Description

Technical Field

[0001] This invention belongs to the field of automatic cooking technology, and in particular relates to an automatic cooking device and method. Background Technology

[0002] With the advancement of technology, various cooking machines have emerged in the culinary field, replacing traditional manual cooking and freeing people from the kitchen. Existing cooking machines include: a drive unit, a feeding mechanism, a cooking pot, and a cleaning mechanism. Among these, the cooking pot is used to hold and heat the ingredients, greatly influencing the final quality of the dish.

[0003] In existing rotary cooker structures, a cylindrical internal contour is commonly used. To balance the amount of food to be cooked and the evenness of heating, the curvature of the internal contour of this type of rotary cooker structure is relatively small. This allows it to accommodate a large amount of food while ensuring even heating when cooking large quantities. However, according to common cooking knowledge, many dishes require the pre-cooking of seasonings before the main ingredients, such as sautéing scallions, ginger, garlic, and chili rings. These seasoning preparation steps are completed before the main ingredients are placed in the cooker. Because the amount of seasonings is small, in order to control the sautéing temperature, the seasonings need to be gathered together during cooking to ensure the best sautéing effect. The existing rotary cooker structure only meets the needs of cooking large quantities of main ingredients, and cannot meet the needs of cooking small quantities of pre-prepared ingredients. Therefore, it cannot simultaneously meet the needs of cooking small quantities of pre-prepared ingredients and cooking large quantities of main ingredients. This is because the inner contour shape of the cooker limits the ability to gather small quantities of ingredients during cooking. The ingredients will be scattered inside the rotary cooker, which can easily cause the ingredients to be overheated, or the solid ingredients and liquid ingredients (oil, soy sauce, cooking wine, etc.) cannot be fully mixed, requiring more liquid ingredients to mix. This can easily lead to waste of liquid ingredients or excessive addition of liquid ingredients, which affects the quality of the dish. Summary of the Invention

[0004] The automatic cooking equipment provided in this invention aims to solve the problem that existing automatic cooking equipment, when cooking small or small amounts of ingredients, lacks the function of gathering small amounts of ingredients, resulting in overheating of small or small amounts of ingredients or difficulty in fully mixing solid ingredients with liquid ingredients, which easily leads to waste of liquid ingredients or excessive addition of liquid ingredients, thus affecting the quality of the dish.

[0005] The present invention is implemented as follows: an automatic cooking device is provided, comprising:

[0006] A rotary cooker for cooking ingredients includes an opening, an ingredient gathering section located at the opposite end of the opening, and an ingredient spreading section located between the opening and the ingredient gathering section.

[0007] A motion control device connected to the rotary cooker is used to control the movement of the rotary cooker during cooking, so that the ingredients are in the food gathering part or the food spreading part;

[0008] A heating device located outside the rotary kettle is used to heat the food spreading section and / or the food gathering section;

[0009] The food gathering section and the food spreading section have a smooth transition, and the stacking height of food of the same volume in the food gathering section is greater than the stacking height in the food spreading section.

[0010] This invention also provides a method for automatic cooking using the above-mentioned automatic cooking equipment, comprising the following steps:

[0011] In the feeding step, the motion control device controls the rotary kettle to rotate so that the opening faces upward, allowing the ingredients to be fed into the rotary kettle through the opening.

[0012] The heating step involves heating the food gathering section at the bottom of the rotary kettle and / or heating the food spreading section at the waist of the rotary kettle using the heating device.

[0013] In the material turning step, the motion control device controls the movement of the rotary kettle so that the ingredients inside the rotary kettle are in the material gathering part or the material spreading part.

[0014] In this embodiment of the invention, the ingredient gathering section has an ingredient gathering function. When cooking the pre-prepared ingredients for a dish, the rotary pot can be controlled to rotate to a vertical state, allowing a small amount of pre-prepared ingredients to gather on the ingredient gathering section. This ensures that the ingredients and seasonings are fully mixed for pre-cooking, improving the cooking quality of the ingredients. When cooking the main ingredients of a dish, the rotary pot can be controlled to rotate to a horizontal state, allowing a large amount of main ingredients to be spread out on the ingredient spreading section for cooking. This ensures that the ingredients are fully heated or turned, guaranteeing the overall cooking quality of the dish. The heating device covers the periphery of the ingredient spreading section and the ingredient gathering section, enabling zoned heating. The ingredient spreading section and the ingredient gathering section can be heated individually or simultaneously according to different cooking needs, providing a variety of cooking techniques.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] This invention involves spreading ingredients out in the food spreading section of a rotary cooker and gathering them in the food gathering section. When there are few ingredients, they can be gathered in the food gathering section of the rotary cooker for cooking, allowing the ingredients to mix thoroughly. When there are many ingredients, they can be spread out in the food spreading section of the rotary cooker for cooking, allowing the ingredients to be fully heated or turned, thus ensuring the quality of the dish.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides an automatic cooking device, which includes a rotary pot 100 for cooking ingredients, including an opening 101, an ingredient gathering part 103 located at the opposite end of the opening 100, and an ingredient spreading part 102 located between the opening 101 and the ingredient gathering part 103. The ingredient gathering part 103 and the ingredient spreading part 102 are smoothly connected and transitioned, wherein the stacking height of ingredients of the same volume in the ingredient gathering part 103 is greater than the stacking height in the ingredient spreading part 102.

[0040] The inner diameter of the opening 101 is smaller than any inner diameter of the food spreading section 102, resulting in a constricted shape at the top of the inner cavity. The inner cavity of the rotary kettle 100 is curved; for example, both the food spreading section 102 and the food gathering section 103 are curved, and there is a smooth transition between them. This makes the inner cavity of the rotary kettle smooth, which facilitates the sliding of food between the food spreading section 102 and the food gathering section 103.

[0041] The smooth transition between the food spreading section 102 and the food gathering section 103 can be understood as the connection point 108 between them having no abrupt inflection point, or as the curved surfaces of the food spreading section and the food gathering section being tangent at the connection point 108. The connection point 108 divides the inner cavity of the rotary kettle into the food spreading section 102 and the food gathering section 103.

[0042] The aforementioned curve can be rotated around the rotation axis 104 to obtain the corresponding food spreading surface or food gathering surface. The food spreading surface and the food gathering surface can be obtained by rotating around the rotation axis 104 using curves of the same type but different size parameters, or by rotating around the rotation axis 104 using curves of different types. For example, the aforementioned curve type can be a circular arc or an elliptical arc.

