Description

BACKGROUND OF THE INVENTION

1. The scope of the invention

The present invention relates to a vacuum cleaner, and more specifically, to a vacuum cleaner containing a cyclone dust collector for separating and collecting debris from air containing debris, under the action of a centrifugal force generated by creating a vortex of air, and a removable additional filter placed in the vacuum cleaner, the filter can be cleaned and used again.

2. Description of the prior art

In US patent No. 6195835, the rights to which belong to the assignee of this application, describes a vacuum cleaner containing a cyclone dust collector.

In figures 1 and 2 schematically shows the design of a vacuum cleaner containing a cyclone dust collector according to US patent 6195835.

As can be seen from figure 1, in General, a vacuum cleaner having a cyclone dust collector includes a housing 1, a suction channel 2 and a cyclone dust collector 10 located between the housing 1 and the extension tube 3 connected to the suction channel 2.

The housing 1 comprises a dust collecting compartment 5, in which, as a rule, a paper filter 4 and an engine compartment (not shown) are located. The cover 6 is located on the upper part of the dust compartment 5 and can move, opening and closing when turning around an axis. The extension tube 3 is connected to the handle 7 and the flexible hose 8. One end of the flexible hose 8 is attached to the cover 6.

As shown in FIG. 2, the cyclone dust collector 10 comprises a cyclone body 20, a dust collector, and a grill assembly 40. The cyclone body 20 includes a first connecting pipe 21 connected to an extension pipe Behind the suction channel, a second connecting pipe 22 connected to an extension pipe 3b of the vacuum cleaner body , the air supply channel 23 communicating with the first connecting pipe 21, and the air outflow channel 24 communicating with the second connecting pipe 22. In the cyclone body 20, air containing debris is drawn through the air supply channel 23 air forming a whirlwind.

The dust collector 30 is removably connected to the cyclone body 20 and receives debris separated from the air by the centrifugal force of the vortex air flow in the cyclone body 20.

The grill assembly 40 is located in the air outflow duct 24 of the cyclone body 20 to prevent the collection of garbage from returning through the air outflow duct 24. The lattice assembly 40 includes a lattice body 41, a plurality of small holes 42 made on the outer surface of the lattice body 41 to form a passage to the air outflow channel 24, and a plate 43 for preventing debris backward movement having a conical shape and made on the lower end of the lattice body 41.

In a conventional vacuum cleaner with a cyclone dust collector of the above construction, the garbage-containing air is drawn in by the suction force generated in the suction channel 2 of the vacuum cleaner into the cyclone body 20 in a tangential direction through the first connecting pipe 21 and through the air supply channel 23. The drawn-in air moves downward in the cyclone body 20, forming a swirling air flow (indicated in Fig. 2 by a solid line with an arrow). During this movement, the debris is separated from the air by the centrifugal force of the vortex of air colliding with the grate, and is collected in the dust collector 30.

When the air stream reaches the bottom of the dust collector 30, the air begins to move in the cyclone body 20 in the opposite direction, that is, up. Then the air passes through the small openings 42 of the grating unit 40, the air outflow channel 24 and the second connecting pipe 22, and then is discharged into the vacuum cleaner body 1 (as shown in FIG. 2 by a dashed line with an arrow). Part of the debris in the upward flow of air changes direction thanks to the plate 43 to prevent the reverse movement of debris and, thus, returns to the swirling air stream. Some part of the debris, which is nevertheless carried away by the upward flow of air, passing the plate 43 to prevent the reverse movement of air, is filtered out in the small holes 42 of the grating unit 40 when the air passes through the small holes 42, and the filtered debris enters the air vortex stream.

The remaining part of the debris, which was not removed even when passing through the small openings 42, is discharged through the small openings 42 and the air outflow channel 24. This remaining debris is then filtered by an additional filter, a paper filter 4 in the housing 1 of the vacuum cleaner, while clean air is discharged out of the vacuum cleaner through the engine compartment (not shown).

In a conventional vacuum cleaner with a cyclone dust collector, due to the fact that the debris contained in the air drawn in through the suction channel 2 is filtered by the cyclone dust collector 10 located on the extension tube 3, the amount of debris passing through the paper filter 4 in the dust collecting compartment 5 is reduced. Accordingly, the life of the paper filter 4 is increased. But even under these conditions, paper filter 4 is an expendable item, since the user is still forced to pay for replaceable paper filters that are discarded after use.

In addition, a conventional vacuum cleaner with a cyclone dust collector has a dust collection compartment, which occupies a significant part in the vacuum cleaner body. Accordingly, the body of the vacuum cleaner becomes bulky and heavy, which causes inconvenience to the user.

