Description
PRIORITY CLAIM
[0001] This application claims the benefit of priority of U.S.
Provisional Patent Application No. 61/558,726, filed Nov. 11, 2011,
which is incorporated herein by reference for all purposes.
FIELD OF THE INVENTION
[0002] The subject matter of the present disclosure relates
generally to a rack mounting system for an oven appliance.
BACKGROUND OF THE INVENTION
[0003] Conventional oven appliances are typically equipped with one
or more racks located in the cooking chamber of the appliance. The
interior walls of the oven cavity are provided with grooves into
which the racks are received. The racks can slide back and forth on
these grooves. Additionally, grooves at multiple levels may be
provided so that a user of the appliance can adjust the height to
accommodate utensils of various sizes and/or determine the distance
between the utensil and one or more heating elements used for
cooking food in the utensil.
[0004] Movement of the racks within the grooves depends on a
sliding movement by the rack across a surface of the interior wall
that forms the oven cavity and defines the grooves. Thus, the
amount of friction between the rack and this surface determines the
level of difficulty a user may have in withdrawing or inserting the
rack from the oven cavity. The rack and/or interior surface may be
provided with coatings that provide protection or other desirable
properties within the extreme temperatures of the oven cavity.
However, these coatings may also increase the amount of friction
encountered in sliding the racks in and out of the oven, requiring
additional effort by a user attempting to move the racks.
[0005] Additionally, the grooves of the oven rack may be provided
with one or more features for limiting the sliding movement of the
rack and/or prevent tilting of the rack when it is extended from
the oven. The guides may include, for example, features that limit
the amount by which the oven rack can be slid into or out of the
oven. Some users may prefer to slide a rack out of the oven while
leaving the cooking utensil in place on the rack. However,
depending on the size of utensil and the guide's limit on how far
the rack can be slid out of the oven cavity, this procedure may not
provide enough room to e.g., view the interior of the cooking
utensil and/or remove a top from the utensil. Also, the removal of
the rack can be cumbersome due the shape of the guides and or
positioning of the features that limit the overall movement and/or
tiling of the rack.
[0006] Accordingly, an oven appliance having one or more racks for
holding cooking utensils and/or food during the cooking process
would be useful. More particularly, an oven appliance having one or
more racks that can be extended, without undesirable tilting, from
the interior of the oven cavity in order to improve access to the
rack would be beneficial. An oven rack that can reduce the friction
or effort to insert or withdraw the rack from the cavity would also
be useful. An oven rack system that can employ multiple racks that
are readily removable and/or positionable within the oven cavity
would be particularly beneficial.

DETAILED DESCRIPTION OF THE INVENTION
[0017] The present invention provides an extendable oven rack
mounting system for an oven appliance. The racks can be readily
withdrawn, or inserted into, a cavity of the oven appliance. One or
more features are provided that can be used for securing rack
assemblies within the oven cavity during use including features
that can prevent tilting and horizontal displacement of the rack
assembly. Height adjustability of the racks can also be provided.
Reference now will be made in detail to embodiments of the
invention, one or more examples of which are illustrated in the
drawings. Each example is provided by way of explanation of the
invention, not limitation of the invention. In fact, it will be
apparent to those skilled in the art that various modifications and
variations can be made in the present invention without departing
from the scope or spirit of the invention. For instance, features
illustrated or described as part of one embodiment can be used with
another embodiment to yield a still further embodiment. Thus, it is
intended that the present invention covers such modifications and
variations as come within the scope of the appended claims and
their equivalents.
[0018] Referring to FIG. 1, an exemplary embodiment of an oven 100
according to the present invention is shown. FIG. 1 provides a
front view of oven 100 while FIG. 2 provides a partial perspective
view into the cooking chamber or cavity 116 into which an oven rack
and support system 117 has been installed. Cooking chamber 116 is
defined by interior walls including opposing side walls 118, bottom
wall 119, and top wall 121. Multiple oven racks 132 are positioned
within cavity 116, the support of which will be further
described.
[0019] Oven 100 includes a door 104 with handle 106 that provides
for opening and closing access to a cooking chamber 116. A user of
the appliance 100 can place a variety of different items to be
cooked in chamber 116. Cooking chamber 116 is equipped with an
extendable rack mounting system 117 for racks 132 as will be
further described herein. One or more heating elements (not shown)
can be positioned e.g., at the top of chamber 116 to provide heat
for cooking and cleaning Such heating element(s) can be e.g., gas,
electric, microwave, or a combination thereof. Other heating
elements could be located at the bottom of chamber 116 as well. A
window 110 on door 104 allows the user to view e.g., food items
during the cooking process. For purposes of cooling, vent 108
allows for an inflow of ambient air into a ventilation system while
vent 134 allows for the outflow of such air after it has been
heated by oven 100.
[0020] Oven 100 includes a user interface 102 having a display 103
positioned on top panel 114 with a variety of controls 112.
