The motor drives the stirring knife assembly to rotate in a first direction in the stirring bowl so that the knife edge rubs food materials, and the motor drives the stirring knife assembly to rotate in a second direction opposite to the first direction in the stirring bowl so that the knife back stirs the minced food materials.

As set forth above, since the stirring blade assembly includes the blade and the back. The back of a knife is smoothly connected with the blade body, and the motor drive stirring knife assembly is in the stirring bowl and rotates towards a first direction, so that food is minced by the cutting edge, the motor drive stirring knife assembly is in the stirring bowl and rotates towards a second direction opposite to the first direction, so that the back of a knife stirs the minced food, compared with a food processor needing to be replaced by the stirring knife assembly and the stirring piece, the function of mincing and stirring can be realized only by rotating the stirring knife assembly towards different directions, parts do not need to be replaced (after the stirring knife assembly is minced, the stirring knife assembly is replaced by the stirring piece for stirring), the operation of the food processor is not complicated, only one part of the stirring knife assembly needs to be cleaned, and the number of cleaned parts is small.

In some embodiments, the blade body includes a body upper surface and a body lower surface, and the back includes an arcuate surface, the arcuate surface being smoothly connected to at least the body upper surface in the body upper surface and the body lower surface.

As the arc-shaped surface is at least in smooth connection with the upper surface of the body, the minced food can move along the upper surface of the body along the arc-shaped surface in the process of stirring the minced food, so that the food is stirred, the physical form of the food is not changed, the food is not minced, and a better stirring effect is achieved.

In some embodiments, the maximum vertical height of the arc-shaped surface and the upper surface of the body is h, and h is more than or equal to 1mm and less than or equal to 3mm.

As the thickness of the back of the knife is ensured to play a role in stirring because the h is more than or equal to 1mm and less than or equal to 3mm, and therefore, the minced food is not easy to be minced again in the stirring process.

In some embodiments, the body lower surface is parallel to a horizontal plane, and the back includes a vertical surface that is smoothly connected to the arcuate surface and perpendicular to the body lower surface.

As the vertical surface is smoothly connected with the arc surface and is vertical to the lower surface of the body, no part for mincing food materials is formed, the minced food materials are pushed to move towards the arc surface, further, the minced food materials move towards the upper surface of the body under the action of the arc surface, and the stirring effect of the stirring cutter assembly is good.

In some embodiments, the vertical surface has a width n,0.5 mm.ltoreq.n.ltoreq.1 mm.

As the setting is that n is less than or equal to 0.5mm and less than or equal to 1mm, the stirring blade assembly is more beneficial to pushing food to move towards the arc-shaped surface, and therefore the stirring effect of the stirring blade assembly is good.

In some embodiments, the arc surface is tangentially connected with the upper surface of the body to realize the smooth connection, and the distance between the tangential point of the upper surface of the body and the arc surface and the vertical surface along the horizontal direction is d, and d is more than or equal to 0.5mm and less than or equal to 2mm on the longitudinal section of the stirring cutter assembly.

As the d is more than or equal to 0.5mm and less than or equal to 2mm, the arc-shaped surface of the knife back is ensured to have enough width, so that the knife back is less likely to further grind the minced food, and a better stirring effect is achieved.

In some embodiments, the blade comprises a blade face intersecting a lower body surface of the blade body to form a cutting edge, the blade face being inclined upwardly relative to the horizontal, the blade face being inclined at an angle a; the blade body comprises a body upper surface which is smoothly connected with the blade back, and the body upper surface is also connected with the blade surface; the upper surface of the body is inclined upwards relative to the horizontal plane, and the inclination angle of the upper surface of the body is b, and a is more than b.

As a & gtb, the speed of the food moving towards the knife back can be slowed down by taking the moving direction of the food as a reference in the process of mincing the food, the food is beneficial to staying at the knife edge for a long time and being minced, the mincing effect is good, the food moves towards the knife edge surface through the upper surface of the body in the process of stirring the food, at the moment, the food falls from the knife edge surface more easily by looking at the moving direction of the food, thereby avoiding the risk that the minced food is minced again by the knife back.

In some embodiments, 5.ltoreq.b.ltoreq.20 degrees.

As the angle b is equal to or less than 5 degrees and equal to or less than 20 degrees, the mincing effect is good because the food material stays at the blade for a longer time in the mincing process, and the food material falls off from the blade surface more easily in the stirring process, so that the accumulation of the food material at the back of the knife is avoided, and the risk that the minced food material is minced again by the back of the knife is avoided.

In some embodiments, 20 degrees.ltoreq.a.ltoreq.45 degrees.

As the angle a is smaller than or equal to 20 degrees and smaller than or equal to 45 degrees, the mincing effect is good because the food material stays at the blade for a longer time in the mincing process, and the food material falls off from the blade surface more easily in the stirring process, so that the accumulation of the food material at the back of the knife is avoided, and the risk that the minced food material is minced again by the back of the knife is avoided.

In some embodiments, the cutter blades have four blades, and two S-shaped cutters which are staggered with each other are formed in the circumferential direction of the cutter shaft.

