Description

Technical Field

[0001] This application relates to the technical field of small household appliances, and more particularly, to a cooking cup and a cooking machine. Background Art

[0002] In existing cooking machines, in order to achieve good cutting effects, high rotational speeds are required to drive the blades to cut food ingredients. However, high rotational speeds can lead to high noise generated by the motor, large collision and friction noise of the clutch, large friction noise of the bearing, large collision and friction noise of the blades cutting food ingredients, and large noise of the high-speed rotating food ingredients impacting the cup body, resulting in high noise of the entire machine and poor user experience. Summary of the Invention

[0003] This application provides a cooking cup and a cooking machine with low overall noise.

[0004] A cooking cup includes:

[0005] A cup body provided with a stirring cavity;

[0006] A stirring blade disposed in the stirring cavity, the stirring blade being rotatable relative to the cup body;

[0007] A fixed blade disposed in the stirring cavity, the fixed blade remaining relatively fixed to the cup body along the rotation direction of the stirring blade.

[0008] In this solution, the cutting efficiency is improved by adding the auxiliary cutting function of the fixed blade, so the rotational speed of the main machine can be appropriately reduced, the noise of the cooking machine can be reduced, and the user experience can be improved.

[0009] Optionally, the fixed blade includes a blade edge extending along the height direction of the cup body, the blade edge not facing the axis of the stirring blade, and being deflected in the opposite direction of the rotation direction of the stirring blade. With this setting, when the stirring blade rotates, the food ingredients are lifted and flow along the rotation direction of the stirring blade. The blade edge of the fixed blade faces the incoming direction of the food ingredients, which can better cut and break the food ingredients and further improve the cutting efficiency of the food ingredients.

[0010] Optionally, the deflection angle of the blade edge relative to the axis of the stirring blade is 20° - 60°. This deflection angle α is reasonably set and has good cutting effects.

[0011] Optionally, the cooking cup further includes a positioning component, the positioning component being in positioning cooperation with the cup body along the rotation direction of the stirring blade, and the fixed blade being fixedly connected to the positioning component. By cooperating and positioning the positioning component with the cup body, the fixed blade can be relatively fixed to the cup body in the direction around the axis of the stirring blade, and the positioning is more convenient and easier to achieve.

[0012] Optionally, the positioning component includes a first positioning portion and a second positioning portion. The fixed knife is fixedly connected to the first positioning portion and the second positioning portion. The first positioning portion is in positioning cooperation with the cup body in the rotation direction of the stirring knife, and the second positioning portion is in positioning cooperation with the cup body in the rotation direction. With such a setting, the fixed knife can achieve circumferential positioning with the cup body through at least two positioning portions, the positioning is more reliable, and it is also beneficial to the stability of the fixed knife during operation.

[0013] Optionally, the first positioning portion and the second positioning portion are spaced apart along the height direction of the cup body. The fixed knife extends along the height direction of the cup body. The upper end of the fixed knife is connected to the first positioning portion, and the lower end of the fixed knife is connected to the second positioning portion. This positioning method is adapted to the structure of the fixed knife, increasing the reliability of the fixed knife positioning and making the layout in the stirring cavity more reasonable.

[0014] Optionally, the first positioning portion, the second positioning portion, and the fixed knife are assembled to form a fixed knife module, and the fixed knife module is detachably connected to the cup body. With such a setting, it is convenient to clean and replace the fixed knife module, and it is also convenient to clean the stirring cavity and the stirring knife.

[0015] Optionally, in the height direction of the cup body, the second positioning portion is arranged higher than the stirring knife. This not only ensures the installation space of the fixed knife module in the stirring cavity but also enables the fixed knife and the stirring knife to synchronously cut the food materials.

[0016] Optionally, the first positioning portion is annular. The cooking cup further includes a mesh cover connected to the first positioning portion and disposed in the hollow portion of the first positioning portion. The mesh cover is provided with a plurality of defoaming holes. This mesh cover can eliminate the bubbles generated during whipping, improve the air blasting noise, and also block the space where the food materials diverge, which is beneficial to the food materials to flow back and reduce the risk of slurry overflow.

[0017] Optionally, the mesh cover includes a flat portion and a convex portion protruding from the flat portion. The convex portion protrudes towards the top of the cup body. Both the flat portion and the convex portion are provided with a plurality of defoaming holes. With such a setting, on the one hand, the space below the mesh cover can be increased, and on the other hand, the area of the mesh cover can be increased, so that more defoaming holes are formed on the flat portion and the convex portion of the mesh cover, and the defoaming ability is improved.

[0029] Here, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a certain specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0031] Please refer to Figure 1 , Figure 1 which is an exploded view of a cooking machine 100 shown in an exemplary embodiment of the present application.

