In modern dishwashers, the door can be positioned at different angles during use. It can be fixed in place, and springs and arms are used to maintain balance during lid movement. Complex mechanisms consisting of carrier brackets are used. Especially the program Finally, the hot and humid air inside is expelled, and the drying performance is improved by 20%. In order to improve it, the covers will automatically adjust to a certain angle at the end of the program. It is desired that the door be opened. For this purpose, a hinge with an automatic door opening function is required. These systems are widely used in the market. Some of the well-known hinge systems with an automatic lid opening function have this 25 Free movement is mostly created by the slot between the carrier bracket and the force-transmitting arm. through guide slots in the shape of a guide and pins that move within these slots This is provided. In these structures, the cover opening angle, slot guide length, and slot are specified. It is extremely sensitive to dimensional parameters such as the gap between the pins. Production Due to deviations arising from tolerances, the cover may not be as free as desired in some cases. It may not reach its opening angle or may get stuck in an intermediate position. Tight tolerance. This requirement increases molding and processing costs, and necessitates additional adjustments during assembly. This also causes wear and tear on the parts rubbing against each other within the slot guide housing over time. Negative aspects such as noise and performance loss can be observed. 35 In conclusion, all the problems mentioned above necessitate an innovation in the relevant technical field. It has made it mandatory. 2 A BRIEF DESCRIPTION OF THE INVENTION The present invention aims to eliminate the aforementioned disadvantages and contribute to the relevant technical field. It is related to a hinge, designed to bring new advantages. 5 One purpose of the invention is to prevent the dishwasher door from coming loose when the program is finished. a hinge structure that allows it to open freely and smoothly within a specific angle range to reveal. Another purpose of the invention is to enable this free opening movement without the need for guide rails with tight tolerances. A hinge that is manufactured and assembled without any noise, with a connection geometry that is easy to use. The goal is to reveal its structure. All the objectives mentioned above and those that will emerge from the detailed explanation below are 15. The present invention aims to achieve this by rotating the lid of dishwashers along an axis of rotation. The dishwasher frame is designed to open and close by rotating. a main body that connects to the fixed frame of the dishwasher, enabling its assembly including a lid connecting arm to which the dishwasher door attaches, lid a closed 20 containing at least one spring that generates force to cause the connecting arm to rotate in the closing direction. It is a hinge that can change position between the ventilation position and the air position. Accordingly, the innovation lies in the fact that the cover connecting handle rotates vertically along the axis while being turned in the opening direction. It will move downwards when the cover connecting lever is rotated in the closing direction. in contact with the main body so that it moves upwards along the vertical axis It includes a carrier plate, connected at one end to a cover connecting arm, and at the other end to a 25 It includes a transmission part that is in contact with the carrier plate, from one end of the carrier plate connected to the transmission part, and connected to the spring at the other end, on the transmission part. It contains a hole, a connecting element extending from the carrier plate into the aforementioned hole. It includes a circular cross-section in the part of the connecting element that fits inside the hole. and the fact that the hole is circular in shape, allows it to open freely from the closed position 30 The diameter of the hole must be such that the connecting element allows for the transition to the ventilation position. its diameter being larger than the circular part of the connecting element remaining inside the hole The ratio of the cross-sectional diameter to the hole diameter should be in the range of 0.8-0.5. Thus, the connection element It operates in a circular form and within a hole with a difference in diameter, with a multi-directional cavity. Slot guide housing structures are simpler to manufacture, less sensitive to tolerances, and have a free 35 a safe opening movement that occurs without the risk of jamming or snagging 3 The connection geometry is obtained.

