[0002] In order to simplify the production process of the cooking machine cup body and the base for fixing the cup body, the sidewall of the cooking machine cup body is arranged to be perpendicular to the bottom surface of the cup body. When the cup body stirs the food materials, the up and down tumbling of the food materials in the cup body entirely relies on the action of the cutter, and the sidewall of the cup body only plays a role of limiting the food materials, so that the food materials are less reversed, which affects the cooking effect of the food materials.

[0003] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a cooking device to improve the working efficiency of the cooking device.

[0005] The technical scheme of the utility model is as follows:

[0006] A cooking device, comprising:

[0007] a cup body, an internal cavity is arranged therein; a vertical direction, an upper surface of the cup body is provided with a cup opening which is communicated with the cavity;

[0008] a cutter shaft, which extends into the cavity along the cup opening; a cutter is arranged on the cutter shaft;

[0009] wherein, a reflux section is arranged in the cavity; in the reflux section, the cavity cross section in the horizontal direction is designed to be tapered, and the cavity cross section in the horizontal direction is smaller as it is closer to the cup opening; the cutter is provided with a reflux section above.

[0010] A further technical scheme is that an upper part of the cup body is provided with a main machine; the main machine comprises a motor and a transmission assembly, and the transmission assembly is connected with the motor and the cutter shaft.

[0011] A further technical scheme is that a cavity wall of the cavity away from the cup opening is a bottom wall; a cavity wall of the cavity between the bottom wall and the cup opening is a sidewall; in the reflux section, the sidewall is inclined to the cutter shaft side in the direction close to the cup opening.

[0012] A further technical scheme is that the bottom wall is flat and horizontally arranged.

[0013] A further technical scheme is that the sidewall and the bottom wall are connected by a round corner.

[0014] Further, a transition section is arranged in the cavity, and the transition section is arranged between the backflow section and the bottom wall of the cavity.

[0015] Further, a transition section is arranged in the cavity, and the transition section is arranged between the backflow section and the bottom wall of the cavity.

[0016] Further, the radius of the circular arc-shaped side wall in the transition section is greater than the radius of the circular arc-shaped side wall in the backflow section.

[0017] Further, the cutter is a cutting knife set or a rolling pin.

[0018] Further, when the cutter is the cutting knife set, the cutting knife set comprises an upper knife set and a lower knife set, and the lower knife set is arranged at one end of the upper knife set close to the bottom of the cavity along the axis direction of the cutter shaft.

[0019] The utility model discloses the beneficial technical effects are as follows:

[0020] (1) the cooking device in the utility model, the cutter is arranged on the cutter shaft that stretches into the cup body, and food materials in the cup body are stirred and cut through the rotation of the cutter shaft. The cavity structure of the cavity is designed gradually tapered at the backflow section arranged in the cavity. When the cutter rotates and stirs the food materials in the cup body, the tapered side wall of the cup body will hinder the upward movement of the food materials and push the food materials towards the cutter shaft. When the cutter rotates and stirs the food materials, the food materials will be pushed away from the cutter shaft by the cutter, realizing the circular backflow of the food materials in the cup body, and further improving the tumbling efficiency of the food materials in the cup body. The tumbling efficiency of the food materials in the cup body is improved, the mixing uniformity of the food materials in the cup body is directly improved, and the food material processing efficiency of the cooking machine is further improved. In addition, the volume of the cavity can be expanded to accommodate more food materials under the premise that the cup opening is not expanded and the height of the cup body is not increased.

[0021] (2) Further, a fillet is arranged between the bottom wall and the side wall of the cup body, and the fillet reduces the dead angle in the cup body. The dead angle in the cup body is prone to accumulate food materials, causing uneven mixing of the food materials. The mixing uniformity of the food materials is directly improved by arranging the fillet to reduce the dead angle. When the cup body is cleaned subsequently

[0022] (3) Further, the backflow section is circular arc-shaped. That is, the side wall in the backflow section connecting the transition section has a smaller angle with the vertical direction, avoiding the side wall quickly approaching the blade shaft, compressing the rising space of the food material and hindering the movement process of the food material rising backflow. With the increase of the height, the closer to the cup opening, the larger the angle between the side wall in the backflow section and the vertical direction, that is, the faster the speed of the side wall in the backflow section approaching the blade shaft. The food material rising to this position has already left the working range of the knife, at this time, the side wall quickly approaches the blade shaft, which can more limit the upward movement of the food material, so that the food material backflows to re-enter the working range of the knife for stirring and chopping, and the processing efficiency of the food material is improved.

