Description

[Technical field]

[0001] The present disclosure relates to a cutter cover and an electric cooker. [Background technology]

[0002] Various techniques have been disclosed for electric cooking appliances such as food processors, mixers, and juicers. The juicing module for a juicer disclosed in Patent Document 1 includes a container with a juice outlet formed therein, a mesh body located inside the container, a screw located inside the mesh body and squeezing ingredients, a lid part connected to the upper end of the container and formed with an input part into which ingredients are input, and a safety cover rotatably provided on a main input port at the upper end of the input part and movable between a first position and a second position.

[0003] The safety cover includes a first cover part and a second cover part. The first cover part stands up to open the main insertion port in the first position and closes the main insertion port in the second position. The second cover part is integral with the first cover part and, when pressed by a force applied downward in the first position, moves the safety cover to the second position so that the first cover part closes the main insertion port.

[0004] According to this configuration, the size of the input section can be increased to allow input and processing of large materials, and when a person puts his / her hand into the input section, the safety cover is configured to close before the hand reaches the screw below the input section, thereby preventing the risk of a safety accident caused by the expansion of the input section.

[0013] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. The following description of the preferred embodiment is essentially merely illustrative and is in no way intended to limit the present disclosure, its applications, or its uses. In the following description, the direction in which the rotating shaft 3 described below extends may be referred to as the up-down direction.

[0014] (Food processor) Fig. 1 shows a food processor 1 as an electric cooking device in an exploded perspective view. Fig. 2 shows the food processor 1 in an assembled perspective view. The food processor 1 is used to finely chop and mix solid food W to be cooked. As shown in Fig. 1, the food processor 1 comprises a device main body 2, a rotating shaft 3, a container 4, a cutter (attachment) 5, a lid 6, and a cutter cover 40 (see Fig. 5) as an accessory.

[0015] The device main body 2 is formed in a substantially L-shape when viewed from the front, and includes a base portion 2a, a mounting platform portion 2b, a vertical wall portion 2c, a protruding portion 2d, and two switches 2e. The base portion 2a extends horizontally and is placed on a table or the like. The mounting platform portion 2b is provided on the upper portion of the base portion 2a. The vertical wall portion 2c is provided on the upper portion of the base portion 2a so as to be adjacent to the mounting platform portion 2b. The vertical wall portion 2c extends in the vertical direction so as to be higher than the mounting platform portion 2b. The protruding portion 2d protrudes upward from the upper portion of the vertical wall portion 2c. The two switches 2e are provided inside the protruding portion 2d and face the upper side. The two switches 2e are arranged at a distance from each other.

[0016] A rotating shaft 3 extending in the vertical direction is coupled to the mounting table portion 2b of the device body 2. The device body 2 is connected to a power source (not shown), and the rotating shaft 3 is electrically driven by power supplied from the power source to the device body 2. In detail, when two switches 2e are pressed simultaneously, the rotating shaft 3 is rotationally driven.

[0017] The container 4 is made of transparent glass or resin. The container 4 is formed in a cylindrical shape having a bottom 4a and an open top. The food W to be cooked is accommodated inside the container 4. A small cylindrical boss is provided in the center of the bottom 4a, and a through hole 4b is formed in the boss. The rotating shaft 3 can be inserted in the vertical direction through the through hole 4b. A handle 4c is attached to the outer periphery of the container 4. As shown in FIG. 2, the container 4 is placed on the mounting base 2b of the device body 2. At this time, the rotating shaft 3 passes through the through hole 4b and faces the inside of the container 4 (see FIG. 12). In other words, the rotating shaft 3 is disposed inside the container 4.

[0018] The cutter 5 can be connected to the rotating shaft 3. In detail, the cutter 5 is connected to the rotating shaft 3 inside the container 4 in a detachable manner and so as to rotate integrally with the rotating shaft 3.

