Description

  The present invention relates to a universal grater capable of sliding down a wide variety of materials such as vegetables and fruits, including sticky ones such as natural and Yamato koji.

  As a kind of commercial cooking utensils, an electric grater that slides down ingredients such as radish and garlic is known. This grater includes, for example, a cutter assembly in which a grated blade having a plurality of blade portions for sliding down the material is provided on the surface of a gravitational plate that is rotatably provided, and a motor that rotationally drives the cutter assembly ( A drive unit), a housing that covers the cutter assembly and has a discharge port for discharging the slid down material, and an input cylinder that is provided integrally with the housing and that inputs the material toward the cutter assembly. And a pressing member that presses the material charged into the charging cylinder toward the vicinity of the surface of the cutter assembly, and an engaging portion that locks the tip of the pressing member in the vicinity of the blade edge of the blade portion. It has been done.

  Here, as shown in FIG. 9, the cutter assembly in the conventional grater machine has a recess 2 formed on the surface of a grate plate 1 formed in a disc shape, and a grated blade 3 is inserted into the recess 2. It is constituted by.

  The grated blade 3 is formed in a disk shape having a smaller diameter than the grated plate 1, and a plurality of quadrangular pyramid shaped blade portions 4 are formed on the surface, and the grated blade 1 is supplied onto the rotating grated plate 1. In order to slide down the material, the cutting edge of the blade portion 4 is arranged at least 1 to 2 mm higher than the surface of the grate plate 1.

  Further, the surface of the grate plate 1 is inclined with respect to the horizontal direction, the output shaft from the motor is mounted on the back surface of the grate plate 1, and the exhaust is disposed below the surface of the grate plate 1. There is an exit.

  In the conventional grater having the above-described structure, the grater plate 1 and the grater blade 3 are rotationally driven by the motor, and the material is charged into the throwing cylinder and directed to the surface of the grater plate 1 by the pressing member. And send it in. Thus, the material is pressed toward the surface of the cutter assembly and is slid down by the plurality of blade portions 4 of the grated blade 3.

  Then, the grated material obtained by sliding down the material is scattered into the housing from the clearance between the surface of the grated plate 1 and the outlet side of the input cylinder by the centrifugal force of the grated plate 1 and sequentially. It moves downward (gravity movement) along the inner wall of the housing and is finally discharged from the discharge port.

  By the way, in the conventional grater, since the blade edge of the blade portion 4 of the grater blade 3 protrudes 1 to 2 mm from the surface of the grater plate 1, the blade edge and the edge portion on the outlet side of the charging cylinder during rotation In order to prevent the interference, the clearance between the surface of the grater plate 1 and the edge on the outlet side of the input cylinder must be set to be equal to or greater than the protruding amount of the blade edge.

  Similarly, in the final stage of sliding down, in order to prevent interference between the cutting edge and the front end of the pressing member, the clearance between the front end of the pressing member and the surface of the grate plate 1 is greater than the protruding amount of the cutting edge. As described above, the pressing member needs to be locked by the engaging portion.

  For this reason, when the sliding down is completed, the material (grated waste) having a thickness of approximately the same dimension as the clearance is between the blade edge and the tip of the pressing member locked to the engaging portion. It will remain. And since this pressing member is locked by the said engaging part, since the pressing force from the said pressing member stops acting, this grated waste is the surface of the grate board 1 by the centrifugal force of the grate board 1 And the clearance from the edge on the outlet side of the charging cylinder, it is blown into the housing, moves downward along the inner wall of the housing together with the grated material, and is discharged from the discharge port. For this reason, the conventional grater has a problem in that the material is wasted by the thickness of the grater.

  Moreover, if the grater material splashed to the inner wall of the housing is a grater material that has a lot of moisture and is easy to move downward (gravity movement), it moves along the inner wall of the housing to the outlet without taking time. Therefore, it is possible to smoothly take out from the outlet. However, since the grated material with low water content is difficult to move downward even if it is scattered on the inner wall of the housing, it may be difficult to take out the material smoothly from the outlet. In addition, particularly sticky grated material adheres to the inner wall of the housing and is difficult to move downward, so that the amount of grated material attached to the upper portion of the inner wall of the housing increases with the progress of sliding down. Finally, a lump of the grated material is formed above the housing. As a result, the lump of grated material wraps around the back side of the grate plate 1 from above the housing, entangles with the output shaft from the motor and rotates together with the output shaft as a result. There were some things that I couldn't do. Furthermore, the above-mentioned grater material fills the housing and can no longer scatter into the housing from the clearance between the surface of the grater plate 1 and the edge on the outlet side of the input cylinder, and finally the above-mentioned input In some cases, the gas flowed back to the inlet side of the cylinder.

