[0002] With the development of science and technology and the improvement of living standards, there are more and more automated cooking equipment and they are becoming more and more intelligent. An automatic cooking machine is a machine that simulates manual cooking. When cooking, you only need to put in all the pre-prepared main ingredients, side ingredients, and condiments at once. After setting the program, it can automatically heat the oil, stir-fry, and control the heat. It has the advantages of being able to cook automatically without manual supervision and experience.

[0003] In order to simulate the process of manual cooking, the existing cooking machines have a method of setting a material-stirring member in the kettle body that rotates with the kettle body, and stirring or shifting the material through the rotation of the kettle body. However, this structure cannot achieve a more uniform process of frying the material. Another method is to set a stirring blade in the kettle body and use a driving mechanism to drive the stirring blade to stir and shift the material. However, these two methods of simulating manual cooking are still quite different from manual cooking, and the cooking quality is still lacking compared to manual cooking. Summary of the invention

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below. A person skilled in the art will be able to implement the embodiments using relevant techniques in the art according to the following description and will be able to better understand the innovations and benefits of the present invention.

[0026] The scraper driving mechanism of the embodiment of the present application is used to drive the scraper to move in the kettle of the automatic cooking machine, so as to achieve stirring, stir-frying, etc. of the materials (raw materials and auxiliary materials for cooking, etc.) in the kettle.

[0027] like Figure 1 As shown, Figure 1 This is an overall structural diagram of a scraper driving mechanism. The present invention proposes a scraper driving mechanism, comprising: a clutch 4 and a driving portion 3, wherein the clutch 4 is provided with an output portion 46 for connecting to the scraper 2; and an input portion 43 connected to the driving portion 3 and capable of being separated from or combined with the output portion 46.

[0028] refer to Figure 3 and Figure 4As shown, the driving part 3 is driven by a driving member 5, so that the driving part 3 can swing around the output shaft of the driving member 5, thereby driving the scraper 2 connected to the clutch 4 to move. Specifically, the driving part 3 drives the scraper 2 connected to the clutch 4 to enter from the opening 10 of the kettle body 1, so that the scraper 2 moves along the inner wall of the kettle body 1 to the bottom of the kettle body, and then drives the scraper 2 from the bottom of the kettle body 1 along the inner wall of the kettle body to the opening of the kettle body 1, and so on. The purpose of stir-frying is achieved by alternating reciprocating motion. When the driving part 3 drives the scraper 2 to enter the kettle body 1, the clutch 4 can be used to disconnect the circumferential limit of the scraper 2 by the driving part 3, so that the scraper 2 can rotate with the kettle body 1.

[0029] See also Figure 1 As an embodiment, the input part of the clutch 4 is a sleeve 43, and the clutch 4 specifically includes: a sleeve 43, a reset member 42, and an output part 46. One end of the reset member 42 is limited in the sleeve 43, a first coupling part 431 is provided in the sleeve 43, and a second coupling part 48 is provided on the output part 46. The circumferential limit between the sleeve 43 and the output part 46 is achieved by the engagement of the first coupling part 431 and the second coupling part 48. The other end of the reset member 42 is connected to the output part 46 and the first coupling part 431 is engaged with the second coupling part 48. When the output part 46 is acted upon by the scraper 2, the reset member 42 is driven by the force to cause the second coupling part 48 to disengage from the first coupling part 431, so that the circumferential limit of the sleeve 43 on the output part 46 disappears. At this time, driven by the kettle body 1, the scraper 2 can rotate with the kettle body 1.

[0030] In this embodiment, the engagement and disengagement of the clutch 4, that is, the axial engagement or disengagement of the output portion 46 and the sleeve 43, is achieved based on the force exerted on the output shaft by the scraper 2, and there is no need for a motor to drive the clutch to achieve the clutch process, which is more suitable for environments with a lot of water vapor and oil smoke such as cooking machines, and reduces the cost of the scraper drive mechanism. If a motor is used to drive the clutch to achieve the clutch process, the protection level required for the motor is very high, which is not conducive to the cleaning process.

[0031] In this embodiment, the reset member 42 is an elastic member, and a spring is used as an example in this embodiment. Of course, a corrugated rubber tube, an elastic rubber sleeve or other elastic members may also be used instead. The elastic member meshes the first joint portion 431 and the second joint portion 48 under the action of elastic force, and when the output portion 46 is subjected to the axial force of the scraper 2, the elastic member is squeezed to separate the first joint portion 431 from the second joint portion 48.

