[0053] Combination Figures 1 to 18 As shown, according to a specific embodiment of the present application, a baking tray assembly is provided.

[0054] Specifically, the grill pan assembly includes an upper grill pan assembly 10, a lower grill pan assembly 20, an operating member 30 and a transmission rod assembly 40; the lower grill pan assembly 20 is movably connected to the upper grill pan assembly 10, and a cooking space is formed between the upper grill pan assembly 10 and the lower grill pan assembly 20; the operating member 30 is movably connected to the upper grill pan assembly 10; the transmission rod assembly 40 includes a transmission rod 41 and a support portion 42, the length direction of the transmission rod 41 extends along the radial direction of the upper grill pan assembly 10, the transmission rod 41 is movably connected to the upper grill pan assembly 10, and at least one support portion 42 is respectively provided at both ends of the transmission rod 41, and the support portion 42 has a preset rotation angle to increase the upper grill pan assembly The support position of the cooking space volume formed between the plate assembly 10 and the lower baking plate assembly 20, and the support portion 42 has a storage position that allows the upper baking plate assembly 10 to be arranged close to one side of the lower baking plate assembly 20 to reduce the cooking space volume formed between the upper baking plate assembly 10 and the lower baking plate assembly 20. The transmission rod 41 is arranged in coordination with the operating member 30. The operating member 30 can drive the transmission rod 41 to drive the support portion 42 to rotate to the support position and the storage position; wherein, when the support portion 42 is located at the supporting position, at least a portion of the support portion 42 is in contact with the lower baking plate assembly 20, and when the support portion 42 is located at the storage position, the support portion 42 is located on one side of the lower baking plate assembly 20.

[0055] By applying the technical solution of the present embodiment, the lower baking tray assembly 20 is movably connected to the upper baking tray assembly 10, the operating member 30 is movably connected to the upper baking tray assembly 10, the transmission rod 41 is movably connected to the upper baking tray assembly 10, the operating member 30 cooperates with the transmission rod 41, and by operating the operating member 30, the transmission rod 41 transmits the power on the operating member 30 to the support portion 42. When the support portion 42 rotates to the supporting position, at least part of the support portion 42 abuts against the lower baking tray assembly 20, and the cooking space between the upper baking tray assembly 10 and the lower baking tray assembly 20 becomes larger. When the support portion 42 rotates to the storage position, the cooking space between the upper baking tray assembly 10 and the lower baking tray assembly 20 becomes smaller, so that the space adjustment of the upper baking tray assembly 10 and the lower baking tray assembly 20 of the baking tray assembly can be realized. The baking tray assembly using the present application has a simple structure and high reliability, which improves the user experience. In this embodiment, when the support portion 42 is located at the storage position, a single support portion 42 is located on one side of the lower baking tray assembly 20, that is, if there are multiple support portions 42, the multiple support portions 42 can be located on one side of the lower baking tray assembly 20 respectively.

[0056] Specifically, Fig.15As shown, the upper baking tray assembly 10 includes an outer shell 11, an inner shell 12 and an upper baking tray 14; the inner shell 12 is connected to the outer shell 11, and the inner shell 12 is connected to the outer shell 11 on the side facing the lower baking tray assembly 20, and the inner shell 12 and the outer shell 11 are surrounded by a receiving space 13, a transmission rod 41 is arranged in the receiving space 13, a part of the operating member 30 extends through the outer shell 11 into the receiving space 13 and is arranged in cooperation with the transmission rod 41, and another part of the operating member 30 is located on the outer side of the outer shell 11 to form an operating end, a part of the supporting portion 42 is located in the receiving space 13, and another part of the supporting portion 42 extends to the outside of the receiving space 13; the upper baking tray 14 is connected to the surface of the inner shell 12 on the side facing the lower baking tray assembly 20, and the two supporting portions 42 are both located on the outer side of the upper baking tray 14. In this way, the transmission rod 41 and part of the operating member 30 are arranged in the accommodating space 13. The accommodating space is formed by the outer shell 11 and the inner shell 12, and has good sealing and stability, thereby improving the service life of the transmission rod 41, the support part 42 and the operating member 30.

