Definitions
- the present invention relates to a detachable dust receptacle for use in a vacuum cleaner, the dust container being sealed to the vacuum cleaner body by means of lip seals, and to a vacuum cleaner which incorporates such a dust receptacle.
- Bagless vacuum cleaners often use cyclonic separation to separate dirt and dust debris from an airflow. Bagless vacuum cleaners maintain a consistently high level of suction, even as the dust collecting container incorporated into the vacuum cleaner fills with dirt.
- a bagless vacuum cleaner is a vacuum cleaner, which instead of utilizing a flexible bag, which may be disposable, for dust collection, uses a reusable container, which may be generally rigid, as compared with a bag.
- the inlet port of the detachable receptacle which receives dust-laden air from the hose, seals tightly against the hose joint in the vacuum cleaner body, in order not to get leakage of dust debris into the housing of the vacuum cleaner. Further, a tight sealing between the dust receptacle and the source of vacuum is important, otherwise could result in a reduced suction effect of the vacuum cleaner.
- the sealing element Upon removal from or insertion of the dust receptacle into the vacuum cleaner body, the sealing element is subject to great shear stress forces, which results in reduced useful life of the sealing element.
- a detachable dust receptacle for collecting dust in a vacuum cleaner, comprising an inlet port connectable to a hose joint in the vacuum cleaner for receiving dust-laden air, a suction port, to which a source of vacuum is connectable, a first sealing element arranged for establishing an effective sealing of the inlet port against the hose joint, and a second sealing element arranged for establishing an effective sealing of the suction port against the source of vacuum, wherein at least one of the sealing elements is a lip seal.
- an “effective sealing” is meant a sealing which maintains the negative pressure in the dust receptacle.
- An effective sealing is both essentially air tight and essentially dust tight.
- the invention is particularly useful in a bagless vacuum cleaner.
- the lip seal is sealingly engageable with the opposite surface. Unlike 0-rings, whose sealing effect is highly dependent on an axial compression pressure between the receptacle and the cover, the flexibly compressible lip of the lip seal has a self- sealing function.
- the lip seal between the receptacle and the cover is drawn radially inwards towards the opening between the cover and the receptacle by the vacuum formed in the vacuum cleaner.
- a part of the seal exerts a sealing axial force against the opposite surface. This results in a sealing effect which increases the larger the difference in pressure between the inside and the outside of the receptacle becomes.
- the lip seal Due to the flexibility and extent of the lip seal, it is not necessary with as close tolerances against the opposite surface as with other kinds of seals, for example O-rings.
- the lip seal gives an effective sealing between the receptacle and the vacuum cleaner body even though there is a small play between the two parts, the play being necessary for an easy detachment/attachment of the two parts. Thereby, the lip seal manages shear stress better than other kinds of sealing.
- the first sealing element is a lip seal.
- the lip seal may be attached at the inlet port of the receptacle. It may alternatively be attached at the hose j oint in the vacuum cleaner.
- the second sealing element is a lip seal.
- the lip seal may be attached at the suction port of the receptacle. It may equally well be attached at the source of vacuum in the vacuum cleaner.
- Both the first and the second sealing element may be lip seals.
- the inlet port and the suction port of the receptacle may be located at substantially opposite sides of the receptacle.
- the flow area cross-section of the inlet port and/or the suction port may be in a plane which is inclined between about 60 and about 0 degrees with respect to a direction in which the receptacle is arranged to be extractable from the vacuum cleaner.
- This plane may be inclined outwardly. It could also be inclined inwardly.
- Planes associated with both the inlet port and the suction port may be inclined. In one embodiment, both, planes may be outwardly inclined. In yet an alternative embodiment, one of the inlet port and the suction port is inwardly inclined and the other one is outwardly inclined, the outwardly inclined port being more inclined than the inwardly inclined port.
- Inclined planes facilitate the extraction of the receptacle from the vacuum cleaner body.
- the lip seal may be attached by using glue, by pressing/squeezing the base of the lip seal into a slit or by snapping it into place using protuberances, ridges or grooves arranged on the lip base.
- the base member of the lip seal is provided with at least one longitudinal ridge, which may facilitate the attachment of the lip seal in a slit in the receptacle or in the cover and keep the lip seal in place.
- the lip seal may be made of resiliently compressible material, such as rubber or rubber-like material.
