Embodiment 1.
FIG. 1 is a perspective view showing the appearance of the processing tool according to the first embodiment. FIG. 2 is an exploded perspective view showing the configuration of the processing tool according to the first embodiment. As shown in FIG. 1, the processing instrument according to the first embodiment is an instrument including a container 1, a lid portion 2, and a driving portion 3, which chops and crushes foodstuffs and processes them into small pieces. The container 1 is a dish-shaped container. The foodstuff to be processed is stored in the container 1. The lid 2 is detachably attached to the container 1 so that the food material being processed does not leak to the outside of the container 1. The drive unit 3 generates a driving force used for processing foodstuffs. For example, the drive unit 3 is a projecting portion provided so as to project from the lid portion 2, as shown in FIG.

It is assumed that the processing target of the processing tool according to the first embodiment is not a hard food material such as raw vegetables, but a cooked and relatively soft food material. For example, the processing tool according to the first embodiment is used when making baby food or nursing food from a normal meal. Baby food or long-term care food can be prepared by processing ingredients cooked as a normal meal so as to retain the texture of being chopped with a kitchen knife or crushed with a fork. However, the work of using a kitchen knife or fork to grind the ingredients is time-consuming. On the other hand, in the processing tool according to the first embodiment, the food material can be finely processed more easily than a kitchen knife or a fork.

As shown in FIG. 2, the processing tool according to the first embodiment includes a dish-shaped portion 4 and a connecting member 5. The dish-shaped portion 4 is a dish-shaped metal member having one or a plurality of openings penetrating the bottom surface portion and having a shaft portion at a position coaxial with the center of the bottom surface portion. The connecting member 5 is a circular member that connects the shaft portion of the dish-shaped portion 4 to the driving portion 3. However, the connecting member 5 does not have to have a plate shape as shown in FIG. 2, and does not necessarily have to be circular. The dish-shaped portion 4 can repeat the operation of moving forward and backward with respect to the container 1 while rotating by the driving force transmitted from the driving portion 3. The foodstuff stored in the container 1 is crushed by the bottom surface portion of the dish-shaped portion 4 that moves back and forth with respect to the container 1, and is further finely cut by the opening at the bottom surface portion of the dish-shaped portion 4.

FIG. 3 is a diagram conceptually showing the relationship between the dish-shaped portion 4 and the container 1. The container 1 is a dish-shaped container having a flat bottom surface. Further, the dish-shaped portion 4 has a flat bottom surface portion like the container 1, and a plurality of openings are provided in the bottom surface portion. As shown in FIG. 3, the inner bottom surface portion of the container 1 and the outer bottom surface portion of the dish-shaped portion 4 face each other in a state where the drive portion 3 to which the dish-shaped portion 4 is connected is assembled to the container 1. The foodstuff stored in the container 1 is crushed by the dish-shaped portion 4 moving in the direction of the arrow a. Further, as shown in FIG. 3, when the curvature of the outer peripheral portion of the dish-shaped portion 4 is substantially the same as the curvature of the inner peripheral portion of the container 1, the dish-shaped portion 4 is the inner peripheral side of the container 1 at the outer peripheral portion thereof. It is possible to crush the ingredients in.

FIG. 4 is a perspective view showing the appearance of the dish-shaped portion 4. As shown in FIG. 4, for example, the dish-shaped portion 4 is a circular dish-shaped member, and has a bottom surface portion 4a, an opening portion 4b, and a shaft portion 4c. A plurality of openings 4b are formed in the bottom surface portion 4a of the dish-shaped portion 4. For example, an opening 4b is formed at the center b of the bottom surface portion 4a of the dish-shaped portion 4, and a plurality of openings 4b are formed concentrically with the opening 4b. Further, the plurality of openings 4b are so long in the circumferential direction that they are provided outside the bottom surface portion 4a. In the dish-shaped portion 4, the opening area of the opening 4b is formed to be larger than the area of the bottom surface portion 4a other than the opening 4b (the area when the dish-shaped portion 4 is viewed from the axial direction). May be done.

