[0003] Specifically, such a cooking appliance generally sets stirring blades in a cooking cavity and drives the stirring blades to rotate by a motor to realize the stirring of food to simulate the stirring of food by a person. However, the cooking appliance in the related art can only slightly stir food, and cannot realize a three-dimensional stir-frying function, especially for long strip-shaped (for example, leafy vegetables) and granular food, the stirring is not uniform enough, which causes a large difference in taste of food in the same pot and affects the user experience. SUMMARY
[0004] The main purpose of the present application is to provide a stirring device and a cooking appliance with the same to solve the problem of uneven stirring in the related art which causes a large difference in taste of food.
[0005] In order to achieve the above-mentioned purpose, according to the first aspect of the present application, a stirring device is provided, comprising: a first stirring member having a first rotation axis, the first stirring member comprising a downward hook portion, an end portion of the downward hook portion extending towards the first rotation axis; a second stirring member located on the inner side of the downward hook portion, the second stirring member having a second rotation axis, the second stirring member extending towards a direction away from the second rotation axis, wherein the second rotation axis is parallel to or coincides with the first rotation axis, and the second stirring member and the first stirring member can relatively rotate.
[0006] By applying the technical scheme of the present application, the stirring device comprises a first stirring member and a second stirring member, wherein the second stirring member extends towards a direction away from the second rotation axis, which can stir food located inside the accommodating cavity of the cooking appliance; the end portion of the downward hook portion of the first stirring member extends towards the first rotation axis, which can stir food located outside the accommodating cavity of the cooking appliance. The first stirring member and the second stirring member can relatively rotate, that is, the first stirring member and the second stirring member can intersect or be staggered, and the first stirring member or the second stirring member can change the state of the food when the first stirring member and the second stirring member intersect, so that the food is turned over in the accommodating cavity, and then the food can be uniformly stirred to ensure the consistency of the taste of food in the same pot. Therefore, the technical scheme of the present application can effectively solve the problem of uneven stirring in the related art which causes a large difference in taste of food.
[0007] Further, the rotation direction of the first stirring member is opposite to the rotation direction of the second stirring member. The first stirring member and the second stirring member respectively apply opposite direction forces to the food, so that the food can be fully stirred, thereby ensuring the taste of the food.
[0008] Further, the rotation direction of the first stirring member is the same as the rotation direction of the second stirring member, and the rotation speed of the first stirring member is different from the rotation speed of the second stirring member. The first stirring member and the second stirring member rotate in the same direction at different speeds, and there is a speed difference between the two, so that the food can be turned over in the cooking cavity, thereby ensuring the cooking effect.
[0009] Further, the distance between the end of the first stirring member and the end of the second stirring member in the radial direction of the coverage range of the first stirring member is between 0 and 10 mm. The distance in the above range can avoid interference between the ends of the first stirring member and the second stirring member when they intersect, or food being stuck between the ends of the two, while ensuring that the food in the accommodation cavity can be stirred. At the same time, the above distance enables the ends of the first stirring member and the second stirring member to extrude the food between the two ends, which can scatter small particles of food, thereby ensuring good stirring effect for various food.
[0010] Further, the stirring device further comprises a rotating shaft portion, and the first stirring member further comprises a connecting arm connected between the rotating shaft portion and the downward hook portion. The downward hook portion is connected to the rotating shaft portion through the connecting arm and is driven to rotate by the rotating shaft portion, having the advantage of simple structure.
[0011] Further, the downward hook portion comprises a turning section and a stirring section, the turning section is located between the connecting arm and the stirring section, and the stirring section comprises a bottom surface and first and second side surfaces disposed on both sides of the bottom surface. The first side surface is inclined with respect to the bottom surface and forms an acute angle with the bottom surface, and the first side surface is a first food contact surface. The first side surface is inclined with respect to the bottom surface, so that the food can rise a distance along the first side surface and then fall back into the accommodation cavity, thereby realizing the turning of the food.
[0012] Further, the first stirring member can rotate forward and reverse, the second side surface is a second food contact surface, the upper edge of the second side surface is connected to the upper edge of the first side surface, and the angle between the second side surface and the bottom surface is greater than the angle between the first side surface and the bottom surface. The two sides of the bottom surface are respectively provided with the first and second food contact surfaces, so that the first stirring member will contact and push or turn the food regardless of forward or reverse rotation. Specifically, the first side surface can realize the turning of the food, and the second side surface can push the food forward, and the two food contact surfaces can meet the cooking needs of different food.
