Abstract

A conic slicing knife with 3D spiral cutting edge for food features that during the cutting of an object, its special cutting edge can perform the pull cutting in the cross-section of the object and advance into inside of the object, so ensuring uniform thickness.

Description

The slicer of cone barrel three-dimensional spiral curve blade

Technical field:

The invention belongs to the food processing tool field.

Background technology:

Food is thinly sliced the history that had thousands of years with traditional vegetable knife.Although at system cutter material, on knife face shape and the hilt style diversified variation is arranged, but can handle very skillfully, be cut into size living delicatessen indefinite, that shape is indefinite, soft or hard is indefinite just like the thin slice of 1-2 millimeter soon, have only the senior slicing technique chief cooker in the catering trade.

Some food slices instrument and slicers have appearred on the market in recent decades.Representational have following three kinds: a kind of is to have a plane positioning slide plate and one and slide plate garage (connecing slice thickness) to exceed the oblique blade cutter of slide plate.On slide plate, cut material is pushed to blade with hand, can thinly slice fragility food; Second kind is that a perk and a radially blade parallel with card above the dish of garden are arranged on garden, the plane dish that rotates around central shaft.The blade revolution is crossed once and is not all split down a slice with the cut material that cutterhead rotates being pressed in the cutterhead top.The third is to be widely used in the cutting frozen mutton in China, is used to cut the slicer of food such as sausage in countries such as America and Europes.Wherein slicer is garden, a plane dish, and week puts the first edge on a knife or a pair of scissors in the garden.Cut material promotes repeatedly to blade on the slide plate parallel with knife face, can thinly slice frozen food.Be not suitable for the indefinite soft diet product of cutting profile.Because of volume is big, expensive being unsuitable for of price promoted to family.

The design concept lattice of above-mentioned slice tool and slicer have been kept implicit in a traditional vegetable knife notion, that is: " thin slice that is cut into is flat, so knife face also must be flat." therefore, blade all is limited to two dimensional surface.The design direction is limited to the part action of finishing manual section with mechanical device.So far not occurring can be not of uniform size, and the soft diet product that shape differs are cut into the slice tool of even thin slice.

In fact, the thin slice that is cut into is flat, blade but not necessarily the two dimension.The inventor has made the slicer that a kind of knife face and the existing thickness positioning function of blade self have the three-dimensional spiral curve blade of draw cut function again, and has applied for patent May 11 calendar year 2001 to China Intellectual Property Office.Mandate, patent No. ZL01223361.7 were obtained on February 6th, 2002.

But ZL01223361.7 patent document hand is proposed, it is the individual program of the section of three-dimensional spiral curve blade, the feature of the slicer of three-dimensional spiral curve blade is confined to " by helical curve from sword to the garden heart that receive concentric metal garden dish from the edge inwardly cutting form, inner edge is that inscribe arc outer rim is the ribbon spiral of circumscribed arc.This ribbon spiral revolves or backspin on its longitudinal axis, and keeping has constant vertical range between the knife face edge of adjacent circumscribed arc and inscribe arc." by such defining, can only design the pancake slicer parallel with horizontal plane with making bus.

Summary of the invention:

The application's content is the slicer that proposes to have with the three-dimensional spiral curve blade of ZL01223361.7 patent different characteristic, i.e. the slicer of taper and tubular three-dimensional spiral curve blade.

The following feature of section cutting tool of tapered three-dimensional helical curve blade: 1, knife face is that the line segment that is formed by connecting by two moving points and the longitudinal axis remains on the angle of choosing arbitrarily between the 0-90 degree is a bus, around the longitudinal axis 3 D belt spiral that forms of rotation continuously; 2, the knife face edge of making by tracks of first the moving point in two moving points comprises in three-dimensional trend and sees two vectorial compositions; A vectorial composition is the draw cut vector, and it has one on (virtual) bearer plane of bus and longitudinal axis formation its direction is consistent with bus by the selected fixedly starting point of design specification, and its length is the monotonic function of bearer plane around the anglec of rotation of the longitudinal axis.Another vectorial composition is the thickness vector, and its starting point is the terminal point of draw cut vector, and its direction is vertical with draw cut vector (up or down), and its length is directly proportional with the anglec of rotation of bearer plane around the longitudinal axis.3, second edge of the knife face of making by the track of second moving point also comprising two vectorial compositions in three-dimensional trend, but except that the length of draw cut vector than the vectorial hysteresis one-period of the draw cut in first edge, other and first edge is identical.

Description of drawings:

A in the accompanying drawing 1 (Ψ) is with A.Be the draw cut vector of starting point, B (Ψ) is the thickness vector that makes progress vertical with A (Ψ).A (Ψ) is α with the angle of positive axis.The anglec of rotation of bearer plane is Ψ.

The specific embodiment:

Embodiment 1: selecting length and the monotonic function between the Ψ of A (Ψ) is logarithmic function.At this moment the mathematic(al) representation at two of knife face edges is:

ρ ₁＝ρ ₀+ρ _a(q ^Ψ/2π-1)sinα(+)kΨ/2πcosα

Z ₁＝Z ₀+ρ _a(q ^Ψ/2π-1)cosα(±)kΨ/2πsinα

ρ ₂＝ρ ₀+ρ _a(q ^Ψ/2π-1-1)sinα-kΨ/2πcosα

Z ₂＝Z ₀+ρ _a(q ^Ψ/2π-1-1)cosα-kΨ/2πsinα

Accompanying drawing 4 is to be bordering on 90 ° as α, q=1.3, (±) get+time the knife face figure.

The slicer of taper and tubular three-dimensional spiral curve blade can put the first edge on a knife or a pair of scissors on any one edge in two knife face edges.Will be on inner surface on outwards outstanding edge monolateral putting the first edge on a knife or a pair of scissors; On inwardly outstanding edge, to monolaterally on the outer surface put the first edge on a knife or a pair of scissors.Cut material is placed on a side outstanding and that put the first edge on a knife or a pair of scissors.

No matter the slicer of third hand tap helical curve blade is taper, tubular or platypelloid type, common advantage of being given all because of its total draw cut principle, that is:

1, the ladder of knife face and blade makes cut material in a single day contact knife face (as leaning on continuity

The gravity of cut material self) just revolved simultaneously by a plurality of blades, cut be and quilt

Cut the full sheet of thing cross section unanimity.Overcome will the cut material of softness both to

The difficult problem that the slide plate pressurization promotes on slide plate again.As long as the restriction cut material is moving with swivel

Get final product.Though cutter hub makes whole slicer obtain letter than common garden dise knife complexity

Change and small-sized.

2, the helicity of blade makes and can extend blade greatly in limited space, with very

Big (can reach 30 times) draw cut ratio carries out draw cut.Especially the length of A (Ψ)

When the rule of pressing the spiral of logarithm changed, the draw cut of each point on the blade was than all

Equate.This becomes a reality with regard to making the soft food of cutting.

Manufacture slicer with the slicer of tapered three-dimensional helical curve blade and can (than using the pancake slicer) littler complete machine size be arranged.

The outstanding advantage of the slicer of tubular three-dimensional spiral curve blade is that two edges of the plane outspread drawing of knife face all are straight lines when adopting the blade of logarithm helical curve.Save material, be easy to blanking, it is simple to put the first edge on a knife or a pair of scissors, and sharpening is convenient.Complete machine is of a size of minimum.
