Description

Technical field

The invention relates to a dust collector for a vacuum cleaner, comprising a dust bag made of a breathable material and a connecting plate surrounding the inlet in the dust bag, so that when the connecting plate is inserted into the holder of the vacuum cleaner, the connecting plate ensures the correct position of the inlet in vacuum cleaner. The invention also relates to aspects of the vacuum cleaner in relation to the holder for the dust collector.

Prior Art

An example of such a dust collector is disclosed, for example, in WO-02/24046-A1. Due to the connection plate, the inlet of the dust bag can be reliably positioned and oriented to receive dust-laden air from the inlet of the vacuum cleaner. In addition, the connection plate may include means for fixing the dust bag during use, as well as attaching elements of the connection plate, such as a shutter, to the vacuum cleaner when removing the dust bag, so as to automatically close the dust bag when it is removed.

US 2009/089966 discloses an apparatus for use with a vacuum cleaner bag filter comprising an annular inlet panel. The panel is inserted into the support structure at an installed position in which the tubular element of the vacuum cleaner enters the bag through the inlet. The support structure includes a protrusion that holds the panel in position. The support structure also includes a hinge that abuts against the edge of the panel to direct the movement of the panel in the installed position pivotally relative to the abutment edge.

From patent document EP 0 790 030 a detection device for a filter bag for a vacuum cleaner is known. The plate connector is fixed around the hole in the bag and is held in position against the wall of the vacuum cleaner by a protrusion extending through the hole in the connector.

DE 102005041811 discloses a vacuum cleaner dust bag with a plastic flange for connecting said vacuum cleaner bag to a corresponding vacuum cleaner inlet. In order to reduce manufacturing costs, the plastic flange includes a seal for sealing the connection between the plastic flange and the inlet, said seal being integral with the plastic flange.

Further, the connecting plate can actuate a feedback switch in the holder of the cleaner to ensure that the dust box is properly installed in the holder and prevent the cleaner from being used if the dust box is missing or improperly installed. When using the vacuum cleaner, if the dust box is missing or incorrectly installed, damage to the vacuum cleaner may occur due to the suction of dust-laden air into the fan or motor.

One of the problems associated with the use of dust collectors of this type is to improve the attachment of the dust bag to the vacuum cleaner during use, to remove the dust bag, and/or to provide a more universal way to detect the absence or improper installation of the dust bag.

Embodiments of the invention

The following is a detailed description of various embodiments of the invention with reference to the drawings. The invention, however, may be embodied in many different forms, and is not limited to the embodiments discussed in the description; these options are provided only as illustrative examples to make the disclosure of the invention more detailed and complete in order to more fully represent the scope of the invention for specialists in this field. The same elements in the description are indicated by the same reference signs.

In FIG. 1 shows a dust collector 20 for a vacuum cleaner according to the embodiments. The dust container 20 includes a dust bag 21 made of a breathable material and a connection plate 10. The connection plate 10 surrounds the inlet 9 of the dust bag 21. The connection plate 10 is configured to ensure the correct positioning of the inlet 9 in the vacuum cleaner by inserting the connection plate 10 into the holder of the vacuum cleaner. The connecting plate 10 has a front surface 5 in which an opening 6 is provided for the passage of an air flow. The opening 6 is located on the inlet 9 of the bag 21 for collecting dust. When using the dust collector 20 in a vacuum cleaner, through the opening 6 and the inlet 9, air containing dust and debris is sucked into the dust bag 21. Dust and debris accumulate inside the dust bag 21 while air is drawn through the breathable material to the air outlet of the vacuum cleaner.

The connection plate 10 also comprises a first side 1 inserted into the vacuum cleaner holder and a second side 2 located opposite it. The third side 3 connects the first and second sides, and the fourth side 4 connects the first and second sides. The first side 1 connects the third side 3 and the fourth side 4. The third and fourth sides 3, 4 are located opposite each other. The third and fourth sides 3, 4 can run parallel to each other.

When the first side 1 is inserted into the vacuum cleaner holder and the connection plate 10 is slid into the holder, the third and fourth sides 3, 4 enter into the holder. The second side 2 can enter the holder last. After that, the dust collector 20 is installed in the vacuum cleaner and is ready for use. Alternatively, when the ready-to-use dust container 20 is installed in the vacuum cleaner, the second side may not fit into the holder, i. e. may be outside the holder.

