Description

Technical Field

[0001] The utility model relates to the technical field of automatic cooking robots, in particular to a universal anti-jump stirring mechanism and an automatic cooking machine. Background Art

[0002] With the advancement of science and technology, people's daily dietary requirements are getting higher and higher. Cooking has even developed to the point where cooking robots can replace manual automated cooking. Cooking robots can realize multiple automated functions such as cooking, frying, steaming, etc., which reduces the intensity of manual labor and has a good market prospect.

[0003] In order to realize automatic cooking, the cooking robot currently on the market is usually provided with a stirring mechanism and an electric hot pot. The stirring mechanism is provided with a stirring motor and a main stirring shovel 20' and an auxiliary stirring shovel 30' driven by the stirring motor 10'. The main stirring shovel 20' and the auxiliary stirring shovel 30' are used to stir-fry the ingredients in the electric hot pot. Figure 1 shown.

[0004] Although the main stirring shovel 20' and the auxiliary stirring shovel 30' of the existing stirring mechanism can stir-fry the ingredients in the electric hot pot, the following defects still exist:

[0005] 1. The existing stirring mechanism adopts a vertically arranged main stirring shovel 20', so that the main stirring shovel 20' vertically stirs the food in the middle of the electric hot pot; however, during the self-rotation of the vertically arranged main stirring shovel 20' and the self-rotation of the auxiliary stirring shovel 30', the rotation stress of the main stirring shovel 20' and the auxiliary stirring shovel 30' is unbalanced, resulting in the problem of bouncing of the main stirring shovel 20' and the auxiliary stirring shovel 30', and causing shaking and collision to the inner pot wall of the electric hot pot. If this continues for a long time, the service life of the cooking machine will be reduced, and the quality and efficiency of food frying will be affected.

[0006] 2. The existing stirring mechanism adopts a vertically arranged main stirring shovel 20'. Due to the limitation of the vertical angle of the main stirring shovel 20', the blade head of the main stirring shovel 20' can only stir-fry the ingredients in a small range at the bottom of the electric hot pot, and the blade head on the main stirring shovel 20' is difficult to fit tightly with the arc-shaped inner pot wall at the bottom of the electric hot pot, resulting in the main stirring shovel 20' being unable to stir-fry the ingredients in the electric hot pot fully and in a larger range, and there is a blind spot for stir-frying.

[0007] 3. The stirring transmission of the main stirring shovel 20' of the existing stirring mechanism adopts an internal gear transmission. Since the meshing contact area of ​​the internal gear transmission is large, the transmission efficiency is low, and the stress balance of the main stirring shovel 20' during rotation cannot be improved. Moreover, the internal gear transmission is difficult to adjust the transmission ratio in time according to the change of the inclination angle of the main stirring shovel 20', so the use effect is not ideal.

[0026] The feeding machine box is arranged at one side of the machine platform, and a feeding hopper which moves in a horizontal direction and is used for feeding food materials and seasonings into the electric hot pot is arranged on the feeding machine box; the control cabinet is arranged below the machine platform.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) The inclination angle of the stirring rod 1 of the main stirring shovel of the present application is set to 20±5° with respect to the vertical direction. By setting the stirring rod 1 in an inclined manner, the vertical gravity of the stirring rod 1 is decomposed into the inclined centrifugal force and the vertical gravity, thereby solving the problem of unbalanced rotational stress caused by the vertical setting of the main stirring shovel in the past; when the parallel spur gear group drives the stirring rod 1 by driving the rotation of the universal joint structure, the stirring rod 1 rotates at an inclination angle of 20±5°, and at the same time, the parallel spur gear group also drives the stirring rod 2 of the auxiliary stirring shovel, so that the stirring rod 2 revolves around the stirring rod 1, thereby improving the rotational stress balance of the stirring rods 1 and 2, and avoiding the stirring rods 1 and 2 from jumping. Therefore, the blade head will not cause shaking and collision with the inner wall of the electric hot pot, and then the blade head arranged at the lower ends of the stirring rods 1 and 2 can fully stir-fry the ingredients in the electric hot pot, thereby improving the quality and efficiency of the blade head's stir-frying of the ingredients.

[0029] (2) In addition, by setting the stirring rod 1 at an angle, the rotating stirring action of the stirring rod 1 and the stir-frying range of the blade head are larger, and the blade head can present a certain inclination following the tilting setting of the stirring rod 1, so that the blade head can be more closely fitted to the curved inner pot wall of the electric hot pot, avoiding the existence of a stir-frying blind spot of the blade head in the electric hot pot, thereby further improving the stir-frying effect and stir-frying range of the main stirring spatula on the food in the electric hot pot.

[0030] (3) The present application drives stirring rod 1 and stirring rod 2 by adopting a parallel spur gear set.

