Definitions

  • the present invention relates to a household vacuum cleaner; and, more particularly, to a vacuum cleaner having an improved usability.
  • FIGs. 18 and 19 there is shown a conventional vacuum cleaner.
  • reference numeral 1 represents a main body communicating with suction nozzle 2 through which the dirt particle are suctioned, the main body including therein an electric blower (not shown) for generating a suction air stream containing dirt particles.
  • Reference numeral 3 is a dirt collection unit detachably installed in main body 1. Dirt collection unit 3 includes centrifugal separation part 3a at an upper portion thereof, which centrifugally separates dirt particles from a suction air stream; and dirt accumulation part 3b at a lower portion thereof for accumulating the dirt particles separated from the suction air stream by centrifugal separation part 3a.
  • dirt particles are suctioned together with the suction air stream through suction nozzle 2 into dirt collection unit 3, and are centrifugally separated from the suction air stream by centrifugal separation part 3a.
  • separated dirt particles are then accumulated in dirt accumulation part 3b, while the suctioned air stream is drawn to pass through filter 3c by a suction force of the electric blower.
  • centrifugal separation part 3a and dirt accumulation part 3b is of a cylindrical shape having a longitudinal central axis extending in a substantially vertical direction (see, Japanese Patent Laid-open Publication No. 1997-176871).
  • centrifugal separation part 3a for separating dirt particles from the suction air stream and dirt accumulation part 3b for accumulating dirt particles therein need to be enlarged, thereby increasing the size of the vacuum cleaner.
  • an object of the present invention to provide a vacuum cleaner capable of scaling down a size of a dirt collection unit including a centrifugal separation part and a dirt accumulation part without deteriorating dirt collecting capability thereof and, at the same time, improving its usability.
  • a vacuum cleaner including: an electric blower for generating a suction air stream; a plurality of centrifugal separation parts for separating dirt particles from the suction air stream; and an air inlet installed upstream of the centrifugal separation parts, wherein the suction air stream suctioned in the air inlet is divided in plural streams to flow into the respective centrifugal separation parts.
  • the centrifugal separation parts In order to centrifugally collecting dirt particles, the centrifugal separation parts should have an approximately cylindrical or conical shape. Therefore, in case of a single centrifugal separation part, in order to improve dirt collecting capability, a size of the centrifugal separation part needs to be enlarged, which entails an enlarged main body.
  • reference numeral 4 represents a main body
  • reference numeral 5 represents dirt collection unit including centrifugal separation parts 7 disposed at an upper portion of main body 4 for separating dirt particles from a suction air stream and dirt accumulation part 8 placed at a lower portion of main body 4, for accumulating the dirt particles separated by the centrifugal separation parts 7.
  • Dirt collection unit 5 communicates with electric blower 6 for producing a suction air stream and with a suction nozzle (not shown) through which the dirt particles are suctioned.
  • Dirt collection unit 5 is constructed such that longitudinal central axes of centrifugal separation part 7 are inclined at an angle of 30 degrees with respect to a longitudinal central axis of dirt accumulation part 8.
  • Reference numeral 9 indicates an air inlet for introducing a suction air stream containing dirt particles suctioned through the suction nozzle into dirt collection unit 5.
  • Reference numeral 10 represents air stream separation ports for approximately uniformly distributing the suction air stream from air inlet 9 into respective centrifugal separation parts 7 at entrances thereof.
  • reference numeral 11 represents a grip unit which is used to hold and carry dirt collection unit 5;
  • reference numeral 12 indicates a dirt collection unit cover for covering openings 13 provided at an approximately upper portion of dirt collection unit 5, dirt collecting unit cover 12 including therein filter 14 for filtering dirt particles contained in the air stream suctioned therein;
  • reference numeral 15 represents a manipulation unit installed near grip unit 11, for connecting and disconnecting dirt collection unit cover 12 and dirt collection unit 5.
  • Manipulation unit 15 may include grip unit 11 and, at the same time, operate it.
  • reference numeral 16 represents approximately cylindrical pre-filters disposed between dirt collection unit 5 and dirt collection unit cover 12, pre-filters 16 being disposed on the longitudinal central axes of centrifugal separation parts 7, respectively, for accumulating bulky dirt particles.
  • Reference numeral 17 indicates approximately pan-shaped protecting members provided at lower portions of pre-filters 16, respectively.
  • reference numeral 18 indicates a discharge port provided at a peripheral portion of dirt accumulation part 8, for discharging dirt particles
  • reference numeral 19 represents a discharge port cover for covering discharge port 18.
  • Discharge port cover 19 is rotatably supported by hinge shaft 20 installed near discharge port 18, and hooks 21 for fixing discharge port cover 19 upon rotation thereof are installed near hinge shaft 20.
  • a suction air stream containing dirt particle suctioned by electric blower 6 pass through air inlet 9 and are then divided into approximately equal air streams by air stream separation ports 10 provided upstream of centrifugal separation parts 7 and the divided air streams are introduced into centrifugal separation members 7 in approximately tangential directions along inner surfaces thereof, respectively.
  • a user may choose two methods.
  • the user removes dirt collection unit 5 from main body 4 by holding and lifting grip unit 11.
  • the user separates dirt collection unit cover 12 from dirt collection unit 5. In this way, dirt particles can be discharged from opening 13 provided at an upper portion of dirt collection unit 5.
  • the user removes dirt collection unit 5 from main body 4 and opens discharge port cover 19 provided at a lower portion of dirt collection unit 5 so that dirt particles in dirt accumulation part 8 can be discharged from discharge port 18.
  • dirt collection unit 5 since dirt collection unit 5 is constructed such that the longitudinal central axes of centrifugal separation parts 7 are inclined at an angle of 30 degrees with respect to the longitudinal central axis of dirt accumulation part 8, a total height thereof can be reduced compared with a case where centrifugal separation parts 7 and dirt accumulation part 8 are arranged in line vertically. Accordingly, dirt collection unit 5 can be installed in so-called a cylinder vacuum cleaner as well as an upright vacuum cleaner. Further, although dirt collection unit 5 is constructed such that the longitudinal central axes of centrifugal separation parts 7 are inclined at an angle of 30 degrees with respect to the longitudinal central axis of dirt accumulation part 8 in this embodiment, the object of the present invention can be sufficiently satisfied with an angle ranging from 5 to 85 degrees.
  • centrifugal separation members 7 are inclined at 30° with respect to a vertical direction as illustrated in Figs. 1 to 3, dirt particles can move downward due to their own weights. As a result, it is possible to avoid a drawback that dirt particles separated from the suction air stream are not efficiently moved in case centrifugal separation parts 7 and dirt accumulation part 8 are horizontally arranged.
  • centrifugal force generated by centrifugal separation parts 7 is almost equal in upper portions and lower portions of centrifugal separation parts 7, deterioration of the dirt collecting capability can be reduced.
  • centrifugal separation parts 7 are inclined while a shape of dirt accumulation part 8 can be freely designed without any limits. Therefore, by enlarging dirt accumulation part 8 as great as possible, a dirt collecting volume of dirt collection unit 5 can be increased. Accordingly, a frequency of discarding dirt particles is reduced so that the usability of the vacuum cleaner can be improved.
  • dirt collection unit 5 With reference to Figs. 4 and 5, by horizontally arranging dirt collection units 5 having a thin configuration parallel to each other, entire dirt collection unit 5 can be of an approximately rectangular shape in section with round corners, as shown in Fig. 5. Thus, it is possible to design, dirt collection unit 5 variously. Specifically, arrangements of a plurality of dirt collection units 5 or dirt collection units 5 of different sizes can be implemented to increase variety of design and, at the same time, dirt collection unit 5 can be installed even in a small space.
  • centrifugal separation parts 7 In order to centrifugally collect dirt particles, centrifugal separation parts 7 should have an approximately cylindrical shape or an approximately conical shape. Thus, in case of a single centrifugal separation part, in order to improve dirt collecting capability, a size of centrifugal separation parts 7 and should be increased, resulting in an enlarged main body. However, with the above-described configuration, especially, by providing a plurality of centrifugal separation parts 7, a degree of freedom of arrangement is increased so that a compact arrangement can implemented without deteriorating dirt collecting capability.
  • grip unit 11 which is used to hold and carry dirt collection unit 5 is provided at dirt collection unit 5, so that it is easy to carry dirt collection unit 5. Further, in case dirt particles are discarded, since hands of the user are prevented from being contaminated, the usability thereof can be improved.
  • openings 13 are provided at an approximately upper portion of dirt collection unit 5 and dirt collection unit cover 12 is provided which covers openings 13 and includes therein filter 14 for filtering fine dirt particles in the air streams separated by centrifugal separation parts 7, it is possible to eliminate drawbacks such as performance degradation and stability deterioration due to an adhesion of fine dirt particles to electric blower 6. At the same time, by separating dirt collection unit cover 12, it is easy to discard dirt particles accumulated in dirt collection unit 5 from openings 13, thereby improving the usability thereof.
  • Manipulation units 15 for connecting and disconnecting dirt collection unit cover 12 and dirt collection unit 5 are installed near grip unit 11 of dirt collection unit 5, so that manipulation unit 15 can be manipulated to separate dirt collection unit cover 12 from dirt collecting unit 5 while holding grip unit 11 as shown in Fig. 6. As a result, when dirt particles are discarded, it is unnecessary to use the other hand on purpose, thereby improving the usability thereof.
  • pre-filters 16 dirt particles, which may be adhered to filter 4 in dirt collection unit cover 12 without being separated by centrifugal separation parts 7 to cause performance degradation thereof, are accumulated by pre-filters 16. Therefore, dirt particles adhered to filter 14 can be reduced so that the performance degradation can be avoided. Further, by forming pre-filters 16 of an approximately cylindrical shape, an area of pre-filters 16 can be enlarged and, therefore, it is possible to prevent the performance degradation thereof due to dirt particles accumulated to pre-filters 16.
