The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates to improvements in vacuum cleaners or associated with vacuum cleaners and in particular, relates to improvements relating to vacuum suction nozzles for vacuum cleaners. More specifically, the present invention provides improvements relating to the shaking of the surfaces to be treated, and/or the air flow in the suction nozzle of a vacuum cleaner.

PRIOR art

The cleaner includes a suction nozzle in order to localize and limit the size of the suction adjacent to the surface to be cleaned. The suction nozzle includes a peripheral surface or the peripheral seal to form a suction nozzle seal against the surface. Thus, the camera system in the suction nozzle pulls debris and dust from the surface due to the suction power generated by the generating tool suction vacuum cleaner.

If the suction nozzle creates a tight seal with the surface, the user will not be able to manually move the cleaning nozzle over the surface to be cleaned. Accordingly, vacuum cleaning attachments need in the areas of air leaks or air jets. Data air is nye nozzles create a flow of air from the external atmosphere into the suction chamber in the suction nozzle. Thus, air flows from the suction nozzle through the connecting tube or channel in the dust chamber of the vacuum cleaner. Then the air exits from the chamber back into the atmosphere.

The air nozzles in the suction nozzle is required, but actually waste the energy absorption. Covered with carpet or other uneven surfaces air nozzles may occur naturally due to the inability of the education of the peripheral seal cleaning nozzles airtight seal with the surface. However, on a smooth hard surface cleaning nozzle can easily create essentially airtight seal and as a consequence require air jets, or discontinuous peripheral surface (for example, the brush seal may be placed around the cleaning nozzle and to act as an air nozzles and provide unmetered air into the cleaning nozzle, which is located approximately in one plane with the surface being cleaned.

Vacuum cleaners and, in particular, upright vacuum cleaners generally include shaking the device in the cleaning nozzle. Shake the device to activate the brush plate, which contains a brush mounted on a rotating cylinder so that the brush shook and released dirt and debris on top of the spine and especially the carpet surface. The cylinder can be actuated to rotate or specially designed electric motor, electric motor, in common with the suction fan of the vacuum cleaner, or it may operate by an air stream of a vacuum cleaner. Accordingly, when using a shaking device consumes power and, consequently, energy is used.

If the brush plate has a specially designed motor, it increases the cost of the vacuum cleaner. In addition, the motor may be damaged and thereby increases the likelihood of problems arising in the vacuum cleaner. If the brush plate is driven by the fan motor, it requires a gear drive mechanism for actuating the brush plate. Again, this increases the cost of the vacuum cleaner, and also increases the likelihood of problems/issues. Similarly, if the brush plate is driven by an air stream of a vacuum cleaner, it again requires additional devices, which increases costs and the likelihood of breakage. In addition, this also reduces the suction power generated by the cleaning nozzle, as part of this suction power will be lost due to the energy required to actuate the brush plate.

Shaking carpet is o fiber is most preferable for the cleaning efficiency of the vacuum cleaner due to the effectiveness of the steps in the release of dust and debris from the carpet fibers, to which they can adhere.

The purpose of the present invention is to solve at least one problem associated with prior art mentioned or not in this application.

DESCRIPTION of the PREFERRED OPTION IMPLEMENTATION

The following example will be described a specific variant, the alleged authors of the invention. In the following description outlines a number of specific details in order to provide a comprehensive understanding. However, specialists in the art should understand that the present invention can be implemented in practice, not limited to specific data items. In other instances, well known methods and structures have not been described in detail in order without needing to complicate the understanding of the description.

