Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric knife that is mainly useful for cutting live fish such as sea bream flounder into three or five pieces.

[Conventional technology]

Traditionally, when preparing live fish for sashimi, etc., use a sharp knife to remove the scales, then insert the knife between the bones and the meat, and cut along the spine to avoid getting any meat on the spine. I was trying to separate one body from the other.

When the body is divided into both halves and the backbone part, it is called 3-piece grated, and when each body is divided from the lateral line into the upper and lower parts of the body, it is called 5-piece grated.

[Problem that the invention seeks to solve]

However, using a Deba knife to cut down live fish in this way requires considerable skill, and it is especially difficult to cleanly separate one fish from the backbone without leaving any wasted meat. There was a problem that only experienced and professional cooks could cook the food to a satisfactory degree. In addition, few households were equipped with such sharp knives, and if the knife was not sharp enough, the cuts would not be smudged and the appearance would be poor.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention removably attaches a two-blade cross-blade, in which a fixed blade and a movable blade overlap, to the tip of a cylinder, and a movable blade inside the cylinder. It has a built-in drive device that reciprocates left and right or front and back, and the movable blade is separably pressed into contact with the fixed blade via a bullet.

[Effect]

According to this invention, the movable blade in the two-blade type horizontal blade is reciprocated at high speed in the left-right direction or front-back direction by the drive device, so meat can be easily cut and the fixed blade can be moved along bones and skin. By moving the cutting edge at the same time, no unnecessary meat is left behind on these bones and skin, and the cuts are cleanly separated. The fixed blade serves to protect and guide the movable blade, and the cross blade can be taken out from the cylindrical body and both blades can be separated, making it easy to clean after use.

〔Example〕

1 to 4 show an embodiment of the present invention. The electric knife of this embodiment has a movable blade that reciprocates in the left-right direction.
As shown in the figure, a two-blade blade in which a rectangular fixed blade 2 with a linear cutting edge perpendicular to the cylinder axis and a movable blade 3 of approximately the same shape are superimposed on the tip of a hard plastic elliptical cylinder 1 that can be held in one hand. The cylinder body 1 has a removably attached side blade, and a rechargeable secondary battery 4, a motor 5, a crankshaft 6 that changes rotational motion into left and right reciprocating motion, etc. are built into the cylindrical body 1. A switch 7 is provided.

The cylindrical body 1 has a socket opening 8 at the rear end and is used for charging and AC using a charging and AC adapter 9, and has a movable blade push button 18 in the center of the side surface, and a side blade mounting part. A waterproof means (not shown) is provided using a packing material.

The two-blade type horizontal blade has a flat side surface 1 of the cylindrical body 1.
0, the fixed blade 2 is installed on the outside at a required inclination angle α, for example approximately 35°, and the length of the straight cutting edge is approximately 12 cm. Note that the cross-cutting blade can be replaced by appropriately selecting one with a long cutting edge or one with a short cutting edge depending on the size of the fish body.

The fixed blade 2 is somewhat larger than the movable blade 3, and is made to protrude slightly from the movable blade 3 when not in use to protect the movable blade 3 and serve as a guide when it is placed along the backbone of a fish.

The fixed blade 2 and the movable blade 3 have a slightly concave inner overlapping surface where they come into contact to improve the adhesion of the cutting edge line, and the opposite outer surface is formed into a sloped blade surface to improve cutting quality. It's on.

As shown in FIGS. 3 and 4, the horizontal blade has a fixed blade 2 and a movable blade 3 that are swingable via a fulcrum 11, and both blades are in contact with each other by a planar U-shaped coil spring 12. However, when the presser piece 13 fixed to the movable blade 3 is pressed, both blades open (see FIG. 4), making cleaning after use easier. The fulcrum 11 is simply a protruding piece, and the movable blade 3 is supported by the coil spring 12 so that it can reciprocate left and right as well as move back and forth, so the movable blade 3 can reciprocate left and right at high speed while remaining in close contact with the fixed blade 2. can.

When in use, the movable blade 3 is caused to reciprocate in the left-right direction by moving the push-out button 18 forward to cause the blade edge to protrude from the blade edge of the fixed blade 2 by a required distance l of, for example, 0.3 to 0.5 mm.

The crankshaft 6 is directly connected to the motor 5 of a vertical rotating shaft, and has an eccentric rod 14 at its upper end.
4 protrudes into the groove of the movable blade support 15 and causes the movable blade 3 to reciprocate left and right at high speed. Note that a pair of small protrusions 17 (see FIGS. 3 and 4) of the side blade are inserted into a pair of small through holes 16 (see FIG. 1) at the upper end of the movable blade support 15.
(see figure) are removably inserted and connected.

FIG. 5 is a schematic diagram of main parts showing another embodiment of the present invention. In this embodiment, the movable blade reciprocates in the front and back direction, and the motor 5' with a horizontal rotating shaft is used.
A horizontally placed crankshaft 6' is directly connected to the movable blade 3', so that the movable blade 3' can reciprocate back and forth at high speed.

In the electric knife, the cutting edges of the fixed blade and the movable blade may be formed in a straight line as described above, or may be formed in a slightly rounded curved shape.

When using the electric knife according to the present invention, as shown in FIGS. 6 and 7, when cutting live fish into eight pieces, for example, the protruding fixed blade 2 is first used to make cuts along the side line. , and then, while reciprocating the movable blade 3 at high speed, move the fixed blade along the spinous process 20 of the spine and move both blade tips toward the dorsal or ventral edge of the fish body. 2, the movable blade 3 rushes into the boundary between the meat 21 and the spinous process 20, so no wasted meat is left on the spine, and the bone and meat can be separated cleanly at the cut end. From this state,
When the meat 21 is turned halfway to the side of the fish body as shown in FIG. 7, the skin is still continuous with the dorsal or ventral edge on the underside of the meat 21. When the fixed blade 2 is moved along the skin, the movable blade 3 enters the boundary between the meat 21 and the skin, making it possible to continuously peel the skin without leaving any waste on the skin.

Furthermore, after use, this electric knife can be used for a long period of time by removing the side blade from the cylindrical body and cleaning the brush, etc., and sharpening the edges of the fixed blade and movable blade with a whetstone.

The electric knife of the present invention is also useful when thinly cutting meat other than fish.

〔effect〕

As described above, the electric knife according to the present invention has a two-blade horizontal blade, a fixed blade and a movable blade, removably attached to the tip of a hand-type cylindrical body with a built-in cordless drive device. It is a device that allows you to easily cut meat and obtain beautiful cut fillets by simply pressing the edges of both blades against the meat and moving them, and it is especially useful for separating meat from the bones or skin of fish that are difficult to disassemble without wasting it. It has the advantage that it improves yield, does not require skilled techniques, and is easy to clean and repair after use.
