Field of the Invention The present invention relates to a technique for pinching a mustache, which is inserted into an outer cutter through a mesh of the outer cutter, from a corresponding position by rotation of the inner cutter in the outer cutter under the driving of a motor. The present invention relates to an inner blade structure of a rotary electric shaver for cutting.

Description of the Related Art As a so-called electric razor, for example, a movable inner blade provided at a plurality of positions on an upper surface of a disk-shaped rotary plate rotatable under the driving of a motor, and provided so as to cover the inner blade, 2. Description of the Related Art There is widely known a so-called rotary configuration that includes a fixed mesh-shaped fixed outer blade and cuts a beard by rotation of an inner blade with respect to the outer blade.

目を介して挿通されたヒゲを、外刃内における内刃の回
転のもとで、対応箇所から挟み切る構成となっている。A rotary electric razor of this type is used by pressing an outer blade against a skin to be shaved, and a beard inserted through a mesh of the outer blade is used to rotate the inner blade in the outer blade. , It is configured to be sandwiched from the corresponding location.

【発明が解決しようとする課題】公知の回転式電気かみ

となっている。そして、ヒゲは、肌に対して垂直に生え

り寝た状態で生えるものとされているため、ヒゲの傾斜
に対する逆方向に内刃の回転する場合であれば、外刃、
内刃間において、ヒゲは容易に切断できる。In known rotary electric razors, the inner blade is generally rotatable in only one direction. And since a beard rarely grows perpendicular to the skin, and usually grows in a state inclined to the skin, that is, in a lying state, the rotation of the inner blade in a direction opposite to the inclination of the beard. If you do, outer blade,
The beard can be easily cut between the inner blades.

ゲが外刃内で寝てしまい、外刃、内刃間でのヒゲの切断
が困難になるため、内刃の回転だけでは剃りきれない、
いわゆる剃り残しを生じる虞れがある。However, if the rotation direction of the inner blade is in the forward direction with respect to the direction in which the whiskers are formed, the whiskers lie inside the outer blade and it is difficult to cut the whiskers between the outer blade and the inner blade. , You can not shave just by rotating the inner blade,
There is a possibility that so-called unshaved residue may occur.

える向きの逆方向となるサイドではヒゲが剃りやすく、
順方向となるサイドではヒゲが剃り難くなるという現象
が生じるため、ヒゲ剃りの効率の低下、および速度の低
下が避けられない。That is, in a known rotary electric shaver that rotates the inner blade in one direction, the beard is easily shaved on the side where the rotation of the inner blade is in the opposite direction to the direction in which the beard grows.
Since a phenomenon occurs in which the beard is difficult to shave on the forward side, a reduction in the efficiency of the shave and a reduction in speed are inevitable.
【０００７】そして、ヒゲは、一方向に生えているとは
限らず、その方向は多様であるため、ヒゲの生える向き
によっては、公知の回転式電気かみそりが十分に対応し
きれなくなる虞れもある。The whiskers do not always grow in one direction, and the directions are various. Therefore, depending on the direction in which the whiskers grow, there is a possibility that the known rotary electric shaver may not be able to cope sufficiently. is there.

It is an object of the present invention to provide an inner blade structure of a rotary electric shaver that enables efficient shaving.

に抑制できる。By the way, in the embodiment of the present invention, both the inner peripheral inner blade 12-1 and the outer peripheral inner blade 12-2 are arranged at three places separated by 120 °. The number of inner cutters is not limited to the same number, and a different number of inner cutters and outer cutters may be arranged. Since the rotating plate outer peripheral portion 14-2 is located on the outer periphery of the rotating plate inner peripheral portion 14-1, a decrease in the number of rotations with respect to the rotating plate inner peripheral portion is inevitable. Therefore, if the outer peripheral inner blade 12-2 is additionally provided at the position indicated by the one-dot chain line in FIG. 3, a decrease in the number of rotations of the outer peripheral portion of the rotating plate can be compensated for by increasing the number of blades. As a result, the difference in the shaving efficiency between the blade 12-1 and the inner peripheral blade can be sufficiently suppressed.
