Description

Technical Field

[0001] The invention relates to the field of automatic cooking, and in particular to a material feeding switching structure and an automatic cooking machine. Background Art

[0002] The addition of seasonings is a key link in the cooking process. It is necessary to grasp the timing of addition and accurately control the amount to ensure that the cooked dishes taste delicious.

[0003] Most of the existing seasoning feeding devices use a plurality of relatively independent feeding tanks. When feeding is required, each feeding tank performs the feeding operation separately.

[0004] The above-mentioned seasoning delivery device has the following defects: each feeding tank needs to be provided with a driving device for driving the seasoning to be discharged, which increases the cost, occupies a large volume, and is difficult to set up the wiring. The above-mentioned defects also make it difficult to miniaturize the feeding device, and it is inconvenient to use it in the home. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art seasoning feeding device that is large in size and high in cost, and to provide a material feeding switching structure and an automatic cooking machine.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A material unloading switching structure comprises a driving mechanism, a selecting mechanism and a plurality of material unloading devices, wherein the selecting mechanism comprises an interference part and a rotating member, the rotating member is connected to the driving mechanism via a one-way transmission mechanism, the rotating member can rotate with the driving mechanism when the driving mechanism rotates forward, and release the transmission when the driving mechanism reverses, the rotating member can make the running path of the interference part pass through a plurality of selection positions when rotating with the driving mechanism, when the interference part is in the selection position, the material unloading device can be connected to the driving mechanism so that the driving mechanism drives the material unloading device by reverse rotation, the material unloading switching structure also comprises a limiting mechanism, a plurality of the limiting mechanisms are correspondingly arranged on one side of the selecting mechanism opposite to the forward rotation direction of the driving mechanism, the limiting mechanism can limit the interference part that passes through the limiting mechanism and reaches the selection position from reversing with the driving mechanism.

[0008] Such a structure can realize the structural reuse of the driving mechanism, which is responsible for driving the rotating member and the unloading device at the same time. Compared with the scheme of setting two driving mechanisms to control the rotating member and the unloading device respectively, it saves costs and simplifies the control logic, and can better realize production. In addition, through the limiting effect of the limiting mechanism, it can be avoided that the torque of the driving mechanism during reverse rotation acts on the rotating member, causing the rotating member to deviate from the selected position and cause the unintended termination of unloading, thereby improving the operational reliability.

[0009] Preferably, the limiting mechanism comprises an elastic member, the contour of the elastic member at least partially overlaps with the running path of the interference portion in the radial direction, and the elastic member can generate elastic deformation when contacting the interference portion and rebound and reset after passing over the interference portion.

[0010] After the interference portion passes over the elastic member and reaches the adjacent selection position, the elastic member can block the side of the interference portion opposite to the rotation direction thereof, thereby limiting the interference portion from reversing along with the driving mechanism.

[0011] Preferably, the end surface of the elastic member facing the running direction of the interference portion is a smooth transition end surface, and the end surface of the elastic member facing away from the running direction of the interference portion is a stop end surface.

[0012] The transition end surface can enable the interference portion to smoothly pass over the elastic portion, and the stop end surface can achieve reverse stop for the interference portion.

[0013] Preferably, the interference portion comprises a limiting member, which is a blocking piece extending radially outward from the rotating member, and the blocking piece is used to contact and pass over the limiting mechanism.

[0014] When the blocking piece passes over the elastic member, the elastic member will stop at a side of the blocking piece that is opposite to the rotation direction of the blocking piece, thereby limiting the reverse rotation of the blocking piece.

[0015] Preferably, the position limiting member further comprises a reinforcing rib connecting the blocking piece and the rotating member. The supporting effect of the reinforcing rib can improve the strength of the blocking piece and avoid deformation or breakage of the blocking piece.

[0016] Preferably, the feeding device comprises a main feeding mechanism and a clutch device, the clutch device is connected to the driving mechanism and the main feeding mechanism, and the interference part can contact and act on the clutch device during operation to switch from a disconnected state to a connected state.

[0017] Preferably, the clutch device comprises a reset member, and the reset member can apply an elastic biasing force to the clutch device to switch it toward the disconnected state.

[0018] Therefore, after the interference portion passes the selection position, the clutch device can be reset to the disconnected state, thereby preventing the driving mechanism from driving the main body unloading mechanism to operate together when driving the rotating member to perform the selection operation, thereby preventing the unloading from being caused by mistake.

