Description

Technical Field

[0001] This utility model relates to the technical field of household appliance equipment, and in particular to a stirring structure applied to food processing equipment and the food processing equipment. Background Technology

[0002] In modern kitchens and the food processing industry, the mixing structure on food processing equipment (such as stir-fry machines or kitchen waste disposers) plays a crucial role. However, existing mixing shaft assemblies often have a significant problem during use: they cannot effectively drive the movement of material near the inner wall of the food processing shell. This problem is mainly manifested in the fact that material tends to accumulate or remain near the inner wall of the food processing shell, thus affecting the uniformity of mixing and the cleanliness of the equipment.

[0003] Traditional mixing shaft assemblies are typically designed to be located at the center of the food processing shell and to move materials through rotation. However, due to the distance between the mixing shaft and the inner wall of the shell, and the fact that the design of the mixing blades often cannot completely cover the entire inner surface of the shell, it is difficult for the material near the inner wall to be fully moved and mixed. This unmoved material will gradually accumulate on the inner wall of the shell during the mixing process, forming a layer of residue.

[0004] This residue not only affects the uniformity and quality of the final food, but also increases the difficulty of cleaning, especially when dealing with some viscous or sticky materials, where the problem is more pronounced.

[0005] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0006] The aforementioned technical problem addresses the issue that existing stirring shaft assemblies cannot effectively move the material near the inner wall of the food processing shell during use, causing the material to easily accumulate or remain near the inner wall of the food processing shell, thus affecting the uniformity of stirring and the cleanliness of the equipment.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A stirring structure for use in food processing equipment includes a stirring shaft assembly disposed within a food processing housing. The stirring shaft assembly includes a main shaft, an auxiliary blade assembly, and a secondary shaft. There are multiple secondary shafts, which are spaced apart along the shaft of the main shaft. The two ends of each secondary shaft are connected to the main shaft and the auxiliary blade assembly, respectively. The auxiliary blade assembly is helical in shape and has a certain distance from the sidewall of the secondary shaft to form a through hole.

[0009] As described above, in a stirring structure applied to a food processing device, the auxiliary blade assembly is a one-piece molded structure.

[0010] As described above, in a stirring structure applied to a food processing device, the auxiliary blade assembly has a circular cross-section.

[0011] As described above, in a stirring structure applied to a food processing device, the auxiliary blade assembly has a circular or elliptical projected shape, and the structure formed by combining multiple secondary shafts has a cross-shaped or star-shaped projected shape.

[0012] As described above, in a stirring structure applied to a food processing device, each of the secondary shafts includes a main shaft connecting section and an auxiliary blade assembly connecting section connected in sequence, wherein the angle between the central axis of the main shaft connecting section and the central axis of the auxiliary blade assembly connecting section is an acute angle or a right angle.

[0013] As described above, in a stirring structure applied to a food processing device, the auxiliary blade assembly connecting section is inclined on the main shaft connecting section so that there is a certain angle between the auxiliary blade assembly connecting section and the rotation direction of the main shaft.

[0014] As described above, a stirring structure applied to a food processing device has an assembly plane on the main shaft corresponding to the main shaft connecting section. A connecting member is provided between the main shaft connecting section and the assembly plane. The assembly plane can abut against the main shaft connecting section, and the connection is achieved through the connecting member.

[0015] As described above, in a stirring structure applied to a food processing device, the main shaft is further provided with end stirring blades at both ends, which can stir the material near the inner side of the end of the food processing housing.

[0016] A food processing device includes a food processing housing and a stirring structure as described in any of the above claims, wherein the food processing housing has a stirring chamber and the stirring shaft assembly is disposed within the stirring chamber.

[0017] As described above, in a food processing device, the mixing chamber includes a feeding zone and an arc-shaped mixing zone, and the auxiliary blade assembly is close to the inner wall of the arc-shaped mixing zone.