[0057] It should be noted that part of the operating parts 30 are located in the accommodating space 13, and the other part of the operating parts 30 are located outside the accommodating space 13. The operating parts 30 are inserted into the outer shell 11. When the cooking space needs to be adjusted, it is only necessary to operate the operating end of the operating part 30 located outside the accommodating space 13 to drive the part of the operating part 30 and the transmission rod 41 located in the accommodating space 13 to move. The transmission rod 41 further drives the support part 42 to support the upper baking tray assembly 10 to expand the cooking space and relieve the force on the upper baking tray assembly 10 to reduce the cooking space.

[0058] Furthermore, if Figure 2 , Figure 3 , Figure 6 As shown, a turbine 411 is provided on the transmission rod 41, and a worm 31 matched with the worm 411 is provided on the operating member 30. The operating member 30 is rotated so that the worm 31 drives the worm 411 to drive the transmission rod 41 to rotate by a preset angle. Such a structure is simple, and assembly and operation are convenient. The worm 31 is provided with a thread, and the worm 411 part is gear-shaped. The thread head is meshed with the tooth part of the worm 411. The worm 31 is rotated around the axis by rotating the operating end of the operating member 30. The thread head of the worm 31 drives the worm 411 to rotate along the circumferential direction of the transmission rod 41, and then drives the transmission rod 41 to rotate, so as to adjust the support part 42 and achieve the purpose of adjusting the size of the cooking space.

[0059] In one embodiment of the present application, Figures 2 to 6 and Figure 8 As shown, the axis of the worm 31 is arranged perpendicularly to the axis of the transmission rod 41. This facilitates the regular design of the thread shape on the worm 31 and the shape of the turbine 411, simplifies the structure, and saves material and assembly costs.

[0060] The worm shaft 31 is located in the accommodation space 13. Figure 2 and Fig.13 As shown, the worm 31 is located at the lower side of the operating end of the operating member 30, which is the part of the operating member 30 located in the accommodating space 13. The airtightness of the accommodating space 13 can prevent the lubricating oil on the worm 31 and the turbine 411 from evaporating or being affected by other components, thereby ensuring the good function of the operating member 30 and improving the service life of the equipment.

[0061] Furthermore, if Figure 3 and Fig.14 As shown, the upper grill assembly 10 further includes a limiting structure 15, which is disposed in the accommodating space 13 and is connected to at least one of the outer shell 11 and the inner shell 12. The limiting structure 15 has a limiting space 151, and the turbine 411 is disposed in the limiting space 151. The transmission rod 41 is disposed through the limiting space 151, and the turbine 411 is movably disposed relative to the limiting structure 15. This arrangement can relatively fix the position between the turbine 411 and the transmission rod 41 in the limiting space 151, and the transmission rod 41 passes through the geometric center of the upper grill assembly 10. The limiting space 151 fixes the turbine 411 to the geometric center of the upper grill assembly 10, so that the turbine 411 can evenly transmit the rotational torque to the transmission rod 41, thereby improving the adjustment accuracy of the support portion 42 and the cooking space.

[0062] It should be noted that the limiting structure 15 is detachably connected to the outer shell 11 or the inner shell 12, or is a limiting column integrally formed with one of them. There are four limiting columns, and the four limiting columns are arranged to form a limiting space 151. The turbine 411 is sleeved on the transmission rod 41, and the transmission rod 41 passes through the turbine 411 and the limiting space 151, which can prevent the turbine 411 from sliding along the axial direction of the transmission rod 41.

[0063] Specifically, Figure 8 and Fig.10 As shown, the turbine 411 includes a turbine body 4110, a transmission rod 41 connected to the turbine body 4110, a portion of the outer circumference of the turbine body 4110 is an arc surface 4111, and another portion of the outer circumference of the turbine body 4110 is provided with a tooth portion 4112. In this way, the turbine body 4110 is sleeved on the transmission rod 41 to achieve a rotational connection between the turbine body 4110 and the transmission rod 41, and the portion of the outer circumference of the turbine body 4110 provided with the tooth portion 4112 is meshed with the thread of the worm rod 31 to achieve that the thread of the worm rod 31 drives the tooth portion 4112 to rotate, and the arrangement of the non-contact outer circumference of the turbine body 4110 and the worm rod 31 as the arc surface 4111 can reduce the number of the tooth portions 4112, thereby reducing the processing workload and assembly process of the turbine body 4110, and can also save materials.

