FIG. 1 is a perspective view showing the appearance of a processing tool according to Embodiment 1. FIG. FIG. 2 is an exploded perspective view showing the configuration of the processing tool according to Embodiment 1. FIG. The processing tool according to Embodiment 1 is, as shown in FIG. 1, provided with a container 1, a lid portion 2 and a driving portion 3, and is a tool for chopping and smashing foodstuffs into small pieces. The container 1 is a dish-shaped container. A food material to be processed is stored in the container 1 . The lid portion 2 is detachably attached to the container 1 so that the food material being processed does not leak out of the container 1 . The driving unit 3 generates a driving force used for processing foodstuffs. For example, as shown in FIG. 1, the driving portion 3 is a protruding portion that protrudes from the lid portion 2 .

It is assumed that the object to be processed by the processing tool according to the first embodiment is not a hard food material such as raw vegetables, but a relatively soft cooked food material. For example, the processing tool according to Embodiment 1 is used when making baby food or nursing care food from normal meals. Baby food or nursing care food can be made by processing ingredients that have been cooked as normal meals so that the texture remains as if chopped with a kitchen knife or mashed with a fork. However, the task of finely chopping ingredients with a kitchen knife or fork is troublesome. On the other hand, the processing tool according to the first embodiment can finely process foodstuffs more easily than kitchen knives or forks.

The processing tool according to Embodiment 1 includes a dish-shaped portion 4 and a connecting member 5, as shown in FIG. The dish-shaped part 4 is a dish-shaped metal member having one or more openings penetrating through the bottom surface and having a shaft coaxial with the center of the bottom surface. 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 may not be plate-shaped as shown in FIG. 2, and may not necessarily be circular. The dish-shaped portion 4 can repeat the movement of advancing and retreating with respect to the container 1 while being rotated by the driving force transmitted from the driving portion 3 . The food stored in the container 1 is crushed by the bottom surface of the dish-shaped portion 4 that advances and retreats with respect to the container 1, and is cut finely by openings in the bottom surface of the dish-shaped portion 4. - 特許庁

FIG. 3 is a diagram conceptually showing the relationship between the dish-shaped portion 4 and the container 1. As shown in FIG. A container 1 is a dish-shaped container having a flat bottom portion. Further, the dish-shaped part 4 has a flat bottom part, like the container 1, and a plurality of openings are provided in this bottom part. 3, the inner bottom surface of the container 1 and the outer bottom surface of the dish-shaped portion 4 face each other when the driving portion 3 to which the dish-shaped portion 4 is connected is assembled to the container 1. As shown in FIG. The foodstuffs stored in the container 1 are crushed by the dish-shaped part 4 which moves 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 outer peripheral portion of the dish-shaped portion 4 is curved toward the inner peripheral side of the container 1 . It is possible to crush the ingredients in

The dish-shaped portion 4 is a circular dish-shaped member, for example, as shown in FIG. 4, and has a bottom portion 4a, an opening portion 4b, and a shaft portion 4c. A plurality of openings 4b are formed in the bottom portion 4a of the dish-shaped portion 4. As shown in FIG. For example, an opening 4b is formed at the center b of the bottom portion 4a of the dish-shaped portion 4, and a plurality of openings 4b are formed concentrically with this opening 4b. Furthermore, the plurality of openings 4b are elongated in the circumferential direction so as to extend outward from the bottom surface 4a. In addition, in the dish-shaped portion 4, the opening area of the opening 4b is formed to be larger than the area of the portion other than the opening 4b in the bottom portion 4a (the area when the dish-shaped portion 4 is viewed from the axial direction). may be

Axle 4c is connected to dish 4 by branches 4c-1, 4c-2 and 4c-3 so as to be spaced from and coaxial with center b of bottom surface 4a of dish 4. connected to With this structure, the shaft portion 4c does not occupy the center b of the bottom surface portion 4a and its peripheral portion, so that a plurality of openings 4b can be formed in this portion. As a result, even if the food material cut by the openings 4b moves onto the bottom surface part 4a on the side of the shaft part 4c, 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.

