Jan. 29, 1957 G. w. KAMlN RANGE FLUE STRUCTURE Filed May 4. 1954 INVENTOR. Geog? WZKQWWN ATTORNEYS United States PatntO RANGE FLUE STRUCTURE George W. Kamin, Lombard, Ill., assignor to Cribben Sexton Company, Chicago, 111., a corporation of mors Application May 4, 1954, Serial No. 427,500

Claims. (Cl. 126-21) mined that the vents or oven lines should be located so that they are not obstructed and will not be restricted by accumulation of dust and dirt, etc, adjacent or within the flue. These factors have brought about designs in which "the flue outlet is in the front of the stove and along the face of the back splasher thereof.

The result of such developments has been generally a marring of the appearance of the range with the unsightly flue outlets. Further, the hot flue gases discharging from the flue in the area of the back splasher has caused the back splasher to heat up excessively and moreover the flow of the hot gases if restricted at all brings about an additional build-up of the back splasher temperature. The flue outlets and back splasher adjacent these outlets have been difficult to clean and the accumulation of stain,

etc, further contributes to the general unsightliness of the ranges.

It is accordingly an object of this invention to provide flue or vent structures particularly suited for use in kitchen ranges that will overcome the disadvantages present in prior art structures. a concealed oven flue in the face of a range back splasher whereby the appearance of the range is not blemished by an unsightly flue, yet to arrange the flue so that the flow of hot gases therethrough is unrestricted and, moreover, so that the hot gases are directed outwardly and away from the back splasher. Still another object is in the pro vision of an oven flue that has an outlet in the face of the back splasher which isnormally concealed by a light panel, the panel being removable whereby the flue and I back splasher can be quickly, easily and thoroughly cleaned.

A further object is in providing anoven-flue structure extending through the back splasher of the range but 1n spaced relation therewith so that there is substantially no metal-'to-metal contact between the two and direct conduction of heat is thereby minimized. Yet a further object is to provide structure as described in which an opening of substantial size is provided about the flue so that cool air may circulate freely thereabout and, further, wherein the flow of cool air about the flue is induced by the discharge of the hot gases therefrom. Additional objects and advantages will appear as the specification proce'eds.

An embodiment ot the invention is illustrated in the accompanying drawing, in which- Figure l is a broken perspective view showing a coo;-

ing range embodying the invention; and Fig. 2 is a ver tieal sectional view taken through substantially the center of the flue shown at the left in Fig. l and looking toward .thej sh a 9 thefangeq H '1 Shown in the figures of the drawing'is a cooking stove Another object is to provide or range that is designated generally with the letter A. The range A may be substantially conventional insofar as the majority of the functional parts thereof is concerned and the range A is provided with a closed cooking compartment 10 that may be an oven or broiler compartment, etc. The compartment 10 is partially defined by an upper wall 11 that is covered with an insulation 12 to minimize the loss of heat from the compartment 10. A. division panel 13 is mounted above the wall 11 in spaced relation therewith and the insulation 12 is confined between the two walls or panels 11 and 13.

The range A is also provided with the usual top wall 14 which will be provided with a plurality of burners, etc, which are not shown. The top is spaced above the division panel 13 and a compartment 15 is provided therebetween that will accept the necessary burners, conduits and support structures therefor, none of which are shown. Extending upwardly from the top wall 14 and at a slight inclination is a back splasher 16. If desired, the top wall 14 may have an upwardly-turned corner portion 17 equipped with a flange 18 and the flange 18 may be welded or otherwise rigidly secured to a rearwardlyturned flange 19 provided along the lower longitudinal edge of the back splasher 16.

The back splasher 16 inclines upwardly and rearwardly and along the upper edge thereof it is equipped with a rearwardly-turned top wall 20 that has formed integrally therewith a downwardly-turned flange 21 which is spaced from and rearwardly of the face or front of the back splasher 16. The back splasher is also provided with side walls 22 which merge with the side Walls 23 provided by the stove or range A.

' The oven space or compartment 10 is equipped with a rear wall 24 that is provided with an enlarged vent opening. or discharge port 25 therethrough adjacent the wall member 11 defining the upper limits of the compartment 10. A vent or flue structure 26 provided by an openended conduit 27..communicate-s at the lower end thereof through the port or opening 25 with the interior of the oven compartment 10. Preferably the flue 26 is rigidly secured about the Opening 25 so that all of the exhaust gases escaping from the compartment enter the flue 26 and are carried upwardly therethrough. This rigid sealing mounting about the opening 25 may be accomplished by equipping the conduit 27 with a downwardly-turned flange 28 that is welded or otherwise rigidly secured to the back wall 24 of the oven compartment. it will be appreciated that the conduit 27 will also be equipped with outwardly-turned flanges along the sides thereof which will be similarly secured to the back wall 24 of the oven compartment. in further providing a rigid structureit is seen that the divider panel 13 may haveformed in tegrallytherewith an upwardly-turned ledge or flange 29 that is in abutting relation with the wall portion 30 of the conduit 27 and the members 29 and 30 are rigidly united in any suitable manner.

