Definitions
- the present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a noise absorbing apparatus, which is disposed on an air path between a cleaner body and a brush assembly to absorb noises generated from the vacuum cleaner.
- a vacuum cleaner takes in air laden with dust and/or foreign substances from a surface to be cleaned by using a suction force generated from a suction motor, and separates the dust and/or the foreign substances from the air.
- the vacuum cleaner can be classified into an upright type vacuum cleaner, a canister type vacuum cleaner, a stick type vacuum cleaner, etc., according to a shape thereof.
- the canister type vacuum cleaner is provided with a cleaner body, a brush assembly, and air passage members.
- the cleaner body has a suction motor and a dust collecting unit therein.
- the brush assembly comes in contact with a surface to be cleaned and thus takes in dust and/or foreign substances from the surface to be cleaned.
- the air passage members are disposed between the cleaner body and the brush assembly to guide the air taken in through the brush assembly toward the cleaner body.
- the air passage members are usually made up of an extending tube, a handle member, and a flexible member. That is, the brush assembly is joined to the extending tube connected with the handle member, and the flexible hose is joined with the extending tube and the cleaner body therebetween. Accordingly, the air laden with the dust and/or the foreign substances taken in through the brush assembly usually flows into the dust collecting unit via the extending tube, the handle member, and the flexible hose.
- the suction motor installed in the cleaner body is driven, and thus a vacuum pressure is generated in a motor chamber of the vacuum cleaner.
- the vacuum pressure is transmitted to the brush assembly through the air passage members.
- the air and the dust and/or the foreign substances on the surface to be cleaned are taken in through the brush assembly, and then flow into the cleaner body via the air passage members. While the taken-in air and the dust and/or the foreign substances pass through the air passage members, noises occur at various places of the air passage members. Particularly, the noises occur at the brush assembly and connecting portions between the brush assembly and the extending tube, between the extending tube and handle member, between the handle member and the flexible hose, and between the flexible hose and the cleaner body.
- the shape of air path is therefor changed, so that the noises generated at the respective connecting portions may occur in different magnitudes or levels according to usage of the vacuum cleaner.
- Japanese patent publication No. H02-307418 discloses a noise absorbing apparatus of an extending tube, in which a portion of the extending tube is cut to form a plurality of holes thereon and a noise absorbing member is mounted thereto.
- Korean patent No. 10-0120616 discloses a structure having a noise absorbing material mounted on an inner circumferential surface of a neck part of the brush assembly to absorb noises generated from air flowing into the brush assembly.
- these conventional absorbing apparatuses are configured so as not to change the mounting positions thereof, as well as to have complicatedly mounted constructions.
- vacuum cleaners having the conventional absorbing apparatuses are disadvantageous in that they can reduce noises generated at places where the absorbing apparatuses are mounted at first, but cannot change the mounting positions of the absorbing apparatuses according to noise generating positions varied while using them.
- the vacuum cleaners having the conventional absorbing apparatuses are disadvantageous in that they are inconvenient for maintenance and repair because the noise absorbing apparatus or the noise absorbing material is fixedly mounted to the extending tube or the brush assembly, thereby making the noise absorbing apparatuses difficult to clean.
- an aspect of the present invention is to provide a vacuum cleaner having a noise absorbing apparatus capable of changing a mounting position thereof between connecting portions for an extending tube, a handle member, and a flexible hose, which are coupled between a cleaner body and a brush assembly so that the vacuum cleaner body and the brush assembly can communicate with each other.

- the noise absorbing apparatus is disposed to be able to change a mounting position thereof between the air passage members. Accordingly, the vacuum cleaner can be conveniently used because a user can simply change the mounting position of the noise absorbing apparatus according to noise generating positions varied while using the cleaner. Also, the vacuum cleaner is advantageous in that it is convenient for maintenance and repair because only the noise absorbing apparatus can be simply separated for repair or replacement.
- the air passage members may include an extending tube, a flexible hose and a handle member, and the noise absorbing apparatus may be detachably disposed between the brush assembly and the extending tube.
- the noise absorbing apparatus may be detachably disposed between the extending tube and the handle member, between the handle member and the flexible hose, between the flexible hose and the cleaner body.

Abstract
Description
- The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a noise absorbing apparatus, which is disposed on an air path between a cleaner body and a brush assembly to absorb noises generated from the vacuum cleaner.
