[0031] I. Housing module 1 for installing the wok driving assembly (hereinafter referred to as housing module 1)

[0032] The housing module 1 of the present utility model is applicable to the wok device 10 of an intelligent cooking machine, and is particularly applicable to the wok device 10 with dual driving of the wok 2 and the fork . The present utility model is mainly an improvement for the problem that during the individual assembly of the components of the wok driving assembly in the existing wok device 10, due to assembly errors, the mechanical fit is poor, thereby affecting the product quality.

[0033] The housing module 1 of the present utility model can integrally install various components in the wok driving assembly (the wok driving assembly includes a pot driving mechanism for driving the rotation of the wok 2 and a fork driving mechanism for driving the rotation of the fork 8 in the wok 2). The housing module 1 adopts an integrally formed structural design to integrate the installation positions of various components on one component, which can reduce the connecting parts required during the assembly of scattered components. Moreover, when installing various components, there is no need for manual alignment of the installation positions, which can ensure the accuracy of the connection between components, improve the strength of the housing module 1, reduce the volume of the housing module 1, and also improve the reliability of the overall operation of the wok driving assembly.

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

[0035] 1. The main housing 11 and the main side housing 12

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

[0037] Specifically, the main housing 11 is in a shape similar to a cylinder. Both the upper and lower end faces of the main housing 11 are open, and a main cavity 111 communicating with the upper and lower openings is provided inside the main housing 11.

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

[0039] Specifically, the cavity wall of the main cavity 111 is stepped. The oil seal installation position 112 is composed of the table surface of the first step and the slope surface of the second step. The table surface of the second step and the slope surface of the third step form the pot shaft bearing installation position 113. The table surface of the third step and the slope surface of the fourth step form the main worm gear installation position 114. The cover plate installation position 115 is composed of the table surface of the fourth step and an annular convex edge extending upward along the table surface of the fourth step. Each installation position is sequentially connected in the main cavity 111, with distinct levels.

[0040] Preferably, as Figure 2 shown, 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 housing 11 in such a way that it passes through the main housing 11, and the oil seal 51, the pot shaft bearing 52, and the main worm wheel 53 are all sleeved thereon. The upper end of the pot shaft 5 passes through the shaft hole 152 on the cover plate 15 and is connected to the bottom of the frying pan 2. The lower end of the pot shaft 5 passes through the lower open end of the main housing 11 and extends downward. The main worm wheel 53 is fixedly connected to the pot shaft 5 and drives the pot shaft 5 to rotate synchronously with the frying pan 2. Based on the integrated structure, by providing an oil seal 51 at the bottom of the main cavity 111 to dynamically seal the gap between the pot shaft 5 and the lower open end of the main housing 11, a cavity capable of containing liquid and semi-fluid lubricants can be formed in the main cavity 111.

[0042] In the present utility model, the installation positions of the components for positioning and driving the pot shaft 5 are integrated in the main cavity 111 of one component by means of integral molding. Only by placing the components in the corresponding installation positions can the coaxial installation of the pot shaft 5 and the main cavity 111 be achieved, which can ensure the assembly accuracy and reduce the assembly error during manual positioning and installation.

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

[0044] Furthermore, as Figures 2-3 shown, in order to dynamically seal between the pot shaft 5 and the shaft hole 152, a convex platform 151 protruding upward is provided in the middle area of the pot shaft bearing installation position 113 of the cover plate 15 where the other pot shaft bearing 52 is located. The shaft hole 152 is provided at the center of the top surface of the convex platform 151, and an oil seal 51 sleeved on the pot shaft 5 is provided in the convex platform 151. A sealing ring 17 is provided at the connection between the cover plate 15 and the main housing 11.

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

[0046] Specifically, a part of the outer peripheral wall of the main side housing 12 is embedded in the peripheral wall of the main housing 11, and the axis of the hollow main channel is perpendicular to the axis of the main cavity 111. The hollow main channel penetrates both ends of the main side housing 12, and a pot shaft motor installation position 121 is provided on the end surface of one end of the main side housing 12.