[0043] The reason why the ingredients can be gathered at the ingredient gathering part 103 and spread out at the ingredient spreading part 102 is that, if the ingredient volume measurement method is used, such as... Figure 17 , Figure 18 As shown, the first food accumulation height H1 of food of the same volume piled on the food gathering part 103 is greater than the second food accumulation height H2 of food piled on the food spreading part 102; as Figure 19 As shown, this allows even small amounts of ingredients to be gathered on the ingredient gathering part 103, which is beneficial for cooking the ingredients. This is especially true when cooking certain dishes that require pre-cooking of some ingredients. The ingredients used are few, such as five chili rings that need to be stir-fried. This would not be possible to cook them in a place that does not have a gathering function. Since the ingredient gathering part 103 has a gathering function, it can gather the five chili rings together, allowing stir-frying to be completed with a small amount of oil.

[0044] It should be noted that the cooking mentioned above includes cooking for various purposes such as manual cooking, restaurant cooking, and industrial cooking. The rotary cooker mentioned above can be used in cooking environments such as homes, restaurants, canteens, and factory food processing. The automatic cooking equipment mentioned above can be used to cook cooked food as well as to cook cold dishes.

[0045] The automatic cooking equipment also includes a motion control device (not shown in the figure) connected to the rotary pot 100, used to control the movement of the rotary pot 100 during the cooking process, so that the ingredients are in the ingredient gathering part 103 or the ingredient spreading part 102. Specifically, during the cooking process, the rotary pot 100 is controlled to rotate between vertical (the rotation axis 4 of the rotary pot 100 is in a vertical state) and horizontal (the rotation axis 4 of the rotary pot 100 is in a horizontal state), so that the ingredients dynamically change between the gathered state and the spreading state.

[0046] The automatic cooking equipment further includes a heating device (not shown in the figure) located outside the rotary pot, used to heat the food spreading part and / or the food gathering part. Specifically, the heating device can cover the periphery of the food spreading part 103 and the food gathering part 102 to heat the food spreading part 103 and the food gathering part 102 respectively.

[0047] Combination Figure 19 and Figure 20 As shown, since ingredients can be spread out for cooking on the ingredient spreading section 102 of the rotary cooker 100, and can also be gathered for cooking on the ingredient gathering section 103, the rotary cooker 100 can be controlled to rotate between vertical and horizontal movements during cooking, allowing the ingredients to switch between the ingredient spreading section 102 and the ingredient gathering section 103, thus achieving both spreading and gathering of the ingredients. This provides a variety of cooking techniques and can more realistically simulate manual cooking methods. Furthermore, the ingredient gathering section 103 has an ingredient gathering function, which can be used when cooking the pre-prepared ingredients for the dish. Controlling the rotary cooker 100 to rotate to a vertical position allows small amounts of pre-prepared ingredients to gather on the ingredient gathering section 103, facilitating precise addition of solid and liquid ingredients according to the recipe. The ingredient gathering section 103 of the rotary cooker gathers these ingredients and seasonings for thorough mixing and pre-cooking, improving the cooking quality of the ingredients. When cooking the main ingredients of the dish, the rotary cooker 100 can be rotated to a horizontal position, allowing large amounts of main ingredients to spread out on the ingredient spreading section 102 for cooking, ensuring that the ingredients are fully heated or turned, and guaranteeing the overall cooking quality of the dish.

[0048] The heating device covers the periphery of the food spreading section 103 and the food gathering section 102, enabling zone heating. It can heat the food spreading section 102 and the food gathering section 103 individually or simultaneously according to different cooking needs, providing a variety of cooking techniques.

[0049] Example 2

[0050] Combination Figure 1 and Figure 3As shown, based on Embodiment 1, in this embodiment, the automatic cooking device further includes: a housing assembly 150, a first drive shaft 111 connected to the housing assembly 150, and a first drive device 110 connected to the first drive shaft 111; the rotary pot 100 is rotatably disposed within the housing assembly 150, the first drive shaft 111 is intersected with the rotation axis of the rotary pot 100, and the first drive device 110 drives the rotary pot to rotate around the first drive shaft 111.

[0051] The rotary vessel 100 is radially fixed by the housing assembly 150, thereby enabling the rotary vessel 100 to be radially driven by the first drive shaft 111 and thus achieving the rotation of the rotary vessel 100.

[0052] Example 3

[0053] like Figure 4 As shown, based on Embodiment 2, the automatic cooking device further includes a second driving device 120 disposed within the housing assembly 150. The second driving device 120 drives the rotary pot 100 to rotate around its own rotation axis. By controlling the rotation of the rotary pot 100 through the second driving device 120 disposed within the housing assembly 150, the second driving device 120 is not affected by the placement of the first driving device 110. The two independently control the movement of the rotary pot without interfering with each other.

[0054] Furthermore, such as Figure 4 As shown, a top cover 152 and a first bottom cover 153 are respectively provided at both ends of the housing assembly. The top cover 152 and the first bottom cover 153 are respectively provided with support parts (not shown in the figure) for supporting the opening end and the bottom end of the rotary vessel 100.

[0055] The rotary vessel 100 is supported and installed by the support parts on the top cover 152 and the first bottom cover 153, so that the installation process can be carried out from both ends of the shell assembly 150, which facilitates assembly.

[0056] Meanwhile, in this embodiment, the top cover 152 and the first bottom cover 153 are connected by multiple support rods 151, which can improve the overall structural rigidity of the shell assembly, thereby ensuring that the shell assembly 150 can support the rotating rotary vessel 100 and provide sufficient strength to overturn the rotary vessel 100.

[0057] Furthermore, such as Figure 5As shown, the rotary vessel 100 has a connecting neck 1019 at its open end, and the rotary vessel 100 is connected to the top cover 152 through the connecting neck 1019; the bottom end of the rotary vessel 100 is provided with a convex shaft (not shown in the figure) fixed to the rotary vessel 100, and a bearing (not shown in the figure) is provided on the first bottom cover 153 and connected to the convex shaft, and the convex shaft is connected to the second drive device 120 for transmission.

