2. Description of the Related Art A rotating body provided with a cutter is provided in a container having an upper opening, and a main body provided with an electric motor for rotating the rotating body is mounted on an opening of the container to rotate the rotating body. 2. Description of the Related Art A cooker that cuts and stirs an object to be cooked in a container to cook is widely used in general households and the like.

As shown in FIG. 2, a lower end of a conventional rotary member provided in a container of this type of cooker is supported by a bearing hole provided at a lower end of a cutter base 111 of a rotary member 110. 112 is fitted to a support shaft 103 integrally attached to the bottom wall 102 of the container 101 of the cooking device 100, and the upper end is a rotating shaft 11 provided on the cutter table 111.
The coupling 114 is attached to a coupling 122 provided to be exposed outside from the bottom wall 121 of the cooker main body 120 and attached to the distal end of the cooking device 120.

[0004] The coupling 122 is connected to an electric motor 130 mounted inside the cooker main body 120.
Is driven to rotate. In other words, the belt 136 hangs on the driven pulley 135 attached to the same shaft 134 as the bevel gear 133 and the driving pulley 132 attached to the output shaft 131 of the electric motor 130, and is attached to the same shaft 137 as the coupling 114. By engaging the bevel gear 138 with the bevel gear 133, the rotational force of the electric motor 130 is transmitted to the coupled
, And the coupled coupling 114 is rotationally driven. Note that a cutter 115 is attached to the cutter table 111.

When cooking a desired dish,
When the cooking material, that is, the object to be cooked is put in the container 101 and the electric motor 130 is driven, the rotating body 110 rotates,
The food is cut and stirred by the cutter 115 and cooked.

[0006] When cooking various dishes, the cutter 115, that is, the rotating body 1 may be used depending on the dish.
In some cases, the 10 must be rotated at high speed. However, when the rotating body 110 is rotated at a high speed, the supporting shaft 103 supporting the rotating body 110 is
02, the bearing hole 112 provided in the cutter table 111 and the support shaft 103 are rubbed at a high speed.
2 wears and deteriorates.

[0007] Therefore, the above-mentioned conventional cooking device has to be set at a low rotation speed, which is not always satisfactory in terms of cutting and stirring performance. That is,
Cooking that requires cutting or stirring at high speed cannot be performed, and if such cooking is performed, there is a possibility that good cooking may not always be performed.

[0008]

As described above, this type of conventional cooking device 100 has a high speed because the support shaft 103 for supporting the rotating body 110 is fixedly attached to the bottom wall of the container 101. Since it cannot be rotated, it is not always satisfactory in terms of cutting and stirring performance, and cooking that requires cutting or stirring at high speed cannot be performed, and if such a dish is cooked, good cooking is not necessarily performed. is there.

The engagement hole 56 is fitted to the fitting shaft 30 provided in the bottom wall region 24 which is the bottom wall of the container 1. At this time, the engaging portion 57 and the engaged portion 31 are engaged with each other.

Then, after the desired cooking material, that is, the object to be cooked is put in the container 1, the upper opening 11 is closed with the lid 40. At this time, the convex coupling 52 is
Through the through hole 46.

Next, the main body 60 is placed on the lid 40. When this mounting, the convex coupling 52
Is located in the cylindrical wall 47 through the through hole 46, so that when the main body 60 is placed on the lid 40, the concave coupling 86 is located in the cylindrical wall 47. It automatically engages with the coupling 52.

When the operation button 91 is operated, the power switch 95 is turned on, and the electric motor 80 is driven.

The engaging portion 57 of the rotating body 50 is engaged with the engaged portion 31 of the fitting shaft 30, and the fitting shaft 30 is rotatably supported by the bearing 28. Therefore, the fitting shaft 30 rotates integrally with the rotating body 50. Therefore, even if the rotating body 50 rotates at high speed, there is no friction between the fitting shaft 30 and the fitting hole 56. Therefore, wear of the fitting hole 56 or the like due to the friction or deterioration of the cutter table due to abrasion heat. And the like can be prevented.

The object to be cooked is forcibly rotated while being cut in the container 1 by the cutter 58 which is rotated by the rotation of the rotating body 50 during cooking. Although there is no problem in the upper part of the cutter 58 due to the wide space, the cutter 58
Is difficult to flow due to the small space in the lower part, but the cutter stand 55 and the holding body 27 to which the bearing 28 of the fitting shaft 30 is attached are set to have substantially the same diameter. Since a space portion having a smooth periphery, that is, a flow path of the object to be cooked is formed between the cutter table 55, that is, the lower portion of the rotating body 50, the periphery of the holder 27, and the bottle portion 10, that is, the peripheral wall of the container 1. The object to be cut or agitated flows smoothly, does not stay in the lower part, and the dish is cooked efficiently and well.

The structure of the rotating body 50 is not limited to the shape shown in the above embodiment, but may be any shape as long as it can rotate in the container 1. That is, it can be freely changed so as to conform to the shape of the container.

Further, the shape of the cutter and the like can be adapted to the dish to be cooked.

In the above embodiment, the container 1
Although the lid 40 is provided in the upper opening 11 of this embodiment, the lid 40 may be omitted, and the main body 60 may be directly placed on the container 1 so as to correspond to the upper opening 11.

Further, in the above embodiment, the engaging portion 57 provided on the cutter table and the engaged portion 31 provided on the fitting shaft 30 are each formed into a D-shaped engaging hole and a D-shaped. However, the shaft is formed with a ridge as an engaged portion on the outer periphery of the fitting shaft 30, and the cutter table 55 is formed.
Alternatively, a projection as an engaging portion that engages with the ridge may be formed, and the ridge and the projection may form an engaged portion and an engaging portion.
