Next, the operation of the cooking device of the above embodiment will be described.

First, the material to be cooked is put in the container 40 and the opening of the container 40 is closed with the lid 60. After this, this container 4
The fitting portion 46, which is the fitted tubular portion of No. 0, is loosely inserted into the large-diameter tubular portion 22b of the mounting portion 22, which is the container fitting tubular portion of the main body 20.

As a result, the fitting portion 46 is guided by the inclined step portion G and fitted into the small-diameter cylindrical portion 22c of the mounting portion 22, while the plurality of ribs 47 (locked projections) provided on the fitting portion 46 are provided. )
Are engaged with the locking projections T provided on the large-diameter cylindrical portion 22b of the mounting portion 22, the container 40 is non-rotatably locked to the main body 20, and the container 40 rotates in the circumferential direction. Regulate
Will be.

At this time, the rib 48 provided on the fitting portion 46 of the container 40 comes into contact with the mounting surface 22a at the upper end of the mounting portion 22,
A gap D, which is an exhaust air outlet, is formed between the bottom surface 45 of the container 40 and the mounting surface 22a.

Next, the operation case 70 is put on the lid 60 and the projection 50, and the operation projection 73 is inserted into the operation hole 51. In this state, when the operation case 70 is pressed from above by hand, the operation projection 73 is opposed to the spring 53 by the operation rod 52.
Is moved downward. As a result, the switch 54 is turned on and the motor 21 is driven. By driving the motor 21, the rotating shaft 43 and the cutter 44 are driven together with the driving shaft 33.
Rotate, and the material is crushed and cooked by the rotation of the cutter 44.

On the other hand, the rotation of the drive shaft 33 rotates the blower fan 35 together with the coupling 34, and the rotation of the blower fan 35 sucks air from the vent hole 25 formed in the bottom 23 of the main body 20, so that the air flows in the direction of the arrow. It flows to. The motor 21 is cooled by the flow of the air.

Most of the air (heated air) that has cooled the motor 21 is blown in the radial direction by the cooling fan 35 and then formed in the small-diameter cylindrical portion 22c and the large-diameter cylindrical portion 22b of the mounting portion 22. After passing through the air passage H, the air flows from the air passage H to the outside through a gap D formed between the bottom surface 45 of the container 20 and the mounting surface 22a. After a part of the cooling air is blown in the radial direction by the cooling fan 35, the cooling air is discharged from the passage 29 to the outside through the discharge hole 26 provided in the bottom portion 23 of the main body 20.

The cooling air blocking wall 90 as shown by the broken line in FIG. 3 is located between the ventilation hole 25 and the discharge hole 26 and protrudes downward from the bottom 23 so that the motor 21 can be moved. The cooling air heated by cooling may be prevented from being sucked in again from the ventilation hole 25.