[0064] Specifically, the number of teeth 4112 is N, where 1≤N≤4. Since the adjustment of the cooking space size by the grilling pan device and the grilling machine is a precise adjustment, a limited number of teeth 4112 can be set to meet the adjustment of the cooking space, and the more teeth 4112 there are, the greater the rotation angle of the transmission rod 41, and the greater the rotation angle of the support part 42, and the larger the adjustable size of the cooking space. In one embodiment of the present application, Figure 7 and Fig. 9 As shown, the number N of the teeth 4112 is 4, which can correspondingly adjust the support portion 42 to rotate to the supporting position and the storage position.

[0065] Specifically, Fig.10 As shown, the lead angle of the tooth portion 4112 is β, where 0≤β≤90°. It should be noted that the lead angle β is the angle between two adjacent tooth portions 4112 along the axial direction of the turbine body 4110. The setting of the lead angle β can be set according to the specific size and number of the thread head of the worm 31 and the tooth portion 4112. The number N of the tooth portions 4112 and the lead angle β satisfy the relationship: β*N≤360°. Therefore, when β satisfies 0≤β≤90° and the number N of the tooth portions 4112 satisfies 1≤N≤4, the meshing of the tooth portion 4112 and the thread head of the worm 31 is more stable, which can improve the adjustment accuracy of the cooking space.

[0066] Furthermore, the number of thread starts of the worm 31 is n, where 1≤n≤4. Figure 7 and Figure 8 As shown, the number of thread heads n is equal to the number N of teeth 4112, and they are arranged one-to-one. This ensures that the support portion 42 can be self-locked when rotated to any angle to keep the cooking space stable. It can also prevent the excess number of thread heads n or the number N of teeth 4112 from affecting the rotation of the turbine 411 and affecting the adjustment effect. At the same time, it can simplify the structure and facilitate the assembly process.

[0067] Furthermore, if Figure 2 , Figure 4 and Figure 6 As shown, at least one support portion 42 includes a support body 421, a first end of the support body 421 is connected to the transmission rod 41, a second end of the support body 421 is extended away from one side of the transmission rod 41, and the second end of the support body 421 has a plurality of support points in contact with the lower grill assembly 20, and the operation member 30 can drive the transmission rod 41 to drive the support body 421 to stay at any support point. This arrangement can be operated according to the requirements of the cooking space for different ingredients, and the operation member 30 can be operated to drive the transmission rod 41 to drive the support body 421 to stay at any support point, so that the support portion 42 can stay at any position between the storage position and the support position.

[0068] Specifically, when the support body 421 is located at each support point, the heights of each cooking space formed between the upper grill plate assembly 10 and the lower grill plate assembly 20 are different. The support body 421 is located at each different support point by the transmission rod 41 rotating to drive the support body 421 to rotate. Therefore, any asymmetric arc structure can be set within the rotation angle of the support body 421 to achieve different settings of the height of the cooking space, that is, the transmission rod 41 is located at a non-center of the support body 421. It should be noted that the support body 421 can be set to a regular arc shape or an irregular arc shape, such as an ellipse. When the support body 421 is a regular arc shape, the height of the cooking space can be uniformly changed with the adjustment of the operating member 30. When the support body 421 is an irregular arc shape, the height of the cooking space can also be set non-uniformly.

[0069] In one embodiment of the present application, Figures 11 to 13 As shown, the support body 421 includes a first component segment 4210 and a second component segment 4211, wherein the first end of the first component segment 4210 is connected to the transmission rod 41; the first end of the second component segment 4211 is connected to the second end of the first component segment 4210 and is arranged at an angle, and the second end of the second component segment 4211 is gradually extended away from the first component segment 4210, wherein a plurality of support points are formed on the second component segment 4211. In this way, the connection between the first end of the first component segment 4210 and the transmission rod 41 is used as the center of rotation, since the distances from each support point on the second component segment 4211 to the center of rotation are different. When the support portion 42 is in the storage position, as shown in FIG. Fig.12 As shown, the second end of the first group segment 4210 is in contact with the lower grill assembly 20, and the cooking space size is minimum at this time. When the support portion 42 is in the supporting position, as shown in FIG. Fig.15 As shown, the second end of the second component segment 4211 is abutted against the lower baking tray assembly 20. At this time, the cooking space size is maximized. Multiple support points are formed on the second component segment 4211 so that when the transmission rod 41 rotates and self-locks, each support point can be abutted against the lower baking tray assembly 20, thereby achieving different heights of the cooking spaces formed between the upper baking tray assembly 10 and the lower baking tray assembly 20.