As the cutter blades form two S-shaped cutters which are staggered with each other in the circumferential direction of the cutter shaft, the stirring cutter assembly has a simple structure under the condition of realizing the mincing function and the stirring function.

In some embodiments, the motor rotates in the first direction at a speed of 2000 rpm to 3000 rpm and/or the motor rotates in the second direction at a speed of 800 rpm to 2000 rpm.

As set forth above, since the rotation speed of the motor in the first direction is 2000 rpm to 3000 rpm, and/or the rotation speed of the motor in the second direction is 800 rpm to 2000 rpm, the motor drives the stirring blade assembly to rotate in the first direction to better cut up the food material, and when the stirring blade assembly rotates in the second direction to stir the food material, the minced food material can be better stirred, and the food material cannot be minced again (or twisted more).

Referring to fig. 3 in combination with fig. 1 and fig. 2, embodiments of the present application disclose a food processor. The food processor includes a stirring blade assembly 10, a stirring bowl 20, and a motor 30. The motor 30 drives the mixing blade assembly 10 either forward or reverse within the mixing bowl 20. Of course, the food processor illustrated in the present application further includes a bowl cover 40, a control board 50 and a housing 60, and of course, the parts included in the food processor may be different according to the product types. In the embodiment of the present application, the motor 30 drives the stirring blade assembly 10 to rotate forward to achieve the mincing function, and drives the stirring blade assembly 10 to rotate reversely to achieve the stirring function. Of course, in other embodiments, this is not limiting. The motor 30 may be a direct current motor. The functions of all the components of the food processor are as follows: the mixing bowl 20 is used for containing food materials; the cutter blades 2 are used for processing, cutting and stirring food materials; the bowl cover 40 is used for preventing food material from overflowing and fixing a machine head (the machine head comprises a motor 30 and a shell 60); a motor 30 (such as a DC motor) for driving the blender blade assembly 10 in rotational motion; the control board 50 is used for controlling the rotating speed, the forward rotation and the reverse rotation; the housing 60 is used for mounting the motor 30 and the control board 50. The structure of the blender blade assembly 10 is described in more detail below.

In addition, although fig. 1 and 2 illustrate a meat grinder as an example, and the motor 30 is located above the bowl cover 40, in some food processors, the motor is located below a stirring cup (a meat grinder bowl may be understood as a stirring cup), and the food processor may also use the technical solution described in the present application.

Referring to fig. 3 in combination with fig. 1 and 2, a blender blade assembly 10 is shown. The stirring blade assembly 10 comprises a cutter shaft 1 and blades 2 assembled on the cutter shaft 1. The number of blades 2 of the stirring blade assembly 10 is not limited to four as shown. Although the blender blade assembly 10 is illustrated in fig. 1 and 2 as an accessory for a meat grinder, in various embodiments of the present application, the blender blade assembly 10 is provided with both a grinding function (e.g., grinding meat into meat) and a blending function (e.g., blending meat to provide a more thorough mixing of meat with ingredients), and a food grinder having both of these functional requirements may use the blender blade assembly 10 of the present application.

Referring to fig. 3 in combination with fig. 4 and 5, the blade 2 includes a blade She Benti, and a blade edge 22 and a blade back 23 disposed on the blade She Benti. The knife back 23 is smoothly connected with the knife She Benti 21 for stirring food materials. Fig. 4 and 5 illustrate two smoothly connected structures, differing in: the connection between the back 23 and the body lower surface 212 of the blade She Benti 21 shown in fig. 4 is different from the connection between the back 23 and the body lower surface 212 in fig. 5, as will be described later. The smooth connection, such as an arcuate transition, enables the back 23 to agitate the food material (e.g., mix the meat) without mincing the food material like the blade 22, e.g., mincing the food material again.

As set forth above, since the blender blade assembly 10 includes the blade 22 and the back 23. The back 23 is smoothly connected with the knife She Benti, and the motor drives the stirring knife assembly to rotate in a first direction in the stirring bowl so that the knife edge 22 minces food, the motor drives the stirring knife assembly 10 to rotate in a second direction opposite to the first direction in the stirring bowl so that the back 23 stirs the minced food, more specifically, the stirring knife assembly 10 rotates in the first direction (forward rotation), the knife edge 22 minces food, the stirring knife assembly 10 rotates in the second direction (reverse rotation), the back 23 can stir the minced food, or the stirring knife assembly 10 rotates in the second direction (reverse rotation), the stirring knife assembly 10 rotates in the first direction (forward rotation), and the back 23 can stir the minced food. Compared with a food processor needing to replace and use a stirring blade assembly and a stirring piece, the function of mincing and stirring can be realized only by rotating the stirring blade assembly 10 in different directions, parts do not need to be replaced, the operation of the food processor is not complicated, only the part of the stirring blade assembly 10 is required to be cleaned, and the number of cleaned parts is small.

