Definitions

  • the present invention relates to an oven hinge with shock absorber used in doors of the household appliances.
  • European Patent document no EP1847670 an application known in the state of the art, discloses a hinge produced to be used especially in electrical appliances. The force created during the door closing is absorbed right before the door is closed, so that the noise and the door hitting the electrical appliance strongly are prevented. But in the European patent document no EP1847670 , the movement received from the door is transferred to the damper using a lot of connectors. For this reason there are risks that can occur from the incompatibilities between the parts in the system of the European patent document no EP1847670 .
  • the movement received from the door is transferred to the damper with a single connector in order to solve the abovementioned problems.
  • Cost advantage is provided with reducing the part number. Since a single connector is used, the problems that can occur from the incompatibilities between the parts are eliminated.
  • WO2009033960 an application known in the state of the art, discloses a door hinge which is produced to be used in household appliances such as oven and dish washer.
  • the door can be brought to the vertical closed position from almost horizontal open position.
  • the hinge comprises a door lever that is mounted on a door, a housing which can be mounted on the carcass of a household appliance and to which the door lever is connected so as to be pivotable, a weight compensation spring, and a closing spring.
  • the closing spring applies a closing force right before the door is closed.
  • a damping device applies counter force to the closing force right before the door reaches the final position.
  • the device comprises at least one hinge, at least one element which generates closing force, at least one kinematic means which transforms the movement of the door to a reciprocal movement, and at least one damper which applies counter force to the closing force.
  • the objective of the present invention is to provide a household appliance with shock absorbing hinge which transfers the movement received from the hinge arm to the damper via a single connector.
  • a further objective of the present invention is to provide a shock absorbing oven hinge which prevents noise while the door is closing and opening and slows down the fast movement during closing.
  • the inventive household appliance (1) comprises a body of the appliance (2) which fulfills the main function of the household appliance (1) and has an opening, at least one door (3) which enables the opening on the body of the appliance (2) to be closed.
  • the inventive household appliance (1) comprises at least one hinge (4) having
  • the body of the appliance (2) is the part of the household appliance (1) which fulfills the function. There is an opening on the body of the appliance (2) enabling access inside the household appliance (1).
  • the door (3) enables the opening on the body of the appliance (2) to be closed and opened.
  • the hinge (4) absorbs the applied force right before the door (3) is closed in order to prevent the door (3) from hitting the body of the appliance (2) strongly and the noise during closing the door (3).
  • the body of the hinge (5) supports the components constituting the said hinge (4) and is fixed to the household appliances (1) such as oven, dish washer. There is at least one nail (53) present at the end of the body of the hinge (5) extending inside the household appliance (1).
  • the main spring (6) is a spring one end of which is attached to the nail (53) at one end of the body of the hinge (5) and the other end is attached to the main spring holder (7) enabling the connection between the main spring (6) and the door (3) via the first pin (14).
  • the end of the main spring holder (7) which is not connected to the main spring (6) is attached to the arm (13) enabling the connection of the hinge (4) to the door (3) preferably via a rivet such that it can rotate around the rivet.
  • the ends of the first pin (14) enabling the connection of the main spring (6) and the main spring holder (7) with each other are placed into the primary slots (51) on both sides of the body of the hinge (5) such that they can move therein.
  • the main spring holder (7) moves with the arm (13) and enables the first pin (14) to move along the primary slots (51), thus causes the main spring (6) to stretch or come loose.
  • the main spring (6) stretches while the door (3) is opening, and while the door (3) is closing the force originating from the stress generated in the main spring (6) helps the door (3) to close and enables the door (3) to remain fixed without applying any force at one point between completely open or completely closed positions.
  • the small spring (8) applies counter force against the force applied by the main spring (6) while the door (3) is closing and the force applied by the person closing the door (3). While the door (3) is being brought to completely closed position from completely open position, after a certain point the small spring (8) starts to compress and applies counter force. When it is continued to bring the door (3) to completely closed position, after a certain point the small spring (8) does not compress more and after this point the small spring (8) starts to apply force helping the door (3) to be closed.
  • the small spring holder (9) is a component one end of which is passed through the small spring (8) in order to support small spring (8) and compress the small spring (8).
  • the end of the small spring holder (9) which is not passed through the small spring (8) has a shape that cannot pass through the small spring (8).