[0058] Specifically, the cam shaft can be directly connected to the bearing to fix its axial direction on the first bottom cover 153, and then connected to the second drive device 120 via a coupling. Alternatively, the output shaft of the second drive device 120 can be fixed on the bearing and then connected to the cam shaft via a coupling.

[0059] In this embodiment, the convex shaft can be integrally formed with the bottom end of the rotary kettle 100, or it can be connected in a detachable manner.

[0060] By setting a connecting neck 1019 and a convex shaft at the open end and bottom end of the rotary vessel 100 respectively, the rotation drive of the rotary vessel 100 is realized.

[0061] Furthermore, the connecting neck 1019 is also provided with an outer sleeve 154, an inner liner 155, a sealing ring 156, and an end cap 157, which can ensure that the connection between the connecting neck 1019 and the top cover 152 remains sealed while the rotary vessel 100 rotates relative to the top cover 152.

[0062] Furthermore, such as Figure 4 and Figure 5 As shown, the automatic cooking equipment also includes a second drive unit 120 and a belt drive unit 121 connected to the cam shaft drive. Specifically, the cam shaft is connected to the driven pulley output shaft 122 of the belt drive unit 121. The housing assembly is also provided with a second bottom cover 154 for supporting the driven pulley output shaft 122 and improving operational stability.

[0063] Using belt drive is advantageous for arranging the transmission structure within a limited space, avoiding an excessively long overall structure that would be detrimental to the rotation drive of the rotary vessel.

[0064] Furthermore, such as Figure 4 As shown, the second drive device 120 is disposed on one side of the rotary vessel 100, and the output shaft (not shown in the figure) of the second drive device 120 is arranged parallel to the cam shaft. In this way, the rotary vessel 100 can be driven to rotate by the belt drive device 121.

[0065] By placing the second drive unit 120 on one side of the rotary vessel 100, the axial structural requirements are minimized, and the internal space of the housing assembly 150 can be fully utilized for arrangement.

[0066] Example 4

[0067] like Figure 1 and Figure 16 As shown, based on any of the above embodiments, the automatic cooking device further includes: a scraper assembly disposed outside the rotary pot 100, the scraper assembly including a scraper 134 and a third drive device 130, the third drive device 130 driving the scraper 134 to rotate around a set point 106 outside the rotary pot 100, so that the part of the scraper 134 in contact with the inner wall of the rotary pot 100 reciprocates between the opening 101 and the bottom of the rotary pot 100.

[0068] The purpose of the scraper assembly is to allow the scraper 134 to reciprocate between the opening 101 and the bottom of the rotary kettle 100 by moving back and forth between the inner wall of the rotary kettle 100 and the opening 101, thereby stirring the food located on the food spreading section 102 or the food gathering section 103, which can improve the mixing uniformity and heating uniformity of the food. Since the scraper assembly is set outside the rotary kettle 100, the scraper 134 swings around a set point 106 outside the rotary kettle 100 and enters the kettle body. The design of the internal contour shape of the rotary kettle 100, while taking into account the functions of gathering and spreading the food, also needs to ensure that the part of the scraper 134 that contacts the inner wall of the rotary kettle 100 can smoothly reciprocate between the opening 101 and the bottom of the rotary kettle 100. Therefore, the contours of the food spreading section 102 and the food gathering section 103 are both set as smooth curves, so that the scraper 134 can move back and forth along the wall from the opening direction of the rotary kettle 100 to stir the food, thereby improving the mixing uniformity and heating uniformity of the food.

[0069] The scraper 134 has certain elastic deformation characteristics. The contact method between the scraper 134 and the inner wall of the rotary kettle 100 can be interference contact to ensure that the scraper 134 and the inner wall of the rotary kettle 100 are always in effective contact to stir the food on the food spreading part 102 or the food gathering part 103.

[0070] Example 5

[0071] Based on Embodiment 4, the set point 106 is located on the extension line of the waist diameter (the waist diameter refers to the diameter of the largest cross-sectional circle perpendicular to the rotation axis 4 on the inner contour of the food spreading part 102 of the rotary kettle 100). The purpose of this setting is to enable the scraper 134 to swing around the set point 106 and sweep the trajectory to completely cover the entire inner wall contour of the rotary kettle 100 with a shorter path, ensuring that the scraper 134 can smoothly reciprocate between the opening and the bottom of the rotary kettle 100 after entering the kettle body.

[0072] Specifically, the scraper 134 is mounted on the output shaft of the third drive device 130. The axis of the output shaft of the third drive device 130 intersects the extension line of the waist diameter 107 of the food spreading part 102 of the rotary pot 100. The set point 106 is the intersection of the two lines. The third drive device 130 drives the scraper 134 to swing around the set point 106, so that the part of the scraper 134 in contact with the inner wall of the rotary pot 100 reciprocates between the opening of the rotary pot 100 and the bottom of the rotary pot 100.

[0073] In this embodiment, due to the special design of the internal contour shape of the rotary cooker 100, the scraper 134 can reciprocate along the wall inside the rotary cooker 100 to turn the ingredients, making them even and improving the cooking quality of the dish. At the same time, the rotary cooker 100 has the functions of spreading the ingredients in the ingredient spreading part 102 and gathering the ingredients in the ingredient gathering part 103. Therefore, when there are few ingredients, they can be gathered in the ingredient gathering part 103 of the rotary cooker 100 for cooking, so that the ingredients are fully mixed. When there are many ingredients, they can be spread in the ingredient spreading part 102 of the rotary cooker 100 for cooking, so that the ingredients are fully heated or turned, ensuring the quality of the dishes produced by the automatic cooking machine.

[0074] Example 6

[0075] like Figure 2 As shown, based on Embodiment 1, the internal contours of the food spreading portion 102 and the food gathering portion 103 of the rotary kettle 100 are both smooth curves in the axial cross-section of the rotary kettle 100. This facilitates the stirring of food inside the rotary kettle 100 by a scraper. The smooth curves of the internal contours of the food spreading portion 102 and the food gathering portion 103 in the axial cross-section of the rotary kettle can be understood as the connection point 108 between the food spreading portion 102 and the food gathering portion 103 having no sharp inflection point, or as the curved surfaces of the food spreading portion and the food gathering portion being tangent at the connection point 108. The connection point 108 divides the inner cavity of the rotary kettle into the food spreading portion 102 and the food gathering portion 103.

