Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a cooking device. Background Technology

[0002] In related technologies, cooking equipment, such as stir-fry machines, includes a pot body and a stirring component. The stirring component can extend into the pot body and is set perpendicular to or at a large angle to the inner wall of the pot body. The stirring component can also rotate while abutting against the inner wall of the pot body, so that the rotation of the stirring component drives the food to turn over, thereby realizing the stirring and processing of the food.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0019] The embodiments described in this application are only some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application. In the description of this application, it should be noted that the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In related technologies, cooking equipment includes a pot body and a stirring element. The stirring element can extend into the pot body and is set perpendicular to or at a large angle to the inner wall of the pot body. The stirring element can also rotate against the inner wall of the pot body to drive the food to turn over, thereby achieving the stirring and processing of the food.

[0021] However, when frying rice, mixed grain rice, some bean products, or minced meat and other sticky granular foods, the sticky granular foods are prone to sticking together and forming clumps during the stirring process. This is especially true for cooking equipment with heating functions, which can easily lead to uneven heating of the clumps of food formed during the stirring process.

[0022] It should also be noted that some granular foods may not be sticky or have very little stickiness before processing, making them insufficient to form clumps; however, some granular foods will become sticky after heating, which will also cause them to clump together during stirring.

[0023] For example, when making fried rice with eggs, the food is prone to clump together during the stirring process, such as... Figure 21 As shown.

[0024] To address this issue, research has found that refrigerating rice overnight before making fried rice can reduce or prevent it from clumping together. However, this affects the texture and is also quite cumbersome.

[0025] This application provides a cooking device.

[0026] Please see Figure 1 The cooking device includes a pot body 1.

[0027] The pot body 1 is used for processing food, such as providing space for processing food or heating food through the pot body 1.

[0028] Please see Figure 1 The cooking apparatus also includes a stirring device 2.

[0029] The stirring device 2 is used to stir the food placed in the pot 1.

[0030] Please see Figure 2 The cooking device also includes a heating component 3, which is located below the pot body 1 and is used to heat the pot body 1 and the food inside the pot body 1.

[0031] It is understood that the cooking device can be a food processor without a heating function, or a food cooking device with a heating function, such as a stir-fry machine. The following description mainly uses a stir-fry machine as an example to illustrate this application.

[0032] Please see Figure 1 The stirring device 2 includes a support arm 21 and a stirring element mounted on the support arm 21. The stirring element is used to stir the food placed in the pot 1, and the support arm 21 is used to support the stirring element.

[0033] In some embodiments, the stirring element can be extended into the pot body 1 by the movement of the support arm 21, so that the stirring element can stir and process the food placed in the pot body 1.

[0034] It should be noted that the number of stirring components can be one or more, which is determined by the shape and size of the pot body 1 and the movement mode of the stirring components. In some embodiments, stirring components with different stirring functions can even be provided, which will be described in detail below.

[0035] In some alternative embodiments, the stirring component includes a stirring support and a stirring part, the stirring part being disposed on the stirring support and having a rotation axis, the stirring component, the stirring support and the stirring part being rotatable about the rotation axis, and the stirring part being used to stir and process food during rotation.

[0036] Optionally, the stirring part is connected to one end of the stirring support.

[0037] Optionally, the stirring support is rotatably mounted on the support arm 21 about the axis of rotation.

[0038] As shown in the figure, in some optional embodiments, one end of the stirring support is rotatably mounted directly or indirectly on the support arm 21 about the rotation axis, and the stirring part is connected to one end of the stirring support.

[0039] It is understood that in some optional embodiments, each stirring element may have one stirring part or multiple stirring parts (i.e., two or more, and "multiple" in this application refers to two or more).

[0040] When each mixing component has multiple mixing parts, the shapes and functions of these multiple mixing parts can be the same or different. The design can be based on actual needs, but this does not mean that the solution designed based on actual needs is not creative.

[0041] It should be noted that when each stirring component has multiple stirring parts, these multiple stirring parts are distributed at intervals along the circumference of the stirring support of the stirring component (i.e., the direction of rotation of the stirring support about the rotation axis).

[0042] In some optional embodiments, the stirring device 2 further includes a rotating assembly 23, which is rotatably mounted on the support arm 21 about a rotation axis, and the stirring support is rotatably mounted on the rotating assembly 23 about the rotation axis, so that the stirring support is rotatably mounted on the support arm 21 about the rotation axis. The stirring device 2 is configured such that when the rotating assembly 23 drives the stirring element to rotate around the rotation axis inside the pot body 1, the stirring element rotates around the rotation axis.

[0043] It is understandable that driving the stirring component to rotate around the rotation axis within the pot body 1 via the rotating component 23 is equivalent to driving the stirring component to revolve around the rotation axis, while driving the stirring component to rotate around the rotation axis is equivalent to driving the stirring component to rotate on its own axis.

[0044] It is understood that in some alternative embodiments, multiple stirring elements are provided, and the rotating assembly 23 can drive multiple stirring elements to rotate around the rotation axis.

[0045] In this way, the food in the pot 1 can be stirred by driving the stirring element to "rotate" and "revolve". This can expand the effective stirring area of ​​the stirring element and make the food in the pot 1 be stirred evenly. In this way, the food in the pot 1 can be thoroughly stirred by the cooperation of multiple stirring elements.

[0046] It should be noted that in some embodiments, the stirring element may only have a "rotational" stirring mode. In this case, the extension direction of the rotation axis may be consistent with the depth direction of the pot body 1. The following description mainly focuses on the ability of the stirring element to "rotate" and "revolve".

[0047] It should be noted that when there are multiple stirring components, the multiple stirring components are distributed at intervals along the circumference of the rotating assembly 23 (that is, the rotation direction of the rotating assembly 23 around the rotation axis).

[0048] Please see Figures 3 to 8 During the rotation of the driving agitator, or during the simultaneous rotation and revolution of the driving agitator, at least one agitating part of at least one agitator can break up the clumps of food formed during the mixing process, thereby disrupting the structure of the clumps of food.

[0049] It is understandable that the clump-breaking action refers to the physical interaction between at least one mixing part of at least one mixing element and the clump of food, which can break down the structure of the clump of food.

[0050] For example, the clump-breaking action can be a squeezing action, an impact action, a piercing action, or a cutting action, as long as the structure of the clump of food can be broken during the rotation of the mixing component.

[0051] It should be noted that, for stirring components that can rotate on their own axis and revolve around the axis, during the process of the rotating component 23 driving multiple stirring components to rotate around the axis of rotation, at least one stirring part of at least one stirring component can break up the clumps of food formed during the stirring process, thereby destroying the structure of the clumps of food.

[0052] As mentioned above, cooking food is a complex process. In some implementations, different mixing components can be used to mix the food. For example, some mixing components drive the food to move and tumble by pushing, while others can both mix and break up the structure of clumps of food.

[0053] The following provides a detailed description of this application in conjunction with different functional mixing components and different mixing requirements.

[0054] In some alternative embodiments, as shown in the figure, the structure of the food clumps formed during the stirring process is broken by engaging at least one stirring part of at least one stirring element with the inner wall 11 of the pot.

[0055] For example, in some alternative embodiments, such as Figures 9 to 12 As shown, the stirring component includes a first stirring component 24, a stirring support portion 241 of the first stirring component 24, and one of the stirring portions of the first stirring component 24 is a first stirring portion 242. The rotation axis of the first stirring component 24 is a first rotation axis. That is to say, the first stirring component 24 includes a first stirring support portion 241 and a first stirring portion 242. The first stirring support portion 241 has a first rotation axis and is rotatably mounted on a support arm 21 about the first rotation axis.

[0056] In some alternative embodiments, such as Figures 9 to 12 As shown, one end of the first stirring part 242 is connected to the first stirring support part 241, and the other end extends away from the first stirring support part 241, so that the first stirring part 242 can have a larger stirring area.

[0057] In some alternative embodiments, such as Figures 9 to 11 As shown, the first stirring member 24 is used to extend into the pot body 1. The first stirring part 242 and the inner wall 11 of the pot body form a compression space 246 and a feed port 2425. The feed port 2425 is connected to the compression space 246. The feed port 2425 has one side located in the rotation direction of the first stirring member 24. The stirring device 2 is configured to squeeze the food moving during the stirring process into the compression space 246 through the feed port 2425 when the first stirring member 24 rotates around the first rotation axis, so as to destroy the structure of the clump of food formed during the stirring process.

[0058] It is understood that the first stirring part 242 has a first side part 2421 located in the rotation direction. The first side part 2421 is spaced apart from the inner wall 11 of the pot. An inlet 2425 communicating with the extrusion space 246 is formed between the first side part 2421 and the inner wall 11 of the pot.

[0059] In some alternative embodiments, such as Figures 9 to 12 As shown, the first stirring support 241 is rotatably mounted on the rotating assembly 23 around the first rotation axis. The stirring device 2 is configured such that when the rotating assembly 23 drives the first stirring element 24 to rotate around the rotation axis inside the pot body 1, the first stirring element 24 rotates around the first rotation axis. In this way, the first stirring element 24 can achieve both rotational motion and revolution motion.

[0060] It is understood that when the first stirring component 24 rotates within the pot body 1, or when the first stirring component 24 rotates and revolves within the pot body 1, the first stirring part 242 continuously rotates. The first stirring part 242 continuously forms a compression space 246 between itself and the inner wall 11 of the pot body 1 along its movement trajectory. Food along the movement trajectory of the first stirring part 242 will continuously enter the compression space 246. When the clump of food formed during the stirring process enters the compression space 246, it will be subject to the limiting and squeezing effect of the compression space 246, thereby breaking the internal adhesive structure of the clump of food and breaking it into fine pieces. The broken food leaves the compression space 246 and continues to tumble and mix within the pot body 1.

[0061] In other words, when stirring, such as stir-frying, or handling sticky granular foods like rice, mixed grain rice, some legumes, or minced meat, this application creates a compression space 246 between the first stirring section 242 and the inner wall 11 of the pot. This allows clumps of granular food to be guided into the compression space 246 while the stirring device 2 is stirring the food (e.g., stir-frying). The limiting and compressing effect of the compression space 246 simultaneously breaks down the sticky structure of the clumps during stirring, thereby reducing or even eliminating clumps at the end of cooking. This effectively improves the phenomenon of sticky granular foods clumping together during cooking, thus enhancing the uniformity of stirring.

[0062] For cooking equipment with heating functions, such as stir-fry machines, it can also improve the evenness of food stir-frying.

[0063] In some alternative embodiments, as shown in the figure, the extrusion height H of the extrusion space 246 in the rotational direction of the first agitator 24 gradually increases at least partially.

[0064] It can be understood that the rotation direction of the first stirring element 24 refers to the rotation direction of the first stirring element 24 when it rotates. By gradually increasing the extrusion height of the extrusion space 246 in the rotation direction of the first stirring element 24, the feed inlet 2425 can have a certain height, which makes it easier to collect the clumps of food formed during the stirring process into the extrusion space 246 for extrusion.

[0065] It is understood that the extrusion space 246 forms a height gradient zone from high to low along the rotation direction of the first stirring member 24. During the stirring process, the clump of food first enters the extrusion space 246 through the feed port 2425. Then, as the first stirring member 24 rotates, the clump of food will move downstream of the extrusion space 246 (relatively speaking) and enter the height gradient zone, and gradually be subjected to increasing extrusion force, which will destroy the clump structure.

[0066] Specifically, the first stirring part 242 is at least partially inclined to the inner wall 11 of the pot, so that the extrusion height of the extrusion space 246 in the rotation direction of the first stirring member 24 gradually increases at least partially.

[0067] In some alternative embodiments, as shown in the figure, the opening angle of the compression space 246 is less than or equal to 45 degrees and greater than or equal to 1 degree.

