Description

The technical field to which the utility model relates.

The utility model relates to household appliances, namely to juicers for processing products in the preparation of juices from fruits and vegetables.

State of the art

Known juicer containing a container for collecting juice with a discharge pipe, placed in it a drive grater disk with a perforated cone attached to it with a smaller base, a lid having a groove for collecting pulp, and a loading hopper, while in the base of the hopper adjacent to the waste disk, at least two inclined plates are rigidly fixed, while the lower sides of the plates are parallel to the surface of the grater disc and so that they are in contact in the center of the latter, and the upper sides of the plates are located us an angle to the surface of the disk grating so that they are located at one end at the periphery of the hopper, and the other contact each other and the lower sides of the plates in the center of the grating disk.

A juicer on the loading hopper with the ability to move along it has a spring-loaded disk (see US Pat. RF No. 2051607, class A47J 19/02, publ. 10.01.1996).

The disadvantage of this juicer is its low reliability and performance.

A juice extractor is known, comprising a housing, a sleeve extending into the working chamber, a cone-shaped funnel and a grater disk connected to the perforated rotor, while the funnel end facing the groove disk is made with a grater surface and the funnel is connected to the sleeve by a threaded connection, which ensures its longitudinal movement in it and the working chamber is made in the form of a truncated cone directed by a smaller base to the funnel.

In the juicer in a cone-shaped generatrix of the working chamber there are alternating arcuate recesses, tapering in one direction around the circumference and in the plane of the grinding disk (see US Pat. RF No. 2078528, class A47J 19/02, publ. 05/10/1997).

The disadvantage of this juicer is its low reliability and productivity, high metal consumption.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is.

A machine for processing fruits, vegetables and root crops, comprising a housing with a loading funnel, a rotor, a grater disk, a collector and a base with an electric motor installed in it, while it contains pressure plates and a cone installed in the cylindrical funnel, the housing is mounted on the base with flanges and made so that prevents the adhesion of the pulp, and to ensure the removal of the pulp or chips in the collection placed truncated cone, located with a smaller base down. The machine is equipped with a set of grating disks, and a disk is installed on the motor shaft to discharge the crushed product to the periphery of the casing (see US Pat. RF No. 2077252, class A47J 44/00, A47J 19/00 publ. 04/20/1997).

The disadvantage of this machine is its low reliability and consumer properties.

Utility Model Disclosure

The objective of the proposed utility model is the development of a juicer with reduced metal consumption, high reliability and consumer properties.

The technical result that can be achieved using the proposed utility model is to reduce the metal consumption, high reliability and consumer properties.

The technical result is achieved by using a juicer containing a base on which a grinding and extraction unit is installed, consisting of an electric motor, on the shaft of which a filter is made in the form of a conical basket and a movable grater, and through the shock absorbers a pallet with a lid for collecting juice and with a hole is installed for draining into a receiving container and a fixed grater, while a fixed grater is installed on the inner surface of the lid, the latter being equipped with a chipper, while the angle of inclination of the generatrix of the cone fi Three in the form of a conical basket to the axis of rotation is 30 ° ± 5 °, and the working surface of the filter is formed by ribs and longitudinal slots, which are made with the possibility of expansion towards the outer surface at an angle of 90 ° ± 10 ° and are staggered perpendicular to the movement of the juice and pulp.

In the juicer, the filter is made of plastic.

Utility Model Implementation

The juice extractor consists of a base 1, on which the grinding and pressing unit 2 is mounted, while the grinding and pressing unit 2 consists of

electric motor 3 on the shaft 4 of which the filter 5 is fixed, made in the form of a conical basket, which is made of plastic by pressing the angle of inclination φ of the generatrix of the filter cone in the form of a conical basket to the axis of rotation is 30 ° ± 5 °, the working surface of the filter 5 is formed by ribs 6 and longitudinal slots 7, wherein the longitudinal slots 7 from the side of the working surface of the filter 5 are 0.2-0.8 mm wide and expand towards the outer surface at an angle β of 90 ° ± 10 °, while the longitudinal slots 7 are staggered ne perpendicularly movement of juice and pulp.

A movable grater 8 is mounted on the shaft 4 of the electric motor 3 for grinding the product. On the base 1, a pallet 10 is secured through the shock absorbers 9 for collecting juice, while a hole is made in the pallet 10 (not shown in FIG.) To drain the juice into the receiving container (not shown in FIG.), And a lid 11 is installed on the pallet 10, which has a hole 12 for loading the product, a fixed grater 13 is installed on the inner surface of the lid 11, also a chipper 14 is installed on the lid 11.

Juicer operates as follows.

When power is applied, the electric motor 3 starts to rotate the grinding and extraction unit 2 and the movable grater 8 through the shaft 4, the products intended for processing are loaded into the grinding and extraction unit 2 through the hole 12 on the cover 11 and turn into a doughy mass by grinding products with a movable grater 8 and fixed 13. Under the action of centrifugal forces, the doughy mass is thrown onto the wall of the filter 5, made in the form of a conical basket, while the angle φ of inclination of the generatrix of the basket cone to the axis of rotation is 30 ° ± 5 ° and through the longitudinal slots 7 there is a separation of the juice, which enters the pallet 10 and through the drain hole enters the receiving container, while the pulp formed during the squeezing on the inner working surface of the filter 5 is distributed in sectors,

formed by the ribs 6 and under the action of centrifugal forces is discharged from the filter 5 to the chipper 14, where the peripheral speed of the pulp is quenched and it accordingly falls into the container for its collection, and so on until the complete processing of the grinding and pressing of the products loaded into the unit 2, while the shock absorbers 9, which the pallet 10 is fixed on the base 1 reduces vibration loads, and the expanding longitudinal slots 7 at an angle β = 90 ° ± 10 ° allow to exclude their clogging during the extraction of the crushed product (not shown in Fig.), while the slots 7 located in the groove badwords manner perpendicular to the motion of juice and pulp caused by centrifugal forces prevent ingress of juice pulp discharge zone. The ribs 6 on the working surface of the filter 5 act as the blades of a centrifugal pump, which allows you to create excess pressure in the extraction area and, accordingly, increase its efficiency. The air flow created by the ribs 6, allows you to further blow, and therefore cool the electric motor 3, and a significant number of ribs 6 (8-20) with a large diameter of the filter 5 (250-400 mm) allows you to divide the crushed mass into small fragments and prevent concentration in the process spin in one place pulp.

The proposed utility model in comparison with the prototype and other well-known technical solutions has the following advantages:

- reduction of metal;

- increase productivity 30-50%;

- reduction of electricity consumption;

- improvement of consumer properties;

- increased security.