[0070] Preferably, the second segment 4211 is an arc-shaped structure, which can facilitate the rotation of the operating member 30 and the supporting body 421, and the arc-shaped structure can reduce the friction between the second segment 4211 and the lower grill assembly 20 when rotating, thereby reducing the friction loss between the components.

[0071] Furthermore, if Fig.11 and Fig.12As shown, the distance from the support point at the end position close to the second end of the second assembly segment 4211 to the axis of the transmission rod 41 is L1, and the distance from the support point at the end position close to the first end of the second assembly segment 4211 to the axis of the transmission rod 41 is L2. Among them, L1 = L2. This setting can make the adjustment change of the cooking space uniform, and L1 and L2 can also be unequal, and the difference between L1 and L2 is consistent with the suspension height of the cooking space formed by the baking tray assembly.

[0072] Furthermore, the outer edge profile of the second group segment 4211 is an Archimedean spiral. This arrangement makes the thread an equidistant spiral, uniform and having good structural stability and torsion resistance, and can produce a flat and stable motion trajectory.

[0073] Furthermore, the thickness of the support body 421 is L3, wherein 0.1 mm ≤ L3 ≤ 50 mm. In this way, the thickness of the support body 421 can be adjusted according to the size of the support portion 42, so as to facilitate locking of each supporting point on the second group segment 4211.

[0074] Furthermore, if Figure 17 to Figure 18 As shown, the upper baking tray assembly 10 further includes at least one positioning assembly 16, which is disposed in the accommodation space 13, and is connected to at least one of the outer shell 11 and the inner shell 12. The positioning assembly 16 is provided with a positioning hole, and the transmission rod 41 can be movably inserted into the positioning hole. This arrangement can stably set the transmission rod 41 in the accommodation space 13, and the transmission rod 41 can be movably inserted into the positioning hole to ensure that the transmission rod 41 can only move in the accommodation space 13 in a rotating manner, and only provide a rotational torque. At the same time, the positioning assembly 16 can also ensure that the transmission rod 41 is not interfered with by other components, which affects the transmission effect.

[0075] Specifically, Figure 2 and Figure 3 As shown, the positioning assembly 16 includes a positioning column 161 and a pressing plate 162. The positioning column 161 is connected to at least one of the outer shell 11 and the inner shell 12; the pressing plate 162 is connected to the positioning column 161, and a positioning hole is formed between the pressing plate 162 and the positioning column 161. The positioning column 161 is integrally connected to one of the outer shell 11 and the inner shell 12. According to the principle of lever, the positioning column 161 is arranged on a side close to the support portion 42, and only a small pressure is required to maintain the stability of the transmission rod 41, that is, the positioning assembly 16 of the same strength can provide stronger stability. A positioning hole is formed between the pressing plate 162 and the positioning column 161, and the transmission rod 41 passes through the positioning hole to be connected to the support portion 42, and the pressing plate 162 and the positioning column 161 are connected by screws to ensure the stability of the positioning hole.

[0076] In one embodiment of the present application, Fig.14 , Fig.17 , Fig.18 As shown, the positioning assembly 16 includes four positioning columns 161 and two pressing plates 162. The four positioning columns 161 are divided into two groups. Each group of positioning columns 161 is parallel to the worm 31 and is respectively arranged on both sides of the inner shell 12 close to the support portion 42. The two positioning columns 161 of each group of positioning columns 161 are arranged at intervals, and the interval distance between the two positioning columns 161 is the diameter of the transmission rod 41; the two pressing plates 162 are respectively connected to each group of positioning columns 161 by screws, and the pressing plate 162 and the two positioning columns 161 form a positioning hole for the transmission rod 41 to pass through.

