Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a fork-like device and a stir-fry machine containing the fork. Background Technology

[0002] The intelligent and automated transformation of home appliances has become a trend, and the demand for automatic cooking machines for home use is growing stronger. However, current cooking machines often fail to stir-fry ingredients evenly, resulting in poor cooking performance and a subpar user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of uneven stirring of food in the existing cooking machine, and to provide a fork device and a cooking machine including the fork.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A fork-like device includes a frame and a fork body, the fork body being used to stir-fry ingredients in a wok, the fork-like device further comprising:

[0006] A first drive mechanism and a first transmission mechanism, wherein the first drive mechanism is fixed on the frame and the first transmission mechanism is connected to the shift fork body in a transmission manner, and the first drive mechanism drives the shift fork body to rotate around a first rotating shaft extending in the horizontal direction through the first transmission mechanism.

[0007] The second drive mechanism and the second transmission mechanism are fixed on the frame and are connected to the shift fork body. The second transmission mechanism drives the shift fork body to rotate around a second rotating shaft extending in the vertical direction.

[0008] In this technical solution, by setting a first driving mechanism and a first transmission mechanism, a second driving mechanism and a second transmission mechanism, the fork body is driven to rotate around a first rotating axis and a second rotating axis that are perpendicular to each other. This allows the fork device to better stir the food, improve the uniformity of stir-frying, and result in better cooking. The first driving mechanism and the second driving mechanism are respectively fixed to the frame. The first driving mechanism drives the fork body to rotate through the first transmission mechanism, and the second driving mechanism drives the fork body to rotate through the second transmission mechanism. The first and second transmission mechanisms operate independently, avoiding interference between the second driving mechanism and the first transmission mechanism during operation, or vice versa. This reduces the load on the first and second driving mechanisms during operation and improves the reliability of the fork device.

[0009] Preferably, the outer contour of the fork body is an arc shape adapted to the shape of the pot bottom.

[0010] The radial cross-sectional shape of the shift fork body is triangular, with the apex of the triangle facing the first pivot.

[0011] In this technical solution, by setting the cross-section of the fork body to be triangular, when the fork body rotates around the first axis, the food can be flipped over under the action of the fork body, further improving the cooking effect of the food.

[0012] Preferably, the second transmission mechanism includes a turbine transmission assembly, a second transmission shaft, and a belt transmission assembly. The shift fork body is connected to the belt transmission assembly, and the second drive mechanism is connected to the belt transmission assembly via the turbine transmission assembly, the second transmission shaft, and the belt transmission assembly to drive the shift fork body to rotate around the second pivot.

[0013] In this technical solution, a specific structural form of the second transmission mechanism is provided, in which the shift fork device rotates around the second shaft under the action of the second drive mechanism through the action of the turbine transmission assembly, the transmission shaft, and the belt transmission assembly.

[0014] Preferably, the first transmission mechanism includes a first transmission shaft, a gear assembly, and a rack. The gear assembly includes a first gear, a second gear, and a third gear. The first drive mechanism is connected to one end of the first transmission shaft, the first gear is located at the other end of the first transmission shaft, the first gear is driven by the rack, the second gear is coaxially arranged with the first rotating shaft, the rack is coaxially arranged with the second rotating shaft, and the rack is driven by the second gear through the third gear.

[0015] The belt drive assembly includes a drive belt and a plurality of drive pulleys, one of which is connected to the shift fork body and coaxially arranged with the first rotating shaft. The rack passes through the axis of the drive pulley connected to the shift fork body and is capable of moving relative to the drive pulley in a vertical direction.

[0016] This technical solution provides a specific structural form of the first transmission mechanism. Through the action of the first transmission shaft, gear assembly, and rack, the shift fork device rotates around the first rotating shaft under the action of the first drive mechanism. Since the rack and the second rotating shaft are coaxially arranged, when the second drive mechanism drives the shift fork body to rotate around the second rotating shaft, the horizontal position of the rack does not change, allowing the rack to maintain engagement with the first gear and preventing the operation of the second drive mechanism and the second transmission mechanism from affecting the first drive mechanism.

