Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a food processing machine. Background Art

[0002] The existing soybean milk machine includes a machine head and a cup body. The machine head is provided with a crushing blade, and soybeans are crushed by the crushing blade to make soybean milk. Generally, a crushing cover is provided at the front end of the machine head to improve the crushing efficiency. For example, the application No. 201320270565.2 discloses a soybean milk machine safety machine head, in which a connector is fixedly provided at the lower end of the machine head lower cover, a spoiler curved surface body is fixedly provided at the lower end of the connector, and a scratch-proof part is provided at the lower end of the spoiler curved surface body to increase the contact area of ​​the spoiler curved surface body to avoid scratching the table surface. However, since the spoiler curved surface realizes the circulation of materials inside and outside the spoiler curved surface through the guide hole that plays a guiding role, this causes pulp residue to remain at the guide hole to form a cleaning dead angle, and there is pulp adhesion on the surface of the spoiler curved surface. If it is not cleaned in time, it will cause the pulp residue to scab, and the cleaning is not thorough.

[0003] Application No. CN201020578703.X discloses a head structure of a soybean milk machine, which reduces cleaning dead angles by opening the grinder in a cylindrical or trumpet shape at the bottom and spirally or obliquely setting a diversion opening on the grinder surface, thereby avoiding the problem of material jamming and slag accumulation that is difficult to clean caused by setting a diversion hole. However, the inventor found in the process of studying the patent that after the soybean milk machine is finished, the user generally places the head on the work surface, and the head is supported on the work surface by the grinder. The contact area between the grinder and the work surface is limited. The spiral diversion opening on the surface of the grinder causes the grinder to be easily deformed under the pressure of the head. In addition, if a coating is set on the surface of the grinder, the gripping force of the coating is insufficient due to the small position area of ​​the grinder support part. When the grinder frequently contacts and collides with the work surface, the coating is easily caused to fall off, causing a lot of trouble for consumers. Utility Model Content

[0004] The utility model provides a food processing machine, which optimizes the structure of a crushing cover, solves the problem of residue accumulation and difficulty in cleaning of the crushing cover in the prior art due to the provision of guide holes, and further solves the problem of easy shedding of the coating on the surface of the crushing cover.

[0005] The technical solution adopted by the utility model is:

[0006] A food processing machine comprises a cup body and a machine head mounted on the cup body, the machine head comprises a metal lower cover, a crushing cover is arranged at the front end of the metal lower cover, a motor is arranged inside the metal lower cover, a rotating shaft driven by the motor passes through the metal lower cover and extends into the crushing cover, a crushing blade is installed at the front end of the rotating shaft, the surface of the crushing cover is coated with a non-stick coating, the side wall of the crushing cover has a plurality of baffles arranged at intervals along the circumferential direction, and an overflow gap is formed between two adjacent baffles, a horizontally extending supporting plane is arranged at the bottom end of a single baffle, the supporting planes of the plurality of baffles are flush, and the area of ​​a single supporting plane is S, satisfying S≥2mm 2 .

[0007] The food processing machine provided by the utility model realizes centralized crushing by providing a crushing cover, thereby improving the efficiency of crushing and the taste of soy milk. By coating the surface of the crushing cover with a non-stick coating, the probability of slurry adhesion can be reduced, and cleaning is easy. The side wall of the crushing cover has a plurality of baffles arranged at intervals along the circumference, and an overflow gap is formed between two adjacent baffles. The overflow gap is used to realize the internal and external circulation of materials relative to the crushing cover, so as to realize material circulation crushing. Compared with the method of using guide holes in the traditional technology, it effectively avoids the phenomenon of material jamming and the phenomenon of materials hiding in the guide holes, thereby realizing thorough and uniform crushing, facilitating cleaning, and further realizing thorough cleaning of the crushing cover. On this basis, by providing a horizontally extending support plane at the bottom end of a single baffle, the support planes of the multiple baffles are flush, so as to realize the stable placement of the machine head, and the area S of a single support plane is ≥ 2mm 2 On the one hand, ensure that the non-stick coating has enough adhesion area, the non-stick coating and the baffle have a strong grip, especially on the supporting plane, the coating is more solid, and the paint peeling causes the problem of cleaning dead corners and unsightly appearance. On the other hand, the area of ​​the supporting plane is not less than 2mm 2 When the machine head is supported on the work surface by the crushing cover, the contact area between the supporting plane and the work surface is large and the pressure is small, which reduces the risk of deformation of the bottom of the crushing cover, further prevents the non-stick coating from falling off, facilitates cleaning, and extends the service life of the crushing cover and the machine head.