[0047] Preferably, circular ring portions 122 extend outward along the circumferential direction of the end wall of the main body portion at both ends of the main side housing 12. The pot shaft motor installation position 121 is composed of a plurality of installation holes on the circular ring portion 122. The main body of the pot shaft motor 55 is locked to the pot shaft motor installation position 121 by screws, and the power output shaft 551 of the pot shaft motor 55 extends into the hollow main channel and is connected to the main worm 54 of the main worm gear assembly.

[0048] To rotatably support the main worm 54 within the hollow main channel, main worm bearing mounting positions 123 for mounting two main worm bearings 541 of the main worm assembly are respectively provided at both ends of the hollow main channel, and the main worm 54 is mounted within the hollow main channel via the two main worm bearings 541.

[0049] An oil seal 51 is provided within the circular ring portion 122 where the pot shaft motor 55 is installed, and a sealing baffle 124 is provided on another circular ring portion 122 to seal both ends of the hollow main channel.

[0050] Furthermore, the hollow main channel communicates with the main cavity 111 through a main window hole 125 provided on the cavity wall of the main cavity 111 opposite to the main worm gear mounting position 114, thereby realizing the external meshing drive 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 in a reverse stepped shape corresponding to the inner wall, and to strengthen the strength of the main housing 11, a number of reinforcing ribs are provided on the outer wall of the main housing 11.

[0052] In this application, each component of the pot driving mechanism is integrally installed within the integrally formed main housing 11 and main side housing 12. This integrated installation of the integrated structure not only helps to improve the connection accuracy between each component, but also facilitates sealing. This structure can directly pour lubricating oil into the main cavity 111 and the hollow main channel to lubricate the mechanical transmission components. Compared with the structure in the prior art where only grease can be used for the driving device, the lubricating oil can come into contact with the mechanical components over a larger area, resulting in better lubrication effect. At the same time, the lubricating oil can also promote heat dissipation.

[0053] 2. Sub-housing 13 and sub-side housing 14

[0054] The sub-housing 13 and sub-side housing 14 are used to mount the fork drive shaft 6, drive shaft bearing 61, sub-worm gear 62, sub-worm assembly, and fork motor 64 of the fork driving mechanism.

[0055] As Figures 4-6 shown, the lower end of the fork shaft 65 (the shaft connected to the fork within the frying pan 2) of the fork driving mechanism is connected to the fork drive shaft 6 through a fork gear transmission mechanism (including a driving gear 71 and a driven gear 72). The upper end of the fork shaft 65 passes through the hollow cavity of the pot shaft 5 into the frying pan 2. That is, the pot shaft 5 and the fork shaft 65 are sleeved coaxially and respectively act on the frying pan 2 and the fork 8 within the frying pan 2. In the prior art, it is difficult to perform coaxial positioning installation on the fork shaft 65 and the fork drive shaft 6, and ensuring the accuracy of the center distance between the fork drive shaft 6 and the fork shaft 65 is also a key factor affecting the stable operation of the fork driving mechanism.

[0056] In this application, the auxiliary housing 13 is arranged beside one side of the main housing 11 and integrally formed with the main housing 11. This structure can ensure that there will be no relative displacement or misalignment caused by installation or deformation when the main housing 11 and the auxiliary housing 13 are separate components. This structure can ensure that the axis of the main cavity 111 of the main housing 11 and the axis of the auxiliary cavity of the auxiliary housing 13 always remain parallel.

[0057] Therefore, only need to install the fork transmission shaft 6 coaxially with the auxiliary cavity in the auxiliary cavity, and at the same time coaxially sleeve the fork shaft 65 with the pot shaft 5 (the pot shaft 5 is coaxial with the main cavity 111) (a bearing is sleeved on the fork shaft 65 to achieve the positioning and relative rotation between the fork shaft 65 and the pot shaft 5), then the accuracy of the center distance between the fork shaft 65 and the fork transmission shaft 6 can be ensured, thereby improving the operating performance of the fork driving mechanism.