[0017] Preferably, the rack includes a first part and a second part. The first part has a first serration that meshes with the first gear. The second part is coaxially arranged with the first part and rotatably connected to the first part. The first part passes through the shaft of the transmission wheel. The second part is connected to the transmission wheel in the direction of rotation and rotates synchronously. The second part has a second serration that meshes with the third gear. The third gear meshes with the second gear.

[0018] In this technical solution, by setting the rack as a first part and a second part that are rotatably connected, the fork body does not interfere with each other when rotating around the first axis and the second axis. That is, the fork body can rotate around the first axis and the second axis at the same time, so that the fork body can stir the food better.

[0019] Preferably, the shift fork device further includes a shift fork shaft and a replacement mechanism. The shift fork shaft is coaxially arranged with the first rotating shaft. The shift fork shaft is detachably connected to the shift fork body through the replacement mechanism. The second gear is disposed on the shift fork shaft.

[0020] In this technical solution, by setting a replacement mechanism, the fork body can be replaced, thereby extending the service life of the cooking machine equipped with the fork device.

[0021] Preferably, there are two shift fork shafts, which are respectively disposed on both sides of the rack, and each shift fork shaft is provided with a second gear.

[0022] Preferably, the shift fork device further includes a shift fork brush, which is disposed on the outer periphery of the shift fork body. The outer periphery of the shift fork body has a mounting groove, and the shift fork brush is partially embedded in the mounting groove.

[0023] In this technical solution, by setting a fork brush, the fork device can not only be used to stir-fry food, but also to clean the cookware.

[0024] Preferably, the first drive mechanism is a motor.

[0025] Preferably, the second drive mechanism is a motor.

[0026] A cooking machine includes a pot and a fork device as described above, wherein the outer contour shape of the fork body matches the inner contour shape of the pot.

[0027] The positive and progressive effects of this utility model are as follows: by setting a first driving mechanism and a first transmission mechanism, a second driving mechanism and a second transmission mechanism, the fork body can be driven to rotate around a first rotating axis and a second rotating axis that are perpendicular to each other, so that the fork device can better stir the food, improve the uniformity of stir-frying the food, and make the food cook better.

[0061] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0062] like Figures 1-6 As shown, this embodiment provides a stir-fry machine, which includes a fork device 100. The fork device 100 includes a frame and a fork body 1 for stir-frying food. The fork device 100 also includes a first drive mechanism 2, a first transmission mechanism, a second drive mechanism 4, and a second transmission mechanism. The first drive mechanism and the second drive mechanism are fixed to the frame. The first transmission mechanism and the second transmission mechanism are both connected to the fork body 1. The first drive mechanism 2 drives the fork body 1 to rotate around a first rotating shaft 101 extending horizontally, and the second transmission mechanism drives the fork body 1 to rotate around a second rotating shaft 102 extending vertically. By setting the first drive mechanism 2, the first transmission mechanism, the second drive mechanism 4, and the second transmission mechanism, the fork body 1 can be driven to rotate around the mutually perpendicular first rotating shaft 101 and second rotating shaft 102, so that the fork body 1 can better stir the food, improve the uniformity of stir-frying, and make the cooking effect of the food better.

[0063] The first drive mechanism 2 and the second drive mechanism 4 are respectively fixed on the frame. The first drive mechanism 2 drives the shift fork body 1 to rotate through the first transmission mechanism, and the second drive mechanism 4 drives the shift fork body 1 to rotate through the second transmission mechanism. The first transmission mechanism and the second transmission mechanism operate independently to avoid the second drive mechanism 4 being affected when the first drive mechanism and the first transmission mechanism are running, or the first drive mechanism 2 being affected when the second drive mechanism 4 and the second transmission mechanism are running. This can reduce the load on the first drive mechanism 2 and the second drive mechanism 4 during operation and improve the reliability of the shift fork device 100.

