Description

Before cut the dual-purpose kitchen knife after cutting

The utility model relates to the kitchen knife of the usefulness of cutting the dish in people's daily life.

The kitchen knife of the existing usefulness of cutting the dish, its cutting edge two sides all carry out angular surface grinding processing

The type kitchen knife, to the direction skew of excision dish, the cutting direction of cutting the dish always is irregular cutting angle with the cutting face of being cut the dish to kitchen knife, therefore the dish of excision is sticked on the knife face easily when cutting the dish, and influencing next step cutting, the geometric shape of excision dish also is difficult to rule.Another is that existing kitchen knife cutting edge has only a blade angle, when the cutting soft or hard mingles together material, kitchen knife can not be used to cut hard animal bone and duricrust class material as chopper, chopper can not be used to cut soft dish as kitchen knife, therefore, just many inconvenience have been brought to cutting the dish in people's daily life.

The purpose of this utility model just provide a kind of when cutting the dish the excision dish geometric shape easily the rule, be not easy to make the dish of excision to stick on the knife face again, when the cutting soft or hard mingles together material, can have resemble kitchen knife and two kinds of functions of chopper before cut dual-purpose kitchen knife after cutting.

Its cutting edge of the kitchen knife that the utility model proposed adopt have only one side carry out angular surface grinding process "

" type; its whole cutting edge adopts two different blade angles in addition; the leading portion of kitchen knife cutting edge adopts the less blade angle of angle; its cutting edge length is longer; this section is used to cut the softer vegetables of hardness, melon and fruit and meat material, and the back segment of kitchen knife cutting edge adopts the bigger blade angle of angle; its cutting edge length is shorter, and this section is used to cut harder animal bone of hardness and duricrust class material.

As follows below in conjunction with description of drawings:

Figure one: cut dual-purpose kitchen knife front plan view after preceding the cutting.Figure two: cut dual-purpose kitchen knife reverse side vertical view after preceding the cutting.Figure three: cut dual-purpose kitchen knife leading portion cutting edge profile after preceding the cutting.Figure four: cut dual-purpose kitchen knife back segment cutting edge profile after preceding the cutting.Figure five: original kitchen knife schematic diagram of cutting the dish.Figure six: cut the dual-purpose kitchen knife schematic diagram of cutting the dish after preceding the cutting.

Before cut the dual-purpose kitchen knife after cutting cutter hub 5 (seeing figure one and figure two) adopt the quality steel plate manufacturing, before and after on the camber line of its cutter hub 5 there being the edge of grinding two.A (the seeing figure three) face of leading portion cutting edge 1 (seeing figure one, figure two and figure three) carries out angular surface grinding processing, and b (seeing figure three) face only polishes to handle and makes leading portion blade angle α (seeing figure three) be processed into 6 °～15 °.C (the seeing figure four) face of back segment cutting edge 2 (seeing figure one, figure two and figure four) carries out angular surface grinding processing, and b (seeing figure four) face only polishes processing, makes back segment blade angle β (seeing figure four) be processed into 16 °～25 °.In addition also can be required separately according to the quality and the front and rear sections cutting edge 1,2 of cutter hub 5 materials, cutting edge 1,2 is prevented blunt processing, and processing method is that the knife edge of cutting edge 1,2 is formed anti-obtuse angle γ by a b face side grinding very little d (seeing figure three) face and e (seeing figure four) face ₁(seeing figure three), γ ₂(seeing figure four), this angle are 0 °≤γ ₁＜20 °, 0 °≤γ ₂＜20 °.Leading portion cutting edge length L ₁(seeing figure one and figure two) is greater than back segment cutting edge length L ₂(seeing figure one and figure two).α is less for the leading portion blade angle, is used to cut the softer vegetables of hardness, melon and fruit and meat etc., and the back segment blade angle is bigger, is used to cut harder animal bone of hardness and duricrust class material.

Cutter hub 5 is opened a circular arc 3 (seeing figure one and figure two) near the downside of handle 4 (seeing figure one and figure two), and the pressure F (seeing figure one and figure two) of being convenient to hand like this moves to the middle part of cutter hub 5 as much as possible, makes when cutting the dish more strong.

