After fitting the container lid 20 to the container 19, switch 2
When 8 is turned ON, the electric motor 1 is driven, and its rotation causes the small pulley 9, belt 11, large pulley 12,
The power is transmitted to the cutter 18 via the main shaft 13 and the connector 16, and the cutter 18 rotates to cut the object in the container 11.

フアン８により裏板２１に設けた排気孔２７より
外部に排出される。 Here, when the electric motor 1 is operated, the electric motor 1 generates heat due to the current supplied to the electric motor 1, which may lead to burnout. Therefore, it is necessary to cool the electric motor 1 while it is in operation. It is done as follows. When the electric motor 1 is operated, a fan 8 attached to the shaft 7 of the electric motor 1 rotates and sucks outside air through an intake hole 23 provided in the main body 4. The sucked air flows through an intake hole 24 provided on the top surface of the electric motor 1.
After entering the electric motor 1 and cooling the inside of the electric motor 1, it passes through an exhaust hole 25 provided on the lower surface of the electric motor 1,
The air is discharged to the outside through an exhaust hole 27 provided in the back plate 21 by the fan 8 .

み設けると、空気の排出量が少なくなるばかりで

なる。 Here, in order to increase the amount of exhaust from the back plate 21 without providing the cylindrical part 30, if the number of exhaust holes 27 in the back plate 21 located below the fan 8 is increased, Air is not exhausted from the exhaust hole 27 of the plate 21, but on the contrary, air is sucked into the main body 4 from the exhaust hole 27 (see FIG. 4). Therefore, not only does the exhaust efficiency deteriorate, but also significant air turbulence occurs, resulting in increased wind noise. Also,
If the exhaust hole 27 of the back plate 21 is provided only at the bottom of the outer diameter of the fan 8, not only will the amount of air discharged be reduced, but some air will not be exhausted and will be circulated between the back plate 21 and right below the fan 8. A vortex is generated and the wind noise becomes louder.

も小さくなる。 Therefore, as in the embodiment, a cylindrical portion 30 smaller than the outer diameter of the fan 8 is provided on the back plate 21 toward the fan 8 side, and an exhaust hole 2 is provided in the back plate 21 outside of this cylindrical portion 30.
7, even if the air discharged by the fan 8 tries to circulate to the lower center of the fan 8, it will hit the outer periphery of the cylindrical part 30, and the air will be removed from the exhaust hole 27 to the back plate 2.
1 (see Figure 3). Therefore, the exhaust efficiency is greatly improved. Further, since no eddy current or the like of air is generated between the fan 8 and the back plate 21, wind noise is also reduced.

効果を奏するものが得られるものである。 As described above, according to the present invention, by forming a cylindrical portion smaller than the outer diameter of the fan on the back plate of the main body from the back plate toward the fan, the exhaust efficiency is good, no vortex is generated, and wind noise is achieved. It is possible to obtain an excellent effect of having a small size.
