Description

Technical Field

[0001] The present invention relates to the technical field of pizza ovens, in particular to a pizza oven for outdoor use. Background Art

[0002] As pizza is introduced into China, it is now loved by more and more people. The pizza making technology is becoming more and more mature. Homemade pizza has become a pleasure. More and more people make pizza at home or when camping outdoors. However, the existing outdoor pizza ovens emphasize portability and have a relatively simple structure. There are problems such as slow heating and uneven heat conduction in the oven, which makes outdoor pizza baking inefficient and affects people's camping experience. Summary of the Invention

[0003] The purpose of the present invention is to provide a pizza oven for outdoor use, which improves the technical problem of low efficiency in making pizza caused by slow temperature rise in the existing outdoor pizza oven.

[0004] To achieve the above-mentioned objectives, the present invention provides a pizza oven for outdoor use, comprising a oven body, a support frame and a combustion device, wherein the oven body comprises an outer shell, an inner heat dissipation heat spoiler insulation cover, an outer sealed heat insulation cover, at least one layer of heat spoiler, a pizza stone and a heat dissipation furnace mouth, the inner heat dissipation heat spoiler insulation cover and the outer sealed heat insulation cover are sequentially arranged in the outer shell, at least one layer of heat spoiler is arranged at intervals on the inner side of the inner heat dissipation heat spoiler insulation cover, the pizza stone is arranged on the inner side of the bottom of the outer shell, the heat dissipation furnace mouth is arranged directly in front of the outer shell, the support frame is fixedly connected to the oven body and is located below the oven body, and the combustion device is embedded in the oven body and is located on the side opposite to the heat dissipation furnace mouth.

[0005] The space enclosed by the outer shell and the inner heat dissipation and heat turbulence insulation cover serves as a cooking cavity. When making pizza, the raw materials are placed on the pizza stone, the combustion device is responsible for heating, and the heat is discharged from the heat dissipation oven mouth.

[0006] Wherein, each layer of the heat spoiler intersects with the inner layer of heat dissipation heat spoiler heat insulation cover at an obtuse angle.

[0007] Wherein, each layer of the heat spoilers is an arc-shaped plate, and the arched surface of the heat spoilers faces the side of the heat dissipation furnace port.

[0008] The lengths of the heat spoilers at different layers increase sequentially from the combustion device to the heat dissipation furnace port.

[0009] By setting up a heat spoiler, the heat dissipation time can be delayed and the heat can be better concentrated. The heat flow generated by the combustion device forms a backflow when it hits the heat spoiler. In addition, the shape of the arc plate is integrated with the round shape of the pizza, thereby radiating heat to the pizza more evenly.

[0010] There is a cavity between the outer shell, the inner heat dissipation heat turbulence insulation cover and the outer sealed heat insulation cover, and the cavity is connected to the outside through the heat dissipation holes and heat dissipation seams on the heat dissipation furnace mouth.

[0011] The excess heat in the internal cooking cavity can be dissipated from the heat dissipation port and will not be transferred to the outer shell after being isolated by the two layers of cavity, thus preventing the user from being burned.

[0012] Wherein, the support frame includes three furnace feet, and the three furnace feet are arranged in a triangular shape, wherein two of the furnace feet are located side by side on one side of the furnace body close to the heat dissipation furnace port.

[0013] The three furnace legs arranged in a herringbone shape can ensure the stability of the support frame, and at the same time, it is lighter and easier to use than a bracket with four furnace legs.

[0014] Wherein, the combustion device includes a fire baffle, a main burner and a control device, the fire baffle and the main burner are arranged in the outer shell, the fire baffle is located between the main burner and the pizza stone, and the control device is arranged below the outer shell.

[0015] Wherein, the air inlet of the main burner extends to the side of the control device through a pipeline.

