The invention relates to household appliances, namely, devices for mixing drinks.

Known mixer containing the drive with a set of working tools, including a framework Corolla with two vertical posts, and a fixture for fixing the working bodies to the shaft of the actuator (Application Germany No. 2156789, MKI A47J 43/08, publ. 1978).

A disadvantage of the known device is its high complexity, low reliability in operation.

Known mixer containing the drive with a set of working tools, including a framework Corolla with two vertical posts, and a fixture for fixing the working bodies to the shaft of the actuator. While the mixer is equipped with additional working body, with vertical racks reinforced annular element with a cylindrical protrusion on the inner side of the ring, while the ring element has a notch and the protrusion of the teeth (as the USSR №1007647, MKI A47J 43/04, publ. 1983, BI No. 12).

A disadvantage of the known device is its high complexity, low reliability in operation.

The closest in technical essence of the present invention is a continuous mixer comprising placed inside the annular source rotating magnetic fields of the mixing chamber of a nonmagnetic material entered into the ferromagnetic body and, inlet and outlet piping. The source of the rotating magnetic field is made in the form of sequentially placed along the mixing chamber of the three-phase AC electromagnets producing current in the adjacent areas of the chamber a magnetic field with opposite direction of rotation (see A.S. USSR №423489 BI No. 14, 1974).

A disadvantage of the known designs is the inability to mix the stagnant liquid and the inability to use in the laboratory.

The basis of the invention is tasked allow mixing of stagnant fluids, as well as improve the reliability of the mixer in operation.

The problem is solved due to the fact that the mixer containing the mixing chamber of a nonmagnetic material, the annular source rotating magnetic field and a ferromagnetic body, according to the invention, the mixing chamber is made in the form of a Cup, a ring source rotating magnetic fields is made in the form of a solenoid coil mounted on the outside of the glass, and the ferromagnetic body made in the form of turbine, covered with plastic between the bottom of the glass and the tabs, reinforced glass, installed two position sensor turbine, located one at the bottom of the glass, the other at the tabs.

The invention has), the governmental differences, because of the known solutions with features that distinguish this solution from the prototype not found.

Figure 1 - General view of the beater,

figure 2 - cross section of a mixer (turbine not cut),

figure 3 is a view along arrow a,

figure 4 is a view along arrow B,

figure 5 - cross section of the turbine.

The mixer consists of a Cup 1, the windings of the solenoid 2, installed on the outside of the glass, turbine 3, located on the bottom of the glass. The turbine 3 is made of a ferromagnetic coated material, neutral to mix liquids, such as food polymer. In the upper part of the glass, parallel to its bottom, set the tabs 4. Two position sensor turbine 5 is installed on the outer surface of the Cup 1 at the level of the ledges and the bottom.

The turbine 3 is made so that it has shifted the centre of gravity, which provides a constant orientation of the turbine 3 with respect to the bottom of the glass 1 or the diameter of the turbine 3 is approaching the inner diameter of the Cup 1, resulting in the turbine 3 may be "moving" landing relative to the inner bore of the Cup 1.

The projections 4 are designed to limit the stroke of the turbine and provide free pouring the mixed liquids from the Cup 1.

The mixer operates as follows.

In the Cup 1 are filled miscible liquid. At this time, the turbine 3 is located at the bottom of the Cup 1. This is ogenyi sensor 5 is closed and a voltage is applied to the coil of the solenoid 2, an electromagnetic force in the inside of the Cup 1, turbine 3 begins to rise up. When the turbine 3 reaches the position of the top sensor 5, the electrical circuit powering the solenoid coil 2, is opened. Under its own gravity turbine 3 is lowered to the bottom of the Cup 1. At this time, due to the sensor 5 at the bottom of the Cup 1 again closes the electrical circuit powering the solenoid 2 and the turbine 3 begins to rise up. The process is repeated. When raising and lowering the turbine 3 rotates. The rotation is carried out by passing a laminar flow of the mixed fluids through the turbine blades 3. All this leads to intensive mixing of the liquids. After stirring loses power winding 2 and the mixed liquid is poured from the Cup 1. When this turbine 3 is retained in the Cup 1 by the projections 4.

In order ferromagnetic turbine 3 is not in contact with miscible liquids, it is covered with a film of material, neutral to mix liquids, such as food polymer.

Turbine 3 may be performed, for example, as follows.

The ferromagnetic circle around the ring and made the petals, as shown in figure 4. In the center of the ferromagnetic circle has the goods in the form of a cylinder, which provides the offset center of mass of the turbine 3. Along the perimeter of the magnetic disk can be performed in the ring of the dielectric is Rick, which will serve as a guide during movement of the turbine up and down.

The protrusions 4 may be made of polymer, inert to mix the liquids, and to have the outer diameter, the size of which provides a fixed ("driving") landing in relation to the size of the nozzle holes 1. The ratio of the outer diameters of the protrusions 4 and the inner Cup 1 allows you to remove it from the Cup 1, the protrusions 4 and the turbine 3, if necessary.

As position sensors 5 can be used, for example, reed switches.

Was made a prototype of the proposed mixer, which was successfully tested. The proposed device can be used for mixing volatile liquids, such as hydrochloric and sulfuric acids in the laboratory.

The mixer containing a mixing chamber, an annular source of rotating magnetic fields and ferromagnetic body, wherein the mixing chamber is made in the form of a Cup, a ring source rotating magnetic fields is made in the form of a coil of the solenoid is placed on the outer surface of the dielectric glass, and the ferromagnetic body is made in the form of a turbine with a displaced center of mass, covered with plastic and located between the bottom and the tabs, reinforced parallel to the bottom inside of the Cup, with two position sensor turbine installation is Lena on the outer surface of the glass at the level of the ledges and the bottom.