[0019] Here, the food processor 1 can be arbitrarily replaced with various types of cutters (attachments) 5. Types of cutters 5 include, for example, a "knife cutter 10," a "grater cutter 20," a "coarse (or oni) grater cutter 21," and a "slice cutter 30." Each cutter 10, 20, 21, 30 has a common feature in that it has a shaft portion 11, 20a, 21a, 31 and a blade portion 12, 20b, 21b, 32, which will be described later. In this embodiment, the knife cutter 10 and the slice cutter 30 are mainly used as examples, and will be described in detail later.

[0020] The lid 6 has a substantially disk-shaped lid body 6a and a fitting portion 6b. The center of the lid body 6a is recessed downward. The fitting portion 6b extends from the outer periphery of the lid body 6a toward the outer periphery and then bends downward. The fitting portion 6b opens downward so as to correspond to the protruding portion 2d of the device body 2. The fitting portion 6b is provided with two protrusions (not shown) that protrude downward. As shown in FIG. 2, when the lid body 6a closes the opening of the container 4, the fitting portion 6b fits into the protruding portion 2d. Although not shown, at this time, the two protrusions press two switches 2e simultaneously, causing the rotating shaft 3 to rotate.

[0021] (Knife cutter) 3 is a perspective view of the knife cutter 10. The knife cutter 10 is used to process relatively large food items W, for example, for kneading meat mixture. The knife cutter 10 has a shaft 11 and two blades 12. The shaft 11 can be connected to the rotating shaft 3 of the food processor 1. When the shaft 11 is connected to the rotating shaft 3, the central axis O of the shaft 11 extends vertically coaxially with the central axis of the rotating shaft 3.

[0022] Hereinafter, the direction in which the central axis O of the shaft portion 11 extends will be referred to as the axial direction or the up-down direction. The side in the axial direction that is connected to the rotating shaft 3 will be referred to simply as the lower side. The side opposite the side in the axial direction that is connected to the rotating shaft 3 will be referred to simply as the upper side. The direction perpendicular to the axial direction that moves away from the central axis O will be referred to as the radially outer side or outer periphery side. The direction perpendicular to the axial direction that moves closer to the central axis O will be referred to as the radially inner side or inner periphery side. The rotation direction of the shaft portion 11 (rotating shaft 3) will be referred to as the circumferential direction.

[0023] The shaft portion 11 includes a main body portion 11a, a knob portion 11b, and a constricted portion 11c. The main body portion 11a extends from the lower end in the axial direction to a portion slightly above the middle portion while slightly reducing in diameter. The knob portion 11b is a disk-shaped portion located at the upper end in the axial direction. The constricted portion 11c is provided at the upper end of the shaft portion 11, and more specifically, is adjacent to the lower side of the knob portion 11b.

[0024] A recess 13 facing downward (to the bottom surface) is provided inside the shaft portion 11 (see FIG. 8). A coupling shaft 14 for coupling to the rotating shaft 3 is housed inside the recess 13 (see FIG. 8). The rotating shaft 3 fits into a hole in the coupling shaft 14, whereby the shaft portion 11 is coupled (connected) to the rotating shaft 3 so as to rotate integrally with the rotating shaft 3.

[0025] The grip portion 11b is a portion that the user grasps (pinch) when connecting the knife cutter 10 to the rotating shaft 3 or when releasing the knife cutter 10 from the rotating shaft 3.

[0026] The outer diameter of the constricted portion 11c starts from the upper end of the main body portion 11a and decreases toward the upper side, then turns back halfway and the outer diameter suddenly increases toward the knob portion 11b (the upper end of the shaft portion 11). The minimum outer diameter of the constricted portion 11c is smaller than the outer diameter of the upper end of the main body portion 11a. The minimum outer diameter of the constricted portion 11c is also smaller than the outer diameter of the knob portion 11b. In other words, the constricted portion 11c is a recess that is recessed toward the inner periphery of the shaft portion 11.

