Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a stirring structure and a cooking appliance. Background Technology

[0002] The stir-fry machine is a technological product developed to meet users' cooking needs. Users simply put the prepared ingredients into the machine's container, and it automatically cooks the food, which is very convenient. For users who are skilled in cooking, the stir-fry machine not only saves labor costs but also avoids the pollution caused by cooking fumes. For users who are not skilled in cooking, the stir-fry machine allows even those who cannot cook to make delicious dishes.

[0003] However, the mixing structure of the stir-fry machine has corners. During the mixing process, the ingredients can easily get stuck at the corners, resulting in poor mixing effect. Utility Model Content

[0004] The main purpose of this invention is to provide a stirring structure and cooking appliance to solve the problem of poor stirring effect in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a stirring structure is provided, comprising: a first connecting ear plate; a second connecting ear plate, spaced apart from and coaxially arranged with respect to the first connecting ear plate; and a stirring blade connected between the first and second connecting ear plates, the stirring blade comprising a first twisted section, a middle section, and a second twisted section connected in sequence, wherein the end of the first twisted section away from the middle section is connected to the first connecting ear plate, and the end of the second twisted section away from the middle section is connected to the second connecting ear plate; wherein the first twisted section is twisted from the middle section toward the first connecting ear plate, and the second twisted section is twisted from the middle section toward the second connecting ear plate, and the connection between the first twisted section and the middle section, as well as the connection between the middle section and the second twisted section, are smoothly transitioned.

[0006] By applying the technical solution of this utility model, during the rotation of the stirring blade driven by the first or second connecting ear plate, the first twisted section is twisted from the middle section towards the first connecting ear plate, and the second twisted section is twisted from the middle section towards the second connecting ear plate. Furthermore, the connections between the first twisted section and the middle section, as well as between the middle section and the second twisted section, are smoothly transitioned. This eliminates the presence of corners at these connections, reducing the possibility of food getting stuck. This facilitates uniform mixing of the food and improves the mixing effect. Therefore, the technical solution of this application effectively solves the problem of poor mixing effect in related technologies.

[0007] Furthermore, the side of the first connecting ear plate that is opposite to the second connecting ear plate is designated as the first side, and the side of the second connecting ear plate that is opposite to the first connecting ear plate is designated as the second side. The surface of the first twisted section that is opposite to the second twisted section is designated as the first surface, which is perpendicular to the rotation axis of the first connecting ear plate. Similarly, the surface of the second twisted section that is opposite to the first twisted section is designated as the second surface, which is also perpendicular to the rotation axis of the first connecting ear plate. This structure helps reduce the resistance of the stirring structure during the stirring process, while ensuring a stable connection between the stirring blades and the first and second connecting ear plates, thereby improving the overall strength of the stirring structure.

[0008] Furthermore, the first surface and the first side are smoothly connected, and the second surface and the second side are smoothly connected. This smooth transition facilitates continuous agitation of the ingredients, reduces resistance during mixing, and makes the mixing process smoother. Moreover, the smooth transition design increases the contact area between the mixing blades and the first and second connecting lugs, improving connection strength, reducing vibration of the mixing blades during high-speed rotation, and enhancing the overall stability and durability of the mixing structure.

[0009] Furthermore, a vertical plane passing through the rotation axis of the first connecting ear plate is set as a reference plane, and the side of the middle section is parallel to the reference plane, or the side of the middle section intersects the reference plane. This arrangement allows the stirring blades to effectively cover the bottom area of ​​the appliance body when stirring food, enabling the stirring of more food and improving stirring efficiency.

[0010] Furthermore, along the rotation axis of the first connecting ear plate, the tilt angle of one of the first and second twisted segments relative to the reference surface gradually decreases, while the tilt angle of the other of the first and second twisted segments relative to the reference surface gradually increases. These gradually changing tilt angles of the first and second twisted segments optimize the stirring path of the stirring blades within the pot, allowing the stirring blades to more effectively cover the entire bottom of the vessel body, thus improving stirring efficiency. Moreover, the different tilt angles help disperse the food, preventing excessive concentration of food in a certain area at the bottom of the vessel body, ensuring even heating and stirring of the food.