The shaft portion 4c is formed by the branch-shaped portions 4c-1, 4c-2 and 4c-3 so as to be spaced from the center b of the bottom surface portion 4a of the dish-shaped portion 4 and coaxial with the center b. Connected to. With this structure, since the center b of the bottom surface portion 4a and the portion around it are not occupied by the shaft portion 4c, a plurality of openings 4b can be formed in this portion. As a result, even if the food material cut by the opening 4b moves onto the bottom surface 4a on the shaft portion 4c side, it falls to the bottom surface side of the container 1 through these openings 4b, so that the food material is not processed. It is prevented from remaining on the bottom surface portion 4a.

In FIG. 4, the dish-shaped portion 4 to which the shaft portion 4c is connected by the three branched portions 4c-1 to 4c-3 is shown, but the shaft portion 4c is spaced from the center b of the bottom surface portion 4a. As long as it is open and can be connected coaxially with the center b of the bottom surface portion 4a, the number of branch-shaped portions may be one or four or more.

Further, a wall portion 4d is formed at the outermost position on the bottom surface portion 4a of the dish-shaped portion 4. For example, as shown in FIG. 4, the wall portion 4d is formed at the opening peripheral portion of the elongated hole-shaped opening 4b located at the outermost position on the bottom surface portion 4a. Further, the wall portion 4d is inclined toward the center b side of the dish-shaped portion 4. The food strips that have moved to the bottom surface 4a on the shaft portion 4c side through the center b of the bottom surface portion 4a and the opening 4b of the portion around the bottom portion 4a further move outward on the bottom surface portion 4a. The wall portion 4d returns the small pieces of food that have moved outward on the bottom surface portion 4a to the center b side. The food strips returned to the center b side by the wall portion 4d fall to the container 1 side through the opening 4b formed around the center b. The foodstuff that has fallen to the container 1 side is finely processed again by the dish-shaped portion 4.

FIG. 5 is a block diagram showing a functional configuration of the drive unit 3. The drive unit 3 includes a motor 6 and a drive control unit 7. The motor 6 includes a drive mechanism for driving the dish-shaped portion 4, and is rotated by a drive command from the drive control unit 7. The drive mechanism converts the rotational force of the motor 6 into the rotational and linear driving forces of the dish-shaped portion 4, and is, for example, a drive mechanism using a ball screw. In this drive mechanism, the dish-shaped portion 4 is rotated around the shaft A by the rotational force transmitted from the motor 6, and further moved up and down along the shaft A.

The shaft portion 4c is connected to the drive mechanism at a position deviated from the center of the connecting member 5. The drive mechanism rotates the dish-shaped portion 4 around an axis A (rotational axis) passing through a position deviated from the center of the connecting member 5 as shown by arrow B, and further along the axis A as shown by arrow C. And move it up and down. In this way, the dish-shaped portion 4 moves back and forth with respect to the container 1 with a constant amount of movement while rotating around the axis A.

FIG. 6C is an axial plan view showing the rotation mode (3) of the dish-shaped portion 4. The mode of rotation of the dish-shaped portion 4 transitions from the mode (1) to the mode (2) to the mode (3). As shown by arrows in FIGS. 6A, 6B, and 6C, the connecting member 5 rotates around the shaft A by the rotational force of the motor 6, and the dish-shaped portion 4 also rotates around the shaft A accordingly. ..

FIG. 7 is an axial plan view showing the rotation locus of the dish-shaped portion 4. When the connecting member 5 rotates about the shaft A, the shaft portion 4c of the dish-shaped portion 4 rotates around the shaft A while drawing the locus D shown in FIG. At this time, the point located at the position farthest from the axis A on the circular outer circumference of the dish-shaped portion 4 draws the locus E shown in FIG. 7. That is, the region inside the locus E is the operating range of the dish-shaped portion 4.

