Description

Technical Field

[0001] The invention relates to the technical field of kitchen automation equipment, and in particular to a small-volume single-drive central axis integrated automatic cooking and warming machine. Background Art

[0002] A cooking machine is a device that heats the ingredients in a pot through microcomputer control to cook food. The development of cooking machines eliminates the hidden dangers to lung health caused by long-term exposure to oil fumes, and saves people's cooking time, allowing people to have more time to enjoy home life or devote more time to other work.

[0003] However, it is difficult for traditional cooking machines to achieve compatibility between the feeding function and the size. Cooking machines with smaller size often require manual feeding of ingredients into the pot, which is cumbersome to operate. Cooking machines with feeding function have complex structures. During the operation of the cooking machine, multiple driving components need to work simultaneously to realize the cooking and feeding functions. Such cooking machines are often large in size, making it difficult to adapt to smaller residential areas, and are costly, making it difficult to improve the market competitiveness of the equipment. Summary of the invention

[0004] Based on this, it is necessary to provide a low-cost, small-volume single-drive central axis integrated automatic cooking and insulation machine to address the technical problems that small-volume cooking machines require manual feeding and large-volume cooking machines have complex structures and high costs.

The card is snap-connected or magnetically connected to the bottom of the food grid, and a plurality of abutment rods are provided at the bottom of the lifting transmission member. When the lifting transmission member is lowered by the action of the screw rod, the card moves under the push of the abutment rod to drive the bottom plate to open, so that the food falls from the food grid into the boiler mechanism.

[0012] In one of the embodiments, the food distribution unit is located above the cooking execution unit, and the food distribution unit includes a central axis inserted in the middle of the food grid and a food distribution turntable sleeved on the central axis and rotatable relative to the food grid. The food distribution turntable is located at the bottom of the food grid and is used to receive the food contained in the food grid. A drop hole is opened on the food distribution turntable; when the food grid rotates relative to the food distribution turntable, the food on the food distribution turntable is scraped and the food is unloaded from the drop hole into the boiler mechanism.

The lifting transmission member includes a nut and a power disk which are sequentially sleeved on the screw. The nut is threadedly connected to the screw. At least two guide rods extending along the thickness direction of the power disk are provided on the side of the power disk facing away from the nut. At least one guide rod passes through the turntable and is radially fixed to the turntable. A pot body fixing frame is provided at the end of the guide rod for limiting the position of the boiler mechanism. The power disk is used to drive the guide rod to rise and fall under the push or pull action of the nut, and the guide rod rotates under the drive of the turntable.

[0014] In one of the embodiments, the lifting transmission member also includes a pair of pulleys arranged on both sides of the nut, the two pulleys are fixedly connected to the power disk respectively, and the outer surface of the nut is provided with a flange portion that matches the wheel groove of the pulley.

[0015] In one of the embodiments, the single-rod drive unit also includes a motor mounting plate and an anti-rotation block. The motor is fixedly mounted on the motor mounting plate, and the output end of the motor passes through the motor mounting plate and is connected to the screw gear. The anti-rotation block is sleeved on the screw and is fixedly connected to the motor mounting plate and the nut respectively. The anti-rotation block is used to limit the circumferential movement of the nut. The screw is a hollow structure, and the inner cavity of the screw is passed through a center rod fixedly connected to the motor mounting plate.

[0016] In one embodiment, a single-rod driving unit is located above the food distribution unit, the top of the central axis is connected to the end of the central rod, a protrusion is provided on the top of the food distribution turntable, and a push rod that rotates synchronously with the turntable is provided on the turntable. The push rod is used to push the protrusion to rotate so that the food distribution turntable rotates relative to the food grid, so that the food is unloaded into the boiler mechanism through the drop hole.

[0017] In one of the embodiments, the cooking and keeping warm machine also includes a cleaning component, which includes a water injection pipe and a water suction pipe extending to the bottom of the boiler mechanism, the water injection pipe and the water suction pipe are respectively fixed in the center rod, and the water injection pipe is used to connect cleaning water to the boiler mechanism. When the guide rod drives the boiler mechanism to perform a compound motion of rotation and lifting, the cleaning water is mixed with the inner wall of the boiler mechanism or the material in the boiler mechanism and cleaned, and then the water suction pipe sucks away the cleaning waste water in the boiler mechanism.

[0018] In one embodiment, the cleaning assembly also includes a pot brush and a detergent tube. The detergent tube is fixed in the center rod, and the pot brush is installed on the pot body fixing frame. When the guide rod drives the boiler mechanism to perform a compound motion of rotation and lifting, the boiler mechanism and the pot brush move relative to each other so that the pot brush penetrates into the boiler mechanism, so that the pot brush rinses the boiler mechanism. The detergent tube is used to connect the detergent to the boiler mechanism.

[0019] In one of the embodiments, the cooking and keeping warm machine also includes a sieve for holding food materials, and the sieve is fixedly mounted on a pot body fixing frame. After the boiler mechanism heats the water injected through the water injection pipe, the pot body fixing frame drives the sieve to rotate and descend until the food materials come into contact with the hot water under the drive of the motor and the transmission of various components, so as to blanch the food materials; the pot body fixing frame drives the sieve to leave the boiler mechanism, and after the hot waste water in the boiler mechanism is sucked away through the water suction pipe and clean water is injected into the boiler mechanism, the pot body fixing frame drives the sieve to rotate and descend until the food materials come into contact with the cold water, so as to cool down the blanched food materials.

[0020] The single-drive central axis integrated automatic cooking and warming machine of the present invention can drive the spatula assembly to move through the cooperation of the lifting transmission member and the turntable, thereby stir-frying the ingredients in the boiler mechanism to avoid the problem of sticking to the pot, and when the lifting transmission member is close to the ingredient distribution unit, it can drive the ingredient grid to rotate or lift some components on the ingredient grid to open the drop hole, and then the ingredients in the ingredient grid can be unloaded into the cooking execution unit. In this way, the ingredients can be stir-fried and put into the boiler assembly by one motor, and the cooking operation can be automatically unloaded, which reduces the manual operation links. In addition, when a single motor is used for driving, the structure of the cooking and warming machine is simpler, and fewer components are required to complete the functions of the equipment. , the cost is reduced, and the overall size of the stir-frying and warming machine is reduced, which is convenient for users to plan the placement of the equipment in the kitchen; furthermore, the cooking execution unit can adopt a conventional split boiler or an integrated boiler, which improves the versatility of the automatic stir-frying and warming machine with existing kitchen utensils, and there is no need to purchase an additional boiler, which further reduces the user's cooking cost; in addition, the various components of the equipment are covered by the outer shell of the stir-frying and warming machine, and the oil smoke generated during the cooking process is only discharged through the holes on the top of the cover, which is convenient for the oil smoke to be discharged to the outside through the external smoke exhaust fan, avoiding the problem of increased kitchen cleaning workload caused by the use of an open design, oil smoke diffused in the kitchen or grease splashed on the kitchen countertop, reducing the user's labor input, and is conducive to improving the market competitiveness of the product.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figure 1 and Figure 2The present invention provides a low-cost, small-volume, single-drive central axis integrated automatic cooking and heat preservation machine 10, which includes a single-set rod drive unit 100, a cooking execution unit 200, and a food distribution unit 300. The single-set rod drive unit 100 is used to provide power for the relative movement of various components in the cooking and heat preservation machine. The boiler mechanism 210 of the cooking execution unit 200 is used to receive the food to be cooked and heat or perform other operations on the food. The food distribution unit 300 is used to automatically put the prepared food into the cooking execution unit 200 to realize the feeding of the cooking operation. In the present invention, the food distribution unit 300 is always located above the cooking execution unit 200, that is, the food falls into the boiler mechanism 210 by its own weight, and the single-set rod drive unit 100 is located on the top of the food distribution unit 300. In other words, the cooking and heat preservation machine of the present invention adopts a drive top structure.

[0038] Please combine Figure 1 and Figure 2 The single-rod driving unit 100 includes a motor 110, a screw 120 driven by the motor 110 and rotating synchronously with the motor 110, a lifting transmission member 130 sleeved on the screw 120 and performing lifting movement relative to the screw 120 when the screw 120 rotates, and a guide rod penetrating the lifting transmission member 130 and directly or indirectly fixed to the motor 110, that is, the guide rod is mounted on the housing of the motor 110 or fixedly connected to a bracket supporting the motor 110, for example, fixedly connected to the motor mounting plate 150. During the operation of the cooking and heat preservation machine, the position of the guide rod does not change and does not rotate. The cooking execution unit 200 includes a boiler mechanism 210 for receiving and heating food materials and a spatula assembly 220 mounted at the end of the guide rod and cooperating with the screw 120, and used to move relative to the boiler mechanism 210 under the drive of the screw 120 to turn over the food materials in the boiler mechanism 210. The boiler mechanism 210 includes a pot body 211 and a furnace 212. The furnace 212 is arranged below the pot body 211 and heats the food in the pot body 211. Of course, the boiler mechanism 210 may also only include a self-heating pot, such as an electric pot. When the lifting transmission member 130 drives the spatula assembly 220 to move, the spatula assembly 220 moves relative to the boiler mechanism 210 to turn over the food in the boiler mechanism 210, so that the food is evenly heated and the problem of food sticking to the bottom of the pot is avoided.

[0039] Further, please combine Figure 2 and Figure 3The spatula assembly 220 includes a cover shell 221 which is fixedly connected to the end of the guide rod and has through-connected top and bottom surfaces. A gear 222 fixedly connected to the screw rod 120 and a rack structure 223 slidably arranged on the inner surface of the cover shell 221 and meshingly connected to the gear 222 are provided in the cover shell 221. One end of the rack structure 223 is hingedly connected to a connecting rod 224, and a pendulum block 225 pivotally connected to a side surface of the cover shell 221 is provided at the free end of the connecting rod 224. One end of the pendulum block 225 is rotatably matched with the connecting rod 224 through a rotating shaft, and a shovel 226 is installed at the other end of the pendulum block 225. Preferably, one end of the pendulum block 225 adjacent to the connecting rod 224 is in a cam structure, and the connecting rod 224 rotates in cooperation with the convex portion of the cam structure. In this way, when the screw 120 rotates under the drive of the motor 110 and drives the gear 222 to rotate synchronously, the rack structure 223 reciprocates in the cover shell 221 under the action of the gear 222, so that the connecting rod 224 swings in a vertical plane. In this way, the pendulum block 225 swings under the eccentric force of the connecting rod 224 and the constraint of the wall of the cover shell 221, so that the pendulum block 225 drives the shovel 226 to swing relative to the boiler mechanism 210 and flip the food contained in the boiler mechanism 210, thereby achieving the purpose of stir-frying the food.

[0040] See also Figure 4 In another embodiment, the spatula assembly 220 and Figure 3 The structures of the spatula assembly 220 shown are basically the same. The difference between the two is that the rack structure 223 is replaced by a slider 227 which is hinged to the connecting rod 224 and can slide in the cover shell 221. A through groove 2271 is provided at the top of the slider 227, and a guide groove 2272 extending perpendicular to the swing direction of the pendulum block 225 is provided at the bottom of the through groove 2271. The gear 222 is replaced by a transmission bar 228 which is fixedly connected to the screw rod 120 and rotates with the screw rod 120. A limiting rod inserted into the guide groove 2272 is provided at the bottom of the transmission bar 228. When the transmission bar 228 rotates driven by the screw rod 120, the limiting rod slides along the guide groove 2272 under the constraint of the guide groove 2272. In this case, the slider 227 is subjected to uneven force and thus swings in the horizontal plane, thereby driving the connecting rod 224, the pendulum block 225 and the spatula 226 to swing in sequence, thereby achieving the purpose of stir-frying the ingredients.

[0041] See also Figure 5 In another embodiment, the spatula assembly 220 includes a rotating spatula 229 fixedly connected to the end of the screw 120. When the screw 120 rotates under the drive of the motor 110, the rotating spatula 229 is driven to rotate synchronously to turn over the food contained in the boiler mechanism 210. Specifically, when the screw 120 rotates, the rotating spatula 229 is driven by the screw 120 to rotate to stir and turn over the food in the pan body 211.

