[0001] The present invention relates to a cooking oven with an oven cavity and a cooling
channel.
[0002] In a cooking oven food is prepared within an oven cavity. The food is inserted into
and removed from the oven cavity through a front opening. Said front opening is closable
by an oven door. The oven door includes a glass window cooled down by a cooling system.
Said cooling system sucks air from the interior of the oven door. The cooling system
is formed by cooling ducts surrounding the oven cavity. A cooling fan on the top of
the oven cavity circulates air within the cooling ducts.
[0003] During the cooking process steam and vapour in the interior of the oven cavity may
condensate at the glass window of the oven door. In order to avoid the condensation
of steam and vapour at the glass window of the oven door, a system for removing steam
and vapour from the oven cavity is provided. The oven cavity has an aperture connected
to the cooling system. Steam and vapour are sucked through said aperture by the cooling
fan. The aperture is connected to the cooling system via a guiding channel. The guiding
channel and the aperture form a passage for the steam and vapour sucked by the cooling
fan. In order to avoid leakages, a sealing element is required between the guiding
channel and the aperture.
[0004] Usually, the cooling channel is preassembled in a subsidiary station, while the oven
cavity and the cooling channel are fixed to the housing in the main production line.
This require the sealing element ad the correct position of the guiding channel and
the aperture.
[0005] It is an object of the present invention to provide a cooking oven, which allows
an improved sealing between the oven cavity and the cooling channel by low complexity.
[0006] The object is achieved by the cooking oven according to claim 1.
[0007] According to the present invention a cooking oven with an oven cavity and a cooling
channel is provided, wherein:
- the oven cavity includes at least one cavity opening,
- the cooling channel includes at least one guiding channel,
- the cavity opening is connected to the guiding channel,
- the cavity opening is surrounded by a first structure,
- the guiding channel is surrounded by a second structure, and
- the first structure and the second structure are formed complementary to each other.
[0008] The complementary first structure and second structure provide a mechanical sealing
between the cavity opening and the guiding channel. Any further sealing elements are
not required.
[0009] Preferably, the cooling channel is arranged above the oven cavity.
[0010] Further, the oven cavity may be fixed at a housing of the cooking oven.
[0011] In a similar way, the cooling channel may be fixed at the housing of the cooking
oven.
[0012] For example, the oven cavity is fixed at side walls of the cooking oven by screws.
[0013] Similarly, the cooling channel may be fixed at the side walls of the cooking oven
by screws.
[0014] In particular, the first structure is formed rotation-symmetrically in view of the
cavity opening.
[0015] In a similar way, the second structure is formed rotation-symmetrically in view of
the guiding channel.
[0016] For example, the first structure is embossed around the cavity opening.
[0017] Similarly, the second structure may be embossed around the guiding channel.
[0018] Moreover, the oven cavity and the cooling channel are indirectly connected to each
other.
[0019] Preferably, the oven cavity is made of carbon steel. Further, the oven cavity may
be made of stainless steel.
[0020] Preferably, the cooling channel is made of carbon steel. Further, the cooling channel
may be made of stainless steel.
