Description

DEVICE OF SEPARATION OF THE GARBAGE FOR VACUUM CLEANER}

The present invention relates to a suction type cleaning device, and more particularly, to a dirt separation device by centrifugal separation.

The present invention is an improvement on the waste separation and collection system in a vacuum cleaner described in patent application WO 03/047412. One embodiment of the application includes an air inlet tube tangentially connected to a dirt separation chamber that defines an almost cylindrical inner space. At the center of the separation chamber, at least one opening is arranged and a conduit is connected to the suction section. In particular, the conduit comprises a filtration section.

In addition, the separation chamber has a waste discharge pipe in the radial direction, the discharge pipe is connected to a sealed container for collecting the centrifuged dirt.

One of the characteristics of this invention is that the air intake pipe and the waste discharge pipe are installed at about the same height in the waste separation chamber, and the radial cross section of the separation chamber is considerably reduced to 1 to 4 times the smallest cross section of the pipe in which the dirt carried from the nozzle moves. Will.

This arrangement makes it possible to reduce the overall size of the separation device without degrading the dirt separation effect.

According to one embodiment, a second filtration device is included in the center of the separation chamber, the filtration device being accessible by a lid blocking the center part.

The object of the present invention is to improve the ergonomics, accessibility and installation of the filtration device so that such filtration devices can be cleaned and / or replaced in a very simple and hygienic manner.

This object is achieved by a main device and an auxiliary device for dirt separation for a vacuum cleaner comprising a motor-fan part according to the invention. The apparatus is mounted in a frame of a vacuum cleaner and includes a conduit located in a torus-shaped main separation chamber that separates dirt using inertia, the conduit having a plurality of openings, through which only the opening and the separation chamber are ventilated. And the conduit is also connected to the motor-pan section, and includes a collecting vessel constituting a dirt separation aid and having a fine filter disposed in the air communication path between the conduit and the motor-pan section. The invention is in particular characterized in that the two devices are structurally connected to each other by hook means forming a structural locking, which devices are detachable from the frame of the vacuum cleaner.

The subassembly consisting of the filtration and separation devices of the dirt is detachable from the vacuum cleaner, so that the subassembly needs to be removed from the frame of the vacuum cleaner and cleaned, and in some cases, the filter assembly of the vacuum cleaner is replaced. This is much easier.

Preferably, the hook means can be released to allow the collection vessel to be detached from the conduit. By separation through this release, the cleaning of the various elements becomes easier.

Preferably, the conduit can easily hold the dirt separation device, including recesses so that the top is blocked and the user can hold the devices without touching the dust zone.

According to a preferred embodiment of the present invention, the central conduit has an edge ring at its bottom that is substantially perpendicular to the conduit, which forms one side of the separation chamber and the opposite side is the hook of the collecting vessel with the filter. Have means.

This configuration saves space and ensures significant mechanical durability between the collector and the conduit.

In addition, by allowing the filter to be attached to and detached from the collecting container, it is possible to make practical cleaning of the dirt separation aid used also for the dirt collection purpose.

Preferably, the conduit has walls that are inclined toward the separation chamber along the direction of air movement (F), and at each end of the conduit an opening is formed which is nearly flat and substantially parallel to the conduit below. The opening is located just below the opening of the wall.

The presence of inclined walls at the open position of the conduit can cause the particles to move away from the air intake conduit. On the other hand, there are openings at these wall ends to facilitate air communication in the conduit to minimize power loss. This method thus has the effect of allowing air to easily enter the conduit with the effect of the particle leaping by the walls.

In fact, each opening acts as a small separator in itself in that it can separate the path of the particles from the air. Multiple openings can reduce the speed of air at each opening position, which can limit power loss without reducing the centrifugation effect. The centrifugal effect is on the one hand also related to the air velocity and on the other hand to the radius of curvature of the air path. As here, by significantly reducing the radius of curvature, superior centrifugation performance can be achieved while limiting power loss.

Preferably, the wall abuts the side walls at both corners, which side walls are attached to the conduit. The presence of such sidewalls prevents particles from entering the opening of the conduit through the side of the inclined wall by a kind of airflow leak. Thus, the particle separation function is improved.

In addition, the shape of the inclined wall is formed so as not to overlap each other so as to form a blind spot where dust is accumulated. In this way, the presence of the sidewalls preserves the weak airflow circulating from each side of the walls without penetrating directly into the openings.

In order to improve the cover function at the height of the conduit in the air passing direction and in the vertical direction, the holes are preferably arranged in a 5-point shape.

According to another embodiment, the openings in the conduit position are formed elongate along the direction of rotation of the air, just below the inclined wall. This arrangement further limits the power loss by enlarging the surface through which the main air passes to slow down the air locally.

According to another embodiment, the openings may be elongated in a direction perpendicular to the flow rather than in the direction of air rotation, which increases the size of the opening through which air flows, preventing particles from breaking the path and increasing the chance of entering the opening. do.