[0068] Specifically, the first stirring section 242 includes a pressing side 2423 for facing the inner wall 11 of the pot, the pressing side 2423 being relative to a plane perpendicular to the first axis of rotation (e.g., Figure 9 and Figure 10 The P-plane shown is inclined, and the distance between the extrusion side 2423 and a plane perpendicular to the first rotation axis gradually increases in the rotation direction of the first stirring member 24, so that an extrusion space 246 is formed between the first stirring part 242 and the inner wall 11 of the pot.

[0069] It can be understood that the extrusion side 2423 can be all the sides of the first stirring part 242 facing the inner wall 11 of the pot, or it can be a part of the side of the first stirring part 242 facing the inner wall 11 of the pot.

[0070] It is understood that the extrusion space 246 includes at least the space formed between the extrusion side 2423 and the inner wall 11 of the pot, that is, the space formed between the extrusion side 2423 and the inner wall 11 of the pot is a height gradient zone.

[0071] It is understood that the inner wall 11 of the pot includes an extrusion mating surface corresponding to the extrusion side 2423, and the opening angle of the extrusion space 246 is the angle between the extrusion side 2423 and the extrusion mating surface.

[0072] If both the extruded side surface 2423 and the extruded mating surface are flat, such as the extruded mating surface being part of the bottom surface of a frying pan.

[0073] If the extrusion side 2423 is an arc-shaped surface, the extrusion simulation surface can be determined by the two sides of the extrusion side 2423 in the rotation direction of the first stirring member 24. If the plane of the two sides passes through the plane, the angle between the extrusion simulation surface and the extrusion mating surface is the opening angle of the extrusion space 246.

[0074] like Figure 9 As shown, if the extrusion mating surface is an arc-shaped surface, the mating simulation surface (as indicated by line HF) can be determined by the two sides of the extrusion mating surface in the rotation direction of the first stirring member 24. If the two sides are planes, the angle between the mating simulation surface and the extrusion side 2423 or the extrusion simulation surface is the opening angle of the extrusion space 246.

[0075] It is understood that the opening angle of the extrusion space 246 is used to characterize the tilt angle between the first stirring part 242 and the inner wall 11 of the pot. The first stirring part 242 has a pushing effect on the food entering the extrusion space 246, which pushes the food to rotate together with the first stirring part 242. On the other hand, it also has a squeezing effect in conjunction with the inner wall 11 of the pot to squeeze the food.

[0076] If the opening angle of the extrusion space 246 is too large, the first stirring part 242 will exert too much resistance on the food entering the extrusion space 246, and because the inner wall 11 of the pot is relatively smooth, the extrusion effect will be too small, causing the food to flip out of the extrusion space 246 under the action of rotational force before it can be extruded into a ball. Therefore, the opening angle of the extrusion space 246 can be less than or equal to 45 degrees.

[0077] If the opening angle of the squeezing space 246 is too small, the squeezing width of the squeezing space 246 may become too long, or the squeezing space 246 may become too small, which is not conducive to squeezing food. Therefore, the opening angle of the squeezing space 246 can be greater than or equal to 1 degree.

[0078] Therefore, by making the opening angle of the compression space 246 less than or equal to 45 degrees and greater than or equal to 1 degree, such as 1 degree, 5 degrees, 8 degrees, 10 degrees, 12 degrees, 15 degrees, 17 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, 30 degrees, 30 degrees, 32 degrees, 34 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 43 degrees or 45 degrees, the compression space 246 can have a better compression effect.

[0079] Experiments show that when the opening angle of the extrusion space 246 is less than or equal to 40 degrees and greater than or equal to 5 degrees, the first stirring component 24 can be better designed under the condition that the extrusion space 246 has a good extrusion effect.

[0080] Experiments show that, under the same conditions, when the opening angle of the compression space 246 is less than or equal to 38 degrees and greater than or equal to 15 degrees, the compression space 246 has a better compression effect.

[0081] Experiments show that, under the same conditions, when the opening angle of the compression space 246 is less than or equal to 35 degrees and greater than or equal to 20 degrees, the compression space 246 has a better compression effect.

[0082] In some optional embodiments, the extrusion side 2423 is a plane, which is suitable for the pan body 1. When the extrusion side 2423 is a plane structure, the tilt angle of the extrusion side 2423 remains consistent at all points, which is suitable for pan cooking scenarios.

[0083] In some alternative embodiments, the extruded side 2423 is an arc surface, which is suitable for flat-bottomed pot body 1 or arc-shaped pot body 1 (such as spherical pot body 1, etc.).

[0084] If the pot body 1 is a flat-bottomed pot and the bottom wall of the pot body 1 is a planar or near-planar structure, then the distance between the extrusion side 2423 and a plane perpendicular to the first rotation axis in a direction away from the first rotation axis can be the same or substantially the same.

[0085] If the pot body 1 is an arc-shaped pot body 1, then the inner wall 11 of the pot body is an arc-shaped surface. If the pot body 1 is a spherical inner wall 11, then the distance between the extrusion side 2423 and a plane perpendicular to the first rotation axis in the direction away from the first rotation axis can be gradually increased, so that the height of the extrusion space 246 is equal or approximately equal in the direction away from the first rotation axis, so that the extruded food can be sent out from the opening of the extrusion space 246 in the direction away from the first rotation axis.

[0086] Understandably, the opening angle of the compression space 246 can be adjusted according to the type of pot body 1, the shape of the inner wall 11 of the pot body, and the type of food.

[0087] In some optional embodiments, the extrusion side 2423 is not the entire side of the first stirring part 242 facing the inner wall 11 of the pot. In this case, the extrusion side 2423 can occupy more than 70% of the side of the first stirring part 242 facing the inner wall 11 of the pot (such as 70%, 75%, 80%, 85%, 90%, 95% or 100%), thus ensuring sufficient extrusion space 246.

[0088] To facilitate the manufacture of the first stirring component 24, the structure of the extrusion side 2423 and the first stirring component 24 itself can be defined. For example, the angle between the extrusion side 2423 and the plane perpendicular to the first rotation axis can be less than or equal to 45 degrees and greater than or equal to 1 degree, so that the opening angle of the extrusion space 246 is less than or equal to 45 degrees and greater than or equal to 1 degree. For example, the angle can be 1 degree, 5 degrees, 8 degrees, 10 degrees, 12 degrees, 15 degrees, 17 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, 30 degrees, 30 degrees, 32 degrees, 34 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 43 degrees or 45 degrees, so that the extrusion space 246 can have a better extrusion effect.

[0089] In some alternative embodiments, the angle between the extruded side 2423 and the plane perpendicular to the first axis of rotation is less than or equal to 38 degrees and greater than or equal to 15 degrees.

[0090] In some alternative embodiments, the angle between the extruded side 2423 and the plane perpendicular to the first axis of rotation is less than or equal to 35 degrees and greater than or equal to 20 degrees.

[0091] In some alternative embodiments, the first stirring section 242 includes a pushing side 2424 facing away from the inner wall 11 of the pot, the trend of the pushing side 2424 being the same as or opposite to the trend of the squeezing side 2423.

[0092] As in Figure 10 In the example shown, the changing trend of the pushing side 2424 is the same as that of the squeezing side 2423.

[0093] As in Figure 11 In the example shown, the trend of change of the pushing side 2424 is opposite to the trend of change of the squeezing side 2423.

[0094] Thus, when the first stirring element 24 rotates in the opposite direction, the pushing side 2424 can push against the food, and even scoop up the food, causing it to flip over.

[0095] Furthermore, the width variation trend of the pushing side 2424 along the rotation direction of the first stirring member 24 is set to be the same as or opposite to the variation trend of the extrusion side 2423.

[0096] In some optional embodiments, the extrusion side 2423 is a helical surface extending away from the rotation axis, and / or, the pushing side 2424 is a helical surface extending away from the rotation axis. Specifically, when the extrusion side 2423 adopts a helical surface structure, the surface gradually and smoothly changes along the rotation direction. During the forward rotation of the first stirring member 24, the helical surface continuously guides the food from a position near the rotation axis to the inner wall 11 of the pot. The food slides smoothly along the helical surface and stably enters the extrusion space 246 enclosed by the extrusion side 2423 and the inner wall 11 of the pot. The continuous transition shape of the helical surface allows the food to have a longer extrusion time, fully completing the extrusion.

[0097] When the pushing side 2424 adopts a spiral curved surface structure, under the condition of the first stirring component 24 rotating in the opposite direction, the spiral curved surface conforms to the food to form a spiral pushing path. The food moves around the curved surface and is evenly dispersed in the radial direction. The food layer continues to roll and rub, improving the overall mixing effect. At the same time, the spiral curved surface has no abrupt sharp corners, which can reduce the adhesion and accumulation of sticky food.

[0098] The following are some examples of the shapes of the first stirring section 242 that meet the requirements of the above extrusion space 246.

[0099] In some alternative embodiments, the first stirring section 242 is plate-shaped.

[0100] For example, the first stirring section 242 is a spiral stirring plate.

[0101] In some optional embodiments, the distance between the first stirring part 242 and a plane perpendicular to the first rotation axis gradually increases in the rotation direction of the first stirring member, and the distance between the first stirring part 242 and a plane perpendicular to the first rotation axis gradually increases in the direction away from the first rotation axis, so that a compression space 246 is formed between the first stirring part 242 and the inner wall 11 of the pot.

[0102] Therefore, it is suitable for curved pot body 1 (such as spherical pot body 1, etc.).

[0103] In some alternative embodiments, the first stirring part 242 is a spiral stirring blade with a gradually increasing distance between it and a plane perpendicular to the axis of rotation in a direction away from the axis of rotation.

[0104] In some optional embodiments, the first stirring part 242 is plate-shaped, the first stirring support part 241 has a support side 24111 located around the first rotation axis, and the first stirring part 242 is arranged in a cross shape on the support side 24111 so that a compression space 246 is formed between the first stirring part 242 and the inner wall 11 of the pot.

[0105] In some alternative embodiments, such as Figure 13As shown, the supporting side 24111 has an inclined first mounting port 24112, and one end of the first stirring part 242 is inserted into the first mounting port 24112 so that the first stirring part 242 is arranged in a cross shape on the supporting side 24111.

[0106] Optionally, the first stirring part 242 and the first stirring support part 241 are metal parts, and one end of the first stirring part 242 is inserted and welded into the mounting port.

[0107] In another embodiment, the first stirring part 242 and the first stirring support part 241 are metal parts, such as... Figure 14 As shown, one end of the first stirring part 242 is formed with a first mounting port 2427 for accommodating a portion of the supporting side 24111. The supporting side 24111 is partially accommodated in the first mounting port 2427, and the first stirring part 242 is welded to the supporting side 24111 at the first mounting port 2427.

[0108] In another embodiment, the first stirring part 242 and the first stirring support part 241 are plastic parts, and the first stirring part 242 and the first stirring support part 241 are integrally formed.

[0109] In some optional embodiments, the first stirring support 241 includes a support base 2411 and a transmission part 2412 connected to one end of the support base 2411. The transmission part 2412 extends in a direction away from the support base 2411, and the first stirring part 242 is connected to the support base 2411.

[0110] Specifically, the supporting side 24111 is provided on the supporting base 2411.

[0111] Optionally, the diameter or equivalent diameter of the support base 2411 is larger than the diameter or equivalent diameter of the transmission part 2412.

[0112] This results in a larger radial dimension for the support base 2411, providing ample installation area for the first stirring part 242. It also increases the mating area between the first stirring part 242 and the support base 2411, making it less prone to bending and deformation when stirring and extruding food.

[0113] The support base 2411 is cylindrical.

[0114] The cylindrical support base 2411 has a smooth outer wall transition, making it less likely for sticky food to adhere and accumulate during rotation, and easier to clean.