[0011] Furthermore, in order to facilitate a smooth transition at the connection between the first twisted segment and the middle segment, as well as at the connection between the middle segment and the second twisted segment, the inner edge of the middle segment is an inner arc surface or an inner plane, and the outer edge of the middle segment is an outer arc surface or an outer plane, wherein the outer edge is located outside the inner edge.

[0012] Furthermore, in the inner and outer directions of the first twisted section, the cross-sectional area at any position of the first twisted section is equal, and the cross-sectional area of ​​the first twisted section is equal to that of the second twisted section. This equality of cross-sectional area helps the stirring blades generate a balanced force during rotation, preventing over-stirring or uneven stirring in certain areas, thereby ensuring uniform heating and cooking of the food.

[0013] According to another aspect of the present invention, a cooking utensil is provided, including an utensil body and a stirring structure rotatably disposed on the utensil body, wherein the stirring structure is the stirring structure described above.

[0014] Furthermore, the appliance body includes a pot body with a rim. The side of the first connecting lug plate that is opposite to the second connecting lug plate is designated as the first side, and the side of the second connecting lug plate that is opposite to the first connecting lug plate is designated as the second side. Both the first and second sides are parallel to the inner surface of the rim. This arrangement helps reduce the resistance of the stirring structure during the stirring process, while ensuring a stable connection between the stirring blades and the first and second connecting lug plates, thus improving the overall strength of the stirring structure.

[0015] Furthermore, the stirring blade has a stirring surface, and in the direction from the first connecting lug and / or the second connecting lug to the middle section of the stirring blade, the angle between the stirring surface and the inner surface of the pot gradually changes from 0 degrees to 90 degrees. During the stirring process, the aforementioned stirring blade can gradually push from the bottom of the pot towards the side, improving the ability of the stirring surface to cover the bottom and sides of the pot, ensuring comprehensive stirring and uniform processing of the ingredients. Moreover, the changing angle between the stirring blade and the pot helps reduce food jamming at corners, preventing food accumulation and improving the stirring effect of the stirring structure.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] like Figures 1 to 5 As shown, this application provides a stirring structure, an embodiment of which includes: a first connecting lug 10, a second connecting lug 20, and a stirring blade 30. The second connecting lug 20 is spaced apart from and coaxially arranged with the first connecting lug 10. The stirring blade 30 is connected between the first connecting lug 10 and the second connecting lug 20, and the stirring blade 30 includes a first twisted section 31, a middle section 32, and a second twisted section 33 connected in sequence. The end of the first twisted section 31 away from the middle section 32 is connected to the first connecting lug 10, and the end of the second twisted section 33 away from the middle section 32 is connected to the second connecting lug 20. The first twisted section 31 is twisted from the middle section 32 toward the first connecting lug 10, and the second twisted section 33 is twisted from the middle section 32 toward the second connecting lug 20, with smooth transitions at the connections between the first twisted section 31 and the middle section 32, and between the middle section 32 and the second twisted section 33.

[0035] By applying the technical solution of this embodiment, during the rotation of the stirring blade 30 driven by the first connecting ear plate 10 or the second connecting ear plate 20, the first twisted segment 31 is twisted from the middle segment 32 toward the first connecting ear plate 10, and the second twisted segment 33 is twisted from the middle segment 32 toward the second connecting ear plate 20, with smooth transitions at the connections between the first twisted segment 31 and the middle segment 32, and between the middle segment 32 and the second twisted segment 33. This eliminates the presence of corners at the connections between the first twisted segment 31 and the middle segment 32, and between the middle segment 32 and the second twisted segment 33, reducing the possibility of food 43 getting stuck at these points. This facilitates uniform stirring of the food 43 and improves the stirring effect. Therefore, the technical solution of this embodiment effectively solves the problem of poor stirring effect in related technologies.

[0036] It should be noted that the smooth transition at the connection between the first twisted segment 31 and the middle segment 32, as well as the connection between the middle segment 32 and the second twisted segment 33, means that there is an angle greater than 150 degrees between the first twisted segment 31 and the middle segment 32, and between the middle segment 32 and the second twisted segment 33.

[0037] like Figures 1 to 8 As shown, in this embodiment, the connection between the first twisted segment 31 and the middle segment 32, as well as the connection between the middle segment 32 and the second twisted segment 33, are all smoothly transitioned. This ensures that there are no corners at the connection between the first twisted segment 31 and the middle segment 32, and the connection between the middle segment 32 and the second twisted segment 33, thus avoiding stress concentration at these points and improving the structural strength of the stirring blade 30.