[0018] The beneficial effects of this utility model are:

[0019] This utility model relates to a stirring structure and food processing equipment, which pertain to the technical field of household appliances. The stirring structure employs a spiral auxiliary blade assembly design, creating a rolling effect within the food processing housing. Utilizing the principle of spiral propulsion, the material flows along the spiral trajectory of the blade assembly during stirring. This flow effectively promotes mixing and tumbling of the material, allowing it to not only tumble but also change its flow state, resulting in a rolling effect within the food processing housing. This rolling motion ensures more uniform mixing within the housing, enabling thorough mixing and processing in a short time. Furthermore, the through-hole between the auxiliary blade assembly and the secondary shaft reduces the resistance of the material to the stirring shaft assembly, giving the stirring structure the advantage of high structural strength.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, a stirring structure applied to a food processing device according to this embodiment includes a stirring shaft assembly 200 disposed in a food processing housing 100. The stirring shaft assembly 200 includes a main shaft 21, an auxiliary blade assembly 23, and a secondary shaft 22. There are multiple secondary shafts 22, which are spaced apart along the shaft of the main shaft 21. The two ends of each secondary shaft 22 are respectively connected to the main shaft 21 and the auxiliary blade assembly 23. The auxiliary blade assembly 23 is spiral in shape.

[0032] Specifically, the design of the spiral auxiliary blade assembly 23 creates a rolling effect within the food processing shell 100. Utilizing the principle of spiral propulsion, the material flows along the spiral trajectory of the blade assembly during the mixing process. This flow pattern effectively promotes the mixing and tumbling of the material, allowing it to not only tumble during mixing but also effectively change its flow state, resulting in a rolling effect within the food processing shell 100. Through this rolling, the material is mixed more evenly within the food processing shell 100, ensuring thorough mixing and processing in a short time.

[0033] Furthermore, because the stirring shaft assembly 200 can effectively drive the material to tumble inside the food processing housing 100, it enhances the fluidity of the material and prevents the material from accumulating and remaining on the inner wall of the food processing housing 100, thereby reducing the difficulty of cleaning the equipment and improving the convenience of operation and hygiene.

[0034] Furthermore, the auxiliary blade assembly 23 and the sidewall of the secondary shaft 22 are at a certain distance to form a through hole 25, allowing the material to pass through the stirring shaft assembly 200, reducing the resistance of the material to the stirring shaft assembly 200, making the stirring shaft assembly 200 smoother during the stirring process, and making the force distribution of the stirring shaft assembly 200 more uniform. This reduces the load on a single component, thereby enhancing the stability and strength of the overall structure. The reasonable design can reduce stress concentration generated during operation, thereby reducing the risk of material fatigue and deformation, giving the stirring structure the advantage of good structural strength and extending the service life of the equipment.

[0035] like Figures 1 to 4 As shown, the auxiliary blade assembly 23 in this embodiment is a one-piece molded structure. This one-piece design effectively disperses and withstands externally applied forces, allowing the auxiliary blade assembly 23 to evenly distribute the force across the entire structure during operation, rather than concentrating it at a single point. This helps improve the strength and durability of the auxiliary blade assembly 23.

[0036] Furthermore, the one-piece molding structure eliminates connection points between multiple components, enhances overall strength, thereby improving the durability of the tool set and reducing the risk of failure under high-load working conditions.

[0037] Furthermore, the shape and streamlined design of the one-piece auxiliary blade assembly 23 can optimize the flow of fluid around the auxiliary blade assembly 23, reduce interference and turbulence, and improve stirring and mixing efficiency.

[0038] Furthermore, the auxiliary blade assembly 23, through one-time molding, can reduce assembly processes and material waste, thereby reducing production costs and improving production efficiency.

[0039] like Figures 1 to 4 As shown, the cross-section of the auxiliary blade assembly 23 in this embodiment is circular, and the auxiliary blade assembly 23 in this embodiment is elongated.

[0040] Specifically, a circular cross-section can effectively reduce resistance during fluid flow, making the material flow more smoothly during mixing and improving mixing efficiency.

[0041] The elongated structure increases the contact area between the material and the mixing surface. Combined with the circular cross-section, it can achieve a more uniform mixing effect. The circular cross-section also makes the stress distribution more uniform, reducing structural weaknesses caused by stress concentration. The elongated design provides better axial stability.