[0031] Figure 1 A vertical section structure schematic diagram of a cooking device of an embodiment of the present disclosure is shown. Please refer to Figure 1 , the cooking device includes a cup body 2 and a cutter shaft 3. The cup body 2 is internally provided with a cavity 22. In the vertical direction, the upper surface of the cup body 2 is provided with a cup opening 21 communicating with the cavity 22. The cutter shaft 3 extends into the cavity 22 along the cup opening 21. The cutter shaft 3 is provided with a cutter. The food materials in the cup body 2 are stirred and cut by the rotation of the cutter shaft 3. Among them, a reflux section 224 is arranged in the cavity 22. In the reflux section 224, the cavity section of the cavity 22 in the horizontal direction is designed to be tapered, and the cavity section of the cavity 22 in the horizontal direction becomes smaller as it gets closer to the cup opening 21. The cutter is provided above the reflux section 224. When the cutter rotates to stir the food materials in the cup body 2, the tapered side wall 221 of the cup body 2 will hinder the upward movement of the food materials and push the food materials towards the cutter shaft 3. When the cutter rotates to stir the food materials, the food materials will be pushed away from the cutter shaft 3 by the cutter, realizing the circular reflux of the food materials in the cup body 2, so that the food materials tumble in the cup body 2, thereby improving the tumbling efficiency of the food materials in the cup body 2. The improvement of the tumbling efficiency of the food materials in the cup body 2 directly improves the mixing uniformity of the food materials in the cup body 2, thereby improving the food material processing efficiency of the cooking machine. In addition, under the premise that the cup opening 21 is not enlarged and the height of the cup body 2 is not increased, the tapered reflux section 224 can enlarge the volume of the cavity 22 to accommodate more food materials.

[0032] Preferably, the cup body 2 can be a revolution body shape, that is, the cup body 2 is formed by rotating the bottom wall 223 and the side wall 221 as the revolution generatrix around the fixed axis, and the fixed axis is the central axis of the cup body 2. The symmetrical structure of the revolution body cup body 2 makes the cutter always close to the bottom wall 223 and the side wall 221 of the cup body 2, reducing the working blind area of the cutter in the cup body 2.

[0033] More preferably, the slope of the side wall 221 is too large, which also affects the upward movement of the food materials, resulting in weakened circulation of the food materials. That is, the angle between the side wall 221 and the vertical direction should be within a reasonable angle, that is, the angle between the side wall 221 and the vertical direction should not be greater than 30°, so as to avoid excessive reduction of the container cavity 22, which affects the upward movement of the food materials for rolling. It should be noted that in actual use, the angle between the side wall 221 and the vertical direction in the cooking device of the present application can also be greater than 30°, for example, the angle between the side wall 221 and the vertical direction can be 45° or greater than 45°, which does not limit the application range of the present application.

[0034] In the present embodiment, the upper part of the cup body 2 is provided with the main machine 1. The main machine 1 includes a motor 11 and a transmission assembly 12, and the transmission assembly 12 is connected to the motor 11 and the knife shaft 3. The transmission assembly 12 can be a gear transmission assembly 12, which transmits the torque output by the motor 11 to the knife shaft 3.

[0035] Please refer to Figure 1 , the cavity wall of the container cavity 22 away from the cup opening 21 is the bottom wall 223. The cavity wall of the container cavity 22 between the bottom wall 223 and the cup opening 21 is the side wall 221. In the backflow section 224, the side wall 221 inclines to the side of the knife shaft 3 in the direction close to the cup opening 21. The inclined side wall 221 reduces the horizontal cross section of the container cavity 22 to hinder the upward movement of the food materials pushed by the knife and push the food materials to the direction close to the knife shaft 3.

[0036] Preferably, the bottom wall 223 is flat and horizontally arranged to avoid generating dead corners, which are easy to accumulate food materials in the cup body 2, causing uneven mixing of the food materials and affecting the processing efficiency of the food materials. Reducing the generation of dead corners can improve the efficiency of the cooking device in processing food materials.

[0037] More preferably, the side wall 221 is connected to the bottom wall 223 through a round corner 222. The straight angle bottom is easy to accumulate food debris, and the round corner 222 structure reduces the groove through smooth transition to reduce the accumulation of food materials, so that the food materials in the cup body 2 are more easily mixed. At the same time, the smooth surface of the round corner 222 structure makes it easier for residues to be washed away by the water flow, thereby reducing the cleaning blind area of the cooking device.