[0013] Further, the cross-sectional height of the stirring section is in a range from 5 mm to 15 mm. The cross-sectional height of the stirring section in the above range can ensure the stirring effect.
[0014] Further, the connecting arm is gradually inclined upward from inside to outside, and the included angle between the connecting arm and the horizontal direction is between 10° and 60°, and / or the cross section of the connecting arm is a trapezoidal structure with the upper small and the lower large. The connecting arm is arranged in such a shape that after the user adds food materials or seasonings during cooking, the food materials or seasonings can slide into the accommodation cavity along the upper surface of the connecting arm and the two side walls of the trapezoidal structure, without hanging or staying on the connecting arm.
[0015] Further, the end of the downwardly extending hook portion is provided with a thinning portion, and the cross-sectional height of the thinning portion gradually decreases in the direction close to the first rotation axis. In this way, food can be effectively prevented from being stuck between the end of the downwardly extending hook portion and the end of the second stirring piece.
[0016] According to a second aspect of the present application, a cooking appliance is provided, comprising a container and a stirring device, the container having an accommodation cavity, and the stirring device being arranged in the accommodation cavity, and the stirring device being the above-mentioned stirring device. The above-mentioned stirring device can effectively solve the problem of uneven stirring in the related art, which causes the food to have large differences in taste.

[0017] Further, the ratio between the distance between the end of the second stirring piece and the longitudinal center line of the accommodation cavity and the size of the downwardly extending hook portion along the radial direction of the container is between 2 / 3 and 7 / 3. The ratio in the above range ensures that the second stirring piece and the downwardly extending hook portion both have sufficient stirring length to achieve their respective stirring functions.
[0018] Further, the ratio between the distance between the end of the second stirring piece and the longitudinal center line of the accommodation cavity and the radius of the mouth portion of the container is between 0.4 and 0.7. When the ratio is between 0.4 and 0.7, the stirring effect can be ensured even when there is less food, and the downwardly extending hook portion and the second stirring piece can both have better contact with the food, improving the stirring effect.
[0019] Further, the container comprises a side wall extending in the vertical direction and a bottom wall, and the bottom wall comprises an arc-shaped section, and the ratio between the size of the arc-shaped section along the radial direction of the container and the radius of the side wall is between 0.55 and 0.7.

[0058] Figures 1 to 9 A structure schematic diagram of an embodiment one of a cooking utensil according to the present application is shown. The cooking utensil includes a stirring device.
[0059] As Figure 1 , Figure 2 , Figure 5 , Figure 8 and Figure 9As shown, the stirring device of the cooking utensil of the first embodiment of the present application comprises a first stirring piece 20 and a second stirring piece 30. The first stirring piece 20 has a first rotation axis, and comprises a downward hook portion 21, the end of which extends towards the first rotation axis. The second stirring piece 30 is located at the inner side of the downward hook portion 21, and has a second rotation axis, and extends towards a direction away from the second rotation axis, wherein the second rotation axis is parallel to or coincides with the first rotation axis, and the second stirring piece 30 and the first stirring piece 20 can rotate relative to each other.
[0060] By applying the technical solution of the present embodiment, the stirring device comprises the first stirring piece 20 and the second stirring piece 30, wherein the second stirring piece 30 extends towards a direction away from the second rotation axis, and can stir the food located inside the accommodating cavity 11 of the cooking utensil; the end of the downward hook portion 21 of the first stirring piece 20 extends towards the first rotation axis, and can stir the food located outside the accommodating cavity 11 of the cooking utensil. The first stirring piece 20 and the second stirring piece 30 can rotate relative to each other, i.e. the first stirring piece 20 and the second stirring piece 30 can intersect or be staggered, and the first stirring piece 20 or the second stirring piece 30 can change the state of the food when the first stirring piece 20 and the second stirring piece 30 intersect, so as to make the food (especially the food located at the end of the downward hook portion 21 and the end of the second stirring piece 30) turn over in the accommodating cavity 11, and thus uniformly stir the food, and ensure the consistency of the taste of the food in the same pot. Therefore, the technical solution of the present embodiment can effectively solve the problem of uneven stirring in the related art, which causes large differences in the taste of the food.
