Description

  The present invention relates to a disposer that is installed under a kitchen sink or the like and pulverizes and discharges generated waste.

  This type of disposer includes a turntable (rotary plate) that receives garbage such as garbage thrown into the bottom of the crushing chamber, a fixed blade provided around the turntable, and a mounting pin on the upper surface of the turntable. A hammer mill type having a swing hammer (rotating blade) attached so as to be freely rotatable by the above is disclosed (for example, Patent Document 1). This disposer rotates the turntable that received the object at high speed with a motor, moves the object together with water to the fixed blade side by centrifugal force, and presses the object against the fixed blade while making contact with the swing hammer. Then, grind and crush the porridge.

Japanese Patent Laid-Open No. 2004-243241

In the above disposer, the swing hammer is mounted on the upper surface of the turntable so as to be rotatable about a rotation fulcrum located on the mounting pin, and a blade portion which is a hammer portion extending from the mounting portion to a position close to the fixed blade. The blade portion is formed with a single blade, and two swing hammers are arranged at symmetrical positions on the diagonal of the mounting pin.
The swing hammer is designed in advance so that the blade part has a heavier weight balance than the mounting part, and when the swing hammer is in a freely rotating state free from collisions with objects and water during high-speed rotation of the turntable, In response to the centrifugal force associated with the rotation of the table, the blade portion of each swing hammer opens to the outside on the side of the fixed blade, and a rotation state (the blade portion outside open state) that faces the fixed blade is obtained.

  In the initial stage of pulverization of the porridge, the porridge has a large diameter and is an aggregate of many solids and tends to be soft and easily pulverized. Assuming that the disposer is started with this large-diameter article placed on the turntable between the fixed blade and the blade, the large-diameter article is sandwiched between the fixed blade and the rotary blade. The swing hammer is in a rotational state (inclined state in the blade portion) in which the blade portion is separated from the fixed blade and inclined inward on the mounting pin side. At this time, the swing hammer presses the large-diameter object against the fixed blade in an attempt to rotate from the inwardly inclined state of the blade part to the open state of the blade part by centrifugal force acting on the swing hammer itself, and the large-diameter object pressed against the fixed blade. Things are crushed into smaller diameter porridges.

  On the other hand, in the final stage of crushing of the porridge, the porridge has a small diameter and is an aggregate of a small amount of solid matter, and tends to be hard and hard to crush including bones. Assuming that this small-diameter frame is in contact with the blade in an open state, the small-diameter frame is pressed against the fixed blade by the centrifugal force acting on the small-diameter frame itself. Receiving a reaction force to receive the force to maintain the blade open state, the small-diameter rod enters a slight gap between the blade and the fixed blade, and the fixed blade has a smaller diameter. It is crushed into a bowl.

  Here, when the small-diameter article pulverized in the final stage of pulverization is a hard small-diameter article that is not easily crushed by the fixed blade, the hard small-diameter article enters the gap between the blades and is about to be crushed. The reaction force due to the impact acts on the blade. When the reaction force is larger than the turning force that the swing hammer receives centrifugal force due to the turntable rotation and rotates from the blade inward tilted state to the blade outer open state, the swing hammer moves from the blade outer open state to the blade inner part. Rotates to a tilted state. When the swing hammer is rotated in the blade part, a relatively large gap between the blades is formed between the blade part and the fixed blade. There is a risk of the so-called reaction slip-through phenomenon of the object.

  The rigid small-diameter frame that has passed through the gap between the blades can be pulverized at the second swing hammer position arranged at the symmetrical position on the diagonal of the mounting pin by the rotation of the turntable. The hard small-diameter container that is not crushed even at the second swing hammer position makes a round in the pulverization chamber by the rotation of the turntable and returns to the original first swing hammer position. In the meantime, if the swing hammer returns to the initial open state of the blade part from the inclined state inside the blade part due to the centrifugal force acting on the blade part, the hard small-diameter frame can be crushed again. In this way, the swing hammer repeats the rotation state between the above-described blade outer open state and the blade inner tilt state until the hard small-diameter frame is crushed, and there is a possibility that the so-called rotation repetition phenomenon of the swing hammer may occur. .