- Generally, a vacuum cleaner takes in air laden with dust and/or foreign substances from a surface to be cleaned by using a suction force generated from a suction motor, and separates the dust and/or the foreign substances from the air. The vacuum cleaner can be classified into an upright type vacuum cleaner, a canister type vacuum cleaner, a stick type vacuum cleaner, etc., according to a shape thereof. The canister type vacuum cleaner is provided with a cleaner body, a brush assembly, and air passage members. The cleaner body has a suction motor and a dust collecting unit therein. The brush assembly comes in contact with a surface to be cleaned and thus takes in dust and/or foreign substances from the surface to be cleaned. The air passage members are disposed between the cleaner body and the brush assembly to guide the air taken in through the brush assembly toward the cleaner body. The air passage members are usually made up of an extending tube, a handle member, and a flexible member. That is, the brush assembly is joined to the extending tube connected with the handle member, and the flexible hose is joined with the extending tube and the cleaner body therebetween. Accordingly, the air laden with the dust and/or the foreign substances taken in through the brush assembly usually flows into the dust collecting unit via the extending tube, the handle member, and the flexible hose.
- If the cleaner is operated, the suction motor installed in the cleaner body is driven, and thus a vacuum pressure is generated in a motor chamber of the vacuum cleaner. The vacuum pressure is transmitted to the brush assembly through the air passage members. When the vacuum pressure is transmitted to the brush assembly as described above, the air and the dust and/or the foreign substances on the surface to be cleaned are taken in through the brush assembly, and then flow into the cleaner body via the air passage members. While the taken-in air and the dust and/or the foreign substances pass through the air passage members, noises occur at various places of the air passage members. Particularly, the noises occur at the brush assembly and connecting portions between the brush assembly and the extending tube, between the extending tube and handle member, between the handle member and the flexible hose, and between the flexible hose and the cleaner body. Since the dust and/or the foreign substances, such as a hair or the like, is adhered or stuck to the respective connecting portions the shape of air path is therefor changed, so that the noises generated at the respective connecting portions may occur in different magnitudes or levels according to usage of the vacuum cleaner.
- To reduce the noises generated on the air path between the brush assembly and the cleaner body,
Japanese patent publication No. H02-307418 Korean patent No. 10-0120616 - The present invention has been developed in order to solve the above problems in the related art. Accordingly, an aspect of the present invention is to provide a vacuum cleaner having a noise absorbing apparatus capable of changing a mounting position thereof between connecting portions for an extending tube, a handle member, and a flexible hose, which are coupled between a cleaner body and a brush assembly so that the vacuum cleaner body and the brush assembly can communicate with each other.
- Another aspect of the present invention is to provide a vacuum cleaner having a noise absorbing apparatus, which has a simplified construction, which is easy to separate, and which is convenient for maintenance and repair.
- The above aspect is achieved by providing a vacuum cleaner including a cleaner body having a suction source therein, a brush assembly adapted to come in contact with a surface to be cleaned and thus to take in air laden with dust and/or foreign substances, air passage members disposed between the cleaner body and the brush assembly, and a noise absorbing apparatus disposed between the air passage members. The noise absorbing apparatus is disposed to be able to change a mounting position thereof between the air passage members. Accordingly, the vacuum cleaner can be conveniently used because a user can simply change the mounting position of the noise absorbing apparatus according to noise generating positions varied while using the cleaner. Also, the vacuum cleaner is advantageous in that it is convenient for maintenance and repair because only the noise absorbing apparatus can be simply separated for repair or replacement.
- Here, the air passage members may include an extending tube, a flexible hose and a handle member, and the noise absorbing apparatus may be detachably disposed between the brush assembly and the extending tube.
- Alternatively, the noise absorbing apparatus may be detachably disposed between the extending tube and the handle member, between the handle member and the flexible hose, between the flexible hose and the cleaner body.
- According to an exemplary embodiment of the present invention, the noise absorbing apparatus includes a noise absorbing apparatus body formed in the form of a pipe having a plurality of holes in an outer circumferential surface thereof, a first cover member disposed to wrap the outer circumferential surface of the noise absorbing apparatus body, a noise absorbing member disposed between the noise absorbing apparatus body and the first cover member, and locking means disposed at the noise absorbing apparatus body, so that the noise absorbing apparatus body is detachably joined with the air passage members.
- Here, the locking means may be configured to include a supporting member disposed on the noise absorbing apparatus body, a lever member rotatably disposed at an upper side of the supporting member, an elastic member disposed between the noise absorbing apparatus body and the lever member, and a second cover member disposed to wrap the lever member.

