Description

Vacuum Cleaner Nozzle and Vacuum Cleaner

TECHNICAL FIELD

The present invention relates to a vacuum cleaner nozzle. The present invention further relates to a vacuum cleaner comprising a vacuum cleaner nozzle.

BACKGROUND

A vacuum cleaner comprises a vacuum cleaner nozzle which is moved along/over a surface to be vacuum cleaned. Dust and debris is sucked through a nozzle opening of the vacuum cleaner nozzle through the vacuum cleaner nozzle to an outlet of the vacuum cleaner nozzle and to the vacuum cleaner.

Vacuum cleaners are used on different kinds of surfaces, such as e.g. hard floor surfaces and carpeted surfaces. Some vacuum cleaner nozzles may be adapted for use on such different surfaces. The vacuum cleaner nozzle may for instance comprise bristles, which may be positioned to extend outside the vacuum cleaner nozzle for contacting a hard floor surface, and which may be positioned inside the vacuum cleaner nozzle for a base member of the vacuum cleaner nozzle to contact a carpeted surface. When the bristles contact a hard surface, they may prevent the vacuum cleaner nozzle from scratching the hard surface. Also, on a hard surface the bristles ensure that an airgap is provided between the base member and the hard surface to permit an airflow into the vacuum cleaner nozzle. If there is no airgap, there is no airflow and accordingly, no pick-up of dust and debris. When cleaning a carpeted surface, the bristles are not required and thus, are retracted to within the vacuum cleaner nozzle. Instead the base member directly contacts the carpeted surface and the airflow into the vacuum cleaner nozzle flows through the carpeted surface, which ensures a good dust and debris pick-up capability of the vacuum cleaner nozzle on the carpeted surface.

Modern vacuum cleaners are subjected to increasing legislative energy consumption restrictions. Accordingly, lower power ratings of vacuum cleaners entail that power available for producing an airflow through a vacuum cleaner nozzle is reduced compared to older vacuum cleaners. Thus, improved efficiency of vacuum cleaners is required to maintain adequate dust and debris pick-up capability in vacuum cleaners. SUMMARY

It is an object of the present invention to provide a vacuum cleaner nozzle with improved efficiency when a brush carrying member of the vacuum cleaner nozzle contacts a surface to be cleaned.

According to an aspect of the invention, the object is achieved by a vacuum cleaner nozzle comprising a housing having a base member, a suction conduit extending through the housing for conducting an airflow from the base member towards an outlet of the vacuum cleaner nozzle, and a brush carrying member. The suction conduit comprises an elongated nozzle opening provided in the base member. The brush carrying member is movable in relation to the base member between a first position and a second positon, in which first position a portion of the brush carrying member extends outside the housing beyond the base member and the elongated nozzle opening for contacting a surface to be vacuum cleaned, and in which second position the brush carrying member is retracted within the housing such that at least a portion of the base member is arranged for contacting a surface to be vacuum cleaned. The vacuum cleaner nozzle comprises a sealing, the sealing providing a seal between at least part of the base member and the brush carrying member when the brush carrying member is in the first position. Since the vacuum cleaner nozzle comprises a sealing, the sealing providing a seal between at least part of the base member and the brush carrying member when the brush carrying member is in the first position, an airflow is prevented from flowing between at least part of the base member and the brush carrying member to the elongated nozzle opening. Thus, when a portion of the brush carrying member contacts a surface to be cleaned, an increased airflow along the surface to be cleaned is achieved. As a result, the above mentioned object is achieved.

The vacuum cleaner nozzle is configured to be moved along a surface to be cleaned, such as a floor. The vacuum cleaner nozzle may be configured to be connected to a vacuum cleaner. The brush carrying member may comprise bristles arranged to abut against the surface to be cleaned in the first position of the brush carrying member. The elongated nozzle opening may extend across a major portion of the vacuum cleaner nozzle. The vacuum cleaner nozzle may be configured to be moved back and forth with long sides of the elongated nozzle opening being directed substantially perpendicularly to the back and forth movement. The base member is arranged at a side of the housing configured to face the surface to be vacuum cleaned, such as e.g. at lower side of the housing. The elongated nozzle opening may be configured for admitting dust and debris into the suction conduit. An airflow produced by a suction producing unit of a vacuum cleaner may flow through the elongated nozzle opening and via the suction conduit to the outlet of the vacuum cleaner nozzle. The dust and debris may be transported by the airflow. According to a further aspect of the present invention there is provided a vacuum cleaner comprising a vacuum cleaner nozzle according to any one aspect and/or embodiment discussed herein.

