Description

The utility model relates to household appliances designed for slicing fruits or vegetables. It is most effective to use it at home when cutting fruits or vegetables into cubes, slices or straws.

A device for slicing fruits or vegetables, containing a cutting element mounted in the mites made with the possibility of forcing the cut product through the cutting element (EP 0114074, B26D 3/18, 3/26, 3/00, 3/24, 1984).

However, this device allows you to cut only small fruits or vegetables and in only one direction.

Also known is a device for slicing fruits or vegetables, made in the form of a meat grinder containing a loading hopper, and radial cutting knives mounted on a horizontal shaft with a manual drive. The device further comprises reflectors mounted for adjustable movement along the drive shaft, fixed by means of a lead screw with a nut (RU 2121287, A47J 43/04, B26D 1/02, 1998).

The disadvantage of this device is that it only grinds fruits or vegetables without the possibility of shaping the target product in the form of straws, cubes, etc.

For longitudinal and transverse cutting of vegetables, the device contains a supporting surface, vertical and horizontal knives. A housing with a cover is placed on the supporting surface, inside of which on one side there is a piston with points and slots, equipped with a rod with a gear ruler in mechanical contact with a gear mounted on the axis of the engine. Three systems of knives are installed in the grooves of the body, one of which has a set of parallel knives, the second is made with the possibility of rotation around the axis of the body and rigid fixation in the selected

position, the third system of knives is equipped with a ring that can rotate around the axis of the housing, and its outer surface is made of gear, entering into mechanical contact with another gear wheel, mounted on the axis of the second engine. Inside the ring there is a knife, the plane of the blade of which coincides with the plane of the blade of one of the knives of the first system and is perpendicular to the axis of the body (RU 2110204, A47J 43/25, B26D 3/18, 1998).

The main disadvantage of this analogue is the exceptional complexity of its device and operation.

It is also known a device for slicing fruits or vegetables, containing a cutting element with intersecting blades forming a grate, and an opposing pressure board for pressing the cutting tool on it when cutting, having a region of protrusions supporting the product when cutting, coinciding with the section of blades on the cutting element, when wherein the cutting element is pivotally connected to the pressure plate by means of a swivel joint, allowing the blades to swing downward towards the pressure plate with schennym thereon vegetable or fruit (US 2735467, B26D 3/24, 3/26, 1956).

Closest to the claimed is a device for slicing fruits or vegetables, containing a first cutting element made with intersecting blades forming a lattice, a first pressure board, the working surface of which is made with protrusions forming a pattern corresponding to the pattern of blades on the first cutting element, and installed with the ability to push the cut product through this cutting element, and a manual actuator configured to move the cutting element in the direction of the pressure plate, on which Ora is cut products. In this case, the cutting element is connected to the pressure board using a hinge (RU 2307731, B26D 3/26, 2007).

However, the prototype device does not allow to cut the target product in the form of cubes, since the cutting process in it is carried out in only one direction.

The technical task of the proposed device is to enable the cutting of the target product into cubes.

The solution to this technical problem lies in the fact that the design of the device for slicing fruits or vegetables, containing the first cutting element made with intersecting blades forming a grid, the first pressure board, the working surface of which is made with protrusions forming a pattern corresponding to the pattern of blades on the first the cutting element, for pushing the cut product through this cutting element, and the manual drive, the following changes are made:

1) the device further comprises a pencil case for collecting the cut product, a second cutting element and a second pressure board;

2) the working surface of the second pressure board is made with protrusions forming a pattern corresponding to the pattern of blades on the second cutting element, for pushing the cut product through this cutting element;

3) the first cutting element is mounted on the side wall of the pencil case;

4) the second cutting element is mounted on the upper wall of the pencil case;

5) the manual drive is a crank-slide mechanism;

6) the slider of the crank-slide mechanism is rigidly connected to the first pressure board;

7) the drive handle is attached to the second pressure board;

8) the crank of the crank-slide mechanism is rigidly connected to the drive handle attached to the second pressure board, in a position that enables the movement of the second pressure board in the forcing direction

product through the second cutting element with a dead stroke of the slider.

The causal relationship of the changes made with the achieved technical result consists in the possibility of cutting the initial products in two directions, which ensures the volumetric formation of the target product. This is achieved by installing a second cutting element with a second pressure plate. In this case, slicing is first performed, and then cubes or straws (depending on the installation direction of the blades of the first cutting tool).