[0008] In a preferred embodiment, the crushing cover is formed by aluminum casting, and the radial width of the supporting plane is W, satisfying W≥1.5 mm.

[0009] The crushing cover adopts aluminum casting process, which is convenient for manufacturing and processing to prepare the crushing cover of the required shape according to actual needs, and meet the radial width W ≥ 1.5mm of the supporting plane. It is not only conducive to the non-stick coating of the supporting plane to have sufficient grip and firm coating, but also can avoid deformation of the bottom of the crushing cover, and further avoid the non-stick coating on the crushing cover from falling off.

[0010] In a preferred embodiment, the crushing cover and the metal lower cover are integrally formed.

[0011] The assembly process of the machine head is simplified, the assembly efficiency is improved, and the matching gap between the crushing cover and the metal lower cover is avoided, thereby avoiding the risk of coating falling off at the contact part, preventing the coating from falling off, and slag is hidden in the matching gap for easy cleaning.

[0012] In a preferred embodiment, the support plane is connected to the inner side surface or the outer side surface of the baffle plate via a fillet, and the radius of the fillet is r, satisfying: r≥0.2 mm.

[0013] By connecting the support plane to the inner side or outer side of the baffle plate through a rounded corner, and the radius of the rounded corner is r ≥ 0.2 mm, the formation of sharp corners at the connection position between the support plane and the side wall of the baffle plate is avoided, thereby preventing the non-stick coating at the corner connection between the side wall of the baffle plate and the bottom wall from falling off.

[0014] In a preferred embodiment, the radius of the fillet is r, satisfying 0.3mm≤r≤1.5mm.

[0015] Due to the limited thickness of the baffle plate, if the radius of the fillet r is too large, greater than 1.5mm, it may occupy a larger space on the bottom wall of the baffle plate, resulting in insufficient area for setting the support plane, and the size of the support plane is difficult to reach the required size, causing the bottom coating to easily fall off. If the circumferential width of the baffle plate is increased, it will also affect the opening area of ​​the flow gap and affect the circulation and crushing of the material. In addition, r is not less than 0.3mm, which can ensure that the fillet has sufficient curvature under the premise of limited thickness of the baffle plate to prevent the risk of coating falling off due to connecting edges. Therefore, satisfying 0.3mm≤r≤1.5mm can not only avoid the falling off of the non-stick coating on the support plane, but also ensure the falling off of the non-stick coating at the connection between the side wall and the bottom wall of the baffle plate, so that the coating on the entire surface of the crushing cover can be firmly adhered and the structure is reliable.

[0016] In a preferred embodiment, the inner side surface of the baffle is an inwardly convex arc surface.

[0017] By setting the inner side of the baffle plate to an inwardly protruding arc surface, when the material in the crushing cover is cut by the crushing blade by rotation, the material will quickly rebound to the crushing blade in different directions after colliding with the inner side of the baffle plate, and the rebounded material will be cut again, so as to achieve cyclic crushing and improve the crushing efficiency. Preferably, the outer side of the baffle plate is set to an outwardly protruding arc surface, and the material flowing out of the crushing cover through the flow gap will move along the outwardly protruding arc surface under the rotating stirring action of the liquid flow, and will collide with the side wall of the cup body and rebound during the movement, and the rebounded material will be crushed again through the crushing cover, so the material outside the crushing cover can quickly enter the crushing cover again for cutting, which accelerates the crushing process and improves the crushing efficiency and crushing effect.

[0018] In a preferred embodiment, the baffle includes a main body and a thickened portion connected to the lower end of the main body and having a wall thickness increased relative to the main body, the main body and the thickened portion are connected via a step surface, and the support plane is arranged on the bottom end surface of the thickened portion.

[0019] The baffle includes a main body and a thickened portion, and the thickened portion further prevents the coating of the supporting plane from falling off. Moreover, since a motor is arranged inside the machine head, a "top-heavy" phenomenon will occur when the machine head is supported on the work surface by the crushing cover. Therefore, by providing a thickened portion with increased wall thickness, the main body and the thickened portion are connected by a step surface, which can improve the support stability of the machine head from both the weight of the crushing cover and the support area, and prevent the machine head from tipping over. At the same time, the thickened portion provides sufficient setting space for the supporting plane, achieves a good adhesion effect of the non-stick coating, increases the difficulty of deformation, and prevents the non-stick coating from falling off.

[0020] In a preferred embodiment, the thickness of the baffle gradually increases from the top end to the bottom end.