[0042] Please combine Figure 2 Figure 6The single-set rod driving unit 100 is located above the food distribution unit 300. The food distribution grid 320 includes a bottom plate 324 that opens and closes in a vertical plane to form a material drop hole 331 when subjected to force. A card 325 is provided at the movable end of the bottom plate 324. The card 325 is snap-connected or magnetically connected to the bottom of the food distribution grid 320. A plurality of abutment rods are provided at the bottom of the lifting transmission member 130. When the lifting transmission member 130 is lowered by the screw 120, the card 325 moves under the push of the abutment rod to drive the bottom plate 324 to open, so that the food falls from the food distribution grid 320 into the boiler mechanism 210, thereby achieving the purpose of distributing food. In this embodiment, the lifting transmission member 130 includes a plate member arranged on the top of the screw 120. During the rotation of the screw 120, the card 325 opens and closes to discharge the material under the drive of the plate member.

[0043] See also Figure 7 In another embodiment, the single-rod driving unit further includes a turntable 140 which is sleeved on the screw 120 and movably connected to the lifting transmission member 130 and is used to drive the lifting transmission member 130 to rotate under the drive of the screw 120, and the turntable 140 is a flat long strip structure. A first gear 111 is provided at the output end of the motor 110, and a second gear 121 meshing with the first gear 111 is installed at the bottom of the screw 120. In this way, when the motor 110 is working, the screw 120 rotates under the drive action of the first gear 111 and the second gear 121, and drives the turntable 140 to rotate, thereby providing a torsional force for the lifting transmission member 130 to rotate; when the lifting transmission member 130 moves relative to the screw 120 and appears to be a lifting motion to the outside, the lifting transmission member 130 actually performs a rotation and lifting compound motion, that is, a spiral motion, thereby causing other objects connected to the lifting transmission member 130 to perform a spiral motion.

[0044] For further information, see Figure 8The lifting transmission member 130 includes a nut 131 and a power disk 132 which are sequentially sleeved on the screw rod 120, the nut 131 is threadedly connected to the screw rod 120, the power disk 132 is only sleeved on the outer surface of the screw rod 120 and can move relative to the screw rod 120, and at least two guide rods 133 extending along the thickness direction of the power disk 132 are provided on the side of the power disk 132 facing away from the nut 131, that is, the guide rods 133 are arranged in parallel with the screw rod 120, at least one guide rod 133 passes through the turntable 140 and is radially fixed to the turntable 140, and a pot body fixing frame 134 for limiting the position of the boiler mechanism 210 is provided at the end of the guide rod 133, and a clamping opening for quickly embedding the boiler mechanism 210 is provided on the pot body fixing frame 134, and the power disk 132 is used to drive the guide rod 133 to rise and fall under the pushing or pulling action of the nut 131, and the guide rod 133 rotates under the drive of the turntable 140. Specifically, a circular hole is provided on the turntable 140 for the guide rod 133 to pass through. When the guide rod 133 passes through the circular hole, the guide rod 133 can only move along the depth direction of the circular hole under the constraint of the inner surface of the circular hole, and cannot move along the radial direction of the circular hole. In other words, the guide rod 133 can only be raised and lowered relative to the turntable 140, but cannot be rotated relative to the turntable 140. In this way, in the process of the turntable 140 driving the guide rod 133 to rotate, there is no relative displacement between the two in the horizontal plane, and the rotation amount of the guide rod 133 is determined by the rotation amount of the turntable 140, thereby improving the reliability of the rotation of the guide rod 133.

[0045] It should be noted that in order to ensure that the power disk 132 can not only perform lifting motion under the drive of the nut 131, but also rotate relative to the screw 120 under the drive of the turntable 140 and the guide rod 133, it is necessary to set the nut 131 and the power disk 132 independently, so that the power disk 132 can also rotate relative to the nut 131 when performing lifting motion transmission with the nut 131. Figure 8 and Fig. 9 In one embodiment, the lifting transmission member 130 also includes a pair of pulleys 135 arranged on both sides of the nut 131, and the two pulleys 135 are fixedly connected to the power disk 132 respectively. The outer surface of the nut 131 is provided with a flange portion 131a that matches the groove of the pulley 135. In this way, the power disk 132 is positioned with the nut 131 in the axial direction of the screw rod 120 through the concave-convex match between the pulley 135 and the outer surface of the nut 131. When the slide groove 135a of the pulley 135 moves along the flange portion 131a of the nut 131, the power disk 132 rotates relative to the nut 131.

