[0042] like Figures 1 to 5 As shown, the present application provides a grilling machine with reliable structure, including an upper grilling pan assembly, the upper grilling pan assembly including a cover body and a heating tube 10 installed in the cover body, the cover body is provided with an installation cavity 11 and an accommodating cavity 12 protruding relative to the installation cavity 11, the accommodating cavity 12 is communicated with the installation cavity 11, the heating tube 10 includes a heating section 101 and a connecting section 102 connected to the heating section 101, the heating section 101 is arranged in the installation cavity 11, one end of the heating section 101 is bent upward and extends into the accommodating cavity 12, so that the connecting section 102 is arranged in the accommodating cavity 12, so that the connecting section 102 and the heating section 101 are arranged on different planes.

[0043] The grilling machine with reliable structure of the present application optimizes the shape of the heating tube 10 and sets the installation cavity 11 and the accommodating cavity 12 with different height distributions, so that the connecting section 102 and the heating section 101 can be arranged separately and set on different planes, which can prevent the high temperature of the heating section 101 from being transferred to the connecting section 102. On the one hand, it can ensure that the temperature near the connecting section 102 is appropriate and ensure that the connecting section 102 has a good electrical connection effect with other circuits. On the other hand, it can prevent the glue near the connecting section 102 from melting to expose the heating element inside the heating tube 10, thereby reducing safety risks, avoiding heat loss and ensuring the heating efficiency of the heating tube 10.

[0044] The heat of the heating section 101 is mainly concentrated at the position of the installation cavity 11, so that the heat mainly acts on the food. When very little heat is transferred to the accommodating cavity 12, it can also be dissipated through the space of the accommodating cavity 12, so that very little heat is transferred to the end of the connecting section 102, thereby protecting the connecting section 102 from high temperature, improving the reliability and safety of the use of the heating tube 10, and helping to extend its service life.

[0045] Specifically, Figure 2 or Figure 4 As shown, the heating section 101 of the heat pipe 10 includes a plurality of concentrically arranged annular structures. The heating section 101 constitutes the main heat source of the heat pipe 10. By optimizing the distribution density of the annular structure, it is beneficial to improve the heating efficiency and the uniform distribution of heat, thereby improving the uniformity of heating the food. The shape of the mounting cavity 11 is adapted to the shape of the heating section 101. In this embodiment, the mounting cavity 11 is circular. When the heating section 101 is arranged, the heating section 101 can be directly installed in contact with the mounting cavity 11, or the heating section 101 can be fixed to the mounting cavity 11 by a mounting bracket 16. Furthermore, a notch is provided in the mounting cavity 11 to form a receiving cavity 12, and the receiving cavity 12 protrudes upward relative to the mounting cavity 11, that is, the top of the receiving cavity 12 is higher than the top of the mounting cavity 11. One end of the heating section 101 is connected to the horizontally extending connecting section 102 through an upward bending section 103, so the connecting section 102 is at a high position and the heating section 101 is at a low position, and the connecting section 102 can be accommodated in the accommodating cavity 12, so that the connecting section 102 and the heating section 101 are distributed on different planes. Among them, the shape of the accommodating cavity 12 is adapted to the shape of the connecting section 102. In this embodiment, the accommodating cavity 12 is rectangular and can accommodate the horizontally extending connecting section 102. A sheet-shaped connecting terminal 104 is provided at the end of the connecting section 102, and a sealing glue is usually provided at the connection position between the connecting terminal 104 and the cylindrical heating tube 10. In this application, the connecting section 102 is set away from the heating section 101 and arranged on different planes, which can effectively reduce the temperature near the connecting terminal 104, and can avoid the melting of the glue to expose the heating element inside the heating tube 10, which not only ensures the safety of the use of the heating tube 10, but also reduces the heat loss, thereby ensuring the heating efficiency.

[0046] The formation of the accommodating cavity 12 can be set according to actual needs. For example, in one embodiment, Figure 2 As shown, the accommodating cavity 12 is integrally formed with the cover body, that is, a position in the installation cavity 11 of the cover body is provided with the accommodating cavity 12. Figure 2 In the perspective of FIG. 1 , the accommodating cavity 12 is recessed relative to the mounting cavity 11, and the two have different height distributions. In this way, when the cover body is processed, the mounting cavity 11 and the accommodating cavity 12 can be formed at the same time, which has a simple structure and is easy to process. In another embodiment, as shown in FIG. Figure 3 As shown, the accommodating cavity 12 is formed by a separate cover shell 13. In this embodiment, the cover body is provided with a through installation opening, and the cover shell 13 can be installed at the installation opening. The cover shell 13 is a structure with a closed top and an open bottom. The cover shell 13 is connected to the installation cavity 11 through the bottom opening.

