The utility model provides a cutter unit 220.

In the embodiment of the present invention, please refer to fig. 3 to 6, the cutter assembly 220 includes a cutter shaft 221, an upper cutter set 222 and a lower cutter set 223; the upper blade set 222 includes a first mounting portion 2221 for the knife shaft 221 to penetrate through and an upper blade 2222 connected to the periphery of the first mounting portion 2221, the upper blade 2222 includes a first bending section 2222a connected to the first mounting portion 2221 and bent upward, an included angle between the first bending section 2222a and a horizontal plane is α, and α is greater than or equal to 6 ° and less than or equal to 30 °; the lower blade group 223 includes a second mounting portion 2231 and at least two lower blades 2232 connected to the second mounting portion 2231; the knife shaft 221 penetrates the second mounting portion 2231, and the lower blades 2232 are distributed at the periphery of the second mounting portion 2231 at intervals.

The cutter shaft 221 is inserted through the first mounting portion 2221 of the upper cutter group 222 and the second mounting portion 2231 of the lower cutter group 223, so that both the upper cutter group 222 and the lower cutter group 223 can rotate under the rotation of the cutter shaft 221. The first bending section 2222a of the upper blade 2222 is bent upward, and it can be understood that the upper blade 2222 can increase the stirring height for the food during the rotation, thereby increasing the stirring range; and the upper blade 2222 and the horizontal plane form an included angle, so that the stirring force of the upper blade 2222 on food can be improved, and a better stirring effect can be realized, it should be noted that, in the use process of the food processor with the cutter assembly 220 of the present application, the cutter shaft 221 is generally in a vertical state, and therefore, the included angle formed between the cutter shaft 221 and the horizontal plane when the cutter shaft 221 is vertically placed should be understood as the included angle formed between the upper blade 2222 and the horizontal plane. Further, the angle α between the first bending section 2222a and the horizontal plane is in the range of: alpha is more than or equal to 6 degrees and less than or equal to 30 degrees, and the angle of the included angle alpha is not too large, so that the turbulence intensity of the liquid when the upper blade 2222 is contacted with the liquid in the rotating process can be reduced, and the effect of reducing noise is realized. Further, the size of the noise that produces among the comprehensive consideration stirring dynamics and the stirring process, the utility model discloses the optional first section of bending 2222a is for with the scope of the contained angle alpha of horizontal plane among the technical scheme: alpha is more than or equal to 15 degrees and less than or equal to 25 degrees.

The utility model discloses lower knife tackle 223 can strengthen the stirring effect to food equally among the technical scheme, and upper knife tackle 222 rotates along with arbor 221 simultaneously with lower knife tackle 223 in rotatory in-process, realizes the effect of stirring food simultaneously. Specifically, in the upper blade set 222, at least two upper blades 2222 are connected to the periphery of the first mounting portion 2221 at intervals, and the larger the number of the upper blades 2222, the smaller the force applied to each upper blade 2222 during stirring, so as to increase the service life of each upper blade 2222. Further, in order to make the force applied to each blade uniform, the upper blades 2222 are connected to the periphery of the first mounting portion 2221 at regular intervals. However, the number of the upper blades 2222 may not be too large, and if the number of the upper blades 2222 is too large, the distance between two adjacent upper blades 2222 is reduced, and it is difficult to achieve sufficient stirring and mixing effects. The utility model discloses well upper blade 2222's number can be selected to 2 to 4. The second mounting portion 2231 of the lower blade set 222 is located below the first mounting portion 2221, although the lower blade 2232 of the lower blade set 223 functions in the same manner as the upper blade 2222 of the upper blade set 222. Wherein the lower blade 2232 of the lower blade group 223 can be in a straight state, and can also comprise a bending section; when the lower blade 2232 includes a bent segment, the bent segment can be bent upward or downward. The bent section of the lower blade 2232 may be optionally bent downward, if desired to increase the stirring range.

The utility model discloses technical scheme is connected with the first section of bending 2222a of upwards buckling through the first installation department 2221 periphery at last blade 2222 for arbor 221 is rotating the in-process, and the stirring height of going up blade 2222 obviously increases, thereby has improved the stirring effect to food. In addition, the range of the angle α between the first bending section 2222a and the horizontal plane is defined as follows: alpha is more than or equal to 6 degrees and less than or equal to 30 degrees, and the bending angle of the first bending section 2222a cannot be too large, so that the turbulence intensity of liquid cannot be too large in the process of stirring food by the upper blade 2222, and the noise generated in the stirring process can be reduced to a certain extent.

