A device for grinding mainly coffee [1] comprising a housing, a working chamber, a grinding chamber with lid, inside which is mounted a two-bladed knife, driven by an electric motor through a gear mechanism, liponorm, and the lower half-coupling with electric motor 6. On the inner surface of the working chamber is made of a vertical edge and the horizontal part of each blade of the knife is bent at an angle of 5-15aboutto the horizontal plane in the direction of rotation of the knife. The motor has a spring interacting with the grinding chamber, the latter being fastened to the shaft of the upper half-coupling.

The disadvantages of the known device.

Vertical ribs made on the inner surface of the working chamber does not have any impact on reducing the energy consumption of the mill, since the grinding of the product above the blades, creates feericheskie stream. However, the product (coffee beans), under the blades at the bottom of the grinding chamber, inefficient subjected to grinding, resulting in a time of grinding increases, which leads to an increase in temperature grinding and, as a consequence, deterioration of taste (coffee), as well as an increase of energy consumption (energy intensity) through the gland seal (felt).

The design of the mill is not safe, as the inclusion of mills in operation is possible without the lid by pressing the hand on the grinding chamber, and the spring is compressed ka is.

Known attachment to the mixer for grinding coffee [2] comprising a housing, inside which is placed the grinding bowl with lid. On the inner side of the cover has a vertical protrusion on the lower end of which is provided with a tapered notch. The bowl is equipped with a plastic sleeve, through which passes the shaft. The upper end of the shaft is made conical for entry into the conical recess of the ledge, between the vertices of the cones of the protrusion and the recess formed in the gap. On the shaft is mounted the knife. The lower end of the shaft 7 is connected with a tapered sleeve having a splined teeth. These spline teeth mate with the teeth of the shaft of the mixer. The nozzle is provided with a control unit comprising an l-shaped locking lever in contact with the cover and switch the mixer. The gap between the tops of the cones is 0.1 to 0.4 mm

However, in the process of working nozzles (grinders) conical recess in a vertical ledge clogged with dust fraction milled product, and the centrifugal forces acting on the blade during rotation and collision with the milled product, drive shaft tapered top into the recess of the ledge.

When this dust fraction begins to play the role of sand in buochs, which leads to the heating of the shaft as with the nozzles.

Furthermore, the presence of locking the l-shaped lever to turn on and off the nozzle to the work plays following a negative role:

an additional element in the role of reducing the security of use;

the complexity of the entire control circuit of the mixer, as it requires additional structural elements, equipment, labor, etc.

since the shutdown of the drive of the mixer occurs only after opening the lid, due to the fact that the actuator continues to rotate by inertia, is throwing grinding of the camera, which greatly impairs the quality of consumer nozzles;

through an air labyrinth formed between the shaft and the sleeve, is drawn in through the mouth of a small fraction of milled product inside the mixer.

The aim of the invention is to simplify the design of the nozzle, increase reliability and security, and reduce energy consumption.

This objective is achieved in that the attachment to the mixer includes a housing with a grinding bowl, cover and accommodated in the housing shaft with mounted on it multi-working body. The nozzle is supplied mounted on the upper end of the shaft gear clutch and made in the form of the second element and in contact with the bottom of the casing spring washer to preload the bearing unit to the bowl, the cover is made in the upper part of the ejector channels, an axial hole through which passes the shaft; a working body has multiple cutting edges that are located in different planes, and the cover and the reflector are arranged such that they form between them a chamber exhaustion.

In the bottom of the bowl is made hollow to accommodate a bearing Assembly.

The lower end of the shaft has an annular groove.

The locking element is placed in the annular groove.

In the first embodiment, the working body contains two knife element interconnected so that their cutting edges facing outwards, with the knife elements are shifted one relative to the other by an amount equal to 1/3 of the length of the flat area.

In the second embodiment, the working body in the form of knife element, the cutting edges which are symmetrical to its Central axis.

In Fig.1 shows the attachment to the mixer for grinding food, General view; Fig.2 is the same, its working position; Fig.3 section a-a in Fig.1; Fig.4 section b-B in Fig.1; Fig.5 the node I in Fig.1; Fig.6 and 7 of the first embodiment of the cutting of the working body, two projections; Fig.8 WTO food includes a housing 1, inside of which is placed the grinding bowl 2.

