Description

TECHNICAL FIELD

[0001] The utility model relates to small household electrical appliances technical field, specifically, relates to a stirring structure and cooking utensil. BACKGROUND

[0002] The cooking utensil is one of indispensable tools in the kitchen, and its stirring function can help us cook delicious food more easily. Whether it is stirring batter, whipping egg white or stirring seasoning, the cooking utensil can quickly and evenly complete the task, saving the trouble of manual stirring. In addition, the cooking utensil also has multiple functions, such as stirring, egg beating, dough kneading, etc., which can meet the production needs of different dishes.

[0003] However, the cooking utensil has a stirring structure for realizing the stirring function. In the process of stirring food materials, the stirring structure is easy to scrape all the food materials in the cooking utensil, leading to the empty burning in the cooking utensil. Moreover, in the process of stirring food materials, the stirring structure can only turn over the whole layer of food materials, resulting in uneven stirring. SUMMARY

[0004] The main purpose of the utility model is to provide a stirring structure and cooking utensil to solve the problems of empty burning in the cooking utensil and uneven stirring of the stirring structure in the related technology.

[0005] In order to achieve the above purpose, according to one aspect of the utility model, a stirring structure is provided, which comprises: a first connecting shaft; a second connecting shaft, which is coaxially arranged with the first connecting shaft; and a stirring blade, which is connected between the first connecting shaft and the second connecting shaft, and comprises a first stirring section, an intermediate section and a second stirring section connected in sequence, wherein the width of the intermediate section is smaller than that of the first stirring section.

[0006] By applying the technical scheme of the utility model, the first connecting shaft or the second connecting shaft drives the stirring blade to rotate, so that the stirring blade can stir food materials. During the rotation of the stirring blade, the area of the intermediate section in contact with the food materials is smaller than that of the first stirring section. In this way, the intermediate section can scrape the food materials on the bottom layer, and the food materials above the food materials on the bottom layer will naturally fall to the position of the food materials on the bottom layer just scraped, timely filling, avoiding the empty burning in the cooking utensil. At the same time, the first stirring section can scrape the food materials on another layer. During the long-time stirring process, the positions of the food materials on the bottom layer and the food materials above the food materials on the bottom layer and the food materials on another layer are constantly exchanged, avoiding the turning over of the whole layer of food materials, which is conducive to improving the uniformity of stirring. Therefore, the technical scheme of the present application effectively solves the problems of empty burning in the cooking utensil and uneven stirring of the stirring structure in the related technology.

[0007] Further, the width of the middle section is less than the width of the second stirring section. This design allows the stirring blade to better separate the food materials when stirring, with the middle section being able to more flexibly stir the bottom layer of food materials, and the second stirring section being able to more forcefully stir the other layers of food materials. During the long stirring process, the positions of the bottom layer of food materials and the upper layers of food materials are constantly exchanged, increasing the stirring level and improving the uniformity of the mixed food materials.

[0008] Further, when the stirring structure is in the lowest position, the lowest part of the first stirring section and the lowest part of the second stirring section are both protruding from the lowest part of the middle section. This allows the upper layers of food materials to quickly fill the gap left by the bottom layer of food materials even if the middle section has scraped up the bottom layer of food materials, reducing the risk of empty burning caused by the entire scraping of the food materials. The protruding first stirring section and second stirring section also help the circulation of food materials in the cooking appliance, promoting the mixing of food materials between different layers and improving the uniformity and efficiency of stirring.

[0009] Further, to facilitate temperature measurement, the bottom of the pot is a small plane, and the lowest part of the middle section is a plane. This allows the plane of the lowest part of the middle section to be adaptively arranged with the small plane.

[0010] Further, in the direction from the inner side of the stirring blade to the outer side of the stirring blade, the middle section includes an equal-thickness section and a variable-thickness section connected to the equal-thickness section. The arrangement of the equal-thickness section and the variable-thickness section can optimize the strength and rigidity of the stirring blade and improve the ability of the stirring blade to resist deformation.

[0011] Further, in the direction from the inner side of the stirring blade to the outer side of the stirring blade, the thickness of the variable-thickness section gradually decreases. The change in the thickness of the variable-thickness section allows the stirring blade to be more flexible when stirring food materials, especially when stirring thick food materials, reducing the stirring resistance and avoiding uneven stirring caused by the excessive thickness of the stirring blade.

