Definitions

  • the present invention relates to an electric vacuum cleaner and a cyclonic dust collecting apparatus to be mounted in the electric vacuum cleaner.
  • Electric vacuum cleaners include, for example, a main body having an electric fan, a suction member to be moved along a floor surface, and a connection hose which connects the suction member to the main body, and a disposable filter bag is mounted in the main body.
  • an electric vacuum cleaner of this type When an electric vacuum cleaner of this type is driven, outside air (air on the floor surface) is sucked from the suction member by driving the electric fan provided in the main body, and taken into the main body from a suction port of the main body through the connection hose.
  • An inlet of the disposable filter provided in the main body communicates with the suction port. When the air sucked from the suction port passes through the disposable filter, dust entrained in the air is captured by the disposable filter (see, for example, Japanese Examined Utility Model Publication No. 5-20279 (1993)).
  • the electric vacuum cleaners of this type are uneconomical and disadvantageous in terms of environmental protection, because the cleaners utilize the disposable filter. Further, the disposable filter is not replaced until a certain amount of dust is collected in the filter. Therefore, the suction force and hence the dust collecting efficiency are reduced, as the amount of the collected dust is increased.
  • an electric vacuum cleaner including a cyclonic dust collecting apparatus which is capable of swirling air sucked from a suction port to separate dust from the air by a centrifugal force and capture the dust.
  • the dust collected in the cyclonic dust collecting apparatus can be easily discarded by detaching the dust collecting apparatus from a main body and performing a predetermined operation.
  • the electric vacuum cleaner including the cyclonic dust collecting apparatus is advantageous in that the reduction of the dust collecting efficiency is prevented by frequently discarding the dust collected in the cyclonic dust collecting apparatus (e.g., whenever the cleaner is used for a cleaning operation).
  • An electric vacuum cleaner comprises a main body including an electric fan incorporated therein, and a dust collecting apparatus removable from the main body.
  • the dust collecting apparatus comprises a suction port, a cyclonic flow path for swirling air sucked from the suction port to separate dust from the air by a centrifugal force, a dust collecting chamber in which the separated dust is collected, an air outlet port provided in a wall of the dust collecting chamber for discharging the air sucked from the suction port, and a filter attached to the air outlet port.
  • the main body has a wall opposed to the wall of the dust collecting chamber and having an opening smaller than the air outlet port in opposed relation to the air outlet port for feeding the air downstream by the electric fan.
  • the air outlet port has a region opposed to the opening and a region not opposed to the opening, and a guide passage is provided for guiding air discharged from the region of the air outlet port not opposed to the opening toward the opening.
  • the inventive electric vacuum cleaner is adapted to selectively utilize the cyclonic dust collecting apparatus and a disposable dust collecting apparatus having a mouth cardboard and a filter bag attached to the mouth cardboard.
  • the main body has an accommodating portion for accommodating either of the dust collecting apparatuses, and the accommodating portion has a fixing member for fixing the disposable dust collecting apparatus when the disposable dust collecting apparatus is mounted in the main body.

  • the opening 33 is covered with a filter 34 having a pleat structure formed by folding filter paper into a bellows shape.
  • the dust collecting apparatus 7 (casing 18 ) has the greatest possible size (the dust collecting apparatus 7 occupies a wider area of the dust collecting chamber 9 from the left side to the right side) to ensure that the air sucked from the suction port 4 of the main body 3 can be properly swirled for improvement of the dust collecting efficiency.
  • the air outlet port 19 has a great size (the air outlet port 19 is provided in the entire rear surface of the dust collecting apparatus 7 ) to ensure that the air from the dust collecting apparatus 7 can be properly discharged. Since the air outlet port 19 has a great size, the size of the filter 20 covering the air outlet port 19 can be increased. Therefore, clogging of the filter 20 can be suppressed.

Therefore, the opening 33 formed in the rear wall 9 B has a smaller size than the air outlet port 19 . In this case, a portion of the air outlet port 19 opposed to the opening 33 ensures proper air flow to the opening 33 through the filter 20 , but the other portion of the air outlet port 19 not opposed to the opening 33 is liable to prohibit the proper air flow.

Therefore, the air flow from the portion of the air outlet port 19 not opposed to the opening 33 can be ensured by the guide passage 35 , thereby suppressing the reduction of the suction force to improve the dust collecting efficiency.
  • the rear surface of the filter holder 18 B abuts against the rear wall 9 B, so that the dust collecting apparatus 7 can be firmly fixed in the dust collecting chamber 9 .
  • the guide passage 35 can be defined by the space between the vertical ribs 32 A and the filter 20 .
  • peripheral rib 32 C of the filter holder 18 B intrudes into the rear surface of the filter 20 , there is no gap between the peripheral portion of the filter 20 and the filter holder 18 B. Therefore, the peripheral rib 32 C serves as a barrier to prevent the dust from leaking from the dust collecting apparatus 7 between the peripheral portion of the filter 20 and the filter holder 18 B.
  • the vertical ribs 32 A and the transverse ribs 32 B which serve as a filter cover are formed integrally with the filter holder 18 B.
  • the number of components can be reduced, thereby reducing the production costs.
  • a portion (left portion) of the dust collecting portion 23 not opposed to the opening 33 is narrower than a portion (right portion) of the dust collecting portion 23 opposed to the opening 33 .
  • the space of the dust collecting portion 23 has a cross section which progressively decreases toward the portion of the dust collecting portion 23 not opposed to the opening 33 (see FIG. 2 ).
  • the air swirled in the dust collecting apparatus 7 tends to flow toward a narrower space.
  • the air can be positively guided toward the portion of the air outlet port 19 not opposed to the opening 33 in which the air communication is poorer, so that the air can be discharged from the entire air outlet port 19 including not only the portion of the air outlet port 19 opposed to the opening 33 but also the portion of the air outlet port 19 not opposed to the opening 33 .
  • the collected dust is also guided toward the narrower space. Therefore, the dust is first gradually accumulated in the space not opposed to the opening 33 , and finally captured by the entire filter 20 .
  • the dust collecting efficiency is improved.
  • the construction of the dust collecting apparatus 7 is not limited to the construction described above, but the dust collecting apparatus 7 may have the same construction as a dust collecting apparatus 107 according to a second embodiment to be described in detail with reference to FIGS. 8 to 10 .
