Description

Technical Field

[0001] This utility model relates to the field of pizza oven technology, specifically to a temperature measuring structure for a rotary pizza oven. Background Technology

[0002] Some pizza ovens on the market have a drive device inside the oven to rotate the pizza stone in order to ensure that the pizza on the pizza stone is heated evenly.

[0003] When baking pizza, consumers need to monitor the actual temperature of the pizza stone to accurately determine if the bottom of the pizza is crispy. Therefore, real-time and accurate temperature measurement of the pizza stone is necessary. However, because the pizza stone is rotating, the wire of the temperature probe twists and turns with the rotation, making installation impossible and preventing accurate measurement of the real-time temperature of a rotating pizza stone. Currently, there is no reliable solution on the market for measuring the temperature of a rotating pizza stone. Therefore, the displayed pizza stone temperature can only be calculated by fixing the temperature probe inside the oven cavity and estimating the real-time temperature of the pizza stone based on the temperature difference between the oven cavity and the pizza stone. This results in a simulated value, not the actual temperature, leading to inconsistent flavor and texture in the pizza. Utility Model Content

[0004] The purpose of this invention is to provide a temperature measuring structure for a rotary pizza oven that can accurately and in real-time detect the temperature of the rotating pizza stone.

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

[0006] A temperature measuring structure for a rotating pizza oven includes a pizza stone disposed in a cooking chamber and a drive device disposed in the oven body. The output end of the drive device extends into the cooking chamber and is provided with a tray. The pizza stone sits on the tray. The drive device drives the pizza stone to rotate through the tray. A temperature probe is provided on the tray. The temperature detection part at the top of the temperature probe abuts against the pizza stone. An elastic conductive part is provided at the bottom of the temperature probe. A temperature sensing repeater is provided at the bottom of the cooking chamber corresponding to the bottom of the temperature probe. The elastic conductive part and the temperature sensing repeater make sliding contact and conduct electricity. The wiring terminal of the temperature sensing repeater extends into the oven body.

[0007] Furthermore, the elastic conductive part includes a first elastic pin and a second elastic pin, and the temperature sensing repeater includes a first annular contact slider and a second contact slider. The first elastic pin and the first contact slider make sliding contact and conduct electricity, and the second elastic pin and the second contact slider also make sliding contact and conduct electricity. During the rotation of the pizza stone, the temperature probe and the temperature sensing repeater maintain good conductive contact.

[0008] Furthermore, the temperature sensing repeater has a first annular groove and a second annular groove on its top. The first annular groove and the second annular groove are coaxially arranged, and the first annular groove is located inside the second annular groove. A first contact slider is located on the bottom surface of the first annular groove, and a first elastic pin is inserted into the first annular groove. A second contact slider is located on the bottom surface of the second annular groove, and a second elastic pin is inserted into the second annular groove.

[0009] Furthermore, a circuit board is installed inside the furnace. The terminals of the temperature sensor repeater are electrically connected to the circuit board, and the temperature of the pizza stone detected by the temperature probe is fed back to the circuit board via an electrical signal.

[0010] Furthermore, the tray has a hollow section near the center, and a fixed arm is provided radially inside the hollow section. The fixed arm has a temperature measuring hole, and a temperature probe is set on the bottom surface of the fixed arm. The temperature detection part at the top of the temperature probe passes upward through the temperature measuring hole and abuts against the pizza stone.

[0011] Furthermore, the radial cross-section of the fixed arm is horizontally L-shaped, and the temperature probe is set on the bottom surface of the horizontal part of the fixed arm. The horizontal part of the fixed arm is provided with the temperature measuring hole, and the bottom surface of the horizontal part of the fixed arm and the outer side of the vertical part form a receiving groove for the temperature probe.

[0012] Furthermore, the bottom of the cooking cavity is composed of a base plate, which has a first groove. The bottom surface of the first groove has a through hole. The output end of the drive device passes through the through hole and is connected and fixed to the tray in the first groove. The bottom surface of the first groove has an annular protrusion around the through hole. The annular protrusion and the base plate form a second groove. The temperature sensing repeater is in the shape of a ring and is fixed to the bottom surface of the second groove.

