Description

Technical Field

[0001] This invention relates to the field of cooking utensils, and more particularly to a wok device. Background Technology

[0002] As people's living standards improve, cooking machines are being used more and more widely. Existing cooking machines have stirring blades inside the pot to stir the food. There is a certain gap between the stirring blades and the pot wall, and the stirring blades remain in a fixed vertical position during the rotation process. When there is a lot of food to stir, it is easy for food to get stuck between the stirring blades and the pot wall, which affects the cooking effect.

[0003] Another problem arises after cooking: the bottom of the stirring blade is difficult to clean due to the small space, and incomplete cleaning can cause hygiene issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wok device that can move in three-dimensional space and effectively prevent food from getting stuck.

[0005] To solve the above-mentioned technical problems, the present invention provides a wok device, including a wok, a wok shaft, and a fork disposed inside the wok for stir-frying food. The rotating shaft of the fork is coaxially disposed with the wok shaft. A positioning sleeve is sleeved on the rotating shaft. The positioning sleeve is fixedly connected to the housing of the wok device or the wok shaft. A first irregular structure is provided between the positioning sleeve and the rotating shaft, which allows the rotating shaft to move up and down when the rotating shaft rotates relative to the positioning sleeve.

[0006] Preferably, the first irregular structure is a protrusion on the outer peripheral wall of the rotating shaft and a closed-loop slide on the inner wall of the positioning sleeve opposite to the protrusion. The trajectory formed by the slide on the inner wall of the positioning sleeve is a curved pattern that moves up and down along its axial direction, and the protrusion is embedded in the slide.

[0007] Preferably, the first irregular structure is a protrusion on the inner peripheral wall of the positioning bushing and a closed-loop slide on the outer peripheral wall of the rotating shaft opposite to the position of the protrusion. The trajectory formed by the slide on the outer peripheral wall is a curved pattern that moves up and down along its axial direction, and the protrusion is embedded in the slide.

[0008] Preferably, there are two protrusions, and they are located in the same vertical plane passing through the axis of rotation.

[0009] Preferably, the two protrusions are arranged symmetrically on the same horizontal plane and around the axis of rotation, and the two protrusions move along the same trajectory in the slide during the up-and-down movement of the axis of rotation.

[0010] Preferably, the two protrusions are staggered vertically and arranged relative to each other with respect to the axis of rotation. There are two slides arranged vertically. During the vertical movement of the rotating shaft, the two protrusions move along the same trajectory in the corresponding slides and the two trajectories do not overlap.

[0011] Preferably, a splined sleeve is fitted onto the lower part of the rotating shaft, the splined sleeve is connected to the output end of the shift fork motor, the rotating shaft opposite to the splined sleeve is a splined shaft, and smooth sleeves for axial positioning of the rotating shaft are also provided at the upper and lower ends of the rotating shaft.

[0012] Preferably, a pot shaft positioning sleeve is fitted onto the pot shaft, and the pot shaft positioning sleeve is fixed to the housing. A second irregular structure is provided between the outer peripheral wall of the pot shaft and the inner wall of the pot shaft positioning sleeve, which allows the wok and the fork to move up and down.

[0013] The wok device of the present invention uses a positioning bushing fitted around the rotating shaft that drives the fork to rotate inside the wok for stirring the ingredients. A first irregular structure is set between the rotating shaft and the bushing. This allows the fork to rotate relative to the wok while simultaneously moving up and down along the rotation axis of the fork. That is, the fork can rotate in the horizontal plane and move up and down at the same time. During the cooking process, when the fork pushes a lot of ingredients, the fork intermittently changes the gap between the fork and the wok wall by moving up and down, which can effectively prevent the food from getting stuck between the fork and the wok. At the same time, it can simulate the chef's pressing and frying technique to compact the ingredients, making the ingredients more flavorful and improving the evenness of heating.

Detailed Implementation

[0024] The wok device of the present invention configures the stirring fork inside the wok 10 to rotate relative to the wok 10 and reciprocate up and down along the rotation axis 33 of the fork. That is, the fork can rotate in the horizontal plane and move up and down at the same time. During the cooking process, when the fork pushes a lot of food, 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 food from getting stuck between the fork and the wok 10. At the same time, it can simulate the chef's pressing and frying technique to compact the food, making the food more flavorful and improving the heat uniformity of the food.

[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 for stir-frying ingredients inside the wok 10, a wok shaft motor 12 for driving the wok 10 to rotate, a fork motor 31 for driving the fork to rotate, and a housing 20 that surrounds the wok 10 and supports the weight of the wok 10 and other components.

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

[0027] The pot shaft 11 is a hollow shaft with a hollow channel. Its upper end is fixed to the bottom of the wok 10 and is coaxially arranged with the central through hole at the bottom of the wok 10.

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

[0029] The fork blade 32 is disposed inside the wok 10. One end of the rotating shaft 33 is fixed to the fork blade 32, and the other end preferably extends downward through the central through hole and the wok shaft 11 and is connected to the output end of the fork motor.

