[0030] The present invention will be further described below with reference to specific embodiments:
[0031] An oven heater fixing mechanism includes an oven liner 1, a heater 2, and a support frame 3; as shown Figure 1 , 2 As shown, the oven liner 1 in this patent is used to be installed inside the casing of a high-temperature steak oven. The oven liner 1 is used to place steaks for baking. In this patent, the top plate 11 of the oven liner 1 is provided with a first mounting port 11. The heater 2 includes a fixed base 21 fixed in the first mounting port 11 and a heat conduction part 22 connected to the fixed base 21. The heat conduction part 22 is provided with a heating source. The fixed base 21 is used to connect to the power supply in the oven. The heat conduction part 22 is a trapezoidal ceramic shell with a square bottom surface. The heating source is a heating tube disposed in the heat conduction part 22. The heating tube is connected to the fixed base 21 by a wire and connected to the power supply in the oven through the fixed base 21. The power supply enables the heating source to work and transfers heat to the oven liner 1 through the heat conduction part 22 for cooking.
[0032] The support frame 3 is fixed in the oven liner 1. The support frame 3 has a support portion 31 that supports the heat conduction part 22. The support portion 31 has a heat conduction port 32 that allows the heat conduction part 22 to face the oven liner 1. Figure 2-4As shown, the support frame 3 in this patent is made of stainless steel and is a frame structure adapted to the bottom shape of the heat conduction part 22. Since the heat conduction part 22 in this patent has a square bottom surface, the support frame 3 is a square frame whose size is adapted to the bottom surface of the heat conduction part 22. The frame has a heat conduction port 32 formed in it, which is slightly smaller than the bottom surface area of the heat conduction part 22. During installation, the support frame 3 is fixed in the oven liner 1, and the fixing base 21 of the heater 2 is installed in the first mounting port 11, so that the heat conduction part 22 is located in the support frame 3 of the oven liner 1. At this time, the edge of the bottom surface of the heat conduction part 22 abuts against the support part 31, and most of the bottom surface of the heat conduction part 22 is exposed to the outside through the heat conduction port 32 for heat conduction.
[0033] Furthermore, the support portion 31 is also provided with a vertically placed annular edge 311, which is used to limit the heat conduction portion 22 on its outer wall. At this time, the cross-section of the support portion 31 is "L" shaped, which can cover the bottom edge and outer wall of the heat conduction portion 22, thereby limiting the horizontal movement of the heat conduction portion 22 and preventing the heater 2 from swaying left and right in the support frame 3, thus increasing stability.
[0034] like Figure 3-6 The supporting portion 31 shown has connecting arms 33 at both ends, which are connected to the top plate 11 of the oven liner 1. Correspondingly, a fixing bracket 4 is also included, which is installed outside the oven liner 1. An assembly 5 connecting the fixing base 21 is provided on the fixing bracket 4. Fasteners connecting the fixing bracket 4, the connecting arms 33, and the oven liner 1 are provided. Figure 3-5As shown, the mounting bracket 4 is rectangular, with connecting feet 41 at both ends. Each connecting foot 41 has a fastening hole, through which screws secure the mounting bracket 4 to the oven's outer shell. A second mounting opening 42 is located in the middle of the mounting bracket 4. The mounting base 21 of the heater 2 is located in both the first mounting opening 11 and the second mounting opening 42. Fixing is achieved by providing a wave-shaped spring piece 51 and an insert piece 52 on the mounting base 21. Specifically, the mounting base 21 has a positioning groove 211, the wave-shaped spring piece 51 is located within the positioning groove 211, and the insert piece 52 is inserted into the positioning groove 211, pressing one side of the wave-shaped spring piece 51 so that the outer end of the wave-shaped spring piece 51 presses against the mounting bracket 4. Furthermore, the fixing bracket 4 is attached to the outer wall of the top plate 11 of the oven liner 1, while the connecting arm 33 on the support bracket 3 abuts against the outer wall of the top plate 11 of the oven liner 1 and is opposite to the fixing bracket 4. Threaded holes are provided at the positions where the fixing bracket 4 and the connecting arm 33 are opposite. By installing threaded fasteners on the fixing bracket and passing them through the oven liner 1 to connect with the connecting arm 33, the connection of the three is realized, thereby increasing the stability of the support bracket 3 and the fixing bracket 4 after installation, so that the support bracket 3 can provide more stable support.
[0035] In summary, this patent uses the support frame 3 to support the heat conduction part 22 of the heater 2, preventing the heater 2 from shaking due to bumps during oven transportation, reducing the loosening or damage of the assembly components 5 on the heater 2 caused by the shaking of the heater 2, and effectively reducing the impact of transportation bumps on the oven.
[0036] In other embodiments, the connecting arm 33 of the support frame 3 can be placed horizontally on both sides of the support portion 31. In this case, the connecting arm 33 is fixed on the left and right sides of the oven liner 1. Compared with the previous embodiment, after the connecting arm 33 is connected to the top plate 11 of the oven liner 1, the connecting arm 33 occupies less volume, which can make the space in the oven liner 1 available for cooking larger.