[0021] The thickness of the baffle plate gradually increases from the top to the bottom, so that the non-stick coating can be firmly attached to the bottom supporting plane of the baffle plate. On this basis, the thickness of the baffle plate gradually increases, effectively avoiding the formation of angled surfaces on the surface of the baffle plate, reducing the risk of coating falling off, and avoiding dead corners for residue accumulation caused by flanged edges, reducing the risk of residue accumulation and making it easier to clean thoroughly.

[0022] In a preferred embodiment, 4 to 8 baffles are provided.

[0023] By setting the number of baffles to 4-8, multiple baffles can reliably gather the materials in the crushing cover to achieve the effect of centralized crushing. At the same time, multiple flow gaps between the multiple baffles can be used to achieve cyclic crushing of the materials and improve the crushing efficiency.

[0024] In a preferred embodiment, the flow gap has an arc-shaped profile and forms a wave crest at the upper end.

[0025] By setting the upper end of the flow gap to an arc shape and forming a wave crest, the flow direction of the material changes during the process of entering and exiting the flow gap, which has a disturbing effect, preventing the material from flowing out in a uniform direction and increasing the probability of collision between the material and the crushing blade. At the same time, the arc-shaped profile avoids the formation of a dead corner for slag at the top of the flow gap, making it easier to thoroughly clean the crushing cover.

[0026] In a preferred embodiment, a crest is formed at the upper end of the contour of the flow gap, and the flow gap includes a first flow gap with a height of H1 from the crest to the top wall of the crushing cover and a second flow gap with a height of H2 from the crest to the top wall of the crushing cover, and the first flow gap and the second flow gap are alternately arranged along the circumference of the crushing cover, and H1<H2.

[0027] The height H1 from the wave crest of the first flow gap to the top wall of the crushing cover is less than the height H2 from the wave crest of the second flow gap to the top wall of the crushing cover. The first flow gap and the second flow gap are arranged alternately, so as to form a wavy profile at the bottom of the crushing cover, and the height of the wave crest of the wavy profile is different, so that the liquid flows flowing out of different flow gaps have a pressure difference, and the liquid flow between the outer side of the crushing cover and the side wall of the cup body rotates and flows, which promotes the mixing of liquid flows at different heights, and then effectively mixes the liquid on the outer side of the crushing cover, which is beneficial to ensure the consistency of the crushing rate, improve the circulation effect, and thus improve the crushing effect. The alternating arrangement of the first flow gap and the second flow gap is also beneficial to the dynamic balance of the crushing blade when whipping the liquid flow, so that the machine head will not shake or vibrate significantly during the beating of the crushing blade.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0041] like Figure 1 As shown, the utility model provides a food processing machine in one embodiment, including a cup body 10 and a head 20 installed on the cup body 10, the head 20 includes an upper cover 22 and a metal lower cover 21, the upper cover 22 and the metal lower cover 21 together form an installation cavity 23 for installing a motor 24, a crushing cover 30 is arranged at the front end of the metal lower cover 21, a motor 24 is arranged in the metal lower cover 21, a rotating shaft driven by the motor 24 passes through the metal lower cover 21 and extends into the crushing cover 30, a crushing blade 25 is installed at the front end of the rotating shaft, the surface of the crushing cover 30 is coated with a non-stick coating, the side wall of the crushing cover 30 has a plurality of baffles 31 arranged at intervals along the circumferential direction, and an overflow gap 32 is formed between two adjacent baffles 31, a horizontally extending support plane 33 is arranged at the bottom end of a single baffle 31, the support planes 33 of the plurality of baffles 31 are flush, and the area of ​​a single support plane is S, satisfying S≥2mm 2 .

[0042] Specifically, the crushing hood 30 is formed by aluminum casting, and the radial width of the support plane is W, satisfying W ≥ 1.5 mm. Among them, the crushing hood 30 is integrally formed with the metal lower cover 21, and the non-stick coating is a ceramic coating. The crushing hood and the metal lower cover are integrally formed, which can further avoid the generation of installation gaps between the crushing hood and the metal lower cover, avoid the occurrence of slag dead corners, and facilitate cleaning. Of course, it should be noted that the utility model is not limited to the method of integrally forming the crushing hood and the metal lower cover. In fact, the crushing hood can be fixed to the bottom end of the metal lower cover in a split manner by fasteners or the like, so as to realize flexible disassembly, assembly, maintenance or replacement of the crushing hood.