[0027] Here, shaft portion 11 is made of resin and is injection molded using a mold. Since shaft portion 11 has narrowed portion 11c, if shaft portion 11 were to be molded as a single unit (one member), the molded shaft portion 11 would not be able to be removed from the mold by normal methods. In other words, narrowed portion 11c is a type of "undercut portion" in mold terminology. For this reason, shaft portion 11 is composed of two members, with a turning point P (see Figure 8) midway through narrowed portion 11c as the boundary.

[0028] The two blade portions 12 are disposed on the outer periphery of the shaft portion 11 and rotate integrally with the shaft portion 11. In particular, the blade portions 12 are fixed to the outer periphery of the shaft portion 11. The blade portions 12 extend from the outer periphery of the shaft portion 11 toward the outer periphery and also extend in the circumferential direction (rotate). The two blade portions 12 are disposed symmetrically at approximately 180° with respect to the central axis O of the shaft portion 11. The blade portions 12 are formed of metal.

[0029] At the lower part of the outer periphery of the shaft part 11 (main body part 11a), two axially long ribs (convex parts, protrusions) 15 protrude toward the outer periphery. The two ribs 15 are arranged symmetrically at approximately 180° with respect to the central axis O of the shaft part 11 (only one of the ribs 15 is shown in FIG. 3). The ribs 15 are for allowing the food W processed in the container 4 to escape.

[0030] (Slice cutter) FIG. 4 shows a perspective view of the slice cutter 30. The slice cutter 30 is used to slice and shred food W, for example, to slice cucumbers or shred cabbage. The slice cutter 30 has a shaft 31, two blades 32, and a disk 33. The shaft 31 can be connected to the rotating shaft 3 of the food processor 1. When the shaft 31 is connected to the rotating shaft 3, the central axis O of the shaft 31 extends in the vertical direction coaxially with the central axis of the rotating shaft 3. In the following, the definitions of directions are based on the example of the knife cutter 10 described above.

[0031] The shaft portion 31 is formed in a thin cylindrical shape as a coupling shaft to be coupled to the rotating shaft 3. The rotating shaft 3 fits into a hole in the shaft portion 31, whereby the shaft portion 31 is coupled (connected) to the rotating shaft 3 so as to rotate integrally with the rotating shaft 3. The shaft portion 31 is formed from resin.

[0032] The disk 33 is disk-shaped and is fixed coaxially to the upper end of the shaft portion 31 so as to rotate integrally with the shaft portion 31. The outer diameter of the disk 33 is larger than that of the shaft portion 31. The disk 33 is made of metal. Two finger holes 33a are formed on both radially outer sides of the center of the disk 33. The finger holes 33a are portions into which the user inserts his or her fingers to grasp (pinch) when connecting the slicing cutter 30 to the rotating shaft 3 or when releasing the slicing cutter 30 from the rotating shaft 3.

[0033] The two blade portions 32 are disposed on the outer periphery of the shaft portion 31 and rotate integrally with the shaft portion 31. In detail, the blade portions 32 are fixed to the disk 33 and extend from approximately the center of the disk 33 (shaft portion 31) toward the outer periphery. One of the two blade portions 32 is a slicing blade portion 32a. The other of the two blade portions 32 is a shredding blade portion 32b. The two blade portions 32 are disposed symmetrically at approximately 180° with respect to the central axis O of the shaft portion 31. The blade portions 32 are formed of metal. A hole is formed in the portion of the disk 33 where the blade portions 32 are fixed to allow the processed food W to escape.

[0034] Although not shown, the shape of the lid 6 used when cooking the food W with the slice cutter 30 is different from the shape of the lid 6 used when cooking the food W with the other cutters 10, 20, 21.

[0035] (Cutter cover) 5 is an exploded perspective view of the cutter cover 40. The cutter cover 40 includes a first housing member 41 and a second housing member 42 as a plurality of housing members. Both the first housing member 41 and the second housing member 42 are made of resin.

[0036] The cutter cover 40 as a whole (when the first housing member 41 and the second housing member 42 are combined) is configured in a cylindrical shape having a central axis O' (see Figs. 6, 9, etc.). The outer diameter of the cutter cover 40 (the first housing member 41 and the second housing member 42) is smaller than the inner diameter of the container 4 of the food processor 1.

[0037] Hereinafter, the direction in which the central axis O' of the cutter cover 40 extends is referred to as the axial direction or the vertical direction. Here, the first housing member 41 and the second housing member 42 can be divided in the axial direction (vertical direction). The first housing member 41 side in the axial direction is referred to as one axial side or lower side. The second housing member 42 side in the axial direction is referred to as the other axial side or upper side. The direction perpendicular to the axial direction that moves away from the central axis O' is referred to as the radial outer side or outer circumferential side. The direction perpendicular to the axial direction that moves closer to the central axis O' is referred to as the radial inner side or inner circumferential side. The circumferential direction of the cutter cover 40 is referred to as the circumferential direction.

[0038] The first housing member 41 is formed in a bowl shape and has a bottom wall portion 41a and an outer peripheral wall portion 41b. The bottom wall portion 41a is in the shape of a circular plate. The outer peripheral wall portion 41b extends upward from the outer peripheral end of the bottom wall portion 41a around the entire circumference of the bottom wall portion 41a. An opening 43 is formed in the upper portion of the first housing member 41. The inner diameter of the first housing member 41 is larger than the outer diameter of each of the cutters 10, 20, 21, and 30.

[0039] The bottom wall portion 41a is provided with a positioning holder 44 for the knife cutter 10 and a positioning protrusion 45 for the slice cutter 30, as will be described in detail later. The positioning holder 44 includes an annular rib 44a and two notches (recesses) 44b provided in an upper portion of the rib 44a. The two notches 44b are disposed symmetrically at approximately 180° with respect to the central axis O'.

[0040] Four engagement grooves 46 are provided on the inner peripheral portion of the outer peripheral wall portion 41b as rotational engagement portions. The engagement grooves 46 extend in the circumferential direction along the inner peripheral portion of the outer peripheral wall portion 41b and are recessed toward the outer periphery. The engagement grooves 46 have a predetermined width. An inlet 46a of the engagement grooves 46 faces one circumferential side (counterclockwise side). The four engagement grooves 46 are disposed at intervals from one another in the circumferential direction (only two engagement grooves 46 are shown in FIG. 5).

[0041] The second housing member 42 is formed in a disk shape corresponding to the opening 43, and covers the opening 43 of the first housing member 41. In detail, the second housing member 42 fits into the opening 43 of the first housing member 41. A shaft through hole (shaft through portion) 47 is provided in the center of the second housing member 42 as a communication portion. The inner diameter of the shaft through hole 47 is larger than the outer diameter of the shaft portions 11, 20a, 21a, and 31 of the cutters 10, 20, 21, and 30. A cylindrical boss portion 48 is provided around the shaft through hole 47. Two finger hook portions 49 are provided on the outer periphery of the boss portion 48. The two finger hook portions 49 are disposed symmetrically at approximately 180° with respect to the central axis O'.

[0042] Two hanging parts 50 are provided on the outer periphery of second accommodating member 42. Hanging parts 50 hang downward from the outer periphery of second accommodating member 42 and extend in the circumferential direction. The two hanging parts 50 are disposed symmetrically at approximately 180° with respect to central axis O' (only one hanging part 50 is shown in FIG. 5).

[0043] Each hanging portion 50 of second accommodating member 42 is provided with two engagement protrusions 51 as rotational engagement portions. That is, there are a total of four engagement protrusions 51 (only two engagement protrusions 51 are shown in FIG. 5). The four engagement protrusions 51 are arranged at intervals from one another in the circumferential direction. Engagement protrusions 51 extend outward from the outer circumferential surface of hanging portion 50. Engagement protrusions 51 are configured to be located at the same height as engagement groove portion 46 when second accommodating member 42 is fitted into opening 43 of first accommodating member 41.

[0044] When the second accommodating member 42 is rotated in the other circumferential direction (clockwise, see arrow F in FIG. 5) with the second accommodating member 42 fitted into the opening 43 of the first accommodating member 41, the engaging protrusion 51 of the second accommodating member 42 enters the engaging groove 46 of the first accommodating member 41, thereby engaging with the engaging groove 46. When rotating the second accommodating member 42, it is advisable to place a finger on the finger hook 49.

[0045] Even if an attempt is made to forcibly remove the second accommodating member 42 upward from the first accommodating member 41 with the engaging protrusion 51 engaged with the engaging groove 46, the engaging protrusion 51 is caught in the engaging groove 46, and therefore the second accommodating member 42 will not be removed from the first accommodating member 41. In this manner, the engaging groove 46 and the engaging protrusion 51 are engaged with the mating side (the engaging protrusion 51, the engaging groove 46) by being rotated relative to each other in the circumferential direction.

[0046] A number of small mesh-like holes 52 are provided as communication parts in the bottom wall 41a of the first housing member 41. Similarly, a number of small mesh-like holes 52 are provided as communication parts in the outer peripheral wall 41b of the first housing member 41. Similarly, a number of small mesh-like holes 52 are provided as communication parts in the second housing member 42. The small holes 52 are preferably as large as possible so that fingers cannot be inserted therein.

[0047] When the second housing member 42 covers the opening 43 of the first housing member 41, a housing space (closed space) 53 surrounded by the first housing member 41 and the second housing member 42 is formed inside the cutter cover 40. The housing space 53 is for housing the blade portions 12, 20b, 21b, and 32 of the cutters 10, 20, 21, and 30.

[0048] The shaft through hole 47 and the small hole 52 serving as communication portions communicate the inside and outside of the accommodation space 53 .

[0049] (Storing the knife cutter in the cutter cover) Fig. 6 is a perspective view showing the state in which the blade portion 12 of the knife cutter 10 is housed in the cutter cover 40. Fig. 7 is a plan view seen from above showing the state in which the blade portion 12 of the knife cutter 10 is housed in the cutter cover 40. Fig. 8 is a front cross-sectional view taken along line VIII-VIII showing the state in which the blade portion 12 of the knife cutter 10 is housed in the cutter cover 40.

[0050] As shown in FIGS. 6 to 8, the blade portion 12 of the knife cutter 10 is accommodated in the accommodation space 53 of the cutter cover 40. The knife cutter 10 is positioned by a positioning holder 44 (see FIG. 5) in the bottom wall portion 41a of the first accommodation member 41. In detail, the body portion 11a of the shaft portion 11 of the knife cutter 10 fits into the annular rib 44a of the positioning holder 44, thereby positioning the knife cutter 10 in the radial direction. As a result, the central axis O of the knife cutter 10 and the central axis O' of the cutter cover 40 coincide with each other. Furthermore, the two ribs 15 of the knife cutter 10 fit into the two cutouts 44b of the positioning holder 44, thereby positioning the knife cutter 10 in the circumferential direction.

[0051] The bottom wall portion 41a of the first housing member 41 covers the blade portion 12 of the knife cutter 10 from below (one axial side). The outer peripheral wall portion 41b of the first housing member 41 covers the blade portion 12 of the knife cutter 10 from the outer peripheral side (radial outer side) over the entire circumference (360°). The second housing member 42 fits into the opening 43 of the first housing member 41 to cover the blade portion 12 of the knife cutter 10 from above (the other axial side).

[0052] That is, the first housing member 41 and the second housing member 42 cover the blade portion 12 of the knife cutter 10 from both axial outer sides and the outer circumferential side (radial outer side) of the shaft portion 11.

[0053] An upper portion (the knob portion 11b and the narrowed portion 11c) of the shaft portion 11 of the knife cutter 10 passes through the shaft through-hole 47 of the second housing member 42 and extends upward.

[0054] By rotating the engagement protrusion 51 (see FIG. 5) of the second accommodating member 42 relative to the engagement groove 46 (see FIG. 5) of the first accommodating member 41 toward the other circumferential side of the shaft portion 11 (clockwise, see arrow F in FIG. 7), the engagement protrusion 51 of the second accommodating member 42 is engaged with the mating engagement groove 46 of the first accommodating member 41. In other words, the engagement groove 46 and the engagement protrusion 51 are rotated relative to each other in the circumferential direction of the shaft portion 11, thereby engaging with the mating side (the engagement protrusion 51, the engagement groove 46).

[0055] (Storing the slice cutter in the cutter cover) Fig. 9 is a perspective view showing the state in which the blade portion 32 of the slice cutter 30 is housed in the cutter cover 40. Fig. 10 is a plan view seen from above showing the state in which the blade portion 32 of the slice cutter 30 is housed in the cutter cover 40. Fig. 11 is a front cross-sectional view taken along line XI-XI showing the state in which the blade portion 32 of the slice cutter 30 is housed in the cutter cover 40.

[0056] 9 to 11, the blade portion 32 and the disk 33 of the slice cutter 30 are housed upside down in the housing space 53 of the cutter cover 40. The disk 33 of the slice cutter 30 is positioned by fitting the positioning protrusion 45 (see FIG. 5) on the bottom wall portion 41a of the first housing member 41 into the finger hole portion 33a. As a result, the central axis O of the slice cutter 30 and the central axis O' of the cutter cover 40 coincide with each other.

[0057] The bottom wall 41a of the first housing member 41 covers the blade portion 32 of the slice cutter 30 from below (one axial side). The outer peripheral wall 41b of the first housing member 41 covers the blade portion 32 of the slice cutter 30 from the outer peripheral side (radial outside) over the entire circumference (360°). The second housing member 42 fits into the opening 43 of the first housing member 41 to cover the blade portion 32 of the slice cutter 30 from above (the other axial side).

[0058] That is, the first housing member 41 and the second housing member 42 cover the blade portion 32 of the slice cutter 30 from both axial outer sides and the outer circumferential side (radial outer side) of the shaft portion 31.

[0059] The shaft portion 31 of the slice cutter 30 passes through the shaft through-hole 47 of the second housing member 42 and extends upward.

[0060] Other storage aspects are the same as those of the knife cutter 30, so detailed explanations will be omitted.

[0061] (Storage of the grater cutter and coarse grater cutter in the cutter cover) Although not shown, the first housing member 41 and the second housing member 42 may cover the blade portions 20b, 21b of the grater cutter 20 and the coarse grater cutter 21 from both axial outer sides and the outer circumferential side (radial outer side) of the shaft portions 20a, 21a.

[0062] (Storing the cutter cover in the container) 12 is a front cross-sectional view showing the state in which the cutter cover 40 is accommodated in the container 4 of the food processor 1. As described above, the outer diameter of the cutter cover 40 is smaller than the inner diameter of the container 4, so the cutter cover 40 can be accommodated in the container 4. In detail, the cutter cover 40 is placed upside down above the knife cutter 10 connected to the rotating shaft 3 in the container 4. Then, the shaft portion 11 of the knife cutter 10 is inserted from below into the shaft through hole 47 of the second accommodation member 42 of the cutter cover 40. The shaft portion 11 of the knife cutter 10 faces the accommodation space 53 of the cutter cover 40.

