Description

  The present invention relates to a cooker that cuts food in a container with a rotating blade or agitates with a rotating stirring blade.

  Patent Documents 1 and 2 and Non-Patent Document 1 disclose that a rotating shaft provided at the center of a bottomed cylindrical container, a blade provided on the rotating shaft, A lever provided outside the container for rotating the shaft, and changing the meshing speed of a plurality of gears provided between the lever shaft and the rotary shaft provided with the blade to change the rotation speed of the blade A manual cooker that can be used is disclosed.

  Patent Documents 1 and 2 are provided with a lid with a bottom lid on the bottom surface so that it can be attached to and detached from the upper part of a cylindrical container with a flat bottom surface, and further supported in a protruding manner above the lid body. In a cooker in which a cutter member is horizontally supported by a rotating shaft suspended toward a central portion in the container so that the handle can be rotated by a handwheel handle through a gear mechanism provided in the lid. In this configuration, a part of the intermediate shaft in the gear mechanism is moved up and down by a knob on the lid so that the rotating shaft can be switched between two stages of high speed and low speed.

  In the configurations of Patent Documents 1 and 2 described above, a part of the intermediate shaft of the gear mechanism is moved up and down to change the gear meshing between the shaft of the lever (handle) and the rotating shaft, whereas the non-patent document 1 has a plurality of shafts for transmitting the rotation of the levers, and each of these shafts is provided with a shaft hole through which the lever can be replaced, and gears of different diameters meshing with each other are provided on the respective peripheral surfaces. The gear meshing between the shaft and the rotating shaft is changed by changing the lever.

  However, since Patent Documents 1 and 2 change the gear configuration (meshing) by moving the intermediate shaft up and down by a knob operation, the high and low speeds of rotation are switched. There is a problem that the end face (in the axial direction) of the tooth crest of the non-moving gear that meshes with the gear collides and does not mesh well, necessitating this fine adjustment and troublesome operation.

  On the other hand, in Non-Patent Document 1, since the gears are meshed in advance, that is, it is not necessary to change the gear meshing by moving the intermediate shaft up and down to switch between high speed and low speed as in Patent Documents 1 and 2. It is necessary to perform forward / reverse operation in the direction of rotating the gear according to the replacement position of the high / medium / low speed lever (for example, according to actual products, high speed and low speed are forward rotation and medium speed is reverse rotation). There is a problem that the operation is difficult for the user to understand.

  Non-Patent Document 1 also includes a hole for inserting food in addition to three holes for replacing the lever. The food is inserted into the hole for inserting the lever, and the lever is inserted into the hole for inserting the food. In addition, there is no structure to block unnecessary holes among these holes, so there is a possibility of inserting a finger by mistake or inadvertent entry of foodstuffs or food waste There are problems with safety and hygiene.

(Daeeoeo) Dianoo Professional Vegetable Chopper Food Onion Slicer Kitchen Tool Manual Food Processor, [online], Started Handling February 27, 2016, Amazon, [Search November 17, 2016], Internet <URL: https: //www.amazon.co.jp/gp/product/B00S6H9UNC/ref=pd_rhf_dp_p_img_1?ie=UTF8&psc=1&refRID=5PZ6PJYD7K6W0MC924AY>

  The problem to be solved is that Patent Documents 1 and 2 are uncertain about the operation of switching between high and low speeds of rotation, and the operation of meshing the gears is troublesome. In addition, since there are many holes for changing levers and holes for inserting foodstuffs, it is difficult to understand what these holes are, and they remain open so that you can accidentally insert a finger or unintentionally The point is that the food waste enters.

  In order to solve the above problems, the present invention provides a container into which food is inserted, a rotating shaft suspended in the center of the container, a blade or a stirring blade provided on the outer periphery of the rotating shaft, and the rotating shaft. In a cooking device comprising a mechanism portion having a gear train to be internally provided and a handle provided for a gear shaft of the gear train, the gear train has a plurality of gears meshed in the mechanism portion in series. An operation hole is formed at each of shaft ends of a plurality of gears having the same rotation direction in the gear train, and the operation hole is exposed from the mechanism portion, and one of the plurality of operation holes is A handle insertion hole that communicates is formed, and a cover that rotatably covers the periphery of the plurality of operation holes exposed in the mechanism portion is provided.