In order to further reduce the turbulence intensity of the upper blade 2222 during the stirring process, the upper blade 2222 further includes a second bending section 222b connected to an end of the first bending section 2222a away from the first mounting portion 2221, a tip of the second bending section 222b is higher than the first bending section 2222a, and an angle between the second bending section 222b and the horizontal plane is larger than an angle between the first bending section 2222a and the horizontal plane.

With the above arrangement, it can be understood that the second bending section 222b is bent again based on a part of the first bending section 2222a, so that the distance from the tail end of the second bending section 222b to the central axis of the cutter shaft 221 after the second bending of the upper blade 2222 of the same length is reduced, so that when the angular velocity of the cutter shaft 221 is constant, the linear velocity of the tail end of the upper blade 2222 is reduced, thereby reducing the degree of stirring the liquid during the rotation of the upper blade 2222, that is, reducing the turbulence intensity of the liquid, and reducing the noise during the stirring to some extent. In addition, with the above arrangement, the stirring height of the upper blade 2222 can be further increased, so that the stirring effect of the food can be further improved.

It can be understood that the larger the bending angle of the second bending section 222b, the more the liquid is agitated, so that it is possible to increase the turbulence intensity and the noise to some extent. As shown in fig. 4, in the present embodiment, the angle between the second bending section 222b and the horizontal plane is defined as β, and β is greater than or equal to 20 ° and less than or equal to 70 °.

By setting the range of the angle β of the second bending section 222b to the horizontal plane as: beta is more than or equal to 20 degrees and less than or equal to 70 degrees, so that the bending angle of the second bending section 222b is not too large or too small; the turbulence intensity of the liquid is controlled in a proper range, so that the stirring range can be expanded on one hand, and the stirring noise can be reduced on the other hand. Further, for better stirring effect, the angle β between the second bending section 222b and the horizontal plane may be selected as follows: beta is more than or equal to 40 degrees and less than or equal to 60 degrees.

Specifically, based on the fact that the total length of the upper blade 2222 is constant, and the lower blade 2232 extends radially along the knife axis 221 and forms an angle of 0 ° with the horizontal plane, when the upper blade 2222 has the first bending section 2222a and the second bending section 222b, and the angle β between the second bending section 222b and the horizontal plane is set within the above range, and it is only the first bending section 2222a relative to the upper blade 2222, the following table 1 can be found through experiments:

TABLE 1

As can be seen from the experimental data in the above table, when the upper blade 2222 only has the first bending section 2222a, the noise is approximately in a positive correlation with the included angle between the first bending section 2222a and the horizontal plane; in addition, when the upper blade 2222 has the first section of bending 2222a and the second section of bending 222b simultaneously, and the first section of bending 2222a is 20 with the horizontal angle, the second section of bending 222b is 50 with the horizontal angle when, the noise that the stirring produced is minimum, consequently the utility model discloses the optional 20 of the first section of bending 2222a of upper blade 2222 among the technical scheme, the optional 50 of the second section of bending 222 b.

of course, in other embodiments, the upper blade 2222 may further have a plurality of bending sections, and an included angle between the bending section far away from the first mounting portion 2221 and the horizontal plane may be set to 20 ° to 70 °, so that on one hand, food can be effectively whipped, and on the other hand, the effect of reducing noise can still be achieved. Alternatively, in other embodiments, the upper blade 2222 may be further provided in an arc shape, and an included angle between a tangent line at the end of the arc-shaped upper blade 2222 and a horizontal plane may be set to be 20 ° to 70 °.

As shown in fig. 5, the utility model discloses the setting of lower knife tackle 223 also has certain influence to the noise among the technical scheme, and lower blade 2232 can extend along the horizontal direction. Alternatively, the bottom blade 2232 has a downward bevel, defining the angle between the bottom blade 2232 and the horizontal plane as θ, with θ being greater than 0 and less than 10. Setting the angle θ of the lower blade 2232 to the horizontal plane in the above range makes the lower blade 2232 less noisy when stirring the food. Further, in order to reduce the noise generated when the lower blade set 223 stirs the liquid, as shown in table 2, when the upper blades 2222 have the same structure, the angle between the lower blades 2232 of the lower blade set 223 and the horizontal plane is equal to the influence of the noise.