[0038] The first twisted segment 31 is twisted from the middle segment 32 toward the first connecting ear plate 10, and the second twisted segment 33 is twisted from the middle segment 32 toward the second connecting ear plate 20. When the stirring structure is at its lowest position, from a top-down view of the stirring structure, the first twisted segment 31 has a first inclined segment forming a first angle with the rotation axis L1 of the first connecting ear plate, and the second twisted segment 33 has a second inclined segment forming a second angle with the rotation axis L1 of the first connecting ear plate. The range of the first and second angles is 10° to 50°. This inclined first and second inclined segments are beneficial for greasing the pan when hot oil is applied (increasing the greasing area) and can also increase the uniformity of stirring. At the same time, during one counterclockwise rotation of the stirring blade 30, the first twisted segment 31 and the second twisted segment 33 simultaneously compress the food 43; during one clockwise rotation of the stirring blade 30, the first twisted segment 31 and the second twisted segment 33 simultaneously flip the food 43. Alternatively, in other embodiments, during one revolution of the stirring blade 30, a portion of the twisting of the first twisting section 31 and the second twisting section 33 simultaneously compresses the food 43, while the other portion of the twisting of the first twisting section 31 and the second twisting section 33 simultaneously flips the food 43.

[0039] like Figures 1 to 5 As shown, the side of the first connecting ear plate 10 that is opposite to the second connecting ear plate 20 is called the first side 11, and the side of the second connecting ear plate 20 that is opposite to the first connecting ear plate 10 is called the second side 21. The surface of the first twisted segment 31 that is opposite to the second twisted segment 33 is called the first surface 311, which is perpendicular to the rotation axis L1 of the first connecting ear plate. The surface of the second twisted segment 33 that is opposite to the first twisted segment 31 is called the second surface 331, which is perpendicular to the rotation axis L1 of the first connecting ear plate. The above structure helps to reduce the resistance of the stirring structure during the stirring process, while ensuring that the stirring blades are firmly connected to the first connecting ear plate 10 and the second connecting ear plate 20, thereby improving the overall strength of the stirring structure.

[0040] like Figures 1 to 5 As shown, the first surface 311 is smoothly connected to the first side 11, and the second surface 331 is smoothly connected to the second side 21. This smooth transition facilitates continuous agitation of the ingredients, reduces resistance during mixing, and makes the mixing process of the stirring blade 30 smoother. Furthermore, the smooth transition design increases the contact area between the stirring blade 30 and the first connecting ear plate 10 and the second connecting ear plate 20, improving connection strength, reducing vibration of the stirring blade 30 during high-speed rotation, and enhancing the overall stability and durability of the mixing structure.

[0041] like Figures 1 to 5As shown, the vertical plane passing through the rotation axis L1 of the first connecting ear plate is set as the reference plane A1, and the side of the middle section 32 intersects the reference plane A1. This arrangement allows the stirring blade 30 to effectively cover the bottom area of ​​the appliance body when stirring the ingredients 43, enabling the stirring of more ingredients and improving stirring efficiency.

[0042] In other embodiments, the side of the intermediate segment is parallel to the reference plane.

[0043] like Figures 1 to 5 As shown, along the rotation axis L1 of the first connecting ear plate, the tilt angle of the first twisted segment 31 relative to the reference surface A1 gradually decreases, while the tilt angle of the second twisted segment 33 relative to the reference surface A1 gradually increases. These gradually changing tilt angles of the first and second twisted segments optimize the stirring path of the stirring blades within the pot, allowing the stirring blades 30 to more effectively cover the entire bottom of the vessel body, thus improving stirring efficiency. Furthermore, the different tilt angles help disperse the ingredients, preventing excessive concentration in a certain area at the bottom of the vessel body, ensuring even heating and stirring. Additionally, different tilt angles reduce dead zones during stirring, resulting in more comprehensive stirring and improved cooking outcomes.

[0044] Of course, in other embodiments, along the rotation axis L1 of the first connecting ear plate, the tilt angle of the second twisted segment 33 relative to the reference surface A1 gradually decreases, while the tilt angle of the first twisted segment 31 relative to the reference surface A1 gradually increases.