Therefore, during use, the transmission ratio can be adjusted accordingly in conjunction with the adjustment of the inclination angle of stirring rod 1, so as to further improve the rotational stress balance of stirring rod 1 and stirring rod 2 and enhance the user experience.

DETAILED DESCRIPTION

[0051] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0052] like Figure 2-10 As shown, a universal anti-jumping mixer mainly includes a main stirring shovel 801, an auxiliary stirring shovel 802, a parallel spur gear set 804, a stirring driver 805 and a universal joint structure 806. The main stirring shovel 801 has a stirring rod 8011 and a cutter head 803 movably connected to the lower end of the stirring rod 8011, and two cutter heads 803 are provided at the lower end of the stirring rod 8011. The auxiliary stirring shovel 802 has a stirring rod 8021 and a cutter head 803 movably connected to the lower end of the stirring rod 8021; the stirring driver 805 of the present application preferably adopts a stirring motor. Therefore, the stirring driver 805 is connected to the parallel spur gear set 804 by driving, so that the parallel spur gear set 804 rotates under the power provided by the stirring driver 805, and each parallel spur gear set 804 is composed of at least a pair of spur gears.

[0053] The parallel spur gear set 804 is further connected to the universal joint structure 806 and the stirring rod 2 8021, and the universal joint structure 806 is connected to the stirring rod 1 8011. Therefore, the parallel spur gear set 804 can transmit power to the stirring rod 1 8011 through the universal joint structure 806, so that the stirring rod 1 8011 rotates. The inclination angle α1 of the stirring rod 1 8011 of the present application with respect to the vertical direction is 20±5°. Specifically, as Figure 4 As shown, the inclination angle α1 of the stirring rod 1 8011 with the vertical direction is preferably set to 21°, so that the stirring rod 1 8011 rotates obliquely under the drive of the universal joint structure 806, and the ingredients in the middle of the electric hot pot 60 are stir-fried by the cutter head 803 connected to the lower end of the stirring rod 1 8011. In addition, the stirring rod 2 8021 revolves around the stirring rod 1 8011 under the transmission of the parallel spur gear set 804. In the embodiment of the present application, the stirring rod 2 8021 is also inclined with the vertical direction, and the inclination direction of the stirring rod 2 8021 is opposite to the inclination direction of the stirring rod 1 8011. In addition, the ingredients on the edge of the electric hot pot 60 are stir-fried by the cutter head 803 connected to the lower end of the stirring rod 2 8021, so that the ingredients in the electric hot pot 60 are fully stir-fried by utilizing the mutual coordination of the stirring rod 1 8011 and the stirring rod 2 8021.

[0054] Compared with the prior art, the beneficial effects of the present invention are:

[0055] By setting the stirring rod 8011 at an inclination angle of 20±5° with the vertical direction, the vertical gravity of the stirring rod 8011 is decomposed into the inclined centrifugal force and the vertical gravity, thereby solving the problem of unbalanced rotation stress caused by the vertical setting of the main stirring shovel 801 in the past; when the parallel spur gear set 804 drives the stirring rod 8011 by driving the rotation of the universal joint structure 806, the stirring rod 8011 rotates at an inclination angle of 20±5°, and the parallel spur gear set 804 also drives the auxiliary The stirring rod 8021 of the stirring shovel 802 makes the stirring rod 8021 revolve around the stirring rod 8011, thereby improving the rotational stress balance of the stirring rods 8011 and 8021, and avoiding the jumping of the stirring rods 8011 and 8021; therefore, the blade head 803 will not cause shaking and collision to the inner wall of the electric hot pot 60, and the blade head 803 arranged at the lower ends of the stirring rods 8011 and 8021 can fully stir-fry the ingredients in the electric hot pot 60.

[0056] In addition, by setting the stirring rod 8011 at an angle, the rotating stirring action of the stirring rod 8011 and the stir-frying range of the blade head 803 are larger, and the blade head 803 can present a certain inclination following the tilting setting of the stirring rod 8011, so that the blade head 803 can fit the curved inner pot wall of the electric hot pot 60 more closely, and the stir-frying trajectories between the two blade heads 803 are also spliced ​​together, which can avoid the existence of a stir-frying blind spot between the two blade heads 803 in the electric hot pot 60, so as to further improve the stir-frying effect of the main stirring shovel 801 on the ingredients in the electric hot pot 60, and improve the stir-frying range, quality and efficiency of the blade head 803 on the ingredients.

[0057] like Figure 3 As shown, the rotation speed of stirring rod 1 8011 of the present application is set to be greater than the rotation speed of stirring rod 2 8021. The rotation speed ratio between stirring rod 1 8011 and stirring rod 2 8021 can be adaptively adjusted in actual applications and will not be elaborated here.