The ability to separate the dirt separation main device from the auxiliary device is a very good advantage in implementations having these walls, whether or not the inclined walls of the conduit contain side walls. In fact, this separation allows the main device to be cleaned more cleanly than the auxiliary device, given the structural differences between these two devices. The main unit can be brushed especially with water and furthermore it can be turned into the dishwasher, which is almost impossible in a filter tank with a risk of breaking the filter.

In this embodiment, if the dirt separation device becomes more complicated due to the walls and even the side walls, the cleaning becomes more inconvenient. However, by separating it from the collecting container including the filter, the cleaning operation is much easier and the dust separation effect can be improved.

The invention also targets an electric vacuum cleaner comprising a frame 11 having a motor-fan part mounted therein. The frame includes an air inlet connected to the floor to be cleaned through a conduit with a nozzle at the end, the air inlet of the frame is connected to the tangential separation chamber 33 in the tangential direction. This vacuum cleaner is characterized in that it comprises dirt separation devices as described above.

Preferably, the separation chamber has a top closed off with a lid, the lid covering the top of the conduit through which externally accessible and purged air is discharged, and contacting with residual dust, most of which accumulates at the bottom of the separation device by gravity. To allow for easy access to the disconnect device while avoiding as much as possible.

In one of the possible embodiments of the invention in a vacuum cleaner, the separation chamber is connected to a detachable waste collection closure container, which is distinguished from the separation chamber via a discharge tube facing in a radial or tangential direction. With such a configuration, the sealed container can be taken out from the main device for separating wastes even if all the separation devices are not taken out.

Preferably, the waste separation devices are independent of the discharge pipe and the detachable waste collection container.

Thus, unlike many other cleaners, this arrangement saves the hassle of removing the waste collection container to clean the separation device and limits the risk of leaking or re-introduced dust from the parts to be cleaned. .

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 shows a vacuum cleaner equipped with separation devices according to the invention.

This vacuum cleaner 10 comprises a frame 11 which is supported on several wheels, in particular here two rear wheels 12. An airflow connection 14 connects the frame of the cleaner to the nozzle in contact with the floor to be cleaned so that the dirt flows into the frame of the cleaner. The cleaner generates an airflow to mount a motor-fan section (not shown) to collect dirt on the floor to be cleaned. The button 16 can start or stop the motor.

According to one aspect of the invention, the vacuum cleaner comprises a separation chamber by inertia. This compartment is accessible via a protective lid 18, which can also close the compartment. The waste separated by the device is discharged to the sealed container 22 for waste collection through the discharge pipe 39. The waste container for waste collection has a handle 20 so that the user can easily access and hold it by hand. The handle also serves as a handle for transporting the cleaner, where the cleaner is tilted as a whole and the handle is in a high position so that it can be easily held by hand while keeping the cleaner in its center of gravity.

According to the present embodiment, the container 22 can be emptied through any one of both sides, and both sides of the hermetically sealed container can be blocked by respective removable lids 21. This configuration allows the user to empty the container easily, either right handed or left handed.

As shown in detail in FIG. 2, the entire waste separation apparatus 30 has an air suction pipe 32 connected to a toric-shaped separation chamber 33 having a rectangular cross section in the radial direction. Preferably, the air intake pipe 32 includes an L-shaped joint 132 to reduce the possibility of dirt directly impacting the central conduit defining the torus.

The area through which air flow passes in the separation chamber is defined by a circular outer wall 34, a circular inner wall 35, a top wall 18 which forms a lid, and a bottom wall 37.

The circular inner wall defines an air exhaust conduit 36 and is connected between the separation chamber and the air exhaust conduit 36 through a plurality of openings 40 for the passage of air. The conduit 36 is closed in its upper part and is connected in air to a collecting vessel 38 having a filter, preferably a pleated filter. This collector is also connected to the motor-fan section for air communication. Through this configuration, it is possible to have a larger space in the size of the filter.

This embodiment of the present invention also has the significant advantage that the separation chamber has a lower height than the dirt suction conduit 32. The separation chamber cross section is formed at 1 to 4 times the minimum cross section of the tubes through which dirt sucked from the nozzle arrives, as described in patent application WO 03/047412. Of course, a sealing means is provided in the separation chamber position so that air does not leak.

In the following, the conduit 36 having an opening is referred to as the main separating device, and the collecting vessel 38 and its filter are referred to as the auxiliary separating device.

As shown in FIG. 3, the conduit 36 is structurally connected to a collecting vessel 38 with a fine filter in accordance with the present invention. In addition, the upper portion of the conduit 36 includes a symmetrical arc-shaped handle recess 42 so that the user can remove the separation device without touching the walls or the bottom wall 37 of the conduit, which is an area in contact with the dust. .

Thus, the separators can be taken out at the same time. In addition, only the lid 18 blocks the separation chamber. Therefore, only the lid can be opened to access the separation device, and the separation device can be easily taken out.

In addition, the separators are simply mounted inside the vacuum cleaner, so no tools are needed to remove the separator from the cleaner.

Preferably, as shown in FIG. 4, the collecting vessel 38 can be separated from the conduit 36, and the structural connection between these two elements can be released.