[0019] Preferably, the clutch device includes a main gear connected to the driving mechanism, a driven gear axially offset from the main gear, a driven rod passing through the driven gear, the driven rod is connected to the main unloading mechanism, and the interference portion includes a protruding member provided on the axial side of the rotating member, the protruding member can contact and drive the driven rod to move axially so that the driven gear can switch from an axially offset state to an engaged state.

[0020] Preferably, the clutch device comprises a reset member, and the reset member comprises a spring sleeved on the driven rod, and the spring can apply an elastic biasing force to the driven rod to move the driven gear toward an axially misaligned state.

[0021] The present invention also provides an automatic cooking machine, comprising the material feeding switching structure as described above.

[0022] The positive and progressive effects of the present invention are:

[0023] The structure of the driving mechanism can be reused, which is responsible for driving the rotating member and the unloading device at the same time. Compared with the solution of setting two driving mechanisms to control the rotating member and the unloading device respectively, it saves costs and simplifies the control logic, and can better realize production. In addition, through the limiting effect of the limiting mechanism, it can be avoided that the torque of the driving mechanism when reversing acts on the rotating member, causing the rotating member to deviate from the selected position and causing the unintended termination of unloading, thereby improving the operational reliability.

[0049] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0050] like Figure 1 As shown, a material unloading switching structure includes a driving mechanism 100, a selection mechanism 200 and a plurality of material unloading devices 300.

[0051] The driving mechanism 100 is a motor, and the selection mechanism 200 includes an interference portion 220 and a rotating member, which is annular and connected to the driving mechanism 100 through a one-way transmission mechanism. Specifically, the one-way transmission mechanism is a ratchet pawl structure, and the ratchet and pawl are connected to the rotating member and the driving mechanism 100 respectively, and the pawl is engaged in the teeth gap of the ratchet. When the driving mechanism 100 rotates forward, the pawl can be stuck in the teeth gap of the ratchet so that the ratchet pawl is locked with each other, so that the rotating member can rotate with the driving mechanism 100 when it rotates forward. When the driving mechanism 100 rotates in the reverse direction, the pawl passes over the back of the teeth on the ratchet, and the rotating member will not rotate with the driving mechanism 100 at this time, thereby realizing the one-way drive of the rotating member. Since it is a common technology to realize one-way rotation through a ratchet pawl structure, the drawings of the ratchet pawl structure are not disclosed here.

[0052] Combination Figure 1 and Figure 2When the rotating member rotates with the driving mechanism 100, the running path of the interference portion 220 can correspond to passing through multiple selection positions 500. When the interference portion 220 is in the selection position 500, the unloading device 300 can be connected with the driving mechanism 100 so that the driving mechanism 100 can drive the unloading device 300 to operate by reverse rotation.

[0053] Such a structure can realize structural reuse of the driving mechanism 100, which is responsible for driving both the rotating member 210 and the unloading device 300. Compared with the solution of setting two driving mechanisms 100 to control the rotating member 210 and the unloading device 300 respectively, it saves costs and simplifies control logic, and can better realize production.

[0054] However, this driving scheme has the following problems: although the ratchet pawl structure can release its transmission connection with the rotating member when the driving mechanism 100 reverses, the ratchet pawl structure will still contact and rub against each other during the reverse operation of the driving mechanism 100, thereby applying a reverse torque to the rotating member. Under the action of this torque, the rotating member may produce a slight rotation and deviate from the preset selection position 500, causing the unloading device 300 to no longer be in transmission connection with the driving mechanism 100, resulting in unloading failure. In order to avoid the occurrence of the above problems, the unloading switching structure also includes a limiting mechanism 400, the number of which is consistent with the number of the selection positions 500, and a plurality of limiting mechanisms 400 are correspondingly arranged on the side of the selection mechanism opposite to the forward direction of the driving mechanism 100, and the limiting mechanism 400 can limit the interference portion 220 that crosses the limiting mechanism 400 and reaches the selection position 500 from reversing with the driving mechanism 100.

[0055] The limiting function of the limiting mechanism 400 can prevent the torque of the driving mechanism 100 from acting on the rotating member during reverse rotation, causing the rotating member to deviate from the selected position 500 and result in unexpected termination of material unloading, thereby improving operational reliability.

[0056] In this embodiment, the limiting mechanism 400 includes an elastic member 410, the contour of which at least partially overlaps with the running path of the interference portion 220 in the radial direction, so that when the interference portion 220 runs along its running path, it can contact the elastic member 410. The elastic member 410 can generate elastic deformation when contacting the interference portion 220 and rebound to its original position after the interference portion 220 passes over it. After the interference portion 220 passes over the elastic member 410 and reaches the adjacent selection position 500, the elastic member 410 can block the side of the interference portion 220 that is opposite to its rotation direction, thereby limiting the interference portion 220 from reversing with the driving mechanism 100.

[0057] In order to allow the interference portion 220 to smoothly pass over the elastic portion, the end face of the elastic member 410 facing the running direction of the interference portion 220 is a smooth transition end face, which can be a curved surface or a plane with a small angle (0-15°) relative to the circumferential surface of the rotating portion. In order to stop the interference portion 220, the end face of the elastic member 410 facing away from the running direction of the interference portion 220 is a stop end face. The stop end face can be an end face perpendicular to the circumferential surface of the rotating portion, or an end face with a reverse bevel relative to the circumferential surface of the rotating portion.

[0058] Combination Figure 3 Specifically, in the present embodiment, the elastic member 410 is an L-shaped spring, including a vertical portion 411 perpendicular to the circumferential surface of the rotating portion and a horizontal portion 412 connected to the vertical portion 411, the free end of the horizontal portion 412 faces the side opposite to the running direction of the interference portion 220, the outer peripheral surface of the horizontal portion 412 constitutes the transition end surface, and the free end surface of the horizontal portion 412 opposite to the running direction of the interference portion 220 constitutes the stop end surface.

[0059] Combination Figure 1 and Figure 2 In the present embodiment, the interference portion 220 includes a limit member 221 arranged on the circumferential side of the rotating member, and the limit member 221 has a baffle 222 extending radially outward from the rotating member. The baffle 222 is arranged in the vertical direction for contacting and passing over the elastic member 410. When the baffle 222 passes over the elastic member 410, the elastic member 410 will stop on the side of the baffle 222 opposite to its rotation direction, thereby limiting the reversal of the baffle 222.

[0060] Since the baffle 222 is arranged vertically and extends radially outward from the rotating member, it is easy to be deformed or even broken by the lateral force during rotation. To avoid the above problem, the stopper 221 also includes a reinforcing rib 223 connecting the baffle 222 and the outer peripheral surface of the rotating member. Specifically, the reinforcing rib 223 is a triangular reinforcing rib plate arranged on both sides of the stopper 221. The strength of the baffle 222 can be improved by the supporting effect of the reinforcing rib 223, so as to avoid the problem of deformation or breakage of the baffle 222. To avoid the reinforcing rib 223 interfering with the normal operation of the baffle 222, the triangular reinforcing rib plate is preferably arranged horizontally at the bottom of the baffle 222.

[0061] Combination Figure 4 In this embodiment, the unloading device 300 includes a main unloading mechanism 310 and a clutch device 320 for connecting the driving mechanism 100 and the main unloading mechanism 310. The interference portion 220 can act on the clutch device 320 during operation to switch the clutch device 320 from a disconnected state to a connected state.

[0062] Specifically in this embodiment, the clutch device 320 further includes a reset member 321, which can apply an elastic biasing force to the clutch device 320 to switch it to the disconnected state. Therefore, after the interference portion 220 passes the selection position 500, the clutch device 320 can be reset to the disconnected state, thereby preventing the driving mechanism 100 from driving the main body unloading mechanism 310 to operate together when the driving rotating member performs the selection operation, thereby preventing the unloading from being caused by mistake.

[0063] In this embodiment, the specific structure of the clutch device 320 is as follows: it includes a main gear 322 connected to the driving mechanism 100, a driven gear 323 axially staggered with the main gear 322, and a transmission rod 324 connecting the driven gear 323 and the main unloading mechanism 310. The interference portion 220 also includes a protrusion provided on the axial side of the rotating portion, which can contact and drive the transmission rod 324 to move axially, thereby switching the driven gear 323 from a non-transmission state axially staggered with the main gear 322 to a transmission state meshing with the main gear 322. In this way, the connection and disconnection between the main unloading mechanism 310 and the driving mechanism 100 are realized.

[0064] In this embodiment, the reset member 321 in the clutch device 320 is a spring sleeved on the transmission rod 324, which can apply a biasing force to the transmission rod 324 to make it move axially upward, so that after the protrusion passes over the transmission rod 324, the transmission rod 324 can rebound and reset through the spring, so that the clutch device 320 is disconnected from the drive mechanism 100 again.

[0065] The present invention also provides an automatic cooking machine, comprising the above-mentioned material switching structure, which also has the advantages of simple structure, simple control logic and reliable use.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
