Description

Technical Field

[0001] The invention relates to the technical field of steaming and baking cooking machines, in particular to an inner pot component and a steaming and baking cooking machine. Background Art

[0002] The inner pot of the steam-bake cooking machine usually adopts the form of fixing the baking tray or grill with side ribs to reduce the assembly process and improve production efficiency. In order to ensure the structural strength of the inner pot and the integrity of the inner pot itself, the side ribs are usually formed by stretching. In actual use, the baking tray and grill will be stuck to the side wall of the inner pot due to their own thermal expansion, resulting in scratches on the coating on the surface of the inner pot side wall when the baking tray and grill are removed.

[0003] The existing technical solutions generally adopt the method of reserving design gaps to reduce the above-mentioned jamming phenomenon. However, the reserved design gap needs to be tested through a large number of tests, and the test cost during design is increased by simulating different cooking conditions of users. When the reserved design gap increases, the height of the side ribs also needs to be increased accordingly to ensure that the baking tray or grill will not slip off the side ribs. However, the height of the side ribs cannot be increased infinitely. The current mainstream material of the inner pot is SUS304 / t0.7. If the height of the side ribs is to reach the range of 7mm to 9mm, secondary stretch forming is required. During this process, the thickness of the side ribs at the bend becomes thinner and is prone to breakage. This greatly increases the difficulty of production and reduces the product yield during the production of the inner pot. If the height of the side ribs is to be further increased, more simulation tests and experimental tests are required, which undoubtedly increases the design cost. Summary of the invention

[0004] Since the existing steam-bake cooking machine has the disadvantage of low yield due to the problem of jamming and the limitation of the inner pot manufacturing process, it is necessary to provide an inner pot assembly and a steam-bake cooking machine.

[0005] Inner pot assembly, for steam-bake cooking machine, comprising:

[0006] An inner pot body, the inner pot body having two elastic walls arranged opposite to each other, the middle part of the elastic wall being concave to form side ribs for supporting the storage rack of the steam-bake cooking machine; and

[0007] A driving member is drivingly connected to the elastic wall and is used to drive one of the two elastic walls to deform in a direction close to or away from the other elastic wall so as to adjust the gap between the elastic wall and the rack.

[0008] With such arrangement, the middle parts of the two elastic walls are stretched and deformed in directions away from each other by the driving member, so that a gap can be left between the elastic wall and the storage rack, thereby facilitating the removal of the storage rack from the inner pot without scratching the inner wall of the inner pot. Since there is no need to adjust the stretching height of the side ribs, the production difficulty of the inner pot body is reduced, the yield rate of the inner pot body is improved, and it is also beneficial to eliminate assembly errors caused by insufficient precision of the production molds of the storage rack and the inner pot body. In addition, during maintenance, it is convenient for technicians to solve the problem of different models of storage racks being incompatible by manual fine-tuning, rather than having to return the machine to the factory for repair, which is beneficial to reducing the return rate of the steam-bake cooking machine for repair.

[0009] In one embodiment, the driving member includes a pull plate fixedly connected to the middle portion of the elastic wall, a traction rope limitedly connected to the pull plate, and a pull rope motor drivingly connected to the traction rope.

[0010] With such an arrangement, a traction rope is used to transmit the pulling force of the rope-pulling motor, ensuring that the elastic wall is only stretched toward the outside of the inner liner body. When the elastic wall of the inner liner body needs to be restored to its original state, the rope-pulling motor is reversed to loosen the traction rope. There is no need to consider the number of turns of the rope-pulling motor reversal, that is, there is no need to consider quantitatively adjusting the telescopic length of the traction rope, thereby simplifying the operation difficulty.

[0011] In one embodiment, the pulling plate has a plurality of pulling points, the number of the pulling ropes is multiple and each of the pulling ropes corresponds one-to-one to each of the pulling points.

[0012] With such arrangement, the pull plate itself is not prone to large deformation, thereby ensuring that the deformation difference of the elastic wall at multiple pulling points is small and the elastic wall deforms evenly as a whole, preventing the inner liner from being damaged due to excessive tension locally.

[0013] In one of the embodiments, there are a plurality of side ribs and they are arranged in sequence and at intervals along the vertical direction of the inner liner body, and there are a plurality of pull plates and each of the pull plates is located between two adjacent side ribs.

[0014] Such an arrangement maintains the consistency of deformation of the elastic wall, which helps to prevent the elastic wall from being damaged due to uneven deformation.

[0015] In one of the embodiments, the plurality of traction points are arranged in sequence along an arrangement direction inclined to the vertical direction.