  In the present invention, since the gears are arranged in series and the handle is replaced with an operation hole formed on the shaft of the gear, there is no change in the meshing configuration of the gear and the operation direction (rotation direction) is always the same direction. Therefore, there is an advantage that there is no need to make a fine adjustment for meshing the gears, and for the replacement of the handle, the cover formed with one handle insertion hole is rotated. The operation holes to be selected are communicated with each other, so that unnecessary holes are not exposed, fingers and food materials are not inserted by mistake, and there is no inadvertent intrusion of food waste. There is.

  The cooking device of the present invention has an uncertain operation for switching between high and low rotation speeds and an operation that meshes the gears, and this operation is troublesome. In addition, there are forward and reverse rotation operations of the lever, and the operation is difficult to understand. Because there are many holes for changing levers and holes for inserting ingredients, it is difficult to understand what the holes are, and it remains open, so it is difficult to insert fingers or unintentionally intrusion of food waste Or a mechanism having an internal gear train for rotating a rotating shaft provided with a stirring blade; and a handle provided for the gear shaft of the gear train; A handle that is meshed with the inside, has an operation hole formed at each shaft end of a plurality of gears having the same rotation direction in the gear train, is exposed from the mechanism portion, and communicates with one of the plurality of operation holes. An insertion hole is formed and the mechanism A plurality of operation hole of has been resolved by providing a cover for covering rotatably around exposed.

  Furthermore, the cooker of this invention is good also as a structure which provides a stirring blade detachably with respect to a rotating shaft, when a blade is provided in the outer periphery of the rotating shaft in the said structure. By providing this stirring blade, it is possible to mix with the stirring blade while cutting the food by the rotation of the blade. Moreover, since this stirring blade is detachable with respect to the outer periphery of the rotating shaft, it can be attached and detached as necessary, and it is not necessary to remove the blade (it is not configured to provide the stirring blade instead of the blade). , Safe.

  Further, in the above-described configuration, the cooker of the present invention has a handle insertion hole and a plurality of operation holes between the part of the inner periphery of the cover and the periphery of the mechanism portion where the plurality of operation holes are exposed. A positioning mechanism that stops the rotation of the cover at a position where one of them communicates may be provided. By doing so, the insertion hole of the cover and the operation hole exposed from the mechanism part can be reliably communicated, and the lever can be easily inserted.

  Hereinafter, with reference to FIGS. 1-12, the Example of the cooking appliance of this invention is described. Reference numeral 1 denotes a cooker that manually cuts food finely. In this example, the cooker has the following configuration, for example. In this example, as shown in FIG. 1 to FIG. 3, the cooking device 1 is roughly composed of a container 2 into which ingredients are inserted, a rotating shaft 3 suspended in the center of the container 2, and the rotating shaft 3. For example, a blade 4 provided on the outer periphery in a fixed manner (meaning that it cannot be removed except for cleaning and replacement), a mechanism 6 having a gear train 5 for rotating the rotary shaft 3 therein, and a gear train 5 Handle 7 provided with respect to the shaft of the gear, a rotatable cover 8 provided on the mechanism portion 6, and a positioning mechanism 9 provided between a part of the inner periphery of the cover 8 and the periphery of the mechanism portion 7. And a stirring blade 10 that is detachably provided on the outer periphery of the rotating shaft 3, for example.

  FIG. 5 shows the container 2 in detail. The container 2 has a bottom and is substantially cylindrical, and a handle 2a is formed on a part of the outer peripheral surface at the upper end when the opening is the upper surface. Further, the container 2 is formed with a spout 2b extending from the inner peripheral surface to the outer peripheral surface at a diameter facing position where the handle 2a is formed. Furthermore, the container 2 is provided with leg portions 2c on the outer bottom surface.