First, when a user pushes a pushing part 45bb of thebrush assembly 40, a lever member 45b of thebrush assembly 40 rotatably disposed to a supportingmember 45a of thebrush assembly 40 is rotated in a clockwise direction, and thus a brush assembly projection 45bc is rotated in the clockwise direction by a predetermined angle. In this state, when afront side 50a of the noise absorbingapparatus body 51 is inserted into theneck part 41 of thebrush assembly 40 and then thecoupling groove 59 of thenoise absorbing apparatus 50 and thecoupling hole 47 of thebrush assembly 40 are aligned, the user removes an external force exerted on the pushing part 45bb of thebrush assembly 40. When the external force is removed as described above, the brush assembly projection 45bc is rotated in a counterclockwise direction and then inserted into the coupling holes 47 of the brush assembly and thecoupling groove 59 of thenoise absorbing apparatus 50 by an elastic force of aspring member 45c of thebrush assembly 40. As a result, thebrush assembly 40 and thenoise absorbing apparatus 50 are detachably joined with each other. After that, the user carries out the same operation as described above by using the locking means 55 of thenoise absorbing apparatus 50, so that arear side 50b of thenoise absorbing apparatus 50 and afront side 30a of the extendingtube 30 are joined with each other. - To be more specific, when the user pushes the pushing part 55bb of the
noise absorbing apparatus 50, thelever member 55b rotatably disposed to the supportingmember 55a of thenoise absorbing apparatus 50 is rotated in a clockwise direction, and thus the noise absorbing apparatus projection 55bc is rotated in the clockwise direction by a predetermined angle. In this state, when thefront side 30a of the extendingtube 30 is inserted into therear side 50b of thenoise absorbing apparatus 50 and then thecoupling groove 39 of the extendingtube 30 and thecoupling hole 57 of thenoise absorbing apparatus 50 are aligned, the user removes an external force exerted on the pushing part 55bb of thenoise absorbing apparatus 50. When the external force is removed as described above, the noise absorbing apparatus projection 55bc of thenoise absorbing apparatus 50 is rotated in a counterclockwise direction and then inserted into the coupling holes 57 of thenoise absorbing apparatus 50 and thecoupling groove 39 of the extendingtube 30 by an elastic force of thespring member 55c of thenoise absorbing apparatus 50. As a result, thenoise absorbing apparatus 50 and the extendingtube 30 are detachably joined with each other. - Alternatively, as illustrated in FIG. 3, the
noise absorbing apparatus 50 can be moved and mounted between the extendingtube 30 and thehandle member 60. In this case, first, the user separates thenoise absorbing apparatus 50 mounted between the extendingtube 30 and thebrush assembly 40 as illustrated in FIG. 1 therefrom. The separating operation is carried out contrary to the mounting operation as described above. That is, after the pushing part 55bb of the locking means 55 is pushed, the extendingtube 30 is separated from therear side 50b of thenoise absorbing apparatus 50, and after the pushing part 45bb of the locking means 45 is pushed, thefront side 50a of thenoise absorbing apparatus 50 is separated from theneck part 41 of thebrush assembly 40. And then, arear side 30b of the extendingtube 30 and thefront side 50a of thenoise absorbing apparatus 50 are connected with each other by using the locking means 35 of the extending tube, and therear side 50b of thenoise absorbing apparatus 50 and a front side of thehandle member 40 are connected with each other by using the locking means 55 of thenoise absorbing apparatus 50. At this time, an operation and constructions of mounting thenoise absorbing apparatus 50 between the extendingtube 30 and thehandle member 60 are the same as those of mounting thenoise absorbing apparatus 50 between thebrush assembly 40 and the extendingtube 30 as illustrated in FIGS. 1 and 2. - Further, as illustrated in FIG. 4, the
noise absorbing apparatus 50 can be moved and detachably mounted between thehandle member 60 and theflexible hose 20. In this case, arear side 60b of thehandle member 60 and thefront side 50a of thenoise absorbing apparatus 50 are connected with each other by using the locking means 65 of thehandle member 60, and therear side 50b of thenoise absorbing apparatus 50 and afront side 20a of theflexible hose 20 are connected with each other by using the locking means 55 of thenoise absorbing apparatus 50. At this time, an operation and constructions of mounting thenoise absorbing apparatus 50 between thehandle member 60 and theflexible hose 20 are the same as those of mounting thenoise absorbing apparatus 50 between thebrush assembly 40 and the extendingtube 30 as illustrated in FIGS. 1 and 2. - Also, as illustrated in FIG. 5, the
