Description
[0001] This invention relates to a cooking oven chamber.
[0002] DE 102 41 487 A1, whose content is hereby referred to in its
entirety, describes a cooking oven chamber with one or several
shelf supports that are positioned in one or several planes and
[0003] are designed to accept one or several removable and
interchangeable food carriers at one or several levels in the area
facing the chamber back panel, and [0004] permit, on and/or by
means of a first set of guides positioned on mutually opposite wall
panels and/or on the roof panel and/or on the bottom of the
cooking-oven chamber, essentially horizontal movement between a
rearward position in which the food carriers are in the cooking
zone and a forward position in which the food carriers are in the
loading/unloading zone.
[0005] That cooking-oven chamber offers advantages when designed
for accessibility from both sides. One-sided accessibility,
however, for instance in a corner, tends to obstruct removal of the
food carriers. Moreover, that type of oven chamber is complex,
resulting in high costs and low energy efficiency.
[0006] It is therefore the objective of this invention to reduce
that complexity while improving user friendliness in the
interchanging process.
[0007] According to the invention, that objective is achieved with
the features per claim 1. Enhanced configurations are described in
the sub-claims.
[0008] The cooking-oven chamber includes at least one cooking
level, two mutually opposite side walls and at least one pull-out
system mounted on a first side wall for guiding at least one
retaining device, serving to hold at least one food carrier in
place, between a cooking position of that minimum of one food
carrier inside the oven chamber and a servicing position in which
said minimum of one food carrier is partly or completely outside
the oven chamber.
[0009] This permits convenient removal of the food carriers even if
the oven chamber is not accessible from two sides. The user does
not stand in front of the oven chamber but to the side of it.
[0010] The minimum of one food carrier can be held by the minimum
of one retaining device, from a first side and especially
(cantilevered) in a lateral section facing the first side wall. In
the servicing position of the minimum of one retaining device the
food carrier can be set on or slid, hung, plugged or latched into
that minimum of one retaining device, or removed from it, in
particular from an opposite, second side.
[0011] The lateral region of the minimum of one food carrier that
serves as its retaining section specifically makes up a maximum of
one third, specifically a maximum of one fourth or specifically a
maximum of one fifth of the extension of the minimum of one food
carrier in its axial direction [sic]. Specifically, it encompasses
a bottom section and/or a circumferential rim section of the food
carrier, with the retaining rim area specifically encompassing a
section that extends in a parallel and/or normal pull-out direction
of the preferably circumferential rim.
[0012] The minimum of one retaining device is preferably provided
with first contoured elements that interact with second contoured
elements of the minimum of one food carrier, in a manner as to
secure the latter in its position.
[0013] A single cooking level can accept a single retaining device
that is individually guided and can hold one food carrier. For a
group of cooking levels one common retaining device can be
employed, permitting individually guided movement and capable of
holding one food carrier per cooking level. A group may encompass
all or some of the (available) cooking levels.
[0014] The minimum of one retaining device specifically consists of
a pair of holders, positioned parallel to and at a distance from
each other in the pull-out direction, with the minimum of one
pull-out system preferably consisting of a pair of extending slides
positioned parallel to and at a distance from each other
perpendicular to the pull-out direction.
[0015] The minimum of one pull-out system is preferably designed as
a telescoping pull-out mechanism.
[0016] The invention also relates to a cooking oven incorporating
at least one oven chamber as described above.
[0017] The following will explain the concept of this invention in
more detail with the aid of an implementation example and with
reference to the diagrams in which:
[0018] FIG. 1 depicts an oven chamber according to the invention,
with an oblique front view of a retracted food carrier and the
extending slides;
[0019] FIG. 2 is an oblique top view of the outside of the
extending slides;
[0020] FIG. 3 is a partial illustration of the food-carrier
locating system;
[0021] FIG. 4 is a front view of the oven chamber;
[0022] FIG. 5 is a top view of the retracted food carrier.
[0023] The oven chamber 2 features a chamber enclosure 4, a
pull-out system 6 and a retaining device 8 supporting the food
carriers 10, 12.
