DETAILED DESCRIPTION of TYPICAL embodiments

Described in more detail below, some embodiments of the present invention with reference to the accompanying drawings.

In the description below, the same elements are the same notation elements even in different drawings. The objects specified in the description, such as detailed construction and elements are provided only to facilitate a comprehensive understanding of the invention. Thus, it is obvious that this invention can be made without specifying these objects. Also not listed under the one description of known functions or constructions, since the presence of excessive detail would confuse the invention.

Refer to figures 1 and 2, which shows the multi-cyclone device made in accordance with a variant implementation of the present invention and containing the first catching site 10, the housing 20 of the cyclones and the receiver 70 of dirt.

First catching site 10 has a window 11 for suction air, a first outlet port 13 and the casing 12 and allocates pollutant particles large amount of air coming through the window 11, which communicates with the suction brush 110 (see figure 4).

The casing 12 forms a duct connecting the window 11 and 13, and has a configuration essentially rectangular pipes. The window 11 is made in the lower part of the outer wall 15 of the casing 12. The first outlet box 13 is made in the upper part of the inner wall 14 facing the outer wall 15 of the casing 12. The window 13 is located above the window 11 and at a specified distance from him. The first outlet port 13 is connected to the first suction box 31 of the housing 20 cyclones. In this particular embodiment, the casing 12 is made in the shape of a rectangular tube. However, this option is provided only as examples, and therefore, experts in this field it is clear that the housing 12 can have any shape.

For efficient extraction of contaminants from the air passing through the first catching site 10, PR is doctitle case on the inner side of the casing 12 has a guide 16 and the wall 17. In this implementation of the air coming through the window 11 for suction air, allocates pollutant particles are relatively large, and the air pollutant particles small size can be discharged through the first outlet port 13. Guide 16 is made so that the air from the window 11 collides with the inner wall 14 of the casing 12, and then is emitted through the window 13. The shape of the guide 16 may be attached in various ways, provided that the incoming air may collide with the inner wall 14 of the casing 12. However, it is preferable that the guide 16 had the arcuate configuration of a given radius of curvature, and its front end 16A located below the window 13. In addition, the front end 16A of the guide 16 is located at a given distance from the inner wall 14 of the casing 12 so that the incoming air can pass through the window 13. The front end 16A of the guide 16 may have a linear configuration, although it is preferable to perform the front end 16A concave with a specific curvature radius (figure 4).

The partition 17 is located between the window 11 and the inner wall 14 of the casing 12. The upper end 17A of the partition 17 is located below the height of the front end 16A of the guide 16. Guide 16 is held against the inner wall 14 by a partition 17 so that the front end 16A napravlyayus is located against the inner wall closer than the upper end 17A of the partition. The distance between the partition 17 and the guide 16 are set so that the entrapped particles can move to the inner wall 14 of the casing 12, not lingering on the partition 17. The partition 17 prevents the window 11 passed in the opposite direction pollutant particles are captured and drawn between the partition and the inner wall 14 when they collide with the inner wall 14 of the casing 12. In other words, between the partition 17 and the inner wall 14 of the casing 12 is formed a space 18, which serves as the first catching debris chamber in which trap particles of large size (see figure 3).

In the example above, the first detecting node 10 are shown to illustrate the allocation of polluting particles of large size using gravity and inertia. However, although it is not shown, particles of large size at first capture node 10 can also optionally be selected using the filter.

In accordance with figure 2 and 3, the housing 20 contains a second cyclones cyclone 30, a third cyclone 40, the first cover 50 and the second cover 60.

The second cyclone 30 is designed to discharge air contaminants are medium in size and is located approximately in the center of the housing 2 cyclones. The second cyclone 30 has a first suction box 31, the inner wall 33 of the housing element 32, the guide thread, and lattice element 34.

The window 31 is communicated with the first outlet box 13 of the first detecting node 10 and directs the air released through the window 13, the second cyclone 30. In this particular embodiment, the window 13 and 31 are adjacent to each other. The inner wall 33 of the housing forms a space in which inverted the air twisted and which also separates the second cyclone 30 from the third cyclone 40. The element 32, the guide drawn in air from the first suction box 31 with its twisting, installed on the upper part of the second cyclone 30 in the center of the housing 20 cyclones. In the center of the element 32 connecting tube 36, which creates a channel through which the air inside the second cyclone 30, passes to the third cyclone 40. In the surface lattice element 34 has a series of holes 34a to allow air pollutant particles small size to the third cyclone 40 and at the same time preventing the passage of contaminant particles of average size from the second cyclone 30. In addition, at the lower end of the grid element 34 is made skirt 35, preventing the passage of selected contaminants in the opposite direction.