[0115] In some alternative embodiments, such as Figure 10 and Figure 11As shown, a discharge gap 2426 is formed between the first stirring part 242 and the inner wall 11 of the pot, which communicates with the extrusion space 246.

[0116] It is understandable that the discharge gap 2426 is located on one side of the first stirring section 242 in the direction of rotation.

[0117] This is understandable; please refer to [link / reference]. Figures 9 to 11 The first stirring part 242 has a second side part 2422 located in the rotation direction. The second side part 2422 is spaced apart from the inner wall 11 of the pot to form a discharge gap 2426.

[0118] This is understandable; please refer to [link / reference]. Figure 9 The distance between the second side portion 2422 and the inner wall 11 of the pot is less than the distance between the first side portion 2421 and the inner wall 11 of the pot, so that the extrusion height of the extrusion space 246 in the rotation direction of the first stirring member 24 gradually increases at least partially.

[0119] During operation, the clumps of food mainly enter the extrusion space 246 through the inlet 2425. After being extruded in the extrusion space 246, they are discharged through the outlet gap 2426. Thus, by setting the outlet gap 2426, it is convenient to send the food with a broken-down clump structure out of the extrusion space 246, so as to prevent the food from moving with the first stirring part 242, and to allow more clumps of food to enter the extrusion space 246 so as to act on more clumps of food.

[0120] In some optional embodiments, the height of the discharge gap 2426 is less than or equal to 12 mm, such as 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm or 12 mm.

[0121] Understandably, the discharge gap 2426 primarily affects the residence time of food within the compression space 246. By setting a suitable discharge gap 2426, clumps of food can be crushed and broken up within the compression space 246 before being discharged through the discharge gap 2426. However, if the discharge gap 2426 is too large, clumps of food may not be sufficiently compressed before being discharged through the discharge gap 2426. Furthermore, an excessively large discharge gap 2426 is also detrimental to the first stirring element 24's ability to push and tumble the food during reverse rotation.

[0122] Through multiple experiments, it has been verified that setting the height of the discharge gap 2426 to less than or equal to 12 mm allows the food to have a longer residence time in the extrusion space 246, so that the clump of food is crushed in the extrusion space 246 and then sent out from the discharge gap 2426.

[0123] Optionally, the height of the discharge gap 2426 is greater than 0.

[0124] In some optional embodiments, the height of the discharge gap 2426 is greater than or equal to 1.5 mm.

[0125] Understandably, if the discharge gap 2426 is too small, the food entering the extrusion space 246 will not be easily discharged from the discharge gap 2426. It will be easily carried by the first stirring part 242 and rotated in the extrusion space 246, which will make it difficult for other clumps of food to enter the extrusion space 246, and may even make them easy to burn.

[0126] Through multiple experiments, it has been verified that setting the height of the discharge gap 2426 to be greater than or equal to 1.5 mm makes it easier for food entering the extrusion space 246 to be discharged from the discharge gap 2426 without affecting the entry of other food into the extrusion space 246.

[0127] In some optional embodiments, the height of the discharge gap 2426 is less than or equal to 9 mm and greater than or equal to 2 mm, which can make the discharge gap 2426 have a better retention and extrusion effect.

[0128] In some optional embodiments, the height of the discharge gap 2426 may be less than or equal to 6 mm and greater than or equal to 3 mm, which may enable the discharge gap 2426 to have a better retention and extrusion effect.

[0129] It is understandable that if the second side portion 2422 is irregular in shape, that is, the height of the discharge gap 2426 varies in the direction away from the first rotation axis, then it is acceptable as long as the height of most (e.g., more than 72%) of the discharge gap 2426 meets the above height range.

[0130] In some optional embodiments, the width of the first stirring section 242 in the rotational direction is greater than or equal to 12 mm, such as 12 mm, 16 mm, 20 mm, 25 mm, 30 mm, 32 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 60 mm, 62 mm, 65 mm, 67 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, 82 mm, 85 mm, 87 mm, 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 110 mm, 120 mm, 130 mm, etc.

[0131] Specifically, the width of the compression space 246 in the rotational direction is greater than or equal to 11.5 mm, and can be 12 mm, 16 mm, 20 mm, 25 mm, 30 mm, 31 mm, 32 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 60 mm, 61 mm, 62 mm, 65 mm, 67 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, 82 mm, 85 mm, 87 mm, 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 110 mm, 120 mm, 125 mm, etc.

[0132] It is understandable that the width of the first stirring part 242 in the rotation direction is used to characterize the width of the extrusion space 246 in the rotation direction. If the width of the extrusion space 246 in the rotation direction is too small, such as less than 11.5 mm, the extrusion space 246 will be too narrow and too small, and will not provide enough space to achieve a good extrusion effect on the clump of food.

[0133] Understandably, the width of the first stirring section 242 in the rotation direction and the width of the extrusion space 246 in the rotation direction are also affected by the size of the pot body 1 (i.e. the maximum cooking weight of the food). For cooking equipment with a maximum cooking weight of less than or equal to 8 kg, the width of the first stirring section 242 in the rotation direction is less than or equal to 130 mm, and the width of the extrusion space 246 in the rotation direction is less than or equal to 125 mm. In some optional embodiments, the width of the first stirring section 242 in the rotational direction is greater than or equal to 32 mm and less than or equal to 62 mm; the width of the extrusion space 246 in the rotational direction is greater than or equal to 31 mm and less than or equal to 61 mm. This allows the extrusion space 246 to provide a larger space for effectively extruding clumps of food.

[0134] It is understandable that if the width of the first stirring section 242 in the rotation direction and the width of the extrusion space 246 in the rotation direction are not the same, but vary, then as long as most (e.g., more than 72%) of the width meets the above width range, it is acceptable.

[0135] In some optional embodiments, the length of the first stirring section 242 in the direction away from the first rotation axis is greater than or equal to 56 mm, and can be 56 mm, 58 mm, 60 mm, 61 mm, 62 mm, 65 mm, 67 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, 82 mm, 85 mm, 87 mm, 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 110 mm, 115 mm, 120 mm, 125 mm, 1... 28 mm, 130 mm, 131 mm, 132 mm, 135 mm, 136 mm, 137 mm, 138 mm, 139 mm, 140 mm, 141 mm, 142 mm, 143 mm, 144 mm, 145 mm, 146 mm, 147 mm, 148 mm, 149 mm, 150 mm, 151 mm, 152 mm, 153 mm, 154 mm, 155 mm, 156 mm, 157 mm, 158 mm, or 160 mm, etc.

[0136] It is understandable that the length of the first stirring part 242 in the direction away from the first rotation axis is used to characterize the length of the extrusion space 246 in the direction away from the first rotation axis. If this length is too small, such as less than 56 mm, the extrusion space 246 is likely to be too short or too small, which will result in the first stirring part 242 having a too small stirring range. For example, the amount of food that can be extruded and processed at one time is limited, and the stirring efficiency is low.

[0137] It is understandable that the length of the first stirring part 242 in the direction away from the first rotation axis and the length of the extrusion space 246 in the direction away from the first rotation axis are also affected by the size of the pot body 1 (i.e. the maximum cooking weight of the food). For cooking equipment with a maximum cooking weight of less than or equal to 8 kg, the length of the first stirring part 242 in the direction away from the first rotation axis is less than or equal to 115 mm.

[0138] In some alternative embodiments, the length of the first stirring section 242 in the direction away from the first axis of rotation is greater than or equal to 72 mm and less than or equal to 115 mm.

[0139] It is understandable that if the length of a stirring section is not consistent in the direction away from the first axis of rotation, but varies, then as long as most (e.g., more than 82%) of the length meets the above length range, it is acceptable.

[0140] Understandably, by setting parameters such as the width of the first stirring section 242, the height of the discharge gap 2426, and the opening angle of the extrusion space 246, the height of the inlet 2425 can be adjusted. Experimental studies have shown that when the height of the inlet 2425 is greater than or equal to 15 mm and less than or equal to 45 mm, it facilitates the entry of food into the extrusion space 246. Suitable heights include 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 35 mm, 38 mm, 40 mm, 42 mm, or 45 mm.

[0141] Optionally, the height of the feed inlet 2425 is greater than or equal to 16 mm and less than or equal to 32 mm.

[0142] It should be noted that when the extrusion side 2423 forming the extrusion space 246 is not planar with the extrusion mating surface, the method for measuring the opening angle of the extrusion space 246 may not be unique. In this case, the opening angle of the extrusion space 246 can be a pre-estimated value. Some deviations in the pre-estimated value will not significantly affect the extrusion effect.

[0143] To better understand this application, as shown in Figure 8 , Figure 9 , Figure 15 , Figure 16 The illustrated embodiment provides two methods for estimating the mouth opening angle.

[0144] exist Figure 8 and Figure 15 In the illustrated embodiment, the pot body 1 is a spherical pot, and the extrusion side 2423 is the side of the first stirring part 242 facing the inner wall 11 of the pot. The distance between the extrusion side 2423 and a plane perpendicular to the first rotation axis gradually increases in the direction away from the first rotation axis. The distance between the first side portion 2421 of the extrusion side 2423 and the inner wall 11 of the pot is equal, and the distance between the second side portion 2422 of the extrusion side 2423 and the inner wall 11 of the pot is equal.

[0145] The first method for estimating the opening angle of the compression space 246: such as Figure 8 and Figure 9 As shown, a point on the first side 2421 of the extrusion side 2423 is designated as point E, and the point with the smallest distance between the first point and the inner wall 11 of the pot is designated as point F. On the second side 2422 of the extrusion side 2423, the point corresponding to the first point is designated as point G, and the point with the smallest distance between the second point and the inner wall 11 of the pot is designated as point H. The opening angle θ can be determined based on these four points.

[0146] The second method for estimating the opening angle of the compression space 246: as follows Figure 15 and Figure 16 As shown, a cross-section is established passing through the center O of the ball and parallel or approximately parallel to the width direction of the first stirring section 242. Within this cross-section, the first side 2421 and the second side 2422 of the extrusion side 2423 form two points, namely the first point M and the second point N. A third point P is found on the inner wall 11 of the pot using a straight line passing through the center of the ball and the first point. The fourth point Q is determined by the point with the smallest distance between the second point and the inner wall 11 of the pot. The opening angle θ can be determined based on these four points.

[0147] Similarly, other parameters related to the extrusion space 246 formed between the first stirring part 242 and the pot body 1, such as the width of the first stirring part 242 in the rotation direction, the height of the discharge gap 2426, the width of the first stirring part 242 in the rotation direction, the width of the extrusion space 246 in the rotation direction, and the length of the first stirring part 242 in the direction away from the first rotation axis, can also be measured or estimated using the same strategy.

[0148] In some alternative embodiments, please refer to Figure 17 The first stirring component 24 also includes a second stirring part 243, one end of which is connected to the first stirring support part 241, and the other end of which extends away from the first stirring support part 241.

[0149] In some alternative embodiments, the first stirring section 242 and the second stirring section 243 are distributed at circumferential intervals along the first stirring support section 241.

[0150] In some optional embodiments, the first stirring part 242 and the second stirring part 243 are located on opposite sides of the stirring support.

[0151] In some optional embodiments, a reverse extrusion space 247 is formed between the second stirring section 243 and the inner wall 11 of the pot, so that the stirring device 2 has the ability to perform dual-rotation extrusion operations.

[0152] The first stirring part 242 can crush the clump of food in the forward rotation direction of the first stirring element 24, and the second stirring part 243 can crush and disperse the clump of food in the reverse rotation direction of the first stirring element 24, thus achieving bidirectional crushing.

[0153] In some alternative embodiments, the extrusion height of the reverse extrusion space 247 gradually increases at least partially in the reverse rotation direction of the agitator.