From the useful moderation of the Russian Federation No. 18622, a vacuum cleaner is also known, comprising a housing having an engine compartment, a garbage compartment and a clutch with a filter; a cleaning nozzle in communication with the garbage compartment and adapted to make contact with the surface to be cleaned and expose it to a suction air stream to draw in trash; a cassette filter located in the garbage compartment and having a housing, a removable filter disposed therein for collecting garbage from the air stream, and a locking mechanism mounted on the housing and having a latch for interfacing with the filter clutch.

The known vacuum cleaner uses a cassette filter containing filtering elements in the form of plates, which must be constantly changed when dust accumulates in the filter. Thus, the design of the filter does not allow it to be maintained in working condition by cleaning it, without replacing the filter element, which increases operating costs. In addition, the design of the known filter does not provide the convenience and speed of cleaning.

SUMMARY OF THE INVENTION

The present invention is made to overcome the above problems that occur in known analogues. Accordingly, it is an object of the present invention to provide a vacuum cleaner having a reusable dust filter, that is, a washable dust filter, the use of which allows it to be maintained in working condition by cleaning it, which can be carried out conveniently and efficiently, without replacing the filter element, and thus reduce costs during repair and maintenance of the vacuum cleaner.

The above problems are solved due to the fact that in a vacuum cleaner containing a housing having a dust compartment and an engine compartment in communication with the dust compartment; a suction channel communicating with the cleaner body via an extension tube; a cyclone dust collector attached to an extension tube for separating and collecting debris from air containing debris under the action of centrifugal force and to create a vortex of air creating a centrifugal force; and a dust filter placed with the possibility of removal in the dust collection compartment of the vacuum cleaner body, for separating and collecting any debris not separated by a cyclone dust collector, having a structure that allows multiple use due to the possibility of removing collected debris from the dust filter and subsequent cleaning of the dust filter; and fixing means for fixing the dust filter in the mounting position in the dust compartment of the vacuum cleaner body, a cassette filter is used as a filter, comprising a housing including a filter for collecting debris from the air stream in the vacuum cleaner and a dust collector; a cover attached to the specified housing with the ability to move between open and closed position; and a handle combined with a locking mechanism mounted on said lid for engaging with said fixing means. Such a handle can be made in the form of a bucket handle.

The filter cover may include an inspection window through which you can monitor the state of garbage collection.

In a preferred embodiment of the invention, the locking means comprise guide grooves formed along opposite side walls of the dust compartment; semi-cylindrical locking recesses made at the respective ends of the guide grooves; and semi-cylindrical latches, which are made on opposite sides of the handle, the shape of which allows you to mate with the guide grooves and which are adapted to pass along the guide grooves and engage with the semi-cylindrical locking recesses.

The dust filter has a design that allows you to reuse it by removing and then cleaning it from collected garbage.

According to another aspect of the present invention, the vacuum cleaner comprises a housing having an engine compartment, a garbage compartment, and a filter clutch; a cleaning nozzle in communication with the garbage compartment and adapted to make contact with the surface to be cleaned and expose it to a suction air stream to draw in trash; a cassette filter located in the garbage compartment and having a housing, a removable filter therein for collecting garbage from the air stream, and a locking mechanism mounted on the housing and having a latch for interfacing with said filter clutch, the filter comprising a housing containing a filter for collecting garbage from the air stream in a vacuum cleaner and dust collector; a cover attached to the specified housing with the ability to move between open and closed position; and a handle combined with a locking mechanism mounted on said lid for engaging with said clutch in the cleaner body.

The clutch device with the filter may also have a guide groove ending in a recess, the shape of which corresponds to the shape of the latch, so that the latch can be placed in the recess. In this case, the dimensions of the guide groove can be selected so that the latch can be placed in the groove only with its longitudinal orientation, and the shape of the locking recess can be such that the latch can be rotated in the transverse position so as to fix the cartridge filter in the compartment for garbage.

The vacuum cleaner may further comprise a handle that is integral with the locking mechanism, so that the rotation of the handle causes a corresponding rotation of the latch when it is inserted into the locking recess.

In addition, the vacuum cleaner may have a viewing window on the housing that allows you to monitor the collection of garbage in a cassette filter.

A washable filter can be used as a filter, which allows you to reuse a cassette filter.

In yet another aspect of the invention, a cassette filter is provided that is adapted to be mounted in a collecting compartment of a vacuum cleaner and comprising a housing including a filter for collecting debris from an air stream in a vacuum cleaner and a dust collector; a lid attached to the housing with the possibility of moving between the open and closed position, and a handle combined with a locking mechanism and mounted on the lid for engaging with the mating device in the vacuum cleaner.

Detailed Description of a Preferred Implementation Example

As shown in figures 3 and 4, the vacuum cleaner according to the present invention includes a housing 1 of the vacuum cleaner, a suction channel 2, a dust collector 10 and a dust filter 300.

The vacuum cleaner housing 1 comprises a dust collection compartment 100 at the inlet of the flow and a compartment of the engine 200 at the outlet of the stream. For ease of description, the arrangement of the elements will be described with reference to one direction of air flow or suction force. For example, the dust collection compartment 100 is located upstream of the engine compartment 200, so that the compartment 100 can be considered to be in front of the engine compartment 200. The dust collection compartment 100 is limited to the front and rear walls 110 and 120 having openings 111 and 121 respectively formed therein. The dust filter 300 is removably housed in the dust chamber 100, and the engine 400 is housed in the engine compartment 200. The structure of the vacuum cleaner body 1 is similar to that of a conventional vacuum cleaner, however, as shown in FIG. 3, the vacuum cleaner body 1 according to the present invention is much smaller than the body conventional vacuum cleaner (see figure 1) due to the reduced size of the dust collection compartment 100. Due to the compactness of the dust collection compartment 100, the housing 1 of the vacuum cleaner is also compact and light in weight, and accordingly the vacuum cleaner becomes more convenient to use Operation and maintenance, especially when lifting and moving the housing 1.

The suction channel 2 is connected to the housing 1 of the vacuum cleaner. The extension tube 3 is connected to the handle 7 and the flexible hose 8. One end of the flexible hose 8 is connected to the hole 111 in the wall 110 of the housing 1 of the vacuum cleaner. After engine 400 is turned on, a strong intake air stream is created in the cleaning nozzle or in the suction channel 2 using a flexible hose 8 and extension tube 3.

As noted above in the description of known analogues, the cyclone dust collector 10 is attached to the extension tube 3, and debris 5 contained in the air drawn through the suction channel 2 is filtered in the cyclone dust collector 10. The design and operation of the cyclone dust collector 10 are similar to the construction and operation of a conventional cyclone dust collector.

In the housing 1 of the vacuum cleaner, a removable dust filter 300 is disposed in the dust compartment 100 for separating and collecting any debris that has not been separated and collected by the cyclone dust collector 10. According to the present invention, a reusable dust filter 300 of a cassette type is advantageous since after removing the collected debris, the filter 300 can be cleaned and returned to its place in the dust compartment 100 for next use.

As shown in figures 4 through 7, the cassette-type dust filter 300 includes a filter housing 310 and a handle 330. The filter housing 310 includes a filter 311 on the opposite side of the flow inlet and a dust chamber 312 in front of the filter 311. In other words, the filter 311 is attached to the back wall of the dust collecting chamber 312. The filter cover 320 is mounted to the filter housing 310 so that it can be moved with a loop 321 so as to rotate from the open to the closed position and vice versa with respect to the dust collecting chamber 312 of the filter housing 310. In the closed position, the lid 320 closes the chamber 312 and is essentially parallel to the filter 311. The shape of the cassette filter 300 with the lid 320 closed allows it to be inserted into the dust collection compartment 100. The filter 320 has an inlet 322 which, when the cassette filter 300 is installed in its operating position, aligned with the associated hole 111 in the front wall 110 of the dust collecting compartment 100. Accordingly, after air leaves the cyclone dust collector 10, air enters through the opening 110 and the inlet 322 into the dust collecting chamber 312 of the dust collecting filter ra 300, where any remaining debris is filtered out using a filter 311, and thus purified air is discharged out of the vacuum cleaner body 1 through the engine compartment 200. The filter cover 320 may also have an inspection window through which the user can control the amount of debris collected in the dust chamber 312.

The cassette filter 300 includes a handle 330 mounted on both sides of the filter cover 320 to rotate about an axis. The handle 330 can be rotated from the assembly position, in which the dust filter 300 is installed in the dust collection compartment 100 or removed from it, in a locked working position, in which the cassette filter 300 is in the installed state in the dust collection compartment 100.

To be able to use the cassette filter again after washing, the installation and removal of the filter 300 should be convenient, the dust filter 300 should be put in place when it is installed in its working position in the dust compartment 100. To solve this problem, the vacuum cleaner according to the present invention contains a locking mechanism 500 that does not not only allows easy removal of the dust filter 300, but also securely locks the dust filter 300 in its working position in the dust compartment 100.

