Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a stirring structure and a kitchen waste processor. Background Art

[0002] In modern society, kitchen waste processors have increasingly become essential equipment for households and the catering industry. They can efficiently process various kitchen wastes, reduce environmental pollution, and can also be converted into renewable resources such as fertilizers or biofuels. However, traditional kitchen waste processors usually adopt a single stirring structure, such as a linear stirring rod or a simple disc-shaped stirring blade. Although these stirring structures can perform basic stirring and crushing functions, their efficiency and effect are often unsatisfactory when dealing with large pieces of kitchen waste or mixing different types of kitchen waste.

[0003] Firstly, due to their relatively simple design, traditional stirring structures often cannot provide sufficient stirring area and strength. Especially when dealing with large pieces of kitchen waste, such as melon rinds, bones, hard shells, etc., it may be necessary to stir multiple times or increase the stirring time to achieve the desired treatment effect.

[0004] Secondly, a large number of dead corners are often generated during the stirring process of these stirring structures. The kitchen waste in these dead corners may not be fully turned over and mixed, thus affecting the uniformity and efficiency of kitchen waste treatment.

[0005] In addition, there are also certain problems with the structural strength and durability of traditional stirring structures. Since the stirring structure needs to withstand a large amount of stirring force and impact force, during long-term use, problems such as deformation and fracture may occur. This not only affects the kitchen waste treatment effect but also may increase the costs of maintenance and replacement.

[0006] The utility model is studied and proposed in view of the deficiencies of the prior art. Summary of the Utility Model

[0030] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0031] Such as Figures 1 to 8As shown in the figure, the stirring structure of this embodiment includes a stirring barrel 2 and a stirring assembly. A stirring chamber 21 is provided inside the stirring barrel 2. A stirring barrel opening 20 communicating with the stirring chamber 21 is provided on the stirring barrel 2. The stirring assembly includes a stirring member 31 and a driving device 32. The stirring member 31 is arranged inside the stirring chamber 21. The driving device 32 is in transmission connection with the stirring member 31. The driving device 32 can drive the stirring member 31 to stir. An arc-shaped stirring area 210 is provided in the stirring chamber 21. The stirring member 31 includes a stirring shaft 311 and a plurality of stirring ends 312 spirally distributed along the length direction of the stirring shaft 311. The end of each stirring end 312 is close to the inner side wall of the arc-shaped stirring area 210.

[0032] Specifically, by adopting a plurality of stirring ends 312 spirally distributed along the length direction of the stirring shaft 311, the design of the stirring ends 312 increases the contact area and stirring effect of stirring. When the stirring ends rotate, they can more effectively turn over and mix kitchen waste, effectively increasing the stirring area and strength, making the stirring more uniform and efficient. And the plurality of stirring ends 312 can ensure that the kitchen waste can be subjected to stirring forces from multiple directions and angles during the stirring process, which helps to break large pieces of kitchen waste and promote the uniform mixing of kitchen waste, thereby improving the processing efficiency and achieving more uniform mixing and crushing. Moreover, the multi-angle stirring structure design with the plurality of stirring ends 312 spirally distributed on the stirring shaft 311 can more effectively cut, flip and mix the kitchen waste mixture. Combining the design that the end of each stirring end 312 is close to the inner side wall of the arc-shaped stirring area 210 helps to reduce dead corners and residues during the stirring process. During the stirring process, the stirring ends 312 can better contact and push the kitchen waste located at the edge or bottom of the stirring chamber, reducing the retention and accumulation of kitchen waste in the stirring chamber, thereby improving the usage efficiency.

[0033] Specifically, the stirring ends 312 are arranged at intervals, which can reduce the pressure of the mixture on the stirring ends 312. Compared with the existing design of the stirring ends 312 using a spiral-shaped integral blade, the design of the plurality of stirring ends 312 arranged at intervals can effectively reduce the load of the mixture on the stirring ends 312 without affecting the conveying and stirring functions of the stirring structure, and prolong the service life of the stirring ends 312.

[0034] Furthermore, when the stirring structure of the present application is applied to a kitchen waste processor with a heating assembly, the stirring ends 312 can more effectively turn over and mix the kitchen waste during rotation, enabling the heat to be more evenly transferred to the kitchen waste, which helps to avoid the problem of overheating of the bottom kitchen waste while the upper kitchen waste is not dried, and improves the drying effect.

