(54) A HINGE MECHANISM


(57) The present invention relates to a hinge mechanism (1) which enables to open and close the household appliance doors. The objective of the present invention is to provide a hinge mechanism (1) which enables the door to be closed and opened in a balanced way, and which prevents hard hitting by slowing down the door in case the door is closed fast and opened fast.




Description

Field of the Invention



[0001] The present invention relates to a hinge mechanism which enables to open and close the household appliance doors.

Background of the Invention



[0002] In appliances having doors such as oven, dishwasher, fridge, deep freezer; hinge mechanisms are used which enable the doors to be attached to the appliance body and to be opened and closed around an axis passing through these edges. The hinge systems comprise counterweight, spring systems in order to provide ease to the user while lifting doors, as well as they have the strength to carry appliance bodies having different door weights. Furthermore, there are hinge systems comprising damper in order to prevent the door from hitting the appliance body while closing or to prevent it from opening too fast with the weight of the door.

[0003] The United States patent document no. US20110017191, an application in the state of the art, discloses a hinge mounted to household appliances. The hinge comprises a damper in order to provide slow closing and opening. In the invention, it is stated that the hinge can comprise dampers, one for opening and one for closing.

[0004] The United States patent document no. US20120067333, an application in the state of the art, discloses a hinge mechanism for ovens. The hinge creates a closing force in order to keep the door in closed position. It comprises a damper resisting against this closing movement and slows it.

[0005] European Patent Document no EP2562341, an application known in the state of the art, discloses a damper system for hinges used in household appliances. The hinge slows down the door in order to prevent the door from hitting the body during closing.

[0006] The damper systems in the current technique cannot provide different force absorption in different positions of the door with the appliance. This situation causes insufficiencies in providing the desired comfort while closing or opening the door.

[0007] The mechanism used in transferring forces to the damper in the state of the art wear off in time due to their structure, and they cause the damper to be deformed in time.

Summary of the Invention



[0008] The objective of the present invention is to provide a hinge mechanism which connects the appliance and the door to each other and allows the door opening and closing freely by rotating around its axis.

[0009] Another objective of the present invention is to provide a hinge mechanism which enables the opening movement of the door in a controlled way by means of the weight of the door without requiring the user to apply force.

[0010] A further objective of the present invention is to provide a hinge mechanism which prevents the door or the appliance from getting damaged by preventing the excessively fast opening and closing movement of the door during closing and opening.

[0011] Yet another objective of the present invention is to provide a hinge mechanism which prevents the wearing of the hinge and elongates the life of the hinge by preventing the unwanted forces to occur during the transmission of the forces.

Detailed Description of the Invention



[0012] A hinge mechanism developed to fulfill the objectives of the present invention is illustrated in the accompanying figures, in which:

Figure 1 is the exploded view of the inventive hinge mechanism