The vacuum cleaner may be e.g. of the canister type, the stick type, or the upright type.

Further features of, and advantages with, the present invention will become apparent when studying the appended claims and the following detailed description.

DETAILED DESCRIPTION

Aspects of the present invention will now be described more fully. Like numbers refer to like elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and/or clarity.

Fig. 1 illustrates a top view of vacuum cleaner nozzle 2 according to embodiments. The vacuum cleaner nozzle 2 is configured to be moved along a surface to be cleaned, such as a floor. The vacuum cleaner nozzle 2 comprises a housing 4, a suction conduit 6 extending through the housing 4 for conducting an airflow from a base member of the housing 4 towards an outlet 8 of the vacuum cleaner nozzle 2. The base member faces the surface to be cleaned during use of the vacuum cleaner nozzle 2. During use, a vacuum cleaner is connected to the outlet 8 of the vacuum cleaner nozzle 2 and a conduit connects the outlet 8 with a suction producing unit of the vacuum cleaner. The suction conduit 6 comprises an elongated nozzle opening 9 provided in the base member. The elongated nozzle opening 9 is illustrated with a broken line. The elongated nozzle opening 9 extends across substantially the entire vacuum cleaner nozzle 2. During use of the vacuum cleaner nozzle 2, the elongated nozzle opening 9 may extend across a direction of movement 7 of the vacuum cleaner nozzle 2 in order to provide a broad coverage of the surface to be cleaned.

Figs. 2A and 2B illustrate cross sections through the vacuum cleaner nozzle 2 of Fig. 1. Fig. 2A illustrates a cross section along line A - A in Fig. 1 , and Fig. 2B illustrates a cross section along line B - B in Fig. 1. As mentioned above, the vacuum cleaner nozzle 2 comprises a housing 4 comprising a base member 10. The housing 4 further comprises a top cover 1 1 , which defines at least part of an upper delimitation of the vacuum cleaner nozzle 2. Accordingly, during use of the vacuum cleaner nozzle 2, the top cover 1 1 faces upwardly and the base member 10 faces downwardly. Each of the top cover 1 1 and the base member 10 may comprise one or more separate parts, which are fixedly connected to each other. The top cover 1 1 and the base member 10 are fixed in relation to each other, either directly to each other or indirectly, it would e.g. be possible to have the base member fixed to an internal part and/or structure of the housing 4. Accordingly, the base member 10 forms a fixed portion of the housing 4.

The suction conduit 6 extends through the housing 4 from the elongated nozzle opening 9 in the base member 10 towards the outlet of the vacuum cleaner nozzle 2. The outlet 8 of the vacuum cleaner nozzle 2 may be arranged at a distance from the housing 4 as illustrated in Fig. 1 alternatively, the outlet may be arranged in or at the housing 4, e.g. at the cross sectional position C of the suction conduit 6 indicated in Fig. 2A. The vacuum cleaner nozzle 2 further comprises a brush carrying member 12. The brush carrying member 12 is movably arranged within the housing 4. The brush carrying member 12 extends around at least a portion of the base member 10 inside the housing 4. The brush carrying member 12 is movable in relation to the base member 10 between a first position and a second positon. The vacuum cleaner nozzle 2 comprises a sealing 14 for providing a temporary airtight seal between at least part of the brush carrying member 12 and the base member 10 when the brush carrying member 12 is in its first position, as will be discussed further below.

In Figs. 2A and 2B the brush carrying member 12 is illustrated in the first position. Figs. 3A and 3B illustrate cross sections through the vacuum cleaner nozzle 2 of Fig. 1 . Fig. 3A illustrates a cross section along line A - A in Fig. 1 , and Fig. 3B illustrates a cross section along line B - B in Fig. 1 . In Figs. 3A and 3B the brush carrying member 12 is illustrated in the second position. In the following description related to the first and second positions reference will be made to Figs. 2A - 3B.

