[0003] While most temperature sensors in steam ovens on the market can achieve rapid temperature sensing, they generally suffer from poor heat dissipation. Poor heat dissipation causes the sensor to require a prolonged cooling time after each measurement, extending the interval between uses and severely impacting the continuous operating efficiency of the steam oven. Furthermore, the temperature buildup caused by insufficient heat dissipation can lead to a significant discrepancy between the temperature displayed on the control panel and the actual temperature, making it difficult for users to accurately determine the cooking temperature and consequently affecting the quality of the food.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] Reference Figures 1-5A temperature sensor for a steam oven includes an aluminum sensing element 1. The aluminum sensing element 1, as the core component for temperature sensing, is made of aluminum, which has excellent thermal conductivity, and can quickly detect temperature changes inside the steam oven. A silicone sealant 2 is fixedly connected to the left side of the aluminum sensing element 1. The silicone sealant 2 has good sealing and high-temperature resistance, effectively preventing external moisture and impurities from entering and ensuring the stable operation of the internal components of the sensor. An aluminum screw 3 is threadedly connected to the right side of the aluminum sensing element 1. The aluminum screw 3 not only serves as a fixed connection but also participates in the heat conduction process. The vertical cross-section of the aluminum screw 3 is T-shaped, and a through hole 4 is provided on the aluminum screw 3. A ceramic cap 8 is provided inside the aluminum sensing element 1. The adjacent side of the ceramic cap 8 and the aluminum screw 3 are elastically connected by a connecting spring 7. The left side of the ceramic cap 8 extends into the silicone sealant 2. A ceramic baffle 9 is provided inside the ceramic cap 8. Two resistor strips 5 are fixedly connected on the right side. The resistor strips 5 are made of special resistive material, and their resistance value changes sensitively with temperature changes, thereby converting the temperature signal into an electrical signal. The two resistor strips 5 extend to the outside through the through hole 4 on the right side and are fixedly connected to the connector 6. The connector 6 is used to connect to the control system of the steam oven, and transmit the electrical signal generated by the resistor strips 5 to the control system to realize temperature monitoring and feedback. The outer surface of the aluminum screw 3 is knurled, which increases the surface friction of the aluminum screw 3, making it easy to install and disassemble. The edges of the aluminum screw 3 are all chamfered at a 45-degree angle. The aluminum sensor 1 includes an aluminum cylinder, and multiple aluminum rings are fixedly connected to the outer wall of the aluminum cylinder. The multiple aluminum rings are distributed in a linear array. These aluminum rings further increase the heat dissipation area, accelerate heat dissipation, and enable the sensor to respond more quickly to the temperature changes of the steam oven.

[0040] Reference Figures 6-14The present invention also proposes a processing system for a steam oven temperature sensor, including a worktable 10. A vertical plate 12 and two fixed plates 13 are fixedly connected to the upper end of the worktable 10. A second rotating rod 19 is rotatably connected to the adjacent sides of the two fixed plates 13. A rectangular block is fixedly connected to the second rotating rod 19. Processing frame assemblies are provided on the top, bottom, left, and right sides of the rectangular block. The processing frame assemblies are used to clamp and fix the aluminum screws 3 to be processed, and cooperate with other components to complete the processing operation. The processing frame assembly includes a cylinder 50 rotatably connected to the rectangular block. The cylinder 50 provides a sliding track for the sliding rod 44. Simultaneously, under the action of the rotating component, the aluminum screw 3 can be rotated to achieve processing steps such as knurling. A sliding rod 44 is slidably connected inside the cylinder 50. The sliding rod 44 is elastically connected to the inner wall of the cylinder 50 through a first spring 53. The first spring 53 provides a restoring force for the sliding rod 44, and the strength of the first spring 53 is relatively large. The rotation of the cylinder 50 can drive the sliding rod 44 to rotate through the first spring 53. A disk 45 is fixedly connected to the side of the sliding rod 44 away from the rectangular block. A rectangular rod 46 is fixedly connected to the disk 45. The four sides of the rectangular rod 46 contact the through hole 4, and the rectangular rod... 46 is not square to prevent relative rotation during the machining of aluminum screw 3. A sleeve rod 47 is fixedly connected to the side of the rectangular rod 46 away from the disc 45. The sleeve rod 47 is equipped with a limiting component. A slotting component is provided on the left side of the two vertical plates 12. Four rotating components are provided on the rectangular block. The rotating components are used to drive the aluminum screw 3 to rotate and perform knurling on the surface of the aluminum screw 3. A second motor 18 is installed on the mounting plate 11 located on the front side. An incomplete gear 30 is fixedly connected to the end of the output shaft of the second motor 18. The front side of the second rotating rod 19 passes through the mounting plate 11 and is fixedly connected to a first tooth. The wheel 20 and the incomplete gear 30 first mesh with the first gear 20 to adjust the position of the four processing frame components, and then mesh with the third gear to feed the material. The grooving assembly includes two fixed plates 13 fixedly connected to the left side of the two mounting plates 11. The adjacent sides of the two fixed plates 13 are rotatably connected to the first rotating rod 15. The first rotating rod 15 is fixedly connected to the milling cutter 16, which can ensure that the required groove shape is processed on the surface of the aluminum screw 3. The first motor 14 is installed on the fixed plate 13 located on the front side. The first motor 14 is fixedly connected to the end of the output shaft of the first rotating rod 15.

