  • 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.
  • the suction opening and the exhaust opening are formed at one side of the dust container, and the discharge conduit is installed from the exhaust opening to the discharge port of the main body such that, even when the dust container is tilted towards one side during driving of the vacuum cleaner, it is possible to prevent reduction in vacuum force caused by a loss of air, thereby enhancing an operation efficiency of the vacuum cleaner and reducing consumption of electricity.
  • the exhaust structure of the vacuum cleaner according to the present invention prevents the air leakage, an excessive number of sealing materials is not required, thereby reducing manufacturing costs.
  • 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.

Abstract

La présente invention concerne une structure d’évacuation d’un aspirateur. La structure d’évacuation de l’aspirateur comprend un corps principal (10) doté d’un orifice d’aspiration (12) et d’un orifice d’évacuation (14) formés sur celui-ci, un ventilateur d’aspiration (62) placé à l’intérieur de l’orifice d’évacuation (14), un bac à poussière (50) monté à une extrémité d’un conduit d’écoulement entre l’orifice d’aspiration (12) et celui d’évacuation (14) et doté d’une ouverture d’aspiration (52) et d’une ouverture d’évacuation (54) formées sur l’un de ses côtés, et un conduit d’évacuation (82) s’étendant entre l’ouverture d’évacuation (54) et l’orifice d’évacuation (14). La structure d’évacuation évite une réduction de la force de dépression par fuite d’air résultant de l’inclinaison d’un réservoir à poussière vers un côté, et permet une moindre utilisation d’un matériau d’étanchéité.