In the first position of the brush carrying member 12, a portion of the brush carrying member 12 extends outside the housing 4 beyond the base member 10 and the elongated nozzle opening 9 for contacting a surface to be vacuum cleaned during use of the vacuum cleaner nozzle 2. Put differently, in the first position at least a portion of the brush carrying member extend beyond a floor facing surface of the base member 10. Thus, for instance bristles 16 of the brush carrying member 12 may contact the surface to be vacuum cleaned when the brush carrying member 12 is in its first position. The portion of the brush carrying member 12 extending outside the housing 4, beyond the base member 10 and the elongated nozzle opening 9, may be a portion of the bristles 16. In the second position of the brush carrying member 12, the brush carrying member 12 is retracted within the housing 4 such that a least a portion of the base member 10 is arranged for contacting a surface to be vacuum cleaned. Put differently, in the second position the brush carrying member 12 is retracted within the housing 4 such that the elongated nozzle opening 9 is closer to the surface to be cleaned than the brush carrying member 12, during use of the vacuum cleaner nozzle 2. When the brush carrying member 12 is in its second position, it may be positioned in its entirety within the limits of the housing 4.

According to some embodiments the brush carrying member 12 may comprise bristles 16 and a bristle holder 18. The bristles 16 may be fixedly attached to the bristle holder 18. In this manner bristles 16 may be provided for cleaning hard surface. When the brush carrying member 12 is arranged in its first position, at least part of the bristles 16 may extend beyond the base member 10 to contact a surface to be vacuum cleaned when the vacuum cleaner nozzle 2 is moved along the surface to be vacuum cleaned. In the second position of the brush carrying member 12 the bristles 16 may be retracted into the housing 4 to such an extent that the base member 10 may contact a surface to be cleaned. With the brush carrying member 12 in its first position, when the bristles 16 contact a hard surface to be cleaned, the base member 10 is substantially prevented from contacting the surface to be cleaned. Accordingly, there is less risk for the hard surface to be scratched as the vacuum cleaner nozzle 2 is moved along the hard surface. The base member 10 provides a relatively even surface facing a surface to be cleaned, compared to when the bristles 16 contact the surface. Thus, with the brush carrying member 12 in its second position, when the base member 10 contacts a surface to be cleaned, a tight contact is provided between the base member 10 and the surface to be cleaned. This ensures a high air velocity as surrounding air is sucked between the surface to be cleaned and the base member 10 into the elongated nozzle opening 9 during vacuum cleaning. The vacuum cleaner nozzle 2 with the brush carrying member in its second position may suitably be used for cleaning soft surfaces such as carpeted surfaces, which do not risk being scratched.

As mentioned above, the vacuum cleaner nozzle 2 comprises a sealing 14. The sealing 14 provides a seal between at least part of the base member 10 and the brush carrying member 12 when the brush carrying member 12 is in the first position, as illustrated in Figs. 2A and 2B. The seal prevents air from passing between at least part of the base member 10 and the brush carrying member 12. Thus, an airflow from within the housing 4, not passing between a surface to be cleaned and the portion of the brush carrying member 12 extending outside the housing 4 beyond the base member 10, such as e.g. the bristles 16, is prevented at least to some extent. An efficient dust and debris pick-up may thus be provided with the brush carrying member 12 in its first position. Accordingly, the sealing 14 may extend between at least part of the base member 10 and the brush carrying member 12 when the brush carrying member 12 is in the first position to provide an airtight seal between at least part of the base member 10 and the brush carrying member 12. That is, the airtight seal may extend along an extension of the sealing 14.

According to embodiments, the sealing 14 may be attached to one of the brush carrying member 12 and the base member 10. The sealing 14 may abut against the other of the brush carrying member 12 and the base member 10 when the brush carrying member 12 is in the first position. In his manner the sealing 14 may provide the seal between the brush carrying member 12 and the base member 10. In the embodiments illustrated in Figs. 2A - 3B the sealing 14 is attached to the brush carrying member 12.