[0035] Such as Figures 1 to 8As shown, the stirring end 312 of this embodiment includes a plurality of first auxiliary shafts 3121. Each first auxiliary shaft 3121 includes a shaft body 3122 and a paddle 3123 provided at one end of the shaft body 3122. The other end of the shaft body 3122 is connected to the stirring shaft 311, and the paddle body of the paddle 3123 has a certain curvature.

[0036] Specifically, the stirring end 312 includes a plurality of first auxiliary shafts 3121. Each first auxiliary shaft 3121 includes a shaft body 3122 and a paddle 3123 provided at one end of the shaft body 3122. The paddle 3123 is used to stir the material in the stirring chamber 21. The design of the paddle 3123 is to maximize the stirring effect. Its paddle body has a certain curvature, which helps to provide greater stirring force and better hydrodynamic characteristics.

[0037] Preferably, the other end of the shaft body is connected to the stirring shaft 311. This connection can be welding, threaded connection or other types of mechanical connection methods, ensuring that the stirring end 312 is stable during the stirring process and can withstand the forces caused by stirring. Through the paddles on the stirring end 312, the kitchen waste in the stirring chamber 21 can be stirred more effectively, thereby accelerating the fermentation process. Curved paddles are usually more efficient and can provide a strong stirring effect while consuming less energy.

[0038] As Figures 1 to 8 shown, the paddle 3123 of this embodiment is in the shape of a shovel. This shape has a wide shovel surface and a certain curvature, which helps to better push and turn the kitchen waste during the stirring process, turning the kitchen waste at the bottom to the surface or pushing the kitchen waste on the surface to the bottom, realizing the uniform distribution and full contact of the kitchen waste, making the stirring more uniform and efficient. And the paddle 3123 in the shape of a shovel has sharp sides, which helps to break large pieces of kitchen waste and promote the uniform mixing of kitchen waste, achieving more uniform mixing and crushing.

[0039] Preferably, the other end of the shaft body 3122 and the stirring shaft 311 are of an integrally formed structure or a detachable connection structure, and a suitable design can be selected according to actual needs.

[0040] As Figures 1 to 8 shown, the stirring end 312 of this embodiment further includes two relatively arranged second auxiliary shafts 3124. The two second auxiliary shafts 3124 are located at both ends of the stirring shaft 311, and a plurality of the first auxiliary shafts 3121 are located between the two second auxiliary shafts 3124. This setting helps the stirring end 312 to directly act on the edge areas of the stirring chamber 21, and these areas are usually stirring dead corners where material accumulation is likely to occur.

[0041] Preferably, the second sub-shaft 3124 of the present embodiment is in a T-shape. The T-shaped second sub-shaft 3124 has a larger stirring range. The end of the T-shaped second sub-shaft 3124 can be closer to the inner wall of the arc-shaped stirring zone 210, and can enter the dead corner area of ​​the stirring chamber 21 more deeply, so as to better stir and transport the kitchen waste in the dead corners at both ends of the stirring chamber 21, thereby avoiding the accumulation of kitchen waste at both ends of the stirring chamber 21.

[0042] Preferably, the second auxiliary shaft 3124 and the stirring shaft 311 are an integrally formed structure or a detachable connection structure, and a suitable design can be selected according to actual needs.

[0043] Furthermore, since a large amount of material usually accumulates at the corners of the inner walls at both ends of the stirring chamber 21, the first sub-shaft 3121 with a paddle body having a certain curvature usually cannot stir the food waste at that location. In fact, the weight of the food waste may cause the paddle blades 2422 on the first sub-shaft 3121 to be damaged. In addition, since the first sub-shaft 3121 is designed to be detachably connected to the stirring shaft 311, the first sub-shaft 3121 is more easily affected by the weight of the material on the stirring shaft 311, resulting in position displacement or the sub-shaft falling off the stirring shaft 311, affecting the normal operation of the sub-shaft.