[0063] When the rotating shaft 3 is driven to rotate, the cutter cover 40 may rotate together with the knife cutter 10. However, since the outer diameter of the cutter cover 40 is smaller than the inner diameter of the container 4, the cutter cover 40 hardly rubs against the inner peripheral surface of the container 4. In addition, since the cutter cover 40 is made of resin, even if the cutter cover 40 rubs against the inner peripheral surface of the container 4, the inner peripheral surface of the container 4 will not be significantly damaged.

[0064] (Action and effect) The effects of this embodiment will be described using the knife cutter 10 as an example.

[0065] According to this embodiment, the first housing member 41 and the second housing member 42 in the cutter cover 40 cover the blade portion 12 of the knife cutter 10 from both axial outer sides and the outer circumferential side (radial outer side). In addition, the cutter cover 40 is provided with a shaft through hole 47 and a small hole 52 as a communication portion.

[0066] Therefore, even when the blade portion 12 of the knife cutter 10 is covered with the cutter cover 40, the cleaning water from the dishwasher hits the knife cutter 10 (especially the blade portion 12), so the knife cutter 10 can be cleaned using the dishwasher.

[0067] Furthermore, it is possible to prevent the wire rack or other tableware in the dishwasher from being damaged by the blade 12 of the knife cutter 10. Also, when removing the knife cutter 10 from the dishwasher, it is possible to prevent fingers from touching the blade 12 of the knife cutter 10, which is advantageous in terms of safety.

[0068] As described above, the knife cutter 10 of the food processor 1 can be safely washed in a dishwasher.

[0069] Since the accommodation space (closed space) 53 can be formed simply by covering the opening 43 of the first accommodation member 41 with the second accommodation member 42, handling is easy.

[0070] The engagement groove 46 and the engagement protrusion 51 serving as the rotational engagement portion make it difficult for the first accommodating member 41 and the second accommodating member 42 to come apart in the vertical direction, which is advantageous in terms of safety.

[0071] Since the shaft 11 of the knife cutter 10 passes through the shaft through hole 47 of the second housing member 42, the axial (vertical) length of the cutter cover 40 can be reduced. In addition, dirt on the shaft 11 can be removed by cleaning water passing through the shaft through hole 47. In addition, a user can carry the set of the knife cutter 10 and the cutter cover 40 by grasping the shaft 11 (particularly, the knob portion 11b) protruding to the outside of the cutter cover 40 through the shaft through hole 47.

[0072] The above-mentioned effects can also be applied to the grater cutter 20, the coarse grater cutter 21, and the slice cutter 30 other than the knife cutter 10.

[0073] With the knife cutter 10 connected to the rotating shaft 3 inside the container 4 of the food processor 1, the cutter cover 40 can also be stored compactly inside the container 4, so there is no need to store (package) the cutter cover 40 separately when storing or packing the food processor 1. This is advantageous for saving space.

[0074] By appropriately designing the size of the cutter cover 40, only one cutter cover 40 can be used for various cutters (attachments) 10, 20, 21, and 30.

[0075] (Other embodiments) Although the present disclosure has been described above with reference to the preferred embodiments, such description is not limiting, and various modifications are possible.

[0076] The rotational engagement portions 46 and 51 may be omitted. For example, the second accommodating member 42 may simply cover the opening 43 of the first accommodating member 41.

[0077] In the above embodiment, the cutter cover 40 is configured with the bowl-shaped first housing member 41 and the lid-shaped second housing member 42, but is not limited thereto. For example, the cutter cover 40 may be configured by combining two half-shell-shaped housing members with each other. The two half-shell-shaped housing members may have a rotational engagement portion. In addition, the first housing member 41 may be provided with an engagement protrusion portion 51 as the rotational engagement portion, while the second housing member 42 may be provided with an engagement groove portion 46 as the rotational engagement portion.

[0078] The cutter cover 40 may be composed of three or more housing members. For example, a third housing member may be interposed between the first housing member 41 and the second housing member 42 in the above embodiment.

