Description

Technical Field

[0001] This utility model relates to the technical field of oven and microwave oven combination appliances, specifically an oven and microwave oven combination appliance for making roujiamo (Chinese hamburger). Background Technology

[0002] Currently available heating equipment for roujiamo (Chinese hamburger) generally suffers from uneven heating. Traditional ovens tend to result in a hardened outer crust while the filling remains cold, while microwave ovens, when used alone, exhibit localized overheating or underheating due to the standing wave effect. This is particularly problematic for multi-layered, complex foods like roujiamo (bread + meat filling + fat), where current technology struggles to simultaneously achieve a crispy outer crust and evenly heated filling. Commercial equipment often employs staged heating methods, which are not only time-consuming and energy-intensive but also complex to operate. Furthermore, the fixed waveguide design of ordinary microwave ovens causes significant differences in microwave energy absorption across different parts of the roujiamo, frequently resulting in uneven heating—overheating at the edges and a cold center. These issues severely impact the reheating quality and taste of roujiamo. Therefore, this application proposes an integrated oven and microwave oven for roujiamo to address these problems.