[0016] The present invention provides a pizza oven for outdoor use. By arranging a heat spoiler in the oven body, the heat flow generated by the combustion device is refluxed in the oven body, so that the temperature in the oven body can be rapidly increased. At the same time, the arc surface of the heat spoiler is arranged to correspond to the circular shape of the pizza, which can perform heat radiation baking more evenly, thereby improving the baking efficiency of pizza in outdoor environments. Experiments have shown that significant progress has been achieved by adding and adjusting the shape of the heat spoiler, the baking temperature is rapidly increased, and half of the pizza baking time is saved.

DETAILED DESCRIPTION

[0025] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0026] See also Figures 1 to 3 The present invention proposes a pizza oven for outdoor use, comprising a furnace body 1, a support frame 2 and a combustion device 3. The furnace body 1 comprises an outer shell 11, an inner heat dissipation heat spoiler insulation cover 12, an outer sealed heat insulation cover 13, at least one layer of heat spoiler 14, a pizza stone 15 and a heat dissipation furnace mouth 16. The inner heat dissipation heat spoiler insulation cover 12 and the outer sealed heat insulation cover 13 are arranged in sequence in the outer shell 11, at least one layer of heat spoiler 14 is arranged at intervals on the inner side of the inner heat dissipation heat spoiler insulation cover 12, the pizza stone 15 is arranged on the inner side of the bottom of the outer shell 11, and the heat dissipation furnace mouth 16 is arranged directly in front of the outer shell 11, the support frame 2 is fixedly connected to the furnace body 1 and is located below the furnace body 1, and the combustion device 3 is embedded in the furnace body 1 and is located on the side opposite to the heat dissipation furnace mouth 16.

[0027] Each layer of the heat spoiler 14 intersects the inner layer of the heat dissipation heat spoiler heat insulation cover 12 at an obtuse angle.

[0028] Each layer of the heat spoiler 14 is an arc-shaped plate, and the arched surface of the heat spoiler 14 faces the heat dissipation furnace port 16 .

[0029] The lengths of the heat spoilers 14 at different layers increase sequentially from the combustion device 3 to the heat dissipation furnace port 16 .

[0030] A cavity is defined between the outer shell 11 , the inner heat-dissipating heat-turbulent insulation cover 12 and the outer sealed heat-insulating cover 13 , and the cavity is connected to the outside through heat-dissipating holes and heat-dissipating seams on the heat-dissipating furnace opening 16 .

[0031] The support frame 2 includes three furnace legs, which are arranged in a triangular shape, and two of the furnace legs are located side by side on one side of the furnace body 1 close to the heat dissipation furnace port 16 .

[0032] The combustion device 3 includes a fire baffle 31, a main burner 32 and a control device 33. The fire baffle 31 and the main burner 32 are arranged in the outer shell 11, the fire baffle 31 is located between the main burner 32 and the pizza stone 15, and the control device 33 is arranged below the outer shell 11.

[0033] The air inlet of the main burner 32 extends to the side of the control device 33 through a pipeline.

[0034] During use, the pizza ingredients are placed on the pizza stone 15 through the heat dissipation oven port 16. Portable gas is then connected to the air inlet, ignited and heated by the combustion device 3. The control device 33 is adjusted to control the firepower and adjust the temperature. The provision of a heat spoiler 14 can delay the heat dissipation time and thus better concentrate the heat. The heat flow generated by the combustion device 3 forms a backflow when it hits the heat spoiler 14. Furthermore, the shape of the curved plate fits the round shape of the pizza, effectively covering the round edge of the pizza farthest from the heat source. This reduces the number of times the pizza is rotated repeatedly, greatly improving the efficiency of the cycle baking. Experiments have shown that the addition and adjustment of the shape of the heat spoiler 14 have achieved significant improvements, rapidly increasing the baking temperature and saving half the pizza baking time.

[0035] In the outdoor pizza oven of the present invention, there is no specific limit on the number of spoilers provided. Figure 4 , shown is a specific embodiment 2 of the present invention, in which the number of spoilers provided is one layer.

[0036] Furthermore, the present invention is different from the conventional model without heat spoiler (for specific structure and heat flow diagram, please refer to Figure 5 and Figure 6 ) were compared with experimental data:
