Referring to fig. 1 to 3, a cooking machine 1 in an embodiment is used for cooking dishes to provide users with high-quality, convenient and safe meals. Cooking machine 1 includes platform 10 and platform elevating system 20, and platform 10 is used for placing the pan, and platform elevating system 20 is used for making platform 10 go up and down, is convenient for when the pan is placed to needs on the one hand, and platform 10 is close to the pan in order to support the pan, and on the other hand is convenient for when the action such as heeling or top is carried out to needs the pan, and proper interval has between pan and platform 10 is kept away from to platform 10 to avoid interfering. The cooking machine 1 has the characteristic of small volume, and can prevent the platform 10 from being blocked in the descending process.

The platform lifting mechanism 20 in one embodiment is used for lifting the platform 10, and can prevent the platform 10 from being stuck in the descending process, and the platform lifting mechanism 20 can be applied to the cooking machine 1 to reduce the volume of the cooking machine 1. The platform lifting mechanism 20 includes a base 200, a cam 300 and a follower 400, the cam 300 is rotatably disposed on the base 200, the follower 400 is movably disposed on the cam 300, and the rotating cam 300 can indirectly drive the platform 10 to descend through the follower 400.

Compared with the volume of the lifting mechanism for realizing lifting by using an electric cylinder, the volume of the lifting mechanism for realizing lifting by using a hydraulic cylinder or the volume of the lifting mechanism for realizing lifting by using a screw rod slide block, the volume of the lifting mechanism for realizing lifting by using the base 200, the cam 300 and the driven member 400 is relatively smaller, so that the volume of the cooking machine 1 can be reduced. The operating profile of the cam 300 is an incomplete operating profile, i.e. the operating profile of the cam 300 is not closed, and the volume of the cam 300 can be reduced by removing material from the non-closed portion of the operating profile, so as to further reduce the volume of the cooker 1.

It should be noted that, since the operating profile of the cam 300 is an incomplete operating profile, the cam 300 has only a near angle of repose, a push angle of motion, and a far angle of repose, and no return angle of motion. During the return stroke, the cam 300 rotates in the reverse direction.

Referring to fig. 4, further, the base 200 includes a bearing seat 210, the platform lifting mechanism 20 further includes a motor 510 and a driving shaft 520, the driving shaft 520 is disposed on the bearing seat 210 in a penetrating manner, the cam 300 is disposed on the driving shaft 520, and the motor 510 is used for driving the driving shaft 520 to rotate. During operation, the motor 510 drives the driving shaft 520 to rotate, the rotating driving shaft 520 drives the cam 300 to rotate, and the rotating cam 300 drives the platform 10 to ascend and descend. The lifting of the platform 10 can be achieved by changing the direction of rotation of the output shaft of the motor 510 to achieve the pushing and returning.

In this embodiment, when the output shaft of the motor 510 rotates counterclockwise, the cam 300 rotates counterclockwise, the platform 10 rises, and when the output shaft of the motor 510 rotates clockwise, the cam 300 rotates clockwise, and the platform 10 falls. Of course, in other embodiments, the platform 10 may be lowered when the output shaft of the motor 510 rotates counterclockwise, and the platform 10 may be raised when the output shaft of the motor 510 rotates clockwise.

Referring to fig. 5, in particular, the cam 300 is provided with a shaft passing hole 310, and the driving shaft 520 passes through the shaft passing hole 310, so as to realize the arrangement of the cam 300 on the driving shaft 520. The drive shaft 520 may rotate relative to the bearing housing 210, thereby allowing the cam 300 to rotate relative to the bearing housing 210. In this embodiment, the cam 300 is further provided with two lightening holes 320, so as to lighten the weight of the cam 300. Of course, in other embodiments, the number of lightening holes 320 may be adjusted to be at least one. Alternatively, the lightening holes 320 may be omitted.

Referring to fig. 4, in the present embodiment, the number of the bearing blocks 210 is two, the two bearing blocks 210 are oppositely disposed at an interval, and two ends of the driving shaft 520 respectively penetrate through the two bearing blocks 210. The output shaft of the motor 510 is coupled to the drive shaft 520 by a coupling 530. The platform elevating mechanism 20 further includes a base 511, and the motor 510 is disposed on the base 511. The motor 510 may be a controllable motor such as a stepping motor 510 or a servo motor 510 to control the rotation angle of the cam 300 according to the rotation angle of the output shaft of the motor 510, thereby controlling the elevation height of the platform 10.

Referring to fig. 5, the cam 300 includes a wheel body 301 and a limiting post 302, the limiting post 302 is disposed on an outer periphery of the wheel body 301, the base 200 includes a limiting block 220, the limiting block 220 is located in a rotation direction of the limiting post 302, and the limiting block 220 is used for abutting against the limiting post 302. The stop post 302 prevents over-travel rotation of the cam 300, which would otherwise cause failure of the platform lift mechanism 20 due to the incomplete operating profile of the cam 300. In this embodiment, when the cam 300 rotates counterclockwise to the limit position, the limit block 220 abuts against the limit post 302 to prevent the cam 300 from rotating counterclockwise. The stopper 220 is located between the two bearing seats 210 so as to abut against the stopper post 302.

Referring to fig. 1, the limiting block 220 includes a mounting plate 221 and an abutting plate 222 erected on the mounting plate 221, and the abutting plate 222 is used for abutting against the limiting post 302 to increase the abutting area. The mounting plate 221 may be provided with mounting holes, and the mounting plate 221 may be fixed to another member by a fastening member such as a bolt. In this embodiment, the base 200 further includes a bottom plate 230, and the bearing seat 210 and the limiting block 220 are disposed on the bottom plate 230.

Referring to fig. 6, the follower 400 includes a first connecting member 410 and a second connecting member 420, the first connecting member 410 is configured to be disposed on the platform 10, the first connecting member 410 can be driven by the cam 300 to move along an outer periphery of the cam 300, the second connecting member 420 is disposed on the cam 300, the second connecting member 420 can move relative to the cam 300, and a moving track of the second connecting member 420 is offset relative to an operating profile of the cam 300.

Referring to fig. 1, when the platform 10 ascends, the cam 300 rotates relative to the base 200, the rotating cam 300 drives the first connecting element 410 to move along the outer periphery of the cam 300, and the first connecting element 410 moving along the outer periphery of the cam 300 can drive the platform 10 to ascend because the first connecting element 410 is disposed on the platform 10. During the raising of the platform 10, the follower 400 moves from one end of the cam's operating profile to the other end of the cam's 300 operating profile.

When the platform 10 descends, the cam 300 rotates reversely with respect to the base 200, and the platform 10 descends under the action of gravity. During the lowering of the platform 10, the follower 400 moves from the other end of the operating profile of the cam 300 to one end of the operating profile of the cam 300. When the platform 10 is stuck or will be stuck, the cam 300 rotating in the opposite direction can drive the second connecting member 420 to move because the second connecting member 420 is disposed on the cam 300, the moving second connecting member 420 drives the first connecting member 410 to descend, and the first connecting member 410 is disposed on the platform 10, so that the platform 10 can be driven to descend, and the platform 10 is prevented from being stuck during descending. It should be noted that, since the operating profile of the cam 300 is an incomplete operating profile, when the second link 420 moves along the operating profile of the cam 300 to one end of the operating profile of the cam 300, the second link 420 needs to stop moving or move reversely. In this embodiment, the cam 300 is a disc-shaped cam 300, the cam 300 cannot rotate for a whole circle, and the rotation direction of the cam 300 needs to be changed when the motion of the platform 10 changes from ascending to descending or when the motion of the platform 10 changes from descending to ascending.

Referring to fig. 5 and 7, further, a groove 330 is formed on an end surface of the cam 300, the second connecting member 420 includes a boss 411, and the boss 411 extends into the groove 330. Taking this embodiment as an example, when the cam 300 rotates clockwise, the sidewall of the groove 330 abuts against the boss 411 to drive the second connecting member 420 to move relative to the cam 300, so as to prevent the platform 10 from being locked during the lifting process. It will be appreciated that during rotation of the cam 300, the boss 411 will move within the recess 330.

In this embodiment, the operating profile of the cam 300 is curved, the groove 330 is a curved groove 330, and the curved shape of the operating profile is similar to the curved shape of the groove 330 to facilitate movement of the second link 420 relative to the cam 300 along the operating profile of the cam 300. The boss 411 has a cylindrical shape. Of course, in other embodiments, the shape of the boss 421 can be flexibly adjusted according to actual conditions.