Interface 102 allows the user to select various options for the
operation of oven 100 including e.g., temperature, time, and/or
various cooking and cleaning cycles. Operation of oven appliance
100 can be regulated by a controller (not shown) that is
operatively coupled i.e., in communication with, user interface
panel 102, heating element(s), and other components of oven 100 as
will be further described.
[0021] For example, in response to user manipulation of the user
interface panel 102, the controller can operate heating element(s).
The controller can receive measurements from a temperature sensor
(not shown) placed in cooking chamber 116 and e.g., provide a
temperature indication to the user with display 103. By way of
example, the controller may include a memory and one or more
processing devices such as microprocessors, CPUs or the like, such
as general or special purpose microprocessors operable to execute
programming instructions or micro-control code associated with
operation of appliance 100. The memory may represent random access
memory such as DRAM, or read only memory such as ROM or FLASH. In
one embodiment, the processor executes programming instructions
stored in memory. The memory may be a separate component from the
processor or may be included onboard within the processor.
[0022] The controller may be positioned in a variety of locations
throughout appliance 100. In the illustrated embodiment, the
controller may be located under or next to the user interface 102
or otherwise within top panel 114. In such an embodiment,
input/output ("I/O") signals are routed between the controller and
various operational components of appliance 100 such as heating
element(s), controls 112, display 103, sensor(s), alarms, and/or
other components as may be provided. In one embodiment, the user
interface panel 102 may represent a general purpose I/O ("GPIO")
device or functional block.
[0023] Although shown with touch type controls 112, it should be
understood that controls 112 and the configuration of appliance 100
shown in FIG. 1 is provided by way of example only. More
specifically, user interface 102 may include various input
components, such as one or more of a variety of electrical,
mechanical or electro-mechanical input devices including rotary
dials, push buttons, and touch pads. The user interface 102 may
include other display components, such as a digital or analog
display device designed to provide operational feedback to a user.
The user interface 102 may be in communication with the controller
via one or more signal lines or shared communication busses. Also,
oven 100 is shown as a wall oven but the present invention could
also be used with other appliances such as e.g., a stand-alone
oven, an oven with a stove-top, and other configurations as
well.
[0024] Referring now to FIGS. 2, 3 and 4, front view and side views
of an exemplary embodiment of a frame or ladder 120 as may be used
to support one or more oven racks 132 according to the present
invention are illustrated. A perspective view of frame 120 is shown
in FIG. 5. Frame 120 includes a plurality of horizontal supports
122 that extend from vertical supports 124. As shown in FIG. 2 and
FIG. 4, horizontal supports 122 extend away from vertical supports
124 and into oven cavity 116. Each vertical support 124 has two
tabs 126, one each positioned near the top 143 and bottom 145 of
vertical support 124. Tabs 126 each include an aperture 127 (FIG.
3) for attachment using a fastener to a respective side wall 118 of
oven 100. For this exemplary embodiment, a pair of frames 120 is
mounted within cavity 116--one each along the opposing side walls
118. As will be further described, horizontal supports 122 can be
used to provide support for an extendable rack. For the exemplary
embodiment shown in the figures, five racks can be supported at
five different levels within cavity 116. The levels are provided by
opposing horizontal supports 122--one each extending from a frame
120 positioned on opposing sides walls 118.
[0025] Frame 120 is provided by way of example, and other
configurations may be used as well. For example, a different number
of horizontal supports 122 may be employed for more or less racks
as desired. Frame 120 can be constructed from elongated wire
members that are welded together as shown. One or more coatings may
also be applied to protect frame 120 from the extreme temperature
conditions that can be encountered in oven 100. Other materials may
also be used to construct frame 120.
[0026] FIG. 6 is an exploded perspective view of an exemplary
embodiment of an oven rack assembly 128, one or more of which may
be used with the oven of FIGS. 1 and 2. As shown, oven rack
assembly 128 includes rack 132, a pair of slide assemblies (further
described below), and under-rack 144. For this exemplary
embodiment, rack assembly 132 is constructed from elongated rods
133 that are joined together to provide a shelf or baking surface
for the receipt of food items and/or cooking utensils. As with
frame 120, the elongated rods may be coated with one or more
materials for e.g., protection from oven temperatures and easier
cleaning
[0027] Rack 132 includes a handle 146 for use in inserting or
removing rack 132 from chamber 116. Loops 148 and 150 can serve to
prevent items from sliding off the back of rack 132 and as
additional handles for rack 132. The shape and configuration of
rack 132 as shown in FIG. 6 is exemplary only--other configurations
may be used as well including e.g., different materials for the
construction of the rack 132 other than elongated rods 133.
[0028] As stated, each opposing side 165 and 167 of rack 132 is
attached to a slide assembly that, for this exemplary embodiment,
includes an inner bracket (152 or 154), slide (136 or 138), and
outer bracket (140 or 142). More specifically, each rack 132 is
connected as shown in FIG. 6 to inner brackets 152 and 154. In
turn, inner brackets 152 and 154 are attached to slides 136 and 138
on opposing sides 165 and 167 of rack 132, respectively. Slides 136
and 138 are attached to outer brackets 140 and 142,
respectively.