By referring to Fig. 1 in particular it can be seen that the flue 26 can be considered as having an enlarged and substantially closed bottom end portion that is provided along the forward wall thereof with an opening 31 that is in register with the opening 25 provided in the rear wall of the oven compartment. From this enlarged end portion at the bottom of the flue 26 the side walls 32 and '33 thereof taper inwardly and upwardly and are of substantially an inverted V-shape. The upper end portion of splasher 1d the back splasher is pressed inwardly along the face thereof to provide the elongated recess or chanincl 36,. channel 5.6 is provided with an arcuate rear wall at that curves inwardly and downwardly and mer es at its lower end with the outwardly and downwardly inclined bottom wall 38. The ends of the channel or depr ssed porti n 36 are defined y the w lls 3*? e s best in Pia The bott m Wall 3 of th channel or ecess 36 i p ovided with an n arg d pen n 40 herethrc gh tha readily accepts the upper end portion of the flue 26. Preferably the opening 40 considerably larger than the flue 26 at the area thereof that passes through the bottom .wall 38 of the channel. It will also be noted that the rear wall of the flue is generally arcuate and is substantially parallel with the arcuate rear wall 37 of the channel 3d. The flue and the wall 37 are spaced apart to provide an open flow channel 41 therebetwecn as seen in Fig. The rear wall of the hue 26 terminates slightly below and in, wardly from the face of the back splasher l6 and the arcuate wall 37 then provides in efiect a continuation of the rear wall of the flue. On the other hand, the forward wall of the flue 26 extends upwardly and outwardly beyond the edge of the rear wall of the flue and as a result the flue opening 35 is inclined upwardly and forwardly.

The upper end portion of the line 26 is substantially concealed by the elongated, arcuate panel 42 which extends from one end to the other of the back splasher 16 and substantially encloses or conceals the entire channel or recess 36. The panel 42 is provided with an upper longitudinal edge 43 which is spaced forwardly from the face of the back splasher 16 and thereby provides an elongated slot or opening 44 through which hot gases dis charging from the flue'outlet 35 may escape. The panel 42 is held in position enclosing the recess 36 and substantially concealing the upper end of the flue 26 by means of the holders or sockets 45 which are provided adj cent each end of the back. splasher 16' and which are rigidly secured thereto. The panel 42 is releasably carried by the members 45 and for this purpose the members 45 are equipped with slots or recesses into which the end portions' of the panel 42 may be inserted or removed therefrom. Mounting members of this character are well known in the art and for this reason a more elaborate description and illustration thereof is believed unnecessary.

It will be noted in Fig. 1 that only one of the members 25 i ranges are now provided is mounted behind this panel.

Such a light source will preferably be mounted intermediate the ends of the back splasher lfibut since such light sources may be wholly conventional and are well known in the, art a SllQwing and description thereof is not presented. The lower longitudinal edge portion 36 of the light. Pan l. 4.2 is, spaced fro t e k sp she 16 as She he draw ng s that lig pro ide y h l gh ,c will. b direct d downwardl and u wa dly al n the face of the back splasher If desired, the light panel 42 may be equipped centrally with a name plate s p/that the trade name or inanufacturers name may be presented at a convenient location on the range.

It will be noted in Fig. 1 that a pair of line structures are pro ideduch an ar ang nt is pr fi r b e wh r the ran e A s cent ha with a pa r o epar e co kin enc osures. r corn. rtment n such e en it ill b nec ssa y to separately vent each o th enclosed cock n compartments. The flue structure appearing at the right of Fig 1 is designated with the numeral 43 and since its mounting, function, etc, are identical with the flue 26 which has been described in detail a detailed description of the flue member 48 will notbe set. out.

open ng 31 in he forwar w l these? h lis ease rise within the flue and eventually are discharged out wardly through the open upper end 35 thereof. In the event that a pair of cooking compartments are provided and a pair of lines, the same conditions take place within the flue structure 48,

The outlet 35 of the flue is oriented so that the hot gases escaping therefrom are directed forwardly and upwardly and away from the face of the back splasher 16. The 26 is spaced from the back splasher 16 and there is substantially no heating up of the back splasher through direct conduction of heat from the flue and to the back splasher. The rear wall 34 of the flue is spaced from the rear wall 37 of the recess or depressed channel portion 36. Thus there is suflicient clearance for the free circulation of air about the flue and such circulation of air will maintain the back splasher 16 in a relatively cool condition even through the flue structure 26 heats up considerably.

it will be noted that between the flue wall 34 and channel wall 37 a flow passage 41 is provided. When the hot gases discharge through the outlet 37 of the fine a nozzle effect is established and the flow of relatively cool air upwardly through the passage 43. is thereby induced. Thus while the oven or cooking compartment 19 is in use the hot gases flowing through the flue 26 and outwardly therefrom actually cause a flow of cool air upwardly and about the back splasher and upper end of the flue and these cool gases are effective to maintain the back splasher in a relatively cool condition.

The range provided is very attractive, for the unsightly flue and the outlet opening thereof is concealed by the elongated light panel 42 which extends substantially from one end to the other of the back splasher. Yet the panel 42 is relcasably carried by the mounting members 45 and the back splasher, particularly in the areas. of the fines, can be cleaned readily by simply removing the light panel 42 which provides access to the channel 36 throughout its entire length and also to the lines 26 and 48 which extend upwardly and through the back splasher.

While in the foregoing specification an embodiment of the invention has been set out in considerable detail for purposes of illustration, it will be apparent to those skilled in the art that numerous changes may be made in these details without departing from the spirit and principles of the invention.
