[0012] First, the rotary blade of the present invention will be described in detail with reference to the drawings. Figure 1(A) is a schematic diagram of one side (front side) of an embodiment of the rotary blade of the present invention, and Figure 1(B) is a schematic diagram of the back side of the rotary blade of this embodiment shown in Figure 1(A).

[0013] The rotary blade 1 of the present invention is a rotary blade that is detachably attached to the rotating shaft of a food processor, and when one side (front surface 21) is facing up, a first blade 3 that can cut is formed on the one side 21, and when the back side (back surface 22) opposite to the one side is facing up, a second blade 4 that can cut is formed on the top side.

[0014] The rotating blade 1 of the embodiment shown in Figure 1 has a mounting hole 23 at the center of the flat base 2 for mounting on the rotating shaft of the rotation unit of a food processor, and by inserting and fixing the rotating shaft into the mounting hole 23, the rotating blade 1 rotates horizontally around the rotating shaft. Furthermore, the rotating blade 1 can be easily attached and detached from the rotating shaft depending on the food processing method.

[0015] The rotary blade 1 of this embodiment is formed with a first blade 3 capable of cutting on the upper side with the front surface 21 facing upward, and a second blade 4 capable of cutting on the upper side with the back surface 22 facing upward, in the same rotation direction. Specifically, the blades are formed so that when rotating clockwise as viewed from above, the first blade 3 on the upper side can slice ingredients introduced thereto. When the blade is turned over, the second blade 4 is formed so that when rotating clockwise and facing upward, the second blade 4 can slice ingredients introduced thereto. In other words, the blade is configured so that the upper side can always process ingredients on either the front or back side of the rotary shaft rotating in a predetermined direction. Note that the second blade 4 in FIG. 1(A) and the first blade 3 in FIG. 1(B) show the back side, which cannot be cut.

[0016] The types of the first blade 3 on one side 21 and the second blade 4 on the back side 22 are not particularly limited, but it is preferable that the shapes of the first blade 3 and the second blade are different. Examples of the types of blades include a slicing blade, a shredding blade, a cutting blade, and a crushing blade.

[0017] 1(A) and 1(B), the combination of the first blades 3 and second blades 4 includes two wide first blades 3 for slicing and multiple second blades 4 for fine slicing, but the blade combination is not limited to this, and the first blades 3 can also be used as cutting blades and the second blades 4 as crushing blades. In this way, by providing various combinations of the first blades 3 and second blades 4, two types of cutting are possible by changing the front and back of a single rotating blade 1.

[0018] The first blades 3 and second blades 4 may be formed directly on the base portion 2 of the rotary blade 1, or the blades may be detachably attached by providing an attachment opening in the base portion 2. The number of first blades 3 and second blades 4 is not limited and can be determined appropriately depending on the design.

[0021] The lid 6 of the food processor 5 of this embodiment has an openable and closable opening 61 for inserting ingredients. A specific example of the opening 61 is an opening 61 that can be opened and closed by a cover plate that can slide horizontally left and right. The cover plate opens and closes depending on the processing method of the ingredients, and when closed, the opening 61 can be sealed.

[0022] The rotation unit 62 provided inside the lid 6 has a motor built in and is further equipped with a rotation shaft 63 directly connected to the motor. The motor can be rotated by a power supply device provided inside or outside the lid 6. When a power supply device is provided externally as an external power source, it is possible to use power supplied via an AC adapter that converts 100V AC for general household use into a specified DC current.

[0023] Furthermore, when a power supply device is built in as an internal power source, an internal battery such as a primary battery or a secondary battery can be used, and secondary batteries that can be charged and used continuously are particularly preferred. A particularly preferred secondary battery is a lithium-ion battery. Mobile batteries and non-contact power sources that use secondary batteries can also be used. Furthermore, both an external power source and an internal power source can be used as a power supply device. By providing an internal power source, the food processor 5 can be made cordless and easily portable.

[0024] The switch 65 for supplying power can be provided at any position on the lid portion 6 and is not particularly limited, but from the standpoint of operability, it is preferable to provide it at the top of the handle 64 provided on the lid portion 6, as in the embodiment shown in Figures 2 and 3.

[0025] A removably fixed storage cup 7 is provided at the bottom of the lid 6. The storage cup 7 can be sealed by joining with the lid 6, and food can be cut, crushed, sliced, and stored inside. The shape of the storage cup 7 can be determined appropriately depending on the type and shape of the rotary blade 1 of the present invention to be installed therein, and is not particularly limited. However, if the rotary blade 1 is equipped with a shaft, the shape is usually determined taking into account the length of the shaft. Furthermore, the storage cup 7 is preferably formed of a transparent material so that the processed food can be seen. Furthermore, the bottom 71 of the storage cup 7 is preferably openable or detachable, as shown in FIG. 4. By making the bottom 71 of the storage cup 7 openable, detachable, or removable, the bottom 71 can be removed as needed to directly serve the cut food on a dish.

[0026] The above describes the rotating blade of the present invention and the food processor using the same based on an embodiment, but the present invention is not limited to the above embodiment and various modifications are possible within the scope that does not deviate from the gist of the present invention.

[0027] For example, in the food processor 5 of the above embodiment, one rotating blade 1 of the present invention is attached to the rotating shaft 63 of the rotating unit 62, but multiple rotating blades 1 of the present invention can be attached at intervals, or the rotating blade 1 of the present invention can be used in combination with a conventional rotating blade that can slice, etc. on only one side.

[0028] The rotating blade of the present invention configured as described above allows different slicing on the front and back of a single blade, making it possible to perform various types of processing with a small number of slices.Furthermore, the food processor of the present invention configured as described above allows for simple and efficient preparation of ingredients for cooking and processing of ingredients, and allows for easy selection and switching of various types of processing.
