Description

Technology area

An object of the present invention is to provide a device for cleaning a chopper blade plate, in particular a meat grinder blade and / or a chopper blade used for processing other food products.

State of the art

In the patent document US2226317 (A), a device for cleaning a knife of a meat grinder is disclosed. It is used to simultaneously remove food particles remaining in the holes of the knife plate after the grinding operation. This device has the shape of a disk, is made of plastic and has on one side several elements of the same length, made in one piece with the flat side of the plate of the device. The length of the elements is approximately equal to the thickness of the knife plate, that is, the length of the holes to be cleaned, and the diameter of the elements is only slightly less than the diameter of the holes. In addition, a central elongated shaft is provided which, together with the central hole of the knife plate, is used to define the axial position of the device relative to the knife plate. On the other hand, the angular position of these elements is determined by a rod located on the peripheral edge of the device and entering during cleaning of the knife plate into a groove located on the peripheral edge of the knife plate.

In addition, patent document DE8225151U1 discloses a device for cleaning a shredder blade plate, made in the form of a flat round plate, on one side of which there are several elements of the same length corresponding to the number, diameter and arrangement of the holes of the blade plate and designed to simultaneously remove residues from all holes knife plates. The axial and angular positioning of the cleaning device relative to the knife plate is provided by four elongated cleaning elements symmetrically located on the periphery of the device relative to its transverse axis, three of them being on one side and one on the opposite side. For the convenience of installing the device on the knife plate, the grippers are also located on the periphery.

These cleaning device embodiments are inconvenient and difficult to use. When cleaning the knife plate by placing the devices on the knife plate, apply increased force to remove any crushed food residues from the holes in the knife plate.

Disclosure of the essence of the invention

The object of the invention is to provide a convenient device for cleaning a knife plate.

This problem is solved by a device with the features disclosed in the characterizing part of paragraph 1 of the claims. Additional features and preferred embodiments of the invention are disclosed in the dependent claims.

The foregoing general description and the following detailed description are for illustrative purposes only and are considered to be additional explanations to the claimed invention. Further advantages and features of the invention follow from the descriptions, figures and claims that follow.

The device for cleaning a shredder blade plate described by the invention comprises a housing, a central positioning element, a gripper and at least one working surface on which a matrix of cleaning elements is provided. The tops of these elements form a cleaning surface inclined in the direction from the central positioning element towards the periphery of the knife plate cleaning device.

According to the invention, the shredder knife plate is a circular flat plate with parallel working surfaces, usually made of metal and containing a matrix of holes parallel to its axis. The holes in the knife plate have the same diameter. Depending on the product to be processed, the knife plate can have holes of different diameters, as a result of which the number and location of holes differs depending on the specific plate. The knife plate also has a central hole located coaxially with the axis and is used after the knife plate is mounted on the shredder to support the auger. In addition, a recess is provided on the periphery of the knife plate, which is used to fix the plate during the grinding operation. During cleaning, these elements are used, respectively, to insert the center positioning element into the center hole, and the recess is used to position the side positioning element.

Cleaning the knife plate consists in inserting a suitable cleaning device into the knife plate and pushing food residues out of the holes using the cleaning device elements. To ensure effective cleaning, the location, number and approximate diameter of the cleaning elements correspond to the number, location and diameter of the holes to be cleaned in the knife plate. In addition, to ensure effective cleaning, the length of the protruding cleaning elements should not be less than the thickness of the knife plate.

Preferably, the cleaning elements are cylindrical or conical in shape and may have beveled edges to facilitate insertion into the openings of the knife plate and reduce the cost of preparing the tools.

Preferably, the device comprises two working surfaces on both sides of the housing, on each of which cleaning elements are provided, the size, number and location of which correspond to the type of the blade to be cleaned; this allows one cleaning device to be used to clean two different knife plates.

In a preferred embodiment, the working surface of the device is a plane. Preferably, the central positioning element has a length equal to or greater than the thickness of the blade plate to be cleaned and protrudes above the cleaning elements to facilitate coaxial positioning of the device on the blade plate.

In a further embodiment, the working surface has a conical shape coaxial with the central positioning element.

In a further preferred embodiment, the length of the cleaning elements of at least one of the working surfaces decreases with increasing distance in the direction from the central positioning element to the periphery of the cleaning device. Preferably, the length of the cleaning elements varies in proportion to their distance from the axis of the central positioning element.