[0032] As an implementable embodiment, the output portion 46 is an output shaft structure, which is sleeved inside the sleeve 43 , and the output end extends out to be connected with the scraper 2 .

[0033] As an implementation method, the meshing mode between the first joint part 431 and the second joint part 48 is tooth meshing, and of course, friction meshing can also be used. The tooth meshing mode can be more stable, especially in the oil smoke environment, the reliability of the tooth meshing is better.

[0034] In this embodiment, the first coupling portion 431 and the second coupling portion 48 are specifically engaged by straight teeth. Figure 1 As shown, the second coupling portion 48 of the output portion 46 is a straight tooth disposed on the circumferential side wall of the shaft, as shown in FIG. Figure 2 As shown, the inner wall of the sleeve 43 is provided with an annular flange to divide the sleeve 43 into a lower cavity 432 and an upper cavity 433. A guide structure is provided on the end surface of the annular flange to set corresponding straight teeth to form the first joint portion 431. The upper cavity 433 can provide a setting space for the elastic member 42, and the lower cavity 432 is used to realize the axial limit structure arrangement of the output portion 46. The structure of the straight tooth meshing is relatively simple and easy to process.

[0035] Optionally, a guide structure may be provided on the end face of the annular flange along the contour of the first combining part, and the guide structure may guide the second combining part when it begins to combine with the first combining part, so that the second combining part can be smoothly combined with the first combining part; the guide structure may be a chamfered structure opened on the end face contour of the first combining part.

[0036] As a setting method of the second coupling portion 48, a shoulder can be set on the output portion 46, and the second coupling portion 48 is set on the shoulder. By setting the second coupling portion 48 on the shoulder of the output portion 46, the shoulder can be used to achieve axial limitation of the output portion 46.

[0037] As an alternative embodiment, the first coupling portion 431 and the second coupling portion 48 may also be engaged by bevel gears or face gears. By using bevel gears or face gears, the bevel gear structure or face gear structure may be used to limit the axial position of the output shaft, further simplifying the internal structure of the sleeve. However, the difficulty of processing is also increased accordingly.

[0038] Taking the embodiment in which the straight teeth are used as the first coupling part 431 and the second coupling part 48 as an example, at least one limiting sleeve 44 is provided in the lower cavity 432 to limit the axial position of the output part 46, thereby ensuring that the second coupling part 48 can be effectively coupled with the first coupling part 431. In this embodiment, there are two limiting sleeves 44, and of course, there can also be one, three, four, etc., which are provided according to the axial movement stroke of the output part 46.

[0039] The limiting sleeve 44 is fixed to the first end of the sleeve 43, that is, one end of the lower cavity 432, through a gasket 45. The gasket 45 can prevent the limiting sleeve 44 from slipping out of the lower cavity 432.

[0040] Furthermore, the upper end of the reset member 42 is restricted to the second end of the sleeve 43, i.e., one end of the upper cavity 433, by the end cover 41, and the lower end of the reset member 42 abuts against the upper end of the output portion 46 (the end where the second coupling portion 48 is located). The end cover 41 can ensure that the reset member 42 will not fall out of the sleeve 43, and can ensure that the reset member 42 can abut against the output portion 46.

[0041] Continue to see Figure 1 The first end of the driving part 3 is fixedly connected to the first end of the sleeve 43 by a screw (or a limit column, welding, etc.), and the screw can fasten the driving part 3 and the gasket 45; the second end of the driving part 3 can be connected to a driving device (such as a motor). The first end of the scraper 2 is fixedly connected to the lower end of the output part 46 by a fastener 47, and the fastener 47 can be a bolt, a screw, etc.

[0042] Based on the above driving mechanism, the present invention also provides a specific implementation of a scraper assembly, such as Figure 3 As shown, Figure 3 The overall structure diagram of the scraper assembly includes a scraper drive mechanism of any of the above schemes, and a scraper 2 connected to the scraper drive mechanism. One end of the scraper 2 is fixedly connected to the lower end of the output portion 46; the scraper 2 is provided with an adapter 6 for limiting its axial movement relative to the output portion 46. When the scraper 2 is disconnected from the clutch 4, the adapter 6 just cooperates with the end surface of the kettle 1 to drive the scraper 2 to rotate synchronously with the kettle 1. By arranging the scraper drive mechanism on the scraper assembly, the scraper assembly can achieve uniform frying of the dishes in the kettle 1, avoiding uneven frying of the dishes in the kettle 1.