[0032] The present application provides a cooking machine 100, which includes a main body 10 and a cooking cup 20. The cooking cup 20 is assembled above the main body 10. In one embodiment, the cooking cup 20 is detachably assembled above the main body 10.

[0033] The cooking cup 20 includes a cup body 21 and a cup lid 22 covering the cup body 21. The cup body 21 is provided with a stirring cavity 210 for whipping food ingredients, and the cup lid 22 can be covered on the cup body 21 by screwing. Specifically, one of the cup body 21 and the cup lid 22 is provided with a clamping portion 211, and the other is provided with a clamping and mating portion 220. When the cup lid 22 is screwed in place relative to the cup body 21, the clamping portion 211 and the clamping and mating portion 220 are correspondingly clamped. Of course, the way the cup lid 22 covers the cup body 21 is not limited to this.

[0034] Please refer to Figure 1 and Figure 2 , Figure 2 which is Figure 1 a cross-sectional view of the cup body 21 shown in

[0035] The cooking cup 20 further includes a stirring blade 23 and a fixed blade 24, both of which are arranged in the stirring cavity 210. Among them, the stirring blade 23 is rotatable relative to the cup body 21, and the fixed blade 24 remains relatively fixed to the cup body 21 in the rotation direction of the stirring blade 23. That is to say, the fixed blade 24 does not have a rotational degree of freedom and cannot rotate. And the fixed blade 24 is configured to be able to cut food ingredients together with the stirring blade 23.

[0036] According to the above description, during the whipping process, the fixed blade 24 can cooperate with the stirring blade 23 to cut food ingredients together. By doing so, the cutting efficiency is improved by adding the auxiliary cutting function of the fixed blade 24, so the rotation speed of the main body can be appropriately reduced, the noise of the cooking machine 100 can be reduced, and the user experience can be improved.

[0037] Please refer to Figure 1 and Figure 3 , Figure 3 which is Figure 2 a top view of the cup body 21 shown in

[0038] In one embodiment, the fixed blade 24 includes a blade edge 240 extending along the height direction of the cup body 21. The blade edge 240 is not directly opposite to the axis O of the stirring blade 23, but is deflected in the opposite direction of the rotation direction of the stirring blade 23. The "height direction" mentioned here can be a direction parallel to the axis of the stirring blade 23, or a direction inclined at a certain angle relative to the axis of the stirring blade 23.

[0039] With such a setting, when the stirring blade 23 rotates, the food ingredients are lifted and flow along the rotation direction of the stirring blade 23. The cutting edge 240 of the fixed blade 24 faces the incoming direction of the food ingredients, which can better cut and break the food ingredients and further improve the cutting efficiency of the food ingredients. Figure 3 The arrow in

[0040] In an alternative embodiment, the deflection angle α of the cutting edge 240 relative to the axis of the stirring blade 23 is 20° to 60°. This deflection angle α is reasonably set and has a good cutting effect. On the contrary, if the angle α is too small or too large, the cutting edge 240 cannot be fully utilized, resulting in a reduced contact probability between the food ingredients and the cutting edge 240. The deflection angle α can be selected between 20° and 60°, specifically it can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 60°, but not limited thereto.

[0041] Please refer to Figures 3 to 6 , Figure 4 which is Figure 3 a schematic diagram of the stirring blade 23 shown in Figure 5 is a top view of another embodiment of the cup body 21. Figure 6 It is Figure 5 a schematic diagram of the stirring blade 23 shown in

[0042] In Figure 3 and Figure 4 the embodiments shown, the stirring blade 23 adopts a large elevation angle blade type. In Figure 5 and Figure 6 the embodiments shown, the stirring blade 23 adopts a flat elevation and inclined wing blade type. The stirring blade 23 is provided with a cutting edge 230 on the forward rotation side, cuts the food ingredients while lifting them, and cooperates with the fixed blade 24 to shear the food ingredients bidirectionally, greatly improving the cutting efficiency and increasing the damping to improve the sound frequency and reduce the resonance noise. Based on the improvement of the cutting efficiency, the rotation speed of the main machine 10 can be appropriately reduced to reduce the overall machine noise.

[0043] The stirring blade 23 is rotatably arranged on the cutter disc 25, and the cutter disc 25 can be a heating disc. The cutter disc 25 is assembled at the bottom of the cup body 21 to form the bottom of the stirring cavity 210. The cutter shaft of the stirring blade 23 passes through the cutter disc 25 and is used to connect with the motor shaft in the main machine 10, and the stirring blade 23 rotates along with the rotation of the motor shaft.