  • pan-shaped protecting members 17 With a surface approximately perpendicular to the longitudinal central axes of centrifugal separation parts 7. Accordingly, when dirt particles carried into dirt accumulation part 8 by rotational air current generated by centrifugal separation parts 7 are floated upward by the rotational air current reflected by the bottom surface of dirt accumulation part 8, protecting members 17 block the ascending air current in front of centrifugal separation parts 7 and allows the rotational air current to move down. As a result, it is possible to avoid a problem that the dirt particles return to centrifugal separation parts 7 to disturb separation of newly suctioned dirt particles.
  • pan-shaped protecting members 17 With a surface approximately perpendicular to the longitudinal central axes of dirt accumulation part 8.
  • dirt particles which are separated by centrifugal separation parts 7 to be carried into underlying dirt accumulation part 8 by the rotational air current generated by centrifugal separation parts 7, are floated upward again by the rotational air current reflected by the bottom surface of dirt accumulation part 8, protecting members 17 block the ascending air current in front of centrifugal separation parts 7 and allows the rotational air current to move down.
  • FIGs. 9 and 10 there is installed at a peripheral portion of dirt accumulation part 8 discharge port 18 for discharging dirt particles accumulated therein and discharge port cover 19 for covering discharge port 18.
  • discharge port cover 19 By opening discharge port cover 19, dirt particles accumulated in dirt accumulation part 8 can be easily discarded from discharge port 19 provided at a lower portion of dirt collection unit 5, thereby improving the usability thereof.
  • discharge port 18 at a rear surface of dirt accumulation part 8, even though discharge port cover 19 is opened, dirt particles therein are not unintentionally discarded. Instead, a user can control a desired amount and speed of discharge of the dirt particles, so that it is possible to solve a problem that dirt particles are scattered, resulting in an improvement of the usability.
  • the first embodiment describes a canister vacuum cleaner in which dirt collection unit 5 is vertically arranged. However, the same effects can be obtained by using an upright vacuum cleaner.
  • Figs. 11 and 13 provide cross-sectional views of principal parts of a main body of the vacuum cleaner in accordance with the second embodiment.
  • Figs. 12 and 14 to 17 present cross-sectional views of principal parts of a dirt collection unit attached to the main body.
  • the grip unit is installed at a rear portion of dirt collection unit 5
  • a grip unit is installed at an upper portion of dirt collection unit 5 in this embodiment.
  • reference numeral 4 indicates a main body including therein electric blower 6 for suctioning dirt particles
  • reference numeral 5 represents a dirt collection unit detachably attached to main body 4, dirt collection unit communicating with a suction nozzle (not shown) through which dirt particles are suctioned
  • reference numeral 30 represents a grip unit having hinge shaft 31 at one end portion thereof and stopper 32 for controlling a rotation angle at the other end portion thereof
  • reference numeral 33 indicates a buckle for keeping the connection of dirt collection unit 5 with main body 4.
  • grip unit rib 34 is separated from top surface 35 by rotating grip unit 30, if buckle 33 rotates about central axis 38 provided at an approximately central portion of buckle 33, claw 36 installed at buckle 33 is separated from buckle hook 37 installed at main body 4, thereby separating dirt collection unit 5 from main body 4.
  • buckle 33 has a length corresponding to a distance from central axis 38 to claw 36, buckle 33 can be elastically deformed enough to go beyond a stepped portion of buckle hook 37 despite of its fixed state.
  • Reference numeral 39 represents a grip unit hook for maintaining grip unit 30 in an irrotational state and preventing grip unit 30 from rotating unintentionally due to an accidental impact or vibration.
  • Box 44 for covering buckle 33 is installed at dirt collection unit 5, and main box 45 is installed at main body 4.
  • Main box 45 is disposed inside box 44 for maintaining box 44 while dirt collection unit 5 is attached to main body 4. Further, the box 44 is constructed such that it is contacted with main box 45 before buckle 33 is contacted with buckle hook 37 of main body 4.
  • grip unit 30 When dirt particles accumulated in dirt collection unit 5 are discarded, grip unit 30 is lifted upward so that it rotates about hinge shaft 31 as shown in Fig. 13. By such rotation of grip unit 30, grip unit rib 34 is separated from top surface 35 as illustrated in Fig. 14. Accordingly, buckle 33 rotates about central axis 38 provided at an approximately central portion of buckle 33, thereby separating claw 36 installed at buckle 33 from buckle hook 37 provided at main body 4. As a result, dirt collection unit 5 and main body 4 are disconnected so that dirt collection unit 5 can be removed from main body 4.
  • Buckle 33 has a length corresponding to a distance from central axis 38 to claw 36. Therefore, in the irrotational state of grip unit 30, i.e., in case dirt collection unit 5 is attached to main body 4 with buckle 33 fixed, when buckle 33 moves beyond the stepped portion of buckle hook 37 of main body 4, it is elastically deformed as shown in Fig. 15. Accordingly, claw 36 can be retained by buckle hook 37 without being damaged, so that it is possible to provide a highly reliable vacuum cleaner.
  • buckle 33 is forcibly rotated to completely separate dirt collection unit 5 from main body 4. Accordingly, there is no obstacle while dirt collection unit 5 is removed from main body 4, thereby improving the usability thereof.