The first connector 410 includes a base 411 and a roller 412 rotatably disposed on the base 411, the roller 412 abuts against an outer circumference of the cam 300, the second connector 420 further includes a swing arm 422 swingably disposed on the base 411, and the boss 421 is disposed on the swing arm 422. The presence of the roller 412 may reduce the friction between the follower 400 and the cam 300, and the presence of the swing arm 422 may facilitate movement of the follower 400 relative to the cam 300 along the operating profile of the cam 300. When the cam 300 rotates, the swing arm 422 swings, and the roller 412 rolls on the outer periphery of the cam 300. It will be appreciated that the theoretical profile of the cam 300 is the path of movement of the center of the roller 412. In this embodiment, the number of rollers 412 is two to increase structural stability. Of course, in other embodiments, the number of rollers 412 may be adjusted to one or more.

In this embodiment, the boss 421 is fixedly connected to the swing arm 422, and the boss 421 slides in the groove 330. In another embodiment, the boss 421 may be hinged to the swing arm 422 to convert the manner in which the boss 421 moves within the groove 330 from sliding to rolling, which may serve to reduce wear. In another embodiment, the second connector 420 further includes a sleeve rotatably sleeved on the boss 421. The existence of the sleeve can change the moving mode of the boss 421 from sliding to rolling, thereby playing the role of reducing abrasion. Of course, in other embodiments, the moving manner of the boss 421 can be changed from sliding to rolling by other manners.

Specifically, in the present embodiment, the base 411 is provided with an installation groove 413, the roller 412 includes a shaft 414, a roller 415, a first locking member 416 and a second locking member 417, the shaft 414 is disposed in the installation groove 413, the roller 415 is rotatably disposed on the shaft 414, and the first locking member 416 and the second locking member 417 are respectively disposed at two opposite ends of the shaft 414 to prevent the shaft 414 from coming out of the installation groove 413. The presence of the mounting slot 413 facilitates the mounting of the roller 412, the detachable connection of the shaft 414 to the base 411 is achieved by securing the shaft 414 to the base 411 by means of the first and

second locking members

416, 417, and the presence of the roller 415 reduces the friction between the follower 400 and the cam 300. Of course, in other embodiments, the shaft 414 may be disposed on the base 411 in other manners.

In this embodiment, the first locking member 416 and the second locking member 417 are both nuts. Of course, in other embodiments, one of first locking member 416 and second locking member 417 may be a shoulder and the other may be a nut.

Referring to fig. 1, 8 and 9, in the cooker 1, the first connecting member 410 is disposed on the platform 10. The platform 10 includes a connection plate 110, and the first connection member 410 is disposed on the connection plate 110.

The platform 10 further comprises connector tiles 120, the connector tiles 120 being arranged on the guide sleeves 550, thereby enabling the arrangement of the platform 10 on the guide sleeves 550. The connection plate 120 is formed with a through hole through which the guide rod 540 is inserted. In this embodiment the number of connector tiles 120 is two.

Referring to fig. 10, the cooker 1 further includes a trigger 610, a first limit switch 620 and a second limit switch 630, the trigger 610 is disposed on the platform 10, the first limit switch 620 and the second limit switch 630 are disposed at intervals along the length direction of the guiding rod 540, and both the first limit switch 620 and the second limit switch 630 can be triggered by the trigger 610. When the first limit switch 620 or the second limit switch 630 is triggered, the motor 510 may be stopped so that the platform 10 stays at the corresponding position. Wherein, the trigger 610 can be disposed on the connection plate 120.

In this embodiment, the first limit switch 620 and the second limit switch 630 are distributed along the vertical direction, and the height of the first limit switch 620 is higher than that of the second limit switch 630. When the platform 10 moves to the top stroke end, the trigger 610 triggers the first limit switch 620, and the motor 510 stops rotating after the first limit switch 620 is triggered, so as to prevent the platform 10 from over-stroke movement. When the platform 10 moves to the down stroke end, the trigger 610 triggers the second limit switch 630, and the motor 510 stops rotating after the second limit switch 630 is triggered, so as to prevent the platform 10 from over-stroke movement.

It should be noted that, in the present embodiment, in a normal condition, after the second limit switch 630 is triggered, the motor 510 stops rotating, and the limit column 302 does not function. In an abnormal situation, the motor 510 fails to stop rotating after the second limit switch 630 is triggered, the cam continues to rotate counterclockwise, and the limit post 302 is in operation.

The presence of the first side plate 711 and the second side plate 712 ensures that the cleaning liquid is discharged in a specific direction, wherein the cleaning liquid may be clear water or a mixture of clear water and detergent.

