Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a drum-type stir-fry machine. Background Technology

[0002] During the cooking process of a fully automatic cooking machine, the pot is placed in the inner pot and needs to rotate. Due to manufacturing errors, the pot rotates off-center, which seriously affects the stability of the pot's rotation. This causes friction between the pot and the inner pot and other parts, resulting in damage.

[0003] Patent document CN 208491803 U discloses a roller guide structure for the pot body of an automatic cooking machine, including an inner pot and a pot body mounted on a rotating base on the bottom surface of the inner pot. Several roller devices are evenly arranged coaxially on the side wall of the inner pot. When the pot body rotates, if the pot body experiences eccentric movement, it will act on the roller devices, compressing and deforming the springs of the roller devices, applying a force in the opposite direction to the pot, forcibly reducing the pot's offset. When the pot is not eccentric, the springs return to their original position, and the entire process returns to normal, achieving the purpose of pot body eccentricity correction. Utility Model Content

[0004] The technical problem solved by this utility model is: how to make the position of the roller device adjustable in order to control the eccentricity of the pot body.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a front-end support roller for a drum cooking machine includes a roller frame, a roller body pivotally connected to the roller frame, a spring upright plate located behind the roller frame, and a spring disposed between the spring upright plate and the roller frame. The spring is used in conjunction with a guide assembly. The bottom plate of the roller frame has a long strip-shaped extension structure. The spring upright plate is fixed on an adjustment plate. The top support of the inner liner has a hinge shaft and an arc-shaped adjustment hole. The long strip-shaped extension structure and the adjustment plate are both engaged with the hinge shaft. An adjustment bolt is installed on the adjustment plate. The adjustment bolt is used in conjunction with an adjustment nut. The adjustment bolt is engaged in the adjustment hole.

[0006] The present invention relates to a drum-type stir-fry machine with several supporting rollers at the front end, distributed around the perimeter of the pot body. The roller bodies abut against the outer wall of the pot body, and the springs are compressed and deformed, giving the pot body a force in the opposite direction, thus forcibly reducing the eccentricity of the pot body.

[0007] When adjusting the pot's eccentricity, the operator loosens the adjusting bolt, causing the adjusting plate to rotate around the hinge axis. If the adjusting plate rotates towards the pot, the spring is compressed, increasing the force exerted by the roller on the pot. If the adjusting plate moves away from the pot, the spring compression decreases, reducing the force exerted by the roller on the pot. If the force exerted by the roller on one side of the pot decreases while the force on the roller on the other side increases, the pot will shift towards the side of the roller with the reduced force. This process is used to adjust the pot's eccentricity, thus controlling its movement. After adjusting the eccentricity, the operator tightens the adjusting bolt.

[0008] The roller body is pivotally connected to the roller shaft of the roller frame via a first bearing. A second bearing, a thrust ball bearing, is mounted on the roller shaft and is located between the bottom plate of the roller frame and the bottom surface of the roller body. The pot is placed in the inner liner from top to bottom. The pot exerts a downward force on the roller body, which the thrust ball bearing effectively withstands, stabilizing the roller body.

[0009] The guiding assembly includes a fixed sleeve, a guide sleeve, and a guide bolt. The fixed sleeve and guide sleeve are located between the spring upright plate and the roller frame. The guide bolt passes through the spring upright plate, guide sleeve, and fixed sleeve and is screwed together. The spring is sleeved on the fixed sleeve and guide sleeve. The front end of the compressed spring acts on the fixed sleeve, which in turn acts on the roller frame. The roller frame rotates about the hinge axis towards the pot body, and the roller body acts on the outer wall of the pot body. The pot body exerts a reaction force on the roller body, which causes the roller frame to rotate about the hinge axis away from the pot body. The spring is compressed, the fixed sleeve moves towards the guide sleeve, and the guide bolt moves with the fixed sleeve. The guide bolt moves relative to the guide sleeve, and one end of the guide bolt protrudes rearward from the spring upright plate.

[0010] A limiting component is installed on the roller frame. The front end of the limiting component is bent and connected to the roller frame by bolts. The rear end of the limiting component is bent and located behind the spring upright plate, where it abuts against the spring upright plate. When the roller frame rotates forward around the hinge axis until the rear end of the limiting component abuts against the spring upright plate, it indicates that the roller frame has reached its maximum forward rotation around the hinge axis.

[0011] A third bearing, a thrust ball bearing, is installed between the elongated extension structure and the adjusting plate, and is mounted on the hinge shaft. This third bearing not only separates the elongated extension structure from the adjusting plate vertically, but also allows both structures to rotate smoothly around the hinge shaft.

[0012] A base plate is fixed to the top support of the inner liner, located next to the adjustment hole. The adjustment plate is partially pressed against the base plate. Thus, when the operator tightens the adjustment bolt, the base plate fills the space between the adjustment plate and the top support of the inner liner, tightening the adjustment plate and stabilizing its position, preventing it from loosening.

