[0002] As people's living standards improve, cooking machines are used more and more widely. Existing cooking machines are equipped with stirring blades in the pot to stir the food. There is a certain gap between the stirring blades and the pot wall, and the stirring blades are always in a fixed vertical height during the rotating stirring process. When there are many ingredients to be stirred, it is easy to cause the food to get stuck between the stirring blades and the pot wall, affecting the cooking effect.

[0003] Another problem arises after cooking is finished. The bottom of the stirring blade is difficult to clean due to the small space. If it is not cleaned properly, it will cause hygiene problems. Summary of the Invention

[0007] Preferably, the first special-shaped structure is a protrusion arranged on the inner wall of the positioning sleeve and a closed-loop slide on the outer wall of the rotating shaft opposite to the protrusion.

DETAILED DESCRIPTION

[0024] In the wok device of the present invention, a fork for stirring the ingredients in the wok 10 is arranged to be capable of rotating relative to the wok 10 and simultaneously reciprocating up and down along the fork's rotating shaft 33. That is, the fork rotates in a horizontal plane and moves up and down at the same time. During the process of frying ingredients, when the fork pushes a large amount of ingredients, the fork intermittently changes the gap between the fork and the wall of the wok 10 by moving up and down, which can effectively prevent the ingredients from getting stuck between the fork and the wok 10. At the same time, the method of pressing and frying the ingredients can be simulated to compact the ingredients, make the ingredients more flavorful, and improve the heating uniformity of the ingredients.

[0025] Specifically, such as Figure 1-2 As shown, the wok device includes a wok 10, a wok shaft 11 fixed to the bottom of the wok 10, a fork arranged in the wok 10 for stir-frying ingredients, a wok shaft motor 12 for driving the wok 10 to rotate, a fork motor 31 for driving the fork to rotate, and a shell 20 wrapped around the outer periphery of the wok 10 and used to bear the weight of the wok 10 and other components.

[0026] The frying pan 10 is preferably an iron or metal composite pot body with a cylindrical upper portion and a hemispherical lower portion, and the bottom of the frying pan 10 is a circular plane.

[0027] The wok shaft 11 is a hollow shaft with a hollow passage, the upper end of which is fixedly connected to the bottom of the wok 10 and is coaxially arranged with the central through hole in the bottom of the wok 10 .

[0028] The shift fork includes a shift fork leaf 32 and a rotating shaft 33 that drives the shift fork leaf 32 to rotate. The rotating shaft 33 of the shift fork is coaxially arranged with the pot shaft 11.

[0029] The shift fork leaf 32 is arranged in the frying pan 10, one end of the rotating shaft 33 is fixed to the shift fork leaf 32, and the other end preferably passes through the central through hole and the pot shaft 11 in sequence and extends downward to connect with the output end of the shift fork motor.

[0030] In order to make the shaft 33 realize both rotational motion and up and down motion, Figure 4 As shown, a spline sleeve 7 is sleeved on the lower part of the rotating shaft 33, and the lower end of the spline sleeve 7 is fixedly connected to the output end of the fork motor 31. The rotating shaft 33 opposite to the spline sleeve 7 is a spline shaft 311, and the spline shaft 311 is meshed with the spline sleeve 7, that is, the two are connected in the circumferential direction. After the fork motor 31 is turned on, its output end drives the spline sleeve 7 and the rotating shaft 33 to rotate synchronously, and the rotating shaft 33 can be displaced up and down along its axial direction in the spline sleeve 7 under the action of external force. The length of the sleeved part of the spline sleeve 7 and the rotating shaft 33 is greater than the maximum distance that the rotating shaft 33 can be displaced up and down.

[0031] In order to prevent the rotating shaft 33 from generating eccentric motion during the rotation process, smooth sleeves 34 are provided at the upper and lower ends of the rotating shaft 33 and are coaxially arranged with the rotating shaft 33 to axially position the rotating shaft 33.

[0032] A sealing connection structure 6 is provided at the central through hole for axially positioning the rotating shaft 33 and preventing the soup in the frying pan 10 from flowing out.

[0033] The shell 20 has an upper open accommodating cavity, and the frying pan 10 is installed in the accommodating cavity. The pot shaft 11 and the fork shaft pass through the bottom of the shell 20 and are placed below the shell 20. The pot shaft motor 12 and the fork motor are both fixed on the shell 20.

[0034] The pot shaft motor 12 can be a direct drive motor, a worm gear reduction motor or a spur gear multi-stage reduction motor. Different types of pot shaft motors 12 are connected to the pot shaft 11 in different ways. Conventional connection methods in the mechanical field can be used.