[0044] In Figure 3 and Figure 5In the illustrated embodiment, the stirring blade 23 includes a plurality of blades, and the plurality of blades are distributed around the axis of the stirring blade 23. There are a plurality of fixed blades 24, and the plurality of fixed blades 24 are distributed around the axis of the stirring blade 23, and are farther from the axis of the stirring blade 23 than the blades of the stirring blade 23. The plurality of fixed blades 24 may be arranged at equal intervals, but are not limited thereto. The cutting edge 240 of each fixed blade 24 is not directly opposite to the axis of the stirring blade 23, and is deflected in the opposite direction to the rotation direction of the stirring blade 23.

[0045] This application does not specifically limit the installation method of the fixed blade 24 in the stirring cavity 210. For example, the fixed blade 24 can be fixedly installed on the cup body 21 and be fixedly maintained with the cup body 21 in all directions. Another example is that the fixed blade 24 can be fixed to the cup body 21 only in the direction around the axis of the stirring blade 23, and is not limited in other directions. In this embodiment, the latter is adopted.

[0046] Please refer to Figure 7 , Figure 7 which is a schematic diagram of the fixed blade module.

[0047] In one embodiment, the cooking cup 20 further includes a positioning assembly 26. The positioning assembly 26 is in positioning cooperation with the cup body 21 along the rotation direction of the stirring blade 23, and the fixed blade 24 is fixedly connected to the positioning assembly 26. In this way, by the positioning cooperation between the positioning assembly 26 and the cup body 21, the fixed blade 24 can be relatively fixed to the cup body 21 in the direction around the axis of the stirring blade 23, and the positioning is more convenient and easier to achieve.

[0048] In one embodiment, the positioning assembly 26 includes a first positioning portion 261 and a second positioning portion 262. The fixed blade 24 is connected between the first positioning portion 261 and the second positioning portion 262. The first positioning portion 261 is in positioning cooperation with the cup body 21 along the rotation direction of the stirring blade 23, and the second positioning portion 262 is in positioning cooperation with the cup body 21 along the rotation direction of the stirring blade 23. With such a setting, the fixed blade 24 can achieve circumferential positioning with the cup body 21 through at least two positioning portions, the positioning is more reliable, and it is also beneficial to the stability of the fixed blade 24 during operation. The manner in which the fixed blade 24 is connected to the first positioning portion 261 and the second positioning portion 262 includes but is not limited to welding or riveting.

[0049] In Figure 7In the illustrated embodiment, the first positioning portion 261 and the second positioning portion 262 are spaced apart in the height direction of the cup body 21. The first positioning portion 261 is located above the second positioning portion 262. The fixed knife 24 extends in the height direction of the cup body 21. Among them, the upper end of the fixed knife 24 is connected to the first positioning portion 261, and the lower end of the fixed knife 24 is connected to the second positioning portion 262. That is to say, the first positioning portion 261 can be used to position the fixed knife 24 at the top with the cup body 21, and the second positioning portion 262 can be used to position the fixed knife 24 at the bottom with the cup body 21. This positioning method is adapted to the structure of the fixed knife 24, increasing the reliability of the positioning of the fixed knife 24 and making the layout in the stirring cavity 210 more reasonable.

[0050] It should also be noted that since the fixed knife 24 extends in the height direction of the cup body 21, it can also take into account different amounts of ingredients in the stirring cavity 210. For example, if there is less ingredient in the stirring cavity 210, the lower part of the fixed knife 24 can be used to beat the ingredients. If there is more ingredient in the stirring cavity 210, the entire fixed knife 24 can be used to beat the ingredients, and the requirement for the amount of ingredients in the stirring cavity 210 is relatively low.

[0051] The specific structure of the first positioning portion 261 cooperating with the cup body 21 for positioning is not limited. In Figure 7 the illustrated embodiment, the first positioning portion 261 can be arranged in an annular structure, but is not limited thereto. The outer surface of the first positioning portion 261 is provided with a first positioning groove 2610. Correspondingly, a first positioning boss (not shown) can be provided on the inner surface of the cup body 21, and the first positioning boss is in positioning cooperation with the first positioning groove 2610. Of course, a first positioning boss can also be provided on the outer surface of the first positioning portion 261, and a first positioning groove can be provided on the inner surface of the cup body 21. A plurality of first positioning grooves 2610 and first positioning bosses can be provided, and they are arranged in one-to-one correspondence.