According to some embodiments, the sealing 14 may comprise a resilient material. In his manner a tight seal may easily be provided between the brush carrying member 12 and at least part of the base member 10 when the brush carrying member 12 is in its first position. The resilient material may comprise e.g. a thermoplastic elastomer, a rubber material, or similar material. According to some embodiments, the sealing 14 may comprise a lip seal. That is, the sealing 14 may comprise a member, which is thin and narrow and is bendable. Thus, when the sealing 14 abuts against the brush carrying member 12 or against the base member 10, the lip seal may bend at least to same degree in order to provide an abutment force between the sealing 14 and the brush carrying member 12 or the base member 10. Thus, a substantially airtight seal may be provided between the brush carrying member 12 and the base member 10 along the extension of the sealing 14.

According to embodiments, the brush carrying member 12 may be releasably lockable in the first position. In his manner it may be ensured that the brush carrying member 12 remains in the first position until the brush carrying member 12 is released and may return to the second position. The brush carrying member 12 may be biased towards the second position.

The brush carrying member comprises a cam 13. A cam follower 15 is provided on a pivotable member 17. A user of the vacuum cleaner nozzle 2 may use his/her foot to pivot the pivotable member 17 between its position shown in Fig. 2B and its position shown in Fig. 3B. When the brush carrying member 12 is in the second position, Fig. 3B, the cam follower 15 may rest against the cam 13. As a user presses the pivotable member 17, the cam follower 15 will track along the cam 13 and thus, force the brush carrying member 12 into its first position, Fig. 2B. In order to lock the brush carrying member 12 in the first position, the cam follower 15 may engage with the cam 13 when the brush carrying member 12 is in the first position. The user may have to manipulate the pivotable member 17 to release the cam follower 15 from its engagement with the cam 13.

The sealing 14 may comprise a flexible lip, which seals against the base member 10, as shown in Figs. 2A and 2B. In the alternative embodiments, according to which the sealing 14 is attached to the base member 10, the flexible lip may instead seal against the brush carrying member 12.

Namely, when vacuum cleaning a hard surface, it is desirable to achieve a large airflow along the hard surface to be cleaned. In airflow from above, from within the housing 4, directly into the elongated vacuum cleaner nozzle 9 and bypassing the bristles 16, does not contribute to efficient dust and debris pick-up.

A vacuum cleaner nozzle 2 according to the present invention comprising a sealing 14 and with a brush carrying member 12 in its first position is more efficient, then a vacuum cleaner nozzle wherein air may pass between the brush carrying member and the base member substantially around the entire nozzle opening when such a brush carrying member is in its corresponding first position. When the brush carrying member 12 is in the second position, as illustrated in Figs. 3A and 3B, the sealing 14 is not effective and air may pass from within the housing 4 between the brush carrying member 12 and the base member 10, as indicated by arrows 20 in Fig. 3A. Thus, an air passage 22 may be provided between the brush carrying member 12 and at least part of the base member 10 when the brush carrying member 12 is in the second position. In his manner a high airflow to the elongated nozzle opening 9 may be provided.

When the base member 10 contacts the surface to be cleaned, air flows through a narrow passage formed around the elongated nozzle opening 9, between the base member 10 and the surface to be cleaned. Alternatively, or additionally, air flows through the surface to be cleaned, e.g. in case of a carpeted surface. Due to this all surrounding air flowing into the elongated nozzle opening will pass close to the surface to be cleaned, and/or through the surface to be cleaned thus, producing a high airflow entraining dust and debris into the elongated nozzle opening 9. An as unrestricted airflow as possible towards the elongated nozzle opening 9 is desirable. Accordingly, an airflow not only from surroundings of the vacuum cleaner nozzle 2, but also from within the housing 4 may assist in maximising the airflow towards the elongated nozzle opening 9. Due to the base member 10 contacting the surface to be cleaned, the airflow passing into the elongated nozzle opening 9 will pass along the surface to be cleaned, and/or through the surface to be cleaned, irrespective of where the airflow comes from. The additional airflow through the air passage 22 provided between the brush carrying member 12 and at least part of the base member 10 when the brush carrying member 12 is in the second position may also contribute to reduce motion resistance of the vacuum cleaner nozzle 2 as it is moved along a surface to be cleaned. The airflow may contribute to reducing a vacuum which sucks the vacuum cleaner nozzle 2 towards the surface to be cleaned thus, reducing a force pushing the vacuum cleaner nozzle 2 towards e.g. a carpet, which will result in easier movement of the vacuum cleaner nozzle 2 along the carpet.

