    FIELD OF THE INVENTION
    [01] The present invention relates to a door opening system for an appliance. For example, said household appliance may be a cooking oven, a dishwasher or a washing machine. BACKGROUND OF THE INVENTION
    [02] In known household appliances, the door is hinged and rotated around a vertical or horizontal axis. If the door is hinged around the vertical axis, then the appliance does not contain any balancing mechanism against the force of gravity. However, if the door is hinged about the horizontal axis, in particular at the lower end of said door, then normally the household appliance comprises the balancing mechanism against the force of gravity.
    [03] In the door hinged around the horizontal axis, at the lower end of the door, a door hinge normally provides a closing force that compresses a door gasket in the closed state of the door. In contrast, in the hinged door around the vertical axis, a door latch normally compresses the door gasket, in the closed state of the door.
    [04] In addition, some well-known household appliances include door locking and unlocking devices. For example, safety interlock devices for pyrolysis oven doors, childproof programmable latches for oven doors and safety latches for washing machines comprise hook mechanisms for locking the door, when the said door should not be opened by a user or child during a potentially dangerous period of an operating cycle. Safety locking and unlocking devices are usually automatically controlled to disengage and release the door when a safe situation exists to open the door.
    [05] In addition, some household appliances, such as drum clothes dryers, comprise a hook mechanism for fitting and locking the door, in which the hook can be detached from the door by a mechanical actuator pressed by the user. Usually, the doors of such household appliances do not contain any door handles.
    [06] A standard pyrolytic door locking system keeps the door closed during the pyrolytic cleaning cycle. The locking mechanism comprises an electric motor, a solenoid or a wax motor to move a mechanical cursor. Said mechanical slider can push a hook into a position, in which said hook fits with the door. The hook is detached from the door when the slider is moved backwards by the electric motor, solenoid or wax motor, respectively, and the hook is pushed back to a passive position. However, closing and opening the door locking system by the above motors takes a relatively long time, for example, about two to five seconds.
    [07] EP 0 632 180 B1 discloses a door opening system for an appliance. Said door opening system comprises a pair of door hinges and a hook mechanism. The door is hinged about a horizontal axis at the lower end of said door. Thus, the pair of door hinges is arranged at the lower end of said door. Substantial components of the door hinges are placed inside the door. In the closed state of the door, said components are arranged vertically inside the door. A small spring 30 pushes a cam 32 and a surface 8 ’’ with a vertical force. Thus, a rapid start of door rotation from the closed to the open state is not possible. In addition, the small spring 30 must be very strong. In addition, the positions of the rotation axes 5 and 25 contribute to the rapid start of rotation of the door is not possible. The hook mechanism is arranged at an upper end of the door. Hook 21 can be fitted with the door frame covered by the door. The opening of the door is caused by the release of the hook mechanism. In order to open the door, the user has to press a button 21 'on an upper front portion of said door. When pressing the button 21 ', the hook 21 is lifted from its locked position, so that the door can be opened by a roller 31 pressed by the small spring 30. However, at the same time, the user also pushes the portion of upper end of the door to its closed position, when pressing the button 21 '. Thus, the effective opening of the door depends on a sufficient inertia of the hook 21 and / or a sufficiently short operation of the button 21 '. In addition, the hook mechanism is operated manually, while electrical operation is not possible. Such an electrical operation would require wiring and a power supply for the door. Finally, the door hinges and the hook mechanism have complex structures. DESCRIPTION OF THE INVENTION
    [08] It is an object of the present invention to provide a door opening system for an appliance, which allows a simple opening and closing of the door with low complexity.
    [09] The object of the present invention is achieved by the door opening system according to claim 1.

    [011] The main idea of the present invention is that the substantial components of the door hinge are placed on the support structure of the appliance, but not on the door. The stationary part of the hinge 18 is arranged horizontally and the first and second spring elements generate horizontal forces. The second spring element allows a horizontal opening force and a very low spring force, so that the start of rotation of the door is very fast. In addition, the arrangement of the door hinge allows the pivot axis to be close to the appliance and therefore the door can be rotated very quickly.
    [012] A roller can be arranged on one end of the second spring element, the end of which contacts the door or a part that is rigidly connected to said door.
    [013] Preferably, the door opening system comprises a pair of door hinges that have a common pivot axis.
    [014] In particular, the hook mechanism and the hook element are arranged in a chassis of the household appliance, while the recess is formed in the door. Alternatively, the hook mechanism and the hook element can be arranged on the door, while the recess can be formed on the chassis of the household appliance.
    [015] In addition, the hook mechanism includes a hook spring element that pushes the hook element into the position, in which the recess is arranged, if the door is in the closed state. The hook spring element supports the hook mechanism of the hook element and the recess.
