Is a handle.

Next, the operation will be described.

First, as shown in FIGS. 1A and 1B, when the fitting portion 26 of the container 4 is fitted into the mounting table portion 18 of the main body 3, the rotary shaft 17 is introduced into the tubular portion 27 and The container 4 is fixed to the main body 3 by engaging an engaging portion (not shown) and an engaged portion (not shown) provided on the fitting portion 26 and the mounting table portion 18, respectively.

Next, the knob portion 33 of the cutter 28 is clamped by the fingers 37 and the cutter shaft 31 is attached to the rotary shaft 17, whereby the rotation of the rotary shaft 17 can be transmitted to the cutter 28. At this time, the tip of finger 37 is a step
Since it is in contact with 38, when the cutter shaft 31 is attached to the rotary shaft 17, even if force is applied, the fingertip does not come into contact with the blade tip 28b of the cutter 28 in the center direction of the cutter 28, which is safe.

Next, the upper end opening of the container 4 is closed with the lid 7. At this time, since the closing cylinder lid 9 is not closed, the other of the switches 5 is off, so that the motor 2 does not rotate.

Next, if the workpiece is large, such as cabbage,
Cut into an appropriate size and put into the container 4 from the large charging port 8. At this time, since the large charging port 8 is larger than the conventional one, many workpieces can be charged at one time.

After the workpiece is input from the large input port 8, the second push rod 12 is inserted into the small input port 11 of the first push rod 10, and the engaging portion 49 of the first push rod 10 and the second push rod are inserted. Engage with 12 engaged parts 51,
The first push rod 10 and the second push rod 12 are integrally fixed, and the small charging port 11 is closed by the second push rod 12. In this way, the contents being cut do not overflow from the small input port 11 to the outside.

Next, when the large charging port 8 is closed by the charging cylinder lid 9, the switch pressing rib 40 provided on the charging cylinder lid 9 opens the hole 22 of the main body 3 through the mover 42 arranged on the lid body 7. Since it penetrates and presses the other movable terminal 20 of the switch 5, the switch 5 is turned on for the first time here. When the switch 5 is turned on, the motor 2 is rotationally driven, and this rotation is the motor shaft.
It is transmitted to the rotary shaft 17 via the pinion 15, the pinion 15, and the gear 16.

When the rotary shaft 17 rotates, the cutter 28 rotates and the workpiece in the container 4 is cut by the blade 28a. At this time, the workpiece on the upper surface of the cutter 28 may be wound around the knob portion 33 through the opening 34 provided in the diametrical wall portion 6a of the charging cylinder 6 formed in a semicircular shape. However, the first
As shown in FIGS. (A) and (b), the height h of the step portion 38 provided at the lower end portion of the knob portion 33 is determined by the lower end edge of the wall portion 6a of the charging cylinder 6 and the upper surface of the cutter 28. Since the gap 32 is formed to have almost the same height as the width g, the gap between the opening 34 and the step 38 is extremely narrow, and the work piece is not wound around the knob 33.

As the workpiece in the container 4 is cut, if the grip portion 50 is pressed, the push plate 46 descends and the workpiece is cut while being pressed. The cut work piece falls from the opening 30 provided in the cutter 28 to the lower portion of the container 4.

When the work piece is thin such as green onion or cucumber, the engagement between the engaging portion 49 and the engaged portion 51 provided on the first push rod 10 and the second push rod 12 is released. And then the small slot 11
Then, the second push rod 12 is pulled out to open the small insertion port 11.
Then, after the workpiece is input from the small input port 11, the second push rod 12 is inserted into the small input port 11 and pressed to the cutter.
Cut with 28 blade 28a.

After the cutting is completed, the switch 5 is turned off by opening the lid 7 together with the closing cylinder lid 9, so that the motor 2 is stopped. For the cutter 28, the knob 33 may be held between the fingers 37 and pulled out from the rotary shaft 17.

When not in use, as shown in FIG. 5, the cutter shaft 31 is placed in the upward direction and placed on the storage case 48, and the lid 7 is placed.
When closed by, the cutter 28 is stored in the lid 7 and the storage case 48 with the cutter shaft 31 being introduced into the opening 34.

[Advantages of the Invention] In the present invention, a disc-shaped cutter is provided with a blade on the upper surface, and a knob portion projecting upward at the center of rotation and having a stepped portion at the lower end is provided. The height of the stepped part and the gap between the lower end edge of the throwing cylinder and the upper surface of the cutter, which are located opposite to each other around the knob, are set to be approximately the same size, and the gap is located approximately in the center of the lid of the throwing cylinder. The wall formed in the diametrical direction of the throw-in cylinder has an opening in which the knob of the disk-shaped cutter faces, so that the workpiece on the upper surface of the cutter is wrapped around the knob. Since it is not flipped out of the throw-in cylinder, all the work pieces can be completely cut. Furthermore, when the cutter is removed from the rotation width after cooking, the knob is clamped with fingers and pulled out upward, but at this time, since the fingertips are in contact with the stepped portion that is higher than the cutting edge, The tip of the cutter blade will not scratch your fingertips.

Further, since an opening is formed in the wall portion which is located substantially in the center of the lid of the throwing barrel and is formed in the diameter direction of the throwing barrel, the tab portion of the disc-shaped cutter is opposed to the wall portion. When not in use, the cutter shaft is introduced into this opening, and the cutter can be stored by the lid and the storage case with the knob portion facing downward.