[0052] The specific structure of the second positioning portion 262 cooperating with the cup body 21 for positioning is not limited. In Figure 7 the illustrated embodiment, the second positioning portion 262 can be arranged in an annular structure, but is not limited thereto. The outer surface of the second positioning portion 262 is provided with a second positioning groove 2620. Correspondingly, a second positioning boss (not shown) can be provided on the inner surface of the cup body 21, and the second positioning boss is in positioning cooperation with the second positioning groove 2620. Of course, a second positioning boss can also be provided on the outer surface of the second positioning portion 262, and a second positioning groove can be provided on the inner surface of the cup body 21. A plurality of second positioning grooves 2620 and second positioning bosses can be provided, and they are arranged in one-to-one correspondence.

[0053] In Figure 7In the illustrated embodiment, a plurality of fixed knives 24 are provided. The upper ends of the respective fixed knives 24 are all connected to the first positioning portion 261, and the lower ends of the respective fixed knives 24 are all connected to the second positioning portion 262.

[0054] In one embodiment, the first positioning portion 261, the second positioning portion 262, and the fixed knife 24 are assembled to form a fixed knife module, and the fixed knife module is detachably connected to the cup body 21. With such a setting, it is convenient to clean and replace the fixed knife module, and it is also convenient to clean the stirring cavity 210 and the stirring knife 23.

[0055] In Figure 7 In the illustrated embodiment, the detachable connection structure between the fixed knife module and the cup body 21 can be realized through the positioning structures of the two. For example, the first positioning groove 2610 and the first positioning boss are arranged to extend along the height direction of the cup body, and the second positioning groove 2620 and the second positioning boss are arranged to extend along the height direction of the cup body. The fixed knife module is arranged to be inserted into the stirring cavity 210 along the height direction of the cup body 21. After being inserted in place, the first positioning boss is located in the first positioning groove 2610, and the second positioning boss is located in the second positioning groove 2620. In this way, the above positioning structure can not only achieve positioning but also achieve detachability.

[0056] In Figure 7 In the illustrated embodiment, both the first positioning portion 261 and the second positioning portion 262 are arranged in an annular structure. For the convenience of assembly, the diameter of the first positioning portion 261 is set to be smaller than the diameter of the second positioning portion 262. Of course, in some other embodiments, according to the shape of the stirring cavity 210 and under the condition that the internal space permits, the first positioning portion 261 and the second positioning portion 262 can be arranged in a structure with equal diameters.

[0057] In one embodiment, the fixed knife module is arranged above the stirring knife 23. That is to say, in the height direction of the cup body 21, the second positioning portion 262 is arranged higher than the stirring knife 23. When the stirring knife 23 rotates, the food ingredients are lifted and come into contact with the cutting edge 240 of the fixed knife 24, which not only ensures the installation space of the fixed knife module in the stirring cavity 210 but also can play the role of synchronously cutting the food ingredients by the fixed knife 24 and the stirring knife 23.

[0058] In Figure 7 In the illustrated embodiment, a cover body 27 can be provided in the hollow portion of the first positioning portion 261. The cover body 27 is connected to the first positioning portion 261 and is arranged directly above the stirring knife 23. The cover body 27 can be arranged as a cover body with a non-porous structure to prevent the food ingredients from overflowing.

[0059] Please refer to Figure 8 , Figure 8 which is a schematic diagram of another embodiment of the fixed knife module.

[0060] In one embodiment, the first positioning portion 261 is arranged in an annular structure and extends around the axis of the stirring blade 23. The cooking cup 20 further includes a screen cover 28 connected to the first positioning portion 261 and disposed in the hollow of the first positioning portion 261. The screen cover 28 is provided with a plurality of defoaming holes 2800. The screen cover 28 can eliminate the bubbles generated during whipping, improve the air-burst noise, and can also block the space where the food materials diverge, which is beneficial to the backflow of the food materials and reduces the risk of slurry overflow. It should be noted that the defoaming holes 2800 on the screen cover 28 can be formed by micro-hole processing.

[0061] In one embodiment, the screen cover 28 includes a flat portion 280 and a convex portion 281 protruding from the flat portion 280. The convex portion 281 protrudes towards the top of the cup body 21. A plurality of defoaming holes are provided on both the flat portion 280 and the convex portion 281. With such an arrangement, on the one hand, the space below the screen cover 28 can be increased, and on the other hand, the area of the screen cover 28 can be increased, so that more defoaming holes 2800 are formed on the flat portion 280 and the convex portion 281 of the screen cover 28, and the defoaming ability is improved. In Figure 8 In the illustrated embodiment, the convex portion 281 has a frustum of a cone structure with a larger bottom diameter and a smaller top diameter, but it is not limited thereto.

[0062] In Figure 8 In the illustrated embodiment, in order to further fix the deformation resistance ability of the fixed knife 24, a convex bump 241 can also be provided on the fixed knife 24, and the convex bump 241 extends along the length direction of the fixed knife 24.
