Embodiment of the present application

[0031] I. Shell module 1 for installing wok driving assembly in intelligent wok cooking machine (hereinafter referred to as shell module 1)

[0032] The housing module 1 of the present invention is applicable to the wok device 10 of the intelligent cooking machine, and is particularly applicable to the wok device 10 with dual drive of wok 2 and fork 8. The present invention is mainly an improvement to address the problem that poor mechanical fit caused by assembly errors during the assembly of each component of the wok drive assembly in the existing wok device 10, which in turn affects product quality.

[0033] The housing module 1 of the present invention can integrate and install various components in the wok driving assembly (the wok driving assembly includes a pot driving mechanism that drives the wok 2 to rotate and a fork driving mechanism that drives the inner fork 8 of the wok 2 to rotate). The housing module 1 adopts an integral molding structure design to integrate the mounting positions of various components on one part, which can reduce the number of connecting parts required when assembling scattered parts. Moreover, when installing various components, there is no need to manually check the installation position, which can ensure the accuracy of the connection between components. While improving the strength of the housing module 1 and reducing the volume of the housing module 1, it also improves the overall reliability of the wok driving assembly.

[0034] Preferably, the housing module 1 is integrally formed by die casting of aluminum material, as shown in Figures 1-6. The housing module 1 includes a main shell 11, a main side shell 12, a secondary shell 13, and a secondary side shell 14.

[0035] 1. Main shell 11 and main side shell 12

[0036] The main shell 11 and the main side shell 12 are used to install the pot drive mechanism, which includes a pot shaft 5, an oil seal 51, a pot shaft bearing 52, a main worm gear 53, a main worm assembly, and a pot shaft motor 55, all fixed to the bottom of the pot body.

[0037] Specifically, the main shell 11 is cylindrical in shape, with both the upper and lower ends of the main shell 11 being open, and a main cavity 111 connecting the upper and lower openings is provided inside the main shell 11.

[0038] Within the main cavity 111, from bottom to top, there are sequentially arranged an oil seal mounting position 112 for installing the oil seal 51, a boiler shaft bearing mounting position 113 for installing the boiler shaft bearing 52, a main worm gear mounting position 114 for installing the main worm gear 53, and a cover plate mounting position 115 for installing a cover plate 15 that can enclose the oil seal 51, boiler shaft bearing 52, and main worm gear 53 within the main cavity 111.

[0039] Specifically, the cavity wall of the main cavity 111 is stepped. The oil seal mounting position 112 is formed by the platform of the first step and the slope of the second step. The platform of the second step and the slope of the third step form the pot shaft bearing mounting position 113. The platform of the third step and the slope of the fourth step form the main worm gear mounting position 114. The cover plate mounting position 115 is formed by the platform of the fourth step and an annular protrusion extending upward along the platform of the fourth step. The mounting positions are connected sequentially within the main cavity 111, with clear layers.

[0040] Preferably, as shown in Fig. 2, when the oil seal 51, the pot shaft bearing 52, the main worm gear 53 and the cover plate 15 are all installed in the corresponding installation positions, the oil seal 51, the pot shaft bearing 52, the main worm gear 53 and the cover plate 15 are all coaxial with the main cavity 111.

[0041] The pot shaft 5 is installed on the main shell 11 in a manner that penetrates the main shell 11 and that the oil seal 51, the pot shaft bearing 52 and the main worm gear 53 are all sleeved on the pot shaft 5, the upper end of the pot shaft 5 penetrates the shaft hole 152 on the cover plate 15 and is connected with the bottom of the wok 2, the lower end of the pot shaft 5 extends downward through the lower opening of the main shell 11, the main worm gear 53 is fixedly connected on the pot shaft 5 and drives the pot shaft 5 to rotate synchronously with the wok 2. Based on the integrated structure, the gap between the pot shaft 5 and the lower opening of the main shell 11 is dynamically sealed by arranging the oil seal 51 at the bottom of the main cavity 111, so that a cavity for containing liquid and semi-fluid lubricants is formed in the main cavity 111.

[0042] The present application integrates the installation positions of the components for positioning and driving the pot shaft 5 in the main cavity 111 of one component by the integrated molding manner, so that the coaxial installation of the pot shaft 5 and the main cavity 111 can be realized by only placing the components in the corresponding installation positions, which can ensure the assembly precision and reduce the assembly error caused by the manual positioning and installation.

[0043] Preferably, in order to further limit the radial position of the pot shaft 5 and avoid the shaking of the pot shaft 5 during the rotation, another pot shaft bearing 52 is arranged between the cover plate 15 and the pot shaft 5.