    [016] For example, in the partially open state of the door, an opening angle between the door and a front frame of the appliance is between 10 ° and 30 °, preferably about 20 °.
    [017] In addition, in the fully open state of the door, the opening angle between the door and the front frame of the appliance is between 80 ° and 90 °, preferably about 85 °.
    [018] In addition, the door hinge may include a friction element between a stationary part of the hinge and an articulated hinge part of said door hinge, wherein said friction element stops the door at a predetermined angle of opening. When the hook element is released from the recess, then the door is automatically opened and stopped at the predetermined opening angle.
    [019] Preferably, the friction element is made of plastic.
    [020] In addition, the first spring element can keep the door balanced against the force of gravity within the angled opening range of said door.
    [021] Alternatively or in addition, the first spring element can keep the door balanced against the force of the second spring element within the angular opening range of said door.
    [022] Preferably, the door is kept closed by the hook element fitted with the recess.
    [023] In particular, the door is kept closed only by the hook element fitted in the recess and without any force from the first spring element and the second spring element.
    [024] For example, the door is hinged around a horizontal axis.
    [025] In addition, the door can be hinged around a vertical axis.
    [026] Finally, the present invention relates to an appliance, including at least one door, wherein the appliance comprises a door opening system mentioned above.
    [027] New and inventive features of the present invention are presented in the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF ACCOMPLISHMENTS OF THE INVENTION
    [029] FIG 1 illustrates a schematic cross-sectional side view of an appliance 10 which includes a door opening system according to a preferred embodiment of the present invention, wherein a door 12 is in a closed state. In this embodiment, the door 12 is hinged about a horizontal axis at the lower end of said door 12. For example, the appliance 10 is a cooking oven and the door 12 is an oven door.
    [030] The appliance door opening system 10 includes a door hinge 14 and a hook mechanism 16. The door hinge 14 establishes the hinged connection between the lower portions of the appliance 10 and door 12. The mechanism hook 16 establishes a snap connection between the upper portions of the appliance 10 and the door 12. The hook mechanism 16 is arranged on the appliance 10.
    [031] The hinge of the door 14 includes a stationary part of the hinge 18 and a hinge part of the hinge 20. The hinge part of the hinge 20 forms a hinge arm. The hinge hinge part 20 is rotatably connected to the hinge stationary part 18 on a first hinge axis 21. In addition, the hinge hinge part 20 is rotatably connected to a first stem 23 on a second hinge axis 27. The hinge part 20 stationary hinge 18 is arranged in and / or in the appliance 10, while the hinge part 20 is arranged in and / or next to the door 12. In addition, the door hinge 14 includes a first spring element 22 and a second spring element 24. In this example, the first spring element 22 and the second spring element 24 are helical compression springs.
    [032] The hook mechanism 16 includes a hook element 26. The hook element 26 is hinged on the hook mechanism 16. The hook element 26 can be fitted with a recess 28 formed in and / or next to the door 12. In this example, the recess 28 is formed on an upper circumferential side of the door 12. When the hook element 26 is engaged in the recess 28, then the door 12 is locked. The hook mechanism 16 can be triggered mechanically or electromechanically, in order to disengage the hook element 26 from the recess 28 and to release the door 12. In this way, the hook mechanism 16 can be controlled manually by the user or automatically. For example, the hook element 26 can be detached from the recess 28 by pressing a button. If the hook element 26 is visible, then the door 12 can be opened manually. In addition, the hook element 26 can be detached from the recess 28 electromechanically, for example by an electric motor, a solenoid or a wax motor.
    [033] In particular, the hook mechanism 16 has a safety lock on the door 12 in potentially dangerous situations. For example, during a pyrolytic cleaning cycle in an oven, door 12 must be locked as a precaution. In addition, oven door 12 can provide programmable child safety locks. In addition, the door 12 of a washing machine can provide a security lock. In general, the hook mechanism 16 of the inventive door opening system allows door 12 of the appliance 10 to be opened in all situations, in which door 12 must be opened, through the operation of a control element. The operation of said control element disengages the hook element 26 from the recess 28. The door 12 does not require a handle.
    [034] The hinge of the door 14 provides an unbalanced movement of the door 12 within an angular opening range of said door 12. In contrast, the hinge of the door 14 provides a balanced movement of the door 12 within an angular opening range. exterior of said door 12. The interior opening angle of door 12 extends from the closed state to a partially open state of said door 12. The exterior opening angle of door 12 extends from the partially open state to the fully open state of said door 12. The hinge of door 14 can be provided for a door 12, hinged about a horizontal axis, as well as a vertical axis.