[0058] The structure of the auxiliary housing 13 is similar to that of the main housing 11. The outer contour of the auxiliary housing 13 is stepped. Correspondingly, the cavity wall of the auxiliary cavity is also stepped, specifically in the shape of an inverted step, and the lower end face of the auxiliary housing 13 is open.

[0059] In this auxiliary cavity, there are successively arranged from top to bottom a transmission shaft bearing installation position 131 for installing the transmission shaft bearing 61, a secondary worm gear installation position 132 for installing the secondary worm gear 62, and a bottom shell installation position 133 for installing the bottom shell 16 that can enclose the transmission shaft bearing 61 and the secondary worm gear 62 in the auxiliary cavity.

[0060] The transmission shaft bearing installation position 131 is composed of the table surface of the first step and the slope surface of the second step (the first step to the third step from top to bottom). The table surface of the second step and the slope surface of the third step form the secondary worm gear installation position 132. The bottom shell installation position 133 is composed of the table surface of the third step and the slope surface of the fourth step. Each installation position is successively connected in the auxiliary cavity, with distinct levels.

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

[0062] Similarly, by integrally forming the transmission shaft bearing installation position 131 and the secondary worm gear installation position 132 in the auxiliary cavity, only need to place each component in the corresponding installation position, then the coaxial installation of the fork transmission shaft 6 and the auxiliary cavity can be realized.

[0063] Preferably, the bottom case 16 has a stepped structure with an oil seal mounting position 112 and another transmission shaft bearing mounting position 131. An oil seal 51 is installed by arranging the oil seal mounting position 112 on the outer periphery of the central through hole 161 of the bottom case 16 to dynamically seal the gap between the shift fork transmission shaft 6 and the central through hole 161. Meanwhile, a static sealing ring 17 is arranged at the connection position between the bottom case 16 and the secondary case 13, so as to form a cavity in the secondary cavity that can hold liquid lubricant.

[0064] Another transmission shaft bearing mounting position 131 is arranged in the bottom case 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 secondary cavity.

[0065] To make the housing module 1 structure compact, the main case 11 and the secondary case 13 are arranged in an overlapping manner with vertical dislocation and intersection, that is, the stepped surfaces in the middle of the outer wall of the main case 11 overlap with the stepped surfaces in the middle of the outer wall of the secondary case 13, making full use of the space on the stepped surfaces of the main case 11 and the secondary case 13 for connection, and further reducing the overall volume occupied by the housing module 1.

[0066] The secondary side case 14 is arranged on one side of the secondary case 13. The secondary side case 14 has a hollow secondary channel for installing the secondary worm assembly, and the axis of the hollow secondary channel is perpendicular to the axis of the secondary cavity.

[0067] Specifically, the secondary worm assembly includes a secondary worm 63 and two secondary worm bearings 631. The two secondary worm bearings 631 are respectively placed at both ends of the hollow secondary channel, and the secondary worm 63 is rotatably supported in the hollow secondary channel in a coaxial manner with the hollow secondary channel through the secondary worm bearings 631.

[0068] The hollow secondary channel communicates with the secondary cavity through a secondary window hole 142 arranged on the cavity wall of the secondary cavity opposite to the secondary worm gear mounting position 132, thereby realizing the external meshing transmission connection between the secondary worm 63 and the secondary worm gear 62.

[0069] A shift fork shaft motor mounting position 141 is provided on one end face of the secondary side case 14. The main body of the shift fork shaft motor is locked to the shift fork shaft motor mounting position 141 by screws, and the power output shaft 551 of the shift fork shaft motor extends into the hollow secondary channel and is connected to the secondary worm 63.

[0070] The structure of the secondary side case 14 is the same as that of the main side case 12, so it will not be repeated here.