[0042] Furthermore, circular cross-sections and elongated structures are generally easier to manufacture and process, reducing the manufacturing difficulties caused by complex geometries, while their simple structure makes them easy to clean and maintain.

[0043] Furthermore, the circular cross-section and elongated structure can scrape the inner wall of the food processing housing 100 without damaging it, thus extending its service life.

[0044] like Figures 1 to 4 As shown, the projected shape of the auxiliary blade assembly 23 in this embodiment is circular or elliptical, and the projected shape of the structure formed by the combination of multiple secondary shafts 22 is cross-shaped or star-shaped.

[0045] Specifically, the auxiliary blade assembly 23, with a projected circular or elliptical shape, can effectively reduce fluid resistance, making the material flow more smoothly during the mixing process. This shape helps to form a uniform flow field and avoids the formation of a mixing dead zone within the food processing shell 100, thereby improving the mixing effect.

[0046] Furthermore, the cross-shaped or star-shaped design with multiple secondary shafts can apply force in multiple directions, providing multiple auxiliary mixing points. This can increase the tumbling and dispersing of materials during the mixing process, allowing the materials to be evenly distributed during mixing and avoiding material stratification or unevenness caused by mixing in one direction, thus helping to improve mixing efficiency.

[0047] Furthermore, the cross-shaped or star-shaped design of multiple auxiliary shafts provides stronger support, making the entire stirring shaft assembly 200 more stable under high loads and reducing the risk of equipment failure.

[0048] Furthermore, the combined design of the aforementioned auxiliary tool assembly 23 and multiple sub-spindles 22 is able to

[0049] The mixing contact area of ​​the mixing shaft assembly 200 is effectively expanded, thereby improving the mixing efficiency of the material and guiding the material to form a good circulation flow during the mixing process, ensuring that each part of the material can fully participate in the mixing and blending, thereby improving the overall mixing uniformity.

[0050] The 200 stirring shaft assembly has a simple and effective structural design, which reduces the retention of materials between components, helps to reduce cleaning difficulty, and keeps the equipment hygienic.

[0051] like Figures 1 to 4 As shown, each of the sub-shafts 22 in this embodiment includes a main shaft connecting section 221 and an auxiliary blade assembly connecting section 222 connected in sequence. The angle between the central axis of the main shaft connecting section 221 and the central axis of the auxiliary blade assembly connecting section 222 is an acute angle or a right angle. This design helps the sub-shaft 22 to more effectively convert the rotational power transmitted by the main shaft into the cutting and stirring force of the auxiliary blade assembly during the stirring process, thereby optimizing the force distribution.

[0052] This angled design allows each sub-shaft 22 to cut into the material at different angles, thereby enhancing the mixing and blending effect of the material, forming a more complex flow pattern, and improving the overall mixing efficiency.

[0053] Furthermore, by changing the angle between the connecting sections, the cutting angle of the blade assembly can be flexibly adjusted to adapt to the mixing needs of different materials, thereby optimizing the mixing effect.

[0054] This angled design effectively reduces dead zones in the material during mixing, ensuring that every part of the material participates in the mixing process and avoids uneven mixing caused by dead zones.

[0055] Furthermore, the angled design can enhance the structural strength of the subshaft, reduce deformation or damage caused by force concentration, and improve the durability and stability of the equipment.

[0056] Preferably, in this embodiment, the projection shape of the secondary shaft 22 is L-shaped or L-shaped, that is, the angle between the central axis of the auxiliary blade assembly connecting section 222 and the central axis of the main shaft connecting section 221 is a right angle or nearly a right angle. This design ensures that the structural strength of the secondary shaft 22 is optimal, thus ensuring the structural strength of the stirring shaft assembly 200 and extending its service life.