    [035] Within the interior opening angular range, the movement of the door 12 is unbalanced against the force of gravity and / or the force of the second spring element 24 pushes and opens said door 12. In contrast, within the angular range of exterior opening, the movement of the door 12 is at least substantially balanced against the force of gravity and / or against the force of the spring element that pushes and opens said door 12. Thus, the door hinge 14 allows rapid movement of the door 12 within the inner opening angle range, after the door 12 has been released by the hook mechanism 16. Then, within the outer opening angle range, the movement of the door 12 is postponed by the balancing force of the hinge of the door. port 14 by means of the first spring element 22.
    [036] The substantial components of the door hinge 14 are placed in the support structure of the appliance 10, but not in the door 12. Thus, the stationary part 18 of the hinge, the first spring element 22 and the second spring element 24 are laid out horizontally. The second spring element 24 allows a horizontal opening force and a very low spring force. The rotation of door 12 starts very quickly. In addition, such positioning of the door hinge 14 allows advantageous positions of the first pivot axis 21 and second pivot axis 27, which are in the vicinity of the appliance 10 and therefore the door 12 can be rotated very quickly.
    [037] FIG 2 illustrates a schematic side sectional view of the appliance 10 which includes the door opening system according to the preferred embodiment of the present invention, where the door 12 is in a partially open state.
    [038] FIG 2 shows the same appliance 10 as FIG 1, in which the door 12 is tilted and partially open. An opening angle 34 is formed between the inside of the sloped door 12 and the plane of a front frame 32. In this example, the opening angle 34 is about 20 °. In a completely open state, the opening angle of door 12 is about 85 °. A gasket 30 is attached to the front frame 32 of the appliance 10. In the closed state of the door 12, the gasket is compressed between the front frame 32 and said door 12, as shown in FIG 1.
    [039] FIG 3 illustrates a schematic side sectional view of a door hinge 14 of the door opening system according to the preferred embodiment of the present invention, where the door 12 is in the partially open state.
    [040] FIG 3 shows in detail the hinge of the door 14, which includes the stationary hinge part 18, the hinge part of the hinge 20, the first spring element 22 and the second spring element 24. In addition, FIG 3 shows in detail the gasket 30 attached to the front frame 32 of the appliance 10.
    [041] The second spring element 24 provides an opening force for the door 12. Said opening force pushes the door 12 to the partially open state. In order to open the door 12 by a low spring force, a profile of part of the hinge to come into contact with a hinge roller is designed in such a way that the second spring element 24 does not provide any closing force when the port 12 is in the closed state. The door 12 is kept closed only by the hook mechanism 16.
    [042] The first spring element 22 mediates the partially open state of door 12. In addition, the first spring element 22 keeps the door 12 balanced within the angular opening range of said door 12. In addition, the first element spring 22 defines the opening angle of the door 12.
    [043] The hinged part of the hinge 20 includes a cam 25. A sliding rod 31 with a roller at its end is connected to the second spring element 24. The second spring element 24 provides the opening force for the door 12. A said opening force pushes the door 12 to the partially open state. The arrangement of the second spring element 24, the sliding rod 31 with the roller and the cam 25 allows the horizontal opening force and the spring force to be very low, in which the start of rotation of the door 12 is very fast.
    [044] Alternatively, the door hinge 14 may include a single spring element, instead of the first spring element 22 and the second spring element 24. In this case, said single spring element provides the opening force inside the angular range of inner opening and the equilibrium force within the angular range of outer opening.
    [045] In addition, if the door 12 has to be stopped at an exact opening angle, for example, the opening angle 34 of the partially open state, then a friction element can be disposed between the stationary part of the hinge 18 and the hinged part of the hinge 20. For example, the friction element is made of plastic.
    [046] FIG 4 illustrates a schematic side sectional view of the door hinge 14 of the door opening system according to the preferred embodiment of the present invention, where the door 12 is in the closed state.
    [047] FIG 4 shows in detail the stationary part of the hinge 18, the hinge part of the hinge 20, the first spring element 22 and the second spring element 24 of the door hinge 14. In addition, FIG 4 illustrates the gasket 30 compressed between the front frame 32 of the appliance 10 and the door 12.
    [048] FIG 5 illustrates a schematic cross-sectional side view of the hook mechanism 16 of the door opening system according to the preferred embodiment of the present invention, where the door 12 is in the closed state.
    [049] The hook mechanism 16 includes the hook element 26. Said hook element 26 is fitted or can be fitted into the recess 28 formed in the door 12. Furthermore, the hook mechanism 16 includes a spring-loaded element. hook 36. Said hook spring element 36 causes the hook element 26 to be pushed down in the example of FIG 5. In general, the hook spring element 36 causes the hook element 26 to be pushed towards the position, in which the recess 28 of the door 12 is arranged, when the door 12 is in the closed state. Thus, the hook element 26 and the recess 28 form a locking mechanism. The door 12 can be closed manually by the user and is automatically blocked by the hook element 26.