DETAILED DESCRIPTION OF THE INVENTION 35 This detailed explanation of the invention does not merely aim to improve understanding of the subject matter; it does not contain any other information. This is explained with examples that will not create a limiting effect. 4 Figure 1 shows a representative view of the hinge (10) in the closed position (a1). Given, in Figure 2, a representative view of the hinge (10) in the ventilation position (a2). The hinge (10) attaches the dishwasher door to the frame of the dishwasher. 5. A fastener that can be opened and closed by rotating around its axis of rotation. It serves the function of a hinge (10), a lid connecting handle (12) and a main body. (11) is included. The main body (11) is connected to the fixed frame of the dishwasher. The dishwasher door is mounted on the door connecting handle (12). Hinge (10) allows the cover connecting arm (12) to rotate relative to the main body (11). It provides and thus enables the lid to be opened in the opening direction (I) and closed in the closing direction (II) 10 This makes it possible to close it. The hinge (10) controls the movement of the lid connecting arm (12) and the weight of the lid. It contains at least one spring (14) to balance it. Spring (14) when the lid is closed Support 15 in the closing direction (II) to the cover connecting arm (12) under pre-tension When the lid is moved in the direction of opening (I), the spring (14) is stretched and the lid Continue to move in a controlled manner in the opening direction (I) after a certain angle The publication (14) works on a straight line and its position during the work To prevent it from changing, the spring (14) is kept on a spring holder (15). The spring retainer (15) ensures that the spring (14) remains axially aligned, and the spring (14) 20 by flexing sideways, it prevents them from coming out of their beds and the spring (14) and the main body (11) It provides the link between them. The hinge (10) includes a transfer piece (13) and a carrier plate (20). Transfer part (13) connected at one end to the cover connecting arm (12) and at the other end to the carrier plate 25 It is connected to (20). The carrier plate (20) is connected to the transmission part (13) at one end, and the other end... It is connected to the spring holder (15) at its end. The carrier plate (20) is vertical on the main body (11). The carrier plate moves downwards (-z) and upwards (+z) along the axis (z). (20) this movement depends on the rotational movement of the cover connecting arm (12) This happens. When the lid connecting lever (12) is turned in the opening direction (I), the transfer 30 part (13) carrier plate (20) downwards on the vertical axis (z) relative to the main body (11) (- z) moves. When the lid connecting lever (12) is turned in the closing direction (II) the transfer piece (13) moves the carrier plate (20) upwards (+z) on the vertical axis (z). It causes a connection end on the side where the carrier plate (20) is connected to the spring holder (15). (21) is located. The spring holder (15) is connected to the aforementioned connection end (21). 35 The connecting end (21) is a hook-shaped structure. The spring holder (15) fits into it. Contact of at least one friction wall (111) on the main body (11) on the carrier plate (20). There is at least one friction lug (22) on the carrier plate (20) cover connection. depending on the movement of the arm (12) downwards (-z) and upwards (+z) on the vertical axis (z) While moving, the friction shoe (22) slides along the friction wall (111) This creates a friction force. This friction force causes the lid to open and close. 5 By creating forces in the opposite direction to the motion, the motion becomes more balanced and smoother. It ensures that it happens. In the preferred configuration, on the carrier plate (20) There is a friction lug (22) on each side of the connection area. Main body (11) and on it a friction wall (111) corresponding to each friction shoe (22) is located and thus the carrier plate (20) is balanced on both sides 10 It is supported. The hinge (10) is between a closed position (a1) and a venting position (a2). It can change position. In the closed position (a1), the cover connecting arm (12) of the cover It is positioned so that it completely closes the dishwasher opening and the surface of the door is 15 It is in contact with the front panel of the dishwasher. In the ventilation position (a2) The lid connecting lever (12) is turned in the opening direction (I) and the lid is closed It opens to a limited angle – preferably between 5° and 20° – relative to position (a1). This In this position, the lid separates slightly from the front surface of the dishwasher. The gap between them... The opening allows hot and humid air from inside the dishwasher to escape. It is wide enough to allow, but not to allow the lid to move to the fully open position. It is restricted in such a way as to not allow it to flow. In the ventilation position (a2) the cover itself It remains balanced under its own weight and does so without any additional force applied by the user. It maintains its position. The transfer part (13) is connected to the carrier plate (20) via a connecting element (30). It is connected by the cover connecting arm (12) and a lower connecting element (40). It is connected. The lower connecting element (40) can be a rivet. The transfer piece (13), cover connection so that it can rotate around the lower connecting element (40) It is attached to the arm (12). The connecting element (30) is a first 30 on the horizontal axis (x) and the vertical axis (z). having a circular cross-section with a width equal to diameter (D1) and perpendicular to these two axes It is a structure that extends along the depth axis. The preferred structure is the connecting element (30) attached externally to the carrier plate (20), in the technically known, longitudinal form and It is a circular cross-section fastener (pin, bolt, etc.). In a possible configuration, however... The connecting element (30) can also be a projection that is integral with the carrier plate (20). 