Description

[Detailed explanation of the invention] (a) Industrial application field This invention can be used for whipping eggs and fresh cream, stirring for making ingredients such as mayonnaise and pound cake, and cutting meat, vegetables, etc. This invention relates to a cooking machine equipped with a rotary blade that rotates and revolves around its axis.

(b) Prior art In cooking machines equipped with rotary blades that perform this type of rotation and revolution, for example, those equipped with stirring blades for eggs, fresh cream, etc. It was common for the sun gear to be integrally attached to the central boss of the container.

Therefore, when the attachment including the stirring blade is removed, the sun gear remains at the opening of the container, making it difficult to take out the material and clean the inside of the container.

(c) Purpose of the invention This invention was made in consideration of these circumstances, and one of its main purposes is to effectively perform cooking operations such as whisking eggs and cutting meat and vegetables. To provide a cooking machine which allows easy loading and unloading of ingredients before and after operation, facilitates cleaning of attachments including the inside of a container and stirring blades, and allows diversification of replaceable attachments. There is a particular thing.

(d) Structure of the invention This invention consists of a main body with a built-in electric motor, a cooking vessel attached to the main body, a drive shaft that receives rotational power from the electric motor and passes through the central boss of the cooking vessel, and this drive shaft. and an attachment that is attached to the central boss, and this attachment is removably connected to the drive shaft and receives rotational power from the drive shaft, and an arm shaft that is slidable and rotatable relative to the arm shaft. A cooking machine comprising a sun gear that is fixedly supported and non-rotatably engaged with a central boss, a planetary gear that is rotatably supported on the shaft end of the arm shaft, and a stirring blade that is fixed to the planetary gear. It is.

(e) Embodiments This invention will be described in detail below based on the embodiments shown in FIGS. 1 to 4 a to d. Note that this invention is not limited to this.

The main body 1 of the cooking machine has a built-in electric motor 2.
A drive shaft 3 protruding from the top surface is rotationally driven by a rotational force decelerated from an electric motor 2 via a belt 4 and a gear group 5. The cooking container (hopper) 6 attached to the main body 1 is composed of an integral container made of synthetic resin, which includes a central boss 6a that covers (passes through) the drive shaft 3, an outer peripheral wall 6b, and a bottom surface 6c. A revolution arm shaft 7 is connected to the drive shaft 3 so that torque (rotational force) can be transmitted thereto. That is, a hole of the arm shaft 7 having an oval cross-sectional shape and a fitting portion of the drive shaft 3 are provided as a pair, and the arm shaft 7 is coaxially fitted into the drive shaft 3.

A sun gear (fixed large gear) 8 is secured to the outer periphery of the arm shaft 7 by a retaining ring 9 in the axial direction and is allowed to rotate relative to the arm shaft 7. The inner circumferential surface of the downwardly protruding boss portion 8a and the outer circumferential surface of the central boss 6a of the cooking container 6 are fitted in a fluid-tight manner. In addition, in this fitting, contrary to the above, the outer periphery of the boss portion projecting downward may be made to correspond to the inner periphery of the central boss.

Furthermore, the protrusion 8b on the sun gear 8 side and the protrusion 6d provided at the tip of the central boss 6a are engaged, and the sun gear 8 is non-rotatably fitted to the central boss 6a.

A planetary gear 10 that meshes with the sun gear 8 is rotatably supported on the shaft end 7a of the arm shaft 7, and this planetary gear 10 is formed into a cage shape by a pair or multiple linear blades 11. A stirring blade (beater) 12 is fixed.

In addition, the arm shaft 7 is provided at the center of the upper end surface of the arm shaft 7.
In order to stabilize the cooking container 6 during rotation, that is, to prevent tilting and vibration, a through hole 7b is formed in the lid 15 equipped with the charging cylinder 14 which is fitted into the upper opening of the cooking container 6 by the locking part 13. It is pivotally supported by a steady rest shaft 16. The locking part 13 has a peripheral edge of the lid 15 hanging down inside the container 6 as shown in the figure, and clamps an ear part 6e arranged at the opening edge of the upper end surface of the container 6 from above and below. In addition, 17 is a switch for cooking operation.

Thus, in the cooking machine, the sun gear 8 as an attachment can be removed from the central boss 6a, making it easy to take out food, wash it, etc. In addition, the sun gear 8 is not left on the central boss 6a of the cooking vessel 6, and therefore, in setting other attachments, a sun gear with different specifications from the sun gear 8 can be used. Wings can be applied.

(f) Effects of the invention In this invention, the sun gear is connected to the arm shaft and can be removed from the central boss as an attachment, making it easier to take out and wash food, and other attachments can be attached to the sun gear. Since the specifications can be selected arbitrarily, it is possible to diversify the cooking contents.