[0041] The rotating assembly includes a strip box 31 fixedly connected to a rectangular block. A first pneumatic rod 48 is fixedly connected to the rear inner wall of the strip box 31. A moving block 49 is fixedly connected to the telescopic end of the first pneumatic rod 48. A rack 52 is fixedly connected to the front side of the moving block 49. A second gear 51 meshing with the rack 52 is provided on the cylinder 50. A one-way bearing is provided between the second gear 51 and the cylinder 50. A displacement sensor 60 is fixedly connected to the side of the strip box 31 away from the rectangular block. The displacement sensor 60 is used to monitor the movement of the disc 45 and is equipped with a controller. When the disc 45 moves to the farthest position and the closest position, the controller will control the first pneumatic rod 48 to contract and extend once. The one-way bearing allows the rack 52 to move backward and drive the cylinder 50 to rotate 20 degrees through the second gear 51. When the rack 52 moves forward, the rotation of the second gear 51 will not drive the cylinder 50 to rotate.

[0042] The limiting assembly includes multiple limiting grooves on the outside of the sleeve rod 47. Each limiting groove has an electromagnet 56 inside on the side near the axis of the sleeve rod 47. Each limiting groove has a limiting block 54 slidably connected. Each limiting block 54 is elastically connected to the adjacent side of the electromagnet 56 by a second spring 55. Multiple second conductive blocks 43 are fixedly connected to the outer wall of the second rotating rod 19. An arc-shaped conductive sheet 59 is fixedly connected to the mounting plate 11 on the front side. The positive and negative poles of the power supply are electrically connected to the two ends of the arc-shaped conductive sheet 59 by wires. The two ends of the four second conductive blocks 43 are electrically connected to the two ends of the four corresponding electromagnets 56 by wires. When the second conductive block 43 contacts the arc-shaped conductive sheet 59, the multiple electromagnets 56 will be energized, attracting the limiting block 54 into the limiting groove. The aluminum screw 3 will automatically slide down onto the worktable 10.

[0043] The assembly also includes a reciprocating motion component, which comprises a rectangular box 40 mounted on a rear mounting plate 11. A second pneumatic rod 57 is fixedly connected to the bottom inner part of the rectangular box 40. A piston plate 58 is fixedly connected to the telescopic end of the second pneumatic rod 57. The piston plate 58 is slidably and sealingly connected to the inner wall of the rectangular box 40. A rotary joint 38 is provided on the rear mounting plate 11. An airflow channel is provided inside the second rotating rod 19. The inner wall space of multiple cylinders 50 is connected to the airflow channel through air holes. Each air hole is equipped with a solenoid valve. The airflow channel is connected to the front side of the rotary joint 38, and the rear side of the rotary joint 38 is connected to the rectangular box 40. The top space of the shaped box 40 is connected through the connecting pipe 39. Four first conductive blocks 28 are fixedly connected to the outer wall of the second rotating rod 19. Two contact pieces 29 are fixedly connected to the mounting plate 11 located on the rear side. A power supply is provided on the workbench 10. The positive and negative terminals of the power supply are electrically connected to the two contact pieces 29 through wires. Each first conductive block 28 is electrically connected to the two ends of the corresponding solenoid valve through wires. When the first conductive block 28 rotates to the left, it will cause the solenoid valve in the corresponding air hole to be energized and connected. At this time, the up and down movement of the piston plate 58 will cause the aluminum screw 3 on the left to move left and right, thereby performing knurling on the surface of the aluminum screw 3.

