Description

The utility model relates to household goods, in particular to hand knives for peeling vegetables and fruits.

Known knife for cleaning vegetables and fruits, containing a handle and connected to it two pointed plates of a curved profile, articulated between them, with blades forming a gap along the dividing lines of the plates (Patent for invention No. 12160 of 10/18/1926).

Using this knife allows you to effectively remove the peel from fruits of the same diameter and with a flat surface, because the curved profile of the plates covers the surface of the fruit during processing.

However, the use of this knife for cleaning fruits of different sizes with an uneven surface does not allow efficient cleaning, as the curvature of the plates is not adjustable. In addition, this knife is structurally complex and includes hinge elements that corrode and break under the influence of a humid environment.

Closest to the proposed technical solution is a knife for peeling vegetables and fruits, containing a handle and two plates attached to it with blades connected by a spacer between them, changing the curvature of the plates (USSR Author's Certificate N 1162402 of 03/04/1982, publ. 06/23/1985) .

The use of this knife allows you to reduce waste when cleaning different-sized fruits with an uneven surface by bending the blades at different radii.

The disadvantage of this known knife, the closest to the claimed one, is the complexity of its design, which requires the use of a special structural and technological adjustment for the curvature of the surface of the processed fruits, which leads to an increase in the time of their cleaning and reduces productivity. In addition, cleaning fruits with an uneven surface with this knife is inefficient, because bending the knife profile at any angle to the surface of the cut does not allow maneuvering the blade when processing uneven surfaces, impairing the quality of cleaning and reducing its productivity. At the same time, this knife is structurally complex and includes movable elements that undergo corrosion and destruction under the influence of a moist environment.

The proposed utility model solves the problem of creating a simple knife design that allows for effective manual cleaning of fruits.

The technical result of the proposed utility model is to increase the breadth of the blade of the knife on the curved surface of the fruit, contributing to the removal of a wide surface layer from the processed fruit, and the convenience of maneuvering the knife to adjust it in the process of processing the fruit to the relief of their curved surface.

In addition, the technical result of the proposed utility model according to the first embodiment is also to increase the strength and reliability of the knife, due to the increase in the cross section of the axial moment of inertia of the working plate, contributing to an increase in its rigidity.

The specified result is achieved by the fact that in the knife for peeling vegetables and fruits according to the first embodiment, comprising a handle and a working plate with a curved profile with a sharp end, perforated, connected to it

a slot located along the midline of the plate profile and dividing it into two opposite sections: a guide and a cutting blade, which is one of the edges of the slot located below the level of its other edge at a distance corresponding to the depth of cut ... curved profile of the working plate in plan made crescent, and the shape of its slit in plan is formed by two unidirectional arcuate edges that meet at the ends of the plate, while in cross section the shape of the working plate formed by the guide and cutting sections made arcuate.

This result is achieved by the fact that in the knife for peeling vegetables and fruits according to the second embodiment, comprising a handle and a working plate with a curved profile with a sharp end, a perforated slot located along the midline of the plate profile and dividing it into two opposite sections: a guide and cutting with a blade, which is one of the edges of the slit located below the level of its other edges at a distance corresponding to the depth of cut ... the curved profile of the working plate in the plan is made crescent, and the shape of its slit in the plan is formed by two unidirectional arched edges that meet at the ends of the plate, while the guide and cutting sections in cross section are located at an obtuse angle to each other.

In addition, the execution of the outer part of the profile of the plate from the side of its cutting section with serrations allows you to scrape off defects from the surface of the fruit and to separate the peel of soft, in particular boiled fruit.

The drawings show the design of the proposed device:

Figure 1 - General view of a knife for peeling vegetables and fruits, the first and second options;

Figure 2 - section aa in figure 1, the first version of the knife for cleaning vegetables and fruits;

Figure 3 - section aa in figure 1, the second version of the knife for cleaning vegetables and fruits.

The knife according to the first and second variants consists of a handle 1 (Fig. 1) and a sickle-shaped working plate 2 in plan with a sharp end cut 3 for removing defects from the hollows of the fruit surfaces, a perforated slot 4 located along the midline of the profile of the working plate 2 and separating it into two opposite sections: guide 5 and cutting 6 (Fig.1-3). The shape of the slit 4 in the plan is formed by two unidirectional arched edges 7 and 8, which are joined at the ends of the plate, one of which 8 is located on the guide section 5 of the working plate 2, and the other edge 7 is located on the cutting section 6 of the plate 2, sharpened and forms a blade located in a cross section below the level of the other edge 8 of the slit 4 at a distance corresponding to the depth of cut "h". The outer part of the profile of the plate 2 from the side of its cutting section 6 has notches 9 for scraping defects from the surface of the fruit and for separating the peel of the soft, in particular boiled fruit.

In the knife according to the first embodiment, the cross-sectional shape of the working plate formed by the guide 5 and the cutting 6 sections is arcuate (Fig. 2), increasing the axial moment of inertia of the working plate 2 in the cross section, i.e. increasing its rigidity and reliability of the knife as a whole.

In the knife according to the second embodiment, the guide 5 and the cutting 6 sections in the cross section are located at an obtuse angle <α to each other (Fig. 3), ensuring the manufacturability of the knife and the free removal of the surface layer removed from the fruit from the working area.

The knife works as follows.

When moving using the handle 1 of the working plate 2 (Figs. 1, 2 and 3) along the surface of the fetus, the edge of the edge 7 covers the surface of the fetus along the perimeter and cuts off a thin layer corresponding to it

the depth of cut “h”, which is immediately removed through the slotted slot 4. The sickle-shaped profile of the working plate 2 and the arcuate shape of the slot 4 with edges 7 and 8 provide a wide coverage of the fruit surface during processing, thereby contributing to the removal of a wide surface layer with processed fruits and accelerate the process of their high-quality processing. In addition, these design features make it easy to maneuver the knife blade 2 in any direction using its handle 1, allowing it to be adjusted to the surface relief of the processed fruit with any irregularities without the use of special technical means.

The corresponding cutting depth "h" is provided by the location of the blade edge 7 of the slotted gap 4 below the level of its other edge 8.

The proposed design of the knife according to the first and second options due to the combination of its essential features allows us to simplify the design of the knife and its stamping, increase its strength, as well as improve the quality and productivity of manual cleaning of fruits by increasing the width of the surface of the fruit blade of the knife, contributing to the removal of a wide surface layer from the processed fruit, and the convenience of maneuvering with a knife to adjust it to the surface relief of the fruit during processing.