[0061] It should be noted that the downward hook portion 21 has a free end and a connecting end connected to other components of the first stirring piece 20, and the "end of the downward hook portion 21" above refers to the free end of the downward hook portion 21. Correspondingly, the second stirring piece 30 also has a connecting end and a free end, and the "the second stirring piece 30 extends towards a direction away from the second rotation axis" above refers to that the free end of the second stirring piece 30 is away from the second rotation axis relative to the connecting end. The "inside and outside of the accommodating cavity 11" above are located in the space formed by the cavity wall of the accommodating cavity 11, wherein the "inside" refers to the position close to the center of the accommodating cavity 11, and the "outside" refers to the position away from the center of the accommodating cavity 11.
[0062] Specifically, in the present embodiment, the rotation direction of the first stirring piece 20 is opposite to the rotation direction of the second stirring piece 30. The first stirring piece 20 and the second stirring piece 30 respectively exert forces in opposite directions on the food, so that the food can be fully stirred, and thus the taste of the food is ensured.
[0063] AsFigure 2 and Figure 4 As shown in FIG. 1, the distance L1 between the end of the first stirring member 20 and the end of the second stirring member 30 in the radial direction of the coverage of the first stirring member 20 is between 0 and 10 mm (the distance here refers to the distance in the radial direction of the coverage of the first stirring member 20 when the two meet).
[0064] For the distance L1 between the end of the first stirring member 20 and the end of the second stirring member 30 in the radial direction of the coverage of the first stirring member 20, the inventors conducted cooking experiments, and the specific experimental records are as follows:
[0065]
[0066] From the above experimental records, it can be seen that the distance L1 in the above range can avoid interference between the ends of the first stirring member 20 and the second stirring member 30 or food being stuck between the ends of the two members to form a jam, and at the same time, the stirring range of the first stirring member 20 and the second stirring member 30 can cover most of the area of the bottom wall of the containing cavity 11, ensuring that the food in the containing cavity 11 can be stirred. At the same time, the above distance L1 enables the ends of the first stirring member 20 and the second stirring member 30 to extrude the food between the two ends, which can disperse small-particle food (such as shredded meat, eggs, etc.), ensuring good stirring effect on various foods. Preferably, the distance L1 can be 5 mm, 7 mm, or 10 mm.
[0067] When the first stirring member 20 and the second stirring member 30 are both made of rubber, the above distance L1 can be set to 0, at which time the end of the first stirring member 20 and the end of the second stirring member 30 meet in a transition fit.
[0068] As shown in FIG. 1, the distance L1 between the end of the first stirring member 20 and the end of the second stirring member 30 in the radial direction of the coverage of the first stirring member 20 is between 0 and 10 mm (the distance here refers to the distance in the radial direction of the coverage of the first stirring member 20 when the two meet). Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 and Figure 9 As shown in FIG. 1, the distance L1 between the end of the first stirring member 20 and the end of the second stirring member 30 in the radial direction of the coverage of the first stirring member 20 is between 0 and 10 mm (the distance here refers to the distance in the radial direction of the coverage of the first stirring member 20 when the two meet).
[0069] Specifically, in the present embodiment, the first stirring member 20 and the second stirring member 30 can be driven to rotate in opposite directions by one motor cooperating with a gear set. Of course, in an embodiment not shown in the drawings, the first stirring member and the second stirring member can also be driven to rotate by two motors respectively.
[0070] As shown in Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 9 illustrated, the downwardly extending hook portion 21 includes a turning section 211 and a stirring section 212, the turning section 211 is located between the connecting arm 22 and the stirring section 212, the stirring section 212 includes a bottom surface 2121 and a first side surface 2122 and a second side surface 2123 disposed on both sides of the bottom surface 2121, the first side surface 2122 is disposed obliquely relative to the bottom surface 2121 and forms an acute angle with the bottom surface 2121, and the first side surface 2122 is a first food contact surface. The first side surface 2122 is disposed obliquely relative to the bottom surface 2121, so that the food can rise along the first side surface 2122 for a distance and then fall back into the accommodating cavity 11, thereby achieving the turning of the food.
