[0002] The double-sided griddle is essentially a large grill, mainly used for grilling various foods, such as steak, sausage, eggs, hamburger patties, Indian parathas, pancakes, etc., and is widely used in shopping malls, canteens, hotels and other catering places. The double-sided griddle usually includes a base, a lower grill set, an upper grill set and a lifting rod set. The upper grill set is installed on the lifting rod set, and the lifting rod set is pivotally connected to the base through a hinge. When in use, the lifting rod drives the upper grill set to flip, thereby realizing the opening and closing operation of the upper grill set.

[0003] In order to realize intelligent control and reduce the burden on operators, most commercial double-sided grills on the market currently use cylinder drive and other methods to promote the rotation of the hinge, thereby driving the upper grill group to open or close through the lifting rod group. However, this driving method requires a large driving force and usually can only promote the rotation of the hinge on one side, resulting in unstable opening and closing movements on both sides of the upper grill group. Therefore, there are certain disadvantages. Summary of the invention

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0026] Reference Figures 1 to 4 The present embodiment provides a commercial double-sided grill, comprising a base 1, a lower grill set 2, an upper grill set 3, a lifting rod set 4, a driving mechanism 5 and a height adjustment mechanism 6; the lower grill set 2 is arranged on the base 1, the upper grill set 3 is installed on the lifting rod set 4, and the lifting rod set 4 is pivotally connected to the base through a hinge, so as to be flipped and arranged beside the lower grill set 2 of the base 1. The lifting rod set 4 can be controlled to flip by the driving mechanism 5, so as to drive the upper grill set 3 and the lower grill set 2 to open and close each other; the installation height between the upper grill set 3 and the lifting rod set 4 can be adjusted by the height adjustment mechanism 6, so as to adjust the gap between the upper grill set 3 and the lower grill set 2.

[0027] Reference Figure 1 Preferably, the overall layout of the commercial double-sided grill is as follows: the lower grilling plate group 2 includes a lower grilling plate 21 and a lower heating plate (not shown in the figure), the two lower heating plates are arranged side by side on the base 1, and a lower grilling plate 21 is detachably arranged above the two lower heating plates; the base 1 is provided with an upper grilling plate group 3, a lifting rod group 4, a driving mechanism 5 and a height adjustment mechanism 6 that cooperate with each other on the sides of the two lower heating plates.

[0028] The main innovation of this embodiment lies in the structural design of the driving mechanism 5 and the height adjustment mechanism 6. In order to more clearly explain the innovation, the relevant structure of the driving mechanism 5 is first analyzed in detail below:

[0029] Reference Figures 2 to 4 , the driving mechanism 5 is drivingly connected to the lifting rod group 4, and is used to drive the lifting rod group 4 to rotate around the hinge 42, thereby driving the upper baking pan group 3 to realize the opening and closing operation. Specifically, a connecting frame 41 is provided at one end of the lifting rod group 4, and the connecting frame 41 is pivotally connected to the base 1 through the hinge 42; the driving mechanism 5 is arranged in the base 1, and is drivingly connected to the connecting frame 41, and is used to drive the lifting rod group 4 to rotate around the hinge 42, thereby driving the upper baking pan group 3 to realize the opening and closing operation. In this embodiment, a connecting frame 41 is provided at the end of the lifting rod group 4, and the connecting frame 41 is directly driven by the driving mechanism 5 to flip around the hinge 42. Since there is a certain torque between the force point of the connecting frame 41 and the rotation point of the hinge 42, it can play the effect of a labor-saving lever. Therefore, directly driving the connecting frame 41 can effectively reduce the driving force of the driving mechanism 5, and can ensure that the lifting rod group 4 can smoothly drive the upper baking pan group 3 to flip, thereby solving the shortcomings of the prior art.

[0030] Reference Figures 2 to 4 The connecting frame 41 includes a connecting rod 411 and an arc rod 412 fixed at both ends of the connecting rod 411. The middle part of the connecting rod 411 is connected to the driving mechanism 5, and the arc rod 412 is connected to the hinge 42. The connecting frame 41 is an arc-shaped frame structure as a whole, and can be smoothly rotated around the hinge 42 under the drive of the driving mechanism 5, and the structure is more stable and reliable.