- the lip of the lip seal is a sealing flange extending from a base member of the lip seal.
- the flange may have a substantially convex part which is arranged to sealingly engage against an opposite surface.
- the dust receptacle may be arranged to be attached to/detached from said vacuum cleaner in a direction which is essentially perpendicular to an imaginary line between the inlet port and the suction port.
- Fig. 1 shows a detachable dust receptacle being attached to a bagless vacuum cleaner.
- Fig. 2 shows a cross section of an embodiment of the lip seal.
- Fig. 4 is a schematic diagram illustrating angles of the inlet port (to the left) and the suction port (to the right).
- a detachable dust receptacle 1 for use in a vacuum cleaner 2 has a suction port 3 to which a source of vacuum 4 is applied when the dust receptacle 1 is located within the vacuum cleaner 2, and a vacuum is drawn through the suction port 3 and the inlet port 5, Fig. 1.
- the inlet port 5 is connected to a hose joint 6 for receiving dust-laden air.
- a first sealing element, a lip seal 7a, is arranged for establishing an effective sealing of the inlet port 5 against said hose joint 6.
- a second sealing element, which also may be a lip seal 7b is also arranged between the suction port 3 and the source of vacuum 4 for establishing an effective sealing.
- a flow area cross-section of the inlet port 5 and/or the suction port 3 is in a plane Pl, P2, respectively, which may be inclined at an angle al, a2, respectively, with respect to a direction D in which the receptacle 1 is arranged to be extractable from the vacuum cleaner 2, Fig. 1. These inclinations may be between 60 and 0 degrees.
- outwardly here means that a normal direction of the plane, at the outside of the container, points obliquely downwardly when the container is held in a substantially horizontal position.
- one of the planes Pl, P2 may be outwardly inclined, while the other one is substantially straight.
- both planes Pl, P2 are outwardly inclined.
- one of the planes Pl, P2 may be inwardly inclined, while the other plane is outwardly inclined.
- the outwardly inclined plane may have a greater angle of inclination than the inwardly inclined plane.
- the lip seal 7 consists of a base member 9 and a flexible and compressible lip member 10 extending from the base member 9, where the lip member 10 is sealingly engageable with the opposite surface.
- the base 9 of the lip seal 7 is of generally square or rectangular shape.
- the base member 7 may be substantially symmetric.
- One, two, three or more longitudinal ridges 11 or grooves on the base member 9 may be provided to facilitate the attachment of the lip seal 7 in a slit 12 in the receptacle 1 or in the vacuum cleaner body 2, and keep the lip seal 7 in place in the slit.
- the ridges 9 may interact with one or more grooves 12a, 12b to provide a positive interlocking effect, thus keeping the lip seal 4 securely in place.
- the lip seal 7b, 7b' may also be fastened to the receptacle 1 or to the vacuum cleaner body 2 by using glue.
- the slit 12 may, as illustrated, be formed by two separately formed parts, which when joined together provides a press fit for the base 9 of the lip seal 7.
- the lip member 10 may be a sealing flange, which may have a convex part arranged to sealingly abut against the opposite surface, upon being subjected to an underpressure.
- the sealing flange may be substantially arc-shaped but may equally well be straight.
- the flange could be of constant or varying thickness. It may extend from the side of the base member 9 or from the top of the same. It may be longer than the width of the base member 9 but it may also be shorter. The flange may extend beyond the side of the base member 9 opposing the attachment side.
- the base 9 and the lip 10 of the lip seal 7 do not have to be made of the same material and could exhibit different qualities. It is recognized that the lip seal 7 may be designed to allow smaller or larger tolerances, e.g. by varying the axial and/or radial length, the thickness, cross section geometry and the material of the lip 10.
- the lip member 10 may be designed, in its non-compressed state, to have an extent in the axial direction, which is larger than a largest permitted distance D between the receptacle 1 and the vacuum cleaner body 2. In various embodiments, the lip member 10 may extend 5%, 10%, 15%, 20%, 25%, 30%, 50%, 75%, 100%, 150%, 200% or 300% beyond that distance. Alternatively, or as a complement, a length r of the lip member 10, along a face that is to engage the opposing part, may be 5%, 10%, 15%, 20%, 25%, 30%, 50%, 75%, 100%, 150%, 200%, 300%, 400% or 500% longer than said distance.
