Kitchen knife sharpener

Abstract

The invention discloses a kitchen knife sharpener comprising a frame, a drive motor and a control system. A knife rest and a grinder device are disposed on the frame. The knife rest comprises a knife rest base and a knife clamping part. The knife rest base comprises a horizontal base plate which is manually pushed and pulled to move longitudinally back and forth on the frame. The knife clamping part comprises a horizontal knife-mounting transverse arm and a vertical connecting arm. The vertical connecting arm is connected to a vertical connecting plate of the knife rest base and driven to rotate by a rotating motor. The grinder device is arranged between the horizontal base plate and the horizontal tool-mounting transverse arm. The knife clamping part forms two grinding positions, having an angle larger than 120 degrees and smaller than 180 degrees, on the knife rest base; when a knife is at one optional grinding position, the central plane of the knife and the upper plane of a grinder have an included angle larger than 0 degree. The kitchen knife sharpener has the advantages that knife grinding loss is low, environmental pollution is zero, knife sharpening effect is high, and utilization rate of the grinder is high.

Description

technical field [0001] The patent of the present invention relates to a kitchen facility, in particular to a knife grinder for grinding kitchen knives. Background technique [0002] The main variety of kitchen knives is kitchen knives. There are usually two grinding methods for existing kitchen knives. One is to use a whetstone and the sharpener directly moves the knife on the whetstone by hand. This grinding method is inefficient, labor-intensive, and the grinding quality Unevenness, that is, the sharpness of the tool after grinding, the service life after grinding once, and the loss of the tool per grinding are all affected by the skill level of the sharpener. The second is to use a knife grinder composed of a rotating grinding wheel for grinding, and its tool feeding method includes manual feeding of a manual hand-held tool and mechanical feeding by a feeding mechanism. However, existing grinders or knife grinders all use rotating emery wheels as grinding tools for tool...

AI Technical Summary

Problems solved by technology

However, existing grinders or knife sharpeners use rotating grinding wheels as grinding tools for tool grinding, which has a large amount of tool wear and a low tool life, and the grinding wheel body is easy to splash and scatter abrasive particles, which is easy to cause pollution to the kitchen environment.