[0044] Preferably, the T-shaped second secondary shaft 3124 is more evenly stressed, reducing the stress concentration caused by single-point stress, thereby reducing the risk of damage to the second secondary shaft 3124 and making it less likely to be damaged. With regard to the design that the second secondary shaft 3124 is detachably connected to the stirring shaft 311, the secondary shaft is not easily affected by the weight of the material on the stirring shaft 311, and is not easily displaced or falls off the stirring shaft 311, thereby ensuring the normal operation of the secondary shaft.

[0045] like Figures 1 to 8 As shown, the projection of the arc-shaped stirring zone 210 of this embodiment is circular or elliptical, and the projection of the stirring member 31 is butterfly-like.

[0046] Specifically, the arc-shaped stirring zone 210 with a circular or elliptical projection helps to form a uniform stirring path, ensuring that the movement trajectory of the stirring element 31 in the entire stirring chamber 21 is evenly covered, avoiding dead corners and blind spots. This design can make the material evenly stressed during the stirring process, reduce the situation of insufficient mixing, and ensure consistent stirring effect.

[0047] Furthermore, a circular or elliptical stirring zone can promote the natural flow of materials, allowing them to circulate more smoothly in the stirring chamber and avoid accumulation and blockage. This shape helps to form a stable fluid dynamic environment, making it easier for materials to be driven and turned by the stirring element, thereby improving stirring efficiency.

[0048] Furthermore, circular or elliptical structures have better mechanical properties, can disperse and withstand pressure more evenly during the stirring process, reduce the wear and deformation of the stirring chamber wall, enhance the stability and durability of the entire stirring device, and extend the service life of the equipment.

[0049] Specifically, the stirring member with a butterfly-shaped projection has a larger surface area and diverse shape edges, which can increase the contact area with the material during the stirring process, improve the stirring efficiency, and this shape can more effectively cut and flip the material, making the stirring process more thorough and the mixing effect better.

[0050] The stirring member with a butterfly-shaped projection is not only highly functional but also more visually appealing, enhancing the overall aesthetics of the equipment. The aesthetic design can also improve the user experience and satisfaction, increasing the market competitiveness of the product.

[0051] As Figures 4 to 8 shown, the food waste processor of this embodiment includes a housing 1 and the stirring structure described in any one of the above, the housing is provided with a housing inner cavity 10, the stirring barrel 2 and the driving device 32 are both located in the housing inner cavity 10, and the stirring shaft 311 passes through both sides of the stirring barrel 2 and is connected to the driving device 32 so that the stirring end 312 flips the food waste upward along the stirring shaft 311.

[0052] The food waste processor of the present utility model reduces the jamming phenomenon caused by foreign objects between the stirring member and the stirring barrel by providing an arc-shaped stirring area 210 in the stirring chamber 21 and arranging a stirring end 312 on the stirring member 31 close to the inner side wall of the arc-shaped stirring area 210, making the stirring action smoother. The stirring member flips the food waste upward along the stirring shaft. Specifically, when encountering larger or irregular food waste, compared with the way of horizontally rotating and stirring around a vertical axis, the food waste in the corners will not be fully stirred. The arc-shaped stirring end can better adapt to and push the food waste to move, and the food waste at the bottom and corners of the stirring barrel can be fully stirred, thereby improving the stirring efficiency and uniformity and avoiding the problem that some food waste is not fully processed by the traditional stirring method.

[0053] Specifically, the jamming phenomenon caused by foreign objects between the stirring member and the stirring barrel is reduced, thereby improving the reliability of the treatment and the service life of the food waste processor.

[0054] In addition, the stirring shaft passes through both sides of the stirring barrel and is connected to the driving device, reducing the contact area between the stirring component and the inner wall of the stirring barrel, reducing the risk of the stirring component being jammed by foreign objects, and ensuring the stable operation and long service life of the stirring component.

[0055] Specifically, in some other embodiments, the food waste processor further includes a heating component, which is used to heat the arc-shaped stirring area 210. The heating component is used to heat the food waste bucket to evaporate the moisture of the food waste. The stirring member flips the food waste upward along the stirring shaft from the bottom, so that heat can be more evenly transferred to the stirring cavity, avoiding the peculiar smell caused by local high-temperature burning and further improving the user experience.