  Further, in this example, the container 2 is configured such that a lid 2A (FIG. 6) is provided at the opening so as to be freely opened and closed, and the inner periphery of the upper edge of the opening is equiangularly spaced from the peripheral edge of the lid 2A. A plurality of engaging projections 2d having a shape matching the plurality of engaging recesses 2Aa are formed at equiangular intervals.

  Further, the container 2 is formed with protruding portions 2e that protrude toward the center and extend in the axial direction at equal intervals on the inner peripheral surface. The protrusion 2e is for locking the food so that the food rotates together with the rotating blade 4 to be described later so that the so-called food does not escape from the blade 4.

  In addition, the container 2 is formed with a shaft body 2B that protrudes toward the opening side at the center position of the inner bottom surface. This shaft body 2B is for fitting a rotating shaft 3 (FIG. 7) provided with a blade 4 described later.

  FIG. 6 shows the lid 2A for closing the opening of the container 2 in detail. As described above, the lid 2A is formed with the engagement recess 2Aa that coincides with the engagement projection 2d of the container 2 at the periphery, and a portion other than the engagement recess 2Aa is a lid 6B of the mechanism unit 6 described later. The engaging portion 2Ab is pressed down by the lower surface of the lock portion 6Bd.

  Further, the lid 2A is formed with a shaft hole 2Ac penetrating the front and back surfaces at the center. This shaft shelf 2Ac is formed so that the upper end part of the below-mentioned rotating shaft 3 may penetrate. Further, a skirt 2Ad that fits inside the opening of the container 2 is formed on the lower surface side of the engagement recess 2Aa, and a recess 2Ae into which the protrusion 2e of the container 2 is inserted is formed in the skirt 2Ad.

  The lid 2A and the container 2 can be detached from the container 2 in a state where the position of the engaging recess 2Aa and the position of the engaging convex portion 2d of the container 2 coincide with each other by rotating the lid 2A. The engaging portion 2Ab of the lid 2A is positioned below by further sinking in a state where the recessed portion 2Ae and the protruding portion 2e of the container 2 are matched after being matched with the engaging convex portion 2d of the container 2.

  Therefore, the cooker 1 in this example is not configured to lock or unlock the closed state by rotating the lid 2A with respect to the container 2, but in a state where the lid 2A is mounted, It is configured to unlock.

  In addition, the cooking device 1 of the present invention has the lid 2A, so that the mechanism unit 6 and the handle 7 can be removed from the container 2, that is, stored in the refrigerator with a reduced height. At this time, if the rotating shaft 3 is left in the container 2, the shaft hole 2Ac of the lid 2A can be closed.

  Furthermore, by having the lid 2 </ b> A, food that scatters at the time of cooking does not adhere to the mechanism portion 6, so that the trouble of washing the mechanism portion 6 can be saved. In this regard, for example, when the mechanism portion 6 is washed after cooking in a configuration in which the cover 2A is not provided and the residue of the food material adheres to the mechanism portion 6, the residue of the food material does not wash off well and is unsatisfactory in terms of hygiene. If it remains inside, mold may occur, which is unsanitary. Therefore, the lid 2A is not only very easily stored in the refrigerator, but also has an effect of improving hygiene safety.

  FIG. 7 shows the rotating shaft 3 and the blade 4 in detail. In this example, the rotating shaft 3 has a cylindrical shaft shape that gradually increases in diameter downward (toward the bottom surface of the container 2). The opening shape on the upper end (opening side in the container 2) side of the rotating shaft 3 is engaged with a rectangular cross section at the lower end of the low-speed gear 5A described later and has a corner, for example, a rectangular shape in this example. The opening 3a is formed. On the other hand, the rotary shaft 3 is formed with a fitting opening 3b in which the opening shape on the cylindrical shaft-like lower end (inner bottom surface side in the container 2) is a circle into which the shaft body 2B is fitted. Has been.

  Attachment portions 3c and 3c for attaching the blades 4 and 4 are formed at opposing positions in the diametrical direction on the side peripheral surface of the lower end of the rotary shaft 3. The attachment portion 3c is for screwing the blades 4 and 4. Each of the blades 4 and 4 has an arc shape and a tapered shape, a blade surface 4a is formed on the outer arc, and communicates with the mounting portion 3c on the opposite side to the tapered side. A screw insertion hole 4b is formed.