[0046] Furthermore, in order to improve the reliability of the lifting and lowering movement of the nut 131, in one embodiment, the single-rod drive unit 100 also includes a motor mounting plate 150 and an anti-rotation block 160. The motor 110 is fixedly mounted on the motor mounting plate 150, and the output end of the motor 110 passes through the motor mounting plate 150 and is gear-connected to the screw 120. The anti-rotation block 160 is sleeved on the screw 120 and is respectively fixedly connected to the motor mounting plate 150 and the nut 131. The anti-rotation block 160 is used to limit the circumferential movement of the nut 131. The screw 120 is a hollow structure, and the inner cavity of the screw 120 is passed through a center rod 170 fixedly connected to the motor mounting plate 150. Preferably, the anti-rotation block 160 includes a limit plate fixedly connected to the nut 131 and two telescopic rods arranged at both ends of the limit plate and respectively fixedly connected to the motor mounting plate 150. The telescopic rods are fixedly connected to the motor mounting plate 150 to limit the circumferential displacement of the limit plate and the nut 131, that is, to prevent the nut 131 from rotating relative to the screw rod 120, to avoid the "slip" problem during the rotation of the screw rod 120, so as to facilitate the precise adjustment of the relative displacement between the nut 131 and the screw rod 120 by controlling the speed of the motor 110 and other parameters. When the nut 131 is raised or lowered relative to the screw rod 120, the telescopic rods are extended or shortened relative to the motor mounting plate 150 to adapt to the height of the nut 131.

[0047] Please combine Fig.10 as well as Fig.11 The food distribution unit 300 includes a food grid 320 for containing food, and an openable and closable material drop hole 331 is provided on the food grid 320. When the food grid 320 is subjected to the rotation or lifting action of the lifting transmission member 130, the material drop hole 331 opens and closes, so that the food enters the boiler mechanism 210 through the material drop hole 331. Specifically, the food distribution unit 300 is located above the cooking execution unit 200, and the food distribution unit 300 includes a central axis 310 inserted in the middle of the food grid 320 and a food distribution turntable 330 sleeved on the central axis 310 and rotatable relative to the food grid 320. The food grid 320 includes a plurality of compartments 321 evenly distributed on the circumference of the central axis 310, and the top and bottom of each compartment 321 are connected. The food distribution turntable 330 is located at the bottom of the food grid 320 and is used to receive the food contained in the food grid 320. According to cooking needs, the user can put different food raw materials or additives in different compartments 321. The food distribution turntable 330 is provided with a drop hole 331; when the food grid 320 rotates relative to the food distribution turntable 330, the food on the food distribution turntable 330 is scraped and the food is unloaded from the drop hole 331 into the boiler mechanism 210, thereby realizing the delivery of food into the boiler mechanism 210.

[0048] The top of the food distribution grid 320 is provided with a cover with a central circular hole (not shown in the figure), and the middle of the central axis 310 is provided with a through hole extending along the axial direction of the central axis 310, and the through hole is respectively connected to the bottom of the food distribution turntable 330 and the top of the cover, and together form a smoke exhaust channel. In this way, the cooking and warming machine only needs a single driving mechanism to achieve the turning and feeding of the food, and the entire cooking operation is limited to the inner cavity of the shell 400. The oil smoke generated during the cooking process can only be discharged through the central circular hole on the top of the cover, avoiding the problem of oil smoke diffusion and grease splashing during the cooking process, reducing the workload of cleaning the kitchen later, and the oil smoke can be directly discharged to the outside through the smoke extractor, reducing the damage of the diffused oil smoke to the user's respiratory system.

[0049] Please combine Fig.10 , Fig.11 Fig.12 The top of the central shaft 310 is connected to the end of the central rod 170, a convex block 332 is provided on the top of the food distribution turntable 330 or the top of the pot body fixing frame 134, and a push rod 141 is provided on the turntable 140 to rotate synchronously with the turntable 140. The push rod 141 is used to push the convex block 332 to rotate so that the food distribution turntable 330 rotates relative to the food grid 320, so that the food is discharged into the pot body 211 through the drop hole 331. Of course, in this embodiment, a driving motor can also be used to drive the central shaft 310 to rotate to provide power for the rotation of the food distribution turntable 330.