  On the other hand, the hard hammer is not crushed even at the second swing hammer position, and the swing hammer is tilted in the blade part by the centrifugal force acting on the blade part while returning to the original first swing hammer position through the grinding chamber. If the blade is not completely restored from the initial state to the blade edge open state, the swing hammer remains tilted in the blade and passes through the gap between the blades without contacting the hard small-diameter article once. There is a risk that a so-called perfect slip-through phenomenon will occur.

  When the swing hammer rotation repetition phenomenon as described above, and the rebound slipping phenomenon and complete slipping phenomenon of the sword at the swing hammer position occur, the scabbard is not crushed at the first swing hammer position of the swing hammer and is turned by the turntable. Since crushing is attempted again after moving to the second swing hammer position or to the original first swing hammer position, time loss occurs in the crushing of the fried food, and the fried food cannot be crushed efficiently. There's a problem.

  The present invention has been made based on the above-mentioned circumstances, and the object of the present invention is to suppress the repeated swinging phenomenon of the swing hammer, the rebound slipping phenomenon and the complete slipping phenomenon of the sword at the swing hammer position, and any state. It is an object to provide a high-performance disposer that can reduce the time loss required for pulverization and enables efficient pulverization even for the above-mentioned porridge.

In order to achieve the above object, the disposer of the present invention is provided with a rotating plate that receives and rotates the porcelain charged at the bottom of the crushing chamber, a fixed blade provided around the rotating plate, and an upper surface of the rotating plate. A disposer having a rotary blade that is pivotably mounted, and the rotary blade is mounted on the upper surface of the rotary plate with a mounting portion that pivotally supports the rotary blade around a rotation fulcrum, and from the mounting portion to the fixed blade and a blade portion extending until the blade portions have a plurality of blades, rotating moment around pivot point of each blade is the same, the rotational moment is rotated from the position of the center of gravity of the blade weight and the blade It is the product of the length of the moment arm up to the fulcrum, and the blade part is the foremost blade located in the forefront in the rotational direction of the rotating plate, and one or more rear blades located behind the foremost blade in the rotational direction The front edge is lighter than the rear edge and the moment arm is It is characterized by decoction (claim 1).

Preferably, the rotary blade is opened to the outside on the fixed blade side of the rotary blade, the blade portion is in an open state where the rotary blade faces the fixed blade, and the blade portion is separated from the fixed blade on the rotation fulcrum side. The blade is rotated between an inwardly inclined state of the blade part, the foremost blade is in contact with the container with the protruding part protruding in the rotating direction in the inwardly inclined state of the blade, and the rear blade is in the open state of the blade part. contacting the kitchen garbage was a vertical portion which is perpendicular to the rotation direction (claim 2).

According to the present invention, the blade portion of the rotary blade has a plurality of blades, so that the porridge can be efficiently pulverized stepwise by one rotary blade .
The rotation moment about the pivot point of each blade by the same, it is possible to balance the rotational moment of each blade relative to the pivot point of the rotary blade. Accordingly, even when a plurality of blades are formed on the blade portion, it is possible to prevent the rotation of the rotary blade from being hindered by the weight imbalance of the rotary blade.

In addition, when a hard small-diameter object collides with the blade part, the blade part is opened to the outside on the fixed blade side, and the blade part is moved from a rotating state (blade part open state) in which the rotary blade is opposed to the fixed blade. Even if the rotary blade rotates in a rotational state (inclined state in the blade part) that is spaced apart from the fixed blade and inwardly inclined on the mounting pin side, the blade part is returned to the open state by the centrifugal force acting on the rotary blade. be able to. Therefore, high-performance disposer is achieved by reducing the crushing loss of the freight and performing the efficient crushing by suppressing the repetitive rotation phenomenon of the rotary blade, and the reaction and complete slipping of the fouling at the rotary blade position. Ru can provide.