  The present invention has been made to solve the problems of the prior art, and can reliably slide down a wide variety of materials such as vegetables and fruits including sticky materials such as natural and Yamato koji. A universal grater.

  In order to solve the above-mentioned problem, the present invention according to claim 1 is provided with a grated blade having a plurality of blade portions for sliding down materials such as vegetables and fruits on the surface of a grated plate provided rotatably. A cutter assembly, a drive unit that rotationally drives the cutter assembly, a housing that covers the cutter assembly and that has a discharge port that discharges the slid down material, and is provided integrally with the housing. An input cylinder for supplying the material toward the cutter assembly, a pressing member for pressing the material input to the input cylinder toward the vicinity of the surface of the cutter assembly, and a tip of the pressing member at the cutter assembly Is provided with an engaging portion to be locked in the vicinity of the surface, and a recess is formed on the surface of the grater plate, The grated blade is inserted into the recess, the cutting edge of the grated blade is disposed 0 mm to 1 mm lower than the surface of the grated plate, and the surface of the grated plate and the outlet of the input cylinder The clearance between the side edge and the tip of the pressing member locked to the engaging portion is set to be 0.2 mm or more and 0.5 mm or less.

  According to a second aspect of the present invention, in the first aspect, the surface of the grater plate is disposed so as to be inclined with respect to the horizontal direction, and the output shaft of the drive unit is attached to the back surface of the grater plate. And a semi-cylindrical cover member that surrounds the upper half of the upper half of the grate plate and covers the upper side of the output shaft of the drive unit. It is characterized by that.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a plurality of metal screw bodies are provided on the front end surface of the pressing member with the pointed ends directed in the pressing direction. It is characterized by being.

  Furthermore, the present invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the grater plate has a chamfered portion or a mortar-shaped inclined surface formed at an edge of the recess. It is characterized by being.

  According to the first aspect of the present invention, the driving plate causes the grate plate and the grated blade to rotate, and the material charged into the charging cylinder is directed to the surface of the cutter assembly rotated by the pressing member. And send it in. Then, the material enters the concave portion from the surface of the grate plate by its own elasticity, and is slid down by the plurality of blade portions. Then, the grated material obtained by sliding down the material, from the clearance between the surface of the grated plate and the edge of the outlet side of the input cylinder into the housing due to the centrifugal force of the grated plate It is scattered and sequentially discharged from the discharge port along the inner wall of the housing.

  At this time, a concave portion is formed on the surface of the grater plate, the grater blade is inserted into the concave portion, and the cutting edge of the blade portion of the grater blade is disposed 0 mm to 1 mm lower than the surface of the grater plate. For this reason, the cutting edge and the edge part on the outlet side of the charging cylinder do not interfere with each other during rotation. In the final stage of sliding down, the cutting edge and the tip of the pressing member do not interfere with each other. For this reason, it becomes possible to make the clearance between the surface of the grate plate and the edge of the outlet side of the input cylinder and the tip of the pressing member locked to the engaging portion as small as possible.

  Thereby, the clearance between the surface of the grater plate and the edge of the outlet side of the input cylinder and the tip of the pressing member when the engaging portion is locked is 0.2 mm or more and 0.5 mm. Since it becomes possible to set so that it becomes the following, it becomes possible to slide down all the said materials, without the said gravel waste remaining. As a result, it is possible to eliminate the waste of the material and to prevent the grated waste from being mixed into the grated material discharged from the discharge port.

  According to the second aspect of the present invention, the surface of the grater plate is disposed so as to be inclined with respect to the horizontal direction, and the back surface of the grater plate is pivotally attached to the output shaft of the drive unit. Since the discharge port is provided at a position below the surface of the grate plate of the housing, the grate material scattered into the housing by the centrifugal force of the grate plate moves downward along the inner wall of the housing ( And is discharged from the discharge port provided below the surface of the grater plate.

