Description

Technical Field

[0001] This invention relates to the field of food production technology, and in particular to a cake-making machine. Background Technology

[0002] In the process of making the dough, flour and water need to be mixed and kneaded into a dough. During the kneading process, the operator needs to precisely control the amount of water added and the kneading force. Only after strictly controlling the amount of water added and mixing the flour and water evenly can a qualified dough be obtained.

[0003] During the dough production process, even experienced operators may make mistakes such as adding too little or too much water after kneading the dough multiple times, or fatigue may prevent the flour and water from being fully mixed and causing the dough to clump together. Ultimately, the dough cannot be kneaded into a qualified dough, resulting in reduced efficiency in making the dough. Summary of the Invention

[0004] The main objective of this invention is to provide a pancake-making machine that aims to improve the yield rate of pancakes and increase the efficiency of pancake production.

[0005] To achieve the above objectives, the present invention provides a cake-making machine comprising:

[0006] case;

[0007] A stirring mechanism, comprising a stirring chamber disposed within the housing, a sealing member for closing the bottom opening of the stirring chamber, and a stirring member rotatably disposed within the stirring chamber;

[0008] A feeding mechanism, located within the housing, includes a feeding hopper and a feeding switch. The feeding hopper stores the liquid required for cake making, and the feeding switch controls the connection and disconnection between the feeding hopper and the mixing chamber.

[0009] The timing structure, located within the housing, includes a reversible output gear, a drive gear, a distribution gear, and a first functional gear, a second functional gear, and a third functional gear arranged sequentially around the distribution gear in the circumferential direction. The output gear engages with the drive gear. The first functional gear is connected to the sealing member, the second functional gear is connected to the feeding switch, and the third functional gear is connected to the stirring member.

[0010] When the drive gear rotates forward to drive the distribution gear, the distribution gear intermittently drives the first functional gear, the second functional gear, and the third functional gear in sequence, thereby sequentially realizing the sealing component blocking the mixing chamber, the feeding switch connecting the feeding chamber and the mixing chamber, and the stirring component moving up and down within the mixing chamber;

[0011] When the drive gear reverses and drives the distribution gear, the distribution gear intermittently drives the third functional gear, the second functional gear, and the first functional gear in sequence, thereby sequentially realizing the lifting and lowering of the stirring component in the stirring chamber, the material supply switch separating the material supply chamber from the stirring chamber, and the disengaging of the sealing component from the stirring chamber.

[0012] Optionally, the time T1 for the distribution gear to rotate between the first functional gear and the second functional gear and the time T2 for the distribution gear to rotate between the second functional gear and the third functional gear satisfy the following relationship: the ratio of T1 to T2 is 1:2 to 1:1.

[0013] Optionally, the distribution gear has at least three teeth, with the first tooth and the last tooth located at opposite ends, and the middle tooth located between the first tooth and the last tooth. The tooth height of the first tooth and the tooth height of the last tooth are both greater than the tooth height of the middle tooth.

[0014] Optionally, the central angle corresponding to the arc formed between the first tooth and the last tooth ranges from 20 degrees to 40 degrees.

[0015] Optionally, the drive gear rotates coaxially with the distribution gear, and the drive gear meshes with the output gear of the power source.

[0016] Optionally, the toothed portion of the drive gear and the toothed portion of the distribution gear do not overlap in the vertical direction.

[0017] Optionally, the toothed portion of the drive gear occupies at least two-thirds of the circumference of the drive gear.

[0018] Optionally, both ends of the toothed portion of the drive gear are provided with guide structures, and the guide structures have a guide state and a avoidance state; when the guide structure is in the guide state, the output gear synchronously drives the drive gear to rotate; when the guide structure is in the avoidance state, the output gear cannot drive the drive gear to rotate.

[0019] Optionally, when the output gear rotates forward, the guide structure is in the guide state; when the output gear rotates in reverse, the guide structure is in the avoidance state.

[0020] Optionally, the cake maker has a stirring state; when the cake maker is in the stirring state, the output gear rotates forward and reverse cyclically to drive the distribution gear to drive the third functional gear to rotate forward and reverse cyclically.

[0021] This invention employs a timing structure to control the mixing and feeding mechanisms, enabling the dough maker to more precisely control the mixing and feeding processes, ultimately producing qualified dough for use by other mechanisms. Specifically, the timing structure includes an output gear, a drive gear, a distribution gear, a first functional gear, a second functional gear, and a third functional gear. The output gear can mesh with the drive gear in both forward and reverse directions, while the drive gear is linked with the distribution gear. The first, second, and third functional gears are sequentially arranged around the distribution gear in the circumferential direction. The rotation of the distribution gear sequentially drives the first, second, and third functional gears. The first functional gear is connected to a sealing component, rotating through the distribution gear and meshing with it. The sealing component blocks or moves away from the bottom opening of the mixing chamber. The second functional gear is connected to the feeding switch, rotating through the distribution gear and meshing with it. The feeding switch connects or disconnects the feeding chamber and the mixing chamber. The third functional gear is connected to the mixing component, rotating through the distribution gear and meshing with it. The mixing component mixes the dough within the mixing chamber. In this way, the invention can knead flour into qualified dough by distributing gears to drive the first functional gear, the second functional gear and the third functional gear respectively, and the mechanical and gear drive can greatly improve the production efficiency of dough.

