Summary of the Invention

Problems to be Solved by the Invention

[0004] In the device of Patent Document 1 having a plurality of blade portions, there is room for improvement in terms of the efficiency of peeling off scales.

[0005] The present invention has been made in view of such points, and its object is to enable efficient removal of scales from the surface of a fish body.

Means for Solving the Problems

[0006] The first invention relates to an electric fish scaler, comprising: a main body having a motor; a rotating part rotationally driven by the motor; and a plurality of wing parts provided at intervals from each other in the circumferential direction of the rotating part, projecting radially outward, wherein each of the wing parts has a first end face that can be brought into contact with the surface of the fish body when the rotation axis is perpendicular to the surface of the fish body during rotational drive, and a first corner part provided at the circumferential end of the first end face, the first corner part having an outer contour viewed along the radial direction that is bent perpendicularly or at an acute angle from the first end face.

[0007] In this first invention, the rotating part (wing part) rotates while the first end face is in contact with the fish body surface, so the first corner part collides with the tip of the scales and gouges them out, peeling the scales off the fish body surface and discharging the peeled scales in the circumferential direction of the first corner part. As a result, scales can be efficiently removed from the fish body surface.

[0008] The second invention is the first invention, wherein the wing portion has a second end face that can be brought into contact with the surface of the fish body when the rotation axis is parallel to the surface of the fish body during rotational driving, and a second corner portion provided at the circumferential end of the second end face, wherein the outer contour viewed along the rotation axis is bent perpendicularly or at an acute angle from the second end face.

[0009] In this second invention, the rotating part (wing) rotates while the second end face is in contact with the fish body surface. Therefore, with the axis of rotation parallel to the fish body surface, the second corner collides with the tip of the scales, gouging them out and removing them from the fish body surface. In other words, it is convenient because it can be used interchangeably depending on the situation, with the axis of rotation perpendicular to the fish body surface and with the axis of rotation parallel to the fish body surface.

[0010] The third invention is that, in the first or second invention, in each of the wing portions, the first corner portion is provided at both ends of the first end face on one and the other circumferential side.

[0011] In this third invention, regardless of whether the rotating part rotates in the forward or reverse direction, the first corner portion will come into contact with the scales on the surface of the fish body, and the scales can be peeled off the surface of the fish body. [Effects of the Invention]

[0012] As explained above, according to the present invention, scales can be efficiently removed from the surface of the fish body. [Brief explanation of the drawing]

[0014] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0015] (First Embodiment) - Overall Configuration FIG. 1 shows an electric scale remover 1 (hereinafter referred to as "scale remover") according to the first embodiment of the present invention. This scale remover 1 is for removing scales (S) on the surface (F) of a fish body in a kitchen, outdoors, etc. The scale remover 1 includes a main body 2 having a motor 2a, a rotating part 3 rotationally driven by the motor 2a, a plurality of wing parts 4,..., 4 provided at intervals in the circumferential direction of the rotating part 3, and a cover member 5 covering at least a part of the rotating part 3.

[0016] Although not shown, the main body 2 is equipped with a gear for transmitting the rotational force of the motor 2a, a battery, etc. The scale remover 1 is an electric type in which the motor 2a rotates by the power of the battery to rotationally drive the rotating part 3. The direction of rotational drive of the motor 2a can be both forward rotation and reverse rotation. The main body 2 is provided with a lever 2b for switching the rotational direction of the motor 2a. Also, the main body 2 is provided with a trigger-like switch 2c for switching the ON / OFF of the motor 2a. From the perspective of making the scale remover 1 easy to use outdoors, the battery is preferably a rechargeable one.

[0017] The outer shape of the main body 2 is long in the vertical direction (the rotational axis direction described later), and a gripping part 2d having a curved surface that is easy for an operator to grip during use is provided on the side surface. The dimensions of the main body 2 are not limited, but for example, the length in the vertical direction is about 10 to 25 cm.

[0018] The fish scaler 1 includes a shaft 3a that protrudes downward from the main body 2 and is connected to the rotating part 3. In this embodiment, the shaft 3a is a hexagonal shaft and is integrated with the rotating part 3. The rotating part 3 (wing sections 4, ..., 4) can be removed from the main body 2.

[0019] -Wing section- Each of the wing sections 4, ..., 4 (hereinafter referred to as "each wing section") protrudes radially outward. The radial direction refers to any direction perpendicular to the axis of rotation of the rotating section 3, the radially inward direction refers to the direction approaching the axis of rotation in the radial direction, and the radially outward direction refers to the direction moving away from the axis of rotation in the radial direction.