[0031] Reference Figures 2 to 4 The base 1 is provided with a pivot seat 11 beside the lower grill set 2, and a decorative shell 12 covering the outside of the pivot seat 11. The hinge 42 includes a rotating shaft 421 and a connecting piece 422. The rotating shaft 421 is installed in the pivot seat 11, and the two ends of the rotating shaft 421 are provided with connecting pieces 422 connected to the arc rod 412. The connecting piece 422 can play the role of a force arm, so that there is a certain torque between the arc rod 412 and the rotating shaft 421, thereby forming a labor-saving lever, so that the driving mechanism 5 can easily drive the connecting frame 41 to achieve flipping.

[0032] Reference Figure 2 and Figure 3The driving mechanism 5 is an electric push rod 51 or a cylinder, and one end of the driving mechanism 5 is hinged in the base 1 through the mounting seat 52, and the other end is hinged to the middle of the connecting rod 411 of the connecting frame 41. The driving mechanism 5 in this embodiment is preferably an electric push rod 51. In order to realize automatic control, two micro switches 53 for detecting the flipping angle of the lifting rod group 4 are also provided in the base 1 in this embodiment. Both micro switches 53 are controlled and connected to the electric push rod 51. During the flipping process, if the lifting rod group 4 touches the micro switch 53, the electric push rod 51 stops moving, thereby controlling the opening and closing angle of the upper baking tray group 3 within a reasonable range.

[0033] Reference Figure 2 and Figure 3 , a tension spring 54 is provided on both sides of the driving mechanism 5, one end of the tension spring 54 is connected to the base 1, and the other end is connected to the connecting rod 411 of the connecting frame 41. The sum of the tension of the two tension springs 54 is close to the mechanical gravity of the upper baking tray. When the upper baking tray group 3 is opened, the electric push rod 51 is retracted, and the connecting frame 41 is simultaneously subjected to the tension of the electric push rod 51, the tension of the tension spring 54 and the mechanical gravity of the upper baking tray group 3, but the tension of the tension spring 54 can offset the mechanical gravity of the upper baking tray group 3, so the electric push rod 51 can more easily drive the upper baking tray to flip open; when the upper baking tray group 3 is closed, the electric push rod 51 is extended, and the connecting frame 41 is simultaneously subjected to the thrust of the electric push rod 51, the elastic force of the tension spring 54 and the mechanical gravity of the upper baking tray group 3, but the elastic force of the tension spring 54 can offset the mechanical gravity of the upper baking tray group 3, so it can play a buffering effect, ensuring that the upper baking tray group 3 is flipped and closed more smoothly. It can be seen that by arranging the tension spring 54 beside the driving mechanism 5, not only can the driving force of the driving mechanism 5 be reduced, ensuring that the upper baking tray can be flipped open more easily, but also a buffering effect can be achieved, ensuring that the upper baking tray group 3 can be flipped and closed more smoothly.

[0034] Reference Figures 1 to 3 The upper grill set 3 is installed in the middle of the lifting rod set 4, and a handle 44 is provided at the other end of the lifting rod set 4. The handle 44 is vertically provided with a positioning column 441 that abuts against the lower grill set 2. During the process of turning over and closing the upper grill set 3, the positioning column 441 can play a limiting role, which can prevent the upper grill set 3 from turning over too much, and can ensure that the upper grill set 3 is completely turned over to be parallel to the lower grill set 2, thereby avoiding the angle between the upper grill set 3 and the lower grill set 2, which causes uneven force on the food.

[0035] The following is a detailed analysis of the relevant structure of the height adjustment mechanism 6:

[0036] Reference Figures 1 to 4The lifting rod group 4 has a support frame 43 that runs through the upper baking tray group 3. The upper baking tray group 3 can be raised and lowered on the support frame 43 through a height adjustment mechanism 6, so that the gap between the upper baking tray group 3 and the lower baking tray group 2 can be flexibly adjusted to avoid problems such as uneven heating of ingredients and poor cooking effect.

