Description
CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2023-0001754, filed in Korea on Jan. 5, 2023, whose entire disclosure is hereby incorporated by reference.


BACKGROUND
1. Field

The present disclosure relates to a refrigerator.


2. Background

In general, a refrigerator is a home appliance that allows food to be stored at low temperatures in a storage space. To this end, refrigerators are designed to keep stored food in optimal condition by cooling the inside of the storage space using cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle.


Recently, refrigerators equipped with various structures and convenience devices that take user convenience into consideration have been released. In addition, as refrigerators become larger and more multi-functional, the requirements for safety standards and safety devices are being strengthened.


However, there are still some shortcomings in safety devices as refrigerators become larger and more multi-functional. For example, if the refrigerator door is closed too hard, the door may hit the main body of the refrigerator hard, creating a collision noise. Additionally, if the door hits the main body strongly and your fingers are caught, there is a risk of serious injury due to the collision force.


In Republic of Korea Patent Publication No. 10-0596246, a damper structure that can adjust the opening and closing speed of a door is disclosed.


However, this damper may be mounted in a fixed state on the cabinet to control the door closing speed. At this time, in the case of a built-in refrigerator placed adjacent to surrounding furniture, there is a problem in that it is difficult to separate and assemble when a service situation occurs in the future.

In detail, the first damping device 40a may be provided with a non-damping section in which the damping force is reduced in a section in contact with the pillar 30 in the middle of the point where the door is closed. The second damping device 40b may be configured so that the damping force increases consistently depending on the section in which the door is closed.


The hinge device 24 may include a first hinge device 24a connected to the first upper door 21a and a second hinge device 24b connected to the second upper door 21b. The first hinge device 24a and the second hinge device 24b may have different structures depending on need. Of course, the first hinge device 24a and the second hinge device 24b may have the same structure.


The refrigerator 1 may further include a door opening device for pushing the hinge device 24 to operate the hinge device 24 to rotate the door 20.


The refrigerator 1 may include a cover plate 14 disposed on the upper surface of the cabinet 10 to be spaced upward. The cover plate 14 may be formed to cover at least a portion of the hinge device 24 across the pair of hinge devices in the horizontal direction.


A PCB module 16 that controls settings of the refrigerator 1 may be mounted on the upper surface of the cabinet 10.


The refrigerator 1 of the present disclosure can be built into kitchen furniture. For example, a furniture cabinet may be installed in a kitchen or a specific space, and a refrigerator 1 may be accommodated within the furniture cabinet. Of course, even when the refrigerator 1 is used in a non-built-in state, the technology for the hinge device 24 and the damping device 40 of the present disclosure can be applied as it is.


Meanwhile, the present disclosure is not limited to the form described above and can be applied to all types of refrigerators equipped with a door.

The damping device 40 may further include a first elastic member 48 that elastically supports the movable member 47, and a second elastic member 49 that provides elastic force so that the cylinder 43 protrudes out of the housing 41.


In a state where no external force is applied to the cylinder 43, the cylinder 43 protrudes outward from the housing 41 to the maximum extent by the second elastic member 49. When an external force is applied to the cylinder 43, oil flows toward the movable member 47. When oil passes through the oil flow path portion 45, the cylinder 43 moves in a direction toward being introduced into the housing 41. In this process, a damping force is generated to reduce the closing speed of the door 20.


Meanwhile, the damping device 40 includes a first damping device 40a applied to the first upper door 21a with a filler 30, and a second damping device 40b applied to the second upper door 21b without a filler 30, which may be different from each other.


For example, the first damping device 40a may further include an expansion portion 432. The first damping device 40a may further include an expansion portion 432 that divides the damping section A and the non-damping section B. The non-damping section B is a section where the filler is in contact during the door closing process and may be a section where the damping force of the damping device 40 is reduced compared to the damping force of the damping section A.


In detail, the non-damping section B may have a larger diameter of the cylinder 43 than the damping section A due to the expansion portion 432. The contact portion 431 may be provided with a non-damping section B in which the contact portion 431 is not contacted by the expansion portion 432 inside the cylinder.


Through this, the door 20 can be closed in the section where the pillar 30 is in contact without interference from the damping device 40.


Meanwhile, the second damping device 40b may not be provided with such an expansion portion 432. Accordingly, the cylinder 43 can be formed to have a constant diameter in the sliding direction. In this case, as the door 20 is closed, the damping force may gradually increase.


In this way, the first upper door 21a and the second upper door 21b may be provided with a first damping device 40a and a second damping device 40b having different structures, respectively. Additionally, a first hinge device 24 and a first damping device 40a may be mounted on the first bracket module 50a. A second hinge device 24 and a second damping device 40b may be mounted on the second bracket module 50b. At this time, the first bracket module 50a and the second bracket module 50b each have a fool proof structure to prevent mixing during the assembly process.



FIG. 10 is a view to explain a state where the damper device operates during the door closing process.


In the process of closing the door 20 by the user, the closing force of the door 20 is provided by the damping device 40. In other words, a portion of the hinge device 24 presses the cylinder 43 of the damping device 40.


Then, the oil passes through the oil flow path portion 45. The movable member 47 moves in a direction away from the oil flow path portion 45 due to the oil passing through the oil flow path portion 45. When the oil flow path portion 45 is located in the damping section of the cylinder 43, a damping force is generated in the damping device 40. The closing speed of the door 20 is reduced by the damping force, allowing the door 20 to close smoothly.


Meanwhile, in one embodiment, it has been described that the damping device 40 is in contact with the hinge device 24, but unlike this, it is also possible for the damping device 40 to be directly in contact with the door 20.


This embodiment provides a refrigerator whose door can be closed smoothly during the process of opening and closing the refrigerator door.


This embodiment provides a refrigerator in which the problem of door sagging due to door weight is improved.