[0016] Such an arrangement expands the arrangement range of the traction point, making the overall deformation of the elastic wall more uniform.

[0017] In one embodiment, the pull-wire motor is fixed to the outer edge of the elastic wall.

[0018] This arrangement reduces the overall space occupied by the inner liner assembly and shortens the length of the traction rope. In addition, the edge portion of the elastic wall that is not easily deformed is used as the fulcrum of the rope-pulling motor, without the need for other structures, thereby simplifying the structure of the inner liner assembly.

[0019] In one embodiment, the inner liner assembly also includes a guide member fixed to the elastic wall and having a rope threading hole, the traction rope is passed through the rope threading hole, and the distance between the rope threading hole and the elastic wall is greater than the distance between the side of the pull plate facing away from the elastic wall and the elastic wall.

[0020] With such arrangement, the guide member provides support for the traction rope and increases the force arm of the traction rope on the pulling plate, thereby reducing the required driving force of the rope pulling motor.

[0021] In one embodiment, there are multiple pull plates, the number of the rope threading holes is the same as the number of the pull plates and each rope threading hole corresponds one-to-one to each pull plate, and the interval between two adjacent rope threading holes is the same as the interval between two adjacent pull plates.

[0022] Such an arrangement ensures that the pulling forces on different pulling plates are in the same direction, so that the elastic wall is deformed evenly.

[0023] In one embodiment, there are two rope-pulling motors, which are respectively located on two sides of the pull plate.

[0024] With this arrangement, the two pull rope motors pull the pull plate from both sides respectively, and the forces on both sides of the pull plate are balanced, so that the deformation direction of the middle part of the elastic wall is perpendicular to the outer side surface of the elastic wall, thereby avoiding the middle part of the elastic wall from tilting toward one side when deforming.

[0025] The present application also provides a steaming and baking cooking machine, comprising:

[0026] The liner assembly as described above; and

[0027] A storage rack is placed on the side ribs of the inner liner assembly, and a reserved design gap is provided between the storage rack and the elastic wall of the inner liner assembly.

[0028] With such an arrangement, in actual use, when the storage rack expands due to heat, the driving member can be used to expand the elastic wall of the inner pot body outward to avoid a reduction in the reserved design gap. In other words, when the steam-bake cooking machine finishes cooking, the driving member can actively stretch the elastic wall to increase the reserved design gap, thereby facilitating the removal of the storage rack.

[0041] The inner pot of the steam-bake cooking machine usually adopts the form of fixing the baking tray or grill with side ribs to reduce the assembly process and improve production efficiency. In order to ensure the structural strength of the inner pot and the integrity of the inner pot itself, the side ribs are usually formed by stretching. In actual use, the baking tray and grill will be stuck to the side wall of the inner pot due to their own thermal expansion, resulting in scratches on the coating on the surface of the inner pot side wall when the baking tray and grill are removed.

[0042] The existing technical solutions generally adopt the method of reserving design gaps to reduce the above-mentioned jamming phenomenon. However, the reserved design gap needs to be tested through a large number of tests, and the test cost during design is increased by simulating different cooking conditions of users. When the reserved design gap increases, the height of the side ribs also needs to be increased accordingly to ensure that the baking tray or grill will not slip off the side ribs. However, the height of the side ribs cannot be increased infinitely. The current mainstream material of the inner pot is SUS304 / t0.7. If the height of the side ribs is to reach the range of 7mm to 9mm, secondary stretch forming is required. During the stretching and forming of the side ribs, the thickness of the side ribs becomes thinner at the bend and is prone to breakage, which greatly increases the difficulty of production and reduces the product yield during the production of the inner pot. If the height of the side ribs is to be further increased, more simulation tests and experimental tests are required, which undoubtedly increases the design cost.

[0043] See also Figure 1 , Figure 3 and Figure 4 , Figure 1 A schematic diagram of the structure of the liner assembly provided in this application; Figure 3 for Figure 1 A front view of the inner tank body 10, Figure 4 for Figure 3 The enlarged partial view of the inner liner body 10 at Y is shown. It is worth noting that in order to avoid stress concentration of the side ribs 12 during the stretching process, the corners of the side ribs 12 themselves and the intersection of the side ribs 12 and the elastic wall 11 are respectively provided with chamfers 121, which results in the effective length of the side ribs 12 that can be used to support the rack being reduced, making the reserved design gap difficult to achieve. For example, if the height of the side ribs 12 is 8mm and the length of the chamfers 121 is 2mm, then the effective length of the side ribs 12 that can be used to support the rack is 4mm. Considering that the rack needs to be prevented from falling when sliding, an additional safety distance of 2mm is required, which further compresses the effective length. At this point, the reserved design gap is only 2mm. Considering the production error of the inner liner body 10 or the rack, the deformation of the elastic wall 11 during transportation and other influencing factors, these factors will further compress the size of the reserved design gap, or even completely occupy the reserved design gap. The final consequence is that the quality of the product is reduced, affecting the customer's experience.