[0154] It is understood that when the first stirring element 24 rotates in the opposite direction within the pot body 1, or when the first stirring element 24 rotates in the opposite direction and revolves in the opposite direction within the pot body 1, the second stirring part 243 continues to rotate. The second stirring part 243 continuously forms a reverse compression space 247 with the inner wall 11 of the pot body 1 along the movement trajectory. Food along the movement trajectory of the first stirring part 242 will continuously enter the reverse compression space 247. When the clump of food formed during the stirring process enters the reverse compression space 247, it will be subject to the limiting compression effect of the reverse compression space 247, thereby breaking the internal adhesive structure of the clump of food. The broken food leaves the reverse compression space 247 and continues to tumble and mix within the pot body 1.

[0155] It can be understood that the reverse rotation direction of the first stirring element 24 refers to the reverse rotation direction when the first stirring element 24 rotates.

[0156] By gradually increasing at least part of the compression height of the reverse compression space 247 in the reverse rotation direction of the first stirring member 24, the feed inlet 2425 of the second stirring part 243 can have a certain height, which makes it easier to collect the clumps of food formed during the stirring process into the compression space 246 for compression.

[0157] It is understood that the reverse extrusion space 247 forms a height gradient zone from high to low along the reverse rotation direction of the first stirring member 24. The food clumps formed during the stirring process first enter the reverse extrusion space 247 through the feed port 2425 of the second stirring part 243. Then, as the first stirring member 24 rotates in the opposite direction, the food clumps will move downstream of the reverse extrusion space 247 (relatively speaking) and enter the height gradient zone, and gradually be subjected to increasing extrusion force, which may destroy the clump structure.

[0158] Specifically, the second stirring part 243 is at least partially inclined to the inner wall 11 of the pot, so that the extrusion height of the reverse extrusion space 247 in the reverse rotation direction of the first stirring member 24 gradually increases at least partially.

[0159] It is understandable that the arrangement of the second stirring part 243 and the way in which the second stirring part 243 and the pot body 1 form a reverse extrusion space 247 can be referenced from the arrangement of the first stirring part 242, which will be briefly explained below.

[0160] In some alternative embodiments, such as Figure 10 and Figure 11 As shown, the opening angle of the reverse compression space 247 is less than or equal to 45 degrees and greater than or equal to 1 degree.

[0161] It is understandable that the opening angle of the reverse extrusion space 247 is used to characterize the tilt angle between the second stirring part 243 and the inner wall 11 of the pot. The second stirring part 243 has a pushing effect on the food entering the reverse extrusion space 247, which pushes the food to rotate together with the second stirring part 243. On the other hand, it also has a squeezing effect in conjunction with the inner wall 11 of the pot to squeeze the food.

[0162] If the opening angle of the reverse compression space 247 is too large, the first stirring part 242 will exert too much resistance on the food entering the reverse compression space 247, and because the inner wall 11 of the pot is relatively smooth, the compression effect will be too small, causing the food to flip out of the reverse compression space 247 under the action of rotational force before it can be compressed into a ball. Therefore, the opening angle of the reverse compression space 247 can be less than or equal to 45 degrees.

[0163] If the opening angle of the reverse compression space 247 is too small, the compression width of the reverse compression space 247 may become too long, or the reverse compression space 247 may become too small, which is not conducive to compressing food. Therefore, the opening angle of the reverse compression space 247 can be greater than or equal to 1 degree.

[0164] Therefore, by making the opening angle of the reverse compression space 247 less than or equal to 45 degrees and greater than or equal to 1 degree, such as 1 degree, 5 degrees, 8 degrees, 10 degrees, 12 degrees, 15 degrees, 17 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, 30 degrees, 30 degrees, 32 degrees, 34 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 43 degrees or 45 degrees, the reverse compression space 247 can have a better compression effect.

[0165] In some alternative embodiments, the opening angle of the reverse compression space 247 is less than or equal to 40 degrees and greater than or equal to 5 degrees.

[0166] In some alternative embodiments, the opening angle of the reverse compression space 247 is less than or equal to 38 degrees and greater than or equal to 15 degrees.

[0167] In some alternative embodiments, the opening angle of the reverse compression space 247 is less than or equal to 35 degrees and greater than or equal to 20 degrees.

[0168] Understandably, the opening angle of the reverse compression space 247 can be adjusted according to the type of pot body 1, the shape of the inner wall 11 of the pot body, and the type of food.

[0169] In some optional embodiments, the second stirring part 243 includes a reverse extrusion side 2433 for facing the inner wall 11 of the pot. The reverse extrusion side 2433 is inclined relative to the plane perpendicular to the first axis of rotation. The distance between the reverse extrusion side 2433 and a plane perpendicular to the first axis of rotation gradually increases in the rotation direction of the first stirring member 24, so that a reverse extrusion space 247 is formed between the second stirring part 243 and the inner wall 11 of the pot.

[0170] Specifically, the gradually widening inclined slope along the direction of rotation forms a gradual channel. After the food enters the reverse extrusion space 247 as the stirring part rotates, it is continuously subjected to lateral extrusion. The sticky food rubs against each other and breaks up in the channel. The inclined structure can gently guide the food to pass through in an orderly manner and reduce the accumulation of food.

[0171] It is understandable that the arrangement of the reverse extrusion side 2433 on the side of the second stirring part, and the situation in which it forms a reverse extrusion space with the inner wall of the pot, can be referred to the relevant description of the extrusion side 2423, and need not be repeated here.

[0172] In some optional embodiments, the angle between the reverse extrusion side 2433 and the plane perpendicular to the first rotation axis is less than or equal to 45 degrees and greater than or equal to 1 degree.

[0173] In some optional embodiments, the angle between the reverse extrusion side 2433 and the plane perpendicular to the second rotation axis is less than or equal to 45 degrees and greater than or equal to 1 degree, so that the opening angle of the reverse extrusion space 247 is less than or equal to 45 degrees and greater than or equal to 1 degree. For example, it can be 1 degree, 5 degrees, 8 degrees, 10 degrees, 12 degrees, 15 degrees, 17 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, 30 degrees, 30 degrees, 32 degrees, 34 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 43 degrees or 45 degrees, so that the reverse extrusion space 247 can have a better extrusion effect.

[0174] In some optional embodiments, the angle between the reverse extrusion side 2433 and the plane perpendicular to the first rotation axis is less than or equal to 38 degrees and greater than or equal to 15 degrees.

[0175] In some optional embodiments, the angle between the reverse extrusion side 2433 and the plane perpendicular to the first rotation axis is less than or equal to 35 degrees and greater than or equal to 20 degrees.

[0176] In some optional embodiments, the second stirring part 243 includes a reverse pushing side 2434 facing away from the inner wall 11 of the pot, the trend of the reverse pushing side 2434 being the same as or opposite to the trend of the reverse squeezing side 2433.

[0177] The following are some examples of the shapes of the second stirring section 243 that meet the requirements of the reverse extrusion space 247 mentioned above.

[0178] In some alternative embodiments, the second stirring section 243 is plate-shaped.

[0179] For example, the second stirring section 243 is a spiral stirring plate.

[0180] In some optional embodiments, the distance between the second stirring part 243 and a plane perpendicular to the first rotation axis gradually increases in the rotation direction of the first stirring member, and the distance between the second stirring part 243 and a plane perpendicular to the first rotation axis gradually increases in the direction away from the first rotation axis, so that a reverse extrusion space 247 is formed between the second stirring part 243 and the inner wall 11 of the pot.

[0181] Therefore, it is suitable for curved pot body 1 (such as spherical pot body 1, etc.).

[0182] In some alternative embodiments, the second stirring part 243 is a spiral stirring blade with a gradually increasing distance between it and a plane perpendicular to the axis of rotation in a direction away from the axis of rotation.

[0183] In some optional embodiments, the second stirring part 243 is plate-shaped, the first stirring support part 241 has a support side 24111 located on the periphery of the first rotation axis, and the second stirring part 243 is arranged in a cross shape on the support side 24111 so that a compression space 246 is formed between the second stirring part 243 and the inner wall 11 of the pot.

[0184] In some alternative embodiments, such as Figure 17 As shown, the first stirring part 242 is plate-shaped, and the second stirring part 243 is plate-shaped. The first stirring part 242 and the second stirring part 243 are respectively arranged in a cross shape at different positions on the supporting side 24111. The crossing direction of the first stirring part 242 and the supporting side 24111 is different from the crossing direction of the second stirring part 243 and the supporting side 24111.

[0185] Specifically, the supporting side 24111 is provided on the supporting base 2411.

[0186] In some optional embodiments, the supporting side 24111 has an inclined second mounting port, and one end of the second stirring part 243 is inserted into the second mounting port, so that the second stirring part 243 is arranged in a cross shape on the supporting side 24111. The inclination direction of the first mounting port 24112 is different from the inclination direction of the second mounting port.

[0187] Optionally, the second stirring part 243 and the first stirring support part 241 are metal parts, and one end of the second stirring part 243 is inserted and welded into the mounting port.

[0188] In another embodiment, the second stirring part 243 and the first stirring support part 241 are metal parts. One end of the second stirring part 243 is formed with a second mounting port for accommodating a portion of the support side 24111. The support side 24111 is partially accommodated in the second mounting port, and the second stirring part 243 is welded to the support side 24111 at the second mounting port.

[0189] In another embodiment, the second stirring part 243 and the first stirring support part 241 are plastic parts, and the second stirring part 243 and the first stirring support part 241 are integrally formed.

[0190] In some optional embodiments, a reverse discharge gap 2436 is formed between the second stirring section 243 and the inner wall 11 of the pot, communicating with the reverse extrusion space 247. Specifically, the food that has been kneaded and refined by the reverse extrusion space 247 can be continuously discharged through the reverse discharge gap 2436, avoiding the accumulation and retention of food in the reverse extrusion space 247, and ensuring the continuous and smooth reverse extrusion processing.

[0191] In some alternative embodiments, please refer to Figure 4 The second stirring part 243 has a third side part 2431 and a fourth side part 2432 located in the rotation direction. The fourth side part 2432 is spaced apart from the inner wall 11 of the pot to form a reverse discharge gap 2436.

[0192] The third side portion 2431 is spaced apart from the inner wall 11 of the pot, and a reverse feed port 2435 communicating with the reverse extrusion space 247 is formed between the third side portion 2431 and the inner wall 11 of the pot.

[0193] The distance between the fourth side portion 2432 and the inner wall 11 of the pot is less than the distance between the third side portion 2431 and the inner wall 11 of the pot.

[0194] Specifically, the food flows into the reverse extrusion space 247 from the wider reverse feed inlet 2435 to complete the extrusion and refinement. The processed food flows out in an orderly manner through the narrow reverse discharge gap 2436. The gradually changing gap can prolong the extrusion time of the food, fully break up the clumps of food, and at the same time prevent large pieces of unrefined food from flowing out directly.

[0195] In some optional embodiments, the height of the reverse discharge gap 2436 is less than or equal to 12 mm, such as 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm or 12 mm.

[0196] Optionally, the height of the reverse discharge gap 2436 is greater than 0.

[0197] In some optional embodiments, the height of the reverse discharge gap 2436 is greater than or equal to 1.5 mm.

[0198] In some optional embodiments, the height of the reverse discharge gap 2436 is less than or equal to 9 mm and greater than or equal to 2 mm, which can make the reverse discharge gap 2436 have a better retention and extrusion effect.

[0199] In some optional embodiments, the height of the reverse discharge gap 2436 is less than or equal to 6 mm and greater than or equal to 3 mm, which can make the reverse discharge gap 2436 have a better retention and extrusion effect.

[0200] In some optional embodiments, the width of the second stirring section 243 in the opposite rotation direction is greater than or equal to 12 mm, such as 12 mm, 16 mm, 20 mm, 25 mm, 30 mm, 32 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 60 mm, 62 mm, 65 mm, 67 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, 82 mm, 85 mm, 87 mm, 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 110 mm, 120 mm, 130 mm, etc.