[0044] The vertical plate 12 has an automatic feeding assembly on its left side. This assembly includes a fixed block fixedly connected to the left side of the vertical plate 12. A placement platform 27 is fixedly connected to the left side of the fixed block. Two support blocks are fixedly connected to the upper end of the placement platform 27, and a placement box 23 is fixedly connected to the upper end of both support blocks. A first threaded rod 35 is rotatably connected through the vertical plate 12. A first threaded sleeve 25 is threadedly connected to the first threaded rod 35. A push plate 26 is fixedly connected to the left side of the first threaded sleeve 25. A second mounting block is fixedly connected to the front side of the vertical plate 12. A transmission rod 21 is rotatably connected through the second mounting block. A short rod 61 is rotatably connected to the mounting plate 11 located on the front side. The short rod 61 is equipped with… There is a third gear, and the short rod 61 and the transmission rod 21 are both equipped with second bevel gears 42 that mesh with each other. The transmission rod 21 and the first threaded rod 35 are connected by a second transmission assembly 22. The second transmission assembly 22 includes second sprockets set on the transmission rod 21 and the first threaded rod 35. The two second sprockets are connected by a second chain. An arc-shaped baffle 24 is fixedly connected to the right side of the push plate 26. The arc-shaped baffle 24 ensures that the aluminum screw 3 will not fall down each time the push plate 26 moves, and the aluminum screw 3 in the placement box 23 will fall down after the push plate 26 is reset. The arc-shaped baffle 24 passes through the vertical plate 12 and is slidably connected to the vertical plate 12. It can also provide guidance for the movement of the push plate 26.

[0045] The workbench 10 has a grinding assembly at its upper end. The grinding assembly includes two telescopic rods 34 fixedly connected to the upper end of the workbench 10. The telescopic ends of the two telescopic rods 34 are fixedly connected to a fixed plate 32. The upper end of the fixed plate 32 is fixedly connected to a plurality of grinding tools 33. The shape and number of grinding tools 33 are consistent with the number and shape of the knurling on the surface of the aluminum screw 3. The lower end of the fixed plate 32 is fixedly connected to a second threaded sleeve 37. The second threaded sleeve 37 is internally threaded with a second threaded rod 36. The lower end of the second threaded rod 36 passes through the workbench 10. The lower end of the workbench 10 is fixedly connected to a first mounting block. A crossbar is rotatably connected through the first mounting block. Both the crossbar and the second threaded rod 36 are provided with first bevel gears 41. The crossbar and the first rotating rod 15 are connected by a first transmission assembly 17. The first transmission assembly 17 includes a first sprocket set on the crossbar and the first rotating rod 15. The two first sprockets are connected by a first chain.

[0046] The functional principle of this invention can be explained through the following operation: When the temperature inside the steam oven changes, the aluminum sensor 1 quickly absorbs heat through multiple aluminum rings on its surface and transfers the temperature to the internal ceramic cap 8. The ceramic baffle 9 inside the ceramic cap 8 isolates external interference, ensuring that the resistor strip 5 only responds to temperature changes. The resistance value of the resistor strip 5 changes with temperature, and this change is converted into an electrical signal through the connector 6 and transmitted to the steam oven control system, achieving accurate temperature measurement. Furthermore, when the oven temperature decreases, the aluminum rings also cause the sensor temperature to drop rapidly, allowing the sensor to be quickly reused.