35 6 On the transfer piece (13) there is a hole (131) into which the connecting element (30) is placed. It is located. The hole (131) is circular in form with a width equal to a second diameter (D2) value. It is an opening. The first diameter (D1) described above is essentially the hole of the connecting element (30). (131) is the diameter of the circular cross-section part remaining inside. The value of the second diameter (D2) is the diameter of the first diameter. (D1) is greater than the value. In this way, the connection element (30) 5 with hole (131) A gap is formed between them in the circumferential direction (on the horizontal axis (x) and the vertical axis (z)) and The connecting element (30) is inside the hole (131) without constantly contacting the inner surface of the hole (131). It has limited free movement. Essentially, the connecting element (30) remains fixed. The hole (131) is displaced around the connecting element (30). Below is this movement. It is explained in more detail. The horizontal axis (x), vertical axis (z) and 10 mentioned in the specification. The depth axis (perpendicular to the page plane in figures) is a perpendicular axis to each other. When the lid is released from the lock, the lid connecting lever (12) must turn in the opening direction (I). It starts. During this first free opening movement, the transmission part (13) rotates along the axis of rotation. rotating around, hole (131) and the part of the connecting element (30) facing upwards (+z) 15 It has shifted along the vertical axis (z) until it reaches the position where it makes contact. At this stage The carrier plate (20) does not make any movement in the vertical axis (z) and the spring holder (15) Its position is maintained. Thus, the cover is ventilated from the closed position (a1). In a specific angular range corresponding to position (a2), the carrier plate (20) and the spring (14) The mechanism can be opened freely without changing its position. The hole (131) connection 20 After reaching the position on which the element (30) rests, the transfer piece (13) The movement is transmitted directly to the carrier plate (20), the carrier plate (20) on the vertical axis (z) It starts to move. From this point, the spring (14) is stretched and the cover connection The movement of the arm (12) is controlled by the spring (14) force and the friction force. This structure Thanks to this, the lid, once released from the lock, can move freely within a certain angular range. 25 It is doing so by being guided by a controlled force characteristic beyond this angular range. It performs a movement. When the lid is closed, the opposite movement occurs. is happening, hole (131) to the connecting element (30) this time down the connecting element (30) It makes contact from the part facing the (-z) direction. As a result, and in the publication (14) With this force, the carrier plate (20) moves upwards (+z). 30 Circular cross-sectional diameter of the part of the connecting element (30) that remains inside the hole (131) The ratio of the diameter of the hole (131) to the diameter of the lid is in the range of 0.8-0.5. This ratio is such that when the lid comes out of the lock the amount of free opening from the closed position to the ventilation position It determines. The fact that the ratio is within this range means that the connecting element (30) is inside the hole (131) 35 to allow movement with sufficient clearance and to achieve the ideal amount of opening. It provides. During the design phase, the diameters of the hole (131) and the connecting element (30) are two 7 The opening angle and cover in the ventilation position are selected according to the ratio between the elements. The amount of clearance between the front panel and the wall is adjustable. The connecting element (30) is positioned inside a circular hole (131) and Selecting the diameter of the hole (131) so that it is larger than the diameter of the connecting element, 5 Advantages in terms of smooth lid opening movement and ease of production. This structure, which is circular in form and has a difference in diameter, provides the transmission part (13). The hole (131) is freely positioned around the connecting element (30) in different locations. This allows it to be changed. In this way, when the lid is released from the lock... Free opening movement up to ventilation position (a2) wide tolerances 10 It can be obtained both on the horizontal axis (x) and the vertical axis (z) below. Circular The clearance in the hole (131) tolerates deviations resulting from manufacturing and assembly tolerances. able to open freely by clamping the connecting element to the edge of the hole (131). It reduces the risk of hindering its movement. The circular hole (131) structure is a complex slot Mold design is simpler in terms of manufacturing and control compared to their geometries, 15 It also facilitates processing and quality control processes. The scope of protection of the invention is specified in the claims attached hereto, and these details are strictly adhered to. The explanation cannot be limited to those given for illustrative purposes. Because a technically skilled person... The person, without deviating from the main theme of the invention, can create similar 20 based on the above-mentioned points. It is clear that these structures can emerge. 8 REFERENCE NUMBERS GIVEN IN THE FIGURE Hinge 11 Main Body 111 Friction Wall 5 12 Lid Connecting Levers 13 Transmission Parts 131 Holes 14 Springs Spring Holder 10 Carrier Plate 21 Connectors 22 Friction Lugs Connecting Element 40 Lower connecting elements (I) Opening Direction 20 (II) Closing Direction (a1) Closed Position (a2) Ventilation Position D1 First Diameter 25 D2 Second Diameter (x) Horizontal Axis (z) Vertical Axis (+z) Upward Direction (-z) Downward Direction 30