Further, rotation moment, Ru Sekidea of the length of the moment arm from the center of gravity of the blade weight and the blade to the rotation supporting point.
Moreover, most prior blade by long lightweight and and moment arm of a rear edge, sandwiched large径厨garbage was moved to the rotary blade position in crushing the initial stage between the light and long forwardmost blade and the fixed blade Can be crushed. The large-diameter cake in the initial stage of pulverization is an aggregate of many solids and tends to be pulverized softly, so even if the foremost blade is lightweight, it can be efficiently pulverized by being sandwiched between fixed blades. is there.

On the other hand, the rear blade is a small-diameter rod crushed by the front blade, or a hard small-diameter rod that is still being pulverized at the final stage of pulverization between the rear blade and the fixed blade, which is heavier and shorter than the front blade. Can be ground and crushed. At the final stage of pulverization, small-diameter objects are aggregates of a small amount of solid matter and tend to be hard and difficult to pulverize, including bones, etc. Is possible. Therefore, by providing the front blade and the rear blade on the rotary blade, a large diameter container, a small diameter container, and a hard small diameter container can be selectively and efficiently crushed with one rotary blade. The grinding loss can be further reduced (Claim 1 ).

Further, according to the present invention, the foremost blade is pressed against the fixed blade based on the centrifugal force acting on the rod by contacting the rod with the protruding portion protruding in the rotation direction side in the blade portion inclining state. Further, the soot can be pulverized by the pressing force of the foremost blade based on the rotational force of the rotating plate and the frictional force caused by the contact of the soot with the fixed blade. Since the pressing force by the foremost blade acts in a direction completely different from the pressing force and frictional force on the fixed blade, particularly large-diameter articles can be efficiently crushed.

On the other hand, the rear blade comes into contact with the rod at a vertical portion that is perpendicular to the rotation direction in the blade-opened state, so that the pressing force to the fixed blade based on the centrifugal force acting on the rod and the rotating plate The porridge can be crushed by the pressing force by the rear blade based on the rotational force and the frictional force caused by the porridge contacting the fixed blade. Since the pressing force by the rear blade acts in the direction opposite to the pressing force to the fixed blade, it is possible to efficiently grind and pulverize small-diameter articles in particular. (Claim 2 ).

The disposer 1 is a hammer mill type which is installed on the lower side of a kitchen sink or the like and pulverizes the generated waste and discharges it together with water from a discharge pipe (not shown). The disposer 1 has a crushing chamber 4 formed inside a flange portion 2 to which an upper casing (not shown) is connected, and a turntable (such as garbage that is thrown in from the upper casing) is received at the bottom 4a of the crushing chamber 4 ( (Rotating plate) 6 is arranged.

  A rotation shaft of a motor (not shown) housed in a lower casing 8 disposed on the lower side of the turntable 6 is connected to the turntable 6 by bolts 12 on an upper surface 6 a of the turntable 6. Around the turntable 6, there is provided a fixed blade 14 formed in an intermittent groove shape in the circumferential direction of the inner wall 4b of the crushing chamber 4, and on the upper surface 6a of the turntable 6 on a diagonal line through bolts 12. Two swing hammers (rotating blades) 16 are rotatably attached by attachment pins 18.

  FIG. 2 is a top view showing the swing hammer 16 from above. The swing hammer 16 is attached to the upper surface 6 a of the turntable 6 with an attachment pin 18. The swing hammer 16 includes an attachment portion 22 that pivotally supports the swing hammer 16 around the pivot fulcrum P, and a blade portion 24 that extends from the attachment portion 22 to the vicinity of the fixed blade 14.