[0057] like Figures 1 to 4 As shown, in this embodiment, the auxiliary blade assembly connecting section 222 is inclined on the main shaft connecting section 221 so that there is a certain angle between the auxiliary blade assembly connecting section 222 and the rotation direction of the main shaft 21, so as to form the effect of the auxiliary blade assembly connecting section 222 cutting the material, further improving the cutting effect of the secondary shaft 22 on the material. The inclined secondary shaft 22 design can change the flow pattern of the material during the mixing process, so that the material can be better turned over and dispersed under the action of the blade, forming a more complex flow field, thereby improving the mixing efficiency of the material.

[0058] By tilting the shafts, multiple secondary shafts 22 can apply force to the material at different positions. Since the tilted secondary shafts 22 can apply force to the material at different angles, the material can be better flipped and mixed, ensuring the uniformity of the final mixture. They can also increase the cutting and dispersing ability of the material, allowing the material to be broken up and mixed in a short time, reducing operation time, improving work efficiency, and effectively reducing the overall stickiness and accumulation of the material.

[0059] Furthermore, by tilting the sub-shaft 22, cutting the material requires less effort.

[0060] like Figures 1 to 4 As shown, the spindle 21 of this embodiment is provided with an assembly plane 211 corresponding to the spindle connecting section 221. A connecting member is provided between the spindle connecting section 221 and the assembly plane 211. The assembly plane 211 can abut against the spindle connecting section 221. The connection is achieved through the connecting member, so that the sub-shaft 22 can be stably assembled on the spindle 21.

[0061] Specifically, the design of the assembly plane 211 provides a stable support surface for the spindle connection section 221. The robust connection design can reduce vibration and offset generated during operation, making the connection between the two more secure and helping to improve the overall stability of the equipment.

[0062] The connection between the main shaft connecting section 221 and the assembly plane 211 via the connecting components can effectively transmit the power from the main shaft 21, ensuring that the secondary shaft 22 can stably receive and utilize these forces during operation.

[0063] Preferably, the main shaft 21 can be in the shape of a cubic column or a circular column, and an assembly plane 211 is provided on the surface of the circular column. The appropriate design can be selected according to actual needs.

[0064] Preferably, the connecting components can be welded, threaded, snap-fitted, or other methods, and a suitable design can be selected according to actual needs.

[0065] like Figures 1 to 4 As shown, a food processing device according to this embodiment includes a food processing housing 100 and a stirring structure as described in any of the above. The food processing housing 100 is provided with a stirring chamber 101, and the stirring shaft assembly 200 is disposed in the stirring chamber 101. The material in the stirring chamber 101 is stirred by a spiral auxiliary blade assembly 23. The spiral auxiliary blade assembly 23 is designed to utilize the principle of spiral propulsion, so that the material can flow along the spiral trajectory of the blade assembly during the stirring process. This flow mode can effectively promote the mixing and turning of the material.

[0066] During the mixing process, the spiral-shaped auxiliary blade assembly 23 not only cuts and mixes the material, but also generates an upward thrust through its spiral shape, causing the material to roll within the cavity. This motion helps the material to be distributed and mixed more evenly.

[0067] The spiral auxiliary blade assembly 23 is designed to create a constantly changing flow field, so that the material is subjected to forces in different directions during the mixing process, thereby improving the material movement efficiency and cutting effect.

[0068] With the design of the spiral blade assembly, the materials can be fully mixed in the mixing chamber, ensuring the uniformity between different components. The rolling effect formed during the mixing process can accelerate the transfer and mixing of materials, reduce mixing time, and improve overall work efficiency. The mixing effect of food processing equipment using the spiral auxiliary blade assembly 23 is even better.

[0069] like Figures 1 to 4 As shown, the mixing chamber 101 of this embodiment includes a feeding area 102 and an arc-shaped mixing area 103. The auxiliary blade assembly 23 is close to the inner wall of the arc-shaped mixing area 103. The design of the arc-shaped mixing area 103 can effectively guide the flow path of the material, so that the material forms a circulating flow along the arc-shaped inner wall during the mixing process. This flow mode can reduce dead corners and improve the mixing efficiency of the material.

