Patent JP-H03292912-A (JP)
Title: Cooking tool
Inventor: TAKAMA TOSHIKI
IPC: B26D3/26
Filed: 1990-04-11
Abstract: PURPOSE:To reduce irregular revolution even if the fitting condition of cutter blades varies a little and reduce noises and vibrations and further, stably keep the optimum cutting ability by forming the front edge of the cutter to be a coaxial arc with the inner wall of a vessel. CONSTITUTION:The front edge 12 of the lower cutter blade 8 forms an arc having the length (e) and defines a circle having a radius (a). The fitting condition of the blades varies due to the feeding condition and abrasion of a whetstone on fitting the cutter blades 8. Even if the whetstone is fed excessively, the shape of the cutter blade varies from the chain-lined part to the solid-lined part but the radius of the circle made by the front edge of the cutter can be kept to be in the state (a). In this way, even if the fitting condition of the cutter blade 8 varies, when it is within the arc (e), the radius of gyration of the cutter blade 8 does not vary. That is, the radius of gyration of the cutter blade 8 can keep the most efficient length (a) and reduces irregular revolution and further, the clearance between the vessel 4 and the front edge of the cutter blade does not varies either.