FIG. 3 shows an upper surface of the disposer 1 in which the blade portion 24 is opened to the outside on the side of the fixed blade 14 and the swing hammers 16 are turned to face the fixed blade 14 in a rotating state (blade portion open state). FIG. FIG. 3 shows a state in which the swing hammers 16 and 16 are in the same posture, and the same applies to FIGS. 4 to 8 described below.
When the turntable 6 rotates at a high speed in the counterclockwise rotation direction A by driving the motor, the bowl is moved to the fixed blade 14 side together with water by centrifugal force acting on itself.

  Each swing hammer 16, 16 is designed in advance so that the blade portion 24 has a heavier weight balance than the mounting portion 22, so that the swing hammer 16 is free from collisions of objects and water during high-speed rotation of the turntable 6. When the turning state is reached, the blade portion is opened as shown in FIG. 3 in response to the centrifugal force accompanying the turning of the turntable 6. Then, the porridge is pressed against the fixed blade 14 by centrifugal force acting on the porcelain itself, crushed and pulverized, and a recovery groove (not shown) formed in the gap between the turntable 6 and the fixed blade 14 is formed. It is discharged from the discharge pipe together with water.

  The blade portion 24 is a first blade (blade, foremost blade) 26 positioned in front of the turntable 6 in the rotational direction A, and a first blade 26 positioned behind the first blade 26 in the rotational direction A of the turntable 6. 2 blades (blade, rear blade) 28. Assuming that an imaginary line shown by a broken line in FIG. 2 is a boundary line of the blade part 24, the first blade 26 is closer to the rotation direction A side than the attachment part 22 in a top view when viewed in the blade part open state shown in FIG. The second blade 28 has a vertical portion 28a that is perpendicular to the rotation direction A when viewed from above, and has a rectangular shape that protrudes toward the fixed blade 14 side. Is formed.

  The first blade 26 and the second blade 28 have an inter-blade gap D, a blade height H (shown in FIG. 1), and a rotational moment M1 around the rotation fulcrum P when their end faces face the fixed blade 14. M2 is formed identically. As shown in FIG. 2, the rotational moment M1 is the product of the weight W1 of the first blade 26 and the length L1 of the moment arm indicated by the alternate long and short dash line from the center of gravity G1 of the first blade 26 to the rotation fulcrum P (W1). × L1)

On the other hand, the rotational moment M2 is a product (W2 × L2) of the weight W2 of the second blade 28 and the length L2 of the moment arm indicated by a two-dot chain line from the center of gravity position G2 of the second blade 28 to the rotation fulcrum P. expressed. A relational expression of W1 <W2 is established for the weights of the first blade 26 and the second blade 28, and a relational expression of L1> L2 is established for the lengths of the moment arms of the first blade 26 and the second blade 28. Yes.
FIG. 4 is a top view of the disposer 1 in the initial stage of crushing the porridge.

  At this stage, the cake has a large diameter and is an aggregate of many solids and tends to be soft and easily pulverized. As shown in FIG. 4, it is assumed that the disposer 1 is started in a state where the large-diameter container X1 is placed on the turntable 6 between the fixed blade 14 and the first blade 26. At this time, the large-diameter bowl X1 is pressed against the fixed blade 14 by the centrifugal force acting on the large-diameter bowl X1 itself as the turntable 6 rotates.

  Further, when the centrifugal force due to the rotation of the turntable 6 acts on the swing hammer 16, the blade portion 24 is separated from the fixed blade 14 and tilted inwardly on the mounting pin 18 side (inclined state in the blade portion). 3), the large-diameter rod X1 is sandwiched between the fixed blade 14 and the first blade 26 by the rotational force in the rotation direction B in which the swing hammer 16 tries to rotate in the blade-opening state shown in FIG. The first blade 26 is pressed against the large-diameter container X1.