Further, the cooking machine 1 further comprises a drainage plate 720, and the drainage plate 720 is disposed on the platform 10 and located between the first side plate 711 and the second side plate 712. The flow guide plate 720 is used to guide the cleaning solution so that the cleaning solution on the platform 10 can smoothly flow into the sink. In this embodiment, the flow guide plate 720 is disposed obliquely such that the height of the end of the flow guide plate 720 near the platform 10 is higher than the height of the end of the flow guide plate 720 far from the platform 10. Of course, in other embodiments, the thickness of the end of the flow guide plate 720 near the platform 10 may be thicker than the thickness of the end of the flow guide plate 720 remote from the platform 10.

The platform 10 includes a heating furnace 130, and when cooking, the pot can be placed on the heating furnace 130 to be heated, so as to cook delicious food. The heating furnace 130 may be an electromagnetic oven, an electric ceramic oven, an electric heating furnace, or a gas furnace. The heating furnace 130 is located between the first side plate 711 and the second side plate 712, and during cooking, the residue, seasonings, etc. may fall onto the heating furnace 130, which can clean the surface of the heating furnace 130.

The platform 10 further comprises a rack 140, and the heating furnace 130, the connecting plate 110, the connecting plate 120 and the drainage plate 720 are all arranged on the rack 140 to connect the components into a unified whole, so that the components can be lifted and lowered uniformly. In the present embodiment, the platform 140 is formed by splicing hollow aluminum profiles to reduce the overall weight of the platform 10.

The platform 10 further includes a panel 150, the panel 150 is disposed on the rack 140, a receiving hole is formed on the panel 150, and the heating furnace 130 is located in the receiving hole. However, the surface of the panel 150 is flush with the surface of the heating furnace 130 to improve the convenience of cleaning the stage 10. The panel 150 is hermetically connected to the heating furnace 130 and is subjected to a water-proof treatment to prevent leakage.

The specific working principle of the cooker 1 and the platform lifting mechanism 20 is as follows:

in heating, a pot is placed on the platform 10, and the food in the pot is heated by the heating furnace 130 to cook delicious food.

When the platform 10 is lifted, the motor 510 drives the cam 300 to rotate relative to the base 200, the roller 412 rolls relative to the cam 300 along the outer circumference of the cam 300, and the base 411 is disposed on the platform 10, so that the follower 400 can drive the platform 10 to lift. During the raising of the platform 10, the swing arm 422 swings with respect to the base 411, the roller 412 keeps in contact with the outer circumference of the cam 300 and rolls with respect to the cam 300, and the follower 400 moves from one end of the operating profile of the cam 300 to the other end of the operating profile of the cam 300.

When the platform 10 descends, the motor 510 drives the cam 300 to rotate reversely relative to the base 200, and the platform 10 descends under the action of gravity. During the lowering of the platform 10, the swing arm 422 swings reversely with respect to the base 411, the roller 412 keeps contact with the outer circumference of the cam 300 and rolls reversely with respect to the cam 300, and the follower 400 moves from the other end of the operating profile of the cam 300 to one end of the operating profile of the cam 300. When the platform 10 is stuck or will be stuck, the cam 300 rotating in the opposite direction can drive the second connecting member 420 to move because the second connecting member 420 is disposed on the cam 300, the moving second connecting member 420 drives the first connecting member 410 to descend, and the first connecting member 410 is disposed on the platform 10, so that the platform 10 can be driven to descend, and the platform 10 is prevented from being stuck during descending.

The lifting of the platform 10 can facilitate the pan to tilt or jolt, and meet the requirement of the pan for fast switching between the heating state and the action state in the process of frying dishes. The presence of the trigger 610, the first limit switch 620, and the second limit switch 630 may control the range of travel of the platform 10, preventing over-travel movement of the platform 10. On this basis, the rotation angle of the output shaft of the motor 510 can be controlled to stop the platform 10 at any position within the stroke range.

Compared with the volume of the lifting mechanism for realizing lifting by using an electric cylinder, the volume of the lifting mechanism for realizing lifting by using a hydraulic cylinder or the volume of the lifting mechanism for realizing lifting by using a screw rod slide block, the volume of the lifting mechanism for realizing lifting by using the base 200, the cam 300 and the driven member 400 is relatively smaller, so that the volume of the cooking machine 1 can be reduced. The working profile of the cam 300 is an incomplete working profile, that is, the working profile of the cam 300 is not closed, and the volume of the cam 300 can be reduced by removing the material at the position where the working profile is not closed, so that the requirement of miniaturization of the household appliance is met. In this embodiment, a portion of the material on the cam corresponding to the return portion is removed to reduce the volume of the cam. Of course, in other embodiments, the shape and size of the removed portion can be flexibly determined according to actual situations.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