In a further possible embodiment, the cleaning elements of at least one working surface have the same length, at least equal to the thickness of the knife plate, the working surface being tapered and the device made of flexible material. The flexible material allows full contact of the work surface with the knife plate during cleaning.

The cleaning device and various elements of this device can be made of solid or flexible material. Preferably, the device is made of plastic, in particular by injection molding.

Preferably, a lateral locating member and finger-recessed grips are provided on the periphery of the device to facilitate and handle the device.

The present invention solves the stated problem of providing an easy-to-use device for cleaning a knife plate. The design of the device requires less effort to clean compared to existing solutions. The process of chopping food in a chopper consists of cutting and pushing food through a knife plate. The food product is cut with a knife sliding along the knife plate. Continuous supply of the product to the cutting and punching zone is provided by the grinder screw. At the end of the grinding process, the last portion of the food remains in the holes of the knife plate, which can lead to a rapid deterioration in its properties. The knife plate has several holes, from each of which you have to remove the product separately, which is a laborious operation. When using a cleaning device with an inclined surface, the cleaning elements closest to the center positioning element first pass through the openings of the blade to be cleaned. By pressing the device further, the following cleaning elements gradually penetrate into the holes of the plate. As a result, the correct positioning of the device relative to the knife plate is facilitated, since only a part of the cleaning elements needs to be correctly positioned. Due to the fact that cleaning is carried out by gradually introducing successive elements into the holes of the knife plate, such cleaning requires less effort from the user.

In order to improve the understanding of the subject matter of the invention, with additional features and corresponding advantages, specific embodiments are described below with reference to the accompanying figures.

Implementation of the invention

The device for cleaning the knife plate 1 in the embodiment shown in Figures 1-4 contains a body 11 in the form of a circular plate, on both sides of which are mutually parallel and flat working surfaces 4 and 5. The working surface 4 contains cleaning elements 6 made in cylinder-like shape and perpendicular to this surface. The diameter of the cleaning elements, their number, location and length correspond to the openings of the knife plate with a diameter of 4 mm, and the length of the shortest cleaning elements 6 is approximately equal to the thickness of the knife plate. The ends 7 of the cleaning elements 6 form a cleaning surface 8 inclined in the direction from the central positioning element 2 located on the axis of the housing 11 towards the periphery 9 of the device. The central housing element 2 has a cylindrical tube-like shape and a length approximately equal to the length of the longest cleaning elements 6, the length of which decreases in proportion to the increase in the distance from the central positioning element 2 to the periphery 9 of the cleaning device for the knife plate 1. On the other hand, the working surface 5 contains cleaning elements 10, made in a cylinder-like shape and perpendicular to this surface. The diameter of the elements, their number, arrangement and length correspond to the openings of the knife plate with a diameter of 2.7 mm, the length of the shortest cleaning elements 10 being approximately equal to the thickness of the knife plate. The ends 13 of the cleaning elements 10 form a cleaning surface 14 inclined in the direction from the central positioning element 2 located on the axis of the housing 11 towards the periphery 9 of the device. The central positioning element 2 has a cylindrical tube-like shape and a length approximately equal to the length of the longest cleaning elements 10, the length of which decreases in proportion to the increase in the distance from the central positioning element 2 to the periphery of the device 9 for cleaning the knife plate 1. On the side surface of the housing 11, there are six symmetrically located recesses 3 that form grips for the fingers. On the periphery 9 of the housing 11, a lateral mounting element 12 is provided, which during cleaning is included in the cutout of the knife plate. Its length is approximately equal to the length of the central positioning element 2. The initial stage of introducing the cleaning device 1 into the knife plate in order to remove the residues of crushed food products from the holes is simplified by the presence of the central positioning element 2 and the side positioning element 12. In the first cleaning stage placing the cleaning device 1 on the knife plate, set the position: the central positioning element 2 relative to the central hole of the knife plate, the side positioning element 12 relative to the cutout on the periphery of the knife plate and, depending on the type of the knife plate being cleaned, several cleaning elements 6 or 10 relative to the holes in the plate. As the cleaning operation continues, further cleaning elements 6 or 10 enter the openings of the knife plate. The cleaning operation is completed when the work surface 4 or 5 comes into contact with the blade to be cleaned.

Although the invention according to the above exemplary embodiment has been described with reference to a preferred embodiment thereof, it is obvious that other possible modifications and variations could be devised without departing from the protected scope of the present invention.