As shown in figures 1 to 4, the device for vacuum cleaner 10 includes a cleaning nozzle or the suction nozzle 12, which includes the suction chamber 14 to create and contain a region of relatively low pressure adjacent to the surface 16 to be treated. As explained earlier, the suction nozzle 12 includes a peripheral element 18, which is made with possibility of accommodation close to the surface 16. Peripheral element 18 is necessary to reductivity effective suction chamber 14. However, on certain surfaces of the peripheral element 18 can form a very effective seal that prevents manual movement of the suction nozzle 12 to the surface 16. Accordingly, the suction nozzle 12 required tools air intake (air nozzles 20). In the embodiment shown in figures 1 to 4, the suction nozzle 12 includes lateral nozzles 19, which provide the possibility of entering into the suction chamber 14 a certain amount of air. This air flow is essentially in the same plane with the surface 16 to be treated. The suction nozzle 12 includes a holder 50 of the brush of the canvas, which is made with the possibility of holding a brush blade to facilitate cleaning of the surface 16 and to aid in the lifting and removal of dust and debris. Suction nozzle also includes a rear wheel 52 and the front wheels 54 to allow easy movement of the suction nozzle 12 to the surface. In a preferred embodiment, the tool air inlet contain air nozzles 20, which create a vortex air flow 28, when the air passes through the air nozzles 20 into the suction nozzle 12. This vortex air flow 28 is designed to directions towards the surface 16 to be cleaned, and before naznachen to move (or penetration) in the surface 16, be cleaned. This vortex air flow is designed for shaking the surface 16 to be treated, and consequently to improve the efficiency of the vacuum cleaner 10. In an alternative embodiment, the air nozzles contain a means of inducing air flow, which can provide essentially the mainly linear air flow through the suction nozzle 12 into the suction chamber 14. For example, air nozzles 20 can include tubular sections, which induce a substantially linear air flow into the suction chamber 14.

As shown in figa, fig.11b and figs, in preferred versions of the air flow creates a cyclone aimed towards top 30 top 30 is localized below the upper level of the cleaning surface 16. For example, the top 30 of the vortex air stream 28 is localized inside the carpet fibers so that the air stream 28 was dissolved in carpet fibers, and is located with the option of raising and shearing dirt, debris and dust inside the carpet. Accordingly, the vortex nozzles 20 perform a dual function of providing the necessary air nozzles to the suction nozzle 12, and fulfilling at the same time the function of the shaking device surface.

The suction nozzle 12 including the AET many vortex of air nozzles 20, which are shown in figure 5-10.

Vortex air nozzles 20 are arranged at least in one group, and in the preferred embodiment, the suction nozzle 12 includes two linear groups vortex of air nozzles 20. The suction nozzle 12 includes a first linear group of vortex air nozzles 20A, which runs across the width of the suction nozzle 12, and the second line group of the second vortex air nozzles 20b, which runs across the width of the suction nozzle 12. The second group is localized behind the first group. The second vortex air nozzles 22A in the second group linearly displaced from the first vortex of air nozzles located in the first group, as shown in figure 2 and figure 4. This bias configuration increases the surface area that is subjected to shaking through cyclones 28 created by the vortex of air nozzles 20, for example suction nozzle 12, as a rule, is moved forward and backward, and as cyclones shifted, it reduces the likelihood that the surface area of 16 will not be subjected to direct the shaking.

Groups of vortex nozzles 20 can be located around the center of the connecting pipe 34, as shown in figure 10. Alternatively, the first group of the first vortex air nozzles 20A can the t to be continuous, whereas the second group of the second vortex air nozzles 20b may be located on each side of the pipe 34, as shown in figure 4. Each vortex air jet 20 includes a chamber 22 having a surface 24 with the shape of a truncated cone, and is directed tangentially hole 26 for the air intake, as shown in figa, and fig.11b, and 11C. Each vortex air jet 20 includes an exhaust hole 27, which is located in the center at the lower end and directs the air flow out into the suction chamber 14. When using the air enters through directed tangentially hole 26 for air intake and air drawn through the nozzle 20 by moving around the surface 24 with the shape of a truncated cone, generally in the form of a spiral or helical path 28, as shown in figs. Accordingly, the air flows down along a helical path with decreasing diameter so that the air stream is accelerated and moves in the direction of the top 30 (shown schematically in figs). It is assumed that the air in the top 30 picks up and pulls the carpet fibers to lift and release the dust and debris and then the air moves through the suction chamber 14 and through the outlet 32, at the same time also taking away dust and debris. As with conventional vacuum cleaners, the air flow it enables the speaker dust and debris, then moves through the pipe 34 and into the dust collection chamber, where they can accumulate dust and debris. Dust Luggage can be a conventional system or may be a vortex system. As soon as the dust and debris, or at least a considerable part of them are deposited, the air then flows back into the external atmosphere.

