In addition, in the conventional cyclone device, because the air passes through the hole to release the air, formed on one side of the cyclone unit without the air flow direction after passing through the discharge holes of the secondary cyclones, facing upward, the air that has passed through the discharge holes of the secondary cyclones, collides with the top cover cyclone device and creates noise. In addition, due to the collision of air passing through the discharge holes of the secondary cyclones, with the top cover, the air flow becomes turbulent, causing a pressure loss.

Details will be made reference to embodiments of the present invention, examples of which are illustrated in the drawings, in which similar reference items refer to the same elements. Options for implementation are described below to explain the present invention with reference to the figures.

Figure 1 cyclone vacuum cleaner in accordance with a variant assests the of the present invention contains the suction unit 1 for suction of polluting particles together with air by the suction force and the housing 2 for collecting contaminant particles, suction suction node 1.

The case 2 and the suction unit 1 is connected by means of a connecting hose 3a and the connecting tube 3b to the suction force generated in the housing 2, was passed through them in the suction unit 1.

The housing 2 is connected on the front side with connecting hose 3a to ensure the passage of air through the connection hose 3a and contains 4 hole to release air in its upper part, through which, after removal of contaminating particles using a cyclone device 10 located in the housing 2, the air comes out of the housing 2. The housing 2 is made from node 5 blower fan to create devaysa force and the suction force. Node 5 blower fan includes blower fan 5a to create a suction force in rotation and the motor 5b to rotate the blower fan 5a. Node 5 blower fan connected to the cyclone device 10 via a connecting tube 6.

Cyclone device 10 used in the cyclone vacuum cleaner in figure 1, will be described with reference to figure 2-5.

As shown in figure 2, the cyclone device 10 in accordance with the embodiment of the present invention includes a housing 20 of the device containing essentially cylindrical outer container 21 and the inner construction of the second container 22, located in the outer container 21, the primary cyclone 30, located in the inner container 22, for the primary separation of contaminants from the intake air into the housing 20 of the device, many of the secondary cyclones 40 located on the outer container 21, for secondary separation of pollutants from the air leaving the primary cyclone 30.

Cyclone device 10 further comprises air intake hole 11 formed on the lower side of the housing 20 of the device, and the vent hole 12 formed in the side of the upper part of the body 20 of the device, so that the air hole 11 is communicated with the primary cyclone 30, and the vent hole 12 communicates with the secondary cyclones 40. In addition, after the release of the primary cyclone 30, the air is split by channel 51 to the flow direction, formed in the cover 50, and is evenly distributed in the secondary cyclones 40.

The primary cyclone 30 contains essentially cylindrical chamber 31 of the primary cyclone, located in the center at the top of the inner container 22, and the first dust-collecting tank 33, formed by a dividing wall 32 in the inner container 22 for collecting contaminant particles initially separated by means of centrifugal force.

The secondary cyclones 40 contain many cameras 41 W the ranks of cyclones, located on the circumference in the upper part of the outer container 21 and having the same shape and size, and many of the second dust tank 42 formed in the lower part of the outer container 21, for collecting contaminant particles, again separated by many cameras 41 of the secondary cyclones, respectively. Each of the chambers 41 of the secondary cyclones formed by connecting taper portion 41a formed in the outer container 21, and the cylindrical part 51a formed in the cover 50. Each of the secondary cyclones 40 is located at a selected angle chambers 41 of the secondary cyclones, respectively.

The upper part of the primary cyclone 30 and the secondary cyclones 40 is closed by a cover 50. Cover 50 includes a channel 51 for guiding the flow direction of the air leaving the primary cyclone 30, so that the air is evenly distributed in the many secondary cyclones 40 along the channel 51 to the flow direction, and through the outlet 44 through which air comes out, cleaned of contaminants by means of a secondary cyclones 40.

After passing through the air intake hole 11 formed on the lower side of the housing 20 of the device and communicates with the primary cyclone 30, the air forms an air circulation flow in the primary cyclone 30 when passing through with oralny channel 11a. Air circulation flow circulates between the outer peripheral surface of the primary cyclone 30 and the dividing wall 32, so that contaminants are separated from the air by centrifugal force of the air circulation flow and collected in the first dust collection vessel 33. Then the air is purified from contaminant particles by the primary cyclone 30, passes into the chamber 31 of the primary cyclone through the outlet hole 31a formed in the lower part of the chamber 31 of the primary cyclone, and then goes up.

Figure 3 depicts a rear view illustrating the cover 50 with the channel 51 to the flow direction and the outlet 44 of the secondary cyclones 40 formed in them.

