OR HINGES
Field of the Invention
The present invention relates to a deceleration mechanism which eliminates the comfort and sound problems caused by the fast/harsh closing of the door that are used to cover the built-in household appliances, and the damage to the hinge, door and device caused by harsh closing.
Background of the Invention
Built-in household appliances, especially washing machines, are placed inside a cabinet. There are hinge mechanisms which enable the doors of the cabinets that are used to access the household appliances placed in the built-ins to fulfill their opening and closing function. In said hinge mechanisms, the moments necessary for the closing of the door are provided by a spring located inside the hinge, the door accelerates after a certain angle and self-closing occurs. In the hinges used in the state of the art, the door closes fast due to the forces generated by the spring and the door hits the device harshly. This results in an uncomfortable closing action and a loud noise. In addition, the door closes fast with the forces generated by the spring, the case of a hard impact on the appliance causes damage to the hinge, the door and the front surface of the appliance, and it causes the hinge to lose its function in a short time, problems on the door and aesthetic problems on the appliance.

In the deceleration mechanism (1) of the present invention, a body (3) is positioned on/inside a surface of the household appliance for decelerating the door, which is placed in front of the household appliance, and which is opened and closed by means of a cabinet hinge (2), in order to prevent damage to the household appliance. A guide (6) is positioned on the body (3) and there is a bearing cavity (62) inside the guide (6). A primary slot (61) is made on the guide (6). There is a pin (7) which is positioned to move linearly along the bearing cavity (62) inside the guide (6) and has a length longer than the length of the guide (6). A secondary slot (71) is made on the pin (7) to be parallel with the primary slot (61). There is a pusher arm (51) which is provided on the cam body (5) and is positioned so that it passes through the primary slot (61) and the secondary slot (71), which contacts the secondary slot (71) thereby transferring the load on the pin (7) to the absorber (4).
In the deceleration mechanism (1) of the present invention, a body (3) is positioned on a connection surface of the household appliance for decelerating the door, which is placed in front of the household appliance and which is opened and closed by means of a cabinet hinge (2), in order to prevent damage to the household appliance. A pin (7) extends over the body (3) and during the closing of the door, the door comes into contact with the pin (7). The linear load generated during the closing of the door is transferred to the pin (7). The pin (7), which can move linearly in the bearing cavity (62) inside the guide (6), transfers the said lineal- load to the pusher arm (51) which is located inside the second slot (71) and which contacts the inner walls of the secondary slot. The pusher cam (51) transfers the linear load thereon to the absorber (4) by moving circularly around the point where the cam body (5) is connected to the body (3). In other words, the cam body (5), the other end of which is connected to the absorber (4), transfers the load thereon to the absorber (4) through the first arm (52) by moving circularly around the point where it is connected to the body (3). One end of the absorber (4) is connected to the cam body (5), and its other end is connected to the body (3) and it is comprised of interlocking parts, by this means it absorbs the load applied thereon by moving telescopically. Thanks to absorbing the load generated during closing of the door, the door is closed without damaging the household appliance.
In a preferred embodiment of the invention, in the deceleration mechanism (1) of the present invention, there is a connection surface provided preferably on the front side of the household appliance. There is a door for covering the connection surface. There is a cabinet hinge (2), one end of which is connected to the connection surface and the other end to the door, in order for the door covering the connection surface to move. Thanks to the cabinet hinge (2), the door can move around the point where the cabinet hinge (2) is attached. There is a body (3) connected onto the connection surface. The body (3) is preferably positioned on the cabinet hinge (2). An absorber (4), a cam body (5) and a guide (6) are positioned on the body (3) which has a planar surface. One end of the absorber (4), which has a hydraulic structure to absorb the load when a load is placed on it, is connected on the body (3), and the absorber (4) can move circularly around the point where it is connected, and the other end of the absorber (4) is connected to the cam body (5). The other end of the absorber (4) which is connected to the cam body (5) can move circularly around the point where it is connected. One end of the cam body (5), which has two ends, is connected to the body (3), and its other end is connected to the absorber (4). The cam body (5) can move circularly around the points where it is connected. A guide (6) is positioned on the body (3) and there is a bearing cavity (62) inside the said guide (6). A primary slot (61) is made on the guide (6). There is a pin (7) which is positioned to move linearly along the bearing cavity (62) inside the guide (6) and has a length longer than the length of the guide (6). The said pin (7) partially contacts the door moving via the cabinet hinge (2). In other words, the door moving via the cabinet hinge (2) contacts the pin (7) during covering the connection surface. A secondary slot (71) is made on the pin (7) to be parallel with the primary slot (61). The cam body (5) comprises at least one pusher arm (51) provided thereon, which is located such that it will pass through the secondary slot (71).