  Furthermore, in this example, the rotation shaft 3 is formed with positioning ribs 3d and 3e for preventing free rotation of the stirring blade 10 at a substantially diameter-opposing position on the outer peripheral surface. The positioning ribs 3d and 3e are substantially semicircular in a plan view (as viewed from the side of the engagement opening 3a in the rotating shaft 3), and extend in the axial direction of the rotating shaft 3 so as to project from the outer peripheral surface. The shapes are slightly different from each other. That is, the positioning rib 3d is wide in the circumferential direction of the rotating shaft 3 (large diameter), and the positioning rib 3e is narrow in the circumferential direction of the rotating shaft 3 (small diameter).

  As described above, the rotating shaft 3 gradually increases in diameter downward to prevent the wrong mounting in the vertical direction (described later) when the stirring blade 10 is mounted, and the shape of the positioning ribs 3d and 3e. By making these different, it is configured to prevent a mistake in mounting in the circumferential direction (described later) when the stirring blade 10 is mounted.

  8 and 9 show the mechanism unit 6 in detail. The mechanism part 6 is comprised by the main body 6A shown in FIG. 8, and the cover body 6B shown in FIG. The main body 6A has a hollow inner cylinder, that is, the top surface 6Aa is the top surface, and the bottom surface is open. The top surface 6Aa is further formed with a hollow step 6Ab that is hollow and protrudes upward. Yes.

  The step portion 6Ab is formed at a position deviated as a whole from the center of the top surface 6Aa, and a rotation hole 6Ac into which a shaft portion 8a of a cover 8 (FIG. 10) described later is fitted at the center position of the step portion 6Ab. A low speed hole 6Ad and a high speed hole 6Ae are formed linearly in the diametrical direction around the rotation hole 6Ac.

  The low speed hole 6Ad is located at the center of the top surface 6Aa (the rotation hole 6Ac is located at the center of the step portion 6Ab), and the high speed hole 6Ae is located on the peripheral side of the top surface 6Aa via the rotation hole 6Ac. Further, the shaft 7a of the handle 7 is fitted into each of the low speed hole 6Ad and the high speed hole 6Ae, but only one of the handles 7 selectively inserted by the cover 8 is exposed.

  A gear train 5 is inserted in the main body 6A. Here, the gear train 5 inserted in the main body 6A of the mechanism section 6 will be described with reference to FIG. In this example, the gear train 5 is disposed between the low speed gear 5A disposed at the position of the low speed hole 6Ad, the high speed gear 5B disposed at the position of the high speed hole 6Ae, and between the low speed gear 5A and the high speed gear 5B. The intermediate gear 5C is configured to mesh and be arranged in series.

  The low-speed gear 5A and the high-speed gear 5B each have an operation hole 5a on the shaft. These operation holes 5a (shafts) are respectively exposed from the low speed hole 6Ad and the high speed hole 6Ae which are openings formed in the mechanism portion 6, and the shaft body of the handle 7 is passed through the low speed hole 6Ad and the high speed hole 6Ae. 7a can be inserted. Further, each of the operation holes 5a of the low speed gear 5A and the high speed gear 5B has a protrusion 5b formed at the inner periphery, for example, at equal angular intervals toward the center, and the operation hole 5a and the outer peripheral surface of the shaft body 7a of the handle 7 are formed. It is set as the structure engaged so that it may not idle.

  Further, the low speed gear 5A and the high speed gear 5B are flat gears, and the intermediate gear 5C is a step gear. In this example, the large diameter gear 5Ca on the upper side of the intermediate gear 5C meshes with the low speed gear 5A, Side small diameter gear 5Cb meshes with the high speed gear 5B. Further, the lower end of the shaft of the low speed gear 5A, that is, the side opposite to the side where the operation hole 5a is formed, is inserted into the engagement opening 3a of the rotary shaft 3, and the outer peripheral surface of the low speed gear 5A is prevented from spinning idle at this time. The shape is the same as 3a.