[0029] The construction of slides 136 and 138 facilitates the
insertion, extension, and removal of rack 132 from cavity 116 with
less effort than conventional designs where a rack slides on a
surface of the oven wall. For example, slides 136 and 138 can be
configured with one or more ball bearings to reduce friction from
sliding movement. Slides 136 and 138 can also allow for a full
extension of rack 132 from cavity 116 for more complete access to
food and/or utensils placed on rack 132.
[0030] Slides 136 and 138 are attached to an under-rack 144. More
particularly, slide 136 is attached to outer bracket 140 while
slide 138 is attached to outer bracket 142. Outer brackets 140 and
142 are connected to under-rack 144. Under-rack 144 is constructed
from parallel elongated members 156 and a support 157 that extends
within elongated members 156 as shown.
[0031] Rack assembly 128 can be placed onto the opposing pair of
frames 120 that are attached to opposing walls 118 within oven
chamber 116. In such position, each bracket 140 and 142 is placed
onto a horizontal support 122 within cavity 116 of oven 100. As
desired by a user, multiple rack assemblies 128 can be placed on,
and supported by, horizontal supports 122 as shown in FIG. 9. A
user could, for example, use a rack assembly on each level provided
by horizontal supports 122 as illustrated. Alternatively, the user
can select just one of the levels provided by a pair of opposing
horizontal supports 122 as desired for cooking The user could then
place a rack assembly 128 at such level and remove one or all of
rack assemblies from any of the other levels.
[0032] Returning to FIG. 6, locking tabs 158 and 160 extend
downwardly from front portions of outer brackets 140 and 142 as
shown in FIG. 6. As such, tabs 158 and 160 can make contact with
the curved end portions 123 (FIGS. 3 and 5) of horizontal supports
122 (see FIGS. 3 and 9) to limit horizontal displacement of a
respective oven rack assembly 128. More specifically, tabs 158 and
160 prevent the entire rack assembly from sliding out of the oven
when the user pulls on rack 132 to slide it out of cavity 116.
However, by lifting up on the entire rack assembly 132 using e.g.,
handle 146 and loops 148, 150, the user can raise any particular
rack assembly 132 out of a pair of frames 120 and remove the same
from oven cavity 116 as desired.
[0033] FIG. 7 is an end view of one corner of rack assembly 128
positioned on frame 120, as would be observed from the rear of
cavity 116 along one of the walls 118 forming oven chamber 116.
FIG. 8 is a side view of another corner of rack assembly 128 as
positioned on frame 120. As shown, outer bracket 140 (and 142) rest
on the horizontal supports 122 provided by frames 120 that are
mounted on opposing walls 118.
[0034] When a user withdraws a rack 132 from cavity 116, a moment
is created that will attempt to lift the rear portion of rack
assembly 128 as shown in FIGS. 7 and 8 in an upward direction U.
This moment will be increased by the weight of a food item and/or
cooking utensil placed on rack 132. Also, the amount by which rack
132 is extended from cavity 116 will also increase this moment.
[0035] Accordingly, each vertical support 124 is provided with a
stop 162 that extends over the rear portions of outer bracket 140
and outer bracket 142 on each side of rack assembly 128. For the
exemplary embodiment, stops 162 are project outwardly form an
opposing side wall, into oven cavity 116, and are orthogonal to
horizontal supports 122. By way of example, stop 162 can be a metal
sheet or other element that is welded to vertical support 124. Stop
162 operates to prevent the movement of rack assembly 128 along
upward direction U when rack 132 is extended from the oven cavity
116. At the same time, stop 162 does not prevent a user from
removing rack assembly 128 from oven 100 by sliding assembly 128
along horizontal supports 122 and out from under stop 162. As will
be understood by one of skill in the art using the teachings
disclosed herein, a variety of other configurations shapes may be
used for stops 162 as well.
[0036] For the top-most rack assembly 128 in oven 100, a stop 175
is located on each opposing side wall 118 as shown in FIGS. 2 and
9. Stop 175 extends over the rear portion of each of the slide
assemblies associated with the top-most rack assembly 128. Other
configurations can be used to provide stop 175 as well. For
example, frame 120 can also be equipped to provide a stop for the
top-most rack assembly 128.
[0037] This written description uses examples to disclose the
invention, including the best mode, and also to enable any person
skilled in the art to practice the invention, including making and
using any devices or systems and performing any incorporated
methods. The patentable scope of the invention is defined by the
claims, and may include other examples that occur to those skilled
in the art. Such other examples are intended to be within the scope
of the claims if they include structural elements that do not
differ from the literal language of the claims, or if they include
equivalent structural elements with insubstantial differences from
the literal languages of the claims.