The bowl 2 is closed by the cover 3. In the upper part of the housing 1 has an inner ring grips 4. The Cup 2 has an outer collar 5, which serves for fixing the housing 1.

Cover 3 provided with external connecting neck 6 and the axial hole 7 through which passes the shaft 8, are accommodated in the housing 1.

On the perimeter of the lid 3 are at least three protrusions 9, serve to secure with clamps 4 of the housing 1.

In the bottom of the bowl 2 performed outside the recess 10 in which is mounted a bearing Assembly (bearing) 11, through which passes the shaft 8.

The bearing 11 is pressed against the Cup 2 by means of spring washer 12, which rests on the bottom of the case 1 (i.e., associated with the bottom of the case 1) and holds the bearing 11 in the seat (recess) 10.

The upper end of the shaft 8 terminates in a gear coupling 13, which is located in the connecting neck 6 of the cover 3. Transmission clutch 13 is mated with a mating nut (not shown) drive the mixer (not shown).

The lower end of the shaft 8 has an annular groove 14, in which the locking element 15, which serves for fixing the shaft 8 against axial displacement, i.e. the locking element 15 Ustani body 16.

In the upper part of the shaft 8 with the lid 3 separately from fixed pneumatological 17 serving for the active return of the particles of the milled product in the area of the working body 16.

The reflector 17 is a rotating impeller and performs an additional role of pneumoslide that when the nozzle creates a vacuum in the chamber 18 formed between the lid 3 and the impeller 17, i.e., the flow of external air is sucked into the chamber 18 through the neck 6, than let ejection small fraction of grinding out.

The working body 16 is made of at least two of the same knife with two blades or edges 19 and located in different planes.

In the first embodiment, the working body contains two knife element interconnected so that their cutting edges facing outwards, with the knife elements are shifted one relative to the other by an amount equal to 1/3 of the length of the flat area.

In the second embodiment, the working body in the form of knife element, the cutting edges which are symmetrical to its Central axis.

The difference in the performance of the working body 16 purely technological, i.e., in the first embodiment will avalidebuy application of multi-stamp.

In the cover 3 in the zone of the chamber 18 of vacuum (i.e., above the camera 18) performed ejector channels 20 that serve for communication with the external air.

The proposed attachment to the mixer works as follows.

When the cover is open 3 grinding bowl 2 is filled with the product, for example coffee, etc., the Cover 3 is closed by pressing and turning, bowl 2 acts on the spring washer 12. Last after turning to lock the cover 3 is pressing cover 3, which is fixed by the projections 9 in the grippers 4 of the housing 1.

The direction of rotation of the housing 1 relative to the cover 3 coincides with the direction of rotation of the working body 16 and with the direction of the fixing cap 6 with a mixer (not shown).

A larger fraction of the product directly colliding with the blades of the impeller 17, dropped down, i.e., there is an intensive, active return of the milled product into the working area of the cutter body 16. Central cutting edges 19, located in the dead zone of the cutting body 16, are also involved in the refining, which increases the efficiency of grinding (uniformity of grinding and reduces the time of grinding, the temperature is not increased, which is a characteristic sign of improving taste kuteesa, that does not require a mixer protective electrolocation.

When the engine is restarted mixer (not shown) is crushing the food product cutting edges 19 and planes working body 16. At the cutting edge 19 of the knife drop the product of crushing up, down and to the periphery of the grinding bowl 2. The air flow created by the impeller 17, is directed downwards, allowing you to capture more than a small fraction of grinding and send them down into the working area of the cutter body 16; a simultaneous cooling of the milled product.

The proposed attachment for stand mixer allows you to:

to simplify the design, while enhancing the security service by connecting the nozzle to the drive of the mixer by a removable cover;

to exclude the blocking elements (springs, pins, levers, plungers, etc.,) that simplifies the design not only of the nozzle and mixer;

reduce the complexity and consumption of materials in the manufacture (production process);

to reduce the power consumption by reducing the time of grinding, i.e. the amount of energy per unit time decreases;

to reduce energy consumption through the use of pneumoslide;

when virtually unchanged EN nozzle can be used for several types of mixers, for example, "Vortex", "Photon" and other similar landing place under the nozzle (grinders, fast knife), as well as for the modernized electrospace "Khortytsya" production Association "Zaporozhtransformator".