[0029] Combination Figure 1 , Figure 5 , Figure 6The front support roller of the drum cooking machine includes a roller frame 10, a roller body 20 pivotally connected to the roller frame, a spring upright plate 30 located behind the roller frame, and a spring 40 disposed between the spring upright plate and the roller frame. The spring and the guide assembly 50 are used together. The bottom plate of the roller frame has a long strip-shaped extension structure 11. The spring upright plate is fixed on the adjustment plate 31. The top support 60 of the inner pot has a hinge shaft 61 and an arc-shaped adjustment hole 62. The long strip-shaped extension structure and the adjustment plate are both engaged with the hinge shaft. An adjustment bolt 32 is installed on the adjustment plate. The adjustment bolt and the adjustment nut 33 are used together. The adjustment bolt is engaged in the adjustment hole.

[0030] refer to Figures 5 to 7 The present invention relates to a drum-type cooking machine with two sets of front-end support rollers, two in each set, each set of which is mounted on a top bracket 60 of an inner pot. The two sets of front-end support rollers are arranged opposite to each other, and there are two top brackets 60 of the inner pot, which are arranged opposite to each other and distributed on both sides of the pot body 70.

[0031] The roller body 20 abuts against the outer wall of the pot body, and the spring 40 is compressed and deformed, giving the pot body a force in the opposite direction, forcibly reducing the eccentricity of the pot body. The eccentricity of the pot body 70 can be judged based on the gap between the outer wall of the pot body and the inner liner.

[0032] When adjusting the eccentricity of the pot body 70, the operator loosens the adjusting bolt 32, causing the adjusting plate 31 to rotate around the hinge shaft 61. If the adjusting plate 31 rotates towards the pot body 70, the spring 40 is compressed, increasing the force exerted by the roller body 20 on the pot body 70. If the adjusting plate 31 moves away from the pot body 70, the compression of the spring 40 decreases, reducing the force exerted by the roller body 20 on the pot body 70. Since the force exerted by the roller body 20 on one side of the pot body 70 decreases while the force exerted by the roller body on the other side increases, the pot body shifts towards the side of the roller body with the reduced force. In this way, the eccentricity of the pot body 70 is adjusted to control its eccentricity. After adjusting the eccentricity of the pot body, the operator tightens the adjusting bolt 32.

[0033] like Figure 3 The roller body 20 is pivotally connected to the roller shaft 12 of the roller frame via a first bearing. A second bearing 13, which is a thrust ball bearing, is mounted on the roller shaft and is located between the bottom plate of the roller frame and the bottom surface of the roller body. The pot body 70 is placed in the inner liner from top to bottom. The pot body exerts a downward force on the roller body 20, and the thrust ball bearing can effectively withstand this force, thus stabilizing the roller body.

[0034] Combination Figure 1 , Figure 2The guide assembly 50 includes a fixed sleeve 51, a guide sleeve 52, and a guide bolt 53. The fixed sleeve and guide sleeve are located between the spring upright plate 30 and the roller frame 10. The guide bolt passes through the spring upright plate 30 and is screwed to the guide sleeve and fixed sleeve. The spring 40 is sleeved on the fixed sleeve and guide sleeve. The front end of the compressed spring 40 acts on the fixed sleeve 51, and the fixed sleeve 51 acts on the roller frame 10. The roller frame rotates around the hinge axis 61 toward the pot body 70, and the roller body 20 acts on the outer wall of the pot body. The pot body has a reaction force on the roller body 20, which causes the roller frame 10 to rotate around the hinge axis 61 away from the pot body 70. The spring 40 is compressed, the fixed sleeve 51 moves toward the guide sleeve 52, and the guide bolt 53 moves with the fixed sleeve 51. The guide bolt moves relative to the guide sleeve 52, and one end of the guide bolt 53 protrudes backward from the spring upright plate 30.

[0035] like Figure 1 , Figure 2 A limiting member 14 is installed on the roller frame 10. The front end of the limiting member is bent and connected to the roller frame. The rear end 141 of the limiting member is bent and located behind the spring upright plate 30, so as to abut against the spring upright plate. When the roller frame 10 rotates forward around the hinge axis 61, it indicates that the roller frame 10 has reached its maximum forward rotation around the hinge axis 61 when the rear end of the limiting member 14 abuts against the spring upright plate 30.

[0036] A third bearing 34 is provided between the elongated extension structure 11 and the adjusting plate 31. The third bearing is mounted on the hinge shaft 61 and is a thrust ball bearing. The third bearing 34 not only separates the elongated extension structure 11 and the adjusting plate 31 vertically, but also allows the elongated extension structure and the adjusting plate to rotate smoothly around the hinge shaft 61.

[0037] like Figure 5 A base plate 63 is fixed to the top support 60 of the inner liner. The base plate is located beside the adjustment hole 62, and the adjustment plate 31 partially presses against the base plate. Thus, when the operator tightens the adjustment bolt 32, the base plate 63 fills the space between the adjustment plate 31 and the top support 60 of the inner liner, tightening the adjustment plate 31 and stabilizing its position, preventing it from loosening. The above description is only a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this utility model, there will be changes in the specific implementation and application scope. The content of this specification should not be construed as a limitation of this utility model.