[0201] Specifically, the width of the reverse compression space 247 in the reverse rotation direction is greater than or equal to 11.5 mm, such as 12 mm, 16 mm, 20 mm, 25 mm, 30 mm, 31 mm, 32 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 60 mm, 61 mm, 62 mm, 65 mm, 67 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, 82 mm, 85 mm, 87 mm, 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 110 mm, 120 mm, 125 mm, etc.

[0202] In some optional embodiments, the width of the second stirring section 243 in the reverse rotation direction is greater than or equal to 32 mm and less than or equal to 62 mm; the width of the reverse extrusion space 247 in the reverse rotation direction is greater than or equal to 31 mm and less than or equal to 61 mm. This allows the reverse extrusion space 247 to provide a larger space for effectively extruding clumps of food.

[0203] In some optional embodiments, the length of the second stirring section 243 in the direction away from the first rotation axis is greater than or equal to 56 mm, and can be 56 mm, 58 mm, 60 mm, 61 mm, 62 mm, 65 mm, 67 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, 82 mm, 85 mm, 87 mm, 90 mm, 92 mm, 95 mm, 98 mm, 100 mm, 110 mm, 115 mm, 120 mm, 125 mm, 1... 28 mm, 130 mm, 131 mm, 132 mm, 135 mm, 136 mm, 137 mm, 138 mm, 139 mm, 140 mm, 141 mm, 142 mm, 143 mm, 144 mm, 145 mm, 146 mm, 147 mm, 148 mm, 149 mm, 150 mm, 151 mm, 152 mm, 153 mm, 154 mm, 155 mm, 156 mm, 157 mm, 158 mm, or 160 mm, etc.

[0204] In some alternative embodiments, the length of the second stirring section 243 in the direction away from the first axis of rotation is greater than or equal to 72 mm and less than or equal to 115 mm.

[0205] In some optional embodiments, the height of the inlet 2425 of the reverse extrusion space 247 is greater than or equal to 15 mm and less than or equal to 45 mm, which facilitates food entry into the extrusion space 246. The height can be 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 35 mm, 38 mm, 40 mm, 42 mm, or 45 mm.

[0206] Optionally, the height of the feed inlet 2425 of the reverse extrusion space 247 is greater than or equal to 16 mm and less than or equal to 32 mm.

[0207] In some alternative embodiments, please refer to Figure 4 , Figure 5 and Figure 7 The stirring device 2 further includes a rotating assembly 23, which is rotatably mounted on the support arm 21 about a rotation axis. The first stirring support 241 is rotatably mounted on the rotating assembly 23 about the first rotation axis, such that the first stirring support 241 is rotatably mounted on the support arm 21 about the first rotation axis. The stirring device 2 is configured such that when the rotating assembly 23 drives the first stirring element 24 to rotate about the rotation axis inside the pot body 1, the first stirring element 24 rotates about the first rotation axis.

[0208] Optionally, please refer to Figures 18 to 21 The stirring device 2 further includes a second stirring element 25, which has a second rotation axis and is rotatably mounted on the rotating assembly 23 about the second rotation axis.

[0209] The stirring device 2 is configured such that when the rotating assembly 23 drives the first stirring element 24 and the second stirring element 25 to rotate around the rotation axis inside the pot body 1, the first stirring element 24 rotates around the first rotation axis and the second stirring element 25 rotates around the second rotation axis.

[0210] That is to say, when the rotating component 23 drives the first stirring component 24 and the second stirring component 25 to revolve around the rotation axis, the first stirring component 24 rotates around the first rotation axis, and the second stirring component 25 rotates around the second rotation axis.

[0211] Wherein, the stirring part of the second stirring member 25 abuts against the inner wall 11 of the pot, or the distance between the stirring part of the second stirring member 25 and the inner wall 11 of the pot is less than or equal to 3 mm and greater than or equal to 0.3 mm, such as 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0212] It should be noted that, in this embodiment, the first stirring member 24 may only include the first stirring part 242, or it may include the first stirring part 242 and the second stirring part 243. Figure 6 The present case is that the first stirring component 24 includes a first stirring section 242 and a second stirring section 243.

[0213] It is understood that by making the stirring part of the second stirring member 25 abut against the inner wall 11 of the pot, or by making the distance between the stirring part of the second stirring member 25 and the inner wall 11 of the pot less than or equal to 3 mm and greater than or equal to 0.3 mm, the function of the second stirring member 25 can be to push and drive the food to move and tumble to achieve stirring.

[0214] In this way, the first stirring element 24 and the second stirring element 25 can work together to cook viscous granular food. Specifically, when the granular food is first put into the pot, the first stirring element 24 and the second stirring element 25 stir the granular food through their respective stirring parts through their revolution and rotation. During the stirring process, especially when heating simultaneously, the granular food may stick together. At this time, the clump of food can be introduced into the extrusion space 246 or the reverse extrusion space 247 for extrusion and crushing. The crushed food will then be pushed and turned by the stirring part of the second stirring element 25 and continue to roll in the pot body 1.

[0215] Similarly, food that is pushed and turned by the stirring part of the second stirring member 25, especially when heated simultaneously, may clump together again, and the clumps of food may be crushed again by the first stirring member 24.

[0216] This application allows for repeated stirring of food within the pot 1 through the cooperation of the first stirring element 24 and the second stirring element 25. The clumps of food generated during the stirring process can be broken up by the first stirring element 24. After the food with the adhesive structure broken up by the first stirring element 24 is further acted upon by the second stirring element 25, the two work together to fully stir the food, thereby improving the uniformity of stirring.

[0217] It is understandable that, in order to achieve the effect of pushing and stirring, the stirring part of the second stirring element 25 is usually set at a large angle to the inner wall 11 of the pot, such as the included angle being greater than or equal to 55 degrees and less than or equal to 88 degrees.

[0218] Optionally, the first stirring element 24 and the second stirring element 25 are arranged at intervals along the circumference of the rotating assembly 23.

[0219] In a specific embodiment, the number of the second stirring element 25 can be one, two, three, or even four, and its number is affected by the size of the pot body 1.

[0220] Similarly, the number of first stirring components 24 can be one, two, three, or even four, depending on the size of the pot body 1.

[0221] When there are multiple first stirring elements 24 and multiple second stirring elements 25, the first stirring elements 24 and the second stirring elements 25 are arranged alternately.

[0222] In an alternative embodiment, such as Figure 18 As shown, there are two second stirring components 25, namely the first scraper stirring shovel 251 and the second scraper stirring shovel 252.

[0223] Optionally, the first scraper-shaped stirring spatula 251 abuts against the inner wall 11 of the pot, which can scrape off the food adhering to the pot wall and prevent food from sticking and accumulating.

[0224] Optionally, the distance between the second scraper-shaped stirring spatula 252 and the inner wall 11 of the pot is less than or equal to 3 mm, which can not only help to stir the food, but also prevent the spatula from continuously rubbing against the pot wall and wear out, thus extending the service life of the parts.

[0225] Of course, in other embodiments, the second scraper-shaped stirring spatula 252 may also abut against the inner wall 11 of the pot.

[0226] To illustrate the technical effects of this application, a control experiment is provided, the specific experimental details of which are as follows: In the experiments provided in this application, the experimental group provided, as follows: Figure 6 The stirring device 2 of the cooking apparatus shown includes one first stirring element 24 and two second stirring elements 25, as provided in the control group. Figure 19 and Figure 20 The stirring device 2 of the cooking apparatus shown includes three second stirring elements 25. The installation position, installation angle, and rotation mode of the three stirring elements in the experimental group are the same as those in the control group. The only difference is that one of the stirring elements in the stirring device 2 of the experimental group is a first stirring element 24, while the corresponding stirring element in the control group is a second stirring element 25 with a pushing stirring function.

[0227] In the experiment, two sets of cooking devices used rice flour steamed in the same pot and eggs purchased from the same batch to make fried rice in the same environment, with the same cooking time for both. Figure 21 The fried rice prepared as a control group clearly formed clumps of rice. Figure 22 The egg fried rice prepared for the experimental group did not form any rice balls.

[0228] It is understandable that the structure of clumped food can also be disrupted in other ways, such as through impact. Examples are given below.

[0229] In some alternative embodiments, such as Figures 23 to 26 As shown, the stirring component includes a third stirring component 27, which is used to impact the clump of food during rotation or rotation + revolution to break down the structure of the clump of food.

[0230] Optionally, the third stirring element 27 is mounted on the support arm 21, which is movably mounted on the frame 31. The support arm 21 has a working position for extending the third stirring element 27 into the pot body 1 to stir the food inside the pot body 1.

[0231] Specifically, such as Figures 23 to 26 As shown, the stirring support portion of the third stirring member 27 is the second stirring support portion 271, the stirring portion of the third stirring member 27 is the third stirring portion 272, and the rotation axis of the third stirring member 27 is the fourth rotation axis. That is to say, the third stirring member 27 includes the second stirring support portion 271 and the third stirring portion 272, the second stirring support portion 271 has the third rotation axis, and the second stirring support portion 271 is rotatably mounted on the support arm 21 about the fourth rotation axis.

[0232] Optionally, one end of the second stirring support 271 is rotatably mounted on the support arm 21 about the fourth rotation axis, and the third stirring part 272 is provided at the other end of the second stirring support 271.

[0233] Optionally, the third stirring section 272 includes a plurality of impact sections 2722, and a material passage gap 2723 is formed between adjacent impact sections 2722.

[0234] Optionally, the stirring device 2 is configured such that when the third stirring element 27 rotates around the fourth rotation axis, a plurality of the impacting parts 2722 impact the clumps of food formed during the stirring process to break the structure of the clumps of food, and the food broken after impact passes through the material passage gap 2723.

[0235] In other words, when stirring, such as stir-frying, rice, mixed grain rice, some bean products, or minced meat and other sticky granular foods, this application can break down the structure of the clumps of food formed during the stirring process by impacting the food clumps formed during the stirring process through the multiple impact parts 2722 of the third stirring part 272. Moreover, the food broken down by the impact can pass through the material passage gap 2723. In this way, the clumps of food can be reduced or even eliminated at the end of cooking, thereby effectively improving the phenomenon of sticky granular foods sticking together during the cooking process, and thus improving the uniformity of stirring.

[0236] In some optional embodiments, the third stirring part 272 includes a transverse support part 2721 connected to the other end of the second stirring support part 271, and a plurality of impact parts (2722) connected to the transverse support part 2721. The plurality of impact parts 2722 are spaced apart along the extending direction of the transverse support part 2721, so that a material passage gap 2723 is formed between adjacent impact parts 2722, which is beneficial for the food to pass smoothly through the material passage gap 2723 after impact.

[0237] In some optional embodiments, the plurality of impact portions 2722 include a first impact portion 27221 and a fourth impact portion 27224, which are formed by bending and extending from both ends of the transverse support portion 2721, resulting in higher overall structural strength.

[0238] In some alternative embodiments, the plurality of impact portions 2722 include a first set of impact portions 2722 located on one side of the stirring support portion and a second set of impact portions 2722 located on the other side of the stirring support portion.

[0239] Optionally, the impact portion 2722 of the first group of impact portions 2722 is inclined in a direction away from the second group of impact portions 2722, which is beneficial to increase the impact contact range between the impact portion 2722 and the granular food.

[0240] Optionally, the impact portion 2722 of the second group of impact portions 2722 is inclined in a direction away from the first group of impact portions 2722, which is beneficial to increase the impact contact range between the impact portion 2722 and the granular food.

[0241] In some alternative embodiments, the first group of impact parts 2722 includes a first impact part 27221, and the second group of impact parts 2722 includes a fourth impact part 27224.

[0242] In some alternative embodiments, the plurality of impact portions 2722 includes a second impact portion 27222 and a third impact portion 27223.