A third cyclone 40 is designed to discharge contaminants mA is th size of air, coming from the second cyclone 30. More specifically, the third cyclone 40 contains third cyclones 40, which are arranged around the second cyclone 30 and each of which is communicated with the second cyclone 30 through the first cover 50. Each third cyclone 40 is made in the form of a cone, tapering from top to bottom. Third cyclones 40 surrounded by an outer wall 45 of the housing. Each of third cyclones 40 at the lower end has a hole 41 for dirt.

The first cover 50 connects the second and third cyclones 30 and 40. The first cover 50 is made on the upper part of the second and third cyclones 30 and 40. The first cover 50 includes a centrifugal channels 52 and the discharge tube 51, which number corresponds to the number of third cyclones 40. Between the first cover 50 and third cyclones 40 posted by strip 53, designed to prevent air leaks. Centrifugal channels 52 to cause twisting of the air coming through the connecting tube 36 of the second cyclone 30 and send it to on the top of inputs 52 of third cyclones 40. The discharge tube 51 create channels through which free from the polluted air of third cyclones 40 can be thrown out.

The second cover 60 has an outlet 61 for air and shaped so that it covers the upper portion of the first cover 50. As shown in figure 5, in which the stop multi-cyclone device 1 in the vacuum cleaner 100 outlet 61 communicates with the node 140 of the motor of the vacuum cleaner 100.

The receiver 70 of the impurities is performed on the lower end of the housing 20 cyclones and is intended for collection of particles, selected in the second and third cyclones 30 and 40. The receiver 70 dirt includes a housing 71 and the separation element 73. The separation element 73 is tilted at an angle to the inner periphery of the housing 71 of the receiver and is designed to divide the internal space of the housing 71 on the second and third catching chambers 72 and 74. The second detecting chamber 72 receives particles of average size from the second cyclone 30, and the third catching chamber 74 receives pollutant particles small size of third cyclones 40. Since usually the number of contaminant particles of medium size exceeds the number of contaminant particles of small size, it is preferable that the size of the second detecting chamber 72 exceeded the size of the third detecting chamber 74. In addition, as shown in figure 2, the separation element 73 has a shape similar to a truncated cone. The form of the separation element 73, which is close to a truncated cone, is preferred because it allows more efficient to create the size of the second detecting chamber 72, exceeding the amount of third-catching camera 74, and also to empty the receiver 70, containing the second detecting chamber 72.

Despite the fact that OPI the data above multi-cyclone device 1 has a housing 20 cyclones, contains one second cyclone 30 and a number of third cyclones 40, this option is provided only as an example, therefore, the number of second cyclones 30 can be increased to two, three or more than three, depending on the shape or size of the vacuum cleaner 100.

Below with reference to figure 1-3 shows the description of the operation of multi-cyclone device having the above structure.

When creating a suction efforts node 140 of the engine (figure 5) polluted air is drawn into the first detecting node 10 through the window 11 to suction air. Inverted air contains particles of various sizes. The air drawn into the casing 12 of the first detecting node 10 through the window 11, is moved along the guide 16 to the inner wall 14. During the move, the air collides with the inner wall 14 of the casing 12, because the path has changed. As a result of the collision of particles of relatively large size fall into the space 18, and the particles of medium and/or small size are ejected into the first outlet port 13 along with manufactured by air. Drop-down particles accumulate in the first detecting chamber 18 between the wall 17 and the inner wall 14 of the casing 12. The partition 17 prevents the reverse flow of contaminating particles collected in the first capture to the extent 18, to the window 11.

The air from the window 13, still containing pollutant particles are mostly medium/small size, enters the housing 20 cyclones through the first suction box 31. The air passes through the window 31, and then is moved to the second cyclone 30 and element 32. Due to the spiral configuration (not shown) of the element 32, the air entering the second cyclone 30 begins to curl. The result is that particles of medium size are allocated from the air by centrifugal force and fall. The selected particles are accumulated in the second detecting chamber 72 of the receiver 70 of contamination. However, particles of small size are still fond of air and thrown together with him through the grating element 34. At this time, the skirt 35 prevents the passage of contaminant particles of medium size in the opposite direction.

After passing through the holes 34a lattice element 34, the air flows through the connecting tube 36 and faces the first cover 50. After the collision with the first cover 50 air enters third cyclones 40 located radially centrifugal passages 52. When entering the third cyclones 40 air twists, free from contaminating particles of small size due to centrifugal force. As a result of this free of pollution air is discharged through the discharge tube 51 to the upper side of the first cover 50. Particles of small size are accumulated in the third catching chamber 74 of the receiver 70 through the opening 41 located at the lower end of the third cyclone 40.