  In the main body 6A in which the gear train 5 is inserted, a positioning mechanism 9 is provided at a part of the peripheral edge of the step portion 6Ab. The positioning mechanism 9 includes a handle insertion hole 8b of the cover 8 and one operation hole 5a of the low speed gear 5A or the high speed gear 5B between a recess 8c of the cover 8 shown in FIG. The rotation of the cover 8 is stopped at a position where the cover 8 communicates.

  In this example, a later-described spring member 9A made of an elastically deformable material shown in FIG. 11 is arranged in an arrangement portion 6Af formed in a part of the peripheral portion of the step portion 6Ab. The arrangement portion 6Af is provided at a position rotated by 90 ° with respect to the diameter connecting the center lines of the operation holes 5a of the low speed gear 5A and the high speed gear 5B.

  In addition, the disposing portion 6Af has mounting holes 6Ag and 6Ag into which the mounting portions 9c of the spring member 9A are inserted at both ends in the circumferential direction, and guides the spring member 9A radially outward to a central portion between the mounting holes 6Ag and 6Ag. The guide protrusion 6Ah is formed.

  Here, the spring member 9A shown in detail in FIG. 11 will be described. The spring member 9A has arc portions 9a, 9a that are elastically deformed and restored at both ends, a tip portion 9b at the center between the arc portions 9a, 9a, and a mounting hole 6Ag at one end in the height direction of the arc portions 9a, 9a. The attachment parts 9c and 9c to be inserted into the guide part 9d are formed on the side where the attachment parts 9c and 9c are formed on the rear end side of the tip part 9b.

  The spring member 9A is arranged such that the attachment parts 9c, 9c are inserted into the attachment holes 6Ag, 6Ag of the arrangement part 6Af, and the guide part 9d is inserted into the guide protrusion 6Af of the arrangement part 6Af. In the spring member 9A, both the arc parts 9a are bent, the tip part 9b is moved to the center side of the step part 6Ab, and both the arc parts 9a are elastically restored so that the tip part 9b is the step part 6Ab. Protrusively outward. When the distal end portion 9b of the spring member 9A is elastically restored, it engages with a recess 8c of a cover 8 (FIG. 10) described later.

  In this way, in this example, the arrangement relationship between the spring member 9A and the arrangement portion 6Af is such that the guide portion 9d is guided by the guide protrusion 6Af and guides the spring member 9A only in the radial direction. Even if it is made, the position does not shift, and there is an effect that it operates stably.

  The lid 6B of the mechanism unit 6 shown in FIG. 9 is screwed to the lower surface of the main body 6A. A connection hole 6Ba is formed in the upper surface (the side facing the main body 6A) of the lid 6B so that the shaft of the low-speed gear 5A is exposed at the center, and the lower ends of the shafts of the high-speed gear 5B and the intermediate gear 5C are positioned. A receiving bearing 6Bb is formed.

  Further, a short cylindrical insertion portion 6Bc to be inserted into the opening of the container 2 is formed on the side peripheral surface of the lid body 6B. A part of the peripheral surface of the insertion portion 6B is formed from one direction in the circumferential direction. Lock portions 6Bd that are inclined upward in the other direction and protrude in the radially outward direction are formed at equal angular intervals.

  This lock portion 6Bd is used to lock and unlock the entire mechanism portion 6 with respect to the container 2 in which the lid 2A is disposed. That is, the lid 2A is only on (inserted) on the container 2 as described above, and when the cooker 1 is turned upside down, the lid 2A is removed, but is locked by the mechanism unit 6. In this case, even if the cooking device 1 is turned upside down, the mechanism 6 is not detached from the container 2 together with the lid 2A.