[0243] Optionally, the second impact part 27222 and the third impact part 27223 are located between the first impact part 27221 and the fourth impact part 27224, and the second impact part 27222 and the third impact part (27223) are respectively fixedly connected to the transverse support part 2721.

[0244] The second impact part 27222 and the third impact part 27223 are inclined towards each other, that is, the second impact part 27222 is inclined toward the first impact part 27221, and the third impact part 27223 is inclined toward the fourth impact part 27224, so that a gradual material passage gap (2723) is formed between the second impact part 27222 and the third impact part 27223.

[0245] Optionally, the width of the material passage gap (2723) near the end of the transverse support (2721) is smaller than the width of the end away from the transverse support (2721).

[0246] In some optional embodiments, the first group of impact parts 2722 includes a first impact part 27221 and a second impact part 27222, and the second group of impact parts 2722 includes a fourth impact part 27224 and a third impact part 27223.

[0247] In some alternative embodiments, each impact part 2722 is a rod with a circular cross-section, which is less likely to scratch and damage the pot body 1.

[0248] Furthermore, the free ends of each impact part 2722 are all configured with arc-shaped transition surfaces. The arc-shaped transition surfaces can gently push the food at the bottom of the pot, reducing the probability of food sticking to the impact parts 2722.

[0249] In some alternative embodiments, the impact portion 2722 is spaced apart from the inner wall 11 of the pot. This avoids scratching the pot or creating noise.

[0250] In some alternative embodiments, the third stirring section is a rake-shaped stirring section.

[0251] In some alternative embodiments, the width of the material passage gap 2723 is greater than or equal to 5 mm and less than or equal to 25 mm, for example, it may be 5 mm, 10 mm, 15 mm, 20 mm or 25 mm.

[0252] In some optional embodiments, the length of the impact portion 2722 along its own extending direction is greater than or equal to 10 mm and less than or equal to 60 mm, and can be 10 mm, 20 mm, 30 mm, 40 mm, 50 mm or 60 mm.

[0253] In some optional embodiments, the impact part 2722 is spaced apart from the inner wall 11 of the pot, and the distance between the stirring part and the inner wall 11 of the pot is less than or equal to 3 mm and greater than or equal to 0.3 mm, and can be 0.3 mm, 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm or 3.0 mm.

[0254] In some alternative embodiments, please refer to Figure 25 The stirring device 2 also includes a stirring scraper 26, which is used to scrape off the food adhering to the upper part of the inner wall of the pot in real time, so as to prevent the food from sticking to the pot wall for a long time and causing it to burn.

[0255] In some alternative embodiments, such as Figure 26 As shown, the middle part of the transverse support 2721 is fixedly connected to the end of the second stirring support 271, and the transverse support 2721 extends symmetrically to both sides with the rotation axis of the second stirring support 271 as the center.

[0256] Specifically, the symmetrically arranged transverse support parts 2721 are subjected to uniform force, run smoothly during rotation, and can uniformly bear the stirring structure, which is conducive to improving the overall stirring stability.

[0257] In some optional embodiments, each impact portion 2722 extends from the transverse support portion 2721 toward the bottom of the pot body 1, and all impact portions 2722 extend in the same direction.

[0258] Specifically, when the impact parts 2722 arranged in the same direction rotate synchronously with the transverse support parts 2721, they can create regular and uniform impact disturbances on the food at the bottom of the pot, preventing local food from being compacted and clumped together, which is conducive to improving the food dispersing effect.

[0259] In some alternative embodiments, the first impact portion 27221 and the fourth impact portion 27224 are respectively formed by bending and extending the two ends of the transverse support portion 2721, resulting in higher overall structural strength.

[0260] In some optional embodiments, the plurality of impact parts (2722) includes a second impact part (27222) and a third impact part (27223). The second impact part (27222) and the third impact part (27223) are located between the first impact part (27221) and the fourth impact part (27224). The first impact part 27221, the second impact part 27222, the third impact part 27223 and the fourth impact part 27224 are distributed sequentially and at intervals along the extension direction of the transverse support part 2721, which can cover a wider area of ​​the bottom of the pot, form multi-point synchronous impact disturbance on the food, reduce the local compaction and clumping of food at the bottom of the pot, and make the food looser and more uniform.

[0261] In some optional embodiments, the second impact part 27222 and the third impact part 27223 are respectively fixedly connected to the transverse support part 2721. The installation position can be adjusted as needed. The multi-point cooperation can comprehensively disturb the food at the bottom of the pot and reduce the situation of food compaction and clumping.

[0262] In some optional embodiments, the second impact part 27222 and the third impact part 27223 are inclined towards each other, with the second impact part 27222 inclined toward the first impact part 27221 and the third impact part 27223 inclined toward the fourth impact part 27224, so that a gradual material passage gap 2723 is formed between the second impact part 27222 and the third impact part 27223. The width of the material passage gap 2723 near the lateral support part 2721 is smaller than the width away from the lateral support part 2721. The gradual material passage gap 2723, which is wider at the bottom and narrower at the top, can guide the food at the bottom of the pot. Large pieces of sticky food will be intercepted by the gap and broken up by impact, while fine pieces of food can pass through the gap smoothly, reducing the accumulation and compaction of food.

[0263] In some alternative embodiments, the width of the material passage gap 2723 is greater than or equal to 8 mm and less than or equal to 25 mm.

[0264] Specifically, when the width of the material passage gap 2723 is less than 8mm, large pieces of food that are stuck together are easily trapped, causing food to accumulate; when the width of the material passage gap 2723 is greater than 25mm, large pieces of food can pass directly through the gap, reducing the impact and breaking-up effect. Controlling the gap width between 8mm and 25mm can both prevent unbroken clumps of food from being continuously impacted and processed, and allow fine pieces of food to pass through smoothly, evenly disturbing the food at the bottom of the pot.

[0265] In some optional embodiments, the length of the impact portion 2722 along its own extending direction is greater than or equal to 20 mm and less than or equal to 60 mm.

[0266] When the length of the impact part 2722 is less than 20mm, the distance it extends into the bottom of the pot is insufficient, making it difficult to fully contact the food at the bottom, resulting in a weak impact disturbance effect. When the length of the impact part 2722 is greater than 60mm, it is easy to scrape against the bottom of the pot, which will also increase the probability of food getting stuck.

[0267] By keeping the length between 20mm and 60mm, it can fully contact the food at the bottom of the pot, stably exert the impact and break up the food, and at the same time reduce the problem of food getting stuck.

[0268] In some alternative embodiments, each impact part 2722 is a rod with a circular cross-section, which is less likely to scratch and damage the pot body 1.

[0269] Furthermore, the free ends of each impact part 2722 are all configured with arc-shaped transition surfaces. The arc-shaped transition surfaces can gently push the food at the bottom of the pot, reducing the probability of food sticking to the impact parts 2722.

[0270] In some alternative embodiments, please refer to Figure 2 The cooking device is a stir-fry robot. The cooking device also includes a frame 31 with a working surface. The pot body 1 is placed above the working surface. The support arm 21 is movably mounted on the frame 31. The support arm 21 has a working position for inserting a stirring component, such as a first stirring component 24, into the pot body 1 to stir the food in the pot body 1.

[0271] Optionally, a heating device (not shown in the figure) is provided below the working surface, or a heating device is provided at the bottom of the pot body 1.

[0272] This allows for automated cooking, such as automatically making fried rice with eggs.

[0273] Optionally, the support arm 21 also has a clearance position for moving the stirring element, such as the first stirring element 24, outside the pot body 1 to avoid the movement of the pot body 1.

[0274] In some optional embodiments, the stirring device 2 further includes a drive assembly 22 mounted on the support arm 21, the drive assembly 22 being used to drive the stirring element to rotate about the rotation axis.

[0275] For example, the drive assembly 22 is used to drive the first stirring element 24 to rotate around the first rotation axis.

[0276] For example, the drive assembly 22 is used to drive the second stirring element 25 to rotate around the second rotation axis.

[0277] For example, the drive assembly 22 is used to drive the third stirring element 27 to rotate around the third rotation axis.

[0278] Optionally, the driving component 22 is also used to drive the rotating component 23 to rotate about the rotation axis.

[0279] Of course, the drive assembly 22 can also be installed inside the frame 31, and drive the stirring component and the rotating assembly 23 to rotate through the transmission part 2412.

[0280] In some alternative embodiments, the drive assembly 22 includes a drive motor 221, a first drive bevel gear 222, and a second drive bevel gear 223.

[0281] The drive motor 221 is installed inside the support arm 21. The drive motor 221 has a drive shaft. The first drive bevel gear 222 and the second drive bevel gear 223 are sequentially installed on the drive shaft. The drive motor 221 drives the rotating component 23 and the stirring component to rotate through the first drive bevel gear 222 and the second drive bevel gear 223 respectively.

[0282] Optionally, the support arm 21 includes a cantilever and a housing covering the cantilever.

[0283] Optionally, the drive motor 221 is mounted on the cantilever.

[0284] In some alternative embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the rotating assembly 23 includes a rotating seat 231, a revolution transmission pair 232, and a rotation transmission pair 233.

[0285] The revolution transmission pair 232 includes a driven bevel gear 2321, a first driving bevel gear 222 meshing with the driven bevel gear 2321, the driven bevel gear 2321 being connected to the rotating seat 231, and all the stirring components being connected to the rotating seat 231, thereby driving the rotating seat 231 and all the stirring components to rotate.

[0286] The self-rotating transmission pair 233 includes a first transmission bevel gear 2331, a second transmission bevel gear 2332, a transmission shaft 2333, and a self-rotating bevel gear 2334. The second driving bevel gear 223 is connected to the first transmission bevel gear 2331. The first transmission bevel gear 2331 and the second transmission bevel gear 2332 are fixedly connected through the transmission shaft 2333 and rotate together. The second transmission bevel gear 2332 meshes with all the self-rotating bevel gears 2334. Each self-rotating bevel gear 2334 is connected to the corresponding stirring component, thereby driving the corresponding stirring component to rotate.

[0287] It should be noted that for cooking devices that need to break up food clumps, the stirring device 2 of the cooking device may include one first stirring element 24 and two second stirring elements 25, or the stirring device 2 of the cooking device may include one first stirring element 24, one second stirring element 25 and one third stirring element 27, or the stirring device 2 of the cooking device may include two second stirring elements 25 and one third stirring element 27; even the stirring device 2 of the cooking device may include one first stirring element 24 and one second stirring element 25, or the stirring device 2 of the cooking device may include two first stirring elements 24 and one second stirring element 25; and so on.

[0288] It should be noted that the first stirring member 24 may include a first stirring section 242, that is, the first stirring member 24 has a stirring section, such as... Figure 12 As shown; or, the first stirring member 24 may include a first stirring section 242 and a second stirring section 243, that is, the first stirring member 24 has two stirring sections, such as... Figure 17 As shown; or, the first stirring member 24 may include a first stirring section 242, a second stirring section 243, and a fourth stirring section 244, that is, the first stirring member 24 has three stirring sections, such as... Figure 27As shown; or, the first stirring member 24 may include a first stirring section 242, a second stirring section 243, a fourth stirring section 244, and a fifth stirring section 245, that is, the first stirring member 24 has four stirring sections, such as... Figure 28 As shown; etc.

[0289] It should be noted that the supporting base 2411 of the first stirring component 24 can be a solid structure, such as... Figure 13 As shown; or, the support base 2411 of the first stirring member 24 can be a bifurcated structure, such as... Figure 29 As shown; etc.

[0290] In addition, this application also provides a control method that can be implemented using at least the above-mentioned cooking equipment.

[0291] Specifically, the aforementioned cooking equipment can use this control method to complete the food stir-frying process.