[0076] The aforementioned axial section can be understood as the plane where the rotation axis 104 is located. For ease of understanding of the present invention, the outline obtained by projecting the inner contour of the rotary kettle onto the plane where the rotation axis 104 is located is used for explanation. At this time, the opening 101 of the rotary kettle is a straight line, the food spreading part 102 is two corresponding smooth curves, and the food gathering part 103 is a smooth curve. The smooth curves of the food spreading part 102 and the smooth curves of the food gathering part 103 are smoothly connected. The aforementioned smooth connection can be understood as the smooth curves of the food spreading part 102 and the smooth curves of the food gathering part 103 being tangent at the connection point 108. In this way, there will be no sharp inflection point at the connection point 108 between the food spreading part 102 and the food gathering part 103.

[0077] The food spreading section 102 inside the rotary kettle 100 can be formed by rotating the smooth curve of the food spreading section 360 degrees around the rotation axis 104. Similarly, the food gathering section 103 inside the rotary kettle 100 can also be formed by rotating the smooth curve of the food gathering section 103 360 degrees around the rotation axis 104. It is worth noting that after the smooth curves of the food spreading section 102 and the food gathering section 103 are smoothly connected, the internal contours of the food spreading section 102 and the food gathering section 103 as a whole form a smooth curve. This smooth curve, rotating 360 degrees around the rotation axis 104, forms the entire inner surface of the rotary kettle 100.

[0078] In this embodiment of the invention, since the ingredients are spread out on the ingredient spreading part 102 of the rotary pot 100 and gathered on the ingredient gathering part 103 of the rotary pot, both the ingredient spreading part 102 and the ingredient gathering part 103 are curved surfaces after smooth curve rotation, and there are no corners after the two are smoothly connected, the movement of the ingredients can be smoother when the position of the rotary pot 100 changes. At the same time, when there are few ingredients, they can be gathered on the ingredient gathering part 103 of the rotary pot 100 for cooking, so that the ingredients are fully mixed. When there are many ingredients, they can be spread out on the ingredient spreading part 102 of the rotary pot 100 for cooking, so that the ingredients are fully heated or turned, ensuring the quality of the dish. Optionally, the smooth curve mentioned above can be an arc curve, wherein the arc curve can be a circular arc and / or an elliptical arc. For example, the smooth curve of the food spreading part 102 can be a circular arc or an elliptical arc, and the smooth curve of the food gathering part 103 can also be a circular arc or an elliptical arc. Thus, it can be concluded that the contour shape of the inner cavity of the rotary kettle 100 can be any combination of circular arcs, circular arcs and elliptical arcs, or elliptical arcs and elliptical arcs.

[0079] like Figure 2 As shown, in this embodiment, the inner contour of the food spreading part 102 on the axial section of the rotary kettle 100 is an arc, and the inner contour of the food gathering part 103 on the axial section of the rotary kettle 100 is an arc or an elliptical arc.

[0080] When the inner contour of the food gathering part 103 on the axial section of the rotary kettle 100 is an elliptical arc, the major axis of the elliptical arc coincides with the rotation axis 104 of the rotary kettle 100.

[0081] The curvature of the inner contour of the food spreading portion 102 is less than the curvature of the inner contour of the food gathering portion 103.

[0082] In one alternative implementation, please refer to Figure 7 The inner contours of the food spreading section 102 and the food gathering section 103 of the rotary kettle 100 on the axial section of the rotary kettle are circular arcs, that is, the smooth curves of the food spreading section 102 and the food gathering section 103 are both circular arcs. Specifically, since the curvature of a circle is fixed and it is easy to process, it is a better choice as the processing curve of the rotary kettle 100. However, using the entire circle (or two parts of two identical circles joined together) as the inner cavity outline of the rotary kettle 100 can lead to problems such as the scraper not easily entering the inner cavity of the rotary kettle 100, or not being able to move well along the inner cavity wall after entering the inner cavity of the rotary kettle 100. Furthermore, using the entire circle (or two parts of two identical circles joined together) as the inner cavity outline of the rotary kettle 100 results in a uniform curvature of the inner cavity, making it impossible to distinguish between the food spreading part 102 and the food gathering part 103, which may lead to problems such as the food not being able to spread out or gather. Therefore, the curved surface of the entire circle (or two parts of two identical circles joined together) is not ideal as the inner cavity outline of the rotary kettle.

[0083] The inner cavity contour of the rotary kettle 100 can be formed by taking a portion of each of two different circles. For example, take the arc of the food spreading part 102 from one circle and the arc of the food gathering part 103 from the other circle. Smoothly connect the arc of the food spreading part 102 and the arc of the food gathering part 103 to obtain the inner cavity contour of the rotary kettle 100.

[0084] Please refer to Figure 6 The two different circles mentioned above can be understood as two circles with different curvatures. In order to ensure that the scraper 134 can smoothly perform reciprocating motion against the wall inside the pot, and to ensure that the food spreading part has the function of spreading the food and the food gathering part has the function of gathering the food, the curvature of the inner contour of the food spreading part can be less than the curvature of the inner contour of the food gathering part. That is, the curvature of the arc of the food spreading part 102 is less than the curvature of the arc of the food gathering part 103. After the arc of the food spreading part 102 and the arc of the food gathering part 103 are connected, the inner contour curve of the rotary pot 100 is obtained. The inner contour curve of the rotary pot 100 is obtained by rotating 360 degrees around the rotation axis 104.

[0085] Since both the curves of the food spreading section 102 and the food gathering section 103 are arcs, in order to allow the food to be spread out for cooking on the food spreading section and gathered for cooking on the food gathering section 103, the arc of the food spreading section 102 adopts an arc with a smaller curvature, while the arc of the food gathering section 103 adopts an arc with a larger curvature. That is, the curvature of the arc of the food gathering section 103 of the rotary kettle 100 is greater than the curvature of the arc of the food spreading section 102. Therefore, the rotary kettle 100 can achieve the following: when the amount of food is small, it can be gathered on the food gathering section 103 of the rotary kettle 100 for cooking, so that the food is fully mixed; when the amount of food is large, it can be spread out on the food spreading section 102 of the rotary kettle 100 for cooking, so that the food is fully heated or turned, ensuring the quality of the dish.

