Description

Technical Field

[0001] This utility model relates to the field of electric pizza oven technology, and in particular to a temperature measuring structure for an electric pizza oven. Background Technology

[0002] Some pizza ovens on the market require the pizza stone to be preheated to a certain temperature before placing the pizza on it for baking. Different types of pizza have different preheating temperature requirements for the pizza stone. If the pizza stone temperature is too high or too low, it will affect the baking effect of the pizza, resulting in a poorly baked bottom.

[0003] Currently, there are two main methods for detecting the temperature of pizza stones inside a pizza oven. One method uses a dedicated infrared gun to test the pizza stone. This method requires purchasing a separate infrared gun and can only provide a single measurement temperature, not a continuous reading of the actual temperature of the pizza stone. For pizza ovens with doors, the door is also required to measure the temperature of the pizza stone, which can lead to a drop in the pizza stone temperature. The other method involves installing a mechanical thermometer on the pizza oven to report the pizza stone temperature. However, the temperature readings from these thermometers often have a large deviation, typically ≥ ±30°C. Utility Model Content

[0004] The purpose of this invention is to provide a temperature measuring structure for an electric pizza oven that makes it easier to remove and place pizza stones without damaging the temperature detection device.

[0005] The purpose of this utility model is achieved as follows.

[0006] A temperature measuring structure for an electric pizza oven includes an oven body and a cooking chamber disposed within the oven body. A pizza stone is placed at the bottom of the cooking chamber. A temperature detection device is disposed within the oven body, with its sensing end extending into the cooking chamber. The sensing end is vertically extendable and has an upward tendency, with its top facing the center of the pizza stone. At least one guide groove is provided on the bottom surface of the pizza stone near its center. The outer end of the guide groove has an inlet on the side of the pizza stone, and the inner end of the guide groove is flush with the bottom surface of the pizza stone. The pizza stone is pushed into the cooking chamber and placed therein. The sensing end is aligned with the center of the bottom surface of the pizza stone via the guide groove, and the sensing end remains in contact with the bottom surface of the pizza stone.

[0007] Furthermore, a heat insulation cavity is provided at the bottom of the cooking cavity, and a temperature detection device is located inside the heat insulation cavity. The temperature detection device includes a temperature sensor, a heat insulation cover, a spring, and a limiting cylinder. A first clearance hole is provided at the top of the heat insulation cavity, which communicates with the cooking cavity. The heat insulation cover is located at the bottom of the heat insulation cavity. The temperature sensor, the limiting cylinder, and the spring are located inside the heat insulation cover. A second clearance hole is provided at the top of the heat insulation cover, and a third clearance hole is provided at the bottom of the heat insulation cover. The bottom of the spring abuts against the bottom of the heat insulation cavity or the bottom of the heat insulation cover, and the top of the spring abuts against the limiting cylinder. The spring force pushes the limiting cylinder to lift the temperature sensor upward until the temperature sensor abuts against the top of the heat insulation cover. The temperature sensing end of the temperature sensor extends upward through the second clearance hole and the first clearance hole and then into the cooking cavity.

[0008] Furthermore, a circular limiting plate is provided at the top of the limiting cylinder. The diameter of the limiting plate is similar to the inner diameter of the heat insulation cover. The limiting plate moves axially along the heat insulation cover. The wiring terminal of the temperature sensor extends into the limiting cylinder through the limiting plate. The top of the spring is sleeved outside the limiting cylinder and abuts against the top of the limiting plate.

[0009] Furthermore, the heat insulation cover has a mounting plate at the bottom, one end of which is bent upward to form a positioning block. The mounting plate has the third clearance hole. The heat insulation cover has a connecting plate on the outer periphery of the bottom, and the connecting plate has a first positioning hole. The positioning block of the mounting plate passes through the first positioning hole. The bottom surface of the connecting plate abuts against the mounting plate and is connected and fixed by the first fastener. The bottom of the spring abuts against the mounting plate.

[0010] Furthermore, the bottom of the heat insulation cavity is provided with a mounting hole and a second positioning hole. The top of the heat insulation cover passes through the mounting hole, and the positioning block passing through the first positioning hole aligns with the second positioning hole. The connecting plate and the bottom surface of the heat insulation cavity abut against each other and are connected and fixed by a second fastener.

[0011] Furthermore, the width of the guide groove gradually narrows from the outer end to the inner end, and the bottom surface of the guide groove is a guide slope.

[0012] This invention ensures that the pizza stones remain in contact with the temperature sensing end of the temperature detection device after being placed or removed, guaranteeing accurate temperature measurement. The guide groove prevents damage to the temperature sensing end of the device during the placement of the pizza stones. The integrated installation of the temperature detection device facilitates pre-assembly before installation into the oven body, which is beneficial for maintenance or replacement. The design of the positioning block, first positioning hole, and second positioning hole makes positioning and assembly easy. Attached Figure Description

The bottom of the spring 6 abuts against the bottom of the heat insulation cavity 12 or the bottom of the heat insulation cover 5, and the top of the spring 6 abuts against the limiting cylinder 7. The elastic force of the spring 6 pushes the limiting cylinder 7 to lift the temperature sensor 4 upward until the temperature sensor 4 abuts against the top of the heat insulation cover 5. The temperature sensing end 30 of the temperature sensor 4 passes upward through the second clearance hole 50 and the first clearance hole 15 and extends into the cooking cavity 11.

[0019] Specifically, the top of the limiting cylinder 7 is provided with a circular limiting plate 71, the diameter of which is similar to the inner diameter of the heat insulation cover 5. The limiting plate 71 moves axially along the heat insulation cover 5. The wiring terminal of the temperature sensor 4 extends into the limiting cylinder 7 through the limiting plate 71.

The bottom of the heat insulation cover 5 is provided with a mounting plate 54, one end of which is bent upward to form a positioning block 55. The mounting plate 54 is provided with the third clearance hole 56.

The positioning block 55 of the mounting plate 54 passes through the first positioning hole 53. The bottom surface of the connecting plate 52 abuts against the mounting plate 54 and is connected and fixed by a first fastener (such as a bolt). The bottom of the spring 6 abuts against the mounting plate 54. The heat insulation cover 5 and the limiting plate 71 connect and fix the temperature sensor 4, the spring 6, and the limiting cylinder 7, realizing the pre-assembly of the temperature sensor 4.

[0020] The bottom of the heat insulation cavity 12 is provided with a mounting hole 13 and a second positioning hole 14. The top of the heat insulation cover 5 passes through the mounting hole 13, and the positioning block 55, which passes through the first positioning hole 53, aligns and passes through the second positioning hole 14. The connecting plate 52 and the bottom surface of the heat insulation cavity 12 abut against each other and are connected and fixed by a second fastener (such as a bolt). That is, the temperature sensor 4 is installed in the heat insulation cavity 12.

[0021] Pizza stone 2 is pushed into cooking cavity 11 and placed. Temperature sensing end 30 is aligned with the center of the bottom surface of pizza stone 2 via guide groove 20. Temperature sensor 4 moves downward and compresses spring 6. Limiting cylinder 7 guides temperature sensor 4 to move within heat insulation cover 5. The elasticity of spring 6 keeps temperature sensing end 30 in contact with the bottom surface of pizza stone 2.