[0037] Reference Figure 2 , Figure 3 and Figure 5 The height adjustment mechanism 6 includes a spring assembly, which includes a plurality of groups of guide rods 61 and springs 62 that cooperate with each other; the support frame 43 is provided with a plurality of sliding holes, one end of the guide rod 61 can be movably arranged in the sliding hole, and the other end of the guide rod 61 is fixedly connected to the upper baking tray group 3; the spring 62 is sleeved on the outside of the guide rod 61 and abuts between the upper baking tray group 3 and the support frame 43. When the thickness of the food between the upper baking tray group 3 and the lower baking tray group 2 changes, the food pressure on the bottom of the upper baking tray group 3 will also change. At this time, the spring 62 will generate reverse elastic potential energy when it is deformed, so as to automatically adjust the height between the upper baking tray group 3 and the support frame 43, thereby ensuring that the bottom of the upper baking tray group 3 always abuts against the surface of the food, so that the baking tray group can adaptively adjust its installation height according to the change of the thickness of the food itself.

[0038] Reference Figure 4 and Figure 5 Specifically, the upper grilling pan assembly 3 includes an upper grilling pan 31, an upper heating pan 32 disposed above the upper grilling pan 31, and a shell 33 covering the upper grilling pan 31 and the upper heating pan 32; the upper heating pan 32 is provided with a recessed portion 321, and the other end of the guide rod 61 passes through the recessed portion 321 and is fixedly connected to the upper grilling pan 31, thereby ensuring that the spring 62 can sensitively adjust the height between the upper grilling pan 31 and the support frame 43 according to the pressure between the upper grilling pan 31 and the food, thereby accurately adjusting the installation height of the upper grilling pan assembly 3.

[0039] Reference Figure 5 A limiting groove is provided in the slide hole, one end of the guide rod 61 passes through the slide hole, and a limiting boss 611 is provided to abut against the limiting groove. The limiting boss 611 can effectively limit the minimum installation height of the upper baking tray assembly 3, and can also play a connecting role, ensuring that the upper baking tray assembly 3 is stably connected to the support frame 43 when it is at the minimum installation height.

[0040] Reference Figure 2 and Figure 5The height adjustment mechanism 6 also includes a screw assembly, which includes a rotating handle 63, an adjusting screw 64 and a fixing nut 65; a through hole is provided in the middle of the support frame 43, and a fixing nut 65 is provided; the adjusting screw 64 is inserted into the fixing nut 65 and the through hole, one end of the adjusting screw 64 extends to the top of the housing 33, and a rotating handle 63 is provided, and the other end of the adjusting screw 64 is rotatably connected to the upper heating plate 32. The rotating handle 63 can drive the adjusting screw 64 to rotate, thereby driving the upper baking tray group 3 to rise and fall compared to the support frame 43, thereby realizing stepless manual adjustment of the installation height of the upper baking tray.

[0041] Reference Figures 2 to 5 More specifically, a mounting hole is provided at the bottom of the upper heating plate 32, and an annular recess 322 is provided at the bottom of the mounting hole. The adjusting screw 64 is rotatably inserted into the mounting hole, and an annular boss 641 is provided to abut against the annular recess 322. With such a design, the upper baking plate set 3 can be hung on the annular boss 641 of the adjusting screw 64, the structure is more optimized, and the installation is simpler, which is conducive to improving production efficiency and reducing production costs.

[0042] Reference Figure 2 and Figure 5 The support frame 43 includes a connecting plate 431 and supporting rods 432 disposed at both ends of the connecting plate 431. A through hole and a fixing nut 65 are disposed in the middle of the connecting plate 431. The screw assembly is disposed in the middle of the connecting plate 431, so that the height of the upper baking tray group 3 can be adjusted smoothly to avoid the angle between the upper baking tray group 3 and the lower baking tray group 2 affecting the cooking effect. As a preferred solution, the supporting rod 432 and the arc rod 412 are an integrated structure with higher structural strength. After cooperating with the connecting rod 411, the connecting plate 431 and the handle 44, a stable and reliable lifting rod group 4 can be formed.

[0043] Reference Figure 4 , strip holes for the support frame 43 to pass through are provided at both ends of the shell 33, and a cover plate 331 for shielding the strip holes is provided outside the shell 33. The strip holes are designed according to the movement path of the upper baking tray group 3, and can play a guiding and limiting role. The cover plate 331 can effectively shield the structure in the strip holes, ensuring the sealing and overall aesthetics of the upper baking tray group 3.

[0044] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