[0086] In one alternative implementation, please refer to Figure 11 The inner contour of the food spreading part 102 of the rotary kettle 100 in the axial section of the rotary kettle 100 is an arc, that is, the smooth curve of the food spreading part 102 is an arc; the inner contour of the food gathering part 103 of the rotary kettle 100 in the axial section of the rotary kettle 100 is an elliptical arc, that is, the smooth curve of the food gathering part 103 is an elliptical arc; wherein, the major axis of the elliptical arc coincides with the rotation axis of the rotary kettle.

[0087] Specifically, since the curvature of a circle is fixed and the curve is closed, it is easy to process and is a preferred choice for the curve of the food spreading section 102 of the rotary kettle 100. For example, an arc of the food spreading section 102 can be extracted from one of the circles, and an elliptical arc with opposite minor axes can be extracted from an ellipse as the elliptical arc of the food gathering section 103. By smoothly connecting the arc of the food spreading section 102 and the elliptical arc of the food gathering section 103, the internal contour of the rotary kettle 100 can be obtained. The major axis of the elliptical arc coincides with the rotation axis 104 of the rotary kettle 100. Because the major axis coincides with the rotation axis 104 of the rotary kettle 100, the average curvature of the elliptical arc segment that serves as the smooth curve of the food gathering section is greater than the curvature of the circular arc, which can improve the gathering effect of the elliptical arc.

[0088] Example 7

[0089] Please see Figures 6 to 10 Based on Example 6, the ratio of the waist diameter 107 to the waist edge diameter 105 of the food spreading portion 102 is 0.4-0.9.

[0090] The ratio of the inner diameter of the opening 101 to the waist diameter 107 is 0.3-0.9;

[0091] The ratio of the diameter of the circle at the connection point 108 between the inner contour of the food spreading part 102 and the inner contour of the food gathering part 103 to the waist diameter 107 is 0.3-0.9.

[0092] Wherein, the waist diameter 107 is the diameter of the largest cross-sectional circle perpendicular to the rotation axis 104 on the inner contour of the food spreading part 102;

[0093] The waist diameter 105 is the radius of the inner contour of the cross section of the food spreading part 102 passing through the rotation axis 104;

[0094] The waist diameter 107 is smaller than the waist edge diameter 105.

[0095] To ensure that the inner cavity of the rotary cooker 100 simultaneously fulfills the functions of spreading and gathering food for cooking, and that the scraper 134 can reciprocate within the rotary cooker while adhering to the inner wall, the ratio of the waist diameter 207 to the waist edge diameter 105 of the food spreading section can be 0.4-0.9; to ensure that the opening of the rotary cooker 100 forms a constricted shape, the ratio of the inner diameter of the opening 101 to the waist diameter 107 can be 0.3-0.9; to ensure that the food can be fully spread in the food spreading section 102, the ratio of the diameter of the circle at the connection point 108 between the inner contour of the food gathering section 103 and the inner contour of the food spreading section 102 to the waist diameter 107 can be 0.3-0.9; the waist diameter 107 is the diameter of the largest cross-sectional circle perpendicular to the rotation axis 104 on the inner contour of the food spreading section 102; the waist edge diameter 105 is the radius of the arc of the inner contour of the food spreading section 102.

[0096] Specifically, when the ratio of the inner diameter of the opening 101 of the rotary cooker to the waist diameter 107 of the food spreading section 102 reaches 0.9, the opening 101 of the rotary cooker 100 is too large, and the food is easy to spill out during cooking. Moreover, the food is not easy to collect in the turnover box during turnover. Therefore, the ratio of the inner diameter of the opening 101 of the rotary cooker 100 to the waist diameter 107 of the food spreading section 102 should not exceed 0.9.

[0097] Finding the minimum ratio of the inner diameter of the opening 101 of the rotary cooker 100 to the waist diameter 107 of the food spreading section 102 involves: when the horizontal axis 1010 of the scraper can be inserted into the notch of the rotary cooker opening, the scraper 134 should still have cooking value. The contact point 1011 between the scraper 134 and the rotary cooker 100 should be below the waist diameter 107 of the food spreading section 102 of the rotary cooker. Therefore, the contact point 1011 between the scraper 134 and the rotary cooker 100 is the limit contact point 1012 of the scraper 134 on the waist diameter 107. Connect any point on the rotary cooker 100 corresponding to the waist diameter 107 to this limit contact point. Point 1012 is used to obtain a limit connecting line 1014. With the set point 106 as the center, the tangent circle 1017 of the limit connecting line 1014 is drawn. The tangent circle 1017 intersects the contour curve on the other side of the rotary vessel 100. When the distance from the other end point 1013 of the limit connecting line 1014 to the waist diameter 107 is equal to the distance from the intersection point of the tangent circle and the rotary vessel 100 to the waist diameter 107, connecting these two points is the minimum opening of the rotary vessel 100. The value corresponding to the inner diameter of this opening 101 is the minimum value at which the scraper 134 can exit the rotary vessel 100 below the waist diameter 107.

[0098] Based on the above method, the minimum ratio of the inner diameter of the opening 101 of the rotary kettle 100 to the waist diameter 107 of the food spreading section 102 is calculated under the conditions that the ratio of the waist diameter 107 to the waist edge diameter 105 is other values, and the ratio of the distance 109 from the set point 106 to the edge point of the waist diameter 107 to the waist diameter 107 is other values. After data simulation, the minimum ratio of the inner diameter of the opening 101 of the rotary kettle 100 to the waist diameter 107 of the food spreading section 102 is 0.3. If this ratio is less than 0.3, the movement of the scraper 134 in the rotary kettle 100 is greatly restricted, and it is not easy to turn the food in the rotary kettle 100.

[0099] The maximum interference fit between the scraper 134 and the inner wall of the rotary vessel 100 is the condition for the scraper 134 to enter the rotary vessel 100. The distance from the lowest contact point 1016 of the scraper 134 to the set point 106 of the scraper 134 is used as the radius. A circle is drawn with the set point 106 as the center; this circle represents the movement trajectory 1018 of the scraper 134. The movement trajectory 1018... Figure 9 , Figure 10 The movement trajectory 1018 of the scraper is represented by a dashed circle. Then, the farthest distance from the outer edge of the rotary kettle 100 to the outer edge of the rotary kettle 100 is measured. The ratio of this distance to the waist diameter 107 is the maximum interference fit between the scraper and the rotary kettle 100. The interference fit between the scraper and the rotary kettle 100 makes the food inside the rotary kettle 100 turn over better, and it is less likely that there will be food residue on the inner wall of the rotary kettle 100 after the scraper has scraped 134.