[0056] The arc-shaped stirring area is heated by the heating component, and the stirring member flips the food waste upward along the stirring shaft from the bottom, ensuring that the food waste is fully mixed and flipped during the heating process, so that heat can be more evenly transferred to the food waste in the stirring cavity, avoiding the peculiar smell caused by the high-temperature burning of the bottom food waste. Since the heat distribution is more uniform, the food waste can be more thoroughly dehydrated during the drying process, improving the processing efficiency.

[0057] As Figures 4 to 8 shown, the stirring bucket 2 of this embodiment is provided with a diversion end 22 located between the opening 20 of the stirring bucket and the stirring cavity 21. The diversion end 22 is inclined from top to bottom and from the outside of the stirring cavity 21 to the inside of the stirring cavity 21.

[0058] Furthermore, the inclined diversion end enables the material to slide naturally along the diversion end when entering the stirring cavity, reducing the accumulation and blockage of the material at the opening of the stirring bucket, and reducing the vibration and noise generated by the impact of the material on the stirring bucket wall.

[0059] In addition, for materials with high viscosity or easy to agglomerate, the design of the diversion end helps to guide the material to form a more uniform distribution in the stirring cavity, enabling the stirring component to more effectively stir and mix the material, and helping to improve the uniformity and efficiency of stirring.

[0060] As Figures 4 to 8 shown, the housing 1 of this embodiment is provided with a limiting bracket 7 for limiting the stirring bucket 2. The stirring bucket 2 is provided with a first limit line 24 and a second limit line 25. The highest stirring point of the stirring end 312 is located between the first limit line 24 and the second limit line 25.

[0061] Furthermore, as a preferred implementation manner rather than a limitation of the present utility model, the limiting bracket ensures that the stirring bucket will not deviate from the normal position or impact the housing due to excessive movement during the stirring process, thus avoiding the failure caused by the displacement of the stirring bucket. Limiting the highest point position of the stirring end during the stirring process to prevent it from hitting the top of the stirring bucket or other components, protecting the integrity of the stirring component and extending the service life of the food waste processor.

[0062] Specifically, by setting the first limit line and the second limit line, the movement range of the stirring end in the stirring barrel can be precisely controlled, ensuring the stability and consistency during the stirring process. Within the defined stirring range, the stirring end can more effectively stir and mix the materials, improving the uniformity and efficiency of stirring and avoiding problems such as local over-stirring or insufficient stirring.

[0063] Optionally, in some embodiments, the limit bracket can be fixed to the stirring barrel through fasteners.

[0064] Optionally, in some embodiments, the stirring shaft can pass through the stirring barrel and be connected to the limit bracket for limiting, further improving the stability of rotation.

[0065] Embodiment 1

[0066] As Figures 1 to 8 shown, the implementation manner of Embodiment 1 is as follows:

[0067] A kitchen waste processor includes a housing 1, the housing is provided with a housing inner cavity 10, a stirring barrel 2 located in the housing inner cavity 10, a housing opening 11 for assembling the stirring barrel 2 into the housing inner cavity 10, and a stirring assembly 3. The stirring barrel 2 is provided with a stirring barrel opening 20 connected to the housing opening 11 and a stirring cavity 21 communicated with the stirring barrel opening 20. The stirring assembly 3 includes a stirring member 31 disposed in the stirring cavity 21 and a driving device 32 for driving the stirring member 31 to stir. The stirring cavity 21 is provided with an arc-shaped stirring area 210. The stirring member 31 includes a stirring shaft 311 and a plurality of stirring ends 312 spirally distributed along the length direction of the stirring shaft 311. The end of each stirring end 312 is close to the inner side wall of the arc-shaped stirring area 210. The stirring shaft 311 passes through both sides of the stirring barrel 2 and is connected to the driving device 32 so that the stirring ends 312 turn the kitchen waste upward along the stirring shaft 311.

[0068] The stirring end 312 includes a plurality of first sub-shafts 3121. Each first sub-shaft 3121 includes a shaft body 3122 and a paddle 3123 provided at one end of the shaft body 3122. The other end of the shaft body 3122 is connected to the stirring shaft 311, and the paddle body of the paddle 3123 has a certain curvature.

[0069] The stirring barrel 2 is provided with a guiding end 22 located between the stirring barrel opening 20 and the stirring cavity 21. The guiding end 22 is inclined from top to bottom and from the outside of the stirring cavity 21 to the inside of the stirring cavity 21.

