Description

Technical Field

[0001] This invention relates to pizza ovens, and more particularly to an oven equipped with a surface cooling system. Background Technology

[0002] Existing pizza ovens, designed for rapid baking, typically have high core temperatures, reaching 370 degrees Celsius. This results in a high surface temperature on the outer shell, posing a risk of burns to consumers. Traditional heat dissipation structures cannot evenly distribute heat within the upper shell, leading to some areas cooling significantly while others remain hot. Therefore, to address these issues, a structure is needed to improve heat dissipation on the upper surface of the outer shell. Furthermore, the design must address the uneven heat dissipation problem, achieving both improved cooling efficiency and uniform heat distribution.

[0003] Therefore, existing pizza ovens need further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide an oven with a surface cooling system that can both improve heat dissipation and ensure uniform heat dissipation.