[0047] In the production process of temperature sensors, the semi-finished aluminum screws 3 are first stacked vertically in the placement box 23. The end of the aluminum screw 3 with the smaller outer diameter is located on the left side, the end with the larger outer diameter is located on the right side, and the bottom aluminum screw 3 is located on the placement platform 27.

[0048] When production starts, the second motor 18 operates. Initially, the incomplete gear 30 meshes with the first gear 20. The operation of the second motor 18 drives the second rotating rod 19 to rotate 90 degrees, causing the four processing rack assemblies to rotate 90 degrees in a circular motion. Subsequently, the incomplete gear 30 meshes with the third gear, driving the first threaded rod 35 to rotate. This causes the first threaded sleeve 25 to drive the push plate 26 to move left and then right, pushing the aluminum screw 3 on the placement table 27 onto the processing rack assembly. During the pushing process, because the right side of the limiting block 54 is curved, it enters the limiting groove. When the aluminum screw 3 contacts the disc 45, under the action of the second spring 55, the limiting block 54 moves back, limiting the aluminum screw 3 between the disc 45 and the limiting assembly. At this time, the rectangular rod 46 is located in the through hole 4, so that the aluminum screw 3 will not rotate during subsequent processing. The aluminum screw 3 is loaded onto the processing rack assembly in accordance with the above method.

[0049] When the third aluminum screw 3 is fed (at which point the first aluminum screw 3 is on the left), the first motor 14 is controlled to run, causing the milling cutter 16 to rotate. At the same time, the operator controls the second pneumatic rod 57 to continuously extend and retract. As the first conductive block 28 rotates to the left and contacts the two contact pieces 29, the solenoid valve on the right side is energized, the air hole is opened, and the extension of the second pneumatic rod 57 causes the piston plate 58 to move upward, forcing the gas in the space above the rectangular box 40 into the cylinder 50. This causes the sliding rod 44 to move the aluminum screw 3 to the left, thereby using the milling cutter 16 to groove the surface of the aluminum screw 3. When the second pneumatic rod 57 is extended to its limit position, a transverse groove is formed on the surface of the aluminum screw 3. Simultaneously, the electrical signal generated by the displacement sensor 60 is transmitted to the controller. The controller controls the first pneumatic rod 48 to first retract and then extend, using the cylinder 50, sliding rod 44, and rectangular rod 46 to rotate the aluminum screw 3 by twenty degrees. The retraction of the second pneumatic rod 57 causes the piston plate 58 to move back, and the gas inside the cylinder 50 enters the rectangular box 40, causing the aluminum screw 3 to move to the right, creating another groove on the aluminum screw 3. After the sliding rod 44 causes the aluminum screw 3 to return to its original position, the displacement sensor 60 again generates an electrical signal, which is transmitted to the controller. The controller then controls the first pneumatic rod 48 to retract and extend once more, causing the aluminum screw 3 to rotate another twenty degrees. Through this process, grooves are uniformly created on the outer surface of the aluminum screw 3, forming a knurled layer.

[0050] After the aluminum screw 3 has been slotted, the first motor 14 stops running and the second motor 18 starts running. At this time, the aluminum screw 3 located at the top rotates to the right to continue the slotting process, and the previously processed aluminum screw 3 rotates to the bottom. During the subsequent slotting process, the second threaded rod 36 is rotated by the first transmission assembly 17 and the crossbar, causing multiple grinding tools 33 to move up and down. Since the multiple grinding tools 33 are directly facing the slotting position, the slotted area of ​​the aluminum screw 3 is ground.

[0051] After the aluminum screw 3 on the left side is knurled again, the second motor 18 runs again. At this time, the second conductive block 43 contacts the arc-shaped conductive sheet 59, and the four corresponding electromagnets 56 will be energized to generate magnetism, attracting the limiting block 54, causing the limiting block 54 to enter the limiting groove. Since the aluminum screw 3 is in a downward tilted state at this time, it will slide onto the worktable 10. The subsequent workers only need to assemble the processed aluminum screw 3 with the other parts of the temperature sensor to complete the production of the temperature sensor.

[0052] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
