Luggage for a drive motor connected with the external environment surrounding the body 10 of the vacuum cleaner through the exhaust grill 13, made in the rear. When I turn on the engine and a vacuum chamber 11 for dust collection, air is sucked into the vacuum cleaner through the suction nozzle brush 20 with dust and foreign particles carried by the air from the surface to be cleaned from dust. Bole is specifically the air carrying dust is sucked into the bag 50 to dust in the chamber 11 to collect dust through the suction rod 30 and a flexible hose 40. Dust and foreign particles are separated from air is collected in the bag 50 to dust, while the clean air is out of the bag 50 to dust and be sucked into the chamber to a drive motor through the inlet grating 12A and then thrown out of the body 10 of the vacuum cleaner through the exhaust grill 13.

The cleaner made according to the present invention, includes a housing 10 (Fig. 3 and 4), the discharge grating 80 and the apparatus 90 for jet air supply.

The body 10 of the vacuum cleaner has a similar structure with the case of the known vacuum cleaner, presented in figure 1. In accordance with this, the body 10 of the vacuum cleaner having the t chamber 11 for collecting dust, containing bag 50 for dust chamber 15 to a drive motor that contains the engine 14 mounted therein. Between the camera 11 for collecting dust and the camera 15 to drive the engine is made of vertical wall 12. The vertical wall 12 includes an inlet grating 12A, executed and intended for the message flow of air between the camera 11 for collecting dust and the camera 15 to a drive motor. The camera 11 to collect dust communicated with the surrounding the body 10 of the vacuum cleaner external environment through the suction holes 16 made from the front side of the body 10 of the vacuum cleaner. The chamber 15 to a drive motor in communication with the enclosure 10 of the vacuum cleaner external environment through part 17 for venting, made from the rear of the body 10 of the vacuum cleaner.

According to the design of the intake air into the chamber 11 to collect dust through the suction inlet 16, passes into the chamber 15 to a drive motor through the inlet grating 12A and discharged to the outside through part 17 for air release.

Exhaust grille 80 is installed on the exhaust side 17 for the discharge of air and turned towards the outside of the housing 10 of the vacuum cleaner. Exhaust grille 80 is installed one edge hinged to the body 10 of the vacuum cleaner so as to selectively open part 17 for air release. Guides 81 are made on both sides of the exhaust sieves and 80.

In addition, between the part 17 for the discharge of air and exhaust grille 80 is inserted filter 18 for keeping the fine dust particles still remaining in the air after the air bag 50 to dust when the air is thrown out.

The apparatus 90 for jet air supply includes a connector 91 and the hose 92. The connector 91 includes an expanding portion 93 that is connected with outlet grating 80 and the neck 94 connected with the hose 92. The expanding portion 93 has an essentially rectangular shape in cross section.

In addition, the extending portion 93 covers the exhaust grille 80 and is funnel-shaped with a gradually decreasing cross-sectional area, allowing emitted through the exhaust grille 80 air can be directed at a certain point.

The guide flange 93A made from both sides of the extending part 93. When the guide flange 93A insert and advance along the guide rails 81 outlet grilles 80, the connector 91 is securely connected with outlet grating 80 and covers the discharge grate 80. At the forefront of the expanding portion 93 is made neck 94, having a tubular shape, for connection of a hose 92 to be inserted into it. The neck 94 provided with a groove I made it for connection with a hose 92.

The hose 92 is made of an elastic material that provides the provides the ability to easily move it, and provided with a protrusion 92A, made on the outer surface at one end, in accordance with the groove a neck 94. When one end of the hose 92 is inserted into the orifice 94, the protrusion 92A is in the groove a, thus connecting the connector 91 with the hose 92. Although not shown, at the other end of the hose 92 can be installed nozzle for flow of air.

The action of the vacuum cleaner according to the present invention is described below with reference to Fig. 4 and 5.

When the engine 14 is enabled, the camera 11 to collect dust in a vacuum. Accordingly, air from the environment, carrying dust is sucked into the bag 50 for dust through the suction hole 16. Dust or foreign particles are filtered out and collected in the bag 50 to dust, while the air passes through the bag 50 for dust and passes into the chamber 15 to a drive motor through the inlet grating 12A in the vertical wall 12. As air enters the hose 92 with a smaller cross-sectional area, passing through the connector 91, which has a gradually decreasing cross-sectional area, the air flow flows evenly and with greater speed. Accordingly, since the air discharged from the front end of the hose 92 with high speed, dust and foreign particles effectively blown off.

In addition, the guide flange 93A have the same length, which guides 81 and insert the guides 81 by lowering. Accordingly, the guide flange 93A perform the role of sealing elements which seal the connection area between the rails 81 and the connector 91. The air flow from the outlet grate 80 is directed into the hose 92 without any air leakage into the environment. In addition, even when the user pulls the hose 92, due to the fact that the guide flange 93A connector 91 does not slide along the guides 81, the apparatus 90 for airflow rarely separated from the outlet grate 80.

When the apparatus for flow of air is not used, the connector 91 may be separated from the outlet grate 80 or alternative hose 92 can be separated from the connector 91 to facilitate handling of the vacuum cleaner.

As described above, the guide flange 93A made on both sides of the connector 91 of the apparatus 90 for airflow, vidvigayt in guides 81, performed on both sides of the outlet grate 80. As a result, the apparatus 90 for supplying air flow is not separated from the exhaust grille 80 and between the apparatus 90 for flow of air and exhaust grille 80 is not a gap. In addition, since the guide ribs 93A perform the role of sealing elements which seal the connection area between the apparatus 90 for flow of air and exhaust grille 80, the air can is about to be sent on the hose 92 of device 90 for flow of air without air leakage into the environment.

In addition, since the connector 91 is funnel-shaped with a gradually decreasing cross-sectional area emitted from the chamber 15 to a drive motor of the air can be directed through the connector 91 in the hose 92 effectively with high speed. As air is released from the anterior end of the hose 92 high speed, even sedentary dust and foreign particles blow away by the gusts of air flow from the surface to be cleaned of dust.
