Definitions
- the present invention relates to a door hinge, and more particularly, to a door hinge capable of opening or closing a door smoothly by means of a damper when opening or closing a door, and capable of easily opening or closing a door with little force. .
- doors used in various electronic products such as cupboard doors of kitchen furniture, kimchi refrigerators, washing machines, and folding mobile phones mainly use bottom-up hinged doors that open and close upward and downward while rotating around a hinge axis.
- the hinge device used in such a bottom-up opening and closing door rotates while being mounted on the end of the door to close the door.
- a compression spring is installed in the door hinge, and the compression spring generates a compression force in a starting section in which the door closes, thereby slowing down the rotation speed of the shaft so that the door rotates slowly.
- the compressive force of the compression spring has a limit, and therefore, when the door is configured to support the load of the door with only one compression spring, as in the prior art, when the door continues to close, when it enters the progress section, it is more than enough to support the load of the door at this time.
- the rotational speed of the shaft cannot be effectively slowed down because a large compressive force cannot be generated.
- the present invention has been made to solve the above problems, and an object of the present invention is to provide a door hinge that can easily open and close the door.
- Another object of the present invention is to provide a door hinge capable of smoothly opening and closing a door by means of a damper.
- an object of the present invention is to provide a door hinge capable of opening and closing the door with little force by allowing the link axis to rotate while moving inside the hole around the hinge axis when the door rotates.
- Another object of the present invention is to provide a door hinge that prevents the door from being opened due to high heat from inside the main body.
- a door hinge of the present invention for achieving the above object includes an arm installed on the door and rotated; a housing installed on the main body of the mechanism provided with the door, connected to the arm by a hinge shaft, and including first and second openings provided at one side and a central portion;

It is characterized in that the sub roller is inserted.
- the door in addition to facilitating opening and closing of the door, the door can be stably opened and closed by allowing the door to be opened and closed smoothly by the compressive force of the damper.
- the link axis rotates due to the rotation of the door, the link axis rotates while moving inside the hole around the hinge axis, so that the door can be opened and closed with little force. That is, when the door is opened, since the link axis is far from the hinge axis, which is the central axis, the door is easily opened even if the user applies little force, and when the door is closed, since the link axis is close to the hinge axis, the user can easily apply little force even if the user applies It has the effect of closing the door.
- the problem of opening the door due to high heat from the inside of the main body can be solved. That is, the sub-spring part provided inside the housing is inserted into the recessed part of the arm, so that when the door is first opened, the door can be opened only when the user applies force.
