Description

Technical Field

[0001] This utility model relates to the field of cooking machines, and in particular to an automatic feeding mechanism for cooking machines and a cooking machine. Background Technology

[0002] Traditional cooking methods typically involve manual operation, using cooking utensils to cook ingredients. This method is inefficient and labor-intensive. Automatic cooking machines can automatically stir-fry ingredients, reducing manual operation. For example, Chinese utility model patent ZL202421002906.2 (authorization announcement number CN222443817U) discloses an automatic cooking machine, including a base, a wok, a mounting base, a flipping arm, a first lid, a drive device, a stirring robot, a detection switch, and control components. The drive device drives the stirring robot to stir-fry the dishes.

[0003] The proper dispensing of solid seasonings is one of the problems that automatic cooking machines need to solve. Currently, most automatic cooking machines liquefy solid seasonings with water before adding them to the pot. However, liquefied solid seasonings do not conform to traditional cooking habits and also add extra water to the dish, resulting in poor appearance and taste. Furthermore, some machines place solid seasonings directly above the pot, allowing them to fall into the pot under their own weight. However, with the outlet of the solid seasonings directly above the pot, the water vapor generated during heating is easily absorbed by the solid seasonings, causing them to become damp and clump. Placing the solid seasonings below the pot opening (usually on the countertop) not only conforms to traditional cooking habits but also prevents them from becoming damp and clump due to water vapor generated during cooking. However, how to automatically transport the solid seasonings below the pot opening upwards and accurately dispense them into the pot remains a challenge. Therefore, existing automatic dispensing mechanisms for solid seasonings need further improvement. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is to provide an automatic feeding mechanism for a stir-fry machine that can automatically transport solid seasonings located below the opening of the pot to the opening of the pot, in contrast to the prior art.

[0005] The second technical problem to be solved by this utility model is to provide an automatic feeding mechanism for a stir-fry machine that can automatically transport solid seasonings located below the pot opening to the pot opening and accurately put them into the pot, in contrast to the prior art.

[0006] The third technical problem to be solved by this utility model is to provide a cooking machine with the above-mentioned automatic feeding mechanism, in contrast to the prior art.

[0007] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is: an automatic feeding mechanism for a cooking machine, characterized in that it includes:

[0008] Screw, extending vertically;

[0009] A first drive structure is used to drive the screw to rotate around its own axis, and includes a first drive motor;

[0010] The feeding arm is horizontally set up, with a receiving box at one end and a screw sleeve at the other end. The screw sleeve is threadedly connected to the screw rod. When the screw sleeve is located at the lower end of the screw rod, the feeding arm is in the receiving position, and when it is located at the upper end of the screw rod, the feeding arm is in the feeding position.

[0011] The limiting component is used to radially limit the screw sleeve and the screw, so that when the feeding arm is in the receiving position, the receiving box and the discharge port of the storage device are vertically opposite each other, and when the feeding arm is in the feeding position, the receiving box and the opening of the pot are vertically opposite each other.

[0012] The second drive structure is used to drive the feeding arm to flip the feeding box to complete the feeding when the feeding arm is in the feeding position and the feeding box is vertically opposite to the opening of the pot.

[0013] Furthermore, the limiting component extends vertically and limits the screw sleeve by abutting against it. The first drive motor is a bidirectional motor. When the screw sleeve is limited, the first drive motor can reverse to cause the screw sleeve of the feeding arm to disengage from the limiting component and rotate. Thus, when the screw sleeve is limited by the limiting component, the screw sleeve disengages from the limiting component by changing the rotation direction of the first drive motor. The feeding arm rotates to adjust the circumferential position of the receiving box. For example, when receiving material, the position of the receiving box is adjusted by rotating the feeding arm to make it more accurately aligned with the outlet of the storage device, ensuring that all seasonings can fall smoothly into the receiving box. When receiving material, the position of the receiving box is adjusted to offset the outlet, ensuring that the feeding arm rises smoothly along the screw. When feeding material, the position of the receiving box is adjusted to make it more accurately aligned with the opening of the pot, ensuring that all seasonings can be smoothly added to the pot. Meanwhile, the first drive motor is a bidirectional motor, which enables the feeding arm to move back and forth between the receiving position and the feeding position. After feeding is completed, the feeding arm can automatically return to the receiving position by changing the rotation direction of the first drive motor, so as to facilitate the next round of feeding operation.