[0100] When the ratio of waist diameter 107 to waist edge diameter 105 is 1, the scraper is placed on the edge point of waist diameter 107. When the third drive device 130 is installed at the position of the set point 106, it must occupy at least 10% of the distance space of waist diameter 107. When the scraper moves in the rotary kettle 100, the scraper and the inner cavity will not have an interference fit. In addition, the installation of the scraper's rotating shaft requires space and it is impossible to install it on the edge of waist diameter 107 of the rotary kettle 100. When the set point 106 is installed outside the edge point of waist diameter 107 and the center point of waist edge diameter 105, the scraper 134 either cannot enter the rotary kettle 100 or only has one point of contact with the inner wall of the rotary kettle after entering the rotary kettle 100, which is not conducive to the reciprocating stir-frying of food.

[0101] When the ratio of waist diameter 107 to waist edge diameter 105 is 0.9, the third drive device 130 that drives the scraper 134 to reciprocate must occupy at least 10% of the distance space of waist diameter 107 when installed at set point 106. This distance space, together with waist diameter 107, occupies at least 99% of waist edge diameter 105, leaving only 1% of waist edge diameter 105 for tolerance adjustment. When the ratio of waist diameter 107 to waist edge diameter 105 is 0.2, as the ratio of the distance from set point 106 to the edge of waist diameter 107 to waist diameter 107 increases, the maximum interference of scraper 134 against the inner wall of rotary vessel 100 decreases. However, the ratio of the additional space required for scraper 134 to reciprocate to the space of rotary vessel 100 increases. That is, when the space enclosed by the dotted circle is approximately 2.1 times the space of rotary vessel, the maximum interference of scraper 134 in the inner cavity of rotary vessel 100 is 13%. Therefore, when the ratio of waist diameter 107 to waist edge diameter 105 is less than 0.3, it is not suitable to use it as the internal contour of rotary vessel 100; therefore, it is more reasonable to set the ratio of waist diameter 107 to waist edge diameter 105 in the range of 0.3-0.9.

[0102] When the ratio of the diameter of the circle at the junction 108 of the inner contour of the food gathering section 103 and the inner contour of the food spreading section 102 to the waist diameter 107 is greater than 0.9, the curved surface of the food gathering section 103 becomes too large, which is not conducive to the spreading of food in the food spreading section 102, and the gathering effect of food in the food gathering section 103 is also poor. When the ratio of the diameter of the circle at the junction 108 of the inner contour of the food gathering section and the inner contour of the food spreading section to the waist diameter 107 is less than 0.3, the area of ​​the curved surface of the food gathering section of the rotary kettle 100 becomes too small, which is not conducive to the gathering of food in the food gathering section 103. Therefore, it is more reasonable to set the ratio of the diameter of the circle at the junction 108 of the inner contour of the food gathering section 103 and the inner contour of the food spreading section 102 to the waist diameter 107 in the range of 0.3-0.9.

[0103] In this embodiment, since the ratio of the waist diameter 107 to the waist edge diameter 105 of the food spreading section 102 is 0.4-0.9, the scraper 134 can better turn the food in the pot; the ratio of the inner diameter of the opening 101 to the waist diameter 107 is 0.3-0.9, which can make the rotary pot 100 more closed and facilitate the serving of food; the ratio of the diameter of the circle at the connection point 108 between the inner contour of the food gathering section 103 and the inner contour of the food spreading section 102 to the waist diameter 107 is 0.3-0.9, which can further improve the gathering effect of the food gathering section 103; at the same time, when there is little food, it can be gathered in the food gathering section 103 of the rotary pot 100 for cooking, so that the food is fully mixed; when there is a lot of food, it can be spread out in the food spreading section 102 of the rotary pot 100 for cooking, so that the food is fully heated or turned, ensuring the quality of the dish.

[0104] Example 8

[0105] Please see Figures 6 to 10 Based on Example 7, the ratio of the waist diameter 107 to the waist edge diameter 105 of the food spreading portion 102 is 0.6-0.9.

[0106] The ratio of the inner diameter of the opening 101 to the waist diameter 107 is 0.4-0.7;

[0107] The ratio of the diameter of the circle at the connection point 108 between the inner contour of the food spreading part 102 and the inner contour of the food gathering part 103 to the waist diameter 107 is 0.5-0.8.

[0108] In this embodiment, since the ratio of the waist diameter 107 to the waist edge diameter 105 of the food spreading part 102 is 0.6-0.9, the scraper can better turn the food in the pot; the ratio of the inner diameter of the opening 101 to the waist diameter is 0.4-0.7, which can make the rotary pot 100 more closed and facilitate the serving of food; the ratio of the diameter of the circle at the connection point 108 between the inner contour of the food gathering part 103 and the inner contour of the food spreading part 102 to the waist diameter 107 is 0.5-0.8, which can further improve the gathering effect of the food gathering part 103; at the same time, when there is little food, it can be gathered in the food gathering part 103 of the rotary pot 100 for cooking, so that the food is fully mixed; when there is a lot of food, it can be spread out in the food spreading part 102 of the rotary pot 100 for cooking, so that the food is fully heated or turned, ensuring the quality of the dish.

[0109] Example 9

[0110] Please see Figures 8 to 16 In this embodiment, the inner contours of the food spreading part 102 and the food gathering part 103 on the cross section of the rotary kettle 100 through the rotation axis are both elliptical arcs; the major axis of the elliptical arc coincides with the rotation axis of the rotary kettle.

[0111] Specifically, the inner contour of the section passing through the rotation axis 104 of the rotary vessel 100 is an elliptical arc of the same ellipse;

[0112] The inner contour of the food spreading section 102 of the rotary kettle 100 is the part opposite to the end of the minor axis of the ellipse;

[0113] The inner contour of the food gathering part 103 of the rotary pot 100 is the part opposite to the end of the major axis of the ellipse.