According to the present embodiment, the conduit 36 and the bottom wall 37 are formed of a single part, which solves the sealing problem in particular in this position. As a result, the operation of locking the collecting cylinder 38 to the conduit 36 takes place on the bottom wall 37. The bottom wall comprises hooks 52, as can be seen in FIG. 7, which engage the openings 50 provided in the top wall of the collecting container 38. This interlocking pin-shaped assembly allows simple structural connection and can be easily operated by the user.

Other structural means, such as clamps or assemblies, may be used for the structural connection between the collection vessel 38 and the conduit 36.

In addition, the bottom wall 37 is not necessary for the structural connection between the conduit 36 and the collection vessel 38. In particular, a system may be envisioned by fastening the engaging pins of the conduit directly into the cylindrical collector. In this case, the fixing system may be arranged on the walls of the collecting container 38.

According to this shape, a joint is provided between the conduit and the collecting container, and is formed by an elastomer mold around the bottom wall 37 and beside the hooks 52. Alternatively and / or supplementally, the joint may be provided around the upper flange of the collecting container 38.

In this embodiment, the collecting cylinder is in the form of a parallelepiped, in which a highly filterable pleated filter 46 for trapping fine dust is accommodated.

Preferably, a sponge 44 is provided between the filter 46 and the conduit 36 to effect preliminary filtration. The sponge is detachable from the collecting container 38.

In this embodiment, a grid 48 is positioned between filter 46 and sponge 44 to hold the filter in place. This grid also protects the filter against erroneous operation when cleaning the filter. At this time, the grid is bonded to the inner wall of the collecting container 38. The filter is also adhered to the collecting container 38 to ensure the sealing of this filtration operation. At this time, only one bonding operation is performed, but before the adhesive dries, a filter is attached and a grate is attached immediately after that. Thereby, the interdependent unit which consists of the collection container 38, the filter 46, and the grate 48 can be formed.

In a simplified form, the grate is omitted and only the filter can be glued to the collecting vessel 38.

For example, as shown in FIG. 5, the filter may be detachable through the grid clamp system, thereby facilitating filter replacement as well as cleaning of the filter.

6 to 10 show an improved variant of the dirt separation main apparatus. In this variant, the conduit 56 comprises an edge flange 57 which also forms part of the separation chamber and a recess 62 which forms the handle of the separation device. However, compared to the embodiment described above, the conduit has separators 70, which will be described in detail below, and are shown separately in FIG. 10. Walls 66 are located in front of each opening 64 formed in conduit 56 along the direction of rotation F of air in the separation chamber. These inclined walls have an opening 68 at the free end, which is nearly equilibrium with the conduit located below and is connected to the opening 64 through the free edge 69 in the front.

Preferably, the walls 66 include sidewalls 67 attached to the conduit 56 to prevent particles from entering the opening 64 by bypassing the inclined wall 66. Thus, these side walls form the longitudinal edge of the inclined wall.

Through this configuration, the path of the fine particles follows the inclined wall 66 and thus away from the conduit 56. Some of the particles are bounced off by the springs formed by the inclined walls 66.

However, through the openings 68 formed in the wall, air meets the conduit without having to change its path significantly. As shown by the path of air G in FIG. 9, the opening 68 facilitates the escape of air through the opening of the conduit without significantly degrading the particle separation effect.

In this embodiment, increasing the opening size of the conduit location minimizes power loss. That is, as can be seen in FIG. 10, the openings 64 extend downstream of the wall 56 along the general direction of movement of the airflow in the separation chamber. This configuration allows air to reach these openings 64 with less bending of the path, which means that power loss is reduced.

By thus protecting the openings 64 and increasing the number of inclined walls, particles are pushed over the walls and bounced away from the opening 64.

In operation, the user stops the motor-fan after cleaning the floor. Then, by pressing the button 24, the main container 22 for waste collection can be removed and emptied.

When cleaning the filtering devices, the lid 18 is opened and the devices are held through the recesses 42 and 62. The user may first shake the assembly on the bin containing the rubbish, and then separate the two devices by slightly turning the conduit against the collecting bin. This separated conduit can be washed in water, or more aggressively cleaned with a brush. These conduits are usually formed of plastics and can withstand the mechanical external forces of cleaning brushes and detergents. This aspect of cleaning is more important in that the conduit has the separators 70 described above, because these separators require more detailed cleaning while complicating the structure of the device. By being able to separate the conduit from the collecting filter 38 equipped with a fine filter, the user can use a more active and more effective cleaning method, so that the cleaning operation no longer has to be boring for a long time.

The segregation aid and its pleated filter can be shaken off and washed with water if the pleated filter is of a type that can be cleaned with water. The sponge 44 may be separated from the collecting container 38 and may also be simply washed with water.

In this embodiment, since the filter is adhered to the collecting container, the collecting container 38 must be replaced to replace the filter.

The reassembly of the various elements is simple and requires no tools, so the user can often perform this task, which prevents the malfunction of the devices and consequently the malfunction of the cleaner.

Separation device according to the present invention configured as described above has the advantage of much easier to clean and replace without reducing the size of the cleaner and the separation efficiency.