[0014] Furthermore, it also includes a base body, on which a limiting protrusion is provided on the outer circumferential surface of the threaded sleeve. The limiting component includes a first limiting rib protruding vertically on the base body. This first limiting rib is located on one side of the threaded sleeve and matches the height of the screw.

[0015] Furthermore, the lower end of the first limiting rib is recessed to form a limiting groove for the limiting protrusion to engage with the screw sleeve. When the feeding arm is in the receiving position, the limiting protrusion engages in the limiting groove, and the receiving box and the discharge port of the storage device are vertically aligned. After receiving the material, the first drive motor rotates forward to rotate the feeding arm until the limiting protrusion rotates out of the limiting groove. The first drive motor then rotates in reverse to make the limiting protrusion abut against the first limiting rib located above the limiting groove. The guiding cooperation between the first limiting rib and the limiting protrusion allows the feeding arm to rise smoothly along the screw (i.e., from the receiving position to the feeding position), avoiding spiral ascent that could cause the material in the receiving box to spill out. Furthermore, by setting a limiting groove at the lower end of the first limiting rib, the limiting protrusion is positioned using the limiting groove. On the one hand, the feeding arm can be stably positioned at the receiving position and the receiving box of the feeding arm is aligned vertically with the discharge port of the storage device, further ensuring smooth material receiving. On the other hand, the second drive motor drives the feeding arm to rotate, causing the limiting protrusion to rotate out of the limiting groove, while simultaneously causing the receiving box and the discharge port to be vertically misaligned. At this time, there are no obstructions above the feeding arm, allowing it to rise smoothly along the screw.

[0016] Furthermore, the limiting component also includes a second limiting rib protruding vertically on the base. This second limiting rib is located on the other side of the threaded sleeve and is opposite to the upper end of the first limiting rib. When the threaded sleeve moves to the upper end of the screw, the first drive motor rotates clockwise, causing the threaded sleeve to rotate. The limiting protrusion disengages from the first limiting rib and abuts against the second limiting rib, and the receiving box is vertically aligned with the opening of the pot. Thus, when the feeding arm rises to the feeding position, the limiting protrusion disengages from the first limiting protrusion and rotates by changing the rotation direction of the first drive motor. When the receiving box is adjusted to the required position (i.e., the receiving box is vertically aligned with the opening of the pot), the limiting protrusion abuts against the second limiting rib, and the threaded sleeve is radially limited again to ensure that the seasoning in the receiving box can be smoothly poured into the pot.

[0017] Furthermore, the limiting protrusion extends along the axial direction of the threaded sleeve. This allows the limiting protrusion to better abut against the limiting assembly, ensuring reliable radial limiting of the threaded sleeve.

[0018] Furthermore, the feeding arm is hollow, forming a cavity. The second drive structure includes a second drive motor disposed within this cavity. The output shaft of the second drive motor extends horizontally and passes through the cavity, connecting to the receiving box via a connector. Thus, when the feeding arm rises to the feeding position and the receiving box is vertically aligned with the opening of the pot, the second drive motor drives the receiving box to rotate, pouring the seasonings from the receiving box into the pot.

[0019] Furthermore, the storage device includes a storage box with an outlet at the bottom and a conveying box located below the outlet of the storage box. The bottom of the conveying box is open and a discharge sleeve is connected circumferentially. The discharge sleeve is inclined to one side from top to bottom, with its upper port being the inlet and its lower port forming the outlet. A conveying component is movably disposed within the conveying box to transport solid seasonings falling onto it to the inlet. Thus, the seasonings in the storage box fall through the outlet onto the conveying component in the conveying box, are transported by the conveying component to the inlet of the discharge sleeve, and finally output from the outlet under the guidance of the discharge sleeve.