[0071] Similarly, the secondary case 13 and the secondary side case 14 can also be sealed by filling with lubricating oil.

[0072] To make the overall structure square and occupy less space, the axis of the hollow main channel is parallel to the axis of the hollow sub-channel, and the pot shaft motor mounting position 121 and the fork shaft motor mounting position are on the same side.

[0073] As Figure 1 and Figure 7 shown, for facilitating the installation of the housing module 1 on the housing 3 of the frying pan device 10, a plurality of screw holes 18 are provided on the top side edges of the main housing 11 and the sub-housing 13. Since the top surface of the sub-housing 13 is lower than the top surface of the main housing 11, the side of the sub-housing 13 is provided with studs 19 so that the top surfaces of the screw holes 18 on the main housing 11 and the screw holes 18 on the studs 19 are on the same horizontal plane. After integrating and installing the pot driving mechanism and the fork driving mechanism in the housing module 1 to form a standardized modular component, the entire modular component is horizontally installed on the housing 3 through the screw holes 18, which simplifies the assembly process and can ensure the installation accuracy between components.

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

[0075] As Figure 7 and Figure 8 shown, the frying pan device 10 includes a frying pan 2, a heater 4 for heating the frying pan 2, and a housing 3 for supporting the frying pan 2 and the heater 4. Two support shafts are symmetrically provided on the outer side of the housing 3, and the frying pan device 10 is mounted on the frame of the intelligent cooking machine through the support shafts.

[0076] The improvement of the frying pan device 10 of the present utility model lies in that the frying pan device 10 further includes an integral standard base provided in the housing 3 and a driving component mounted on the standard base. The standard base is the above-mentioned housing module 1; the driving component is composed of the above-mentioned pot driving mechanism for driving the frying pan 2 to rotate and the fork driving mechanism for driving the fork provided in the frying pan 2 to rotate.

[0077] The frying pan device 10 of the present utility model can integrally install various components (such as the pot shaft 5, the main worm gear 53, the main worm 54, the pot shaft motor 55, the fork transmission shaft 6, the sub-worm gear 62, the sub-worm 63, and the fork motor 64, etc.) in the driving component, and form a modular standard component for production and assembly, increasing the installation convenience through modularization. Compared with the installation of the existing frying pan driving component, it effectively reduces the number of parts, simplifies the internal assembly structure of the frying pan device 10, improves the assembly accuracy, and saves the internal space of the frying pan device 10 at the same time.

[0078] The frying pan device 10 of the present utility model adopts a worm and 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 original spur multi-stage reduction mechanism in the prior art requires multi-stage reduction to obtain a large reduction ratio within a limited volume space. The outer diameter of the gear is small, the module is small, and the tooth thickness is thin, resulting in low strength. Under the working conditions of high load and high strength during stir-frying, the gears in the reduction box are prone to wear and have poor durability.

[0080] However, the one-stage reduction of the transposed worm and worm gear of the present utility model can obtain a large torque and a large transmission ratio within a limited volume space.

[0081] Moreover, the outer diameter of the worm gear is large, the module is large, and the tooth strength is high, greatly improving the stability and reliability of the driving mechanism.

[0082] In addition, the worm and worm gear has good self-locking property, which is convenient for disassembling and assembling the frying pan 2.

[0083] The operation process of the frying pan device 10 of the present utility model:

[0084] 1) When it is necessary to drive the frying pan 2 to rotate, start the pot shaft motor 55. The power output shaft 551 of the pot shaft motor 55 drives the main worm 54 to rotate and drives the main worm gear 53 to rotate, so that the pot shaft 5 fixed to the main worm gear 53 drives the frying pan 2 to rotate synchronously.

[0085] 2) When it is necessary to drive the fork 8 in the frying pan 2 to rotate, start the fork motor 64. The output shaft of the fork motor 64 drives the secondary worm 63 to rotate and drives the secondary worm gear 62 to rotate, thereby driving the fork transmission shaft 6 to rotate.