[0012] Further, the connection between the middle section and the first stirring section is smoothly transitioned; and / or, the connection between the middle section and the second stirring section is smoothly transitioned. The smooth transition of the connection between the middle section and the first stirring section and the second stirring section can reduce the resistance during the stirring process of the stirring blade, making the stirring action more smooth.

[0013] Further, when the stirring structure is located at the lowest position, the middle section has a lowest area, a straight line perpendicular to the rotation axis of the first connecting shaft and passing through the midpoint of the lowest area is set as a reference line, and the middle section is arranged in a twisted manner relative to the reference line. The above-mentioned twisted arrangement can increase the contact area of the stirring blades with the food materials, further improve the uniformity and efficiency of stirring, and meanwhile, the twisted arrangement is also helpful to the turning of the food materials and avoids local accumulation of the food materials.

[0014] Further, the first stirring section comprises a first inclined section arranged in an inclined manner relative to the rotation axis of the first connecting shaft, the second stirring section comprises a second inclined section arranged in an inclined manner relative to the rotation axis of the first connecting shaft, and the middle section is connected between the first inclined section and the second inclined section; and / or, the stirring structure further comprises a stirring rib connected to the first stirring section and the second stirring section, and a through hole is formed between the stirring rib, the first stirring section, the middle section and the second stirring section. The stirring rib can strengthen the structural strength of the stirring blades and improve the turning performance of the stirring blades, and the through hole formed can increase the flowability of the food materials, so that part of the food materials can pass through the through hole, reduce the stirring resistance of the stirring blades, and make the stirring blades more flexible when turning the food materials, thereby facilitating the improvement of the stirring uniformity.

[0015] According to another aspect of the present application, a cooking appliance is provided, which comprises an appliance body and a stirring structure rotatably arranged on the appliance body, wherein the stirring structure is the above-mentioned stirring structure.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not intended to limit the present application and its application or use in any way. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0030] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and furthermore, it should be understood that when the terms "comprise" and / or "include" are used in the specification, there is a presence of a feature, step, operation, device, component and / or combinations thereof.

[0031] The relative arrangement of parts and steps, numerical expressions, and numerical values set forth in the Examples are not intended to limit the scope of the present application unless specifically stated otherwise. At the same time, it should be understood that the dimensions of the various parts shown in the drawings are not drawn to actual scale for ease of illustration. Techniques, methods, and equipment known to those of ordinary skill in the relevant art can not be discussed in detail because such techniques, methods, and equipment are considered to be part of the state of the art. In all examples shown and discussed herein, any specific value is to be interpreted as merely exemplary and not as a limitation. Thus, other examples of exemplary embodiments can have different values. It should be noted that like reference numerals and letters refer to like items throughout the several views, and once an item is defined in one view, it need not be discussed further in subsequent views.

[0032] As Figures 1 to 5 shown, the present application provides a stirring structure, and an embodiment of the stirring structure includes a first connecting shaft 10, a second connecting shaft 20, and a stirring blade 30. The second connecting shaft 20 is coaxially arranged with the first connecting shaft 10. The stirring blade 30 is connected between the first connecting shaft 10 and the second connecting shaft 20, and the stirring blade 30 includes a first stirring section 31, an intermediate section 32, and a second stirring section 33 connected in sequence. The width W1 of the intermediate section is less than the width W2 of the first stirring section.

[0033] By applying the technical solution of the embodiment, the first connecting shaft 10 drives the stirring blade 30 to rotate, so that the stirring blade 30 can stir the food material 41. During the rotation of the stirring blade 30, because the width W1 of the intermediate section is less than the width W2 of the first stirring section, the area of the intermediate section 32 in contact with the food material 41 is less than the area of the first stirring section 31 in contact with the food material 41. In this way, the intermediate section 32 can scrape off the food material on the bottom layer, and the food material above the food material on the bottom layer will naturally fall to the position of the food material on the bottom layer that has just been scraped off after the food material on the bottom layer is scraped off, timely filling, avoiding empty burning in the cooking appliance; at the same time, the first stirring section 31 can scrape off another layer of food material. During the long stirring process, the positions of the food material on the bottom layer and the food material above the food material on the bottom layer and the food material on another layer are constantly exchanged, avoiding the food material on the whole layer being able to be flipped only, which is conducive to improving the uniformity of stirring. Therefore, the technical solution of the embodiment effectively solves the problems of easy empty burning in the cooking appliance and non-uniform stirring of the stirring structure in the related art.