    [050] The hook mechanism 16 of the door opening system can be controlled manually by the user or automatically. For example, the hook element 26 is detached from the recess 28 by pressing a button. If the hook element 26 is visible, then the door 12 can be opened manually. In addition, the hook element 26 can be detached from the recess 28 electromechanically, for example by an electric motor, a solenoid or a wax motor.
    [051] FIG 6 illustrates a schematic side view in more detailed section of the door hinge 14 of the door opening system according to the first embodiment of the present invention, where the door 12 is in the closed state. FIG 3 shows the hinge of the door 14, which includes the stationary part of the hinge 18, the hinge part of the hinge 20, the first spring element 22 and the second spring element 24.
    [052] In addition, the hinged hinge part 20 includes cam 25. The sliding rod 31 with the roller at its end is connected to the second spring element 24. The second spring element 24 provides the opening force for door 12. Said opening force pushes door 12 to the partially open state. The second spring element 24 pushes the sliding rod 31 with the roller at its end against the cam 25 of the hinge hinge part 20. The second spring element 24 with the sliding rod 31 and the roller pushes the hinge part 20 with the cam 25 to the partially open position, until the second spring element 24 is decompressed. When the door 12 is closed, then the hinge part 20 with the cam 25 pre-compresses the second spring element 24. In FIG 6, the second spring element 24 is in the pre-compressed state. The hinged part of the hinge 20 with the cam 25 is designed in such a way that the second spring element 24 does not provide any closing force when the door 12 is in the closed state. The door 12 is kept closed only by the hook mechanism 16.
    [053] The first rod 23 is disposed within the stationary part of the hinge 18. A second rod 29 is connected in series to the first rod 23. The first rod 23 and the second rod 29 extend along a substantially horizontal direction. The first spring element 22 surrounds the second stem 29. In FIG 6, the first spring element 22 is in an uncompressed state.
    [054] FIG 7 illustrates a schematic side view in more detailed section of a door hinge 14 of the door opening system according to the first embodiment of the present invention, where the door 12 is in the partially open state.
    [055] Due to the partially open state of the door 12, the first stem 23 and the second stem 29 are pulled by the hinged part of the hinge 20, so that the first spring element 22 is in a pre-compressed state. The pre-compressed state of the first spring element 22 keeps the door 12 balanced within the outer opening angular range of said door 12. In said outer opening angular range, the opening angle of the door 12 is greater than in the partially opened state. open.
    [056] FIG 8 illustrates a schematic side view in section of the household appliance that includes the door opening system according to a second embodiment of the present invention, in which the door is in a partially open state.
    [057] The door opening system according to the second mode differs from the first mode in that the door hinge 14 requires only one spring element, that is, the first spring element 22. The second spring element 24 is formed as a separate part in the second embodiment. In FIG 8, the second spring element 24 is arranged on a flange or frame of the door that delimits the cavity of the oven. Alternatively, the second spring element 24 can be arranged on the door 12. The second spring element 24 pushes the door 12 into its partially open state. In FIG 8, the second spring element 24 is in an uncompressed state.
    [058] In addition, a pylon 33 is disposed at the end of the second spring element 24, which can come into contact with the port 12, or the flange, respectively. Preferably, pestle 33 is made of plastic.
    [059] FIG 9 illustrates a schematic side view in section of an appliance that includes a door opening system according to the second embodiment of the present invention, in which a door is in a closed state.
    [060] The hook element 26 is fitted into the recess 28, so that the door 12 is blocked. In FIG 9, the second spring element 24 is in a pre-compressed state.
    [061] An application of the door opening system is a pyrolytic door locking system. Said pyrolytic door locking system ensures that door 12 is kept closed during the pyrolytic cleaning cycle. Door 12 can be closed manually by the user. Then, the hook element 26 engages the recess 28 automatically by the force of the hook spring element 36. The time to lock the door 12 is less than 0.2 seconds.
    [062] Another application of the door opening system is a child safety locking system, which prevents door 12 from opening when a force acts on door 12 along the opening direction.
    [063] The door opening system according to the present invention allows the appliance 10 to include a door 12, without any door handle. The door opening system allows very quick opening of door 12. Door 12 can be opened manually, by lifting the hook element 26, by the user or automatically by operating a push button or touch sensor to activate the hook element 26 The door hinge 14 or door hinges 14 can be realized with low complexity. Door 12 can be stopped at each angle within the outer opening angular range. No additional damping elements are needed.
    [064] Although an illustrative embodiment of the present invention has been described herein with reference to the attached drawing, it should be understood that the present invention is not limited to that precise embodiment, and that various other changes and modifications may be made to it by a person skilled in the art. art without departing from the scope or spirit of the invention. All such changes and modifications are intended to be included in the scope of the invention as defined by the appended claims.
