Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas-fired pizza oven technology, specifically to a uniform temperature pizza oven. Background Technology
[0002] Gas-fired pizza ovens on the market typically have a pizza stone and a burner inside. The burner is located on the side or behind the pizza stone, and the front of the oven has an opening for the pizza to enter and exit. Because heat is lost quickly at the opening, there is a large temperature difference between the end of the pizza stone near the opening and the end away from the opening, resulting in uneven heating of the pizza.
[0003] When baking pizza, users need to repeatedly remove and rotate the pizza before placing it back on the pizza stone to ensure even heating. This method is difficult and inconvenient, making it extremely challenging for beginners.
[0004] Therefore, some gas-fired pizza ovens incorporate a motor-driven rotating mechanism within the oven body. This mechanism rotates the pizza stone, ensuring even heating of the pizza on the stone. However, the motor and rotating mechanism significantly increase the cost of gas-fired pizza ovens, reducing their market competitiveness. Utility Model Content
[0005] The purpose of this invention is to provide a cost-effective, uniformly heated pizza oven.
[0006] The purpose of this utility model is achieved as follows.
[0007] A uniform temperature pizza oven includes an oven body and a gas burner. The oven body has a cooking chamber with a pizza stone at the bottom. The oven body has an inlet and outlet connecting to the cooking chamber on one side. The inner end of the gas burner is located on the side of the cooking chamber away from the inlet and outlet, and the outer end of the gas burner extends towards the inlet and outlet. The gas burner has a plurality of flame holes. The density of the flame holes at the outer end of the gas burner is greater than the density of the flame holes at the inner end of the gas burner and / or the diameter of the flame holes at the outer end of the gas burner is greater than the diameter of the flame holes at the inner end of the gas burner, so that the flame intensity at the outer end of the gas burner is greater than the flame intensity at the inner end of the gas burner.
[0008] Furthermore, the gas burner head is provided with a first flame zone, a second flame zone and a third flame zone. A row of flame holes is arranged on the inner section of the gas burner head to form the first flame zone, two rows of flame holes are arranged on the middle section of the gas burner head to form the second flame zone, and three rows of flame holes are arranged on the outer section of the gas burner head to form the third flame zone.
[0009] The flame intensity of the first, second, and third flame zones increases sequentially, making the temperature from the end of the cooking cavity to the inlet and outlet relatively uniform, thus achieving even heating of the pizza.
[0010] Furthermore, the apertures of the flame holes in the first, second, and third flame zones are the same.
[0011] Convenient for manufacturing gas burner heads.
[0012] Furthermore, the gas burner head includes a base pipe, a vertical pipe, and a horizontal pipe. The base pipe is located on the side of the cooking chamber away from the inlet and outlet. The vertical pipe extends upward from both ends of the base pipe. The horizontal pipe extends from the top of the vertical pipe from the inner end of the cooking chamber to the inlet and outlet end. The horizontal pipe is suspended above the pizza stone.
[0013] Furthermore, the horizontal tube is provided with a first flame zone, a second flame zone and a third flame zone. A row of flame holes extending from the first flame zone extends through the vertical tube to the base tube. The flame holes of the horizontal tube are all set downwards, and the flame holes of the vertical tube and the base tube are set towards the pizza stone.
[0014] The horizontal tube heats the pizza downwards, while the vertical tube and base tube heat the pizza outwards.
[0015] Furthermore, the cross-section of the gas burner head is in the shape of an inverted isosceles trapezoid, with the flame holes provided on both sides of the horizontal pipe, the flame holes provided on the inward-facing sides of the two vertical pipes, and the flame holes provided on the upward-facing side of the base pipe.
[0016] It makes it easy to ignite the gas burner head with an electric sparkler.