  That is, the large-diameter frame X1 has a pressing force F1 to the fixed blade 14 based on the centrifugal force acting on the large-diameter frame X1 (rotation normal direction from the rotation fulcrum P) and the swing hammer 16 The pressing force F2 (inclination direction from the rotation fulcrum P to the outside) by the first blade 26 based on the rotational force and the frictional force F3 (rotation) caused by the large-diameter rod X1 coming into contact with the unevenness of the fixed blade 14 Crushed into a smaller-diameter container X2 by a reverse rotation tangent direction opposite to the direction B).

  FIG. 5 is a top view of the disposer 1 in the final stage of crushing the porridge. At this stage, the porridge has a small diameter and is an aggregate of a small amount of solid matter, and tends to be hard and hard to be crushed including bones. It is assumed that the small-diameter rod Y1 is in contact with the second blade 28 in the state where the blade portion is open. At this time, the small-diameter rod Y1 is pressed against the fixed blade 14 by the centrifugal force acting on the small-diameter rod Y1 itself by the rotation of the turntable 6, and the small-diameter rod Y1 is further rotated by the swing hammer 16 of the turntable 6. Receiving a centrifugal force due to the reaction force to maintain the blade part open state.

  That is, the small-diameter rod Y1 has a pressing force F4 (the direction of the rotation normal from the rotation fulcrum P to the outside) based on the centrifugal force acting on the small-diameter rod Y1, and the swing hammer 16 has a blade. Due to the pressing force F5 (rotation tangent direction of the rotation direction B) by the second blade 28 based on the reaction force to maintain the outside open state, and the small-diameter rod Y1 is in contact with the unevenness of the fixed blade 14. By the frictional force F6 (the reverse rotation tangent direction opposite to the rotation direction B), it is crushed into a smaller-diameter container Y2.

  FIG. 6 is a top view of the disposer 1 in the case where the small-diameter article to be pulverized in the final stage of pulverization is a hard small-diameter article that is not easily crushed by the fixed blade 14. It is assumed that the hard small-diameter frame Z1 is in contact with the first blade 26 with a distance D1 between the blades in an inclined state in the blade portion. At this time, as in the case of crushing the large-diameter rod X1 described with reference to FIG. 4, the hard small-diameter rod Z1 is pressed against the fixed blade 14 based on the centrifugal force acting on the hard small-diameter rod Z1. The pressure F7, the pressing force F8 by the first blade 26 based on the rotational force of the swing hammer 16, and the frictional force F9 due to the hard small-diameter frame Z1 coming into contact with the unevenness of the fixed blade 14 act. Even if these three-direction forces F7 to F9 act on the hard small-diameter frame Z1, if the hard small-diameter frame Z1 is not crushed, it is based on the reaction force caused by the impact when the hard small-diameter frame Z1 is about to be crushed. The pressing force F10 acts on the first blade 26.

  FIG. 7 is a top view of the disposer 1 after the pressing force F10 by the hard small-diameter frame Z1 acts on the first blade 26. FIG. The rotational direction B of the pressing force F10 acting on the first blade 26 is greater than the rotational force in which the swing hammer 16 receives centrifugal force due to the rotation of the turntable 6 and rotates from the blade inward tilted state to the blade outer open state. It is assumed that the component force in the reverse rotation direction C opposite to is large. At this time, as shown in FIG. 7, the swing hammer 16 is slightly rotated in the reverse rotation direction C, and the blade between the first blade 26 and the fixed blade 14 is larger than the distance D1 between the blades shown in FIG. The gap D2 is formed, and the hard small-diameter frame Z1 can temporarily pass through the gap D2 between the blades.

  FIG. 8 shows a top view of the disposer 1 when the swing hammer 16 is rotated from the state in which the blade portion is inclined in FIG. 7 to the state in which the blade portion is opened when the hard small-diameter frame Z1 is to be crushed. As described above, the rotational moments M1 and M2 around the rotation fulcrum P of the first blade 26 and the second blade 28 are the same, and the swing hammer 16 as a whole is balanced in weight. 7 is rapidly rotated in the rotation direction B from the inwardly inclined state of the blade portion shown in FIG.