noise absorbing apparatus 50 can be moved and detachably mounted between theflexible hose 20 and thecleaner body 10. In this case, arear side 20b of theflexible hose 20 and thefront side 50a of thenoise absorbing apparatus 50 are connected with each other by using the locking means 25 of theflexible hose 20, and therear side 50b of thenoise absorbing apparatus 50 and the connectingpart 11 of thecleaner body 10 are connected with each other by using the locking means 55 of thenoise absorbing apparatus 50. At this time, an operation and constructions of mounting thenoise absorbing apparatus 50 between theflexible hose 20 and thecleaner body 10 are the same as those of mounting thenoise absorbing apparatus 50 between thebrush assembly 40 and the extendingtube 30 as illustrated in FIGS. 1 and 2. - The
front side 50a of thenoise absorbing apparatus 50 is configured to have an outer diameter almost equal to an inner diameter of theneck part 41 of thebrush assembly 40, so that it can be inserted into theneck part 41 of thebrush assembly 40. Also, inner diameters of therear sides tube 30, thehandle member 60, and theflexible member 20 are the same as that of theneck part 41 of thebrush assembly 40. Accordingly, thefront side 50a of thenoise absorbing apparatus 50 can be inserted into all of theneck part 41 and therear sides tube 30, thehandle member 60, and theflexible member 20. - Also, the
rear side 50b of thenoise absorbing apparatus 50 is configured to have an inner diameter almost equal to an outer diameter of thefront side 30a of the extendingtube 30, so that it can accommodate thefront side 30a of the extendingtube 30 therein. Also, an outer diameter of the connectingpart 11 and outer diameters of thefront sides handle member 60 and theflexible member 20 are the same as that of thefront side 30a of the extendingtube 30. Accordingly, therear side 50b of thenoise absorbing apparatus 50 can accommodate all of the connectingpart 11 and thefront sides tube 30, thehandle member 60, and theflexible member 20. - Hereinafter, a noise absorbing mechanism according to airflow when the
noise absorbing apparatus 50 according to the exemplary embodiment of the present invention is detachably mounted between thebrush assembly 40 and the extendingtube 30 will be explained with reference to FIGS. 1, 2 and 6. - Referring to FIGS. 1 and 2, if an external air is taken in through the
brush assembly 40, the external air and dirt and/or foreign substances laden therein generate noises while passing through thebrush assembly 40 and the air passage members. The noises generated as described above are transmitted to the outside through theholes 58 of the noise absorbingapparatus body 51. However, since the noises are absorbed by thenoise absorbing member 52 wrapping theholes 58, they can be greatly reduced. - FIG. 6 is a graph exemplifying experiment data on a noise reducing effect in a vacuum cleaner, in which the
noise absorbing apparatus 50 according to the exemplary embodiment of the present invention is mounted between thebrush assembly 40 and the extendingtube 30. In the graph, a solid line represents values of dBA according to frequencies when thenoise absorbing apparatus 50 is not mounted between thebrush assembly 40 and the extendingtube 30, and a dotted line represents values of dBA according to frequencies when thenoise absorbing apparatus 50 is mounted therebetween. As apparent from the graph, it could be appreciated that the values of dBA when thenoise absorbing apparatus 50 is mounted between thebrush assembly 40 and the extendingtube 30 were lower over the entire frequency bands, as compared with those when thenoise absorbing apparatus 50 is not mounted therebetween. - In addition, since the values of dBA were decreased at a high frequency band among the entire frequency bands, noises stimulating the nerves of human body could be reduced. Accordingly, listing noises to which the user responds were greatly reduced. Also, as apparent from the graph, it could be appreciated that the values of dBA were greatly decreased at a low frequency band, which represent a large level of noises among the entire frequency band. This means that the
noise absorbing apparatus 50 reduces noises at the low frequency band, which determines the entire level of noises. - As apparent from the foregoing description, according to the exemplary embodiments of the present invention, the vacuum cleaner is configured, so that the noise absorbing apparatus is detachably mounted between the brush assembly and the extending tube, or between the extending tube and the handle member, or between the handle member and the flexible hose, or between the flexible hose and the cleaner body. Accordingly, the mounting position of the noise absorbing apparatus of the vacuum cleaner according to the exemplary embodiments of the present invention can be changed to the place on the air path connecting the brush assembly and the cleaner body from which noises are intensively generated, thereby allowing an improvement in the noise reducing efficiency.
- Also, the vacuum cleaner according to the exemplary embodiments of the present invention is convenient for maintenance and repair because the noise absorbing apparatus can be detachably mounted between the brush assembly and the extending tube, or between the extending tube and the handle member, or between the handle member and the flexible hose, or between the flexible hose and the cleaner body.
- The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims.