[0058] In order to make it easier for the stirring rod 1 8011 to connect to the blade 803, the main stirring shovel 801 of the present application further comprises a stirring arm 8012, which is roughly U-shaped. Specifically, the U-shaped stirring arm 8012 comprises a horizontal arm 80121 and curved arms 80122 arranged at both ends of the horizontal arm 80121, the stirring rod 1 8011 is movably connected to the middle of the horizontal arm 80121, and the curved arms 80122 at both ends of the horizontal arm 80121 are both movably connected to the blade 803, so the stirring rod 1 8011 can fully stir-fry the ingredients in the electric hot pot 60 through the two blades 803.

[0059] like Figure 5-6 As shown, as a further preferred embodiment, the lower ends of the bent arms 80122 at both ends of the cross arm 80121 of the present application are bent and extended in opposite directions relative to the two side surfaces of the cross arm 80121. Therefore, the bending angle α2 formed between the lower end of the bent arm 80122 and the cross arm 80121 is 135±3°, and α2 is preferably set to 135°, which is smaller than the bending angle of 155° of the bent arm 80122 of the conventional vertically arranged stirring rod, so that the blade 803 at the lower end of the stirring rod 8011 can stir-fry to the stir-frying area with a higher height of the inner wall of the electric hot pot 60.

[0060] After the bent arm 80122 is bent, the length L of the bent arm 80122 extending obliquely from the lower side of the horizontal arm 80121 is 125±3mm. It is preferred to set L to 125mm, which is longer than the 110mm length of the bent arm 80122 of the vertically arranged stirring rod. As a result, the blade head 803 at the lower end of the inclined stirring rod 8011 can be more closely attached to the inner wall of the electric hot pot 60, avoiding a blind spot in stir-frying caused by the blade head 803 being unable to fit the inner wall of the electric hot pot 60.

[0061] Moreover, the two blade heads 803 on the inclined stirring rod 1 8011 can stir-fry the stir-frying area with a higher inner wall height of the electric hot pot 60. Therefore, since the blade heads 803 on the stirring rod 2 8021 of the auxiliary stirring shovel 802 are mainly used to stir-fry the ingredients on the edge of the inner wall of the electric hot pot 60, that is, the blade heads 803 on the stirring rod 2 8021 are aimed at the stir-frying area with a higher inner wall height of the electric hot pot 60, the length of the blade heads 803 on the stirring rod 2 8021 is often set to be relatively large. In this way, by setting the stir-frying area of ​​the two blade heads 803 on the stirring rod 8011 higher, and while ensuring that the stir-frying trajectories of the two blade heads 803 on the stirring rod 8011 are spliced, it can also be spliced ​​with the stir-frying trajectory of the blade head 803 on the stirring rod 8021, so the size of the blade head 803 on the stirring rod 8021 can be set smaller, which can save material costs and further improve the stir-frying range, quality and efficiency of the bottom blade head 803 on the stirring rod 8021.

[0062] like Figure 3 , 8 -9, the stirring mechanism 80 of the present application is also provided with a rotating disk 807, the rotating disk 807 is provided with a groove, and a mutually parallel convex column 1 8071 and a convex column 2 8072 are provided in the groove, the convex column 1 8071 and the convex column 2 8072 are both formed by protruding outward from the groove bottom of the groove, and the convex column 1 8071 and the convex column 2 8072 are both provided with an axial hole in the middle. The parallel spur gear set 804 has a large gear 8041 and a small gear 8042 that are parallel and meshed with each other, wherein the large gear 8041 is sleeved on the convex column 1 8071, and the small gear 8042 is sleeved on the convex column 2 8072, thereby completing the assembly of the large gear 8041 and the small gear 8042, and the assembled large gear 8041 and the small gear 8042 can be stably meshed and transmitted with each other.

[0063] Then, the output shaft 8051 of the stirring driver 805 is connected to the middle shaft hole of the boss 1 8071, so that the stirring driver 805 outputs torque to drive the rotating disk 807 and the large gear 8041 sleeved on the boss 1 8071. Since the small gear 8042 meshes with the large gear 8041, the large gear 8041 synchronously drives the small gear 8042. The stirring rod 1 8011 is connected to the small gear 8042 through the universal joint structure 806, and the stirring rod 2 8021 is connected to the rotating disk 807. Therefore, the small gear 8042 drives the stirring rod 1 8011 through the transmission universal joint structure 806, and the rotating disk 807 drives the stirring rod 2 8021, so that the stirring rod 1 8011 and the stirring rod can both rotate.

