Description

Knife Technical Field The present invention relates to the technical field of cooking tools, and in particular to a kitchen knife. BACKGROUND Knives play a very important role in daily kitchen utensils. Kitchen knives used for household cutting. The two cutting surfaces of the knife are smooth blades. The surface of the knife is easy to stick to the food when in use, especially when cutting the food (for example, potatoes) into slices. Obviously, the cut food will be pressed on the surface of the knife under the influence of atmospheric pressure, and it needs to be grabbed manually, which will reduce the speed of cutting food and make it inconvenient to use. SUMMARY OF THE INVENTION Therefore, the purpose of this application is to provide a knife to solve the problem in the prior art that the surface of the knife easily adheres to the food during use. According to a first aspect of the present application, a knife is provided. The knife includes a blade. The blade has a first surface and a second surface that are opposite to each other. The first surface is provided with anti-stick textures. The third surface The two surfaces are flat. According to the knife of the present application, the anti-stick texture is provided on the first surface of the knife. When used, the anti-stick texture can quickly separate the cut food from the first surface of the knife without manual separation, thereby improving the efficiency of cutting. efficiency. In addition, arranging the anti-stick texture on the blade body does not affect the cutting function of the blade. Since the second surface is flat, that is, there is no anti-stick texture, the cutting resistance in the horizontal direction is small during the cutting process, making cutting more convenient. In an embodiment, the tool further includes a blade portion located on one side of the blade body in the width direction and connected to the blade body, and the anti-stick texture is distributed along the length direction of the tool body. A plurality of grooves and a plurality of convex ribs are provided alternately and extend upward from a position close to the blade portion. According to the present application, multiple grooves and multiple ribs can be formed through existing molds. Compared with the groove method, the formation method of the anti-adhesive texture can be simplified, thereby facilitating manufacturing. In an embodiment, the plurality of grooves and the plurality of ribs are formed into a continuously distributed wavy concave-convex structure in the length direction of the tool. In these embodiments, the anti-stick texture with continuously distributed wavy concave and convex structures can meet the anti-stick requirements of different food materials when cutting, and the appearance of the formed knife is more beautiful. In an embodiment, each groove and rib in the concave-convex structure is strip-shaped and has a smooth transition outer surface. The fillet radii of the troughs and crests of the concave-convex structure are R1 and R2 respectively, and R1 :R2=6.5~6.7. Specifically, the fillet radius R2 of the wave peak is greater than or equal to 2 mm. In these embodiments, the rounded corners of the troughs and crests of the concave-convex structure have a suitable radius ratio, making it easier to clean the trough position of the formed concave-convex structure, thereby ensuring the hygienic use of the tool. The rounded corners of the wave crest are relatively small, so the contact area between the wave crest and the food material is small, and it can be supported between the food material and the knife to improve the separation effect. In addition, each groove and convex rib in the concave-convex structure has a smooth transition outer surface, so that the tool will not be too tactile when touched, which can improve the user's experience. In an embodiment, the depth h from the wave crest to the trough of the concave-convex structure is 0.2mm-0.25mm, and the width w between two adjacent wave crests is 5mm-6mm. In these embodiments, the depth from the crest to the trough of the concave-convex structure is a reasonable depth that the current mold can produce uniform wavy anti-adhesive textures, and the depth and width form a reasonable space that can play an anti-adhesive role after testing. , this space can ensure the air flow between the knife and the food, reducing adhesion. In an embodiment, each texture of the anti-adhesive texture extends obliquely with respect to the width direction of the tool. Specifically, the inclination angle of the anti-adhesive texture is 17.5°-35.5. In these embodiments, each texture of the anti-stick pattern extends obliquely with respect to the width direction of the knife, and the ribs at the crest position can separate the food material from the surface of the knife body, thereby improving the anti-stick effect. In an embodiment, the surfaces on both sides of the blade are smooth surfaces, and the blade has a cutting edge on a side away from the blade body, and the gap between the cutting edge and the lower edge of the anti-adhesive pattern is The distance d is 10mm-20mmo. In these embodiments, the surfaces on both sides of the blade are smooth surfaces. By setting a preset distance between the lower edge of the anti-adhesive texture and the cutting edge of the blade, normal cutting function can be ensured. It is not affected by the anti-adhesive texture. Reasonably setting the position of the anti-adhesive texture can achieve an effective anti-adhesive effect. In embodiments, the tool is made of carbon steel, martensitic stainless steel or ceramic material. In these embodiments, the anti-stick texture can be applied to knives made of more materials and has a wider range of applications.