Although FIG. 4 shows the dish-shaped portion 4 to which the shaft portion 4c is connected by three branch-shaped portions 4c-1 to 4c-3, the shaft portion 4c is spaced apart from the center b of the bottom portion 4a. The number of branch-like portions may be one or four or more as long as they can be connected coaxially to the center b of the bottom portion 4a with a space therebetween.

A wall portion 4d is formed at the outermost position of the bottom portion 4a of the dish-shaped portion 4. As shown in FIG. For example, as shown in FIG. 4, the wall portion 4d is formed along the periphery of the elongated hole-shaped opening 4b located at the outermost position in the bottom portion 4a. Furthermore, the wall portion 4d is inclined toward the center b of the dish-shaped portion 4. As shown in FIG. After passing through the center b of the bottom portion 4a and the openings 4b around it, the small pieces of the food material move onto the bottom portion 4a on the side of the shaft portion 4c, and then move further outward on the bottom portion 4a. The wall portion 4d returns the small pieces of food material that have moved outward on the bottom portion 4a toward the center b. The small pieces of food returned to the center b side by the wall part 4d fall to the container 1 side through the opening part 4b formed around the center b. The food that has fallen on the side of the container 1 is finely processed again by the dish-shaped part 4. - 特許庁

The motor 6 has a drive mechanism for driving the dish-shaped portion 4 and rotates according to a drive command from the drive control portion 7 . The drive mechanism converts the rotational force of the motor 6 into a drive force for rotation and linear motion of the dish-shaped portion 4, and is, for example, a drive mechanism using a ball screw. This drive mechanism rotates the dish-shaped portion 4 around the axis A and moves it up and down along the axis A by means of the rotational force transmitted from the motor 6 .

The shaft portion 4 c is connected to the driving mechanism at a position shifted 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 off the center of the connecting member 5 as indicated by arrow B, and further rotates along the axis A as indicated by arrow C. to move it up or down. In this manner, the dish-shaped portion 4 advances and retreats with respect to the container 1 by a constant amount of movement while rotating about the axis A. As shown in FIG.

FIG. 7 is an axial plan view showing the locus of rotation of the dish-shaped portion 4. As shown in FIG. When the connecting member 5 rotates around the axis A, the shaft portion 4c of the dish-shaped portion 4 rotates around the axis A while drawing a trajectory D shown in FIG. At this time, the point furthest from the axis A on the circular outer circumference of the dish-shaped portion 4 draws a trajectory E shown in FIG. That is, the area inside the locus E is the movement range of the dish-shaped portion 4 .

If the shaft portion 4c rotates the disk-shaped portion 4 connected to the driving mechanism at the center of the connecting member 5 around the axis A, the disk-shaped portion 4 rotates in the region denoted by reference numeral F in FIG. Just do it. On the other hand, in the processing tool according to Embodiment 1, since the shaft portion 4c of the dish-shaped portion 4 is displaced from the axis A, the dish-shaped portion 4 is moved within the region inside the trajectory E having a wider area than the region F. works. As a result, the range of movement per rotation of the dish-shaped portion 4 is widened, and the food can be processed evenly.

Although the case where the opening 4b pushes through the foodstuff 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. As shown in FIG. An edge 4e projecting to the side opposite to the shaft portion 4c is formed at the opening peripheral portion of the opening portion 4b shown in FIG. For example, when the opening 4b is formed by punching, a burr generated on the periphery of the opening may be used as the edge 4e.

The drive control unit 7 controls the motor 6 to move 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 contained in the container 1, and the food is cut by the edge 4e of the opening peripheral portion. When the dish-shaped portion 4 is moved toward the container 1 by a constant amount, the drive control section 7 controls the motor 6 to move the dish-shaped portion 4 away from the container 1 by a constant amount. By repeating these operations, the dish-shaped portion 4 cuts the food into small pieces.

Advances and retreats with respect to the container 1. As a result, the food can be finely processed without unevenness.