If the shaft portion 4c rotates the dish-shaped portion 4 connected to the drive mechanism at the center of the connecting member 5 around the shaft A, the dish-shaped portion 4 rotates in the region designated by the reference numeral F in FIG. 7. Just do it. On the other hand, in the processing tool according to the first embodiment, since the shaft portion 4c of the dish-shaped portion 4 is deviated from the shaft A, the dish-shaped portion 4 is located in the inner region of the locus E having a larger area than the region F. Works. As a result, the operating range per rotation of the dish-shaped portion 4 is expanded, and the foodstuff can be processed evenly.

Although the case where the opening 4b pushes through the food has been shown so far, an edge may be provided in the opening 4b. FIG. 8 is an enlarged cross-sectional view showing an axial cross section of the opening 4b provided in the dish-shaped portion 4. An edge 4e protruding to the opposite side of the shaft portion 4c is formed at the opening peripheral edge portion of the opening portion 4b shown in FIG. For example, the burr generated at the peripheral edge of the opening when the opening 4b is formed by the punching process may be used as the edge 4e.

By controlling the motor 6, the drive control unit 7 moves the dish-shaped portion 4 toward the container 1 by a constant amount of movement. At this time, the opening 4b of the dish-shaped portion 4 is pressed against the food material stored in the container 1, and the food material is cut by the edge 4e of the peripheral edge portion of the opening. When the dish-shaped portion 4 is moved to the container 1 side by a constant movement amount, the drive control unit 7 controls the motor 6 to move the dish-shaped portion 4 in a direction away from the container 1 by a constant movement amount. By repeating these operations, the food material is cut into small pieces by the dish-shaped portion 4.

As described above, in the processing tool according to the first embodiment, the dish-shaped portion 4 rotates around the axis A passing through the position deviated from the center b of the dish-shaped portion 4, and the foodstuff to be processed is stored. Advances and retreats with respect to container 1. As a result, the foodstuff can be processed evenly and finely.

The processing tool according to the first embodiment includes a wall portion 4d provided at the outermost position on the bottom surface portion 4a of the dish-shaped portion 4. The food strips that have moved outward on the bottom surface portion 4a of the dish-shaped portion 4 are returned to the center b side of the dish-shaped portion 4 by the wall portion 4d. The food strips returned to the center b side of the dish-shaped portion 4 fall to the container 1 side through the opening 4b formed around the center b, so that the food strips remain in the dish-shaped portion 4. It is possible to prevent it from being processed.

In the processing tool according to the first embodiment, the dish-shaped portion 4 has a shaft portion 4c provided at a distance from the center b of the dish-shaped portion 4 and coaxially with the center b of the dish-shaped portion 4. The drive unit 3 rotates the dish-shaped portion 4 around an axis A passing through a position deviated from the shaft portion 4c. Since the center b of the bottom surface portion 4a and the portion around it are not occupied by the shaft portion 4c, a plurality of openings 4b can be formed in this portion.

Since the dish-shaped portion 4 of the processing tool according to the first embodiment is provided on the peripheral edge of the opening 4b and has an edge 4e protruding toward the container 1, the food can be cut into small pieces by the edge 4e. it can.

Embodiment 2.
FIG. 9 is a block diagram showing a functional configuration of the drive unit 3A included in the processing tool according to the second embodiment. The drive unit 3A includes a motor 6 and a drive control unit 7A. The motor 6 includes a drive mechanism for driving the dish-shaped portion 4, and rotates according to a drive command from the drive control unit 7A. The drive mechanism converts the rotational force of the motor 6 into the rotational force of the dish-shaped portion 4 and the linear motion in two directions. For example, the drive mechanism is a drive mechanism using a ball screw and a linear motion guide. In this drive mechanism, the dish-shaped portion 4 is rotated around the axis A by the rotational force transmitted from the motor 6, moved up and down along the axis A, and further moved in the direction orthogonal to the axis A.

The shaft portion 4c of the dish-shaped portion 4 is connected to the drive mechanism at a position deviated from the center of the connecting member 5, as in the first embodiment. The drive mechanism rotates the dish-shaped portion 4 around an axis A (rotational axis) passing through a position deviated from the center of the connecting member 5 as shown by arrow B, and moves up and down along the axis A as shown by arrow C. And further, as shown by the arrow G, it is moved in the direction orthogonal to the axis A. In this way, the dish-shaped portion 4 moves back and forth with respect to the container 1 with a constant amount of movement while rotating around the axis A, and moves in parallel with the container 1 with a constant amount of movement.