[0071] As shown in Figures 6 to 9 , the first stirring member 20 can rotate forward and reverse, the second side surface 2123 is a second food contact surface, the upper edge of the second side surface 2123 is connected with the upper edge of the first side surface 2122, and the included angle A1 between the second side surface 2123 and the bottom surface 2121 is greater than the included angle A2 between the first side surface 2122 and the bottom surface 2121. The first food contact surface and the second food contact surface are disposed on both sides of the bottom surface 2121, so that the first stirring member 20 will contact and push or turn the food regardless of forward rotation or reverse rotation. Specifically, the included angle A2 between the first side surface 2122 and the bottom surface 2121 is small, the food can move upward along the first side surface 2122 for a distance and then roll down from the front side of the first side surface 2122 or roll down from the rear side of the first side surface 2122 to achieve the turning of the food; the included angle A1 between the second side surface 2123 and the bottom surface 2121 is large, and the food can be pushed forward. In a specific cooking process, the food can be pushed by the first side surface 2122, the food can be pushed by the second side surface 2123, or the food can be pushed alternately by the first side surface 2122 and the second side surface 2123 according to the characteristics of the food (such as particle size, particle shape), etc., so as to meet the cooking needs of different foods.
[0072] As shown in Figures 6 to 9 , the cross-sectional height H1 of the stirring section 212 is in the range of 5mm to 15mm. The cross-sectional height H1 in the above range enables the food to climb over the stirring section 212 and then roll over after climbing over the stirring section 212, so as to ensure the turning effect. Preferably, the cross-sectional height H1 can be 5mm, 10mm or 15mm.
[0073] As shown in Figure 2 and Figure 5 , the connecting arm 22 is gradually inclined upward from inside to outside, and the included angle A5 between the connecting arm 22 and the horizontal direction is between 10° and 60°. During cooking, after the user adds food materials or seasonings, the food materials or seasonings can slide along the upper surface of the connecting arm 22 into the containing cavity 11, and will not hang or stay on the connecting arm 22. Preferably, the above-mentioned included angle A5 can be 10°, 35° or 60°.
[0074] As shown in Figure 2 and Figure 5 , the cross section of the connecting arm 22 is a trapezoidal structure with the upper small and the lower large. During cooking, after the user adds food materials or seasonings, the food materials or seasonings can slide along the two side walls of the trapezoidal structure into the containing cavity 11, and will not hang or stay on the connecting arm 22. Specifically, the height of the trapezoidal structure is less than or equal to 5mm, and the inclination angle between the two side walls and the bottom wall of the trapezoidal structure is less than or equal to 70°.
[0075] In the embodiment, the end of the downwardly extending hook portion 21 is provided with a thinning portion, and the height of the cross section of the thinning portion gradually decreases in the direction close to the first rotation axis. That is, in the direction close to the second stirring piece 30, the size in the height direction of the thinning portion gradually decreases, which can effectively avoid food being stuck between the end of the downwardly extending hook portion 21 and the end of the second stirring piece 30.
[0076] The application also provides a cooking appliance, Figures 1 to 9 The structural schematic diagram of the embodiment one of the cooking appliance according to the application is shown.
[0077] Specifically, the cooking appliance of the embodiment includes a container 10 and a stirring device, the container 10 has a containing cavity 11, and the stirring device is arranged in the containing cavity 11, and the stirring device is the above-mentioned stirring device. The above-mentioned stirring device can effectively solve the problem of uneven stirring in the related art, which causes the food to have large taste difference, and the cooking appliance with the above-mentioned stirring device also has the above-mentioned advantages.
[0078] Specifically, when the stirring device is located in the containing cavity 11, the end of the downwardly extending hook portion 21 extends towards the middle part of the containing cavity 11, and the free end of the second stirring piece 30 extends in the direction away from the middle part of the containing cavity 11.
[0079] As shown in Figure 2As shown, in the present embodiment, the container 10 comprises a side wall 12 extending along a vertical direction and a bottom wall 13 comprising an arc-shaped section 131, a ratio between a radial direction size L9 of the arc-shaped section 131 and a radius R2 of the side wall 12 is between 0.55 and 0.7. That is, the radial direction size L9 of the arc-shaped section 131 is relatively large, when the food is less, the food located at the arc-shaped section 131 is easy to roll to a middle position of the container 10 along the arc-shaped section 131, that is, has a gathering effect on the food. Preferably, L9 / R2 can be 0.55, 0.6, 0.65 or 0.7.
