Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a food processor. BACKGROUND

[0002] The existing food processor usually utilizes a cutter to crush food materials, such as the cutter assembly and food processor disclosed by the prior art, which comprises a support seat, a rotating shaft rotatably installed on the support seat, a driven magnetic disc fixedly connected with one end of the rotating shaft extending out of the support seat, and a shell in a cylindrical shape with one end closed and the other end open, wherein the support seat closes the shell to form a sealed cavity, the driven magnetic disc is located in the sealed cavity, and the support seat is connected with the shell. The driven magnetic disc comprises a bracket and a magnetic member installed on the bracket in the circumferential direction of the bracket, the magnetic member in the driving disc is a permanent magnet, a motor capable of rotating in a forward direction and a reverse direction is arranged in the base, and the driving disc is arranged at the end of the output shaft of the motor. The cutter assembly can be taken out from the stirring cup assembly as a whole, so that the cutter is more convenient to clean and replace.

[0003] During the operation of the cutter assembly, the material in the stirring cup is thrown outward under the centrifugal force of the cutter blade, and in the prior art, when the outer diameter of the support seat is small, a material blocking area is formed between the support seat and the side wall of the stirring cup below the cutter blade. The material blocking area can block the material, which directly lifts the cutter blade upward, lifts the support seat, causes transmission failure, and causes the whole machine to be abnormal. In addition, even if the outer diameter of the support seat is large, a material blocking area that is easy to block the material is formed between the edge of the support seat, the tip of the cutter blade and the inner wall of the stirring cup. Therefore, especially at the beginning of processing, the material particles in the stirring cup are large, and the large-particle material (bean material, jujube, cashew nut) is blocked in the material blocking area. On the one hand, the circulation of the material is affected, the material crushing uniformity is poor, and on the other hand, if the material hardness is large, such as unsoaked bean material, since the support seat and the bottom wall of the stirring cup are detachably connected without a reliable fixing structure, the large-hardness material can tilt the support seat upward through the tip of the cutter blade, so that the driven magnetic disc is tilted, and with the tilting of the support seat and the driven magnetic disc, the material flows into the side and below of the support seat. This part of the material further increases the tilting degree of the support seat, causes the driven magnetic disc to move away from the driving magnetic disc until the driven magnetic disc is out of the driving range, causes transmission failure, and causes the whole machine to be abnormal. SUMMARY

[0004] The utility model provides a kind of food processor, based on cutter assembly can be detached from stirring cup and be driven by driving magnetic disc in midair, on the basis of realizing flexible disassembly and cleaning of cutter assembly, solve the problem that cutter assembly is lifted by material to cause transmission failure in the processing process of prior art.

[0005] The utility model adopts the technical scheme that

[0006] The utility model provides a kind of food processing machine, including host computer, stir cup installed on host computer, knife assembly detachably installed in stir cup, the knife assembly includes tool holder, rotatably installed in the transmission disk of tool holder, stirring knife located above tool holder, transmission shaft passing through tool holder to connect transmission disk with stirring knife, the host computer is provided with motor and by motor driven drive disk, the drive disk drives the transmission disk rotation in midair, the bottom of the stir cup is equipped with the downwardly recessed sink, the tool holder has the matching portion that is inserted into the sink and is radially limited with the sink, the maximum rotating outer diameter of the stirring knife is less than the equivalent outer diameter of the matching portion, and the diagonal length of the longitudinal section of the matching portion is greater than the inner diameter of the sink.

