Definitions

  • the present invention relates to an electric vacuum cleaner.
  • a conventional electric vacuum cleaner is formed of an electric blower generating a suction wind and a cyclone dust collector placed on an upstream side of the blower. An airflow containing dust flows into the cyclone dust collector, and this airflow circles within the dust collector for the dust to be centrifuged, so that the dust remains in the collector while the air is discharged outside the collector.
  • the cyclone dust collector is connected to the blower via an air duct.
  • the air having undergone the centrifugal separation flows to the blower through this air duct (e.g. refer to Patent Literature 1.)
  • a wind noise produced at an intake port of the blower travels through the air duct or on the inner wall of the air duct to the exterior of the vacuum cleaner.
  • the conventional electric vacuum cleaner thus has a problem of producing a loud noise.
  • Patent Literature 1 Unexamined Japanese Patent Publication No. 2010 - 99183
  • An electric vacuum cleaner of the present invention comprises the following structural elements:
  • the foregoing structure allows a wind noise produced at an intake port of the blower to travel through the multiple openings formed in the communicating section, and thereby resonating the air in the space.
  • This mechanism results in an effect similar to that of a Helmholtz resonator, so that the wind noise of high frequency can be attenuated and lowered.
  • Blower 2 is supported by front supporter 22 at the front and by rear supporter 23 at the rear. Both of supporters 22 and 23 are made of elastic material. The front of blower 2 is sandwiched by motor housing right 24 and motor housing left 25 for lowering the noises produced in blower 2.
  • Sound deadening box 26 includes filter 28 for trapping fine dust contained in exhausted air from blower 2.
  • the air passes through filter 28, which removes the fine dust, and then passes through discharge path 29 shown in Fig. 4 and formed at the lower section of sound deadening box 26.
  • the air is then discharged outside cleaner body 1 via discharge port 31 formed at housing 30 that is a part of the rear outer shell of cleaner body 1.
  • communicating section 33 is provided for forming air duct 32 through which the air flows from dust collector 4 to blower 2.
  • air duct 32 is disposed between blower 2 and dust collector 4.
  • Lattice-like communicating port 34 is formed as shown in Fig. 5 approximately in front of blower 2. This port 34 communicates with intake port 2a of blower 2.
  • Fig. 6 shows, multiple openings 35 are formed in communicating section 33 confronting intake port 2a. Openings 35 are ranged from a place confronting intake port 2a to a place in the vicinity of communicating port 34.
  • space 36 communicating with air duct 32 is provided adjacently to communicating section 33.
  • Space 36 is formed of communicating section 33 and space forming section 37.
  • Space forming section 37 is formed of space forming rib 38 and space forming face 39.
  • Rib 38 is formed in communicating section 33 such that it surrounds the region in which openings 35 are provided. Space forming faces 38 confronts communicating section 33.
  • sealable member 40 is provided between space forming face 39 of upper housing 15 and space forming rib 38. Sealable member 40 prevents the suction wind from leaking.
  • Space 36 is formed by layering the communicating section 33, sealable member 40, and upper housing 15 in this order. This structure allows assembling cleaner body 1 with ease, and preventing reliably the suction wind from leaking.
  • upper cover 41 which is a part of the outer shell of cleaner body 1, and cap 42 are provided, so that multiple wall-like faces work as noise-blocking walls against the noise produced in cleaner body 1. As a result, the noise is further prevented from leaking through the outer shell.
  • Communicating section 33 includes multiple openings 35 ranged from the place confronting intake port 2a of blower 2 to a place in the vicinity of communicating port 34.
  • This structure allows the wind noise produced at intake port 2a to travel to openings 35 via the shortest route, and the wind noise passes through openings 35, thereby resonating the air in space 36.
  • This mechanism produces an effect similar to that of the Helmholtz resonator, so that the wind noise of high frequency can be attenuated.
  • the shape of each opening 35 can be round or polygon with the same effect maintained.
  • An outer shell of dust collector 4 is formed of dust box 43, upper lid 18, grip 19, and bottom lid 44.
  • Upper lid 18 covers the top face of dust box 43, and grip 19 is provided to upper lid 18.
  • Bottom lid 44 covers the underside of dust box 43.
  • first stage filter 45 and extension part 46 under filter 45 are mounted inside dust box 43 by welding or engagement with a claw (not shown).
  • second stage filter 47, dust removing section 48, and motor 49 are provided above the first stage filer 45.
  • Dust removing section 48 drops the dust accumulated in second stage filter 47 by means of vibration, and motor 49 applies the vibration to dust removing section 48.
  • the air containing dust is sucked from a suction port (not shown) of dust box 43 into cyclone space 50.
  • a circling flow produced by the first stage filter 45 separates the air containing dust into the dust chiefly formed of dust balls and the air still containing fine dust.
  • the dust chiefly formed of dust balls travels through dust collecting path 51 and is accumulated in dust accumulation space 52.
  • the dust chiefly formed of dust balls is prevented from flying back to cyclone space 50 by a wall formed vertically above space 50.
  • This wall is formed of extension part 46 and slant part 53, and increases an efficiency of dust collection.
  • Extension part 46 is mounted to first stage filter 45, and slant part 53 is provided to dust box 43.
  • the fine dust contained in the air having passed through first stage filter 45 is filtered by second stage filter 47, and only the air free from the fine dust passes through second stage filter 47 and then this air passes through communicating port 34 shown in Fig. 4 before it is sucked by blower 2.
  • the fine dust accumulated in second stage filter 47 is removed therefrom by the vibration applied to dust removing section 48, and passes through first stage filter 45 before it is accumulated in tube 54 disposed under filter 45.
  • a cyclone dust collector is used as dust collector 4; however, a dust collector employing a sack, e.g. paper bag, also can lower the noise in operation.
  • the electric vacuum cleaner of the present invention lowers the noise in operation, so that it is useful for a household-use cleaner and a business-use cleaner.