[0050] It should be further explained that the cooking insulation machine of the present invention also includes a plurality of accessories that can be disassembled and used interchangeably with the food dispensing unit 300, that is, when using the food dispensing unit 300, such accessories need to be removed, and when using such accessories, the food dispensing unit 300 needs to be removed from the outer shell 400.

[0051] See also Fig.13In one embodiment, the cooking and heat preservation machine further includes a cleaning component 500, which includes a water injection pipe 510 and a water suction pipe 520 extending to the bottom of the boiler mechanism 210. The water injection pipe 510 and the water suction pipe 520 are respectively fixed in the center rod 170. The water injection pipe 510 is used to connect the cleaning water to the boiler mechanism 210. After the guide rod 133 drives the boiler mechanism 210 to rotate and lift the composite movement, so that the cleaning water mixes with the inner wall of the boiler mechanism 210 or with the materials in the boiler mechanism 210 and washes, the water suction pipe 520 sucks away the cleaning waste water in the boiler mechanism 210. In actual use, the cleaning component 500 can be used for washing work before the cooking operation begins, such as washing rice. Specifically, the water injection pipe 510 and the water suction pipe 520 are respectively fixed in the center rod 170. When the rice grains to be washed are loaded into the boiler mechanism 210, the external controller turns on the water injection pump and adds clean water to the boiler mechanism 210 through the water injection pipe 510. Then, the pot body fixing frame 134 drives the boiler mechanism 210 to rotate and lift under the action of the guide rod 133, so that the rice grains in the boiler mechanism 210 are fully in contact with the clean water, and friction is generated between the rice grains and between the rice grains and the inner wall of the boiler mechanism 210, so that the dust and other impurities on the rice grains are washed into the water, and the rice grains are washed. After the rice grains are washed, the motor 110 is started to work, so that the pot body fixing frame 134 drives the boiler mechanism 210 to rise under the action of the guide rod 133, so that the input end of the water suction pipe 520 reaches the bottom of the boiler mechanism 210, and then the external controller starts the water suction pump to suck and discharge the cleaning waste water in the boiler mechanism 210 through the water suction pipe 520.

[0052] For further information, see Fig.14 The cleaning assembly 500 also includes a pot brush 530 and a detergent tube 540. The detergent tube 540 is fixed in the center rod 170. The pot brush 530 is installed on the pot body fixing frame 134. When the guide rod 133 drives the boiler mechanism 210 to rotate and lift the boiler mechanism 210, the boiler mechanism 210 and the pot brush 530 move relative to each other so that the pot brush 530 penetrates into the boiler mechanism 210, so that the pot brush 530 rinses the boiler mechanism 210. The detergent tube 540 is used to connect the detergent to the boiler mechanism 210. Specifically, the pot brush 530 includes a brush head and a brush handle connected to the brush head, the brush handle is a hollow structure and communicated with the bottom of the brush head, the water injection pipe 510, the water suction pipe 520 and the detergent pipe 540 are respectively passed through the brush handle, and among the three pipes, at least the water suction pipe 520 extends out of the bottom of the brush head, so that when the height of the brush head is adjusted, the water suction pipe 520 can contact the bottom of the boiler mechanism 210 to suck away the water in the boiler mechanism 210. In this case, the cleaning assembly 500 is used to wash the dirt or food residue in the boiler mechanism 210.