[0043] The food processing machine provided by the utility model realizes centralized crushing by providing a crushing cover 30, thereby improving the efficiency of crushing and the taste of soy milk. By coating the surface of the crushing cover 30 with a non-stick coating, the probability of slurry adhesion can be reduced, and cleaning is easy. The side wall of the crushing cover 30 has a plurality of baffles 31 arranged at intervals along the circumferential direction, and an overflow gap 32 is formed between two adjacent baffles 31. The overflow gap 32 is used to realize the internal and external circulation of materials relative to the crushing cover 30, so as to realize the circulating crushing of materials. Compared with the method of using guide holes in the traditional technology, it effectively avoids the phenomenon of material jamming and the phenomenon of materials hiding in the guide holes, thereby realizing thorough and uniform crushing, facilitating cleaning, and further realizing thorough cleaning of the crushing cover 30. On this basis, by providing a horizontally extending support plane 33 at the bottom end of a single baffle 31, the support planes 33 of the plurality of baffles 31 are flush, so as to realize the stable placement of the machine head 20, and the area S of a single support plane 33 is ≥ 2 mm 2 On the one hand, it ensures that the non-stick coating has enough adhesion area, and the non-stick coating and the baffle 31 have a strong grip, especially at the support plane 33, so that the coating is more firmly applied, and the problem of cleaning dead corners and unsightly appearance caused by paint falling off is avoided. On the other hand, the area of ​​the support plane 33 is not less than 2mm 2 When the machine head 20 is supported on the work surface 40 through the crushing cover 30, the contact area between the supporting plane 33 and the work surface is large and the pressure is small, which reduces the risk of deformation of the bottom end of the crushing cover 30, further prevents the non-stick coating from falling off, facilitates cleaning, and extends the service life of the crushing cover 30 and the machine head 20.

[0044] In a preferred embodiment, the support plane is connected to at least one of the inner side and the outer side of the baffle plate via a rounded corner. Figure 2 As shown, the support plane is connected to the inner side surface and the outer side surface of the baffle plate through a fillet 50, wherein the radius of the fillet 50 is r, satisfying: r ≥ 0.2 mm.

[0045] More preferably, 0.3mm≤r≤1.5mm is satisfied. Since the thickness of the baffle is limited, if the radius of the fillet is r which is too large and greater than 1.5mm, it may occupy a larger space on the bottom wall of the baffle, resulting in insufficient area for setting the support plane, and the size of the support plane is difficult to reach the required size, causing the bottom coating to easily fall off. If the circumferential width of the baffle is increased, it will also affect the opening area of ​​the flow gap and affect the circulation crushing of the material; in addition, r is not less than 0.3mm, which can ensure that the fillet has sufficient curvature under the premise of limited thickness of the baffle, and prevent the risk of coating falling off due to connecting edges. Therefore, satisfying 0.3mm≤r≤1.5mm can not only avoid the falling off of the non-stick coating on the support plane, but also ensure the falling off of the non-stick coating at the connection between the side wall and the bottom wall of the baffle, so that the coating on the entire surface of the crushing cover can be firmly attached and the structure is reliable.

[0046] like Figure 2 As shown, in a preferred embodiment, the thickness of the bottom end of the baffle plate 31 at the support plane 33 is d1, and the thickness of the baffle plate at the crest position of the flow notch is d2, wherein d1>d2.

[0047] By adopting a non-uniform wall thickness along the circumferential direction of the baffle plate 31, which first increases and then decreases, under the rotating crushing of the crushing blade 25, the material enters and exits from the guide gap and moves disorderly along the surface of the baffle plate 31, so that the material is cyclically crushed and cut, thereby achieving a turbulent effect, increasing the probability of collision between the material and the crushing blade 25, and improving the fineness and uniformity of the crushing.

[0048] Preferably, the inner side surface of the baffle plate 31 is set as an inwardly protruding arc surface. When the material in the crushing cover 30 is rotated and cut by the crushing blade 25, the material will quickly rebound to the crushing blade 25 in different directions after colliding with the inner side surface of the baffle plate 31. The rebounded material is cut again, realizing cyclic crushing and improving the crushing efficiency. More preferably, the outer side surface of the baffle plate 31 is set as an outwardly protruding arc surface. The material flowing out of the crushing cover 30 through the flow gap 32 will move along the outwardly protruding arc surface under the rotating stirring action of the liquid flow, and will collide with the side wall of the cup body 10 and rebound during the movement. The rebounded material is crushed again in the crushing cover 30. Therefore, the material outside the crushing cover 30 can quickly enter the crushing cover 30 again for cutting, accelerating the crushing process and improving the crushing efficiency and crushing effect.