[0080] As shown, Figure 6 a ratio between a distance L2 between an end of the second stirring piece 30 and a longitudinal center line of the containing cavity 11 and a radial direction size L3 of the downwardly extending hook section 21 is between 2 / 3 and 7 / 3. When the ratio between L2 and L3 is within the above range, it is ensured that the second stirring piece 30 and the downwardly extending hook section 21 both have sufficient stirring length to achieve respective stirring functions. A better dispersing and stir-frying effect can be achieved for the scenario of less food (for example, less than 100g of shredded meat or one egg).
[0081] As shown, Figure 2 and Figure 6 a ratio between the distance L2 between the end of the second stirring piece 30 and the longitudinal center line of the containing cavity 11 and a radius R1 of the mouth of the container 10 is between 0.4 and 0.7.
[0082] For the ratio between the distance L2 between the end of the second stirring piece 30 and the longitudinal center line of the containing cavity 11 and the radius R1 of the mouth of the container 10, the inventors have conducted cooking experiments, and the specific experimental records are as follows:
[0083]
[0084] Specifically, the above-mentioned "disturbance effect" refers to the pushing of food forward by the second stirring piece 30, and the above-mentioned "dispersing" refers to the dispersing of a block structure formed by a plurality of small-particle food materials into a plurality of small-particle food materials or the dispersing of an egg or other food materials that can solidify after being heated from a liquid state at room temperature into a plurality of small-particle solid structures.
[0085] As can be seen from the above experimental records, when L2 / R1 is within the above range, a better dispersing and stir-frying effect can be achieved for the scenario of less food (for example, less than 100g of shredded meat or one egg). At the same time, it is ensured that the downwardly extending hook section 21 has sufficient stirring length to achieve the corresponding stirring function. Preferably, the above-mentioned ratio can be 0.4, 0.55 or 0.7.
[0086] Specifically, in the present embodiment, the distance between the connecting position of the connecting arm 22 and the bottom wall of the container 10 is between 60mm and 100mm, which can ensure the stability of the rotation of the rotation shaft 40 during the driving of the first stirring piece 20, and avoid large swing due to the distance being too high, while also maximizing the height of the tumbling space to increase the amount of food that can be cooked.
[0087] As shown in Figures 6 to 9 , the inclination angle A3 of the first side surface 2122 relative to the inner wall of the container 10 is in the range of 20° to 45°. The inclination angle A3 in the above range allows the food to move upwards along the first side surface 2122 and be flipped, avoiding the food from being unable to be flipped due to insufficient rising height or being unable to rise along the first side surface 2122 and thus being pushed forward, ensuring the flipping effect on the food. Preferably, the inclination angle A3 can be 20°, 30°, 40° or 45°.
[0088] As shown in Figures 6 to 9 , the inclination angle A4 of the bottom surface 2121 relative to the inner wall of the container 10 is in the range of 3° to 10°. The inclination angle A4 in the above range allows the stirring section 212 to form effective line contact with the inner wall of the container 10, ensuring the flipping effect on the food while also minimizing the friction between the stirring section 212 and the inner wall of the container.
[0089] As shown in Figure 5 , the turning section 211 is provided outwardly convex on one side corresponding to the first side surface 2122, the ratio between the distance L5 between the intersection of the turning section 211 and the stirring section 212 and the bottom wall of the container 10 and the depth L6 of the container 10 is between 0.4 and 0.6, and the ratio between the maximum size L7 of the turning section 211 convex on the first side surface 2122 and the maximum transverse size L8 of the turning section 211 is between 0.6 and 0.8. During cooking, the part of the food moving upwards along the first side surface 2122 moves to the inner wall of the convex part of the turning section 211, and under the action of the inner wall of the convex part, the food moves forward and falls into the bottom of the container 10, achieving the flipping function on the food. Specifically, considering the common recipes and the amount of food for a meal in the process of home cooking, the ratio between the distance L5 between the intersection of the turning section 211 and the stirring section 212 and the bottom wall of the container 10 and the depth L6 of the container 10 is between 0.4 and 0.6, and the top surface of the food is near the intersection of the turning section 211 and the stirring section 212, so that the lower extension hook part 21 can have a better flipping effect on the food. Preferably, L5 / L6 can be 0.4, 0.45, 0.5 or 0.6, and L7 / L8 can be 0.6, 0.7, 0.75 or 0.8.