[0017] Compared with existing technologies, this invention reduces the interference of the pizza inlet / outlet on the pizza temperature on the pizza block by setting different numbers or diameters of flame holes at different positions of the gas burner head, thus achieving uniform pizza heating. It eliminates the need for users to flip the pizza multiple times, simplifying the baking process and making it suitable for beginners. The overall structure does not include a rotating mechanism, resulting in lower costs and greater market competitiveness. Attached Figure Description

[0020] Figure 5 This is a schematic diagram of the gas burner head burning in the cooking chamber in Example 1. Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Example 1, see Figure 1-5As shown, a uniform temperature pizza oven includes an oven body 1 and a combustion system. In this embodiment, the oven body 1 includes a base 11 and an upper shell 12. A cooking chamber 10 is formed between the top surface of the base 11 and the upper shell 12. A pizza stone 13 is provided on the top of the base 11, and an inlet / outlet 14 communicating with the cooking chamber 10 is provided on one side of the upper shell 12. The combustion system includes a gas burner 2, a thermocouple 3, an ignition needle 4, a control valve body 5, and a control knob 6. The gas burner 2, thermocouple 3, and ignition needle 4 are fixed to the top surface of the base 11. The control valve body 5 is disposed inside the base 11, and the control knob 6 is disposed on the outer surface of the base 11. The control knob 6 controls the gas flow rate of the gas burner 2 through the control valve body 5.
[0023] In this embodiment, the inner end of the gas burner head 2 is located on the side of the cooking cavity 10 away from the inlet / outlet 14, and the outer end of the gas burner head 2 extends towards the inlet / outlet 14. The gas burner head 2 is provided with a plurality of flame holes 20, and the density of the flame holes 20 at the outer end of the gas burner head 2 is greater than the density of the flame holes 20 at the inner end of the gas burner head 2. Specifically, the gas burner head 2 is provided with a first flame zone 21, a second flame zone 22, and a third flame zone 23. One row of flame holes 20 is located on the inner section of the gas burner head 2 to form the first flame zone 21, two rows of flame holes 20 are located on the middle section of the gas burner head 2 to form the second flame zone 22, and three rows of flame holes 20 are located on the outer section of the gas burner head 2 to form the third flame zone 23. Preferably, the flame holes 20 in the first flame zone 21, the second flame zone 22, and the third flame zone 23 have the same aperture. The flame hole density refers to the number of flame holes 20 within a certain area.
[0024] See Figure 3-5 As shown, the gas burner head 2 has an inverted isosceles trapezoidal cross-section. The gas burner head 2 includes a base pipe 7, vertical pipes 8, and horizontal pipes 9. The base pipe 7 is located on the side of the cooking chamber 10 away from the inlet / outlet 14. The vertical pipes 8 extend upwards from both ends of the base pipe 7. The horizontal pipe 9 extends from the top of the vertical pipes 8 from the inner end of the cooking chamber 10 towards the inlet / outlet 14. The horizontal pipe 9 is suspended above the pizza stone 13. The horizontal pipe 9 has flame holes 20 on both sides and includes a first flame zone 21, a second flame zone 22, and a third flame zone 23. The flame holes 20 are located on the inward-facing sides of the two vertical pipes 8. A row of flame holes 20 extending from the first flame zone 21 extends from the vertical pipes 8 to the base pipe 7. The flame holes 20 are located on the upward-facing side of the base pipe 7. The flame holes 20 of the horizontal pipe 9 are generally downward-facing, while the flame holes 20 of the vertical pipes 8 and the base pipe 7 are oriented towards the pizza stone 13. A thermocouple 3 and an ignition needle 4 are located on one side of the base pipe 7.
[0025] In this invention, the flame intensity at the outer end of the gas burner 2 is greater than the flame intensity at the inner end of the gas burner 2. That is, the temperature of the pizza stone 13 near the inlet / outlet 14 is higher than the temperature of the pizza stone 13 away from the inlet / outlet 14. Because the inlet / outlet 14 causes the pizza stone 13 to lose some heat, the overall temperature of the pizza stone 13 is relatively uniform, and the pizza on the pizza stone 13 is heated relatively uniformly.
[0026] Example 2 differs from Example 1 in that the diameter of the outer burner hole 20 of the gas burner head 2 is larger than that of the inner burner hole 20, resulting in a greater flame intensity at the outer end of the gas burner head 2 compared to the inner end. Of course, based on the volume of the uniform-temperature pizza oven body 1, the number and diameter of the outer burner hole 20 of the gas burner head 2 can both be greater than those at the inner end.