[0007] The utility model provides a kind of food processing machine, by setting downwardly recessed sink in the bottom of stir cup, tool holder sets up the matching portion that is inserted into sink and is radially limited with sink, since the maximum rotating outer diameter of the stirring knife is less than the equivalent outer diameter of the matching portion, matching portion can have enough outer diameter to have the effect of nearly filling sink, therefore, matching portion can support the material below stirring knife, to avoid material directly contacting sink bottom or the bottom wall of stir cup, it is favorable to reduce the crushing interval below stirring knife, realize effective crushing, improve crushing effect, simultaneously, even if material is stuck in the below stirring knife and will be lifted up, since material has opposite direction, that is downward force to the matching portion of tool holder, both are mutually offset, so that knife assembly whole will not be lifted up due to the material below stirring knife, effectively avoid transmission disk to exceed the driving range of drive disk, therefore, improve transmission reliability, improve the working stability of knife assembly.In addition, the diagonal length of the longitudinal section of the matching portion is greater than the inner diameter of the sink, so when there is material on the tip of stirring knife and the stirring knife is tilted and lifted up, the whole knife assembly will have the tendency to turn over upwards to make the matching portion separate from the sink: specifically, the whole knife assembly turns over upwards with the position of tool holder top end supporting material as fulcrum.In this case, since the diagonal length of the longitudinal section of the matching portion is greater than the inner diameter of the sink, that is, the length of the line connecting the fulcrum of the matching portion and the opposite diagonal point is greater than the inner diameter of the sink, when the matching portion is lifted up by food and has the tendency to turn over outwards to separate from the sink, the diagonal point position of the matching portion will abut against the groove side wall of the sink, thereby limiting the whole matching portion from separating out of the sink, limiting the matching portion in the sink, limiting the inclination angle of tool holder, and the diagonal point abuts against the sink to avoid food from flowing into the below tool holder and the side of tool holder, therefore, even if tool holder is slightly tilted, but tool holder will be limited in sink due to the cooperation of matching portion and sink, will not separate from sink, limit transmission disk in the range that can be driven, effectively avoid transmission disk to exceed the driving range of drive disk, therefore, transmission is reliable, and the operation of knife assembly is stable.

[0008] In addition, the knife assembly comprises a knife seat, a transmission disc rotatably installed in the knife seat, a stirring knife located above the knife seat, a transmission shaft passing through the knife seat to connect the transmission disc and the stirring knife, the knife seat is used for wrapping the transmission disc, the reliability and service life of the transmission disc are improved, and the driving disc drives the transmission disc to reliably rotate in the air. Correspondingly, the driving disc can be exposed on the top of the main machine and close to the bottom of the stirring cup to be close to the transmission disc; or the driving disc can also be completely wrapped in the inside of the main machine and driven in the air from the transmission disc, so that the outside of the main machine no longer has a rotatable functional component, and use is safer.

[0009] In a preferred embodiment, the upper surface of the knife seat extends downwardly and obliquely from the center to the edge, and the stirring knife comprises a blade extending downwardly and obliquely.

[0010] More preferably, the blade is parallel to the upper surface of the knife seat.

[0011] Since the tip of the stirring knife has a larger linear speed than the root when rotating, the crushing is more delicate and the crushing effect is good, therefore, the upper surface of the knife seat extends upwardly and obliquely from the center to the edge, so that the material fully contacts the tip of the stirring knife, the effect of crushing delicacy is improved, and meanwhile, the stirring knife comprises a blade extending downwardly and obliquely, therefore, the blade and the upper surface of the knife seat have the same oblique trend, the distance between the knife seat and the blade is prevented from being too large due to the oblique knife seat, the problem of material being blocked below the blade and the problem of the knife seat being lifted up due to too much material being blocked at the tip of the blade are avoided, and the crushing uniformity and transmission reliability are improved.

[0012] The blade is parallel to the upper surface of the knife seat, so that the distance between the knife seat and the blade is uniform, the problem of large-particle material being blocked is avoided, and the crushing uniformity and transmission reliability are further improved.

[0013] In a preferred embodiment, the knife seat further comprises an extension located above the fitting portion, and the edge of the extension protrudes radially outward relative to the fitting portion to form a limiting flange.

[0014] By arranging the extension and the limiting flange, the limiting flange further reduces the distance between the knife seat and the side wall of the stirring cup, therefore, when the knife seat is tilted and lifted up, the limiting flange will first contact the side wall of the stirring cup to form a righting effect on the knife seat, so that the limiting portion is prevented from being separated from the sink groove, and the transmission is reliable.