[0030] To enable the rotating shaft 33 to achieve both rotational and vertical movement, such as Figure 4As shown, a splined sleeve 7 is fitted onto the lower part of the rotating shaft 33. The lower end of the splined sleeve 7 is fixedly connected to the output end of the shift fork motor 31. The rotating shaft 33 opposite to the splined sleeve 7 is a splined shaft 311. The splined shaft 311 meshes with the splined sleeve 7, thus achieving a circumferential limiting connection between the two. After the shift fork motor 31 is turned on, its output end drives the splined sleeve 7 to rotate synchronously with the rotating shaft 33. Under the action of external force, the rotating shaft 33 can move up and down along its axis within the splined sleeve 7. The length of the part of the splined sleeve 7 that is fitted with the rotating shaft 33 is greater than the maximum distance that the rotating shaft 33 can move up and down.

[0031] To prevent the rotating shaft 33 from eccentrically moving during rotation, smooth sleeves 34 are provided at both the upper and lower ends of the rotating shaft 33, which are coaxially arranged with the rotating shaft 33 and axially position the rotating shaft 33.

[0032] A sealing connection structure 6 is also provided at the central through hole to axially position the rotating shaft 33 and prevent soup or other liquids from flowing out of the wok 10.

[0033] The housing 20 has an open upper cavity, in which the wok 10 is installed. The wok shaft 11 and the fork shaft pass through the bottom of the housing 20 and are positioned below the housing 20. The wok shaft motor 12 and the fork motor are both fixed to the housing 20.

[0034] The boiler shaft motor 12 can be a direct-drive motor, a worm gear reducer motor, or a spur gear multi-stage reducer motor. The connection method between the boiler shaft motor 12 and the boiler shaft 11 varies depending on the type of motor. It can be a conventional connection method used in the mechanical field.

[0035] The key improvement of this invention lies in: Figure 2 and Figure 3 As shown, a positioning sleeve 5 is fitted onto the rotating shaft 33, and the positioning sleeve 5 is fixedly connected to the pot shaft 11, as shown. Figure 5 As shown, the positioning bushing 5 can also be fixedly connected to the housing 20 of the wok device. A first irregular structure is provided between the positioning bushing 5 and the rotating shaft 33, which can move the rotating shaft 33 up and down when the rotating shaft 33 rotates relative to the positioning bushing 5.

[0036] The first irregular structure mainly includes the following types of structures:

[0037] 1) such as Figure 3 and Figure 6As shown, the first irregular structure consists of a protrusion 41 on the outer peripheral wall of the rotating shaft 33 and a closed-loop slide 42 on the inner wall of the positioning sleeve 5 opposite to the protrusion 41. The trajectory formed by the slide 42 on the inner wall of the positioning sleeve 5 is a curved pattern that moves up and down along its axial direction. That is, when the positioning sleeve is unfolded into a plane, the slide 42 is a curved pattern that undulates up and down. The protrusion 41 is embedded in the slide 42.

[0038] The unfolded planar 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 planar shape of the slide 42 is a sine wave; the height and frequency of the fork blade moving up and down in the wok 10 are determined by the shape of the slide 42. For example, within the same circumference, the greater the difference between the peak value and the trough value of the sine wave, the higher the height of the fork blade 32 moving up and down; the shorter the period of the sine wave, the higher the frequency of the fork blade 32 moving up and down.

[0039] The specific installation of this structure: as follows Figure 7 As shown, an insertion track 51 extending vertically upwards is provided inside the positioning sleeve 5 at a position corresponding to the highest point of the slide rail 42. When the positioning sleeve 5 is fitted onto the rotating shaft 33, the protrusion 41 is inserted along the insertion track 51 and finally placed inside the slide rail 42. After the protrusion 41 is installed in the track, the protrusion 41 is confined within the slide rail 42 by a retaining spring 52 located at the highest point of the slide rail 42 and embedded in the inner wall of the positioning sleeve 5, preventing the protrusion 41 from sliding out of the insertion track 51 during movement. Finally, the positioning sleeve 5 is fixed to the pot shaft 11 or the housing 20 by 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 configured as a component that can elastically extend and retract 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 inserted into the positioning sleeve 5 and is kept 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. Under the action of the spring, the protrusion 41 is popped out and embedded in the slide 42.

[0041] 2) This structure is based on the same principle as the first structure, except that the positions of the protrusion 41 and the slide 42 are reversed. That is, the first irregular structure includes a protrusion 41 on the inner peripheral wall of the positioning bushing 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 position of 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. The protrusion 41 is embedded in the slide 42.

[0042] The specific installation of this structure is as follows: The positioning bushing 5 is provided with a mounting hole for a protrusion 41. First, the positioning bushing 5 is fitted onto the rotating shaft 33. Then, the protrusion 41 is inserted from the mounting hole for the protrusion 41 and the inner end of the protrusion 41 is placed in the slide rail 42. The protrusion 41 and the mounting hole for the protrusion 41 can be connected by snap-fit ​​or by threaded engagement.