  • the roller (10) is preferably a cylindrical structure which is positioned such that it can move inside the secondary slots (52) located on both sides of the body of the hinge (5).
  • the middle part of the roller (10) contacts the end of the small spring holder (9) which is not passed through the small spring (8).
  • the roller (10) starts to move inside the secondary slots (52) towards the side of the hinge of the body (5) which has nail (53) on its end.
  • the movement of the roller (10) inside the secondary slots (52) enables the small spring holder (9) which the roller (10) contacts to move in the same direction and thus the small spring (8) starts to be compressed.
  • the damper (11) prevents the door (3) from hitting the body of the appliance (2) strongly by absorbing the force generated right before the door (3) is closed.
  • the slider (12) is the component which transfers the movement it receives from the door (3) to the damper (11) directly during bringing the door (3) from open position to closed position.
  • One end of the slider (12) which is placed inside the body of the hinge (5) such that it can move back and forth along the body of the hinge (5) contacts the piston of the damper (11).
  • the slider (12) starts to move towards the damper (11).
  • the movement of the slider (12) towards the damper (11) causes the piston of the damper (11) to go inside the damper (11).
  • the damper (11) absorbs some part of the force generated during closing the door (3).
  • the arm (13) is a component one end of which is fixed to the door (3) and the other end is connected to the body of the hinge (5) via a pipe pin (15) such that it can rotate around the pipe pin (15).
  • There are two protrusions being first protrusion (16) and second protrusion (17) which are for activating the roller (10) and the slider (12) respectively, on the side of the arm (13) which is connected to the body of the hinge (5).
  • the arm (13) rotates around the pipe pin (15) with the movement of the door (3) while the door (3) is being closed and opened. While the door (3) is being brought to completely close position from completely open position, primarily the first protrusion (16) contacts the roller (10).
  • the first protrusion (16) starts to move the roller (10) inside the secondary slots (52) inside the body of the hinge (5).
  • the roller (10) moving inside the secondary slots (52) starts to move the small spring holder (9) contacting the middle point of the roller (10) such that it will compress the small spring (8).
  • the small spring (8) which starts to be compressed applies counter force against the force applied by the main spring (6) helping the door (3) to be closed.
  • the second protrusion (17) located on the arm (13) contacts the slider (12) and activates the slider (12).
  • the first protrusion (16) cannot move the roller (10) such that it will cause the small spring (8) to be compressed more because of the shape of the first protrusion (16).
  • the small spring (8) which is compressed from the moment that the second protrusion (17) contacts the slider (12) starts to apply force that will help to close the door (3) because of the shape of the first protrusion (16). If the door (3) is continued to be brought to completely closed position after the second protrusion (17) contacts the slider (12), the second protrusion (17) starts to move the slider (12) by pushing and the piston of the damper (11) touching the end of the slider (12) which the second protrusion (17) does not contacts starts to go inside the damper (11).
  • the damper (11) enables the door (3) to be closed relatively slow. From the moment that the second protrusion (17) contacts the slider (12) during the movement continuing until the door (3) is completely closed, the forces generated by the main spring (6) and the small spring (8) are absorbed and relatively slow closing is enabled.
  • the movement made by the door (3) is transferred to the damper (11) by using single connector called as slider (12) above.
  • the arm (13) fixed to the door (3) activates both the roller (10) and thus the small spring (9) with single movement of the door (3) and the slider (12) and thus the damper (11).
  • the main spring (6) is in stretched position and applies force trying to close the door (3) to the arm (13) via the main spring holder (7) one end of which is connected to the arm (13) and the other end is connected to the main spring (6).
  • the second protrusion (17) contacts the slider (12) and starts to move the slider (12).
  • the small spring (8) reaches the point where it is compressed the most and the small spring (8) starts to apply force helping to close the door (3) because of the shape of the first protrusion (16) from this moment as long as the door (3) is continued to be brought to completely closed position.
  • the piston of the damper (11) contacting the end of the slider (12) which the second protrusion (17) does not contact enables the door (3) to be closed relatively slow by moving inside the damper (11) with the movement of the slider (12).
  • the household appliance (1) is an oven.
  • the household appliance (1) is a dish washer.
  • the household appliance (1) is a microwave oven.
  • inventive household appliance (1) It is possible to develop various embodiments of the inventive household appliance (1).
  • the invention can not be limited to the examples described herein and it is essentially as defined in the claims.