[0064] In this way, the present application drives the stirring rod 1 8011 and the stirring rod 2 8021 by using the parallel spur gear set 804. Since the parallel spur gear set 804 is an external gear meshing transmission between the large gear 8041 and the small gear 8042, the meshing contact area between the gear sets is smaller than the meshing contact area of ​​the internal gears, and has the effects of high transmission efficiency and easy adjustment of the gear set transmission ratio. Therefore, during use, the transmission ratio can be adjusted in accordance with the adjustment of the tilt angle of the stirring rod 1 8011, so as to further improve the rotational stress balance of the stirring rod 1 8011 and the stirring rod 2 8021, and improve the user's experience.

[0065] like Figure 8 As shown, in order to install the stirring mechanism 80 more stably and conveniently, a flip connecting plate 41 is provided between the stirring driver 805 and the rotating disk 807, and the flip connection is arranged horizontally, the upper side of the flip connecting plate 41 is flat, and the lower side is provided with a groove. Then, the stirring driver 805 is installed on the upper side of the flip connecting plate 41 by screws, and the rotating disk 807 is installed on the lower side of the flip connecting plate 41 by screws, and the groove of the rotating disk 807 is combined with the groove of the lower side of the flip connecting plate 41 to form an inner cavity (equivalent to a gear box) for sealing the large gear 8041 and the small gear 8042. During the installation of the stirring driver 805, the output shaft 8051 of the stirring driver 805 can penetrate the flip connecting plate 41 and be connected to the boss 8071 in the groove of the rotating disk 807. Therefore, by setting the flip connecting plate 41, the installation convenience of the stirring driver 805 and the rotating disk 807 can be improved, and the normal operation of both can be ensured.

[0066] like Figure 3 As shown, during the process of installing the stirring driver 805 and the rotating disk 807 on the flip connecting plate 41, a rotation sensor 809 is also provided on the lower side of the flip connecting plate 41. The rotation sensor 809 is preferably a photoelectric sensor. Then, a sensing sheet 810 is provided in the groove of the rotating disk 807. The sensing sheet 810 rotates with the rotating disk 807. The sensing sheet 810 can pass through the sensing area of ​​the rotating sensor 809 during the rotation, so that each time the sensing sheet 810 passes through the sensing area, it can be sensed by the rotating sensor 809, so that the number of rotations of the main stirring shovel 801 can be detected by sensing the sensing sheet 810 through the rotating sensor 809.

[0067] like Fig. 9As shown, the universal joint structure 806 of the present application comprises a universal head 1 8061, a universal head 2 8062, a universal shaft 1 8063 and a universal shaft 2 8064, wherein the universal head 1 8061 and the universal head 2 8062 are movably connected to each other, one end of the universal shaft 1 8063 is connected to the universal head 1 8061, the other end of the universal shaft 1 8063 penetrates the rotating disk 807 and is fixedly connected to the shaft hole of the pinion 8042, and the universal shaft 1 8063 is movably connected to the rotating disk 807 through the bearing 811 when penetrating the rotating disk 807, which can ensure the rotation of the universal shaft 1 8063 and improve the assembly stability of the universal shaft 1 8063. One end of the universal shaft 2 8064 is connected to the universal head 2 8062, and the other end of the universal shaft 2 8064 is connected to the stirring rod 1 8011. In actual application, the universal shaft 8063 is vertically connected to the shaft hole of the pinion 8042, and the universal head 8061 is also vertically connected to the lower end of the universal shaft 8063. Since the stirring rod 8011 needs to be tilted with respect to the vertical direction, the universal head 8062 is tiltably connected to the universal head 8061, and the flexibility of the universal joint structure 806 is utilized to make the stirring rod 8011 rotate more smoothly in the tilted state.

[0068] like Figure 3-4 As shown, the stirring mechanism 80 of the present application is provided with a universal cover 808, and the universal cover 808 is provided at the bottom end of the rotating disk 807.

[0074] The electric hot pot 60 is arranged below the mixer box 40 and is movably installed on the machine platform 20 through a support arm. Since the rotating disk 807 is installed on the lower side of the flip connecting plate 41, the main mixing shovel 801 and the auxiliary mixing shovel 802 are both arranged below the mixer box 40 and extend into the electric hot pot 60, thereby meeting the need to stir-fry the ingredients in the electric hot pot 60.

[0075] In the present application, a rocker mechanism 70 is connected to one end of the rotating shaft 31 away from the mixer box 40 and the front and rear sides of the electric hot pot 60 connected to the support arm, so as to control the flipping action of the main stirring shovel 801, the auxiliary stirring shovel 802 and the electric hot pot 60 through the rocker mechanism 70.

[0076] The feeding box 50 of the present application is arranged on the machine table 20 and on one side close to the mixer box 40, and a feeding hopper 51 is provided on the feeding box 50, which moves in the horizontal direction and is used to feed food and seasoning into the electric hot pot 60.
