DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooker in which a container having a cooking blade mounted thereon is mounted on a main body containing a driving motor, and the cooking blade is rotated by the motor.

[0002]

2. Description of the Related Art Conventionally, a cooker shown in FIG. 16 is known. In FIG. 16, reference numeral 1 denotes a main body having a built-in drive motor (not shown), and a container 3 is detachably mounted on an upper surface 2 of the main body 1. The main body 1 is provided with a drive shaft 4 rotatably driven by the drive motor, and the drive shaft 4 projects from the upper surface 2 and
Penetrates the container 3 through the bottom 5 of the container. A cooking blade 6 rotated by a drive shaft 4 is detachably provided in the container 3. By replacing the cooking blade 6, various kinds of cooking such as grated, shredded, and juice can be performed.

[0003] Reference numeral 7 denotes an operation lid for closing the upper opening of the container 4. The operation lid 7 has an operation part 7 a for covering an upper part of a protruding part 1 a formed integrally with the main body 1.
a is provided with an operation projection 7b that enters the operation hole 9 provided above the protrusion 1a. A switch S for driving the drive motor is provided in the protrusion 1a, and the switch S is turned on / off by an operation protrusion 7b.

That is, when the operation lid 7 is placed over the upper opening of the container 4 and pressed by hand from above, the operation projection 7b enters the operation hole 9 to turn on the switch S, and when the hand is released from the operation lid 7, the switch S Is turned off. When the switch S is turned on and the drive motor is driven, the cooking blade 6 rotates and cooks the material placed in the container 4.

[0005] The operation lid 7 is provided with an air hole 7c for communicating the inside of the container 4 with the outside air. This is to prevent the pressure inside the container 4 from increasing during cooking. In other words, when the pressure in the container is increased, there is a problem in that if the hand holding down the operation lid 7 from above is released during cooking, the operation lid 7 jumps out due to the pressure. Further, when cooking on juice or the like, there is a problem that the vertical movement of the material due to the rotation of the cooking blade is suppressed by the pressure, the stirring efficiency is reduced, and the cooking efficiency is reduced. This is to prevent these problems.

[0006]

However, in such a cooker, since the operation lid 7 is pressed from above by hand, there is a possibility that the air hole 7c may be closed by the hand. In particular, in a downsized cooker, since the area of the operation lid 7 is small, there is a problem that the air hole 7c is completely closed when the operation lid 7 is pressed from above with one hand.

If the friction between the operation lid 7 and the opening of the container 4 is large, the switch S remains on even if the hand holding the operation lid 7 is released. However, there is a problem that the cooking blade 6 keeps rotating.

The present invention has been made in view of the above-mentioned problems, and has as its object to prevent the air holes from being blocked and to prevent the cooking blade from continuing to rotate even when the hand is released. It is to provide a cooker.

[0009]