  At this time, since the semi-cylindrical cover member that surrounds the outer periphery of the upper half of the grater plate and covers the upper side of the output shaft of the drive unit is provided, the grater material is guided to the cover member, It is sent to a position below the surface of the grater plate provided with the discharge port. As a result, even a grated material with little moisture can be easily taken out from the outlet. In addition, the grated material with high viscosity will not be lumped into the output shaft on the back side, and will not flow back to the input port side of the input cylinder, so that it can be reliably discharged from the output port. Is possible.

  By the way, if the pressing member of the conventional grater machine has a smooth tip end surface, even if the material thrown into the charging cylinder is pressed, the material rotates with the grated blade as the grated blade rotates. As a result, the material could not be efficiently slid down. For this reason, when molding the pressing member with synthetic resin, a plurality of quadrangular pyramid-shaped convex portions are integrally formed on the tip surface of the pressing member to prevent the material from rotating around the grated blade. It was. However, since the convex portion made of a synthetic resin has a weak force to bite into the material, it has not been possible to reliably prevent the material from rotating around the grated blade.

  On the other hand, according to the third aspect of the present invention, a plurality of metal screw bodies are provided on the tip surface of the pressing member so as to be evenly arranged so that the tip ends in the pressing direction. Therefore, the biting of the material becomes very strong. As a result, it is possible to reliably prevent the material from rotating around the grater blade, and it is possible to efficiently slide down the material.

  By the way, even if the edge of the recess of the grater plate is formed at a right angle, in the case of an elastic material, it can enter the recess due to its elasticity, but in the case of a relatively hard material, the blade In some cases, the blade can only enter the blade edge of the part, and cannot be slid down by the entire blade part.

  Therefore, the inventor forms an inclination from the surface of the grater plate toward the base side of the blade portion, and moves the material toward the base side of the blade portion, so that the blade portion can be made of any material. It came to the knowledge that it became possible to slide down efficiently as a whole.

  The present invention according to claim 4 is made based on the above knowledge, and since the chamfered portion or the mortar-shaped inclined surface is formed at the edge of the concave portion of the grater plate, the material is The chamfered portion or the inclined surface moves to the base side of the blade portion of the grated blade. As a result, any material can be sunk into the entire blade portion and slid down, and as a result, the material can be slid down efficiently.

A chamfered portion 18 is formed as shown in a). In the present embodiment, the chamfered portion 18 is formed. However, as shown in FIG. 7B, a mortar-shaped inclined surface 19 may be formed.

  On the other hand, as shown in FIG. 3, on the surface around the through hole not covered with the cover 13 of the mounting plate 12, the center axis of the first gear 20 surrounds the output shaft 10 so that the center axis line is the output shaft. It is fixed to coincide with the 10 axis. A concave portion is formed on the back surface of the rotating member 14. The second gear is engaged with the first gear 20 in the concave portion and revolves along the first gear 20 when the rotating member 14 rotates. Is rotatably provided. Further, a concave portion having a circular shape in plan view is formed on the surface of the rotating member 14, and a disk-shaped rotating body is rotatably accommodated in the concave portion, and the central axis of the rotating body is the second axis. It is fixed to the central axis of the gear. A cutter assembly 22 is constituted by a disc-shaped grated blade 21 being rotatably accommodated in the concave portion 17 of the grate plate 15, and the central axis of the rotating body is the central axis of the grated blade 21. Is fixed.

  Thereby, when the output shaft 10 rotates and the rotating member 14 rotates, the second gear revolves along the outer periphery of the first gear 20, and the rotating body fixed to the second gear rotates, When the grated blade 21 fixed to the rotating body is rotationally driven, the grated blade 21 is rotationally driven around its central axis in the recess 17 of the rotating grate plate 15.

  Here, as shown in FIG. 4, the grated blade 21 has a plurality of (68 in the figure) square pyramid-shaped blade portions 23 arranged on the surface so as to be evenly arranged. The grated blade 21 is housed in the recess 17 so that the cutting edge of the blade portion 23 is flush with the surface of the grated plate 15.

  Further, as shown in FIG. 1, the universal grater according to the present embodiment includes a side wall portion 24 formed in a cylindrical shape slightly smaller than the diameter of the cover 13 and a ceiling for closing the upper opening of the outer side wall portion 24. A housing 26 constituted by a plate portion 25 is provided, and a side wall portion 24 of the housing 26 is detachably provided along the outer periphery of the cover 13. The side wall 24 of the housing 26 is provided with a discharge port 27 for discharging the grated material obtained by sliding down the material at a position below the surface of the grated plate 15. Further, as shown in FIG. 3A, the top plate portion 25 is integrally provided with a charging cylinder 28 for charging the material at a position facing the cutter assembly 22.