  At this time, as in the case of crushing the small-diameter rod Y1 described with reference to FIG. 5, the pressing force F11 to the fixed blade 14 based on the centrifugal force acting on the small-diameter rod Y1 and the swing hammer 16 are the blade portion. Due to the pressing force F12 by the second blade 28 based on the reaction force to maintain the outer open state and the frictional force F13 due to the small-diameter rod Y1 coming into contact with the irregularities of the fixed blade 14, the hard small-diameter rod having a smaller diameter It is ground into the object Z2.

  As described above, according to the disposer 1 of the present embodiment, the blade portion 24 of the swing hammer 16 has the first blade 26 and the second blade 28 so that the single article is efficiently crushed by the single swing hammer 16. be able to. Specifically, since the first blade 26 is lighter than the second blade 28 and the moment arm is long, the large-diameter container X1 moved to the position of the swing hammer 16 in the initial stage of pulverization is replaced with the long first blade 26. It can be sandwiched between the fixed blades 14 and pulverized. The large-diameter container X1 at the initial stage of pulverization is an aggregate of many solids and tends to be soft and easily pulverized. Therefore, even when the first blade 26 is light, it is sandwiched between the fixed blade 14 and efficient. Can be crushed.

  In addition, the first blade 26 has a shape having a protruding portion 26a that protrudes from the mounting portion 22 on the rotation direction A side in the blade portion open state, and the first blade 26 has a large diameter ridge at the protruding portion 26a in the blade portion inwardly inclined state. By contacting the object X1, in addition to the pressing force F1 and the frictional force F3, the pressing force F2 having an action direction completely different from the pressing force F1 and the frictional force F3 can be applied to the large-diameter rod X1. Therefore, the large-diameter container X1 can be efficiently crushed into the smaller-diameter container X2 as an initial pulverization step.

  On the other hand, the second blade 28 is made of a small diameter Y1 crushed by the first blade 26 or a hard small diameter jar Z1 that is still in the pulverization process at the final stage of pulverization, which is heavier and shorter than the first blade 26. It can be crushed and ground between the two blades 28 and the fixed blade 14. Since the small-diameter rods Y1 and Z1 in the final stage of pulverization are aggregates of a small amount of solids and tend to be hard and hard to be crushed including bones and the like, the second blade 28 is heavier and shorter than the fixed blade 14. It can be pulverized efficiently by grinding.

  In addition, the second blade 28 is shaped so as to have a vertical portion 28a that is perpendicular to the rotational direction A without protruding toward the rotational direction A in the blade portion open state, and the second blade 28 is in the vertical portion in the blade portion open state. By contacting the small-diameter rod Y1 at 28a, in addition to the pressing force F4 and the frictional force F6, the small-diameter rod Y1 can be subjected to the pressing force F5 whose direction of action is opposite to the pressing force F4. By applying two forces having opposite directions of action to the small-diameter bowl Y1, the small-diameter bowl Y1 can be ground into a smaller-diameter bowl Y2 and efficiently crushed as the final pulverization stage.

  Further, the hard small-diameter frame Z1 to which an impact is applied once by the first blade 26 in the state shown in FIG. 6 and the forces F7 to F9 in three directions act is more easily pulverized by the second blade 28, Further, by bringing the second blade 28 into contact with the small-diameter rod Z1 in the state where the blade portion is open, in addition to the pressing force F11 and the frictional force F13, the pressing force F12 whose operating direction is opposite to the pressing force F11 is applied to the small-diameter rod Z1. Can act on. By applying two forces having opposite directions of action to the small-diameter article Z1, the small-diameter article Z1 can be ground into a smaller-diameter article Z2 and efficiently crushed as the final pulverization stage.