TABLE 2

As can be seen from table 2, the greater the angle of the lower blade 2232 to the horizontal, the more noisy. This is because the inclined lower blade 2232 forms an inclined stirring surface, so that the liquid generates a turbulent flow phenomenon, and as the angle between the lower blade 2232 and the horizontal plane increases, the greater the degree of the inclination, the greater the intensity of the turbulent flow, and the greater the noise generated. Therefore, in the technical solution of the present invention, the lower blade 2232 can be set to be 0 ° with the angle of the horizontal plane under the condition that the stirring effect of the lower blade 2232 on the food is not so much, so as to reduce the noise to the utmost.

In the technical solution of the present invention, as shown in fig. 6, the diameter of the circumference formed by the upper knife group 222 in the rotation process is d1, the diameter of the circumference formed by the lower knife group 223 in the rotation process is d2, and 0 is not less than d1-d2 is not less than 8 mm.

When d1-d2 is larger than 8mm, the difference between d1 and d2 is larger, so that the length of the upper blade 2222 is longer, the length of the lower blade 2232 is smaller, and on one hand, no good stirring effect is achieved at the part far away from the cutter shaft 221, and on the other hand, the linear velocity of the tail tip of the upper blade 2222 is larger, so that the noise is increased. When d1-d2 < 0, the stirring effect above the corresponding tail end of the lower blade 2232 is poor. Therefore, d1-d2 are not less than 0mm and not more than 8mm, so that the stirring effect can be improved and the noise can be reduced as much as possible in the process of matching and stirring the upper knife group 222 and the lower knife group 223.

Further, the length of the projection of the second bending section 222b on the horizontal plane is defined as L, and L is greater than or equal to 6mm and less than or equal to 10 mm.

It can be understood that if the angle and length of the first bending section 2222a are fixed and the projected length L of the second bending section 222b in the horizontal plane is greater than 10mm, the linear velocity of the tail end of the upper blade 2222 is greater, thereby increasing the noise generated during the stirring of the upper blade 2222. If the total length of the upper blade 2222 is kept constant and the angle of the first bending section 2222a is kept constant, the larger the projection length L of the second bending section 222b on the horizontal plane is, the smaller the length of the first bending section 2222a is, the negligible amount of the first bending section 2222a of the upper blade 2222 is, so that the upper blade 2222 has an approximately single-break-angle structure, and the noise generated by the upper blade 2222 during the stirring process is still increased. If the projection length L of the second bending portion 222b in the horizontal plane is less than 6mm, the upper blade 2222 may have an approximately single-folding-angle structure, which may increase the noise generated by the upper blade 2222 during the stirring process. Therefore, the utility model discloses well 6mm be less than or equal to L be less than or equal to 10mm, can make the noise that upper blade 2222 produced at the stirring in-process less.

As shown in fig. 7, when the strength of the upper blade 2222 and/or the lower blade 2232 is sufficient, the upper blade 2222 and/or the lower blade 2232 may further include a sound-deadening hole 2201 for reducing noise.

the upper blade 2222 and/or the lower blade 2232 are provided with the muffling hole 2201, so that when the cutter shaft 221 drives the blades to rotate at a high speed, the vibration frequency generated after the blades collide with food can be reduced, and the noise generated during stirring is reduced.

It can be understood that, in the present invention, the cutting edge of the upper blade 2222 and/or the cutting edge of the lower blade 2232 is linear or zigzag.

Further, the edge of the upper blade 2222 and/or the edge of the lower blade 2232 is serrated. It can be understood that when the cutting edge of the cutting edge is in a sawtooth shape, on one hand, the stirring efficiency can be improved; on the other hand, the saw-tooth-shaped cutting edge can effectively reduce the turbulent kinetic energy of the liquid, and further can reduce turbulent noise.

the utility model discloses still provide a stirring cup subassembly 20, as shown in FIG. 2, this stirring cup subassembly 20 includes cup 210 and cutter unit 220, and the concrete structure of this cutter unit 220 refers to above-mentioned embodiment, because this stirring cup subassembly 20 has adopted all technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and it is here no longer repeated one by one. Wherein the cutter assembly 220 is mounted within the cup 210.

When the cutter assembly 220 is mounted in the cup body 210, the cutter assembly can be optionally mounted at the bottom of the cup body 210, so that the gravity center of the cutter assembly 220 is lowered, the stability of the cutter assembly 220 in the working process is enhanced, and the noise is reduced. In addition, in order to further reduce noise, the cup 210 of the present invention may adopt a double-layer or multi-layer cup 210, i.e. the side wall and/or the bottom wall of the cup 210 is a double-layer hollow structure.