[0044] Further, as shown in Figs. 2-3, in order to dynamically seal the gap between the pot shaft 5 and the shaft hole 152, the boss 151 protruding upward is arranged in the middle area of the pot shaft bearing installation position 113 of the other pot shaft bearing 52 on the cover plate 15, the shaft hole 152 is arranged at the central area of the top surface of the boss 151, and the oil seal 51 is arranged in the boss 151 and sleeved on the pot shaft 5. The sealing ring 17 is arranged at the connection between the cover plate 15 and the main shell 11.

[0045] The main side shell 12 is mainly used for installing the main worm assembly and the pot shaft motor 55, is arranged on one side of the main shell 11, and is a hollow column with a hollow main channel, and the main worm assembly is installed in the hollow main channel.

[0046] Specifically, the outer peripheral wall of the main side shell 12 is embedded in the peripheral wall of the main shell 11, the axis of the hollow main channel is perpendicular to the axis of the main cavity 111, the hollow main channel penetrates through both ends of the main side shell 12, and the pot shaft motor installation position 121 is arranged on the end face of one end of the main side shell 12.

[0047] Preferably, both ends of the main side shell 12 have annular portions 122 extending outward along the circumferential direction of the end wall of its main body. The pot shaft motor mounting position 121 is composed of multiple mounting holes on the annular portions 122. The main body of the pot shaft motor 55 is locked to the pot shaft motor mounting position 121 by screws. The power output shaft 551 of the pot shaft motor 55 extends into the hollow main channel and connects with the main worm 54 of the main worm assembly.

[0048] To enable the main worm gear 54 to be rotatably supported within the hollow main channel, two main worm gear bearing mounting positions 123 for mounting the main worm gear assembly are provided at both ends of the hollow main channel. The main worm gear 54 is supported within the hollow main channel by the two main worm gear bearings 541.

[0049] An oil seal 51 is provided in the annular part 122 where the boiler shaft motor 55 is installed, and a sealing baffle 124 is provided on another annular part 122 to seal both ends of the hollow main channel.

[0050] Furthermore, the hollow main channel is connected to the main cavity 111 through the main window hole 125 on the cavity wall of the main cavity 111 opposite to the main worm gear mounting position 114, thereby realizing the external meshing transmission connection between the main worm 54 and the main worm gear 53.

[0051] To reduce the weight of the housing module 1, the outer wall of the main housing 11 is also inverted stepped, corresponding to the inner wall, and to strengthen the main housing 11, a number of reinforcing ribs are provided on the outer wall of the main housing 11.

[0052] This application integrates the various components of the pot drive mechanism into the integrally formed main shell 11 and main side shell 12. This integrated installation not only improves the connection accuracy between the components but also facilitates sealing. This structure allows lubricating oil to be directly injected into the main cavity 111 and the hollow main channel to lubricate the mechanical transmission components. Compared with the existing technology where the drive device can only use grease, the lubricating oil can have a larger contact area with the mechanical components, resulting in better lubrication. At the same time, the lubricating oil can also promote heat dissipation.

[0053] 2. Secondary shell 13 and secondary lateral shell 14

[0054] The secondary housing 13 and secondary side housing 14 are used to install the shift fork drive mechanism, including the shift fork drive shaft 6, drive shaft bearing 61, secondary worm gear 62, secondary worm assembly, and shift fork motor 64.

[0055] As shown in FIG. 4-6, the lower end of the fork shaft 65 (the shaft connected with the fork inside the wok 2) is connected with the fork transmission shaft 6 through the fork gear transmission mechanism (including the driving gear 71 and the driven gear 72), and the upper end of the fork shaft 65 is passed into the wok 2 through the hollow cavity of the pot shaft 5, that is, the pot shaft 5 and the fork shaft 65 are coaxially sleeved to act on the wok 2 and the fork 8 inside the wok 2 respectively. In the prior art, it is difficult to coaxially position and install the fork shaft 65 and the fork transmission shaft 6, and the accuracy of the center distance between the fork transmission shaft 6 and the fork shaft 65 is a key factor affecting the stable operation of the fork driving mechanism.

[0056] The present application sets the auxiliary shell 13 on one side of the main shell 11 and integrally forms the auxiliary shell 13 with the main shell 11. This structure can ensure that the main shell 11 and the auxiliary shell 13 will not be relatively displaced or misaligned due to installation or deformation when they are separate components. This structure can ensure that the axis of the main cavity 111 of the main shell 11 and the axis of the auxiliary cavity of the auxiliary shell 13 always remain parallel.