[0015] In a preferred embodiment, a lower suction magnet is installed on the outer bottom wall of the stirring cup, an upper suction magnet is installed in the fitting portion, and the upper suction magnet and the lower suction magnet are attracted after the knife seat is installed in place.

[0016] By setting the upper suction magnet and the lower suction magnet, the knife assembly can be sucked on the bottom wall of the stirring cup, and the knife assembly will not automatically separate from the bottom wall of the stirring cup during pouring, improving the safety of user use; When installing the stirring knife assembly, the suction force between the upper suction magnet and the lower suction magnet assists the user to install the knife assembly in place, saving labor; When the stirring knife assembly needs to be taken out, the user only needs to manually overcome the suction force of the upper suction magnet and the lower suction magnet, which does not affect the flexible disassembly of the stirring knife assembly.

[0017] In a preferred embodiment, the top end of the groove side wall of the sink is connected with a flow guide wall gradually extending outward from bottom to top, and the stirring knife is at least partially located on the radial inner side of the flow guide wall.

[0018] By setting the flow guide wall gradually extending outward from bottom to top, the stirring knife is at least partially located on the radial inner side of the flow guide wall, so that the flow guide wall gathers the material downward to the middle, increases the contact probability of the material and the stirring knife, and improves the crushing efficiency; The distance between the flow guide wall and the tip of the stirring knife gradually increases from bottom to top, so that the large particle material can be gradually cut and crushed by the stirring knife during the sinking process, and becomes small, thereby reducing the situation that the material is stuck above the knife seat.

[0019] In a preferred embodiment, the top end of the groove side wall of the sink is connected with a horizontal transition wall extending outward.

[0020] By connecting the top end of the groove side wall of the sink with a horizontal transition wall extending outward, an expansion chamber can be formed above the transition wall, increasing the crushing volume of the stirring cup; In addition, the transition wall extends outward, expands the lateral gap between the tip of the stirring knife and the stirring cup, reduces the probability of material jamming, and reduces the probability of the knife assembly being lifted.

[0021] In a preferred embodiment, the stirring cup includes a cup body with an open lower end and a heating disc enclosed at the lower end of the cup body, and the sink is arranged at the bottom of the heating disc.

[0022] By arranging the sink at the bottom of the heating disc, the overall processing and manufacturing of the stirring cup is simple, the cup body is low in mold manufacturing cost, and the production and manufacturing are convenient.

[0023] In a preferred embodiment, the stirring cup includes a cup body with a bottom wall, the side wall of the cup body has a main body section and a contraction section located below the main body section and having a reduced inner diameter relative to the main body section, and the contraction section and the bottom wall of the cup body form the sink.

[0024] The stirring cup includes a cup body with a bottom wall, and the sink is formed by the contraction section and the bottom wall of the cup body. The contraction section also facilitates the mold release of the stirring cup, which is convenient for processing. In addition, the stirring cup itself has a bottom wall, which has strong sealing performance and eliminates the trouble of split assembly.

[0025] In a preferred embodiment, the stirring blade includes an upper blade and a lower blade connected to a drive shaft. The lower blade is connected to the drive shaft at a position lower than the upper blade, and the maximum rotational outer diameter of the lower blade is greater than the maximum rotational outer diameter of the upper blade.

[0026] By setting the stirring blade to have an upper blade and a lower blade, with the lower blade connected to the drive shaft at a position lower than the upper blade, the vertical crushing space of the stirring blade is expanded, thus improving the crushing efficiency. The maximum rotational outer diameter of the lower blade is greater than that of the upper blade, reducing the distance between the lower blade and the side wall of the stirring cup and preventing large particles from sinking and getting stuck.