Thus, by providing the first blade 26 and the second blade 28 on the swing hammer 16, the large-diameter rod X 1, the small-diameter rod Y 1, and the hard small-diameter rod Z 1 can be selectively selected with one swing hammer 16. Since it can grind | pulverize efficiently, the grinding | pulverization loss in the disposer 1 can be reduced significantly.
Moreover, since the rotational moments M1 and M2 around the rotation fulcrum P of the first blade 26 and the second blade 28 are the same, the first blade 26 and the second blade 28 based on the rotation fulcrum P of the swing hammer 16 are used. The rotational moments M1 and M2 can be balanced. Therefore, even when a plurality of blades are formed on the blade portion 24, it is possible to prevent the swing hammer 16 from being obstructed by the weight imbalance of the swing hammer 16.

  Further, even if the swing hammer 16 is rotated from the blade outer open state to the blade inner tilted state by the collision of the hard small-diameter rod Z1 with the blade portion 24, the centrifugal force acting on the swing hammer 16 causes the outside of the blade portion. It can be quickly returned to the open state. Accordingly, the first blade 26 and the second blade 28 suppress the phenomenon of repeated swinging of the swing hammer 16, the reaction slipping phenomenon of the whole of the swing hammer 16 and the complete slipping phenomenon by the first blade 26 and the second blade 28, thereby reducing the grinding loss of the pottery. By performing efficient pulverization, a high-performance disposer 1 can be provided.

The present invention is not limited to the above-described embodiments, and various modifications are possible.
For example, in the above-described embodiment, the blade portion 24 has two blades of the first blade 26 and the second blade 28, but may have three or more blades. Even in this case, the rotation moment M around the rotation fulcrum P of each blade is made the same, and the foremost blade located in front of the turn direction A of the turntable 6 among each blade is the front blade of each blade. If the moment arm is lighter and longer than the plurality of rear blades located on the rear side of the front blade in the turning direction of the turntable 6, the protrusion is formed on the front blade and the vertical portion is formed on the rear blade, the above-described As in the above, the loss of crushing of the porridge is reduced, and efficient crushing can be performed.

Further, a plurality of rear blades positioned on the rear side from the front blade are gradually increased in weight in the order of the rotation direction A of the turntable 6 and the moment arm is shortened to form a protrusion on the front blade, and each rear blade If a vertical portion that becomes vertical in a stepwise manner from the inclined portion is formed, it is possible to pulverize the porridge efficiently in a stepwise manner with one swing hammer 16.
Moreover, in the said embodiment, the blade part 24 protrudes to the fixed blade 14 side by the 1st blade 26 which makes | forms the long plate shape which protruded in the rotation direction A by the top view, seeing in the blade part outer open state, and a top view. The second blade 28 having a rectangular shape is configured to have the same rotational moment M around the rotation fulcrum P of each blade, and the front blade is lighter than one or more of the rear blades. The shape of each blade described above is not limited as long as it is a long moment arm, the protrusion 26a is formed on the first blade 26, and the vertical portion 28a is formed on the second blade 28. Further, if this condition is satisfied, the gap D between the blades, the blade height H, and the blade tip shape may be changed. Pulverization can be performed.

  In the above embodiment, the relational expression W1 <W2 is established for the weights of the first blade 26 and the second blade 28, and the lengths of the moment arms of the first blade 26 and the second blade 28 are L1> L2. Although the relational expression is established, the above relational expression does not necessarily have to be established when the boundary between the first blade 26 and the second blade 28 is not strictly determined. Specifically, if the protrusion 26a is formed on the first blade 26 and the vertical portion 28a is formed on the second blade 28, the shapes of the blades may be made different. Further, a difference in weight between the first blade 26 and the second blade 28 may be obtained by mixing and molding different materials. In this case as well, the loss of crushing of the porridge is reduced and efficient as described above. Grinding can be performed.