[0039] This invention proposes a cake-making machine.

[0040] Reference Figures 1 to 9 In one embodiment of the present invention, the cake-making machine includes:

[0041] Casing 100;

[0042] The stirring mechanism 200 includes a stirring chamber 210 disposed within the housing 100, a sealing member 220 for closing the bottom opening of the stirring chamber 210, and a stirring member 230 rotatably disposed in the stirring chamber 210.

[0043] A feeding mechanism 300 is disposed in the housing 100. The feeding mechanism 300 includes a feeding bin 320 and a feeding switch 310. The feeding bin 320 stores the liquid required for cake making, and the feeding switch 310 controls the connection and disconnection between the feeding bin 320 and the mixing bin 210.

[0044] A timing structure 400, disposed within the housing 100, includes a reversible output gear 410, a drive gear 420, a distribution gear 430, and a first functional gear 440, a second functional gear 450, and a third functional gear 460 arranged sequentially around the distribution gear 430 in the circumferential direction. The output gear 410 is driven to mesh with the drive gear 420. The first functional gear 440 is connected to the sealing member 220, the second functional gear 450 is connected to the feeding switch 310, and the third functional gear 460 is connected to the stirring member 230.

[0045] When the drive gear 420 rotates forward to drive the distribution gear 430, the distribution gear 430 intermittently drives the first functional gear 440, the second functional gear 450 and the third functional gear 460 in sequence, thereby realizing the sealing component 220 sealing the mixing chamber 210, the feeding switch 310 connecting the feeding chamber 320 and the mixing chamber 210, and the stirring component 230 moving up and down within the mixing chamber 210;

[0046] When the drive gear 420 reverses to drive the distribution gear 430, the distribution gear 430 intermittently drives the third functional gear 460, the second functional gear 450 and the first functional gear 440 in sequence, thereby realizing the lifting and lowering of the stirring component 230 in the stirring chamber 210, the separation of the feeding chamber 320 and the stirring chamber 210 by the feeding switch 310, and the disengagement of the sealing component 220 from the stirring chamber 210.

[0047] The technical solution of this invention employs a timing structure 400 to control the mixing mechanism 200 and the feeding mechanism 300 in a specific time sequence. This allows the dough maker to more precisely control the mixing and feeding processes of the dough, ultimately obtaining qualified dough for use by other mechanisms. Specifically, the timing structure 400 includes an output gear 410, a drive gear 420, a distribution gear 430, a first functional gear 440, a second functional gear 450, and a third functional gear 460. The output gear 410 can mesh with the drive gear 420 in both forward and reverse directions, while the drive gear 420 is linked with the distribution gear 430. The first functional gear 440, the second functional gear 450, and the third functional gear 460 are arranged sequentially around the circumferential direction of the distributing gear 430. The rotation of the distributing gear 430 drives the first functional gear 440, the second functional gear 450, and the third functional gear 460 in sequence. The first functional gear 440 is connected to the sealing member 220 and rotates through the distributing gear 430. The sealing member 220 blocks or moves away from the bottom opening of the mixing chamber 210. The second functional gear 450 is connected to the feeding switch 310 and rotates through the distributing gear 430. The feeding switch 310 connects or disconnects the feeding chamber 320 and the mixing chamber 210. The third functional gear 460 is connected to the mixing member 230 and rotates through the distributing gear 430 and the third functional gear 460. The mixing member 230 mixes the dough in the mixing chamber 210. In this way, in this invention, the distribution gear 430 drives the first functional gear 440, the second functional gear 450 and the third functional gear 460 respectively, which can knead flour into qualified dough. Moreover, the mechanical and gear drive can greatly improve the production efficiency of dough.