  That is, in a state in which the engaging portion 2Ab of the lid 2A is positioned below the engaging convex portion 2d of the container 2 in the axial direction after the engaging concave portion 2Aa of the lid 2A matches the engaging convex portion 2d of the container 2. Then, the insertion portion 6Bc is inserted into the container 2 so as not to come into contact with the engagement convex portion 2d, the lock portion 6Bd is positioned below the engagement convex portion 2d in the axial direction, and the mechanism portion 6 is rotated from this state. Locking is performed by the upper surface of the slope portion protruding in the radially outward direction of the lock portion 6Bd coming into strong contact with the lower surface of the engagement convex portion 2d as the mechanism portion 6 rotates. When the mechanism portion 6 is rotated in the reverse direction, the contact between the lower surface of the engaging convex portion 2d and the lock portion 6Bd becomes weak, and the unlocked state is established.

  FIG. 10 shows the cover 8 in detail. The cover 8 is in the shape of a short tube, and a shaft portion 8a pivotally supported by the rotation hole 6Ac in the main body 6A of the mechanism portion 6 is formed at the center of the back surface of the upper surface (the surface opposite to the mechanism portion 6). ing. Further, the cover 8 is formed with a handle insertion hole 8b communicating with one operation hole 5a of the low speed gear 5A or the high speed gear 5B by rotating the cover 8.

  Further, the cover 8 has a concave portion 8c on the inner peripheral surface of the cylindrical portion, and in this example, the cover 8 is opposed to a position of 90 ° with respect to the diameter connecting the center of the handle insertion hole 8b and the center of the cover 8 (2 Place) is formed. The concave portion 8c is engaged with and engaged with the distal end portion 9b of the elastic restoring state of the spring member 9A of the positioning mechanism 9 described above.

  When the cover 8 is rotated with respect to the step portion 6Ab of the mechanism portion 6 and both arc portions 9a of the spring member 9A are bent during rotation, the tip portion 9b is moved to the center side and reaches the recess 8c. Both arc portions 9a are elastically restored, and the tip end portion 9b moves radially outward and fits into the recess 8c to enter a locked state. At this time, the handle operation hole 8b is in communication with the operation hole 5a of either the low speed gear 5A or the high speed gear 5B.

  The handle 7 (see FIG. 3) includes a shaft body 7a inserted into the handle operation hole 8b, an arm portion 7b that extends orthogonally by connecting the shaft body 7a to one end side, and the other end side of the arm portion 7b. The gripping portion 7c is connected. The grip portion 7c is provided with a cap 7d that can rotate freely with respect to the axis.

  FIG. 12 shows the stirring blade 10 in detail. As described above, the stirring blade 10 can be freely attached to and detached from the rotating shaft 3 and is positioned above the blade 4 in the axial direction of the rotating shaft 3 when the stirring blade 10 is mounted. The stirring blade 10 includes a cylindrical tube body 10A, and blades 10B and 10B provided at positions opposite to the diameter of the outer peripheral surface of the tube body 10A.

  The cylindrical body 10A has an inner peripheral shape that gradually increases in diameter from one end on the upper side to the other end on the lower side, like the rotary shaft 3, and extends in the axial direction on the inner peripheral surface. Concave grooves 10a and 10b corresponding to the positioning ribs 3d and 3e of the rotary shaft 3 are formed. That is, the groove 10a is formed with a groove width that is wide in the circumferential direction corresponding to the positioning rib 3d, and the groove 10b is formed with a groove width that is narrow in the circumferential direction corresponding to the positioning rib 3e.

  The blades 10B and 10B are provided at a diameter-opposing position on the outer peripheral surface of the cylindrical body 10A, and at a position rotated approximately 90 degrees in this example with respect to the blades 4 and 4 on the rotary shaft 3. That is, the positioning ribs 3d and 3e on the rotating shaft 3 and the concave grooves 10a and 10b on the stirring blade 10 are arranged so that the blades 4 and 4 and the blades 10B and 10B do not overlap vertically in the rotation direction. Yes.

  As shown in FIG. 12D, the blades 10B and 10B have an arc shape in a side view (a state in which the cylindrical body 10A is viewed from the outer diameter side to the inner diameter side). Are formed such that one end on the forward side is located below and the other end on the reverse side in the rotational direction is located above.