[0044] See also Figure 4 Furthermore, the inner tank assembly also includes a limiting rib 13 extending inward from the side rib 12. The limiting rib 13, the side rib 12 of the next layer and the elastic wall 11 together form a receiving groove 14 for accommodating the end of the storage rack. During actual use, the storage rack is deformed by heat and the chamfer 121 is easily accumulated, causing the side rib 12 and the limiting rib 13 to be deformed and damaged.

[0045] Based on this, it is necessary to provide an inner pot assembly and a steam-bake cooking machine that can solve the problem of sticking and avoid a decrease in the inner pot manufacturing yield.

[0046] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the inner tank assembly provided in this application. Figure 2 for Figure 1 The front view of the inner pot assembly is shown. Specifically, the inner pot assembly provided by the present application includes an inner pot body 10 and a driving member 20, the inner pot body 10 has two elastic walls 11 arranged opposite to each other, the middle part of the elastic wall 11 is concave to form a side rib 12 for supporting the storage rack of the steam-bake cooking machine, and the driving member 20 is drivingly connected to the elastic wall 11 to drive one of the two elastic walls 11 to deform in a direction close to or away from the other elastic wall 11 to adjust the gap between the elastic wall 11 and the storage rack. In other words, the driving member 20 drives any one or both elastic walls 11 of the inner pot body 10 to expand outward, so that the inner pot body 10 can not only accommodate the storage rack, but also allow the storage rack to enter and exit freely. The middle parts of the two elastic walls 11 are stretched and deformed in a direction away from each other by the driving member 20, so that a sufficient gap can be left between the elastic wall 11 and the storage rack, thereby facilitating the removal of the storage rack from the inner pot without scratching the inner wall of the inner pot. Since there is no need to adjust the stretching height of the side ribs 12, the production difficulty of the inner pot body 10 is reduced, the yield rate of the inner pot body 10 is improved, and it is also beneficial to eliminate the assembly error caused by the insufficient precision of the production molds of the storage rack and the inner pot body 10; in addition, during maintenance, it is convenient for technicians to solve the problem of different models of storage racks being incompatible by manual fine-tuning, rather than only being able to solve it by returning to the factory for repair, which is beneficial to reducing the return rate of the steam-bake cooking machine.

[0047] Specifically, in this embodiment provided by the present application, the driving member 20 includes a pull plate 23, a traction rope 22 and a pull rope motor 21, the pull plate 23 is fixedly connected to the middle part of the elastic wall 11, the traction rope 22 is limitedly connected to the pull plate 23, and the pull rope motor 21 is drivingly connected to the traction rope 22. Since the traction rope 22 can only transmit tension, the elastic wall 11 will only be subjected to the stretching effect toward the outside of the inner liner body 10. Therefore, when the elastic wall 11 of the inner liner body 10 needs to be restored to its original state, the pull rope motor 21 is reversed to make the traction rope 22 soft, without considering the number of turns of the pull rope motor 21 reversal, that is, without considering the quantitative adjustment of the telescopic length of the traction rope 22, which simplifies the difficulty of operation. It can be understood that if it is only to achieve the deformation of the middle part of the elastic wall 11, the traction rope 22 can also be replaced by a rigid structure such as a transmission rod and a lever assembly.

[0048] Furthermore, in an embodiment provided in the present application, the pull plate 23 has a plurality of traction points 231, and the number of the traction ropes 22 is multiple and each traction rope 22 corresponds to each traction point 231. In this way, the pull plate 23 itself is not easy to produce a large deformation, thereby ensuring that the deformation difference of the elastic wall 11 at the plurality of traction points 231 is small, and the elastic wall 11 is uniformly deformed as a whole, that is, the middle part of the inner side of the elastic wall 11 will not produce a visible depression due to the driving action of the driving member 20, which can also prevent the inner liner from being damaged due to excessive tension locally.