[0048] Furthermore, the specific process of timing control includes two steps: a preparation step before the kneading step, which includes closing the mixing chamber 210 and adding water and oil; and a processing step after kneading, which includes stopping the addition of water and oil and opening the mixing chamber 210. In the first step, the output gear 410 drives the distribution gear 430 to rotate forward, which in turn drives the distribution gear 430 to sequentially drive the first functional gear 440, the second functional gear 450, and the third functional gear 460. During the forward rotation of the drive gear 420, the distribution gear drives the first functional gear 440 to block the bottom opening of the mixing chamber 210 by the sealing component 220. The distribution gear 430 drives the second functional gear 450 to connect the feed switch 310 to the feed chamber 320 and the mixing chamber 210, thereby allowing the oil and water in the feed chamber 320 to smoothly enter the mixing chamber 210 and mix with the dough in the mixing chamber 210. The distribution gear 430 drives the third functional gear 460 to make the mixing component 230 rotate and stir in the first direction in the mixing chamber 210. The output gear 410 drives the distribution gear 430 to reverse, thereby driving the distribution gear 430 to drive the third functional gear 460, the second functional gear 450 and the first functional gear 440 in sequence. During the reverse rotation of the drive gear 420, the distribution gear 430 drives the third functional gear 460 to cause the stirring component 230 to rotate and stir in the second direction within the stirring chamber 210. The distribution gear 430 drives the second functional gear 450 to cause the feed switch 310 to block the feed chamber 320 and the stirring component, thereby stopping the feed chamber 320 from supplying water and oil to the stirring chamber 210. The distribution gear 430 drives the third functional gear to move the sealing component 220 away from the bottom opening of the stirring chamber 210, thereby allowing the dough to be discharged for processing by the dough-making structure of the dough-making machine.

[0049] It should be noted that the first and second stirring directions described above are opposite to each other. In this embodiment, the distribution gear 430, the drive gear 420, the first functional gear 440, the second functional gear 450, and the third functional gear 460 are all externally meshing incomplete gears. In this embodiment, by adopting an incomplete gear meshing structure, the timing control is more precise, allowing for more accurate control of the meshing timing between different functional gears, as well as the duration of meshing between the distribution gear 430 and the functional gears. Furthermore, by replacing different distribution gears 430 or functional gears, the meshing ratio between different gears can be achieved, thereby adjusting the oil and water intake, as well as the stirring timing. In other words, this embodiment also has better adjustment capabilities.

[0050] Furthermore, the time T1 during which the distribution gear 430 rotates between the first functional gear 440 and the second functional gear 450, and the time T2 during which the distribution gear 430 rotates between the second functional gear 450 and the third functional gear 460, satisfy the following relationship: the ratio of T1 to T2 is 1:2 to 1:1. Specifically, in one embodiment, the angle through which the trigger structure of the distribution gear 430 rotates from the position of the first functional gear 440 to the position of the second functional gear 450 is 59 degrees, and the angle through which the trigger structure of the distribution gear 430 rotates from the position of the second functional gear 450 to the position of the third functional gear 460 is 91 degrees. That is, when the rotational speed of the distribution gear 430 is a constant value, the time T1 for the trigger structure of the distribution gear 430 to rotate between the first functional gear 440 and the time T2 for the distribution gear 430 to rotate between the second functional gear 450 and the third functional gear 460 satisfies the following relationship: the ratio of T1 to T2 is 1:2.

[0051] In one embodiment, the distribution gear 430 has at least three teeth: a first tooth 431 and a last tooth 433 located at opposite ends, and a middle tooth 432 located between the first tooth 431 and the last tooth 433. The tooth height of both the first tooth 431 and the last tooth 433 is greater than the tooth height of the middle tooth 432. By setting the tooth height of the first tooth 431 of the distribution gear 430 to be greater than that of the middle tooth 432, when the distribution gear 430 rotates forward, the first tooth 431 is the first to engage with other functional gears, and the advantage of its higher tooth height allows for more accurate meshing of the distribution gear 430 with other functional gears. Similarly, when the distribution gear 430 rotates in reverse, the last tooth 433 is the first to engage with other functional gears, so its tooth height needs to be set to be greater than that of the middle tooth 432. Additionally, it should be noted that the arc-shaped tooth tip design of the middle gear 432 effectively reduces the friction between the tooth tip of the distribution gear 430 and the tooth root of other functional gears, thereby ensuring smooth meshing of the distribution gear 430 with other functional gears. These other functional gears include, but are not limited to, the first functional gear 440, the second functional gear 450, and the third functional gear 460.