The upper top of cutter hub 5 is drilled with a hole 6 (seeing figure one and figure two), so that the suspension of kitchen knife.

The material of handle 4 can be decided according to different designing requirements with the type shape.

Cut the signal analysis of dual-purpose kitchen knife when cutting the dish after carrying out original kitchen knife below and before cutting.

Original kitchen knife (is seen figure five) when cutting the dish, kitchen knife M (seeing figure five) produces two power F that arrange object when incision ₁And F ₂(seeing figure five) these two power resolve into the power F of vertical direction ₁', F ₂' and the power F of horizontal direction ₁", F ₂".The power F of vertical direction ₁', F ₂' kitchen knife M is moved downward.The power F of horizontal direction ₂" arrange excision thing R (seeing figure five), the quality of excision thing R is often less, excision thing R since the effect of gravity W1 (seeing figure five) to down predominate, this excision thing R is to kitchen knife M low-disturbance power.The power F of another horizontal direction ₁" desire to arrange cut material Q (seeing figure five) because the quality of cut material Q is often bigger, add when cutting the dish generally all be with hand or other objects by being pressed on the cut material Q, so cut material Q can be considered transfixion.F so ₁" when acting on cut material Q; cut material Q will produce a reaction force f (seeing figure five) and act on kitchen knife M; the size of reaction force f is with the type shape of kitchen knife M; kitchen knife M firmly and the material of cut material Q; the difference of type shape and difference; reaction force f will force kitchen knife to move along V (seeing figure five) direction, this motion is different because of varying in size of reaction force f, different move distances will make the cutting face of cut material Q exist an irregular cutting angle θ (seeing figure five) with the vertical cutter direction down of kitchen knife M, 0 °＜θ＜90 °, the geometric shape of this irregular cutting angle θ influence excision thing R makes it also can rule.Moreover different V directions motion will make kitchen knife M can brush up against excision thing R again after cutting excision thing R, and generally when cutting the dish, kitchen knife M and excision thing R have water, and therefore excising thing R will stick on the kitchen knife M easily, and influences next step cutting.

Before cut the dual-purpose kitchen knife after cutting and when cutting the dish, (see figure six), kitchen knife N (seeing figure six) only produces a power F who arranges object when incision ₃(seeing figure six), this power resolves into the power F of vertical direction ₃' and the power F of horizontal direction ₃".The power F of vertical direction ₃' kitchen knife N is moved downward.The power F of horizontal direction ₃" arrange excision thing T (seeing figure six), the quality of excision thing T is often less, excision thing T since the effect of gravity W2 (seeing figure six) to down predominate, this excision thing T is to kitchen knife N low-disturbance power.The effect that is not subjected to reaction force owing to kitchen knife N does not in the horizontal direction have motion, therefore the vertical cutter direction down with kitchen knife N in the cutting face of cut material S (seeing figure six) is always keeping 0 ° cutting angle, thereby makes the geometric shape of excision thing T will be easy to rule.Moreover because of kitchen knife N does not have motion in the horizontal direction, therefore, kitchen knife N just can not brush up against excision thing T after cutting excision thing T, just excise thing T and be not easy to stick on the kitchen knife N, and next step cutting is not had influence yet.

The utility model is compared with original kitchen knife, cuts the dual-purpose kitchen knife after front the cutting and excises when cutting the dish The geometric shape of dish is rule easily, and the dish of excision is not easy to stick on the kitchen knife, and affects next The cutting in step, can a cutter when the cutting soft or hard mingles together dish dual-purpose, leading portion be cut hardness Soft dish---such as vegetables, melon and fruit and meat, back segment is cut the harder dish of hardness---such as Animal Bone Head and duricrust class material, this kitchen knife handle downside is opened a circular arc, and the pressure of holding kitchen knife is tried one's best To reach, thereby make when cutting the dish more effectively, the upper top of its cutter hub is drilled with a hole, so that The suspension of kitchen knife is deposited.
