By design elements:

Lid

It is made of plastic (ABC brand or equivalent). Ensures the tightness of the container. It has sufficient elasticity for transverse deflection along the vertical axis. With a slight physical impact (pressing with a finger), it allows you to change the internal volume of the container in order to create an increased pressure in it for the release of a chemical waste softener - a gel or other liquid placed inside the container.

Frame

It is made from a material similar to the material of the cover. It is a cylindrical bowl of small capacity (approx. 100 ml.) with a small hole (approx. 3 mm.) in the lower part. Provides storage and retention of the gel (liquid) inside. The bottom may have a slight taper to facilitate the flow of the chemical to the hole.

central axis

A plastic or metal axle with a stopper (hat) at the top and notches at the bottom. The stopper fits snugly to the bottom inside the body ensuring its tightness or (in the configuration without a container) keeps the mechanical grinder in its place.

The notches fix a grid, preferably made of metal, in the lower part of the central axis.

Thus, the central axis performs the function of the axis of fastening of all elements of the device, acting as a fastening rod and holding all parts of the device together with the possibility of moving some along its axis.

The axis can be made, for example, in the form of a screw with a nut, and the screw head is placed on top of the device, all elements. In addition to the mesh, they are fixed on the central axis with the possibility of moving along it, and the nut fixes the mesh motionlessly relative to the longitudinal line of the axis itself.

abrasive disc

Represents an emery knife - a disk approx. 10 mm thick. with a diameter slightly smaller than the diameter of the recess in the grid. It is made of abrasive It is rigidly fixed with the bottom part of the container or with a stopper (in the configuration without a container). Grinds small food waste in the area of contact with the surface of the metal mesh due to friction. Contact occurs at the moment of manual pressing of the abrasive disc and turning it around its axis with pressure (applying a slight vertical pressure during rotation).

Disc grater

Metal disc approx. 0.5 mm with holes approx. 9 mm, having pointed edges, according to the type of grater. Grinds small food waste in the zone of contact with the surface of the metal mesh by cutting the food waste falling into the holes with sharpened edges when friction occurs from the manual pressing of the grater disk with turning it around its axis with pressure (applying a slight vertical pressure during rotation).

It is installed either instead of an abrasive disc with the performance of the same functions (grinding) or together with it at the same time (but only one of them, located closer to the grid, works for grinding). The mechanical grinder, which includes an abrasive disc combined with a grater disc, has two working surfaces and can be turned over by the user at will, depending on the type of waste that he wants to grind.

Compression spring

Plastic or metal return spring of low stiffness, length approx. 15 mm., keeps structural elements at a distance and creates a gap between - the mesh and the mechanical food waste chopper.

Cone springs are more stable and do not deflect, causing misalignment.

Such a spring can be fully compressed, while keeping its shape perfectly. The spring can be made both from an element of a round transverse profile, and from an element in the form of a twisted thin tape

Net

Preferably made of stainless steel of small thickness (approx. 0.5 mm.) and according to the profile corresponds to the regular drain of the sanitary sink. The diameter of the holes in the grid approximately coincides with the drain holes (approx. 9 mm.).

Description of the device.

The chopper is designed to remove small fractions of soft food residues (after rinsing plates, pots, etc.)

It is installed in the nest of a regular drain of a sink or bathtub, a pallet used for the same purpose.

Grinding is done manually by applying the muscular force of the hands to rotate the device around its central axis with slight pressure until friction occurs. The central axis is fastened to the grid. By pressing the food residues come into contact with a mechanical grinder and are either crushed by it with forcing through the mesh or cut and also forced through the mesh. At the same time, the produced water supply to the sink (bath, tray) allows you to wash the crushed food residues from the grid. Further removal of crushed residues is carried out together with the flow of water through the drain and regular sewer network. The spring returns all elements of the device to their original position, ensuring its further operation.

When equipped with a container for a chemical waste softener, pressing the lid of the container after the grinding process will force some of the gel or liquid of the anti-clog out of it into the drain siphon, which will facilitate flushing and provide additional prevention of blockages. When the cover is pressed, a slight bend is enough to create excess pressure until it contacts the top of the axle. The gel (liquid) will always flow out of the container a little each time the device is used - rotation with pressure on the outer profile of the entire body, but you can also simply press on the top cover with one finger to release a small amount of gel without rotating behind the body.

If at the same time a spring having a conical profile is used, then it folds into itself around the circumference of the coils, partially performing the function of additional grinding. In a compressed state, the spring can fit into the recess of a mechanical grinder. At the same time, for any type of spring, distortions are not terrible for the device - the longitudinal travel of the device along the axis is too small - about 7 mm.

Thus, the proposed device for grinding small food waste in the sink will allow the consumer to solve household problems of preventing blockages in pipes with minimal environmental damage, without spending too much effort and money on it. The simplicity and reliability of the proposed device has been tested on prototypes. The device can be manufactured commercially using known techniques from known materials.