The processing tool according to Embodiment 1 includes a wall portion 4d provided at the outermost position on the bottom portion 4a of the dish-shaped portion 4. As shown in FIG. Small pieces of food material 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 small pieces of food returned to the side of the center b of the dish-shaped portion 4 fall to the side of the container 1 through the opening 4b formed around the center b. You can prevent it from being processed.

In the processing tool according to Embodiment 1, the dish-shaped portion 4 has a shaft portion 4c spaced apart from the center b of the dish-shaped portion 4 and coaxial with the center b of the dish-shaped portion 4 . The driving portion 3 rotates the dish-shaped portion 4 around an axis A passing through a position shifted from the shaft portion 4c. Since the center b of the bottom surface portion 4a and its peripheral portion are not occupied by the shaft portion 4c, a plurality of openings 4b can be formed in this portion.

FIG. 9 is a block diagram showing the functional configuration of a drive section 3A provided in the processing tool according to Embodiment 2. As shown in FIG. The drive section 3A includes a motor 6 and a drive control section 7A. The motor 6 has a drive mechanism for driving the dish-shaped portion 4, and rotates according to a drive command from the drive control portion 7A. The drive mechanism converts the rotational force of the motor 6 into a drive force for rotation of the dish-shaped portion 4 and linear motion in two directions, and is, for example, a drive mechanism using a ball screw and a linear motion guide. This drive mechanism rotates the dish-shaped portion 4 around the axis A, moves it up and down along the axis A, and further moves it in a direction perpendicular to the axis A by the torque transmitted from the motor 6 .

The shaft portion 4c of the dish-shaped portion 4 is connected to the driving mechanism at a position shifted 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 displaced from the center of the connecting member 5 as indicated by an arrow B, and vertically along the axis A as indicated by an arrow C. , and in a direction orthogonal to axis A as indicated by arrow G.

Embodiment 3.
FIG. 10 is a block diagram showing the functional configuration of a driving section 3B included in the processing tool according to Embodiment 3. As shown in FIG. The drive unit 3B is a protrusion projecting from the lid unit 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 that drives the output shaft.

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

When a first operation of applying a load toward the container 1 as indicated by the arrow H is performed on the protruding portion of the driving portion 3B, the drive control portion 7B applies a load to the protruding portion by the first operation. The driving speed of the dish-shaped portion 4 is changed according to the load. For example, the drive control unit 7B increases the driving speed of the dish-shaped portion 4 as the load applied to the projecting portion increases, and increases the driving speed of the dish-shaped portion 4 as the load applied to the projecting portion decreases. slow down. Since the degree to which the food is processed can be changed by the load applied to the protruding portion in the first operation, it is possible to process the food 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 protrusion can be used.
Based on the detection signal detected by the sensor 8, the load determination section 9 determines the magnitude of the load applied to the protrusion in the first operation. The drive control section 7B changes the drive speed of the dish-shaped section 4 by controlling the rotation of the motor 6 in accordance with the magnitude of the load determined by the load determination section 9 .

The power control unit 10 controls power supply to the drive unit 3B. For example, when the power is turned off by the power control unit 10, the drive unit 3B stops operating, and the dish-shaped unit 4 also stops operating. When the power control unit 10 turns on the power, the driving unit 3B becomes operable and waits for the first operation.

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

By turning on and off the power supply to the drive unit 3B in response to the second operation, malfunction of the drive unit 3B can be prevented. For example, it is possible to prevent the drive unit 3B from being accidentally turned off during the first operation. In addition, it is possible to prevent the drive unit 3B from being erroneously turned on when there is no intention to operate the dish-shaped portion 4. FIG.

As described above, in the processing tool according to Embodiment 3, when the first operation of applying a load to the projecting portion toward the container 1 is performed, the driving portion 3B moves the projecting portion through the first operation. The drive speed of the dish-shaped portion 4 is changed according to the load applied to the . 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 Embodiment 3, the drive unit 3 is turned on and off by a second operation different from the first operation. As a result, malfunction of the driving section 3B can be prevented.

It should be noted that the present invention is not limited to the above-described embodiments, and within the scope of the present invention, each of the embodiments can be freely combined, or each arbitrary component of the embodiments can be modified or embodied. It is possible to omit any component in each of