[0034] The stirring structure of the embodiment is rotatably installed in an appliance body 40 of a cooking appliance.

[0035] As Figures 1 to 5As shown, the width W1 of the middle section is smaller than the width W3 of the second mixing section. This design allows the mixing blade 30 to better process the ingredients in layers during mixing. The middle section 32 can more flexibly turn over the bottom layer of ingredients, while the second mixing section 33 can more powerfully mix the other layers of ingredients. During the long mixing process, the positions of the bottom layer of ingredients, the top layer of ingredients, and the other layers of ingredients are constantly interchanged, increasing the sense of layering in the mixing and improving the uniformity of the ingredients.

[0036] It should be noted that the “width” in the width of the middle section, the width of the first stirring section and the width of the second stirring section in this application refers to the dimension in the direction from the inner side of the stirring blade 30 to the outer side of the stirring blade 30.

[0037] like Figures 1 to 5 As shown, when the stirring structure is in its lowest position, the lowest point of the first stirring section 31 and the lowest point of the second stirring section 33 both protrude beyond the lowest point of the middle section 32. Thus, the stirring blades 30 move along... Figure 5 During the stirring process, even if the middle section 32 scrapes up the bottom layer of ingredients, the ingredients above will quickly fill the gaps left by the scraped ingredients due to the presence of the first stirring section 31 and the second stirring section 33, reducing the risk of dry burning caused by all the ingredients being scraped away. At the same time, the protruding first stirring section 31 and the second stirring section 33 help the ingredients circulate within the cooking appliance, promoting mixing between different layers and preventing excessive concentration of ingredients in one layer, thus improving the uniformity and efficiency of stirring.

[0038] like Figures 1 to 5 As shown, for convenient temperature measurement, the bottom of the pot body is a small flat surface, and the lowest point of the middle section 32 is a flat surface 321. In this way, the flat surface at the lowest point of the middle section is adapted to the small flat surface.

[0039] like Figures 3 to 5 As shown, in the direction from the inner side to the outer side of the stirring blade 30, the intermediate section 32 includes a constant thickness section 322 and a variable thickness section 323 connected to the constant thickness section 322. The arrangement of the constant thickness section 322 and the variable thickness section 323 in the direction from the inner side to the outer side of the stirring blade 30 can optimize the strength and rigidity of the stirring blade 30 and improve the stirring blade 30's ability to resist deformation.

[0040] The thickness of the intermediate section 32 mentioned above refers to the dimension of the intermediate section 32 in the direction of rotation of the stirring blade 30.

[0041] like Figures 3 to 5As shown, the thickness W4 of the thickened section gradually decreases from the inner side of the stirring blade 30 to the outer side of the stirring blade 30. The thickness change of the thickened section 323 can make the stirring blade 30 more flexible when turning over the food materials, especially when stirring thick food materials, can reduce the stirring resistance, and avoid uneven stirring caused by the over-thickness of the stirring blade 30.

[0042] In other embodiments, the thickness W4 of the thickened section gradually increases from the inner side of the stirring blade 30 to the outer side of the stirring blade 30.

[0043] Further, the connection between the intermediate section 32 and the first stirring section 31 is smoothly transitioned; the connection between the intermediate section 32 and the second stirring section 33 is smoothly transitioned. The smooth transition at the connection between the intermediate section 32 and the first stirring section 31 and the second stirring section 33 can reduce the resistance in the stirring process of the stirring blade 30, make the stirring action more fluent, and also help the food to be evenly distributed in the stirring process, avoiding the accumulation of food materials at the edge of the stirring blade.

[0044] The above-mentioned "smooth transition" refers to the smooth, natural and seamless transition process at the connection between the intermediate section 32 and the first stirring section 31 and the second stirring section 33, which will not be abrupt or unnatural.