[0047] As a preferred embodiment of the present application, the connecting section 102 is provided with a connecting terminal 104 , and a through hole 121 is provided on a side wall of the accommodating cavity 12 away from the center of the cover body, and the connecting terminal 104 extends out of the accommodating cavity 12 through the through hole 121 .

[0048] like Figure 2 As shown, a sheet-shaped connection terminal 104 is provided at the end of the connection section 102. To facilitate the connection terminal 104 to pass through, the through hole 121 is in a long strip shape, and the number of through holes 121 is set according to actual needs. The connection terminal 104 extends out of the accommodating cavity 12 to facilitate connection with an external circuit, so that the electrical connection position is protected from the high temperature of the heating section 101, and the reliability of the electrical connection can be ensured, and the heating tube 10 can be powered on and work normally.

[0049] Furthermore, the cover body is provided with an end cover 14 , and the end cover 14 is fixed to the outer wall of the through hole 121 to cover the connecting terminal 104 therein.

[0050] like Figure 2 or Figure 5 As shown, by providing the end cap 14, the connection terminal 104 and the electrical connection components can be protected from dust and water, and the electrical connection position can be prevented from being exposed to moisture and damage in the environment, and water can be prevented from entering the electrical connection position to cause short circuits, leakage and other accidents, thereby improving the safety of use. The end cap 14 and the cover body can be fixed by screws, for example, and one side of the end cap 14 is opened for the connection terminal 104 to extend into the end cap 14, and the other side of the end cap 14 is closed to enhance the waterproof effect. In order to facilitate other circuits to extend into the end cap 14 and connect with the connection terminal 104, a wire hole is provided on the end cap 14.

[0051] To optimize the limiting of the connecting section 102 , further, a positioning piece 15 is provided in the accommodating cavity 12 . The positioning piece 15 is passed through and fixed to the outer wall of the connecting section 102 , and the positioning piece 15 is stopped and fixed to the inner wall of the outer edge of the through hole 121 .

[0052] like Figure 2As shown, by providing the positioning piece 15, since the positioning piece 15 is limited by the accommodating cavity 12, and the positioning piece 15 is fixed to the connecting section 102, the connecting section 102 can be prevented from shifting, so that the connecting terminal 104 can be stably maintained outside the accommodating cavity 12, which is beneficial to the reliability of the electrical connection between the connecting terminal 104 and the external circuit. During specific installation, the positioning piece 15 can be firstly inserted into the connecting section 102, and the positioning piece 15 and the cylindrical tube of the connecting section 102 are, for example, riveted, and then when the connecting section 102 is placed in the accommodating cavity 12, the connecting terminal 104 is passed through the through hole 121, and then the positioning piece 15 is against the inner wall at the through hole 121, and the positioning piece 15 and the inner wall at the through hole 121 can be fixed by screws, for example, to achieve limiting.

[0053] As a preferred embodiment of the present application, the heating section 101 and the connecting section 102 are connected via a bending section 103 , and the height of the accommodating cavity 12 is not less than the height of the bending section 103 .

[0054] like Figure 2 , Figure 4 or Figure 5 As shown, the bending section 103 extends vertically, and the connecting section 102 extends horizontally outward. The bending section 103 can be arranged along the height direction of the accommodating cavity 12 so that the connecting section 102 can be accommodated in the accommodating cavity 12. When the height of the accommodating cavity 12 is equal to the height of the bending section 103, the connecting section 102 can be arranged in contact with the top wall of the accommodating cavity 12. When the height of the accommodating cavity 12 is greater than the height of the bending section 103, the connecting section 102 does not fit the top wall of the accommodating cavity 12. For example, the connecting section 102 and the accommodating cavity 12 can be fixed by a structure such as a bracket. At this time, the accommodating cavity 12 has a larger volume. Even if part of the heat of the heating section 101 is transferred to the accommodating cavity 12, the heat can be quickly dissipated through the accommodating cavity 12, thereby reducing the impact of high temperature on the connecting section 102.