[0020] Furthermore, the conveying component is a worm gear rotatably mounted in the conveying box, and the inner bottom surface of the conveying box is an inclined surface, with the discharge sleeve connected to the lowest point of the inner bottom surface. The system also includes a third drive structure for driving the worm gear to rotate, the third drive structure comprising a third drive motor. By driving the worm gear to rotate via the third drive motor, the seasoning that falls to the top of the worm gear is transported downwards to the discharge sleeve.

[0021] Furthermore, the storage box includes a first storage box and a second storage box arranged side by side. The conveying member extends along the arrangement direction of the two storage boxes and includes a first threaded segment corresponding to the first storage box and a second threaded segment corresponding to the second storage box along its own length. The thread directions of the first threaded segment and the second threaded segment are opposite, and a smooth intermediate section is provided between them. Each threaded segment abuts against the lower edge of the outlet of the corresponding storage box. The third drive motor is a bidirectional motor. Thus, when the third drive motor rotates forward, the first threaded segment of the worm rotates forward while the second threaded segment rotates in reverse. The first threaded segment squeezes the seasoning in the first storage box out of its outlet, while the second threaded segment cannot squeeze the seasoning in the second storage box out of its outlet, thereby realizing the discharge of the seasoning in the first storage box. Conversely, when the third drive motor reverses, the first threaded section of the worm rotates in reverse while the second threaded section rotates forward. The first threaded section cannot expel the seasonings from the first storage box at the outlet, while the second threaded section can expel the seasonings from the second storage box at its outlet, thus achieving the discharge of the seasonings from the second storage box. Therefore, this invention can achieve separate discharge of different seasonings by controlling the rotation direction of the third drive motor.

[0022] The technical solution adopted to further solve the second technical problem mentioned above is: a cooking machine, characterized in that it includes an automatic feeding mechanism for the cooking machine as described above.

[0023] Compared with the prior art, the advantages of this utility model are as follows: The feeding arm is threadedly connected to the screw rod via a screw sleeve. When the first drive motor rotates, the screw sleeve can rotate and move upward along the screw rod, thereby realizing the movement of the feeding arm between its receiving position and feeding position, and thus conveying the seasoning from a lower position to a higher position. Furthermore, the screw sleeve and screw rod are radially limited by the limiting component. When the feeding arm is in the receiving position, the receiving box and the outlet of the storage device are vertically aligned, ensuring that the seasoning falls smoothly into the receiving box. When the feeding arm is in the feeding position, the receiving box and the opening of the pot are vertically aligned, ensuring that the seasoning can be smoothly added to the pot. Moreover, when the feeding arm is in the feeding position, the second drive structure causes the receiving box to flip, pouring the seasoning into the pot, completing the feeding process.

[0024] As can be seen, this utility model realizes the automatic upward conveying of seasonings located below the opening of the pot and the automatic feeding of seasonings into the pot. Furthermore, the reliability of the automatic feeding and dispensing actions is ensured by accurately positioning the receiving box and the outlet, as well as accurately positioning the receiving box and the opening of the pot.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0038] like Figure 1 As shown, a cooking machine includes a worktable 1, a pot 2 placed on the worktable 1, and an automatic feeding mechanism 4 located on one side of the worktable 1. A range hood 3 is installed on the worktable 1. In this embodiment, the worktable 1 is the panel of a gas stove, the pot 2 is placed on the burner 11 of the gas stove, and the gas stove is installed on a cabinet 8.