[0292] The technical solution of this embodiment allows at least one stirring part to interact with the clumps of food formed during the stirring process. This enables the application of force to the clumps of food simultaneously on the basis of conventional stir-frying. By relying on a specific stirring part to break up the agglomerated structure of the food clumps formed during the stirring process, it is beneficial to break up the clumps of food simultaneously during stirring and stir-frying, reduce the phenomenon of food clumping, and improve the uniformity of stir-frying and heating of food in the pot.

[0293] Please see Figure 30 , Figure 30 This is a flowchart illustrating the control method provided in this application. In some optional embodiments, the control method includes: S1: Control drive assembly 22 to drive rotary assembly 23 to rotate around the rotation axis, so as to drive multiple stirring components rotatably mounted on drive assembly 22 to rotate around the rotation axis.

[0294] It is understood that this control method is applied to the cooking equipment provided in the above embodiments, that is to say, the cooking equipment provided in the above embodiments can execute the control method provided in this application.

[0295] Optionally, the cooking device includes a processor, which, upon receiving an instruction, controls the drive component 22 to drive the rotating component 23 to rotate around the rotation axis.

[0296] S2: Control drive assembly 22 drives the stirring component to rotate around the rotation axis, thereby driving the stirring part of the stirring component to rotate and stir the food.

[0297] Optionally, after receiving the instruction, the processor simultaneously controls the control drive component 22 to drive the stirring component to rotate around the rotation axis.

[0298] It is understandable that when there are multiple stirring components, the drive assembly 22 drives each stirring component to rotate around its respective rotation axis. For example, it drives the first stirring component to rotate around the first rotation axis and drives the second stirring component to rotate around the second rotation axis. Or, for example, it drives the first stirring component to rotate around the first rotation axis and determines that the third stirring component rotates around the fourth rotation axis.

[0299] Step S2: During the process of the rotating component (23) driving the multiple stirring components to rotate around the rotation axis, and the driving component (22) driving the stirring components to rotate around the rotation axis, at least one stirring part of at least one stirring component has a breaking action on the clump of food formed during the stirring process, so as to destroy the structure of the clump of food.

[0300] It is understandable that the clump-breaking action refers to the physical interaction between at least one mixing part of at least one mixing element and the clump of food, which can break down the structure of the clump of food.

[0301] For example, the clump-breaking action can be a squeezing action, an impact action, a piercing action, or a cutting action, as long as the structure of the clump of food can be broken during the rotation of the mixing component.

[0302] In other words, during the process of the driving component driving each mixing element to rotate and revolve, at least one mixing part of at least one mixing element interacts with the clump of food through physical means, such as impact or compression, thereby breaking the internal binding structure of the clump of food and breaking the clump of food into fine pieces.

[0303] Understandably, for cooking devices with a first stirring element, methods for controlling the breaking up of clumps of food include: During the process of the drive assembly 22 driving multiple stirring components to rotate around the rotation axis through the rotating assembly 23 and synchronously driving the stirring components to rotate around the rotation axis, the clumps of food formed during the stirring process are squeezed between the first stirring part 242 of the first stirring component 24 and the inner wall 11 of the pot, so as to destroy the structure of the clumps of food formed during the stirring process by the squeezing force formed between the first stirring part 242 and the inner wall 11 of the pot during the rotation.

[0304] It is understandable that, in the embodiment where a compression space 246 and a feed inlet 2425 are formed between the first stirring part 242 and the inner wall 11 of the pot body 1, the feed inlet 2425 is connected to the compression space 246, and the compression height of the compression space 246 gradually increases at least partially in the rotational direction of the first stirring member 24, the method for controlling the breaking up of clumps of food includes: When the rotating component 23 drives the first stirring component 24 to rotate around the rotation axis, and the driving component 22 drives the first stirring component 24 to rotate around the rotation axis, the inlet 2425 and the extrusion space 246 formed between the first stirring part 242 and the inner wall 11 of the pot body 1 move along with it. The clump of food located on the movement path is collected into the extrusion space 246 through the inlet 2425 and gradually moves into the depth of the extrusion space 246. During the process of the clump of food moving into the depth of the extrusion space 246, the adhesive structure of the clump of food is gradually broken by the extrusion space 246, whose extrusion height gradually decreases.

[0305] It is understood that, for embodiments with a discharge gap, the control method further includes: After the food clumps with an adhesive structure are broken down into small particles by the compression space 246, they are sent out from the discharge gap 2426.

[0306] It is understood that, for embodiments with a second stirring section, the control method further includes: The control drive assembly 22 drives the first stirring member 24 to rotate in the opposite direction around the rotation axis, so as to drive the stirring part of the first stirring member 24 to rotate in the opposite direction and stir the food. During the reverse rotation, the reverse feed port 2435 and the reverse space 247 formed between the second stirring part 243 and the inner wall 11 of the pot body 1 move along with it. The clump of food located on the movement path is drawn into the reverse space 247 through the reverse feed port 2435 and gradually moves into the depth of the reverse space 247. As the clump of food moves into the depth of the reverse space 247, it is gradually crushed by the reverse space 247, whose height gradually decreases, breaking the sticky structure of the clump of food.

[0307] It is understandable that the descriptions of other structures and controls with the first stirring element can be found in the above text, and need not be repeated here.

[0308] It is understandable that, for embodiments with a third stirring element, the method for controlling the disruption of clumps of food includes: Drive component 22 drives the third stirring component 27 to rotate; The multiple impact parts 2722 of the third stirring element 27 impact the clump of food during the movement and break the sticky structure of the clump of food. After the food clumps whose adhesive structure has been broken down by the impact are decomposed into small particles, they are sent out through the material passage gap 2723 of the third mixing element 27.

[0309] It is understandable that the descriptions of other structures and controls with a third stirring element can be found in the above text, and need not be repeated here.

[0310] It is understood that, for embodiments with a second stirring element, the control method further includes: during the process of the rotating component 23 driving the plurality of stirring elements to rotate around the rotation axis, and the driving component 22 driving the stirring elements to rotate around the rotation axis, the driving component 22 drives the second stirring element 25 to rotate around the second rotation axis, and the stirring part of the second stirring element 25 pushes against the food in the pot body 1 to achieve stirring.

[0311] It is understandable that the descriptions of other structures and controls with a second stirring element can be found in the above text, and need not be repeated here.

[0312] For example, for a cooking appliance having a first stirring element and a second stirring element, the control method includes: The control drive assembly 22 drives the rotating assembly 23 to rotate around the rotation axis, thereby causing the first and second stirring components, which are rotatably mounted on the drive assembly 22, to rotate around the rotation axis.

[0313] At the same time, the drive assembly 22 drives the first stirring element to rotate around its rotation axis, and the drive assembly 22 drives the second stirring element to rotate around its rotation axis.

[0314] The inlet 2425 and the extrusion space 246 formed between the first stirring part 242 and the inner wall 11 of the pot body 1 move together. The clumps of food located on the movement path are collected into the extrusion space 246 through the inlet 2425 and gradually move into the depth of the extrusion space 246. As the clumps of food move into the depth of the extrusion space 246, the adhesive structure of the clumps of food is gradually broken by the extrusion space 246, whose extrusion height gradually decreases. After the clumps of food whose adhesive structure has been broken by the extrusion space 246 are decomposed into fine particles, they are sent out from the discharge gap 2426.

[0315] At the same time, the stirring part of the second stirring component 25 pushes and drives the food inside the pot body 1 to tumble and stir.

[0316] For example, for a cooking appliance with a second and a third mixing element, the control method includes: The control drive assembly 22 drives the rotating assembly 23 to rotate around the rotation axis, thereby causing the third and second stirring components, which are rotatably mounted on the drive assembly 22, to rotate around the rotation axis.

[0317] At the same time, the drive assembly 22 drives the third stirring element to rotate around its rotation axis, and the drive assembly 22 drives the second stirring element to rotate around its rotation axis.

[0318] During the movement of the third agitator 27, the multiple impact parts 2722 impact the clump of food and break the adhesive structure of the clump of food. After the clump of food with the adhesive structure broken by the impact decomposes into fine particles, it is sent out from the material passage gap 2723 of the third agitator 27.

[0319] At the same time, the stirring part of the second stirring component 25 pushes and drives the food inside the pot body 1 to tumble and stir.

[0320] For example, for a cooking appliance having a first stirring element, a second stirring element, and a third stirring element, the control method includes: The control drive assembly 22 drives the rotating assembly 23 to rotate around the rotation axis, thereby causing the first stirring element, the second stirring element, and the third stirring element, which are rotatably mounted on the drive assembly 22, to rotate around the rotation axis.

[0321] At the same time, the drive assembly 22 drives the first stirring element, the second stirring element and the third stirring element to rotate around their respective rotation axes.

[0322] The inlet 2425 and the extrusion space 246 formed between the first stirring part 242 and the inner wall 11 of the pot body 1 move together. The clumps of food located on the movement path are collected into the extrusion space 246 through the inlet 2425 and gradually move into the depth of the extrusion space 246. As the clumps of food move into the depth of the extrusion space 246, the adhesive structure of the clumps of food is gradually broken by the extrusion space 246, whose extrusion height gradually decreases. After the clumps of food whose adhesive structure has been broken by the extrusion space 246 are decomposed into fine particles, they are sent out from the discharge gap 2426.

[0323] Meanwhile, the multiple impact parts 2722 of the third agitator 27 impact the clump of food during the movement and break the sticky structure of the clump of food; after the clump of food whose sticky structure has been broken by impact is decomposed into fine particles, it is sent out from the material passage gap 2723 of the third agitator 27.

[0324] At the same time, the stirring part of the second stirring component 25 pushes and drives the food inside the pot body 1 to tumble and stir.

[0325] In some alternative embodiments, during cooking, the rotating component 23 rotates at a speed of less than or equal to 100 r / min, and the stirring component rotates at a speed of less than or equal to 400 r / min.

[0326] It is understandable that the rotation speed of the rotating component 23 does not exceed 100 r / min, which can reduce the rotational inertia of the overall mechanism and avoid food splashing caused by high-speed swinging.

[0327] It is understandable that the stirring speed is controlled within 400r / min, which can smoothly knead and impact clumps of food without tearing the food due to excessive speed. At the same time, the stable speed makes it easy for the stirring structure to fully squeeze and break up the clumps of food formed during the stirring process.

[0328] In some alternative embodiments, the control method includes a first cooking stage.

[0329] Optionally, in the first cooking stage, the control drive assembly 22 drives the rotating assembly 23 to rotate around the rotation axis at a first speed, so as to drive the multiple stirring pieces rotatably mounted on the drive assembly 22 to rotate; and the control drive assembly 22 drives all the stirring pieces to rotate around the rotation axis within the first speed range, so as to drive the stirring part of the stirring pieces to rotate and stir the food.

[0330] It should be noted that during the first cooking stage, the rotation speed of each stirring component can be the same or different, as long as they are all kept within the first rotation speed range.

[0331] For example, in one embodiment, during the first cooking stage, the rotation speed of each stirring component is the third rotation speed.

[0332] Optionally, during the first cooking stage, the rotation speed of the stirring element gradually increases within a first rotation speed range.

[0333] Optionally, in the first cooking stage, the rotating component 23 rotates at a speed of 10 to 30 r / min, and the stirring component rotates at a speed of 80 to 150 r / min.

[0334] Optionally, the first cooking stage lasts for 20 to 40 seconds.

[0335] Optionally, the first cooking stage is the pan-warming stage.

[0336] During this stage, low-speed forward rotation allows the oil to be evenly spread across the inner wall of the pot 11, preventing localized dry burning. The low-speed operation will not cause food to splatter excessively, and the pot can be fully moistened in a short time. At this stage, you can add ingredients such as egg liquid, green onions, or ginger.

[0337] In some optional embodiments, the control method includes a second cooking stage, which is located after the first cooking stage. That is, the control method includes both a first cooking stage and a second cooking stage.