Free from the contamination of the air discharged from the third cyclone 40 through a series of exhaust pipes 51 of the first cover 50 to the upper side of the first cover 50, and then moves along the second cover 60 and is thrown through the window 61 for venting. Released from the outlet port 61 of the air drawn into the motor unit 140 (figure 5) and is expelled from the vacuum cleaner 100 to the outside (figure 5).

Using the proposed multi-cyclone device 1 made in accordance with the above option, particles of large size are separated at the first stage by passing air through the first catching site 10, particles of medium size are separated at the second stage during the passage of air through the second cyclone 30 and polluting particles of small size are separated in the third stage when the passage of air through the third cyclones 40. The result is the ability to carry out effective cleaning contaminant particles. In other words, the multi-cyclone device 1 made in accordance with the above-described variant of the present invention may implement a three-step purification from contaminating particles and therefore especial high efficiency of their capture. In the above description, the terms "large", "medium size" and "small size" used to describe coming into the multi-cyclone device 1 of polluting particles in accordance with their relative size and weight.

Below with reference to figure 5 describes a sample run of the vacuum cleaner 100 with the above multi-cyclone device 1.

In accordance with figure 5 of the vacuum cleaner 100 includes the suction brush 110, which pulls particles, the block 120 extension pipe connecting the suction brush 110 with the housing 130 of the vacuum cleaner, and the housing 130, divided by the camera 131 for contamination and the camera 132 to the engine.

The suction brush 110 has a window for absorption of contaminants (not shown)designed to retract from the surface being cleaned of contaminating particles of different size.

The block 120 includes an extension tube 121 that is connected with the brush 110, and a flexible hose 122 connected at one end to the tube 121 and the other end into the multi-cyclone unit 1 housing 130 of the vacuum cleaner.

More specifically, the multi-cyclone device 1 is installed in the chamber 131 for contamination of the body 130 of the vacuum cleaner and is intended for the separation and collection of particles from the incoming air. Multi-cyclone device 1 includes the first catch is the second node 10, the housing 20 cyclones and the receiver 70 of contamination. With a flexible hose 122 of the unit 120 of the extension tubes will be informed of the window 11 to the suction air of the first catching site 10. Therefore, the air drawing through the suction brush 110 is fed through the block 120 of the extension tubes in the first catching site 10. This node 10 selects from the air and catches particles of large size. The housing 20 contains a second cyclones cyclone 30 and a third cyclone 40, designed for sequential removal of pollutant particles small and medium size from the air that is supplied from the first detecting node 10. The receiver 70 includes a second detecting chamber 72 and the third catching chamber 74 (Fig 3)intended for the separation and collection of particles of small and medium size allocated in the second and third cyclones 30 and 40. Detailed description of the design of the multi-cyclone device 1 has already been described above, so for brevity here it is not given.

Node 140 is placed in the chamber 132 to the motor housing 130 of the vacuum cleaner and is designed to create a suction effort to draw contaminated air from the suction brush 110. Node 140 includes a motor 142, the impeller (not shown)rotated by a motor 142, and the diffuser 141, which directs the air drawn through krill is atki, to the motor 142.

Therefore, when the rotation of the motor 142 of the vacuum cleaner 100 having the above structure, the impeller makes rotation and therefore creates a suction force. Due to the suction created the efforts of particles of different sizes contained in the air drawn in through the window to suction dirt brush 110. Entrapped air and particles through an extension tube 121 and the flexible hose 122 of the unit 120 receives the window 11 multi-cyclone device 1. When entering the window 11, the air passes through the first detecting unit 10, the second cyclone 30 and a third cyclone 40, shaking at each stage of pollutant particles of large size, medium size and small size. Therefore, through the window 61 for venting to the node 140 engine is available free from polluted air. Pollutant particles are large, medium and small size are sequentially deleted the first detecting node 10, the second cyclone 30 and the third cyclone 40, are received respectively in the first, second and third detecting chambers 18, 72, 74 (Fig 3). Explanation consistent separation and capture of contaminants in accordance with their size was above, so for brevity it will not be repeated here.

Clean air, from which when it passes through the multi-cyclone mouth is eusto 1 removes contaminating particles, passes through the impeller and the diffuser 141 node 140 of the engine and is discharged from the housing 130 of the vacuum cleaner out.
