In addition, 94.95 is one bus line 80 and both lines 80.8
This is an inductance and a capacitor for noise prevention connected between 1 and 1.

Next, the operation of the food processing machine configured as described above will be explained.

First, when chopping food such as vegetables or mixing food such as noodle flour with water in the food container 12 placed on the lower part of the drive unit case 1, please refer to Fig. 1 and 1. As shown in FIG. 3, a cutter 19 or kneading blade 20 suitable for food processing is fitted onto the fitting cylinder 11 at the upper end of the output shaft 8, and the lid 15 is placed on the opening 12b of the food container 12. When the lid 15 is rotated clockwise and held in a predetermined position, the first switch 32 is closed by the cam piece 38 provided on the outer periphery of the lid 15.

After that, select the push button 28 on the switch cover 21 to select the selection switch 23 a to 23 C suitable for food processing.
When the motor 6 is closed, the conduction angle of the thyristor 90 is controlled to rotate the motor 6 at a desired rotational speed, and the rotation is transmitted to the output shaft 8 via the drive pulley 7, timing bell 10, and driven pulley 9. Cutter 19 or kneading blade 2
0 is rotated.

Therefore, the food that has been placed in advance into the food container 12 or that has been placed through the cylindrical portion 15a of the lid 15 is
Processing is performed by the cutter 19 or the kneading blade 20.

During food processing using this cutter 19 or kneading blades 20,
Since the first switch 32 connected to the power supply circuit of the motor 6 is closed only when the lid 15 is positioned at a predetermined position as described above, the lid 15 is not attached. There is no risk that the cutter 19 or kneading blade 20 inside the food container 12 will be rotated in an exposed state in this state.
Can be used safely.

Next, using the noodle making unit, the kneading blade 20 is
When rolling the kneaded food such as noodle flour or cutting the rolled flat noodles, as shown in FIGS. 2 and 4 to 7, Lid 1
5 and place the noodle making unit case 39 on the opening 12b of the food container 12 and rotate it counterclockwise in the plane, the latch member 49 provided on the outer periphery of the unit case 39 will lock onto the food container 12. The unit case 39 is engaged with a member 17 around the opening 12b of the container 12 to be latched and held in a predetermined position.

At the same time, a wide space is formed below the front edge of the unit case 39.

When the noodle-making unit case 39 is installed, the connection plate 52 at the lower end of the input shaft 50 protrudes from the underside of the noodle-making unit case 39 and the kneading blade 20 installed on the output shaft 8 on the drive unit case 1 side.
The connecting protrusion 20a at the upper end engages with the input shaft 50.
is connected to the output shaft 8 through the opening 12b of the food container 12.

Further, in the attached state of the noodle making unit case 39,
The first switch 82 is closed by the cam piece 76 provided on its outer surface, and the second switch 33 is opened.

After that, press the low speed setting push button 2 on the switch cover 21.
8 to close the low-speed selection switch 23a, the remoter 6 is rotated at a low speed by the conduction angle control of the thyristor 90, and the output shaft 8 and input shaft 50 are rotated integrally.

Thereby, the worm 53 . The rolling rollers 61 and 62 are rotated through the worm wheel 55 and the transmission spur gears 56, 58, and 59, and the noodle cutting rollers 69 and 62 are rotated through the transmission spur gear 58 and the clutch 71.
70 is rotated.

Therefore, if a dough food such as noodle flour is put into the rolling gap between the rolling rollers 61 and 62 from the input port 64, the food will be rolled by the rolling rollers 61 and 62 and fall downward from the take-out port 65. , you can make flat noodle wrappers, etc., and you can also use the noodle cutting reroller 6
If the flat noodles are fed into the cutting gap between both rollers from the input roller 3 on the left or right side of the noodle cutting rollers 69 and 70, the flat noodles are cut into a predetermined width by the noodle cutting rollers 69 and 70, and then passed downward from the take-out roller 4. You can make udon, soba, etc.

Furthermore, when this noodle making unit is used, as is clear from FIGS. 6 and 7, there is a wide space below the front edge of the unit case 39, so a container or the like is placed in that space and the outlet is opened. Foods such as flat noodles or udon noodles falling from 65.74 can be easily received.

During food processing by this noodle making unit, the first switch 32 connected to the power supply circuit of the motor 6 is closed only when the unit case 39 is positioned at a predetermined position as described above. Therefore, there is no risk that the output shaft 8 will be rotated when the unit case 39 is not placed at a predetermined position, and it can be used safely.

In addition, since the second switch 33 connected to the control circuit of the motor 6 is opened when the unit case 39 is positioned at a predetermined position, the second switch 33 connected to the control circuit of the motor 6 is opened. Selection switch 23 b, 23
Even if C is closed, the motor 6 is not rotated, and the motor 6 is rotated at a low speed only when the low speed selection switch 23a is closed, and the rolling roller 61.62 and the noodle cutting reroller 69.70 are rotated at a low speed. Since it is always rotated at an appropriate speed, there is no risk of delay in feeding the food to both rollers, and the rolling work of the dough food and the noodle cutting work can be performed accurately.

Note that this invention is not limited to the configurations of the embodiments, and the configuration of each part can be arbitrarily changed without departing from the spirit of this invention.

As detailed above, when using an attachment with a built-in rolling roller or noodle cutting reroller, this invention replaces the lid that covers the top opening of a food container with a built-in cutter or kneading blade, and allows the attachment to be connected to the drive unit. Since it is configured to be connected to the lower part through the food container, even if the attachment itself is small, a large space can be secured below the roller, and this space can be used for rolling or noodle cutting. The stored food can be received in a container or the like and easily taken out.

In addition, this invention has an extremely simple structure, with the simple operation of simply attaching the attachment when using the attachment, and the switch provided on the high part of the drive unit I is opened directly by the cam piece. in spite of,
Due to incorrect operation of a selection switch that controls the rotational speed of the motor, selecting a rotational speed that is not suitable for driving an attachment connected in series with the switch,
It is possible to reliably prevent the rollers in the attachment from being rotated at inappropriate speeds such as high speeds, and the rollers are always rotated at the appropriate selected speed, allowing for accurate rolling of dough foods and noodle cutting operations. can be done.