[0042] It is explained that the utility model discloses the knife seat is cylindrical, and the longitudinal section of the matching portion 311 refers to the longitudinal section through the matching portion axis. Figure 4

[0043] The utility model provides a food processor, through setting down concave sunken groove 201 of the bottom of stirring cup 20, the knife seat 31 sets up the matching portion 311 of insertion into sunken groove 201 and with sunken groove 201 radial limit, because the maximum rotating outer diameter L1 of stirring blade 33 is less than the equivalent outer diameter L2 of matching portion 311, the matching portion 311 can have enough outer diameter to have the effect of nearly filling sunken groove 201, therefore, the matching portion 311 can support the material below stirring blade 33, and avoid the direct contact of material 40 to the groove bottom of sunken groove 201 or the bottom wall of stirring cup 20, is favorable to reduce the crushing interval below stirring blade 33, realizes effective crushing, promotes the crushing effect. Figure 4 As shown in the figure, even if the material 40 is stuck below the stirring blade 33 and will lift the stirring blade 33 upward, the stirring blade 33 is subjected to the upward force F1, because the material simultaneously has the force F2 in the opposite direction, that is, the downward force on the matching portion 311 of the knife seat 31, the two offset each other, so that the whole knife assembly 30 will not be lifted due to the material below the stirring blade 33, effectively avoiding the drive disk 32 from exceeding the driving range of the drive disk 12, therefore, improving the transmission reliability and the working stability of the knife assembly 30.

[0044] Because the diagonal length of the longitudinal section of the matching portion 311 is greater than the inner diameter of the sunken groove 201, when the material 40 at the tip of the stirring blade 33 tilts the stirring blade 33 upward, as shown in the figure, Figure 6 ​As shown, the knife assembly 30 as a whole has a tendency to flip upward to disengage the fitting portion 311 from the sink groove 201: specifically, the knife assembly 30 as a whole is flipped upward with the top end of the knife seat 31 as the fulcrum A. In this case, since the diagonal length of the longitudinal section of the fitting portion 311 is greater than the inner diameter of the sink groove 201, that is, the length of the line connecting the fulcrum A of the fitting portion 311 and the opposite diagonal point B is greater than the inner diameter of the sink groove 201, when the fitting portion 311 is lifted by the food and has a tendency to flip outward to disengage from the sink groove 201, the diagonal point B of the fitting portion 311 will abut against the groove side wall of the sink groove 201, thereby limiting the disengagement of the fitting portion 311 as a whole from the sink groove 201, limiting the fitting portion 311 within the sink groove 201, limiting the inclination angle of the knife seat 31, and avoiding the food from flowing into the lower and side of the knife seat 31 by the abutment of the diagonal point B and the sink groove 201, effectively avoiding the transmission disk 32 from exceeding the driving range of the driving disk 12, even if the knife seat is slightly inclined, the knife seat will be limited within the sink groove due to the cooperation of the fitting portion and the sink groove, and will not disengage from the sink groove, and the transmission disk will be limited within the drivable range, effectively avoiding the transmission disk from exceeding the driving range of the driving disk, thus, the transmission is reliable, and the operation of the knife assembly is stable.

[0045] In addition, the knife assembly 30 comprises the knife seat 31, the transmission disk 32 rotatably installed in the knife seat 31, the stirring knife 33 located above the knife seat 31, the transmission shaft 34 penetrating through the knife seat 31 to connect the transmission disk 32 and the stirring knife 33, the knife seat 31 wraps the transmission disk 32 for protection, improving the reliability and service life of the transmission disk 32, and enabling the driving disk 12 to reliably drive the transmission disk 32 to rotate.

[0046] In a preferred embodiment, referring to Figure 2 , the upper surface of the knife seat 31 is inclined downward from the center to the edge, and the stirring knife 33 comprises a blade 331 inclined downward.

