  • the suction opening is formed at the upper portion of the dust container, and the exhaust opening is formed at the lower portion thereof, a vacuum force increases during driving of the vacuum cleaner, and causes an increase in shielding force at the suction opening, which results in a problem of reducing the suction force of the vacuum cleaner.
  • the present invention has been made in view of the above problems of the conventional vacuum cleaner, and it is an object of the present invention to provide an exhaust structure of a vacuum cleaner, in which suction and exhaust openings are formed at one side of a dust container, thereby preventing air leakage at a connecting portion around the exhaust opening even when a dust container is tilted to the suction opening side by a vacuum force, and reducing use of a sealing material.
  • an exhaust structure of a vacuum cleaner comprising: a main body having a suction port and a discharge port formed thereon; a suction fan positioned inside the discharge port; a dust container mounted at one side of a flow passage between the suction port and the discharge port and having a suction opening and an exhaust opening formed at one side thereof; and an exhaust conduit extending between the exhaust opening and the discharge port.
  • the suction port is formed at an upper end of the main body, and the discharge port is formed at a lower front side of the main body, the main body having a mounting part formed between the suction port and the discharge port such that the dust container is detachably mounted to the mounting part of the main body in a sliding manner.
  • the exhaust structure further comprises a soft sealing material interposed between an upper surface of the exhaust conduit and the exhaust opening.
  • the exhaust structure further comprises a cover installed to a lower end of the exhaust conduit connected to the suction fan to cover an induction port of the suction fan.
  • the exhaust structure further comprises a housing fastened to the main body to define the suction fan, the housing having a discharge hole formed on a surface facing a discharge outlet of the suction fan and to which a filter is installed.
  • FIG. 1 is a perspective view illustrating a conventional upright type vacuum cleaner
  • FIG. 2 is a perspective view illustrating a dust container of the conventional upright type vacuum cleaner
  • FIG. 3 is a perspective view illustrating a vacuum cleaner according to the present invention.
  • FIG. 4 is an exploded perspective view illustrating a dust container of the vacuum cleaner according to the present invention.
  • FIG. 5 is an exploded perspective view illustrating an exhaust structure of the vacuum cleaner according to the present invention.
  • FIG. 6 is a perspective view illustrating a mounting structure of an exhaust conduit in the exhaust structure of the vacuum cleaner according to the present invention.
  • FIG. 7 is a cross-sectional view illustrating the exhaust structure of the vacuum cleaner according to the present invention.
  • FIG. 3 is a perspective view illustrating a vacuum cleaner according to the present invention
  • FIG. 4 is an exploded perspective view illustrating a dust container of the vacuum cleaner according to the present invention.
  • the vacuum cleaner comprises: a main body 10 having a predetermined space defined therein, and having a suction port 12 and a discharge port 14 ; a suction unit 15 detachably attached to a lower side of the main body 10 to stand the main body 10 upright, and having a dust collection port (not shown) and a discharge opening 18 ; a suction hose 70 positioned between the suction port 12 and the discharge opening 18 ; an extension pipe 30 detachably attached to the main body 10 and having a hollow space to define a flow passage along which dust is induced; a handle 20 detachably mounted to an upper end of the extension pipe 30 to further define the flow passage along which the dust is induced; a suction fan 62 positioned at one side of the flow passage extending from the suction port 12 to the discharge port 14 ; a dust container 50 detachably mounted at one side of the flow passage; and a filter 60 positioned inside the discharge port 14 .
  • the construction described above constitutes an upright type vacuum cleaner, as an example, to which the exhaust structure of the present invention can be applied.
  • This vacuum cleaner can be converted into a canister type vacuum cleaner in such a way that, after separating the extension pipe 30 and the handle 20 from the main body 10 , the suction hose 70 is disconnected from the discharge opening 18 , and is connected with the handle 20 , followed by separating the main body 10 from the suction unit 15 .
  • the exhaust structure of the vacuum cleaner according to the present invention can be applied to any kind of vacuum cleaner which comprises the dust collecting container and the filter, such as a general canister type vacuum cleaner and a general upright type vacuum cleaner.
  • FIG. 5 is an exploded perspective view illustrating an exhaust structure of the vacuum cleaner according to the present invention
  • FIG. 6 is a perspective view illustrating a mounting structure of an exhaust conduit in the exhaust structure of the vacuum cleaner according to the present invention

  • the suction port 12 is formed at an upper end of the main body 10 , and the discharge port 14 is formed at a lower front side thereof.
  • the main body 10 has a mounting part formed between the suction port 12 and the discharge port 14 such that the dust container 50 is detachably mounted to the mounting part of the main body in a sliding manner.
  • the mounting part 11 be slightly smaller than the dust container 50 . In this regard, when the suction fan 62 is driven, the dust container 50 is inclined towards the suction port 12 .
  • a soft sealing material 86 is disposed between an upper end of the exhaust conduit 82 and the exhaust opening 54 , preventing reduction in vacuum force due to air leakage between the exhaust conduit and the exhaust opening.
  • a cover 84 is provided to a lower end of the exhaust conduit 82 connected with the suction fan 62 to prevent air from being leaked between the suction fan 82 and the exhaust conduit 82 .
  • the cover 84 has a circular dish shape which can cover an upper side of the suction fan 62 , and is formed at one side with a protruded hole coupled to the exhaust conduit 82 , as shown in FIG. 5 .
  • a housing 64 is fastened to the main body 10 to define the front side of the suction fan 62 , and has a discharge hole 64 a formed through a surface facing a discharge outlet 62 a of the suction fan 62 such that a filter 60 is installed at a front side of the discharge hole 64 a . Accordingly, foreign substances contained in the air are secondarily filtered when they flow to the discharge port 14 through the discharge hole 64 a , thereby permitting maintenance of fresh environment in the room.
