Abstract: A heat spreading/temperature uniformity device for a bake oven is disclosed. The heat spreading/temperature uniformity device is applicable to the bake oven, including at least one rack body movably disposed in a receiving space defined by the bake oven, and multiple heat spreading members distributed over and arranged on the rack body and integrally connected therewith. Each heat spreading member and the rack body contain a first angle and a second angle. The heat spreading/temperature uniformity device is up and down adjustably disposed in the bake oven for transferring heat to the relatively low heating intensity areas of the receiving space in the form of heat radiation. Accordingly, the food placed in the bake oven can be uniformly heated at a uniform heating intensity and a uniform temperature.
