported. The coupling plate part may include a plate body. The coupling plate part may include a support rib that protrudes from the body and extends to one side. The support rib may be implemented in plurality. Accordingly, a thickness of the body can be reduced, and a strength of the body can be increased.

[0010] Optionally, a component coupler coupling the drawer guide may be provided in the first panel. The component coupler may include a plate that is coupled to the first panel. The component coupler may include a bolt that protrudes from the plate. The drawer guide is provided with a bolt-receiving part configured to receive the bolt. Accordingly, coupling between the first panel and the drawer guide can be smoothly achieved. Here, a first plate of the first panel is configured as a thin plate, and the plate of the component coupler may be connected to the first plate of the first panel. Accordingly, occurrence of damage to the first panel can be inhibited.

[0011] Optionally, a coupling plate part that is coupled to the first panel may be provided in the drawer guide. The drawer guide may include a drawer support part protruding from the coupling plate and supporting the drawer. The drawer guide may include a cell having an opened surface facing the first panel in the coupling plate part. Accordingly, when the drawer guide is coupled, the opening of the cell is blocked by the first panel, so that insulation of the first panel is reinforced and cold air leakage can be inhibited. By providing the cell on the surface of the coupling plate part, a supporting strength of the drawer guide can be increased.

[0012] Optionally, a heat-insulating part formed by placing a heat-insulating material on a surface of the coupling plate part facing the first panel may be provided in the drawer guide. Accordingly, when the drawer guide is coupled, the insulation of the first panel may be reinforced by the heat-insulation part. The supporting strength of the drawer guide can be increased by the heat-insulating part. The heat-insulating material may be made of Expanded Polystyrene (EPS). The heat-insulation material may include polyurethane foam foamed by filling with a foaming liquid.

[0013] Optionally, the refrigerator of the present invention may include a partition wall partitioning the storage chamber into a first storage chamber and a second storage chamber.

The first storage chamber drawer guide may include a second plate placed on the partition wall. The first storage chamber drawer guide may include a third plate placed on one end of the first plate. Accordingly, use of a component coupler for coupling the drawer guide and the first panel can be excluded. One end of the first plate may be supported by the third plate. When a drawer provided on one side (e.g., lower side) of the third plate is stored, a part (e.g., upper side) of the drawer may be blocked.

[0014] Optionally, the first storage chamber drawer guide may include a fourth plate disposed between the third plate and the second plate. A drawer support part supporting a drawer stored in at least one of one side (e.g., upper side) and the other side (e.g., lower side) of the fourth plate is formed in the first plate. Accordingly, the drawer can be stored in at least one of a one side (e.g., upper side) space and the other side (e.g., lower side) space partitioned in one direction (e.g., vertically) by the fourth plate.

[0015] Optionally, any one of the third plate and the fourth plate is implemented as a glass panel. Accordingly, observation of an interior of the drawer can be easily accomplished without withdrawing the drawer stored on one side (e.g., lower side) of the glass panel. At least one of the third plate and the fourth plate is implemented as the glass panel. The first plate may include a plate body. The first plate is configured to include a support rib protruding from a surface of the body facing the first panel, and extending to one side. Accordingly, a thickness of the body can be reduced and a support strength of the body can be increased. When the first plate and the first panel are connected, an air layer is formed between the at least two support ribs or movement of air is inhibited, and as a result, heat insulation reinforcement of the first panel can be accomplished.

[0016] In an embodiment of the present invention, the support ribs may be implemented as a first rib and a second rib that cross each other. The first ribs may be provided in plurality and disposed in parallel to each other. The second ribs may be provided in plurality and disposed in parallel to each other. Accordingly, cells may be formed between the first ribs and the second ribs. According to such a configuration, when the first plate and the first panel are connected, openings of the cells are blocked by the first panel, and as a result, the movement of the air can be more effectively inhibited.

[0017] In an embodiment of the present invention, the at least two panels may include a second panel provided on a second surface of the storage chamber.

The second storage chamber drawer guide is configured to include a joint part formed of the insulating material and bent from an end portion of the coupling plate part to be connectable to the first plate of the second panel.

[0024] Accordingly, cold air leakage at boundary regions of the second storage chamber drawer guide and the first joint can be inhibited.

[0025] In an embodiment of the present invention, the second storage chamber drawer guide is configured to include a heat-insulation reinforcement part formed by filling with a heat-insulating material on a surface of the coupling plate part facing the first panel.

[0026] Accordingly, a heat-insulation performance of the region of the first panel can be improved.

[0215] The first coupling plate part 24121 may be formed to have a relatively thinner thickness than the second coupling plate part 24111.

[0216] The second coupling plate part 24111 may have a thicker thickness than the first coupling plate part 24121.