A deceleration mechanism (1), comprising a household appliance body (A) and at least one door that can be closed on the household appliance body, and used for decelerating the door in order to prevent the hinged door of the household appliance from damaging the household appliance during closing, comprises at least one absorber (4) which is connected to one side on/inside the appliance body part corresponding to the door of the appliance and which can move rotatably around its point of attachment, at least one cam body (5) which is fixed on the appliance body (3) on its one side in a rotatable manner and extends over the absorber (4) on the other side and which comprises a first arm (52) connected to the absorber, and which can move circularly around the points it is connected to, at least one guide (6) which is placed on/inside the appliance body and comprises a bearing cavity (62) and at least one primary slot (61) made thereon in the form of a through channel, at least one pin (7) which is positioned to move linearly along the bearing cavity (62) located inside the guide (6) upon the closing movement of the door, and on which the door or a part located on the door contacts, a secondary slot (71) which is made on the pin (7) to coincide with the primary slot (61), at least one pusher arm (51) which is provided on the cam body (5) and is positioned so that it passes through the primary slot (61) and the secondary slot (71), which contacts the secondary slot (71) thereby transferring the load on the pin (7) to the absorber (4).
In the deceleration mechanism (1) of the present invention, an absorber is positioned rotatably inside/on the said household appliance body. The joint cam part is fixed to the inside of the appliance body with a joint/pin or rotating element and is connected onto the absorber by a first arm (52) extending to the absorber from one side of the part where it is fixed via the joint/pin, and it comprises a pusher arm (51) extending over it at its other side. A guide (6) is positioned on the surface of the appliance body (3) on which the door is closed, and there is a bearing cavity (62) inside the guide (6). A primary slot (61) is made on the guide (6). There is a pin (7) which is positioned to move linearly along the bearing cavity (62) inside the guide (6) and has a length longer than the length of the guide (6). A secondary slot (71) is made on the pin (7) to be parallel with the primary slot (61). There is a pusher arm (51) which is provided on the cam body (5) and is positioned so that it passes through the primary slot (61) and the secondary slot (71), which contacts the secondary slot (71) thereby transferring the load on the pin (7) to the absorber (4). With the closing of the door, the door or an additional surface on the door contacts the pin (7) and pushes the pin (7) into the guide (6) with the progression of the closing movement. With the movement of the pin (7) in the guide, the cam arm located in the secondary slot is pushed, and with the force on the cam arm, the cam body performs a rotational movement over the part where it is fixed and transfers the force to the absorber via the first arm (52). The absorber absorbs the force applied thereon, thereby slowing down the movement of the cam body and cam arm, and the cam arm transfers the absorbing movement to the pin. The slowing movement on the pin ensures slow' closing of the door. Thanks to absorbing the load generated during closing of the door, the door is closed without damaging the household appliance.
With the cam body and additional parts formed using the deceleration mechanism (1), more and softer absorption is provided compared to the flat piston structures.