[0070] The housing 1 is provided with a limiting bracket 7 for limiting the mixing barrel 2. The mixing barrel 2 is provided with a first limiting line 24 and a second limiting line 25. The highest mixing point of the mixing end 312 is located between the first limiting line 24 and the second limiting line 25.

[0071] Specifically, by providing an arc-shaped mixing area 210 in the mixing chamber 21, and arranging a plurality of mixing ends 312 spirally distributed along the length direction of the mixing shaft 311 on the mixing member 31, and the end of each mixing end 312 is close to the inner side wall of the arc-shaped mixing area 210. With such a design that a plurality of mixing ends 312 are spirally and spacedly distributed on the mixing shaft 311, the jamming phenomenon caused by foreign objects between the mixing member 31 and the mixing barrel 2 is reduced, making the mixing action smoother. By adopting a plurality of mixing ends 312 spirally distributed along the length direction of the mixing shaft 311, the design of the mixing ends 312 increases the mixing contact area and mixing effect. When the mixing ends rotate, they can more effectively turn over and mix food waste, effectively increasing the mixing area and strength, making the mixing more uniform and efficient. And a plurality of mixing ends 312 can ensure that the food waste can be subjected to mixing forces from multiple directions and angles during the mixing process, which helps to break large pieces of food waste and promote the uniform mixing of food waste, thereby improving the processing efficiency and achieving more uniform mixing and crushing. Moreover, the multi-angle mixing structure design in which a plurality of mixing ends 312 are spirally distributed on the mixing shaft 311 can more effectively cut, turn over and mix the food waste mixture. Combining the design that the end of each mixing end 312 is close to the inner side wall of the arc-shaped mixing area 210 helps to reduce the dead corners and residues during the mixing process. During the mixing process, the mixing ends 312 can better contact and push the food waste located at the edge or bottom of the mixing chamber, reducing the retention and accumulation of food waste in the mixing chamber, thereby improving the use efficiency.

[0072] Embodiment 2

[0073] The difference between Embodiment 2 and Embodiment 1 is that the food waste processor further includes a heating component for heating the arc-shaped mixing area 210. The heating component is used to heat the food waste barrel to evaporate the moisture of the food waste. The mixing member flips the food waste from bottom to top along the mixing shaft, so that the heat can be more evenly transferred to the mixing chamber, avoiding the peculiar smell caused by local high temperature burning and further improving the user experience.

[0074] By heating the arc-shaped mixing area with the heating component and the mixing member flipping the food waste from bottom to top along the mixing shaft, it is ensured that the food waste is fully mixed and flipped during the heating process, so that the heat can be more evenly transferred to the food waste in the mixing chamber, avoiding the peculiar smell caused by the high temperature burning of the bottom food waste. Since the heat distribution is more uniform, the food waste can more thoroughly remove moisture during the drying process, improving the processing efficiency.

[0075] Example 3

[0076] The difference between Example 3 and Example 1 is that the stirring end 312 further includes two oppositely arranged second auxiliary shafts 3124. The two second auxiliary shafts 3124 are located at both ends of the stirring shaft 311, and a plurality of the first auxiliary shafts 3121 are located between the two second auxiliary shafts 3124. This setting helps the stirring end 312 directly act on the edge area of the stirring cavity 21, and these areas are usually dead corners of stirring, which are prone to material accumulation.

[0077] Preferably, the second auxiliary shaft 3124 in this embodiment is in a T shape. The T-shaped second auxiliary shaft 3124 has a larger stirring range. The end of the T-shaped second auxiliary shaft 3124 can be closer to the inner wall of the arc-shaped stirring area 210, and can enter the dead corner area of the stirring cavity 21 more deeply, and can better stir and transport the kitchen waste at both dead corners of the stirring cavity 21, avoiding the accumulation of kitchen waste at both ends of the stirring cavity 21.

[0078] Example 4

[0079] On the basis of Example 4, Example 3 has the following implementation manner: the projection of the arc-shaped stirring area 210 is oval, and the projection of the stirring member 31 is in a shape similar to a butterfly.

[0080] The above only uses examples to further illustrate the technical content of the present invention to make it easier for readers to understand, but it does not mean that the implementation manners of the present invention are limited to this. Any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