[0039] like Figures 2-11As shown, the automatic feeding mechanism 4 includes a screw 41, a first drive structure 42, a feeding arm 43, a limiting component 44, and a second drive structure 45. The screw 41 extends vertically. The first drive structure 42 drives the screw 41 to rotate around its own axis and includes a first drive motor 421. The feeding arm 43 is horizontally positioned, with a receiving box 432 at one end and a threaded sleeve 431 at the other end. The threaded sleeve 431 is threaded onto the screw 41. When the threaded sleeve 431 is at the lower end of the screw 41, the feeding arm 43 is in the receiving position; when it is at the upper end of the screw 41, the feeding arm 43 is in the feeding position. The limiting component 44 radially limits the threaded sleeve 431 and the screw 41, so that when the feeding arm 43 is in the receiving position, the receiving box 432 and the outlet 532 of the storage device 5 are vertically aligned (e.g., when the feeding arm 43 is in the receiving position). Figure 2 As shown), when the feeding arm 43 is in the feeding position, the receiving box 432 is vertically aligned with the opening of the pot 2 (as shown). Figure 1 and Figure 6 (As shown). The second drive structure 45 is used to drive the feeding arm 43 to flip the feeding box 432 to complete the feeding when the feeding arm 43 is in the feeding position and the receiving box 432 is vertically opposite to the opening of the pot 2.

[0040] In this invention, the feeding arm 43 is threadedly connected to the screw 41 via a threaded sleeve 431. When the first drive motor 421 rotates, the threaded sleeve 431 rotates upwards along the screw 41, thereby moving the feeding arm 43 between its receiving position and the feeding position, thus conveying the seasoning from a lower position to a higher position. Furthermore, the limiting component 44 radially limits the threaded sleeve 431 and the screw 41. When the feeding arm 43 is in the receiving position, the receiving box 432 and the outlet 532 of the storage device 5 are vertically aligned, ensuring the seasoning falls smoothly into the receiving box 432. When the feeding arm 43 is in the feeding position, the receiving box 432 and the opening of the pot 2 are vertically aligned, ensuring the seasoning is smoothly added to the pot 2. Finally, when the feeding arm 43 is in the feeding position, the second drive structure 45 flips the receiving box 432, pouring the seasoning into the pot 2, completing the feeding process. As can be seen, this utility model realizes the automatic upward conveying of seasonings located below the pot 2 and the automatic feeding of seasonings into the pot 2. The reliability of the automatic receiving and feeding actions is ensured by the accurate positioning of the receiving box 432 and the discharge port 532 and the accurate positioning of the receiving box 432 and the opening of the pot 2.

[0041] Furthermore, the aforementioned limiting component 44 extends vertically and limits the aforementioned screw sleeve 431 by abutting against it. The aforementioned first drive motor 421 is a bidirectional motor. When the aforementioned screw sleeve 431 is limited, the first drive motor 421 can reverse to cause the screw sleeve 431 of the feeding arm 43 to disengage from the limiting component 44 and rotate. When the screw sleeve 431 is limited by the limiting component 44, the screw sleeve 431 is disengaged from the limiting component 44 by changing the rotation direction of the first drive motor 421. The feeding arm 43 rotates to adjust the circumferential position of the receiving box 432. For example, when receiving materials, the feeding arm 43 is rotated to adjust the position of the receiving box 432 so that it is more accurately aligned with the discharge port 532 of the storage device 5, so as to ensure that all seasonings can fall smoothly into the receiving box 432. When receiving materials, the position of the receiving box 432 is adjusted so that the receiving box 432 is offset from the discharge port 532, so as to ensure that the feeding arm 43 rises smoothly along the screw 41. When feeding materials, the position of the receiving box 432 is adjusted so that it is more accurately aligned with the opening of the pot 2, so as to ensure that all seasonings can be smoothly put into the pot 2. Meanwhile, the first drive motor 421 is a bidirectional motor, which enables the feeding arm 43 to move back and forth between the receiving position and the feeding position. After feeding is completed, the feeding arm 43 can automatically return to the receiving position by changing the rotation direction of the first drive motor 421, so as to facilitate the next round of feeding operation.

