Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pizza ovens, and particularly relates to a pizza oven. Background Art
[0002] In the prior art, as an important device for quickly cooking pizza, the structural design and working principle of a pizza oven are directly related to the baking efficiency and quality of pizza. Taking the pizza machine disclosed in the technical solution with the publication number CN211093506U as an example, the device mainly consists of a housing (including an upper cover and a lower cover) and an electric heating mechanism (including an upper electric heating component and a lower electric heating component). This design allows the pizza to receive heat from both above and below during the baking process, thereby achieving double-sided heating and greatly improving the baking efficiency.
[0003] However, in the actual application process, such pizza ovens face a significant heat dissipation problem. Since both the upper cover and the lower cover are heated during the baking process, and the lower cover has a higher temperature because it directly bears the baking tray, the traditional heat dissipation method mainly relies on the pores on the upper cover and the lower cover for natural heat dissipation. Although this method can meet the heat dissipation requirements of the upper cover to a certain extent and ensure that the temperature of the upper cover drops within the safety standard, for the lower cover, its heat dissipation effect is often unsatisfactory.
[0004] For example, the upper and lower ends of the baking tray are heated by the upper electric heating component and the lower electric heating component respectively, and the overall temperature of the baking tray is relatively high. Since the baking tray is placed on the lower cover, when the lower cover is heated by the lower electric heating component, the heat of the baking tray is also transferred to the lower cover, resulting in the surface temperature of the lower cover often being much higher than that of the upper cover. Even if the upper cover reaches the safety standard through pore heat dissipation, the surface temperature of the lower cover may still remain at a relatively high level. This not only increases the risk of scalding for users during the use process but also may have an adverse impact on the stability and lifespan of the device. Content of the Utility Model

In this embodiment, by providing the first heat insulation cavity 14 and the second heat insulation cavity 15, the efficiency of heat transfer is reduced, the temperature of the outer surface of the lower plate assembly 1 is effectively reduced, thereby reducing the risk of the user being scalded. Moreover, through the design of the first heat insulation cavity 14 and the second heat insulation cavity 15, more heat is retained in the pizza oven, improving the baking speed and quality of the pizza.
[0028] As a preferred embodiment, a cooling fan 3 for extracting the heat in the first heat insulation cavity 14 and discharging it to the outside of the pizza oven is provided on the lower plate housing 11.