An additional technical problem arising from the introduced cutting elements in the second direction is to enable both stages of cutting from a single drive. To solve this problem, the manual drive is a slider-crank mechanism, the slider of which is rigidly connected to the first pressure plate, and the crank is rigidly connected to the drive handle attached to the second pressure plate, in a position that enables the movement of the second pressure plate in the direction of product pushing through the second cutting element with a slider slider.

Figure 1 shows a diagram of a variant of the proposed device.

A device for slicing fruits or vegetables (Fig. 1) contains a first cutting element 1 made with intersecting blades forming a grate, a first pressure board 2, the working surface of which is made with protrusions 3, forming a pattern corresponding to the blade pattern on the first cutting element 1, for pushing the cut product through this cutting element, and manual drive. The device also contains a pencil case 4 for collecting the cut product on its lower cover 5, which also serves as the basis of the structure. In addition, the device comprises a second cutting element 6, made with parallel blades, and a second pressure board 7, the working surface of which is made with protrusions 8, forming a pattern corresponding to the pattern of blades on the second

cutting element 6, for pushing the cut product through this cutting element. The first cutting element 1 is mounted on the side wall of the canister 4; the second cutting element 6 is mounted on the upper wall of the canister 4. The manual drive is a slider-crank mechanism, the slider 9 of which is mounted to move in a slide 10 made parallel to the upper cover of the canister 4 on its side wall perpendicular to the wall on which the first cutting element 1. The slider 9 is rigidly connected with the first pressure board 2 (in this embodiment, the crank-slide mechanism is made with two slide pairs 9, 10 located on opposite side walls Nala 4, each of which slides is rigidly connected to the pressure board 2 to ensure greater rigidity). The handle 11 is attached to the second pressure board 7 and in this embodiment is rigidly connected with the axis of rotation 12 of the crank 13 of the crank-slide mechanism in a position that moves the second pressure board 7 in the direction of forcing the product through the second cutting element 6 with the slider 9 freezing (option is possible execution, in which the handle 11 is mounted to rotate around the axis 12, while the crank 13 is rigidly connected to the handle 11 and is located at an angle that allows the second pressure board 7 to move in the direction n delivering the product through the second cutting element 6 with a dead stroke of the slider 9). The axis 12 is mounted to rotate in sliding bearings, the outer surface of which is attached to the upper wall of the pencil case 4. The cutting elements 1 and 6 are equipped with removable frames for quick reinstallation or removal of one of the cutting elements (in the latter case, the device can optionally work in prototype mode ) The shape and size of the target product are adjusted by installing a knife element with the required distance between the blades.

For dicing, the frame with the second knife element 6 is mounted on the top cover of the canister 4 so that its blades

were parallel to the side wall on which the first knife element 1 is mounted. The handle 11 is set in a position that ensures that the cut fruit or vegetable is placed on the blades of the second cutting element 6 above the top cover of the pencil case 4 (indicated by dots in FIG. 1). After the initial product is placed by further movement of the handle 4 counterclockwise using the pressure plate, the initial product is pressed through the blades of the second cutting element 6 using the pressure plate 7 (see contour lines in figure 1). The initial product is cut into slices that fall to the bottom of the canister 4, with the end surfaces parallel to the side wall of the canister 4, where the first cutting element 1 is installed. During the cutting process with the element 6, the slider 9 is in the dead position, pulling the first pressure board 2 to the right, which ensures free cutting of 6 sliced elements into the bottom of the pencil case 4.

At the end of slicing, the handle 11 is moved clockwise. In this case, the slider-crank mechanism takes the slider 9 out of the dead position, by using the first press board 2 connected with it, pushing the slices located on the bottom of the pencil case through the blades of the first cutting element 1 to cut the target product in the form of cubes falling from the output of this element into the external collection (see dotted lines in figure 1).

Thus, unlike the prototype, the use of the proposed device provides the ability to cut the target product in the form of cubes, which is achieved by cutting the original product in two directions. Moreover, the design of the proposed device is universal. If necessary, it also allows the possibility of cutting in one direction, namely only through the first or only through the second knife element to obtain the target product in the form of slices or straws.