Referring to fig. 4 and 5, the blade body 21 includes a body upper surface 211 and a body lower surface 212. The back 23 includes an arcuate surface 231. The curved surface 231 is smoothly connected with at least the upper surface 211 of the body in the upper surface 211 of the body and the lower surface 212 of the body. In some embodiments, the arcuate surface 231 is at least tangential to the body upper surface 211 to achieve the smooth connection. The arcuate surfaces 231 are shown in fig. 4 as being tangential to the body upper surface 211 and joined at a tangent, and fig. 5 shows the arcuate surfaces 231 as being tangential to both the body upper surface 211 and the body lower surface 212. The body upper surface 211 and the body lower surface 212 are not limited to the plane as shown.

As set up above, because arcwall face 231 at least with body upper surface 211 smooth connection, at the in-process of stirring the food that is minced, can make the food that is minced follow arcwall face 231 moves to body upper surface 211 to by the stirring, can not change the physical form of food, can not minced the food more, play better stirring effect.

In some embodiments, referring to fig. 4 and 5, in the first blade 2 and the second blade 2, the arcuate surface 231 has a maximum vertical height h from the lower surface 212 of the body of 1 mm.ltoreq.h.ltoreq.3 mm, for example, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm, or 3mm. In the embodiment shown in fig. 4, the tangent point of the curved surface 231 and the upper surface 211 of the body is lower than the highest point of the curved surface 231, however, in some embodiments, for example, in the case that the arc length corresponding to the curved surface is 1/4 of the arc length, the tangent point may be just the highest point of the curved surface 231. This embodiment also has the advantages described later.

As the setting is that the h is less than or equal to 1mm and less than or equal to 3mm, the thickness of the knife back is ensured to play a role in stirring, so that the minced food materials are not easy to be minced again in the stirring process, and the method is generally applicable to the existing meat grinder with the motor power of 80-200w, and the cost is not increased additionally. It should be noted that in some embodiments, h may be greater than 3mm, where the power required to achieve agitation by the stirring blade may be increased, and a more powerful motor drive may be used.

Referring to fig. 4, the lower surface 212 of the body is parallel to the horizontal plane, and the back 23 includes a vertical surface 232, and the vertical surface 232 is smoothly connected to the curved surface 231 and is perpendicular to the lower surface 212 of the body.

As set up above, because vertical face 232 with arcwall face 231 smooth connection and vertical face 232 is perpendicular with body lower surface 212, do not form the position of mincing food, be favorable to promoting the food that is minced to arcwall face 231 motion, and then, make the food that is minced move to body upper surface 211 under the effect of arcwall face 231, stirring effect of stirring sword subassembly 10 is good.

With continued reference to fig. 4 and 5, the arcuate surface 231 is tangentially connected to the upper surface 211 of the body so as to achieve the smooth connection, and a distance d between a tangential point of the upper surface 211 of the body and the arcuate surface 231 and the vertical surface 232 in a horizontal direction is 0.5 mm.ltoreq.d.ltoreq.2 mm, for example, 0.5mm, 0.8mm, 1mm, 1.3mm, 1.5mm, 1.8mm or 2mm, etc. in a longitudinal section of the stirring blade assembly.

As the above arrangement is adopted, d is more than or equal to 0.5mm and less than or equal to 2mm, so that the arc-shaped surface 231 of the knife back 23 is ensured to have enough width, and therefore, the knife back 23 is less likely to further grind the minced food materials, and a better stirring effect is achieved.

Referring to FIG. 4, in some embodiments, the vertical surface 232 has a width n,0.5 mm.ltoreq.n.ltoreq.1 mm.

As the arrangement is that n is less than or equal to 0.5mm and less than or equal to 1mm, the vertical surface 232 is more beneficial to pushing the food material to move towards the arc surface, so that the stirring effect of the stirring blade assembly 10 is good.

Referring to fig. 4 and 5 in combination with fig. 3, the blade 22 includes a blade face 221, and the blade face 221 intersects the lower body surface 212 of the knife She Benti to form a cutting edge 222. The blade surface 221 is inclined upward with respect to the horizontal plane, and the angle of inclination of the blade surface 221 is a. The blade body 21 includes a body upper surface 211 smoothly connected to the back 23, and in this case, the back 23 is not limited to the structure shown in fig. 4 and 5, and it is sufficient to stir the minced food material. The body upper surface 211 is also connected to the blade face 221. The upper surface 211 of the body is inclined upwards relative to the horizontal plane, and the inclination angle of the upper surface 211 of the body is b, and a is larger than b.

As a & gtb, the speed of the food moving towards the knife back 23 is slowed down by taking the moving direction of the food as a reference in the process of mincing the food, the food stays at the knife edge 22 for a long time, the mincing effect is good, the food moves towards the knife edge surface 221 through the upper surface 211 of the body in the process of stirring the food, at the moment, the food falls from the knife edge surface 221 more easily when being seen in the moving direction of the food, thereby avoiding the risk that the minced food is piled up at the knife back 23 and is minced again by the knife back 23.

Based on the above effect of a > b, the skilled person will appreciate that the respective values of a and b may be determined according to the actual product.