[0045] like Figures 1 to 5 As shown, in order to facilitate a smooth transition at the connection between the first twisted segment 31 and the middle segment 32, as well as at the connection between the middle segment 32 and the second twisted segment 33, the inner edge 321 of the middle segment 32 is an inner plane, and the outer edge 322 of the middle segment 32 is an outer plane, wherein the outer edge 322 is located outside the inner edge 321.

[0046] In other embodiments, the inner edge 321 of the middle segment 32 is an inner arc surface, and the outer edge 322 of the middle segment 32 is an outer arc surface.

[0047] like Figures 1 to 5 As shown, the cross-sectional area of ​​the first twisted segment 31 is equal at any position in the inner and outer directions, and the cross-sectional area of ​​the first twisted segment 31 is equal to that of the second twisted segment 33. This equal cross-sectional area helps the stirring blade 30 generate a balanced force during rotation, preventing over-stirring or uneven stirring in certain areas, thereby ensuring uniform heating and cooking of the food.

[0048] This application also provides a cooking utensil, such as Figures 5 to 8As shown, an embodiment of the cooking appliance includes an appliance body and a stirring structure rotatably mounted on the appliance body. The stirring structure is the stirring structure described above. Since the aforementioned stirring structure can solve the problem of poor stirring effect in related technologies, the cooking appliance including this stirring structure can solve the same technical problem.

[0049] like Figures 2 to 6 As shown, the appliance body includes a pot body 40 with a pot opening 41. The side of the first connecting lug 10 opposite to the second connecting lug 20 is designated as the first side 11, and the side of the second connecting lug 20 opposite to the first connecting lug 10 is designated as the second side 21. Both the first side 11 and the second side 21 are parallel to the inner surface 411 of the pot opening 41. This arrangement helps reduce the resistance of the stirring structure during the stirring process, while ensuring a stable connection between the stirring blade 30 and the first connecting lug 10 and the second connecting lug 20, thus improving the overall strength of the stirring structure.

[0050] like Figures 2 to 8 As shown, the stirring blade 30 has a stirring surface. In the direction from the first connecting lug 10 and / or the second connecting lug 20 to the middle section 32 of the stirring blade 30, the angle between the stirring surface and the inner surface of the pot body 40 gradually changes from 0 degrees to 90 degrees. During stirring, the stirring blade 30 can gradually push from the bottom of the pot body 40 to the side of the pot body 40, improving the ability of the stirring surface to cover the bottom and sides of the pot body 40, ensuring comprehensive stirring and uniform processing of the ingredients. Furthermore, as the angle between the stirring surface and the inner surface of the pot body 40 increases, the stirring blade 30 can better turn the ingredients from the bottom of the pot body 40 to the side of the pot body 40, and then push them back from the side of the pot body 40 to the bottom, forming a cyclical turning of the ingredients, improving the mixing efficiency and cooking quality. Moreover, the changing angle between the stirring blade 30 and the pot body 40 helps reduce food jamming at corners, avoiding food accumulation and improving the stirring effect of the stirring structure.

[0051] like Figures 2 to 8 As shown, the bottom of the utensil body includes a spherical or flat portion 42. Different bottom shapes can adapt to different cooking needs. The spherical bottom helps to coat the pan when hot oil is applied, while the flat bottom provides more stable heating. Both can improve the efficiency of the stirring mechanism and the cooking effect.

[0052] In this embodiment, the cooking appliance further includes a support 54 and a drive motor mounted on the support 54. The drive motor and the first connecting ear plate 10 are connected by a coupling 52, which passes through the pot body 40. A sealing sleeve 51 is provided at the coupling 52. A magnet 53 is provided on the coupling 52 for detecting the rotational position of the coupling 52. A fixing pin 55 is provided on the pot body 40 at a position opposite to the coupling 52, and the second connecting ear plate 20 is sleeved on the fixing pin 55. The drive motor drives the first connecting ear plate 10 to rotate through the coupling 52.

[0053] In other embodiments, the aforementioned appliance body includes a cup body.

[0054] In one embodiment, the cooking appliance is a stir-fry machine; in other embodiments, the cooking appliance is a dough mixer, a whipping machine, a soy milk maker, a blender, or a multi-functional pot.

[0055] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