[0064] In this embodiment, as Figures 1-3 As shown, the outer contour of the fork body 1 is an arc shape adapted to the shape of the pot bottom, and the radial cross-sectional shape of the fork body 1 is triangular, with the apex of the triangle facing the first rotation axis 101. By setting the cross-sectional shape of the fork body 1 to a triangle, when the fork body 1 rotates around the first rotation axis 101, the food can be flipped under the action of the fork body 1, further improving the cooking effect of the food. Specifically, when the fork body 1 is stir-frying the food, when the fork body 1 rotates around the first rotation axis 101 and passes through the lowest point, the food can be flipped along the fork body 1.

[0065] Meanwhile, the outer contour of the fork body 1 matches the inner contour of the wok of the stir-fry machine, so that the fork body 1 can stir-fry the ingredients better.

[0066] Specifically in this embodiment, such as Figure 3 and Figure 4 As shown, the first transmission mechanism includes a first transmission shaft 32, a gear assembly 33, and a rack 34. The gear assembly 33 includes a first gear 331, a second gear 332, and a third gear 333. The first drive mechanism 2 is connected to one end of the first transmission shaft 32. The first gear 331 is located at the other end of the first transmission shaft 32 and is drively connected to the rack 34. The second gear 332 is coaxially arranged with the first rotating shaft 101, and the rack 34 is coaxially arranged with the second rotating shaft 102. The rack 34 is drively connected to the second gear 332 through the third gear 333. Through the action of the first transmission shaft 32, the gear assembly 33, and the rack 34, the shift fork body 1 rotates around the first rotating shaft 101 under the action of the first drive mechanism 2. Since the rack 34 and the second rotating shaft 102 are coaxially arranged, when the second drive mechanism 4 drives the shift fork body 1 to rotate around the second rotating shaft 102, the position of the rack 34 in the horizontal direction does not change, so that the rack 34 can maintain meshing with the first gear 331, and avoid the operation of the second drive mechanism 4 and the second transmission mechanism from affecting the first drive mechanism 2.

[0067] The first drive shaft 32 is a Hall effect shaft. A coupling 31 is provided between the first drive mechanism 2 and the first drive shaft 32 to improve the transmission effect between the first drive mechanism 2 and the first transmission mechanism.

[0068] At the same time, such as Figure 3 and Figure 5 As shown, the second transmission mechanism includes a turbine transmission assembly 51, a second transmission shaft 52, and a belt transmission assembly 53. The shift fork body 1 is connected to the belt transmission assembly 53, and the second drive mechanism 4 is connected to the turbine transmission assembly 51. The turbine transmission assembly 51 is connected to the belt transmission assembly 53 via the second transmission shaft 52, thereby driving the shift fork body 1 to rotate around the second rotating shaft 102. Through the action of the turbine transmission assembly 51, the second transmission shaft 52, and the belt transmission assembly 53, the shift fork body 1 rotates around the second rotating shaft 102 under the action of the second drive mechanism 4.

[0069] The belt drive assembly 53 includes a drive belt 532 and two drive pulleys 531. The second transmission mechanism directly drives the turbine drive assembly 51 to rotate. The turbine drive assembly 51 drives one of the drive pulleys 531 in the belt drive assembly 53 to rotate via the second transmission shaft 52, and transmits the rotation to the other drive pulley 531 connected to the shift fork body 1 via the drive belt 532, thereby driving the shift fork body 1 to rotate. The drive pulley 531 connected to the shift fork body 1 is coaxially arranged with the first rotating shaft 101. The rack 34 of the first transmission mechanism passes through the axis of this drive pulley 531 and moves vertically relative to this drive pulley 531.

[0070] Meanwhile, to facilitate the connection and installation of the first transmission assembly, the second transmission assembly, and the shift fork body 1, a rotating assembly is also provided in this embodiment. The rotating assembly is equivalent to a mounting base for the shift fork body 1. The belt transmission assembly 53 drives the rotating assembly to rotate, thereby driving the shift fork body 1 to rotate. The rack 34 is inserted vertically into the rotating assembly and fixed on the rotating assembly along the rotation direction of the transmission wheel 531 connected to the shift fork body 1. The third gear 333 is installed horizontally on the side wall of the rotating assembly, thereby fixing the shaft of the third gear 333.