As shown in figure 3, the cover 50 includes a distribution portion 52, the protruding downward from its center, for distribution of the air leaving the chamber 31 of the primary cyclone in all directions. While the channels 51 to the flow direction in the cover 50 to provide uniform air distribution, divided by the distribution part 52 into the corresponding secondary cyclones 40. In the cover 50 each channel 51 to the flow direction gradually decreases in cross-sectional area in the direction corresponding to the secondary cyclone 40 and directs the air to the inner peripheral surface cilindric the Russian part 51a, which is part of each secondary cyclone 40. As a result, the air is directed to the inner peripheral surface of each cylindrical part 51a through the corresponding channel 51 for flow direction and rotates along the inner peripheral surface of the cylindrical part 51a. Thus, some air escapes through the exhaust port 44, while the rest gradually moves downward and passes into a corresponding tapered portion 41a.

In the conical part 41a air goes down when circulating along the inner peripheral surface of the tapered portion 41a, so that the particles contained in the air, fall and accumulate in the second dust collection tank 42. Then the air again purified from contaminant particles, passes up and out through the outlet opening 44 of the secondary cyclones 40 formed in the cover 50.

The outlet 44 of each secondary cyclone 40 contains the partition 60 to reduce the circulation of the air circulation flow, which exits through the outlet 44 in the corresponding chamber 41 of the secondary cyclone, thus reducing noise generated in each discharge port 44.

As shown in figure 3, the partition wall 60 is located in the direction of the intersection of air that prog is the CIO at the outlet 44 through the channel 51 to the flow direction, formed in the cover 50. The partition 60 is located in a perpendicular direction relative to the incoming air. Thus, many of the partitions 60 are located in the circumferential direction around the junction portion 52 or the primary cyclone 30 when the separation of the respective exhaust holes 44.

Partitions 60 are, as described above, to prevent reduction in the efficiency of separation of contaminants through the secondary cyclones 40, which may be caused due to other installation positions of the partitions 60.

The speed of air circulation flow induced in each of the cylindrical part 51a through the appropriate channel 51 to the flow direction, the highest on the outer part of the cylindrical part 51a, providing, thus, a high separation efficiency particulate contaminants.

If each partition 60 is parallel to the airflow at the outlet 44 of each secondary cyclone 40, the air circulation flow is blocked by the partition walls 60, when the air circulation flow has the highest speed, thus reducing the separation efficiency of pollutants, regardless of the software noise reduction.

When the partition wall 60 is located in the outlet 44, he shall divides in half cross-section of the outlet 44. The partition 60 is located in the outlet 44 and has a predetermined height from the lower end of the outlet 44. Consequently, it is possible to avoid the circulation of the air circulation flow in the outlet 44.

Figure 4 depicts a curve showing the effect of noise reduction obtained at the location of the partitions 60 in the discharge ports in accordance with the embodiment.

Figa shows the noise level from the exhaust holes 44 of the secondary cyclones 40. It can be understood that when the partitions 60, described above, are located in the discharge ports 44, the noise level is greatly reduced.

In addition, as shown in figure 5, the outlet 44 of each secondary cyclone 40 may be provided with guide 45 air to direct air coming up through the outlet 44 of the secondary cyclone 40 in the direction of the air outlet 12.

Each rail 45 air is designed so that it is facing the air outlet 12. Guides 45 air change air flow coming up through the outlet opening 44 of the secondary cyclones 40 in the direction of the air outlet 12 formed on one side of the housing 20 of the device, thus preventing the formation of noise due to stolknovenii who eat air, exiting through the outlet opening 44, with the top cover 13 cyclone device 10. In addition, you can reduce the pressure loss, which may occur as a result of collision with the top cover 13, while the air exits through the vent hole 12 after passing through the outlet opening 44.

Many secondary cyclones 40 are arranged in the circumferential direction on the housing 20 of the device. Cyclone device 10 includes a guide plate 46 to prevent disturbing influence of the air coming through the outlet opening of many of the secondary cyclones 40 arranged in the circumferential direction on the device, while providing a smooth air flow towards the air outlet 12.

The guide plate 46 is positioned in such a way that one side facing the air outlet 12, and the other side facing in the opposite direction. With the help of the guide plate 46 located thus, it is possible to prevent the unwanted effects of air coming through the exhaust openings located opposite each other relative to the guide plate 46, and to provide a smooth air flow towards the air outlet 12.

The guide plate 46 is formed on the top cover 13. Nab is alausa plate 46 is formed as one unit with the top cover 13 by means of injection molding.

As can be seen from this description, cyclone vacuum cleaner in accordance with the present invention contains partitions that are located in the discharge holes of the secondary cyclones, reducing noise generated in the discharge ports.

In addition, each of the outlet guide contains air, thus reducing noise and pressure loss produced by the collision of air coming through the discharge holes of the secondary cyclones, with the top cover of the cyclone device.

In addition, the cyclone device comprises a guide plate, thus ensuring smooth flow of air coming through the vent hole.