[0079] The direction in which the plurality of housing members are divided is not limited to the axial direction, and for example, the plurality of housing members may be divided in the radial direction.

[0080] The shaft through hole (shaft through portion) 47 may be omitted. The shaft portions 11, 20a, 21a, and 31 may be completely covered by the cutter cover .

[0081] The communicating portions 47, 52 do not need to be provided in all of the housing members, but may be provided in at least one of the housing members. For example, the shaft through hole 47 may be provided in the second housing member 42, while the small hole 52 may not be provided in either the first housing member 41 or the second housing member 42.

[0082] The electric cooking device 1 is not limited to a food processor, but may be, for example, a mixer or a juicer.

[0083] 13 and 14, a plurality of (e.g., two) gripping portions 54 may be provided on the bottom wall portion 41a of the first housing member 41 instead of the plurality of positioning protrusions 45 (see FIGS. 5 and 11) for the slice cutter 30. The gripping portions 54 extend from the upper surface of the bottom wall portion 41a of the first housing member 41 toward the housing space 53 (upper side, the other axial side).

[0084] The grip portion 54 includes a hollow portion 54a and an outer edge portion 54b. The hollow portion 54a faces the outside of the accommodation space 53 at a lower side (one axial side). The outer edge portion 54b surrounds the hollow portion 54a and separates the hollow portion 54a and the accommodation space 53 from each other. In other words, the outer edge portion 54b is interposed between the hollow portion 54a and the accommodation space 53.

[0085] The outer edge portion 54b may be formed integrally with the first housing member 41, or may be attached to the first housing member 41 as a separate member. The portion of the bottom wall portion 41a of the first housing member 41 where the grip portion 54 (hollow portion 54a) is provided is a through hole. The grip portion 54 fits into the finger hole portion 33a of the disc 33 of the slice cutter 30, similar to the positioning protrusion 45 of the above embodiment.

[0086] A finger can be inserted into the hollow portion 54a of the grip portion 54 from the lower side (one axial side). The grip portion 54 is formed in a truncated cone shape. In the truncated cone-shaped grip portion 54, the diameter of the lower base portion is larger than the diameter of the upper base portion. For example, the diameter of the lower base portion is about 20 mm, and the diameter of the upper base portion is about 15 mm. Note that, as long as a finger can be inserted into the hollow portion 54a, each diameter can be appropriately changed. In addition, the shape of the grip portion 54 is not limited to a truncated cone shape, and may be, for example, a rectangular parallelepiped, cone, cylinder, polygonal column, polygonal pyramid, dome, etc. It is preferable that the distance between the two grip portions 54 is smaller than the distance between the thumb and index finger when they are spread apart.

[0087] A user can hold the first housing member 41 by inserting a finger into the hollow portion 54a of the grip portion 54. This allows the user to attach and detach the cutters 10, 30 to and from the first housing member 41 and to attach and detach the second housing member 42 to and from the first housing member 41 while holding the first housing member 41 via the grip portion 54.

[0088] In addition, since the hollow portion 54a and the storage space 53 are separated from each other by the outer edge portion 54b (the outer edge portion 54b is interposed between the hollow portion 54a and the storage space 53), it is possible to prevent the user's fingers inserted into the hollow portion 54a from touching the blade portions 12, 32 of the cutters 10, 30 stored in the storage space 53.

[0089] The grip portion 54 fits into the finger hole portion 33a of the slice cutter 30, whereby the slice cutter 30 can be positioned.

[0090] Although not shown, the gripping portion 54 may extend from the inner circumferential surface of the outer circumferential wall portion 41b of the first accommodating member 41 toward the accommodating space 53 (inner circumferential side, radially inward). In this case, the hollow portion 54a faces the outside of the accommodating space 53 on the outer circumferential side (radially outward). Also, the portion of the outer circumferential wall portion 41b of the first accommodating member 41 where the gripping portion 54 (hollow portion 54a) is provided is a through hole.