[0071] Of course, in other embodiments, the second drive mechanism 4 can also drive the shift fork body 1 to rotate around the second rotating shaft 102 through other transmission structures in the prior art, which will not be described in detail here.

[0072] Specifically, the rack 34 in the first transmission assembly includes a first part 341 and a second part 342. The first part 341 has a first tooth 3411, which meshes with a first gear 331. The second part 342 is coaxially arranged with the first part 341 and rotatably connected to the first part 341. The first part 341 passes through the axis of the transmission wheel 531. The second part 342 is connected to the transmission wheel 531 in the direction of rotation and rotates synchronously. The second part 342 has a second tooth 3421, which meshes with a third gear 333. The third gear 333 meshes with the second gear 332. In other words, the first part 341 of the rack 34 meshes with the first gear 331 to make the rack 34 move in the vertical direction. The second part 342 of the rack 34 meshes with the third gear 333 through the second gear 332, thereby converting the vertical movement of the rack 34 into the rotation of the shift fork body 1. By setting the rack 34 as a first part 341 and a second part 342 that are rotatably connected, the fork body 1 does not interfere with each other when rotating around the first pivot 101 and the second pivot 102. That is, the fork body 1 can rotate around the first pivot 101 and the second pivot 102 at the same time, so that the fork body 1 can have a better stirring effect on the food.

[0073] Since the rack 34 is coaxially arranged with the second rotating shaft 102 and the second gear 332 is coaxially arranged with the first rotating shaft 101, the rack 34 needs to be connected to the second gear 332 through the third gear 333.

[0074] Of course, in other embodiments, the first drive mechanism 2 can also drive the shift fork body 1 to rotate around the first rotating shaft 101 through other transmission structures in the prior art, which will not be elaborated here.

[0075] In this embodiment, as Figures 4-6 As shown, the shift fork device 100 also includes a shift fork shaft 6 and a replacement mechanism 7. The shift fork shaft 6 is coaxially arranged with the first rotating shaft 101, and the shift fork shaft 6 is detachably connected to the shift fork body 1 through the replacement mechanism 7. The second gear 332 is arranged on the shift fork shaft 6. By setting the replacement mechanism 7, the shift fork body 1 can be replaced, thereby extending the service life of the cooking machine equipped with the shift fork device 100.

[0076] Specifically, there are two shift fork shafts 6, which are respectively located on both sides of the rack 34, and each shift fork shaft 6 is equipped with a second gear. The replacement device is located on one of the shift fork shafts 6. The replacement device includes a shift fork sleeve 9 and a pin. The outer circumference of the shift fork shaft 6 is provided with a groove, and the shift fork sleeve 9 is provided with a through hole. The engagement of the pin and the groove allows the shift fork sleeve 9 to be detachably connected to the shift fork, thereby realizing the detachability of the shift fork body 1.

[0077] Of course, in other embodiments, the detachable fork body 1 can also be achieved through other structures in the prior art, which will not be elaborated here.

[0078] In this embodiment, as Figure 1 As shown, the fork device 100 also includes a fork brush 8, which is disposed on the outer periphery of the fork body 1. The outer periphery of the fork body 1 has a mounting groove, and the fork brush 8 is partially embedded in the mounting groove. By providing the fork brush 8, the fork body 1 can not only be used for stir-frying food, but also for cleaning cookware.

[0079] Specifically, in this embodiment, both the first drive mechanism 2 and the second drive mechanism 4 are electric motors. Of course, in other embodiments, the first drive mechanism 2 and the second drive mechanism 4 can also be other power mechanisms in the prior art, which, together with the corresponding transmission components in the prior art, achieve the purpose of driving the shift fork body 1 to rotate, and will not be elaborated here.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