[0057] Therefore, the fork transmission shaft 6 is only needed to be installed in the auxiliary cavity in a coaxial manner with the auxiliary cavity, and the fork shaft 65 is coaxially sleeved with the pot shaft 5 (the pot shaft 5 is coaxial with the main cavity 111) (the positioning and relative rotation between the fork shaft 65 and the pot shaft 5 are realized by sleeving a bearing on the fork shaft 65), which can ensure the accuracy of the center distance between the fork shaft 65 and the fork transmission shaft 6, thereby improving the operation performance of the fork driving mechanism.

[0058] The structure of the auxiliary shell 13 is similar to that of the main shell 11. The outer contour of the auxiliary shell 13 is stepped, and correspondingly, the cavity wall of the auxiliary cavity is also stepped, specifically inverted stepped, and the lower end surface of the auxiliary shell 13 is open.

[0059] The transmission shaft bearing installation site 131 for installing the transmission shaft bearing 61, the auxiliary worm gear installation site 132 for installing the auxiliary worm gear 62, and the bottom shell installation site 133 for installing the bottom shell 16 that can enclose the transmission shaft bearing 61 and the auxiliary worm gear 62 in the auxiliary cavity are sequentially arranged in the auxiliary cavity from top to bottom.

[0060] The transmission shaft bearing installation site 131 is composed of the mesa of the first step and the slope surface of the second step (the first step to the third step from top to bottom), the mesa of the second step and the slope surface of the third step constitute the auxiliary worm gear installation site 132, and the mesa of the third step and the slope surface of the fourth step constitute the bottom shell installation site 133. The installation sites sequentially connect in the auxiliary cavity and are clearly layered.

[0061] The upper end of the shift fork transmission shaft 6 penetrates the center through hole 161 of the bottom shell 16 and is rotatably positioned in the auxiliary cavity through the transmission shaft bearing 61, and the auxiliary worm wheel 62 is fixedly sleeved on the shift fork transmission shaft 6, the lower end of the shift fork transmission shaft 6 is fixedly connected with the driving gear 71, and the lower end of the shift fork shaft 65 is connected with the driven gear 72, and the driving gear 71 and the driven gear 72 are externally meshed.

[0062] Similarly, the transmission shaft bearing installation position 131 and the auxiliary worm wheel installation position 132 are integrated in the auxiliary cavity in an integral molding manner, and only by placing each component in the corresponding installation position, the coaxial installation of the shift fork transmission shaft 6 and the auxiliary cavity can be realized.

[0063] Preferably, the bottom shell 16 is a stepped structure with an oil seal installation position 112 and another transmission shaft bearing installation position 131, the oil seal 51 is installed by arranging the oil seal installation position 112 on the outer periphery of the center through hole 161 of the bottom shell 16 to dynamically seal the gap between the shift fork transmission shaft 6 and the center through hole 161, and a static seal ring 17 is arranged at the joint position of the bottom shell 16 and the auxiliary shell 13 to form a cavity in the auxiliary cavity for containing liquid lubricant.

[0064] Another transmission shaft bearing installation position 131 is arranged in the bottom shell 16 to position the shift fork transmission shaft 6 through the upper and lower transmission shaft bearings 61, further ensuring that the shift fork transmission shaft 6 is coaxially arranged with the auxiliary cavity.

[0065] In order to make the shell module 1 compact, the main shell 11 and the auxiliary shell 13 are arranged in an upper-lower staggered cross-over manner, that is, the stepped surface in the middle of the outer wall of the main shell 11 overlaps with the stepped surface in the middle of the outer wall of the auxiliary shell 13, the space on the stepped surfaces of the main shell 11 and the auxiliary shell 13 is utilized for connection, and the overall volume occupied by the shell module 1 is further reduced.

[0066] The auxiliary side shell 14 is arranged on one side of the auxiliary shell 13, and the auxiliary side shell 14 has a hollow auxiliary passage for installing an auxiliary worm assembly, and the axis of the hollow auxiliary passage is perpendicular to the axis of the auxiliary cavity.

[0067] Specifically, the auxiliary worm assembly includes an auxiliary worm 63 and two auxiliary worm bearings 631, and the two auxiliary worm bearings 631 are arranged at the two ends of the hollow auxiliary passage, and the auxiliary worm 63 is rotatably supported in the hollow auxiliary passage through the auxiliary worm bearings 631 in a coaxial manner with the hollow auxiliary passage.

[0068] The hollow auxiliary passage is communicated with the auxiliary cavity through the auxiliary window hole 142 arranged on the cavity wall of the auxiliary cavity opposite to the auxiliary worm wheel installation position 132, and the external meshing transmission connection between the auxiliary worm 63 and the auxiliary worm wheel 62 is realized.