[0052] Furthermore, the central angle corresponding to the arc formed between the first tooth 431 and the last tooth 433 ranges from 20 degrees to 40 degrees. Specifically, in this embodiment, the distribution gear 430 is provided with a triggering structure, which includes a first tooth 431, a middle tooth 432, and a last tooth 433. When the triggering structure of the distribution gear 430 meshes with the functional gear, the functional gear can continuously rotate within the central angle corresponding to the arc formed between the first tooth 431 and the last tooth 433, thereby driving the mechanism corresponding to the functional gear to work. In this embodiment, the central angle corresponding to the arc formed between the first tooth 431 and the last tooth 433 ranges from 20 degrees to 40 degrees. In one embodiment, when the required rotation time of the functional gear is short, the central angle corresponding to the arc formed between the first tooth 431 and the last tooth 433 can be taken as 20 degrees. When the required rotation time of the functional gear is longer, the central angle corresponding to the arc formed between the first tooth 431 and the last tooth 433 can be taken as 40 degrees. In other embodiments, other ranges of values ​​can be taken according to the required rotation time and angle of the functional gear. However, it should be noted that the minimum value cannot be zero degrees and the maximum should not exceed 120 degrees. If the value exceeds 120 degrees, it may cause oil and water to enter when the sealing component 220 fails to seal the bottom opening of the mixing chamber 210, eventually causing oil and water to flow out of the mixing chamber 210.

[0053] In one embodiment, the drive gear 420 and the distribution gear 430 rotate coaxially, and the drive gear 420 meshes with the output gear 410 of the power source. In another embodiment, the drive gear 420 and the distribution gear 430 may also be configured to drive each other.

[0054] Furthermore, the toothed portions of the drive gear 420 and the toothed portions of the distribution gear 430 do not overlap in the vertical direction. The toothed portion of the drive gear 420 generally meshes with the output gear 410, and the rotation of the output gear 410 drives the drive gear 420 to rotate. The toothed portion of the distribution gear 430 needs to mesh sequentially with the first functional gear 440, the second functional gear 450, and the third functional gear 460. Therefore, the first functional gear 440, the second functional gear 450, and the third functional gear 460 are arranged sequentially around the distribution gear 430. To avoid structural interference between the output gear 410 and other functional gears, the toothed portions of the drive gear 420 and the distribution gear 430 are positioned to avoid each other, thus allowing the entire timing structure 400 to occupy as little space as possible while satisfying the basic operating principles.

[0055] Furthermore, the toothed portion of the drive gear 420 occupies at least two-thirds of its circumference. It should be noted that the larger the toothed portion of the drive gear 420 occupies of its circumference, the greater the range of rotation that the entire drive gear 420 can achieve. To meet the required rotation angle for the drive gear 420 to drive the coaxial distribution gear 430 from the first functional gear 440 to the second functional gear 450, and then to the third functional gear 460, the toothed portion of the drive gear 420 must be at least two-thirds of its circumference.

[0056] Furthermore, to prevent the output gear 410 from over-rotating, both ends of the toothed portion of the drive gear 420 are provided with guide structures 500. The guide structures 500 have a guide state and a avoidance state. When the guide structure 500 is in the guide state, the output gear 410 synchronously drives the drive gear 420 to rotate; when the guide structure 500 is in the avoidance state, the output gear 410 cannot drive the drive gear 420 to rotate. It should be noted that, in this embodiment, reference... Figure 3 and Figure 9 The guide structure 500 includes a spring 510 and a locking member 520. When the guide structure 500 is in the guide state, the output gear 410 can maintain contact with the locking member 520, thereby driving the drive gear 420 with the guide structure 500 to rotate. When the guide structure 500 is in the avoidance state, the locking member 520 will squeeze the spring 510 during the rotation of the output gear 410, thereby avoiding the rotation. In this way, the output gear 410 will continue to spin freely and cannot drive the drive gear 420 with the guide structure 500 to rotate.

[0057] In one embodiment, when the output gear 410 rotates clockwise, the guide structure 500 is in a guide state; when the output gear 410 rotates counterclockwise, the guide structure 500 is in a avoidance state. In another embodiment, when the output gear 410 rotates counterclockwise, the guide structure 500 is in a avoidance state; when the output gear 410 rotates clockwise, the guide structure 500 is in a guide state. It should be noted that in this embodiment, clockwise rotation is clockwise, and counterclockwise rotation is counterclockwise. However, this design is not limited to this; in other embodiments, clockwise rotation can be counterclockwise, and counterclockwise rotation can be clockwise.

[0058] Furthermore, in one embodiment, the dough maker has a stirring state; when the dough maker is in the stirring state, the output gear 410 rotates forward and reverse cyclically to drive the distribution gear 430 to drive the third functional gear 460 to rotate forward and reverse cyclically. Specifically, the output gear 410 rotates forward and reverse cyclically to drive the drive gear 420 to rotate in both directions, which in turn drives the distribution gear 430, which is linked to the drive gear 420, to rotate repeatedly. Ultimately, this causes the third functional gear 460, which is driven by the stirring element 230, to rotate repeatedly, thereby enabling the stirring element 230 to reciprocate within the stirring chamber 210 to stir the dough. It should be noted that the stirring state setting allows the dough in the stirring chamber 210 to be fully mixed with water and oil, thereby improving the dough yield and increasing the production efficiency of the dough.