[0070] The proximity design between the auxiliary blade assembly 23 and the inner wall of the arc-shaped mixing zone 103 ensures that the blade assembly can more effectively contact the material during operation, thereby improving the cutting, mixing, and blending effects. The closer distance allows the blade assembly to better utilize its power.

[0071] The arc-shaped mixing zone 103, combined with the efficient auxiliary blade assembly 23, can effectively reduce the retention of materials in the mixing chamber, ensuring that all materials can be fully mixed and processed. This design allows the materials to be fully turned over and mixed in the arc-shaped mixing zone, thereby improving the uniformity of mixing and ensuring the consistency and quality of the finished product.

[0072] Due to the arc-shaped structure of the arc-shaped mixing zone 103, the material can flow more smoothly during the mixing process, reducing the possibility of clogging and improving the working efficiency of the equipment.

[0073] Preferably, the spiral auxiliary blade assembly 23 rolls the material in the entire mixing chamber 101, causing the material to tumble and further improving the mixing effect.

[0074] Furthermore, when the stirring structure of this application is applied to a food processing device with a heating component, the heating component is used to heat the arc-shaped stirring zone 103. Taking a food processing device as a kitchen waste processor as an example, the heating component is used to heat the food processing shell 100 to evaporate the moisture of the kitchen waste. The kitchen waste is turned over by the spiral auxiliary blade assembly 23, so that the heat can be transferred to the stirring chamber more evenly, avoiding the odor caused by local high temperature burning, and further improving the user experience.

[0075] The heating element heats the arc-shaped mixing zone, while the spiral auxiliary blades 23 tumble the food waste, ensuring that the food waste is fully mixed and turned during the heating process. This allows the heat to be transferred more evenly to the food waste in the mixing chamber, avoiding the odor caused by the food waste at the bottom burning at high temperatures. Because the heat distribution is more even, the food waste can be dried more thoroughly, improving processing efficiency.

[0076] Example 2:

[0077] The difference between Example 2 and Example 1 is as follows:

[0078] like Figures 5 to 8 As shown, the main shaft 21 in this embodiment is also provided with end stirring blade assembly 24 at both ends. The end stirring blade assembly 24 can stir the material near the inner side of the end of the food processing shell 100. With this design, not only can the material in the middle be effectively stirred and cut, but also the material at both ends of the shell is taken into account, effectively preventing the material from accumulating at both ends of the processing shell 100, realizing full coverage of the entire processing space, avoiding dead corners and material accumulation, thereby improving processing efficiency and effect.

[0079] Preferably, the end agitator assembly 24 of this embodiment includes a transverse section 241 connected to the main shaft 21 and a vertical section 242 that is close to or abuts against the inner sidewall of the end of the food processing housing 100. The vertical section 242 can ensure that the end agitator assembly 24 can agitate the material near the inner side of the end of the food processing housing 100.

[0080] Preferably, the end agitator assembly 24 in this embodiment further includes an arc-shaped segment 243 disposed between the transverse segment 241 and the vertical segment 242. The introduction of the arc-shaped segment 243 makes the structure of the end agitator assembly 24 more streamlined, reducing the obstruction that sharp edges and abrupt structures may cause to the material flow, thereby achieving a smoother stirring effect.

[0081] Specifically, the arc-shaped section 243 provides a smooth transition between the transverse section 241 and the vertical section 242. This gentle transition can reduce the concentration of mechanical stress during the mixing process, improve the structural strength and durability of the blade assembly, and the streamlined design of the arc-shaped section 243 can reduce the resistance encountered by the material during the mixing process, reduce energy consumption, and reduce noise caused by sudden turns and structural changes.

[0082] Furthermore, the presence of the arc-shaped segment 243 increases the coverage area of ​​the blade assembly in space, enabling it to more comprehensively contact and agitate the material, especially to more effectively handle the material at the edges and corners of the shell, thus improving the processing effect in these areas.

[0083] Preferably, the end agitator blade assembly 24 is made of a soft material, and the soft blades can scrape the two ends of the food processing housing 100 so that the material does not stick to the two ends of the food processing housing 100.

[0084] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