[0069] A yoke shaft motor installation position 141 is arranged on one end surface of the secondary side shell 14, the main body of the yoke shaft motor is locked on the yoke shaft motor installation position 141 by screws, and the power output shaft 551 of the yoke shaft motor extends into the hollow secondary channel and is connected with the secondary worm 63.

[0070] The structure of the secondary side shell 14 is the same as that of the primary side shell 12, and is not repeated here.

[0071] Similarly, the secondary shell 13 and the secondary side shell 14 can also be sealed by pouring lubricating oil.

[0072] In order to make the overall structure square and occupy small space, the axis of the hollow primary channel is parallel to the axis of the hollow secondary channel, and the pot shaft motor installation position 121 and the yoke shaft motor installation position are located on the same side.

[0073] As shown in FIG. 1 and FIG. 7, in order to facilitate the installation of the shell module 1 on the machine shell 3 of the frying pan device 10, a plurality of screw holes 18 are arranged on the top side of the primary shell 11 and the secondary shell 13. Since the top surface of the secondary shell 13 is lower than the top surface of the primary shell 11, the side of the secondary shell 13 is provided with a stud 19 so that the top surfaces of the screw holes 18 on the primary shell 11 and the screw holes 18 on the stud 19 are on the same horizontal plane. After the pot driving mechanism and the yoke driving mechanism are integrated and installed in the shell module 1 to form a standardized module, the entire module is installed horizontally on the machine shell 3 through the screw holes 18, which simplifies the assembly process and ensures the installation accuracy between the components.

[0074] II. The frying pan device 10 (hereinafter referred to as the frying pan device 10) in the intelligent cooking machine

[0075] As shown in FIG. 7 and FIG. 8, the frying pan device 10 includes a frying pan 2, a heater 4 for heating the frying pan 2, and a machine shell 3 for supporting the frying pan 2 and the heater 4. Two supporting shafts are symmetrically arranged outside the machine shell 3, and the frying pan device 10 is erected on the rack of the intelligent cooking machine through the supporting shafts.

[0076] The improvement of the frying pan device 10 of the present application lies in that the frying pan device 10 further comprises an integrated standard base arranged in the machine shell 3 and a driving assembly installed on the standard base, the standard base being the shell module 1 described above; and the driving assembly being composed of the pot driving mechanism for driving the frying pan 2 to rotate and the yoke driving mechanism for driving the yoke arranged in the frying pan 2 to rotate.

[0077] The wok device 10 of the present invention integrates and installs various components of the drive assembly (wok shaft 5, main worm gear 53, main worm 54, wok shaft motor 55, shift fork drive shaft 6, auxiliary worm gear 62, auxiliary worm 63, and shift fork motor 64, etc.) into modular standard parts for assembly, thereby increasing installation convenience through modularization. Compared with the installation of existing wok drive assemblies, it effectively reduces the number of parts, simplifies the internal assembly structure of the wok device 10, improves assembly accuracy, and saves internal space of the wok device 10.

[0078] The wok device 10 of the present invention adopts a worm gear transmission mechanism, which has the advantages of stable transmission and long service life compared with the gear transmission mechanism used in the prior art.

[0079] The existing spur gear multi-stage reduction mechanism requires multiple stages of reduction to achieve a large reduction ratio within a limited volume space. The gears have small outer diameters, small modules, and thin teeth with low strength. Under conditions of high load and high strength, such as cooking, the gears inside the reduction gearbox are prone to wear and have poor durability.

[0080] The transposition worm gear single-stage reduction of the present invention can obtain large torque and large transmission ratio in a limited volume space.

[0081] Furthermore, the worm gear has a large outer diameter, large module, and high tooth strength, which greatly improves the stability and reliability of the drive mechanism.

[0082] In addition, the worm gear has good self-locking properties, making it easy to disassemble and assemble the wok.

[0083] The operation process of the wok device 10 of the present invention:

[0084] When it is necessary to drive the wok 2 to rotate, the wok shaft motor 55 is started. The power output shaft 551 of the wok shaft motor 55 drives the main worm gear 54 to rotate and drives the main worm wheel 53 to rotate, so that the wok shaft 5, which is fixed to the main worm wheel 53, rotates synchronously with the wok 2.

[0085] When it is necessary to drive the fork 8 inside the wok 2 to rotate, the fork motor 64 is started. The output shaft of the fork motor 64 drives the secondary worm gear 63 to rotate and drives the secondary worm wheel 62 to rotate, thereby driving the fork transmission shaft 6 to rotate. Then, through the driving gear 71 below the fork transmission shaft 6 and the driven gear 72 below the fork shaft 65, the power is transmitted to the fork shaft 65 to drive the fork 8 inside the wok 2 to rotate.