  As shown in FIG. 2, the input cylinder 28 is formed in a cylindrical shape having a smaller diameter than the diameter of the grated plate 15, and the axis line is arranged coaxially with the central axis of the grated plate 15. Is provided. A clearance T of 0.2 mm to 0.5 mm for discharging the grated material is provided between the edge on the outlet side of the charging cylinder 28 and the surface of the grated plate 15. In the present embodiment, the clearance T is set to 0.3 mm.

  As shown in FIG. 1, the universal grater according to the present embodiment is provided with a pressing member 29 that presses the material charged in the charging cylinder 28. As shown in FIG. 6, the pressing member 29 is made of a synthetic resin and is formed in a bottomed cylindrical shape having a slightly smaller diameter than the inner diameter of the charging cylinder 28. On the tip surface 30 (bottom), a plurality of (in the figure, 40) square pyramid-shaped convex portions 31 made of synthetic resin are evenly arranged with the tips pointed in the pressing direction so as to protrude integrally. It is installed. Further, a plurality (12 in the figure) of metal screw bodies 32 are provided on the distal end surface 30 so as to be evenly arranged with the tip ends in the pressing direction. Further, at the base end portion of the pressing member 29, when the convex portion 31 and the tip of the screw body 32 reach a position of 0.3 mm from the surface of the grate plate, the base end portion of the pressing member 29 is engaged with the edge portion of the insertion port of the insertion cylinder 27. The engaging portion 33 to be stopped is integrally provided.

  The engaging portion 33 is formed in a ring shape whose inner diameter is the same as the diameter of the pressing member 29, and whose outer diameter is larger than the diameter of the pressing member 29 and the diameter of the edge of the charging port of the charging cylinder 27. . A grip portion 34 of the pressing member 29 is integrally provided on the surface of the engaging portion 33.

Next, the operation of the universal grater having the above configuration will be described.
First, the motor 6 of the drive unit 5 is started, and the flywheel 8 and the output shaft 10 fixed to the outer periphery of the rotor shaft 7 are rotated.

  When the output shaft 10 rotates, the rotating member 14 fixed to the output shaft 10 rotates, and accordingly, the grate plate 15 attached to the rotating member 14 is integrally rotated.

  Further, when the rotating member 14 rotates, the second gear revolves along the outer periphery of the first gear 20, the rotating body fixed to the second gear rotates, and the grated blade 21 fixed to the rotating body. Is rotationally driven, the grater blade 21 is rotationally driven around its central axis in the recess 17 of the grater plate 15.

  Next, after the material is charged into the charging cylinder 28, the material supplied into the charging cylinder 28 is fed toward the surface of the lower plate 15 by the pressing member 29. As a result, the material enters the concave portion 17 from the surface of the grate plate 15 by its own elasticity, and is slid down by the plurality of blade portions 23 of the grated blade 21.

  Next, the grated material obtained by sliding down the material is separated from the clearance T between the surface of the grate plate 15 and the outlet side edge of the input cylinder 28 by the centrifugal force of the grate plate 15 in the housing 26. Splash into. Then, the grated material is guided by the cover member 16 and sent to a lower position on the surface of the grated plate 15, and a discharge port 27 provided in the lower side along the inner side of the side wall portion 24 below the housing 26 sequentially. Discharged from.

  According to the universal grater configured as described above, the recess 17 is formed on the surface of the grate plate 15 and the grated blade 21 is inserted into the recess 17 so that the cutting edge of the blade portion 23 of the grate blade 21 is lowered. 15, the clearance T between the surface of the grate plate 15 and the edge of the outlet side of the insertion cylinder 28 and the tip of the pressing member 29 locked to the engaging portion 33. Can be made as small as possible.

  Thereby, the clearance between the surface of the grate plate 15 and the edge of the outlet cylinder 28 and the protrusion 31 that is the tip of the pressing member 29 locked to the engaging portion 32 and the tip of the screw body 32 is reduced. For example, since it becomes possible to set to 0.3 mm, it becomes possible to slide down all the said materials, without grated waste remaining. As a result, it is possible to eliminate the waste of the material and to prevent the grated waste from being mixed into the grated material discharged from the discharge port 27.

