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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

Also, the second cover member 55d is disposed to cover an upper part of the lever member 55b.
  • the locking means 25, 65, 35 and 45 of the flexible hose 20, the handle member 60, the extending tube 30, and the brush assembly 40 are made up of the same apparatus and constructions as those of the locking means 55 of the noise absorbing apparatus 50.