[0013] This invention features a simple and reliable design. The temperature probe and the pizza stone remain relatively stationary, allowing the temperature probe to directly and in real-time measure the temperature of the pizza stone, resulting in accurate and reliable temperature data. The temperature probe and the temperature sensing repeater have a sliding contact that conducts electricity, facilitating the transmission of temperature data through the repeater and preventing motion interference with the rotating pizza stone.

The output end of the drive device 6 passes through the through hole 52 and is connected and fixed to the tray 2 in the first groove 51. The bottom surface of the first groove 51 has an annular protrusion 53 around the through hole 52, and the annular protrusion 53 and the base plate 5 form a second groove 54. The drive device 6 includes a motor 61 and a rotating shaft. The motor shaft of the motor 61 is connected to the bottom of the rotating shaft 62. The top of the rotating shaft 62 extends into the first groove 51 through the through hole 52. The top of the rotating shaft 62 is provided with a fixing plate 63, which is connected and fixed to the tray 2. The motor 61 drives the pizza stone 1 to rotate through the rotating shaft 62, the fixing plate 63, and the tray 2.

[0021] A temperature probe 3 is provided on the tray 2. The temperature sensing part 31 at the top of the temperature probe 3 abuts against the pizza stone 1. The bottom of the temperature probe 3 is provided with an elastic conductive part 32, which includes a first elastic pin 33 and a second elastic pin 34. Specifically, a hollow part 21 is provided near the center of the tray 2. A fixing arm 22 is provided radially inside the hollow part. The radial cross-section of the fixing arm 22 is horizontally L-shaped. A temperature measuring hole 23 is provided on the horizontal part of the fixing arm 22. The bottom surface of the horizontal part and the outer side of the vertical part of the fixing arm 22 form a receiving groove 24 for the temperature probe 3. The temperature probe 3 is placed on the bottom surface of the horizontal part of the fixing arm 22. The temperature sensing part 31 at the top of the temperature probe 3 passes upward through the temperature measuring hole 23 and abuts against the pizza stone 1. In this embodiment, the temperature probe 3 is a K-type thermocouple, and the elastic conductive part 32 (i.e., the first elastic pin 33 and the second elastic pin 34) is a spring pin installed on the terminal of the temperature probe 3. The K-type thermocouple and the spring pin are both existing technologies and can be purchased from the market.

[0022] A temperature sensing repeater 4 is provided at the bottom of the cooking cavity corresponding to the bottom of the temperature probe 3. The temperature sensing repeater 4 is annular and fixed to the bottom surface of the second groove 54. The temperature sensing repeater 4 includes an annular first contact slider 41 and a second contact slider 42. The top of the temperature sensing repeater 4 is provided with a first annular groove 43 and a second annular groove 44, which are coaxially arranged, with the first annular groove 43 located within the second annular groove 44. The first contact slider 41 is located on the bottom surface of the first annular groove 43.

[0024] During cooking, the pizza stone 1, tray 2, and temperature probe 3 rotate synchronously, meaning the temperature probe 3 and pizza stone 1 remain relatively stationary. The temperature sensing part 31 of the temperature probe 3 remains in contact with the pizza stone 1, thereby achieving accurate detection of the actual temperature of the pizza stone 1. The temperature probe 3 rotates with the tray 2, and the first elastic pin 33 rotates within the first annular groove 43, making sliding contact with the first contact slider 41 for electrical conduction. The second elastic pin 34 rotates within the second annular groove 44, making sliding contact with the second contact slider 42 for electrical conduction. This achieves sliding contact electrical conduction between the elastic conductive part 32 and the temperature sensing repeater 4. The temperature sensing repeater 4 transmits the temperature data from the temperature probe 3 to the circuit board, thereby displaying the real-time temperature of the pizza stone 1.