The connecting plate 10 contains two control holes 7, 8.

In the embodiments shown in FIG. 1 and 2, the third side 3 and the fourth side 4 are located at the same distance/radius R1, R2 from the center of the hole 6, and the two test holes 7, 8 are also at substantially the same distance/radius R1, R2 from the center of the hole 6 .

More specifically, the distance/radius R1, R2 from the center of the hole 6 at which the third and fourth sides 3, 4 are located is the minimum distance/radius from the center of the hole 6 to the third and fourth sides 3, 4, respectively. The two control holes 7, 8 are located at a distance/radius R1, R2 from the center of the hole 6 corresponding to this minimum distance/radius. Two control holes 7, 8 are displaced in a circle relative to the center of the hole 6, at the aforementioned minimum distance/radius from which the third and fourth sides 3, 4 are located.

Alternatively, the third side 3 may be located at a first distance/radius R1 from the center of the hole 6, and the fourth side 4 may be located at a second distance/radius R2 from the center of the hole 6. At least the first inspection hole 7 is located essentially on the first distance/radius R1 from the center of the hole 6, and/or at least the second control hole 8 is located essentially at the second distance R2 from the center of the hole 6.

More specifically, the first distance/radius R1 from the center of the hole 6 where the third side 3 is located is the minimum distance/radius from the center of the hole 6 to the third side 3. The second distance/radius R2 from the center of the hole 6 where the fourth side 4 is located , is the minimum distance/radius from the center of the hole 6 to the fourth side 4. The first inspection hole 7 can be located essentially at the first distance/radius R1, being circumferentially offset from the center of the hole 6 from where at a given minimum distance/radius a third side 3 is located from the center of the hole 6. The second inspection hole 8 can be located essentially at a second distance/radius R2, being circumferentially offset relative to the center of the hole 6 from the place where the fourth side is located at a given minimum distance/radius from the center of the hole 6. side 4.

In FIG. 1 and 2 show a connecting plate 10, both inspection holes 7, 8 of which are located in the area between the hole 6 and the first side 1. Alternatively, at least part of both inspection holes 7, 8 can be located in the area between the hole 6 and the first side 1.

In FIG. 1 and 2 show a connection plate 10 comprising a first inspection hole 7 located in the area between the hole 6 and the third side 3 and a second inspection hole 8 located in the area between the hole 6 and the fourth side 4.

In FIG. 1 shows embodiments in which both inspection holes 7, 8 are through holes made in the connecting plate 10. Thus, the fixing element of the vacuum cleaner can pass through at least one of the inspection holes 7, 8 when the dust collector 20 is installed in vacuum cleaner. Alternatively, the mechanical sensing element may enter one or both of the control holes 7, 8 when the dust collector 20 is installed in the vacuum cleaner. Another embodiment may be a variant with a sensing element containing a light sensor for emitting light through at least one of the control holes 7, 8.

The first side 1 is a rigid element connecting the third 3 and fourth 4 sides. More specifically, the part of the connecting plate 10 extending along the first side 1 may extend between the third side 3 and the fourth side 4. The part of the connecting plate 10 extending along the first side 1 may form one part of the connecting plate 10, or as shown in FIG. . 1, the part of the connecting plate 10 extending along the first side 1 can be separated from the central part of the connecting plate 10 by a groove.

The first side 1 may form the part of the connection plate 10 furthest from the opening 6. In other words, of the four sides 1, 2, 3, 4 available, the first side 1 may be located at the maximum distance from the center of the opening 6. More specifically, of all the shortest distances from the center of hole 6 to each of the first to fourth sides, the shortest distance to the first side 1 can be the longest.

As shown in the embodiments of FIG. 1 and 2, the surface of the second side 2 is located closer to the hole 6 than the surface of the first side 1.

The connecting plate 10 contains a flexible zone 13 located between the opening 6 and the first side 1, and this flexible zone 13 can be bent about an axis parallel to the surface of the first side 1.

Due to the presence of the flexible zone 13, part of the connecting plate 10 can bend and assume a curved shape. The flexible area 13 is designed so that when the flexible area 13 is bent, the area around the opening 6 can remain flat. This simplifies the connection to the inlet hose of the vacuum cleaner.

