Air-tight removable divider and thermal break

A divider assembly for dividing an enclosed cooking cavity of an oven into two cooking subcavities, the oven including a first side wall and a second side wall within the enclosed cooking cavity, the first and second side walls including respective first and second divider rail embosses extending horizontally, the divider assembly comprising:

• a panel having a top surface, a bottom surface, and first and second side edges, the first side edge comprising a first recess and the second side edge comprising a second recess;
• a first movable closure positioned within the first recess;
• a first plurality of springs positioned within the first recess for biasing the first movable closure out from the first recess while allowing the first movable closure to slide inward inside the first recess;
• a second movable closure positioned within the second recess;
• and
• a second plurality of springs positioned within the second recess for biasing the second movable closure out from the second recess while allowing the second movable closure to slide inward inside the second recess,
• wherein the first and second movable closures are configured to extend into the respective first and second divider rail embosses so as to lock the divider assembly in place while increasing an airtightness and reducing heat migration.

A method of dividing an enclosed cooking cavity of an oven into a first cooking subcavity and a second cooking subcavity, where the oven includes first and second side walls each having a respective first and second divider rail emboss extending horizontally, the method comprises:

• providing a divider assembly within the enclosed cooking cavity so as to divide the enclosed cavity into the first cooking subcavity and the second cooking subcavity, wherein the divider assembly comprises:
• a panel having a top surface, a bottom surface, and first and second side edges, the first side edge comprising a first recess and the second side edge comprising a second recess;
• a first movable closure positioned within the first recess;
• a first plurality of springs positioned within the first recess for biasing the first movable closure out from the first recess while allowing the first movable closure to slide inward inside the first recess;
• a second movable closure positioned within the second recess;
• and
• a second plurality of springs positioned within the second recess for biasing the second movable closure out from the second recess while allowing the second movable closure to slide inward inside the second recess,
• wherein the first and second movable closures are configured to extend into the respective first and second divider rail embosses so as to lock the divider assembly in place while increasing an airtightness and reducing heat migration.