[0035] The key improvements of this utility model are: Figure 2 and Figure 3 As shown, a positioning sleeve 5 is sleeved on the rotating shaft 33, and the positioning sleeve 5 is fixedly connected to the pot shaft 11, as shown in FIG. Figure 5 As shown, the positioning sleeve 5 can also be fixedly connected to the shell 20 of the frying pan device, and a first special-shaped structure is provided between the positioning sleeve 5 and the rotating shaft 33, which can make the rotating shaft 33 move up and down when the rotating shaft 33 and the positioning sleeve 5 rotate relative to each other.

[0036] The first special-shaped structure mainly includes the following structures:

[0037] 1) If Figure 3 and Figure 6As shown, the first special-shaped structure comprises a protrusion 41 provided on the outer peripheral wall of the rotating shaft 33 and a closed-loop slideway 42 on the inner wall of the positioning sleeve 5 opposite to the protrusion 41. The track formed by the slideway 42 on the inner wall of the positioning sleeve 5 is a curved graph that moves up and down along its axis. That is, when the positioning sleeve is unfolded into a plane, the slideway 42 forms an undulating curved graph. The protrusion 41 is embedded in the slideway 42.

[0038] The unfolded plane shape of the slide 42 can be a triangular wave or a sawtooth wave; preferably, the protrusion 41 is a cylindrical structure, and the unfolded plane shape of the slide 42 is a sine waveform; the height and frequency of the fork leaf moving up and down in the wok 10 are determined by the shape of the slide 42, such as: within the same circle, the greater the difference between the peak value and the trough value of the sine wave, the higher the height of the fork leaf 32 moving up and down, the shorter the period of the sine wave, and the higher the frequency of the fork leaf 32 moving up and down.

[0039] The specific installation of the structure: Figure 7 As shown, an insertion track 51 extending vertically upward is provided within the positioning sleeve 5 at a position corresponding to the highest point of the slideway 42. When the positioning sleeve 5 is mounted on the rotating shaft 33, the protrusion 41 is inserted along the insertion track 51 and ultimately placed within the slideway 42. Once the protrusion 41 is in place, a retaining spring 52, located at the highest point of the slideway 42 and embedded in the inner wall of the positioning sleeve 5, confines the protrusion 41 within the slideway 42, preventing the protrusion 41 from sliding out of the insertion track 51 during movement. Finally, the positioning sleeve 5 is secured to the pot shaft 11 or the housing 20 using screws or other mounting brackets.

[0040] like Figure 8 As shown, the structure in which the protrusion 41 is installed in the slide 42 can also be that the protrusion 41 is set as a component that is elastically retractable in the horizontal direction. When the positioning sleeve 5 is put on the rotating shaft 33, the protrusion 41 is horizontally compressed inward and the spring is clamped into the positioning sleeve 5 and is in a compressed state under the action of the inner wall of the positioning sleeve 5 until the protrusion 41 slides to the position of the slide 42, and the protrusion 41 is ejected under the action of the spring to be embedded in the slide 42.

[0041] 2) This structure is based on the same principle as the first structure, with the difference being that the positions of the protrusion 41 and the slide 42 are swapped, i.e., the first special-shaped structure includes a protrusion 41 provided on the inner peripheral wall of the positioning sleeve 5 and a closed-loop slide 42 (not shown in the figure) on the outer peripheral wall of the rotating shaft 33 opposite to the protrusion 41. The trajectory formed by the slide 42 on the outer peripheral wall is a curved figure that moves up and down along its axial direction, and the protrusion 41 is embedded in the slide 42.

[0042] The specific installation of this structure is as follows: a mounting hole for the protrusion 41 is provided on the positioning sleeve 5. The positioning sleeve 5 is first sleeved on the rotating shaft 33, and then the protrusion 41 is inserted from the mounting hole of the protrusion 41 and the inner end of the protrusion 41 is placed in the slide 42. The protrusion 41 and the mounting hole of the protrusion 41 can be clamped or screwed together.

[0043] The utility model respectively arranges a slide 42 and a protrusion 41 on two components that rotate relative to each other, so that the protrusion 41 is embedded in the slide 42. During the relative rotation, the protrusion 41 is pushed to slide in the upper and lower concave and convex tortuous slide 42, thereby realizing the up and down movement of one of the components. The utility model utilizes an ingenious structure to simply achieve a reliable functional design.

[0044] The number of the protrusion 41 in the "1)" or "2)" structure is at least one. When the number of the protrusion 41 is one (an axial positioning device is provided between the rotating shaft 33 and the positioning sleeve 5 to ensure that the rotating shaft 33 and the positioning sleeve 5 always remain coaxial), the slide 42 can be an irregular closed-loop curve, that is, the rotating shaft 33 carries the fork leaf 32 and the wok 10 to rotate relative to each other for one circle, and the height and frequency of its up and down movement are various. The irregular-shaped slide 42 can realize diverse stir-frying during the stirring process of the fork leaf 32.