[0043] This invention achieves the up-and-down movement of one of the components by setting slide rails 42 and protrusions 41 on two components that rotate relative to each other. The protrusions 41 are embedded in the slide rails 42. During the relative rotational movement, the protrusions 41 are pushed to slide in the slide rails 42 with concave and convex curves, thereby achieving the up-and-down movement of one of the components. It achieves a reliable functional design with a clever and simple structure.

[0044] In the structure of type "1)" or "2)", the number of protrusions 41 is at least one. When the number of protrusions 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 on the same axis), the slide 42 can be an irregular closed-loop curve type. That is, the rotating shaft 33 carries the fork blade 32 and rotates relative to the wok 10 for one revolution. The height and frequency of its up and down movement are varied. The irregularly shaped slide 42 can realize diverse stir-frying during the stirring process of the fork blade 32.

[0045] When there are two protrusions 41, the two protrusions 41 are located in the same vertical plane passing through the axis of rotation 33. The distribution of the two protrusions 41 in this structure is preferably as follows:

[0046] A. As Figure 3 As shown, the two protrusions 41 are arranged symmetrically on the same horizontal plane and along the axis of the rotating shaft 33. The two protrusions 41 are embedded in the same slide rail 42. During the up-and-down movement of the rotating shaft 33, the two protrusions 41 move along the same trajectory in the slide rail 42.

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

[0048] B, such as Figure 9 As shown, the two protrusions 41 are staggered vertically and arranged relative to each other with respect to the axis of the rotating shaft 33. In this structure, there are two slides 42, which are also staggered vertically. During the process of the rotating shaft 33 moving up and down in the positioning sleeve 5, the two protrusions 41 move along the same trajectory in the corresponding slides 42 and the two trajectories do not overlap.

[0049] The double protrusions 41 are supported by two slide rails 42, which ensures smooth sliding while allowing for various movement heights and frequencies to be set within one rotation cycle.

[0050] When there are multiple bumps 41, the trajectory of the slide 42 is determined by the specific distribution position of the bumps 41. Preferably, the multiple bumps 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; it can also be partially sleeved on the lower end of the pot shaft 11 and fixed to the pot shaft 11; or it can be directly fixed on the pot shaft 11 by means of an auxiliary frame or the like.

[0052] After installation using the above three methods, the positioning bushing 5, rotating shaft 33, and pot shaft 11 are all coaxial.

[0053] Based on the above structure, the wok 10 and the toggle fork can operate in the following modes:

[0054] 1) When the shift fork motor 31 is not working (i.e. the rotating shaft 33 does not rotate), the pot shaft motor 12 drives the pot shaft 11 to rotate synchronously with the wok 10 and the positioning sleeve 5. During the rotation of the positioning sleeve 5, the protrusion 41 on the rotating shaft 33 is passively slid in the slide 42, which causes the rotating shaft 33 to move up and down with the shift fork blade 32.

[0055] In this case, only one component needs to be driven to rotate to achieve the relative rotation and vertical movement of the two components simultaneously.

[0056] 2) The fork motor 31 drives the rotating shaft 33 to rotate with the fork blade 32, while the pot shaft motor 12 drives the pot shaft 11 to rotate at different speeds (in the same direction or in opposite directions). That is, the rotating shaft 33 and the positioning sleeve 5 rotate relative to each other, so that the protrusion 41 on the rotating shaft 33 can slide in the slide 42 of the positioning sleeve 5, thereby causing the rotating shaft 33 to rotate with the fork blade 32 relative to the wok 10 while moving up and down.

[0057] 3) The fork motor 31 drives the rotating shaft 33 to rotate with the fork blade 32, while the pot shaft motor 12 drives the pot shaft 11 to rotate in the opposite direction at the same speed. That is, the rotating shaft 33 and the positioning sleeve 5 generate relative rotation, so that the protrusion 41 on the rotating shaft 33 can slide in the slide 42 of the positioning sleeve 5, thereby causing the rotating shaft 33 to move up and down with the fork blade 32 while rotating relative to the wok 10.

[0058] 4) When the pot shaft motor 12 is not working, the shift fork motor 31 drives the rotating shaft 33 to rotate with the shift fork blade 32. The protrusion 41 on the rotating shaft 33 slides in the slide 42 of the positioning bushing 5, thereby causing the rotating shaft 33 to move up and down with the shift fork blade 32.

[0059] When the positioning bushing 5 is fixed on the housing 20, the rotation of the wok 10 does not affect the rotation and vertical 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 vertical movement of the wok 10 and the fork blade 32 can be achieved.

[0060] Furthermore, in order to enable the wok 10 to move up and down, a wok shaft 11 positioning sleeve is fitted on the wok shaft 11 and the wok shaft 11 positioning sleeve is fixed on the housing 20. A second irregular structure that enables the wok 10 to move up and down is provided between the outer peripheral wall of the wok shaft 11 and the inner wall of the wok shaft 11 positioning sleeve.

[0061] The second irregular structure is the same as the first irregular structure in terms of both structure and working principle, and will not be described further.

[0062] By moving the wok up and down 10 times, you can achieve an effect similar to a chef tossing the wok during the stir-frying process.