[0047] Since the tip of the stirring knife 33 has a greater linear speed than the root when rotating, the crushing is finer and the crushing effect is good, therefore, the upper surface of the knife seat 31 is inclined upward from the center to the edge, so that the material fully contacts the tip of the stirring knife 33, improving the effect of fine crushing. At the same time, the stirring knife 33 comprises a blade 331 inclined downward, therefore, the blade 331 and the upper surface of the knife seat 31 have the same inclination trend, avoiding the problem of material jamming below the blade 331 and the tip of the blade 331 due to the distance between the knife seat 31 and the blade 331 becoming too large, and the knife seat 31 being lifted due to the large material jamming at the tip of the blade 331, improving the uniformity of crushing and the reliability of transmission.

[0048] The blade 331 is parallel to the upper surface of the tool seat 31, so that the distance between the tool seat 31 and the blade 331 is uniform, the problem of large particle material being stuck is avoided, and the crushing uniformity and transmission reliability are further improved.

[0049] In a preferred embodiment, referring to Figure 2 The tool seat 31 further comprises an extension 312 above the fitting part 311, and the edge of the extension 312 protrudes radially outward relative to the fitting part 311 to form a limiting flange 313.

[0050] By arranging the extension 312 and the limiting flange 313, the limiting flange 313 further reduces the distance between the tool seat 31 and the side wall of the stirring cup 20, so that when the tool seat 31 is tilted and lifted, the limiting flange 313 will first contact the side wall of the stirring cup 20 to form a righting effect on the tool seat 31, and under the combined limiting of the limiting flange 313, the fulcrum and the diagonal point, the limiting part is prevented from being separated from the sink groove 201, and reliable transmission is achieved.

[0053] In a preferred embodiment, as Figure 5 shown, the sink groove 201 is connected with a flow guide wall 202 extending outward from bottom to top, and the stirring knife 33 is at least partially located on the radial inner side of the flow guide wall 202.

[0054] By arranging the flow guide wall 202 extending outward from bottom to top, the stirring knife 33 is at least partially located on the radial inner side of the flow guide wall 202, so that the flow guide wall 202 gathers the material downward to the middle, increases the contact probability of the material and the stirring knife 33, and improves the crushing efficiency; the distance between the flow guide wall 202 and the tip of the stirring knife 33 gradually increases from bottom to top, so that the large particle material can be gradually cut and crushed by the stirring knife 33 during the sinking process, and becomes small, thereby reducing the situation that the material is stuck above the tool seat 31.

[0055] Of course, the utility model is not limited to connecting the flow guide wall at the top end of the sink groove, and in fact, in another preferred embodiment, the top end of the sink groove 201 is connected with a transition wall extending horizontally outward.

[0056] By connecting the top end of the tank side wall of the sink 201 with the horizontally outward extending transition wall, the expansion cavity can be formed above the transition wall, the crushing volume of the stirring cup 20 is increased, in addition, the transition wall extends outward, the lateral gap between the tip of the stirring blade 33 and the stirring cup 20 is expanded, the probability of material jamming is reduced, and the probability of the knife assembly 30 being lifted is reduced.

[0057] In addition, it should be noted that the forming mode of the sink is not limited in the utility model, for example Figures 1-6 In the embodiment shown, in combination with Figure 5 , 6 The stirring cup 20 includes the cup body 21 provided with an open lower end and the heating disc 22 closed at the lower end of the cup body, and the sink 201 is arranged at the bottom of the heating disc 22.

[0058] By arranging the sink 201 at the bottom of the heating disc, the overall processing and manufacturing of the stirring cup 20 are simple, the die forming cost is low, and the production and manufacturing are facilitated.

[0059] It can be understood that in the embodiment, the side wall of the heating disc can also form the flow guide wall or the transition wall.

[0064] By setting the stirring blade 33 to have the upper blade 332 and the lower blade 333, the connecting position of the lower blade 333 with the transmission shaft 34 is lower than that of the upper blade 332, thus, the crushing space of the stirring blade 33 along the vertical direction is enlarged, the crushing efficiency is improved, the maximum rotating outer diameter of the lower blade 333 is greater than that of the upper blade 332, the distance between the lower blade 333 and the side wall of the stirring cup 20 is reduced, and the sinking and jamming of the large-particle material are avoided.