[0049] In a preferred embodiment, Figure 3 As shown, the baffle 31 includes a main body 301 and a thickened portion 302 connected to the lower end of the main body 301 and having a wall thickness increased relative to the main body 301, wherein the main body 301 and the thickened portion 302 are connected via a step surface, the average thickness of the main body 301 is d3, the average thickness of the thickened portion 302 is d4, d3<d4, and the support plane 33 is arranged on the bottom end surface of the thickened portion 302.

[0050] The baffle plate 31 includes a main body 301 and a thickened portion 302. Since the motor 24 is arranged inside the machine head 20, when the machine head 20 is supported on the work surface by the crushing cover 30, a "top-heavy" phenomenon will occur. Therefore, by setting the thickened portion 302 with increased wall thickness, the support stability of the machine head 20 can be improved from both the weight of the crushing cover 30 and the supporting area, and the machine head 20 can be prevented from tipping over. At the same time, the thickened portion 302 provides sufficient setting space for the supporting plane 33, thereby achieving a good adhesion effect of the non-stick coating, increasing the difficulty of deformation, and avoiding the non-stick coating from falling off.

[0051] In a preferred embodiment, Figure 4 As shown, the thickness of the baffle plate 31 gradually increases from the top to the bottom. The thickness at the top of the baffle plate 31 is d5, and the thickness at the bottom is d6, wherein d5<d6.

[0052] The thickness of the baffle plate 31 gradually increases from the top to the bottom, so that the non-stick coating can be firmly attached to the bottom support plane 33 of the baffle plate 31. On this basis, the thickness of the baffle plate 31 gradually increases, effectively avoiding the formation of angled surfaces on the surface of the baffle plate 31, reducing the risk of residue accumulation, and making it easier to clean thoroughly.

[0053] like Figure 4 , Figure 5 As shown, six baffles 31 are provided. Preferably, the support plane area S of a single baffle is ≤ 4 mm 2 , which can effectively avoid the overall thickness of the baffle being too thick or the horizontal extension distance of the baffle being too large along the circumferential direction, which will increase the probability of slurry residue adhering to the flow gap and the supporting surface, and prevent the inconvenience of cleaning. Moreover, if S is greater than 4mm 2 , and it may also cause the width of the baffle plate to be larger along the circumferential direction, affecting the opening area of ​​the flow gap, which is not conducive to the flow of materials. Therefore, it is necessary to meet S≤4mm 2 It can also achieve good circulation crushing of materials and improve crushing efficiency.

[0054] Six flow gaps are formed. The six baffles 31 can reliably gather the materials in the crushing cover 30 to achieve the effect of centralized crushing. At the same time, the multiple flow gaps 32 between the multiple baffles 31 can realize the cyclic crushing of the materials and improve the crushing efficiency.

[0055] Of course, the number of baffles 31 may be 4, 5, 7 or 8.

[0056] In a preferred embodiment, the contour of the flow gap 32 is arc-shaped and forms a wave crest at the upper end. The flow gap 32 includes a first flow gap 321 with a height H1 from the wave crest to the top wall of the crushing cover 30 and a second flow gap 322 with a height H2 from the wave crest to the top wall of the crushing cover 30. The first flow gap 321 and the second flow gap 322 are alternately arranged along the circumference of the crushing cover 30, and H1<H2.

[0057] By setting the upper end of the profile of the flow gap 32 to be arc-shaped and forming a wave crest, the flow direction of the material changes during the process of entering and exiting the flow gap 32, which has a disturbing effect, prevents the material from flowing out in a uniform direction, and increases the probability of collision between the material and the crushing blade 25. At the same time, the arc-shaped profile avoids the formation of a dead corner for slag hiding at the top of the flow gap 32, which facilitates the thorough cleaning of the crushing cover 30.

[0058] The height H1 from the wave crest of the first flow gap 321 to the top wall of the crushing cover 30 is less than the height H2 from the wave crest of the second flow gap 322 to the top wall of the crushing cover 30. The first flow gap 321 and the second flow gap 322 are arranged alternately, so as to form a wavy profile at the bottom of the crushing cover 30, and the height of the wave crest of the wavy profile is different, so that the liquid flow flowing out of different flow gaps 32 has a pressure difference, and the liquid flow between the outer side of the crushing cover 30 and the side wall of the cup body 10 rotates and flows, causing a turbulent effect, which promotes the mixing of liquid flows at different heights, and then effectively mixes the liquid outside the crushing cover 30, which is conducive to ensuring the consistency of the crushing rate, improving the circulation effect, and thus improving the crushing effect. The first flow gap 321 and the second flow gap 322 are arranged alternately, which is also conducive to the dynamic balance of the crushing blade 25 when whipping the liquid flow, so that the machine head 20 will not shake or vibrate significantly during the whipping process of the crushing blade 25.