[0020] Each wing section 4, as shown in Figure 3, is formed in a roughly rectangular shape that is elongated in the direction of the rotation axis when viewed along the circumferential direction, and has thickness in the circumferential direction. The dimensions of each wing section 4 are not limited, but for example, the length in the vertical direction is about 2 to 6 cm. Each wing section 4 has a radial end face 40 and two circumferential end faces 41, 41. The upper half of each wing section 4 is formed in a roughly rectangular parallelepiped shape (or a roughly plate shape with the circumferential direction as the thickness direction) with both the radial end face 40 and the circumferential end faces 41, 41 being roughly flat surfaces.

[0021] As shown in Figure 3, the radial end face 40 of each wing section 4 is formed with its upper part substantially parallel to the rotation axis direction, and below that, it slopes radially outward. As shown in Figures 2 and 5, the circumferential end faces 41, 41 gradually change to a curved shape from the top downwards. Also, as shown in Figure 5, the radially central part of the circumferential end faces 41, 41 gradually bulges outward in the circumferential direction as it goes downwards. At the lower part of each wing section 4, the radial end face 40 gradually narrows as it goes downwards, while the circumferential end faces 41, 41 gradually widen radially outward. At the lower end of each wing section 4, as shown in Figures 5 to 7, the circumferential end faces 41, 41 are connected to each other, and therefore the radial end face 40 disappears. For this reason, when the lower end of each wing section 4 is viewed from below, the radial tip tapers off as shown in Figure 7.

[0022] As shown in Figure 7, a flat surface 42 facing downwards and approximately perpendicular to the axis of rotation is formed at the lower end of each wing section 4. This flat surface 42 has a base end 42a on the radially inward side that gradually widens towards the radially outward side, and a tip end 42b on the radially outward side that gradually tapers towards the radially outward side, converging towards the center line (L) shown in Figures 6-7. Here, the center line (L) is a radial line passing through the center of each wing section 4 when viewed along the axis of rotation. The tip end 42b is formed such that its outer contour is an involute curve.

[0023] Furthermore, when each wing section 4 is viewed along the axis of rotation, as shown in Figure 7, it has a symmetry (line symmetry) in which it overlaps before and after the inversion when inverted about the center line (L) as the axis.

[0024] The flat surface 42 formed at the lower end of each wing portion 4 is a first end surface (E1) that can be brought into contact with the fish body surface (F) when the rotation axis direction is perpendicular to the fish body surface (F) during rotational drive. As shown in Figures 3-4, the circumferential end of the first end surface (E1) is provided with a first corner portion (C1) whose radial outline is bent perpendicularly or at an acute angle from the first end surface (E1).

[0025] Figure 4 shows a magnified view of the first corner (C1) shown in Figure 3. Figure 4 also schematically illustrates how the first corner (C1), moving from right to left in Figure 4, removes scales (S) from the surface (F) of the fish. From the viewpoint of efficiently removing scales (S), the angle θ of the first corner (C1) is preferably 90° or less, preferably 60° or more, and particularly preferably 89°.

[0026] As shown in Figure 3, the first corner (C1) is provided at both ends of the first end face (E1) in the circumferential direction on one side (left side in Figure 3) and the other side (right side in Figure 3) of each wing section 4.

[0027] The upper part of the circumferential end face 41 of each wing portion 4 (the portion substantially parallel to the rotation axis direction) is a second end face (E2) that can be brought into contact with the fish body surface (F) when rotation is driven, with the rotation axis direction parallel to the fish body surface (F). As shown in Figure 6, the circumferential end of the second end face (E2) is provided with a second corner portion (C2) in which the outer contour viewed along the rotation axis direction is bent perpendicularly or at an acute angle from the second end face (E2). From the viewpoint of efficiently removing scales (S), the angle of the second corner portion (C2) is preferably 90° or less, preferably 60° or more, and particularly preferably 90°.

[0028] The second corner section (C2) is provided at both ends of the second end face (E2) in the circumferential direction on one side (left side in Figure 6) and the other side (right side in Figure 6) of the second end face (E2) of each wing section 4, as shown in Figure 6.