The suction chamber 14 is limited to the upper wall 36 and at least one peripheral wall 38. The outlet 27 of the vortex of air nozzles 20 are located on the top wall 36. In the preferred embodiment, as shown in figure 2, the suction chamber 14 has an essentially H-shaped, so that the first group of vortex air nozzles 20A is located in the first linear section of the suction chamber 14, and the second group of vortex air nozzles 20b is located in the second linear section of the suction chamber, and the two sections are joined in the center, where is located the outlet 32 to the outlet 34. This reduces the surface area of the effective suction chamber 14 and thereby relatively reduce the suction power. As shown in figure 5, the top wall 36 of the suction chamber 14 is flat and is in use in the same plane with the surface 16 to be treated. In addition, the suction chamber 14 may also include auxiliary is atelinae air nozzles 19, which are located around the peripheral wall 38 of the suction chamber 14. In the preferred embodiment, as shown in figure 1-5, the outlet 27 of the vortex of air nozzles 20 are flush with the upper wall 36 of the suction chamber 14.

The suction nozzle 12 includes two main air passage, both of which are used for suction of the Central hole 32. On each air passage has a series of vortex cones, which end up inside the air passage. Between each air passage has a brush for extra help in shaking the floor. Nozzle for floor also has a side nozzles 19 to facilitate stenosoma/lateral grip. Suction nozzle for a floor also includes a flexible sleeve connecting the main bore 32 and the rotary sleeve. This provides flexibility and improved seal the air path. The main nozzle for a vacuum cleaner is connected to the suction nozzle 12 by means of a sliding bracket 56 of the mounting tube, and the suction nozzle 12 includes a rotary sleeve 58 and the pivot joint 60. The suction nozzle 12 and contains constructed from the top of the leaf 62 and the lower sash 64.

You can see that the present invention provides an improved cleaning attachment 12 for a vacuum cleaner 10, which includes a tool vstra the-air traffic management, which is done efficiently and without any moving parts, which could increase the risk of breakage. The present invention achieves this advantage, being at the same time energy-efficient. You should understand that the present invention may be included in a cleaning nozzle having a conventional shaking the device with the brush plate, so that the action of the vortex nozzles 20 will complement the action of the brush plate.

As shown in Fig-15, a second variant implementation of the suction nozzle 12 to the vacuum cleaner 10 includes a first group of the first vortex air nozzles 20A and the second group of the second vortex air nozzles 20b. The outlet 27 of each vortex jet contain protruding section 70, which protrudes downward from the upper wall 36 of the suction chamber 14. Data exposed areas 70 effective in forming processes, and in this embodiment, the processes are celesoobraznym, the top 71 of tears is located in the direction of the outlet 32. This form of tears helps to improve the aerodynamic properties of the suction nozzle 12 and prevents or eliminates the buildup and accumulation of any debris on the stagnation air side shoots. It also allows you to finish the whirl closer to the surface 16 of the floor and because it is about to create more shaking.

On figa-16d shows a third embodiment of the suction head 12 to a vacuum cleaner. The outlet 27 of the vortex air nozzles 20A, 20b are located on the section 74 of the raised plate, which protrudes downward from the upper wall 36 of the suction chamber 14. The purpose of the plate 74 is to prevent the buildup of debris and create a passage for clean air in the suction chamber 14.

The fourth embodiment of the suction nozzle 12 to the vacuum cleaner 10 is shown in figa-17d. In this embodiment, the suction nozzle 12 includes a first group of the first vortex air nozzles 20A, which are directed and curved back to the suction nozzle 12. In addition, the suction nozzle 12 includes a second group of the second vortex air nozzles 20b, which are directed forward and bent down on the suction nozzle 12. This curved design provides a single location of the vertices of vortex air nozzles 20A, 20b in both groups and thereby helps to ensure uniform shaking the surface to be cleaned.