[0055] As a preferred embodiment of the present application, a mounting bracket 16 is provided in the mounting cavity 11 , and the heating section 101 is fixed to the mounting bracket 16 to be isolated from the mounting cavity 11 by the mounting bracket 16 .

[0056] like Figure 2 As shown, by providing the mounting bracket 16, the heating section 101 does not directly contact the inner surface of the cover body but is isolated from the mounting cavity 11 by the mounting bracket 16, which can prevent the high temperature of the cover body from easily scalding the user, making the product safer to use. The mounting bracket 16 is, for example, a vertical plate. In order to achieve multi-ring ring structure support, the mounting bracket 16 is, for example, a vertical plate with a triangular distribution, which can evenly support the heating section 101. The heating section 101 can be fixed to the mounting bracket 16 by a wire clip 161.

[0057] In order to further improve the heating efficiency and the energy utilization rate, the inner top wall of the installation cavity 11 may be provided with a reflective layer structure, for example, to reflect the heat of the heating section 101 so that the heat of the heating section 101 can fully act on the food.

[0058] As a preferred embodiment of the present application, the cover body includes an outer cover 17 and an inner cover 18 , the accommodating cavity 12 is arranged in the inner cover 18 , and the outer cover 17 is provided with an avoidance cavity 171 corresponding to the accommodating cavity 12 .

[0059] By adopting a double-layer cover structure, the heating tube 10 is arranged in the inner cover 18. On the one hand, less heat from the heating tube 10 is transferred to the outer cover 17, which can avoid the outer cover 17 from having a high temperature and the user will not be burned when touching the outer cover 17. On the other hand, the outer cover 17 has a heat-insulating effect, which can reduce heat loss and help improve heating efficiency.

[0060] like Figure 2 As shown, the inner cover 18 and the outer cover 17 are arranged in a similar manner, the outer cover 17 covers the outer side of the inner cover 18, and can receive the accommodating cavity 12 through the avoidance cavity 171. The heating pipe 10 is fixed to the inner surface of the inner cover 18, and a reflective layer can be provided on the inner surface of the inner cover 18 to improve the heat utilization rate.

[0061] Furthermore, a handle 19 is provided on the outer top wall of the avoidance cavity 171 , and the handle 19 and the outer cover 17 are detachably mounted.

[0062] By providing the handle 19, since the handle 19 is provided on the outer cover 17, the temperature of the outer cover 17 is low and the user will not be burned when holding the handle 19, and the use is safe, and the handle 19 is easy to disassemble. When the grilling machine needs to be stored, the handle 19 can be disassembled and stored separately, which is conducive to reducing the volume of the grilling machine and facilitating storage. The handle 19 and the outer cover 17 can be plugged and installed, for example, to facilitate the disassembly and assembly of the handle 19. Figure 1 As shown, when the avoidance cavity 171 is arranged along the center line of the grill, the handle 19 can be arranged in the center. When the user operates the handle 19 to lift the cover, the force on the cover body can be evenly applied, which facilitates stable opening of the cover.

[0063] As a preferred embodiment of the present application, the outer top wall of the cover body is provided with an upwardly protruding circuit board installation box 20, and a circuit board 21 is arranged in the circuit board installation box 20. The accommodating cavity 12 extends radially along the cover body, and the circuit board installation box 20 is arranged on one side of the accommodating cavity 12 and is arranged alternately with the accommodating cavity 12.

[0064] like Figure 1 and Figure 2As shown, in the scheme where the cover body includes an outer cover 17 and an inner cover 18, when the accommodating cavity 12 and the avoidance cavity 171 are arranged on the center line of the grilling machine, if the outer top wall of the avoidance cavity 171 is provided with a handle 19, the handle 19 can be arranged in the center, so that when the user flips the cover, the cover body is evenly stressed, and the cover opening can be stable; and the horizontal arrangement of the circuit board installation box 20 can improve the space utilization rate, so that there is sufficient space to arrange the circuit board 21, and the circuit board installation box 20 and the avoidance cavity 171 are arranged in a T-shape, which is beneficial to the appearance of the grilling machine. The circuit board installation box 20 is formed by a rib that protrudes upward, and a cover plate 22 is provided on the top of the rib to close and hide the circuit board 21, providing dustproof and waterproof protection.