[0029] —Cover component— As shown in Figure 1, the cover member 5 is provided on the radially outer side of the rotating part 3. The cover member 5 is shaped to cover approximately half or more of the circumferential portion of the rotating part 3, that is, it is shaped to be approximately U-shaped in a cross-sectional view perpendicular to the rotation axis. In other words, the cover member 5 is formed continuously along the circumferential direction of the rotating part 3 up to the circumferential end 5a. The cover member 5 is formed to gradually widen from the top to the bottom of the rotating part 3. In the approximately lower half of the cover member 5, the circumferential end 5a of the cover member 5 is inclined to expose a larger portion of the wing portions 4, ..., 4. Therefore, the cover member 5 does not obstruct the rotation of the rotating part 3 so that the second end face (E2) of each wing portion 4 comes into contact with the fish body surface (F).

[0030] The lower ends of the wing sections 4, ..., 4 are not covered by the cover member 5, and the lower end 5b of the cover member 5 is located above the lower ends of the wing sections 4, ..., 4. Therefore, the cover member 5 does not prevent the first end face (E1) from contacting the fish body surface (F). The cover member 5 can be removed, and the scale remover 1 may be used with the cover member 5 removed.

[0031] —Effects and Actions— In this embodiment, as the rotating part 3 (wing parts 4, ..., 4) rotates while the first end face (E1) is in contact with the fish body surface (F), the first corner part (C1) collides with the tip of the scale (S) and gouges the scale (S), thereby peeling the scale (S) off the fish body surface (F), and the peeled scale (S) can be discharged in the circumferential direction of the first corner part (C1). As a result, the scale (S) can be efficiently removed from the fish body surface (F).

[0032] By the way, in the fish scaler described in Patent Document 1, multiple blades protrude from the blade-forming surface to remove fish scales. Depending on the type of fish, it is conceivable that the flesh may be easily damaged by contact with these multiple blades. In this embodiment, however, instead of such protruding blades, the first end surface (E1) contacts the fish body surface (F), so damage to the fish body can be suppressed even when used on fish that are easily damaged.

[0033] Furthermore, in this embodiment, the rotation axis along the vertical direction is perpendicular to the fish body surface (F), and the first end surface (E1) facing downwards on each wing portion 4 can be brought into contact with the fish body surface (F) for use. In addition, since the rotating portion 3 is mounted below the main body portion 2, the scale remover 1, which is long in the vertical direction overall, can be brought close to the fish body surface (F) from above for use. For this reason, it is convenient for removing scales (S) in a limited space such as a kitchen sink.

[0034] Furthermore, in this embodiment, since the rotating part 3 (wing parts 4, ..., 4) rotates while the second end face (E2) is in contact with the fish body surface (F), it is also possible to peel the scales (S) from the fish body surface (F) by having the second corner part (C2) collide with the tip of the scale (S) and gouge it out when the axis of rotation is parallel to the fish body surface (F). In other words, it is convenient because it can be used interchangeably depending on the situation, with the axis of rotation perpendicular to the fish body surface and with the axis of rotation parallel to the fish body surface. For example, in Figure 8, the second end face (E2) can be used in contact with the fish body surface (F) in the three parts indicated by the solid curves (near the caudal fin and near the pelvic fin), and the first end face (E1) can be used in contact with the fish body surface (F) in the other parts.

[0035] Furthermore, in this embodiment, since the first corner portion (C1) is provided on both the circumferential side and the other side of each wing portion 4, the first corner portion (C1) can strike the scales (S) on the fish body surface (F) and peel the scales (S) off the fish body surface (F) regardless of whether the rotating portion 3 rotates in the forward or reverse direction. Also, since the second corner portion (C2) is provided on both the circumferential side and the other side of each wing portion 4, the second corner portion (C2) can strike the scales (S) on the fish body surface (F) and peel the scales (S) off the fish body surface (F) regardless of whether the rotating portion 3 rotates in the forward or reverse direction.

[0036] By the way, in order to efficiently remove scales (S) from the surface (F) of the fish, it is necessary to adjust the direction in which the first corner (C1) strikes the scales (S) according to the orientation of the scales (S). For example, as shown in Figure 4, if each scale (S) is floating away from the surface (F) of the fish on one side of the fish, it is necessary to adjust the first corner (C1) so that it strikes the scale from that side. In order to adjust the direction in which the first corner (C1) strikes the scales (S), the user can adjust the position of the scale remover 1 (position of the rotation axis) by moving the hand that is gripping the gripping part 2d, but it is troublesome to adjust the position of the scale remover 1 frequently.