[0042] Furthermore, it also includes a seat 40, on which a limiting protrusion 4311 is provided on the outer peripheral surface of the aforementioned threaded sleeve 431, such as... Figure 2 As shown. The aforementioned limiting component 44 includes a first limiting rib 441 protruding vertically from the aforementioned seat 40. This first limiting rib 441 is located on one side of the aforementioned threaded sleeve 431 and matches the height of the screw 41. Furthermore, as... Figure 3As shown, the lower end of the first limiting rib 441 is recessed inward on the side that abuts against the threaded sleeve 431 to form a limiting groove 4411 into which the limiting protrusion 4311 is inserted. When the feeding arm 43 is in the receiving position, the limiting protrusion 4311 is inserted into the limiting groove 4411, and the receiving box 432 and the discharge port 532 of the storage device 5 are vertically opposite each other. After receiving the material, the first drive motor 421 rotates forward to make the feeding arm 43 rotate until the limiting protrusion 4311 is unscrewed out of the limiting groove 4411. The first drive motor 421 then rotates in reverse to make the limiting protrusion 4311 abut against the first limiting rib 441 located above the limiting groove 4411. The guiding cooperation between the first limiting rib 441 and the limiting protrusion 4311 allows the feeding arm 43 to rise smoothly in a straight line along the screw 41 (i.e., from the receiving position to the feeding position), avoiding the spillage of the material in the receiving box 432 due to spiral ascent. Furthermore, by providing a limiting groove 4411 at the lower end of the first limiting rib 441, the limiting protrusion 4311 is positioned. This not only stably positions the feeding arm 43 at the receiving position and aligns the receiving box 432 of the feeding arm 43 with the discharge port 532 of the storage device 5, further ensuring smooth material reception, but also allows the feeding arm 43 to rotate using the second drive motor 451, causing the limiting protrusion 4311 to rotate out of the limiting groove 4411. Simultaneously, the receiving box 432 and the discharge port 532 are vertically misaligned. At this point, there are no obstructions above the feeding arm 43, allowing it to rise smoothly along the screw 41.

[0043] Furthermore, such as Figure 7 As shown, the limiting component 44 also includes a second limiting rib 442 that protrudes vertically on the base 40. The second limiting rib 442 is located on the other side of the threaded sleeve 431 and is opposite to the upper end of the first limiting rib 441. When the threaded sleeve 431 moves to the upper end of the screw 41, the first drive motor 421 rotates forward to make the threaded sleeve 431 rotate. The limiting protrusion 4311 disengages from the first limiting rib 441 and abuts against the second limiting rib 442. The receiving box 432 is vertically opposite to the opening of the pot 2. When the feeding arm 43 rises to the feeding position, the rotation direction of the first drive motor 421 is changed, causing the limiting protrusion 4311 to disengage and rotate. When the receiving box 432 is adjusted to the desired position (i.e., the receiving box 432 is vertically aligned with the opening of the pot 2), the limiting protrusion 4311 abuts against the second limiting rib 442, and the screw sleeve 431 is radially limited again, ensuring that the seasoning in the receiving box 432 can be smoothly poured into the pot 2. Preferably, in the embodiment, as... Figure 10 and Figure 11As shown, the aforementioned limiting protrusion 4311 extends axially along the threaded sleeve 431, thereby enabling the limiting protrusion 4311 to better abut against the limiting component 44, ensuring the reliability of radial limiting of the threaded sleeve 431. In this embodiment, the aforementioned first limiting protrusion 4311 and second limiting protrusion 4311 are respectively protruding on two mutually perpendicular surfaces of the aforementioned seat 40. The aforementioned first driving structure 42 is also mounted on the aforementioned seat 40, and in addition to the first driving motor 421, it also includes a first gearbox 422, through which the driving force output by the first driving motor 421 is transmitted to the screw 41.