[0114] The cross-sectional profile of the rotary kettle 100 through the rotation axis is an elliptical arc of the same ellipse; that is, the major axis of the ellipse that forms the cross-sectional profile of the rotary kettle 100 through the rotation axis 104 coincides with the rotation axis 104 of the rotary kettle 100. Alternatively, the elliptical arc of the food spreading section 102 can be understood as the elliptical arc portion opposite to the end of the major axis, and the elliptical arc of the food gathering section 103 as the elliptical arc portion opposite to the short end. After the elliptical arcs of the food spreading section 102 and the food gathering section 103 are smoothly connected, they form a partial curve on an ellipse. By rotating this curve 360 ​​degrees around the rotation axis 104, the inner cavity surface of the rotary kettle 100 can be obtained.

[0115] In this embodiment, since the internal contour curve of the rotary pot 100 is obtained on the same ellipse, the rotary pot can be made easier for production and processing. At the same time, the ingredients are spread out on the ingredient spreading part 102 of the rotary pot 100 and gathered on the ingredient gathering part 103 of the rotary pot 100. Therefore, when there are few ingredients, they can be gathered on the ingredient gathering part 103 of the rotary pot for cooking, so that the ingredients are fully mixed. When there are many ingredients, they can be spread out on the ingredient spreading part 102 of the rotary pot for cooking, so that the ingredients are fully heated or turned over, ensuring the quality of the dish.

[0116] Example 10

[0117] Please see Figures 8 to 16 Based on Example 9, the ratio of the waist diameter 107 to the waist edge diameter 105 of the rotary kettle 100 is 0.4-0.9.

[0118] The ratio of the diameter of the opening 101 to the waist diameter 107 of the rotary kettle 100 is 0.3-0.9;

[0119] The waist diameter 107 is the diameter of the largest cross-sectional circle perpendicular to the axis of rotation 104 on the inner contour of the food spreading part 102.

[0120] The waist diameter 105 is the minor axis of the elliptical arc.

[0121] Specifically, the internal contours of the food spreading section 102 and the food gathering section 103 on the cross-section of the rotary kettle 100 through the rotation axis 104 are both elliptical arcs; the major axis of the elliptical arc coincides with the rotation axis 104 of the rotary kettle 100; since the curvature of the elliptical arc is constantly changing, in order for the scraper to scrape all over the inner wall of the rotary kettle 100, the scraper and the inner wall of the rotary kettle 100 must always be in interference contact. To ensure that the scraper can be in interference fit with the inner wall of the rotary kettle 100, the ratio of the waist diameter 107 to the waist edge diameter 105 of the rotary kettle 100 is greater than or equal to 0.4 and less than 0.9. It should be noted that the specific calculation method for the above two ratios is similar to that in Example 6, and will not be repeated here.

[0122] In this embodiment, since the ratio of the waist diameter 107 to the waist edge diameter 105 of the food spreading section 102 is 0.4-0.9, the spatula can better turn the food in the pot; the ratio of the diameter of the opening 101 to the waist diameter 107 is 0.3-0.9, which can make the rotary pot 100 more effective at closing, making it easier to serve the food; thus, the gathering effect of the food gathering section 103 can be further improved; at the same time, when there is little food, it can be gathered in the food gathering section 103 of the rotary pot 100 for cooking, so that the food is fully mixed; when there is a lot of food, it can be spread out in the food spreading section 102 of the rotary pot 100 for cooking, so that the food is fully heated or turned, ensuring the quality of the dish.

[0123] Example 11

[0124] Based on Example 10, the ratio of the waist diameter 107 to the waist edge diameter 105 of the rotary kettle 100 is 0.6-0.9;

[0125] The ratio of the diameter of the opening 101 of the rotary kettle 100 to the waist diameter 107 is 0.4-0.7.

[0126] In this embodiment, since the ratio of the waist diameter 107 to the waist edge diameter 105 of the food spreading section 102 is 0.6-0.9, the spatula can better turn the food in the pot; the ratio of the diameter of the opening 101 to the waist diameter 107 is 0.4-0.7, which can make the rotary pot 100 more effective at closing, making it easier to serve the food; thus, the gathering effect of the food gathering section 103 can be further improved; at the same time, when there is little food, it can be gathered in the food gathering section 103 of the rotary pot 100 for cooking, so that the food is fully mixed; when there is a lot of food, it can be spread out in the food spreading section 102 of the rotary pot 100 for cooking, so that the food is fully heated or turned, ensuring the quality of the dish.

[0127] Example 12

[0128] like Figure 4As shown, based on Embodiment 1, the heating device can be an inductor (141, 142) respectively disposed around the food spreading section 102 and the food gathering section 103. The heating device covers the periphery of the food spreading section 102 and the food gathering section 103, which can realize the function of zone heating. The food spreading section and the food gathering section can be heated individually or simultaneously according to different cooking needs, so as to provide a variety of cooking techniques.

[0129] In addition, the inductive heating method can avoid direct contact with the rotary vessel 100, thereby avoiding the influence of the rotation of the rotary vessel 100 on the heating device.

[0130] Example 13

[0131] Based on the above embodiments, this application also provides a method for automatic cooking using the above-mentioned automatic cooking equipment, which includes the following steps:

[0132] In the feeding step, the motion control device controls the rotary kettle to rotate so that the opening faces upward, allowing the ingredients to be fed into the rotary kettle through the opening.

[0133] The heating step involves heating the food gathering section at the bottom of the rotary kettle and / or heating the food spreading section at the waist of the rotary kettle using the heating device.

[0134] In the material turning step, the motion control device controls the movement of the rotary kettle so that the ingredients inside the rotary kettle are positioned in the material gathering section or the material spreading section.

[0135] Example 14

[0136] Based on Embodiment Thirteen, the automatic cooking device further includes a second drive device for driving the rotary pot to rotate; the method further includes:

[0137] The tossing and stir-frying step involves using a second drive device to control the rotary pot, which is in a horizontal state, to reciprocate and toss the ingredients for stir-frying.

[0138] The general cooking process involves adding ingredients, preheating, frying and blanching, sautéing with seasonings, repeated stir-frying, and serving.

[0139] The rotary cooker control actions described above are accomplished by a motion control device executing a pre-imported or stored electronic recipe (control program) to control the rotary cooker's operation. The following are examples of the specific execution processes for several cooking actions:

[0140] Taking the feeding action as an example, the motion control device executes the command to control the first drive device to drive the rotary kettle to rotate, so that the opening of the rotary kettle faces upward and approaches the feeding device, so that the feeding device can smoothly put the ingredients into the kettle.