[0045] When there are two protrusions 41, the two protrusions 41 are located in the same vertical plane passing through the axis of the rotating shaft 33. In this structure, the distribution of the two protrusions 41 preferably has the following two situations:

[0046] A. Figure 3 As shown, the two protrusions 41 are in the same horizontal plane and are symmetrically arranged about the axis of the rotating shaft 33, and the two protrusions 41 are embedded in the same slideway 42. When the rotating shaft 33 moves up and down, the two protrusions 41 move along the same trajectory in the slideway 42.

[0047] By arranging two symmetrical protrusions 41 in the slideway 42 to support the rotating shaft 33, the force is more balanced and the sliding process is smoother.

[0048] B. Figure 9 As shown, the two protrusions 41 are offset up and down and are set relative to the axis of the rotating shaft 33. Under this structure, there are two slideways 42, which are also offset up and down. During the up and down movement of the rotating shaft 33 in the positioning sleeve 5, the two protrusions 41 move along the same trajectory in the corresponding slideway 42 and there is no overlapping point between the two trajectories.

[0049] The support of the double protrusion 41 is achieved by two slideways 42 , which can ensure the sliding stability while setting a variety of moving heights and frequencies within one rotation cycle.

[0050] When there are multiple protrusions 41, the trajectory of the slideway 42 is determined by the specific distribution positions of the protrusions 41. Preferably, the multiple protrusions 41 are distributed at equal intervals in the circumferential direction.

[0051] When the positioning sleeve 5 is fixed on the pot shaft 11, the positioning sleeve 5 can be embedded in the hollow channel of the pot shaft 11 in an embedded manner; it can also be fixed to the pot shaft 11 by partially sleeved on the lower end of the pot shaft 11; it can also be directly fixed on the pot shaft 11 by means of an auxiliary frame or the like.

[0052] After being installed in the above three ways, the positioning sleeve 5, the rotating shaft 33 and the pot shaft 11 are all coaxial.

[0053] Based on the above structure, the working modes of the wok 10 and the fork are as follows:

[0054] 1) The fork motor 31 does not work (i.e., the rotating shaft 33 does not rotate), and the pot shaft motor 12 drives the pot shaft 11 to rotate synchronously with the frying pan 10 and the positioning sleeve 5. The protrusion 41 on the rotating shaft 33 passively slides in the slideway 42 during the rotation of the positioning sleeve 5, thereby causing the rotating shaft 33 to carry the fork leaf 32 to move up and down.

[0055] In this case, only one component needs to be driven to rotate in order to simultaneously realize the relative rotation and up and down movement of the two components.

[0056] 2) The fork motor 31 drives the rotating shaft 33 and the fork leaf 32 to rotate, and at the same time, the pot shaft motor 12 drives the pot shaft 11 to rotate at different speeds (in the same direction or in the opposite direction), that is, relative rotation occurs between the rotating shaft 33 and the positioning sleeve 5, so that the protrusion 41 on the rotating shaft 33 can slide in the slideway 42 of the positioning sleeve 5, and then the rotating shaft 33 and the fork leaf 32 can produce up and down movement while rotating relative to the wok 10.

[0057] 3) The fork motor 31 drives the rotating shaft 33 to rotate with the fork leaf 32, and at the same time, the pot shaft motor 12 drives the pot shaft 11 to rotate in the opposite direction at the same speed, that is, relative rotation occurs between the rotating shaft 33 and the positioning sleeve 5, so that the protrusion 41 on the rotating shaft 33 can slide in the slideway 42 of the positioning sleeve 5, and then the rotating shaft 33 and the fork leaf 32 can generate up and down movement while rotating relative to the frying pan 10.

[0058] 4) The pot shaft motor 12 does not work, and the fork motor 31 drives the rotating shaft 33 to rotate with the fork leaf 32. The protrusion 41 on the rotating shaft 33 slides in the slideway 42 of the positioning sleeve 5, thereby causing the rotating shaft 33 to move up and down with the fork leaf 32.

[0059] When the positioning sleeve 5 is fixed on the shell 20, the rotation of the wok 10 does not affect the rotation and up and down movement of the rotating shaft 33. Under this structure, as long as the wok 10 and the rotating shaft 33 do not rotate at the same speed and in the same direction, the relative rotation and up and down displacement of the wok 10 and the fork leaf 32 can be achieved.

[0060] Furthermore, in order to enable the frying pan 10 to move up and down, a pot shaft 11 positioning sleeve is provided on the pot shaft 11, and the pot shaft 11 positioning sleeve is fixed on the shell 20. A second special-shaped structure that enables the frying pan 10 to move up and down is provided between the outer peripheral wall of the pot shaft 11 and the inner wall of the pot shaft 11 positioning sleeve.

[0061] The second special-shaped structure is identical to the first special-shaped structure and has the same working principle, so it will not be described again.

[0062] The up and down movement of the wok 10 can achieve an effect similar to that of a chef flipping the wok during cooking.