As is clearly shown in Figs. 3A and 3B, the bristle holder 18 may be arranged inside the housing 4, and wherein seen in the second position, the bristles 16 may extend towards the base member 10 along at least one side of the elongated nozzle opening 9.

Fig. 4 illustrates a partial exploded view of the vacuum cleaner nozzle 2 of Fig. 1. More specifically, the top cover of the housing has been omitted and only the base member 10, brush carrying member 12, and the sealing 14 are shown in Fig. 4. The base member 10 is shown with the elongated nozzle opening facing downwardly. The brush carrying member 12 comprises the bristle holder 18 and the bristles 16. The bristles 16 are arranged in bunches along a leading portion 26 of the brush carrying member 12. In Fig. 4 the bristles 16 are only schematically indicated. Along a trailing portion 27 of the brush carrying member 12, there may also be provided bristles and/or a resilient trailing edge (both alternatives indicated with the reference numeral 28). A member 24 integrated with, or forming part of, the base member 10 forms at least part of the suction conduit 6 extending through the vacuum cleaner nozzle 2. The bristle holder 16 is provided with an opening 30. The suction conduit 6 extends through the opening 30 in the bristle holder 18. That is, in an assembled vacuum cleaner nozzle 2, the suction conduit 6 extends through the bristle holder 16 and the brush carrying member 12 through the opening 30. In his manner the brush carrying member 12 may be conveniently arranged above the base member 12 with the bristles 16 arranged in front of the leading portion 36 of the base member 10., in order for the bristles 16 to extend beyond the base member 10 when the brush carrying member 12 is arranged in the first position.

According to embodiments, the sealing 14 may comprise a leading sealing portion 32 and a trailing sealing portion 34. The leading sealing portion 32 may provide a seal between a leading portion 36 of the base member 10 and the leading portion 26 of the brush carrying member 12, and the trailing sealing portion 34 may provide a seal between a trailing portion 38 of the base member 10 and the trailing portion 27 of the brush carrying member 12, when the brush carrying member 12 is in the first position. In his manner the sealing 14 may provide a seal between the brush carrying member 12 and the base member 10 substantially along both their respective leading and trailing portions 26, 27, 36, 38.

More specifically, the leading sealing portion 32 may be arranged on the bristle holder 18 inside of the bristles 16, and the trailing sealing portion 34 may be arranged on the bristle holder 18 inside of the bristles/edge 28, see also Figs. 2A - 3B.

The leading sealing portion 32 and the trailing sealing portion 34 may extend along substantially an entire width of the vacuum cleaner nozzle 2, and or along substantially an entire width of the elongated nozzle opening 9, see also Fig. 1 wherein the wits of the vacuum cleaner nozzle 2 and the elongated nozzle opening 9 extend perpendicularly to the direction of movement 7 of the vacuum cleaner nozzle 2.

Figs. 5a - 5c illustrate various embodiments of vacuum cleaners 50. Each of the vacuum cleaners 20 comprises a vacuum cleaner nozzle 2 according to any one aspect and/or embodiment discussed herein. The vacuum cleaner 50 in Fig. 5a is of the upright type, wherein the vacuum cleaner nozzle 2 is directly connected to a body 56 of the vacuum cleaner 50. The vacuum cleaner in

Fig. 5b is of the canister type, wherein a body 56 of the vacuum cleaner 50 is connected to the vacuum cleaner nozzle 2 via a tube/hose 58. The vacuum cleaner 50 in Fig. 5c is of the stick type, wherein a body 56 of the vacuum cleaner is integrated in a shaft 54, which in turn is connected to the vacuum cleaner nozzle 2.

It is to be understood that the foregoing is illustrative of various example embodiments and that the invention is defined only by the appended claims. A person skilled in the art will realize that the example embodiments may be modified, and that different features of the example embodiments may be combined to create embodiments other than those described herein, without departing from the scope of the present invention, as defined by the appended claims.