[0053] Specifically, the water injection pipe 510, the water suction pipe 520 and the detergent pipe 540 are respectively fixed in the central rod 170, and the pot brush 530 is installed on the pot body fixing frame 134. In the process of cleaning the boiler mechanism 210, the external controller first controls the water injection pump to inject a proper amount of clean water into the boiler mechanism 210 through the water injection pipe 510, and then the controller controls the detergent pump to inject a proper amount of detergent into the boiler mechanism 210 through the detergent pipe 540, and then the motor 110 is started, so that the pot body fixing frame 134 drives the boiler mechanism 210 to move towards the direction close to the pot brush 530 under the action of the guide rod 133. When the pot brush 530 contacts the inner wall of the boiler mechanism 210, the pot brush 530 makes a spiral motion relative to the inner wall of the boiler mechanism 210, and scrapes off the impurities on the inner wall of the boiler mechanism 210 through friction. After the boiler mechanism 210 is cleaned, the motor 110 is further controlled to rotate so that the pot body fixing frame 134 drives the boiler mechanism 210 to move toward the bottom of the pot brush 530 under the action of the guide rod 133 until the suction pipe 520 contacts the bottom of the boiler mechanism 210, and then the suction pump is controlled by an external controller to absorb the cleaning waste water in the boiler mechanism 210 through the suction pipe 520 and discharge it.

[0054] It should be further explained that in the above embodiment of washing the boiler mechanism 210, a small motor may be installed on the pot brush 530 to control the rotation of the pot brush 530, so as to further adjust the relative rotation rate between the pot brush 530 and the inner wall of the boiler mechanism 210, thereby improving the washing effect of the boiler mechanism 210. In other embodiments, the detergent pipe 540 may be connected to other functional pipes to connect other liquid or solid food materials, and the pot brush 530 may be replaced by a stirrer. Under the same working process as above, liquid food materials or powdered or block food materials and water are added to the boiler mechanism 210, and the stirrer stirs the materials in the boiler mechanism 210 to obtain paste or slurry food materials.

[0055] See also Fig.15In one embodiment, the cooking and heat preservation machine further includes a sieve 550 for holding food materials. The sieve 550 is fixedly mounted on the pot body fixing frame 134. After the boiler mechanism 210 heats the water injected through the water injection pipe 510, the pot body fixing frame 134 drives the sieve 550 to rotate and descend until the food materials contact the hot water under the drive of the motor 110 and the transmission of various components to blanch the food materials; the pot body fixing frame 134 drives the sieve 550 to leave the boiler mechanism 210, and after the hot waste water in the boiler mechanism 210 is sucked away through the water suction pipe 520 and clean water is injected into the boiler mechanism 210, the pot body fixing frame 134 drives the sieve 550 to rotate and descend until the food materials contact the cold water to cool down the blanched food materials. In other words, when using the above-mentioned sieve 550, the food in the sieve 550 is first immersed in the water heated in the boiler mechanism 210 for blanching. After the hot water in the boiler mechanism 210 is replaced by cold water, the blanched food is cooled down, thereby achieving the purpose of "passing the food through the cold river".

[0056] The single-drive central axis integrated automatic cooking and warming machine 10 of the present invention can simultaneously drive the spatula assembly 220 to rotate and lift through the cooperation of the lifting transmission member 130 and the turntable 140, so as to flip the food in the boiler mechanism 210, facilitate frying the food, and avoid the problem of sticking the pot. When the lifting transmission member 130 is close to the food distribution unit 300, it can drive the food grid 320 to rotate or lift some parts on the food grid 320, so that the drop hole 331 is opened, and then the food in the food grid 320 is unloaded into the cooking execution unit 200. In this way, the food can be stir-fried and the food can be put into the boiler mechanism 210 by a single motor 110, so as to realize automatic unloading of the cooking operation, reduce the manual operation links, and when driven by a single motor 110, the frying The structure of the food warming machine is simpler, fewer parts are required to complete the functions of the equipment, the cost is reduced, and the overall size of the food warming machine is reduced, which is convenient for users to plan the placement of the equipment in the kitchen; furthermore, the cooking execution unit 200 can adopt a conventional split boiler or an integrated boiler, which improves the compatibility of the automatic food warming machine with existing kitchen utensils, and there is no need to purchase an additional boiler, which further reduces the user's cooking cost; in addition, the various components of the equipment are covered by the outer shell 400 of the food warming machine, and the fumes generated during the cooking process are only discharged through the holes on the top of the cover, which is convenient for discharging the fumes to the outside through an external smoke exhaust fan, avoiding the problem of increased kitchen cleaning workload caused by the use of an open design, when fumes are diffused in the kitchen or grease splashes on the kitchen countertop, reducing the user's labor input, and helping to enhance the market competitiveness of the product.
