The presentlnventlon pertains to stoves, ranges andthe like, and more particularly toan improved construction of the oven thereof.

It'is an object of the tide an air vent arrangement for an oven chamher whereby cooking vapors of relatively high temperature are vented into a second compart-- to he slowly dissipated to the atmosphere L various openings of the compartment which ere not sealed in air tight relation.

it is another object of the present invention. to l "e a vent arrangement for an oven chamber is simple in construction, economical of mature and highly efiioient in use. i

Walls which are space-cl from hesitation materiel it therehetween.

mp-srtment ferthe interposition present invention to pro ioh are sliolably mounted at to the rear side of The sides, top and bottom walls of the liner '44 extend forwardly through an opening in the front wall of the range and is marginally flanged, as at 49, to overlie the edge of the front an access opening to the chamber 45.

The opening 50 is closed by a. suitalgle door 52 comprising :in outer pan 54 and an inner pan 56 held in spaced apart relation with heat insulation material 51 therebetween. The door is hingedly mounted to the cabinet at so as to Swing downwardly into a horizontal plane. The hinges are of the concealed type and co nprise an axially movable hinge pin 60 slidably mounted in a U-shaped member 8! whioh'ls secured to the outer pan 56 to lie between the outer end inner pan of the door. The pin 60 extends through an opening in the side wall of the outer pan to he journalecl in a, lug member 62 which is secured to a. supporting plate member 64. The mete member so is secured by weld or the like the front wall 32, with the lug member projecting outwardly through an openillg in the front well the door between the side walls of the inner end outer pan. The side wall (it? of the inner pen is bent to extend a spatial distance from the side well oi the outer nan to permit the reception therehetween of the lug 55 the edge of member. The hinge pin to is held journeied in the hag memher by spring (5'5, one enci of which is tensioneci against a lee of the member Ell and the other end messes against 9, when M fixed upon the pie, fisn erzn amxeci to door 52' projects thr ugh opening in iront wall of the oshinet into the eompartment 38., A spring H is provided enei (not shown) is secured to well of the eehinet 2t.

The hlnging of the oer 52 is so arranged that the top is swung past the vertical center of the hinge pin so that the ten of the elem rests against the edge of the ciooz 'opening an sealing relationship therewith to prevent en trance of air therethrongh into the oven ehamheii The bottom portion of the door is spaced; from panel forming its Iowergcorners' for inning the door to olosed peesit/ion, one end efiixed to an ereuete arm- "FQQanol its opposite to plate member Gt ere the opening to provide a restricted 'prior to circulation in chamber 45 adapted for heating the circulating air therein. A second heating element 82 is secured adjacent to the top wall of the oven chamber adapted to serve in pre-heating the chamber, and for broiling. A baiiie member 94 is supportingly secured to and over the heating element 90 adapted to direct the circulation of air over the heating element 90. The baflle member 84 and heating element 80 are arranged relative to the opening 15 so cold air over the heating element to be heated the oven chamber. An outlet vent is provided for venting vapor from the oven chamber comprising a tubular member 96 extending from the oven chamber into compartment 38 forming a communicating passageway 91 therebetween. I

By the present arrangement cold air is drawn into the oven chamber through the restricted passage 15, directed by the baille member towards and heated by the heating element 90 prior to its circulation in the oven chamber. Cooking vapors and steam arising from the use or baking operation in the oven chamber is vented through the passageway 91 directly into the compartment 35 where it is cooled and difiusedto the atmosphere. Atmospherical air circulates ireely through the compartment as no seal is provided by the drawers around the drawer openings, or the surface units, and an opening Hill is provided in the rear wall of the cabinet. It will be noted that the vent is positioned to discharge the stream of vapors from the oven chamber adjacent to the rear portion of the compartment 3.. As the temperature of the discharging vapors is relatively high it is highly desirable to so locate as to direct the entering tioning the vent the discharge the vent outlet that the user does not come into bodily contact with the discharge and by so posiis readily diflused in the compartment with little likelihood that the user will come accidentally near the outlet to sufier physical burns or scalds from the discharge during the use or operation of the oven.

By venting into an adjacent compartment there is permitted a short direct passage which allows an unimpeded flow therethrough and eliminates the need of precooling the vapors in the passageway as would be necessary where it is directly discharged externally oi the cabinet so as to prevent burning or scalding the user working about the range.

While I have shown and described the preferred forms of my invention, I do not wish to limit myself to the precise details as shown but wish to avail myself of such variations and much flcations as may come within the scope of the appended claim.

I claim:

Range apparatus comprising an outer casing. an inner casing forming a chamber and being arranged so that it is in spaced apart relation to the outer casing, heat insulation between said casings, said inner casing forming an access opening to said chamber, a door for closing said opening and having a portion set away at the lower part thereof from the lower part of said opening to form a restricted air inlet passage to said chamber, a heating element in said chamber extending from adjacent said restricted opening to the rear of said chamber, abaflle over said heating element for directing the flow of incoming air over said heating element. and venting means in the upper rear portion of said inner casing above said baiile for venting said air into the interior of said outer casing.
