Oven muffle having rack-support embossments at a lower position and associated structural features

An oven muffle, comprising:

• a cavity wrapper including a rear wall and opposing side walls;
• and
• a bottom cap including a bottom wall and a peripheral skirt extending away from the bottom wall, wherein the cavity wrapper and the bottom cap at least partially define a cooking chamber having a front opening,
• wherein when viewed in cross-section a lateral portion or segment of the peripheral skirt has first and second curved sections and a linear section disposed vertically between the first and second curved sections,
• the bottom cap comprising a lower rack-support embossment stamped at least partially in said lateral portion or segment of the peripheral skirt at least partially overlapping said linear section when viewed in cross-section.

A cooking appliance, comprising:

• an outer cabinet;
• a muffle disposed within the outer cabinet, the muffle comprising a cavity wrapper disposed between and connected to each of a bottom cap and a top cap, wherein the top cap, the bottom cap, and the cavity wrapper collectively define a cooking chamber having a front opening, and wherein the top cap includes a top wall, the bottom cap includes a bottom wall, and the cavity wrapper includes a pair of opposing side walls and a rear wall,
• a door movably coupled to the outer cabinet to selectively close the front opening of the cooking chamber;
• and
• a heating element disposed within the cooking chamber,
• the bottom cap having a pair of opposing lateral skirt portions or segments extending away from respective opposing lateral ends of the bottom wall, each said skirt portion or segment extending towards a respective one of the opposing side walls of the cavity wrapper and joined thereto via a weld seam,
• each of the opposing lateral skirt portions or segments having, when viewed in cross-section, first and second curved sections and a linear section disposed between the first and second curved sections,
• each of the opposing lateral skirt portions or segments having a lower rack-support embossment formed integral therewith at a location vertically beneath the weld seam, and
• each of the lower rack-support embossments having at least two embossed features extending into a volume of the cooking chamber, wherein each of the at least two embossed features has a respective contour that is or converges to tangent to the linear section of the respective lateral skirt portion or segment.