As best seen from figures 6 and 7, the locking mechanism 500 includes guide grooves 510 made along the opposite side walls of the dust chamber 100, half-cylindrical locking recesses 520, made at the peripheral ends of the guide grooves 510, and mating half-cylindrical clamps 530 made on them opposite sides of the handle 330. The latches 530 have a shape that allows you to mate with the recesses 520, passing through the grooves 510, when you insert the cartridge filter 300 into place in the housing 1. To install the cassettes of the filter 300, the handle 330 of the dust filter 300 is positioned vertically so that the half-cylindrical clips 530 of the handle 330 are inserted into the guide grooves 510 of the dust compartment 100 when the clips 530 are located along the grooves 510. When the cartridge filter 300 is fully inserted, the clips 530 reach the locking recesses 520 at the ends the grooves 510. The locking recesses 520 have a shape that allows the latches 530 to rotate 90 ° to their lateral position.

To fix the filter cartridge in place, the handle 330 is rotated about an axis so as to rotate the semi-cylindrical clips 530 by 90 ° so that at least a portion of the diametrical surfaces of the clips 530 are adjacent to at least a portion of the walls of the locking recesses. To remove the dust filter 300 from the dust collection compartment 100, the handle 330 returns to the vertical position, and thus the semi-cylindrical latches 530 rotate, eliminating the fit to the walls of the locking recesses 520, which allows the latches to be unlocked for movement along the grooves 510. Accordingly, the dust filter 300 can be removed from compartment 100.

Obviously, the locking mechanism can be implemented in various forms and designs. For the locking mechanism, any structure can be used that interfaces elements that can be moved relative to each other to provide a detachable configuration in the first position and a locked configuration in the second position.

Although this invention has been described with reference to a container-type cyclone vacuum cleaner, the cassette filter of the present invention is not limited to these conditions of use. The proposed cassette filter can be used in many cleaning devices, including vertical-type vacuum cleaners, washing vacuum cleaners, etc. This cassette filter can also serve as the only filter in the vacuum cleaner and is not necessarily limited to functioning as an additional filter located along the flow direction behind the cyclone dust collector, as described above.

When the motor 400 of the vacuum cleaner according to the present invention is activated, the negative pressure generated in the dust collecting compartment 100 causes a strong suction force in the suction channel 2 of the vacuum cleaner through the hose 8 and the extension tube 3. As a result, air containing debris is drawn in through the suction channel 2 into cyclone dust collector 10. First of all, the air containing garbage is drawn into the cyclone body 20 in a tangential direction through the first connecting tube 21 and the air supply duct 23, forming an air vortex a howling stream moving down the dust collector 30. The centrifugal force of the rotating air separates the debris from the air, and the separated garbage is collected in the dust collector 30.

When the air stream reaches the bottom of the dust collector 30, the air containing debris is discharged into the vacuum cleaner body 1 through the small openings 42 of the grill assembly 40, the air outflow opening 24 and the second connecting pipe 22. Moreover, part of the debris in the air moving up the dust collector 30 is reflected from the plate 43, which serves to prevent the reverse movement of debris. The garbage still remaining in the air moving upward, after passing through the plate 43, is entrained in air and, thus, is discharged through the small holes 42 of the grating unit 40. In this case, the garbage larger than the small holes 42 is filtered out and accordingly filtered garbage returns to the swirling air stream.

Meanwhile, any debris that is still entrained in the air even after passing through the small openings 42 is discharged through the air outflow channel 24, through the small openings 42 of the grating unit 40 and is filtered out in an additional filter in the vacuum cleaner body. For this purpose, a reusable dust-collecting filter 300 is installed in the dust-collecting compartment 100 of the vacuum cleaner body. The purified air thus obtained after filtration on the additional filter is discharged out of the vacuum cleaner through the engine compartment 200.

When filling the dust filter 300 with debris, it can be removed from the dust chamber 100 and cleaned of debris by washing, shaking or otherwise and returned to the dust chamber 100. The user can also monitor the amount of garbage collected in the dust filter 300 through the inspection window 323 .

As noted above, according to the present invention, the use of a reusable dust filter 300 of a cassette type eliminates the need for consumable filters, such as paper filters, to be discarded. As a result, the maintenance cost of the vacuum cleaner is much reduced. Moreover, since nothing is thrown away, the user of the proposed vacuum cleaner will not have a negative impact on the environment. Furthermore, since according to the present invention, the reusable dust filter 300 may be smaller than a paper filter or bag, the size of the dust collecting compartment 100 of the vacuum cleaner body 1 is reduced. As a result, the body of the vacuum cleaner can be more compact and lighter in weight, and therefore more convenient for using and handling the vacuum cleaner.

Although a preferred embodiment of the present invention has been described above, it will be apparent to those skilled in the art that the present invention is not limited to a preferred embodiment and various changes and modifications can be made within the scope of the present invention as defined by the appended claims.
