OVEN VENT FOR SMOOTH TOP RANGE
Abstract
A smooth top range having a vent for venting hot oven gases
through the continuous panel cooktop portion. The vent is arranged
to direct the gases away from manually operable control elements
disposed on the cooktop so as to avoid high temperature conditions
thereof and to avoid directing of the hot gases against a user
thereof.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to cooking ranges, and in particular to
means for venting such ranges.
2. Description of the Prior Art
In the conventional cooking range having an oven portion and a
cooktop portion, means may be provided for venting the oven through
the cooktop portion. Thus, as shown in United States Letters Patent
No. 2,384,262 of Earl F. Rutan, the oven may be vented through the
center of the cooktop heating elements.
In United States Letters Patent No. 2,375,047 of Ernest E.
Sutherland, a vent is provided for venting the oven through the top
wall of the range overlying the oven. In United States Letters
Patent No. 2,387,734, of Alfons Barnsteiner, a vent is provided
adjacent the surface units of the cooktop adjacent the portion of
the top surface of the range overlying the oven. In the Barnsteiner
heating apparatus, the outlet from the vent directs the air over
the entire cooktop surface.
In an improved form of range presently commercially available, the
cooktop of the range comprises a continuous panel of a
glass-ceramic material effectively defining a smooth top. The
cooktop includes a cooking surface portion, and a control portion
conventionally at one side of the cooking surface portion on which
are provided suitably manually operable control knobs for
selectively controlling the operation of the individual cooktop
heating elements. As such cooktops are effectively sealed across
the top of the range and have no openings therethrough for passing
the hot gases from the oven, a problem has arisen in the venting of
hot oven gases in a manner to prevent harmful heating of the range
controls while effectively venting the oven.
SUMMARY OF THE INVENTION
The present invention comprehends the provision, in a range having
a continuous panel cooktop, of improved means for venting the oven
portion thereof. More specifically, the invention comprehends
providing, in such a range construction, a vent extending from the
oven to adjacent the control portion of the cooktop, and means for
directing the hot vented gases away from the manually operable
control elements of the control portion.
In the illustrated embodiment, the vent passage is defined by a
duct extending from the oven through a rear portion of the control
portion of the cooktop. An outlet grill is provided for directing
the vented gases rearwardly and laterally of the rear control
portion and effectively preventing discharge of the gases forwardly
to the manually operable control elements. Thus, the control
elements are prevented from becoming excessively heated by the
vented gases and the gases are prevented from acting directly on
the user's hands in the operation of the control elements in the
normal use of the range.
The range oven venting means of the present invention is extremely
simple and economical of construction while yet providing the
highly desirable features discussed above.
BRIEF DESCRIPTION OF THE DRAWING
Other features and advantages of the invention will be apparent
from the following description taken in connection with the
accompanying drawing wherein:
FIG. 1 is a fragmentary perspective view of a range having an oven
venting means embodying the invention;
FIG. 2 is a fragmentary plan view thereof;
FIG. 3 is a fragmentary enlarged vertical section taken
substantially along the line 3--3 of FIG. 2; and
FIG. 4 is a fragmentary broken vertical section taken substantially
along the line 4--4 of FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In the exemplary embodiment of the invention as disclosed in the
drawing, a range generally designated 10 is shown to include an
oven portion 11 and a cooktop portion 12. Oven portion 11 may
include a conventional front door 13 and suitable manually operable
controls 14. In the illustrated embodiment, range 10 comprises a
set-in range which may be set into a suitable kitchen base cabinet
15, it being understood that the invention is applicable equally to
both set-in and freestanding ranges.
Cooktop 12 comprises a continuous panel cooktop such as
conventionally referred to as a glass-ceramic smooth cooktop. The
cooktop includes a cooking surface portion 16 and a control portion
17 with an overlying frame 18 conventionally formed of stainless
steel and including a divider strip portion 19 conventionally
dividing the cooking surface portion from the control portion. Such
smooth cooktop constructions effectively define a continuous panel
top of the range in that there are no open portions normally
capable of providing venting of the subjacent oven 11 as are
available in conventional ranges utilizing heating elements which
define portions opening to the subjacent interior space of the
range. Thus, it is desirable to provide some auxiliary means for
venting the hot gases from the oven during the operation of the
oven and the present invention is directed to the concept of
venting such gases to a rear portion of the cooktop.
More specifically, as seen in FIG. 1, the invention comprehends
providing a duct 20 having an inlet 21 overlying the oven 11 and an
outlet 22 extending through the control panel portion 17 rearwardly
of knobs 23 of controls 14. A grilled deflector 24 is mounted on
the control panel 17 to direct the hot gases from outlet 22
rearwardly and laterally away from the control knobs 23 as
illustrated in FIGS. 1 and 2. As shown, the hot gases directed to
the left by grilled deflector 24 flow along the rear of cooktop
portion 16 and the hot gases which are directed to the right from
grilled deflector 24 are directed laterally away from the range.
The gases directed rearwardly may flow upwardly along the rear wall
surface 25 behind the range.
Control panel 17 is provided with a suitable opening 26 through
which outlet 22 extends, as shown in FIG. 3. Outlet 22 may comprise
a flanged sleeve receiving the upper end 27 of the vent duct 20
with the outturned flange portion 28 of outlet 22 resting on the
panel about opening 26.
Grilled deflector 24 may be provided with a pair of suitable
depending connecting posts 29 extending downwardly through suitable
openings in panel 17 and subjacent control switch support 30.
The deflector includes an imperforate front wall 31 and an
imperforate top wall 32. The side walls are provided with suitable
openings 33 and the rear wall is provided with a suitable opening
34 for conducting the hot oven gases laterally and rearwardly from
the deflector as discussed above.
As shown in FIGS. 1 and 2, the grilled deflector may extend
substantially fully across the width of the control panel portion
17.
In the illustrated embodiment, grilled deflector 24 comprises a
cast element formed of a suitable metal, such as zinc, which may
have a decorative finish by suitably selectively providing
satin-brushed and bright polished areas. The control knobs 23 may
be formed of a suitable temperature-resistant synthetic resin, such
as Marbon-Cycoloy KHP, manufactured by Borg-Warner Corporation,
comprising an alloy of synthetic polymers with ABS resins.
The use of grilled deflector 24 effectively prevents injury to the
user of the range by avoiding contact of the hot vented gases from
the oven with either the control knobs 23 or with the user's hands
when the user is manipulating the control knobs 23 in controlling
operation of cooktop 12, while yet the hot gases may be vented
closely adjacent the control knobs effectively minimizing space
requirements in the range. Thus, the invention comprehends
providing such an improved range construction which may be arranged
in a conventional manner as regards the layout of the cooktop,
controls and relationship of the oven to the cooktop.
The foregoing disclosure of specific embodiments is illustrative of
the broad inventive concepts comprehended by the invention.