[0077] Furthermore, if Fig.15 and Fig.16 As shown, the lower baking tray assembly 20 includes a bottom shell 21 and a lower baking tray 23, the bottom shell 21 has an installation cavity 22; at least a portion of the lower baking tray 23 is arranged in the installation cavity 22, and two support portions 42 are located outside the edge of the lower baking tray 23, and a support platform 211 is formed at a position of the bottom shell 21 opposite to the support portion 42; wherein, by rotating the operating member 30 at a preset angle, the transmission rod 41 can drive the support portion 42 to drive the upper baking tray assembly 10 to move relative to the lower baking tray 23, so as to change the height of the cooking space formed between the upper baking tray 14 and the lower baking tray 23. In this way, the components of the lower baking tray assembly 20 are arranged in the installation cavity 22, thereby ensuring the stability of the lower baking tray assembly 20, that is, the components in the lower baking tray assembly 20 are all stable components, and there is no need to set transmission components and structures. When the size of the cooking space needs to be adjusted, the operating member 30 is rotated by a preset angle only to issue movement instructions to the worm rod 31, the turbine body 4110, the transmission rod 41 and the support part 42 in the accommodating space 13 of the upper baking tray assembly 10, so that relative movement is generated between the upper baking tray assembly 10 and the lower baking tray assembly 20, which can simplify the structure and improve the stability and reliability of the baking tray assembly.

[0078] According to another specific embodiment of the present application, a grilling machine is further provided, comprising a grilling pan assembly, which is the grilling pan assembly in the above embodiment.

[0079] The present application also provides a preferred embodiment of a grilling pan assembly and a grilling machine having the same, which aims to solve the problem in the prior art that the size of the cooking space formed by the grilling pan assembly of the grilling machine cannot be adjusted at any time.

[0080] Specifically, the baking tray assembly includes an upper baking tray assembly 10 and a lower baking tray assembly 20, the upper baking tray assembly 10 includes an operating member 30, a worm rod 31, a turbine 411, a transmission rod 41, a positioning assembly 16, a support portion 42, a shell, and a support receiving groove and an upper baking tray 14 are provided on the shell, wherein the support receiving groove is used to receive the support portion, such as Fig.16 As shown, the support receiving groove is formed between the outer shell 11 and the inner shell 12). The lower baking tray assembly 20 includes a lower baking tray 23, a shell and a support platform 211.

[0081] The turbine 411 is fixedly installed in the limited space 151 to prevent the turbine 411 from moving axially. The turbine body 4110 is provided with a tooth portion 4112. The number of the tooth portions 4112 corresponds to the number of thread heads on the worm 31. The lead angle of the tooth portion 4112 is β, where 0≤β≤90°. The transmission rod 41 is fixedly connected to the outer shell 11 or the inner shell 12 through the positioning assembly 16. The outer shell 11 is symmetrically provided with support accommodating grooves. The thickness of the support body 421 is L3, where 0.1mm≤L3≤50mm; the support body 421 includes a first component segment 4210 and a second component segment 4211. The second component segment 4211 is an arc structure, and the outer edge profile of the second component segment 4211 is an Archimedean spiral.

[0082] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0083] 1) The upper baking tray assembly 10 is driven to move upward or downward by operating the operating member 30 to adjust the size of the cooking space formed between the upper baking tray assembly 10 and the lower baking tray assembly 20 to suit different food thicknesses.

[0084] 2) The operating member 30 drives the worm gear 31 to rotate, and the worm gear 31 drives the turbine 411 to rotate, thereby driving the transmission rod 41 and the support body 421 to rotate, so as to switch different support points of the support body 421, thereby realizing the suspension of the upper baking tray assembly 10, thereby increasing or decreasing the size of the cooking space. The principle is simple and the operation is convenient.

[0085] 3) The number of thread heads of the worm shaft 31 matches the number of teeth 4112 of the turbine 411, which simplifies the structure and saves costs. At the same time, the support body 421 can be self-locked after rotating to any angle.

[0086] 4) The support body 421 includes a first segment 4210 and a second segment 4211. The distance from the support point located at the end position close to the second end of the second segment 4211 to the axis of the transmission rod 41 is L1, and the distance from the support point located at the end position close to the first end of the second segment 4211 to the axis of the transmission rod 41 is L2. The difference between L1 and L2 is consistent with the suspension height of the grilling machine, so that the suspension height of the grilling pan assembly of the grilling machine can be set and adjusted.

[0087] 5) The thread head line of the worm rod 31 can be set as an Archimedean spiral line. The worm rod 31 can drive the turbine 411, but the turbine 411 cannot reversely drive the worm rod 31. The structure is simple to assemble, has high reliability and low cost.