As a rule, the flexible zone 13 is designed in such a way that it can be easily folded back towards the dust bag, so that the connection plate 10 is best inserted into the vacuum cleaner. Flexibility can be provided, for example, with flexible hinges or perforations.

In FIG. 1 and 2 show the handle 11 located on the second side 2.

On the second side 2 there is also a protrusion 12 which extends laterally outward relative to the third 3 and/or fourth 4 side. In these embodiments, the second protrusion 12 is located on the second side 2 such that one of the protrusions protrudes laterally outward relative to the third side 3 and the second protrusion 12 protrudes laterally outward from the fourth side 4. Due to the fact that at least one the protrusion 12 protrudes laterally outward relative to the third and/or fourth side 3, 4, the protrusion 12 can abut against the vacuum cleaner holder, into the holder of which the connecting plate 10 is inserted. Thus, the protrusion 12 can position the connecting plate 10 in the vacuum cleaner holder.

The connection plate 10 may include a shutter 14. Typically, the shutter 14 is used to close the opening 6 and thus the inlet 9 when the dust container 20 is full and needs to be replaced. Since the shutter 14 substantially seals the opening 6, it prevents dust from the dust bag 21 from escaping to the outside when it is replaced.

As shown in FIG. 2, the shutter 14 can slide upwards away from the first side 1, moving over the inlet 9 of the dust bag and thus effectively closing the inlet.

The interconnecting plate 10 in question can be made of, for example, polypropylene or paper.

In FIG. 3 and 3a show a vacuum cleaner 22. The connecting plate 10 can be inserted into the holder 23 of the vacuum cleaner 22. The third side 3 and the fourth side 4 slide into the holder 23 of the vacuum cleaner. The first side 1 of the connecting plate first enters the holder 23.

The cleaner holder 23 may be fixed inside the cleaner, or may be removable. The holder 23 may include a fixing element 24, such as a hook or a pin 24, for fixing the dust collector during operation. The locking element 24 engages with at least one, preferably two inspection holes 7, 8. This can be done by inserting the locking element 24 into one or both of the inspection holes 7, 8. Preferably, the locking elements 24 engage with both control holes to ensure a secure fit.

When removing the dust collector, the locking element 24 disengages from the control holes 7, 8 when a certain force is applied, which is achieved, for example, by using spring-loaded locking elements or snap-type elements. The locking elements 24 can also be disengaged from the control holes 7, 8 automatically or manually.

Alternatively, the dust container holder 23 may include a sensing element such as a light sensor or a mechanical sensor.

The sensing element may be a mechanical sensor in the form of a hook or pin 24 engaging one or both of the control holes 7, 8 when the connection plate 10 is inserted into the holder 23. Such a sensor may then send information to the vacuum cleaner 22 that the required dust collector is installed. More specifically, the control system of the vacuum cleaner 22 can confirm that an appropriate dust container has been installed in the vacuum cleaner 22. In addition, or alternatively, the control system 22 can confirm that the connecting plate 10 is properly seated in the holder 23.

In yet another embodiment, the sensing element may be a light sensor comprising a light emitter mounted on one side of the connector plate 10 and a light receiver mounted on the other side of the connector plate 10. When the connector plate 10 is correctly installed in the holder 23, the light sensor emits into the vacuum cleaner a signal that the dust container is correctly installed in the holder. More specifically, when the connecting plate 10 is correctly installed in the holder 23, the light sensor can send information to the control system of the vacuum cleaner 22 that the dust bag is installed correctly. Light sensors can be located next to one, preferably both control holes 7, 8.

In FIG. 3b shows the connection plate 10 of the dust collector installed in the holder 23 of the vacuum cleaner 22 in perspective view. For the sake of clarity, the dust bag of the dust collector in FIG. 3b is not shown. The first side 1 of the connecting plate 10 is inserted into the holder 23 of the vacuum cleaner, and the third and fourth sides are inserted into the holder 23.

In embodiments in which the link plate includes one or two protrusions 12 projecting laterally outward from the third and/or fourth side, these one or two protrusions 12 can position the link plate 10 in the vacuum cleaner holder 23. These protrusions can rest against the corresponding parts of the holder 23.

The invention is not limited to the examples described above, and various changes, additions and modifications are possible within the scope of claims according to the claims.