[0338] Optionally, in the second cooking stage, the control drive assembly 22 drives the rotating assembly 23 to rotate in the opposite direction around the rotation axis at a second rotation speed, so as to drive the multiple stirring pieces rotatably mounted on the drive assembly 22 to rotate in the opposite direction; and the control drive assembly 22 drives all the stirring pieces to rotate in the opposite direction around the rotation axis within the second rotation speed range, so as to drive the stirring part of the stirring piece to rotate in the opposite direction and stir the food.

[0339] It should be noted that during the second cooking stage, the reverse rotation speeds of each stirring component can be the same or different, as long as they are all controlled to rotate within the second rotation speed range.

[0340] For example, in one embodiment, during the second cooking stage, the reverse rotation speed of each stirring element is the fourth rotation speed.

[0341] Understandably, food becomes more and more evenly mixed over time. For a cooking machine, food becomes more and more cooked. By controlling the mixing components to rotate in the opposite direction after a period of time, it is beneficial to thoroughly mix the food, so that the food can be mixed evenly and heated evenly.

[0342] Optionally, the first speed can be the same as the second speed.

[0343] Optionally, the first speed is less than the second speed, so that as the food becomes more cooked or more dispersed, the stirring speed is faster, so that the food can be stirred evenly and heated evenly.

[0344] Optionally, the second speed range is greater than the first speed range, that is, the speed of all stirring components in the second cooking stage is greater than the speed of all stirring components in the first cooking stage.

[0345] Optionally, the fourth rotational speed is greater than the third rotational speed.

[0346] Optionally, in the first cooking stage, the initial rotation speed is gradually increased, so that the rotation speed can be increased as the food cooks, thereby making the stir-frying more even.

[0347] Optionally, in the second cooking stage, the rotating component 23 rotates at a speed of 40-70 r / min, and the stirring component rotates at a speed of 180-300 r / min.

[0348] Optionally, the second cooking stage may last for 90–180 seconds.

[0349] Optionally, the second cooking stage is a stir-frying and cooking stage.

[0350] In the second cooking stage, the reverse medium speed increases the frequency of food turning, fully mixes various foods, and the longer running time ensures that the food is heated evenly and cooked through. At the same time, the moderate speed can stably knead and break up clumps of food.

[0351] Optionally, in the second cooking stage, the second rotation speed is gradually increased, so that the rotation speed can be increased as the food cooks, thereby making the stir-frying more even.

[0352] Optionally, during the second cooking stage, the rotation speed of the stirring element gradually increases within the second rotation speed range.

[0353] In some alternative embodiments, the control method further includes a third cooking stage, which is located after the second cooking stage.

[0354] That is, the control method includes a first cooking stage, a second cooking stage, and a third cooking stage.

[0355] In the third cooking stage, the control drive assembly 22 drives the rotating assembly 23 to rotate around the rotation axis at a third speed, thereby driving multiple stirring pieces rotatably mounted on the drive assembly 22 to rotate; and the control drive assembly 22 drives all stirring pieces to rotate around the rotation axis within the third speed range, thereby driving the stirring part of the stirring pieces to rotate and stir the food.

[0356] Thus, in the third stage, the rotating component and the stirring element are reversed again, returning to the same rotation direction as in the first cooking stage, in order to improve the uniformity of mixing by driving the food to stir in the opposite direction again.

[0357] It should be noted that during the third cooking stage, the rotation speed of each stirring component can be the same or different, as long as they are all controlled within the third rotation speed range.

[0358] For example, in some embodiments, during the third cooking stage, the rotation speed of each stirring component is the fifth rotation speed.

[0359] In some alternative embodiments, the third rotational speed is greater than the first rotational speed and the second rotational speed; and / or, the range of the third rotational speed is greater than the range of the first rotational speed and the second rotational speed.

[0360] It is understandable that in the third cooking stage, the food may have already been cooked and is gradually entering or has entered the sauce reduction stage. At this time, the rotation speed of the rotating component and the stirring component can be increased again to avoid burning and improve the uniformity of heating.

[0361] Optionally, the third speed is greater than the second speed, and the second speed is greater than the first speed.

[0362] Optionally, the rotation speed of all mixing components in the second cooking stage is greater than that of all mixing components in the first cooking stage, and the rotation speed of all mixing components in the third cooking stage is greater than that of all mixing components in the second cooking stage.

[0363] Optionally, in the third cooking stage, the third rotation speed is gradually increased, so that the rotation speed can be increased as the food cooks, thereby making the stir-frying more even.

[0364] Optionally, in the third cooking stage, the rotation speed of the stirring element gradually increases within the third rotation speed range.

[0365] Optionally, in the third cooking stage, the rotating component 23 rotates at a speed of 75-100 r / min, and the stirring component rotates at a speed of 320-400 r / min.

[0366] Optionally, the second cooking stage may last for 15 to 40 seconds.

[0367] Optionally, the second cooking stage is the sauce reduction stage.

[0368] In the third cooking stage, high-speed stirring can quickly concentrate the broth, allowing it to evenly coat the food surface. Short-term high-speed operation can prevent the broth from drying out and causing the food to stick to the bottom.

[0369] In some alternative embodiments, the control method further includes a fourth cooking stage, which is located after the second cooking stage.

[0370] That is, the control method includes a first cooking stage, a second cooking stage, and a fourth cooking stage.

[0371] In the fourth cooking stage, the control drive assembly 22 drives the rotating assembly 23 to rotate in the opposite direction around the rotation axis at a fourth speed, so as to drive the multiple stirring pieces rotatably mounted on the drive assembly 22 to rotate; and the control drive assembly 22 drives all the stirring pieces to rotate in the opposite direction around the rotation axis within the fourth speed range, so as to drive the stirring part of the stirring piece to rotate and stir the food.

[0372] Thus, in the fourth stage, the rotating component and stirring element are controlled to not turn, maintaining the same rotation direction as in the second cooking stage.

[0373] It should be noted that in the fourth cooking stage, the rotation speed of each stirring component can be the same or different, as long as they are all controlled to rotate within the fourth rotation speed range.

[0374] For example, in some embodiments, during the fourth cooking stage, the rotation speed of each stirring component is the sixth rotation speed.

[0375] In some alternative embodiments, the fourth rotational speed is greater than the first rotational speed and the second rotational speed; and / or, the range of the fourth rotational speed is greater than the range of the first rotational speed and the second rotational speed.

[0376] It is understandable that in the fourth cooking stage, the food may have already been cooked and is gradually entering or has entered the sauce reduction stage. At this time, the rotation speed of the rotating component and the stirring component can be increased again to avoid burning and improve the uniformity of heating.

[0377] Optionally, the fourth rotational speed is greater than the second rotational speed, and the second rotational speed is greater than the first rotational speed.

[0378] Optionally, the rotation speed of all mixing components in the second cooking stage is greater than that of all mixing components in the first cooking stage, and the rotation speed of all mixing components in the fourth cooking stage is greater than that of all mixing components in the second cooking stage.

[0379] Optionally, in the fourth cooking stage, the fourth rotation speed is gradually increased, so that the rotation speed can be increased as the food cooks, thereby making the stir-frying more even.

[0380] Optionally, in the fourth cooking stage, the rotation speed of the stirring element gradually increases within the fourth rotation speed range.

[0381] Optionally, in the fourth cooking stage, the rotating component 23 rotates at a speed of 75-100 r / min, and the stirring component rotates at a speed of 320-400 r / min.

[0382] Optionally, the fourth cooking stage lasts for 15 to 40 seconds.

[0383] Optionally, the fourth cooking stage is the sauce reduction stage.

[0384] In the fourth cooking stage, high-speed stirring can quickly concentrate the broth, allowing it to evenly coat the food surface. Short-term high-speed operation can prevent the broth from drying out and causing the food to stick to the bottom.

[0385] Of course, in some embodiments, more cooking stages can be set to increase the diversity of rotary stirring, thereby improving the stirring effect.

[0386] For example, in some embodiments, the control method includes a fifth cooking stage, which is located after the first cooking stage. That is, the control method includes a first cooking stage and a fifth cooking stage.

[0387] In the fifth cooking stage, the control drive assembly (22) drives the rotating assembly (23) to rotate around the rotation axis at a second rotation speed, so as to drive the multiple stirring pieces rotatably mounted on the drive assembly (22) to rotate; and the control drive assembly (22) drives all the stirring pieces to rotate in the opposite direction around the rotation axis within the second rotation speed range, so as to drive the stirring part of the stirring piece to rotate in the opposite direction and stir the food.

[0388] It should be noted that in the fifth cooking stage, the rotation direction of the rotating component is the same as in the first stage, but the rotation direction of each stirring component is opposite to that in the first stage.

[0389] It should be noted that in the fifth cooking stage, the reverse rotation speed of each stirring component can be the same or different, as long as they are all controlled to rotate within the second speed range.

[0390] For example, in one embodiment, during the fifth cooking stage, the reverse rotation speed of each stirring element is the seventh rotation speed.

[0391] Understandably, food becomes more and more evenly mixed over time. For a cooking machine, food becomes more and more cooked. By controlling the mixing components to rotate in the opposite direction after a period of time, it is beneficial to thoroughly mix the food, so that the food can be mixed evenly and heated evenly.

[0392] Optionally, the first speed can be the same as the second speed.

[0393] Optionally, the first speed is less than the second speed, so that as the food becomes more cooked or more dispersed, the stirring speed is faster, so that the food can be stirred evenly and heated evenly.

[0394] Optionally, the second speed range is greater than the first speed range, that is, the speed of all stirring components in the fifth cooking stage is greater than the speed of all stirring components in the first cooking stage.

[0395] Optionally, the seventh rotational speed is greater than the third rotational speed.

[0396] Optionally, in the fifth cooking stage, the second rotation speed is gradually increased, so that the rotation speed can be increased as the food cooks, thereby making the stir-frying more even.

[0397] Optionally, in the fifth cooking stage, the rotating component 23 rotates at a speed of 40-70 r / min, and the stirring component rotates at a speed of 180-300 r / min.

[0398] Optionally, the fifth cooking stage may last for 90–180 seconds.

[0399] Optionally, the fifth cooking stage is the stir-frying and cooking stage.

[0400] In the fifth cooking stage, the reverse medium speed increases the frequency of food turning, fully mixes various foods, and the longer running time ensures that the food is heated evenly and cooked through. At the same time, the moderate speed can stably knead and break up clumps of food.

[0401] Optionally, in the fifth cooking stage, the second rotation speed is gradually increased, so that the rotation speed can be increased as the food cooks, thereby making the stir-frying more even.

[0402] Optionally, in the fifth cooking stage, the rotation speed of the stirring element gradually increases within the second rotation speed range.

[0403] The control method includes a sixth cooking stage, which is located after the first cooking stage. That is, the control method includes both a first cooking stage and a sixth cooking stage.

[0404] In the sixth cooking stage, the control drive assembly (22) drives the rotating assembly (23) to rotate in the opposite direction around the rotation axis at a second rotation speed, so as to drive the multiple stirring pieces rotatably mounted on the drive assembly (22) to rotate in the opposite direction; and the control drive assembly (22) drives all the stirring pieces to rotate around the rotation axis within the second rotation speed range, so as to drive the stirring part of the stirring piece to rotate and stir the food.

[0405] It should be noted that in the sixth cooking stage, the rotation direction of the rotating component is opposite to that in the first stage, but the rotation direction of each stirring component is the same as that in the first stage.

[0406] It should be noted that in the sixth cooking stage, the reverse rotation speeds of each stirring component can be the same or different, as long as they are all controlled to rotate within the second speed range.

[0407] The parameter settings for the second speed and the second speed range in the sixth cooking stage can refer to the relevant settings in the fifth cooking stage, and need not be repeated here.