[0037] In this embodiment, as described above, the first corner (C1) can remove scales (S) regardless of whether the rotating part 3 rotates in the forward or reverse direction. For example, as shown in Figure 2, if you want to remove scales (S) on the far side (upper left side) of Figure 2 after removing the scales (S) on the near side (lower right side) of Figure 2, you only need to reverse the direction of rotation of the rotation drive without adjusting the position of the scale remover 1. Therefore, it is convenient as it reduces the effort required for the user to move their hand to adjust the position of the rotation axis (position of the scale remover 1) relative to the fish body.

[0038] Furthermore, in this embodiment, as shown in Figure 7, the shape of the rotating part 3 when viewed along the rotation axis is symmetrical with respect to the center line (L), so scales can be removed from the fish body surface (F) with the same efficiency whether the rotation direction is forward or reverse.

[0039] Furthermore, in this embodiment, since the scale remover 1 is equipped with a cover member 5, the scales (S) are less likely to scatter when being peeled off.

[0040] In this embodiment, the wing portions 4, ..., 4 are not limited to the type of fish being targeted, but are particularly suitable for removing scales from fish such as sea bream, yellowtail, and amberjack. Since the rotating portion 3 (wing portions 4, ..., 4) can be removed from the main body portion 2, the wing portions 4, ..., 4 may be replaced with those of different shapes depending on the type of fish being targeted. In the second embodiment described below, the configuration of the wing portions 4, ..., 4 differs from that of the first embodiment.

[0041] (Second Embodiment) Figures 9-11 show the rotating section 3 (wing sections 4, ..., 4) of the fish scaler 1 according to the second embodiment of the present invention. The following description will mainly focus on the configuration of the second embodiment that differs from the first embodiment.

[0042] In this embodiment, there are five wing sections 4,...,4. The wing sections 4,...,4 have a roughly star-shaped cross-section when cut perpendicular to the axis of rotation and are formed to extend in the direction of rotation. The wing sections 4,...,4 are formed so that their cross-sectional area gradually increases as they move downwards (downwards in Figure 10). As shown in Figure 11, the wing sections 4,...,4 have a roughly star-shaped form when viewed along the axis of rotation.

[0043] As shown in Figure 10, each wing portion 4 is provided with a first corner portion (C1) on both the circumferential side and the other side of the first end face (E1). As shown in Figure 11, the shape of each wing portion 4 viewed along the axis of rotation is not symmetrical on one side and the other side in the circumferential direction. Specifically, the circumferential end face 41 on one side is formed in a substantially flat shape, while the circumferential end face 41 on the other side is formed in a curved shape. Furthermore, the angles of the first corner portions (C1) are also different on the circumferential side and the other side of the first end face (E1). In this embodiment, the angle of the first corner portion (C1) is less than 90° on both the circumferential side and the other side.

[0044] The tip portion 42b of the downward-facing flat surface 42 in each wing portion 4 may be formed such that its outer contour is an involute curve on the other circumferential side (the curved circumferential end surface 41 side).

[0045] In this embodiment, unlike the wing portions 4 in the first embodiment, each wing portion 4 is not provided with a radial end face 40. However, even in the scale remover 1 according to this embodiment, the rotation axis can be used parallel to the fish body surface (F). In this case, when the rotating portion 3 is driven to rotate, the radial tip of each wing portion 4 contacts the fish body surface (F), gouging out the scales (S), and the circumferential end face 41 discharges the scales in the circumferential direction, thus removing the scales (S) from the fish body surface (F). When using the machine with the rotation axis parallel to the fish body surface (F), it is more efficient to have the substantially flat circumferential end face 41 collide with the scales rather than the curved circumferential end face 41.

[0046] In this embodiment, the rotating part 3 does not have a shaft integrated into it.

[0047] (Other embodiments) In the first embodiment, the first corner (C1) and the second corner (C2) are provided on both the circumferential side and the other side of each wing portion 4, but both or one of the first corner (C1) and the second corner (C2) may be provided on only one of the circumferential side or the other side. The motor 2a does not necessarily have to be rotatable in both forward and reverse directions, but if the first corner (C1) or the second corner (C2) is provided on only one side in the circumferential direction, the motor 2a needs to drive the rotating portion 3 to rotate on one side in the circumferential direction.

[0048] The number of wing sections 4 is not limited to four or five; there may be multiple wing sections. [Industrial applicability]