  A semi-cylindrical cover member 16 that surrounds the upper half of the upper side of the grate plate 15 on the surface of the cover 13 that covers the surface of the mounting plate 12 and covers the upper side of the rotating member 14 that is attached to the output shaft 10. Therefore, the grated material is guided by the cover member 16 and is sent to a position below the surface of the grated plate 15. As a result, even a grater material with little moisture can be easily taken out from the outlet 27 smoothly. Further, the grated material having a high viscosity will not be lumped into the output shaft on the back side, and will not flow back to the input port side of the input cylinder, so that it can be reliably discharged from the output port 27. Is possible.

  Further, since the pressing member 29 is provided with twelve metal screw bodies 32 on the distal end surface 30 so as to be evenly arranged so that the tips are directed in the pressing direction, the force to bite the material is extremely high. Become stronger. As a result, it is possible to reliably prevent the material from rotating around the grater blade, and it is possible to efficiently slide down the material.

  Further, since the chamfered portion 18 or the mortar-shaped inclined surface 19 is formed at the edge portion of the concave portion 17 of the grater plate 15, the material is cut by the chamfered portion 18 and the inclined surface 19. It moves to the base side of the part 23. As a result, any material can be sunk into the entire blade portion 23 and slid down, and as a result, the material can be slid down efficiently.

By the way, in general, in this type of grater, the rotational torque acting on the output shaft of the motor fluctuates as a result of intermittently sliding down the material with the grater blade. In particular, when a large number of garlics are slid down at the same time, or when a hard material such as Yamato coffee is slid down, a large load fluctuation occurs intermittently on the output shaft, and a load exceeding the rating of the motor is instantaneously generated. When this occurs, the motor stops and cannot be slid down.
For this reason, a geared motor is usually used as the motor to reduce the rotational speed and increase the rotational torque of the output shaft.

  On the other hand, in the universal grater of this embodiment, since the flywheel 8 is provided on the output shaft 10 of the motor 6, the output shaft caused by the load variation described above due to the inertial force of the flywheel 8 is provided. 10 fluctuations in rotational torque can be absorbed, and stable sliding down can be performed. Moreover, even when a load exceeding the rating of the motor 6 is instantaneously applied to the output shaft 10, the inertial force of the flywheel 8 increases the rotational torque to resist the load, so that the motor 6 is instantaneously It can be prevented from stopping.

  As a result, a general-purpose small motor 6 of about 90 W can be used as the drive unit without using an expensive geared motor or a high-power large motor, which is excellent in economy.

  Further, when the grated blade 21 is provided at the center of the grate plate 15, the material is rotated with the grated blade 21, so that it is difficult to efficiently slide down the material. In this case, since the grated blade 21 is provided at a position that is decentered with respect to the central axis of the grate plate 15, the above-mentioned material does not travel with the grated blade 21. As a result, it becomes possible to sequentially slide down the material, and it is possible to efficiently slide down the material.

  Further, the grated blade 21 is arranged at a position eccentric with respect to the central axis of the grate plate 15, that is, on the outer peripheral side of the grate plate 15, and the input cylinder 28 is formed in a cylindrical shape having a smaller diameter than the diameter of the grate plate 15. Since the central axis is formed so as to be oppositely disposed coaxially with the central axis of the grate plate 15, a part of the outer periphery of the grated blade 21 is provided as shown in FIG. Is located outward from the outer periphery of the charging cylinder 28. Thus, when the grated plate 15 is rotated, a part of the outer periphery of the grated blade 21 moves along the outer periphery of the charging cylinder 28, so that the grated material is efficiently retained without being held in the charging cylinder 28. It can be scattered into the housing 26. As a result, it is possible to prevent stagnation of the charging cylinder 28 of the above-described gratering material due to the reduction in the clearance T.

  Further, since the output shaft 10 protruding from the surface of the mounting plate 12 is made of stainless steel, the corrosion resistance against water is increased. Thereby, even if the material containing moisture is slid down, the output shaft 10 is not rusted, and thus the material can be continuously slid down cleanly.

  In addition, since the stainless steel cover 13 is provided on the surface of the mounting plate 12, the cover 13 can be easily removed and cleaned after the grated material is manufactured. As a result, it is possible to manufacture the grated material in a clean state at all times. Moreover, since the grated material hardly adheres to the attachment plate 12 provided in the opening portion of the drive unit 5, it is possible to clean by wiping with a cloth or the like without using water.
