As shown in figure 3-5B, the main body 10 of the vacuum cleaner in accordance with the present invention includes a casing 11 for the formation of some internal space, the node 13, which creates a suction force that is installed on the side of the casing 11 for creating the effort suction filtering unit 12 mounted on the side of the node 13, which creates a suction force, with the possibility of connection to the node 13, which creates a suction force in order to have a filter (not shown) for separating impurities from intake air, and a means 20 switching flow channels for selective connection of the Packed node 5 with filter node 12 or node 13, which creates a suction force.

To force the air to flow in a constructive part of the main body 10, connect to him the next few trabona inlet tube 15 is connected between the filter node 12 and the tool 20 switching flow channels to provide a flow of air and impurities in the filtering unit 12, and the guide tube 16 is connected between the filter node 12 and node 13, which creates a suction force to direct the air filtered through the filter node 12, to node 13, which creates a suction force. The main discharge tube 17 is of obedinena side of the node 13, creates a suction force in order to release the air from the node 13, which creates a suction force, output and auxiliary discharge tube 18 is connected between the main discharge tube 17 and the tool 20 switching flow channels to provide the passing part of the air is released to the outside through the main discharge tube 17 of the main discharge tube 17 in the tool 20 switching flow channels.

The tool 20 switching flow channels includes a housing 21 of the valve fixedly mounted on the casing 11, and the valve 22 switching flow channels, combined with the ability to rotate with the housing 21 of the valve for converting the direction of flow of the fluid.

The body 21 of the valve is a cylinder having a certain height, and includes a first through hole 21A, United with the Packed node 5 through the tube 14 connection of the Packed node, and the second through hole 21b formed in such a way that it is located at the same horizontal level with the first through hole 21A and the interval of 90 degrees in the circumferential direction from him, and the second through hole 21b is connected to the main inlet tube 15. In addition, the housing 21 of the valve also includes a third through hole is formed in such a way that it is located on one of Gori is ostalnom level with the second through hole 21A and the interval of 180 degrees in the circumferential direction from him, and the third through hole is connected with the auxiliary inlet tube 18.

In this case, under the force of suction generated by the node 13, which creates increased the suction, the intake air and contamination on the surface (not shown), are absorbed in the filtering unit 12, passing through the Packed node 5, the sliding tube 4 (shown in figure 1), the tube 14 connection of the Packed node, the first flow passage 22A and the main inlet tube 15. In a filtering node 12 impurities are separated from the air filter 12, while impurities remain in the collection of the filtering node 12, and the air comes out from the housing 10 through the guide tube 16 and the main discharge tube 17. In this case, the auxiliary discharge tube 18 extending from the main discharge tube 17 is closed by the valve 22 switching flow channels, and therefore, the air passing through the main discharge tube 17, is released to the outside of the casing 11 of the main body 10.

Meanwhile, in order to realize displayed on figv the cleaning mode by deflating with a vacuum cleaner in accordance with the present invention, the user switches the valve 22 switching flow channels in the cleaning mode by deflating to connect the Packed node 5 with the main discharge pipe 17 through the first flow passage 22A and the auxiliary discharge tube 18.

In this case, by connecting the third through hole 24A on the exhaust side of the second flow channel filter node 12 through the main inlet pipe 5, is he the air flows into the filtering unit 12 through the second flow channel 22b and the main inlet pipe 15 under the force of suction, created by node 13, which creates a suction force, the air in the filter node 12 flows into the node 13, which creates a suction force, through the guide tube 16, with a portion of the air comes out from the housing 11 through the main discharge tube 17, or the remainder of the air is produced in the first flow channel 22A through the auxiliary discharge tube 18. The air in the first flow channel 22A, blows away the dust on the window frame or in any excavation at release it through the Packed node 5.

As described above, in the vacuum cleaner in accordance with the present invention by installing a means of switching flow channels for switching a flow channel of air between the Packed node filter node and the auxiliary exhaust pipes of the site, creating a suction force, creates the possibility of removing contaminants, such as dust, by getting rid of dust using a powerful jet of air, resulting in much greater capability for the use of a vacuum cleaner.

In addition, using the same hose as before, you can simplify the design of the vacuum cleaner and to facilitate the cleaning operation. And you can reduce costs, minimize production costs and to diversify the functions of the vacuum cleaner.

FIELD: processes for collecting dust, cleaning rooms, removing dust from electronic devices, industrial equipment.

SUBSTANCE: method comprises steps of using controlled compressed air pulses for tearing-off dust particles from rigid surface in hard-to-reach places, for mixing dust particles with air and then for removing them by means of pulses of directed suction flows of air created with use of vacuum cleaner. In suction zone upon dust stuck to surface of cleaned object pulses of directed compressed air flows are acted for tearing dust particle from surface by means of compressed air stream and for mixing them with air. At process of cleaning changing characteristics of compressed air pulses, orientation and shape of air streams while changing frequency of compressed air pulses, their duty factor, amplitude of flow rate and pressure of compressed air according to condition providing maximum activation of dust without damaging members. Pulses of compressed air flows are applied by bursts during phase of dust activation. At cleaning process number of pulses in bursts, shape, duty factor, frequency of pulses, duty factor of pulse bursts are changed according to condition providing maximum rate of dust activation for cleaned surface. Novelty is feed of train of short pulses in phase of dust activation before feeding one long pulse in order to create pulsating flows of compressed air providing pressure drop. It allows accelerate dust particle tearing from surface due to creation of pulsating turbulent air flows near cleaned surface. Dust-laden air is sucked by means of pulses of directed suction flows of air. Method may be used in home and industrial rooms for cleaning complex-profile surfaces.

EFFECT: enhanced quality and rate of cleaning complex-profile articles.

FIELD: engines, pumps.

SUBSTANCE: essence of the method consists in formation of vortex type air flow due to the input of impulses of the compressed air directed flow along a helical trajectory with simultaneous formation of a coaxial helical flow of sucking air. Vortex-type flow facilitates rapid activation and dust entrapment due to a flow rotation along a complex helical trajectory. During the process of activation and evacuation of dust the direction of the compressed air flow and the sucking flow can be reversed at every subsequent impulse or within one impulse. The suction air of the compressed air flow sucks dust along the central duct through a suction nozzle.

EFFECT: increase of quality and speed at cleaning rooms or electronic devices.
