Description

[0001] The present invention relates to a cooking oven including a swing oven door and a closure system for said swing oven door according to the preamble of claim 1.

[0002] A closure system for a swing door of a household appliance is an important device. If the household appliance is an oven, then the closure system must be heat-resistant in order to guarantee the closing and sealing of the oven door. The most closure systems comprise a hook element and a hook seat element, wherein an opening in the hook seat element receives a hook projecting from the hook element. Usually the hook element is assembled at the door, and the hook seat element is placed at a door frame, front frame or chassis of the household appliance. The hook element sticks out from the oven door, which may disturb the user and impairs the security.

[0003] WO 2007/080146 A2 discloses a closure system comprising the hook seat at the oven frame and the hook at the oven door. However, the mechanism of the hook is complex.

[0004] US 7,735,480 discloses a closure system for two oven doors. The closure system comprises a moveable hook at the oven frame and the hook seat at the oven door.

[0005] It is an object of the present invention to provide a cooking oven including a swing door and a closure system for said swing door, wherein said closure system is improved by low complexity.

[0006] The object of the present invention is achieved by the cooking oven including a swing door and a closure system for said swing door according to claim 1.

[0007] According to the present invention the hook element is attached or attachable at an oven frame of an oven chassis, and the hook seat element is attached or attachable at a door frame of an oven door of the cooking oven. There are not any parts at the oven door, which stick out from the dimensions of said oven door. Thus, the oven door has a very compact structure. In particular, there are not any dangerous elements extending from the oven door. Further, it is easy to clean the oven door.

[0008] Preferably, the hook element is arranged at a vertical part of the oven frame.

[0009] In particular, the hook element is arranged at a position of the vertical part of the oven frame such that the hook seat element is arranged about at half height of the vertical part of the door frame.

[0010] Further, the hook element may be covered by a side wall of the cooking oven, so that the hook element is invisible for a position lateral of the cooking oven in an open state of the oven door.

[0011] According to the preferred embodiment of the present invention the hook seat element is inserted or insertable in a recess of the door frame, so that the hook seat element forms an integrated part of the door frame.

[0012] Advantageously, the shape of the hook seat element is adapted to the shape of the door frame. Thus, the hook seat element can be geometrically and optically adapted to the door frame.

[0013] Further, the door frame and the hook seat element are made of the same plastic materials. This supports the optical adaption of the hook seat element to the door frame.

[0014] For example, the hook seat element is fixed or fixable by one screw at the door frame.

[0015] In a similar way, the hook element is fixed or fixable by at least one screw at the oven frame. In particular, the hook element is fixed or fixable by two screws at the oven frame.

[0016] For example, the hook element is made of metal. Alternatively or additionally, the hook element is made of plastics. Thus, the design of the hook element may be adapted to the design of the cooking oven.

[0017] In order to obtain a vertical centring of the oven door, the shape of the opening and/or the shape of the hook may be formed in such way that an automatic vertical centring of the oven door is performed during closing said oven door.

[0018] Further, the opening and/or the hook may have a conical shape, so that the automatic vertical centring of the oven door is performed during closing said oven door.

[0019] At last, the present invention relates to a closure system for a swing oven door of a cooking oven, wherein the closure system is provided for the cooking oven mentioned above.

[0020] The novel and inventive features believed to be the characteristic of the present invention are set forth in the appended claims.