[0043] As another embodiment of the present invention, the present invention also provides a cooking mechanism, such as Figure 4 As shown, the cooking mechanism comprises the scraper driving mechanism, the scraper 2 connected to the scraper driving mechanism, and the kettle body 1. The driving part 3 of the scraper driving mechanism drives the scraper 2 to reciprocate along the inner wall of the kettle body 1 between the opening of the kettle body 1 and the bottom wall of the kettle body 1. By arranging the scraper driving mechanism on the cooking mechanism, the cooking mechanism can realize uniform frying of the dishes in the kettle body 1, avoiding uneven frying of the dishes in the kettle body 1.

[0044] like Figure 4As shown, the scraper driving mechanism also includes a driving member 5, which is arranged outside the kettle body. The driving member 5 is arranged at the side of the waist of the kettle body, and one end of the driving part is connected to the output shaft of the driving member 5. The driving member 5 drives the driving part to swing around the output shaft to drive the scraper 2 in the kettle body along the inner wall of the kettle body and reciprocate between the kettle body opening and the bottom wall of the kettle body.

[0045] Furthermore, the end face of the opening of the kettle body 1 is also provided with a limiting structure corresponding to the adapter 6 (which may be a groove or a boss adapted to the shape of the adapter 6). When the scraper 2 is driven by the driving part 3 to enter the kettle body 1 to a certain depth, the adapter 6 presses against the end face of the opening 10 of the kettle body 1, and the driving part 3 continues to rotate. Restricted by the end face of the opening 10 of the kettle body 1, the scraper 2 pushes the output part 46 along the sleeve 43 to move toward the end cover 41, so that the first joint part 431 and the second joint part 48 are disengaged. At this time, the output part 46 is no longer limited in the circumferential direction. At the same time, the adapter 6 can adaptively cooperate with the limiting structure. Restricted by the limiting structure, the scraper 2 can rotate synchronously with the kettle body 1. By providing the adapter 6, the axial pressure of the scraper 2 is provided so that the output part 46 and the driving part are disengaged from the circumferential limit. At the same time, the scraper 2 can rotate with the kettle body 1, and the process of stir-frying and picking materials by the scraper 2 is realized.

[0046] Of course, since the output portion 46 is fixedly connected to the scraper 2 , the adapter 6 can also be disposed on the output portion 46 .

[0047] As described above, the scraper 2 has two motion states: A, swinging around the output shaft of the driving device 5 with the driving part 3; B, rotating synchronously with the kettle body 1; the switching between the two motion states A and B is realized by the clutch 4. The driving part 3 is fixedly connected to the sleeve 43 of the clutch 4, and the output part 46 of the clutch 4 is fixedly connected to the scraper 2. The output part 46 can move along the axis of the sleeve 43 in the sleeve 43 under the axial pressure of the scraper 2. The upper end of the output part 46 is provided with a second coupling part 48, the sleeve 43 is provided with a first coupling part 431, and the upper cavity 433 of the sleeve 43 is provided with a reset member 42. The reset member 42 keeps the first coupling part 431 and the second coupling part 48 in a coupling state in the absence of external force. If the scraper 2 is in the A motion state, the clutch 4 is in the engaged state, and the scraper 2 is constrained by the clutch 4, resulting in the kettle body 1 being unable to drive the scraper 2 to rotate; when the scraper 2 moves to a certain depth in the kettle body 1 along with the driving part 3, the scraper 2 is subjected to the reaction force of the end face of the opening 10 of the kettle body 1, thereby beginning to overcome the elastic force of the reset member 42 to make the second coupling part 48 of the output part 46 gradually separate from the first coupling part 431. When the second coupling part 48 is completely separated from the first coupling part 431, the output part 46 is freed from the circumferential limit of the sleeve 43, thereby enabling the scraper 2 to switch to the B motion state.

[0048] In the present invention, the clutch 4 does not need to be driven by a motor, has a simple structure, and is more suitable for environments with a lot of water vapor and oil smoke such as cooking machines, reducing the cost of the scraper drive mechanism. If a motor is used to drive the clutch to achieve the clutch process, the protection level required by the motor is very high, which is not conducive to the cleaning process.

[0049] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific embodiments of the present invention are limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