[0038] Figure 2 A vertical cross-sectional structure diagram of the cup body and the knife shaft in the cooking device of an embodiment of the present disclosure is shown. Figure 3 A vertical cross-sectional structure diagram of the cup body and the knife shaft in the cooking device of an embodiment of the present disclosure is shown. Please refer to Figure 1 、 Figure 2 and Figure 3 , the knife is a cutting knife group or a dough kneading knife 41. Different types of knives are arranged on the knife shaft 3 to stir and cut different types of food materials. Multiple knife groups are arranged to improve the working range of the knives to more comprehensively cut and stir the food materials and improve the efficiency of the cooking device in processing food materials.

[0039] Preferably, the cutter is a cutting knife set. The cutting knife set includes an upper knife set 42 and a lower knife set 43. In the axial direction of the cutter shaft 3, the lower knife set 43 is arranged at one end of the upper knife set 42 close to the bottom of the container cavity 22. The blades in the lower knife set 43 are bent to form a bent portion 431 away from the end of the cutter shaft 3 to one side of the cup opening 21. The upper knife set 42 and the lower knife set 43 are arranged to form two groups of blades,

[0040] At the same time, the bent portion 431 on the lower knife set 43 can better stir the food materials in the cup body 2, improve the mixing efficiency of the food materials, and thus improve the efficiency of the cooking device in processing the food materials.

[0041] Figure 4 Fig. 1 shows a vertical cross-sectional view of a cooking device according to an embodiment of the present disclosure, showing the cup body and the cutter shaft. Please refer to Figure 1 and Figure 4 The container cavity 22 further comprises a transition section 225 arranged between the backflow section 224 and the bottom wall 223 of the container cavity 22. In the vertical direction, the inner side wall 221 of the transition section 225 is in the shape of a concave circular arc. The circular arc of the transition section 225 connects the backflow section 224 and the bottom wall 223, making the connection between the side wall 221 at the backflow section 224 and the bottom wall 223 smoother. The smooth cup body 2 reduces the frictional resistance between the food materials and the cup body 2, so that the food materials form a more uniform flow circulation and are mixed more uniformly during the processing, improving the processing efficiency of the food materials.

[0042] Preferably, in the vertical direction, the inner side wall 221 of the backflow section 224 is in the shape of a concave circular arc. The radius of the circular arc of the inner side wall 221 of the transition section 225 > the radius of the circular arc of the inner side wall 221 of the backflow section 224. The larger radius of the circular arc of the inner side wall 221 of the transition section 225 makes the inner side wall 221 of the transition section 225 smoother, avoiding the inner side wall 221 hindering the movement of the food materials in the vertical direction when the cutter stirs the food materials at the position of the transition section 225. At the same time, the backflow section 224 is in the shape of a circular arc, i.e., the angle between the side wall 221 connecting the transition section 225 and the vertical direction is small, avoiding the side wall 221 quickly approaching the cutter shaft 3 and compressing the upward space of the food materials to hinder the upward flow of the food materials. As the height increases, the closer to the cup opening 21, the larger the angle between the side wall 221 of the backflow section 224 and the vertical direction, i.e., the faster the speed of the side wall 221 of the backflow section 224 approaching the cutter shaft 3. The food materials that have risen to this position have already left the working range of the cutter, so that the side wall 221 quickly approaches the cutter shaft 3 can more effectively limit the upward movement of the food materials, so that the food materials re-enter the working range of the cutter for stirring and chopping, improving the processing efficiency of the food materials.

[0043] The specific working process of the present utility model is as follows:

[0044] When the food material is processed, the motor 11 drives the cutter shaft 3 to rotate, and drives the cutter to rotate and cut in the cup body 2, and stirs the food material. The food material stirred by the cutter moves away from the cutter shaft 3 under the action of centrifugal force. At the same time, part of the food material is stirred by the cutter and moves upward. Since the side wall 221 of the reflux section 224 is inclined, the side wall 221 is closer to the cutter shaft 3 closer to the cup opening 21. That is, the upwardly moving food material is limited by the side wall 221 to move upward, and is pushed by the side wall 221 to the cutter shaft 3. Finally, the upwardly moving food material falls into the working range of the cutter under the joint action of gravity and the side wall 221, and completes a round of annular reflux. The cutter shaft 3 is continuously driven to rotate, and the food material in the cup body 2 continuously performs annular reflux until the food material processing is completed.

[0045] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0046] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