In one embodiment of the invention, the absorber is a damper. In one embodiment of the invention, the absorber is a spring. In one embodiment of the invention, the absorber is a piston. In one embodiment of the invention, the absorber is a hydraulic or a pneumatic device. In one embodiment of the invention, the absorber is a flexible element.
Thanks to the pusher arm (51) passing through the primary slot (61) and the secondary slot (71), the pin (7) transfers the loads thereon to the absorber (4), and in this way, the pin does not lose its position and prevents the deceleration mechanism (1) and cabinet hinge (2) from being damaged due to the fast/harsh closing of the door. In a preferred embodiment of the invention, the bearing cavity (62) made inside the guide (6) is positioned perpendicular to the planar surface of the body (3). Thanks to this positioning of the bearing cavity (62), the pin (7) is also positioned perpendicular to the planar surface, thereby facilitating the damping of the load generated during the closing of the door.
During the closing movement of the door (a→θ), the moments in the closing direction along the angular gap (a→θ) where the slow closing occurs vary with the decrease of the spring force (yk) on the interior of the cabinet hinge (2) and the moment of inertia, of the door depending on the speed of the door. For this reason, the forces to be transferred to the pin (7), cam body (5) and absorber (4) must be nonlinear and adjustable during the closing movement in order to ensure a slow, uninterrupted and linear closing movement. (Figure 5, Figure 6)
In the deceleration mechanism (1) of the invention, the optimization of the forces to be transferred to the absorber (4) during the angular movement (a^0) where slow closing is desired depending on the changes in the spring force (yk) and the door moment of inertia (ak) is provided by the cam forms (i.e. the contact state of the pusher arm (51) and the secondary slot (71 )) operating mutually and transferring load in varying ratios and the cam body (5) operating in connection with the cam forms. (Figure 5, Figure 6)
In the angular position connected by the slow closing movement, the moments in the closing direction (yk+ak) are the highest; the spring force (yk) of the cabinet hinge (2) and the moment of inertia (ak) of the door are high. At this point, the loads to be transferred to the absorber (4) should be at the maximum level and at the same time at the optimum level to ensure the slow closing of the door. In the deceleration mechanism (1 ) of the invention, the sequential cam form (i.e. the contact state of the pusher arm (51) and the secondary slot (71)) and the cam body (5) ensure that the forces transferred to the absorber (4) are at the appropriate level and at the optimum level according to the «ak» and «yk» forces. While the slow closing movement starts comfortably, the excessive loads that may occur on the parts and the risk of deformation due to excessive loads are eliminated by optimizing the forces. (Figure 5)
During the continuation of the closing movement (α→θ), the spring force and the moment of inertia (yk+ak) depending on the speed of the door decreases. Moments in closing direction decrease. During the movement, the cam forms (i.e. the contact state of the pusher arm (51) and the secondary slot (71)) in the deceleration mechanism (1) and the rotating (β) cam body (5) optimize the forces to be transferred to the absorber (4), ensure that the slow closing occurs continuously and linearly, eliminating the noise/comfort problems caused by harsh/fast closing, and the damage to the door, hinge and household appliances. (Figure 7)
At degrees close to full closure (0), the spring force (yk) is minimal, and the angular velocity and moment of inertia (ak) of the door is low. At this point, the moments in the closing direction are at a minimum level. The opposing cam forms (i.e. the contact points of the pusher arm (51) and the secondary slot (71)) and the cam body (5) minimize the forces transferred to the absorber (4), prevent the door from stopping and the closing movement of the door from being interrupted due to the counterforce of the absorber (4). Slow and linear closing movement continues at this point. Full closure is realized with the continuation of the closing movement. (Figure 7)
In one embodiment of the invention, the cam body comprises a central hole to be rotatably fixed to the body (3) or the household appliance, and a second hole on a second arm (52) to be rotatably fixed to the absorber. The cam body can rotate by means of the pin/joint inserted inside these holes.
In one embodiment of the invention, the structure comprised of guide (6) and pin (7) is a piston.