[0045] Further, when the stirring structure is located at the lowest position, the intermediate section 32 has a lowest area, a straight line passing through the midpoint of the lowest area and perpendicular to the rotation axis L1 of the first connecting shaft is set as a reference line L2, and the intermediate section 32 is twisted relative to the reference line L2. The above-mentioned twisted arrangement can increase the area of the stirring blade 30 in contact with the food materials 41, further improve the uniformity and efficiency of stirring, and the twisted arrangement also helps to turn over the food materials and avoid local accumulation of the food materials. It should be noted that the above-mentioned lowest area refers to a point area or a line area or a surface area.

[0046] Further, the first stirring section 31 includes a first inclined section 311 which is inclinedly arranged relative to the rotation axis L1 of the first connecting shaft, the second stirring section 33 includes a second inclined section 331 which is inclinedly arranged relative to the rotation axis L1 of the first connecting shaft, and the intermediate section 32 is connected between the first inclined section 311 and the second inclined section 331. The inclined design of the first inclined section 311 and the second inclined section 331 can make the stirring blade 30 better adapt to the distribution of the food materials when rotating, improve the turning efficiency, and also help the food materials to be evenly distributed in the appliance body 40.

[0047] The stirring structure further comprises a stirring rib 34 connected to the first stirring section 31 and the second stirring section 33, and a through hole 35 is formed between the stirring rib 34, the first stirring section 31, the intermediate section 32 and the second stirring section 33. The stirring rib 34 can strengthen the structural strength of the stirring blade 30, and the through hole 35 can increase the flowability of the food materials, so that part of the food materials can pass through the through hole 35, reduce the stirring resistance of the stirring blade 30, and make the stirring blade 30 more flexible when stirring the food materials, thereby improving the stirring uniformity.

[0048] In the embodiment, when the stirring structure is located at the lowest position, the intermediate section 32 has a lowest area, a straight line perpendicular to the rotation axis L1 of the first connecting shaft and passing through the midpoint of the lowest area is set as a reference line L2, and the intermediate section 32 is centrally symmetrically arranged relative to the reference line L2. The lowest area is a point area, a line area or a surface area.

[0049] The application further provides a cooking appliance, and an embodiment of the cooking appliance comprises an appliance body 40 and a stirring structure rotatably arranged on the appliance body 40, wherein the stirring structure is the stirring structure described above. The stirring structure described above can solve the problems of easy empty burning and uneven stirring of the stirring structure in the related art, so that the cooking appliance comprising the stirring structure can solve the same technical problems.

[0050] The cooking appliance further comprises a driving motor for driving the first connecting shaft 10 to rotate. Specifically, the first connecting shaft 10 is provided with a first connecting hole connected with a motor shaft of the driving motor, and the second connecting shaft 20 is provided with a second connecting hole connected with a connecting shaft of the appliance body. The first connecting shaft 10 and the second connecting shaft 20 are coaxially arranged, so that the first connecting shaft 10 can drive the stirring blade 30 to rotate more stably.

[0051] The appliance body 40 described above comprises a cup body or a pot body. The embodiment of the cooking appliance is a stir-fry machine, and in other embodiments, the cooking appliance is a dough maker, a whipping machine, a soybean milk machine, a breaking wall machine or a multifunctional pot.

[0052] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" and the like indicate the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and in the absence of the opposite description, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present application; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0053] For purposes of the description hereinafter, spatial relative terms, such as "above", "below", "upper", "lower", and the like, can be used to describe the relative position of one element or feature to another as illustrated in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures.

Thus, the exemplary term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatial relative descriptors used herein interpreted accordingly.

[0054] In addition, it should be noted that the use of "first", "second", and the like words of distinction do not connote any meaning of importance, but are used solely to differentiate one element from another, and are used in the context of this application without implying any specific order, or order of precedence. Accordingly, a first element that follows an operation can be performed before, after, or at the same time as a second element that precedes the operation.

[0055] The preferred embodiments of the present application have been described above with the purpose of enabling not only the best modes of practicing the application known to the inventors at this time, but also of enabling others skilled in the art to utilize the application in various embodiments and with various modifications as are suited to the particular use contemplated.
