JPS6016352A - Electric sharpener for cutting tool - Google Patents

Abstract

PURPOSE:To always stably sharpen a cutting tool, by providing a cutting tool guide groove on the high surface of the case of an electric sharpener for the cutting tool, over it, and providing a cutting tool support block on the low surface of the case of the sharpener, and an auxiliary groove on the extension of the line of the cutting tool guide groove. CONSTITUTION:The portion of a case 5, which is located over a grindstone, is divided into two along the width of the case so that a high and a low surfaces are provided. A cutting tool guide groove 8 is provided on the high surface 6 so that the groove extends along the width of the case 5. An elastic plate 9 for applying side pressure to a cutting tool is provided in the guide groove 8. A cutting tool support block 10 is provided on the low surface 7. An auxiliary groove 11 is provided on the support block 10. The cutting tool is inserted into the guide groove 8 and moved back and forth so that the cutting edge is sharpened over the total length. When the side pressure is not applied to the cutting tool by the elastic plate 9 because of the backward movement of the cutting edge, the cutting tool is fitted in the auxiliary guide 11 so that the tip of the tool does not stagger horizontally. Therefore, the cutting edge is stably sharpened.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric knife sharpener for sharpening knives, scissors, etc.

Conventional Structure and Problems Generally, as shown in FIG. 5, an electric knife sharpener has a disc-shaped grindstone rotated by a motor in a main body case 1, and a portion of the main body case 1 corresponding to the upper part of the above-mentioned grindstone. A blade guide groove 2 is provided in the blade guide groove 2, and when a blade 3 such as a kitchen knife is inserted into the blade guide groove 2, the side of the blade 3 comes into contact with the surface of a grindstone, and the blade 3 is rotated by the rotation of the grindstone. It is meant to be polished.

By the way, the cutlery 3 may be a thin knife, a thick knife, scissors, etc., and the width of the front cutter guide groove 2 must be large enough to sharpen all of these knives. If a thin knife is inserted into this knife guide groove 2, it will wobble in the width direction and stable sharpening will not be possible. is provided to prevent the blade 3 from wobbling. However, the elastic plate 4
/'iThe blade is relatively short compared to the length of the blade guide groove 2, and since it touches a part of the blade 3 and applies lateral pressure, the blade is slid along the guide groove 2 and the blade is removed. When sharpening the tip of the blade, the elastic plate 4 does not apply lateral pressure to the blade 3.
The knife 3 rattles in the guide groove 2, causing waves during sharpening.
There were drawbacks such as rough surface roughness.

OBJECTS OF THE INVENTION The present invention takes into consideration the above-mentioned conventional problems and aims to provide an electric knife sharpener that stabilizes the sharpening condition of cutlery.

Structure of the Invention In order to achieve the above-mentioned object, the present invention divides the surface of the upper part of the whetstone of the main body case into two parts in the width direction of the case, forming a higher surface and a lower surface, and a cutter guide groove is provided on the higher surface. The electric knife sharpener has a structure in which a blade holder is provided with a stand that spans the entire width of the blade holder, and an auxiliary groove is provided on the stand on an extension line of the blade guide groove and continuous with the blade guide groove. It is something.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, reference numeral 5 denotes a main body case, which is provided with a motor and a grindstone (both not shown) rotated by the motor. The upper part of the grindstone of the main body case 5 is divided into two parts in the width direction, and has a high surface 6 and a lower surface 7. A blade guide groove 8 is provided, and this blade qg guide groove 8
An elastic plate 9 for lateral pressure on the blade is provided inside. Also, on the lower surface 7, there is a blade holder that spans the entire width of this world surface.
The cutter holder is provided with the cutter guide groove 8 on the table 1o.
An auxiliary groove 11 is provided on an extension line of the blade guide groove 8 and continuous with the blade guide groove 8.

The electric knife sharpener having the above configuration inserts the knife 12 into the knife guide groove 8 as shown in FIG. In particular, when there is no lateral pressure on the elastic plate 9 such as in the mouth, the blade holder of the blade 12 fits into the relatively long auxiliary groove 11 of the base 10, and therefore the blade Stable stretching is possible without sideways wobbling towards the tip. Further, since the cutter holder 10 is located up to the end of the main body case 5, the main body case 5 is not damaged by the cutting edge.

Effects of the Invention As described in the examples, the present invention divides the surface of the upper part of the grindstone of the main body case into two parts in the width direction of the case, forming a higher surface and a lower surface, and a blade guide groove is provided on the higher surface. The cutter holder is provided with a stand on the lower surface thereof, and the blade vl holder is characterized by a structure in which an auxiliary groove is provided on the stand on an extension line of the cutter guide groove and continuous with the cutter guide groove. The blade can be sharpened stably at all times, and the case will not be damaged by the cutlery, which has great practical effects.
