Abstract
Description
Technical Field
[0001] This utility model relates to the field of pizza oven technology, specifically to a pizza oven with precise temperature measurement. 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 stones. This method requires purchasing a separate infrared gun and can only provide a single temperature reading, not continuous feedback on the actual temperature of the pizza stones. For some pizza ovens with doors, the door is also required to measure the temperature of the pizza stones, which can lead to a decrease in the temperature of the pizza stones.
[0004] Another method involves installing a mechanical thermometer on the pizza oven to report the temperature of the pizza stone. However, the temperature readings from these thermometers often deviate significantly, typically by ≥±30°C. For some pizza ovens where the pizza stone can rotate, mechanical thermometers are insufficient for direct measurement. Utility Model Content
[0005] The purpose of this invention is to provide a pizza oven that can continuously and accurately detect the temperature of the pizza stone.
[0006] The purpose of this utility model is achieved as follows.
[0007] A pizza oven with precise temperature measurement includes an oven body, a cooking chamber inside the oven body, a pizza stone inside the cooking chamber, an infrared temperature measuring device inside the oven body, a linear temperature measuring channel between the infrared temperature measuring device and the bottom of the pizza stone, the temperature measuring end of the infrared temperature measuring device facing the bottom of the pizza stone through the temperature measuring channel, and a display device on the oven body that displays the temperature of the pizza stone detected by the infrared temperature measuring device.
[0008] Furthermore, the oven body is equipped with a motor and a rotating shaft. The rotating shaft is set to rotate vertically, and the top of the rotating shaft extends into the cooking cavity. A tray rack is provided on the top of the rotating shaft, and the pizza stone sits on the tray rack. The motor and the rotating shaft are connected by a transmission. The motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the pizza stone to rotate through the tray rack. The temperature measuring channel is provided along the axial direction inside the rotating shaft, and the infrared temperature measuring device is set below the rotating shaft.
[0009] The overall structure is more compact, with the temperature measurement channel located at the center of the rotating shaft, making it convenient to detect the temperature at the center of the pizza stone.
[0010] Furthermore, a mounting base is provided below the cooking cavity of the furnace body. A first bearing is provided at the top of the mounting base, and a bushing is provided at the bottom of the mounting base. The rotating shaft is vertically installed in the mounting base and is rotatably connected to the first bearing and the bushing. The hollow interior of the rotating shaft forms the temperature measuring channel. A motor is fixed on one side of the mounting base by a first bracket, so that the motor is horizontally installed on one side of the rotating shaft. A first bevel gear is provided on the outer circumference of the rotating shaft, and a second bevel gear is rotatably installed in the mounting base by a second bearing. The first bevel gear and the second bevel gear mesh and drive each other. The motor drives the second bevel gear to drive the first bevel gear to rotate, and the first bevel gear drives the rotating shaft to rotate synchronously.
[0011] The installation positions of the motor and infrared temperature measuring device are designed to avoid interference from movement, ensuring accurate and stable temperature measurement by the infrared temperature measuring device.
[0012] Furthermore, the infrared temperature measuring device includes a mounting shell and an infrared temperature sensor. The mounting shell is fixed to the bottom surface of the mounting base by a second bracket, and the infrared temperature sensor is fixed inside the mounting shell. The top of the mounting shell is provided with a second through hole corresponding to the temperature measuring end of the infrared temperature sensor, and the temperature measuring channel and the second through hole are aligned vertically.
[0013] Infrared temperature sensors are simple and easy to install, and the housing protects them from damage.
[0014] Furthermore, the tray frame is provided with a first through hole, and the top of the rotating shaft extends upward from the first through hole. The first through hole prevents the tray frame from blocking the infrared temperature sensor from measuring the temperature of the pizza stone.
[0015] Furthermore, the pizza stone has a concave section at the center of its bottom surface, with the bottom of the concave section forming a temperature measuring point. The top of the temperature measuring channel faces this measuring point. Since the measuring point is close to the center of the pizza stone's top surface, the obtained temperature is essentially the same as the temperature of the pizza's bottom surface. This results in more reliable temperature data.
[0016] This invention features a simple and reliable design, enabling continuous and accurate temperature measurement of pizza stones using an infrared thermometer. The motor and infrared thermometer are strategically positioned to avoid interference from movement, ensuring accurate and stable temperature measurement. The overall structure is more compact, with the temperature measurement channel located at the center of the rotating shaft for convenient temperature measurement at the center of the pizza stone. The infrared temperature sensor is easy to install, and the housing protects it from damage. Attached Figure Description

Preferably, an air temperature sensor 14 is also provided inside the oven body 1, with its temperature measuring end installed inside the cooking cavity 11, above the pizza stone 12. The air temperature sensor 14 is electrically connected to the detection circuit board 61. The air temperature sensor 14 detects the temperature of the cooking cavity 11. The air temperature sensor 14 is prior art, and its specific structure will not be described in detail.
[0037] The furnace body 1 has a mounting bracket 7 and a display device 8 at its bottom. The mounting bracket 7 and the display device 8 are detachably connected. Specifically, the mounting bracket 7 is inclined forward and downward as a whole.