[0090] Specifically, as shown in Figure 2 andFigure 3 As shown in the figure, in the embodiment, the material of the first stirring member 20 is metal or plastic, and the gap L4 between the stirring section 212 and the inner wall of the container 10 is between 0.5 mm and 2 mm. When the gap L4 is within the above range, the interference between the stirring section 212 and the inner wall of the container 10 can be avoided, the normal rotation of the first stirring member 20 is not affected, and at the same time, it can be ensured that the food close to or adhered to the inner wall of the container 10 can be stirred, and the cooking effect is ensured. Preferably, the gap L4 can be 0.5 mm, 1 mm, 1.5 mm or 2 mm.
[0091] Of course, the first stirring member 20 includes a support body and a flexible covering member wrapped around the outer periphery of the support body, and the gap L4 between the stirring section 212 and the inner wall of the container 10 is between -0.5 mm and 1.5 mm. Since the flexible covering member has a certain deformation ability, it can be slightly interference-fitted with the inner wall of the container 10. When the gap L4 is within the above range, the friction between the stirring section 212 and the inner wall of the container 10 is small, the normal rotation of the first stirring member 20 is ensured, and at the same time, it can be ensured that the food close to or adhered to the inner wall of the container 10 can be stirred, and the cooking effect is ensured. Preferably, the above-mentioned flexible covering member can be rubber, and the gap L4 can be -0.5 mm, 0 mm, 0.5 mm, 1 mm or 1.5 mm.
[0092] In the embodiment, the distance between the highest point of the first stirring member 20 and the mouth of the container 10 is between -15 mm and 15 mm, so that when the user lifts the container 10 to pour the food, the user can press the top position of the first stirring member 20 with his hand to prevent it from falling off.
[0093] Figure 10 And Figure 11 The figure shows a structure schematic diagram of the first stirring member of the second embodiment of the cooking appliance according to the present application.
[0094] Among them, the difference between the cooking appliance of the second embodiment and the cooking appliance of the first embodiment is only that the structure of the first stirring member is different. Specifically, as shown in the figure, Figure 10 And Figure 11 As shown in the figure, the first side surface 2122 and the second side surface 2123 of the first stirring member 20 are symmetrically arranged relative to the center surface of the first stirring member 20, wherein the first side surface 2122 and the second side surface 2123 can make the food roll down after moving a distance thereon, and whether the first stirring member 20 rotates forward or reversely, it can play a role in stirring the food, so that the cooking effect is better.
[0095] As shown in the figure, Figure 10 And Figure 11As shown, the end of the downward hook portion 21 is provided with a thinning portion 213, the height of the cross section of the thinning portion 213 gradually decreases along the direction from the outside to the inside of the container 10. That is, in the direction close to the second stirring member 30, the size of the thinning portion 213 in the height direction gradually decreases, so that food can be effectively prevented from being stuck between the end of the downward hook portion 21 and the end of the second stirring member 30.
[0096] The present application also provides another cooking utensil (Embodiment Three), which is different from the cooking utensils of Embodiment One and Embodiment Two in that the stirring directions of the stirring members are different. In Embodiment Three, the rotating direction of the first stirring member 20 is the same as that of the second stirring member 30, and the rotating speed of the first stirring member 20 is different from that of the second stirring member 30. The first stirring member 20 and the second stirring member 30 rotate at the same direction but at different speeds, and there is a speed difference between them, so that food can be turned over in the cooking cavity, thereby ensuring the cooking effect.
[0097] In the present embodiment, the cooking utensil is a multifunctional cooking utensil with a stir-frying function. Of course, in the embodiments not shown in the drawings, the cooking utensil can also be a rice cooker, a pressure cooker, a low-pressure rice cooker, a soybean milk machine, a food processor, a stir-frying machine, an electric stewing pot, a multifunctional pot, etc.