[0044] like Figure 10 and Figure 11 As shown, the feeding arm 43 is hollow, forming a cavity 430. The second drive structure 45 includes a second drive motor 451 disposed in the cavity 430. The output shaft of the second drive motor 451 extends horizontally and passes through the cavity 430, connecting to the receiving box 432 via a connector 6. Thus, when the feeding arm 43 rises to the feeding position and the receiving box 432 is vertically aligned with the opening of the pot 2, the second drive motor 451 drives the receiving box 432 to rotate, pouring the seasonings from the receiving box 432 into the pot 2. Specifically, in this embodiment, the connector 6 is a cylindrical block, and the outer surface of the receiving box 432 is recessed circumferentially with a connecting groove 4321. One side of the connector 6 has a mounting groove 61 for engaging the output shaft 4511 of the second drive motor 451, while the other side has a protruding connecting shaft 62 for engaging with the connecting groove 4321.

[0045] Furthermore, such as Figure 8 and Figure 9 As shown, the aforementioned storage device 5 is mounted on the aforementioned base 40 and includes a storage box with an outlet 510 at its bottom and a conveying box 52 located below the outlet 510 of the storage box. The bottom of the conveying box 52 has an output port 521, and a discharge sleeve 53 is circumferentially connected to the output port 521. The discharge sleeve 53 is inclined to one side from top to bottom, with its upper port forming the inlet 531 and its lower port forming the aforementioned discharge port 532. Furthermore, a conveying member 54 is movably disposed within the conveying box 52 to convey solid seasonings falling onto it to the inlet 531. Thus, the seasonings in the storage box fall through the outlet 510 onto the conveying member 54 in the conveying box 52, are conveyed by the conveying member 54 to the inlet 531 of the discharge sleeve 53, are then guided by the discharge sleeve 53 and output from the discharge port 532, finally falling into the receiving box 432 below the discharge sleeve 53. Preferably, the outlet 510 is located on one side of the storage box, and the inner bottom surface of the storage box is an inclined surface that slopes from top to bottom toward the outlet 510.

[0046] Specifically, such as Figure 8As shown, the conveying component 54 is a worm gear rotatably mounted in the conveying box 52. The inner bottom surface of the conveying box 52 is inclined, and the discharge sleeve 53 is connected to the lowest point of this inner bottom surface. The conveying box 52 also includes a third drive structure 7 for driving the worm gear to rotate, which includes a third drive motor 71. By driving the worm gear to rotate via the third drive motor 71, the seasoning that falls to the top of the worm gear is transported downwards to the discharge sleeve 53. Furthermore, the aforementioned storage boxes include a first storage box 511 and a second storage box 512 arranged side by side. The aforementioned conveying member 54 extends along the arrangement direction of the two storage boxes and includes a first threaded section 541 corresponding to the first storage box 511 and a second threaded section 542 corresponding to the second storage box 512 along its own length direction. The thread directions of the first threaded section 541 and the second threaded section 542 are opposite, and a smooth outer peripheral section 543 is provided between them. Each threaded section abuts against the lower edge of the outlet 510 of the corresponding storage box. The aforementioned third drive motor 71 is a bidirectional motor. Thus, when the third drive motor 71 rotates forward, the first threaded section 541 of the worm rotates forward while the second threaded section 542 rotates in reverse. The first threaded section 541 squeezes the seasoning in the first storage box 511 out through its opening, while the second threaded section 542 cannot squeeze the seasoning in the second storage box 512 out through its outlet 510, thereby realizing the discharge of the seasoning in the first storage box 511. Conversely, when the third drive motor 71 reverses, the first threaded section 541 of the worm rotates in reverse while the second threaded section 542 rotates forward. The first threaded section 541 cannot expel the seasonings from the first storage box 511 through the outlet 510, while the second threaded section 542 can expel the seasonings from the second storage box 512 through its outlet 510, thus achieving the discharge of the seasonings from the second storage box 512. Therefore, this invention can achieve separate discharge of different seasonings by controlling the rotation direction of the third drive motor 71.

[0047] In this embodiment, specifically, as follows: Figure 8 As shown, the third drive structure 7 is disposed on one side of the material conveying box 52, and in addition to the third drive motor 71, it also includes a second gearbox 72. The driving force output by the third drive motor 71 is transmitted to the worm gear through the second gearbox 72.
