Description

Technical Field

[0001] This utility model relates to the field of pizza oven technology, and in particular to a multifunctional dual-heat-source pizza oven. Background Technology

[0002] A pizza oven is a cooking device specifically designed for baking pizzas. Its core function is to quickly achieve a crispy crust, melted cheese, and fully cooked ingredients by precisely controlling temperature and heat distribution. Unlike traditional ovens, pizza ovens can typically reach the required high temperature in a very short time, locking in moisture through short-duration baking while creating the crust's characteristic caramelized spots and fluffy texture. Its heat source design simulates the combination of radiant and convective heat from a traditional brick kiln, ensuring even heat penetration to the crust and top. Commercial pizza ovens can handle large volumes of orders continuously, maintaining consistent production; home models balance compactness with professional-grade baking results. Some high-end models also support humidity control to prevent the crust from drying out. Whether it's the Maillard reaction of Italian thin-crust pizza or the soft inner crust of American thick-crust pizza, the pizza oven achieves optimal taste through targeted heat distribution, making it a core piece of equipment for pizzerias and baking enthusiasts.

[0003] Existing pizza ovens have several shortcomings. First, they can only use a single heat source and cannot select different heat sources according to needs. Second, they only have a single combustion hole on the bottom side of the pizza baking chamber, which results in an unsatisfactory baking effect. Third, they lack a rotating mechanism in the pizza baking chamber, which cannot rotate the pizza and results in poor baking uniformity.

[0004] In view of this, the inventors hope to optimize and improve the existing pizza oven. Summary of the Invention

[0005] The purpose of this invention is to overcome at least one of the problems existing in the conventional technology and to provide a multifunctional dual-heat-source pizza oven.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A multi-functional dual-heat-source pizza oven includes an inner cover, an outer cover, a combustion hood, and a smoke exhaust hood. The outer cover is provided on the outside of the inner cover, the combustion hood is connected to the bottom side of the outer cover, and the smoke exhaust hood is connected to the top side of the outer cover. The combustion hood has a wood combustion chamber with an opening at the front end, and a primary combustion flame hole is provided on the partition between the combustion hood and the outer cover; The inner cover has a pizza baking chamber with an opening at the front end, and the upper arched wall of the pizza baking chamber has two rows of secondary combustion flame holes symmetrically opened. An annular heating zone is formed between the inner and outer covers. The bottom of the annular heating zone is connected to the wood combustion chamber through a primary combustion flame hole. The lower top of the annular heating zone is connected to the pizza baking chamber through a secondary combustion flame hole. The upper top of the annular heating zone is connected to the inner cavity of the exhaust hood.

[0007] Furthermore, in the aforementioned multifunctional dual-heat-source pizza oven, the combustion hood is provided with several sets of air inlets symmetrically on both sides of the wood combustion chamber.

[0008] Furthermore, in the aforementioned multi-functional dual-heat-source pizza oven, a support frame is installed at the bottom of the combustion hood.

[0009] Furthermore, in the aforementioned multifunctional dual-heat-source pizza oven, a gas burner head is installed on the baffle plate at the bottom of the annular heating zone, located around the primary combustion flame hole.

[0010] Furthermore, in the aforementioned multifunctional dual-heat-source pizza oven, the back panel of the inner cover is directly or indirectly fixedly connected to the back panel of the outer cover.

[0011] Furthermore, in the aforementioned multifunctional dual-heat-source pizza oven, the spacing between the two rows of secondary combustion flame holes is greater than the inner cavity width of the exhaust hood.

[0012] Furthermore, in the aforementioned multi-functional dual-heat-source pizza oven, a rotary mechanism capable of rotating the pizza is installed on the lower side wall of the pizza baking chamber.

[0013] Furthermore, in the aforementioned multifunctional dual-heat-source pizza oven, the rotary mechanism includes an annular seat, a turntable, a driven gear ring, a rotary drive motor, and a drive gear. The turntable is movably supported inside the annular seat, and the turntable has several hollow holes inside. The driven gear ring located inside the annular seat is located at the outer edge of the turntable. The rotary drive motor is fixed on the upper side of the annular seat and distributed near the inner end of the pizza baking chamber. The output end of the rotary drive motor is equipped with a drive gear that extends into the annular seat, and the drive gear meshes with the driven gear ring.

[0014] Furthermore, in the aforementioned multi-functional dual-heat-source pizza oven, the annular base and turntable are made of stainless steel.

[0015] Furthermore, in the aforementioned multifunctional dual-heat-source pizza oven, the rotary drive motor is an adjustable-speed, high-temperature resistant motor.

[0016] The beneficial effects of this utility model are: 1. It adopts a two-stage combustion system to improve efficiency. The first stage of heating stores heat and stabilizes the temperature, while the second stage of heating enhances the caramelization of the pizza surface and shortens the baking time. It has a high fuel utilization rate. The second stage of combustion allows the wood to fully decompose, reducing smoke and dust generation and achieving energy saving. The volatile substances of fruit wood permeate the pizza through the second stage of combustion, giving it a unique smoky flavor. The arched top double-row flame hole design simulates the radiation + convection combination of traditional brick kilns to avoid local overheating.

[0017] 2. A gas burner head is installed on the partition at the bottom of the annular heating zone, with the gas pipeline passing through the back panel of the outer cover and the gas supply controlled independently. This method allows for free switching or combination of dual heat sources. When using the wood mode, the two-stage heating process is retained; when using the gas mode, wood combustion is turned off, and the gas flame directly enters the annular heating zone; if necessary, the dual sources can be superimposed to achieve rapid heating.

[0018] 3. The lower side wall of the pizza baking chamber is equipped with a rotary mechanism that can drive the pizza to rotate. After the motor is started, the gear set drives the turntable to rotate at a constant speed, so that the pizza rotates during baking; the perforated holes allow the bottom heat to directly contact the bottom of the pizza, avoiding heat blockage; the motor is a high-temperature resistant and adjustable type, which can adapt to the speed requirements of different sized pizzas.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