As described above, in the processing tool according to the second embodiment, the drive unit 3A rotates the dish-shaped portion 4 around the axis A, moves the dish-shaped portion 4 up and down along the axis A, and further is orthogonal to the axis A. Move in the direction. As a result, the operating range of the dish-shaped portion 4 in the container 1 becomes wider than that in the case where the range indicated by the arrows B and C is the operating range of the dish-shaped portion 4, and the foodstuff can be processed into small pieces quickly. Is possible.

Embodiment 3.
FIG. 10 is a block diagram showing a functional configuration of a drive unit 3B included in the processing tool according to the third embodiment. The drive unit 3B is a projecting portion protruding from the lid portion 2, and includes a motor 6, a drive control unit 7B, a sensor 8, a load determination unit 9, and a power supply control unit 10 as shown in FIG. The motor 6 has a drive mechanism for driving the output shaft.

When the motor 6 is rotated by a drive command from the drive control unit 7B, this rotational force is transmitted to the drive mechanism. The drive mechanism rotates the dish-shaped portion 4 around the shaft A by the rotational force transmitted from the motor 6, and further moves the dish-shaped portion 4 up and down along the shaft A. Further, the drive mechanism may move the dish-shaped portion 4 in the direction orthogonal to the axis A as in the second embodiment.

The drive control unit 7B was added to the protrusion by the first operation when the first operation of applying a load toward the container 1 was performed on the protrusion which is the drive unit 3B as shown by the arrow H. The driving speed of the dish-shaped portion 4 is changed according to the load. For example, the drive control unit 7B increases the drive speed of the dish-shaped portion 4 as the load applied to the protrusion increases, and the drive speed of the dish-shaped portion 4 increases as the load applied to the protrusion decreases. Will slow down. Since the degree of processing of the food material can be changed by the load applied to the protrusion in the first operation, the food material can be processed so that the desired texture remains.

The sensor 8 detects a signal corresponding to the load applied to the protrusion in the first operation. For example, as the sensor 8, a piezoelectric sensor that detects the load applied to the protruding portion can be used.
The load determination unit 9 determines the magnitude of the load applied to the protrusion in the first operation based on the detection signal detected by the sensor 8. The drive control unit 7B changes the drive speed of the dish-shaped portion 4 by controlling the rotation of the motor 6 according to the magnitude of the load determined by the load determination unit 9.

The power supply control unit 10 controls the supply of power to the drive unit 3B. For example, when the power is turned off by the power supply control unit 10, the drive unit 3B stops operating, and the dish-shaped unit 4 also stops operating. When the power is turned on by the power control unit 10, the drive unit 3B is in an operable state and is in a waiting state for the first operation.

Further, the power supply control unit 10 controls the supply of power to the drive unit 3B in response to the second operation. The second operation is different from the first operation, and is, for example, an operation of pressing the power button 3a in the direction of the arrow I. The power button 3a is provided at a position of the protruding portion away from the portion to which the load is applied in the first operation.

By turning on / off the power supply to the drive unit 3B in response to the second operation, it is possible to prevent the drive unit 3B from malfunctioning. For example, it is possible to prevent the drive unit 3B from being accidentally turned off during the first operation. Further, it is possible to prevent the drive unit 3B from being accidentally turned on when the dish-shaped portion 4 is not intended to be operated.

As described above, in the processing tool according to the third embodiment, when the first operation of applying a load toward the container 1 is performed on the protruding portion, the drive unit 3B is subjected to the first operation of the protruding portion. The driving speed of the dish-shaped portion 4 is changed according to the load applied to. Since the degree of processing of the food material can be changed by the load applied to the protruding portion in the first operation, the food material can be processed so that the desired texture remains.

In the processing tool according to the third embodiment, the power of the drive unit 3 is turned on and off by a second operation different from the first operation. As a result, it is possible to prevent a malfunction of the drive unit 3B.