[0141] Taking the preheating action as an example, the motion control device executes commands to control the heating device to operate, thereby controlling the power and working time of the inductor according to different control parameters to achieve the required heating effect. During the blanching action, the motion control device issues commands to control the heating device to operate, thereby controlling the power and working time of the inductor to match the heating temperature and time required for blanching. Simultaneously, the motion control device executes commands to control the first drive device to drive the rotary pot to reciprocate, causing the ingredients to spread out or gather, achieving the purpose of turning the ingredients. The motion control device executes commands to control the second drive device to drive the rotary pot to reciprocate (rotate) to achieve mixing of the ingredients. The motion control device executes commands to control the third drive device to drive the scraper to reciprocate along the inner wall of the pot to achieve stirring and mixing of the ingredients. After the above actions complete a specified cycle, the heating device, the second drive device, and the third drive device stop working, and the first drive device drives the rotary pot to rotate to an opening-down position to pour the ingredients into a transfer device for turnover.

[0142] Taking the stir-frying action as an example, the motion control device executes control commands to control the first drive device to drive the rotary pot to rotate to a vertical position, so that the ingredients and oil are mixed and gathered on the food gathering part of the rotary pot. The motion control device executes control commands to control the bottom inductor to work, so as to adjust the output power of the bottom inductor to meet the heating temperature required for stir-frying and achieve the purpose of stir-frying.

[0143] Taking the cyclic stir-frying method as an example, the motion control device executes commands to control the power and working time of the control inductor to match the heating temperature and heating time during stir-frying. At the same time, the motion control device executes control commands to control the first drive device to drive the rotary pot to reciprocate and rotate, so that the ingredients are spread out or gathered, achieving the purpose of turning the ingredients. The motion control device executes control commands to control the second drive device to drive the rotary pot to reciprocate and rotate (self-rotate) to achieve the throwing and stirring of the ingredients. The motion control device issues control commands to control the third drive device to drive the scraper to reciprocate along the inner wall of the pot to achieve the stirring and mixing of the ingredients. After the above actions complete a specified cycle, the heating device, the first drive device and the third drive device stop working. The second drive device drives the rotary pot to rotate to the position with the opening facing downwards, so that the ingredients in the pot can be poured into a plate, achieving the purpose of serving the dish.

[0144] Example 15

[0145] Based on Embodiment Thirteen, the automatic cooking device further includes a scraper assembly disposed outside the rotary pot, the scraper assembly including a scraper and a third driving device; the method further includes:

[0146] In the stir-frying step, the third driving device drives the scraper to rotate around a set point outside the rotary pot, so that the part of the scraper in contact with the inner wall of the rotary pot moves back and forth between the opening and the bottom of the rotary pot to stir-fry the ingredients inside the rotary pot.

[0147] When cooking, the rotary cooker works in conjunction with the external scraper to allow the scraper to smoothly enter the cooker body and stir the ingredients. Therefore, the internal structure of the rotary cooker not only needs to meet the functions of spreading and gathering the ingredients for cooking, but also needs to meet the requirement that the scraper can enter the internal cavity from the opening of the rotary cooker and move back and forth between the opening and the bottom in contact with the internal cavity wall.

[0148] In this embodiment of the invention, the scraper is rotatably connected to a set point outside the rotary vessel via a connector. The scraper needs to be drivably swinging relative to this set point, so that the part of the scraper in contact with the inner wall inside the rotary vessel reciprocates between the opening and the bottom of the rotary vessel. Therefore, the internal structure of the rotary vessel determines whether the scraper can move smoothly within the internal cavity. The internal structure of the rotary vessel can be obtained from the above embodiments four to ten.

[0149] Example 16

[0150] Based on the above embodiment one, as Figure 21 This application also provides an automatic cooking control device 200 installed in an automatic cooking equipment. The automatic cooking control device 200 is connected to a motion control device and a heating device, and includes: a feeding control component 201, used to control the motion control device to drive the rotary pot to rotate so that the opening faces upward, so that the food is fed into the rotary pot through the opening; a heating control component 202, used to control the heating device to heat the food in the food gathering part or the food spreading part; and a turning control component 203, used to drive the motion control device to control the movement of the rotary pot so that the food in the rotary pot is in the food gathering part or the food spreading part.

[0151] The feeding control component 201 enables the rotary kettle to flip upwards, allowing for precise material input and preventing side feeding, ensuring accurate material placement. The heating control component 202 controls the food distribution area and the food spreading area to meet the heating needs of different ingredients, thus guaranteeing cooking quality. The turning control component 203 controls the rotary kettle's rotation, placing ingredients in either the food distribution area or the food spreading area during different cooking stages. The food distribution area gathers small ingredients and seasonings for thorough mixing and pre-cooking, improving the quality of these ingredients. When cooking the main ingredients, the rotary kettle can be turned horizontally, allowing larger quantities of main ingredients to spread out in the food spreading area for cooking, ensuring thorough heating or turning and guaranteeing overall cooking quality.

[0152] In this embodiment, the automatic cooking equipment further includes a second driving device for driving the rotary pot to rotate; by driving the rotary pot to rotate, the food is turned over inside the rotary pot, thereby improving the full heating of the food and ensuring the cooking quality of the food. Correspondingly, the automatic cooking control device also includes a tossing and stirring control component 204, used to control the second driving device to drive the rotary pot to reciprocate in a horizontal state to toss and stir the food. By controlling the reciprocating rotation of the rotary pot, the food is tossed, thereby making the food mix more evenly, the heating process more uniform, and further improving the cooking quality of the food.

[0153] In this embodiment, the automatic cooking equipment further includes a scraper assembly disposed outside the rotary pot, the scraper assembly including a scraper and a third driving device; correspondingly, the automatic cooking control device further includes a scraper stirring control assembly 205, used to control the third driving device to drive the scraper to rotate around a set point outside the rotary pot, so that the part of the scraper in contact with the inner wall of the rotary pot reciprocates between the opening and the bottom of the rotary pot, so as to stir-fry the food inside the rotary pot. Through the scraper and its driving device, when the food is stir-fried, the stirring by the scraper can further improve the mixing of the food and improve the heating uniformity of the food.

[0154] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