[0024] The oven chamber 4 consists of mutually parallel side walls
14, 16, a bottom panel 18, a top panel 20, a back wall 22 and a
loading port 24.
[0025] The pull-out system 6 includes two dual extending slides 26
with fixed tracks 28 that accept moving tracks 30 which on their
part guide moving tracks 32. The fixed tracks 28 are positioned,
spaced vertically one above the other, on the side wall 16 and
extend in an at least essentially horizontal direction.
[0026] The retaining device 8 consists of two holding bars 34
which, at a horizontal distance from each other, are respectively
mounted on the two outer moving tracks 32 and feature, one above
the other, food carrier seats 36.
[0027] The food carrier 10 is a broiling grill, the food carrier 12
is a grease drip pan.
[0028] The food carrier seat 36 is in the form of a slot that can
accept the broiling grill 10, which latter is thus supported on the
bottom by a lower section 38 of the slot 36 while its top is braced
against a bracket 40 laterally extending from the slot 36. The
lower section 38 of the slot 36 is formed on the top side of a tab
42 that points in the direction of the broiling grill 10 and from
whose bottom side the bracket 40 extends away from the oven chamber
2. Further in the direction of the broiling grill 10 the top
surfaces of the tabs 42 are provided with recesses 44 that accept
the laterally crimped sections 46 of lattice rods 48 which delimit
the perimeter of the broiling grill 10. The positive seating of the
sections 46 in the recesses 44 locks the broiling grill 10 in place
in both horizontal axial directions.
[0029] Located underneath the food carrier seats 36 for the
broiling grill 10 are additional food carrier seats 36 for the
placement of the grease drip pan 12. Here, the function performed
by the circumferential lattice rod 48 in the case of the broiling
grill 10 is performed by the circumferential rim 50 of the grease
drip pan 12.
[0030] The mode of operation is as follows:
[0031] When a user wants to insert a broiling grill 10 in the oven
chamber 2, he will first grab the front holding bar 34 in order to
pull it, along with the tracks 30 and 32, out of the loading port
24 far enough to also bring the rear holding bar 34 to the front of
the loading port.
[0032] He then holds the broiling grill 10 at the two sides that
extend parallel to the back wall and pushes it into the slots 36 in
the normal withdrawal direction until it butts against the holding
bar 34, whereby the circumferential lattice rod 48 braces itself
downward against the sections 38 of the lower tabs 42 and upward
against the brackets 40 of the upper tabs 42, with the crimped
sections of the lattice rod 48 engaged in the recesses 44 of the
tabs 42.
[0033] In so doing the user is not standing in front of the oven
chamber but to the side of it. Nor does he look into the oven
chamber but perhaps at a kitchen wall which in this case may be
located directly behind the opposite side wall of the oven chamber
and thus directly behind the pulled-out extending slides without
interfering with the loading process.
[0034] The broiling grill thus locked in position is now pushed
into the oven chamber 2 so that, after the door, not illustrated,
of the loading port 24 is closed, the cooking process can be
initiated.
[0035] The one-sided manipulation (on the right or left side wall
of the oven chamber) permits more convenient handling when
interchanging food carriers in the oven chamber. By the same token,
it can be operated by handicapped persons, permitting convenient
loading and unloading of the food carriers for instance from a
wheelchair. Compared to two-sided operation (on the right as well
as the left side wall of the oven chamber), it is less expensive to
make and, having fewer metal parts, it offers greater energy
efficiency.
[0036] The extending slides may be firmly mounted on a support
structure that can be inserted, first at an angle of about 45
degrees, in the upper area of the oven chamber 2 for instance in
two perforations and then tilted down to be locked in place in the
lower area for instance with a knurled knob. All this can be done
on the right or on the left wall of the oven chamber depending on
the user's preference. In the same manner in which the food
carriers permit positive connection to the holding bars, the
holding bars can be connected in positive fashion to the
tracks.
[0037] In embodiments not illustrated, it is also possible to
provide for each cooking level a lateral extending slide or a
lateral pair of extending slides with one or several food carrier
seats, each for a single food carrier, in which case all extending
slides are positioned on one side, permitting individually
independent shifting between a cooking position and a servicing
position.