[0049] Furthermore, in this embodiment provided by the present application, there are multiple side ribs 12 and they are arranged in sequence along the vertical direction of the inner liner body 10, and there are multiple pull plates 23 and each pull plate 23 is located between two adjacent side ribs 12. This can ensure the consistency of the deformation of the elastic wall 11, especially the deformation of the elastic wall 11 at different side ribs 12, which is conducive to preventing the elastic wall 11 from being damaged due to its own uneven deformation.

[0050] Optionally, in an embodiment provided by the present application, a plurality of traction points 231 are sequentially arranged along an arrangement direction inclined to the vertical direction, so that a mesh structure can be formed between the traction points 231 of different pull plates 23, thereby expanding the range of action of the traction points 231 and making the overall deformation of the elastic wall 11 more uniform. Preferably, in this embodiment provided by the present application, a plurality of traction points 231 located on different pull plates 23 are arranged in an array, so that force analysis and simulation are convenient during design, and technicians are also convenient to operate during assembly and maintenance.

[0051] Optionally, in this embodiment provided by the present application, the pull-wire motor 21 is fixedly mounted on the outer edge of the elastic wall 11. This reduces the overall space occupied by the inner liner assembly, and the length of the traction rope 22 is also shorter. In addition, the pull-wire motor 21 uses the edge portion of the elastic wall 11 that is not easily deformed as a fulcrum, without the need for other structures, thereby simplifying the structure of the inner liner assembly. Specifically, the inner liner body 10 extends from the edge of the elastic wall 11 to form a mounting plate 15, and the pull-wire motor 21 is fixedly connected to the mounting plate 15. In this way, the mounting plate 15 further enhances the structural strength of the edge portion of the elastic wall 11, and can ensure that the fulcrum of the elastic wall 11 will not be greatly deformed due to the operation of the pull-wire motor 21. Specifically, the mounting plate 15 includes a connecting portion 151 and a bending portion 152. The connecting portion 151 extends from the edge of the elastic wall 11 in a direction perpendicular to the outer side surface of the elastic wall 11, and the bending portion 152 extends from a side of the connecting portion 151 away from the elastic wall 11 in a direction parallel to the outer side surface of the elastic wall 11. The pull rope motor 21 is fixedly connected to the connecting portion 151. The mounting plate 15 also has a bolt hole 153 located at the bending portion 152. The bolt hole 153 is used to cooperate with a fastening bolt to install the inner tank body 10 to the outer shell.

[0052] Further, in this embodiment provided by the present application, the liner assembly further includes a guide member 30 fixed to the elastic wall 11 and having a rope threading hole 31, the traction rope 22 is threaded through the rope threading hole 31, and the distance between the rope threading hole 31 and the elastic wall 11 is greater than the distance between the side of the pull plate 23 facing away from the elastic wall 11 and the elastic wall 11, that is, viewed from a direction perpendicular to the elastic wall, the height of the rope threading hole 31 is greater than the height of the traction point 231. In this way, the guide member 30 provides support for the traction rope 22, increases the force arm of the traction rope 22 on the pulling force of the pull plate 23, and reduces the required driving force of the rope pulling motor 21.

[0053] Optionally, in this embodiment provided by the present application, there are multiple pull plates 23, the number of rope threading holes 31 is the same as the number of pull plates 23, each rope threading hole 31 corresponds to each pull plate 23, and the interval between two adjacent rope threading holes 31 is the same as the interval between two adjacent pull plates 23. This ensures that the pulling forces on different pull plates 23 are in the same direction, so that the elastic wall 11 is deformed evenly.

[0054] Preferably, in an embodiment provided in the present application, there are two pull-wire motors 21, which are respectively located on both sides of the pull plate 23. The pull plate 23 is pulled from both sides of the pull plate 23 by two pull-wire motors 21, and the forces on both sides of the pull plate 23 are balanced, so that the deformation direction of the middle part of the elastic wall 11 is perpendicular to the outer side of the elastic wall 11, thereby preventing the middle part of the elastic wall 11 from tilting toward one side when deforming. It is understandable that the number of the pull-wire motors 21 can also be three or more, as long as the forces on both sides of the pull plate 23 can be balanced.

[0055] The present application also provides a steam-bake cooking machine, comprising the above-mentioned inner pot assembly and a storage rack placed on the side ribs 12 of the inner pot assembly. In actual use, when the storage rack expands due to heat, the elastic wall 11 of the inner pot body 10 can be expanded outward by the driving member 20 to avoid the reduction of the reserved design gap. In other words, when the steam-bake cooking machine finishes cooking, the elastic wall 11 is actively stretched by the driving member 20 to increase the reserved design gap, thereby facilitating the removal of the storage rack.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