The fifth embodiment of the suction nozzle 12 to the vacuum cleaner 10 is shown in figa-18b. In this embodiment, the vortex of air nozzles 20 are raised areas 76, which pass down from the top wall 36 of the suction chamber 14. Protruding areas 76 or otro the TCI are generally round and ensure the completion of the movement of the vortex closer to the surface 16 of the floor and thereby create more shaking.

Sixth variant of implementation of the present invention shown in figa-19d. In this embodiment, the outlet port 27 of the vortex air nozzles 20A, 20b are located flush with the upper wall 36 of the suction chamber 14. The purpose of this configuration is to avoid obstacles or debris and dirt inside the suction chamber 14, which can build up dirt and debris and to reduce the efficiency of the vacuum cleaner 10.

The seventh embodiment of the suction nozzle 12 to the vacuum cleaner 10 is shown in figa-20d. In this embodiment, the suction nozzle 12 includes a first group of the first vortex air nozzles 20A, a second group of the second vortex air nozzles 20b, and the third group of the third vortex of air nozzles 20. The third group of the vortex of air nozzles 20 is located between the first group of vortex air nozzles 20A and the second group of the second vortex air nozzles 20b. In addition, the first group of the first vortex air nozzles 20A as a whole is bent back so that the top of the cyclones generated by the first vortex air nozzles 20A, in General, coincide with the vertices of the cyclone, which creates the third group of the third vortex of air nozzles 20. Similarly, the second vortex air nozzles 20b in the second group bent down and forward so the m way the top of the cyclones generated in the second vortex air nozzles 20b, coincide with the vertices of the cyclones that are generated as the first vortex air nozzles 20A and third vortex air nozzles 20. You can see that each of the vortex air nozzles 20A, 20b, 20C is displaced in the lateral direction along the suction nozzle in order to provide a complete linear arrangement of the vertices for shaking the surface to be cleaned.

Eighth variant of implementation of the present invention shown in figa-21d. In this embodiment, the upper wall 36 of the suction nozzle 14 is curved downward from the Central position. In particular, the upper wall of the suction chamber 14 contains a first lateral section 76, which passes down from the Central outlet 32 to the first side and the second lateral section 78 passes downwards from the Central outlet 32 to the second side. In this embodiment, the vortex air jet 20 contains all the appendages that protrude downward from the upper wall 36. In particular, as the location of the shoots farther away from the Central outlet 32, protruding distance decreases up until the outlet 27 of the vortex air nozzles 20A, 20b located on the side vsasyvauschie the nozzle 12, will not be flush with the upper wall 36 of the suction chamber 14. Accordingly, the whirl ends inside the air passage, and the processes of the support end of the vortex cone. This allows the end of the movement of the vortex closer to the floor surface and thus create more shaking.

The ninth embodiment of the suction nozzle 12 for use with a vacuum cleaner 10 shown in figa-22d. As described previously, the upper wall 36 of the suction chamber 14 is bent downward from a Central location. However, in this embodiment, the vortex air nozzles 20A, 20b do not include shoots, but the outlet 27 of the vortex air nozzles 20A, 20b are essentially flush with the two sections 76, 78 of the top wall 36 of the suction chamber 14. Accordingly, the swirling motion ends at the same level with the air passage so that there are no obstacles to build on them dirt and debris.

The tenth embodiment of the suction nozzle 12 to the vacuum cleaner 10 is shown in figa-23d. In this embodiment, the suction nozzle 12 includes additional linear air nozzles 80 between the vortex motion. In particular, linear air nozzles 80 includes an opening 82 for the air intake where the air from the atmosphere is drawn into the suction chamber 14. Lina is by air jets 80 contain outlet 84 for air, through which air is introduced into the suction chamber 14.