  By forming the blades 10B and 10B in this way, the food material shredded by the blades 4 and 4 can ride on the upper surfaces of the blades 10B and 10B, and the stirring blade 10 can be prevented from floating upward due to this riding. Can be agitated softly following the rotation of the rotary shaft 3.

  In addition, by arranging the blades 4 and 4 and the blades 10B and 10B so as not to overlap each other in the rotation direction, food is sandwiched between the blades 4 and 4 and the blades 10B and 10B, so that the blades 4 and 4 and the blade 10B. , 10B is not rotated and stays, and the cutting of the whole food by the blades 4 and 4 and the uniform stirring of the whole food by the blades 10B and 10B are synergistic. An effect can be obtained.

  The stirring blade 10 is gradually increased in diameter from one end that is the upper side in the axial direction of the inner diameter of the cylinder 10A toward the other end that is the lower side, so that the stirring blade 10 is removed from the upper side to the lower side in the axial direction. Even if an attempt is made to mount the rotating shaft 3 whose diameter is gradually changed to the outer diameter in an inverted state, the rotating shaft 3 cannot be mounted to an appropriate axial position, thereby preventing erroneous mounting up and down. In addition, since the agitating blade 10 is formed with the concave grooves 10a and 10b corresponding to the positioning ribs 3d and 3e having different circumferential widths, erroneous mounting in the circumferential direction can be prevented.

  The cooker 1 having the above-described configuration is configured such that after the mechanism 6 and the lid 2A are removed from the container 2, the rotating shaft 3 with the blade 4 attached is inserted and set to be rotatable, and then the food to be cut finely is stored in the container 2 Enter. Thereafter, the lid 2A is fitted into the container 2, and the mechanism portion 6 is further fitted into the container 2 from above the lid 2A and is rotated and locked by strong contact between the lock portion 6Bd and the engaging convex portion 2d. .

  Thereafter, if the blade 4 is rotated at a low speed according to the ingredients and cooking technique, the cover 8 is rotated so that the handle insertion hole 8b of the cover 8 communicates with the operation hole 5a of the low speed gear 5A, and the blade 4 is rotated at a high speed, the cover 8 is rotated so that the handle insertion hole 8b of the cover 8 communicates with the operation hole 5a of the high speed gear 5B.

  The rotation of the cover 8 facilitates the alignment of the operation hole 5a of either the low speed gear 5A or the high speed gear 5B and the handle insertion hole 8b by fitting the distal end portion 9b of the spring member 9A into the recess 8c of the cover 8. Can be done accurately.

  After the above, the shaft 7a of the handle 7 is inserted into the handle insertion hole 8b of the cover 8 which is the only opening on the upper surface of the mechanism portion 6, and the rotating shaft 3 is rotated by turning the handle 7. Accordingly, the blade 4 cuts the food material finely.

  In the case of the configuration of this example, if necessary, the mechanism 6 and the lid 2A are removed from the container 2 and the stirring blade 10 is attached to the rotating shaft 3 if necessary. it can. At this time, in the configuration of the present invention, it is not necessary to remove the blades 4 and 4 (replace the blades 4 and 4 and attach the stirring blade 10), so that the blades 4 and 4 are not touched and can be cooked safely. it can. The cooker 1 of the present invention includes a configuration in which the stirring blades 10 (blades 10B and 10B) are fixedly provided instead of the blades 4 and 4, that is, a configuration dedicated to stirring.

  As described above, the cooker 1 of the present invention has no unnecessary holes on the upper surface of the mechanism unit 6, so that it is possible to insert a finger or a foreign object into the hole to suppress the occurrence of a failure or trouble, and to reduce the amount of food waste. Can be used safely in terms of use and hygiene.

  The cooker 1 of the present invention selects the operation hole 5a for changing the low-speed and high-speed handle 7 by rotating the cover 7, that is, the low-speed gear 5A and the high-speed gear 5B are connected in series via the intermediate gear 5C. Since the meshing arrangement is made, that is, it is not necessary to move the gear meshing structure up and down, the operation is simple (because the rotation direction of the handle 7 is also unified) and easy to handle.
